It thus aims to provide historical background to current debate about for instance the retirement age and how to best care for the elderly.&lt;br/&gt;&lt;br&gt; Encyclopaedia entries from both the beginning and the end of this period describe ageing as a medical process of physical decline. Since much current research also uses such a medical perspective on ageing, it is tempting to conclude that ageing always was (and is) seen as a medico-biological phenomenon of physical decline. But has this medical perspective always dominated? The three sources studied in this thesis show that this was not always the case. The sources were birthday notices for women and men aged sixty or more, application letters to private old-age homes and, lastly, legislative material related to reforms for elderly people.&lt;br/&gt;&lt;br&gt; Rather than establishing certain a priori criteria before conducting the empirical analyses – methods often used in previous historical research – I approached old age and ageing indirectly by examining related expressions. The theoretical perspective of the thesis builds on the work of, among others, German historian Reinhart Koselleck and British historian Quentin Skinner. The approach relies on the assumption of a mutual relationship between language and reality, and on the agency of individuals. I call this perspective “linguistic-historical research” (“språkhistorisk forskning”) to underline its reliance on both language and historical context.&lt;br/&gt;&lt;br&gt; The analyses show that old age and ageing tended to be linked to the body and to chronology, alternating and combining the two, with no apparent evolution in a specific direction. By contrast, it is possible to discern a trend from societal to more individual manifestations of old age and ageing. Furthermore, the sources more than once exhibit a correspondence between the manifestations of old age and ageing, and contemporary ideas and events. This thesis therefore suggests that old age and ageing have not had a single well-defined essence at any point in time. Rather, their understanding and manifestations have changed with time, situation and person. &lt;br/&gt;&lt;br&gt; Returning to my initial question, the thesis shows that medical perspectives on ageing were clearly distinguishable only towards the 1950s. Finally, the sources shed light on two common hypotheses: that women were perceived to age earlier than men, and that retirement could be seen as a form of “social ageing”. The three sources do not support either hypothesis.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;Vad är åldrande? När började man över huvud taget tala om ”åldrande”? När fick ordet ”pensionär” den betydelse vi är vana vid idag?&lt;br/&gt; I Åldrandet och språket studeras ord och uttryck för att ringa in vad man har menat med hög ålder och åldrande i Sverige under hundraårsperioden mellan 1875 och 1975. Frågor kring hög ålder och åldrande har stor aktualitet idag. I Sverige och Europa talar politiker om ökade kostnader för äldrevården och om behovet av att höja pensionsåldern i takt med att medellivslängden stiger. I avhandlingen ges en historisk bakgrund till dessa frågor – en diskussion om höjd pensionsålder fördes till exempel för mer än femtio år sedan.&lt;br/&gt; I de tre källmaterialen – födelsedagsnotiser, ansökningshandlingar till privata ålderdomshem samt statliga förslag och utredningar – har åldrandet inte haft någon distinkt och oföränderlig kärna. Medicinska perspektiv som vanligen förknippas med åldrande hade länge en undanskymd plats. I stället har idéer och händelser i det omgivande samhället påverkat hur åldrandet manifesterades i en pendelrörelse mellan kropp och kronologi. Avhandlingen visar hur förståelsen av åldrandet sett olika ut beroende på tidpunkt, person och situation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c263cb63-5fc3-4c3f-bd10-3586997ac3f3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Åldrandet och Språket.pdf">https://portal.research.lu.se/files/72830572/_ldrandet_och_Spr_ket.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">24109942</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Södertörns högskola</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Ageing</topic> <topic>cultural ageing</topic> <topic>elderly</topic> <topic>history of concepts</topic> <topic>conceptual history</topic> <topic>life-writing</topic> <topic>auto/biography</topic> <topic>retirement</topic> <topic>elderly care</topic> <topic>welfare studies</topic> <topic>Sweden</topic> <topic>19th century</topic> <topic>20th century.</topic> </subject> <subject authority="lup"> <topic>History</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Studia Historica Lundensia</title> </titleInfo> <identifier type="issn">1652-7399</identifier> <identifier type="issn">1652-7399</identifier> <identifier type="issn">1653-2147</identifier> <identifier type="isbn">978-91-86069-36-0</identifier> <identifier type="oldLupId">2203885</identifier> <part> <detail type="volume"> <number>16</number> </detail> <extent unit="pages"> <total>234</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-12-16T10:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>c263cb63-5fc3-4c3f-bd10-3586997ac3f3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T09:56:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T09:56:31+02:00</recordDateApproved> </recordInfo> </mods>

This thesis aims at contributing to research in this field, by empirically exploring what happens when students play and reflect on their computer game play in science education. Three empirical studies and a research review have been conducted. The first study was part of a design-based research project on mobile learning, and involved 17 students (aged 15−16) playing the mobile educational game Agent O. The two following studies involved 72 students (aged 13−15) playing the COTS game SimCity 4, in connection with the annual Swedish school competition Future City. Research questions aimed at clarifying, in a science learning context, what aspects of scientific practice are: (1) mediated through computer game play; (2) used and referred to by students, when reflecting upon their actions during computer game play. This work is not about science education. Instead, it studies actions mediated by computer games, and possible implications for science education. The focus is on mediated actions that occur during computer game play and their potential relevance to school science learning. Two tendencies are important as a background to the thesis. Firstly, the rapidly increased use of digital media among young people. Secondly, the challenge digital media pose for education, generally, and in this case science education, more particularly. The results suggest a number of ways in which computer game play can play a role in science education. Findings show that computer games may provide platforms for engagement in scientific practice, support authentic experiences, and constructively constrain students’ actions, by confronting them with simulated complexities. Computer game play is an activity of great variation, that can take many directions, and outcomes may therefore correspond to teachers’ expectations in some cases, while leading to quite different outcomes in others. It is noteworthy that during game play the students in these studies were primarily playing a game, not simulating a “real” world situation. They did not relate to occurrences outside the game world, unless they were specifically instructed to do so. Conclusions further indicate that instruction is a crucial factor, to benefit from potentials of computer game play in educational settings.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b92cdf10-6ab3-43bc-9151-2882f273c150</url> </location> </relatedItem> <originInfo> <publisher>Malmö University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>computer game play science education computer games game-based learning</topic> <topic>Agent O</topic> <topic>empirical studies</topic> <topic>SimCity 4</topic> <topic>mediated action</topic> </subject> <subject authority="lup"> <topic>Educational Sciences</topic> </subject> <relatedItem type="host"> <location> <url>http://hdl.handle.net/2043/9993</url> </location> </relatedItem> <relatedItem type="host"> <titleInfo> <title>Malmö Studies in Educational Sciences</title> </titleInfo> <identifier type="issn">1651-4513</identifier> <identifier type="isbn">978-91-86295-02-8</identifier> <identifier type="oldLupId">1593234</identifier> <part> <detail type="volume"> <number>50</number> </detail> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-21T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>b92cdf10-6ab3-43bc-9151-2882f273c150</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T10:21:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T10:21:43+02:00</recordDateApproved> </recordInfo> </mods>

A basic assumption made in the thesis is that contemporary biomedicine is deeply embedded in the cultural, historical, economic, and political circumstances provided by the particular local, national, and transnational contexts in which it is practiced. The aim of the thesis is twofold. On the one hand, the aim is to examine the forms of person- and patienthood enacted and negotiated in haemodialysis and kidney transplantation care and in the daily lives of persons with kidney failure. On the other hand, the aim is to investigate the ways in which the enacted and negotiated forms of person- and patienthood are culturally embedded and normatively charged. &lt;br/&gt;&lt;br&gt; In order to examine and investigate this twofold aim, an empirical material has been gathered that comprises observations and in-depth interviews with patients and caregivers at four haemodialysis units, one in Riga, Latvia, and three in Stockholm, Sweden. The theoretical approach and methodology of the study is cultural and phenomenological in character, drawing on an ethnological and anthropological understanding of culture as processual and relational, and on a phenomenological understanding of personhood as embodied and intertwined with the surrounding world. &lt;br/&gt;&lt;br&gt; The thesis shows that patients’ encounters and attempts to deal with the diagnoses and treatments associated with kidney failure are complex and often misalign them with the normatively charged orientations enacted and recommended by medicine. The complex situation that emerges when they undergo transplantation, for example, stands in stark contrast to the widespread official view of organ transplantation as a self-evidently health-bringing and normalising therapy. &lt;br/&gt;&lt;br&gt; Through their repeated and extensive experiences of undergoing haemodialysis and living with the disease, patients eventually become able to create a synthesis between their lived experiences of their own body and their body as a medical object – what in the thesis is called a ‘sick body’ – a synthesis that allows them to reorient themselves in life and experience a sense of direction. This process relies, to a large extent, on the temporal structure that haemodialysis affords life; it is by repeatedly undergoing the treatment that patients become able to create a sick body. Even so, many of them find this temporal structure problematic; they experience it as disruptive of their control and future-orientedness and as causing an existentially difficult-to-handle boredom. &lt;br/&gt;&lt;br&gt; The thesis also shows that the political developments and the norms prevalent in the two national contexts studied greatly affect the orientations of the treatment practices and the participants’ lives. In both Riga and Stockholm, ideals of freedom, activity, control, and self-actualisation influence what forms of patienthood and personhood are enacted. &lt;br/&gt;&lt;br&gt; The study indicates that persons who fall ill with a serious and chronic disease only gradually become able to understand and actively cope with their differently embodied circumstances of life. This suggests that medical professionals should not too hastily enlist their patients as experts on their own bodies, but rather provide them with the time and support necessary for making repeated attempts at creating and maintaining a life with a sick body.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Avhandlingen undersöker de två behandlingsalternativ, hemodialys och njurtransplantation, som är tillgängliga för personer med njursvikt. I fokus för undersökningen står de former av person- och patientskap som skapas och upprätthålls i hemodialys- och njurtransplantationsvården samt i de njursjukas vardagsliv. Ett av avhandlingens grundläggande antaganden är att dessa vårdformer och vardagsliv är djupt sammanflätade med de kulturella, historiska, ekonomiska och politiska kontexter inom vilka de försiggår.&lt;br/&gt;&lt;br&gt; Avhandlingen är skriven inom forskningsprojektet Kroppen som gåva, resurs och vara: organtransplantationer i Östersjöområdet, som involverade forskare från Södertörns högskola och Lunds universitet och finansierades av Östersjöstiftelsen. Den bygger på ett etnografiskt material bestående av observationer och djupintervjuer med patienter och vårdgivare på fyra hemodialysavdelningar: en i Riga, Lettland, och tre i Stockholm, Sverige. Det teoretiska och metodologiska angreppssättet är kulturanalytiskt och fenomenologiskt och utgår från en syn på kulturer som föränderliga och relationella och människan som förkroppsligad och djupt sammanflätad med den omgivande världen.&lt;br/&gt;&lt;br&gt; Till skillnad från tidigare humanistisk och samhällsvetenskaplig forskning på området tar avhandlingen ett brett grepp om de fenomen som studeras. Snarare än att endast rikta intresset mot den mest spektakulära av de två behandlingsalternativen, organtransplantation, studeras de njursjukas insjuknande och första möten med de två vårdformerna samt deras erfarenheter av att återvända till hemodialys efter att ha varit transplanterade. &lt;br/&gt;&lt;br&gt; Avhandlingen belyser på så sätt de normer och värderingar som de undersökta medicinska praktikerna är laddade med. Här blir det tydligt att det finns en utbredd syn på hemodialys som undermålig jämfört med transplantation, vilken tenderar att beskrivas som kapabel att, på ett rutinmässigt sätt, återställa de njursjukas hälsa och återföra dem till ett normalt liv. Patienternas berättelser visar dock att sjukdomen ständigt är närvarande även i livet som transplanterad, och att den utlovade normaliteten inte är ett självklart resultat av behandlingen. &lt;br/&gt;&lt;br&gt; Men även hemodialyspraktiken är laddad med inflytelserika normer och värderingar, ur vilka idéer om ett idealt patientskap framträder. Enligt detta på många sätt nyliberalt influerade ideal bör patienter vara autonoma, ansvarstagande, aktiva och kunniga i relation till sjukdomen och behandlingarna. Vårdgivarna bör se dem som experter på sina egna kroppar och som individer med specifika önskningar och behov. För de njursjuka är dessa ideal dock svåra leva upp till, inte minst till en början, när den förändrade kroppsligheten och vardagen är ny. Efter en tid tillägnar de sig dock förmågan att skapa en slags syntes mellan sin kropp som de upplever den och kroppen som den förstås och framställs inom medicinen, en syntes som gör det möjligt för dem att i viss utsträckning omorientera sig i tillvaron och uppleva en slags riktning. Att denna möjlighet uppstår beror till stor del på den tidsliga struktur som hemodialys ger livet. På grund av sin repetitiva natur blir behandlingen till slut i stor utsträckning rutinmässig och därför möjlig att göra till en del av den kroppslighet med vilken man bebor världen. Paradoxalt nog upplever många på samma gång denna tidsliga struktur som problematisk, som något som berövar dem kontrollen över deras liv.&lt;br/&gt;&lt;br&gt; Avhandlingen visar alltså att personer som insjuknar i allvarliga och kroniska sjukdomar endast successivt tillägnar sig förmågan att förstå och aktivt hantera det nya förkroppsligade sätt på vilket de bebor världen. Vårdpersonal bör därför inte från början se på och behandla patienterna som experter på sina kroppar, utan snarare ge dem den tid och stöd de behöver för att göra upprepade försök att skapa och upprätthålla ett liv med en sjuk kropp.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/25b0e656-b605-425f-a5b6-d574ea3ec951</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Gunnarson_Please_be_patient.pdf">https://portal.research.lu.se/files/21809834/Gunnarson_Please_be_patient.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5149679</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund Studies in Arts and Cultural Sciences</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>haemodialysis</topic> <topic>kidney transplantation</topic> <topic>kidney failure</topic> <topic>patienthood</topic> <topic>culture</topic> <topic>phenomenology</topic> <topic>embodiment</topic> <topic>medical practice</topic> <topic>neoliberalism</topic> </subject> <subject authority="lup"> <topic>Cultural Studies</topic> <topic>Philosophy</topic> <topic>Ethnology</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-981458-3-0</identifier> <identifier type="oldLupId">8410361</identifier> <identifier type="Scopus">84991094801</identifier> <part> <extent unit="pages"> <total>435</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>https://www.scopus.com/pages/publications/84991094801</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-01-29T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>25b0e656-b605-425f-a5b6-d574ea3ec951</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T10:51:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-14T09:12:57Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T10:51:24+02:00</recordDateApproved> </recordInfo> </mods>

One easily gets the impression that all these men look more or less identical; the suits seem to resemble uniforms. Furthermore, compared to the women’s clothing of the period, the suit seems restrained and even drab in its shape and colour. The dissertation takes up this point and examines the claim that all men look alike in a suit. The purpose of the dissertation is to study what was signalled when groups as disparate as princes, artists and hod-carriers dressed in similar pieces of clothing. If there were, in fact, differences, of what did they consist; how did the men invest the suit with new and different meanings? This dissertation does not, however, focus exclusively on suits. The three groups of men wore work-specific clothes, as well. How might one interpret the contrasts between their work clothes and civilian attire? The primary source material consists of portraits of men from the three above-mentioned groups. The pictures are supplemented by an examination of some of the clothing actually used by men who belonged to the groups in question. &lt;br/&gt;&lt;br&gt; Research into how princes, artists and hod-carriers dressed showed that these groups moved in different tension fields. These tension fields were created by historic and social problems with which the men had been forced to cope. The princes’ tension field was that of tradition/modernity, the artists’ that of boundary-crossing/conformity and the hod-carriers’ that of body/intellect. The men’s way of dressing, their appearing in both civilian and in work-related clothing, embodied a struggle both for the right to be included in modern society, and for the freedom to remain alien – or rather, for the right to be included on their own terms. The suit was polyseme, capable of denoting several different manly ideals and masculinities. It was a question of who the suit-wearing man was – the collective to which he belonged, as well as his personal style and taste, that determined the suit’s connotation. For this reason, the men&apos;s suits came to signal different things, even when their surface appearance was fairly uniform. However, variations did occur. The men exploited the margins of freedom available within male fashion. When the artists expanded the frames determining how a suit could be worn, they showed that male dress could vary even beyond what the decrees of fashion might allow.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8c9ca40d-36a3-42be-85cf-873182ecfc1c</url> </location> </relatedItem> <originInfo> <publisher>Nordiska museets förlag</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>turn of the century 1900</topic> <topic>hod-carriers</topic> <topic>artists</topic> <topic>princes</topic> <topic>masculinity</topic> <topic>male dress</topic> <topic>fashion</topic> <topic>suits</topic> <topic>Sweden</topic> </subject> <subject authority="lup"> <topic>History</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Södertörn Doctoral dissertations</title> </titleInfo> <identifier type="issn">1652-7399</identifier> <identifier type="isbn">978-91-7108-541-2</identifier> <identifier type="oldLupId">1659211</identifier> <part> <detail type="volume"> <number>48</number> </detail> <extent unit="pages"> <total>156</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-09-17T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>8c9ca40d-36a3-42be-85cf-873182ecfc1c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T10:52:21+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T10:52:21+02:00</recordDateApproved> </recordInfo> </mods>

Literature as a human document, as the footprint of a human being, and its function as a bearer of experiences and insights is at the heart of the characterisation. The title of this dissertation – A man’s expression – illustrates the synthesis between the literary and the human. The subtitle shows that this synthesis is based on Ruin’s autobiographical essays – especially the two autobiographical works, Rummet med de fyra fönstren (1940) [The Room with the Four Windows] and Hem till sommaren (1960) [Home for the Summer]. Chapter 1, “Introduction”, presents and dis-cusses the theoretical bases for the analysis. An important point of departure is the knowledge about interpretations in the hermeneutic tradition. Chapter 1 also introduces the major form of literary expression in Ruin’s writings – the autobiographical essay. In chapter 2, “Hans Ruin’s biography”, I only use external sources in order to paint a more auto-nomous picture of his life. Chapter 3, “The Beautiful and its Transformations”, introduces the essential features of Hans Ruin’s aesthetics. Det skönas förvandlingar (1962) [The Transformations of the Beautiful], which he considered his aesthetic testa-ment, is a natural stepping stone in this context. In chapter 4, “Diary – a source in the literary creation”, Hans Ruin’s diary is introduced, and the major role it played in his writings. The chapter thoroughly examines how Rummet med de fyra fönstren develops. In chapter 5, “On the outskirts of the Finno-Swedish archipelago”, it is time to study what Hans Ruin’s background meant to him. Hans Ruin’s first auto-biographical work Rummet med de fyra fönstren, and thereby also the idyll, is at the centre of chapter 6, “Idyll and Apocalypse”. Bachtin’s idea of “the unity of place” and Ellen Zetzel Lambert’s thoughts on “the pastoral elegy” are important analytical tools here. Chapter 7, “New Light over Härligö”, treats Hans Ruin’s second autobiographical work Hem till sommaren. The light now falling over Härligö is no longer so idyllic. The last chapter, “Conclusion”, binds the various threads of the dissertation together. The role of Härligö as a catalyst for the prose of place which Ruin writes is emphasised, as well as the significance of his Finno-Swedish identity.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; I den första avhandlingen på svenska om den finlandssvenske estetikern, filosofen och författaren Hans Ruin (1891–1980) förenas ett intresse för det litterära uttrycket med ett intresse för människan bakom orden. Litteraturen som mänskligt dokument, som spåret efter en människa, och dess funktion som överbringare av erfarenheter och insikter står i centrum för framställningen. Avhandlingens titel, En människas uttryck, visar på denna syntes mellan litterärt och mänskligt. Avhandlingens undertitel, Studier i Hans Ruins självbiografiska essäistik, visar att det är i Ruins självbiografiska essäistik som den har sin bas, särskilt viktiga är de båda självbiografiska verken Rummet med de fyra fönstren (1940) och Hem till sommaren (1960).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingens första kapitel, ”Inledning”, presenteras och diskuteras de teoretiska utgångspunkterna för undersökningen. En viktig utgångspunkt är den kunskap om tolkningar som finns samlad inom den hermeneutiska traditionen. En annan viktig förutsättning är tilltron till den litterära texten som källa till kunskap om författaren. I det första kapitlet presenteras också den viktigaste litterära uttrycksformen i Ruins författarskap – den självbiografiska essän. Tillsammans med idyllgenren är den självbiografiska essän den viktigaste genren som behandlas i avhandlingen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den främsta kunskapen om Hans Ruins liv har vi genom hans självbiografiska texter. För att ge en mer oberoende bild av hans liv använder jag i det andra kapitlet, ”Hans Ruins biografi”, enbart externa källor.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingens tredje kapitel presenteras grunddragen i Hans Ruins estetik. Boken Det skönas förvandlingar (1962) som han betraktade som sitt estetiska testamente, är här en naturlig utgångspunkt. Två egenskaper står fram som särskilt signifikanta för Ruins estetik: konstens roll som förmedlare av känslor och konsten som en existentiell resurs i livet. Två tidiga lärare och inspiratörer som påverkade Ruins syn på livet och konsten var Hans Larsson och Yrjö Hirn. De får båda en grundlig presentation i kapitlet, med tonvikt på de områden där deras respektive betydelse för Ruin var störst. Ytterligare ett viktigt drag i Hans Ruins estetik är det livslånga intresse han hade för nya konstnärliga uttryck. Han såg hur konsten hela tiden strävade efter att erövra nya områden, och att den konst som inte utvecklades förlorade sin förmåga att engagera. Detta innebär dock inte att han motståndslöst tog in allt det nya. Parallellt med hans intresse för det moderna fanns också en skepsis. Detta visade sig bland annat i hans förhållande tilll den finlandssvenska modernismen – en från början avvaktande inställning byttes efterhand ut mot en större öppenhet mot den nya dikten. Efter emigrationen i Sverige verkade han närmast som en ambassadör för den nya finlandssvenska litteraturen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingens fjärde kapitel, ”Dagboken – en källa i det litterära skapandet”, presenteras Hans Ruins dagbok och den viktiga roll den haft i författarskapet. I kapitlet studeras ingående hur Rummet med de fyra fönstren växer fram. Det är framförallt hans självbiografiska essäistik som har sin bas i dagboken. När han mot slutet av sitt liv publicerade dagboksurvalet Uppbrott och återkomst är det därför lätt att tro att dagboken därigenom var uttömd, men så är det inte. Hans dagbok är nämligen inte enbart en arbetsdagbok utan förtjänar också att studeras för sin egen skull. Den övervägande delen av den har aldrig tidigare publicerats. Bland dessa opublicerade texter finns några av de mest drabbande som Ruin överhuvudtaget har skrivit och som visar upp en mindre känd sida hos honom – tvivlet han hade på sig själv och sin förmåga att skriva.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I kapitlet ”I det finlandssvenska havsbandet” är det så dags att undersöka vad Hans Ruins finlandssvenska bakgrund betytt för honom. Boken Ett land stiger fram kom ut 1941 och visade hur viktig hans finlandssvenska identitet var för honom. I boken skildrar han hur de finlandssvenska författarna tar sitt land i språklig besittning. Boken är i första hand ett finlandssvenskt projekt, men ingår också i den unga nationens kamp för sin självständighet. Skärgården bildar en självklar fond i mycket av det Ruin skrivit, inte minst i Rummet med de fyra fönstren och Hem till sommaren. I kapitlet presenteras också ett antal finlandssvenska författare som skildrar en liknande miljö som Ruin. Det gäller först och främst de tidiga valfrändskaperna Petrus Nordmann och Gustav Alm, men också hans kollegor och vänner Jarl Hemmer och Runar Schildt. Ett särskilt tema, hemlängtan, skärskådas i kapitlets avslutning.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hans Ruins första självbiografiska verk Rummet med de fyra fönstren, och därmed också idyllgenren, står i centrum i kapitlet ”Idyll och apokalyps”. Efter att först ha tecknat en bild av idyllen som litterär genre, placeras Ruins verk in både i en allmän genretradition och i en specifikt finlandssvensk. Bachtins begrepp ”platsens enhet” och Ellen Zetzel Lamberts tankar kring ”den pastorala elegin” är här viktiga analysinstrument. Rummet med de fyra fönstren kom ut 1940, som en påminnelse om de värden som var på väg att förloras. Boken visar vilken betydelse platsen Härligö hade för honom. Kapitlet avslutas med en studie av Et in Arcadia ego-problematiken i Rummet med de fyra fönstren. Även på Härligö finns döden, men idyllen tillhandahåller ett landskap där Ruin kan placera sin sorg över tillvarons förgänglighet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingens sjunde kapitel ”Nytt ljus över Härligö” behandlas Hans Ruins andra självbiografiska verk, Hem till sommaren. Det ljus som nu faller över Härligö är inte längre så idylliskt. Hans Ruin ger en bild av en familj med starka spänningar och inte minst av sin egen kamp för att förena dessa båda världar i sin egen person. I en annan av de självbiografiska essäerna i boken, ”Snålt ljus”, berättar Ruin den tragiska historien om barndomsvännen Alfreds liv och för tidiga bortgång. Essän innehåller trots tragiken ett brett stråk av ljus och hoppfullhet. Detta ljus kommer från en händelse som han flera gånger i sitt författarskap återkom till och som påverkade hela hans livssyn. Ruin får till uppgift att meddela Alfreds föräldrar att deras son ligger för döden. Fadern reagerar på detta bud med att gå ut och visa de äppelträd han är i färd med att ympa. Några dagar senare dör Alfred. ”Snålt ljus” är en berättelse om den lilla människans storhet, en berättelse formad av livet självt. Händelsen var, med ett uttryck lånat från Mikael Enckell, en ”biografisk supernova” i Hans Ruins liv.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I det sista kapitlet, ”Avslutning”, knyts avhandlingens trådar ihop. Härligös roll som katalysator för den platsens prosa som Ruin skriver lyfts fram, liksom den finlandssvenska identitetens betydelse för honom. I Hans Ruins författarskap bryts impulser från många olika håll. Den breda utblicken grundlades tidigt med långa resor och vistelser i Europa och Sydamerika under främst 1930- och 1940-talen. Han kom att spela en viktig roll under dessa år som en av de ihärdigaste försvararna av de humanistiska värdena i Norden. Emigrationen till Sverige medförde att han på nära håll fick ta del av ett svenskt kulturliv, och han blev själv en naturlig del av detta kulturliv. Många av hans viktigaste böcker kom ut under hans tid i Lund. Här förvaras också hans efterlämnade papper, däribland dagboken som är så central för förståelsen av hans författarskap. Idyllen spelar en viktig roll i min framställning och den främsta anledningen till detta är att den också gjorde det för Hans Ruin – både som litterär genre och som livsstrategi. Hans Ruins självbiografiska essäistik är avhandlingens självklara centrum, främst manifesterad i de centrala verken Rummet med de fyra fönstren och Hem till sommaren. Om dessa båda verk har det funnits en hel del att säga, inte minst om deras inbördes komplexa relation, där mörker blir ljus och ljus mörker beroende på var man fäster blicken. Uttrycksdimensionen finns i all konstnärlig verksamhet. Den främsta anledningen till att jag har betonat just denna aspekt i Hans Ruins fall är att uttryckskraften är så stark i hans texter. Han ville förmedla sina erfarenheter och insikter till en bred publik, och han var medveten om vikten av att behärska sina uttrycksmedel – vare sig det gällde att nå fram till bokläsaren, åhöraren i föreläsningssalen eller vid radioapparaten. Hans Ruin är en författare för de många, inte för de få.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0752334c-878a-44bc-b78c-161644f8ff5e</url> </location> </relatedItem> <originInfo> <publisher>Svenska litteratursällskapet i Finland</publisher> <dateIssued encoding="w3cdtf">2003</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>General and comparative literature</topic> <topic>Culture Critic</topic> <topic>Second World War</topic> <topic>pastoral elegy</topic> <topic>unity of place</topic> <topic>apocalypse</topic> <topic>idyll</topic> <topic>Jarl Hemmer</topic> <topic>Arvid Mörne</topic> <topic>diary</topic> <topic>Finno-Swedish modernism</topic> <topic>Yrjö Hirn</topic> <topic>aesthetics</topic> <topic>Hans Larsson</topic> <topic>thematic criticism</topic> <topic>Graham Good</topic> <topic>autobiographical essay</topic> <topic>hermeneutics</topic> <topic>literature criticism</topic> <topic>literary theory</topic> <topic>Allmän och jämförande litteratur</topic> <topic>litteraturkritik</topic> <topic>litteraturteori</topic> <topic>Scandinavian languages and literature</topic> <topic>Nordiska språk (språk och litteratur)</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Skrifter utgivna av svenska litteratursällskapet i Finland</title> </titleInfo> <identifier type="issn">0039-6842</identifier> <identifier type="isbn">951-583-098-2</identifier> <identifier type="oldLupId">21223</identifier> <part> <detail type="volume"> <number>657</number> </detail> <extent unit="pages"> <total>354</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2004-01-17T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>0752334c-878a-44bc-b78c-161644f8ff5e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T11:45:45+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T11:45:45+02:00</recordDateApproved> </recordInfo> </mods>

More specifically, the interest is to determine whether students’ net based dialogues give rise to patterns of dominance/subordination similar to those observed in face-to-face situations. Research focus included an interest in the significance of group composition. The questions posed were whether interaction processes depend on a) certain background characteristics of the students and/or b) are affected by group composition: whether the majority/minority of the group members are male/female; have parents with high or low parental educational attainments; speak Swedish or another language at home; and if they are born in our outside of Sweden. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; From the investigation, involving 147 students in 29 groups, it appears that not only do the individual student&apos;s background characteristics play an important part with respect to communication patterns; the composition of the group with respect to these background characteristics was also found to influence the communication patterns. When the study group was analysed as a whole, older students were found to be more active in the discussion than younger. Students born outside Sweden and students speaking another language than Swedish at home played a more secluded part in the discussion than students with a Swedish background. When group composition was included in the analysis, it was found that the presence of more males in a group seemed to influence women’s contributions negatively. Female students sent fewer postings and fewer words in total the higher the share of males in the group. The discussion style was also affected; more agreements and supportive remarks were made in groups that had a higher the share of males. In groups with a larger proportion of students who were born in Sweden and in groups with a high share of students speaking Swedish at home, more but shorter contributions were posted. The group composition with respect to students with a Swedish background was also found to affect the use of disagreements; in groups with a high share of students born in Sweden or speaking Swedish at home, fewer disagreement remarks were sent than in groups with a lower share of this category of students.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6b408abd-3fb6-4a83-b7ce-3684661cc5f3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Annette_Johnsson.pdf">https://portal.research.lu.se/files/2670122/1397380.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1069222</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Holmbergs</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>minority</topic> <topic>cultural background</topic> <topic>sex</topic> <topic>ethnicity</topic> <topic>gender</topic> <topic>age</topic> <topic>socio-economic</topic> <topic>dialogicity</topic> <topic>web based</topic> <topic>computer based</topic> <topic>CMC</topic> <topic>net based</topic> <topic>asynchronous</topic> <topic>CSCL</topic> <topic>teacher education</topic> <topic>power structures</topic> <topic>dialogues</topic> <topic>Group work</topic> <topic>team work</topic> <topic>symbolic capital</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> <topic>Educational Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Malmö Studies in Educational Sciences</title> </titleInfo> <identifier type="issn">1651-4513</identifier> <identifier type="isbn">978-91-977100-9-1</identifier> <identifier type="oldLupId">1397378</identifier> <part> <extent unit="pages"> <total>196</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-09-04T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>6b408abd-3fb6-4a83-b7ce-3684661cc5f3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T11:51:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T11:51:00+02:00</recordDateApproved> </recordInfo> </mods>

Health-Related Quality of Life (HRQoL) questionnaires are increasingly used. The objective of this thesis was the evaluation of HRQoL measures before and after lumbar spine surgery, and their relation to other evaluation parameters as well as relevance of differences.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The patients included were operated on for lumbar spine disorders at the Lund University, Department of Orthopedics and included in the Swedish National Lumbar Spine Registry. Baseline (before surgery) data include age, sex, smoking habits, duration of preoperative back and leg pain as well as sick leave, number of previous operations, and working status. Pre- and postoperatively VAS pain scores and the SF-36 questionnaire on HRQoL are registered as well as analgesic intake, walking distance and at follow-up change in leg and back pain as well as patient satisfaction.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The number of proposed outcome instruments is too high and a consensus on best HRQoL is required. The data collection protocol of the Swedish National Lumbar Spine Registry can reliably detect postoperative improvements between large groups of patients. Pain intensity measured on the VAS scale correlates significantly to other indicators of perceived pain. HRQoL as measured by SF-36 showed a pronounced reduction compared to healthy and LBP population preoperatively. One year after surgery improvement in all domains of the SF-36 except general health was seen. The global effect of lumbar spine surgery in the sample is similar to effect sizes of other successful orthopaedic interventions. The use of standardized outcome measures allows international comparisons, although caution should be used in the interpretation of differences.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Hur man värderar resultat av kirurgisk behandling av ländryggens degenerativa åkommor är ett stort, komplext och delvis kontroversiellt ämne. Denna avhandling studerar resultatvärdering med olika metoder och instrument, huvudsakligen baserat på resultat från det nationella svenska ländryggskirurgiregistret.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete I. Inventering av befintliga instrument i litteraturen avseende hälsorelaterad livskvalitet vid ryggsjukdom. Nittiotvå frågeinstrument kunde identifieras, mer än hälften publicerade för första gången under de senaste 10 åren. Internationell enighet om lämpliga utvärderingsinstrument behövs, inte ytterligare nykonstruerade utvärderingsinstrument.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete II. Validering av data från svenska ryggregisterprotokollet. Test-retest analys av 119 patienter, 63 av dessa fyllde i det preoperativa protokollet två gånger och 59 andra patienter fyllde i det ett år postoperativa protokollet två gånger. Reliabilitetsanalyser gjordes relaterade till tidsintervallet mellan första och andra ifyllande. Reliabiliteten minskade om intervallet översteg 3 veckor i den preoperativa gruppen och 9 veckor i den postoperativa gruppen. Protokollet har förmåga att dokumentera resultatförändringar efter kirurgi.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete III. Smärtmätning på VAS-skala före och efter kirurgisk behandling och korrelation mellan olika former att mäta smärtlindring utfördes på 755 konsekutiva patienter. Smärtprofilerna klart särskilda mellan de olika sjukdomsdiagnoserna, snabb regress postoperativt för medelvärden för VAS-smärta såväl avseende rygg- som bensmärta. Signifikanta korrelationer mellan patienttillfredsställelse av kirurgi och andra ?smärtfacit? såsom upplevd förändring i smärta, VAS-smärta vid uppföljning samt analgeticakonsumtion.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete IV. Livskvalitetsmätning med SF-36 på 451 patienter planerade för ländryggskirurgisk åtgärd. Normativa data för dessa sjukdomsgrupper etablerades och visade mycket låga värden på SF-36 profilerna jämfört med friska människor i samma ålderskategori, inte bara beträffande fysiska utan även psykiska domäner. Likaså visade den aktuella sjukdomsgruppen sämre livskvalitet än patienter med fibromyalgi, rheumatoid artrit, migrän och ytterligare några andra sjukdomar. Ett stort basmaterial som norm för framtida studier har presenterats.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete V. SF-36 såsom resultatutvärderande instrument efter ryggkirurgi evaluerades. Trehundrafemtioen patienter fyllde i SF-36 formuläret preoperativt och 1 år postoperativt. Korrelation mellan SF-36 domäner och andra resultatparametrar studerades. Stark korrelation mellan minskad kroppslig smärta i SF-36 och minskad smärta på VAS-skalan sågs, likaså korrelerade fysisk funktion starkt till förbättring i gångfunktionen. En clusteranalys kunde skilja patienter med förmåga till emotionell adaption från patienter med mera dysfunktionellt beteende, förstnämnda gruppen med låga fysiska och ganska normala mentala domäner, sistnämnda gruppen med uttalad reduktion i båda aspekterna. Postoperativt förbättrades båda patientkategorierna i stort sett i samma omfattning.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete VI. Möjligheten att jämföra SF-36 profiler i två olika patientmaterial i olika länder med samma diagnos studerades. Nittio patienter i en FDA-studie av amerikanska patienter opererade för spinal stenos med en ny operationsteknik, indirekt dekompression i lokalanestesi, jämfördes med 90 ålders- och könsmatchade patienter, opererade för spinal stenos vid ortopediska kliniken i Lund på konventionellt vis med dekompressionsoperation. Livskvalitetsprofilerna matchades till nationsspecifika ålders- och könsnormerade data. Patientselektionen inte likartad i grupperna men möjligheten att med gemensamma resultatparametrar kunna jämföra olika patientmaterial påvisades och kommer att kunna användas i framtiden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har denna avhandling skapat referensbanker för framtida studier av ländryggskirurgi och presenterat en analys av olika resultatutvärderingsparametrar och deras inbördes relation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/735acc0b-8de0-4317-8bc6-df391e3383c5</url> </location> </relatedItem> <originInfo> <publisher>Department of Orthopaedics, Lund University</publisher> <dateIssued encoding="w3cdtf">2005</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>traumatologi</topic> <topic>Surgery</topic> <topic>Skeleton</topic> <topic>muscle system</topic> <topic>rheumatology locomotion</topic> <topic>Skelett</topic> <topic>muskelsystem</topic> <topic>reumatologi</topic> <topic>Spinal stenosis</topic> <topic>Disc</topic> <topic>Questionnaire</topic> <topic>Outcome assessment</topic> <topic>Lumbar spine</topic> <topic>Kirurgi</topic> <topic>traumatology</topic> <topic>orthopaedics</topic> <topic>ortopedi</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Acta Orthopaedica.

It also examines the interrelationships of different scientific disciplines dealing with urban travel. The main conclusions relate to the scientific concept of habit. This concept and the associated behaviours are not well-studied in the social and cultural sciences. Indeed, in some contexts the concept is bereft of meaning, e.g. when the notion of travel habits is used to represent the travel patterns of an entire population. This study demonstrated the (traffic and environmental policy) significance of non-habitual travel, but also showed habitual travel to have inherent resistance to change, i.e. with habits acting as a buffer between experience and response. Case studies revealed travel habits to be a cultural phenomenon, since acceptable travel habits are expressed in a restricted local and social context. People develop their (travel) habits in mutual and only partly conscious interactions with each other and their material surroundings. The case studies also showed how changes occurring during critical points in the course of a life (primarily as regards housing, employment and household composition) brought about particularly clear changes in individual travel habits. Stability and sustainability in urban travel patterns could be achieved through the promotion and gradual spread (geographical, between age classes, etc.) of certain types of travel habits that are already in use at the individual level. Thus habits should be regarded less as an obstacle and more as an opportunity for sustainable development.&lt;br/&gt;&lt;br&gt; A case study of the Stockholm congestion charge trial showed wide variation and ingenuity in how Stockholmers dealt with this new feature of their daily lives. For example, many stopped many stopped driving into the charging zone in order to demonstrate, to themselves and others, their disagreement with the charge and the political circumstances surrounding its introduction. Interestingly (and paradoxically), this probably contributed to the overall major reduction in traffic, perceived at a societal level as evidence of the success of congestion charging. However, regarding the scope for sustainable development of urban travel, the conclusion from this appraisal of the Stockholm trial was that environmental, congestion-reducing and possibly traffic-controlling political measures appear to be in public demand.&lt;br/&gt;&lt;br&gt; Efforts in this thesis to interrelate the scientific perspectives of the different disciplines studying the various levels of urban travel (e.g. sociology, human geography and ethnology in relation to transport economics and psychology) indicated that further collaboration is required. As with the concept of travel habits, there are numerous concepts that could benefit from being developed and tested through interdisciplinary collaboration.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Avhandlingen belyser vad resvanor är, hur storskaliga trafikreglerande åtgärder tas emot samt hur storstadsbornas resmönster kan bli miljömässigt hållbara på lång sikt. Jag diskuterar dessutom problem och möjligheter i skärningsområden mellan olika vetenskapliga discipliner som griper sig an dessa frågor.&lt;br/&gt;&lt;br&gt; De viktigaste slutsatserna gäller för det första det vetenskapliga begreppet vana. Varken begreppet eller företeelsen i sig är särskilt väl undersökt i samhälls- och kulturvetenskaperna. Begreppet töms i vissa sammanhang på sitt innehåll, t ex när resvanor används som en beteckning på en befolknings hela resmönster. Mina studier har pekat på (den trafik- och miljöpolitiska) betydelsen av resor som inte är vanemässiga, men också på att vanemässiga resor har en trögföränderlighet som kan beskrivas som en buffert mellan erfarenhet och respons. Resvanor och färdmedelsval exemplifierar dessutom hur vanor är ett kulturellt fenomen eftersom det förgivettagna i resvanorna – ”så här gör man” – förmedlas i avgränsade lokala och sociala sammanhang. Människor skapar sina vanor i ett ömsesidigt och bara delvis uppmärksammat samspel med varandra och med sin materiella omgivning. Jag har också visat hur förändring under brytpunkter i levnadsloppet (främst avseende boende, sysselsättning och hushållssammansättning) kan innebära särskilt tydlig förändring av individuella resvanor.&lt;br/&gt;&lt;br&gt; För det andra har mitt studium av Stockholmsförsöket visat på stor variation och uppfinningsrikedom i hur Stockholms invånare hanterade det nya inslag i vardagslivet som trängselskatten innebar. Många lät exempelvis bli att köra bil med motivet att, inför sig själva och andra, symbolisk ta avstånd från avgifterna samt även från de politiska omständigheterna kring införandet av dessa. Detta bidrog intressant (och paradoxalt) nog till den stora trafikminskning som på en samhällelig nivå uppfattades som ett framgångsbevis för trängselskatten. När det gäller möjligheter till hållbar utveckling av resandet i storstaden är dock slutsatsen av studiet av stockholmsförsöket att miljöförbättrande, trängselminskande och i någon mån även trafikstyrande politiska åtgärder verkar efterfrågas av invånarna. Dessutom menar jag att vanor i mindre grad bör uppmärksammas som hinder och i högre grad som förutsättningar för hållbar utveckling. Stabilitet och långsiktighet i storstadens resmönster kan uppnås genom succesiv spridning (geografiskt, mellan åldersklasser o.s.v.) och upprätthållande av några olika slags resvanor som redan idag går att återfinna på en individuell nivå.&lt;br/&gt;&lt;br&gt; Slutligen har arbetet med att relatera ett antal vetenskapliga perspektiv till varandra utmynnat i att ytterligare samarbete verkar krävas mellan de vetenskaper som tagit som sin uppgift att studera olika nivåer av resandet i storstaden. Detta gäller bl.a. sociologi, kulturgeografi och etnologi i förhållande till transport- och samhällsekonomi samt psykologi. Ett flertal begrepp kan i likhet med begreppet resvanor behöva utvecklas genom att prövas i samarbete mellan disciplinerna.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4a7dd8da-ab6a-4452-ae4c-edf72bc061bb</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="greger.pdf">https://portal.research.lu.se/files/2818225/1257545.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1749440</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Avdelningen för miljöstrategisk analys – fms, KTH, Drottning Kristinas väg 30, SE-100 44 Stockholm</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>climate change</topic> <topic>Travel habits</topic> <topic>Stockholm county</topic> <topic>traffic policy</topic> <topic>environmental aspects</topic> <topic>city of Stockholm</topic> <topic>interdisciplinary research</topic> <topic>congestion charging</topic> <topic>the Stockholm trial</topic> <topic>policy instruments</topic> <topic>habits</topic> <topic>mobility</topic> <topic>urban transport</topic> <topic>actor network theory</topic> </subject> <subject authority="lup"> <topic>Ethnology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>TRITA-INFRA-FMS 2008:5, TRITA-SUS 2008:2</title> </titleInfo> <identifier type="issn">1654-479X</identifier> <identifier type="isbn">978-91-628-7611-1</identifier> <identifier type="oldLupId">1230062</identifier> <part> <extent unit="pages"> <total>193</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-24T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>4a7dd8da-ab6a-4452-ae4c-edf72bc061bb</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:11:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:11:11+02:00</recordDateApproved> </recordInfo> </mods>

In order to provide increased access to the labour market for people with disabilities all three studies countries have undertaken more of less far-reaching legislative measures over a number of decades, both in line with, or as a result of, general labour and employment legislation, but also as more specific parts of the labour market regulation. Obviously legislators in all three countries, and more recently in the European Union, have realised that access to the labour market is a vital and important part of societal inclusion and participation.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The study provides a legal dogmatic and comparative analysis of the field of law and raises questions about how rights are provided to individuals under these laws in the different national settings and in what way the legislation represents or reproduces different normative patterns.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Three different legal areas appear all over the dissertation, these are positive measures, employment protection and discrimination law. Legislation on positive measures, such as quota-legislation and regulations on supported or sheltered employment, vary widely between the countries, as do employment protection legislation, while the disability discrimination legislation in the different countries is turning into a more EC-conform shape in line with recent EC-legislation on discrimination.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Arbete är centralt i det moderna samhället. Samtidigt står många människor av olika anledningar utanför den ordinarie arbetsmarknaden. Att detta i särskild utsträckning gäller personer med funktionshinder har i många länder fått till följd att lagstiftning antagits för att på olika sätt öka arbetskraftsdeltagandet för denna grupp. De bestämmelser som reglerar arbete och funktionshinder spänner över områden som aktiva arbetsmarknadsåtgärder, anställningsskydd och diskrimineringslagstiftning. I denna bok behandlas utformning och tillämpning av dessa regler i svensk, engelsk och tysk rätt och även EU-rättens förbud mot diskriminering i arbetslivet av personer med funktionshinder.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Boken innehåller rättsdogmatiska och komparativa analyser av regler kring aktiva åtgärder som till exempel kvotering och skyddade anställningar och kring anställningsskydd och diskriminering. Bland annat analyseras hur funktionshinder definieras och hur definitioner påverkar användningen av olika regelsystem. Dessutom undersöks hur rättsreglerna ger uttryck för spänningar mellan olika intressen, normativa grundmönster, och hur korrelationen mellan rättigheter och skyldigheter kommer till uttryck i de undersökta rättsreglerna.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/96e5acf5-99b5-4574-96c5-ac3528f6a5e8</url> </location> </relatedItem> <originInfo> <publisher>Juristförlaget i Lund</publisher> <dateIssued encoding="w3cdtf">2007</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Swedish law</topic> <topic>English law</topic> <topic>German law</topic> <topic>EC law</topic> <topic>disability</topic> <topic>discrimination</topic> <topic>&apos;employment protection&apos;</topic> <topic>integration</topic> <topic>positive measures</topic> <topic>quota</topic> <topic>labour market</topic> <topic>dismissal</topic> <topic>supported employment</topic> <topic>social dimension</topic> <topic>human rights</topic> <topic>mänskliga rättigheter</topic> <topic>comparative law</topic> <topic>komparativ rätt</topic> <topic>private law</topic> <topic>social law</topic> <topic>civilrätt</topic> <topic>socialrätt</topic> <topic>labour law</topic> <topic>arbetsrätt</topic> <topic>EU law</topic> <topic>EU-rätt</topic> </subject> <subject authority="lup"> <topic>Law</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-544-0358-5</identifier> <identifier type="oldLupId">26981</identifier> <part> <extent unit="pages"> <total>447</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2007-02-23T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>96e5acf5-99b5-4574-96c5-ac3528f6a5e8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:21:48+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:21:48+02:00</recordDateApproved> </recordInfo> </mods>

The ongoing flexibilisation of working life is often described as an increase in adaptability and allocative flexibility, and as a shift from traditional to atypical employment. The aim of functional flexibility, which is the main focus of this study, is to vary the content of work in relation to the changing demands of production. In order to achieve functional flexibility the employer can broaden job descriptions and the obligation to work in general, and invest in training and education. This study provides a legal dogmatic and comparative description and analysis of questions regarding the employer’s right to direct and allocate work (including the employer’s right to transfer employees and assign them new and different tasks), the industrial relations model and rules regarding information, consultation and co-determination, the employee’s obligation to work and the employer’s possibilities to achieve a variation in the employee’s obligation to work. Furthermore, the development towards a more general requirement for objective grounds with regard to decision-making in the area of the direction and allocation of work is discussed. The research approach is wide and multidisciplinary, and the aim of the study is to analyse the development and functionality of the law in relation to the flexibilisation of working life.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Detta arbete behandlar regleringen av arbetsgivarens arbetsledningsrätt och arbetstagarens arbetsskyldighet i svensk, engelsk och tysk rätt i ljuset av arbetslivets ökade flexibilisering. Arbetslivets flexibilisering handlar om att öka anpassningsförmågan och rörligheten, och beskrivs ofta som övergången från den traditionella anställningen till atypiska anställningar. Företeelser som ökad globalisering, internationalisering, ny teknologi och framväxten av kunskapssamhället bildar bakgrunden för denna flexibiliseringsprocess. I fokus för avhandlingen står kvalitativ flexibilitet, dvs. flexibilitet inom ramen för en bestående anställning. Kvalitativ flexibilitet handlar om att variera användningen av arbetstagarna och deras arbetsuppgifter i takt med verksamhetens skiftande utseende och behov. Arbetet innehåller en komparativ och rättslig analys av arbetsgivarens arbetsledningsrätt, arbetstagarens arbetsskyldighet och omreglering av arbetsskyldigheten. I framställningen behandlas också arbetsledningsrättens framtida utveckling, och då särskilt frågan huruvida utvecklingen går mot ett mer allmänt krav på saklig grund för arbetsledningsbeslut. Angreppssättet är brett och tvärdisciplinärt, och arbetet syftar till en analys av rättens utveckling och funktionalitet i förhållande till arbetslivets flexibilisering.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e8744f96-1673-4272-8467-fb5ca34bf697</url> </location> </relatedItem> <originInfo> <publisher>Juristförlaget i Lund</publisher> <dateIssued encoding="w3cdtf">2004</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>komparativ rätt</topic> <topic>functional flexibility</topic> <topic>labour market flexibility</topic> <topic>employment contract</topic> <topic>information and consultation</topic> <topic>employment protection</topic> <topic>obligation to work</topic> <topic>variation of contract</topic> <topic>direct and allocate work</topic> <topic>managerial prerogative</topic> <topic>industrial relations</topic> <topic>EC law</topic> <topic>German law</topic> <topic>English law</topic> <topic>labour law</topic> <topic>Swedish law</topic> <topic>comparative law</topic> <topic>Arbetsrätt</topic> <topic>European law</topic> <topic>EU-rätt</topic> <topic>EU law</topic> <topic>public law</topic> <topic>civilrätt</topic> </subject> <subject authority="lup"> <topic>Law</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Skrifter utgivna vid Juridiska fakulteten i Lund; Norma - Normative Development within the Social Dimension</title> </titleInfo> <identifier type="issn">1402-4276</identifier> <identifier type="isbn">91-544-2671-5</identifier> <identifier type="oldLupId">21881</identifier> <part> <extent unit="pages"> <total>432</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2004-10-30T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>e8744f96-1673-4272-8467-fb5ca34bf697</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:26:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:26:31+02:00</recordDateApproved> </recordInfo> </mods>

The study is based on an analysis of osteological remains from sites in Scania, Sweden, dating from the Late Maglemose Culture to the Early Ertebølle Culture.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Tooth development and tooth wear in recent populations from Poland, Germany and Sweden have been studied in order to evaluate and improve the methodology for ageing remains of wild boar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The taphonomic history of bone assemblages has been studied by analysis of the relationship between skeletal part frequencies and bone density and of utility index, bone fragmentation, cut marks, marrow fracturing, carnivore gnawing and spatial distribution.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Osteometric analysis shows that the body size of wild boar during the Atlantic does not decrease, as has been shown for red deer and roe deer. The large body size indicates favourable environmental conditions for wild boar during the Atlantic in South Scandinavia.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Analysis of age and sex profiles reveals two hunting strategies for wild boar. At the sites Ageröd I:HC and Bredasten the prey selection of adults and females indicates a harvest that optimises the short-term return rates and the use of selective hunting methods. The age profiles from Ringsjöholm and Tågerup consist mainly of juveniles and reveal harvesting that reflects the population structure of wild boar; this is the result of unselective hunting methods, such as communal drives.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Estimation of season of death indicates that hunting of wild boar seems to have been concentrated in summer and autumn, while red deer was mainly hunted in late autumn and early winter.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hunting pressure during the Mesolithic in South Scandinavia seems to have been relatively high, affecting the wild game populations, as indicated by age profiles and decreasing abundance of taxa in faunal remains. The impact depletion of wild game had on Mesolithic society and the social, ideological and symbolic importance of hunting, consumption of meat and wild game animals during the Mesolithic is also discussed.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5ed5fcfe-f4db-4b90-941e-4fe22622844e</url> </location> </relatedItem> <originInfo> <publisher>Department of Archaeology and Ancient History, Lund University</publisher> <dateIssued encoding="w3cdtf">2006</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Humanities</topic> <topic>Mesolithic</topic> <topic>body size</topic> <topic>age estimation</topic> <topic>taphonomy</topic> <topic>hunting</topic> <topic>osteology</topic> <topic>Humaniora</topic> <topic>wild boar</topic> </subject> <subject authority="lup"> <topic>History and Archaeology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Acta Archaeologica Lundensia.

Although a rare disease, it is the most lethal gynecologic malignancy. Unspecific symptoms result in late diagnosis and a generally poor prognosis. However, ovarian cancer is a heterogeneous disease comprising different disease entities, which is of importance in clinical decision-making as well as in research. This thesis describes explorative approaches to investigate the ovarian cancer heterogeneity in a hereditary ovarian cancer subset and in histopathological and molecular subtypes of ovarian cancer.&lt;br/&gt;&lt;br&gt; In study I, a gene expression profile differentiating the rare subgroup of Lynch syndrome-associated ovarian cancer from a matched sporadic cohort was identified. The Lynch syndrome-related expression profile was associated with proliferation and cell death processes. An external dataset was used to refine the gene expression profile, but validation with immunohistochemical staining of key proteins did not reveal any differences between the hereditary and sporadic cases. A distinct cluster of hereditary serous and endometrioid cancers was seen, whereas clear cell carcinomas (OCCCs) clustered together, whether hereditary or sporadic. In study II, gene expression profiling of OCCCs revealed extensive inter-tumor heterogeneity. Targeted deep sequencing of 60 cancer-related genes in an OCCC cohort revealed frequent mutations of chromatin remodeling genes, including mutations not previously reported in ovarian cancer. These results remain to be validated.&lt;br/&gt;&lt;br&gt; Study III outlined gene expression profiles in malignant, borderline, and benign serous ovarian tumors. Pre-defined molecular subtypes of ovarian cancer as well as intrinsic breast cancer subtypes were applied to our cohort. Associations between the most aggressive ovarian cancer subtypes and the basal-like breast cancer subtype were identified. The results were validated using a large, external dataset. Furthermore, associations between borderline ovarian tumors and the luminal A breast cancer subtype were discovered. The luminal A breast cancer subtype characterizes hormone receptor positive breast cancer. In study IV, we therefore outlined the protein expression of estrogen receptor (ER) α, ERβ, the progesterone receptor (PR), and the androgen receptor (AR) as well as the prognostic effect of receptor expression in serous and endometrioid ovarian cancer. Expression of PR and AR was associated with a favorable prognosis, and co-expression of PR and AR conferred an additional prognostic benefit. The mRNA levels of the encoding genes were investigated in the molecular subtypes of ovarian cancer using an external dataset. The expression varied between the different subtypes, but no prognostic benefit of dual high PGR and AR levels were revealed.&lt;br/&gt;&lt;br&gt; In conclusion these studies further characterize the ovarian cancer heterogeneity, and support that future ovarian cancer studies need to be stratified for both histopathologic subtypes and molecular features</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Varje år drabbas cirka 700 kvinnor i Sverige av äggstockscancer. Det motsvarar två fulla X2000-tåg. Bara ett av dessa tåg med äggstockspatienter kommer att nå sitt mål - bot. Äggstockscancer är en ovanlig sjukdom och risken att drabbas är liten (jämfört med t.ex. bröstcancer, som fyller hela 22 tåg i Sverige), men prognosen är dyster. Färre än hälften av dem som får diagnosen äggstockscancer är i livet fem år senare. Få eller diffusa symptom, som inte uppenbart signalerar allvarlig sjukdom, leder ofta till sen diagnos då sjukdomen redan hunnit sprida sig. Operation och cytostatika (cellgifter) botar en del, men majoriteten drabbas av återfall i sjukdomen inom två år.&lt;br/&gt;&lt;br&gt; Trots detta är bilden inte nattsvart. Mycket talar för att äggstockscancer är flera liknande sjukdomar snarare än en enda. Det kan förklara varför vissa patienter botas, medan andra får återfall. En del skillnader mellan de olika äggstockscancerformerna är välkända, som histologiska subtyper (cellutseendet i mikroskop), muterade (förändrade) gener samt ärftliga former av äggstockscancer. Mutationer orsakar cancertumörer, men gör också tumörerna sårbara så att de kan behandlas med olika läkemedel. Forskningen kring äggstockscancer tar alltmer hänsyn till skillnaderna som beskrivs här, t.ex. i studier på nya läkemedel, men många frågor återstår att lösa. I den här avhandlingen ingår fyra delarbeten som studerar olika former av äggstockscancer och undersöker hur de kan behandlas.&lt;br/&gt;&lt;br&gt; I studie I användes metoden genexpressionsprofilering för att analysera aktiva (påslagna) gener i ärftlig äggstockscancer kopplad till Lynch syndrom. Lynch syndrom medför en ökad risk att drabbas av flera olika cancersjukdomar. Genaktiviteten i 24 ärftliga äggstockstumörer skilde sig markant från genaktiviteten i 24 icke-ärftliga tumörer. När vi studerade genaktiviteten i de olika histologiska subtyperna fann vi att genaktiviteten i ärftlig äggstockscancer av serös och endometrioid histologisk typ skilde sig mycket från genaktiviteten i icke-ärftlig serös och endometrioid äggstockcancer. Äggstockscancer av klarcellstyp hade däremot liknande genaktivitet vare sig den var ärftlig eller icke-ärftlig. Vi analyserade också tre viktiga proteiner, p-mTOR, EGFR och PTEN, som kunde kopplas till de ärftliga tumörerna. Proteinerna studerades med immunhistokemi (antikroppsfärgning av proteinerna) i mikroskop. Proteinuttrycket skilde sig dock inte mellan de ärftliga och de icke-ärftliga tumörerna. &lt;br/&gt;&lt;br&gt; Äggstockscancer av klarcellshistologi är ovanlig och cytostatika har ofta dålig effekt. I studie II genomförde vi genexpressionsprofilering av 15 klarcellstumörer och fann mycket varierande genaktivitet i tumörerna, trots att de föreföll väldigt lika i studie I. Tio klarcellstumörer analyserades därför med en mutationsanalys som kallas djupsekvensering. Vi noterade att flera gener som är inblandade i hur cellernas arvsmassa (DNA) kontrolleras och läses av till proteiner var muterade. Generna kallas kromatinreglerande och flera av dem verkar vara känsliga för olika läkemedel. Dessa resultat behöver dock analyseras ytterligare.&lt;br/&gt;&lt;br&gt; Den vanligaste formen av äggstockscancer är av serös histologi och har likheter - bl.a. speciella genmutationer - med aggressiv bröstcancer som kallas basal-lik. Indelning av cancerformer baserad på bl.a. genmutationer kallas molekylär subtypning. Sådan indelning används ofta för bröstcancer, men än så länge sällan för äggstockscancer. I studie III analyserades 59 serösa äggstockstumörer med genexpressionsprofilering och delades in i olika molekylära subtyper, både för bröstcancer och för äggstockscancer. Vi jämförde subtyperna och noterade likheter mellan de aggressiva äggstockscancerformerna och den basal-lika bröstcancergruppen. Vi fann också likheter mellan en form av äggstockstumör som kallas borderline (som kan omvandlas till aggressiv äggstockscancer) och hormonberoende bröstcancer. Detta bekräftades i ett annat, större material bestående av 285 tumörer.&lt;br/&gt;&lt;br&gt; I studie IV studerade vi hormonreceptorer med immunhistokemi i 118 serösa och endometrioida äggstockstumörer. Hormonreceptorer är proteiner på tumör-cellernas yta och de styr bl.a. vilka gener som översätts till vilka proteiner i cellen. Receptorerna kan blockeras med s.k. antihormonella läkemedel. Vi studerade två olika östrogenreceptorer (ERα och ERβ), progesteronreceptorn (PR) samt androgenreceptorn (AR). Fler av patienterna vars tumörer hade många PR eller AR levde efter fem år jämfört med dem som hade få PR eller AR. De vars tumörer som hade både många PR och många AR hade ännu bättre prognos, vilket är ett helt nytt fynd. Därefter undersöktes hormonreceptorgenerna i de olika molekylära subtyperna av äggstockscancer i materialet med 285 tumörer. Genaktiviteten varierade mellan subtyperna, men vi fann inga tydliga bevis för att hög aktivitet av PR- och AR-generna kunde kopplas till en bättre prognos. Resultaten i studie III-IV kan tyda på att antihormonella läkemedel möjligen kan vara effektiva mot vissa former av äggstockscancer, men det behöver studeras vidare.&lt;br/&gt;&lt;br&gt; Sammantaget visar de här fyra studierna att det är nödvändigt att gruppera äggstockscancer för att kunna ta hänsyn till alla skillnader, även mellan tillsynes liknande tumörer inom samma histologiska subtyp. Det kan göra det enklare att identifiera vilka tumörtyper som bör få vilka behandlingar och öka sannolikheten att båda tågen når sitt mål – att fler kvinnor med äggstockscancer blir botade.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c05ffd3d-737a-4ee5-9e08-2373bc243e23</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappan_till_tryckning_JJ.pdf">https://portal.research.lu.se/files/3008585/8499981.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1564707</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Oncology and Pathology, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>ovarian cancer</topic> <topic>gene expression profiling</topic> <topic>Lynch syndrome</topic> <topic>targeted deep sequencing</topic> <topic>chromatin remodeling</topic> <topic>molecular subtypes</topic> <topic>endocrine receptors</topic> <topic>prognostic factors</topic> <topic>tumor heterogeneity</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-230-6</identifier> <identifier type="oldLupId">8499980</identifier> <part> <detail type="volume"> <number>2016:5</number> </detail> <extent unit="pages"> <total>111</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-01-29T10:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>c05ffd3d-737a-4ee5-9e08-2373bc243e23</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:50:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:50:24+02:00</recordDateApproved> </recordInfo> </mods>

AAA has a complex etiology involving inflammation, proteolysis, fibrinolysis and coagulation. The general aim of the present thesis was to study the associations between markers of inflammation, proteolysis, fibrinolysis and coagulation with aneurysm size and growth.&lt;br/&gt;&lt;br&gt; In paper I associations between markers for these mechanisms and AAA size were evaluated. Patients with AAA had significantly increased levels of several markers ([endothelin] ET-1, [interleukin] IL-6, [tumour necrosis factor] TNF-α, APC-PCI) compared to age matched healthy controls. Correlations existed between aneurysm size, decreased platelet count, increased high sensitive-C-reactive protein, IL-6 and APC-PCI complex levels.&lt;br/&gt;&lt;br&gt; In paper II effects of statin treatment were investigated, showing that patients on statins had lower levels of cholesterol, but also of homocysteine, ceruloplasmin, orosomucoid, (matrix metallo-proteinase) MMP-9 and ET-1 in plasma, but higher levels of albumin, and the APC-PCI complex.&lt;br/&gt;&lt;br&gt; In paper III relationships between markers of proteolysis, fibrinolysis and coagulation and aneurysm size and growth during follow-up were studied. MMP-2 levels were lower in AAA patients than in healthy controls. Only MMP-2 was related to AAA size.&lt;br/&gt;&lt;br&gt; In paper IV relationships between markers of inflammation and endothelial function and aneurysm growth were studied. We confirmed that initial aneurysm diameter is related to yearly AAA growth. Furthermore, age and initial levels of ET-1 were also related to AAA growth during 7 years follow-up.&lt;br/&gt;&lt;br&gt; In paper V patterns of systemic biomarkers and their relationship to aneurysm growth during yearly follow-up of patients with AAA were analyzed. Few relationships were demonstrated between the development of mediators and aneurysm growth during annual analysis of this patient material, which was extended compared to the previous analyses.&lt;br/&gt;&lt;br&gt; In conclusion, none of the above biomarkers can predict aneurysm growth or replace ultrasound surveillance.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Systemiska biomarkörer hos patienter med aortaaneurysm.&lt;br/&gt;&lt;br&gt; Kroppspulsådern eller aorta är huvudstammen som för syrerikt blod från hjärtat till perifera delar av kroppen. Kroppspulsåderbråck (aneurysm) i buken kännetecknas av försvagning i kärlväggen som i sin tur leder till vidgning av kroppspulsådern. Aneurysm är fyra gånger vanligare hos män än hos kvinnor över 65 års ålder (4:1) och förekommer hos 3-6% av befolkningen i denna ålder. Riskfaktorer för utveckling av aneurysm är ärftlig benägenhet, högt blodtryck, rökning, hjärtsjukdom och vissa lungsjukdomar. Förändringar i kärlväggens bindväv och det höga blodflödet som finns i aorta kan orsaka kärlvidgning och aneurysmutveckling. Aortaaneurysm i buken kan växa med tiden, men orsaken till denna tillväxt är okänd. Vid tillväxt ökar risken för att aneurysmet brister. Bristningen orsakar en livshotande blödning i buken, vilken omedelbart leder till döden för minst 50 % av de drabbade om de inte kommer till vård. Aortaaneurysm kan avbildas med hjälp av ultraljud och datortomografi. &lt;br/&gt;&lt;br&gt; Om man skulle kunna hitta bra metoder för att i blodprov påvisa substanser som markerar aneurysmtillväxt ledande till ökad risk för bristning, skulle enbart de patienter som löper störst risk kunna erbjudas operation. Forskning pågår för att hitta en medicinsk behandling att erbjuda patienterna för att undvika tillväxt och ruptur.&lt;br/&gt;&lt;br&gt; I denna avhandling studerades hur markörer för inflammation (cytokiner) är relaterade till förekomst och tillväxt av aortaaneurysm. Nivåerna av flera markörer visade sig vara klart förhöjda hos aneurysmpatienter jämfört med hos en kontrollgrupp.&lt;br/&gt;&lt;br&gt; Vi studerade även om blodfettsänkande behandling med så kallade statiner påverkade dessa markörer hos patienter med aortaaneurysm. Statinbehandlade aneurysmpatienter visade sig ha högre nivåer av APC-PCI komplexet och lägre nivåer av homocystein, ämnen av betydelse för blodkoagulation respektive inflammation.&lt;br/&gt;&lt;br&gt; Däremot fanns det ingen relation mellan olika markörer i blodet (MMPs, TIMP-1, serpine-1 t-Pa-serpine-1, APC-PCI komplexet) och aneurysmtillväxt. &lt;br/&gt;&lt;br&gt; Endothelin-1 (ET-1) är en signalsubstans som ger en stark kärlsammandragning. Nivån av cirkulerande endotelin är förhöjd hos patienter med aortaaneurysm. Vi fann dessutom att högre nivåer av ET-1 och större aneurysmdiameter innebär mer uttalad tillväxt av aneurysmet under uppföljning. &lt;br/&gt;&lt;br&gt; Vi studerade även ovanstående markörer och deras förhållande till pulsåderbråckets tillväxt under flera års uppföljning. Inga av ovanstående markörer visade sig erbjuda möjligheten att prediktera tillväxt eller bristning av aneurysmet. Ingen av de markörer vi studerade kan därför ersätta ultraljudsuppföljning av patienter med mindre kroppspulsåderbråck.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis kunde i vår studie inte tillväxt av ett aneurysm predikteras genom analys av någon systemisk markör. Fynden i vår studie kan dock i framtiden bli värdefulla för att följa medikamentell behandling syftande till tillväxtreduktion av aortaaneurysm. Ett flertal olika mekanismer bidrar sannolikt till att aneurysm expanderar storleksmässigt.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/debfad48-d8a0-42fa-934d-cf248bbbd6b7</url> </location> </relatedItem> <originInfo> <publisher>Department of Vascular diseases, Skåne University Hospital Malmö, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>matrix metalloproteinases</topic> <topic>biomarkers</topic> <topic>risk factors</topic> <topic>fibrinolysis</topic> <topic>coagulation</topic> <topic>inflammation</topic> <topic>Abdominal aortic aneurysm</topic> <topic>statin</topic> <topic>interleukin 6.</topic> <topic>APC-PCI complex</topic> <topic>serpine-1</topic> <topic>endothelin-1</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-80-1</identifier> <identifier type="oldLupId">1594472</identifier> <part> <detail type="volume"> <number>2010:64</number> </detail> <extent unit="pages"> <total>82</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-06-04T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>debfad48-d8a0-42fa-934d-cf248bbbd6b7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:50:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-03-17T05:51:47Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:50:58+02:00</recordDateApproved> </recordInfo> </mods>

The main cause of death for women with breast cancer is secondary tumors.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Downregulation of Wnt5a in primary ductal breast cancer has been correlated with poor outcome and higher tumor grade and found to be an independent predictor of recurrence. The ability of Wnt5a to inhibit tumor progression can partly be explained by Wnt5a induced cell-extracellular adhesion that inhibits cell migration. We found that Wnt5a can further inhibit tumor progression by inducing cell-cell adhesion through CK1α-induced Ser-45 phoshporylation of β-catenin promoting β-catenin/E-cadherin complex formation, hence in line with prior data indicating a beneficial effect of Wnt5a in breast cancer. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Macrophages are part of the innate immune system and they can differentiate into tumoricidal pro-inflammatory M1 macrophages or anti-inflammatory M2 macrophages. The anti-inflammatory M2 macrophages will limit pro-inflammatory activity that in abundance would cause additional tissue damage. Tumor associated macrophages (TAMs) have many features in common with M2 macrophages; they are anti-inflammatory and have a weak tumoricidal capacity. We show that Wnt5a induces an anti-inflammatory tolerogenic macrophage phenotype in a pro-inflammatory environment and we could validate our in vitro data by showing the clinical relevance in both breast cancer and sepsis patients.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The CD163 marker has been reported to recognize M2 macrophages, while CD68, on the other hand, is a frequently used pan-macrophage marker that recognizes both pro-inflammatory M1 macrophages and anti-inflammatory M2 macrophages. We evaluated CD163 as a TAM marker in human breast cancer and compared it to CD68. We revealed and could highlight the clinical importance of analyzing the localization of TAMs in human breast cancer. While TAMs in the tumor nest did not have any correlation with clinicopathological feature or patient outcome, we found TAMs in tumor stroma to be highly relevant. CD163+ TAMs in tumor stroma correlated with unbeneficial clinicopathological features, and dense infiltration of CD68+ TAMs in tumor stroma was an independent risk factor for reduced breast cancer specific survival.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d684aa50-0987-4895-9a68-727fb677a619</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Catharina_Medrek_AVHANDLING_kappa.pdf">https://portal.research.lu.se/files/3016188/3049567.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1975067</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Breast cancer</topic> <topic>Wnt5a</topic> <topic>E-cadherin</topic> <topic>B-catenin</topic> <topic>migration</topic> <topic>invasion</topic> <topic>turnor associated macrophages</topic> <topic>CD163</topic> <topic>CD68</topic> <topic>turnor stroma</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-30-2</identifier> <identifier type="oldLupId">3049556</identifier> <part> <detail type="volume"> <number>2012:67</number> </detail> <extent unit="pages"> <total>60</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-09-26T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

It does so by investigating the possible relation between Israeli Muslim women’s choice of religious identification and their individual experiences in everyday life transitions. Many of these women are traveling daily from their hometowns or villages to the major cities in Israel to study or to work. Israeli statistics shows that the socio-economic status of Muslim women in the country have improved over time, and so has the number of Muslim women in Israel that are choosing religion as their dominant identification.The main methodological approach of this disertation is qualitative fieldwork conducted in Israel between 2009 and 2010. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Empirically, this thesis presents a case study founded on interviews with several women. This material is complemented by statistics about Muslim women from various sources. Theoretically, the present thesis is inspired by the ideas of Alain Tourraine on individuals everyday life transitions. At the time of the interviews the women were between 19–26 years old. They all studied at universities in Israel, they all identified themself as religious and were all members of The Islamic Movement in Israel. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the interviews the women express how they understand their choice of religious identification and what religion means to them in everyday life. One chapter is devoted to a historical and statistical overview of Muslims in Israel that ends with specific data about Muslim women in Israel. The interviews are presented in five chapters. The first chapter, “Ummah”, presents how the interviewed women relate to other Muslims in the world. The second chapter discusses the “Prayer”; what prayer means to the women and why they pray. Another chapter examines how they discuss their clothing. A separate chapter is devoted to the women’s attitudes towards modernity. In the fifth chapter the women’s relationship to various interpretations of the Koran is discussed.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In sum, this study of religious Muslim women in Israel advocates that it is significant to focus on everyday life transitions to understand why people chose religion in the construction of personal identities. Consequently, in an increasing global society humans are moving between surroundings that have overlapping, different and some times contradicting expectations on individuals.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hence, this thesis suggests that one way individuals negotiate and facilitate transitions in everyday life is through religious identification.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/845bf07b-8a5f-471c-8f92-2510c80a54c7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Eli_avhandling_2_1_.pdf">https://portal.research.lu.se/files/3017889/2337725.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2220038</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Centrum för teologi och religionsvetenskap, Lunds universitet</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Islam</topic> <topic>Israel</topic> <topic>Muslim Women</topic> <topic>Arabs in Israel</topic> <topic>Palestinians in Israel</topic> <topic>Arab Women in Israel</topic> <topic>religious identity.</topic> </subject> <subject authority="lup"> <topic>Philosophy, Ethics and Religion</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in History of Religions</title> </titleInfo> <identifier type="issn">1103-4882</identifier> <identifier type="isbn">978-91-7473-231-3</identifier> <identifier type="oldLupId">2337673</identifier> <part> <detail type="volume"> <number>30</number> </detail> <extent unit="pages"> <total>199</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-03-28T15:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>845bf07b-8a5f-471c-8f92-2510c80a54c7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:51:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:51:30+02:00</recordDateApproved> </recordInfo> </mods>

Despite standard treatment including surgery, radiotherapy and temozolomide (TMZ)-based chemotherapy, the prognosis for GBM patients is dismal, and there is a need for novel treatments. One possible therapeutic treatment modality presented here is immunotherapy, either alone or combined with intratumoral TMZ. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this doctoral thesis, I report enhanced cure of rats and mice with malignant brain tumors after peripheral immunizations using irradiated whole tumor cells transduced to produce different immunostimulatory cytokines such as interferon-gamma (IFNγ), interleukin-7 (IL-7) and granulocyte macrophage-colony stimulating factor (GM-CSF). In the N32 rat glioma model there is a synergistic therapeutic effect when combining immunization with IFNγ- and- IL7-producing tumor cells and this coincides with enhanced systemic proliferation of CD4+ and CD8+ T cells, and an increase in the plasma levels of IFNγ, thereby strengthening the anti-tumor immune response. In addition the synergistic therapeutic effect of immunization with irradiated GM-CSF-producing tumor cells and recombinant IFNγ in the GL261 mouse glioma model is mediated by both CD4+ and CD8+ T cells, and evokes a long-term memory response that protects against secondary tumors without any further treatment.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Further I report that TMZ and cisplatin, two chemotherapeutic agents, could cure 41-45% of GL261 tumor-bearing mice when delivered intratumorally using micro-osmotic pumps. When immunization with irradiated GM-CSF-producing tumor cells is combined with intratumorally administered TMZ, the survival of tumor-bearing mice is synergistically enhanced, while systemic delivery of TMZ abrogates the effect of the immunotherapy. Cisplatin however, does not boost the effect of the immunotherapy.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, immunotherapy improves survival in experimental glioma models, and the therapeutic effect is enhanced by intratumoral, but not systemic TMZ treatment.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Trots ett sunt leverne med regelbunden motion och nyttig mat kan vi inte alltid förhindra risken att drabbas av vissa typer av cancer som till exempel hjärntumörer. Den vanligaste formen av elakartade hjärntumörer heter glioblastoma multiforme och är också den mest aggressiva. Symptomen varierar beroende på tumörens storlek och var i hjärnan den växer, och patienter kan få problem med andning, huvudvärk, dubbelseende, svindel, krampanfall, personlighetsförändringar samt att göra vardagliga ting som att gå eller äta.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Idag försöker man att behandla majoriteten av alla elakartade hjärntumörer med kirurgi, men tumörens förmåga att infiltrera den omkringliggande normala hjärnvävnaden gör det nästan omöjligt att ta bort hela tumören med kirurgisk hjälp. Operationen kan möjligen minska tumörens storlek och därigenom lindra många symptom. Tyvärr är sannolikheten stor att de tumörceller som finns kvar efter operation återväxer och bildar nya tumörer, vilket gör det mycket svårt att bli av med tumören. Kirurgi kombineras därför med andra behandlingsformer som strålbehandling och cellgifter. Dessa behandlingsformer är dock problematiska eftersom de ofta ger upphov till allvarliga bieffekter. Kroppens egna immunförsvar försvagas till exempel av cellgiftsbehandling vilket kan leda till allvarliga infektioner som kroppen inte kan ta hand om. Dessutom utvecklar tumörer ofta resistens mot dessa behandlingar och därför lever de patienter som drabbats av glioblastoma multiforme endast i ca 15 månader.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Jag har under mitt avhandlingsarbete arbetat med att utveckla ett vaccin mot hjärntumörer. Vi testar vårt vaccin på möss och råttor med hjärntumörer, och vi avser att sedan applicera våra resultat på patienter. Vårt vaccin består av tumörceller som vi manipulerar genetiskt så att de börjar tillverka ämnen som aktiverar immunförsvaret. Innan vi vaccinerar djuren strålar vi tumörcellerna för att förhindra celldelning och bildandet av nya tumörer vid vaccinationsstället. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I mitt första delarbete (Paper I) har jag studerat råttor med hjärntumörer. Jag har visat att om vi kombinerar vårt tumörcellsvaccin med två ämnen som aktiverar immunförsvaret: IFNγ och IL-7, börjar kroppens egna vita blodkroppar att dela sig och blir fler. Dessa vita blodkroppar börjar i sin tur tillverka mer IFNγ. Med hjälp av blodprov från djuren har vi kunnat mäta en höjning av detta ämne i blodet, vilket har gett oss en indikation på att djuren har svarat på behandlingen. De aktiverade vita blodkropparna färdas sedan genom blodet och tar sig in i hjärnan där de känner igen tumörcellerna som främmande/farliga och dödar tumörcellerna. I min första studie blev 75% av de råttor som fick vårt tumörcellsvaccin med IFNγ och IL-7 helt botade från sina hjärntumörer. De råttor som inte fick någon behandling överlevde inte, och av de råttor som bara fick ett av de immunaktiverande ämnena i sitt vaccin, botade vi 19-25%. Detta visade att vaccinering med två immunaktiverande ämnen var mer effektivt än vaccinering med bara ett ämne.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har sett att våra tumörcellsvaccin fungerar i både råttor och i möss men vi vet inte HUR det fungerar. Därför har vi i det andra delarbetet (Paper II, där jag är andra författare) undersökt möss med hjärntumörer för att ta reda på vilka vita blodkroppar som är viktiga för vårt vaccins inverkan på mössens förlängda överlevnad. Ett sätt att ta reda på detta är att ge mössen antikroppar som binder till och tar bort vissa vita blodkroppar och studera hur detta påverkar vaccinets effekt. Om de celler vi tar bort har en viktig roll för effekten av vårt vaccin förväntar vi oss att dessa möss inte överlever lika länge som de som har sina vita blodkroppar kvar. Vi tog bort två typer av vita blodkroppar som heter CD4 T celler och CD8 T celler. Resultatet blev att nästan inga möss klarade av att bekämpa tumören utan CD4 och CD8 T celler, vilket visade att de hade en vital betydelse för effekten av vaccinet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete 3 och 4 (Paper III och IV) har jag förutom att ge mössen vårt tumörcellsvaccin också behandlat dem med två typer av cellgifter: temozolomid och cisplatin. Temozolomid ges som standardbehandling till patienter med hjärntumörer och cisplatin är ett vanligt cellgift som ges till många olika cancerformer. I delarbete 3 jämförde jag att ge mössen en hög dos temozolomid till hela kroppen (ungefär som patienter får läkemedlet idag) med att ge en mycket lägre dos direkt in i tumören. Det visade sig att när cellgiftet gavs direkt in i tumören hade det bättre effekt än när det gavs till hela kroppen (45% jämfört med 8% överlevnad). Genom blodprovstagning av mössen kunde jag också studera effekten av cellgiftet på de vita blodpropparna. De möss som fick höga nivåer av cellgifter i hela kroppen hade färre vita blodkroppar i blodet än de möss som fick lokal cellgiftsbehandling, vilket betyder att det är mindre skadligt för immunförsvaret att ge cellgifterna direkt in i tumören. Därefter testade jag att ge cellgiftet på de två olika sätten tillsammans med tumörcellsvaccinet. Av de möss som bara blev vaccinerade blev 25% botade av tumören. De möss som hade vaccinerats och sedan fick en hög dos av cellgift i hela kroppen lyckades inte överleva, vilket tyder på att cellgifterna dödade de viktiga vita blodkropparna (t.ex. T cellerna) ansvariga för den tumördödande effekten av vaccinet. Däremot överlevde 83% av de möss som fick vaccinet och sedan lokal cellgiftsbehandling, vilket visade att T cellerna inte dog av lokal cellgiftsbehandling utan fanns kvar och kunde tillsammans med cellgiftet bekämpa tumören.&lt;br/&gt;&lt;br&gt; I delarbete 4 visade jag att även lokal behandling av cisplatin också kunde bota 41% av djuren, men att höga doser av cisplatin lokalt i hjärnan även hade allvarliga biverkningar vilket visar vikten av att ge rätt dos av det injicerade cellgiftet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har tidigare testat ett vaccin på patienter som bygger på resultat från våra djurstudier. Patienters tumörceller manipulerades så att de tillverkade IFNγ och sedan injicerades de in i patienterna. Vi såg en förlängd överlevnad hos vaccinerade patienter med 6-7 månader jämfört med patienter som fick standardbehandling. Förbättringarna som nu gjorts av vaccinet kommer nog i framtiden att möjliggöra en förlängning av överlevnaden hos dessa patienter. Om vi dessutom ger vaccinet med lokal cellgiftsbehandling skulle patienternas överlevnad förhoppningsvis kunna förlängas ytterligare.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/dca7a7a2-8dcd-409d-a36e-89a339541414</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis-Sara_Fritzell.pdf">https://portal.research.lu.se/files/3017946/3736426.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">6063275</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine, Neurosurgery</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Cisplatin</topic> <topic>Glioma</topic> <topic>GM-CSF</topic> <topic>IFN-gamma</topic> <topic>IL-7</topic> <topic>Immunotherapy</topic> <topic>Intratumoral chemotherapy</topic> <topic>Temozolomide</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-34-5</identifier> <identifier type="oldLupId">3736408</identifier> <part> <detail type="volume"> <number>2013:64</number> </detail> <extent unit="pages"> <total>89</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-06-01T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>dca7a7a2-8dcd-409d-a36e-89a339541414</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:51:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:51:31+02:00</recordDateApproved> </recordInfo> </mods>

Moderate and severe symptoms of diabetes presentation require infusion therapy and thereby necessitate hospitalisation for the first few days. The initial management is&lt;br/&gt;&lt;br&gt; largely a preparation for family members to help them gain the practical understanding and skills needed for integrating the treatment in everyday life. Some units routinely admit the children to hospital, while others say they can be safely managed at home. There is no high-quality evidence concerning the consequences that the differences in the type of service might have for the child, family or health system. The overall aim of this thesis was to investigate the initial care for children newly diagnosed with type 1 diabetes, receiving conventional hospital-based care and hospital-based home care (HBHC), i.e. specialist care in a home-based setting. A further aim was to identify families where the child runs the risk of decreased metabolic control and to give these families increased support. Two studies have been carried out at Skåne University Hospital Lund in Sweden. The first had a retrospective design with the aim of assessing whether temporal changes in the initial management over a ten year period affected children’s metabolic control two years after diagnosis. The results showed that during the years 1997 up to 2006 all children, except one, were admitted to hospital. The duration of the hospital stay decreased from a mean of three weeks to two weeks. Seventy-five per cent of the children were not acutely ill (defined as pH ≥7.30) at diagnosis and 94% of the children initially received intravenous insulin treatment. Neither the length of the hospital stay nor any differences in insulin treatment were associated with children’s metabolic control over time. The second study had a randomised design with the aim&lt;br/&gt;&lt;br&gt; of comparing two different regimes for children diagnosed with type 1 diabetes: hospital-based care and HBHC. The follow-up of the study was two years. In this thesis, results one and six months from diagnosis are presented. No adverse events or severe acute diabetes complications have occurred during the trial or during the&lt;br/&gt;&lt;br&gt; follow-up. Results one month from diagnosis showed small advantages to HBHC in the children’s metabolic control with regards to plasma glucose values and numbers of episodes of hypoglycaemia. Parents were more satisfied with the service in HBHC, and healthcare costs were 30% lower in HBHC compared to the hospital-based&lt;br/&gt;&lt;br&gt; service. The results six months from diagnosis showed that parents continued to be more satisfied with the service in HBHC. Furthermore, the results showed that there were no differences in the children’s HbA1c, in the arrangement of the parents’ working hours after the child’s diagnosis or in the amount of absence from work&lt;br/&gt;&lt;br&gt; related to the child’s diagnosis. The categorical risk for families’ psychosocial distress, assessed by professionals at the time of diagnosis, was associated with subsequent resource use, although not HbA1c. Families that received HBHC had less use of healthcare resources, compared to families having received hospital-based care. When summarising the first month and the period from 1-6 months, the total healthcare costs were 27% lower in HBHC compared to hospital-based care. In summary, for children diagnosed with type 1 diabetes, the length of the hospital stay has decreased significantly over a ten year period. During this time, children have&lt;br/&gt;&lt;br&gt; usually been routinely admitted to hospital irrespective of their medical condition. The results support the suggestion that an HBHC programme is just as safe for the child as hospital-based care. The results further indicate equivalence in the efficacy of the services. These results, in combination with a high degree of acceptance by those to whom the HBHC service was offered and lower healthcare costs, could suggest that the HBHC service is more effective as compared to the conventional hospitalbased care. As a whole, there are not many well-designed and controlled studies that have compared hospital services with different models of home care. This thesis, although limited in answers by power and knowledge stability, provides empirical support for the safety and effectiveness of healthcare services when a child is diagnosed with type 1 diabetes. The evaluation will continue to assess the consequences, of both HBHC and hospital-based care, for the child, family and health services over time and from different perspectives.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/77a46f13-5d86-4fd1-9b80-4bb9976930d3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Iren_Tiberg.pdf">https://portal.research.lu.se/files/3018229/2621132.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1686738</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine, Department of Health Sciences</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Hemoglobin A1c</topic> <topic>Health Resourses</topic> <topic>Health Care Costs</topic> <topic>Family</topic> <topic>Home Care Resvices</topic> <topic>Disease Management</topic> <topic>Patient Satisfaction</topic> <topic>Randomised Controlled Trial</topic> <topic>Research Design</topic> <topic>Type 1 Diabetes</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-10-4</identifier> <identifier type="oldLupId">2543646</identifier> <part> <detail type="volume"> <number>2012:48</number> </detail> <extent unit="pages"> <total>161</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-06-15T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>77a46f13-5d86-4fd1-9b80-4bb9976930d3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:51:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:51:35+02:00</recordDateApproved> </recordInfo> </mods>

Interventions with Affect School and Script Analysis (ASSA) compared to&lt;br/&gt;&lt;br&gt; Basic Body Awareness Therapy (BBAT) are tried.&lt;br/&gt;&lt;br&gt; In a feasibility and treatment efficacy study we offered ASSA to 59 patients with CBP,&lt;br/&gt;&lt;br&gt; and 54 (92%) completed. Alexithymia prevalence went from 33% to 11% (p = 0.013),&lt;br/&gt;&lt;br&gt; depression from 59% to 48% (p = 0.18), and anxiety from 78% to 50% (p = 0.002) in&lt;br/&gt;&lt;br&gt; 46 respondents, and social relations improved (p &amp;lt;0.001).&lt;br/&gt;&lt;br&gt; We have established a protocol of a treatment efficacy, multicenter, open-labelled,&lt;br/&gt;&lt;br&gt; randomized controlled trial with two intervention arms, ASSA and BBAT. Inclusion&lt;br/&gt;&lt;br&gt; criteria: T1D or T2D; HbA1c ≥62.5 mmol/mol; psychological symptoms; age 18-59&lt;br/&gt;&lt;br&gt; years; diabetes duration ≥1 year. Exclusion criteria: pregnancy; severe somatic or&lt;br/&gt;&lt;br&gt; psychiatric disorder; cognitive deficiency; inadequate knowledge of Swedish. Primary&lt;br/&gt;&lt;br&gt; outcome measure: depression prevalence. Secondary outcome measures: HbA1c,&lt;br/&gt;&lt;br&gt; midnight salivary cortisol (MSC), alexithymia and anxiety prevalence, self-image&lt;br/&gt;&lt;br&gt; measures, diabetes complications and mortality in 6 year follow up.&lt;br/&gt;&lt;br&gt; In a cross sectional study of 292 T1D patients, associations between high HbA1c and&lt;br/&gt;&lt;br&gt; psychological factors, life style factors and obesity were tried. 80 patients (27%) had&lt;br/&gt;&lt;br&gt; HbA1c &amp;gt;70 mmol/mol, which was associated with depression (AOR 4.8), abdominal&lt;br/&gt;&lt;br&gt; obesity (AOR 4.3), and smoking (AOR 3.0). Alexithymia and anxiety were linked with&lt;br/&gt;&lt;br&gt; depression.&lt;br/&gt;&lt;br&gt; In a cross sectional study of 196 T1D patients, associations between high MSC (≥9.3&lt;br/&gt;&lt;br&gt; nmol/L), depression, HbA1c, and intra individual, behavioural and environmental&lt;br/&gt;&lt;br&gt; factors were explored. 34 patients (17%) had MSC ≥9.3 nmol/L, which was associated&lt;br/&gt;&lt;br&gt; with smoking (AOR 5.5), spring season (AOR 4.3), physical inactivity (AOR 3.9),&lt;br/&gt;&lt;br&gt; depression (AOR 3.1), and older age (AOR 1.08; (per year)). HbA1c &amp;gt;70 mmol/mol&lt;br/&gt;&lt;br&gt; (AOR 4.2) and MSC ≥9.3 nmol/L (AOR 4.4) were independently linked with&lt;br/&gt;&lt;br&gt; depression.&lt;br/&gt;&lt;br&gt; Conclusions are that alexithymia was linked with depression, which in sum was&lt;br/&gt;&lt;br&gt; associated with both high HbA1c and high MSC in T1D patients. ASSA showed&lt;br/&gt;&lt;br&gt; reduced alexithymia, anxiety and depression and improved social relations in CBP&lt;br/&gt;&lt;br&gt; patients. ASSA for selected patients with diabetes will be further evaluated in an RCT.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Alexitymi, stress, depression, kortisol och diabetes&lt;br/&gt;&lt;br&gt; Alexitymi är ett relativt nytt begrepp som konstruerades 1973 av en psykoanalytiker vid&lt;br/&gt;&lt;br&gt; namn Sifnoes, och betyder ordagrant ”inga ord för känslor”. Alexitymi innebär&lt;br/&gt;&lt;br&gt; framförallt svårigheter att känna igen och beskriva känslor, och dessutom svårigheter&lt;br/&gt;&lt;br&gt; att skilja kroppsliga uttryck för känslor från sjukdomssymptom. Man har tidigare sett&lt;br/&gt;&lt;br&gt; en ökad förekomst av alexitymi vid depression, ångest, och kronisk smärta.&lt;br/&gt;&lt;br&gt; Vid stress påverkas flera olika delar av hjärnan och flera hormonsystem. Syftet med&lt;br/&gt;&lt;br&gt; dessa förändringar är att underlätta överlevnad i hotfulla situationer. Stresshormoner&lt;br/&gt;&lt;br&gt; frigörs, framförallt kortisol och noradrenalin. Andra hormoner som behövs förr tillväxt&lt;br/&gt;&lt;br&gt; och sexualitet hämmas. Sömnbehov och hunger undertrycks. Oro och rädsla aktiveras.&lt;br/&gt;&lt;br&gt; Depression och den akuta stressreaktionen har flera gemensamma egenskaper. Inte&lt;br/&gt;&lt;br&gt; minst viktigt är en ökad utsöndring av stresshormonet kortisol, som påverkar många&lt;br/&gt;&lt;br&gt; funktioner och organ i kroppen. Ökade mängder av kortisol höjer blodtrycket,&lt;br/&gt;&lt;br&gt; blodfetterna, blodsockret, bidrar till bukfetma, minskar muskelmassan, och ökar risken&lt;br/&gt;&lt;br&gt; för benskörhet.&lt;br/&gt;&lt;br&gt; Man har i tidigare forskning visat att det är dubbelt så vanligt med depression hos&lt;br/&gt;&lt;br&gt; människor med diabetes än hos personer som inte har diabetes. Personer med både&lt;br/&gt;&lt;br&gt; depression och diabetes har en ökad risk för samtliga diabeteskomplikationer och har&lt;br/&gt;&lt;br&gt; en högre dödlighet.&lt;br/&gt;&lt;br&gt; Kronisk smärta&lt;br/&gt;&lt;br&gt; Personer med kronisk smärta har enligt tidigare forskning en ökad förekomst av&lt;br/&gt;&lt;br&gt; alexitymi, depression och ångest.&lt;br/&gt;&lt;br&gt; 10&lt;br/&gt;&lt;br&gt; Affekter, Affektskola och Basal Kroppskännedom&lt;br/&gt;&lt;br&gt; När vi föds finns det inprogrammerat i oss människor en förmåga att känna vissa&lt;br/&gt;&lt;br&gt; grundaffekter. Till dessa räknas glädje, intresse, förvåning, ilska, oro, rädsla, skam, avsky&lt;br/&gt;&lt;br&gt; och smärta. Varje grundaffekt har ett specifikt program som inkluderar&lt;br/&gt;&lt;br&gt; ansiktsmimiken, kroppsspråket, rösten, autonoma nervsystemet och de olika&lt;br/&gt;&lt;br&gt; hormonsystemen. Grundaffekterna är till en början omedvetna, men med barnets&lt;br/&gt;&lt;br&gt; utveckling följer en förmåga att känna igen känslor och sätta ord på dem. Hur vi&lt;br/&gt;&lt;br&gt; hanterar våra känslor är beroende av vår livshistoria. Vår uppfostran och den kultur vi&lt;br/&gt;&lt;br&gt; lever i påverkar vilka mönster vi utvecklar för att hantera känslorna.&lt;br/&gt;&lt;br&gt; I affektskolan, som är en behandling 8 gånger i grupp, går vi systematiskt igenom de&lt;br/&gt;&lt;br&gt; kroppsliga uttrycken för de medfödda affekterna. Patienterna får träna på att identifiera&lt;br/&gt;&lt;br&gt; känslor och att beskriva dem i ord. Patienterna får också träna på att identifiera sina&lt;br/&gt;&lt;br&gt; egna inlärda mönster för hur de hanterar sina känslor. Detta fördjupas under 10&lt;br/&gt;&lt;br&gt; enskilda samtal med en terapeut där patienterna själva väljer en eller två affekter de vill&lt;br/&gt;&lt;br&gt; fördjupa sig i.&lt;br/&gt;&lt;br&gt; Vi har provat Affektskolan för patienter med kronisk smärta och vi såg en minskning&lt;br/&gt;&lt;br&gt; av alexitymi, ångest och depression. Många patienter rapporterade också att deras&lt;br/&gt;&lt;br&gt; sociala relationer förbättrades.&lt;br/&gt;&lt;br&gt; Vi har hos typ 1 diabetiker undersökt sambanden mellan långtidsvärdet för blodsockerkontrollen&lt;br/&gt;&lt;br&gt; (HbA1c) och psykologiska faktorer, livsstilsfaktorer och fetma. Vi&lt;br/&gt;&lt;br&gt; hittade lika starka samband mellan depression och dåligt reglerad diabetes som mellan&lt;br/&gt;&lt;br&gt; rökning, fetma och dåligt reglerad diabetes.&lt;br/&gt;&lt;br&gt; Vi gjorde ytterligare en studie där vi undersökte sambanden mellan hög utsöndring av&lt;br/&gt;&lt;br&gt; kortisol nattetid, och depression, livsstilsfaktorer, och omgivningsfaktorer. Det visade&lt;br/&gt;&lt;br&gt; sig då att högt natt-kortisol var relaterat till depression, rökning och fysisk inaktivitet.&lt;br/&gt;&lt;br&gt; Då depression hos diabetiker innebär en starkt ökad risk för diabeteskomplikationer,&lt;br/&gt;&lt;br&gt; ville vi pröva om Affektskolan skulle kunna bidra till en förbättring av den psykiska&lt;br/&gt;&lt;br&gt; hälsan och en förbättrad blodsockerkontroll. Vi har därför planerat en interventionsstudie&lt;br/&gt;&lt;br&gt; för patienter med diabetes som inte mår bra psykiskt, och som inte ligger bra i&lt;br/&gt;&lt;br&gt; sin sockerkontroll. I denna undersökning planerar vi att lotta patienterna till antingen&lt;br/&gt;&lt;br&gt; Basal Kroppskännedom eller Affektskola. Basal Kroppskännedom är en sjukgymnastisk&lt;br/&gt;&lt;br&gt; metod där man strävar efter en ökad integrering mellan kroppen och det egna ”självet”.&lt;br/&gt;&lt;br&gt; 11&lt;br/&gt;&lt;br&gt; Slutsats&lt;br/&gt;&lt;br&gt; Affektskolan gav en minskning av alexitymi, ångest och depression hos smärtpatienter.&lt;br/&gt;&lt;br&gt; Depression hos diabetespatienterna var starkt relaterat till både dåligt reglerad&lt;br/&gt;&lt;br&gt; blodsockerkontroll och höga nivåer av stresshormonet kortisol nattetid. Båda&lt;br/&gt;&lt;br&gt; faktorerna kan påverka prognosen för personer med diabetes. Vi måste därför finna&lt;br/&gt;&lt;br&gt; metoder för att åtgärda den psykiska ohälsan. Eftersom Affektskolan hade en positiv&lt;br/&gt;&lt;br&gt; inverkan på den psykiska hälsan hos patienter med kronisk smärta, kan den därför vara&lt;br/&gt;&lt;br&gt; värd att prövas även för patienter med diabetes, dåligt reglerad blodsockerkontroll och&lt;br/&gt;&lt;br&gt; psykisk ohälsa.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e115de1c-4aa4-4a2d-a2bf-3a1e961d82b1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Evas_hela_avh_G5.pdf">https://portal.research.lu.se/files/3018978/4814313.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4328120</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Family Medicine, Clinical Sciences, Malmö</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>depression</topic> <topic>Alexithymia</topic> <topic>anxiety</topic> <topic>chronic benign pain</topic> <topic>diabetes mellitus</topic> <topic>midnight salivary cortisol</topic> <topic>HbA1c</topic> <topic>RCT</topic> <topic>Affect School</topic> <topic>Basic Body Awareness</topic> <topic>psychosomatics.</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-077-7</identifier> <identifier type="oldLupId">4814284</identifier> <part> <detail type="volume"> <number>2014:148</number> </detail> <extent unit="pages"> <total>91</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-12-19T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>e115de1c-4aa4-4a2d-a2bf-3a1e961d82b1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:51:46+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:51:46+02:00</recordDateApproved> </recordInfo> </mods>

In this thesis, we identified new mechanisms, whereby HAMLET initiates and executes tumor cell death. HAMLET targets several cellular compartments ranging from the plasma membrane to the nucleus. HAMLET rapidly binds to the plasma membrane of tumor cells and the resulting changes in membrane shape and lipid composition activate ion channels and rapid ion fluxes (paper I). Through macropinocytosis, large amounts of HAMLET enter tumor cells, thus reaching intracellular targets (paper II). By interacting with alpha-actinins, HAMLET facilitates tumor cell detachment and perturbs FAK signaling (paper III). Furthermore, HAMLET interacts with HK1, a member of the glycolytic machinery, and thereby disrupts tumor cell metabolism (paper IV). HAMLET also triggers ER stress (paper I). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This provides a framework for HAMLET’s ability to rapidly kill a wide range of tumor cells and addresses three major HAMLET questions. 1. How are the tumor cells killed? 2. How is HAMLET internalized by tumor cells? 3. Why do normal differentiated cells survive? We show that HAMLET-induced cell death is initiated at the plasma membrane and requires functional ion channels and p38 MAPK signaling. We identify macropinocytosis as a route for HAMLET internalization and distinguish this process from cell death. Finally, we show that the HAMLET sensitivity reflects tumor cell characteristics, such as c-Myc oncogene expression and altered metabolism, as inhibition of glycolysis increased HAMLET sensitivity. Interestingly, HAMLET does not appear to perturb the membranes of normal differentiated cells, further explaining the tumor selectivity.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a632e3a8-6936-4758-a92b-cf9bc55fd123</url> </location> </relatedItem> <originInfo> <publisher>Department of Microbiology, Immunology and Glycobiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>HAMLET</topic> <topic>alpha-lactalbumin</topic> <topic>cancer</topic> <topic>cell death</topic> <topic>ion channels</topic> <topic>p38</topic> <topic>cell detachment</topic> <topic>alpha-actinin</topic> <topic>endocytosis</topic> <topic>macropinocytosis</topic> <topic>c-Myc</topic> <topic>glycolysis</topic> </subject> <subject authority="lup"> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-45-1</identifier> <identifier type="oldLupId">2199760</identifier> <part> <detail type="volume"> <number>2011:96</number> </detail> <extent unit="pages"> <total>198</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-11-18T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>a632e3a8-6936-4758-a92b-cf9bc55fd123</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:51:51+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:51:51+02:00</recordDateApproved> </recordInfo> </mods>

Factors contributing to the induction of NAb may include the strength and duration of antigenic stimulation, the preservation of CD4+ T and B cells, the conformation of the HIV-1 envelope glycoprotein complex (Env), and the evolution of Env during infection. To understand these relationships, the experimental model of pathogenic SIV infection in cynomolgus macaques and comparison of HIV-1 and HIV-2 infections in humans were used in this thesis. &lt;br/&gt;&lt;br&gt; In the macaque model we studied in parallel the appearance of NAb and evolution of Env. For the preservation of SIV-specific cellular immune responses, early anti-retroviral treatment was provided. The main finding from this study was that the macaques that controlled viral load after treatment discontinuation displayed limited virus population genetic diversity and divergence, and had an early broad NAb response. On the other hand, the macaques with no or transient control of viremia showed greater virus diversity and divergence, and potent NAb response during the early period of infection. We propose that the early phase of viral evolution and the antigenic stimulation contributes to the development of NAb and control of viremia. &lt;br/&gt;&lt;br&gt; In humans, HIV-2 is known to be less transmissible and less pathogenic than HIV-1. Therefore, valuable insight can be gained into HIV immunopathogenesis from studies of HIV-2 cohorts with their high proportion of long-term non-progressors. In order to analyze differences in NAb in these infections, we compared, side by side, the breadth and potency of neutralizing activity (NAc) in plasma of HIV-1, HIV-2, and dually HIV-1/2 (HIV-D) infected individuals from Guinea-Bissau against HIV-1 and HIV-2 virus panels. The striking finding was that NAc in HIV-2 plasma against HIV-2 isolates was broader and more potent than NAc in HIV-1 plasma against HIV-1 isolates. Moreover, HIV-D positive individuals had broader and more potent NAc against HIV-2 isolates than HIV-1 isolates, indicating distinct immunogenicity and/or antigenicity of HIV-2 compared to HIV-1. We next analyzed the relative role of IgG and IgA for NAc in HIV-1, HIV-2 and HIV-D plasma. Similarly to the plasma NAc, IgG neutralizing antibodies were found to be more potent in HIV-2 plasma against HIV-2 compared to IgG from HIV-1 plasma against HIV-1. Interestingly, while HIV-2 neutralizing IgA was frequently detected in plasma of HIV-2 infected individuals, HIV-1 neutralizing IgA could rarely be demonstrated in HIV-1 plasma. To study humoral immunity in HIV-1 and HIV-2 infections further, we investigated the role of complement (C’) in antibody-dependent complement-mediated inactivation. Here results showed that the C’ effect on antiviral activity against HIV-2 was more pronounced in HIV-2 plasma than the C’ effect on HIV-1 plasma against HIV-1. Analysis of HIV-D plasma corroborated that the antibody-dependent complement-mediated inactivation was more efficient against HIV-2. This finding suggests that antibody binding to HIV-2 Env facilitates efficient use of C’. In summary, this thesis may provide insights into the nature of broad and potent neutralizing humoral immune responses.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Thirty years after the discovery of HIV, the AIDS epidemic is still with us. While the incidence is declining globally and access to anti-retroviral therapy for low- and middle-income countries is improving, the number of new HIV infections is still high. Despite stubborn efforts to design viral immunogens, an effective formulation for the induction of broad and potent neutralizing antibody response has yet to be found. In this thesis, we tried to elucidate factors contributing to the elucitation of broad and potent virus neutralizing antibodies in an experimental monkey model. Moreover, we aimed to obtain clues to the understanding of the role humoral immunity in the benign course of HIV-2 infection. This achieved by comparing plasma neutralizing antibody responses and the effect of complement on plasma antiviral activity in HIV-1 and HIV-2 infected individuals living in Guinea-Bissau. We hope that our results may provide insights into the nature of broad and potent neutralizing humoral immune responses.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/07008d32-22e6-49ca-bb1c-c3a656f1177b</url> </location> </relatedItem> <originInfo> <publisher>Virology unit, Dept of Laboratory Medicine</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>HIV-1</topic> <topic>HIV-2</topic> <topic>SIV</topic> <topic>envelope</topic> <topic>neutralizing antibody</topic> <topic>breadth</topic> <topic>potency</topic> <topic>IgG</topic> <topic>IgA</topic> <topic>complement</topic> <topic>antibody-dependent complement-mediated inactivation</topic> <topic>virus evolution</topic> <topic>diversity</topic> <topic>divergence</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-49-4</identifier> <identifier type="oldLupId">3123310</identifier> <part> <detail type="volume"> <number>2012:86</number> </detail> <extent unit="pages"> <total>126</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-10-20T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>07008d32-22e6-49ca-bb1c-c3a656f1177b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:51:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:51:53+02:00</recordDateApproved> </recordInfo> </mods>

The interpretation of these histological changes is subjective and suffers from considerable inter-observer variation among pathologists. In study I, we devised and tested two clinically applicable methods for immunohistochemical assessment of p53 and Ki67 as surrogate dysplasia markers. Using these methods, the inter-observer agreement improved substantially from mean k value 0.24 for H&amp;amp;E evaluation to 0.71 and 0.52 for p53 and Ki67 evaluations, respectively. There was a correlation between severity of dysplasia, p53 over-expression and shift of the proliferation zone towards the mucosal surface. We conclude that our methods are reproducible and associated with less inter-observer variation than morphologic dysplasia grading, and that p53 and Ki67 are useful supplementary prognostic markers. The origin of columnar metaplasia in esophagus is debated. The submucosal glands have been proposed as a stem cell source, but studies of the human esophageal glands are rare. In studies II – IV, we conducted comparative and descriptive analyses of the distribution and morphology of the submucosal glands in patients with columnar metaplasia in esophagus. We have shown that there is an accumulation of submucosal glands beneath the transformation-zones between squamous and columnar mucosa, and that the submucosal glands in the columnar lined part of esophagus are hyperplastic. There are overlapping immunophenotypes between the submucosal gland unit, the columnar metaplasia and the transformation-zones for the markers CK17, CK4 and lysozyme. We propose that the submucosal glands are the esophageal counterparts of skin adnexa as a source of re-epithelialization, and conclude that in esophagus both neosquamous islands and columnar metaplasia originate in the submucosal gland unit.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3a559502-eb53-4ea8-97ad-f0e96186a4dc</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Ester_LAPrinc.pdf">https://portal.research.lu.se/files/3020272/5157021.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">24595060</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Columnar lined esophagus</topic> <topic>Barrett´s esophagus</topic> <topic>submucosal gland</topic> <topic>multilayered epithelium</topic> <topic>p53</topic> <topic>Ki67</topic> <topic>CK17</topic> <topic>skin appendage</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-112-5</identifier> <identifier type="oldLupId">5156627</identifier> <part> <detail type="volume"> <number>2015:33</number> </detail> <extent unit="pages"> <total>68</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-04-24T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>3a559502-eb53-4ea8-97ad-f0e96186a4dc</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:51:59+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:51:59+02:00</recordDateApproved> </recordInfo> </mods>

It is proposed that the HSC niche is hypoxic, a milieu within which the HSC is protected from intrinsic and extrinsic stimuli. We have investigated the haematopoietic phenotype of an HSC in a mouse model where hypoxia-regulated Vegfa expression is abrogated. In Vegfaδ/δ mice, the HRE in the Vegfa promoter has been deleted at both alleles, thereby inhibiting HIF-binding and subsequent activation of Vegfa expression following hypoxia. We show that hypoxic regulation of Vegfa expression within the haematopoietic system affects haematopoietic differentiation and numbers of HSCs to a small extent. Interestingly, Vegfa expression was shown to be reduced in highly purified HSCs from bone marrow of Vegfaδ/δ mice but not in mature cells, suggesting that the niche of the HSC is hypoxic.&lt;br/&gt;&lt;br&gt; Acute lymphoblastic leukaemia (ALL) is the most common malignancy among children. Contemporary treatment protocols result in cure rates of 80-85% but 15-20% of children still experience relapse. A group of patients do therefore not benefit from conventional therapy underlining the urgent need to identify additional biomarkers at diagnosis. We have investigated the expression of VEGF-A, its receptors VEGFR-1 and VEGFR-2 as well as PTEN and SHP1 in childhood ALL using immunohistochemistry. We observed that the expression of VEGFR-1, PTEN and SHP1 in mononuclear cells of children with ALL were significantly different to the expression of mononuclear cells in children with no malignant disease. VEGFR-1, PTEN and SHP1 may be potential prognostic factors for childhood ALL.&lt;br/&gt;&lt;br&gt; Chromosomal translocations are reported in approximately 65% of all acute leukaemias. Reports have identified leukaemic translocations in human peripheral blood of healthy individuals supporting the hypothesis that leukaemic transformation is a multistep process. The t(10;11)(p13-14;q14-21) translocation is a reciprocal translocation and forms both an in-frame CALM·AF10 and AF10·CALM fusion. The long latency period prior to the onset of leukaemia in CALM·AF10 mice models suggests that the fusion protein alone does not cause leukaemic development. We hypothesise that AF10·CALM is required for the full leukaemic phenotype. In an in vitro model, we found that t(10;11)(p13-14;q14-21) reciprocal fusions have individual effects on cell biology and, when found in combination, have either a more pronounced or an inhibitory effect on leukaemogenesis. This highlights the importance of examining both fusion proteins in a two transcript reciprocal translocation as they on their own may have individual characteristics.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/81acb1b5-dadf-4f0a-8ce9-735cee81dba7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_Eva_Diffner.pdf">https://portal.research.lu.se/files/3020392/1609694.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4900395</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Center for Molecular Pathology, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-92-4</identifier> <identifier type="oldLupId">1609693</identifier> <part> <detail type="volume"> <number>2010:76</number> </detail> <extent unit="pages"> <total>110</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-06-18T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>81acb1b5-dadf-4f0a-8ce9-735cee81dba7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:02+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:02+02:00</recordDateApproved> </recordInfo> </mods>

Understanding the mechanisms involved in galectin functions will help to find selective and novel strategies for disease treatment and diagnosis. A key to this lies in their carbohydrate binding specificity and the multivalent effects taking place on a cell surface in their presence. The aim of this thesis was to deepen our understanding of galectin recognition and correlate it to biological function.&lt;br/&gt;&lt;br&gt; In paper I we altered the fine specificity of galectin-3 using site directed mutagenesis, and evaluated the effect of this in two biological systems: the ability of extracellular galectin-3 to activate neutrophil leucocytes and intracellular galectin-3 to direct intracellular targeting. A clear correlation was found between fine specificity, as measured with glycan array and fluorescence anisotropy, and biological activity. The most striking effect was the total loss of affinity for the galectin-3 preferred ligand LacNAc when substituting Arg186 to Ser or Ile; these mutants were incompetent in binding and activating neutrophils, and did not enter intracellular vesicles. Galectin-1 does not have the same multifaceted binding specificity as galectin-3. However, its ability to cross-link cell surface receptors has been shown to be of great importance for biological function. In paper II, we therefore analysed the role of galectin-1 dimerisation in high affinity ligand binding using a mutant with strongly reduced ability to form dimers. Surprisingly, high affinity binding of small synthetic divalent ligands as well as multivalent ligands, such as asialofetuin and serum glycoproteins, did not depend much on the dimeric state of galectin-1, but was instead mainly due to added weak interactions within the same carbohydrate recognition domain. In paper III, we studied the modulating effect of the synthetic anti-angiogenic peptide anginex that has been shown to interact with galectin-1, and found that it greatly enhanced the affinity of galectin-1 for various glycoproteins. This raises the question if there is a natural counterpart to anginex in vivo.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Våra celler är täckta av kolhydrater (socker) som är kopplade till proteiner och lipider på cellens yta. Olika celler presenterar olika socker, och en och samma cell kan dessutom ändra sitt sockeruttryck beroende på hur den mår och vad den vill utföra, till exempel dela sig eller dö, en effekt man ofta ser i cancer. På så sätt fungerar sockerstrukturerna som en kod som cellen använder för att kommunicera med sin omgivning. Dessutom använder sig många bakterier och virus, till exempel influensaviruset, av cellytans socker för att ta sig in i celler och orsaka sjukdom.&lt;br/&gt;&lt;br&gt; Hos människan finns flera tusen olika sockerstrukturer, och för att koden som dessa skriver ska resultera i handling, måste den läsas av. Denna uppgift sköts bland annat av sockerbindande proteiner (lektiner), varav galektinerna är en intressant familj. Galektinfamiljen har 15 medlemmar (galektin-1 ¬till -15) som finns mer eller mindre utspridda i kroppen. Genom att läsa den sockerkod som en cell presenterar deltar galektiner i många av cellens grundläggande funktioner så som tillväxt, död och vidhäftning. De kan ha olika funktion i olika celler, och funktionen är ofta helt beroende av vilka socker som cellen presenterar. Galektiner har dessutom visat sig ha en stark koppling till inflammation och cancer, och det finns därför ett väldigt stort intresse för att klarlägga deras struktur och funktion. Denna avhandling fokuserar på just detta, nämligen hur galektiners struktur och sockeravläsande specificitet påverkar deras biologiska funktion.&lt;br/&gt;&lt;br&gt; Galektin-3 är ett av de mest välstuderade galektinerna, och har visat sig binda förvånansvärt många olika sockerstrukturer. Vi ville studera hur denna breda bindningsspecificitet är kopplad till proteinets biologiska funktion (arbete 1). Genom att mutera proteinet (ändra dess struktur) kunde vi göra så att galektin-3 band bättre eller sämre till vissa sockerstrukturer, samtidigt som det behöll bindningen till andra. Vi kunde till och med helt ta bort bindningen till LacNAc, den struktur som galektin-3 binder helst och som är väldigt vanligt förekommande på cellytor. En välstuderad effekt av galektin-3 är dess förmåga att aktivera neutrofiler, vilka fungerar som kroppens försvarsceller vid till exempel en bakterieinfektion. För att undersöka hur den ändrade bindningsspecificiteten hos mutanterna påverkade galektins-3s biologiska funktion använde vi därför förmågan att aktivera neutrofiler som ett modellsystem. Vissa mutanter hade helt tappat denna förmåga, medan andra hade en ökad förmåga att göra samma sak. Med hjälp av mutanterna kunde vi således öka vår förståelse för vilka aspekter av galektin-3s breda bindningspecificitet som var viktiga för denna funktion. Vi jämförde också mutanternas lokalisation i cancerceller, och kunde även här visa att bindningsspecificiteten var viktig.&lt;br/&gt;&lt;br&gt; Galektiner binder många socker med relativt låg bindningsstyrka (affinitet). Naturen har löst detta genom att sätta på flera sockermolekyler på en och samma ligand (bindningspartner), vilket ökar den totala bindningsstyrkan. Detta kräver dock att även det bindande proteinet har mer än en bindningsdomän. Galektin-1 har förmågan att bilda en så kallad dimer, vilket innebär att den sätter ihop två bindningsdomäner och därmed kan binda två ligander samtidigt. Denna egenskap har visat sig viktig för många av dess biologiska funktioner. För att studera detta i detalj använde vi oss av en mutant som inte bildar sådana dimerer och undersökte hur detta påverkade bindningen till olika ligander innehållande flera sockermolekyler som galektinet kan binda, till exempel proteiner som finns i blod (arbete 2). Vi fann att den dimera formen av galektin-1 inte krävdes för att åstadkomma stark bindning. Förmågan att bilda dimerer är troligtvis snarare till för att binda ihop olika ligander på cellytan till nätverk och på så sätt koncentrera specifika ligander i områden som kan fungera som en plattform för att skicka signaler in i cellen.&lt;br/&gt;&lt;br&gt; Tumörceller tillväxer ohämmat och kräver ständig tillgång till näringsämnen. De har därför skaffat sig förmågan att skapa nya blodkärl i sin omgivning. Anginex är en liten peptid som har visat sig hindra denna nybildning av blodkärl genom att samspela med galektin-1. I arbete 3, studerade vi hur detta samspel går till på molekylär nivå. Eftersom galektin-1 ökar blodkärlsbildningen trodde vi att anginex skulle hindra galektin-1s bindning till socker, men till vår stora förvåning visade det sig vara precis tvärtom. Vi fann att tillsammans med anginex band galektin-1 flera tusen gånger bättre till vissa ligander. Så hög bindningsstyrka som vi fann här med anginex, har aldrig tidigare rapporterats för en monovalent interaktion (när en bindningdomän binder en ligand) mellan ett galektin och en ligand. Att en konstgjord peptid kan ha så dramatiska effekter på sockerbindningen väcker frågan om det finns en naturlig motsvarighet.&lt;br/&gt;&lt;br&gt; Galektiner är inblandade i många allvarliga sjukdomstillstånd så som cancer och autoimmuna sjukdomar d.v.s. när immunförsvaret angriper kroppens friska vävnad. Intresset för att förstå hur galektiner fungerar är därför väldigt stort. I denna avhandling presenterar vi data som ökar vår kunskap om hur strukturen hos proteinet är kopplad till dess biologiska funktion, vilket i sin tur ökar vår förståelse för deras roll i cancer och inflammation. Kunskap som denna kan vara avgörande för utvecklingen av nya läkemedel mot dessa sjukdomar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/22bd04e9-9201-4069-96c5-180d9d96f693</url> </location> </relatedItem> <originInfo> <publisher>Emma Salomonsson</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>galectin</topic> <topic>specificity</topic> <topic>affinity</topic> <topic>multivalency</topic> <topic>fluorescence anisotropy</topic> <topic>glycan array</topic> <topic>serum glycoproteins</topic> <topic>anginex</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-78-5</identifier> <identifier type="oldLupId">1857459</identifier> <part> <detail type="volume"> <number>2011:30</number> </detail> <extent unit="pages"> <total>150</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-04-15T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>22bd04e9-9201-4069-96c5-180d9d96f693</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:11+02:00</recordDateApproved> </recordInfo> </mods>

As an example, real-time applications such as computer games have completely different restrictions and demands than offline rendering of feature films. A game has to render quickly using only limited resources, yet present visually adequate images. Film and visual effects rendering may not have strict time requirements but are still required to render efficiently utilizing huge render systems with hundreds or even thousands of CPU cores.&lt;br/&gt;&lt;br&gt; In real-time rendering, with limited time and hardware resources, it is always important to produce as high rendering quality as possible given the constraints available. The first paper in this thesis presents an analytical hardware model together with a feed-back system that guarantees the highest level of image quality subject to a limited time budget.&lt;br/&gt;&lt;br&gt; As graphics processing units grow more powerful, power consumption becomes a critical issue. Smaller handheld devices have only a limited source of energy, their battery, and both small devices and high-end hardware are required to minimize energy consumption not to overheat. The second paper presents experiments and analysis which consider power usage across a range of real-time rendering algorithms and shadow algorithms executed on high-end, integrated and handheld hardware.&lt;br/&gt;&lt;br&gt; Computing accurate reflections and refractions effects has long been considered available only in offline rendering where time isn’t a constraint. The third paper presents a hybrid approach, utilizing the speed of real-time rendering algorithms and hardware with the quality of offline methods to render high quality reflections and refractions in real-time.&lt;br/&gt;&lt;br&gt; The fourth and fifth paper present improvements in construction time and quality of Bounding Volume Hierarchies (BVH). Building BVHs faster reduces rendering time in offline rendering and brings ray tracing a step closer towards a feasible real-time approach.&lt;br/&gt;&lt;br&gt; Bonsai, presented in the fourth paper, constructs BVHs on CPUs faster than contemporary competing algorithms and produces BVHs of a very high quality.&lt;br/&gt;&lt;br&gt; Following Bonsai, the fifth paper presents an algorithm that refines BVH construction by allowing triangles to be split. Although splitting triangles increases construction time, it generally allows for higher quality BVHs. The fifth paper introduces a triangle splitting BVH construction approach that builds BVHs with quality on a par with an earlier high quality splitting algorithm. However, the method presented in paper five is several times faster in construction time.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/26e45244-386c-41e3-95e5-6c76e0fe812f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="phd_final.pdf">https://portal.research.lu.se/files/3021512/8593619.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">60280742</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Computer Sciences</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7623-656-7</identifier> <identifier type="oldLupId">8593599</identifier> <part> <extent unit="pages"> <total>138</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popscienceFaster data structures and graphics hardware techniques for high performance rendering - a popular science summary.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3021510/8599423.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-02-26T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>26e45244-386c-41e3-95e5-6c76e0fe812f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:26+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-12-09T09:29:16Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:26+02:00</recordDateApproved> </recordInfo> </mods>

The area of focus is the competition for professorial chairs in history. The legacy of the discipline viewed history as a holistic concept, binding together most humanistic disciplines. From the perspective of this legacy, the view of empirical specialization was becoming increasingly ambivalent. How can one determine which of two specialist historians is the most qualified one, when they are not specialized in the same field?&lt;br/&gt;&lt;br&gt; The primary sources for this study are academic expert reviews. Throughout the examined period it is a more and more salient feature that expert reviewers end up operating with concepts of personality as a way out of the dilemma described above, the most qualified being the historian with the ideal personality. The charismatic concept of “research personality” was usually contrasted to that of the empirical specialist. Contrary to previous views, the study concludes that the norms of excellence gave a lot more credit to synthesis than has hitherto been believed, albeit as potentiality inherent in the ideal historian’s personality, more than actuality, as in a published work of history. This had a lot to do with an experience of crisis, or lack of institutional purpose for the narrow fields of humanistic inquiry. Hence affirmation of the charismatic research personality served as a kind of regeneration of the humanities in terms of institutional self image.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2324d50f-094e-4365-a20b-eaf6f6e6b250</url> </location> </relatedItem> <originInfo> <publisher>Gidlunds förlag</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>research personality</topic> <topic>expert review</topic> <topic>peer-review</topic> <topic>academic excellence</topic> <topic>conceptual history</topic> <topic>intellectual history</topic> <topic>Nordic historiography</topic> <topic>historiography</topic> <topic>history of historiography</topic> <topic>charismatic personality</topic> <topic>Sweden</topic> </subject> <subject authority="lup"> <topic>History</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Södertörn Doctoral Dissertations</title> </titleInfo> <identifier type="issn">1652-7399</identifier> <identifier type="isbn">978-91-7844-802-9</identifier> <identifier type="oldLupId">1585557</identifier> <part> <detail type="volume"> <number>44</number> </detail> <extent unit="pages"> <total>339</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-07T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>2324d50f-094e-4365-a20b-eaf6f6e6b250</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:34+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:34+02:00</recordDateApproved> </recordInfo> </mods>

Conventional treatment includes surgical revision, continuous irrigation with drainage and wound closure with the use of the greater omentum and muscle flaps.&lt;br/&gt;&lt;br&gt; Widespread adoption of negative pressure wound therapy (NPWT) has been driven through favorable clinical experience and excellent healing effects. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The aims of the research in this thesis were:&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I. To quantify cardiac output and left ventricular chamber volumes after NPWT, using magnetic resonance imaging (MRI).&lt;br/&gt;&lt;br&gt; II. To examine the effects of NPWT on peristernal soft tissue blood flow after internal mammary artery harvesting, using laser Doppler velocimetry.&lt;br/&gt;&lt;br&gt; III. To study the effect of NPWT on blood and fluid content of the sternal wound edge and bone marrow, using MRI (T2-STIR).&lt;br/&gt;&lt;br&gt; IV. To identify the effects of NPWT on the position of the heart in relation to the thoracic wall, using MRI.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; An uninfected porcine sternotomy wound model was used for all studies.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The hemodynamic effects of NPWT in cardiac surgery are debated. MRI measurements show that NPWT results in an immediate decrease in cardiac output, although to a lesser extent than shown in previous studies. MRI is known to be the most accurate method for quantifying cardiac output. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Patients with poor blood perfusion of the sternotomy wound edge tissue have a higher risk of developing post-sternotomy mediastinitis. We show that the peristernal wound edge microvascular blood flow is decreased when the left internal mammary artery is harvested. NPWT therapy stimulates blood flow in the in the wound edge both before and after the mammary artery is removed. Stimulating blood flow to the wound edge in patients with impaired microcirculation may be crucial to ensure healing.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; MRI measurements show that NPWT increases sternotomy wound edge tissue fluid and/or blood content. Presumably, NPWT creates a pressure gradient that draws fluid from the surrounding tissue into the sternal wound edge and into the vacuum source. This “endogenous drainage” may be one possible mechanism by which osteitis is resolved. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Heart rupture is a devastating complication to NPWT of sternotomy wounds. MR imaging shows that NPWT causes the heart to be sucked up towards the thoracic wall and, in some cases, the right ventricular free wall to bulge into the space between the sternal edges and the sharp edges of the sternum to poke into and deform the anterior surface of the heart. These can be effectively hindered by the placement of a rigid barrier over the anterior portion of the heart. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Taken together, the studies of the present thesis demonstrate the effects of NPWT on the thorax and intrathoracic organs. NPWT alters wound edge microvascular blood flow and fluid content and affects heart pumping and heart position in relation to the thoracic wall.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Rainer Petzina, MD&lt;br/&gt;&lt;br&gt; Lund, January 15, 2009</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3e8dc35b-5de8-4f21-862f-fe8089b956ae</url> </location> </relatedItem> <originInfo> <publisher>Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-09-7</identifier> <identifier type="oldLupId">1292157</identifier> <part> <detail type="volume"> <number>2009:22</number> </detail> <extent unit="pages"> <total>67</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-02-27T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>3e8dc35b-5de8-4f21-862f-fe8089b956ae</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:41+02:00</recordDateApproved> </recordInfo> </mods>

Despite improvements in the treatment, a considerable number of patients will relapse and die from their breast cancer. At the same time, a substantial number of patients will be over-treated, as they would have been cured by surgery and radiotherapy alone. In the metastatic setting, only 50% of patients will respond to chemotherapy, but there are no established factors predictive of response to chemotherapy. Therefore there is a need for identification of new prognostic and treatment predictive factors. &lt;br/&gt;&lt;br&gt; In paper I, the chemotherapy predictive value of Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) was assessed in 162 metastatic breast cancer patients. It was found that increasing tumour levels of TIMP-1, reaching borderline significance, were associated with a decreasing probability of response to CMF or anthracycline-containing chemotherapy.&lt;br/&gt;&lt;br&gt; Proliferation, either in the form of single factors or as the main common denominator in different genetic profiles, has been shown to be of independent prognostic value in addition to the already established prognostic factors. In papers II, and IV the proliferation factors Ki67, Mitotic Activity Index (MAI), Phosphohistone H3 (PPH3), cyclin B1, and cyclin A were found to add prognostic value in a retrospective cohort of 237 node-negative premenopausal breast cancer patients, specifically in estrogen receptor (ER) positive patients, and in patients with histological grade 2. Also, in paper IV, when combining two proliferation factors, when either one or two factors were high, the prognostic value was strengthened.&lt;br/&gt;&lt;br&gt; Paper III is a prospective Swedish multicenter validation study assessing the prognostic value of an index composed of the proliferation factor S-phase fraction (SPF), progesterone receptor status (PgR), and tumour size. 576 T1-2N0 breast cancer patients were included. High-risk was defined as ≥2 of the following: 1. tumour size &amp;gt;20mm, 2. PgR-negativity (in the absence of PgR-status, ER-negativity), and 3. high SPF (in the absence of SPF; Bloom-Richardson histological grade 3). High-risk patients had an almost five-fold risk of dying of breast cancer the first 5 years, and an increased risk of breast cancer death even after 15 years. Interestingly, an additional low-risk group was identified, 37% of the patients with no risk factors, who had an excellent 15-year survival rate. The index could therefore be helpful in decisions on risk and choice of adjuvant medical treatment.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Varje år insjuknar mer än 8000 kvinnor i Sverige i bröstcancer, och 5 år efter diagnos är nära 90% fortfarande i livet. Trots att prognosen för majoriteten av patienterna är god, dör 1400 kvinnor årligen av bröstcancer. Till följd av detta pågår mycket forskningsarbete för att finna faktorer som bättre kan förutsäga prognos, prognostiska studier, men även för att finna faktorer som bättre förutsäger svar på specifika behandlingar för att rätt patient skall få rätt behandling, behandlingsprediktiva studier. Därutöver pågår många studier för att finna nya läkemedel och kombinationer av läkemedel.&lt;br/&gt;&lt;br&gt; Idag rekommenderas användande av ett antal patient- och tumörberoende prognostiska faktorer i klinisk rutin. Dessa är ålder, tumörstorlek, förekomst av körtel- eller fjärrmetastaser (TNM-stadium), östrogen- och progesteronreceptorstatus (ER och PgR), histologisk grad, samt förekomst av tillväxtfaktorreceptorn human epidermal growth factor receptor 2 (HER2). Utifrån dessa variabler bestäms vilken behandling som skall ges i tillägg till kirurgi, som är den huvudsakliga botande behandlingen för bröstcancer. Kirurgin består antingen av mastektomi, dvs borttagande av hela bröstet och lymfkörtlar i armhålan, eller sektorresektion där man enbart tar bort en del av bröstet. Samtidigt med en sektorresektion tar man antingen bort alla lymfkörtlar i armhålan, eller så görs en undersökning av vaktpostkörteln, sentinel nodebiopsi, där enbart en eller några körtlar opereras bort. Lymfa från bröstet dräneras via en eller några få vaktpostkörtlar, och endast om man vid operationen finner att dessa vaktpostkörtlar innehåller metastaser, behöver man fortsätta och göra en utrymning av ett större antal körtlar i armhålan. &lt;br/&gt;&lt;br&gt; I stort sätt alla patienter som genomgått en sektorresektion erbjuds tilläggsbehandling i form av strålbehandling mot kvarvarande bröst och eventuellt lymfkörtlar i armhålan, eftersom detta visat sig minska risken får återfall i bröstet och armhålan. Har man genomgått modifierad radikal mastektomi rekommenderas strålbehandling mot bröstkorgsväggen och/eller lymfkörtelstationer särskilt vid stora tumörer, eller vid spridning till körtlar i armhålan. Utöver strålbehandling erbjuds medicinsk tilläggsbehandling till majoriteten av patienterna beroende på patientens och tumörens riskfaktorer i övrigt, för att minska risken för återfall. Om tumören har ett uttryck av östrogen- och progesteronreceptorer erbjuds patienten 5 års endokrin behandling som avser att antingen minska nivåerna av östrogen i kroppen, eller binda in till östrogenreceptorerna, vilket i sin tur förhindrar östrogen att binda in till östrogenreceptorerna. Om risken för återfall bedöms som hög, t.ex. vid låg ålder, stor tumör, avsaknad av uttryck av östrogen- eller progesteronreceptorer, hög histologisk grad (vilket är ett tecken på snabbt växande tumör), spridning till många lymfkörtlar, eller överuttryck av tillväxtfaktorreceptorn HER2, kan patienten erbjudas ytterligare mer intensiv tilläggsbehandling i form av cytostatika och/eller målriktad behandling mot tillväxtfaktorn HER2. Dessa behandlingar har visat sig ytterligare minska risken för återfall i bröstcancer, men cytostatikabehandlingar ger betydligt mer biverkningar än enbart endokrin behandling. Cytostatika ges som regel 6 gånger var tredje vecka, och målriktad behandling mot HER2 var tredje vecka under totalt 1 års tid. &lt;br/&gt;&lt;br&gt; Man räknar med att majoriteten av patienterna i dagsläget skulle botas enbart av kirurgi och strålbehandling, men för att minska återfallen ges till majoriteten av patienterna också medicinsk tilläggsbehandling. Trots att så många patienter får tilläggsbehandling, dör 1400 patienter varje år av bröstcancer i Sverige, och mycket forskning ägnas därför åt att förbättra diagnostiken för att bättre kunna skräddarsy behandlingar till patienter. Det finns ett behov att hitta ytterligare faktorer som kan bättre identifiera vilka patienter som har hög risk för återfall, och som är i störst behov av mer extensiv tilläggsbehandling, s.k. prognostiska faktorer. Utöver detta behövs ytterligare faktorer för att identifiera vilka patienter som kommer att svara på vilken behandling, s.k. behandlingsprediktiva faktorer, för att inte ge behandlingar som inte är effektiva och dessutom för att undvika mycket biverkningar. Studier har visat att bara 50% av patienterna med spridd bröstcancer svarar på cytostatikabehandling, och ungefär lika många svarar på endokrin behandling. Idag har man tillgång till två etablerade behandlingsprediktiva faktorer. Förekomst av östrogenreceptorer i tumören förutsäger om patienten kommer att svara på endokrin behandling, och överuttryck av tillväxtfaktorreceptorn HER2 förutsäger svar på målriktad behandling med trastuzumab, pertuzumab, eller lapatinib som alla riktar sig mot HER2. Det finns idag ingen faktor som används i klinisk rutin som förutsäger eller predikterar för svar på cytostatikabehandlingar. &lt;br/&gt;&lt;br&gt; I det första delarbetet, studerade vi en faktor, TIMP-1 (tissue inhibitor of metalloproteases 1) som uttrycks både av tumörceller och omgivande bindvävsceller. Denna faktor förhindrar framförallt nedbrytning av den normala bindväven som omger tumören, och det är en förutsättning för att förhindra att celler ska kunna sprida sig vidare in i omgivande vävnad. Men man har sett att den paradoxalt nog också har tumörstimulerande effekter, bl.a. har den visats skydda mot den programmerade celldöd, apoptos, som cytostatikabehandling orsakar, samt öka kärlnybildningen, vilket behövs när en tumör tillväxer. Tidigare studier har kunnat visa att patienter med tumörer som har ett högt uttryck av TIMP-1 har sämre prognos än de med lågt uttryck. Vidare har man i en dansk studie kunnat visa att patienter med spridd bröstcancer och tumörer med högt uttryck av TIMP-1 inte alls svarar på den vanligaste sortens kemoterapi. Vi gjorde därför en studie för att bekräfta dessa fynd i en ny patientserie, och kunde finna att det fanns ett liknande samband med högt uttryck av TIMP-1 och sämre svar på cytostatikabehandlingar. Detta talar för att TIMP-1 skulle kunna användas för att finna patienter som inte svarar på den vanligaste sortens behandlingar, och för dessa patienter istället erbjuda annan behandling som skulle kunna vara mer verksam.&lt;br/&gt;&lt;br&gt; I de andra tre arbetena som ingår i avhandlingen studerades prognostiska markörer som anger hur snabbt tumören delar sig och tillväxer, s.k. proliferationsmarkörer, hos patienter som vid operationen hade bröstcancer utan spridning till lymfkörtlarna. I delarbete två har vi fokuserat på en proliferationsfaktor, Ki67, och funnit att högt uttryck av Ki67 är en markör för återfall och död i bröstcancer, även när man tar hänsyn till andra redan kända prognostiska faktorer. Detta gäller fram för allt för patienter som också uttrycker östrogen- och progesteronreceptorer. Det kan tala för att just patienterna med östrogenreceptorpositiva tumörer och högt Ki6 och högre risk för återfall skulle vara betjänta av att man utöver endokrin behandling även ger tilläggsbehandling med cytostatika. I delarbete tre har vi redovisat resultat från en svensk studie som initierades av Svenska Bröstcancergruppen på nittiotalets början och inkluderade patienter från Uppsala-Örebro samt de Södra och Norra Sjukvårdsregionerna. Studien lades upp för att bekräfta data från en tidigare studie där man genom att se tillbaka på tidigare opererade bröstcancerpatienter funnit att ett prognostiskt index, som bestod av de tre faktorerna tumörstorlek, progesteronreceptorstatus och proliferationsfaktorn S-fas, kunde förutsäga återfall och död i bröstcancer 4 år efter operation. I den grupp som bedömdes som högrisk var dödligheten i bröstcancer 5 gånger högre 5 år efter operation än för lågriskgruppen. Studien som ingår i mitt avhandlingsarbete är en prospektiv, framåtsyftande studie, och data från denna studie har kunnat bekräfta och stärka resultaten från den föregående studien. Patienterna med hög risk för återfall har nästan fem gånger ökad dödlighet i bröstcancer efter 5 år, och även efter 15 år är fortfarande dödligheten i bröstcancer nästan dubbelt så hög i högriskgruppen jämfört med lågriskgruppen. Dessa högriskpatienter bör också erbjudas mer extensiv tilläggsbehandling utöver endokrin behandling efter operation. Vi fann också att de patienter som inte har någon av de tre riskfaktorerna hade en mycket bra prognos, då enbart 11 % dött i bröstcancer efter 15 år, trots att majoriteten av dem inte fått någon medicinsk behandling, inte ens endokrin behandling. Denna grupp bör kunna besparas tyngre tilläggsbehandling.&lt;br/&gt;&lt;br&gt; I det sista delarbetet studerades det prognostiska värdet av fem proliferationsfaktorer, mitotic activity index (MAI), phosphohistone H3 (PPH3), cyklin B1, cyklin A och Ki67 en och en samt i olika kombinationer. Både PPH3 och MAI är mått inte bara på om tumörcellerna delar sig fort och tillväxer, utan framför allt på slutresultatet av tillväxt, celldelning (mitos), dvs. hur många celler som faktiskt slutligen delar sig och bildar nya dotterceller. Tidigare studier har visat att alla dessa faktorer är starka prognostiska faktorer för bröstcancer. Alla faktorer har när de skall bedömas sina för- och nackdelar. PPH3 har fördelen att infärgningen i tumörvävnad är mycket tydlig och kontrastrik till skillnad från exempelvis Ki67, vilket gör den lätt att bedöma och dessutom ger god samstämmighet mellan olika bedömare. MAI har fördelen att den redan används i modifierad form i klinisk rutin som en del av histologisk gradering. I denna studie fann vi att högt uttryck av samtliga proliferationsfaktorer kunde förutse återfall och död i bröstcancer inom 10 år. Starkast prognostiskt värde hade MAI, PPH3 och cyklin A, framförallt i de östrogenpositiva patienterna. MAI kunde bäst förutsäga risken för återfall, och när vi kombinerade MAI med en av de andra faktorerna, och minst en av dem var positiv, fann vi att kombinationen gav ännu bättre förutsägelse av risk för återfall. &lt;br/&gt;&lt;br&gt; Målet med mina studier har varit att vara en del i det stora arbetet som pågår för att i framtiden bättre kunna skräddarsy behandlingar till alla bröstcancerpatienter. Sammantaget visar resultaten från dessa studier att TIMP-1 kan användas för att förutse vilka patienter som svarar på cytostatikabehandling, men att större studier behövs för att ytterligare bekräfta dessa data. Dessutom visar studierna att flera olika proliferationsfaktorer kan användas för att identifiera patienter med hög risk för återfall, som bör erbjudas mer extensiv adjuvant behandling, men även patienter med så låg risk för återfall att de bör kunna undvika tyngre behandling med mycket biverkningar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/74fae517-6b5e-412b-9dd0-174d1c96e6e2</url> </location> </relatedItem> <originInfo> <publisher>Oncology, Lund</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Breast cancer</topic> <topic>predictive marker</topic> <topic>resistance</topic> <topic>prognostic factor</topic> <topic>proliferation</topic> <topic>prospective</topic> <topic>TIMP-1</topic> <topic>Ki67</topic> <topic>S-phase</topic> <topic>MAI</topic> <topic>PPH3</topic> <topic>cyclin B1</topic> <topic>cyclin A</topic> <topic>node-negative</topic> <topic>validation</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-23-9</identifier> <identifier type="oldLupId">3734673</identifier> <part> <detail type="volume"> <number>2013;53</number> </detail> <extent unit="pages"> <total>124</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-05-24T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>74fae517-6b5e-412b-9dd0-174d1c96e6e2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:46+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:46+02:00</recordDateApproved> </recordInfo> </mods>

Such information can also have a value to understand the etiology of hematological cancers, since clinical heterogeneity and prognostic therapeutic outcomes have been proposed to associate with the specific developmental stage from which the transformed cells originate. Chromosomal rearrangements involving the mixed lineage leukemia-1 (MLL1) gene result in chimeric fusion proteins that can act as transcriptional regulators, and represents a family of recurrent initiating events in human leukemia. MLL1 translocations can result in diseases with different phenotypic representation, but the underlying reason for why seemingly similar translocation products can cause myeloid, lymphoid or mixed leukemia remain unknown. &lt;br/&gt;&lt;br&gt; Various hematopoietic progenitor cells can serve as a candidate cells for transformation and we addressed this issue of “leukemia initiating competence” in article I, where we developed a conditional (doxycycline inducible) transgenic mouse model of the human chimeric transcription factor Mixed Lineage Leukemia-Eleven Nineteen Leukemia (MLL-ENL). Prospective isolations of hematopoietic progenitor cells at distinct stages of differentiation, followed by their adoptive transfer under continuous fusion gene expression permitted us to monitor their leukemia-initiation and competence. In our work, acute myeloid leukemia (AML) could initiate from several different progenitor subsets. Our study highlighted the importance of using highly defined cell types, as developmentally close myeloid progenitor subpopulations showed dramatically different leukemic competence. HSCs however, were resistant to leukemic transformation and displayed reduced proliferative and repopulating capabilities. In addition, we failed to observe lymphoid leukemia development, which is consistent with most experimental mouse models trying to assess MLL-fusion mediated transformation. This seemingly discrepant finding when compared to human leukemias might be the result of underlying factors such as the instructive/permissive nature of MLL-fusions and/or the normal differentiation potential of the target cell. To this end, we in article II demonstrated that leukemia competence in the mouse was lost upon definitive lymphoid commitment, as only very early lymphoid progenitors (DN1 T cells and BLPs) could develop leukemia; in those cases by evoking a latent myeloid potential of the target cells which ultimately resulted in AML. We further demonstrated that not only could co-occurring mutations impact on the latency of leukemia development, but also that the sequence by which the mutations are acquired can have significant influence on the lineage representation of the developing leukemia. As a final part of this work, we assessed the impact of transdifferentiation on leukemia initiation and found that C/EBPB-mediated transdifferentiation could result in acquisition of leukemia competence in otherwise leukemia incompetent lymphoid committed cells. As transdifferentiation recently has been proposed for therapeutic approaches, these results raise concerns regarding their general feasibility. &lt;br/&gt;&lt;br&gt; Finally, in article III, we evaluated the impact of the ribosomal stress pathway on leukemia initiation, a mechanism that potentially could represent a general approach to target oncogenic cells. We demonstrated that genetic targeting of the 5S RNP-MDM2-TRP53 ribosomal stress pathway delays leukemia initiation significantly, but did not provide significant survival advantages in already established leukemia. Therefore, the ribosomal stress pathway holds limited therapeutic value for AML treatment.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Varje dag producerar vår kropp många miljarder nya blodceller. Dessa celler är livsnödvändiga för att många funktioner i kropp ska fungera. Exempelvis hjälper de till med att skydda oss från sjukdomar, läka skador, och med att transportera syre och avfallsämnen. Blodsystemet (det hematopoetiska systemet) är uppbyggt som en hierarki där hematopoetiska stamceller finns på toppen och stegvis ger upphov till s.k. progenitorer, som är mer och mer begränsade i sin förmåga att producera olika typer av blodceller, och som tillslut differentierar ut och blir mogna blodceller. De flesta av de mogna blodcellerna är kortlivade och behöver därför bytas ut regelbundet och ersättas med nya. Nya blodceller produceras under hela livet från stamcellerna där det är just deras två ”stamcellsförmågor” som gör att de kan upprätthålla denna produktion genom livet; 1) De kan ”självförnya” så att de producerar nya stamceller, och 2) De kan differentiera till mer specialiserade celler. &lt;br/&gt;&lt;br&gt; Genom åren har det gjorts många studier för att förstå utvecklingen av hematopoetiska stam- och progenitorsceller, samt deras differentiering till mogna blodceller. Dessa studier har försett oss med viktig information om hur detta regleras, men också om vad som händer när något går fel. En av de blodsjukdomar som kan uppstå när något går fel är leukemi. Leukemier karakteriseras av att blodceller förändrats och förökar sig okontrollerbart. Man kan tänka sig att förändringen som leder till leukemi skulle kunna ske i ett antal olika celler på olika steg i utvecklingshierarkin – både i stamceller och i progenitorsceller. Den cell som detta sker i och som initierar leukemin kallas för en ”leukemia initiating cell” (leukemiinitierande cell). Beroende på vad detta är för cell kan det leda till olika egenskaper för leukemicellerna. Kunskap om sådana skillnader och vilka celler som har förmågan att initiera leukemier skulle kunna leda till utveckling av bättre behandlingsmetoder mot leukemier, och är därför ett viktigt forskningsområde. &lt;br/&gt;&lt;br&gt; Leukemier som uppstår hos människor har ofta rearrangemang av ”mixed-lineage leukemia” (MLL), vilket innebär att en bit av kromosom 11 har brutits bort och satts ihop med en annan kromosom. Detta är en mutation som kallas för translokation, och som kan leda till att två gener fuserar – ett event som i sin tur kan driva på utvecklingen av en leukemi. I artikel I har vi studerat frågan om vilka celltyper som kan initiera en leukemi genom att skapa en musmodell som uttrycker en sådan fusionsgen som nämns ovan. I denna musmodell med s.k. Mixed Lineage Leukemia-Eleven Nineteen Leukemia (MLL-ENL) kan vi sätta på uttrycket av denna specifika fusionsgen i vilken celltyp vi vill. Vi undersökte vilka olika blodceller som gav upphov till leukemi genom att sätta på uttrycket av MLL-ENL i en rad olika blodcellstyper. Vi såg att leukemin kunde uppstå från flera olika progenitorsceller, men att den även kunde skilja sig åt mellan celltyper som utvecklingsmässigt låg väldigt nära varandra. Oavsett vilken cell som gav upphov till leukemin var det emellertid alltid en leukemi som påverkade en viss grupp av blodceller (de i den myeloida linjen) som uppstod. Överraskande nog upptäckte vi även att leukemin inte kunde uppstå från stamcellerna. &lt;br/&gt;&lt;br&gt; Hos människor ger mutationen vi använde i vår musmodell upphov till leukemier som påverkar flera olika typer av blodcellslinjer (myeloida, lymfoida, eller båda), men i vår modell kunde vi som nämnt bara se myeloida leukemier. Skillnaden mellan observationerna i mus och människa här skulle kunna bero på en rad olika faktorer, t.ex. skillnader i mutationens förmåga att bestämma vilken linje som bildas, men den skulle även kunna bero på vilken linjeförmåga de leukemiinitierande cellerna har från början. För att studera detta utförde vi ytterligare undersökningar på fler celltyper i vår MLL-EML-musmodell (artikel II) och såg att progenitorsceller som var begränsade till att bara kunna ge lymfoida celler inte kunde initiera leukemin. Förutom detta såg vi också att närvaro/kombination av andra specifika mutationer kunde påverka hur snabbt leukemin uppstod, och att ordningen av de olika mutationerna kunde påverka linjetilldelningen. Nya rön har föreslagit att man skulle kunna behandla leukemier genom att omvandla en celltyp till en annan och därigenom differentiera ut och få bort leukemicellerna, men våra resultat här visar att en sådan metod även skulle kunna medföra en risk att man omvandlar celler som normalt inte kan ge upphov till leukemier till sådana som kan det, och att man därför bör vara väldigt aktsam vid användandet av sådana strategier. &lt;br/&gt;&lt;br&gt; Slutligen studerade vi även ribosombiogenesens roll i bildandet av leukemi. Ribosombiogenes, som är processen där ribosomer bildas, är mycket konserverad mellan olika arter och nödvändig för celltillväxt och proliferation (celldelning). Tidigare studier har visat att störningar i denna process leder till en mängd ribosomstressresponser som i sin tur föreslagits kunna utnyttjas vid behandling av leukemi. I vår studie såg vi att ribosomala stressresponser visserligen kunde fördröja initieringen av leukemi, men att de inte hade några starka effekter på leukemier som redan utvecklats, och därmed borde ha en väldigt begränsad potential som behandlingsalternativ.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis belyser vårt arbete viktiga delar av både utveckling och behandlingsmöjligheter för leukemi. Vi har bl.a. visat att leukemiinitiering är begränsad till ett smalt differentieringsfönster inom den tidiga blodcellsutvecklingen, att MLL-ENL-medierad leukemiuppkomst inte kan initieras från de hematopoetiska stamcellerna, och att ribosomala stressresponser inte påverkar redan utvecklad leukemi. Dessa upptäckter ger viktig information om såväl potentiella mål, risker, som möjligheter kopplade till utvecklande och användbarhet av olika leukemibehandlingsalternativ.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d563868c-e3f2-444f-b2de-00b967439351</url> </location> </relatedItem> <originInfo> <publisher>Division of Molecular Hematology (DMH)</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Hematopoiesis</topic> <topic>Luekemia</topic> <topic>Cell of origin</topic> <topic>Leukemia Initiation</topic> </subject> <subject authority="lup"> <topic>Hematology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-245-0</identifier> <identifier type="oldLupId">8812371</identifier> <part> <detail type="volume"> <number>2016:19</number> </detail> <extent unit="pages"> <total>84</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-02-24T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>d563868c-e3f2-444f-b2de-00b967439351</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:49+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:49+02:00</recordDateApproved> </recordInfo> </mods>

Most current pharmacological therapies have severe side effects and are seldom curative. Macromolecular drugs, and in particular nucleic acid based drugs, offer a potential remedy for this situation. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Currently, the absence of efficacious and safe methods to deliver nucleic acids to intracellular sites of action is the main impediment to the introduction of nucleic acid based therapies in the clinic. Viral delivery methods have been demonstrated to efficiently deliver nucleic acids, but also to be associated with severe, occasionally life threatening, immune reactions. Non-viral delivery methods are, so far, not sufficiently efficient for use in the clinic. Many viral and virtually all non-viral macromolecular delivery methods depend on cell surface heparan sulfate proteoglycans (HS PGs) for efficient uptake, however the details of this mechanism and the exact role of the PG has been unclear. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The aim of this thesis was to clarify the role of the cell surface PG in macromolecular uptake processes. It is demonstrated that mammalian cells can internalize extracellular DNA by a pathway strictly dependent on cell surface PGs and this pathway is characterized. Secreted, positively charged, proteins and peptides including the antimicrobial peptide LL-37, are shown to facilitate the uptake process. It is also demonstrated that specific HS epitopes, present on cell surface HS PGs, are pivotal for the uptake of diverse HS binding ligands including polyamines and macromolecular antibody complexes. Finally, using a newly developed method for the isolation of endocytic vesicles, it is demonstrated that both classes of cell surface HS PGs, syndecans and glypicans, are true internalizing receptors capable of intracellular macromolecular delivery.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis advances our understanding of PGs as potential targets for macromolecular delivery vehicles. This understanding will be of aid for the development of future macromolecular drugs to the benefit of the patient.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9642b90b-9c71-402a-bb14-ef9435e82c09</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="awittrup.pdf">https://portal.research.lu.se/files/3026436/1488281.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">667960</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Section of Oncology, Dept of Clinical Sciences.</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>LL-37</topic> <topic>heparan sulfate</topic> <topic>glypican</topic> <topic>endocytosis</topic> <topic>drug delivery</topic> <topic>DNA uptake</topic> <topic>Cancer</topic> <topic>cell penetrating peptides</topic> <topic>non-viral gene delivery</topic> <topic>organelle purification</topic> <topic>proteoglycan</topic> <topic>syndecan.</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-92-9</identifier> <identifier type="oldLupId">1488277</identifier> <part> <detail type="volume"> <number>2009:104</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.jbc.org/content/early/2009/09/25/jbc.M109.036129.long</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-11-06T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>9642b90b-9c71-402a-bb14-ef9435e82c09</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:53+02:00</recordDateApproved> </recordInfo> </mods>

Using individual-level data from Southern Sweden for 1813 to 1968, this work measures the impacts of grain prices during the foetal stage and infant mortality rates during the year of birth on mortality over the full life course, as well as on female socioeconomic status attainment and reproductive health. Specific exposure to measles, scarlet fever and whooping cough are also considered. &lt;br/&gt;&lt;br&gt; Regarding the impact of prices, higher mortality is observed among exposed landless males in old age, while exposed landless females exhibit lower probabilities of dying in adulthood and old age and experience no significant effects on their socioeconomic status attainment and reproductive health. Regarding the impact of disease, sex-specific effects on mortality are observed in adult ages for those born in years with measles and scarlet fever. However, the effect of exposure to whooping cough on mortality is strong and uniform across individuals of different sexes and socioeconomic status. Females exposed to this disease are also less able to attain high socioeconomic status in adulthood and experience worse reproductive health, providing evidence of transfers across generations. This thesis finds that disease has a more important role than diet in determining the length and quality of life.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/26071b90-1bbf-4bf9-90df-777f248788ae</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Quaranta_thesis.pdf">https://portal.research.lu.se/files/3026458/3737380.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2933947</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Early life</topic> <topic>selection and scarring</topic> <topic>diet and disease</topic> <topic>life course</topic> <topic>historical demography</topic> <topic>southern Sweden</topic> <topic>19th and 20th century</topic> </subject> <subject authority="lup"> <topic>Economic History</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in Economic History</title> </titleInfo> <identifier type="issn">1400-4860</identifier> <identifier type="oldLupId">3737363</identifier> <part> <detail type="volume"> <number>59</number> </detail> <extent unit="pages"> <total>242</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-06-05T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>26071b90-1bbf-4bf9-90df-777f248788ae</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:53+02:00</recordDateApproved> </recordInfo> </mods>

To characterize and predict these degradation phenomena, a comprehensive high-resolution data base on erosive rainfall, together with siltation records for 28 small reservoirs were analyzed. The studied small reservoir network displays a general life-span of about 14 years. The average soil loss is 14.5 tonnes/ha/year. The complex relationship between the erosive rainfall events and the annual soil loss rates can be explained by two important factors. The first factor is related to the soil “degradation cycle”. It determines the soil particle delivery potential of the catchment. The second factor corresponds to the “degradation front”. The latter presents a north-western/south-eastern direction. To investigate rainfall disaggregation possibilities, a regionalization of fine time-scale and daily rainfall was undertaken. The results showed that the spatial properties are typically non-isotropic. Clustering showed that two&lt;br/&gt;&lt;br&gt; different homogeneous rainfall subgroups are closely related to the predominant convective and frontal rainfall types.&lt;br/&gt;&lt;br&gt; The comparison illustrated important similarities between the maximum 15-min and the daily rainfall data.&lt;br/&gt;&lt;br&gt; The above findings were an incentive to explore the multiplicative properties of a 4-year rainfall time series. The time series showed scaling behavior for time scales up to 100 min that coincides with the most active erosion process time scale. Moreover, the temporal structure of rainfall was reproduced using a disaggregation model (Olsson, 1998). The observed and generated rainfall time series displayed several similar characteristics. This allowed the reproduction of erosivity for erosive rainfall events longer than 45 minutes. The erosion modeling was performed using the USLE/GIS approach. Maps of observed and generated spatial erosion distribution were combined with the Masson’s and Wischmeier-Smith’s erosion limit intervals. According to the above, the potential of rainfall scaling-based approaches to predict water erosion levels in semiarid areas seems promising. Using this approach may help soil and water authorities in semiarid areas to better manage soil erosion problems.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/744b8ed6-c874-4e94-b8a5-aa592d622883</url> </location> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>reservoir siltation</topic> <topic>regionalization</topic> <topic>fractal analysis</topic> <topic>Atlasic mountain range</topic> <topic>erosive events</topic> <topic>semiarid area</topic> <topic>soil loss</topic> <topic>Tunisia.</topic> </subject> <subject authority="lup"> <topic>Water Engineering</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">1939730</identifier> <part> <extent unit="pages"> <total>135</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-06-12T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>744b8ed6-c874-4e94-b8a5-aa592d622883</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:54+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-30T12:42:03Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:54+02:00</recordDateApproved> </recordInfo> </mods>

This leads to discomfort for the occupants. In Maputo City, the capital of Mozambique, electrical devices such as fans and air conditioners are used to obtain a comfortable indoor climate. The cost of electricity is a problem for consumers who have low incomes. Therefore, many cannot afford to pay their electricity bills, leading to conflict with supply company.&lt;br/&gt;&lt;br&gt; In the developing countries, the main use of energy is for lighting, cooling, heating and appliances used in buildings. Approximately 50% of the electricity used in Mozambican buildings is used to produce an artificial indoor climate, by heating, cooling, ventilation and lighting. If building designs were improved taking into account the local climatic and environmental conditions, as well as material specifications, significant gains would be achieved in terms of energy efficiency. This would reduce the need for retrofitting to achieve a comfortable indoor climate. The use of passive strategies to reduce the use of electricity to achieve thermal comfort does not significantly increase the final cost of ordinary buildings, and these strategies require little or no maintenance. The research described in this thesis deals with strategies for passive design and its contribution to minimising the problem of poor indoor climates.&lt;br/&gt;&lt;br&gt; Through a literature review, the state of the art regarding passive strategies was assessed, the knowledge gap in this field was determined, and the tools suitable for carrying out these studies were identified. By means of simulations, the results of simulations demonstrated that thermal comfort in buildings could be significantly improved by using existing and proposed strategies for passive design. No electricity would be required for electrical devices as the indoor environment would be sufficiently comfortable. &lt;br/&gt;&lt;br&gt; Apart from building orientation, other strategies for passive design could be applied to existing or new buildings, at a low cost and without affecting the aesthetics of the buildings too much. Passive design strategies also could be applied to existing buildings that are not optimally oriented, but at a slightly higher cost than that associated with buildings with an optimum orientation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/71f4cbd5-4ac7-45db-889b-f630238d2020</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Buildings</topic> <topic>Sustainability</topic> <topic>Energy Efficiency</topic> <topic>Passive Design</topic> <topic>Orientation</topic> <topic>Shading</topic> <topic>Ventilation</topic> <topic>Materials</topic> <topic>Temperatures</topic> <topic>Thermal Comfort</topic> <topic>Simulations</topic> <topic>Retrofitting</topic> <topic>Hot Humid Regions.</topic> </subject> <subject authority="lup"> <topic>Construction Management</topic> </subject> <relatedItem type="host"> <titleInfo> <title>ISRNLUTVDG/TVBP-14/1039-SE</title> </titleInfo> <identifier type="issn">1651-0380</identifier> <identifier type="oldLupId">4780499</identifier> <part> <extent unit="pages"> <total>219</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-12-16T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>71f4cbd5-4ac7-45db-889b-f630238d2020</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:52:59+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:52:59+02:00</recordDateApproved> </recordInfo> </mods>

However, sometimes the communication of musical issues between musicians may be experienced as aggravating. In educational contexts in a broad sense, it might be advantageous if this communication could be facilitated, for example, by using visual illustrations as a complement to the verbal language. The final aim of the present PhD project is to introduce a further investigation of the relationship between what musicians do when performing classical compositions and how the music will be experienced by listeners familiar with this kind of music. As an indispensable preparative step for this purpose, based on established conventions of melody phrasing, two special visual tools were developed: the Melody Phrasing Curve and a system for notating metrical points of gravity. In two empirical studies, the relevancy of these visual tools, intended to simplify the communication of matters linked to musical interpretation, was tested. This purpose includes the exploration of musical thoughts coming up when the tools are employed by professional musicians as instruments for illustrating their musical experiences.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The Melody Phrasing Curve is a continuous line that is drawn by free hand into a special device indicating approximately the experienced dynamical fluctuations within the melody part of a composition. In the two phases of Study A, this phrasing curve was tested from the perspective of music professors listening to classical piano excerpts recorded on audio tape. The results indicate that the visual tool mentioned might be used as an instrument for illustrating the experienced changing dynamics of the melody part, primarily in piano music of a clear homophonic character.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the consecutive Study B, the other visual tool, the system for notating metrical points of gravity, was introduced. This tool was used by four professional musicians, together with the Melody Phrasing Curve, as an aid when preparing performances of three classical piano excerpts, as well as for the purpose of visually illustrating musical aspects of their recorded performances. The study included in-depth-interviews revealing some of the participants’ musical ideas.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The results revealed that the participants respected the traditions of classical music, but they were also interested in further exploring the expressive potential of the music, in order to find new interpretative solutions. Moreover, the results indicate that the visual tools employed might be used in educational contexts as triggers for activating musicians’ self-reflection and for developing a bigger awareness when interpreting classical music. Aside from the participants’ diverging drawing styles, the results further support the functionality of the Melody Phrasing Curve as a visual tool for mirroring the experienced dynamical progression of the melody part. Finally, the phrasing curve may be used for the purpose of planning musical interpretations, as well as for illustrating a given performance.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/409b8013-dcc3-4a6e-84c0-42a96f47b9cd</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Fridell_avh2.pdf">https://portal.research.lu.se/files/3027158/1502560.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8930007</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Malmö Academy of Music, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>communication of musical issues</topic> <topic>visual tools</topic> <topic>perceived dynamics</topic> <topic>melody phrasing</topic> <topic>points of gravity</topic> <topic>visual illustrations</topic> <topic>musical experiences</topic> <topic>Musical interpretation</topic> </subject> <subject authority="lup"> <topic>Music</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Studies in Music and Music Education</title> </titleInfo> <identifier type="issn">1404-6539</identifier> <identifier type="isbn">978-91-976053-5-9</identifier> <identifier type="oldLupId">1389451</identifier> <part> <detail type="volume"> <number>13</number> </detail> <extent unit="pages"> <total>266</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-27T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>409b8013-dcc3-4a6e-84c0-42a96f47b9cd</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:02+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:02+02:00</recordDateApproved> </recordInfo> </mods>

Such light sources are employed for a variety of applications within imaging, attosecond spectroscopy, and high-precision frequency metrology. However, the rather low efficiency of the HHG process, which implies a limited pulse energy and repetition rate, places restrictions on many applications.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis, the scaling of different parameters controlling the generation conditions for HHG in gases is analyzed. A general scaling model is developed, which allows scaling of the pulse energy and repetition rate of attosecond sources over many orders of magnitude, while maintaining temporal and spatial pulse characteristics. The scaling model is applied to different attosecond beam lines, which were developed and built as part of this thesis work. This includes a high-repetition rate (200\,kHz) beam line used for photoelectron emission microscopy applications, and an intense harmonic beam line delivering pulses with up to 3 µJ in the extreme ultraviolet, which was used for coherent imaging as well as for nonlinear spectroscopy applications.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In addition, microscopic sub-cycle control mechanisms based on multi-color field synthesis are studied, as well as noncollinear generation geometries. It is shown that a noncollinear geometry can be used to angularly streak attosecond pulse trains, allowing access to single pulses within the train. This technique is of interest for attosecond pump-probe measurements as well as for isolated attosecond pulse generation inside an optical cavity, a scheme that promises attosecond pulses at unprecedented power levels and repetition rates.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; This thesis is concerned with the efficient generation of ultra-short light pulses, far beyond the visible spectral range. Such light pulses can reach durations below 100 attoseconds, where one attosecond is one billionth of a billionth of a second. Why do we want to generate such extreme light pulses? &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Our knowledge of basic processes in physics and chemistry is to a large extent based on our understanding of the microscopic world of atoms and molecules. In the macroscopic world, objects move on timescales which are easily accessible to our senses, but in the microscopic world, objects move much more rapidly. The lighter the object, the smaller the energy needed to make the object move and the shorter the time scale on which the movement happens. The movement of electrons within atoms or molecules, a fundamental process essential, for example, for chemical reactions, happens on timescales of a few femtoseconds or less (1 femtosecond = 1000 attoseconds, equal to one millionth of a billionth of a second). Measuring electron dynamics in molecules, is a first step towards the realization of a so-called molecular movie, a movie that would allow us to see electronic and structural processes as they take place in chemical reactions. What kind of tools do we need to monitor such processes? &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Since the early days of photography, a short flash of light or a short exposure time in a photographic camera has allowed us to freeze the motion of an object in time. The first time-resolved ``measurements&apos;&apos; allowed to monitor the motion of a galloping horse. Ultrashort laser pulses provide similar access to dynamics which happen on time scales, which are approximately twelve orders of magnitude shorter. The time resolution is thereby determined by the temporal length of the laser pulse. Nowadays such pulses can reach a duration of a few femtoseconds. Approaching the attosecond regime is possible via a process called high-order harmonic generation. This process allows us to convert a fraction of the energy of a short laser pulse from the visible spectral range (or close to it) into wavelengths approaching the X-ray regime. During this light-conversion process, a train of attosecond pulses is formed. Today, twenty-seven years after the discovery of high-order harmonic generation, extreme light sources based on this technique are used in many laboratories. Their usability is, however, still quite limited, mainly due to the fact that the generated attosecond light pulses are very weak. Also, an ideal attosecond experiment demands single attosecond pulses instead of trains of many pulses. Both of these issues are addressed in this thesis. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; While the first high-order harmonics generated contained only a very small fraction of the energy of the generating laser pulse, modern attosecond sources reach approximately one million times higher values but still only a hundred thousandth part of the laser pulse energy. Such efficiencies are usually achieved with high-power laser systems. In this thesis, a general scaling model is developed and applied for several attosecond beam lines: at the Lund Laser Center (Sweden), at the University of Marburg (Germany), and for the development of an attosecond beam line for the European Extreme Light Infrastructure facility ELI-ALPS in Hungary. The model explains how the pulse energy of attosecond pulses can be scaled over many orders of magnitude while maintaining identical pulse characteristics. In particular, it is shown that efficient attosecond pulse generation is possible even with weak laser pulses, which enables the generation of many pulses per second, an essential requirement for many spectroscopy applications. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In addition, a new technique is developed in this thesis, allowing the efficient isolation of a single attosecond pulse from the generated pulse train. The technique promises to be applicable to attosecond pulse generation directly inside a so-called optical cavity, a resonator in which laser pulses can be trapped. Such an approach should allow the generation of isolated attosecond pulses at unprecedented power levels and repetition rates. When generated this way, attosecond pulses have another remarkable property: they form a frequency comb in the extreme ultraviolet, which can be used as a high-precision frequency ruler, promising new possibilities for extremely precise definitions of frequency and time.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Denna avhandling behandlar den effektiva genereringen av korta ljuspulser som har mycket kortare våglängder än synligt ljus. Dessa ljuspulser kan vara kortare än 100 attosekunder. En attosekund är en miljarddels miljarddel av en sekund. Men varför vill vi genera så korta ljuspulser?&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Kunskapen om fundamentala processer inom fysik och kemi baserar sig i stor utsträckning på förståelsen av den mikroskopiska världen av atomer och molekyler. I den makroskopiska världen rör sig föremålen på tidsskalor som är lätta att uppfatta för för våra sinnen, medan i den mikroskopiska världen rör sig objekten mycket snabbare. Ju lättare objektet är, desto mindre är den energi som krävs för att sätta objektet i rörelse och desto kortare är rörelsens tidskala. Elektronernas rörelse inom atomer och molekyler är en fundamental process som är väsentlig till exempel för kemiska reaktioner och som sker på tidsskalor så korta som några femtosekunder (1 femtosekund = 1000 attosekunder, lika med en miljondels miljarddel av en sekund) eller ännu kortare. Att mäta elektronernas dynamik i molekyler är det första steget till en molekylfilm, en film som visar elektroniska och strukturella processer i kemiska reaktioner. Vilka verktyg behövs för att observera sådana processer?&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sedan fotografins barndom har en kort ljusblixt eller en kort exponeringstid möjliggjort att frysa ett objekts rörelse. Genom de första tidsupplösta mätningarna kunde man mäta en galopperande hästs rörelsemöster. På samma sätt tillåter korta laserpulser att mäta dynamiska processer som äger rum på tidskalor som är 12 storleksordningar kortare. Tidsuplösningen begränsas av laserpulsens längd. Idag kan sådana laserpulser vara några femtosekunder korta. Att nå attosekundstidsskalan är möjligt genom en process som kallas för hög övertonsgenerering. Processen möjliggör konvertering av en liten del av laserpulsernas energi från det synliga (eller nära det synliga) området till våglängder som nå ända in i röntgenomradet. I denna ljuskonverteringsprocess skapas ett så kallat tåg av attosekundspulser. Idag, 27 år efter upptäckten av övertongenereringsprocessen, används extrema ljuskällor som är baserade på övertonsgenerering i många laboratorier. Tillämpbarheten är dock begränsad, framför allt för att attosekundspulser är mycket svaga. Dessutom kräver det perfekta attosekundsexperiment isolerade attosekundspulser istället för ett pulståg. Både frågorna behandlas i denna avhandling. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De första höga övertoner som producerades innehöll bara en väldigt liten del av laserpulsens energi. Däremot kan moderna attosekundspulskällor, baserad på högeffektslasersystem, nå miljoner gånger högre värden men ändå bara en hundratusendel av laserpulsens energi. I denna avhandling utvecklas en allmän skalningsmodel som tillämps på olika attosekundspulskällor, vid såväl Lunds Laser Centrum, som vid Universitetet i Marburg (Tyskland) och för utvecklingen av en attosekundspulskälla vid den europeiska anläggningen ELI-ALPS i Ungern. Modellen förklarar hur attosekundspulsernas energi kan skalas över många storlekordningar utan att påverka pulsernas egenskaper. Således påvisas att en effektiv attosekundspulsgenerering är möjlig även med svaga laserpulser som möjliggör generering av många pulser per sekund. Detta är en viktig förutsättning för många spektroskopiapplikationer. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I denna avhandling utvecklas dessutom en ny teknik för att isolera en enkild puls från attosekundspulståget. Denna teknik utlovar tillämpbarhet av attosekundsgenereringen i en optisk kavitet, en resonator som hållar laserpulser fångade. Att producera isolerade attosekundpulsar i en sådan resonator tillåter mycket högre genomsnittlig effekt och mycket högre repetitionshastighet. Men attosekundspulser som genereras i en optisk kavitet har ytterligare en anmärkningsvärd egenskap: de ger upphov till en frekvenskam i det extremt ultravioletta området. En sådan frekvenskam kan användas som en mycket exakt linjal för frekvenser och utlovar nya möjligheter för definitionen av frekvens och tid.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;b&gt;Popular Abstract in German&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Diese Arbeit behandelt die effiziente Erzeugung von ultrakurzen Lichtpulsen, deren Wellenlängen viel kürzer sind als die des sichtbaren Lichts. Solche Lichtpulse können kürzer sein als 100 Attosekunden. Eine Attosekunde hat eine Dauer von einem Milliardstel eines Milliardstels einer Sekunde. Warum wollen wir solche Lichtpulse erzeugen?&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Unser Wissen über fundamentale Prozesse in Physik und Chemie basiert weitgehend auf dem Verständnis der mikroskopischen Welt aus Atomen und Molekülen. In der makroskopischen Welt bewegen sich Objekte auf Zeitskalen, die für unsere Sinne leicht erfassbar sind. In der mikroskopischen Welt hingegen bewegen sich die Objekte sehr viel schneller. Je leichter ein Objekt, desto weniger Energie wird benötigt um das Objekt in Bewegung zu setzen und desto kürzer ist die Zeitskala auf der die Bewegung abläuft. Die Bewegung von Elektronen innerhalb von Atomen und Molekülen, zum Beispiel, ist ein fundamentaler Prozess, der entscheidend ist für chemische Reaktionen und der auf Zeitskalen von einigen Femtosekunden (1 Femtosekunde = 1000 Attosekunden, ein Millionstel eines Milliardstels einer Sekunde) oder schneller abläuft. Die Elektronendynamiken in Molekülen zu messen, ist ein erster Schritt zur Realisierung eines &quot;Molekülfilms&quot; der eletronische Vorgänge und strukturelle Umwandlungsprozesse in chemischen Reaktionen zeitaufgelöst abbildet. Welche Werkzeuge werden benötigt, um solche Prozesse sichtbar zu machen? &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Seit dem Anfang der Fotografie werden kurze Lichtblitze oder kurze Belichtungszeiten dazu eingesetzt, schnelle Bewegungsabläufe abzubilden. Die ersten solcher zeitaufgelösten Messungen machten es möglich, den Bewegungsablauf eines galoppierenden Pferdes zu studieren. Auf vergleichbare Weise erlauben kurze Laserpulse die Messung dynamischer Prozesse, die sich auf Zeitskalen abspielen, die 12 Größenordnungen kleiner sind. Die erreichbare Zeitauflösung wird dabei von der Länge des Laserpulses bestimmt. Heutzutage ist es möglich, Laserpulse mit einer Länge von wenigen Femtosekunden zu erzeugen. Attosekundenzeitskalen können durch die Erzeugung von sogenannten Höheren Harmonischen erreicht werden. Dieser Prozess erlaubt die Konvertierung eines geringen Teils der Laserpulsenergie aus dem sichtbaren (oder nahe dem sichtbaren) Spektralbereich zu kurzen Wellenlängen, die den Röntgenbereich erreichen können. In diesem Lichtumwandlungsprozess wird ein sogenannter Pulszug, das heißt mehrere aufeinanderfolgende Attosekundenpulse, erzeugt. Heutzutage, 27 Jahre nach der Entdeckung des Harmonischenerzeugungsprozesses, werden Lichtquellen, die auf diesem Prozess basieren, in vielen Laboren eingesetzt. Die Verwendbarkeit der erzeugten Pulse ist allerdings eingeschränkt, vor allem aufgrund der sehr niedrigen Pulsenergien. Außerdem werden für ein ideales Attosekundenexperiment einzelne Laserpulse an Stelle eines Pulszuges benötigt. Beide Aspekte werden in dieser Arbeit behandelt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Die ersten höheren Harmonischen enthielten nur einen verschwindend kleinen Teil der aufgewendeten Laserpulsenergie. Moderne Attosekundenpulsequellen, meist auf Hochleistungslasern basierend, können dagegen millionenfach höhere Werte und damit etwa ein Hunderttausendstel der Laserpulsenergie erreichen. In dieser Arbeit wird ein allgemeines Skalierungsmodell entwickelt und auf verschiedene Attosekundenquellen am Laserzentrum in Lund (Schweden) sowie an der Universität Marburg als auch für die Entwicklung einer Attosekundenpulsquelle für die europäischen Forschunganlage ELI-ALPS in Ungarn, angewendet. Das Modell erklärt, wie die Energie der Attosekundenpulse über viele Größenordnungen skaliert werden kann, ohne weitere Pulseigenschaften zu ändern. Dadurch wird insbesondere gezeigt, dass die effektive Erzeugung von Attosekundenpulsen auch mit relativ schwachen Laserpulsen möglich ist. Das bedeutet, dass viele Pulse per Sekunde erzeugt werden können, was eine Voraussetzung für viele Spektroskopieanwendungen ist. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In dieser Arbeit wird außerdem eine neue Methode zur Isolierung einzelner Pulse aus dem Pulszug entwickelt. Die Methode sollte sich zur Erzeugung einzelner Attosekundenpulse in einem optischem Resonator eignen. Einzelne Attosekundenpulse in einem Resonator zu erzeugen, ermöglicht viel höhere mittlere Leistungen und Repetitionsraten. Außerdem haben Attosekundenpulse, die in einem Resonator erzeugt werden, eine weitere einzigartige Eigenschaft: Sie bilden einen Frequenzkamm im extremen ultravioletten Spektralbereich. Ein solcher Frequenzkamm kann als sehr exaktes &quot;Lineal&quot; zur Frequenzmessung verwendet werden und verspricht neue Möglichkeiten für die Definition von Frequenz und Zeit.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/fc34da91-a11c-4d96-9ff9-59b194ad8981</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Heyl2014PhD_pdf.pdf">https://portal.research.lu.se/files/3028441/4937902.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">51160767</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Atomic Physics, Department of Physics, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Coherent imaging</topic> <topic>Ultrafast electron dynamics</topic> <topic>Single attosecond pulses</topic> <topic>Attosecond pulse trains</topic> <topic>XUV sources</topic> <topic>High-order harmonic generation</topic> <topic>XUV frequency combs</topic> <topic>Fysicumarkivet A:2014:Heyl</topic> </subject> <subject authority="lup"> <topic>Atom and Molecular Physics and Optics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>LRAP 496 (2014)</title> </titleInfo> <identifier type="issn">0281-2762</identifier> <identifier type="isbn">978-91-7623-158-6</identifier> <identifier type="oldLupId">4779571</identifier> <part> <extent unit="pages"> <total>263</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-12-12T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>fc34da91-a11c-4d96-9ff9-59b194ad8981</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:05+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:05+02:00</recordDateApproved> </recordInfo> </mods>

The aim of this thesis was to examine the occurrence of asthma, symptoms and mechanism of bleaching-associated nasal symptoms, the effects on HRQoL and how young hairdressers reason about the work environment. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A moderate increased risk of asthma was found during active time in non-smoking hairdressers, and it was somewhat greater for those performing most bleaches and hair spraying. Childhood hay fever and smoking had no effect on this risk. Hairdressers with bleaching- associated nasal symptoms (S+) responded in a challenge study with increasing symptoms and albumin in nasal lavage at a nasal challenge with persulphate, and atopic females to a lesser intent. The reaction of the S+ did not seem to be IgE-mediated. After a month&apos;s work S+ reacted with increasing symptoms and an increase in ECP in nasal lavage. HRQoL decreased in S+ parallel to an increase in nasal symptoms. In an interview study young hairdressers had an awareness of the work environment and opportunities to influence it, but shortage of means and strategies made it not an active part of their business. Focus was on customers and working technique. Organization had an impact and teachers were crucial for the preventive work. Hairdressers saw the professional future as uncertain due to work-related health risks and their consequences.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Frisöryrket har en lång historia av stolta yrkesutövare, men frisörer arbetar i en komplex arbetsmiljö, där de utsätts för olika risker, inte bara luftvägsbesvär, utan även handeksem, muskelrelaterade besvär, stress, och ögonbesvär. I Sverige är 85 - 90 % av frisörerna kvinnor, varav de flesta är egenföretagare antingen som ensamägare till en salong eller tillsammans med flera frisörer med hyrstolar och anställda. År 2010 fanns 20 300 frisörer, varav 14 600 egenföretagare och 2011 var frisör det vanligaste yrket bland kvinnliga egenföretagare i Sverige. &lt;br/&gt;&lt;br&gt; I denna avhandling ingår fyra studier om kvinnliga frisörer med olika upplägg; Studie I var en korhortstudie där vi via frågeformulär studerade insjuknande i astma hos kvinnliga frisörer i Sverige jämfört med kvinnor i den allmänna befolkningen. I Studie II gjordes en provokation av nässlemhinnan med kaliumpersulfat, ett ämne som ingår i blekmedel, hos frisörer med näsbesvär främst orsakade av blekmedel, och reaktionerna jämfördes med reaktionerna hos frisörer utan näsbesvär och hos allergiker. Studie III var en dagboksstudie där vi följde hur luftvägsbesvär förändrades hos frisörer med blekmedelsutlösta näsbesvär under en arbetsmånad efter minst två veckors semester och jämförde besvären hos besvärsfria frisörer och pollenallergiska kvinnor under pollen-säsongen. Vi jämförde även deras hälsorelaterade livskvalitet. I Studie IV intervjuades unga nyutbildade frisörer tre till fyra år efter examen om deras syn på sin arbetsmiljö och om hur de kan påverka denna, hur de kan omsätta sina arbetsmiljökunskaper från utbildningen och hur de ser på sin framtid i yrket.&lt;br/&gt;&lt;br&gt; I Studie I fann vi en måttligt ökad risk att under aktiv tid som icke-rökande frisör insjukna i astma jämfört med den allmänna befolkningen. Risken var till viss del större för de frisörer som utförde mest blekningar och använde mest hårspray. Atopi påverkade inte risken att få astma av frisörarbete. &lt;br/&gt;&lt;br&gt; I Studie II fann vi att frisörer med blekmedelsutlösta näsbesvär reagerade med ökande besvär vid en provokation av nässlemhinnan med kaliumpersulfat, och även med en ökad mängd albumin i nässköljvätska. Frisörerna utan näsbesvär reagerade inte, medan atopikerna reagerade till viss mån. Frisörernas reaktion verkade vara ospecifik.&lt;br/&gt;&lt;br&gt; I Studie III reagerade frisörer med blekmedelsutlösta näsbesvär med ökande besvär parallellt med en sjunkande livskvalitet under en månads arbete. Det fanns även tecken på en ökad inflammatorisk process i nässlemhinnan, men inte på en ökad reaktivitet i nässlemhinnan mot kaliumpersulfat. Livskvaliteten hos de symptomatiska frisörerna sjönk, men pollenallergikerna påverkades mer. De friska frisörerna hade en tendens att öka i livskvalitet under en månads arbete.&lt;br/&gt;&lt;br&gt; I Studie IV fann vi en medvetenhet hos de unga frisörerna om arbetsmiljön och om möjligheter att påverka den, men det saknades brist på medel och strategier för att göra det till en aktiv del av sin frisörverksamhet. Fokus var på kunderna och arbetstekniken, och olika besvär ändrade inte på detta. Lärarna hade en avgörande roll för intresset för preventiva arbetsmiljöåtgärder. Organisationen och finansiella frågor kunde negativt påverka det förebyggande arbetsmiljöarbetet. Frisörerna såg yrket med dess för- och nackdelar, och framtiden som osäker pga de arbets-relaterade hälsoriskerna. &lt;br/&gt;&lt;br&gt; För att kunna råda unga personer som vill bli frisörer behövs mer forskning för att förstå varför vissa frisörer utvecklar luftvägsbesvär mot hårkemikalier, och hur dessa besvär påverkar frisörerna i arbetet och på fritiden. Vi behöver också förstå vilka specifika ämnen i hårkemikalierna, och i vilka doser, de framkallar besvär och varför frisörerna tidigt lämnar sitt yrke.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c494d28c-a724-4197-8825-0a738d2a2017</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Female_hairdressers.pdf">https://portal.research.lu.se/files/3028611/4354035.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2350561</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Occupational and Environmental Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Female hairdressers</topic> <topic>Respiratory symptoms</topic> <topic>Health-Related Quality of Life</topic> <topic>Work environment</topic> </subject> <subject authority="lup"> <topic>Occupational Health and Environmental Health</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-61-8</identifier> <identifier type="oldLupId">4353400</identifier> <part> <detail type="volume"> <number>2014:36</number> </detail> <extent unit="pages"> <total>110</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-04-04T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>c494d28c-a724-4197-8825-0a738d2a2017</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:06+02:00</recordDateApproved> </recordInfo> </mods>

Recent publications, however, have reported stable or even decreasing hip fracture incidence. No reports evaluate whether these changes in hip fracture incidence are associated with changes in bone mineral density (BMD), if they apply in both urban and rural settings, and few have tried to analyze whether they are attributable to cohort and/or period effects.&lt;br/&gt;&lt;br&gt; In population-based samples of urban and rural women (n=437, age ≥50 years) and men (n=277, age ≥60 years) risk factors for hip fracture were evaluated in 1988/89 and 1998/99 as was BMD in Malmö women from 1970 to 1999 (n=459, age ≥50 years). The annual number of hip fractures in the respective region, gender and age group as well as nationwide in all individuals aged ≥50 years were obtained from central national inpatient data from 1987 to 2002 and in Malmö women from 1967 to 2001 by local records. Age-Period-Cohort (APC) effects were evaluated by log likelihood estimates in Poisson regression models.&lt;br/&gt;&lt;br&gt; In all local cohorts the age-standardized hip fracture incidence was stable from 1987 to 2002 and from 1969 to 2001, and BMD and prevalence of osteoporosis were stable between 1974 and 1999 and between 1988/89 and 1998/99. In nationwide Swedish data hip fracture incidence was stable from 1987 to 1996, after which a decrease was evident. There were evident period+cohort effects in women, with a major reduction in hip fracture incidence by subsequent birth cohorts (estimated incidence rate ratio 2.2 comparing women born 1889–96 to women born 1945–52). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis infers that the hip fracture incidence has levelled off also in Sweden and has since the mid 1990s been replaced by a decreasing annual incidence. In women this appear to be the result of cohort+period effects, in that that those born more recently had a lower incidence than those born earlier. As no differences in BMD or prevalence of osteoporosis were apparent, the changes in hip fracture incidence seem attributable to other factors, probably linked to the major changes in society during the century-long lifespan of the examined individuals. The data presented in this thesis are important both for projecting future hip fracture burden and when planning for hip fracture resources in the future.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/42de8e9c-23db-4cd7-ad95-84e55bb142b8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_LU_uppladdning.pdf">https://portal.research.lu.se/files/3029049/1567429.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">304388</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>APC-model</topic> <topic>epidemiology</topic> <topic>Hip fracture</topic> <topic>osteoporosis</topic> <topic>trends</topic> <topic>risk factors</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-39-9</identifier> <identifier type="oldLupId">1567383</identifier> <part> <detail type="volume"> <number>2010:25</number> </detail> <extent unit="pages"> <total>131</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-04-09T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>42de8e9c-23db-4cd7-ad95-84e55bb142b8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:11+02:00</recordDateApproved> </recordInfo> </mods>

To evaluate their respective suitability, the geological history of the bedrock in these two areas has been investigated. This study has focused on the thermal evolution, from c. 500 °C to c. 50 °C. 40Ar-39Ar geochronology on hornblende, muscovite and biotite, was applied to determine cooling from c. 500 °C to c. 300 °C, whereas apatite fission-track (AFT) and (U-Th)/He thermochronology were used to determine the thermal evolution between c. 120 °C and c. 50 °C.&lt;br/&gt;&lt;br&gt; The crystalline bedrock in the Forsmark area consists of c. 1.89-1.85 Ga meta-igneous rocks that form part of the Svecofennian orogen. 40Ar-39Ar muscovite ages indicate cooling through c. 350 °C between 1.76 and 1.71 Ga. Biotite ages from surface samples suggest that the present erosion surface cooled below c. 300 °C at 1.73-1.66 Ga. The results show that the area has remained at temperatures below 300 °C since c. 1.7 Ga. The cooling of the Forsmark area reflects either slow cooling after the tectonothermal activity during the Svecofennian orogeny, or uplift in response to far-field effects of 1.7 Ga orogenic activity further to the west (or a combination of these processes).&lt;br/&gt;&lt;br&gt; The 1.80 Ga rocks at Oskarshamn belong to the Transscandinavian Igneous Belt (TIB). Younger, 1.45 Ga granites and c. 0.95 Ga dolerite dykes are also present in the area. 40Ar-39Ar hornblende ages indicate initial rapid cooling down to c. 500 °C after the emplacement of TIB rocks. Subsequent cooling through c. 300 °C initially occurred at 1.6 Ga (40Ar-39Ar biotite ages). A 1.51-1-47 Ga 40Ar-39Ar biotite age group reflects either incomplete resetting by younger granitic intrusions in the area or thermal activity related to either the youngest manifestations of rapakivi intrusions or to the initiation of the Danopolonian event in the south. A 1.43-1.42 Ga biotite age group represents cooling after intrusion of the c. 1.45 Ga granites. &lt;br/&gt;&lt;br&gt; The (U-Th)/He and AFT data were obtained from borehole and surface samples. Although the uncorrected (U-Th)/He and the AFT borehole ages at Oskarshamn are identical, and similar age/depth trends from the two thermochronometers are present at Forsmark, the (U-Th)/He ages are older (or AFT ages younger) than expected with respect to the closure temperatures of the two systems. The systematic age shift may be controlled by α-recoil damage of the (U-Th)/He system in U-rich apatite, possibly in combination with radiation-enhanced track annealing in the AFT system, and by invalid FT-correction of the (U-Th)/He system due to a heterogeneous distribution of U in apatite. &lt;br/&gt;&lt;br&gt; Thermal modelling of the AFT ages reveals similar thermal histories in the two areas. Complete track annealing indicates that the present ground surface was situated at a depth of &amp;gt;4 km prior to c. 200 Ma. Subsequent uplift started between Late Palaeozoic and Early Mesozoic time and waned c. 100 Ma ago. Uplift may have been related to transtensional tectonics in southernmost Sweden and/or extensive volcanic activity to the south and west. After the modification in the uplift rate, continued exhumation was considerably slower.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/eb0cf89f-c494-4d0e-88e7-9b9ab5786b00</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa.pdf">https://portal.research.lu.se/files/3029953/1050048.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2114181</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Geology, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>40Ar-39Ar</topic> <topic>Fennoscandian Shield</topic> <topic>(U-Th)/He</topic> <topic>AFT</topic> <topic>geochronology</topic> <topic>thermochronology</topic> <topic>cooling</topic> <topic>uplift</topic> </subject> <subject authority="lup"> <topic>Geology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Litholund theses</title> </titleInfo> <identifier type="issn">1651-6648</identifier> <identifier type="issn">1651-6648</identifier> <identifier type="oldLupId">1049939</identifier> <part> <detail type="issue"> <number>16</number> </detail> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-04-24T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>eb0cf89f-c494-4d0e-88e7-9b9ab5786b00</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:20+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:20+02:00</recordDateApproved> </recordInfo> </mods>

There is a strong correlation between long-standing inflammatory bowel disease where these pro-inflammatory mediators are abundant and colorectal cancer. We have shown that LTD4 via its receptor CysLT1 induces expression of proteins associated with colorectal cancer and promotes proliferation, survival and migration in intestinal epithelial cells. In addition, we have demonstrated that that high expression of CysLT1R in colorectal adenocarcinomas predicts poor prognosis in patients.&lt;br/&gt;&lt;br&gt; In the presented papers in this thesis we investigated the role of CysLT1R in different mouse models of colorectal cancer. In the mouse xenograft model of colon cancer, we were able to observe a reduced tumor growth in response to CysLT1R antagonist treatment. The inhibition of the tumor growth was accompanied with changes in proliferation and apoptosis as determined by reduced Ki-67 expression, increased expression of p21WAF/Cip1, cleaved caspase 3 and caspase-cleaved keratin 18. An impaired tumor angiogenesis was also demonstrated by detection of increased levels of VEGF and reduced vessel size. We also investigated the role of CysLT1R in 1) FAP/sporadic colorectal cancer by crossing ApcMin/+ mice with mice lacking CysLT1R expression and in 2) colitis-associated colorectal cancer by employing the AOM/DSS-model on mice lacking CysLT1R expression. Interestingly, a reduced polyp formation in a gender-specific manner could be observed in both models. CysLT1R knockout female mice, but not male mice exhibited a reduced polyp formation in the small intestine and colon, respectively. Also, a decreased nuclear expression of β-catenin within the epithelial tumor compartment was determined for CysLT1R mutant female mice in both models. However, the mechanism of tumor progression in FAP/sporadic colorectal cancer and in colitis-associated colorectal cancer might differ as indicated by reduced tumor expression of COX-2 and reduced serum levels of PGE2 in the female double mutant (CysLT1R−/− ApcMin/+) mice, whereas AOM/DSS-treated female single mutant (CysLT1R−/−) mice demonstrated increased serum levels of PGE2. In conclusion, the presented mouse models of colorectal cancer further strengthen our previous in vitro findings and highlight the prospect of CysLT1R as an alternative therapeutic approach.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Det finns ett starkt samband mellan kronisk inflammation och cancer. Ett av de mer etablerade sambanden är den mellan kronisk inflammation i tarmen och den i Sverige tredje vanligaste cancersjukdomen, nämligen tjocktarmscancer. Risken för tjocktarmscancer korrelerar med inflammationsutbredning, varaktighet och svårighetsgrad. Den inflammatoriska processen regleras av rekryterade immunologiska celler och berörd vävnad huvudsakligen via olika signaleringsmolekyler såsom leukotriener. Dessa molekyler är pro-inflammatoriska och bidrar bland annat till vätskeansamling i samband med en inflammatorisk process. De bidrar också till muskelsammandragningar och är patologiskt förknippade i det avseendet med andningssvårigheter vid astma. Leukotriener förmedlar sin effekt via inbindning till specifika cellmottagare, s.k. receptorer. Det mest potenta leukotrienet är cysteinyl leukotriene D4 (LTD4) och medlar främst via receptorn cysteinyl leukotriene 1 (CysLT1R). Vår forskningsgrupp har tidigare funnit att patienter med koloncancer (Dukes B typ) som har ett högt tumörvävnadsuttryck av CysLT1R har sämre överlevnadsprognos jämfört med patienter med lågt uttryck. Vi har också upptäckt att en närbesläktad receptor (CysLT2R) som också finns i tumörer men har uppvisat motsatt effekt på tumörceller och därmed positiv effekt för patienten. Vi har tidigare också i cellkulturer med olika koloncancer cellinjer sett att LTD4 via CysLT1R ger en ökad cellöverlevnad och vandringsförmåga, s.k. migration som är en förutsättning för metastasering, d.v.s. spridning till andra vävnader och etablering av sekundära tumörer. Däremot har cysteinyl leukotriene-inducerad CysLT2R signalering påvisat celldifferentiering, något som förknippas med cellmognad, vävnadsstabilitet och integritet. Eftersom tumörbildningsförmågan beror på interaktion mellan tumörceller och omgivande celler och vävnader inte går att undersöka genom att studera enskilda celler i en cellkultur, har nästa givna steg varit att utföra djurstudier. &lt;br/&gt;&lt;br&gt; Jag har i mina avhandlingsarbeten undersökt betydelsen av CysLT1R i olika djurmodeller för tjocktarmscancer. Vi har kunnat visa att behandling av subkutana humana koloncancerceller med substanser som specifikt binder till CysLT1R och förhindrar dess aktivitet, s.k. antagonister ger reducerad tumör tillväxt i möss med bristfälligt cellulär immunsystem. Detta åtföljdes av en minskad celldelning och kärlbildning i tumörerna samt ökad celldöd. Genomisk förändring, s.k. mutation av APC-genen bärs av mellan 80-90% av alla koloncancer patienter samt är ansvarig för den familjära formen av tjocktarmscancer (familial adenomatous polyposis; FAP), d.v.s. APC-genen är en betydande faktor i den mänskliga etiologin för tjocktarmscancer. APC-genen är involverad i flera cellulära processer som reglerar celltillväxt och celldelning. För att studera betydelsen av CysLT1R i utvecklingen av tjocktarmscancer hos dessa patienter använde vi oss av ApcMin/+ musmodellen som har en mutation i Apc-genen, vilket möjligör bildandet av flera tumörer i huvudsakligen tunntarmen. Vi kunde särskilja en könsspecifik skillnad i tumörbildningen, som var direkt beroende av CysLT1R-genuttrycket. Honor som saknade uttryck av CysLT1R hade signifikant mindre antal av tumörer i tunntarmen, i jämförelse med honor som hade oförändrad CysLT1R-uttryck. Dessa möss hade också större tumörinfiltrat av vita blodceller, subtyp CD8+ T celler, något som är gynnande och överrensstämmer med tjocktarmscancer patienter och deras överlevnadsprognoser. Honor som saknade uttryck av CysLT1R hade också, förutom reducering av cysteinyl leukotriener såsom LTD4, även en minskning av prostaglandin E2 (PGE2) serumkoncentrationer. Detta är anmärkningsvärd med avseende på att PGE2, och det enzym som ansvarar för dess produktion (COX-2), har påvisats i större mängder hos patienter med tjocktarmscancer. Låga doser av aspirin (acetylsalicylsyra – ASA), som hämmar bildningen av prostaglandiner har också uppvisat en skyddande effekt mot tjocktarmscancer. För att vidare verifiera betydelsen av CysLT1R använde vi möss som saknade uttryck av CysLT1R och tillämpade ett väletablerat protokoll för kemisk inducering av kolit-associerad tjocktarmscancer. Dessa djur uppvisade samma tendenser men inte i samma utsträckning som de honmöss som också saknade uttryck av APC. Vårt resultat indikerar att CysLT1R är av betydelse för utvecklingen av tjocktarmscancer i möss, möjligtvis mer i samband med avsaknad av APC uttryck. Dessa resultat lyfter också fram möjligheterna med att påverka aktiviteten hos CysLT1R som alternativ terapeutiskt mål vid behandling av patienter med tjocktarmscancer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a9c231d2-fd90-4c4f-9ac3-8f84cce546cd</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="The_role_of_CysLT1R_in_mouse_models_of_colorectal_cancer.pdf">https://portal.research.lu.se/files/3030418/4447038.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8025420</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Cell Pathology</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-011-1</identifier> <identifier type="oldLupId">4447032</identifier> <part> <detail type="volume"> <number>2014:82</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-13T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>a9c231d2-fd90-4c4f-9ac3-8f84cce546cd</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:24+02:00</recordDateApproved> </recordInfo> </mods>

SNARE-proteins are crucial for the fusion of insulin granules with the plasma membrane, a prerequisite for insulin secretion. The aim of this thesis has been to investigate the exocytotic process in β-cells with a specific focus on the function and significance of the two SNARE-proteins SNAP-25 and syntaxin 1.&lt;br/&gt;&lt;br&gt; SNAP-25 and syntaxin 1 was discovered to be situated in clusters along the plasma membrane. Immunoneutralization of syntaxin 1 and SNAP-25 resulted in a strongly reduced exocytotic response of primed granules in close association with the voltage-dependent calcium channels.&lt;br/&gt;&lt;br&gt; Cholesterol is an essential component of the plasma membrane. Desorption of cholesterol from the plasma membrane in β-cells were accompanied with an overall reduction in the response of β-cells, from insulin secretion to exocytosis. We believe this is due to disturbance of a basic mechanism. Indeed, we found that SNAP-25 migrated from the plasma membrane out to the cytosol.&lt;br/&gt;&lt;br&gt; The stimulating effect of cAMP on insulin secretion is implemented through different pathways. One pathway is through cAMP-GEFII and its downstream affector RIM2. We show that SNAP-25 binds to both cAMP-GEFII and RIM2, and that this binding mediates the effects of cAMP on exocytosis.&lt;br/&gt;&lt;br&gt; The blind-drunk mouse carries a mutation in SNAP-25 that results in increased binding affinities within the SNARE-complex and the consequence in pancreatic β-cells are impaired vesicle recycling and granule exocytosis.&lt;br/&gt;&lt;br&gt; These results together demonstrate the significance of a functional exocytotic machinery for β-cells to respond satisfying to an elevation in blood glucose.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/470cb063-6c13-4dab-8e31-cc5b22231a04</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>calcium channel</topic> <topic>cAMP</topic> <topic>syntaxin 1</topic> <topic>SNAP-25</topic> <topic>SNARE</topic> <topic>exocytosis</topic> <topic>Insulin secretion</topic> <topic>pancreatic beta-cells</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-66-7</identifier> <identifier type="oldLupId">1021812</identifier> <part> <detail type="volume"> <number>2008:13</number> </detail> <extent unit="pages"> <total>114</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-02-29T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>470cb063-6c13-4dab-8e31-cc5b22231a04</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:25+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:25+02:00</recordDateApproved> </recordInfo> </mods>

The three most common skin cancers are basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and malignant melanoma (MM). A correct diagnosis is crucial for an efficient and tailored treatment for the skin cancer patient. The purpose of this thesis was to evaluate different aspects of the preoperative diagnosis of skin cancer. The studies making up this thesis were based on analysis of data from a register including all skin tumour excisions at the Department of Dermatology in Helsingborg, Sweden, from March 2008 to January 2015. The registered data included e.g. sex and age of the patient, tumour site and size, dermoscopic features of the tumour, the preliminary preoperative and final postoperative (histopathological) diagnosis as well as tumour cells at surgical margins. &lt;br/&gt;&lt;br&gt; The preliminary preoperative clinical diagnosis was compared with the final histopathological diagnosis in 2,953 excised tumours, whereof 1,626 (55.1%) were malignant, showing high diagnostic accuracy for the diagnosis of malignant tumour and for the diagnosis of basal cell carcinoma (BCC). A total of 96.0% of all excisions had tumour-free margins.&lt;br/&gt;&lt;br&gt; The number needed to excise (NNE) for melanoma (the number of pigmented lesions excised to find one melanoma) was calculated for 1,717 cases of excised skin tumours (252 melanomas, 1,395 naevi and 70 seborrhoeic keratoses (SK)). The overall NNE value during the study period was 6.5 (SKs not included). When SKs were included in the calculations the NNE was 6.8. The NNE value decreased with increasing age of the patient and varied for different body locations, with the highest values found for the trunk and the lowest for the arms. &lt;br/&gt;&lt;br&gt; When the ABCD rule of dermoscopy was used preoperatively at the bedside in 309 cases (46 melanomas and 263 naevi), use of the algorithm achieved 83% sensitivity and 45% specificity for melanoma diagnosis. A sensitivity of 74% and specificity of 91% were seen for the clinical diagnosis. A considerable percentage (19.6%) of very early melanomas were preoperatively not expected to be melanomas by the dermatologist.&lt;br/&gt;&lt;br&gt; The prediction of histopathological subtype of BCC is important for choosing optimal treatment in BCC patients and was assessed in 1,501 cases with pre- or postoperative diagnosis of BCC. The prediction of superficial BCC (sBCC) significantly improved after an educational update on dermoscopic criteria for sBCC in cases assessed by dermoscopy. &lt;br/&gt;&lt;br&gt; In conclusion, these studies have shown high accuracy of the preoperative diagnosis of malignant tumour and BCC. With increasing age of the patient, a higher rate of excised pigmented skin lesions was melanomas. Bedside use of the ABCD rule of dermoscopy achieved high sensitivity but low specificity for melanoma diagnosis; however, clinical information seemed to add to specificity. Prediction of sBCC was enhanced after a dermoscopy training session and when dermoscopy was mandatory.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Förekomsten av hudcancer ökar i ljushyade befolkningsgrupper och hudcancer tillhör de cancergrupper som ökar mest i Sverige. De tre vanligaste formerna av hudcancer är basalcellscancer, skivepitelcancer och malignt melanom. Under 2013 utgjorde skivepitelcancer och malignt melanom ca 16 % av alla cancerfall som rapporterades in till Svenska Cancerregistret; över 6 000 fall av skivepitelcancer och över 3 000 fall av malignt melanom inrapporterades. Den allra vanligaste cancern är basalcellscancer med ca 45 000 inrapporterade fall under 2013. &lt;br/&gt;&lt;br&gt; Majoriteten av hudcancerfall botas genom att tumören opereras bort. Malignt melanom är den mest maligna av de tre cancerformerna; ca 500 personer dog av sin melanomsjukdom under 2013. Dödligheten i skivepitelcancer är låg och ligger runt 50-60 fall per år. Vid båda dessa cancerformer är tidig diagnos och avlägsnande av tumören av högsta vikt och för prognosen.&lt;br/&gt;&lt;br&gt; Basalcellscancer växer lokalt aggressivt, men sprider sig inte till andra organ. De största utmaningarna när det gäller basalcellscancer är dels det stora antalet tumörer, dels att denna tumörform i ungefär hälften av fallen uppstår i ansiktet. Korrekt handläggning är därför av största vikt för gott slutresultat.&lt;br/&gt;&lt;br&gt; Den kraftiga ökningen av hudcancer märks tydligt på Sveriges hudkliniker, där hudcancer eller misstänkt hudcancer numera är en av de vanligaste besöksorsakerna. Vikten av effektiv och korrekt handläggning av hudcancerpatienter är uppenbar, både för att minska det personliga lidandet för enskilda patienter och för att sjukvårdens resurser ska kunna användas på ett så effektivt sätt som möjligt.&lt;br/&gt;&lt;br&gt; All behandling har sin utgångspunkt i en diagnos och en korrekt diagnos är en självklar förutsättning för ändamålsenlig och effektiv behandling. Diagnosen hudcancer ställs på basen av tumörens utseende, i kombination med bakgrundsinformation, såsom hur länge tumören har funnits, tillväxt eller annan förändring i utseendet, förekomst av blödning, ömhet eller klåda. Till sin hjälp i diagnostiken har dermatologen också ett speciellt handhållet mikroskop (dermatoskop) som förstorar förändringen ca 10 gånger, men också ger möjlighet att se strukturer som ligger precis under hudytan, i överhuden och i övre läderhuden. Dermatoskop utvecklades för användning i rutinbruk för undersökning av pigmenterade hudförändringar i början av 1990-talet. Värdet av dermatoskopi för att förbättra diagnostiken av melanom har visats i flera studier. På senare år har man alltmer uppmärksammat värdet av att använda dermatoskop även i undersökning av tumörer som vanligen inte är pigmenterade, såsom basalcellscancer och skivepitelcancer.&lt;br/&gt;&lt;br&gt; Den viktigaste behandlingen för de flesta hudcancerformer är operation. Alternativa behandlingsformer finns för skivepitelcancer i tidigt stadium och vissa former av basalcellscancer, särskilt den ytliga. Vid operation är det viktigt att hela tumören avlägsnas, vilka marginaler man väljer avgörs bland annat av vilken diagnos som misstänks. Den avlägsnade tumören undersöks mikroskopiskt av patolog för fastställande av diagnos och bedömning av marginaler av frisk hud, för att avgöra om tumören är fullständigt avlägsnad. Diagnosen som fastställs vid den patologiskt mikroskopiska undersökningen har i undersökningarna i denna avhandling räknats som den korrekta, dvs. den patologiskt mikroskopiska undersökningen är referensmetod. &lt;br/&gt;&lt;br&gt; Vi har studerat olika aspekter av hur korrekt diagnostiken av hudtumörer är i den kliniska vardagen. Studierna baseras på registreringar som gjorts i samband med att hudtumörer opererats bort på hudkliniken i Helsingborg under perioden mars 2008 till januari 2015. De uppgifter som registrerats är bland annat ålder och kön på patienten, storlek och kroppslokalisation samt dermatoskopiskt utseende av tumören, undersökande dermatologs preliminära huvuddiagnos (endast en diagnos, den viktigaste, har registrerats) och den slutgiltiga patologiskt mikroskopiska diagnosen. I vissa fall har ett vävnadsprov av tumören undersökts mikroskopiskt för fastställande av diagnos innan operation, dessa tumörer har inte tagits med i våra beräkningar. &lt;br/&gt;&lt;br&gt; I de analyser vi har gjort för bedömningen av om dermatologens diagnos före operation är korrekt har vi använt oss av statistiska beräkningar som brukar användas för bedömning av en diagnostisk metod jämfört med en referensmetod. De mått vi har använt är bland annat sensitivitet, specificitet och positivt prediktivt värde. Sensitivitet speglar känsligheten i metoden, dvs. hur stor andel av de som i verkligheten har en viss diagnos hittar man med sin undersökning. Specificitet å andra sidan speglar metodens förmåga att utesluta sjukdom hos de som är friska. Positivt prediktivt värde ger ett mått på hur stor andelen verkligt sjuka är, av alla de fall som man har ställt diagnosen på.&lt;br/&gt;&lt;br&gt; I det första arbetet har vi studerat hur korrekt hudcancerdiagnosen är för de tre vanligaste tumörerna genom att jämföra den preliminära diagnosen som ställts före operation med den patologiskt-mikroskopiska diagnosen. Under studieperioden som sträckte sig från mars 2008 till september 2011 inkluderades 2 953 bortopererade hudtumörer, av dessa var 55.1 % (1 626 tumörer) elakartade (maligna). Resterande tumörer var godartade (benigna); den vanligaste benigna tumören som opererats bort var pigmentnevus (964 fall). Av de maligna tumörerna var 1 180 basalcellscancer, 303 skivepitelcancer och 136 melanom. Sensitiviteten för malign tumör var hög, liksom förmågan att prediktera att tumören var malign. Den diagnostiska säkerheten för diagnosen basalcellscancer var också hög, medan korrektheten för de andra två tumörerna var något lägre. För skivepitelcancer var den vanligaste kliniska feldiagnosen basalcellscancer och för melanom var det godartat pigmentnevus (också kallat ”födelsemärke” eller ”leverfläck”). Samtliga tumörer i studien var dock bortopererade, så tumörerna missades inte, men i dessa fall var inte den korrekta diagnosen dermatologens huvuddiagnos före operation.&lt;br/&gt;&lt;br&gt; I delarbete två har vi enbart studerat diagnostiken av melanom. För melanom är, som beskrivits ovan, den viktigaste alternativdiagnosen inte en annan malign tumör, utan godartat pigmentnevus. Pigmentnevus är extremt vanligt i befolkningen, de flesta människor har ett flertal sådana förändringar, vissa personer har mer än hundra. Målet är att hitta melanom i tidigt skede då sjukdomen är botbar. I det skedet har melanomet ofta inte utvecklat alla synliga karakteristika och kan därför vara svårt att skilja från pigmentnevus. Man vill hitta och behandla melanom i tidigt skede, men samtidigt inte göra för många onödiga operationer av godartade förändringar. I denna studie har vi beräknat antalet melanom som opereras bort delat med det totala antalet pigmentförändringar (godartade och elakartade) som opereras bort. Det värde man får fram kallas Number Needed to Excise (NNE) med andra ord: antalet pigmentförändringar som opereras bort för att hitta ett melanom. Vi fann att NNE sett över hela studieperioden var 6.5. Vi såg en minskande trend i NNE under de fyra år som studien pågick, att NNE var lägre vid högre ålder på patienten (1.8 hos patienter som var äldre än 80 år) och när det gäller kroppslokalisation av tumören var NNE högst på bålen och lägst på armen.&lt;br/&gt;&lt;br&gt; I den tredje studien har vi att utvärderat en diagnostisk algoritm som har utarbetats för att förenkla diagnostiken av melanom med dermatoskop. Vi fann att användning av algoritmen gav hög sensitivitet för melanomdiagnosen (83 %) men låg specificitet (45 %), dvs. man hittade de flesta fallen av melanom men däremot var algoritmen inte lika bra på att utesluta melanom hos de som var godartade. I denna studie fick dermatologen inte bara notera sin huvuddiagnos, utan också på en 5-gradig skala skatta hur säker han/hon var på diagnosen. Vi fann då att i nästan 20 % av mikroskopiskt påvisade melanom var dermatologen relativt säker före operationen (skattat 4 på den 5-gradiga skalan) på att den mikroskopiska undersökningen inte skulle visa melanom. Samtliga dessa fall rörde sig om tumörer i ett tidigt stadium, och fyndet illustrerar att melanomdiagnosen kan vara svår, särskilt tidigt i förloppet. Alla dessa tumörer opererades dock bort, vilket visar att man ändå bedömt dem som misstänkta och de missades därför inte. &lt;br/&gt;&lt;br&gt; Basalcellscancer förekommer i fyra varianter. Uppdelningen baseras på hur tumören växer i huden och denna diagnos ställs patologiskt-mikroskopiskt. De olika varianterna har emellertid också olika utseende för ögat och har olika kännetecken vid undersökning med dermatoskop. En av basalcellscancerformerna sitter ytligt i huden. Vid denna form finns, förutom kirurgi, också flera andra behandlingsalternativ. I den fjärde studien har vi undersökt hur väl dermatologen, före operation kan bedöma (prediktera) vilken variant av basalcellscancer tumören tillhör. Vi studerade särskilt ytlig basalcellscancer eftersom man gärna vill kunna behandla denna tumörform med alternativa behandlingsmetoder, utan att behöva ta ett hudprov innan. Vi kunde, liksom i vårt första arbete, konstatera hög träffsäkerhet för diagnosen basalcellscancer. Däremot var det svårare att med säkerhet pricka rätt vad gäller de olika formerna. Efter ett utbildningstillfälle för alla doktorer på hudkliniken i Helsingborg om dermatoskopisk undersökning av basalcellscancer, ökade säkerheten i prediktionen av den ytliga formen för de fall som undersökts med dermatoskop.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis har vi visat på hög träffsäkerhet för diagnosen malign tumör och basalcellscancer. Antalet godartade pigmentförändringar som tas bort per melanom är högst på bålen och minskar med ökande ålder på patienten. Användning av en förenklad algoritm för dermatoskopisk undersökning av pigmentförändringar hittade stor andel av melanomen, men var sämre på att utesluta melanom hos de friska. Prediktionen av ytlig basalcellscancer förbättrades för de förändringar som undersökts med dermatoskop efter ett utbildningstillfälle om dermatoskopi av basalcellscancer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/df5f663a-15c2-4803-9b1a-0d4037f616bf</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Ingela_Ahnlide.pdf">https://portal.research.lu.se/files/3030914/8167764.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">17915041</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>skin cancer diagnosis</topic> <topic>skin cancer</topic> <topic>skin surgery</topic> <topic>dermoscopy</topic> <topic>basal cell carcinoma</topic> <topic>squamous cell carcinoma</topic> <topic>melanoma</topic> <topic>dysplastic naevus</topic> <topic>naevus</topic> <topic>algorithms</topic> </subject> <subject authority="lup"> <topic>Dermatology and Venereal Diseases</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-204-7</identifier> <identifier type="oldLupId">8167434</identifier> <part> <detail type="volume"> <number>2015:124</number> </detail> <extent unit="pages"> <total>93</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-11-27T13:00:00+01:00</dateOther> <note type="additionalInfo">Additional funds that supported this research work: Hudfonden Thorsten Birger Segerfalks stiftelse Vera och Carl J Michaelsens fond</note> <recordInfo> <recordIdentifier>df5f663a-15c2-4803-9b1a-0d4037f616bf</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:29+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:29+02:00</recordDateApproved> </recordInfo> </mods>

I propose the following definitions to illustrate the main alternatives: (1) if a practice is determined by an ethical theory and the ethical theory is not determined by practice, it is possible to speak of a top-down model of ethical thinking. (2) If a theory, conversely, is determined by a practice and the practice is not determined by theory, it can be described as a bottom-up model. (3) If a practice is used in order to determine an ethical theory, which in turn can be used to assess new practical situations in a constantly evolving process, it can be labelled an interaction model. (4) Finally, it is possible that certain practices are the basis of morality, and do not need to be systemized in any ethical theory. &lt;br/&gt;&lt;br&gt; The focus of this study is on alternatives (2), (3) and (4) where practice is given due weight and is characterized by a rejection of a strictly theoretical approach to ethics. I address representatives from some of the most influential alternatives such as: (2) Albert R Jonsen &amp;amp; Stephen Toulmin (casuistry), (3) Jürgen Habermas (discourse ethics), Alasdair MacIntyre (virtue ethics), Jonathan Haidt (experimental ethics) and (4) John Dewey, Hilary Putnam and Richard Rorty (pragmatism). I also discuss how some prominent theologians, such as Stanley Hauerwas (Christian virtue ethics) and James Gustafson (theocentric ethics), deal with similar questions. The purpose of this study is therefore to identify various positions represented in the debate, and to examine which consequences they have for how decisions are made and justified within an ethical framework.&lt;br/&gt;&lt;br&gt; I argue that the strength of models that include practical concerns in ethical thinking is that they can contribute to our understanding of why ideals, norms and values differ between various social spheres, and how they change over time. Instead of taking the traditional position, where a basic assumption about the nature of moral questions is crucial to identify a reliable approach, it is possible to assess which approaches give reliable results and use these to identify the factors relevant to answer moral questions. I identify two main alternatives: a paradigmatic and a discursive way of treating moral issues. They address various aspects of human life and action, which means that they do not exclude, but rather enrich each other in the context of an overall debate. It seems possible that both types of studies can provide reasons for performing an action or accepting a theory, which can then be revised and give rise to new positions. From such a perspective, neither the image of man and the world, nor our standards, ideals and values are necessarily static, but can be revised and reconsidered within the context of a changing social, cultural and historical context.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a16a0a12-1d70-4d5d-8c5a-15a5b9190736</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Niclas_LindstrAPm_FAPrhAY_llandet_mellan_praxis_och_teori_inom_etiken.pdf">https://portal.research.lu.se/files/3031020/3168008.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2040620</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Practice</topic> <topic>theory</topic> <topic>norms</topic> <topic>ideals</topic> <topic>principles</topic> <topic>moral philosophy</topic> <topic>casuistry</topic> <topic>discourse ethics</topic> <topic>virtue ethics</topic> <topic>theocentric ethics</topic> <topic>pragmatism</topic> <topic>experimental ethics</topic> <topic>empirically informed ethics.</topic> </subject> <subject authority="lup"> <topic>Philosophy, Ethics and Religion</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in Ethics and Theology</title> </titleInfo> <identifier type="issn">1102-769X</identifier> <identifier type="isbn">978-91-975249-7-1</identifier> <identifier type="oldLupId">3168006</identifier> <part> <detail type="volume"> <number>16</number> </detail> <extent unit="pages"> <total>290</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-12-14T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>a16a0a12-1d70-4d5d-8c5a-15a5b9190736</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:30+02:00</recordDateApproved> </recordInfo> </mods>

This has generated a rich discussion on the mechanisms behind the process and, to a lesser extent, a debate on positive and negative outcomes of gentrification. Critical voices have depicted gentrification as a global urban strategy within a neoliberal policy agenda. This thesis aims to enhance our knowledge of gentrification processes in Swedish metropolitan areas. It does so by an extensive mapping of gentrification processes in Stockholm, Gothenburg and Malmö during 1986-2001. It also contains a smaller study of island gentrification in the southern parts of the Gothenburg archipelago. The time period is divided into three five-year periods roughly corresponding to the periodicity of waves of gentrification identified in the international research literature. The results provide telling insights into gentrification as a generic process affecting not just low income areas (classical gentrification) and high income areas (super-gentrification), but also a wide-ranging spectrum of medium-income areas (ordinary gentrification). Furthermore, mapping of gentrification and opposite processes of filtering are analyzed in relation to increasing social polarization in Sweden and neoliberal political reforms. Since the beginning of the 1990s Swedish housing policies have been radically transformed. Promotion of owner-occupancy and abandonment of the long-standing policy of tenure neutrality are aspects of the new policy discourse, with far-reaching effects on gentrification.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/80392911-7168-47a8-bc09-38d74695d91f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Karin_Hedin_lic-kappa.pdf">https://portal.research.lu.se/files/3031131/1608693.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">829998</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>gentrification</topic> <topic>polarization</topic> <topic>neoliberalism</topic> <topic>housing policy</topic> <topic>Bostadspolitik</topic> <topic>filtrering</topic> <topic>gentrifiering</topic> <topic>nyliberalism</topic> <topic>polarisering</topic> </subject> <subject authority="lup"> <topic>Human Geography</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Meddelanden från Lunds universitets geografiska institutioner.

Various laser-based optical diagnostic techniques were used to collect information under different operational conditions. Combined flow- and scalar field measurements were performed at high repetition rates for detailed studies of the turbulent flames. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A large part of the work presented concerns experimental studies of lean turbulent premixed flames stabilized by a low-swirl burner. The unconfined flames that were studied were propagating in a divergent flow field and interacted with flow structures in the shear layers surrounding them. Particle Image Velocimetry (PIV) and stereo-PIV were employed for velocity measurements in a given plane. Volumetric Velocimetry (3D PIV) was performed in order to assess the full 3D characteristics of the flow field. Flame-front visualization and fuel distribution measurements were obtained by use of Planar Laser Induced Fluorescence (PLIF). PLIF of OH radicals, created in regions where high temperature reactions occurred, were used to determine the position, fluctuation, overall shape and wrinkling of the flame front. Simultaneous measurements, performed at repetition rates of several thousand images per second, of the velocity field and of flame location enabled information concerning the flow strucutres emanating from the nozzle and the flame flow interaction. The results obtained were used for validation of Large Eddy Simulations (LES), carried out by collaborating groups in parallel with the experiments. The influence of the inflow boundary conditions were investigated using both experimental data and LES of the flow through the swirler and nozzle.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; An investigation of flames close to flashback was carried out in a burner having a variable degree of swirl and equipped with an transparent nozzle. PIV and high-speed video of the flame luminosity were used to study the transition to flashback when the degree of swirl was increased. The observed flashback velocity was much higher than the estimated burning velocity of the flame and the flashback was attributed a convection directed upstream.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A demonstration of simultaneous measurements of the flow field and the temperature field was also included. Here, thermographic phosphor particles were used both as flow tracers for PIV and as temperature sensitive particles. For the temperature measurements a Nd:YAG laser at 355 nm was used to excite the particles following a heated air flow. The subsequent phosphorescence from two emission lines was collected and an intensity-ratio method was then employed for assessing the gas temperature field.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Den värld vi lever i drivs till stora delar av förbränning. Det mesta vi gör kräver energi, elektricitet för matlagning och bensin eller diesel för transporter. Sett över hela världen kommer den största delen av den energi som förbrukas från förbränning. Främst är det fossila bränslen, olja och kol, som används, men en ökande del kommer från förnyelsebara bränslen. Vid förbränning bildas olika miljöfarliga ämnen såsom kväveoxider, svaveloxider, kolmonoxid och oförbrända kolväten. Dessa ämnen kan ge upphov till försurning, smog, och skador på ozonlagret. Vissa ämnen, speciellt koldioxid, bidrar till växthuseffekten som gradvis höjer medeltemperaturen på jorden. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Kväveoxider bildas vid all förbränning i luft vid hög temperatur, oberoende av bränslets kemiska sammansättning. Utsläppen av dessa ämnen kan minskas genom att sänka temperaturen under förbränning. En etablerad metod för att åstadkomma detta är att använda en luft-bränsleblandning med ett stort överskott på luft. Önskvärt är att optimera förbränningsprocessen så att en så låg temperatur som möjligt erhålls, samtidigt som förbränningen hålls stabil. För att studera detta krävs experiment. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingen används laserdiagnostik för att studera de kemiska och fysikaliska processer som styr förbränningsprocesser. Laserbaserade mätmetoder stör inte de observerade processerna då inga fysiska mätprober används. Laserljus passerar genom förbränningszonen och mätsignalen samlas in med känsliga kameror. I den mätmetod som främst använts för att karakterisera flödesfält används korta laserpulser som ”fotoblixtar”. Laserljuset passerar optik som skapar ett tunt laserark som lyser upp den del av flödesfältet som ska studeras. Små partiklar, som blandas in i gasflödet, fungerar som flödesmarkörer. För att hastigheten ska kunna bestämmas tas två bilder med ett avpassat tidsavstånd så att partiklarna hinner flytta sig en kort sträcka. Genom att jämföra partikelmönstret i de två efterföljande bilderna kan medelförflyttningen av partiklar inom små områden beräknas. Genom detta kan hastighetsvektorer beräknas och en ögonblicksbild av hela flödesfältet byggas upp. I avhandlingen demonstreras även att man med fyra kameror som avbildar en volym med partiklar, upplysta av laserljus, gör det möjligt att ta fram det tre-dimensionella flödesfält. Detta görs i flera steg; först avbildas partiklarna i volymen från fyra håll, genom informationen i de erhållna bilderna återskapas den avbildade volymen digitalt, sedan kan flyttningen av partiklar inom små områden mellan två efterföljande rekonstruktioner beräknas och hastighetsvektorer presenteras. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att visualisera flamfronten i de flammor som studerats används också en laserbaserad teknik. Eftersom olika ämnen absorberar olika våglängder kan man välja vilket ämne man vill studera. Ämnet som absorberar laserljusets våglängd exciteras och sänder ut ljus med specifika våglängder som kallad fluorescens. Hydroxylradikaler, OH, bildas i regioner med högtemperaturreaktioner. I de undersökta flammorna kan områden med bränt och obränt separeras genom fördelningen av OH och flamfronten kan definieras av en linje mellan dessa två områden. Genom kombinerade mätningar av flödesfältet och flamfrontens position går det att undersöka hur virvlar som finns i turbulenta flöden påverkar flamfrontens rörelse och karaktär. Speciella laser- och kamera system som kan ta många tusen bilder per sekund krävs för att följa förbränningsförloppet. I Lund har vi haft möjlighet att genomföra sådana tidsupplöst mätningar och skapa filmsekvenser där inverkan av turbulenta virvlar på flamfronters dynamik tydligt kan studeras. Kunskapen om samverkan mellan flödesfält och förbränning är mycket viktigt för att utveckla och förbättra förbränningsapparater för att minska negativ miljö- och klimatpåverkan från förbränning. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Som ett steg att utveckla mätmetoder för mätning av flödesfält samtidigt med skalära storheter genomfördes försök med termografiska fosforer i gasflöden. Dessa fosforer är små temperaturkänsliga partiklar som i de aktuella försöken även fungerade som flödesmarkörer. Försöken visade på goda möjligheter för en fortsatt utvecklingen av tekniken för användning inom förbränningsstudier.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För utveckling av nya brännare används avancerade simuleringsverktyg. Med hjälp av förenklade beskrivningar av de kemiska och fysikaliska processer som sker vid förbränning kan simuleringar allt bättre beräkna förloppet av förbränningsprocesser i industriella brännare. För att detta skall fungera krävs att simuleringar först jämförs mot experimentdata för att kontrollera att modellerna ger rätt resultat. I denna doktorsavhandling har viktiga parametrar för validering av simuleringar samlats in för olika förblandade flammor med hjälp av laserdiagnostik.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a6e40c03-f8dd-4295-ab30-cf55998d6fc9</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="elektronisk_pdf_version.pdf">https://portal.research.lu.se/files/3031390/4255515.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">17313300</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Combustion Physics, Department of Physics, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Volumetric Velocimetry</topic> <topic>Low-swirl Flames</topic> <topic>Premixed Flames</topic> <topic>Turbulent Combustion</topic> <topic>Particle Image Velocimetry</topic> <topic>Laser Diagnostics</topic> <topic>A.2014:Petersson</topic> <topic>Combustion Diagnostics</topic> </subject> <subject authority="lup"> <topic>Atom and Molecular Physics and Optics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Reports on Combustion Physics</title> </titleInfo> <identifier type="issn">1102-8718</identifier> <identifier type="isbn">9789174738407</identifier> <identifier type="oldLupId">4253486</identifier> <part> <detail type="volume"> <number>172</number> </detail> <extent unit="pages"> <total>198</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-02-21T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>a6e40c03-f8dd-4295-ab30-cf55998d6fc9</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:34+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:34+02:00</recordDateApproved> </recordInfo> </mods>

To what extent is less studied. Routinely collected healthcare&lt;br/&gt;&lt;br&gt; registers is a potential resource for epidemiological studies of musculoskeletal disorders. Skåne region, as opposed to&lt;br/&gt;&lt;br&gt; nationally in Sweden, has healthcare registers, covering all care including primary care.&lt;br/&gt;&lt;br&gt; he overall aim of this thesis was to incorporate healthcare registers in the epidemiological research of consultation&lt;br/&gt;&lt;br&gt; prevalence, healthcare consultation and sick leave patterns in patients with musculoskeletal disorders.&lt;br/&gt;&lt;br&gt; he thesis comprises four studies in which the Skåne Healthcare Register was linked with national registers on sick&lt;br/&gt;&lt;br&gt; leave, prescribed drugs, and socioeconomic status. Additionally, the thesis include a comparative study between data&lt;br/&gt;&lt;br&gt; from the Skåne Healthcare Register with that of an United Kingdom (UK) consultation database. he main variables&lt;br/&gt;&lt;br&gt; under study are in Paper I–III disease, consultations, and sick leave and in Paper IV education, income, and work status.&lt;br/&gt;&lt;br&gt; he consultation prevalence of low back pain was estimated to 3–4% in the Skåne region while the figure was larger&lt;br/&gt;&lt;br&gt; in the UK. People having low back pain had increased levels of healthcare consultations in general, and more pain diagnoses&lt;br/&gt;&lt;br&gt; in particular. People diagnosed with whiplash associated neck injury had higher healthcare consultation rates&lt;br/&gt;&lt;br&gt; already three years before the neck injury and the postinjury consultation level was associated with the preinjury consultation&lt;br/&gt;&lt;br&gt; levels. Low socioeconomic status was associated with being diagnosed with chronic pain.&lt;br/&gt;&lt;br&gt; It was feasible to use routinely collected databases in the studies of the burden of disease from musculoskeletal disorders,&lt;br/&gt;&lt;br&gt; thus potentially also for other public health disorders. While there are vast potentials with register data, it is also&lt;br/&gt;&lt;br&gt; important to bear in mind limitations due to e.g., missing data and misclassification which may introduce bias. My&lt;br/&gt;&lt;br&gt; main findings indicate a need for early interventions after initial pain and neck injury to prevent the pain to becoming&lt;br/&gt;&lt;br&gt; chronic. Stratification-based management is especially suggested.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3ec8c851-4d45-420e-ad53-4d9bcd5f7b62</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Anna_jAPud_kappa.pdf">https://portal.research.lu.se/files/3031615/4145822.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">449475</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Orthopaedics, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Musculoskeletal</topic> <topic>pain</topic> <topic>neck injury</topic> <topic>consultation</topic> <topic>sick leave</topic> <topic>pharmaceuticals</topic> <topic>epidemiology</topic> <topic>register</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-95-6</identifier> <identifier type="oldLupId">4145806</identifier> <part> <detail type="volume"> <number>2013:122</number> </detail> <extent unit="pages"> <total>88</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-11-29T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>3ec8c851-4d45-420e-ad53-4d9bcd5f7b62</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:36+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:36+02:00</recordDateApproved> </recordInfo> </mods>

The motivation for research on the first subject is the need for flexible and accurate production processes employing industrial robots as their main component. The challenge to overcome here is to achieve high-accuracy machining solutions, in spite of strong process forces affecting the robot end-effector. Because of the process forces, the nonlinear dynamics of the manipulator, such as the joint compliance and backlash, significantly degrade the achieved position accuracy of the machined part. In this thesis, a macro/micro manipulator configuration is considered to the purpose of increasing the position accuracy. In particular, a model-based control architecture is developed for control of the micro manipulator. The macro/micro manipulator configuration are validated by experimental results from milling tests in aluminium. The main result is that the proposed actuator configuration, combined with&lt;br/&gt;&lt;br&gt; the control architecture proposed in this thesis, can be used for increasing the accuracy of industrial machining processes with robots.&lt;br/&gt;&lt;br&gt; The interest for research on optimal control of road-vehicles in timecritical maneuvers is mainly driven by the desire to devise improved vehicle safety systems. Primarily, the solution of an optimal control problem for a specific cost function and model configuration can provide indication of performance limits as well as inspiration for control strategies in time-critical maneuvering situations. In this thesis, a methodology for solving this kind&lt;br/&gt;&lt;br&gt; of problems is discussed. More specifically, vehicle and tire modeling and the optimization formulation required to get useful solutions to these problems are investigated. Simulation results are presented for different vehicle models, under varying road-surface conditions, in aggressive maneuvers, where in particular the tires are performing at their limits. The obtained results are evaluated and compared. The main conclusion here is that even simplified road-vehicle models are able to replicate behavior observed when experienced drivers are handling vehicles in time-critical maneuvers. Hence, it is plausible that the results presented in this thesis provide a basis for development of future optimization-based driver assistance technologies.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4d71a2bf-1a12-4d5f-97df-09e57d18de7c</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="lic_bo.pdf">https://portal.research.lu.se/files/3031890/3633406.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8365339</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Research Reports TFRT-3259</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">3633403</identifier> <part> <extent unit="pages"> <total>131</total> </extent> </part> </relatedItem> <note type="additionalInfo">&quot;month=April&quot;</note> <recordInfo> <recordIdentifier>4d71a2bf-1a12-4d5f-97df-09e57d18de7c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:38+02:00</recordDateApproved> </recordInfo> </mods>

To experimentally study autoimmunity, we have used murine models that mimic their human counterparts; experimental autoimmune encephalomyelitis (EAE) – a model for MS, and collagen induced arthritis (CIA) and antigen induced arthritis (AIA) – models for RA. &lt;br/&gt;&lt;br&gt; A sub-population of T cells, termed natural killer T cells (NKT), have been suggested as having immunoregulatory features in pathogenic autoimmunity. How NKT cells are activated to perform this regulation and by which functional pathways they act is not completely understood. A number of natural antigens activating NKT cells via the antigen presenting molecule CD1d have so far been identified as glycolipids originating from either bacteria or self.&lt;br/&gt;&lt;br&gt; This thesis investigates the role of NKT cells in autoimmune tissue-specific inflammation. We found that NKT cells can down-regulate both the central nervous system-specific autoimmunity in EAE, and the joint-specific inflammation in experimentally induced arthritis. We also show data indicating that this regulation requires activation in the periphery, and we have identified a natural self-peptide capable of exerting this activation; A CD1d restricted peptide derived from autologous collagen type II. By vaccinating mice with this peptide we were able to ameliorate the inflammation and reduce the disease phenotype in both CIA and EAE. We also found the peptide-specific NKT cells capable of suppressing activated T cells in vitro. Taken together, this thesis show that CD1d restricted NKT cells can be activated to down-regulate pathogenic autoimmunity, and should be investigated as targets for future autoimmune therapies.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8cc38351-7a8d-4947-b952-6adfd89dab75</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="RamberA__ttelse_FINAL_2014.pdf">https://portal.research.lu.se/files/3032603/4300856.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">547943</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Autoimmunity</topic> <topic>NKT cells</topic> <topic>CD1d antigen presentation</topic> <topic>Multiple sclerosis</topic> <topic>Rheumatoid arthritis</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-42-7</identifier> <identifier type="oldLupId">4294855</identifier> <part> <detail type="volume"> <number>2014:18</number> </detail> <extent unit="pages"> <total>59</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-03-04T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>8cc38351-7a8d-4947-b952-6adfd89dab75</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:50+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:50+02:00</recordDateApproved> </recordInfo> </mods>

Insidious onset back pain, morning stiffness, waking up at night, and improvement from exercise are common characteristics. The disease is life-long, often with early onset, and can cause limitations in physical function, affecting the ability to work, and has a negative effect on health-related quality of life. The overall aim of the present work was to describe the prevalence of SpA and to study the consequences for the individual and society regarding physical activity and work in a population-based cohort of patients seeking health care.&lt;br/&gt;&lt;br&gt; The studies are based on a cohort of patients with SpA, identified through the Skåne Health Care Register by searching for 12 ICD-10 codes for SpA that had led to a doctor’s consultation 2003–2007. Two questionnaire surveys in 2009 and 2011 were sent to all the patients in the cohort &amp;gt;18 years and data from these formed the basis of the studies II, III, and IV.&lt;br/&gt;&lt;br&gt; Study I: The estimation of SpA prevalence based on almost 4,000 patients was 0.45% in adults (≥ 15 years), and equally common in women and men. The prevalence in different subgroups was 0.12% in AS, 0.25% in PsA, 0.0015% in Aa-IBD, and 0.10% in USpA. &lt;br/&gt;&lt;br&gt; Study II dealt with the proportion of patients who met the WHO recommendations for physical activity. Seven out of ten patients with SpA met the recommendations, more frequently in women than in men, and with a somewhat higher proportion in the SpAScania cohort than in the general Swedish population. &lt;br/&gt;&lt;br&gt; Studies III and IV examined the patterns of reduced productivity at work both cross-sectionally and longitudinally. Just under half of the patients with SpA reported reduced productivity at work, and more reduction was reported in women than in men. Reduced productivity at work was associated with, and could be predicted from several patient-reported outcome measures (PROMs) such as reduced health-related quality of life (HRQoL), higher disease activity, lower physical function, lower self-efficacy, worse mental health and low education level. &lt;br/&gt;&lt;br&gt; To conclude, 45 individuals out of 10,000 have a diagnosis of SpA, and affected individuals report significant consequences of the disease. The findings presented in this thesis could help clinicians to identify patients at an early stage at risk of a worse prognosis using simple clinical questions in routine practice, and tailor the activities, treatment, and care for patients with SpA.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/26ee7fa6-a20d-497e-9d2b-908a0085f771</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Emma_Haglund.pdf">https://portal.research.lu.se/files/3032628/4091720.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1319243</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Rheumatology, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Spondyloarthritis</topic> <topic>ankylosing spondylitis</topic> <topic>psoriatic arthritis</topic> <topic>undifferentiated spondyloarthritis</topic> <topic>prevalence</topic> <topic>physical activity</topic> <topic>work productivity</topic> <topic>presenteeism</topic> <topic>absenteeism</topic> <topic>patient-reported outcomes</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-79-6</identifier> <identifier type="oldLupId">4091718</identifier> <part> <detail type="volume"> <number>2013:107</number> </detail> <extent unit="pages"> <total>89</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-11-08T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>26ee7fa6-a20d-497e-9d2b-908a0085f771</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:52+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:52+02:00</recordDateApproved> </recordInfo> </mods>

The three regions represent about 11.8% of the world land area and the countries&lt;br/&gt;hosted approximately 9% of the world population in 1950 and 2008 and are also projected to do so in 2050. The results obtained for desalination capacity in the study area were 62%, 58% and 60% of the world capacity for 1996, 2008, and 2050, respectively. The increase in the recovery ratio is considered an important factor in this study. In 1996 this ratio was about 30 to 35%, and in 2008 it was 40 to 45%, although in some plants it reached up to 50%. The gulf desalination capacities were obtained as 50, 40 and 45% of total world capacity at the end of 1996, 2008 and 2050 (prognosis) respectively.&lt;br/&gt;All Middle Eastern countries suffer from a shortage of water along with increasing demand due to high population growth. Desalination can be a cost-effective way to produce fresh water and possibly electricity. A suggested solution for Sinai and the Gaza Strip involves the building of a joint power and desalination plant, located in Egypt close to the border with Gaza. This joint Egypt-Palestine project would increase the water supply by 500,000 m3/d and the power supply by 500MW. The result emerged from field work and the two experiments can also be applied to the design of this project. Water and salt mass balances for the Dead Sea were modelled by including and excluding the water from the proposed Red Sea Dead Sea Canal project, RSDSC. Precipitation, evaporation, river discharges, ground water flows, input/output from potash companies and salt production in addition to brine discharge were included in the models. The mixing time in the Dead Sea was modelled using a single-layer (well-mixed) and a two-layer (stratified) system.&lt;br/&gt;An efficient method for increasing the dilution rate of brine water discharged into the sea is an inclined negatively buoyant jet of a single port or multi-diffuser. Two small-scale experimental studies were conducted to investigate the behaviour of a dense jet discharged into lighter ambient water. The first lab-scale experiment concerned the benefit of the initial angle of inclined dense jets, where the slope increased for the maximum levels as a function of this angle. An angle of 60 deg. led to a better result than 30 or 45 deg. An empirical prediction was found based on five geometric quantities to be considered in the future plan.&lt;br/&gt;Field work measurements have been conducted in Cyprus, where the brine from a desalination plant and the Mediterranean Sea coastline have been investigated at the Eastern Mediterranean University. The result from the measured data demonstrates the need for more than one outfall (a series of outfalls) to the sea to avoid or minimize environmental impact on the coastline. The result also agreed well with simple, two dimensional mathematical models assuming Gaussian distribution. The calculated bottom slope is about 7.4%, which can explain the pollution that appears at the coast close to the discharge point. Thus small slope could be one reason.&lt;br/&gt;The second lab-scale experiment studied the near and intermediate fields of negatively buoyant jets. The dilution along the flow was increased by about 10% and 40% with bottom slope and bottom slope together with a 30 degree jet&lt;br/&gt;inclination, respectively. This method can be applied in brine discharge outlets to recipients to minimize concentration and facilitate faster and greater dilution. Over 16% bottom slope and more field work is needed for comparison with this result. It was found that an inclination of 30 degrees with 16 % bottom slope was more sustainable in designing brine discharge outfall. A Matlab code can be used to describe the lateral spreading and centerline dilution of buoyant jets and plumes in near and intermediate fields.&lt;br/&gt;</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Avsaltning av havsvatten utgör en viktig källa för vattenförsörjning till befolkningen som bor&lt;br/&gt;&lt;br&gt; vid Persiska viken, Medelhavet och Röda havet. De tre regionerna utgör ca 11,8 % av världens&lt;br/&gt;&lt;br&gt; landyta och hade omkring 9 % av världens befolkning under 1950 och 2008, samt lika mycket&lt;br/&gt;&lt;br&gt; enligt prognos för år 2050. Dessa områden är hemvist för 62 %, 58% och 60% av världens&lt;br/&gt;&lt;br&gt; avsaltningskapacitet för år 1996, 2008 respektive 2050. Utbytet av dricksvatten ur havsvatten&lt;br/&gt;&lt;br&gt; har identifierats som en viktig faktor i denna studie. Under 1996 uppgick utbytet till cirka 30-35&lt;br/&gt;&lt;br&gt; % och år 2008 var det cirka 40-45 %, medan vissa avsaltningsanläggningar nådde upp till hela&lt;br/&gt;&lt;br&gt; 50 %. Runt Persiska viken fanns och finns 50 %, 40 % och 45 % av världens totala&lt;br/&gt;&lt;br&gt; avsaltningskapacitet i slutet av 1996, 2008 respektive 2050 (prognos).&lt;br/&gt;&lt;br&gt; Alla länder i Mellanöstern lider av brist på vattenresurser samtidigt med en ökad efterfrågan av&lt;br/&gt;&lt;br&gt; vatten på grund av den höga befolkningstillväxten. Avsaltning kan vara ett kostnadseffektivt&lt;br/&gt;&lt;br&gt; sätt att producera färskvatten och möjligtvis också el. En lösning för Sinai och Gazaremsan&lt;br/&gt;&lt;br&gt; föreslås som innebär att en gemensam kraft- och avsaltningsanläggning uppförs i Egypten nära&lt;br/&gt;&lt;br&gt; gränsen till Gazaremsan. Detta gemensamma Egypten-Palestina projekt skulle öka&lt;br/&gt;&lt;br&gt; vattenförsörjningen med 500 000 m3/d och kraftförsörjningen med 500 MW i regionen.&lt;br/&gt;&lt;br&gt; Resultatet från fältarbete och två experiment i laboratorieskala redovisas. De kan även tillämpas&lt;br/&gt;&lt;br&gt; för att utforma detta projekt. Massbalanser för vatten och salt för Döda havet modellerades&lt;br/&gt;&lt;br&gt; genom att inkludera och exkludera vatten från ett föreslaget projekt att överföra vatten från&lt;br/&gt;&lt;br&gt; Röda havet till Döda havet i en kanal (RSDSC). Nederbörd, avdunstning, ytvattenflöde,&lt;br/&gt;&lt;br&gt; grundvattenflöden, samt uppgifter för tillflöde och avlopp från mineralutvinningsföretag runt&lt;br/&gt;&lt;br&gt; Döda havet användes i modellen. Blandningstiden i Döda havet modellerades genom att&lt;br/&gt;&lt;br&gt; använda två olika ekvationssystem, för väl omblandade respektive skiktade förhållanden.&lt;br/&gt;&lt;br&gt; En effektiv metod för att påskynda utspädningen av det salta rejektvattnet från&lt;br/&gt;&lt;br&gt; avsaltningengsverket i recipienten är att använda en vinklad utgångsstråle eller spridning med&lt;br/&gt;&lt;br&gt; multipla utlopp. Två experimentella studier i laboratorieskala utfördes för att undersöka hur en&lt;br/&gt;&lt;br&gt; tung/tät stråle fördelades i omgivande vatten. Den första studien gjordes med vinklade&lt;br/&gt;&lt;br&gt; tunga/täta strålar för att studera betydelsen av utloppsstrålens vinkel, där lutningen ökade för de&lt;br/&gt;&lt;br&gt; maximala nivåerna som funktion av denna vinkel. En utloppsvinkel på 60 grader ger snabbare&lt;br/&gt;&lt;br&gt; inblandning än 30 eller 45 grader. En empirisk relation för effektiv inblandning togs fram som&lt;br/&gt;&lt;br&gt; funktion av fem geometriska parametrar, vilken kan användas för framtida planering.&lt;br/&gt;&lt;br&gt; Fältundersökningar har gjorts på Cypern av hur rejektplymer från Eastem Mediterranean&lt;br/&gt;&lt;br&gt; Universitys avsaltningsanläggning fördelas lokalt i Medelhavet. Mätningarna visar att det&lt;br/&gt;&lt;br&gt; behövs mer än ett utlopp (multipla utlopp) ut till havet för att undvika eller minimera&lt;br/&gt;&lt;br&gt; miljöpåverkan längs kusten. Resultatet överensstämde väl med en enkel två-dimensionell&lt;br/&gt;&lt;br&gt; matematiska modell för spridning om plymen antas vara normalfördelad. Den beräknade&lt;br/&gt;&lt;br&gt; bottenlutningen i fält var låg, omkring 7,4 %, vilket delvis kan förklara varför smuts från&lt;br/&gt;&lt;br&gt; avsaltningen syntes på stranden i närheten av utsläppspunkten.&lt;br/&gt;&lt;br&gt; Ett andra laboratorieexperiment gjordes för att undersöka hur flödesfältet från tunga&lt;br/&gt;&lt;br&gt; saltvattenplymer såg ut nära utloppet och i mellanzonen innan plymen fördelats ut i recipienten.&lt;br/&gt;&lt;br&gt; Utspädningen längs plymen ökade med cirka 10 % och 40 % om botten lutade respektive om&lt;br/&gt;&lt;br&gt; botten lutade och strålen riktades 30 grader upp från horisontalplanet. Resultat av denna studie&lt;br/&gt;&lt;br&gt; kan användas för konstruktion av utlopp från avsaltningsverk för att minimera&lt;br/&gt;&lt;br&gt; saltkoncentrationsskillnader och för att få plymen att spädas ut snabbare och mera i recipient.&lt;br/&gt;&lt;br&gt; Mer än 16 % bottenlutning rekommenderas, liksom flera fältmätningar. En utloppsvinkel på 30&lt;br/&gt;&lt;br&gt; grader med 16 % bottenlutning ger mindre miljöpåverkan. De geometriska effekterna kan&lt;br/&gt;&lt;br&gt; modelleras framgångsrikt i Matlab.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/73bf9966-0f53-4ae5-948c-f12678777d13</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="My_PhD_theses_final_15feb2011.pdf">https://portal.research.lu.se/files/3032844/1788451.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">22444468</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <edition>1052</edition> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Modelling.</topic> <topic>Field data analysis</topic> <topic>Negatively buoyant jet</topic> <topic>Experiment</topic> <topic>Brine discharge</topic> <topic>Desalination</topic> <topic>Water supply</topic> </subject> <subject authority="lup"> <topic>Water Engineering</topic> <topic>Other Social Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>LUTVDG/(TVVR-1052)(2011)</title> </titleInfo> <identifier type="issn">1101-9824</identifier> <identifier type="isbn">978-91-7473-058-6</identifier> <identifier type="oldLupId">1788450</identifier> <part> <detail type="volume"> <number>1052</number> </detail> <extent unit="pages"> <total>211</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-03-21T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>73bf9966-0f53-4ae5-948c-f12678777d13</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:53:57+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:53:57+02:00</recordDateApproved> </recordInfo> </mods>

It is an immunophenotypically, morphologically, clinically, and genetically heterogeneous disorder that comprises several distinct subtypes. Proper classification is important because determining the correct subtype plays a vital role for prognostication and treatment strategy. During the last decades, the use of polychemotherapy and implementation of risk stratification based on the presence of certain acquired genetic changes in pediatric B-cell precursor (BCP) ALL have increased the overall survival rates substantially; they are now approaching 90%. This notwithstanding, 20% of patients still relapse and only half of these survive. A considerable proportion of all relapses lacks the high risk-stratifying genetic changes included in most current ALL treatment protocols. Hence, it is important to identify novel genetic features associated with treatment failure to ensure proper therapy intensity and to detect genes and pathways that in the future can be targeted by specific drugs.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To identify relapse-associated genetic aberrations in pediatric BCP ALL, single nucleotide polymorphism array analyses were performed on uniformly treated patients accrued between 1992 and 2011 from the Lund and Linköping University Hospitals (Article I). In the 191 successfully analyzed cases, deletions of IKZF1 (∆IKZF1) and SPRED1 were shown to be associated with a poor prognosis, with ∆IKZF1 being an independent risk factor for relapse. To ascertain whether ∆IKZF1 is an independent risk factor also in the context of minimal residual disease (MRD) findings, an extended cohort including all 334 Swedish pediatric BCP ALL cases with known IKZF1 status was investigated (Article II). That study confirmed that ∆IKZF1 confers a poor prognosis, revealed that such deletions are particularly common in cases with uninformative cytogenetics, and showed that the prognostic impact of ∆IKZF1 is independent of MRD stratification. However, coexisting genetic changes may play a role in modifying the pathogenetic and/or clinical impact of ∆IKZF1. Therefore, ∆IKZF1-positive cases were investigated further in Article III in order to identify additional, recurrent changes. Furthermore, targeted deep sequencing of all IKZF1 exons in 140 BCP ALL cases was performed, identifying sequence mutations (mutIKZF1) in 5.7%. Of the mutIKZF1-positive cases, one-fourth also harbored ∆IKZF1. In total, 35 cases with IKZF1 abnormalities (abnIKZF1), comprising ∆IKZF1 and/or mutIKZF1, could be analyzed with regard to other genetic anomalies. These analyses showed that CRLF2 rearrangements, caused by deletions of the pseudoautosomal region 1 (PAR1), and JAK2 mutations were significantly overrepresented in abnIKZF1-positive cases and that the presence of PAR1 deletions conferred a poor prognostic impact. Thus, in order to ascertain correctly the clinical ramifications of abnIKZF1 in pediatric BCP ALL, PAR1 deletions should possibly also be screened for.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Den vanligaste barncancerformen är akut leukemi, en form av blodcancer som uppstår i immunförsvarets celler och som drabbar cirka 75 barn i Sverige varje år. Även om de flesta av barnen idag botas får en av fem återfall och då minskar överlevnaden drastiskt trots intensiv behandling. Vad det är som gör leukemin mer motståndskraftig när den återkommer vet man ännu inte i detalj. Det är sålunda viktigt att man redan vid diagnostillfället så säkert som möjligt kan förutspå vilka barn som har stor risk för återfall och som av den anledningen ska få mer behandling. Det är även betydelsefullt att identifiera de leukemipatienter som kan botas med mindre aggressiv terapi, för att i görligaste mån minska biverkningar associerade med cytostatika.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Numera används genetiska analyser för att påvisa förändringar som innebär att patienten ska ha mer eller mindre intensiv behandling, något som medför en mer anpassad behandling. Detta har till stora delar bidragit till den förbättrade överlevnaden av barnleukemi de senaste åren. Det ska dock starkt betonas att många av dem som får återfall inte uppvisar några kända genetiska högrisk-markörer vid diagnostillfället. Av den anledningen är det väsentligt att hitta nya mutationer som framöver kan komma att vara riskgrupperande.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Syftet med mitt avhandlingsarbete har varit att angripa ovanstående frågeställningar genom att kartlägga genetiska förändringar som förekommer i patienter som fått återfall (recidiverat) eller inte svarat på den initiala behandlingen och att studera förekomsten av dessa mutationer i leukemiprov från barn som blivit botade, med målet att finna förändringar som är klart överrepresenterade i de fall som sedermera recidiverar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/670e0e9b-bb83-4e65-8936-649e33e535d4</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Linda_Olsson.pdf">https://portal.research.lu.se/files/3033275/4699513.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3142715</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Clinical Genetics, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Pediatric acute lymphoblastic leukemia</topic> <topic>relapse</topic> <topic>risk-stratifying factors</topic> <topic>IKZF1</topic> <topic>cooperative changes</topic> </subject> <subject authority="lup"> <topic>Medical Genetics and Genomics (including Gene Therapy)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-050-0</identifier> <identifier type="oldLupId">4699510</identifier> <part> <detail type="volume"> <number>2014:121</number> </detail> <extent unit="pages"> <total>96</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-22T10:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>670e0e9b-bb83-4e65-8936-649e33e535d4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:54:05+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:54:05+02:00</recordDateApproved> </recordInfo> </mods>

The target application in this work&lt;br/&gt;&lt;br&gt; is digital holographic imaging, where visible images are to be reconstructed&lt;br/&gt;&lt;br&gt; based on holographic recordings. The reconstruction process is computationally&lt;br/&gt;&lt;br&gt; demanding and requires hardware acceleration to achieve real-time performance.&lt;br/&gt;&lt;br&gt; Thus, this work presents two design approaches, with different levels&lt;br/&gt;&lt;br&gt; of reconfigurability, to accelerate the image reconstruction process and related&lt;br/&gt;&lt;br&gt; computationally demanding applications.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The first approach is based on application-specific hardware accelerators, which&lt;br/&gt;&lt;br&gt; are usually required in systems with high constraints on processing performance,&lt;br/&gt;&lt;br&gt; physical size, or power consumption, and are tailored for a certain&lt;br/&gt;&lt;br&gt; application to achieve high performance. Hence, an acceleration platform&lt;br/&gt;&lt;br&gt; is proposed and designed to enable real-time image reconstruction in digital&lt;br/&gt;&lt;br&gt; holographic imaging, constituting a set of hardware accelerators that are connected&lt;br/&gt;&lt;br&gt; in a flexible and reconfigurable pipeline. Hardware accelerators are&lt;br/&gt;&lt;br&gt; optimized for high computational performance and low memory requirements.&lt;br/&gt;&lt;br&gt; The application-specific design has been integrated into an embedded system&lt;br/&gt;&lt;br&gt; consisting of a microprocessor, a high-performance memory controller, a digital&lt;br/&gt;&lt;br&gt; image sensor, and a video output device. The system has been prototyped&lt;br/&gt;&lt;br&gt; using an FPGA platform and synthesized for a 0.13 μm standard cell library,&lt;br/&gt;&lt;br&gt; achieving a reconstruction rate of 30 frames per second running at 400 MHz.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The second approach is based on a dynamically reconfigurable architecture&lt;br/&gt;&lt;br&gt; to accelerate arbitrary applications, which presents a trade-off between versatileness&lt;br/&gt;&lt;br&gt; and hardware cost. The proposed reconfigurable architecture is constructed&lt;br/&gt;&lt;br&gt; from processing and memory cells, which communicate using a combination&lt;br/&gt;&lt;br&gt; of local interconnects and a global network. High-performance local&lt;br/&gt;&lt;br&gt; interconnects generate a high communication bandwidth between neighboring&lt;br/&gt;&lt;br&gt; cells, while the global network provides flexibility and access to external memory.&lt;br/&gt;&lt;br&gt; The processing and memory cells are run-time reconfigurable to enable&lt;br/&gt;&lt;br&gt; flexible application mapping. Proposed reconfigurable architectures are modeled&lt;br/&gt;&lt;br&gt; and evaluated using Scenic, which is a system-level exploration environment&lt;br/&gt;&lt;br&gt; developed in this work. A design with 16 cells is implemented and synthesized&lt;br/&gt;&lt;br&gt; for a 0.13 μm standard cell library, resulting in low area overhead when&lt;br/&gt;&lt;br&gt; compared with application-specific solutions. It is shown that the proposed&lt;br/&gt;&lt;br&gt; reconfigurable architecture achieves high computation performance compared&lt;br/&gt;&lt;br&gt; to traditional DSP processors.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1496cf27-b2dd-47d7-8077-1a23d14ae471</url> </location> </relatedItem> <originInfo> <publisher>The Department of Electrical and Information Technology</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Stream Processing</topic> <topic>Digital Holography</topic> <topic>Reconfigurable Computing</topic> <topic>Reconfigurable Architectures</topic> <topic>Run-time Reconfiguration</topic> <topic>Design Exploration</topic> <topic>Hybrid floating-point</topic> <topic>Data Scaling</topic> <topic>FFT</topic> <topic>ASIC</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Series of licentiate and doctoral thesis</title> </titleInfo> <identifier type="issn">1654-790X</identifier> <identifier type="oldLupId">1148966</identifier> <part> <detail type="volume"> <number>5</number> </detail> <extent unit="pages"> <total>175</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-06-03T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>1496cf27-b2dd-47d7-8077-1a23d14ae471</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:54:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-28T13:50:25Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:54:11+02:00</recordDateApproved> </recordInfo> </mods>

Psychoneuroimmunological mechanisms have been suggested to be involved in the pathogenesis of psoriasis and have often been shown to be related to psychological distress and pruritus in psoriasis. &lt;br/&gt;&lt;br&gt; The general aim of this thesis was to investigate psychoneuroimmunological and psychological aspects of patients with plaque psoriasis and to identify potentially psychologically vulnerable individuals by means of clinical characteristics. &lt;br/&gt;&lt;br&gt; In Paper I, a significantly increased immunohistological expression of the neuropeptide substance P (SP) and its receptor neurokinin-1 (NK-1R) was found in involved psoriatic skin compared with non-involved (n = 13). The expression of SP and NK1-R was, however, not associated with levels of pruritus. The degree of chronic stress indicated by salivary cortisol was significantly associated with increased expression of SP and NK1-R in non-involved psoriatic skin.&lt;br/&gt;&lt;br&gt; Papers II-IV are based on individual psychosocial interviews and three psychometric validated questionnaires (Swedish Universities Scales of Personality, Spielberger State-Trait Anxiety Inventory and Beck Depression Inventory-II) from 101 consecutively recruited patients with psoriasis. Three subgroups of patients with an increased psychological vulnerability could be identified: &lt;br/&gt;&lt;br&gt; Early age at onset of psoriasis, but not disease duration, was significantly associated with pessimistic personality traits and higher scores of anxiety and depression, compared with late onset psoriasis (Paper II). Patients with higher levels of pruritus showed primarily higher scores of depression and also higher scores of anxiety and negative pessimistic personality traits compared with patients with mild pruritus (Paper III). Sixty-four patients (63 %) reported a subjective association between disease exacerbation and stress, and were defined as “stress reactors” (SRs). SRs showed a significantly more vulnerable and stress susceptible personality profile and higher scores of both depression and anxiety, compared with non-stress reactors (Paper IV).&lt;br/&gt;&lt;br&gt; In conclusion, our results indicate that neuroimmunological pathways involving SP may play a key role in psoriasis. From a clinical perspective, our results suggest that when meeting patients with psoriasis, health care professionals should be more attentive to potential psychological vulnerability in patients with young age at onset, and/or severe pruritus, and/or patients who experience disease exacerbation during stress.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Psoriasis är en av våra vanligaste folksjukdomar, som drabbar 2-3 % av den vuxna befolkningen. Man vet i dag att många patienter med psoriasis lider av psykisk ohälsa och sänkt livskvalitet. Sjukdomen i sig innebär ofta en stor psykologisk påfrestning för patienten, men stress och psykisk ohälsa också kan vara en viktig orsak till insjuknande och återfall av psoriasis. Klåda är ett vanligt symtom vid psoriasis, som också visat sig ha en koppling till stress och psykisk ohälsa.&lt;br/&gt;&lt;br&gt; Huden är intimt sammankopplad ned nervsystemet och immunsystemet, vilket kan ligga till grund för sjukdomsutveckling och klåda vid psoriasis. Signalvägar via neuropeptiden substans P (SP) och dess receptor NK-1 (NK-1R) anses kunna spela en roll. I avhandlingens delarbete I fann vi signifikant ökad förekomst av SP och NK-1R i hudprover från psoriasisplack jämfört med frisk hud, men grad av klåda kunde inte associeras till ökad förekomst av varken SP eller NK-1R. Grad av kronisk stress, i form av salivkortisol var associerat till ökat förekomst av SP och NK1-R i frisk hud hos patienter med psoriasis. Således talar studieresultaten för att neuroimmunologiska signalvägar via SP kan ha betydelse vid psoriasis.&lt;br/&gt;&lt;br&gt; I avhandlingens delarbete II-IV gjordes omfattande psykologiska undersökningar av 101 patienter med psoriasis. Syftet var att försöka identifiera tydliga kliniska patientgrupper med potentiellt högre grad av psykisk ohälsa. Studierna baseras på enskilda intervjuer och psykologiska självskattningsformulär för kartläggning av psykosociala faktorer, personlighetsprofil samt grad av ångest och depression. &lt;br/&gt;&lt;br&gt; Någon speciell typ av personlighetsprofil för patienter med psoriasis som grupp kunde inte definieras. Patienterna hade inte heller mer ångest eller depressiva symptom än normalbefolkningen. Däremot fann vi att patienter med yngre ålder vid sjukdomsdebut (delarbete II) och patienter med svår klåda (delarbete III) visade sig ha signifikant högre medelvärden av ångest och depression, samt mer pessimistiska personlighetsdrag jämfört med patienter med senare debutålder eller lindrig klåda. Samtidigt fann vi att patienter som upplevde att deras psoriasis försämras av stress hade en mer sårbar och stresskänslig personlighetsprofil, samt mer ångest och depression, än de som inte upplevde att sjukdomen inte försämras av stress (delarbete IV). Således indikerar studieresultaten att de som träffar patienter med psoriasis bör vara extra lyhörda för eventuell psykisk ohälsa hos patienter med yngre debutålder, svår klåda eller patienter som upplever sjukdomsförsämring vid stress.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b287f20b-3ad9-478c-a3b0-478874566f35</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="RemrAPd_espik_G5.pdf">https://portal.research.lu.se/files/3040411/4695400.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1705686</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Psoriasis</topic> <topic>psychology</topic> <topic>Substance P</topic> <topic>Neurokinin-1</topic> <topic>stress</topic> <topic>pruritus</topic> <topic>anxiety</topic> <topic>depression</topic> <topic>personality</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-045-6</identifier> <identifier type="oldLupId">4695395</identifier> <part> <detail type="volume"> <number>2014:116</number> </detail> <extent unit="pages"> <total>86</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-07T13:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Bacteria display enzymes that modulate the glycans of&lt;br/&gt;&lt;br&gt; the immune system to weaken the host defense and favor bacterial survival. In this thesis&lt;br/&gt;&lt;br&gt; we aimed at exploring bacterial modulation of host glycosylation in infection and to&lt;br/&gt;&lt;br&gt; evaluate the usefulness of bacterial enzymes in biotechnology and for therapeutic use.&lt;br/&gt;&lt;br&gt; The role of IgG endoglycosidase EndoS in streptococcal virulence was evaluated in a&lt;br/&gt;&lt;br&gt; murine model of invasive infection and we found significant contribution when&lt;br/&gt;&lt;br&gt; heterologously expressed. We also discovered and characterized EndoS2, a novel&lt;br/&gt;&lt;br&gt; enzyme specific and conserved in serotype M49 of streptococci, with enzymatic activity&lt;br/&gt;&lt;br&gt; on the glycans of IgG and α1-acid glycoprotein. Enterococcal pathogenesis was studied,&lt;br/&gt;&lt;br&gt; and we found that the endoglycosidase EndoE cleaved glycans of lactoferrin to reduce&lt;br/&gt;&lt;br&gt; the antibacterial functions and to support bacterial growth. A glycoform specificity&lt;br/&gt;&lt;br&gt; difference between EndoS and EndoS2 was observed, and we suggested a method for&lt;br/&gt;&lt;br&gt; quantification of high-mannose glycans on therapeutic antibodies, a key quality attribute.&lt;br/&gt;&lt;br&gt; Finally, we explored the importance of Fc glycosylation of IgE and showed that EndoS&lt;br/&gt;&lt;br&gt; cleaved glycans of this immunoglobulin causing a reduction of the immune cell activation&lt;br/&gt;&lt;br&gt; in vivo, a potential new therapeutic strategy for severe IgE mediated allergies.&lt;br/&gt;&lt;br&gt; In this thesis we demonstrate that glycans are an integral part of the immune system, and&lt;br/&gt;&lt;br&gt; that the study of bacterial effectors of glycosylation paves the way for a deeper&lt;br/&gt;&lt;br&gt; understanding of infections, for novel tools supporting the biotech arena, and for new&lt;br/&gt;&lt;br&gt; therapeutic strategies.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Hur gör bakterier för att komma undan immunförsvaret? Vi har studerat hur en&lt;br/&gt;&lt;br&gt; vanligt förekommande bakterie, grupp A streptokocker, gör för att undvika kroppens&lt;br/&gt;&lt;br&gt; immunförsvar vid infektion. Vi har upptäckt enzymer som bidrar till bakteriens&lt;br/&gt;&lt;br&gt; förmåga att undvika immunförsvaret genom att avväpna antikroppar. De bakteriella&lt;br/&gt;&lt;br&gt; enzymerna kan användas i bioteknisk industri och eventuellt som framtida läkemedel.&lt;br/&gt;&lt;br&gt; Alla kroppens celler innehåller proteiner och många proteiner i kroppen är&lt;br/&gt;&lt;br&gt; glykosylerade och kallas glykoproteiner. Det betyder att proteinerna bär kedjor av&lt;br/&gt;&lt;br&gt; socker som är viktiga för proteinets struktur och funktion. I immunförsvarets finns&lt;br/&gt;&lt;br&gt; interaktioner som helt beror av proteins sockerkedjor.&lt;br/&gt;&lt;br&gt; Kroppens försvar är uppdelat i ett medfött och ett specifikt (adaptivt) immunförsvar.&lt;br/&gt;&lt;br&gt; Delarna av immunförsvaret kompletterar varandra när kroppen utsätts för en bakterie&lt;br/&gt;&lt;br&gt; eller virus. Det medfödda immunförsvaret har inget immunologiskt minne utan&lt;br/&gt;&lt;br&gt; attackerar strukturer som är gemensamma för flera mikroorganismer. Det adaptiva&lt;br/&gt;&lt;br&gt; immunförsvaret har förmågan att utveckla immunologiskt minne i form av celler som&lt;br/&gt;&lt;br&gt; producerar antikroppar specifikt riktade mot något främmande.&lt;br/&gt;&lt;br&gt; Antikroppar i blodet är glykoproteiner som kallas immunoglobulin G, IgG. Tidigare&lt;br/&gt;&lt;br&gt; forskning har visat att sockerkedjorna på IgG har stor betydelse för antikroppens&lt;br/&gt;&lt;br&gt; funktion. Om sockerkedjan saknas kan inte antikroppen binda till immunceller och då&lt;br/&gt;&lt;br&gt; förstörs inte den främmande mikroorganismen.&lt;br/&gt;&lt;br&gt; Grupp A streptokocker är en vanlig bakterie hos människor. Vi bär den på huden och&lt;br/&gt;&lt;br&gt; i svalget men den kan även orsaka halsfluss eller andra mycket allvarliga infektioner.&lt;br/&gt;&lt;br&gt; Hos grupp A streptokocker har forskare upptäckt enzymet EndoS. Ett enzym är ett&lt;br/&gt;&lt;br&gt; protein som förändrar andra proteiner och just enzymet EndoS klipper bort&lt;br/&gt;&lt;br&gt; sockerkedjan på antikroppen IgG. Antikroppen förlorar då sin förmåga att tillkalla&lt;br/&gt;&lt;br&gt; immunceller och förstöra bakterien. Streptokocker har flera andra enzymer och&lt;br/&gt;&lt;br&gt; proteiner som bidrar till att undkomma det mänskliga försvaret. Vad har egentligen&lt;br/&gt;&lt;br&gt; EndoS för betydelse vid infektioner av streptokocker?&lt;br/&gt;&lt;br&gt; I artikel 1 förändrade vi generna hos grupp A streptokocker och genererade en&lt;br/&gt;&lt;br&gt; EndoS-mutant, en bakterien som saknar EndoS men som har alla andra enzymer och&lt;br/&gt;&lt;br&gt; proteiner. Vi jämförde vår EndoS-mutant mot ursprungsbakterien och studerade hur sjuka möss blev i en modell av allvarlig streptokockinfektion. Det visade sig att&lt;br/&gt;&lt;br&gt; mössen blev lika sjuka och vi drog slutsatsen att EndoS inte ökar bakteriens förmåga&lt;br/&gt;&lt;br&gt; att orsaka sjukdom i möss. Vi genererade även en bakteriestam som utrycker stora&lt;br/&gt;&lt;br&gt; mängder av EndoS och vi såg då att mössen blev sjukare och bakterien mer&lt;br/&gt;&lt;br&gt; aggressiv. Vi tror att halten av enzymet EndoS i den lokala infektionsmiljön har&lt;br/&gt;&lt;br&gt; betydelse för hur allvarligt sjukdomsförloppet.&lt;br/&gt;&lt;br&gt; I artikel 2 upptäckte vi ett nytt enzym hos streptokocker som inte har studerats&lt;br/&gt;&lt;br&gt; tidigare. Genom att jämföra det okända proteinet med EndoS fann vi att proteinerna&lt;br/&gt;&lt;br&gt; vad 37% identiska, vilket är en låg siffra. Vi såg också att genen för det okända&lt;br/&gt;&lt;br&gt; enzymet fanns på exakt samma plats som EndoS i bakteriens DNA, och kallade&lt;br/&gt;&lt;br&gt; därför enzymet för EndoS2. Vi studerade enzymets aktivitet på IgG och upptäckte att&lt;br/&gt;&lt;br&gt; det klippte bort alla typer av sockerkedjor från antikroppen. Till skillnad från EndoS,&lt;br/&gt;&lt;br&gt; så klipper EndoS2 även bort socker från ett glykoprotein som är involverat i&lt;br/&gt;&lt;br&gt; inflammation. Slutsatsen blev att EndoS2 är ett nytt enzym från streptokocker som&lt;br/&gt;&lt;br&gt; klipper bort alla sockerkedjor från IgG.&lt;br/&gt;&lt;br&gt; Artikel 3, beskriver en studie där vi studerade en annan bakterie, Enterococcus&lt;br/&gt;&lt;br&gt; faecalis, och enzymet EndoE som liknar EndoS, men som klipper bort sockerkedjor&lt;br/&gt;&lt;br&gt; från flera glykoproteiner. Vi upptäckte att EndoE klippte bort socker från laktoferrin,&lt;br/&gt;&lt;br&gt; ett protein som finns i modersmjölk och som har antibakteriella egenskaper.&lt;br/&gt;&lt;br&gt; Laktoferrin utan sockerkedjor var mindre antibakteriellt och bakterierna överlevde&lt;br/&gt;&lt;br&gt; bättre i närvaro av laktoferrin. Vi såg också att enterokocker kunde använda det&lt;br/&gt;&lt;br&gt; bortklippta sockret som näringskälla.&lt;br/&gt;&lt;br&gt; Många nya läkemedel som utvecklas idag är biologiska läkemedel som består av&lt;br/&gt;&lt;br&gt; specifika antikroppar, oftast IgG. I artikel 4 jämförde vi den enzymatiska aktiviteten&lt;br/&gt;&lt;br&gt; av EndoS och EndoS2 på fyra antikroppar som används som läkemedel. Vi upptäckte&lt;br/&gt;&lt;br&gt; att EndoS2 klippte loss alla typer av socker medan EndoS lämnade en typ av socker&lt;br/&gt;&lt;br&gt; som kallas hög-mannos. Det finns indikationer på att antikroppar med mannossocker&lt;br/&gt;&lt;br&gt; fungerar sämre som läkemedel i kroppen. I artikeln presenterar vi en metod som&lt;br/&gt;&lt;br&gt; använder EndoS och EndoS2 för att snabbt och enkelt bestämma halten av mannos&lt;br/&gt;&lt;br&gt; på antikroppsläkemedel.&lt;br/&gt;&lt;br&gt; Artikel 5 handlar om en annan typ av antikropp, immunoglobulin E (IgE) och EndoS.&lt;br/&gt;&lt;br&gt; IgE är en typ av antikropp som har stor betydelse vid allergiska reaktioner. IgE är&lt;br/&gt;&lt;br&gt; precis som IgG, ett glykoprotein och bär flera sockerkedjor. Våra experiment visade&lt;br/&gt;&lt;br&gt; att EndoS även klipper bort socker från IgE och att antikroppen då fungerar sämre. I&lt;br/&gt;&lt;br&gt; en musmodell för allergi kunde vi genom att injicera EndoS, kraftigt minska den&lt;br/&gt;&lt;br&gt; immunaktivering som genom IgE leder till en allergireaktion. Våra resultat är preliminära, men kan tyda på att EndoS skulle kunna användas som läkemedel för&lt;br/&gt;&lt;br&gt; kraftiga allergier.&lt;br/&gt;&lt;br&gt; I denna avhandling visar vi att bakterier använder enzymer som är aktiva på&lt;br/&gt;&lt;br&gt; sockerkedjor på antikroppar för att undkomma immunförsvaret. Vi har upptäckt ett&lt;br/&gt;&lt;br&gt; nytt enzym hos streptokocker, EndoS2, och studerat betydelsen av EndoS vid&lt;br/&gt;&lt;br&gt; allvarlig streptokockinfektion. Vi visar att bakteriella enzymer kan användas i&lt;br/&gt;&lt;br&gt; bioteknisk industri för utveckling av antikroppsläkemedel. Slutligen, har vi upptäckt&lt;br/&gt;&lt;br&gt; att sockerkedjor på IgE har stor betydelse vid allergi och att EndoS skulle kunna&lt;br/&gt;&lt;br&gt; användas som läkemedel vi svåra allergiska reaktioner.&lt;br/&gt;&lt;br&gt; Bakteriers smarta sätt att undkomma immunförsvaret kan lära oss mycket om hur&lt;br/&gt;&lt;br&gt; immunförsvaret fungerar och hur bakterier orsakar infektion. Upptäckten av nya&lt;br/&gt;&lt;br&gt; enzymer kan även leda till applikationer i bioteknisk industri och eventuellt till&lt;br/&gt;&lt;br&gt; framtida läkemedel.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/54f7b922-32ef-4fce-9324-9e146221a262</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="SjAPgren_Thesis_for_publication.pdf">https://portal.research.lu.se/files/3040734/5050807.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">39178260</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Infection Medicine</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>IgG</topic> <topic>endoglycosidase</topic> <topic>Streptococcus pyogenes</topic> <topic>glycosylation</topic> <topic>EndoS</topic> </subject> <subject authority="lup"> <topic>Infectious Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-100-2</identifier> <identifier type="oldLupId">5050759</identifier> <part> <detail type="volume"> <number>2015:21</number> </detail> <extent unit="pages"> <total>143</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.biomedcentral.com/1471-2180/11/120</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.biochemj.org/bj/mobile/abstract.htm?x=/bj/455/1/bj4550107.xml</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0091035</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-03-13T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>54f7b922-32ef-4fce-9324-9e146221a262</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:54:26+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:54:26+02:00</recordDateApproved> </recordInfo> </mods>

Their low fuel consumption and high performance make them attractive, however, their associated pollutant emissions is a major drawback which represent a hazard for public health and the environment. &lt;br/&gt;&lt;br&gt; Therefore, the concentrations of the major pollutant species are regulated. &lt;br/&gt;&lt;br&gt; Soot, which to a large extent consists of carbon particles emanating from the combustion process, is the most problematic emission for diesel engines. &lt;br/&gt;&lt;br&gt; Soot emissions result from two competing processes, the formation and the oxidation. Diesel jets burn as lifted diffusion flames. The lift-off length, which is the distance between the injector and the base of the flame, is an important characteristic of diesel jets since it is strongly connected to the soot formation rate. In this thesis, three studies are devoted to the characterization of the flame stabilization of diesel jets in an engine environment and in a high-pressure combustion vessel. A nonlinear regression model, based on a previous empirical correlation developed in a combustion vessel, is proposed to describe the lift-off length of diesel jets in a particular engine environment. &lt;br/&gt;&lt;br&gt; The novelty of this model, apart from being based on a systematic study of lift-off lengths in an engine environment, is the integration of two variables coupled to important engine specific features, the jet-jet and jet-flow interactions.&lt;br/&gt;&lt;br&gt; A fourth study compares the respective impacts of soot formation and soot oxidation on soot emissions in an engine. The efficiency of the soot oxidation process is found to have the dominating effect on soot emissions.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Upstream of the lift-off region, the penetration length of the liquid-phase fuel is another important characteristic of diesel sprays. This parameter is linked to the spray formation and to the fuel-air mixing and thereby to the entire combustion process.&lt;br/&gt;&lt;br&gt; Two studies on the liquid penetration of diesel jets are presented in the second part of this thesis. In the first one, an injection strategy to avoid wall-wetting of late post-injections used for the regeneration of diesel particulate filters is demonstrated. In the second study, the effect of jet-jet interactions on the liquid fuel penetration of diesel jets is investigated. The liquid fuel penetration length is increased with a reduction of the spacing between the jets.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis, optical engines are used to carry out the experimental investigations. In these engines, few metal parts are replaced with a transparent material such as quartz to obtain a visual access into the combustion chamber. High-speed imaging and laser-based diagnostics are combined to capture the time-evolution of the lift-off length and the transient liquid penetration of the fuel.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Dieselmotorn lanserades för mer än ett sekel sedan och är nu den mest använda motorn inom Europas transportsektor. Detta beror framför allt på dess låga bränsleförbrukning och höga effekt. Avgasutsläppen är dieselmotorns största nackdel eftersom dessa biprodukter från förbränningen har negativa effekter både på folkhälsan och miljön. Därför regleras utsläppen genom lagstiftning. De tillåtna utsläppsnivåerna sänks dramatisk vid varje nytt lagstiftningstillfälle, vilket driver motortillverkare att hitta nya teknologiska lösningar och samtidigt motorforskningen att förbättra förståelsen av de mekanismer som ligger bakom emissionsbildningen i cylindern.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det mest problematiska utsläppet från dieselmotorer är sot, som till största delen består av kol. Sot bildas när bränslet förbränns med ett underskott av luft. Bränslets kolatomer kan då inte omvandlas till koldioxid (CO\textsubscript{2}) utan bildar istället kolpartiklar. Sotutsläppen är svåra att prediktera med de beräkningsverktyg (CFD) som idag används vid utveckling av förbränningssystem för dieselmotorer. En av de processer som är viktiga att förstå är flammans stabilisering på att visst avstånd från insprutaren (den så kallade lift-off längden eller ”lyfthöjden”). Den är central för sotbildningen i en brinnande dieseljet eftersom den bestämmer hur mycket luft som kan blandas med bränslet innan det antänds. Den bestämmer med andra ord hur stort luftunderskottet blir under förbränningen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Lyfthöjden har främst studerats i spraykammare, där en ensam dieseljet sprutas in i en mycket stor volym luft. Studier i optiska motorer i Lund har visat att spraykammarresultat inte kan överföras direkt till motorer. Detta beror på att spraykammare inte återskapar en rad av de förhållanden som påverkar förbränningen i en motor. I motorn interagerar till exempel flera sprayer med varandra och med förbränningsrummets väggar. Idag finns alltså inget giltigt valideringsunderlag för CFD-modeller vad avser flammans stabilisering i motorer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den här avhandlingen består av två delar. Den första fokuserar på att beskriva lyfthöjden i motormiljö och den andra fokuserar på det vätskeformiga bränslets utbredning i förbränningsrummet. En experimentell databas över lyfthöjder har byggts upp från mätningar i en optisk motor, vilket är en motor som försetts med ”fönster” genom vilka förbränningsförloppet kan studeras. En rad parametrar varieras tillsammans med närheten mellan sprayerna och luftens flödesmönster i cylindern. Resultaten har sammanställts i en empirisk modell av lyfthöjden som kan användas för validerings- och kalibreringsunderlag av CFD-modeller. Bränslets kemiska egenskaper har också en effekt på lyfthöjden och sotbildningen. Därför studerades även flammans stabilisering med två ovanliga bränslen i en spraykammare. Syftet var dels att förstå flamstabiliseringsprocessen och dels att se om dessa bränslen kan användas i dieselmotorer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det mesta av det sot som bildas under förbränningen oxideras i cylindern innan avgasventilen öppnas. Därför är det viktigt att förstå hur oxidationsprocessen påverkar utsläppen. En korrelationsanalys av motordata bekräftar i den här avhandlingen att oxidationsprocessen är det viktigaste verktyget för att minska sotutsläppen. Det är dock fortfarande viktigt att förstå lyfthöjden och hur den påverkar sotbildningprocessen. Då utsläppen är skillnaden mellan den mängd sot som bildas och den mängd som oxideras, måste man ju ha kunskap om båda processerna för att kunna prediktera exakt hur stora utsläppen blir.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I andra delen av avhandlingen presenteras två studier om vätskans utbredning i bränslesprayerna. Den första är kopplad till ett praktiskt problem som uppstår när partikelfällan regenereras i en bil, det vill säga att de sotpartiklar som fastnat i fällan bränns ur. Speciella insprutningsstrategier används vid regenereringen och dessa gör det svårt att undvika att bränslet träffar cylinderväggen. I en optisk motor kan man direkt studera om bränslet förångas innan det når väggen. I detta fall kunde den optiska motorn användas för att ta fram en insprutningsstrategi som undviker väggvätning. Den sista delen av avhandlingen är en studie som beskriver hur interaktioner mellan sprayerna påverkar vätskans utbredning i sprayen, vilket inte har så stor praktisk betydelse men bidrar till den grundläggande förståelsen av de processer som styr spraybildningen.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/95ffa3d3-5a8f-44f2-ba20-ae26673f6537</url> </location> </relatedItem> <originInfo> <publisher>Division of Internal Combustion Engines</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>high-speed imaging</topic> <topic>liquid penetration</topic> <topic>lift-off length</topic> <topic>soot</topic> <topic>optical engine</topic> <topic>Diesel sprays</topic> </subject> <subject authority="lup"> <topic>Other Mechanical Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7623-327-6</identifier> <identifier type="oldLupId">5364752</identifier> <part> <extent unit="pages"> <total>99</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-29T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>95ffa3d3-5a8f-44f2-ba20-ae26673f6537</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:54:32+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:54:32+02:00</recordDateApproved> </recordInfo> </mods>

An integral part of these dynamic processes is the interplay between the cells and their environment, i.e. the extracellular space. Complex polysaccharides, such as dermatan sulfate play a key role in these processes. &lt;br/&gt;&lt;br&gt; Dermatan sulfate is a long linear polysaccharide of a repeating disaccharide unit consisting of N-acetylgalactosamine and glucuronic acid/iduronic acid. Formation of iduronic acid through epimerisation of glucuronic acid is a key modification in dermatan sulfate biosynthesis. In the present thesis two enzymes have been identified that catalyzes this reaction, i.e. DS-epimerase 1 and 2. By using fold-recognition modeling a structural model was obtained for DS-epimerase 1, which enabled characterization of the active site of the enzyme with mutational analysis. &lt;br/&gt;&lt;br&gt; A feature of a dermatan sulfate chain is the presence of sequences of iduronic acid containing disaccharides separated by stretches of glucuronic acid containing disaccharides. The former are also commonly associated with sulfation in the 4-O-position of N-acetylgalactosamine suggesting that there is interplay between sulfation and epimerization. In this thesis it is shown that both epimerases are simultaneously needed together with the sulfotransferase D4ST-1 to generate these types of domains. Interestingly, 4-O-sulfated iduronic acid blocks constitute the binding site for several growth factors, including fibroblast growth factor 2. Through this binding, dermatan sulfate can sequester the growth factor in the extracellular matrix and regulate the availability of the growth factor at the cell surface. Dynamic changes in dermatan sulfate structure thus offers a way to fine-tune signaling. In this thesis evidence is presented that common growth factors such as transforming growth factor-β, platelet derived growth factor and epidermal growth factor have the ability to regulate both epimerase activity and gene expression of several sulfotransferases, including D4ST-1, which results in reduction of 4-O-sulfated iduronic acid blocks.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2138de36-1c2b-4d93-aa7b-04e545956d30</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa_Benny_pacheco.pdf">https://portal.research.lu.se/files/3042388/1260597.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1603038</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Basic Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-66-8</identifier> <identifier type="oldLupId">1260590</identifier> <part> <detail type="volume"> <number>2008:113</number> </detail> <extent unit="pages"> <total>141</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.jbc.org/cgi/content/full/281/17/11560</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://glycob.oxfordjournals.org/cgi/content/full/15/12/1277</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-11-20T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>2138de36-1c2b-4d93-aa7b-04e545956d30</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:54:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:54:38+02:00</recordDateApproved> </recordInfo> </mods>

The first paper focuses on characterizing the bone and cellular phenotype in the adult osteopetrotic mouse model and find that bones, are both bigger and, in contrast to the endogenous oc/oc mouse model, stronger in mice transplanted with osteopetrotic stem cells compared to wild type transplanted mice. In the second paper we compare the osteoclast-rich osteopetrotic oc/oc transplanted model to adult mice transplanted with stem cells from the osteoclast-poor RANK KO mouse, and find that maintaining non-resorbing osteoclasts in vivo increases bone formation. In the third paper we investigate the role of bone matrix, cell stage and resorptive function on osteoclast mediated anabolic signaling. In paper IV human stem cells from patients with ARO were investigated and we provide the first proof-of-principle for lentiviral mediated correction of resorptive function in CD34+ derived osteoclasts from ARO patients.&lt;br/&gt;&lt;br&gt; The results can be devided into two exciting branges. Data obtained in the adult osteopetrotic mouse models encourage further development of molecules targeting the acidification process in osteoclasts when treating low bone mineral density diseases. Furthermore, the correctional results in the ARO patient cells are very promising, and will serve as basis for further development of clinical gene therapy of osteopetrosis.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; My PhD thesis has focused on increasing the understanding of the osteoclasts, the cells responsible for degradation of bone, by studying the rare hereditary disease autosomal recessive osteopetrosis (ARO). ARO is present already at birth and is caused by mutations affecting the osteoclasts ability to degrade bone. Non-functional osteoclasts lead to dramatic increases in bone thickness affecting bone marrow, blood vessels, and nerves due to having smaller cavities in the skeleton. Despite the increase in bone mass, the bones are weak and brittle because of how the bones are molded during growth, and fractures often occur. In almost half the cases, the disease is caused by mutations in the gene called TCIRG1, which encodes a protein important in the degradation of calcium in bone. As osteoclasts come from blood stem cells, the disease can be corrected by bone marrow transplantation, replacing sick stem cells with healthy cells from a donor. However, this treatment is risky and is highly dependent on a matching donor. Without bone marrow transplantation the disease is fatal within five years of birth.&lt;br/&gt;&lt;br&gt; Under normal circumstances the osteoclast mediated bone degradation process leads to release of signals that direct new bone formation by specialized cells called osteoblasts. In ARO patients these osteoclast derived signals are maintained despite the lack of bone degradation, suggesting that simply the osteoclasts being present may be enough for bone formation. A great effort has been put into identifying these osteoclast derived signals as they may lead to new treatments for patients with too little bone, such as osteoporosis.&lt;br/&gt;&lt;br&gt; In the first two papers we developed an adult mouse model with osteopetrosis to investigate how signals from non-functional osteoclasts affected bone formation. We induced osteopetrosis by transplanting stem cells from osteopetrotic mice, with defects in the mouse version of TCIRG1, into normal adult mice. The healthy osteoclasts are thereby replaced by non-functional osteoclasts and the mice develop a mild form of osteopetrosis. In paper I we found that these “osteoclast-rich” osteopetrotic mice have increased bone mass and surprisingly increased bone strength compared to control mice.&lt;br/&gt;&lt;br&gt; In Paper II we compared the osteoclast-rich model to an osteoclast-poor model. For this we instead used stem cells from a mouse model which has a mutational defect in a gene crucial for osteoclast development. Comparing these two types of osteopetrosis in mice, we found that bone formation was increased in osteoclast-rich osteopetrotic mice compared to their osteoclast-poor counterparts. These findings suggest that blocking bone degradation, while keeping osteoclasts, maintains the signals directing bone formation. A molecule blocking the osteoclasts ability to degrade bone but without removing the cell itself, may be interesting as potential treatment for low bone mass diseases such as osteoporosis.&lt;br/&gt;&lt;br&gt; In paper III we used different ways of modifying osteoclast function to investigate how the release of signals from osteoclasts, directing bone formation is affected by these changes in various osteoclast related functions. We also used osteoclasts from ARO patients to show that signals are still being released directing bone formation despite their lack of bone degradation. The studies indicate that the signals are both dependent on how old the osteoclast is, and what type of bone the osteoclast is degrading.&lt;br/&gt;&lt;br&gt; Blood stem cells can renew themselves and produce all the different kinds of blood cells in the blood throughout a lifetime. By correcting these cells one can change the function of all osteoclasts that are to be made. The principle of gene therapy is to insert the normal functional gene into a cell having dysfunctional gene. This may result in the patient’s ability to produce the correct functional protein themselves. &lt;br/&gt;&lt;br&gt; In Paper IV we used a modified HIV-virus as a tool to insert the correct functioning TCIRG1 gene into human ARO blood stem cells. We found that the corrected cells expressed the functional protein and that function was almost fully restored in these osteoclasts, as could be measured by the release of degradation products such as calcium and collagen fragments.&lt;br/&gt;&lt;br&gt; In summary these studies have increased the understanding of ARO and the osteoclast related defects causing this disease as well as taken a step towards gene therapy as a treatment for this ARO. The experiments have also shed light on the important regulation undertaken by the osteoclasts in the maintenance of bone, and findings suggest that targeting the osteoclasts ability to degrade bone without removing the osteoclasts may be a novel target for treatment of bone turnover diseases.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8a508660-eef5-4b36-b96d-1724232ed5f6</url> </location> </relatedItem> <originInfo> <publisher>Division of Molecular Medicine and Gene Therapy</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Osteoclast</topic> <topic>Osteopetrosis</topic> <topic>Osteoporosis</topic> <topic>Bone</topic> <topic>Hematopoiesis</topic> <topic>Gene Therapy</topic> <topic>Mouse Models</topic> <topic>oc/oc</topic> <topic>RANK KO</topic> </subject> <subject authority="lup"> <topic>Hematology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-040-1</identifier> <identifier type="oldLupId">4647714</identifier> <part> <detail type="volume"> <number>2014:111</number> </detail> <extent unit="pages"> <total>85</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-10-10T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>8a508660-eef5-4b36-b96d-1724232ed5f6</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:54:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:54:40+02:00</recordDateApproved> </recordInfo> </mods>

Though effective in alleviating disease symptoms in large cohorts of patients, these treatment options have the major drawback of being non-curative. Currently, bone marrow transplantation (BMT) from an immune compatible donor is the only corrective therapy for both GD type I and DBA. However, donor availability and standard BMT procedures are associated with an increased risk of morbidity and mortality. Gene therapy, entailing ex vivo genetic correction of autologous hematopoietic stem/progenitor cells (HSPCs) by retroviral vectors, has the potential of becoming a future therapeutic option for both GD type 1 and DBA patients unresponsive to conventional therapies. Gene therapy of autologous HSPCs circumvents the need for finding an HLA-matched donor and could potentially require a less rigid pre-conditioning protocol, thereby reducing risks associated with allogeneic BMTs. We have investigated self-inactivating (SIN) lentiviral vectors with cellular promoters in a murine disease model displaying clinical GD type I symptoms (Paper I). From our studies we conclude that a modest increase of GCase activity by enforced expression of GBA, primarily in tissue macrophages, effectively reverses pathophysiological symptoms in GD type 1 mice. Furthermore, we observe a relatively safe integration profile of the lentiviral vectors. Taken together, this provides support for the development of a clinical gene therapy protocol for GD type 1 patients using similar vectors. In Paper II we have evaluated a non-myeloablative conditioning protocol for autologous BMTs for treatment of DBA by employing a murine disease model with downregulated expression of ribosomal protein S19 (RPS19), the most frequently mutated gene in DBA patients. We show efficient reversal of key clinical hematopoietic symptoms after syngeneic BMTs in both sub-lethally and non-irradiated recipients with RPS19 deficiency. A reduced intensity conditioning protocol would be highly valuable in a clinical gene therapy setting for DBA, reducing risks associated with full myeloablation preceding BMT. In Paper III we report the finding of a novel regulator of adult HSCs, the Schlafen-2 protein. In extensive in vivo studies we determine that adult murine HSCs with mutated Schlafen-2 protein have reduced regenerative capacity. Identification of factors essential for HSC regulation aids not only in our basic understanding of hematopoiesis, but also plausibly to improved future HSC-based treatments. &lt;br/&gt;&lt;br&gt; In summary, this thesis focuses on translational and basic research evaluating novel cell and gene therapeutic strategies for GD type 1 and DBA.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/412c1c64-0818-4b0e-b427-76262d10f56c</url> </location> </relatedItem> <originInfo> <publisher>Division of Molecular Medicine and Gene Therapy</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Gaucher disease</topic> <topic>lentiviral vectors</topic> <topic>gene therapy</topic> <topic>Diamond-Blackfan anemia</topic> <topic>hematopoietic stem cells</topic> <topic>bone marrow transplant</topic> <topic>Schlafen-2</topic> </subject> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-171-2</identifier> <identifier type="oldLupId">8033318</identifier> <part> <detail type="volume"> <number>2015:92</number> </detail> <extent unit="pages"> <total>87</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-10-23T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>412c1c64-0818-4b0e-b427-76262d10f56c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:54:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:54:40+02:00</recordDateApproved> </recordInfo> </mods>

The practice of public health incorporating medicine’s cognitive contents along with contributions from other fields of human activities is basically a moral enterprise. It is important that limitations from the whole continuum of these interventions are recognized to retain credibility. The changing demands resulting from the dynamics of global altering societies, as well as new priorities due to medico-technical developments, must also be acknowledged. &lt;br/&gt;&lt;br&gt; An epistemic expansion of the evidence-base for public health actions is argued for. ‘Nomothetic’ and ‘idiographic’ are suggested as more neutral concepts instead of ‘quantitative’ and ‘qualitative’ for characterizing the methodological approach. Assumptions about the nature of medical knowledge have from the beginning had an explicit preference for empirical evidence. Natural science is often taken as congruent with medical science, a thought style challenged in the history of public health and from outside the discipline. An integration of nomothetic and idiographic kinds of knowledge, i.e. a true research synthesis, is relevant as evidence-base for public health actions and also needed for a valid ethical analysis in context. In each of the presented four cases, the measles vaccination programme, a hypothetical mass screening for prostate cancer with prostate-specific antigen, a hypothetical risk group screening for Herpes virus type 2 and screening for postpartum depression, the evidence-base is discussed in its Swedish context and with a critical eye to the assumed validity of underlying assumptions. The role of history, collaboration over disciplinary boundaries and virtues, especially prudence, is highlighted as important for attaining a critical distance to what is described as facts. &lt;br/&gt;&lt;br&gt; The casuistic approach is necessary to visualize the complexity and the inherent and sometimes hidden ethical problems of the specific interventions. The principles autonomy, beneficence, non-maleficence, justice and the choice of affected persons then give ethical meaning to the otherwise factual circumstances.The suggested framework for analysis does not involve a general theory of values but is enacted in the middle ground between theories and the details of policy and practice. It is one of many possible ways to structure ethical deliberations. The conclusions arrived at are that measles vaccination must remain voluntary to vouchsafe autonomy and credibility; that screening for prostate cancer and Herpes virus type 2 with available tests come with non-acceptable side-effects especially invoking the principles of beneficence, non-maleficence and justice as solidarity. The EPDS screening for postpartum depression at is questionable. The ethical reservations mainly concern the principles of autonomy and beneficence but also how professional knowledge is inundated by values unwittingly having an impact on a weak evidence-base. An analogy approach is used as a complement to illustrate how demands differ, when new methods or technologies are introduced in health care.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5795cae0-1798-4bc8-b08f-2fe9b2e01146</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="krantz.pdf">https://portal.research.lu.se/files/3043438/1243742.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">588277</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Medical Ethics, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Herpes virus type 2</topic> <topic>prostate cancer</topic> <topic>measles</topic> <topic>evidence-based medicine</topic> <topic>casuistry</topic> <topic>virtues</topic> <topic>principlism</topic> <topic>values</topic> <topic>ethics</topic> <topic>vaccination</topic> <topic>Public health</topic> <topic>screening</topic> <topic>postpartum depression.</topic> </subject> <subject authority="lup"> <topic>Medical Ethics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-53-8</identifier> <identifier type="oldLupId">1242607</identifier> <part> <detail type="volume"> <number>2008:100</number> </detail> <extent unit="pages"> <total>104</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-17T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>5795cae0-1798-4bc8-b08f-2fe9b2e01146</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:54:49+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:54:49+02:00</recordDateApproved> </recordInfo> </mods>

The cause of these motor symptoms is the selective loss of mesencephalic dopaminergic (mesDA) neurons, located in the substantia nigra (SN). These neurons project axons to the striatum where they release dopamine, a neurotransmitter that controls voluntary movement. Current drug treatments restore the lost dopamine, while initially efficacious, the beneficial effects wear off resulting in severe side effects. Thus, there is a clear requirement for alternative therapeutic options. &lt;br/&gt;&lt;br&gt; One such idea is cell replacement therapy (CRT). CRT aims to replace neurons that have degenerated in PD, with donor cells that have the potential to functionally re-integrate into the host circuitry. This involves transplantation of developing midbrain cells from aborted fetuses, (the part that form mesDA neurons), into the striatum of a PD patient. Clinical trials have demonstrated that CRT can provide long-lasting, significant clinical benefit. Although some patients do not respond as favourably. We still do not know what specific factors contribute to the success in transplantation i.e. what cells are responsible for motor recovery? Can the transplants reform damaged neuronal circuitry? Use of human fetal tissue raises several ethical issues, but are there alternative cell sources that can substitute effectively? The aim of this thesis was to understand how particular factors such as neuronal content, placement and cell source, affect functional outcome after transplantation into the rodent brain.&lt;br/&gt;&lt;br&gt; In paper №1, I detail the neurodegenerative and behavioural outcomes in a mouse lesion model of PD, which can be used as a platform for the development of novel therapeutic strategies. I also describe the development of a novel behavioural task that is predictive of mesDA neuron cell loss in mice. Previously, it was thought that transplanted neurons could not extend axons over long distances rendering transplantation into the SN a non-viable approach. In paper №2, I describe how mesDA neurons transplanted in the adult SN of a PD mouse model, extended axons across millimetres into the striatum, functionally reforming the nigrostriatal pathway. In paper №3, I also identify the specific mesDA population (A9) that is critical for functional recovery, with transplants that lack A9 neurons failing to improve motor recovery. A potentially pre-clinical aspect of this thesis is detailed in paper №4 where I describe a robust protocol for the generation of functional mesDA neurons from human embryonic stem cells that are functional in a rat model of PD. No evidence of tumour formation was observed in the transplanted animals, a major concern when utilising a pluripotent cell source.&lt;br/&gt;&lt;br&gt; Through understanding functional recovery in terms of neuronal subtype and connectivity, the work presented in this thesis aims to bring the prospect of CRT closer to the clinic, I also describe the generation of a very promising alternative cell source that could rival fetal tissue. Together this work contributes to making CRT a reality for the treatment of PD.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Patienter som drabbats av Parkinsons sjukdom (PD) saknar förmågan att medvetet kontrollera sina rörelser. Livslång medicinering krävs, vilket lindrar symptomen och leder till att rörelsemönstret förbättras, men med varierad effektivitet. Trots att de läkemedel (t ex L-DOPA) som finns tillgängliga idag har fantastisk effekt, minskar deras effektivitet i takt med att sjukdomen fortgår och ger istället en högre grad bieffekter. Förutom medicinering finns det idag få andra möjligheter till behandling av sjukdomen och efterfrågan på nya behandlingsformer är stor. Vi vet att det är de dopaminerga nervcellerna i mellanhjärnan (mesDA nervceller), vilka ansvarar för kontrollen av rörelser, som dör av då PD fortskrider. Kan det därför vara ett bra alternativ till behandling att försöka ersätta dessa celler?&lt;br/&gt;&lt;br&gt; Ett lovande och framgångsrikt tillvägagångssätt har visat sig vara att ta ut den del av hjärnan som ger upphov till mesDA nervceller från donerade aborterade foster, och sedan injicera dessa friska nervceller till patienter med PD. Resultat från dessa kliniska studier har visat att cellerna kan överleva i minst 14 år och att vissa patienter helt har kunnat sluta sin medicinering med L-DOPA. Dessvärre har inte alla patienter reagerat lika positivt på behandlingen och för vissa patienter har det inte blivit någon förbättring alls. Det finns också ett etiskt dilemma i och med användandet av celler från aborterade foster och om cellterapi ska kunna bli ett alternativ till behandling i stor skala måste man undersöka alternativa sätt att tillhandage dessa typer celler. Arbetet som presenteras i denna avhandling har till uppgift att ge förståelse för vilka faktorer som påverkar funktionaliteten av transplanterade mesDA nervceller i ett preklinisk sammanhang, d.v.s. var nervcellerna är placerade, vilka nervceller som är viktiga för återhämtning och vilka celler som bör användas. &lt;br/&gt;&lt;br&gt; Det typiska är att cellerna transplanteras in i striatum, vilket är det område där cellerna och dopaminet har funktionella effekter. Vi upptäckte i studier på möss att om mesDA celler transplanteras in i mellanhjärnan, där de i vanliga fall är placerade i en frisk hjärna kan cellerna innervera striatum flera millimeter bort, något som man tidigare trodde var omöjligt. Vi undersökte också vilka typer av mesDA nervceller som ger förbättring och återhämtning efter transplantation. Det visade sig att om mesDA nervceller som associeras med motorisk kontroll (A9) saknades förbättrades inte det motoriska mönstret i de djur som transplanterats. En sista fråga som behandlas i denna avhandling är huruvida man kan använda andra källor för att generera rätt typ av mesDA nervceller än fetal vävnad, så som humana stamceller. I vår studie kom vi fram till att det är möjligt att generera mesDA nervceller från humana stamceller med egenskaper förvånansvärt lika de i ett foster. De mesDA nervceller som kommer från stamcellerna kan överleva en transplantation, bildar inga tumörer, och bidrar till förbättrad funktion.&lt;br/&gt;&lt;br&gt; Arbetet i denna avhandling har bidragit till en ökad förståelse för hur transplantation av mesDA nervceller ger sin positiva effekt och vilka faktorer som bör tas hänsyn till om användandet av andra källor än fetal vävnad, så som stamceller, är önskvärt. Förhoppningen med detta arbete är att ta cellterapi som behandlingsform för Parkinsons sjukdom ett steg närmare kliniken.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Patients that suffer from Parkinson’s disease (PD) have lost the faculty to consciously control their movement. Lifelong medication is needed, which relieves symptoms, but often with different efficiencies. Although these drugs, namely L-DOPA, provide amazing clinical benefit: as the disease progresses and the drug continues to cause more side effects, the mobility of the patient decreases. Apart from medication, there are little clinical options available to patients, therefore there is a clear need for new therapies. We know that dopamine neurons of the midbrain (mesDA neurons) are responsible for controlling movement, and that these cells are lost during the progression of PD. Therefore, might it be feasible to try and replace these lost cells?&lt;br/&gt;&lt;br&gt; The most successful approach is called cell replacement therapy. This involves taking the region of the developing brain that will form mesDA neurons (from a fetus donated from elective abortions) and grafting these developing neurons into a patients brain. Initial clinical trials have proved that patients can survive with functioning grafts for at least 14 years and in some cases stop taking L-DOPA altogether. However this is the best-case scenario and not all patients respond to the same extent. Additionally, it is important for the widespread application of cell replacement therapy to consider alternative cell sources for large-scale application, given the ethical implications arising from the source of the tissue. The work presented in this thesis aims to understand what factors affect functionality of transplanted mesDA neurons in a preclinical setting; namely where the neurons are placed, what neurons are responsible for recovery and what cells are used.&lt;br/&gt;&lt;br&gt; In order to ensure a functional effect, cells are typically transplanted into their destination or target structure (the striatum). In studies in mice we have discovered that if mesDA cells are transplanted into their site of origin (the midbrain), they can make functional connections to the striatum which is several millimetres away. This phenomenon is something that was previously believed to be unachievable. The next question was to understand what type of mesDA neuron is responsible for mediating motor recovery after transplantation. Here we found that if the mesDA neurons associated with motor control (A9) are missing from transplants, a PD animal model does not recover motor function. The final question addressed in this thesis is: can use cell sources other than human fetal tissue (i.e. human stem cells), to generate a true mesDA neuron. We found that we can generate mesDA neurons from human embryonic stem cells that are remarkably similar to their fetal counterparts. The stem cell derived mesDA neurons can survive transplantation, not generate tumours, and provide functional benefit.&lt;br/&gt;&lt;br&gt; The work in this thesis has contributed to advancing our understanding of how transplants of mesDA neurons elicit their beneficial effects, and what factors we should consider when using alternative cell sources such as stem cells. It is hoped that this work brings us closer towards a cell replacement therapy for Parkinson’s disease.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/74dbbb7c-8b19-4e17-bbb8-3613b7140800</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="20120102_Shane_Grealish_Thesis.pdf">https://portal.research.lu.se/files/3044037/2273303.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1852056</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Neurobiology</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>mouse behaviour</topic> <topic>6-hydroxydopamine</topic> <topic>human embryonic stem cells</topic> <topic>fetal tissue</topic> <topic>connectivity</topic> <topic>midbrain dopamine neuron subtype</topic> <topic>cell transplantation</topic> <topic>Parkinson’s disease</topic> </subject> <subject authority="lup"> <topic>Medical and Health Sciences</topic> <topic>Basic Medicine</topic> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-66-6</identifier> <identifier type="oldLupId">2273302</identifier> <part> <detail type="volume"> <number>2012:4</number> </detail> <extent unit="pages"> <total>180</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-01-27T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>74dbbb7c-8b19-4e17-bbb8-3613b7140800</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:00+02:00</recordDateApproved> </recordInfo> </mods>

The AR gene contains a polymorphic CAG repeat, encoding a stretch of glutamines, affecting the transcriptional activity of the AR. Prostate specific antigen (PSA) is a downstream target and is commonly used in the screening of prostate cancer. The relationship between CAG number and male reproductive health has been suggested to be modulated by persistent organic pollutants (POPs). Humans are exposed mainly through food intake, but also from industrial processes and cigarette smoking. The dioxin-like POPs exert their effect through the aryl hydrocarbon receptor (AhR), shown to interact with the AR. The aims were to study the role of the CAG polymorphism on; AR activity and expression in the absence or presence of POPs; PSA concentration in serum and tissue; and reproductive parameters and hormones in men. It was also elucidated whether the CAG number could modify the effect of cigarette smoking on reproductive characteristics in men. The transactivation assay included a reporter gene with a human androgen responsive promoter. Cells were transfected with vectors having CAG numbers of 16, 22 or 28, representative of the human range. To explore the association between CAG number and reproductive outcome, an unprejudiced spline regression model with CAG number as a continuous variable was used, as well as a stratified model and in case of linear pattern, CAG number was investigated in a linear regression model. &lt;br/&gt;&lt;br&gt; We found that the CAG variant with the median length had the highest AR activity, shown both in cell lines and prostate tissue, and as highest PSA concentration in younger and older men. The unprejudiced statistical analysis gave a better picture of the relationship between CAG number and reproductive outcomes, demonstrating a CAG-dependent effect on hormone levels. The CAG repeat also had a cell line- and dose-dependent modulating effect of POPs on AR activity and was negatively associated with semen volume in smoking men. &lt;br/&gt;&lt;br&gt; To conclude, the median AR CAG number had the highest activity in vivo and in vitro. This pattern consisted even in the presence of POPs, indicating a stronger resistance for the median CAG length to these compounds compared to less common variants. The CAG number was also associated with reproductive hormone regulation and might modify the susceptibility of current cigarette smoking on semen volume in young men.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; De senaste årtiondena har det diskuteras om det finns anledning till oro när det gäller mannens reproduktionsfunktion. Vissa forskningsresultat tyder på att spermieantalet har minskat och fler män har diagnostiserats med testikelcancer och medfödda missbildningar av könsorganen än tidigare. Om detta beror på genetiska faktorer, livsstil eller miljöfaktorer, eller alla tre är ännu inte känt. Orsaken till symtomen har föreslagits vara hormonstörande ämnen, även kallade miljögifter. Många av dessa ämnen är fettlösliga och svårnedbrytbara. De ackumuleras i näringskedjan och även om många av ämnena är förbjudna i de flesta länder finns de kvar i miljön. Människor utsätts huvudsakligen genom mat, men också efter industri-utsläpp, cigarettrök och malariabehandling. &lt;br/&gt;&lt;br&gt; Vissa av dessa ämnen kan ”härma” de manliga könshormonerna; testosteron (T) och 5α-dihydrotestosteron (DHT) och därmed rubba hormonbalansen, eller bryta ner hormonernas mottagare androgenreceptorn (AR). Hormonerna är nödvändiga för normal könsutveckling, pubertet och för reglering av spermieutveckling hos män. De binder till AR, som förmedlar den hormonella effekten via reglering av andra gener. Fel i receptorn resulterar i dålig ”signalöverföring” och kan orsaka sjukdomar med allt från allvarliga missbildningar, som medför att det kan vara svårt att bestämma barnets kön, till lättare varianter som manlig infertilitet. &lt;br/&gt;&lt;br&gt; AR-genen ligger på X-kromosomen, vilket innebär att män bara har en kopia medan kvinnor har två. Detta leder till att genmutationer eller förändringar av AR-proteinets funktion oftast drabbar män. I AR-proteinet finns en sträcka med repeterande DNA-baser som varierar mellan individer och populationer. Dessa baser, CAG, kodar för aminosyran glutamin, och antalet repetitioner har betydelse för proteinets funktion. &lt;br/&gt;&lt;br&gt; En studie på män från fyra länder som var olika utsatta för miljögifter, visade att de som var mest exponerade för PCB (polyklorinerade bifenyler) och hade en viss genotyp dvs. genetisk uppsättning av CAG-repetitioner, hade färre spermier än de som var mindre exponerade. Då kan man fråga sig om dessa män har en ökad känslighet för miljögifter och om de kanske kan förändra funktionen av AR. Detta undersöktes i ett cellsystem med njurceller från apa, vilka inte har någon egen produktion av AR. Vi kunde därför föra in tre olika genotyper för att undersöka vad som hände med AR-proteinets aktivitet när vi tillsatte PCB och DDT, separat eller tillsammans, i olika koncentrationer i närvaro av könshormonet DHT. Vi såg att motsvarande genotyp som i studien på män, var den som påverkades mest av DDT. Mixen hade störst påverkan på en av de andra genotyperna. När man tillsatte en extremt hög koncentration av mixen försvann skillnaderna mellan genotyperna och AR-aktiviteten minskade drastiskt. Vi såg även att den genotyp som är vanligast bland vita män (22CAG) hade högst aktivitet i närvaro av DHT, både med och utan miljögifterna. De vanligast förekommande genotyperna har visat sig att ha bäst proteinfunktion och har därför föreslagits vara bevarade genom evolutionen, kanske genom att också vara mest motståndskraftiga mot främmande ämnen. Mönstret var likadant när vi testade genotyperna i prostatacellinjer, med och utan att vara angripna av cancer, först enbart med DHT och sedan med dioxinvarianten, 2,3,7,8 tetrachlorodi-benzo-p-dioxin (TCDD). &lt;br/&gt;&lt;br&gt; Män som har varit högutsatta för TCDD har visat sig ha en ökad risk för prostatacancer (PCa). Dessa män har även färre CAG-repetitioner i AR, vilket också har relaterats till risken för PCa. Vi fann att genotypen med färre CAG-repetitioner påverkades mest av TCDD i celltypen utan cancer, vilket gör fyndet intressant. Effekten av TCDD förmedlas genom arylhydrocarbonreceptorn (AhR), även kallad dioxinreceptorn, som kan interagera med AR. Man måste dock ha i åtanke att det är ett cellsystem och i en människa kan kroppen kompensera för en sämre proteinfunktion med att slå på ökad hormonproduktion och jämna ut effekten så länge kroppen fungerar normalt. &lt;br/&gt;&lt;br&gt; Förutom effekten av miljögifter har vi studerat om en mål-gen för AR-proteinet, prostataspecifik antigen (PSA), som används för att diagnosticera PCa, ändras i blodet beroende på genotyp. Vi såg att män med 22CAG-repetitioner hade högst PSA jämfört med män med andra varianter. Detta stämde även överens med mängden PSA-protein i vävnad från mänsklig prostata. Denna studie kan, om den upprepas i ett större material, ha betydelse för tolkningen av resultatet av PSA-testning av män med misstänkt PCa. &lt;br/&gt;&lt;br&gt; De motsägelsefulla resultaten från studier på sambandet mellan CAG-repetitioner och manliga hormonberoende sjukdomstillstånd kan bero på den statistiska modell som används. Vi använde en modell som förutsättningslöst kan bestämma sambandet vilket är en fördel mot andra metoder då man utgår ifrån ett linjärt samband eller att man delar in männen i grupper. Analysen gjordes på över 500 svenska unga friska män med alla tre statistiska metoder och visade ett samband mellan genotypen och hormoner som styr T regleringen. Samma metoder användes för att undersöka om genotypen kan modifiera effekten av rökning på manliga reproduktionsparametrar, då rökning har visat sig minska spermiekoncentrationen och påverka andra viktiga funktioner som upprätthåller fertiliteten. Vi fann att män som rökte och hade många CAG-repetitioner hade mindre sädesvätska än rökande män med färre CAG -repetitioner, en effekt som inte fanns hos icke-rökare. Våra resultat indikerar att AR-genotypen har en betydelse för känsligheten av miljögifter på den manliga reproduktionsfunktionen.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/de0cb698-27ad-424e-8987-6009fa8b26d2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Christel_Final.pdf">https://portal.research.lu.se/files/3044061/3126406.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1269068</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>reproductive function</topic> <topic>smoking</topic> <topic>4&apos;.4-DDE</topic> <topic>persistent organic pollutants</topic> <topic>prostate cancer</topic> <topic>Androgen receptor</topic> <topic>prostate specific antigen</topic> <topic>CAG polymorphism</topic> <topic>TCDD</topic> <topic>aryl hydrocarbon receptor</topic> <topic>CB-153</topic> </subject> <subject authority="lup"> <topic>Gynaecology, Obstetrics and Reproductive Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-50-0</identifier> <identifier type="oldLupId">3126399</identifier> <part> <detail type="volume"> <number>2012:87</number> </detail> <extent unit="pages"> <total>164</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-10-26T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>de0cb698-27ad-424e-8987-6009fa8b26d2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:00+02:00</recordDateApproved> </recordInfo> </mods>

This process is referred to as semantic role labeling. This dissertation describes how to construct statistical models for semantic role labeling of English text, and how role semantics is related to surface syntax.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; It is generally agreed that the problem of semantic role labeling is closely tied to syntactic analysis. Most previous implementations of semantic role labelers have used constituents as the syntactic input, while dependency representations, in which the syntactic structure is viewed as a graph of labeled word-to-word relations, has received very little attention in comparison. Contrary to previous claims, this work demonstrates empirically that dependency representations can serve as the input for semantic role labelers and achieve similar results. This is important theoretically since it makes the syntactic-semantic interface conceptually simpler and more intuitive, but also has practical significance since there are languages for which constituent annotation is infeasible.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The dissertation devotes considerable effort to investigating the relation between syntactic representation and semantic role labeling performance. Apart from the main result that dependency-based semantic role labeling rivals its constituent-based counterpart, the empirical experiments support two findings: First, that the dependency-syntactic representation has to be well-designed in order to achieve a good performance in semantic role labeling. Secondly, that the choice of syntactic representation affects the substages of the semantic role labeling task differently; above all, the role classification task, which relies strongly on lexical features, is shown to benefit from dependency representations.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The systems presented in this work have been evaluated in two international open evaluations, in both of which they achieved the top result.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/11b39516-0de3-4a22-9150-ffa032512e89</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="johansson-dissertation.pdf">https://portal.research.lu.se/files/3045111/1262839.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1080191</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Computer Science, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Natural language processing</topic> <topic>syntax</topic> <topic>semantics</topic> <topic>computer science</topic> </subject> <subject authority="lup"> <topic>Computer Sciences</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-628-7628-9</identifier> <identifier type="oldLupId">1262838</identifier> <part> <extent unit="pages"> <total>167</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-05T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>11b39516-0de3-4a22-9150-ffa032512e89</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:02+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-27T13:34:18Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:02+02:00</recordDateApproved> </recordInfo> </mods>

To regulate the process of collagen matrix assembly, the cells secrete small leucine-rich repeat proteoglycans (SLRPs) that bind to collagen and influence its fibril formation. In this manner, fibromodulin - one of the SLRPs - can alter intermolecular cross-linking of collagen, which has long-term implications for the structural integrity of the connective tissue. Since SLRPs can bind to collagen in via different domains, and are expressed in different tissues, their regulation of collagen matrices is fine-tuned for the physiological requirements. For example, decorin and lumican interact with collagen using their central leucine-rich repeat domains, while fibromodulin makes use of its C-terminal domain. In addition, some SLRPs can inhibit each other&apos;s binding to collagen. These differences, together with the detailed knowledge on matrix protein interactions, can be useful to explain the development of connective tissues. In a longer time perspective, this knowledge could allow to manipulate fibrotic processes in pathological conditions like cancer or atherosclerosis - the two major causes of death in our society. The potential for such intervention is high, since fibromodulin is abundant in cancer stroma, raising its interstitial fluid pressure that hinders an efficient anti-cancer drug medication. Furthermore, fibromodulin is expressed in atherosclerotic plaques, regulating the growth of the fibrous cap and activity of smooth muscle cells. These observations validate further investigations into this field of connective tissue biology.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/09151c39-79dd-4dca-ac5d-72fa96bc7947</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Sebastian Kalamajski avhandling.pdf">https://portal.research.lu.se/files/167650135/Sebastian_Kalamajski_avhandling.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3016574</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-83-4</identifier> <identifier type="oldLupId">1044892</identifier> <part> <detail type="volume"> <number>2008:30</number> </detail> <extent unit="pages"> <total>166</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-04-01T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>09151c39-79dd-4dca-ac5d-72fa96bc7947</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:14+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:14+02:00</recordDateApproved> </recordInfo> </mods>

The therapy is essentially based on insulin injections and depends strongly on patient daily decisions, being mainly based upon empirical experience and rules of thumb. The development of a prediction engine capable of personalized on-the-spot decision making concerning the most adequate choice of insulin delivery, meal intake and exercise would therefore be a valuable initiative towards an improved management of the desease. &lt;br/&gt;&lt;br/&gt;This thesis presents work on data-driven glucose metabolism modeling and short-term, that is, up to 120 minutes, blood-glucose prediction in Type 1 Diabetes Mellitus (T1DM) subjects. &lt;br/&gt;&lt;br/&gt;In order to address model-based control for blood glucose regulation, low-order, individualized, data-driven, stable, physiological relevant models were identified from a population of 9 T1DM patients data. Model structures include: autoregressive moving average with exogenous inputs (ARMAX) models and state-space models.&lt;br/&gt;&lt;br/&gt;ARMAX multi-step-ahead predictors were estimated by means of least-squares estimation; next regularization of the autoregressive coefficients was introduced. ARMAX-based predictors and zero-order hold were computed to allow comparison.&lt;br/&gt;&lt;br/&gt;Finally, preliminary results on subspace-based multi-step-ahead multivariate predictors is presented.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/15437c9e-2599-424b-a09e-c26537680327</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="cescon2011lic.pdf">https://portal.research.lu.se/files/3046188/1982462.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7156778</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>system identification</topic> <topic>prediction</topic> <topic>biological systems</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Research Reports TFRT-3250</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">1982458</identifier> <part> </part> </relatedItem> <recordInfo> <recordIdentifier>15437c9e-2599-424b-a09e-c26537680327</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:17+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-19T08:54:31Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:17+02:00</recordDateApproved> </recordInfo> </mods>

We investigated processes that could contribute to the development of T2D. In addition to well-known hallmarks of the disease, such as defective insulin secretion, insulin resistance and perturbed glucagon secretion, we aimed to find a possible role for CLOCK genes in the pathogenesis of T2D. &lt;br/&gt;&lt;br&gt; In paper 1, we showed that there is a link between the expression levels of core CLOCK genes in human islets and functional parameters important for T2D. This link to T2D was particularly strong for the core CLOCK components, PER2, PER3 and CRY2. We further investigated this possibility in paper 2, where we found that silencing of Per3 in a beta cell line disrupted insulin secretion in response to glucose and other secretagogues. Our observations suggest that exocytosis may be an underlying cause. In support of this assumption, we found down-regulation of crucial genes involved in the exocytotic machinery upon silencing of Per3. Together, our observations suggest that there is a link between the circadian clock machinery and beta cell function.&lt;br/&gt;&lt;br&gt; In paper, 3 we employed an alpha and a beta cell line, which were challenged with the same stimuli. We compared their responses in hormone release and metabolism in order to understand metabolic control of glucagon secretion. We found that two cell lines responded similarly to glucose: alpha cells increased glucagon secretion upon glucose stimulation while beta cells increased secretion of insulin. Differences, however, were primarily found in the coupling of glycolytic and mitochondrial metabolism. Moreover, inhibiting the malate-aspartate shuttle completely abolished glucagon secretion, while insulin secretion was largely preserved. This was likely due to a compensatory activity in the glycerolphosphate shuttle in beta cells.&lt;br/&gt;&lt;br&gt; So far, most observations seemed to involve mitochondrial metabolism in some way. Therefore we studied how mitochondria become molecularly equipped for metabolic coupling in beta cells. Characterization of a beta cell-specific knockout of Tfb1m (beta Tfb1m-/-), which encodes a protein controlling translation of mitochondrial proteins, showed mitochondrial dysfunction. This confirmed previous findings where TFB1M was identified as T2D risk gene in human islets. Islets from β-Tfb1m-/- mice showed impaired insulin secretion, contained less insulin in secretory granules and exhibited reduced beta cell mass. Mitochondria exhibited disrupted architecture. All measured metabolic parameters in mitochondria were impaired. Reactive oxygen species were increased, and signs of apoptosis and necrosis with accompanying inflammation were observed. &lt;br/&gt;&lt;br&gt; These studies have illustrated the complexity of the mechanisms involved in the pathogenesis of T2D. Thus, investigating different metabolic aspects of its pathogenesis, supported the multifactorial nature of the underlying mechanism of T2D development.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Diabetes mellitus är en endokrin sjukdom. Hos friska individer producerar beta och alpha cellerna i bukspottkörteln insulin och glukagon, de viktigaste hormonerna för att reglera blodglukos¬koncentrationen. Insulin utsöndras som svar på förhöjda blodglukosnivåer. Hormonet minskar glukosproduktion från levern och ökar glukosupptaget samt dess användning och lagring i fett och muskler. Glukagon har motsatta effekter: det höjer glukos i blodet genom att stimulera dess produktion i lever.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Diabetes mellitus är heterogen sjukdom. Den åtföljs av ett stort antal komplikationer i det sena skedet. Det tydligaste tecknet på sjukdomen är förhöjd blodglukosnivå. När sjukdomen förekommer hos barn och ungdomar, som en följd av absolut insulinbrist på grund av autoimmun destruktion av beta celler, talar vi om typ 1-diabetes (T1D). Patienter med T1D kräver livslång behandling med insulin. Om sjukdomen förekommer hos vuxna på grund av otillräcklig insulinfrisättning och insulinresistens benämns den typ 2-diabetes (T2D). Förekomsten av T2D ökar stadigt – vi säger att en diabetespandemi utbreder sig på kontinenterna. Sjukdomsutvecklingen, dvs. patogenes, är komplicerad och inte fullt klarlagd, eftersom många faktorer bidrar till dess utveckling. Livsstil med övervikt och fysisk inaktivitet samt en stark genetisk komponent är välkända faktorer förknippade med T2D.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi studerade olika processer som kan vara bakomliggande mekanismer för utveckling av T2D. Ett föremål för våra undersökningar var dygnsrytm. Vi försökte att hitta en möjlig roll för gener som styr cellens ”klocka” vid insulinsekretion och beta cellsfunktion. Vi fann att uttryck av gener som PER2, PER3 och CRY2 minskade i humana Langerhanska öar från T2D donatorer. Deras nivåer korrelerade med metabola parametrar som är viktiga för T2D patogenes, t.ex. långtidsblodglukos (HbA1c). En minskning av Per3-gennivåer i odlade β-celler hämmade insulinsekretion.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Störd glukagonutsöndring är också en del av patogenesen vid T2D. En balanserad frisättning av insulin och glukagon är avgörande för att upprätthålla stabila blodglukosnivåer. Tyvärr saknas fortfarande en etablerad mekanism för glukagonutsöndringen. Därför har vi försökt att lösa åtminstone en del av problemet. Vi tittade på metabola svar från en odlad alpha cellinje. Vi bekräftade tidigare fynd att alpha-celler frisätter glukagon vid förhöjda glukoskoncentrationer – detta liknar svaret från beta-cellerna för frisättning av insulin. Vi fann i egentlig mening att de två cellinjerna betedde sig ganska lika även om en svagare mitokondriell aktivitet sågs i alpha-cellerna.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Slutligen, mitokondrier var ett genomgående tema i våra studier. Därför undersökte vi i vår sista studie mitokondriens roll i patogenesen av T2D, och särskilt då betydelsen av TFB1M. Detta protein styr kodning av mitokondriella andningsproteiner. Vi utförda våra studier i en mus som sakande genen för Tfb1m i insulin-producerande celler, en s.k. knock out-mus. Våra experiment in vivo och in vitro visade att förlusten av Tfb1m i β-celler ledde till mitokondriell dysfunktion och därmed nedsatt insulinsekretion; tillsammans med en minskning av beta-cellmassa bidrog detta till T2D utveckling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Våra studier har belyst komplexiteten av orsakerna till T2D, en av vår tids stora folksjukdomar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d39f6051-cf5b-42d4-8bc2-d94fac04b724</url> </location> </relatedItem> <originInfo> <publisher>Molecular Metabolism</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>CLOCK genes</topic> <topic>insulin</topic> <topic>glucagon</topic> <topic>metabolites</topic> <topic>mitochondria</topic> <topic>knock out</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-008-1</identifier> <identifier type="oldLupId">4446883</identifier> <part> <detail type="volume"> <number>2014:79</number> </detail> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-13T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>d39f6051-cf5b-42d4-8bc2-d94fac04b724</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-12-08T10:59:06Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:19+02:00</recordDateApproved> </recordInfo> </mods>

CT spine according to protocols available in daily clinical practice means high radiation dose to these young individuals. All examinations included in this thesis were performed on a 16-slice CT scanner. Examination of the chest phantom in paper I showed that the radiation dose of the spine (including 15 vertebrae) was 20 times lower than that of routinely used protocols for CT examination of the spine in children (0.38 mSv vs 7.76 mSv). In paper II the radiation dose and the impact of dose reduction on image quality were evaluated in 113 consecutive examinations with low-dose spine CT and compared with that of 127 CTs after trauma and 15 CTs performed according to a previously used ANV-protocol of a limited part of the vertebral column. The effective dose of the low-dose spine CT (0.01 mSv/cm scan length) was 20 times lower than that of the standard CT for trauma (0.20 mSv/cm scan length). The absorbed doses to the breasts, genital organs, and thyroid gland in the low-dose spine CT was 8, 265, and 22 times lower than the corresponding doses in CT for trauma. This significant dose reduction conveyed no impact on image quality with regard to answering the clinical questions at issue for the preoperative CTs and for the postoperative CTs after posterior corrective surgery. In paper III the low-dose CT showed to be a reliable method in the evaluation of screw placement in patients with AIS after posterior scoliosis surgery with titanium implants, using the new grading system for screw misplacement. Our proposed grading system for screw misplacement has shown to be feasible, practical, and easy to perform and is in line with the general agreement about the harmlessness of misplacement with minor pedicle breach. In paper IV the evaluation of the clinical and radiological outcome of 49 patients with AIS operated on with titanium “all-pedicle screw construct” showed an overall misplacement rate of 17 %. No evidence of neurovascular complications was reported. In parity with most of the reports in the literature the lateral- and medial cortical perforation were the most common types of screw misplacement (8 % and 6.1 % respectively).</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/fc500a4c-146b-4ab3-b038-1d1c2f2a866d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kasim_hela_g5.pdf">https://portal.research.lu.se/files/3049478/1370311.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8174289</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Radiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>low-dose spine CT</topic> <topic>effective dose</topic> <topic>screw misplacement</topic> <topic>adolescent idiopathic scoliosis</topic> <topic>outcome.</topic> <topic>titanium screws</topic> <topic>image quality</topic> <topic>neurovascular complication</topic> <topic>phantom</topic> </subject> <subject authority="lup"> <topic>Radiology and Medical Imaging</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-29-5</identifier> <identifier type="oldLupId">1369005</identifier> <part> <detail type="volume"> <number>2009:42</number> </detail> <extent unit="pages"> <total>158</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-12T09:15:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

During this period, testicular cancer has increased several-fold. Environmental and lifestyle-related factors have been proposed as explanations for a possible negative trend in male reproductive function. One important lifestyle factor is smoking. However, smoking during pregnancy appears to play a greater role for a man&apos;s reproductive function than smoking by the man himself. As regards environmental chemicals, one type of compound to which humans are exposed is phthalates. These are often used as plasticizers in different consumer products. Several phthalates have been reported as decreasing male reproductive function in laboratory animals, especially when given during the foetal period.&lt;br/&gt;&lt;br&gt; Between 2008 and 2010, 314 men from the general Swedish population were recruited. Their semen quality was compared with a group of men recruited in a similar manner between 2000 and 2001. &lt;br/&gt;&lt;br&gt; The participants also delivered serum and urinary samples and answered questionnaires concerning maternal and paternal smoking during pregnancy. Data on maternal smoking was additionally assessed through the Swedish Medical Birth Register. Through a Swedish screening program for rubella, maternal serum samples were retrieved from the men&apos;s prenatal period. We analysed metabolites of phthalates as exposure markers both in the maternal sera and in urine and serum of the men. Associations between parental smoking during pregnancy as well as phthalate metabolite levels, and parameters of male reproductive function were studied.&lt;br/&gt;&lt;br&gt; In summary, we found no change in semen quality between 2000-2001 and 2008-2010. However, both maternal and paternal smoking during pregnancy were associated with reduced sperm counts in men whose other parent did not smoke. In addition, prenatal exposure to diethylhexyl phthalate (DEHP) and diisononyl phthalate (DiNP) appeared to be associated with decreased semen volume, and exposure to DiNP as well with smaller testicular size. Finally, adult exposure to DEHP and dibutyl phthalate (DBP) were associated with decreased progressive sperm motility, and DEHP exposure was also linked to a higher proportion of immature sperm. &lt;br/&gt;&lt;br&gt; Thus, although no change in semen quality appeared to have occurred in Swedish men during the last decade, parental smoking and prenatal and adult exposure to certain phthalates may play a role in the male reproductive function.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Det har diskuterats huruvida mäns spermiekoncentration minskat och missbildningar i pojkars könsorgan ökat under den senare delen av 1900-talet. Med säkerhet har dock testikelcancer ökat flerfaldigt under samma tidsperiod.&lt;br/&gt;&lt;br&gt; Målet med denna avhandling var dels att undersöka huruvida skånska mäns spermakvalitet hade förändrats under det förra årtiondet, dels att studera samband mellan olika miljöfaktorer och manlig reproduktionsfunktion. Dessa miljöfaktorer var exponering för egen rökning, föräldrarnas rökning under graviditeten, samt för ftalater (en sorts plastmjukgörare) både under fostertiden och i vuxenlivet. &lt;br/&gt;&lt;br&gt; Vi rekryterade 314 unga män mellan år 2008 och 2010, främst från Pliktverket i Kristianstad i samband med mönstringen, och i viss utsträckning också män från gymnasieskolor i Malmö-Lund-området. Männen fick besvara frågor om föräldrarnas rökning under graviditeten. Uppgifter om moderns rökning inhämtades även från Socialstyrelsens födelseregister. &lt;br/&gt;&lt;br&gt; Vi hade tillgång till blodprov från 112 av männens mödrar, tagna under graviditeten. Dessa prov hade tagits vid en screening för röda hund, varefter proven sparats i en biobank. I dessa prov, liksom i urin- och blodprov från männen själva, mättes nedbrytningsprodukter (metaboliter) av ftalater som markörer för exponering. &lt;br/&gt;&lt;br&gt; De rekryterade männens spermakvalitet jämfördes med den hos män rekryterade på ett liknande sätt år 2000 till 2001. Därefter studerades samband mellan exponering för både rökning och ftalater såväl under fostertiden som i vuxenlivet, och männens reproduktionsfunktion.&lt;br/&gt;&lt;br&gt; Vi fann inte någon förändring i spermakvaliteten under det senaste årtiondet. &lt;br/&gt;&lt;br&gt; Däremot hade de män vars fäder eller mödrar rökt under graviditeten ett påtagligt lägre spermieantal. Vidare tycktes exponering under fostertiden för de två ftalaterna di-isononylftalat (DiNP) och dietylhexylftalat (DEHP) ha samband med en sänkt testikelvolym respektive spermavolym. Slutligen hade exponering för DEHP och dibutylftalat (DBP) i vuxenlivet samband med en lägre andel framåtrörliga spermier, vilket kan tänkas påverka fertiliteten. &lt;br/&gt;&lt;br&gt; Således verkade både exponering föräldrarnas rökning under graviditeten och för ftalater under fostertiden samt i vuxenlivet, ha samband med en sänkt manlig reproduktionsfunktion.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8d0ce4e8-c937-41cd-932e-e0432d3afedb</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_sprAY_kgranskad_final.pdf">https://portal.research.lu.se/files/3049867/5337406.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">11793291</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Molecular Reproductive Medicine</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Semen analysis</topic> <topic>maternal exposure</topic> <topic>paternal exposure</topic> <topic>smoking</topic> <topic>phthalate</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> <topic>Gynaecology, Obstetrics and Reproductive Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-124-8</identifier> <identifier type="oldLupId">5337327</identifier> <part> <detail type="volume"> <number>2015:45</number> </detail> <extent unit="pages"> <total>75</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-22T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>8d0ce4e8-c937-41cd-932e-e0432d3afedb</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:24+02:00</recordDateApproved> </recordInfo> </mods>

The puzzle underlying this dissertation is therefore to probe what constitutes a just peace, both conceptually within the field of peacebuilding and empirically in the context of the EU as a peacebuilder in the Israeli-Palestinian conflict. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The EU has used the term just peace in many of its most important declarations on the Israeli-Palestinian conflict throughout the years. Defining a just peace is about these declaratory efforts by the EU to articulate a common formula of a just peace in the conflict. Securing and building a just peace are about the EU’s role in implementing this formula for a just peace in the conflict through the creation of a Palestinian state. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; As the EU enters its fifth decade of involvement in the conflict, there can be little doubt that in common with the rest of the international community it has failed in its efforts to establish a just peace between Israelis and Palestinians. While this is an inescapable overall conclusion from four decades of EC/EU peacebuilding in the conflict, it is, at the same time, possible to draw a number of other conclusions from this study. Most importantly, it will be argued that the EU is a major legitimizing power in the conflict and that it has kept the prospects of a two-state solution alive through its support for the Palestinian statebuilding process.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Det talas mycket om rättvis fred i den allmänna debatten men det är ett ämne som är lite utforskat av akademiker. Det vetenskapliga pusslet som ligger till grund för denna avhandling är att undersöka vad en rättvis fred är, dels konceptuellt i fredsbyggande mer generellt, och empiriskt i förhållande till EU och den israelisk-palestinska konflikten. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; EU har använt termen rättvis fred i många av sina uttalanden om den israelisk-palestinska konflikten under årens lopp. Defining en rättvis fred handlar om dessa uttalanden. Securing och building en rättvis fred handlar om EU:s roll i att implementera sin vision om en rättvis fred i konflikten genom skapandet av en palestinsk stat vid sidan av Israel.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; När EU nu går in i sitt femte årtionde av att försöka etablera en rättvis fred mellan parterna står det klart att EU tillsammans med övriga delar av det internationella samfundet misslyckats med att etablera en rättvis fred mellan israeler och palestinier. Fastän detta är en övergripande slutsats av fyra årtiondens fredsbyggande av EU i konflikten står det samtidigt klart att Unionen gjort betydande insatser för fred i konflikten. I avhandlingens slutkapitel argumenterar jag för att EU är en viktig legitimerande makt i konflikten samt att Unionen hållit möjligheterna för förverkligandet av en palestinsk stat vid liv genom sitt fredsbyggande.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/cc01d1d5-0560-45e3-ba67-74b7f8306f74</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Anders_avh_E5_media.pdf">https://portal.research.lu.se/files/3049963/3736685.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3059548</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Isareli-Palestinian conflict</topic> <topic>peace</topic> <topic>EU</topic> <topic>peace building</topic> <topic>Just peace</topic> <topic>Middle East peace process</topic> <topic>Legitimizing power Europe</topic> </subject> <subject authority="lup"> <topic>Political Science</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Political Studies</title> </titleInfo> <identifier type="issn">0460-0037</identifier> <identifier type="isbn">978-91-7473-574-1</identifier> <identifier type="oldLupId">3736680</identifier> <part> <detail type="issue"> <number>170</number> </detail> <extent unit="pages"> <total>282</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-05-31T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>cc01d1d5-0560-45e3-ba67-74b7f8306f74</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:25+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-26T12:55:12Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:25+02:00</recordDateApproved> </recordInfo> </mods>

If this response time is too long, the user&lt;br/&gt;&lt;br&gt; is likely to abandon the web site and search for other providers of&lt;br/&gt;&lt;br&gt; the service. To avoid this loss of users, it is important for the web&lt;br/&gt;&lt;br&gt; site operator to assure that users are treated sufficiently fast. On&lt;br/&gt;&lt;br&gt; the other hand, it is also important to minimize the effort to&lt;br/&gt;&lt;br&gt; optimize profit. As these objectives often are contradictory, an&lt;br/&gt;&lt;br&gt; acceptable target response-time that can be formulated. The resources&lt;br/&gt;&lt;br&gt; are allocated in a manner that ensures that long response times&lt;br/&gt;&lt;br&gt; do not occur, while, at the same time, using as little resources as&lt;br/&gt;&lt;br&gt; possible to not overprovision.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The work presented in this doctoral thesis takes a&lt;br/&gt;&lt;br&gt; control-theoretic perspective to solve this problem. The resources&lt;br/&gt;&lt;br&gt; are considered as the control input, and the response time as the main&lt;br/&gt;&lt;br&gt; output. Several disturbances affect the system, such as the arrival&lt;br/&gt;&lt;br&gt; rate of requests to the web site. A testbed was designed to&lt;br/&gt;&lt;br&gt; allow repeatable experiments with different controller&lt;br/&gt;&lt;br&gt; implementations. A server was instrumented with sensors and actuators&lt;br/&gt;&lt;br&gt; to handle requests from 12 client computers with capability for&lt;br/&gt;&lt;br&gt; changing work loads.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; On the theoretical side, a model of a web server is presented in this&lt;br/&gt;&lt;br&gt; thesis. It explicitly models a specific sensor implementation where&lt;br/&gt;&lt;br&gt; buffering occurs in the computer prior to the sensor. As a result, the&lt;br/&gt;&lt;br&gt; measurement of the arrival rate becomes state dependent under high&lt;br/&gt;&lt;br&gt; load. This property turns out to have some undesirable effects on the&lt;br/&gt;&lt;br&gt; controlled system. The model was capable of predicting the behavior of&lt;br/&gt;&lt;br&gt; the testbed quite well.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Based on the presented model, analysis shows that &lt;br/&gt;&lt;br&gt; feed-forward controllers suggested in the literature can lead to&lt;br/&gt;&lt;br&gt; instability under certain circumstances at high load. This has not&lt;br/&gt;&lt;br&gt; been reported earlier, but is in this doctoral thesis&lt;br/&gt;&lt;br&gt; demonstrated by both simulations and experiments. The analysis&lt;br/&gt;&lt;br&gt; explains why and when the instability arises.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the attempt to predict future response-times this thesis also&lt;br/&gt;&lt;br&gt; presents a feedback based prediction scheme. Comparisons between&lt;br/&gt;&lt;br&gt; earlier predictions to the real response-times are used to correct a&lt;br/&gt;&lt;br&gt; model based response time prediction. The prediction scheme is&lt;br/&gt;&lt;br&gt; applied to a controller to compensate for disturbances before the&lt;br/&gt;&lt;br&gt; effect propagates to the response time. The method improves the&lt;br/&gt;&lt;br&gt; transient response in the case of sudden changes in the arrival&lt;br/&gt;&lt;br&gt; rate of requests.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This doctoral thesis also presents work on a control solution&lt;br/&gt;&lt;br&gt; for reserving CPU capacity for a given process or a given group of&lt;br/&gt;&lt;br&gt; processes on a computer system. The method uses only existing&lt;br/&gt;&lt;br&gt; operating-system infrastructure, and achieves the desired&lt;br/&gt;&lt;br&gt; CPU capacity in a soft real-time manner.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e81378aa-35b0-472f-ac91-cbd87234e0ce</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="MartinAnsbjergKjaer_Reglerteknik_Avhandling.pdf">https://portal.research.lu.se/files/3050790/1488249.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3145844</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>feed-forward</topic> <topic>dynamic prediction</topic> <topic>computer systems</topic> <topic>queuing theory</topic> <topic>Web server</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>PhD Thesis TFRT-1086</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">1488247</identifier> <part> <extent unit="pages"> <total>178</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-11-20T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>e81378aa-35b0-472f-ac91-cbd87234e0ce</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:32+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:32+02:00</recordDateApproved> </recordInfo> </mods>

The intestinal immune system has the important task of protecting us against infection while maintaining tolerance against the vast amount of commensal microbes populating the intestinal tract and the multitude of foreign antigen present in the diet. Intestinal dendritic cells (DCs) have a central role in maintaining homeostasis and their continual migration from the intestinal mucosa to the draining mesenteric lymph nodes (MLN) is required for the induction of adaptive immune responses to orally derived antigen as well as the development of oral tolerance to food proteins. Migratory DCs are also thought to have a central role in the induction of gut-homing receptors on T cells, allowing the T cells to home to the gut and perform effector functions.&lt;br/&gt;&lt;br&gt; In this thesis I investigate the signals that drive DC migration to the MLN under homeostatic and inflammatory conditions. The results presented show that in the steady state, DC migration is driven by the adaptor protein MyD88, which mediates signaling through pattern recognition receptors of the Toll-like receptor family as well as receptors of the cytokines IL-1β, IL-18 and IL-33. While optimal DC migration requires MyD88 signaling in CD11c+ cells, including DCs, it is independent of the microbiota, caspase-1-induced maturation of IL-1β and IL-18 and signaling through the IL-18 receptor. Additionally, we find that DC migration in response to an inflammatory stimulus requires TNF-α signaling, in contrast to the steady state migration that is TNF-α independent. We further find that induction of the gut-homing receptor CCR9 on T cells in an inflammatory setting requires TNF-α signaling in stromal cells, but is independent of TNF-α-induced DC migration from the intestine. As TNF-α is involved in the pathology of inflammatory bowel disease (IBD), and TNF-α-neutralizing therapies are used in IBD with great success, these findings could aid the understanding of the mechanisms involved in intestinal inflammation and anti-TNF therapy efficacy.&lt;br/&gt;&lt;br&gt; Although IL-18 signaling did not drive steady state DC migration, we found that it had a role in the generation of IFN-γ producing T cells and in cytokine-induced TCR-independent innate-like cytokine production by T cells in a T cell-dependent mouse model of intestinal inflammation. Impaired IL-18 signaling in the T cells did however not have an impact on disease severity. This data could also aid the understanding of disease mechanisms in IBD.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/28992de5-6a39-42b8-b7a1-be0bb6331ee1</url> </location> </relatedItem> <originInfo> <publisher>Section for Immunology, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Immunology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-190-3</identifier> <identifier type="oldLupId">8051569</identifier> <part> <detail type="volume"> <number>2015:111</number> </detail> <extent unit="pages"> <total>84</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-10-30T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>28992de5-6a39-42b8-b7a1-be0bb6331ee1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:55+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:55+02:00</recordDateApproved> </recordInfo> </mods>

In this thesis a purely image based approach is proposed to solve this problem. In order to create a complete image based system, there are many subproblems that have to be addressed. The localization problem can also be solved in other ways, for example, with a GPS. Two advantages with using images compared to GPS are that no open sky is needed and that a higher precision is possible to achieve. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The thesis consists of an introductory chapter followed by six papers. In the first paper, enhancements of Gröbner basis techniques to solve systems of polynomial equations are presented. The new strategies improve the numeric stability with several orders of magnitudes, compared to previous state of the art. This framework is then applied in the next three papers to solve several geometrical pose problems relevant for localization. The main difference between the papers is the level of knowledge of the inner calibration of the cameras. The calibration knowledge ranges from completely calibrated cameras to uncalibrated cameras with unknown radial distortion. The fifth paper of the thesis also treats the pose problem, but the method differs from the previous papers. In this paper a method is presented that guarantees a globally optimal solution at the price of computational complexity. To achieve this, the pose problem is reformulated and solved via a minimal vertex cover. The final paper is devoted to large-scale localization. Methods from image retrieval are utilized, and extended, to be able to perform city-scale localization. Moreover geometry is directly incorporated in the retrieval stage.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Var är bilden tagen? Det är en fråga som vi ofta ställer oss och som denna avhandling innehåller matematiska metoder för att låta en dator besvara. Om vi lyckas svara på frågan kan metoderna för att hitta svaret användas till vitt skilda saker. Det går att använda för att låta robotar navigera med hjälp av kameror men också för att sortera privata bilder i digitala fotoalbum efter var de är tagna.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att lösa lokaliseringsproblemet har flera delproblem studerats. I ett av delproblemen har en tredimensionell modell av Malmö byggts upp utifrån 95~000 bilder tagna utmed stadens gator. Med hjälp av modellen går det för en ny bild, tagen någonstans i Malmö att avgöra var fotografen befann sig. Det görs genom att titta på många små områden i den nya bilden. De områdena beskrivs sedan med en uppsättning tal så att liknande områden går att hitta i den tredimensionella modellen. Om tillräckligt mycket är känt om kameran som tagit bilden går det att räkna ut vilken vinkel det är mellan riktningarna till två punkter som avbildats i bilden, sett från kameran. Tack vare den tredimensionella modellen av staden är det sedan möjligt att räkna ut var i Malmö den vinkeln kan uppstå mellan punkterna. Med hjälp av det går det att få fram en lista på platser där bilden kan vara tagen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det som hittills har beskrivits kan fungera som ett första steg i en lokaliseringsprocess. För att ta reda på mera om kamerans position, så som riktning, eller för att få en högre precision i resultatet kan man utgå från resultatet av den första delen för att hitta positioner att undersöka noggrannare. Även de fortsatta algoritmerna för att söka efter position har utvecklats i avhandlingen. När antalet tänkbara platser begränsats efter det första steget är det möjligt att utföra mera resurskrävande beräkningar som en dator inte skulle klara av för en hel stad på rimlig tid. I arbetet har det utvecklats två typer av algoritmer för detta problem, dels en som är optimal, alltså att det är säkert att det inte finns en bättre lösning, dels metoder som går snabbare men som inte garanterat ger ett optimalt resultat.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det kan låta konstigt att inte nöja sig med en metod som ger ett optimalt svar, men dessa algoritmer tar ofta för lång tid att använda, och då får vi hoppas på att kunna ta en genväg för att hitta en nästan lika bra lösning. Det visar sig också att det i de flesta fallen blir fullt tillfredsställande lösningar även när den snabba vägen används.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det arbete som gjorts på de snabbare metoderna i avhandlingen handlar till stor del om beräkningar kopplade till hur kameror avbildar omgivningen. För olika matematiska modeller av en kamera, som är beroende av hur mycket som är känt om kamerans konstruktion och även vilken brännvidd som användes vid fototillfället, blir det olika geometriska problem att lösa. Vid användning av de snabba algoritmerna utnyttjas ett minimalt antal punkter i bilden, som har kopplats samman med punkter i den tredimensionella modellen, för att problemet ska kunna lösas. Sedan löses problemet för denna minimala uppsättning punkter. Lösningen testas hur väl den stämmer överens med de övriga punkterna som kopplats samman mellan bilden och modellen. Många tidigare olösta sådana problem, där ett minimalt antal punkter är kopplade mellan kameran och modellen, presenteras det lösningar på i avhandlingen. Lösningarna blir då en viktig kugge i ett fullständigt lokaliseringssystem.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/cf04de44-7590-4c5c-a9e2-be439a1a0f02</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="final.pdf">https://portal.research.lu.se/files/3053172/1585796.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4851652</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Centre for Mathematical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Multiple View Geometry</topic> <topic>Image Based Localization</topic> <topic>Computer Vision</topic> <topic>Gröbner Basis</topic> <topic>Minimal Problems</topic> </subject> <subject authority="lup"> <topic>Mathematical Sciences</topic> <topic>Computer graphics and computer vision</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-628-8062-0</identifier> <identifier type="oldLupId">1585793</identifier> <identifier type="other">LUTFMA-1040-2010</identifier> <part> <extent unit="pages"> <total>216</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-12T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>cf04de44-7590-4c5c-a9e2-be439a1a0f02</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:55:57+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-13T09:49:20Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:55:57+02:00</recordDateApproved> </recordInfo> </mods>

It does not show any symptoms in its early stages, hence most (&amp;gt;85%) of the patients are diagnosed at late stage. At the time of diagnosis, metastases are frequently observed which make most patients unsuitable for curative surgical treatment and chemotherapy remains the only choice for them. In addition, PC is resistant to chemotherapy and currently available treatments provide only marginal survival benefits. PC is characterized by a dense desmoplastic (stromal) reaction surrounding the tumour cells, which is believed to promote tumour survival and chemoresistance. Although being a central pathological feature of pancreatic cancer, the cellular and molecular interactions underlying the stromal reaction remain incompletely understood.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The aim of the thesis was to investigate the role of the tumour microenvironment in pancreatic cancer progression.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To address the role of the stroma, we have managed to generate the first conditionally immortalized human nontumour (NPSC) and tumour-derived pancreatic stellate cells (TPSC). PSCs are believed to be the principal source of the stromal reaction in PC. In our study, we have found that insulin-like growth factor-I stimulated the proliferation of both PSCs. Both basal and IGF-I stimulated motility was significantly enhanced in TPSC compared to NPSC. Further we have found that curcumin and L49H37 effectively inhibited proliferation and&lt;br/&gt;&lt;br&gt; induced apoptosis in TPSC. TPSC were retained in the G0/G1 phase of the cell cycle through the down-regulation of p21WAF1/Cip1. L49H37 significantly decreased the phosphorylation of ERK1/2. L49H37 was found to be more potent at a lower concentration than curcumin.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; It has been stated that secreted protein acidic and rich in cysteine (SPARC) is involved in the tumour-stroma interaction. We have evaluated SPARC expression in normal pancreas, invasive adenocarcinoma and lymph node metastasis. Our data revealed that SPARC expression was absent in normal pancreas but expressed in invasive adenocarcinoma and its expression was maintained in subsequent metastases. SPARC expression was exclusively found in stromal cells. The survival of patients with high stromal SPARC expression was significantly worse than that of the patients with low stromal SPARC expression (11.5 vs 25.3 months; p = 0.020).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We observed that combined treatment of sorafenib and celecoxib synergistically induced growth inhibition and apoptosis in pancreatic cancer cells (PCC) through a process involving p21WAF1/Cip1 suppression.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis provides insights into interactions and mechanisms within the pancreatic tumour microenvironment, with potential implications for targeted interventions.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Pankreascancer (cancer i bukspottkörteln) utgör fjärde orsak död i cancer. Det är den cancerform som har den dystraste prognosen av alla, med en 5-års överlevnad mindre än 6%. Sjukdomsrelaterade symptom uppträder ofta sent i förloppet och det saknas metoder för tidig diagnos varför de flesta av patienterna upptäckts i sent skede. Endast cirka 20 procent av patienterna kan bli föremål för kurativt syftande kirurgi men av dessa kommer flertalet få återfall i sin sjukdom. För de allra flesta patienterna är onkologisk behandling aktuell, antingen som tilläggsbehandling efter kirurgi eller i palliativt syfte. Cellgiftsbehandling har visats ge överlevnadsvinster&lt;br/&gt;&lt;br&gt; men nyttan är endast marginell och endast en liten andel av patienterna svarar på given cellgiftsbehandling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Pankreascancer kännetecknas av en uttalad bindvävsreaktion (stroma) som omger och infiltrerar tumörcellerna. Stromat bidrar till att skapa en tumörmikromiljö som är gynnsam för tumören genom att bidra till tumörtillväxt och cellgiftsresistens. Trots att stromat har en central betydelse vid pankreascancer, är de cellulära och molekylära faktorerna som bidrar till stromareaktionen ofullständigt kartlagda.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Syftet med denna avhandling var att undersöka vilken roll tumörmikromiljön har vid pankreascancer med målsättning att nå ökad förståelse om faktorer som bidrar till cancertillväxt och möjligheter att utveckla riktad behandling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete I har vi för första gången lyckats skapa två immortaliserade humana cellinjer bestående av normala respektive tumör-associerade pankreatiska stellatceller. De pankreatiska stellatcellerna anses ha en nyckelroll i den stromala reaktionen vid pankreascancer. I denna studie fann vi att IGF-I stimulerade tillväxten av båda cellinjerna. Den cellulära motiliteten var ökad i de tumörassocierade stellatcellerna jämfört med de normala cellerna och stimulerades ytterligare av IGF-I.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete II fann vi att gurkmeja och L49H37 (en ny gurkmeja analog) hämmade tillväxten av tumör-associerade pankreatiska stellatceller och bidrog till ökade nivåer av apoptos (programmerad celldöd). De tumör-associerade pankreatiska stellatcellerna stannade i G0/G1-fasen av cellcykeln genom nedreglering av p21WAF1/Cip1. L49H37 minskade signifikant fosforyleringen av ERK1/2. Vidare fann vi att det krävdes endast en tiondel av dosen L49H37 jämfört med vanlig gurkmeja för att uppnå samma tillväxthämmande effekt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete III studerades proteinet SPARC som anses vara involverad i tumörstroma interaktionen vid pankreascancer. Vi analyserade uttrycket av SPARC i normal pankreas, primär pankreascancer samt lymfkörtelmetastaser. Våra resultat visade att SPARC uttryck saknades i normal pankreas men att proteinet var uttryckt i pankreascancer och detta uttryck behölls i metastaserna. SPARC uttryck begränsades till de stromala cellerna. Överlevnaden av patienter med högt stromalt SPARC uttryck var betydligt sämre än för de patienter med lågt stromal SPARC uttryck (11,5 vs 25,3 månader, p = 0,020).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete IV fann vi att kombinerad behandling av sorafenib och celecoxib synergistiskt inducerade tillväxthämning och apoptos i pankreascancerceller genom en process som involverar nedreglering av p21WAF1/Cip1.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8f4bdca8-b3a6-473f-9095-adbc6232c22e</url> </location> </relatedItem> <originInfo> <publisher>Surgery (Lund)</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-145-3</identifier> <identifier type="oldLupId">5337109</identifier> <part> <detail type="volume"> <number>2015:66</number> </detail> <extent unit="pages"> <total>56</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-25T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>8f4bdca8-b3a6-473f-9095-adbc6232c22e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:56:04+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:56:04+02:00</recordDateApproved> </recordInfo> </mods>

During revascularization, microemboli may complicate treatment and affect cardiac function. The long-term effects of microembolization are not fully elucidated.&lt;br/&gt;&lt;br&gt; Following an MI it is important to accurately determine the size of the infarction, as it can be used for guidance in terms of prognosis. However, in the acute setting after an MI the infarct size may be overestimated due to the inclusion of a possible reversibly injured area around the infarction, the peri-infarction zone.&lt;br/&gt;&lt;br&gt; In chronic MI and in non-ischemic cardiomyopathies, heterogeneous fibrotic areas have been proposed as substrate for arrhythmias which may cause sudden cardiac death (SCD). Quantification of these areas may provide better risk stratification than current guidelines.&lt;br/&gt;&lt;br&gt; In young people and athletes the most common cause for SCD is hypertrophic cardiomyopathy (HCM), possibly due to areas of fibrosis causing fatal arrhythmias. However, the pathophysiological mechanism behind the development of fibrosis in HCM is still unclear. Magnetic resonance imaging (MRI) can be used to assess function, perfusion and viability using late gadolinium enhancement (LGE). Therefore, this thesis investigates how MRI can be used for diagnosis, prognosis and for understanding the pathophysiological mechanisms behind ischemic and non-ischemic cardiomyopathy.&lt;br/&gt;&lt;br&gt; Study I showed that coronary microembolization causes long-term, regional left ventricular dysfunction and that even small microemboli, which may escape the distal protective devices, influence cardiac function.&lt;br/&gt;&lt;br&gt; Study II demonstrated that infarct quantification with a 2D-PSIR and a 3D-IR sequence shows good agreement in patients, which allows for the sequences to be used interchangeably. Both these LGE-sequences optimized for in vivo-use yield an overestimation of infarct size ex vivo.&lt;br/&gt;&lt;br&gt; Study III is an experimental study which showed that contrast-enhanced MRI overestimates myocardial infarct size compared to histopathology in the acute phase but not at seven days. This is associated with a significantly higher extracellular volume in the peri-infarction zone acutely compared to seven days later, possibly due to edema.&lt;br/&gt;&lt;br&gt; Study IV showed that young patients with HCM had decreased perfusion in areas with hypertrophy and even lower perfusion in LGE positive, fibrotic myocardium. The stress-induced hypoperfused regions exceed regions with fibrosis indicating that hypoperfusion precede fibrosis and may be a more sensitive marker of diseased myocardium.&lt;br/&gt;&lt;br&gt; Finally, Study V demonstrated that a heterogeneous LGE borderzone, quantified by two different algorithms, predicts appropriate ICD-therapy to a larger extent than ejection fraction, total, and core LGE size.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; När det blir stopp i ett av hjärtats kranskärl blockeras blodflödet till hjärtat, vilket kan orsaka blodbrist i en del av hjärtmuskeln. Detta kan i sin tur leda till hjärtinfarkt, vilket tar död på hjärtmuskelceller och skadar hjärtat. Vid den efterföljande behandlingen av hjärtinfarkt kan små proppar i kranskärlen, så kallade mikroembolier, ytterligare förvärra skadan på hjärtat och påverka hjärtfunktionen negativt.&lt;br/&gt;&lt;br&gt; Efter en infarkt är det av stor betydelse att bestämma infarktens storlek på ett korrekt sätt, eftersom det är vägledande för frågor rörande patientens livskvalitet och livslängd. Ett område runt själva infarkten, den så kallade peri-infarkt zonen, kan dock göra det svårt att bestämma hjärtinfarktens storlek i det akuta skedet efter infarkten. Peri-infarkt zonen kan nämligen leda till att infarktens storlek och således skadan på hjärtat överskattas.&lt;br/&gt;&lt;br&gt; Hjärtinfarkt drabbar oftast äldre människor men även unga människor kan drabbas av hjärtsjukdomar. Den vanligast hjärtsjukdomen bland barn och unga vuxna är onormal tillväxt av hjärtmuskeln, så kallad hypertrof kardiomyopati (HCM). &lt;br/&gt;&lt;br&gt; HCM kan innebära att hjärtat inte pumpar ut blod effektivt nog eller att det bildas ärr i hjärtmuskeln, vilket i sin tur kan leda till plötslig hjärtdöd. Orsaken till sådan ärrvävnad i hjärtat är ännu inte helt klarlagd. Att förstå uppkomsten av ärrvävnad i hjärtmuskeln är dock viktigt för att eventuell förebyggande behandling ska kunna ges i tid.&lt;br/&gt;&lt;br&gt; Kontrastförstärkt magnetresonanstomografi (MR) kan användas för att avbilda hjärtat i detalj och gör det därmed möjligt att undersöka ärrvävnad i hjärtat.&lt;br/&gt;&lt;br&gt; En hjärtinfarkt läker så småningom ut och skadan ombildas då till ett ärr, vilket kan orsaka oregelbunden hjärtrytm, så kallade arytmier, hos patienten. Arytmier är livshotande då det kan leda till plötslig hjärtdöd. Det finns dock förebyggande behandling att ge patienter som riskerar att drabbas av arytmier, i form av en implanterbar defibrillator (ICD). Kriterierna för vilka patienter som ska få en ICD är dock inte optimala och många patienter får en ICD inopererad utan att ha nytta av&lt;br/&gt;&lt;br&gt; den. Med en bättre förståelse för vem som faktiskt skulle ha nytta av en ICD skulle onödigt lidande och komplikationer kunna undvikas i större utsträckning än idag.&lt;br/&gt;&lt;br&gt; Syftet med denna avhandling var att se hur MR kan användas för diagnostik,&lt;br/&gt;&lt;br&gt; studera sjukdomsförlopp och för att förutsäga sjukdomsutfall hos patienter med ärrvävnad i hjärtat. För att närmare studera sjukdomsförloppen användes även experimentella djurstudier i avhandlingen.&lt;br/&gt;&lt;br&gt; I delarbete I visades i en djurmodell att små mikroembolier i kranskärlen ger upphov till små infarkter i hjärtat och orsakar nedsatt hjärtfunktion som delvis återhämtas över tid.&lt;br/&gt;&lt;br&gt; I delarbete II visades att storleksbestämning av hjärtinfarkt med två olika MR-tekniker, 2D- och 3D-MR, visar samstämmiga resultat hos patienter men att dessa tekniker överskattar hjärtinfarkten storlek i en djurmodell när hjärtat har tagits ut.&lt;br/&gt;&lt;br&gt; I delarbete III visades att MR överskattar infarktens storlek vid akut hjärtinfarkt men inte vid sju dagar jämfört med referensmetod i en djurmodell. Detta kan förklaras av att peri-infarkt zonen förvinner vid sju dagar och det kan bero på regress av ödem.&lt;br/&gt;&lt;br&gt; I delarbete IV visades att patienter med HCM har sänkt blodtillförsel i områden med förtjockad hjärtmuskelvägg och att blodtillförseln är ytterligare sänkt i områden med ärrvävnad. Studien visade även att områden i hjärtmuskeln med blodbrist ökar när patienterna belastas. Hjärtmuskelns område med blodbrist visade sig även vara större än områden med ärrvävnad, vilket talar för att ärrvävnad uppkommer som följd av blodbrist till hjärtmuskeln.&lt;br/&gt;&lt;br&gt; I delarbete V visades att storleken på gränszonen mellan områden med ärrvävnad och levande hjärtmuskel kan förutsäga vilka patienter som kommer ha nytta av behandling med ICD bättre än idag etablerade kriterier.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis ger denna avhandling ökad insikt kring 1) hjärtinfarkt, 2)hur små blodproppar i kranskärlen påverkar hjärtfunktionen, 3) orsaken till ärrvävnad vid HCM, samt 4) hur MR kan bidra med information om sjukdomsutfall hos patienter med ärrvävnad i hjärtat.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/44cc3a33-9194-4d30-ba7a-280798c00cd7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Assessment_of_myocardial_viability_using_magnetic_resonance_imaging.pdf">https://portal.research.lu.se/files/3056896/5277017.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9449052</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Physiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Magnetic resonance imaging</topic> <topic>myocardial infarction</topic> <topic>hypertrophic cardiomyopathy</topic> <topic>fibrosis</topic> <topic>viability</topic> </subject> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-127-9</identifier> <identifier type="oldLupId">5276989</identifier> <part> <detail type="volume"> <number>2015:48</number> </detail> <extent unit="pages"> <total>99</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-13T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>44cc3a33-9194-4d30-ba7a-280798c00cd7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:56:07+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:56:07+02:00</recordDateApproved> </recordInfo> </mods>

This thesis&lt;br/&gt;&lt;br&gt; aims to look at the regulation of green public procurement (GPP) by&lt;br/&gt;&lt;br&gt; analysing findings from an in-depth case study in a Swedish context, using&lt;br/&gt;&lt;br&gt; interviews with procurement officers as well as analyses of court cases. The&lt;br/&gt;&lt;br&gt; thesis highlights relevant findings to discuss the regulatory context of GPP&lt;br/&gt;&lt;br&gt; in terms of norms and to analyse it in terms of legal rationalities.&lt;br/&gt;&lt;br&gt; Empirical results are presented in the appended articles illustrating&lt;br/&gt;&lt;br&gt; some of the elements of public procurement and GPP. A model for studying&lt;br/&gt;&lt;br&gt; and analysing the findings is developed using norms and legal rationalities&lt;br/&gt;&lt;br&gt; and is subsequently applied using empirical findings presented in the articles.&lt;br/&gt;&lt;br&gt; The final chapter highlights the findings of what structure the regulation&lt;br/&gt;&lt;br&gt; takes in order to cope with the infusion of green into public procurement – a&lt;br/&gt;&lt;br&gt; mixed system of legal rationalities allowing for the generation of necessary&lt;br/&gt;&lt;br&gt; knowledge to compensate for cognitive limitations.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Offentlig upphandling blir alltmer intressant och relevant som ämnesområde då dess sanna ekonomiska värde och potentiella inverkan på marknader - genom köpkraft – uppdagas. Det har dessutom blivit ett relevant område för hållbarhetsdiskursen då man har kommit att inse möjligheten att ställa miljökrav inom ramen för den offentliga upphandlingen, samt miljöanpassa upphandlingsprocessen i bredare mening. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Denna avhandling analyserar miljöanpassningen av den offentliga upphandlingen utifrån ett rättssociologiskt perspektiv och undersöker hur miljöanpassningen regleras. Detta görs genom användningen av begreppen normer och rättsliga rationaliteter, vilka tillsammans skapar en modell för att undersöka och analysera de resultat de empiriska studierna frambringat. De empiriska studierna framställs i fem artiklar som tillsammans med en kappa utgör avhandlingen. I kappan behandlas resultaten med hjälp av ovan nämnda begrepp för att analysera vilken form regleringen tar för att hantera miljöanpassningen av den offentliga upphandlingen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den huvudsakliga frågeställningen är: Vilken form tar rätten för att hantera social förändring? Sekundära frågeställningar är:&lt;br/&gt;&lt;br&gt; 1. Hur materialiseras införseln av miljöhänsyn i den offentliga upphandlingen i regleringen av den?&lt;br/&gt;&lt;br&gt; 2. Hur kan regleringen av grön offentlig upphandling förklaras genom begreppet rättsliga rationaliteter?&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingen ges en introduktion till den offentliga upphandlingen och begreppen normer och rättsliga rationaliteter, följt av syfte och avhandlingens disposition. Metoden utgör ett eget kapitel och där beskrivs hur empirin i form av intervjuer med offentliga upphandlare och analyser av rättsfall gått till. Dessutom ges en översikt av de bifogade artiklarna i metodkapitlet, vilka reproducerats i sin helhet i slutet av avhandlingen. Följaktligen beskrivs operationaliseringen av begreppet rättsliga rationaliteter genom att olika normer relateras till de rättsliga rationaliteterna. Regleringen av miljöanpassad offentlig upphandling beskrivs i det efterföljande kapitlet genom olika utvecklingsfaser, med avslutning i nutid, vilket även besvarar den första delfrågeställningen ovan. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Mot slutet av avhandlingen används operationaliseringen som gjordes tidigare för att identifiera vilka rättsliga rationaliteter som träder fram och huruvida någon är dominant inom regleringen av miljöanpassad offentlig upphandling. Detta görs genom att normer identifieras och extraheras ur artiklarna och därefter används för att identifiera rättsliga rationaliteter samt vilken form regleringen av miljöanpassad offentlig upphandling tar. Här besvaras därigenom den andra delfrågeställningen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Slutligen diskuteras slutsatserna och vilken form rätten tar för att hantera social förändring, vilket besvarar den huvudsakliga frågeställningen. En väsentlig slutsats visar på att regleringen har antagit en form som uppmuntrar till genereringen av kunskap inom området miljöanpassad offentlig upphandling.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/97539622-f7a3-4456-9064-dc347ca265ab</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="AvhandlingWedin.pdf">https://portal.research.lu.se/files/3057172/1487450.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">16338365</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Norms</topic> <topic>GreenPublic Procurement.</topic> <topic>Legal Rationality</topic> <topic>Sociology of Law</topic> <topic>Regulation</topic> </subject> <subject authority="lup"> <topic>Law</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Studies in Sociology of Law</title> </titleInfo> <identifier type="issn">1403-7246</identifier> <identifier type="oldLupId">1487409</identifier> <part> <detail type="volume"> <number>32</number> </detail> <extent unit="pages"> <total>198</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-11-14T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>97539622-f7a3-4456-9064-dc347ca265ab</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:56:09+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-28T09:44:33Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:56:09+02:00</recordDateApproved> </recordInfo> </mods>

Together or alone, they are important both to predict T1D and to classify diabetes at the time of clinical onset. The single nucleotide polymorphism (SNP) rs13266634 in the SLC30A8 gene encodes either an arginine (R) or a tryptophan (W) (R325W) at the amino acid (aa) position 325 in the ZnT8 protein. Autoantibodies that recognize ZnT8-arginine (ZnT8RA), ZnT8-tryptophan (ZnT8WA), or both, but restricted by the polymorphic site of the ZnT8 protein are common in newly diagnosed T1D patients. However, the epitope specificity and affinity of ZnT8A are poorly understood. The autoantigenicity of the ZnT8 polymorphism is unique and comparable protein sequence variations are not found for insulin, GAD65 or IA-2. &lt;br/&gt;&lt;br&gt; Neuropeptide Y (NPY) was reported as a minor autoantigen in T1D. This neurotransmitter has a SNP, rs16139, at aa position 7 in the NPY gene. The major allele is coding for leucine (L), and the minor for proline (P). The latter has been associated with impaired glucose tolerance and increased risk for type 2 diabetes (T2D). However, the possible autoantigenicity of the NPY polymorphism in T1D has not been investigated. &lt;br/&gt;&lt;br&gt; The overall aim of this thesis was to investigate the autoantibody epitopes of ZnT8 and NPY in newly diagnosed T1D patients as well as in patients with long-term T1D and T2D.&lt;br/&gt;&lt;br&gt; Our data in paper I and IV suggests that the polymorphic 325 variant is a major determinant of a conformation-dependent ZnT8A epitope. However, human sera with ZnT8-specific autoantibodies against either the R or the W variant did not recognize ZnT8 (318-331) peptides. It was therefore suggested that the conformational epitope recognized by the autoantibodies requires yet other amino acids beyond the 318-331 peptide of ZnT8. In addition, T1D patients with specific ZnT8WA displayed higher affinity compared to patients with specific ZnT8RA as demonstrated in reciprocal competitive displacement experiments. We suggest that future studies should include the ZnT8A variant specificity in both humoral and cellular tests to understand the possible role of autoantibody affinity to predict T1D. &lt;br/&gt;&lt;br&gt; In order to investigate the presence of NPY autoantibody (NPYA) variants (L or P at aa position 7), we developed radiobinding assays for both variants. We identified NPY-LA (23%) and NPY-PA (19%) in long-term T1D and 12% and 23% in T2D patients, respectively. The frequency of NPYA in newly diagnosed T1D patients at 1-18 years of age was 17% for NPY-LA and 24% for NPY-PA. In statistical regression analyses adjusted for gender, HLA and autoantibody status, NPYA were more common in children with older age at onset compared to children at younger age at onset. We suggest that NPYA may prove useful in the screening of young adults and in patients with long-term diabetes. The autoantibody response against the L7P polymorphic site was rarely specific to any of the two amino acid variants. &lt;br/&gt;&lt;br&gt; This thesis has revealed novel insights of the ZnT8A affinity to the 325-epitope and the possible importance of autoantibody affinity in T1D. Novel insights also include NPY as a minor autoantigen of significance to diabetes etiology and pathogenesis. Therefore, both epitope-specific ZnT8 and NPY autoantibodies are suggested to be included in future attempts to identify islet autoimmunity and to predict the clinical onset of autoimmune T1D.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; I Sverige insjuknar två barn i autoimmun diabetes (typ 1 diabetes) varje dag. Typ 1 diabetes (T1D) är en kronisk autoimmun sjukdom som kan få livshotande konsekvenser vid utebliven behandling. Sverige har den högsta incidensen av T1D i hela världen efter Finland. Förutom att den delvis är ärftlig vet man inte vilken eller vilka faktorer som triggar sjukdomen. Sedan mitten av 1920-talet finns behandling i form av insulin, vilken måste injiceras i kroppen i samband med varje måltid under hela livet. Är inte sjukdomen under ständig kontroll kan ett barn få allvarliga komplikationer som hjärnödem och i värsta fall hamna i koma. Insulin är en livsnödvändighet, som inte finns att tillgå i alla delar av världen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Attackerande immunförsvar bryter ned bukspottkörteln&lt;br/&gt;&lt;br&gt; T1D uppkommer för att immunsystemet, som vanligen skyddar oss genom att bekämpa bakterier och virus, istället attackerar frisk vävnad. En av anledningarna till att det händer är att toleransen mot kroppsegen vävnad bryts. Ett exempel är när immunsystemet dödar de insulinproducerande (β celler) cellerna i bukspottskörteln. Bukspottkörteln är ett viktigt organ eftersom det är källan till insulinproduktion och dess reglering. Insulin är ett hormon som utsöndras i respons av en måltid varpå insulinet kan liknas vid en nyckel som låser upp porten till vår vävnad. Utan nyckeln hålls porten stängd och näring från måltiden kan inte passera in i vävnaden. Kroppen kan således inte tillgodogöra sig näringen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Autoantikroppar är viktiga markörer&lt;br/&gt;&lt;br&gt; Det är sedan länge känt att symptom av T1D först uppkommer när ungefär 80-90% av bukspottkörteln är nedbruten och inte längre kan producera tillräckligt med insulin. Nedbrytningen av bukspottkörteln kan starta redan vid 9 månaders ålder eller så sent som efter tonåren. Tiden från att nedbrytningen har startat till insjuknande kan dock variera från veckor till flera år hos personer med risk för att utveckla T1D. Denna obestämda tid representeras av autoantikroppar som är riktade mot särskilda proteiner i bukspottkörteln. Dessa specifika autoantikroppar finns i blodet hos ett barn som kommer att insjukna och kan med hjälp av laboratoriska metoder detekteras. Autoantikroppar fungerar därför som en markör både innan insjuknande (under tiden vid nedbrytning) och vid insjuknande då diagnos fastställs. Det medför att vi idag bättre kan förutspå ett barns utveckling av sjukdomen. Autoantikropparnas roll och varför de finns i blodet är dock ännu okänd.&lt;br/&gt;&lt;br&gt; Det främsta målet med dagens forskning är att förhindra sjukdomsutvecklingen av T1D och därmed kunna rädda bukspottkörteln innan insulinkällan har sinat. I denna avhandling har en del (studie I och IV) fokuserats på att studera autoantikropparna mot Zink transportör 8 (ZnT8A) och den andra delen (studie II och III) på att identifiera en ny autoantikropp riktad mot Neuropeptid Y (NPYA). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Zink transportör 8 (ZnT8) – proteinet med högst specificitet&lt;br/&gt;&lt;br&gt; Under 2007 visade en forskargrupp från USA att ett särskilt protein, ZnT8, i bukspottkörteln agerar måltavla för immunförsvarets attack. ZnT8-proteinets uppgift är att transportera zink in i insulin-vesiklarna i cellerna, vilket i möss har visats vara ytterst nödvändigt för insulinproduktion. Upp till 80 % av de barn som drabbas av T1D har ZnT8A i blodet, men när och hur denna markör uppstår är inte känt. Tre autoantikropps-varianter, mot ZnT8 har hittills upptäckts arginin (R), tryptofan (W) och glutamin (Q). Man kan ha en, två eller alla tre varianter. Vad som orsakar att man får en eller flera är inte klarlagt. Samtliga autoantikropps-varianter har tidigare visats binda till en särskild del (epitop) av ZnT8-proteinet. Denna epitop styrs av en genförändring (polymorfi), som bestämmer vilken variant av R, W eller Q i genomet som man har. ZnT8 autoantikropparna har förmågan att urskilja de olika varianterna i genomet och studier har visat att har man R i genomet så har man oftare R autoantikroppar. Det betyder att de tre varianterna av autoantikropparna kan se skillnad på endast en aminosyra (R, W eller Q) och har därmed extremt hög specificitet. Trots att detta är känt har den exakta epitopen ännu inte identifierats. Syftet i studie I och IV var därför att närmre studera hur ZnT8 autoantikroppar binder till epitopen av ZnT8-proteinet samt mäta autoantikroppsbindingen till epitopen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Neuropeptid Y – ny måltavla för immunförsvaret?&lt;br/&gt;&lt;br&gt; Neuropeptid Y (NPY) är en neurotransmittor som mestadels uttrycks i det centrala nervsystemet, men även i det perifera nervsystemet som innerverar bukspottkörteln. NPY uttrycks tillsammans med insulin i insulin-vesiklar och har till uppgift att bland annat stimulera aptit. Ett flertal studier har identifierat att en särskild polymorfi i NPY-genen var vanligare hos överviktiga och typ 2 diabetes (T2D) patienter. Denna polymorfi medför att man istället för aminosyran Leucin (L) har Prolin (P) på en position i NPY-proteinet. Utöver NPYs roll inom T2D har NPY associerats med T1D. Under 2008 rapporterade en studie att ungefär 9% av nyligen insjuknade typ 1 diabetespatienter hade autoantikroppar mot NPY. Därför var syftet i studie II att utveckla en ny metod för att identifiera NPY autoantikroppar. I studien undersöktes NPY autoantikropparna i patienter som hade haft typ 1 eller typ 2 diabetes under 10-40 år. I studie III studerades NPY autoantikroppar hos patienter som nyligen insjuknat i T1D. Vi ville även studera likheter och skillnader mellan NPY autoantikropparna och de tidigare identifierade autoantikropparna vilka bland annat innefattade de tre ZnT8 autoantikropps- varianterna. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; ZnT8 autoantikropparna skiljer sig i affinitet&lt;br/&gt;&lt;br&gt; I samarbete med ett företag och en annan forskargrupp i Lund producerade vi olika långa delar (peptid och protein) av ZnT8-proteinet. Alla dessa olika proteindelar omfattade den antagna epitopen till vilken ZnT8 autoantikropparna binder. För att identifiera den exakta epitopen samt hur autoantikropparna binder till epitopen utvecklade vi en ny laborativ metod. Metoden tillät oss att studera ZnT8 autoantikropparna i blodet hos nyligen insjuknade typ 1 diabetespatienter. I studie I och IV, rapporterade vi att epitopen av ZnT8 omfattade en större del än vad som tidigare uppskattats. Epitopen omfattade mer än 15 aminosyror och sträcker sig troligen utöver aminosyra position 318 till 331 av ZnT8-proteinet. Vi kunde även bekräfta att ZnT8 autoantikropparna är konformationsberoende. Det betyder att ZnT8-proteinet har en särskild struktur som känns igen av autoantikropparna. Vidare fann vi att ZnT8W autoantikropps-varianten hade starkare bindning (högre affinitet) till ZnT8-proteinet i jämförelse med ZnT8R autoantikropps-varianten hos patienter med T1D. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; NPY autoantikroppar finns i blodet hos patienter med typ 1 diabetes&lt;br/&gt;&lt;br&gt; I studie II utvecklades två laborativa antikropps-metoder som skulle kunna identifiera två varianter av NPY autoantikroppar, Leucin (L) och Prolin (P). Metoderna verifierades i labbet och ansågs ha en hög precision. Vi fann att patienter som haft typ 1 eller typ 2 diabetes i upp till 40 år hade NPY autoantikroppar i blodet. NPY autoantikropparna kunde identifieras hos 29% av T1D patienterna i jämförelse med 13% av T2D patienterna. 15% av patienterna med T1D hade båda varianterna av autoantikroppar, NPY-L och NPY-P. &lt;br/&gt;&lt;br&gt; Utöver våra fynd i studie II identifierade vi att 26% av nyligen insjuknade T1D patienter hade NPY autoantikroppar (studie III). NPY autoantikropparna var vanligare bland barn som var äldre än 10 år vid diagnostillfället i jämförelse med barn som var yngre än 10 år. NPY autoantikropparna visade sig även förekomma oftare bland flickor än hos pojkar. Genom att analysera T1D patienter för NPY autoantikroppar kunde ca 1% av de tidigare autoantikropps-negativa patienterna betraktas som autoantikropps-positiva. Således bidrog NPY autoantikroppen till en förbättrad diagnostisk känslighet, vilket betyder att NPY autoantikroppen som ensam markör skulle kunna identifiera barn som riskerar att utveckla T1D.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Slutsats och framtidsperspektiv&lt;br/&gt;&lt;br&gt; Sammanfattningsvis så har vi utvecklat två nya metoder. Dessa har tillåtit oss att studera ZnT8 autoantikroppars affinitet samt att identifiera en ny autoantikropp riktad mot neurotransmittorn, NPY, hos patienter med T1D. Vi fann att affiniteten skiljer sig beroende på vilken variant av ZnT8 autoantikropp T1D patienter hade. Det har spekulerats om att affiniteten av autoantikroppar kan vara viktig eftersom den kan ha betydelse vid utvecklingen av T1D. Vi anser därför att fler affinitets-studier av autoantikroppar bör genomföras för att se huruvida affinitet kan bidra till att förutspå att ett barn kommer att insjukna i T1D. Vi har även visat att NPY autoantikroppar både finns hos patienter med lång duration och bland dem som nyligen har insjuknat i T1D. Vi påvisade även NPY autoantikroppar hos patienter som inte hade någon av de andra autoantikropparna. Vi föreslår att analys av NPY autoantikroppar bör göras som ett komplement till redan etablerad autoantikropps-analys. Detta skulle kunna gynna personer som vid diagnostillfället inte har identifierats med andra autoantikroppar, eller som har en ökad risk att insjukna. Kostnaden av NPY autoantikropps-analysen bör dock vägas mot nyttan av att identifiera autoantikropps-positiva individer vid diagnos.&lt;br/&gt;&lt;br&gt; Slutligen är det av stor betydelse att öka vår kunskap om diabetesrelaterade markörer, såsom autoantikroppar, eftersom de är viktiga diagnostiska verktyg. Genom att studera autoantikropparnas roll för att förutspå T1D kan vi förhindra att barn som håller på att insjukna hamnar i ett livshotande tillstånd.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/aa14180c-3520-4969-a02a-34cdcc7275a7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="HANNA_S_AVHANDLING_140409.pdf">https://portal.research.lu.se/files/3058326/4406530.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2567211</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Minor autoantigens Neuropeptide Y.</topic> <topic>Affinity</topic> <topic>ZnT8 autoantibodies</topic> <topic>Autoimmune (type 1) diabetes</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-83-0</identifier> <identifier type="oldLupId">4406288</identifier> <part> <detail type="volume"> <number>2014:57</number> </detail> <extent unit="pages"> <total>184</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-05-16T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>aa14180c-3520-4969-a02a-34cdcc7275a7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:56:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:56:19+02:00</recordDateApproved> </recordInfo> </mods>

HAMLET causes apoptosis but cells die even if this pathway is inhibited. Thus, the role of autophagy, an alternative cell death pathway, was examined. During autophagy double membrane-enclosed autophagosomes form around cellular material and deliver it to the lysosomes for degradation. After HAMLET treatment, such vesicles were observed and HAMLET also increased granular LC3-GFP staining confirming autophagosome accumulation. In addition, the autophagic form of LC3 increased if lysosomal degradation was inhibited, indicating a true increase in autophagic flux. Several factors that may activate autophagy were identified, including mitochondrial damage, inhibition of the autophagy inhibitor mTOR and increased the expression of autophagy components. Inhibition of autophagy by Atg5 and Beclin-1 siRNAs reduced cell death suggesting that autophagy is an important part of the cell death programme. As autophagy can be initiated by metabolic stress and as metabolism is altered in cancer cells we investigated if HAMLET-induced cell death involves an effect on metabolism. Healthy cells, which were less sensitive to HAMLET, had lower levels of c-Myc, an important regulator of glucose metabolism, and knockdown of c-Myc in cancer cells reduced their sensitivity. In contrast, cancer cell death was enhanced by glycolysis inhibition. HAMLET was also shown to bind the glycolytic enzyme hexokinase 1 (HK1) and to reduce HK activity, ATP levels and lactate release. Also, knockdown of HK1 and the glycolysis-enhancing HIF1A sensitized cancer cells to HAMLET whereas knockdown of the glycolysis-regulating protein PFKFB1 reduced sensitivity. Finally, mass spectrometry-based analysis indicated that HAMLET has a broad impact on metabolism possibly due to binding of HK1. In an additional screen for HAMLET-binding proteins prohibitin-2, a multifunctional protein found at the same cellular sites as HAMLET, was identified. The binding was confirmed in vitro and HAMLET was shown to also bind to the related prohibitin. Co-staining for HAMLET and prohibitins revealed colocalization in the cytoplasm. In addition, nuclear staining for both prohibitins was reduced, as described in camptothecin-induced cancer cell death. Furthermore, prohibitin-2 siRNA reduced cell death after HAMLET treatment suggesting that prohibitins may play a role in HAMLET-induced cell death. Besides cell death, HAMLET also causes cancer cell detachment and α-actinin-4, which crosslinks the actin cytoskeleton and focal adhesions, was identified in a screen as a potential HAMLET target. The binding between HAMLET and α-actinins was confirmed by co-immunoprecipitation and the actin and integrin binding sites on α-actinin were identified as possible sites of HAMLET binding in a peptide binding assay. HAMLET was also shown to colocalize with α-actinin-4 in the cell periphery and to reduce its granular surface staining and intracellular trabecular staining. In addition, HAMLET altered the staining of other focal adhesion components and reduced the level of active focal adhesion kinase and ERK, which can both be regulated via focal adhesions. Healthy cells did not detach after HAMLET treatment but the detachment of cancer cells was even further enhanced by knockdown of α-actinins. In contrast, overexpression of α-actinin-4-GFP delayed blebbing and rounding up further suggesting that α-actinin is involved in HAMLET-induced detachment. In summary, this study indicates that HAMLET activates autophagy and disrupts metabolism at least partly by binding to HK1 and that these events contribute to cell death. The results also suggest that c-Myc and glycolysis are important determinants of HAMLET sensitivity. Furthermore, the study identifies prohibitins as novel HAMLET targets with a potential role in cell death and suggests that HAMLET binding to α-actinins disrupts focal adhesions leading to cell detachment.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ee725c65-bbe7-4fd1-a09c-e1dc1a19ee35</url> </location> </relatedItem> <originInfo> <publisher>Division of Microbiology, Immunology and Glycobiology - MIG</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>alpha-actinin</topic> <topic>prohibitin</topic> <topic>alpha-lactalbumin</topic> <topic>HAMLET</topic> <topic>cancer</topic> <topic>cell death</topic> <topic>autophagy</topic> <topic>focal adhesions</topic> <topic>c-Myc</topic> <topic>hexokinase</topic> <topic>glycolysis</topic> </subject> <subject authority="lup"> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-68-9</identifier> <identifier type="oldLupId">1590156</identifier> <part> <detail type="volume"> <number>2010:53</number> </detail> <extent unit="pages"> <total>156</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-08T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>ee725c65-bbe7-4fd1-a09c-e1dc1a19ee35</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:56:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:56:24+02:00</recordDateApproved> </recordInfo> </mods>

The work was done as a part of the resource manager component of the adaptive resource management framework implemented in the European ACTORS project. The framework dynamically allocates CPU resources for the applications. The key element of the framework is the resource manager that combines feedforward and feedback algorithms together with reservation techniques. The resource requirements of the applications are provided through service level tables. Dynamic bandwidth allocation is performed by the resource manager which adapts applications to changes in resource availability, and adapts the resource allocation to changes in application requirements. The dynamic bandwidth allocation allows to obtain real application models through the tuning and update of the initial service level tables.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The second part of the thesis deals with the design of measurement noise filters for PID control. The design is based on an iterative approach to calculate the filter time constant, which requires the information in&lt;br/&gt;&lt;br&gt; terms of an FOTD model of the process. Tuning methods such as Lambda, SIMC, and AMIGO are used to obtain the controller parameters. New criteria based on the trade-offs between performance, robustness, and attenuation of measurement noise are proposed for assessment of the design. Simple rules for calculating the filter time constant based on the nominal process model and the nominal controller are then derived, thus, eliminating the need for iteration. Finally, a complete tuning procedure is proposed. The tuning procedure accounts for the effects of filtering in the nominal process. Hence, the added dynamics are included in the filtered process model, which is then used to recalculate the controller tuning parameters.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7a4b94d7-ee4c-4413-9e38-8360aec74549</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis.pdf">https://portal.research.lu.se/files/3058943/4362742.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4619884</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>resource management</topic> <topic>embedded systems</topic> <topic>real-time systems</topic> <topic>multimedia</topic> <topic>multicore</topic> <topic>measurement noise</topic> <topic>filtering</topic> <topic>trade-offs</topic> <topic>robustness</topic> <topic>performance</topic> <topic>SDU</topic> <topic>noise gain</topic> <topic>PID control</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>PhD Thesis TFRT-1100</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="issn">0280-5316</identifier> <identifier type="isbn">978-91-7473-969-5</identifier> <identifier type="oldLupId">4362724</identifier> <part> <extent unit="pages"> <total>207</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popsciencePopulärvetenskaplig sammanfattning.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3058941/4362745.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-04-23T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>7a4b94d7-ee4c-4413-9e38-8360aec74549</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:56:27+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-23T09:06:48Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:56:27+02:00</recordDateApproved> </recordInfo> </mods>

In the beginning of the study all persons in the Southern Health Care Region in Sweden diagnosed with colon, rectal, breast, prostate and lung cancer during the period 2000 to 2005 were identified via the Swedish Cancer Register. Lately, including the period 2006 to 2007, all persons diagnosed with cancer were analysed with specification of 18 types of cancer. The obtained information was linked to other population based registries. Comorbidity diagnoses for patients and all data for up to 8 eight control persons were also extracted from health care registries in Skåne. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Results showed that the major part of health care costs for prostate and lung cancer patients occurred during the first year following the diagnosis. A clear difference was seen between costs for survivors and patients who later died. For patients with prostate cancer health care costs increased with higher Gleason score (rate of aggressiveness) in the year following the diagnosis. Higher health care costs were seen for patients treated with primary radiotherapy and costs were higher for patients with curative treatments compared to those with palliative treatments. For patients with lung cancer the costs totally were declining with higher stage. Highest health care costs were seen for patients treated with endoscopic therapy of the bronchus. Health care costs were higher for operated patients compared to those with treatments only by chemotherapy or radiotherapy.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Higher survival in patients with non-small cell lung cancer (NSCLC) was explained by surgery, short waiting time, treatments by chemotherapy or radiotherapy and patients living in a specific geographic area. Lower survival was connected to no treatment, tumour stage, performance status and alcoholic related diseases. Overall a diagnosis of dementia was significantly less common among the cancer cases. Because the effect was seen for all tumour types and especially for patients older than 70 years and since the deficit was more pronounced for patients with tumours situated within the body, the data suggest that malignancies are underdiagnosed for persons with dementia. Diabetes was significantly more common prior to diagnosis in patients with liver, pancreatic, colon and urinary tract/bladder cancer and in patients with breast cancer diagnosed with diabetes 0–4 years prior to the cancer diagnosis. A lower risk of diabetes was seen in patients with prostate carcinoma among individuals with diabetes diagnosed 5–10 years prior to the cancer diagnosis. Obesity was significantly more common in patients with endometrial, colon and kidney cancer and with breast cancer above the age of 60 years in those where obesity was diagnosed close to the diagnosis of cancer. High blood lipids were significantly more common in patients with ovarian cancer and less common in patients with breast cancer. From a public health view avoiding overweight and obesity, as well as preventing type II diabetes mellitus, are important in preventing cancer and other diseases. Measures should be taken early on and should be based on healthy eating and physical activity patterns throughout life. Health care consumption and health care costs for partners increased in the years following the cancer diagnosis of the person with cancer especially for partners to colon, prostate and lung cancer patients. The number of diagnoses increased significantly among partners in the whole sample with the largest increase in psychiatric diagnoses. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the future, new treatments, especially new pharmacy, are to change the relationship between treatments, costs and survival. It is of importance further examine in what way results are affected by how the patient contacts the health care system, the patient´s lifestyle and socioeconomic background or the health care system itself (organisation, competence etc). Furthermore, the new knowledge concerning cancer and comorbidities may provide an insight into the mechanisms of tumour development. Postponing the onset of comorbidity may also prevent/postpone the diagnosis of cancer. Further research is needed to learn more about the situation of the partner and to identify persons at risk of psychiatric morbidity. Knowledge is also needed on how to support the partner in the most efficient way. When planning for care and allocation of resources for care the impact on the partner should also be considered.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Södra Regionvårdsnämnden har önskat att få belyst om vi har en rättvis och jämlik cancervård i Södra sjukvårdsregionen. Därför har en populationsbaserad registerstudie med många olika etapper genomförts. Basinformationen har hämtats från Tumörregistret i Södra sjukvårdsregionen. Första diagnosdatum noterades och hemort (kommun, distrikt, län) samt sjukhus definierades efter registreringarna vid detta första diagnosdatum. I inledande etapper användes data för åren 2000-2005 för patienter som diagnostiserats med de fem vanligaste cancerformerna: kolon-, rektal-, bröst- prostata- och lungcancer (ca 50 % av all cancer). I senare etapper breddades studien genom att ta med alla cancerformer och data avsåg då även åren 2006-2007.&lt;br/&gt;&lt;br&gt; Delstudierna har på olika sätt kompletterats med data från befolkningsregistret, olika patientregister, läkemedelsregistret (förmån, öppen vård), kvalitetsregister avseende prostata- respektive lungcancer, vård- och kostnadsdata i Region Skåne (sjukhusvård/offentlig primärvård/privat vård) och även försäkringskassans register över sjukdagar/-episoder (i tilläggsartiklar).&lt;br/&gt;&lt;br&gt; Studien har belyst insjuknande, omfattning och lokalisering av vård, överlevnad och kostnader för cancerpatienter/anhöriga i Södra sjukvårdsregionen. Analyser har gjorts avseende händelser som kan indikera bättre möjligheter till snabbare diagnos och lika behandling oavsett var man bor i regionen (har endast presenterats i en rapport). Särskilda kostnadsjämförelser har gjorts för de som har överlevt jämfört med de som avlidit. Analyser gjordes över samband mellan personers andra sjukdomar och den cancer man insjuknat i för att ta reda på om personer som var multisjuka (hade komorbiditet) hade större risk att insjukna i cancer. Vidare har kostnadsanalyser gjorts av olika behandlingar av prostata- och lungcancer. Överlevnad beräknades från diagnosdatum i dagar. Patientens hemort analyserades som bostadsort vid diagnos. Fördjupad analys över dödligheten har gjorts för patienter som insjuknat i lung cancer.&lt;br/&gt;&lt;br&gt; Säkerställda skillnader mellan olika befolkningsområden har påvisats för de fem stora cancerformerna avseende insjuknande, främst lungcancer och i överlevnad/dödlighet, främst avseende prostata- och lungcancer. Män hade klart lägre överlevnad än kvinnor vid kolon-, rektal- och lungcancer. I den utvidgade studien fanns på motsvarande sätt säkerställda skillnader mellan befolkningsområden i dödlighet även för bl a malignt lymfom och levercancer. Resultaten har redovisats i fyra olika rapporter.&lt;br/&gt;&lt;br&gt; Samband mellan 18 olika cancerformer och demens, diabetes, fetma och onormala blodfetter har analyserats. Diagnosen demens var klart lägre hos cancerpatienterna än hos kontrollgruppen. Säkerställda resultat var för sig uppnåddes för: koloncancer, prostatacancer, lungcancer, melanom och cancer i urinblåsan eller i urinvägarna. Sammantaget förekom demens i 40 procent lägre omfattning bland personerna med cancer. Ju längre in i kroppen tumörerna har suttit, desto lägre var förekomsten bland dementa. Detta tyder på att man inte tittar efter ordentligt hos patienterna med demens och för den gruppen bara diagnostiserar de tumörer som är lätta att upptäcka.&lt;br/&gt;&lt;br&gt; Samtidigt har de som har diabetes, fetma eller onormala blodfetter betydligt större risk att få olika former av cancer. För de senare sjukdomsgrupperna gjordes även både enkla och kombinerade analyser dvs de som hade diabetes jämfördes med kontroller samtidigt som de som hade t ex både diabetes och fetma också jämfördes med kontroller. De som insjuknar i diabetes visade sig ha en ökad risk att senare drabbas av bröstcancer samt cancer i lever, tjocktarm, bukspottkörtel och urinblåsa. Hos de som lider av fetma är det vanligare med cancer i livmodern, tjocktarm och njure samt för dem över 60 även bröstcancer.&lt;br/&gt;&lt;br&gt; För patienter med prostata fanns en stor skillnad mellan kostnader för överlevande och avlidna patienter. Sjukvårdskostnaderna steg med högre Gleason-score (sjukdomsgrad) året efter diagnostillfället. Högst sjukvårdkostnader konstaterades för patienter som fick strålbehandling. Lägst kostnader hade patienterna som inte fick någon behandling. Patienter med kurativ behandling hade högre kostnader än de som fick palliativ behandling. Anhöriga ökade sin sjukvårdskonsumtion både det första och det andra året efter att patienten fått sin prostata-cancerdiagnos innebärande ökade sjukvårdskostnader.&lt;br/&gt;&lt;br&gt; Större delen av kostnaderna för patienter med lung cancer uppstår första året efter diagnos. Det fanns även här stor skillnad i kostnader för de som överlever och de som senare avlider. Patienter som opererats hade högre kostnader jämfört med de som endast fick cellgifter eller som strål-behandlades. Totalt sjönk kostnaden ju svårare sjuk patienten var.&lt;br/&gt;&lt;br&gt; En problematik vid kostnadsanalyser är att kostnader för läkemedel vid utprovning/test i särskilda studier och som då bekostas av läkemedelsföretag oftast inte finns med i redovisningen. När kostnaderna för olika behandlingar jämförs med överlevnadstiden för behandlingarna fanns en del svårförklarliga resultat som kräver ytterligare studier för man ska kunna dra några slutsatser.&lt;br/&gt;&lt;br&gt; Eftersom det hade påvisats stora skillnader i överlevnad/dödlighet för patienter med lungcancer i den inledande studien gjordes en analys för att undersöka hur olika faktorer påverkar utfallet. Hög dödlighet förklaras främst av att patienten inte fått någon behandling, har dåligt allmäntillstånd eller har insjuknat i ett avancerat sjukdomsstadium. De mest ‖skyddande‖ faktorerna är om patienten blivit opererad eller haft kort remisstid från besök till behandling. Här visades också att befolkningen i de geografiska områden som i grundstudien hade högre dödlighet fortfarande hade detta även när hänsyn togs olika bakgrundsfaktorer.&lt;br/&gt;&lt;br&gt; För anhöriga visar resultatet en ökad vårdkonsumtion och ökade vårdkostnader tiden efter patientens cancerdiagnos hos framförallt anhöriga till patienter med koloncancer och lungcancer. Antalet sjukdomsdiagnoser ökade signifikant för hela anhöriggruppen med 24 % året efter den cancersjukes diagnos. Psykiatriska diagnoser ökade signifikant hos anhöriga till kolon-, lung- och prostatacancer.&lt;br/&gt;&lt;br&gt; Lungcancerpatienterna hade högst och patienterna med prostatacancer lägst antal sjukskrivnings-dagar. Patienter med anhöriga hade 48 % fler sjukskrivningsdagar än de som var utan anhörig. Anhöriga till lungcancersjuka hade störst antal sjukskrivningsepisoder och antal sjukdagar, och en jämförelse med normalbefolkningen visade att en signifikant ökning av sjukskrivning för denna grupp med 76 %.

The main study area was Kriegers Flak in the southwestern Baltic Sea where pre-Late Weichselian sediments were identified. We suggest that the lowermost till on Kriegers Flak, dated to the Early or Middle Weichselian, was deposited during the Ristinge advance, which implies an age of c. 55-50 ka. Following the deglaciation after this advance, isostatic depression enabled a marine influence in the southern Baltic Basin. During this time Kriegers Flak unit A, with a low-diversity benthic foraminifera fauna indicative of cold water and low salinities, was deposited. This was followed by a forced regression on Kriegers Flak, probably caused by a combination of isostatic rebound and a falling global sea level. Between 42 and 36 cal. ka BP wetlands and shallow lakes existed on Kriegers Flak (unit B). Macrofossil and pollen from this unit suggest tundra-like, or forest tundra-like vegetation, possibly with birch and pine in sheltered locations. From 28.5 to 26 ka, a thick succession of glaciolacustrine clay, unit C, was deposited at Kriegers Flak indicating a damming the Baltic Basin by an ice advance into Kattegat.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The upper part of the stratigraphy has been reconstructed from published and new terrestrial sections in Skåne. Here three tills are identified. The lowermost, the Allarp Till, was deposited after the damming of the Baltic Basin at c. 30 ka. It was followed, after a deglaciation, by deposition of the Dalby Till, representing the Last Glacial Maximum advances including an early advance from southeast, the main advance from northeast and the first Young Baltic advances from southeast. The uppermost till, the Lund Till was deposited by the Öresund advance after a deglaciation.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The deglaciation of southern Sweden was dated using cosmogenic nuclide surface exposure dating. We suggest that central Skåne was deglaciated between 17 and 16 ka. The deglaciation in southern Småland was dated to 15.6±0.8 and 16.6±0.9 ka, while a site in northern Småland was dated to 14.6±1.0 ka. Our northernmost site, situated only 25 km south of the Younger Dryas Moraine, was dated to c. 13.8±0.8 ka while cosmogenic surface exposure ages from Gotland suggest a deglaciation before 13.0±0.8 ka.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Genom att studera forna inlandsisar kan vi få en inblick i hur en inlandsis påverkar och påverkas av till exempel klimatförändringar och havsnivåvariationer i tidsperspektiv från hundratals till hundratusentals år. I Skandinavien är det framförallt spåren efter nedisningar under den senaste istiden, Weichsel-istiden, som bevarats. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I den här studien fokuserar vi på Östersjöns och sydligaste Sveriges historia under den senaste istiden. Östersjöns tidiga istidshistoria, innan den Skandinaviska inlandsisen lämnade området, har varit i det närmaste okänd eftersom den Skandinaviska inlandsisen eroderade och omformade tidigare avsatta sediment. Dessutom finns det få riktigt djupa borrkärnor i Östersjön och de sediment som trots allt identifierats i och kring Östersjön är ofta svåra att åldersbestämma och kan inte alltid jämföras mellan olika regioner och länder.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har här använt borrkärnor ifrån Kriegers Flak, ett grundområde beläget ca 30 km söder om Trelleborg i sydvästra Östersjön. Det här området befinner sig i den södra delen av den Skandinaviska inlandsisens maximala utbredning under den senaste istiden vilket innebär att det endast var istäckt under de mer omfattande nedisningarna ochisfritt i långa perioder däremellan. I den understa, och därmed äldsta, delen av borrkärnorna hittar vi berggrunden som i området består av kritkalksten. Direkt ovanpå hittar vi en morän som markerar den äldsta bevarade isframstöten över Kriegers Flak. Vi kopplar den till den första kända isframstöten i östra Danmark under den senaste istiden vilket skulle innebära att den är ca 55–50 tusen år gammal eller möjligen något äldre.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; När isen smälte bort fylldes västra Östersjön av en blandning av smältvatten från den tillbakasmältande isen och havsvatten från Atlanten. Genom att studera bottenlevande skalamöbor, foraminifererer, vars skal bevarats i sedimenten, kan vi se att de levde i en miljö där låga vattentemperaturer och salthalter innebar att bara de mest tåliga arterna kunde etablera sig.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Nästa bevarade enhet avsattes för mellan 42 och 36 tusen år sedan. Skalfragment, växtdelar och insektsfragment som bevarats i sedimenten visar att material som idag ligger 35-40 m under vattenytan, avsattes på land i våtmarker och grunda sjöar och att stora delar av Östersjön måste ha varit torrlagd. Istället fanns där för ca 40 tusen år sedan en trädlös tundra, möjligen med björk och tall i skyddade lägen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För ungefär 30 tusen år sedan började så inlandsisen att växa igen och is ifrån södra Norge rörde sig söderut och dämde Kattegatt och därmed hela Östersjön så att en sjö bildades och vattennivån höjdes. Tjocka lerlager på Kriegers Flak, avsatta för mellan 28,5 och 26 tusen år sedan, visar att området översvämmades på nytt. Även i Östersjön växte isen och rörde sig över sydligaste Skåne och ostligaste Danmark vid ett eller två tillfällen vid ungefär den här tiden. Det är dock oklart om det skedde före eller efter att leran avsattes på Kriegers Flak.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För ca 22 tusen år sedan var den Skandinaviska inlandsisen som störst i sin västra del och nådde då ända till centrala Jylland i Danmark och söder om Berlin i östra Tyskland. När den sedan började smälta tillbaka skedde det inte i en jämn takt utan is fortsatte att röra sig genom Östersjön och ryckte flera gånger fram på nytt över områden i östra Danmark och sydligaste Skåne som den tidigare lämnat.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har daterat de sista skedena av den senaste istiden i Sydsverige, perioden då isen gradvis smälte tillbaka, med hjälp av exponeringsdateringar. Det är en metod som bygger på att ett stenblock eller en klippa som ligger vid markytan ständigt utsätts för kosmisk strålning. Denna strålning bildar bland annat 10Be i stenen som sedan kan mätas. Ju mer 10Be, desto längre har blocket eller bergytan exponerats. En inlandsis kan nollställa räkneverket, antingen genom att erodera berget så att en ny yta exponeras eller genom att placera block vid ytan som inte tidigare exponerats. En stor fördel med metoden är därför att den kan mäta själva bildandet av landformen medan många andra dateringar av glaciala landformer bygger på att hitta daterbart material som är äldre och eller yngre än landformen som man egentligen är intresserad av.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Våra dateringar tyder på att Kullahalvön i nordvästra Skåne blev isfri för mellan 17 och 18 tusen år sedan, följt av centrala Skåne mellan 16 och 17 tusen år sedan. De sydligaste delarna kan dock fortfarande ha varit istäckta i och med att is fortsatte att röra sig genom Östersjön. Isen drog sig sedan tillbaka mot nordost och södra Småland verkar ha blivit isfritt för ungefär 15,6–16,6 tusen år sedan, Vimmerbytrakten för ungefär 14,5 tusen år sedan och nordligaste Småland för omkring 13,8 tusen år sedan.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Tillsammans ger studierna presenterade i den här avhandlingen en inblick i Östersjön och södra Sveriges istidshistoria med början för ca 55 tusen år sedan och fram till dess att den Skandinaviska inlandsisen slutligen lämnade Sydsverige för knappt 14 tusen år sedan.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/15f34a1c-d581-466d-9275-2b2744dc2b02</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa.pdf">https://portal.research.lu.se/files/3060542/3290112.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9286184</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Geology, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Geology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lundqua thesis</title> </titleInfo> <identifier type="issn">0281-3033</identifier> <identifier type="issn">0281-3033</identifier> <identifier type="isbn">978-91-86746-81-0</identifier> <identifier type="oldLupId">3290098</identifier> <part> <detail type="issue"> <number>67</number> </detail> <extent unit="pages"> <total>18</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-01-18T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>15f34a1c-d581-466d-9275-2b2744dc2b02</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:56:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:56:41+02:00</recordDateApproved> </recordInfo> </mods>

The ABAQUS&lt;br/&gt;&lt;br&gt; program was used for this purpose. Concrete was modelled using a plastic damage model.&lt;br/&gt;&lt;br&gt; Steel bars were modelled as an elastic perfectly plastic material, with perfect bond between&lt;br/&gt;&lt;br&gt; concrete and steel. A cohesive model was used for modelling the FRP-concrete interface.&lt;br/&gt;&lt;br&gt; Bond properties needed as input to the cohesive model, such as initial stiffness, shear strength&lt;br/&gt;&lt;br&gt; and fracture energy were proposed based on fitting FEM results to experimental results from&lt;br/&gt;&lt;br&gt; literature. Initial stiffness was related to the adhesive properties. Shear strength and fracture&lt;br/&gt;&lt;br&gt; energy were expressed as functions of tensile strength of concrete and of adhesive properties.&lt;br/&gt;&lt;br&gt; Experimental tests were performed to investigate the behaviour of retrofitted beams. The&lt;br/&gt;&lt;br&gt; model was verified through comparison with the experimental data regarding failure mode&lt;br/&gt;&lt;br&gt; and load-displacement behaviour.&lt;br/&gt;&lt;br&gt; The influence of several parameters such as length and width of FRP and properties of the&lt;br/&gt;&lt;br&gt; adhesive were investigated. The result showed that when the length of FRP increases, the load&lt;br/&gt;&lt;br&gt; capacity of the beam increases for both shear and flexural strengthening. The result also&lt;br/&gt;&lt;br&gt; showed that the FRP to concrete width ratio and the stiffness of FRP affect the failure mode&lt;br/&gt;&lt;br&gt; of retrofitted beams. The maximum load increases with increased width ratio. Increased FRP&lt;br/&gt;&lt;br&gt; stiffness increases the maximum load only up to a certain value of the stiffness, and thereafter&lt;br/&gt;&lt;br&gt; the maximum load decreases. The maximum load also increases when the stiffness of&lt;br/&gt;&lt;br&gt; adhesive decreases.&lt;br/&gt;&lt;br&gt; An improvement of the calculation of interfacial shear stress at plate end in a design rule&lt;br/&gt;&lt;br&gt; for simply supported beams bonded with FRP was proposed. The proposed design rule was&lt;br/&gt;&lt;br&gt; applied to an existing defective beam and the result was verified using the FEM model.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Concrete is one of our most common building materials and is used both for buildings,&lt;br/&gt;&lt;br&gt; bridges and other heavy structures. Typically, concrete structures are very durable, but&lt;br/&gt;&lt;br&gt; sometimes they need to be strengthened. The reason may be cracking due to environmental&lt;br/&gt;&lt;br&gt; effects, that a bridge is to be used for heavier traffic, new building codes, or damage resulting&lt;br/&gt;&lt;br&gt; from earthquakes.&lt;br/&gt;&lt;br&gt; Concrete is a material that can withstand compressive loads very well but is sensitive to&lt;br/&gt;&lt;br&gt; tensile forces. Therefore, concrete structures are typically reinforced by casting in steel bars in&lt;br/&gt;&lt;br&gt; areas where tension can arise. This cannot be done afterwards, and one strengthening method,&lt;br/&gt;&lt;br&gt; is therefore to glue reinforcement on the exterior of the structure in the areas exposed to&lt;br/&gt;&lt;br&gt; tension.&lt;br/&gt;&lt;br&gt; Fibre composite can be used in reinforcing concrete structures externally. Fibre composite&lt;br/&gt;&lt;br&gt; materials have low density, can be easily installed and are easy to cut to length on site.&lt;br/&gt;&lt;br&gt; Therefore, fibre composite as external reinforcement for concrete structures has become very&lt;br/&gt;&lt;br&gt; attractive and popular around the world.&lt;br/&gt;&lt;br&gt; It is important to understand the behaviour of a strengthened structure well and realize&lt;br/&gt;&lt;br&gt; what parameters affect the failure mode and load-bearing capacity. The aim of this thesis is&lt;br/&gt;&lt;br&gt; therefore to investigate and improve the understanding of the behaviour of reinforced concrete&lt;br/&gt;&lt;br&gt; beams strengthened with fibre composite.&lt;br/&gt;&lt;br&gt; These structures have a critical problem implying that they may fail in a sudden manner.&lt;br/&gt;&lt;br&gt; This failure involves separation between composite and concrete. Special attention is paid to&lt;br/&gt;&lt;br&gt; this phenomenon, which is called debonding.&lt;br/&gt;&lt;br&gt; One scope of this study was to develop computer modelling framework. Therefore, three&lt;br/&gt;&lt;br&gt; dimensional computations were conducted considering the nonlinear behaviour of the&lt;br/&gt;&lt;br&gt; materials. A new model for the concrete-fibre composite interface was included.&lt;br/&gt;&lt;br&gt; The computations were verified against experiments. The results confirmed the ability of&lt;br/&gt;&lt;br&gt; the computations to recreate the load-deflection behaviour, the crack distribution, and the&lt;br/&gt;&lt;br&gt; failure modes. Simulations and experiments showed that application of fibre composite can&lt;br/&gt;&lt;br&gt; increase the load capacity and the stiffness of the beams.&lt;br/&gt;&lt;br&gt; The influence of several parameters such as length and width of fibre composite and&lt;br/&gt;&lt;br&gt; properties of adhesive were investigated. Large width and length of fibre composite and soft&lt;br/&gt;&lt;br&gt; adhesive would yield to reduce tendency of debonding and increase thus of the utilization of&lt;br/&gt;&lt;br&gt; fibre composite and increase load capacity.&lt;br/&gt;&lt;br&gt; The findings from this study yield a proposal for a modification of design code rules.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e731ca6b-e517-4e8d-9a83-4fde23a310a0</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Dissertation1.pdf">https://portal.research.lu.se/files/3060710/2203686.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4887659</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Construction Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011-11</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Mechanical Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>TVSM-1000</title> </titleInfo> <identifier type="issn">0281-6679</identifier> <identifier type="isbn">978-91-7473-194-1</identifier> <identifier type="oldLupId">2203666</identifier> <part> <detail type="issue"> <number>TVSM-1023</number> </detail> <extent unit="pages"> <total>163</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-12-06T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>e731ca6b-e517-4e8d-9a83-4fde23a310a0</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:56:44+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:56:44+02:00</recordDateApproved> </recordInfo> </mods>

The thesis focuses on referential subjects, and addresses the problem of why the possibilities to leave out such subjects have been reduced during the history of Swedish. The dissertation consists of three main parts, divided into eight chapters. In the first part, chapters 1–3, the aims are presented and a theoretical background to the research on diachronic syntax is given. Furthermore, a brief overview presents the main trends in scientific work in this area, in which two main directions crystallize: on the one hand theories that have related subject omission to morphological factors and on the other hand theories that regard contextual aspects as crucial.&lt;br/&gt;&lt;br&gt; Chapter 4 presents the second part of the thesis and consists of an empirical study of subjectless clauses in the history of Swedish. A corpus of about 193,400 words was collected from 12 Old Swedish texts, and on the basis of a random sample, a variable rule analysis was carried out. Although the investigations show that subjectless clauses occur most frequently in Early Old Swedish (1225–1375), the most striking change in the use of subjectless clauses during Old Swedish seems to be related to the subject position (Spec, IP): whereas referential subjects could be omitted from this position in Early Old Swedish, corresponding subjectless clauses are uncommon in Late Old Swedish. Since this change takes place before the loss of person agreement, it seems reasonable to assume that this syntactic change cannot be related to deflection. &lt;br/&gt;&lt;br&gt; The central task of the third part of the thesis, presented in chapters 5–8, is to explain why subject omission from Spec, IP has been limited in Swedish. It is argued that omission of subjects in verb second main clauses and subordinate clauses is an effect of movement strategies. Whereas the movement to Spec, IP is syntactically determined in Modern Swedish, the corresponding move is pragmatically determined in Early Old Swedish. Within the framework of Principles and Parameters, a formalized description of this difference is given. It is assumed that the uninterpretable subject feature in the I-domain in Early Old Swedish does not carry EPP and therefore can be eliminated without visible movement, whereas this feature carries EPP in Modern Swedish and therefore must be removed by a visible movement of the subject to Spec, IP. The change from a pragmatically to a syntactically determined movement to Spec, IP is related to a change in frequency patterns, in turn triggered by the loss of OV word order in Swedish.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/43a647e9-7f7a-433d-8b1c-8b8ea8eb9c01</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Hakansson_1_upp.pdf">https://portal.research.lu.se/files/3064840/1032945.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3738463</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Språk- och litteraturcentrum, Lunds universitet</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>information structure</topic> <topic>word order</topic> <topic>null subjects</topic> <topic>referential subjects</topic> <topic>Old Swedish</topic> <topic>language variation</topic> <topic>diachronic syntax</topic> <topic>syntactic change</topic> <topic>verbal agreement</topic> <topic>quantitative analysis</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lundastudier i nordisk språkvetenskap.

The emergence of the category and its construction depends on a number of “truths” concerning children, related to historical and cultural processes in society. A main focus of the thesis is to investigate how legitimacy is established for the practice of defining deviance among preschoolers, and analyse the knowledge and rationalities that prevail in discursive practice. As part of this, the ways of defining children with special needs as a group are clarified, as well as the administrative procedures for handling their cases throughout the organisation. The study combines two strands within discourse analysis: “classical” discourse analysis with origins in Foucaults work and critical disourse analysis (CDA). The concept governmentality was used to make an analytical matrix, adapted to prescool practices. Data has been collected in a disadvantaged district belonging to the conurbation of a Swedish major city. Empirical material includes recording of an administrative meeting, application documents, interviews and national policy documents. The study shows that the categorisation have different effects and functions in different contexts. &lt;br/&gt;&lt;br/&gt;Implemental perspective: The practice of development evaluation of preschoolers has increased the written documentation, often based on techniques originating in compulsory school. These techniques are frequently ill adapted to the curriculum of the Swedish preschool, which emphasise the competent child and clearly encourages the child`s agency in preschool activities. Evaluation techniques also play the role of an incentive driving towards increasing individualisation. Educators tend to distance themselves from generalising concepts, and often assume a relational standpoint to defining deviance in children, but adapt to techniques that require a more individually based practice, which places the problems with the child. When parents consent to submit application documents, power is transformed to a range of professional actors, and a client-expert relationship is established. &lt;br/&gt;&lt;br/&gt;Administrative perspective: On the management level, the child primarily is subject to an economical rationality, and is expected to fit into existing preschool activities. The empirical material of this thesis does not display the inclusive perspective which occupies such a prominent position in special education discussions concerning compulsory school. The administrative conversation observed in the study was characterised by a quantitative approach, concerning resources for children who are considered deviant. Discussions at the meeting did not concern any aspect of the quality of the support offered, and the relationship between children and educators was reduced to a number of resouce hours per child. &lt;br/&gt;&lt;br/&gt;Societal (professional) perspectives: In an analysis of how resources for children with special needs are allocated in the city district, results will depend on which type of knowledge and rationalities are judged to be legitimate. Children who received a diagnosis delivered by a physician, or who are in the course of being investigated at the habilitation centre, obtain the largest support measures. A pattern supported by national policy documents, who constitute a steering mechanism towards implementation in educational establishments.&lt;br/&gt;Development evaluations in preschool can be seen as a step in Foucaults term “psycomplex”, where psychology is manifested in the institutions dealing with preschool children and their activities. The close historical link between pedagogy and developmental psychology, combined with a general development in society towards giving the individual perspective a central position, may contribute to the dominance of psychiatric assesments in explaining deviance among preschoolers.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/becf00bd-9790-47e4-8b2f-59a9e65bca8b</url> </location> </relatedItem> <originInfo> <publisher>Holmbergs</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Assesment</topic> <topic>development evaluation</topic> <topic>deviance</topic> <topic>discourse analysis</topic> <topic>governmentality</topic> <topic>inclusion</topic> <topic>normality</topic> <topic>preschool</topic> <topic>preschool children</topic> <topic>special needs</topic> </subject> <subject authority="lup"> <topic>Pedagogy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Malmö Studies in Educational Sciences</title> </titleInfo> <identifier type="issn">1651-4513</identifier> <identifier type="isbn">978-91-97100-6-0</identifier> <identifier type="oldLupId">1295965</identifier> <part> <detail type="volume"> <number>44</number> </detail> <extent unit="pages"> <total>236</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-03-20T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>becf00bd-9790-47e4-8b2f-59a9e65bca8b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:08+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:08+02:00</recordDateApproved> </recordInfo> </mods>

It also evaluated if their T1D and T2D-related genes differed from Swedish patients and whether this genetic heritage determined the types and existence of islet autoantibodies at time of diagnosis and affected the classification of diabetes. &lt;br/&gt;&lt;br&gt; A total of 3451 (55% males) newly diagnosed T1D patients (&amp;lt;18 y) were recruited from the Better Diabetes Diagnosis (BDD) study. We calculated the “patients/105/y” rate of confirmed T1D, which was 14 (95%CI: 13-15) among non-Swedes (8% of total) compared to 22 (95% CI: 21-23) for Swedes (66%). The rate for non-Swedes was at least 2 times higher than the mean incidence rates for countries of parents’ origins. Non-Swedes had predominately GAD65A (64%) in association with DQ2, which prevailed in the non-Swedes (34%, OR=1.5) compared to Swedes (15%). The Swedes had more multiple (&amp;gt;=2) autoantibodies and IA-2A in association with the dominant DQ8 and 2/8. The ZnT8-WA (38%) found less in non-Swedes compared to Swedes (50%), consistent with lower frequency in the non-Swedes (37%) of the SLC30A8 CT+TT than in Swedes (54%). The ZnT8-RA (57% and 58%, respectively) did not differ despite a higher frequency of CC (RR) genotypes in non-Swedes (63%) compared to Swedes (46%). In non-Swedes only, the prevailing DQ2/X (40%) compared to Swedes (14%) was negatively associated with ZnT8-WA (p=0.008) and ZnT8-QA (p=0.03) but not ZnT8-RA (p=0.26). Molecular simulation showed non-binding of the relevant ZnT8R peptide to DQ2 explaining in part the possible lack of tolerance to ZnT8-R by DQ2. The DQ8 and DQ6.4 had stronger binding epitopes outside the polymorphic site at amino acid position 325. The INS-SNP rs689 A/A genotype contributed T1D risk in non-Swedes (65%), though less than Swedes (72%). IAA were predicted by A/A (OR=3.5) but negatively associated with increasing age at diagnosis (OR=0.1) and HLA-DQ2 regardless of ethnic background (OR=0.6) explaining, in addition to INS T/T, the lower IAA in non-Swedes. In the &lt;br/&gt;&lt;br&gt; Swedes only, IAA were associated with DQ2/8 (40%) and 8/x (32%), which were also stronger predictors of IAA at a younger age than INS genotypes. Non-Swedes were further subdivided into non-Europeans (n=148, 63%) and European-descent (n=86, 37%). Non-European had less T1D risk genes (HLA DQ and PTPN22) and more T2D risk genes (SLC30A8 and FTO genes), therefore they were more prone to be autoantibody-negative (11% compared to 8% in Europeans and 6% in Swedes)and had less multiple autoantibodies (64%% compared to 81% in Europeans and 79% in Swedes).&lt;br/&gt;&lt;br&gt; Our data suggest that immigrants from low incidence countries (80% were born in Sweden), especially non-Europeans, are exposed to higher T1D in Sweden, because their genetic heritage affected by the Swedish environment. Non-European immigrants develop T1D in Sweden with lesser T1D-related genes but more T2D-related genes and less islet autoantibodies when compared to Europeans and native Swedes.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Syfte&lt;br/&gt;&lt;br&gt; Syftet med denna avhandling var att undersöka om barn födda i Sverige till invandrare (icke-Svenskar) hade en ökad risk för typ 1 diabetes (T1D) och om immunogenetiska markörer för T1D (HLA och icke-HLA genetiska faktorer samt ö-cellsantikroppar) skiljde sig från svenska T1D barn (Svenskar). Målsättningen var också att analysera ärftliga förutsättningar (T1D och T2D samt övervikt) hos icke-Svenskar i förhållande till klassificering av diabetes och i relation till förekomst av ö-cellsantikroppar vid diagnos av T1D. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Metoder&lt;br/&gt;&lt;br&gt; Totalt analyserades från Bättre Diabetes Diagnos (BDD) studien, 3686 (55% pojkar) patienter med barn- och ungdomsdiabetes (&amp;lt;18 år). Patienterna diagnosticerades under tiden maj 2005 - januari 2011. Nära 94% (n=34521) klassificerades med T1D och totalt hade 2964 av dessa T1D patienter också fullständiga uppgifter om autoimmuna markörer och födelseland. Patienterna delades upp efter födekseland för deras föräldrar och far- och morföräldrar i icke-Svenskar (7%), Svenskar (73%) och svenskar med blandad bakgrund (20%). I den senare gruppen utgjorde Svensk-Finska familjer den största gruppen. Svenskar med blandad bakgrund delades därför upp i Svensk-Finnar (6%) och Svenskar-Andra (14%). Födelseland samt andra demografiska uppgifter inklusive sjukdomar i familjen inhämtades med hjälp av frågeformulär som blev ifyllt i samband med att barnet insjuknade. Icke-Svenskar definierades som patienter födda till föräldrar och far- och morföräldrar som samtliga var födda i ett annat land. Svenskar definierades som patienter födda till föräldrar och far- och morföräldrar som samtliga var födda i Sverige. Två huvudgrupper kunde identifieras bland icke-Svenskar. Mellanöstern och Nordafrika (den sk. MENA gruppen, 58%) och sydöstra Europa (24%). Gruppen med icke-Svenskar delades därför upp i icke-Europeiska (n=148; 63%) och europeiska (n=86; 37%) invandrare. &lt;br/&gt;&lt;br&gt; Torkat blod på filterpapper (sk. Dried Blood Spots eller DBS) användes för att bestämma HLA-DQ genotyper. DNA extraherat från blodprov användes för genotypning av icke-HLA gener (SLC30A8, INS SNP rs689, PTPN22 och FTO). Blodprov togs inom tre dagar efter diagnos av diabetes. Serum analyserades för ö-cells autoantikroppar (IAA, GAD65A, IA-2A, ZnT8-RA, ZnT8-WA and ZnT8-QA). Molekylär modellering användes för att undersöka ZnT8 proteinets tre varianter på position 325 (R; W; and Q) för epitoper som skulle kunna binda till HLA-DQ2, HLA-DQ8, HLA-DQ2trans och HLA-DQ8trans heterodimerer. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Resultat: arbete I-IV&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete I&lt;br/&gt;&lt;br&gt; Incidensen av T1D var 14 (95%CI: 13-15) patienter/105/år bland icke-Svenskar (8% av alla patienter) jämfört med 22 (95% CI: 21-23) för svenskar (66%). Incidensen för icke-Svenskar var minst dubbelt så stor än medelincidensen i ursprungsländerna. DQ2, DQ8, eller bägge, fanns hos 89% av Svenskar och 82% av icke-Svenskar. DQ2 var vanligare hos icke-Svenskar (34%, OR=1.5 (95% CI: 1.0–2.0)) jämfört med Svenskar ( 15%; p&amp;lt;0.04). DQ8 var vanligast hos Svenskar (43%, p&amp;lt;0.0001) och Svensk-Finnar (53% p&amp;lt;0.0001) jämfört med icke-Svenskar (27%). GAD65A var vanligare hos icke-Svenskar (64%, p&amp;lt;0.02) och Svenskar (58%, p&amp;lt;0.04) jämfört med Svensk-Finnar (48%). GAD65A var associerade med DQ2 hos både icke-Svenskar (p&amp;lt;0.02) och Svenskar (p&amp;lt;0.0001). IA-2A var vanligast hos Svenskar (p&amp;lt;0.001) och var associerat med DQ8. Multipla (≥2) ö-cells autoantikroppar var vanligare hos Svenskar än icke-Svenskar (p&amp;lt;0.04) och var associerat med såväl DQ8 (p&amp;lt;0.0001) som DQ2/8 (p&amp;lt;0.001). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete II&lt;br/&gt;&lt;br&gt; Autoimmun (≥1 ö-cells autoantikropp) T1D undersöktes för ärftlig koppling till SLC30A8 och till ZnT8A. Icke-Svenskar (n=212) hade lägre frekvens av ZnT8-WA (38%) jämfört med Svenskar(50%) vilket förklarades av en lägre frekvens hos icke-Svenskar (37%) av SLC30A8 CT+TT (RW+WW) jämfört med Svenskar (54%). ZnT8-RA (respektive 57% and 58%) skiljde sig inte trots att CC (RR) genotypen hos icke-Svenskar (63%) var vanligare än hos Svenskar (46%). Skillnaden i ZnT8RA frekvens tycktes förklaras av HLA-DQ. Hos icke-Svenskar dominerade således DQ2/X (40%) jämfört med Svenskar (14%) och denna genotyp visade också en negativ association med både ZnT8WA och ZnT8QA men inte med ZnT8RA. Molekylär modellering visade att den relevanta ZnT8R epitopen sannolikt inte binder till en DQ2 heterodimer. Detta skulle kunna förklara varför immunologisk tolerans mot ZnT8R inte utvecklas hos DQ2 personer. Både DQ8 och DQ6.4 visade starka bindingsepitoper men dessa låg samtliga utanför position 325. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete III&lt;br/&gt;&lt;br&gt; Insulingenens (INS) bidrag till risk för T1D och eventuella interaktioner med HLA-DQ och IAA undersöktes hos icke-Svenskar och Svenskar. SNP rs689 användes som en genetisk markör för tidigare rapporterade INS-VNTR (A: class I och T: class III). INS-A/A bidrog till T1D risk hos både icke-Svenskar (65%) och Svenskar (72%) medan A/T var vanligare hos icke-Svenskar (32%) än Svenskar (24%). A/A var associerat med IAA hos Svenskar (37%) men inte hos icke-Svenskar (32%). T/T var dominant skyddande hos icke-Svenskar och negativt associerat till IAA hos Svenskar (15%). Risken för IAA var högst hos A/A (OR=3.5) och hos yngre patienter men IAA var negativt associerat med DQ2 hos samtliga grupper (OR=0.6). DQ2/8 (40%) och DQ8/x (32%) var associerade med IAA bara hos Svenskar och utgjorde en högre risk för IAA jämfört med INS genotypen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete IV&lt;br/&gt;&lt;br&gt; Icke-Svenskar delades in i icke-Europeer (n=148, 63%) och Europeer (n=86, 37%) för att undersöka genetiska förutsättningar för olika fenotyper av T1D. Icke-Europeer hade oftare DQ2 (46%) jämfört med Europeer (27%) och Svenskar (15%). Patienter som varken hade DQ2 eller DQ8 (DQx/x) var vanligare hos icke-Europeer (26%) jämfört med Europeer (23%) och Svenskar (14%). Icke-Europeer var därför oftare negativa för ö-cells autoantikroppar jämfört med Europeer och Svenskar (11%, 8% and 6%). De var också mindre benägna att ha multipla (≥2-6) ö-cells autoantikroppar (64%, 81% och 79%). Icke-Europeer hade fler T2D och obesitas-relaterade fenotyper. PTPN22 (R620W) risk genotyper (CT+TT) var ovanliga hos icke-Europeer (5%) jämfört med 14% hos Europeer och 35% hos Svenskar medan SLC30A8 CC genotypen var vanligare (72%, 50% och 46%). FTO AA risk genotypen var också vanligare hos icke-Europeer jämfört med Europeer och Svenskar (24%, 14% och17%). Icke-Europeer rapporterade oftare T1D än de andra två grupperna. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Konklusioner&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Etniskt ursprung påverkar den ärftliga risken för T1D hos barn som föds i Sverige till invandrare. Skillnader i ärftlig risk påverkar också skillnader i typ och antal av ö-cells autoantikroppar. Den relativt låga ärftliga risken för T1D (HLA-DQ samt icke-HLA gener) hos icke-Svenskar jämfört med Svenskar skulle därför framför allt påverkas av de ”diabetogena” omgivningsfaktorer som finns i Sverige. Denna inverkan skulle i sin tur påverkas av risk faktorer för T2D eller övervikt som fanns i större utsträckning hos icke-Svenskar. Fortsatta studier av mer homogena invandrargrupper skulle kunna identifiera dessa omgivningsfaktorer och ge en bättre förståelse av T1D naturalförlopp. Studier av invandare är fortsatt ett viktigt redskap att förstå T1D orsak och sjukdomsförlopp.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/bd23b7ea-8fb1-4141-863a-739662ed2dea</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="AJ_Delli_Thesis_2012.01.24_FINAL_Registered.pdf">https://portal.research.lu.se/files/3068274/4002751.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">22016447</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Diabetes</topic> <topic>Type 1 Diabetes</topic> <topic>Childhood</topic> <topic>Human Leukocyte Antigen (HLA)</topic> <topic>Islet autoantibodies</topic> <topic>Zinc Transporter 8 (ZnT8)</topic> <topic>Islet antigen (IA2-)</topic> <topic>Glutamic Acid Decarboxylase 65 (GAD65</topic> <topic>Insulin</topic> <topic>Migration.</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-76-5</identifier> <identifier type="oldLupId">4002691</identifier> <part> <detail type="volume"> <number>2013:14</number> </detail> <extent unit="pages"> <total>91</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-02-17T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>bd23b7ea-8fb1-4141-863a-739662ed2dea</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:15+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-03-17T05:51:49Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:15+02:00</recordDateApproved> </recordInfo> </mods>

Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. More sophisticated engine instrumentation with additional degrees of freedom has been added to the engine design to reduce emissions and fuel consumption. But, as engines become more complex, the task of calibration and control becomes more challenging. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis investigates approaches to utilize rich sensor information for multivariable engine control. Different combustion modes, and different combinations of sensors and actuators have been studied and evaluated experimentally on a full-scale six-cylinder heavy-duty engine. The work is divided into four areas: virtual emissions sensing, dynamic emissions models, optimal engine control, and control of sensitive combustion modes. The theme of the thesis is to show how feedback control based on rich sensor information can be exploited to improve the engine operation and reduce the off-line calibration effort.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The virtual sensing work presents a data-mining method for predicting exhaust emissions from cylinder pressure data. Principal component analysis was used to reduce the dimensionality of the high-resolution data, and a neural network model was trained to predict emissions on a cycle-to-cycle, cylinder-individual basis.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The work on dynamic models investigates how system identification can be used to find multivariable dynamic models from a set of engine actuators to a set of variables related to high-level engine specifications, namely emissions, work output, combustion phasing, and peak pressure derivative. It was shown how fairly simple Wiener models can capture the main dynamics of the engine at a grid of operating points. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; One of the identified multivariable models was used for optimal control of the engine. In contrast to most previous work in the field, integration of fuel- and gas-path control into a single framework was pursued. A model predictive controller was designed based on a cost function expressed in terms of high-level engine control objectives, and feedback was based on measured emissions as well as cylinder pressure data.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The final part of the thesis presents work on two sensitive combustion modes, HCCI and dual-fuel operation. Here, feedback control is necessary to achieve robust operation. For both types of combustion, it was shown how a combination of two actuators can be used to successfully control the combustion process.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; See attachment in related material</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8fd75c20-c3eb-4e98-a562-53a197bda47c</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis.pdf">https://portal.research.lu.se/files/3068636/2439874.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9047957</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Multivariable Control</topic> <topic>Model Predictive Control</topic> <topic>LQG Control</topic> <topic>Virtual Sensing</topic> <topic>System Identification</topic> <topic>Diesel engines</topic> <topic>HCCI engines</topic> <topic>Dual-Fuel Combustion</topic> <topic>Cylinder Pressure Sensors</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>PhD Thesis TFRT-1092</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">2439853</identifier> <part> <extent unit="pages"> <total>190</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popscienceMatematik i motorlabbet.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3068634/2439876.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-05-11T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>8fd75c20-c3eb-4e98-a562-53a197bda47c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:19+02:00</recordDateApproved> </recordInfo> </mods>

The Musical Dramaturgy of the Car Radio Opera &quot;Cleansing of the Soul through Fun and Games&quot;.&lt;br/&gt;&lt;br&gt; This thesis focuses on musical dramaturgy in operas with a story. I believe my own music is better when I write operas than instrumental music. The question is why? The aim of this thesis is to investigate the relationship between story and music and see how it affects the composing process. The point of departure of the study is the rhythm of duration (or continuous course) since story and music proceed side by side in time.&lt;br/&gt;&lt;br&gt; The artistic activity as such is made use of methodically to develop theories and tools. For this thesis I have written an opera specifically for the car radio and the opera is used to exemplify the discussion. Theoretically the genesis of this opera is understood as a creative act rather than one of causality or teleology. Beat analysis is a tool to uncover the interaction between story and music. Second-order melody gives&lt;br/&gt;&lt;br&gt; examples of formal thinking in rhythms of duration. The music can prolong any moment of the action in a drama. The aria, the most important element of opera brings out, when the action comes to a halt, a decisive statement of affect, which makes real presence possible. The composer has to indulge&lt;br/&gt;&lt;br&gt; in the timing of the rhythms of duration. In culminations, previously introduced music is combined resulting in a complex dramatic climax. The rhythmical continuity creates multi-layered patterns of waves that hold the piece together, even when the contrasts of the drama are reflected in the music. The twofold rhythm of duration in opera means that story and music implicate each other mutually, but only at specific beats. The articulation of contrasts in musical drama has influenced and developed my own personal, originally instrumental, concept of form.</abstract> <abstract lang="swe">Avhandlingen fokuserar på musikdramaturgi i opera som har en story. Jag tycker att min egen musik blir bättre när jag skriver opera än konsertverk, frågan är varför? Syftet är att undersöka förhållandet story och musik och hur det påverkar komponerandet. Förloppet är undersökningens utgångspunkt eftersom story och musik pågår parallellt i tiden. Den konstnärliga verksamheten tas metodiskt i anspråk för att utveckla teori och verktyg. Jag har för avhandlingen skrivit en opera speciellt för bilradio – den exemplifierar resonemangen. Teoretiskt förstås och förklaras hur denna opera uppstått ur en skapande handling. Steganalys är ett verktyg för att frilägga interaktionen mellan story och musik. Melodi av andra ordningen ger exempel på förloppsbaserat formtänkande. I ett dramatiskt flöde kan musiken när som helst förlänga ett moment i handlingen. Arian, operans viktigaste formtyp, framhäver avgörande affektiva situationer genom att handlingen helt stannar och absolut närvaro möjliggörs. Tajmingen av förloppen får tonsättaren hänge sig åt. I kulminationer kombineras redan presenterad musik till komplexa dramatiska förlopp. Musikens rytmiska kontinuitet upprättar mångskiktade svängningsmönster som håller samman verket även när dramats kontraster avspeglar sig i musiken. Operans dubbla förlopp innebär att story och musik implicerar varandra ömsesidigt, men bara vid bestämda punkter. Musikdramatikens kontrasttänkande har påverkat och utvecklat mitt ursprungligen instrumentala formtänkande.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/97c45ccc-47e2-4070-92d2-07abaa57417d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Operans_dubbla_tidsforlopp__digital_publ.pdf">https://portal.research.lu.se/files/3068885/1895825.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3019101</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Malmö Faculty of Fine and Performing Arts, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Opera</topic> <topic>musical dramaturgy</topic> <topic>duration</topic> <topic>story</topic> <topic>real presence</topic> <topic>aria</topic> <topic>affect</topic> <topic>music to action</topic> <topic>rhythmical continuity</topic> <topic>timing</topic> <topic>beat</topic> <topic>artistic research</topic> <topic>musikdramaturgi</topic> <topic>fortvaro</topic> <topic>absolut närvaro</topic> <topic>affekt</topic> <topic>musik till handling</topic> <topic>rytmisk kontinuitet</topic> <topic>tajming</topic> <topic>steg</topic> <topic>konstnärlig forskning</topic> <topic>förlopp</topic> </subject> <subject authority="lup"> <topic>Music</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Doctoral studies and research in fine and performing arts</title> </titleInfo> <identifier type="issn">1653-8617</identifier> <identifier type="isbn">978-91-979584-2-4</identifier> <identifier type="oldLupId">1895818</identifier> <part> <detail type="issue"> <number>7</number> </detail> <extent unit="pages"> <total>132</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-05-24T10:00:00+02:00</dateOther> <note type="additionalInfo">I den den publicerade avhandlingen finns libretto som appendix samt en CD med verket.

This system makes it possible to covertly manipulate the auditory feedback that participants receive of their own voice. First a word or utterance made by the participant is recorded, and later in the test this recording is inserted into their auditory feedback with precise timing, while the feedback of what they are actually saying is simultaneously blocked. This way, a situation is created where participants say one thing but hear themselves, in their own voice, saying something else. Two main studies were performed. In the first study, participants performed a Stroop test while single color-word utterances were covertly exchanged. When the timing was good, a majority of the voice exchanges were undetected, and in 85% of non-detected trials participants experienced the inserted word as self-produced. This demonstrates how there is a strong inferential component to the sense of agency for speech. Importantly, it shows how auditory feedback is actively used to specify the meaning of what the speaker is saying. In the second study, an argument for the so-called internal monitoring channel was investigated. It has been assumed that no speech errors that were interrupted quicker than 350 ms could have been detected with the auditory monitoring channel. Instead, it has been proposed that a prearticulatory internal channel is used. In this study, RSE was used to simulate speech errors. Participants had been told that their auditory feedback would sometimes be manipulated, and that they were supposed to interrupt their speech as quickly as possible when this happened. Results showed that more than 50% of the interruptions were made within 350 ms, and some were even made before 100 ms. This demonstrates that swift interruptions can be made based on auditory feedback alone. Consequently, it might not be necessary to postulate an internal monitoring channel to explain brief interruption times.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0caf67b1-8d01-4112-988d-3a54782bbf38</url> </location> </relatedItem> <originInfo> <publisher>Department of Philosophy, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Speech production</topic> <topic>self-monitoring</topic> <topic>voice manipulation</topic> <topic>self-comprehension</topic> <topic>sense of agency</topic> <topic>auditory feedback</topic> <topic>Real-time Speech Exchange</topic> <topic>internal monitoring</topic> </subject> <subject authority="lup"> <topic>Philosophy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Cognitive Studies</title> </titleInfo> <identifier type="issn">1101-8453</identifier> <identifier type="isbn">978-91-7623-043-5</identifier> <identifier type="oldLupId">4612342</identifier> <identifier type="other">Lund University Cognitive Studies 158</identifier> <part> <detail type="volume"> <number>158</number> </detail> <extent unit="pages"> <total>139</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-10-04T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>0caf67b1-8d01-4112-988d-3a54782bbf38</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-05-12T09:46:22Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:24+02:00</recordDateApproved> </recordInfo> </mods>

In order to achieve this; the widely used methodology for solving problems in porous media has been applied, the Lattice Boltzmann Method (LBM). LBM presents several advantages to solve problems where the microstructural architecture is complex. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The introductory part presents the scope of the thesis and the different parts include in the document. Different characteristics of the FCs are given, as well as the parts where the porous media are found within the FCs are presented. The mechanism of energy conversion for two selected kind of FCs is explained, and the simplified electrochemical reactions involved in such conversion are presented.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The second part of the thesis corresponds to the LBM explanation and the solution of several physical problems. The simulations are carried out at different Re in order to prove the ability of LBM for solving problems at different regimes, and to get knowledge about the boundary conditions implemented. The simulation results performed in this part are basically at macroscale. Momentum equation and energy equation form part of the results obtained using the LBM. All the simulations are validated with corresponding previous studies, which show a relatively high accuracy of the method.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Finally, the simulation results of the fluid behavior in porous media are presented. Both, randomly generated and a reconstructed porous domain from a real image are analyzed. Microstructure parameters such as porosity, gas-phase tortuosity and permeability are obtained after using the LBM. The results obtained are compared with previous studies, and the posibble future work is detailed in the last chapter.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/347a7645-ea68-4b97-ac31-9026b802dbca</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Licentiate_of_Philosophy_Mayken_Espinoza.pdf">https://portal.research.lu.se/files/3069534/8301747.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2910327</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Energy Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Porous media</topic> <topic>lattice Boltzmann method</topic> <topic>microscale</topic> <topic>Gas-phase tortuosity</topic> <topic>Porosity</topic> <topic>Fuel Cell</topic> </subject> <subject authority="lup"> <topic>Energy Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7623-593-5</identifier> <identifier type="oldLupId">7860280</identifier> <part> <extent unit="pages"> <total>49</total> </extent> </part> </relatedItem> <recordInfo> <recordIdentifier>347a7645-ea68-4b97-ac31-9026b802dbca</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:30+02:00</recordDateApproved> </recordInfo> </mods>

In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. There are several architectures for implementing an ADC, but in the last decade, continuous-time Delta-Sigma modulators (CT DSMs) have become popular due to their potential of achieving low power consumption and the inherent anti-alias filtering. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis investigates different implementations of CT DSMs intended for an ultra-low-power (ULP) receiver operating in the 2.45 GHz ISM band. The main focus is on power saving techniques and jitter insensitive solutions. Papers I and II present a CT DSM with dual switched-capacitor-resistor (DSCR) feedback used in the first DAC. This technique has been developed for the purpose of reducing the jitter sensitivity of the CT DSM while keeping the DAC peak current lower than for conventional SCR feedback. A lower peak current translates into more relaxed slew-rate requirements on the first operational amplifier and thereby less power consumption. Papers III and IV present a low power 2nd-order CT DSM with one operational amplifier. The main objective was to reduce the power consumption of the usually more critical analog part while still achieving a 2nd-order noise shaping. The thesis also examines the possibility of using a successive approximation register (SAR) quantizer instead of the commonly used flash quantizer to reduce the power consumption of the digital part as well.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Små, trådlösa och portabla apparater utgör idag en stor del av vår uppkopplade värld. Under det senaste decenniet har dock flera teknologiska framsteg lett mot en utveckling där allt från maskiner till kläder kommunicerar med varandra. Detta brukar kallas för &quot;sakernas internet&quot; och uppskattas involvera 50 miljarder enheter år 2020. Genom att förse dessa enheter med små och smarta sensorer är det möjligt att känna av omgivningen och samla in olika former av data. Det finns många potentiella applikationer där detta är av intresse t.ex. medicinska implantat, spelkontroller, smarta hus och industriell övervakning. Inom medicinska tillämpningar har sensornätverk redan använts för att hålla reda på patientens tillstånd och olika kroppsvärden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En av de största utmaningarna med sensornätverk är effektförbrukningen som bestämmer hur länge batteriet för en sensor kommer att räcka. Det är viktigt att batteritiden är så lång som möjligt eftersom sensorerna kan vara placerade på ställen som är svåra och farliga att komma åt. Energin från batteriet som sensorn har är det enda energin som den kommer få under dess livslängd. Eftersom batteritekniken går sakta framåt, är det viktigt att utveckla effektiva elektroniska kretsar och algoritmer som minimerar effekten som dras från batteriet. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En sensor kräver i slutändan digitala signaler för att uppnå den funktionalitet som anses viktig idag. Eftersom alla signaler i naturen är analoga, måste de omvandlas till digitala signaler. Detta är en uppgift för Analog-till-digital (A/D) omvandlaren som är en viktig del i det radiochip som sänder och tar emot signalerna i sensornätverket. Det kostar energi att omvandla analoga till digitala signaler vilket innebär att A/D omvandlaren är en kritisk komponent och ansvarar för en stor del av energiförbrukningen i ett radiochip. Det finns många typer av A/D omvandlare men under senare tid har Delta-Sigma modulatorn blivit populär inom många applikationer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den här avhandlingen undersöker flera kretslösningar med syftet att minska känsligheten för tidsfel, så kallad klockjitter, och sänka effektförbrukningen i Delta-Sigma modulatorn för en lågeffektsradio. Den första Delta-Sigma modulatorn som konstruerades använde en speciell lösning med dubbla exponentiella pulser för att minska känsligheten för klockjitter. Dessa pulser håller den maximala återkopplingsströmmen på en rimlig nivå och sänker därför strömkravet för den första förstärkaren. Den här tekniken har verifierats med simuleringar och mätningar på ett tillverkat chip. I den andra Delta-Sigma modulatorn undersöktes ett andra ordningens filter med bara en förstärkare för att minska effektförbrukningen i den analoga delen. Detta resulterade i en låg effektförbrukning medan den övriga prestandan uppfyllde kraven för lågeffektsradion. Den här tekniken har verifierats med simuleringar och mätningar på ett tillverkat chip. Slutligen användes en annan typ av A/D omvandlare s.k. successiv approximation A/D omvandlare som en del i den sistnämnda Delta-Sigma modulatorn för att ytterligare sänka effekten i den digitala delen. Konceptet har hittills verifierats med simuleringar. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det här arbetet har varit en del av ett större projekt som går ut på att konstruera en mottagarkedja för en lågeffektsradio. Kravet för den totala chipstorleken är 1 mm^2 och den maximala effektförbrukningen ska vara 1 mW.

The general aim of this thesis was to study the role and impact of Lp-PLA2 as cardiovascular (CV) risk marker in an epidemiologic perspective. Specific aims were to explore the cross-sectional association of Lp-PLA2 with traditional CV risk factors, to asses the genetic influence of PLA2G7 on plasma levels of Lp-PLA2, and to study the morbidity and mortality of cardiovascular disease (CVD) in relation to Lp-PLA2. Data from the population-based “Malmö Diet and Cancer” CV cohort (n=6103) was used. Information on Lp-PLA2 was available on 5393 subjects (41 % men) with a mean follow-up of 10.6 years. National and local registers were used to retrieve the incidence of coronary events (CE), ischemic stroke and mortality.&lt;br/&gt;&lt;br&gt; Lp-PLA2 (assessed as activity or mass) increases with age, is higher in males and in current smokers. Lp-PLA2 is strongly correlated with blood lipids (especially LDL-cholesterol), however, is weakly correlated to glucose and to the extent of carotid asymptomatic atherosclerosis (i.e. intima-media thickness and plaque).&lt;br/&gt;&lt;br&gt; Genetic variation at the PLA2G7 gene locus significantly influences plasma Lp-PLA2 activity and mass levels, in a position and sex-specific manner.&lt;br/&gt;&lt;br&gt; Both elevated levels of Lp-PLA2 activity and mass, respectively, are independent of blood lipids, hs-CRP and other traditional cardiovascular risk factors, associated with an increased risk for incident ischemic stroke. No similar independent relationship was observed between Lp-PLA2 and CE. &lt;br/&gt;&lt;br&gt; Lp-PLA2 activity, compared with mass, is more strongly correlated to all five components constituting the metabolic syndrome (MetS) and increased more linearly with number of MetS components. Elevated levels of Lp-PLA2 activity was related to increased risk for incident CVD regardless of MetS. High Lp-PLA2 levels and presence of MetS were additive predictors of those who experienced a CV event. &lt;br/&gt;&lt;br&gt; It is concluded that both genetic and life-style factors are related to elevated levels of Lp-PLA2. Lp-PLA2 is independently associated with increased CVD risk, in particular ischemic stroke. There is an additive effect of Lp-PLA2 to presence of MetS on incident CVD risk, which may identify an especially high risk individual.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/26360d18-bc11-47d5-9f31-4863dbf2707e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="PDF_Avhandling_kappan_080920.pdf">https://portal.research.lu.se/files/3073106/1243665.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">890538</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cardiovascular disease</topic> <topic>cohort study</topic> <topic>epidemiology</topic> <topic>Lp-PLA2</topic> <topic>PLA2G7 gene</topic> <topic>metabolic syndrome</topic> <topic>risk factor</topic> <topic>stroke</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-52-1</identifier> <identifier type="oldLupId">1243657</identifier> <part> <detail type="volume"> <number>2008:99</number> </detail> <extent unit="pages"> <total>136</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-25T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>26360d18-bc11-47d5-9f31-4863dbf2707e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:36+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:36+02:00</recordDateApproved> </recordInfo> </mods>

Few studies of CHD have been performed on women&lt;br/&gt;&lt;br&gt; or with a focus on cardiac risk factors in women’s lives. Results from studies of men&lt;br/&gt;&lt;br&gt; have been generalized to women, which may be inappropriate or even dangerous.&lt;br/&gt;&lt;br&gt; Aim: The overall aim of this thesis was to describe women’s experience of a&lt;br/&gt;&lt;br&gt; myocardial infarction and to explore and describe important factors associated with&lt;br/&gt;&lt;br&gt; this. Furthermore, to describe women’s daily life five years later and the long-term&lt;br/&gt;&lt;br&gt; follow-up resources in primary care.&lt;br/&gt;&lt;br&gt; Method: The first study (I) described women’s (n=19) symptoms and reasons for&lt;br/&gt;&lt;br&gt; delay in seeking medical care at the time of a first myocardial infarction. A content&lt;br/&gt;&lt;br&gt; Sanalysis method was used. The second study (II) looked at how women perceive&lt;br/&gt;&lt;br&gt; stress in their daily lives at the time of (n=20) and after (n=14) the MI. The third&lt;br/&gt;&lt;br&gt; study (III) examines how women cope with stress at the time of (n=20) and after&lt;br/&gt;&lt;br&gt; (n=14) an MI. In study four (IV) the women (n=12) were interviewed five years after&lt;br/&gt;&lt;br&gt; the MI. Studies II, III and IV used a phenomenographic method with contextual&lt;br/&gt;&lt;br&gt; analysis. Study five (V) describes the results of a questionnaire sent to primary health&lt;br/&gt;&lt;br&gt; care centres in Skåne, elucidating resources and cardiac rehabilitation possibilities.&lt;br/&gt;&lt;br&gt; Findings: The women had difficulties interpreting the symptoms or did not recognize&lt;br/&gt;&lt;br&gt; the symptoms at all until they experienced their first MI (I). They had problems&lt;br/&gt;&lt;br&gt; making the final decision to seek medical care. The women wanted support and help&lt;br/&gt;&lt;br&gt; from a family member or a friend. Some women found it difficult to call for&lt;br/&gt;&lt;br&gt; ambulance transportation and often first consulted the PHCC (I). Study II resulted in&lt;br/&gt;&lt;br&gt; two description categories: the women conceived the stress as a personal trait and as&lt;br/&gt;&lt;br&gt; a response to their immediate surroundings. The women had experienced being under&lt;br/&gt;&lt;br&gt; enormous pressure at the time of the MI, which they found stressful. Furthermore,&lt;br/&gt;&lt;br&gt; they had to assume a great deal of responsibility for their family and work. After the&lt;br/&gt;&lt;br&gt; MI the stress continued to increase. Study III resulted in three description categories&lt;br/&gt;&lt;br&gt; regarding the women’s coping strategies with stress at the time of and after the MI:&lt;br/&gt;&lt;br&gt; cogitative actions, social belonging and emotional diversion. The women became&lt;br/&gt;&lt;br&gt; aware that they needed to make plans for their needs and it was essential for them to&lt;br/&gt;&lt;br&gt; be confirmed. By talking to someone they trusted they received emotional support.&lt;br/&gt;&lt;br&gt; Avoidance was used because they did not take their cardiac events seriously and tried&lt;br/&gt;&lt;br&gt; just to resume their lives as if nothing had happened. Study IV showed that the&lt;br/&gt;&lt;br&gt; women changed their lifestyle immediately and some needed time for reflection&lt;br/&gt;&lt;br&gt; before they could make the prescribed lifestyle changes. The women found it&lt;br/&gt;&lt;br&gt; difficult to continue with all the changes. Even five years after the MI they still&lt;br/&gt;&lt;br&gt; needed support from health care professionals. A minority of the PHCCs (V) had&lt;br/&gt;&lt;br&gt; nurses with special education in coronary heart disease and cardiac rehabilitation, and&lt;br/&gt;&lt;br&gt; 5% of the PHCCs had nurses with a special position to take care of these patients. Of&lt;br/&gt;&lt;br&gt; all centres 76% had access to a physiotherapist whereas there were significantly more&lt;br/&gt;&lt;br&gt; 8&lt;br/&gt;&lt;br&gt; public PHCCs compared to private centres that had access to a physiotherapist. The&lt;br/&gt;&lt;br&gt; same relation was found regarding access to a dietician.&lt;br/&gt;&lt;br&gt; Conclusions and implications: The women had difficulties interpreting the symptoms&lt;br/&gt;&lt;br&gt; or did not recognize the symptoms at all until they experienced their first MI. For&lt;br/&gt;&lt;br&gt; women it is important to recognize the role of stress as an essential risk factor for MI.&lt;br/&gt;&lt;br&gt; The women described how they felt stress over a long period and how it affected&lt;br/&gt;&lt;br&gt; them. They mentioned different strategies to cope with stress in their personal and&lt;br/&gt;&lt;br&gt; professional lives related to MI. Even five years after the MI, that event had a&lt;br/&gt;&lt;br&gt; significant impact on the women An understanding of this phenomenon can assist&lt;br/&gt;&lt;br&gt; primary healthcare, coronary care and rehabilitation nurses in supporting women, as&lt;br/&gt;&lt;br&gt; well as their partners, to adapt their daily lives both before and after an MI. This&lt;br/&gt;&lt;br&gt; thesis points out that patients suffering an MI need long-term support. Well-educated&lt;br/&gt;&lt;br&gt; staff with adequate resources in primary health care can be of great importance.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Hjärt- och kärlsjukdomar är idag den vanligaste dödsorsaken i stora delar av världen&lt;br/&gt;&lt;br&gt; för både män och kvinnor. I Sverige är hjärtinfarkt den vanligaste dödsorsaken för&lt;br/&gt;&lt;br&gt; kvinnor över 55 år och för män över 45 år. Det vill säga kvinnor drabbas cirka 10 år&lt;br/&gt;&lt;br&gt; senare. Tidigare forskning har baserats i huvudsak på män varvid forskning på&lt;br/&gt;&lt;br&gt; kvinnor med hjärt- och kärlsjukdomar har försummats.&lt;br/&gt;&lt;br&gt; Det finns ett flertal riskfaktorer för att utveckla en hjärtinfarkt. De vanligaste och&lt;br/&gt;&lt;br&gt; mest välkända riskfaktorerna är ärftlighet, diabetes, hypertoni, men även livsstilsfaktorer&lt;br/&gt;&lt;br&gt; som övervikt, bristande fysisk aktivitet, rökning och stress är bidragande&lt;br/&gt;&lt;br&gt; faktorer. De senaste decenniernas forskning har dessutom visat att även psykosociala&lt;br/&gt;&lt;br&gt; faktorer har betydelse för risken att drabbas av hjärtinfarkt. Hur dessa riskfaktorer&lt;br/&gt;&lt;br&gt; påverkar individen ser olika ut för män och kvinnor.&lt;br/&gt;&lt;br&gt; Kvinnors situation i samhället har förändrats. Kvinnor förvärvsarbetar i samma&lt;br/&gt;&lt;br&gt; omfattning som män i dagens svenska samhälle. Trots detta så ansvarar kvinnor&lt;br/&gt;&lt;br&gt; fortfarande i större omfattning för hemmet och familjen än männen. Studier visar att&lt;br/&gt;&lt;br&gt; kvinnors upplevelse av stress huvudsakligen kommer ifrån arbetet i hemmet än från&lt;br/&gt;&lt;br&gt; förvärvsarbetet. Inom omvårdnadsprofessionen är det av stor vikt att förebygga&lt;br/&gt;&lt;br&gt; riskfaktorer och att försöka få till stånd en livsstilsförändring för att förhindra hjärtoch&lt;br/&gt;&lt;br&gt; kärlsjukdomar. Människor som drabbas av hjärt- och kärlsjukdomar lever under&lt;br/&gt;&lt;br&gt; ett livshotande tillstånd och detta ger inte bara fysiska besvär utan också emotionell&lt;br/&gt;&lt;br&gt; påverkan. Hur detta påverkar individen kan bero på förmågan att hantera&lt;br/&gt;&lt;br&gt; stresstillstånd i det dagliga livet.&lt;br/&gt;&lt;br&gt; Det övergripande syftet i denna avhandling var att beskriva och undersöka kvinnors&lt;br/&gt;&lt;br&gt; erfarenhet av att drabbas av en hjärtinfarkt. I studie II, III och IV användes ett&lt;br/&gt;&lt;br&gt; strategiskt urval utifrån ålder, antal barn, utbildningsnivå och civil status. Intervjuer&lt;br/&gt;&lt;br&gt; genomfördes vid två tillfällen. Den första intervjun genomfördes på intensivvårdsavdelningen&lt;br/&gt;&lt;br&gt; på andra eller tredje dagen efter insjuknandet. Den andra intervjun på&lt;br/&gt;&lt;br&gt; samma kvinnor genomfördes efter fyra, sex eller tio månader efter insjuknandet. Vid&lt;br/&gt;&lt;br&gt; första intervjun deltog 20 kvinnor och vid andra 14 kvinnor. Studie IV genomfördes&lt;br/&gt;&lt;br&gt; fem år efter insjuknandet i hjärtinfarkt. Studie III, III och IV har en fenomenografisk&lt;br/&gt;&lt;br&gt; ansats som är en explorativ och beskrivande kvalitativ metod. Studie I genomfördes&lt;br/&gt;&lt;br&gt; på intensivvårdsavdelningen och har innehållsanalys som metod. Studie V har en&lt;br/&gt;&lt;br&gt; kvantitaviv ansats med ett frågeformulär som utarbetades av författarna med&lt;br/&gt;&lt;br&gt; inspiration från andra studier; detta omfattade 26 frågor. Frågeformuläret skickades&lt;br/&gt;&lt;br&gt; med post till samtliga vårdcentraler i Skåne.&lt;br/&gt;&lt;br&gt; Första studien beskriver hur kvinnorna upplevde sina symtom i samband med&lt;br/&gt;&lt;br&gt; insjuknandet. Kvinnorna hade svårt att inse att symtomen hade koppling till&lt;br/&gt;&lt;br&gt; hjärtinfarkt. Det berodde på att symtomen inte var vad de upplevde som typiska för&lt;br/&gt;&lt;br&gt; hjärtinfarkt. Vidare hade de svårt att inse att de skulle kunna drabbas av hjärt- och&lt;br/&gt;&lt;br&gt; kärlsjukdom. Kvinnorna hade också upplevt en förändring i sitt hälsotillstånd en tid&lt;br/&gt;&lt;br&gt; 58&lt;br/&gt;&lt;br&gt; innan hjärtinfarkten; de upplevde trötthet och en viss obehagskänsla i bröstet. De&lt;br/&gt;&lt;br&gt; beskrev smärtan som tryck över bröstet och fastän det var svårt att hantera smärtan&lt;br/&gt;&lt;br&gt; ville kvinnorna stanna hemma så länge som möjligt och hoppades på att smärtan&lt;br/&gt;&lt;br&gt; skulle försvinna. Vidare beskrev kvinnorna hur de försökte med olika strategier för&lt;br/&gt;&lt;br&gt; att hantera smärtan istället för att uppsöka hälso- och sjukvården. De var i behov av&lt;br/&gt;&lt;br&gt; stöd och hjälp från anhöriga att ta beslutat att söka vård. De upplevde svårigheter att&lt;br/&gt;&lt;br&gt; kontakta ambulans och ville hellre själva ombesörja transport till sjukvården.&lt;br/&gt;&lt;br&gt; Den andra studien utmynnade i två beskrivningskategorier av hur kvinnorna&lt;br/&gt;&lt;br&gt; uppfattade stress före och efter hjärtinfarkten. Beskrivningskategori: A. Personliga&lt;br/&gt;&lt;br&gt; egenskaper och B. Påverkan från miljön: Före hjärtinfarkten uttryckte kvinnorna att&lt;br/&gt;&lt;br&gt; de levt under en långvarig press. De beskrev att stressen kom inifrån och att de&lt;br/&gt;&lt;br&gt; upplevde en rastlöshet på grund av att behöva ha ständig kontroll över tillvaron och&lt;br/&gt;&lt;br&gt; oron att inte räcka till. Kvinnorna uttryckte att de levt under stress en längre tid och&lt;br/&gt;&lt;br&gt; att detta berodde på en ständig och långvarig oro för en släkting eller en långvarig&lt;br/&gt;&lt;br&gt; konflikt. Vidare uttryckte kvinnorna att just denna ständiga oro och ångest var&lt;br/&gt;&lt;br&gt; påfrestande, vilket bidrog till att de aldrig kunde slappna av. De äldre kvinnorna&lt;br/&gt;&lt;br&gt; uttryckte att livet hade blivit meningslöst på grund av ensamhet och isolering.&lt;br/&gt;&lt;br&gt; Kvinnorna hade också andra kroniska sjukdomar såsom diabetes, reumatoid artrit och&lt;br/&gt;&lt;br&gt; de uppfattade att detta också var en utlösande faktor.&lt;br/&gt;&lt;br&gt; Före hjärtinfarkten uttryckte kvinnorna att de inte fick stöd från omgivningen i&lt;br/&gt;&lt;br&gt; samband med att de vårdade en släkting. De beskrev att de ensamma tog ansvar för&lt;br/&gt;&lt;br&gt; en sjuk anhörig och det uppfattades som stress. Kvinnorna uttryckte att de upplevt en&lt;br/&gt;&lt;br&gt; långvarig frustration beroende på påfrestande relationer, vilket beskrevs som en&lt;br/&gt;&lt;br&gt; långvarig stress. Kvinnorna uttryckte att de hade stort ansvar för familjen samtidigt&lt;br/&gt;&lt;br&gt; som de förvärvsarbetade. De beskrev att det var betungande att ta så mycket ansvar&lt;br/&gt;&lt;br&gt; och de hade också svårigheter att sätta gränser för vad de orkade med. Kvinnorna&lt;br/&gt;&lt;br&gt; uppfattade också att de tog ett stort ekonomiskt ansvar vilket resulterade i stress.&lt;br/&gt;&lt;br&gt; Efter hjärtinfarkten framkom ytterligare en uppfattning förutom de uppfattningar som&lt;br/&gt;&lt;br&gt; identifierades innan hjärtinfarkten. Det dagliga livet förändrades markant efter&lt;br/&gt;&lt;br&gt; hjärtinfarkten. Kvinnorna beskrev att de hade en ständig inre rastlöshet p.g.a. att de&lt;br/&gt;&lt;br&gt; inte hade styrkan att ha kontrollen över hemmet. Vidare framkom att de upplevde en&lt;br/&gt;&lt;br&gt; inre oro som var stressande, en oro över att ha varit allvarligt sjuk, men också en&lt;br/&gt;&lt;br&gt; uttalad oro över att få ytterligare en hjärtinfarkt. Detta bidrog till att kvinnorna ofta&lt;br/&gt;&lt;br&gt; uppsökte akutmottagning i tron om att de fått en ny hjärtinfarkt, men symtomen&lt;br/&gt;&lt;br&gt; berodde ofta på ångest och oro. Kvinnorna beskrev att de anhöriga hade en extremt&lt;br/&gt;&lt;br&gt; överbeskyddande attityd. Den överbeskyddande attityden ledde till stress och&lt;br/&gt;&lt;br&gt; aggressivitet hos kvinnorna och de uppfattade livet som meningslöst.&lt;br/&gt;&lt;br&gt; Livsstilsförändringar var nödvändigt efter hjärtinfarkt för att inte drabbas av en ny&lt;br/&gt;&lt;br&gt; hjärtinfarkt. En nödvändighet var att sluta röka. Detta påverkade kvinnorna psykiskt&lt;br/&gt;&lt;br&gt; eftersom rökning hade varit ett sätt att hantera sin stress. Kvinnorna var också fyllda&lt;br/&gt;&lt;br&gt; av funderingar kring sin sjukdom. De beskrev att de funderade över varför de hade&lt;br/&gt;&lt;br&gt; drabbats av hjärtinfarkt. Kvinnorna hade uppfattningen att endast äldre människor&lt;br/&gt;&lt;br&gt; 59&lt;br/&gt;&lt;br&gt; och framförallt män drabbas av hjärtinfarkt. De hade aldrig tänkt tanken att de själva&lt;br/&gt;&lt;br&gt; skulle kunna drabbas av en hjärtinfarkt.&lt;br/&gt;&lt;br&gt; Efter hjärtinfarkten uttryckte kvinnorna en stress över att de inte fick tillräckligt med&lt;br/&gt;&lt;br&gt; stöd och hjälp från kommunen. Det upplevde också en besvikelse kopplat till&lt;br/&gt;&lt;br&gt; rehabiliteringen. Kvinnorna var i varierande åldrar och hade skiftande behov vad det&lt;br/&gt;&lt;br&gt; gällde rehabilitering. Efter hjärtinfarkten upplevde kvinnorna stress och oro för hur&lt;br/&gt;&lt;br&gt; de skulle orka som tidigare, hur mycket de skulle orka arbeta samt en oro för&lt;br/&gt;&lt;br&gt; framtiden. Kvinnorna uttryckte också oro över sin ekonomi och sin arbetskapacitet.&lt;br/&gt;&lt;br&gt; Kvinnorna utvecklade olika sätt att hantera stressen i sitt dagliga liv både före och&lt;br/&gt;&lt;br&gt; efter hjärtinfarkten. Den andra studien utmynnade i tre beskrivningskategorier: A.&lt;br/&gt;&lt;br&gt; Kogitiva handlingar, B. Social tillhörighet samt C. Emotionell avkoppling. Via&lt;br/&gt;&lt;br&gt; reflektion fick de en bättre insikt över situationer som var stressfyllda. Detta&lt;br/&gt;&lt;br&gt; resulterade i att de planerade och prioriterade tillvaron på ett bättre sätt och kunde&lt;br/&gt;&lt;br&gt; undvika vissa stressituationer. De kvinnor som hade andra kroniska sjukdomar såsom&lt;br/&gt;&lt;br&gt; diabetes och reumatism försökte hantera detta genom att lära sig sina gränser och att&lt;br/&gt;&lt;br&gt; acceptera sin situation. Socialt stöd var ett värdefullt sätt att hantera stressen i det&lt;br/&gt;&lt;br&gt; dagliga livet såsom att tala med någon ex. en arbetskamrat eller släkting. Tala med&lt;br/&gt;&lt;br&gt; någon och speciellt med någon som var i samma situation gav kvinnorna nya krafter&lt;br/&gt;&lt;br&gt; att kunna gå vidare i livet. Kvinnorna hade också behov att bli bekräftade. De äldre&lt;br/&gt;&lt;br&gt; kvinnorna ville känna sig både behövda och bekräftade. När stressen i vardagslivet&lt;br/&gt;&lt;br&gt; blev för stor, var ett sätt för kvinnorna att bryta stressen att utnyttja sina egna&lt;br/&gt;&lt;br&gt; resurser. Denna förmåga skapade distans till tillvaron och gav en emotionell&lt;br/&gt;&lt;br&gt; avkoppling.&lt;br/&gt;&lt;br&gt; Efter hjärtinfarkten använde sig kvinnorna av kognitiva handlingar såsom reflektion,&lt;br/&gt;&lt;br&gt; planera och prioritera sin dagliga tillvaro. Kvinnorna hittade så småningom en ny&lt;br/&gt;&lt;br&gt; mening med livet och omvärderade sina liv samt anpassade sig till förändringen som&lt;br/&gt;&lt;br&gt; sjukdomen hade medfört. Det sociala stödet uppfattades av kvinnorna som viktigt.&lt;br/&gt;&lt;br&gt; Att prata med någon var betydelsefullt samt ett sätt att hantera stressen. Det som&lt;br/&gt;&lt;br&gt; kvinnorna ansåg som värdefullt var att träffa andra i samma situation, samt att höra&lt;br/&gt;&lt;br&gt; att andra erfarit samma oro, stress och ångest efter hjärtinfarkt. Bekräftelse från&lt;br/&gt;&lt;br&gt; hälso- och sjukvårdpersonal var viktigt såsom att få feedback från sjuksköterskorna i&lt;br/&gt;&lt;br&gt; rehabiliteringsteamet. Efter hemkomsten från sjukhuset var den första tiden kaotisk&lt;br/&gt;&lt;br&gt; och kvinnorna hade många funderingar kring hjärtinfarkten. De beskrev att det var&lt;br/&gt;&lt;br&gt; nödvändigt att komma ifrån alla dessa tankar kring hjärtinfarkten. Ett sätt var att göra&lt;br/&gt;&lt;br&gt; något annat och skingra tankarna såsom med trädgårdsskötsel, eller att läsa en bok.&lt;br/&gt;&lt;br&gt; Det var också svårt att ta till sig att de hade drabbats av en allvarlig sjukdom.&lt;br/&gt;&lt;br&gt; Kvinnorna använde sig inte sällan av förnekande.&lt;br/&gt;&lt;br&gt; Studie IV beskriver kvinnors upplevelser av hjärtinfarkt fem år senare. Det&lt;br/&gt;&lt;br&gt; resulterade i två huvudkategorier: A. Konsekvenser av en hjärtinfarkt och B. Att&lt;br/&gt;&lt;br&gt; anpassa sig till en ny livssituation. Kvinnorna upplevde fortfarande att deras&lt;br/&gt;&lt;br&gt; livssituation var påverkade av att ha haft en hjärtinfarkt. Eftersom kvinnor oftast är&lt;br/&gt;&lt;br&gt; äldre när de drabbas av hjärtinfarkt var det vanligt med olika följdsjukdomar och&lt;br/&gt;&lt;br&gt; 60&lt;br/&gt;&lt;br&gt; detta påverkade deras livssituation. Vidare upplevde de att de fortfarande hade olika&lt;br/&gt;&lt;br&gt; problem med sin hälsa som var relaterat till sin hjärtinfarkt. De upplevde fortfarande&lt;br/&gt;&lt;br&gt; att tillvaron var skör och att det fanns en ständig oro för att få en hjärtinfarkt.&lt;br/&gt;&lt;br&gt; Kvinnorna uttryckte också att det var viktigt med fortsatt stöd från hälso- och&lt;br/&gt;&lt;br&gt; sjukvården.&lt;br/&gt;&lt;br&gt; Studie V visade på vilka resurser som primärvården kan erbjuda för hjärtinfarktpatienter.&lt;br/&gt;&lt;br&gt; Vad det gällde utbildning för sjuksköterskor inom området hjärt- och&lt;br/&gt;&lt;br&gt; kärlsjukdomar, hade 32 % någon form av utbildning. Vidare kunde vårdcentraler&lt;br/&gt;&lt;br&gt; inom regionen erbjuda större möjligheter för patienter att ha tillgång till sjukgymnast&lt;br/&gt;&lt;br&gt; och dietist i jämförelse med de privata vårdcentralerna. Merparten av vårdcentraler&lt;br/&gt;&lt;br&gt; kunde inte erbjuda socioekonomiskt stöd; det samma gällde samarbete med olika&lt;br/&gt;&lt;br&gt; frivillig organisationer.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar avhandlingen på betydelsen av att se kvinnors livssituation&lt;br/&gt;&lt;br&gt; som en helhet för att kunna bidra till att identifiera riskfaktorer och att sätta in&lt;br/&gt;&lt;br&gt; preventiva åtgärder på ett tidigt stadium. Avhandlingen speglar betydelsen av att&lt;br/&gt;&lt;br&gt; hantera stressituationerna både före och efter sjukdomen. Avhandlingen pekar också&lt;br/&gt;&lt;br&gt; på vikten av att utforma individuella rehabiliteringsprogram, samt att det bör finnas&lt;br/&gt;&lt;br&gt; riktade rehabiliteringsprogram inom primärvården. Att förstå hur olika patienter&lt;br/&gt;&lt;br&gt; hantera stressituationer i samband med en kronisk sjukdom är ett viktigt forskningsområde&lt;br/&gt;&lt;br&gt; inom omvårdnad som bör utvecklas ytterligare. En slutsats är att i&lt;br/&gt;&lt;br&gt; rehabiliteringsprogram bör det även ingå att utveckla patientens egen förmåga att&lt;br/&gt;&lt;br&gt; hantera stress. Det finns ett behov av ett fortsatt och långsiktigt stöd och uppföljning.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/47a8e905-c433-431f-909d-11bdb9bb64e5</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_20110330_1_.pdf">https://portal.research.lu.se/files/3073127/1896293.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">489319</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Cardiothoracic Surgery, Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>myocardial infarction</topic> <topic>women</topic> <topic>content analysis</topic> <topic>phenomenographicmethod</topic> <topic>stress</topic> <topic>coping</topic> <topic>rehabilitation</topic> <topic>primary health care</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Univeristy, Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-87-7</identifier> <identifier type="oldLupId">1896292</identifier> <part> <detail type="volume"> <number>2011:39</number> </detail> <extent unit="pages"> <total>140</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-05-10T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>47a8e905-c433-431f-909d-11bdb9bb64e5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:36+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:36+02:00</recordDateApproved> </recordInfo> </mods>

The first perspective focuses on the literary techniques and the importance these may have for the interpretation of the content of the novels. This first reading includes a summary of the reception of the works and reveals many aspects that have not been discovered in earlier studies. The second reading is a Freudian interpretation of the novels. It explores to what extent these novels reproduces the Oedipus complex understood as a conflict between father and son, normally attributed to Freud. According to this reading it seems as if the author have been using the so called Freudian conception of the Oedipus complex as a literary technique, and it seems likely that he has done so deliberately. The implication of this strategy is explored in the third reading. In this reading the novels are interpreted from a Lacanian perspective, which means that the Oedipus complex is understood as the false interpretation that the subject has of his or her own history. The Lacanian interpretation reveals a subjacent structure that repeats itself in every novel. This structure has the following form: an initial paradise-like situation is disturbed by the arrival of an intruder, which functions as a latent representation of the father. The intruder’s death or expulsion is followed by a frustrated attempt of return to the lost paradise. What prevents a return to the initial situation is the representation of the mother’s betrayal. This structure reveals a whish to kill the father, as in the second reading, but it also reveals hate towards the mother that is being held responsible for the disgrace of her son. It is her betrayal that expels the son from paradise and makes his return impossible. This structure reveals a profound whish to not have been born. The last step of the Lacanian interpretation explores the relationship between the different contents of the novels, i.e. between the different readings. According to a psychoanalytic interpretation it seems as if the second reading constitutes a kind of defence which complicates a penetration of the profounder aspects of the novels. If the critics attribute aspects of the novel that are deliberate to the unconscious content of the novels it is plausible that they unconsciously serve as part of the author’s mechanisms of defence. If this is the case it seems as if the critics have followed the path marked by the author and that he controls them. Freud and Lacan separate between latent and manifest content but in the psychoanalytic interpretation of the novels of Vargas Llosa it is necessary to separate the manifest content in apparent and deliberate content. If not, it is likely that one falls in the trap that possibly has been construed by the author and explores the deliberate content of the novels as if it was part of the unconscious content. From this perspective even the apparent content constitutes an obstacle for the penetration in the deeper aspects of the works. Authors from the same generation as Vargas Llosa, such as Gabriel García Márquez, Carlos Fuentes and Julio Cortázar, uses different strategies to conceal one content beneath another, it is likely to think that Vargas Llosa uses a similar strategy and that he deliberately conceals what he understands as a Oedipal conflict in all of his novels. At the same time this strategy can be seen as an eloquent example of the lacanian conception of the Oedipal complex, that is as the misinterpretation of the own history. According to the Lacanian interpretation Vargas Llosa writes to not have to confront himself with the really painful aspects of his own life, and he uses the novels to create an almost impenetrable defence.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/600151f6-5a47-4fc3-8db6-c3fbffd234da</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Omslag.pdf">https://portal.research.lu.se/files/3073761/1468203.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">127407</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling.pdf">https://portal.research.lu.se/files/3073763/1468204.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1796217</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">spa</languageTerm> </language> <subject> <topic>meta reading.</topic> <topic>literary analysis</topic> <topic>different readings</topic> <topic>Structural psychoanalysis</topic> <topic>Latin-American literature</topic> <topic>hermeneutics</topic> <topic>psychoanalytic literary criticism</topic> <topic>transference</topic> <topic>Mario Vargas Llosa</topic> <topic>Sigmund Freud</topic> <topic>Jacques Lacan</topic> <topic>Lacanian study</topic> <topic>literary psychoanalysis</topic> <topic>applied psychoanalysis</topic> <topic>Psychoanalysis</topic> <topic>literary interpretation</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Études Romanes de Lund</title> </titleInfo> <identifier type="issn">0347-0822</identifier> <identifier type="isbn">978-91-978017-1-3</identifier> <identifier type="oldLupId">1468185</identifier> <part> <detail type="volume"> <number>86</number> </detail> <extent unit="pages"> <total>436</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-09-29T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>600151f6-5a47-4fc3-8db6-c3fbffd234da</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:39+02:00</recordDateApproved> </recordInfo> </mods>

Our goal has been to devise a general framework to enable a clear separation of the properties of the propagation channel from the influence of the antennas at the same time as it provides a common ground for a joint characterization of their properties. For this we have taken help of two tools: 1) a solution to Maxwell&apos;s equations, i.e., a spherical vector wave (svw) multi-modal expansion of the electromagnetic field and 2) the scattering matrix representation of an antenna that provides a full description of all its properties as a transmitting, receiving or scattering device. These tools offer a natural characterization of the polarizational, directional, and spatial properties of multiple-input multiple-output (MIMO) antenna systems. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis we first show that under some assumptions the propagation channel and the antenna are equivalent. The equivalence is in the sense that the impact of the channel cross-polarization ratio (XPR) and the antenna effective cross-polarization discrimination (XPD) on the mean effective gain (MEG) of an antenna are symmetrical. We also find bounds on the MEG in a wireless channel. Then we provide closed form expressions for the covariance of the field multi-modes as a function of the Power Angle Spectrum (PAS) and the channel XPR. A new interpretation of the MEG of antennas in terms of field multi-modes is also provided where the maximum MEG is obtained by conjugate mode matching between the antennas and the channel. We also show the (intuitive) result that the optimum decorrelation of the antenna signals is obtained by the excitation of orthogonal spherical vector wave modes. The cross-correlation coefficient between signals at two antenna branches (ports) in the presence of spatially selective interference and additive white gaussian noise is also investigated showing that spatial interference can also be readily modeled in terms of the svw mode expansion. We further devise a correlation model for co- and cross-polarized field components and introduce the concept of mode-to-mode channel mapping, the M-matrix, between the receive and transmit antenna modes. The M-matrix maps the modes excited by the transmitting antenna to the modes exciting the receive antennas and vice versa. The covariance statistics of this M-matrix are expressed as a function of the double-directional power-angular spectrum (PAS) of co- and cross-polarized components of the electromagnetic field. We finally derive physical limitations on the interactions of antennas exciting TM or TE modes (but not both) and wireless propagation channels. Rather than maximizing antenna gain in a single direction we obtain physical limitations on the antenna gain pattern, which is directly translated to more condensed parameters, i.e. the instantaneous effective gain Gi and the mean effective gain Ge if instantaneous realizations or correlation statistics of the expansion coefficients of the electromagnetic field are known, respectively. The obtained limitations are on the maximum of Gi/Q and Ge/Q, which establish a trade-off between link gain and the antenna quality factor Q.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/657097a1-1c9b-4533-b35f-556d739543ff</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis.pdf">https://portal.research.lu.se/files/3073940/1300427.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2753704</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Electrical and Information Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>antenna-channel interactions</topic> <topic>wireless channels</topic> <topic>MIMO</topic> <topic>Antennas</topic> <topic>propagation</topic> <topic>spherical vector waves</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">1300426</identifier> <part> <extent unit="pages"> <total>196</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-03-18T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>657097a1-1c9b-4533-b35f-556d739543ff</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:42+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-12-09T10:56:03Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:42+02:00</recordDateApproved> </recordInfo> </mods>

In this thesis important clinical, haemodynamic and electrophysiological aspects of ASD in the adult are explored.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The diagnostic accuracy of magnetic resonance velocity mapping (MRvm)in calculating the pulmonary/systemic flow ratio (QP/QS)was assessed (I). The mean and maximal error by MRvm was 1±1% and ≤4% respectively in the whole range of different QP/QS and repeatability showed a difference of 1±5%. Interobserver variability was four times higher for radionuclide angiography than MRvm, 16% vs. 4%, demonstrating the superiority of MRvm.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Atrial electrophysiological properties before and 8±6 months after ASD closure were examined by means of high-resolution orthogonal P-wave signal-averaged ECG (II and III). P-wave duration was significantly longer in ASD patients than in controls and overall, it was not significantly affected by ASD closure. P-wave duration did not relate to echocardiographic atrial sizes, suggesting atrial conduction delay which seems more or less irreversible in middle-aged ASD patients.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The remodelling potential and its speed were investigated by repeated echocardiograms before and during the 1st year after ASD closure (IV). Right ventricular and right atrial sizes as well as the pulmonary pressure levels were markedly reduced after ASD closure and became normal in a majority of the patients. In contrast, the left atrial size did not change and remained abnormal in 44%. When changes occurred they came early.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Outcome of ASD closure was compared to medical management 6 and 30 years after the initial assessment (V). Closure of the defect was superior to medical management in terms of functional class, heart size and pulmonary pressure in the intermediate term. Early ASD closure also seemed beneficial in terms of late cardiovascular morbidity and mortality, in spite of a high frequency of late ASD closure, after the intermediate exam, in the medically managed group. In summary, the findings favour timely closure of the ASD if to reduce the risk of late mortality and morbidity.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/80478947-ed57-427b-af35-a71a47cdb230</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Secundum_ASD_in_the_adult_Clinical_haemodynamic_and_electrophysiological_aspects.pdf">https://portal.research.lu.se/files/3074077/1390928.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">672410</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Cardiology, Clinical sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>MRI</topic> <topic>clinical outcome</topic> <topic>atrial fibrillation</topic> <topic>Atrial septal defect</topic> <topic>atrial conduction</topic> <topic>remodelling.</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-36-3</identifier> <identifier type="oldLupId">1390924</identifier> <part> <detail type="volume"> <number>2009:48</number> </detail> <extent unit="pages"> <total>68</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-20T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>80478947-ed57-427b-af35-a71a47cdb230</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:44+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:44+02:00</recordDateApproved> </recordInfo> </mods>

In spite of surgical resection, combined radiation therapy and chemotherapy, the mean survival is less than 15 months following diagnosis. Using the established N29 and N32 animal models of glioma, shown to have many similarities with the human tumor, we are able to study and develop therapeutic strategies against GBM.&lt;br/&gt;&lt;br&gt; The tumor models were first characterized according to cancer-initiating capacity. It was established that both models concomitantly and homogenously express several immature and mature markers of neural origin. Furthermore, the glioma cells were highly clonogenic in vitro and showed a robust tumorigenicity in vivo.&lt;br/&gt;&lt;br&gt; Next multipotent mesenchymal stromal cells (MSCs) were compared to neural precursor cells (NPCs) in capacity of survival and migration following intratumoral grafting, which revealed that MSCs were superior to NPCs as potential vectors in tumor therapy. It was also concluded that MSCs do not migrate towards a pre-established tumor when grafted behind it or in contact with the corpus callosum. Neither do the MSCs proliferate following grafting, further confirming that MSCs are suitable as cellular vehicles.&lt;br/&gt;&lt;br&gt; MSCs derived from adult rat bone marrow are relatively easily isolated and cultured as well as able to be stably transduced to express a therapeutic gene/drug. When MSCs are grafted intratumorally following peripheral immunizations with IFNγ-secreting autologous irradiated tumor cells, a synergistic effect on anti-tumor immunity is noticed with a prolonged survival and an increased tumor infiltration of immune cells.&lt;br/&gt;&lt;br&gt; Rat MSCs were modified to produce the cytokine interleukin 7 (IL-7), a growth factor for immune cells. IL-7 secreting MSCs injected intratumorally resulted in a decreased tumor area compared to control. When combined with peripheral immunization the mean area of pre-established tumors was further decreased. The effect on tumor was coupled to an increase of tumor-infiltrating T cells. &lt;br/&gt;&lt;br&gt; In conclusion this thesis points to a synergistic effect of intratumorally located MSCs and peripheral immunotherapy with IFNγ-producing tumor cells. Hopefully this combination might be further developed into a clinically useful treatment strategy.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4381d540-b8ab-408e-be28-5921c91b8999</url> </location> </relatedItem> <originInfo> <publisher>Avd för neurokirurgi/Lunds Stamcellscentrum, Inst för kliniska vetenskaper, Lunds Universitet</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>mesenchymal stromal cells</topic> <topic>rat</topic> <topic>IFNγ</topic> <topic>IL-7</topic> <topic>immunotherapy</topic> <topic>glioma</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> <topic>Surgery</topic> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-35-1</identifier> <identifier type="oldLupId">1554112</identifier> <part> <detail type="volume"> <number>2010:21</number> </detail> <extent unit="pages"> <total>104</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-03-26T09:30:00+01:00</dateOther> <recordInfo> <recordIdentifier>4381d540-b8ab-408e-be28-5921c91b8999</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:50+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:50+02:00</recordDateApproved> </recordInfo> </mods>

I wondered how the patients managed sexuality and closeness when suffering from OSA and in particular how the Continuous Positive Airways Pressure (CPAP) treatment affected their sexuality and closeness. A review of the literature showed there was little published information concerning the impact of CPAP treatment on sexuality; why it was difficult to advise the patients on this matter and how to predict whether closeness to one&apos;s partner would be reduced or improved when treated with CPAP. Furthermore; in order to guide and inform a patient as to how CPAP treatment may affect sexuality you have to know about sexual function and dysfunction as well as the difference between women and men. The overall aim of this thesis was to study the impact of nocturnal CPAP treatment on sexuality and closeness in patients with obstructive sleep apnoea. Patients with a diagnosis of OSA were consecutively recruited. After recruitment; 308 men and 92 women were included and after one year 150 men and 44 women remained in the study. Data was collected by self-reported questionnaires; the Epworth Sleepiness Scale and the Life Satisfaction 11. The specific sexual questionnaires for women were the Female Sexual Function Index and the Female Sexual Distress Scale. Manifest Female Sexual Dysfunction is present when the respondent has both sexual difficulty and sexual distress. The specific sexual questionnaire for men was the Brief Sexual Function Inventory. Male. Satisfaction with Sexual Life (Li-Sat 11) and both general and functional aspects of sexuality (BSFI) were significantly improved after 1 year of CPAP treatment. Female. Manifest Female Sexual Dysfunction was significantly improved after one year of CPAP treatment; but no significant changes in isolated sexual difficulties or sexual distress were found. Daytime sleepiness (ESS) decreased significantly in both female and male patients after 1 year of CPAP treatment. Daytime sleepiness decreased significantly in both male and female; indicating a positive effect of CPAP treatment. Sexuality improved both in general and specific aspects in male patients and female patients had a decrease in sexual dysfunction. Many patients may be reluctant to use a treatment involving the use of a mask; a tube and machine every night for many years to come. However; one of the main findings is that CPAP treatment per se does not negatively affect family life or partner relationship. I consider this important information when initiating CPAP treatment.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1943eea5-e874-4523-baac-d4057b13d9a8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="ThesisMarian2012.pdf">https://portal.research.lu.se/files/3075884/3165793.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1976298</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Respiratory Medicine and Allergology, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>obstructive sleep apnoea</topic> <topic>CPAP</topic> <topic>sexual distress</topic> <topic>sexual difficulties</topic> <topic>sexual dys function</topic> <topic>female</topic> <topic>male</topic> <topic>life satisfaction</topic> <topic>closeness.</topic> </subject> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-55-5</identifier> <identifier type="oldLupId">3165789</identifier> <part> <detail type="volume"> <number>2012:92</number> </detail> <extent unit="pages"> <total>65</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-11-23T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>1943eea5-e874-4523-baac-d4057b13d9a8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:53+02:00</recordDateApproved> </recordInfo> </mods>

Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. Applications from both process automation, manufacturing, and robotics have been considered.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; More flexible languages and tools are needed to get a flexible production system. The graphical programming language Grafchart, based on the IEC 61131-3 standard language Sequential Function Charts (SFC), is considered with the aim to make both the language and its implementation more flexible. In particular, new constructs have been added to the Grafchart language and modern compiler techniques are evaluated for JGrafchart, a Grafchart implementation, with focus on an extensible language implementation. A first step toward real-time execution of Grafchart applications is also taken to make it possible to use Grafchart for hard real-time control. High execution rates often reveal concurrency issues and thus execution concurrency has also been investigated.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Access to more data from industrial devices and software can be used to optimize production. Architectures for factory integration have been considered as this is the foundation to connect all devices and thus address the challenge of integrating and utilizing devices and software. Service Oriented Architecture (SOA) is a flexible software design methodology widely used in IT systems and for business processes. SOA service orchestration is brought to industrial automation by integrating support for both Devices Profile for Web Services (DPWS) and OPC Unified Architecture (OPC UA) in JGrafchart. Looking further, SOA 2.0 is event driven and features extremely loose coupling between components. An architecture based on SOA 2.0 where it is easy to integrate any device or software, in particular legacy devices with limited knowledge and capabilities, has been developed with focus on service choreography in industrial manufacturing. Another step toward real-time execution of Grafchart applications is integrated support for the high performance communication protocol LabComm. Additionally, it is investigated how Grafchart can be connected to Functional Mock-up Interface (FMI) for co-simulation to further address the shorter time to market trend by introducing simulation support.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The PID controller is the most common controller for industrial automation. A PID implementation has been added to a Grafchart library and a flaw with the PID algorithm has been discovered. The problem occurs for PID controllers with a derivative part when the process value saturates. The derivative part then backs off which leads to undesired changes in the control signal. This issue has been analyzed and a solution to the problem is proposed.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7f7dc71d-d637-4c0d-8034-2ed38b80c500</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="phd_web.pdf">https://portal.research.lu.se/files/3076432/4698755.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">16051512</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Grafchart</topic> <topic>service oriented architecture</topic> <topic>event-driven architecture</topic> <topic>flexible production systems</topic> <topic>industry 4.0</topic> <topic>real-time</topic> <topic>FMI</topic> <topic>PID</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>PhD Thesis TFRT-1104</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="issn">0280-5316</identifier> <identifier type="isbn">978-91-7623-110-4</identifier> <identifier type="isbn">978-91-7623-111-1</identifier> <identifier type="oldLupId">4698754</identifier> <part> <extent unit="pages"> <total>155</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-14T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>7f7dc71d-d637-4c0d-8034-2ed38b80c500</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:56+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-23T08:52:38Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:56+02:00</recordDateApproved> </recordInfo> </mods>

The mechanisms of leukocyte recruitment are well characterized and comprise on the one hand a mechanical trapping of leukocytes in sinusoids, and on the other hand a multi-step process of leukocyte-endothelial cell interactions in postsinusoidal venules. This process is mediated by a balanced interplay of several adhesion molecules, which finally results in a firm adhesion of leukocytes to the endothelial wall and a subsequent leukocyte extravasation and migration into the surrounding tissue.&lt;br/&gt;&lt;br&gt; Rho-kinase is an effector enzyme of small Rho-GTPases which are ubiquitously expressed and mediate a variety of intracellular mechanisms. Most importantly, Rho-kinase is involved in the organization of the actin cytoskeleton and cell movement. Further, it is known to be involved in the regulation of innate immunity. Thus, we herein investigated the involvement of Rho-kinase in endotoxemic liver and lung injury in a model of systemic inflammatory reaction. Further, we investigated the potential effects of simvastatin on LPS-induced liver injury, knowing that HMG-CoA reductase substrates are required for Rho-kinase activation.&lt;br/&gt;&lt;br&gt; We found that Rho-kinase is centrally involved in the regulation of inflammatory responses in endotoxemic systemic inflammation-induced liver and lung injury. Further, Rho-kinase also mediates local inflammatory reaction in the lung. HMG-CoA reductase inhibition was further shown to effectively prevent endotoxemic liver injury. &lt;br/&gt;&lt;br&gt; Thus, we herein propose Rho-kinase as an attractive target for treatment and prevention of endotoxin-induced inflammatory organ injury.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1991f169-cb5c-49ee-b330-c2054f028e4f</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-43-2</identifier> <identifier type="oldLupId">3051046</identifier> <part> <detail type="volume"> <number>2012:80</number> </detail> <extent unit="pages"> <total>147</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-10-09T08:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>1991f169-cb5c-49ee-b330-c2054f028e4f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:57:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:57:58+02:00</recordDateApproved> </recordInfo> </mods>

Pluripotent Stem Cells (PSCs) have the potential to be a source for generating HSCs. The indefinite expansion capacity of PSCs, combined with the possibility of creating these cells from patient-specific material could, in principle, allow for the generation of patient-derived HSCs. Generation of HSCs from PSCs could dramatically improve the treatment of patients in the clinic, including the possible correction of genetically carried hematological diseases. Furthermore, successful generation of HSCs would provide a tool to better study the nature of hematological malignancies, and could be employed for the purpose of drug screening&lt;br/&gt;&lt;br&gt; With the ultimate goal of facilitating in vitro generation of functional HSCs from human PSCs, the studies included in this thesis explore potential key factors and mechanisms involved in the process of hematopoietic development.&lt;br/&gt;&lt;br&gt; In paper I we describe that control over the amount of retinoic acid during in vitro differentiation of human PSCs increase blood generation, allowing for more defined and efficient production of relevant cells.&lt;br/&gt;&lt;br&gt; In paper II we provide a molecular identification of Endothelial to Hematopoietic Transition (EHT), the conversion through which HSCs emerge from endothelial cells. This provides a foundation for further characterization of the cells undergoing this transition, and could potentially enable control over this process for the purpose of more efficient generation of hematopoietic cells from hemogenic endothelium.&lt;br/&gt;&lt;br&gt; In paper III we explore how cAMP intrinsically regulates the generation of HSC-like cells, and we demonstrate the importance of cAMP signaling in the emergence of HSCs. Modulating cAMP provides an additional approach to increase the generation, and potentially the function, of HSC-like cells from human PSCs.&lt;br/&gt;&lt;br&gt; In paper IV, we demonstrate that reactive oxygen species is increased due to in vitro culture, causing functional impairment of hematopoietic progenitors and HSC-like cells generated from human PSCs. This argues that we must revise our standardized culture methods, and that a more physiological oxygen concentration is likely to be a critical component for handling and generating HSCs outside of the body.&lt;br/&gt;&lt;br&gt; In summary, the papers included in this thesis focuses on understanding the development of human HSCs, with the ultimate goal of developing methods that would enable the generation of functional HSCs in the laboratory, potentially translating into improved treatments against a multitude of hematological malignancies.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Idag har patienter med blodcancer (leukemi) eller genetiskt betingade blodsjukdomar (sickelcellanemi etc.) begränsad tillgång till behandlingar som effektivt och riskfritt botar sjukdomstillståndet. Detta arbete inkluderar forskningsresultat ämnade att bidra till utveckling av konceptuellt nya behandlingsmetoder för olika typer av blodsjukdomar.&lt;br/&gt;&lt;br&gt; Ett fungerande blodsystem är nödvändigt för varje individs överlevnad. De röda blodkropparna (erytrocyterna) förser kroppen med syre från lungorna, och de vita blodkropparna (leukocyterna) utgör vårt immunförsvar mot infektionssjukdomar. Blodceller slits snabbt ut och för att ersätta dessa behöver kroppen varje dag tillverka cirka 1 biljon nya blodceller. Ansvarig för denna kontinuerliga nyproduktion av blodceller är en sällsynt typ av blodceller som kallas för Hematopoetiska stamceller (HSCs), även kallade blodstamceller. Blodstamceller återfinns i benmärgen där de stundtals genomgår celldelning. Vid celldelning kan en dottercell påbörja en mognadsprocess där, efter många nya celldelningar, ett stort antal av färdiga blodceller resulterar. Blodstamceller är därför centrala för att våra kroppar ska kunna förses med nya blodceller genom livet. Blodstamceller är dock väldigt känsliga och kan fallera om de utsätts för skadliga faktorer som olika kemiska substanser, eller radioaktiv strålning. Vid behandling av blodcancer används idag ofta sådana faktorer för att ta död på cancercellerna. Dessa behandlingar medför ofta att även kroppens friska blodstamceller förstörs, vilket kan resultera i blodsystemets kollaps och patientens avlidande om detta inte åtgärdas. Därför genomgår patienter som genomgått cancerdödande behandling ofta en transplantation där blodstamceller från en donator införs i patientens kropp. Om transplantationen lyckats återetablerar donatorns blodstamceller en kontinuerlig nyproduktion av blodceller vilket resulterar i patientens överlevnad. Men donatorbaserad transplantation av blodstamceller kan medföra komplikationer. Mängden blodstamceller som kan inhämtas från en villig donator kan vara begränsad vilket resulterar i en oönskat lång återhämtning för patienten. En donator måste även vara immunkompatibel med patienten (att deras immunförsvar har liknande karaktär) för att minimera risken att det nya immunförsvaret reagerar mot patientens egna vävnader. Ett sådant tillstånd där transplantatet angriper värden, på engelska Graft Versus Host Diesease (GVHD), är livsfarligt för patienten. Därför krävs en hög kompatibilitet mellan patient och donator vilket ytterligare begränsar antalet möjliga donatorer. Det finns därför ett stort behov av patientkompatibla blodstamceller för att kunna möjliggöra optimal och effektiv behandling mot olika blodsjukdomar. En möjlighet att förse detta behov är odling och produktion av blodstamceller i laboratoriet.&lt;br/&gt;&lt;br&gt; I början av den embryonala utvecklingen (strax efter äggets befruktning) finns en typ av stamceller som kan ge upphov till alla olika typer av celler och vävnader i den vuxna kroppen. Dessa stamceller kallas därför pluripotenta och kan, om de stimuleras på rätt sätt, odlas i laboratorium för att utvecklas till olika vuxna celltyper inklusive blod. Pluripotenta stamceller behöver inte nödvändigtvis erhållas från embryon. År 2007 lyckades ett japanskt laboratorium, lett av professor Shinya Yamanaka, med att framställa mänskliga pluripotenta stamceller från vuxna hudceller. Denna bedrift belönades med Nobelpriset i medicin år 2012, och innebar nya möjligheter att framställa pluripotenta stamceller från enskilda individer som till exempel patienter. Om det vore möjligt att framställa funktionsdugliga blodstamceller från pluripotenta stamceller skulle behandlingen av blodsjukdomar kunna förbättras avsevärt eftersom det teoretiskt sett vore möjligt att framställa obegränsade mängder av nya patientkompatibla blodstamceller.&lt;br/&gt;&lt;br&gt; Denna avhandling innehåller 4 olika forskningsstudier där det gemensamma målet är att utveckla en metod för att lyckas med att framställa mänskliga blodstamceller från pluripotenta stamceller.&lt;br/&gt;&lt;br&gt; I den första studien demonstrerar vi att Retinoinsyra, en metabolit av Vitamin A, har en negativ påverkan under utvecklandet av pluripotenta stamceller till blod. Genom att använda en kemisk substans vid namn (DEAB) för att blockera cellernas egen produktion av Retinoinsyra kan vi flerfaldigt förbättra framställningen av celler vilka liknar blodstamceller. Ökad förståelse hur regleringen av utvecklingsprocessen går till är viktigt för att specifikt och effektivt kunna framställa de celler som är av intresse.&lt;br/&gt;&lt;br&gt; I den andra studien undersöker vi i detalj hur de första blodstamcell-lika cellerna formas. Under utvecklingen uppstår de första blodstamcellerna från endotelceller som täcker blodkärlens insida. Denna process, där en icke-blodcell genomgår ett identitetsbyte till blod, kallas för Endotelisk till Hematopoetisk Övergång, på engelska Endothelial to Hematopoietic Transition (EHT), och detaljerad vetskap om hur denna process fungerar saknas. Genom att studera övergången från endotel till blodcell beskriver vi ett specifikt övergångstillstånd som sker centralt i denna process. Våra resultat låter oss för första gången identifiera och särskilja de celler som deltar i denna övergång, vilket kan komma väl tillhanda om vi bättre vill efterlikna den embryonala blodutvecklingen för att kunna framställa blodstamceller i laboratoriet.&lt;br/&gt;&lt;br&gt; I den tredje studien visar vi att utvecklingen av blodstamcell-lika celler är i kritiskt behov av Cykliskt adenosinmonofosfat (cAMP) vilket fungerar som en sekundär budbärare åt flera olika signalsubstanser. Genom att manipulera cellernas mängd av cAMP demonstrerar vi flerfaldigt ökad framställning av blodstamcell-lika celler. Våra resultat påvisar även att cAMP förmedlar sina positiva effekter genom ej hittills uppskattade signaleringsleder inom cellen. Dessa resultat ökar vår förståelse över vilka faktorer som krävs för effektiv framställning av blod.&lt;br/&gt;&lt;br&gt; I den fjärde studien demonstrerar vi att majoriteten av alla blodstamcell-lika celler har förhöjda nivåer av reaktiva syregrupper, på engelska Reactive Oxygen Species (ROS), vilket orsakar funktionsoduglighet. Vi påvisar att denna förhöjning av reaktiva syregrupper orsakas av flera olika processer vilka grundar sig i de metoder för cellodling som idag är generell praxis. Genom att använda samt kombinera fyra olika metoder för att minska mängden av reaktiva syregrupper kan vi för första gången effektivt framställa blodstamcell-lika celler med reducerade mängder av ROS. Dessa celler uppvisar kraftigt förbättrad kapacitet för tillväxt. Våra resultat argumenterar för att reaktiva syregrupper vilka resulterar från våra cellodlingsmetoder utgör ett allvarligt hinder, samt att en reducering sannolikt är en nödvändighet, för lyckad framställning av funktionsdugliga blodstamceller i laboratoriet.&lt;br/&gt;&lt;br&gt; Sammantaget presenteras i denna avhandling forskning inriktad på att förstå utvecklingsprocessen av blod, med syfte att möjliggöra framställning av blodstamceller från pluripotenta stamceller. Våra resultat ger ökad insikt i hur denna komplicerade process fungerar och det är vår förhoppning att dessa framsteg kan bidra till en framtida metod vilken möjliggör effektiv framställning av funktionella blodstamceller. Detta eftersom en sådan metod drastiskt skulle kunna förbättra behandlingen av patienter som lider av diverse blodsjukdomar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/257b7d4c-3e70-47d0-8564-a7c3f50252ac</url> </location> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine, Institution of Laboratory Medicine, Division of Molecular Medicine and Gene Therapy</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Hematopoietic stem cells</topic> <topic>pluripotent stem cells</topic> <topic>embryonic development.</topic> <topic>in vitro differentiation</topic> </subject> <subject authority="lup"> <topic>Cell Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-222-1</identifier> <identifier type="oldLupId">8230932</identifier> <part> <detail type="volume"> <number>2015:142</number> </detail> <extent unit="pages"> <total>62</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-12-17T14:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>257b7d4c-3e70-47d0-8564-a7c3f50252ac</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:58:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:58:00+02:00</recordDateApproved> </recordInfo> </mods>

The answer was described to be a Sense of Coherence (SOC). SOC is a global orientation which contributes to how flexible coping strategies are chosen. The SOC concept was operationalized in The Sense of Coherence Scale (SOC-29). The questionnaire address to what extent life is perceived as comprehensible, manageable, and meaningful.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The aim of the thesis is to contribute to an answer what is being measured with SOC-29. Longitudinal data has been collected (N= 764) from social work students and social workers over 4, 5, and 11 years. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Factor analysis shows that SOC-29 measures a global concept without subscales. SOC-29 is not stable over longer periods, more than one year. There is no difference in stability related to respondents being younger or older than 30 years on baseline. SOC-29 change significantly for students during their education. &lt;br/&gt;&lt;br&gt; SOC-29 at the start of education does not predict whether students will finish their bachelor’s degree. &lt;br/&gt;&lt;br&gt; SOC-29 does not relate to socioeconomic position, gender or age. Social workers who are married or registered partnership have significant stronger SOC-29 than those living together with a partner or being single. The SOC concept measured with SOC-29 seems not to be culturally independent. SOC-29 has been tested with related constructs. SOC-29 has mainly strong significant correlations with instruments measuring negative/positive affect, neuroticism, and quality of life. Stepwise multiple regression analysis were performed on data from students (n= 207). Instruments measuring distress and negative affect contribute to 50 % explained variance of SOC-29. Instruments measuring quality of live and personal accomplishment contribute to 47% of the explained variance of SOC-29 for social workers (n= 116). Emotional exhaustion, control, work climate, work demands, work load and social support, does not contribute.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; SOC-29 shows high reliability, but the instrument can be developed. The scale can be used to evaluate social work interventions and education. SOC-29 can in social work education serve to demonstrate how this kind of instruments might be tools in social work practice.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3c4bc093-7cc2-4b03-bc61-e1536c743c89</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Gassne_Avhandling_2008.pdf">https://portal.research.lu.se/files/3077144/1025856.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1099463</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lunds universitet, Socialhögskolan</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>social workers</topic> <topic>social work education</topic> <topic>resilience</topic> <topic>quality of life</topic> <topic>soc</topic> <topic>sense of coherence</topic> <topic>Salutogenesis</topic> </subject> <subject authority="lup"> <topic>Social Work</topic> </subject> <relatedItem type="host"> <titleInfo> <title>LUND DISSERTATIONS IN SOCIAL WORK</title> </titleInfo> <identifier type="issn">1650-3872</identifier> <identifier type="isbn">978-91-89064-37-7</identifier> <identifier type="oldLupId">1025835</identifier> <part> <detail type="volume"> <number>30</number> </detail> <extent unit="pages"> <total>261</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-03-01T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>3c4bc093-7cc2-4b03-bc61-e1536c743c89</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:58:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:58:06+02:00</recordDateApproved> </recordInfo> </mods>

The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. One promising application of non-thermal plasmas is to achieve plasma-assisted combustion, in which new reaction pathways can be generated to increase chemical reaction rates, as well as to improve combustion efficiency and reduce pollutant emission. Developing and applying optical diagnostic tools help one to understand the underlying mechanisms of non-thermal plasmas and plasma-assisted combustion.&lt;br/&gt;&lt;br&gt; A gliding arc discharge is a simple and low-cost technique to provide non-thermal plasmas at atmospheric pressure. The plasma column of gliding arc discharges can be ignited at the narrowest gap between two diverging electrodes by a high-voltage power supply, after which it moves along the electrodes by means of gas flow. In the thesis, optical diagnostics of a gliding arc discharge were carried out with the aim in particular of being able to better understand discharge characteristics involved. High-speed photography at an exposure time of a few microseconds was used to capture the instantaneous structure of the plasma columns, and to record the spatial and temporal evolution of the gliding arc discharge. The plasma column was found to experience short-cutting events and transitions between glow-type and spark-type discharge, as well as a cycle of ignition, extension and extinction. Ground-state OH is an important chemically reactive species that can be generated by gliding arc discharges in humid air. Planar laser-induced fluorescence (PLIF) measurements demonstrated that ground-state OH was distributed around the plasma column and that the thickness of the OH was much greater than that of the plasma column. Turbulent effects played an important role in determining the OH distribution and the dynamics of the gliding arc discharge. Three-dimensional (3D) particle tracking velocimetry (PTV) and 3D reconstructions of the plasma columns were performed, providing a more accurate 3D determination of the slip velocity and the length of the gliding arc discharge. The translational temperature of the gliding arc discharge was measured by planar laser-induced Rayleigh scattering, and the electron temperature was calculated using the measured reduced electric field strength. The rotational and vibrational temperatures were determined by comparing the experimental and simulated spectra. The results are able to contribute to the optimized operation of the gliding arc discharge for practical applications and to a better understanding of the mechanisms governing non-thermal plasmas at atmospheric pressure. &lt;br/&gt;&lt;br&gt; The effects of non-thermal plasmas on combustion were investigated experimentally using PLIF. Several plasma sources, such as gliding arc discharges, microwave discharges and products (O3) stemming from dielectric barrier discharges, were employed for stimulating premixed CH4/air flames. It was found that the gliding arc discharge was able to promote the formation of CH2O and OH in the flame. An increase in CH2O was observed by means of PLIF when a high-power-density turbulent low-swirl flame was provided with small amounts of O3. The microwave increased both the chemiluminescence of the high-power-density turbulent flame and the PLIF signals from the OH and CH2O. The distributions of the CH2O signals shifted to be closer to the burner nozzle, indicating an increase in flame speed for the turbulent flame as the O3 and the microwaves were applied to the flame.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Plasma består av fria elektroner, joner och neutrala partiklar och utgör det fjärde tillståndet av materia där de andra tre är fast-, flytande- och gasfas. Plasma är den vanligast förekommande tillståndet av materia i universum och uppskattas utgöra mer än 99% av universums totala massa. Naturligt förekommande plasma återfinner vi i blixtar, sol vinden, jonosfären och i solen men människan har även utnyttjat plasmats egenskaper i ett flertal uppfinningar såsom i lysrör och i TV-skärmar. Människans nyfikenheten och innovationsförmåga har därför lett till omfattande forskning kring plasmarelaterade fenomen och tillämpningar vilket resulterat i en rad viktiga uppfinningar samt en grundläggande förståelse för jordelivets existens. &lt;br/&gt;&lt;br&gt; Ett icke-termiskt plasma är en typ av plasma som karakteriseras av hög elektrontemperatur i relation till gasens temperatur. Dessa heta/snabba fria elektroner kollidera med omgivande molekyler och kan därmed skapa nya molekyler och atomer som har stor benägenhet att reagera med omgivande molekyler och på så sätt påverka miljösammansättningens kemi. Denna kemiska effekt vill man använda sig av i till exempel plasma-asisterad förbränning för att kunna styra och effektivisera förbränningen, vilket resulterar i minskade utsläpp av såväl växthusgaser som giftiga ämnen, ökad användningsflexibiliteten av existerande förbränningsanläggningar, samt minskning av förslitningsskador och driftsstop av förbränningsanläggningar. Det finns dock en rad oklarheter i forskningsområdet av plasma-assisterad förbränning, exempelvis vilken typ av plasmakälla som är bäst lämpad för plasma-assisterad förbränning samt vilka kemiska processer som kan och bör påverkas. I undersökningar av förlopp med höga spänningar, höga temperaturer samt aggressiv kemi är optisk diagnostik en kraftfull metod då man kan mäta temperaturfält, flödesdynamik samt ämnespecifika fördelningar på avstånd samt med minimal inverkan på mätmiljön.&lt;br/&gt;&lt;br&gt; I detta avhandlingsarbete tillämpas och utvecklas optisk diagnostik i syfte att förstå plasmarelaterade fenomen och tillämpningar. Den strörsta delen av arbetet har fokuserat på optiska studier av glidande urladdningsplasman. En glidande urladdning skapas i luften i det smalaste gapet mellan två divergerande elektroder om en tillräckligt hög spänning läggs över elektroderna. Genom att applicera ett gasflöde kan urladdningskanalen förlängas vilket också medför att plasmakolumnens kontaktpunkterna glider längs med elektroderna (och därav namnet glidande urladdning). Förlängningen av plasmakanalen pågår tills resistansen i plasmakanalen blir för stor och en ny kolumn av plasma antänds igen vid det kortaste elektrodavståndet och den gamla kanalen slutar därmed leda ström. Dessa dynamiska förlopp har studerats med höghastighetsfotografering för att förstå samspelet mellan gasflödet och plasmat. Vidare har ämnesspecifika studier gjorts med avbildande laserinducerade fluorescencemätningar av hydroxylradikaler och kväveoxid, som är två viktiga ämnen i plasmarelaterade tillämpningar. Laserbaserade temperaturmätningar har även visat att uppställningen för glidande urladdningar i Lund opererar i icketermisk jämvikt med sin omgivning, vilket gör uppställningen ideal för tillämpningar för påverkan av reaktiva gasflöden.&lt;br/&gt;&lt;br&gt; I studier av plasmats påverkan på förbränning har ett flera olika typer av plasmarelaterade verktyg använts såsom barriärurladdningar, glidande urladdningar, mikrovågor samt dielektriska barriärurladdningar och koronaurladdningar för produktion av ozon. Man har funnit att glidande urladdningar kan interagera med flamman och främja bildningen av formaldehyd och hydroxylradikaler i flamman. Dessutom har ökad formaldehydproduktion observerats då små mängder av ozon seedats in i flamman samt att mikrovågsstimulering av förbränningen ökar den kemiska aktiviteten i turbulenta flammor</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/58c37660-5529-4789-aabb-385fe4616681</url> </location> </relatedItem> <originInfo> <publisher>Lund Report on Combustion Physics</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>High-speed photography</topic> <topic>Laser diagnostics</topic> <topic>Planar laser-induced fluorescence</topic> <topic>Plasma-assisted combustion</topic> <topic>Non-thermal plasmas</topic> <topic>Gliding arc discharge</topic> <topic>Optical diagnostics</topic> <topic>Particle tracking velocimetry</topic> <topic>Fysicumarkivet A:2015:Zhu</topic> </subject> <subject authority="lup"> <topic>Fusion, Plasma and Space Physics</topic> <topic>Atom and Molecular Physics and Optics</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7623-463-1</identifier> <identifier type="oldLupId">7766773</identifier> <part> <extent unit="pages"> <total>107</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-09-18T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>58c37660-5529-4789-aabb-385fe4616681</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:58:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:58:19+02:00</recordDateApproved> </recordInfo> </mods>

This is a&lt;br/&gt;&lt;br&gt; laboursome and costly procedure. The aim of this thesis is to provide tools that can reduce the amount of manual&lt;br/&gt;&lt;br&gt; labour required by using automated video analytics. Two methods for creating for such tools are presented.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The first method is a probabilistic background foreground segmentation that for each block of pixels calculate the&lt;br/&gt;&lt;br&gt; probability that this block currently views the static background or some moving foreground object. This is done&lt;br/&gt;&lt;br&gt; by deriving the probability distribution of the normalised cross correlation in the background and the foreground&lt;br/&gt;&lt;br&gt; case respectively. The background distribution depends on the amount of structure in the block.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The second method is a multi-target tracker that uses the probabilistic background foreground segmentation to&lt;br/&gt;&lt;br&gt; produce the trajectories of all objects in the scene. It operates online but with a few seconds delay in order to&lt;br/&gt;&lt;br&gt; incorporate information from both past and future frames when deciding on the current state. This means that the&lt;br/&gt;&lt;br&gt; output is guaranteed to be consistent, i.e. no jumping between different hypothesis, and the respect constrains&lt;br/&gt;&lt;br&gt; placed on the system such as &quot;objects may not occupy the same space at the same time&quot; or &quot;objects may only&lt;br/&gt;&lt;br&gt; appear at the border of the image&quot;.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The methods have been tested both on synthetic and numerous sets of real data by implementing applications such&lt;br/&gt;&lt;br&gt; as people counting, loitering detection and traffic surveillance.

The aim of the study is also on research basis to try out concepts that denote and capture the figuration of music activity. &lt;br/&gt;&lt;br/&gt;The overall research question is as follows:&lt;br/&gt;•What characterizes music activities and their possible figuration in preschool practices?&lt;br/&gt;&lt;br/&gt;”Possible figuration” refers to an interwoven presentation, a didaktik concept that describes transforming the significance of music activity. A weave of empirical and theoretical threads of references includes the answers to the following three subqueries:&lt;br/&gt;&lt;br/&gt;•What appears to be the focused content of music activity?&lt;br/&gt;•How is music activity staged?&lt;br/&gt;•How do children, teachers and music (in itself) act in music activity?&lt;br/&gt;&lt;br/&gt;As a theoretical resource, variuos concepts are tried within the frame of music didactics (Nielsen, 2006), education theory (Klafki, 2005) and the theory of musicking (Small, 2008). In the music activity the music phenomenon is understood as an object (Reimer, 2003), as action (Elliott, 2005; Small, 1998), and as something that takes place between the subject and the object (Nielsen, 2006). These three aspects of music stand in relation to the abductive method of analysis: they are relevant in generating an informative analysis (Alvesson &amp;amp; Sköldberg, 2008) and to thereby show the complexity of music activity. &lt;br/&gt;&lt;br/&gt;The empirical material was generated by video observation one day a week for eight months at three anonymized preschools (in the study, called: Havsvågen, Solstrålen and Trädet) in southern Sweden. The observations generated 46 video excerpts depicting music activity. &lt;br/&gt;&lt;br/&gt;According to my interpretation of focused content of a music activity usually concerns learning in and with music rather than about and through music. The content of a music activity appears to be both linear, with tradition as the main selection criterion, and non-linear, i.e., spontaneous, explored, and improvised in the moment. Some basic elements of music are processed and the music activity seems to move between material and formal education theory. The teachers sometimes focus on music as an object and, sometimes on the children, but music activity in which the teachers focus on the interaction between music and children, in line with categorical theory, is less often observed; this makes music activity appear sporadic and fragmentary. &lt;br/&gt;&lt;br/&gt;Staging music activity partly concerns spatial staging, and partly concerns actions in relation to a reproductive or an exploratory/productive function. The activity is characterized by sitting in a circle. In music activity in which movement emphasized the sitting and the circle are dispersed. Staging music activity involves how the activity starts and ends, as well as how each constituent action of the activity starts. In the initiation of the music activity, spoken instructions dominate. The music can also be a start-up and a closer. The constituent actions of the music activity can be grouped into listening, singing, moving and playing instruments, which can be related to their functions as reproductive or as exploratory/productive. Singing is mostly reproductive in character, playing instruments is mostly exploratory/productive, and moving is equally reproductive and exploratory/productive.&lt;br/&gt;&lt;br/&gt;The third and last question addressed in the study concerns the actors in the music activity. To make actions visible I have traced the actors or, as I call them, players. The players, i.e., the children, teachers, and music, can be interpreted as taking different forms of action. They can be front-players, soloists taking the initiative and influencing the music activity through their actions. They can be fellow players who take part in the music activity, but follow through rather than chape the content. They can also be co-players who shape the music activity, transforming it into interaction. The last type of player is the antagonist, who creates dissonance between child-teacher, music-teacher or music-child. &lt;br/&gt;&lt;br/&gt;In the thesis research, the concept of musicship appears and is tested, being constructed as a resource for reflecting on music activity. The musicship concept, gradually came to play more noticeable and nuanced. Musicship, in which music is a link in an interwoven process, can in this context say something about what is happening in music activity as figuration. Musicship has three tracks that sometimes cross each other and sometimes merge. The concept is also affected by a more general view of what music is made to be and what teachers emphasize, such as the music itself, the child/process, or the interaction between child and music. These three tracks focus on the content, staging, and actions of the music activity. They invite critical and creative reflection on music activity in preschool settings and in music-related processes. The content track concerns learning in, about, with, and through music. The staging track concerns procedure, the process of the activity with its functions and consistuent actions. The action track concerns how not only the children and teachers are actors, but also the music. The concept of musicship concentrates on:&lt;br/&gt;•content as movement between the linear and non-linear direction, content as object, and content as direction in movement, unestablished content, and shifting goals;&lt;br/&gt;•staging in which the actions constituting the activity (e.g., singing, moving, and playing) vary and interact with its underlying reproductive or exploratory/productive function; and&lt;br/&gt;•action in movement in which children, teachers, and the music can act as different types of players: front-players, fellow players, co-players, and antagonists. &lt;br/&gt;&lt;br/&gt;Musicship can be seen as: something that opens up for critically and possibly also a creative relation to a music activity, based on process and constantly being recreated as a form of music-related configuration; the merging of freeing and directing relations within a network; and a concept moving between the actual and the possible, facilitating the analysis and understanding of music activity.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8fd77f8e-4681-43ed-b128-20fe1bd3734f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Ylva_inlaga_print_27_feb.pdf">https://portal.research.lu.se/files/3078418/4352960.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4503720</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Malmö högskola</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>actors</topic> <topic>content</topic> <topic>didactics</topic> <topic>early childhood education</topic> <topic>music education</topic> </subject> <subject authority="lup"> <topic>Pedagogy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Malmö Studies in Educational Sciences</title> </titleInfo> <identifier type="issn">1651-4513</identifier> <identifier type="isbn">978-91-86295-38-7</identifier> <identifier type="isbn">978-91-86295-39-4 (pdf)</identifier> <identifier type="oldLupId">4352928</identifier> <part> <detail type="volume"> <number>71</number> </detail> <extent unit="pages"> <total>272</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-04-03T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>8fd77f8e-4681-43ed-b128-20fe1bd3734f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:58:29+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:58:29+02:00</recordDateApproved> </recordInfo> </mods>

Breast cancer is one of the most frequent malignancies in women worldwide, and it is characterized by heterogeneous tumor biology, histological subtypes, variable prognosis and variable responsiveness to treatment. Breast tumors frequently harbor a vast amount of genetic alterations including point mutations, structural rearrangements, and gain or loss of genetic material. These genetic alterations are believed to be hallmarks of gene deregulation and genome instability. In breast cancer, patterns of DNA copy number alterations have been shown to be specific for subtypes of breast cancer. Furthermore, recurrent alterations can point towards genes important in breast cancer carcinogenesis and may disclose potentially novel therapeutic targets, as exemplified by the HER2 oncogene. In the current thesis, microarray platforms and data analysis algorithms have been developed for investigation of DNA copy number alterations in breast cancer. Microarray platforms based on comparative genomic hybridization (aCGH) were developed for both genome-wide and focused delineation of complex genomic aberrations in breast cancer cells. Findings from data analysis of breast cancer cells motivated further investigation of a crucial step in low-level aCGH data analysis, normalization, resulting in a normalization strategy specifically for aCGH data. These methods were combined to characterize genomic aberrations in breast tumors harboring amplification of the HER2 oncogene, pinpointing significant aberrations including both known and potentially novel therapeutic targets. Moreover, using a bottom-up discovery strategy, analysis of global gene expression profiles from 58 HER2-amplified tumors revealed three subgroups of HER2+ tumors with different clinical characteristics and outcomes. A HER2-derived prognostic predictor was constructed based on analysis of genes differentially expressed among the three subgroups. Validation of the predictor in independent breast cancer data sets proved the prognostic association in HER2-amplified breast cancer, as well as other clinically challenging breast cancer subgroups. Together, the results shed further light on the genomically complex and heterogeneous nature of HER2-amplified breast cancer that may have therapeutic implications.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bröstcancer är den vanligaste cancerformen bland kvinnor i Sverige. Mer än 7000 kvinnor insjuknar varje år i bröstcancer, och cirka 1500 dör i sjukdomen. Incidensen av bröstcancer har stigit kontinuerligt sedan 1970-talet, och man uppskattar att en av tio kvinnor i Sverige kommer att utveckla bröstcancer någon gång under sin livstid. Den relativa överlevnaden i sjukdomen har dock parallellt förbättrats, och idag är 10-års överlevnaden ca 80%. Intensivt forskningsarbete har uppdagat att bröstcancer är en synnerligen heterogen och komplex sjukdom, med stora skillnader i biologi, ärftlighet, prognos, och behandlingssvar. Bristen på pålitliga faktorer för att förutbestämma risk och behandlingssvar medför att en betydande andel bröstcancerpatienter idag sannolikt överbehandlas, medan andra får för lite eller fel behandling. Stora forskningsinsatser har gjorts för att bättre karakterisera bröstcancer genom studier av förändringar i arvsmassan (DNA) och förändringar i uttrycket av gener (RNA) i tumörvävnad. Ett av målen med dessa studier har varit att definiera nya undergrupper av bröstcancer med prognostisk och behandlingsprediktiv betydelse, vilket i förlängningen kan leda till mer individualiserad behandling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Denna avhandling består av fem delarbeten där det övergripande målet har varit att utveckla och använda microarray baserade verktyg för att undersöka mönstret av genomiska (DNA) och transkriptionella (RNA) förändringar i bröstcancer. Brösttumörer uppvisar ofta stora avvikelser i arvsmassan, i form av exempelvis förlust eller ökning av antalet kopior av enskilda gener eller hela kromosomer. Frekvent förekommande DNA avvikelser kan indikera gener som är av betydelse för tumörutveckling och som kan utgöra mål för nya riktade läkemedel. I de två första delarbetena utvecklades microarray baserade teknikplattformar för jämförelse av antalet genkopior i cancerceller och normala celler (array-Comparative Genomic Hybridization, aCGH). Med aCGH kan genomiska förändringar kartläggas i hög detalj över tiotusentals mätpunkter spridda över hela det mänskliga genomet. I delarbete ett utvecklades en aCGH plattform baserad på längre genomiska fragment i Bacterial Artificial Chromosome (BAC) kloner, för kartläggning av förändringar över hela genomet i brösttumörer. I delarbete två utvecklades en aCGH plattform baserad på mycket korta DNA fragment (60 baser). Målet med denna plattform var att kunna detektera mycket små genomiska avvikelser inom enskilda gener. Sådana avvikelser kan exempelvis hittas nedärvda i arvsmassan hos kvinnor med ökad risk för bröstcancer. I delarbete ett fann vi även att befintliga metoder för vissa delsteg i analysen av aCGH data fungerade sämre för tumörprov med många genomiska avvikelser. I delarbete tre utvecklades därför en förbättrad metod för normalisering av aCGH data.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den förvärvade kunskapen från de första tre delarbetena användes i delarbete fyra för att karakterisera genomiska förändringar i brösttumörer med amplifiering (många extra genkopior) av HER2 genen på kromosom 17. HER2 tillhör en familj av tillväxtfaktorreceptorer som återfinns i cellmembranet, och som har en intracellulär tyrosinkinasaktivitet. Cirka 10-25% av all primär bröstcancer uppvisar ett ökat antal kopior (amplifiering) av HER2 genen, och i slutet av 1980-talet beskrevs kopplingen mellan amplifiering av HER2 (HER2+) och dålig prognos. Fortsatt forskning har visat att orsaken till att patienter med HER2+ tumörer ofta har dålig prognos beror på att ökade protein nivåer av HER2 receptorn ger tumörcellen viktiga fördelar (ökad tillväxthastighet och rörlighet, minskad celldöd), vilket resulterar i mer aggressiva tumörer. Relativt kort därefter isolerades en antikropp som selektivt kunde binda till HER2 receptorn på cellytan och hämma dess tumörfrämjande egenskaper. Baserat på resultaten av flera stora kliniska studier har riktad antikroppsbehandling mot HER2 nu blivit klinisk rutin för bröstcancer patienter med HER2+ sjukdom. Trots det enorma fokus som riktats mot HER2+ bröstcancer, finns en bristande kunskap om andra genomiska förändringar i dessa tumörer. I delarbete fyra använde vi därför aCGH för att kartlägga genomiska förändringar i 200 HER2+ tumörer. Med hjälp av aCGH kunde vi med hög noggrannhet definiera den minsta amplifierade regionen som innefattade förutom HER2 även fem andra gener. Vidare fann vi att HER2+ tumörer uppvisade komplexa och heterogena genomiska profiler med bl.a. återkommande amplifieringar av andra genomiska regioner, olikt andra undergrupper av bröstcancer. Vi identifierade ett flertal sådana frekvent förändrade genomiska regioner i HER2+ brösttumörer, varav vissa var mer frekventa i olika undergrupper av HER2+ tumörer. Fynden i delarbete fyra understryker den heterogenitet av genomiska förändringar som finns i HER2+ tumörer jämfört med andra undergrupper av bröstcancer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Även om patienter med HER2+ sjukdom historiskt har betraktats ha en sämre prognos så utvecklar inte alla patienter metastaserande sjukdom. En betydande andel av HER2+ patienter uppvisar dessutom resistens, antingen från start eller under behandling, mot riktad antikroppsbehandling. Det finns därför ett stort värde i att förbättra stratifieringen av HER2+ patienter i olika riskgrupper. I delarbete fem användes en kombination av aCGH och microarray baserad analys av genyttrycket (RNA) i HER2+ tumörer för att söka efter nya undergrupper med möjlig klinisk betydelse. Via analys av genuttrycksmönstret i 58 tumörer identifierade vi tre undergrupper av HER2+ tumörer. Dessa tre grupper uppvisade olikheter i association till olika kliniska variabler, och dessutom skillnader i prognos. Speciellt en undergrupp hade en klart sämre prognos jämfört med de andra två. Skillnaden i prognos föranledde oss att (1) identifiera vilka gener som karakteriserade undergruppen med sämre prognos, och (2) skapa en genexpressions baserad prognostisk prediktor utifrån dessa gener. När vi validerade prediktorn i flera oberoende bröstcancer material fann vi att den kunde identifiera inte bara HER2+ patienter med sämre prognos, utan även bröstcancer patienter med sämre prognos i andra högriskgrupper oavsett HER2 status.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har delarbetena i denna avhandling visat på styrkan hos microarray baserade plattformar i att kartlägga stora som små avvikelser i arvsmassan, samt transkriptionell deregulering i brösttumörer. Sammantaget har detta bidragit till ökad kunskap om brösttumörer med amplifiering av HER2 genen, vilket kan komma att vara betydelsefullt för bättre prognostisering och selektion av HER2+ patienter för nya behandlingsalternativ.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/eb317ab4-bda5-4284-a2c7-84609fe105c7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_JohanStaaf_Spikning.pdf">https://portal.research.lu.se/files/3078464/1578928.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3901229</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Oncology, Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Survival</topic> <topic>Prognostic predictor</topic> <topic>Gene Expression</topic> <topic>ERBB2</topic> <topic>HER2</topic> <topic>Microarray</topic> <topic>Copy Number Analysis</topic> <topic>CGH</topic> <topic>aCGH</topic> <topic>Amplification</topic> <topic>Gene expression analysis</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-51-1</identifier> <identifier type="oldLupId">1578892</identifier> <part> <detail type="volume"> <number>2010:36</number> </detail> <extent unit="pages"> <total>174</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://jco.ascopubs.org/cgi/content/abstract/JCO.2009.22.8775v1</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www3.interscience.wiley.com/journal/117890466/abstract?CRETRY=1&amp;SRETRY=0</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2190775/?tool=pubmed</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www3.interscience.wiley.com/journal/114134394/abstract</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-04-15T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>eb317ab4-bda5-4284-a2c7-84609fe105c7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:58:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:58:30+02:00</recordDateApproved> </recordInfo> </mods>

The importance of early and appropriate treatment of sepsis and severe bacterial infections has been underlined by many and since sepsis is more prevalent and has a higher mortality rate than for instance acute myocardial infarction, there is a need for improvement.&lt;br/&gt;&lt;br&gt; The heparin-binding protein (HBP, azurocidin, CAP37) is a multifunctional neutrophil-derived protein. HBP has been shown to be a powerful inducer of vascular leakage. In this thesis we demonstrate that HBP could have a potential role as a new biomarker for severe infections. First, the levels of HBP in plasma were closely correlated to development of circulatory failure in sepsis. This could help improving early identification of patients in the emergency department in need of aggressive treatment. Furthermore, we found that serial HBP measurements in plasma might be useful in predicting outcome in critically ill intensive care unit patients. We also found HBP to be present in higher amount in the cerebrospinal fluid of patients with acute bacterial meningitis compared to non-bacterial meningitis. Finally, we demonstrated that activation of the contact-system and release of HBP is present in the inflamed skin in erysipelas, suggesting a pathophysiological role in this relatively prevalent condition.&lt;br/&gt;&lt;br&gt; In conclusion, this thesis provides some novel findings stressing the important role of HBP in severe infections, its potential usefulness as a new biomarker, and maybe a future target of treatment.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; De senaste årens forskning har visat hur betydelsefullt vårt medfödda immunförsvar, ”Innate immunity”, är för kroppens möjligheter att bekämpa infektioner. Paradoxalt nog är det när detta mycket potenta immunförsvar överreagerar som allvarliga komplikationer till infektioner inträffar, som exempelvis vid sepsis och hjärnhinneinflammation (meningit). &lt;br/&gt;&lt;br&gt; Heparin-bindande protein (HBP) är ett multifunktionellt protein som är lagrat i neutrofila vita blodkroppar. HBP har visats vara antimikrobiellt, aktivera monocyter och orsaka läckage av plasma genom blodkärlsväggen (endotelet). HBP frisätts redan när neutrofilen kommer i kontakt med endotelytan och inducerar kapillärt läckage vilket möjliggör att blodkropparna kan ta sig från blodbanan till infektionshärden i vävnaden. Bakterier kan orsaka frisättning av HBP genom aktivering av specifika receptorer på neutrofilen, varvid kärlväggen blir läckande vilket leder till kardinalfyndet vid svår sepsis; cirkulationspåverkan.&lt;br/&gt;&lt;br&gt; Kontaktsystemet är också en del av det medfödda immunförsvaret. Systemet reglerar koagulationen men har även en viktig roll i inflammationssvaret vid infektioner. En aktivering av kontaktsystemet leder bland annat till frisättning av bradykinin. Bradykinin är en potent proinflammatorisk peptid som orsakar feber, ödem, smärta och hypotension. Flera studier har visat att kontaktsystemet aktiveras vid allvarliga infektioner som t.ex. sepsis.&lt;br/&gt;&lt;br&gt; I Arbete I samlade vi plasmaprover från 233 patienter som insjuknat akut med feber. HBP-nivåer analyserades med en ELISA-metod och resultaten jämfördes med några andra etablerade sepsismarkörer. Resultatet visade tydligt att de 38 patienter som vid inkomsten hade en svår infektion med lågt blodtryck som tecken på cirkulationssvikt, hade klart förhöjda nivåer av HBP i plasma. Än viktigare var upptäckten att majoriteten av de patienter som vid inkomsten inte visade tecken till cirkulationspåverkan, men som de kommande 12 timmarna utvecklade cirkulationssvikt, hade ett högt HBP-värde. Ett högt HBP-värde kunde identifiera 87% av patienterna med risk för sepsis och cirkulationssvikt och utesluta denna risk hos 95% av patienter med mildare infektioner. HBP visade sig vara en bättre biomarkör för sepsis än procalcitonin, interleukin-6, laktat och CRP. En biomarkör som tidigt signalerar svår sepsis kan medföra snabbare insatt behandling och korrekt vårdnivå.&lt;br/&gt;&lt;br&gt; I Arbete II ville vi veta mer om hur HBP nivåerna förändras över tid hos svårt sjuka patienter som vårdas på intensivvårdsavdelning (IVA). Plasmaprover från 179 patienter som vårdats på IVA analyserades och resultaten jämfördes med andra parametrar som idag används för att bedöma patientens prognos.&lt;br/&gt;&lt;br&gt; Resultaten visade att HBP-nivåerna var förhöjda hos 87% av patienterna med septisk chock under första IVA-dygnet. Det visade sig att HBP-nivåerna normaliserades hos de flesta som överlevde, medan HBP ofta var förhöjt eller stigande hos de som avled på sjukhuset. HBP korrelerade med flera av de parametrar som idag används för att bedöma sjukdomens allvarlighetsgrad, men var något bättre på att diagnosticera sepsis och även på att förutsäga vilka patienter som hade dålig överlevnadsprognos. &lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar dessa två studier att HBP är frisatt i plasma hos patienter med sepsis och cirkulationspåverkan, d.v.s. det som brukar definieras som svår sepsis. Att mäta HBP i plasma kan vara till både diagnostisk och prognostisk nytta för patienter med sepsis. I teorin skulle blockering av HBP-frisättning kunna vara ett intressant alternativ för framtida sepsisbehandling. &lt;br/&gt;&lt;br&gt; I Arbete III ville vi undersöka om HBP är mätbart i ryggmärgsvätska (likvor) hos patienter med meningit och om HBP i så fall skulle kunna användas som en diagnostisk markör vid detta tillstånd. Vid bakteriell meningit aktiveras immunförsvaret och man får feber samt infiltration av bakterier och efterföljande vita blodkroppar in i centrala nervsystemet (CNS). Detta kan leda till en tilltagande hjärnsvullnad, där HBPs förmåga att inducera kapillär läckage skulle kunna ha en betydelse. &lt;br/&gt;&lt;br&gt; I denna studie analyserades HBP-nivån i likvor från 174 patienter. Resultatet visade att HBP-nivåerna oftast var förhöjda i likvor vid bakteriell meningit, medan patienter med virusmeningit hade samma HBP-nivåer som kontrollpatienterna utan CNS-infektion. HBP kunde bättre skilja mellan bakteriell och viral meningit än de andra undersökta traditionella markörerna. Tidig och rätt diagnostik av meningit är av största vikt för att minska komplikationer och mortalitet vid dessa infektioner. En biomarkör som tidigt och med stor precision kan diagnosticera bakteriell meningit kan vara viktig för att förbättra prognosen vid detta livshotande tillstånd.&lt;br/&gt;&lt;br&gt; I Arbete IV fann vi att kontaktsystemet aktiveras och HBP frisätts i den inflammerade vävnaden hos patienter med rosfeber (erysipelas). Vi använde två olika metoder och resultaten överensstämde med varandra. Vi kunde också påvisa att grupp-A streptokocker var den vanligaste orsaken till rosfeber. Denna bakterie har visats kunna aktivera kontaktsystemet på sin yta och orsaka HBP-frisättning. Bradykinin orsakar feber, smärta, rodnad och ödem vilket är symtom som karakteriserar rosfeber. Även HBP skulle kunna spela en roll i ödemutvecklingen och har även antibakteriell aktivitet. Hudinfektioner orsakar ett stort lidande och tar enorma sjukvårdsresurser i anspråk. Tidigt insatt ”riktad” antiinflammatorisk behandling tillsammans med adekvat penicillinbehandling skulle teoretiskt sett kunna förkorta sjukdomsförloppet och minska patientlidandet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/25108db0-cfbf-46d2-b21b-d2a1fc57219c</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Infectious Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-95-2</identifier> <identifier type="oldLupId">1897890</identifier> <part> <detail type="volume"> <number>2011:47</number> </detail> <extent unit="pages"> <total>138</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-05-13T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>25108db0-cfbf-46d2-b21b-d2a1fc57219c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:15+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:15+02:00</recordDateApproved> </recordInfo> </mods>

The general aim of the thesis was to investigate the consequences of cold sensitivity for daily life in patients with traumatic hand injuries and hand-arm vibration syndrome (HAVS). To obtain a richer and more comprehensive picture reflecting the aim, studies with a quantitative and a qualitative design were performed. Questionnaires comprising patients’ experience of cold sensitivity were translated into Swedish according to the cross-cultural adaptation process and content and construct validity, internal consistency and test-retest reliability were established. In addition, a cut-off for abnormal cold sensitivity was defined as a total score &amp;gt; 50 on the Cold Intolerance Symptom Severity (CISS) questionnaire based on a normal population. Patients with abnormal self-reported cold sensitivity were more seriously disabled and had a poorer health-related quality of life than patients with normal cold sensitivity. The engagement in occupations was limited because of cold induced symptoms despite access to relieving strategies. The consequences and adaptation in daily life meant a change of occupational patterns and performance, a struggle with self-image and a change in life roles. Factors associated with abnormal cold sensitivity after a hand injury were a larger number of repaired vessels and use of vascular grafts at reconstruction, presence of trauma to bones and a high HISS score, suggesting multifactorial causes of cold sensitivity. Behavioural treatment offered relief to a majority of patients with a traumatic hand injury in contrast to patients with HAVS. Patients with HAVS had in comparison to hand injured patients overall significantly more severe problems with cold sensitivity.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/90a4868c-9dc9-4e89-b46f-1fc348712ac6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Ingela_Carlsson.pdf">https://portal.research.lu.se/files/3091340/1552047.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">421519</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Behavioural treatment</topic> <topic>cold sensitivity</topic> <topic>Cold Intolerance Symptom Severity questionnaire</topic> <topic>cold intolerance</topic> <topic>Cold Sensitivity Severity scale</topic> <topic>hand injury</topic> <topic>health-related quality of life</topic> <topic>hand-arm vibration syndrome</topic> <topic>occupation</topic> <topic>Potential Work Exposure Scale</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-28-3</identifier> <identifier type="oldLupId">1551173</identifier> <part> <detail type="volume"> <number>2010:14</number> </detail> <extent unit="pages"> <total>138</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-03-12T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>90a4868c-9dc9-4e89-b46f-1fc348712ac6</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:24+02:00</recordDateApproved> </recordInfo> </mods>

Connections between chronic inflammation and cancer are proposed by the increased remodelling and proliferation that occurs, leading to enhanced survival and proliferation of malignant cells. Since galectins have been implicated in mechanisms of both chronic inflammation and cancer, we have investigated natural binding partners of galectins in healthy individuals and then continued with studying states of cancer and chronic inflammation. We identified galectin binding glycoproteins in sera from healthy individuals and found that galectins widely expressed in the body bind serum glycoproteins well, whereas galectins with a more tissue-specific distribution scarcely binds any serum glycoproteins. We then chose the widely expressed but intermediately binding galectin-1 to detect if levels of galectin-1-binding proteins are increased in sera of breast cancer patients. We found that galectin-1 binds approximately double the amount in breast cancer patients compared to healthy individuals. The increase was mainly caused by haptoglobin, probably due to both increased expression and changes of glycosylation. &lt;br/&gt;&lt;br&gt; To further investigate the inflammatory connection we identified galectin binding proteins from bronchoalveolar lavage of asthma patients and healthy individuals, additionally we compared the binding of galectin-3 and galectin-8 that are expressed in different sites of the lung. We found when functionally grouping the bound proteins that galectin-3 and -8 binding proteins had different profiles and that bound proteins of healthy and asthma patients differed.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/cd3a8ae4-b129-470d-961f-e0b9ed81006f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="avhandling_cederfur_g5.pdf">https://portal.research.lu.se/files/3094836/1148941.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">585389</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cancer</topic> <topic>glycoprotein</topic> <topic>asthma</topic> <topic>bronchoalveolar lavage</topic> <topic>galectin binding protein</topic> <topic>galectin ligand</topic> <topic>galectin</topic> <topic>serum</topic> </subject> <subject authority="lup"> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-21-7</identifier> <identifier type="oldLupId">1148923</identifier> <part> <detail type="volume"> <number>2008:68</number> </detail> <extent unit="pages"> <total>73</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://dx.doi.org/doi:10.1093/glycob/cwn015</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-31T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>cd3a8ae4-b129-470d-961f-e0b9ed81006f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:32+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:32+02:00</recordDateApproved> </recordInfo> </mods>

Common for the scenarios considered are severe resource constraints, uncertain and time-varying conditions and the goal of enabling flexibility in systems design rather than restricting it. A brief survey on reservation-based scheduling, an important enabling technology for this thesis, is provided and shows how modern day resource reservation techniques are derived from their real-time system and telecommunications theory roots. Techniques for modeling components of cyber-physical systems, including both&lt;br/&gt;&lt;br&gt; computational and physical resources, are presented. The cyclic component model, specifically designed to model common resource demanding components in smart phones, is introduced together with techniques for model parameter estimation.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The topic of competitive resource management, where the different parts of the system compete for resources, is discussed using a smart phone platform as motivating example. The cyclic component model is used to form a rate-based performance metric that results in a convex optimization problem. A specialized optimization algorithm for solving this problem efficiently online and with limited precision hardware&lt;br/&gt;&lt;br&gt; is introduced and evaluated through simulations. A feedback control scheme for distributing resources in cases where components&lt;br/&gt;&lt;br&gt; collaborate, i.e., where the performance metric is dependent on more than&lt;br/&gt;&lt;br&gt; one component, is detailed and examined in a scenario where the available resource is limited by the thermal dynamics of the CPU. The scheme is evaluated through simulation of a conversational video pipeline. The thermal model is validated on a mobile robot, where it is used as part of an adaptive resource manager. The problem of energy conservative distribution of content to a population of co-located mobile clients is used to motivate the chapter on cooperative resource&lt;br/&gt;&lt;br&gt; management, i.e., scenarios where the participants have individual but similar goals and can benefit from sharing their partial results so that all collaborators save cost.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The model for content trading is presented in synchronous and asynchronous formulations and performance is evaluated through both simulations and experimental results using a prototype implementation in an emulated environment.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/cf850e8f-91f4-4ab5-83e2-abe00b942b4a</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis.pdf">https://portal.research.lu.se/files/3094871/4437764.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8578898</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>resource management</topic> <topic>feedback</topic> <topic>real-time</topic> <topic>optimization</topic> <topic>peer-to-peer</topic> <topic>cyber-physical systems</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>PhD Thesis TFRT-1102</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="issn">0280-5316</identifier> <identifier type="isbn">978-91-7623-018-3</identifier> <identifier type="isbn">978-91-7623-019-0</identifier> <identifier type="oldLupId">4437762</identifier> <part> <extent unit="pages"> <total>165</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-09T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>cf850e8f-91f4-4ab5-83e2-abe00b942b4a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:33+02:00</recordDateApproved> </recordInfo> </mods>

Även om det finns flera olika metoder för att behandla eller bromsa cancerutveckling, krävs det nya terapier på grund av allvarliga biverkningar och otillfredsställande resultat med de nuvarande behandlingsmetoderna.&lt;br/&gt;&lt;br&gt; I avhandlingen har vi arbetat med en grupp substanser som kallas naftoxylosider. Dessa består av två delar, sockret xylos, även kallat träsocker, sammankopplat med naftalen. Forskning har visat att vissa naftoxylosider kan hämma tillväxt av cancerceller.&lt;br/&gt;&lt;br&gt; Naftoxylosider är feta molekyler som kan ta sig igenom det fettrika cellmembranet och därmed ta sig in i celler. När naftoxylosider tas upp av celler härmar de en i celler naturligt förekommande process, bildandet av långa ogrenade sockerkedjor som kallas glykosaminoglykaner (GAGs). Istället för att bygga GAG-kedjorna på ett protein som det i normala fall görs, så byggs sockerkedjorna på våra syntetiska naftoxylosider. &lt;br/&gt;&lt;br&gt; Under senare år har det framgått genom cellbiologiska studier att GAGs är mycket viktiga makromolekyler som påverkar cellens funktioner och egenskaper. GAGs har visat sig vara inblandade i tillväxt och delning av cancerceller och även påverka flera olika aspekter inom cancerbiologi. De aspekter som berörs är till exempel utveckling mot en mer aggressiv cancertyp och spridning av cancerceller till andra organ.&lt;br/&gt;&lt;br&gt; Vi har arbetat med ett stort antal olika naftoxylosider där antingen naftalen-delen eller xylos-delen har modifierats på ett flertal olika sätt. Vi har sedan undersökt substansernas förmåga att bilda GAG-kedjor och även deras förmåga att hämma celldelning. &lt;br/&gt;&lt;br&gt; Vi har med hjälp av flera olika in vitro (i cellkultur) studier kommit fram till att substansernas fettlösliga egenskaper är viktiga för de ska kunna ta sig in i cellen och därmed påverka bildandet av GAG-kedjor och hämning av celldelning (antiproliferativ effekt). Vi har även påvisat att små modifieringar inom xylosdelen i naftoxylosider hindrar deras förmåga att bilda GAG-kedjor och tar därmed bort deras antiproliferativa egenskaper.&lt;br/&gt;&lt;br&gt; Vissa naftoxylosider har tidigare utretts av gruppen och visats ha en förmåga att selektivt hämma tillväxt av cancerceller. Vi har därmed haft som mål att studera den molekylära verkningsmekanismen för den selektiva antiproliferativa effekten som uppvisats av substansen XylNapOH. Vi har märkt XylNapOH och dess inaktiva analog XylNap med radioaktivt väte för att kunna följa substanserna inuti cellerna. Genom olika in vitro och in vivo (studie utförd på möss) studier kunde vi påvisa att cancerceller som behandlats med den aktiva substansen XylNapOH bildar en viss typ av celldödande GAG-kedjor som kan tas upp av både cancerceller och friska celler. Vi tror att, runt en tumör där det finns många cancerceller, byggs det upp en hög koncentration av cellgiftet som dödar tumören. Vi lokaliserade även XylNapOH och dess bildade GAG-kedjor till cellkärnan där de initierade apoptos, programmerad celldöd. Vi har dessutom visat att XylNapOH-behandlade cancerceller hämmar acetylering av histon H3 i cellkärnan. Acetylering av histon H3 är viktigt för cellens tillväxt, celldelning och apoptos.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis, så har vi med resultaten från våra studier fått större insikt i den tumörhämmande effekten hos naftoxylosider och har därmed kommit ett steg längre på vägen mot utveckling av nya sockerbaserade cancerläkemedel.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2c4c3f60-477f-4242-9410-0fc055fa436a</url> </location> </relatedItem> <originInfo> <publisher>Glycobiology, Dept of Experimental Medical Science</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>glycosaminoglycan</topic> <topic>proteoglycan</topic> <topic>heparan sulfate</topic> <topic>xyloside</topic> <topic>naphthoxyloside</topic> <topic>histone H3 acetylation</topic> </subject> <subject authority="lup"> <topic>Medicinal Chemistry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-13-0</identifier> <identifier type="oldLupId">3633590</identifier> <part> <detail type="volume"> <number>2013:43</number> </detail> <extent unit="pages"> <total>94</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-05-14T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>2c4c3f60-477f-4242-9410-0fc055fa436a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:33+02:00</recordDateApproved> </recordInfo> </mods>

While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. The time overhead is particularly important for a group of computer systems referred to as real-time systems (RTSs) where correct operation is defined as producing the correct result of a computation while satisfying given time constraints (deadlines). Depending on the consequences when the deadlines are violated, RTSs are classified into soft and hard RTSs. While violating deadlines in soft RTSs usually results in some performance degradation, violating deadlines in hard RTSs results in catastrophic consequences. To determine if deadlines are met, RTSs are analyzed with respect to average execution time (AET) and worst case execution time (WCET), where AET is used for soft RTSs, and WCET is used for hard RTSs. When fault tolerance is employed in both soft and hard RTSs, the time overhead caused due to usage of fault tolerance may be the reason that deadlines in RTSs are violated. Therefore, there is a need to optimize the usage of fault tolerance in RTSs.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To enable correct operation of RTSs in the presence of soft errors, in this thesis we consider a fault tolerance technique, Roll-back Recovery with Checkpointing (RRC), that efficiently copes with soft errors. The major drawback of RRC is that it introduces a time overhead which depends on the number of checkpoints that are used in RRC. Depending on how the checkpoints are distributed throughout the execution of the job, we consider the two checkpointing schemes: equidistant checkpointing, where the checkpoints are evenly distributed, and non-equidistant checkpointing, where the checkpoints are not evenly distributed. The goal of this thesis is to provide an optimization framework for RRC when used in RTSs while considering different optimization objectives which are important for RTSs. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The purpose of such an optimization framework is to assist the designer of an RTS during the early design stage, when the designer needs to explore different fault tolerance techniques, and choose a particular fault tolerance technique that meets the specification requirements for the RTS that is to be implemented. By using the optimization framework presented in this thesis, the designer of an RTS can acquire knowledge if RRC is a suitable fault tolerance technique for the RTS which needs to be implemented. The proposed optimization framework includes the following optimization objectives.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; For soft RTSs, we consider optimization of RRC with respect to AET. For the case of equidistant checkpointing, the optimization framework provides the optimal number of checkpoints resulting in the minimal AET. For non-equidistant checkpointing, the optimization framework provides two adaptive techniques that estimate the probability of errors and adjust the checkpointing scheme (the number of checkpoints over time) with the goal to minimize the AET.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; While for soft RTSs analyses based on AET are sufficient, for hard RTSs it is more important to maximize the probability that deadlines are met. To evaluate to what extent a deadline is met, in this thesis we have used the statistical concept Level of Confidence (LoC). The LoC with respect to a given deadline defines the probability that a job (or a set of jobs) completes before the given deadline. As a metric, LoC is equally applicable for soft and hard RTSs. However, as an optimization objective LoC is used in hard RTSs. Therefore, for hard RTSs, we consider optimization of RRC with respect to LoC. For equidistant checkpointing, the optimization framework provides (1) for a single job, the optimal number of checkpoints resulting in the maximal LoC with respect to a given deadline, and (2) for a set of jobs running in a sequence and a global deadline, the optimization framework provides the number of checkpoints that should be assigned to each job such that the LoC with respect to the global deadline is maximized. For non-equidistant checkpointing, the optimization framework provides how a given number of checkpoints should be distributed such that the LoC with respect to a given deadline is maximized.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Since the specification of an RTS may have a reliability requirement such that all deadlines need to be met with some probability, in this thesis we have introduced the concept Guaranteed Completion Time which refers to a completion time such that the probability that a job completes within this time is at least equal to a given reliability requirement. The optimization framework includes Guaranteed Completion Time as an optimization objective, and with respect to the Guaranteed Completion Time, the framework provides the optimal number of checkpoints, while assuming equidistant checkpointing, that results in the minimal Guaranteed Completion Time.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; In the modern world of today, we are surrounded with many electronic devices which offer previously unseen performance. These devices constitute a large part of the everyday consumer electronics such as laptops, tablets, smart phones, etc., but are also used in wide variety of domains such as automotive industry, avionics, medicine, etc. The constant demand for high performance has resulted in a rapid development of semiconductor technologies. Technology scaling has pushed the boundaries enabling fabrication of miniature devices. With such miniature devices, it is possible to integrate an entire system on a single chip, commonly referred to as System-on-Chip. For example, in a recent smart phone, the size of such chip is less than one square centimeter, and within this area, the number of transistors (the fundamental building block of modern electronic devices) is over one billion. This example shows that the gains of technology scaling are enormous. However, this comes at a cost, and that is that devices manufactured in the latest technologies may be affected by errors which cause malfunction. Lately, soft errors have been named as one of the most serious threats to computer systems designed in the latest semiconductor technologies.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Soft errors occur as a result of a particular type of faults, known as transient faults. Transient faults have a limited lifetime, namely these faults occur, remain present for a short time, but disappear afterwards. However, these faults, despite their short duration, often result in soft errors that may lead to a system failure. Therefore, soft errors have a significant impact on the reliability of the computer systems manufactured in the latest semiconductor technologies. While in the past soft errors were only a threat for devices which operate in harsh environments such as nuclear plants where high level of radiation exists, or avionics where at higher altitudes the cosmic radiation is higher, nowadays soft errors are a threat for all devices irrespective of the operational environment. The reason for this is that the major source of soft errors is the radiation of alpha-particles which are emitted from the package of the device itself. In the digital world where everything revolves around bits (a binary digit ``1&apos;&apos; or ``0&apos;&apos;), a transient fault can be interpreted as the outside force that flips a bit from ``1&apos;&apos; to ``0&apos;&apos;, or vice-versa, and the flipped bit is the representation of a soft error. If a soft error occurs in your smart phone, tablet or laptop you easily handle it by restarting the device. However, what happens if such an error occurs in a vital component of an airplane or a nuclear reactor? Can we simply restart?&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The field of research which tries to give answers to the previous questions is called Fault Tolerance. As the name suggests, fault tolerance enables correct operation of a device even in the presence of faults (errors). As a research topic, fault tolerance has been established along with the rise of the very first devices used in safety-critical applications such as avionics. Lately, the popularity of fault tolerance has been increased, especially when the manufacturing process has moved down to deep sub-micron semiconductor technologies where the size of the transistors has shrunk substantially, and their operation has become more susceptible to soft errors.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To enable correct operation in the presence of errors, fault tolerance provides techniques that are capable of error-detection, i.e. detect the presence of errors, and error-recovery, i.e. recover the system from errors. Usually, this is achieved by introducing a hardware and time redundancy.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hardware redundancy techniques cope with errors by designing devices or computer systems, such that multiple copies (replicas) of the physical building blocks are used. Every block performs a given operation and provides some kind of an output based on some inputs. If two identical copies process the same inputs, it is expected that they would both produce the same outputs. While these techniques ensure correct operation in the presence of errors, the main drawback is that these techniques are rather expensive. The cost of a device which contains multiple replicas is higher. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In contrast to the expensive hardware redundancy techniques, time redundancy techniques cope with errors by repeating the same operation utilizing the given hardware resources. The correct output is obtained by repeating the same operation at least twice. This increases the time required to obtain the final outcome, and therefore it results in much higher time overhead. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Roll-back Recovery with Checkpointing (RRC) is a well-known fault tolerance technique that efficiently copes with soft errors. Unlike traditional time redundancy techniques, where upon error detection the program is restarted from the beginning, RRC stores checkpoints (intermediate states of the execution of the program), and when errors are detected, it forces the program to roll-back to the latest stored checkpoint. The advantage of this technique over other fault tolerance techniques is that it does not require a substantial amount of hardware redundancy. However, the major drawback of RRC is that it introduces time overhead that depends on the number of checkpoints that are used. Thus, RRC introduces a time overhead that may have a negative impact on the computer system where it is used.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In general, computer systems are classified into real-time systems (RTSs) and non-RTSs, depending on the requirement to meet time constraints. For RTSs, the correct operation is defined as producing the correct output while satisfying a given time constraint (deadline). Depending on the consequences when deadlines are violated, RTSs are divided into soft and hard RTS. For soft RTSs, the consequences are not very severe. One example of a soft RTS can be a mobile phone where eventual deadline violation results in a dropped call. On the other hand, violating the deadlines in hard RTSs usually results in catastrophic consequences. An example of a hard RTS can be the braking control in a vehicle. RTSs are also affected by soft errors, and therefore there is a need to employ fault tolerance in RTSs as well. However, special consideration should be taken when employing fault tolerance in RTSs, due to the fact that fault tolerance usually introduces a time overhead.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The time overhead due to usage of fault tolerance in RTSs, may result in a missed deadline. To mitigate this effect, it is important to optimize the usage of fault tolerance in RTSs. The optimization objectives differ among soft and hard RTSs. For soft RTSs, where eventual deadline violation results in some performance degradation, it is more important to minimize the average execution time (the average time needed for the operation to complete), while for hard RTSs, where it is crucial to meet the deadlines, it is more important to maximize the probability that the deadlines are met.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; During the early design stage of an RTS, a designer of an RTS receives a specification of the RTS that is to be implemented. During this stage, the designer needs to explore different fault tolerance techniques and choose the one that satisfies the given specification requirements. To assist the designer in the decision making process, in this thesis, we provide an optimization framework for RRC when used in RTSs. By using this framework, the designer of an RTS can first decide if RRC is a suitable fault tolerance technique for the RTS that is to be implemented, and then if RRC is applicable, the designer can acquire knowledge on the number of checkpoints that need to be used and how these checkpoints need to be distributed. The proposed optimization framework considers multiple optimization objectives that are important for RTSs. In particular, for soft RTSs the optimization framework considers optimization of RRC with respect to AET. For hard RTSs, the optimization framework considers optimization of RRC with the goal to maximize the Level of Confidence (LoC), i.e. the probability that the deadlines are met. Since a specification of an RTS that is to be implemented may include some reliability requirements, in this thesis, we have introduced the concept of Guaranteed Completion Time, i.e. a completion time that satisfies a given reliability (LoC) constraint. The Guaranteed Completion Time varies with the number of checkpoints used in RRC. Therefore, the optimization framework considers optimization of RRC with respect to Guaranteed Completion Time.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4a5448ba-1d49-411f-b6eb-68689cf7d9ce</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="dissertationFinalPrint.pdf">https://portal.research.lu.se/files/3095008/4865033.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1776584</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>soft errors</topic> <topic>fault tolerance</topic> <topic>real-time systems</topic> <topic>checkpointing</topic> <topic>reliability</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7623-147-0</identifier> <identifier type="oldLupId">4865008</identifier> <part> <extent unit="pages"> <total>232</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-01-19T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>4a5448ba-1d49-411f-b6eb-68689cf7d9ce</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-12-03T13:22:36Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:35+02:00</recordDateApproved> </recordInfo> </mods>

The present thesis aims to investigate prescription sedative use and misuse in two kinds of samples - in the general population, with focus on its association with subjective health and quality life, and in the subpopulation of individuals with opioid dependence, with focus on treatment outcome in opioid maintenance treatment and mortality.&lt;br/&gt;&lt;br&gt; Materials and Methods: Prescription sedative misuse was studied in three Swedish datasets: 1) a general population survey (n =22,095), 2) a clinical pilot study for the treatment of opioid dependence (n =44 and 36, for the original study and the follow-up study, respectively), and 3) a national register-based study of individuals in opioid maintenance treatment ( n= 4,501).&lt;br/&gt;&lt;br&gt; Results: In the general population, sedative misuse was found to be associated with poor self-assessed mental health and poor quality of life. In individuals with opioid dependence, benzodiazepine misuse was found to be negatively associated with retention in opioid maintenance treatment. Prescription of sedatives was associated with mortality in individuals with opioid dependence, including associations between prescriptions of ‘z-drug’ hypnotics and pregabalin and overdose death.&lt;br/&gt;&lt;br&gt; Conclusions: It is important to be aware of the associations with mental health problems and quality of life in individuals with sedative misuse. In individuals with opioid dependence, clinicians also need to be aware of the increased risk of overdose and non-overdose death, as well as possible negative effects on treatment outcome, that come with sedative use and misuse.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Receptbelagda lugnande läkemedel används i behandling av framför allt ångest och sömnbesvär och har i det sammanhanget stor betydelse. Dessvärre kan beroende av dessa läkemedel utvecklas. Det förekommer även så kallad felanvändning av dessa läkemedel, d.v.s. användning utan recept, eller i högre doser, mer ofta, eller för annat syfte, än vad läkare har ordinerat. Sådan felanvändning sker ofta i syfte att självmedicinera mot olika psykiska besvär, t.ex. ångest, oro och sömnbesvär. Ett annat motiv kan vara att uppnå euforiserande effekter, d.v.s. ”bli hög”. Personer som har ett beroende av alkohol eller illegala droger kan även använda dessa mediciner för att lindra de besvär som uppstår vid minskad användning av ”huvuddrogen” (s.k. abstinensbesvär), eller för att få ökad effekt denna huvuddrog. Personer som redan utvecklat ett beroende av t.ex. alkohol eller opiater är särskilt känsliga för de beroendeframkallande effekterna av lugnade läkemedel och löper även risk för s.k. överdosering, vilket kan leda till döden. &lt;br/&gt;&lt;br&gt; Ämnet för denna avhandling är användning och felanvändning av lugnande läkemedel, dels i den allmänna befolkningen, dels i kliniska populationer med svårt narkotikaberoende individer, där felanvändning av dessa preparat medför stora hälsorisker. Avhandlingen består av fem arbeten. Två arbeten rör hur vanligt förekommande felanvändning av receptbelagda lugnade medel är i befolkningen och huruvida sådan felanvändning har samband med upplevd hälsa respektive livskvalitet. Tre av arbetena rör personer med opiatberoende. Två av dessa är baserade på en studie där man försökt behandla individer med opiatberoende med enbart substitutionsläkemedel, s.k. interimbehandling, för att snabbare kunna överföra dem som står i kö till fullskalig läkemedelsassisterad rehabilitering vid opiatberoende (LARO-behandling). Denna behandling har ett tydligt regelverk och innefattar både behandling med substitutionsläkemedel, psykologiskt stöd, och sociala insatser. I dessa arbeten studerades hur användning av receptbelagda lugnande läkemedel påverkar behandlingsförloppet. Det femte arbetet rör uppföljning av dödligheten hos en stor klinisk population av personer som erhållit LARO-behandling, och dess eventuella samband med förskrivning av olika lugnande läkemedel. &lt;br/&gt;&lt;br&gt; Arbete 1 och 2&lt;br/&gt;&lt;br&gt; Både arbete 1 och 2 utgår från en befolkningsundersökning som genomfördes av Lunds universitet i samarbete med dåvarande Folkhälsoinstitutet. Undersökningen syftade till att kartlägga förekomsten av droganvändning i befolkningen och hur olika faktorer hade samband med olika typer av droganvändning. Dessa båda artiklar fokuserar på felanvändning av receptbelagda lugnande läkemedel. Undersökningen besvarades av drygt 22 000 personer och svarsfrekvensen var 38% (52% efter att man tagit hänsyn till att man, som del i studiedesignen, skickat ut enkäten till fler individer i vissa befolkningsgrupper).&lt;br/&gt;&lt;br&gt; Förekomsten av felanvändning av receptbelagda lugnande läkemedel var 2,2 procent under det senaste året i den vuxna befolkningen. I det första arbetet sågs att felanvändning av receptbelagda lugnande läkemedel hade ett starkt samband med narkotikaanvändning, men också med självskattad psykisk ohälsa. &lt;br/&gt;&lt;br&gt; Den andra studien av samma material analyserade alkohol- och drogvanor i befolkningsmaterialet i förhållande till självrapporterad livskvalitet. Både felanvändning av receptbelagda läkemedel, riskkonsumtion av alkohol, och rökning hade samband med låg livskvalitet i detta material. Det starkaste sambandet med låg livskvalitet sågs hos personer som rapporterade felanvändning av lugnande läkemedel. &lt;br/&gt;&lt;br&gt; Arbete 3 och 4.&lt;br/&gt;&lt;br&gt; Arbete 3 och 4 undersökte felanvändning av de lugnande läkemedlen bensodiazepiner bland kliniska patienter med opiatberoende. Dessa arbeten baserades på en pilotstudie med 44 patienter, vars syfte var att undersöka ett nytt sätt att föra över obehandlade personer med opiatberoende (främst personer med heroinberoende) till LARO-behandling, den s.k. interimstudien i Lund. I arbete 3 var hypoteserna att felanvändning av bensodiazepiner skulle ha en negativ inverkan på möjligheten att kunna föras över till fullskalig LARO-behandling, samt öka risken för att patienterna fortsatte använda opiater under behandling. I studien sågs dock inga sådana samband mellan felanvändning av bensodiazepiner och övergång till LARO-behandling, eller fortsatt användning av opiater. Totalt kunde 57% föras över till fullskalig LARO-behandling.&lt;br/&gt;&lt;br&gt; I arbete 4 studerades huruvida felanvändning av bensodiazepiner före behandling, under interimfasen, samt under den fullskaliga LARO-behandlingen påverkade hur länge patienterna stannade kvar i behandling, s.k. retention. Andelen som stannade kvar i behandling var hög, 83%. Felanvändning av bensodiazepiner under fullskalig behandling var förknippad med en ökad risk för att inte kvarstå i LARO-behandlingen efter 9 månader. Det sågs även en tendens till att felanvändning av bensodiazepiner under interimfasen hade samband med risk att inte kvarstå i behandling efter 9 månader.&lt;br/&gt;&lt;br&gt; Arbete 5&lt;br/&gt;&lt;br&gt; I detta arbete studerades förutom bensodiazepiner även de receptbelagda sömnmedlen zopiklon, zolpidem och zaleplon (s.k. z-droger) och det receptbelagda ångestlindrande läkemedlet pregabalin. I denna studie, där ca 4 500 individer ingick, användes nationella registerdata för att undersöka om dödligheten hos opiatberoende patienter i LARO-behandling har samband med legal förskrivning av dessa lugnande läkemedel. Hypotesen var att samtliga dessa läkemedel skulle vara kopplade till en ökad risk för framför allt död till följd av överdos. Studien visade att förskrivning av bensodiazepiner var kopplat till ökad risk för död av andra orsaker än överdos, men inte till överdosdöd. Däremot var förskrivning av både z-droger och pregabalin kopplat till överdosdöd.&lt;br/&gt;&lt;br&gt; Betydelse&lt;br/&gt;&lt;br&gt; Arbete 1 och 2 ger stöd för att felanvändning av receptbelagda lugnande läkemedel ofta kan vara motiverat av en önskan att självmedicinera mot psykiska besvär eller andra problem i livet. Hos individer där felanvändning av läkemedel upptäcks kan det därför vara viktigt att utreda och behandla eventuell bakomliggande psykisk ohälsa. Det kan även vara av vikt att förhöra sig om hur personen i fråga har det i livet i övrigt, och vid behov ge information om vart man kan vända sig för hjälp med t.ex. relationsproblem, ekonomiska bekymmer, eller bristfällig bostadssituation.&lt;br/&gt;&lt;br&gt; Arbete 3 och 4 ger stöd för att felanvändning av bensodiazepiner förekommer i hög grad hos personer med opiatberoende, och att felanvändning av dessa preparat hos patienter i svensk LARO-behandling tycks påverka behandlingsförloppet negativt.&lt;br/&gt;&lt;br&gt; Arbete 5 visar på en ökad risk för dödliga överdoser bland individer med opiatberoende som erhåller recept på z-droger och pregabalin, samt ökad risk för död av annan orsak bland individer som erhåller recept på bensodiazepiner. Studien tycks ge anledning till stor försiktighet med förskrivning av dessa läkemedel till individer med opiatberoende.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6dff411e-dcbc-4635-80c4-d720fd240dfd</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Tove_Abrahamsson_KAPPA.pdf">https://portal.research.lu.se/files/3095074/8566617.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4812049</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Substance use</topic> <topic>Sedatives</topic> <topic>Anxiolytics</topic> <topic>Hypnotics</topic> <topic>Prescription drug miuse</topic> <topic>Benzodiazepines</topic> <topic>Z-drugs</topic> <topic>Pregabalin</topic> <topic>Self-assessed health</topic> <topic>Quality of life</topic> <topic>Opioid dependence</topic> <topic>Opiate maintenance treatment</topic> <topic>Mortality</topic> </subject> <subject authority="lup"> <topic>Drug Abuse and Addiction</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-241-2</identifier> <identifier type="oldLupId">8564948</identifier> <part> <detail type="volume"> <number>2016:15</number> </detail> <extent unit="pages"> <total>73</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-02-12T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>6dff411e-dcbc-4635-80c4-d720fd240dfd</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:36+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:36+02:00</recordDateApproved> </recordInfo> </mods>

This increase in functionality has been facilitated by scaling down the dimensions of the most important electronic component in modern electronics: the Si-based MOSFET. By reducing the size of the device, more transistors per chip area is possible. Smaller MOSFETs are also faster and more energy-efficient. In state of the art MOSFETs, the key dimensions are only few nanometers, rapidly approaching a point where the current scaling scheme may not be maintained. Research is ongoing to improve the device performance, mainly focusing on material and structural improvements to the existing MOSFET architecture. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis, MOSFETs based on nanowires, are investigated. Taking advantage of the nanowire geometry, the gate can be wrapped all-around the nanowires for excellent control of the channel. The nanowires are made in a high-mobility III-V semiconductor, InAs, allowing for faster electrons and higher currents than Si. This device type is a potential candidate to either replace or complement Si-based MOSFETs in digital and analogue applications. Single balanced down-conversion mixer circuits were fabricated, consisting of three vertically aligned InAs nanowire MOSFETs and two nanowire resistors. These circuits are shown to operate with voltage gain in the GHz-regime. Individual transistors demonstrated operation with gain at several tens of GHz. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A method to characterise the resistivity and metal-semiconductor contact quality has been developed, using the transmission line method adapted for vertical nanowires. This method has successfully been applied to InAs nanowires and shown that low-resistance contacts to these nanowires are possible. To optimise the performance of the device and reach as close to intrinsic operation as possible, parasitic capacitances and resistances in the device structure need to be minimised. A novel self-aligned gate-last fabrication method for vertical InAs nanowire transistors has been developed, that allows for an optimum design of the channel and the contact regions. Transistors fabricated using this method exhibit the best DC performance, in terms of a compromise between the normalised transconductance and sub-threshold swing, of any previously reported vertical nanowire MOSFET.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Under de senaste årtiondena har prestandan i elektriska kretsar växt i en rasande takt. Detta har lett till otaliga innovationer som har förbättrat samhället. Grunden till denna utveckling grundar sig i två uppfinningar: transistorn och den integrerade kresten. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Till skillnad från många andra grundläggande elektroniska komponenter har en transistor tre elektroder. En elektrisk ström skickas mellan två av elektroderna, såsom i ett motstånd, medans den tredje elektroden används för att styra hur stor denna ström ska vara. Det är detta styre, även kallad gate, som gör det möjligt att använda transistorn till digitala beräkningar, som är grunden i datorer, och till analoga applikationer, såsom radiosändare och mottagare. I en integrerad krets tillverkas idag miljardtals transistorer sida vid sida i halvledarmaterialet kisel. Att tillverka transistorerna på detta sätt är väldigt kostnadseffektivt och gör det möjligt att tillverka stora kretsar, såsom processorer. Under åren har tillverkningsmetoderna av integrerade kretsar utvecklats och lett till en förminskning av transistorernas storlek. De minsta dimensionerna i en modern transistor motsvarar idag ett par tiotal atomer i bredd. Ytterligare miniatyrisering är komplicerad och detta har lett till mycket forskning kring alternativa material och transistorstrukturer. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I detta arbete studeras användandet av halvledande nanotrådar i transistorer. Nanotrådar är cylindriska pelare i nanometerskalan. Genom att linda styret kring den nanotråden kan styrningen av strömmen göras effektivare än i konventionella transistorer. Nanotrådar kan byggas av flera halvledarmaterial, där indiumarsenid är ett av de materialen som har högst rörlighet för elektroner. Genom att kombinera materialegenskaperna av indiumarsenid med fördelarna av att nyttja en nanotråd, har välfungerande transistorer tillverkats. Under arbetets gång har InAs-transistorerna flyttats till kisel för att visa på ett kostnadseffektivt sätt att tillverka högprestandatransistorer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f97f26a5-e5a3-4fd2-b774-6e75dc56edb8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Martin_Berg_Thesis_Digital.pdf">https://portal.research.lu.se/files/3095181/7852390.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">38527126</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>MOSFET</topic> <topic>Metal-oxide-semiconductor field-effect transistor</topic> <topic>Transistor</topic> <topic>Vertical</topic> <topic>InAs</topic> <topic>III-V semiconductor</topic> <topic>Nanowire</topic> <topic>Fabrication</topic> <topic>DC</topic> <topic>Resistor</topic> <topic>TLM</topic> <topic>RF</topic> <topic>Mixer</topic> <topic>Circuit.</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> <topic>Nano-technology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Series of licentiate and doctoral theses</title> </titleInfo> <identifier type="issn">1654-790X</identifier> <identifier type="isbn">978-91-7623-382-5</identifier> <identifier type="oldLupId">7852217</identifier> <part> <detail type="volume"> <number>73</number> </detail> <extent unit="pages"> <total>160</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>suppl-Thesis Defence Presentation.pptx</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3095179/8054935.pptx</url> </location> <physicalDescription> <internetMediaType>application/vnd.openxmlformats-officedocument.presentationml.presentation</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-09-29T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>f97f26a5-e5a3-4fd2-b774-6e75dc56edb8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-27T14:09:52Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:38+02:00</recordDateApproved> </recordInfo> </mods>

The inflammatory process resulting in lung tissue destruction, emphysema, includes the excess of uninhibited proteases released from inflammatory cells. &lt;br/&gt;&lt;br&gt; alpha1-antitrypsin (AAT), an acute phase protein, is the prototypic member of the serpin super family and a major inhibitor of serine proteases such as neutrophil elastase. The clinical importance of AAT is highlighted in individuals with inherited AAT deficiency who exhibits an increased susceptibility to develop chronic inflammatory conditions including COPD. Both native (inhibitory) and modified (non-inhibitory) molecular forms of AAT, such as oxidized, nitrated, polymerized, cleaved and complexed with other proteins, have been detected in vivo. Recently it has become apparent that various forms of AAT express biological properties which are independent of protease inhibition. Studies characterizing these new biological activities of AAT are incomplete, particularly with regard to understanding the involvement of signalling mechanisms. &lt;br/&gt;&lt;br&gt; We hypothesize that novel biological activities of native AAT and its by-products may play an important role in the pathological processes characterized by chronic inflammation. We therefore examined; a) the effects of polymerized AAT on neutrophil activation, in vitro; b) the role of oxidized AAT on monocyte/macrophage activation both in vitro and in vivo; c) the effects of augmentation therapy on levels of plasma inflammatory markers and the properties of blood neutrophils obtained from a severe AAT-deficient COPD subject; d) the relationship between AAT levels and endotoxin receptor CD14 expression in young AAT-deficient subjects, and because low plasma AAT levels have been linked to diabetes type 1 we; e) measured plasma AAT levels in diabetes type 2 subjects. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Our findings show that: &lt;br/&gt;&lt;br&gt; 1. Some of the reported pro-inflammatory activities of polymerized AAT may be due to bacterial or other contaminants and that endotoxin-free polymerized AAT does not exhibit pro-inflammatory activity.&lt;br/&gt;&lt;br&gt; 2. Oxidized AAT induces a pro-inflammatory activation of both structural and inflammatory cells and may be involved in the development of COPD.&lt;br/&gt;&lt;br&gt; 3. Blood neutrophils from a COPD patient with severe PiZZ AAT deficiency isolated after augmentation therapy release significantly lower levels of IL-8 in response to zymosan as compared to neutrophils obtained before therapy. Our results support the idea that augmentation therapy with human AAT has anti-inflammatory effects.&lt;br/&gt;&lt;br&gt; 4. Blood monocytes from clinically healthy subjects with severe AAT-deficiency show significantly higher expression of CD14, an endotoxin receptor, than age and gender matched non-deficient controls. This finding in part explains why reduced AAT levels are related to increased susceptibility to infections and the development of chronic inflammation.&lt;br/&gt;&lt;br&gt; 5. A possible link may exist between low plasma levels of AAT and the development of diabetes type 2.&lt;br/&gt;&lt;br&gt; To summarize, the findings from our studies further improve our understanding of the biological activities of AAT and highlight the potentially broader modulatory role of AAT in inflammatory diseases.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6d6fb9d8-04f2-446f-ae8d-76188bfe63a7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling.pdf">https://portal.research.lu.se/files/3095450/1146199.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">856030</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Inflammation</topic> <topic>alpha1-Antitrypsin deficiency</topic> <topic>alpha1-Antitrypsin</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-07-1</identifier> <identifier type="oldLupId">1146198</identifier> <part> <detail type="volume"> <number>2008:54</number> </detail> <extent unit="pages"> <total>118</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-24T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>6d6fb9d8-04f2-446f-ae8d-76188bfe63a7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T12:59:42+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T12:59:42+02:00</recordDateApproved> </recordInfo> </mods>

The EPO effect is mediated via binding to the EPO receptor (EPOR), which induces activation of different intracellular signaling pathways. Recombinant human EPO (rhEPO) is also used in treatment of cancer patients with anemia but some studies have reported negative effects on patient survival. Here we demonstrate a correlation between increased Hb levels and tumor response in patients with metastatic breast cancer and anemia, treated with rhEPO. The improved tumor response seen in patients with increased Hb levels might be due to improved oxygenation in tumors counteracting negative effects of hypoxia. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; EPOR has also been found in non-hematopoietic tissues and in tumors of various origins. We have evaluated EPOR expression in breast tumors from a clinical trial evaluating tamoxifen treatment versus no adjuvant treatment. We found that high EPOR expression correlates to impaired tamoxifen response in patients with estrogen receptor (ER) positive tumors. EPOR expression also correlated to survival in these patients. When further investigating EPOR function we found that EPOR knockdown impaired proliferation in ER positive, but not ER negative breast cancer cells, supposedly via modulating effects of ER activity. EPOR knockdown also improved tamoxifen response in ER positive breast cancer cells. These effects were not dependent on EPO. Our results suggest an EPO-independent but ER-dependent function of EPOR in breast cancer cells.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hypoxia is a common feature of solid tumors and is believed to be a consequence of tumors outgrowing their vasculature. Tumor hypoxia is associated with a more aggressive phenotype and treatment resistance. The main regulators of the hypoxic response are the hypoxia-inducible factors (HIFs) 1 &amp;amp; 2. We have investigated HIF-1α and HIF-2α expression in breast cancer and found a correlation between HIF-2α expression and distant metastasis and impaired prognosis, suggesting that HIF-2α has an important role in tumor progression. We also show differential time and oxygen dependent regulation of the two different HIF-α subunits and differences in their contribution to inducing VEGF expression.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/72dbfe2b-f39e-4e07-b11c-d6998fc9e7f0</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Anna-Maria_Larsson_sid1-74.pdf">https://portal.research.lu.se/files/3096341/2278454.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1343443</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Center for Molecular Pathology, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Breast Cancer</topic> <topic>Anemia</topic> <topic>Hypoxia</topic> <topic>Erythropoietin (EPO)</topic> <topic>EPO receptor (EPOR)</topic> <topic>Estrogen Receptor (ER)</topic> <topic>Hypoxia-Inducible Factors (HIFs)</topic> <topic>Tamoxifen Response</topic> <topic>Proliferation</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-69-7</identifier> <identifier type="oldLupId">2278410</identifier> <part> <detail type="volume"> <number>2012:7</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-02-03T09:15:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

In type 1 diabetes the insulin producing β cells in the islet of Langerhans are destroyed by the immune system. The β cells, which are located in the pancreas, regulate blood glucose levels. The lack of insulin production requires administration of insulin. This is accomplished by insulin injections. Even though the treatment methods have been improved, we are still not able to artificially regulate the blood glucose levels as evenly as the β cells. The fluctuations of the blood glucose levels results in the long term in a number of complication, among the diabetic retinopathy. Diabetic retinopathy is the leading cause of blindness among the younger population.&lt;br/&gt;&lt;br&gt; Both to reduce the complications of diabetes and to find cures of the disease is important.&lt;br/&gt;&lt;br&gt; By using a model for diabetic retinopathy in mice we have been able to show that lack of the molecule N-CAM is protecting against the pathological neovascularization affecting diabetic patients.&lt;br/&gt;&lt;br&gt; The last 10 years have proven it possible to cure diabetes through transplantations of islets of Langerhans from cadaveric donors. The transplantations requires suppression of the immune response, this could lead to other complications. The amount of diabetic patients in need of transplantations far exceeds the availability of donors.&lt;br/&gt;&lt;br&gt; The use of stem cells to produce insulin producing β cells might be a possible way. To be able to direct the stem cells into β cells it is important to understand how these cells form during embryo development.&lt;br/&gt;&lt;br&gt; By the use of mice we have been able to study how blood vessels regulate the growth of the precursors of β cells. We have also been able to show that the formation of a tubular system in the pancreas is important for the regulation of which cell types that are to be formed.&lt;br/&gt;&lt;br&gt; Our results can be used to develop better methods for the production of β cells from stem cells.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Diabetes är en av de vanligaste folksjukdomarna och tusentals diagnostiseras med sjukdomen varje år. Det finns två typer av diabetes, typ 1 och typ 2. I typ 1 förstörs de insulin producerande β-cellerna som finns i de Langerhanska öarna av kroppens immunförsvar. β-cellerna har till uppgift att reglera blodsockernivåerna. Avsaknaden av egen insulinproduktion leder till diabetes som behandlas med insulininjektioner. Trots kraftigt förbättrade behandlingsmetoder kan vi inte artificiellt reglera blodsocker nivårena lika jämnt som β-cellerna gör. Fluktuationerna av blodsockernivåerna leder på sikt till en mängd komplikationer, bland dem diabetisk retinopati. Diabetisk retinopati är den vanligaste orsaken till blindhet hos den yngre befolkningen.&lt;br/&gt;&lt;br&gt; Både att mildra komplikationerna av diabetes och att hitta behandlingsmetoder för att bota sjukdomen är viktig.&lt;br/&gt;&lt;br&gt; I en musmodell för diabetisk retinopati har vi kunnat visa att avsaknaden av molekylen N-CAM skyddar mot delar av den sjukliga nybildningen av blodkärl som sker hos diabetiker.&lt;br/&gt;&lt;br&gt; Under de senaste 10 åren har forskare visat att det är möjligt att tillfälligt bota diabetes genom att transplantera Langerhanska öar från avlidna donatorer till diabetiker. Transplantationen kräver att immunförsvaret hämmas, vilket kan leda till andra komplikationer. Antalet diabetiker i behov av transplantation är mångt mycket större än tillgången på donatorer.&lt;br/&gt;&lt;br&gt; Att använda stamceller för att ta fram insulinproducerande β-celler skulle kunna vara en möjlig väg. För att kunna få stamcellerna att bilda β-celler är det viktigt att förstå hur dessa celler bildas under fosterutvecklingen. Genom att använda en musmodell har vi kunnat studera hur blodkärl reglerar tillväxten av förstadier till β-cellerna. Vi har även kunnat visa att bildandet av rörsystemet i pankreas är viktigt för vilka celltyper som skall bildas i pankreas. Våra resultat kan användas för att ta fram bättre metoder för att bilda β-celler från stamceller.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3460a5f6-d79d-427a-9564-23ecb6f87686</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Fredrik_WS_kappan.pdf">https://portal.research.lu.se/files/3099354/1746511.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">10199723</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Stem Cell Center, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>blood vessels</topic> <topic>pancreas</topic> <topic>endoderm development</topic> <topic>S1P1</topic> <topic>N-CAM</topic> <topic>diabetic retinopathy</topic> <topic>diabetes</topic> <topic>tubulogenesis</topic> <topic>Cdc42</topic> </subject> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-48-8</identifier> <identifier type="oldLupId">1746496</identifier> <part> <detail type="volume"> <number>2011:1</number> </detail> <extent unit="pages"> <total>196</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-01-07T13:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

An aging population with increased demands on quality of life and good visual acuity, has led to an increased rate of surgery and more surgeons needs to be trained. Training of new cataract surgeons is done on scarce wet-lab training but mainly on patients. Training is costly and complications are higher for new surgeons compared to experienced ones. In the airline industry simulators are used for training. Pilots have to prove competent before flying a new airplane. No such standards exist for new cataract surgeons.&lt;br/&gt;&lt;br&gt; Surgical simulators have been used in other surgical fields for training and reports have shown that training has improved performance on real operations. The purpose of this work was to validate Eyesi, a surgical simulator for cataract surgery training, and analyze learning curves. Furthermore we set out to investigate whether factors like stereoacuity and sex would be important for performance in the simulator.&lt;br/&gt;&lt;br&gt; Evidence for construct validity was found for cataract specific modules capsulorhexis, hydromaneuvers and phaco divide and conquer and for manipulating modules cataract navigation training, cataract forceps training and cataract cracking and chopping training. Analysis of learning curves showed significant improvement throughout training. Evidence for concurrent validity was established for the capsulorhexis module. For the hydromaneuvers and phaco modules, the innate simulator scoring could not distinguish surgical skill but discrimination was dependent on video based human scoring.&lt;br/&gt;&lt;br&gt; Stereoacuity was found to correlate with performance on the simulator but there were large individual variations. An individual’s sex had no influence on performance.&lt;br/&gt;&lt;br&gt; We have shown that Eyesi can differentiate cataract surgical skill and that naïve can train in the simulator and improve. Stereoacuity has an effect on performance but there were large individual variations. Simulation-based training has the potential to move the early learning curve out of the operating room.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Gråstarrskirurgi är en av de vanligaste kirurgiska ingreppen i Sverige med runt 90 000 operationer utförda varje år. En åldrande befolkning med ökade krav på livskvalitet och god synskärpa har lett till en ökad operationsfrekvens och fler kirurger behöver utbildas. Utbildning av nya gråstarrskirurger sker förutom ett fåtal träningstillfällen på grisar, framförallt på patienter. Utbildning är kostsam och komplikationer är högre för nya kirurger jämfört med erfarna. Inom flygindustrin används simulatorer för utbildning av nya piloter. Piloter måste klara fastställda krav innan de flyger nya plan. Ingen sådan standard finns för blivande gråstarrskirurger. &lt;br/&gt;&lt;br&gt; Kirurgisimulatorer har använts inom andra kirurgiska discipliner för träning och utbildning och rapporter har visat att simulatorträning har förbättrat utfall vid verkliga operationer. Syftet med detta arbete var att utvärdera Eyesi, en simulator för träning av gråstarrskirurgi, och undersöka inlärningskurvor. Dessutom ville vi undersöka om faktorer som stereoseende och en persons kön skulle ha betydelse för hur man presterade i simulatorn.&lt;br/&gt;&lt;br&gt; Vi fann att gråstarrskirurger klarade träningen i simulatorn bättre än icke-kirurger. Analys av inlärningskurvor visade klar förbättring vid träning. En individs stereoseende visade sig korrelera med prestation i simulatorn så att ju bättre stereoseende desto bättre prestation men det var stora individuella variationer. Vi såg ingen skillnad i prestation mellan män och kvinnor. Simulatorbaserad träning av gråstarrskirurgi har en potential att flytta den första delen av inlärning ut ur operationsrummet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/987e130f-e59c-49f7-beac-8ea44ebcf960</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Madeleine_Selvander_FINAL_20130409_utan_manuskript.pdf">https://portal.research.lu.se/files/3099963/3690978.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7416646</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>simulator</topic> <topic>cataract surgery</topic> <topic>learning</topic> <topic>training</topic> <topic>Eyesi</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-18-5</identifier> <identifier type="oldLupId">3690977</identifier> <part> <detail type="volume"> <number>2013:48</number> </detail> <extent unit="pages"> <total>104</total> </extent> </part> </relatedItem> <note type="teachingLearningHe">yes</note> <dateOther encoding="w3cdtf" type="defenseDate">2013-05-17T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>987e130f-e59c-49f7-beac-8ea44ebcf960</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:00+02:00</recordDateApproved> </recordInfo> </mods>

In cancer, these regulated processes are disrupted, resulting in uncontrolled cell growth. Regulation of RNA stability and turnover is important to maintain cellular homeostasis and can be controlled by various mechanisms. During stress, the cell can form cytoplasmic complexes of proteins and RNAs, called stress granules, to inhibit translation of proteins unnecessary for the cell during harmful conditions and focus translation on stress-related proteins. In neuroblastoma and breast cancer cell lines, we have found that the protein kinase Cα (PKCα) isoform can influence stress granule formation in a stress inducer-specific way. Depletion of PKCα led to a delayed stress response along with an initial loss of eIF2α phosphorylation in heat shock, but not arsenite, treated cells. G3BP proteins are well-known stress inducers and we identified a direct interaction between PKCα and the G3BP2 isoform.&lt;br/&gt;&lt;br&gt; G3BP2 belongs to a family of three homologous proteins with RNA-regulating capacities. With the aim to identify specific RNA targets, we performed a gene expression analysis and detected a negative regulation of the peripheral myelin protein (PMP22) by the G3BP1 isoform. The previously reported growth suppressing effects by PMP22 was here verified in breast cancer cells and we could show that G3BP1 influences growth regulation by reducing PMP22 expression, although not through mRNA destabilizing mechanisms.&lt;br/&gt;&lt;br&gt; Another RNA regulating mechanism that can promote or prevent tumor progression are mRNA silencing through miRNA. We analyzed miR-34c and its function in breast cancer and identified impaired cell growth, induced apoptosis and cell cycle G2/M arrest, which might be due to regulation of the anaphase-promoting complex protein Cdc23.&lt;br/&gt;&lt;br&gt; The tumor is not a homogenous compartment, but consists of various different cell types, both among the cancer cells as well as in the surrounding stroma. We have developed a methodological procedure for isolation and characterization of cancer- and stroma-specific genes using laser capture microdissection on FFPE triple negative breast cancers. Gene expression microarrays of these samples revealed compartment specific gene expression and enabled identification of stromal-specific gene signatures with tumor-predictive capacity.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Cancer är ett samlingsnamn för flera hundra sjukdomar som har gemensamt att de har fått en okontrollerad celldelning till följd av genetiska förändringar. Celldelning sker ständigt i vår kropp när gamla celler måste bytas ut och nya kopior bildas. Vid dessa processer sker det ofta mutationer i vårt DNA så att informationen förändras, vilket resulterar i att skadan kopieras till den nya cellen som därmed inte blir identisk med sin föregångare. Dessa fel förhindras i det flesta fall genom reparationsmekanismer i cellen, men ibland blir de nya förändringarna för starka och de felaktiga cellerna kan börja dela sig okontrollerat.&lt;br/&gt;&lt;br&gt; All grundinformation om hur cellen ska bli finns i cellens DNA, den så kallade arvsmassan. Informationen i arvsmassan läses av under kontrollerade former och ger då upphov till en ny molekyl som kallas RNA. Denna process heter transkription och efterföljs i många fall av translation, där informationen från RNA-molekylen fungerar som mall för bildandet av proteiner. Celler skickar signaler både mellan och inom sig för att styra olika processer och de flesta av dessa processer regleras av proteiner. På senare tid har man dock förstått att även RNA-molekyler är viktiga för att sköta regleringen i cellerna och i artikel I och artikel III har vi studerat två mekanismer som påverkar cellens RNA-nivåer.&lt;br/&gt;&lt;br&gt; Under cellulär stress, vilket uppstår i cellen när de normala förhållandena förändrats, t.ex. vid förhöjd temperatur eller minskad syrenivå, reagerar cellerna genom att utveckla olika skyddsmekanismser. En av dessa försvarsmekanismer omstrukturerar balansen för bildande av nya proteiner, så att cellen enbart producerar proteiner som kan reparera skadan. De RNA-molekyler som redan var producerade och redo för att bli proteiner tas nu omhand av cellen i ett skyddskomplex som kallas stressgranula. Där förvaras RNAt till dess att stressen försvinner. Om cellen fortfarande har behov av de skyddade RNA-molekylerna kan cellen snabbt starta proteinproduktionen istället för att börja om från DNA-nivån, och de RNA som inte behövs bryts ner. I den första artikeln har vi studerat ett protein som heter proteinkinase Cα (PKCα). Vi har sett att detta protein kan vara viktigt för bildandet av stressgranula och därmed skyddande av cellen. Vi har dessutom sett att PKCα kan binda till ett välkänt stress-skyddande protein som kallas G3BP. Denna bindning skulle kunna vara orsaken till att PKCα kan påverka skyddandet vid stress, men exakt hur det här är reglerat är inte klart. &lt;br/&gt;&lt;br&gt; G3BP är proteiner som finns i höga nivåer i flera olika typer av cancer och man har trott att dessa kan påverka cellernas förmåga att överleva och föröka sig. I artikel II visar vi att G3BP kan leda till ökad celldelning hos bröstcancerceller genom att minska nivåerna av det tillväxthämmande proteinet PMP22.&lt;br/&gt;&lt;br&gt; Cellens RNA-nivåer kan även regleras av en speciell sorts RNA-molekyl som kallas microRNA. Dessa microRNA binder till RNA-sekvensen och förhindrar att RNAt translateras till protein. I artikel III undersökte vi hur ett visst microRNA, miR-34c, kan påverka celldelning i bröstcancer eftersom detta microRNA visat sig skydda mot celldöd och öka nyproduktion av celler in andra cancer former. Vi såg att patienter med höga nivåer av miR-34c hade en bättre prognos än patienter med låga nivåer. I bröstcancerceller kunde vi se att miR-34c hade en negativ effekt på ett specifikt steg i celldelningsprocessen när den viktiga separationen mellan de två nyproducerade cellerna sker. Under celldelningsprocessen finns flertalet kontrollsteg och miR-34c verkar påverka åtminstone ett av dessa genom att minska RNA-nivåerna av Cdc23.&lt;br/&gt;&lt;br&gt; Inom tumörbiologiforskning tittar man mestadels på cancerceller och hur de beter sig, men tumörer består inte bara av cancerceller. Runt tumören finns omgivande celler som kan påverka cancercellernas utveckling, till exempel fibroblaster och inflammatoriska celler. I normala fall har de som uppgift att hindra felaktiga celler från att finnas kvar. Till sin hjälp har de ett strukturellt stöttande extracellulärmatrix och blodkärl och tillsammans kallas denna omgivning för stroma, eller när man pratar om tumörer, tumörcellsmikromiljö. Cancer cellerna kan lära sig att undvika signaler från det omgivande stromat och därmed främja tumörutveckligen. I artikel IV har vi utvecklat en metod för att kunna isolera cancerområden och stromadelar separat med lasermikrodissektion och utforska dessa delars genuttryck. Resultaten visade tydliga gensignaturer från stromadelarna vilka kunde användas för att bedöma prognos för bröstcancerpatienter, men även patienter med andra tumörformer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7b9e537f-30cc-4242-a707-b5c731cdf7e2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_G5_utan_artiklar.pdf">https://portal.research.lu.se/files/3100560/4394526.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3729022</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Translational Cancer Research, Department of Laboratory Medicine, Lund</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Breast cancer</topic> <topic>cellular stress</topic> <topic>proliferation</topic> <topic>PKCα</topic> <topic>G3BP</topic> <topic>PMP22</topic> <topic>miR-34c</topic> <topic>gene expression profiles</topic> <topic>stroma</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-81-6</identifier> <identifier type="oldLupId">4394429</identifier> <part> <detail type="volume"> <number>2014:55</number> </detail> <extent unit="pages"> <total>147</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-05-15T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>7b9e537f-30cc-4242-a707-b5c731cdf7e2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:06+02:00</recordDateApproved> </recordInfo> </mods>

The main problems with alcohol consumption from an economic point of view are lack of information for consumers when making consumption decisions, externalities, and the addictive nature. It is expected that this results in non-optimal consumption levels, causing higher costs than benefits. Studying the effects of alcohol consumption is thus important in order to increase information and to allow interventions and regulations to be implemented targeting market failures, with the overall purpose of improving societal and individual welfare.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The aim of this thesis is to study the effect of alcohol consumption on society, calculating the societal cost of consumption, and investigating possible improvements with regard to the estimation methods, data materials, and methodological assumptions. The focus of the latter is on issues related to labour market outcomes. Four research papers are included, together covering the aim.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper I conservatively estimates the societal cost of alcohol consumption in Sweden, including health and quality of life effects. The costs add up to a net cost of SEK 20.3 billion (0.9% of GDP) in 2002. To this should a partial estimate of reduced quality of life be added, totalling 122,000 QALYs. Sensitivity analyses indicate a sensitivity range of 50% of the net cost. However, even the lowest plausible estimate shows net societal cost of alcohol consumption. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper II investigates the effect of low alcohol consumption on health, measured as medical care costs and prevalence of alcohol-attributable diseases. It is found that low alcohol consumption increases medical care costs and episodes, with the exception for individuals above 80 years of age. Thus, the protective effect of low alcohol consumption for some diseases can not fully counter the detrimental effect from those diseases where low alcohol consumption increases the risk. Based on the epidemiological literature, low alcohol consumption should therefore not be considered to improve health. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper III studies a methodological issue in connection to the wage equation; whether failure to account for individuals’ drinking histories causes heterogeneity within commonly pooled consumption groups, potentially causing bias in econometric estimations. By applying a multinomial logit model, it is found that pooled drinking groups (current abstainers and light drinkers) are heterogeneous, and that this might implicate estimation bias due to confounding and misclassification. This study thus argues that it is imperative to account for drinking history when studying the effect of alcohol consumption. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper IV analyses the effect of women’s alcohol consumption on the likelihood of being long-term absent from work. Drinking history and selection effects are controlled for by applying a Heckman model. Women who are not a long-term light drinker is associated with an increase in the probability of long-term sickness-related absence, except for the insignificant effect of being a current light but former heavy drinker. The strongest effect is found for former drinkers (18%) followed by former abstainers (15%). Surprisingly are both being a long-term abstainer and a long-term heavy drinker associated with an increase of around 10%. Several simulation models were estimated, for example investigating the potential societal gain in productivity if all women were long-term light drinkers. It is found that the effect of alcohol consumption on long-term sickness-related absence is rather small on an individual level, although the added societal effect is substantial. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; It is shown in this thesis that alcohol consumption has a large societal impact. The societal cost was estimated in Paper I and Paper II – IV have supplied new information, with focus on the possible wage effect of alcohol consumption, in order to improve future estimations. Paper II rejects, based on the epidemiological literature, the possibility that the positive wage effect of low alcohol consumption is mediated through a protective health effect. According to Paper III, drinking history should be controlled for although this can not explain the commonly found inversed U-shaped relationship between alcohol and wages. Paper IV in turn suggests sickness-related absence as a mediator, potentially explaining (parts of) the alcohol – wage effect. Finally, the thesis has shown that the results of cost estimations are sensitive to what type of data is being used. Compared to a society without alcohol, the current Swedish consumption increases long-term sickness-related absence when using epidemiological data (Paper I), and decreases absence when using microdata and econometric methods (Paper IV).</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/61b5e07f-4950-4e6c-9eb8-9fbb8a7e7fde</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Essays_on_Societal_Cost_of_Alcohol_and_Related_Issues_-_A_Health_Economic_Analysis__kappa_.pdf">https://portal.research.lu.se/files/3100715/1487131.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">446877</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Wages</topic> <topic>Productivity loss</topic> <topic>Societal cost</topic> <topic>COI</topic> <topic>Consumption groups</topic> <topic>Alcohol consumption</topic> <topic>Drinking history</topic> <topic>Health</topic> <topic>Sickness absence</topic> <topic>Sweden.</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-86-8</identifier> <identifier type="oldLupId">1487130</identifier> <part> <detail type="volume"> <number>2009:98</number> </detail> <extent unit="pages"> <total>91</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-10-30T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>61b5e07f-4950-4e6c-9eb8-9fbb8a7e7fde</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:08+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:08+02:00</recordDateApproved> </recordInfo> </mods>

It contributes to the theoretical and methodological development of Islamic studies by introducing and using a queer approach to study marginalized sexualities in relation to Islam. &lt;br/&gt;&lt;br&gt; The work presented is a product of an intimate personal experience with the field (the gay community in Beirut). The analysis is based on material gathered through participation, observation, conversations, and especially interviews with eight young men.&lt;br/&gt;&lt;br&gt; Three kinds of intersecting orientations are investigated: those of being gay, Muslim, and male. The young men studied struggle with the expectations and stereotypes about sexual and gender identity, of what masculinity and being a man is all about, and with what is expected of them as being Muslim. One of the main arguments is that by separating the orientations and seeing how they interrelate as parallel lines, a clearer picture of the tactics that the young men studied employ when negotiating their different, and sometimes conflicting, orientations and identifications, emerges. &lt;br/&gt;&lt;br&gt; This dissertation advocates that marginalized sexualities should be studied and understood as provisional, discursively produced, unstable, performative, and decidedly partial identities, formed in relation to seemingly stable, normative, natural, and hegemonic identities.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0f0da1bc-e9ac-462e-9d72-e495eec796fb</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Queer Theory</topic> <topic>Gay</topic> <topic>Homosexuality</topic> <topic>LGBTQ</topic> <topic>Sexuality</topic> <topic>Islam</topic> <topic>Muslims</topic> <topic>Religion</topic> <topic>Orientation</topic> <topic>Masculinity</topic> <topic>Filedwork</topic> <topic>Observations</topic> <topic>Interviews</topic> <topic>Lebanon</topic> </subject> <subject authority="lup"> <topic>Philosophy, Ethics and Religion</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in History of Religions</title> </titleInfo> <identifier type="issn">1103-4882</identifier> <identifier type="oldLupId">4065100</identifier> <part> <detail type="volume"> <number>35</number> </detail> <extent unit="pages"> <total>256</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-10-26T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>0f0da1bc-e9ac-462e-9d72-e495eec796fb</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:11+02:00</recordDateApproved> </recordInfo> </mods>

An additional aim was to explore the use of mobility devices in everyday life among very old Swedish women during a five-year period. Further, the aim was to contribute to methodological development with regard to assistive device interventions and to investigate the basic psychometric proprieties of a new instrument for evaluating mobility-related participation. This thesis was based on two research projects; the ENABLE-AGE Project and the Nordic Assisted Mobility Evaluation Project (NAME). &lt;br/&gt;&lt;br&gt; The results of this thesis give an overview of the situation regarding assistive devices across five European countries: Sweden, Germany, the United Kingdom, Hungary and Latvia. Cross-national analyses show that the proportion of users, as well as the number of assistive devices in use per person, varied among the five European samples included. Overall, a higher proportion of very old people in the West European countries used assistive devices when compared to people in the East European countries. The use of mobility devices increased over a short period of time, this was most prominent in the Western European countries, and moreover the pattern of use changed during the one year study period. The findings in this thesis also highlight the heterogeneity and complexity of being a mobility device user at a very old age. The case study revealed that for three Swedish women the use of mobility devices impacted on activity and participation aspects, such as domestic work, shopping and socialising, during the ageing process, in complex and dynamic person-environment-activity transactions. In particular rollators were found to offer support for both transportation and activity performance. Further, the findings showed that complementary use of, e.g. a walking stick or walking frame, in different situations, enabled these women to manage everyday activities in spite of their functional limitations which were increasing over time. As to methodology contribution, an outcome assessment instrument, The Nordic Mobility-Related Participation Outcome Evaluation on Assistive Devices (NOMO 1.0), is presented. The instrument has a novel approach to outcome evaluation, targeting mobility-related participation outcomes after mobility device interventions. In addition this thesis contributed to theoretical development as regards assistive device research. Overall, the knowledge generated is relevant to support optimisation of mobility device use along the ageing process. From a European perspective, the findings give implications for future policy-making, planning and organisation of health care and social services, including provision of assistive devices and advancing occupational therapy practice across Europe.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e8a25df3-2ec7-4a31-9ea2-9954c9a58d45</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Lofkvist.pdf">https://portal.research.lu.se/files/3101341/1222624.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4503992</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Division of Occupational Therapy and Gerontology</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>assistive technology</topic> <topic>Assistive devices</topic> <topic>occupational therapy</topic> <topic>participation</topic> <topic>very old people</topic> </subject> <subject authority="lup"> <topic>Occupational Therapy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-45-3</identifier> <identifier type="oldLupId">1221701</identifier> <part> <detail type="volume"> <number>2008:92</number> </detail> <extent unit="pages"> <total>160</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-09-26T09:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Proper urination depends on an ability of the&lt;br/&gt;&lt;br&gt; bladder to adjust to increasing volume and to contract during micturition. A disturbance of bladder contractility&lt;br/&gt;&lt;br&gt; may affect continence. In the present thesis I have used genetic, biochemical and physiological approaches to&lt;br/&gt;&lt;br&gt; examine the role of caveolae and mircoRNAs in bladder function.&lt;br/&gt;&lt;br&gt; Caveolae are 60-80 nm large membrane invaginations present in a variety of cell types including smooth muscle.&lt;br/&gt;&lt;br&gt; A classical view is that caveolae organize the cell membrane and thereby regulate cell signalling. The proteins&lt;br/&gt;&lt;br&gt; caveolin-1 and cavin-1 are essential for biogenesis of caveolae in many cell types. The first aim of this thesis was&lt;br/&gt;&lt;br&gt; to address the significance of caveolae for detrusor function by using caveolin-1 and cavin-1 knockout mice.&lt;br/&gt;&lt;br&gt; Deletion of either caveolin-1 or cavin-1 led to lack of caveolae, reduced muscarinic and depolarisation-induced&lt;br/&gt;&lt;br&gt; contraction and impaired neuro-effector transmission. Lack of cavin-1 was moreover associated with bladder&lt;br/&gt;&lt;br&gt; hypertrophy. In vivo micturition patterns were however largely similar, arguing in favour of compensatory&lt;br/&gt;&lt;br&gt; mechanisms during normal voiding. In all, my findings show that the phenotypic overlap of two distinct knockout&lt;br/&gt;&lt;br&gt; models, both of which lack detrusor caveolae, is considerable. This establishes an important role of these&lt;br/&gt;&lt;br&gt; organelles for detrusor function.&lt;br/&gt;&lt;br&gt; MicroRNAs (miRNAs) are small non-coding RNAs that modulate gene expression by mRNA degradation and&lt;br/&gt;&lt;br&gt; translational repression. The biogenesis of most miRNAs depends on the enzyme Dicer. To investigate the role of&lt;br/&gt;&lt;br&gt; miRNAs in the urinary bladder I used two animal models: 1) smooth muscle-specific Dicer knockout mice and 2)&lt;br/&gt;&lt;br&gt; surgically induced bladder outlet obstruction, BOO. Depletion of miRNAs resulted in altered micturition pattern,&lt;br/&gt;&lt;br&gt; impaired contractility and reduced twitches in response to electrical field stimulation. Dicer deletion was&lt;br/&gt;&lt;br&gt; associated with reduced expression of L-type Ca2+ channels and reduced expression of the differentiation markers&lt;br/&gt;&lt;br&gt; desmin and calponin. Partial outlet obstruction, on the other hand, resulted in altered expression of 50 miRNAs,&lt;br/&gt;&lt;br&gt; supporting a role of this class of RNAs in bladder pathology. Most impressive was a five to ten-fold increase in&lt;br/&gt;&lt;br&gt; expression of miR-132/212. Transcription factor binding site analysis pointed to the involvement of Ahr and Creb&lt;br/&gt;&lt;br&gt; in miR-132/212 induction. Targets of these miRNAs correlated inversely with the miR-132/212 levels.&lt;br/&gt;&lt;br&gt; Overexpression of antimirs and mimics for miR-132/212 caused reciprocal changes in cell proliferation. Taken&lt;br/&gt;&lt;br&gt; together, my findings demonstrate that miRNAs play a key role for normal detrusor function and argue that they&lt;br/&gt;&lt;br&gt; regulate gene expression and cell proliferation following obstruction.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ae2d3f49-6970-4426-a295-3b9902fd2ee5</url> </location> </relatedItem> <originInfo> <publisher>Cellular Biomechanics</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-055-5</identifier> <identifier type="oldLupId">4810404</identifier> <part> <detail type="volume"> <number>2014:126</number> </detail> <extent unit="pages"> <total>70</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-14T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>ae2d3f49-6970-4426-a295-3b9902fd2ee5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:16+02:00</recordDateApproved> </recordInfo> </mods>

This was achieved by a reflecting filter for inhalational anaesthetics made of active carbon. The principle has been developed into the commersially available Anesthetic Conserving Device (ACD, AnaConDa®).The ACD is a modified heat- and moisture exchanger (HME) containing av bacterial and viral filter as well as a carbon filter. The ACD can be used during surgery for administering the inhalational agents isoflurane and sevoflurane as an alternative to low-flow anaesthesia systems. It can also be used in intensive care units to administer sedation using isoflurane or sevoflurane to critically ill patients. The thesis is based on four papers.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper I it is shown that that the wash-in kinetics for sevoflurane delivered by the ACD is similar to a vaporiser. With the ACD, end-tidal sevoflurane accurately reflects arterial sevoflurane tension whereas inspired tension may be underesteimated. Despite an increase in tidal volume of patients in a group with an ACD corresponding to the larger internal volume of the device compared to a conventional HME, the PaCO2 was considerably higher in this group. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper II CO2 exchange and airway dead space is compared using an HME, ACD without reflecting filter and ACD with reflecting filter in a laboratory set-up. It is shown that the ACD binds CO2 resulting in a dead space effect 180 ml in excess of its internal volume. This is due to adsorption of CO2 in the ACD during expiration and return of CO2 during the following inspiration.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper III the ACD is used without inhalational anaesthetics in patients as well as in a laboratory set-up with varying temperature and humidity. It is confirmed that an ACD used in humans as well as in a test lung increases the dead space effect and CO2 rebreathing to a greater extent than can be explained by its internal volume. This is caused by adsorption of CO2 in the ACD during expiration and release of CO2 during inspiration.

It is shown that sevoflurane attenuates but does not abolish rebreathing of CO2, thereby reducing the dead space effect of the ACD.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conlusion, the ACD causes a dead space effect larger than its internal volume due to CO2 rebreathing. This may influence the clinical use of the ACD.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Anesthetic Conserving Device (AnaConDa®) är ett nytt, kommersiellt tillgängligt, hjälpmedel för att ge narkosgaser. AnaConDa® är en förgasare och återandningsfilter, vilken ansluts till patientens andningstub under operation eller intensivvård. Filtret fungerar med hjälp av kolpartiklar som binder utandade narkosgasmolekyler till sig vilka återandas vid nästa inandning. Vid vanlig narkosgasdosering återanvänds mer än 90% av utandad narkosgas vid nästa inandning. AnaConDa® fungerar dessutom som fuktvärmeväxlare vilka alltid används vid ventilatorbehandling för att minska kroppsvätskeförluster via andningsvägarna. AnaConDa® kan användas med narkosgaserna isofluran och sevofluran. Till skillnad från intravenösa narkosmedel verkar narkosgaserna isofluran och sevofluran minska skadan på hjärtmuskeln i samband med syrebrist (s.k. farmakologisk konditionering). Detta har lett till ökad användning av narkosgaser i samband med hjärtkirurgi före, under och efter ingreppet. En förutsättning för att ge narkosgas har hittills varit tillgång till narkosapparat med förgasare vilka i regel bara finns på operationsavdelningar. AnaConDa®:n har löst de tekniska/praktiska och miljömässiga problemen för att kunna ge narkosgas utanför dessa, såsom inom intensivvård där ventilatorvårdade patienter behöver rogivande läkemedel.&lt;br/&gt;&lt;br&gt; Vi har undersökt hur narkosgas tas upp i blodet hos patienter som ska genomgå en hjärtoperation vid tillförsel via en AnaConDa® jämfört med via en vanlig narkosapparat med förgasare (studie I). Likvärdiga koncentrationer av narkosgasen sevofluran uppmättes i blodet oavsett om gasen tillfördes via förgasare eller AnaConDa®. Det finns mätbara skillnader i volym hos en vanlig fuktvärmeväxlare och den större AnaConDa®. Volymen av det inre av anordningen utgör s.k. skadligt rum varmed avses att gasutbyte med blodet inte sker i denna del av andningssystemet. Det större skadliga rummet hos AnaConDa kompenserades med motsvarande ökning av andetagsvolymen hos de patienter som fick narkosgas via AnaConDa®. Trots kompensation för volymsskillnaden mellan fuktvärmeväxlare och AnaConDa® så fann vi att koldioxidhalten i blodet hos patienter där AnaConDa® använts var högre än förväntat. Hög koldioxidhalt i blodet kan leda till oregelbunden hjärtrytm, förhöjt tryck i skallen och i blodkretsloppet genom lungorna.&lt;br/&gt;&lt;br&gt; 46&lt;br/&gt;&lt;br&gt; AnaConDa®:ns eftertraktade egenskap är återandning och –utnyttjande av narkosgas. I studie II undersökte vi om filtret ger återandning av koldioxid i laboratorieförsök med en 20 liters plastflaska som lungmodell. Under dessa förhållanden gav AnaConDa® filtret en betydande återandning av koldioxid. Varje andetag behövde ökas med ca 180 ml (normalt andetag hos vuxen människa cirka 500 ml) för att bibehålla ursprunglig koldioxidnivå i andningsluften när AnaConDa®:n användes istället för en vanlig fuktvärmeväxlare.&lt;br/&gt;&lt;br&gt; I studie III undersöktes om fukt och värme påverkar AnaConDa®-filtrets återandning av koldioxid. Hos patienter efter hjärtoperation kopplades AnaConDa® in istället för en vanlig fuktvärmeväxlare och storleken på det skadliga rummet och koldioxidåterandningen mättes. När AnaConDa® användes hos patienter uppmättes det skadliga rummet betydligt större än skillnaden i intern volym med en fuktvärmeväxlare. Koldioxid återandades betydligt mer vid AnaConDa- användning (53%) jämfört med vid fuktvärmeväxlare (29%). I laboratorieförsök visades att fukt minskade koldioxidåterandning och storleken på det skadliga rummet. Värmehöjning från rumstemperatur till kroppstemperatur påverkade däremot inte koldioxidåterandning och storleken av det skadliga rummet.&lt;br/&gt;&lt;br&gt; När narkosgasen sevofluran användes i AnaConDa®:n i studie IV minskade såväl återandningen av koldioxid hos hjärtopererade patienter som det skadliga rummet. Den återandade halten koldioxid sjönk ju högre koncentration av sevofluran som användes. Det skadliga rummet uppmättes till 40 ml större än AnaConDa®:s fysiska interna volym vid den högsta använda sevoflurankoncentrationen. I laboratorieförsök visades att koldioxidåterandningen avtog i närvaro av sevofluran och storleken på skadligt rum minskade. Sevofluran minskade således, men tog inte helt bort, koldioxidåterandningen och storleken på skadligt rum vid AnaConDa® användning.&lt;br/&gt;&lt;br&gt; AnaConDa® är ett nytt hjälpmedel för tillförsel av narkosgaserna isofluran och sevofluran till patienter i behov av sedering/sövning både på operation och inom intensivvård. Denna avhandling visar emellertid att inte bara narkosgas reflekteras i AnaConDa®:s filter utan också koldioxid. Detta bör beaktas vid användning av AnaConDa®.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e1b6440d-1b3d-4604-a9e5-9aead198cd93</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Louise_Walther_Sturesson_Kappa_frAY_n_tryckeri.pdf">https://portal.research.lu.se/files/3101435/3565314.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2644901</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Anaesthesiology and Intensive Care</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>anesthetic conserving device</topic> <topic>inhalational anaesthesia</topic> <topic>carbon dioxide</topic> <topic>Gas exchange</topic> </subject> <subject authority="lup"> <topic>Anesthesiology and Intensive Care</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-00-0</identifier> <identifier type="oldLupId">3565281</identifier> <part> <detail type="volume"> <number>2013:30</number> </detail> <extent unit="pages"> <total>55</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-04-05T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>e1b6440d-1b3d-4604-a9e5-9aead198cd93</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:16+02:00</recordDateApproved> </recordInfo> </mods>

It is caused by quantitative and/or qualitative defects of the von Willebrand factor (VWF). The severity of the disease can vary considerably, as can the hereditary patterns. The variable phenotypes of VWD have given rise to a classification scheme that divides the disease into three types according to how it is manifested and inherited. The genetics of, especially type 1, VWD is relatively complicated and many aspects of it remain to be elucidated. The purpose of these studies was therefore to investigate and clarify certain genetic mechanisms that underlie VWD.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; When we investigated to what extent co-segregation exists in type 1 VWD, we found that the disease is linked to the VWF gene in a majority (27 of 31) of Swedish type 1 VWD families. Several common disease haplotypes probably exist for type 1 VWD in Sweden, which suggests founder effects. The Y1584C variation is not as common in the Swedish type 1 VWD population as it is in some other populations. We confirmed that blood group O is over-represented among type 1 VWD patients in Sweden. Apart from certain misunderstandings, the participants in the linkage study were found to have a satisfying level of knowledge of the genetics of the disease. In general, patients, younger individuals, and women have a higher knowledge about the genetics causing type 1 VWD than do healthy relatives, older individuals, and men, respectively.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Inherited recessively, the C570S mutation causes a distinct subtype of type 2A VWD characterized by very low plasma FVIII and VWF levels and the exclusive presence of the dimeric form of VWF in plasma. The findings define a structural element that is indispensable for VWF multimerization.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Inherited dominantly, the N1421K mutation causes type 2M VWD characterized by moderately decreased plasma FVIII and VWF levels, disproportionately low plasma VWF:RCo levels, and an apparently normal multimeric pattern. The findings indicate a structural element in the A1 domain that is necessary for proper GPIb binding.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9c6580b2-a69e-4f98-b7b2-1bc5999ac7f4</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Elsa_L._kappa.pdf">https://portal.research.lu.se/files/3101622/1235656.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5098340</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>mutation</topic> <topic>bleeding</topic> <topic>coagulation</topic> <topic>von Willebrand disease</topic> <topic>genetics</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-42-2</identifier> <identifier type="oldLupId">1235475</identifier> <part> <detail type="volume"> <number>2008:89</number> </detail> <extent unit="pages"> <total>105</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-03T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>9c6580b2-a69e-4f98-b7b2-1bc5999ac7f4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:18+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:18+02:00</recordDateApproved> </recordInfo> </mods>

Sjukdomarna leder till stort lidande för både patienter och anhöriga och beräknas kosta samhället 422 miljarder amerikanska dollar årligen. Den vanligaste demenssjukdomen är Alzheimers sjukdom och den utgör ca 60–70% av alla demenssjukdomar. Sjukdomarna blir allt vanligare och år 2050 beräknas över 100 miljoner människor vara drabbade av Alzheimers sjukdom. Främst kommer ökningen att ske i låginkomstländer. Det är därför viktigt att det finns billiga och enkla instrument för att tidigt kunna ställa diagnos och för att utvärdera behandling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Syfte&lt;br/&gt;&lt;br&gt; Att utvärdera de enkla kognitiva testerna kubkopiering, klockritning, A Quick Test of Cognitive Speed (AQT) och Mini-Mental Test (MMT, på engelska kallat Mini- Mental State Examination, MMSE) vid tidig diagnostik, behandlingsutvärdering och differentialdiagnostik.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Patienter i artiklarna I - IV&lt;br/&gt;&lt;br&gt; I. 85 patienter med Alzheimers sjukdom följdes före och efter behandling. &lt;br/&gt;&lt;br&gt; II. 33 patienter med Lewy body demens jämfördes i kognitiv testning med 66&lt;br/&gt;&lt;br&gt; matchade patienter med Alzheimers sjukdom. &lt;br/&gt;&lt;br&gt; III. 75 patienter med Alzheimers sjukdom följdes före och efter behandling. &lt;br/&gt;&lt;br&gt; IV. 99 patienter med lindrig kognitiv svikt följdes under 5 år, varpå 52 patienter&lt;br/&gt;&lt;br&gt; drabbades av olika demenssjukdomar medan 47 patienter inte försämrades.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Fynd&lt;br/&gt;&lt;br&gt; I. Kubkopiering var användbart för att utvärdera läkemedelsbehandling med acetylkolinesterashämmare vid Alzheimer.&lt;br/&gt;&lt;br&gt; II. Kubkopiering, MMSE och klockritning kunde skilja på sjukdomarna Lewy body demens och Alzheimer.&lt;br/&gt;&lt;br&gt; III. Testet AQT var dubbelt så känsligt som MMSE för att utvärdera behandling med acetylkolinesterashämmare vid Alzheimers sjukdom.&lt;br/&gt;&lt;br&gt; IV. Klockritning, MMSE och AQT är lika bra som analys av ryggmärgsvätska på att förutsäga vilka patienter med lindrig kognitiv svikt som senare kommer att utveckla Alzheimers sjukdom och andra demenssjukdomar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattning&lt;br/&gt;&lt;br&gt; Denna avhandling har bidragit med ny kunskap om hur enkla kognitiva tester kan tolkas och användas för att (1) utvärdera behandling vid Alzheimers sjukdom, (2) kunna skilja på Lewy body demens och Alzheimers sjukdom och (3) kunna förutsäga vilka patienter med lättare minnes- och tankeproblem som senare utvecklar Alzheimers sjukdom eller andra demenssjukdomar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/27773d34-3e7d-430f-ac1b-0139f32e1cca</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappan.pdf">https://portal.research.lu.se/files/3104935/1971276.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9133093</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Clinical Memory Research Unit, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Cognitive tests</topic> <topic>neuropsychology</topic> <topic>Alzheimer’s disease</topic> <topic>dementia with Lewy bodies</topic> <topic>mild cognitive impairment</topic> <topic>treatment evaluation</topic> <topic>acetylcholinesterase inhibitors</topic> <topic>differential diagnosis</topic> <topic>longitudinal studies</topic> <topic>dementia</topic> <topic>cerebrospinal fluid</topic> <topic>forecasting</topic> </subject> <subject authority="lup"> <topic>Medical and Health Sciences</topic> <topic>Clinical Medicine</topic> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-13-0</identifier> <identifier type="oldLupId">1971270</identifier> <part> <detail type="volume"> <number>2011:64</number> </detail> <extent unit="pages"> <total>95</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-06-18T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>27773d34-3e7d-430f-ac1b-0139f32e1cca</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:44+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:44+02:00</recordDateApproved> </recordInfo> </mods>

Previous evaluations of retinal function, and treatment of these conditions have been subjective methods depending on the examiner or the collaboration with the examined patient. Retinal structure has been based on the subjective evaluation of the ophthalmologist. Development of ff-ERG, multifocal ERG (mfERG), which reflects central retinal function, and optical coherence tomography (OCT) which analyzes central retinal structure has enhanced our possibility to evaluate the retinal disorders in a more objective way. &lt;br/&gt;&lt;br&gt; The aim of this thesis was to correlate central retinal function (mfERG) to central retinal structure (OCT) in diabetic macular edema and in retinal detachment before and after surgery. Where appropriate total retinal function (ffERG) was evaluated. A standardized combination of OCT and mfERG was developed.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Retinal function correlated negatively to retinal thickness, the presence of hard exudates and the nasal part of macula, in patients with diabetes. &lt;br/&gt;&lt;br&gt; Reduced amplitude and prolonged implicit time correlated to macular central thickness. When the central macular thickness exceeded 300 µm the reduced amplitude and prolonged implicit time seemed to be more pronounced. Eyes with hard exudates had prolonged implicit time compared to eyes without hard exudates, despite no differences in macular thickness. Hard exudates prolong the implicit time, even at a distance from the fovea center. The nasal macular area showed lower amplitude and prolonged implicit time compared to the temporal. Evaluation of laser treatment showed increased mfERG amplitude, reduced macular thickness and resolved hard exudates.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In retinal detachment electroretinographic deterioration occurs both in short-term and long-term detachment. In long-term detachment the deterioration of retinal function is pronounced with no detectable macular function. After the scleral buckling procedure, in short-term detachment mfERG amplitude and rod function improves postoperatively. After vitrectomy including retinectomy in long-term detachment retinal function can improve.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A combination of mfERG and OCT, and where appropriate, ffERG, are suitable tools for further studies regarding retinal and macular function and structure in diabetic maculopathy and retinal detachment, and evaluation of treatment.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/832f09d7-ae95-4944-a13a-bb3bd92ce394</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>mfERG</topic> <topic>OCT</topic> <topic>ff-ERG</topic> <topic>diabetes</topic> <topic>macular edema</topic> <topic>retinal detachment</topic> <topic>scleral buckling</topic> <topic>retinectomy</topic> </subject> <subject authority="lup"> <topic>Ophthalmology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-86671-89-1</identifier> <identifier type="oldLupId">1895832</identifier> <part> <detail type="volume"> <number>2011:41</number> </detail> <extent unit="pages"> <total>116</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-05-13T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>832f09d7-ae95-4944-a13a-bb3bd92ce394</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:49+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:49+02:00</recordDateApproved> </recordInfo> </mods>

DA replacement with L-DOPA is the standard therapy for PD. However, with treatment duration many patients face the severe treatment complication of L-DOPA-induced dyskinesia (LID), constituting in abnormal involuntary movements (AIMs). The etiology of PD and LID is largely unknown, but both pathophysiological states are linked to DA. How neurons in a DA-receptive brain region adapt to the pathophysiological states of PD and LID is the topic of this thesis’ work.&lt;br/&gt;&lt;br&gt; The striatum is the “hub” into the basal ganglia network and implicated in movement control. Striatal spiny projection neurons (SPNs) divide into two subpopulations, forming the so-called direct and indirect pathway of the basal ganglia. Due to the expression of different DA receptors, direct and indirect pathway SPNs (dSPNs and iSPNs, respectively) are oppositely modulated by DA.&lt;br/&gt;&lt;br&gt; D1 receptor (D1R) stimulation in the DA-denervated, parkinsonian striatum leads to a supersensitive activation of ERK1/2 in dSPNs. This aberrant signaling activation is widely believed to be a core mechanism leading to the development of LID. In the first study we investigated which signaling pathways participate in this D1R-induced ERK1/2 activation. We found a distinct and complex interaction between PKA- and Ca2+-dependent pathways, which is critically modulated by mGluR5. In the second study we further investigated the antidsykinetic profile of mGluR5 antagonist treatment, finding that the choice of animal model influences the outcome of antidyskinetic therapy testing. Striatal adaptations, sensitive to beneficial mGluR5 inhibition, appear not to be represented in only partially DA-denervated animals.&lt;br/&gt;&lt;br&gt; In the last study we investigated possible homeostatic mechanisms in SPNs during PD and LID. We found that both iSPNs and dSPNs display potential homeostatic adaptations of excitability that are likely to counteract the loss of DA signaling and balance perturbations in firing activity. The changes were oppositely directed in iSPNs and dSPNs, reflecting the bidirectional modulation by DA. In contrast, PD-associated dendritic atrophy was found in both subpopulations and is independent of DAergic signaling. Synaptic adaptations in SPNs in PD and LID appeared not to follow homeostatic ruling. Specifically, we found that SPNs do not exhibit synaptic scaling, but rather selective elimination of spines. The failure to preserve the pattern of weighted synaptic inputs suggests that SPNs may not be able to appropriately regulate basal ganglia related behavior in PD and LID.&lt;br/&gt;&lt;br&gt; Taken together, the results of this thesis reveal new molecular and physiological adaptations of SPNs in experimental models of PD and LID. Identifying if they are compensatory or maladaptive is difficult, but the more our understanding proceeds the better we can refine preclinical animal models and define potential treatment options for PD and LID.</abstract> <abstract lang="swe">&lt;b&gt;Abstract in German&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Die Parkinson-Krankheit („Parkinson”) ist eine neurodegenerative Erkrankung die durch den Verlust von Dopamin-produzierenden Nervenzellen in der Substantia Nigra und daraus resultierenden, typischen motorischen Symptomen gekennzeichnet ist. Die Standardbehandlung für Parkinson ist die Gabe von L-DOPA, zum Zweck der Ersetzung des verlorengegangen Dopamins. Eine Langzeittherapie mit L-DOPA führt jedoch häufig zu schweren Nebenwirkungen, in Form von unfreiwilligen und abnormalen Bewegungen, den sogenannten L-DOPA induzierten Dyskinesien (LID). Die Ätiologie beider motorischer Krankheitsbilder ist größtenteils unbekannt, jedoch ist Dopamin ein gemeinsamer Nenner. Die Veränderungen von Nervenzellen in einer Dopamin-empfänglichen Gehirnregion bei Parkinson und LID ist Gegenstand der vorliegenden Dissertation.&lt;br/&gt;&lt;br&gt; Das Striatum gehört zu den Basalganglien, welche in die Steuerung von Bewegungen eingebunden sind. Die Hauptnervenzellen im Striatum sind in zwei Populationen unterteilt und bilden den sogenannten direkten und indirekten Projektionsweg der Basalganglien. Diese zwei Populationen werden aufgrund unterschiedlicher Ausstattung mit Dopamin-Rezeptoren gegensätzlich von Dopamin moduliert.&lt;br/&gt;&lt;br&gt; Die Stimulierung des D1 Rezeptors im parkinsonoiden Striatum führt zu einer super-sensiblen Aktivierung der Kinasen ERK1/2. Man nimmt weitestgehend an das diese abnormale Signalaktivierung einen Kernmechanismus für die Entwicklung von LID darstellt. In der ersten Studie haben wir daher untersucht, welche Signalwege an der D1 Rezeptor-induzierten ERK1/2 Aktivierung beteiligt sind. Wir konnten eine komplexe Interaktion von PKA- und Calcium-abhängigen Signalwegen aufzeigen, welche zudem maßgeblich von mGluR5 moduliert wird. In der zweiten Studie haben wird daraufhin das anti-dyskinetische Profil der Behandlung mit einem mGluR5 Antagonisten charakterisiert. Es zeigte sich, dass die Wahl des Tiermodelles einen kritischen Einfluss auf das Ergebnis der antidyskinetischen Therapie hat. Jene Veränderungen von Zellen im Striatum, welche eine nützliche Blockierung von mGluR5 möglich machen, sind in Tiermodellen mit teilweiser Dopamin Denervierung nur unzureichend vorhanden.&lt;br/&gt;&lt;br&gt; In der letzten Studie untersuchten wir homeostatische Mechanismen in striatalen Nervenzellen bei Parkinson und LID. Beide Populationen zeigten homeostatische Anpassungen von zellulärer Erregbarkeit, als mögliche Gegenmaßnahme zum Verlust von Dopamin und zur Erlangung eines Ausgleiches der neuronalen Feueraktivität. Diese Anpassungen waren gegensätzlich gerichtet in den Populationen. Eine Atrophie von Dendriten war im Gegensatz dazu jedoch gleichermaßen in beiden Populationen zu finden und scheint daher dopaminunabhängig zu sein. Weitere Anpassungen von Synapsen bei Parkinson und LID folgten nicht den homeostatischen Regeln. Im Besonderen konnten wir keine Skalierung der synaptischen Stärken beobachten, sondern vielmehr eine selektive Eliminierung von Synapsen. Dies legt die Vermutung nahe, dass striatale Nervenzellen bei Parkinson und LID nicht in der Lage sind die Funktion der Basalganglien angemessen zu regulieren.&lt;br/&gt;&lt;br&gt; Die Anpassungen im Striatum sind ein wichtiger Faktor bei beiden Krankheitszuständen. Hierbei ist es schwer, kompensatorische von fehlgeleiteten Anpassungen zu unterscheiden. Je mehr Wissen wir jedoch über diese erlangen, desto besser können wir Tiermodelle optimieren und potenzielle Therapieoptionen für Parkinson und LID identifizieren.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f5d30aa8-9496-4582-a59d-00f0fc7a4ec2</url> </location> </relatedItem> <originInfo> <publisher>Neurobiology, Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Striatum</topic> <topic>Parkinson’s disease</topic> <topic>L-DOPA-induced dyskinesia</topic> <topic>ERK1/2</topic> <topic>mGluR5</topic> <topic>homeostatic plasticity</topic> <topic>SPN</topic> <topic>2‑Photon microscopy</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619001-2</identifier> <identifier type="oldLupId">4434858</identifier> <part> <detail type="volume"> <number>2014:72</number> </detail> <extent unit="pages"> <total>134</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-04T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f5d30aa8-9496-4582-a59d-00f0fc7a4ec2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:50+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:50+02:00</recordDateApproved> </recordInfo> </mods>

It is a preventable and treatable disease. Smoking is the most commonly encountered risk factor for COPD and the habit now unfortunately starts at earlier ages than before. There is a strong necessity to diagnose COPD in early stages before symptoms present themselves. MRI with hyperpolarized 3He using diffusion weighted sequences has the potential to detect and quantify parenchyma destruction in emphysema, the main manifestation of COPD.&lt;br/&gt;&lt;br&gt; Study I investigated the short-term reproducibility of the method and the volume of gas required to obtain suitable results in normal volunteers and patients with COPD. The mean ADC measurement was highly reproducible, sensitive to small differences in alveolar size and clearly separated volunteers and patients. There was a dependency of inhaled volume.&lt;br/&gt;&lt;br&gt; Study II investigated the long-term reproducibility, age-dependency and anatomical variation of ADC in normal volunteers. The mean ADC measurement was highly reproducible over one year. There was correlation between age and mean ADC. There was a difference in mean ADC between anterior and posterior parts of the lungs in supine position probably depending on the gravity. &lt;br/&gt;&lt;br&gt; Study III compared hyperpolarized 3He-diffusion MRI technique with MSCT and different PFT:s. The mean ADC correlated well with emphysema index and 15th percentile from CT. DL,CO is the PFT best correlating with emphysema grade and the correlation was higher between 3He -MRI and DL,CO than between CT and DL,CO.&lt;br/&gt;&lt;br&gt; Study IV investigated if hyperpolarized 3He-diffusion MRI technique was sensitive enough to detect emphysema progress over a year. The mean ADC did not detect changes over 12 months. An ad hoc analysis performed afterwards using a textural analysis, lacunarity analysis, showed progress in patients with COPD who smoked at the beginning of the study, but not in patients who had stopped smoking earlier.&lt;br/&gt;&lt;br&gt; In conclusion, hyperpolarized 3He-diffusion MRI technique is a robust method, highly reproducible over a short and a longer period of time. The method has been validated with standard methods, pulmonary function tests and CT. The combination of MRI, hyperpolarized gases, and a proper textural analysis of the data will likely provide a powerful investigative tool at least in research settings for understanding the pathophysiology of emphysema and evaluation of therapies designed to alter the course of disease even if economic obstacles may prohibit a more widespread clinical use.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7de1c675-1a91-4b69-b3dd-1ebcdc6b9921</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="THESIS_med_dok_data_blad.pdf">https://portal.research.lu.se/files/3105475/1267627.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1315370</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Diagnostic Radiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Helium</topic> <topic>Hyperpolarized</topic> <topic>MRI</topic> <topic>ADC</topic> <topic>Emphysema</topic> </subject> <subject authority="lup"> <topic>Radiology and Medical Imaging</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-80-4</identifier> <identifier type="oldLupId">1267606</identifier> <part> <detail type="volume"> <number>2008:128</number> </detail> <extent unit="pages"> <total>106</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-18T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>7de1c675-1a91-4b69-b3dd-1ebcdc6b9921</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:53+02:00</recordDateApproved> </recordInfo> </mods>

We developed two new methods for&lt;br/&gt;&lt;br&gt; HPV-testing with genotyping: A high-throughput HPV genotyping method that uses&lt;br/&gt;&lt;br&gt; mass spectrometry for detection of the products of type-specific mass extend&lt;br/&gt;&lt;br&gt; reactions, and a method with particularly sensitive detection of a broad spectrum of&lt;br/&gt;&lt;br&gt; HPV-types, also in the case of multiple infections, that uses type-specific probes&lt;br/&gt;&lt;br&gt; coupled to fluorescent beads for detection on the Luminex platform.&lt;br/&gt;&lt;br&gt; The utility of HPV-testing was evaluated in 3 different studies:&lt;br/&gt;&lt;br&gt; A general primer PCR-based genotyping method and the commercial Hybrid Capture&lt;br/&gt;&lt;br&gt; (HCII) assay were compared for sensitivity and specificity for detection of CIN in&lt;br/&gt;&lt;br&gt; secondary screening and in follow-up after treatment for cervical dysplasia. The&lt;br/&gt;&lt;br&gt; sensitivities were high for both methods, although somewhat higher for the PCR&lt;br/&gt;&lt;br&gt; method, but the concordance between the methods was substantial.&lt;br/&gt;&lt;br&gt; The performance of HPV-genotyping for prediction of recurrence after treatment for&lt;br/&gt;&lt;br&gt; CIN was compared to that of cytology. Only HPV-genotyping could predict all cases&lt;br/&gt;&lt;br&gt; of CIN grade II or worse in histopathology, and all cases of CIN I or worse in&lt;br/&gt;&lt;br&gt; cytology during follow-up had persistence of HPV.&lt;br/&gt;&lt;br&gt; The applicability of HPV-genotyping was also evaluated in a secondary screening&lt;br/&gt;&lt;br&gt; setting. Different high-risk HPV types had substantial differences in risk for presence&lt;br/&gt;&lt;br&gt; of CIN III or worse among women with ASCUS and CIN I in cytology, suggesting&lt;br/&gt;&lt;br&gt; that HPV typing could be useful for further optimization of ASCUS/CIN I triaging&lt;br/&gt;&lt;br&gt; strategies.&lt;br/&gt;&lt;br&gt; In summary, 2 HPV-genotyping methods with different applicability have been&lt;br/&gt;&lt;br&gt; developed and validated. We also conclude that HPV genotyping is useful both in&lt;br/&gt;&lt;br&gt; secondary screening as well as in follow-up after treatment for CIN.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a18ba084-4c28-438e-9eb0-e88bb34c74ca</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_A_Soderlund_Strand.pdf">https://portal.research.lu.se/files/3105679/1268128.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">808678</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Medical Microbiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-69-9</identifier> <identifier type="oldLupId">1268127</identifier> <part> <detail type="volume"> <number>2008:116</number> </detail> <extent unit="pages"> <total>156</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-10T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>a18ba084-4c28-438e-9eb0-e88bb34c74ca</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:00:56+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:00:56+02:00</recordDateApproved> </recordInfo> </mods>

The aim of the study is to explore and visualize the experiences of HIV-positive Swazi Christians in church and society, as well as an attempt to explain these experiences with the contributions of key informants and the Swazi tradition. The study is based upon focus group interviews with twelve women and eight men. The study focuses the everyday experiences of HIV-positive Christian Swazis in church and society, and the fifteen key informant interviews are important resources in explaining and elaborating the context within which these experiences have been formed. The sociological question of the study is: How do HIV-positive Swazi Christians perceive their situation in church and society? A problem, which is analyzed by way of Bourdieu’s theory on symbolic power, and the act of operation, is realized through the symbolic principles HIV-related stigmatization and male dominance, as well as silence and denial strategies. &lt;br/&gt;&lt;br&gt; My analysis discusses the struggle within the HIV-field between two discourses: the biomedical discourse and the socio-religious discourse. I discuss how HIV seems to represent, or even constitute, the crisis that has broken doxa, how the struggle in the HIV-field is about definitions of HIV, and also how the distribution of the HIV-field’s legitimate resources into symbolic and economic capital is of decisive significance to the field. The struggle is between a bio-medical discourse, whose agents are mainly represented by INGO’s, and a socio-religious discourse, whose agents are composed of local cultural, political and religious representatives. HIV as a crisis raises questions about male dominance, something that I have discussed. Through the empirical material, I have indicated the importance of the exchange of symbolic capital as a basis for social order, and how the exchange, as well as the illusion of the naturalness of the male dominance’s and the common action are present within both discourses and produce euphemisms of symbolic dominance and inequality in relation to male dominance. The empirical material is composed of joint descriptions of experiences concerning cultural principles and the Bible as authorities in order to legitimate male dominance, together with experiences concerning the reproduction of male dominance within the practices of institutions. I analyze how the somatization of the gendered power relations and the ideology about sexuality and gender, serve the dominating group of adult men and thereby render the control of women’s sexuality possible. Orthodoxy’s possession of symbolic capital constitutes a condition for dominance, forms the basis of the ideology that legitimates separation categories, and also provides a capital of trust, which gives the legitimacy to speak. The collective expectations and the habitus of individuals result in a situation where no one chooses to disclose due to the risk of being separated from the collective. The ideology and the intentional action demand silence from the collective and a mis-recognition in order to take away men’s responsibility for HIV. The empirical material shows that the publicly communicated ecclesiological truth about HIV is a euphemism by the churches that HIV-positive people are prostitute and promiscuous women who are not members of the congregation, and therefore HIV does not exist in the church. I have tried to demonstrate how recognition and acknowledgement can make HIV visible.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/127873ea-7679-421c-8e3c-157bc5cbd174</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>HIV</topic> <topic>AIDS</topic> <topic>gender</topic> <topic>churches</topic> <topic>traditional religion</topic> <topic>focus groups</topic> <topic>Swaziland</topic> <topic>southern Africa</topic> <topic>symbolic power</topic> <topic>symbolic violence</topic> <topic>male dominance</topic> <topic>HIV-related stigmatization</topic> <topic>silence</topic> <topic>denial</topic> <topic>mis-recognition.</topic> </subject> <subject authority="lup"> <topic>Philosophy, Ethics and Religion</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in Sociology of Religion</title> </titleInfo> <identifier type="issn">1651-4432</identifier> <identifier type="isbn">91-974760-7-2</identifier> <identifier type="oldLupId">2438536</identifier> <part> <detail type="volume"> <number>10</number> </detail> <extent unit="pages"> <total>366</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-05-09T15:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>127873ea-7679-421c-8e3c-157bc5cbd174</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:02+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:02+02:00</recordDateApproved> </recordInfo> </mods>

As a part of the global justice movement that emerged in the 1990s, the organisation Attac Sweden related to a larger process. Attac Sweden was also central in debates about globalisation in the Swedish political context around the years 2000 and 2001. This study is based both on ethnographic data, such as observations and interviews with active members of Attac Sweden, and archival data from the organisation such as internal documents. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The chapters of this study cover the emergence of the organisation in France as well as the development in the Swedish political context. In particular, the general critique against neoliberal globalisation and the possible solutions that Attac lobbies for are examined. These general ideas were also brought forward by Attac in Sweden. An initial phase of public interest was, however, followed by decline. The ethnographic chapters examine Attac Sweden’s way of organising and of acting politically on global issues. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Being part of a larger movement has shaped the way that Attac Sweden has chosen to organise and how political action has been negotiated. In the organisational structure of Attac Sweden this has meant that ideas of participatory democracy have been elaborated. The activists interviewed also reflected on the difficulties in translating global political issues into local concerns, and put forward knowledge and popular education as both part of a struggle and as part of a participatory democratic ideal. In conclusion, knowledge and democracy are related to a wider civil society debate.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/df240431-1561-49b6-b703-0cd7eb6293ce</url> </location> </relatedItem> <originInfo> <publisher>Department of Sociology, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>globalisation</topic> <topic>global justice movement.</topic> <topic>knowledge</topic> <topic>social movement</topic> <topic>Sweden</topic> <topic>Attac</topic> <topic>anthropology</topic> </subject> <subject authority="lup"> <topic>Social Anthropology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Monographs in Social Anthropology</title> </titleInfo> <identifier type="issn">1101-9948</identifier> <identifier type="isbn">91-7267-317-6</identifier> <identifier type="oldLupId">1600537</identifier> <part> <detail type="volume"> <number>20</number> </detail> <extent unit="pages"> <total>146</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-29T14:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>df240431-1561-49b6-b703-0cd7eb6293ce</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:11+02:00</recordDateApproved> </recordInfo> </mods>

Air pollution has become an acknowledged risk factor for stroke, especially for acute effects. There is less support for effects by chronic exposure due to the methodological challenges inherent in such studies. Such challenges can regard missing individual level data or residual confounding and can partly be overcome by employing two-phase methods. The general idea with such methods is to incorporate study subjects with partly missing data into the analysis. The main aims in this work were to investigate if air pollution increase stroke risk in Scania (Sweden), where pollution levels are rather low, and to investigate the performance of different two-phase methods. &lt;br/&gt;&lt;br&gt; Methods: Nitrogen oxides (NOx) concentrations were modelled with high resolution. Data from the National Stroke Register (Riks-stroke) were obtained on hospital admissions for ischemic and hemorrhagic stroke during the years 2001 to 2006. The association between annual mean levels of NOx (as a marker for long-term exposure to air pollution) and ischemic stroke was studied in a two-phase case-control design. The short-term association between daily levels of inhalable particulate air pollution (PM10), ozone, NOx and temperature and the number of strokes occurring each day was studied with time series methods. The performance of several different two-phase methods was compared in a simulated case-control study.&lt;br/&gt;&lt;br&gt; Results: No association between annual mean NOx and ischemic stroke was observed. Regarding short-term effects, high levels of PM10 increased the risk of ischemic stroke the next day, whereas high levels of temperature decreased the risk the next day. For hemorrhagic strokes, a similar, but less precise pattern was observed. Two-phase methods seemed to benefit from incorporating group-level data on exposure. The method which was most suitable for incorporating such data could be generalised to polytomous exposure categories and to include confounding factors.&lt;br/&gt;&lt;br&gt; Conclusions: No evidence for long-term exposure to air pollution to increase ischemic stroke risk in Scania was observed. Short-terms effects by PM10 were documented, contributing to evidence for risk increases even in low-level areas. The role of temperature should be investigated further. The use of two-phase methods was illustrated in both a methodologial study and an empirical study.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/319644d0-7f88-4c5e-9ab4-c098b80cbff2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="OudinKappa.pdf">https://portal.research.lu.se/files/3110377/1510695.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1786827</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Occupational and Environmental Medicine</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Long-term effects</topic> <topic>Two-phase methods</topic> <topic>Hemorrhagic stroke</topic> <topic>Ischemic stroke</topic> <topic>Short-term effects</topic> <topic>Hospital admissions</topic> <topic>Air Pollution</topic> </subject> <subject authority="lup"> <topic>Occupational Health and Environmental Health</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-09-2</identifier> <identifier type="oldLupId">1510693</identifier> <part> <detail type="volume"> <number>2009:120</number> </detail> <extent unit="pages"> <total>162</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-12-17T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>319644d0-7f88-4c5e-9ab4-c098b80cbff2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:20+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:20+02:00</recordDateApproved> </recordInfo> </mods>

The primary measures introduced to eliminate undesirable differences in medical care are the introduction of medical guidelines and economical incentives that rewards the desired behaviour.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Practice variation in primary care can be seen on different hierarchically organised levels (e.g. patient, physician, health care center (HCC)) and Multilevel Regression analysis techniques (MLRA) offer a suitable tool to analyse these kinds of data. Data extracted from computerised medical records are ideal for studying practice variation as they often comprise information from several levels. In the region of Skaraborg in Sweden a new database, the Skaraborg Primary care database (SPCD), comprising information extracted form the computerised medical records of all public health care centres has recently been established.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The overall aims of this thesis were to examine the usefulness and quality of the SPCD database for research and to study practice variation in some important areas such as diagnosis registration, laboratory analysis ordering and prescriptions. Furthermore, the influence of changes in the economic incentives on physician’s clinical behaviour was investigated. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Material and Methods: In all studies data from the SPCD comprising data on individual patients from all public health care centres was used. The registration of diagnoses in the SPCD was validated by comparing the occurrence of recorded diagnosis in the diagnosis register of the database with the free text part of the patient medical records for a randomly selected sample of patients. Multilevel logistic regression analysis was used to investigate practice variation in prescribing and laboratory test ordering, focusing on measures of both frequency and variance. The effects of changes in economic incentives for diagnosis coding and prescribing were examined by comparing multilevel analysis results before and after implementation of the economic incentives. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Results and Conclusions: The frequency of registration of ICD codes varied between diagnoses but also between physicians and HCCs. Different diagnoses need to be validated separately.&lt;br/&gt;&lt;br&gt; The occurrence of practice variation was demonstrated both in laboratory test ordering where the physician level was the most important level and in prescribing where physician and HCC levels were equally important in explaining the observed variation.&lt;br/&gt;&lt;br&gt; A positive effect in adherence to prescribing guidelines was demonstrated after the introduction of a decentralised drug budget.&lt;br/&gt;&lt;br&gt; The introduction of a strong economic incentive for ICD coding showed the expected rise in coding rates and decline in variation, directly affecting the diagnoses register of the research database.&lt;br/&gt;&lt;br&gt; Changes in the healthcare process will have a direct impact on the research database. Knowledge about the local health care processes is essential when interpreting database data.&lt;br/&gt;&lt;br&gt; The SPCD seems as a good complement to previously established databases and quality registers, offering new possibilities when studying primary care.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; ”Practice variation”&lt;br/&gt;&lt;br&gt; I den kliniska vardagen ser man ofta slående variationer i handläggningsrutiner mellan läkare och vårdcentraler utan att detta kan förklaras av skillnader i sjuklighet hos patienterna. Dessa oförklarade skillnader benämns ”practice variation” och beror på lokalt förankrade rutiner ofta etablerade sedan länge. De är sällan vetenskapligt underbyggda utan kan snarare ses som ett uttryck för enskilda doktorers skiftande kliniska erfarenheter eller som orsakade av att yttre faktorer såsom varierande ersättningssystem, bemanning eller resurser. Ofta är denna variation oönskad och kan finnas på olika nivåer i sjukvårdshierarkin (sjukvårdsområden, vårdcentraler eller doktorer). Förekomst av variation i handläggning väcker frågor om över- och underbehandling men även om brister i jämställdhet i vården. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ett sätt att minska oönskad ”practice variation” är införandet av medicinska styrdokument såsom vårdprogram och läkemedelskommittéernas förskrivnings-rekommendationer. Det har dock visat sig att det ofta krävs mer än riktlinjer för att åstadkomma förändringar inom sjukvården. Ett effektivt styrmedel i dessa fall är införandet av olika ekonomiska incitament.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Flernivåanalyser&lt;br/&gt;&lt;br&gt; En gängse metod för jämförelser av kvalitet i vården är att t.ex. jämföra antal vårddagar, frekvenser av förskrivna läkemedel eller olika typer av behandlingar mellan vårdinrättningar (Öppna jämförelser). Slutsatserna av sådana jämförelser kan bli felaktiga eftersom man inte tar hänsyn till att bakomliggande faktorer kan påverka resultatet. Ett alternativt sätt att göra jämförelserna på är att använda flernivåanalyser (Multilevel regression analysis, MLRA). Denna teknik möjliggör att faktorer från olika nivåer (t.ex. vårdcentral (bemanning), läkare (kön, ålder, erfarenhet) eller patient (kön, ålder sjuklighet) kan inkluderas i samma analys. Dessa analyser möjliggör också att den variation som finns kan fördelas på de olika nivåerna. Man kan på så sätt avgöra vilken nivå som bäst lämpar sig för påverkan för att minska oönskad variationen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Data från datoriserade patientjournaler lämpar sig mycket väl för att studera denna variation. Den avspeglar direkt vad som gjorts i det kliniska mötet mellan patient och vårdgivare på individnivå och innehåller ofta data på såväl vårdcentral- och läkarnivå som patientnivå.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Skaraborg och Skaraborgs primärvårds databas (SPCD)&lt;br/&gt;&lt;br&gt; Skaraborg, som tidigare var ett eget län, är sedan 1999 en del av Västra Götalands- regionen och har ungefär 250 000 invånare. Inom primärvården i Skaraborg har den offentliga vården varit klart dominerande, och sedan slutet av 1990-talet använder alla 22 offentliga vårdcentraler samma journalsystem, ProfDoc Journal III som gjort det möjligt att konstruera en forskningsdatabas, The Skaraborg Primary Care Database (SPCD). SPCD består av separata datafiler från varje vårdcentral med information om registrerade diagnoser, läkemedelsförskrivningar, laboratorieprover, åtgärder, sjukskrivningar, remisser och patientkontakter på individnivå. Vid extrahering av data från vårdcentralernas datajournaler sker en avidentifiering av patient och vårdgivare men specifika löpnummer möjliggör kopplingar inom databasen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En primärvård i förändring&lt;br/&gt;&lt;br&gt; Det har skett flera förändringar av organisatorisk och ekonomisk natur inom primärvården i Skaraborg under senaste decenniet. Vårdcentralsbudgeten de-centraliserades år 2003 och 2009 infördes vårdvalssystemet ”Västra Götalands Primärvård” (VGPV) vilket bl.a. innebar ett ersättningssystem byggt på antal listade patienter och deras vårdtyngd beräknat på diagnoser registrerade i patientjournalen.&lt;br/&gt;&lt;br&gt; Eftersom SPCD är en databas som tar data från den kliniska verksamheten och innehåller data från samtliga offentliga vårdcentraler i Skaraborg utan selektion, finns ett särskilt intresse att använda dessa data för studier för att öka vårdkvaliteten. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Syftet med denna avhandling är att:&lt;br/&gt;&lt;br&gt; Studera SPCD:s kvalitet för forskningsändamål och hur dess innehåll påverkas av förändringar i sjukvårdsorganisationen.&lt;br/&gt;&lt;br&gt; Studera “practice variation” i diagnosregistrering, beställning av plasma kalcium (P-Ca) analyser och läkemedelsförskrivning.&lt;br/&gt;&lt;br&gt; Studera lämplig nivå (vårdcentral, läkare, patient) att påverka för att minska en oönskad variation i handläggning. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Till de fyra delprojekt i denna avhandling har datamängder från SPCD använts. I studie I kontrollerades registreringen av diagnoser och läkemedel för diagnos-grupperna högt blodtryck, diabetes, kranskärlssjukdom och hjärtsvikt genom att jämföra innehållet i SPCD:s diagnosregister med journaltexten från 1 200 slumpvis utvalda patienter (validering). I de övriga studierna användes MLRA-teknik för att studera ”practice variation” i beställning av laboratorieanalyser (studie II), för-ändring i förskrivning av blodfettssänkande läkemedel efter den decentraliserade budgeten (studie III) och förändring av diagnosregistrering efter införande av VGPV (studie IV). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Resultat&lt;br/&gt;&lt;br&gt; Diagnosregistreringsfrekvensen visade sig variera mellan diagnoser, med höga frekvenser för diabetes och hypertoni, men även mellan läkare och vårdcentraler. Detta medför att olika diagnoser måste valideras och värderas var för sig. Registreringen av förskrivna läkemedel visade sig vara god (studie I). &lt;br/&gt;&lt;br&gt; De ekonomiska incitament som infördes 2009 visade sig höja frekvensen patienter med registrerad hypertoni och cancerdiagnos till det dubbla. Detta beror sannolikt på ändrade registreringsrutiner. Detta har haft en direkt effekt på innehållet i SPCD, vilket gör att kunskap om förhållandena i det lokala sjukvårdsområdet krävs när man studerar denna typ av data (studie IV).&lt;br/&gt;&lt;br&gt; Vidare påvisades ”practice variation” vid beställning av P-Ca analyser, där läkarnivån var viktigast (studie II), och vid förskrivning av blodfettssänkande läkemedel där läkar- och vårdcentralsnivåerna var lika viktiga för att förklara de observerade skillnaderna och att de förändrade ekonomiska villkoren ökade följsamheten till rekommendationerna (studie III).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Konklusion och framtidperspektiv&lt;br/&gt;&lt;br&gt; De två budgetförändringar som studerades visade sig påverka doktorernas beteende. Ekonomiska styrsystem förefaller således potenta när det gäller att åstadkomma förändringar inom sjukvården. De måste därför vara väl genomtänkta före införandet, för att undvika oönskade bieffekter. SPCD förefaller utgöra ett bra komplement till tidigare kvalitetsregister och internationella databaser för forskningsändamål. Den kan dessutom länkas till nationella databaser såsom läkemedelsregistret, SCB och Socialstyrelsens vård-dataregister.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f84adef7-9220-47b9-8921-36770c9c7ef7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Per_Hjerpe_KAPPA.pdf">https://portal.research.lu.se/files/3112037/2117464.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">502516</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Unit of Social Epidemiology</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Medical records systems (computerized)</topic> <topic>Databases factual</topic> <topic>Reimbursement incentive</topic> <topic>Physician&apos;s Practice Patterns</topic> <topic>Multilevel analysis</topic> <topic>Primary health care</topic> </subject> <subject authority="lup"> <topic>Occupational Health and Environmental Health</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-33-8</identifier> <identifier type="oldLupId">2117277</identifier> <part> <detail type="volume"> <number>2011:83</number> </detail> <extent unit="pages"> <total>142</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-09-29T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f84adef7-9220-47b9-8921-36770c9c7ef7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:34+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:34+02:00</recordDateApproved> </recordInfo> </mods>

It is an autoimmune disease with many autoimmune markers, where the zinc transporter 8 autoantibody (ZnT8A) is the most recent autoantibody discovered. The most important genetic susceptibility towards type 1 diabetes is found within the HLA-region on chromosome 6. We showed that all three ZnT8A are common among children and adolescents at type 1 diabetes diagnosis and that 3.4% of the children in Sweden displayed only ZnT8A at diagnosis. Only 7% of the Swedish children were autoantibody negative at diagnosis. Additionally, 0.3% of type 1 diabetes patients in Sweden had an isolated positivity for the islet cell cytoplasm autoantibodies (ICA). This is an autoantibody with an unspecified reaction pattern to most of the other antigens involved in autoantibody formation in type 1 diabetes. The fact that children can still be diagnosed with ICA as the only autoantibody suggests that another yet unidentified autoantigen or autoantigens may contribute to ICA and the search for additional autoantigens should continue. We propose that the glutamine variant of the ZnT8A (ZnT8QA) is not cost effective as a diagnostic marker, as it was found as a single islet autoantibody only in one patient among 3851 analyzed children. However, comparing young healthy children with multiple autoantibodies with normal and impaired glucose metabolism we found that significantly more children with impaired glucose metabolism were positive for ZnT8QA compared to children with normal glucose metabolism. Hence, the ZnT8QA analysis is important in screening of populations for type 1 diabetes risk and for secondary prevention studies. All variants of ZnT8A were positively associated with either HLA DQA1-B1*X-0604 (DQ6.4) or HLA DQA1*0301-DQB1*0302 (DQ8) but dominantly negative with HLA DQA1*0501-DQB1*0201 (DQ2). The association between DQ 6.4 and all three ZnT8A may be related to ZnT8 antigen-presentation by the DQ6.4 heterodimer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a3c3a368-ef87-45b1-b612-22823f11b3ea</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappan_CA_MT_121025.pdf">https://portal.research.lu.se/files/3115269/3166269.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">700492</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Paper_I.pdf">https://portal.research.lu.se/files/3115271/3166270.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">148639</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Paper_II.pdf">https://portal.research.lu.se/files/3115273/3166271.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">660258</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Cecilia_K_Andersson_omslags-prov_genomskinlig_bild_1_.pdf">https://portal.research.lu.se/files/3115275/3166272.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">569667</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Paediatric Endocrinology Research Group</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Type 1 diabetes</topic> <topic>Zinc transporter</topic> <topic>ZnT8 autoantibodies</topic> <topic>HLA</topic> <topic>islet cell autoantibodies</topic> <topic>GAD65 autoantibodies</topic> <topic>IA-2 autoantibodies</topic> <topic>insulin autoantibodies</topic> <topic>glucose tolerance</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> <topic>Pediatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-53-1</identifier> <identifier type="oldLupId">3166264</identifier> <part> <detail type="volume"> <number>2012:90</number> </detail> <extent unit="pages"> <total>101</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-11-30T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>a3c3a368-ef87-45b1-b612-22823f11b3ea</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:39+02:00</recordDateApproved> </recordInfo> </mods>

With a growing awareness about serious damages to the environment and human health from a lack of safe treatment and recycling of WEEE, there has been a search for policy responses in several of these countries. This research finds that extended producer responsibility (EPR), a policy principle that underpins WEEE programmes in many OECD countries, can help solve the WEEE problem in non-OECD countries by putting the onus on the producers to ensure environmentally sound management of their end-of-life products and make improvements in their product systems, including change in product design. Although there are challenges to the implementation of EPR in emerging and developing economies, notably the problem of free riders and the competition for materials from the polluting recycling sector, they are manageable. In addition, opportunities exist that can facilitate the development of EPR-based solutions, such as the relatively small stock of historical WEEE and manufacturers that have the commitment and experiences with the principle. What is needed to realise this potential is for the policy-makers to create a policy framework that allows and encourages product and system innovations from the producers.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; El-avfall (avfall från elektriska och elektroniska produkter) har under det senaste årtiondet blivit ett växande miljöproblem också i de mindre rika länderna (icke-OECD länder). Informell återvinning i u-länder har lett till att giftiga ämnen, som t.ex. bly och kvicksilver från tv-apparater, PVC från sladdar och bromerade flamskyddsmedel från plastkomponenter, har läckt ut i naturen och förgiftat folk. Först antogs att detta miljöfarliga el-avfall var exporterat från Västvärlden i strid mot Baselkonventionen, men nyare studier har visat att andelen el-avfall från inhemsk konsumtion har ökat markant i många växande ekonomier i tredje världen. Som ett resultat är det flera av dessa länder som nu utvecklar system och lagstiftning för hanteringen av el-avfall.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Denna avhandling föreslår att icke-OECD länder tar lärdom av erfarenheterna från OECD-länderna och på ett förebyggande sätt och genom en helhetssyn tar sig an problematiken. Många OECD-länder ger ansvaret till producenterna för att avfallet från deras varor tas om hand när de är uttjänta, d.v.s. de har infört producentansvar. Genom att producenterna blir ansvariga så skapas incitament för dem att förbättra varornas återvinningsegenskaper och dessutom att förbättra andra delar av produktsystemet. Förutom att utveckla förbättrad avfallshanteringsteknik och -metoder, så kan varans design ändras så att avfallshanteringen underlättas, t.ex. genom att minska andelen giftiga ämnen som är inbyggda i material och komponenter. Många länder, inom och utom OECD, har begränsat användningen av bly, kvicksilver, kadmium, sexvärt krom, polybromerade bifenyler (PBB) och polybromerade difenyletrar (PBDE) i nya elektriska och elektroniska produkter. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Erfarenheterna från OECD visar att producenter kan bli ansvariga för el-avfall på flera olika sätt. I Kalifornien har man en återvinningsavgift vid försäljning av nya tv-apparater och datorer. Delstatsregeringen använder sedan pengarna för att betala för insamling och återvinning av elektronikavfallet. Andra delstater i USA beslutar varje år om den mängd el-avfall som varje tillverkare måste samla in och återanvända eller återvinna. I dessa delstater får producenterna sedan bestämma hur systemet ska se under förutsättning att det är kostnadsfritt för hushållen. I Europa organiserar sig producenterna ofta i gemensamma producentansvarsbolag, som på deras uppdrag tar hand om insamling och återvinning kostnadsfritt för hushållen. I Japan lämnas uttjänta apparater till affärerna och sorteras sedan efter tillverkare. De stora tillverkarna har sedan sina egna återvinningsanläggningar. Det japanska systemet har visat sig vara effektivt när det gäller att få tillverkarna att lära sig mer om återvinning av deras varor och stimulerar designförbättringar. Japanska hushåll måste dock betala för insamling och återvinning när de returnerar den uttjänta varan. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Avhandlingen visar att det finns förutsättningar för att tillämpa producentansvar för att hantera el-avfall i icke-OECD länder. En omständighet är att mängden el-avfall fortfarande är relativt begränsad i dessa länder. Det betyder att man fortfarande kan genomföra effektiva förebyggande återgärder för den framtida växande mängden el-avfall, t.ex. kräva att tillverkarna fasar ut användningen av giftiga ämnen och införa finansiella återvinningsgarantier för nya varor innan de sprids på marknaden. En annan faktor som gynnar dessa länder är att många tillverkare av informations- och kommunikationsteknik har som intern företagspolicy att utveckla system för omhändertagande av uttjänta varor. Sådana företag är ofta multinationella företag med lång erfarenhet av producentansvar från OECD-länderna. Om importörer görs ansvariga för att betala återvinningsavgifter för importerade secondhand varor så kommer de att ha svårare att kringgå Baselkonventionens förbud för import av el-avfall genom att deklarera sådant avfall som användbara secondhand varor. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Även om det finns utmaningar när det gäller att införa producentansvar, bl.a. svårigheter att identifiera producenter för falskmärkta och omärkta varor samt att konkurrera med den förorenande informella återvinningssektorn om återvinningsbara material, så är dessa utmaningar hanterbara. Stora företag som förser tillverkare med komponenter för omärkta varor, t.ex. en del komponentbyggda datorer, kan göras ansvariga istället för att jaga små verkstäder som monterar ihop sådana varor. Av stor vikt är att de avgifter som samlas in kan användas för att stödja de återvinningsanläggningar som följer lagar och regler genom att de används för att utjämna kostnaderna för dem i förhållande till den informella sektorn och därigenom omdirigera flödet av el-avfall till dessa. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Baserat på forskningen så uppmanar avhandlingen politikerna i icke-OECD länder att gripa möjligheten att tas sig an de utmaningar som finns genom att utnyttja den fulla potential i producentansvaret. De har förmånen att kunna lära av framgångar och misstag från OECD-länderna. Även om det inte är en enkel uppgift, så är det klart möjligt att baserat på dessa erfarenheter och kunskap om det egna landet konstruera och driva ett program som belönar de producenter som utvecklar sina varor så att miljökvaliteten höjs.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Waste electrical and electronic equipment (WEEE) has been a growing environmental problem among countries outside the Organisation for Economic Co-operation and Development (OECD) since the turn of the century. Backyard recycling in these countries has released hazardous substances such as lead and mercury in TV panels, PVC in wire coating, or brominated flame retardants in plastics into the environment and, eventually, into human bodies. While it was believed that most of the hazardous waste came from the illegal imports that breached the Basel Convention, new studies have shown that the amount of local WEEE is increasing sharply in emerging and developing economies adding to the already serious problem. Several major non-OECD countries are now developing policies, including a legal framework, from the management of WEEE.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis suggests that non-OECD countries should learn from the experiences in OECD countries to take actions in an integrative and preventive manner. Many OECD countries have asked the producers of the products to be responsible for the management of their obsolete products once the users discard them. This policy approach is called “extended producer responsibility” (EPR). By making a producer responsible for the end-of-life management, EPR can give incentives to him/her to improve not only the waste management per se but also other parts of the product system. In addition to develop new waste treatment methods and technologies, the producer may redesign the products in a way that make waste management easier, such as reducing the amount of hazardous substances in the products. As a matter of fact, many countries, OECD and non-OECD, have restricted the use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ether in new electrical and electronic products.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The experiences in OECD countries show that the producers can be made responsible for the management of WEEE in various ways. The State of California, for example, levies recycling fees on the sales of TVs and computers. The State then uses the fees to pay the bill for the collection and recycling of the electronic waste (e-waste). Some other states in the United States of America set the quantity of e-waste that each producer has to collect and reuse or recycle in each year. These states normally leave the operational details to the producers as long as they take the obsolete products back from the households without charging handling fees. In Europe, producers often come together and form collective bodies, called producer responsibility organisations (PROs). Producers then pay the PROs to carry out the collection and recycling work, including the free take-back of WEEE, on their behalf. The competition between the collectives in several European countries has helped keeping the compliance costs low for the producers. In Japan used home appliances are returned to retailers and then sorted by the brands of their makers. Major Japanese manufacturers set up treatment plants to recycle their own products. The physical arrangement in Japan has proved to be effective in engaging the manufacturers in learning about the recycling of their products and stimulating product redesign. However, Japanese households still have to pay the bill for the collection and recycling of home appliances.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis finds that there are opportunities in applying EPR to the management of WEEE in the context of non-OECD countries. First, the level of WEEE generation remains rather low in emerging and developing economies. This will allow non-OECD countries to take preventive actions for the growing amount of WEEE in the future, such as asking the producers to phase out hazardous substances and provide recycling guarantees for new products they put on the market. Second, many manufacturers of information and communication technologies (ICT) are committed to develop end-of-life solutions for their products. Most of them are multinational corporations that have years of experiences from the implementation of EPR in OECD countries. In addition, having the importers responsible, for example by paying recycling fees for second-hand products they import, will discourage them to break the Basel convention by faultily declaring WEEE as reusable products.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Although there are challenges to the implementation of EPR, including the difficulty to identify the producers of counterfeit and no-brand products and the competition for recyclable materials from the polluting recycling sector, these challenges are manageable. Large companies that supply components for assembled products, such as “white-box” computers, can be made the responsible producers in an EPR programme instead of trying to catch small assemblers. More importantly, the resources from the programme can be used to level the game for treatment facilities that operate legally in the competition for recyclables with the informal sector. This will help diverting the flows of WEEE from the polluting backyard recycling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Based on this analysis, this thesis urges policy actors in non-OECD countries to grasp the opportunities and address the challenges to unleash the full potential of EPR. They have the privilege to learn from the successes and the mistakes of OECD countries. Although not a simple task, it is very possible with these policy lessons and the understanding about the context of one’s country to design and operate a creditable programme that rewards the responsible producers who come up with innovations that improve the environmental performance of their products.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/68872bc7-cf62-4718-a2ec-4b4c40257d0f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="2011_Manomaivibool_Advancing_the_frontier_of_EPR.pdf">https://portal.research.lu.se/files/3115417/2156616.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2683991</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>International Institute for Industrial Environmental Economics, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Extended Producer Responsibility (EPR)</topic> <topic>Waste Electrical and Electronic Equipment (WEEE)</topic> <topic>Electronic Waste (E-waste)</topic> <topic>Policy Transfer</topic> <topic>Waste Policy</topic> <topic>Product Policy</topic> <topic>Recycling</topic> </subject> <subject authority="lup"> <topic>Other Social Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>IIIEE Dissertation</title> </titleInfo> <identifier type="issn">1402-3016</identifier> <identifier type="isbn">978-91-88902-73-3</identifier> <identifier type="oldLupId">2062478</identifier> <part> <detail type="volume"> <number>2011:1</number> </detail> <extent unit="pages"> <total>256</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-09-09T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>68872bc7-cf62-4718-a2ec-4b4c40257d0f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:42+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:42+02:00</recordDateApproved> </recordInfo> </mods>

Given that uncertainty is explicitly allowed to influence&lt;br/&gt;&lt;br&gt; our view of what the future holds for us, most ex ante analyses of challenges for&lt;br/&gt;&lt;br&gt; sustainable development can be viewed as analysing risk. Many frameworks for&lt;br/&gt;&lt;br&gt; analysing risk exist today, but analysing risk for sustainable development entails&lt;br/&gt;&lt;br&gt; different requirements. By applying a combination of traditional science and design&lt;br/&gt;&lt;br&gt; science, this thesis presents six such requirements, informed by available theory and&lt;br/&gt;&lt;br&gt; new empirical studies. The thesis also presents six criteria for scientifically developing&lt;br/&gt;&lt;br&gt; frameworks for analysing risk for sustainable development.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Hållbar utveckling ställer krav på nya riskanalysmetoder&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hållbar utveckling bygger på vår förmåga att fatta beslut i dag som avgör vår morgondag. Det låter enkelt, men är en av mänsklighetens största utmaningar då mycket i vår värld hänger samman och framtiden är full av osäkerheter. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Givet att osäkerhet tillåts påverka vår syn på vad framtiden har i sitt sköte, kan de flesta framåtblickande analyser av utmaningar för hållbar utveckling anses vara riskanalyser. Det existerar många sätt att analysera risk idag, men att analysera risk för hållbar samhällsutveckling innebär enligt en doktorsavhandling vid Lund universitet minst sex särskilda krav.&lt;br/&gt;&lt;br&gt; Det första kravet är att våra arbetssätt kan involvera och koppla samman fenomen på både lokal och global nivå, samt med både direkta och fördröjda kopplingar. Till exempel bör potentiella framtida förändringar i nederbörd beaktas i kommunala riskanalyser som ligger till grund för nyetablering av bostäder längs vatten-drag, eller vid dimensionering av nya system för dagvatten. &lt;br/&gt;&lt;br&gt; Det andra kravet är att våra arbetssätt kan involvera och tillgodose en mängd olika värden i samhället. Exempelvis vårt samhälles behov av en effektiv transport-infrastruktur samtidigt som det har behov av ökad personsäkerhet, skydd av miljön och demokrati.&lt;br/&gt;&lt;br&gt; Det tredje kravet är att våra arbetssätt kan inkludera en mängd olika händelser som kan ha en negativ påverkan på dessa värden. Till exempel jordskred, våldsamt upplopp, översvämning, algblomning, och så vidare. &lt;br/&gt;&lt;br&gt; Det fjärde kravet är att våra arbetssätt kan involvera och koppla samman en mängd faktorer och processer som bidrar till sårbarheten hos de värden som är viktiga i samhället i relation till påverkan från dessa negativa händelser. Exempelvis varför dricksvattensystemet är sårbart för terrorangrepp, södra Östersjön för algblomning och Malmö för starka stormar.&lt;br/&gt;&lt;br&gt; Det femte kravet är att våra arbetssätt kan involvera olika intressenter från olika samhällsfunktioner, administrativa nivåer och geografiska indelningar. Då utmaningar för hållbar utveckling sällan följer dessa mer eller mindre konstgjorda indelningar. &lt;br/&gt;&lt;br&gt; Det sjätte kravet är att våra arbetssätt kan koppla samman resultatet från flera riskanalyser utförda av olika grupper av intressenter. Exempelvis kan en länsstyrelse vilja skapa en översikt över riskbilden inom deras geografiska område och behöver då kunna väva samman resultaten från flera kommunala riskanalyser, detaljerade risk-analyser av fabriker och kärnkraftverk, etc. Något som de idag inte kan på grund av hur dessa analyser generellt sätt är genomförda och uppbyggda.&lt;br/&gt;&lt;br&gt; Med förståelse för dessa krav på riskanalyser för hållbar samhällsutveckling kan nya arbetssätt utvecklas. Arbetssätt som genom mer fokus på helheten kan ge samhället en bättre grund för att kunna styra utvecklingen mot ett mer hållbart samhälle. Mot ett samhälle som ger framtida generationer samma möjligheter till utveckling som idag och som är robust och hållbart mot tänkbara påfrestningar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/94b62e74-a37b-4086-af8a-d97593f925df</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="becker_kappa.pdf">https://portal.research.lu.se/files/3115492/1702334.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2066546</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Grasping_complexity_analysing_risk_for_sustainabl.pdf">https://portal.research.lu.se/files/3115494/1698168.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4315989</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>design</topic> <topic>sustainable development</topic> <topic>Development</topic> <topic>risk</topic> <topic>risk analysis</topic> <topic>sustainability science</topic> <topic>disaster</topic> <topic>value</topic> <topic>hazard</topic> <topic>vulnerability</topic> <topic>system</topic> <topic>capability</topic> <topic>human-environment systems</topic> <topic>systems approach</topic> <topic>design science.</topic> </subject> <subject authority="lup"> <topic>Other Civil Engineering</topic> <topic>Other Social Sciences</topic> <topic>Building Technologies</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">1698167</identifier> <part> <extent unit="pages"> <total>224</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-12-17T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>94b62e74-a37b-4086-af8a-d97593f925df</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:44+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-12-05T13:18:19Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:44+02:00</recordDateApproved> </recordInfo> </mods>

About 5-10% of all breast cancers are hereditary, with a monogenic inheritance pattern, but only 2-4% are explained by germline mutations in BRCA1 or BRCA2. BRCA1/BRCA2 mutation carriers have a 60-80% risk of developing breast cancer. Further, a large proportion of the breast cancers that are clustered in families are not associated with known disease-causing mutations. Those cases are likely to be explained by different combinations of low-penetrance genetic polymorphisms and exposure to other risk factors such as lifestyle, hormones, and high insulin-like growth factor 1 (IGF-1) levels. Such factors are also likely to influence the penetrance among high-risk women. Knowledge of which combinations of risk factors are important for the identification of women with high risk for early-onset breast cancer would allow more individualized risk assessments. For example, the absence of the common IGF1 19 CA-repeat allele in combination with oral contraceptive (OC) use has been associated with high IGF-1 levels. The aim of this thesis was to study genetic and non-genetic risk factors in women from high-risk breast cancer families. &lt;br/&gt;&lt;br&gt; In paper I, the variant allele (A2) of a SNP (rs743572) in the CYP17 gene was associated with short menstrual cycles and early OC use. The A2 allele was also more common among non-mutation carriers from BRCA1/2 mutation families.&lt;br/&gt;&lt;br&gt; In paper II, the absence of the common IGF1 19 CA-repeat allele was more common among BRCA1 mutation carriers than among non-carriers from BRCA1 families. This result confirms a previous finding of a smaller study.&lt;br/&gt;&lt;br&gt; In paper III, a three-way interaction between homozygous deletions of the GSTM1 and GSTT1 genes and OC use on IGF-1 levels was observed. Women who were lacking one, but not both, genes had the highest IGF-1 levels during OC use compared to OC users with either both genes deleted or both genes intact. &lt;br/&gt;&lt;br&gt; In paper IV, rare IGF1 diplotypes were associated with the absence of the common IGF1 19 CA-repeat allele, and they were more common among BRCA1 mutation carriers than other women from high-risk families. Rare diplotypes were also associated with breast cancer risk among all women and with an earlier age at first diagnosis of breast cancer among BRCA1 mutation carriers. &lt;br/&gt;&lt;br&gt; In conclusion, associations between genetic polymorphisms and other breast cancer risk factors need to be considered in future studies to understand their importance for breast cancer development and to improve current risk prediction models.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bröstcancer är den vanligaste cancerformen bland svenska kvinnor, fler än 7000 kvinnor insjuknar varje år. Mellan 5-10% av bröstcancerfallen tros bero på mutationer i arvsmassan som ärvts från föräldrarna. Om man har en ärftlig mutation i bröstcancergen 1 eller 2 (BRCA1 respektive BRCA2) löper man mellan 60-80% risk att drabbas av bröstcancer. Eftersom inte alla kvinnor som har en sådan mutation drabbas av bröstcancer och även kvinnor utan sådana mutationer drabbas av bröstcancer, tror man att samspelet mellan en rad andra faktorer är av betydelse för vem som insjuknar. Exempel på bidragande faktorer är normalt förekommande varianter i gener, så kallade polymorfier. Även hormonellt relaterade faktorer som hur gammal man är när man får sin första menstruation eller föder sitt första barn, liksom huruvida man använder p-piller eller ej, kan påverka risken. Olika kombinationer av riskfaktorer kan vara av betydelse för olika individer. Riskfaktorer kan också ha varierande betydelse för olika bröstcancertyper. Komplexiteten avseende flera faktorers samverkan bidrar till stora svårigheter att förutsäga vem som kommer att drabbas av bröstcancer och vid vilken ålder. Bland kvinnor med hög risk för tidig bröstcancer, baserat på förekomsten av cancer i släkthistorien, innebär detta att många blir föremål för omfattande uppföljning med t.ex. mammografi och läkarundersökning i syfte att tidigt hitta en eventuell cancer. Många kvinnor med hög risk baserat på släkthistorien väljer att operera bort sina ännu friska bröst, och/eller äggstockar, i förebyggande syfte. Med dagens riskskattnings-modeller, som ger ganska ”trubbiga” mått på risk, genomgår vissa kvinnor sådan uppföljning eller förebyggande kirurgi i onödan. Samtidigt finns det en stor andel kvinnor som baserat på släkthistorien inte har så hög risk, men som ändå drabbas av bröstcancer. Dessa kvinnor hade kanske med mer individanpassade riskskattningsmodeller kunnat undvika bröstcancer genom förebyggande kirurgi. &lt;br/&gt;&lt;br&gt; Studierna som ingår i avhandlingen gjordes i syfte att bättre förstå samspelet mellan olika riskfaktorer för bröstcancer. Sådan förståelse skulle kunna bidra till utvecklandet av mer specifika riskskattningar. Studiepopulationen består av kvinnor från familjer med hög risk för bröstcancer. En del av kvinnorna bär på en mutation i BRCA1- eller BRCA2-genen. Vi analyserade normalvarianter i olika gener som tidigare kopplats till bröstcancerrisk eller till någon riskfaktor. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Cytokrom P450c17α är ett enzym vars gen (CYP17) bland annat innehåller en normalvariant vilken kan påverka nedbrytandet av östrogen och därigenom risken för bröstcancer. I första arbetet (paper I) undersöktes genvarianten i relation till reproduktiva faktorer. Vidare studerades hur vanlig genvarianten var bland kvinnor med och utan BRCA1- och BRCA2-mutationer. Bland de 254 kvinnorna för vilka CYP17-polymorfin kunde analyseras, var det vanligare med korta menstruationscykler och användning av p-piller från ung ålder om man hade den genetiska varianten jämfört med om man hade den vanliga. Både korta menstruationscykler och användning av p-piller i ung ålder är riskfaktorer för bröstcancer. Vidare var den genetiska varianten vanligare bland kvinnor som inte var BRCA1- eller BRCA2-mutationsbärare jämfört med de med en mutation. Framtida studier av CYP17 varianten i relation till bröstcancer bör ta hänsyn till dessa faktorer för att bättre förstå hur varianten är kopplad till bröstcancerrisk. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I nästa arbete (paper II) studerades en normalvariant i genen som kodar för tillväxtfaktorn insulin-like growth factor 1 (IGF1). Denna normalvariant har tidigare visats vara kopplad till ökad risk för bröstcancer, särskilt bland kvinnor som använder p-piller. Vi fann en ökad förekomst av IGF1-genvarianten bland kvinnor som också bär på en BRCA1-mutation. Om fyndet bekräftas av ytterligare studier kan information om individers IGF1-genotyp vara värdefull för att förbättra genetisk rådgivning avseende t.ex. p-pillerbruk. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Glutathione S-transferas-enzymerna GSTM1 och GSTT1 är involverade i nerbrytningen av östrogener. I det tredje delarbetet (paper III) studerades genvarianter, som leder till avsaknad av det ena eller båda enzymen, i relation till cirkulerande IGF-1 i blodet. Eftersom nivån av IGF-1 i blodet påverkas av hormonerna som finns i p-piller, analyserades p piller-användare och icke-användare separat. De genetiska varianternas koppling till IGF-1 påverkades av huruvida man var p-pilleranvändare eller ej. Bland kvinnor som inte använde p-piller sågs relativt lägre nivåer av IGF-1 hos de som saknade GSTM1 eller GSTT1 men högre hos de som saknade eller hade båda två. Bland p-pilleranvändarna var det tvärtom de som bara saknade ett av dessa enzym som hade de högsta nivåerna av IGF-1. Höga IGF-1 nivåer har kopplats till ökad risk för tidig bröstcancer. Det är möjligt att enbart kvinnor med ett av GSTM1 eller GSTT1 löper ökad risk för bröstcancer vid p-pillerbruk då de i vår studie hade relativt högre IGF-1 nivåer. Om fyndet bekräftas skulle dessa kvinnor kunna rekommenderas att använda annan preventivmetod än p-piller. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I det sista delarbetet (paper IV) studerades cirkulerande nivåer av IGF-1, BRCA1- och BRCA2-mutationer, IGF1-genvarianten som studerades i arbete II, samt ålder vid bröstcancerdiagnos i relation till den genetiska variationen i hela IGF1-genen. Variationen i hela genen definierades med hjälp av ett antal markörer för variationen i mindre delar av genen. Olika kombinationer av markörerna kunde sedan användas för att beskriva variationen i IGF1-genen uppdelat på tre stora områden. Variationen inte var kopplad till nivån av IGF-1 i blodet men ovanliga varianter var vanligare bland BRCA1-mutationsbärare. De ovanliga varianterna var också vanligare bland kvinnor med den enskilda IGF1-varianten som studerades i arbete II. Slutligen var de ovanliga varianterna kopplade till högre risk för bröstcancer och tidigare insjuknande bland kvinnor med BRCA1-mutation. Om fyndet bekräftas är det möjligt att kvinnor med både BRCA1 mutation och ovanliga IGF1 varianter kan komma att erbjudas tidigarelagd undersökning av brösten eller förebyggande kirurgi.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/86e56e77-d133-43a5-98db-b5023e585015</url> </location> </relatedItem> <originInfo> <publisher>Department of Oncology, Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>familial breast cancer</topic> <topic>premenopausal women</topic> <topic>htSNP</topic> <topic>GSTP1</topic> <topic>polymorphism</topic> <topic>BRCA1</topic> <topic>BRCA2</topic> <topic>IGF-1</topic> <topic>oral contraceptives</topic> <topic>CYP17</topic> <topic>GSTT1</topic> <topic>GSTM1</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-08-2</identifier> <identifier type="oldLupId">1690090</identifier> <part> <detail type="volume"> <number>2010:92</number> </detail> <extent unit="pages"> <total>168</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-11-09T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>86e56e77-d133-43a5-98db-b5023e585015</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:49+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:49+02:00</recordDateApproved> </recordInfo> </mods>

The overall aim of this thesis was to investigate if hairdressers have an ongoing exposure to selected carcinogenic aromatic amines. &lt;br/&gt;&lt;br&gt; We recruited 295 hairdressers, 32 consumers of hair dyes and 60 controls. All participants were non-smoking females, 18-55 years of age. Exposure over the past 4 months was determined for eight aromatic amines measured as haemoglobin (Hb) adducts. Hb adduct concentrations for hairdressers and consumers were not significantly higher than those of the controls for any of the eight aromatic amines. However, within the hairdresser group, ortho (o) and meta (m)-toluidine adduct concentrations tended to increase with the number of performed treatments with light-colour oxidative hair dyes. Furthermore, Hb adduct concentrations of o-toluidine increased significantly with the number of performed treatments of hair waving and m-toluidine adducts with the number of performed treatments with other oxidative hair dye. &lt;br/&gt;&lt;br&gt; Professional hair products, mainly oxidative hair dyes, were collected from hairdressing salons and analysed for o-toluidine content. o-Toluidine was found in most of the analysed oxidative hair dyes but with a wide range in concentrations, even for the same colours. For semi-permanent (non-oxidative) hair dyes, oxidizing agents, hair waving products, and bleaching products, the content of o-toluidine was low or below limit of quantitation.&lt;br/&gt;&lt;br&gt; To explore the effect of exposure to o- and m-toluidine among hairdressers, we determined telomere length and methylation of genes related to bladder or lung cancer. Hairdressers had a modest shortening of telomere length compared to non-hairdressers. No overall associations between telomere length and any of the Hb adducts were found, and no clear patterns between exposure as a hairdresser and hypermethylation of the selected genes. &lt;br/&gt;&lt;br&gt; In conclusion hairdressers seem to have an ongoing occupational exposure to o- and m-toluidine as indicated by the associations with performed treatments with light-colour oxidative hair dye, other oxidative hair dye and hair waving. This is further supported by our finding of o-toluidine in most of the analysed oxidative hair dyes. However, no clear patterns were found between exposure as a hairdressers and hypermethylation of genes associated with bladder cancer and lung cancer. We observed a modest shortening of telomere length among the hairdressers, but the causality of the observation is uncertain since no overall exposure-response association was observed.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ab8867ee-918a-495a-b20a-eefd861dbf70</url> </location> </relatedItem> <originInfo> <publisher>Division of Occupational and Environmental Medicine</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-150-7</identifier> <identifier type="oldLupId">5423853</identifier> <part> <detail type="volume"> <number>2015:71</number> </detail> <extent unit="pages"> <total>65</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-06-11T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>ab8867ee-918a-495a-b20a-eefd861dbf70</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:51+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:51+02:00</recordDateApproved> </recordInfo> </mods>

It uses a model-based approach to find the critical process parameters, analyze the control space and suggest a design space that can be registered with the regulatory agencies. The methodology starts with a method for model calibration and validation. The model is then used to find an optimal operating point for an ideal scenario without process disturbances. Process disturbances are then added and the operating point is moved to a more robust one so that the process has a high overall performance. Sample-based uncertainty analysis can be used to estimate the probability of batch failure at a point or to determine robust UV cut points such that no batches will fail due to process disturbances. These same simulations can also be used to determine the critical process parameters.&lt;br/&gt;&lt;br&gt; The methodology is then extended to define a design space. This is done by defining the design space by optimal operating points for different scenarios. This means that the process can be optimized for future changes in cost and process parameters. This gives a limited set of operating points to be validated and registered with the regulatory agencies. The method can also be used to determine the benefits of reducing the process disturbances at a particular operating point. This provides decision support when determining the quality of process equipment that is required, as higher quality equipment will require a larger investment.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/db70a31e-573b-40fe-8c42-f4d9e4eb17a0</url> </location> </relatedItem> <originInfo> <publisher>Department of Chemical Engineering, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>sensitivity analysis</topic> <topic>optimization</topic> <topic>modeling</topic> <topic>preparative chromatography</topic> <topic>Design space</topic> <topic>Control Space</topic> <topic>uncertainty analysis</topic> </subject> <subject authority="lup"> <topic>Chemical Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-628-7732-3</identifier> <identifier type="oldLupId">1359911</identifier> <part> <extent unit="pages"> <total>63</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-08T13:30:00+02:00</dateOther> <recordInfo> <recordIdentifier>db70a31e-573b-40fe-8c42-f4d9e4eb17a0</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:52+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:52+02:00</recordDateApproved> </recordInfo> </mods>

Two fundamental processes contribute to the development of type 2 diabetes: insulin resistance in target organs and insufficient insulin secretion from the pancreatic beta-cells. The aim of this thesis was to explore the role of DNA methylation and common genetic variation on glucose metabolism and the pathogenesis of type 2 diabetes.&lt;br/&gt;&lt;br&gt; Reduced oxidative capacity of the mitochondria in skeletal muscle has been suggested to play a role in insulin resistance and type 2 diabetes. In studies I and II, we investigated the regulation of COX7A1 and ATP5O, which encode two subunits of the mitochondrial respiratory chain. We found that genetic variation and age were associated with skeletal muscle mRNA expression in both studies. mRNA levels were also positively correlated with the expression of the transcriptional co-activator PPARGC1A and insulin-stimulated glucose uptake, i.e., elderly individuals had reduced mRNA expression levels and reduced in vivo glucose uptake. Additionally, DNA methylation of the COX7A1 promoter was increased in elderly individuals concordant with the decrease in COX7A1 mRNA expression, suggesting a role for genetic, epigenetic and non-genetic factors in gene regulation.&lt;br/&gt;&lt;br&gt; In study III, we investigated a common genetic variant in MTNR1B that has previously been found to be associated with increased risk of type 2 diabetes, increased fasting plasma glucose and impaired insulin secretion in populations of European ancestry. We aimed to replicate these findings in a type 2 diabetes case-control cohort of Han Chinese ancestry. We confirmed the association between rs10830963 and both the risk of type 2 diabetes and increased fasting plasma glucose levels, suggesting a relatively ancient origin for this variant.&lt;br/&gt;&lt;br&gt; In study IV, common genetic variants that introduce or remove potential DNA methylation sites were selected based on their association with the risk of type 2 diabetes and changes in gene expression in blood. These genetic variants were analysed together with the level of DNA methylation and gene expression in human skeletal muscle, adipose tissue, blood and pancreatic islets. We found that 18 of the 19 sites that we analysed were associated with a difference in DNA methylation related to genotype, and for 11 of these sites this finding was consistent in all four tissues. Additionally, our data suggested a tissue-specific pattern of DNA methylation. Our results confirm an interaction between genetic and epigenetic mechanisms, which introduces a new level of complexity to our knowledge of gene regulation in type 2 diabetes.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Diabetes är en grupp sjukdomar som alla kännetecknas av en förhöjd nivå av sockerarten glukos i blodet. Antalet individer som drabbas av diabetes ökar hela tiden, en utveckling som ses över hela världen. Bara i Sverige har drygt 5% av befolkningen diagnosen diabetes, motsvarande 484.400 personer i åldern 20-79 år.&lt;br/&gt;&lt;br&gt; Typ 2 diabetes är den vanligaste formen av diabetes, och kallades tidigare också åldersdiabetes. Denna form av diabetes är förknippad med övervikt och för lite motion. För att kroppen ska fungera optimalt måste halten av glukos i blodet hela tiden hållas på en jämn nivå, oavsett om man precis ätit en stor måltid eller om man sover. Stigande glukosnivåer i blodet regleras med hjälp av hormonet insulin, som får kroppens celler, framför allt i muskel och lever, att ta upp och lagra glukos. Insulin tillverkas och utsöndras från betaceller i bukspottskörteln.&lt;br/&gt;&lt;br&gt; Orsaken till typ 2 diabetes är ännu inte helt känd, men man vet att både miljöfaktorer och flera olika ärftliga faktorer spelar roll. Sjukdomen föregås ofta av en längre tid med insulin-resistens, ett tillstånd där kroppens celler inte längre svarar normalt på insulinets verkan, vilket försämrar upptaget av glukos från blodet. Till en början kan kroppen kompensera genom att öka utsöndringen av insulin, men när betacellerna i bukspottskörteln inte längre klarar av att upprätthålla detta stiger glukoshalterna och resulterar i typ 2 diabetes. Kroniskt höga halter av glukos i blodet kan ge upphov till en rad komplikationer, tex hjärt- och kärlsjukdomar som också är en av de största dödorsakerna i typ 2 diabetes.&lt;br/&gt;&lt;br&gt; Glukos som tas upp av kroppens celler kan lagras för senare bruk eller användas för att producera energi. Mitokondrien är den enhet i kroppens alla celler som står för produktionen av energi, i form av en molekyl som kallas ATP. Mitokondrien är uppbyggd av flera mindre enheter, och delar av dessa har visat sig vara mindre uttryckta i muskel hos patienter med typ 2 diabetes än i friska individer. Detta kan leda till att energiproduktion och omsättning av glukos i cellen inte fungerar optimalt, och därmed försämras också upptag av glukos från blodet till cellerna. &lt;br/&gt;&lt;br&gt; Vi har studerat två delar i mitokondriens mindre enheter, COX7A1 och ATP5O, för att ta reda på vad som reglerar deras uttryck och på så sätt kunna förstå varför nivåerna av dem är sänkta i muskelceller från typ 2 diabetiker. Vi fann att både COX7A1 och ATP5O påverkas negativt av ökad ålder och av ärftliga faktorer, och vi upptäckte också att en minskning av dem bidrog till sämre glukosupptag från blodet. COX7A1 visade sig också vara negativt påverkad av epigenetiska faktorer, i form av ökad DNA-metylering.&lt;br/&gt;&lt;br&gt; Epigenetik är ett dynamiskt fenomen som kan kontrollera när, var och hur ett arvsanlag ska komma till uttryck. Epigenetiska förändringar inträffar under livets gång och skiljer sig åt mellan olika celler och olika organ. Detta är i stor kontrast till genetiken, som omfattar vårt arvsanlag ordnat i en lång kedja av DNA som är konstant över tid och i alla kroppens celler. Ordningen på beståndsdelarna i DNA-kedjan utgör den genetiska informationen, vårt arv. Epigenetiken påverkar inte arvsmassan direkt, men kan påverka hur arvsmassan tolkas och kommer till uttryck i kroppen, och fungerar som cellens minne.&lt;br/&gt;&lt;br&gt; DNA-metylering är ett exempel på epigenetisk reglering, där en metylgrupp (-CH3) binder till DNA-kedjan och påverkar hur arvsanlaget kommer att tolkas. Detta är en reversibel process, dvs metylgrupperna kan tas bort igen, och beroende på i vilka celler och organ, samt när DNA-metyleringen sker, så kommer vårt arvsanlag att uttryckas på olika sätt.&lt;br/&gt;&lt;br&gt; Vanligt förekommande genetisk variation kan användas för att identifiera regioner i vår arvsmassa som ökar risken för att drabbas av sjukdomar, som tex typ 2 diabetes. Vi har studerat genetisk variation i en region av arvsmassan som innehåller genen för MTNR1B. Uttryck av denna gen ger produktion av en enhet där melatonin kan binda in, ett hormon som påverkas av ljuset och hjälper kroppen att reglera dygnsrytmen. Genetisk variation i MTNR1B har tidigare visat sig ha ett samband med risk att drabbas av typ 2 diabetes. Arvsanlaget skiljer sig åt mellan olika individer och det är därför vi alla är olika och har olika risk för att drabbas av sjukdomar. Skillnaderna i arvsanlag skiljer sig dessutom åt mellan personer med olika etniskt och geografiskt ursprung. Vårt syfte var att ta reda på om den genetiska variationen i MTNR1B som ökar risken för typ 2 diabetes i européer, också har samma effekt hos personer från Shanghai i Kina. Resultaten visade att samma genetiska variation var förknippad med ökad risk för typ 2 diabetes och med högre blodsockernivåer också i de studerade individerna från Kina. Effekten var av samma storlek som visats i européer i de tidigare studierna, men riskvarianten är vanligare i individerna med kinesiskt ursprung och har därför påverkan på en större andel av befolkningen.&lt;br/&gt;&lt;br&gt; Slutligen ville vi kombinera genetisk variation med DNA metylering för att få djupare förståelse av hur regleringen av vårt arvsanlag går till. Vi valde genetiska varianter som tidigare visat sig ha en koppling till typ 2 diabetes och som också påverkar hur arvsanlagen i närheten uttrycks i blod. Dessutom inkluderades bara genetiska varianter som kan påverka DNA-metylering, dvs som antingen ger upphov till eller tar bort en sekvens i DNAt där en metylgrupp kan binda in. Vi fann att majoriteten av de varianterna vi undersökt förändrade graden av DNA-metylering i det specifika området, och att detta också i vissa fall påverkade uttrycket av arvsanlaget.&lt;br/&gt;&lt;br&gt; Identifiering av nya gener och nya mekanismer för hur dessa kan påverka kroppens funktion leder till ökad förståelse för sjukdomens utveckling. I slutändan kan detta användas för förbättrad behandling eller förebyggande av typ 2 diabetes.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3c051039-4be6-4e87-82ad-b43975ff15f6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_Tina_Ronn.pdf">https://portal.research.lu.se/files/3117187/1590087.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1012229</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Tina Rönn, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>gene expression</topic> <topic>oxidative phosphorylation</topic> <topic>GWAS</topic> <topic>SNP</topic> <topic>DNA methylation</topic> <topic>epigenetics</topic> <topic>type 2 diabetes</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-73-3</identifier> <identifier type="oldLupId">1590078</identifier> <part> <detail type="volume"> <number>2010:58</number> </detail> <extent unit="pages"> <total>121</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-27T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>3c051039-4be6-4e87-82ad-b43975ff15f6</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:53+02:00</recordDateApproved> </recordInfo> </mods>

In the intact brain, these NSCs give rise to new dentate granule cells and olfactory bulb neurons, respectively. Following a brain damage such as stroke and an epileptic seizure, the generation of new neurons (neurogenesis) in the hippocampus and the SVZ in adult rats, mice and probably humans is increased. The molecular mechanisms regulating the different steps of insult-induced neurogenesis (cell proliferation, survival, migration, and differentiation) are poorly understood. To learn more about the molecular mechanisms regulating neurogenesis we examined which factors in the epileptic and stroke generated environment that affects the newly formed neurons. &lt;br/&gt;&lt;br&gt; In this thesis we explored the role of a prostaglandin and a cytokine in the hippocampus and subventricular zone, both during physiological conditions and after an insult. In the first paper we induced status epilepticus (SE) in rats by electrical stimulation in the hippocampus. We then compared the two different seizure grades, partial status epilepticus (pSE) and generalized status epilepticus (gSE), in order to identify factors in the microenvironment which are differentially regulated by SE severity and may underlie differences in neurogenesis. We particularly addressed the question whether SE severity differentially affects the expression of prostaglandin E2 (PGE2), cyclooxygenase (COX-2), the enzyme catalyzing the first committed step in PGE2 synthesis, and the brain-derived neurotrophic factor (BDNF). In conclusion, the results from paper I showed clear differences between pSE and gSE rats in hippocampal PGE2 and BDNF levels 7 days after SE. We found no evidence that the high levels of PGE2 and BDNF, in rats exhibiting pSE, during the first days after SE are of major importance for the survival of new neurons during the first days after formation.&lt;br/&gt;&lt;br&gt; In the second study, we developed a new SE model for mice based on continuous electrical stimulation in the hippocampus, as done previously in rats. We then investigated whether the cytokine, tumor necrosis factor alpha (TNF-α), could influence neurogenesis. &lt;br/&gt;&lt;br&gt; TNF-α is a well-known proinflammatory factor and we speculated that the detrimental action of inflammation on insult-induced neurogenesis might be caused by TNF-α. It had also been shown that NSCs themselves express TNF-α, which raised the possibility of an autocrine action involved in neurogenesis. We used transgenic mice with various genetic manipulations of TNF-α signaling to determine the influences on neurogenesis under physiological conditions and following a brain insult. Taken together, the results from paper II demonstrate the involvement of TNF-R1 and TNF-R2 signaling in the regulation of adult hippocampal neurogenesis, and that signaling through the two different receptors have differential actions on neurogenesis. Our data indicate that TNF-α can modulate the formation of new neurons both under physiological and pathological conditions by acting on these two receptors with differential effects on proliferation and survival, with TNF-R1 as the key mediator of TNF-α signaling.&lt;br/&gt;&lt;br&gt; In the final study we examined whether signaling through TNF-R1 could influence progenitor proliferation in another neurogenic area during physiological conditions and following a pathological condition such as stroke and SE. We used the same transgenic mice to study TNF-α and its effects on the formation of new neurons in the SVZ. We found that mice lacking TNF-R1 function responded to stroke with enhanced SVZ cell proliferation and thereby that TNF-R1 signaling mediates a suppressant effect on the proliferation of progenitor cells. Following stroke TNF-R1 acts as a negative regulator on the progenitor proliferation. In contrast, deletion of TNF-R1 did not influence basal cell proliferation in SVZ. Further, loss of TNF-R1 function had differential effects on SVZ cell proliferation following the two pathological conditions SE and stroke and we did not find any differences in cell proliferation after SE. Although both insults gave rise to increased cell proliferation in the SVZ, the dampening action of TNF-R1 on proliferation was revealed only after stroke. &lt;br/&gt;&lt;br&gt; Taken together, the results from paper II and III suggest that suppression of TNF-R1 signaling might be a strategy to promote the proliferative response in the SGZ after SE and in the SVZ after stroke, to stimulate neurogenesis in the adult brain. However, it will be important to establish how such an approach will affect other steps of neurogenesis and the functional outcome after both SE and stroke.&lt;br/&gt;&lt;br&gt; There could be a positive therapeutic potential of neurogenesis from endogenous stem cells after brain insults. However, we need to know much more about the regulation of neurogenesis in order to make this response more effective. The current thesis work aims at elucidating some of the mechanisms of neuronal self-repair, which could have implications for the development of stem cell-based approaches for the treatment of brain disorders.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/775c4b81-03f2-4d1b-b54e-f4082c2558ef</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="ThesisRobertEIosif.pdf">https://portal.research.lu.se/files/3117527/1144927.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">14499021</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Other Clinical Medicine</topic> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-20-0</identifier> <identifier type="oldLupId">1144923</identifier> <part> <detail type="volume"> <number>2008:67</number> </detail> <extent unit="pages"> <total>116</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-17T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>775c4b81-03f2-4d1b-b54e-f4082c2558ef</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:01:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:01:58+02:00</recordDateApproved> </recordInfo> </mods>

Recent studies proposed a role for cancer initiating cells (CICs), a small subset of replication-competent cells, in colon carcinogenesis. Although the role of inflammatory lipid-mediators in CRC progression is well known, their role in the promotion of cancer-initiating cells remains to be elucidated. For this thesis, we investigated the role of eicosanoids – leukotriene D4 (LTD4) or prostaglandin E2 (PGE2) – on CIC properties and changes occurring in the tumor environment that could possibly support CIC-induced tumor growth. To this end, we identified the CICs on the basis of ALDH expression and evaluated their in vitro characteristics like colony formation, radio or chemoresistance and in vivo tumorigenic properties in the presence of LTD4 or PGE2. We showed that LTD4 and PGE2 enriched the ALDH+ cell population&lt;br/&gt;&lt;br&gt; and augmented the colonies formation and tumor progression in xenograft mice model. The ALDH+ cells were also resistant to 5-fluorouracil and radiation that is additionally augmented by both the lipid-mediators. Moreover&lt;br/&gt;&lt;br&gt; the impact of lipid inflammatory mediators on the stemness properties of CICs was evident by increased expression of genes that confer survival and self-renewal ability to CICs. In immunodeficient mice, LTD4 or PGE2&lt;br/&gt;&lt;br&gt; treatment amplified CIC-induced tumor growth. Furthermore, LTD4 and PGE2 increased cell proliferation activated β-catenin signaling and up-regulated COX-2. Additionally, LTD4 or PGE2 drive massive inflammatory responses identified as CD45+ enrichment, particularly of macrophages within tumors. The ability of ALDH+ cells to form tumors in immunodeficient mice could not be challenged by radiation therapy.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In a separate series of experiments, we investigated the contribution of CICs in the development of sensitivity against montelukast, a CysLT1R antagonist. In this context we report that sensitivity of tumors against&lt;br/&gt;&lt;br&gt; montelukast could depend on the variation in CICs content, activation of prosurvival factors such as BCL-2 and β-catenin signaling. Collectively, our data showed that LTD4 and PGE2 exacerbate CIC characteristics and promote&lt;br/&gt;&lt;br&gt; tumor growth by allowing modifications in the tumor environment. New therapeutic strategies could aim to resolve not only cancer associated inflammation, but also to target CICs in order to achieve better remission and cure advanced colon cancer stages.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0508131a-f493-4934-b5ea-5b2460767f5b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kishan_Bellamkonda_Thesis_.pdf">https://portal.research.lu.se/files/3121654/4934698.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">33204180</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-071-5</identifier> <identifier type="oldLupId">4927666</identifier> <part> <detail type="volume"> <number>2015:18</number> </detail> <extent unit="pages"> <total>60</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-01-16T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>0508131a-f493-4934-b5ea-5b2460767f5b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:02:10+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:02:10+02:00</recordDateApproved> </recordInfo> </mods>

They are generated in the thymus from bone marrow derived progenitors, where they undergo commitment to the T cell lineage and differentiate and mature into naïve CD4+ and CD8+ T cells. Naïve CD4+ and CD8+ T cells activation takes place in lymphoid organs after recognition of cognate antigen in the context of major histocompatibility complex (MHC) molecules on antigen presenting cells (APCs). The effector functions of CD8+ T cells includes the MHC-I dependent recognition and lysis of target cells (e.g. virally infected cells) through the release of degranulating cytotoxic mediators but CD8+ T cells can also acquire suppressive functions (CD8+ regulatory T cells (Tregs). Activation of naïve CD4+ T cells leads to the generation of T helper cell subsets (Th, e.g. T helper (Th1), Th2, Th17 and CD4+ Tregs) and the type of Th cell that is generated during an immune response is largely dependent on the cytokine signals these cells receive during their initial activation in the lymph node.. The main function of CD4+ Th cells is to produce cytokines that that impact on the differentiation, recruitment and functionality of other immune and stromal cells, and as such these cells play a central role in shaping immune responses. Following an immune response some antigen-specific T cells remain as memory T cells. Memory T cells are long-lived and serve to protect us against re-infection with the same pathogen. The overall aim of this thesis was to study mechanisms regulating differentiation and functionality of intestinal CD4+ and CD8+ T cells.&lt;br/&gt;&lt;br&gt; Memory CD4+ T cells is found in the circulation as well as in tissues. In addition to responding to re-infections in an antigen dependent manner these circulating memory CD4+ T cells can produce interferon (IFN)-γ in response to cytokines in the absence of T cell receptor (TCR) stimulation, suggesting that they may participate in immune responses in an innate-like manner. We could show that IL-15 or tumor necrosis factor (TNF)-like cytokine 1A(TL1a) induced production of IL-5, IL-6, IL-13, IL-22, granulocyte–macrophage colony-stimulating factor (GM-CSF), IFN-γ and TNF-α in a subset of memory CD4+ T cells co-expressing death receptor 3 (DR3) and IL-18Rα in presence of IL-12 and IL-18. TL1a synergized with IL-15 to further enhance the levels of all cytokines measured and the cytokine-induced cytokine production was severely diminished in the absence of IL-18. The intestine is a large reservoir of memory CD4+ T cells and we could show that a large proportion of these cells co-expressed IL-18Rα and DR3 in both humans and mice and these cells produced cytokines in response to cytokine stimulation. These results suggest that both human and murine memory IL-18Rα+DR3+ CD4+ T cells may contribute to antigen-independent innate-like responses in the intestine.&lt;br/&gt;&lt;br&gt; We also found that CD4+ T cells expressing IL-18Rα and DR3 were present in the inflamed small intestine in patients with Crohn’s disease (CD), a chronic inflammatory disease that can affect all areas of the gastrointestinal tract, where theu co-localized with IL-18-expressing cells in intestinal lymphoid aggregates. This suggests that cytokine-activated CD4+ T cells might contribute to the high levels of proinflammatory cytokines observed in these patients. Bioactive IL-18 mRNA transcripts are increased in mucosal samples obtained from CD compared to controls. The role of IL-18 in intestinal inflammation has been thoroughly studied in various animal models of IBD and while most of these mice are protected from severe intestinal inflammation in absence of IL-18 there are also studies suggesting a protective role for IL-18. Although IL-18 is a pleotropic cytokine all of these studies was carried out by systemically blocking IL-18 signalling and did not take into account what cells that were affected. In the CD45RBhigh CD4+ T cell transfer model of IBD we could observe that all CD4+ T cells recovered from mesenteric lymph node and colon lamina propria (LP) expressed IL-18Rα in the setting of colitis. To identify a potential role of IL-18 signalling in CD4+ T cells ability to induce colitis in this model we transferred il-18r-/- CD45RBhighCD4+ T cells into rag-1-/- mice. The number of IFN-γ producing CD4+ T cells recovered from the colitic colon LP were significantly reduced compared to their wild type counterparts and il-18r-/- CD4+ T cells in the setting of colitis failed to produce cytokines in response to cytokine stimulation. Despite these findings il-18r-/- CD4+ T cells were equally proficient at inducing colitis as those CD4+ T cells from wild type mice. These results suggesting that IL-18 signaling in CD4+ T cells is not critical for their ability to drive disease pathology in the CD45RBhigh transfer model of colitis.&lt;br/&gt;&lt;br&gt; The intestine is daily exposed to large amounts of antigens and is the major entry site for intracellular bacteria whose control requires the induction of protective CD8+ T cell responses. In the intestinal fatty acid-binding protein promoter truncated ovalbumin (iFABP-tOVA) mouse in which a surrogate antigen is expressed in the small intestinal epithelium we assessed mechanisms regulating mucosal CD8+ T cell priming and differentiation in the steady state and inflammatory setting. CD8+ T cells were found to differentiate into two distinct subsets, CD107a/b+ cytotoxic T cells (CTLs) and FoxP3+CD8+ T cells. FoxP3+CD8+ T cells but not CTLs required chemokine receptor 9 (CCR9) for effective homing to and expansion within the small intestinal mucosa. Further, we found that IRF8, but not IRF4, expression by intestinal dendritic cells (DCs) was critical for the development of the FoxP3+ subset in steady state but not the inflammatory setting. Collectively these findings broaden our understanding of the mechanisms regulating CD8+ T cell responses in the intestinal mucosa and have potential implications for mucosa vaccine design.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ecfe2482-964e-4280-abf7-d2ce80a2af28</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Petra_Holmkvist.pdf">https://portal.research.lu.se/files/3121737/4698658.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8299732</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Immunology</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>T cells</topic> <topic>memory</topic> <topic>intestine</topic> <topic>cytokines</topic> <topic>differentiation</topic> <topic>IL-18</topic> <topic>inflammation</topic> <topic>antigen presentation</topic> </subject> <subject authority="lup"> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> <topic>Basic Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-047-0</identifier> <identifier type="oldLupId">4698563</identifier> <part> <detail type="volume"> <number>2014:118</number> </detail> <extent unit="pages"> <total>76</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-07T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>ecfe2482-964e-4280-abf7-d2ce80a2af28</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:02:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:02:11+02:00</recordDateApproved> </recordInfo> </mods>

It has been shown that the vascular endothelin receptor expression is increased in stroke and organ culture. Furthermore, studies have demonstrated the intracellular signalling pathways, leading to the enhanced expression of vascular endothelin receptors. We have revealed that both calcium calmodulin dependent protein kinase and mitogen activated protein kianses play an important role. The signal transduction processes lead to powerful and prolonged effects of the initial activation. The synergistic nature of these processes, involve several gene groups. Our hypothesis is that inhibition of CAMK signal transduction would have effects on genes that are involved in cerebral ischemia and cerebrovascular receptor upregulation.&lt;br/&gt;&lt;br&gt; The results of these studies show that the effect of CAMK or ERK1/2 inhibitor was stronger and more effective compared to that of other MAPK kinases. On the other hand the ability of CAMK to attenuate the contractions induced not only by endothelin receptors but also potassium depolarization revealed the unique role of CAMK in contraction of cerebral arteries. Investigation of the CAMK intracellular pathways shows the dependence of the intra-cellular calcium channel IP3R and CAMK on endothelin receptor expression. &lt;br/&gt;&lt;br&gt; Further in vivo studies using the SAH model in rat showed that a CAMK inhibitor attenuated contractions induced by ET-1. It suggests an important role of the CAMK in late vasospasm after SAH. &lt;br/&gt;&lt;br&gt; This thesis provides new perspectives on the pathophysiology of cerebral ischemia, and provides a possible explanation to the beneficial effects of treatment with CAMK inhibitors to limit the sequels of cerebral ischemia.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Hjärnan är ett organ som utgör 2 % av kroppsvikten men som mottar ca 20 % av hjärtats minut volym och har en mycket hög energi konsumtion. I samband med en blodpropp i något av hjärnas blodkärl eller att ett av hjärnans kärl brister får man en stroke eller cerebral ischemi. Man har under många decennier inriktad sig på den akuta behandlingen på att finna ett sätt att reducera skadorna genom s k neuroprotektion; man har då fokuserat på överlevnad av hjärnans celler och lagt relativt lite fokus på den hjärnans blodkärl. Vi har studerat hjärnans blodkärl och kartlagt dess receptorer. Nu har vi funnit att i samband med en stroke sker en receptor uppreglering av kontraktila receptorer (tillkomst av fler receptorer) i stora och små blodkärl associerade med hjärnskadan. Detta sker genom tidig aktivering av mitogen aktiverade protein kinases (MAPK) typ MEK/ERK1/2 vägen. Vårt arbete syftar till att kartlägga dessa proteiner i detalj och i föreliggande avhandling undersöktes CAMK systemet som vi nu visat kunna samarbeta med MEK/ERK. &lt;br/&gt;&lt;br&gt; Arbetet är baserat på experiment utförda på isolerade blodkärl från hjärnan där dessa kärl inkuberats i ”organ kultur” som är en modell att få fram samma typ av receptor förändring som vi sett i samband med experimentell stroke. I delarbete I studerades hur olika MAPK blockare kan hämma endothelin receptor uppreglering. Ett antal antagonister har studerats i detalj för att karakterisera när och i vilken dos de bäst kan hämma de undersökta protein kinaserna.. Vi fann att MEK/ERK1/2 hämmare har större betydelse jämfört med andra kinaser.&lt;br/&gt;&lt;br&gt; Arbete II jämförde CAMK och ERK signalvägarna, samt undersökte tidens betydelse för inhibitor påverkan på endothelin receptor uttrycket. Detta gav betydelsefulla resultat som visar att CAMK eller ERK inhibitorer har mer påverkan efter att signalvägen MEK/ERK har påbörjat sin aktivitet (dvs 6 timmar efter inkubation). Resultaten har stor betydelse i kliniska sammanhang då vi avser att försöka finna ett medel med klinisk effekt. För att i större detalj undersöka de cellulära mekanismer som deltar i denna process utfördes delarbete III med frågeställningen hur påverkats intracellulära signalvägar för endothelin receptor uttrycket. Detta arbete var fokuserat på hur calcium calmodulin-beroende protein kinase (CAMK), calcium kanaler och transkriptionsfaktorer inverkar på denna process. Vi har satt upp och utfört flera nya tekniker; bland annat studier av intracellulärt calcium i samband med receptor aktivering och undersökt effekterna och inverkan av olika typer av jonkanaler på endotel receptor uttrycket. Arbetet visar att CAMK och inositol trifosfat receptorn samt två transkriptionsfaktorer har en betydelsefull roll i processen kring endothelin receptor uppreglering. &lt;br/&gt;&lt;br&gt; CAMK visade en signifikant effekt på endothelin receptor upreglering hos cerebrala blodkärl vid organ kultur vilket resulterade i att vi utförde en in vivo studie av CAMK på experimentell SAH. I denna modell för subaraknoidal blödning undersökte vi om CAMK inhibition kan påverka receptor uppreglering av endothelin receptorer och det kliniska utfallet in vivo. Vi fann att så var fallet vilket visar att CAMK troligen är en av flera signal-transduktions mekanismer som är aktiva i cerebrovaskulär receptor reglering. Kliniskt skulle man kunna tänka sig att detta kan ha en effekt genom att reducera hjärnskadan efter en stroke.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Slutsats&lt;br/&gt;&lt;br&gt; CAMK har en nyckel roll i kontraktion hos glatta muskle celler. CAMK inhibering minskar receptor upreglering vid organ kultur och SAH. Vi tror att denna studie visar på en ny möjlighet för framtidens forskning och behandling av patienter som drabbas av cerebral ischemia.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/efac81fd-52bc-45d0-baab-c4bc945a7cba</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>CAMK</topic> <topic>Ednothelin receptors</topic> <topic>Calcium</topic> <topic>gene regulation</topic> </subject> <subject authority="lup"> <topic>Infectious Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-69-3</identifier> <identifier type="oldLupId">1789996</identifier> <part> <detail type="volume"> <number>2011:20</number> </detail> <extent unit="pages"> <total>120</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-03-17T09:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Although new methods of treatment are being developed, there is still a need for more effective pharmacological forms of treatment. The aim of this work was to develop an appropriate animal model of retinal ischaemia in which the intracellular signalling pathways involved in the development of retinal injury and neovascularization can be studied in the future. &lt;br/&gt;&lt;br&gt; The pig retina was used as it has a morphology and blood supply similar to those of humans. Two different approaches to inducing experimental retinal ischaemia were developed. In Study I, intraocular pressure was elevated, and in Study II, III and IV, an endovascular approach was used to access the retinal vasculature in order to achieve arterial occlusion. The eyes were analysed using indirect ophthalmoscopy, multifocal ERG with fundus imaging, fluorescence angiography and conventional angiography. The porcine model of pressure-induced retinal ischaemia resulted in multifocal ERG changes typical of retinal ischaemia although there may be a confounding problem of pressure-induced damage. Multifocal ERG may be a useful tool to evaluate retinal dysfunction after an ischaemic injury. The retinal circulation could be accessed by transfemoral endovascular catheterization, and the afferent arteries could be occluded using a balloon catheter for temporary occlusion, and a liquid embolic agent or coiling for permanent occlusion. The degree of ischaemia depended on the location of the occlusion. Occlusion of the proximal part of the ophthalmic artery caused little or no ischaemic effect, presumably due to collateral blood supply. Coiling of the distal parts of the ophthalmic artery caused more pronounced ischaemia. Angiographic evidence was found that blood supply to the pig retina may indeed be both ipsilateral and contralateral, due to an interconnecting artery between the eyes. Taken together, the results of this work represent a step in the development of experimental models of retinal ischaemia.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Näthinnan (retina) ligger längst bak i ögat och fungerar som filmen i en kamera. Stavar och tappar registrerar ljus och signalen går via nerver till syncentra i hjärnan. Blodkärl löper genom näthinnan och förser cellerna med syre och näring samt transporterar bort slaggprodukter. Kärlsjukdomar, som t.ex. diabetes, blodproppar i näthinnan till följd av åderförkalkning och högt blodtryck kan skada näthinnan och resultera i synnedsättning eller blindhet. Vid diabetes blir blodkärlen sköra och kan börja läcka. Vid åderförkalkning bildas blodproppar som kan fastna i ögats blodkärl. Om blodkärlen i ögat läcker eller om blodflödet stoppas får inte näthinnan den mängd syre och näring som den behöver och man får syrebrist i näthinnan, s.k. retinal ischemi. Vid retinal ischemi sätts ett lokalt signalsystem igång för att nybilda blodkärl i näthinnan. De nya blodkärlen fungerar inte optimalt, utan växer onormalt och läcker vilket kan leda till synnedsättning. Retinal ischemi är en av de vanligaste orsakerna till blindhet i världen. Vanligtvis behandlar man näthinnan hos dessa patienter med laser. Laserbehandling förhindrar nybildningen av blodkärl, men är en grov metod som slår ut stora delar av näthinnan och påverkar synfältet och mörkerseendet. Nyligen har det kommit läkemedel som blockerar de signalvägar som stimulerar nybildningen av blodkärl i näthinnan, s.k. VEGF-hämmare. Vi tror att det finns stora möjligheter att finna nya och kompletterande läkemedel för att bromsa nybildning av blodkärl i näthinnan på ett mer effektivt sätt. Forskning om de signalvägar som är involverade i utvecklingen av skada efter retinal ischemi går snabbt framåt vad gäller stroke och hjärtinfarkt, som är ischemiska tillstånd i andra delar av kroppen. Vi vill applicera den kunskapen på ischemiska tillstånd i ögat.&lt;br/&gt;&lt;br&gt; Det övergripande målet med vårt forskningsprojekt är att upptäcka nya behandlingsmetoder för retinal ischemi. Det specifika syftet med denna avhandling är att skapa retinal ischemi på grisar där skadan på näthinnan så mycket som möjligt liknar den skada som uppkommer hos patienter. På dessa grisar med retinal ischemi kan man sedan kartlägga de cellulära signalsystem som är involverade i utvecklingen av skadan på näthinnan och kärlnybildningen till följd av retinal ischemi.&lt;br/&gt;&lt;br&gt; Vi har undersökt två olika metoder för att hindra blodflödet till näthinnan och på så sätt skapa retinal ischemi och en skada på näthinnan som liknar den hos människor. I Studie I använde vi en modell med förhöjt ögontryck för att stänga av blodtillförseln till ögat. I Studie II, III och IV använde vi en kateter som vi under röntgengenomlysning förde upp från ett kärl i ljumsken på grisen och hela vägen till ögats kärl och där stoppade till blodtillförseln till näthinnan.&lt;br/&gt;&lt;br&gt; Med ERG kan man mäta funktionen i näthinnan och den skada som uppstår till följd av ischemi. Man mäter den elektriska ström som uppstår när näthinnans celler aktiveras av ljus. När näthinnans celler skadas av ischemi så minskar denna ström. Hittills har man använt fullfälts-ERG för att mäta ischemisk skada i näthinnan. Med fullfälts ERG mäter man den totala strömmen som genereras i näthinnan vid aktivering av ljus. Vi har i våra studier använt multifokalt ERG, vilket är en vidareutveckling av fullfälts-ERG. Med multifokalt ERG mäter man strömmen i många punkter i näthinnan och kan på så sätt få fram en karta över hur näthinnan aktiveras av ljus. Man kan även se varifrån i näthinnan signalen kommer ifrån, och således kan man bestämma vilken del av näthinnan som skadats. Multifokalt ERG har använts i olika djurstudier, mestadels i primater (apor) och gnagare. I Studie I skapade vi retinal ischemi på grisar genom att höja ögontrycket med en vätskeinjektion i ögat. Vi använde mfERG för att mäta skadan som uppkom i näthinnan till följd av ischemi. Resultaten visar att högt tryck i ögat ger förändringar i multifokalt ERG som är typiska för retinal ischemi. Multifokalt ERG kan vara en användbar metod för att utvärdera och övervaka lokal skada i näthinnan till följd av ischemi.&lt;br/&gt;&lt;br&gt; Ett problem med att studera ischemi till följd av högt tryck i ögat är att man troligen inte bara får skador av blodbristen utan även av trycket. Syftet med Studie II var att skapa en mer renodlad djurmodell för retinal ischemi där skadan i näthinnan bara beror på blodbristen. Med hjälp av röntgengenomlysning letade vi oss upp in i kärlsystemet, från ljumsken och hela vägen till ögats blodkärl, med en kateter. En uppblåsbar ballongkateter användes för att stänga av (ockludera) det stora kärlet som leder till ögat (oftalmicaartären) tillfälligt. Ett lim (Onyx®) injicerades genom en injektionskateter för att stänga av de mindre kärlen som leder till ögat permanent. I gris heter dessa kärlen ”the main ciliary arteries”. Ocklusion i oftalmicaartären ledde till en mild ischemi i näthinnan, förmodligen på grund av att andra kärlsystem då kan förse ögat med blod genom att ansluta sig bortom ocklusionen. Ocklusion i ”the main ciliary arteries” orsakade fullständig ischemi. I Studie II var vi först i världen med att i gris nå hela vägen fram till ögats blodcirkulation med en kateter och att vi där kunde ockludera blodkärlen för att skapa retinal ischemi.&lt;br/&gt;&lt;br&gt; I Studie II gav ballongocklusion en för mild ischemi och limmet var svårt att reglera och det blev en stor variation i graden av ischemi. Syftet med Studie III var att vidareutveckla tekniken i Studie II med hjälp av s.k. ”coiling”. En coil är en liten metalltråd om man skjuter in i blodkärlet. Coilen har en förutbestämd tredimensionell struktur och blir ett nystan när den kommer ut i blodkärlet. I nystanet koagulerar blodet och kärlet täpps till. Man använder coiling på kliniken för att bl a täppa till aneurysm (artärbråck) i hjärnan. Vi ville undersöka om coiling kan användas för att stänga av blodtillförseln till näthinnan och om man kan framkalla olika grader av ischemi genom att ockludera kärlet på olika avstånd från näthinnan. Hypotesen var att coiling kunde vara en lämplig teknik eftersom man kan bestämma platsen på vilken man sätter coilen med stor precision. Resultaten visade att graden av ischemi är relaterat till avståndet mellan ocklusionen och näthinna. Coiling i oftalmicaartären, långt från ögat, orsakade ingen eller liten ischemi, medan coiling i oftalmicaartären, nära ögat, orsakade en mer uttalad ischemi.&lt;br/&gt;&lt;br&gt; Trots den precision med vilken vi kunde placera coilen i kärlen så var variationen i graden av ischemi stor. Intressant nog så började vi i slutet av Studie III få klart för oss att det nog fanns ett blodflöde som gick mellan ögonen. Syftet med Studie IV var att undersöka detta närmare. På röntgen av blodkärlen kunde vi se ett kärl som gick från ena ögonartären till den andra. Om vi stängde av blodflödet till ena ögat så tror vi att funktionen i näthinnan på andra ögat påverkas. Denna upptäckt förklarar troligen den stora variationen i graden av retinal ischemi som vi får när vi ockluderar de tillförande kärlen och har betydelse för den fortsatta utvecklingen av denna djurmodell av retinal ischemi.&lt;br/&gt;&lt;br&gt; Vi hoppas att genom dessa studier ha tillfört kunskap om djurmodeller för retinal ischemi. På sikt hoppas vi få en stabil djurmodell för retinal ischemi och i denna hitta nya intressanta cellulära signalvägar som aktiveras av retinal ischemi och ta fram läkemedel mot dessa. Om man har en bra djurmodell så kan man undersöka läkemedlets effekt mot den skada och nybildning av blodkärl som uppkommer till följd av retinal ischemi. Först därefter kan man pröva dessa läkemedel på patienter med t.ex. diabetes och blodproppar i näthinnan. Förhoppningen är att hindra synnedsättning och blindhet till följd av retinal ischemi.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/33d9d735-91e6-45c6-a8c9-4bd73e5bd36f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Dissertation_Hakan_Moren_2013_FINAL.pdf">https://portal.research.lu.se/files/3122656/4124142.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">10203966</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Ophthalmology (Lund), Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>retinal ischemia</topic> <topic>animal model</topic> <topic>multifocal electroretinography</topic> <topic>intraarterial coiling</topic> <topic>retinal vasculature</topic> </subject> <subject authority="lup"> <topic>Ophthalmology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-23-6</identifier> <identifier type="oldLupId">4123542</identifier> <part> <detail type="volume"> <number>2013:148</number> </detail> <extent unit="pages"> <total>108</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-11-29T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>33d9d735-91e6-45c6-a8c9-4bd73e5bd36f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:02:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:02:16+02:00</recordDateApproved> </recordInfo> </mods>

Especially, proton-exchange membrane fuel cells (PEMFCs) have been intensively developed during the last decade because of their wide application windows including various portable, stationary and transportation applications. The market has been and will be mainly driven by the automotive manufacturers that announced their commercialization of fuel cell vehicles in 2015. A key for success of the fuel cell market is the performance, durability and cost of the PEMFC components. Importantly, polymer membrane plays a key role at the heart of the system to decide much of the performance and durability of PEMFCs. State-of-the-art perfluorosulfonic acid (PFSA) membranes such as Nafion® developed by DuPont are today the most widely employed membrane material in PEMFC applications, because of their high performance and durability. However, PFSA membranes typically show some limitations for commercialization, and the main drawback are the high material cost and environmentally unfriendliness due to their perfluorinated structure. This has motivated an intensive research over the past decade for alternative membrane based on inexpensive and environmentally-friendly materials.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The thesis work focused on extensive study of the preparation of hydrocarbon (HC) membranes with high performance and durability, based on the engineering polymers with high thermal/chemical/mechanical stabilities combined with low cost and environmental friendliness. The first part of the thesis gives a general description of fuel cells, a review of the current development of HC polymers and a brief summary of the the six research articles whose details are covered by the second part of the thesis. The important synthetic strategies applied in the thesis work are 1. the use of fully aromatic backbones based on polysulfones, 2. The incorporation of densely sulfonated units in the polymers, 3. The placement of the acidic groups in ortho-to-sulfone positions. The first point is to enhance the characteristic features of the HC polymers in relation to PFSAs. The second is to improve the proton conductivity and dimensional stability. In addition, the last is to give the most chemical stable acidic group among the HC polymers.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In summary, some of the polymers obtained in the thesis gave quite comparable proton conductivities to that of PFSAs. One outstanding finding is that the polymers showed a higher proton conductivity than that of PFSAs at cold climate. The polymers were also found to possess a very high resistance towards the decomposition of the acidic groups. Finally, a new concept, microblock copolymers, was suggested as potential candidates for ion-exchange membrane applications towards commercialization because of the cost performance and straight-forward preparation, in addition to the performance and durability.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Fuel cells have been considered as alternative power source to petroleum oil. Especially, fuel cells have potentials to provide no pollutant emission (e.g., CO2, NOx, SOx) out of the power generation. For instance, once the fuel cells are installed instead of combustion engine in the cars used for commuting, transportation and leisure, the amount of pollutant emission causing the global warming will be significantly reduced. One important indication to the market of fuel cells is that automotive manufacturers announced their commercialization of fuel cell vehicles in 2015, using proton-exchange membrane fuel cells (PEMFCs). Importantly for Scandinavian countries, Honda, Nissan, Toyota and Hyundai have all joined in signing the project with hydrogen infrastructure companies and Nordic NGOs which plans the market introduction of fuel cell vehicles and hydrogen refuelling infrastructure during the period 2014-2017.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A key for success of the fuel cell market is the performance, durability and cost of the used material components. Importantly, polymer membrane plays a key role as the central to dominate the performance and durability of PEMFCs. State-of-the-art perfluorosulfonic acid (PFSA) membranes such as Nafion® developed by DuPont are today the most widely employed membrane material in PEMFC applications, because of their high performance and durability. However, PFSA membranes typically show some limitations for commercialization, and the main are the expensive material cost and environmentally unfriendliness due to their fluorinated structure. This has motivated an intensive research over the past decade for alternative membrane based on inexpensive and environmentally-friendly materials. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Then, the engineering plastics, the thermally/chemically/mechanically stable polymer materials with cheap potential cost and environmentally friendliness, are intensively investigated as alternatives to PFSAs for membrane applications including not only fuel cells, but also desalination by reverse osmosis to purify water for drinking, gasification via electrolyte to produce fuel gases H2/O2 out of water and vanadium redox flow batteries for energy storage. In fact, the performance of such materials is still inferior to that of the PFSA membranes in terms of the membrane performance and durability. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Therefore, the thesis work focused on extensive study of the preparation of polymers with high performance and durability. As a result, the polymers gave quite comparable proton conductivities to that of PFSAs. One remarkable finding is that they have potentials to perform over 10 times as much as that of PFSAs at cold climate. They were ultimately designed to give the most stable chemical property in relation to any conventional HC polymer. Finally, a new concept, microblock copolymers, was suggested as potential candidates for ion-exchange membrane applications towards commercialization in light of cost performance and reliable production, in addition to performance and durability.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e7cca840-4f06-4f90-b5c7-74e642cd3ed3</url> </location> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>polymer electrolytes</topic> <topic>sulfonations</topic> <topic>polycondensation</topic> <topic>polyaromatics</topic> <topic>ionomers</topic> <topic>sulfonated monomers</topic> <topic>block copolymers</topic> <topic>segmented copolymers</topic> <topic>sequenced copolymers</topic> <topic>poly(arylene ether sulfone)s</topic> <topic>lithiations</topic> <topic>sulfinations</topic> <topic>metalations</topic> <topic>phase-separation</topic> <topic>highly sulfonations</topic> <topic>macromonomers</topic> <topic>blocky structures</topic> </subject> <subject authority="lup"> <topic>Chemical Sciences</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7422-311-8</identifier> <identifier type="oldLupId">3164307</identifier> <part> <extent unit="pages"> <total>69</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-12-03T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>e7cca840-4f06-4f90-b5c7-74e642cd3ed3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:02:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:02:19+02:00</recordDateApproved> </recordInfo> </mods>

In medical image analysis segmentation has a great clinical value since the aim could be to localize organs or pathologies in order to raise the quality of diagnoses. This thesis consists of three papers where different segmentation techniques have been applied to different imaging modalities. In the first paper a full computer assisted diagnosis system is presented where the aim is to find abnormal lesions in scintigraphy images of the kidneys. Here we have two segmentation parts; first segmentation of each kidney in the images using an active shape model and then localization of potential lesions using thresholding. In a test group of 56 patients the segmentations work very well just like the classification of lesions does. The second application is segmentation of the left ventricle in echocardiographic images. This segmentation is important when measuring the left ventricular function. The segmentation is done using a region based snake where the data term is driven by virtual image forces derived from the image intensities. To overcome problems with the cardiac valve opening and closing during the cardiac cycle, we annotate two anchor points, one on each side of the valve. We track these through the cycle in order to minimize user interaction and no segmentation is done over the valve. This method shows promising results. In the third paper we have developed a measure of the shape of the septum, the wall between the left and the right ventricle, to be used in echocardiographic images of patients with a mechanical pump attached to their heart as a bridge to transplantation. Such a measure can be useful when tuning the speed of the pump. Here the segmentation of the septum is achieved using the shortest path algorithm. The septum measure is then a measure of how much it deviates from a straight septum. Our septum measure corresponds in most cases to the assessments from a physician. These three applications show the usefulness of segmentation in a variety of applications within medical imaging.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ef27baa5-d1b5-4399-86db-bdceaa9b12bd</url> </location> </relatedItem> <originInfo> <publisher>Centre for Mathematical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Mathematical Sciences</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-826-1 (pdf)</identifier> <identifier type="isbn">978-91-7473-825-4 (print)</identifier> <identifier type="oldLupId">4360371</identifier> <identifier type="other">LUTFMA-2037-2013</identifier> <part> <extent unit="pages"> <total>73</total> </extent> </part> </relatedItem> <recordInfo> <recordIdentifier>ef27baa5-d1b5-4399-86db-bdceaa9b12bd</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:02:25+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:02:25+02:00</recordDateApproved> </recordInfo> </mods>

In this thesis, schemes to control the generation of attosecond pulses and pulse-shaping techniques to compress the pulses are presented.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Generation of attosecond pulses requires high intensity, which is reached by focusing a pulsed femtosecond laser. The emitted pulses come isolated or in an attosecond pulse train (APT), depending on the duration of the driving field. In several experiments, we have controlled the pulse repetition rate in the APT by adding the second harmonic to the driving field. An APT with one pulse per cycle of the driving field is then generated, instead of a train with two pulses per cycle, which is the case for a one-color field. A rather strong second harmonic changes the shape of the generating field, which leads to a tunable central photon energy of the attosecond pulses. With a short driving field an APT containing few pulses is generated. The spectrum of a short APT shows additional interference structures. In analogy with multi-slit interference, these structures are secondary maxima, positioned in between the principal maxima. The number of secondary maxima is related to the number of pulses in the APT. Attosecond pulses are emitted by a macroscopic medium. How the macroscopic conditions affect the pulse duration has also been studied.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Directly after the generation the attosecond pulses have, in general, a relatively long pulse duration. Spectral filtering is important to shape the spectrum and compress the pulses. We have used thin transmission filters and multi-layer XUV-mirrors for filtering. We measured a pulse duration of 130 as, for attosecond pulses generated in Ne and filtered by Zr.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Most schemes to characterize attosecond pulses are based on a cross-correlation with an IR field. We have used the RABITT (reconstruction of attosecond beating by interference of two-photon transitions) and the AC-streak camera techniques, capable of measuring different types of APT:s. &lt;br/&gt;&lt;br&gt; Finally, attosecond pulses have been used in two application experiments: Momentum shearing interferometry; and the Quantum stroboscope, where electron scattering off the atomic potential was observed.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/70cc2e92-93d8-49b8-b306-19ac75d6b765</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Mansten2009.pdf">https://portal.research.lu.se/files/3124664/2370399.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">16378403</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Physics, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Pulse characterization</topic> <topic>Spectral signature</topic> <topic>Two-color generation</topic> <topic>Pulse compression</topic> <topic>Attosecond pulse trains</topic> <topic>High-order harmonics</topic> <topic>Pulse shaping</topic> <topic>Tunable</topic> <topic>Fysicumarkivet A:2009:Mansten</topic> </subject> <subject authority="lup"> <topic>Atom and Molecular Physics and Optics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Reports on Atomic Physics</title> </titleInfo> <identifier type="issn">0281-2762</identifier> <identifier type="isbn">978-91-628-7756-9</identifier> <identifier type="oldLupId">1367287</identifier> <part> <detail type="volume"> <number>LRAP-406</number> </detail> <extent unit="pages"> <total>178</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-04-24T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>70cc2e92-93d8-49b8-b306-19ac75d6b765</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:02:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:02:31+02:00</recordDateApproved> </recordInfo> </mods>

It is considered that children can regain better sensory and motor function after a peripheral nerve injury, but the exact mechanism behind such superior recovery is not known.&lt;br/&gt;&lt;br&gt; The aim of the thesis was to study the long-term clinical outcome after a peripheral nerve injury in patients injured in childhood and adolescence and to relate the clinical outcome to changes in the central and peripheral nervous systems. In addition, the consequences of the nerve injury for the patient´s life were explored. A short-term pilot study with four patients showed remaining clinical and electrophysiological abnormalities and functional Magnetic Resonance Imaging (fMRI) showed that the cerebral activation pattern after tactile stimulation of the injured hand was different compared to the pattern of the healthy hand. In a larger study, the long-term functional outcome after nerve repair in those injured in childhood was compared to the outcome of those injured in adolescence. Patients below the age of 21 years, operated on at our hospital for a complete median or ulnar nerve injury at the level of the forearm 1970-1989, were followed up at a median of 31 years. Outcome was significantly better in those injured in childhood, i.e. below the age of 12 years, with almost full sensory and motor recovery. No significant differences in recovery were seen between patients with median and ulnar nerve injuries, or even when both nerves were injured. The median DASH scores (i.e. questionnaire; Disability Arm Shoulder and Hand) were within normal limits and cold sensitivity was not a problem in either age group. Those injured in adolescence (i.e. above the age of 12 years) had a significantly higher impact on their profession, education, and leisure activities. Electrophysiological evaluation (amplitude, conduction velocity and distal motor latency) showed pathology in all parameters and in all patients, irrespective of age at injury. This suggests that the mechanisms behind the superior clinical outcome in children are not located in the peripheral nervous system. With fMRI it was shown that patients injured in childhood had a cortical activation pattern similar to that of healthy controls and it was observed that cerebral changes in both hemispheres may explain differences in clinical outcome following a nerve injury in childhood or adolescence. Finally, fifteen patients injured in adolescence, who were interviewed to explore the experiences after a nerve injury and its consequences for daily life, described emotional reactions to trauma. Even symptoms related to post-traumatic stress disorder were mentioned and the patients described different adaptation strategies used. Educational and professional life had changed completely for some. &lt;br/&gt;&lt;br&gt; The present thesis shows that age is an important factor that influences outcome after a peripheral nerve injury. The reason for the age-related difference in outcome is alterations in the central nervous system. In addition, a nerve injury had a severe impact on the individuals´ life. By further exploring the mechanisms of plasticity and by modifying the rehabilitation, we might eventually improve the outcome after a peripheral nerve injury.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1309efbf-0fc9-4985-b86f-033d2cd7bfed</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Chemnitz.pdf">https://portal.research.lu.se/files/3125339/4068029.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3143099</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Hand Surgery Research Group</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-80-2</identifier> <identifier type="oldLupId">4057406</identifier> <part> <detail type="volume"> <number>2013:108</number> </detail> <extent unit="pages"> <total>63</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-10-11T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>1309efbf-0fc9-4985-b86f-033d2cd7bfed</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:02:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:02:43+02:00</recordDateApproved> </recordInfo> </mods>

The first paper investigates an alternative state space parametrization for use with the Kalman filter approach to simultaneous localization and mapping, and shows it has superior convergence properties compared with the state-of-the-art. The second paper presents a continuous optimization method for mobile robot path planning, designed to minimize the uncertainty of the geometry reconstructed from images taken by the robot. Similar concepts are applied in the third paper to the problem of sequential 3D reconstruction from unordered image sequences, resulting in increased robustness, accuracy and a reduced need for costly bundle adjustment operations. In the final paper, a method for efficient solution of bundle adjustment problems based on a junction tree decomposition is presented, exploiting the sparseness patterns in typical structure-and-motion input data.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d7973e55-8882-404a-b954-7e6fceea90ec</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis.pdf">https://portal.research.lu.se/files/3126457/4986232.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7034111</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Centre of Mathematical Sciences</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Computer graphics and computer vision</topic> <topic>Mathematical Sciences</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-371-6</identifier> <identifier type="oldLupId">4986230</identifier> <identifier type="other">LUTFMA-2034-2012</identifier> <part> <extent unit="pages"> <total>88</total> </extent> </part> </relatedItem> <recordInfo> <recordIdentifier>d7973e55-8882-404a-b954-7e6fceea90ec</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:03:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-13T09:56:38Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:03:00+02:00</recordDateApproved> </recordInfo> </mods>

In addition, HSCs are able to undergo self-renewing divisions whereby new HSCs are produced. This is an extremely important feature of HSCs in order to ensure the existence of the HSC pool that is paramount to provide life-long hematopoiesis. Aging is in general characterized by reduced ability to sustain tissue homeostasis and return to a homeostatic state after stress or trauma. Several alterations arise in the hematopoietic system with advancing age and several of these have been suggested to originate at the level of HSCs. With advancing age a bias toward myeloid cells arises within the hematopoietic system characterized by a reduced production of lymphoid cells. Despite an accumulation of HSCs in aged mice it has been suggested that aged HSCs display a decreased proliferation that depends on p16Ink4a activity. Although we observed (article I) a decreased replicative activity in physiologically aged HSC we found no evidence for increased p16Ink4a activity in these cells. In article II we demonstrated several hematopoietic defects reminiscent of premature HSC aging including anemia, lymphopenia, and myeloid lineage skewing in mice that rapidly accumulate mitochondrial DNA (mtDNA) mutations. This however, was due to distinct differentiation blocks and/or disappearance of downstream progenitors in the absence of several hallmarks of physiological HSC aging such as epigenetic alterations and accumulation of a myeloid biased subset of HSCs. These findings highlight the necessity of intact mitochondrial function for multilineage hematopoiesis but argue against mtDNA mutations as primary drivers of HSC aging. How growth factors and the relevant signaling pathways dictate HSC lineage specification is not fully understood. Aged mice, deficient in the signal adaptor protein LNK (article III), that acts to dampen several extrinsic signaling pathways, did not display repopulating defects otherwise observed in physiologically aged HSCs. This argues that enhanced cytokine signaling can counteract several key aspects of age-associated HSC decline.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Blodet är sammansatt av många olika typer av mogna celler som är ansvariga för specialiserade roller inom blodsystemet. Röda blodceller transporterar syre till kroppens celler, vita blodceller förser oss med försvar mot mikroorganismer och blodplättar ser till att stoppa blödningar. Nybildning av blodceller behövs kontinuerligt eftersom vissa celler lever bara i några dagar medan andra kan leva i månader eller år. Dessutom när vi blir sjuka eller blöder då uppstår det ett ändrat behov av mogna celler som blodsystemet måste kunna svara omedelbart på. Var kommer alla de mogna cellerna i blodet ifrån? Det finns en väldigt sällsynt celltyp, som sitter i benmärgen och kallas för blodbildande (hematopoetiska) stamceller (HSC). HSC har den unika förmågan att kunna ge upphov till alla blodceller (differentiering) och dessutom att skapa en exakt kopia av sig själv i en process kallad självförnyelse. För att kunna skapa mogna celler då genomgår HSC en differentieringsprocess som i början ger upphov till olika stadier av allt mognare celltyper som succesivt förlorar förmågan att bilda de olika blodcellerna tills slutligen en viss mogen blodcells har skapats. Att HSC kan självförnyas, försäkrar att HSC kan stå för blodbildning livet ut. Men det finns ett problem. När vi blir äldre ökar risken för vissa blodrelaterade sjukdomar, bland annat cancer och dessutom minskar blodets förmåga att kämpa emot infektioner. Dessa åldersrelaterade ändringar i blodet tror man kan vara orsakade av förändringar i de blodbildande stamcellerna. Denna avhandling är fokuserad på molekylära mekanismer som tros kunna orsaka åldersrelaterade förändringar i HSC funktion.&lt;br/&gt;&lt;br&gt; Trots att antalet HSC ökar i åldrande möss har det hävdats att gamla HSC inte delar sig lika ofta som unga. Ökad aktivitet av ett celldelnings hämmande protein p16, har föreslagits orsaka denna egenskap samt att vissa gamla HSC delar sig inte alls. I artikel I i denna avhandling undersökte vi aktiviteten av p16 i HSC från normalt åldrade möss. Vi kom fram till att trots gamla HSC delar sig inte lika ofta som unga HSC har de en omfattande celldelnings förmåga och samtidigt kunde vi inte hitta något bevis på p16 aktivitet i gamla HSC.&lt;br/&gt;&lt;br&gt; I våra celler finns olika organeller och en av de, mitokondrier, förser celler med bland annat molekyler (ATP) vilka används som energikälla för att driva diverse cellulära processer. Mitokondrier har sitt eget DNA (mtDNA) och uppsamlad skada på det leder till uppkomst av olika kropps och cellulära förändringar i möss som vanligt vis kopplas till åldrande. I artikel II undersökte vi om förändringar som uppstår i blodet, på grund av ökad frekvens av mtDNA skada, orsakas av tidigt åldrande av HSC. Vi kom fram till att intakt funktion av mitokondrier är nödvändig för normal blodbildning men att mtDNA skada på egen hand driver inte åldrande av HSC.&lt;br/&gt;&lt;br&gt; I artikel III har vi analyserat stamcellsfunktion i möss som saknar genen LNK, vilken är involverad i omvandling av signaler från signalmolekyler (cytokiner). HSC från normala gamla möss visade flera funktionella defekter medan gamla HSC som saknar LNK förvånande uppförde sig som unga stamceller. Dessa resultat ger därför en viktig insikt i vilka mekanismer är involverade i att bevara stamcellfunktion i blodsystemet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d9b2b4d2-9a8a-4886-8ac3-1a130c5e518b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Gudmundur_Norddahl_Kappa.pdf">https://portal.research.lu.se/files/3129604/2224241.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">10621342</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Section for Immunology, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-64-2</identifier> <identifier type="oldLupId">2224236</identifier> <part> <detail type="volume"> <number>2012:2</number> </detail> <extent unit="pages"> <total>136</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-01-20T10:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

All patients had continuous follow-up until healing or death, irrespective of the vascular intervention.&lt;br/&gt;&lt;br&gt; In total (n=1,151), 36% of patients healed primarily, 16% healed after minor amputation, 13% healed after a major amputation, and 27% died unhealed. At the end of the study, there was a dropout rate of 5%, and 3% of patients were still in treatment. In patients considered not feasible for revascularization (n=602), 38% healed primarily, 12% healed after minor amputation, 17% healed after major amputation, and 33% died unhealed. Comorbidities, the severity of PAD, and the extent of tissue involvement were strongly related to a low probability for ulcer healing, irrespective of revascularization. Angioplasty or reconstructive vascular surgery increased the probability of healing. The time to revascularization after admittance to a diabetic foot centre was also related to the probability of healing without major amputation.&lt;br/&gt;&lt;br&gt; After healing from a previous ischaemic ulcer, 34% of patients developed a new ulceration in the same foot within the observation time. Twenty-two percent of patients who developed new ulcers had an amputation before healing from the new ulcers. Lesser maximal tissue destruction during the previous ulcer and open reconstructive vascular surgery were related to a lower risk of new ulcerations. Patients with diabetes and ischaemic foot ulcers had a median survival time of 33 months.&lt;br/&gt;&lt;br&gt; In conclusion, this thesis has shown that a substantial number of patients with diabetes, foot ulcers, and severe PAD can heal without a major amputation. The probability of ulcer healing was strongly related to comorbidity, the extent of tissue involvement, and the severity of PAD. Patients with diabetes and ischaemic foot ulcers not feasible for revascularisation are not excluded from healing without major amputation. Not only revascularization per se, but also the timing of revascularization increased the probability of healing without a major amputation. Following healing, these patients had a high risk of developing new ulcers. The extent of tissue involvement of a previous ulcer and reconstructive vascular surgery affected the risk of developing new ulcers.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Syftet med de fyra delarbeten som presenteras i denna avhandling var att studera dels utfall av fotsår samt identifiera faktorer relaterade till utfall och dels risken för att utveckla nya sår efter läkning av tidigare sår hos patienter med diabetes, fotsår och uttalad perifer kärlsjukdom.&lt;br/&gt;&lt;br&gt; Patienter med diabetes och fotsår med ett systoliskt tåtryck &amp;lt;45 mmHg eller ett ankeltryck &amp;lt;80 mmHg som uppsökte och behandlades av ett multidisciplinär diabetes fotteam inkluderades prospektivt och behandlades enligt ett vårdprogram. Alla patienter följdes upp kontinuerligt till läkning eller död oberoende av kärlkirurgisk åtgärd (revaskularisering).&lt;br/&gt;&lt;br&gt; Trettiosex procent av patienterna läkte primärt, 16% efter mindre amputation (amputation genom eller nedom fotleden), 13% efter större amputation (amputation ovanför fotleden) och 27% dog oläkta. Hos patienter utan revaskularisering, läkte 38% primärt, 12% läkte efter mindre amputation, 17% läkte efter större amputation och 33% dog oläkta. Samsjuklighet, svårighetsgraden av perifer kärlsjukdom och graden av sårskada var starkt relaterade till sämre sårläkning oavsett revaskularisering. Tiden från ankomsten till diabetes fotteamet till revaskularisering var också relaterad till sannolikheten för läkning utan större amputation.&lt;br/&gt;&lt;br&gt; Efter läkning av tidigare sår, utvecklade 34% nya sår på samma fot inom observationstiden. Tjugotvå procent av patienter som utvecklade nya sår genomgick en amputation innan de nya såren läkte. Lägre grad av maximal sårskada som förelåg för det tidigare såret, och öppen rekonstruktiv kärlkirurgi, var relaterad till lägre risk för utveckling av nya sår. Patienter med diabetes och fotsår orsakat av nedsatt cirkulation hade en medianöverlevnad på 33 månader.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar denna avhandling att hos patienter med diabetes och fotsår orsakat av nedsatt cirkulation är sannolikheten för sårläkning starkt relaterad till samsjuklighet, graden av sårskada, och svårighetsgraden av perifer kärlsjukdom. Resultatet visar också att fotsår orsakat av nedsatt cirkulation hos patienter med diabetes som inte är tillgängliga för revaskularisering kan läka utan större amputation. Vid nedsatt perifer cirkulation är, förutom revaskularisering, tiden till revaskularisering också viktig för sårläkning utan större amputation. Efter sårläkning, har dessa patienter hög risk för att utveckla nya sår. Graden av tidigare sårskada och rekonstruktiv kärlkirurgi påverkade risken för utveckling av nya sår.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d7092093-9547-4e98-b945-bced698bb90e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Outcome_of_ischemic_foot_ulcer_in_patients_with_diabetes__with_or_without_revascularization.pdf">https://portal.research.lu.se/files/3129728/4612608.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1338623</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Diabetes and Endocrinology</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>outcomes</topic> <topic>PAD</topic> <topic>Diabetic foot ulcers</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-028-9</identifier> <identifier type="oldLupId">4612607</identifier> <part> <detail type="volume"> <number>2014:99</number> </detail> <extent unit="pages"> <total>94</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-09-23T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>d7092093-9547-4e98-b945-bced698bb90e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:03:05+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:03:05+02:00</recordDateApproved> </recordInfo> </mods>

According to evaluation reports, many individuals with persistent mental illness seem to lack meaningful everyday occupations. The aim of this thesis was to investigate possible relationships between occupation, operationalised as time use and daily rhythm in daily activities, among individuals with persistent mental illness and relationships to different aspects of well-being, and identify sociodemographic and clinical risk factors for any imbalance in daily activities. A further aim was to investigate perceived meaningfulness in daily occupations, with a specific focus on work. The thesis is based on four studies. Studies I-III are based on a randomised sample of 103 participants from a psychiatric outpatient unit, and Study IV included 12 participants that were interviewed about perceived meaningfulness in their work. The results showed that spending much time in activities in everyday life, especially in work and other productive activities, and having a beneficial daily rhythm were associated with several factors of well-being. Spending much time asleep, especially at daytime, was associated with worse well-being. Among the risk factors for imbalance in daily activities was having high levels of general symptoms, which explained most of the risk of spending short periods in work/education, having an abnormal time asleep and an adverse daily rhythm. Further, having a diagnosis of schizophrenia meant an increased risk of spending little time in daily activities. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Being occupied per se, as well as having organised activities and routines, was perceived as meaningful and generated a feeling of occupational balance. Further, social life and a feeling of being needed by others was the aspect of meaningfulness most frequently reported in everyday life. Other aspects of meaningfulness in daily occupations were enjoyment, a sense of achievement and doing occupations to take care of oneself to maintain health. Work, in terms of employment, was perceived as meaningful since it had certain unique characteristics, gave structure to the day, a feeling of normality and acceptance, a balanced everyday life, and increased well-being. However, it was important that the demands at work and the individuals’ interests and skills were well matched. A tentative model was suggested, integrating these aspects of meaningfulness in work.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/368e8534-ef64-46e2-ace2-0a13ec02c586</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="leufstadius_kappa.pdf">https://portal.research.lu.se/files/3134600/1149923.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2565267</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Division of Occupational Therapy and gerontology</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>time use</topic> <topic>Persistent mental illness</topic> <topic>meaningful occupations</topic> <topic>occupational balance</topic> <topic>daily activities</topic> <topic>work</topic> <topic>imbalance</topic> <topic>well-being and mental health</topic> </subject> <subject authority="lup"> <topic>Occupational Therapy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-18-7</identifier> <identifier type="oldLupId">1149685</identifier> <part> <detail type="volume"> <number>2008:65</number> </detail> <extent unit="pages"> <total>152</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-06-11T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The&lt;br/&gt;&lt;br&gt; construction sector’s and the critics’ manner of describing these problems fails to a large extent to take into&lt;br/&gt;&lt;br&gt; consideration the way people function in connection with practical problem solving. This is remarkable. People&lt;br/&gt;&lt;br&gt; play a central role in all building activity, their being the ones who experience a need, make demands, commission&lt;br/&gt;&lt;br&gt; work, formulate and solve problems, evaluate results, and the like. Therefore, people need to be included as a&lt;br/&gt;&lt;br&gt; factor in an extended problem description here; the problem solver should be seen as part of the problem.&lt;br/&gt;&lt;br&gt; Theories in psychology and social psychology can be used to identify relevant issues and to support the&lt;br/&gt;&lt;br&gt; management of the human factor in such an extended problem definition.&lt;br/&gt;&lt;br&gt; The research work which has resulted in the present thesis represents an attempt to understand the relationship&lt;br/&gt;&lt;br&gt; between (1) the problems of the construction sector, (2) how the problems tend to be formulated, (3) the problemsolving&lt;br/&gt;&lt;br&gt; strategies that are employed and (4) the problem solver involved. The aim of all of this has been to&lt;br/&gt;&lt;br&gt; develop a methodology able to provide practical support for a given work group in a manner enabling it to make&lt;br/&gt;&lt;br&gt; use of a greater share of its intrinsic and potential problem solving and value-creating capacity than would&lt;br/&gt;&lt;br&gt; otherwise be the case.&lt;br/&gt;&lt;br&gt; In a study of literature that is relevant, and in three separate empirical studies, the construction sector’s problem&lt;br/&gt;&lt;br&gt; panorama and the possibility of creating extended and more effective problem management is investigated. The&lt;br/&gt;&lt;br&gt; one study, involving use of a questionnaire, investigates the relationship between different problems, the work&lt;br/&gt;&lt;br&gt; situation and how people tend to function generally. Another study was carried out as a series of seminars in&lt;br/&gt;&lt;br&gt; which the participants were given the opportunity to increase their understanding of the significance of the human&lt;br/&gt;&lt;br&gt; factor. A third study was carried out within an actual construction project, a small group of site managers being&lt;br/&gt;&lt;br&gt; given, in connection with the ordinary meetings they held at the workplace, the opportunity to increase their&lt;br/&gt;&lt;br&gt; understanding of the significance of the human factor and of the need for more extended problem formulations.&lt;br/&gt;&lt;br&gt; The results presented in the thesis represent a proposal for just such an extended problem formulation and a&lt;br/&gt;&lt;br&gt; methodology for implementing it. The studies carried out show that even those with long experience in the&lt;br/&gt;&lt;br&gt; construction industry can discover new ways of seeing their daily sphere of activity. Implementation of the&lt;br/&gt;&lt;br&gt; methodology involved presupposes the presence of a facilitating interventionist - “the liberator” – whose main&lt;br/&gt;&lt;br&gt; objective is to free the problem solvers from different inhibiting phenomena (mainly psychological) that are&lt;br/&gt;&lt;br&gt; operating in the problem-solving situation. This is done by introducing and leading an initiated dialogue regarding&lt;br/&gt;&lt;br&gt; (1) the specific problems involved, as well as (2) problem solving in general, and (3) the effect of the human factor&lt;br/&gt;&lt;br&gt; on the problem formulation, the problem solving and the decision making to be carried out.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/dbe2bb86-8a5f-44c6-83b0-1faa9dbda53d</url> </location> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Problem solving.</topic> <topic>Human behavior and psychology</topic> <topic>Information distortion</topic> <topic>Problem formulation</topic> <topic>Action research</topic> <topic>Behavioral Change</topic> <topic>Collaboration</topic> <topic>Construction sector</topic> </subject> <subject authority="lup"> <topic>Construction Management</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-85257-13-3</identifier> <identifier type="oldLupId">8522296</identifier> <part> <extent unit="pages"> <total>338</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-02-11T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>dbe2bb86-8a5f-44c6-83b0-1faa9dbda53d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:03:21+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:03:21+02:00</recordDateApproved> </recordInfo> </mods>

Using baseline (1991-1994) and longitudinal (register- and reinvestigation-based) data from MDC-CC (partly re-investigated 15.8 years later (n=2345)) we examined the association of increasing quartiles of copeptin (lowest quartile as reference) with prevalent diabetes (DM) and other components of the metabolic syndrome (MetS) at baseline, and incident DM, measures of obesity and microalbuminuria at follow up, using multivariable logistic regression. After adjusted for clinical and anthropometric risk factors, cystatin C, and C-reactive protein, increasing copeptin quartile (lowest quartile as reference) was associated with prevalent DM (Ptrend=0.04). Furthermore, copeptin quartile was after adjustment for age, sex, insulin and diabetes mellitus associated with prevalent hypertension (Ptrend=0.004), abdominal obesity (Ptrend=0.002), obesity (P=0.01), top quartile of CRP (Ptrend=0.007) and MetS (adjusted for age and sex only) (Ptrend&amp;lt;0.001). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; During 12.6 years of register-based follow up 174 subjects (4%) developed new-onset diabetes. The odds of developing DM increased across increasing quartile of copeptin, even after additional adjustment for baseline fasting glucose and insulin (adjusted odds ratios 1.0, 1.37, 1.79, and 2.09; Ptrend =0.004). The association with incident DM remained significant in analyses restricted to subjects with fasting whole blood glucose &amp;lt;5.4 mmol/L at baseline (adjusted odds ratios 1.0, 1.80, 1.92, and 3.48; Ptrend=0.001). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; When incident cases of DM were captured by a re-examination (n=2345) 15.8 years after baseline, increasing copeptin quartiles predicted DM (odds ratios 1.18, 1.32, 1.46; Ptrend=0.04), abdominal obesity (odds ratios 1.55, 1.30, 1.59; Ptrend=0.04), and microalbuminuria (odds ratios 1.05, 1.08, 1.65, Ptrend=0.02) but not MetS (Ptrend=0.19) after adjustment for age, gender and all MetS components at baseline.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Genetic polymorphisms in the human AVP receptor 1a gene (AVPR1A) and 1b gene (AVPR1B) were genotyped in MDC-CC. We found that genetic variance in AVPR1A was associated with high glucose and low triglyceride levels, as well as increased prevalence of DM in subjects with a high fat intake, features strongly resembling mice with selective deletion of the same receptor. Finally, we found that genetic variance in AVPR1B was associated with BMI. This finding was replicated in the MDC replication cohort (n=24344).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Conclusion: Elevated copeptin independently predicts DM and abdominal obesity but not the cluster of MetS. Our findings suggest a relationship between a dysregulated vasopressin system and cardiometabolic risk, which could have implications for risk assessment and novel preventive treatments.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/be10fa0d-8e87-45aa-9f87-dc110e175313</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="EnhAPrning_dissertation.pdf">https://portal.research.lu.se/files/3135618/3195270.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2030730</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Hypertension and Cardiovascular Disease</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>arginine vasopressin</topic> <topic>copeptin</topic> <topic>prediction</topic> <topic>epidemiology</topic> <topic>diabetes mellitus</topic> <topic>risk factors</topic> <topic>abdominal obesity</topic> <topic>obesity</topic> <topic>metabolic syndrome</topic> <topic>microalbuminuria</topic> <topic>AVPR1A</topic> <topic>AVPR1B</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-63-0</identifier> <identifier type="oldLupId">3193890</identifier> <part> <detail type="volume"> <number>2012:100</number> </detail> <extent unit="pages"> <total>140</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-12-14T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>be10fa0d-8e87-45aa-9f87-dc110e175313</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:03:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:03:30+02:00</recordDateApproved> </recordInfo> </mods>

The causes of RA remain largely unknown, but considerable&lt;br/&gt;&lt;br&gt; evidence suggests a multifactorial aetiology involving both environmental and genetic&lt;br/&gt;&lt;br&gt; factors. Large efforts have been directed towards the understanding of the molecular&lt;br/&gt;&lt;br&gt; mechanisms underlying RA. Because of the complexity of the disease in humans,&lt;br/&gt;&lt;br&gt; animal models for RA have become attractive tools for gene-identification. Use of&lt;br/&gt;&lt;br&gt; such models not only overcomes genetic complications, but it also permits studies&lt;br/&gt;&lt;br&gt; under stable environmental conditions. However, so far genetic studies using animals&lt;br/&gt;&lt;br&gt; have had only limited success. In fact, researchers have encountered significant&lt;br/&gt;&lt;br&gt; difficulties in the analysis of complex traits.&lt;br/&gt;&lt;br&gt; The first part of this thesis is summarizing two major problems we have faced in the&lt;br/&gt;&lt;br&gt; past years. In the first study we investigated the genetic setup and the response&lt;br/&gt;&lt;br&gt; towards various arthritis models of two DA rat substrains. We detected several genetic&lt;br/&gt;&lt;br&gt; and phenotypic differences, suggesting that one of the substrains had been&lt;br/&gt;&lt;br&gt; genetically contaminated from another rat strain. The second study is based on the&lt;br/&gt;&lt;br&gt; observation that a spontaneous mutation in our DA rat colony results in decreased&lt;br/&gt;&lt;br&gt; arthritis susceptibility in the DA rats. We subsequently isolated the mutation in a&lt;br/&gt;&lt;br&gt; new substrain of DA rats, called DACP, and using genetic linkage analysis we located&lt;br/&gt;&lt;br&gt; the mutation and identified a new quantitative trait locus (QTL) for pristaneinduced&lt;br/&gt;&lt;br&gt; arthritis (PIA) at chromosome 9, Pia27. In the second part of this thesis, we&lt;br/&gt;&lt;br&gt; were utilizing the traditional congenic rat strain strategy in the identification and&lt;br/&gt;&lt;br&gt; characterization of arthritis regulating loci. The third paper investigated the influence&lt;br/&gt;&lt;br&gt; of different genetic backgrounds on the detection of previously reported loci for PIA.&lt;br/&gt;&lt;br&gt; We found that the arthritis-regulating gene Ncf1 as well as the major histocompatibility&lt;br/&gt;&lt;br&gt; complex (MHC) are silent in certain genetic backgrounds, while they&lt;br/&gt;&lt;br&gt; can be detected in other genetic setups. The fourth study describes the positional&lt;br/&gt;&lt;br&gt; cloning of the immunoglobulin lambda light chain (Igl) locus as one locus controlling&lt;br/&gt;&lt;br&gt; rheumatoid factor (RF) production in rats. In addition, evidence suggests that this&lt;br/&gt;&lt;br&gt; genetic region may be associated with Ovalbumin-induced airway inflammation, an&lt;br/&gt;&lt;br&gt; animal model for allergic bronchitis or asthma.&lt;br/&gt;&lt;br&gt; Identification of genes involved in complex disorders such as RA will be extremely&lt;br/&gt;&lt;br&gt; valuable in understanding disease regulating mechanisms as well as improve diagnosis&lt;br/&gt;&lt;br&gt; and identification of specific targets for therapeutic drugs. However, the findings in&lt;br/&gt;&lt;br&gt; this thesis demonstrate that mapping those genes is a complex and challenging&lt;br/&gt;&lt;br&gt; process and involving various problems, such as genetic variability and complex&lt;br/&gt;&lt;br&gt; genetic interactions.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d2b35308-95bd-4183-b984-d74abb065049</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis_Carola_Rintisch.pdf">https://portal.research.lu.se/files/3136945/1278092.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">6319299</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Pristane-induced arthritis</topic> <topic>Rat strain</topic> <topic>Autoimmunity</topic> <topic>Rheumatoid arthritis</topic> <topic>Quantitative trait locus</topic> </subject> <subject authority="lup"> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-99-6</identifier> <identifier type="oldLupId">1277671</identifier> <part> <detail type="volume"> <number>2009:12</number> </detail> <extent unit="pages"> <total>40</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-02-13T13:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Hematopoietic stem cells (HSCs) supply and maintain this system by differentiating via intermediates into lineage-restricted progenitors that strongly proliferate to keep up with the high turn-over of mature blood cells. In AML, the mechanisms controlling differentiation and proliferation of myeloid cells are disturbed leading to the accumulation of undifferentiated cells that interfere with the production of normal blood cells. &lt;br/&gt;&lt;br&gt; Mutations of the transcription factor C/EBPα have been observed in 10 percent in AML with normal cytogenetics. In addition, internal tandem duplications (ITD) of FLT3 are frequently observed alterations in AML and coincide with mutations of C/EBPα. &lt;br/&gt;&lt;br&gt; The effects of FLT3-ITD cooperation with C/EBPα mutations in AML are not fully understood. To address this, knockin mouse strains harboring different Cebpa mutations and Flt3-ITD were used to generate an AML mouse model. This model demonstrated a block at the transition from pGMP to GMP due to disrupted C/EBPα function. The cooperative effect of FLT3-ITD is composed of enhancing the generation of leukemia-initiating GMPs and activation of STAT5 targets. In in vitro studies it was demonstrated that FLT3-ITD reduces the cytokine-requirements for cell growth and that leukemic cells harboring FLT3-ITD are more sensitive to inhibition of the FLT3 pathway in vitro. To address the impact of FLT3-ITD gene dosage and loss of Flt3 wild type allele in vivo the Flt3-ITD knockin mouse was crossed to the Flt3 receptor knockout mouse. These studies demonstrated that the myeloproliferative phenotype was FLT3-ITD dosage-dependent and independent of FL. In summary, the data presented provide deeper insights into oncogene cooperation and FLT3-ITD dosage in AML.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Leukemi är en cancersjukdom i blod och benmärg som karakteriseras av en störd blodbildning. Vid normal blodbildning delar sig ett begränsat antal omogna blodceller så kallade blod stamceller (eller hematopoietiska stamceller) och mognar till funktionella blodceller. Genom att dela sig utan att mogna har stamcellerna även potential till at förnya sig själva. När nya stamceller och mogna celler samtidigt bildas kan en kontinuerlig blodproduktion upprätthållas genom livstiden. Då leukemi uppstår mognar blodcellerna inte fullt ut, vilket leder till en anhopning av omogna celler med brist av funktionella blodceller som följd. Ett fåtal leukemiska stamceller tros ligga bakom den maligna expansionen. Konventionell leukemibehandling minskar mängden omogna celler men förefaller inte vara verksam på de leukemiska stamcellerna. De leukemiska stamceller som blir kvar efter behandling förmodas vara den bakomliggande orsaken till återfall. Akut myeloisk leukemi (AML) är en typ av leukemi där man känner till flera genetiska förandringar (mutationer) som förekommer i de maligna blodcellerna. För att bättre kunna forstå uppkomst av AML har vi upprättat en musmodell för human AML genom att föra in tre vanligt förekommande mutationer i det genetiska materialet hos musens blodceller. Vår modell tillåter molekylära och cellulära studier både före och under manifestationen av sjukdomen. Jämfört med tidigare modeller representerar vår modell orsaken till leukemien på ett bättre sätt. &lt;br/&gt;&lt;br&gt; Våra resultat och de framtida studier de kommer att leda till kan bidra till nya framtida terapier i kampen mot AML. Dessutom kan musmodellen användas för att studera innovativa och oprövade läkemedel.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/33d32ebd-082c-424e-8725-19e3f0c6a4b7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kristian_final_2.pdf">https://portal.research.lu.se/files/3137144/2440752.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1629031</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Molecular Medicine and Gene Therapy, Dept of Laboratory Medicine</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Hematopoiesis</topic> <topic>Hematopoietic Stem Cell</topic> <topic>AML</topic> <topic>FLT3</topic> <topic>C/EBPalpha</topic> </subject> <subject authority="lup"> <topic>Hematology</topic> <topic>Medical and Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-99-4</identifier> <identifier type="oldLupId">2438633</identifier> <part> <detail type="volume"> <number>2012:37</number> </detail> <extent unit="pages"> <total>100</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-05-03T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>33d32ebd-082c-424e-8725-19e3f0c6a4b7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:03:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:03:38+02:00</recordDateApproved> </recordInfo> </mods>

The work rehabilitation in focus was the Redesigning Daily Occupations (ReDO) programme. This is a new work rehabilitation programme for women on sick leave due to stress-related disorders, which was implemented in the primary health care services. The instruments developed and evaluated were the Worker Role Self-assessment (WRS) and the Work Environment Impact Scale – Self Rating (WEIS-SR). The WRS was evaluated in pain rehabilitation clinics (Study I), while the WEIS-SR was investigated in primary health care (Study II). Both instruments showed good psychometric properties, but further development and evaluations are needed. The WEIS-SR was then used in the ReDO programme in order to investigate whether the women’s perceptions of their work environment had changed after completed rehabilitation or at follow-ups 6 and 12 months after, as compared to their initial ratings (Study III). The result showed that the women rated their work environment as better after having completed the programme and at the follow-ups. In Study IV some women in the ReDO programme were interviewed regarding their perceptions and experiences from participating in the ReDO. The analyses of the interviews showed that the women were satisfied and thought the programme had suited their needs for rehabilitation. They highlighted a process of self-analysis that resulted in person-related changes and described the importance of the support they had received during the process and during their return to work. This thesis has contributed to the development of instruments and a qualitative evaluation of the ReDO based on the clients’ perspectives.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Denna avhandling har fokus på arbetsrehabilitering för personer som är sjukskrivna eller riskerar att bli det. &lt;br/&gt;&lt;br&gt; För dem som blir sjukskrivna kan det bli aktuellt med arbetsrehabilitering. Första steget i en sådan är att utreda individens arbetsförmåga. Utredningen ligger sedan till grund för val av fortsatta åtgärder, för utvärdering av rehabiliteringen samt i vissa fall också för beslut om ersättning från socialförsäkringen. För att utredningen ska ge ett pålitligt resultat behöver bedömningsmetoder och instrument vara valida och reliabla. De interventioner som sedan väljs ska vara evidensbaserade. Vad gäller åtgärder för individer med stress-relaterade sjukdomstillstånd finns det ännu inte så mycket evidens. &lt;br/&gt;&lt;br&gt; Vardagsrevidering är ett arbetsrehabiliteringsprogram som visats vara framgångrikt så tillvida att en utvärdering visade att deltagarna i interventionsgruppen återgick i arbete i större utsträckning än en jämförelsegrupp. Programmet vänder sig till kvinnor som är sjukskrivna på grund av stressrelaterade tillstånd och fokuserar inte bara på arbete utan också dygnets övriga aktiviteter. Vardagsrevidering består av en 10 veckors teoretisk del och därefter 6 veckors praktik på deltagarens ordinarie arbetsplats. Syftet med den teoretiska delen är att deltagarna ska få insikt i vad de gör och hur de utför sina aktiviteter under dygnet, samt hur de upplever detta. Utifrån denna analys kan de sedan formulera sina egna mål för att förändra vardagen och hitta strategier för att nå målen. Vardagsrevidering genomfördes och utvärderades som en forskningsstudie i primärvården i södra Sverige.&lt;br/&gt;&lt;br&gt; Nya metoder för bedömning och rehabilitering behöver utvecklas i takt med att förändringar sker i samhället och ny kunskap erhålls. De nya metoderna behöver sedan utvärderas vetenskapligt. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De olika delstudierna&lt;br/&gt;&lt;br&gt; Det övergripande syftet med avhandlingen var att bidra till utvecklingen av nya bedömningsinstrument för användning i arbetsrehabilitering, samt att belysa klienters upplevelse av att delta i ett arbetsrehabiliteringsprogram för kvinnor med stressrelaterade besvär. &lt;br/&gt;&lt;br&gt; Studie 1 syftade till att utveckla och utvärdera ett instrument för att undersöka klientens syn på sin arbetsroll. Instrumentet ”Worker Role Self-assessment” (WRS) är en självskattningsversion av den svenska versionen av intervjuinstrumentet Worker Role Interview, som i sin tur är grundat på Model of Human Occupation (MOHO). I WRS får klienten skatta hur han/hon ser på sin arbetsroll och faktorer som påverkar denna, på en fyrgradig ordinalskala. I studien utvärderades innehållsvaliditet och användbarhet med ett frågeformulär som besvarades av fyra arbetsterapeuter och 23 klienter på smärtrehabiliteringskliniker i södra Sverige. Test-retest reliabilitet och intern konsistens undersöktes på basis av klienternas ifyllda WRS. En annan grupp, som bestod av 83 klienter som genomgick ett program för arbetsrehabilitering vid en annan smärtrehabiliteringsklinik, fyllde i WRS före och efter programmet. Även här undersöktes instrumentets interna konsistens, men också dess känslighet för förändring och dess prediktiva validitet för arbetsförmåga. Analyserna visade att WRS hade god innehållsvaliditet och användbarhet, och test-retest reliabiliteten var god eller moderat för de flesta frågorna. Instrumentets interna konsistens var acceptabel. Klienternas initiala skattning av en av frågorna var relaterad till arbetsförmåga efter arbetsrehabiliteringsprogrammet. Samma fråga visade sig vara känslig för förändring och skattningarna var signifikant lägre efter rehabiliteringen. Dock visade det sig finnas en takeffekt i skattningarna, vilket påverkar känsligheten för förändring. Studiens resultat visade att instrumentets frågor behöver ses över och att fortsatta utvärderingar av instrumentets psykometriska egenskaper behöver göras.&lt;br/&gt;&lt;br&gt; I studie 2 utvecklades och utvärderades ett annat självskattningsinstrument, Work Environment Impact Scale – Self Rating (WEIS-SR), som är en självskattningsversion av det svenska intervjuinstrumentet WEIS, även detta grundat på MOHO. Med hjälp av WEIS-SR skattar klienten sin arbetsmiljö och faktorer som är relaterade till arbetsmiljön. WEIS-SR utvärderades i två steg, båda i primärvården i södra Sverige. Klienterna led av stressrelaterade besvär och/eller besvär i rörelseorganen. WEIS-SR består av 15 frågor som skattades på en fyrgradig ordinalskala i steg ett. Innehållsvaliditet, användbarhet, samt intern konsistens undersöktes i steg ett. För att undersöka innehållsvaliditet och användbarhet fylldes ett frågeformulär i av tio arbetsterapeuter och 44 klienter. Resultatet visade att WEIS-SR hade god innehållsvaliditet och användbarhet, samt att den interna konsistensen var bra. Dock identifierades en takeffekt, vilket ledde till att svarsskalan inför steg två ändrades till att omfatta fem alternativ. Steg två genomfördes i samband med en sexmånadersuppföljning av de klienter som genomgått Vardagsrevidering. Tjugosex klienter fyllde i WEIS-SR vid två tillfällen. Här studerades test-retest reliabilitet och intern konsistens. Den interna konsistensen var god även för den reviderade versionen och test-retest reliabiliteten var god till moderat för de flesta av frågorna. Studien visade att WEIS-SR hade goda förutsättningar för klinisk användning, men att fortsatta utvärderingar av dess psykometriska egenskaper behöver göras. &lt;br/&gt;&lt;br&gt; Syftet i studie 3 var att undersöka hur deltagarna i Vardagsrevidering skattade sin arbetsmiljö då de började programmet och om skattningarna förändrades under eller efter programmet, samt om det fanns något samband mellan de initiala skattningarna och arbetsåtergång vid en 12-månadersuppföljning. Den reviderade versionen av WEIS-SR (med femgradig skala) användes och fylldes i av de 42 deltagarna i Vardagsrevidering vid fyra tillfällen: före och efter programmet, samt vid uppföljningar efter 6 och 12 månader. Eventuella relationer mellan deltagarnas initiala WEIS-SR skattningar och arbetsåtergång vid 12-månadersuppföljningen undersöktes. Resultatet visade att deltagarna värderade sin arbetsmiljö ganska högt vid start av Vardagsrevidering, men att skattningarna var signifikant högre efter programmet och vid uppföljningstillfällena. Dock kunde inget samband mellan deras initiala skattningar och arbetsåtergång vid uppföljningen påvisas.&lt;br/&gt;&lt;br&gt; Studie 4 syftade till att undersöka hur några deltagare upplevde att genomgå Vardagsrevidering. Sju av deltagarna intervjuades under tiden för Vardagsrevidering samt i samband med att den avslutades. Deltagarna var mycket nöjda och tyckte att programmet hade passat deras behov av rehabilitering. De framhöll särskilt självanalysen som enligt deras mening hade lett fram till förändringar i hur de hanterade sina dagliga aktiviteter. Förändringarna hade skett gradvis och de kände att de hade fått det stöd de behövde i sin förändringsprocess. De var också nöjda med att ha fått prova att arbeta under arbetspraktiken. Då de avslutade Vardagsrevidering kände de flesta att de skulle klara att arbeta/studera och ha en hållbar vardagssituation framöver. Studien har bidragit till en förståelse för hur Vardagsrevidering kan uppfattas ur ett deltagarperspektiv. &lt;br/&gt;&lt;br&gt; Samtliga delstudier har fokuserat på klienten och hans/hennes upplevelser, vilket är en viktig del i arbetsrehabilitering. Delstudierna har haft ett arbetsterapeutiskt perspektiv och haft fokus på klienters upplevelser av sitt aktivitetsutförande och förutsättningar för detta. Avhandlingen får anses ha bidragit till utvecklingen av nya bedömningsinstrument och den visade att deltagarnas såg mera positivt på sin arbetsmiljö under och efter ett arbetsterapeutiskt arbetsrehabiliteringsprogram. Avhandlingen visade också att deltagarna i arbetsrehabiliteringsprogrammet var mycket nöjda med programmet och det stöd de fått, samt att de upplevde att de med hjälp av programmet kunnat förändra sitt sätt att hantera sina dagliga aktiviteter. Detta ger stöd åt arbetsterapeuternas arbetssätt: att utgå från klientens upplevelser och sedan stödja dem i att förändra sin egen aktivitetssituation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ba2eea18-61b3-43d0-8068-e79d14affc4b</url> </location> </relatedItem> <originInfo> <publisher>Division of Occupational Therapy and Gerontology</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Work</topic> <topic>assessment</topic> <topic>daily activities</topic> <topic>client’s perception</topic> <topic>evaluation</topic> </subject> <subject authority="lup"> <topic>Occupational Therapy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-88-4</identifier> <identifier type="oldLupId">1897648</identifier> <part> <detail type="volume"> <number>2011:40</number> </detail> <extent unit="pages"> <total>152</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-05-12T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The presenting clinical picture results from a mixture of direct toxic actions by the microbiological agent and of the immune response mounted by the host. There is often a rapid onset, which may constitute a diagnostic and therapeutic challenge, whereas in other cases an extensive investigation over a long time period can fail to identify a causal microbial agent. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The aim with this thesis was to study the cellular immune response with phenotypical assays, in patients with severe infections with focus on sepsis. We assessed if our findings could serve as biomarkers and provide valuable diagnostic and possible also therapeutic information. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the first part (paper I) we examined surface markers on white blood cells from patients with severe infections. In some instances our analysis could differentiate between infections of bacterial and viral origin. In the second part (paper II-IV) we examined the incidence and nature of the immune alterations found in patients with sepsis and septic shock. We identified a protein (Wnt5a) that inhibited differentiation of monocytes to monocyte-derived myeloid dendritic cells (Mo-mDC), which may play a role in the DC depletion often seen in sepsis. Also, as indicated by cell surface phenotype, a large inter-individual variation of immune activation and immunosuppression was detected in patients with sepsis, with a dominance of immunosuppression in patients with septic shock. Finally, different types of immature myeloid immunosuppressive cells, myeloid-derived suppressor cells (MDSCs) were found in patients with sepsis; Mo-MDSCs were preferentially expanded in patients with gram-negative sepsis, whereas granulocytic MDSCs (PMN-MDSCs) accumulated in patients with gram-positive sepsis. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We conclude that the immune response during severe infections shows large inter-individual variations and biomarker guided therapy could be useful in individualised treatment.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Det är en utmaning att behandla patienter med allvarliga infektioner eftersom immunförsvaret reagerar olika på olika mikroorganismer. Immunförsvarets reaktion har i sin tur en stor betydelse för symtombild, kliniska fynd och prognos. Vid blodförgiftning (sepsis) förändras dessutom sannolikt immunsvaret under det kliniska förloppet. Man tror att det inledningsvis vid sepsis sker en aktivering av det proinflammatoriska immunförsvaret. I de fall där aktiveringen blir för kraftig skapas en förödande antiinflammatorisk negativ återkoppling med risk för sekundära infektioner och död.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den här avhandlingens mål var att undersöka om en utökad analys av vita blodkroppar kan ge information av värde för diagnostik och behandling av patienter med allvarliga infektioner med fokus på sepsis.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I den första studien granskade vi ytmarkörer på vita blodkroppar från patienter med antingen sepsis, borrelia, tuberkulos, körtelfeber, influensa eller bindvävssjukdom. Vi kunde där se att vissa markörer framträdde vid en halvakut bakteriell infektion eller en bindvävssjukdom. Den här typen av analys skulle kanske i en del fall kunna hjälpa till att skilja mellan bakterie- och virusinfektioner. Vår slutsats är att metoden skulle kunna hjälpa till i diagnostiken av vissa patienter med oklar feber.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den andra artikeln var en studie av dendritiska celler som, genom att de presenterar antigener för lymfocyter, fungerar som en viktig brygga mellan det medfödda och det förvärvade immunförsvaret. Vi kunde visa att det specifika proteinet Wnt5a hämmade bildandet av speciella dendritiska celler med ursprung från monocyter. Vi kunde också visa att när monocyter stimulerades med Wnt5a började de tillverka IL-6. Wnt5a’s egenskaper skulle kunna vara en av förklaringarna till det minskade antalet dendritiska celler hos patienter med sepsis.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I vår tredje artikel undersökte vi det aktiverande och det hämmande immunsvaret hos patienter med sepsis, septisk chock och allvarliga virusinfektioner. Vi såg att tecken på immunhämning dominerade hos patienter med grampositiv sepsis och septisk chock medan monocytaktivering var vanligt hos patienter med gramnegativ sepsis. Det viktigaste fyndet var dock de uttalade individuella variationerna. Våra data antyder att det är viktigt att undersöka hur immunförsvaret reagerat hos den enskilde sepsis patienten innan man ger behandling för att undertrycka eller stimulera det.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I vårt fjärde arbete undersökte vi förekomsten och funktionen av en särskild sorts immunhämmande celler, myeloid derived suppressor cells (MDSCs), hos patienter med sepsis. MDSCs är en nyupptäckt celltyp känd för att dämpa immunförsvaret vid cancer. I studien såg vi att olika bakterier kan framkalla generering av olika typer av MDSCs. Vi såg också att MDSCs kan hämma tillväxten av T-celler.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/95e313bf-9b12-43d3-9a8b-2806710affa1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Janols_avhandling_slutgiltlig_version.pdf">https://portal.research.lu.se/files/3138289/4419335.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">10430242</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>immunosuppression</topic> <topic>myeloid-derived suppressor cells</topic> <topic>T cells</topic> <topic>dendritic cells</topic> <topic>monocytes</topic> <topic>sepsis</topic> <topic>Biomarkers</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-76-2</identifier> <identifier type="oldLupId">4406483</identifier> <part> <detail type="volume"> <number>2014:50</number> </detail> <extent unit="pages"> <total>166</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-05-16T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>95e313bf-9b12-43d3-9a8b-2806710affa1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:03:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:03:53+02:00</recordDateApproved> </recordInfo> </mods>

On one hand, increased pressure/stretch for a prolonged time can cause structural changes in vessel wall; on&lt;br/&gt;&lt;br&gt; the other hand, lack of pressure/stretch can promote a phenotype shift. This thesis investigates novel roles of&lt;br/&gt;&lt;br&gt; microRNAs and protein tyrosine kinase 2 in pressure/stretch-induced signaling mechanisms in the vascular wall.&lt;br/&gt;&lt;br&gt; Using two different knockout mouse models, we uncovered a novel role of microRNAs in the pressure-induced&lt;br/&gt;&lt;br&gt; myogenic response. We demonstrated that global deletion of smooth muscle-specific microRNAs causes a loss of&lt;br/&gt;&lt;br&gt; pressure-induced contraction and that this likely involves diminished calcium influx due to reduced stretch-induced&lt;br/&gt;&lt;br&gt; activation of the PI3K/Akt pathway. Similarly, global deletion of the smooth muscle enriched miRNA-143/145 also&lt;br/&gt;&lt;br&gt; depleted myogenic responses but this effect could be due to several combined factors including loss of calcium influx&lt;br/&gt;&lt;br&gt; and decreased expression of myosin light chain kinase. Furthermore portal veins of miRNA-143/145 KO mice exhibit&lt;br/&gt;&lt;br&gt; lack of stretch-induced contractile differentiation, which may in part be due to a reduced expression of L-type calcium&lt;br/&gt;&lt;br&gt; channels caused by an increased expression of the transcriptional repressor DREAM. Using a novel small molecule&lt;br/&gt;&lt;br&gt; inhibitor of PYK2, we demonstrated that PYK2 could distinguish between non-voltage and voltage-dependent calcium&lt;br/&gt;&lt;br&gt; pools to initiate signal transduction in the smooth muscle of portal vein. Inhibition of PYK2 can reduce phenotype&lt;br/&gt;&lt;br&gt; modulation and apoptosis in balloon injured carotid arteries.&lt;br/&gt;&lt;br&gt; In conclusion, we have established an indispensable role of microRNAs in the presssure-induced myogenic response&lt;br/&gt;&lt;br&gt; and maintainance of stretch-induced conctractile differentiation. Morover we have established that PYK2 is involved in&lt;br/&gt;&lt;br&gt; stretch-induced calcium handling in spontaneously active portal vein and in phenotypic shift of smooth muscle cells&lt;br/&gt;&lt;br&gt; following vascular injury.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/bbf5cca6-b2f1-47c1-9f02-e261d619ce51</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Anirban_BhattchariyaKappa.pdf">https://portal.research.lu.se/files/3142893/4645263.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">24937925</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Vascular Physiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>portal vein</topic> <topic>resistance artery</topic> <topic>myogenic tone</topic> <topic>PYK2</topic> <topic>calcium</topic> <topic>microRNA</topic> </subject> <subject authority="lup"> <topic>Physiology and Anatomy</topic> <topic>Basic Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-030-2</identifier> <identifier type="oldLupId">4619000</identifier> <part> <detail type="volume"> <number>2014:101</number> </detail> <extent unit="pages"> <total>89</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-09-26T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>bbf5cca6-b2f1-47c1-9f02-e261d619ce51</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:10+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:10+02:00</recordDateApproved> </recordInfo> </mods>

We have demonstrated an increased expression of cerebrovascular contractile receptors in the brain. This is hypothesized to mitigate cerebral blood flow and exacerbate tissue damage after stroke. An increased contractile property of these receptors has been demonstrated to occur by MEK/ERK1/2 signaling. The majority of pre-clinical studies on stroke are performed in young healthy male animals, despite the fact there is a difference in male and female stroke incidence. The present thesis therefore aimed to investigate the status of vascular receptor changes after experimental stroke and organ culture, with two focus areas that previously have been missing – studies on human material and female subjects. In human cerebral arteries, we found that increased vasoconstriction of 5-HT1B, AT1 and ETB receptors during organ culture, a model of ischemic-like receptor changes, is mediated by B-Raf/MEK/ERK1/2 signaling. Although, increased mRNA and protein of these receptors were found in arteries from both sexes, the contraction to Ang II and ET-1 was markedly lower in female arteries. Focal cerebral ischemia in female rats induced an enhanced contractile property of cerebrovascular ETB receptors, similar to previous observations in males. Ovariectomy, and thereby loss of progesterone and estrogen, resulted in less ischemia-induced ETB receptor upregulation. Hormone therapy with progesterone, but not estrogen, reversed these changes. The increased ETB receptor expression and vasoconstriction after cerebral ischemia in female rat was demonstrated to be mediated by MEK/ERK1/2 signaling. MEK1/2 inhibition attenuated the ETB receptor upregulation and improved the neurological outcome. The present thesis demonstrates for the first time sex differences in vascular function of human cerebral arteries. The underlying mechanism in decreased responsiveness of female arteries remains to be elucidated. This may involve differences in receptor coupling or signal transduction influenced by female sex steroid hormones, or biological sex. Our experimental studies on stroke suggest the loss of progesterone after ovariectomy suppresses ischemia-induced ETB receptor upregulation. Further, the signal transduction pathway involved in vascular receptor changes after cerebral ischemia is suggested to be similar in both sexes. MEK1/2 inhibition is therefore a promising therapeutic target for stroke therapy in both males and females.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2ca47738-655b-49b6-8b4d-b8ba213c5574</url> </location> </relatedItem> <originInfo> <publisher>Medicine (Lund)</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>endothelin receptors</topic> <topic>Cerebral ischemia</topic> <topic>sex</topic> <topic>estrogen</topic> <topic>progesterone</topic> <topic>sex differences</topic> <topic>human cerebral arteries</topic> <topic>endothelin-1</topic> <topic>angiotensin II</topic> <topic>middle cerebral artery occlusion</topic> <topic>extra-cellular signal regulated kinase 1 and 2</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-85-2</identifier> <identifier type="oldLupId">3362991</identifier> <part> <detail type="volume"> <number>2013:16</number> </detail> <extent unit="pages"> <total>138</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.biomedcentral.com/1471-2202/12/5</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://onlinelibrary.wiley.com/doi/10.1111/j.1748-1716.2011.02392.x/abstract</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-03-01T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>2ca47738-655b-49b6-8b4d-b8ba213c5574</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:11+02:00</recordDateApproved> </recordInfo> </mods>

The difficulty hierin lies in the the lack of any clear understanding or agreement for what the term implies for retailers and how to implement it in retailers’ daily operations. Instead, retailers need to handle a number of different – at times competing – understandings of SCP among their stakeholders and combine these into a strategy that fits their business interests. In this thesis, I study the interaction between retailers, their stakeholders and market demand to understand how the complexity of the sustainability discourse is translated into concrete action on the shop floor. My results show retailers to be highly flexible in their work with SCP, however also quite unstrategic. Much of retailers’ efforts to integrate SCP into their operations is based on a trial-and-error process with frequent mistakes and change of direction. To approach SCP more strategically more attention must be paid to the sensemaking process of SCP among stakeholders and how it connects to market demand. My research found that rather than focusing on the overall sustainability of products and services, retailers ought to comparmentalize SCP to match specific stakeholder groups in a meaningful way. Retail brands have emerged as particularly useful tool in this respect. Due to the property rights assigned to such brands, they offer the retailer the ability to actively enage with SCP and adapt its meaning to stakeholder expectations. However, sensemaking of SCP is also to a great extent a local process, removed from the national discourse. While brands are well-suited to engage with the macro-discourse, they are not sufficiently able to adapt to the micro-level discourse. My research points to the important role individual stores have in the adaptation process of SCP to the micro-level discourse. Several examples of successful micro-adaptation to local sensemaking of SCP at the store level could be observed in my research. Successful integration of SCP into a retailer’s operation therefore seems to depend on a functioning multi-layer process within the organisation, where both headquarters and stores contribute their strengthes to a functioning internal translation procees of SCP, from global discourse to local enaction. These results have particular relevance for centralized retail organisations. They imply more responsibility for stores in the sensemaking and operationalisation of SCP as a way to achieve a more contextually meaningful approach to SCP.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Retailers are increasingly expected to use their market power to support the societal goal of sustainable consumption and production (SCP). For retailers, the challenge herein lies in the difficulty to translate the abstract societal discourse into concrete action in the marketplace. This thesis argues that retailers are well advised to give more attention to the individual retail store as place of stakeholder engagement and customer communication. To integrate SCP into their operations, retailers must therefore aim to better understand and address context-specific sustainability concerns.&lt;br/&gt;&lt;br&gt; Sustainability is a disputed and poorly defined term and stakeholder concerns are manifold. Moreover these concerns are often only loosely connected to scientific evidence. Instead, stakeholder understanding of SCP is defined in social networks and through the societal norms stakeholders are exposed to. SCP therefore receives multiple meanings in the marketplace. Retailers are exposed to these different – and at times contradicting – understandings of sustainability. This makes it difficult for retailers to decide how to implement sustainability in their daily operations. For retailers to work with SCP therefore requires the ability to understand and adjust to this variation.&lt;br/&gt;&lt;br&gt; Retailers have the ability to influence stakeholders’ understanding of SCP. Through their market communication and their assortment decisions they influence how stakeholders make sense of SCP. Sustainable retailing is therefore the process of identifying relevant stakeholder demands, and translating them into market action that meets market demand and is beneficial to the retail organisation.&lt;br/&gt;&lt;br&gt; To study how retailers translate the sustainability discourse into market action, and how they could improve their work with SCP, this thesis builds on empirical work that included semi-structured interviews, observations, focus groups, the collection of grocery shopping receipts and the study of secondary literature such as corporate responsibility reports and reports from independent organisations.&lt;br/&gt;&lt;br&gt; The results show that retailers are highly pragmatic in response to the sustainability discourse. They have developed strategies to deal with the changeability of the sustainability discourse and the multiple meanings of sustainability. Their response is topic-dependent and executed in line with stakeholder expectations. How a retailer works with organic food, for example, can look very different from the retailer’s strategy to deal with climate change. Retailers neglect topics their stakeholders do not value. The way they translate SCP into market action is thus determined by their stakeholders’ concerns, beliefs and values.&lt;br/&gt;&lt;br&gt; A popular instrument for retailers to address various stakeholder concerns are retail brands. These brands have proliferated in recent years and indeed appear to support the integration of SCP in the food industry. Compared to independent 3rd party certification and labelling, retail brands offer the advantage of property rights for retailers. While 3rd party labels are non-exclusive, retail brands offer more incentive for retailers to invest into the development of one or several sustainability-oriented brands. Interestingly, such brands appear to mostly function in close cooperation with independent 3rd party certification and labelling. Retailers use such certification and labelling to increase trust and credibility in their own brands and to facilitate supply-chain management.&lt;br/&gt;&lt;br&gt; This thesis also highlights the important role of retail stores in the retailer’s work with SCP. Retail stores are embedded in the same socio-cultural context as local stakeholders. This embeddedness allows stores to better understand and follow the concerns and preferences regarding SCP in a local context. In my research, I found multiple examples of in-store adaptation to the local context, with innovative and successful outcome. These observations were most prominent in ICA stores. The decentralized organizational structure of the ICA organization enables more decision-making in the retail store. This freedom gives store managers and staff the ability to react to local concerns. However, despite clear indications that stores’ involvement in the implementation of SCP leads to positive outcomes, my research also shows that retailers are underexploiting this potential. Work with SCP is concentrated on the central level (headquarters), with stores at the receiving end of the translational process happening in the retail organisation. This is unfortunate, as it reduces the ability of retailers to create value for consumers and other stakeholders in SCP.&lt;br/&gt;&lt;br&gt; My research suggests that retailers will be more successful in implementing sustainable retailing where they give stores room to adapt to their local context. In cases where both a retailers’ headquarters and the store actively engage in the translation of the sustainability discourse into market action, this multi-layered process in which headquarters capture macro-influences, while stores embed sustainability into the micro-context, retailers are better able to find ways to translate the sustainability discourse into in-store action that matches the store-context and thus the localized understanding of sustainability.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; For retailers, these findings imply that rather than focusing on the overall sustainability of products and services, retailers should compartmentalize sustainability to match specific stakeholder groups in a meaningful way. Such a strategy enables variation and differentiation in sustainable retailing.&lt;br/&gt;&lt;br&gt; This thesis describes how retailers in Sweden and abroad already develop such a compartmentalisation and segmentation strategy, primarily through retail brands. These brands often combine various third party labels to develop a more market-oriented approach to SCP. It is likely that this trend will continue and continue to gain importance in retailers’ work with SCP. Importantly, third party labels will more and more occupy the role of support agents for the credibility and logistics behind retail brands, rather than to act as independent actors on the market. To better align the sustainability discourse with market demand, it is further important to give stores a greater role in the implementation of sustainable retailing. Stores are embedded in the same socio-cultural context as their customers and therefore well suited for the task of operationalizing sustainable consumption and production in the marketplace. More active stores are more likely to create the right ‘habitat’ for consumers to buy into SCP.&lt;br/&gt;&lt;br&gt; For policy-makers who would like retailers to take a more active part in SCP, the findings reported in this thesis imply that they must be careful not to over-regulate markets. The potential urge to introduce strict definitions of sustainable consumption and production and hold retailers accountable to them will potentially result in retailers only fulfilling the minimum requirements of the law as this might lead to a lack in incentives for retailers to innovate and actively develop the market and try to take advantage of the sustainability concerns among consumers. Policy-makers must be careful to regulate strictly based on scientific evidence and leave the translation of the scientific evidence into market action to market actors.&lt;br/&gt;&lt;br&gt; The same logic applies to research, which has too often aimed for a standardized understanding of SCP. A more flexible and fluid understanding of sustainability could enrich studies that try to capture SCP. Thereby a bias for one interpretation of SCP could be overcome, which might help to understand research topics such the ‘attitude-behaviour gap’ in SCP.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/799b5d62-5875-405f-bf80-9485f24add81</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Matthias_hela_avh_G5.pdf">https://portal.research.lu.se/files/3143352/5050310.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2981420</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>retail</topic> <topic>retail brands</topic> <topic>retail store</topic> <topic>sensemaking</topic> <topic>sustainable consumption</topic> </subject> <subject authority="lup"> <topic>Other Social Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>IIIEE Dissertations</title> </titleInfo> <identifier type="issn">1402-3016</identifier> <identifier type="isbn">978-91-87357-13-8</identifier> <identifier type="oldLupId">5050239</identifier> <part> <extent unit="pages"> <total>113</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-03-13T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>799b5d62-5875-405f-bf80-9485f24add81</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:14+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:14+02:00</recordDateApproved> </recordInfo> </mods>

The first question is whether examining segregation in terms of education is a fruitful tool for analyzing segregation in general. In answering that question, the dissertation describes how educational segregation relates to segregation by income, ethnicity and age. This first question is analyzed with the aid of the theoretical framework created by Pierre Bourdieu, especially in his work Distinction – A Social Critique of the Judgement of Taste. This dissertation concludes that education differs from other social variables in describing segregation and deserves to be analyzed on its own merits. &lt;br/&gt;&lt;br&gt; The second question is whether, how, and in what ways segregation relates to spatiality. In answering that question, the dissertation examines whether segregation is better described using spatial variables such as building age or ownership structure than through typo-morphological classification. This dissertation concludes that typo-morphological classification gives different starting points for analyzing segregation than other spatial variables. &lt;br/&gt;&lt;br&gt; This dissertation analyzes both questions through an empirical case study of the city of Malmö, using descriptive municipality statistics and geographical data (GIS). The data is then sorted into social variables (education, income, ethnicity, mobility,age, employment, political inclination) and spatial variables (property area, room units, centrality, building age, ownership relations). &lt;br/&gt;&lt;br&gt; This dissertation makes extensive use of the statistical methods linear regression analysis and correspondence diagrams in order to answer the questions.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c8ac9eaa-b134-49b5-b121-8dbd309f6a92</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Rickard-Persson-Segregation-Education-Space.pdf">https://portal.research.lu.se/files/3143525/1267388.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">16367235</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>typo-morphology</topic> <topic>comprehensive planning</topic> <topic>education</topic> <topic>segregation</topic> <topic>Bourdieu</topic> <topic>Malmö</topic> </subject> <subject authority="lup"> <topic>Civil Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Asplundbiblioteket</title> </titleInfo> <identifier type="issn">1404-1235</identifier> <identifier type="isbn">978-91-7740-092-9</identifier> <identifier type="oldLupId">1267386</identifier> <part> <extent unit="pages"> <total>318</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-19T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>c8ac9eaa-b134-49b5-b121-8dbd309f6a92</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:16+02:00</recordDateApproved> </recordInfo> </mods>

This thesis has focused on investigating the genetic contribution in obesity and insulin resistance by both candidate and global gene approaches with focus on the adipose tissue. In the first three studies, the adiponutrin gene and family were investigated. The family consisting of five genes (PNPLA1-5) are nutritionally regulated in the adipose tissue and the gene products show both lipogenic and lipolytic activity. The expression of adiponutrin (PNPLA3) was increased in the adipose tissue of obese subjects with higher expression in visceral adipose tissue compared to subcutaneous. Visceral expression correlated negatively with insulin resistance. In cultured adipocytes, insulin induced the PNPLA3 gene expression in a glucose dependent fashion while free fatty acids had no effect. Genetic variants in the PNPLA3 gene showed association with adult obesity, adipose tissue PNPLA3 mRNA expression, basal lipolysis, insulin secretion and sensitivity. Furthermore, genetic variance in PNPLA1 and PNPLA3, but not PNPLA2, PNPLA4 and PNPLA5, seem to be associated with juvenile obesity. The conclusion was that the PNPLA3 gene might be implicated in the pathogenesis of obesity, possibly via effects on insulin sensitivity. Out of the other members of the adiponutrin gene family only variants in the PNPLA1 gene seems to contribute to pathogenesis of childhood obesity. In the fourth study, the importance of including age, gender and level of physical activity in the analyses of genetic association with obesity was investigated with the Gly482Ser variant in the PPARGC1A gene as an example. Elderly males with low level of physical activity showed association between the 482Ser and obesity while there were no association in the whole population. The conclusion was that it is important to take age, gender and physical activity into account, when possible, when analysing genetic variance in relation to obesity. The last study focused on a global approach, investigating the total gene expression in adipose tissue after weight loss and weight stability trying to find genes that would predict a successful weight reduction. The approximately 100 genes showing concordant regulation after sustained weight loss might be of particular interest and may serve as adipostats, in other words, they might regulate adipose tissue homeostasis.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/440236af-8bcf-4330-a5ca-597656b7834e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Lovisa_J_HELA_A4.pdf">https://portal.research.lu.se/files/3143631/1241299.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1735229</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Insulin resistance</topic> <topic>Obesity</topic> <topic>Adipose tissue</topic> <topic>Adiponutrin</topic> <topic>PNPLA</topic> <topic>PPARGC1A</topic> <topic>Gene expression</topic> <topic>Case-control association study</topic> <topic>Microarray</topic> <topic>Genotyping</topic> <topic>Population-based study</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> <topic>Nutrition and Dietetics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-48-4</identifier> <identifier type="oldLupId">1241296</identifier> <part> <detail type="volume"> <number>2008:95</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-10T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>440236af-8bcf-4330-a5ca-597656b7834e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:17+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:17+02:00</recordDateApproved> </recordInfo> </mods>

An increased knowledge of prevalence,&lt;br/&gt;&lt;br&gt; contributing factors and impact on the individual’s life could enhance the possibility to&lt;br/&gt;&lt;br&gt; find more effective treatments and therefore more studies are needed. The overall aim&lt;br/&gt;&lt;br&gt; of this thesis was to evaluate PSSP with a special focus on prevalence, contributing&lt;br/&gt;&lt;br&gt; factors and consequences in daily life.&lt;br/&gt;&lt;br&gt; In an unselected stroke population of 327 individuals, the prevalence of PSSP was 22%&lt;br/&gt;&lt;br&gt; four months post stroke. Predictors of PSSP (paper I) were shown to be severely affected&lt;br/&gt;&lt;br&gt; arm motor function and severe impairments according to the National Institutes of&lt;br/&gt;&lt;br&gt; Health Stroke Scale, (NIHSS). About 70% of the individuals with impaired&lt;br/&gt;&lt;br&gt; sensorimotor function at stroke onset and PSSP at four months had still pain one year&lt;br/&gt;&lt;br&gt; later. Predictors for long-lasting PSSP were left-sided hemiparesis, pain frequency and&lt;br/&gt;&lt;br&gt; decreased passive shoulder abduction (paper II). In a group of 49 individuals with mild&lt;br/&gt;&lt;br&gt; to moderate sensorimotor impairments post stroke (24 with and 25 without PSSP) and&lt;br/&gt;&lt;br&gt; 11 healthy controls, somatosensory abnormalities were assessed with thermal and&lt;br/&gt;&lt;br&gt; mechanical thresholds using the Quantitative Sensory Testing (QST) method. No&lt;br/&gt;&lt;br&gt; significant difference in QST measurements were found between the groups with and&lt;br/&gt;&lt;br&gt; without PSSP, but both stroke groups had generally higher thermal thresholds and more&lt;br/&gt;&lt;br&gt; extreme low or high mechanical thresholds than the healthy controls (paper III). The&lt;br/&gt;&lt;br&gt; association between PSSP, sensorimotor function, ability to perform daily hand&lt;br/&gt;&lt;br&gt; activities, perceived participation and life satisfaction were evaluated in 24 individuals&lt;br/&gt;&lt;br&gt; with and 25 individuals without PSSP, all with mild to moderate sensorimotor&lt;br/&gt;&lt;br&gt; impairments. PSSP was associated with reduced motor function, but the PSSP had a&lt;br/&gt;&lt;br&gt; weak association with daily hand activities, perceived participation and life satisfaction&lt;br/&gt;&lt;br&gt; (paper IV). In conclusion, this thesis has shown that PSSP is common in individuals&lt;br/&gt;&lt;br&gt; with decreased upper extremity motor function. Left-sided hemiparesis, pain frequency&lt;br/&gt;&lt;br&gt; and decreased passive shoulder abduction seem to predict long-lasting PSSP. In&lt;br/&gt;&lt;br&gt; individuals with mild to moderate upper extremity paresis, somatosensory impairments&lt;br/&gt;&lt;br&gt; seem to have only a small impact on the pain and the PSSP appears to have a small&lt;br/&gt;&lt;br&gt; impact on their life situation.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Det övergripande syftet med denna avhandling var att öka kunskapen om skuldersmärta&lt;br/&gt;&lt;br&gt; efter stroke avseende förekomst, bidragande faktorer och konsekvenser i det dagliga&lt;br/&gt;&lt;br&gt; livet.&lt;br/&gt;&lt;br&gt; Stroke är i Sverige den vanligaste orsaken till funktionsnedsättning hos vuxna. Vanliga&lt;br/&gt;&lt;br&gt; funktionsnedsättningar vid insjuknandet är nedsatt rörelseförmåga i ena kroppshalvan,&lt;br/&gt;&lt;br&gt; känselnedsättning, balansstörning, synfältsbortfall och talsvårigheter. Smärta är vanligt&lt;br/&gt;&lt;br&gt; efter stroke och har uppgetts drabba mer än en tredjedel av personerna. Skuldersmärta&lt;br/&gt;&lt;br&gt; i den svaga sidan är en av de vanligaste typerna av smärta. Orakerna till skuldersmärta&lt;br/&gt;&lt;br&gt; efter stroke är fortfarande inte klarlagda, men anses vara multifaktoriella.&lt;br/&gt;&lt;br&gt; Skuldersmärtan kan inverka på det dagliga livet, men på vilket sätt är ofullständigt&lt;br/&gt;&lt;br&gt; kartlagt.&lt;br/&gt;&lt;br&gt; I delarbete I studerades förekomsten av skuldersmärta, liksom bidragande faktorer, i en&lt;br/&gt;&lt;br&gt; grupp bestående av 327 personer som insjuknat i stroke för första gången. Vid&lt;br/&gt;&lt;br&gt; uppföljning fyra månader efter insjuknandet, hade ca 20 % utvecklat skuldersmärta.&lt;br/&gt;&lt;br&gt; Skuldersmärtan debuterade vanligen inom några veckor eller någon månad efter&lt;br/&gt;&lt;br&gt; insjuknandet och hade samband med graden av rörelseförmåga i axeln och armen.&lt;br/&gt;&lt;br&gt; Vanligast var smärta i samband med rörelser och smärtan påverkade därför dagliga&lt;br/&gt;&lt;br&gt; aktiviteter såsom påklädning och förflyttning.&lt;br/&gt;&lt;br&gt; I delarbete II studerades vilka faktorer som bidrog till långvarig skuldersmärta. I studien&lt;br/&gt;&lt;br&gt; ingick 58 personer från den första studien, som alla hade nedsatt rörelseförmåga i ena&lt;br/&gt;&lt;br&gt; sidan vid insjuknandet och skuldersmärta fyra månader efter insjuknandet. Vid&lt;br/&gt;&lt;br&gt; uppföljning ett år senare hade 70% kvarstående smärta i skuldran. Faktorer associerade&lt;br/&gt;&lt;br&gt; med långvarig skuldersmärta var nedsatt rörelseförmåga i vänster kroppshalva, frekvent&lt;br/&gt;&lt;br&gt; smärta liksom nedsatt ledrörlighet i axeln.&lt;br/&gt;&lt;br&gt; I det tredje och fjärde delarbetet undersöktes 49 personer med stroke, 24 med och 25&lt;br/&gt;&lt;br&gt; utan skuldersmärta, och som hade lätt till måttlig nedsättning av rörelseförmågan i den&lt;br/&gt;&lt;br&gt; drabbade armen och handen. I det tredje delarbetet ingick dessutom 11 ålders- och&lt;br/&gt;&lt;br&gt; könsmatchade friska kontrollpersoner som inte hade någon skuldersmärta.&lt;br/&gt;&lt;br&gt; I delarbete III studerades om känselförändringar har betydelse för skuldersmärtan.&lt;br/&gt;&lt;br&gt; Quantitative Sensory Testing, QST, användes för att mäta trösklar för temperatur, tryck&lt;br/&gt;&lt;br&gt; och stick. Mätning av beröring och ledkänsel utfördes och personerna tillfrågades hur&lt;br/&gt;&lt;br&gt; de upplevde sin känsel. Resultaten visade ingen statistisk säkerställd skillnad mellan&lt;br/&gt;&lt;br&gt; personerna med och utan skuldersmärta gällande trösklar för temperatur, tryck och&lt;br/&gt;&lt;br&gt; stick. Däremot hade personerna som drabbats av stroke, både med och utan&lt;br/&gt;&lt;br&gt; skuldersmärta, högre trösklar för temperatur, dvs reagerade senare på stimuli än&lt;br/&gt;&lt;br&gt; kontrollgruppen. De hade också i större utsträckning extremt höga eller låga trösklar för&lt;br/&gt;&lt;br&gt; tryck- och stickstimuli jämfört med kontrollgruppen. Upplevelse av förändrad känsel&lt;br/&gt;&lt;br&gt; för kyla var vanligare i gruppen med skuldersmärta jämfört med gruppen utan&lt;br/&gt;&lt;br&gt; skuldersmärta.&lt;br/&gt;&lt;br&gt; I delarbete IV studerades hur skuldersmärtan efter stroke påverkar funktions- och&lt;br/&gt;&lt;br&gt; aktivitetsförmågan, upplevd delaktighet och livstillfredsställelse. Smärtkaraktäristika&lt;br/&gt;&lt;br&gt; registrerades och rörelseförmåga, ledrörlighet och känsel i armen bedömdes.&lt;br/&gt;&lt;br&gt; Undersökning av aktivitetsförmåga gjordes med ABILHAND, ett frågeformulär som&lt;br/&gt;&lt;br&gt; mäter självskattad förmåga att utföra vardagliga handaktiviteter. Upplevd delaktighet&lt;br/&gt;&lt;br&gt; skattades med Stroke Impact Scale och livstillfredsställelse med LiSat-11. Resultaten&lt;br/&gt;&lt;br&gt; visade att personerna som drabbats av skuldersmärta hade sämre rörelseförmåga och&lt;br/&gt;&lt;br&gt; ledrörlighet i armen än de som inte hade skuldersmärta. Däremot påverkade inte&lt;br/&gt;&lt;br&gt; skuldersmärtan förmågan att utföra vardagliga handaktiviteter, upplevd delaktighet eller&lt;br/&gt;&lt;br&gt; livstillfredsställelse.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar studierna i denna avhandling att skuldersmärta efter stroke är&lt;br/&gt;&lt;br&gt; vanligt bland personer som har nedsatt rörelseförmåga i armen. Vänstersidig svaghet,&lt;br/&gt;&lt;br&gt; frekvent smärta och nedsatt ledrörlighet i axeln fyra månader efter insjuknandet är&lt;br/&gt;&lt;br&gt; faktorer associerade med långvarig skuldersmärta. Förändrad känsel efter stroke tycks&lt;br/&gt;&lt;br&gt; endast ha en liten inverkan på skuldersmärtan hos personer med lätt till måttlig&lt;br/&gt;&lt;br&gt; nedsättning av rörelseförmågan i armen. Skuldersmärtan hos dessa personer tycks inte&lt;br/&gt;&lt;br&gt; begränsa det dagliga livet i någon större utsträckning, möjligen på grund av en&lt;br/&gt;&lt;br&gt; anpassning till att inte använda armen i situationer där smärtan förekommer. Resultaten&lt;br/&gt;&lt;br&gt; i avhandlingen kan leda till en bättre förståelse för hur vanligt skuldersmärta efter stroke&lt;br/&gt;&lt;br&gt; är. Genom att bidragande faktorer beskrivits kan personer med risk att drabbas av&lt;br/&gt;&lt;br&gt; skuldersmärta lättare identifieras och omhändertagandet förbättras.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a22c0bcf-d92b-4f5f-8962-29ba0eb78715</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa_ingrid_lindgren_till_lub_131112.pdf">https://portal.research.lu.se/files/3144224/4146891.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">763989</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Rehabilitation medicine, Lund university</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>sensory thresholds</topic> <topic>range of motion</topic> <topic>arm motor function</topic> <topic>outcome</topic> <topic>Stroke</topic> <topic>shoulder pain</topic> <topic>life satisfaction</topic> <topic>participation</topic> <topic>activities of daily living</topic> </subject> <subject authority="lup"> <topic>Other Medical and Health Sciences not elsewhere specified</topic> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-01-4</identifier> <identifier type="oldLupId">4146820</identifier> <part> <detail type="volume"> <number>2013:126</number> </detail> <extent unit="pages"> <total>62</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-12-06T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>a22c0bcf-d92b-4f5f-8962-29ba0eb78715</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:22+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:22+02:00</recordDateApproved> </recordInfo> </mods>

They develop as a result of dopamine loss in the striatum, subsequent to the progressive neurodegeneration of dopamin- ergic neurons in the substantia nigra. However, non-motor symptoms are frequent in PD patients and can greatly affect their quality of life. Among these, cognitive impairment affects primarily executive functions, as well as memory and attention. The diagnosis of dementia is made when the cognitive decline has progressed to a stage where the activities of daily living are severely affected. Although Lewy bodies containing alpha-synuclein may be a key neuropathological feature of dementia in Parkinson’s disease, the exact neurochemical deficits responsible for the development of cognitive decline are less clear. In fact, studies have shown separately that the dopaminergic and cholinergic systems can be affected in cognitively impaired and demented PD patients. The aim of this thesis was to investigate how the dopaminergic and cholinergic deficits contribute to the emergence of cognitive impairment in PD. To this end, detailed histological and stereological analyses of both neuronal populations were performed on postmortem brains from PD patients with and without dementia and suggested that concomitant degeneration of a subpopula- tion of non-nigral midbrain dopaminergic and basal forebrain cholinergic neurons could be an important factor in the development of dementia in PD. This study also demonstrated that the Lewy pathology was more severe in the basal forebrain and hippocampus in demented individuals compared with non-demented patients. To further elucidate the involvement of these particular deficits in dementia, we then attempted to model cognitive dysfunction in rats via targeted alpha-synuclein overexpression in the ventral tegmental area and the medial septum/vertical limb of the diagonal band of Broca, two structures rich in dopaminergic and cholinergic neurons, respectively. The animals displayed a unique impairment in spatial learning and memory, as assessed by the Morris water maze. The behavioral impairment appeared to be mediated by the alpha-synuclein pathology in the surviving neurons, thus suggesting a possible cellular dysfunction. Finally, this thesis describes a novel method to monitor the activity of choline acetyltransferase, the enzyme mediating acetylcholine synthesis, based on magnetic resonance spectroscopy. Future develop- ment of this method for in vivo applications could help discern the nature and the role of the cholinergic dysfunction in PD more precisely.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ab035615-de98-4559-9615-33d9d9e4ac39</url> </location> </relatedItem> <originInfo> <publisher>Brain Repair and Imaging in Neural Systems (BRAINS)</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>alpha-synuclein</topic> <topic>animal model</topic> <topic>choline acetyltransferase</topic> <topic>cholinergic neurons</topic> <topic>cognition</topic> <topic>dementia</topic> <topic>dopaminergic neurons</topic> <topic>Lewy bodies</topic> <topic>Parkinson&apos;s disease</topic> <topic>magnetic resonance spectroscopy</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-79-1</identifier> <identifier type="oldLupId">3470217</identifier> <part> <detail type="volume"> <number>2013:11</number> </detail> <extent unit="pages"> <total>158</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-02-08T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>ab035615-de98-4559-9615-33d9d9e4ac39</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:28+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:28+02:00</recordDateApproved> </recordInfo> </mods>

Due to the infiltrative growth of the tumor, surgery will never be radical. Radiation and chemotherapy only marginally improve the poor prognosis due to the ability of the GBM to develop resistance towards these treatments. Therefore it is of great importance to find new efficient treatment modalities. &lt;br/&gt;&lt;br&gt; The aim with this thesis was to develop and evaluate a cytokine based immunotherapy as treatment for GBM in both an experimental mouse glioma model as well as in patients suffering from GBM.&lt;br/&gt;&lt;br&gt; In paper I we demonstrate the establishment of a GM-CSF and IFNγ based immunotherapy in the mouse glioma model, GL261. Mice with intracranial gliomas were immunized intraperitoneally with GL261 cell genetically modified to produce GM-CSF combined with recombinant IFNγ. This combination synergistically enhanced survival to 90%. In paper II-III we investigated the immune responses elicited by these immunizations both systemically as well as locally in the tumor. We found that the immunizations with GM-CSF and IFNγ were highly dependent on T-cells for mediating survival of the mice. In paper IV we monitored the immune responses elicited in GBM patients receiving IFNγ based immunotherapy using ELIspot and CBA.&lt;br/&gt;&lt;br&gt; Immunotherapy enhances the patient’s own antitumoral immune responses otherwise suppressed by the tumor. We believe that this treatment, in combination with conventional treatments such as surgery,&lt;br/&gt;&lt;br&gt; radiotherapy and chemotherapy, has a great promise for the future treatment of patients with GBM.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9af6292f-3c03-498b-a905-77a564fb834e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="avh_KarinEnellSmith.pdf">https://portal.research.lu.se/files/3145346/1145934.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2209382</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Tumor Immunology</topic> <topic>Immunotherapy</topic> <topic>Glioma</topic> <topic>Mouse</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-09-5</identifier> <identifier type="oldLupId">1145924</identifier> <part> <detail type="volume"> <number>2008:56</number> </detail> <extent unit="pages"> <total>112</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-24T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>9af6292f-3c03-498b-a905-77a564fb834e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:33+02:00</recordDateApproved> </recordInfo> </mods>

However, the current classification of gliomas is highly subjective and even inaccurate in some cases, which leads to clinical confusion and hinders the development of targeted therapies. EGFR and PDGFRA play crucial roles in glia development and glioma pathogenesis. In this thesis we aim to establish a glial genesis-guided molecular classification scheme for gliomas based on the genes co-expressed with EGFR or PDGFRA and to clarify the clinical relevance and the mechanism of PDGFRA expression in different glioma subtypes. We also aim to investigate the role of cell surface PDGFRA expression in regulating glioma cell proliferation.&lt;br/&gt;&lt;br&gt; In order to establish a glial genesis-guided classification scheme, we identified 69 genes co-expressed with EGFR (EM) or PDGFRA (PM) as classifiers. Using these 69 classifiers, gliomas are clarified into EM (highly expressing EM genes), PM (highly expressing PM genes), and EMlowPMlow (lowly expressing both EM and PM genes) subtypes in a morphology-independent manner. Our results showed that besides their distinct patterns of genomic alterations, EM gliomas were associated with higher age at diagnosis, poorer prognosis, stronger expression of neural stem cell genes and astrogenesis genes, while PM and EMlowPMlow gliomas were associated with younger age at diagnosis and better prognosis. PM gliomas were enriched in the expression of oligodendrogenesis genes, whereas EMlowPMlow gliomas were enriched in the signatures of mature neurons and oligodendrocytes. These findings constitute a framework for improving molecular diagnosis and identifying therapeutic targets to combat gliomas. &lt;br/&gt;&lt;br&gt; To investigate the clinical relevance of PDGFRA in gliomas, the clinical outcomes of gliomas with the top 25% of PDGFRA expression levels (PDGFRA-high) were compared with the gliomas with lowest 25% of PDGFRA expression levels (PDGFRA-low). We found that PDGFRA-high gliomas contained nearly all morphological subtypes, which was associated with frequent IDH1 mutation, 1p LOH, 19q LOH, less EGFR amplification, younger age at disease onset and better survival compared to PDGFRA-low gliomas. We also found that the PDGFRA expression can be induced and maintained by fibroblast growth factor 2 (FGF2) in primary glioma cells. FGF2-dependent maintenance of PDGFRA expression was concordant with the maintenance of a subset of gliogenic genes and higher rates of cell proliferation. Our findings suggest a role of FGF2 in regulating PDGFRA expression in the subset of gliomas.&lt;br/&gt;&lt;br&gt; To investigate the role of cell surface expression of PDGFRA in regulating cell proliferation, we compared the growth rate of primary glioma cells having high cell surface PDGFRA expression level with the glioma cells having low cell surface PDGFRA expression level. We demonstrated that glioma cell proliferation correlated with the extent of surface expression of PDGFRA in both glioma cell lines and their corresponding tumor samples. We also found that MEK inhibitor U0126 treatment can decrease the surface PDGFRA expression and result in deviation of PDGFRA from endosomal trafficking and recycling compartment to the Golgi network in a reversible, dose- and time-dependent manner without affecting total PDGFRA expression. U0126 mediated down-regulation of PDGFRA surface expression correlated with diminished cell proliferation. Our findings suggested that the trafficking of PDGFRA in glioma cells is regulated by ERK activity and can potentially be manipulated to combat glioma growth.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Gliom är den vanligaste typen av hjärntumörer hos vuxna. Den mikroskopiska klassificeringen av de olika formerna av gliom är subjektiv och i vissa fall t.o.m. felaktig, vilket leder till klinisk oklarhet som kan hindra utvecklingen av terapier som riktas mot speciella egenskaper som kännetecknar speciella typer av gliom. EGFR och PDGFRA är en cellreceptor som har en central roll i utvecklingen av hjärnans normala gliavävnad (vävnad som omger nervcellerna), och har en analog huvudroll i gliavävnadens motsvarande tumör–omvandling till gliom. Denna avhandling syftar till att dels etablera en molekylär klassifikation av gliomen på basen av den stegvisa utmognaden av de olika typerna av normala gliaceller och dess association med gener som uttrycks tillsammans med generna för cellreceptorerna EGFR eller PDGFRA, dels klargöra mekanismen och den kliniska relevansen för uttrycket av PDGFRA i olika typer av gliom, samt studera den roll PDGFRA lokaliserat till cellytan har för reglering av gliomcellers delningshastighet.&lt;br/&gt;&lt;br&gt; För att etablera en molekylär gliomklassificering baserad på den normala gliavävnadens utmognad identifierades 69 gener som var aktiva tillsammans med generna EGFR (EM) respektive PDGFRA (PM). Utan hänsyn till mikroskopiskt utseende klassificeras gliom från olika patienter i 3 grupper: EM (EM-gener uttrycks starkt), PM (PM-gener uttrycks starkt) och EMlowPMlow (lågt uttryck av både PM- och EM-gener). Resultatet visar att EM-gliom har starkare uttryck av omogna nervcellsgener och gener associerade med en typ av gliaceller (astroglia), sämre prognos för patienten som insjuknar vid högre ålder. PM och EMlowPMlow är associerade med bättre prognos och lägre ålder vid insjuknandet. PM-gliom har starkare uttryck av gener associerade med en annan typ av gliaceller (oligodendrocyter) liksom EMlowPMlow. De senare har starkare uttryck av gener associerade med mogna nervceller. Dessa resultat utgör en bas för att förbättra den molkylära diagnosticeringen och för att identifiera molkylära målstrukturer/mekanismer för riktad terapi.&lt;br/&gt;&lt;br&gt; Den kliniska relevansen av PDGFRA-uttryck i gliom har också analyserats genom att jämföra det kliniska utfallet för gliompatienter som har gliom med de 25% högsta uttrycken med patienterna med de 25% lägsta uttrycken. De höguttryckande gliomen innefattar nästan alla mikroskopiskt skilda typer av gliom, har lågt uttryck av EGFR och har ofta vissa specifika genmutationer, och patienterna insjuknade vid lägre ålder och hade bättre prognos än patienterna med lågt PDGFRA-uttryck. En tillväxtfaktor för bindvävsceller (FGF2) visas kunna inducera uttrycket av PDGFRA hos gliomceller i vävnadskultur. Graden av PDGFRA-uttryck på gliomcellers yta visas korrelera med cellernas delningshastighet. &lt;br/&gt;&lt;br&gt; Aktiveringen av ett enzym (MEK) utgör ett viktigt steg i den kaskad av molekylära interaktioner som leder från att en receptor internaliseras till att responderande gener aktiveras i cellens kärna. En hämmare av MEK visas minska PDGFRA-uttrycket på cellytan men däremot inte cellens totala PDGFRA. Det minskade receptoruttrycket på cellytan uppfattas vara beroende på en hämning av signalering av återtransport av internaliserade receptorer till cellytan. Att cellens totala PDGFRA inte minskar kan hänga samman med att en annan väsentlig molekyl (ERK) i de aktuella signalvägarna har visats få kompensatoriskt ökat uttryck som en långsam effekt av MEK-hämmaren. Hämmaren framkallar en minskad delningshastighet hos gliomceller i vävnadsodling, vilket går parallellt med det minskade PDDGFRA-uttrycket på cellytan. Den ökade insikten i den molekylära styrningen av PDGFRA på cellytan och därigenom delningshastigheten kan tänkas öppna för ny terapiutveckling.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/dbb54355-4a3f-4a16-8398-8baf22776ee8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="dongfeng&apos;s_thesis.pdf">https://portal.research.lu.se/files/3146195/4114072.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1013607</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Gliomas</topic> <topic>classification</topic> <topic>EGFR</topic> <topic>PDGFRA</topic> <topic>FGF2</topic> <topic>surface expression</topic> <topic>cell proliferation</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-78-9</identifier> <identifier type="oldLupId">4114009</identifier> <part> <detail type="volume"> <number>2013:106</number> </detail> <extent unit="pages"> <total>164</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-10-02T09:30:00+02:00</dateOther> <recordInfo> <recordIdentifier>dbb54355-4a3f-4a16-8398-8baf22776ee8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:41+02:00</recordDateApproved> </recordInfo> </mods>

The global warming is especially dominant in the Arctic, and these areas are vul-nerable to climate change. It is therefore important to quantify and understand the processes affecting the C dynamics in these regions. In this thesis, the land-atmosphere exchange of C, with an emphasis on methane (CH4), was measured in a high-Arctic wet tundra ecosystem (Rylekærene) in Zackenberg, north-eastern Greenland. &lt;br/&gt;&lt;br&gt; Rylekærene was a heterogeneous area concerning the source strength of CH4 and concerning which environmental variables that best determine the CH4 fluxes. For the central parts of Rylekærene, temporal variability in CH4 fluxes was well correlated with soil temperature, gross primary production (GPP), active layer thickness and soil organic acids. The spatial variability in CH4 fluxes was closely correlated to water table depth (WtD), species compo-sition and soil organic acids. The CH4 fluxes remained low during autumn and early winter of both 2008 and 2009. The central parts of Rylekærene acted as a C source during the warmer and wetter measurement season of 2008, whereas it was a C sink during the colder and drier measurement season of 2009.&lt;br/&gt;&lt;br&gt; At a site at the edge of Rylekærene, CH4 emissions were lower than at the central parts of the fen, most likely because of lower WtD and different plant species composition. At this site, the variability in CH4 flux was not explained by any of the above-mentioned factors. Increases in CH4 fluxes coinciding with soil freezing after the growing seasons were observed here in 2007, 2009 and 2010.&lt;br/&gt;&lt;br&gt; Changes in peak growing season GPP 1992 to 2008 was investigated by combining satellite data with ground-based GPP measurements. The modeled results show a substantial increase in peak growing season GPP during this period. The GPP increase was accompanied by a strong increase in air tem-perature, possibly indicating that the increase in GPP was climate-driven.&lt;br/&gt;&lt;br&gt; Changes in CH4 fluxes 1997-2010 was studied by combining satellite data with CH4 flux measurements. During 1997-2010, there were no major changes in modelled CH4 fluxes in Rylekærene, and during this period no trend in soil temperature at 10 cm depth and WtD were seen. However, as changes both in temperature and hydrology are expected as global warming continues, it can be assumed that such changes will have strong effects on the land-atmosphere exchange of C in wet tundra ecosystems in the future.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Under den senaste tiden har problematiken med klimatförändringarna debatterats livligt. För att kunna förutspå den framtida omfattningen av klimatförändringarna och vilka konsekvenser dessa kommer att ha är det ytterst relevant att känna till utbytet av växthusgaser mellan atmosfär och jordens alla ekosystem. Arktiska ekosystem är ytterst känsliga för den globala uppvärmningen. Därtill har temperaturökningen varit större i dessa områden och är förutspådd att bli ännu större i framtiden. Två växthusgaser av extra stor betydelse är koldioxid och metan.&lt;br/&gt;&lt;br&gt; De arktiska ekosystemen spelar dessutom en extra stor roll i kolutbytet mellan mark och atmosfär. Våtmarker på tundran är kalla, vattenfyllda och syrefattiga, vilket gör att nedbrytningen av dött organiskt material sker långsamt. Eftersom detta pågått sedan den senaste istiden, har stora mängder kol ansamlats i marken i dessa områden. Ca 16 % av jordens yta är täckt av permafrost, men 50% av jordens markbunda kol är lagrad i dessa områden. Dessutom gör dessa förhållandena att en stor del av slutprodukten av nedbrytningen av dött organiskt material är metan. Jag presenterar i denna avhandling studier av utbytet av koldioxid och metan mellan mark och atmosfär i en högarktisk våtmark belägen på Nordöstra Grönland. &lt;br/&gt;&lt;br&gt; Mina studier visade att våtmarken fungerade som en kolkälla under den varma och fuktiga mätperioden 2008. Medan den var en kolsänka under den kallare och torrare mätperioden 2009. Variationen i metanutbytet styrdes av marktempertur, växternas produktivitet, halt av substrat för metanproduktion (organiska syror), vattennivån i marken, samt växternas artsammansättning. &lt;br/&gt;&lt;br&gt; Jag har även undersökt växternas koldioxidupptag mellan 1992 och 2008 genom att kombinera fältmätningar av koldioxid med satellitbilder. Mina resultat visade på en kraftig ökning av koldioxidupptaget under denna tidsperiod. Under samma period skedde även en kraftig ökning av lufttemperaturen, vilket tyder på att det ökade koldioxidupptaget var klimatrelaterat. Jag studerade också metanutbytet mellan 1997 och 2010. Jag fann inga indikationer på förändringar i varken metanutsläpp eller i de faktorer som kraftigast styr metanutsläppen från våtmarken, d.v.s. marktemperatur på 10 cm djup och vattennivå. &lt;br/&gt;&lt;br&gt; Den globala uppvärmningen förutspås att fortgå i framtiden och globala klimatmodellerna förutspår framtida förändringar i såväl temperatur som nederbörd. Resultaten jag presenterar i denna avhandling visar på att dessa förutspådda framtida klimatförändringen kan ha en stark påverkan på kolcykeln i de högarktiskta ekosystemen.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5756445a-9bb7-45d7-bca8-0604ed55f449</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="1._Kappa.pdf">https://portal.research.lu.se/files/3147087/1789478.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2546935</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lunds universitets geografiska institution</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>carbon</topic> <topic>methane</topic> <topic>carbon dioxide</topic> <topic>climate change</topic> <topic>Arctic</topic> <topic>NDVI</topic> <topic>NDWI</topic> <topic>micrometeorology</topic> <topic>remote sensing</topic> <topic>chamber</topic> <topic>tundra</topic> </subject> <subject authority="lup"> <topic>Physical Geography</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Meddelanden från Lunds universitets geografiska institution.

Businesses can no longer ignore the environmental impacts of the products outside the borders of their own facilities. Consequently companies are now extending their environmental considerations beyond their internal production to include the environmental performance of their suppliers and supply chains. At the same time, many companies are implementing environmental management systems, certified according to the international standard ISO 14001. Therefore, the question arises, could the structure of an EMS, as outlined in the ISO 14001 be used as an inter-organizational tool for setting, communicating, and monitoring the environmental requirements in the supply chain. &lt;br/&gt;&lt;br&gt; This thesis considers this question and presents the results from recent literature, and practical experiences. It goes on to analyze and discuss the possibilities and potential problems connected to this extended use of the standard. The results establish the importance of building trust and close relationships between the cooperating companies. Trust relates also to credibility of the ISO 14001 and its certification audit. The research suggests better use of the companies’ internal capabilities stemming from implementation of ISO 14001 in order to overcome some of the problems.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/91c10ae8-b2bd-4f12-81c5-cd727632312a</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Exec_Summary.pdf">https://portal.research.lu.se/files/3147322/1479067.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">64661</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>The International Institute for Industrial Environmental Economics</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>ISO 14001</topic> <topic>environmental supply chain management</topic> <topic>environmental management systems</topic> <topic>Corporate environmental management</topic> </subject> <subject authority="lup"> <topic>Other Social Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>IIIEE Dissertation</title> </titleInfo> <identifier type="issn">1402-3016</identifier> <identifier type="isbn">978-91-88902-50-4</identifier> <identifier type="oldLupId">1392626</identifier> <part> <detail type="volume"> <number>2009:3</number> </detail> <extent unit="pages"> <total>121</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-29T13:30:00+02:00</dateOther> <recordInfo> <recordIdentifier>91c10ae8-b2bd-4f12-81c5-cd727632312a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:04:54+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:04:54+02:00</recordDateApproved> </recordInfo> </mods>

Nevertheless, there is still no international consensus regarding how a number of ethical questions related to this research should be answered. Many of these ethical questions create a real challenge to translation of basic research results into clinical applications.&lt;br/&gt;The overall aim of the thesis is to analyse some of the major ethical questions arising at different levels of translation of knowledge generated by preclinical and clinical stem cell research. The questions chosen for analysis have either not yet received much attention in the literature (papers I and IV), or could benefit from ethical analysis of specific examples (papers II and III). This thesis suggests ways to address the same problems in clinical translation of stem cell research results, involving other variables, such as different diseases (papers II and III), or ways to address certain types of ethical questions arising in translational stem cell research as well as in some other areas of biomedical research (papers I and IV). Solutions to the problems analysed in this thesis cannot be offered until the state of knowledge has been improved and until certain fundamental moral questions have been tackled; otherwise, the final balancing of interests and concerns will not be well founded as the results of all four studies indicate.&lt;br/&gt;The thesis explores:&lt;br/&gt;(a) whether there are ethically justified reasons to regulate basic research on human embryonic stem (hES) cells and human-induced pluripotent stem (hiPS) cells differently: a very immediate issue in preclinical research (Paper I);&lt;br/&gt;(b) which groups of patients should be asked to participate in first-in-human clinical studies of stem cell-based therapies, and on what grounds: a very immediate issue in translation of preclinical research results into first clinical application on small numbers of human participants (“frontier research”) (Paper II);&lt;br/&gt;(c) how to prioritize stem-cell-based therapies if and when they become routine, in the face of limited resources: a highly likely issue in translation of knowledge obtained in clinical trials into clinical practice and daily care of patients (Paper III);&lt;br/&gt;(d) whether, under what conditions, and to what extent withdrawal of consent from research involving donated human biological samples should be allowed: an immediate issue in preclinical research (Paper IV).&lt;br/&gt;This thesis is a theoretical work, and the methods used are theoretical approaches. In Paper II and Paper III the concept of stakeholder is important, since the perspectives of different stakeholders play an important role in the analysis conducted in these papers. In both papers the current state of knowledge and knowledge gaps are identified on the basis of the available scientific literature. The possible courses of action are outlined, the stakeholders concerned by the alternative courses of action identified. Their interests are then described and evaluated in the light of certain value premises, e.g. values endorsed by major different types of ethical theories (such as utilitarianism, virtue ethics, as well as human dignity and human rights-based theories) or values enshrined in European and international guidelines, declarations, directives or conventions. These values are applied to the alternatives. Arguments are provided concerning what should be done in the light of the knowledge we have and in the light of value premises. In Paper I and Paper IV the discussion of different arguments expressed in the literature play an important role. These arguments are presented and their ethical relevance is discussed in the light of different types of ethical theories, as in Paper I, or attention is drawn to a number of areas that need to receive greater attention in order for the debate to make progress, as in Paper IV.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4635a7ab-7e6f-4952-a6dc-827eef7cb137</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kristina_Hug.pdf">https://portal.research.lu.se/files/3148875/2629355.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">828683</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Medical Ethics, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Translational stem cell research</topic> <topic>research ethics</topic> <topic>values</topic> <topic>experimental stem cell-based therapies</topic> <topic>patient safety</topic> <topic>treatment efficacy</topic> <topic>treatment accessibility</topic> <topic>first-in-human trials</topic> <topic>Parkinson’s disease</topic> <topic>Huntington’s disease</topic> <topic>priority setting</topic> <topic>right to withdraw</topic> <topic>human biological material</topic> <topic>informed consent</topic> </subject> <subject authority="lup"> <topic>Medical Ethics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-05-0</identifier> <identifier type="oldLupId">2543304</identifier> <part> <detail type="volume"> <number>2012:43</number> </detail> <extent unit="pages"> <total>150</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-06-14T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>4635a7ab-7e6f-4952-a6dc-827eef7cb137</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:07+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:07+02:00</recordDateApproved> </recordInfo> </mods>

They are found&lt;br/&gt;&lt;br&gt; in educational programmes from preschool to university, as well as in broader&lt;br/&gt;&lt;br&gt; educational contexts in the form of medical counsellors, virtual health coaches,&lt;br/&gt;&lt;br&gt; information guides, etc. Since long, they also appear in edutainment and infotainment&lt;br/&gt;&lt;br&gt; settings.&lt;br/&gt;&lt;br&gt; The thesis addresses psychological, cognitive and social aspects of embodied&lt;br/&gt;&lt;br&gt; virtual characters in pedagogical contexts with respect to ‘static visual characteristics’,&lt;br/&gt;&lt;br&gt; i.e. underlying visual characteristics. On the basis of theoretical considerations&lt;br/&gt;&lt;br&gt; as well as several empirical studies, it is argued that users’ visual and&lt;br/&gt;&lt;br&gt; aesthetic experience of embodied pedagogical characters (EPCs) is too important&lt;br/&gt;&lt;br&gt; to be treated as a secondary issue – not the least with respect to central pedagogical&lt;br/&gt;&lt;br&gt; goals to motivate and engage.&lt;br/&gt;&lt;br&gt; The main conclusions of the thesis are: (i) that visual aspects in EPCs can&lt;br/&gt;&lt;br&gt; be related to pedagogical outcomes, (ii) that there may be significant relations&lt;br/&gt;&lt;br&gt; between visual and social characteristics of EPCs and learner characteristics, and&lt;br/&gt;&lt;br&gt; (iii) that EPCs may reproduce stereotypes from everyday real life human-human&lt;br/&gt;&lt;br&gt; interaction, as well as from traditional visual media – but that they simultaneously&lt;br/&gt;&lt;br&gt; harbour a considerable potential to challenge stereotypes.&lt;br/&gt;&lt;br&gt; As a tool for the research community, a framework of a visual graphical design&lt;br/&gt;&lt;br&gt; space is proposed. The framework may scaffold the design of user evaluations,&lt;br/&gt;&lt;br&gt; which often are blurred by uncontrolled visually related variables. With regard to&lt;br/&gt;&lt;br&gt; weak user evaluations, the thesis furthermore argues that there is a problem with&lt;br/&gt;&lt;br&gt; user evaluations based upon the concept of ‘the User’, i.e. an averaged standardized&lt;br/&gt;&lt;br&gt; user. In order to reveal important correlations between agent characteristics&lt;br/&gt;&lt;br&gt; and user characteristics, it is often necessary to identify relevant subgroups of&lt;br/&gt;&lt;br&gt; users rather than to treat the whole user group as an ‘averaged user’.&lt;br/&gt;&lt;br&gt; And finally – virtual agents may have a not yet thought of potential as research&lt;br/&gt;&lt;br&gt; tools …</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a826874b-827c-40ba-b572-aed0931415d8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="phdMH2009_screen.pdf">https://portal.research.lu.se/files/3149322/1389730.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3847803</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Institutionen för designvetenskaper, Lunds Tekniska Högskola, Lunds universitet</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>masculinity</topic> <topic>role modelling</topic> <topic>cognitive styles</topic> <topic>stereotypes</topic> <topic>education</topic> <topic>pedagogical implications</topic> <topic>visual style</topic> <topic>virtual characters</topic> <topic>visual design</topic> <topic>Virtual pedagogical agents</topic> <topic>femininity</topic> <topic>gender</topic> <topic>androgynities</topic> </subject> <subject authority="lup"> <topic>Production Engineering, Human Work Science and Ergonomics</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-628-7804-7</identifier> <identifier type="oldLupId">1389720</identifier> <identifier type="other">ISRN LUTMDN/TMAT --1032--SE</identifier> <part> <extent unit="pages"> <total>240</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-20T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>a826874b-827c-40ba-b572-aed0931415d8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:12+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:12+02:00</recordDateApproved> </recordInfo> </mods>

There are a large number of disorders that can lead to dementia, and neuropathological examination after death is necessary to determine the underlying cause with certainty. The overall aim of this thesis was to investigate neuropathological findings in patients with dementia and neuropathological staging of dementia disorders, the main potential gain being increased epidemiological knowledge and improved neuropathological dementia diagnostics. &lt;br/&gt;&lt;br&gt; We could confirm the generally accepted opinion that on a neuropathological basis, Alzheimer’s disease (AD) is the most common dementia disorder, followed by vascular dementia (VaD) and mixed AD+VaD. Also, in a significant number of patients, the clinical dementia subtype diagnosis does not correspond with the neuropathological findings. Furthermore, degeneration of the nucleus locus coeruleus, often seen already macroscopically, generally indicates the diagnoses Lewy body disease (LBD) or AD among the demented, while a preserved locus coeruleus occurs mainly in VaD and frontotemporal lobar degeneration (FTLD). Moreover, various neuropathological staging systems for AD differ in procedure and targeted pathology, and the choice of system affects the judgement of Alzheimer pathology and hence the final diagnosis. Also, various neuropathological LBD staging systems differ in applicability and to some extent in the judgment of Lewy-related pathology.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3e1acfcd-8e65-44a9-b36b-63004c5792d4</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Brunnstrom_Kappa_G5_slutlig__hog_kv_.pdf">https://portal.research.lu.se/files/3149348/1882987.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3129676</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Dept of Pathology</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Alzheimer disease</topic> <topic>concordance</topic> <topic>dementia</topic> <topic>diagnostics</topic> <topic>frontotemporal lobar degeneration</topic> <topic>grading</topic> <topic>Lewy body disease</topic> <topic>locus coeruleus</topic> <topic>neuropathology</topic> <topic>prevalence</topic> <topic>staging</topic> <topic>vascular dementia</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-83-9</identifier> <identifier type="oldLupId">1882978</identifier> <part> <detail type="volume"> <number>2011:35</number> </detail> <extent unit="pages"> <total>120</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-05-06T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

In Sweden, this&lt;br/&gt;&lt;br&gt; technology dominates the market but is challenged by other competitive production methods.&lt;br/&gt;&lt;br&gt; The criticism concerns issues as for instance short slab spans (limited flexibility for future&lt;br/&gt;&lt;br&gt; refurbishment), long production times, unhealthy work environment and indoor air problems.&lt;br/&gt;&lt;br&gt; Many of these disadvantages are due to the fact that by tradition ordinary low-grade concrete&lt;br/&gt;&lt;br&gt; is used in house building. Extensive concrete materials research on high-performance&lt;br/&gt;&lt;br&gt; concrete (HPC) and self-compacting concrete (SCC) has revealed opportunities to counter the&lt;br/&gt;&lt;br&gt; criticism, but the technologies are not yet utilised in house building to large extent. The&lt;br/&gt;&lt;br&gt; research project aims at investigating the potential of HPC and SCC for competitive&lt;br/&gt;&lt;br&gt; production, structural design and function of structural frames of cast in-situ concrete in house&lt;br/&gt;&lt;br&gt; building.&lt;br/&gt;&lt;br&gt; The first part of the research project is dominated by production studies performed in field&lt;br/&gt;&lt;br&gt; with the aim of investigating the ‘real’ potential of SCC addressing technical/practical and&lt;br/&gt;&lt;br&gt; economical issues. These case studies consist of observations and measurements of the&lt;br/&gt;&lt;br&gt; consequences when normal concrete is replaced by SCC. The result shows that SCC has a&lt;br/&gt;&lt;br&gt; large potential for both increasing the production efficiency and improving the work&lt;br/&gt;&lt;br&gt; environment.&lt;br/&gt;&lt;br&gt; In the second part of the project, the theoretical potential of HPC is investigated by several&lt;br/&gt;&lt;br&gt; parameter studies where HPC is compared with ordinary concrete as well as an interview&lt;br/&gt;&lt;br&gt; study focusing on building process issues. The main conclusions from these studies are that&lt;br/&gt;&lt;br&gt; use of HPC can reduce the production time strongly (by rapid drying and strength&lt;br/&gt;&lt;br&gt; development), increase the slab span significantly (through utilisation of increased tensile&lt;br/&gt;&lt;br&gt; strength and E-modulus) and also increase the building function (increased flexibility,&lt;br/&gt;&lt;br&gt; acoustic and indoor air quality).&lt;br/&gt;&lt;br&gt; When it comes to technical and building process related obstacles for the implementation of&lt;br/&gt;&lt;br&gt; HPC and SCC, these are analysed and described together with proposed solutions.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/85047f80-0aee-4837-b310-59b80141a6c4</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="MP_final_thesis_8_apr_2008.pdf">https://portal.research.lu.se/files/3149450/1057365.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9693870</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Building Materials, LTH, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Multi-storey residential buildings</topic> <topic>Structural frames</topic> <topic>SCC</topic> <topic>Self-compacting concrete</topic> <topic>High-performanceconcrete</topic> <topic>HPC</topic> <topic>Concrete</topic> <topic>Building materials</topic> <topic>Cast in-situ concrete</topic> </subject> <subject authority="lup"> <topic>Materials Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Report TVBM</title> </titleInfo> <identifier type="issn">0348-7911</identifier> <identifier type="isbn">978-91-628-7494-0</identifier> <identifier type="oldLupId">1057357</identifier> <identifier type="other">TVBM-1027</identifier> <part> <detail type="volume"> <number>1027</number> </detail> <extent unit="pages"> <total>274</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-09T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>85047f80-0aee-4837-b310-59b80141a6c4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:14+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:14+02:00</recordDateApproved> </recordInfo> </mods>

Carrying out different case studies, a set of complementary evaluation methods is applied in conducting ex-ante and ex-post evaluation studies. To analyse the attributes and complexities of TWC schemes, the thesis focuses on several aspects, including (i) the modelling of potential impacts, (ii) the identification and analysis of transaction costs, (iii) the investigation of trading patterns and other flexibilities used to achieve cost-effective compliance, (iv) the level of energy-saving effectiveness under TWC schemes, (v) the use of cost-benefit analysis, and (vi) the application of multi-criteria evaluation. The findings help answer questions concerning the impacts and outcomes of TWC schemes and identify critical endogenous and exogenous conditions that affect their performance.

They bind intracellular peptides and present them to the immune system thus providing a readout to cytotoxic T-cells about the status of a cell. Maturation of the HLA-I molecule includes peptide binding in the endoplasmic reticulum with the assistance of several other proteins collectively called the antigen processing machinery (APM). One of these proteins, tapasin, is of particular interest as it is dedicated to HLA-I and plays a key role in the selection and binding of peptides that induce stable HLA-I molecules.&lt;br/&gt;&lt;br&gt; In this thesis I have studied HLA-I maturation, and tapasin in particular, both biochemically and in tumor material. The first paper is a study of HLA-I folding in the presence and absence of a part of recombinant tapasin (tpn1-87). Here we studied how different HLA-I allomorphs depend on tapasin and the influence of peptide length. This is the first study where a large number of HLA-I allomorphs have been simultaneously analyzed for tapasin facilitation. We found that the influence of peptide length for the different allomorphs increased with their tapasin dependence. In paper II and III we studied HLA-I, tapasin and other APM proteins in tumor sections and cell lines of glioblastoma multiforme (GBM). In tumors APM proteins are commonly downregulated as a strategy to evade the immune system. We also found the APM proteins in our tumor material to be highly dysregulated with strongly linked HLAI&lt;br/&gt;&lt;br&gt; and tapasin expression. In tumor tissue sections HLA-I and tapasin expression also correlated with survival of GBM patients. High resolution HLA-I typing allowed us to study the HLA-I allomorphs expressed in GBM patients and also each allomorph’s tapasin dependence. We found that GBM patients display HLA-I allomorph profiles with mixed dependency of tapasin, similar as in a healthy cohort. In addition we show that tapasin deficient cells present suboptimally loaded HLA-I molecules on the cell surface. By exogenous addition of high affinity peptides we were able to increase the stability of presented HLA-A*02:01 molecules. The tapasin dependency of each allomorph as well as composition and proportions of HLA-I allomorphs presented on the cell surface is of importance not only for&lt;br/&gt;&lt;br&gt; mechanistic understanding but also for immunotherapy settings in different diseases. GBM is an aggressive brain tumor with poor prognosis and there are high demands for new and more effective treatments. We propose individualized immunotherapy protocols where tapasin expression and tapasin dependency of allomorphs expressed in each patient are taken into consideration to improve the selection of peptide:HLA-I combinations for peptide vaccines.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/10839f48-334a-4ffe-b964-e97224562ab1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis_Camilla_Thuring_2.pdf">https://portal.research.lu.se/files/3149576/5159989.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7415833</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Antigen Presentation</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Tapasin</topic> <topic>HLA-I</topic> <topic>tumor</topic> <topic>antigen presentation</topic> </subject> <subject authority="lup"> <topic>Pharmacology and Toxicology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-107-1</identifier> <identifier type="oldLupId">5152928</identifier> <part> <detail type="volume"> <number>2015:28</number> </detail> <extent unit="pages"> <total>146</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-03-20T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>10839f48-334a-4ffe-b964-e97224562ab1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:16+02:00</recordDateApproved> </recordInfo> </mods>

Matrix components released into body fluids by proteolytic cleavage can be used as biomarkers of ongoing processes. This thesis focuses on proteolytic degradation of the proteoglycan aggrecan with the overall aim to study the potential of aggrecan fragments as biomarkers in knee OA.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Methodology/Principal findings: Using neoepitope specific antibodies in Western blots, aggrecan fragments were identified in knee cartilage and synovial fluid (SF) pooled from individuals with a wide spectrum of disease. Aggrecanases were found to dominate aggrecan proteolysis in disease, although a contribution of matrix metalloprotease (MMP) activity was noted. Western blot quantification in individual samples showed that the proportion of aggrecan released into SF generated by aggrecanases varied in disease, and was higher in diagnostic groups associated with high disease activity. Quantification by ELISA of SF ARGS showed that SF ARGS better distinguished samples from patients with knee joint disease from samples obtained from knee healthy individuals than aggrecan measures not specific for this neoepitope. In patients meniscectomized 18 years earlier, SF ARGS levels were inversely associated with progression of radiographic OA.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Conclusions: Aggrecanase is the dominating protease in human knee OA and its activity toward the aggrecan interglobular domain (IGD) is elevated in disease. SF levels of aggrecan ARGS fragments generated by this IGD activity can be used as biomarkers and has diagnostic as well as prognostic capabilities.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Vid vår vanligaste ledsjukdom, artros, sker en progressiv förstöring av ledbrosk beroende på en störd balans mellan nedbrytning och nybildning av broskets extracellulära matrix. Ledbrosket utsätts för stort slitage och broskceller – kondrocyter – glest positionerade i vävnaden står för både nysyntes av broskmolekyler och för huvuddelen av nedbrytandet av slitna molekyler genom syntes av proteinklyvande enzymer – proteaser. Två familjer av proteaser har visat sig vara viktiga i omsättningen av ledbrosket: matrix metalloproteaser (MMP) och aggrekanaser. Dessa klyver framför allt kollagen II och aggrekan som, förutom vatten, är de två huvudbeståndsdelarna i ledbrosk. Kollagen II utgör ungefär 3/4 av vävnadens torrvikt, bildar ett fibrillerat nätverk som ger ledbrosket dess draghållfasthet, samt förankrar aggrekan och andra proteiner i vävnaden. Aggrekan utgör ungefär 1/5 av vävnadens torrvikt och är den molekyl i ledbrosket som ger det dess stötdämpande förmåga, detta genom sin stora negativa laddning vilken attraherar motjoner som i sin tur skapar det osmotiska tryck som håller vatten kvar i brosket.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det övergripande syftet med denna avhandling var att utvärdera om klyvningsfragment av aggrekan utsläppta från brosket till den omgivande ledvätskan kan användas som indikatorer, eller biomarkörer, för artros. En biomarkör är en biologisk variabel som speglar en fysiologisk förändring till följd av t.ex. sjukdom. Biomarkörer kan användas vid diagnostisering, för att förutsäga vem som löper risk för att drabbas eller förvärras, eller för att följa om en behandling har effekt. De kan också användas för att studera bakomliggande biologiska mekanismer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I första delarbetet gjordes en noggrann kartläggning av aggrekanfragment i brosk och ledvätska från ett stort antal patienter med varierande grad av artros eller knäskada. Antikroppar specifika för de nya aminosyresekvenser som blottläggs vid proteasklyvning, så kallade neoepitoper, användes i Western blot teknik. Denna teknik vidareutvecklades för att grovt kunna kvantifiera olika fragment. Kartläggningen i kombination med kvantifiering av några huvudfragment av aggrekanmolekylen visar att proteas i aggrekanasfamiljen ADAMTS spelar en huvudroll vid omsättningen av aggrekan i artros, även om aggrekanfragment kluvna av proteas ur familjen MMP också förekom.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Fördelen med kvantifieringsmetoden utvecklad i första delarbetet är att man, till skillnad från den vanligaste antikroppsbaserade kvantifieringsmetoden ELISA, kan särskilja och kvantifiera fragment av olika storlek samtidigt. Detta utnyttjades i andra delarbetet där ledvätskor från ett trettiotal patienter med olika ledsjukdomar jämfördes med knäfriska individers ledvätskor. Ledvätskenivåer av fragment kluvna av aggrekanas i två olika domäner av aggrekan jämfördes sinsemellan och med generellt aggrekaninnehåll. Resultaten identifierar fragment med den aggrekanasgenererade neoepitopen ARGS som en potentiell biomarkör och visar att andelen aggrekan med denna neoepitop varierar mellan olika ledsjukdomar och är större vid hög sjukdomsaktivitet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Kvantifiering i Western blot kräver dock stora provmängder samt tidskrävande upparbetning och lämpar sig därför sämre för större provserier. I tredje delarbetet utökades antalet försökspersoner till 295 och ledvätskenivåer av ARGS-aggrekan mättes med en ELISA. Resultaten visar på mycket förhöjda ledvätskenivåer av ARGS-aggrekan vid ledsjukdom, i synnerhet vid inflammation och kort tid efter knäskada, men även vid knäartros. Lång tid efter knäskada var ARGS-nivåerna låga, men fortfarande förhöjda jämfört med nivåerna hos knäfriska och med mycket större spridning mellan olika individer. Jämfört med andra metoder som mäter generella nivåer av aggrekan, oavsett var fragmenten kluvits, är ledvätskenivån av ARGS avsevärt bättre på att särskilja prover från ledsjuka från de från knäfriska. Ledvätskenivåer av ARGS-aggrekan visades alltså vara en god biomarkör för ledsjukdom.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I fjärde delarbetet studerades ARGS-aggrekan i relation till sjukdomsprogress vid artros. I 141 patienter vilka opererats för meniskskada 18 år tidigare, mättes ledvätskekoncentrationen av ARGS-aggrekan och jämfördes med förändring av röntgenologiska kännetecken för artros 7,5 år senare. ARGS-nivåerna i ledvätska 18 år efter operation fanns vara samma som i kontrollindivider som inte opererats. Inom dessa till synes normala nivåer, visade sig risken för röntgenologisk sjukdomsprogress minska med ökande ledvätskenivåer av ARGS-aggrekan, vilket var förvånade då andra studier visat på förhöjda nivåer vid ledsjukdom. En trolig förklaring, som skulle innebära minskad risk för sjukdomsprogress med ökande ledvätskenivåer av ARGS inom det normala spannet, är en ökad nysyntes av aggrekan som till dels inkorporeras i vävnaden, men till dels klyvs av aggrekanas och sipprar ut i ledvätskan.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar jag i denna avhandling att proteas tillhörande familjen aggrekanas är dominerande i artros och att aggrekanfragment med neoepitopen ARGS uppkommen genom aggrekanasklyvning är en biomarkör med diagnostisk så väl som prognostisk förmåga.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/fdde2dda-2c46-463c-a0a4-bd075d50475c</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Dissertation_Staffan_Larsson_20100514.pdf">https://portal.research.lu.se/files/3149812/1593016.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4522905</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund Univerity, Faculty of Medicine, Clinical Sciences Lund, Department of Orthopaedics, SE-221 84 Lund, Sweden</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>protease</topic> <topic>Aggrecan</topic> <topic>osteoarthritis</topic> <topic>proteoglycan</topic> <topic>knee injury</topic> <topic>biomarker</topic> <topic>aggrecanase</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-70-2</identifier> <identifier type="oldLupId">1593007</identifier> <part> <detail type="volume"> <number>2010:55</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-14T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>fdde2dda-2c46-463c-a0a4-bd075d50475c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:19+02:00</recordDateApproved> </recordInfo> </mods>

The general proposition of the thesis is that personality traits are stable dispositons and therefore predispose an individual to behave or act in a specific manner (Costa &amp;amp; McCrae, 1976). Additionally, another important determinant of academic performance is students´ approaches to learning, the way someone studies and makes sense of a particular school subject (Biggs, 1999). Study I examined how personality traits, divided into facets, predict academic performance in different school subjects. The results from several SEM-analyses showed that personality, specifically Conscientiousness, has a positive influence on academic performance. In addition, there was a negative relation between Extraversion and academic performance and a positive relation between Neuroticism and academic performance. There were also interesting findings on the facet levels for all traits. The major conclusion of this study is that personality traits, both on the factor level and on the facet level, are important to academic performance in general, but sometimes more specifically to different school subjects. In Study II, the aim was to investigate the unique contribution of learning approaches to academic performance. A second aim was to explore possible gender differences in learning approaches. It was found that learning approaches contributed uniquely to academic performance, over and above personality and general intelligence. Differences between boys and girls were found, both with respect to the use of learning approaches and the consequences of these learning approaches for performance results. Based on a longitudinal design, the aim of Study III was to explore to what extent personality traits predict academic performance. Conscientiousness, Extraversion and Neuroticism were found to predict overall academic performance. Results suggest that personality traits, as measured at the age of 16, can predict academic performance at the age of 19, and more specifically, the grades of conscientious students improved from age 16 to age 19. This study extends previous work by assessing the relationship between the Big Five and academic performance over a three-year period.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Personlighetspsykologer har i mer än ett århundrade försökt att identifiera och beskriva observerbara skillnader mellan individer. Bland dessa indiduella skillnader har intelligens och personlighet fått stor uppmärksamhet inom skolvärlden, liksom elevers förhållningssätt till sitt lärande. Kunskapen om vilka faktorer som påverkar studieresultat har viktiga praktiska konsekvenser för lärande och utbildning. Det finns också andra värden i att kunna förutsäga studieresultat: för det första, en stor del av bruttonationalprodukten går åt till utbildningsåtgärder, för det andra, många unga männmiskor kommer att utbilda sig under många år. En tredje faktor är att studieresultat värderas högt så alla steg i att förstå studieresultat kommer att få betydande konsekvenser. &lt;br/&gt;&lt;br&gt; Det övergripande syftet med denna avhandling var att undersöka i vilken utsträckning personlighetsdrag och förhållningssätt till lärande bidrar till akademisk prestation, efter kontroll av intelligens. I linje med den ökande acceptansen av en bred faktoriell modell av personligheten, fem-faktor modellen, som innehåller dimensiorna Öppenhet, Samvetsgrannhet, Extraversion, Neuroticism och Samstämmighet, är grundantagandet i denna avhandling att dessa är relativt stabila egenskaper och därmed kan predisponera en individ att bete eller agera på ett specifikt. sätt.&lt;br/&gt;&lt;br&gt; Huvudsyftet med Stude I var att undersöka om personlighetsegenskaper på facettnivå bättre predicerar skolframgång än själva faktorerna. Genom att dela upp betygen på respektive ämne visade resultatet av flera SEM-analyser att Samvetsgrannhet, både på faktor-nivå och på facett-nivå, predicerar skolframgång. För de andra faktorerna visade resultatet på en negativ relation mellan Extravcersion och skolframgång och på en positiv relation mellan Neuroticism och skolframgång. På facettnivå fanns flera intressanta fynd, liksom på relationen till de olika skolämnena. Det fanns också intressanta fynd som visade på strukturella skillnader mellan könen; relationen mellan Samvetsgrannhet och IQ var positiv för flickor medan den var negativ för pojkar. Den största slutsatsen från den här studien var att personlighetsegenskaper, både på faktor-nivå och på facett-nivå, inverkar på akademisk prestation i olika ämnen vilket kan inspirera lärare till att tillämpa nya metoder som är anpassade till elevers specifika personlighetstyper.&lt;br/&gt;&lt;br&gt; I Studie II undersöktes i vilken grad inlärningsstilar bidrar till skolframgång, efter kontroll av personlighet och intelligens. Eventuella könsskillnader avseende inlärningsstilar undersöktes också. Genom att använda en kombination av hierarkiska och stegvisa regressionsanalyser, visade resultatet att inlärningsstilar svarade för 6 % av variansen i akademisk prestation för flickor och 16 % för pojkar. Resultatet visade också på stora variationer mellan könen och vilken inlärningsstil som föredras i respektive ämne. Sammantaget visar resultatet från studien att inlärningsstilar är oberoende av personlighet och bidrar till att predicera akademisk framgång.&lt;br/&gt;&lt;br&gt; Genom att använda en longitudinell design i Studie III, möjliggjordes syftet att undersöka den prediktiva validiteten av personlighet på akademisk framgång. Som väntat var Samvetsgrannhet den största enskilda prediktorn över tid vilket kan förklaras av innebörden i egenskapen, såsom ordningsam, uthållig, organiserad och målinriktad, vilka alla är kända för att ha en betydande roll i elevers studievanor och den anstängning de lägger på sina studier. En av slutsatserna av studien är att Samvetsgrannhet, Extraversion och Neuroticism vid 16 års ålder predicerar skolframgång vid 19 års ålder. Ytterligare fynd som gjordes var att en relativ ökning av Samvetsgrannhet från 16 till 19 år också ger en relativ ökning av akademisk prestation vid 19 år. Resultaten som presenteras i avhandlingen har såväl teoretiska som praktiska implikationer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/876766c4-5c42-4303-b930-d8b221273ac2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa_final_version_121114.pdf">https://portal.research.lu.se/files/3152866/3217378.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">18699817</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Pia Rosander</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Personality traits</topic> <topic>Intelligence</topic> <topic>approaches to learning</topic> <topic>longitudinal</topic> <topic>SEM-analyses</topic> <topic>adolescents</topic> <topic>high school</topic> <topic>gender differences</topic> </subject> <subject authority="lup"> <topic>Psychology</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-3</identifier> <identifier type="oldLupId">3217342</identifier> <part> <extent unit="pages"> <total>141</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-01-25T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>876766c4-5c42-4303-b930-d8b221273ac2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:22+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:22+02:00</recordDateApproved> </recordInfo> </mods>

There is growing evidence that glaucoma is a disease of the entire retina and not only the inner retina. Best vitelliform macular dystrophy (BVMD) affects the retinal pigment epithelium and is considered a model system for the more common blinding disease, age-related macular degeneration.&lt;br/&gt;&lt;br&gt; The aim of the work presented in this thesis was to analyse clinical, electrophysiological and morphological outcomes before and after treatment or follow-up of patients with different types of glaucoma such as primary open-angle glaucoma (POAG), angle-closure glaucoma (ACG) and neovascular glaucoma (NVG) and/or BVMD. Full-field electroretinography (full-field ERG), which reflects total retinal function, multifocal electroretinography (mfERG), which reflects central retinal function, optical coherence tomography (OCT), which analyses central retinal structure, and molecular genetic analysis are objective tools used to evaluate patients in this study.&lt;br/&gt;&lt;br&gt; Full-field ERG showed a clear reduction in the entire retinal function in NVG patients before treatment and a worsening of the total retinal function after treatment, especially when bevacizumab was used. The impaired retinal function, compared with controls, was confirmed by full-field ERG in POAG patients. Surgical reduction of the intraocular pressure in POAG patients improved both the central retinal function and structure, as demonstrated by mfERG and OCT, suggesting that the entire retina is affected in glaucoma.&lt;br/&gt;&lt;br&gt; The presence of biallelic mutations in the bestrophin-1 gene (BEST1) was associated with severe BVMD, demonstrated by full-field ERG, mfERG and OCT results. BVMD in patients with the well-known p.Y85H mutation in the BEST1 gene was also associated with developmental abnormalities in the anterior segment including ACG. No mutations of the MITF and CRX genes or disrupted pre-mRNA splicing were found in the BVMD-affected family studied.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1dc4c880-8ed1-431a-9bbb-f6f04b1349e6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_G5_hoger_med_artiklar.pdf">https://portal.research.lu.se/files/3152972/2204987.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4847913</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Ophthalmology, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Glaucoma</topic> <topic>BVMD</topic> <topic>BEST1</topic> <topic>full-field ERG</topic> <topic>mfERG</topic> <topic>OCT</topic> </subject> <subject authority="lup"> <topic>Ophthalmology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-46-8</identifier> <identifier type="oldLupId">2204981</identifier> <part> <detail type="volume"> <number>2011:97</number> </detail> <extent unit="pages"> <total>152</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-11-25T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>1dc4c880-8ed1-431a-9bbb-f6f04b1349e6</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:24+02:00</recordDateApproved> </recordInfo> </mods>

Therefore, it is crucial that we understand the various risk factors that shape unsafe sexual behaviours among young people in Uganda. The overall aim of this thesis was to gain a deeper understanding of the various factors that have an association with risky sexual behaviours among Ugandan university students, focusing on a gender perspective. This knowledge can contribute to effective policy formulation and implementation of programs. In 2010, 1,954 students participated in a cross-sectional&lt;br/&gt;&lt;br&gt; study and the data was collected using a self-administered questionnaire. Logistic regression was used as the main analytical&lt;br/&gt;&lt;br&gt; tool for the analysis and effect modification analysis was conducted for some of the associations. Study I found that there was an association between non-use of contraception and socio-demographic factors, relationship status, and alcohol consumption. The socio-demographic determinants that affected this association were different for males and females. Early sexual debut was found to modify the effect of this association. Study II concluded that there was an association between alcohol consumption and the experience of sexual coercion among Ugandan university students. Frequent consumption of alcohol on the occasion of sexual intercourse and poor mental health were found to have a synergistic effect with recent&lt;br/&gt;&lt;br&gt; experience of sexual coercion. Study III demonstrated an association between self-reported poor academic performance and inconsistent condom use with a new sex partner. Females who were poor academic performers were found to be at a higher risk of inconsistent condom use compared to their male counterparts. Study IV showed that there is an association between low condom efficacy and inconsistent condom use with a new sex partner. Gender differences were observed: females with low condom efficacy were at a higher risk of inconsistent condom use, in comparison to males. Our studies concluded that the key factors that contribute towards risky sexual behaviours among Ugandan university students were socio-demographic factors, relationship status, alcohol consumption, academic performance, and condom efficacy. Unequal gender power relations in this region further aggravates the sexual risk behaviours. Therefore, we need to create a policy action environment (not merely policies) in which sexual and reproductive health rights is addressed by raising awareness among&lt;br/&gt;&lt;br&gt; males and females. In universities this could be achieved through skill building programs such as sex education, peer counseling, and partner communication, with a special focus on women by providing them skills for negotiating condom and contraceptive use. These programs need to address the socio-cultural and gender perspectives in addition to focusing on safe sex and sexual rights.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/480d8887-1424-4d43-af4e-49ece0855f55</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Devika_Mehra_PhD_kappa.pdf">https://portal.research.lu.se/files/3154017/4067571.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1152470</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Sexual behaviour</topic> <topic>alcohol</topic> <topic>university students</topic> <topic>condom</topic> <topic>contraception</topic> <topic>sexual coercion</topic> <topic>academic performance</topic> <topic>Uganda</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-86-4</identifier> <identifier type="oldLupId">4064578</identifier> <part> <detail type="volume"> <number>2013:113</number> </detail> <extent unit="pages"> <total>158</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.globalhealthaction.net/index.php/gha/article/view/18599</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-10-25T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>480d8887-1424-4d43-af4e-49ece0855f55</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-27T11:07:47Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:31+02:00</recordDateApproved> </recordInfo> </mods>

Focus is on memory as a social phenomenon and culture-specific resource created by these deliberate practices. The culture-specific element is oral culture. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Place is an important part of the contextualization of social memory. The pre-Christian and early Christian farm has a special quality that is so self-evident that it is seldom highligh¬ted - the presence of the graves within its territory. This distinguishes that farm from those where the dead were buried in a graveyard. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; My theoretical framework is that of memory theory. In focus is human agency, formal and ritualized practice, and structured and constructed reality. All the media then available for memory construction are taken into consideration: formal and ritual acts such as ‘super-imposing’; material remains such as graves and buildings; sites on different scale levels in the landscape, such as farms with grave-fields and yards; narratives such as the Icelandic sagas. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The source material consists of more than 300 archaeological excavations of grave-fields and settlements conducted in the Mälaren valley. The analysis include four sub-studies of superimpositions: grave on grave, house on house, grave on house, and house on grave. It takes into account possible variations in the scope and expression of the superimpositions because of the chronological, geographical, and social context. One of the more significant results is that the superimpositions showed very deliberate patterns, implying that the practices were very conscious. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the synthesis superimposition practices are considered as historical entities, and as functions of a possible historical culture in different eras. Down the ages, from the Migration Period up to and including the early Middle Ages, major regional changes in society have steered the contemporaneous perceptions of history. This means new social, ideological, and cultural context, which in its turn created the need for new memories.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; I vår egen tid finns ett stort intresse för släktforskning och historia hos många. Men man tänker sällan på att även människor i gångna tider kunnat blicka tillbaka på sitt förflutna och fundera på sin egen plats i släktleden. Vad var de ville minnas och hur mindes de i en tid utan skriv- och läskunnighet? Det är frågor som ställs i avhandlingen och där svaren söks i de lämningar som grävts fram från järnåldern vid många arkeologiska undersökningar i Mälardalen. En inblick i detta ger oss en större förståelse för det förflutnas roll och betydelse i såväl dåtid som vår egen tid. I avhandlingen visas hur människor på gårdar under järnåldern i Mälardalen ”byggde” minnen genom att medvetet placera nya gravar och hus på tidigare generationers gravar och hus.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/38bddaf4-70bd-4271-a75d-d6caf66eb751</url> </location> </relatedItem> <originInfo> <publisher>Nordic Academic Press</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>archaeology</topic> <topic>memory</topic> <topic>historical culture</topic> <topic>ritual</topic> <topic>practice</topic> <topic>superimpositions</topic> <topic>the past in the past</topic> <topic>Mälaren region</topic> <topic>house</topic> <topic>grave</topic> <topic>Migration Period</topic> <topic>Viking Age</topic> <topic>early Middle Age</topic> </subject> <subject authority="lup"> <topic>History and Archaeology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Vägar till Midgård</title> </titleInfo> <identifier type="issn">1650-5905</identifier> <identifier type="isbn">978-91-89116-99-3</identifier> <identifier type="oldLupId">3449472</identifier> <part> <detail type="volume"> <number>15</number> </detail> <extent unit="pages"> <total>325</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-04-12T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>38bddaf4-70bd-4271-a75d-d6caf66eb751</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:31+02:00</recordDateApproved> </recordInfo> </mods>

Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion concepts is Partially Premixed Combustion (PPC). PPC is aimed to provide combustion with low smoke and NOx without sacrificing fuel consumption. This thesis presents the development of a multi-cylinder PPC concept. It reaches from the basic characterization of this new combustion strategy to the demands on hardware, control and fuels for a realizable PPC solution. In summary it contains a thorough PPC characterization where the results suggest that high EGR, early injection PPC strategies are to prefer over late injection approaches or smokeless rich diesel combustion. Further, a strong connection between mixing period, defined as the period between end of injection and start of combustion, and PPC has been ascertained. Based on this knowledge a combustion controller with feedback control of mixing period was derived. The operating range of multi-cylinder diesel PPC was then evaluated. The study showed that the PPC load range was limited covering only 25% of the operating region for conventional combustion. In order to reach higher loads for PPC the EGR system was rebuilt to a low pressure system. This system improves EGR/air mixing and cooling and enables high EGR and boost pressure simultaneously. Additionally, gasoline fuels were introduced to extend the ignition delay and mitigate soot formation. An extensive fuel comparison was carried out to find the most suitable fuel for PPC operation. With the improved set-up the operating range was reevaluated. By combining the use of a low pressure EGR system and standard gasoline the operating region of PPC has been extended to cover 50% of the engine nominal operating region. The final part of this thesis is dedicated to a novel method of cylinder individual efficiency estimation based on the cylinder pressure trace. With this method, control strategies aiming directly at fuel consumption optimization can be developed. An extremum seeking control algorithm was applied. The results show that the controller manages to find the maximum brake torque region both with and without external excitation. Finally, the estimation error in accumulated fuel consumption from the experiments is around 1% which shows the potential of using the absolute value of the efficiency estimation in other control concepts.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Kraven på bränslesnåla och rena motorer har ökat under de senaste åren. Det började med att priset på olja steg kraftigt i början av 2000-talet. Kraven växte sedan ytterligare i kölvattnet av debatten kring växthuseffekten där koldioxid, en av de dominerande produkterna vid förbränning, spelar huvudrollen. Med tanke på att sänkt bränsleförbrukning rör både ekonomiska och miljömässiga intressen så kommer forskning kring ämnet att fortsätta vara högintressant inom överskådlig framtid. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Bilindustrin har traditionellt varit dominerad av ottomotorn som i kombination med trevägskatalysatorn har ansetts vara ett miljövänligt motoralternativ med mycket låga utsläpp av giftiga förbränningsprodukter. Lastbilsindustrin å andra sidan har sedan länge dominerats av dieselmotorer av en andledning, den lägre bränsleförbrukningen. Den spelar naturligtvis stor roll inom transportindustrin där små sänkningar i bränsleförbrukning betyder stora besparingar över tiden. På grund av den lägre förbrukningen har nu även andelen personbilar utrustade med dieselmotorer ökat kraftigt, framförallt i Europa. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det finns dock ett problem med dieselmotorn, utsläppen av kväveoxider och rök. På grund av att dieselmotorn kräver ett överskott av luft i cylindern vid förbränningen så kan en trevägskatalysator inte användas då den inte fungerar med luftöverskott. För att sänka dieselmotorns utsläpp används idag istället mer komplicerade efterbehandlingssystem som SCR för att sänka kväveoxider och partikelfilter för att minska röken. Dessa system är relativt dyra och det finns ett stort intresse för att kunna klara sig utan åtminstone ett av efterbehandlingssystemen utan att kompromissa med utsläppsnivåerna. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att lösa detta problem gäller det att angripa själva kärnan, förbränningen i cylindern. Hela tiden studeras och testas framtida förbränningskoncept världen över på universitet, forskningsinstitut och inom industrin. Ett av de mest lovande och uppmärksammade förbränningskoncepten kallas partiellt förblandad förbränning eller på engelska: Partially Premixed Combustion (PPC). Det är forskning kring detta förbränningskoncept som den här avhandlingen fokuserar på. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; PPC bygger på att man, genom att återcirkulera kylda avgaser (EGR) till motorn, kan sänka förbränningstemperaturen och på så vis också bildningen av kväveoxider. Röken undertrycks genom en förlängning av tändfördröjningen så att diesel och luft blandas innan förbränningen startar. Det är denna princip som gett förbränningskonceptet dess namn. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den första delen av avhandlingen handlar om att kartlägga när och hur diesel-PPC uppkommer. Kopplingar mellan dieselinsprutningens tidpunkt i kombination med EGR-halten görs till tändfördröjning och förbränningens karaktär. Genom detta fastställs vilken typ av förbränning och förbränningsstyrning som är mest lämplig ur både verkningsgrads- och utsläppsperspektiv. Kunskapen användes för att utveckla en reglerstrategi som säkerställer PPC-förbränning när det är möjligt. Denna styrning åstadkoms genom återkoppling av en parameter kopplad till tiden mellan insprutning och förbränningsstart vilken i sin tur används för att automatiskt styra insprutningstidpunkten. Den framtagna regulatorn upprätthåller PPC-förbränning under både last och varvtalsändringar oberoende av yttre störningar. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Följande fas är en undersökning av det praktiska driftssområdet för PPC i en flercylindrig motor. Det visar sig att PPC bara fungerar på låga laster och att driftsområdet endast täcker 25% av motorns nominella driftsområde. Genom undersökningen kan ett antal begränsande faktorer identifieras. Fördelningen av EGR skiljer mellan cylindrarna vilket gör att en cylinder riskerar hög rökbildning samtidigt som en annan har hög kväveoxidbildning. Detta komplicerar optimeringen. Temperaturen i insugssystemet är betydligt högre än önskat på grund av underdimensionerad EGR-kylare. Ytterligare förlängning av tändfördröjningen är önskvärd då rökbildningen är den begränsande faktorn för PPC i denna studie. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att lösa ovanstående problem görs följande; Motorns EGR-system modifieras för att förbättra EGR/luft-blandningen samt öka kylkapaciteten. Vidare introduceras nya bränslen med högre oktantal vilket förlänger tändfördröjningen. För att konstatera vilken typ av bränsle som är mest lämpat för PPC görs en omfattande undersökning mellan diesel, låg- och högoktanig bensin där verkningsgrad, utsläpp och förbränningsstabilitet jämförs. Resultatet är att den ökade tändfördröjningen med högoktanig bensin minskar rökutsläppen drastiskt utan att kompromissa med kväveoxidutsläppen. Denna minskning kommer dock på bekostnad av försämrad förbränningsstabilitet på lägre laster. Baserat på resultatet i denna undersökning görs sedan en ny utvärdering av PPCs driftsområde där den maximala lasten nu ökas till 70% av dieselmotorns maxlast på lägre varvtal. Sammantaget så täcker PPC-konceptet nu 50% av motorns nominella driftsområde. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den avslutande delen av avhandlingen behandlar en metod att skatta verkningsgraden i motorn cylinderindividuellt för att kunna använda reglerstrategier som optimerar förbränningen och sänker bränsleförbrukningen under drift. Metoden, som baseras på tryckmätningar från cylindrarna, är den första i sitt slag och den öppnar upp för många nya typer av motorreglering både gällande optimering under stationär drift och under varierande last och varvtal. Metoden är användbar för både konventionell dieselförbränning och PPC.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f072a909-5dda-44b3-844a-8d21fdeae898</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="ThesisPrintV3.pdf">https://portal.research.lu.se/files/3154249/1969918.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3095827</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Efficiency estimation</topic> <topic>Closed-loop control</topic> <topic>EGR</topic> <topic>Diesel engine</topic> <topic>Partially Premixed Combustion</topic> <topic>Combustion control</topic> </subject> <subject authority="lup"> <topic>Energy Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-148-4</identifier> <identifier type="oldLupId">1969911</identifier> <part> <extent unit="pages"> <total>166</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-08-19T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>f072a909-5dda-44b3-844a-8d21fdeae898</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:33+02:00</recordDateApproved> </recordInfo> </mods>

The students had a mean age of 23.8 years, and 64% were male. The results from this baseline assessment show that the mean AUDIT score (± sd) was 10.3 ± 5.2 for males and 8.1 ± 4.7 for females. AUDIT stands for Alcohol Use Disorders Identification Test and is used world-wide to assess alcohol habits. Scores equal to or above eight for males, and equal to or above four for females indicate an at-risk drinking pattern. It was shown that AUDIT scores were correlated with high levels of Distance and Expressiveness in the social climate of the residence halls, assessed by the students themselves. &lt;br/&gt;&lt;br&gt; The students were cluster randomised (with the residence hall as the cluster unit) into three groups. One group received a three hour cognitive-based harm reduction education (called BSTP), and one group received a three hour lecture by therapists trained in twelve-step philosophy (called TSI). The third group did not receive any intervention. The students were then monitored for three years. All students answering the questionnaires received a short personalized feedback, independently of randomisation group. The two-year assessment showed that all groups had reduced their AUDIT scores. When assessing only those who belonged to the at-risk drinking group, the students in the BSTP group reduced their AUDIT scores significantly more than the students in the control group (a reduction of 3.9 and 2.8 points, respectively, p&amp;lt;0.05). There was no significant difference between the TSI group and the BSTP or control group, with a reduction in the TSI group of 3.0 points. Furthermore it could be seen that more students participated in the BSTP education than in the TSI lecture (63% versus 25%, p&amp;lt;0.001).&lt;br/&gt;&lt;br&gt; Using trajectory analyses on all assessment points, five different trajectory groups could be identified with AUDIT. All slopes showed reduction of AUDIT scores over time. No women could be found in the highest AUDIT trajectory group, which also included younger persons.&lt;br/&gt;&lt;br&gt; The students were also compared with students in other parts of Sweden and in the US, and similar moderators of drinking patterns could be found, although country was of importance.&lt;br/&gt;&lt;br&gt; To conclude, in mean all students reduced their drinking over time. This reduction could be further reduced by participation in a harm reduction education for the students having an at-risk drinking pattern. The social climate of the residence halls and the students’ drinking habits are correlated, as are the students’ country of residence.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/83d753db-0b84-41b6-9971-52fe9a02456e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Henriettae_Avhandling_080429.pdf">https://portal.research.lu.se/files/3154350/1149770.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">815425</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>alcohol</topic> <topic>residence halls</topic> <topic>intervention</topic> <topic>cluster randomised controlled trial</topic> <topic>social climate</topic> <topic>trajectories</topic> <topic>cultural influence</topic> <topic>AUDIT</topic> <topic>Students</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-15-6</identifier> <identifier type="oldLupId">1149769</identifier> <part> <detail type="volume"> <number>2008:62</number> </detail> <extent unit="pages"> <total>117</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-31T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>83d753db-0b84-41b6-9971-52fe9a02456e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-17T07:43:44Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:35+02:00</recordDateApproved> </recordInfo> </mods>

They can further profit from this by getting their ongoing connection moved from the current system to another. The main issues are to make this move without losing the ongoing connection and to make it seamless, i.e., without the user noticing it. This action of moving an ongoing connection between different wireless systems is called inter-system handover. To make the inter-system handover the mobile terminal in use must support both the involved systems. By using the mobile terminals possibility to change system, the user can increase, e.g., the coverage, the bandwidth and the capacity. When using inter-system handovers the cost of the connection can also be optimized depending on the actual cost of using a specific system. Since the user in advance can choose the settings of the involved parameters, a specific operator or wireless system could be given priority when several alternatives exist.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To easier identify and understand the handover procedure it has been categorized and divided into classes. This new handover terminology structure is presented in one section of the thesis. The different types of handovers are divided into classes and presented with a short description. For example, one class is called initiation. Within this class the handovers are then categorized as network initiated, i.e., the network initiates the handover, and mobile initiated which indicates that the mobile initiated the handover.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Further, several investigations on wireless hierarchical structures are presented. The focus is on the inter-system handovers made between the different levels. Hierarchical structures with both two and three levels of wireless systems have been analyzed. They are performed to understand how the results change when a smaller area is compared with a larger that supports more types of wireless systems. The investigations are made with different parameter settings to obtain a more thorough base for conclusions. The results obtained in this thesis are very useful both from the view of a user and from an operators point of view. They would be beneficial when the user should set his parameters and/or for the operator planning the networks and their individual architectures.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a5b02ff1-b023-40fc-9dc7-db5ae880ff5b</url> </location> </relatedItem> <originInfo> <publisher>Electrical and Information Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>hierarchical structure</topic> <topic>performance analysis</topic> <topic>inter-system handover</topic> <topic>wireless systems</topic> <topic>handover terminology</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">940133</identifier> <part> <extent unit="pages"> <total>142</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-02-14T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>a5b02ff1-b023-40fc-9dc7-db5ae880ff5b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-12-05T13:30:59Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:39+02:00</recordDateApproved> </recordInfo> </mods>

In this thesis we will present different experiments, supported by theory, where attosecond EWPs are created in presence of a strong infrared (IR) field. By tuning the central frequency of the attosecond pulses and/or changing the target gas, the initial energy of the wave packets is set to be either above, or below the ionization potential.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In a first set of experiments, trains of free attosecond EWPs separated by half a laser period are created by single photon ionization. Depending on the timing of ionization compared to the external IR field, a shear and/or a phase difference between the consecutive EWPs is induced. Because the EWPs are created coherently, interferences depending on their phase difference will occur. The analysis of the interferograms enables to retrieve information about the phase of the EWPs.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In a second set of experiments, bound electron wave packets are created below the ionization potential of a target gas. In the case of a train of bound EWPs, we find that the ionization is greatly enhanced by the presence of the infrared laser field and that this enhancement strongly depends on the timing between the attosecond pulses and the laser field. We show that this effect can be attributed to interference between consecutive wave packets. In the case of a single bound EWP, we are able to probe its time evolution with a short IR pulse.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/11588ed0-096f-4369-bd4c-f1c88f784d78</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis_TR.pdf">https://portal.research.lu.se/files/3154853/1043567.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">27486922</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Attosecond Bound Electron Wave Packet Dynamics</topic> <topic>Attosecond Pulse Train</topic> <topic>High-Order Harmonics</topic> <topic>Electron Wave Packet Interferometry</topic> <topic>Attosecond Physics</topic> </subject> <subject authority="lup"> <topic>Atom and Molecular Physics and Optics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Reports on Atomic Physics</title> </titleInfo> <identifier type="issn">0281-2762</identifier> <identifier type="oldLupId">1043561</identifier> <part> <detail type="volume"> <number>LRAP-390</number> </detail> <extent unit="pages"> <total>142</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-03-28T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>11588ed0-096f-4369-bd4c-f1c88f784d78</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:40+02:00</recordDateApproved> </recordInfo> </mods>

These ions can be naturally trapped inside host crystals, and with the phonon vibrations removed by cooling down to cryogenic temperatures (&amp;lt; 4 K), they can be used for a number of different quantum information processes. Most experiments were carried out using PrYSO, but also other crystal types were investigated, such as Nd:YVO4, and La2(WO4)3. The characterization of the ions were done with a variety of methods, including among others, photon echo techniques and electromagnetically induced transparency.&lt;br/&gt;&lt;br&gt; Quantum computing is a rapidly growing field and there are still many potential candidates for its implementation. In our work we have utilized the spin states of the Pr rare-earth ion as a qubit, and demonstrated arbitrary single qubit gates, which are important pieces towards a quantum computing realization in these systems. Most of the experimental work done for the thesis was carried out using an ensemble approach, that has the advantage of giving a strong readout signal, but for future scaling to multiple qubits, single instances are more promising, which is discussed.&lt;br/&gt;&lt;br&gt; Quantum memories are crucial components in applications such as quantum networks and long distance quantum communication. In this thesis, work has been done to investigate how quantum memories can be implemented in rare-earth crystals. In particular, there are two protocols, CRIB and AFC, which were suggested with rare-earth crystals directly in mind, and both of these require high optical depth, for maximum recall efficiency. In this thesis, implications of being in the high optical depth regime, with phenomena such as superradiance, a collective effect that could cause the stored light to be immediately reemitted, and slow light effects that come from performing the storage inside spectrally structured materials, were investigated.&lt;br/&gt;&lt;br&gt; In order to carry out the phase-sensitive experiments, a laser system with a very narrow linewidth of ~1 kHz at 606 nm was constructed, by locking the laser to a semi-persistent spectral hole. In addition, many experiments required advanced pulse shapes, such as complex sechyp pulses or pulses obtained from optimal control theory. In order to be able to accurately create such shapes, an elaborate system using an arbitrary waveform generator and two well calibrated AOMs, controlled from a computer, was also built.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Målet avhandlingen har varit att undersöka möjligheten att bygga en kvantdator i kristaller dopade med joner av sällsynta jordartsmetaller. Det har visat sig att sådana joner har en väldigt lång livstid, vilket är en förutsättning för de typer av experiment som har utförts i den här avhandlingen. För att ytterliggare förhindra att de känsliga tillstånden i jonerna störs, så har kristallerna kylts ner till ungefär -271 grader C (bara 2 grader över absoluta nollpunkten), med hjälp av en kryostat som använder flytande helium. Innan experimenten kunde påbörjas, var det även nödvändigt att bygga en laser med en väldigt stabil frekvens (färg på ljuset). Man kan säga att, för att kvantdatorexperimenten skulle lyckas var det tvunget att hålla frekensen hos lasern stabil ner till 12:e decimalen, vilket kräver en väldigt hög grad av kontroll på lasersystemet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En kvantdator är en slags dator som är begränsad endast av de kvantmekaniska spelreglerna, vilket betyder att den löser uppgifter på ett helt annat sätt än en klassisk dator, och därför har potential att bli mycket kraftfullare. Den minsta informationsenheten i en klassisk dator är en bit, vilken kan vara antingen 1 eller 0. En motsvarande kvantbit kan också vara 1 eller 0, men med den skillnaden att den kan, med en viss sannolikhet, också vara i båda tillstånden samtidigt! Detta är ett så kallat superpositionstillstånd, och med hjälp av dessa kan man få en kvantdator att lösa vissa typer av uppgifter på flera olika sätt samtidigt. Detta är en av de egenskaper som gör den potentiellt kraftfullare än en vanlig klassisk dator.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Kvantdatorfältet är fortfarande ungt. Ingen har lyckats få mer än några få kvantbitar att samverka, och det finns en mängd olösta frågor angående hur man kan skala upp det till att innehålla så många kvantbitar att den kan börja lösa stora problem. Det är därför fortfarande viktigt att ständigt söka efter nya möjligheter, och nya sätt att bygga kvantbitarna på, så att något sätt i framtiden lyckas bli skalbart. I våra experiment har vi lyckats visa att joner från de sällsynta jordartsmetallerna kan erbjuda sådana intressanta möjligheter. Vi visade detta genom att fullständigt karatärisera en kvantbit i en sådan jon, där enskilda elektrontillstånd används som 1 eller 0. Vi visade även att man med hjälp av noggrant kalibrerade ljuspulser från den stabiliserade lasern, kan utföra grindoperationer på kvantbiten, som t. ex. NOT-grinden, men vi utförde även mer avancerade grindar som endast finns i en kvantdator.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; På vägen mot realiserandet av en kvantdator har även ett antal andra koherenta processer, som också bygger på de kvantmekaniska reglerna, stötts på. Dessa innefattar bland annat så kallad superradians, vilket är en process där många atomer samverkar kvantmekaniskt på ett sådant sätt att när atomerna skickar ut ljus (deexciteras) så gör de det mycket snabbare än atomerna skulle ha gjort om de hade varit ensamma. Andra intressanta fenomen som påträffades var långsamt och snabbt ljus. Genom att manipulera atomer med olika frekvens på olika sätt kan man nämligen skapa förhållanden där en ljuspuls som skickas genom materialet går mycket långsammare eller mycket snabbare än den vanliga ljushastigheten. Under tillräckligt extrema förhållanden kan man till och med få toppen på en ljuspuls att komma ut ur materialet innan den ens har kommit in! Detta innebär inte ett brott mot relativitetsteorin eller mot kausaliteten, utan betyder istället att man måste vara noggrann med hur man definierar informationsinnehållet i en puls.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f204f6d2-a5a6-419f-8eef-6d58eaccec25</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Walther2009_kappa.pdf">https://portal.research.lu.se/files/3155229/2302413.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8868719</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Physics, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>quantum memories</topic> <topic>laser stabilization</topic> <topic>quantum computation</topic> <topic>rare-earth-ion-doped crystals</topic> <topic>spectral hole-burning</topic> <topic>superradiance</topic> <topic>entanglement</topic> <topic>spectroscopy</topic> <topic>slow light</topic> </subject> <subject authority="lup"> <topic>Atom and Molecular Physics and Optics</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-628-7718-7</identifier> <identifier type="oldLupId">1300770</identifier> <part> <extent unit="pages"> <total>193</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-03-20T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>f204f6d2-a5a6-419f-8eef-6d58eaccec25</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:05:48+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:05:48+02:00</recordDateApproved> </recordInfo> </mods>

Despite advancements in the management of CRC, mortality remains high. Accumulating evidence indicates that CRC is a heterogeneous disease, which affects outcome beyond what can be predicted by disease stage and other conventional prognostic factors. Thus, there is a great need to identify new biomarkers to enable a more accurate prognostication, and to help select patients for adjuvant treatment.&lt;br/&gt;&lt;br&gt; The aim of this thesis was to investigate the associations of a series of putative biomarkers with survival, treatment response and clinicopathological factors in a large cohort of incident CRC, with special attention to sex differences.&lt;br/&gt;&lt;br&gt; The study group consisted of tumours from 557 incident cases of CRC in the Malmö Diet and Cancer Study (MDCS). The tumours, assembled in tissue microarrays, were evaluated for expression of cyclin D1, mismatch repair proteins, beta-catenin and epidermal growth factor receptor (EGFR) by immunohistochemistry, and further, EGFR gene copy number (GCN) alterations by brightfield double-in situ hybridization. In addition, KRAS and BRAF mutational status was assessed by pyrosequencing. Associations with clinicopathological and investigative factors were explored by Chi Square and Spearman’s correlation tests, and Kaplan-Meier analysis and Cox proportional hazards modelling were applied for survival analysis.&lt;br/&gt;&lt;br&gt; We hereby found that nuclear cyclin D1 expression was associated with female sex and a favorable prognosis, although not independently, in male, but not in female, CRC. Microsatellite instability (MSI) correlated to distinctive clinicopathological features, cyclin D1 expression, and independently predicted a good prognosis in stage III-IV CRC. Moreover, beta-catenin overexpression correlated independently with a prolonged survival from stage III-IV CRC, and was associated with microsatellite stable (MSS) tumours. We also observed that KRAS codon 13 mutation predicted a poor prognosis in female CRC, but not independently of established prognostic factors. KRAS and BRAF mutations were mutually exclusive, and correlated with MSS and MSI, respectively. BRAF mutation was independently associated with a reduced survival in male patients with MSS CRC. Furthermore, both EGFR protein expression and GCN alterations were associated with a reduced survival in stage III-IV CRC, the latter, however, not independently of established prognostic factors. EGFR protein expression correlated significantly with EGFR GCN alterations, although a substantial proportion of EGFR expressing tumours displayed a normal GCN, and vice versa. Finally, EGFR alterations were significantly associated with a reduced survival in curatively treated patients with stage III-IV disease receiving adjuvant oxaliplatin.&lt;br/&gt;&lt;br&gt; In conclusion, the results from this thesis demonstrate several relevant associations of the investigative biomarkers with prognosis and treatment response in CRC. Moreover, substantial sex differences in the clinicopathological correlates and prognostic significance of some of the biomarkers were observed.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ceeeff07-e799-4014-bb85-6d247ba62035</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa.pdf">https://portal.research.lu.se/files/3155504/4139778.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2194910</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Pathology, (Lund)</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>colorectal cancer</topic> <topic>prognosis</topic> <topic>treatment prediction</topic> <topic>biomarkers</topic> <topic>sex differences</topic> <topic>cyclin D1</topic> <topic>microsatellite instability</topic> <topic>beta-catenin</topic> <topic>KRAS mutation</topic> <topic>BRAF mutation</topic> <topic>EGFR expression</topic> <topic>EGFR gene copy number alterations</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-92-5</identifier> <identifier type="oldLupId">4139527</identifier> <part> <detail type="volume"> <number>2013:119</number> </detail> <extent unit="pages"> <total>86</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-11-22T09:15:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The aim of the thesis was to investigate short and long term cardiac effects after fetal exposure to DM, investigate the ability of a 5 minute Apgar score as a marker for obstetrical care, investigate the association between mode of delivery in diabetic pregnancies and a low 5 minute Apgar score, and to investigate the association between offspring birth weight and maternal risk of future DM. &lt;br/&gt;&lt;br&gt; Paper 1: Fetuses to mothers with either type 1 DM (p = 0.0015) and gestational diabetes mellitus (GDM) (p = 0.006) showed increased pulsatility index in the ductus venosus (PI-DV) in relation to gestational age. After the exclusion of SGA fetuses and those with blood flow changes, the PI-DV was still increased in type 1 DM (p = 0.02) and GDM pregnancies (p = 0.035), presumably reflecting short term cardiac impact.&lt;br/&gt;&lt;br&gt; Paper 2: Fetuses exposed to type 1 DM showed an increased risk of future cardiovascular disease, as measured by consumption of drugs for cardiovascular disease, OR 1.46 (95% CI 1.16-1.83), this increased risk was however no longer present when data was adjusted for offspring with insulin dependent DM, OR 1.22 (95% CI 0.97-1.54). As previous studies have showed, an increased risk of future cardiovascular disease was found when born SGA, OR 1.29 (95% CI 1.24-1.35). No increased risk was found after being born LGA.&lt;br/&gt;&lt;br&gt; Paper 3: The Apgar score is a resourceful marker of obstetrical care, as a substantial risk increase of needing education in special schools, OR =1.93(95% CI 1.75-2.14) low, or no grades when graduating from compulsory school, in nearly all school subjects, was found after being born with a 5 minute Apgar score under 7. One of 44 children born with an Apgar-score &amp;lt;7 at 5 minutes after birth will need education in a special school due to the factors leading to the low Apgar score.&lt;br/&gt;&lt;br&gt; Paper 4: A 50% decreased risk of an Apgar score&amp;lt;7 at 5 minutes was found in DM+GDM pregnancies after a planned CS in gestational week 38 as compared to planned vaginal birth (from gestational week 39 and beyond), (p= 0.021), but no decreased risk was found in the DM group (p=0.08), GDM group (p=0.12) or LGA group alone (p=0.06).&lt;br/&gt;&lt;br&gt; Paper 5: Offspring birth weight is a direct mirror of the maternal metabolic status, as a profound risk increase of developing both type 1 OR=3.46 (95% CI 3.12-3.83) or type 2 DM OR= 2.90 (95% CI 2.80-3.01) was found subsequent to giving birth to a LGA or macrosomic fetus.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; barnet. Förekomsten av graviditetsdiabetes ökar stadigt, främst pga. ökad vikt hos mamman. Syftet med min avhandling var att undersöka både den kort och långsiktiga risken för hjärtpåverkan hos avkomman till kvinnor med diabetes under graviditeten, undersöka om Apgar-poäng kan användas som mått på förlossningsvården, samt jämföra Apgar-poäng hos nyfödda beroende på om mamman förlösts med planerat kejsarsnitt eller vaginal förlossning, och till sist undersöka mammans framtida risk för diabetes efter det att hon fött ett stort barn.&lt;br/&gt;&lt;br&gt; Avhandlingen innefattade följande fem studier:&lt;br/&gt;&lt;br&gt; Delarbete 1: Blodflödet i duktus venosus hos foster till kvinnor med diabetes&lt;br/&gt;&lt;br&gt; Hjärtmissbildningar är betydligt vanligare hos barn till mödrar med diabetes under graviditeten, och förekommer hos 3-6%. Mätningar av blodflödet i kärlet som leder blodet till fosterhjärtat, duktus venosus (DV), anses återspegla fostrets hjärtfunktion och avvikande flöde med ökat pulsatilt index (PI) har uppmätts hos foster med hjärtmissbildningar, kromosomavvikelser, och hos foster med förhöjd nivå av hjärtsviktsmarkören pro-BNP. &lt;br/&gt;&lt;br&gt; Blodflödesundersökningar av fostercirkulationen erbjuds till alla högriskgraviditeter, inklusive diabetiker. Vi har funnit en ökad risk för förhöjt PI-DV hos foster till gravida diabetiker i jämförelse med en frisk normal population, vilket skulle kunna tala för en påverkan på hjärtat. Vidare har vi visat ett samband mellan moderns långtidsblodsocker, HbA1c, och PI-DV. &lt;br/&gt;&lt;br&gt; Delarbete 2: Diabetes under graviditeten och avkommans framtida risk för hjärtkärlsjukdom&lt;br/&gt;&lt;br&gt; Hypotesen om &quot;fetal origins&quot; hävdar att nutritionella förhållanden i livmodern programmerar fostrets mottaglighet för kroniska sjukdomar som vuxen. Teorin grundar sig på epidemiologiska data som visar ett samband mellan låg födelsevikt och hjärtkärlsjukdom i vuxen ålder. Senare forskning har även visat att hög födelsevikt ökar risken för framtida hjärtkärlsjukdom. Diabetes under graviditeten medför en rubbad ämnesomsättning och en ökad tillgång på näring till fostret, och avkomman är ofta stora.&lt;br/&gt;&lt;br&gt; Genom att samköra information från Medicinska Födelse Registret (MFR) med information från Läkemedelsregistret, har vi jämfört risken för uttag av blodtrycks och hjärtläkemedel som vuxen hos de som exponerats för mammans diabetes under fosterlivet med de som inte exponerats för diabetes under fosterlivet. &lt;br/&gt;&lt;br&gt; Studien innefattade 1 551 603 personer, och visade en ökad risk för uttag av blodtrycks och hjärtläkemedel hos den vuxna avkomman till mammor som hade diabetes under graviditeten. Typ 1 diabetes är dock ärftligt, och typ 1 diabetiker har även en ökad risk för högt blodtryck och hjärtkärlsjukdom. Efter att resultaten justerades för avkomma som själva hade diabetes, kunde inte den ökade risken för hjärtkärlsjukdom hos avkomman påvisas längre. Vi tolkar därför resultaten att det är avkommans egna diabetes snarare än exponeringen för mammans diabetes i fosterlivet som utgör risken för hjärtkärlsjukdom.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Delarbete 3: Relationen mellan låg 5 minuters Agpar-poäng och framtida skolprestation&lt;br/&gt;&lt;br&gt; Apgar-poäng mäts vid 1, 5 och 10 minuters ålder på förlossningskliniker världen över för att kliniskt värdera det nyfödda barnet. Låg Apgar-poäng vid 5 minuter är associerat med ökad risk för cerebral pares, epilepsi och utvecklingsstörningar. Det långsiktiga prognostiska värdet av ett lågt Apgar-poäng är dock ifrågasatt och vi har velat undersöka hur bra Apgar-poäng är som markör för att utvärdera förlossningsvården. Sambandet mellan låg 5 minuters Apgar-poäng och långsiktig kognitiv påverkan har analyserats, genom att titta på associationen mellan Apgar-poäng och avgångsbetyg från grundskolan (ca 900 000 personer) vid 16 års ålder. Data från MFR har samkörts med Skolbetygsregistret. Genom att även samköra med utbildningsregistret har vi kunnat justera för mammans utbildningsnivå. Våra resultat visar att de barn som hade Apgar-poäng &amp;lt;7 vid 5 minuter har en ökad risk att hamna i särskola, ett av 44 barn som föds med Apgar-poäng &amp;lt;7 vid 5 minuter kommer att kräva skolgång i särskola. Vidare har vi visat att det finns ett rakt samband mellan ett stegs sänkning av Apgar- poäng och skolgång i särskola. Vi har även visat att de barn som hade Apgar-poäng &amp;lt;7 vid 5 minuter barn hade ökad risk att få lägsta möjliga avgångsbetyg samt minskad chans att få högsta möjliga avgångsbetyg från 9:an.&lt;br/&gt;&lt;br&gt; Delarbete 4: Jämförelse av Apgar-poäng hos nyfödda till diabetiker efter planerat kejsarsnitt eller planerad vaginal förlossning &lt;br/&gt;&lt;br&gt; Foster till mammor med diabetes under graviditen löper större risk att utsättas för syrebrist, få andningsstörningar samt blodsockerfall i samband med förlossningen. Nyfödda barn till diabetesmödrar har dessutom ofta hög födelsevikt, och som följd av detta lider de oftare av skador. &lt;br/&gt;&lt;br&gt; De svenska rekommendationerna eftersträvar att gravida diabetiker ska genomgå en vaginal förlossning i fullgången tid. Trots rekom-mendationerna, är det förvånansvärt många kvinnor som genomgår ett akut kejsarsnitt eller förlossning med sugklocka eller tång. Vi har visat på en ca 50 % lägre risk att födas med Apgar-poäng &amp;lt;7 vid 5 minuter hos diabetiker som genomgår ett planerat kejsarsnitt i jämförelse med de som påbörjar en vaginal förlossning. Det krävs dock 132 planerade kejsarsnitt hos diabetiker för att undvika att ett barn föds med Apgar-poäng &amp;lt;7 vid 5 minuter, och därför är det inte självklart att ett planerat kejsarsnitt bör erbjudas till alla diabetiker.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Delarbete 5: Sambandet mellan fostrets födelsevikt och mammans framtida risk för diabetes&lt;br/&gt;&lt;br&gt; Risken för framtida typ 2-diabetes hos kvinnor som har drabbats av graviditetsdiabetes vid en tidigare graviditet är välkänd och varierar mellan 2-70% beroende på uppföljningstiden. Det råder ingen konsensus hur diagnosen graviditetsdiabetes ska ställas, och man har även observerat ökade komplikationer hos såväl fostret och kvinnan själv, hos de kvinnor som ligger precis under den diagnostiska gränsen för graviditetsdiabetes.&lt;br/&gt;&lt;br&gt; Både kvinnor som är överviktiga och som har diabetes är kända för att föda stora barn, pga. av insulinresistens och ökad näringstillgång till fostret. Samma kvinnor löper framtida risk att få typ 2-diabetes.&lt;br/&gt;&lt;br&gt; Genom att samköra information från MFR och Diabetesregistret har vi undersökt sambandet mellan avkommans födelsevikt och mammans framtida risk att få diabetes, hos kvinnor som inte hade graviditetsdiabetes. Vi har funnit en ca 3.5 gånger ökad risk att få typ 1 diabetes och 2.9 gånger ökad risk att få typ 2 diabetes efter det att kvinnan fött ett stort barn. Efter att kvinnan fött ett stort barn, är risken ca 9 gånger högre att få typ 1 diabetes och 11 gånger högre att få typ 2 diabetes inom ett år efter förlossningen, jämnfört med de kvinnor som föder normalstora barn.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c680a4de-1ee5-4886-b424-20df337cde78</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa.pdf">https://portal.research.lu.se/files/3156226/3173814.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2594705</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Obstetrics and Gynecology, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Gynaecology, Obstetrics and Reproductive Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-60-9</identifier> <identifier type="oldLupId">3167732</identifier> <part> <detail type="volume"> <number>2012:97</number> </detail> <extent unit="pages"> <total>168</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-12-07T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>c680a4de-1ee5-4886-b424-20df337cde78</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:06+02:00</recordDateApproved> </recordInfo> </mods>

It is caused by a mutation in a gene called huntingtin. HD is a so-called neurodegenerative disease, where there is a loss of neurons in areas of the brain that control body movements. This results in uncontrolled dance-like movements (chorea). Traditionally, research on HD has focused round the brain and what is causing the neurodegeneration. There are however other symptoms that cannot be overlooked. Patients are suffering from weight loss despite adequate intake of nutrition. They also suffer from muscle wasting, cognitive deterioration, psychiatric problems, sleep disturbances, cardiac failure and a subtle increase in inflammatory proteins. These symptoms further affect the quality of life and disease progression for patients with HD. &lt;br/&gt;&lt;br&gt; The overall aim of this thesis was to investigate the mechanism behind elevated levels of inflammatory proteins previously detected in HD patients, and how that could affect other aspects of disease pathology, such as muscle wasting.&lt;br/&gt;&lt;br&gt; We isolated cells of the immune response, from both HD patients and three different mouse models of HD, and studied their activity as well as function. These studies led us to further investigate intracellular signaling pathways involved in immune cell-function. We also wanted to investigate gene expression in skeletal muscle from a mouse model of HD and to investigate if and how inflammatory proteins could affect muscle cells in culture.&lt;br/&gt;&lt;br&gt; Our studies of immune cell-activation showed that immune cells from both HD patients and from three different mouse models of HD produce higher levels of inflammatory proteins when activation is triggered. This seems to be caused by the direct interaction of the mutant huntingtin protein with a signaling pathway called NFκB. We could also see that there are changes in the expression of genes involved in muscle contraction and the immune response in skeletal muscle, and by stimulating muscle cells in culture with inflammatory proteins known to be elevated in HD, we could furthermore see a change in these genes.&lt;br/&gt;&lt;br&gt; The results of this thesis warrants for further investigations into the inflammatory response in HD and how it may affect the disease. The findings also support future studies of anti-inflammatory treatment in HD.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Huntingtons sjukdom (HS) är en ärftlig hjärnsjukdom utan botemedel. Den orsakas av en mutation i en gen som kallas huntingtin. Den klassas som en s.k. neurodegenerativ sjukdom, där man ser en förlust av neuroner i delar av hjärnan som kontrollerar kroppsrörelser. Detta resulterar i dansliknande rörelser (chorea) och det är även därför som HS ibland kallas för danssjukan. Traditionellt sett har forskningen kring HS fokuserat kring vad som händer i hjärnan och vad som orsakar neurodegeneration. Det finns dock andra symptom som inte kan förbises, patienter lider av viktminskning, trots normalt intag av näring. De lider också av förtvining av muskler, försämring av kognitiv förmåga, psykiatriska problem, sömnsvårigheter, hjärtsvikt och en subtil ökning av inflammatoriska proteiner. Dessa symptom kan påverka både livskvaliteten samt hur sjukdomen framskrider.&lt;br/&gt;&lt;br&gt; Det övergripande syftet med denna avhandling var att undersöka mekanismen bakom förhöjda inflammatoriska proteiner som tidigare detekterats i patienter med HS och hur dessa skulle kunna påverka andra aspekter av sjukdomen, såsom muskelförtvining.&lt;br/&gt;&lt;br&gt; Vi isolerade celler tillhörande immunförsvaret, från både patienter med HS och från tre olika musmodeller av HS, och studerade deras aktivitet samt funktion. Dessa studier ledde oss fram till att vidare studera intracellulära signaleringsvägar involverade i immunaktivering av celler. Vi ville också undersöka genuttryck i skelettmuskelvävnad från en musmodell av HS och också ta reda på om och hur inflammatoriska proteiner skulle kunna påverka muskelceller i kultur.&lt;br/&gt;&lt;br&gt; Våra studier av immuncellaktivering, visade att immune celler från både HS patienter och musmodellerna producerar högre nivåer av inflammatoriska proteiner efter aktivering. Detta verkar bero på en direkt interaktion mellan muterat huntingtin och en signaleringsväg som heter NFκB. Vi kunde också se förändringar i uttryck av gener involverade i muskelkontraktion och immunförsvaret i skelettmuskel. Genom att i kultur stimulera muskelceller, med inflammatoriska proteiner som tidigare visats förhöjda i HS, kunde vi vidare se en förändring i dessa gener.&lt;br/&gt;&lt;br&gt; De sammanhängande resultaten av den här avhandlingen borgar för fortsatta studier av immunförsvaret i HS och hur det kan påverka sjukdomen. Resultaten stödjer också framtida studier av anti-inflammatorisk behandling av HS.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ed5d9b66-7ae0-437c-a275-fb25f20a9dd5</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Anna_Magnusson_Avhandling_foIr_elektronisk_registrering.pdf">https://portal.research.lu.se/files/3156244/4391183.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8857460</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Huntington&apos;s disease</topic> <topic>peripheral symptoms</topic> <topic>immune response</topic> <topic>muscle atrophy</topic> <topic>cytokines</topic> <topic>gene expression</topic> <topic>JAK/STAT</topic> <topic>NFkB</topic> <topic>IL-6</topic> <topic>TNF-alpha</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-74-8</identifier> <identifier type="oldLupId">4391181</identifier> <part> <detail type="volume"> <number>48</number> </detail> <extent unit="pages"> <total>182</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-04-26T09:30:00+02:00</dateOther> <recordInfo> <recordIdentifier>ed5d9b66-7ae0-437c-a275-fb25f20a9dd5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:06+02:00</recordDateApproved> </recordInfo> </mods>

The individual suffering and the burden on society for these conditions is immense. Genetic contribution for the variance in bone mineral density (BMD) is estimated at around 60–80%, and for OA 50%, leaving a considerable proportion to environmental factors of which exercise is known to influence both. Most intervention studies have shown exercise-induced BMD benefits in young, mid, and old age groups, though all have been short-term. Most studies that have followed changes in BMD with up to ten years of reduced activity level have shown a higher BMD loss than expected by age. Retrospective studies of fracture incidence and OA prevalence have been inconclusive. Little is known about the association between types of exercise in youth and prevalence of total hip arthroplasty (THA) or total knee arthroplasty (TKA) in old age.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We evaluated bone traits in two studies. The first was a 39-year prospective cohort study that followed 46 active male athletes into a mean 29 years of retirement and 24 age-matched controls. The second used a cross-sectional mixed model design that included 329 measurements in 193 active and former male soccer players and 450 measurements in 280 controls, all aged between 18 and 85 years. The first study measured BMD by single-photon absorptiometry (SPA) on both occasions, and with dual energy X-ray absorptiometry (DXA), peripheral computed tomography (pQCT) and quantitative ultrasound (QUS) at follow-up. The second study used DXA. Fracture incidence was evaluated in two retrospective cohort studies, one including 397 former male soccer players and 1368 age-matched controls and the second 709 former male athletes in a variety of sports and 1368 age-matched controls. The prevalence of hip and knee OA and arthroplasty was also evaluated in the second study.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the first study we found no changes in relative leg BMD levels [Δ Z-score 0.0 (95% CI –0.4, 0.4)] in athletes from activity into retirement. At follow-up, former athletes still had 0.5 to 1.2 standard deviations (SD) higher BMD, bone size, and strength index than controls (all p&amp;lt;0.05). In the second study, total body BMD, leg BMD, and femoral neck area were 0.3 to 0.5 SD higher in 30 or more years retired athletes than in controls (all p&amp;lt;0.05). Former male athletes had a 50% [RR 0.5 (95% CI 0.3, 0.9)] and former soccer players had a 60% [RR 0.4 (95% CI 0.2, 0.9)] lower risk respectively of any fragility fracture incidence than controls (both p&amp;lt;0.05), and two times higher age-adjusted risk of a hip and/or knee OA [OR 1.9 (95% CI 1.5, 2.3)], as well as a hip and/or knee arthroplasty [OR 2.2 (95% CI 1.6, 3.1)]. After adjustment for differences in BMI, occupational load, and previous soft tissue knee injury, there was no increased risk of knee OA in former impact athletes while the risk remained in non-impact athletes [OR 3.2 (95% CI 1.5, 6.9)].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis infers that exercise-associated benefits in BMD and bone size remain long-term after sports, and that former athletes are at lower fracture risk than controls. In contrast, the risk of hip and/or knee OA and THA and/or TKA is higher in former athletes than in controls. The higher risk of knee OA in former athletes is associated with a knee injury in impact but not in non-impact athletes.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Osteoporos (benskörhet) är ett tillstånd som definieras av låg benmassa och ett tillstånd som ökar med stigande ålder. Sjukdomen i sig är symptomfri men ökar risken för frakturer. Frakturer i kota, axel, handled, bäcken, och höft efter 50 års ålder är ofta förknippade med osteoporos och ca 70 000 sådana frakturer inträffar årligen i Sverige. Även artros (ledsvikt) i höft- och knäleder är vanligt hos äldre. Artros leder till belastningssmärta, vilovärk, stelhet och svullnad. Hjälper ingen annan behandling kan man ersätta den förstörda leden med en protes och årligen utförs i Sverige ca 30 000 sådana ledprotesoperationer i höft- och knäleder. För både osteoporos och artros är det individuella lidandet stort, samhällskostnaderna höga och stora resurser läggs därför ner på att förebygga tillstånden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Precis som för de flesta sjukdomar anses osteoporos och artros till stor del vara beroende av genetiska faktorer. Det finns dock även en mängd påverkbara riskfaktorer för sjukdomarna som graden av fysisk aktivitet, rökning för osteoporos och fetma för artros. Fysisk aktivitet i unga år leder till ett större skelett med högre benmassa, gynnsamma förändringar som är kopplade till låg frakturförekomst. Men det är oklart om dessa gynnsamma effekter kvarstår under resten av livet. Man vet inte heller om träning i unga år skyddar mot osteoporosfrakturer i hög ålder. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hög fysisk aktivitet verkar också öka risken för att drabbas av symtomgivande menisk- och korsbandsskador i knäna. Sådana skador leder till ökad risk för artros. Om hög träningsnivå utan (symtomgivande) skador leder till ökad artros är däremot oklart. Det är också oklart om olika typer av träning ger upphov till olika risk att drabbas av artros samt vilken betydelse mjukdelsskador i knälederna har för uppkomsten av artros inom olika typer av idrotter. Syftet med avhandlingen var att hos män studera långtidseffekterna på skelett och leder efter hög fysisk aktivitet i ungdomsåren.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete I följde vi benmassan och muskelstyrkan hos 46 idrottsmän och 24 kontrollpersoner under i genomsnitt 39 år. Den första mätningen gjordes när idrottsmännen var aktiva, den andra i genomsnitt 29 år efter att de hade avslutat sin idrottskarriär. Som förväntat hade idrottsmännen när de var aktiva högre benmassa och starkare muskulatur än kontrollpersonerna. Vid uppföljningen var det ingen skillnad i muskelstyrka medan benmassan fortfarande var högre hos de f.d. idrottsmännen. Det verkar alltså som om idrottsmän trots att de avslutat sin idrottskarriär tre decennier tidigare hade kvar sin höga benmassa.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete II undersökte vi risken att utveckla artros och behovet av ledprotes i höft- och knäleder hos f.d. idrottsmän och en kontrollgrupp. Vi undersökte 709 före detta idrottsmän med en medelålder på 69 år och 1368 kontrollpersoner i samma åldrar. Genom ett frågeformulär tog vi reda på deras längd och vikt samt om de hade fått diagnosen artros i höft- eller knäleder av en läkare samt om de hade blivit opererade med en protes i någon av dessa leder. Vi fann då att de f.d. idrottsmännen löpte dubbelt så hög risk att drabbas av artros i höft eller knä och att ha genomgått en ledprotesoperation i jämförelse med kontrollgruppen. Efter att vi tagit hänsyn till skillnader i tidigare arbetsbörda, vikt, och mjukdelsskador i knäet så fann vi inte längre någon ökad risk hos de f.d. kontaktidrottsmännen att drabbas av knäartros medan de f.d. idrottsmännen i individuella/uthållighets/icke kontakt grenar hade en tre gånger högre risk jämfört med kontrollgruppen. Det verkar alltså som om den ökade risken för uppkomst av OA i knälederna hos f.d. idrottsmän är beroende på olika mekanismer i olika idrotter.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete III undersökte vi samma individer som i delarbete II men tittade på frakturrisken hos f.d. idrottsmän och kontrollpersoner, utvärderat via det frågeformulär som beskrivs ovan. Vi fann då att de f.d. idrottsmännen löpte 30 % lägre risk att drabbas av fraktur efter avslutad karriär och 50 % lägre risk att efter 50 års ålder drabbas av en benskörhetsfraktur jämfört med kontrollgruppen. Vår slutsats blev att idrottande i ungdomen hos män är kopplat till en lägre frakturrisk senare i livet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete IV inkluderades i den första delstudien 329 skelett- och muskelmätningar genomförda på 193 manliga fotbollsspelare och 450 mätningar genomförda på 280 kontrollpersoner. Samtliga individer var mellan 18 och 85 år gamla och vissa individer mättes alltså två gånger. I den andra delstudien inkluderades 397 f.d. manliga fotbollspelare och samtliga 1368 kontrollpersonerna ur den grupp som beskrivits i delarbete II. Vi fann då att benmassa och muskelmassa var högre bland de aktiva fotbollspelarna än bland kontrollpersonerna men att denna skillnad också sågs hos de f.d. fotbollspelarna som hade avslutat sin karriär mer än 30 år tidigare jämfört med kontrollgruppen. Vi fann också att de f.d. fotbollspelarna löpte 40 % lägre risk att drabbas av fraktur efter avslutad karriär och 60 % lägre risk att efter 50 års ålder drabbas av en benskörhetsfraktur jämfört med kontrollgruppen. Våra slutsatser blev att de gynnsamma skeletteffekter som syns hos aktiva fotbollspelare kvarstår lång tid efter avslutad idrottskarriär och att dessa fynd även är kopplade till en låg frakturrisk senare i livet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammantaget verkar det som idrottande på hög nivå hos unga män är kopplat till ett starkt skelett och låg frakturrisk senare i livet men också till mer artros och ett större behov av ledprotesoperationer i höften och knäet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/36c1e800-1a4a-4919-a358-9ff173091a1d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="tveit_final_kappa13-04-10_utan_papper.pdf">https://portal.research.lu.se/files/3156423/3633566.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4113862</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>arthroplasty</topic> <topic>BMD</topic> <topic>bone mass</topic> <topic>bone geometry</topic> <topic>bone size</topic> <topic>exercise</topic> <topic>former athletes</topic> <topic>fracture</topic> <topic>fragility fracture</topic> <topic>knee injury</topic> <topic>osteoarthritis</topic> <topic>osteoporosis</topic> <topic>hip injury</topic> <topic>runners</topic> <topic>soccer</topic> <topic>total joint replacement</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-20-8</identifier> <identifier type="oldLupId">3633551</identifier> <part> <detail type="volume"> <number>2013:50</number> </detail> <extent unit="pages"> <total>168</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-05-08T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>36c1e800-1a4a-4919-a358-9ff173091a1d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:10+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:10+02:00</recordDateApproved> </recordInfo> </mods>

The specific causative agent(s) are unknown but may originate from degradation processes in damp materials, microbial growth, or a combination of these phenomena. The health impact of dampness in buildings is a politically, legally, and economically important question. Scientists at the U.S. EPA and Lawrence Berkeley National Laboratory have estimated that the symptoms of 4.6 of the total of 21.8 million asthmatics in the USA are caused by indoor dampness and mold to an annual cost of 3.5 billion dollars. &lt;br/&gt;&lt;br&gt; Mycotoxins are secondary metabolites produced by molds which may be e. g. cytotoxic (e. g. macrocyclic trichothecenes produced by Stachybotrys chartarum), genotoxic (e. g. sterigmatocystin and aflatoxins produced mainly by Aspergillus spp. including A. versicolor and A. flavus), or immunosuppressive and neurotoxic (e. g. gliotoxin produced by Penicillium spp. and Aspergillus spp. e. g. A. fumigatus). Airborne mycotoxins have been demonstrated in water-damaged buildings using both ELISA and mass spectrometry. However, whether mycotoxins at the concentrations found in mold-damaged environments represent a health risk upon inhalation is not known. The mechanisms for mycotoxin uptake, metabolism, and interaction e. g. with other fungal constituents such as proteins and (1→3)-β-D-glucan (a fungal cell membrane constituent) are poorly understood. &lt;br/&gt;&lt;br&gt; In this project analytical methods for the detection and determination of selected mycotoxins using GC-MS and HPLC-MS were developed. The methods were applied to 167 mold-contaminated building material samples, of which 67 % were mycotoxin positive. Thus, many molds not only posess the genetic capacity to produce mycotoxins but do it regularly in water damaged indoor environments. In addition, we demonstrated mycotoxins in dust settled in the breathing zone in indoor environments where severe mold-contamination was identified on building materials. We thereby confirm that mycotoxins on such materials can become airborne and thus inhalable. &lt;br/&gt;&lt;br&gt; This project is an example of fruitful national and international inter-disciplinary collaboration between the building industry, companies specialized in remediation measures, and universities.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/007da6bd-c6c8-441e-900d-1f2fdd72e189</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa_final_version2.pdf">https://portal.research.lu.se/files/3156529/1265711.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1791155</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Gas chromatography</topic> <topic>Mass spectrometry</topic> <topic>Mycotoxin</topic> <topic>Indoor Air</topic> <topic>Ergosterol.</topic> <topic>Mold</topic> <topic>High pressure liquid chromatography</topic> <topic>Dust</topic> <topic>Building materials</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-65-1</identifier> <identifier type="oldLupId">1265413</identifier> <part> <detail type="volume"> <number>2008:112</number> </detail> <extent unit="pages"> <total>154</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-06T09:30:00+01:00</dateOther> <recordInfo> <recordIdentifier>007da6bd-c6c8-441e-900d-1f2fdd72e189</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:12+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:12+02:00</recordDateApproved> </recordInfo> </mods>

Fotsår är en vanlig komplikation vid diabetes, och sådana svårläkta sår leder till c:a 700 diabetesrelaterade amputationer årligen. Såväl såren som amputationssituationen orsakar funktionshinder, smärta, sociala bekymmer samt psykisk stress för dem som drabbas. Att utveckla nya och förbättrade behandlingar för sårläkning är angeläget, men det finns idag igen riktigt bra sårläkningsmodell som lämpar sig för forskning inom detta område. &lt;br/&gt;&lt;br&gt; Syftet med detta projekt var att utveckla en ny djurmodell för diabetisk sårläkning som kan användas i forskningsarbetet. Modellen skulle inte bara medge möjlighet att värdera nya behandlingar för diabetiska sår i vid bemärkelse utan också kunna belysa betydelsen av olika former av cellterapi och genterapi. Eftersom grishud har stora likheter med människans hud valdes grisen som bas för den diabetiska sårläkningsmodellen.&lt;br/&gt;&lt;br&gt; I det första delprojektet visades att inducerad diabetes hos grisar leder till försämrad sårläkning som i allt väsentligt liknar den hos människa med diabetes. &lt;br/&gt;&lt;br&gt; I det andra delprojektet visades att sårläkningen förbättrades hos diabetiska grisar genom att tranplantera antingen hudceller eller bindvävsceller. Resultaten från studien ledde också till tanken att använda dessa celler som bärare nya gener med läkningsbefrämjande effekter.&lt;br/&gt;&lt;br&gt; I det tredje delprojektet användes således hudceller som transportmedel for en gen som producerar tillväxtfaktorn insulin like growth factor I (IGF-1). Transplantation av dessa IGF-1-innehållande celler visade kraftig utökad produktion av IGF-1 i sårområdet samt förbättrad sårläkning.&lt;br/&gt;&lt;br&gt; I det fjärde delprojektet användes hudceller från en annan donator med en gen som producerar tillväxtfaktorn epidermal growth factor (EGF). Transplantation av dessa celler i normala icke-diabetiska sår ledde till kraftig utökad produktion av EGF i sårområdet samt förbättrad sårläkning.&lt;br/&gt;&lt;br&gt; I det femte delprojektet användes kunskapen från fjärde delprojektet, och hudceller med tillsatt gen för EGF tranplanterades i sår på diabetiska grisar. Produktionen av EGF blev kraftigt ökad i sårområdet och läkningen blev påfallande förbättrad.&lt;br/&gt;&lt;br&gt; Tillsammans har dessa studier lett till utvecklingen av en ny diabetisk sårläkningsmodell på gris och denna lämpar sig väl för forskning kring diabetisk sårläkning. Studierna har därtill lett till insikter om hur celler kan användas i kombination med genterapi för att förbättra sårläkning vid diabetes.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/895cecea-30b1-4e48-ab9f-bffa62d2d9a8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Patrik_Velander_kappa.pdf">https://portal.research.lu.se/files/3162914/1687423.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3334718</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>IGF-1</topic> <topic>Gene therapy</topic> <topic>Diabetes</topic> <topic>Animal model</topic> <topic>EGF</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-02-0</identifier> <identifier type="oldLupId">1687409</identifier> <part> <detail type="volume"> <number>2010:86</number> </detail> <extent unit="pages"> <total>59</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-10-21T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>895cecea-30b1-4e48-ab9f-bffa62d2d9a8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:19+02:00</recordDateApproved> </recordInfo> </mods>

Q-compounds have shown efficacy in several different models of autoimmune diseases such as experimental autoimmune encephalomyelitis (EAE) and collagen induced arthritis. However, the mechanism of action is still poorly understood. In this thesis we have tried to find the mechanism of action of 5757 using different inflammatory models. &lt;br/&gt;&lt;br&gt; We studied the effect of 5757 on generation of cells from bone marrow in cultures supplemented with different colony stimulating factors (paper I). CD11c+ cells increased in presence of 5757 while GR1+ cells decreased and also proliferated less in presence of 5757. These results were seen in GM-CSF and M-CSF stimulated cultures but not in cultures stimulated with G-CSF. 5757 did not affect the function of the generated cells. &lt;br/&gt;&lt;br&gt; We also studied the effect of 5757 in amelioration of inflammatory disease. We used EAE, the animal model for the human autoimmune disease multiple sclerosis for this purpose (paper II). Treatment of mice with 5757 effectively reduces induction of EAE. This mechanism is an early effect since treatment with 5757 during the first five days after induction also reduced EAE development. Influx of T cells and myeloid cells to CNS was significantly reduced in these mice. EAE is a T cell dependent disease and the activation of antigen-specific disease-causing T cells occurs early in the peripheral lymphoid organs. In vivo proliferation of antigen-specific T cells and production of the effector cytokines IFN-γ and IL-17 were reduced in mice treated with 5757. &lt;br/&gt;&lt;br&gt; To study the effect of 5757 on cell migration we used a sterile peritonitis model were necrotic cells or alum were used to induce inflammation (paper III). 5757 reduced migration of inflammatory monocytes and eosinophils to inflamed tissue. We also showed that the effect of 5757 on cell recruitment to inflamed tissue is dependent of Receptor of Advanced Glycation End products (RAGE) and that expression of this receptor by hematopoietic cells is important for the effect of 5757. &lt;br/&gt;&lt;br&gt; Taken together this thesis shows that i) 5757 affects generation of immune cells in vitro, ii) 5757 treatment affects T cell activation and thereby reducing EAE and ii) that 5757 reduce migration of inflammatory cells to inflamed tissue in a RAGE-dependent way.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/665a1374-12e5-44e8-8f75-eb329dcff58a</url> </location> </relatedItem> <originInfo> <publisher>Immunology</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-38-3</identifier> <identifier type="oldLupId">3917527</identifier> <part> <detail type="volume"> <number>2013:68</number> </detail> <extent unit="pages"> <total>84</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-06-14T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>665a1374-12e5-44e8-8f75-eb329dcff58a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:21+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:21+02:00</recordDateApproved> </recordInfo> </mods>

How the nervous system controls this amount of degrees of freedom in motor execution is a question under vigorous debate. In an ambition to explore related aspects of motor control we conducted parallel electrophysiological recordings of motor circuits in the cortex and basal ganglia in the consciously behaving rodent during the execution of various motor behaviors.&lt;br/&gt;&lt;br&gt; To be able to further explore the relevance of neuronal activation patterns for different behaviours within these motor structures, we developed two methods - one focusing on increasing the amount of information acquired from the neuronal recordings and the other on improved motion tracking. The first method enabled a flexible electrode construction for targeting of multiple regions of the brain simultaneously. In the motion tracking system an anatomically defined model of the rodent paw was developed. With high resolution recordings a detailed reconstruction of a complex movement permitted differentiation of multiple kinematic parameters that could be related to the electrophysiological recordings. In experiments employing a reach and grasp paradigm, we were able to correlate the neuronal code to a previously suggested subdivision of the compound movement into functional sub-components, in effect validating the method.&lt;br/&gt;&lt;br&gt; In further studies we utilized the 6-OHDA rodent model of Parkinson’s disease, where motor control is impaired. Here we found that levodopa induced-dyskinesia was tightly associated with a strong oscillatory phenomenon in the motor cortex, and that stopping the oscillation locally was sufficient for alleviation of motor symptoms. By expanding the neuronal recordings using the developed electrode we showed that different states of the disease could be reliably discerned. When comparing these disease states with a control state, we could thus assess the effect of drugs in their ability to normalize disease-relevant signals. The validity of this procedure was verified by correlation between the behavioral and neuronal measures. These experiments demonstrate that neuronal measures of internal states can be utilized for evaluation of new treatment strategies and have a high potential in aiding drug development for diseases without clear behavioral phenotypes.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Nervsystemet är sannolikt en av de mest vidunderliga strukturer som skapats i detta universum - denna avhandling hade till exempel varken kunnat skrivas eller läsas utan det. Som av en slump handlar den också om just nervsystemet och läsande och skrivande är två exempel på olika funktioner som möjliggjorts på grund av det. Även om dessa utgör funktioner som är ovanliga utanför vår egen art, människan, så skapas alla sorters intryck och uttryck utifrån samma fundament: genom en tvåsamhet mellan sensorik och motorik.&lt;br/&gt;&lt;br&gt; Inom neurovetenskapen finns en uppsjö av frågor och tekniker som tillåter studier av nervsystemets olika funktioner och i denna avhandling ligger fokus på hur motorik programmeras av diverse hjärnstrukturer under olika tillstånd. Genom att implantera elektroder som mäter aktivitet hos nervceller i specifika hjärnområden samtidigt som olika beteenden utrycks har vi kunnat mäta vilka förändringar i nervcellers signalering som kan kopplas till den motoriska aktiviteten. Vanligtvis görs detta genom en manuell klassning av diverse beteendeegenskaper som sedan associeras till den uppmätta nervcellsaktiviteten, men då detaljerade korrelationer kräver hög upplösning i både tid och rum så blir detta ofta en onödigt krävande process. För att få den detaljnivå som krävs för att kunna utröna vilka parametrar i ett beteende som är kontrollerade i de registrerade hjärnstrukturerna så utvecklade vi ett datoriserat system som automatiskt klassar beteendet med avseende på parametrar såsom vinklar över leder, rörelseriktning och hastighet. Detta gjordes på ett beteende där en råtta tar en godisbit med hjälp av en sträckrörelse med tassen, som är jämförbar med vissa målinriktade handrörelser i människor. Genom att samtidigt mäta nervcellsaktivitet från två hjärnområden kända för sin inblandning i motorik kunde vi med denna teknik visa att den fullständiga rörelsen kodades neuronalt på ett sätt som tidigare hade föreslagits utav detaljerade beteendestudier - i form av mindre, funktionella komponenter som sätts samman i skapandet av den komplexa rörelsen. Förutom att ge en indikation på ett vis som hjärnan under normala omständigheter skulle kunna programmera rörelser, så indikerade det att metoden för beteendeklassificering är en fördelaktig teknik att utnyttja i mer detaljerade framtida studier.&lt;br/&gt;&lt;br&gt; I nästkommande studie ville vi också studera samma strukturers inflytande under ett sjukdomstillstånd, för att se om de förändringar av beteendet som sjukdomen skapar kunde förklaras av förändringar i den uppmätta nervcellsaktiviteten. I människor och djurmodeller av Parkinson’s sjukdom som behandlas med en effektiv symptomlindrande medicin kallad levodopa så uppkommer vanligtvis biverkningar i form av ofrivilliga och syfteslösa rörelser kallade dyskinesier. Under detta biverkningstillstånd fann vi en kraftig förändring i signaleringen i en känd men i situationen förbisedd hjärnstruktur samtidigt som symptomen uppvisades. Vi hade härmed hittat en potentiellt ny mekanism på en ny plats i hjärnan som teoretiskt skulle kunna blir ett mål för att motverka biverkningarna. Genom att behandla bara denna struktur, motorhjärnbarken, med en experimentell medicin som motverkar den primära behandlingen så kunde vi ytterligare stärka sambandet mellan symptombilden och den den onormala signalen, då stävjandet av den också hämmade de ofrivilliga rörelserna. Detta var glädjande eftersom i det fall biverkningar från en i övrigt fördelaktig behandling kan hindras så blir ursprungssjukdomen ett mycket mindre problem för patienten.&lt;br/&gt;&lt;br&gt; Då vi vid detta lag sett att de hjärnstrukturer vi mätt ifrån varit inblandade på olika vis i de olika tillstånd vi studerat så ville vi utveckla elektroderna för nervcellsmätningarna så att de skulle kunna anpassas för att mäta från många fler hjärnstrukturer samtidigt. Vi antog att om alla de områden vi mätte ifrån bidrog med unik fakta om vad som sker, så kommer den totala informationen från dessa experiment kunna öppna upp för nya frågeställningar och användningsområden. I samma uppställning med levodopa-behandlade parkinson-djur som innan kunde vi genom att samtidiga mätningar från åtta olika hjärnområden per hjärnhalva hitta skillnader mellan normala och sjukliga tillstånd som förr inte kunnat beskrivas med samma detaljrikedom. Denna samtida beskrivning av sjukt och friskt tillät oss att testa mediciner för att se hur en behandling av ett sjukt tillstånd påverkade hjärnsignalerna i stora delar av hjärnan, vilket kunde jämföras med signalerna från det friska tillståndet. På så sätt kunde vi utöver den tydliga påverkan på beteendet också se hur bra en medicin verkade genom att direkt titta på hjärnsignalerna. Eftersom en medicins ospecifika påverkan på beteenden kan vara väldigt svår att klassificera med standardiserade skalor anpassade för specifika sjukdomssymptom, så blir detta ett efterlängtat sätt att istället utnyttja kroppsegna signaler för utvärdering av en medicins effekt. För psykiatriska sjukdomar till exempel, där förändringar i beteende är mindre uppenbara än i motoriska sjukdomar, så skulle detta kunna ge en inblick i effekten av ett läkemedel som kan användas för läkemedelsutvecklingssyften för dessa i dagsläget svårbehandlade tillstånd. I sin helhet har innehållet i denna avhandling bidragit till att komplettera existerande kunskap om nervsystemets roll i motorik under normala och sjuka förhållande, till den grad att nya frågor inom ämnet kan börja ställas och i sinom tid besvaras. Med ett sådant förfarande kommer förhoppningsvis den potentiella nyttan av resultaten motivera att både grund- och applicerad forskning bör vara en naturlig del av alla samhällen.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/588f1faf-e9b9-4ee7-966a-7f6f84fdfcea</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Tamte_Kappa.pdf">https://portal.research.lu.se/files/3163803/8776834.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">56351277</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Integrative Neurophysiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Neurophysiology</topic> <topic>Electrophysiology</topic> <topic>Pharmacology</topic> <topic>Motor Systems</topic> <topic>Voluntary movements</topic> <topic>Philosophy</topic> <topic>In vivo</topic> <topic>Corticostriatal</topic> <topic>Parkinson&apos;s disease</topic> <topic>Dyskinesia</topic> <topic>Levodopa</topic> <topic>Multiple Electrode Arrays</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-263-4</identifier> <identifier type="oldLupId">8776791</identifier> <part> <detail type="volume"> <number>2016:37</number> </detail> <extent unit="pages"> <total>162</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/26740532</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/25569979</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/23175810</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/22306061</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-03-31T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>588f1faf-e9b9-4ee7-966a-7f6f84fdfcea</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:28+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:28+02:00</recordDateApproved> </recordInfo> </mods>

Sweden experienced an epidemic of clinically detected celiac disease in children younger than 2 years of age, partly due to changes in infant feeding practices, were the amount of gluten and age at introduction was changed. However, it was not clear if the increase in clinically detected children was due to more CD cases being detected due to symptoms and thus previously undiagnosed, or if it was a true change in CD prevalence. In the revised 2012 ESPGHAN criteria for CD diagnosis, a small intestinal biopsy is no longer mandatory in symptomatic patients when the tTG-IgA levels exceeding ten times the upper limit of normal (&amp;gt; 10xULN) in combination with positivity for EMA and HLA- DQ2 and/or DQ8. Biopsy is still recommended in asymptomatic screening detected cases, were symptoms suggestive of CD is the main difference of the approach to the diagnostic process. Recent studies have shown that screening also detects symptomatic cases, whereas many are unaware of symptoms until after starting on the GFD. Furthermore, there are many pitfalls in the diagnostic process, were the choice of biopsy method and the histopathological evaluation have a significant impact on the diagnostic outcome. To use a capsule device to obtain mucosal specimens was previously considered to be gold standard, but the lesions may be patchy and missed if only one mucosal specimen is obtained. In a clinical setting there can be an advantage of using endoscopy due to the ability to take multiple biopsies. The treatment with a gluten-free diet is a life-long challenge and entails social sacrifices, which may effect the adherence. To be a teenager at the time of diagnosis can be a negative factor, alongside with being screening detected. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Objectives:&lt;br/&gt;&lt;br&gt; To study the total prevalence of clinical and screening detected celiac disease in children born during the Swedish epidemic, and to investigate the effect and accuracy in each step of the diagnostic process to obtain CD diagnosis. Furthermore, to investigate the correlation between the level of the serological markers (tTG-IgA) and the degree of gluten induced enteropathy and applying the revised 2012 ESPGHAN guidelines on screened CD cases.&lt;br/&gt;&lt;br&gt; Additionally, to evaluate the adherence to the GFD in adolescents with screening detected CD.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Method:&lt;br/&gt;&lt;br&gt; We performed a two-phased screening study, ETICS (Exploring the Iceberg of Celiacs In Sweden). A total of 13 279 twelve year old children were investigated, belonging to two different birth cohorts. The first birth cohort was born during the epidemic period in 1993 and the second cohort was born in the post-epidemic period in 1997. The prevalence of clinically detected CD was gathered from the National Swedish Childhood Celiac Disease Register and the total prevalence was estimated together with the ETICS screening study. Screening for CD was conducted by using a serological marker, anti-tissue transglutaminase antibodies (tTG-IgA). The CD diagnosis was confirmed by a small intestinal biopsy using either a suction capsule or endoscopy according to local routine in the study sites. The clinical diagnostic procedure was reviewed by performing endoscopic re-biopsies in children who hade normal or inconclusive primary biopsy. All of the mucosal specimens were re-evaluated by an expert pathologist and when disagreement with the local pathologist, a second expert pathologist re-evaluated the specimens to reach a diagnostic consensus. &lt;br/&gt;&lt;br&gt; The correlation between the degree of enteropathy and the level of the serological markers (tTG-IgA) was investigated by comparing the level of tTG-IgA at the time of biopsy to the degree of gluten induced enteropathy. The revised ESPGHAN guidelines for symptomatic CD was hypothetically applied to the screening cases to evaluate if the biopsy could have been omitted.&lt;br/&gt;&lt;br&gt; The adherence to the GFD was measured both by the change of tTG-IgA levels after 12 months and by self-reported questionnaires were the response alternatives were; always, often, sometimes and never.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Results:&lt;br/&gt;&lt;br&gt; The total prevalence of CD in children born 1993 was 2.9%, with two thirds of the cases being unrecognized. Endoscopic biopsies were inconclusive in 0.6% compared to 7.4% of the capsule biopsies and patchy enteropathy was found in 9% of the children who had conclusive fractions from both proximal and distal duodenum. By controlling the diagnostic process several CD cases were found, re-biopsy resulted in 8 new cases and re-evaluation of all mucosal specimens by an expert pathologist, resulted in additional 6 CD cases. In our screened population all cases with tTG-IgA levels exceeding ten times of normal values (&amp;gt; 10xULN) at a cut-off of 5 U/mL got CD diagnosis and all except for one child got CD diagnosis at a cut-off of 3 U/mL, were the majority had Marsh 3 lesions. The adherence was high in the screened population where 83% had tTG-IgA levels &amp;lt;5 U/mL after 12 months on GFD. Most of the children reported to always (75%) or often (14%) be adherent. There where children who reported to always be adherent but the serological markers were not yet normalized after 12 months. All of these children had halved their initial values, whereof the majority (85%) of these children initially had high serological markers &amp;gt;50 U/mL.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Conclusions:&lt;br/&gt;&lt;br&gt; The prevalence of 3% was unexpectedly high, whereof two thirds were previously unrecognized. This finding underlines the fact that many CD cases remain undiagnosed, but also that the exposure to an unfavourable infant feeding in this birth cohort may have affected the high total prevalence. &lt;br/&gt;&lt;br&gt; The accuracy in the diagnostic procedure is dependant on various factors, where biopsy method and the pathological evaluation are crucial in finding the CD cases. The preferable method for biopsies to be recommended is by using endoscopy and to sharpen the diagnostics to perform re-biopsies and/or re-evaluating in normal or inconclusive biopsies. The revised ESPGHAN guidelines for symptomatic cases seems to be applicable even on screening detected cases, due to the correlation between high levels of tTG-IgA and degree of enteropathy in this group. Screening detected children have a high adherence to the treatment with GFD, which can be measured by using self-reported questionnaires in combination with the change of the serological markers.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bakgrund och syfte med avhandlingen&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Glutenintolerans, celiaki är en av de vanligaste kroniska sjukdomarna bland barn och innebär att man inte tåler gluten, som är ett protein och finns i vete, råg och korn. &lt;br/&gt;&lt;br&gt; Tunntarmen har en veckad slemhinna med fingerlika utskott , tarmludd och hela tarmen har en yta på 250 kvadratmeter, vilket är lika stort som en tennisplan. Den stora ytan är viktig för att tunntarmen ska kunna ta upp all näring. Gluten skadar tarmluddet och det första som händer är att antalet försvarsceller, så kallade T-lymfocyter, ökar i tarmen, därefter minskar tarmludden i höjd och tarmen blir sedan helt slät. Det leder i sin tur till att tunntarmens yta som suger upp näring minskar, Blodbrist med både järnbrist och brist på vitaminerna B12 och folsyra är vanlig bland de med obehandlad glutenintolerans. Många vuxna med oupptäckt glutenintolerans har tecken på benskörhet, så kallad osteoporos, vilket är orsakat av brist på vitamin D och kalcium. I tarmluddet finns även enzymet laktas som bryter ner mjölksockret, laktos, i maten, vilket också kan minska och leda till symtom när man dricker mjölk. För att man ska kunna få glutenintolerans måste man ha vissa genetiska förutsättningarna, vilket innebär att man har generna (HLA-DQ2 /DQ8). Dessa gener anges vanligen förekomma hos 25% av normalbefolkningen, men i Sverige har en förekomst på 53% rapporterats. Det är också nödvändigt att man äter gluten innehållande livsmedel ex bröd, pasta, pizza. Vilka faktorer som påverkar att sjukdomen utvecklas hos den enskilde individen är bara delvis kända. Glutenintolerans finns i 1-2% av den svenska befolkningen och är dubbelt så vanligt hos kvinnor som hos män. Symtomen på glutenintolerans varierar men hos små barn är det ofta besvär ifrån tarmen, såsom diarré eller förstoppning, dåligt näringsupptag och dålig tillväxt som dominerar. Många med celiaki har inga tydliga symtom och en del har inga symtom, vilket innebär att om man inte letar aktivt efter dessa patienter genom blodprov och testa för gluten intolerans , så förblir de oupptäckta. Mörkertalet är stort och många är fortfarande odiagnosticerade .&lt;br/&gt;&lt;br&gt; Det har rapporterats att personer med celiaki i medeltal har väntat i 10 år från första symtom till diagnos. Kunskapen om celiaki har ökat och man har börjat testa i vissa grupper som man vet har en ökad risk för att utveckla celiaki, exempelvis barn med diabetes eller barn med Down alt Turners syndrom. &lt;br/&gt;&lt;br&gt; I mitten av 1980-talet började svenska barnläkare hitta oväntat många fall av glutenintolerans bland småbarn. Den svenska epidemin varade under åren 1984-1996 och ökningen av kliniskt diagnosticerade barn var nästan fyrfaldig, för att sedan åter sjunka till samma nivåer som tidigare. Forskare i Umeå tillsammans med en grupp inom svensk barnläkarförening startade ett nationellt celiaki register . Man fann tre faktorer som delvis skulle kunna förklara epidemin. Den första var att i början av 1980 talet hade det kommit nya rön om att det var lämpligt att minska mängden protein i spädbarnsmaten , som välling och gröt och burkmat. Det ledde till att industrin minskade mängden mjölk i produkterna, men för att få en smaklig produkt tillsattes mjöl, vilket i vissa produkter ledde till att halten mjöl mer än dubblerades. Ungefär samtidigt kom en ny rekommendation till föräldrar att de skulle vänta med att introducera gluten i spädbarnskosten tills sex månader, i stället för fyra månaders ålder. Rådet innebar dock att fler barn började äta högre halter mjöl i samband med att de slutade ammas, vilket senare har visat sig vara en riskfaktor. Man återgick därför till att rekommendera föräldrar att föra in gluten mera gradvis, gärna parallellt med amning och industrin minskade halten vetemjöl i sina produkter, vilket resulterade i att epidemin fick ett slut.&lt;br/&gt;&lt;br&gt; Docent Anneli Ivarsson har i sina forskningsstudier kunnat konstatera att mängden mjöl i spädbarnkosten har stor betydelse och att ge gluten under pågående amning har skyddande effekt. I en senare studie av barn med risk generna för glutenintolerans har man sett att svenska barn har dubbelt så hög risk som amerikanska barn att utveckla glutenintolerans, även om svenska barn ammas längre, skillnaden var att dock att svenska barn fick gluten introducerat i kosten, tidigare i livet jämfört med barn i andra länder. Amning har en skyddande effekt mot infektioner och det har visat sig att barn som är födda på sommarhalvåret har en större risk att får glutenintolerans jämför med barn födda på vintern. Detta fynd kunde kopplas till att barn som föds på sommaren slutar att amma och får gluten under vinterhalvåret då de också utsätts för infektioner. Rotavirus är ett vanligt virus som orsakar diarrée och kräkning hos ffa de små barnen och som ofta leder till allvarlig uttorkning och sjukhusvård. Detta virus är också kopplat till att ökad risk för glutenintolerans pga att viruset skadar tarmen så att gluten kan komma över tarmbarriären och starta en immunologisk process. Det finns en generell ökning av glutenintolerans i västvärlden och man spekulerar om det finns något i livsstilen som påverkar ex att snabbmaten innehåller mycket vetemjöl som har förbehandlats.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Under 1970 talet, då tunntarmskapslarna infördes som klinisk rutin, fastställdes diagnostiska kriterier för glutenintolerans. Dessa innebar att diagnosen ställdes genom att man utförde tre på varandra följande tunntarmsbiopsier, en initial biopsi vid utredning av symtom, en efter en period med behandling med glutenfri kost och en efter en period då barnet hade ätit normalkost. När de serologiska markörerna introducerades i kliniken reviderades diagnoskriterierna 1991 till att gälla en enda biopsi för att faställa tunntarmsskada. ESPGHAN, den europeiska barngastroenterologiska föreningen( European Society for Paediatric Gastroenterology, Hepatology and Nutririon) kom 2012 med reviderade riktlinjer, som är baserade på att höga värden av de serologiska markörerena korrelerar till en högre grad av tarmskada. I praktiken innebär dessa rekommendationerna att om man har en stark misstanke om glutenintolerans pga att barnet har symtom och barnet har en 10-falidgt förhöjda serologiska markörer i blodet, så kan man avstå ifrån att göra en tunntarmsbiopsi. Tunntarmsbiopsi innebär att man undersöker tarmen med antingen med ett kapsel instrument eller ett endoskopsiskt instrument .Tunntarmsbiten skickas sedan till en patologläkare (specialist läkare i sjukdomslära) som preparerar biten i formalin och färgar med olika metoder för att sedan i mikroskopet kunna bedöma om barnet har glutenintolerans. Genom att ta ett blodprov mäter man nivån på anti-kroppar och vid höga nivåer är det med stor säkerhet som man kan anta att skadan i tarmen är förenlig med glutenintolerans. Man måste också kontrollera att barnet har ärftlighet för glutenintolerans och att den glutenfria kosten har effekt innan man ställer diagnosen. Dessa kriterier gäller dock bara barn med symtom Tunntarmsbiopsi är fortfarande obligatoriskt för barn som hittas vi screening. Det har dock framkommit att man hittar barn som har symtom även ibland de screening upptäckta barnen, symtom de blir medvetna om först efter att ha startat behandling med den gluten fria kosten . &lt;br/&gt;&lt;br&gt; Det skulle vara en fördel för många av de screenade barn om riktlinjerna kunda vara samma för alla grupper av barn . Endoskopi kräver narkos, vilket kan innebära en ökad risk exempelvis för barn med Mb Down.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Även metoden för att göra tunntarmsbiopsier har utvecklats. Tidigare var det standardmetoden att använda kapsel, men den metoden innebär att man bara kan bedöma en tarmbit. Det har visat sig att barn kan ha fläckiga förändringar i tarmen och om man bara tar en enda biopsi så kan man missa fall. Fördelen med endoskopi är att man kan ta flera tunntarmsbitar ifrån olika områden av tarmen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Behandlingen av glutenintolerans går ut på att helt utesluta gluten ur maten. I Sverige får man upptill 16 års ålder ekonomisk hjälp, i form av subventionerade glutenfria livsmedel och man ofta även tillgång till dietist kontakt. Följsamheten är beroende av en rad faktorer, såsom ålder vid diagnos och om man har blivit upptäckt via screening. Andra faktorer som påverkar är bristande tillgänglighet på glutenfria alternativ, svårigheter att acceptera smak och konsistens på den glutenfria maten. Gluten är det som ger brödet en fluffig konsistens, vilket gör att glutenfritt bröd ofta är smuligare och hårdare i konsistensen, man kan dock använda surdeg för att förbättra det glutenfria brödet . Ökad kunskap om glutenintolerans hos omgivningen och socialt stöd är faktorer som också stärker följsamheten, vilket är speciellt viktig för ungdomar med glutenintolerans som ofta upplever ofta många praktiska och sociala problem relaterade till den glutenfria kosten. Cafe´livet är utbrett, men sortimentet av glutenfria alternativ är fortfarande relativt begränsat, vilket ev kan bli förbättrat av trenden att äta glutenfritt, utan att man har glutenintolerans.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; DELTAGARE OCH METOD&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ett av syftena med screening studien ETICS (Exploring the Iceberg of Celiacs in Sweden) var att se hur stort mörkertalet var av oupptäckt glutenintolerans bland friska 12 åriga barn , födda både före och efter epidemin. Genom att jämföra två grupper av barn med olika spädbarnkost var det också möjligt att utforska om glutenintolerans kan förebyggas genom att introducera gluten gradvis under pågående amning, eller om det bara medför att insjuknandet senareläggs. ETICS studien var indelad i två etapper(2005-2006, 2009-2010) och utfördes på fem studieorter ; Lund, Växjö, Norrköping, Norrtälje och Umeå . Alla barn i årskurs 6 inbjöds till testning för glutenintolerans genom ett blodprov . Den första etappen omfattade barn födda under toppen av epidemin, 1993, och 10 041 barn inbjudna, varav 7567(75%) barn deltog . Under den andra etappen omfattande barn födda efter epidemin, 1997 , blev 8284 barm inbjudna varav 5712 (69%) deltog. Sammantaget, utgjorde de 18.000 inbjudna barnen 10% av alla barn födda under åren 1993 och 1997. Studien var skolbaserad och forskningssjuksköterskor åkte ut till skolorna för att ta blodproverna i samarbete med skolsköterskorna. De barn som hade förhöjda värden av de serologiska markörerna i blodprovet, kontaktades och fick komma till respektive barnklinik för fortsatt utredning med tunntarmsbiopsi. De lokala rutinerna varierade på studieorterna , vilket gjorde att en del barn fick göra en tunntarmsbiopsi där man använde ett kapselinstrument och en del av barnen fick göra en endoskopisk tunntarmsbiopsi . De barn som hade en tunntarmsbiopsi som blivit bedömd som normal el som inte var bedömbar, fick genomgå ytterliggare en tunntarmsbiopsi, där man enbart använde endoskopi. &lt;br/&gt;&lt;br&gt; I den andra fasen av ETICS studien utfördes alla tunntarmsbiopsier endoskopiskt. Tunntarmsbitarna bedömdes i första hand av patologläkaren på respektive sjukhus och sedan av en expert patolog, som var ovetandes om resultaten. Om bedömningen mellan den lokala och expert patologen inte överensstämde , gjordes ytterliggare en bedömning av en andra expertpatolog. Diagnosen glutenintolerans ställdes genom konsensus av de tre patologernas bedömning.&lt;br/&gt;&lt;br&gt; Följsamheten till den glutenfria kosten bedömdess genom en kombination av frågeformulär där svarsalternativen var följande; alltid, ofta, ibland, sällan eller aldrig och nivån på de serologiska markörerna efter 1 år med glutenfri kost.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; RESULTAT&lt;br/&gt;&lt;br&gt; I screening av barn födda 1993 upptäcktes att 2/3 av alla barnen med celiaki var tidigare oupptäckta. Den totala förekomsten av glutenintolerans i denna åldersgrupp var 3%, vilket är den högsta förekomsten som hittills påvisats i Europa och USA. Glutenintolerans var vanligare bland flickor än pojkar.&lt;br/&gt;&lt;br&gt; Genom att skärpa den diagnostiska processen hittade vi fler fall med glutenintolerans, dels genom att biopsera om alla barn som hade en första normal biopsi, vilket resulterade i att ytterliggare tre barn upptäcktes och även genom att låta en expert patolog bedöma alla tunntarmsbitarna, vilket resulterade i att 5 barn fick diagnosen glutenintolerans. &lt;br/&gt;&lt;br&gt; Av de barn som hade tarmbitar som var bedömbara ifrån olika delar av tarmen var det 9% som hade fläckig utbredning av tarmskadan.&lt;br/&gt;&lt;br&gt; När vi jämförde korrelationen mellan nivån på de serologiska markörerna med graden av tarmskada , fann vi att alla barn som hade 10 ggr över de normala nivåerna också hade en högre grad av tarmskada. Om ESPGHANs riktlinjer även gällde för screenade barn, skulle de innebära att 25% av barnen inte skulle ha behövt genomgå en tunntarmsbiopsi för att erhålla diagnos. Det har tidigare rapporterats att följsamheten till den gluten fria kosten kan påverkas negativt om man har blivit upptäckt via screening och även att bli diagnosticerad som tonåring. Det visade sig dock att följsamheten till den glutenfria kosten var hög (75%) bland de screening upptäckta ungdomarna. Majoriteten (82%) svarade i enkäten att de alltid åt glutenfri kost, vilket överrenstämde med att de serologiska värdena hade normaliserats. Det fanns dock en liten grupp som svarade att de alltid följde den glutenfria kosten, men som inte normaliserade värde efter ett år med glutenfri kost.Det var dock så att majoriteten (85%) av dessa barn hade höga värden initialt och deras värde halverades efter 1 år. Bland barnen som rapporterade att de oftast följde den glutenfria kosten hade de flesta av barnen normaliserade värde, medan de barn som rapporterade att de bara följde den gluten fria kosten ibland, hade förhöjda värden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; SLUTSATSER&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Glutenintolerans är vanligare bland barn än vad som tidigare var känt och majoriteten av fallen är odiagnosticerade. Varje steg i den diagnostiska processen är av betydelse för hur många fall med glutenintolerans man hittar. Genom att skärpa den diagnostiska processen, med att utföra ytterliggare en biopsi i oklara fall och att låta en expert patolog bedöma tunntarmsbitarna, hittar man ytterliggare fler fall med glutenintolerans.&lt;br/&gt;&lt;br&gt; Enligt ESPGHANs rekommendationer, där man inte behöver göra en tunntarmsbiopsi på barn med höga värden av de serologiska markörerna, verkar överensstämma även på screening upptäckta barn. Detta fynd gör att man behöver ifrågasätta huruvida kriterierna för ställa gluten intolerans diagnos bör ändras för de screenade barnen.&lt;br/&gt;&lt;br&gt; Följsamheten till den glutenfria kosten var hög även hos ungdomar som var screening upptäckta, vilket kan ha påverkats av många faktorer, såsom subventionerade glutenfria livsmedel och god tillgång till dietist. Uppföljningen var dock efter endast ett år, och det krävs fler studier för att värdera om följsamheten kvarstår efter en längre tids behandling med glutenfri kost.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e8a9ce13-f73f-4653-8418-1d09ec32fd57</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Charlotta_Webb.pdf">https://portal.research.lu.se/files/3163963/4728998.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4866496</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Paediatrics, Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Celiac disease</topic> <topic>screening</topic> <topic>prevalence</topic> <topic>small-bowel biopsy</topic> <topic>enteropathy</topic> <topic>transglutaminase</topic> <topic>gluten-free diet</topic> <topic>adherence</topic> </subject> <subject authority="lup"> <topic>Pediatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-046-3</identifier> <identifier type="oldLupId">4728935</identifier> <part> <detail type="volume"> <number>2014:117</number> </detail> <extent unit="pages"> <total>74</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-07T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>e8a9ce13-f73f-4653-8418-1d09ec32fd57</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:30+02:00</recordDateApproved> </recordInfo> </mods>

Telomeres play a key role in chromosome stability and regulation of the cellular lifespan. Telomeres are shortened during cell division, and probably, by not yet well characterised factors in the environment. Short telomeres in peripheral blood have repeatedly been associated with increased risk of various types of cancer, as well as with cardiovascular diseases, diabetes, and lung diseases. The aim of this thesis was to explore the effect of exposures on telomere length in different occupational or environmental settings, and also to investigate the association between telomere length and chromosomal aberrations in blood, a biomarker for cancer risk. Different study populations were recruited to elucidate specific hypothesises: In the first study 157 workers in rubber industry were recruited to investigate the effect of exposure to rubber fumes on telomere length; in the second study 101 welders, 34 diesel-exposed workers and 127 controls were examined to elucidate the effect of exposure to particles on telomere length; in the third study 202 women exposed to arsenic via drinking water were analysed for effects of arsenic exposure on telomere length; and finally, in the fourth study 364 male adults were recruited to study the association between telomere length and chromosomal instability. Associations between exposures and telomere length were found: N-nitrosamines were related to shorter telomeres, whereas welding fumes and diesel exhaust showed no significant impact on telomere length. Arsenic in drinking water was related to longer telomeres and the association between arsenic and telomere length was modified by polymorphisms in the main arsenic-metabolizing gene. Although telomere length was associated with chromosome instability, no significant association was found between telomere length and cancer risk in our study, probably due to the limited number of cancer cases. We also found effects of exposure on methylation of DNA, and in turn with chromosome instability, reflecting interactions of the environment with epigenetic processes. The findings of the thesis provide evidence that some exposures, at workplaces or in the general environment, influence the average telomere length in peripheral blood. Since telomeres are key components for genomic stability and often altered during malignant transformation, it is likely that the effect of the exposures on telomeres found here reflect a mechanism of carcinogenesis for the compounds studied.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d531185d-0bc7-452a-97d8-ca02401a8bb0</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="64453_Huiqi_L_3.pdf">https://portal.research.lu.se/files/3164324/4251449.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2106852</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>exposure</topic> <topic>telomere</topic> <topic>methylation</topic> <topic>chromosomal aberration</topic> <topic>cancer risk</topic> <topic>rubber fumes</topic> <topic>arsenic</topic> <topic>welding fumes</topic> <topic>diesel exhaust</topic> <topic>particulate matter</topic> </subject> <subject authority="lup"> <topic>Occupational Health and Environmental Health</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-41-0</identifier> <identifier type="oldLupId">4228606</identifier> <part> <detail type="volume"> <number>2014:17</number> </detail> <extent unit="pages"> <total>126</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-02-14T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>d531185d-0bc7-452a-97d8-ca02401a8bb0</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:34+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:34+02:00</recordDateApproved> </recordInfo> </mods>

A good hemostasis is mandatory during a thyroid operation and many new devices have been available during the last two decades. Total thyroidectomy, (TT) is now by many surgeons considered the method of choice when treating Graves´ disease (GD) and multinodular goitres (MNG) surgically. Hypocalcaemia is the most common adverse event after thyroid surgery and the reported frequency ranges from 4-55 %. It is difficult to identify and predict patients at risk for developing postoperative hypocalcaemia. Previously described risk factors for transient hypocalcaemia are extent of surgery, lymph node dissection, GD, bone hunger and the number of parathyroid glands identified peroperatively and parathyroid autotransplantation. &lt;br/&gt;&lt;br&gt; Aims: To compare two different operation techniques for patients with GD undergoing TT and the risk of hypocalcaemia after TT for patients with MNG and GD, respectively. To identify risk factors for postoperative hypocalcaemia after TT in patients with GD and to predict risk factors for permanent hypocalcaemia after TT. Methods: In Paper I we compared in a prospective randomised controlled trial, a conventional operation technique vs. ultracision (Harmonic Scalpel(HS)) when performing TT. In Paper II, we compared the risk for hypocalcaemia between patients with GD and MNG undergoing TT. In Paper III, data were extracted from the Scandinavian Quality Register for Thyroid and Parathyroid Surgery (SQRTP) and patients with GD undergoing TT during year 2004 – 2008 in 23 surgical departments in Sweden were studied. In Paper IV, risk factors of permanent hypoparathyroidism after TT from a prospective database at the same surgical department was analysed. &lt;br/&gt;&lt;br&gt; Results: 27 patients were randomised to the HS group and 24 patients to the conventional group (knot tying). Operation time was significantly shorter in the HS group (I). Patients with GD (n=129) were younger than patients with MNG (n=81). Symptoms of hypocalcaemia were more common in patients with GD but there were no other differences between the two groups (II). Risk factors for i.v. calcium after TT in patients with Graves´ disease were low hospital volume, operative time, university hospital and reoperation due to postoperative hematoma. Risk factors for treatment with vitamin D at discharge increased with operative time, weight of the specimen, parathyroid autotransplantation and reoperation. Risk factors for treatment with vitamin D at first follow up at 6 weeks were weight of the specimen, preoperative treatment with beta blockers. At 6 months follow up, risk factors for treatment with vitamin D were weight of the specimen and reoperation (III). There were 519 patients, median follow up (range) was 2.7 years (1.2 – 10.3). The rate of permanent hypoparathyroidism was 1.9 %. Parathyroid autotransplantation was performed in 90/519, 17.3 % and none of these developed permanent hypoparathyroidism, as did no patient with normal PTH level on day one postoperatively. &lt;br/&gt;&lt;br&gt; Conclusion: Patients with GD undergoing TT performed with Harmonic Scalpel® had a significantly shorter operation time, without an increased risk for complications. Patients with GD were younger and experienced more often symptoms of hypocalcaemia after TT compared to patients with goitres, but there were no biochemical differences. Risk factors for medically treated hypocalcaemia after TT in patients with Graves´ disease are multifactorial and vary over follow-up time. A low PTH level early after TT is associated with a high risk of permanent hypoparathyroidism. Normal levels of PTH postoperatively exclude long term hypoparathyroidism. Parathyroid autotransplantation seems to be warranted as a way of minimizing the risk of permanent hypoparathyroidism</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; POPULÄRVETENSKAPLIG SAMMANFATTNING&lt;br/&gt;&lt;br&gt; Dokumentation om Sjukdomar i sköldkörteln (thyroidea) finns dokumenterade i litteraturen sedan nästan 3000 år tillbaka. Många miljoner människor över hela världen lider av någon typ av sköldkörtelsjukdom, t.ex. förstorad sköldkörtel (struma/goiter), elakartade -, godartade förändringar eller överaktiv körtel (hyperthyreos, Graves’ sjukdom). Vissa sjukdomar kan behandlas med läkemedel medan andra behandlas mest effektivt med kirurgiska ingrepp. Sköldkörteln producerar viktiga hormoner som kallas tyroxin (T4) och trijodidtrionin (T3) som reglerar kroppens ämnesomsättning, det vill säga hur kroppen utvinner energi ur födan. Om din sköldkörtel inte fungerar normalt då använder kroppen energin långsammare eller snabbare än normalt. Total thyroidektomi (TT, borttagande av hela sköldkörteln) pga. hyperthyreos uppfattas av de flesta/många kirurger som den svåraste av sköldkörteloperationer. som genomförs vid sköldkörtels kirurgi, och många anser att risken för komplikationer som skada på stämbandsnerven, blödningar och sänkt kalcium (hypokalcemi) efter operation, är ökad. Hypertyreosis (Graves´ sjukdom) kan även behandlas med läkemedel (tyreostatika) och radiojod behandling, men risken är att sjukdomen kan komma tillbaka. Vid svårare fall av hypertyreosis, läggs även till betablockerare och kortison för att få bättre kontroll över sjukdomen. Principen för radiojodbehandling är att utnyttja sköldkörtelns förmåga att ta upp och lagra jod. Tyreostatika minskar produktionen av sköldkörtelhormonerna tyroxin, T4, och trijodtyronin, T3, i sköldkörteln. Höga doser av läkemedlet kan helt stoppa produktionen av sköldkörtelhormon. Radioaktiv form av jod (I-131) ges, som ansamlas i körtelvävnaden och i denna avger strålning med mycket kort räckvidd. Sköldkörteln är ett synnerligen kärlrikt vaskuliserad organ och därför viktigt att åstadkomma noggrann blodstillnings under operationen: Det kan uppnås med att ligera kärl med suturtråd. Med noggrann blodstillning blir det också lättare att identifiera bisköldkörtelar (producera parathyroidea hormon, PTH, som styr kalcium i kroppen) och stämbandsnerv. Komplikationer till sköldkörtelkirurgi är generellt relativt sällsynta men kan vara dyra för samhället. Hypokacalcemi är den vanligaste komplikationen till total thyroidektomi, som kan ge symtom bl.a. i form av stickningar i fingrar och runt munnen men i mer avancerade former kan det leda till kramp. Därför är det viktigt att försöka identifiera de riskfaktorer som ger ökad risk för komplikationer vid thyroidea kirurgi, både övergående och permanenta. &lt;br/&gt;&lt;br&gt; I den första studien i denna avhandling jämfördes skillnad mellan två olika operationstekniker vid TT hos patienter med Graves’ sjukdom. I den ena gruppen användes den konventionella tekniken som innebär ligaturer och diatermi för att uppnå hemostas, och i den andra gruppen användes ultraljudskniv (Harmonic Scalpel®, HS) som delar kärl med vibration vilket stänger tillkärlen samtidigt. Vi fann en signifikant kortare operation tid i HS-gruppen, vilket stämmer bra överens med övriga studier. &lt;br/&gt;&lt;br&gt; Många kirurger anser att risken för komplikationer vid TT hos patienter med Graves’ är högre jämfört med andra thyroidea diagnoser. I den andra studien i avhandlingen jämförde vi två olika patient grupper, en grupp med multinodös struma och en grupp med Graves´ sjukdom, som båda genomgick TT. Våra resultat kunde inte visa någon signifikant skillnad vad gäller risk för komplikationer mellan grupperna. Yngre patienter (Graves ´ patienter) upplevde mer symtom av hypokalcemi (stickningar och domningar) men det var ingen signifikant skillnad i blodprover. Detta är delvis överens med övriga studier, men flesta visar dock ökad risk för utveckling av postoperativa komplikationer som hypokalcemi efter TT hos Graves´ patienter. &lt;br/&gt;&lt;br&gt; I den tredje studien försökte vi att identifiera riskfaktorer hos Graves´ patienter för symtomatisk hypokalcemi som kräver medicinsk behandling med kalcium och/eller D-vitamin. Patienter som opererats på grund av Graves&apos; sjukdom är registrerade i det skandinaviska kvalitetsregistret för tyroidea - och parathyroideakirurgi, därifrån data hämtades för att försöka identifiera risk faktorer för hypokalcemi. Vi fann att Graves´ patienter som förbehandlas med beta blockare inför kirurgi, hade en ökad risk för behandlingskrävande hypokalcemi vid första uppföljningen, efter ca 6 veckor. Reoperation och högre preparatvikt var risk faktorer för behov av behandling med vitamin D vid 6 månaders uppföljning. I vårt sista det fjärde arbetet undersökte vi riskfaktorer för permanent hypokalcemi bland patienter som opererats vid Lunds Universitet Sjukhus. I denna studie fann vi att lågt eller omätbart PTH &lt;br/&gt;&lt;br&gt; tidigt efter operation är en risk faktor för långdragen eller permanent hypokalcemi, och att inplantera bisköldkörtels vävnad under operation kan eventuellt undvika permanenta hypokalcemi.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8646ced0-c58f-4b8d-a69d-a552010fc18c</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Palles_avh_e_spik.pdf">https://portal.research.lu.se/files/3165038/4451434.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2296233</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Surgery, Clinical Sciences Lund, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Total thyroidectomy</topic> <topic>Graves´ disease</topic> <topic>multinodular goitre</topic> <topic>transient hypocalcaemia</topic> <topic>permanent hypocalcaemia</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-89-2</identifier> <identifier type="oldLupId">4448266</identifier> <part> <detail type="volume"> <number>2014:63</number> </detail> <extent unit="pages"> <total>125</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-14T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>8646ced0-c58f-4b8d-a69d-a552010fc18c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:40+02:00</recordDateApproved> </recordInfo> </mods>

The etiology is unknown and the pathogenesis has not been fully elucidated. Impairments of the immune system and of the mechanisms regulating cell death are commonly seen in SLE patients. Autoantibodies, in particular anti-dsDNA antibodies, are considered hallmarks of SLE, but the ideal biomarker for SLE is still missing. &lt;br/&gt;&lt;br&gt; In this thesis, I summarize the state of the art about biomarkers for SLE and present four original papers, resulting from two different investigations that focused on traditional and novel biomarkers for SLE. &lt;br/&gt;&lt;br&gt; The first study concerns the evaluation of anti-dsDNA antibodies as diagnostic and prognostic biomarkers in a realistic clinic scenario. We designed a multicentre study for recruitment and clinical investigation of patients with recent onset of rheumatic symptoms. In paper I, we present the results showing the presence of anti-dsDNA antibodies in many non-SLE patients, with inconsistent results of the assay simultaneously performed in different laboratories. The positivity of the test is found also in about one fourth of ANA negative patients and poses little risk of developing SLE within 5 years, in contrast to previous data. Paper II is a report of results showing that presence of anti-dsDNA antibodies, independently of the assay used, is significantly associated with glomerulonephritis and pleuritis, regardless of the diagnosis. The positivity confirmed by two different methods tends also to cluster with hematological manifestations. We suggest that anti-dsDNA antibodies should be used as biomarkers of certain clinical phenotypes, regardless of the diagnosis. &lt;br/&gt;&lt;br&gt; The second part of this thesis concerns the assessment of novel promising biomarkers for SLE. We designed a longitudinal investigation, where patients with established SLE were followed for about two years, with regular clinical and laboratory assessments every other month. I aimed at studying the chronological relationships between the presence of clinical manifestations of SLE and the positivity of the investigated potential biomarkers, namely PNC assay, osteopontin and S100A8/A9.&lt;br/&gt;&lt;br&gt; In paper III, the PNC assay is presented as a specific and reliable supplementary laboratory tool in the management of SLE patients. It is a functional test displaying the ability of polymorphonuclear cells to engulf necrotic cell material, which resembles the so-called LE-cell phenomenon. In combination with positivity of other traditional biomarkers, PNC assay may predict important clinical features, herein glomerulonephritis. &lt;br/&gt;&lt;br&gt; In paper IV, similar analyses have been performed focusing on osteopontin and S100A8/A9, two pleiotropic proteins that interplay with key mechanisms involved in the pathogenesis of SLE. Their assessment may provide the clinician with important information about the odds of current or upcoming increased disease activity in SLE patients, more specifically clinical features such as arthritis, mucocutaneous manifestations and, above all, glomerulonephritis. The two proteins show weak correlation and low agreement of results, suggesting that their increased levels probably mirror involvement in different pathogenic mechanisms. &lt;br/&gt;&lt;br&gt; The results of the present research project contribute to more accurate diagnostic process in patients with recent onset of undiagnosed rheumatic symptoms and more efficient management of patients with established SLE. Being the optimal biomarker still missing, a composite panel of reliable biomarkers may provide the clinician with a tangible support to the clinical acumen.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9f96ac90-27b2-46e4-a3b8-bad4f54e790b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Studies_on_anti-dsDNA_antibodies_and_other_potential_biomarkers_in_Systemic_Lupus_Erythematosus.pdf">https://portal.research.lu.se/files/3165094/5364274.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5596715</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Rheumatology, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Systemic Lupus Erythematosus Anti-dsDNA antibodies Biomarkers Osteopontin S100A8/A9 LE-cells Diagnostic accuracy Longitudinal study Multicentre study</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-132-3</identifier> <identifier type="oldLupId">5364271</identifier> <part> <detail type="volume"> <number>2015:53</number> </detail> <extent unit="pages"> <total>160</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-22T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>9f96ac90-27b2-46e4-a3b8-bad4f54e790b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:06:42+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:06:42+02:00</recordDateApproved> </recordInfo> </mods>

General practitioners’ (GPs’) attitudes and adherence to evidence-based treatment guidelines might be influenced by different interventions and need to be studied. &lt;br/&gt;&lt;br&gt; Objectives: 1. To study different intervention models that might influence GPs’ adherence to treatment guidelines. 2. To describe GPs’ attitudes towards locally developed treatment guidelines.&lt;br/&gt;&lt;br&gt; Methods: (Paper I) Systematic medication reviews by pharmacists were performed in a randomised controlled study of 369 elderly patients living in the community or nursing homes, who were using the multi-dose drug dispensing (MDD) system. Drug lists were assessed before and after the intervention with a focus on potentially inappropriate medications (PIMs). (Paper II) A retrospective analysis of medication lists was conducted in the same patient sample, with a focus on fall risk-increasing drugs (FRIDs), orthostatic drugs (ODs) and falls. (Paper III) A randomised controlled study was performed using two questionnaire-based behaviour change interventions aimed at reducing prescription of antibiotics against URTIs in primary care. (Paper IV) A qualitative study was performed using focus group interviews to assess GPs’ attitudes towards evidence-based local treatment guidelines.&lt;br/&gt;&lt;br&gt; Results: Papers I and II: Systematic medication reviews by pharmacists reduced the number of patients taking PIMs and the total number of drugs these patients were taking, but not the number of patients taking more than three psychotropic drugs. A significant proportion (87%) of the study sample was taking FRIDs and ODs. Numbers of FRIDs were associated with the total number of drugs and with severe falls. There was no association between numbers of ODs and occurrence of severe falls. Paper III: There was a significant decrease in the antibiotic prescribing rate in one of the two intervention groups compared to the control group in patients 0-6 years, but no differences between the groups in patients of all ages. Paper IV: Trust in evidence-based recommendations and patient safety were found to be key factors in prescribing, as was the patient-doctor encounter, with emphasis on informing the patient. The GPs all experienced a lack of time to self-inform, difficulties managing patients with multiple prescribers and direct-to-consumer drug industry information. Cost containment was perceived as both a barrier and a motivator for adherence to guidelines.&lt;br/&gt;&lt;br&gt; Conclusion: Multi-professional assessment of patient’s drug list and questionnaire-based behaviour change interventions might be feasible methods to improve quality of drug treatment in primary care and need to be studied further. GPs found trust in evidence-based guidelines and patient safety to be essential in drug prescribing.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bakgrund: Förskrivning av läkemedel är en av de vanligaste medicinska åtgärderna men samtidigt den största orsaken till patientskador och patientsäkerhetsproblem i Sverige. Läkemedelsbehandling av multisjuka äldre och förskrivning av antibiotika mot okomplicerade luftvägsinfektioner är två områden där patientsäkerhetsproblem har uppmärksammats. Behandling med potentiellt olämpliga läkemedel av äldre sköra patienter kan leda till problem som läkemedelsinteraktioner, fall, onödiga sjukhusinläggningar, ökad morbiditet och mortalitet i den här patientpopulationen. Felaktig förskrivning av antibiotika kan resultera i ökad förekomst och spridning av resistenta bakterier. Behandlingsrekommendationer på både nationell och lokal nivå utformas årligen för att optimera läkemedelsförskrivningen på dessa två områden. För att förbättra följsamhet till behandlingsrekommendationer är det viktigt att utforska allmänläkares attityder gentemot dessa rekommendationer. &lt;br/&gt;&lt;br&gt; Syfte: Det övergripande syftet med avhandlingen är att studera olika åtgärder som kan optimera läkemedelsbehandlingen av äldre multisjuka patienter och antibiotikaförskrivningen i primärvården samt att beskriva allmänläkarnas attityder gentemot lokala behandlingsrekommendationer.&lt;br/&gt;&lt;br&gt; Metod: (Studie I) Apotekarledda läkemedelsgenomgångar utfördes för 369 multisjuka patienter, 75 år och äldre, boende i egna hem med hjälp av hemsjukvård eller på särskilda boenden och som använde dosdispenserade läkemedel. Data från läkemedelslistor insamlades före och efter läkemedelsgenomgångar med fokus på potentiellt olämpliga läkemedel. &lt;br/&gt;&lt;br&gt; (Studie II) En retrospektiv analys av läkemedelslistorna utfördes på samma patienter som medverkade i studie I. Fokus i studie II var fallriskhöjande läkemedel, ortostatiska läkemedel och fall. &lt;br/&gt;&lt;br&gt; (Studie III) En randomiserad kontrollerad studie genomfördes med två frågeformulär utformade enligt kognitiva beteendeteorier i syfte att minska antibiotikaförskrivningen mot okomplicerade luftvägsinfektioner i primärvården. (Studie IV) En kvalitativ studie med fokusgrupper genomfördes för att studera allmänläkarnas attityder gentemot evidensbaserade lokala behandlingsrekommendationer.&lt;br/&gt;&lt;br&gt; Resultat: Studie I och II: Apotekarledda läkemedelsgenomgångar ledde till en minskning av antalet patienter som använde potentiellt olämpliga läkemedel, en minskning av totalantalet läkemedel som dessa patienter använde, men inte av antalet patienter som använde fler än tre psykofarmaka. En stor andel (87 %) av dessa patienter använde fallriskhöjande läkemedel och ortostatiska läkemedel. Det fanns samband mellan antalet fallriskhöjande läkemedel, totalantalet läkemedel och allvarliga fall. Det fanns inget samband mellan antalet ortostatiska läkemedel och allvarliga fall. &lt;br/&gt;&lt;br&gt; Studie III: Det blev en signifikant minskning i antalet antibiotikarecept per 1000 listade patienter hos patienter mellan 0-6 år, men ingen skillnad mellan interventionsgruppen och kontrollgruppen hos patienter av alla åldrar. &lt;br/&gt;&lt;br&gt; Studie IV: Tillit till evidensbaserade rekommendationer och patientsäkerhet var nyckelfaktorer i läkemedelsförskrivningen, såsom mötet mellan läkare och patient, med fokus på patientinformationen. Alla intervjuade allmänläkare upplevde brist på tid för att informera sig, svårigheter att hantera patienter med läkemedelslistor från flera förskrivare och läkemedelsreklam riktad direkt till allmänheten. Ekonomiska styrmedel upplevdes vara både en barriär och en motiverande faktor vad gäller följsamhet till behandlingsrekommendationer.&lt;br/&gt;&lt;br&gt; Slutsatser: Avhandlingen visar att tvärprofessionella läkemedelsgenomgångar och interventioner baserade på kognitiva beteendeteorier kan vara fungerande metoder för att optimera kvalitén av läkemedelsbehandlingen i primärvården. &lt;br/&gt;&lt;br&gt; Allmänläkare tycker att tillit till evidensbaserade rekommendationer och patientsäkerhet är nyckelfaktorer som påverkar följsamheten till behandlings-rekommendationer i primärvården.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8c25adeb-21ab-44aa-977c-865464fa29bc</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Veronica_Milos_Nymberg.pdf">https://portal.research.lu.se/files/3167084/4729592.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3257884</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Family Medicine</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Drug therapy</topic> <topic>elderly</topic> <topic>guidelines</topic> <topic>primary care</topic> <topic>potentially inappropriate medications</topic> <topic>fall risk increasing drugs</topic> <topic>antibiotics</topic> <topic>upper respiratory tract infections</topic> <topic>attitudes</topic> <topic>adherence</topic> <topic>general practitioners</topic> <topic>Sweden</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-016-6</identifier> <identifier type="oldLupId">4729585</identifier> <part> <detail type="volume"> <number>2014:87</number> </detail> <extent unit="pages"> <total>84</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-21T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>8c25adeb-21ab-44aa-977c-865464fa29bc</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:07:13+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-29T01:01:17Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:07:13+02:00</recordDateApproved> </recordInfo> </mods>

Evidence is presented for a fatty acid amide hydrolase (FAAH)-dependent fatty acid conjugation of p-aminophenol, a known acetaminophen metabolite, to form the potent TRPV1 activator AM404 in the central nervous system. We show that acetaminophen is able to reduce the content of prostanoids in brain and kidney, but this effect is independent of FAAH. While ibuprofen produces a similar reduction as acetaminophen of the PGE2 level in brain, only acetaminophen displays antinociceptive activity in animal tests of acute non-inflammatory pain, indicating that other mechanisms than central cyclooxygenase inhibition must be sought to explain the analgesic effect of acetaminophen in these tests. Knowledge of the mechanisms of action of acetaminophen may help to develop analogs with improved analgesic activity. Many TRP ion channels, including TRPV1, are regulated by PLC-coupled surface receptors. After PLC-dependent cleavage of phosphatidylinositol bisphosphate into diacylglycerol (DAG) and inositoltrisphosphate, diacylglycerol may be further metabolized to monoacyl-glycerols, such as 2-arachidonoylglycerol (2-AG) and 2-oleoylglycerol by the action of DAG lipase. 2-Arachidonoylglycerol and 1-AG activate both native TRPV1 on sensory nerve fibers in rodent mesenteric arteries and heterologously expressed rat and human TRPV1. The effects of 2-AG and the metabolically stable analog noladin ether were almost absent in TRPV1 gene-deficient mice. Stimulation of isolated rat dorsal root ganglia with the inflammatory mediators bradykinin and ATP led to an increase in the level of 2-AG, whereas the levels of anandamide and 2-oleoylglycerol were unaffected. Extensive metabolism of d8-2-AG and d5-1-AG, in contrast to d8-anandamide, was demonstrated in homogenates of rat mesenteric arteries. The monoacylglycerol lipase inhibitor MAFP prevented the metabolism of these lipids and enhanced the TRPV1-mediated vascular effects of 2-AG and 1-AG, but not anandamide. The existence of a regulated biosynthesis and enzymatic degradation of 2-AG and 1-AG in TRPV1-containing tissues is compatible with a physiological role for these monoacylglycerols as messengers in the PLC/TRPV1 signaling cascade. Bioactive lipids, with TRPV1 activity, can be formed via drug metabolism and after stimulation of PLC-coupled surface receptors.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8c33608b-3241-4b85-99ab-11f3ddec30c3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kopia_av_centrerad_Bioactive_lipids_in_nociception_bilder.pdf">https://portal.research.lu.se/files/3167108/1222517.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1071583</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Clinical Chemistry and Pharmacology, Dept of Laboratory Medicine</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Cannabinoids</topic> <topic>Anandamide</topic> <topic>AM404</topic> <topic>2-Arachidonoylglycerol</topic> <topic>Acetaminophen</topic> <topic>Cyclooxygenase</topic> <topic>Nocicieption</topic> <topic>TRPV1</topic> </subject> <subject authority="lup"> <topic>Medical and Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-49-1</identifier> <identifier type="oldLupId">1222478</identifier> <part> <detail type="volume"> <number>2008:96</number> </detail> <extent unit="pages"> <total>153</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-09-20T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>8c33608b-3241-4b85-99ab-11f3ddec30c3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:07:13+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:07:13+02:00</recordDateApproved> </recordInfo> </mods>

Ruptured&lt;br/&gt;&lt;br&gt; abdominal aortic aneurysm (rAAA) is a painful and serious predicament with a mortality of 80-90%. Half of the patients die before&lt;br/&gt;&lt;br&gt; arriving to hospital, leaving family members in sorrow and shock. In Sweden about 700-1000 patients die each year due to rAAA,&lt;br/&gt;&lt;br&gt; corresponding to 1.5% of all deaths in men. &lt;br/&gt;&lt;br&gt; Four randomized trials have shown that screening for AAA is cost-effective to reduce both AAA related mortality by 50% and all-cause&lt;br/&gt;&lt;br&gt; mortality by 3%. These trials have been the reason why screening 65 year-old-men for AAA has been introduced in Sweden.&lt;br/&gt;&lt;br&gt; In this thesis we evaluated different aspects on screening for AAA. &lt;br/&gt;&lt;br&gt; Study I; the aim was to study whether a biological marker (APC PCI complex) may be used as a screening marker for AAA in patients&lt;br/&gt;&lt;br&gt; with peripheral vascular disease without previously known AAA. However, the sensitivity and specificity were both to weak to be used as&lt;br/&gt;&lt;br&gt; a screening marker for AAA in the clinical praxis. Nevertheless, we discovered that the prevalence of AAA was 13% in patients with&lt;br/&gt;&lt;br&gt; peripheral vascular disease. &lt;br/&gt;&lt;br&gt; Study II; the aim was to investigate the impact of socioeconomic status (SES) and demographical aspects on compliance to AAA-&lt;br/&gt;&lt;br&gt; screening and also to evaluate the associations between AAA prevalence and SES. Our results indicated that the prevalence of AAA is&lt;br/&gt;&lt;br&gt; higher in demographic areas with lower SES. The compliance to AAA-screening was also lower in areas with lower SES.&lt;br/&gt;&lt;br&gt; Study III; the aim was to investigate if a collaboration between a professional advertising agency and an academic vascular unit can&lt;br/&gt;&lt;br&gt; result in increased compliance to AAA screening. The results showed that compliance to AAA-screening can be increased significantly&lt;br/&gt;&lt;br&gt; by consulting an advertisng agency. &lt;br/&gt;&lt;br&gt; Study III; the aim was to evaluate if screening is still cost-effectivley in the new era of decreased AAA prevalence, EVAR as the&lt;br/&gt;&lt;br&gt; predominant treatment method and improved medical treatment. By using a Markov model we could show that it is still cost-effective&lt;br/&gt;&lt;br&gt; to screen for AAA even with the aformentioned changes. &lt;br/&gt;&lt;br&gt; In conclusion; Screening for AAA seems justified in the new era of changing prerequisites. However, importance of SES and different&lt;br/&gt;&lt;br&gt; aspects on improving AAA compliance are of great importance and need to be studied further.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Populärvetenskaplig sammanfattning på svenska (Comprehensive summary in Swedish)&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Stora kroppspulsådern är det centrala kärl som från hjärtat leder blodet vidare till kroppens alla organ. När kroppspulsåderns kärlvägg försvagas resulterar detta i en utvidgning (bråck). Ett kroppspulsåderbråck sitter vanligtvis i nivå med naveln, strax nedom kärlen som försörjer njurarna. Förekomsten av kroppspulsåderbråck är 1.8% hos 65 åriga män. Män drabbas 4-6 gånger oftare jämfört med kvinnor. Med tiden kan bråcket bli större vilket ökar risken för att det spricker, ledande till att blodet som pumpats ut ifrån hjärtat istället rinner utanför kärlet ut i bukhålan. Ofta är den drabbade helt ovetande om sjukdomen som vanligtvis inte ger symtom förrän bråcket spricker. Då detta sker dör nästan 50% innan de kommer till sjukhuset, och endast 33% kan genomgå kirurgi. Totalt är dödligheten vid sådan händelse 80-90%. Fyra stora studier har kunnat visa att man kan halvera dödligheten i spruckna pulsåderbråck genom att med hjälp av ultraljud screena 65 åriga män och operera bråck över en viss storlek i förebyggande syfte. På denna indikation har man introducerat screening av stora kroppspulsådern hos alla 65 åriga män i Sverige.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Denna avhandling har studerat olika aspekter av screening för kroppspulsåderbråck.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie I: Syftet var att studera om en biologisk markör i blodet (APC-PCI komplex) kan användas för att med hjälp av ett blodprov kunna screena för kroppspulsåderbråck hos patienter med kärlsjukdom inom andra kärlområden men utan känt kroppspulsåderbråck. Studien visade att det inte gick att använda denna markör eftersom dess känslighet var otillräcklig. Däremot upptäckte vi att förekomsten av kroppspulsåderbråck var hög (13%) hos en sedan tidigare kärlsjuk population.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie II: Syftet var att kartlägga hur hörsamheten till screening och förekomsten av kroppspulsåderbråck påverkades av olika socioekonomiska faktorer. Vi upptäckte att hörsamheten till screening varierade stort beroende på i vilket geografiskt område männen bodde. Vi noterade att områdena med lägst hörsamhet till screening hade högre förekomst av invandrare, lägre utbildning och högre arbetslöshet. Förekomsten av kroppspulsåderbråck var även högre i de områdena där hörsamheten var som lägst. Med andra ord; de patienter som löpte störst risk att vara sjuka kom inte till vår undersökning.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie III: Syftet var att försöka förbättra hörsamheten i de områdena där denna var som lägst. Detta gjorde vi genom att samarbeta med en professionell reklambyrå. Reklamfirman tog fram en förbättrad kallelse till männen som genomgått språklig redigering, fått ändrad layout, samt kompletterats med karta med vägbeskrivning ifrån deras hem till vår screeninglokal samt en röd slips knuten som ett kroppspulsåderbråck. Resultatet var att hörsamheten ökade märkbart i de områdena där vi använde materialet från reklamfirman.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie IV: Syftet var att med hjälp av datasimulering utvärdera om det fortfarande är kostnadseffektivt att screena 65 åriga män för kroppspulsåderbråck när förutsättningarna har ändrats. De nya förutsättningarna vi ville undersöka var den lägre förekomsten av kroppspulsåderbråck, det faktum att majoriteten av kirurgin görs med hjälp av kateterburen protesinläggning i aorta samt att alla patienter erhåller sekundärpreventiv medicinering. Undersökningen visade att det fortfarande är kostnadseffektivt att screena 65 åriga män för kroppspulsåderbråck.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/be8f4d84-0f7f-4bbb-925f-6104c54616cf</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Moncef_draft_1_.pdf">https://portal.research.lu.se/files/3167242/7852807.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3375769</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Unit for Clinical Vascular Disease Research</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Abdominal aortic aneurysm</topic> <topic>screening</topic> <topic>biomarkers</topic> <topic>socioeconomic status</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-158-3</identifier> <identifier type="oldLupId">7791549</identifier> <part> <detail type="volume"> <number>2015:79</number> </detail> <extent unit="pages"> <total>79</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-09-18T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>be8f4d84-0f7f-4bbb-925f-6104c54616cf</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:07:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-03-17T05:51:50Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:07:16+02:00</recordDateApproved> </recordInfo> </mods>

The vision covers scenarios in the home, at work, and out in the street, and builds on the ongoing development towards an increasing number of embedded computers with network connectivity.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The thesis presents the assembly as a lightweight mechanism for combination of devices and services in pervasive computing environments. The assembly is intended to be modifiable by an end user, and to facilitate ad-hoc combinations of services as well as adaptations to changes in services. It does so by separating configuration and coordination, specified in an assembly descriptor, from computation, specified in the services. It supports end-user understanding by using service descriptions that can be inspected and interacted with directly through rendered user interfaces. This gives more flexibility than approaches based on domain-level standardization. An assembly can give rise to services of its own, referred to as synthesized services. The synthesized services can be used by other assemblies in turn, for dealing with complex systems in a hierarchical way.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Assemblies and services are elements of the open architecture developed in the project PalCom, and are supported by its communication and discovery protocols. The protocols target resource-constrained devices and situations with varying network connectivity, as required in several of the scenarios studied in PalCom, and they presume no central infrastructure. A central mechanism is the Pacemaker Protocol, which lets devices become aware of each other, using a heartbeat frequency that can be controlled at the application level.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A language for assembly descriptors has been defined, tools have been developed, and frameworks and middleware have been implemented for the developer of PalCom services. These have been used by PalCom partners when building prototypes for scenarios, studied in cooperation with prospective end users in the fields of emergency response, landscape architecture, neonatology, and physical-functional and cognitive rehabilitation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/49e4c695-3a24-4966-abe7-90c73f94e5c5</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="AssembliesOfPervasiveServices.pdf">https://portal.research.lu.se/files/3171240/1287739.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4510241</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Computer Science, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Computer Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>LU-CS-DISS</title> </titleInfo> <identifier type="issn">1404-1219</identifier> <identifier type="isbn">978-91-976939-1-2</identifier> <identifier type="oldLupId">1287708</identifier> <part> <detail type="volume"> <number>2009-1</number> </detail> <extent unit="pages"> <total>205</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-02-19T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>49e4c695-3a24-4966-abe7-90c73f94e5c5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:07:29+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:07:29+02:00</recordDateApproved> </recordInfo> </mods>

Potential complications to OA treatment include damage to the exposed bowel resulting in enteric fistulas, and inability to close the abdomen afterwards resulting in large ventral hernias. Vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) is a novel technique for temporary closure of an OA, intended to increase the chances of subsequent delayed primary fascial closure without increasing the risk of complications. A classification system for the OA has been proposed by the World Society of the Abdominal Compartment Syndrome (WSACS), aimed at improving OA therapy and facilitating clinical research, but has not previously been evaluated.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Aims:&lt;br/&gt;&lt;br&gt; The aims were to study:&lt;br/&gt;&lt;br&gt; - Short-term clinical outcome of OA therapy with VAWCM with regards to fascial closure and factors associated&lt;br/&gt;&lt;br&gt; with failure of fascial closure, mortality, morbidity and possible technique-related complications.&lt;br/&gt;&lt;br&gt; - One-year clinical outcome of OA therapy with VAWCM with regards to the incidence of incisional- and parastomal hernias, abdominal wall discomfort and frequency of hernia repair operations after one year.&lt;br/&gt;&lt;br&gt; - Validity and reliability of the 2013 OA classification system by WSACS and to propose instructions for use with the classification.&lt;br/&gt;&lt;br&gt; - Physiological effects of vacuum therapy (VAWC) in an OA with regards to the extent of negative pressure reaching the bowel, the efficacy of the VAWC system in draining fluid from the abdominal cavity and whether paraffin gauzes can be effectively used as pressure isolation when placed between the vacuum source and the bowel.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Results/conclusions :&lt;br/&gt;&lt;br&gt; - VAWCM provided a high fascial closure rate after long-term OA treatment in mostly elderly, non-trauma patients. Technique-related complications were few and fistula incidence and mortality were similar to other studies.&lt;br/&gt;&lt;br&gt; - Incisional hernia incidence one year after OA therapy with VAWCM was high. Most hernias were small and asymptomatic and few required surgical repair during the first year.&lt;br/&gt;&lt;br&gt; - The validity and reliability analysis of the OA classification system by WSACS showed that each patient’s most complex OA grade, worsening OA grade without later improvement, as well as development of grade C (enteric leak) or grade 4 (entero-atmospheric fistula) were associated with worse outcome (mortality and failure of fascial closure). Every effort should be made to prevent patients from ascending to a more complex OA grade, to try to repair enteric leaks and to avoid enteroatmospheric fistulas.&lt;br/&gt;&lt;br&gt; - Negative pressure reaching the bowel during VAWC therapy was limited, regardless of negative pressure setting. Reduced therapy pressure did not lead to reduced pressure at the bowel surface. The system drained the abdominal cavity completely of fluid. Paraffin gauzes were of limited value as a means of isolation against pressure propagation.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; År 2005 opererades en 65-årig man i Malmö för ett bråck på stora kroppspulsådern. Det var en lång och komplicerad operation med stor blodförlust. Massiv blodöverföring och stora mängder vätska samt blodtryckshöjande mediciner måste tillföras under och efter operationen. Under det efterföljande dygnet steg trycket i bukhålan till en nivå då blodcirkulationen till njurarna och bukorganen påverkades med risk för bestående skador. I en sådan situation måste man åstadkomma en minskning av buktrycket och detta görs effektivast genom en ny operation där den ihop sydda bukväggen öppnas igen, vätska och blod avlägsnas ur bukhålan som sedan lämnas öppen, d.v.s. att bukväggen och såret inte sys ihop efter avslutad operation. På detta sätt åstadkommer man en maximal sänkning av trycket på organen. Detta gjordes i vår patients fall med syfte att, så snart svullnaden efter blödningen lagt sig, operera honom igen för att sy ihop bukväggen. Förutom blödning och svullnad kan det finnas andra orsaker som gör att man väljer att behandla med öppen buk (ÖB) under en viss tid. En kraftig infektion i bukhålan som behöver rensas upp eller blodcirkulationsstörning i tarmarna, som ofta kräver ytterligare operation inom något dygn, är andra exempel på orsaker till ÖB-behandling. Behandlingen kan vara livräddande men innebär också många svårigheter och risk för komplikationer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Under tiden buken är öppen måste de blottade tarmarna skyddas för att förhindra skador, som i värsta fall kan leda till att det går hål på tarmen och en s.k. tarmfistel, en fruktad och i dessa situationer inte sällan dödlig komplikation, uppstår. En annan svårighet är att det ofta rinner stora mängder vävnadsvätska från det öppna buksåret, som leder till vätskeförluster och behov av täta förbandsbyten, vilket är krävande för både patient och personal. Bukmusklerna drar isär sårkanterna och detta, tillsammans med bildning av sammanväxningar mellan bukväggens insida och tarmarna, gör att det i många fall inte är möjligt att sy ihop bukväggen igen trots att det akuta tillståndet är över. Resultatet blir då till slut ett stort invalidiserande bukväggsbråck, d.v.s. ett område med hudbeklädda tarmar utan täckande bukvägg, något som kräver en omfattande operation för att reparera i ett senare skede.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De senaste åren har behandling med ÖB blivit allt vanligare. Överlevnad hos svårt sjuka patienter har ökat men samtidigt har problemen som följer med behandlingen blivit synligare. Genom att bandagera såret med ett tarmskyddande lufttätt plastförband kopplat till en pump för skapande av ett reglerbart undertryck, minskar risken för tarmskador och chansen att kunna sy ihop buken igen ökar, samtidigt som sårvården förenklas. I tidigare mestadels nordamerikanska studier med denna metod, ingick till övervägande delen unga och för övrigt friska patienter som utsatts för skador och bara behövde en kortare tids behandling med ÖB. I Sverige är patienterna istället oftast äldre, med flera andra försvårande sjukdomar, som därmed ofta drabbas av ett komplicerat sjukdomsförlopp som kräver lång tids behandling. Vi upplevde tidigare att många av våra patienter inte gick att stänga buken på, trots användande av undertrycksbehandlingen som varit framgångsrik i de amerikanska rapporterna. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Just på detta sätt var det i vår patients fall. För att förbättra möjligheten till bukstängning arbetade vi fram en omläggningsteknik som kombinerar behandling med ett speciellt avpassat undertrycksförband med måttligt drag i bukväggskanterna genom ett insytt nät. Nätet är genomsläppligt för vätska som fortsatt kan dräneras genom förbandet, samtidigt som det motverkar att bukväggskanterna dras åt sidorna. När svullnaden i buken lagt sig kan kanterna successivt dras samman för att slutligen sys ihop, efter att nätet tagits bort. Vår patient ovan var den förste som detta prövades på, med stor framgång då bukväggen kunde sys ihop efter 14 dagars behandling. Det lyckade resultatet blev startskottet för de studier som ingår i denna avhandling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie I och II i avhandlingen gick ut på att bedöma behandlingsresultaten och möjliga komplikationer till metoden. På fyra sjukhus i Sverige behandlades 111 patienter med metoden under åren 2006 till 2009. Patienterna var gamla (median ålder 68 år) och svårt sjuka (nästan en tredjedel avled på sjukhuset) och behövde lång tids behandling med öppen buk (mediantid 2 veckor). Fem procent av patienterna utvecklade hål på tarmen, s.k. tarmfistel, vilket är jämförbart med andra studier. Komplikationer som direkt bedöms bero på tekniken var få. Bukväggen kunde sys ihop i en större andel av patienterna än vad som tidigare rapporterats. Av de som överlevde kunde bukväggen sys ihop hos 89 % och stängas med hjälp av förstärkande nät hos ytterligare 9 % Hos två patienter kunde bukväggen enbart delvis förslutas pga. brosk-bildning i såret och en av dessa patienter behövde opereras senare för ett bukväggsbråck. Efter ett år undersöktes patienterna på mottagningen samt med en datortomografi-undersökning (DT) av buken och bukväggen för bedömning av hur många bukväggs-bråck som uppkommit hos de 70 patienter som då fortfarande var i livet. Totalt kunde, i de flesta fallen små och symtomlösa bråck, påvisas hos 66 % av patienterna. Hade uppföljningen istället inskränkt sig till en fråga till patienterna om förekomst av en symptomgivande svullnad i snittet hade bråckfrekvensen fallit till 19 %. Resultaten visar: att tekniken är användbar även i situationer med äldre, svårt sjuka patienter; att risken för att skada tarmen är låg; att chansen är god att kunna sy ihop bukväggen; att det är vanligt med mindre men oftast symtomlösa bukväggsbråck efter ett år; och att det går att helt undvika de stora invalidiserande bukväggsbråcken vi tidigare hade sett. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I studie III utvärderades ett klassificeringssystem för ÖB, vars användande är av vikt för att kunna analysera och jämföra resultat av olika behandlingsmetoder. Klassificeringssystemet introducerades för några år sedan men har inte tidigare utvärderats vetenskapligt. Resultaten visade att systemets klassificeringsgrader, som avser att beskriva hur komplicerat tillståndet i den ÖB är, svarade väl mot behandlingsresultaten, den s.k. validiteten var hög. I vilken utsträckning olika användare gjorde liknande gradering enligt systemet samt hur samma användare graderade vid två olika tillfällen, den s.k. reliabiliteten för klassifikationssystemet testades också och befanns vara god. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie IV var en djurexperimentell studie där sex nedsövda grisar opererades och ÖB-förband anlades på samma sätt som vid behandling av våra patienter. Studiens syfte var att besvara tre frågor av vikt för säkerheten med användande av undertryck vid ÖB-behandling. En misstanke om att antalet tarmfistlar hade ökat med ökat användande av undertryck i samband med ÖB-behandling hade rapporterats i litteraturer. En förutsättning för att undertrycket skulle kunna vara förklaringen är att detta sprider sig genom förbandet till tarmen och där åstadkommer en sugorsakad skada. Den första delen av studien var att mäta undertrycket på olika lokaler i bukhålan under pågående undertrycksbehandling. Den andra delen av försöket gick ut på att mäta hur väl undertrycksförbandet avlägsnade vätska från bukhålan, en fråga som var viktig eftersom kvarvarande vätskerester kan bli infekterade och leda till varansamlingar och blodförgiftning. Den tredje frågan vi önskade besvara var om det fanns någon annan möjlighet att skydda tarmar och annan känslig vävnad från undertrycket än användande av det skyddande plastförband som vanligtvis läggs mellan tryckkällan och bukhålan. I vissa situationer, t.ex. om sammanväxningar mellan tarmar och bukväggens insida gjort att bukhålan inte längre är tillgänglig, så är det inte möjligt att applicera detta förband, men undertrycksbehandling kan ändå vara önskvärd att fortsätta. Det har föreslagits att vaselinindränkta kompresser, placerade mellan tryckkällan och den vävnad man önskar skydda, möjligen skulle kunna fungera genom att reducera undertrycket som verkar direkt på vävnaden. Resultaten av studiens olika delar visar: att undertrycket vid tarmytan var lågt och risken för sugskador på tarmen bedöms, som en följd av detta, vara liten; all vätska som finns i bukhålan sugs ut genom förbandet, vilket rimligen minskar risken för infektioner i bukhålan; att vaselinkompresser i flera lager inte förmår minska undertrycket från förbandet till underliggande vävnader, och den skyddande effekt av vaselinkompresser, som vi har noterat kliniskt, uppnås genom annan mekanism än minskat undertryck. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har vi i denna avhandling: undersökt behandlingsresultaten på kort och längre sikt av en ny behandlingsmetod för ÖB-behandling, som kombinerar undertrycksbehandling med nät-förmedlat drag i bukväggskanterna; utvärderat ett klassificeringssystem av vikt för framtida forskning om ÖB; samt klarlagt ett antal frågor rörande säkerheten vid användande av undertrycksbehandling vid ÖB.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Som nästa steg i vår forskning rörande ÖB-behandling väntar 5-årsuppföljning av våra studiepatienter, för utvärdering av bukväggsfunktion och livskvalitet. En förändring från användande av ett tillfälligt nät för drag i bukväggskanterna till förmån för ett permanent nät, som kan användas som förstärkning när buken sys ihop vid avslutningen av ÖB-behandlingen, är en spännande vidareutvecklingsmöjlighet. Detta skulle sannolikt undanröja problemen med de sena bukväggsbråcken men behöver studeras noga ur säkerhetssynpunkt.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0978464b-868e-465c-bd78-56e3372591d1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="OA_therapy_with_VAWCM.pdf">https://portal.research.lu.se/files/3174755/8261473.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3743460</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Open abdomen</topic> <topic>laparostomy</topic> <topic>VAWC</topic> <topic>NPWT</topic> <topic>TNP</topic> <topic>VAWCM</topic> <topic>classification</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-31-1</identifier> <identifier type="oldLupId">4221708</identifier> <part> <detail type="volume"> <number>2014:7</number> </detail> <extent unit="pages"> <total>177</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-01-17T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>0978464b-868e-465c-bd78-56e3372591d1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:07:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:07:38+02:00</recordDateApproved> </recordInfo> </mods>

The clinical applicability of the revised 2005 McDonald diagnostic criteria for PPMS was assessed in 17 patients. A file search identified two patients with tumefactive MS. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Results: The risk of developing MS after ON was 40% after a mean of 26 years. No patient developed MS 15 years or later after the ON. Risk factors for MS were abnormal CSF findings at baseline, winter onset, and recurrent ON. MRI at follow-up identified lesions compatible with MS in 20 out of 30 “healthy” patients with isolated ON. 15 out of 22 patients with ON demonstrated significant cognitive dysfunction, unrelated to MRI findings. 12 out of 17 patients with PPMS fulfilled the revised McDonald MRI criteria, whereas 5 patients required additional CSF analysis to establish a PPMS diagnosis. Both patients with tumefactive MS were diagnostic challenges, and developed severe brain oedema with mass effect which was successfully treated with decompressive hemicraniectomy.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Conclusions: Less than half of all our patients with an ON developed MS in the long term. Two thirds of patients who did not develop MS clinically had late MRI findings compatible with demyelinating disease; surprisingly no less than two thirds displayed cognitive impairment on detailed neuropsychological testing despite no apparent disabilities. In PPMS, MRI failed to establish the diagnosis in one third of the patients: CSF analysis should therefore be an integral part in the diagnostic work-up. Finally, clinical and neuroimaging features of tumefactive MS needs to be more widely recognized. High dose corticosteroids should be first line therapy, whereas decompressive craniectomy may be used in patients who develop mass effect with increased intracranial pressure (ICP).</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a7bf3284-e866-47cd-8740-c259d65f71db</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>optic neuritis</topic> <topic>multiple sclerosis</topic> <topic>cerebrospinal fluid</topic> <topic>magnetic resonance imaging</topic> <topic>prognosis</topic> <topic>cognition</topic> <topic>diagnosis</topic> <topic>primary progressive multiple sclerosis</topic> <topic>tumefactive MS</topic> <topic>craniectomy</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-01-9</identifier> <identifier type="oldLupId">1144947</identifier> <part> <detail type="volume"> <number>2008:48</number> </detail> <extent unit="pages"> <total>176</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-23T09:00:00+02:00</dateOther> <note type="additionalInfo">This work was supported by the Medical Faculty, University of Lund, Medical Research Council, The MS foundation of the University Hospital Lund, Research Found of the Department of Neurology Lund University Hospital, The Tage Bertoldy and Greta Hobro foundations, the Kock fundations, Alfred Österlund foundation and a scholarship from Biogen Idec.</note> <recordInfo> <recordIdentifier>a7bf3284-e866-47cd-8740-c259d65f71db</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:07:44+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:07:44+02:00</recordDateApproved> </recordInfo> </mods>

Both the&lt;br/&gt;&lt;br&gt; gains/losses profiles and the gene expression signatures revealed striking similarities&lt;br/&gt;&lt;br&gt; between the two tumour types. Leiomyosaromas and UPS were indistinguishable&lt;br/&gt;&lt;br&gt; using unsupervised hierarchical cluster analysis and significance analysis for&lt;br/&gt;&lt;br&gt; microarrays, which suggests a shared lineage.&lt;br/&gt;&lt;br&gt; In study II, whole-tumour sections from 239 STS were reviewed for size, vascular&lt;br/&gt;&lt;br&gt; invasion, necrosis, and peripheral growth pattern. All factors provided independent&lt;br/&gt;&lt;br&gt; prognostic information with hazard ratios (HRs) of 2.2-2.6 for development of&lt;br/&gt;&lt;br&gt; metastases in multivariate analysis. When combined into a prognostic model, referred&lt;br/&gt;&lt;br&gt; to as SING (Size, Invasion, Necrosis, Growth), high-risk tumours were identified&lt;br/&gt;&lt;br&gt; with a sensitivity of 74% and a specificity of 85%. SING compared favourably with&lt;br/&gt;&lt;br&gt; other currently used prognostic systems.&lt;br/&gt;&lt;br&gt; In study III, the prognostic value and clinical applicability of five proliferation&lt;br/&gt;&lt;br&gt; markers were assessed: Ki-67, Top2a, p21, p27Kip1 and S-phase fraction in a mixed&lt;br/&gt;&lt;br&gt; series of 196 STS of the extremities and the trunk wall, encompassing MFH/UPS,&lt;br/&gt;&lt;br&gt; leiomyosarcomas and liposarcomas. High S-phase fraction and high expression of Ki-&lt;br/&gt;&lt;br&gt; 67 and Top2a significantly correlated to risk for metastasis with HRs of 1.9-4.4.&lt;br/&gt;&lt;br&gt; Classification and regression tree analysis showed that Ki-67, Top2a and S-phase&lt;br/&gt;&lt;br&gt; identified different prognostic subgroups. This explorative analysis suggests that&lt;br/&gt;&lt;br&gt; proliferation markers could have a role in STS prognostication, in particular when&lt;br/&gt;&lt;br&gt; few other factors can be evaluated, as in the preoperative setting.&lt;br/&gt;&lt;br&gt; In study IV, ezrin expression was evaluated by immunohistochemistry on tissue&lt;br/&gt;&lt;br&gt; microarrays from a mixed series of 256 STS. Positive ezrin expression predicted&lt;br/&gt;&lt;br&gt; development of metastasis (HR=1.8) and local recurrence (HR=1.8) and was strongly&lt;br/&gt;&lt;br&gt; correlated to necrosis and growth pattern. Ezrin represents therefore a potential&lt;br/&gt;&lt;br&gt; marker for identification of high-risk sarcoma patients.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/82cd3520-15c1-479c-bac2-c0c84e5eac74</url> </location> </relatedItem> <originInfo> <publisher>Institute of Clinical Sciences, Department of Oncology, Skane University Hospital, Lund</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>MFH</topic> <topic>microarrays</topic> <topic>prognostic factors</topic> <topic>metastasis</topic> <topic>local recurrence</topic> <topic>proliferation</topic> <topic>Ki67</topic> <topic>Top2a</topic> <topic>p21</topic> <topic>p27</topic> <topic>S-phase fraction</topic> <topic>erzin.</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-05-5</identifier> <identifier type="oldLupId">1951742</identifier> <part> <detail type="volume"> <number>2011:56</number> </detail> <extent unit="pages"> <total>154</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-06-01T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>82cd3520-15c1-479c-bac2-c0c84e5eac74</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:07:59+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:07:59+02:00</recordDateApproved> </recordInfo> </mods>

The strange mixture of the high and the low, the sacred and the profane that is typical for them has been an interesting challenge for literary scholars. For instance, in older research one sometimes spoke of poor handwork, or bad taste of the writers or it was explained that these works were a stage between the end of romanticism and the beginning of realism. A common approach in the last years has been to leave such biographical and contextual discussions aside to investigate these semantic tensions as something typical of all forms of literary texts.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; However, the aim here has been to analyze some of the tension-filled passages in these works for their humor by using the cognitive humor theory of linguistics which describes the phenomenon as a bifurcated logical process – first the creation of discrepancy in the text being followed by the insight that the logical opposites may be related to each other when using the logic of the absurd.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This analysis combines the approaches of the cognitive humor theory with the terminology and analytic model of Michael Riffaterre developed in his Semiotics of Poetry (1978), where he shares the theoretical views of the linguists but focuses on literary texts. The results of this analysis are in a second stage related to a contemporary discussion of humor, above all the stand taken by the German writer Jean Paul in his Vorschule der Ästhetik (1804) and demonstrated in his novels Titan (1800-1803) and Des Luftschiffers Giannozzo Seebuch (1801).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The first step taken in the thesis shows that the tensions in the three chosen texts can be understood as deliberate, that is, as a form of humor, and that it can be said that these three texts share a common aesthetic. In opposition to the view often found in research that the texts are a transition from the romantic to realism the second comparative part of&lt;br/&gt;&lt;br&gt; the thesis shows that this humoristic aesthetic in many ways is close to the discussion of humor and of Witz to be found in Jean Pauls Vorschule der Ästhetik. A fruitful result of this analysis is the important place Christianity takes in this humoristic aesthetic. This partly opens new fields for research in the functions of allusions in these romantic&lt;br/&gt;&lt;br&gt; texts to the Old and New Testaments, but also in the role that emblems and the tradition of devotional literature play in these works.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6c40befe-6535-4bef-9f5b-eea54d237834</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="_20_20Jonas_20A_20HELA.pdf">https://portal.research.lu.se/files/3182033/1260066.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1143946</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Comparative Literature, Centre for Languages and Literature</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>C.F.

The thesis had a descriptive, cross-sectional and correlational design and&lt;br/&gt;&lt;br&gt; consisted of one paper where qualitative methodology was used and three where quantitative methodology was used. The qualitative study (I) was based on six focus group interviews with NAs (n=36) and the quantitative studies (II-IV) were based on questionnaires. A total of 225 NAs participated in studies II-III and a sub sample of these NAs (n=114) participated in study IV. All data was collected in the south of Sweden. A conventional content analysis was used for exploring the NAs’ experiences of job satisfaction (I), and descriptive and analytical statistics were used in order to investigate and explore associations of job satisfaction (II), strain/SC (III) and associated variables. In addition the psychometric properties in terms of the construct validity, data quality and reliability were investigated for the instruments used as dependent variables (IV). The results showed that the NAs’ job satisfaction and strain/SC constitute a complex web of interrelated aspects. Study I showed that the NAs’ job satisfaction was based on the encounter with the residents and their next of kin and the ability to establish significant relationships with them. They also experienced job satisfaction when they had the prerequisites to use and develop their competence and when they worked in a harmonious and inspiring environment. In studies II and III a positive caring climate was associated with high levels of job&lt;br/&gt;&lt;br&gt; satisfaction and inversely to low levels of strain/SC. In addition the extent of personalizing care, amount of organizational and environmental support and, leadership also contributed to positive as well as negative aspects of their wellbeing. Furthermore, health complaints showed to be related to negative affectivities of work. The psychometric properties of the instruments used in studies II-IV showed varying strengths and weaknesses (IV) and further development is thus needed. In conclusion, getting the prerequisites for providing high quality care, a positive caring climate, a high extent of personalizing care, a high amount of organizational and environmental support and last but not least having leaders and managers with good leadership characteristics appears to be important for the NAs’ wellbeing at work.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0369bf22-e770-4619-9eec-c71564448502</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Anneli_kappa_e_spik.pdf">https://portal.research.lu.se/files/3182104/4147104.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">836881</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Job satisfaction</topic> <topic>strain</topic> <topic>stress</topic> <topic>stress of conscience</topic> <topic>nurse assistants</topic> <topic>residential care</topic> <topic>long-term care</topic> <topic>quality of care</topic> <topic>leadership</topic> <topic>person-centred care</topic> <topic>caring climate</topic> <topic>health complaints</topic> <topic>psychometric properties</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-07-6</identifier> <identifier type="oldLupId">4147099</identifier> <part> <detail type="volume"> <number>2013:132</number> </detail> <extent unit="pages"> <total>171</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-12-07T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>0369bf22-e770-4619-9eec-c71564448502</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:08:20+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:08:20+02:00</recordDateApproved> </recordInfo> </mods>

Although only a minority of cases eventually progress to a life-threatening muscle-invasive tumour, it is necessary to conduct long-term follow-up with repeated cystoscopies. In addition to the negative mental and physical impact that this has on the patient, the examinations and the treatments of recurrence, impose an economic burden on the health care system. This thesis deals with various aspects of recurrent NMIBC. Paper I describes the present study of the genetic relationship between primary and recurrent tumours which revealed that in some cases there are fewer genetic aberrations in the latter than in the former. This finding contradicts the existance of a direct monoclonal relationsship between a primary and a recurrent tumour, although those lesions do show remarkably similar gene expression, which suggests that both are derived from a common progenitor cell. Paper II reports findings demonstrating that the voided urine marker, UroVysion® assay is too insensitive to replace cystoscopy in the follow-up of NMIBC patients. The results discussed in Paper III imply that only patients at low risk of recurrence benefit from early intravesical chemotherapy, and this disagrees with the European Association of Urology, which currently recommends that this treatment be given to all patients with presumed NMIBC. Paper IV demonstrates that biopsies from non-tumourous areas of bladder and prostatic urethra offer only about 50% sensitivity for carcinoma in situ (CIS). Lastly, as outlined in Paper V, none of the gene markers studied by the tissue microarray technique (i.e, TP53, CDH1, FGFR3, COX2, EGFR) were found to be associated with recurrence, but concerns were raised regarding the reliability of this methodology.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/87552e0e-a197-424f-87f2-bc2d2de9d860</url> </location> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>early instillation</topic> <topic>biopsies</topic> <topic>biomarkers</topic> <topic>recurrence</topic> <topic>bladder cancer</topic> <topic>non-muscle-invasive</topic> <topic>tissue microarray</topic> <topic>gene-expression</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-26-6</identifier> <identifier type="oldLupId">1712689</identifier> <identifier type="Scopus">77954946956</identifier> <part> <detail type="volume"> <number>2010:110</number> </detail> <extent unit="pages"> <total>146</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>https://www.scopus.com/pages/publications/77954946956</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-11-26T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>87552e0e-a197-424f-87f2-bc2d2de9d860</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:08:21+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:04:01Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:08:21+02:00</recordDateApproved> </recordInfo> </mods>

It shows how the National Socialist German Physicians’&lt;br/&gt;&lt;br&gt; Federation (NSDÄB) tried to strengthen connections with the Swedish medical&lt;br/&gt;&lt;br&gt; profession and academic medicine and to spread NS-propaganda to carefully selected&lt;br/&gt;&lt;br&gt; Swedish physicians. The dissertation consists of four papers.&lt;br/&gt;&lt;br&gt; In the first paper the international contacts and impact of the leader school&lt;br/&gt;&lt;br&gt; for German doctors (Führerschule der deutschen Ärzteschaft) in Alt Rehse 1935-&lt;br/&gt;&lt;br&gt; 1943 are examined through studies of a visitors’ book and of biographies. I suggest&lt;br/&gt;&lt;br&gt; that the Führerschule, an institution providing political and ideological education&lt;br/&gt;&lt;br&gt; for health professionals, interested international physicians to a larger&lt;br/&gt;&lt;br&gt; extent than earlier described. The legacy from the German elite school for physicians&lt;br/&gt;&lt;br&gt; in Alt Rehse also included some Swedish contacts and it was described in at&lt;br/&gt;&lt;br&gt; least one contemporary Swedish publication in 1938.&lt;br/&gt;&lt;br&gt; In the second and third papers I argue, that there existed, in the 1930’s and&lt;br/&gt;&lt;br&gt; 1940’s, well-functioning medical contacts between the two countries –&lt;br/&gt;&lt;br&gt; in spite&lt;br/&gt;&lt;br&gt; of the fact that the ’Swedish Society of Medicine’ tried to downplay the relations&lt;br/&gt;&lt;br&gt; with Germany.&lt;br/&gt;&lt;br&gt; Drawing on sources from private and state archives in Estonia, Germany&lt;br/&gt;&lt;br&gt; and Sweden, the fourth paper investigates the career of the gynaecologist Benno&lt;br/&gt;&lt;br&gt; Ottow (1884-1975): from his time as a junior physician period in Estonia and&lt;br/&gt;&lt;br&gt; Russia to his directorship of the Brandenburg gynaecological state hospital in&lt;br/&gt;&lt;br&gt; Berlin-Neukölln and the postwar-years spent in Sweden. During the Nazi dictatorship&lt;br/&gt;&lt;br&gt; Ottow demonstrated great commitment to putting the ideological and&lt;br/&gt;&lt;br&gt; legal demands into practice.&lt;br/&gt;&lt;br&gt; The general summary of the thesis is that the Swedish-German contacts in&lt;br/&gt;&lt;br&gt; medicine during the Third Reich years were multi-facetted and included both official&lt;br/&gt;&lt;br&gt; and unofficial contacts with prominent representatives of Swedish medicine&lt;br/&gt;&lt;br&gt; visiting Germany several times during the war years.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f8da4e7a-cef2-4d31-8cc6-7a243fa257c8</url> </location> </relatedItem> <originInfo> <publisher>Department of Medical Ethics, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Medicine</topic> <topic>History</topic> <topic>Physician</topic> <topic>Third Reich</topic> <topic>Germany</topic> <topic>Sweden</topic> </subject> <subject authority="lup"> <topic>History</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-08-6</identifier> <identifier type="oldLupId">3811184</identifier> <part> <detail type="volume"> <number>2013:38</number> </detail> <extent unit="pages"> <total>144</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-05-24T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f8da4e7a-cef2-4d31-8cc6-7a243fa257c8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:08:27+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:08:27+02:00</recordDateApproved> </recordInfo> </mods>

An area of increasing interest is the possible role of sexual activity and history of sexually transmitted infections as a risk factor for prostate cancer. Specific sexually transmitted infections have only inconsistently been associated with prostate cancer, with positive associations being reported with syphilis, gonorrhea and Human Papillomavirus (HPV) infection. Some studies have also reported detection of viral DNA in prostate cancer cells, although other studies have not reproduced these findings. Seroepidemiological studies offer an attractive alternative for investigation associations of infections with prostate cancer, as they allow i) a readily standardized measure of long-term viral exposure on a biological sample ii) are objective (i.e. independent of subjective reporting) and iii) allow study designs that are epidemiologically valid in terms of sufficient study size and adequate controls.&lt;br/&gt;&lt;br&gt; Aims: A large-scale epidemiological evaluation of possible associations between prostate cancer and infection with HPV-6, HPV-11, HPV-16, HPV-18 and HPV-52, Herpes simplex virus 2 (HSV-2) and Human Herpesvirus 8 (HHV-8) as well as two common human polyomaviruses (BK and JC).&lt;br/&gt;&lt;br&gt; Results: Paper I is based on a follow-up of up to 24 years of the serum biobank of the Finnish Social Insurance agency, that identified 165 cases of prospectively occurring prostate cancer cases and matched controls that did not develop cancer during a similar length of follow-up. The seroprevalence of STIs was low in this cohort (2,4% for HHV-8 and 6,9% for HSV-2) and were not associated with prostate cancer risk (OR for prostate cancer if HHV-8-positive 0.74 (95% CI, 0.19–2.88), if HSV-2-positive 0.93 (95% CI, 0.44–1.96). &lt;br/&gt;&lt;br&gt; In paper II, we used the biobanks that collaborate in the Nordic Biological Specimen Biobank Working Group on Cancer, Causes and Control that have jointly enrolled more than 200,000 men. Registry linkages identified 799 prospectively occurring cases of cancer and a selection of 2596 matched controls that did not develop prostate cancer. Seroprevalences for HPV-16, -18 or -33 were not significantly associated with prostate cancer risk, neither in the joint cohort nor in any one of the collaborating biobanks in the network. In paper III, we developed a multiplexed serology system for simultaneous one-tube detection of antibodies to several STIs (sexually transmitted infections) and applied it to a population-based case-control study of 245 men with prostate cancer and 204 matched controls. Seropositivities against HPV-6, -16, -18 and &lt;br/&gt;&lt;br&gt; -52, HSV-2 or HHV-8 were not associated with prostate cancer. On the contrary, presence of multiple STIs was actually less common among prostate cancer patients (OR 0.18: 95% CI 0.04-0.83). In paper IV, we applied our multiplexed serology system to an even larger population-based case-control study of 2953 men with prostate cancer and 1819 population-based controls. The only infection that was significantly associated with prostate cancer was HHV-8, an inverse association (OR: 0,67; 95% Confidence Interval (CI): 0,51- 0,87). Conclusion: Technical development in high-throughput serology (“serolomics”) enabled sufficiently large-scale epidemiological studies to evaluate the STI hypothesis in prostate carcinogenesis. However, our studies which where of large size and had fairly strong statistical power, showed that it is unlikely, that there would exist any positive associations of STIs and prostate cancer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7a0fa6a9-cabf-4064-9507-2c5b8aa4f44a</url> </location> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-03-3</identifier> <identifier type="oldLupId">1149895</identifier> <part> <detail type="volume"> <number>2008:50</number> </detail> <extent unit="pages"> <total>132</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-06-16T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>7a0fa6a9-cabf-4064-9507-2c5b8aa4f44a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:08:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:08:38+02:00</recordDateApproved> </recordInfo> </mods>

The lung is recognized as the most sensitive and critical organ affected by the hyper-inflammatory response in septic patients. Immune cell dysfunction develops in later phases of sepsis making patients susceptible to infections. The aim of this dissertation was to reveal pro- and anti-inflammatory mechanisms in abdominal sepsis induced by cecal ligation and puncture (CLP). It was found that immunoneutralization of LFA-1 or Mac-1 not only reduced neutrophil infiltration but also protected against sepsis-caused lung damage. We observed that HMG-CoA reductase inhibitor regulates pulmonary accumulation of neutrophils via antagonizing CD40 ligand secretion from platelets and via decreasing CXC chemokine formation in the lung. Moreover, HMG-CoA reductase inhibition maintained CD4 T-cell function in spleen by reducing apoptosis and by improving proliferation as well as by preserving the ability to produce IFN-γ in the spleen. Moreover, inhibition of HMG-CoA reductase decreased sepsis-induced generation of regulatory T-cells. HMG-CoA reductase inhibitor abolished CLP-evoked increase in the plasma levels of HMGB1 and IL-6. In addition, it was noted that NFAT was activated after induction of sepsis, which was found to regulate pulmonary neutrophil recruitment and tissue damage, systemic inflammation, as well as T-cell dysfunction in abdominal sepsis. Thus, these results identify adhesive and signaling mechanisms, which are of particular importance in modulating septic lung injury and immunosuppression. Data from this thesis may pave the way for developing more specific and effective therapies for patients with abdominal sepsis.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/89085fc1-d7e4-407c-9eb0-7c6fd9ccce3d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Su_Zhang_HELA.pdf">https://portal.research.lu.se/files/3187970/2517763.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">10538811</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Section for Surgery, Clinical Sciences, Malmö</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>abdominal sepsis</topic> <topic>lung</topic> <topic>infection</topic> <topic>neutrophil</topic> <topic>chemokines</topic> <topic>T-cells</topic> <topic>HMG-CoA reductase</topic> <topic>NFAT</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-06-7</identifier> <identifier type="oldLupId">2517719</identifier> <part> <detail type="volume"> <number>2012:44</number> </detail> <extent unit="pages"> <total>138</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-05-24T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>89085fc1-d7e4-407c-9eb0-7c6fd9ccce3d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:08:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:08:58+02:00</recordDateApproved> </recordInfo> </mods>

The aim of present thesis was to investigate the impact of long-term hyperglycemia on the pancreatic islet β-cell function.&lt;br/&gt;&lt;br&gt; The data showed abnormally increased expression of inducible nitric oxide synthase (iNOS) protein in the islets from diabetic donors as well as in the islets exposed to chronic hyperglycemia. cAMP analogue or PDE inhibitors counteract these abnormalities and restore β-cell function at least in part, by activating cyclic AMP/PKA system. Using two different diabetic animal models i.e. mild hyperlipidemic ZDF (fa/fa) and hyperglycemic GK rat, we found that chronic hyperglycemia in the absence of hyperlipidemia almost abolish GPR40 expression in the islet cells and abrogate the FFA-induced secretory effects. We suggest that this might be an important contributing factor for dysfunction of β-cells seen in human type 2 diabetes (T2D).&lt;br/&gt;&lt;br&gt; Furthermore we also observed that prolonged exposure of INS-1E and INS-1 832/13 cells or isolated human islets to high glucose concentration are associated with increased level of VDAC1 and reduced level of VDAC2 accompanied with marked reduction of GSIS. Similar to glucose, 2-deoxy-glucose also increased the expression of VDAC1. Addition of glycogen synthase kinase 3β (GSK-3β) inhibitor reversed the alteration in VDAC1/VADC2 expression and improved GSIS. Islets of type 2 diabetic donors showed increased expression of VDAC1 and a marked reduction of VDAC2. Diabetic islets also displayed increased expression of ChREBP and TXNIP. Down-regulation of ChREBP and TXNIP in INS-1 832/13 cells cultured at high glucose suppressed high glucose-induced increase in VDAC1 expression. The cultured INS-1 832/13 cells also exhibited a reduced expression of VADC1 when resveratrol (a polyphenolic compound) was present.&lt;br/&gt;&lt;br&gt; The data suggest that an increased expression of iNOS, increased expression of VDAC1 and reduced expression of VDAC2 are the main causative factors in the pathogenesis of glucotoxicity. The GPR40 protein is interactively modulated by both hyperlipidemia and hyperglycemia. Taken together, these contributing signaling factors are promising targets for pharmacotherapy in different variants of type 2 diabetes.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Typ 2-diabetes mellitus ökar över hela världen med en trend av minskande debutålder. Sjukdomen är ett komplext natur som kan ses som en rad olika metabola sjukdomar med delvis lika symtom, men med helt olika bakgrundsorsaker. Gemensamt för alla varianter av diabetes är att blodsockret är förhöjt även vid fasta. Typ 2-diabetes kännetecknas av insulinresistens och en progressiv förlust av insulinfrisättning från de pankreatiska β-cellerna. Förmågan att utsöndra tillräckliga mängder insulin bestäms av den funktionella kapaciteten hos pankreatiska β-celler och deras totala massa. &lt;br/&gt;&lt;br&gt; Glukos, eller druvsocker, är den huvudsakliga regulatorn av insulinproduktion och dess utsöndring i blodet.Om glukoskoncentrationerna är förhöjda över en längre period, har detta negativa effekter på β-cellfunktion, som sammanfattas med begreppet &quot;glucotoxicitet&quot;. Denna leder till metaboliska avvikelser i β-cellen som endast är delvis kartlagda, men klart är att glukotoxicitet förknippas med ökad basal insulinfrisättning, minskad respons på stimuli att utsöndra insulin, och en gradvis utarmning av insulinproduktion. Glukotoxicitet leder också till minskad β-cellmassa genom induktion av apoptos, om denna inte kompenseras av en kompensatorisk ökning av β-cellproliferation och neogenes (nybildning). &lt;br/&gt;&lt;br&gt; Hos alla typ 2-diabetiker ser man, trots aggressiv läkemedelsbehandling, med tiden en obeveklig nedgång i den insulinproducerande β-cellens funktion. Nedgången beror åtminstone delvis på induktion av vissa enzymer som ökar produktionen av en rad reaktiva molekyler som kväveoxid (NO) och reaktiva syreradikaler (ROS), vilka är etablerade stressfaktorer och påverkar β-cellerna negativt.&lt;br/&gt;&lt;br&gt; Mitokondrierna är centrala i energiomsättningen genom att tillverka energirika föreningar såsom ATP och GTP, och helt oundgängliga för optimal β-cellsfunktion. Hur glucotoxicitet påverkar mitokondriefunktionen är inte känt i detalj.&lt;br/&gt;&lt;br&gt; Med hjälp av olika tekniker såsom immunohistokemi, Western blot, kvantitativ PCR, masspektrometri, cellviabilitet- och hormon-analys, har jag undersökt de mekanismer som kan vara av intresse och presenterat våra senaste fynd angående de strukturella och funktionella förändringar som glucotoxicitet leder till i β-celler. Obehandlade kan dessa förändringar leda till β-cellsdysfunktion som kommer att kulminera i diabetes mellitus typ 2.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Beskrivning av delarbete 1-4 &lt;br/&gt;&lt;br&gt; I den första studien upptäckte jag ett onormalt ökat uttryck av det inducerbara enzymet kväveoxidsyntas (iNOS) i pankreatiska öar från typ 2 diabetiska donatorer samt från öar som utsattes för kronisk hyperglykemi (in vitro). Induktionen av iNOS leder till produktion av mycket höga nivåer av NO som är toxiskt för β-cellen. Vi föreslår att detta kan vara en bidragande faktor för β-cell dysfunktion som ses vid typ 2-diabetes (T2D). Jag visade också att en ökning av den intracellulära signalmolekylen cAMP kunde motverka induktionen av iNOS och åtminstone delvis återställa β-cellsfunktionen genom aktivering av cykliskt AMP/PKA-systemet. &lt;br/&gt;&lt;br&gt; I den andra studien fann vi att GPR40, en membranbunden receptor som binder vissa fettsyror, är rikligt uttryckt i de Langerhanska ö-cellerna hos råtta och att GPR40 är av stor vikt vid reglering av insulin-, glukagon- och somatostatinutsöndring medierad av fettsyran palmitat. En mild hyperlipidemi ökar GPR40 uttrycket i de pankreatiska ö-cellerna hos råtta. Hyperglykemi har motsatt effekt och nedreglerar uttryck av GPR40 och motverkar palmitat-inducerad hormonsekretion. Vidare fann vi också att GPR40 är lågt uttryckt i pankreatiska ö-celler från den diabetiska råttstammen GK. Vi tror att GPR40 protein uttrycket påverkas olika av både FFA och glukos och är en lovande måltavla för läkemedelsbehandling (GPR40-antagonister och agonister) inom olika varianter av typ 2-diabetes.&lt;br/&gt;&lt;br&gt; I de tredje och fjärde delstudierna fann vi att kronisk glukosexponering av insulinproducerande β-celler (INS-1E och INS-1 832/13 celler) eller isolerade humana pankreatiska öar är förknippad med ökad nivå av det mitokondriella kanalproteinet VDAC1, medan den liknande molekylen VDAC2 har minskat uttryck. Samtidigt observerades en tydlig minskning av glukosstimulerad insulin-frisättning (GSIS). I likhet med dessa experiment, visade pankreatiska öar tagna från typ 2-diabetiska donatorer ett ökat uttryck av VDAC1 och ett minskat uttryck av VDAC2. Jag fann också att uttrycket av VDAC1 kunde vara direkt eller indirekt under kontroll av transkriptionsfaktorerna ChREBP och TXNIP. Denna idé stöddes av observationen att nedreglering av ChREBP eller TXNIP i INS-1 832/13 celler odlade vid hög glukoshalt ledde till en kraftigt minskad glukosinducerad ökning av VDAC1. Uttryck av VDAC1 kan också nedregleras farmakologiskt av substansen resveratrol som utvinns ur grapefruktskal, vilket motverkade effekten av högt glukos. &lt;br/&gt;&lt;br&gt; Sammanfattningsvis föreslår vi att ett förändrat uttryck av VDAC1 och VDAC2, eventuellt via ökade intracellulära stresssignaler, är en nyckelkomponent i patogenesen av glucotoxicitet vilket leder till strukturella och funktionella förändringar i pankreatiska insulin-producerande celler som resulterar i försämrad insulinutsöndring.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c7d730aa-80a3-4750-b3c3-be37825beac1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis_2012-09-14..pdf">https://portal.research.lu.se/files/3188582/3158212.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1661939</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Diabetes Centre, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cAMP/PKA system</topic> <topic>iNOS</topic> <topic>Type 2 diabetes</topic> <topic>GSIS</topic> <topic>PDE</topic> <topic>GK rat</topic> <topic>ZDF (fa/fa)rat</topic> <topic>GPR40</topic> <topic>VDAC1</topic> <topic>VDAC2</topic> <topic>GSK-3β</topic> <topic>ChREBP</topic> <topic>TXNIP</topic> <topic>resveratrol.</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-45-6</identifier> <identifier type="oldLupId">3158162</identifier> <part> <detail type="volume"> <number>2012:82</number> </detail> <extent unit="pages"> <total>174</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-10-19T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>c7d730aa-80a3-4750-b3c3-be37825beac1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:09:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:09:11+02:00</recordDateApproved> </recordInfo> </mods>

T1D is characterized by a primary defect in insulin secretion due to the immune-mediated beta cell destruction, however, the more common T2D beside insulin resistance also include impaired beta cell function as a consequence to abnormal glucose homeostasis. Genetic susceptibility is involved in both types of diabetes. We have studied several genetic and immunological factors affecting beta cell function. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; First, we tested whether single nucleotide polymorphisms (SNPs) of the human Free Fatty Acid Receptor 1 (FFAR1) are associated with T2D and insulin secretion. Another genetic study focused on FOXP3 association with T1D and the disease-related clinical parameters. The role of microRNAs (miRNAs) on beta cell function was studied in the third project using a novel genetically engineered mouse model. Subsequently, the effect of Alpha 1-Antitrypsin (AAT) on cytokine-induced apoptosis and on insulin secretion was studied in beta cells in vitro. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In Study I, we concluded that SNPs rs1978013 and rs1978014 in the upstream region of FFAR1 gene might contribute to impaired beta cell function in T2D. Study II showed that the minor A allele in the FOXP3 rs2232365 SNP might represent a protective factor in T1D pathogenesis and suggest a possible role of FOXP3 in the regulation of autoimmunity against pancreatic beta cells. We have demonstrated for the first time in Study III that targeted disruption of the Dicer1 gene specifically in beta cells leads to progressive impairment of insulin secretion and diabetes development. Our findings of Study IV show that AAT stimulates insulin secretion and protects beta cells against cytokine-induced apoptosis, and these effects of AAT seems to be mediated through the cAMP pathway.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ef479246-001e-4db0-bb31-b145ccaa5214</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>animal model</topic> <topic>Dicer1</topic> <topic>genetics</topic> <topic>genetic association</topic> <topic>single nucleotide polymorphism</topic> <topic>SNP</topic> <topic>INS-1E</topic> <topic>AAT</topic> <topic>FOXP3</topic> <topic>beta cell function</topic> <topic>insulin secretion</topic> <topic>FFAR1</topic> <topic>insulin</topic> <topic>T2D</topic> <topic>glucose</topic> <topic>T1D</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-49-3</identifier> <identifier type="oldLupId">1390721</identifier> <part> <detail type="volume"> <number>2009:61</number> </detail> <extent unit="pages"> <total>162</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-16T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>ef479246-001e-4db0-bb31-b145ccaa5214</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:09:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-27T13:11:59Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:09:16+02:00</recordDateApproved> </recordInfo> </mods>

It is today widely acknowledged that hypoxia and hypoxia-inducible factors (HIF:s) contribute to tumor progression. We therefore set out to explore the impact of hypoxia on mammary epithelial differentiation and what consequences the hypoxic response might have on breast cancer development and behavior. We found that hypoxia induces&lt;br/&gt;&lt;br&gt; a less differentiated, estrogen receptor (ER)-negative/cytokeratin (CK) 19-positive phenotype in mammary cancer cells in vivo and in vitro and suggest that hypoxiainduced dedifferentiation is one of the mechanisms behind hypoxia-driven malignant progression. Hypoxia was also found to significantly impair both morphological and functional differentiation of non-transformed, immortalized epithelial mammary cells grown in three-dimensional cultures. Heterogeneous ER expression in breast cancer was&lt;br/&gt;&lt;br&gt; additionally found to be related to cyclin D1, a cell cycle regulator frequently overexpressed in breast cancer. As cyclin D1 expression was not affected by hypoxia, our findings suggest two separate mechanisms behind varied ER expression in breast cancer. The two pivotal regulators of hypoxic response, HIF-1α and HIF-2α, were analyzed in two cohorts of breast cancer patients and found to be un-correlated suggesting HIF-α&lt;br/&gt;&lt;br&gt; subtype specific mechanisms of induction. Furthermore, HIF-2α was found to be an independent prognostic factor related to distant recurrence.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d74d8c94-d194-43c5-806c-1200ae730aff</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Karolina_H._utan_PEK.pdf">https://portal.research.lu.se/files/3195246/1149413.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">621931</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Differentiation</topic> <topic>Hypoxia</topic> <topic>Breast cancer</topic> <topic>Breast</topic> <topic>HiF-1</topic> <topic>HiF-2</topic> <topic>3D-cultures</topic> <topic>prognosis</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-14-9</identifier> <identifier type="oldLupId">1149298</identifier> <part> <detail type="volume"> <number>2008:61</number> </detail> <extent unit="pages"> <total>111</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-29T09:15:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

An educated guess is that the number of executing PID control loops lies in the billions (2011) and there are no signs indicating a decrease of this number. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Properly tuning the PID controller, i.e., setting its parameter values based on characteristics of the process it controls together with robustness criteria, is commonly both timely and costly. Hence, the tuning is often overseen, resulting in numerous poorly tuned loops. These result in unnecessary lack of performance, which might be both hazardous and uneconomic.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; If a linear time invariant model of the process is given, there exists numerous feasible tuning methods. However, automatically obtaining even a low complexity model is far from trivial in the absence of a priori process information.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis addresses system identification to be used in the automatic PID tuning procedure. A method for generating the identification input signal is proposed. Its objective is to yield higher model accuracy in the frequency range where it is most needed for robust tuning. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Subsequently, methods for obtaining process models from input and output data pairs are proposed and discussed. All methods are presented using numerous simulations and laboratory experiments.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Finally, a simulation study of closed-loop anesthesia in human patients, based on clinically obtained model parameters, is presented. The novelty lies in that the depth of hypnosis PID controller is individualized based on data collected during the induction phase of anesthesia. It is demonstrated that updating the controller, using a herein proposed method, significantly improves performance.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/847ca38e-93e8-4188-b3d5-8ec6c23f2132</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="soltesz12b.pdf">https://portal.research.lu.se/files/20277457/8168791.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4688936</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Research Reports TFRT-3254</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">2293573</identifier> <part> <extent unit="pages"> <total>86</total> </extent> </part> </relatedItem> <recordInfo> <recordIdentifier>847ca38e-93e8-4188-b3d5-8ec6c23f2132</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:09:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-23T11:44:08Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:09:24+02:00</recordDateApproved> </recordInfo> </mods>

The size of myocardial injury is one more important factor influencing the&lt;br/&gt;&lt;br&gt; prognosis of STEMI patients. The search for new non-invasive markers, which can be relatively simply calculated using&lt;br/&gt;&lt;br&gt; conventional ECG recording and can predict the degree of myocardial injury and impending VF, is promising. This work is&lt;br/&gt;&lt;br&gt; aimed at investigating cardiac repolarization and depolarization abnormalities and predictors and prognosis of ventricular&lt;br/&gt;&lt;br&gt; arrhythmias during the course of STEMI.&lt;br/&gt;&lt;br&gt; The thesis is composed of the experimental part (Studies I, II, III) and clinical register-based retrospective studies (Studies IV&lt;br/&gt;&lt;br&gt; and V). Closed-chest porcine model of myocardial infarction (MI) was used in the experimental part. Occlusion of left&lt;br/&gt;&lt;br&gt; descending artery (LAD) lasted 40 minutes and was followed by reperfusion, and ECG was continuously recorded. QRSduration&lt;br/&gt;&lt;br&gt; and morphology, dynamics of ST-segment and T-wave alternans (TWA) were calculated, and myocardial area at&lt;br/&gt;&lt;br&gt; risk (MaR) and infarct size (IS) were assessed. Predictors and prognostic impact of early VF in STEMI was assessed in a&lt;br/&gt;&lt;br&gt; register-based study of 1,718 consecutive patients admitted for primary PCI during 2007-2009 who were followed up for&lt;br/&gt;&lt;br&gt; one year.&lt;br/&gt;&lt;br&gt; In experimental MI, the maximal level of TWA during occlusion period was associated with both MaR and IS (Study II).&lt;br/&gt;&lt;br&gt; Rapid and marked transient increase in QRS duration associated with appearance of J-wave pattern predicted impending VF&lt;br/&gt;&lt;br&gt; in acute ischemia (Study III). Restoration of blood flow in infarct-related artery was accompanied by reperfusion peak in all&lt;br/&gt;&lt;br&gt; animals, and the magnitude of ST elevation at reperfusion peak was associated with infarct size (Study I). In clinical studies&lt;br/&gt;&lt;br&gt; IV and V, the risk of VF in acute period of STEMI was higher in patients with MI history, cardiovascular risk factors such as&lt;br/&gt;&lt;br&gt; smoking and left main stenosis, resulting in a large infarct area. Besides MI history and left main stenosis, the risk of VF at&lt;br/&gt;&lt;br&gt; reperfusion was associated with inferior localization of STEMI, hypokalemia, high ST-elevation and shorter symptom-toballoon&lt;br/&gt;&lt;br&gt; time. The magnitude of ST-elevation before PCI for STEMI independently predicted reperfusion VF. Patients&lt;br/&gt;&lt;br&gt; successfully resuscitated after VF and alive at 48 hours had higher in-hospital mortality (12% vs. 2%, p&amp;lt;0.001). However, in&lt;br/&gt;&lt;br&gt; VF patients who were discharged alive, 1-year mortality did not differ compared with patients without VF</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6639817c-b0b9-41d7-b65a-1138d311ccf4</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="PhD_thesis_book_with_papers.pdf">https://portal.research.lu.se/files/3195505/8034421.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9691243</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Cardiology, Clinical Science, Lund, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-167-5</identifier> <identifier type="oldLupId">8034420</identifier> <part> <detail type="volume"> <number>2015:88</number> </detail> <extent unit="pages"> <total>79</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-09-18T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>6639817c-b0b9-41d7-b65a-1138d311ccf4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:09:25+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:09:25+02:00</recordDateApproved> </recordInfo> </mods>

HSCs may self-renew (the process whereby HSCs replicate to produce new HSCs) to preserve their own numbers, as well as initiate a highly coordinated hierarchical differentiation process that results in the production of mature effector blood cells. Aging is characterized by an overall loss of cellular and organ fitness, which has been suggested to result from alterations in tissue-resident somatic stem cell function. In the blood, aging presents with several functional alterations that can be traced to cell intrinsic alterations occurring in HSCs. HSC aging has been suggested to result from accumulation of DNA damage in genomic and/or mitochondrial DNA (mtDNA). We addressed the latter in article I using mice that rapidly accumulate mtDNA mutations and display several premature aging phenotypes. These “mutator mice” displayed several hematopoietic abnormalities associated with aging, including anemia and defects in lymphopoiesis. However, several hallmarks associated with HSC aging was lacking. In addition, the observed phenotypes appeared to result from alterations in progenitor cells rather than in HSCs. Thus, we concluded that mtDNA mutations are unlikely to be the main drivers of hematopoietic aging. In article II, we investigated the relevance of epigenetic alterations for hematopoietic aging. To this end, we generated induced pluripotent stem (iPS) cells from aged hematopoietic stem and progenitor cells (HSPCs), since cellular reprogramming coincides with an epigenetic reset of the somatic donor cells. We next redifferentiated the resulting iPS cells into blood in vivo and investigated the resulting hematopoiesis for age-related parameters. This revealed that the reformed blood system displayed a balanced lineage potential, with HSC numbers and function comparable to the young setting. Therefore, we concluded that a major component of hematopoietic aging involves reversible epigenetic alterations. While mtDNA mutations appeared to impact little on somatic stem cell function per se (article I), little is known about their impact on iPS cells function. To address this, we generated iPS cells from mutator HSPCs. Although mutator iPS cells were readily formed, these displayed severe differentiation defects (article III). We traced this to a failure of mutator iPS cells to utilize mitochondrial driven oxidative phosphorylation during differentiation. In article IV, we set out to identify individual novel regulators that may impact on early hematopoietic cell fate decisions. This led to the identification of the transcription factor Hepatic Leukemia Factor (Hlf). Enforced Hlf expression could direct early cell fate decisions of multipotent GMLPs by strongly favoring myelopoiesis over lymphopoiesis. This indicates that Hlf is a key determinant of lineage fate and an important component in the regulatory networks of multipotency.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Varje dag produceras miljardtals nya blodceller, vilka exempelvis har som uppgift att transportera runt syre och försvara kroppen mot olika invaderande bakterier och virus. Dessa olika blodkomponenter har sitt ursprung i sällsynta blodbildande stamceller som återfinns i benmärgen. Dessa är så kallade vävnadsspecifika stamceller och har både förmågan att återbilda sig själva (självförnyelse) och att initiera en differentieringskaskad som till slut leder till bildandet av de mogna immunförsvarscellerna. Det sistnämnda involverar många intermediära celltyper (progenitorceller) som succesivt förlorar sin differentieringspotential innan en given progenitorcell ”låses” mot att endast ge upphov till en mogen blodcellstyp. Denna process är därför strikt ordnad i ett hierarkiskt system och möjliggör livslång tillförsel av mogna blodceller. Trots detta kan dessvärre olika sjukdomar med sitt ursprung i blodet uppkomma och en del av dessa är dessutom tydligt associerade med att man blir äldre. Studier i möss har visat att detta kan relateras till förändringar i de blodbildande stamcellerna. Exempelvis blir celler av den medfödda delen av immunförsvaret vanligare på bekostnad av celler av det adaptiva immunförsvaret. Det förstnämnda har som funktion att förmedla snabba, förhållandevis ospecifika svar medan det adaptiva immunförsvaret ger mer specifika svar på invaderande patogener. Denna åldersrelaterade förändring kan bland mycket annat relateras till att blodsjukdomar hos äldre individer oftare har sitt ursprung i just det medfödda immunförsvaret.&lt;br/&gt;&lt;br&gt; Mycket forskning har riktats mot att förstå hur sjukdomsförlopp och normal blodcellsbildning i yngre och äldre personer går till, men trots detta saknas fortfarande många viktiga pusselbitar för att nå en helhetsförståelse av dessa processer. I denna avhandling har jag därför fokuserat på att dra mitt strå till stacken och försökt identifiera olika molekylära mekanismer som är inblandade i dessa processer.&lt;br/&gt;&lt;br&gt; Åldersprocessen har föreslagits bero på skador och mutationer i cellernas DNA som återfinns både i cellkärnan och i cellernas mitokondrier. De sistnämnda är viktiga cellkomponenter, som bland annat har den livsnödvändiga uppgiften att producera energi, och skador i mitokondriernas DNA skulle därför kunna påverka dessa funktioner. I artikel I undersökte vi därför om åldrandet av blodet är kopplat till uppkomsten av mitokondriemutationer och använde oss av en musmodell som succesivt leder till en ökning av mitokondriemutationer, vilket resulterar i flera symptom som förknippas med åldrande. Dessa studier ledde till insikten att en intakt mitokondriefunktion är viktig för en adekvat blodcellsbildning, men att en nedsatt sådan inte på egen hand kan förklara de åldersrelaterade förändringar som uppkommer i blodet.&lt;br/&gt;&lt;br&gt; Utöver permanenta skador i cellernas DNA har åldrande också föreslagits bero på förändringar i cellers genuttrycksmönster och i de faktorer som reglerar detta. I artikel II adresserade vi huruvida sådana förändringar är stabilt förekommande i blodet och om detta skulle kunna förklara åldersprocessen. Vi fann att sådana genuttrycksförändringar sker i åldrande blodstamceller och intressant nog fann vi att dessa är direkt involverade i de funktionella förändringarna som är associerade med åldrandet i blodet. Detta eftersom en återställning av dessa ledde till att blodsystemet från en gammal mus uppträdde som det hos en ung mus. Därför drog vi slutsatsen att åldrande i blodet uppkommer som följd av förändringar i de åldrande blodcellernas genuttrycksmönster och de faktorer som reglerar dessa.&lt;br/&gt;&lt;br&gt; För att adressera frågeställningarna i artikel II använde vi oss av så kallad ”cellreprogrammering”, vilket omvandlar en given kroppslig cell till en pluripotent stamcell; en typ av cell som kan ses som ett slags embryonalt förstadium med förmågan att återbilda alla olika celler i kroppen. Eftersom detta ledde till en återställning av de åldersrelaterade förändringarna i blodet var vi i artikel III intresserade av att utvärdera om denna process även skulle kunna mildra ålderssymptom som uppkommer som en följd av mitokondriemutationer. För att svara på detta omvandlade vi blodceller med mitokondriemutationer till samma typ av pluripotenta stamceller. I dessa studier fann vi att mitokondriemutationer i de resulterande pluripotenta stamcellerna ledde till en oförmåga i dessa cellers möjlighet att bilda kroppens olika mogna celltyper. Vi drog således slutsatsen att mitokondriemutationer kan ha starka negativa effekter på pluripotenta stamcellers funktion och att förekomsten av dessa inte kan ”rejuveneras” med hjälp av cellreprogrammering.&lt;br/&gt;&lt;br&gt; I artikel IV var vi intresserade av att nå en ökad förståelse för enskilda faktorer som är inblandade i att styra blodcellsbildningen mot olika typer av mogna celltyper. Dessa mekanismer är viktiga att nå detaljerad förståelse kring eftersom de förändras vid olika blodsjukdomar men också, som nämnts ovan, vid åldrande. På basis av detta identifierade vi genen Hlf som visade sig kunna styra utvecklingen av omogna progenitorceller mot att nästan exklusivt bilda celler av det medfödda immunförsvaret på bekostnad av adaptiva immunförsvarsceller. Vi drog därför slutsatsen att Hlf är en viktig komponent i det komplexa nätverk som styr nybildningen av mogna celler i immunförsvaret.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ec842b22-3968-411b-b705-9734e48d52cc</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis.pdf">https://portal.research.lu.se/files/3195581/4330132.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2013146</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Stem Cell Aging</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-52-6</identifier> <identifier type="oldLupId">4319341</identifier> <part> <detail type="volume"> <number>2014:28</number> </detail> <extent unit="pages"> <total>164</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-03-14T13:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The relationship between legal rules and social norms play a crucial part in the analysis. The study takes place within the framework of the broader question of how traffic control and sanctioning systems in general influence the road-users behaviour. Other strategies such as education, information or various technical solutions are ever so important but fall outside the scope of the specific issue being investigated in this study. The specific research question is: Can the observance of the laws on the roads be increased through increased traffic control and/or through more stringent sanctions? The question is delimited to speed, seat belt use and sobriety. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The thesis thus operates using three fundamental unities of analysis: speed, seat belt use and sanction. The question will be answered using five main instruments. Firstly, it concerns a theoretical model of analysis developed for the study, which has been used in the design of the empirical analyses as well as in the analysis of empirical results. Secondly, the investigation originates from a description of the law and the authorities that are administrators of justice in the field. Thirdly, the results from an empirical investigation are presented that was directed towards Swedish embassies around the world and that gives an illustration of how supervision and sanctions are used in other countries. Fourthly, it relates to a literature study where European research results in the field are presented. Fifthly, the results from an empirical study of social norms in Sweden are presented, which has been conducted through a survey that a thousand people responded to. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To conclude, it can be ascertained that the supervision and the sanctions are determining factors in terms of ensuring the observance of the laws on the roads. This is shown by both the literature study and the embassy study. The survey showed that the scope to improve the observance of the laws through increased supervision of the speed, seat belt and sobriety rules is decidedly broadest in the speed domain.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; If one wants to understand the reasons behind the reality that the law has not been able to ensure observance of the laws within the speed domain, one must proceed from the political action that forms the basis of Swedish road safety work. A fundamental problem is that the politicians have chosen to convey the zero vision to the authorities concerned through a concentrated proposed law, which is an exceedingly weak instrument of control. The political apparatus marks averseness and the authorities concerned turn downwards in the system directly towards the citizens to construct legitimacy. This kind of steering can in some areas be efficient and bring about positive results. But when dealing with an area where a gap has developed between the social norm system and the legal system, it is rather a counterproductive form of steering. When the authorities responsible for implementing the legislation must turn towards the public to seek support for their actions, it is clearly difficult to come to the conclusion of pressuring the public to act against their will. The legislation says one thing and the social norms another and the authorities concerned lack clear signals from both political quarters and from the public.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ccceeace-7d18-4348-bb49-76e81ceaad26</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Ahandling_slutgiltig_version.pdf">https://portal.research.lu.se/files/3196369/1149635.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5067675</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>regelefterlevnad</topic> <topic>efterlevnadskontroll</topic> <topic>juridik</topic> <topic>trafikbestämmelser</topic> <topic>hastighet</topic> <topic>bilbälte</topic> <topic>rattfylleri</topic> <topic>nykterhet</topic> <topic>accidens</topic> <topic>TPB</topic> <topic>essens</topic> <topic>social kontroll</topic> <topic>prevention</topic> <topic>normer</topic> <topic>trafik</topic> <topic>nollvision</topic> <topic>Rättssociologi</topic> </subject> <subject authority="lup"> <topic>Work Sciences</topic> <topic>Law</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in Sociology of Law</title> </titleInfo> <identifier type="issn">1403-7246</identifier> <identifier type="isbn">91-7267-271-4</identifier> <identifier type="oldLupId">1149630</identifier> <part> <detail type="volume"> <number>28</number> </detail> <extent unit="pages"> <total>244</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-06-05T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>ccceeace-7d18-4348-bb49-76e81ceaad26</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:09:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:09:38+02:00</recordDateApproved> </recordInfo> </mods>

There are two major types of stroke: ischemic and hemorrhagic stroke. Both are associated with disruption of blood flow to a part of the brain with rapid depletion of cellular energy and oxygen, resulting in ionic disturbances and eventually neuronal cell death [3]. The pathologic process that develops after stroke is divided into acute (within hours), sub-acute (hours to days), and chronic (days to months) phases [4, 5]. Obviously, the most effective therapy requires the earliest possible intervention e.g. with removal of a thrombus. However, no specific treatment, apart from thrombolysis, that acts effectively to protect the neurons during the acute phase has yet been developed. &lt;br/&gt;&lt;br&gt; Experimental and clinical data show an acute and prolonged inflammatory response in the brain after a stroke. Several investigators have reported that inflammation evolves within a few hours after stroke, and plays an important role in the development of the cerebral lesions [6]. This inflammatory reaction involves activation of resident cells (mainly microglia), infiltration and accumulation of various inflammatory cells (including neutrophils, leukocytes, monocytes, macrophages), and production of pro-inflammatory mediators in the injured brain areas [6, 7]. It has been established that the inflammatory reaction triggered by stroke affects not only the neuronal tissue itself but has impact also on the cerebral arteries [7].&lt;br/&gt;&lt;br&gt; Stroke is a vascular disease and despite extensive research in the area, the physiology and pathophysiology of the neurovascular unit, the complex network of endothelial cells, smooth muscle cells, inflammatory cells and mediators are not fully understood, which is necessary in order to develop effective therapies. The aim of the present thesis was to examine the role of pro-inflammatory mediators in cerebrovascular pathophysiology following stroke. The main focus was directed towards the expression and production of cytokines and inducible nitric oxide synthase (iNOS), the activation of matrix metalloproteinases (MMPs) and mitogen activated protein kinase (MAPK) pathway because microarray work [8] and published data [9] primarily pointed at these. These parameters and the relationships between them were studied in the cerebrovascular walls after ischemic and hemorrhagic strokes.&lt;br/&gt;&lt;br&gt; This study lends further support to the view that inflammatory mediators are important contributing factors in brain injury after stroke. It provides evidence that blocking the intracellular signaling pathways involved in the transcription of these mediators may have therapeutic potential, as it may prevent or at least attenuate the inflammatory processes elicited by stroke.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ischemic stroke&lt;br/&gt;&lt;br&gt; Ischemic stroke is the most common type of stroke (85% of cases). It is caused by a transient or permanent occlusion of a cerebral artery most often by a thrombus or an embolus [10, 11]. When an ischemic stroke occurs, blood flow to an area of the brain is reduced and the brain cells are starved of oxygen and nutrients, which quickly leads to neuronal cell death and the development of an infarct. The infarct region is divided into two parts: 1) A central part or an ischemic core, where the neurons die and have no chance to survive without rapid reperfusion. 2) A peripheral area or an ischemic penumbra, which surrounds the core [12]. Cells in the penumbra are impaired and cannot function due to compromised metabolism, but do not die immediately and have therefore become a prime target for neuroprotective treatments [13-15]. A number of neurochemical and pathophysiological events are triggered within the ischemic penumbra. As a result of energy depletion, there is disruption of ion homoeostasis, excessive release of excitatory neurotransmitters such as glutamate, calcium channel dysfunction, generation of oxidative stress and free radicals, activation of stress signaling, cell membrane disruption, inflammation, ultimately leading to necrotic and apoptotic cell death [1, 4, 15, 16].&lt;br/&gt;&lt;br&gt; The effect of ischemia on brain cells results not only in loss of structural integrity of brain tissue but affects also blood vessels, partly through the activation of inflammatory events and excess production of vasoconstrictor substances and increased receptor expression [17]. The early inflammatory response, which often is associated with the blood vessels, starts immediately or a few hours after the onset of the ischemia and contributes to the irreversible damage [18-21]. Currently, there are two major ways used for treating ischemic stroke: (i) Dissolution of the clot in the occluded artery by a thrombolytic drug, rt-PA (recombinant tissue-plasminogen activator) [22] and, (ii) administration of neuroprotective agents [23]. Treatment with rt-PA is limited by time and should be administered within 4.5 hours after the onset of stroke to reduce the risk of hemorrhagic transformation [24, 25]. Moreover, rt-PA is associated with the risk of disruption to the blood-brain barrier (BBB) which is due to activation of matrix metalloproteinases [26]. Despite intense research, the results obtained with neuroprotective drugs in clinical trials have not revealed positive results [27, 28].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hemorrhagic stroke&lt;br/&gt;&lt;br&gt; Hemorrhagic stroke (15% of all strokes) is often associated with hypertension, and is due to the rupture of an arterial aneurysm or a vascular malformation [1, 29]. Hemorrhagic stroke is divided into two categories: intracerebral and subarachnoid hemorrhage. Intracerebral hemorrhage (ICH) is due to the rupture of a small artery (arterioles) which bleeds within the brain tissue. It is often associated with chronic high blood pressure and the symptoms often begin with severe headache. Subarachnoid hemorrhage (SAH) occurs when an artery or an arterial aneurysm on the surface of the brain ruptures and bleeds into the space between the pia mater and the arachnoid (subarachnoid space) [1].&lt;br/&gt;&lt;br&gt; The most common cause of the SAH is the spontaneous rupture of an arterial aneurysm. This is associated with acute rise of the intracranial pressure (ICP), reduction of cerebral blood flow (CBF), rapid discharge of blood into the basal cisterns, and delayed cerebral ischemia (DCI), each of which may be fatal. The SAH is most common in women and younger people (below 55 years old). Around 50-70% of patients with SAH die or suffer severe disability, and is the cause of up to 10% of all strokes [30-33].&lt;br/&gt;&lt;br&gt; The disease is biphasic, with an early/short-lived phase that occurs immediately after SAH with a reduction in CBF, followed by a chronic or prolonged phase which is characterized by a varying degree of pathological contraction of cerebral arteries, known as vasospasm [34, 35]. The vasospasm (narrowing of arteries) typically occurs within 5-15 days after SAH and is present in approximately one-third of patients and is accompanied by DCI [36, 37]. It can occur not only at the site of the hemorrhage, but also in brain arteries at a distance from the bleeding. The narrowing of the cerebral vessel lumen leads to reduction in local blood flow and in cerebral metabolism, causing severe cerebral ischemia, with increase in mortality of 1.5-3 folds during the first two weeks after SAH [37-39]. Despite intense research, the pathogenesis of DCI after SAH is not well understood and no specific pharmacological treatment is available.&lt;br/&gt;&lt;br&gt; Current treatment recommendations involve management in an intensive care unit. The blood pressure is maintained with consideration to the patient’s neurologic status. In addition, calcium channel blockers, endothelin-1 receptor antagonists, hemodynamic management and endovascular treatment are also used, but these treatments are expensive, time-consuming and only partly effective [40]. &lt;br/&gt;&lt;br&gt; Many theories have been advanced to explain the mechanisms responsible for vasospasm and DCI that occur after SAH such as, endothelial damage [41-43], enhanced smooth muscle cell (SMC) contractility, morphologic changes in vessel walls [44], enhanced levels of free radicals [45-47], increased production and release of potent vasomotor substances such as endothelin-1 (ET-1) and angiotensin II (Ang II) [48, 49], local inflammation and immunological reactions in the vascular wall [50-52]. Yet, the exact mechanisms underlying the vasospasm and the DCI remain unknown [53]. &lt;br/&gt;&lt;br&gt; There is evidence that the amount of blood in the subarachnoid space is related to development of vasospasm [54]. Oxyhemoglobin from extravasated blood may be an important trigger of vasospasm and DCI after SAH [55-57] by inducing inflammation [50, 58]. It may in addition correlate with structural damage to the vessel wall [59], release of spasmogenic substances, and inhibition of endothelium dependent relaxation [60, 61]. It is suggested that the extravasated blood could induce generation of free radicals that subsequently may exert a direct local toxic effect on the cerebral arteries [62, 63].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; G-protein coupled receptors following stroke&lt;br/&gt;&lt;br&gt; Recently, a novel aspect of the pathophysiology of stroke has been suggested, namely that the upregulation of vasoconstrictor receptors in the cerebral arteries after stroke may be an important mechanism in the development of the final damage [64]. Vasoconstrictor receptors such as those of angiotensin II receptor type 1 (AT1) and endothelin-1 receptor type B (ETB) belong to the seven transmembrane G-protein coupled receptor (GPCR) family [65-67]. They are upregulated in the SMCs of cerebral vessels within and associated with the ischemic region after focal ischemic stroke [68] and after SAH [69]. This results in enhanced contractility of the vessels, which further impairs local blood flow and aggravates tissue damage. Importantly, the receptor ligands (angiotensin II and endothelin-1) are formed in the cerebrovascular endothelium. In addition, contractile responses mediated by AT1 and ETB receptors were found to be increased in SMCs of human cerebral arteries after organ culture [70]. Experimental stroke induces upregulation of cerebrovascular contractile receptors in the SMCs which are caused by increased receptor gene transcription induced via activation of specific intracellular signaling pathways (such as MEK-ERK1/2 and PKC pathways) [64]. Importantly, inhibition of these signaling pathways prevents the receptor upregulation, reduces infarct volume after ischemic stroke and improves neurological score and CBF after SAH [71, 72]. This may indicate that the increased cerebrovascular contractility caused by the upregulated receptors contributes to worsening of the brain damage. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Inflammation in general and following stroke &lt;br/&gt;&lt;br&gt; Inflammation is the body&apos;s defense against injurious factors and foreign antigens, e.g., trauma, infection and toxins, and is considered to be both a beneficial and a detrimental element of a pathological process. It is a complicated and multifaceted response, characterized by acute and chronic phases [73, 74].&lt;br/&gt;&lt;br&gt; Among many mechanisms involved in the pathogenesis of stroke, inflammation is increasingly recognized as a key factor. However, all the mediators of the inflammatory response have not been clearly identified [6, 75-77]. There is evidence to suggest that inflammation and immune responses are involved in all three stages of the ischemic cascade, from the acute intravascular process triggered by the interruption of the blood supply to the parenchymal processes that lead to brain damage and subsequently to tissue repair. The early inflammatory response contributes to the ischemic injury, whereas late responses may represent endogenous mechanisms of recovery and repair [78] (Figure 1). When there is a switch from detrimental to beneﬁcial effects might depend on the strength and the duration of the stroke and knowledge about the mechanisms involved is crucial for determining the time-window for effective pharmacotherapy [79].&lt;br/&gt;&lt;br&gt; As mentioned above, reduction in CBF after stroke can result in energy depletion and subsequent neuronal cell death. This triggers an immune response that results in activation of a variety of inflammatory cells and molecules [51, 80, 81]. In the acute phase (minutes to hours), extravasated blood following SAH (or following reperfusion after arterial occlusion in transient ischemia) induces generation of reactive oxygen species (ROS). They may stimulate ischemic cells to produce inflammatory molecules such as cytokines and chemokines which in turn may activate microglial cells and increase leukocyte infiltration. These produce more cytokines, causing an increase in adhesion molecules, which are normally required for the adherence and accumulation of leukocytes and neutrophils to vascular endothelial cells and infiltration of brain parenchyma. In the sub-acute phase (hours to days), increased activation of inflammatory cells results in further production of pro-inflammatory mediators including more cytokines, extracellular MMPs, as well as iNOS which generates nitric oxide (NO) and more ROS [79, 82]. The intravascular accumulation of leukocytes and of platelets results in occlusion of microvessels, leading to hypoxia and further increases in levels of ROS [83, 84]. Activation of mast cells and macrophages can in turn lead to release of histamine (a strong vasoactive substance) and production of more cytokines and proteases [85]. In addition, degradation of extracellular matrix components by MMPs (mostly MMP-9) leads to BBB disruption which contributes to secondary brain damage by releasing serum and blood elements into the brain tissue resulting in vasogenic brain edema and post-ischemic inflammation [83]. &lt;br/&gt;&lt;br&gt; Disruption and permeability of the BBB can be either transient or permanent depending on severity of the insult. Permanent disruption is associated with endothelial swelling, astrocyte detachment and blood vessel rupture in the ischemic area, while transient BBB disruption is caused by endothelial hyperpermeability to macromolecules in the penumbra area. This follows a biphasic pattern with an initial opening 2-3 hours after the onset of the insult and a second opening 24-48 hours after reperfusion leading to edema and increased intracranial pressure. All these events involve pro-inflammatory cytokines, adhesion molecules and production of MMPs [86, 87]. &lt;br/&gt;&lt;br&gt; Cerebral blood vessels are the first to be exposed to the ischemic insults and their reaction to injury sets the stage for the inflammatory response. Post-ischemic inflammation thus involves activation of microglial and endothelial cells accompanied by migration of peripheral circulating inflammatory cells into the brain such as leukocytes, neutrophils, platelet, mast cells and macrophages. These events amplify signaling along inflammatory cascades increasing the accumulation of toxic molecules that enhance the secondary damage leading to more cell stress, edema, hemorrhage and finally cell death (Figure 1) [76, 79, 84]. &lt;br/&gt;&lt;br&gt; On the other hand, many pro-inflammatory mediators play a positive role in late stage of stroke. For example, MMPs have been reported to promote brain regeneration and neurovascular remodeling in the later repair phase [79, 88, 89]. Moreover, macrophages and microglial cells also contribute to tissue recovery by scavenging necrotic debris, by producing anti-inflammatory cytokines and by facilitating plasticity [90] (Figure 1). Yet, despite these beneficial effects there is evidence that administration of anti-inflammatory drugs may reduce infarct volume and improved outcomes in animal models of stroke [91]. On the other hand, to date, clinical trials with anti-inflammatory agents have not been able to demonstrate improved clinical outcome [92, 93]. &lt;br/&gt;&lt;br&gt; With better knowledge about which cells and molecules that participate and which mechanisms regulate the inflammatory reactions triggered by cerebral ischemia, it may be possible to identify novel targets for suppression of inflammation following cerebral ischemia and thereby develop more effective stroke therapies.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Figure 1. Main inflammatory pathways that respond to injury after a stroke. The generation of ROS and free radicals that occur after stroke triggers inflammatory responses. This involves activation of cytokines and chemokines which leads to activation of inflammatory cells such as microglia and leukocytes causing more production of inflammatory mediators (cytokines, iNOS, MMPs and more ROS) which then lead to brain edema, hemorrhage and cell death. Thus, these early inﬂammatory responses contribute to ischemic injury, whereas late responses may represent endogenous mechanisms of recovery and repair through activation of anti-inflammatory cytokines, scavenging necrotic debris by microglia and neurovascular remodeling by MMPs. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Major inflammatory mediators in cerebral ischemia&lt;br/&gt;&lt;br&gt; In this present thesis, I have studied the expression of some of the major cytokines (IL-1ß, IL-6, TNF-α, TNF-R1 and R2), of MMP-9 (BBB associated) and of iNOS (potential toxic molecule) in cerebral vessel walls. Increased levels and activation of these factors may lead to exacerbation of vasoconstriction, resulting in decreased CBF and enhanced neuronal damage following a stroke.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Cytokines&lt;br/&gt;&lt;br&gt; Cytokines are recognized as small proteins, generally associated with inflammation, immune activation, cell differentiation and hematopoiesis [94]. Most cytokines are pleiotropic and have multiple biologic activities that generally act over a short distance, during short periods of time and at low concentrations. They are produced and expressed by different cell types such as astrocytes, macrophages, monocytes, microglia, platelets, endothelial and smooth muscle cells, neurons, fibroblasts and neutrophils [52, 95, 96]. Normally, they have a beneficial role, but when their expression increases in an imbalanced fashion they become detrimental [97]. Evidence for the involvement of cytokines in the pathology following stroke comes from the detection of their high levels in CSF and plasma of patients [98, 99]. It is thought that increased production and activation of such cytokines in vessel walls after cerebral ischemia/reperfusion may facilitate and expand the ischemic core by inducing secondary brain damage (brain swelling, impaired microcirculation, hemorrhage and inflammation) that typically develops after a delay of hours or days after the original ischemia, trauma or SAH [100]. It is well known that cytokines are involved in the upregulation and activation of adhesion molecules, MMPs, leukocytes, microglial, increased leukocyte-endothelium interaction and increase in vasoconstrictor substances like ET-1 following cerebral ischemia [52, 76, 101]. Tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1ß (IL-1ß) are the main cytokines which initiate inflammatory reactions and induce expression of other cytokines and inflammatory mediators after stroke. Ischemic brain has been shown to produce increased levels of TNF-α, IL-6 and IL-1ß, which are considered as a part of the damaging response [102]. Inhibiting the expression of these pro-inflammatory cytokines has been reported to reduce brain infarct size in animal models of stroke [103]. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; TNF-α&lt;br/&gt;&lt;br&gt; TNF-α is a pleiotropic cytokine and exists as either a transmembrane or soluble protein. It is involved in the disruption of the BBB, as well as in inflammatory, thrombogenic and vascular changes associated with brain injury [104]. This cytokine promotes inflammation by stimulation of acute-phase protein secretion, enhances the permeability of endothelial cells to leukocytes, and the expression of adhesion molecules and other cytokines into the ischemic area [105, 106]. In addition, it has been suggested to stimulate angiogenesis after cerebral ischemia through induced expression of angiogenesis-related genes [107, 108]. It is known as a strong immunomediator, which is rapidly upregulated early in neuronal cells in and around the ischemic penumbra, and is associated with neuronal necrosis or apoptosis [105]. TNF-α effects are mediated via two receptors, TNF-R1 and TNF-R2, on the cell surface [109]. TNF-R1 is expressed on all cell types, can be activated by both membrane-bound and soluble forms of TNF-α and is a major signaling receptor for TNF-α. The TNF-R2 is expressed primarily on endothelial cells, responds to the membrane-bound form of TNF-α, and mediates limited biological responses [109]. There is evidence that TNF-α and its receptors may activate nuclear factor-κB (NF-κB), a transcription factor whose activation leads to expression of several genes involved in inflammation and cell proliferation [110-112]. In addition, NF-κB is involved in signaling cell death as well as cell survival, and the balance between these signals determines the toxic degree of TNF-α [112, 113]. &lt;br/&gt;&lt;br&gt; TNF-α appears then to be not only neurotoxic but also neuroprotective. Increased TNF-α levels have been observed in brain tissue, plasma and CSF in several CNS diseases such as Alzheimer’s, multiple sclerosis and Parkinson’s [114-116]. Accordingly, a recent study demonstrated that blocking TNF-α significantly reduced infarct size after both permanent and transient MCAO, suggesting the involvement of TNF-α in neuronal cell damage [104]. In contrast, there is evidence to suggest that brain injury after ischemia becomes worse in mice lacking TNF-R1, suggesting that TNF-α mediates neuroprotection through this receptor [117]. The function of TNF-α appears to differ between brain regions. TNF-α released for instance in the striatum is considered as neurodegenerative, while release in the hippocampus has been suggested to promote neuroprotection [112]. Several investigators have suggested that the detrimental effects are activated in the early phase of the inflammatory process whereas the beneficial effects take place in the later phases [79].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; IL-6&lt;br/&gt;&lt;br&gt; IL-6 is an endogenous and hematopoietic cytokine that plays multiple roles in the central nervous system during infection and after traumatic injuries. It is involved in induction of B-cell differentiation and helps to attract T-lymphocytes into the brain, contributing to exacerbation of the inflammatory response [79]. To exert its biological effects, IL-6 binds to its receptor, IL-6Rα, which can be either soluble or membrane-bound [118]. IL-6 is often induced together with TNF-α and IL-1ß in different conditions, and circulating IL-6 plays an important role in the induction of acute phase reactions [119]. Several studies have revealed that the expression of IL-6 is detected at an early time point, 4-6 hours after onset of ischemia, and at a later point at 24-48 hours, and that it remains detectable for up to 14 days [120, 121]. The level of IL-6 in CSF is significantly increased from days 3-6 in patients with vasospasm compared to patients with no symptoms of vasospasm, suggesting that IL-6 might be involved in inducing CVS after SAH [122]. In addition, in animal models of stroke, there is an enhanced expression of IL-6 in neuronal cells [123]. However, the exact role of IL-6 in cerebral ischemic is still unclear. For example, the high levels of IL-6 in plasma of patients with acute brain ischemia, are strongly associated with stroke severity and long-term clinical outcome [124]. On the other hand, IL-6 deficient mice show similar infarct size compared to the wild type, suggesting that it does not participate in ischemia pathogenesis [125].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; IL-1ß&lt;br/&gt;&lt;br&gt; IL-1ß is a member of the IL-1 family and is rapidly produced in the brain after cerebral ischemia [105, 126]. IL-1ß is involved in development of brain damage following cerebral ischemia and blockade of IL-1ß converting enzyme activity, reduced infarct size and improved behavioural deficit [127]. IL-1ß acts by binding to its two transmembrane receptors, type I IL-1 receptor (IL-1R1) and type II IL-1 receptor (IL-1R2) initiating signaling cascades that result in expression of inflammatory genes [128-130]. In addition, IL-1ß plays an important role in the acute stress-induced worsening of behavioural and neurological outcomes and increased infarct size after MCAO in rat [131]. A previous study indicated that IL-1ß expressed in vascular SMCs after SAH, mediates SMC apoptosis and results in enhanced aneurysm formation [132]. Several investigations have shown that IL-1ß, IL-6 and TNF-α follow approximately the same time course of expression after both global and focal cerebral ischemia. Thus, there is an early increase in the levels of TNF-α (1 h), IL-6 and IL-1ß (3-6 h) and a later increase at 2 days post-MCAO, which have been observed in cerebral cortex, striatum and hippocampus [121, 133, 134].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Matrix Metalloproteinases&lt;br/&gt;&lt;br&gt; The MMPs represent a family of zinc-dependent proteolytic enzymes with the ability to break down extracellular matrix (ECM) proteins and to cleave other non-ECM molecules ranging from growth factors, cytokines and binding proteins to cell surface receptors [135]. MMPs are involved in extracellular matrix remodeling, wound healing and angiogenesis. They are normally found in the cytosol in an inactive form, but when cleaved by proteases, such as plasmin or other MMPs, they convert to their active form [136]. The proteolytic activity of MMPs is tightly controlled by tissue inhibitors of MMPs (TIMPs). TIMPs are specific endogenous molecules, which by binding to pro-MMPs inhibit the activation of MMPs. Imbalance between production of MMPs and TIMPs plays an important role following stroke [137, 138]. Pfefferkorn and Rosenberg showed in an experimental stroke model that inhibition of MMP reduces infarct volume, brain edema and hemorrhage [139], supporting the notion that MMPs mediate the degradation of the neurovascular matrix and thereby promoting injury of the BBB.&lt;br/&gt;&lt;br&gt; Increased expression of MMP levels may contribute to inflammation, particularly those of MMP-2 and MMP-9 which have been shown to be upregulated in cerebral ischemia, however at different time points [140, 141]. Permanent MCAO in rats resulted in production of MMP-2 peaking at 5 days post-ischemia while MMP-9 peaked at 24-48 hours when the BBB was maximally opened. It was concluded that MMP-9 had a more significant role as compared to MMP-2 [141-144]. At the same time, MMPs seem to play yet another role in the later phase of cerebral ischemia, being involved in vascular plasticity and recovery through increase of vascular endothelial growth factor (VEGF) signals [145]. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; MMP-9&lt;br/&gt;&lt;br&gt; MMP-9 or gelatinase B is a pro-inflammatory protease that is produced during inflammatory responses by astrocytes, microglia, endothelial cells, neutrophils and macrophages. MMP-9 activates both AP-1 and NF-κB transcription factors which in turn activate pro-inflammatory cascades [146]. MMP-9 is able to degrade major components of the endothelial basal lamina (type IV collagen, laminin and fibronectin), playing an important role in the disruption of the BBB thereby contributing to the development of edema following ischemia/reperfusion [142, 143, 147]. In support, it has been reported that administration of a MMP-9 inhibitor prevented the degradation and abolished the BBB disruption after focal ischemia in rat [142]. MMP-9 is also expressed in human brain tissue after ischemic and hemorrhagic stroke [148]. Furthermore, degradation of basal lamina through activation of MMP-9 after cerebral ischemia leads to loss of astrocytes and endothelial cell contacts, resulting in hemorrhagic transformation [149]. Besides this, an early increase in MMP-9 expression has been observed in microvascular walls, which has been suggested to be the primary cause of microvasular hemorrhage after cerebral ischemia [138]. Accordingly, MMP-9 deficient animals showed a smaller infarct area in an experimental stroke model, as compared to wild type controls [150]. Additionally, it has been reported that the levels of MMP-9 in plasma appear to correlate with infarct volume and severity of stroke [151]. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; iNOS&lt;br/&gt;&lt;br&gt; Another potent biological molecule that is expressed during inflammatory reactions in the CNS is nitric oxide (NO) which is induced by nitric oxide synthase (NOS) [152]. NO is an important signaling molecule, involved in numerous physiological processes such as neuronal communication, host defense and regulation of vascular tone. Three different isoforms of NOS exist: neuronal NOS (nNOS), endothelial NOS (eNOS) and the inducible form (iNOS). nNOS and eNOS are constitutively expressed and calcium-dependent, whereas iNOS is expressed after immunologic challenge and neuronal injury and is calcium-dependent under most circumstances [153]. &lt;br/&gt;&lt;br&gt; Activation of iNOS produces toxic levels of nitric oxide and is considered one of the key inflammatory mediators produced by different cells [76, 154]. There is evidence that iNOS can enhance glutamate release, resulting in ATP depletion in the ischemic infarct area after transient focal cerebral ischemia in rats [155]. In addition, it has been reported that iNOS is not present in the CNS under physiologic conditions, but its expression can be stimulated by cytokines [51]. The activity of iNOS is strongly linked to that of COX enzymes because of the interaction between the two systems. There is evidence that the production of iNOS increases with the activity of COX-2, which results in generation of more free radicals [52]. Moreover, iNOS may in addition cause DNA damage in cerebral ischemia through the formation of peroxynitrite [156]. &lt;br/&gt;&lt;br&gt; A previous study has revealed that iNOS expression is significantly increased in vascular endothelial and smooth muscle cells at 7 days post-SAH, and that its intensity is greatest in animals with angiographic vasospasm [157]. Furthermore, the mRNA level of iNOS is increased mostly in vascular tissue at 1-7 days in different experimental SAH models [158]. Expression of iNOS has also been reported in both permanent and transient MCAO at 12-48 hours post-ischemia in inflammatory cells of the brain parenchyma and in cerebral blood vessels [159, 160]. The involvement of iNOS in cerebral ischemia is confirmed by the observation that mice lacking the iNOS gene have significantly reduced infarct volumes compared with wild-type controls [161]. Accordingly, administrations of iNOS blockers after cerebral ischemia attenuate the damage, decrease the infarct volume and improve neurological outcome [162, 163]. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Intracellular Signaling&lt;br/&gt;&lt;br&gt; Cerebral ischemia activates several cell signaling pathways that are crucial for cell survival or damage, initiating complex cascades of events at genomic, molecular and cellular levels in all types of cells in the CNS. Inflammation, which occurs after both ischemic and hemorrhagic stroke, is very important in this context and may participate as a further enhancer in the ischemic cells [164]. Studies of signal transduction pathways that regulate the inflammatory genes have mostly focused on mitogen activated protein kinases (MAPKs), one of the cascades activated in response to cerebral ischemia [165]. &lt;br/&gt;&lt;br&gt; In this thesis, the attention has been directed towards evaluation of the role of Raf-MEK-ERK1/2 signaling transducers in regulating the expression of pro-inflammatory mediators in cerebral vessels following both ischemia and hemorrhagic stroke. The work provides some clues to explaining beneficial effects observed with inhibitors of these cascades in experimental models. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Mitogen activated protein kinases&lt;br/&gt;&lt;br&gt; MAPKs are involved in the transduction of cellular responses, mediating signaling from the extracellular environment to the nucleus and other intracellular targets [166, 167]. In response to extracellular stimuli, MAPKs regulate a broad range of intracellular activities from metabolism, motility, inflammation, differentiation and proliferation to cell death and survival [168]. The transduction of signals is made through activation of protein kinases and protein phosphatases [168, 169]. The MAPK family consists of three major groups, including extracellular signal-regulated kinase (ERK), p38 and stress-activated protein kinase c-Jun N-terminal kinase (SAPK/JNK). Each MAPK signaling pathway contains a three-tiered kinase cascade comprising a MAPKKK, that can activate MAPKK, which in turn activates and phosphorylates MAPKs [170]. Activation of MAPK pathways regulates the activity of a number of transcription factors that are present in the cytoplasm or the cell nucleus, such as Elk-1, ATF-2, C-Myc, NF-κB, and AP-1 components, as well as c-Fos and c-Jun [170, 171]. Activation of these transcription factors leads in turn to the expression of target genes, resulting in biological responses. It has been demonstrated that various MAPKs have overlapping functions, with the same transcription factor sometimes being activated by two or more MAPKs [172]. ERK1/2 is thus involved in differentiation, proliferation, meiosis, learning and memory in nerve cells and is activated by oxidative stress and mitogenic stimuli such as growth factors, cytokines and GPCRs [173-175]. In addition to the ERK pathway, the p38 and JNK pathways have been demonstrated to be involved in inflammation, cell survival and apoptosis, and can be activated by inflammatory cytokines and changes in shear stress. These kinases are activated by phosphorylation on both threonine and tyrosine residues, which may phosphorylate intracellular enzymes and transcription factors [172, 176]. The balance between ERK and p38-JNK has been suggested to regulate cell fate, mediating survival or death [177]. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; MAPK and inflammation in cerebral ischemia&lt;br/&gt;&lt;br&gt; As mentioned before, cerebral ischemia is a pathophysiological condition caused by decreases in blood supply to the brain that results in deprivation of oxygen and glucose, leading eventually to cell death, inflammation and tissue repair [178]. In response to inflammatory stimuli that activate macrophages and initiate leukocyte infiltration, intracellular signaling pathways are activated and carry the signals needed to further activate the production of inflammatory mediators [179]. Cytokines such as TNF-α, IL-1ß and IL-6 can act as intracellular messengers because they have low molecular weights [180]. They act through binding to their respective receptors and/or Toll like receptors. Activation of the receptors triggers major intracellular signaling pathways, leading to activation of transcription factors such as NF-κB and AP-1, which in turn produce more cytokines involved in secondary damage [179]. Regulation of the expression of these genes by MAPK signaling, especially via ERK1/2, plays important roles in cerebra ischemia [167]. &lt;br/&gt;&lt;br&gt; Several investigators have suggested a role for the ERK pathway in the regulation of cytokine expression following cerebral ischemia. For example, studies have shown that TNF-α can increase the permeability of the BBB via activation of the ERK1/2 pathway and increase the expression of TNF-R1 and TNF-R2. Treatment with a MEK1/2 inhibitor inactivates this signaling pathway and decreases the expression of the TNF receptors [181, 182]. However, it has been suggested that the main biological response to p38 activation involves the production and activation of inflammatory genes such as cytokines, COX2 and collagenase-1, while, inhibition of p38 may reduce pro-inflammatory cytokines in several inflammatory cells [179, 183]. &lt;br/&gt;&lt;br&gt; Activation of all three major MAPK pathways has been reported in experimental cerebral ischemia [9, 175, 184, 185] and activation of ERK1/2 is reported in humans after ischemic stroke [186]. Activation of JNK and p38 appears to be detrimental after a stroke and their inhibition decreases infarct size and prevents neuronal apoptosis [177, 187-189], while ERK1/2 activation can be both beneficial and detrimental [190]. &lt;br/&gt;&lt;br&gt; There is evidence pointing at the activation of ERK1/2 in cerebral arteries after MCAO [72], after SAH [49] and in cultures [185]. In addition, several studies have reported on the involvement of the MEK/ERK/MAPK pathway in the regulation of CVS after experimental SAH [191, 192]. It has been suggested that activation of the ERK1/2 pathway increases neurological damage by increasing ROS and oxidative stress-related cell death, promoting inflammation after stroke [190]. ERK1/2 activity may also stimulate inflammation by upregulation of IL-1ß, which results in necrosis [180]. &lt;br/&gt;&lt;br&gt; Wang and co-workers revealed that the activation of ERK1/2 in the brain following ischemia/reperfusion is associated with cell death and brain injury while inhibition of ERK1/2 by a specific MEK1/2 inhibitor provided neuroprotection in cerebral ischemia through suppression of IL-1ß expression [193]. Administration of inhibitors of the MEK/ERK1/2 pathway has been found to attenuate ischemic injury and improve neurological outcome [68, 194, 195]. On the other hand, ERK1/2 activity may also block apoptosis by increasing the level of the anti-apoptotic protein BCL-2 or by inhibiting the pro-apoptotic protein Bad [168]. Moreover, it has been reported that ERK1/2 mediates protection after cerebral hypoxic-ischemic injury through activation of neurotrophins such as brain derived neurotrophic factor (BDNF), resulting in survival of neurons in the neonatal brain [196]. According to earlier studies, the protein kinase ERK1/2 is activated in the early phase after stroke [71]. &lt;br/&gt;&lt;br&gt; Here, in this work, we suggest that this activation is probably an early “switch-on” mechanism involved in the increased release or formation of vasoconstrictor receptors, cytokines and of other mediators. Cytokine stimulation, in turn, activates p38 and JNK pathways which results in induction of more inflammatory genes, causing more damage. Therefore, early inhibition of this pathway may provide novel interesting targets for anti-inflammatory therapy following stroke (Figure 2).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Figure 2. Regulation and production of pro-inflammatory mediators through early activation of the ERK1/2 MAPK pathway, which is stimulated by stress, cytokines and CGRP.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hypothesis&lt;br/&gt;&lt;br&gt; We hypothesize that the increase in expression of cerebrovascular pro-inflammatory mediators that is seen after cerebral ischemia occurs via increased inflammatory gene transcription induced via activation of MAPK-MEK-ERK1/2 signaling pathway. This results in reduced CBF, larger brain damage and worsened neurological function. By blocking this signaling pathway in time, it will prevent the enhanced transcription of inflammatory genes and is associated with improved outcome after stroke. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; AIMS&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The general aim of this thesis is to investigate the role of pro-inflammatory mediators and their regulation in the wall of cerebral vessels following cerebral ischemia. More specifically:&lt;br/&gt;&lt;br&gt; • To investigate the expression of MMP-9 and TIMP-1 in cerebrovascular SMC following focal cerebral ischemia and to determine if their expression is regulated via the MEK/ERK pathway.&lt;br/&gt;&lt;br&gt; • To investigate the expression of pro-inflammatory cytokines in the walls of cerebral vessels after MCAO and to compare the inhibition of the inflammatory reaction with 1) a specific MEK1/2 inhibitor (U0126) to block transcription, and 2) a combined blockade of the AT1 and ETA receptors. &lt;br/&gt;&lt;br&gt; • To determine if the time-course and upregulation of pro-inflammatory mediators in the walls of cerebral arteries and microvessels after SAH is associated with the MEK-ERK1/2 pathway.&lt;br/&gt;&lt;br&gt; • To investigate if treatment with specific Raf or/and MEK1/2 inhibitors given as late as 6 hours after induction of SAH would prevent the upregulation of pro-inflammatory mediators, prevent SAH-induced decrease in CBF and improve functional neurological outcome.&lt;br/&gt;&lt;br&gt; • To examine if the expression of TNF-α and TNF receptors in the wall of cerebral arteries in two in vivo models (MCAO, SAH) and in an in vitro model of isolated cerebral arteries segments (organ culture), is regulated via the MEK/ERK pathway. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; GENERAL METHODS&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Animal surgery procedure&lt;br/&gt;&lt;br&gt; MCAO model (papers I, II and V)&lt;br/&gt;&lt;br&gt; Transient middle cerebral artery occlusion (MCAO) was induced in male Wistar rats by an intraluminal filament technique described by Memezawa et al [197]. The rats were housed under controlled temperature and humidity with free access to water and food. Anesthesia was induced using 4.5 % halothane or isoflurane in N2O:O2 (70:30); thereafter the rats were kept anesthetized by inhalation of 1.5 % halothane or isoflurane on a mask. To confirm a proper occlusion of the right MCA, a laser-Doppler probe was fixed on the skull measuring regional cortical blood flow. A polyethylene catheter was inserted into a tail artery for measurements of mean arterial blood pressure (MAP), pH, pO2, pCO2, and plasma glucose. A rectal temperature probe connected to a homeothermal blanket was inserted for maintenance of a body temperature of 37 ° C during the operational procedure. An incision was made in the midline of the neck and the right common, external and internal carotid arteries were exposed. The common and external carotid arteries were permanently ligated by sutures. A filament was inserted into the internal carotid artery via an incision in the common carotid artery, and further advanced until the rounded tip reached the entrance of the right MCA. The resulting occlusion was made visible by laser-Doppler as an abrupt reduction of cerebral blood flow of about 80-90 %. Finally, the filament was fixed by a suture and the rats were allowed to wake up. Two hours after occlusion, the rats were re-anesthetized to allow for withdrawal of the filament, and subsequently achieve reperfusion as verified by laser-Doppler recording [198, 199].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; SAH model (papers III, IV and V)&lt;br/&gt;&lt;br&gt; Subarachnoid hemorrhage (SAH) was induced in male Sprague-Dawley rats by a model originally described by Svendgaard et al [200] and in detail by Prunell et al [201]. In this model, fresh and non-heparinized blood is administered into the subarachnoid space at an intracranial pressure (ICP) equal to the mean arterial pressure. The rats were anesthetized, intubated and artificially ventilated with inhalation of 0.5-1.5% halothane (paper III) or 1-2% isoflurane (paper IV) in N2O/O2 (70:30) during the surgical procedure. Respiration was monitored by regularly withdrawing blood samples to a blood gas analyzer. A temperature probe was inserted into the rectum of each rat to record the body temperature, which was maintained at 37ºC by a heating pad. An arterial catheter was placed in the tail artery to measure blood pressure and a catheter to measure the ICP was placed in the subarachnoid space. A laser-Doppler probe was placed to measure cortical cerebral blood flow (CBF). A 27G blunt cannula with a side hole facing right was placed 6.5 mm anterior to the bregma in the midline at an angle of 30º to the vertical plane placing the tip of the needle just in front of the chiasma opticum. After 30 minutes of equilibration, 250 µl of blood was withdrawn from the tail catheter and injected manually into the prechiasmatic cistern at a pressure equal to the mean arterial blood pressure. Subsequently, rats were maintained under anesthesia for another 60 minutes in order to allow the animal to recover. The ICP catheter was cut and sealed with a removable plug 2 cm from the tip. The tail catheter, the needle and the laser-Doppler probe were removed and incisions closed. The rats were then revitalized and extubated.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Drug administration &lt;br/&gt;&lt;br&gt; U0126 (papers I, II and IV)&lt;br/&gt;&lt;br&gt; U0126 is a specific MEK1/2 inhibitor that inhibits the ERK1/2 pathway by binding to and inhibiting the enzyme activity of MEK1/2, inhibiting thereby the activation and phosphorylation of ERK1/2 [180]. U0126 was used in both MCAO and SAH experimental models. In the MCAO model, 30 mg/kg body weight of U0126 (obtained from Sigma, St Louis, MI, U.S.A.) were administered intraperitoneally either immediately after starting reperfusion (0 hours) or at 6 or 12 hours after the start of reperfusion; in both cases, the first injection was followed by a second one at 24 hours. The animals were then sacrificed 48 hours after occlusion (papers I and II). In the SAH experimental model, 0.22 µg/kg body weight of U0126 were administered intracisternally in two strategies: (i) treatment started at 6 hours after SAH induction, was repeated at 12, 24 and 36 hours and animals were then sacrificed at 48 hours; or (ii) treatment started at 6 hours after SAH induction, was repeated at 12 and 24 hours and animals were sacrificed at 72 hours post-SAH (paper IV). The U0126 doses were chosen on the basis of previous studies [68, 202]. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; SB386023+b (paper III)&lt;br/&gt;&lt;br&gt; SB386023+b is a specific B-Raf inhibitor, which inhibits MAPKKK upstream of MEK/ERK1/2 pathway [203]. The substance (20 µl of a 10-6M solution; kind gift from Dr. AA Parsons, GSK; UK), were administered intracisternally. Treatment started at different time points after SAH induction (0, 6 or12 hours) with repeated injections over a period of 36 hours. Animals were subsequently sacrificed at 48 hours post-SAH. The dose of SB386023+b was chosen based on a previous study on isolated arteries [185].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Neurological evaluation (papers I, II and IV)&lt;br/&gt;&lt;br&gt; Neurological evaluations were performed for all survival MCAO and SAH animals. The MCAO animals were examined neurologically before recirculation and immediately before they were sacrificed, at 48 hours after MCAO, using an established scoring system described in Table 1 [198, 199]. A rotating pole test was used to evaluate gross sensorimotor function (integration and coordination of movements as well as balance) of SAH animals. This examined the ability of the animals to traverse a rotating pole, which was either steady or rotating at different speeds (3 or 10 rpm) [204]. The performance of the rat was scored according to the described in Table 2. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Table 1.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Score Interpretation&lt;br/&gt;&lt;br&gt; 0 No visible deficits.&lt;br/&gt;&lt;br&gt; 1 Contralateral forelimb flexion, when held by tail.&lt;br/&gt;&lt;br&gt; 2 Decreased grip of contralateral forelimb.&lt;br/&gt;&lt;br&gt; 3 Spontaneous movement in all directions, but contralateral circling if pulled by tail.&lt;br/&gt;&lt;br&gt; 4 Spontaneous contralateral circling.&lt;br/&gt;&lt;br&gt; 5 Death.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Table 2.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Score Interpretation&lt;br/&gt;&lt;br&gt; 1 Animal is unable to balance on the pole and falls off immediately.&lt;br/&gt;&lt;br&gt; 2 Animal balances on the pole but has severe difficulties crossing the pole and moves less than 30 cm.&lt;br/&gt;&lt;br&gt; 3 Animal embraces the pole with the paws and does not reach the end of the pole but manages to move more than 30 cm.&lt;br/&gt;&lt;br&gt; 4 Animal traverses the pole but embraces the pole with the paws and/or jumps with the hind legs.&lt;br/&gt;&lt;br&gt; 5&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; 6 Animal traverses the pole with normal posture but with more than 3-4 foot slips.&lt;br/&gt;&lt;br&gt; Animal traverses the pole perfectly with less than 3-4 foot slips.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Brain damage evaluation (papers I and II)&lt;br/&gt;&lt;br&gt; Coronal slices (2 mm thick) were obtained from brains of MCAO operated rats and stained by 1 % 2, 3, 5-triphenyltetrazolium chloride (TTC) dissolved in buffer solution at 37˚C for 20 minutes. Following TTC staining, normal brain tissue appeared bright red, while regions of damage were pale-white. The size of the ischemic damage was calculated as a percentage of the total brain volume calculated from the slices, using the software program Brain Damage Calculator 1.1 (MB Teknikkonsult) [72]. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Cerebral blood flow measurement (paper III)&lt;br/&gt;&lt;br&gt; The SAH rat was intubated and artificially ventilated with inhalation of 0.5% to 1.5% halothane in N2O/O2 (70:30) during the surgical procedure. The anesthesia and the respiration were monitored by regularly withdrawing arterial blood samples for blood gas analysis. A catheter to measure MABP was placed in the right femoral artery and a catheter for blood sampling was placed in the left femoral artery. This catheter was connected to a constant velocity withdrawal pump for mechanical integration of tracer concentration. Another catheter was inserted in one femoral vein for injection of heparin and for infusion of the radioactive tracer. After 30 minutes of equilibration, a bolus injection of 50 µCi of 14C-iodoantipyrine 4[N-methyl-14C] was administered intravenously and subsequently, 122 µl of arterial blood was withdrawn over 20 seconds. Thereafter, the rat was decapitated, the brain removed and chilled to -50°C. The ß-radioactivity scintillation counting was performed on the blood samples with a program that included quench correction. The 14C activity in the tissue was determined on cryo-sections of the brain. The sections were exposed to X-ray films together with 14C methyl methacrylate standards and exposed for 20-30 days. The 14C content was determined in several brain regions and CBF was calculated from the brain tissue 14C activity determined by autoradiography using the equation of Sakurada [205] and Gjedde [206].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Organ culture (paper V)&lt;br/&gt;&lt;br&gt; The organ culture has been described previously by Adner and co-workers [207]. Male Wistar rats were anesthetized with CO2 and decapitated. The brains were quickly removed and chilled in ice-cold bicarbonate buffer solution. The cerebral arteries were removed and dissected free from the brain and surrounding tissue. The artery segments were placed individually in wells with 2 ml serum-free Dulbecco’s modified Eagle’s medium (DMEM) supplemented with streptomycin (100 µg/ml) and penicillin (100 U/ml). Incubation was performed at 37°C in humidified 5 % CO2 in air for 24 or 48 hours in the presence or absence of the intracellular signal inhibitors (a NF-κB inhibitor, IMD-0354; 30 nM; the specific MEK1/2 inhibitor, U0126; 10µM, the specific B-Raf inhibitor, SB386023-b; 10µM). These substances were added to the medium in the beginning and at 24 hours of the culture. IMD-0354 was shown to specifically inhibiting the phosphorylation of IκB by IκB kinases, thus preventing NF-κB release and activation [208].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Molecular techniques&lt;br/&gt;&lt;br&gt; Real-time PCR (paper III)&lt;br/&gt;&lt;br&gt; Real time polymerase chain reaction (RT-PCR) is a sensitive method used for the detection of mRNA expression of a specific gene in a tissue homogenate. Cerebral arteries were immediately dissected out free from the brain and cleaned from connective tissue and blood. Total cellular RNA was extracted from the cerebral arteries using the Trizol RNA isolation kit according to the supplier’s instructions (Invitrogen, Taastrup, Denmark). Total RNA was determined using a Gene Quant Pro spectrophotometer measuring absorbance at 260/280 nm. Reverse transcription of total RNA to cDNA was performed using the GeneAmp RNA kit (Perkin-Elmer Applied Biosystems, USA) in a Perkin-Elmer DNA thermal cycler, using random hexamers as primers.&lt;br/&gt;&lt;br&gt; Real-time quantitative PCR was performed in a GeneAmp 5700 sequence detection system using the GeneAmp SYBER® Green kit (Perkin-Elmer Applied Biosystems, USA) with the cDNA synthesized above as template. Specific primers were designed by using the Primer Express software program and no-template controls for each primer pair were included in all experiments. The real–time PCR consists of a system that is able to evaluate the amount of DNA in each PCR cycle via the detection of a fluorescent dye binding double-strand DNA. The amount of mRNA for each gene was calculated relative to the amount of the housekeeping genes elongation factor-1(EF-1) and ß-actin, which were used as endogenous standards as they are continuously expressed in cells. For detailed description of the real-time PCR method, please see the paper III.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Immunohistochemistry (papers I-V)&lt;br/&gt;&lt;br&gt; Indirect immunofluorescence staining was used for the detection and localization of specific proteins in cerebral arteries, microvessels and surrounding brain tissue. Briefly, the cerebral arteries and surrounding brain tissue were dissected out, placed into Tissue TEK, frozen on dry ice, and sectioned into 10-µm-thick slices in a cryostat. Cryostat sections were fixed for 10 minutes in ice cold acetone and thereafter rehydrated in phosphate buffer solution (PBS) containing 0.25% Triton X-100 for 15 minutes. The tissue sections were then permeabilized and blocked for 1 hour in blocking solution and thereafter were incubated over night at 4 ˚C with the primary antibody of interest. The sections were subsequently washed with PBS and incubated with the appropriate secondary antibody conjugated with a fluorophore for 1 hour at room temperature. After washing with PBS, the slides were mounted with anti-fading mounting medium and sections were photographed with a confocal microscope at the appropriate wavelengths. The same procedure was used for the negative controls except that either the primary antibody or the secondary antibody was omitted to verify that there was no autofluorescence or unspecific labeling. Fluorescence intensity was used as a semi-quantitative measure of the level of expression of the proteins in the samples and was determined using the ImageJ software (http://rsbweb.nih.gov/ij/).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Western blot (papers I, III and V)&lt;br/&gt;&lt;br&gt; Western blotting is a method commonly used in order to identify and quantify a certain protein in a sample of tissue homogenate or extract. The cerebral arteries were harvested, frozen in liquid nitrogen and homogenized in cell extract denaturing buffer. Whole cell lysates were sonicated on ice and the supernatants were collected as protein samples. Total protein concentration was determined using a Bio-Rad DC kit (Bio-Rad, Hercules, CA, USA). Equal amounts of protein were loaded onto a gel and separated by sodium dodecyl sulfate-PAGE. Molecular weight markers were loaded on each gel for protein band identification. After separation, proteins were transferred to a nitrocellulose membrane by electroblotting. The membrane was then blocked for 1 hour at room temperature and incubated with the primary antibody of interest overnight at 4ºC, followed by incubation with a horseradish peroxidase (HRP)-conjugated secondary antibody for 1 hour at room temperature. The labeled proteins were developed using the LumiSensor Chemiluminescent HRP Substrate kit (GenScript, Piscataaway, NJ, USA). The membrane was visualized using a Fujifilm LAS-1000 Luminescent Image Analyzer and band intensity was quantified using Image Gauge Version 4.0. The levels of ß-actin were used as a control for the normalization of the target proteins and data were expressed as a percentage of control.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Statistics&lt;br/&gt;&lt;br&gt; Statistical analyses were performed using the nonparametric Kruskal-Wallis with Dunn´s post hoc test for comparison between more than two groups and Mann-Whitney test for comparison between two groups, using Graph Pad Prism v.5 (Graph Pad software, Inc., La Jolla, CA). Data were expressed as the mean ± standard error of the mean (S.E.M) and P-values less than 0.05 were considered significant.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ethics&lt;br/&gt;&lt;br&gt; For MCAO the experimental procedures were approved by the University Animal Ethics Committee in Sweden (M43-07). For SAH all procedures were carried out strictly in accordance with national laws and guidelines and were approved by the Danish Animal Experimentation Inspectorate (license no. 2066/561-1139) and the Ethical Committee for Laboratory Animal Experiments at the University of Lund.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; RESULTS AND DISCUSSION&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Cerebrovascular expression of pro-inflammatory mediators following MCAO (papers I and II)&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; MMP-9 and TIMP-1 expression &lt;br/&gt;&lt;br&gt; The BBB plays an important role in protecting the neuronal environment. Endothelial cells of brain arteries and capillaries have tight junctions, which can restrict molecules from moving between the blood and the brain. MMP-9 has been reported to be involved in the disruption of the BBB by degrading the tight junction proteins claudin-5 and occludin between the endothelial cells and extracellular matrix molecules constituting the basal lamina surrounding the endothelial cells. When the integrity of the BBB is lost, inflammatory cells and fluid can pass to the brain, causing hemorrhage, vasogenic edema and neuronal cell death [142, 209, 210].&lt;br/&gt;&lt;br&gt; There exist evidence pointing at angiotensin II and endothelin-1 increase following cerebral edema. They may induce elevated MMP-9 expression in rat vascular SMCs and astrocytes through activation of AT1 and ETB receptors after focal cerebral ischemia and in culture [211, 212]. Interestingly, administration of inhibitors towards these receptors reduced MMP-9 expression and ischemic injury [211, 212]. Therefore, the aim of paper I was to examine the early changes in the expression of MMP-9 and TIMP-1 in the walls of brain vessels at 48 hours post-MCAO. &lt;br/&gt;&lt;br&gt; Results from immunohistochemistry showed markedly enhanced expression of these proteins in the SMCs of the middle cerebral arteries (MCAs) and in associated microvessels within the ischemic region (Figure 3) and not in vessels on the contralateral side. This was confirmed with western blot analysis that showed the protein levels of MMP-9 and TIMP-1 were significantly increased in MCAs after MCAO as compared to control groups (Figure 4). The results are in agreement with a previous study that reported increased in MMP-9 mRNA levels in the MCA at 24 hours after focal ischemia [9]. Another studies confirmed the presence and increase in MMP-9 mRNA and protein levels in the ischemic region at 24 hours after MCAO with reperfusion. This was associated with reduction in tight junction proteins in cerebrovascular endothelial cells and administration of a MMP blocker and in MMP-9 knock-out animals prevented the degradation of tight junction proteins, reduced the BBB opening and vasogenic edema [142, 143]. Moreover, It has been reported that in rats with 2 hours transient MCAO, a maximally increase in MMP-9 was associated with maximal brain sucrose uptake at 48 hours after reperfusion [146]. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Figure 3. Confocal microscopy images of the MCA, cerebral microvessels (Mic.V), and surrounding brain tissue (Brain). Immunofluorescence labeling corresponding to MMP-9 (A-E) or TIMP-1 (F-J). Images represent the vehicle control group (contralateral side) (A, F), MCAO plus vehicle group (epsilateral side) (B, G), MCAO plus U0126 with start at 0 hour (C, H), with start at 6 hours (D, I) or at 12 hours (E, J) groups. There was a significant increase in MMP-9 protein levels in the smooth muscle cell layer of ischemic vessels as compared to vessels from the control group. TIMP-1 expression was upregulated in SMCs and in the proximity of the adventitia layer of ischemic vessels as compared to control vessels. Treatment with U0126 starting at zero and 6 hours, but not 12 hours after occlusion, prevented the increase in MMP-9 and TIMP-1 protein expression.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Figure 4. Western blot showing MMP-9 and TIMP-1 protein expression levels in the MCA 48 hours after MCAO using ß-actin as a loading control. Treatment with U0126 at 0 hour post occlusion decreased the MCAO-induced enhanced expression of MMP-9 and TIMP-1 proteins. Data are expressed as mean ± S.E.M., n = 4. *P &amp;lt; 0.05, **P &amp;lt; 0.01.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In addition, we showed that TIMP-1 was increased 48 hours after MCAO, probably in effort to balance the elevated expression of MMP-9 after induction of MCAO. Thus, we suggest that an imbalance between MMPs and TIMPs expression following cerebral ischemia may result in opening of the BBB and increase vessels permeability in reperfusion injury, contributing to cerebral edema and more brain damage. &lt;br/&gt;&lt;br&gt; To determine the cellular source of MMP-9 and TIMP-1, we performed co-localization studies using a SMC-actin specific antibody. MMP-9 immunoreactivity was localized to the cytoplasm in SMCs of the cerebral vessels. TIMP-1 was also localized in the SMCs of the medial layer but it was mainly located closer to the adventitia layer of the cerebral vessel walls (Figure 5). To confirm this, we performed co-localization studies using CD31 (as a marker of endothelium cells) neither MMP-9 nor TIMP-1 revealed any major co-localization with CD31; hence, the upregulation occurs in the medial layer. In addition, some vessels were studied after mechanical removal of endothelium. After this procedure the localization of the above proteins in the SMCs was still the same and the SMC localization confirmed. Interestingly, following double staining with GFAP (a selective marker of astrocytes), we noted that the expressions of MMP-9 and TIMP-1 were not associated with glial or astrocyte end-feet in the vessel walls. This confirmed and supports that the transcriptional upregulation takes place in the vascular SMCs themselves. There was a rich network of GFAP-positive astrocytes in the cerebral cortex tissue and around the microvessels. This is in agreement with a previous study that demonstrated the presence of astrocytic end-feet surrounding the microvasculature [213].&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Figure 5. Double immunofluorescence staining for MMP-9 or TIMP-1 and SMCs actin in the MCA after MCAO. Photographs show the localization of MMP-9 and TIMP-1 (green) and of actin (red) in smooth muscle cells, and their co-localization (yellow fluorescence in the merged picture).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Cytokines and iNOS expression associated with infarct volume and neurological scores&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; It is well established that the neuroinflammatory process is complex and involves numerous pathways and molecules in the brain. However, relatively little information is available on the role of the cerebrovascular SMCs in this process following cerebral ischemia. Therefore, the next step was to investigate early changes in cytokine expression in the wall of cerebral vessels after focal ischemia. &lt;br/&gt;&lt;br&gt; Previously, Vikman and co-workers revealed, using microarray and qPCR analysis, that upregulation of cytokine genes occurs in the walls of the cerebral arteries at 24 hours after cerebral ischemia and after organ culture [8, 9]. To investigate if the upregulated genes are translated to proteins, immunohistochemistry was used to detect TNF-α, IL-6 and IL-1ß protein expression in brain vessel walls at 48 hours after MCAO. We observed significantly enhanced expression of TNF-α, IL-6 and IL-1ß proteins in the walls of MCA and brain microvessels (paper II). Notably, this enhanced expression was primarily located in the cytoplasm of the SMCs (co-localization with actin), while a weak expression was in addition seen for IL-6 and IL-1ß in the endothelial cells. Taken together with the results obtained by Vikman at 24 hours, our results support the notion that a transcriptional event is involved. &lt;br/&gt;&lt;br&gt; It is thought that cytokines such as TNF-α, IL-6 and IL-1ß are involved in the development of secondary brain damage and are associated with increased infarct size through upregulation and activation of adhesion molecules, leukocyte infiltration and MMP-9 activation [76, 96, 214].&lt;br/&gt;&lt;br&gt; At 48 hours after MCAO, we also revealed that acute cerebral ischemia followed by reperfusion in the rat is accompanied by an infarct volume of 25 ± 2% of total cerebrum and a poor neurological score (Figure 6). The results are in agreement with those of previous studies. In parallel there is elevated expression of TNF-α and IL-1ß in the cortex after both transient and permanent MCAO in rat [104, 215]. It has been reported that intracerebroventricular injection of antibodies against TNF-α and IL-1ß starting at 30 minutes before permanent MCAO or immediately after reperfusion following transient MCAO reduced infarct volume [104, 215]. Vila and co-workers have reported high levels of IL-6 and TNF-α in plasma and CSF of patients within the first 48 hours after ischemic stroke onset, which correlated with early neurological deterioration, raised body temperature, and a larger infarct volume [216]. In addition, stroke is associated with enhanced expression of some GPCRs that mediate vasoconstriction. We have recently revealed that cytokines can, at least in vitro, enhance this expression [217]. Thus, there may appear a link between the expression of cytokines and the brain damage.&lt;br/&gt;&lt;br&gt; In conjunction with an inflammatory reaction there is formation of iNOS [218]. This is another inflammatory mediator which is expressed in the brain following cerebral ischemia and its expression can be stimulated by cytokines [51]. In addition, iNOS is involved in secondary brain injury through production of COX and free radicals, which are putative mediators of BBB disruption and brain edema, leading to increased infarct volume [219, 220]. Therefore, we decided to investigate if there is upregulation of iNOS in the vessel walls at 48 hours post-ischemia. In concert with the findings for cytokines and MMP-9, we noted a marked expression of iNOS in the SMCs of both MCA and microvessels on the ischemic side compared to the contralateral side. This finding is supported by a previous study by Iadecola of iNOS mRNA and protein expression in the ischemic brain at 48 hours after MCAO [221]. &lt;br/&gt;&lt;br&gt; One important observation we made was that the upregulation of cytokines, iNOS and MMPs occurred not only in large cerebral arteries but also in associated microvessels in the affected brain region. This indicates that both large cerebral arteries and associated microvessels in the ischemic region are actively participating in inflammatory responses and production of inflammatory mediators following focal ischemic stroke. This provides the first direct evidence of an associated vascular mechanism, involving both large cerebral arteries and brain microvessels.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; MEK-ERK1/2 pathway regulating upregulat</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3ffcafbe-84b2-4cee-917a-27d1420895f6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Aida_Maddahi.pdf">https://portal.research.lu.se/files/3196447/2969084.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2613620</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Mitogen activated protein kinase</topic> <topic>iNOS</topic> <topic>Matrix metalloproteinases</topic> <topic>IL-1ß</topic> <topic>IL-6</topic> <topic>TNF-α</topic> <topic>Inflammation</topic> <topic>Subarachnoid hemorrhage</topic> <topic>Middle cerebral artery occlusion</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-16-6</identifier> <identifier type="oldLupId">2861175</identifier> <part> <detail type="volume"> <number>2012:53</number> </detail> <extent unit="pages"> <total>170</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-08-31T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>3ffcafbe-84b2-4cee-917a-27d1420895f6</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:09:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:04:02Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:09:38+02:00</recordDateApproved> </recordInfo> </mods>

In spite of political turmoil, frequent natural disasters and widespread corruption it has, in less than four decades after its birth as an independent state, gained visible success in human development - especially the education of women and girls, family planning and health, and microcredit to the poor. &lt;br/&gt;&lt;br&gt; As a Muslim country it has strong patriarchal social norms and cultural legacies that are predominantly derived from Hinduism. In general, most of the population is religious and devoted to a life of piety. On the one hand, the lives of women are affected by the prevailing patriarchy, religious practices, social and cultural norms. On the other hand, women are also influenced by the conscious interventions of the government, NGOs and microcredit institutions. In recent decades, the status of women has changed drastically from limited movement inside the four walls of the home to a dominant presence in the labour-market, small businesses, careers in media and private sectors, participation in local as well as national politics, and a greater role in household decisionmaking. &lt;br/&gt;&lt;br&gt; The country has a long tradition of Sufi orders which hold reasonably sympathetic outlooks towards women. However, in recent years, Bangladesh has been deeply influenced by Deobandi-cum-Wahhabi Islam with Salafi ideology. This ideology has been propagated through countrywide qaomi madrassahs and Jamaat-e-Islami’s devotional activities that are combined with economic, theological, and moral support from Middle Eastern societies. Since the beginning of 1990s, religious militancy, in the name of the Puriterian movement with the slogan “return to the origin”, has increased drastically. This has resulted in countrywide terrorist activities, demonstrations against development programmes by the Grameen Bank and other NGOs, misogynous activities including attacks on women and organizers involved with NGOs, and the denial of secular laws resulting in numerous attacks on public premises and holy shrines of Muslim saints. &lt;br/&gt;&lt;br&gt; This study thus provides an analytical discussion on the status of rural women in Bangladesh focusing on the legal status, religious practices, and patriarchal social norms in a new era of economic freedom created by microcredit programmes and government policies. It also analyses the conflict and debate about women and development activities between NGOs and the Islamist groups.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bangladesh är ett av världens folkrikaste muslimska länder. Sedan självständigheten har invånarna – trots politisk oro, massiva naturkatastrofer och utbredd administrativ korruption – upplevt en positiv utveckling, särskilt vad gäller kvinnors utbildning, hälsovård och familjeplanering. Denna avhandling diskuterar kvinnors levnadsförhållanden på landsbygden med fokus på rättsliga positioner, sociala och kulturella normer, religiös praxis samt konflikten mellan icke-statliga organisationer, religiösa grupper och deras allianser. &lt;br/&gt;&lt;br&gt; Det bangladeshiska samhället präglas inte bara av islam utan också av starka patriarkala sociala normer och det hinduiska kulturella arvet, men många människor är fromma och religion spelar en viktig roll i det dagliga livet. Kvinnors livssituation påverkas därför dels av det rådande patriarkatet, religiös praxis samt traditionella sociala och kulturella normer; dels av åtgärder från regeringen och organisationer som sysslar med mikrokreditfinansiering. Kvinnors roll och status i samhället har förändrats drastiskt, från begränsad rörlighet inom hemmet till en ansenlig närvaro på arbetsmarknaden; som småföretagare, inom medier och den privata sektorn, samt i lokal och nationell politik. De har också fått en stärkt roll vad gäller beslutsfattande inom det egna hushållet.&lt;br/&gt;&lt;br&gt; Landet har en lång tradition av sufism där de olika ordnarna anses ha en öppnare syn på kvinnors roll i samhället och i religionsutövning. Sedan början av 1990-talet har dock Bangladesh blivit starkt påverkat av Deobandi-wahhabitisk islam och salafi-ideologi, främst genom uppkomsten av de många religiösa skolorna s.k. qaomi madrassah och den landsomfattande organisationen Jamaat-e-Islami. Bägge dessa verksamheter stöds ekonomiskt, teologiskt och moraliskt från länder i Mellanöstern. Salafi-ideologin förespråkar en ”återgång till ursprunget” d.v.s. budskapet i Koranen och haditherna. Denna utveckling har resulterat i landsomfattande våldsdåd, demonstrationer mot Grameen Bank och andra icke-statliga organisationer, angrepp på kvinnor och arrangörer som anlitar respektive arbetar inom dessa organisationer, samt förnekande av sekulära lagar. Samtidigt har många attacker mot offentliga lokaler och muslimska helgedomar utförts.&lt;br/&gt;&lt;br&gt; Denna studie ger således en analys av situationen för kvinnor på landsbygden i Bangladesh gällande religiös praxis, lagstiftning och hotet mot patriarkala sociala normer i en ny era av ekonomisk frihet genom mikrokreditprogram och regeringens politik. Dessutom analyseras den pågående konflikten och debatten mellan de icke-statliga organisationerna och olika religiösa grupperingar angående dessa frågor.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0f588f9f-b01f-44d2-87b3-bd3d7e2019e2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Abdel.Baten.Miaji.Thesis.pdf">https://portal.research.lu.se/files/3198757/1586155.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1609017</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>History of Religions, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>NGOs</topic> <topic>Islamology</topic> <topic>Women in Bangladesh</topic> <topic>nongovernment institutions</topic> <topic>Gender</topic> <topic>Rural Bangladesh</topic> <topic>Qur&apos;an</topic> <topic>Legal status of women</topic> <topic>Islamists</topic> <topic>Bangladeshi girls</topic> <topic>Bangladesh</topic> <topic>Village women</topic> <topic>Islam</topic> <topic>Women</topic> <topic>Hadith</topic> <topic>History of Religion</topic> </subject> <subject authority="lup"> <topic>Philosophy, Ethics and Religion</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in History of Religions</title> </titleInfo> <identifier type="issn">1103-4882</identifier> <identifier type="isbn">978-91-628-8052-1</identifier> <identifier type="oldLupId">1579637</identifier> <part> <detail type="volume"> <number>26</number> </detail> <extent unit="pages"> <total>230</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-21T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>0f588f9f-b01f-44d2-87b3-bd3d7e2019e2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:09:56+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:09:56+02:00</recordDateApproved> </recordInfo> </mods>

The privileges to print catechisms and hymnbooks in Finnish now belonged again to the university of Åbo, but the Carlbohms continued to print these best-selling articles in Stockholm. According to my thesis the name of the printer is symbolic capital, which by means of symbolic and material investments, social networks and habitus(Bourdieu)by time converts the printer&apos;s name to a trade mark symbolizing the printing enterprise both materially and culturally. Frenckell&apos;s victory in the battle was twofold: he obtained both the privilege to print these profitable books and was authorized to use his own name on the title-page of the academic works from the academic printing house. Frenckell&apos;s name was occuring on title-pages of academic prints as well of texts of more popular character, and was thus contributing to the efforts for the best interests of the Enlightenment. This epoch of the Finnish Age of Enlightenment, at the same time the epoch the two first university printers Frenckell in Åbo, Johan Christopher Frenckell I,(1719-1779),and Johan Christofer Frenckell II (1757-1818),forms the background of the decades during which the name of Frenckell is making a symbolic transfer to cultural capital. The social status of the printers was rising, and they would gain, with time, cultural as well as economic capital.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d26f37bd-80f0-4668-bcf1-8b83582bdfff</url> </location> </relatedItem> <originInfo> <publisher>Avdelningen för ABM och bokhistoria, Lunds universitet</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>reading history</topic> <topic>book market</topic> <topic>the Finnish Age of Enlightenment</topic> <topic>Johan cristofer Frenckell II (1757-1818)</topic> <topic>book history</topic> <topic>Johan Christopher Frenckell I (1719-1779)</topic> <topic>university history (Åbo)</topic> <topic>academic printing house history</topic> <topic>cultivation</topic> <topic>library history</topic> </subject> <subject authority="lup"> <topic>Cultural Studies</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Bokhistoriska skrifter</title> </titleInfo> <identifier type="issn">1400-7371</identifier> <identifier type="isbn">978-91-628-7912-9</identifier> <identifier type="oldLupId">1566311</identifier> <part> <detail type="volume"> <number>5b</number> </detail> <extent unit="pages"> <total>284</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-07T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>d26f37bd-80f0-4668-bcf1-8b83582bdfff</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:10:01+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:10:01+02:00</recordDateApproved> </recordInfo> </mods>

Malfunctions of channels, as well as deregulations of their activity underlie numerous disorders and diseases commonly called channelopathies. In β-cells Ca2+ channels are central players for insulin secretion. In response to glucose, as well as other nutrients, channels mediate influx of extracellular Ca2+, which triggers insulin secretion. In spite of the fact that inadequate insulin secretion causes type 2 diabetes (T2D) and that some successful therapies for this disease target Ca2+ channels, there is still insufficient evidence to consider this disease as channelopathy. Recently, our research group demonstrated that β-cells from T2D individuals carry mutations in L-type Ca2+ channel gene, which impair expression of this channel and increase the risk for T2D. This study instigated further curiosity as to how physiological stimuli regulate the surface expression of L-type Ca2+ channels and whether this regulation is altered in T2D with consequences for cellular homeostasis, and survival. Present thesis addresses these questions.&lt;br/&gt;&lt;br&gt; The first study identified a mechanism, by which β-cells regulate surface expression of L-type Ca2+ channels in response to glucose and activation of channels. Stimulation of clonal, insulin-secreting cells caused evacuation of L-type channels from the plasma membrane to the cytosol. This effect was reversible after cessation of the stimulation and was mediated by eIF3e, the novel regulatory protein of Ca2+ channels. Ablation of eIF3e abolished channel internalization, thereby rendered cells prone to Ca2+ overload.&lt;br/&gt;&lt;br&gt; The second study showed that in β-cells from T2D human donors the number of L-type channels at the plasma membrane is elevated and that internalization mechanism is not functional. These two abnormalities cause cells susceptible to toxicity of glucose due to Ca2+ overload mediated by L-type Ca2+ channels entrapped in the plasma membrane.&lt;br/&gt;&lt;br&gt; The third study delineated mechanism, through which Ca2+ overload contributes to the loss of β-cell mass observed in T2D in the presence of elevated levels of glucose and free fatty acids, the characteristic milieu for this disease. Overly active L-type Ca2+ channels activated Nur77 and Nor-1 proteins, which inhibited autophagy, the crucial process rescuing cells from cytotoxic stresses exerted by glucose and free fatty acids.&lt;br/&gt;&lt;br&gt; Taken together, this thesis shows that L-type Ca2+ channels determine vitality of β-cells and that deregulation of expression of these channels occurs in T2D contributing to progression of the disease.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2f4c8fda-8cb6-4aba-b275-0a0fde77f7c5</url> </location> </relatedItem> <originInfo> <publisher>Islet patophysiology, Clinical Sciences, Malmö</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>autophagy</topic> <topic>apoptosis</topic> <topic>calcium channels</topic> <topic>Type 2 Diabetes</topic> </subject> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-176-7</identifier> <identifier type="oldLupId">7852270</identifier> <part> <detail type="volume"> <number>2015:97</number> </detail> <extent unit="pages"> <total>54</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-10-01T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>2f4c8fda-8cb6-4aba-b275-0a0fde77f7c5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:10:12+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:10:12+02:00</recordDateApproved> </recordInfo> </mods>

The effect of this intervention was evaluated on health-related quality of life. (Paper II) GPs’ and nurses’ opinions towards the previous pharmacotherapeutic intervention, in Paper I, were evaluated using a questionnaire. (Paper III) Medication errors during the transfer between primary care and hospital were investigated for patient providing care by the community, by collecting and reviewing all medication notes used for the information transfer. (Paper IV) Clinical pharmacists interviewed patients admitted to the hospital using the developed Structured Medication Questionnaire, to identify medication errors and assess patients’ compliance to and beliefs about medicines. (Paper V) Systematic medication reviews and medication care plans were conducted on intervention inpatients, by a multidisciplinary team, to reduce the number of unidentified drug-related problems during the hospital stay, which were identified and evaluated retrospectively. The physicians’ and nurses’ opinions towards this working model were evaluated using a questionnaire. &lt;br/&gt;&lt;br&gt; Result: (Paper I) Many drug-related problems were identified among the nursing home patients, but no improvement in health-related quality of life. (Paper II) Both GPs and nurses were positive towards further cooperation regarding pharmacotherapeutic interventions. (Paper III) On average two medication errors occurred each time a patient was transferred between primary and secondary care. (Paper IV) A majority of the patients (62%, CI 45-77%) had at least one medication error. Using this questionnaire, poor compliance and negative beliefs were also identified. (Paper V) Inpatients in the intervention group benefited from a reduction of unidentified drug-related problems. In general physicians and nurses were very positive towards this working model. &lt;br/&gt;&lt;br&gt; Conclusion: The research comprising this thesis has demonstrated a need for attention towards drug treatment and drug-related problems in the elderly. The Structured Medication Questionnaire and structured medication reviews may be used as tools to identify drug-related problems. Once identified the drug-related problems have the potential to be prevented or resolved, thereby optimising drug therapy.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8b47eb29-5cb9-461e-bef6-c6e46a36f1df</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappan.pdf">https://portal.research.lu.se/files/3200502/1267076.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">164248</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Clinical Chemistry and Pharmacology, Dept of Laboratory Medicine</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>medication histories</topic> <topic>medication reviews</topic> <topic>drug-related problems</topic> <topic>elderly</topic> <topic>medication errors</topic> <topic>pharmacists</topic> <topic>drug therapy</topic> </subject> <subject authority="lup"> <topic>Pharmacology and Toxicology</topic> <topic>Medicinal Chemistry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-63-7</identifier> <identifier type="oldLupId">1267069</identifier> <part> <detail type="volume"> <number>2008:110</number> </detail> <extent unit="pages"> <total>103</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-05T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>8b47eb29-5cb9-461e-bef6-c6e46a36f1df</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:10:14+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:10:14+02:00</recordDateApproved> </recordInfo> </mods>

The general objective of the present investigation was to validate these results in a Swedish routine emergency setting were the prevalence of the disease is high and were the clinical probability assessment was handled by many junior physicians. Furthermore, our aims were to evaluate our D-dimer method and to make comparisons with other D-dimer methods as with a new marker of coagulation, the APC-PCI complex. In addition, a cost effectiveness analysis was made of this diagnostic strategy.&lt;br/&gt;&lt;br&gt; Material and methods: 357 outpatients with clinical suspicion of DVT were included in the clinical management study. The diagnostic workup included estimation of pre-test probability, D-dimer determination, objective imaging as well as 3 month clinical follow up of negative patients (Paper I). 350 plasma samples from the management study was used for comparison between two well established D-dimer methods and the APC-PCI complex (Paper II) and 311 plasma samples for the evaluation of two new D-dimer methods (Paper III). Direct and indirect costs were calculated for the tested diagnostic strategy and for two hypothetical strategies. A decision analysis was performed (Paper IV).&lt;br/&gt;&lt;br&gt; Results and conclusions: One out of 110 patients categorized as having a low clinical probability in combination with a negative D-dimer test was diagnosed with DVT during follow up. About 30% of the patients do not need further investigation for DVT. The APC-PCI complex perform inferior to the D-dimer methods for the exclusion of DVT but slightly superior when indicating its presence. &lt;br/&gt;&lt;br&gt; The AxSYM® and Innovance™ D-dimer assays perform well and in good agreement with the two well established assays with NPV´s of &amp;gt; 98% in the low clinical probability estimate (CP). Objective imaging in all patients was the least cost effective (€581) strategy, D-dimer screening of all patients before CP (€421) and CP in combination with D-Dimer testing only in patients with low CP (€406). Conclusion: the investigated diagnostic strategy is safe, result in more convenient and cost-effective care for patients.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Övergripande syfte&lt;br/&gt;&lt;br&gt; Syftet med avhandlingen var att utvärdera hur en förenklad metod för diagnostisering av blodproppar i benets djupa ådror (djup ventrombos (DVT)) fungerar i svensk rutinsjukvård. Den förenklade metoden innebär användning av en strukturerad klinisk sannolikhetsbedömning tillsammans med ett blodprov (D-dimer test). Vi jämförde också vår D-dimermetod med andra D-dimermetoder samt utvärderade en ny blodproppsmarkör (APC-PCI komplexet) som vi hoppades ha förutsättningar för att bli en bättre markör för blodpropp än D-dimermetoden. Vidare ville vi se om den nya diagnostiska metoden är kostnadseffektiv jämfört med 1) den gamla metoden och 2) en felaktig användning av den nya metoden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Allmän bakgrund&lt;br/&gt;&lt;br&gt; Andelen människor som årligen insjuknar i DVT ca 100/100 000 innevånare. Endast 10-25% av patienter som söker på grund av misstänkt DVT har sjukdomen. Antalet insjuknade per år är lika för män och kvinnor. Graviditet är en riskfaktor för DVT och den kliniska bedömningen är svår då bensvullnad och vidgade blodådror kan vara ett normaltillstånd framför allt i sen graviditet. De vanligaste orsakerna till att man börjar misstänka DVT är bensmärta och/eller svullnad. Eftersom symtom och undersökningsfynd är väldigt ospecifika har man historiskt låtit alla patienter med misstänkt ventrombos genomgå kontrast eller ultraljudsundersökning av de djupa blodådrorna. Ett sådant förfarande har varit kostsamt, tidskrävande och inneburit vissa medicinska risker för patienterna ( kontrastmedels allergi, njurskada mm). Flera studier har sedan slutet av 90-talet påvisat att det går att förenkla diagnostiken genom att införa en metod som bygger på att man på ett strukturerat sätt försöker skatta sannolikheten för DVT (poänggraderat diagnosstöd) och därefter använda sig av olika enkla icke-invasiva test. Kombinationen av en låg klinisk sannolikhet och ett normalt blodprovsresultat avseende nedbrytningsprodukter av en blodpropp (D-dimer), har visats sig kunna utesluta DVT hos en betydande del av patienterna. Invändningarna mot att införa denna nya diagnostiska modell har varit:&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; 1) Andelen patienter med faktisk blodpropp kan vara högre på våra akutmottagningar än vad som var fallet i de tidigare studierna, detta skulle öka risken för att felaktigt utesluta DVT (missa sjukdomen).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; 2) Våra D-dimer metoder skulle kunna skilja sig åt avseende känslighet och specificitet jämfört med dem som använts i de tidigare studierna och därigenom också öka risken för att missa DVT.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; 3) Det poänggraderade diagnosstödet innehåller två punkter som inte är helt objektiva;&lt;br/&gt;&lt;br&gt; i) ömhet över djupa kärlsträngen och&lt;br/&gt;&lt;br&gt; ii) annan diagnos minst lika trolig som DVT. &lt;br/&gt;&lt;br&gt; Poänggraderingen kan därför t.ex. påverkas av om doktorn har en lång klinisk erfarenhet eller inte. Detta kan vara problematiskt då svenska läkare arbetar förhållandevis självständigt redan tidigt i karriären.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har under åren 2003-2006 inkluderat 357 patienter med misstänkt DVT, i en multicenterstudie. Alla patienter har poänggraderats med hjälp av en standardiserad klinisk sannolikhetsbedömning. D-dimer är analyserat lokalt (respektive sjukhus) på de patienter som poänggraderats till en låg klinisk sannolikhet för DVT. Patienter med normal D-dimer nivå har inte erhållit någon blodförtunnande behandling eller genomgått ytterligare diagnostik avseende DVT. Dessa patienter och har sedan följts upp avseende blodproppsinsjuknande under 3 månader. Övriga patienter (förhöjd D-dimer nivå eller hög klinisk sannolikhet för DVT) har genomgått sedvanlig objektiv diagnostik med kontraströntgen av blodådrorna eller en ultraljudsundersökning. Utöver lokalt analyserat D-dimer har vi också analyserat och jämfört flera andra D-dimer metoders diagnostiska prestanda och APC-PCI komplexet i relation till kliniskt utfall.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattning av avhandlingens studier&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete I: I detta arbete kunde vi visa att klinisk sannolikhetsbedömning enligt Wells och medarbetare, tillsammans med vår D-dimer metod fungerade i rutinsjukvård. Av de 110 patienter som av läkaren bedömdes ha en låg klinisk sannolikhet och där D-dimernivån var normal kom endast 1 patient tillbaka under uppföljningen med blodpropp i benet. Denna andel missade patienter (falskt negativa) är densamma som referensmetoderna (kontraströntgen och ultraljud) har. En dryg tredjedel av patienterna kan slippa kontraströntgen eller ultraljudsundersökning av de djupa blodådrorna. Vi kunde även visa att mätsäkerheten av D-dimer metoden var densamma oavsett om proverna analyseras på ett koagulationslaboratorium eller lokalt på respektive sjukhus.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete II: Baseras på ovan material och syftar till att utvärdera APC-PCI komplexets prestanda i relation till kliniskt utfall och att jämföra resultatet med två etablerade D-dimer metoder. Slutsatsen i detta arbete är att APC-PCI komplexet, jämfört med D-dimer metoderna, har en något sämre förmåga att hjälpa till med att utesluta DVT men en möjlig fördel när det gäller att hjälpa till med att påvisa förekomst av DVT.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete III: Två, på marknaden, nya D-dimer metoder testas och jämförs med två väletablerade metoder. Slutsatsen i detta arbete är ett de nya D-dimer metoderna är jämförbara med de etablerade och kan användas tillsammans med klinisk sannolikhetsbedömning för att utesluta DVT. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete IV: Hälsoekonomisk kostnad-effektivitets analys&lt;br/&gt;&lt;br&gt; Två jämförelser vidtogs: 1) Den nya diagnostiska modellen jämförs med den gamla (alla patienter genomgår bilddiagnostik) och 2) en ”felaktigt” använd ny modell (alla patienter testas med D-dimer innan läkarbedömning). Utfallet av denna analys visar att det blir billigare att använda den nya modellen jämfört med den gamla, men också att en felaktigt använd ny modell innebär att de potentiella besparingarna minskar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Diskussion och slutsatser&lt;br/&gt;&lt;br&gt; Vi kan genom att använda den nya diagnostiska modellen, med bibehållen säkerhet och till en lägre kostnad, utesluta behandlingskrävande DVT hos nästan 1/3 av alla patienter som söker på våra akutmottagningar. Studierna visar också att valet av testmetod och vald beslutsgräns (tex mängd D-dimer i blodet) för sjuk/inte sjuk är viktig. Hög diagnostisk känslighet innebär att man fångar de flesta som är sjuka men också att många friska kommer att falla ut som sjuka (falskt positiva). De falskt positiva patienterna kommer att behöva genomgå kontraströntgen eller ultraljudsundersökning i onödan. En mindre känslig testmetod riskerar att missa några sjuka patienter (falskt negativ) men innebär också att färre friska blir felaktigt klassade som sjuka. Val av testmetod och beslutsgräns bör därför helst prövas i sin egen miljö i prospektiva utfallsstudier likt vår. Arbete IV exemplifierar detta genom att hypotetiskt testa vad utfallet skulle bli om man använder modellen felaktigt. Eftersom D-dimermetoderna generellt sett är högkänsliga med låg specificitet innebär detta att om man på ett oselekterat patientmaterial analyserar D-dimer kommer många av de friska (Ej DVT) att visa sig ha en förhöjd D-dimernivå. Trots detta är det mindre än hälften som faktiskt har en DVT. APC-PCI komplexets roll i diagnostiken av DVT är fortfarande inte helt klar och ytterligare studier behövs på detta område.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e859d27f-c4a4-42bb-81a8-6247f9c4b5cb</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Elf.pdf">https://portal.research.lu.se/files/3204129/1607531.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4630169</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Venous thrombosis</topic> <topic>APC-PCI complex.</topic> <topic>D-Dimer</topic> <topic>Clinical probability</topic> <topic>Diagnosis</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-33-7</identifier> <identifier type="oldLupId">1578719</identifier> <part> <detail type="volume"> <number>2010:19</number> </detail> <extent unit="pages"> <total>112</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-04-10T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>e859d27f-c4a4-42bb-81a8-6247f9c4b5cb</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:10:21+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:10:21+02:00</recordDateApproved> </recordInfo> </mods>

Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. However, except in a metaphorical sense, the cerebellum, which consists of a set of interconnected nerve cells, cannot contain “internal models” or “have expectations”. The aim of this thesis is to untangle these metaphors by translating them back into neurophysiological cause and effect relationships. This task is approached from within the paradigm of classical conditioning, in which a subject, through repeated presentations of a conditional stimulus, followed by an unconditional stimulus, acquires a conditioned response. Importantly, the conditioned response is timed so that it anticipates the unconditioned response. Available neurophysiological evidence suggests that Purkinje cells, in the cerebellar cortex, generate the conditioned response. In addition, Purkinje cells provide negative feedback to the IO, which is a relay for the unconditional stimulus, via the nucleo-olivary pathway. Purkinje cells can therefore regulate the intensity of the signal derived from the unconditional stimulus, which, in turn, decides subsequent plasticity. Hence, as learning progresses, the IO signal will become weaker and weaker due to increasing negative feedback from Purkinje cells. Thus, in an important sense, learning induced changes in Purkinje cell activity constitute an “expectation” or “anticipation” of a future event (the unconditional stimulus), and, consistent with theoretical models, future learning depends on the accuracy of this expectation. Paper 1 in this thesis show that learned changes in Purkinje cells influences subsequent IO activity. The second paper show that, depending on the number of pulses it contains, the signal from the IO to the Purkinje cells can either cause acquisition or extinction. In the third paper we present evidence that can potentially help explain overexpectation, a behavioral phenomenon, which have for long been elusive. Collectively these papers advance our understanding of the feedback mechanisms that govern cerebellar learning and it proposes a potential solution to some long standing behavioral conundrums.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/bf0be5d6-e9fe-4816-a28e-f7cff7d065ae</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis.pdf">https://portal.research.lu.se/files/3204185/4437426.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">956776</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Associative Learning</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Motor learning</topic> <topic>Rescorla-Wagner</topic> <topic>Anticipation</topic> <topic>In vivo Electrophysiology</topic> <topic>Purkinje cells</topic> <topic>Nucleo-Olivary inhibition</topic> <topic>Inferior Olive</topic> <topic>Classical Conditioning</topic> <topic>Eyeblink Conditioning</topic> <topic>Feedback</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-96-0</identifier> <identifier type="oldLupId">4437425</identifier> <part> <detail type="volume"> <number>2014:69</number> </detail> <extent unit="pages"> <total>46</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-07T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>bf0be5d6-e9fe-4816-a28e-f7cff7d065ae</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:10:21+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:10:21+02:00</recordDateApproved> </recordInfo> </mods>

Even though alcohol effects on balance and eye movement have been studied before we know less about the dose and time dependent effects and how each supportive sense to balance contributes during acute alcohol intoxication. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The purpose was to investigate parallel effects of acute alcohol intoxication on balance (postural control), balance efficiency (adaptation) and its supporting senses. We included 25 healthy subjects on three different test occasions during acute alcohol intoxication of 0.06% and 0.1% blood alcohol concentration (BAC) and sober, ensured using a real time breath analyzer.&lt;br/&gt;&lt;br&gt; Balance was evaluated with a balance force plate and a 3D-system for individual body segment detection. Spatial orientation and eye movements were measured. Foot sensation was measured when sober and the subjective feeling of intoxication was continuously followed.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Instability was considerably higher at 0.1% BAC compared to 0.06% BAC and was more obvious in the medio-lateral (side to side) direction compared to the anterior-posterior (front and back). When standing balance is perturbed by vibration of the calf muscles, body movement increases. Repetition of these perturbations drives balance learning (adaptation) in sober subjects and the result is a reduction of body movement. When intoxicated however, normal adaptation is reduced or abolished.&lt;br/&gt;&lt;br&gt; Whilst visual feedback is important for maintaining stability, it didn’t fully compensate for being intoxicated and contradictorily decreased medio-lateral stability. This could partly be explained by the impaired eye movements by intoxication. Additionally, being intoxicated increased visual dependence, i.e., the use of visual senses for positioning ourselves within the environment. Together, it illustrates that being intoxicated causes an over-reliance on visual senses which aren’t always helpful.&lt;br/&gt;&lt;br&gt; When visual senses are absent, intoxicated subjects will rely upon foot mechanoreceptive sensation for standing balance, and change their balancing strategy by pivoting more prominently forwards and backwards around the knee level. One’s own perception of drunkenness matches slow eye movements as well as upper body movement.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In summary, alcohol intoxication at levels common in society, has a widespread disturbing effect on the components of the human balance system, from each sensory system to the Central Nervous System’s integrative and cognitive processing, and also effects adaptive ability, the summation of which produces a complex attack on postural and oculomotor behaviors.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/bfa2572d-c76d-4cd2-a336-9cec753567f1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="fredrik_modig_avhandling.pdf">https://portal.research.lu.se/files/3206348/3460149.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1252589</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Otorhinolaryngology (Lund), Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Oto-rhino-laryngology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-93-7</identifier> <identifier type="oldLupId">3460125</identifier> <part> <detail type="volume"> <number>2013:24</number> </detail> <extent unit="pages"> <total>99</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-03-08T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>bfa2572d-c76d-4cd2-a336-9cec753567f1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:10:37+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:10:37+02:00</recordDateApproved> </recordInfo> </mods>

Within the Jordtorp-area,&lt;br/&gt;&lt;br&gt; a mosaic agricultural landscape on the island of Öland (Sweden), historical land-use changes and the development of semi-natural grasslands was characterized, over a time-period of almost 300 years, using historical maps, aerial photographs and a high-resolution imagery. The study also examines the relative importance of management conditions and habitat history (in terms of continuity, previous land-use), on present-day vascular plant species diversity within the semi-natural grasslands.&lt;br/&gt;&lt;br&gt; Present-day grasslands represent 18% of the grassland area found at the beginning of the 18th century. The most dramatic loss of grassland habitat took place between late 19th century and the beginning of the 20th century, resulting in a progressive grassland fragmentation during the 20th&lt;br/&gt;&lt;br&gt; century.&lt;br/&gt;&lt;br&gt; Results from the Jordtorp-area showed that present levels of small-scale (&amp;lt;1m2) species diversity reflects both present grassland connectivity and grassland connectivity of past landscapes – suggesting that the losses and fragmentation of the semi-natural grasslands within the landscape has had an&lt;br/&gt;&lt;br&gt; effect on the plant species communities. However, as some part of the diversity was associated with the grassland connectivity of past landscapes, further diversity declines are to be expected within the&lt;br/&gt;&lt;br&gt; grasslands.&lt;br/&gt;&lt;br&gt; Present levels of plant species diversity are not only a reflection of the present and past grassland structure, the variation in diversity also reflects the characteristics of the surrounding landscape and land-use legacies related to the historical villages, suggesting that focusing solely on habitat structure provides a limited perspective on the driving forces behind the loss of diversity.&lt;br/&gt;&lt;br&gt; Habitat continuity and previous land-use of present grassland fragments had a significant influence on present-day species diversity. The total richness of both generalist and specialist species, on large-scale, increased with habitat age, while the richness of species on small-scale showed no relationship with habitat age. However, the proportion of specialist and generalist species on smallscales was highly dependent on previous land-use.&lt;br/&gt;&lt;br&gt; Both present management intensity and the long-term continuity of management were significantly associated with present-day species diversity. A unimodal association between species diversity and distance from nearest settlement suggest that diversity is promoted by a history of&lt;br/&gt;&lt;br&gt; moderate grazing intensity.&lt;br/&gt;&lt;br&gt; An overall conclusion from the Jordtorp-area is that both habitat quality (environment and management) and habitat availability (connectivity) have a significant impact on species diversity. The results from the thesis emphasize the importance of a landscape perspective in both time and space – embracing the spatial structure of the grassland habitat, the wider landscape as well as the land use history of the area.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/be99864e-011e-4510-940a-00db7e511cb6</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>aerial photographs</topic> <topic>Land-use history</topic> <topic>cadastral maps</topic> <topic>habitat continuity</topic> <topic>fragmentation</topic> <topic>landscape context</topic> <topic>habitat connectivity</topic> </subject> <subject authority="lup"> <topic>Physical Geography</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Meddelanden från Lunds universitets geografiska institution.

The study confirms the superior survival after intensive therapy also in a population-based setting. Intensive as opposed to non-intensive treatment was the main prognostic factor for survival, while age was not associated with an inferior outcome among intensively treated patients.&lt;br/&gt;&lt;br&gt; The other three studies focus on outcome in peripheral T-cell lymphomas (PTCL). The second study investigates outcome according to treatment and standard clinical factors at diagnosis. Male gender was found to be associated with inferior survival. Intensification of first-line treatment with up-front autologous stem cell transplantation (auto SCT) consolidation was found to be associated with a favourable outcome in patients younger than 70 years. Relapsing patients had a dismal outcome, with a median post relapse survival of 6 months.&lt;br/&gt;&lt;br&gt; Study number three focused on the occurance of central nervous system (CNS) relapse in PTCL. In all, 28 patients (4.5%) experienced CNS relapse, most commonly with leptomeningeal involvement. Extensive extranodal involvement, skin or gastrointestinal involvement was associated with a higher risk for secondary CNS spread. At relapse patients had a very poor survival, irrespective of CNS involvement or not, with no survival difference between the groups.&lt;br/&gt;&lt;br&gt; The last study investigates the impact of comorbidity in PTCL. Using the Charlson Comorbidity Index (CCI), presence of concomittant disease was found to be independently associated with inferior survival. CCI was the only factor at diagnosis that showed an association with survival after first-line auto SCT. The association with favourable outcome in patients treated with auto SCT found in the second study, was still significant when adjusting for CCI. In patients ≥75 years, a similar survival in patients treated with curative and low-intensity chemotherapy was found. This was not changed when adjusting for the CCI.&lt;br/&gt;&lt;br&gt; In summary, the studies included in this thesis provides information on risk factors and population-based outcomes in T-cell lymphomas. Associations between treatment intensification and better outcome suggests a beneficial effect of these strategies in younger patients. The thesis also provides information on previously poorly documented disease, and patient-related, factors in PTCL, and will possibly serve as comparative data for future population-based studies.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/636bf408-6b0c-4bba-87e5-62fdb9264de8</url> </location> </relatedItem> <originInfo> <publisher>Lund University, Department of Clinical Siences, Lund, Oncology and Pathology</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>T-cell Lymphoblastic Lymphoma</topic> <topic>peripheral T-cell lymphoma</topic> <topic>prognostic factors</topic> <topic>autologous stem cell transplantation</topic> <topic>central nervous system relapse</topic> <topic>comorbidity</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-254-2</identifier> <identifier type="oldLupId">8728460</identifier> <part> <detail type="volume"> <number>2016:28</number> </detail> <extent unit="pages"> <total>95</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-03-18T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>636bf408-6b0c-4bba-87e5-62fdb9264de8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:10:49+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:10:49+02:00</recordDateApproved> </recordInfo> </mods>

Danish physiotherapy in a private context is practiced, administered and managed within a neoliberal ideology which generates challenges for both physiotherapists and their patients. This thesis aims to explore how physiotherapy in a Danish private context socially and ethically is practiced from the perspective of physiotherapists. &lt;br/&gt;&lt;br&gt; The thesis, which consists of four parts, is based on the same empirical material consisting of interviews with twenty-one physiotherapists and observation notes on the physical environments. The specific research aims in the studies have successively been developed through different epistemological approaches and analysis strategies. &lt;br/&gt;&lt;br&gt; The main findings show that physiotherapists in Danish private practice have a general interest in ethics which primarily is based on personal common sense arguments and intuitive feelings of ethics. The physiotherapists’ practices are ethically grounded which are shown in many situations. Their consciousness on ethical issues is discursively constructed in the first sessions as these sessions arouse both ethical and economic considerations to keep the client. Further ethical issues arise when the physiotherapists’ clientele are regarded as being at risk: in the meetings with the so-called ‘difficult’ patients as these situations do not just flow, they require ethical reflections and pedagogical strategies in order to keep them in the business. Beneficence is seen as the core value and as having importance in different relationships: towards the patient, the physiotherapists themselves and their businesses. To secure beneficence a paternalistic approach emerges towards the patient, where disciplining the patient into their ‘regimes of truth’ becomes a crucial element of practice in order to exploit the politically defined frames for optimising profit, showing how being beneficent seem to be led by structures of the neoliberal ideology which work behind the backs of the physiotherapists. Physiotherapy private practice in Denmark seems to reproduce the Western medical logic and practices whereby the physiotherapists unconsciously oppose their own political intentions to be an autonomous profession. Thus, physiotherapy in private practice inscribes itself as a ’wanna-be’ profession. The thesis has several limitations as it built solely on Danish physiotherapists’ articulations of their practices, their understandings of these and the researcher’s observation notes. This means that choosing a specific context for the thesis the findings can only be transferred to similar contexts and neither to other private or public physiotherapeutic contexts in Denmark nor to other Western countries.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Danish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Fysioterapi er en social og etisk praksis som udfolder sig under specifikke historiske, politiske, socialkulturelle og økonomiske forhold. Dansk fysioterapi i en privat kontekst er praktiseret, administreret og håndteret indenfor en neoliberal ideologi, der genererer udfordringer for både fysioterapeuter og borgere: Det forventes implicit at begge parter understøtter den neoliberale ideologi, da fysioterapeuter i privat praksis har viden og færdigheder, som de tilbyder for penge og konverterer til behandling indenfor de givne rammer og forhold, hvilket deres patienter accepterer og støtter op omkring.&lt;br/&gt;&lt;br&gt; Denne disputats har som formål at undersøge, hvordan fysioterapi i en dansk privat kontekst socialt og etisk er praktiseret, set fra fysioterapeuternes perspektiv.&lt;br/&gt;&lt;br&gt; Denne disputats, som udgøres af fire dele, er baseret på det samme empiriske materiale, der består af interviews med 21 fysioterapeuter og af forskerens observationer af de fysiske omgivelser. De specifikke forskningsspørgsmål er successivt blevet udviklet gennem forskellige espistemologiske tilgange: fænomenologisk hermeneutik, hermeneutik, social konstruktivisme og strukturel tilgang og gennem tre forskellige analyse strategier: Malterud’s ‘systematiske tekst kondensering’, Ricoeur’s ‘textual interpretation of distanciation’ og en social konstruktivistisk analyse foretaget gennem Foucault’s begreber om disciplin, selv-disciplin, modstand og magt er anvendt.&lt;br/&gt;&lt;br&gt; Hovedresultaterne viser, at fysioterapeuter i dansk privat praksis har en overordnet interesse i etik, som primært baserer sig på personlige ’sund fornuft’ argumenter og intuitive følelser om etik. Fysioterapeuternes praksisser er etisk funderet, hvilket viser sig i mange situationer. Fysioterapeuternes bevidsthed om etiske problemer er diskursivt konstrueret i det første møde i privat praksis, da mødet giver anledning til både etiske og økonomiske overvejelser for at fastholde klienten i klinikken. Fysioterapeuternes bevidsthed om etiske problemer vækkes også, når fysioterapeuternes klientel vurderes til at være de såkaldte ’besværlige’ patienter, da den fysioterapeutiske proces ikke bare glider gnidningsløst, men kræver etiske refleksioner og pædagogiske strategier for at fastholde patienterne og derved indtægten i klinikken. Godgørenhed ses som kerneværdien i fysioterapeutisk privat praksis og viser sig vigtig i forskellige sammenhænge: I forhold til patienten, fysioterapeuterne selv og deres forretning. For at sikre godgørenhed viser der sig en paternalistisk tilgang til patienterne. Patienterne disciplineres ind i fysioterapeuternes ’sandhedssystemer’, med det forhold at kunne optimere indtægten på patienten indenfor de politisk definerede rammer, hvilket overordnet understøtter den neoliberale ideologi og relaterer til en nytteetisk forståelse. Fysioterapi i dansk privat praksis viser sig at reproducere vestlige medicinske logikker og praktikker, hvorved fysioterapeuterne ubevidst modsætter sig deres egne politiske intentioner om at være en selvstændig profession. Herved indskriver fysioterapi i privat praksis sig selv som værende en ’wanna-be’ profession. Fysioterapeuternes opfattelse af deres etiske forpligtelser om at respektere patientens autonomi og være godgørende, synes at blive ført af neoliberale ideologiske strukturer, der arbejder bag om ryggen på fysioterapeuterne.&lt;br/&gt;&lt;br&gt; Denne disputats har flere begrænsninger, da den kun bygger på danske fysioterapeuters artikulationer om deres praksisser, forståelser af disse og forskerens observationer. Det betyder, at analyserne kun adresserer, hvordan fysioterapeuter på et givet tidspunkt artikulerer deres praksisser og ikke problemstillinger i forhold til funktionen af kliniske praksis indenfor praktisk realitet. Det at vælge en specifik kontekst betyder endvidere, at resultaterne kun kan overføres til sammenlignelige kontekster og ikke til andre private eller offentlige danske fysioterapeutiske kontekster eller til andre vestlige lande.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f3906a18-cedb-4d9a-adf7-1109ffc25c07</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Doktorafhandling.FINAL.pdf">https://portal.research.lu.se/files/3208114/4864783.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">880365</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Physiotherapy</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Foucault</topic> <topic>practice</topic> <topic>ethical issues</topic> <topic>professional ethics</topic> <topic>Physiotherapy</topic> </subject> <subject authority="lup"> <topic>Physiotherapy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-67-0</identifier> <identifier type="oldLupId">4864778</identifier> <part> <detail type="volume"> <number>2014:42</number> </detail> <extent unit="pages"> <total>72</total> </extent> </part> </relatedItem> <note type="teachingLearningHe">yes</note> <dateOther encoding="w3cdtf" type="defenseDate">2014-04-24T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f3906a18-cedb-4d9a-adf7-1109ffc25c07</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:10:59+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:10:59+02:00</recordDateApproved> </recordInfo> </mods>

However, these advances in treatment and survival has come at a price, and many survivors face significant treatment-induced sequelae, most of which only become clinically apparent many years after the child has been cured. Previous studies have highlighted the need for better characterization of these late complications and their risk factors, in order to improve the basis for individual patient counselling and optimal long-term follow-up care. The main objective of the studies presented in this thesis was to investigate some of the diseases that contribute to long-term morbidity in childhood cancer survivors, as well as the late socioeconomic effects after treatment for acute lymphoblastic leukaemia (ALL) in childhood.&lt;br/&gt;&lt;br&gt; All the studies presented in this thesis are population-based, retrospective cohort studies. Studies I and II are register-based studies of late socioeconomic effects and hospital-related morbidity, respectively, among 213 five-year survivors of ALL in the southern region of Sweden, compared to a population comparison cohort. Studies III–V included 33,160 one-year survivors of childhood cancer diagnosed between the start of cancer registration in the 1940s and 1950s up to and including 2008, identified in the national cancer registries of Denmark, Finland, Iceland, Norway and Sweden, and 212,892 comparison subjects, selected from national population registers. The study subjects in Studies III–V were linked to the national hospital registers and standardized hospitalization rate ratios and absolute excess risks of specific diseases were calculated.&lt;br/&gt;&lt;br&gt; ALL survivors were married, had children, attained a high level of education and were employed to a lesser extent than the comparison subjects. Young age at diagnosis and cranial radiotherapy were risk factors for these negative late socioeconomic effects. Increased morbidity among ALL survivors, measured in terms of health care utilization, was primarily confined to those treated with cranial irradiation. Nordic childhood cancer survivors exhibited an increased risk of diabetes mellitus, which persisted throughout life. In addition, survivors were found to have a substantially increased risk of other endocrine disorders. The diagnoses of pituitary hypofunction, hypothyroidism and dysfunction of the gonads were the most frequent endocrine disorders found among the survivors. Childhood cancer survivors also showed an increased risk of various autoimmune diseases; increased risk ratios were seen in survivors of leukaemia, Hodgkin’s lymphoma, renal tumours and central nervous system neoplasms. The findings of these studies underscore the need for preventive interventions and prolonged follow-up of childhood cancer survivors.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/597cf8f2-9732-446b-885c-ff2152c28baf</url> </location> </relatedItem> <originInfo> <publisher>Paediatrics, Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Childhood cancer survivors</topic> <topic>late complications</topic> <topic>morbidity</topic> <topic>late socioeconomic effects</topic> </subject> <subject authority="lup"> <topic>Pediatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-122-4</identifier> <identifier type="oldLupId">5276436</identifier> <part> <detail type="volume"> <number>2015:43</number> </detail> <extent unit="pages"> <total>97</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-13T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>597cf8f2-9732-446b-885c-ff2152c28baf</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:08+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:08+02:00</recordDateApproved> </recordInfo> </mods>

In this thesis the crosstalk between inflammation and coagulation in acute pancreatitis (AP) has been investigated.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The results from the first paper, where active site inactivated FVII (FVIIai) is given as pre-treatment in a rat model of severe AP, show a decreased inflammatory response in the FVIIai pre-treated animals.&lt;br/&gt;&lt;br&gt; In the second paper the activation of nuclear factor kappa B (NFκB) is studied in the rat model of severe AP. NFκB is a pivotal transcription factor, involved in the regulation of expression of multiple inflammatory mediators. The results show a decreased activation of NFκB in remote organs in FVIIai pre-treated rats with severe AP.&lt;br/&gt;&lt;br&gt; In the third paper the effect of FVIIai administered after the induction of severe AP in the rat model is studied. The results show some anti-inflammatory effects though less evident than in the pre-treatment study.&lt;br/&gt;&lt;br&gt; In the fourth paper the incidence, management and outcome of major haemorrhagic complications in AP is studied in a retrospective study. 1356 patients were included. Severe haemorrhagic complications turned out to be very rare. Only 14 patients with severe bleeding were identified. Despite the rareness of this condition, it is a clinical challenge to manage these patients, as severe bleeding complications are associated with a very high mortality.&lt;br/&gt;&lt;br&gt; In the fifth paper plasma levels of TF are studied in 49 patients with predicted severe AP. TF at admission was higher in the group of patients that actually developed severe AP, compared to those with a mild form of the disease. The results may indicate a role of tissue factor in the development of severe disease.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We conclude that &lt;br/&gt;&lt;br&gt; - FVIIai exerts powerful anti-inflammatory effects in experimental severe AP, at least in part by reducing activation of NFκB,&lt;br/&gt;&lt;br&gt; - Severe haemorrhagic complications in AP are rare, but associated with a high risk of mortality.&lt;br/&gt;&lt;br&gt; - Levels of TF rise early in the course of AP and higher levels of TF early in the course of the disease may be associated with development of severe AP.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Akut pankreatit (AP) är en inflammation i bukspottskörteln, som oftast utlöses av gallstenssjukdom eller alkoholintag. Varför man får akut pankreatit vet man inte och inte heller varför de flesta patienter återhämtar sig på ett par dagar, medan ca 20 procent drabbas av en betydligt svårare form av sjukdomen. Vid svår AP ses en kraftig inflammatorisk reaktion i hela kroppen, där andra organ såsom lungor, njurar och lever kan drabbas och i värsta fall sluta fungera. Dödligheten i den svåra formen av AP är hög och likaså risken för resttillstånd, t ex i form av diabetes eller brist på matspjälkningsenzymer.&lt;br/&gt;&lt;br&gt; Att det finns ett samspel mellan inflammation och blodets levringsförmåga (koagulation) är känt sedan länge. I det normala fallet pågår en konstant balansakt mellan inflammation och anti-inflammation, och mellan koagulation och anti-koagulation. Vid svår inflammation kan denna balans dock rubbas. I de allvarligaste fallen kan inflammationen leda till ett tillstånd av bildning av små proppar i blodkärlen i hela kroppen, där ämnen som behövs för att blodet ska levra sig konsumeras. Den uppkomna bristen på material som behövs för att blodet ska levra sig leder till samtidiga blödningar på andra ställen i kroppen. Med olika sorters blodförtunnande medicin (anti-koagulantia) har man kunnat påvisa en samtidig hämning av inflammation, vilket avspeglar det nära samarbetet som pågår mellan dessa system. Hur samspelet mellan koagulation och inflammation ser ut vid AP och vilken effekt anti-koagulantia har på det inflammatoriska svaret vid AP är knapphändigt studerat.&lt;br/&gt;&lt;br&gt; I detta avhandlingsarbete har anti-koagulation i form av en inaktiverad form av koagulationsfaktor VII (FVIIai) använts. Den normala formen av koagulationsfaktor VII (FVII) cirkulerar i blodet i en inaktiv form, som aktiveras och startar blodkoagulationen då den binds till vävnadsfaktor (tissue factor). Tissue factor (TF) är en bindnings- och signaleringsanordning som uttrycks på cellytan på en rad celler belägna utanför blodbanan och som exponeras då ett blodkärl går sönder. Man har även sett att vissa celler involverade i kroppens försvar, såsom vita blodkroppar och celler på insidan av kärl, kan uttrycka TF vid inflammation. Dessutom har man sett att FVII och TF inte bara kan starta blodkoagulation, utan också kan vara inblandade i en rad andra funktioner i kroppen, såsom reglering av inflammation, cellers rörlighet och tillväxt av vanliga celler och cancerceller.&lt;br/&gt;&lt;br&gt; I de tre första delarbetena i denna avhandling studeras behandlingseffekten av FVIIai i en modell på råttor, som ges en mycket svår form av AP. I det första arbetet studeras effekten då FVIIai ges som förbehandling, det vill säga innan råttan får AP. Resultaten visar att inflammationen lindrades i lungor och tarm samt att nivån av cirkulerande inflammatoriska ämnen i blodet (IL-6 och MIP-2) var lägre hos råttor som förbehandlats med FVIIai.&lt;br/&gt;&lt;br&gt; I det andra arbetet studeras huruvida aktiveringen av nuclear factor kappa B (NFκB) påverkas vid förbehandling med FVIIai hos råttor med svår AP. NFκB är en molekyl som finns i många av kroppens celler och som sköter reglering av hur gener uttrycks i cellerna, vilket i sin tur reglerar uttrycket av vissa inflammatoriska ämnen i kroppen. Resultaten visade att aktiveringen av NFκB var lägre hos råttor förbehandlade med FVIIai, vilket tyder på att hämning av NFκB utgör åtminstone en av verkningsmekanismerna för FVIIai:s inflammationsdämpande effekt.&lt;br/&gt;&lt;br&gt; I det tredje arbetet studeras effekten av efterbehandling med FVIIai, det vill säga behandling med FVIIai som ges till råttor som redan har svår AP. Detta scenario liknar mer verkligheten där man oftast inte kan behandla patienterna innan de blir sjuka. Resultaten visade en viss dämpad inflammation i lunga och en tendens till lägre nivåer av inflammatoriska ämnen i blodet. Effekten var dock betydligt mindre uttalad än när FVIIai gavs som förbehandling.&lt;br/&gt;&lt;br&gt; I det fjärde arbetet studeras förekomst av svåra blödningar hos patienter med AP. 1356 patientjournaler från 1994-2009 på alla patienter som vårdats i Lund med diagnosen AP gicks igenom. Resultaten visar att det är mycket ovanligt med svåra blödningar. Bara 14 patienter med svåra blödningar hittades. Trots att det är ovanligt med svåra blödningar vid AP kunde man konstatera att dödligheten bland dessa patienter var mycket hög och att stora resurser i form av operationer eller behandling via kärlröntgen (angiografi) ofta krävdes.&lt;br/&gt;&lt;br&gt; I det femte arbetet studeras nivåerna av TF i blodet hos 49 patienter med AP under de första tre dagarna på sjukhuset. Resultaten visar att TF är högre i gruppen av patienter som utvecklar en svår form av sjukdomen. Detta kan tyda på att TF är inblandat i utveckling av svår AP. När det gäller möjlighet att förutspå vilka patienter som kommer att få den svåra formen av sjukdomen visade sig nivån av TF vara bättre på att förutsäga detta än det kliniskt mest använda blodprovet, C-reaktivt protein (CRP), i prover tagna vid inkomst till sjukhuset. &lt;br/&gt;&lt;br&gt; Sammanfattningsvis dras slutsatserna:&lt;br/&gt;&lt;br&gt; - Att FVIIai har inflammationshämmande effekter i denna råttmodell av svår AP.&lt;br/&gt;&lt;br&gt; - Att NFκB-aktivering verkar vara en mekanism som påverkas av FVIIai.&lt;br/&gt;&lt;br&gt; - Att svåra blödningar hos patienter med AP är mycket ovanliga men svårbehandlade och riskfyllda.&lt;br/&gt;&lt;br&gt; - Att nivåerna av TF stiger tidigt vid AP och möjligen kan vara till hjälp för att förutsäga vilka patienter som kommer att utveckla svår AP.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b2850131-7aed-4f97-8a50-df379b476b87</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_A_garamond_G5_mall_169x239_mm_100726_Ellen_Andersson.pdf">https://portal.research.lu.se/files/3212739/1645813.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1248481</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Ellen Andersson</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>inflammation</topic> <topic>acute pancreatitis</topic> <topic>active site inactivated factor VII</topic> <topic>bleeding</topic> <topic>coagulation</topic> <topic>factor VII</topic> <topic>FVIIai</topic> <topic>hemorrhagic complications</topic> <topic>hemorrhage</topic> <topic>interleukin-6</topic> <topic>MIP-2</topic> <topic>nuclear factor kappa B</topic> <topic>tissue factor</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-95-5</identifier> <identifier type="oldLupId">1645799</identifier> <part> <detail type="volume"> <number>2010:79</number> </detail> <extent unit="pages"> <total>136</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-09-03T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>b2850131-7aed-4f97-8a50-df379b476b87</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:18+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:18+02:00</recordDateApproved> </recordInfo> </mods>

Two different approaches for mobile movement(polar and Cartesian)were used, combined with two different models for the received signal strength. The results of the simulation study showed better performance for particle filters based on a power model with varying propagation coefficient. The filters based on the polar model for mobile movement were found to be more precise in terms of mean squared error, but at the same time were more computationally intensive.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The second paper represents the results of a simulation study on mobile positioning in multiply input multiply output (MIMO) settings. Three different particles filters were implemented for the positioning, and simulation results showed that all filters were able to achieve estimation accuracy required by Federal Communication Commission (FCC). Moreover, since dimensionality of the particle filter state space does not depend on the antenna configuration, it is possible to apply described filters in more sophisticated MIMO setup without changing the algorithms.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the third paper we investigated an algorithm for particles filtering in multidimensional state-space models which are decomposable in the states. We demonstrated using the simulations that the algorithm effectively reduces the computational time without a large precision loss. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; It is known that the quality of sequential Monte Carlo estimation depends on the number of particles involved. In the paper four we explored different strategies to increase the number of particles: correlated sampling and observation-driven sampling. The correlated sampling approach was further investigated in the fifth paper, where we employed the idea of using antithetic variates. We introduced a version of the standard auxiliary particle filter and concluded, based on the theoretical developments, that the asymptotic variance of the produced Monte Carlo estimates can be decreased by means of antithetic techniques when the particle filter is closed to fully adapted, which involves approximation of the so-called optimal proposal kernel. As an illustration, the method was applied to optimal filtering in state-space models.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/34c13bb4-2659-4801-8ee7-8a34018dcfdf</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="SB_avhandlingen.pdf">https://portal.research.lu.se/files/3214141/1227796.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3365854</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Mathematical Statistics, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>positioning</topic> <topic>state-space models</topic> <topic>SMCM</topic> <topic>particle filtering</topic> </subject> <subject authority="lup"> <topic>Probability Theory and Statistics</topic> </subject> <relatedItem type="host"> <location> <url>http://www.maths.lth.se/matstat/staff/svetik/thesisSB.pdf</url> </location> </relatedItem> <relatedItem type="host"> <identifier type="isbn">978-91-628-7573-2</identifier> <identifier type="oldLupId">1227795</identifier> <part> <extent unit="pages"> <total>153</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-03T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>34c13bb4-2659-4801-8ee7-8a34018dcfdf</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:23+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:23+02:00</recordDateApproved> </recordInfo> </mods>

The structural and functional correlates of such impairments in preterm infants are incompletely understood, and early diagnostic tools are needed, but still lacking. Auditory event-related potentials (AERPs) are neurophysiological measures of cortical sound detection, encoding, discrimination, and attentional processes. Abnormal AERPs have been associated with cognitive and behavioral problems. To date, there has been very little research into AERP in preterm infants. Therefore, our aim was to investigate if AERPs in infants and children born very preterm correlate with cognitive outcome, and whether AERPs are related to findings on magnetic resonance imaging (MRI) at term. We investigated 70 children at 4-5 years of age who had been born very preterm, using AERPs and psychological testing, and compared them with more mature preterm and full-term children of the same age. Furthermore, we performed AERPs and MRI in another 42 very preterm infants at term, and these infants had a follow-up testing at 2 years of age.&lt;br/&gt;&lt;br&gt; AERPs at preschool age in children born very preterm showed abnormalities in comparison with more maturely born children. Similar abnormalities have been reported in full-term children with cognitive and behavioral problems (especially smaller amplitudes of early AERP deflections). Within the very preterm group, faster early sound processing was associated with better psychological test results, and sound differentiation was different between children with normal and abnormal test results. We showed that immaturity at birth, neonatal morbidity, and neonatal brain damage had an impact on different aspects of auditory processing, and that this impact still was present at 5 years of age. In the infants investigated at term age, we showed that later sound processing as well as sound differentiation has a high correlation with both cognitive and neurological outcome. Neonatal morbidity rather than prematurity itself had a strong impact on sound differentiation. AERPs showed stronger associations with outcome than brain volumes.&lt;br/&gt;&lt;br&gt; We conclude that AERPs are promising as a prognostic tool for outcome in very preterm infants. They can add considerably to established anatomical methods such as MRI. However, more research is needed before AERPs can be applicable in clinical praxis.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Barn födda före 32 gestationsveckor, även de utan svåra neurologiska avvikelser, har en hög förekomst av neuropsykologiska problem såsom läs-, inlärnings-, språk-, minnes- och beteendeproblem. Det är ännu inte klarlagt vilka funktionella och strukturella förändringar i hjärnan som orsakar dessa problem. Möjligheten till tidig diagnos behövs men saknas ännu.&lt;br/&gt;&lt;br&gt; Auditiva händelserelaterade potential (AERP) är neurofysiologiska mått på hjärnans reaktion på hörselstimuli och registreras med elektroencefalografi (EEG). I mer än 50 år har AERP använts i stor utsträckning i neuropsykologisk och utvecklingsforskning. De är uttryck för olika kortikala processer och representerar upptäckt av ljudet, dess analysering, jämförelse med andra och tidigare ljud och ljudrelaterad uppmärksamhet. Dessa processer är avgörande för omedveten orientering i en krävande ljudmiljö och för kognitiva processer som att lära sig språk. Hos fullgångna barn och vuxna har onormala AERP satts i samband med sådana kognitiva och beteendeproblem som ofta förekommer efter mycket för tidig födsel. Hittills har forskning om AERP hos prematura barn varit mycket begränsad. Därför var syftet med detta doktorsarbete att undersöka om AERP hos mycket prematurfödda förskolebarn skiljer sig från mognare prematura och fullgångna barn och om dessa skillnader korrelerar med kognitiv utveckling. Dessutom avsåg vi att utforska om AERP vid fullgången tid (40 graviditetsveckor) är av värde för att förutsäga utvecklingen i barnaåldern och hur AERP är relaterade till hjärnvolymer uppmätta med magnetresonanstomografi (MRT).&lt;br/&gt;&lt;br&gt; Vi undersökte 70 mycket prematurfödda barn i 4-5-års ålder och jämförde dem med mognare prematurfödda och fullgångna barn av samma ålder. Alla dessa barn genomgick AERP och psykologiska testmetoder. Dessutom utförde vi AERP-registrering och MRT hos ytterligare 42 mycket prematurfödda barn vid fullgången tid och följde upp barnen med psykologiska och neurologiska test vid 2-års ålder.&lt;br/&gt;&lt;br&gt; Våra resultat visade att mycket prematurfödda barn i förskoleåldern skiljer sig från barn födda senare i graviditeten avseende AERP och att deras AERP-avvikelser liknar dem man tidigare påvisat hos fullgångna barn med kognitiva och beteendeproblem. Framför allt har de lägre amplituder i tidiga AERP-vågor. Däremot hittade vi i denna ålder inga skillnader i deras förmåga att skilja åt olika ljud. Vi visade också att snabbare tidig ljudbearbetning inom den mycket prematurfödda gruppen var förenad med bättre psykologiska testresultat och att förmågan att skilja åt ljud skiljde sig mellan barnen med normala och abnorma testresultat. Sjukligheten i neonatalperioden påverkade bearbetningen av hörselintryck ännu i 5-års åldern och den påverkade andra kortikala processer än för tidig födsel eller hjärnskada diagnostiserad med ultraljud.&lt;br/&gt;&lt;br&gt; Hos spädbarnen som undersöktes med AERP vid fullgången tid visade vi att senare ljudbearbetningsprocesser (efter 250 ms) och åtskillnad av ljud har en stark korrelation med såväl kognitiv som neurologisk utveckling vid 2-års ålder. Dessutom var det snarare neonatal sjuklighet än prematuritet i sig som förändrade förmågan att skilja mellan ljud. AERP visade starkare koppling till utvecklingen vid denna ålder än hjärnvolymer. Hjärnvolymerna korrelerade dock med koncentrationerna av tillväxtfaktorn Insulin-like growth factor-I i neonatalperioden till skillnad från AERP.&lt;br/&gt;&lt;br&gt; Vi drar slutsatsen att AERP bör kunna utvecklas till en lovande metod för att förutsäga den senare utvecklingen hos mycket prematura barn och att denna metod kan ge viktig information utöver den som erhålls med anatomiska metoder som MRT. Ytterligare forskning behövs dock innan AERP kan bli användbart i klinisk praxis.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/09484722-a70a-4004-9a13-83d1fc32a89e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Holger_HAPvel.pdf">https://portal.research.lu.se/files/3214178/5149153.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">25260731</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Preterm</topic> <topic>Event-related potentials</topic> <topic>Mismatch negativity</topic> <topic>Magnetic resonance imaging</topic> <topic>developmental outcome</topic> </subject> <subject authority="lup"> <topic>Pediatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-109-5</identifier> <identifier type="oldLupId">5149151</identifier> <part> <detail type="volume"> <number>2015:30</number> </detail> <extent unit="pages"> <total>202</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-03-28T10:00:00+01:00</dateOther> <note type="additionalInfo">Authors Ingrid Hansen-Pupp and Holger Hövel contributed equally to paper 3.</note> <recordInfo> <recordIdentifier>09484722-a70a-4004-9a13-83d1fc32a89e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:05:11Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:24+02:00</recordDateApproved> </recordInfo> </mods>

This fusion gene is important for leukemia development but is not sufficient for leukemia to arise. Hence, the additional genetic changes present in leukemic ETV6/RUNX1-positive cells give important clues regarding the history of the leukemia. The aim of this thesis has been to characterize thoroughly the genetic changes present in ETV6/RUNX1-positive ALL. In Article I, seventeen ETV6/RUNX1-positive ALLs were characterized using array CGH. This revealed that gain of Xq material, present in six cases, was the most common copy number aberration (CNA). A large number of genes was present in the commonly gained region but the high and specific expression of SPANXB identified this gene as a likely target of the gain. In Article II, 24 ALLs were analyzed using 500K single nucleotide polymorphism arrays. The data from these ALLs were combined with previously published external SNP array data from 140 ETV6/RUNX1-positive ALLs. A high number of recurrent CNAs could be identified in this dataset. The recurrent CNAs were further analyzed using hierarchical clustering, connected pair analysis, and oncogenetic tree models. These analyzes revealed that the majority of cases had acquired a unique set of recurrent CNAs, indicating that the process of acquiring CNAs is unique for each ALL. In Article III, exome sequencing was used to sequence all protein coding genes in two ETV6/RUNX1-positive ALLs. Seven somatic single nucleotide mutations were present in each ALL, six of these were in genes previously implicated in cancer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7961898b-a218-45c4-8ac7-655a01f54588</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Henrik_Lilljebjorn.pdf">https://portal.research.lu.se/files/3214386/1787229.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">723967</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>SNP array</topic> <topic>array CGH</topic> <topic>ETV6/RUNX1-positive ALL</topic> <topic>childhood ALL</topic> <topic>exome sequencing</topic> </subject> <subject authority="lup"> <topic>Medical Genetics and Genomics (including Gene Therapy)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-67-9</identifier> <identifier type="oldLupId">1787221</identifier> <part> <detail type="volume"> <number>2011:18</number> </detail> <extent unit="pages"> <total>61</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-03-11T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>7961898b-a218-45c4-8ac7-655a01f54588</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:28+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:28+02:00</recordDateApproved> </recordInfo> </mods>

Breast tomosynthesis takes advantage of multiple exposures at different angles reducing the negative effect of obscuring tissue. The aim of this thesis was to investigate the use of tomosynthesis in breast imaging with a special focus on the role of tomosynthesis in screening.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Papers I and II was based on 7,500 women comprising the first half of the Malmö Breast Tomosynthesis Screening Trial (MBTST): a prospective population-based single arm study including randomly invited women 40–74 years old eligible for the screening programme in the city of Malmö. Women underwent one-view tomosynthesis with reduced compression force and mammography. The images were read and scored separately in a blinded double-reading procedure. The increase in cancer detection rate (6.3 to 8.9/1,000) and recall rate (2.6% to 3.8%) using tomosynthesis was significant (p&amp;lt;0.0001). The additional cancers detected were mainly invasive, with a tendency of downstaging (Paper I). Findings of stellate distortion simulating malignancy increased the false positive rate with tomosynthesis. The false positive rate was reduced over time, suggesting a learning curve (Paper II).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper III was a human observer study designed to study the effect of different viewing procedures (free scroll volume browsing and initial cineloops at three different frame rates) and image orientations (vertical and horizontal) on reading performance. 40 three-dimensional simulations of breast malignancy were inserted in 55 normal tomosynthesis image volumes, creating four unique image sets, one for each viewing procedure. Detection accuracy was similar for the different reading conditions but reading time and visual attention were improved for horizontally oriented images.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In Paper IV, 26 breast cancers subjected to discrepant detection in tomosynthesis and mammography in a previous reader study with 185 cases with normal and diseased breasts (95 cancer lesions), were analysed in a side-by-side review to assess factors related to lesion visibility and possible reasons for detection error. Breast cancers imaged with tomosynthesis were found to be more conspicuous with a higher proportion of discernable lesion periphery. Missing a cancer in tomosynthesis seemed to be related to interpretative error of visible lesions.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, one-view tomosynthesis, with reduced compression force, might be sufficient as a stand-alone screening modality.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bröstcancer är kvinnans vanligaste cancerform och globalt sett den cancer som leder till flest dödsfall. Bröstcancerscreening med mammografi används därför i syfte att hitta cancern tidigt. En tidigt upptäckt cancer har oftast en bättre prognos med möjlighet att minska dödligheten i bröstcancer. Mammografitekniken är dock behäftad med vissa begränsningar vad gäller känsligheten att upptäcka tumörer. En avgörande nackdel är att mammografibilden är en tvådimensionell avbild av ett tredimensionellt bröst vilket gör att överlappande vävnad kan dölja en tumör.&lt;br/&gt;&lt;br&gt; Brösttomosyntes är en utveckling av den konventionella mammografin, där ett flertal bilder tas medan röntgenapparaten sveper över bröstet i en båge. Med detta förfarande skapas en tredimensionell representation av bröstet i form av en hög med millimetertunna bildsnitt, vilka inte är begränsade av överlappande vävnad i samma utsträckning som mammografi. Brösttomosyntes har också visat sig vara en mer känslig metod än mammografi att hitta tumörer. Huruvida tomosyntes skulle kunna användas i bröstcancerscreening är följaktligen en aktuell frågeställning, vilken har legat till grund för detta avhandlingsarbete (Arbete I–IV).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arbete I och II är baserade på Malmö Breast Tomosynthesis Screening Trial (MBTST), en prospektiv populationsbaserad screeningstudie. I MBTST erbjöds kvinnor, som var aktuella för mammografiscreening i Malmö, att även undersökas med tomosyntes. Två oberoende röntgenläkare granskade mammografi- och tomosyntesbilderna separat med uppgift att hitta misstänkta cancrar och bestämma vilka kvinnor som skulle återkallas för vidare utredning. Analysen av första hälften av MBTST bestod av 7500 kvinnor och visade att tomosyntes upptäckte 8,9 cancrar per 1000 undersökta kvinnor jämfört med 6,3 per 1000 med mammografi, vilket innebar att tomosyntes hittade 21 fler cancrar. Återkallningen av kvinnor ökade också, men var fortfarande låg: 3,8% med tomosyntes jämfört med 2,6% med mammografi. Tomosyntesscreening ledde också till en ökning av misstänkta fynd som efter utredning visade sig vara normal vävnad eller ofarliga förändringar, så kallat falskt positiva. Dessa utgjordes framför allt av röntgenfynd med strålig konfiguration som efter utredning kunde avfärdas som normal vävnad. Röntgenläkarna blev dock bättre på att karakterisera fynd på tomosyntes under studiens gång vilket resulterade i att andel falskt positiva sjönk.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Om tomosyntes ska användas i screening framträder den långa granskningstiden som en utmaning. Det tar ungefär dubbelt så lång tid för röntgenläkaren att granska en tomosyntesundersökning jämfört med mammografi. Det är därför viktigt att undersöka hur granskningstiden kan minskas. Röntgenbilder brukar granskas vertikalt orienterade, men hypotetiskt sett borde horisontellt orienterade bilder passa vårt synfält bättre.&lt;br/&gt;&lt;br&gt; I arbete III studerades sätt att påverka granskningstiden genom olika bildpresentationer (vertikalt eller horisontellt orienterade) och granskningsförfarande (fritt sökande i djupled med ”scrollning” eller med filmloopar i tre olika hastigheter följt av scrollande). Fyra granskare hade fått i uppgift att hitta tumörer. Medan granskarna letade efter tumörerna registrerades deras ögonrörelser. Studien visade att horisontellt orienterade tomosyntesbilder kan ge förbättrade granskningsförhållanden, med minskad granskningstid och ökat utnyttjande av synfältet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I arbete IV undersökte vi bröstcancrar avbildade med tomosyntes och mammografi som bara hade upptäckts med den ena metoden. Syftet var att beskriva tumörernas synlighet med de olika teknikerna och att försöka förstå den bakomliggande orsaken till att tumören hade missats. Vi fann att tumörerna var mer iögonfallande med tomosyntes jämfört med mammografi, på grund av den ökade friprojiceringen. Orsaken till att cancrar trots detta missades med tomosyntes antogs bero på tolkningsfel av synliga tumörer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den övergripande slutsatsen i denna avhandling är att brösttomosyntes kan vara en lämplig framtida bröstcancerscreeningmetod.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9124054f-3c34-4118-b42b-5f3a0ed8a373</url> </location> </relatedItem> <originInfo> <publisher>Department of Translational Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Breast cancer</topic> <topic>Breast tomosynthesis</topic> <topic>Mammography</topic> <topic>Breast cancer screening</topic> <topic>Cancer detection rate</topic> <topic>Recall rate</topic> <topic>False positive rate</topic> <topic>Image perception</topic> <topic>Reading time</topic> <topic>Lesion visualisation</topic> <topic>Detection error</topic> </subject> <subject authority="lup"> <topic>Radiology and Medical Imaging</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-193-4</identifier> <identifier type="oldLupId">8080781</identifier> <part> <detail type="volume"> <number>2015:114</number> </detail> <extent unit="pages"> <total>67</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-11-13T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>9124054f-3c34-4118-b42b-5f3a0ed8a373</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:31+02:00</recordDateApproved> </recordInfo> </mods>

There are many forms of cancer, which is a genetic disease, believed to result from a multistep process with genetic and epigenetic changes accumulating over time. Breast cancer is one of the most common forms of cancer in women, while it is much more rare in men. Male breast cancer (MBC) exhibits both similarities and differences with female breast cancer (FBC). However, in contrast to FBC, MBC is poorly characterized on the molecular level. Multiple global profiling studies of FBC have been performed on the genetic and epigenetic levels, while only a few genetic studies have been performed on MBC. &lt;br/&gt;&lt;br&gt; The aim of the research presented in this thesis was to study MBC on the genomic, transcriptomic and epigenomic levels, in an attempt to reveal some of the mechanisms of tumorigenesis in MBC, and to provide a detailed molecular landscape of the disease, allowing comparisons with FBC. The various studies were carried out using high-resolution microarrays and immunohistochemistry on a well-annotated cohort of MBC patients from whom 83 fresh frozen and 220 formalin-fixed paraffin-embedded samples were available. &lt;br/&gt;&lt;br&gt; It was found that MBC is heterogeneous on a genomic, transciptomic and epigenetic level, consisting of various kinds of tumors, each of which exhibits its own aberrations, as is the case in FBC. Male and female breast cancer tumors had a similar appearance on a global level, but when studied in greater detail, many genetic and epigenetic differences were revealed. Furthermore, the landscapes of candidate drivers in male and female breast cancer appear to show considerable differences. Attempts were made to subclassify the fresh frozen MBC tumors with regard to copy number, and levels of mRNA and DNA methylation. Two stable subgroups were consistently identified, showing differences in the biological features of the tumors, where one of the subgroups seemed to consist of a number of more aggressive MBC tumors. The subgroups from the three datasets analyzed were significantly associated with each other, however, they differed from the known subgroups of FBC. As such, they may constitute two novel subgroups of breast cancer, occurring exclusively in men. This indicates that breast cancer in men may require different management and treatment strategies from those used in women with breast cancer.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bröstcancer är den vanligaste cancerformen hos kvinnor i Sverige, men även män kan drabbas. Hos män är det dock en mycket ovanlig cancerform. I Sverige insjuknar cirka 40 män per år av bröstcancer jämfört med cirka 8000 kvinnor per år. Bröstcancer hos män och kvinnor är på många sätt lika. Till exempel är sjukdomstecknen desamma och visar sig oftast som en knöl eller knuta i bröstet. Emellertid finns det även en hel del skillnader, som att män oftast är äldre än kvinnor när de drabbas av bröstcancer. De flesta män som drabbas är 60–70 år eller äldre. Risken för att män ska drabbas av bröstcancer ökar bland annat om de har en obalans av könshormonerna, något som kan uppkomma vid bland annat övervikt och leversjukdomar. En annan riskfaktor är om man har en familjehistoria med många bröstcancerfall och/eller äggstockcancerfall inom familjen, eftersom det finns vissa former av bröstcancer som är ärftliga hos både kvinnor och män.&lt;br/&gt;&lt;br&gt; På grund av att manlig bröstcancer är en så pass ovanlig tumörform har det inte studerats så mycket. Därför finns det stora kunskapsluckor om hur manlig bröstcancer fungerar och hur patienterna ska behandlas på bästa sätt. Många känner inte till att även män kan utveckla bröstcancer, och därför är ofta män mindre uppmärksamma på förändringar i deras bröst än kvinnor. Detta leder till att bröstcancertumörer hos män ibland upptäcks i ett senare skede än hos kvinnor och har då hunnit bli mer aggressiva. Möjligheten att bota bröstcancer är större ju tidigare en diagnos ställs. Idag får manliga bröstcancerpatienter samma behandling som kvinnliga bröstcancerpatienter. En svensk studie har visat att även om män får samma behandling som kvinnor med bröstcancer, så har männen sämre överlevnad. Det gäller också om man enbart jämför kvinnor och män i samma ålder. &lt;br/&gt;&lt;br&gt; Bröstcancer är inte bara en sjukdom utan många olika sjukdomar. Beroende på vilken sorts bröstcancer man har behöver man olika sorters behandling. Idag har man lyckats dela in kvinnlig bröstcancer i olika undergrupper som fungerar olika biologiskt, är olika aggressiva och där patienterna har olika chans att överleva. Bröstcancerbehandlingar idag går ut på att ge varje patient en individuell behandlingsplan beroende på patientens hälsotillstånd och vilken form av bröstcancer de har. Till sin hjälp har läkarna idag ett antal faktorer hos patienten och tumören som de kan använda sig av för att bestämma vilken behandling som skall ges i tillägg till kirurgi. Många bröstcancerpatienter blir friska idag, men tyvärr inte alla. Varje år i Sverige dör 1400 kvinnor och 15 män av bröstcancer. En av de stora utmaningarna idag är att veta vilken patient som kommer att ha nytta av vilken behandlingsplan. Många bröstcancerpatienter idag skulle bli friska med enbart kirurgi, men på grund av att vi inte vet vilka och att vi vill förhindra återfall hos så många som möjligt behandlas många bröstcancerpatienter i onödan med tuffa tilläggsbehandlingar. Tilläggsbehandlingar kan bestå av strålning eller vara någon form av medicinska tilläggsbehandlingar som endokrin behandling, cytostatika och/eller målinriktade behandlingar. Det finns ett behov av att hitta nya faktorer som bättre kan identifiera vilka patienter som har hög risk för återfall och som därför är i störst behov av mer omfattande tilläggsbehandlingar. &lt;br/&gt;&lt;br&gt; Cancer är ett samlingsnamn för flera hundra olika sjukdomar och de är genetiska sjukdomar som uppkommer genom att kroppens egna celler har samlat på sig många genetiska förändringar vilket slutligen leder till att de börjar dela sig okontrollerat och inte följer kroppens signaler längre. När kroppens kontroll över cancercellerna är satt ur spel kan de dela sig obegränsat antal gånger och deras dotterceller ärver deras genetiska förändringar. När en cancercell har uppnått förmågan att växa invasivt och kan sprida sig är det en malign tumör. Tumörer som inte kan sprida sig kallas benigna. Maligna tumörer kan till slut sprida sig till andra platser i kroppen och bilda nya tumörer (metastaser). &lt;br/&gt;&lt;br&gt; I de fyra delarbetena som ingår i denna avhandling har vi studerat ett stort material av 220 paraffininbäddade och 83 färskfrysta manliga bröstcancertumörer som vi har samlat in från södra Sverige och Uppsala-regionen mellan 1983 och 2009. Dessutom har vi samlat in information om tumörerna och patienterna. De färskfrysta tumörerna använde vi för att studera hur manliga bröstcancertumörer fungerar biologiskt och jämförde dem med kvinnliga bröstcancertumörer. Vi har studerat hela arvsmassan av tumörerna på tre olika nivåer: &lt;br/&gt;&lt;br&gt; • Mönster av ökningar eller förluster av arvsmassan (DNA). Arvsmassan innehåller all information om kroppens alla celler och finns normalt i två kopior i varje cell.&lt;br/&gt;&lt;br&gt; • Mönster av genaktiviteten (mRNA). Arvsmassan innehåller gener och olika celler i kroppen använder sig av olika gener. Generna i sin tur utgör ritningar för proteiner som utför allt arbete i cellerna och bygger upp kroppen. &lt;br/&gt;&lt;br&gt; • Mönster av en specifik epigenetisk förändringar (DNA metylering). Epigenetiska förändringar är ett av kroppens system för att bestämma vilken gener som ska användas.&lt;br/&gt;&lt;br&gt; De paraffininbäddade manliga bröstcancertumörerna använde vi för att studera proteiner.&lt;br/&gt;&lt;br&gt; Genom dessa studier har vi kunnat se att manlig bröstcancer liksom kvinnlig bröstcancer är en mycket heterogen sjukdom med mycket förändringar på de tre nivåerna. Rent generellt liknar förändringarna i manlig bröstcancer förändringarna i kvinnlig bröstcancer på alla tre nivåerna. När förändringar studerades mer i detalj hittade vi dock många skillnader mellan manlig och kvinnlig bröstcancer. Som exempel innehåller de manliga bröstcancertumörerna fler ökningar och färre förluster av arvsmassan än de kvinnliga bröstcancertumörerna. &lt;br/&gt;&lt;br&gt; Ett av huvudmålen i avhandlingen har varit att dela upp de manliga bröstcancertumörerna i olika undergrupper, precis som man tidigare gjort med kvinnlig bröstcancer. Genom våra mätningar på de tre olika nivåerna har vi hitta två stabila undergrupper. De två identifierade undergrupperna av manlig bröstcancer fungerar olika biologiskt, är olika aggressiva och patienterna har olika chans att överleva. Dessa undergrupper verkar inte vara representerade bland undergrupperna för kvinnlig bröstcancer. Troligen finns därför dessa två nya grupper av bröstcancer bara hos män, och därför kan män med bröstcancer tänkas behöva andra behandlingsstrategier än kvinnor. &lt;br/&gt;&lt;br&gt; Mer än 90% av de manliga bröstcancertumörerna har receptorer för det kvinnliga könshormonet östrogen, jämfört med de kvinnliga bröstcancertumörerna där cirka 75-80% av dem har östrogenreceptorer. Man vet att hos kvinnor med bröstcancertumörer med östrogenreceptorer så är tumörerna ofta beroende av östrogen för sin tillväxt och överlevnad. En mycket effektiv behandlingsmetod är att blockera tillförseln av östrogen genom endokrin behandling, till exempel med läkemedlet tamoxifen. Om risken för återfall bedöms som hög erbjuds bröstcancerpatienter även mer intensiva tilläggsbehandlingar som cytostatika och/eller målinriktade behandlingar. För manlig bröstcancer vet man inte säkert om endokrin behandling är lika effektivt, men några små studier har visat att en del manliga bröstcancertumörer med östrogenreceptorer svarar på behandling med tamoxifen. I den mer aggressiva undergruppen av manlig bröstcancer fann vi något oväntat, att även om de har östrogenreceptorer så verkar tumörerna inte fungera på samma sätt som kvinnliga bröstcancertumörer med östrogenreceptorer. Detta kan innebära att tumörerna inte är beroende av östrogen för sin tillväxt och överlevnad, och att de därför inte svarar lika bra på endokrin behandling. Dessa manliga bröstcancerpatienter skulle därför kanske behöva andra behandlingsstrategier än endokrin behandling. Bland de manliga bröstcancerpatienterna vars tumörer tillhörde den mer aggressiva gruppen, fick bara 12% tilläggsbehandling med cytostatika och det är mycket troligt att fler patienter i den gruppen skulle ha behövt tillägg av cytostatika. De faktorer som idag används för att bestämma behandlingsplan för manlig bröstcancer räcker inte till för att hitta alla patienter som behöver de mer intensiva tilläggsbehandlingarna, och nya faktorer behöver identifieras. Vi har hittat en ny lovande faktor, NAT1. I vårt material såg vi att om tumörerna har NAT1-proteiner så har patienterna en mycket lägre risk för återfall. Majoriteten av de manliga bröstcancertumörerna i den aggressiva undergruppen har inte NAT1-proteiner. Detta gör NAT1 till en mycket intressant faktor att studera vidare och i framtiden eventuellt kunna använda den för att bestämma vilken behandling som skall ges i tillägg till kirurgi till män med bröstcancer. &lt;br/&gt;&lt;br&gt; Sammanfattningsvis så har vi visat att manlig bröstcancer skiljer sig mer från kvinnlig bröstcancer än vad man tidigare trott. Vi har också identifierat två undergrupper av manlig bröstcancer med olika biologiska egenskaper och olika överlevnads chans för de drabbade patienterna. Dessa undergrupper verkar inte vara representerade bland undergrupperna för kvinnlig bröstcancer. Våra resultat visar att män med bröstcancer kan tänkas behöva andra behandlingsstrategier än kvinnor med bröstcancer. Vi har identifierat NAT1 som en lovande faktor att använda sig av för att bestämma behandlingsstrategi för män med bröstcancer. Om de manliga bröstcancertumörerna inte har NAT1 proteiner så har patienterna en mycket högre risk att utveckla återfall.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5a9da89e-c480-4301-bd9d-2f28588e59f3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis_Ida_Johansson.pdf">https://portal.research.lu.se/files/3214602/4153509.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8554496</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Oncology, Lund</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>male breast cancer</topic> <topic>aCGH</topic> <topic>gene expression</topic> <topic>DNA-methylation</topic> <topic>microarray</topic> <topic>profiling</topic> <topic>NAT1</topic> <topic>THY1</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-04-5</identifier> <identifier type="oldLupId">4153506</identifier> <part> <detail type="volume"> <number>2013:129</number> </detail> <extent unit="pages"> <total>87</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-12-06T13:30:00+01:00</dateOther> <recordInfo> <recordIdentifier>5a9da89e-c480-4301-bd9d-2f28588e59f3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:32+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:32+02:00</recordDateApproved> </recordInfo> </mods>

Small reactive organic molecules called haptens induce ACD. Haptens are not recognized by themselves, but need to bond to endogenous proteins in the skin, and processed further into complete antigens. Antigen specific T cells then recognize the resulting antigen. Although the haptens are well known, the chemical reactions of haptens inducing ACD is not well known. Neither are the chemical structures of the complete antigens associated with ACD in humans.&lt;br/&gt;&lt;br&gt; This study is composed of three parts. Reactivity study of strong sensitizers like 2,4-dinitrofluorobenzene (DNFB), 1,4-benzoquinone (BQ), 4-t-butyl-1,2-benzoquinone (tBuBQ) and cis-1,2-hexahydrophthalic-anhydride (HHPA) under physiologic conditions with nucleophilic amino acids and peptides by analytical methods (HPLC, LC/MS/MS). The new reaction products were isolated and their structures were determined by NMR and MS. We found that most haptens reacted predominantly with cystein and cystein containing peptides.&lt;br/&gt;&lt;br&gt; We then synthesized an array of 2,4-dinitrophenyl- (Dnp) modified collagen II peptides, as complete antigens, by solid phase peptide synthesis (SPPS). In a MHC class II (H2-Aq) restricted T cell model of ACD, we evaluated the responses of these antigens. The length of the amino acid side chain bonding the Dnp-group determined the T cell response. Substitution of lysine for ornithine gave a complete loss of T cell recognition. &lt;br/&gt;&lt;br&gt; We finally used homology modeling to construct a model of the H2-Aq/antigen/TCR complex, a part of the ”immunological synapse”. Our new model could explain the experimental T cell responses in terms of a defined structure of the MHC/antigen, and how this structure is displayed for the TCR. This study may contribute to better diagnosis, and possibly a cure of ACD in the future.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0d3fc213-58f7-4de6-9a9b-868d86f710fd</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Stefan_Ahlfors.pdf">https://portal.research.lu.se/files/3214742/1261462.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1738706</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>hypersensitivity</topic> <topic>adduct</topic> <topic>immune response.</topic> <topic>Allergy</topic> <topic>hapten</topic> </subject> <subject authority="lup"> <topic>Dermatology and Venereal Diseases</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-58-3</identifier> <identifier type="oldLupId">1261451</identifier> <part> <detail type="volume"> <number>2008:105</number> </detail> <extent unit="pages"> <total>110</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-11-21T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>0d3fc213-58f7-4de6-9a9b-868d86f710fd</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:34+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:34+02:00</recordDateApproved> </recordInfo> </mods>

Incomplete recovery is considered to be the most important link between acute physiological stress reactions, shift work and chronic health effects. Mental and physiological activation naturally accompanies night-call duty, but the crucial issue, from a health perspective, is whether the activation is sustained post-call. Studies of physicians show that night-call duty can be detrimental to subjective health and performance. However, less is known about the physiological effects of working on night call, and whether the effects of such duty differ across medical specialities. For anaesthesiologists on night-call, the mental load of constantly handling patients with life-threatening conditions may have a greater impact on their recovery compared with other specialists. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the present field study 19 anaesthesiologists were compared with18 paediatricians and ear, nose, and throat surgeons. They all had 16-hour night-call duties at a university hospital. The aims were to determine whether a sufficient physiological recovery would be attained within 1-3 days after night-call duty, and whether recovery patterns differed across medical specialities. Several physiological systems were monitored by repeated measures on ordinary daytime work, during night-call duty and during post-call. Cortisol was analysed in saliva, and other metabolic factors were analysed in blood samples. Sleep was monitored with actigraphy and ambulatory electrocardiographic recordings were used to measure heart rate variability (HRV), to determine autonomic balance.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The results suggested no general metabolic change after night-call duty. Recovery sleep after night call was considered sufficient, but sleep after daytime work was unexpectedly short. HRV patterns did not indicate a deficient recovery, but possibly a higher physiological stress level in anaesthesiologists. The 16-hour night-call schedules seemed compatible with a short-term physiological recovery within two days after night-call duty, but the limited sleep after ordinary daytime work may constitute a long-term health concern. All these results contribute to our knowledge of how to plan sustainable night-call working schedules, and further investigation is needed to determine whether these results can be generalized to other work settings and specialists.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Läkares nattjour innebär långa arbetspass, höga krav, stress och sömnbrist. I dagens läge liknar nattjouren ofta ett nattskift med begränsade möjligheter till vila under arbetspasset. Skiftarbete med nattskift har i många undersökningar visats ge ökad risk för bland annat hjärtinfarkt och diabetes, samt även ha en negativ inverkan på välbefinnande och sömn. Samtliga dessa effekter anses bero på en störning av sömn och dygnsrytm, men sannolikt är orsakerna mer komplexa. Det har diskuterats om nattjoursarbete skulle kunna innebära liknande risker. Eftersom läkares jourpass är betydligt längre och dessutom mer oregelbundna än vid sedvanligt skiftarbete är det problematiskt att göra direkta jämförelser. Långa nattjourspass ger ofta en akut ökad trötthet som påverkar subjektivt välbefinnande och arbetsprestation. Dock är fysiologiska effekter och tänkbara långsiktiga hälsoeffekter av nattjoursarbete ytterst ringa studerat.&lt;br/&gt;&lt;br&gt; Det kan förväntas att ett nattjourspass innebär en påtaglig belastning både mentalt och fysiologiskt. Det viktiga ur hälsosynpunkt är dock att man får en adekvat återhämtning efter jouren. Det är nämligen vanligtvis inte belastningen i sig utan upprepade episoder med bristande återhämtning som i ett långsiktigt perspektiv kan leda till sjukdom. Många läkare upplever nattjourtjänstgöringen som en mycket belastande del av arbetet. I jämförelse med det stora antal studier som finns av skiftarbete inom industrin är den speciella typ av skiftarbete som läkares nattjour innebär till stora delar ännu outforskad. Initiativet till de studier som avhandlingen bygger på kom från en grupp av anestesiläkare som var oroliga över potentiella hälsoeffekter av en tilltagande jourbörda.&lt;br/&gt;&lt;br&gt; En omfattande fältundersökning av läkare med 16-timmars nattjour genomfördes år 2002 på Universitetssjukhuset i Lund. Deltagarna bestod av en grupp med 19 anestesiläkare och en grupp med 18 barnläkare och öron-näsa-hals-läkare. Läkarna var i genomsnitt 40 år och de flesta hade mångårig erfarenhet av nattjour. Anestesiläkare har rapporterats ha en hög belastning under nattjour. Det ständiga handhavandet av patienter med livshotande tillstånd skulle kunna tänkas medföra ett större behov av återhämtning efter nattjour än inom många andra specialiteter. Den huvudsakliga frågeställningen var om aktuella nattjourscheman gav utrymme för en adekvat återhämtning inom 1-3 dagar efter nattjour och om det fanns någon skillnad i återhämtningsmönster mellan de två studerade läkargrupperna.&lt;br/&gt;&lt;br&gt; I studien undersöktes ett flertal fysiologiska system, som är kända för att påverkas av stress, nattarbete och sömnbrist. Upprepade mätningar vid dagarbete, nattjour och återhämtningsperioden efter nattjour gjordes enligt följande: blodprov för analys av metabola faktorer såsom blodsocker, blodfetter och sköldkörtelhormon; salivprov för fastställande av kortisolhalt; indirekt mätning av sömnlängd via detektion av handledsrörelser (aktigrafi); elektrokardiografi (EKG) för analys av hjärtfrekvensvariationer (Heart Rate Variability, HRV). Förutom denna provtagning fick deltagarna dagligen fylla i ett flertal frågeformulär med skattning av trötthet, sömnighet och upplevd återhämtning.&lt;br/&gt;&lt;br&gt; De kemiska analyserna och de fysiologiska registreringarna indikerade att läkarna återhämtat sig till fullo två dagar efter nattjour. Det framkom inga omfattande skillnader mellan de två läkargrupperna avseende återhämtningsmönster. Vad gäller variationer i hjärtfrekvens hade anestesiläkarna tecken på en högre fysiologisk stressnivå, men ingen av läkargrupperna visade en bristande återhämtning efter nattjour. Sömnen under nattjour var endast cirka tre timmar i genomsnitt, vilket dock var förväntat. Återhämtningen av sömn efter nattjour, både i form av extra tupplur på dagtid efter jourpasset och nattsömn efter jour, bedömdes som tillräcklig. Dock visade det sig att läkarnas nattsömn endast var ca sex timmar efter en vanlig arbetsdag, vilket var överraskande. &lt;br/&gt;&lt;br&gt; De 16-timmars scheman för nattjour som undersöktes verkade visserligen vara förenliga med en tillräcklig kortsiktig fysiologisk återhämtning inom 2 dygn, men den begränsade nattsömnen efter vanligt dagarbete skulle kunna ge en långsiktig påverkan på hälsan. Det bör påpekas att nattjoursarbetets struktur och innehåll kan ha avsevärda variationer beroende på specialitet. Detta innebär att de aktuella resultaten inte automatiskt kan generaliseras till nattjoursjourarbete i allmänhet. Man kan dessutom inte utesluta att läkare med kort erfarenhet av nattjour hade uppvisat ett annat återhämtningsmönster. Den observerade tiden för återhämtning stämmer väl med den erfarenhet som finns från undersökningar av skiftarbetare, men någon motsvarande studie av läkares återhämtning efter nattjour finns inte att jämföra med.&lt;br/&gt;&lt;br&gt; Erfarenheterna från de aktuella undersökningarna bör kunna utnyttjas både vid rådgivning kring schemafrågor inom sjukvården och även på sikt förhoppningsvis kunna bidra till att skapa scheman som minimerar risker för ohälsa. I den aktuella studien var antalet deltagare av praktiska skäl begränsat, vilket gör att resultaten skall tolkas med viss försiktighet. Man kan även tillägga att det finns avsevärda individuella skillnader i tolerans för nattarbete, som inte närmare undersökts. Därför behövs fler studier av ffa läkares sömn i anslutning till nattjour och jämförelser mellan olika schematyper för att få ett bättre underlag för planering av nattjoursystem som tillåter en adekvat återhämtning. Detta är en förutsättning för en god arbetsmiljö för läkare och ett effektivt omhändertagande av patienter.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/81ecc980-f72c-432a-9955-d0ed91f51ffc</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Birgitta_Malmberg_avh.pdf">https://portal.research.lu.se/files/3215238/3561533.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">731498</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>HRV</topic> <topic>Acitwatch</topic> <topic>night-call</topic> <topic>anaesthesiologist</topic> <topic>sleep</topic> <topic>working time</topic> </subject> <subject authority="lup"> <topic>Occupational Health and Environmental Health</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-18-15</identifier> <identifier type="oldLupId">2064681</identifier> <part> <detail type="volume"> <number>2011:68</number> </detail> <extent unit="pages"> <total>68</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-09-15T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>81ecc980-f72c-432a-9955-d0ed91f51ffc</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:43+02:00</recordDateApproved> </recordInfo> </mods>

A novel method was developed in this study based on the expression of P2X2 receptor channel in secreting cells. The presence of ATP sensitive channel on the cell membrane permitted the electrical detection of minute (amoles) quantities of ATP and thus created a possibility to measure ATP released from a single insulin granule.&lt;br/&gt;&lt;br&gt; The release of peptides and low molecular weight substances was explored by combining the detection of exocytotic events by P2X2 receptor method with imaging of secretory granules. It was found that in rat insulinoma cells these substances were released independently and with different time course: nucleotides - 280 ms and granular peptide marker IAPP - 2.2 s after the membrane depolarization. In 72% of all exocytotic events nucleotide release was not followed by the discharge of peptide cargo.&lt;br/&gt;&lt;br&gt; The chief inhibitory neurotransmitter gamma-aminobutyric acid (GABA) is also found in pancreatic β-cells though its role in coordinating processes in the pancreas is unknown. Sub-cellular localization has not been fully resolved too. Electrical measurements of ATP, GABA and 5-HT release in rat pancreatic β-cells allowed us to demonstrate that at least 75% of GABA release events were attributable to the exocytosis of large dense core vesicles in these cells and its selective release was regulated by the size of the fusion pore.&lt;br/&gt;&lt;br&gt; The combination of the cell capacitance measurements, the electrical measurements of ATP release and amperometric detection of 5-HT release demonstrated that in rat pancreatic β-cells ATP is stored and released by large dense core vesicles. The contribution of small synaptic like vesicles is below the detection levels of methods used.&lt;br/&gt;&lt;br&gt; The possibility of multi-vesicular exocytosis in pancreatic β-cells was explored by the cell-attached capacitance measurements, the total internal reflection microscopy and by electrical ATP release measurements. It was found that global increase in [Ca2+]i promotes the formation of complexes of interconnected granules within cell cytoplasm that subsequently undergo exocytosis as one unit. This may lead to exocytosis of up to 15 granules simultaneously (compound exocytosis).</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b87bfbec-9a17-4048-b988-15bfba1f95f9</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Binder1.pdf">https://portal.research.lu.se/files/3217945/1244547.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8324439</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>ATP</topic> <topic>LDCV</topic> <topic>Insulin</topic> <topic>exocytosis</topic> <topic>Compound Exocytosis</topic> <topic>Calcium</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-82-8</identifier> <identifier type="oldLupId">1244545</identifier> <part> <detail type="volume"> <number>2008:129</number> </detail> <extent unit="pages"> <total>101</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-30T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>b87bfbec-9a17-4048-b988-15bfba1f95f9</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:11:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:11:58+02:00</recordDateApproved> </recordInfo> </mods>

ApoM belongs to the lipocalin protein superfamily, and is found in all major lipoprotein classes, although the majority of apoM is found in high density lipoprotein, HDL.&lt;br/&gt;&lt;br&gt; In apoM, the signal peptide is retained in the mature protein. ApoM with a cleavable signal peptide was constructed. In contrast to wild-type protein, the size of apoM with a cleaved signal peptide corresponded to free, unassociated apoM, strongly indicating that the signal peptide is necessary for the protein´s ability to associate with lipoproteins.&lt;br/&gt;&lt;br&gt; To facilitate clinical studies, an ELISA for the measurement of apoM was developed and reference ranges established using samples from the NOBIDA biobank. Correlation studies of apoM with 26 common clinical chemical analytes was performed and a marked positive correlation was observed with plasma total cholesterol (r=0.52) and LDL and HDL cholesterol (r=0.43 and 0.36, respectively).&lt;br/&gt;&lt;br&gt; To investigate whether apoM levels predict the risk for coronary disease, apoM was measured in samples from CHD and control subjects drawn from two prospective case-control studies, FINRISK ´92 and the Copenhagen City Heart Study (255 and 1865 individuals in total, respectively). In conditional logistic regression analyses, apoM was not a predictor of CHD events.&lt;br/&gt;&lt;br&gt; Plasma apoM was investigated as a possible biomarker for MODY3 disease. Mean serum apoM was 5% lower in carriers of the P291fsinsC mutation of HNF-1a compared to family control subjects. The difference remained statistically significant after exclusion of diabetic individuals but is too small for apoM to be employed as a biomarker for HNF-1a mutation status. In a separate study, no significant difference in apoM concentration was observed between MODY3 and type 2 diabetic patients.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9bffe188-fe40-422a-87d1-92b892960963</url> </location> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>signal peptide</topic> <topic>Apolipoprotein</topic> <topic>signal peptidase</topic> <topic>ELISA</topic> <topic>MODY</topic> <topic>coronary heart disease</topic> </subject> <subject authority="lup"> <topic>Medicinal Chemistry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-12-5</identifier> <identifier type="oldLupId">1149773</identifier> <part> <detail type="volume"> <number>2008:59</number> </detail> <extent unit="pages"> <total>118</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-28T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>9bffe188-fe40-422a-87d1-92b892960963</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:00+02:00</recordDateApproved> </recordInfo> </mods>

Some paradoxes inherent in the concept and method of empowerment, however, lead to questioning the contradiction between freedom and force that is usually framed by “empowerment”. This dissertation investigates how empowerment is created in a concrete language and an integration project directed towards a group of women with refugee and immigrant background. The Project was part of the Equal Program under the European Social Fund. Departing from the paradoxes characterizing empowerment, the principal research questions of the dissertation are: How is empowerment created in the Project? What shall practices of empowerment create? The dissertation demonstrates that empowerment as the will to liberate, cannot be understood as a liberating method. Rather it has to be understood as a form of power aiming to create certain subjects corresponding to the objective of the making of empowerment. In other words, liberation cannot be derived from an essential meaning. The meaning of liberation receives a specific meaning from the institutional context within which it takes place and are being made. Based on the French philosopher Michel Foucault’s concept of power, I employ a perspective of power analysis, within which empowerment is perceived as a productive power, and the subjectivity of the individual is seen as an object of power. Empowerment becomes a way to govern to change and create subjects in accordance with its own objective. The analysis of empowerment hence turns into an investigation of empowerment as a form of productive power, and addresses the question of how empowerment is created, and what it itself creates. The Dissertation shows that the problematization of the women, which is the precondition for empowerment, is principally, based on culture. When the will to liberate is about liberation from a culture, the women are created as deviating from a Swedish norm. Empowerment frames the individual or the group in a specific way, whereby other conditions that can have importance for their situation as a marginalized group are foreclosed. The will to liberate in this way risks becoming an empowerment space that itself sustains the inequality from which it was intended to liberate.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/65e004c1-6b9a-4527-af20-fa9a5b186ccc</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Tabitha_Afhandling_Socialhogskolan.pdf">https://portal.research.lu.se/files/3221570/1365620.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">750586</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Socialhögskolan, Lunds universitet</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">dan</languageTerm> </language> <subject> <topic>Social Work</topic> <topic>Subjektivation</topic> <topic>Power</topic> <topic>Empowerment</topic> <topic>Normalization</topic> </subject> <subject authority="lup"> <topic>Social Work</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Dissertations in Social Work</title> </titleInfo> <identifier type="issn">1650-3872</identifier> <identifier type="isbn">978-91-89604-42-1</identifier> <identifier type="oldLupId">1365615</identifier> <part> <detail type="volume"> <number>35</number> </detail> <extent unit="pages"> <total>232</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-04-17T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>65e004c1-6b9a-4527-af20-fa9a5b186ccc</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:14+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:14+02:00</recordDateApproved> </recordInfo> </mods>

Today´s treatments mainly rely on daily insulin injections. This help people to control blood glucose levels but still many patients suffer from the many complications associated with diabetes. Transplantations of islet cells are an alternative treatment that could help patients to become insulin independent and presumably also delay the development of complications. However, the increasing number of diabetic patients would require large amounts of transplantable insulin producing cells. Due to the fact that islet donor material is a limiting factor for transplantations, human embryonic stem cells (hESCs) could be an alternative source of transplantable insulin producing cells. hESCs have the unique potential to self-renew and to differentiate to many cell types, presumably also beta cells. In order to generate therapeutically relevant beta cells, the scientific community focuses on recapitulating the embryonic processes behind beta cell development. In order to develop protocols that direct differentiation of hESCs along the developmental program of pancreas development, cellular markers and methods that allow the identification and isolation of cells that displays a correct phenotype of each developmental stage are fundamental research tools. Identification of definitive endoderm (DE) - from where pancreas originates, requires analysis methods that can detect multiple markers within individual cells, since many markers expressed in DE are also detected in extraembryonic endoderm. In this thesis, we approached single cell gene expression analysis of hESCs differentiated towards DE to provide insight about expression of a panel of DE markers at the cellular level. Some of these markers have conventionally been measured by gene expression analysis at the population level and little information is available about expression at the cellular level in differentiating hESCs. To differentiate hESCs towards DE three different methods of activin A treatment were used. Single-cell gene expression analysis identified distinct gene expression signatures both between the activinA treated populations and within each population. Within the SOX17+ population, the DE markers CER1 and FOXA2 were co-expressed in the majority cells independent of activin A treatment. By contrast, HHEX, CXCR4, FOXA2, MIXL1 and LIM1/LHX1 were expressed to various extents within the SOX17+ populations of each activin A treatment. These data provides novel insight in DE gene expression at the cellular level of vitro differentiated hESCs and illustrates the usefulness of single-cell gene expression analysis in to identify the molecular signature of in vitro differentiated hESCs. Thus, this technique could be of great help to develop protocols that mimics pancreas development in vivo. &lt;br/&gt;&lt;br&gt; Furthermore, this thesis includes work that test the ability of RA and FGF4 alone or in combination to direct differentiation of hESCs towards PDX1+ foregut endoderm. The rationale for this was that both RA and FGF signaling exhibit a patterning effect during endoderm patterning and also supports pancreas specification. By optimizing the timing and concentration of RA and FGF4, it was shown that RA is required to convert activin A-induced hESCs into PDX1+ cells and that part of the underlying mechanism involves FGF signaling. Characterization of the PDX1+ cells suggests that they represent posterior foregut endoderm not yet commited to pancreatic, posterior stomach or duodenal endoderm.&lt;br/&gt;&lt;br&gt; Directed differentiation of hESCs would greatly benefit from a deeper understanding of the molecular mechanism that regulate growth and differentiation. To approach these questions, efficient genetic engineering techniques are advantageous tools for controlled expression of genes or to introduce fluorescent reporter genes. Constitutive promoters are useful tools due to their high level of expression in most cell types. Different eukaryotic/mammalian and viral constitutive promoters have been reported to ensure high level and sustained activity in hESCs but a comprehensive study was lacking. In this thesis, we performed a comparative study the activity and stability of five commonly used promoters in undifferentiated hESCs and during differentiation. These data suggested ACTB, EF1α and PGK promoters as the most stable promoters during long term culture of undifferentiated hESCs. During EB differentiation, activities of all five promoters were downregulated and EF1α was the most stable promoter although it was downregulated in 50% of the cells. Gene expression analysis of differentiated cells indicated that promoter activities might be restricted to specific cell lineages, indicating the need to carefully select optimal promoters for constitutive gene expression in differentiated hESCs.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c652eba4-67ef-421c-8fc8-fc0d16bc9f2a</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Karin_Norrman.pdf">https://portal.research.lu.se/files/3221595/2064564.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1100666</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Stem Cells and Pancreas Developmental Biology, Dept of Laboratory Medicine</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>human embryonic stem cells</topic> <topic>diabetes</topic> <topic>pancreas</topic> <topic>definitive endoderm</topic> <topic>foregut endoderm</topic> <topic>pancreatic endoderm</topic> <topic>constitutive promoter</topic> <topic>ACTB</topic> <topic>EF1alpha</topic> <topic>CMV</topic> <topic>PGK</topic> <topic>UbC</topic> </subject> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-16-1</identifier> <identifier type="oldLupId">2064545</identifier> <part> <detail type="volume"> <number>2011:66</number> </detail> <extent unit="pages"> <total>123</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-09-20T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The prognosis is dismal and early diagnosis and treatment is of vital importance for the outcome. Clinical presentation is unspecific. The five studies were retrospective. The patients were retrieved from Malmö University Hospital. &lt;br/&gt;&lt;br&gt; The aim with this thesis was to illustrate a geriatric perspective in AIBD by comparing clinical presentation and roentgenological findings in older and in younger patients, and to describe changes in the incidence in relation to demographic data and autopsy frequency.&lt;br/&gt;&lt;br&gt; Results: One-hundred and thirty-five patients were identified with AIBD in Malmö 1987-1996. In 75 operations, 42 patients had bowel-resection. The prognosis was poor for the very old, whereas the less old have a much more favourable prognosis (p&amp;lt;0.001). The elderly had higher incidence of unresectable gangrene despite the same time course to operation as the younger (p&amp;lt;0.001). Delay in surgical intervention was associated to increasing mortality (p= 0.038), but no age differences were noted. &lt;br/&gt;&lt;br&gt; AIBD in the old was associated with a significantly different clinical presentation (confusion, hematemesis, vomiting and dehydration) and a higher mortality compared with younger patients (p=0.003). Digitalis treatment seems to be associated with increased mortality in ischemic bowel disease. Prodromal signs were prognostically unfavorable.&lt;br/&gt;&lt;br&gt; Eighty-nine patients were examined by abdominal plain film. Plain film findings differed with age. Bowel dilatation, which was associated to mortality, was more frequent in the elderly with AIBD (p&amp;lt;0.05), whereas gasless abdomen was more common in younger patients (p=0.001). &lt;br/&gt;&lt;br&gt; Between 2004-2008, 36 patients were examined with multi detector computed tomography with intravenous contrast (MDCTiv). Two out of three were correctly diagnosed by MDCTiv at first evaluation. At re-evaluation, SMA occlusion was found in all cases with MDCTiv, and intestinal findings were present in half. In-hospital mortality rate was 42% for patients who underwent MDCTiv, which was significantly lower compared to 90% for the 10 patients examined with plain MDCT (p=0.007), and 71% for patients not examined with MDCTiv or plain MDCT (p=0.031). &lt;br/&gt;&lt;br&gt; Between 2000–2006, the overall incidence rate of AIBD decreased from 8.6 to 5.4/100 000 person years compared to 1970 –1982, and the autopsy rate from 87% to 25% over time. The in-hospital mortality rate was 63% in the latter time period. For those being investigated with MDCTiv and undergoing vascular intervention the in-hospital mortality was 34% (9/25) and 20% (2/20), respectively. General and vascular surgeons collaborated in 25 out of 61 patients that underwent an intervention, of which 21 (84%) (p&amp;lt;0.001) survived. &lt;br/&gt;&lt;br&gt; Conclusions: Advanced age is a strong risk factor in surgery for AIBD, with higher incidence of unresectable gangrene despite the same time course from admission to operation as younger age groups. AIBD in the old is associated with a different clinical presentation and higher mortality compared to younger patients. Elderly with AIBD presented more frequent with colon dilatation with G/F-levels and small bowel dilatation in plain film, whereas younger patients presented with a gasless abdomen. Examination with MDCTiv in patients with acute SMA occlusion was associated with survival benefit. The overall mortality rate in patients with acute SMA occlusion remains high. A close collaboration between radiologists, general and vascular surgeons seems to be most important to lower the mortality in patients with acute SMA occlusion.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e8ac8ef5-1ced-4c51-b09d-6a483392eef3</url> </location> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>multislice CT</topic> <topic>abdominal plain film</topic> <topic>Ischemic bowel disease</topic> <topic>elderly</topic> <topic>epidemiology</topic> <topic>operations</topic> <topic>symptoms</topic> </subject> <subject authority="lup"> <topic>Gerontology, specialising in Medical and Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-94-86253-33-2</identifier> <identifier type="oldLupId">1389567</identifier> <part> <detail type="volume"> <number>2009:45</number> </detail> <extent unit="pages"> <total>136</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-15T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>e8ac8ef5-1ced-4c51-b09d-6a483392eef3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:20+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:20+02:00</recordDateApproved> </recordInfo> </mods>

Thus, the scope of the thesis does not lie on the medieval period with its rural settlements and their inhabitants, but rather on their archaeological historiography during the 20th and 21st centuries. Sweden (Fosie) serves as a point of departure and together with examples from Germany (Hohenrode), Denmark (Store Valby) and Great Britain (Wharram Percy) the over decades changing practices and approaches are discussed and analyzed.&lt;br/&gt;&lt;br&gt; Three conditions namely the technical, disciplinary and ideological constitute the theoretical foundations for the present study. In short, the technical conditions primarily relate to the fieldwork and the process of excavation at different times. The disciplinary conditions are defined as the study of those variables within the scientific sphere, and their internal relationship that have contributed to the formation of the field of medieval rural archaeology and its continued existence. In order to study these aspects the concept of boundary work has served as an inspiration. The ideological conditions focus on the interaction between archaeology and society, in my study mainly represented by discussions on the status of the medieval village in legislation.&lt;br/&gt;&lt;br&gt; Based on theoretical discussions and analyses made in the empirical studies, it is argued that the emergence, establishment and upcoming changes of medieval rural archaeology as a field of study are best distinguished by identifying different promoting and constraining factors. These conclusions are followed by discussing how best characterize and describe different subject areas. Based on observations made, the metaphor of a web consisting out of different spatial and temporal levels and nodes is proposed. This model serves as a complement to a more traditional chronological scheme and, thus, it contributes to a more complete and deeper understanding of the structure of scientific fields. The argument is also that the models application is versatile to other disciplines.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d624b51c-1a7e-462c-b6bb-0a5a2d86b5f4</url> </location> </relatedItem> <originInfo> <publisher>Department of Archaeology and Ancient History, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Wharram Percy</topic> <topic>medieval archaeology</topic> <topic>Fosie</topic> <topic>history of archaeology</topic> <topic>Store Valby</topic> <topic>medieval rural settlements</topic> <topic>Hohenrode</topic> <topic>Historical archaeology</topic> <topic>boundary work</topic> </subject> <subject authority="lup"> <topic>Archaeology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in Historical Archaeology</title> </titleInfo> <identifier type="issn">1653-1183</identifier> <identifier type="isbn">978-91-89578-21-X</identifier> <identifier type="oldLupId">1222759</identifier> <part> <detail type="volume"> <number>8</number> </detail> <extent unit="pages"> <total>309</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-03T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>d624b51c-1a7e-462c-b6bb-0a5a2d86b5f4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:30+02:00</recordDateApproved> </recordInfo> </mods>

Surgical resection of tumor mass in combination with radiotherapy and chemotherapy is only palliative and there is a clear need for new and more effective therapeutic strategies. &lt;br/&gt;&lt;br&gt; The aim of this study was to develop a dendritic cell (DC)-based vaccine for the treatment of experimental brain tumors with the future prospect of translating this treatment into the clinical application. We first demonstrated that the N29 and N32 rat brain tumors closely resemble human glioblastoma multiforme and anaplastic astrocytoma, respectively, and represent relevant models to study the efficacy of new therapeutic modalities. We also found that vaccination with IFN-γ-producing tumor cells led to tumor regression in a fraction of animals in both tumor models. The route of vaccine administration significantly influenced the outcome of the therapy. S.c. immunization with IFN-γ-producing tumor cells was far more effective compared to i.d. injection.&lt;br/&gt;&lt;br&gt; DCs generated from rat bone marrow progenitor cells exhibited the capacity to take up antigens in an immature state and induce T cell proliferation in a mature state, two functional properties central for the induction of anti-tumor immune response. We tested different antigen preparations and maturation factors in order to establish the optimal conditions for DC activation. Synergistic inhibition of intracerebral tumor growth was observed when rats were vaccinated with a combination of ex vivo tumor cell lysate-pulsed and matured DCs and IFN-γ-producing tumor cells. However, we did not observe any benefit of using DC-based vaccines alone regardless of antigen loading or maturation methods compared to immunotherapy with IFN-γ-producing tumor cells.&lt;br/&gt;&lt;br&gt; In conclusion, we have demonstrated that DC-based vaccines fail to provide protection in a weakly immunogenic brain tumor model but do enhance the anti-tumor immune responses elicited by IFN-γ-producing tumor cells. These findings could be pertinent to other tumor models and other immunotherapeutic modalities and thus have important implications for the development of anti-cancer vaccines.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/70734474-0103-4b18-99e6-8f589a0c5a5e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="janelidze_kappa.pdf">https://portal.research.lu.se/files/3228198/1149899.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5216608</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>dendritic cell</topic> <topic>interferon-γ</topic> <topic>immunotherapy</topic> <topic>Brain tumor</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-98-8</identifier> <identifier type="oldLupId">1059180</identifier> <part> <detail type="volume"> <number>2008:45</number> </detail> <extent unit="pages"> <total>107</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-09T13:00:00+02:00</dateOther> <note type="additionalInfo">This work was supported with grants from the Children’s Cancer Foundation of Sweden, the Gunnar Nilsson Foundation, the Skane region Funds and The Hans and Märit Rausing Charitable Foundation.</note> <recordInfo> <recordIdentifier>70734474-0103-4b18-99e6-8f589a0c5a5e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:30+02:00</recordDateApproved> </recordInfo> </mods>

It can also provide environmental benefits in terms of reduced fuel consumption. The effectiveness and reliability of these applications highly depends on the quality of the V2V communication link, which rely upon the properties of the propagation channel. Therefore, understanding the properties of the propagation channel becomes extremely important. This thesis aims to fill some gaps of knowledge in V2V channel research by addressing four different topics. The first topic is channel characterization of some important safety critical scenarios (papers I and II). Second, is the accuracy or validation study of existing channel models for these safety critical scenarios (papers III and IV). Third, is about channel modeling (paper V) and, the fourth topic is the impact of antenna placement on vehicles and the possible diversity gains. This thesis consists of an introduction and six papers:&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper I presents a double directional analysis of vehicular channels based on channel measurement data. Using SAGE, a high-resolution algorithm for parameter estimation, we estimate channel parameters to identify underlying propagation mechanisms. It is found that, single-bounce reflections from static objects are dominating propagation mechanisms in the absence of line-of-sight (LOS). Directional spread is observed to be high, which encourages the use of diversity-based methods.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper II presents results for V2V channel characterization based on channel measurements conducted for merging lanes on highway, and four-way street intersection scenarios. It is found that the merging lane scenario has the worst propagation condition due to lack of scatterers. Signal reception is possible only with the present LOS component given that the antenna has a good gain in the direction of LOS. Thus designing an antenna that has an omni-directional gain, or using multiple antennas that radiate towards different directions become more important for such safety critical scenarios.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper III presents the results of an accuracy study of a deterministic ray tracing channel model for vehicle-to-vehicle (V2V) communication, that is compared against channel measurement data. It is found that the results from measurement and simulation show a good agreement especially in LOS situations where as in NLOS situations the simulations are accurate as far as existing physical phenomena of wave propagation are captured by the implemented algorithm. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper IV presents the results of a validation study of a stochastic NLOS pathloss and fading model named VirtualSource11p for V2V communication in urban street intersections. The reference model is validated with the help of independent channel measurement data. It is found that the model is flexible and fits well to most of the measurements with a few exceptions, and we propose minor modifications to the model for increased accuracy.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper V presents a shadow fading model targeting system simulations based on channel measurements. The model parameters are extracted from measurement data, which is separated into three categories; line-of-sight (LOS), LOS obstructed by vehicles (OLOS), and LOS blocked by buildings (NLOS), with the help of video information recorded during the measurements. It is found that vehicles obstructing the LOS induce an additional attenuation in the received signal power. The results from system level vehicular ad hoc network (VANET) simulations are also presented, showing that the LOS obstruction affects the packet reception probability and this can not be ignored. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper VI investigates the impact of antenna placement based on channel measurements performed with four omni-directional antennas mounted on the roof, bumper, windscreen and left-side mirror of the transmitter and receiver cars. We use diversity combining methods to evaluate the performance differences for all possible single-input single-output (SIMO), multiple-input single-output (MISO) and multiple-input multiple-output (MIMO) link combinations. This investigation suggests that a pair of antennas with complementary properties, e.g., a roof mounted antenna together with a bumper antenna is a good solution for obtaining the best reception performance, in most of the propagation environments.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In summary, this thesis describes the channel behavior for safety-critical scenarios by statistical means and models it so that the system performance can be assessed in a realistic manner. In addition to that the influence of different antenna arrangements has also been studied to exploit the spatial diversity and to mitigate the shadowing effects. The presented work can thus enable more efficient design of future V2V communication systems.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2fc7c344-fc69-4133-ab96-6b7f42f107a6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Dissertation_TaimoorAbbas_Online.pdf">https://portal.research.lu.se/files/3228298/4251868.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">35522710</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Electrical and Information Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Vehicle-to-vehicle communications</topic> <topic>IEEE 802.11p</topic> <topic>Channel measurements</topic> <topic>Channel modeling</topic> <topic>propagation modeling</topic> <topic>MIMO</topic> <topic>intelligent transportation systems</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <location> <url>http://www.lth.se/english/research/publications_and_dissertations/dissertations/#1</url> </location> </relatedItem> <relatedItem type="host"> <titleInfo> <title>Series of licentiate and doctoral dissertations</title> </titleInfo> <identifier type="issn">1654-790X</identifier> <identifier type="isbn">978-91-7473-853-7 (pdf)</identifier> <identifier type="isbn">978-91-7473-852-0 (print)</identifier> <identifier type="oldLupId">4251789</identifier> <part> <extent unit="pages"> <total>215</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-02-24T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>2fc7c344-fc69-4133-ab96-6b7f42f107a6</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:31+02:00</recordDateApproved> </recordInfo> </mods>

There is no consensus in Danish neonatal intensive care units (NICUs) about which clinical methods facilitate breastfeeding. Skin-to-skin contact between infant and parent is the first step in the breastfeeding process for preterm infants, but studies of toleration &lt;br/&gt;&lt;br&gt; of skin-to-skin contact in extremely preterm infants – less than 28 gestational weeks – are sparse.&lt;br/&gt;&lt;br&gt; The overall aim of this thesis was to study and identify factors associated with breastfeeding of preterm infants, in infants, mothers and clinical practice in order to gain more knowledge of how to guide mothers of preterm infants in breastfeeding. This thesis is based on three studies: Study A, a clinical intervention study with 22 clinically stable extremely preterm infants that investigated infants’ tolerance of skin-to-skin contact with their parents; Study B, a national survey of breastfeeding support at all Danish NICUs; and Study C, a national prospective cohort study of breastfeeding preterm infants with the participation of 1,221 mothers and their 1,488 preterm infants at a gestational age of 24-36 weeks. Regression analyses were used to investigate factors associated with early establishment of exclusive breastfeeding, exclusive breastfeeding at discharge and adequate duration in accordance with the Danish Health and Medicines Authority’s recommendations.&lt;br/&gt;&lt;br&gt; The results showed that the extremely preterm infants in Study A, with mean weight 702 grams, tolerated skin-to-skin contact with their parents with no significant differences in mean skin temperature, heart rate, respiration rate, or oxygen saturation before, during, and after skin-to-skin contact. In Study B, the NICUs reported that they aimed for early skin-to-skin contact, and in 81% of the infants, skin-to-skin contact was initiated within the first 24 hours of life, but significantly fewer of the extremely preterm infants did so. In Study B, the NICUs described support of breastfeeding as being highly prioritised, reflected in skin-to-skin contact and parents’ presence at the NICU, recommendations of breast milk expression, supplementation feedings via feeding tubes, and avoidance of the use of infant feeding bottles as a common practice.&lt;br/&gt;&lt;br&gt; Of the 1,488 preterm infants in Study C, 99% initiated breastfeeding, at discharge, 68% were exclusively breastfed, 17% were partially breastfed, and 31% were exclusively breastfed for an adequate duration following discharge.&lt;br/&gt;&lt;br&gt; Factors in infants, mothers and clinical practice were associated with exclusive breastfeeding. Extremely preterm infants and multiples established exclusive breastfeeding at a higher postmenstrual age (PMA) and had twice the odds of not being exclusively breastfed at discharge. Mothers with low and intermediate education, with less breastfeeding experience, or who smoked had higher odds of inadequate duration of exclusive breastfeeding.&lt;br/&gt;&lt;br&gt; Admitting mothers to the NICU together with the infant immediately after delivery was associated with 1.5 (95% CI 0.3-2.6) days earlier establishment of exclusive breastfeeding. Initiation of breast milk expression showed a dose-response effect: the later the initiation, the higher the odds ratio (OR) for failure of exclusive breastfeeding at discharge and inadequate duration of exclusive breastfeeding. &lt;br/&gt;&lt;br&gt; Nipple shield use was associated with failure of exclusive breastfeeding at discharge (OR 2.3 (95% CI 1.6-3.2)) and inadequate duration of exclusive breastfeeding (OR 1.4 (95% CI 1.1-1.9)). Minimising the use of a pacifier during breastfeeding establishment was associated with 1.2 (95% CI 0.1-2.3) days earlier establishment of exclusive breastfeeding and showed a protective effect for exclusive breastfeeding at discharge (OR 0.4 (95% CI 0.3-0.6)). Test weighing the infant also showed a protective effect for exclusive breastfeeding at discharge (OR 0.6 (95% CI 0.4-0.8)).&lt;br/&gt;&lt;br&gt; Breastfeeding milestones were generally reached at different PMAs for various GA groups, but preterm infants were able to initiate breastfeeding early, with some delay in infants less than GA 32 weeks. &lt;br/&gt;&lt;br&gt; The results indicate that it is possible to establish early skin-to-skin contact with clinically stable extremely preterm infants. Danish preterm infants initiate breastfeeding to the same extent as full-term infants. Breastfeeding competence is not developed at a fixed postmenstrual age, but is influenced by multiple factors in infants, mothers and clinical practice. Admitting mothers to the NICU immediately after delivery seems to contribute to earlier establishment of exclusive breastfeeding. Minimising the use of pacifiers during breastfeeding establishment, restricting the use of nipple shields, encouraging early initiation of breast milk expression, and test weighing of infants may facilitate exclusive breastfeeding in preterm infants. &lt;br/&gt;&lt;br&gt; More support and attention should be given to groups with a higher risk for failure of exclusive breastfeeding: preterm infants with a gestational age of less than 32 weeks, multiples, mothers who smoke, have lower education or less breastfeeding experience.</abstract> <abstract lang="swe">&lt;b&gt;Abstract in Danish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Amning har sundhedsmæssige fordele for mor og barn og mere udtalte fordele for præmature børn, men udenlandske undersøgelser viser, at færre præmature børn påbegynder amning, og færre præmature børn ammes i 4 og 6 måneder sammenlignet med mature børn. Der findes ikke danske undersøgelser om andelen af præmature børn, som påbegynder amning, men en dansk undersøgelse viser, at 60 % af de præmature børn ammes fuldt ved udskrivelse til hjemmet. Der er ikke enighed mellem danske neonatalafdelinger eller international forskningslitteratur om, hvilken klinisk praksis der fremmer amning. Hud-mod-hud-kontakt mellem det præmature barn og forældrene er det første skridt i ammeetablering hos præmature børn, men undersøgelser af hud-mod-hud-kontakt med ekstremt præmature børn under 28 gestationsuger er sparsomme.&lt;br/&gt;&lt;br&gt; Afhandlingens overordnede formål var at identificere og undersøge faktorer der har sammenhæng med amning af præmature børn - både faktorer hos børn, mødre og i den kliniske praksis - for at danne mere viden og kunne vejlede mødre til præmature børn om amning på et evidensbaseret grundlag.&lt;br/&gt;&lt;br&gt; Afhandlingen består af tre undersøgelser. Studie A: et interventionsstudie om ekstremt præmature børn tolererer hud-mod-hud-kontakt med deres forældre med deltagelse af 22 stabile børn født før 28 gestationsuger, Studie B: en national spørgeskemaundersøgelse af ammeforhold på alle 19 danske neonatalafdelinger, og Studie C: en national spørgeskemaundersøgelse af amning af præmature børn med deltagelse af 1.221 mødre og deres 1.488 præmature børn med gestationsalder (GA) 24-36 uger. Vi undersøgte hvilke faktorer, der havde sammenhæng med tidlig etablering af fuld amning, fuld amning ved udskrivelse til hjemmet, og varigheden af fuld amning i henhold til Sundhedsstyrelsens anbefalinger.&lt;br/&gt;&lt;br&gt; De ekstremt præmature børn i Studie A havde på undersøgelsestidspunktet en gennemsnitlig postmenstruel alder (PMA) på 26 uger og 5 dage og en gennemsnitlig vægt på 702 gram. Børnene tolererede hud-mod-hud-kontakten med forældrene uden betydende forskelle i gennemsnitlig hudtemperatur, puls, respiration eller ilt-saturation før, under og efter hud-mod-hud-kontakten, hvilket betyder, at det er muligt at etablere tidlig hud-mod-hud-kontakt med stabile ekstremt præmature børn.&lt;br/&gt;&lt;br&gt; Neonatalafdelingerne beskrev, at de stræber efter tidlig etablering af hud-mod-hud-kontakt, og 81 % af de præmature børn påbegyndte dette indenfor det første levedøgn, men væsentlig færre af de ekstremt præmature børn. Neonatalafdelingerne beskrev at forholdene for amning generelt var gode afspejlet i hud-mod-hud-kontakt, forældres tilstedeværelse, anbefalinger for udmalkning, tilskud med sonde, og tilbageholdenhed med brug af sutteflasker.&lt;br/&gt;&lt;br&gt; Af de deltagende børn påbegyndte 99 % amning, ved udskrivelse var 68 % fuldt ammede og 17 % var delvist ammede, 31 % af børnene levede op til Sundhedsstyrelsens anbefaling om varigheden af fuld amning.&lt;br/&gt;&lt;br&gt; Faktorer hos børn, mødre og i klinisk praksis havde sammenhæng med amning af præmature børn. Ekstremt præmature børn samt tvillinger og trillinger, etablerede fuld amning senere (ved en højere PMA), og havde dobbelt så høj risiko for ikke at være ammet ved udskrivelse. Mødre med kort og mellemlang uddannelse, med kortere ammeerfaring, og mødre der røg havde større risiko for utilstrækkelig længde af fuld amning. Førstegangsfødende etablerede fuld amning halvanden dag senere end flergangsfødende. &lt;br/&gt;&lt;br&gt; Klinisk praksis havde også betydning. At medindlægge moderen på neonatalafdelingen direkte efter fødslen viste større mulighed for at etablere fuld amning nogle dage tidligere, 29 % af mødrene blev medindlagt direkte. Børn der anvendte suttebrik havde dobbelt så stor risiko for ikke at være ammet fuldt ved udskrivelse og halvanden gang så stor risiko for utilstrækkelig længde af fuld amning, men anvendelsen af suttebrik havde ikke indflydelse på, hvor tidligt børnene etablerede fuld amning. Børn, hvor brugen af narresut blev minimeret under ammeetableringen, etablerede amning en dag hurtigere, og havde dobbelt så stor chance for at være fuldt ammede ved udskrivelsen. Brug af kontrolvejning, dvs. at veje barnet lige før og efter en amning, viste halvanden gang større chance for at være fuldt ammet ved udskrivelsen, men havde ingen sammenhæng med hvor tidligt eller hvor længe barnet blev fuldt ammet. Der var stor forskel mellem neonatalafdelingerne på, hvor mange børn der havde anvendt suttebrik, narresut og kontrolvejning under indlæggelsen.&lt;br/&gt;&lt;br&gt; Hvor tidligt moderen påbegyndte udmalkning af modermælk viste en dosis-responseffekt på fuld amning ved udskrivelse og anbefalet varighed af fuld amning, jo tidligere, jo mere positivt for amning, men ikke alle resultater havde statistisk styrke. Mødre, der påbegyndte udmalkning senere end 48 timer efter fødslen, havde fem gange forhøjet risiko for ikke at amme fuldt ved udskrivelse, og mødre der påbegyndte udmalkning mellem 12 og 24 timer efter fødslen havde halvanden gang større risiko for utilstrækkelig længde af fuld amning. Dosis-responseffekten tillader dog at anbefale, at udmalkning påbegyndes tidligt efter fødslen.&lt;br/&gt;&lt;br&gt; Vi kan konkludere, at stabile ekstremt præmature børn tolererer hud-mod-hud-kontakt med deres forældre. Danske præmature børn påbegynder amning i samme grad som mature børn. &lt;br/&gt;&lt;br&gt; Præmature børns ammekompetencer bliver ikke udviklet ved en fast alder, men har sammenhæng med forhold hos børn, mødre og i klinisk praksis. At medindlægge mødrene på neonatalafdelingen direkte efter fødslen, kan formentlig medvirke til tidligere etablering af fuld amning. Det ser ud til, at minimering af brug af narresut under ammeetableringen, begrænsning i brug af suttebrikker, påbegyndelse af udmalkning tidligst muligt efter fødslen og anvendelse af kontrolvejning fremmer amning af præmature børn. Der savnes dog forskning i, hvordan mødre støttes, når kontrolvejning stoppes ved barnets udskrivelse, da disse mødre hurtigere holder op med at amme fuldt.&lt;br/&gt;&lt;br&gt; Ekstra støtte og opmærksomhed bør gives til grupper med større risiko for ikke at amme fuldt, dvs. de ekstremt og meget præmature børn, tvillinger/trillinger, mødre der ryger, har kortere uddannelse eller kortere ammeerfaring.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; The overall aim of the thesis was to study and identify factors associated with breastfeeding of preterm infants in the infant, the mother and clinical practice.

The survey showed that Danish NICUs described the support of breastfeeding as a high priority, as reflected in skin-to-skin contact and parental presence at the NICU, practice of breast milk pumping and supplementation via feeding tubes, and avoidance of the use of infant feeding bottles as a common practice.

In colorectal cancer cell lines, anaphase bridging was observed to generate both numerical and structural chromosomal aberrations and was also associated with the presence of multipolar mitoses. In contrast to cells having undergone anaphase bridging, daughter cells from these multipolar mitotic figures were observed not to form clones in culture, possibly because of the severe aneuploidy which is the result of multipolar mitosis. Chromosomal instability was observed also in colorectal cancer cell lines with mutations in the mismatch repair genes. In Wilms tumour, chromosomal instability was found to be associated with an aggressive tumour phenotype and poor survival. Telomere shortening was more pronounced in the immature tumour components, which could explain the fact that anaphase bridges and multipolar mitoses were only observed in these tumour elements. Because of breakage-fusion-bridge cycles, chromosomal instability is associated with karyotypes with extensive structural chromosomal rearrangements. By applying a combination of subtelomeric FISH, G-banding and multicolour FISH, a high resolution for cytogenetic analysis of tumours with chromosomal instability could be obtained. This combined approached was used also to search for reciprocal translocations leading to fusion genes in Wilms tumour. Although the technique proved efficient, no recurrent reciprocal translocation was found in Wilms tumour. Our results indicate that telomere dependent chromosomal instability is present in both colorectal cancer and Wilms tumour and could be an important prognostic factor in Wilms tumours.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/aa25f70d-eeff-4b07-b685-79500a554219</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis_080117l.pdf">https://portal.research.lu.se/files/3231749/1022288.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">495868</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Divison of Clinical Genetics</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>structural rearrangement</topic> <topic>Ewing family tumour</topic> <topic>Chromosomal instability</topic> <topic>nephroblastoma</topic> <topic>Wilms tumour</topic> <topic>chromosomal aberration</topic> <topic>anaphase bridge</topic> <topic>subtelomeric FISH</topic> <topic>breakage-fusion-bridge cycle</topic> </subject> <subject authority="lup"> <topic>Medical Genetics and Genomics (including Gene Therapy)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-63-6</identifier> <identifier type="oldLupId">1022212</identifier> <part> <detail type="volume"> <number>2008:10</number> </detail> <extent unit="pages"> <total>88</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-02-29T10:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>aa25f70d-eeff-4b07-b685-79500a554219</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:45+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:45+02:00</recordDateApproved> </recordInfo> </mods>

Bipedal stance is learned during childhood and constantly adapted to changing circumstances throughout life. Failure to attain and maintain the control of upright posture can have catastrophic consequences. Postural competence needs to be recovered in a multitude of illness, in developmental disorders as well as to age related decreasing function. To meet this end, health professionals utilise a multitude of techniques, mainly based on sensory based training exercises. &lt;br/&gt;&lt;br&gt; The overall ambition of this thesis was to enhance knowledge on adaptive behaviour and motor learning of human postural control with the aim to identify new therapeutic concepts for training and rehabilitation. &lt;br/&gt;&lt;br&gt; The results demonstrate that postural control learning follow the general paradigm for memory formation, i.e. short-term learning is consolidated to long-term learning through central neural processes during inactivity. Long-term postural learning benefits from training with intervals more than three hours. Postural learning to withstand somatosensory or vestibular perturbations seems to follow different time schedules. Experiences from different postural tasks, if they post different demands, can be transferred to each other. Strategies to withstand postural perturbations include sensory reweighting (i.e. change of the relative importance of the individual sensory systems), and modifications and building of internal models (automatic postural programs). Children (7-9 years of age) had a more efficient consolidation of experiences from postural perturbations then adults. This could possibly be due to neural plasticity or a behaviour of ‘exploratory learning’. Patients suffering from Phobic Postural Vertigo – an anxiety related disorder, were shown to have an impaired adaptation, possibly due to an anxious control of posture which disable the patients to adapt their postural responses. This knowledge led to the development of a new therapeutic concept of ‘PREHAB’ prior to a sensory lesion which was implemented and studied. Patients scheduled for schwannoma surgery pre-treated with gentamicin, in order to produce a gradual sensory deafferentation, performed markedly better on the 6-month follow-up after surgery. Both compaired to before surgery and to other groups not treated with gentamicin and ‘PREHAB’. The effect could be attributed either to a sensory training concomitant with gradual sensory decline or to a separation in time of surgical and sensory trauma, or both in concert.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The findings elucidate several important aspects to be taken into account both for rehabilitation of patients as well as for designing future studies on postural control.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/076f21fc-70c8-47b9-ae18-4fb07f7761a7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Adaptation_and_learning_in_postural_control.pdf">https://portal.research.lu.se/files/3233404/1466033.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1259116</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Otorhinolaryngology, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Postural control</topic> <topic>Adaptation</topic> <topic>Learning</topic> <topic>Sensory reweighting</topic> </subject> <subject authority="lup"> <topic>Oto-rhino-laryngology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-61-5</identifier> <identifier type="oldLupId">1466032</identifier> <part> <detail type="volume"> <number>2009:73</number> </detail> <extent unit="pages"> <total>144</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-09-04T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>076f21fc-70c8-47b9-ae18-4fb07f7761a7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:55+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:55+02:00</recordDateApproved> </recordInfo> </mods>

These cases frequently had a history of wound complication after the primary arthroplasty. Acute haematogenous infection accounted for 22% and was more common in rheumatoid than in osteoarthritic patients.&lt;br/&gt;&lt;br&gt; The most common pathogen in cases infected within 2 years from the primary arthroplasty was coagulase-negative staphylococcus (CNS) and in acute haematogenous infections it was Staphylococcus aureus. Only 1 case of methicillin resistant S. aureus (MRSA) was found, while resistance to methicillin was common in CNS and increased during the study period.&lt;br/&gt;&lt;br&gt; Two-stage revision arthroplasty was performed in 60% and one-stage in 9%. Almost 30% were treated with poorer functional alternatives, i.e. arthrodesis, extraction of the implant, or above-the-knee amputation.&lt;br/&gt;&lt;br&gt; After a two-stage revision arthroplasty, only half of those with failure to eradicate infection were re-revised, the cumulative re-revision rate at 2 years being 9.4% and the cumulative rate of failure to eradicate infection being 17.8%. The only factor that predicted failure to eradicate infection after a one- and two-stage revision arthroplasty was a history of wound complication after the primary operation.&lt;br/&gt;&lt;br&gt; In a separate study the timing of administration of the first dose of perioperative antibiotic prophylaxis was studied and was found to be suboptimal in 55% of the 114 cases studied at Lund University Hospital, and in 47% of 198 cases randomly selected from the SKAR. &lt;br/&gt;&lt;br&gt; Awareness of the fact that most infections arise early, are associated with wound complications, and often caused by CNS should encourage use of judicious postoperative care to allow early diagnosis and adequate treatment. To improve the results of revision surgery it is recommended that the treatment is centralised to units where specialists in orthopaedics and infectious diseases are working in a team.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Vid en knäprotesoperation ersätts ledytorna i knäet med en protes gjord av metall och plast. Den vanligaste orsaken till denna operation är artros(ledsvikt. Antalet knäprotesoperationer ökar stadigt och 2009 utfördes 12,700 förstagångsoperationer i Sverige. Resultaten är överlag goda men en allvarlig komplikation som drabbar mellan 1 och 2% av patienterna är bakterieinfektion i leden. Om infektionen upptäcks tidigt kan den behandlas med upprensning i leden och antibiotika men annars måste protesen&lt;br/&gt;&lt;br&gt; avlägsnas. En ny protes kan sedan sättas in, antingen vid samma operation (en-stegsrevision) eller efter en protesfri period då patienten behandlats med antibiotika(två-stegsrevision). I vissa fall leder behandling av infektionen till steloperation och enstaka gånger till slinkled (led utan protes) eller amputation. Sedan 1975 har Svenska Knäprotesregistret (SKAR)&lt;br/&gt;&lt;br&gt; samlat information om knäprotesoperationer utförda i Sverige och denna databas har använts för att i detalj granska 478 fall som under åren 1986 till 2000 genomgick en knäprotesrevision på grund av infektion. En revision är en omoperation där protesdelar insättes, bytes eller borttages.&lt;br/&gt;&lt;br&gt; Studien visade att i 30% av fallen hade infektionen bekräftats inom 3 månader från primäroperationen och att två tredjedelar av infektionerna&lt;br/&gt;&lt;br&gt; hade bekräftats inom 2 år. Sårproblem efter primär operationen var vanligt förekommande bland dessa patienter. För att upptäcka infektioner tidigt är&lt;br/&gt;&lt;br&gt; noggrann uppföljning under den första tiden efter operation viktig och infektion måste misstänkas i de fall där sårproblem föreligger. Drygt 20% av infektionerna uppstod efter att bakterier tagit sig via blodbanan till leden. Denna typ av infektion (hematogen infektion) var vanligare hos patienter med ledgångsreumatism än hos de med ledsvikt.&lt;br/&gt;&lt;br&gt; Infektionerna orsakades oftast av stafylokocker, som är bakterier som normalt finns på huden. Under de första åren som studerades var Stafylococcus aureus (den gula stafylokocken) vanligast, medan koagulas-negativa stafylokocker (KNS, den vita stafylokocken) orsakade flest infektioner under de senare åren. I enbart 1 fall orsakades infektionen av meticillinresistent stafylococcus aureus (MRSA). Resistens bland KNS mot meticillin ökade under studietiden och närmare undersökningar behövs för att ta reda på hur vanligt det är att patienter inför knäprotesoperation bär på meticillinresistenta KNS. Bland KNS var resistens mot gentamicin, vilket är det antibiotikum som blandas i bencement för att minska risken för infektion, också vanlig och det måste ortopeder ta hänsyn till vid revisioner utförda på grund av infektion.&lt;br/&gt;&lt;br&gt; Den vanligaste behandlingsmetoden var två-stegsrevision (60%) och ytterligare 9% fick en ny knäled genom en-stegsrevision. Nästan 30% behandlades med steloperation, slinkled eller amputation. Det var regionala skillnader i val av behandling och de flesta ortopedkliniker behandlade mycket få fall. Det föreslås att knäprotesrevisioner på grund av&lt;br/&gt;&lt;br&gt; infektion centraliseras till enheter där ortopeder och infektionsläkare tillsammans styr behandlingen.&lt;br/&gt;&lt;br&gt; Två år efter två-stegsrevisionen hade 17.8% misslyckats med att bli av med infektionen. Vid denna tidpunkt hade 9.4% reviderats ytterligare en gång på grund av infektion (räknat med Kaplan-Meiers metod). Dessa resultat motsvarar de sämsta resultaten som har presenterats tidigare, men jämförelse försvåras av att tidigare studier ofta kommer från högspecialiserade enheter. Den enda faktorn som uppvisade ett samband med senare misslyckande i att bota infektion var förekomsten av sårproblem&lt;br/&gt;&lt;br&gt; efter primäroperationen. Detta understryker ytterligare vikten av ett adekvat omhändertagande av patienter med sårproblem.&lt;br/&gt;&lt;br&gt; I en separat studie granskades vid vilken tidpunkt den första dosen av förebyggande antibiotikum gavs. För att uppnå den bästa effekten av antibiotika rekommenderas att första dosen ges inom 45 till 15 minuter före operationsstart. Bland patienter opererade på Universitetssjukhuset i Lund fick 55% den första dosen utanför denna tidsrymd. Bland ett slumpmässigt urval patienter som registrerats i SKAR i samband med en knäprotesoperation fick 47% den första dosen antibiotikum utanför denna&lt;br/&gt;&lt;br&gt; tidsrymd. Användning av en checklista, framtagen av världshälsoorganisationen WHO, kan medföra en förbättring och rekommenderas.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9933c4e1-291d-4ebe-840c-69302b36cf6d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="AS_Kappa.pdf">https://portal.research.lu.se/files/3233640/1716562.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2495245</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>outcome</topic> <topic>revision knee arthroplasty</topic> <topic>microbiology</topic> <topic>Primary knee arthroplasty</topic> <topic>infection</topic> <topic>predictive factors</topic> <topic>antibiotic prophylaxis</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-31-0</identifier> <identifier type="oldLupId">1716561</identifier> <part> <detail type="volume"> <number>2010:115</number> </detail> <extent unit="pages"> <total>73</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-12-09T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>9933c4e1-291d-4ebe-840c-69302b36cf6d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:12:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:05:11Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:12:58+02:00</recordDateApproved> </recordInfo> </mods>

In the biofilm bacteria are protected against hostile environments. Biofilms are important clinically because of their persistence despite host defence and their recalcitrance to antimicrobials.&lt;br/&gt;&lt;br&gt; This thesis presents three main findings: (i) biofilm formation is an important virulence trait for opportunistic pathogens; (ii) combining different antibiotics may successfully cure device-related infections with biofilm-producing bacteria; (iii) mature biofilm is highly resistant to antibiotics. &lt;br/&gt;&lt;br&gt; First, we observed that the opportunistic pathogen Propionibacterium acnes, when isolated from deep infections, produced more biofilm in a microtitre model of biofilm formation, than superficical P.acnes isolates. The serotype distribution of P.acnes, determined by sequencing of recA, was similar among isolates from skin and deep infections, demonstrating that P.acnes isolates with different genetic backgrounds have pathogenic potential.&lt;br/&gt;&lt;br&gt; Furthermore, we observed that Enterococcus faecalis and Enterococcus faecium biofilms in vitro were susceptible to antibiotic combinations including rifampicin. Resistance to rifampicin was detected early if this agent was used as monotherapy, whereas combining it with some other specific antibiotics counteracted the development of rifampicin resistance.&lt;br/&gt;&lt;br&gt; Finally, we demonstrated that mature biofilm of enterococci in vitro is much more tolerant to antibiotics compared to new biofilm of the same species.&lt;br/&gt;&lt;br&gt; In conclusion, this thesis provides in vitro data stressing the importance of understanding the properties of bacterial biofilm in order to achieve successful antibiotic treatment of device related infections.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Vår hud och våra slemhinnor är ständigt koloniserade med bakterier som lever i fredligt samspel med vår organism. Dessa bakterier tillhör vår normalflora och kan indelas i kommensaler respektive opportunistiska bakterier. Kommensalerna gagnar värden på olika sätt och orsakar inte sjukdom, till skillnad från opportunisterna som under vissa betingelser kan orsaka infektion. Ibland rubbas samspelet av olika faktorer som påverkar värden, såsom vid skador, eller annan sjukdom. De opportunistiska bakterierna kan då, i samband med att immunförsvaret sviktar, ta sig till annars bakteriefria platser i kroppen.&lt;br/&gt;&lt;br&gt; De opportunistiska bakterierna kan bilda biofilm på främmande material i kroppen och blir därigenom svåråtkomliga för immunförsvaret. I biofilmen är bakterierna i ett speciellt metabolt tillstånd och inbäddade i ett skyddande matrix. Eftersom antibiotika har svårt att avdöda bakterier i biofilm så krävs ofta mycket långa behandlingstider och ovanliga antibiotikakombinationer. Ofta är dock antibiotikabehandling otillräcklig varför kirurgiskt avlägsnande av det främmande materialet fodras vilket får stora konsekvenser för patienten om infektionen har drabbat t ex en led- eller hjärtklaff protes. Biofilmsassocierade infektioner har blivit vanligare eftersom främmande material i form av katetrar, elektroder och proteser introduceras i kroppen i allt större utsträckning. Vidare lever fler patienter med nedsatt försvarsförmåga allt längre, vilket gör att opportunistiska bakterier oftare kommer att orsaka sjukdom.&lt;br/&gt;&lt;br&gt; Bakteriers ökade motståndskraft mot antibiotika har rönt stor uppmärksamhet de senaste åren och resistenta bakterier utgör ett enormt kliniskt problem i många länder. Få nya antibiotika är under utveckling och även i Sverige ökar resistensen på ett oroväckande sätt bland stafylokocker, enterokocker och andra tarmbakterier. De resistenta bakterierna finns framförallt på sjukhus i de miljöer där de mest infektionskänsliga patienterna vistas. Dessa patienter har dessutom ofta främmande material i kroppen och det är i stor utsträckning här som de opportunistiska bakterierna orsakar biofilmsrelaterade infektioner. Biofilmsbildande opportunistiska bakterier såsom enterokocker är generellt motståndskraftiga mot antibiotika och eftersom bakterierna i biofilm är än mer motståndskraftiga så skulle nya strategier för diagnostik och behandling vara av mycket stort värde.&lt;br/&gt;&lt;br&gt; Den här avhandlingen innehåller fyra arbeten om de opportunistiska bakterierna Propionibacterium acnes, Enterococcus faecalis och Enterococcus faecium, vilka alla kan bilda biofilm, har mer eller mindre besvärliga antibiotika resistensmönster och kan orsaka främmande kroppsinfektioner i t ex ledproteser.&lt;br/&gt;&lt;br&gt; Arbete 1 Protesinfektioner är ibland komplicerade att diagnosticera, delvis på grund av otillräckliga mikrobiologiska metoder som gör det svårt att säkerställa bakterie förekomst. På 90-talet gjordes en studie 192 där mer specifik diagnostik användes och denna visade att en stor del av protesinfektionerna med oklar bakteriegenes var orsakade av P.acnes. Detta var förvånande då P.acnes länge hade betraktats som en relativt harmlös hudbakterie. Studien inspirerade till arbete 1 som visar att P.acnes från djupa ledprotesinfektioner bildar betydligt mer biofilm än P.acnes bakterier från friska personers hud. Biofilmsbildning verkar alltså vara avgörande för P.acnes sjukdomsframkallande förmåga. Vi bestämde även de olika bakterieisolatens serotyper och undersökte om serotyp och biofilmsbildande förmåga gick att korrelera, samt om en viss serotyp oftare återfanns på huden eller i den djupa infektionen. Vi kunde inte påvisa ett samband, utan återfann olika serotyper i alla grupper. Då vi exponerade P.acnes för blodplasma minskade biofilmsbildningen, vilket stämmer med att P.acnes företrädelsevis ger upphov till främmande kroppsinfektioner på mindre blod genomströmmade lokaler såsom i neurokirurgiska shuntar, ortopediska proteser och i bröstimplantat.&lt;br/&gt;&lt;br&gt; Arbete II behandlar enterococcer som likt P.acnes är en grupp bakterier som tidigare betraktats som harmlösa men som under de senaste tre decennierna har avancerat till en tredje plats bland de mest förekommande sjukhusbakteriena i USA. Enterococcus faecalis och framförallt Enterococcus faecium uppvisar bådar uttalad antbiotikaresistens, stabil biofilmsproduktion, och benägenhet att både förvärva samt dela med sig av nya resistensmekanismer. Tack vare sin biofilmsbildande förmåga blir enterococcer än mer toleranta mot antibiotika. Då få nya antibiotika finns att tillgå var möjligheten att kombinera olika antibiotika som har olika verkningsmekanismer tilltalande. Antibiotika toleransen i en biofilm kan vara 1000 gånger högre jämfört med den i fritt flytande bakterier vilket innebär att det krävs högre antibiotika doser och längre behandlingstider vid biofilmsrelaterade infektioner. Vi visade att E.faecalis producerar robust biofilm som var känslig för kombinationsbehandling med ciprofloxacin och rifampicin eller med linezolid och rifampicin. &lt;br/&gt;&lt;br&gt; I Arbete III visades att behandling med de nya antibiotikatyperna tigecycline, daptomycin och linezolid i kombination med rifampicin hade effekt på E. faecium i biofilm. I både arbete II och III påvisade vi att uttalad rifampicin resistens utvecklas snabbt (inom 72timmar) om rifampicin används som enda preparat vid behandling av biofilm som bildats av enterococcer. &lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar studierna II och III på olika antibiotikakombinationer som har effekt i E.faecalis och E.faecium biofilm in vitro. Det är viktigt att påpeka att resultat från in vitro studier utförda i ”provrör” inte direkt kan appliceras på behandlingssituationer in vivo d v s studier gjorda på djur eller människor men det kan ge en fingervisning om vilka preparat som kan ha potential för vidare utvärdering i främmande kropps relaterade infektioner. &lt;br/&gt;&lt;br&gt; I Arbete IV undersöktes om skillnad i antibiotika känslighet i ny (24timmars) jämfört med gammal (120 timmars) biofilm kunde påvisas. I arbete II och III hade vi demonstrerat effekt av ciprofloxacin, linezolid, daptomycin, och tigecycline i kombination med rifampicin i ny enterococcus biofilm, varför vi använde samma preparat men utsatte den äldrer biofilmen för antibiotika under 24 timmar istället för 8 timmar. Åldrad biofilm visade sig vara mycket motståndskraftig mot alla antibiotika oavsett kombinationer och exponeringstid. Sammanfattningsvis är en åldrad enterococcus biofilm höggradigt resistent mot antibiotika. I den kliniska situationen torde därför tiden från infektionsstart till diagnos och behandling vara av stor betydelse.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d6ec1ba7-e7c6-4799-883f-0c7a7f194bd2</url> </location> </relatedItem> <originInfo> <publisher>Anna Holmberg</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Biofilm</topic> <topic>antibiotic susceptibility</topic> <topic>prosthetic joint infection</topic> <topic>MBEC</topic> <topic>Enterococcus faecalis</topic> <topic>Enterococcus faecium</topic> <topic>Propionibacterium acnes.</topic> </subject> <subject authority="lup"> <topic>Infectious Medicine</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">4075405</identifier> <part> <extent unit="pages"> <total>134</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-09-20T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>d6ec1ba7-e7c6-4799-883f-0c7a7f194bd2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:00+02:00</recordDateApproved> </recordInfo> </mods>

They prove quite successful&lt;br/&gt;&lt;br&gt; in modeling (temporal) dependence structures and go beyond the limitation of Gaussian models, thus allowing for heavy tails and skewness.&lt;br/&gt;&lt;br&gt; By generalizing the construction of the above class of models, it is possible to ‘control’ some random geometric features of the sample path&lt;br/&gt;&lt;br&gt; – while keeping the covariance function unaltered. Features such as&lt;br/&gt;&lt;br&gt; horizontal and vertical asymmetries (including the question of ‘time-&lt;br/&gt;&lt;br&gt; reversibility’ in financial context) and tilting of trajectories. These properties are most prominent in the extremes of the process (but do not exist&lt;br/&gt;&lt;br&gt; in e.g. Gaussian models) as shown by means of Rice’s formula for level&lt;br/&gt;&lt;br&gt; crossings. Different measures for assessing asymmetries in data records&lt;br/&gt;&lt;br&gt; are proposed and model fitting procedures discussed.&lt;br/&gt;&lt;br&gt; To combine stochastic and deterministic modeling in the context of numerical weather prediction, we present randomized versions of ‘simple’&lt;br/&gt;&lt;br&gt; physical models based on the shallow water equations. By embedding&lt;br/&gt;&lt;br&gt; deterministic shallow water motion into a Gaussian tempo-spatial convolution model, one obtains a velocity field that can be interpreted as&lt;br/&gt;&lt;br&gt; stochastically distorted shallow water flow. The methodology is meant&lt;br/&gt;&lt;br&gt; to provide prediction, estimation and the handling of uncertainties on&lt;br/&gt;&lt;br&gt; various scales.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d9eb581c-d72f-44ea-85e8-e32aa136b738</url> </location> </relatedItem> <originInfo> <publisher>Mathematical Statistics, Centre for Mathematical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>generalized Laplace</topic> <topic>shallow water equations</topic> <topic>asymmetry</topic> <topic>noise convolution models</topic> <topic>tempo-spatial fields</topic> <topic>non-Gaussian model</topic> </subject> <subject authority="lup"> <topic>Probability Theory and Statistics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Doctoral Theses in Mathematical Sciences</title> </titleInfo> <identifier type="issn">1404-0034</identifier> <identifier type="oldLupId">1691468</identifier> <part> <detail type="volume"> <number>2010:8</number> </detail> <extent unit="pages"> <total>141</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-11-12T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>d9eb581c-d72f-44ea-85e8-e32aa136b738</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:02+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:02+02:00</recordDateApproved> </recordInfo> </mods>

The use of&lt;br/&gt;&lt;br&gt; tobacco, alcohol, and illegal drugs in adolescence and young adulthood are well-known risk factors for subsequent substance-related harms. A better understanding of adolescent and young adult substance use behaviors and their correlates might help develop new prevention programs. This thesis aims to explore patterns of use and important risk factors for substance use among Swedish adolescents and adults.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Materials and methods: The papers in this thesis are based on three data sets. The first is from a survey on&lt;br/&gt;&lt;br&gt; substance use habits in the Swedish general population, answered by 22,095 individuals in the ages 15-64. The&lt;br/&gt;&lt;br&gt; second data set comes from a cohort of 1,398 adolescents and their parents, followed during the course of junior high school. The third data set is a cross-sectional online survey of 1,916 Swedish and Danish young adults in the ages 18-30. The study participants were asked about current substance use habits, and retrospective reports on adolescent risk behaviors.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Results: The first paper shows that adult cannabis users use other substances more compared to non-users.&lt;br/&gt;&lt;br&gt; Frequent cannabis users were more likely to use illicit drugs, but reported much lower levels of hazardous alcohol use. In the second paper, it was found that the parents of Swedish adolescents were largely unaware of their children&apos;s substance use behaviors. In the third study, we found that parental substance use and provision of alcohol were more influential on the adolescents&apos; substance use than parenting styles. In the fourth study, the&lt;br/&gt;&lt;br&gt; importance of adolescent risk behaviors for subsequent patterns of substance use in young adulthood was&lt;br/&gt;&lt;br&gt; confirmed.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Conclusions: Parents typically know little about their children&apos;s substance use, and the influence of parents&lt;br/&gt;&lt;br&gt; regarding adolescent substance use is limited. However, providing the children with alcohol is a common&lt;br/&gt;&lt;br&gt; parenting practice that is associated with increased substance use in adolescence. Lastly, there is a need for further research on different groups of cannabis users that may have different needs for prevention and intervention efforts.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d4391b21-c4cf-4a63-8667-5e44782adaa5</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_Jonas_Berge_151120.pdf">https://portal.research.lu.se/files/3234102/8228434.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5360882</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Substance use</topic> <topic>Alcohol</topic> <topic>Tobacco</topic> <topic>Cannabis</topic> <topic>Illicit drugs</topic> <topic>Adolescents</topic> <topic>Young adults</topic> </subject> <subject authority="lup"> <topic>Drug Abuse and Addiction</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-212-2</identifier> <identifier type="oldLupId">8228425</identifier> <part> <detail type="volume"> <number>2015:132</number> </detail> <extent unit="pages"> <total>105</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-12-11T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>d4391b21-c4cf-4a63-8667-5e44782adaa5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:08+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:08+02:00</recordDateApproved> </recordInfo> </mods>

In spite of effective medical treatment for acute HF, better pharmacological treatment for specific neurohormonal intervention and better diagnostic tools, e.g. biomarkers of natriuretic peptides, the morbidity and mortality due to this disease are still prominent. HF leads to vascular dysfunction in the general circulation but the interpretation of this is not clear. In our studies we have focussed on defining endothelial and smooth muscle dysfunction in the microvasculature of HF patients and correlating this dysfunction with the disease state.&lt;br/&gt;&lt;br&gt; This thesis addresses studies of elderly patients with varying degrees of HF. We determined blood levels of homocysteine and the natriuretic peptide precursor, NT-proBNP which is released by the failing heart. We also investigated vasoreactive response of the cutaneous microcirculation to different stimuli using a non-invasive iontophoresis-Laser Doppler probe method.&lt;br/&gt;&lt;br&gt; Paper I: We investigated the prognostic value of NT-proBNP for monitoring progression of HF. High blood levels (&amp;gt;5000) were found to indicate a poor prognosis of HF.&lt;br/&gt;&lt;br&gt; Paper II: An open study,- in which we evaluated the function of the cutaneous peripheral circulation of patients with chronic HF. We found that vasoreactivity declines with increasing age and HF. &lt;br/&gt;&lt;br&gt; Paper III: We evaluated vasoreactive responses in HF patients with homocysteinemi, before and 6 weeks after supplementary by B vitamin treatment. Homocysteine levels where then normalized and the cutaneous responses improved.&lt;br/&gt;&lt;br&gt; Paper IV: A controlled study in which, we investigated the microcirculation in chronic HF patients with different degrees of HF. We saw that the degree of severity of congestive HF did not correlate with decrease in vasoreactive responses. &lt;br/&gt;&lt;br&gt; Paper V: The effect of BNP in the microcirculation was studied in patients with severe congestive HF and compared to healthy, matched controls. The result shows that BNP has a significantly weaker vasodilation in HF patients and this is probably due to down regulation at the receptor-coupling level.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Forskningen har visat &lt;br/&gt;&lt;br&gt; Den ökade prevalensen av kronisk hjärtsvikt utgör en enorm utmaning för sjukvården. Trots att vi idag har effektiva medicinska behandlingar vid hjärtsvikt och bra läkemedel så är sjukligheten och dödligheten fortfarande betydande. Hjärtsvikt leder till en förändrad kärlreaktivitet generellt i cirkulationen, dock är betydelsen av denna endast känd i mindre omfattning.&lt;br/&gt;&lt;br&gt; Studierna har visat att blodkärlen på patienter med olika grad av hjärtsvikt har en generell kärldysfunktion.&lt;br/&gt;&lt;br&gt; Huvudfynden i avhandlingen är&lt;br/&gt;&lt;br&gt; 1. Patienter med högt NT-proBNP (&amp;gt;5000) har en 50 % dödlighet inom 3 månader trots ” state - of- the- art” behandling. Mycket återstår att göra för denna patient grupp.&lt;br/&gt;&lt;br&gt; 2. Hudens mikrocirkulation är reducerad hos hjärtsviktspatienter beroende på blodkärlsdysfunktion, ålder och grad av inflammation.&lt;br/&gt;&lt;br&gt; 3.

Women with different hormone profiles were investigated, their colonic microbiota was characterized, and the impact of lifestyle and risk factors for GI disease were examined. In a pilot study, the relation between vaginal and rectal lactobacilli flora and hormone levels was investigated in 20 fertile and 20 postmenopausal women. No correlation was found between the overall levels of Lactobacillus species in the vagina and rectum, and no variations in sex hormone levels were found. L. plantarum was most often found in the rectal flora of both fertile and postmenopausal women, and L. crispatus was found more often in the vaginal flora of fertile women than in that of postmenopausal women. We characterized the mucosa-associated microbiota in the ascending colon in two women with collagenous colitis. After cloning and sequencing of the bacterial 16S rRNA genes, we found that the overall composition of the colonic microbiota was similar to that of a healthy woman and consists of a predominance of Firmicutes and Bacteroidetes. Interestingly, both patients had a high proportion of potentially pathogenic species of Bacteroides and clones related to Clostridium clostridioforme. Gastroparesis and esophageal dysmotility are common complications of diabetes mellitus in both symptomatic and asymptomatic patients. In a cross-sectional study, we evaluated esophageal and gastric motility, GI symptoms, secondary complications, and plasma biomarkers in consecutive patients with diabetes mellitus. We found an unexpectedly high prevalence of esophageal dysmotility, which presented as a strong association with retinopathy. Furthermore, the majority of patients suffered from GI symptoms that were not associated with objectively measured dysmotility A total of 131 female patients with microscopic colitis (MC) were examined with regard to smoking and alcohol habits compared to population-based controls. The main finding was that current smoking – independently of other lifestyle factors – was associated with an increased risk of developing persistent MC or MC with concomitant irritable bowel syndrome (IBS)-like symptoms, but current smoking was not associated with the development of solely MC without IBS symptoms. Past smoking was associated with transient MC. Taken together, some GI disorders are more common in women. No obvious hormonal explanation could be found, although the rectal lactobacilli flora was not as sensitive as the vaginal lactobacilli flora to hormonal influences. The microbiota in the colon of patients with MC is similar to healthy individuals, but with a higher proportion of Bacteroides. Men and women with diabetes mellitus have the same amount of symptoms and dysmotility when examined consecutively. Esophageal dysmotility is more common than gastroparesis in patients with diabetes mellitus, and it is strongly associated with retinopathy. Smoking is an important risk factor in the development of MC independently of other lifestyle factors.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/658eb068-1607-464e-800c-b5cd16cfb466</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Ritas_kappa_e-spik.pdf">https://portal.research.lu.se/files/3238120/4779223.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1238933</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Gastroenterology</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Gastroenterology and Hepatology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-037-1</identifier> <identifier type="oldLupId">4779222</identifier> <part> <detail type="volume"> <number>2014:108</number> </detail> <extent unit="pages"> <total>85</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-07T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>658eb068-1607-464e-800c-b5cd16cfb466</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:26+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:26+02:00</recordDateApproved> </recordInfo> </mods>

In study 1 we tested creatinine, estimated glomerular filtration rate (eGFR) with Cockroft-Gault (CG) and the MDRD equations and also microalbuminuria (MA) as predictors of CVD, stroke and CVD death. In Study 2 we tested cystatin C and compared it to eGFR estimated with the MDRD, CKD-EPI 2009 and the CKD-EPI-comb (combining creatinine and cystatin C) formulas as predictors of CVD, CVD mortality and all-cause mortality. In study 3 we investigated whether or not there is a causal relationship between cystatin C and the risk of coronary artery disease (CAD) using a Mendelian Randomization approach. In study 4 we related common genetic variance of a renal sodium channel (ENaC) remover/regulator (NEDD4L) to the 6-month blood pressure lowering effect and risk of CVD in patients treated with β-blockers and/or thiazide diuretics and in patients treated with the Ca+-channel blocker diltiazem. In patients with hypertension, creatinine and CG predicted CVD endpoints in a linear fashion, whereas the risk associated with MDRD increased steeply at a GFR &amp;lt; 40 ml/min/1.73m2. Presence of MA increased the risk with 30% but there was also a significant interaction between MA and reduced eGFR. In the healthy population, plasma cystatin C was a stronger predictor of all endpoints than creatinine based eGFR. CKD-EPI-comb was better than purely creatinine based eGFR but not as good as cystatin C. We observed no increase in risk of CAD in subjects with genetically elevated cystatin C suggesting that cystatin C not is causally related to CAD development but rather reflects other CAD risk factors such as impaired renal function. Hypertensive patients who carry the G-allele (GG and GA) of the NEDD4L rs4149601 variant and were treated with β-blockers or diuretics had greater reduction in BP and better protection against CVD compared AA allele carriers. In contrast, there was no difference in treatment response or CVD risk in G allele carriers compared to AA allele carriers in hypertensive patients treated with Diltiazem. &lt;br/&gt;&lt;br&gt; In conclusion, the relationship between creatinine based eGFR and CVD is dependent on presence of MA. Cystatin C is a better predictor of CVD than creatinine-based measures of eGFR but does not seem to be causally related to CVD. Genetic variation of NEDD4L may identify responders to antihypertensive therapy with β-blockers or diuretics.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Populärvetenskaplig sammanfattning&lt;br/&gt;&lt;br&gt; Kardiovaskulär sjukdom (CVD) är ett i vårt samhälle växande problem där allt fler insjuknar i akuta hjärtinfarkter, stroke eller hjärtsvikt. Överlevnaden efter insjuknandet har förbättrats med åren med hjälp av nya mediciner och invasiva ingrepp såsom stentning av kranskärlen vid svår kärlkramp och direkt i det akuta skedet vid vissa typer av akut hjärtinfarkt. De bakomliggande orsakerna till CVD är delvis orsakat av miljön, det vill säga till viss del av påverkbara faktorer såsom fetma, rökning och inaktivitet. Bakomliggande medicinska orsaker är diabetes och framför allt högt blodtryck (hypertoni). Hypertoni är den i världen viktigaste orsaken till insjuknande och död i kardiovaskulär sjukdom. Uppkomsten av hypertoni kan till en liten del (&amp;lt; 10 %) förklaras av bakomliggande faktorer såsom åderförkalkning i blodförsörjningen till njurarana (njurartärstenos), hormonell rubbning orsakat av sjudommar i binjurebarken eller märgen men i de allra flesta fallen känner man ej till de bakomliggande orsakerna till hypertonin. Den vanligaste formen (&amp;gt; 90 %) av hypertoni är således den vi inte kan förklara och den kallas essentiell hypertoni. Med studier inom familjer, tvillingar och adopterade barn har man kunnat uppskatta att ärftlighet är en viktig del av uppkomsten av essentiell hypertoni. Ärftlighet utgör c:a 30-50% av grundorsaken till hypertoni.&lt;br/&gt;&lt;br&gt; Kroniskt nedsatt njurfunktion (CKD) är en vanlig åkomma och drabbar cirka 10 % av befolkningen. Endast ett fåtal av de med CKD får så kraftigt nedsatt njurfunktion att de behöver gå i dialys eller njurtransplanteras. Den största risken med nedsatt njurfunktion är den påtagligt ökade risken för CVD. Det finns ett distinkt samband mellan hypertoni och CKD där hypertoni ökar risken för CKD men även det omvända gäller där patienter med CKD har ökad risk för att även drabbas av hypertoni. Ju mer nedsatt njurfunktion desto större är risken för CVD. Det har utförts många studier på olika patientgrupper med redan etablerad CVD där man idag vet att det finns ett samband mellan redan lätt nedsatt njurfunktion och ökad risk för hjärtinfarkt, stroke eller död men vad det innebär för en individ utan andra sjukdomar att bara ha ett avvikande laboratorieprov som visar lätt nedsatt njurfunktion vet man mycket lite om.&lt;br/&gt;&lt;br&gt; Inom sjukvården uppskattar man grovt njurarnas funktion med ett blodprov, kreatinin. Man kan uppskatta hur mycket av blodet som filtreras igenom njurarna per minut med olika formler baserat på kreatininvärdet där ålder och kön inkluderas (MDRD formelen) och Cockroft-Gault (CG) formeln inkluderar även vikt och kroppsyta. I båda formlerna justerar men även för ras. Uppskattning av eGFR används bland annat för att ställa diagnostisera njursjukdom och inför läkemedelsdosering som kan vara beroende av njurfunktionen. På senare år har ett nytt blodprov börjat användas för att uppskatta njurfunktionen, cystatin C. Cystatin C har fördelar över kreatinin då det till mindre grad påverkas av bland annat muskelmassa, kön och ålder. Det har även dykt upp en ny kreatininbaserad formel för eGFR som kallas CKD-EPI 2009 samt CKD-EPI-2012 som kombinerar både kreatinin och cystatin C. Den sistnämnda formeln kallar vi CKD-EPI-comb i avhandlingen.&lt;br/&gt;&lt;br&gt; Denna avhandling baseras på fyra delarbeten och syftet med denna avhandling var bland annat att närmare undersöka och jämföra olika variabler för att mäta njurfunktion och utröna vad lätt nedsatt njurfunktion innebär med avseende på risken för att insjukna i eller att dö i CVD, både i den ”vanliga befolkningen” och studerat specifikt hos de med känd hypertoni (Studie I-II). Vi studerade även ett specifikt mått på njurfunktion (cystatin C) för att utreda om det finns att kausalitetssamband mellan förhöjt cystatin C och CVD (Studie III) och avslutningsvis, att med genetiska analyser se om man kan identifiera individer som är bättre lämpade att erhålla en av två behandlingsstrategier mot högt blodtryck med avseende på den blodtryckssänkande effekten men även sett utifrån risken att insjukna i eller att dö i CVD.&lt;br/&gt;&lt;br&gt; Delarbete I&lt;br/&gt;&lt;br&gt; Hos 10881 individer med högt blodtryck jämförde vi olika mått på njurfunktion och hur de kunde användas som riskmarkörer för att förutspå risken att drabbas av hjärtinfarkt, stroke eller död av detta. Vi analyserade ett blodprov för kreatinin och två olika matematiska formler baserat på kreatininvärdet för att beräkna njurarnas filtrationsförmåga, estimerad glomerulär filtrationshastighet (eGFR). Vidare undersökte vi vad mindre mängder äggvita i urinen, mikroalbuminuri (MA) har för betydelse avseende risk för hjärtinfarkt, stroke eller död av detta. Slutsaten var att hos patienter med mycket högt blodtryck är nedsatt njurfunktion och mikroalbuminuri starka indikatorer för ökad risk för CVD och död. T.ex. ger varje ökning av kreatininvärdet med 10 µmol/L en ökning av risken för CVD med 5 % och var 10 ml/min/1.73m2 sänkning av eGFR ger 13 % riskökning. Vidare visade vi att förekomsten av MA ger en ~ 30 % riskökning och att riskökningen är beroende av eGFR där tilltagande sänkning av eGFR ger kraftigt ökad MA relaterad risk. Det föreligger således en synergism mellan eGFR och MA avseende risken för CVD. Slutsatsen är att hos patienter med grav hypertoni är mått på njurfunktion och MA viktiga riskmarkörer och de bör ingå i rutinkontrollerna hos patienter med pågående hypertonibehandling. Samtidig förekomst av nedsatt njurfunktion och MA bör föranleda en ännu mer aggressiv behandling för att få ned blodtrycket till acceptabla nivåer.&lt;br/&gt;&lt;br&gt; Delarbete II&lt;br/&gt;&lt;br&gt; I Studie II har vi tagit del av Malmö Kost-Cancer studien (MKC) där man har inkluderat drygt 30000 Malmöbor mellan åren 1991 och 1996 för att studera bland annat orsaker till uppkomsten av tumörsjukomar och CVD. Drygt 6000 av dessa individer blev dessutom inkluderade i en delstudie (den kardiovaskulära kohorten) där man tog mer blodprover och undersökte halskärlen med ultraljud för att studera förekomsten av åderförkalkning. Vi analyserade blodprovet cystatin C hos 4650 individer från den kardiovaskulära kohorten i MKC och jämförde cystatin C med MDRD, CKD-EPI 2009 samt CKD-EPI-comb och utredde vilken metod som bäst förutspår risken för CVD. Slutsaten är att cystatin C överlägset förutspår risken för CVD. Dock krävs det väldigt hög precision när man skall använda ett test som riskmarkör vid en vanlig åkomma och där kan man säga att trots att cystatin C är betydligt bättre än de kreatininbaserade formlerna för eGFR så tillför det begränsad tilläggsinformation i förhållande till de idag använda riskmarkörena för CVD, t.ex. ålder, kön, hypertoni, diabetes, rökning och blodfetter.&lt;br/&gt;&lt;br&gt; Delarbete III&lt;br/&gt;&lt;br&gt; Förhöjda nivåer i blodet av cystatin C har i vissa studier visat sig förutspå CVD risk även vid normal njurfunktion och det har spekulerats i om cystatin C kan ha direkt skadliga effekter på hjärta och kärl. I den tredje delstudien undersökte vi om genetiskt förhöjda nivåer av cystatin C är associerat med risken för CVD för att utröna om det föreligger ett orsakssamband mellan cystatin C och CVD. Vi började med att genotypa en variant av cystatin C genen och kunde konstatera att de som bär på ett anlag av genotypen (C-allel bärare) har betydligt högre cystatin C nivåer än de som bär på det andra anlaget (T-allel bärare). &lt;br/&gt;&lt;br&gt; För att få tillräcklig statistisk styrka i studien slog vi samman data från MDC (3200 fall med CVD och 24428 kontroller) och CAARDIoGRAM (en meta-analysis som utgörs av 14 sammanslagna genetiska studier utgörandes av 22233 individer med CVD och 64762 individer som utgör kontroller, samtliga med europeiskt påbrå). Vi konstaterade att genetiskt förhöjda nivåer av cystatin C ej är korrelerade med CVD och att ett orsakssamband mellan cystatin C och CVD därför är mycket osannolikt.&lt;br/&gt;&lt;br&gt; Slutsatsen är att förhöjda nivåer av cystatin C är en markör för ökad risk av att drabbas av CVD. Dock orsakas denna risk inte av cystatin C i blodet utan utav att cystatin C återspeglar nedsatt njurfunktion och andra riskfaktorer som är associerade med nedsatt njurfunktion.&lt;br/&gt;&lt;br&gt; Delarbete IV&lt;br/&gt;&lt;br&gt; I sista arbetet i avhandlingen studerade vi genetisk variation av ett protein som kontrollerar återupptaget av salt (natrium) genom en kanal i njurarna (”NEDD4L”) och hur två olika behandlingsregimer av hypertoni påverkas av denna genetiska variation med avseende på sänkning av blodtrycket och risken för insjuknande och död i hjärtinfarkt och stroke. De två behandlingsregimerna var betablockad och/eller vätskedrivande (tiaziddiuretika) samt behandling med en calciumantagonist (diltiazem) och effekten av dessa behandlingar undersöktes hos 5152 svenska individer med känd hypertoni. Patienterna följdes upp i ett genomsnitt av 4.5 år. Slutsatsen är att individerna som är bärare av en G-allel (AG eller GG genotyp) av NEDD4L genen och behandlas med betablockad/diuretika har ett bättre blodtryckssvar samt drabbas/dör i mindre utsträckning av hjärtinfarkt och stroke än de som inte bär på en G-allel (AA genotyp) eller om de istället behandlas med diltiazem.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattning&lt;br/&gt;&lt;br&gt; Cystatin C är en bättre riskmarkör för CVD än de kreatininbaserade eGFR formlerna och vi har uteslutit att det skulle finnas ett kausalsamband mellan cystatin C och CVD. Som riskmarkör hos tidigare friska medelådlers individer tillför dock cystatin C inget nytt jämfört med redan kända väletablerade riskfaktorer för CVD. Däremot hos patienter med svår hypertoni är nedsatt njurfunktion, framförallt med samtida förekomst av äggvita i urinen, en betydande riskfaktor som bör få större uppmärksamhet vid behandlingen av hypertoniker än vad den har idag och vi föreslår att hos patienter med höga blodtryck bör njurfunktion och äggvita i urinen ingå i rutinkontrollerna. Vidare konstaterar vi att med genetisk testning kan individer identifieras som svarar bättre på en typ av behandling än en annan. Vi tror att framtida forskning kommer att leda till genetiskt designade läkemedel där man skräddarsyr behandlingen beroende på individens genotyp och att detta kommer att leda till både säkrare och effektivare behandlingsmetoder.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/893d5c8f-5f8b-47b2-be58-53d96404b79f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandlingen_140109_clean.doc">https://portal.research.lu.se/files/3241577/4238617.doc</url> </location> <physicalDescription> <internetMediaType>application/msword</internetMediaType> </physicalDescription> <note type="fileSize">8576512</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Hypertension and Cardiovascular Disease, Department of Clinical Sciences, Malmö</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>eGFR</topic> <topic>creatinine</topic> <topic>cystatin C</topic> <topic>CKD-EPI</topic> <topic>CKD</topic> <topic>CVD</topic> <topic>Genetics</topic> <topic>Blood Pressure</topic> <topic>Hypertension</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-35-9</identifier> <identifier type="oldLupId">4238508</identifier> <part> <detail type="volume"> <number>2014:12</number> </detail> <extent unit="pages"> <total>129</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-01-31T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>893d5c8f-5f8b-47b2-be58-53d96404b79f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:37+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:37+02:00</recordDateApproved> </recordInfo> </mods>

This study investigates how a state-owned enterprise, the Swedish Tobacco Monopoly, reduced its labour inputs because of changed consumer preferences and mechanization in the 1920s and 1930s. By combining qualitative and quantitative evidence, the study addresses questions about the ways of achieving reductions, categorization of workers and decision-making. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; It is shown that most of the reduction was achieved by reducing the number of workers. Attrition, early retirements and buyouts accounted for about half of the reduction and layoffs for the other half. The management initially made cuts at both ends of the age distribution, but with the advent of mechanization, downsizing measures became more focused on older workers and the principle ‘last in, first out’ was abandoned in favour of a more need-based approach to layoffs. This policy shift was associated with an increased inclination of the management to involve the union in establishing the order of selection, which was a dilemma for the union leaders.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Gender was an important aspect of the downsizing process. Women were in the majority in the Swedish tobacco industry, but male workers had a strong position in the union. Tensions between union members of different sex arose after the management had been persuaded to substitute male for female workers in 1927. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Although downsizing involved delicate trade-offs for the company as well as the union, both organizations eventually managed to overcome the challenges. The Swedish Tobacco Monopoly is an example of a state-owned enterprise that was able to shed labour and take advantage of new technology.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ba2abf1f-737b-4ce6-82fd-be1720a10f65</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Downsizing_20080825c.pdf">https://portal.research.lu.se/files/3242011/1852924.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1193919</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>severance pay</topic> <topic>human capital</topic> <topic>internal labour markets</topic> <topic>economic history</topic> <topic>tobacco industry</topic> <topic>state-owned enterprises</topic> <topic>the Swedish Tobacco Monopoly</topic> <topic>the Swedish Tobacco Workers’ Union</topic> <topic>gender</topic> <topic>male-breadwinner norm</topic> <topic>mechanization</topic> <topic>workforce reductions</topic> <topic>hours-reductions</topic> <topic>layoffs</topic> <topic>inter-war period</topic> </subject> <subject authority="lup"> <topic>Economic History</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in Economic History</title> </titleInfo> <identifier type="issn">1400-4860</identifier> <identifier type="oldLupId">1223960</identifier> <part> <detail type="volume"> <number>47</number> </detail> <extent unit="pages"> <total>329</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-09-27T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>ba2abf1f-737b-4ce6-82fd-be1720a10f65</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:43+02:00</recordDateApproved> </recordInfo> </mods>

More specific aims were as follows: to determine what children are affected by thrombosis; to discern any gender or age differences related to thrombosis; to identify prothrombotic risk factors; to ascertain whether autoantibodies against coagulation proteins constitute a risk factor for childhood thrombosis; to study girls receiving estrogen treatment with regard to induced hemostatic changes and efficacy of the therapy; to investigate long-term effects on the hemostatic system in children subjected to heart surgery.&lt;br/&gt;&lt;br&gt; Material and methods: Children with thrombosis (Papers I and II) and children at risk of thrombosis (Papers III and IV) were investigated. In the initial study, 128 children referred for a first thrombotic event were retrospectively evaluated. In a subsequent endeavor, 57 children with thrombosis were prospectively included and evaluated for thrombotic risk factors, and patients and controls were investigated for autoantibodies. Considering children at risk, 63 girls treated with high doses of ethinyl estradiol were studied. Furthermore, 28 children with congenital heart defects were evaluated before and after Fontan surgery, and the results of follow-up global coagulation tests in patients and controls were analyzed.&lt;br/&gt;&lt;br&gt; Results and conclusions: The present studies showed a bimodal age distribution in pediatric thrombosis patients in Sweden, with peaks in frequency rates during the neonatal period and in adolescence. The girls:boys ratio was 2:1. Of the children with thrombosis, 84% had acquired risk factors and they showed a significantly increased prevalence of inherited thrombophilia. Also, autoantibodies against prothrombin were significantly more often detected than in controls, suggesting immunological pathogenesis. Pediatric thrombosis often seem to be elicited by a combination of risk factors. Girls receiving high-dose estrogen treatment exhibited both pro- and anticoagulation abnormalities; the estrogen therapy was most effective when started at a younger bone age, and the risk of thrombosis was &amp;lt;5% and considered a safe treatment in our cohort. Post-Fontan patients had a lower incidence of procoagulant abnormalities at long-term follow-up compared to before surgery, although a subset of the subjects showed evidence of elevated thrombin generation, identified by increases in APC-PCI, as compared to controls. The results indicate that prophylaxis to prevent thrombosis in these children should be individualized.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/90aa7400-25ce-4564-86c3-d1ec884ac29f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Rask_kappa_publ.pdf">https://portal.research.lu.se/files/3242422/1270144.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2823128</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Child</topic> <topic>Estradiol</topic> <topic>Heart Defects</topic> <topic>Congenital</topic> <topic>Hemostasis</topic> <topic>Protein C Inhibitor</topic> <topic>Risk factors</topic> <topic>Thrombophilia</topic> <topic>Thromboembolism</topic> <topic>Autoantibodies</topic> <topic>Adolescent</topic> </subject> <subject authority="lup"> <topic>Pediatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-72-9</identifier> <identifier type="oldLupId">1268995</identifier> <part> <detail type="volume"> <number>2008:119</number> </detail> <extent unit="pages"> <total>64</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-13T10:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>90aa7400-25ce-4564-86c3-d1ec884ac29f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:48+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:48+02:00</recordDateApproved> </recordInfo> </mods>

One part of this thesis investigates whether knowledge about viewers&apos; gaze positions as measured by an eye-tracker can be used to improve compression efficiency of digital video; regions not directly looked at by a number of previewers are lowpass filtered. This type of video manipulation is called off-line foveation. The amount of compression due to off-line foveation is assessed along with how it affects new viewers&apos; gazing behavior as well as subjective quality. We found additional bitrate savings up to 50% (average 20%) due to off-line foveation prior to compression, without decreasing the subjective quality.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In off-line foveation, it would be of great benefit to algorithmically predict where viewers look without having to perform eye-tracking measurements. In the first part of this thesis, new experimental paradigms combined with eye-tracking are used to understand the mechanisms behind gaze control during scene perception, thus investigating the prerequisites for such algorithms. Eye-movements are recorded from observers viewing contrast manipulated images depicting natural scenes under a neutral task. We report that image semantics, rather than the physical image content itself, largely dictates where people choose to look. Together with recent work on gaze prediction in video, the results in this thesis give only moderate support for successful applicability of algorithmic gaze prediction for off-line foveated video compression.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0f01bc03-ce12-44d5-9b73-3fc448102aeb</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Nystrom_Thesis_080829_Final.pdf">https://portal.research.lu.se/files/3245521/1222635.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4904250</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Electrical and Information Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>gaze prediction</topic> <topic>off-line foveation</topic> <topic>scene perception</topic> <topic>eye-tracking</topic> <topic>compression</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">1222627</identifier> <part> <extent unit="pages"> <total>139</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-09-26T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>0f01bc03-ce12-44d5-9b73-3fc448102aeb</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:51+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-24T08:32:26Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:51+02:00</recordDateApproved> </recordInfo> </mods>

The objective of this thesis was to clarify some of the methodological pitfalls in interpreting umbilical cord blood gases and lactate values at birth. Study I pinpoints the methodological confounding in calculating base deficit (BD) with algorithms used in different brands of blood gas analyzers and reports the consequences for diagnosing metabolic acidosis (MA) at birth. Neonatal MA rates cannot be compared between maternity units or between scientific articles where different fetal compartments (blood or extracellular fluid) and different algorithms for calculating BD have been used. Study II addresses the issue of possible diagnostic discrepancies when acid-base parameter value decimals are rounded off. A drift of a dichotomy parameter value cut-off due to decimal rounding will result in a shift in distribution of negative and positive cases in a population sample. The findings warrant a discussion on standardization of round-off rule and the number of decimals for a specific analyte result. Study III demonstrates that delayed cord blood sampling with intact pulsations affects umbilical acid-base values and hematological parameters in both vaginal and cesarean deliveries. The changes were more marked after vaginal delivery. A change towards acidemia and lactemia can be explained by the hidden acidosis phenomenon, i.e. a surge into the central circulation of peripherally trapped acid metabolites when the newborn starts to breathe. Study IV shows that clinical characteristics have a significant influence on the distribution of veno-arterial and arterio-venous gradients &lt;br/&gt;&lt;br&gt; (Δ values) in umbilical cord blood. Validation criteria based on fixed ΔpH and ΔpCO2 values may then exclude correct samples of clinical outliers. Lactate cannot be used for validation of umbilical cord blood samples. A negative ΔpO2 value indicates delayed cord blood sampling or mix-up of samples and is the only certain validation criterion.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Förlossnings- och barnläkare har i många år sökt efter ett instrument för utvärdering av det nyfödda barnets hälsotillstånd. Virginia Apgar introducerade 1953 ett poängsystem som bygger på en subjektiv bedömning av barnets hudfärg, hjärtfrekvens,reflexer/retbarhet, muskeltonus och andning. Koncentrationen i blodet av olika gaser, syror och baser speglar också det nyfödda barnets tillstånd. Relationen mellan påverkade blodgaser och det nyfödda barnets vitalitet uppmärksammades för första gången 1958 av James m.fl. Mätning av pH i blodprov från fosterskalpen&lt;br/&gt;&lt;br&gt; under förlossningen introducerades av Erich Saling från Berlin på 1960-talet. Metoden introducerades i Sverige på 1970-talet och har sedan använts för bedömning av syrebrist (hypoxi) hos fostret under förlossningen. Som första klinik i landet införde man i Malmö 1981 rutinmässig mätning av blodgaser i navelsträngsblod när barnet var fött. Några år senare infördes rutinen även i Lund. Numera använder många kliniker, både i Sverige och utomlands, mätning av blodgaser och mjölksyra (laktat) i navelsträngsblod. Blodgaser och laktatnivåer i navelsträngsblod&lt;br/&gt;&lt;br&gt; används som ett viktigt instrument för att retrospektivt utvärdera förlossningsförloppet i det enskilda fallet, för att värdera kvaliteten på förlossningsvården, vid undervisning samt som utfallsparameter i vetenskapliga artiklar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Syra-bas-balansen i navelsträngsblod är till skillnad från Apgar-poäng ett objektivt mått på barnets tillstånd vid födelsen och reflekterar inte bara den hypoxi som fostret exponerats för utan även fostrets förmåga att bemästra denna syrebrist. Fostret utvecklar med ökande graviditetslängd en blandad metabolisk och respiratorisk acidemi, dvs. sjunkande pH pga. ansamling av sura metaboliter och koldioxid. Under&lt;br/&gt;&lt;br&gt; förlossningen utsätts fostret för en hypoxisk provokation. Det innebär bl.a. att pH sjunker och laktat stiger i navelsträngsblod. Övergående hypoxi och koldioxidansamling (hyperkapni) är ofarligt, men om fostret inte klarar av att upprätthålla en aerob metabolism måste den anaeroba metabolismen utnyttjas och blodgaser och laktat ändras då mer än vad som förväntas. Detta leder till laktatansamling, acidos&lt;br/&gt;&lt;br&gt; och ett större underskott av baser (base deficit, BD). Metabolisk acidos (MA) i navelsträngsblod indikerar att fostrets utsatts för betydande hypoxi och definieras som ett pH-värde &amp;lt;7,00 (eller &amp;lt;7,05) plus ett BD-värde ≥ 12,0 mmol/L i arteriellt navelsträngsblod vid födelsen. Både en uttalad fetal acidos och låga Apgar-poäng korrelerar med en ökad risk för sjuklighet och är därför ett observandum som ofta leder till att det nyfödda barnet förs till neonatal intensivvård. Lyckligtvis klarar sig de flesta barn med låga Apgar-poäng eller acidos utan kvarstående men, vilket talar för att dessa parametrar är trubbiga instrument för utvärdering av det nyfödda barnets hälsotillstånd och fortsatta utveckling. Endast då dessa mått är kraftigt påverkade ses en tydlig koppling till kvarstående sjuklighet. Apgar-poäng och navelsträngsprover kan dock komplettera varandra och är idag fortfarande det bästa som finns att tillgå för bedömning av det nyfödda barnets tillstånd.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Blodproverna bör tas från både venen och en av de två artärerna i navelsträngen för att man bäst ska kunna bedöma allvarlighetsgraden och durationen av en eventuellt genomgången syrebrist. Venen innehåller det blod som förs från moderkakan till fostret och artärerna det blod som förs tillbaka till moderkakan från fostret. Därför reflekterar arteriellt blod bäst det nyfödda barnets syra-bas-status medan det venösa blodet dessutom återspeglar moderns syra-bas-balans och moderkakans funktion. Proverna bör tas direkt efter födelsen, då försening kan leda till förändringar av blodgaser och laktat i blodet. Detta sker då barnet börjar andas och sprattla och blodcirkulationen ställs om till livet utanför livmodern. Dessutom kan innehållet i proverna ändras om tiden från provtagning till analys förlängs. För att man ska kunna lita på provsvaren är det viktigt att den som tolkar navelssträngsprover är medveten om de många fysiologiska och metodologiska faktorer som kan påverka syra-bas-värden. Denna avhandling handlar om fallgropar vid mätning och tolkning av blodgaser och laktat i navelsträngsblod. De faktorer som utgör fokus för de olika delarbetena i avhandlingen är:&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I. val av algoritm och vätskerum (blod eller extracellulärvätska) vid uträkning av BD och diagnos av MA,&lt;br/&gt;&lt;br&gt; II. betydelsen av decimalavrundning av pH- och BD-värden då diagnosen MA ställs,&lt;br/&gt;&lt;br&gt; III. senareläggning av navelsträngsprovtagningen och hur det påverkar syra-basvärdena och&lt;br/&gt;&lt;br&gt; IV. sambandet mellan kliniska faktorer och valideringskriterier för urskiljning av det arteriella respektive venösa provet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie I redovisar förekomsten av MA beräknat med olika formler (algoritmer)för BD. Base deficit är en artificiell variabel som inte mäts av blodgasapparaten utan beräknas utifrån uppmätta värden av pH, partialtrycket av koldioxid (pCO2)och hemoglobin (Hb). I vissa blodgasapparater används ett bestämt Hb-värde på 9,3 mmol/L (150 g/L) för att beräkna BD, medan andra apparater använder ett uppmätt värde. Dessutom skiljer sig algoritmerna för beräkning av BD i blod respektive extracellulärvätska (ecf ). I denna studie uppmärksammar vi kliniker och forskare på att MA-diagnosen, som baseras på pH &amp;lt;7,00 plus BD ≥12,0 mmol/L, kan bero på vilken algoritm för uträkning av BD som används i blodgasapparaten.&lt;br/&gt;&lt;br&gt; Beräkningar gjordes utifrån pH, pCO2 och Hb-värden i 15 354 navelsträngsblodprover. Algoritmer för uträkning av BD hämtades dels från Clinical and Laboratory Standards Institute i USA och dels från tre olika blodgasapparater. Frekvensen MA varierade signifikant mellan de olika blodgasapparaterna beroende på sättet att beräkna BD. Ingen skillnad påvisades om man använde ett uppmätt eller bestämt Hb-värde i algoritmerna. Med tanke på att skillnaderna i förekomst av BD ≥12.0 mmol/L var upp till 426% mellan algoritmer för blod respektive extracellulärvätska är det inte förvånande att man i andra studier, som uppmärksammat våra fynd, funnit skillnader i frekvens av MA beroende på val av vätskerum. Det är ingen tvekan om att vald algoritm för beräkning av BD har stor klinisk och vetenskaplig betydelse och om BD fortsatt ska användas som ett utfallsmått bör val av algoritm standardiseras.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie II inspirerades av ett utlåtande från Vetenskapsrådet om misstänkt oredlighet i forskning. Inkonsekvent avrundning vid beräkning av MA skulle undvikas genom att ange samtliga tre decimaler i pH-värdet i vetenskapliga artiklar. Vi syftade till att illustrera inverkan av pH- och BD-decimalavrundning på diagnosen MA vid födelsen och inkluderade 18 831 navelsträngsblodprover. Blodgasapparaten vi använde (Radiometer ABL 735) rapporterade pH med 3 decimaler. Vi fann att vid avrundning av pH-värden mellan 7,045 och 7,049 med avrundningsregeln ”halva mot jämnt” (bankers’ rule, 5 avrundas uppåt om den föregående siffran är udda och nedåt om den är jämn) försvann 25 av 339 (7,4%) värden med pH ≤7,049. Då&lt;br/&gt;&lt;br&gt; avrundningsregeln ”halv uppåt” (round half-up, 5 avrundas alltid uppåt) användes försvann 27 av 339 (8,0%) värden. Således avrundades upp till 8% av acidotiska pH-värden bort. BD beräknades sedan dels med alla 3 decimalerna i pH-värdena medtagna i algoritmen, dels med avrundning av tredje decimalen utifrån de två olika avrundningsreglerna. pH ≤7,049 plus BD &amp;gt;12,000 mmol/L (75 fall) jämfördes sedan med olika sätt att avrunda till pH &amp;lt;7,05 plus BD &amp;gt;12,0 mmol/L (71-74 fall beroende på avrundningsregel). Den maximala diskrepansen var 8 fall (10,7%)där diagnosen MA försvann eller uppkom beroende på olika avrundningar. På grund av den redan komplexa redogörelsen för avrundning av pH och BD-värden tog vi inte med avrundning av pCO2-värden i kalkylerna. Eftersom tredje decimalen i pH-värdena och andra decimalen i pCO2-värdena är osäkra p.g.a. teknisk mätosäkerhet bör man fortsätta att i kliniskt arbete använda två decimaler för pH och en för pCO2. Studien visade alltså att ända upp mot 10.7% av värdena kan byta förtecken mellan metabolisk acidos och icke acidos. Samma sak gäller sannolikt även andra biokemiska substanser. I vetenskapliga beräkningar bör man vara medveten om att det på grund av matematisk avrundning av decimaler kan bli ett&lt;br/&gt;&lt;br&gt; skifte mellan ”positiva och negativa” diagnoser när vi definierar värden över och under ett fastställt gränsvärde som normalt eller icke normalt. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie III beskriver hur blodgas- och laktatvärden i navelsträngsblod ändras när man väntar med att avnavla barnet. Det finns studier som visar att blodvolym och järndepåer ökar hos det nyfödda barnet om avnavling sker först då pulsationer i navelsträngskärlen avstannat. Den extra blodvolym som shuntas från moderkakan till barnet kan underlätta omställningen till livet utanför livmodern. Detta gynnar framför allt för tidigt födda barn. Vi har tidigare visat att pH sjunker medan pCO2, partiellt syrgastryck (pO2), BD och laktat ökar vid sen avnavling efter vaginal förlossning. Baserat på observationer från djurstudier lade vi fram hypotesen att dessa förändringar beror på inflöde av sura metaboliter från perifer vävnad då det nyfödda barnet börjar andas. Under värkarbete sker en centralisering av cirkulationen till prioriterade organ såsom hjärta, hjärna och binjurar. Strax efter födelsen öppnas kärlbäddar till dåligt försörjda organ upp och sura metaboliter strömmar in i den centrala cirkulationen. Förekomsten av detta fenomen, kallat ”hidden acidosis”, ville vi demonstrera genom att jämföra blodgas- och laktatförändringar vid vaginal förlossning och planerade kejsarsnitt. Hypotesen var att hidden acidosis förekom i mindre utsträckning vid planerade kejsarsnitt eftersom dessa barn ej utsatts för den syrebrist som orsakas av kompression av navelsträngen under livmodersammandragningar. Vi inkluderade 66 vaginalt förlösta nyfödda och 58 nyfödda efter planerat kejsarsnitt. Utöver blodgas- och laktatvärden undersöktes även Hb och andelen röda blodkroppar (hematokrit) i blodet för att utesluta att förändringar i blodets sammansättning orsakade fenomenet. Vår hypotes bekräftades, men det var överraskande att signifikanta förändringar av blodgas- och laktatvärden inträffade&lt;br/&gt;&lt;br&gt; även i kejsarsnittsgruppen. Detta kunde förklaras av att ryggbedövning påverkar foster negativt och 90% av de kejsarsnittade kvinnorna i vår studie hade fått ryggbedövning. Studien kunde bara göras på fall där man förväntade sig ett friskt barn och därför hade endast två barn ett arteriellt pH &amp;lt;7,10. Det ena barnet var omedelbart piggt och alert och som förväntat sjönk pH ytterligare och laktat och BD steg inom 45 sekunder. Det andra barnet hade svårt att komma igång med andning och cirkulation och hos detta barn var blodgaser och laktatvärden&lt;br/&gt;&lt;br&gt; oförändrade under de första 45 sekunderna. Dessa observationer ger ytterligare stöd för att hidden acidosis är ett fysiologiskt snarare än patologiskt fenomen hos nyfödda. Konklusionen från studien var att vid sen avnavling, inklusive planerade kejsarsnitt, förändras blodgaser och laktat så att initialt normala navelsträngsvärden kan komma att bli onormala och diagnosen MA ställas på felaktiga grunder. Det torde bli omöjligt att definiera adekvata normalvärden för blodprov tagna vid sen avnavling eftersom alerta barn visar förändringar mot acidemi, hyperkapni och laktatemi, medan slappa och medtagna barn inte visar samma förändringar. För att erhålla adekvata provsvar utan att störa blodtransfusion till det nyfödda barnet bör provtagningen ske från en icke-klampad navelsträng strax efter födelsen. Denna studie samt vår kliniska erfarenhet visar att det är möjligt. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie IV syftade till att värdera etablerade valideringskriterier för blodgaser i navelsträngsblod. Syftet med att validera blodgaser tagna från navelsträngen är att försäkra sig om att provet kommer från en artär och inte venen eftersom artärerna för blod från fostret till moderkakan (placenta) och därmed bäst representerar fostrets metabola status. För att utesluta att man förväxlat artär med ven, räknar man ut den veno-arteriella (V-A) gradienten för pH och A-V gradienten för pCO2. Dessa värden, Δ-värden, ska teoretiskt vara positiva om provet är rätt taget. Är värdet negativt anser man att proverna är förväxlade och är värdet kring 0 anser man att båda proverna kommer från samma blodkärl. Etablerade valideringskriterier är ΔpH ≥0,02 enheter och ΔpCO2 ≥0,5 kPa, men även andra kriterier har föreslagits. Vårt material bestod av 27 233 parade blodprover. I histogrammen för ΔpH och ΔpCO2 urskildes tre subpopulationer, vilka i tur och ordning enligt etablerade&lt;br/&gt;&lt;br&gt; valideringskriterier då borde representera 1) förväxlade prover (negativa Δ-värden), 2) upprepade prov från samma kärl (värden kring 0) och 3) korrekt identifierade prover (positiva Δ-värden). Vid jämförelser av kliniska parametrar mellan dessa tre grupper fann vi signifikanta skillnader för krysttid, födelsevikt, arteriellt och venöst pH, samt förlossningssätt. Detta talar för att inte bara korrekt identifiering&lt;br/&gt;&lt;br&gt; av proverna spelar roll för distributionen av Δ-värden utan att även kliniska parametrar har en påverkan. Bland ΔpO2-värdena var 19,8% negativa, jämfört med 13,2% negativa ΔpH-värden och 14,9% negativa ΔpCO2-värden. Negativa ΔpO2-värden är en fysiologisk omöjlighet för fostret kan inte producera syrgas. I tidigare studier med sen avnavling hade vi observerat att pO2 kurvan stiger brant och accelererande i artären efter framfödandet av barnet men i venen stiger den de första 45 sekunderna för att sedan minska. Negativa ΔpO2 värden tyder alltså inte bara&lt;br/&gt;&lt;br&gt; på felaktig identifiering av proverna utan även på sen avnavling. Då vi jämförde vaginala förlossningar i Lund och Malmö fick vi stöd för att sen avnavling i många fall är orsaken till negativa ΔpO2-värden: i Lund tas blodproverna från den pulserande navelsträngen så snart det går medan navelsträngen dubbelklampas i Malmö innan provtagning. Frekvensen negativa ΔpO2-värden bland vaginalt förlösta var 7,5% (Lund) respektive 32,2% (Malmö). Detta talar starkt för att provtagningsrutinerna har haft stor betydelse och att proverna från Malmö tagits senare jämfört med proverna från Lund. När vi sållade bort alla negativa Δ-värden för pO2 och pCO2 då ΔpH beräknades, och negativa ΔpO2 och ΔpH då ΔpCO2 beräknades, fann vi att 5:e percentilen för ΔpH var 0,022 enheter och ΔpCO2 0,53 kPa räknat på Lundamaterialet. Histogrammet för Δlaktat visade endast en population varav 26,4% hade negativa värden och 8,6% 0-värden. Laktatkoncentrationen i navelsträngsblod är avhängigt en komplex samverkan mellan foster, placenta och moder, där bl.a. syra-bas-balans och laktatproduktionen i placenta har betydelse. Vår studie bekräftade tidigare studier, där somliga visat positiva och andra negativa Δ-laktatvärden. Sammanfattningsvis visade vår studie att även om valideringskriterierna delvis överensstämde med tidigare rapporterade kriterier är de beroende av kliniska karakteristika. Man riskerar därför att med valideringskriterier utesluta fall med korrekt tagna blodprover men med kliniska särdrag. Laktat kan inte användas för validering av navelsträngsprover. Det enda säkra valideringskriteriet är negativa ΔpO2 som talar för sen avnavling alternativt förväxling av arteriella och&lt;br/&gt;&lt;br&gt; venösa prover.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/42f83507-de1c-46fa-a831-320bd2c156f2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="ParisaMokaramiKappa.pdf">https://portal.research.lu.se/files/3245639/3735303.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1164655</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine, Obstetrics and Gynaecology</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Blood gases</topic> <topic>metabolic acidosis</topic> <topic>umbilical cord</topic> <topic>round-off</topic> <topic>delayed sampling</topic> <topic>validation</topic> </subject> <subject authority="lup"> <topic>Gynaecology, Obstetrics and Reproductive Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-25-3</identifier> <identifier type="oldLupId">3735297</identifier> <part> <detail type="volume"> <number>2013:55</number> </detail> <extent unit="pages"> <total>150</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/?term=Mokarami</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/22519816</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/21787363</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-05-25T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>42f83507-de1c-46fa-a831-320bd2c156f2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:52+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:52+02:00</recordDateApproved> </recordInfo> </mods>

The highest incidence rates are seen in developed countries, thereby imposing dietary and lifestyle factors in the etiology of CRC. Accumulating epidemiological evidence suggests that obesity is a risk factor for CRC in particular in men, as weak or no associations are seen in women. The reason for this sex difference is not fully understood, but hormonal factors are suggested to play an important role. CRC is a largely heterogenous disease, and colorectal carcinogenesis can be regarded as a complex process involving multiple genetic and epigenetic alterations engendering tumours with different clinicopathological features.&lt;br/&gt;&lt;br&gt; The aims of this thesis were to investigate the associations between obesity, measured as different anthropometric factors, and risk of CRC according to clinocopathological and tumour biological characteristics in men and women, respectively. In addition, the relationship between use of postmenopausal homone therapy (HRT) and oral contraceptives (OC) with CRC risk was examined.&lt;br/&gt;&lt;br&gt; All papers are based on tumours from incident CRC in the Malmö Diet and Cancer study, a large prospective population based cohort including 28098 individuals. Baseline examinations comprised anthropometric measurements, questionnaire on medications, socioeconomic- and lifestyle related factors. By the end of follow-up in 2008, 584 cases of incident CRC had been registered. Using the tissue microarray technique (TMA), immunohistochemical (IHC) expression of beta-catenin, cyclin D1, p53 and microsatellite instability (MSI) status of the tumours was investigated. KRAS/BRAF mutation status was assessed by pyrosequencing.&lt;br/&gt;&lt;br&gt; Interestingly, we found that obesity was associated with an increased risk of more advanced CRC, i.e. tumour (T)-stage 3 and 4, lymph node positive and metastatic disease, predominantly in men. Further, obesity was associated with an overall increased risk of CRC in both sexes (Paper 1). Associations of anthropometric factors with the risk of various molecular subsets of CRC revealed that obesity was not related to risk of MSI tumours, indicating that obesity influences carcinogenesis through other pathways than the MSI pathway (Paper 2). Given the sex differences in the associations between obesity and CRC, and, that HRT has been shown to be a protective factor of CRC, we also examined the associations of HRT and OC use and CRC risk in the female cohort. The principle finding was that current use of HRT was not associated with a decreased overall CRC risk as expected, but with a decreased risk of T -stage 1 and 2 CRC. Further, HRT use was associated with a lower risk of lymph node negative-, non-metastatic disease and of p53 negative- and cyclin D1 negative tumours in the rectum, but not in the colon (Paper 3). Finally, we found that obesity was associated with an increased risk of both wild-type and KRAS-mutated colorectal tumours in men, and with an increased risk of BRAF wild-type tumours, but not with BRAF-mutated tumours, in both sexes (Paper 4).</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2a56be29-bfba-4aa2-9bec-f893bc06ff8f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Jennys_kappa_1_.pdf">https://portal.research.lu.se/files/3245811/4354263.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1415522</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Pathology, (Lund)</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>colorectal cancer</topic> <topic>carcinogenesis</topic> <topic>MDCS</topic> <topic>anthropometrics</topic> <topic>risk factors</topic> <topic>sex differences</topic> <topic>hormonal therapy</topic> <topic>beta-catenin</topic> <topic>cyclin D1</topic> <topic>p53</topic> <topic>MSI</topic> <topic>KRAS mutation</topic> <topic>BRAF mutation</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-60-1</identifier> <identifier type="oldLupId">4354221</identifier> <part> <detail type="volume"> <number>2014:35</number> </detail> <extent unit="pages"> <total>104</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-03-28T09:15:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Rupture of a plaque results in clinical manifestations such myocardial infarction or stroke. Atherosclerosis is a complex disease where both autoimmune responses towards atherosclerosis-related antigens and smooth muscle repair responses play important roles. This thesis contains studies focusing on both regulatory immune responses and tissue repair mechanisms in experimental models of atherosclerosis as well as in patient cohorts.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The first part of this thesis investigates the role of regulatory immune responses targeting plaque-related antigens. In paper I, we developed a matrigel-based method to characterize T helper 2 immune responses against human apolipoprotein B100 (ApoB100). We report that matrigel loaded with the antigen of interest can be used to measure antigen-specific immune cell accumulation and cytokine production. In paper II, we report that B cells pulsed with peptide 210 (p210) from ApoB100 coupled to the cholera toxin B subunit (p210-CTB) acquire a regulatory phenotype and induce Tregs in vivo. In the third paper, we unexpectedly found increased frequencies of circulating regulatory T cells in patients with prevalent cardiovascular disease. Our results indicate that the general immune cell activation in patients with prevalent cardiovascular disease can cause a compensatory increase in regulatory T cells to counteract the immune response.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the second part of this thesis, we focused on the role of smooth muscle cells in atherosclerosis. In paper IV, we show that IL-22 is involved in controlling smooth muscle cell phenotype. More specifically, IL-22 deficient atherosclerotic mice develop smaller plaques with increased expression of contractile proteins. Increased numbers of smooth muscle cells remaining in a contractile phenotype in the media and decreased collagen content in the plaques could possibly contribute to the smaller plaque size observed in IL-22 deficient mice. Finally, in paper V, we present data suggesting that high levels of smooth muscle cell growth factors (platelet-derived growth factor, epidermal growth factor, heparin-binding epidermal growth factor) measured in plasma can reflect a fibrous plaque phenotype. In particular, high plasma levels of heparin-binding epidermal growth factor at baseline was associated with a decreased risk for developing a coronary event.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Hjärtkärlsjukdom är den främsta dödsorsaken i västvärlden och den bakomliggande orsaken är oftast ateroskleros. Ateroskleros, eller åderförkalkning, medför att blodkärlens väggar blir tjocka och förlorar sin normala rörlighet på grund av inlagring av fett och bildningen av ett s.k. aterosklerotiskt plack. Vissa kan leva med åderförkalkning ett helt liv utan att märka av det medan andra utvecklar allvarliga akuta symptom på grund av att ett plack ger upphov till en blodpropp som snabbt täpper igen kärlet. Beroende på vart placket sitter så orsaker detta syrebrist i hjärnan (stroke) eller i hjärtat (hjärtinfarkt). Flertalet riskfaktorer för hjärtkärlsjukdom är identifierade t.ex. högt kolesterol, högt blodtryck och diabetes men fler metoder behövs för att upptäcka vem som kommer att drabbas av akuta symptom eller inte. I denna avhandling har jag studerat just detta samt hur ett plack uppkommer och hur man med hjälp av nya behandlingar skulle kunna förhindra dess tillväxt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Fett som vi äter transporteras i kroppen bland annat i partiklar som kallas låg- densitet lipoprotein (LDL, det ”onda” blodfettet) och förenklat så kan man säga att ett plack bildas när fett från blodcirkulationen ansamlas i kärlväggen. LDL som lagras i kärlet kommer så småningom att modifieras på flera olika sätt, man kan säga att fettet härsknar, precis som gammalt smör. Kroppens städare, makrofagerna, kommer att kämpa för att rensa bort fettet från kärlväggen men allteftersom ansamlingen fortsätter så tappar makrofagerna kontrollen över situationen. Makrofager fulla av fett bildar s.k. ”skumceller” som till slut dör. Nivåerna av modifierat LDL tillåts nu öka ytterligare i kärlväggen vilket bidrar till att kärlet blir inflammerat. Detta resulterar i rekrytering av vita blodkroppar från blodcirkulationen och kroppen kommer att reagera precis som när vi blir infekterade av tillexempel ett virus, nämligen genom att aktivera immunförsvaret.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Immunförsvarets uppgift är delvis att försöka städa bort det okända som inte hör hemma i kroppen men i vissa fall kan immunförsvaret även känna igen och reagera på kroppens egna proteiner, t.ex. delar av modifierat LDL. En vanlig virusinfektion kommer till sist att rensas bort men vid åderförkalkning samlas mer och mer fett och immunförsvaret kommer få fortsätta att arbeta. Istället för att läka sjukdomen så förvärras utvecklingen av åderförkalkning och det bildas en kronisk inflammation i kärlväggen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den pågående inflammationen aktiverar även glatta muskelceller vars främsta uppgift är att producera proteiner för att försöka behålla kärlets normala struktur genom att läka den vävnadsskadan som håller på att uppkomma. Ackumulering av fett, immunceller, glatta muskelceller och strukturproteiner gör att placket växer inåt kärlet. Ett stort plack gör att blodet får det svårare att passera genom det åderförkalkade kärlet men placket kan även gå sönder vilket leder till att en blodpropp bildas. Balansen av de olika komponenterna i placket bestämmer vilka plack som kommer att orsaka akuta symptom eller inte. Mycket inflammation och låga nivåer av de läkande glatta muskelcellerna ökar risken för att placken ska gå sönder och orsaka akuta symptom. För att hitta de som har en hög risk för att utveckla hjärtkärlsjukdom så behövs det biomarkörer. Biomarkörer är något som finns i högre eller lägre nivåer hos dem som kommer bli sjuka och som lätt kan hittas med hjälp av ett enkelt blodprov.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Åderförkalkning är alltså en inflammatorisk sjukdom som kan liknas vid en virusinfektion. En virusinfektion kan förhindras genom vaccinering men tänk om man kunde skydda sig mot åderförkalkning på samma sätt? I min avhandling har jag studerat just detta, möjligheten att med ett vaccin stoppa utvecklingen av åderförkalkning. I studie I och II använder jag en musmodell för att undersöka möjligheten att skapa en skyddande immunreaktion mot åderförkalkning. I den första (studie I), vaccinerar vi möss och studerar den immunreaktion som skapas mot ett specifikt plackprotein (apolipoprotein B100, ApoB100). I den andra (studie II) så använder jag mig av celler som vi tror kan dämpa den pågående immunreaktionen i placken för att se om dessa kan stoppa utvecklingen av åderförkalkning. Ytterligare en typ av immun- dämpande cell studeras i studie III. Där har jag haft möjligheten att undersöka om nivåerna av dessa regulatoriska celler är annorlunda hos patienter med hjärtkärlsjukdom och/eller diabetes. Överraskande så visar vi att patienter med hjärtkärlsjukdom har högre nivåer av dessa celler.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I den andra delen av min avhandling så har jag studerat glatta muskelceller och mer specifikt, hur immunförsvaret kan reglera läkningen av kärlväggen under åderförkalkningsprocessen. I studie IV så har jag undersökt hur IL-22, en molekyl som utsöndras av immunceller för att kommunicera med vävnadsceller, t.ex. glatta muskelceller, påverkar åderförkalkning. Vi skapade en musmodell som saknade IL-22 och undersökte hur brist av IL-22 påverkar bildningen av aterosklerotiska plack. Vi rapporterar att avsaknad av IL-22 leder till att mössen får mindre plack men att detta även är associerat med en lägre nivå av glatta muskelceller som syntetiserar strukturproteiner. Detta leder till mindre plack men det skulle eventuellt kunna öka risken för att placken går sönder eftersom glatta muskelceller är viktiga för läkningsprocessen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Andra molekyler som påverkar glatta muskelceller undersöks i studie V. Här mätte vi nivåerna av tre molekyler, som stimulerar tillväxt av glattamuskelceller, i blodet hos patienter och såg att höga nivåer av dessa (PDGF, EGF, HB-EGF) kunde reflektera ett stabilt plack som innehåller mycket strukturproteiner. Höga nivåer av en av dessa tillväxtfaktorer, HB-EGF, var även kopplat till minskad risk för att utveckla akuta hjärtkärlsymptom i framtiden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Förhoppningen är att dessa studier ska bidra till kunskapen kring hur en plack bildas samt till hur vi enklare ska kunna identifiera dem som har hög risk för att drabbas av akuta symptom. I förlängningen så kan detta förhoppningsvis bidra till utvecklingen av nya terapier för att stoppa utvecklingen av hjärtkärlsjukdom.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/54a89f45-ceb0-4879-b8d6-c5ac09946e6f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa.pdf">https://portal.research.lu.se/files/3245838/4935460.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1391060</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Experimental Cardiovascular Research Unit, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Atherosclerosis</topic> <topic>Cardiovascular disease</topic> <topic>T helper 2 cells</topic> <topic>ApoB100</topic> <topic>Regulatory B cells</topic> <topic>Regulatory T cells</topic> <topic>Smooth muscle cells</topic> <topic>IL-22.</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-092-0</identifier> <identifier type="oldLupId">4927061</identifier> <part> <detail type="volume"> <number>2015:12</number> </detail> <extent unit="pages"> <total>183</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-02-06T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>54a89f45-ceb0-4879-b8d6-c5ac09946e6f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:13:54+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:13:54+02:00</recordDateApproved> </recordInfo> </mods>

Since the discovery of DNA as the carrier of genetic information, a key question in biology has been how&lt;br/&gt;&lt;br&gt; these hard coded instructions are read and regulated to maintain cellular and organismal homeostasis.&lt;br/&gt;&lt;br&gt; Understanding the mechanisms and processes governing gene and genome regulation are key to solving many of&lt;br/&gt;&lt;br&gt; the outstanding problems in medicine as all forms of disease represent a breakdown of homeostasis. The concept&lt;br/&gt;&lt;br&gt; of epigenetics, how the genotype gives rise to different phenotypes in organismal development, entered the&lt;br/&gt;&lt;br&gt; scientific vernacular in the first half of the 20th century. Increasing knowledge of the processes underlying&lt;br/&gt;&lt;br&gt; genome regulation has shifted the core emphasis of epigenetic research from the phenotypic level and towards the&lt;br/&gt;&lt;br&gt; molecular basis of genome regulation. This thesis provides a brief history and description of the concept of&lt;br/&gt;&lt;br&gt; epigenetics while summarizing basic aspects of genome regulation in order to serve as a general backdrop for the&lt;br/&gt;&lt;br&gt; larger biological context of the included works. The overall aim of the papers included in this thesis has been to&lt;br/&gt;&lt;br&gt; study the epigenetic and phenotypic landscape of urothelial carcinoma with the goal of gaining a fuller&lt;br/&gt;&lt;br&gt; understanding of the molecular alterations underlying the full spectrum of the disease.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Epigenetik handlar om hur avläsning av informationen i arvsmassan kan styras&lt;br/&gt;&lt;br&gt; och nedärvas mellan cellgenerationer. Förmågan att kunna ändra&lt;br/&gt;&lt;br&gt; genuttrycksmönster som svar på signaler från omgivningen och sedan bibehålla&lt;br/&gt;&lt;br&gt; dessa genom efterföljande celldelningar ligger till grund för korrekt funktion av&lt;br/&gt;&lt;br&gt; vävnaderna och organen som våra kroppar är uppbyggda av. Samtliga&lt;br/&gt;&lt;br&gt; sjukdomstillstånd har sin grund i en dysfunktion i samspelet mellan enskilda celler&lt;br/&gt;&lt;br&gt; och vävnadskontexten de normalt uppfyller en roll i. Tydligast är detta i cancer&lt;br/&gt;&lt;br&gt; som i grund och botten är en sjukdom karaktäriserad av ett successivt mer&lt;br/&gt;&lt;br&gt; dereglerat samspel mellan de maligna cellerna och den normala vävnaden. I mitt&lt;br/&gt;&lt;br&gt; avhandlingsarbete har jag undersökt det epigenetiska landskapet i&lt;br/&gt;&lt;br&gt; blåscancertumörer genom att studera förändringar i DNA-metyleringsmönster.&lt;br/&gt;&lt;br&gt; DNA-metylering är en kemisk modifikation som leder till bestående förändringar i&lt;br/&gt;&lt;br&gt; läsbarheten av information i arvsmassan. Förändrade DNA-metyleringsmönster är&lt;br/&gt;&lt;br&gt; starkt förknippade med tumörutveckling även om man ofta inte vet exakt vilka&lt;br/&gt;&lt;br&gt; konsekvenser en given förändring har på cellnivå. En välkänd effekt av förhöjda&lt;br/&gt;&lt;br&gt; DNA-metyleringsnivåer vid startpunkter för genavläsning, s.k. promotorer, är&lt;br/&gt;&lt;br&gt; nedstängning av genen. Genom att metylera promotorer för gener med t.ex. en&lt;br/&gt;&lt;br&gt; tillväxthämmande funktion kan tumörcellerna öka sin tillväxtpotential. Våra&lt;br/&gt;&lt;br&gt; studier har utgått ifrån blåscancertumörer från patienter behandlade för sin&lt;br/&gt;&lt;br&gt; sjukdom inom Region Skåne. Studierna har främst varit fokuserade på att&lt;br/&gt;&lt;br&gt; kartlägga storskaliga förändringar i DNA-metyleringsmönster för att kunna&lt;br/&gt;&lt;br&gt; definiera specifika patientpopulationer med distinkta metyleringsprofiler och&lt;br/&gt;&lt;br&gt; undersöka de underliggande molekylära förändringarna som ligger till grund för&lt;br/&gt;&lt;br&gt; sjukdomen. Genom våra studier har vi visat att det är möjligt att stratifiera&lt;br/&gt;&lt;br&gt; patienters tumörer baserat på metyleringsmönster och att dessa i sin tur är&lt;br/&gt;&lt;br&gt; kopplade till landskapet av uttryckta gener hos tumören. Genom att kartlägga&lt;br/&gt;&lt;br&gt; molekylära förändringar i tumörer på flera olika nivåer hoppas vi kunna förstå&lt;br/&gt;&lt;br&gt; sjukdomen samt dess uppkomst bättre och därmed kunna verka för en förbättrad&lt;br/&gt;&lt;br&gt; riskstratifiering av patienter samt för att i förlängningen hitta nya&lt;br/&gt;&lt;br&gt; behandlingsalternativ.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/061422bc-d5c1-405c-93ef-d8a821f9517f</url> </location> </relatedItem> <originInfo> <publisher>Oncology, Lund</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Epigenetics</topic> <topic>DNA methylation</topic> <topic>gene expression</topic> <topic>urothelial carcinoma</topic> <topic>bladder cancer</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-211-5</identifier> <identifier type="oldLupId">8227523</identifier> <part> <detail type="volume"> <number>2015:131</number> </detail> <extent unit="pages"> <total>66</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-12-10T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>061422bc-d5c1-405c-93ef-d8a821f9517f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:00+02:00</recordDateApproved> </recordInfo> </mods>

In practice however, random processes are observed, processed, and interpreted at a finite set of time points. For processes in continuous time, the ambiguity domain has interesting properties which makes it particularly useful. One such property is that there exists a certain relationship between scaling in the ambiguity domain and convolution in the time-lag domain. For processes in discrete time, several different definitions of the ambiguity domain have been proposed. Paper A and B of this thesis contributes to the discretization of time-frequency theory, where we in Paper A compare three of the most common definitions: the Claasen-Mecklenbräuker, the Nuttall, and the Jeong-Williams ambiguity domain. We prove that amongst these three, only the Jeong-Williams ambiguity domain has the property that there exists a bijection between scaling in this domain and convolution in the time-lag domain. For processes in continuous time, there is also a certain mapping between the mean square error (MSE) optimal smoothing covariance function estimator and the MSE optimal ambiguity function estimator. This mapping allows us to compute the MSE optimal smoothing estimator in a convenient way. In Paper B, we prove that a similar relationship is not valid between the scaling estimators in the Jeong-Williams ambiguity domain and the smoothing covariance function estimators for processes in discrete time. However, we show that the MSE optimal smoothing covariance function estimator for a non-stationary random process in discrete time can be found as the solution to a linear system of equations. It allows us to find the lower MSE bound of this family of estimators. In Paper C, we show that it is possible to compute a covariance function estimator which is MSE optimal to a set of processes in order to increase the robustness.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The cepstrum of a stationary random process has a lot of interesting applications. It is usually estimated as the Fourier transform of the log-periodogram. In Paper D, we propose a multitaper based estimator and we derive approximations of its bias and variance. We demonstrate the performance of the multitaper based estimator in a speaker verification task. In Paper E we discuss four different families of cepstrum estimators based on smoothing. We find the MSE optimal smoother in each family and the lower MSE bound of each family of estimators. The robustness of the optimal estimators within each family is also considered.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Det är ofta fördelaktigt att i olika sammanhang representera våra observationer av verkligheten med en följd av tal. Så skilda exempel som ljud, bilder, hjärnvågor, havsvattenvågor, jordbävningar och aktiekurser kan låta sig beskrivas av följder av tal. Man kan med fördel föreställa sig följden som en uppritad graf, där den horisontella axeln beskriver tidpunkten för mätningen och den vertikala beskriver storleken på det uppmätta värdet. Vi använder ordet &quot;tid&quot; för att beskriva positionen i talföljden även om talens position i somliga tillämpningar representerar något annat än olika tidpunkter. För att kunna analysera dessa följder av tal är det ofta lämpligt att utgå från att våra observationer till viss del påverkats av slumpmässiga variationer. Man säger då att följden är en observation av en tidsserie eller en stokastisk process i diskret tid. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I vissa sammanhang kan man utgå från att talen i följden är både positiva och negativa på ett sådant sätt att medelvärdet av följden är nära noll. Det gäller till exempel mätning av olika elektriska signaler och ljudvågor. För den typen av stokastiska processer är det ofta intressant att studera samvariationer mellan tal på olika ställen i följden. Samvariationen beskrivs av processens kovariansfunktion. Ibland tydliggörs viss information i kovariansfunktionen genom en transformation. Två exempel på sådana transformer av kovariansfunktionen är medelvärdet av ambiguity-funktionen och cepstrat. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ambiguity-funktionen används framförallt för stokastiska processer vars statistiska egenskaper skiljer sig åt på olika ställen i talföljden. Sådana processer kallas icke-stationära. Ambiguity-funktionen spelar en central roll inom tids-frekvens-analys. Syftet med tids-frekvens-analys är att beskriva kovariansfunktionen för en icke-stationära process som en fördelning över tid och frekvens. En liknande representation återfinns inom musiken, där noterna beskriver vid vilken tidpunkt som olika toner, dvs frekvenser, ska spelas.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Processer vars statistiska egenskaper inte förändras med tiden kallas stationära. För sådana processer används ibland cepstrat för att beskriva vissa egenskaper hos processen. Cepstrat har fått särskilt stor användning i tillämpningar där tidsserien representerar en ljudinspelning av något slag. I detta sammanhang bör man endast betrakta en mycket kort bit av ljudinspelningen i taget, eftersom kravet på att processen ska vara stationär annars inte är uppfyllt. I sammanhang då ljudet är en röstinspelning antas det ofta att cepstrat på ett förhållandevis tydligt sätt beskriver vad som sägs och vem som talar under inspelningen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Eftersom medelvärdet av ambiguityfunktionen och cepstrat beror på samvariationerna i talföljden och då dessa i praktiska tillämpningar aldrig är helt kända, kan vi i praktiken bara göra uppskattningar av medelvärdet av ambiguity-funktionen och cepstrat. Det finns olika metoder för att göra sådana uppskattningar. I den här avhandlingen bevisas vissa möjligheter och begränsningar med några sådana metoder.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/384e7bc9-57d6-4a76-8827-cfb02978dee7</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>ambiguity domain</topic> <topic>time-frequency analysis</topic> <topic>time-frequency representations</topic> <topic>covariance function</topic> <topic>non-stationary random processes</topic> <topic>Speaker recognition</topic> <topic>MFCC</topic> <topic>cepstrum</topic> </subject> <subject authority="lup"> <topic>Probability Theory and Statistics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>LUTFMS-1035-2010</title> </titleInfo> <identifier type="issn">1404-0034</identifier> <identifier type="isbn">978-91-628-8080-4</identifier> <identifier type="oldLupId">1585231</identifier> <identifier type="other">LUTFMS-1035-2010</identifier> <part> <detail type="volume"> <number>2010:3</number> </detail> <extent unit="pages"> <total>128</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-07T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>384e7bc9-57d6-4a76-8827-cfb02978dee7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:06+02:00</recordDateApproved> </recordInfo> </mods>

One aim of this thesis was to investigate how ischemia followed by reperfusion affects the large intestine and the enteric nervous system (ENS). To do so an experimental ischemia/reperfusion (I/R) model was set up using rat large intestine. In order to study how the ENS reacts to various mediators of stress, primary cultures of myenteric neurons from rat small and large intestine were used to study neuronal survival. The intestinal segments exposed to I/R were structurally well preserved, however, local areas containing numerous mast cells were detected in the muscle layers, the serosa and in and around the myenteric ganglia 4-20 weeks post ischemia. Myenteric ganglionic formations within such mast cell rich areas virtually lacked neurons. Myenteric neurons co-cultured with mast cells showed a markedly reduced neuronal survival. The increased neuronal cell death was largely due to mast cell degranulation. Identified mast cell mediators involved were proteinases acting via proteinase activated receptor 2 (PAR2), prostaglandin D2 (PGD2) and interleukin 6 (IL-6). Immunocytochemical examination of rat small and large intestine, revealed frequent co-localization of corticotropin releasing peptide (CRF), known to induce psychological stress reactions in mammals, and vasoactive intestinal peptide (VIP) in enteric neurons. CRF did not affect the survival of myenteric neurons in culture, but was found to counteract the VIP-induced neuroprotective effect. We also showed that the mast cell-induced increase in cell death of cultured myenteric neurons was not executed via CRF signaling pathways. In conclusion: I/R in rat large intestine attracted mast cells to invade the muscle layers and myenteric ganglia. In mast cell-infiltrated areas, ganglionic formations lacked myenteric neurons. Mast cells reduced neuronal survival when cultured together with myenteric neurons from rat small intestine. The mechanisms behind is through PAR2 activation and release of PGD2 and IL-6. Presence of CRF counteracted VIP-induced neuroprotection in cultured myenteric neurons.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Emotionell stress samt hårt fysiskt arbete reducerar blodflödet till tarmen. Om cirkulationen till tarmen är kraftigt reducerat under en längre period får tarmen syrebrist, den blir ischemisk. Vid ischemi bildas skadliga slaggprodukter vilka distribueras till andra organ när blodflödet ökar igen. Irritable bowel syndrome, IBS, är en vanlig mag-tarm sjukdom som man inte vet orsaken till. Patienterna är förstoppade eller har diarré, känner smärta eller obehag och är ofta svullna om magen. Det har noterats att IBS patienter har en ökad förekomst av tjocktarmsischemi. En annan patientgrupp som också drabbas av ischemi i tarm är de som har inflammatoriska tarmsjukdomar, tex Crohn’s sjukdom eller ulcerös colit. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Tarmens funktion styrs till stor del av det enteriska nervsystemet som återfinns utmed hela tarmen. Nervcellerna ligger fördelade i framförallt två typer ganglier - ansamlingar av nervcells kroppar. Myenteriska ganglier ligger mellan tarmens två muskelskikt och submucosala ganglier ligger under sleminnan. Nervcellerna skickar signaler till tarmens övriga celler, men de kommunicerar också med varandra, samt med centrala nervsystemet. Genom studier som ingår i denna avhandling har vi sökt information om hur enteriska nervceller reagerar i utsatta situationer, samt hur dessa nervceller klarar av en tillfällig period av ischemi. Genom att isolera nervceller från råttans tarm och odla dom i primärkultur utsättes de för en stressande miljö. Vi har visat att de trots denna påfrestning kan överleva och tillverka signalsubstanser. Vi har också visat att vid odling av myenteriska nervceller från råttans tjocktarm är det en högre andel nervceller som uttrycker neuropeptiderna CGRP, NPY, somatostatin och VIP jämfört med när neuronen är intakta i tarmen. Dessa peptider är viktiga för tarmens funktion och slutsaten vi drar från dessa resultat är att de också är viktiga för nervcellerna överlevnad.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att studera hur nervcellerna, samt övriga tarmstrukturer, klarar ischemi följt av reperfusion, stängdes blodflödet av under en timme till ett segment av råttans tjocktarm, för att därefter släppas på igen. Strukturellt klarade sig den behandlade tjocktarmen ganska bra, men 4-20 veckor efter ischemi återfanns mastceller, som är inflammatoriska celler, i tarmens muskellager samt i dess ytterskikt. I områden där mastcellerna ackumulerades, vilket företrädesvis var nära de myenteriska ganglierna, saknades nervceller. För att utreda detta fenomen i detalj samodlades mast celler med myenteriska neuron. Det visade sig att närvaro av mastceller markant reducerade nervcellernas överlevnad. Mastceller innehåller många mediatorer som skulle kunna påverka nervcellsöverlevnad. Proteaser via sin mottagarmolekyl PAR2, IL-6 och PGD2 är de mediatorer vi visade kunde reducera nervcellernas överlevnad i kultur. Samtidigt fann vi att VIP och en corticosteriod hade förmåga att motverka den mastcellsinducerade nervcellsdöden. Dessa två visade sig också ha en gynnsam effekt på nervcellernas överlevnad i kulturer utan mastceller.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; CRF är en peptid som frisätts vid emotionell stress. CRF och dess mottagarmolekyl produceras av mastceller samt av neuron i tarmen. I avhandlingens sista studie visade vi att råttan har många CRF innehållande nervceller i tunn- och tjocktarm och att dessa oftast också innehåller VIP. Vid odling av myenteriska nervceller återfanns relativt sätt få CRF- men många VIP-innehållande nervceller. CRF visade sig inte ha någon effekt på nervcellernas överlevnad i kultur men motverkade den neuroprotektiva effekten av VIP. Samtidigt kunde vi bekräfta att mastcellsinducerad nervcellsdöd, som noterats i samodlingarna, inte beror på närvaro av CRF.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har vi visat att myenteriska nervceller från råttans tjocktarm går att odla. Flera veckor efter en kraftig, men tillfällig, ischemi så dyker mastceller upp i tarmväggen och i dessa områden saknas myenteriska nervceller. Mastceller inducerar troligen död av nervceller mha sina mediatorer: proteas, PGD2 och IL-6, dock inte via CRF signalering. VIP är neuroprotektiv och förhindrar nervcellsdöd men denna effekt motverkas av CRF.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/cc28374c-7156-4a0c-bed7-a89e87a269b8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Neuroimmune_Interactions_of_Enteric_Neurons_and_Mast_Cells_Friends_or_Foes.pdf">https://portal.research.lu.se/files/3247793/1580533.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">614582</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>enteric neurons</topic> <topic>ischemia</topic> <topic>VIP</topic> <topic>mast cells</topic> <topic>CRF</topic> </subject> <subject authority="lup"> <topic>Gastroenterology and Hepatology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-49-8</identifier> <identifier type="oldLupId">1580463</identifier> <part> <detail type="volume"> <number>2010:34</number> </detail> <extent unit="pages"> <total>45</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-04-23T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>cc28374c-7156-4a0c-bed7-a89e87a269b8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:07+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:04:02Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:07+02:00</recordDateApproved> </recordInfo> </mods>

Aberrant Notch signaling has been implicated in tumorigenesis by perturbing control of proliferation, differentiation, apoptosis, migration and angiogenesis.&lt;br/&gt;&lt;br&gt; Neuroblastoma is an embryonal tumor derived from cells of the sympathetic nervous system, arrested at an immature stage of differentiation. Notch signaling is thought to play an important role during the development of the sympathetic nervous system, and prior studies have indicated that dysregulated Notch signaling might be associated with the perturbed differentiation that characterize neuroblastoma cells. Here we show that the histone deacetylase inhibitor valproic acid induced differentiation of neuroblastoma cells, in conjunction with activation of Notch-1 signaling. In addition, we also noted that the expression of the Notch target HES-1 was primarily regulated by ERK-MAP kinase signaling in a neuroblastoma cell line.&lt;br/&gt;&lt;br&gt; Clear cell renal cell carcinoma (CCRCC) is characterized by activation of the hypoxia inducible factor (HIF) pathway due to functional loss of the von Hippel-Lindau tumor suppressor gene. However, cooperating oncogenic events parallel to the HIF pathway remains poorly described. Our results presented here imply a growth-promoting role for Notch signaling in CCRCC cells, seemingly independent of HIF-regulated cellular events. Treatment of nude mice bearing CCRCC xenografts, with daily injections of a Notch inhibitor (γ-secretase inhibitor) in cycles of 3 days followed by 4 days without treatment, retarded tumor growth and minimized the adverse effects commonly associated with γ-secretase inhibition. In addition, analysis of primary CCRCC samples revealed that Notch-1 and Jagged-1 were expressed at significantly higher levels compared to normal kidney tissue samples. Finally, we found that inhibition of Notch signaling decreased the migratory potential of CCRCC cells. This effect might be linked to a cross-talk between Notch and TGF-β signaling in CCRCC cells.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/abafd141-06dc-40ae-b0c4-5972fc194c62</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Notch_signaling_in_neuroblastoma_and_renal_cell_carcinoma.pdf">https://portal.research.lu.se/files/3248325/949713.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">11120000</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Molecular Tumour Biology</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>differentiation</topic> <topic>clear cell renal cell carcinoma</topic> <topic>neuroblastoma</topic> <topic>TGF-beta</topic> <topic>migration</topic> <topic>γ-secretase</topic> <topic>valproic acid</topic> <topic>cancer</topic> <topic>Notch</topic> <topic>ERK</topic> <topic>von Hippel-Lindau</topic> <topic>hypoxia</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> <topic>Clinical Medicine</topic> <topic>Medical and Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-61-2</identifier> <identifier type="oldLupId">949628</identifier> <part> <detail type="volume"> <number>2008:8</number> </detail> <extent unit="pages"> <total>60</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-02-15T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>abafd141-06dc-40ae-b0c4-5972fc194c62</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:12+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:12+02:00</recordDateApproved> </recordInfo> </mods>

A hospital-based advanced home care programme was initiated, in order to enable patients to remain at home for a longer period and to choose to die at home. The allocation to advanced home care (AHC) or conventional care (CC) was performed according to the patients’ preferences. This intervention offered an opportunity to investigate the effect of AHC and to describe the HRQL of patients with a progressive, life-threatening disease. A prospective longitudinal comparative study was performed. The two groups of patients (AHC and CC) were compared and the main outcome variables were place of death, time spent in institution or at home, and the patients’ HRQL. The latter was assessed monthly by using self-reported questionnaires, including the European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30), the Impact of Event Scale (IES), five questions about social support and two items concerning general well-being. The AHC patients spent more time outside the hospital and more died at home compared with patients in the CC group. Compared with the CC patients, patients who chose the AHC programme had lived longer with their cancer diagnosis, had a shorter survival period after study enrolment, and had poorer performance status. A marked, but gradual deterioration was seen during the patients’ last three months of life. A more rapid increase in problems was observed between two and one month before death regarding Physical, Cognitive and Social function, as well as Fatigue. The mean scores for Pain, Nausea/Vomiting, Sleeping problems, Diarrhoea and Financial impact were stable over time. Patients who dropped out of the study after filling in the first questionnaire after inclusion had a less favourable prognosis, with regard to both clinical variables and HRQL data. This pattern was not found from patients dropping out of the study during the last two months before death. The palliative intervention with AHC proved successful. Dying at home is strongly associated with the patients’ preference to do so. The results indicate that patients are reluctant to accept home care until necessary due to the severity of functioning impairments and symptom burden. It is important to be aware of the high level of symptoms in the patients’ last three months of life. Symptom assessment using standardised questionnaires may enhance the focus on symptom management. Results from HRQL studies must be interpreted with care due to non-random attrition. This is less evident close to death.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/79eda70d-8230-41d7-8242-1424e9c7b081</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-38-5</identifier> <identifier type="oldLupId">1218793</identifier> <part> <detail type="volume"> <number>2008:85</number> </detail> <extent unit="pages"> <total>95</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-09-27T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>79eda70d-8230-41d7-8242-1424e9c7b081</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:22+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:22+02:00</recordDateApproved> </recordInfo> </mods>

Comparing the measurements of the capsular distance set with a caliper/ruler with those performed with ultrasonography on a THA model demonstrated a high correlation between measurements. The effect of experience of ultrasonography in THA was also evaluated comparing the first and last series of examinations. It was shown that intra/ inter observer agreement increased with increasing&lt;br/&gt;&lt;br&gt; number of examinations.&lt;br/&gt;&lt;br&gt; The pain in osteoarthritis (OA) and its relation to the elastic properties of the hip joint capsule was analyzed. In OA patients intracapsular pressure&lt;br/&gt;&lt;br&gt; and capsular elasticity, i.e. compliance, was measured. Pain assessment, radiographic evaluation and ultrasonography measuring the anterior capsular&lt;br/&gt;&lt;br&gt; distance of the hip joint were performed prior to these pressure measurements. No correlation was found between pain and intracapsular pressure in these OA hips. However, there was an inverse correlation&lt;br/&gt;&lt;br&gt; between radiographic severity of OA and elasticity of the hip joint capsule. These findings indicate an increase in intracapsular pressure in early stages of OA and lower or no pressure in late OA. This observed lack of pain/pressure correlation was not in accordance with previous reports. These measurements were performed after the release of the short rotators. To investigate the effect of the short rotators on intracapsular pressure we investigated the pressure, pain and radiographic grade in OA patients. The pressure was measured in various positions of the hip before and after release of the short rotators. Release of the short rotators did&lt;br/&gt;&lt;br&gt; not change the intracapsular pressure in any position&lt;br/&gt;&lt;br&gt; except in 45° flexion, in which the pressure increased, nor did we find any correlation between pain and intracapsular pressure.&lt;br/&gt;&lt;br&gt; Dislocation after THA is one of the most common postoperative complications. Postoperative intraarticular edema and/or fluid might be&lt;br/&gt;&lt;br&gt; contributing factors. Posterior soft tissue repair was suggested to reduce the dislocation rate and decrease the volume of postoperative fluid in the&lt;br/&gt;&lt;br&gt; THA hip. THA patients with or without posterior soft tissue repair were analyzed. To evaluate postoperative capsular distension, indicating synovial&lt;br/&gt;&lt;br&gt; edema/fluid, US was performed 6 and 12 months after surgery. Posterior soft tissue repair resulted in greater sonographically measured capsular distance&lt;br/&gt;&lt;br&gt; 6 months postoperatively, but after 12 months there was no difference in hips with or without posterior soft tissue repair. This finding suggests that the previously postulated idea that posterior soft tissue repair reduces postoperative “dead space can be debated.&lt;br/&gt;&lt;br&gt; The role of synovitis and increased intracapsular hydrostatic pressure in the loosening process after THA has gained increased attention. Unrevised,&lt;br/&gt;&lt;br&gt; radiographically stable hips that had THA because of osteoarthritis 10 years earlier with 28 or 32 mm femoral heads were analyzed. The correlation&lt;br/&gt;&lt;br&gt; between PE wear and sonographically measured capsular distances was estimated. It was found that 32 mm femoral heads were associated with greater wear and greater capsular distance as compared to 28 mm heads. A correlation between linear and volumetric wear and sonographically measured&lt;br/&gt;&lt;br&gt; capsular distance was also noted. These findings were observed before radiographic signs of loosening, and indicate that the THA loosening process&lt;br/&gt;&lt;br&gt; starts before its radiographic appearance.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f55d9f4c-d942-4191-a13a-81de3834f6a8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="ST_Kappa_090505.pdf">https://portal.research.lu.se/files/3249413/1393192.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2814343</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>total hip replacement</topic> <topic>intracapsular pressure</topic> <topic>Osteoarthritis</topic> <topic>sonography</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-41-7</identifier> <identifier type="oldLupId">1393163</identifier> <part> <detail type="volume"> <number>2009:53</number> </detail> <extent unit="pages"> <total>88</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-26T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f55d9f4c-d942-4191-a13a-81de3834f6a8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:30+02:00</recordDateApproved> </recordInfo> </mods>

Results from the Malmö Diet and Cancer (MDC) cohort indicate lower breast cancer risk at high fiber intake. Folate intake may partly explain this association. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Aims of this thesis were to examine if intakes or plasma concentrations of folate are associated with postmenopausal breast cancer risk, and if associations depend on genetic variation of the folate metabolizing enzyme methylenetetrahydrofolate reductase (MTHFR) or estrogen receptor α and β expression of tumors.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Food habit information and blood samples were collected 1991-96 from 17 035 women between 45 and 73 years in the MDC study. Until end of 2004, 544 cases of invasive breast cancer were diagnosed.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; High folate intake was associated with lower breast cancer risk. The MTHFR 677T allele was associated with increased risk. Among women with this allele, the risk increased with higher intakes and plasma concentrations of folate, and was especially pronounced for folate supplement consumers. Estrogen receptor β negative (ERβ-) breast cancer increased with higher plasma folate concentrations independently of 677C&amp;gt;T genotype.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The results encourage consumption of folate rich foods. However, since women with disturbed folate metabolism due to genetic predisposition may respond differently to high intakes, and high folate status may promote development of ERβ- tumors, folate supplements should be cautiously recommended. The results also contribute knowledge to current discussions regarding mandatory folate fortification of foods.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Folat är ett B-vitamin som kan bidra till minskad risk för en rad sjukdomar, däribland en speciell form av blodbrist, ryggmärgsbråck hos nyfödda, hjärt- kärlsjukdom och vissa cancerformer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Folat förekommer framför allt i många vegetabiliska livsmedel. Speciellt höga halter har gröna bladgrönsaker, baljväxter (t.ex. kikärtor) och lever. Betydande folatkällor i svensk kost är också frukt och grovt bröd.&lt;br/&gt;&lt;br&gt; Dessutom innehåller många kosttillskott den syntetiska formen av folat, som kallas folsyra. Kost rik på frukt, grönsaker och fullkornsprodukter har kopplats till bättre hälsa. Det är dock oklart vilka kostkomponenter som skyddar mot, eller har störst betydelse för utveckling av olika sjukdomar. Kost med stor andel vegetabilier är rik på vitaminer, mineraler och andra bioaktiva ämnen som på olika sätt samverkar med varandra. Det kan därför vara svårt att avgöra vilken roll ett speciellt näringsämne har. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Man uppskattar att var tionde kvinna i Sverige kommer att få bröstcancer under sin livstid. Teoretiskt sett skulle folat kunna påverka insjuknande i bröstcancer. Folat verkar genom att överföra kolfragment till olika kemiska reaktioner i kroppen. Folat har därigenom en viktig roll vid cellbildning, eftersom det kan påverka uppbyggnaden av intakt DNA. Dessutom kan tillgången på folat påverka hur information i våra gener översätts till olika cellstrukturer som kan stimulera respektive hämma tumörutveckling (t.ex. tumörsupressorer). Studier som undersökt samband mellan intag respektive blodnivåer av folat och bröstcancer är dock inte samstämmiga.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I undersökningen Malmö Kost Cancer har man sett att kvinnor med högt fiberintag har lägre risk för bröstcancer. Eftersom kostfibrer kommer från vegetabiliska livsmedel, skulle detta samband delvis kunna bero på andra verksamma ämnen i vegetabilier, t.ex. folat. Syftet med denna avhandling har varit att bland kvinnor som deltog i Malmö Kost Cancer undersöka sambandet mellan kostens innehåll av folat och risken att insjukna i bröstcancer efter klimakteriet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I Malmö Kost Cancer samlade man i början på 1990-talet in information om 28 098 malmöbors matvanor och livsstil. Dessutom samlade man in blodprover samt mätte och vägde deltagarna. Fyrtio procent av alla malmöbor mellan 45 och 73 år deltog i studien. Totalt deltog 17 035 kvinnor. Det är få studier i världen som samlat in så detaljerad information om matvanor. Deltagarna fick föra dagbok över lagade måltider och sin konsumtion av vitamintabletter under en vecka, samt fylla i omfattande formulär om sina matvanor. Därefter fick de svara på frågor om sina matvanor i en 45 minuter lång intervju. Vi följde kvinnorna till slutet av 2004, då 544 hade insjuknat i bröstcancer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Förutsättningarna för att undersöka sambandet mellan folatintag och bröstcancer bland kvinnor som deltog i Malmö Kost Cancer är mycket goda. Först och främst är informationen om kvinnornas folatintag från mat av hög kvalitet och det finns även information om folatintag från vitamintabletter samt om intag av andra B-vitaminer som kan påverka hur folat utnyttjas i kroppen. Dessutom är de insamlade blodproverna värdefulla som komplement till uppgifterna om matvanor, då det är svårt att i detalj lämna uppgifter om kostvanor. Folatnivån i blod är en mer objektiv markör, även om den inte exakt speglar folatintaget. En annan fördel är att det funnits möjlighet att analysera DNA. I stället för att bara undersöka sjukdomsrisk hos personer som får i sig olika mycket folat från kosten, kan man studera sjukdomsrisk hos personer med förändringar i generna som påverkar hur folat utnyttjas i kroppen. På så sätt kommer man ifrån problem med att de som äter mycket frukt och grönsaker också får i sig andra ämnen, som kan ha betydelse för cancerutveckling och göra det svårt att avgöra om folat i sig har någon effekt. Det finns genetiska varianter av det folatomvandlande enzymet metylentetrahydrofolatreduktas (MTHFR), som är kopplade till nedsatt enzymfunktion. Dessa genetiska varianter kan därmed påverka hur folat från kosten kan användas i kroppen. Folatintagets betydelse för bröstcanceruppkomst skulle därför kunna skilja sig mellan kvinnor med eller utan de genetiska varianterna. Slutligen finns det många olika typer av bröstcancer, vars uppkomst kan påverkas av olika kostfaktorer. Ett exempel är bröstcancer med höga eller låga halter av receptorer som tar emot signaler från det kvinnliga könshormonet östrogen. Det finns två typer av östrogenreceptorer, alfa och beta. Tumörer med höga halter av alfareceptorn stimuleras av östrogen och behandlas därför med ämnen som konkurrerar med östrogen om att binda till alfareceptorn. Betareceptorn är mindre utforskad, men verkar vanlig i normala bröstceller, medan förekomsten är lägre i tumörer. Betareceptorn har föreslagits verka som en tumörsuppressor och därmed hämma tumörutveckling. Vi hade information om förekomsten av dessa receptorer i brösttumörer och kunde därmed undersöka om folat var starkare kopplat till någon av dessa tumörtyper. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi fann att de kvinnor vars intag av folat motsvarade det rekommenderade intaget i Sverige endast hade hälften så stor risk att drabbas av bröstcancer jämfört med dem som hade lägst intag av folat, men vars intag av andra B-vitaminer och fibrer inte skilde sig. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Över hälften av kvinnorna var bärare av den genetiska varianten MTHFR 677T, som påverkar hur folat kan användas i kroppen. Dessa kvinnor hade ökad risk för bröstcancer. De kvinnor som hade den genetiska varianten, och samtidigt hade en folatrik kost eller höga folatnivåer i blodet, löpte ännu större risk att drabbas av bröstcancer. Denna riskökning var speciellt uttalad i samband med intag av vitamintabletter med folsyra. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Höga blodnivåer av folat var också kopplade till ökad risk för brösttumörer med låg koncentration av östrogenreceptor beta. Detta samband sågs hos alla kvinnor och verkade inte påverkas av de undersökta varianterna i MTHFR-genen. Det är möjligt att höga folatnivåer medverkar till att stänga av genen som kodar för östrogenreceptor beta. Färre receptorer tar då emot signaler som kanske skulle kunna bromsa tumörutvecklingen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis stödjer resultaten från denna avhandling rekommendationer om folatrik kost med mycket frukt, grönsaker, baljväxter och fullkornsprodukter. Folat verkar dock ha en komplicerad roll i samband med bröstcancerutveckling. På grund av ärftlighet kan till exempel vissa individer ha försämrad förmåga att på bästa sätt utnyttja stora mängder folat. Dessutom verkar höga blodnivåer vara kopplade till ökad risk att utveckla brösttumörer med låg förekomst av östrogenreceptor beta. Dessa resultat kan bidra som underlag i den diskussion som pågår i många länder angående obligatorisk folatberikning av livsmedel. I nuvarande läge bör högre doser av folat, i form av vitamintabletter, bara rekommenderas till grupper eller individer med ökat folatbehov.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/aa68edca-a696-4436-aac4-f3c0e0e9d539</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa100305mall.pdf">https://portal.research.lu.se/files/3249540/2203129.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">558756</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Nutrition Epidemiology Research Group</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>folate</topic> <topic>B-vitamins</topic> <topic>breast cancer</topic> <topic>diet</topic> <topic>epidemiology</topic> <topic>nutrition</topic> <topic>plasma</topic> <topic>polymorphism</topic> <topic>estrogen receptor α</topic> <topic>estrogen receptor β</topic> <topic>reproducibility</topic> <topic>prospective</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-52-8</identifier> <identifier type="oldLupId">2203124</identifier> <part> <detail type="volume"> <number>2010:37</number> </detail> <extent unit="pages"> <total>160</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-04-10T09:30:00+02:00</dateOther> <recordInfo> <recordIdentifier>aa68edca-a696-4436-aac4-f3c0e0e9d539</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:33+02:00</recordDateApproved> </recordInfo> </mods>

These verbs are generally analyzed as accomplishments, achievements and activities which can but need not be combined with a result predicate. They describe either the coming about of a change, the creation/destruction or the obtaining of an object.&lt;br/&gt;In generative syntactic analyses both the subcategorized and the free beneficiary and possessor datives are usually treated the same (with few exceptions): either as arguments of a layered VP-structure, adjuncts or arguments of applicative heads. Even their case is often considered to be licensed in the same way. There are suggestions that these dative DPs bear either structural, oblique or inherent case.&lt;br/&gt;Within cognitive and construction grammar approaches to ditransitive constructions researchers often use the concept of established possession for both the prototypical ditransitive and the beneficiary ditransitive construction. While this is fine for the former, it cannot capture the ambiguity of constructions with beneficiary and possessor datives in German. I propose that this ambiguity arises due to the possibility to change the point of view on the action denoted by the verb.&lt;br/&gt;In my proposal the dative participant is related to the concept of the causal chain by Langacker (1987, 1991) in two different ways. While selected datives are part of the inherent event structure of ditransitive verbs, free datives relate to the event structure of the verb from “outside”. This gives rise to their interpretation as being affected by the event.&lt;br/&gt;Within the framework of the neo-constructionist First-Phase Syntax (Ramchand 2008) I assume that possessor datives and free beneficiary datives when interpreted as affectees are arguments of an applicative head which is inserted above the process denoting phrase in this model. As for the recipient reading in the presence of creation/destruction verbs and verbs of obtaining, the free dative is not part of the verbal event structure but can be involved in a prospective subsequent event.&lt;br/&gt;Since prospectivity even is possible not only with free datives but also with not obligatorily expressed selected datives I investigate the question if there might be a difference in the syntactic licensing of the two types of datives. I show that they do not differ in their structural licensing but could be treated as arguments of resultative predicates with different categorial labeling. They bear inherent case and are inserted in a phrase right beneath the process denoting phrase of the layered decomposition frame in Ramchand’s model.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5d5f61a4-5efe-484f-aaf9-460b7d8b0921</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Abhandlung_Edith_Ekberg.pdf">https://portal.research.lu.se/files/3249704/2303000.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1165496</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">ger</languageTerm> </language> <subject> <topic>action chain</topic> <topic>construction grammar</topic> <topic>structural licensing</topic> <topic>case</topic> <topic>inalienable possession</topic> <topic>possessor dative</topic> <topic>beneficiary dative</topic> <topic>Keywords: ditransitive construction</topic> <topic>free vs. selected indirect objects</topic> <topic>lexical vs. constructional profiling</topic> <topic>event structure</topic> <topic>First-Phase Syntax</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lunder germanistische Forschungen</title> </titleInfo> <identifier type="issn">0348-2146</identifier> <identifier type="isbn">978-91-7473-265-8</identifier> <identifier type="oldLupId">2302983</identifier> <part> <detail type="volume"> <number>72</number> </detail> <extent unit="pages"> <total>319</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-02-25T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>5d5f61a4-5efe-484f-aaf9-460b7d8b0921</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:37+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:37+02:00</recordDateApproved> </recordInfo> </mods>

They are created from the interaction of atoms with ultrashort, intense laser pulses whose electric field approaches the strength of inner-atomic electric fields. This thesis presents experiments around the generation, characterization and application of attosecond pulses.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; First, we study the influence of the atomic generation medium on the temporal properties of attosecond pulses. Their central photon energy can be controlled by using a two-color generation field and by thin-foil filtering techniques tailored to specific spectral bands. With these techniques, broadband attosecond pulses with durations down to 130 as have been measured. To characterize attosecond pulse trains at their birth, we introduce a new method that perturbs the generation laser field with its weak second harmonic. This allows us to assess the influence of the medium in the generation process. We then test the limits of a well-established pulse train characterization method with regard to probe intensity and demonstrate a way to circumvent these&lt;br/&gt;&lt;br&gt; limitations.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A second set of experiments uses attosecond pulses to excite atoms and molecules for the creation of ultrashort wave packets. Free electron wave packets can be controlled by an external laser field and driven to scatter off their parent ions. They also carry information on the atomic structure, which enables the phase-resolved characterization of unknown bound wave packets. Exposing molecules to attosecond pulses can trigger dissociation reactions that can be controlled by a delayed probe laser pulse. We present a study of different probe pulse properties and report the observation of attosecond electron dynamics inside a hydrogen molecule.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/196f054d-40fd-4db8-9cf8-fca5909a0266</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis_MS.pdf">https://portal.research.lu.se/files/3249725/1545438.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">21623604</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Physics, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Molecular dissociation</topic> <topic>Electron wave packets</topic> <topic>Pulse characterization</topic> <topic>Two-color harmonic generation</topic> <topic>Attosecond pulse trains</topic> <topic>Single attosecond pulses</topic> <topic>Resonant two-photon ionization</topic> <topic>Fysicumarkivet A:2010:Swoboda</topic> </subject> <subject authority="lup"> <topic>Atom and Molecular Physics and Optics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Reports on Atomic Physics</title> </titleInfo> <identifier type="issn">0281-2762</identifier> <identifier type="oldLupId">1545435</identifier> <part> <detail type="volume"> <number>414</number> </detail> <extent unit="pages"> <total>202</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-03-19T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>196f054d-40fd-4db8-9cf8-fca5909a0266</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:37+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:37+02:00</recordDateApproved> </recordInfo> </mods>

The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP.&lt;br/&gt;&lt;br&gt; Methods: Prospective, randomised, clinical studies. ASA І and II abdominal surgery patients were randomly assigned to be ventilated with normal VT (NVT) with and without PEEP to 10 cmH2O or with increased VT (IVT) achieved by increasing inspired plateau pressure 0.04 cm H2O kg-1. Extra apparatus dead space was added to maintain PETCO2 at 4.5 kPa. Arterial oxygenation, sevoflurane tension (Pasevo, Fisevo, PETsevo), PaCO2, PETCO2, stroke volume, cardiac output, VT and airway pressure were measured.&lt;br/&gt;&lt;br&gt; Results: The groups of patients compared were similar regarding gender, age, and BMI. Arterial oxygen and sevoflurane tension was generally higher in the IVT group (P &amp;lt; 0.05) whereas mean FiO2 and PETsevo did not differ between the groups. Arterial carbon dioxide was significantly lower with IVT than NVT ventilated without PEEP but in the presence of PEEP in the NVT group, the groups were similar. Cardiac output decreased significantly less in the IVT group compared to the NVT group with PEEP (5 and 33 % respectively).&lt;br/&gt;&lt;br&gt; Conclusion: Isocapnic ventilation with larger tidal volumes maintained with added apparatus dead-space increases the arterial oxygen and sevoflurane tension as well as carbon dioxide elimination in normal and overweight patients, and in overweight patient also preserves cardiac output better than in the presence of PEEP.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Intubationer (nedsättande av andningsslang i luftstrupen) i samband med generella anestesier kan påverka lungfunktionen med en sänkt arteriell syresättning (SpO2) som följd. Medel för inhalationsanestesi administreras och elimineras via andningsvägarna. Anestesimedlen tas upp i blodet från lungans alveoler genom diffusion och transporteras löst i blodplasma till hjärnan där effekten för anestesi uppkommer. Lösligheten i blod för de olika anestesimedlen är den faktor som inverkar mest på den initiala farmakokinetiken. Ju lägre lösligheten för ett anestesimedel är desto fortare kommer den alveolara koncentrationen att stiga och omvänt för de lösligare anestesimedlen. Den initiala alveolara koncentrationsstegringen bestäms av den funktionella residualkapaciteten (FRC) i lungorna, den alveolara ventilationens (VA) storlek samt den inspiriatoriska koncentrationen. När gaskoncentrationen stiger i alveolerna kommer ytterligare stegring av koncentrationen i stor utsträckning att styras av upptaget i blodplasman som avgörs av storleken på hjärtminutvolymen och lösligheten i blod.&lt;br/&gt;&lt;br&gt; Faktorer som påverkar FRC negativt är lägesförändringen av patienten från ett sittande/stående läge till liggande, detta reducerar FRC med en volym av 0,8-1,0 liter. Vid en anestesiinduktion försämras FRC ytterligare med en volym av 0,4-0,5 liter, detta genom att anestesifarmaka påverkar bröstkorgens muskeltonus och diafragmavalvet får en förskjutning mot bröstkorgen. Sänkta FRC volymer minskar avståndet till lungornas residualvolym, detta gör att luftvägsavstängningar inträffar lättare vid små lungvolymer. Luftvägsavstängningar är en trolig förklaring till de regioner med en låg ventilations - perfusionskvot (låg VA/Q) som uppstår under en anestesi. Intubationen minskar den naturliga del av luftvägarna som inte deltar i patientens gasutbyte (fysiologiskt dead-space) och minskar därigenom lungornas fysiologiska residual kapacitet (FRC), vilken utgör en viktig del av lungornas syrgasreserv. Andra troliga orsaker till sänkt SpO2 under narkos är sammanfallen lungvävnad (atelektaser). Detta innebär en ytterligare förlust av funktionell lungvävnad och reduktion av FRC, vilket sammantaget även anses orsaka en omfördelning av blod ifrån patientens bröstkorg. Kraftigt överviktiga personer har ett FRC och en expiratorisk reserv volym (ERV) som är reducerat vilket ytterligare förvärras vid ett liggande kroppsläge och under en anestesi. &lt;br/&gt;&lt;br&gt; Med denna kunskap som underlag har vi undersökt hur större andetagsvolymer (tidalvolymer), kan förbättra patientens SpO2 under generell anestesi. För att kunna ventilera patienterna med större andetag utan att koldioxidhalten I blodet blir för låg måste patienterna återandas en del av andetaget (dead-space andning). I de olika studierna var patienterna i de olika grupperna normal- eller överviktiga. I ventilationsmönstret på narkosapparaten ställdes in så att patientgrupperna antingen fick stora andetagsvolymer med inget positivt slut-ut-andningstryck (PEEP) eller normala andetagsvolymer med eller utan PEEP. Patienterna i de olika grupperna av normalventilerade patienter utan tillägg av dead-space och andetagsvolymer, utan PEEP (studie 1-3) eller med PEEP (studie 4) där, patienten erhöll ett PEEP på10 cmH2O. I de olika grupperna med förstorade andningsvolymer, erhåller patienterna extra dead-space volymer, placerat mellan anestesiapparatens slangsystem och patientens trachealtub (slang placerad i luftstrupen) och större andetagsvolym. Specifik dead-space volym för varje patient genereras ur använd ventilationsmetod. Ventilationsmetoden innebär ventilation av patienterna med tidalvolymer stora nog att generera ett paustryck i lungorna (sluttryck i alveolerna), på 0.04 cmH2O kg-1 över initialt paustryck uppmätt i ventilatorn.&lt;br/&gt;&lt;br&gt; Resultatet som studien visade var ett måttligt högre SpO2 och en minskad skillnad mellan blodets koldioxid tryck (PaCO2) och det utandande koldioxid halten (PETCO2) i den grupp som hade de större andetagen/minut-volymerna med apparat dead-space (Studie 1).&lt;br/&gt;&lt;br&gt; Vi har även undersökt om större tidalvolymer, genom ökad dead-space ventilation på intuberade patienter under generell anestesi åstadkommer en förändring av relationen mellan inställd mängd syrgas/sevofluran och den pulmonella/arteriella halten syrgas/sevofluran hos normal- eller överviktiga patienterna (Studie 2-3). Resultatet av dessa studier visade att det finns, en ökad blodkoncentration sevofluran i gruppen med de större andetagsvolymerna med en extra dead-space volym. Dessa studier med en ökad ventilation med ett extra dead-space volym har kunnat visa på en positiv ökning av inflödet av anestesimedlet sevofluran in i blodet och en förbättrad syresättning av patienter med större andetagsvolymerna. &lt;br/&gt;&lt;br&gt; I studie 4 fann vi att större tidalvolymer jämfört med normala tidalvolymer med ett tillägg av PEEP på 10 cmH2O, gav ett ökat upptag av blodkoncentration sevofluran i gruppen med de större andetagsvolymerna med en extra dead-space volym samt en mindre sänkning av hjärtminutvolymen jämfört med den gruppen av patienter som var normalventilerade med ett tillägg av PEEP. Ett resultat som studie 4 också gav var att ventilation med större tidalvolymer gav ett lägre paus- och medeltryck I lungorna jämfört med PEEP gruppen vid anestesi av överviktiga patienter. Ventilation med större tidalvolymer skulle alltså kunna medföra en större cirkulatorisk stabilitet genom en mindre sänkt hjärtminutvolym och en mindre risk för att få en tryckrelaterad lungskada.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/bdd6c607-d2d3-4a15-8cd3-5dc7000343e3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Bruno_E_elektronisk_spik_2_.pdf">https://portal.research.lu.se/files/3249772/1895096.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">902764</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Anaesthesiology and Intensive Care, Lund</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>anaesthesia</topic> <topic>sevoflurane</topic> <topic>cardiac output</topic> <topic>functional residual capacity</topic> <topic>pulmonary gas exchange</topic> </subject> <subject authority="lup"> <topic>Anesthesiology and Intensive Care</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-04-8</identifier> <identifier type="oldLupId">1895061</identifier> <part> <detail type="volume"> <number>2011: 55</number> </detail> <extent unit="pages"> <total>76</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-06-01T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>bdd6c607-d2d3-4a15-8cd3-5dc7000343e3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:39+02:00</recordDateApproved> </recordInfo> </mods>

It can also be analyzed from the perspective of a continuum starting from the report to the social authorities, the evaluations on whether to commit or not, the actual commitment and aftercare following involuntary treatment. Enhancing knowledge on the total process of commitment requires intense research studies with an application of a wide array of research methods. This thesis includes interviews, assessments and a randomised trial performed in the different stages of court-ordered care of patients with substance abuse; evaluation, decision to petition the court for commitment, the commitment, the care at an involuntary institution and aftercare. We interviewed 74 patients about their experiences of evaluation and the patients reported initial feelings of anger and violation and only half of the group had any contact with the social worker in charge of the case. Of the interviewed patients, 35 had previous experience of commitment. They were satisfied with the care at the institution and felt that they could influence the care even though a majority of the patients also reported that coercive measures had been applied during care. The patients though, were not satisfied with the contact with the social worker while planning aftercare and few plans were carried through. We explored the decision by the social welfare board to petition the court for commitment by having experts assessed 106 cases that the board previously had made decisions about. The comparison between the boards’ decisions and the experts’ assessments revealed that there was an association between patients’ social variables and the board’s decision contrary to the experts’ assessment that showed no such association. This could create a legal uncertainty about the boards’ application of the legal criteria. Prior to an amendment of the involuntary legislation, the difference between municipalities in rate of petitions was very small. After the responsibility to petition the court for commitment was transferred from central authority to local authority, differences emerged. We contrasted two municipalities with high rate (55%) and two with low rate (12%) in order to measure global outcome two years after evaluation, but found no significant difference in regard to substance abuse, housing and means of support between the evaluated patients from the two types of municipalities. Seven patients had deceased during two years after evaluation, none of the deceased patients had been committed. Finally, case management was used as an intervention in aftercare following commitment and 36 patients were randomised to either case management or treatment-as-usual. The patients in the case manager group seem to have retained their abstinence in a higher degree than the patients in the control group. Despite the fact that one of the core components of case management is to link to care, the use of care did not differ between groups. Patients with a continued severe substance abuse had significantly more contact with in-patient care and social services, while abstinent patients had less contact with care and service. The study involved eleven municipalities and three involuntary institutions and the research design, instruments and intervention was well received by patients as well as participating units. The study had to end prematurly due to few committed patients and needs to be replicated with a larger population.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8c68b2fa-813a-4790-9348-d203a3dec95a</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Court-order</topic> <topic>commitment</topic> <topic>involuntary care</topic> <topic>substance abuse</topic> <topic>legal criteria</topic> <topic>randomised trial</topic> <topic>mortality</topic> <topic>case management.</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-47-5</identifier> <identifier type="oldLupId">2195386</identifier> <part> <detail type="volume"> <number>2011:98</number> </detail> <extent unit="pages"> <total>128</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-11-11T10:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>8c68b2fa-813a-4790-9348-d203a3dec95a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:43+02:00</recordDateApproved> </recordInfo> </mods>

One of the key players in fibrosis is the fibroblast and its progenitor, the fibrocyte. The fibroblast is the main producer of extracellular matrix molecules such as collagen, versican, perlecan, biglycan, and decorin. Fibrocytes are recruited from the bone marrow to the site of injury. It is possible that the stromal cell-derived factor-1/CXCL12 builds up in a gradient to recruit CXCR4 expressing fibrocytes, at least in the case of idiopathic pulmonary fibrosis. Patients with obliterative bronchilitis have an enlarged vessel lumen and a larger endothelial layer area, which has been shown to be correlated to more fibrocytes in the tissue. A correlation was found between the numbers of fibrocytes identified in tissue and structural changes in the lung. In idiopathic pulmonary fibrosis, a correlation was found between numbers of fibrocytes and numbers of fibroblastic foci, and in patients with obliterative bronchiolitis there was a correlation between fibrocyte numbers and thickening of the alveolar parenchyma. Eventually the fibrocyte enters the tissue and can differentiate into a fibroblast.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Matrix production by fibroblasts in patients who have undergone lung transplantation and in asthmatic subjects involves both the central and the distal parts of the lung. In lung-transplanted patients, the production of proteoglycans in the distal part was found to be double that in the central part. Versican production was particularly elevated compared to controls. The production of proteoglycans was further correlated with proliferation rate. A common feature of fibroblasts in patients after lung transplantation and asthmatic subjects was that these cells proliferated more slowly than in control subjects. Distally-derived fibroblasts from asthmatic subjects produced more veriscan, were immobile, and had many protrusions. The distal parts of the lungs were also rich in collagen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A better understanding of fibrocyte and fibroblast function will help us to characterise the mechanisms behind idiopathic pulmonary disease, asthma, obliterative bronchiolitis. This knowledge can then be applied to other types of fibrotic disorders.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/62c14d92-a2af-4f2c-8f7a-9a7954239c4f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Annika_final_G5_kappa.pdf">https://portal.research.lu.se/files/3250141/1503899.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2135473</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-11-5</identifier> <identifier type="oldLupId">1503898</identifier> <part> <detail type="volume"> <number>2009:122</number> </detail> <extent unit="pages"> <total>80</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-12-11T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>62c14d92-a2af-4f2c-8f7a-9a7954239c4f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:47+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:05:11Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:47+02:00</recordDateApproved> </recordInfo> </mods>

The critical task of the cell cycle is to ensure that DNA is faithfully replicated and that identical chromosomal copies are distributed equally to two daughter cells during mitosis with the help of the mitotic spindle. Thus, mitotic spindle formation is vital for proper chromosome congression, alignment and segregation during cell division. Dysregulation of any of the components involved in this process may cause mis-segregation of the chromosomes and chromosomal instability, which are commonly observed in cancer. There are a number of surveillance mechanisms to ensure errors are corrected, and if not, the cells commit suicide (apoptosis). In cancer, this tightly regulated process malfunctions as a result of genetic mutations, resulting in uncontrolled cell proliferation. &lt;br/&gt;&lt;br&gt; g-Tubulin is a member of the tubulin family that is required for interphase αβ-tubulin nucleation, spindle formation and centrosomal duplication. The cell cycle is a closely controlled process, involving multiple components with regulation on several levels. The findings from our studies suggest that at the G1/S-phase transition, when retinoblastoma protein (RB) releases E2 promoter binding factors (E2Fs), g-tubulin associates with and captures E2F to ensure a transient transcription of genes necessary for S-phase entry. In addition, we found that the g-tubulin deubiquitination enzyme, BRCA1 Associated Protein 1 (BAP1), was downregulated in metastatic adenocarcinoma breast cell lines compared to non-cancerous human breast epithelial cells. Reduced expression of BAP1 in breast cancer cell lines was associated with mitotic abnormalities. Rescue experiments involving expression of BAP1 reduced ubiquitination of g-tubulin and prevented mitotic defects. Furthermore, we found that the tumour suppressor function of BAP1 in neuroblastoma is mediated through the arrest of cells in S phase, and further, it promoted cell death. In conclusion, our studies define important functions of g-tubulin and BAP1 in the regulation of the cell cycle and proper segregation of the chromosomes.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2b6d9407-d862-4220-a168-01b632237089</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Zarrizi-Thesis_20150417_REF1-4.pdf">https://portal.research.lu.se/files/3256763/5365067.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1793539</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Translational Cancer Research</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-146-0</identifier> <identifier type="oldLupId">5364894</identifier> <part> <detail type="volume"> <number>2015:67</number> </detail> <extent unit="pages"> <total>49</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-27T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>2b6d9407-d862-4220-a168-01b632237089</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:14:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:14:58+02:00</recordDateApproved> </recordInfo> </mods>

Laminin α2 chain is associated to the muscle fibers by two major receptors, where one of them, integrin α7β1, is diminished upon laminin α2 chain deficiency.&lt;br/&gt;&lt;br&gt; The majority of the skeletal muscles display severe dystrophic phenotypes upon laminin α2 chain absence, but we report a spared muscle group, the intrinsic laryngeal muscles (ILM). No evidence of muscle degeneration is detected and expression of various laminin chains is similar to that of limb muscles but sustained integrin α7B expression is noted. We therefore conclude that ILM are spared in the dy3K/dy3K mouse model of congenital muscular dystrophy type 1A.&lt;br/&gt;&lt;br&gt; The singling mediated by laminin α2 chain is poorly understood. To gain insight into the molecular mechanisms underlying MDC1A, we have performed gene expression profiling of laminin α2 chain deficient mouse limb muscle. One of the down-regulated genes encodes a protein called calcium and integrin binding protein 2 (Cib2) whose expression and function is unknown. However, the closely related Cib1 has been reported to bind integrin αIIb and may be involved in outside-in-signaling in platelets. Since Cib2 might be a novel integrin α7β1 binding protein in muscle, we have studied Cib2 expression in the developing and adult mouse. We demonstrate that Cib2 is a calcium binding protein that interacts with integrin α7Bβ1D. Thus, our data suggest a role for Cib2 as a cytoplasmic effector of integrin α7Bβ1D signaling in skeletal muscle.&lt;br/&gt;&lt;br&gt; Moreover, we have in the seminiferous tubules of laminin α2 chain deficient mice observed a defect in the timing of lumen formation, resulting in production of fewer spermatides. We also demonstrate that overexpression of laminin α1 chain in testis of dy3K/dy3K mice compensated for laminin α2 chain deficiency and significantly reversed the appearance of the histopathological features. We thus provide genetic data that laminin α chains are essential for normal testicular function in vivo.&lt;br/&gt;&lt;br&gt; In summary, the increased knowledge about the roles of laminin α2 chain in development and disease will hopefully help us to design novel therapeutic approaches for MDC1A.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/55defdd7-4c42-4196-a215-a170749d8d93</url> </location> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-97-86059-41-5</identifier> <identifier type="oldLupId">1221740</identifier> <part> <detail type="volume"> <number>2008:88</number> </detail> <extent unit="pages"> <total>62</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-09-26T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>55defdd7-4c42-4196-a215-a170749d8d93</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:15:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:15:11+02:00</recordDateApproved> </recordInfo> </mods>

The results indicated that difference between individuals with high and low biomarker values at the baseline was diminishing over time.&lt;br/&gt;&lt;br&gt; In paper II, we estimated and validated the risk equations for the first and second major macrovascular events after diagnosis during the five years of follow up using the data on 29,034 T2DM patients from the NDR. We used the Weibull proportional hazard regression to estimate these equations. We found within- and between-event heterogeneities in associations between explanatory variables and the risk of experiencing an event. Validation analysis indicated that all equations had reasonable predictive accuracy in the test sample.&lt;br/&gt;&lt;br&gt; In paper III, health utility weights associated with several T2DM-related complications were estimated using survey data on the Swedish version of EuroQol (EQ-5D) instrument among 1,757 T2DM patients collected by the NDR in 2008. The results indicated that history of kidney disorders (–0.114) and stroke (–0.111) had the highest negative effects on the UK EQ-5D index score. Using the UK and Swedish tariffs resulted in discrepant estimates, possibly leading to divergent results from cost–utility analyses.&lt;br/&gt;&lt;br&gt; In paper IV, an existing cohort model of T2DM in Sweden was updated using equations from papers II and III, and was used to estimate the lifetime costs and benefits of three second-line treatment alternatives, i.e., GLP-1 agonists, DPP-4 inhibitors, or NPH insulin, as add-on to metformin among T2DM patients in Sweden failing to reach Hba1c ≤ 7% with metformin alone. The results indicated that assuming a willingness to pay of SEK 500,000 per QALY gained in Sweden, treatment strategy with GLP-1 can be considered cost-effective compared to DPP-4 or NPH insulin as second line treatment.&lt;br/&gt;&lt;br&gt; The results indicated the importance of developing and refining the equations required in CSMs as new data become available. The data presented in the current thesis are representative of the current clinical practice in Sweden and hence it is suggested that using these data in economic evaluations of T2DM treatment strategies might provide more relevant and accurate results for policy-making in Sweden.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/be4aa46c-301b-4515-8916-34c6870ff45c</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Aliasghar_AhmadKappa-1.pdf">https://portal.research.lu.se/files/3258058/4580875.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1343370</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Health Economics</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Health Care Service and Management, Health Policy and Services and Health Economy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-021-0</identifier> <identifier type="oldLupId">4580721</identifier> <part> <detail type="volume"> <number>2014:92</number> </detail> <extent unit="pages"> <total>57</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-09-11T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>be4aa46c-301b-4515-8916-34c6870ff45c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:15:17+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:15:17+02:00</recordDateApproved> </recordInfo> </mods>

The aim of this thesis was first to investigate the lifetime prevalence of sexual abuse of varying severity and characteristics as well as the associations between sexual abuse, gender, socio-demographic characteristics and consensual sexual experiences. The next aim was to investigate disclosure rates and disclosure patterns as well as predictors of non-disclosure. A further aim was to study the associations between sexual abuse and different aspects of psychosocial health. One of the measures of psychosocial health used in the study was the Strengths and Difficulties Questionnaire (SDQ) and a further aim of the thesis was to examine its psychometric properties when used with young people at age 17 – 19 years. Finally, it was an aim of this thesis to highlight ethical aspects of research about sexual abuse by investigating vulnerable participants’ experience with the survey.&lt;br/&gt;&lt;br&gt; A school-based sample of more than 4,000 high school seniors in five Swedish towns completed the questionnaire “Adolescents’ Sexuality – Attitudes and Experiences”. The same questionnaire was completed by young people in six other countries as part of The Baltic Sea Regional Study on Adolescents’ Sexuality. Data from both the Swedish and the Estonian sample were used when vulnerable participants’ experience of the survey were examined. A sub-sample of more than 1,000 participants in one of the Swedish towns completed additional questionnaires (SDQ, Sense of Coherence and I think I am).&lt;br/&gt;&lt;br&gt; Lifetime prevalence rates were shown for three different categories of sexual abuse: non-contact abuse, contact abuse and penetrating abuse. Penetrating abuse was related to more severe abuse characteristics, less frequent disclosure, more emotional and behavioural symptoms, weaker sense of coherence and poorer self-esteem when compared to non-abuse, non-contact or contact abuse. A substantial portion of the sexual abuse was committed by peers. At the same time, peers were the most often mentioned recipients of disclosure of sexual abuse. Few sexually exposed adolescents had talked to a professional. The SDQ had acceptable reliability and validity for use with adolescents at age 17 – 19 years. Sense of Coherence was found to be the measure of psychosocial health that was most clearly associated with sexual abuse, even after adjustment for confounding variables. Family factors, in particular parental bonding, were shown to be strongly related to different aspects of sexual abuse. A model of the participants’ experience with the survey did not support the idea that vulnerable young people should be protected from participation in research about sensitive issues.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; SVENSK SAMMANFATTNING&lt;br/&gt;&lt;br&gt; Huvudsyftet med denna avhandling var att undersöka olika aspekter av självrapporterade sexuella övergrepp under barndom och ungdomstid i en befolkningsstudie med svenska gymnasieelever. Ett av målen var att undersöka livstidsprevalensen för olika typer av sexuella övergrepp och olika övergreppsvariabler samt relationen mellan sexuella övergrepp, kön, sociodemografiska variabler och frivilliga sexuella erfarenheter. Ett annat mål var att studera i vilken utsträckning ungdomarna har berättat om övergreppen, vilka mönster som förekommer i samband med berättandet och vilka faktorer som påverkar att ungdomar väljer att inte berätta om övergreppen. Ytterligare ett mål var att studera sambanden mellan sexuella övergrepp och olika aspekter av psykosocial hälsa. Ett av instrumenten för mätning av psykosocial hälsa som har använts i studien var Strengths and Difficulties Questionnaire (SDQ). Ett av avhandlingens mål var att undersöka de psykometriska egenskaperna av instrumentet när det används i åldergruppen 17 till 19 år. Slutligen var en målsättning med avhandlingen att belysa etiska aspekter kring forskning om sexuella övergrepp genom att undersöka särskilt sårbara deltagares upplevelse av att fylla i enkäten.&lt;br/&gt;&lt;br&gt; En skolbaserad undersökningsgrupp bestående av mer än 4000 ungdomar i år 3 på gymnasiet i fem svenska städer fyllde i frågeformuläret ”Ungdomars sexualitet – attityder och erfarenheter”. Samma frågeformulär användes också i flera andra länder inom ramen för The Baltic Sea Regional Study on Adolescents’ Sexuality. Datamaterial från såväl den svenska som den estniska undersökningsgruppen användes vid undersökningen av sårbara deltagares upplevelse av att fylla i enkäten. En delgrupp bestående av med än 1000 deltagare i en av de svenska städerna fyllde i ytterligare frågeformulär (SDQ, KASAM och Jag tycker jag är).&lt;br/&gt;&lt;br&gt; Livstidsprevalensen beräknades för tre olika former av sexuella övergrepp: övergrepp utan fysisk kontakt, övergrepp med fysisk kontakt men utan penetration och penetrerande övergrepp. Penetrerande övergrepp var associerade med de mest allvarliga övergreppsvariablerna. Det var också mindre vanligt att dessa ungdomar berättade om övergreppen och de rapporterade fler emotionella och beteenderelaterade symptom, svagare KASAM och en mer negativ självvärdering vid jämförelse med icke utsatta ungdomar eller ungdomar som hade blivit utsatta för övergrepp utan fysisk kontakt eller övergrepp med fysisk kontakt men utan penetration. I en väsentlig del av övergreppen hade förövaren varit en annan ungdom. Samtidigt nämndes jämnåriga som den vanligaste mottagaren av berättelsen om övergreppet. Få sexuellt utsatta ungdomar hade talat med en professionell vuxen om övergreppen. Instrumentet SDQ hade acceptabel reliabilitet och validitet vid användning i åldergruppen 17 till 19 år. Sense of Coherence var det mätinstrumentet avseende psykosocial hälsa som var starkast relaterad till sexuella övergrepp, även efter kontroll för störfaktorer. Också familjevariabler, i synnerhet band till föräldrarna (parental bonding), var starkt relaterade till olika övergreppsaspekter. En modell för deltagarnas upplevelse av att svara på enkätfrågorna gav inget stöd till tanken att sårbara ungdomar borde skyddas från att delta i forskning om känsliga ämnen som sexualitet och sexuella övergrepp.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e7157e5a-6d07-474d-9915-52abd4086792</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Gisela_Kappa_090420.pdf">https://portal.research.lu.se/files/3261593/1389605.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">630483</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Sense of Coherence</topic> <topic>Research Ethics</topic> <topic>Prevalence</topic> <topic>Health</topic> <topic>Disclosure</topic> <topic>Adolescents</topic> <topic>Characteristics of sexual abuse</topic> <topic>Sexual abuse</topic> </subject> <subject authority="lup"> <topic>Psychiatry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-32-5</identifier> <identifier type="oldLupId">1389603</identifier> <part> <detail type="volume"> <number>2009:44</number> </detail> <extent unit="pages"> <total>202</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-14T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>e7157e5a-6d07-474d-9915-52abd4086792</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:15:25+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:04:02Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:15:25+02:00</recordDateApproved> </recordInfo> </mods>

Passive houses are&lt;br/&gt;&lt;br&gt; one way to reduce the energy use in buildings and at the same time keep&lt;br/&gt;&lt;br&gt; a good indoor comfort. The basic idea of the passive house concept is to&lt;br/&gt;&lt;br&gt; have well insulated and air tight climate shell together with a mechanical&lt;br/&gt;&lt;br&gt; ventilation system. Within this research, four Swedish passive house&lt;br/&gt;&lt;br&gt; projects have been followed from the early planning stage to evaluation&lt;br/&gt;&lt;br&gt; of the actual buildings; three apartment building projects in Värnamo,&lt;br/&gt;&lt;br&gt; Frillesås and Alingsås and one single-family house in Lidköping. Three of&lt;br/&gt;&lt;br&gt; the projects were new built and the fourth, in Alingsås, was a renovation&lt;br/&gt;&lt;br&gt; project. The research was funded by the Swedish Energy Agency and has&lt;br/&gt;&lt;br&gt; been a five year project. The main purpose with the study was to see how&lt;br/&gt;&lt;br&gt; energy efficient residential buildings, mainly passive houses, can be built&lt;br/&gt;&lt;br&gt; in Sweden and on a more widespread scale than before.&lt;br/&gt;&lt;br&gt; The total measured energy use for space heating, domestic hot water&lt;br/&gt;&lt;br&gt; and common electricity was in Värnamo 36 kWh/m2a, in Frillesås 50.5&lt;br/&gt;&lt;br&gt; kWh/m2a, in Alingsås 65.7 kWh/m2a and in Lidköping 51 kWh/m2a,&lt;br/&gt;&lt;br&gt; revised to a normal year. The peak load for space heating is measured to&lt;br/&gt;&lt;br&gt; be somewhat higher than the required 10 W/m2 (12 W/m2 required in&lt;br/&gt;&lt;br&gt; the single family house).&lt;br/&gt;&lt;br&gt; Previous research shows that a ventilation air change rate of 0.5 ach&lt;br/&gt;&lt;br&gt; seems to be necessary in order to achieve a good indoor air quality. Simulations made in this research shows that not much energy is saved by&lt;br/&gt;&lt;br&gt; decreasing the ventilation rate below 0.5 ach and should be avoided to&lt;br/&gt;&lt;br&gt; assure a good indoor comfort.&lt;br/&gt;&lt;br&gt; Some products have been detected to be in need of development to&lt;br/&gt;&lt;br&gt; ease the building of passive houses in the future, e.g. easier used ventilation units, supply air devices suitable for space heating distribution and woodburning stoves with a power to the room of 1 – 3 kW.&lt;br/&gt;&lt;br&gt; There were some additional costs in these demonstration projects for&lt;br/&gt;&lt;br&gt; e.g. education, air-tight solutions and more expensive products which can be decreased in future projects when more suitable products are available&lt;br/&gt;&lt;br&gt; on the market and when the knowledge and experience of how to build&lt;br/&gt;&lt;br&gt; energy effi cient buildings is natural and well spread. The three clients of the apartment buildings have all continued with building new passive&lt;br/&gt;&lt;br&gt; houses or renovating according to the passive house principles after their&lt;br/&gt;&lt;br&gt; demonstration project was finished.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Energianvändningen i världen måste minska drastiskt inom en snar&lt;br/&gt;&lt;br&gt; framtid för att därmed minska utsläppen av växthusgaser och bromsa&lt;br/&gt;&lt;br&gt; klimatförändringarna. Energi och handlande med energikällor har även&lt;br/&gt;&lt;br&gt; blivit nationella säkerhetsfrågor. Inom Europeiska Unionen används ungefär&lt;br/&gt;&lt;br&gt; 40% av den totala energianvändningen i byggnader, vilket innebär&lt;br/&gt;&lt;br&gt; ungefär 36% av det totala koldioxidutsläppet i unionen. Genom att minska&lt;br/&gt;&lt;br&gt; energianvändningen i byggnader kan stora förbättringar uppnås. EU har&lt;br/&gt;&lt;br&gt; nyligen beslutat att år 2020 ska alla byggnader i alla medlemsländer ha&lt;br/&gt;&lt;br&gt; en energianvändning som är nära noll och när byggnader renoveras ska&lt;br/&gt;&lt;br&gt; energiförbättrande åtgärder ingå.&lt;br/&gt;&lt;br&gt; Det är väldigt viktigt att en lägre energianvändning i en byggnad inte&lt;br/&gt;&lt;br&gt; försämrar inomhuskomforten. Ett bra sätt att lyckas med detta är att&lt;br/&gt;&lt;br&gt; bygga passivhus. Grundtanken med passivhus är att göra klimatskalet så&lt;br/&gt;&lt;br&gt; välisolerat och lufttätt att den värme som behövs till huset kan tillföras med den ventilationsluft som ändå behövs. För att minska behovet av tillförd energi värms den inkommande kalla, friska luften av värmen i den utgående varma, begagnade luften i en värmeväxlare. In i huset kommer frisk och värmd tilluft. På vintern behöver tilluften värmas extra med till exempel en vattenburen värmeslinga för att huset ska ha rätt inomhustemperatur.&lt;br/&gt;&lt;br&gt; Att värma med luft är inget måste men det ska vara en möjlighet. Om&lt;br/&gt;&lt;br&gt; byggnaden är konstruerad så att den maximalt behöver 10 – 16 W/m2&lt;br/&gt;&lt;br&gt; för uppvärmning den kallaste dagen är det möjligt att värma med tilluften.&lt;br/&gt;&lt;br&gt; (Jämför med en hårtork som ofta har en effekt runt 2000W!) Detta&lt;br/&gt;&lt;br&gt; motsvarar ett väldigt lågt energibehov för uppvärmning. Genom att ha&lt;br/&gt;&lt;br&gt; en tät byggnad och att tillföra uppvärmd luft minskar också risken för att&lt;br/&gt;&lt;br&gt; uppleva drag inomhus.&lt;br/&gt;&lt;br&gt; I denna forskningsstudie har fyra svenska passivhusprojekt följts från&lt;br/&gt;&lt;br&gt; start till färdig byggnad med det huvudsakliga målet att se hur fler passivhus kan byggas i Sverige. Genom att praktiskt delta i de fyra projekten från start till färdig byggnad med kunskapsstöd, beräkningar och samtal med entreprenörer har kunskap erhållits från alla steg i byggprocessen. Efter att hyresgästerna flyttat in har de blivit intervjuade om hur det är att bo i passivhus. Faktisk energianvändning och inomhustemperaturer har mätts och sammanställts i alla projekten.&lt;br/&gt;&lt;br&gt; Finnvedsbostäders hyresrätter i Värnamo var det första projektet som&lt;br/&gt;&lt;br&gt; färdigställdes; de 40 lägenheterna var klara för inflyttning under sommaren&lt;br/&gt;&lt;br&gt; 2006. Den årliga energianvändningen för värme, varmvatten och&lt;br/&gt;&lt;br&gt; fastighetsel (till exempel fläktar, pumpar och utomhusbelysning) mättes&lt;br/&gt;&lt;br&gt; till 36 kWh/m2a (normalårskorrigerat). Det andra projektet som blev&lt;br/&gt;&lt;br&gt; klart byggdes av Eksta Bostads AB som hyresrätter i Frillesås. Dessa 12&lt;br/&gt;&lt;br&gt; lägenheter hade en årlig mätt energianvändning för värme, varmvatten och&lt;br/&gt;&lt;br&gt; fastighetsel på 50.5 kWh/m2a (normalårskorrigerat). Det tredje projektet&lt;br/&gt;&lt;br&gt; som blev klart var en villa som byggdes i Lidköping. Villan är på 171 m2&lt;br/&gt;&lt;br&gt; och hade en årlig mätt energianvändning för värme och varmvatten på&lt;br/&gt;&lt;br&gt; 51 kWh/m2a (normalårskorrigerat). Enligt gällande regler från Boverket&lt;br/&gt;&lt;br&gt; ska en nybyggd bostad max använda 110 kWh/m2år. De uppmätta resultaten&lt;br/&gt;&lt;br&gt; från dessa projekt visar tydligt att det går att bygga bostäder med&lt;br/&gt;&lt;br&gt; mycket lägre energianvändning, med vanliga snickare, vanliga material&lt;br/&gt;&lt;br&gt; och vanliga hyresgäster.&lt;br/&gt;&lt;br&gt; Det fjärde projektet blev färdigställt i februari 2009 och var en renovering av ett befintligt hyreshus från 1970 med 18 lägenheter (16 lägenheter efter renovering). Energianvändningen efter renovering för värme, varmvatten och fastighetsel var 65.7 kWh/m2a (normalårskorrigerat) eller 86.2 kWh/m2a inklusive hushållsel. Före renovering var energibehovet&lt;br/&gt;&lt;br&gt; 215 kWh/m2a, inklusive hushållsel. Det finns inga regler om hur mycket&lt;br/&gt;&lt;br&gt; energi en renoverad byggnad maximalt får använda efter renovering men&lt;br/&gt;&lt;br&gt; detta resultat visar att det är möjligt att sänka energianvändningen i en&lt;br/&gt;&lt;br&gt; befintlig byggnad med 60%.&lt;br/&gt;&lt;br&gt; Alla fyra projekten har uppnått det initialt satta målet att använda 25&lt;br/&gt;&lt;br&gt; – 50% av tillåten energinivå enligt Boverkets byggregler. Att bygga passivhus verkar vara ett bra sätt att drastiskt minska energianvändningen i samhället, både vid renovering och vid nybyggnad utan att göra avkall på&lt;br/&gt;&lt;br&gt; inomhuskomfort. För att underlätta i framtida projekt skulle det behövas&lt;br/&gt;&lt;br&gt; en produktutveckling av till exempel lättmanövrerade ventilationsaggregat&lt;br/&gt;&lt;br&gt; för småhus, kaminer anpassade för bostäder med lågt uppvärmningsbehov&lt;br/&gt;&lt;br&gt; och estetiskt tilltalande tilluftsdon som fungerar för både höga och låga&lt;br/&gt;&lt;br&gt; fl öden och varierande temperaturer på den luft som blåses in i rummet.&lt;br/&gt;&lt;br&gt; De tre fastighetsägarna till hyreslägenheterna i denna studie har alla&lt;br/&gt;&lt;br&gt; fortsatt att bygga fler passivhus eller renovera enligt passivhusprinciperna, då de varit mycket nöjda med de resultat som uppmätts i projekten.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/904b9d1b-a796-4ce4-ad24-565e5a06b034</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Passive_houses_in_Sweden._From_design_to_evaluation_of_four_demonstration_projects..pdf">https://portal.research.lu.se/files/3262195/1710155.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">14942334</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Energy and Building Design</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Planning process</topic> <topic>Energy efficiency</topic> <topic>Passive house</topic> <topic>Buildingconstruction</topic> <topic>Residential buildings</topic> <topic>Ventilation</topic> </subject> <subject authority="lup"> <topic>Building Technologies</topic> <topic>Civil Engineering</topic> </subject> <relatedItem type="host"> <location> <url>http://www.ebd.lth.se/publikationer</url> </location> </relatedItem> <relatedItem type="host"> <titleInfo> <title>Report No EBD-T--10/12</title> </titleInfo> <identifier type="issn">1651-8136</identifier> <identifier type="isbn">978-91-85147-46-5</identifier> <identifier type="oldLupId">1710148</identifier> <part> <extent unit="pages"> <total>390</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-11-26T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>904b9d1b-a796-4ce4-ad24-565e5a06b034</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:15:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:15:33+02:00</recordDateApproved> </recordInfo> </mods>

The main risk factor for the development of NMSC is UV-irradiation but human papillo-mavirus (HPV) might be a co-factor.&lt;br/&gt;&lt;br&gt; We extended the heterogeneity of the genus Betapapillomavirus by characterizing six putative types, HPV93 (species 1), 96 (species 5), 107, 110, 111 and FA75[KI88-03] (species 2). The prevalence of these types in lesions and paired healthy skin were low (&amp;lt; 7%) and the viral loads spanned from 3 copies/cell to less than 1 copy/35,000 cells. Altogether, the four viruses belonging to Betapapillomavirus species 2 were associated with actinic keratosis. In addition, the E7 protein of HPV92, 93 and 96 was able to bind pRb and induce anchorage-independent growth.&lt;br/&gt;&lt;br&gt; Transcriptional activity from the upstream regulatory regions (URR) of HPV8, 38, 92, 93 and 96 was higher in skin- than mucosaderived cells. Transcriptional start sites were mapped at nucleotide position P92 (HPV38), P45 (HPV92), P7439 (HPV93) and P256 (HPV96). Also, responsiveness to UV-B irradiation showed that HPV8 was activated, HPV38 and 93 down-regulated and HPV 92 and 96 were non-responsive. These variable responses among the HPV types within the genus Betapapillomavirus indicate that it is not likely to predict reactivity to UV-B based on genus. In addition, differentiation was shown to up-regulate the transcriptional activity of HPV8, 93 and 96. &lt;br/&gt;&lt;br&gt; Keratoacanthoma (KA) and SCC are histologically difficult to distinguish and thus 19 biomarkers were immunohistochemically investigated in 25 SCC and 64 KA by tissue microarray. The anti-apoptotic Bcl-xL was detected in 84% of the SCC and in 15% of KA, indicating a possible distinguishing marker. HPV DNA was detected in 22% of SCC and 27% of KA and eighty percent of the HPV isolates belonged to the Betapapillomavirus species 2.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2c405e68-31ae-484e-85aa-9372cb9c0323</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="AVHANDLING_FINAL080413.doc">https://portal.research.lu.se/files/3262668/1150802.doc</url> </location> <physicalDescription> <internetMediaType>application/x-ole-storage</internetMediaType> </physicalDescription> <note type="fileSize">4350464</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>prevalence</topic> <topic>E7 protein</topic> <topic>Non-melanoma skin cancer</topic> <topic>biomarkers</topic> <topic>keratoachantoma</topic> <topic>Human papillomavirus</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Faculty of Medicine Doctoral Dissertation series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-06-4</identifier> <identifier type="oldLupId">1150791</identifier> <part> <detail type="volume"> <number>2008:53</number> </detail> <extent unit="pages"> <total>152</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-20T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>2c405e68-31ae-484e-85aa-9372cb9c0323</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:15:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:15:39+02:00</recordDateApproved> </recordInfo> </mods>

Since the beginning of the century, the use of&lt;br/&gt;&lt;br&gt; coupled in situ zircon U–Pb, Lu–Hf and O isotope analyses&lt;br/&gt;&lt;br&gt; as a tool to address these questions have increased&lt;br/&gt;&lt;br&gt; exponentially. Numerous compilations of ever growing&lt;br/&gt;&lt;br&gt; datasets have been presented, leading to new, and sometimes&lt;br/&gt;&lt;br&gt; contrasting models of continental growth. Many&lt;br/&gt;&lt;br&gt; of theses models, however, suffer from a number of&lt;br/&gt;&lt;br&gt; assumptions, including a mantle reservoir that has been&lt;br/&gt;&lt;br&gt; homogeneously and linearly depleted since the Hadean.&lt;br/&gt;&lt;br&gt; Further, the use of (mainly) detrital zircon, taken out&lt;br/&gt;&lt;br&gt; of their geological context, and the application of their&lt;br/&gt;&lt;br&gt; depleted model-ages clearly hamper the validity of these&lt;br/&gt;&lt;br&gt; models.&lt;br/&gt;&lt;br&gt; To accurately address the question regarding continental&lt;br/&gt;&lt;br&gt; crustal growth using combined zircon U–Pb-Lu–Hf(-O)&lt;br/&gt;&lt;br&gt; isotope data, one needs to have contextual control and&lt;br/&gt;&lt;br&gt; minimise the uncertainties of the applied models.&lt;br/&gt;&lt;br&gt; In papers included in this thesis such an approach has&lt;br/&gt;&lt;br&gt; been used on three different Palaeo- to Meso-Proterozoic&lt;br/&gt;&lt;br&gt; orogenic belts; in Fennoscandia, in North American&lt;br/&gt;&lt;br&gt; Grenville and in the Birimian terrane of the West African&lt;br/&gt;&lt;br&gt; craton.&lt;br/&gt;&lt;br&gt; The eastern part of the Sveconorwegian Province, located&lt;br/&gt;&lt;br&gt; in the southwestern part of the Fennoscandian Shield, is&lt;br/&gt;&lt;br&gt; made up of granitiod rocks that were emplaced through&lt;br/&gt;&lt;br&gt; sequential tapping of a reservoir that formed through&lt;br/&gt;&lt;br&gt; mixing between a 2.1–1.9 Ga juvenile component and&lt;br/&gt;&lt;br&gt; Archaean crust. Between 1.7 and 1.4 Ga the continental&lt;br/&gt;&lt;br&gt; crust of the Eastern Segment was reworked with little or&lt;br/&gt;&lt;br&gt; no generation of new crust.&lt;br/&gt;&lt;br&gt; Further to the west, in the Idefjorden terrane of the&lt;br/&gt;&lt;br&gt; Sveconorwegian Province, 1.65 to 1.33 Ga rocks have&lt;br/&gt;&lt;br&gt; isotopic signatures that indicate reworking of older&lt;br/&gt;&lt;br&gt; continental crust, including sediments. However, overall&lt;br/&gt;&lt;br&gt; the isotopic signatures in the Idefjorden terrane indicate&lt;br/&gt;&lt;br&gt; an increase in juvenile material with time, consistent with&lt;br/&gt;&lt;br&gt; development of an extensional back-arc rift geotectonic&lt;br/&gt;&lt;br&gt; setting, accommodating deposition of the local metasedimentary&lt;br/&gt;&lt;br&gt; basin, Stora Le-Marstrand.&lt;br/&gt;&lt;br&gt; Isotope data from rocks within the Grenville orogen in&lt;br/&gt;&lt;br&gt; subsurface Ohio suggest a common c. 1.65 Ga juvenile&lt;br/&gt;&lt;br&gt; source to a majority of the sampled bedrock. Emplacement&lt;br/&gt;&lt;br&gt; of this juvenile crustal contribution was followed&lt;br/&gt;&lt;br&gt; by sequential reworking of that reservoir with little or no&lt;br/&gt;&lt;br&gt; additional contribution to the source.&lt;br/&gt;&lt;br&gt; The c. 2.31–2.06 Ga Birimian terrane in Ghana, West&lt;br/&gt;&lt;br&gt; African craton, is a commonly cited example of plume&lt;br/&gt;&lt;br&gt; initiated crustal growth, that is known to have largely&lt;br/&gt;&lt;br&gt; juvenile signatures. However, we can show that reworked&lt;br/&gt;&lt;br&gt; Archaean crust contribute in a much larger extent than&lt;br/&gt;&lt;br&gt; previously known, once again highlighting the importance&lt;br/&gt;&lt;br&gt; of infracrustal reworking during emplacement of&lt;br/&gt;&lt;br&gt; continental crust. Further, the emplacement of felsic&lt;br/&gt;&lt;br&gt; rocks during the Eoeburnean pre-dates suggested plume&lt;br/&gt;&lt;br&gt; related rocks, contradicting a suggested plume initiated&lt;br/&gt;&lt;br&gt; crustal growth.&lt;br/&gt;&lt;br&gt; Collectively, these studies highlight the importance of&lt;br/&gt;&lt;br&gt; infracrustal reworking in Palaeo- to Meso-Proterozoic&lt;br/&gt;&lt;br&gt; accretionary orogens. These studies also provide good&lt;br/&gt;&lt;br&gt; examples of combined zircon U–Pb-Lu–Hf-(O) isotope&lt;br/&gt;&lt;br&gt; analyses on rocks and rock suites with known affinity&lt;br/&gt;&lt;br&gt; where the validity of chosen models can be justified.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; För att förstå tillväxten av den kontinentala jordskorpan&lt;br/&gt;&lt;br&gt; är det nödvändigt att kunna uppskatta balansen mellan&lt;br/&gt;&lt;br&gt; juvenilt bidrag från manteln, infra-krustal omarbetning&lt;br/&gt;&lt;br&gt; av jordskorpa och transport av krustalt material tillbaka&lt;br/&gt;&lt;br&gt; till manteln. Sedan början av seklet har användandet&lt;br/&gt;&lt;br&gt; av in situ U–Pb, Lu–Hf och O-isotop analyser av&lt;br/&gt;&lt;br&gt; mineralet zirkon som ett verktyg för att adressera dessa&lt;br/&gt;&lt;br&gt; frågor ökat exponentiellt. Många sammanställningar av&lt;br/&gt;&lt;br&gt; ständigt växande databaser, som använder kombinerade&lt;br/&gt;&lt;br&gt; U–Pb-Lu–Hf och/eller U–Pb-Lu–Hf-O isotop-data,&lt;br/&gt;&lt;br&gt; har presenterats tillsammans med modeller som påvisar&lt;br/&gt;&lt;br&gt; globala konsekvenser för den kontinentala jordskorpans&lt;br/&gt;&lt;br&gt; tillväxt. Många av dessa modeller, lider dock av&lt;br/&gt;&lt;br&gt; ett antal antaganden, bland annat inkluderandet av en&lt;br/&gt;&lt;br&gt; homogen mantelreservoar som utarmats linjärt sedan&lt;br/&gt;&lt;br&gt; jordens skapelse.&lt;br/&gt;&lt;br&gt; Användandet av framför allt detritala zirkoner tagna ur&lt;br/&gt;&lt;br&gt; sitt geologiska sammanhang, och tillämpningen av dess&lt;br/&gt;&lt;br&gt; modell-åldrar, försvagar trovärdigheten hos dessa modeller.&lt;br/&gt;&lt;br&gt; För att ta itu med frågan om den kontinentala&lt;br/&gt;&lt;br&gt; jordskorpans tillväxt, med hjälp av kombinerad zirkon&lt;br/&gt;&lt;br&gt; U–Pb-Lu–Hf (-O) isotop-data, måste man ha kontextuell&lt;br/&gt;&lt;br&gt; kontroll och minimera osäkerheterna i de tillämpade&lt;br/&gt;&lt;br&gt; modellerna.&lt;br/&gt;&lt;br&gt; I denna avhandling har ett sådant tillvägagångssätt använts&lt;br/&gt;&lt;br&gt; på tre olika Palaeo- och Meso-Proterozoiska (2500–1000&lt;br/&gt;&lt;br&gt; miljoner år gamla) orogena bälten; i den Fennoskandiska&lt;br/&gt;&lt;br&gt; skölden, i nordamerikanska Grenville provinsen och i den&lt;br/&gt;&lt;br&gt; Birimiska terrängen på den västafrikanska kratonen.&lt;br/&gt;&lt;br&gt; Den östra delen av den Svekonorvegiska provinsen (belägen&lt;br/&gt;&lt;br&gt; i de sydvästra delarna av den Fennoskandiska skölden)&lt;br/&gt;&lt;br&gt; skapades genom sekventiell omarbetning av en reservoar&lt;br/&gt;&lt;br&gt; som bildades genom blandning mellan en 2.1–1.9&lt;br/&gt;&lt;br&gt; miljarder år gammal juvenil komponent samt Arkeisk&lt;br/&gt;&lt;br&gt; skorpa. Från 1.7 till och med 1.4 miljarder år sedan&lt;br/&gt;&lt;br&gt; genererades den kontinentala jordskorpan med liten eller&lt;br/&gt;&lt;br&gt; ingen tillförsel av juvenilt material.&lt;br/&gt;&lt;br&gt; Längre västerut, i Idefjordsterrängen av Svekonorvegiska&lt;br/&gt;&lt;br&gt; provinsen, återfinns 1.65–1.33 miljarder år gammal&lt;br/&gt;&lt;br&gt; berggrund med isotopsignaturer som indikerar omarbetning&lt;br/&gt;&lt;br&gt; av äldre kontinental jordskorpa och sediment.&lt;br/&gt;&lt;br&gt; På det hela taget indikerar dock isotopsignaturerna från&lt;br/&gt;&lt;br&gt; berggrunden i Idefjordsterrängen en ökning av juvenilt&lt;br/&gt;&lt;br&gt; material med tiden. Detta är i linje med en retirerande&lt;br/&gt;&lt;br&gt; öbåge, samtida med avsättning av den lokala sedimentära&lt;br/&gt;&lt;br&gt; bassängen, Stora Le-Marstrand.&lt;br/&gt;&lt;br&gt; Trender i isotopdata från den Grenvilliska orogenen&lt;br/&gt;&lt;br&gt; under Ohio föreslår juvenilt bidrag från manteln för ca.&lt;br/&gt;&lt;br&gt; 1.65 miljarder år sedan, följt av sekventiell omarbetning&lt;br/&gt;&lt;br&gt; av denna reservoar med litet eller inget ytterligare bidrag&lt;br/&gt;&lt;br&gt; från manteln.&lt;br/&gt;&lt;br&gt; Den ca. 2.31–2.06 miljarder år gamla Birimiska terrängen&lt;br/&gt;&lt;br&gt; i Ghana, är känd för att till hög grad uppvisa juvenila&lt;br/&gt;&lt;br&gt; signaturer. Men vi kan visa att omarbetad Arkeisk skorpa&lt;br/&gt;&lt;br&gt; bidragit i mycket större utsträckning än tidigare känt,&lt;br/&gt;&lt;br&gt; vilket återigen betonar vikten av infrakrustal omarbetning&lt;br/&gt;&lt;br&gt; under bildandet av kontinental jordskorpa. Vi kan&lt;br/&gt;&lt;br&gt; även påvisa att denna terräng, som normalt beskrivs som&lt;br/&gt;&lt;br&gt; bildad via initialt bidrag från en mantelplym, har granitiska&lt;br/&gt;&lt;br&gt; bergarter som är äldre än de mafiska leden. Detta&lt;br/&gt;&lt;br&gt; påvisar istället en subduktionsrelaterad tillväxt för den&lt;br/&gt;&lt;br&gt; kontinentala krustan i denna terräng.&lt;br/&gt;&lt;br&gt; Tillsammans understryker dessa studier vikten av infrakrustal&lt;br/&gt;&lt;br&gt; omarbetning i Palaeo- och Meso-Proterozoiska&lt;br/&gt;&lt;br&gt; ackretionsorogener. Dessa studier ger också goda exempel&lt;br/&gt;&lt;br&gt; på tillämpning av kombinerade zirkon U–Pb-Lu–Hf&lt;br/&gt;&lt;br&gt; (-O) isotop- analyser av berggrund med känd affinitet,&lt;br/&gt;&lt;br&gt; där valet av använda modeller kan styrkas.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/bb33da18-045c-4ea2-9f3e-816e3742b681</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappan_Andreas_Petersson.pdf">https://portal.research.lu.se/files/3262815/7854093.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2465925</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Geology, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>crustal reworking</topic> <topic>Proterozoic</topic> <topic>O-isotopes</topic> <topic>Lu–Hf</topic> <topic>U–Pb</topic> <topic>zircon</topic> <topic>Crustal growth</topic> </subject> <subject authority="lup"> <topic>Geology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Litholund theses</title> </titleInfo> <identifier type="issn">1651-6648</identifier> <identifier type="issn">1651-6648</identifier> <identifier type="isbn">978-91-87847-05-9</identifier> <identifier type="isbn">978-91-87847-06-6</identifier> <identifier type="oldLupId">7853963</identifier> <part> <detail type="issue"> <number>24</number> </detail> <extent unit="pages"> <total>171</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-10-02T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>bb33da18-045c-4ea2-9f3e-816e3742b681</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:15:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:15:41+02:00</recordDateApproved> </recordInfo> </mods>

Despite evidence of better&lt;br/&gt;&lt;br&gt; perioperative outcome compared to laparotomy, laparoscopy is mostly performed for less advanced surgical&lt;br/&gt;&lt;br&gt; procedures and the uptake of laparoscopic hysterectomy has been slow. An effort to preserve the clinical benefits&lt;br/&gt;&lt;br&gt; of laparoscopic surgery and facilitate the performance of more advanced surgery has led to the development of&lt;br/&gt;&lt;br&gt; robot-assisted laparoscopic surgery. Technical progress has been advantageous for the patient from a historical&lt;br/&gt;&lt;br&gt; point of view, but this cannot be assumed without proper evaluation. As for all surgical approaches, it is important&lt;br/&gt;&lt;br&gt; to recognize the possible applications of robotic surgery as well as proper patient selection both from a clinical and&lt;br/&gt;&lt;br&gt; economical point of view. The overall aim of this thesis was to investigate the possible applications, clinical&lt;br/&gt;&lt;br&gt; outcome and hospital cost of robot-assisted laparoscopic surgery for benign uterine disease at a single institution&lt;br/&gt;&lt;br&gt; following the introduction of robotic surgery.&lt;br/&gt;&lt;br&gt; Study I: Evaluating the first 1000 robotic surgeries performed showed that a surgical robot provides the possibility&lt;br/&gt;&lt;br&gt; to offer minimally invasive surgery to a larger patient population with low rates of conversions and intraoperative&lt;br/&gt;&lt;br&gt; complications. Study II: 31 women with symptomatic, deep intramural myomas and either otherwise unexplained&lt;br/&gt;&lt;br&gt; infertility or myomas with a possible effect on conception had a pregnancy rate following robotic myomectomy of&lt;br/&gt;&lt;br&gt; 68%. Study III: All women (n=114) with a BMI ≥ 30 kg/m2 who underwent a simple hysterectomy by robotics or&lt;br/&gt;&lt;br&gt; laparotomy during the study period were included. Robot-assisted laparoscopic hysterectomy in obese women was&lt;br/&gt;&lt;br&gt; associated with shorter hospital stay, less bleeding, and fewer complications and longer operative time compared&lt;br/&gt;&lt;br&gt; to laparotomy although the operative times for morbidly obese women were similar between robotics and&lt;br/&gt;&lt;br&gt; laparotomy. Study IV: 122 women planned for minimally invasive hysterectomy for benign disease were&lt;br/&gt;&lt;br&gt; randomly allocated to either robot-assisted- or traditional, minimally invasive hysterectomy in a 1:1 proportion&lt;br/&gt;&lt;br&gt; with vaginal hysterectomy as a primary choice in the latter. From the perspective of hospital costs, robotic-assisted&lt;br/&gt;&lt;br&gt; hysterectomy is not advantageous for treating non-complex benign conditions when a vaginal approach is feasible&lt;br/&gt;&lt;br&gt; in a high proportion of patients. A similar hospital cost is attainable for laparoscopy and robotics when the robot is&lt;br/&gt;&lt;br&gt; a preexisting investment. Study V: Complication rates in 949 women planned for robotic hysterectomy for&lt;br/&gt;&lt;br&gt; malignant (75%) and benign (25%) gynecological disease over an 8-year period with special awareness of&lt;br/&gt;&lt;br&gt; complications possibly related to robot specific risk factors. Intraoperative- and postoperative complications and&lt;br/&gt;&lt;br&gt; complications possibly related to the robotic approach diminish with training, experience and refinement of&lt;br/&gt;&lt;br&gt; practice. Study VI: All women (n=483) undergoing hysterectomy for benign disease during 2013 and 2014.&lt;br/&gt;&lt;br&gt; Vaginal hysterectomy was associated with the lowest hospital cost and robotic hysterectomy with the lowest rate of perioperative complications. Procedure-specific proficiency influences outcome. Robotic hysterectomy for&lt;br/&gt;&lt;br&gt; benign disease is clinically advantageous and economically feasible in complex cases, when performed by high&lt;br/&gt;&lt;br&gt; volume surgeons.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/368a7b68-e04e-49b6-a47b-79e49ed812f4</url> </location> </relatedItem> <originInfo> <publisher>Department of Obstetrics and Gynecology, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>hysterectomy</topic> <topic>myomectomy</topic> <topic>robotic surgery</topic> <topic>complications</topic> <topic>outcome</topic> <topic>hospital cost</topic> </subject> <subject authority="lup"> <topic>Gynaecology, Obstetrics and Reproductive Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-219-1</identifier> <identifier type="oldLupId">8170931</identifier> <part> <detail type="volume"> <number>139</number> </detail> <extent unit="pages"> <total>72</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/?term=The+effect+of+increased+experience+on+complications+in+robotic+hysterectomy+for+malignant+and+benign+gynecological+disease.</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/pubmed/?term=Implementation+and+applications+of+robotic+surgery+within+gynecologic+oncology+and+gynecology%3B+analysis+of+the+first+thousand+cases.</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-12-11T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>368a7b68-e04e-49b6-a47b-79e49ed812f4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:15:46+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:15:46+02:00</recordDateApproved> </recordInfo> </mods>

In a healthy human, the HSC produces 1,000,000,000,000 cells per day, illustrating the high turnover within the hematopoietic system and the need for replenishments by HSCs. The mechanisms behind self-renewal are largely unresolved, and we have therefore investigated the potential role of the cytokine receptors Kit and c-Mpl and their respective ligands, Kit ligand and Thrombopoietin (Thpo), in regulation of HSC self-renewal. &lt;br/&gt;&lt;br&gt; Using mice that have partial (KitW41/W41) and complete (Thpo-/-) loss of function mutations of the Kit receptor and Thpo ligand respectively, we have demonstrated a reduction of bone marrow HSCs during steady-state conditions, a reduction that is further exacerbated with age, suggesting important roles of Kit and Thpo in steady-state maintenance of hematopoiesis. In addition, decreased regeneration of the HSC compartment of myeloablated mice post transplantation argues for an important role of these two cytokines in regulating HSCs during conditions of stress. We can further provide evidence that link this inability to increased cell cycle turnover within the HSC compartment in the absence of Kit and Thpo. Further, we provide evidence for Kit being important in Thpo independent residual hematopoiesis.&lt;br/&gt;&lt;br&gt; Taken together, our findings suggest that Kit and c-Mpl and their respective ligands, Kit ligand and Thpo regulate HSC maintenance, and might exert this function by playing a role in keeping the bone marrow HSCs quiescent.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/30d1b5d5-889f-4559-adb0-06225680d943</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="sammansatt_for_web.pdf">https://portal.research.lu.se/files/3267636/1049315.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3362148</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund Strategic Research Center for Stem Cell Biology and Cell Therapy, Faculty of Medicine, Lund University.</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>thrombopoietin</topic> <topic>hematopoiesis</topic> <topic>Thpo</topic> <topic>c-kit</topic> <topic>stem cells</topic> </subject> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-96-4</identifier> <identifier type="oldLupId">1049309</identifier> <part> <detail type="volume"> <number>2008:43</number> </detail> <extent unit="pages"> <total>58</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-04-08T09:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The blood-brain barrier (BBB) protects the mammalian brain from potentially harmful substances circulating in the blood. The permeability of the BBB has been shown to be increased after exposure to electromagnetic fields (EMFs) of the kind emitted by mobile phones and neuronal damage has been found several weeks after the exposure. &lt;br/&gt;&lt;br&gt; The aim of this thesis was to further investigate the effects of exposure to global system for mobile communications (GSM) radiation upon the rat brain. &lt;br/&gt;&lt;br&gt; In Paper I, rats were exposed to GSM radiation for two hours, followed by a seven-day recovery period after which the animals were sacrificed. The GSM exposed rats had a significantly increased BBB permeability as compared to the sham exposed control rats, seen as increased amount of albumin extravasation. &lt;br/&gt;&lt;br&gt; In Paper II, we examined the effects of long-term exposure of rats for totally 55 weeks, 2 hours weekly, to GSM radiation. After this protracted exposure, an open-field test demonstrated no behavioural changes. On the other hand, the episodic memory was impaired after GSM exposure, as demonstrated in the episodic-like memory test. In Paper III histopathological light microscopial examinations of the long-term GSM exposed animals were presented. Albumin extravasation, neuronal damage and signs of accelerated ageing were investigated. No significant difference between the GSM exposed and sham control rats was seen. &lt;br/&gt;&lt;br&gt; In Paper IV, microarray analysis of the gene expression in cortex and hippocampus of mobile phone exposed rats was performed. 31, 099 rat genes, including splicing variants, were analyzed. At the single gene level, no statistically significant alterations could be seen. However, with Gene Ontology (GO) analysis, 25 predefined GO categories had significantly altered gene expression in cortex and 20 GO categories had significantly altered gene expression in hippocampus. Four GO categories were among the ten most significantly altered groups in both cortex and hippocampus after GSM exposure; that is, extracellular region, signal transducer activity, intrinsic to membrane and integral to membrane. &lt;br/&gt;&lt;br&gt; Considering the vast number of mobile phone users today, the non-thermal effects of mobile phoning and the mechanisms behind them, must indeed continue to be investigated.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1be8b651-24b6-4524-84e9-099505036503</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>mobile phone</topic> <topic>electromagnetic radiation</topic> <topic>Blood-brain barrier</topic> <topic>brain</topic> <topic>rat</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-64-4</identifier> <identifier type="oldLupId">1267250</identifier> <part> <detail type="volume"> <number>2008:111</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-06T09:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Hip fracture predominantly affects an already frail population and is associated with multi-cause morbidity and high mortality. Improved knowledge of long-term outcome is essential in order to improve future care and prevention of both fracture and its complications.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis, all hip fracture patients during 1984-1985 in Malmö, Sweden (766 women, 263 men) were followed within a remaining lifetime perspective to a maximum of 26 years and compared with a background population matched for age and sex.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Hip fracture patients had a higher mortality, in comparison to the control population. The size of the differences was highly dependent on age at the time of the hip fracture and whether it was a woman or a man. Excess mortality was highest during the first year following the hip fracture but remained increased for 20 years. The most common cause of death was cardiovascular disease, with a 50% relative risk increase in hip fracture patients. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Despite the shorter survival and the subsequent shorter time at risk of new fractures, almost half of all female and almost one third of all male patients suffered at least one new fracture after the hip fracture. Women more often fractured on multiple occasions. The 10-year mortality-adjusted risk of new fractures was 40% for women, whereas a comparatively similar 36% risk was reached after 5 years in men. The mortality-adjusted remaining lifetime risk of new fracture was 85% for women and 62% for men. By analyzing women and men separately and by age-groups, the youngest patients, those below age 75 years, were at highest risk of new fractures, whereas patients above 85 years had a risk that was no different to that of the controls. The most common new fractures in both patients and controls were those of the hip and vertebrae, while the risk size was dependent on sex and age. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; These findings highlight the importance of stratifying for age and sex when analyzing outcomes both in the short and long term in hip fracture patients.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Osteoporos (benskörhet) innebär att såväl bentätheten som skelettets hållfasthet minskar, vilket leder till ökad risk att få frakturer (benbrott). Osteoporos är en folksjukdom, där frakturerna medför stora kostnader såväl för individen som för samhället. De frakturer som räknas som osteoporosfrakturer är i första hand de som drabbar höft, bäcken, axel, handled och kota. De som redan haft en osteoporosfraktur har en dubbelt så hög risk att få flera frakturer även vid lindrigt våld. Av frakturerna är höftfrakturen den som ger störst konsekvenser för den drabbade. Tre av fyra höftfraktur-patienter är kvinnor där majoriteten är gamla, ofta med andra komplicerande sjukdomar. Trots att det idag finns behandling mot osteoporos som effektivt kan minska risken för fraktur, är det få frakturpatienter som får förskrivet dessa mediciner. Detta innebär att osteoporos är både under-diagnostiserat och underbehandlat. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Syftet med studierna i denna avhandling är att identifiera skillnader i överlevnad på kort och lång sikt efter en höftfraktur och kvantifiera risken för nya frakturer i förhållande till ålder och kön. I studien ingår alla patienter, 766 kvinnor och 263 män, som drabbades av en höftfraktur i Malmö 1984/85 p.g.a. en lågenergiskada, d.v.s. att de snubblat eller fallit på golvet eller motsvarande. Dessa patienter jämförs med kontrollpersoner ur normal-befolkningen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingens första del beskrivs de kvinnliga höftfrakturpatienterna, som följdes i 22 år. Medelåldern var 80 år när de drabbades av höftfrakturen och nästan alla följdes livet ut. Endast 1 av 20 var kvar i livet vid upp-följningens slut. Redan inom ett år hade 1 av 5 dött, hälften var döda inom fem år och efter tio år fanns bara 1 av 4 kvar i livet. Knappt hälften av kvinnorna drabbades av nya frakturer under sin återstående livstid, i genomsnitt två nya frakturer. Risken att drabbas av nya frakturer var störst hos de yngre kvinnorna. För varje år en kvinna överlevde efter höftfrakturen ökade risken och vid uppföljningens slut hade nästan alla (85%) drabbats av minst en ny fraktur.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingens andra del beskrivs de manliga höftfrakturpatienterna. Dessa var yngre när de drabbades av sin höftfraktur, medelålder 76 år, och hade en högre tidig dödlighet. Av män med höftfraktur dog var tredje inom ett år och 6 av 10 inom fem år. Efter tio år var bara var femte man kvar i livet. Dödligheten var mest påtaglig hos männen över 85 år, där hälften dog redan inom 3 månader. Knappt en tredjedel drabbades av nya frakturer. Flest nya frakturer fick de män som var mellan 75-84 år där 4 av 10 drabbades, medan den långsiktiga risken var störst hos de yngre männen – precis som hos kvinnorna, eftersom dessa överlevde längre.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I nästa arbete tas reda på i hur stor utsträckning höftfrakturpatienterna skiljer sig från normalbefolkningen, när det gäller dödlighet och dödsorsak, i en jämförelse mellan alla höftfrakturpatienter och ålders- och könsmatchade kontrollpersoner. En högre dödlighet sågs under hela studieperioden hos både manliga och kvinnliga höftfrakturpatienter jämfört med kontroller, likaså inom varje åldersgrupp (under 75 år, 75-84 år, över 85 år). Relativt sett var dödligheten högst hos de yngre männen, de under 75 år. Den vanligaste dödsorsaken var hjärt-kärlsjukdom. Om man tog hänsyn till när dödsfallen inträffade, så hade både manliga och kvinnliga höft-frakturpatienter cirka 50% ökad risk att dö i hjärt-kärlsjukdomar jämfört &lt;br/&gt;&lt;br&gt; med kontrollpersonerna.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I sista arbetet analyseras om höftfrakturpatienter har större risk att få nya frakturer jämfört med kontrollpersonerna. Nya frakturer inträffar hos närmare hälften av alla kvinnor, både höftfrakturpatienter och kontrollpersoner, och hos en tredjedel av de manliga höftfraktur-patienterna jämfört med var fjärde av de manliga kontrollpersonerna. Både kvinnliga och manliga höftfraktur-patienter hade en ökad risk över tid att drabbas av nya frakturer jämfört med kontrollpopulationen, förutom hos de allra äldsta (över 85 år). De höftfrakturpatienter som var relativt sett yngre när de drabbades av höftfrakturen, hade högre risk att drabbas av nya frakturer. De vanligaste nya frakturerna var höft-fraktur och kotfraktur hos både patienter och kontroller.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis så har höft-frakturpatienter en ökad dödlighet och en ökad frakturrisk i förhållande till jämförbara personer i normal-befolkningen. Dessa studier visar att det är stora skillnader mellan kvinnor och män över tid, skillnader som dessutom är starkt åldersberoende. Denna kunskap har betydelse, inte minst för hur man lägger upp framtida åtgärder för att förebygga nya frakturer hos höftfraktur-patienter.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0f773871-a17b-433a-91d7-79bd8a8efca8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_G5.pdf">https://portal.research.lu.se/files/3267972/1590135.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1667937</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Clinical and Molecular Osteoporosis Research Unit, Clinical Sciences, Malmö.</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>hip fracture</topic> <topic>women</topic> <topic>men</topic> <topic>sex</topic> <topic>age</topic> <topic>survival</topic> <topic>mortality</topic> <topic>subsequent fracture</topic> <topic>fracture risk</topic> <topic>residual lifetime</topic> <topic>cause of death</topic> <topic>long term</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-69-6</identifier> <identifier type="oldLupId">1590131</identifier> <part> <detail type="volume"> <number>2010:54</number> </detail> <extent unit="pages"> <total>144</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-12T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>0f773871-a17b-433a-91d7-79bd8a8efca8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:02+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:02+02:00</recordDateApproved> </recordInfo> </mods>

Hormone-sensitive lipase (HSL) is a key enzyme in the mobilization of fatty acids from acylglycerols in adipocytes, but also plays important roles in other cell types.&lt;br/&gt;&lt;br&gt; The aim of this thesis has been to study the consequences of a targeted disruption of the HSL gene in mice, with a focus on the white adipose tissue (WAT). &lt;br/&gt;&lt;br&gt; The initial study demonstrated a mild insulin resistance in multiple tissues of the HSL null mice, which was almost fully compensated for by increased insulin secretion by the pancreatic beta-cells. &lt;br/&gt;&lt;br&gt; The HSL null mice were resistant to high-fat diet (HFD)-induced obesity, with severely reduced WAT. A proteomic analysis suggested a local inflammatory response in WAT of HSL null mice, supported by the findings of increased macrophage infiltration in this tissue. Increased energy expenditure and perturbed adipogenesis are possible explanations to the lean phenotype of HSL null mice. Acquirement of brown adipocyte features in white adipocytes was shown in HFD-fed HSL null mice demonstrated by increased UCP-1 expression and oxygen consumption in these cells. A high retinyl ester hydrolase activity of HSL was demonstrated which was almost absent in HSL null mice, suggested that retinoic acid could be a potential ligand normally supplied by HSL. Administration of retinoic acid to the diet partly restored the WAT mass and normalized the levels of several cofactors involved in the differentiation towards the white adipocyte lineage. &lt;br/&gt;&lt;br&gt; The collected data suggests a working model where HSL is responsible for the generation of a retinoid ligand that is crucial for adipocyte determination and differentiation and/or survival of mature adipocytes. Failure to supply this ligand, seen in the HSL null model, results in impaired adipogenesis, attainment of brown adipocyte characteristics in classical WAT depots and a local inflammation in WAT. Increased infiltration of macrophages triggers the release of proinflammatory mediators from WAT e.g. tumor necrosis factor alpha, causing systemic inflammation precipitating in insulin resistance. &lt;br/&gt;&lt;br&gt; Thus, in addition to its key role in energy homeostasis, HSL appears to play an important role by providing signals for transcriptional regulation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8329f6bf-4b85-4c25-9a9c-4bdde43aac97</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappan_Kristoffer_Strom__84.pdf">https://portal.research.lu.se/files/3268244/1146582.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1058800</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>retinoid</topic> <topic>adipogenesis</topic> <topic>adipocyte determination</topic> <topic>HSL</topic> <topic>WAT</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> <topic>Medical and Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-08-8</identifier> <identifier type="oldLupId">1146070</identifier> <part> <detail type="volume"> <number>2008:55</number> </detail> <extent unit="pages"> <total>164</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-23T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>8329f6bf-4b85-4c25-9a9c-4bdde43aac97</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:05+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:05+02:00</recordDateApproved> </recordInfo> </mods>

These rare stem cells can both self-renew to maintain the HSC pool, and differentiate to continuously replenish lost blood cells. The mechanisms of HSC regulation are not fully known. The aim of this thesis was to study the role of the Hippo signaling pathway in HSCs. The Hippo pathway is a newly discovered signaling pathway, which regulates organ size in Drosophila. Hippo signaling has further been implicated in regulation of mammalian stem cells. In Article I we developed a new way of modeling genetic changes by combining genetic engineering of murine ES cells with blastocyst complementation. This approach avoids the cost and time constraints associated with the creation of standard transgenic mouse strains while taking advantage of the sophisticated site-directed manipulations that are possible in ES cells. In Article II we studied YAP1, the downstream effector in the Hippo pathway. We created a transgenic model with inducible YAP1 expression exclusively within the hematopoietic system using the blastocyst complementation approach developed in article I. When investigating the effect of overexpressing YAP1 in HSCs we detected no effect on HSC function during steady state or regenerative stress. This is contrast to effects seen in other tissue stem cells and suggests tissue specific functions of YAP1 in regulation of stem cells. In Article III we investigated a knockout model for the other Hippo effector Taz. Adult mice deficient in Taz display no changes in hematopoietic parameters but are born below mendelian ratios. Taz thus seems dispensable for adult hematopoiesis but may influence embryonic development. &lt;br/&gt;&lt;br&gt; Taken together, using both novel and traditional genetic engineering approaches in mice, we have taken the first steps to understand the role of the Hippo pathway in hematopoiesis.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; I vår kropp genereras konstant ett stort antal nya blodceller för att ersätta de som går förlorade. Olika sorters blodceller är ansvariga för att transportera syre till alla våra vävnader, hjälpa till med blodets koagulering vid skador och att slåss mot infektioner orsakade av bakterier och virus. All blodceller härstammar från en liten population med blodstamceller som finns i benmärgen. Dessa stamceller har kapaciteten att både dela sig och bilda nya dotterceller som även de är stamceller, samt att dela sig och bilda dotterceller som mognar till de specialiserade blodcellerna. Man vet idag inte riktigt hur blodstamcellerna instrueras att välja mellan att bli dessa två typer av dotterceller och inte heller vad för faktorer som gör att de är stamceller. I mitt projekt har jag tittat på en signalerings väg, kallad Hippo, som finns i celler och som ännu inte har undersökts i blodceller. För att göra det så började jag med att komma på ett system för hur man kan titta på vad som händer i blodstamceller när uttrycket av en gen ökar. I våra laboratorier använder vi mest möss för att göra våra studier eftersom de liknar oss människor ganska mycket. Så mitt system går ut på att skapa ett uttryck av en gen som kan slås av och på bara i blodceller genom att ge möss en antibiotika i deras dricksvatten. Efter att ha kontrollerat så att systemet fungerade så använde jag det för att titta på vad som händer med blodstamceller om en gen i min signalerings väg, YAP, har mycket högre uttryck än normalt. Jag testade funktionen hos stamcellerna genom att transplantera dem till möss som fått hela sitt blodsystem utslaget med strålning och kunde därmed visa att YAP-cellerna varken hade bättre eller sämre förmåga att ersätta det gamla blodsystemet. Eftersom det finns två gener i Hippo signaleringsvägen som kan täcka upp för varandra, YAP och Taz, så studerade jag sen också vad som händer om man tar bort allt genuttryck från Taz i blod celler. Att ta bort Taz i vuxna möss påverkar inte deras blodceller utan dessa förblir normala vilket indikerar att Taz inte behövs för blodbildning i vuxna. Sammantaget är detta de första studier som gjorts på Hippo signalering i blodsystemet och även om varken överuttryck av YAP eller borttagande av Taz verkar ha någon inverkan så måste man göra många fler studier för att se om Hippo signaleringsvägen reglerar stamcells processer i blodet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3abc9342-4173-4c06-8fd3-c4f528dd8727</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis_Times-Arial_G5_v12_spikning.pdf">https://portal.research.lu.se/files/3269912/2370126.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2849913</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>stem cells</topic> <topic>hematopoiesis</topic> <topic>Hippo pathway</topic> <topic>hematopoietic stem cells</topic> </subject> <subject authority="lup"> <topic>Hematology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-8687-85-7</identifier> <identifier type="oldLupId">2370099</identifier> <part> <detail type="volume"> <number>2012:23</number> </detail> <extent unit="pages"> <total>88</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-03-30T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>3abc9342-4173-4c06-8fd3-c4f528dd8727</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:25+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:04:02Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:25+02:00</recordDateApproved> </recordInfo> </mods>

The goal is to provide improved decision support to physicians regarding the optimal selection of patients for two costly, invasive therapies – percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (MI) and implantable cardioverter defibrillators (ICDs) for patients with heart failure and reduced left ventricular ejection fraction (LVEF). The ECG methods evaluated in this thesis are compared to the gold standard imaging techniques of myocardial perfusion single photon emission computed tomography (SPECT) for ischemia and contrast-enhanced magnetic resonance imaging (MRI) for myocardial scar. Additionally, ECG methods to identify and quantify myocardial scar are evaluated as a novel tool to identify vulnerability to ventricular arrhythmias. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Myocardial infarction from acute coronary occlusion is a leading cause of morbidity and mortality. Reperfusion therapy with thrombolytics or PCI reduces mortality; however, the therapies come with significant risk and must be given within a narrow time frame. Knowledge of the location, size and acuteness of ischemic myocardium at risk for infarction could help predict the potential for myocardial salvage and impact patient triage and choice of reperfusion therapy. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Following infarction, non-salvaged myocardium undergoes remodeling, resulting in chronic scar. In addition, myocardial scars can develop in nonischemic cardiomyopathies. While recent clinical trials have shown that ICDs reduce mortality in patients with low LVEF, the annual rate of appropriate ICD shocks is only 5%. Since myocardial scar forms the substrate required for precipitating and propagating reentrant ventricular tachyarrhythmias, detecting and quantifying scar in patients may result in improved risk stratification. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studies I and II assessed ECG algorithms to quantify the location, size and acuteness of myocardial ischemia. Study I demonstrated that the three-dimensional ST-segment vector derived from the ECG can be graphically projected onto a model of the left ventricle to determine ischemia location and ST-vector magnitude correlates with ischemia size measured by myocardial perfusion SPECT. Study II demonstrated that the Anderson-Wilkins ECG-acuteness score is superior to time-from-symptom onset to PCI for predicting myocardial salvage assessed by myocardial perfusion SPECT and contrast-enhanced MRI. In addition, computer simulation showed that the ECG sign of salvageable myocardium, tall T-waves, could only be produced by shortened action potential duration, which has previously been associated with preconditioning.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studies III and IV evaluated novel Selvester QRS scoring systems for use in the presence or absence of ECG confounders to quantify myocardial scar and predict ventricular arrhythmias. Study III demonstrated that QRS scoring accurately identifies and quantifies scar when validated against contrast-enhanced MRI. Furthermore, higher QRS-score scar size is associated with ventricular arrhythmia susceptibility, as defined by increased frequency of monomorphic ventricular tachycardia induction during electrophysiologic programmed stimulation. Study IV extended the application of QRS scoring to 797 patients with heart failure and reduced LVEF who received ICDs for the primary prevention of sudden arrhythmic death. Increasing QRS score was independently associated with increased ICD shocks and patients with a QRS score of zero (no scar) had a significantly reduced risk of ICD shocks. The predictive value of QRS-score scar size was complementary to that of LVEF and other clinical characteristics.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2cdbdfa6-59fa-4045-936a-cf609f3c08e4</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Physiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Electrocardiography</topic> <topic>Imaging</topic> <topic>Arrhythmias</topic> <topic>Ischemia</topic> <topic>Infarction</topic> <topic>Cardiomyopathy</topic> <topic>SPECT</topic> <topic>MRI</topic> </subject> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-17-7</identifier> <identifier type="oldLupId">1529083</identifier> <part> <detail type="volume"> <number>2010:3</number> </detail> <extent unit="pages"> <total>92</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-01-15T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>2cdbdfa6-59fa-4045-936a-cf609f3c08e4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:26+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:26+02:00</recordDateApproved> </recordInfo> </mods>

Impaired insulin secretion plays a major role in the pathophysiology of T2D, it is mainly attributed to beta cell function i.e. failure to secrete insulin or reduced beta cell mass. The exocytotic process is crucial for beta cell function and its dysregulation leads to impaired insulin secretion. Therefore, understanding the central mechanisms involved in the regulation of exocytosis is essential to recognize possible targets for therapeutic intervention and treatment of T2D. In this thesis I have investigated the role of Ca2+, miRNAs and rosuvastatin in the regulation of ion channels, exocytosis and insulin secretion of beta cells. For this purpose, pancreatic rat INS-1 832/13 beta cells, rodent animal models, and islets from human cadaver donors has been used. Whole-cell patch clamp was used to study exocytosis measured as changes in cell membrane capacitance. &lt;br/&gt;&lt;br&gt; In beta cells, biphasic exocytotic pattern was previously mainly attributed to insulin granule pool depletion. In paper I, we used the pulse length protocol and mixed-effect modelling; the latter takes care of cellular heterogeneity, to study exocytosis as a function of Ca2+ influx (measured as Q). The data suggests that pool depletion plays a minor role in observed biphasic exocytotic pattern in INS-1 832/13 cells; instead exocytosis is mostly determined by the kinetics of Ca2+ current inactivation. In paper II and III, we have investigated the effects of miRNA modulation on insulin secretion and exocytosis. First we investigated miRNA-regulation of voltage-gated Na+ channels since their role in beta cell function is not yet clear. Down-regulation of miR-375 differentially affected Na+ channel inactivation properties in INS-1 832/13 cells and miR-375 knock-out mice beta cells, suggesting species differences. As steady-state inactivation determines the number of channels available for generation of action potential, this study is a proof of principle that mir-375 could be important in regulating electrical activity in human beta cells. Next, miRNA-regulation of the exocytotic process was investigated. Overexpression of miR-335 reduced exocytosis and thereby insulin secretion through decreased expression of the exocytotic proteins STXBP1, SNAP25 and SYT11. In this paper I also made the novel observation that SYT11 increase basal insulin secretion and decrease rapid exocytosis, two phenomenons associated with T2D. The work on miR-335 emphasizes the importance of miRNAs in the regulation of the exocytotic process. In paper IV and V the effects of the cholesterol-lowering drug rosuvastatin was investigated. Rosuvastatin treatment dose dependently affected Ca2+ influx, exocytosis, basal and glucose-induced insulin secretion in INS-1 832/13 cells. Interestingly, most of this effect was though mevalonate pathway and not from the cholesterol lowering ability of rosuvastatin. In vivo rosuvastatin had an overall positive effect on glucose homeostasis in mice but negative effects on beta cell function such as disturbed Ca2+-signalling.&lt;br/&gt;&lt;br&gt; In conclusion, the data in my thesis demonstrate the need for investigations of the mechanisms behind defective insulin secretion and exocytosis in order to understand and treat T2D.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; När vi äter ökar nivån av blodsocker (blodglukos) i blodet. Glukos forslas i blodet till målvävnader, såsom fett och skelettmuskel, där det används som energi. Men för att glukos ska kunna tas upp av målvävnaden krävs insulin. Insulin är ett hormon som produceras av beta-celler i bukspottkörtelns Langerhanska öar, vars sekretion ut i blodet regleras av blodglukos. Då denna process misslyckas förmår inte kroppen att sänka blodglukos tillräckligt. Detta leder till utveckling av typ 2 diabetes, som är en kombination av beta-cellernas oförmåga att frisätta tillräcklig mängd insulin och målvävnadens oförmåga att ta upp glukos. &lt;br/&gt;&lt;br&gt; I denna avhandling har jag undersökt mekanismer som påverkar insulinsekretion och då framförallt en process som benämns exocytos. I beta-cellen fylls små runda blåsor, sk granula med insulin, då insulinet väl har producerats. Exocytos är den process varmed dessa granula smälter samman med det omgivande membranet på beta-cellen för att insulinet ska komma ut i blodet. Ökad koncentration av glukos är en grundläggande faktor för att exocytos ska ske och insulin utsöndras. Jag har specifikt fokuserat på tre faktorer som kan påverka exocytos-processen i beta-cellen och därmed också insulinsekretionen och nivån av glukos i blodet. Dessa är calcium, microRNA och rosuvastatin.&lt;br/&gt;&lt;br&gt; Kalcium är den molekyl som initierar fusionen av granula med det omgivande membranet. Jag har i min avhandling på detaljerad cellulär fysiologisk nivå med hjälp av en matematisk modell studerat detaljer i förhållandet mellan kalcium och fusionen av granula, som har medfört ökad förståelse för den här processen. En viktig del i denna studie är att jag tagit tillvara att enskilda celler är heterogena, något som inte tidigare gjorts i liknande studier.&lt;br/&gt;&lt;br&gt; MicroRNA är små molekyler som reglerar mängden av protein i cellen. Då en cell har mycket av ett microRNA så minskar mängden av protein som detta microRNA specifikt reglerar. Dessa molekyler har föreslagits kunna fungerar som biomarkörer då halten av specifika microRNA förändras vid uppkomst av sjukdom. MicroRNA är ofta vävnads-specifika och därför har reglering av mängden microRNA också förslagits kunna användas som läkemedel. Jag har studerat två microRNA, miR-375 och miR-335, och hur de reglerar mängden specifika protein, som påverkar sekretionen av insulin och exocytos-processen. I min avhandling fann jag att miR-375 reglerar beteendet hos en spänningskänslig jonkanal som forslar natrium in i cellen. Vidare fann jag att överuttryck av miR-335 påverkar mängden av tre olika protein som medverkar i exocytos-processen. Det sistnämnda är extra intressant eftersom det tidigare har visats att mängden miR-335 är förhöjd i diabetiska djurmodeller och mängden av flera proteiner som medverkar vid exocytos-processen är reducerad i Langerhanska öar vid typ 2 diabetes. &lt;br/&gt;&lt;br&gt; Rosuvastatin är en statin som används för behandling av kardiovaskulära sjukdomar för att sänka kolesterolnivån. På senare tid har det via flera studier framkommit att medicinering med statiner medför en ökad risk att få diabetes. För att undersöka detta närmare har jag i min avhandling undersökt hur rosuvastatin påverkar exocytos-processen, sekretion av insulin och blodglukosnivåer. Jag fann att rosuvastatin minskade insulinsekretionen och påverkade nivåerna av kalcium inne i cellen. Vidare hade rosuvastatin en positiv effekt på upptaget av glukos i målvävnad, och åtminstone under den period som vår studie pågick förändrades inte blodglukosnivåerna. Den minskade insulinsekretionen kan dock på längre sikt komma att öka glukoshalten i blodet. Detta får framtida studier visa.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar jag i min avhandling vikten av en fungerade exocytos-process för fungerande sekretion av insulin. Genom denna kunskap har ytterligare en pusselbit lagts till det pussel som behöver läggas för att vi ska få en ökad förståelse av hur insulin utsöndras och hur defekter i denna process leder till typ 2 diabetes. Nödvändigt för en framtida förbättrad behandling av sjukdomen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;b&gt;Popular Abstract in Uncoded languages&lt;/b&gt;&lt;br/&gt;&lt;br&gt; आपण जे काही खातो त्या मुळे रक्ता तील साखरे (ग्लुकोस) चे प्रमाण वाढते. शरीराला उपयुक्त अशा या साखरेचे परिवहन शरीराच्या विभिन्न भागात केले जाते; उदाहरणार्थ: चरबी, विविध स्नायू इत्यादी., जिथे तीचा वापर उर्जा स्त्रोत म्हणून केला जातो. परंतु ही साखर शरीरा मध्ये शोषून घेण्या साठी इन्सुलिन नावाच्या संप्रेरकाची गरज भासते. इन्सुलिन नावाचे हे संप्रेरक स्वादुपिंडा तिल बीटा पेशी द्वारे तयार केले जाते. इन्सुलिन चा रक्तातील प्रादुर्भाव हा शरीरातील साखरे च्या प्रमाणा वर अवलंबून असतो. मानवी शरीरातील हि एक सर्व सामान्य प्रक्रिया आहे, या प्रक्रिये मध्ये काही बिघाड झाल्यास, शरीर रक्तातील साखरेचे प्रमाण नियंत्रित करू शकत नाही. पुढे जाऊन याचे रुपांतर मधुमेह-प्रकार-२ नावाच्या आजारात होते. या आजारा मध्ये स्वादुपिंडा तील बीटा पेशी इन्सुलिन तयार करण्यास असमर्थ असतातच त्याच बरोबर शरीरातील स्नायू सुद्धा इन्सुलिन शोषून घेण्यास असमर्थ होऊन जातात.&lt;br/&gt;&lt;br&gt; प्रस्तुत शोधनिबंधा मध्ये; इन्सुलिन बनविण्याच्या सर्व सामान्य प्रक्रियेवर बाधा आणणारे घटक आणि विशेषत: एक्सोसायटोसीस (शरीरातील एक प्रक्रिया: ज्या द्वारे पेशी मधील घटक द्रव्य काही कारणास्तव पेशी बाहेर काढले जातात); या विषया वर मी संशोधन केले. बीटा पेशी मध्ये तयार झालेले इन्सुलिन, छोट्या फुग्या सारख्या आकारामध्ये साठवले जाते; त्याला इन्सुलिन चे गोळे असेही म्हणतात. त्या नन्तर एक्सोसायटोसीस च्या प्रेक्रीये द्वारे इन्सुलिन चे गोळे बीटा पेशी च्या बाह्य आवरणा तून पेशी च्या बाहेर रक्ता मध्ये सोडले जातात. शरीरा मध्ये अवास्तव वाढलेली साखर हे एक्सोसायटोसीस प्रक्रियेला चालना देणार आणि इन्सुलिन च्या निर्मितीला भाग पाडणार मूळ कारण आहे. माझ्या संशोधना मध्ये मी प्रामुख्याने तीन घटकांचा अभ्यास केला ते म्हणजे; कॅल्शियम, लघु-आर.एन.ए., रोसुवास्तातीन. कारण की या तीनही घटकांमध्ये; एक्सोसायटोसीस प्रक्रिया- त्यावर अवलंबून असणारी इन्सुलिन निर्मिती प्रक्रिया आणि रक्तातील साखरे च प्रमाण; या महत्वाच्या गोष्टी वर परिणाम करण्याची क्षमता आहे.&lt;br/&gt;&lt;br&gt; कॅल्शियम या पदार्था मुळे वेग-वेगळे गोळे सभोवतालच्या आवरणास चीकटन्यास मदत होते. मी गणिती पद्धतीने अभ्यास करून कॅल्शियम चे प्रमाण आणि इन्सुलिन चे गोळे यांच्या तील परस्परसंबंध विस्तृत पणे तपासला. विशेष म्हणजे या अभ्यासा मध्ये &quot;प्रत्येक पेशी ही विभिन्न प्रकार ची असु शकते&quot; हि गोष्ट विचारात घेण्यात आली. आमच्या माहिती प्रमाणे अशाप्रकारचा प्रयोग आम्हीच सर्व प्रथम करत आहोत.&lt;br/&gt;&lt;br&gt; लघु आर.एन.ए.: हे लहान असे पदार्थ पेशी मधील एखाद्या ठराविक प्रथिना चे प्रमाण कमी-जास्त करू शकतात. जर एखाद्या पेशी मध्ये एखाद्या ठराविक प्रथिन चे जास्त लघु आर.एन.ए. असतील तर ते त्या ठराविक प्रथिना ची संख्या कमी करतात. त्याच मुळे विशिष्ट आजाराशी संलग्न असलेल्या लघु आर.एन.ए चा वापर त्या विशिष्ट आजाराचे निदान करण्या साठी होऊ शकतो. लघु आर.एन.ए. सहसा विशिष्ट स्नायू साठीच कार्यरत असतात, म्हणूनच लघु आर.एन.ए. च्या प्रमाणा वर नियंत्रण मिळवून आपण त्याचा उपचार करण्या साठी वापर करू शकतो. मी; मीर-३७५ व मीर-३३५ हे दोन लघु आर.एन.ए. तपासले, हे दोघे एखाद्या प्रथिना च्या निर्मिती मध्ये कसा व्यवहार करतात?

Additionally some initial estimates of the carbon input to the atmosphere of nonmethane hydrocarbons (NMHCs) were also obtained by combining different techniques in a joint setting. The data presented were collected at the Stordalen mire, a palsa type complex located in the northernmost part of subarctic Sweden (68°20’N, 19°03’E, alt. 363 m asl). This site represents an ecosystem type that is highly sensitive to climatic conditions, especially to the ongoing processes of climate warming. Recent studies performed in this area have shown that those ecosystems in northern Scandinavia are subject to dramatic changes, as the distribution of permafrost is diminishing and vegetation is changing, which has been triggered by warming over recent decades. These regional landscape changes are affecting the ecosystems carbon balance, and might determine whether these ecosystems will be classified as either greenhouse gas sources or sinks. In addition to the obtained estimates of the emission of the two major greenhouse gases (CO2 and CH4), the quantitative studies of NMHCs were derived by simultaneously performed chamber measurements coupled with total hydrocarbon (THC) analyses, and by applying a disjunct eddy covariance (DEC) technique to measure specific emissions of isolated biogenic volatile organic compounds (BVOCs) such as isoprene and methanol.&lt;br/&gt;&lt;br&gt; The measured eddy covariance tower net ecosystem exchange (NEE) showed a strong and consistent annual uptake signal. During the years 2004 to 2008, with relatively comparable climates the annual NEE amounts to -89 g CO2-C m-2 y-1, with very small variation. The eddy covariance (EC) tower acquired CH4 flux measurements and showed a strong positive input to the annual carbon budget in the range of 18-22 g CH4-C m-2 y-1, reducing the studied ecosystem sink strength by almost 20%. Additional positive budget components in the form of emission of NMHCs constitute roughly an additional 15% to the CH4 fluxes. This fraction may be compared with the EC CH4 flux measurements emission rates and the results of the isoprene and methanol flux measurements obtained by the DEC method. Here the proportional atmospheric emission is estimated as 4% and 1% respectively for the above-mentioned components, indicating that other compounds must be responsible for a large proportion of the NMHC flux. By applying a global warming potential factor and calculating the annual balances expressed in CO2 equivalent numbers converted according to a 100 year time horizon, the degrading parts of the Stordalen mire appear as a greenhouse warming source with a level of emission estimated at +93 g CO2equiv.-C m-2 y-1. This strong greenhouse warming source demonstrates the necessity of conducting detailed carbon budgeting experiments that will lead to an improvement of our understanding of how global carbon cycling interacts with climate.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5cbfba83-b313-46f6-a91e-586e0c33268f</url> </location> </relatedItem> <originInfo> <publisher>GeoBiosphere Science Centre, Department of Physical Geography and Ecosystems Analysis, Lund University, Sölvegatan 12, 223 62, Lund, Sweden</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>eddy covariance</topic> <topic>chamber</topic> <topic>methnaol</topic> <topic>isoprene</topic> <topic>nonmethane hydrocarbons</topic> <topic>methane</topic> <topic>carbon dioxide</topic> <topic>carbon</topic> <topic>mire</topic> <topic>permafrost</topic> <topic>subarctic</topic> <topic>palsa</topic> <topic>greenhouse gas</topic> </subject> <subject authority="lup"> <topic>Physical Geography</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Meddelanden från Lunds universitets geografiska institution.

Projects, though, are temporary in nature and this has consequences for the organization that uses them as a business strategy to improve its efficiency. Project-based organizations are representative of this organizational form and can either be standalone or subsidiary organizations within a larger corporation. In project-based organizations the majority of products or services are produced through projects for either internal or external customers. Nevertheless, project-based organizations are characterized as loosely coupled systems with independent sub-units resulting in sparse internal knowledge processes and capability development.&lt;br/&gt;&lt;br&gt; Real estate organizations are often composite organizations where one part is project-based with a temporary perspective, and the other parts perceive the organization to have a longer term perspective, represented by facility management, asset management, maintenance, operational services etc. Real estate organizations thus often maintain a long-term relationship with customers and end-users, although are frequently found to be lacking in their management of end-users. Moreover, they are often found to have inadequate competence in project management and in connecting their business and project networks, resulting in inefficient use of resources.&lt;br/&gt;&lt;br&gt; The present research investigates how practices in project-based organizations impact upon internal knowledge processes and capability development with the aim of fulfilling end-users’ needs and requirements. The research question is formulated as follows: how do project-based organizations’ underlying mechanisms impact on internal knowledge processes? This is investigated through a knowledge-based view of project-based organizations and explores it from the bottom up through the organizational hierarchies, that is, from the interaction with end-users in projects, through the project management office and up to top-management and its knowledge governance strategies. The research adopts a critical realism perspective, holds knowledge processes as the unit of analysis and combines literature reviews with 14 qualitative case studies and a final qualitative sample survey, and is published in five peer-reviewed research journal papers.

Varför är vissa organisationer fantastiska på kundhantering medans andra är fenomenala i tekniskt relaterade produktfrågor? Redan de gamla grekerna diskuterade kunskap och lärande och ämnet fascinerar fortfarande forskare. Sofia Pemsel, lägger i dagarna fram sin doktorsavhandling: Knowledge processes and capabilities in project-based organisations. Avhandlingen undersöker vilka underliggande mekanismer som triggar igång kompetens och kunskapsutveckling i projektbaserade organisationer i fastighetssektorn.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Kunskapsmäklare och Governacne strategier för kunskap &lt;br/&gt;&lt;br&gt; Hantering utav brukare och kunder är en kärnkompetens fastighetsföretag ständigt bör utveckla för att överleva på marknaden. I interaktionen med brukare i projekt uppkommer ett flertal barriärer och svårigheter professionella måste överbrygga för att få till en effektiv process och i slutändan nöjda kunder. För att hantera dessa barriärer utvecklar ofta professionella aktörer olika strategier, roller och metoder för att förstår brukarnas behov och kravbild i byggprojekt. Dock förblir dessa kunskaper och kompetenser ofta personbundna vilket, ur ett företagsstrategiskt perspektiv, är en riskfaktor. För att förbättra interna kunskapsprocesser i projektbaserade organisationer implementerar ofta fastighetsföretag så kallade projektkontor med uppgift att agera kunskapsmäklare. Projektkontorens förmåga att agera kunskapsmäklare varierade dock avsevärt mellan organisationerna som ingick i denna studie. I vissa organisationer kämpade projektkontorets personal i ständig motvind medans i andra fall lyckades de vinna projektledarnas tillit och kan anses vara ”framgångsrika” kunskapsmäklare, i alla fall avseende vissa kompetensområden. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Forskningen påvisar bland annat att fastighetsföretagen i denna studie utvecklat olika Governance strategier för kunskap. Governance strategierna nyttjades för att trigga igång interna kunskapsprocesser och visas vidare vara en del utav ett flertal samspel i organisationen mellan faktorer såsom tacit – explicit kunskap, individuell – kollektivt hållen kunskap, konsultativa och coachande – lagsättande approacher, projekt – affärsmål, strategier avseende exploration – exploitation processer, formellt – informellt ledarskap, favoriserandet utav kunskapskodning, kunskapsartikulerande eller kunskapsackumulerande aktiviteter etc. Vissa företagsstrategier trycker hårdare på endera faktorn i dessa samspel vilket denna forskning visar får konsekvenser för företagets övergipande kompetensutveckling. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studien bygger på litteraturstudier samt empiriskt material bestående av 100 semistrukturerade intervjuer, 17 workshops och möten med forskare och företagsrepresentanter samt dokumentanalyser i företag i fastighetssektorn i Australien, Finland och Sverige.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d6546251-facc-4fb6-b99b-993992af432e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Sofia_Pemsel_HELA__3_.pdf">https://portal.research.lu.se/files/3270842/2542701.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">27790225</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>PBO</topic> <topic>project</topic> <topic>knowledge process</topic> <topic>capabilities</topic> <topic>end-user</topic> <topic>real estate sector</topic> <topic>PMO</topic> <topic>knowledge governance</topic> <topic>bridging boundaries</topic> <topic>critical realism</topic> </subject> <subject authority="lup"> <topic>Construction Management</topic> </subject> <relatedItem type="host"> <titleInfo> <title>ISRNLUTVDG/TVBP--12/1036--SE</title> </titleInfo> <identifier type="issn">1651-0380</identifier> <identifier type="oldLupId">2542696</identifier> <part> <extent unit="pages"> <total>240</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-06-15T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>d6546251-facc-4fb6-b99b-993992af432e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:35+02:00</recordDateApproved> </recordInfo> </mods>

Despite extensive studies in the field, a comprehensive&lt;br/&gt;&lt;br&gt; understanding of this syndrome has remained elusive, partly due to divergent definitions of AKI and partly due to&lt;br/&gt;&lt;br&gt; the limitations of available routine biomarkers to predict, prevent, and detect AKI. In recent years, much has been&lt;br/&gt;&lt;br&gt; done to better define AKI. There is also ongoing work on finding better suited biomarkers for AKI as well as&lt;br/&gt;&lt;br&gt; improving treatment of patients at risk or suffering from AKI.&lt;br/&gt;&lt;br&gt; In this work we studied different aspects of renal function after cardiac surgery.&lt;br/&gt;&lt;br&gt; The first paper shows in a retrsospective study of 5261patients, when preoperative estimated glomerular filtration&lt;br/&gt;&lt;br&gt; (eGFR) rate by s-creatinine and preoperative hemoglobin is entered into a Cox analysis together with known&lt;br/&gt;&lt;br&gt; traditinoal risk factors for decreased long-term survival, blood transfusion did not affect survival significantly. In&lt;br/&gt;&lt;br&gt; the subgroups of patients with normal eGFR and hemoglobin, blood transfusions did not have any effect on longterm&lt;br/&gt;&lt;br&gt; survival.&lt;br/&gt;&lt;br&gt; In the second paper, incidence of AKI is evaluated in 5746 patients, defined by different measures (i.e creatinine,&lt;br/&gt;&lt;br&gt; creatinine clearance and eGFR) and evaluated in relation to long-term mortality. The effect of renal recovery on&lt;br/&gt;&lt;br&gt; survival was also described. The Risk, Injury, Failure, Lost and Endstage (RIFLE) system was used to stratify&lt;br/&gt;&lt;br&gt; AKI. The study showed that estimated GFR by the modification of diet in renal disease (MDRD) formula had a&lt;br/&gt;&lt;br&gt; more robust predictive ability for mortality and that renal recovery in general was associated with better outcome&lt;br/&gt;&lt;br&gt; compared with those without renal recovery.&lt;br/&gt;&lt;br&gt; The third paper describes a randomized, double-blind, placebo-controlled trial, where the effect of a single high&lt;br/&gt;&lt;br&gt; dose erythropoeitin (EPO) preoperatively, as a protective drug against AKI after cardiac surgery, is evaluated.&lt;br/&gt;&lt;br&gt; Seventy five patients were enrolled in the study, AKI was evaluated by the changes of s-cystatin C at the third&lt;br/&gt;&lt;br&gt; postoperative day from baseline. No protective effect against AKI by EPO could be shown.&lt;br/&gt;&lt;br&gt; In the fourth paper the predictive value for mortality of s-creatinine and s-cystatin C and their eGFR were&lt;br/&gt;&lt;br&gt; evaluated at different time points in patients undergoing cardiac surgery. The prospective study included 1955&lt;br/&gt;&lt;br&gt; patients. Different creatinine and cystatin C eGFR equations were used in the analysis. S-Cystatin C was shown&lt;br/&gt;&lt;br&gt; to have a stronger and earlier predictive value for mortality compred with s-creatinine, and the predictive abliltiy&lt;br/&gt;&lt;br&gt; of cystatin C was also shown preoperatievly.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Njurfunktion inom hjärtkirurgi&lt;br/&gt;&lt;br&gt; Akut njursvikt (AKI) efter hjärtkirurgi är en allvarlig komplikation som förekommer i 25-35 % av alla patientfall. AKI medför förhöjd risk för allvarliga komplikationer och död efter hjärtkirurgi. Ett stort fokus ligger på detektion, prevention och behandling av AKI och forskningsfältet uppdateras kontinuerligt. En rad olika läkemedel har provats i samband med hjärtkirurgi i syfte att skydda&lt;br/&gt;&lt;br&gt; njurfunktionen men hittills har ingen av dessa visat någon säker positiv effekt. Njurfunktionen har traditionellt mäts med ett blodprov med mätning av kreatininnivåer i blodet. Kreatinin är en biprodukt av ämnesomsättningen i kroppens muskler och filtreras via njurarna i urinen. En av njurens viktigaste uppgifter är att filtrera ut små molekyler. Denna filtrationsförmåga kallas glomerular filtration, och mäts i en glomerular filtration rate - GFR. GFR speglar hur väl njurarna fungerar. Nedsatt njurfunktion leder till minskad filtrationsförmåga och följaktligen stegrade kreatinin-nivåer i blodet. Denna stegring tyder vanligtvis på nedsatt njurfunktion. Vid en normal njurfunktion krävs det dock en 50 % nedsättning av njurfunktion för att kreatinin-nivåerna ska stiga. Detta är en av bristerna med kreatinin som markör för njurfunktion vilket innebär att det tar tid innan njurfunktionsnedsättning kan upptäckas. Kreatinin har även andra brister som njurfunktionsmarkör, varför forskning pågår för att hitta bättre markörer. Det bör dock nämnas att kreatinin i dagsläget, trots allt är den vanligaste njurfunktionsmarkören i kliniskt bruk. För att bl.a. kunna definiera graden av AKI och driva forskningen framåt har det skapats internationell definitioner och klassificeringar för AKI. En av de vanligaste klassificeringarna kallas för RIFLE som är beroende av kreatinin-stegring i blodet eller graden av GFR-sänkning. En annan njurfunktionsmarkör är cystatin C, denna är en kroppsegen substans som upptäckts i Lund för ca 30 år sedan och presenterats som en bättre njurfunktionsmarkör jämfört med kreatinin. Cystatin C har inte de brister som kreatinin har och kan möjligen ge mer tillförlitlig information om njurens funktion. I kliniskt arbete anser man att det är viktigt att även ange GFR värdet när man utvärderar njurfunktion och inte enbart värdet av njurfunktionsmarkören. Detta är oftast ett uträknade värde genom formler som baseras på kreatinin eller cystatin Cnivåer i blodet. Det finns ett flertal sådana formler. Utöver kostnads- och tillgänglighetsaspekter råder även oenighet om vilken njurfunktionsmarkör och via vilken formell man bör bedöma njurfunktionen. Genom att optimera njurfunktionsmätningar i tid och precision kan progress av njursjukdomen i samband med hjärtkirurgi begränsas, förebyggas eller behandlas. &lt;br/&gt;&lt;br&gt; Avhandlingens delarbeten&lt;br/&gt;&lt;br&gt; Delarbete 1.&lt;br/&gt;&lt;br&gt; Blodtransfusion har generellt sett ansetts medföra en ökad risk för komplikationer och även öka risken för långtidsmortalitet i samband med hjärtkirurgi. I delarbete I har interaktionen mellan njurfunktion och transfusion med avseende på långtidsmortalitet studerats. I detta arbete kunde vi visa att blodtransfusion efter hjärtkirurgi är associerat till sämre överlevnad. Men när hänsyn togs till patientens njurfunktion och blodvärde före operation minskade risken med blodtransfusioner. När enbart patienter med normal njurfunktion och normalt blodvärde före operation studerades sågs ingen påverkan på överlevnad på sikt av blodtransfusioner jämfört med patienter som inte fått blodtransfusioner &lt;br/&gt;&lt;br&gt; Delarbete II&lt;br/&gt;&lt;br&gt; I detta delarbete studeras riskerna med akut njursvikt efter kranskärlskirurgi. Kreatinin samt två vanliga formler för beräkning av GFR baserat på kreatinin-nivåer i blodet studerades och jämfördes för över 5000 patienter vid olika tidpunkter före och efter operation. Data kategoriserades enligt det s.k. RIFLE systemet och effekten på återhämtning av njurfunktionen sattes i förhållande till långtidsöverlevnad. I denna studie visades att GFR-beräkning (jämfört med kreatinin) kan&lt;br/&gt;&lt;br&gt; vara mer informativ ur prognostisk synpunkt samt att den sämsta njurfunktionen är den som starkast är kopplad till minskad överlevnad, samtidigt som återhämtning av njurvärden allmänt sett är positivt ur överlevnadssynpunkt.&lt;br/&gt;&lt;br&gt; Delarbete III&lt;br/&gt;&lt;br&gt; I dagsläget finns inget läkemedel som visats kunna skydda njurarna mot akut njursvikt vid hjärtkirurgi. Erythropoietin (EPO) är ett kroppseget hormon som är känt för att stimulera produktionen av röda blodkroppar. EPO har i många djurstudier samt i några kliniska studier kunnat visas ha skyddande effekt mot syrebrist kroppsorgan. I detta delarbete studerades effekten av EPO given innan operation i syfte att studera en eventuell skyddande effekt mot akut njursvikt hos patienter som redan innan operation har större risk att utveckla akut njursvikt pga. habituellt nedsatt njurfunktion. Patienterna randomiserades till EPO och placebo. Gruppen som fick EPO uppvisade inga tecken på att ha fått njurskyddande effekter av det administrerade läkemedlet. &lt;br/&gt;&lt;br&gt; Delarbetet IV&lt;br/&gt;&lt;br&gt; Betydelsen av cystatin C inom intensivvård och hjärtkirurgi är inte fullständigt studerat. Cystatin C prognostiska förmåga för att förutsäga komplikationer och död i jämförelse med kreatinin är okänt för hjärtopererade patienter. I detta delarbete har cystatin C och kreatinin samt GFR beräkningar baserad på dessa jämförts inbördes hos närmare 2000 patienter som genomgått hjärtkirurgi och satts i relation till långtidsöverlevnad. I denna studie visas att cystatin C och dess GFR beräkningar har en starkare prognostisk värde jämfört med kreatinin för överlevnad efter hjärtoperation. Det prognostiska värdet kan avläsas i ett tidigare skede jämfört med kreatinin. Ur klinisk synpunkt medför detta att cystatin C och dess GFR beräkningar kan redan före operation indikera vilka patienter som är riskpatienter och som behöver extra tillsyn avseende njurfunktionen efter en hjärtoperation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f67f748c-1572-4cfb-aa5c-cf47820f1234</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Alain_Daradshti_spikning.pdf">https://portal.research.lu.se/files/3271122/4810413.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">6146479</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Acute kidney injury</topic> <topic>eGFR</topic> <topic>Transfusion</topic> <topic>Mortality</topic> <topic>Erythropoietin</topic> <topic>Cardiac surgery</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>ISBN 978-91-7619-074-6</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="oldLupId">4810402</identifier> <part> <detail type="volume"> <number>1</number> </detail> <extent unit="pages"> <total>91</total> </extent> </part> </relatedItem> <note type="teachingLearningHe">yes</note> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-20T13:45:00+01:00</dateOther> <recordInfo> <recordIdentifier>f67f748c-1572-4cfb-aa5c-cf47820f1234</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:39+02:00</recordDateApproved> </recordInfo> </mods>

NAFLD has a multi-factorial aetiology, both genetic and environmental factors are equally important. The aim of this thesis was to investigate genetic factors associating with NAFLD and circulating triglyceride (TG) levels in overweight or obesity and their interaction with diet, as well as their association with lipid and glucose traits, and incidence of T2D and CVD. In total 417 obese Finnish subjects and &amp;gt;5000 subjects from the population-based prospective Malmö Diet and Cancer Study (MDCS), with data on genotypes, lipid traits and diet, were included. Two apolipoprotein c3 (APOC3) variants did not associate with liver fat content or apoc3 concentrations among Finns, which was in contrast to results in a previous study. Overweight modified the association between the PNPLA3 rs738409 and TG and ALAT levels (Pinteraction=0.003 and 0.03, respectively) and we additionally observed that carbohydrate (CHO) and fat intakes, in particular sucrose among normal-weight individuals, and possibly the ω-6: ω-3 PUFA ratio in overweight individuals, may modify association with TG levels (Pinteraction=0.03 and 0.08, respectively). Importantly, our results suggest that the&lt;br/&gt;&lt;br&gt; mechanism by which PNPLA3 variant increases liver fat accumulation may depend on BMI status and dietary intake. The variants in MLXIPL and GCKR genes, were associated with lower TG and higher glucose traits in&lt;br/&gt;&lt;br&gt; MDCS-CC study, and a combination of TG lowering alleles in MLXIPL and GCKR was strongly associated with lower TG levels (P=2.4-12) and higher fasting glucose and HbA1c levels (P=0.009, for both). The same alleles associated with lower risk of hypertriglyceridemia at the baseline (P=0.015 for MLXIPL, P=0.00025 for GCKR and P=0.000012 for combined alleles), and the MLXIPL T-allele was associated with lower incidence of hypertriglyceridemia in the prospective analysis (OR: 0.37; 95%CI: 0.20-0.70; P=0.002).These loci did not associate with the risk of T2D, although a nominally significant interactions between total CHO intake and MLXIPL and between fiber intake and GCKR on T2D risk was observed (Pinteraction=0.043, Pinteraction=0.007, respectively). Analysis of combined genotypes reflected the results observed in the interaction analyses for the individual genotypes. Additionally, five NAFLD susceptibility loci did not show any association with T2D, CVD or total mortality, except for that nominally significant associations between the GRS and increased incidence of T2D (P=0.03) and death (P=0.048) was observed among severely obese (BMI≥35kg/m2) individuals. In conclusion, this thesis suggests putative role of obesity and dietary CHOs in modifying the genetic susceptibility to NAFLD, which may facilitate further studies to elucidate the mechanisms and factors behind increased liver fat&lt;br/&gt;&lt;br&gt; accumulation and potential new therapeutic approaches.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f71a6ba4-3443-44af-abd0-30b8b6f0e291</url> </location> </relatedItem> <originInfo> <publisher>Diabetes and cardiovascular disease - genetic epidemiology</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>NAFLD</topic> <topic>genetic variations</topic> <topic>triglycerides</topic> <topic>ALAT</topic> <topic>dietary intake</topic> <topic>type 2 diabetes</topic> <topic>cardiovascular disease</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-111-8</identifier> <identifier type="oldLupId">5275543</identifier> <part> <detail type="volume"> <number>2015:32</number> </detail> <extent unit="pages"> <total>156</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-04-10T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f71a6ba4-3443-44af-abd0-30b8b6f0e291</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:40+02:00</recordDateApproved> </recordInfo> </mods>

The present study, in contrast, argues for continuity between the socialist period and the post-refrom era in China&apos;s economic course.&lt;br/&gt;Chinse socialism, it is argued, should best be understood as a strategy of industrialization which, in absence of a modern agricultural sector, had t proceed with more stringent institutional arrangements. the particular features of China&apos;s socialist agriculture, namely the rural Communes, were crucial for making up for the missing contributions of the agriculatutal sector in the process of industrialization. The Communes, by merging agricultural activity with rural industry, eventually managed to produce the modern agricultural inputs crucial for the increase of productivity in agriculture. Once the technological breakthrough was there, the collectivist institutions of rural China served no purpose in the inductrializatiion process. The transition to market and private agriculture became feasible in the new context of a modern, productive agriculture.&lt;br/&gt;The model elaborated here for China&apos;s transition has relevance for the study of the industrialization process in other Third World countries which show less stringent forms of deviation from market than the socialist strategy of industrialization in China.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a400864b-b1a1-40c4-ba8f-1bf76f84e887</url> </location> </relatedItem> <originInfo> <publisher>School of Economics and Management, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>industrialization</topic> <topic>China</topic> <topic>transition</topic> <topic>socialism</topic> <topic>market</topic> <topic>economic history</topic> <topic>economic development</topic> <topic>agriculture</topic> <topic>åproductivity</topic> <topic>rural industry</topic> <topic>development strategy</topic> <topic>Third World</topic> <topic>Gerschenkron</topic> </subject> <subject authority="lup"> <topic>Economics and Business</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in Economic History</title> </titleInfo> <identifier type="issn">1400-4860</identifier> <identifier type="oldLupId">2278258</identifier> <part> <detail type="volume"> <number>57</number> </detail> <extent unit="pages"> <total>191</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-01-28T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>a400864b-b1a1-40c4-ba8f-1bf76f84e887</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:47+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:47+02:00</recordDateApproved> </recordInfo> </mods>

Here we define a role for the hypoxia inducible factor-2α in neuroblastoma tumor progression. While HIF-1α was transiently stabilized at hypoxia (1% oxygen), HIF-2α was induced and regulated HIF-specific target genes, such as VEGF, at later time points. Furthermore, HIF-2α was stabilized and transcriptionally active in cells grown at physiological oxygen levels (5% O2). Subsequent microarray analysis showed that HIF-2α induced genes, previously identified as hypoxia regulated, at this physiological oxygen level. Several of these genes have been implicated in tumorigenic processes and correlated to adverse patient outcome in various tumor forms. Indeed, siRNA mediated knock-down of HIF-2α in neuroblastoma cells significantly reduced xenograft tumor growth, as compared to siHIF1-α treated or wild-type cells. Moreover, immunohistochemical analyses of a large neuroblastoma tumor material arranged in a tissue microarray showed that HIF-2α expression correlated to VEGF, and that high HIF-2α levels was predictive of poor patient prognosis.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Prognostic markers of neuroblastoma patient adverse prognosis include amplification of the MYCN oncogene and an undifferentiated morphology. While these features discriminate high- from low-risk patients with precision, identification of poor outcome low- and intermediate-risk patients is more challenging. We analyze two large neuroblastoma microarray data sets by using a priori-defined gene expression signatures. The results show that differential overexpression of Myc transcriptional targets and low expression of genes involved in sympathetic neuronal differentiation predict relapse and death from disease. This was evident not only for high-risk patients, but also was robust in identifying groups of poor prognosis patients otherwise judged to be at low- or intermediate-risk for adverse outcome. These data suggest that pathway-specific gene expression profiling might be useful in the clinic to adjust treatment strategies for children with neuroblastoma.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a57aae3b-39d1-4ebb-8b39-da5eb9334082</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Erik_Fredlund_kappa__100.pdf">https://portal.research.lu.se/files/3274711/1045365.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1767679</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University Press</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>microarray</topic> <topic>hypoxia</topic> <topic>MYCN</topic> <topic>gene expression analysis</topic> <topic>Neuroblastoma</topic> <topic>Myc</topic> <topic>pathway analysis</topic> <topic>differentiation</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-82-7</identifier> <identifier type="oldLupId">1045359</identifier> <part> <detail type="volume"> <number>2008:29</number> </detail> <extent unit="pages"> <total>150</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-03-28T09:15:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The thesis has given the IPS-participants an active voice about what it is like to start to work in a Swedish context, visualised the psychiatric disability in relation to work, discerned the support and process in IPS, and emphasized the employers’ experiences in an IPS-context. Study I, a multiple case study, aimed to discern the support and process in IPS that involved job-search support, job-matches, adjustment of the match by providing accommodations by on- and off-worksite support, and organizing an individually adapted IPS-network. The initial job-match was an important factor for increasing or decreasing job-tenure among the IPS-participants. The social work environment was an important accommodation area. Previous work experience, disclosure, and not being in an acute phase of the illness were important for utilization of IPS. The qualitative interview Study II explored the IPS-participants’ perceptions of their worker role and work environment. Work had mostly a positive impact on daily life, although it was a struggle to fit in and the mental illness affected work performance. They perceived supportive and demanding factors in their work environments, such as the employer’s support and the social atmosphere among colleagues. Own personal strategies were needed to cope. The cross-sectional Study III studied the relationships between cognitive functioning, communication and interaction skills, and vocational outcomes among people with SMI attending vocational services for 18 months. Higher scores in planning, reasoning and problem solving best explained the variation in having competitive employment or not, and correlated with increased hours and weeks in competitive employment. Higher scores in delayed verbal recall correlated with having a higher income. Communication and interaction skills differed between the groups of employment status and correlated with hours and weeks in competitive employment, higher income, and higher scores in delayed verbal recall. Study IV, a grounded theory situational analysis study, showed that the employers strove to maintain their social commitment throughout the process from taking on IPS-service users to supporting them at work. The employment specialist’s trustworthiness and professional approach, as well their at-work support was considered crucially important for the employers’ readiness to open the door. In conclusion, the organization of the IPS, and the articulation of the support and process in IPS may be important to address in order to increase job-tenure and employment success among IPS-participants.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c896975b-36cc-4445-bf66-4973f55f73ac</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Annika_lexen_140126_FINAL.pdf">https://portal.research.lu.se/files/3274735/4316672.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1261767</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Supported employment</topic> <topic>PEO-model</topic> <topic>work accommodations</topic> <topic>vocational rehabilitation</topic> <topic>severe mental illness</topic> <topic>schizophrenia</topic> <topic>clinical implications</topic> <topic>cognitive functioning</topic> <topic>communication and interaction skills</topic> <topic>employer experiences</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-48-9</identifier> <identifier type="oldLupId">4316665</identifier> <part> <detail type="volume"> <number>2014:24</number> </detail> <extent unit="pages"> <total>172</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-03-07T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>c896975b-36cc-4445-bf66-4973f55f73ac</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:48+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:48+02:00</recordDateApproved> </recordInfo> </mods>

Patients suffering from inflammatory bowel diseases face an increased risk of intestinal cancer development. Therefore it is important to investigate the role of LTD4 signalling in cancer development and progression. &lt;br/&gt;&lt;br&gt; In this thesis I show that there is an endogenous production of LTD4 in both non-transformed and cancer intestinal epithelial cells leading to a continuous activation of the CysLT1 receptor. The activation of this receptor signals increased proliferation and increased survival. My finding that CysLT1 receptor signalling leads to accumulation of b-catenin in the nuclei and activation of the transcription factor TCF/LEF is in line with the ability of this receptor to promote cell proliferation. However, I also found that CysLT1 receptor activation caused b-catenin to translocate to the mitochondria where it associated with the survival protein Bcl-2. In addition, I observed that LTD4-induced activation of the CysLT1 receptor or overexpression of b-catenin in both non-transformed and cancer intestinal epithelial cells enhanced the activity of the respiratory chain and the production of ROS, as well as increased the transcription of mt-DNA. These effects caused a downstream activation of NF-kB. In conclusion, my results indicate that the pro-inflammatory mediator LTD4 has an important role in tumour development in the intestine by its regulation of cell proliferation and survival.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ca733849-911f-4fe6-9e2f-bb2398ca9b32</url> </location> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>LTD4</topic> <topic>beta-catenin</topic> <topic>colorectal cancer</topic> <topic>CysLT1R</topic> <topic>proliferation</topic> <topic>inflammation</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-77-4</identifier> <identifier type="oldLupId">1258080</identifier> <part> <detail type="volume"> <number>2008:124</number> </detail> <extent unit="pages"> <total>77</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-11-07T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>ca733849-911f-4fe6-9e2f-bb2398ca9b32</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:51+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:51+02:00</recordDateApproved> </recordInfo> </mods>

However, the AR GGC (S/S) genotype and rare AR variant diplotypes were associated with higher testosterone levels during OC use. The GGC (S/S) genotype, but not rare variant AR diplotypes was associated with incident breast cancer, irrespective of the BRCA1/2 mutation status. Since higher testosterone levels may be a risk factor for breast cancer, OC use may increase breast cancer risk among women with the GGC (S/S) genotype or the rare variant AR diplotypes. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper III, post-lactational prolactin levels were determined by breast-feeding duration of the ﬁrst child and not simply by the ﬁrst full-term pregnancy. Since prolactin modiﬁes the risk for breast cancer, adequate counseling in favor of breast-feeding is essential. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper IV, 21.3 % of patients used biologically based complementary and alternative medicine (CAM) preoperatively, and 38.8 % reported the use of CAM during at least one visit. CAM use was associated with certain patient characteristics, such as antidepressant and alcohol use, and with tamoxifen treatment, but not with tumor characteristics or early breast cancer events. CAM use may cause clinically significant drug interactions and it is therefore of clinical interest to identify potential CAM users. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper V, antidepressant use was associated with an over three-fold increased risk and potent CYP2D6 inhibitors with a five-fold increased risk of early breast cancer events among tamoxifen-treated patients with invasive ER positive tumors. Antidepressant use, but not CYP2D6 genotype, was associated with premature tamoxifen cessation. Antidepressant and CYP2D6 inhibitor use, but not CYP2D6 genotype alone or in combination with CYP2D6 inhibitors, predicted five-year disease-free survival in a large prospective cohort of tamoxifen-treated patients.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, lifestyle and genetic polymorphisms that modify hormone levels and treatment response may play an important role in breast cancer.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bröstcancer är den vanligaste cancerformen hos kvinnor i Sverige. Årligen drabbas 7000 kvinnor i Sverige och cirka 1500 kvinnor dör av sin sjukdom. Bröstcancer uppkommer genom ett samspel mellan livsstil, miljö och gener. En kvinna som har en förstagradssläkting (t.ex. syster, mor) med bröstcancer har ungefär dubbelt så stor risk att drabbas av bröstcancer jämfört med en kvinna, som inte har en förstagradsläkting med bröstcancer. Olika typer av mutationer och genetiska varianter, s.k. polymorfier, bidrar till ökad bröstcancerrisk i varierande utsträckning. En mutation i en av bröstcancergenerna, BRCA1 eller BRCA2, innebär upp till 80% livstidsrisk för bröstcancer. BRCA1/2-mutationer är dock ovanliga. Hos de flesta högriskbröstcancerfamiljer med många bröstcancerfall, som även följer ett känt nedärvningsmönster, hittar man trots allt ingen BRCA1 eller BRCA2 mutation. I dessa familjer tror man att bröstcancer beror på samverkan mellan olika vanliga genetiska varianter (polymorfier) och en viss livsstil. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Kända livsstilsfaktorer, som påverkar bröstcancerrisken är t.ex. reproduktiva faktorer: tidig ålder vid första mens och hög ålder vid sista mens ökar risken, medan fullgången graviditet speciellt i ung ålder, samt lång amningstid minskar risken. Användning av p-piller och hormonbehandling mot övergångsbesvär ökar risken för vissa kvinnor. Dessa faktorer är kopplade till hormonnivåer i kroppen och bröstens utveckling. Hormoner, som påverkar bröstets utveckling, har betydelse även för bröstcancer. Flera hormoner har kopplats till bröstcancer och några av dessa är det kvinnliga hormonet östrogen, det manliga hormonet testosteron (ett androgenhormon), och amningshormonet prolaktin. Dessa hormoner binder till sina receptorer (östrogen-, androgen-, och prolaktinreceptorer) för att utöva sina effekter i kroppen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Bröstcancerbehandling bestäms av prognostiska och prediktiva faktorer. Prognosen beskriver bröstcancerns naturalförlopp och är god för de flesta patienterna, ca två tredjedelar av patienterna botas med bara operation. De flesta patienter erhåller dock ytterligare behandling efter operationen, för att döda oupptäckta cancerceller i kroppen. Prediktiva faktorer är egenskaper, som förutsäger möljigheten att en viss typ av tilläggsbehandling ska fungera. Det är dock inte bara tumörens egenskaper, som förutsäger om en viss behandling fungerar, utan även patientens egenskaper. Polymorfier i gener som kodar för enzymer involverade i läkemedelsämnesomsättning kan resultera i ett enzym som inte fungerar normalt. Exempelvis ett icke-fungerande CYP2D6, ett nyckelenzym i aktiveringen av det vanliga bröstcancerläkemedlet tamoxifen, kan resultera i att patienten inte har nytta av sin tamoxifenbehandling. Andra mediciner, såsom naturläkemedel eller antidepressiva, som patienten tar samtidigt med bröstcancerbehandlingen kan minska effekten av bröstcancermedicinen. Många patienter får återfall i sin sjukdom trots att de får och tar sin behandling. Ännu så länge tar man i Sverige inte hänsyn till patientens genetiska egenskaper när man väljer tilläggsbehandling, vilket beror på att kunskap saknas inom området.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I denna avhandling har jag studerat hur samspelet mellan hormoner, genetiska varianter och livsstil påverkar bröstcancerrisken och risken att få återfall i sin sjukdom. Två olika grupper av kvinnor har studerats i denna avhandling. HJH-studien består av 269 unga kvinnor utan bröstcancer som tillhör familjer med hög risk för bröstcancer. BC blodstudien består av bröstcancerpatienter från befolkningen, som kommer till sin första operation i Lunds universitetssjukhus eller Helsingborgs lasarett. Deltagare i båda studierna har lämnat blodprover och fyllt i enkäter med frågor om olika livsstilsfaktorer, såsom användning av p-piller, antal barn, amningstid (HJH-studien) samt användning av antidepressiva och naturläkemedel (BC blod-studien). Blodproverna har använts för analyser av polymorfier i genen som kodar för androgenreceptorn samt i en gen som kodar för CYP2D6 enzymet. HJH-studien användes i arbete I, II och III och BC blodstudien användes i arbete IV och V.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I arbete I och II, undersöktes hur polymorfier i androgenreceptorn var kopplade till androgenhormonnivåer och hur nivåerna påverkades av p-pilleranvändning. Hos de flesta kvinnor som åt p-piller, var androgenhormonnivåerna lägre jämfört med kvinnor som inte åt p-piller. Två normalvarianter i androgenreceptorgenen var kopplade till högre testosteronnivåer hos kvinnor som åt p-piller. En av dessa var kopplad till högre bröstcancerrisk.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I arbete III, undersöktes hur amningslängd och den självrapporterade mjölkproduktionen var kopplade till prolaktinnivåer. Ju längre en kvinna hade ammat sitt första barn, desto lägre var prolaktinnivåerna. Kvinnor som uppfattade sin mjölkproduktion som otillräcklig hade högre prolaktinnivåer. Amning av ytterligare barn påverkade inte prolaktinnivåerna. Eftersom höga prolaktinnivåer ökar risken för bröstcancer, bör alla kvinnor uppmuntras att amma så länge som möjligt, så länge det inte finns någon medicinsk anledning att inte amma.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I arbete IV undersöktes hur vanligt användning av naturläkemedel var hos bröstcancerpatienter och om den var associerad med kortare sjukdomsfri överlevnad. Naturläkemedelsanvänding var vanligare bland bröstcancerpatienter än bland friska kvinnor i Sverige (rapporterad i en annan studie) och var kopplad till användning av alkohol och antidepressiva samt normalt BMI och rökfrihet. Naturläkemedelsanvändning var inte kopplat till kortare eller längre sjukdomsfri överlevnad. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I arbete V undersöktes dels hur polymorfier i genen som kodar för CYP2D6 enzymet påverkar behandlingsutfallet med tamoxifen, och hur användning av läkemedel som hämmar funktionen av CYP2D6 enzym påverkar behandlingsutfallet med tamoxifen. Antidepressivanvändning var kopplad till större risk för återfall i bröstcancer eller ny bröstcancer hos tamoxifenbehandlade patienter. Polymorfier i CYP2D6-genen var inte kopplade till sämre behandlingsutfall hos tamoxifenbehandlade patienter.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis identifierar avhandlingen genetiska och livsstilsfaktorer som påverkar hormonnivåer hos unga kvinnor från högriskbröstcancerfamiljer och som kan ha betydelse för risken att insjukna i bröstcancer. Avhandlingen identifierar även livsstilsfaktorer, som kan vara kopplade till sämre behandlingsutfall hos bröstcancerpatienter. Dessa fynd, om de bekräftas i flera studier, kan i framtiden bidra till identifiering av kvinnor som har högre risk för bröstcancer vid p-pilleranvändning. Dessa fynd kan även bidra till att kunna ge bättre råd angående livsstilsfaktorer hos bröstcancerpatienter samt ge bättre underlag för terapival.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/eb8d6056-f86c-46f3-9155-36bd29d14008</url> </location> </relatedItem> <originInfo> <publisher>Department of Oncology, Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Breast cancer</topic> <topic>BRCA1</topic> <topic>BRCA2</topic> <topic>androgen receptor</topic> <topic>CAG</topic> <topic>GGC</topic> <topic>polymorphism</topic> <topic>htSNP</topic> <topic>oral contraceptives</topic> <topic>testosterone</topic> <topic>breast-feeding</topic> <topic>prolactin</topic> <topic>premenopausal women</topic> <topic>CYP2D</topic> <topic>complementary and alternative medicin</topic> <topic>antidepressants</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-32-0</identifier> <identifier type="oldLupId">1578979</identifier> <part> <detail type="volume"> <number>2010:18</number> </detail> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-04-09T13:00:00+02:00</dateOther> <note type="additionalInfo">Financial support from: BRO (Bröstcancerföreningarnas riksorganisation), the Mrs. Berta Kamprad&apos;s Foundation, the Gunnar Nilsson Foundation, the South Swedish Health Care Region (Region Skåne, ALF), the Lund Hospital Fund, the Swedish Cancer Society, and the Crafoord Foundation.</note> <recordInfo> <recordIdentifier>eb8d6056-f86c-46f3-9155-36bd29d14008</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:16:55+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:16:55+02:00</recordDateApproved> </recordInfo> </mods>

Side effects related to therapy are long lasting and adversely affects quality of life. The incidence of oropharyngeal cancer is increasing and patients commonly present an advanced tumour stage with neck metastases at the time of diagnosis. The treatment protocol previously comprised radical (chemo)radiotherapy and surgery i.e., neck dissection. However, persistent tumour cells after (chemo)radiotherapy are found in only 20-30% of the neck specimens and a systemic neck dissection have therefore been questioned. &lt;br/&gt;&lt;br&gt; The general aim of the present thesis was to explore if positron emission tomography (PET) could be used for radiotherapy response evaluation and adequately determine the need for further therapeutic interventions in patients with HNSCC treated with curative intent. The overall clinical goal with the thesis was to reduce the treatment related morbidity by avoiding unnecessary neck dissection without risking an increase in failures.&lt;br/&gt;&lt;br&gt; In studies I and III we evaluated the performance of PET as a tool for assessment of therapy response and the consequences of omitting neck dissections in patients with a complete metabolic response after treatment. Study II focused on therapy response evaluation of the primary site. Lastly, study IV evaluated three different methods for interpreting PET scans in head and neck cancer patients.&lt;br/&gt;&lt;br&gt; In conclusion, neither nodal control nor survival is compromised by omitting neck dissection in patients with a complete metabolic response after therapy. A physical examination, preferably supported with a PET scan, is feasible and sufficient for an evaluation of the primary site response. Qualitative interpretation with visual inspection of PET scans is a satisfactory method to assess tumour metabolism and the use of a 5-point Likert scale is a promising tool to reduce the number of scans judged as equivocal to a minimum.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; I gruppen huvudhalscancer ingår tumörer i övre luftvägar och svalg. Riskfaktorer för huvudhalscancer är rökning och alkoholöverkonsumtion. Under de senaste 20-30 åren har det skett en påtaglig ökning av insjuknandet, 4-5% per år, i det som kallas orofaryngeal cancer. Orofaryngeal cancer utgår från mellansvalget; mandlar, tungbas och mjuka gommen. Ökningen sammanfaller med att man ser en uppgång i tumörer som anses associerade med humant papillomvirus och det är ett något yngre patientklientel, utan de ovan nämnda traditionella riskfaktorerna, som insjuknar.&lt;br/&gt;&lt;br&gt; Medianåldern för insjuknande är drygt 60 år. De flesta patienterna har spridning av sin tumör till lymfknutor på halsen vid tidpunkten för diagnos.&lt;br/&gt;&lt;br&gt; Strålbehandling, ibland med samtidig cellgiftsbehandling, ges till både modertumör och sjuka lymfknutor hos patienter där man syftar till bot. Tidigare behandlingsprotokoll inkluderar en utvärdering av strålbehandlingsresultatet. Patienten blir då sövd och man undersöker svalget och tar vävnadsprov. Om det inte finns någon kvarvarande tumör i svalget opereras lymfknutorna på halsen bort. Skulle det finnas tumör kvar i lymfknutorna så har patienten i och med operationen fått sin tilläggsbehandling.&lt;br/&gt;&lt;br&gt; Behandlingen är förknippad med såväl övergående akuta som sena, livslånga biverkningar. Sena biverkningar är sväljningsproblem och muntorrhet av varierande grad samt lokal påverkan på blodcirkulationen vilket kan ge läkningssvårigheter vid exempelvis tandingrepp och kirurgi i det strålade området. Nack/skulderproblem med inskränkt rörlighet och smärta är vanligt efter halsoperationen pga nervpåverkan, kraftig ärrbildning och stram vävnad. Kombinationen av strålbehandling och operation förvärrar problematiken och påverkar livskvalitén negativt.&lt;br/&gt;&lt;br&gt; Efter modern strålbehandling har man sett att i endast 20-30% av fallen finns det kvarvarande tumörceller i lymfknutorna på halsen och således kan man anta att upp till 80% av patienterna opereras utan någon vinst avseende sjukdomskontroll eller överlevnad. De får däremot biverkningar efter ingreppet.&lt;br/&gt;&lt;br&gt; Studierna i den här avhandlingen har primärt fokuserat på utvärdering av strålbehandlingseffekten och om vi på ett säkert sätt kan avstå från halsoperation i de fall där strålbehandlingen har haft fullgod effekt. &lt;br/&gt;&lt;br&gt; Hur ska man då utvärdera strålbehandlingseffekten? Vi har använt oss av en nuklearmedicinsk metod, positron emissions tomografi (PET). Med PET utnyttjar man det faktum att cancerceller har ett högt sockerbehov, högre än omkringliggande normala celler. Inför en PET-undersökning ges en injektion av en radioaktivt märkt sockeranalog till patienten. Cancercellerna tar upp förhållandevis mycket av det radioaktiva sockret och det kan detekteras av en PET-kamera. På PET-bilden ser man tumörer med högt upptag som starkt lysande områden vilket talar för hög aktivitet i tumören. Genom att jämföra PET-undersökningar gjorda före och efter strålbehandling kan man se om tumörområdena har ”släckts”.&lt;br/&gt;&lt;br&gt; I studierna har vi sett att PET är en bra metod för att detektera och utesluta kvarvarande tumörceller i halslymfknutor efter strålbehandling. Vi kan på ett säkert sätt avstå från halsoperation i de fall där tumörerna är ”släckta” efter strålbehandlingen. Det tycks inte påverka risken för att få återfall av tumör i lymfknutorna på halsen och det tycks inte heller påverka överlevnaden på ett negativt sätt jämfört med om man rutinmässigt utför en halsoperation efter strålbehandling. Tidpunkten för utvärdering av strålbehandlingen med PET kan diskuteras och vi anser att man får ett säkrare resultat om man gör den närmare 12 jämfört med sex veckor efter strålbehandling. &lt;br/&gt;&lt;br&gt; Från våra resultat kan man också konstatera att modellen för utvärdering av eventuellt kvarvarande modertumör, sövning av patienten och vävnadsprov, är överdriven. Det är mycket ovanligt med en kvarvarande modertumör efter strålbehandlingen och en vanlig klinisk undersökning, eventuellt ihop med PET-undersökning är fullt tillräckligt. Vid misstanke om kvarvarande tumör kan ytterligare undersökningar genomföras. &lt;br/&gt;&lt;br&gt; Man kan använda olika metoder för att tolka och beskriva PET-bilder. Att göra en visuell bedömning är i de flesta fall fullt tillräckligt. Vi har dock konstaterat att PET-bilder med tumörer som är bedömda som ”tveksamt släckta” kan omvärderas med hjälp av en 5-punkts skala. Man tycks med 5-punktsskalan kunna omklassificera bilderna som ”släckta” eller ”fortsatt förhöjd aktivitet” och således få ett säkrare svar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f3d1202e-0755-4838-a7b3-d58b8cde0efa</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Dissertation_J_SjAPvall__without_paper_IV.pdf">https://portal.research.lu.se/files/3276714/7767015.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4311423</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Otorhinolaryngology, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Head and neck cancer</topic> <topic>positron emission tomography</topic> <topic>radiotherapy</topic> <topic>treatment evaluation</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-161-3</identifier> <identifier type="oldLupId">7767012</identifier> <part> <detail type="volume"> <number>2015:82</number> </detail> <extent unit="pages"> <total>93</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-09-25T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f3d1202e-0755-4838-a7b3-d58b8cde0efa</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:17:01+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:17:01+02:00</recordDateApproved> </recordInfo> </mods>

However, the disease has only been a clearly defined entity for 13 years. Due to its recent recognition, DLB is still not as extensively studied as are other major dementia disorders such as Alzheimer’s disease (AD), vascular dementia, and fronto-temporal dementia.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In summary, this thesis demonstrates important differences between AD and DLB. Paper I and II focus on the ultimate consequences of the disease, including resource consumption and impact on quality of life, and demonstrate much more severe consequences of DLB. Paper III and IV focus on diagnosis and prediction of disease progression through CSF analysis, and demonstrate a robust increase of CSF Ca and Mg in DLB but not in AD. Furthermore, CSF t-tau, a marker of AD and neurodegeneration, is demonstrated to increase mortality in DLB, but not in AD. These DLB specific CSF findings give us further understanding of the factors that may trigger the disease and determine disease course. Furthermore, CSF Mg and Ca may be a valuable tool in making a DLB diagnosis, especially when the considered differential diagnosis is AD.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b83b3e8e-c9ee-407a-b633-cf0adc1c5414</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Fardig_Avhandling_Bostrom_090811.pdf">https://portal.research.lu.se/files/3277378/1485549.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3275648</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Clinical Memory Research Unit, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Lewy body disease</topic> <topic>Alzheimers disease</topic> <topic>Dementia</topic> <topic>Dementia with Lewy bodies</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-57-8</identifier> <identifier type="oldLupId">1485546</identifier> <part> <detail type="volume"> <number>2009:69</number> </detail> <extent unit="pages"> <total>41</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-09-12T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>b83b3e8e-c9ee-407a-b633-cf0adc1c5414</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:17:07+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:17:07+02:00</recordDateApproved> </recordInfo> </mods>

A second aim was to explore a preventive intervention in a pilot study using case managers to older people with functional dependency and repeated healthcare contacts.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Study I was qualitative and comprised 14 people (mean age 81) who were interviewed about their experiences of the&lt;br/&gt;&lt;br&gt; healthcare and social services delivered to them. The results were analysed using content analysis. A cross-sectional, comparative design was used in studies II and III, which comprised 362 people who received a decision about the provision of municipal care or/and services during 2002-2003 and the participants were drawn from the Swedish National Study of Aging and Care (SNAC) and the county council register of healthcare consumption and costs. Study IV was a pilot trial with an experimental design and comprised 35 people who were consecutively and randomly assigned to either an intervention (n=19)&lt;br/&gt;&lt;br&gt; or a control (n=16) group. Two nurses worked as case managers and carried out the intervention, which had four dimensions. Data were collected at baseline and after the intervention had been in place for about three months.&lt;br/&gt;&lt;br&gt; Study I showed that the experience of receiving healthcare and/or social services in old age could be interpreted&lt;br/&gt;&lt;br&gt; according to the overall theme “Having power or being powerless”, divided into three main categories: Autonomous or without control in relation to the healthcare and/or social service system; Confirmed or violated in relation to caregivers and Paradoxes in healthcare and social services. The results from Study II showed that about 50% of the acute hospital stays occurred within&lt;br/&gt;&lt;br&gt; the five months prior to receiving municipal care. The men (n= 115, mean age 80.8) had significantly more bed days in&lt;br/&gt;&lt;br&gt; hospital, more diagnoses and contacts with other staff groups besides physicians in outpatient care compared to the women (n=247, mean age 83.8). The results from study III showed that 13% of the sample had overall higher healthcare costs throughout the two years of observation. A majority (58% for the women and 54% for the men) of the costs for acute inpatient care occurred within five months prior to municipal care. The results from Study IV showed no differences between groups at baseline. Those included reported low life satisfaction, low perceived health and were also at risk of suffering from depression. The Life Satisfaction Index, Geriatric Depression Scale-20 and the ADL staircase had satisfactory internal consistency.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Healthcare staff must be aware of the risk that older people loose control over their life situation when receiving healthcare and/or social services from various agencies. Preventive interventions and a more empowering approach are seemingly needed. This requires continuity and accessibility on an individual and organisational level. Early detection through a systematic clinical assessment, a more proactive and integrated care and applying preventive interventions to people in a&lt;br/&gt;&lt;br&gt; transitional stage of becoming increasingly dependent on continuous care and services seems urgent to prevent escalating acute hospital admissions and thereby costs. The intervention had a feasible design. The sampling procedure led to similar groups and the measures were reliable to use. Both groups had a low life satisfaction, a low self reported health and were at risk of having a depression and could benefit from preventive interventions. No effects were found on self perceived health and depressed mood after three months. This might be due to the follow up time being too short. Further investigations about the content of the interventions are needed in the future.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4097866f-e0e0-46da-b36a-c5f19754745d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa.pdf">https://portal.research.lu.se/files/3277810/1041137.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">578657</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Long Term Care</topic> <topic>Primary Health Care</topic> <topic>Outpatients</topic> <topic>Registries</topic> <topic>Pilot Studies</topic> <topic>Content Analysis</topic> <topic>Case Management</topic> <topic>Hospital</topic> <topic>Emergency Services</topic> <topic>Frail Elderly</topic> <topic>Hospitalizations</topic> <topic>Intervention Studies</topic> <topic>Health Care Costs</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-80-3</identifier> <identifier type="oldLupId">1040773</identifier> <part> <detail type="volume"> <number>2008:27</number> </detail> <extent unit="pages"> <total>206</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-03-27T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>4097866f-e0e0-46da-b36a-c5f19754745d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:17:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:05:11Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:17:11+02:00</recordDateApproved> </recordInfo> </mods>

Proteins from galectin family were found to contribute to disease pathophysiology. Therefore, there is an intensive interest in understanding different galectin functions. The aim of this thesis was to pin-point specific galectin-3 roles in differently activated macrophages. Additional aim was to understand the mechanism and consequences of galectin-3 ligand binding.&lt;br/&gt;&lt;br&gt; In the first paper galectin-3 endocytosis was studied in a system of differently activated macrophages. We found that inflammatory, M1, and alternatively activated, M2, macrophages have a large capacity to internalize externally added galectin-3, besides expressing and secreting galectin-3. Additionally, we found that galectin-3 does not require the functional carbohydrate recognition domain (CRD) for its endocytosis. &lt;br/&gt;&lt;br&gt; In the second paper we used M2 macrophages to study how galectin-1 directs the endocytosis of hemoglobin-haptoglobin complex. Our results indicated that galectin-1 bound fraction of the complex takes a recycling intracellular route instead of the pathway for degradation. &lt;br/&gt;&lt;br&gt; The third paper shows how certain complex carbohydrate ligands can induce galectin-3 self-association that involves CRD to CRD binding. This “type-C” self-association engages more galectin-3 molecules than there are available glycan ligands and can explain certain biological events that require fast galectin-3 mobilization. &lt;br/&gt;&lt;br&gt; In the fourth paper we tested the inhibitory potential of a few plant products for several galectins. We found that their activity was very weak, hence the search for more potent anti-galectin, perhaps also anti-inflammatory remedies continues.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Uncoded languages&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Kronična upala je u podlozi mnogih bolesti modernog čovjeka kao što su djiabetes, astma, ateroskleroza itd. Upalu predvode različiti tkivni makrofagi. Proteini iz porodice galektina, proizvedeni u makrofagima, dodatno pridonose razvoju bolesti, stoga je od velikog interesa odgonetnuti različite funkcije galektina. Ovaj rad nastoji identificirati specifične uloge galektina-3 u različito aktiviranim makrofagima te razumjeti mehanizam i posljedice vezanja galektina-3 za ligand. &lt;br/&gt;&lt;br&gt; U prvom radu proučavali smo endocitozu galektina-3 u različito aktiviranim makrofagima. Vidjeli smo da upalni, M1, i alternativno aktivirani, M2, makrofagi proizvode i izlučuju galektin-3 te također mogu endocitozom unositi velike količine galektina-3 dodanog iz vana. Domena koja prepoznaje ugljikohidrat galektina-3 (CRD) nije bila neophodna za endocitozu. &lt;br/&gt;&lt;br&gt; Drugi rad proučava mehanizam kojim galektin-1 usmjerava endocitozu hemoglobinsko-haptoglobinskog kompleksa u M2 makrofagima. Rezultati ukazuju da se galektin-1 dijelom veže na kompleks te ga usmjerva unutar stanice, zaobilazeći put razgradnje, možda u korist recikliranja. &lt;br/&gt;&lt;br&gt; Treći rad bavi se samozdruživanjem galektina-3 koje se ostvaruje kroz međusobnu interkaciju CRD galektina-3. Takav tip samozdruživanja (tip-C) može inicirati samo određeni tip složenog ugljikohidratnog liganda. U vezanje je uključeno više molekula galektina-3 nego što je rasploživog liganda, stoga proces podržava brzu mobilizaciju galktina-3.&lt;br/&gt;&lt;br&gt; U zadnjem radu testirali smo nekolicinu biljnih prerađevina u potrazi za galektinskim inhibitorima. Pokazali smo da određeni biljni produkti vrlo slabo djeluju na nekoliko testiranih galektina. Djelotvnorni galektinski inhibitori su i potencijalni protuupalni lijelovi te bi njihov pronalazak i razvoj mogao biti od velike koristi.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6c52b959-b2d8-4810-8c7b-ece15b50d6f9</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Adriana_Lepur_el_publication.pdf">https://portal.research.lu.se/files/3278791/3048544.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1426078</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>galectin-3</topic> <topic>galectin-1</topic> <topic>M1 macrophage</topic> <topic>M2 macrophage</topic> <topic>self-association</topic> <topic>fluorescence anisotropy</topic> <topic>citrus pectin</topic> <topic>galactomannane</topic> </subject> <subject authority="lup"> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-31-9</identifier> <identifier type="oldLupId">3048521</identifier> <part> <detail type="volume"> <number>2012:68</number> </detail> <extent unit="pages"> <total>71</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-10-05T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>6c52b959-b2d8-4810-8c7b-ece15b50d6f9</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:17:20+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:17:20+02:00</recordDateApproved> </recordInfo> </mods>

In many European clinical settings, inappropriate nursing practice of bedside monitoring and management has recently been addressed as impending to in-hospital patient safety. Vital parameters have for two decades been known to deviate in individual patients hours ahead of serious adverse events, but this knowledge has not yet been generally rooted among nursing and medical in-hospital staff, contributing to misinterpretation of individual vital signs and inadequate bedside action being taken. Accordingly, this knowledge of the predictable value of deviations in bedside vital parameters has not until recently been reflected in general ward patient monitoring practice. &lt;br/&gt;&lt;br&gt; A clinical multi-component intervention comprising mandatory nursing bedside monitoring, based on structured regular in-hospital use and recording of modified early warning scores in in-hospital patients, was implemented by structured interprofessional teaching, training and promotion in a large medical and surgical study setting at an urban Scandinavian university hospital. This thesis has been based on four non-randomized pre- and postinterventional studies on bedside practice in this context (I-IV). Outcome measures of particular interest were associations between early deviation in various vital parameters and later severe deterioration (IV), and potential effects of the study intervention on unexpected death (III). &lt;br/&gt;&lt;br&gt; Before implementation of the study intervention, nursing monitoring practice was found to be influenced mainly by individual levels of professionalism, characterized by knowledge, reflection, and interprofessional collaboration (I).&lt;br/&gt;&lt;br&gt; After this implementation, the three most common bedside vital parameters were found to be recorded more frequently (II), and the unexpected in-hospital patient mortality in the study setting to be significantly lower (III), than before. Moreover, the medical emergency team was called in three times more often (III). Three quarters of the patients were rescored within the time limits of eight and four hours stated in the algorithm of bedside management (II). Sudden tachycardia or tachypnea in slightly deteriorated, particularly older, in-hospital patients was found to be significantly associated with later severe clinical deterioration (IV).</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Danish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Summary in Danish &lt;br/&gt;&lt;br&gt; Patientsikkerhed på hospital – forebyggelse af uventede dødsfald via systematisk anvendelse af et Early Warning Score system&lt;br/&gt;&lt;br&gt; På hospitaler i den vestlige del af verden sker det, på trods af store indsatser for at øge patientsikkerheden, at indlagte patienters tilstand forværres alvorligt, og at nogle af disse patienter i værste tilfælde dør, som konsekvens af utilstrækkelig overvågning og uoptimal håndtering af situationen fra hospitalspersonalets side. I de sidste tyve år har man haft kendskab til, at patienter, der dør uventet på hospital, frembyder afvigende vitale parametre (puls, vejrtrækningsfrekvens, blodtryk og temperatur) i op til 48 timer inden det uventede dødsfald.&lt;br/&gt;&lt;br&gt; Studier fra andre europæiske lande har dog vist, at noget af problemet med uventede dødsfald på hospital skyldes, at en stor del af det kliniske personale ikke er fortrolig med viden om betydningen af afvigende vitale parametre, og at de er usikre på, hvordan de skal tolke og agere overfor afvigende vitale parametre. Derudover har der, indtil for nylig, fra hospitalsorganisationers side, ikke været fokuseret på at introducere en øget observationspraksis inklusiv øget kendskab til håndtering af ustabile patienter.&lt;br/&gt;&lt;br&gt; Formålet med dette studie var at undersøge patientsikkerheden på almen medicinsk og kirurgisk afdeling på et dansk hospital, set i relation til sygeplejerskers observationspraksis af vitale parametre og det tværfaglige samarbejde vedrørende ustabile patienter. Undersøgelsen blev påbegyndt i 2009, hvor fire måneder i foråret udgjorde før-interventions perioden, og fire måneder i efteråret 2010 og i foråret 2011 udgjorde de to efter-interventionsperioder.&lt;br/&gt;&lt;br&gt; Indledningsvist undersøgte vi via observationer og interview den aktuelle observationspraksis. Det videre studie blev designet som et interventionsstudie med henblik på at undersøge, om en obligatorisk, systematisk og tværfaglig anvendelse af et observations- og vurderingsredskab, et såkaldt Early Warning Score system, kan opspore patienter i risiko for at blive akut kritisk syge, og om dette i kombination med et nyt dokumentationsredskab og en handlingsalgoritme kan bidrage til hurtigere iværksættelse af korrekt pleje og behandling.&lt;br/&gt;&lt;br&gt; Det overordnede formål var at undersøge interventionens effekt på antallet af uventede dødsfald, hjertestop eller uventet indlæggelse på intensiv afdeling hos patienter indlagte på almen kirurgisk og medicinsk afdeling. Desuden var formålet at undersøge i hvor høj grad interventionen var blevet fulgt, og hvordan implementeringsprocessen blev oplevet af personalet tæt på klinisk praksis. &lt;br/&gt;&lt;br&gt; Sluttelig ønskede vi at bestemme forbindelsen mellem tidligt opståede, lettere afvigende vitale parametre, og senere alvorlig forværring.&lt;br/&gt;&lt;br&gt; Resultaterne af den indledende observations- og interview undersøgelse viste, at der hos sygeplejersker fandtes et meget varierende niveau af professionalisme; et begreb, der indeholder karakteristika som: viden, evnen til at reflektere, autonomi men også arbejdsmiljøet og det tværfaglige samarbejde er indeholdt i begrebet professionalisme. Den enkelte sygeplejerskes grad ad professionalisme har indflydelse på hendes observationspraksis, og dette kan få betydning for patientsikkerheden. &lt;br/&gt;&lt;br&gt; Vejledt af litteraturen og resultaterne fra observations- og interviewstudiet blev der foretaget en række forskellige implementeringstiltag. Klinikere fra projekt afdelingen evaluerede, at det meningsgivende i interventionen og det store faglige fokus i projektet havde været meget motiverende for deres deltagelse og havde styrket en vellykket implementering af den kliniske intervention. Både ledelse og medarbejdere var aktivt inddraget i implementeringsfasen.&lt;br/&gt;&lt;br&gt; I de afdelinger der deltog i studiet, ændrede den daglige observationspraksis sig således, at tiden mellem individuelle målinger af puls, blodtryk og temperatur blev mindsket betydeligt. Derudover opnåede 75% af alle patienter af få repeteret måling af deres vitale parametre inden for den tidsramme på 8 og 4 timer som handlingsalgoritmen foreskrev. Alt i alt blev der målt tre gange så mange sæt vitale parametre i hver af de to efter-perioder som i før perioden. Hospitalets Mobile Akut team blev tilkaldt 3 gange oftere i perioden efter i forhold til i perioden før interventionen. &lt;br/&gt;&lt;br&gt; Forekomsten af uventede dødsfald faldt markant, hvis man sammenligner før-perioden med den sidste efter-periode. Men allerede i den første efter-periode var der et tydeligt, men ikke statistisk signifikant fald. &lt;br/&gt;&lt;br&gt; I den sidste undersøgelse fandt vi, at små ændringer i puls og vejrtrækningsfrekvens er forbundet med senere alvorlig forværring, Stigende alder er ligeledes forbundet med senere alvorlig forværring. Desuden forværredes 25%, af de, der havde fået målt tidlige og små afvigelser, senere alvorligt, med øget risiko for død til følge. Ca. halvdelen forværredes allerede inden for de første 48 timer.&lt;br/&gt;&lt;br&gt; Konklusionen på projektet er, at det er muligt at bidrage til nedbringelse af antallet af uventede dødsfald på hospital via en daglig, tværfaglig og struktureret anvendelse af et early warning score system og et understøttende handlings og dokumentationsredskab.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8f85afb5-0ef6-4693-a25a-6fec7537f2a2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_Gitte_Bunkenborg_master_260314.pdf">https://portal.research.lu.se/files/3278810/4394324.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1391838</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Anaesthesiology and Intensive Care</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Patient safety</topic> <topic>Adverse event</topic> <topic>Vital parameters</topic> <topic>Deterioration</topic> <topic>Early warning score</topic> <topic>Mortality rate</topic> <topic>Unexpected death</topic> <topic>Clinical intervention</topic> <topic>Adherence</topic> <topic>Implementation</topic> <topic>association</topic> </subject> <subject authority="lup"> <topic>Anesthesiology and Intensive Care</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-78-6</identifier> <identifier type="oldLupId">4391307</identifier> <part> <detail type="volume"> <number>2014:52</number> </detail> <extent unit="pages"> <total>156</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-04-25T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>8f85afb5-0ef6-4693-a25a-6fec7537f2a2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:17:20+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:17:20+02:00</recordDateApproved> </recordInfo> </mods>

One crucial aspect concerns the degree to which the built environment is accessible for all people including those with reduced functional capacity. The overarching objective of this thesis was to explore and further develop methodology for accessibility assessments based on the notion of person-environment fit. Type profiles that represent groups characterized by their combinations of functional limitations were explored as an approach to analyze accessibility problems at the group level. To support societal planning and decision procedures, basic simulated accessibility analyses were conducted as a method to identify different sets of housing improvement priorities that are applicable for groups with different functional capacity. Sixty-one core environmental barriers in terms of accessibility problem detection were identified. This represented a preliminary version of an accessibility screening tool, which can be efficient for research and policy interventions focusing on accessibility. Based on a conceptual analysis, techniques for statistically analyzing the variation of agreement data were explored. This approach can identify the most influential sources of disagreement. Finally, a typology of person-environment fit constellations was constructed, which will thereby facilitate an extension of the methodology for accessibility assessments that are applicable in different environmental arenas. The results of this thesis have implications for further research related to the development of tools and methods that can ultimately support societal efforts in achieving a built environment that is accessible for all citizens, regardless of functional capacity.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4e79bbc3-5e0c-41a4-9af3-27fe00bac0b2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="B_Slaug_Thesis__2012-05-10.pdf">https://portal.research.lu.se/files/3278934/2539386.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1453735</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Accessibility</topic> <topic>Aged</topic> <topic>Disabled persons</topic> <topic>Environmental barrier</topic> <topic>Environment design</topic> <topic>Functional limitation</topic> <topic>Interrater agreement</topic> <topic>Public health</topic> <topic>Supportive environments</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-03-6</identifier> <identifier type="oldLupId">2539367</identifier> <part> <detail type="volume"> <number>2012:41</number> </detail> <extent unit="pages"> <total>188</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-06-01T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>4e79bbc3-5e0c-41a4-9af3-27fe00bac0b2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:17:23+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:17:23+02:00</recordDateApproved> </recordInfo> </mods>

The currently used control systems and languages for control were developed with a more static production in mind. More flexible languages and tools are needed to get a more flexible production. The flexible graphical programming language Grafchart, based on the IEC 61131-3 standard language Sequential Function Charts (SFC), is considered with the focus to make it usable in an industrial context.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Modern compiler techniques are evaluated for JGrafchart, a Grafchart implementation, with focus on extensible automation language implementations.

Molecular mechanisms for tumour progression are currently being explored in scientific settings, suggesting parallel evolution of tumour cells at primary and metastatic locations. The molecular profiles could be altered affecting individual patient’s treatment and prognosis. In the work presented in this thesis the main focus was on evaluating tumour tissue and disseminated cells from different metastatic locations, to analyse the distribution of biomarkers and relate them to the prognosis for individual patients.&lt;br/&gt;&lt;br&gt; A relationship has been recognised between the presence of disseminated tumour cells (DTCs) in bone marrow and poor prognosis in several studies, but the method of DTC detection has yet to be validated. It is at present not known whether DTCs will grow into overt metastases or which biologic events are involved in the metastatic process. In paper I, Bone marrow biopsies were performed at the time of primary surgery and the presence of DTCs analysed. After 5 years of follow-up, all reports of events were abstracted from the patient’s records and a database was constructed for all the patients included in the study. The presence of DTCs in the bone marrow was found not to have any prognostic influence and it was concluded that it is too early for clinical implementation due to discrepancies in methods between studies, and the invasive nature of bone marrow biopsies.&lt;br/&gt;&lt;br&gt; Oestrogen receptors (ER), progesterone receptors (PR), Ki67 and human epidermal growth factor receptor 2 (HER2) were compared in primary breast cancer tumours and the synchronous lymph node metastases (Papers II and IV) and primary tumours and relapses (Paper IV). High concordance was found between primary tumours and lymph node metastases regarding separate biomarker expression in both papers, but a significant skewness was observed when biomarkers in primary tumours were compared to those in relapses. Classification into molecular subtype according to the St Gallen guidelines (Papers III and IV) identified a shift in molecular subtype in individual patients that affected prognosis, suggesting that the molecular subtype of the lymph node metastasis has a prognostic influence. Prognostic information for the individual patient can thus be obtained by analysing biomarker expression in synchronous metastatic lymph nodes. The findings presented in Paper IV support the recommendation that biomarker analysis is performed in loco-regional and distant relapses.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bröstcancer är den vanligaste cancerdiagnosen hos svenska kvinnor, ca 8000 tumörer diagnosticeras årligen. Vid rekommendation om behandling till patienter med nyupptäckt bröstcancer utgår man från ett antal prognostiska (risk för återfall och död utan behandling) och prediktiva (risk för återfall och död med specifik behandling) faktorer. Ålder, tumörstorlek, cancercellens grad av avvikelse från den normala bröstcellen, och spridning till lokala lymfkörtlar utgör tillsammans med mikroskopisk analys av tumörens enskilda uttryck av biomarkörer (östrogen- och progesteronreceptorer, proliferationsmarkör Ki67 och tillväxtproteinet HER2) sådana faktorer. Sjukdomen är förknippad med god prognos, den totala femårsöverlevnaden är ca 90 %, men med kunskap om cancercellens utveckling och vilka molekylära processer som föregår återfall i sjukdomen, kan identifiering av patienter vilka har nytta av behandling ytterliggare förbättras. Idag får många patienter kanske överbehandling, de skulle inte komma att drabbas av återfall i sjukdomen, medan andra får återfall trots behandling. Vi undersökte om förekomsten av enstaka tumörceller i benmärg hos patienter med nydiagnosticerad bröstcancer kunde skilja ut patienter med sämre prognos än de som inte hade tumörceller i benmärgen. Den tidiga spridningen av tumörceller går inte att se genom någon idag känd diagnostisk metod, t ex på röntgenbilder. Det har föreslagits att dessa spridda tumörceller vilar i benmärg, som skulle fungera som en reservoar. Genom analys av benmärgsbiopsi för identifiering av förmodade tumörceller, har man i studier funnit att förekomst av dessa celler identifierar patienter mer benägna att få återfall. Vår undersökning av ca 500 patienter påvisade ingen prognostisk information av förekomsten av tumörceller i benmärg hos patienter som genomgick benmärgsbiopsi i samband med operation av bröstcancer. Metoden för provtagning kan vara smärtsam för patienterna, förenad med vissa risker och analysmetoden för identifiering av tumörceller har inte helt säkert fastställts. Utifrån detta kan man sammanfatta att det är för tidigt att använda benmärgsbiopsi för prognostisk information i kliniskt arbete. Pågående studier där man letar efter cirkulerande tumörceller i blod och relaterar till prognos och behandlingseffekt kan sannolikt bidra till mer kunskap om dessa enstaka spridda tumörcellers betydelse, till mindre obehag för patienterna då det är ett blodprov som analyseras.&lt;br/&gt;&lt;br&gt; Analys av genuttryck i bröstcancerceller har visat att klassificering av tumörer utifrån en kombination av biomarköruttryck kan bidra med prognostisk information utöver den man idag erhåller från analys av dessa biomarkörer vid separat analys. Nyligen rekommenderade en högt ansedd expertgrupp vilka biomarkörer i kombination som hade bäst vetenskapligt stöd, denna följer vi i de i avhandlingen ingående studierna - St Gallens molekylära subtyp klassificering.&lt;br/&gt;&lt;br&gt; En av de enskilt starkaste prognostiska faktorerna är förekomst av spridning av tumörceller till armhålans lymfkörtlar, finns det tumörväxt (lymfkörtelmetastaser) i dessa vid den primära kirurgin opereras lymfkörtlarna i armhålan bort samtidigt med brösttumören. Sjukdomen ses då fortfarande som botad men med högre risk för återfall och död i bröstcancersjukdomen. Vi analyserade uttryck av biomarkörer i tumörceller från primärtumörer och tumörceller från samtidiga lymfkörtelmetastaser hos samma patient med primär bröstcancer, i syfte att identifiera eventuella skillnader och relatera detta till prognos. Vi fann hög samstämmighet vid analys av enskilda biomarkörer mellan primärtumör och lymfkörtelmetastas men vid analys av en kombination av biomarkörer enligt St Gallens molekylära subtyp klassificering, visade sig enskilda patienter bli klassificerade till olika molekylära subtyper i primärtumör och lymfkörtelmetastas. Resultaten av bytet av molekylär subtyp tyder på att uttrycket i lymfkörteln, och inte i primärtumören, kan bära på prognostisk information. Rekommendation om behandling baserat på lymfkörtelns molekylära subtyp klassificering skulle innebära tillägg av kemoterapi utöver endokrin behandling. Vi identifierade också en grupp av patienter som det gick mycket bra för, som kanske inte skulle ha nytta av tilläggsbehandling, trots förekomst av riskfaktorer, vars tumörer diagnosticerats inom ramen för hälsokontroller med mammografi (screening), där den molekylära subtypen i lymfkörtelmetastasen gav prognostisk information. Det är få patienter och resultaten behöver bekräftas i större studier för att avgöra om man i framtiden bör analysera biomarköruttryck i lymfkörteln för prognostisk information. &lt;br/&gt;&lt;br&gt; Återfall, fjärrmetastaser, kan uppkomma till följd av spridning av cancerceller från den primära tumören genom bildandet av nya tumörer i andra organ i kroppen. Dessa kan vid bröstcancer uppkomma flera år efter det primära insjuknandet trots att inga tecken på spridd sjukdom fanns från början. Återfall verkar vara en ”gömd” process i kroppen om vilken vi vet väldigt lite. Traditionellt har man utgått från antagandet att metastasers uppkomst är en stegvis process där primärtumören sprider cancerceller till andra delar av kroppen där de bildar metastaser, att identifiera primärtumören tidigt innan dessa celler sprids har således blivit viktigt. Behandling har rekommenderats utifrån primärtumörens uttryck av prognostiska och prediktiva biomarkörer då man utgått från att dessa varit desamma som i metastaserna vid spridd sjukdom. På senare tid har denna teori ifrågasatts och man beskriver nu en parallell process där tumörceller tidigt, innan tumören är upptäckt, sprids via blodbanan och lymfsystemet ut i kroppen. De flesta av dessa spridda celler överlever inte men i en del fall utvecklas tumörcellen i andra organ och bildar då en metastas. Detta skulle betyda att de spridda omogna tumörcellerna genomgår en omvandling i andra organ och kanske uttrycker andra prognostiska och prediktiva biomarkörer vilket i sin tur skulle medföra att annan behandling skulle kunna vara aktuell vid lymfkörtelpositivsjukdom, eller vid senare uppkomna återfall av sjukdomen.&lt;br/&gt;&lt;br&gt; Skillnader i biomarköruttryck mellan brösttumören och, hos samma patient, senare uppkommet återfall i sjukdomen har påvisats i tidigare studier. Vi kunde också identifiera förändrad biologi då vi jämförde uttryck av enskilda biomarkörer mellan brösttumör och återfall i form av fjärrmetastas till lunga, lever, skelett och lokalt i bröstområdet. Patienter med återfall i bröstcancersjukdomen kan ha mer nytta av behandling som är rekommenderad utifrån analys av vävnadsprov från återfallet, än uttrycket av biomarkörer i brösttumören, för sjukdomskontroll. Rekommendation om vävnadsprovtagning från återfall är inkluderat i de Nationella riktlinjerna för behandling av bröstcancer sedan 2012.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a8f65248-f10a-4748-b3ac-4a68a4f95e7f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_t_UB.pdf">https://portal.research.lu.se/files/3279263/3971411.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2276934</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Surgery, Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>breast cancer</topic> <topic>biomarker expression</topic> <topic>lymph node metastases</topic> <topic>relapse</topic> <topic>molecular subtype classification</topic> <topic>disseminated tumour cells</topic> <topic>bone marrow</topic> <topic>prognosis</topic> <topic>mode of detection</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-48-2</identifier> <identifier type="oldLupId">3971409</identifier> <part> <detail type="volume"> <number>2013:76</number> </detail> <extent unit="pages"> <total>85</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-09-06T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>a8f65248-f10a-4748-b3ac-4a68a4f95e7f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:17:27+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:17:27+02:00</recordDateApproved> </recordInfo> </mods>

These symptoms are caused by a deficiency of dopamine (DA) in the brain, which depends on degeneration of DA neurons in the substantia nigra. The most effective treatment for PD is the DA precursor, L-DOPA. Unfortunately, within a few years, L-DOPA causes dyskinesias (abnormal involuntary movements) that are debilitating and treatment-limiting. In experimental models of PD, L-DOPA-induced dyskinesia (LID) can be improved through pharmacological modulation of glutamate or serotonin (5-HT) transmission. However, the applicability of either approach, and the underlying mechanisms, have remained unclear. &lt;br/&gt;&lt;br&gt; This thesis work has examined the effects of novel glutamate- and 5-HT modulators in animal models of PD and LID. In a first study, we evaluated Fenobam, a clinically approved antagonist of metabotropic glutamate receptor type 5 (mGluR5) in parkinsonian rats and monkeys. Compared with animals treated with L-DOPA, rats cotreated with Fenobam and L-DOPA exhibited a reduced peak severity of LID but a maintained an antiparkinsonian-like motor response. Similar results were obtained in the monkey model of PD. &lt;br/&gt;&lt;br&gt; In a second study, we examined the antiakinetic and antidyskinetic potential of novel ligands of metabotropic glutamate receptor type 4 (mGluR4), which is highly expressed in the basal ganglia. We show that neither a positive allosteric modulator (PAM) nor an orthosteric agonist of mGluR4 ameliorate LID. However, the mGluR4 PAM potentiated the antiakinetic effect of low doses of L-DOPA in certain behavioral tests. In a third study, we investigated the effects of novel, potent and selective agonists of the 5-HT1A receptor, which has emerged as an important modulator of DA release in parkinsonian subjects treated with L-DOPA. The 5-HT1A agonists examined here had superior antidyskinetic efficacy to previously used compounds. Intriguingly, one agonist completely abolished LID and only slightly interfered with the antiakinetic effect of L-DOPA. This compound was shown to markedly reduce the activity of 5-HT neurons, assessed by measuring 5-HT release in the striatum. In the fourth study, we addressed the hypothesis that mGluR5 antagonists and 5-HT1A/B agonists have distinct mechanisms of action, by examining the effects of the two drug categories on involuntary movements induced by either L-DOPA or a D1 receptor agonist. D1 agonist-induced dyskinesia was responsive to mGluR5 but not 5-HT1A/B modulation. Combined mGluR5 antagonism and 5-HT1A/B agonism exerted greater-than-additive antidyskinetic effects in L-DOPA-treated rats. However, there was no advantage in combining the two drugs when dyskinesias were elicited by the D1 receptor agonist. These results prompted the interesting hypothesis that different types of PD dyskinesias may respond differently to putative antidyskinetic interventions, depending on their main underlying mechanism.&lt;br/&gt;&lt;br&gt; To systematically address the above hypothesis, we performed a fifth study to characterize dyskinesia induced by different classes of DA receptor agonists, and examine their response to treatment. Interestingly, the phenomenology of dyskinesias was found to depend on the inducing agent. In particular, combination of D1- and D2- receptor agonists produced involuntary movements with more pronounced dystonic features. The antidyskinetic response to mGluR5 antagonism was also conditional on the inducing treatment. Only dyskinesias induced by a D1 receptor agonist, but not those induced by a D2 agonist, were significantly improved by mGluR5 antagonism. Taken together, the results of this thesis provide a robust experimental and theoretical basis for developing antidyskinetic treatments that modulate mGluR5 and 5-HT1A/B receptors.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/52fdad58-2f01-4c59-9c6b-245c24f218b1</url> </location> </relatedItem> <originInfo> <publisher>Basal Ganglia</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Parkinson&apos;s Disease</topic> <topic>L-DOPA</topic> <topic>L-DOPA-induced dyskinesia</topic> <topic>rat model of Parkinson&apos;s disease</topic> <topic>behavioural pharmacology</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-073-9</identifier> <identifier type="oldLupId">4779642</identifier> <part> <detail type="volume"> <number>2014:144</number> </detail> <extent unit="pages"> <total>89</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-12-12T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>52fdad58-2f01-4c59-9c6b-245c24f218b1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:17:52+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:17:52+02:00</recordDateApproved> </recordInfo> </mods>

To study the role of different PKC isoforms in breast cancer the expression of PCKα, δ and ε was evaluated in breast cancer tumors. In addition the effect of siRNA-mediated knockdown of the isoforms was studied in a global gene expression analysis. We found that high PKCα levels correlate with poor prognosis, high proliferation and estrogen receptor negativity. We have also seen that PKCα suppresses the expression of stanniocalcin-1 in breast cancer cells.&lt;br/&gt;&lt;br&gt; Previous reports have shown that PKCδ is a survival factor in several breast cancer cells. Here we show that Smac, a proapoptotic protein, associates with PKCδ in many different cancer cell lines. Furthermore, the PKCδ-Smac association was dissociated upon paclitaxel treatment. Upon PKC activation with TPA the PKCδ-Smac complex was stabilized and the paclitaxel-mediated dissociation and death was suppressed. The decreased cell death could potentially be caused by a competition between PKCδ and XIAP for Smac binding. We also show that activation of PKC sensitizes some breast cancer cell lines to a Smac mimetic called LBW242, a small molecule that mimic the effect of Smac. We found that the TPA+LBW242-mediated cell death was dependent on TPA-induced TNFα production. In addition the combination of TPA+LBW242 enables complex II formation and caspase-3 cleavage, a probable cause of the concomitant cell death observed.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; För att cellerna i kroppen ska fungera krävs det att proteinerna i cellerna beter sig som de ska, dvs att de signalerar på ett korrekt sätt. Det finns en mängd olika signalvägar i en cell och lika många olika mekanismer som styr signalvägarna. Mycket av det som sker i cellen regleras på ett eller annat sätt utifrån cellens genetiska kod som finns i DNA.&lt;br/&gt;&lt;br&gt; DNA:t innehåller all cellens information och om DNA:t blir skadat, i form av mutationer, kan det bidra till att cellen börjar producera defekta proteiner eller inga protein alls. Konsekvensen av ett defekt protein kan innebära felaktig signalering i cellen som bidrar till att den utvecklar canceregenskaper. Sådana canceregenskaper är exempelvis okontrollerad delning och/eller förmågan att undvika att dö. Cancer är en mångfacetterad sjukdom och det finns många olika signalvägar och proteiner som kan vara defekta i olika typer av cancer. &lt;br/&gt;&lt;br&gt; I den här avhandlingen har rollen för signalproteinet proteinkinas C (PKC) studerats i bröstcancer. PKC är en familj med flera familjemedlemmar med olika egenskaper men med den gemensamma förmågan att fosforylera andra protein och påverka deras egenskaper. &lt;br/&gt;&lt;br&gt; PKCα, aggressiva bröstcancertumörer och stanniocalcin-1&lt;br/&gt;&lt;br&gt; I paper I använde vi oss av tumörmaterial från olika bröstcancerpatienter för att studera hur uttrycket av PKC såg ut i brösttumörer. Vi såg att en PKC familjemedlem, PKCα, var uttryckt i tumörer med mer aggressiva egenskaper. Vidare såg vi i paper II att samma familjemedlem påverkade uttrycket av vissa gener däribland stanniocalcin-1 (STC1). Den exakta funktionen för STC1 är ännu okänd men STC1 tros kunna påverka olika förlopp i bröstceller som både kan påverka överlevnad men också död.&lt;br/&gt;&lt;br&gt; Man brukar tala om att det finns sex olika områden som är karakteristiska och som bidrar till cancerbildning. Dessa områden utgörs av olika signalvägar eller proteiner som är defekta och som kan ge upphov till cancer. För paper III och paper IV var fokus främst det område som handlar om cancercellens förmåga att undvika att dö dvs att undgå det som kallas cellens självmordsprogram. &lt;br/&gt;&lt;br&gt; Cancercellens självmordsprogram påverkas av PKC&lt;br/&gt;&lt;br&gt; Självmordsprogrammet ska enbart starta då en cell är så pass skadad, t ex av gifter eller mutationer, att den inte kan fungera korrekt. Regleringen av självmordsprogrammet sköts av olika proteiner. I paper III tittade vi närmre på Smac, ett av de proteiner som reglerar cellens självmordsprogram. Vid cellskada bidrar Smac till celldöd genom att hindra funktionen av ett annat protein, IAP, som annars kan bromsa eller stoppa celldöd. Vi såg att PKC-familjemedlemmen PKCδ kunde binda till Smac. Då vi aktiverade PKC kunde denna bindning stärkas och motverka celldöd av paclitaxel, ett cancergift.&lt;br/&gt;&lt;br&gt; I paper IV fortsatte vi studera celldöd genom att använda en kemisk framställd molekyl som ska likna en del av proteinet Smac. Dessa kallas därför ”Smac mimetics” vilket betyder Smac-härmare. Den Smac-härmare vi använt kallas LBW242.&lt;br/&gt;&lt;br&gt; LBW242 är tänkt att fungera genom att hindra det celldödsbromsande proteinet IAP och på så sätt underlätta för celldöd i cancerceller. LBW242 har dock ytterligare egenskaper. LBW242 och andra Smac-härmare kan påverka signaleringen från en receptor. En receptor är en mottagare och vidarebefordrare av signaler som sitter på cellens yta. Då LBW242 tillsätts ändrar receptorn sitt sätt att signalera i vissa celler. Vissa cancerceller ändrar om till ett ”celldödsläge” och cancercellen dör. Vissa cancerceller svarar dock inte med detta ”dödsläge” utan är okänsliga för LBW242. I paper IV visar vi att då man kombinerar LBW242 med ett ämne som aktiverar PKC (TPA) så dör en viss grupp bröstcancerceller. Dessa bröstcancerceller tillhör en grupp som man brukar klassificera som svårbehandlade.&lt;br/&gt;&lt;br&gt; I denna avhandling har vi sett att PKCα kan vara en markör för vissa aggressiva bröstcancer. Vidare har vi sett att PKCα kan styra regleringen av stanniocalcin-1.&lt;br/&gt;&lt;br&gt; Vi har även sett att PKCδ binder till Smac och att en intakt bindning gör cellen mindre känslig mot ett särskilt cancergift. Utöver detta ser vi att PKC-aktivering tillsammans med en Smac-härmare leder till celldöd i vissa bröstcancerceller.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e02be801-1e7a-4f19-8ee7-44502d1cdbd5</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Louise_Cornmark_DOKTORSAVHANDLING.pdf">https://portal.research.lu.se/files/3283166/3631817.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1072200</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Tumour Cell Biology, Department of Laboratory Medicine</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>breast cancer</topic> <topic>protein kinase C</topic> <topic>apoptosis</topic> <topic>cell death</topic> <topic>Smac</topic> <topic>Smac mimetics</topic> <topic>IAP</topic> <topic>stanniocalcin-1</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-11-6</identifier> <identifier type="oldLupId">3629703</identifier> <part> <detail type="volume"> <number>2013:41</number> </detail> <extent unit="pages"> <total>147</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.molecular-cancer.com/content/9/1/76</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://link.springer.com/article/10.1007%2Fs13277-011-0205-2#</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.sciencedirect.com.ludwig.lub.lu.se/science/article/pii/S0014579312002335</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-04-26T09:15:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Two cases are used in this study to shed light on such dynamics. The first case is Sweden’s strategic action within the transparency issue area, which in part defined the country’s Council Presidency in early 2001. The second case is the EU chemicals policy where Sweden, as in the transparency case, harbours strong interests. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The two studies provide opportunities for in-depth studies of the complex institutional setting and related EU negotiations within the co-decision context. Armed with a theoretical framework based on what is labelled institutional possibilities and network opportunities, the author proceeds to analyze Swedish strategic activities in the studied cases. These activities are categorized as framing; the use of expertise; manipulation; procedural tactics; leadership; mediation and coalition-building. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The framework developed to analyze Sweden’s strategies is additionally used to trace and analyze the activities of other member states (i.e., France, Italy, the UK and Finland), EU bodies, and non-governmental actors. This multi-actor approach significantly broadens the empirical and theoretical scope of analysis and understanding. The theoretical contribution consists of a synthesis of rational institutionalism and network theory – informed by the sizable literature about negotiations in international relations. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The author concludes that within co-decision procedures, the European Parliament has become an important ally – or opponent – for member states advancing national interests. The role and influence of the Council Presidency is identified as a uniquely powerful when promoting national interests through the European system. The study also demonstrates that strategies vary greatly across stages of decision-making, and that tactical approaches are configured differently depending on the context.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Avhandlingens utgångspunkt är att EU:s medlemsstater agerar mer taktiskt när starka nationella intressen står på spel. I den här studien analyseras Sveriges strategiska agerande i öppenhetsfrågan och i relation till en ny europeisk kemikalielagstiftning. Det första fallet, öppenhetsfrågan, slutförhandlades under Sveriges ordförandeskap våren 2001. Det andra fallet, kemikalielagstiftningen (förkortad REACH, vilket står för Registration, Evaluation, and Authorisation of Chemicals), är ett omfattande lagstiftningsförslag där Sverige, liksom i öppenhetsfrågan, har haft starka intressen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det teoretiska ramverket baseras på nyckelbegreppen institutional possibilities och network opportunities. Rationell institutionalism kombinerat med nätverksteori och teoribildning kring internationella förhandlingar ligger till grund för analysen. Strategiskt agerande för att tillvarata institutionellt givna möjligheter (institutional possibilities) och nätverka (network opportunities) med andra aktörer kategoriseras utifrån begreppen framing, tillhandahållande av expertis, manipulation, proceduriell taktik, ledarskap, medling samt koalitionsbyggande. Detta ramverk används även för att diskutera andra staters agerande inom samma områden liksom för att inkludera EUs institutioner samt andra ickestatliga aktörer. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Författaren kommer fram till att när ministerrådet och parlamentet gemensamt fattar beslut (co-decision procedures), så har parlamentet blivit en allt viktigare samarbetspartner och en central förhandlingsarena jämte rådet för medlemsstaterna. Vikten av ordförandeskapet i Ministerrådet för medlemsländernas möjlighet att agera taktiskt belyses. Studien visar också på att medlemsstaternas strategiska agerande varierar under olika stadier av beslutsfattande samt att olika strategier används i kombination beroende på hur beslutsproceduren utvecklas.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c2fb7592-67b9-4280-87ce-49beffceed12</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Matilda-broman-2008.pdf">https://portal.research.lu.se/files/3286968/4770580.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3118801</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Political Science, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>tactics</topic> <topic>mediation</topic> <topic>framing</topic> <topic>coalition-building</topic> <topic>expertise</topic> <topic>procedural tactics</topic> <topic>manipulation</topic> <topic>leadership</topic> <topic>co-decision procedures</topic> <topic>networks</topic> <topic>rational institutionalism</topic> <topic>openness</topic> <topic>European Parliament</topic> <topic>transparency</topic> <topic>REACH</topic> <topic>Sweden</topic> <topic>Council Presidencies</topic> <topic>negotiations</topic> <topic>EUrationell institutionalism</topic> <topic>EU</topic> <topic>förhandlingar</topic> <topic>Sverige</topic> <topic>öppenhet</topic> <topic>ordförandeskap</topic> <topic>Europaparlamentet</topic> <topic>ledarskap</topic> <topic>expertis</topic> <topic>medling och koalitionsbyggande</topic> </subject> <subject authority="lup"> <topic>Political Science</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Political Studies</title> </titleInfo> <identifier type="issn">0460-0037</identifier> <identifier type="isbn">978-88306-71-5</identifier> <identifier type="isbn">91-88306-71-2</identifier> <identifier type="oldLupId">1050333</identifier> <part> <detail type="issue"> <number>152</number> </detail> <extent unit="pages"> <total>296</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-04-19T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>c2fb7592-67b9-4280-87ce-49beffceed12</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:18:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:18:06+02:00</recordDateApproved> </recordInfo> </mods>

In the changing climate, which is most pronounced in the Arctic, the possible scenarios of greenhouse gas exchange response should be seriously considered in predictive climate modelling efforts. As a prerequisite for this, detailed studies of key processes affecting greenhouse gas exchange in the Arctic are important, as well as monitoring of its current dynamics. However, the number of such studies, carried on in high Northern latitudes is significantly smaller than for lower latitudes, and within the existing studies there is a bias towards studying the growing season.&lt;br/&gt;&lt;br&gt; The main aim of this study was to improve our process understanding of greenhouse gas exchange in the Arctic terrestrial ecosystems, including the processes taking place at low temperatures and outside the growing season. In order to achieve this some development in measurement techniques, such as automatic closed and flow-through chambers, adapted for monitoring CH4 and CO2 exchange under Arctic conditions, membrane diffusion probes to study subsurface profiles of these gases, laboratory techniques of low-temperature incubation and gas exchange studies on permafrost samples.&lt;br/&gt;&lt;br&gt; During the studies, some novel results were obtained, such as on detailed multiseasonal CH4 emission dynamics in a high Arctic fen, on late-season bursts of CH4 and CO2 at Greenland and Svalbard, and in relation to respiration and its origin in old permafrost.&lt;br/&gt;&lt;br&gt; Four years of CH4 emission monitoring data have shown that the exchange of this greenhouse gas under truly Arctic conditions is having some very special dynamics and different dominating controlling factors compared with conventional knowledge from lower latitudes. The patterns of growing season CH4 emission are highly dependent on the snow melt date. The greatest variations in fluxes between the study years was observed during the first 30-40 days after snow melt. This variability could not be explained by common factors controlling methane emission at lower latitudes: temperature and water table position. Late in the growing season CH4 emissions were found to be very similar between the study years, this despite large differences in ambient and climatic factors. In this study we try to explain these unusual patterns.&lt;br/&gt;&lt;br&gt; Late-season bursts of CH4 and CO2 coinciding with soil freezing after growing season was observed and documented in North-Eastern Greenland. A similar burst of CO2 at freezing time was documented on Svalbard. The accumulated emission during the freezing-season CH4 burst was found to be comparable in size with the growing season emission. In the study we also make an attempt to explain this phenomenon.&lt;br/&gt;&lt;br&gt; Finally samples of permafrost soils up to 500 thousands years old were found to contain living microorganisms of the same age, continuing methabolic activity and CO2 production. In this study we try to explain this unique feature of permafrost inhabitants.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Arktiska ekosystem utgör en viktig del av det globala terrestra utbytet av växthusgaser och energi med atmosfären. I ett klimat som förändras, särskilt uttalat i Arktisk, bör tänkbara framtidsprognoser av växthusgasutbytet från dessa områden övervägas noga när framtida klimat modelleras. En förutsättning för detta är detaljerade studier av nyckelprocesser som påverkar växthusgasutbytet i Arktis, liksom övervakning av dynamiken av dessa processer. Antalet studier i de nordligaste områdena är dock betydligt färre än för sydligare breddgrader och bland de studier som finns är de flesta utförda under växtsäsongen.&lt;br/&gt;&lt;br&gt; Syftet med denna studien har varit att öka förståelsen för växthusgasutbytet i arktiska terrestra ekosystem, inklusive de processer som pågår vid låga temperaturer och utanför växtsäsongen. För att uppnå detta har utveckling skett av mättekniker, som till exempel automatiskt stängda- och genomsläpps-kamrar särskilt anpassade för övervakning av CH4- och CO2-utbytet under Arktiska förhållanden, membran-sonder för att studera profiler av dessa gaser under markytan, samt laboratorietekniker där inkubation och växthusgasutbyte vid låga temperaturer har studerats på permafrostjordar.&lt;br/&gt;&lt;br&gt; Under denna studie framkom hittills okända resultat, som till exempel detaljerad CH4 dynamik från flera säsonger från en arktisk myr, sent säsongsutsläpp av CH4 och CO2 på Grönland och Svalbard, i samband med respiration och dess ursprung i gammal permafrost.&lt;br/&gt;&lt;br&gt; Fyra års övervakning av CH4 visar att utbytet av denna växthusgas har väldigt speciell dynamik i Arktiska förhållanden och kontrolleras av andra faktorer jämfört med vad som styr dynamiken på sydligare breddgrader. Växtsäsongens utsläppsmönster av CH4 beror här till stor del på när snösmältningen sker. Den största variationen i metanflöden återfanns således under de första 30-40 dagarna efter snösmältningen. Denna variation kunde inte förklaras av vad som vanligtvis kontrollerar metanutsläppen vid lägre latituder: temperatur och grundvattennivån. Sent under växtsäsongen var utsläppen av metan väldigt lika under perioden dessa studerats, detta trots stora skillnader i klimat. I denna studien försöker vi förklara dessa ovanliga utsläppsmönster.&lt;br/&gt;&lt;br&gt; Stora utsläpp av CH4 och CO2 som sammanföll med infrysning av marken efter växtsäsongen har observerats och dokumenterats på Nordöstra Grönland. Ett liknande utsläpp av CO2 har även dokumenterats på Svalbard vid infrysning av marken. De ackumulerade utsläppen av dessa utsläpp efter växtsäsongen visade sig vara av liknande storlek med utsläppen som skedde under hela växtsäsongen. I denna studie försöker vi förklara detta tidigare okända fenomen. &lt;br/&gt;&lt;br&gt; Slutligen upptäcktes levande organismer som var upp till 500 000 år gamla i jordprover från permafrostområde, där nedbrytningsprocesser och CO2 produktion fortfarande pågick. I denna studien försöker vi förklara denna unika företeelse om dessa permafrostinvånare.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b4817475-f579-4321-9aaa-70e516e39a3a</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>methane</topic> <topic>carbon dioxide</topic> <topic>greenhouse gas</topic> <topic>chamber</topic> <topic>Arctic</topic> <topic>fen</topic> <topic>permafrost</topic> </subject> <subject authority="lup"> <topic>Physical Geography</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Meddelanden från Lunds universitets geografiska institution.

In Sweden, individuals with low socioeconomic status, low social capital, and immigrants have been reported to smoke more, to stop smoking to a lesser extent, and to have higher risks of exposure to environmental tobacco smoke (ETS) compared to their counterparts. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The overall aim of this thesis has been to assess the impact of socioeconomic and demographic factors on smoking and smoking cessation in order to fill knowledge gaps for future policy formulation and implementation of effective measures to decrease tobacco smoking at the population level, as well as to decrease the socially inequitable distribution of smoking. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The study populations of this thesis are based on data from the Medical Birth Registry (MBR) in Sweden (Studies I &amp;amp; II), the Scania Public Health Survey (SPHS) 2000, Study III), and the Scania Public Health Cohort (SPHC) 2000–2005 (Study IV). In Study I, registry data indicating educational level and smoking status at the first antenatal visit in all pregnancies from 1982 to 2001 was analysed to assess the impact of educational level on smoking during pregnancy. In Study II, immigrant pregnant women were selected from the same population as Study I in order to investigate whether smoking among pregnant immigrant women in Sweden follows the epidemic model in the women’s countries of origin. For both studies, prevalences, odds ratios based on prevalences and total attributable fractions were compared for five-year intervals. In Study III, vocationally active individuals between the ages of 18 and 65 were selected from SPHS 2000 to assess the association between sociodemographic factors and exposure to ETS. This association was measured by means of logistic regression analysis. Study IV followed up baseline smokers for five years to assess the impact of social capital on smoking cessation. Cox’s proportional hazard regression was used to measure this association.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Overall, smoking prevalence declined dramatically in absolute terms, but in relative terms inequalities in smoking increased between pregnant women with different educational attainment regardless of country of origin. Similarly, the exposure to environmental tobacco smoke has been shown to be concentrated among people with low socioeconomic status. Moreover, low education and low trust have been shown to act as independent factors influencing smoking cessation. Further, a low level of social participation acts synergistically with low education in preventing smoking cessation. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Total attributable fraction has been suggested as an appropriate measure of inequalities and preferably could be used in policy making. To tackle increasing inequalities in smoking, integrative policies in tobacco control ought to consider investing in low socioeconomic groups rather than cultural patterns, where there exists less likelihood of stopping smoking and a higher risk of ETS exposure. Including aspects of social capital in smoking cessation may also benefit the overall tobacco control policies.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b2267cda-07a6-4f31-a227-1c05c856c0ed</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Environmental tobacco smoke</topic> <topic>Immigrant women</topic> <topic>Smoking trends</topic> <topic>Smoking and pregnancy</topic> <topic>Inequalities in health</topic> <topic>Attributable fraction</topic> <topic>Educational inequality</topic> <topic>Workplace exposure</topic> <topic>Passive smoking</topic> <topic>Smoking epidemic</topic> <topic>Socioeconomic status</topic> <topic>Sweden.</topic> </subject> <subject authority="lup"> <topic>Occupational Health and Environmental Health</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-93-6</identifier> <identifier type="oldLupId">1481064</identifier> <part> <detail type="volume"> <number>2009:105</number> </detail> <extent unit="pages"> <total>138</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-10-23T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>b2267cda-07a6-4f31-a227-1c05c856c0ed</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:18:32+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:18:32+02:00</recordDateApproved> </recordInfo> </mods>

Among cases treated surgically, the majority (60–70%) have a degenerative etiology, which is also easiest to repair. The general aim of this thesis was to bring research on treatment of degenerative mitral regurgitation a step further in order to improve clinical outcome after mitral valve surgery. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Patients recruited for the four studies all underwent mitral valve surgery at the Department of Cardiothoracic Surgery, Anesthesia and Intensive Care, Skåne University Hospital, Lund, Sweden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Left atrial enlargement has been identified as a marker of adverse clinical outcome in chronic severe mitral regurgitation. The extent of postoperative left atrial reverse remodeling (LARR) may be of clinical relevance, considering the relationship between left atrial enlargement and survival, heart failure, atrial fibrillation, and stroke. The first and second studies (Papers I and II) showed that most of the patients had LARR following surgery. Absence of LARR was associated with higher age (≥ 60 years), was predicted by a high preoperative left atrial volume, and did not influence survival or occurrence of new-onset chronic atrial fibrillation during follow-up. The third study (Paper III) showed that patients with severe left atrial enlargement had high mean baseline pulmonary capillary wedge pressure, which normalized early after mitral valve repair. The fourth study (Paper IV) demonstrated that right ventricular dysfunction was common. Pulmonary hypertension, although reversible after surgery, had a negative effect on right ventricular function.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, severe left atrial enlargement is highly reversible following mitral valve surgery and may reflect preoperative cardiac remodeling. A systematic echocardiographic assessment may identify early signs of remodeling due to chronic degenerative mitral regurgitation, may assist in the prioritization of surgical referrals, and may facilitate perioperative management.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Mitralisklaffen (lat. valva mitralis; valva bicuspidalis) är den klaff i hjärtat som finns mellan vänster förmak och vänster kammare. Till utseendet liknar klaffen påvens huvudbonad, mitra, varifrån namnet härstämmar. Mitralisklaffen består av två segelliknande flikar (klaffblad) med en upphängningsapparat som fäster sig i vänster-kammarens vägg. När vänster kammare kontraherar sig pressas klaffbladen ihop och förhindrar att blodet strömmar tillbaka till vänster förmak. Vid läckage i mitralisklaffen (mitralisinsufficiens) pumpas inte allt blod ut i stora kroppspulsådern utan en del läcker tillbaka genom mitralisklaffen till vänster förmak vilket förstoras efterhand. Ett läckage i mitralisklaffen kan ha flera orsaker. Majoriteten av de patienter som genomgår hjärtoperation pga. mitralisklaffsjukdom har en så kallad primär degenerativ förändring vilket betyder att själva klaffen är skadad (Figur 1). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I västvärden är läckage i mitralisklaffen den näst vanligaste klaffsjukdomen som behandlas kirurgiskt. Om man opereras i tid behöver den förväntade livslängden inte påverkas av klaffsjukdomen och därför är det av stor vikt att upptäcka läckaget tidigt. Om en hjärtoperation är aktuell ska den erbjudas utan fördröjning. Tyvärr är det fortfarande en väsentlig andel av patienterna som kommer sent till kirurgisk behandling vilket försämrar effekten av operationen. Syftet med denna avhandling var att undersöka effekterna av kroniskt läckage i mitralisklaffen på hjärtats återhämtning efter klaffoperation, undersöka om hjärtats återhämtning påverkar förekomst av komplikationer och kartlägga förändringar som sker i hjärtat under och efter klaffoperationen. Målet var att identifiera faktorer som kan påverka utfall efter klaffoperation.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En förstoring av vänster förmak avspeglar sjukdomens svårighetsgrad och är förknippat med ökad förekomst av slaganfall, oregelbunden hjärtrytm och hjärtrelaterad död. I delarbete I undersökte vi om vänster förmak ändrade sin storlek efter klaffoperationen. Volymen i vänster förmak beräknades med hjälp av hjärtultraljud enligt tre olika metoder. Vi fann att volymen på vänster förmak minskade efterhand hos majoriteten av patienterna efter en klaffoperation (en process som kallas ”reverse cardiac remodeling”). En återhämtning av vänster förmak sågs mindre ofta hos äldre patienter (≥60 år) och hos dem som hade uttalat förstorade förmak före operationen. I delarbete II undersökte vi om minskningen av vänster-förmaksvolymen påverkade överlevnaden och förekomsten av hjärtrelaterade komplikationer efter klaffoperationen. Vi kunde inte visa något sådant samband med statistisk säkerhet. I delarbete III studerade vi blodflöden och tryckförhållanden i lungkretsloppet. Ett förhöjt blodtryck i lungkärlen kan avspegla sviktande vänster förmak och kammare. Trots att hjärtultraljud visade normala värden för vänster kammare, indikerade våra resultat att det kan föreligga en skadlig påverkan av klaffläckaget på vänster kammare hos de som har en uttalad förstoring av vänster förmak. I delarbete IV fann vi med hjärtultraljud att höger kammare hade nedsatt funktion sex månader efter klaffoperationen trots utmärkta kirurgiska resultat. En möjlig förklaring till den nedsatta högerkammarfunktionen kan vara att patienten kommit för sent till kirurgisk behandling då skadorna på hjärtat har blivit bestående. En ny ultraljudsmetod (speckle tracking-derived longitudinal strain) visade sig vara ett värdefullt tillägg i bedömningen av högerkammarfunktionen före och efter klaffoperationen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis kunde vi i våra studier visa att majoriteten av studiepatienterna hade en uttalad förstoring av vänster förmak pga. läckage i mitralisklaffen och att de flesta uppvisade en minskning av vänsterförmaksvolymen efter klaffoperationen. Patienterna med utebliven vänsterförmaksåterhämtning hade ingen ökad risk för hjärtrytmstörningar, slaganfall, eller försämrad överlevnad. Mekanismen bakom vänsterförmaksförstoring kan vara ökade tryckförhållanden med åtföljande hjärthormonpåverkan varav bägge reverseras åt det normala efter klaffoperationen. Trots att vänster förmak och kammare återhämtar sig efter operationen, återfinns en högerkammarpåverkan sex månader efter kirurgi påvisad med hjärtultraljud. Detta kan bero på förhöjda tryck i lungkretsloppet som i sin tur är följd av ett kroniskt läckage i mitralisklaffen. Patienterna med kroniskt läckage i mitralisklaffen bör kontrolleras med hjärtultraljud som inkluderar bestämning av vänsterförmaksvolymen och speckle tracking-derived longitudinal strain av höger kammare i syfte att identifiera tidiga tecken på hjärtsvikt vilket i sin tur kan underlätta beslutet om och tidpunkten för en klaffoperation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/99a9b3a3-188e-4804-a2fe-91d3eaa5b6c7</url> </location> </relatedItem> <originInfo> <publisher>Thoracic Surgery, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cardiac function</topic> <topic>mitral regurgitation</topic> <topic>myocardial remodeling</topic> <topic>mitral valve repair</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-023-4</identifier> <identifier type="oldLupId">4617034</identifier> <part> <detail type="volume"> <number>2014:94</number> </detail> <extent unit="pages"> <total>64</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-09-25T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>99a9b3a3-188e-4804-a2fe-91d3eaa5b6c7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:18:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:18:35+02:00</recordDateApproved> </recordInfo> </mods>

Both diseases are influenced by a combination of genetic and environmental factors. The aim of this thesis was to identify genetic risk factors for T2D, particularly T2D associated with obesity, and for MetS. To achieve this goal, we 1) followed-up a region linked to obese T2D in an earlier genome wide linkage study; 2) studied IRS1 as a candidate gene for T2D and MetS and 3) studied the role of 28 genes, earlier identified in candidate gene- and genome wide association studies (GWAS) as susceptibility genes for T2D, in MetS.&lt;br/&gt;&lt;br&gt; In study I, extensive fine mapping by genotyping 501 haplotype tag SNPs in 27 genes within the 15 Mb region linked to obese T2D on chromosome 18p was undertaken in Botnia 2 family material. Nominal association (p &amp;lt; 0.05) between T2D, obese T2D and/or BMI in T2D patients and 74 SNPs was identified. Five of the strongest associated SNPs were selected for replication in a large Swedish T2D case-control material. In addition, six SNPs indicating strongest association in three GWAS (DGI, WTCCC and Mexican Americans) with T2D, obese T2D, BMI in T2D patients or fat mass as well as a SNP in the lipin 2 gene (LPIN2) showing association with T2D in a Dutch population (rs3745012, p = 0.03) were pursued further in the same cohort. However, no significant association was observed between the selected SNPs in the case-control material. These findings argue against common variation contributing to the observed linkage on chromosome 18p.&lt;br/&gt;&lt;br&gt; In studies II and III, the role of polymorphisms in IRS1 in T2D risk was investigated in &lt;br/&gt;&lt;br&gt; &amp;gt; 9 000 individuals. We found no association between T2D and G972R nor any of the 20 tag SNPs capturing 85% of the common variation in IRS1. These findings argue against any major involvement of common polymorphisms in IRS1 in the development of T2D.&lt;br/&gt;&lt;br&gt; In studies IV and V, we investigated the role of candidate or susceptibility genes for T2D or components of MetS in the development of MetS. In the family based Botnia prospective study (study IV) we found that polymorphisms in PPARG and ADRB1 predicted development of MetS, indicating a role of altered free fatty acid metabolism in the pathogenesis of MetS. In study V, polymorphisms in candidate genes for T2D (TCF7L2, WFS1, IGF2BP2) and obesity (FTO) predicted development of MetS and the risk to develop MetS seemed to be driven by associations with the previously reported phenotypes. These data do not support the view that the different components of MetS share a common genetic background.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3c119a26-e4bc-431f-a4c4-42afb859c957</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Genetics_of_Type_2_Diabetes_and_Metabolic_Syndrome_From_Genome_Wide_Linkage_Scans_and_Candidate_Genes_to_Genome_Wide_Association_Studies.pdf">https://portal.research.lu.se/files/3292591/1267491.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1149683</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-78-1</identifier> <identifier type="oldLupId">1267326</identifier> <part> <detail type="volume"> <number>2008:125</number> </detail> <extent unit="pages"> <total>126</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-05T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>3c119a26-e4bc-431f-a4c4-42afb859c957</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:18:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:18:38+02:00</recordDateApproved> </recordInfo> </mods>

The incidence reached 3/100,000 inhabitants in the northern Europe. The elderly were at higher risk of infection, with higher rates in males than females in most countries. Skin lesions constituted the most prevalent predisposing factor, also the most common focus of infection. The overall case fatality rate was 19%, though much higher among patients with NF and STSS (31% and 44% respectively). The T/emm distribution was highly diverse, with both similarities and striking differences between countries. emm1 was the predominant type in the majority of countries. In Denmark, Finland, and Sweden emm28 was among the most prevalent types. However the Swedish data revealed a change in type distribution, for the first time emm81, and 89 being the most common. &lt;br/&gt;&lt;br&gt; Data collected from Romanian showed a broad type distribution, with unusual types like emm65/69, 92, or 106, seldom isolated in other countries.

The study covers 25 programs broadcasted by SVT and UR during a period of four years, 2002-2005, and 12 additional programs are used as a basis for discussion. Most of the programs included in the study are productions purchased mainly from BBC Science. Thus, managing editors, producers and presenters were interviewed for the purpose of illuminating quality judgements and purchasing criteria. &lt;br/&gt;&lt;br&gt; A five stage-model of critical discourse analysis has inspired the method which emphasizes the network of communicative practices in which the media text and representation are embedded. That includes media genre, production and narrative conventions as well as the wider historical, social and political/ideological context and discourse practices of which the issues represented are a part. The critical discourse analysis has been complemented by ideas about different documentary modes of representation or basic ways of organizing documentary texts in relation to certain recurrent features or conventions. In the analysis these modes have been applied to understand the degree of transparency and editorial presence and visibility in the science documentaries. &lt;br/&gt;&lt;br&gt; The importance of the discourses presented is related to their more applied meanings. When certain descriptions, explanations and understandings of alleged human “basics” gain priority, it may affect the possibilities to define and handle very concrete social issues in a way that is inconsistent with this fundamental perspective. Thus, the ideological function of the science documentaries (as public service-program and educational media) deserves serious attention.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/33253e28-c1dd-45f9-8af3-ea33739e059a</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="SlutmanusMalinNilsson.pdf">https://portal.research.lu.se/files/3293013/1472670.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1319424</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>public service broadcasting</topic> <topic>human behavior</topic> <topic>human nature</topic> <topic>popular science</topic> <topic>science documentaries</topic> <topic>science on television</topic> <topic>Media analysis</topic> <topic>discourse analysis</topic> <topic>science and the media</topic> </subject> <subject authority="lup"> <topic>Media and Communications</topic> </subject> <relatedItem type="host"> <identifier type="isbn">91-7267-296-x</identifier> <identifier type="oldLupId">1472669</identifier> <part> <extent unit="pages"> <total>252</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-10-02T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>33253e28-c1dd-45f9-8af3-ea33739e059a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:18:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:18:40+02:00</recordDateApproved> </recordInfo> </mods>

In most cases the cause is unknown and therefore classified as essential or primary hypertension. Primary aldosteronism (PA), characterized by an inappropriate aldosterone secretion, has traditionally been estimated to account for approximately 1 % of all hypertensive cases. By using the aldosterone to renin ratio (ARR) as a screening tool, the detection of patients with PA has been facilitated. Recent international screening studies have found a high prevalence of the disease accounting for up to 10 % of hypertensive individuals. Thus, PA is recognized to be the most common cause of secondary hypertension. However, the prevalence of PA varies between study populations and the frequency among hypertensive patients in primary health care remains uncertain. When we planned these studies, no studies had previously been done in Swedish primary health care. &lt;br/&gt;&lt;br&gt; Confirmatory tests are necessary in the evaluation of patients with increased ARR.&lt;br/&gt;&lt;br&gt; The fludrocortisone suppression test (FST) is considered to be a reliable method for the&lt;br/&gt;&lt;br&gt; diagnosis of PA since it confirms an autonomous aldosterone production. However, the&lt;br/&gt;&lt;br&gt; investigational procedure varies between centres. The cut off level for aldosterone depends&lt;br/&gt;&lt;br&gt; on the analytical methods applied and there is no consensus on supplementation with NaCl.&lt;br/&gt;&lt;br&gt; Furthermore, the optimal duration of the test is unknown. The test is somewhat cumbersome&lt;br/&gt;&lt;br&gt; for the patients, and has traditionally been performed as an in-patient procedure. It is not&lt;br/&gt;&lt;br&gt; without risks, especially due to the accumulation of extracellular fluid and hypokalemia. &lt;br/&gt;&lt;br&gt; The oral captopril suppression test has less side effects compared to the FST, and could &lt;br/&gt;&lt;br&gt; potentially be useful as a confirmatory test for PA, especially in primary health &lt;br/&gt;&lt;br&gt; care. The evaluation of the test has previously been based on decreasing concentrations of &lt;br/&gt;&lt;br&gt; aldosterone. However, the evaluation of the test with the ARR for the diagnosis of PA has not&lt;br/&gt;&lt;br&gt; been assessed. Moreover, the reliability of the captopril suppression test for the diagnosis of&lt;br/&gt;&lt;br&gt; PA remains uncertain. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The general aim of this thesis is to estimate the prevalence of PA among patients with&lt;br/&gt;&lt;br&gt; hypertension in a Swedish primary care setting, and to evaluate the performance of &lt;br/&gt;&lt;br&gt; confirmatory tests in the diagnosis of PA, using modern methods for the analysis of serum &lt;br/&gt;&lt;br&gt; aldosterone and plasma renin. Reference values for different confirmatory diagnostic tests for &lt;br/&gt;&lt;br&gt; PA were obtained as part of the research project.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper I and IV hypertensive patients were screened for PA by the aldosterone to renin ratio (ARR). Patients with a high ARR were referred for confirmatory testing. In paper I, 17 of 200 patients (8.5%) with previously diagnosed and medically treated hypertension were found to have PA. In paper IV, 11 of 200 newly diagnosed and untreated hypertensive patients (5.5%), were diagnosed with PA. Thus, both screening investigations confirmed a high prevalence of the disease.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper II, reference values for aldosterone and renin were obtained for the FST in healthy subjects. The cut off value for S-aldosterone was 225 pmol/L after four days with FST or 305 pmol/L if the test was restricted to three days. Furthermore, the investigation showed that FST can be shortened to three days and that a 500 mg NaCl supplementation equivalent to the obligatory daily losses is sufficient for a reliable outcome for the test. The specific time during the day for blood sampling was not of particular importance. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper III, reference values for a 25 mg Captopril test for aldosterone, renin and ARR were obtained in healthy subjects. The results were then applied in hypertensive patients screened for PA with a high ARR. The evaluation showed that the captopril test is not reliable as a confirmatory test in the diagnosis of PA. The specificity for the discrimination between PA and patients with primary hypertension was very low, especially for patients with alterations in the renin angiotensin regulatory system. In the clinical setting, the post captopril ARR is only marginally better for the diagnosis of PA, compared to the basal ARR. However, an ARR at 120 min within the normal range strongly argues against PA. On the other hand, a high ARR (&amp;gt; 130 pmol/mIU) after the captopril test not only supports the diagnosis of PA, but also suggests the possibility of an aldosterone secreting adrenal adenoma.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, the prevalence of PA among hypertensive patients in a Swedish primary health care area is higher than previously known. Thus, the family practitioner should consider incorporating ARR screening for PA in the evaluation of patients with hypertension, not only among those with traditional signs for PA, but especially in patients who have been newly diagnosed.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Högt blodtryck (hypertoni) är en folksjukdom. Omkring 1,8 miljoner personer i Sverige, motsvarande 25 % av den vuxna befolkningen över 20 år, lider av hypertoni. I 90 % av fallen är orsaken okänd och klassificeras då som essentiell/primär hypertoni. Vid sekundär hypertoni finns det en eller flera bakomliggande orsaker till det höga blodtrycket, till exempel: förträngning av njurartären, binjuretumörer, njursjukdomar, p-piller och ökat intag av lakrits. Hypertoni är en betydande riskfaktor för hjärt-kärlsjukdom som hjärtsvikt, hjärtinfarkt, stroke, nedsatt njurfunktion, för tidig död och ökad risk för demensutveckling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En av de vanligaste orsakerna till sekundär hypertoni är primär aldosteronism (PA).&lt;br/&gt;&lt;br&gt; PA är en sjukdom utgången från binjurarna med en ökad frisättning av binjurehormonet aldosteron vilket i sin tur leder till hypertoni. Diagnostiken av PA är viktig eftersom PA kan handläggas med specifik medicinsk och ibland kirurgisk behandling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; PA beskrevs första gången 1955 av Jerome Conn och förekommer antingen som en godartad ensidig binjuretumör (Conn´s adenom) eller i form av generellt ökad frisättning från båda binjurarna (binjurebarkshyperplasi). Normalt regleras aldosteronsekretionen av hormonet renin som insöndras från njurarna men vid PA är den negativa återkopplingen till renin satt ur spel. Den förhöjda aldosteronhalten leder till en obalans av kroppssalterna natrium och kalium genom att natrium sparas och kalium utsöndras i urinen. En förhöjd natriumhalt leder till ökad vattenhalt i kroppen, vilket är en av orsakerna till hypertoni. Dessutom har aldosteron en direkt påverkan på hjärtmuskelcellerna vilket kan leda till hjärtsvikt.&lt;br/&gt;&lt;br&gt; PA ansågs tidigare vara en relativt sällsynt sjukdom vilken endast drabbade 1-2 % av patienter med hypertoni. Grundläggande för diagnosen var en oreglerad och ökad frisättning av aldosteron samt lågt kaliumvärde. Under 1990-talet, baserat på bättre biokemiska analyser framför allt kvoten mellan aldosteron och renin, den så kallade aldosteron/renin ration (ARR), har ett flertal studier av patienter med svårbehandlad hypertoni visat på en förekomst av PA hos 8-15 % av patienterna. Dessutom har man visat att ett lågt kaliumvärde, hypokalemi, på intet sätt är ett obligat fynd för diagnosen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En förhöjd ARR är dock inte tillräcklig för att fastställa diagnosen PA. Fyndet måste bekräftas med diagnostiska tester, såsom florinefhämningstest (FST) och captopriltest. Vid FST tillförs den undersökta personen ett syntetiskt binjurehormon (fludrokortison) i tablettform och vid captopriltest tillförs ett läkemedel som påverkar bildningen av aldosteron. I samband med testerna analyseras kroppens reaktion genom bestämning av renin och aldosteron i blodet. Hos friska individer minskar aldosteroninsöndringen under hämningstesterna, vilket inte är fallet vid PA eftersom insöndringen av aldosteron vid denna sjukdom är relativt opåverkad. Hos patienter med säkerställd PA-diagnos efter hämningstesterna utförs datortomografi av binjurarna för att avgöra om sjukdomen beror på en ensidig godartad tumör (Conn´s adenom) eller en dubbelsidig sjukdom (hyperplasi). Det är viktigt att diagnostisera orsaken till PA eftersom adenom behandlas med operation och hyperplasiformen medikamentellt. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Eftersom binjureförändringarna är relativt små, inte sällan mindre än 1 cm, fastställs ofta diagnosen adenom eller hyperplasi genom blodprovstagning av aldosteron i binjurevenerna. Undersökningen görs med röntgen och kräver en erfaren röntgenläkare för att få en adekvat provtagning från båda sidors binjurevener. &lt;br/&gt;&lt;br&gt; Med tanke på att de flesta publicerade vetenskapliga arbeten för att diagnostisera PA utgår från högspecialiserade enheter för utredning och behandling av svårreglerad hypertoni, finns det fortfarande en tveksamhet huruvida den beskrivna högre frekvensen av PA även gäller i ett oselekterat primärvårdsmaterial. Denna typ av undersökningar har tidigare saknats i Skandinavien. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Under senare år har nya biokemiska metoder för analys av aldosteron och renin blivit tillgängliga, vilket innebär att det finns ett stort behov av att bestämma normalvärden för aldosteron, renin och ARR. ARR utgör grunden för screening av patienter med hypertoni. Dessutom saknas vedertagna normalvärden för FST och captopriltestet med de nya känsliga biokemiska analyserna. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Huvudmålet för detta avhandlingsarbete var att undersöka prevalensen (förekomsten) av PA hos patienter med behandlad essentiell/primär hypertoni och att undersöka prevalensen av PA hos patienter med nyupptäckt och obehandlad hypertoni i ett svenskt primärvårdsområde.&lt;br/&gt;&lt;br&gt; Arbetet syftade även till att evaluera och kritiskt granska de metoder som används i diagnostiken av PA samt att utarbeta normalvärden för de nya metoderna.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete I genomgick 200 av 406 tillfrågade patienter med diagnostiserad och behandlad essentiell hypertoni screening för PA. Av de 200 deltagande patienterna diagnostiserades 17 (8,5 %) med PA. Dock kunde det inte uteslutas att den höga frekvensen av PA var beroende på en positiv selektion, d.v.s. patienter med PA hade en större benägenhet att delta i studien jämfört med patienter utan PA, så kallad bias. Dessutom hade patienterna under lång tid behandlats med hypertoniläkemedel som kan påverka bildning och insöndring av såväl renin som aldosteron. För att bättre kunna fastställa förekomsten av PA genomfördes en screeningundersökning av patienter med nydiagnostiserad och obehandlad hypertoni i primärvården. Denna screening baserades på en validerad ARR, fastställd med nyuppsatta metoder vid det lokala laboratoriet för aldosteron och renin. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete IV screenades 200 nyupptäckta obehandlade hypertonipatienter. Resultatet av detta delarbete visade att med ny diagnostik lider ca 5,5 % av patienterna i denna grupp av PA.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete II undersöktes om florinefhämningstesten (FST) kunde förenklas. I samma arbete fastställdes gränser för normalt utfall av FST baserat på nya mätmetoder för aldosteron och renin. Resultaten från undersökningen visar att testet kan förkortas till tre dagar och att salttillskottet kan minskas till 500 mg, vilket minskar såväl olägenhet som risker för patienten i samband med testet. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete III undersöktes om ett betydligt enklare test, captopriltestet, kan användas för att säkerställa diagnosen PA. Normalvärden för testet beräknades i studien. Resultaten visar att captopriltesten inte kan urskilja patienter med PA (hyperplasiformen) från patienter med essentiell/primär hypertoni. Däremot kunde testet urskilja patienter med PA på grund av binjureadenom (Conn´s adenom). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar denna avhandling att PA är vanlig bland patienter med hypertoni. Avhandlingen åskådliggör vikten av att fastställa referensvärden för de biokemiska analyserna av aldosteron och renin som används vid screening och konfirmerande diagnostiska tester. Dessutom visar avhandlingen att det är möjligt att förenkla FST.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Specialister i allmänmedicin bör uppmärksamma denna underdiagnostiserade patientgrupp då möjlighet till riktad och ibland botande behandling finns, i synnerhet då blodtrycksbehandling ofta är livslång. Långtidsresultaten vid korrekt behandling av PA är goda. Behandlingen leder till normaliserat eller mer lättbehandlat blodtryck och minskad risk för kardiovaskulära komplikationer. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I ljuset av den höga förekomsten av PA hos hypertoniker i primärvården är det på sikt viktigt att utforma ett nationellt screeningprogram för sjukdomen. &lt;br/&gt;&lt;br&gt; Högt blodtryck (hypertoni) är en folksjukdom. Omkring 1,8 miljoner personer i Sverige, motsvarande 25 % av den vuxna befolkningen över 20 år, lider av hypertoni. I 90 % av fallen är orsaken okänd och klassificeras då som essentiell/primär hypertoni. Vid sekundär hypertoni finns det en eller flera bakomliggande orsaker till det höga blodtrycket, till exempel: förträngning av njurartären, binjuretumörer, njursjukdomar, p-piller och ökat intag av lakrits. Hypertoni är en betydande riskfaktor för hjärt-kärlsjukdom som hjärtsvikt, hjärtinfarkt, stroke, nedsatt njurfunktion, för tidig död och ökad risk för demensutveckling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En av de vanligaste orsakerna till sekundär hypertoni är primär aldosteronism (PA).&lt;br/&gt;&lt;br&gt; PA är en sjukdom utgången från binjurarna med en ökad frisättning av binjurehormonet aldosteron vilket i sin tur leder till hypertoni. Diagnostiken av PA är viktig eftersom PA kan handläggas med specifik medicinsk och ibland kirurgisk behandling.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; PA beskrevs första gången 1955 av Jerome Conn och förekommer antingen som en godartad ensidig binjuretumör (Conn´s adenom) eller i form av generellt ökad frisättning från båda binjurarna (binjurebarkshyperplasi). Normalt regleras aldosteronsekretionen av hormonet renin som insöndras från njurarna men vid PA är den negativa återkopplingen till renin satt ur spel. Den förhöjda aldosteronhalten leder till en obalans av kroppssalterna natrium och kalium genom att natrium sparas och kalium utsöndras i urinen. En förhöjd natriumhalt leder till ökad vattenhalt i kroppen, vilket är en av orsakerna till hypertoni. Dessutom har aldosteron en direkt påverkan på hjärtmuskelcellerna vilket kan leda till hjärtsvikt.&lt;br/&gt;&lt;br&gt; PA ansågs tidigare vara en relativt sällsynt sjukdom vilken endast drabbade 1-2 % av patienter med hypertoni. Grundläggande för diagnosen var en oreglerad och ökad frisättning av aldosteron samt lågt kaliumvärde. Under 1990-talet, baserat på bättre biokemiska analyser framför allt kvoten mellan aldosteron och renin, den så kallade aldosteron/renin ration (ARR), har ett flertal studier av patienter med svårbehandlad hypertoni visat på en förekomst av PA hos 8-15 % av patienterna. Dessutom har man visat att ett lågt kaliumvärde, hypokalemi, på intet sätt är ett obligat fynd för diagnosen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En förhöjd ARR är dock inte tillräcklig för att fastställa diagnosen PA. Fyndet måste bekräftas med diagnostiska tester, såsom florinefhämningstest (FST) och captopriltest. Vid FST tillförs den undersökta personen ett syntetiskt binjurehormon (fludrokortison) i tablettform och vid captopriltest tillförs ett läkemedel som påverkar bildningen av aldosteron. I samband med testerna analyseras kroppens reaktion genom bestämning av renin och aldosteron i blodet. Hos friska individer minskar aldosteroninsöndringen under hämningstesterna, vilket inte är fallet vid PA eftersom insöndringen av aldosteron vid denna sjukdom är relativt opåverkad. Hos patienter med säkerställd PA-diagnos efter hämningstesterna utförs datortomografi av binjurarna för att avgöra om sjukdomen beror på en ensidig godartad tumör (Conn´s adenom) eller en dubbelsidig sjukdom (hyperplasi). Det är viktigt att diagnostisera orsaken till PA eftersom adenom behandlas med operation och hyperplasiformen medikamentellt. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Eftersom binjureförändringarna är relativt små, inte sällan mindre än 1 cm, fastställs ofta diagnosen adenom eller hyperplasi genom blodprovstagning av aldosteron i binjurevenerna. Undersökningen görs med röntgen och kräver en erfaren röntgenläkare för att få en adekvat provtagning från båda sidors binjurevener. &lt;br/&gt;&lt;br&gt; Med tanke på att de flesta publicerade vetenskapliga arbeten för att diagnostisera PA utgår från högspecialiserade enheter för utredning och behandling av svårreglerad hypertoni, finns det fortfarande en tveksamhet huruvida den beskrivna högre frekvensen av PA även gäller i ett oselekterat primärvårdsmaterial. Denna typ av undersökningar har tidigare saknats i Skandinavien. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Under senare år har nya biokemiska metoder för analys av aldosteron och renin blivit tillgängliga, vilket innebär att det finns ett stort behov av att bestämma normalvärden för aldosteron, renin och ARR. ARR utgör grunden för screening av patienter med hypertoni. Dessutom saknas vedertagna normalvärden för FST och captopriltestet med de nya känsliga biokemiska analyserna. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Huvudmålet för detta avhandlingsarbete var att undersöka prevalensen (förekomsten) av PA hos patienter med behandlad essentiell/primär hypertoni och att undersöka prevalensen av PA hos patienter med nyupptäckt och obehandlad hypertoni i ett svenskt primärvårdsområde.&lt;br/&gt;&lt;br&gt; Arbetet syftade även till att evaluera och kritiskt granska de metoder som används i diagnostiken av PA samt att utarbeta normalvärden för de nya metoderna.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete I genomgick 200 av 406 tillfrågade patienter med diagnostiserad och behandlad essentiell hypertoni screening för PA. Av de 200 deltagande patienterna diagnostiserades 17 (8,5 %) med PA. Dock kunde det inte uteslutas att den höga frekvensen av PA var beroende på en positiv selektion, d.v.s. patienter med PA hade en större benägenhet att delta i studien jämfört med patienter utan PA, så kallad bias. Dessutom hade patienterna under lång tid behandlats med hypertoniläkemedel som kan påverka bildning och insöndring av såväl renin som aldosteron. För att bättre kunna fastställa förekomsten av PA genomfördes en screeningundersökning av patienter med nydiagnostiserad och obehandlad hypertoni i primärvården. Denna screening baserades på en validerad ARR, fastställd med nyuppsatta metoder vid det lokala laboratoriet för aldosteron och renin. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete IV screenades 200 nyupptäckta obehandlade hypertonipatienter. Resultatet av detta delarbete visade att med ny diagnostik lider ca 5,5 % av patienterna i denna grupp av PA.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete II undersöktes om florinefhämningstesten (FST) kunde förenklas. I samma arbete fastställdes gränser för normalt utfall av FST baserat på nya mätmetoder för aldosteron och renin. Resultaten från undersökningen visar att testet kan förkortas till tre dagar och att salttillskottet kan minskas till 500 mg, vilket minskar såväl olägenhet som risker för patienten i samband med testet. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete III undersöktes om ett betydligt enklare test, captopriltestet, kan användas för att säkerställa diagnosen PA. Normalvärden för testet beräknades i studien. Resultaten visar att captopriltesten inte kan urskilja patienter med PA (hyperplasiformen) från patienter med essentiell/primär hypertoni. Däremot kunde testet urskilja patienter med PA på grund av binjureadenom (Conn´s adenom). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar denna avhandling att PA är vanlig bland patienter med hypertoni.

We have grouped theory and results into three main parts.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The first part focuses on the FCSR-based constructions X-FCSR and F-FCSR-H v3. For the X-FCSR family of stream ciphers we perform a severe state recovery attack. This attack works for both X-FCSR-128 and X-FCSR-256.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We then develop a generalized birthday algorithm for finding linear relations in FCSRs. This algorithm applies to the most recent and general FCSR architecture, the ring FCSR, so it can be used for analyzing the FCSR of any FCSR-based design. We apply the algorithm to produce an efficient distinguisher for F-FCSR-H v3, which was previously unbroken.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The second part of the dissertation covers topics related to the HC family of stream ciphers. First, a very general treatment of sampling methods is presented. Surprisingly, perhaps, a positive result is given. We prove that an efficient sampling method based on sampling vector weights is optimal in a given context. This sampling technique is employed to produce the best known distinguisher for HC-128.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We go on to show a few theoretical results on functions that use word rotation and xor. These results are applied to a modified variant of HC-128, and this application shows how the theory could be used in a cryptanalytical scenario. It also shows the important role of the addition operator in HC-128, without which the cipher would be much less secure.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the third part of the dissertation we analyze stream ciphers, and block ciphers to a lesser extent, using algebraic methods. We develop a simple and intuitive greedy algorithm for automatic security testing of cryptographic primitives. This is done in a black box fashion, without using any information on the internal structure of the primitives. Despite this, it is shown how structural information is revealed very clearly under certain circumstances. The main features here are some nice results for the well-known stream ciphers Trivium, Grain-128 and Grain v1.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Kryptering kan användas när man vill hålla något viktigt meddelande hemligt, till exempel vid en bankbetalning på Internet. Men hur vet man att krypteringsalgoritmen (sättet att kryptera på) är tillräckligt säker? Hur vet man att ingen kan läsa vårt meddelande eller ändra i det så att, till exempel, en överföring av pengar från ett konto till ett annat går till någon helt annan? Det är detta vi har kryptoanalys till, för att kontrollera att säkerhetskrav som ställs på krypteringsalgoritmen är uppfyllda.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Om två parter snabbt och effektivt ska skicka hemliga meddelanden mellan sig, är det vanligt att dessa två kommer överens om en hemlig nyckel som ingen annan känner till. Att båda sidor har samma hemliga nyckel kallas för ett symmetriskt kryptosystem, och det finns huvudsakligen två typer av symmetriska krypteringsalgoritmer; blockchiffer och strömchiffer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ett blockchiffer är som en låda där man stoppar in den hemliga nyckeln och det läsbara meddelandet i ena änden, och ut ur lådan kommer det oläsliga krypterade meddelandet, kryptotexten. Mottagaren kan sedan använda lådan på motsvarande sätt genom att stoppa in den hemliga nyckeln och den oläsliga kryptotexten, och får då ut den ursprungliga läsbara texten. Mottagaren har då dekrypterat meddelandet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ett strömchiffer fungerar lite annorlunda. I en strömchifferlåda stoppas huvudsakligen en hemlig nyckel in, och ut kommer en lång sekvens av nollor och ettor som ser slumpmässig ut. Denna sekvens kallas nyckelström, och när man ska kryptera ett meddelande tar man en del av denna nyckelström och lägger ihop med det läsbara meddelandet på ett mycket enkelt sätt. Den som ska dekryptera använder lådan för att först generera samma nyckelström, och lägger sedan ihop denna med kryptotexten. När man lägger ihop samma nyckelström två gånger tar dessa ut varandra så att man får tillbaka den läsbara texten igen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Mottagare som använder blockchiffer måste ha tillgång till kryptotexten. Med ett strömchiffer kan man, däremot, redan innan man har fått tillgång till kryptotexten, generera en stor mängd nyckelström i förväg. Denna kan sedan används för att mycket snabbt och enkelt få fram klartexten.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ett strömchiffer kan alltså med fördel användas när man behöver kryptera mycket data snabbt, där man inte kan vänta på att utföra hela dekrypteringen tills kryptotexten anländer. Till exempel används strömchiffer på detta sätt i bakgrunden när vi pratar i mobiltelefon, eller tittar på kabelkanaler på TV.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I denna avhandling undersöks strömchiffer, och man kan analysera dessa på många olika sätt. Det är meningen att strömchiffrens nyckelström ska se helt slumpmässig ut. Även om man får undersöka nyckelström så ska det inte kunna gå att lista ut vilken hemlig nyckeln som använts för att skapa den. Lyckas man rekonstruera nyckeln så räknas det som en mycket kraftfull attack (nyckelattack). Det ska heller inte gå att från nyckelström lista ut vad lådan innehåller, att återskapa dess tillstånd (tillståndsattack). Man ska inte ens med hjälp av statistiska metoder kunna särskilja nyckelström från en äkta slumpmässig sekvens av nollor och ettor (urskiljningsattack).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Avhandlingen består av tre huvuddelar. I den första delen visas det att de välkända strömchiffren X-FCSR och F-FCSR-H inte alls fungerar så bra som man tidigare har trott. På X-FCSR utförs en mycket kraftfull tillståndsattack, och för F-FCSR-H visas hur man effektivt kan hitta matematiska samband i nyckelström (urskiljningsattack). Den sistnämnda attacken, urskiljningsattacken, fungerar inte bara på F-FCSR-H som helhet, utan den fungerar på en av chiffrets byggstenar, FCSRen. Eftersom samma byggsten används i flera andra chiffer, kan denna metod användas för att analysera alla dessa chiffer. Slutsatsen här är att man inte bör använda sig av X-FCSR och F-FCSR-H, och dessutom behöver man tänka sig för om man bygger nya strömchiffer med hjälp av FCSRer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I den andra delen analyseras strömchiffret HC-128 och dess beståndsdelar. Där utgås det från den analys som designern till HC-128 själv presenterade. Vi byter ut en statistisk metod, en så kallad samplingsmetod mot en annan, och får därmed den bästa urskiljningsattacken som hittills visats för HC-128. Dessutom visas det att denna samplingsmetod är optimal, d.v.s. att den inte går att göra bättre. Trots detta är attacken inte tillräckligt effektiv, slutsatsen blir här att HC-128 fortfarande är användbar. Positivt är att den optimala samplingsmetoden som presenterats är generell, vilket innebär att den går att använda för att analysera andra algoritmer också.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I den sista delen görs en algebraisk analys. Denna går huvudsakligen ut på att ett strömchiffer betraktas som en matematisk funktion eller som ett ekvationssystem. En ny beräkningsmetod presenteras, och det visas hur beräkningsmetoden kan användas på nästan alla strömchiffer, men med varierande resultat. För de två kanske mest kända strömchiffren som är ämnade för hårdvarutillämpningar, Trivium och Grain-128, fungerar denna dock alldeles utmärkt, med nya kryptoanalytiska rekord som resultat. Både i form av olika urskiljningsattacker och liknande metoder.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a86c893d-6bb3-4a92-be10-6c8cc0307985</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="dissertation_pdf_version_1_0.pdf">https://portal.research.lu.se/files/3299589/3799763.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1447850</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Electrical and Information Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Stream cipher</topic> <topic>cryptanalysis</topic> <topic>FCSR</topic> <topic>state recovery</topic> <topic>linear relations</topic> <topic>optimal sampling</topic> <topic>distinguisher</topic> <topic>HC</topic> <topic>nonrandomness</topic> <topic>greedy bit set algorithm.</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Series of licentiate and doctoral dissertations</title> </titleInfo> <identifier type="issn">1654-790X</identifier> <identifier type="isbn">978-91-7473-526-0 (Online)</identifier> <identifier type="isbn">978-91-7473-525-3 (Print)</identifier> <identifier type="oldLupId">3799743</identifier> <part> <detail type="volume"> <number>50</number> </detail> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-06-17T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>a86c893d-6bb3-4a92-be10-6c8cc0307985</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:19:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-24T08:37:13Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:19:11+02:00</recordDateApproved> </recordInfo> </mods>

This thesis focuses on a number of surface proteins expressed by S. agalactiae and S. pyogenes and, more specifically, the molecular and biological characterization of these proteins.&lt;br/&gt;&lt;br&gt; The first paper describes the novel Blr protein of S. agalactiae, which together with the previously described Slr protein of S. pyogenes identifies a family of streptococcal proteins with leucine-rich repeats (LRRs). Characterization of Blr and Slr revealed that the two proteins are efficiently camouflaged by other surface components. In S. agalactiae, exposure of Blr was increased ~100-fold in a mutant lacking the polysaccharide capsule, whereas S. pyogenes mutants lacking M protein and/or protein F displayed ~20-fold increased surface exposure of Slr. It seems possible that the camouflaging structures are downregulated during some parts of the infection process, thus exposing the Blr and Slr proteins on the streptococcal surface.&lt;br/&gt;&lt;br&gt; In the second paper, we analyzed a key problem in the vaccine field, the identification of antigens that elicit protective immunity. Our studies were focused on the immune response to the S. agalactiae proteins Rib and alpha. These proteins contain a unique N-terminal region and long repetitive C-terminal sequences. The immune response against pure Rib or alpha was almost exclusively directed against the repeat region, i.e. very few antibodies were directed against the N-terminal regions. Thus, the N-terminal region is nonimmunodominant in both Rib and alpha. Nevertheless, a fusion protein comprising the N-terminal regions of Rib and alpha elicited antibodies that were protective. Importantly, studies of the S. pyogenes M22 protein showed that the N-terminal region, which is targeted by opsonic antibodies, was also nonimmunodominant. Together, these results indicate that nonimmunodominant regions are of general interest for vaccine development.&lt;br/&gt;&lt;br&gt; The third paper addresses the role of fibrinogen (Fg) in bacterial virulence. We characterized the Fg-binding B repeat region of the S. pyogenes M5 protein. In a mouse model, a mutant lacking the Fg-binding domain was severely attenuated, indicating that binding of Fg plays a key role in virulence. Similarly, a bacterial mutant lacking the most N-terminal part of the M5 protein was avirulent. Together, these data indicate that two separate regions of M5 are important for virulence. The function of bacteria-bound Fg is not known, but our data support the notion that bound Fg protects the bacteria against complement deposition and thereby against phagocytosis.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8de41c09-b183-46c2-bb4a-41a9127c1b21</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Johan_W_Kappa.pdf">https://portal.research.lu.se/files/3299838/1023611.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4665429</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Johan_W_Paper_I.pdf">https://portal.research.lu.se/files/3299840/1023618.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4669559</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Divison of Medical Microbiology</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>nonimmunodominance</topic> <topic>vaccine</topic> <topic>camouflaging</topic> <topic>Streptococcus agalactiae</topic> <topic>leucine-rich repeat</topic> <topic>Streptococcus pyogenes</topic> <topic>alpha</topic> <topic>fibrinogen</topic> <topic>M protein</topic> <topic>surface proteins</topic> <topic>Rib</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-65-0</identifier> <identifier type="oldLupId">1023575</identifier> <part> <detail type="volume"> <number>2008:12</number> </detail> <extent unit="pages"> <total>143</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-02-23T09:30:00+01:00</dateOther> <note type="additionalInfo">Information concerning the published articles present in the thesis: I: Waldemarsson, J., Areschoug T., Lindahl, G. and Johnsson, E.

Imaging studies of patients with mood disorders have demonstrated structural changes in several brain regions implicated in mood regulation. Furthermore, bipolar disorder is associated with white matter abnormalities and post mortem analysis of brain tissue from patients with mood disorders have shown glial cell pathology. Electroconvulsive therapy (ECT) and pharmacological treatment with lithium have been used in the treatment of mood disorders for over 70 respectively 60 years, but the mechanisms behind their therapeutic effects remain elusive. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We have previously shown increased neurogenesis and NG2 cell proliferation in a rat model of ECT, electroconvulsive seizures (ECS). NG2 cells can differentiate into mature myelinating oligodendrocytes in the adult brain. Moreover, given the fact they are an abundant proliferative cell type in all areas implicated in mood disorders and with a unique capacity to respond directly to neuronal signalling changes through their specialized contacts with neurons, NG2 cells are highly interesting in the context of mood disorder-associated white and grey matter changes. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In paper I we show that chronic lithium treatment unlike its stimulating effect on hippocampal neurogenesis, decreased NG2 cell proliferation in the rat dentate hilus of hippocampus, amygdala and corpus callosum. Decreased proliferation could reflect decreased oligodendrogenesis or possibly cell cycle arrest in favour of differentiation into oligodendrocytes. Thus, in paper II we investigated the effect of lithium on remyelination and oligodendrogenesis in corpus callosum after chemically induced demyelination. We found that lithium treatment during the recovery period after the demyelinating insult decreased remyelination and oligodendrogenesis. In addition, the demyelination-induced inflammation was decreased by lithium. Further studies are needed to investigate if those effects are specific for rats, the dose of lithium used and the brain region investigated. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studies from our laboratory have previously shown a low-grade glial cell activation following ECS. In paper III we show that blood-borne macrophages are recruited to the hippocampal vessel walls after ECS. It can represent the first step in an inflammatory process, but when no further signals are acquired further progression through the astrocytic end-feet layer into the brain parenchyma is halted. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; ECT’s clinical practice and general acceptance has been limited by concerns about side effects, particularly regarding memory deficits. Certain pharmacological agents administered in association with ECT may protect against amnesia. During recent years, lithium has been shown to reduce memory deficits induced by stroke, stress, head trauma etc. in rodents. In paper IV, we investigated the effect of ECS and lithium treatment on spatial memory and demonstrated robust memory loss for a hippocampus-dependent navigational task learned during the week preceding ECS. This finding was consistent in four independent investigations. However the effect of lithium treatment on ECS-induced amnesia was not as conclusive. In two identically designed studies, lithium counteracted the ECS-induced amnesia, but was neither associated with reduced cell death nor reduced microglia activation Importantly though, an anti-amnestic effect of lithium was not found in two following equally designed studies. Further investigations of ECS-related disturbances are currently ongoing in our research group.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/97420d63-0b21-4d54-8b41-3692e5e8c20d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Karin_OrreKappa.pdf">https://portal.research.lu.se/files/3299884/3349107.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3896200</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Molecular Psychiatry Unit</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>lithium</topic> <topic>electroconvulsive seizures</topic> <topic>mood disorder</topic> <topic>gliogenesis</topic> <topic>amnesia</topic> <topic>oligodendrogenesis</topic> <topic>myelination</topic> <topic>NG2 cells</topic> </subject> <subject authority="lup"> <topic>Psychiatry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-75-3</identifier> <identifier type="oldLupId">3348873</identifier> <part> <detail type="volume"> <number>2012:7</number> </detail> <extent unit="pages"> <total>150</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-01-26T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>97420d63-0b21-4d54-8b41-3692e5e8c20d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:19:17+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:19:17+02:00</recordDateApproved> </recordInfo> </mods>

The operations often include small samples of particle or cell suspensions on which separation, mixing, trapping or sorting is performed. External fields and forces are used for these operations, and this thesis is specifically focused the development of ultrasonic standing wave technology and the use of acoustic force fields to perform bioanalytical unit operations.&lt;br/&gt;&lt;br&gt; The combination of acoustic standing waves and the laminar flow in microfluidics has proven to be well suited for performing particle and cell separation. The fundamental acoustic separator used in this thesis consists of a microfluidic flow channel with a three way flow splitter (trifurcation) in the end of the channel. An acoustic standing wave field is applied to the main flow channel by attaching the transducer underneath the chip. The acoustic standing wave is however obtained perpendicular to the axial propagation of the wave field and the direction of the flow. The half wavelength resonance affects rigid particles or cells driving them into the acoustic pressure node while liquid spheres having other density and compressibility properties may move to the pressure antinode. This enables acoustic separation of different particle types. Blood has proven to be very suitable for acoustic cell manipulation. An application where lipid particles can be removed acoustically from shed blood from open heart surgery is demonstrated. An application for acoustic plasmapheresis is also shown where high quality blood plasma is generated. Different separator designs, device material, and the influence of the separation channel cross-section design are also investigated.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/742c4fbe-0a76-4261-aaee-cf3c66e82b7f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="PhD_Thesis_A_Lenshof.pdf">https://portal.research.lu.se/files/3299910/1275329.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">16396144</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>acoustic particle manipulation</topic> <topic>separation</topic> <topic>ultrasound</topic> <topic>cell handling</topic> <topic>particle handling</topic> <topic>lab on a chip</topic> <topic>Microsystem technology</topic> <topic>microfluidics</topic> <topic>standing waves</topic> </subject> <subject authority="lup"> <topic>Medical Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-628-7678-4</identifier> <identifier type="oldLupId">1275328</identifier> <part> <extent unit="pages"> <total>146</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-01-30T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>742c4fbe-0a76-4261-aaee-cf3c66e82b7f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:19:17+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:19:17+02:00</recordDateApproved> </recordInfo> </mods>

It is characterized by a prominent extracellular matrix (ECM) that is produced and maintained by relatively few cells of one type, the chondrocyte. The cartilage ECM consists of collagen fibrillar networks, proteoglycan aggregates, and a number of other molecules united in numerous interactions. This work focused at identifying catabolic events leading to cartilage destruction and functional impairment and developing tools to detect such events in patients.&lt;br/&gt;&lt;br&gt; In the first part, using a model for cartilage degradation in disease, N-terminal fragments of type IX collagen was found to be released at an intermediate time point. The two most abundant fragments were further studied and their novel C-terminals identified. These two fragments comprise most of the NC4 domain and the combined NC4 + COL3 domains, respectively. Furthermore, the identified cleavage sites were shown to be induced by matrix metalloproteinase 13 (MMP-13). &lt;br/&gt;&lt;br&gt; In the second part, the potential degradation of type IX collagen in human cartilage was investigated. It was shown that two similar type IX collagen fragments were released from cartilage explants upon MMP-13 digestion. The novel C-terminal of the fragment comprising the NC4 domain was identified. The cleavage site was found to differ between human and bovine type IX collagen. An antiserum raised against the human C-terminal neoepitope confirmed the cleavage and was used to develop an immunoassay (inhibition ELISA). This assay was used to detect elevated levels of the neoepitope in sera from arthritis patients compared to controls, indicating that this cleavage occurs in joint pathology.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/82b003d0-94fe-4649-9558-17ca1d64a57c</url> </location> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cartilage destruction</topic> <topic>matrix metalloproteinase 13</topic> <topic>ECM</topic> <topic>assay</topic> <topic>neoepitope</topic> <topic>NC4 domain</topic> <topic>Type IX collagen</topic> <topic>fragment</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-77-3</identifier> <identifier type="oldLupId">1038220</identifier> <part> <detail type="volume"> <number>2008:24</number> </detail> <extent unit="pages"> <total>108</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-03-17T09:00:00+01:00</dateOther> <note type="additionalInfo">Paper I Danfelter,M., Önnerfjord,P., and Heinegård,D.

FLT3-ITD (internal tandem duplication) and D835 mutations are found in approximately 30% and 7% of Acute Myeloid Leukemia (AML) patients respectively, and correlate with a poor prognosis, thus making the mutated receptor a potential therapeutic target. FLT3 mutations cause constitutive activation of intrinsic tyrosine kinase of the receptor, leading to ligand-independent signal transduction.&lt;br/&gt;&lt;br&gt; The aims of my studies have been to analyze the kinetics and specificity of FLT3 autophosphorylation in wild-type FLT3 and mutants, to identify novel phosphorylation sites in FLT3 receptor, to find out PTPs which can affect the signaling activity of FLT3, to investigate a novel class of tyrosine kinase inhibitors, 3, 4-diarylmaleimides for their ability to inhibit FLT3 and to determine the role of MEK5/ERK5 signaling in FLT3-ITD mediated transformation.&lt;br/&gt;&lt;br&gt; Using phosphospecific antibodies, we have identified 3 novel phosphorylation sites in FLT3, Y726, Y793 and Y842, and studied their kinetics and specificity. The additional eight phosphorylated tyrosine residues in FLT3 were shown to have different phosphorylation characteristics in the wild-type FLT3 compared to the mutated receptors. We have found that the protein tyrosine phosphatase DEP-1 serves as a negative regulator of FLT3 activation and signaling. Furthermore, 3,4-diarylmaleimides inhibitors have been found to be able to inhibit FLT3-ITD in both transfected cells as well as primary ITD-positive AML blasts leading to induction of apoptosis in those cells. These inhibitors also reduced the phosphorylation of signaling molecules downstream of FLT3-ITD such as ERK and STAT5. The last paper in the thesis revealed the anti-apoptotic effect of MEK5/ERK5 on FLT3-ITD expressing leukemia cells.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Vår kropp består av olika celler som kommunicerar med varandra genom signalering. Cellerna tar emot signaler från omgivningen med hjälp av proteiner som sätter sig fast på deras yta genom mottagare, så kallade receptorer. När receptorerna får signaler skickas de vidare in i cellkärnan där det bestäms hur cellen ska agera. Tyrosinkinasreceptorer är proteiner som sitter på cellens yta och är involverade i många processer i celler, till exempel tillväxt, celldelning, mognad, metabolism, överlevnad och rörelseförmåga. Tyrosinkinasreceptorer brukar aktiveras av en typ av ligander som kallas tillväxtfaktorer. När liganden binder till en receptor leder detta till att receptorerna slås ihop två och två, vilket i syn tur leder till fosforylering- ett sätt att skicka signaler inom celler. FLT3 tillhör familjen tyrosinkinasreceptorer och uttrycks på omogna blodceller och har en viktig roll i nybildningen av blodceller, cellernas överlevnad och celldelning. Receptorn aktiveras av en tillväxtfaktor, FLT3 ligand (FL). Det finns flera sjukdomsalstrande former av FLT3 (mutation ITD och D835Y) som leder till ständig aktivering av FLT3 dvs. utan tillväxtfaktor-stimulering, vilket leder till förändringar i signalvägarna och kan bidra till akut myeloisk leukemi (blodcancer). Dessa förändringar förekommer hos cirka 30% av patienterna med akut myeloisk leukemi (AML) och korrelerar även till en sämre prognos. AML drabbar ungefär 360 personer per år i Sverige. AML är den vanligaste formen av leukemi hos vuxna och orsakar en onormalt stor produktion av omogna blodceller vilket orsakar sjukdom. Eftersom dessa mutationer är vanligt förekommande är det viktigt att studera den här receptorn för att försöka framställa läkemedel som fungerar hämmande endast mot receptorerna med dessa mutationer men inte mot normal FLT3 eller andra receptorer. Syftet med det första arbetet var att undersöka och jämföra fosforylering/aktivering av FLT3 receptorn i både normala celler och leukemiska celler. Vi har identifierat flera nya fosforyleringsställen på FLT3 receptorn med hjälp av hemgjorda fosfospecifika antikroppar. Vi jämförde aktiveringen av specifika tyrosiner mellan vildtypsreceptorn och respektive muterade receptorer. Studien har visat att det finns såväl kvalitativa som kvantitativa skillnader i hur receptorerna fosforyleras. Det visar sig att alla tyrosinerfosforylerades olika i de tre FLT3-varianterna. Med detta har vi visat att de muterande FLT3 har specifika signaleringsvägar som är olika från den normala s.k. vildtypsreceptorn. Det är en viktig information för att kunna skapa nya behandlingsmöjligheter för AML patienter. Det andra arbetet handlar om ett proteintyrosinfosfatas (PTP), DEP-1 och hur det kontrollerar FLT3 signaling. PTP är en grupp av enzymer som tar bort fosfatgrupper från fosforylerade tyrosiner på proteiner. Vi har identifierat ett enzym, DEP-1 och visat att det är involverat i negativ reglering på fosforylering och signalering genom FLT3. Vi har också visat att DEP-1 interagerar direkt med FLT3. Akut brist av DEP-1 i human cell linje med AML orsakar förhöjd fosforylering av såväl FLT3 som MAP-kinaset ERK. DEP-1 visade sig också öka cellernas tillväxt och överlevnad. Dessa data tyder på att DEP-1 kan negativt reglera FLT3s signareringsaktivitet och kan bidra till leukemogenisk celltransformation.&lt;br/&gt;&lt;br&gt; I det tredje arbetet undersökte vi 3,4-Diarylmaleimider, en typ av kinashämmare, som nedreglerar fosforyleringen av signaleringsmolekyler nedströms om Flt3 receptorn (t ex STAT5, AKT and ERK). Denna nya klass av hämmare framkallar celldöd (apoptos) i FLT3-ITD celler redan vid låg koncentration hämmare. Eftersom dessa hämmare är så effektiva mot FLT3-ITD skulle de i framtiden kunna användas i terapi för AML patienter i kombination med kemoterapi. Det unika med denna studie är att den visar inte bara hur generell fosforylering av FLT3 påverkas av hämmare, utan en mer detaljerad undersökning har också gjorts för att undersöka hur varje fosforyleringsställe influeras. I det fjärde projektet studerade vi hur ERK5 är involverat i Flt3-medierad signalering och transformation med hjälp av en specifik hämmare av Mek5, BIX02188. Eftersom MEK5 är uppströms om ERK5, leder hämning av MEK5 till hämning av ERK5. Det visar sig att cellens överlevnad och tillväxt hämmas när de behandlas med hämmaren, speciellt celler som uttrycker FLT3-ITD. Vi undersökte även vilka signaleringsvägar som är inblandade i dessa processer och visade att BIX02188 hämmar fosforylering av AKT och ERK1/2. Denna studie visar att ERK5 otvetydigt är involverat i FLT3-medierad signalering speciellt genom FLT3-ITD receptorn och därför kan denna hämmare troligtvis också bidra till potentiella cancerterapier. Sammantaget har vi visat att FLT3 receptorn signalerar olika beroende på vilken mutation som den bär. Vidare har vi studerat olika nya hämmare av olika signaleringsmolekyler och deras roll i FLT3 signalering. Allt detta visar att det finns fortfarande mycket att studera för att hitta rätt typ av terapi för de olika AML patienterna.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b75c7eae-beb2-49e4-a14a-4d8f16b4d5fb</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="ElenaR_mont_FINAL4.pdf">https://portal.research.lu.se/files/3306098/2255723.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">6840993</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>FLT3</topic> <topic>AML</topic> <topic>RTK</topic> <topic>oncogene</topic> <topic>ERK5</topic> <topic>hematopoiesis</topic> </subject> <subject authority="lup"> <topic>Medicinal Chemistry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-59-8</identifier> <identifier type="oldLupId">2255711</identifier> <part> <detail type="volume"> <number>2011:109</number> </detail> <extent unit="pages"> <total>138</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-12-21T09:15:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The aim in paper I was to describe elderly patients with hip fracture on the basis of the American Society of Anesthesiologists’ ASA classification system and to identify preoperative risk factors in relation to the postoperative outcome measured up to 4-months after surgery. The aim in paper II was to identify perioperative risk factors in relation to postoperative outcome up to 4-months after surgery. In paper III the aim was to critically examine the Organic Brain Syndrome (OBS) Scale using the criteria and guidelines formulated by the Scientific Advisory Committee of the Medical Outcomes Trusts (SAC) for the evaluation of assessment instruments; and to investigate its relevance and suitability for use in various clinical settings. In paper IV the aim was to investigate whether an implementation of a multi-factorial intervention program including prehospital, pre-, intra- and postoperative treatment and care can reduce the incidence of acute ACS among elderly patients with hip fracture, lucid at admission to hospital.&lt;br/&gt;&lt;br&gt; Design: In paper I and II a descriptive, cohort design was used, using data prospectively registered, and data retrospectively collected from medical records and nursing charts. The design used in study III was a two-stage strategy for identifying and reviewing scientific papers. In study IV a quasi-experimental, nonequivalent comparison group design was used.&lt;br/&gt;&lt;br&gt; Results: In paper I risk factors for a poorer 4-month’s survival after hip fracture found were ‘ASA-status 3 and 4’, ‘more extensive fractures’, ‘age ≥85’, ‘male sex’, and ‘dependency in living.’ Mortality within 4-months was significantly associated with ‘ASA status 3 and 4’, ‘age ≥85 years’, ‘male sex’, ‘dementia diagnosis’, ‘Short Mental Status Questionnaire (SPMSQ) score &amp;lt;8 correct answers’, ‘prescribed drugs ≥4’, ‘hemoglobin &amp;lt;100 g/L’, ‘creatinine &amp;gt;100 micromol/L’, ‘dependency in living’, ‘unable to walk alone’, and ‘fracture other than undisplaced intracapsular’. In paper II significant perioperative risk factors for a poorer recovery and survival after hip fracture were ‘oxygen saturation (SpO2) &amp;lt;90 %’, ‘fasting time ≥12 hours’, and ‘blood transfusion ≥1 unit ’. ‘SpO2 &amp;lt;90 %’, and ‘blood transfusion ≥1’ unit were factors significantly associated with postoperative confusion, in-hospital complications and/or death within 4-months after hip fracture. A ‘postoperative hemoglobin &amp;lt;100 g/L’ was also significantly associated with postoperative confusion and in-hospital complications. In paper III the result showed that the OBS Scale in many aspects satisfies the requirements formulated by the SAC, but there is a need for additional evaluation, especially with regard to different forms of reliability, and the translation and adaptation to other languages. In paper IV the incidence of ACS was reduced by 64 % in the intervention group (29 of 131) compared to the control group (45 of 132) (p=0.031). Patients developing ACS had significantly higher levels of serious complications and 30-day mortality compared to patients without ACS.&lt;br/&gt;&lt;br&gt; Conclusion: Elderly patients acutely admitted to hospital due to a hip fracture often suffer from increased morbidity. The incidence of complications is high in this patient group. It is of great importance that patients at risk of developing postoperative complications such as ACS are identified and treated promptly in order to prevent complications. Patient’s baseline characteristics, such as high age, number of prescribed drugs, or functional status are not possible to affect. On the other hand, factors such as oxygen saturation in blood, anemia, fluid balance, pain, or the length of fasting time are possible to intervene already at an early stage.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ff8ed3f4-d16b-42cf-bd1b-cbbf5d99849b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling-kappa.KBB.080403__78.pdf">https://portal.research.lu.se/files/3306115/1057240.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">393767</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Karin Björkman Björkelund</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>postoperative confusion</topic> <topic>mortality</topic> <topic>pain</topic> <topic>fasting</topic> <topic>hypoxemia</topic> <topic>complications</topic> <topic>ASA</topic> <topic>Anemia</topic> <topic>transfusion.</topic> <topic>anesthesia</topic> </subject> <subject authority="lup"> <topic>Nursing</topic> <topic>Anesthesiology and Intensive Care</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-99-5</identifier> <identifier type="oldLupId">1057226</identifier> <part> <detail type="volume"> <number>2008:46</number> </detail> <extent unit="pages"> <total>194</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-09T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Negotiating the Musical Work’ is a piece of artistic research that attempts to merge artistic practice, qualitative research methods and critical analysis in a project concerned with contemporary performance practices, and specifically how these practices are created and transmitted in the interaction between composer and performer. By way of a critical reading of the musico-philosophical discussion of the ontology of the musical work and by way of a deconstruction of the concept of musical interpretation I propose a model in which the identity of the musical work is analysed as the result of interaction between multiple agents: composer, performer, instrument, score and electronics, among others. My critique of the debate of authenticity in musical performance leads to the identification of a number of agents associated with the concept of authenticity that also exert their influence in the field of the work. I propose that musical interpretation can be divided into two kinds: analytic interpretation and thinking-through-practice. The former is dependent on language, but also on the abstraction of musical notation. The latter is basically performed by means of action and perception, and is dependent on the perceptual system and how it is attuned to the environment. Building on Gibson’s ecological theory of perception and his concept of affordances, I further elaborate on the various modalities of this second species of musical interpretation out of which, the two main categories are thinking-through-hearing (‘concrete listening’) and thinking-through-performing. ‘The Field of the Musical Work’, is applied to the analysis of a series of projects that I performed together with six composers. These projects were documented on video and this material was further structured according to qualitative research methods. The main topics that emerge in my analysis of the collaborative work are: the impact of the regulative work-concept in contemporary practice and how we can see different kinds of open works emerge; the significance of the interaction between composer and performer and the cultural tools that are used in this dynamic (notation, instrument, electronics but I also discuss changes in the agency of composer and performer, introducing the role of the ‘curator’ and ‘artistic director’; the function of musical interpretation in the practice of both composer and performer; the role of the performer in the transmission of a musical tradition. The main artistic results of the dissertation are two CD’s: Kent Olofsson’s Corde for guitarist and orchestra, recorded with the Gothenburg symphony and Mario Venzago on Phono Suecia and Tales From the North, the complete guitar works of Per Nørgård released on Caprice records.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/759bb8db-ccf3-4e9c-8d7d-dea74fcc3f28</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="SHUT_UP__N__PLAY_final.pdf">https://portal.research.lu.se/files/3306238/1237662.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">67111612</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Malmö Faculty of Fine and Performing Arts, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Contemporary art music</topic> <topic>Collaboration</topic> <topic>Musical performance</topic> <topic>Methodology</topic> <topic>Artistic research</topic> <topic>Ontology</topic> <topic>Music philosophy</topic> <topic>Musical work</topic> <topic>Musical interpretation</topic> <topic>Performance practice</topic> </subject> <subject authority="lup"> <topic>Music</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Doctoral studies and research in fine and performing arts</title> </titleInfo> <identifier type="issn">1653-8617</identifier> <identifier type="oldLupId">1237422</identifier> <part> <detail type="issue"> <number>5</number> </detail> <extent unit="pages"> <total>392</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-14T14:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>759bb8db-ccf3-4e9c-8d7d-dea74fcc3f28</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:19:48+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:19:48+02:00</recordDateApproved> </recordInfo> </mods>

Approximately 20% of the adult population in Sweden, mainly middle-aged persons, identify themselves as family caregivers. Many of these caregivers are working and, at the same time, helping and supporting someone within the family or among friends. Among the elderly, taking care of an equally elderly spouse or partner is also common. Although the risk of illness among family caregivers is thoroughly studied and well known, providing help and support seems to have positive aspects, at least as long as the caregivers’ perceived burden is not too high. &lt;br/&gt;&lt;br&gt; The overall aim of the thesis was to study family caregivers’ perceived burden and its consequences on health related quality of life (HRQoL) and life satisfaction (LS) and find ways firstly to identify burden and secondly to describe ways to reduce burden. Data were extracted from two study populations: “Good aging in Skåne” (GÅS) and Malmö INtervention Study on Caregivers to persons with Dementia (MIND).&lt;br/&gt;&lt;br&gt; In Paper I, a cross-sectional study was conducted with data from GÅS, a general population study on persons 60 years and older. The aims were to describe the characteristics of family caregivers (n=369) and non-caregivers (n=2233) and the differences in HRQoL and LS between family caregivers and non-caregivers, and between family caregivers stratified by level of perceived strain using the same non-caregivers as a control group. The family caregivers among the participants in GÅS was identified by the question “Are you helping a family member with impaired health within or outside your household?” The results shows that family caregivers were younger, had more years of formal education, were more often cohabiting and relied less on powerful others than non-caregivers. More than 30% (n=133) of the family caregivers reported high strain. In a three-group comparison including non-caregivers and family caregivers stratified by strain, high strain was associated with lower HRQoL and LS. Furthermore, the study revealed that family caregivers experiencing low strain reported a better LS and HRQoL compared to non-caregivers. These results stress the importance of identifying burden among family caregivers and offering support in order to prevent the occurrence of high burden with its possible implications on the family caregivers LS and HRQoL. &lt;br/&gt;&lt;br&gt; Paper II is also a cross-sectional study but this paper includes data from the family caregivers (n= 343) of persons participating in GÅS, who in connection with the examination reported having informal help. The question asked was: Do you, due to impaired health, get help with household chores or personal care from someone in your family or among your friends or neighbors? After reviewing the medical protocols, five main diagnostic groups emerged among the participants: dementia disorders, heart and lung diseases, stroke, fractures, depression and a group called “other” consisting of a small number of various diagnoses. In this study we wanted to examine the associations between different diagnoses and caregiver burden. The family caregivers’ well-being, the content of and time spent on formal and informal care as well as the perceived burden was examined. A majority rated their health as very good or good but among family caregivers to persons diagnosed with heart and lung diseases and family caregivers to persons in the group “other,” ≥50% rated their health as poor. Pain and discomfort were common among family caregivers in all diagnostic groups except in the groups of stroke and fractures, and anxiety and depression were experienced by between 22- 42% of the family caregivers. A majority of the caregivers gave help with IADL more than once a week, with means ranging between 4.5 days per week in the group providing help to individuals with dementia disorders and 2 days per week within the heart and lung and “other” diagnosis groups. The family caregiver was most commonly a spouse/partner or an adult child and the average hours per week providing help on matters concerning IADL and PADL differed both between the groups and with respect to the relationship between family caregiver and care recipient within the groups. The highest reported time spent on IADL was reported in the diagnostic groups “dementia” and “heart and lung diseases,” in which spouse or partner caregivers provided help approximately 40 hours weekly. The highest reported time spent on PADL was seen among family caregivers in the group “heart and lung diseases,” with 112 hours weekly (md= 28). Caregiver Burden Scale (CBS), a 22-item scale comprising five factors of burden, was used to assess burden. The mean score of the five factors in the CBS comprises a total burden index. The highest percentage of total burden was seen among family caregivers to persons with dementia and family caregivers to persons with depression. Furthermore, family caregivers to persons with dementia and depression stood out in terms of a higher perception of burden in four out of five factors of the CBS. Burden among family caregivers to persons with dementia has been frequently studied but among caregivers to persons with depression the studies are scarce. The risk of high burden among family caregivers to persons with depression needs more attention among professionals in all areas within the healthcare sector. &lt;br/&gt;&lt;br&gt; The aim of Paper III was to examine whether a psychosocial intervention for family caregivers to persons with dementia made any differences when describing symptoms in the person they cared for. In paper III we used data from the longitudinal cohort study MIND, and examined family caregivers’ assessment and rating of symptoms of dementia before and after the family caregivers participated in a psychosocial intervention including education, information and provision of support group. Family caregivers, 129 from the intervention group and 133 among controls, were followed every 6 months during 18 months. Intellectual, emotional and activity of daily living (ADL) functions were rated by the Gottfries-Bråne-Steen-scale (GBS-scale). Family caregivers who underwent psychosocial intervention rated the intellectual and emotional symptoms of dementia significantly higher 6 months later compared to controls and the effect was sustained during the 18 month follow-up. Our findings suggest that family caregivers who underwent psychosocial intervention achieved better knowledge regarding different symptoms and behaviours and interpreted these as signs of dementia. The findings may also explain earlier findings in studies of the MIND population of less caregiver burden, higher satisfaction and the ability to delay nursing home placement in the intervention group. &lt;br/&gt;&lt;br&gt; In Paper IV, the aims were to describe the cost and cost-effectiveness of the psychosocial intervention developed within the MIND study. We analysed resource use and costs of formal care for persons with dementia (n=308) and their family caregivers (HRQoL) in the intervention group (n=153) and amongst the controls (n=155). The results showed that costs of home help services were lower among spouse caregivers in the intervention group and the cost of nursing home placement was lower in the intervention group. The family caregivers in the intervention group reported higher HRQoL both during the time when the person with dementia lived at home and after moving to nursing home. After the person with dementia had moved to nursing home, spouses in the control group reported a lower HRQoL, which can be interpreted as a positive effect of the intervention.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Anhöriga – aspekter på börda, livstillfredsställelse och effekter av stöd. &lt;br/&gt;&lt;br&gt; Med en ökande befolkning av äldre och en samtidig minskning av möjligheter till hjälpinsatser inom såväl kommunalt som landstingsstyrd vård och omsorg, kommer många av oss ta hand om äldre familjemedlemmar, släktingar och vänner. &lt;br/&gt;&lt;br&gt; Hur kommer detta att påverka oss?&lt;br/&gt;&lt;br&gt; Ungefär 20 % av den vuxna befolkningen i Sverige identifierar sig som anhöriga. Detta framkommer av en enkät bland 15000 personer över 18 år som gjordes av Socialstyrelsen 2012 på uppdrag av Socialdepartementet (National Board of Health and Welfare, 2012 a). Den fråga som ställdes var: ”Vårdar, hjälper eller stödjer du regelbundet någon eller några personer med vardagliga sysslor, personlig omsorg eller annat stöd som behövs på grund av sjukdom, funktionsnedsättning eller hög ålder?” Resultaten av denna undersökning visar att den största gruppen anhöriga finns bland medelålders, men också gruppen äldre makar och partners utgör en stor grupp. Många är såldes i förvärvsaktiv ålder och delar sin tid mellan arbete, familjeliv och att vårda och hjälpa en anhörig. Många är också i hög ålder med egna hälsoproblem. Risken för att anhörigas hälsa påverkas till det sämre är välkänd men det finns också positiva aspekter i att vårda åtminstone om anhörigas börda inte upplevs vara hög. &lt;br/&gt;&lt;br&gt; Det övergripande målet för avhandlingen var att studera anhörigas börda och hur denna påverkar livskvalitet genom att för det första; identifiera börda och dess påverkan på livskvalitet och för det andra beskriva hur bördan kan reduceras. Studierna bygger på datainsamling från Gott Åldrande i Skåne (GÅS) och Malmö Interventionsstudie för Närstående (anhöriga) med Demens, (MIND).&lt;br/&gt;&lt;br&gt; Den första studien är en tvärsnittstudie av GÅS. Målet var dels att beskriva karakteristika hos 369 anhöriga och 2233 icke anhöriga, och att studera skillnaderna i hälsorelaterad livskvalitet och livstillfredsställelse mellan anhöriga och icke-anhöriga och mellan anhöriga uppdelade utifrån upplevelse av hög eller låg börda och där icke-anhöriga utgjorde kontrollgrupp. De som var anhöriga i GÅS identifierades utifrån frågan; ”Hjälper Du någon närstående med nedsatt hälsa i eller utanför hemmet?”. Resultaten visar att de anhöriga var yngre, hade fler utbildningsår och oftare levde i parförhållande jämfört med icke-anhöriga. Mer än 30 % (n=133) av de anhöriga uppgav hög börda. En jämförelse mellan anhöriggrupperna visade att de anhöriga som uppgav hög börda också uppvisade lägre hälsorelaterad livskvalitet och lägre livstillfredsställelse. Ett annat fynd var att anhöriga som uppgav låg börda rapporterade en bättre hälsorelaterad livskvalitet och livstillfredsställelse än icke-anhöriga (Dahlrup et al, 2015). Att uppmärksamma börda och erbjuda stöd och hjälp innan bördan övergår till att påverka den anhöriges livskvalitet är viktigt för samtlig personal inom vård och omsorg.&lt;br/&gt;&lt;br&gt; Den andra studien är också den en tvärsnittsstudie baserad på GÅS och där deltagarna delats in i olika diagnosgrupper. De GÅS-deltagare (n=350), som angav att de hade stöd och hjälp genom att besvara följande fråga; ”Får du på grund av nedsatt hälsa hjälp med skötsel av hemmet och andra vardagssysslor eller personlig omvårdnad från närstående (anhöriga, vänner, grannar)?” där undersökte vi också data från de anhöriga (n=343). I denna studie ville vi undersöka om det fanns någon skillnad i upplevelsen av börda mellan anhöriga utifrån diagnosen hos den person som man vårdade. Vi studerade anhörigas självrapporterade fysiska och psykiska hälsa, insatser och tidsåtgång för såväl formell som informell vård samt upplevelser av börda. För att undersöka börda använde vi Caregiver Burden Scale (CBS) (Elmståhl, S., Malmberg, B., Annerstedt, L., 1996) som består av 22 frågor inom 5 olika områden. Medelvärdet i de fem olika områdena anger den totala bördan och denna indelades i hög och låg total börda. Den högsta totala bördan fann vi hos anhöriga till personer med diagnoserna demens och depression och bland dessa grupper fann vi också den högsta bördan i 4 av de 5 olika områdena av CBS. Bördan hos anhöriga till personer med demenssjukdom är väl studerat vilket inte är fallet bland anhöriga till äldre personer med depression. Det är viktigt för personal inom vård och omsorg att uppmärksamma risk för börda också i denna grupp av anhöriga och erbjuda adekvata former av stöd. &lt;br/&gt;&lt;br&gt; I den tredje studien ville vi undersöka hur anhöriga till personer med demenssjukdom skattade intellektuella, emotionella och motoriska symptom hos personen med demenssjukdom före och efter en intervention riktad till anhöriga bestående av information, undervisning och stödgrupper. För symtomskattningen användes Gottfries-Bråne-Steen skalan (GBS-Scale) (Bråne, 1997). För studien använde vi data från MIND och i denna delstudie ingick 129 anhöriga i interventionsgruppen och 133 i kontrollgruppen. Båda grupperna undersöktes vid baseline, dvs. före start av information, undervisning och stödgrupp för interventionsgruppen och sedan var sjätte månad under 18 månader. Anhöriga som deltog i interventionen skattade de intellektuella och emotionella symptomen högre dvs. mer uttalade, efter 6 månader än kontrollgruppen. Denna förändring kvarstod under hela uppföljningsperioden. Tolkningen av resultatet är att anhöriga genom interventionen fick bättre kunskap om sjukdomen och fick lättare att tolka olika symptom som sjukdomsyttringar (Dahlrup et al. 2011). Resultaten kan också förklara tidigare resultat som visat mindre börda, ökad tillfredsställelse och senare inflyttning till särskilda boenden i interventionsgruppen (Andrén, S., 2006, Andrén, S., Elmståhl, S., 2008 b, Andrén, S and Elmståhl, S. 2008 c).&lt;br/&gt;&lt;br&gt; I den fjärde studien var målet att beskriva kostnadseffektiviteten av den psykosociala interventionen som utvecklats i MIND-studien. Vi analyserade resursutnyttjande och kommunens kostnader för insatserna för varje enskild person med demenssjukdom (n=308) och de anhörigas självskattade hälsorelaterade livskvalitet. Interventionsgruppen bestod av 153 anhöriga och kontrollgruppen av 155 anhöriga. Anhöriga var indelade i grupper utifrån relation till den de vårdade. Resultaten visar att kostnaderna för insatser i ordinärt boende var lägre för de som vårdades av sina makar från interventionsgruppen och kostnaderna för särskilt boende var lägre i hela interventionsgruppen oavsett relation. Makar i interventionsgruppen ordnade en tidigare flytt för maken/makan till ett vårdboende jämfört med kontrollgruppen. För de vuxna barnen var det tvärtom, dvs. barnen i interventionsgruppen vårdade sina föräldrar i det ordinära boendet längre än barnen i kontrollgruppen. Anhöriga i interventionsgruppen angav också en högre hälsorelaterad livskvalitet jämfört med kontrollgruppen både då personen vistades i ordinärt boende och efter inflyttning till särskilt boende. Efter inflyttning till särskilt boende uppvisade speciellt gruppen av makar i kontrollgruppen en låg självskattad livskvalitet. Resultatet indikerar att information, undervisning och stödgrupper riktade till anhöriga kan minska risken för en försämrad livskvalitet (Dahlrup et al.2014).&lt;br/&gt;&lt;br&gt; Under de kommande decennierna, förväntas befolkningen öka och den största ökningen väntas bland personer 80 år och äldre (SCB). Detta innebär att behovet av både informell och formell vård kommer att bli stor bland denna del av befolkningen (Szebehaly och Trydegård, 2012). Kommer samhället att kunna möta kraven? Om inte, kommer anhöriga att kunna överbrygga detta gap mellan behov och resurser? &lt;br/&gt;&lt;br&gt; Också inom vård och omsorg är vi beroende av anhöriga för att upprätthålla ett gott liv för äldre i behov av hjälp. Vi måste finna vägar för att hantera framtiden på ett sätt som gynnar alla. Vi har en ganska god kunskap om situationen för anhörigvårdare för personer med demens, men vi måste få mer kunskap även om anhörigvårdare till personer med andra sjukdomstillstånd, särskilt anhöriga till personer med depression. Vi fann att anhörigvårdare till personer med depression upplevt hög belastning men forskning är begränsad trots att depression är ett vanligare tillstånd bland äldre än demens. &lt;br/&gt;&lt;br&gt; Behovet av att &quot;ta hand om vårdaren&quot; och på så sätt förbättra möjligheten för både anhöriga och vårdtagare att leva ett gott liv är en framtida utmaning. Denna utmaning måste mötas på alla möjliga sätt. Några svar föreslås i denna avhandling baseras på resultat från våra studier av anhöriga, deras upplevda börda och effekterna av information, utbildning och psykosocialt stöd.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b485e161-9d31-4411-bea9-b28d7e444a96</url> </location> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Health economic analysis</topic> <topic>intervetion</topic> <topic>quality of Life</topic> <topic>Life satisfaction</topic> <topic>Caregiver burden</topic> </subject> <subject authority="lup"> <topic>Geriatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-200-9</identifier> <identifier type="oldLupId">8169476</identifier> <part> <detail type="volume"> <number>2015:121</number> </detail> <extent unit="pages"> <total>153</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-11-26T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>b485e161-9d31-4411-bea9-b28d7e444a96</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:19:50+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:19:50+02:00</recordDateApproved> </recordInfo> </mods>

The treatment for displaced femoral neck fracture is a choice between internal fixation, total hip arthroplasty and hemiarthroplasty. As a result of several randomized trials, the treatment has shifted in Sweden from mostly internal fixation towards arthroplasties. There have been concerns about long-term arthroplasty complications such as aseptic loosening and periprosthetic fracture. In addition to investigating this issue, the focus of this thesis was on identifying the optimal treatment methods for patients with this displaced femoral neck fractures, regarding choice of implant and surgical technique.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In a 10-year follow-up of a randomized multicenter trial on 450 mentally lucid and relatively healthy patients above 70 years with displaced femoral neck fractures, patients treated with internal fixation had continuously higher rates of major complications compared to those treated with arthroplasty (46 % compared to 9 % at 10 years). Patients with successful healed fractures reported more pain and reduction of mobility at four months than those successfully treated with arthroplasty, and they never attained a better result than the latter. Those results indicate that there are no excess long-term complications after arthroplasty and refute the assumption that retaining the patient’s femoral head is beneficial.&lt;br/&gt;&lt;br&gt; The Swedish Hip Arthroplasty Register records total hip arthroplasties since 1979 and hemiarthroplasties since 2005. All hospitals performing arthroplasty surgery in Sweden are participating and completeness of recordings is near 100 %.&lt;br/&gt;&lt;br&gt; In a study based on data from the Swedish Hip Arthroplasty Register, patients with fracture-related total hip arthroplasty had a higher revision rate than those treated for other reasons (mainly osteoarthritis); 4.4 % compared to 2.9 % at 7 years. Revision rates were similar after acute fracture procedures and procedures performed secondary to failed internal fixation. Contrasting, hemiarthroplasties in the Swedish Hip Arthroplasty Register performed secondary to failed internal fixation were associated with a doubled risk of re-operation compared to those performed for acute fracture. Anterolateral surgical approach had a lower risk of total hip arthroplasty revision regardless of reason and hemiarthroplasty re-operation due to dislocation. Bipolar and uncemented hemiarthroplasties were risk factors for re-operation; the former due to dislocation, infection and periprosthetic fracture, the latter mainly due to periprosthetic fracture. Males had higher risk of total hip arthroplasty revision and hemiarthroplasty re-operation as well as higher risk of death within one year following the injury.&lt;br/&gt;&lt;br&gt; Nationwide, the proportion of hemiarthroplasty procedures for acute fractures increased from 2005 through 2009 at the expense of those secondary to failed internal fixation. Use of monoblock type implants decreased to below 1 %. Modular implants increased generally, while in 2009 bipolar implants decreased in favor of unipolar. Uncemented implants and posterior surgical approach decreased. Assumedly, those changes are results of reports from clinical trials and the Swedish Hip Arthroplasty Register. &lt;br/&gt;&lt;br&gt; In collaboration between the Swedish Hip Arthroplasty Register and the National Hip Fracture Register, all Swedish patients with displaced femoral neck fractures during 2009 received a mailed patient-reported outcomes questionnaire (79 % response rate). Patients above 70 years, with total hip arthroplasty reported less pain and were more satisfied than those treated with internal fixation or hemiarthroplasty at a median of 14 months after the fracture. Among patients below 70, those treated with total hip arthroplasty had less pain and were more satisfied than those with internal fixation.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The results presented in this thesis support the use of arthroplasty as primary treatment for displaced femoral neck fractures and indicate that use of total hip arthroplasties could be increased even further. The higher risk of re-operation with bipolar implants implies that unipolar hemiarthroplasty may be preferable for the oldest. Finally, the results suggests that anterolateral surgical approach and cemented implants are preferable in fracture-related arthroplasty surgery.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/dc1d1b60-6830-4711-be2c-2d047d9dee4b</url> </location> </relatedItem> <originInfo> <publisher>Department of Orthopaedics, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Hip fracture</topic> <topic>femoral neck fracture</topic> <topic>total hip arthroplasty</topic> <topic>hemiarthroplasty</topic> <topic>long-term results</topic> <topic>demography</topic> <topic>patient-reported outcome</topic> <topic>health-related quality of life</topic> <topic>pain</topic> <topic>satisfaction</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-07-4</identifier> <identifier type="oldLupId">2539801</identifier> <part> <detail type="volume"> <number>2012:45</number> </detail> <extent unit="pages"> <total>160</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-06-01T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>dc1d1b60-6830-4711-be2c-2d047d9dee4b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:19:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:19:58+02:00</recordDateApproved> </recordInfo> </mods>

In particular, it focuses on nonparametric revealed preference procedures. This approach has the advantage of not having to stipulate any functional form for the utility function, unlike the parametric approach which relies on finding a suitable functional form for the utility function. Many nonparametric approaches to testing rationality and weak separability are based on what is referred to in the literature as Afriat’s theorem. The significance of this theorem is that if the observed data satisfy some testable conditions, then the data may be rationalized by a well-behaved utility function that possesses such properties as being non-satiated, continuous, monotonic and concave. Chapter 2 provides a generalization of Afriat&apos;s theorem. It is shown that the concavity condition in the theorem may be relaxed to the weaker assumption of semistrict quasi-concavity. In particular, revealed preference conditions are used to check whether a finite data set can be generated by a non-satiated, continuous, monotone and semistrict quasi-concave utility function. In addition, it is shown that a data set can be checked for consistency with economic theory by solving a simple linear programming problem. Chapter 3 investigates the properties of nonparametric revealed preference tests for weak separability by means of Monte Carlo experiments. A block of goods is said to be weakly separable from all other goods when the marginal rate of substitution between any pair of goods in the separable block does not depend on the quantities consumed of any good that is not in the block. A main finding of this thesis is that the bias of the sequential test proposed by Fleissig and Whitney (2003) is low, but that the performance of the test deteriorates substantially when measurement errors are added to the data. The theoretically unbiased test by Swofford and Whitney (1994) is found to suffer from an empirical bias, most probably because the test is heavily dependent on efficient nonlinear optimization routines. Chapter 4, using a data set that comprises yearly observations from 1963-2002 examines separability structures and the demand for food in the Swedish food market. A data-orientated search method based on the multistep test procedure proposed by Jones, Elger, Edgerton and Dutkowsky (2005) is applied to find an appropriate structuring of goods in the demand analysis. Most agricultural studies assume that animalia products, beverage products and vegetabilia products constitute separable groupings. It is shown that this is a misleading assumption when analysing Swedish food data. Chapter 5, co-authored with Kerstin Enflo, addresses the issue of Western European regional productivity growth and convergence by means of data envelopment analysis (DEA), decomposing labor productivity into efficiency change, technical change and capital accumulation. A main finding is that the relative ranking of efficiency scores obtained using DEA is stable with regard to bias-corrections. The decomposition shows that, on average, capital accumulation and technological change have played roughly equally large roles, whereas efficiency changes have contributed negatively.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Denna avhandling syftar till att föreslå, utvärdera och applicera testprocedurer för rationalitet, svag separabilitet och effektivitet. Främst behandlas icke-parametriska så kallade ’revealed preference’ procedurer, vilka har fördelen att de, till skillnad från den parametriska ansatsen, inte behöver anslå någon funktionell form för nyttofunktionen. En majoritet av de testprocedurer, som finns för att testa rationalitet och svag separabilitet, är baserade på vad som i den nationalekonomiska litteraturen är kända som Afriats teorem. Signifikansen av detta teorem är att om en observerad datamängd uppfyller vissa villkor, så kan datamängden rationaliseras av en nyttofunktion som är lokalt icke-mättad, kontinuerlig, monoton och konkav. I kapitel 2 härleds en generalisering av Afriats teorem. Här visas att teoremet egentligen testar för existensen av en semistrikt kvasikonkav nyttofunktion, till skillnad från det ursprungliga teoremet, som behandlar konkava funktioner. Främst beskrivs ’revealed preference’ villkor i syfte att testa om en finit datamängd har genererats av en lokalt icke-mättad, kontinuerlig, monoton och semistrikt kvasikonkav nyttofunktion. I avhandlingen visas hur en finit datamängd kan testas för konsistens med neoklassisk ekonomisk teori genom att lösa ett linjärt optimeringsprogram. I kapitel 3 undersöks egenskaperna hos icke-parametriska ’revealed preference’ procedurer för svag separabilitet genom Monte Carlo simuleringsexperiment. En grupp av varor är svagt separabla från alla andra varor när den marginella substitutionskvoten mellan något godtyckligt par av varor i den separabla gruppen inte beror av den konsumerade kvantiteten av varor utanför gruppen. Till stor del konstateras att den teoretiska ’biasen’ i den sekventiella testprocedur, som föreslås av Fleissig och Whitney (2003) är låg, men att proceduren tenderar att vara mycket känslig för mätfel i den underliggande data genererade processen. Vidare undersöks den teoretiskt konsistenta procedur, som föreslås av Swofford och Whitney (1994). Vi finner att denna har en empirisk ’bias’, mest troligen till följd av att proceduren är starkt beroende av effektiva icke-linjära optimeringsrutiner. I kapitel 4 undersöks separabilitetsstrukturer och efterfrågan på mat på den svenska marknaden. Den datamängd, som används består av årliga observationer från 1963-2002 insamlade från nationalräkenskaperna. I syfte att finna en lämplig separabilitetsstruktur appliceras en dataorienterad sökmetod, lik den som ursprungligen föreslagits av Jones, Elger, Edgerton och Dutkowsky (2005). Oftast används i de flesta liknande studier en initialt given separabilitetsstruktur bestående av animala produkter, dryckesprodukter och produkter från växtriket. Vi visar att detta är ett felaktigt antagande för den svenska marknaden. Vidare härleder vi en teoretisk konsistent separabilitetsstruktur och skattar efterfrågan på svenska matvaror. I kapitel 5, samförfattat med Kerstin Enflo, undersöks produktivitetstillväxt och produktivitetskonvergens i västeuropeiska länder. För detta syfte används den ickeparametriska DEA metoden. Vidare analyseras orsakerna till produktionstillväxt i västeuropeiska länder genom att dekomponera arbetsproduktivitet i effektivitetsförändring, teknologisk förändring och kapitalackumulation. Vi finner att den relativa effektivitetsrankingen är stabil även efter att skattningarna korrigerats för den teoretiska ’biasen’ som karakteriserar DEA-metoden. Dekomponeringsanalysen visar att kapitalackumulering och teknologisk förändring i genomsnitt tycks ha lika stor betydelse för tillväxt i arbetsproduktivitet. Analysen visar även att förändringar i effektivitet har bidragit negativt till arbetsproduktivitet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b592e669-67d7-4883-bd58-440d362e764c</url> </location> </relatedItem> <originInfo> <publisher>Department of Economics, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Revealed preference</topic> <topic>Regional convergence</topic> <topic>Rationality</topic> <topic>Nonparametric</topic> <topic>NONPAR test</topic> <topic>LP test</topic> <topic>GARP</topic> <topic>Efficiency</topic> <topic>Data Envelopment Analysis (DEA)</topic> <topic>Afriat’s Theorem</topic> <topic>Bootstrap</topic> <topic>Swofford and Whitney test</topic> <topic>Weak separability</topic> </subject> <subject authority="lup"> <topic>Economics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Economic Series</title> </titleInfo> <identifier type="issn">0460-0029</identifier> <identifier type="oldLupId">1242530</identifier> <part> <detail type="volume"> <number>148</number> </detail> <extent unit="pages"> <total>125</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-31T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>b592e669-67d7-4883-bd58-440d362e764c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:00+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:00+02:00</recordDateApproved> </recordInfo> </mods>

The results can help decision-makers to make informed decisions over implementing lifestyle intervention, taking several dilemmas into consideration.&lt;br/&gt;&lt;br&gt; Paper I provides evidence on the cost-effectiveness of lifestyle intervention for the prevention of CVDs and T2DM. We found that 10 research groups in 9 countries demonstrated that 10 of 11 analyses of lifestyle intervention were cost-effective. Adherence to the lifestyle changes is one important predictor for the cost-effectiveness of an intervention.&lt;br/&gt;&lt;br&gt; In Paper II, we performed a long-term cost-effectiveness analysis of a randomized controlled trial of lifestyle intervention (the Swedish Björknäs study) with a decision-analytic Markov model (DAM). A differences-in-differences approach was used to control for baseline differences between the two groups, and three-year follow-up data were extrapolated over a lifetime. The DAM predicted that the lifestyle intervention was cost-saving from a societal perspective (US$-7500; +0.46 QALY), but would no longer be cost-saving if the effectiveness lasted only for the intervention period.&lt;br/&gt;&lt;br&gt; In Paper III, we revisited the cost-effectiveness of the Björknäs study with seven-year follow-up data, and compared a real-world control group to the within-trial control group to capture the “do nothing” scenario. An observational cohort, the Swedish MONICA study was used to identify a real-world general population, and matched with the Björknäs study participants by propensity score matching. The results showed the intervention to still be cost-saving with seven-year follow-up data (US$-6100; +0.45 QALY), and the benefit to be even higher when comparing a real-world general population (US$-16600; +0.35 QALY).&lt;br/&gt;&lt;br&gt; In Paper IV, we used register data on the real-life healthcare resource utilization of the Björknäs participants over a 10-year period to estimate the long-term benefit with real-life data instead of DAM-based predictions. We used a generalized estimating equation and controlled for baseline characteristics including healthcare expenditures. The results showed that the intervention group had a downward trend of outpatient and total expenditures in the long term, while the control group had an upward trend. The real-life findings from registers confirmed and complemented the DAM-based findings.&lt;br/&gt;&lt;br&gt; Lifestyle intervention has long-term benefits, and decision-makers need to implement lifestyle intervention in primary care for people at high risk of CVDs and T2DM; this will save valuable societal resources.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b87a95cc-7bfc-4d26-ac31-c338a7ccde5b</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>lifestyle intervention</topic> <topic>decision-analytic model</topic> <topic>differences-in-differences approach</topic> <topic>real-world</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-104-0</identifier> <identifier type="oldLupId">5204853</identifier> <part> <detail type="volume"> <number>2015:25</number> </detail> <extent unit="pages"> <total>73</total> </extent> </part> </relatedItem> <note type="teachingLearningHe">yes</note> <dateOther encoding="w3cdtf" type="defenseDate">2015-03-18T10:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>b87a95cc-7bfc-4d26-ac31-c338a7ccde5b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:03+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:03+02:00</recordDateApproved> </recordInfo> </mods>

At present these changes are followed as patients&apos; subjective reports and occasional measurements. Consecutive long-term measurements should provide more comprehensive information on the hearing fluctuations than the occasional audiogram used today and constitute an approach to quantify the fluctuations. Quantifications could potentially be used to define disease subgroups and to evaluate treatments. This thesis aims to introduce &apos;home audiometry&apos; to monitor hearing function in monaural FLFHL. The approaches contain assessment of other manifestations of the diseases such as frequency selectivity and frequency coding of the auditory system. &lt;br/&gt;&lt;br&gt; Long-term monitoring of binaural loudness and pitch matches showed that patients had daily fluctuations not present in normal-hearing subjects. The average day-to-day difference was considered as a measure of disease activity. This measure showed that patients with Ménière&apos;s disease had more fluctuations than patients with cochlear hydrops, and that both these groups had had more fluctuations than normal-hearing references. There was no simple relation between the measurements and simultaneous symptom ratings, corroborating the importance of the measurements. It seems possible to separate disease subgroups using long-term measurements of loudness and pitch matches. This could prove to be an essential feature in understanding the diseases and in clinical treatment trials.&lt;br/&gt;&lt;br&gt; The deviant pitch matches observed during the long-term measurements suggest changes in inner ear physiology not only related to pure tone hearing. The probable cause is excessive fluid volume in the affected inner ear. Indeed, after pressure exposure in the hypobaric pressure chamber, no average hearing threshold improvements were seen in patients with FLFHL. However, there were improvements in individual subjects regarding speech recognition, outer hair cell function, and frequency selectivity. But deteriorations were also seen, mainly in frequency selectivity. Moreover, after experimentally reducing conflicting frequency information in the affected ear, the pitch matching precision improved to some extent.&lt;br/&gt;&lt;br&gt; It is concluded that the long-term measurements provide more and comprehensive information on the hearing fluctuations than the occasional audiograms used today. More advanced measurements can be done as well, which provide more information than the blunt pure tone audiometry. Separate disease subgroups can be identified by quantifications of the fluctuations. The methods can set a new standard for the hearing evaluation of treatment in FLFHL.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/007e374c-3965-4b6f-bd79-09701d1cd3a8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Jonas_Brannstrom.pdf">https://portal.research.lu.se/files/3310372/1367218.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1323207</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>frequency coding</topic> <topic>Cochlea</topic> <topic>frequency selectivity</topic> <topic>hearing fluctuation</topic> <topic>inner ear pressure</topic> <topic>long-term measurement</topic> <topic>Ménière&apos;s disease</topic> <topic>low-frequency hearing loss</topic> <topic>loudness</topic> <topic>pitch.</topic> </subject> <subject authority="lup"> <topic>Oto-rhino-laryngology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-22-6</identifier> <identifier type="oldLupId">1367217</identifier> <part> <detail type="volume"> <number>2009:35</number> </detail> <extent unit="pages"> <total>126</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-04-25T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>007e374c-3965-4b6f-bd79-09701d1cd3a8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:05+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:05+02:00</recordDateApproved> </recordInfo> </mods>

The incidence and mortality of MI and IHD were followed using national and local registers. &lt;br/&gt;&lt;br&gt; In patients below 75 years, 28-day CFR and survival after first MI was inverse associated to the SEP of the patient’s residential area. Both incidence and 28-day CFR after first MI were inversely related to income, out-of-hospital deaths (i.e. pre-hospital deaths) having the largest differences. Preceding their MI death, low compared to high income groups had more frequently contacted the medical services. Being unmarried, independently of other risk factors, increased the risk for and dying from a first coronary event (CE). In southern Sweden deaths due to IHD occurring out-of-hospital has during the period 1992 to 2003 decreased significantly, however, being more in men. The proportion of IHD deaths occurring outside hospital was higher in younger than older cases. &lt;br/&gt;&lt;br&gt; In conclusion, living in a deprived area, having a low income and being unmarried increase the risk for a CE, decreases the chance of reaching hospital alive and increases the risk of dying from the event.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c587936d-af70-4b99-8b81-b92ca26de657</url> </location> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>gender</topic> <topic>cohort study</topic> <topic>epidemiology</topic> <topic>socio-economic factors</topic> <topic>risk factors</topic> <topic>mortality</topic> <topic>myocardial infarction</topic> <topic>ischemic heart disease</topic> <topic>coronary heart disease</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-97-9</identifier> <identifier type="oldLupId">1662333</identifier> <part> <detail type="volume"> <number>2010:81</number> </detail> <extent unit="pages"> <total>124</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-09-17T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>c587936d-af70-4b99-8b81-b92ca26de657</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:05:11Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:06+02:00</recordDateApproved> </recordInfo> </mods>

There were 27/90 haemophilia-affected foetuses of which 16 went to termination&lt;br/&gt;&lt;br&gt; and 11 were born (during 2000–2013). PND was used in 27/55 cases for mental preparation (paper I). Mutation&lt;br/&gt;&lt;br&gt; analysis found 47/77 patients to share mutations, and haplotype analysis found (51%) (24/47) to be IBD, the&lt;br/&gt;&lt;br&gt; majority of these were mild forms (paper II). Mutation and haplotype analysis among 113 families (each&lt;br/&gt;&lt;br&gt; represented by one patient) identified 32% ‘null mutations’ and 19% inhibitor among the severely affected&lt;br/&gt;&lt;br&gt; families, whereas the frequency of unique mutations was at least 65% (paper III). In 40/45 sporadic families the&lt;br/&gt;&lt;br&gt; mutation occurred within the last two generations and in 82% (23/28) the mother was hitherto an unknown carrier.&lt;br/&gt;&lt;br&gt; Conclusions: PND is increasingly used as a psychological preparation for having a child with haemophilia (paper&lt;br/&gt;&lt;br&gt; I). Mild forms of haemophilia associated with IBD have estimated ages of mutations of between two and 23&lt;br/&gt;&lt;br&gt; generations (paper II). A high frequency of unique mutations was found. The high number of inhibitor families is&lt;br/&gt;&lt;br&gt; most likely caused by many ‘null mutations’ (paper III). Due to the young age of mutations, this indicates relatives&lt;br/&gt;&lt;br&gt; having a low carrier risk (paper IV).</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4d902164-2156-4a52-b62f-9ca4fdeec9d5</url> </location> </relatedItem> <originInfo> <publisher>Department of Paediatrics, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>haemophilia</topic> <topic>factor VIII</topic> <topic>factor IX</topic> <topic>factor 8 gene</topic> <topic>factor 9 gene</topic> <topic>carriers</topic> <topic>prenatal diagnosis</topic> <topic>mutations</topic> <topic>inhibitors</topic> <topic>haplotype</topic> </subject> <subject authority="lup"> <topic>Hematology</topic> <topic>Pediatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-182-8</identifier> <identifier type="oldLupId">7991444</identifier> <part> <detail type="volume"> <number>2015:103</number> </detail> <extent unit="pages"> <total>78</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-10-16T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>4d902164-2156-4a52-b62f-9ca4fdeec9d5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:08+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:08+02:00</recordDateApproved> </recordInfo> </mods>

Seeking to combine the need for natural restoration with human development, the thesis explores to what extent more radical forms of ecological modernization can offer a basis for political compromise and open new paths to global long-term sustainability. Based on three published articles, the thesis engages with existing literature on (a) intergenerational justice, (b) sustainable development, and (c) political economy.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Written as a normative inquiry, the thesis advances the “planetary future” as a generative political metaphor. Reflecting the tension between natural dependency and human freedom, this metaphor aims not only to remind us of our shared vulnerability, as engendered by ecological decay and omnicidal weapons, but also to inspire a sense of global political agency. By taking the Enlightenment idea of a self-directing democratic future to the planetary level, the thesis hopes to turn our attention to the possibilities of human agency and help to spark a debate about what we, as an emerging planetary civilization, can hope to achieve in the century ahead.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; At the same time, the thesis seeks to offer an epistemological and political critique of its own macro-level perspective on human history, arguing that a one-sided focus on the “big picture questions” of humanity can risk relativizing local struggles for sustainability and trivialize more grounded forms of knowledge. Contrary to the managerial approach of Earth System Analysis and other similar perspectives, the thesis emphasizes the need for political deliberation and the value of diversity, both in its own right and as a source of social innovation.</abstract> <abstract lang="swe">Föreliggande avhandling argumenterar för värdet av ett långsiktigt planetärt perspektiv i politiken. Vi har blivit vana att tänka på de risker som moderniteten genererar utifrån ett vidgat tidsligt och rumsligt perspektiv (till exempel utgör år 2100 en återkommande referenspunkt för forskningen kring globala klimatförändringar). På samma sätt bör vi fråga oss vilka politiska möjligheter som mänskligheten kan tänkas ha inom motsvarande tidsrymd. Utifrån tre artiklar som tidigare publicerats i internationell vetenskaplig press syftar avhandlingen till att visa hur ett långsiktigt planetärt perspektiv kan hjälpa till att förändra vår förståelse av hållbarhetsfrågor och göra det möjligt att formulera nya politiska strategier på global nivå. Samtidigt vill avhandlingen visa på farorna med ett dylikt makroperspektiv och uppmärksamma behovet av lokal kunskap och demokratisk förankring. I takt med att hållbarhetsproblematiken blir alltmer akut ökar behovet av en medveten proaktiv politik som förmår överbrygga politiska låsningar och skapa nya berättelser om mänsklighetens framtid. Genom att utmana en rad etablerade perspektiv, från djupekologi till liberal tillväxtoptimism, hoppas avhandlingen kunna inspirera till en förnyad demokratisk debatt om dessa frågor.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ca5c9505-ca8e-46e3-a0e5-143e4cab04f4</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Rasmus-karlsson-2010.pdf">https://portal.research.lu.se/files/3310705/4770583.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">224029</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>democracy</topic> <topic>intergenerational justice</topic> <topic>Global change</topic> <topic>sustainable development</topic> <topic>innovation policy</topic> </subject> <subject authority="lup"> <topic>Political Science</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Political Studies</title> </titleInfo> <identifier type="issn">0460-0037</identifier> <identifier type="isbn">91-88306-81-x</identifier> <identifier type="isbn">978-91-88306-81-4</identifier> <identifier type="oldLupId">1718875</identifier> <part> <detail type="issue"> <number>162</number> </detail> <extent unit="pages"> <total>116</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-12-17T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>ca5c9505-ca8e-46e3-a0e5-143e4cab04f4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:09+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:09+02:00</recordDateApproved> </recordInfo> </mods>

Although mutant huntingtin is ubiquitously expressed throughout the body, HD research has mainly focused on the role of the basal ganglia. Dysfunction of these brain nuclei likely underlies motor disturbances in HD, including the conspicuous, uncontrollable, dance-like movements (chorea). However, HD is frequently complicated by other important signs and symptoms that cannot, or not solely, be attributed to basal ganglia dysfunction. Among these is unintended weight loss, which occurs in nearly all HD patients and can affect both quality of life and disease progression. Other symptoms that might occur irrespective of basal ganglia dysfunction are cognitive deterioration, psychiatric problems, sleep disturbances, cardiac failure and atrophy of skeletal muscle. &lt;br/&gt;&lt;br&gt; The past decade has seen an increasing interest in the role of mutant huntingtin in other areas of the brain and body. Although these effects are still poorly understood, their study could lead to a better understanding of the pathological mechanisms underlying HD, as well as to the identification of novel markers of disease progression and therapeutic options. The aim of this thesis was, therefore, to investigate the effects of mutant huntingtin outside the basal ganglia, especially those structures that might underlie weight loss in HD, including the hypothalamus, adipose tissue, and the gastro-intestinal tract. We found that weight loss in both HD patients and R6/2 mice (a transgenic model of HD) is not caused by changes in caloric intake or locomotor activity. Metabolism was, however, increased in R6/2 mice and this may be the cause of weight loss. Interestingly, weight loss increases with higher CAG repeat number in the mutant gene in both HD patients and R6/2 mice. This suggests that mutant huntingtin affects metabolic rate in a CAG repeat length dependant manner. The mechanism underlying this is unclear, but several regulators of metabolism, including the hypothalamus, were affected in R6/2 mice. In addition, the gastro-intestinal tract is affected in both HD patients and R6/2 mice and malabsorption of nutrients was observed in end-stage R6/2 mice. Although gastro-intestinal dysfunction is unlikely to be the cause of weight loss in HD, it may play an important role in the acceleration of weight loss in the final stages of the disease. &lt;br/&gt;&lt;br&gt; The findings in this thesis demonstrate that mutant huntingtin does not only affect the areas that have traditionally received the most attention in HD research, i.e. the basal ganglia. Other areas in the brain and body, such as the hypothalamus and gastro-intestinal tract, are also affected. Dysfunction of these structures could account for weight loss as well as several other, yet poorly understood, signs and symptoms of HD. Elucidation of the role of mutant huntingtin throughout the body could provide a better understanding of HD pathogenesis, lead to the development of novel markers of disease progression, and open new avenues for treatment.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/669f32f7-70e7-4929-865a-00255f1c0a73</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="JvdB_Avhandling_without_article3andmanucript4.pdf">https://portal.research.lu.se/files/3310887/1241628.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8775580</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="vanderburg_Kappa.pdf">https://portal.research.lu.se/files/3310889/1264717.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5263699</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Institutionen för Experimentell Medicinsk Vetenskap, Lunds Universitet</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>hypothalamus</topic> <topic>gastro-intestinal tract</topic> <topic>Huntington&apos;s disease</topic> <topic>metabolism</topic> <topic>weight loss</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85059-43-9</identifier> <identifier type="oldLupId">1241616</identifier> <identifier type="Scopus">45849140532</identifier> <part> <detail type="volume"> <number>2008:90</number> </detail> <extent unit="pages"> <total>139</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>https://www.scopus.com/pages/publications/45849140532</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-10-17T09:15:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The data collection (Paper I and II) started in year 2000 with interviews with obstetricians (n=14) concerning the meaning of being in ethically difficult situations. During 2002 to 2004 interviews with parents (n=23) about handling preterm labour and birth were performed. The quantitative studies had a cross-sectional method and a descriptive (Paper III and IV) and comparative (Paper III) design. The data collection was performed during 2007 to 2008, using a structured, anonymous and self-reported questionnaire for midwives (n=259). The midwives’ attitudes about very/extremely preterm labour and birth (Paper III) and towards a woman’s refusal of emergency cesarean section (CS) or request of CS without any medical indication (Paper IV) were investigated. The tape-recorded interviews with obstetricians were analysed using the hermeneutic-phenomenological method and with the parents the Grounded theory method was used. Descriptive and analytic statistics was used to analyse the data of the quantitative studies. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The overriding theme in Paper I was “Sympathetic responsibility in decisions of critical importance for the mother and her baby” (Paper I). Together with the five subthemes this illuminated the decision-making process, which the obstetricians went through during the situations. The parents’ main concern is shown through the core category “Inter-adapting” followed by three categories; Interacting, Reorganizing and Caring. “Inter-adapting” is a new concept and was interpreted as a mutual adaptation between the actors involved in the situation (Paper II). The midwives’ attitudes in relation to very/extremely preterm labour and birth, was that midwives at university hospitals were more likely to agree on to start interventions at an earlier gestational age than midwives at general hospitals. Obstetricians seemed to be more active in management than midwives, though midwives seemed to be more willing to disclose information to the parents (Paper III). In a conflict of interest concerning a woman’s refusal of an emergency CS for fetal distress, the midwives thought that the obstetrician should try to persuade the woman to accept the recommended CS. If a woman requests a CS without medical indication, the midwives thought that the obstetrician should comply with the woman’s’ request if she had had previous maternal or fetal complications. The reason for supporting the woman’s choice was mostly out of respect for the woman’s autonomy, although midwives at university hospitals were significant less willing to do so (Paper IV). In conclusion this thesis revealed that the obstetricians respected the autonomy of the woman during the decision-making process (Paper I). Inter-adapting strategies were used to achieve the best possible outcome for the fetus/infant (Paper II). Midwives and obstetricians with experience of handling preterm births at 21 – 28 GW develop a positive attitude to interventions at an earlier gestational age as compared to midwives without such experience (Paper III). The main focus of midwives seems to be the baby’s health and a positive birth experience for the woman and therefore they do not always agree to the woman’s refusal or request of cesarean section (Paper IV).</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ab802939-779c-4d78-b727-5e0d48ff17e7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Margaretha__Danerek__HELA_1.pdf">https://portal.research.lu.se/files/3311150/1585892.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">6164211</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>birth</topic> <topic>pregnancy</topic> <topic>critical situations</topic> <topic>decision-making</topic> <topic>attitudes</topic> <topic>midwife</topic> <topic>obstetrician</topic> </subject> <subject authority="lup"> <topic>Nursing</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-19-1</identifier> <identifier type="oldLupId">1585777</identifier> <part> <detail type="volume"> <number>2010:5</number> </detail> <extent unit="pages"> <total>136</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-07T10:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

An ACL injury is also a well known high risk factor for the development of knee osteoarthritis (OA) some decades later. Knee OA development after an ACL injury is multi-factorial. All patient variables must be further explored before better guidelines on ACL injury treatment can be issued.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I studied 100 patients with an acute complete ACL tear over 15 years and evaluated the outcome after a primary non-surgical treatment algorithm based on early neuromuscular knee rehabilitation by a physical therapist and initial activity restrictions. &lt;br/&gt;&lt;br&gt; Patients had less radiographic knee OA than in historical retrospective studies, and still had very small subjective symptoms. When OA was present, a concomitant meniscal injury treated by means of partial meniscectomy was the most important risk factor. &lt;br/&gt;&lt;br&gt; Another cohort of 29 ACL-injured patients were examined with delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) to estimate cartilage GAG content, as a proxy for cartilage integrity.&lt;br/&gt;&lt;br&gt; Results indicated knee cartilage GAG changes 2 years after an ACL injury. Patients who had sustained a meniscectomy, or had a BMI &amp;gt; 25 kg/m2, had the most impaired cartilage quality, which supports the contention that this method can detect a cartilage matrix change that may be indicative of increased risk of OA.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The data presented can help medical staff in decision-making when treating the ACL-injured patient.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/94dac16a-ecf9-413b-8275-345b19ffb2b3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Full_Final_Thesis100503.pdf">https://portal.research.lu.se/files/3311331/1599923.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1167542</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Orthopaedics, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>meniscal injury</topic> <topic>knee osteoarthritis</topic> <topic>knee radiography</topic> <topic>Anterior cruciate ligament injury (ACL)</topic> <topic>delayed gadolinium-enhanced MRI of cartilage (dGEMRIC)</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-85-6</identifier> <identifier type="oldLupId">1599916</identifier> <part> <detail type="volume"> <number>2010:69</number> </detail> <extent unit="pages"> <total>135</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-27T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane illuminated by the laser sheet can be deduced. By probing the relative occurrence of an atom or molecule in different rotational or vibrational states or by probing the Doppler shift in Rayleigh scattering, it is possible to extract the temperature. The flow field can be measured by seeding particles into the measurement volume and following them through multiple exposures. The work reported in the thesis concerns the development, improvement and applications of measurement techniques based on laser sheet illumination. &lt;br/&gt;&lt;br&gt; The aforementioned techniques are most often employed on a single shot basis, providing independent snapshots of two-dimensional (2D) data. In some examples, the measurement techniques are extended to the third spatial dimension, and in recent years, studies employing high repetition rate measurements capable of resolving the dynamics in time have become more frequent. In the thesis, a method for simultaneously extending the measurements to the third spatial dimension and to the time dimension, is presented. A high repetition rate laser and detection system is combined with oscillating mirrors, the laser sheet being scanned back and forth throughout the measurement volume. The deflections from two mirrors operated at different frequencies are combined to obtain equidistant laser sheets in the measurement region. The method is demonstrated on the Mie-scattering from a flow of droplets and is used to probe the planar laser induced fluorescence (PLIF) from the OH in a flame. Post processing methods to calculate concentrations and flame-fronts from large data sets are demonstrated.&lt;br/&gt;&lt;br&gt; Measurements of droplet concentration and size distribution in sprays, based on recording the light scattered from a laser sheet, suffer from uncertainties due to multiple scattering (MS) and attenuation of the illuminating and scattered light. A method is demonstrated here, that takes advantage of the ability to suppress the MS light by means of structured illumination. After MS suppression, the attenuation of the laser and signal light can be compensated for by comparing the transmission through the spray with the side-scattered signal. In the process, the local extinction coefficient is calculated from the Beer-Lambert law.&lt;br/&gt;&lt;br&gt; Laser based optical diagnostic techniques are in general developed for atmospheric flames under ideal laboratory conditions. In the application of the same techniques in more realistic situations, such as internal combustion (IC) engines, the harsh conditions involving vibrations, varying pressure, moving parts, limited optical access and a sooty environment have to be taken into account. Several of the measurement campaigns reported in the thesis were conducted in IC engines. Although the main goals of these campaigns were to answer combustion or engine related questions, time has also been invested in improving and adopting the measurement techniques to the existing conditions. By following the spray propagation in a light duty-diesel engine over time, knowledge was gained regarding how early spray injections should be conducted to avoid wall wetting. From high speed laser induce incandescence (LII) measurements in a heavy-duty Diesel engine, conclusions regarding soot formation and oxidation were drawn. The implementation of LII at high repetition rates in IC engines was investigated here. Challenges associated with attenuation of the laser and signal light were also addressed. Visualization of the flame jet propagation in a large-bore gas engine was made possible by means of fuel tracer LIF. Apart from the combustion related conclusions, it was shown that the image quality could be improved substantially by the use of correction optics.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; De vanligaste anledningarna till att vi eldar idag är att skapa värme, elektricitet eller mekanisk energi (som till exempel i bilar och andra fordon). När man eldar bildas kemikalier och partiklar som är skadliga för hälsa och miljö. För att minimera mängden av dessa skadliga utsläpp och för att optimera mängden energi som man kan utvinna från en viss mängd bränsle, är det viktigt att man förstår vad som händer i flamman. För att skaffa denna förståelse behöver man kunna mäta storheter som temperatur, hastigheten på gasflödena och koncentration av olika kemikalier och partiklar. Informationen från mätningarna kan, förutom att öka förståelsen för hur förbränningen påverkas av olika yttre omständigheter, användas för att förbättra noggrannheten i datormodeller utvecklade för att förutsäga förbränningsprocessen. Informationen kan också användas för att lösa tekniska problem som uppstår i specifika förbränningssammanhang. &lt;br/&gt;&lt;br&gt; Det går så klart att samla in information från flamman med hjälp av fysiska mätinstrument, som till exempel termoelement för att mäta temperatur. Problemet med dessa är de i sig påverkar flamman så att de storheter som mäts ändras. Ett termoelement påverkar till exempel gasflödet, kan agera som katalysator för vissa kemiska reaktioner och kyler lokalt gasen i flamman. Den temperatur som mäts blir då annorlunda än vad den varit om inget termoelement stört flamman. Ett vanligt sätt att samla in information från en flamma, utan att påverka den, är att istället fotografera den med en kamera. Som ljuskälla används i regel en kort laserpuls, formad till ett tunt laserark (istället för blixt som används vid vanlig fotografering). Att använda ett laserark som ljuskälla jämfört med att detektera det ljus som naturligt strålar ut från flamman, har flera fördelar. Dels kan laserarket göras så kort att inget hinner hända i flamman under exponeringen. Man får alltså en bild av hur det är under just tidpunkten då laserarket passerar istället för en suddig medelvärdesbild av vad som händer under kamerans exponeringstid (som att fotografera något som rör sig snabbt med eller utan blixt). Dessutom kommer ljuset, som detekteras av kameran, bara från det område som laserarket belyser, alltså en skarp genomskärning istället för ett medelvärde från hela djupet av flamman. Men den största fördelen är nog ändå att man genom att justera färgen på laserljuset kan välja vilken typ av information som bilden kommer innehålla. Många av molekylerna som finns i flamman reagerar bara på vissa specifika färger. Genom att välja ett laserljus med en färg som överensstämmer med den molekyl man är intresserad av får man en signal som innehåller information om fördelningen av detta ämne i genomskärningen av flamman. Man kan även välja att anpassa laserljusets färg för att se hur snabbt molekylerna vibrerar och roterar, och med denna information räkna ut temperaturen i flamman. Vill man veta flödeshastigheterna -- alltså hur snabbt och i vilken riktning gasen rör sig i varje punkt i flamman -- kan man tillsätta små partiklar, belysa dessa med två laserark efter varandra och se hur långt partiklarna flyttat sig under tiden mellan exponeringarna.&lt;br/&gt;&lt;br&gt; Historiskt sett har den utrustning som använts för att fotografera i flammorna (lasrarna och kamerorna) kunnat användas med en uppdateringsfrekvens på ett tiotal bilder per sekund. Under tiden mellan två bilder har det då hunnit hända så mycket att det inte längre går att säga om de är tagna direkt efter varandra eller med längre tid emellan. I den här avhandlingen har en relativt ny typ av laser och kamerautrustning använts, som kan användas med flera tusen exponeringar per sekund. På så sätt kan man studera vad som händer i flamman över tiden och inte bara hur läget är vid en specifik tidpunkt. Lite som att spela in en film istället för att ta stillbilder. Dessutom har en teknik utvecklats där laserarket hastigt skannas fram och tillbaka i flamman. På så sätt kan information från alla tre rumsliga dimensioner samlas in och resultatet blir en 3D-film.&lt;br/&gt;&lt;br&gt; Det finns mycket att göra för att förbättra mätmetoderna utöver att utöka dom till fler dimensioner. För att mätningarna ska ha hög noggrannhet krävs till exempel att man vet hur många fotoner (ljuspartiklar) som befinner sig i laserarket. Fotonernas antal kan dock ändra sig med tiden, då de sprids eller absorberas av partiklarna och molekylerna i mätvolymen. Det spridda ljuset, som normalt skulle registreras av kameran, kan också absorberas eller spridas innan det kommit fram till kameran. Båda de ovan nämnda effekterna ger upphov till att mindre ljus registreras och det finns risk att datan feltolkas. Det finns också en risk att redan spridda fotoner sprids en eller flera gånger till, så kallad multipelspridning. Multipelspridningarna kan ske från positioner som ligger utanför laserarket och därmed ge upphov till en falsk signal. I den här avhandlingen demonstreras en metod som kan kompensera för ovan nämnda fel. För att särskilja det multipelspridda ljuset från det som bara spridits en gång introduceras ett randmönster i laserarket. De fotoner som sprids flera gånger förlorar randstrukturen och kan på matematisk väg särskiljas från de som bara spridits en gång och därmed har randmönstret bevarat. När de multipelspridda fotonerna rensats bort beter sig dämpningen av ljuset i laserarket och den spridda signalen på ett matematiskt förutsägbart sätt. Från den detekterade signalen som kommer från ett visst område i mätvolymen, kan man därmed räkna ut hur mycket ljuset dämpats i detsamma område. Den informationen kan då användas för att räkna ut den faktiska mängden fotoner i den intilliggande mätvolymen och på så sätt kan man undvika felet som dämpningen av signalen annars skulle gett upphov till där.&lt;br/&gt;&lt;br&gt; Mycket av arbetet som rapporteras i avhandlingen har alltså handlat om att utveckla nya mätmetoder. Men det är en sak att en mätmetod fungerar i en öppen mätvolym i en laboratoriemiljö, och en helt annan sak att få det att fungera tillfredsställande i praktiska sammanhang, som i förbränningsmotorer. Avhandlingen behandlar även mätningar gjorda i förbränningsmotorer. Dessa mätningarna och analyserna av dom har lett till: ökad förståelse för hur sot bildas och oxideras i en dieselmotor, hur man kan lösa problemet med att bränslesprayen träffar cylinderväggen vid tidig insprutning av bränsle i små dieselmotorer och hur jetflamman utvecklas och tänder gasen i en gasmotor med förkammartändning. Under dessa mätningar har en rad utmaningar kopplade till mätningar i förbränningsmotorer stötts på och antagits. Ett exempel på en sådan utmaning är de optiska fel som skapas när ljuset bryts i de krökta fönster som sitter i motorn. Optik och mjukvara har utvecklats som kompenserar för dessa fel, som annars hade lett till suddiga och förvrängda bilder. Ett annat exempel är att en diagnostikmetod som inriktar sig på att detektera sot har undersökts med hänseende till hur den påverkas av att användas i tidsupplösta mätningar i en förbränningsmotor. &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har forskningen resulterat i att en diagnostisk metod tagits fram för att öka noggrannheten i mätningar genom att kompensera för dämpningen och multipelspridningen av ljuset i mätvolymen. En mätmetod har demonstrerats som möjliggör tidsupplösta mätningar i 3D. Mätmetoder har anpassats för att kunna mäta i de mer krävande miljöer som skapas inne i förbränningsmotorer. Datan från de sistnämnda mätningarna har analyserats och lett till en ökad förståelse kring vissa processer i diesel- och gasmotorer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d4fceb27-c990-4ea8-9f03-92646e9e64ef</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis_RikardWellander.pdf">https://portal.research.lu.se/files/3311362/4858082.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7600533</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Combustion Physics, Department of Physics, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Post injection</topic> <topic>Structured illumination</topic> <topic>Mie scattering</topic> <topic>Dense sprays</topic> <topic>Extinction coefficient</topic> <topic>Signal attenuation</topic> <topic>Laser extinction</topic> <topic>Multiple scattering</topic> <topic>Scattering measurements</topic> <topic>Planar laser induced fluorescence</topic> <topic>Time resolved</topic> <topic>Imaging through turbulent media</topic> <topic>Three-dimensional image acquisition</topic> <topic>Diesel particulate filter regeneration</topic> <topic>Wall impingent</topic> <topic>Biodiesel</topic> <topic>LII</topic> <topic>Large-bore gas Engine</topic> <topic>Pre-chamber ignition</topic> <topic>Fysicumarkivet A:2014:Wellander</topic> </subject> <subject authority="lup"> <topic>Atom and Molecular Physics and Optics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund reports on combustion physics</title> </titleInfo> <identifier type="issn">1102-8718</identifier> <identifier type="oldLupId">4858050</identifier> <part> <detail type="volume"> <number>177</number> </detail> <extent unit="pages"> <total>82</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-01-09T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>d4fceb27-c990-4ea8-9f03-92646e9e64ef</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:16+02:00</recordDateApproved> </recordInfo> </mods>

The purpose of this thesis was to study high-risk patients with multiple tumours including a CMM, high-risk families with the unique Swedish germline mutation in CDKN2A(113insArg), as well as study risk factors for CMM in women. &lt;br/&gt;&lt;br&gt; Methods: Tumours associated with CMM, in individuals/probands with four or more primary tumours including at least one CMM were genotyped. The probands were further sub-grouped according to subsequent cancers (Paper I). Possible similarities in tumour patterns were studied in their close relatives (Paper II*). Further, melanoma-prone families in southern Sweden with the 113insArg/CDKN2A mutation were phenotyped and genotyped (Paper III). Finally, a population-based cohort of originally 40.000 women was prospectively followed for 18 years regarding CMM after answering a questionnaire about CMM risk factors (Paper IV). &lt;br/&gt;&lt;br&gt; Results: Papers I-II: The mutation was overrepresented in probands with multiple CMM. Non-mutation probands presented e.g. Neural System Tumours (NSTs), adenocarcinomas and non-melanoma skin cancer (NMSC), which were also seen in their relatives. For the relatives an overall increased risk for cancer was seen. Paper III: Positive mutation status was associated with clinically atypical nevi (CAN), and CMM diagnosis with red hair colour and CAN. No CMM were diagnosed in non-mutation carriers. The overall total nevus count (median 12, IQR: 5-25) and rate of individuals affected by CAN (14%), were lower in these families than shown in previous, population-based, Swedish studies. No atypical mole syndrome (AMS) phenotype was seen. Paper IV: Family history and ≥1 nevus on the left arm were risk factors for CMM, irrespective of age of the participants. Younger women with a history of frequent sunbed use had an additionally increased risk for CMM. CMM on the trunk were associated with a family history of CMM, a high nevus number and the youngest age at diagnosis. &lt;br/&gt;&lt;br&gt; Conclusions: The 113insArg/CDKN2A mutation in these melanom-prone families is difficult to diagnose dermatologically, but the presence of CMM seems to be completely associated with the mutation. Hence, mutation carriers must be followed-up by dermatologists irrespective of phenotype. The population-based risks for CMM in southern Swedish women seem to be associated with a family history of CMM, a higher nevus number and, for younger women, the use of sunbeds. *Supplement.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2f01693f-4c95-4d8e-a1f5-3777a0e4ea35</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kari_Nielsen_ny_kappa_14_okt-1.pdf">https://portal.research.lu.se/files/3311482/1496206.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1803953</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>clinically atypical nevus</topic> <topic>nevus</topic> <topic>CDKN2A</topic> <topic>melanoma</topic> <topic>risk factors</topic> <topic>sunbed</topic> <topic>UVR</topic> </subject> <subject authority="lup"> <topic>Dermatology and Venereal Diseases</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-99-8</identifier> <identifier type="oldLupId">1494438</identifier> <part> <detail type="volume"> <number>2009:111</number> </detail> <extent unit="pages"> <total>120</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-11-20T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>2f01693f-4c95-4d8e-a1f5-3777a0e4ea35</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:17+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:05:11Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:17+02:00</recordDateApproved> </recordInfo> </mods>

HSCs give rise to red blood cells and white blood cells of myeloid and lymphoid lineages. The red blood cells are responsible for transporting oxygen throughout the body, while the myeloid and lymphoid cells are essentially required for immune responses. The HSCs reside in special niches in the bone marrow, and they are able to respond efficiently to external stresses and injury such as blood loss, infection, or damage caused by cytotoxic agents. Tumor cells and its associated microenvironment acquire multiple alterations which render the tumor cells to respond poorly to treatment. My thesis work is focused on several specific studies: (i) Study the function of Heme oxygenase 1 (HO-1), a key factor that regulates supply and transport of oxygen. HO-1 with its associated carbon monoxide (CO) mediates response of cells to DNA damages caused by irradiation or chemical genotoxic stress. (ii) Study the function of a key cell cycle regulatory gene, cyclin A1 in the regulation of proliferation, differentiation and migration of HSC, and the role of cyclin A1 and MMP9 in mediating response of the HSC and their adjacent BM microenvironment to genotoxic stress caused by irradiation. (iii) Study the role of the key cell cycle regulator CDK1 in mediating treatment response of leukemic cells to all-trans retinoic acid (ATRA). (iv) Characterize the cellular mechanisms of several anticancer drugs, and our newly developed anticancer drug candidate and its selective target PIP5K1a for treatment of metastatic cancer. We have used several sets of knockout mouse models in which HO-1 or cyclin A1 are deleted, either in germ lines or in specific tissues. In addition, we have used tumor xenograft mouse models in which human prostate cancer were implanted and grown in mice. We have also used normal and cancer specimens from patients with leukemia or prostate cancer. A panel of non-malignant and malignant cell lines has been applied in our in vitro functional studies. Our results have shown that mice lacking HO-1 gene has elevated H2AX, and loss of ATM expression and function. Induction of HO-1 expression reduces DNA damages and activates ATM-supported DNA repair via homologous recombination. We have shown that mice lacking cyclin A1 function has increased proliferation of HSC and migratory ability, and also impaired vascular niches. Mice without cyclin A1 function suffer early deaths after irradiation treatment compared to that of the wild-type mice. MMP9 may mediate the response of the BM to irradiation treatment. We further show that CDK1 plays an important role in mediating treatment response to ATRA-induced differentiation and cell cycle arrest. Finally, we show that our newly developed anticancer drug candidate ISA-2011B is a specific PIP5K1α inhibitor. ISA-2011B inhibits growth of invasive prostate cancer cells through its inhibitory effect on PIP5K1α/PI3K/AKT and AR/cell cycle pathways. Taken together, my work provides novel insights into stem cell regeneration and cancer therapy.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5e5fdce5-c9cf-4165-a6ef-f09b6f7ad0a4</url> </location> </relatedItem> <originInfo> <publisher>Experimental cancer research</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Hematopoietic stem cells</topic> <topic>genotoxic damage</topic> <topic>cell cycle</topic> <topic>leukemia</topic> <topic>heme oxygenase</topic> <topic>differentiation</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-009-8</identifier> <identifier type="oldLupId">4498772</identifier> <part> <detail type="volume"> <number>2014:80</number> </detail> <extent unit="pages"> <total>62</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-09T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>5e5fdce5-c9cf-4165-a6ef-f09b6f7ad0a4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:26+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:26+02:00</recordDateApproved> </recordInfo> </mods>

This is associated with inflammation of the liver tissue, resulting in severe liver injury. In this inflammatory process, leukocyte recruitment has emerged as a key feature. Therefore, the aim of this thesis was to analyze the detailed mechanisms behind intrahepatic leukocyte accumulation and its regulation in the pathophysiology of sepsis-associated or obstructive cholestasis and their impact on hepatocellular function and damage. For this purpose, cholestatic conditions were induced in C57BL/6 mice in the weIl established experimental models of LPS sepsis and obstructive cholestasis foIlowing bile duct ligation. Analyses included intravital fluorescence microscopy, histology, ELISA, RT-PCR, flow cytometry, determination of bilirubin and liver enzyme levels as well as measurement of bile flow and secretion. In doing so, it was found that P-selectin-mediated recruitment of leukocytes, but not the local production of pro-inflammatory mediators, is the primary cause of sepsis-associated cholestasis. Moreover, obstructive cholestasis is associated with P-selectin-mediated intrahepatic platelet accumulation, which crucially contributes to leukocyte recruitment and liver in jury. Besides, LFA-l mediates firm leukocyte adhesion in the liver microcirculation during obstructive cholestasis. Finally, inhibition of rhokinase attenuates cholestasis-induced CXC chemokine formation, leukocyte recruitment and hepatocellular damage in the liver. Thus, the results of this thesis clearly demonstrate that leukocyte recruitment in the liver plays a key role in the pathophysiology of cholestasis. Accordingly, it may be concluded that targeting leukocyte recruitment may be an effective strategy to preserve bile flow under septic conditions and to reduce cholestasis-induced liver injury.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0bce498c-3885-4551-a5e4-e6230d74b01b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Matthias_Laschke_forsattsblad_sid_1-2.pdf">https://portal.research.lu.se/files/3312115/1263861.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">830698</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Matthias_OMSL.pdf">https://portal.research.lu.se/files/3312117/1263857.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">139030</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Matthias_Laschke_HELA_A4.pdf">https://portal.research.lu.se/files/3312119/1263856.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3776231</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Leukocyte and Liver</topic> <topic>Inflammation</topic> <topic>Cholestasis</topic> <topic>Endothelium</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-85-9</identifier> <identifier type="oldLupId">1263750</identifier> <part> <detail type="volume"> <number>2008:132</number> </detail> <extent unit="pages"> <total>126</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-11-28T13:15:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

It is important to find these patients in an early state of the disease because then they can be treated and dialysis treatment can be avoided. To measure the glomerular filtration rate (GFR) an invasive technigue is used. In this thesis an equation to estimate GFR (eGFR) by drawing a blood sample and measure the concentration of cystatin C is presented. This equation is the first one working both for adults and children. To establish an equation working at all laboratories, primary and secondary reference preparations for cystatin C were developed. The secondary reference preparation will be used to establish an international calibrator, which can be used by the diagnostic companies to establish an uniform value of cystatin C.&lt;br/&gt;&lt;br&gt; Cystatin C has been proposed to be a marker of inflammation. In our study of patients, without any prior inflammation, who undergo elective surgery, the concentration of cystatin C was unaltered while an increase in the concentration of CRP was seen. This result shows that cystatin C is not a marker of inflammation.&lt;br/&gt;&lt;br&gt; Three different types of dialysis treatments (haemodialysis, haemofiltration, haemodiafiltration) were tested for their capacity to remove low molecular mass proteins (LMMP) and thus their potential for treatment of patients with kidney failure. The LMMP have been proposed to be uraemic toxins and must therefore be removed from the circulation. The result from our study showed that cystatin C, β2-microglobulin and β-trace protein can be used as markers for the efficiency of haemofiltration (HF) and haemodiafiltration (HDF). The elimination pattern of β-trace protein differs between HDF and HF and the free proteins might therefore be useful markers in the evaluation of different convective therapies.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/194deaf7-0695-44a7-880b-465fc953912c</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="VL.Avhandling_130821.pdf">https://portal.research.lu.se/files/3312151/3991208.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4669357</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Clinical Chemistry and Pharmacology, Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Medicinal Chemistry</topic> <topic>Pharmacology and Toxicology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-51-2</identifier> <identifier type="oldLupId">3991203</identifier> <part> <detail type="volume"> <number>2013:79</number> </detail> <extent unit="pages"> <total>62</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-09-13T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>194deaf7-0695-44a7-880b-465fc953912c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:28+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:28+02:00</recordDateApproved> </recordInfo> </mods>

The following overarching questions were asked: What aspects of narratives appear to be significant in the students’ reading trajectories? Which aspects of the narratives appear to be significant in the encounter with reading during the students’ teacher training?&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To place the present investigation in a wider context a social-cultural perspective on reading is used as a means to shed light on the empirical data of the thesis. The choice of methodology is based on an epistemology where life stories are viewed as something which can provide knowledge about people’s experience and perceptions. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; As an overarching result, the students’ stories show that reading is a relational process, which occurs with significant others. Significant others invite and confirm the individual to read in various contexts. The metaphor literary breast-feeding shows how interest is transmitted in a close relationship. It makes the child, pupil or student feel that he/she is a participant in different societies of readers. Artifacts are crucial to raise interest in texts. Such artifacts are used as tools to shape play, motivation and imagination. The student’s reading trajectories also clearly indicate that challenges and gaps exist between different contexts, and that these gaps challenge the individual and need to be bridged.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Avhandlingen belyser läsning och läsarbanor i ett livsperspektiv där fyra lärarstudenters berättelser om läsning från barndom till mötet med lärarutbildningen analyseras ur ett sociokulturellt perspektiv. Ur berättelserna om läsning i olika kontexter såsom familj, skola och lärarutbildning framträder ett perspektiv på läsning som en relationell process. I en relationell läsprocess visar sig viktiga andra, som bjuder in och bekräftar, vara de mest betydelsefulla grundförutsättningarna. Viktiga andra, d.v.s. de som är betydelsefulla och stöder läsprocessen, finns i alla de sammanhang som studenterna berättar om, från tidig läsning i barndomen till vuxenlivets läsning i olika läspraktiker. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Enligt studenternas läsarbanor finns flera olika läsarföreningar beroende på sammanhang. I berättelserna framkommer hur upplevelser av delaktighet i en läsarförening inte automatiskt överförs till en annan. I mötet med läsning i nya sammanhang uppstår större eller mindre glapp som utmanar och behöver överbryggas. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Att bli medveten om sin egen läsning i ett livsperspektiv kan innebära insikter i att läsning är en relationell process som sker i situerade praktiker kopplad till personliga, historiska, kulturella och sociala kontexter, vilket betyder att undervisning kring läsprocesser är en långt mera komplicerad process än att enbart lära ut hur text avkodas som isolerad färdighet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/96854fe5-cc65-488b-8a82-0b68f01a4025</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="2043_10875_AKS_muep.pdf">https://portal.research.lu.se/files/3313237/1748364.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2251571</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Malmö högskola</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>significant others</topic> <topic>reading trajectories</topic> <topic>reading as a relational process</topic> <topic>life stories</topic> <topic>societies of readers</topic> </subject> <subject authority="lup"> <topic>Educational Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Malmö Studies in Educational Sciences</title> </titleInfo> <identifier type="issn">1651-4513</identifier> <identifier type="isbn">978-91-86295-09-7</identifier> <identifier type="oldLupId">1748357</identifier> <part> <detail type="volume"> <number>No. 58</number> </detail> <extent unit="pages"> <total>236</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-01-14T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>96854fe5-cc65-488b-8a82-0b68f01a4025</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:50+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:50+02:00</recordDateApproved> </recordInfo> </mods>

Obesity is a major risk factor for several health issues such as type 2 diabetes (T2D) and cardiovascular disease. The adipose tissue is central in the maintenance of a normal energy homeostasis in the body for instance via regulating lipid storage and release. Besides being an important energy reserve, the adipose tissue is also an endocrine organ releasing a variety of molecules collectively called adipokines, able to affect many different tissues. During weight gain, an expanding adipose tissue may result in dysfunctional adipocytes with unbalanced lipid metabolism, dysregulated release of adipokines, infiltration of immune cells into the adipose tissue and subsequent low grade inflammation. This may result in both local and peripheral insulin resistance, hyperglycemia and the development of T2D. In this thesis we focus on several new players in adipocyte function and energy metabolism. For the first time we report that the phosphodiesterase (PDE) isoforms PDE9A and PDE10A are expressed in adipocytes. When investigating PDE activity in human obesity we found that total-, PDE3-, PDE4- and PDEn activity were downregulated in adipose tissue from obese patients. Inhibition of certain PDEs has previously been shown to result in a healthier adipocyte phenotype and we hypothesize that the reduced PDE activity in obesity is an attempt to create a healthier adipose tissue. We also report for the first time that the peptide hormone cocaine- and amphetamine-regulated transcript (CART) is expressed in adipocytes. When investigating the effects of CART on adipocyte metabolism we demonstrate that stimulating isolated adipocytes with CART results in several changes in adipocyte lipid- and glucose metabolism. In addition, adipocytes isolated from mice with β-cell-specific overexpression of CART, CARTtg mice, displayed altered adipocyte metabolism. Since CART can be found in blood and was found to be expressed in adipocytes, CART is a potential new adipokine able to affect neighboring cells as well as other tissues via the circulation. Regarding the effect of superantigen on adipocyte function, SEA was observed to bind to the cytokine receptor gp130 on primary rat adipocytes and activate downstream signaling through phosphorylation of STAT3. Incubation with SEA also resulted in reduced insulin sensitivity, in line with previously reported IL-6-induced adipocyte insulin resistance. This thesis has revealed many interesting data regarding new players in adipocyte metabolism and will hopefully lead to more research concerning the exact role of these players in adipocyte function as well as in obesity and T2D.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/61822cd5-1ec8-4ae9-b5cd-f5ff1fcb2f5e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Elin_Banke.pdf">https://portal.research.lu.se/files/3313353/4024413.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1858051</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-76-5</identifier> <identifier type="oldLupId">4024412</identifier> <part> <detail type="volume"> <number>2013:104</number> </detail> <extent unit="pages"> <total>80</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-10-04T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>61822cd5-1ec8-4ae9-b5cd-f5ff1fcb2f5e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:52+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:04:02Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:52+02:00</recordDateApproved> </recordInfo> </mods>

The aim of the study is to understand if and how scientific uncertainty affects the policy process. For that purpose, the development of climate change policy in Sweden is studied, from 1975 until 2007. The material studied consists of interviews with politicians, bureaucrats and scientists, newspaper articles and debate articles, as well as governmental and agency material. The theoretical framework developed and used in the dissertation builds on John Kingdon’s multiple streams framework as well as insights from Science and Technology Studies, relating to the production of knowledge and the relation between scientists and society. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The study shows that scientific uncertainty is only one among many factors that affect the policy process and that it has a limited influence. The area where scientific uncertainty, in the case studied, has had most influence is in the selection and formulation of policies. There policy makers have used a number of ways to make decisions in the face of uncertainty. These include reframing the issue so that uncertainties are no longer relevant, relying on the precautionary principle, requesting more research, and basing decisions on the judgment of scientists. The most common way of managing uncertainty has been to reframe the issue. In the case studied, scientific uncertainty has made scientists very influential as to how climate change has come to be understood as a political problem. Yet they have had a very limited influence over the formulation of climate policy.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Avhandlingen handlar om vetenskaplig osäkerhet i policyprocessen, det vill säga när vetenskaplig kunskap om en fråga saknas eller den existerande kunskapen är osäker. Studiens huvudsyfte är att förstå om och hur vetenskaplig osäkerhet påverkar policyprocessen. För att undersöka detta har utvecklingen av den svenska klimatpolitiken från 1975 fram till 2007 studerats. Materialet som undersöks består av intervjuer med politiker, tjänstemän och forskare, tidningsartiklar och debattartiklar, liksom riksdagstryck och rapporter från ämbetsverken. Det teoretiska ramverk som utvecklas och används i avhandlingen baseras på John Kingdons flödesramverk och forskning inom Science and Technology Studies, som behandlar produktionen av kunskap och relationen mellan forskare och samhället.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studien visar att vetenskaplig osäkerhet bara är en av många faktorer som påverkar utvecklingen i policyprocessen och att den inte är en av de mer framträdande. I det studerade fallet är det främst vad gäller val och utveckling av policyer som vetenskaplig osäkerhet har haft en påverkan. Politiska beslutsfattare har hanterat osäkerheten på ett antal olika sätt för att möjliggöra beslut trots den. De hanteringssätt som identifierats i avhandlingen är att en fråga omformuleras så att osäkerheterna inte blir relevanta, att försiktighetsprincipen åberopas, att mer forskning efterfrågas, och att beslut baseras på forskares bedömningar. Att frågan omformuleras har varit det vanligast förekommande sättet att hantera osäkerhet. I det studerade fallet har vetenskaplig osäkerhet inneburit att forskare fått ett stort inflytande över hur klimatfrågan ska förstås som politiskt problem, men däremot inte över hur den ska hanteras.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/17905f87-c25d-4786-9436-4e90e17f28c8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Knaggard_slutlig.pdf">https://portal.research.lu.se/files/3313639/1472546.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1288436</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Scientific uncertainty</topic> <topic>policy making</topic> <topic>Kingdon</topic> <topic>climate policy</topic> <topic>energy policy</topic> <topic>science and technology studies</topic> <topic>policy entrepreneur</topic> <topic>knowledge broker</topic> <topic>framing</topic> <topic>Sweden</topic> <topic>climate change</topic> <topic>policy process</topic> </subject> <subject authority="lup"> <topic>Political Science</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Political Studies</title> </titleInfo> <identifier type="issn">0460-0037</identifier> <identifier type="isbn">978-91-88306-75-3</identifier> <identifier type="isbn">91-88306-75-5</identifier> <identifier type="oldLupId">1472541</identifier> <part> <detail type="issue"> <number>156</number> </detail> <extent unit="pages"> <total>348</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-10-02T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>17905f87-c25d-4786-9436-4e90e17f28c8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:20:56+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:20:56+02:00</recordDateApproved> </recordInfo> </mods>

Causes have been divided into input, throughput, and output factors, of which the last appear to be the most influential. Unavailability of inpatient beds (so-called “access block,” or “hospital crowding”) impairs ED output and is associated with increased waiting times in the ED, especially for patients awaiting hospital admission (“boarding”). Access block has also been suspected to induce an admission-bias, causing only the sickest patients to be admitted to hospital when hospital beds are scarce. &lt;br/&gt;&lt;br&gt; The aim of this thesis was to evaluate whether access block affected the prioritization of the level of care in ED patients so that patients were less likely to be admitted to a hospital bed at times of access block than otherwise. Part V addressed whether more patients were triaged out of the ED at times of access block.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Methods: &lt;br/&gt;&lt;br&gt; In Part I, the proportion of hospital admissions among 118,668 visits to the ED, at a 420-bed emergency hospital in Region Skåne, Sweden, was compared across different levels of access block (measured as strata of in-hospital bed occupancy). Multivariate models were constructed to adjust for the effects of known confounders. In Part II, the appropriateness of ED discharges was addressed by comparing the proportion of unplanned 72h revisits to the ED across different levels of access block, for the 81,878 cases treated and released from the ED at index. In Part III, the outcomes evaluated in Parts I and II were addressed for 19,620 ED visits due to acute abdominal pain. Part IV was performed analogously to Part III, but for 12,223 ED visits due to chest pain. In Part V, the permeability of an ED front-end facility that triages patients of perceived low acuity out of the ED was compared across different levels of access block, for 37,129 visits to the facility.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Results: &lt;br/&gt;&lt;br&gt; In Part I, a negative association between access block and the probability of inpatient admission was observed (OR 0.67–0.81 at occupancy &amp;gt;105%, compared to at occupancy &amp;lt;95%), implying that patients were less likely to be admitted to the hospital at times of access block. Part II revealed no association between access block and the 72h revisit rate. The association detected in Part I remained for the study populations addressed in Parts III/IV. No association between access block and the 72h revisit rate was observed in patients with acute abdominal pain, but a negative association between the two was observed in patients with chest pain. ED length of stay in patients who were treated and released from the ED increased at times of access block, in Parts III/IV.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Conclusion: &lt;br/&gt;&lt;br&gt; ED patients were less likely to be admitted to a hospital bed at times of access block than otherwise, at the study site. The lack of an association with the 72h revisit rate could be interpreted as that the practice is safe, but since it fails to take into account rare, but fatal, outcomes such as mortality, future studies should address more granular patient outcomes and specific subgroups. Cost-effectiveness analysis could help to evaluate the viability of managing certain conditions in the ED as compared to in inpatient wards.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bakgrund:&lt;br/&gt;&lt;br&gt; Patientflödet genom en akutmottagning regleras framförallt av tre typer av faktorer. Dessa rör i tur och ordning inflödet-, genomflödet- och utflödet av patienter. Faktorer som reglerar inflödet rör efterfrågan på sjukvård (t.ex. samhällsdemografi och tillgång på primärvård), medan faktorer som reglerar genomflödet till största delen rör akutmottagningens interna processer (t.ex. sådana för diagnostik och behandling). Faktorer som reglerar utflödet från akutmottagningen innefattar tillgången på vårdplatser inom slutenvården och tillgången på uppföljande vård. Forskarsamhället är i princip enigt i att utflödet av patienter från akutmottagningen har särskilt stor inverkan på det fenomen som kallas trängselproblematik. Trängselproblematik kan definieras som en situation där stor efterfrågan på akutmottagningens resurser leder till att vårdbehovet hos en eller flera patienter inte kan tillgodoses. Bland faktorerna som reglerar utflödet från akutmottagningen intar tillgången på slutenvårdsplatser en särställning. Mycket akademisk nit har riktats mot det fenomen som i internationella sammanhang kallas ”boarding” och som innebär att patienter som ska läggas in på sjukhuset tvingas vänta kvar på akutmottagningen eftersom vårdplatser saknas. De väntande patienterna knyter upp resurser, som gör det svårare för akutmottagningen att möta behoven hos övriga patienter. Mindre väl studerat är huruvida brist på slutenvårdsplatser leder till att endast de sjukaste patienterna läggs in på sjukhus och att övriga i större utsträckning färdigbehandlas på akutmottagningen.&lt;br/&gt;&lt;br&gt; Avhandlingens övergripande syfte var att undersöka huruvida prioriteringen av vårdnivå bland akutmottagningens patienter påverkas av brist på slutenvårdsplatser (d.v.s. om färre patienter läggs in när sjukhuset är fullt). Det sista delarbetet fokuserade på huruvida fler patienter nekas att komma in på akutmottagningen när det råder vårdplatsbrist på sjukhuset, av den instans som kallas primärtriage och vars syfte är att sortera ut och hänvisa de patienter som upplevs för friska för att vara på akutmottagningen till annan vårdnivå (exempelvis till primärvården).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Metod:&lt;br/&gt;&lt;br&gt; Studien genomfördes på ett datamaterial hämtat från akutmottagningen vid Helsingborgs lasarett, under åren 2011-2013. Avhandlingens första del omfattade 118,668 akutbesök och fokuserade på huruvida vårdplatsbrist påverkade beslutet om att lägga in patienter från akutmottagningen på sjukhuset. Statistiska modeller konstruerades för att ta hänsyn till effekter av kända störfaktorer. Avhandlingens andra del fokuserade på huruvida vårdplatsbrist ledde till att patienter felaktigt skickades hem från akutmottagningen. Syftet var att utvärdera hypotesen om att brist på slutenvårdsplatser får personalen på akutmottagningen att ta risker i form av att skicka hem patienter som egentligen är för sjuka, och att kvaliteten på den vård som ges de patienter som färdigbehandlas på akutmottagningen således skulle vara sämre än den de annars skulle fått på sjukhuset. Hypotesen utvärderades med hjälp av effektmåttet oplanerade återbesök inom 72 timmar, som Socialstyrelsen upphöjt till nationell indikator år 2013. Avhandlingsdel tre och fyra fokuserade på samma utkomster som avhandlingsdel ett och två, men för patienter som sökte för de två vanligaste sökorsakerna på akutmottagningen: buksmärta respektive bröstsmärta. Avhandlingens femte och sista del fokuserade på prioriteringen av vårdnivå vid ankomsten till akutmottagningen. I avhandlingsdelen mättes associationen mellan tillgång på slutenvårdsplatser och sannolikheten för att en patient skulle triageras ut från akutmottagningen (exempelvis till primärvården) av den instans som kallas primärtriage.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Resultat:&lt;br/&gt;&lt;br&gt; Avhandlingens första del visade att patienter som sökte akutmottagningen då sjukhuset var fullt lades in i mindre utsträckning än patienter som sökte akutmottagningen annars. Detta även efter justering för flera störfaktorer (oddskvot 0.67–0.81 vid beläggningsgrad &amp;gt;105% jämfört med &amp;lt;95%). Avhandlingsdelar tre och fyra visade att effekten kvarstod även för de patienter som sökte för buksmärta respektive bröstsmärta. Avhandlingens andra del visade att de patienter som skickades hem från akutmottagningen då sjukhuset var fullt inte återsökte i större utsträckning än de som skickades hem annars. Avhandlingsdel tre visade att detsamma gällde för patienter som sökte med buksmärta. Patienter med bröstsmärta som skickades hem då sjukhuset var fullt återsökte dock i mindre utsträckning än de som skickades hem annars. I avhandlingens femte del sågs ingen ökad andel hänvisningar från primärtriage till annan vårdnivå då sjukhuset var fullt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Diskussion/slutsats:&lt;br/&gt;&lt;br&gt; Fynden visar att vårdplatsbrist inom slutenvården var associerad med att färre patienter lades in på sjukhuset. Detta gällde såväl för en osorterad patientpopulation som för patienter med buk- respektive bröstsmärta. Avsaknaden av en ökad andel oplanerade återbesök till akutmottagningen kan tolkas som att strategin inte medförde ökade medicinska risker, men eftersom indikatorn inte fångar alla aspekter av sjukdom bör framtida studier tillägnas beskrivningen av mer specifika utkomster för enskilda patientgrupper. En viktig sådan är dödlighet efter att ha blivit hemskickad från akutmottagningen. Framtida studier bör ta hänsyn till sådana utkomster tillsammans med förändringar i akutmottagningens resursutnyttjande, för att bättre kunna utvärdera vård på akutmottagningen som ett alternativ till vård på sjukhuset.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4577ecfc-5e98-4991-a8ee-e9e8dc36cf86</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Blom_hela_avh_g5.pdf">https://portal.research.lu.se/files/3320014/5426045.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4828891</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>emergency department overcrowding</topic> <topic>access block</topic> <topic>inpatient admission</topic> <topic>unplanned 72h revisits</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-152-1</identifier> <identifier type="oldLupId">5426041</identifier> <part> <detail type="volume"> <number>2015:73</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-06-12T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>4577ecfc-5e98-4991-a8ee-e9e8dc36cf86</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:04+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:04+02:00</recordDateApproved> </recordInfo> </mods>

In Paper I, we focused on the CD44 molecule that often is aberrantly expressed in breast cancer and is widely used as a marker for cancer stem cells. Several isoforms of the CD44 molecule were analyzed at the transcriptome level across breast tumors and the expression of individual isoforms was correlated to molecular subtypes, protein expression of clinical markers, and cancer stem cell (CSC) phenotypes in breast tumors and cell lines. The CD44S isoform was associated with expression of the CSC marker ALDH1 and the CSC phenotype CD44+/CD24- was correlated to alternatively spliced isoforms in tumors. The isoforms were differentially expressed in molecular subtypes and HER2 and EGFR positive tumors were associated to CD44S and CD44v8-10, respectively. In Paper II, by using targeted genomic re-sequencing we screened for somatic mutations in 1237 genes in a panel of basal-like breast cancer cell lines, both in coding and surrounding non-coding regions. In total, 658 high confidence SNVs and indels were detected and 315 of these were novel (not in COSMIC). A selection of the variants were validated with Sanger sequencing and, 123 of 130 high confidence variants were confirmed including 111 novel variants. The mutation frequency was higher in coding (CDS) compared to non-coding (non- CDS) regions and in particular G or C base replacements were higher in the CDS compared to non-CDS. The SNVs within the context of T[C]A/T[G]A and T[C]T/A[G]A were significantly more common in the CDS than in the non-CDS regions. Re-sequenced data was used to derive copy number estimations, which correlated well to SNP array data. In Paper III, the potential in using tumor-specific rearrangements present in circulating tumor DNA (ctDNA) to detect occult metastatic breast cancer was evaluated. In total, 14 eventual metastatic (EM) patients and 6 long-term disease free (DF) patients were investigated. We used whole-genome sequencing on the primary tumors to derive patient-specific rearrangements that were confirmed by PCR. Circulating tumor DNA levels across multiple plasma samples during the clinical course were analyzed by quantitative droplet digital PCR. Accurate post-surgical discrimination of EM patients (93%) from DM (100%) was achieved by ctDNA monitoring. The average lead-time to clinical detection of metastatic disease was 11 months (range 0-37 months). Moreover, the ctDNA level was a quantitative predictor for both recurrence (P=0.02) and death (P=0.04). We demonstrated that monitoring of ctDNA can be used for early detection of metastatic breast cancer and is a potential tool for optimization of adjuvant therapy and should be evaluated further in clinical studies.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/108ae96d-f1b9-4dcb-944c-9fc88be91e30</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Doctoral_Thesis_EleonorOlsson.pdf">https://portal.research.lu.se/files/3320128/5364612.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1808374</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Oncology and Pathology</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cancer stem cells</topic> <topic>RNA splicing</topic> <topic>breast cancer</topic> <topic>mutations</topic> <topic>circulating tumor DNA</topic> <topic>early detection of recurrent breast cancer</topic> <topic>sequencing</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-143-9</identifier> <identifier type="oldLupId">5364608</identifier> <part> <detail type="volume"> <number>2015:64</number> </detail> <extent unit="pages"> <total>109</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.biomedcentral.com/1471-2407/11/418</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-28T02:00:00+02:00</dateOther> <note type="additionalInfo">Appended papers Paper I: Olsson E, Honeth G, Bendahl PO, Saal LH, Gruvberger-Saal S, Ringnér M, Vallon-Christersson J, Jönsson G, Holm K, Lövgren K, Fernö M, Grabau D, Borg Å, Hegardt C.

The complement system, which is a part of the innate immune system, plays a central role in promoting the joint inflammation in these diseases. Potential activators of complement are certain extracellular matrix proteins that become exposed during cartilage degradation. Previous studies have revealed that several proteins from cartilage can activate or inhibit the complement system in vitro.&lt;br/&gt;&lt;br&gt; In the present work, we describe the interactions between the complement system and additional extracellular matrix proteins, with the aim to better understand the role of endogenous ligands in the inflammatory process in joint diseases. We also describe the interactions between complement proteins and cartilage explants that have been subjected to inflammation-induced degradation.&lt;br/&gt;&lt;br&gt; In paper I, we found that the G3 domain of aggrecan activates the classical pathway of complement. However, the activation of the terminal pathway is limited due to the simultaneous binding of factor H. Whether it activates complement when maintained in cartilage or when released into the synovial fluid remains to be elucidated.&lt;br/&gt;&lt;br&gt; In paper II and III, we found that both proline/arginine-rich end leucine-rich repeat protein (PRELP) and the domain NC4 of collagen type IX, inhibit complement by preventing the assembly of the membrane attack complex. Further, PRELP also inhibits the assembly of the alternative pathway C3 convertase, while NC4 enhances the cofactor activities of C4b-binding protein and factor H, in the factor I-mediated cleavage of C4b and C3b. NC4 and fragments of PRELP can be detected in the synovial fluid of rheumatoid arthritis patients. Located in the synovial fluid or exposed on the cartilage surface, they might be important for limiting the complement activation, induced by other extracellular matrix proteins or other potential triggers.&lt;br/&gt;&lt;br&gt; In Paper IV, we found that both the classical and the alternative pathways are activated on the surface of degraded cartilage explants, while components released from cartilage might have a weak, somewhat delayed, opposing role by inhibiting complement. The main activation seems to occur after the major loss of aggrecan from cartilage.&lt;br/&gt;&lt;br&gt; In sum, several proteins of the extracellular matrix, as well as degraded cartilage have the potential to interact with the complement system, and may regulate the inflammatory processes in joint diseases.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Människans immunförsvar ska hjälpa oss att bekämpa infektioner från bakterier och virus. Immunförsvaret kan delas in i två delar; det adaptiva immunförsvaret, som utvecklas hela tiden under livets gång, samt det medfödda immunförsvaret.&lt;br/&gt;&lt;br&gt; De flesta känner kanske till att kroppen kan utveckla antikroppar mot bakterier. Antikroppar känner igen och markerar ut främmande strukturer på till exempel en bakterie, så att immunceller kan känna igen och oskadliggöra dem. Dock tar det några dagar för kroppen att bygga upp detta försvar, eftersom stora mängder antikroppar måste produceras och förfinas för att effektivt kunna markera en bakterie. Fördelen med specialiserade antikroppar är att kroppen minns hur de ser ut, och därför kan producera dem snabbare nästa gång kroppen attackeras av en liknande bakterie. Flera typer av immunceller är inblandade i denna utvecklingsprocess, och utgör en del av det adaptiva immunförsvaret.&lt;br/&gt;&lt;br&gt; Det medfödda immunförsvaret är minst lika viktigt eftersom det hela tiden är redo att aktiveras och gå till omedelbar attack när en invaderande bakterie upptäcks. Till det medfödda immunförsvaret hör flera olika sorters immunceller som bland annat har till uppgift att äta upp och oskadliggöra bakterier eller virusinfekterade celler. Hit hör även komplementsystemet, som bland annat känner igen generella strukturer på bakterier och döende celler, och som varnar resten av immunförsvaret att här är fara och färde.&lt;br/&gt;&lt;br&gt; Komplementsystemet består av bortåt 40 olika proteiner som cirkulerar runt i kroppen eller finns bundet på ytan av kroppens celler. En del av komplementproteinerna är ordnade i en kaskad, och när komplementsystemet utsätts för aktiverande stimuli (t.ex. en bakterie) startas en kedjereaktion där en komponent i övre delen av kaskaden klyver och aktiverar nästa komponent i kaskaden. Det resulterar i att flertalet olika klyvningsprodukter bildas som har olika biologiska funktioner. En del lockar till sig immunceller till platsen där aktiveringen har skett och startar olika inflammatoriska reaktioner, medan andra märker in den komponent som orsakat aktiveringen med markörer som underlättar att den blir bortstädad. Proteiner i slutet av kaskaden kan även skapa porer i bakteriers cellmembran så att de går sönder.&lt;br/&gt;&lt;br&gt; Komplementsystemet kan aktiveras genom tre olika vägar beroende på vilket stimuli systemet stöter på. Den klassiska vägen aktiveras av att proteinet C1q känner igen och binder till antikroppar, döende celler, en del typer av bakterier&lt;br/&gt;&lt;br&gt; 45&lt;br/&gt;&lt;br&gt; eller vissa kroppsegna proteiner. Lektinvägen aktiveras när proteinet MBL exempelvis binder till vissa typer av sockerkedjor som bara finns på bakterier. Den alternativa vägen aktiveras spontant i låg grad hela tiden på alla ytor, men tillåts bara ge en stark respons på främmande ytor. Komplementaktiveringen hålls under normala fall hela tiden under noga kontroll av komplementhämmare, så att en lagom respons tillåts.&lt;br/&gt;&lt;br&gt; Det finns ett välutvecklat samspel och kommunikation mellan komplementsystemet och olika sorters immunceller för att ge ett så effektivt och balanserat försvar som möjligt. Responsen gentemot ett yttre hot, som en bakterie, ska inte vara densamma som mot skadade kroppsegna strukturer, även om många av de involverade cellerna och molekylära komponenterna är densamma. Är det obalans i responsen gentemot kroppsegna strukturer kan det bland annat uppstå överdriven inflammation, cellulära förändringar och skador. Obalans i immunförsvaret ligger bakom flera olika sjukdomar, såsom reumatoid artrit (ledgångsreumatism), osteoartrit (artros) och systemisk lupus erythematosus. Komplementsystemets roll i just reumatoid artrit och osteoartrit diskuteras i denna avhandling.&lt;br/&gt;&lt;br&gt; Hos patienter med ledsjukdomarna reumatoid artrit och osteoartrit sker en gradvis försämring av de drabbade ledernas funktion, vilket orsakar stor smärta och begränsningar i rörelseförmågan. På benytorna i en led finns brosk som har som uppgift att underlätta benens rörelser mot varandra och fungera som stötdämpare. I de här sjukdomarna sker en onormal nedbrytning av brosk och ben i de drabbade lederna, och man ser även tydliga tecken på inflammation framförallt i ledgångsreumatism. I flertalet studier har man visat att komplementsystemet är extra aktiverat i lederna hos dessa patienter, jämfört med hos friska personer. Man tror att komplementaktiveringen bidrar starkt till det inflammatoriska tillstånd man ser hos de här patienterna.&lt;br/&gt;&lt;br&gt; En mycket spännande upptäckt som har gjorts är att proteiner som vanligtvis bygger upp strukturerna i brosket även kan ha en förmåga att påverka komplementsystemet och därmed immunförsvarets aktivitet. I tidigare studier har man visat att flera olika sorters protein från brosk antingen kan aktivera eller hämma komplementsystemet. I artikel I-III studerade vi hur ytterligare tre broskproteiner påverkar komplementsystemet. Vi såg att en del av den stora molekylen aggrecan kunde aktivera den klassiska vägen av komplement, medan PRELP och NC4 kunde förhindra att komplementproteiner formade den porstruktur som kan skada celler.&lt;br/&gt;&lt;br&gt; Frågan är varför brosket inte alltid stimulerar komplementsystemet och ger inflammation. En anledning skulle kunna vara att molekylerna i brosket inte är tillgängliga förrän en viss brosknedbrytning redan har påbörjats. Brosknedbrytningen kan göra så att nya strukturer exponeras hos proteinerna vid ytan av brosket, till vilka komplementproteiner från ledvätskan kan binda in. I&lt;br/&gt;&lt;br&gt; 46&lt;br/&gt;&lt;br&gt; artikel IV visar vi att en skadad broskyta aktiverar komplementsystemet, medan en oskadad yta inte gör det. En tidig hypotes har varit att proteinfragment som frigörs från brosket och hamnar i ledvätskan även där kan stimulera komplement. I vår studie kan vi dock inte visa att de här fragmenten aktiverar komplement. Snarare ser vi en tendens till att fragmenten har en motsatt effekt och istället hämmar komplement. Kanske kan denna effekt delvis motverka den aktiverande effekt som vi ser att den skadade broskytan har. Man kan tänka sig att en viss komplementaktivering på ytan av skadat brosk (om skadan är liten) kan vara fördelaktig, eftersom det bidrar till att locka till sig immunceller som kan städa bort skadade proteiner. Men blir det en okontrollerad, överdriven aktivering skapas det en inflammatorisk miljö som är skadlig för vävnaderna i leden och som eldar på brosknedbrytningen ytterligare.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/114a6984-466b-4e4f-9b45-e5478e627874</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Camilla_avh_20160205.pdf">https://portal.research.lu.se/files/3320359/8599536.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1106855</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Division of Medical Protein Chemistry, Department of Translational Medicine, Lund University, Faculty of Medicine,</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Complement system</topic> <topic>rheumatoid arthritis</topic> <topic>osteoarthritis</topic> <topic>extracellular matrix</topic> <topic>cartilage degradation</topic> <topic>mass spectrometry</topic> </subject> <subject authority="lup"> <topic>Biomedical Laboratory Science/Technology</topic> <topic>Immunology in the Medical Area (including Cell and Immunotherapy)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-246-7</identifier> <identifier type="oldLupId">8599023</identifier> <part> <detail type="volume"> <number>2016:20</number> </detail> <extent unit="pages"> <total>74</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-02-26T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>114a6984-466b-4e4f-9b45-e5478e627874</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:09+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:09+02:00</recordDateApproved> </recordInfo> </mods>

These bacteria can give rise to numerous infections such as septicaemia and urinary tract infections. It is important to combat these infections with effective antibiotics, because many of them are associated with high mortality rates if left untreated. In infections with ESBL-producing bacteria in low-endemic countries, the initial empirical antibiotic treatment will probably be ineffective and thus lead to higher mortality if the infection is severe. Therefore, it is important to identify patients that are at risk of such infections and also to avoid spreading the bacteria. &lt;br/&gt;&lt;br&gt; The present research aimed to determine the cause of the rapid increase in ESBL-producing Enterobacteriaceae in patients in our hospital and our community. Our initial results clearly demonstrated that huge numbers of ESBL-positive faecal samples were collected from patients who contracted travellers’ diarrhoea after visiting high-risk areas. Twenty-four percent of patients with travellers’ diarrhoea were colonized with ESBL-producing. Strains of ESBL-producing E. coli were especially common in patients who visited Egypt (50%) and India (78.5%). Follow-up of the same cohort (Paper III) regarding duration of colonization with ESBL-producing E. coli showed that 10/41 patients were positive for such bacteria after 3–8 months, although four of the 10 carried a different strain than the one initially identified. After three years, 4/41 patients still harboured ESBL-producing E. coli, although one of those four carried two new strains. This immense impact of travelling on faecal carriage is noteworthy, especially considering that global travel is still increasing at the rate of almost a billion passengers annually.&lt;br/&gt;&lt;br&gt; The total prevalence of faecal carriage of ESBL-producing bacteria in the study population (Paper II) was 1.9% in 2008 and 5.0% in 2010. The prevalence increased from 1.8% to 6.8% among hospitalized participants and from 2.1% to 3.0% among patients in primary care. These observations distinctly demonstrate that ESBL-producing bacteria represent an emerging problem in the community, particularly in hospitals. The findings also concur with our results suggesting that hospitalization longer than one month, especially in a surgical ward, constitutes a risk for infection with ESBL-producing E. coli (Paper V). Despite lack of evidence of patient-to-patient transmission in our hospital, the described findings highlight the need for good infection control and, when indicated, narrow and rational antibiotic therapy to lower the selective pressure. &lt;br/&gt;&lt;br&gt; We are among the first to study possible occurrence of ESBL-producing Enterobacteriaceae in food in Sweden (Paper V). We found no such bacteria in either domestic or imported foods. However, significantly more Enterobacteriaceae were detected in lettuce than in air-dried/cured meat products.&lt;br/&gt;&lt;br&gt; The rapid increase and spread of the carbapenem-resistant NDM-1-producing Enterobacteriaceae, especially in India and the Middle East, plainly illustrates that the current antibiotic situation is very precarious, and that it is essential to continue development of new antibiotics. The most important factor in this context is probably the need for establishing well-functioning sewage systems in large parts of the world (primarily Asia and Africa). Ensuring that people in developing countries have access to fresh food and water without the risk of faecal contamination would solve many problems.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bland infektionssjukdomarna är Enterobacteriaceae den viktigaste gruppen av bakterier. Den kan orsaka ett flertal olika infektioner så som blodförgiftning, urinvägsinfektion, hjärnhinneinflammation, bukhinneinflammation, gallvägsinfektioner, lunginflammation och diarrésjukdomar. Den vanligaste orsaken till blodförgiftning är bakterier som har kommit in i blodet från urinvägarna (så kallad urosepsis) och de orsakas vanligen av bakterier från gruppen Enterobacteriaceae (t.ex. E.coli och K.pneumoniae). Det är viktigt att behandla dessa infektioner med effektiv antibiotika för ett flertal av dessa infektioner är dödliga om de inte behandlas.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det är mycket troligt att både de flesta antibiotika och de flesta resistensmekanismer har utvecklats under miljontals år som en följd av konkurrensen mellan mikroorganismer i jord, växter och i haven. Antibiotika och olika resistensmekanismer är en del av den ständiga kampen och konkurrensen mellan arter för att kunna dominera en ekologisk nisch. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De mest använda och effektiva antibiotika är sprunget ur Alexander Flemings upptäckt penicillin och kallas för betalaktamantibiotika. Utanför Cagliari i Italien isolerade Brotzu fram en svamp, Cephalosporium acremonium, från havsvatten nära ett avlopp 1945 när han studerade ett utbrott av tyfus. Ur denna svamp kunde sedan Chain och Abraham i England extrahera fram den första cefalosporinantibiotika, cefalosporin C. Cefalosporinerna har visat sig vara mycket effektiva i behandlingen av många olika sorters infektioner allt från livshotande infektioner som hjärnhinneinflammationer och blodförgiftningar till lindriga urinvägsinfektioner och övre luftvägsinfektioner orsakade av gramnegativa eller grampositiva bakterier. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I början av 1980 talet kom den tredje generationens cefalosporiner som sågs som ett genombrott i kampen mot betalaktamaserna (enzymer som bryter ned antibiotika). Redan 1983 kom tyvärr den första rapporten om enzymer som kunde hydrolysera (bryta ned) även dessa antibiotika. Enzymerna var genetiskt mycket snarlika (skiljer 1-4 mutationer) några av de betalaktamaser som hade upptäckts på 1960-talet ( SHV-1, TEM-1 och 2) och benämndes Extended-Spectrum beta-lactamases (ESBL). ESBL definieras vanligen som betalaktamaser som kan hydrolysera första, andra och tredje generationens cefalosporiner, penicilliner samt aztreonam, men som kan inhiberas av klavulansyra in vitro. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Frekvensen av Enterobacteriaceae med ESBL har ökat kraftigt under de senaste åren. Från att 2004 varit ett relativt okänt begrepp har patientfallen med ESBL-producerande Enterobacteriaceae blivit allt fler. Hos E.coli och K.pneumoniae som förvärvat ESBL finner man framförallt enzymerna ur klassen CTX-M (CefoTaXimase München). Endast i Skåne har vi över tusen vårddygn varje år p.g.a. ESBL producerande-bakterier. Många av ESBL-producerande Enterobacteriaceae är även resistenta mot andra antibiotika såsom kinoloner och aminoglykosider. Detta leder till stora behandlingssvårigheter. Konsekvenserna av den ökade resistensen orsakar att patienter får felaktig antibiotikabehandling, med ökad mortalitet som följd och även ökade kostnader samt behov av fler isoleringsrum. Det enda effektiva empiriska preparatet som har effekt på ESBL-producerande Enterobacteriaceae är karbapenemer. Ökad användning av karbapenemer kommer med all säkerhet att leda till ökad karbapenemresistens hos andra bakterier (exempelvis Pseudomonas aeruginosa). Man har även de senaste åren noterat en spridning sista året av karbapenemresistenta Enterobacteriaceae från Indien.Därför är det viktigt att klargöra vilka riskfaktorer som finns dels för att man bättre skall kunna ge rätt behandling från början, dels för att förstå epidemiologin av betalaktamaser. Därigenom ökar chanserna att kunna förutspå hur nya betalaktamaser (som exempelvis NDM-1) kan komma att spridas globalt.&lt;br/&gt;&lt;br&gt; Antibiotikaförskrivningen i Sverige är låg med internationella mått mätt. Däremot har inte&lt;br/&gt;&lt;br&gt; antibiotikaföreskrivning i andra delar av världen (t ex södra delen av Europa och Sydostasien) varit lika välreglerad. Där har man sedan flera år haft en mer uttalad antibiotikaresistens och också ökad förekomst av Enterobacteriaceae med ESBL. Man har kunnat visa i studier att upp till 60 % av E.coli och K.pneumoniae isolaten har haft ESBL i Indien och Mellanöstern.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I två av våra studier har vi tittat på prevalensen av ESBL-producerande tarmbakterier hos patienter som har sökt med diarréer efter utlandsresor (turistdiarréer). Vi fann överraskande höga siffror hos de patienter som hade vistats utanför Europa (36 %) jämfört de som vistats inom Europa (3%). Värst drabbade blev de som hade åkt till Mellanöstern (50 %) och Indien (11 av 14 patienter). Vi följde den här gruppen och fann att frekvensen med tarmbakterier med ESBL avtog med tiden, till ca 25 % som var positiva efter 3-8 månader och till ca 10 % efter tre år. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I vår andra studie undersökte vi hur vanliga ESBL-producerande bakterier är på olika sjukhusavdelningar jämfört med hur vanliga de är ute i samhället. Hos relativt friska personer från vårdcentraler mellan år 2008 till 2010. Vi tog faecesprover på 427 personer. Vi fann att prevalensen 2008 var 2,1 % (2/96) hos de relativt friska individerna och 1,8 % (2/117) hos sjukhuspatienterna. År 2010 hade antalet personer med ESBL-producerande bakterier ökat till 3 % (3/100) bland de relativt friska invånarna och till 6,8 % (8/118) bland sjukhuspatienterna. Detta var en snabbare ökning än vad vi hade förväntat även om den inte var signifikant.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att ta reda på om importerade livsmedel från Medelhavsområdet kunde utgöra en reservoar och en spridningskälla för ESBL-producerande bakterier så tog vi 419 prover på olika livsmedelsprodukter varav 385 var från Medelhavsområdet och 34 av inhemskt ursprung. Vi analyserade även 99 E.coli stammar tagna från svenskt nötkött samt 94 E.coli-stammar från ett svenskt livsmedelstestlaboratorium. Vi hittade Enterobacteriaceae i 349 av 419 livsmedelsprover. I de flesta av dessa prover växte även gramnegativa miljöbakterier. Vi hittade inga ESBL-producerande bakterier, däremot fann vi som ett bifynd att lufttorkade livsmedel innehöll signifikant färre Enterobacteriacae än sallader och grönsaker. Denna studie stödjer inte teorin att importerat livsmedel bidrar till spridningen av ESBL-producerande bakterier.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I vår sista studie tog vi två åldersmatchade grupper där ena gruppen hade konstaterad ESBL-producerande E.coli och den andra gruppen hade E.coli utan ESBL-produktion från odlingar av urin eller blod. Vi fann 109 patienter i vardera grupp under januari till oktober 2008. Ungefär lika många svarade på enkäten i båda grupperna (kring 50 %). De med ESBL-producerande E.coli hade signifikant oftare (p &amp;lt;0.05) rest i riskområden (Asien och Mellanöstern). Vi fann också att de som hade E.coli med ESBL-produktion signifikant oftare (p&amp;lt;0,04) hade vistats på sjukhus senaste året och framför allt vistats på sjukhus under längre tid, &amp;gt; 1 månad (p=0.01), jämfört med kontrollgruppen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att tackla de problem som den ökade förekomsten av ESBL-producerande tarmbakterier innebär måste man säkra god hygien på sjukhus och vårdinrättningar. Dessutom måste man bara förskriva antibiotika till dem som behöver det. Vidare måste vid misstanke om att en svårt sjuk patient är infekterad av en ESBL-producerande tarmbakterie ge antibiotika täckning för denna bakterie så att patienten inte löper ökad risk att dö. De patienter som bör få bredare antibiotikabehandling är de patienter med känt ESBL-bärarskap, en resehistorik (åtminstone sista halvåret) till Asien, Afrika eller till Mellanöstern och de som har vårdats på sjukhus i mer än en månads tid, särskilt om de har fått flera antibiotika behandlingar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Då karbapenemer är vår sista effektiva antibiotika mot dessa resistenta bakterier är den mycket snabba spridningen och ökningen av karbapenemresistenta tarmbakterier (Enterobacteriaceae med NDM-1) från de befolkningstäta områdena på den Indiska subkontinenten djupt oroväckande. Konsekvensen av spridningen kommer att leda till en betydande mortalitetsökning i svåra infektioner!&lt;br/&gt;&lt;br&gt; Lösningen på de resistenta bakterierna är inte bara att framställa nya antibiotika. Man måste också komma åt roten till det onda annars kommer vi att förlora nästa antibiotikageneration också. Därför måste man ordna så att utvecklingsländer och länder i Asien och Afrika får tillgång till friskt vatten och livsmedel samt välfungerande avloppssystem.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/368c861e-ee69-4fa6-be31-f2aca9b4e258</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa_klar_28_aug_1_.pdf">https://portal.research.lu.se/files/3320403/3045665.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1009825</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Extended-spectrum beta-lactamase</topic> <topic>ESBL</topic> <topic>risk factors</topic> <topic>resistant bacteria</topic> <topic>E. coli</topic> <topic>Enterobacteriaceae</topic> <topic>antibiotics</topic> <topic>food</topic> </subject> <subject authority="lup"> <topic>Infectious Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-28-9</identifier> <identifier type="oldLupId">3045564</identifier> <part> <detail type="volume"> <number>2012:65</number> </detail> <extent unit="pages"> <total>85</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-09-21T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>368c861e-ee69-4fa6-be31-f2aca9b4e258</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:10+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:10+02:00</recordDateApproved> </recordInfo> </mods>

Upon renal injury the kidney has an endogenous ability to repair damaged tubules and restore kidney function, provided that the patient receives adequate supportive care in time. The molecular basis for this regeneration process is still not fully elucidated and the cellular origin for regeneration is extensively debated. Kidney cancer is characterized by vague clinical symptoms and pronounced resistance to common cancer therapies, like chemotherapy and radiation. Consequently, nearly 25% of patients present with spread disease already at diagnosis. For these patients a dismal prognosis awaits, with a 5-year survival rate of less than 10%. Thus, there is a desperate need for development of novel targeted therapies and diagnostic methods.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis we describe a new cell type intermingled between the proximal tubular cells of the nephron in normal human kidney. These cells share marker expression with regenerating tubules and display stem cell-like abilities as well as distinct morphological properties, such as low mitochondrial content and extensive structural and anchorage protein expression. By developing a novel human explant model of ATN ex vivo we also show that these cells are more resilient to injury. These cells were detected in normal chimpanzee and pig kidney, but not in mice, not even after induced renal injury. Additionally, the transcriptional profile of these cells is similar to that of papillary renal cell carcinoma (pRCC), and correlate to worse prognosis in clear cell RCC (ccRCC). These results indicate that these cells survive renal insults to a higher extent than bulk proximal tubule cells, and become activated to repopulate the tubule, but also suggest that pRCC might originate from oncogenic transformation of these cells.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the second part of this thesis we show that the dopamine transporter SLC6A3 is highly expressed and functional in ccRCC, while only being expressed at very minute levels in normal kidney and other cancer forms. Additionally, we show that the SLC6A3 expression is affected by hypoxia inducible factor 2 alpha (HIF-2α), an important protein in the cellular oxygen sensing system, which is ubiquitously expressed in the constantly pseudohypoxic ccRCC tumors. We further demonstrate that hypoxia induces SLC6A3 expression in normal kidney cells, but not in cells from other normal tissues like breast or vessels. These results show that SLC6A3 is a highly specific biomarker for ccRCC and that the endogenous features of this dopamine transporter may be utilized for the development of novel treatment modalities in ccRCC.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/70507f3d-4219-4084-895a-7aed4ad705e3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="106962_4_G5_Jennifer_H_KAPPAN.pdf">https://portal.research.lu.se/files/3320550/8840691.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4382671</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-262-7</identifier> <identifier type="oldLupId">8840623</identifier> <part> <detail type="volume"> <number>2016:36</number> </detail> <extent unit="pages"> <total>88</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ejh.it/index.php/ejh/article/view/2567</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-04-01T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>70507f3d-4219-4084-895a-7aed4ad705e3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:12+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:12+02:00</recordDateApproved> </recordInfo> </mods>

Patients who are eligibly for endocrine treatment are selected by the tumour-specific expression of oestrogen receptor (ER) and approximately 70 % of all breast cancer patients are classified as ER positive. However, resistance to tamoxifen is common and several patients will experience tumour relapse and might also die from their disease. This stresses the need for identifying treatment predictive factors that can guide clinicians during treatment decisions. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We have identified biomarkers that were associated with tamoxifen response in a material of premenopausal breast tumours. One of the markers is Pak1, a serine/threonine protein kinase, of which high expression and particular nuclear localisation was associated with poor tamoxifen response. Two other biomarkers are different ER phosphorylations at serine 305 and serine 118; ERS305-P and ERS118-P, respectively. Tumours that were positive for ERS305 were associated with poor tamoxifen response while tumours with high expression of ERS-118 were associated with a good response. Furthermore, we have studied associations between the activated kinases responsible for these ER phosphorylations and tamoxifen response. Our observations led us to conclude that ERS118-P and ERS305-P are better tamoxifen predictive factors than their respective phosphorylating kinases, and possibly, using a combination of the phosphorylations might be even more valuable in predicting the response.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In addition, we have identified Pak1 as a regulator of the hypoxic response in breast cancer cells. More specifically, we have observed Pak1-mediated phosphorylation of the hypoxia inducible transcription factor 1α (HIF-1α). Silencing of Pak1 led to decreased HIF-1α levels and less transcriptional activity, suggesting that Pak1 phosphorylation stabilises HIF-1α and thereby increases HIF-1α’s ability to induce gene expression during tumour hypoxia.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/754755e0-7849-4aff-971e-9746ea9e7868</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Caroline_W_kappan.pdf">https://portal.research.lu.se/files/3320907/1369455.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1778994</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cancer and Oncology</topic> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-26-4</identifier> <identifier type="oldLupId">1369453</identifier> <part> <detail type="volume"> <number>2009:39</number> </detail> <extent unit="pages"> <total>121</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-08T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>754755e0-7849-4aff-971e-9746ea9e7868</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:17+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:17+02:00</recordDateApproved> </recordInfo> </mods>

Method: Patients diagnosed with severe depression/melancholia between 1956 and 1969 were interviewed 37- 53 years after index admission. Seventy-five telephone interviews were held and medical records were read in many cases. Long-term course of depression was evaluated by cluster analysis. Suicide attempts were related to the depressive course. Among those interviewed, 13 who made one or more suicide attempts were in 2013 asked to attend a qualitative interview. Semi-structured interviews were held, using an interview guide and analysed according to grounded theory technique. Result: There was a short-term course, with or without recurrence, or a chronic course with or without late remission. Heredity for depression was significantly related to a chronic course, with or without late improvement. Twenty-nine subjects had attempted suicide, of whom 13 had made repeated attempts. The risk of attempting suicide decreased by 10% for every decade which depression occurred. Suicide attempts were made early in the course of depression, and there was a longer total time of depression after suicide attempts than before. Three categories where identified after a suicide attempt: coming under professional care, experiencing a relief in the personal situation and making a decision to continue to live. From these a core-category emerged labelled regaining control and taking care of oneself. Conclusion: Both long-term improvement and late recurrences are possible after a chronic course of severe depression. Our results also indicate that recovery from depression is not a precondition for ending suicidal behavior. Adding some kind of psychosocial treatment to initial somatic treatment seems important.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/365a7e1f-74de-44af-a581-8bf4f2d63d29</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="E-spik_Lisa_Crona.pdf">https://portal.research.lu.se/files/3321017/8229313.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2305558</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>life-chart</topic> <topic>qualitative</topic> <topic>suicide attempt</topic> <topic>psychotic depression</topic> <topic>long-term melancholia</topic> <topic>depression</topic> </subject> <subject authority="lup"> <topic>Psychiatry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-220-7</identifier> <identifier type="oldLupId">8229303</identifier> <part> <detail type="volume"> <number>2015:140</number> </detail> <extent unit="pages"> <total>83</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-12-16T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>365a7e1f-74de-44af-a581-8bf4f2d63d29</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:18+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:18+02:00</recordDateApproved> </recordInfo> </mods>

In order to have effect of future disease-modifying therapies for AD, the disease must be identified early, before the patients have developed dementia. Many patients with Mild Cognitive Impairment (MCI) have prodromal AD, but other causes for the syndrome are common. No diagnostic method can identify AD in patients with MCI with sufficient accuracy.&lt;br/&gt;&lt;br&gt; Aim: Evaluation of biomarkers in cerebrospinal fluid (CSF) and plasma for identifying prodromal AD in patients with MCI.&lt;br/&gt;&lt;br&gt; Settings: At baseline 137 subjects with MCI and successful lumbar puncture were included. CSF from baseline was analyzed for phosphorylated tau (P-tau), total tau (T- tau) and amyloidβ1-42 (Aβ42). Furthermore, the levels of soluble receptors for Tumor Necrosis Factor-α (sTNFR) 1 and 2, as well as soluble CD40 (sCD40) and the CD40 ligand were analyzed. The latter biomarkers reflect inflammation.&lt;br/&gt;&lt;br&gt; Results: After the first follow-up of around 5 years, 57 patients had developed AD dementia. The levels of T-tau, P-tau and Aβ42 could with high accuracy identify patients with prodromal AD. After the second follow-up was finished, approximately 9 years from baseline, 72 patients had developed AD dementia. The positive and negative predictive values of the Aβ42/ P-tau ratio after this follow-up were around 90%. The Aβ42 levels were pathological already 10 years before progression to dementia. Moreover, Tau and Aβ42 were quite stable over time in patients with AD dementia. The levels of TNFR 1 and 2 both in CSF and plasma and sCD40 in plasma were elevated in the MCI patients with AD 5 years before progression to dementia.&lt;br/&gt;&lt;br&gt; Conclusion: CSF biomarkers can identify subjects with prodromal AD. Inflammation is an early feature of AD. These results have an impact on the diagnostic work-up of patients with MCI, as well as the development of AD therapies.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Alzheimers sjukdom (eng. Alzheimer’s disease, AD) är den vanligaste orsaken till de- mens. Demens innebär en permanent sänkning av intellektuella förmågor som påverkar individen påtagligt i vardagen. Förekomsten av demenssjukdomar ökar betydligt efter 65 års ålder. AD är en långsamt progredierande sjukdom, som oftast börjar med försämrat närminne. Redan idag är AD en betydande orsak till nedsatt livskvalitet, lidande och förtida död i världen. I och med en åldrande befolkning kommer tillståndet att bli än vanligare i framtiden.&lt;br/&gt;&lt;br&gt; Forskningen kring förhoppningsvis botande behandlingar mot AD är intensiv. Tyvärr har inte några av de behandlingar som tagits fram visat sig stoppa eller bromsa sjukdomen. Dessa studier har ofta gjorts på patienter med AD som redan utvecklat de- mens. Troligen börjar den sjukdomsframkallande processen vid AD flera decennier innan personen fått några symtom och när demens-stadiet nåtts är de sjukliga förändringarna långt framskridna och många nervceller har redan dött. För att möjliggöra tidig insättning av kommande behandlingar är det därför viktigt att identifiera patienter med begynnande AD, där symtomen och de sjukliga förändringarna i hjärnan ännu inte är så utbredda. Lindrig kognitiv svikt (eng. Mild Cognitive Impairment, MCI) innefattar personer med lättare intellektuella nedsättningar (ofta lättare minnessvårigheter), men som ännu inte utvecklat demens. En stor del av dessa personer har en underliggande AD, men många har också andra orsaker till besvären. Tyvärr finns inget säkert sätt att urskilja vilka personer med MCI som har underliggande AD.&lt;br/&gt;&lt;br&gt; Därför valde jag att studera metoder för tidig upptäckt av AD hos patienter med MCI.&lt;br/&gt;&lt;br&gt; Från början ingick 137 patienter med MCI i studierna. Vid första besöket togs prov från ryggvätskan (cerebrospinal-vätskan) samt plasmaprov. I ryggvätskan mättes bland annat nivåerna av Aβ42, totala mängden tau (T-tau) och fosforylerat tau (P-tau), markörer som är förändrade vid AD demens. Efter cirka 5 år hade 57 av patienterna utvecklat AD demens. I delarbete 1 visades att nivåerna av Aβ42, T-tau och P-tau, som mättes vid första besöket, med stor säkerhet kunde urskilja dessa patienter. Eftersom risken för att utveckla AD demens hos patienter med MCI troligen finns under lång&lt;br/&gt;&lt;br&gt; tid, följdes patienter upp en gång till efter cirka 9 år från första besöket för att säkerställa att majoriteten av de patienter med MCI som hade underliggande AD fångades upp. Då hade 72 patienter utvecklat AD demens. Förmågan att urskilja vilka patienter som senare utvecklade AD demens var fortfarande stor, vilket redovisades i delarbete 2. Dessutom var nivåerna av Aβ42 i ryggvätskan redan var fullständigt förändrade så tidigt som 10 år innan debuten av demens. Det visade sig också att de patienter som utvecklade AD demens inom kort tid (0-5 år) från nybesöket hade mer förändrade nivåer av T- och P-tau än de som fick demens senare.&lt;br/&gt;&lt;br&gt; I delarbete 3 mättes nivåerna av Aβ42 och T-tau i ryggvätskan två gånger, med 1-2 års intervall, hos patienter med konstaterad AD demens. Nivåerna skilde sig inte mycket över tid. Dock tenderade T-tau att stiga med tiden.&lt;br/&gt;&lt;br&gt; I delarbete 4 mättes nivåerna i ryggvätska och plasma av receptorerna till tumor necrosis factor-α (TNF-α), som är inflammatoriska markörer. Nivåerna var förhöjda hos patienter med MCI som senare utvecklade AD demens. Dessutom fanns det ett samband mellan nivåerna av TNF-α-receptorerna och komponenter i omsättningen av amyloid, ett protein man tror är påverkat vid AD.&lt;br/&gt;&lt;br&gt; I delarbete 5 sågs att nivåerna i plasma av receptorn CD40, som också är viktig vid inflammation, var förhöjda hos de patienter med MCI som senare utvecklade AD demens.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis visar jag i avhandlingen att Aβ42, T-tau och P-tau i ryggvätska med stor säkerhet kan upptäcka AD långt tidigare än patienterna har nått demens-stadiet. Tidig upptäckt av AD är en förutsättning för insättning av kommande, förhoppningsvis bromsande, behandlingar. Dock behöver man kombinera dessa markörer med andra undersökningsmetoder för att optimera precisionen. Resultaten från studie 2 och 3 tyder dessutom på att förändringen av tau i ryggvätska kommer något senare än Aβ42, som redan är helt förändrat 10 år innan debuten av demens. Inflammatoriska markörer är också förhöjda hos patienter med tidig AD och verkar ha ett samband med amyloid-omsättningen vid uppkomsten av sjukdomen. Dessa markörer kan också vara viktiga i studier av nya mediciner mot AD, särskilt de som har som mål att påverka den inflammatoriska processen.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/dcbb28a3-1d3e-4965-9673-2cf76f9381f9</url> </location> </relatedItem> <originInfo> <publisher>Clinical Memory Research Unit, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Alzheimer’s disease</topic> <topic>Mild Cognitive Impairment</topic> <topic>Biomarkers</topic> <topic>Prediction</topic> <topic>Cerebrospinal fluid</topic> <topic>Amyloid.</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-72-3</identifier> <identifier type="oldLupId">1845269</identifier> <part> <detail type="volume"> <number>2011:23</number> </detail> <extent unit="pages"> <total>106</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-04-01T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>dcbb28a3-1d3e-4965-9673-2cf76f9381f9</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:30+02:00</recordDateApproved> </recordInfo> </mods>

Caveolins and cavins as well as cholesterol are required for the structure and function of caveolae. The papers summarized in this thesis examine the role of caveolae in smooth muscle function.&lt;br/&gt;&lt;br&gt; Ca2+-sensitization is a contractile process depending on inhibition of myosin phosphatase activity. Here I test whether protein kinase C and Rho-associated kinase-mediated Ca2+ sensitization depends on caveolae using gene disrupted (KO) mice. While the process of Ca2+ sensitization was unaffected by lack of caveolae in the intestine, α1-adrenergic and protein kinase C-mediated arterial contraction was increased. Arteries lacking caveolae weighed more per unit length, suggesting growth&lt;br/&gt;&lt;br&gt; of the arterial wall. I go on to demonstrate that small resistance arteries from KO mice are remodelled, and that these and other changes counterbalance an excessive NO production to normalize blood pressure in caveolin-1 deficient mice. &lt;br/&gt;&lt;br&gt; NO production is required for initiating and maintaining penile erection. Surprisingly, nerve-induced relaxation and relaxation in response carbachol and sodium nitroprusside was impaired in caveolae-deficient corpus cavernosum.&lt;br/&gt;&lt;br&gt; In the last two papers, I examine the role of caveolae in detrusor function. Disruption of caveolae using desorption of cholesterol was first shown to impair contraction of human bladder strips in response to muscarinic receptor activation. I then demonstrate that the membrane density of caveolae increases after bladder outlet obstruction in&lt;br/&gt;&lt;br&gt; the rat. The latter effect was due to crowding of the same relative number of caveolin molecules on a smaller relative membrane area.&lt;br/&gt;&lt;br&gt; In conclusion, a considerable body of evidence has been gathered that demonstrate an important and pleiotropic physiological and pathophysiological role of caveolae in smooth muscle</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/20ca4c40-b3b7-4450-9e68-036d00fdf3a5</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="YuliaCover.pdf">https://portal.research.lu.se/files/3325600/1716728.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">682429</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Yulia_Shakirova.pdf">https://portal.research.lu.se/files/3325602/1716726.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7747365</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Dokumentdatablad_Shakirova.pdf">https://portal.research.lu.se/files/3325604/1716727.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">137339</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Caveola</topic> <topic>caveolin</topic> <topic>detrusor</topic> <topic>cavin</topic> <topic>smooth muscle contractility</topic> <topic>remodelling</topic> <topic>NO</topic> <topic>vascular dysfunction</topic> <topic>smooth muscle</topic> <topic>erectile dysfunction</topic> </subject> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-27-3</identifier> <identifier type="oldLupId">1716723</identifier> <part> <detail type="volume"> <number>2010:111</number> </detail> <extent unit="pages"> <total>114</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-12-09T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>20ca4c40-b3b7-4450-9e68-036d00fdf3a5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:41+02:00</recordDateApproved> </recordInfo> </mods>

The disease is manifested by spontaneous recurrent seizures, caused by hypersynchronized neuronal activity due to imbalance in the brain between the inhibition and excitation. Symptoms are treated with anti-epileptic drugs, but unfortunately, 30-40% of patients respond poorly to current treatment. Therefore, more efficient treatments with disease modifying or curing effects need to be developed. In the brain there are naturally occurring endogenous proteins affecting the survival and growth of brain cells, called neurotrophic factors. There are also neuropeptides, which are involved in signaling between brain cells. Both neurotrophic factors and neuropeptides have been shown to have an important role in suppressing epileptic activity. In this thesis, we focused on one neurotrophic factor and two neuropeptides that have demonstrated anti-epileptic properties; vascular endothelial growth factor (VEGF), neuropeptide Y (NPY), and galanin. To study these molecules, we have used different animal models of epilepsy and investigated the effect on epileptic seizures by enhancing the expression of these endogenously occurring proteins and/or their receptors in the brain of experimental animals. The levels of NPY, NPY receptors (Y2 or Y5), galanin and VEGF receptor 2 (Flk-1) were enhanced by using three different strategies. In the first study, we used genetically modified transgenic mice that increase the expression of VEGF receptor 2. In the second study, genetically modified cells were developed to release galanin. These cells were then placed into special capsules built of semipermeable membranes and subsequently implanted in the brain. The cells could thereby release galanin into the tissue through the membrane and in turn receive nutrients from the surrounding tissue. This approach has the advantage that, in case of adverse effects, the capsules filled with genetically modified cells easily can be removed from the brain. In the third and fourth studies we examined the effects of the combinatorial gene therapy of NPY and either Y2 or Y5 receptors on epileptic seizures by enhancing their expression with viral vectors. By enhancing the expression of the mentioned proteins and receptors in the brain, we have been able to reduce the number, duration and severity of epileptic seizures in animal models. Increased expression of VEGF receptor 2 (Flk-1) or increased extracellular levels of galanin by encapsulated cell biodelivery (ECB) inhibited focal epileptic seizures. The combinatorial treatmentwith NPY and either Y2 or Y5 receptors, on the other hand, also affected generalized seizures. All these approaches, particularly the viral vector-based treatment, have a potential to be developed into an alternative treatment strategies for epilepsy.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Epilepsi är en allvarlig kronisk neurologisk sjukdom, som drabbar ungefär 1% av befolkningen. Sjukdomen yttrar sig genom plötsliga återkommande krampanfall, som beror på en obalans i hjärnan mellan hämmande (inhibitoriska) och stimulerande (excitatoriska) nervimpulser. När de stimulerande impulserna tar överhand leder detta till överstimulering, också kallad för hyperexcitabilitet, som ger upphov till epileptiska kramper. Symptomen behandlas med väletablerade&lt;br/&gt;&lt;br&gt; antiepileptiska läkemedel men mer än var tredje patient svarar inte som förväntat på behandlingen utan den epileptiska aktiviteten blir återkommande. För att öka livskvalitén hos epilepsipatienter genom att förebygga epileptiska kramper, samt att kunna ersätta en mångårig medicinsk behandling med svåra biverkningar krävs nya och mer effektiva behandlingsalternativ.&lt;br/&gt;&lt;br&gt; I hjärnan finns naturligt förekommande proteiner, ett exempel är neurotrofiska faktorer, som påverkar överlevnad och tillväxt av hjärnceller. Det finns också neuropeptider, som påverkar signalering mellan hjärnceller. Både neurotrofiska faktorer och neuropeptider har visat sig ha en hämmande roll vid epileptisk aktivitet i hjärnan. I den här avhandlingen har vi fokuserat på två neuropeptider och en neurotrofiska faktor som har uppvisat anti-epileptiska egenskaper,&lt;br/&gt;&lt;br&gt; nämligen vaskulär endotelcellstillväxtfaktor (VEGF), neuropeptid Y (NPY) och galanin. För att studera dessa proteiner närmare, har vi använt oss av djurmodeller för epilepsi. Genom att förstärka uttrycket av dessa naturligt förekommande ämnen samt deras receptorer i hjärnan på försöksdjur har vi undersökt effekten på epileptiska kramper. Nivåerna har förstärkts genom tre olika strategier. I den&lt;br/&gt;&lt;br&gt; första studien användes transgena möss, där en genetisk förändring påverkar uttrycket av VEGF receptor 2 (Flk-1). I den andra studien utvecklades genetiskt modifierade celler för att frisätta galanin som sedan placerades i speciella membran och implanterades i hjärnan i området där den epileptiska aktiviteten uppkommer. Cellerna kan på så sätt frisätta galanin genom det semipermeabla membranet samtidigt som de inkapslade cellerna kan ta upp näringsämnen från den omkringliggande vävnaden för överlevnad. De inkapslade cellerna integreras inte med den kroppsegna vävnaden, vilket möjliggör att de inkapslade cellerna kan avlägsnas vid eventuella biverkningar. I den tredje och fjärde studien undersöktes den hämmande effekten av epileptiska kramper genom att förstärka uttrycket av både NPY och antingen Y2 eller Y5 receptorer. När NPY uttrycks i kombination&lt;br/&gt;&lt;br&gt; med en av sina receptorer ökar effekten av behandlingen.&lt;br/&gt;&lt;br&gt; Genom att förstärka uttrycket av ovannämnda proteiner samt deras receptorer i hjärnan har vi kunnat reducera antalet, varaktigheten och svårighetsgraden av epileptiska kramper. Med ökat uttryck av VEGF receptor 2 (Flk-1) och med galanin har mildare epileptiska kramper kunnat hämmas. Den kombinatoriska behandlingen, med NPY och antingen Y2 eller Y5 receptorer påverkade även svårare generaliserade kramper, vilket gör den lämplig som en alternativ behandling för epilepsi.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3d90afd5-29c3-49f1-a092-41e3aa82dfb3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Litsas_Thesis.pdf">https://portal.research.lu.se/files/3325974/3559266.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7382401</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Neurology, Lund</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Epilepsy</topic> <topic>Gene Therapy</topic> <topic>Neuropeptide Y</topic> <topic>Y2 receptor</topic> <topic>Y5 receptor</topic> <topic>Galanin</topic> <topic>Encapsulated cell biodelivery</topic> <topic>Vascular endothelial growth factor</topic> <topic>Flk-1</topic> <topic>Hippocampus</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-03-1</identifier> <identifier type="oldLupId">3559258</identifier> <part> <detail type="volume"> <number>2013:33</number> </detail> <extent unit="pages"> <total>110</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-03-22T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>3d90afd5-29c3-49f1-a092-41e3aa82dfb3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:47+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:47+02:00</recordDateApproved> </recordInfo> </mods>

Yet, the exact phenotype and spatial distribution of primary MSC in the human BM are unknown. Their cultured progeny are promising candidates for clinical applications. MSC cultures however, are heterogeneous and, while critical for clinical applications, their exact composition is not known. &lt;br/&gt;&lt;br&gt; We have therefore analysed the phenotype of primary MSC in the BM and found that mesenchymal progenitors were highly enriched in the lin-/CD271+/CD45- fraction. Interestingly, CD146 expression pertained to the in-vivo localization of primary MSC in the human bone marrow (perivascular/endosteal) while CD146 expression in-vitro was oxygen level dependent. Cultured MSC were analysed after carboxyﬂuorescein succinimidyl ester (CFSE) staining for cell division tracking. Sorting for slowly dividing and rapidly dividing sub-populations and global gene expression analysis yielded 102 differentially expressed genes. Two of these genes translated into proteins that enabled for the prospective identiﬁcation of a VCAM+/ FMOD+ sub-population, with low progenitor activity and a limited differentiation potential.&lt;br/&gt;&lt;br&gt; On the other hand, MSC support tumour growth and metastasis and have even been suggested as osteosarcoma (OS) stem cells. We therefore analysed MSC in OS (OS-MSC) and compared them with BM-MSC. OS samples contained very high frequencies of mesenchymal progenitor cells. OS-derived MSC (OS-MSC) did not show chromosomal aberrations, had normal MSC morphology and expressed the typical MSC surface marker proﬁle. A global gene expression analysis yielded a set of genes differentially expressed between OS- and BM-MSC. Of these, 3 genes responsible for membrane-associated proteins were analysed: CD142, LY6H, and OSS3* were 24.9- , 7.2- , and 66.4-fold higher expressed in OS-MSC. The OSS3-protein was expressed in all analysed primary OS samples and only OSS3 identiﬁed the majority of mesenchymal progenitor cells in uncultured tumour samples.&lt;br/&gt;&lt;br&gt; Taken together, we propose here a marker combination for a highly enriched primary MSC population and show that CD146 expression relates to the perivascular (versus endosteal) localization of primary human MSC. This is of importance to further studies of the haematopoietic environment. We also show the presence of sub-populations within MSC cultures and propose markers for the isolation of a functionally impaired population. This is important for safe and efﬁcient clinical application of cultured MSC. Furthermore we could demonstrate high numbers of colony forming mesenchymal progenitors in OS, suggesting that MSC are a major constituent of the OS stroma and consequently represent a target for therapy. Finally the above data show that a sub-population of OS cells expresses OSS3 and we furthermore demonstrate that OSS 3 identiﬁes the majority of colony forming mesenchymal progenitors within OS. Presumably, these cells are the origin of a considerable part of the CAF population within the tumour and they should therefore be considered a target for therapy. Experiments investigating the use of OSS3 antibodies in an antibody-dependent cell-mediated cytotoxicity-based approach are currently underway. &lt;br/&gt;&lt;br&gt; *Due to a possible patent application, we were advised to substitute the original gene name with an alias.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Mesenkymala stamceller (MSC) kan isoleras från en rad olika vävnader &lt;br/&gt;&lt;br&gt; i kroppen, bland annat från benmärg. De kan differentiera till ben, brosk, &lt;br/&gt;&lt;br&gt; fett- och bindvävnad men deras exakt roll i kroppen är inte väl känd. &lt;br/&gt;&lt;br&gt; Den senaste forskningen tyder dock på att en av deras huvuduppgifter är &lt;br/&gt;&lt;br&gt; att stödja blodbildningen som sker av blod- eller hematopoetiska &lt;br/&gt;&lt;br&gt; stamceller. Man antar att MSC bildar den hematopoetiska stamcellens &lt;br/&gt;&lt;br&gt; omgivning (eller niche) och därifrån stödjer blodbildningen. &lt;br/&gt;&lt;br&gt; MSC är väldigt enkla att isolera från kroppen och odlar man dem i &lt;br/&gt;&lt;br&gt; inkubator så växer de snabbt och behåller sin differentieringsförmåga. &lt;br/&gt;&lt;br&gt; Bland annat är det differentieringspotentialen som gör att dessa celler är &lt;br/&gt;&lt;br&gt; intressanta kandidater för kliniska användningsområden (t.ex. &lt;br/&gt;&lt;br&gt; transplantation). Inom denna ram är det viktigt att samla information om &lt;br/&gt;&lt;br&gt; dessa celler och karakterisera cellerna såväl i deras naturliga omgivning &lt;br/&gt;&lt;br&gt; (kroppen) som i inkubatorn. Detta var målen med delarbete (I) och &lt;br/&gt;&lt;br&gt; delarbete (II). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Inom (I) kunde vi visa att man med hjälp av cellmarkörer (nämligen &lt;br/&gt;&lt;br&gt; CD271, CD45 och CD146) kan isolera en renare stamcellspopulation än &lt;br/&gt;&lt;br&gt; man tidigare kunnat. Dessutom kunde vi visa att MSC i benmärgen finns &lt;br/&gt;&lt;br&gt; i olika omgivningar, att dessa omgivningar möjligtvis kan relatera till &lt;br/&gt;&lt;br&gt; olika typer av hematopoetiska stamceller och att dessa omgivningar kan &lt;br/&gt;&lt;br&gt; skiljas åt med hjälp av en cellmarkör som heter CD146. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I delarbete (II) analyserade vi odlade mesenkymala stamceller och &lt;br/&gt;&lt;br&gt; hittade en subpopulation som hade en mindre växt- och &lt;br/&gt;&lt;br&gt; differentieringsförmåga än huvudpopulationen vilket kan vara viktigt när &lt;br/&gt;&lt;br&gt; man planerar att transplantera cellerna. &lt;br/&gt;&lt;br&gt; Mesenkymala stamceller verkar inte bara inneha en stödjande roll vid &lt;br/&gt;&lt;br&gt; blodbildning men också vid tillväxt och spridning av tumörer. För &lt;br/&gt;&lt;br&gt; delarbete (III) valde vi att analysera en speciell typ av bencancer &lt;br/&gt;&lt;br&gt; (osteosarkom) där målet var att isolera och karakterisera eventuellt &lt;br/&gt;&lt;br&gt; förekommande MSC. Vi visade att det finns MSC i osteosarkom och att &lt;br/&gt;&lt;br&gt; dessa celler var väldigt lika MSC isolerade från frisk benmärg. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Målet med delarbete (IV) var att identifiera eventuella skillnader mellan &lt;br/&gt;&lt;br&gt; mesenkymala stamceller från bencancer och mesenkymala stamceller &lt;br/&gt;&lt;br&gt; isolerade från frisk vävnad. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi kunde visa att det inte bara fanns likheter mellan MSC från &lt;br/&gt;&lt;br&gt; osteosarkom och MSC från benmärg utan också skillnader: Vissa cell &lt;br/&gt;&lt;br&gt; markörer (som t.ex. CD142, LY6H och OSS3) förekom bara på MSC &lt;br/&gt;&lt;br&gt; från osteosarkom. Förhoppningsvis kommer dessa skillnader att kunna &lt;br/&gt;&lt;br&gt; användas som utgångspunkt för nya terapier där målet är att kapa det &lt;br/&gt;&lt;br&gt; stöd som de tumörstödjande mesenkymala stamcellerna ger. Preliminära &lt;br/&gt;&lt;br&gt; analyser kring detta utförs i skrivande stund.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;b&gt;Popular Abstract in German&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Mesenchymale Stammzellen (MSZ) können aus einer Reihe &lt;br/&gt;&lt;br&gt; verschiedener Gewebe des menschlichen Körpers isoliert werden und sie &lt;br/&gt;&lt;br&gt; sind in der Lage zu Knochen, Knorpel, Fett- und Bindegewebe zu &lt;br/&gt;&lt;br&gt; differenzieren. Über die genaue Funktion dieser Zellen im Körper ist &lt;br/&gt;&lt;br&gt; noch nicht viel bekannt. Neueste Forschungsergebnisse deuten jedoch &lt;br/&gt;&lt;br&gt; darauf hin, dass die Unterstützung der Blutbildung eine ihrer &lt;br/&gt;&lt;br&gt; Hauptaufgaben darstellt. Blut wird von Blut- oder Hämatopoetischen &lt;br/&gt;&lt;br&gt; Stammzellen (HSZ) gebildet und man nimmt an, dass MSZ die direkte &lt;br/&gt;&lt;br&gt; Umgebung der HSZ bilden (deren Nische) und von hier die Blutbildung &lt;br/&gt;&lt;br&gt; unterstützen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; MSZ lassen sich verhältnismässig leicht aus Gewebeproben eines &lt;br/&gt;&lt;br&gt; Spenders isolieren. In Kultur ausserhalb des Körpers wachsen die Zellen &lt;br/&gt;&lt;br&gt; schnell und behalten ihr Differenzierungspotential. Dieses &lt;br/&gt;&lt;br&gt; Differenzierungspotential ist es unter anderem, was die Zellen zu &lt;br/&gt;&lt;br&gt; interessanten Kandidaten für klinische Anwendungsbereiche (z. Bsp.: &lt;br/&gt;&lt;br&gt; Transplantation) macht. Vor diesem Hintergrund ist es wichtig diese &lt;br/&gt;&lt;br&gt; Zellen besser zu charakterisieren, sowohl in ihrer natürlichen Umgebung &lt;br/&gt;&lt;br&gt; (im Körper) als auch in Kultur im Inkubator. Dieses Ziel wurde in den &lt;br/&gt;&lt;br&gt; Arbeiten (I) und (II) verfolgt. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In Studie (I) konnten wir zeigen, dass man mit Hilfe einer Gruppe von &lt;br/&gt;&lt;br&gt; Oberflächenmolekülen (CD271, CD45 und CD146) eine Stammzell- &lt;br/&gt;&lt;br&gt; population isolieren kann, die wesentlich höher aufgereinigt ist, als es &lt;br/&gt;&lt;br&gt; bisher möglich war. Darüber hinaus konnten wir zeigen, dass sich MSZ &lt;br/&gt;&lt;br&gt; im Knochenmark an unterschiedlichen Positionen befinden, und das die &lt;br/&gt;&lt;br&gt; Ursprungsposition einer Zelle im Zusammenhang mit dem &lt;br/&gt;&lt;br&gt; Vorhandensein des Oberflächenmoleküls CD146 steht. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In Arbeit (II) analysierten wir kultivierte MSZ und konnten nachweisen, &lt;br/&gt;&lt;br&gt; dass sich in den Kulturen Subpopulationen befinden, die ein geringeres &lt;br/&gt;&lt;br&gt; Wachstums- und Differenzierungspotential besitzen, als der Rest der &lt;br/&gt;&lt;br&gt; Zellen. Diese Information könnte bei der therapeutischen Anwendung &lt;br/&gt;&lt;br&gt; (Transplantation) kultivierter Zellen von Nutzen sein. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Mesenchymale Stammzellen scheinen allerdings nicht nur die &lt;br/&gt;&lt;br&gt; Blutbildung zu unterstützen, sondern auch die Entstehung und &lt;br/&gt;&lt;br&gt; Ausbreitung von Tumoren. Aus diesem Grund analysierten wir in Studie &lt;br/&gt;&lt;br&gt; (III) einen häufig vorkommenden Knochentumor (Osteosarkom) mit &lt;br/&gt;&lt;br&gt; dem Ziel eventuell vorkommende MSZ zu isolieren und zu &lt;br/&gt;&lt;br&gt; charakterisieren. Wir konnten zeigen, dass MSZ in hoher Zahl im &lt;br/&gt;&lt;br&gt; Osteosarkom vorkommen und dass diese MSZ jenen, aus dem &lt;br/&gt;&lt;br&gt; Knochenmark isolierten, sehr ähnlich sind. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Das Ziel von Arbeit (IV) war es schliesslich möglicherweise &lt;br/&gt;&lt;br&gt; vorhandene Unterschiede zwischen MSZ aus gesundem Knochenmark &lt;br/&gt;&lt;br&gt; und MSZ aus Tumoren zu identifizieren. Unsere Daten zeigen, dass &lt;br/&gt;&lt;br&gt; nicht nur Ähnlichkeiten bestanden sondern auch Unterschiede. Einige &lt;br/&gt;&lt;br&gt; Oberflächenmoleküle (CD142, LY6H und OSS3) befanden sich &lt;br/&gt;&lt;br&gt; beispielsweise hauptsächlich auf MSZ die aus einem Osteosarkom &lt;br/&gt;&lt;br&gt; isoliert worden sind. Diese Unterschiede können hoffentlich den &lt;br/&gt;&lt;br&gt; Ausgangspunkt für neue Krebstherapien bilden, mit dem Ziel die &lt;br/&gt;&lt;br&gt; Tumorunterstützung durch mesenchymale Stammzellen zu unterbrechen &lt;br/&gt;&lt;br&gt; und damit das Wachstum und die Ausbreitung des Tumors zu &lt;br/&gt;&lt;br&gt; verlangsamen.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/32e4c3c7-9ae4-4a90-8882-ef8293fac413</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>mesenchymal stem cells</topic> <topic>stromal cells</topic> <topic>bone marrow stem cells</topic> <topic>tumour stroma</topic> <topic>stroma-directed anti-tumour therapy</topic> <topic>osteosarcoma</topic> </subject> <subject authority="lup"> <topic>Hematology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-71-6</identifier> <identifier type="oldLupId">1834853</identifier> <part> <detail type="volume"> <number>2011:22</number> </detail> <extent unit="pages"> <total>146</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-03-25T13:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Hypoxia, or deficient oxygen supply, is a common feature of the expanding tumor which alters cell metabolism and consecutively causes lowered intracellular pH. To alleviate hypoxic and acidotic stress, cancer cells respond by promoting blood vessel formation, angiogenesis, and by activating mechanisms for increased acid-base control. These adaptive processes involve complex modes of cell communication in the tumor microenvironment. &lt;br/&gt;&lt;br&gt; The aim of this thesis was to investigate the role of extracellular vesicles (EVs) in the hypoxic tumor microenvironment and the mechanisms by which EVs mediate cell-cell communication as well as regulatory aspects of hypoxia-induced acidosis. In the first part (papers I and II), we provide new insights into the mechanisms of EV transfer between cells. It is demonstrated that a significant proportion of cancer cell-derived EVs is transferred into recipient cells by binding to the glycan chains of the cell surface receptors, heparan sulfate proteoglycans (PGs). We further show that EVs are internalized through a lipid raft-mediated endocytosis pathway negatively regulated by caveolin-1. In the second part (papers III and IV), we show that EVs originating from hypoxic cancer cells exhibit a specific molecular profile and induce a more pronounced pro-angiogenic response in endothelial recipient cells and in an in vivo tumor model as compared to normoxia-derived EVs. EVs may thus serve as biomarkers wherein tumor specific conditions, such as hypoxia, are reflected. Finally, we found that EVs may constitute a functionally active route for the release of the major pH regulatory enzyme, carbonic anhydrase IX (CAIX). Molecular studies revealed that CAIX in cells and in EVs can be substituted with specific glycosaminoglycan chains, defining CAIX as a part-time PG. &lt;br/&gt;&lt;br&gt; These findings advance our understanding of the role of EV-dependent signaling in the tumor microenvironment. Data presented in this thesis identify molecular mechanisms by which EVs mediate cell-cell communication that constitute potential targets for therapeutic interventions.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Cancerceller är celler som på grund av mutationer, felaktigheter i cellernas DNA, har erhållit förmågan att dela sig ohämmat. Celler behöver tillgång till syre och näring för att överleva, vilket levereras via kroppens blodkärl. Den snabba tillväxten av tumörvävnad leder dock till att befintlig blodtillförsel inte räcker till och delar av tumörerna drabbas därför av syrebrist, så kallad hypoxi. Hypoxiska cancerceller signalerar då till omgivande blodkärlsceller att börja bilda nya kärl för att förbättra blodtillförseln. Cancercellerna har även utvecklat andra mekanismer för att hantera syrebrist. Genom att t.ex. ställa om sin ämnesomsättning till en ökad nedbrytning av socker kan de generera nödvändig energi på ett sätt som inte kräver tillgång till syre. Dessvärre leder nedbrytning av socker till en överproduktion av restprodukter som gör cellerna sura. Karbanhydras IX (CAIX) är ett enzym som hjälper celler att reglera mängden sura ämnen. CAIX finns i förhöjda nivåer i tumörvävnad vilket är kopplat till sämre prognos i många cancertyper. CAIX är således ett tänkbart mål för cancerterapi och det är därför viktigt att förstå hur CAIX regleras i tumören. &lt;br/&gt;&lt;br&gt; Cancercellerna anpassar sig alltså efter den ogästvänliga miljön som råder i tumören och kommunicerar med de omgivande cellerna, t.ex. blodkärlsceller, för att på bästa sätt justera sina förutsättningar för tillväxt till det bättre. Celler kommunicerar genom att skicka olika signalsubstanser till varandra, dessa kan liknas vid små brev med instruktioner till mottagarcellen om hur de ska bete sig. En typ av cellkommunikation som nyligen upptäckts sker via frisättning av små membranomslutna blåsor, så kallade extracellulära vesikler (EVs). Till skillnad från en enskild signalsubstans innehåller EVs en stor mängd molekylär information och kan liknas vid stora paket med instruktioner. EVs som skickas från tumörceller har visat sig bidra till en ökad blodkärlsbildning och tumörtillväxt. Vad som påverkar vesiklernas innehåll och hur det överförs till mottagarceller är inte helt känt. Detta avhandlingsarbete har undersökt hur EVs från cancerceller tas emot av mottagarceller. EVs påverkan på blodkärlsbildning och reglering av sura ämnen har även studerats samt hur detta påverkas av hypoxi. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Överföring av extracellulära vesikler mellan celler&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har funnit en process där kolesterolrika regioner i cellens membran är viktiga för att EVs ska tas in i mottagarcellen över cellens membran. Proteinet Caveolin-1, som finns i dessa membranregioner, visade sig kontrollera upptaget så att mindre EVs tas upp. Det är tidigare visat att denna typ av region i cellens membran kan fungera som centrum för bildning av EVs. De kolesterolrika membranregionerna fungerar på så sätt som en slags postcentral för mottagning och utskick av paket med information. &lt;br/&gt;&lt;br&gt; Vidare har vi identifierat ett sorts cellyteprotein, heparansulfate-proteoglykaner (HSPGs), som en viktig mottagare för upptag av EVs. EVs fastnar på långa, negativt laddade sockerkedjor som sitter på HSPGs, vilket gör att HSPGs tar med sig den bundna vesikeln in i cellen. Det visade sig också att det väletablerade läkemedlet heparin, som liknar sockerkedjorna på HSPGs, kan hämma en stor del av EV-upptaget i celler och sannolikt även deras tumörstimulerande effekter, genom att konkurreara med bindningen mellan EVs och HSPG. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Syrebrist påverkar extracellulära vesiklers innehåll och funktion&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I den andra delen av detta avhandlingsarbete studerade vi hur hypoxi påverkar innehållet i EVs och hur EVs från hypoxiska cancerceller påverkar mottagarceller jämfört med EVs från normalt syresatta celler. Experiment med blodkärlsceller visade att hypoxiska EVs får cellerna att efterlikna processer som förekommer vid blodkärlsbildning i större utsträckning än normala EVs. Hypoxiska EVs kan alltså öka tumörens förmåga att nybilda blodkärl och på så sätt även dess tillväxt. Vissa molekyler som enbart fanns i hypoxiska EVs återfanns även i EVs som isolerades från cancerpatienters blod, vilket kan innebära en möjlig användning av EVs som markörer för cancersjukdom. Vi upptäckte även att CAIX transporteras på EVs från cancerceller. Frisättning av CAIX via EVs kan på så sätt reglera nivån av sura ämnen, på avstånd från celler som uttrycker CAIX. EVs skulle därmed kunna bidra till en bättre tumör miljö och på så sätt gynna tumörens förutsättningar för fortsatt tillväxt. &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har vi kartlagt en rad processer som styr hur cancercellerna påverkar sin omgivning med hjälp av EVs samt identifierat viktiga komponenter som kontrollerar cellens upptag av EVs. Detta utgör en viktig funktion i överföring av information mellan celler i tumörvävnaden, vilken skulle kunna utnyttjas för att förhindra en central del av cancercellernas kommunikation. Resultaten som presenteras i den här avhandlingen belyser även möjligheter att använda EVs för att få information om tumörens tillstånd, något som är viktigt för att kunna avgöra patienternas prognos och hur de svarar på olika behandlingar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1f7944c9-9d7e-4d44-b129-779b0986f009</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Helena_Christianson_-_thesis.pdf">https://portal.research.lu.se/files/3329332/4814871.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">20654367</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Oncology, Department of Clinical Sciences</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>microvesicle</topic> <topic>exosome</topic> <topic>Key words Extracellular vesicle</topic> <topic>glioblastoma</topic> <topic>hypoxia</topic> <topic>angiogenesis</topic> <topic>acidosis</topic> <topic>proteoglycan</topic> <topic>endocytosis</topic> <topic>carbonic anhydrase IX</topic> <topic>biomarker.</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-078-4</identifier> <identifier type="oldLupId">4814870</identifier> <part> <detail type="volume"> <number>2014:149</number> </detail> <extent unit="pages"> <total>96</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-12-19T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>1f7944c9-9d7e-4d44-b129-779b0986f009</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:57+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:57+02:00</recordDateApproved> </recordInfo> </mods>

During the 1990s, major changes in the regulations governing the use of synthetic refrigerants took place in Sweden. This resulted in many refrigeration systems being converted to systems with indirect cooling by means of a liquid secondary refrigerant. The cooling coil is an important component in a display cabinet and traditionally, different kinds of tube-coils, with aluminium fins on expanded circular copper tubes, have been used. Many secondary heat transfer media have relatively high viscosities at low tem¬peratures, and so the flow regime is often laminar, which may lead to poor heat transfer. However, it is possible to achieve high heat transfer coefficients even for laminar flows if an ap¬propriate design of the heat exchanger is applied. Flat-tube heat exchangers have been used for a long time in automotive applications, where compactness is important. The display cabinet application involves low air velocities in combination with condensation of water vapour, and sometimes even frosting, and is therefore different from other applications where flat-tube heat exchangers have been used earlier.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The objective of this research work has been to find a suitable, more energy-efficient, heat exchanger design for indirectly cooled display cabinets. An efficiency that would mean that temperature differences would be so small that frosting could be avoided was aimed for. This research work has sandwiched experimental investigations with theoretical modelling and parameter studies. Initially, the heat transfer and pressure drop performance of conventional cooling coils operating with liquid secondary refrigerants was studied in full-scale experiments. Thereafter, the liquid-side (or tube-side) heat transfer was studied experimentally in small-scale experiments on three single multiport extruded flat tubes with different cross-sections. In both studies, the best agreement was found with predictions using the Gnielinski correlation for thermally developing laminar flows with the constant temperature boundary condition. After this, two different heat exchangers having flat tubes and plain fins on the air side were evaluated experimentally - one with continuous plate fins and one with serpentine fins. The results show that, for conditions similar to those of display cabinets, the heat transfer and pressure drop performance is affected to little or no extent by the occurrence of condensate water. Models for different types of flat-tube heat exchangers were thereafter created using the results from the experimental studies. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In order to find appropriate optimising criteria for the display cabinet heat exchangers, the energy efficiency of a complete cooling system of an imagined supermarket has been studied. Finally, different designs of flat-tube heat exchangers with plain fins have been evaluated theoretically in a parameter study. The results show that considerable savings in the required electric drive power can be obtained in comparison with the traditional cooling coil. The savings can be up to 15 %. In addition, the flat-tube heat exchangers could operate with a minimum temperature difference of around 1 K. This makes frost-free operation possible for many display cabinet applications and thereby the savings potential even larger.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Resultaten som presenteras i denna doktorsavhandling visar att det går att spara stora mängder energi genom att använda samma typ av värmeväxlare, som normalt används i bilar och lastbilar, i livsmedelsbutikernas kyldiskar. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att hålla maten kall när den ligger ute i butiken cirkuleras en kyld luftström runt i kyldiskarna. Denna kyls i en så kallad värmeväxlare som ofta finns i botten på kyldiskarna under den nedersta hyllan. Bakgrunden till forskningsprojektet är att det i Sverige under 90-talet infördes en anvisning som inte tillät att luften i kyldiskarna kyldes direkt med hjälp av konstgjorda köldmedier. Anvisningen gällde vid nybyggen av butikernas kylsystem. Istället skulle en vätska kylas i kylmaskinerna och denna vätska, den så kallade köldbäraren, skulle sedan pumpas ut till kyldiskarna. Dessa system kallas indirekta kylsystem. Anledningen var att de konstgjorda köldmedierna bidrar till växthuseffekten om de släpps ut i luften. Genom att använda indirekta system behöver systemen inte fyllas med lika mycket köldmedium och det blir då lättare att hålla läckagen låga. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Köldbärarvätskorna är ofta ganska trögflytande vid låga temperaturer vilket gör att värme inte överförs så bra från luften till vätskan när luften kyls. Detta leder i sin tur till att det måste vara stora temperaturskillnader mellan luft och vätska när luften ska kylas. Ju större temperaturskillnad, desto mer elenergi måste användas. De värmeväxlare, så kallade kylbatterier, som normalt finns i kyldiskar har runda rör och var från början konstruerade för att ett köldmedium skulle koka vid låg temperatur inne i rören. När luften istället ska kylas med en trögflytande köldbärarvätska skulle kylbatterierna behöva byggas på ett annat sätt för att vara mer energieffektiva.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I bilar och lastbilar används ofta värmeväxlare med platta tuber istället för runda rör, eftersom värmeväxlarna då kan göras mindre och lättare. I detta forskningsprojekt har vi undersökt hur en värmeväxlare med platta tuber ska se ut för att fungera optimalt i en kyldisk. I bilar är luften torr och dess hastighet genom värmeväxlaren hög. I en kyldisk är hastigheten låg och dessutom bildas kondens av vattenånga när luften kyls. Dessa annorlunda förutsättningar gör att värmeväxlarna behöver se lite annorlunda ut, t.ex. vara glesare, för att fungera bra. För att komma fram till förslag på hur värmeväxlare med platta tuber bör se ut när de ska användas i kyldiskar har experiment varvats med beräkningar i många omgångar. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Resultaten visar att åtminstone 15 % elenergi kan sparas med hjälp av dessa ”nya” värmeväxlare och det kan bli stora mängder eftersom 5 meter kyldisk i en affär använder ungefär lika mycket energi per år som en eluppvärmd villa. Dessa ”nya” värmeväxlare kan eventuellt bli dyrare att producera. Hur mycket dyrare är svårt att säga eftersom det till stor del beror på tillverkningsvolym.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den anvisning som inte tillät direkt kylning med ett konstgjort köldmedium som infördes i Sverige på 90-talet har nu tagits bort och ersatts med EU-lagstiftning. Enligt denna finns det inte längre någon motsvarande anvisning, men ju mer konstgjort köldmedium som en kylanläggning fylls med, desto oftare måste man kontrollera att den inte läcker. Svenska butiker har många positiva erfarenheter av de indirekta kylsystemen – de är något dyrare att bygga, men billigare att sköta och de underlättar en jämn temperaturhållning av matvarorna. Dessutom har intresset för indirekta kylsystem ökat i resten av världen, eftersom de är miljövänliga alternativ till system med konstgjorda köldmedium. Därför är sannolikheten stor att de indirekta kylsystemen kommer att fortsätta att användas i stor utsträckning och att användningen till och med kommer att öka i framtiden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Detta forskningsprojekt utfördes på SP Sveriges Tekniska Forskningsinstitut, i samarbete med Lunds Tekniska Högskola, LTH, där avhandlingen publiceras. Chalmers Tekniska Högskola och ett antal företag som arbetar med livsmedelskyla eller värmeväxlare har också deltagit och bidragit till projektet. Projektet har huvudsakligen finansierats av Energimyndigheten, Svensk Fjärrvärme, SP och LTH.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5833ab0f-83f9-405a-97ce-63fe37610344</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Caroline_Haglund_Stignor_Doctoral_thesis.pdf">https://portal.research.lu.se/files/3329722/1292630.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1082818</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Faculty of Engineering, Department of Energy Sciences, Division of Heat Transfer</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>energy-efficiency</topic> <topic>indirect cooling</topic> <topic>display cabinet</topic> <topic>pressure drop</topic> <topic>heat transfer</topic> <topic>flat-tube heat exchanger</topic> <topic>cooling coil</topic> <topic>laminar</topic> </subject> <subject authority="lup"> <topic>Energy Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-628-7700-2</identifier> <identifier type="oldLupId">1292491</identifier> <part> <extent unit="pages"> <total>98</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-03-06T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>5833ab0f-83f9-405a-97ce-63fe37610344</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:21:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:21:58+02:00</recordDateApproved> </recordInfo> </mods>

The development of FVIII replacements has improved the situation for patients with haemophilia such that chronic arthropathy can be prevented, and life expectancy and the quality of life have increased. However, approximately 20-30% of patients suffering from severe HA develop neutralizing&lt;br/&gt;&lt;br&gt; antibodies (inhibitors) against FVIII. Alternative treatment, using by-passing agents, is available for patients exhibiting inhibitors, although these can only be used for the short-term treatment of acute haemorrhage and as prophylaxis during surgery. Furthermore, the clinical response to by-passing products is unpredictable. Two of the studies included in this thesis evaluated the response to by-passing therapy in plasma from patients with HA. The variation in thrombin&lt;br/&gt;&lt;br&gt; production within families was found to be significantly lower than the variation between families, indicating that a familial predisposition may influence thrombin formation in response to by-passing agents (Paper I). Moreover, FVIII clotting factors were found to potentiate the in vitro effect of by-passing agents on thrombin formation in plasma from patients with HA exhibiting inhibitors,&lt;br/&gt;&lt;br&gt; indicating that further assessment of this treatment strategy in a clinical context is warranted (Paper II). Not all anti-FVIII antibodies have neutralizing capacity. In the studies presented in Papers III &amp;amp; V, non-neutralizing anti-FVIII antibodies(NNAs) were investigated in two different cohorts, using an enzyme-linked&lt;br/&gt;&lt;br&gt; immunosorbent assay (ELISA). NNAs were detected in 18.9% of siblings with HA, and in 12.8% of unrelated HA subjects followed for four years. The antibody response was assayed using three different rFVIII products. The antibody response was found to be heterogeneous, to vary considerably between individuals (Papers III and V), and also over time (Paper V). None of the patients in the cohort with NNAs observed longitudinally developed inhibitors (Paper V). However, in one patient with moderate HA, the detection of Bethesda-negative anti-FVIII antibodies coincided with a change in bleeding phenotype four years prior to FVIII inhibitor development. This finding suggests that immunoassays may be a useful complement in evaluating the immune response to FVIII (Paper IV). The potential clinical impact of NNAs was evaluated in the long term study (Paper V), showing no association between age, F8 mutation, or the influence of immune system challenges on NNA development. Interestingly, patients with NNAs had significantly fewer bleeding episodes than NNA-negative patients (p=0.048), raising questions about the possibility of yet undefined types of anti-FVIII antibodies with protective or potentiating effects on FVIII.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Hemofili A är en form av blödarsjuka som beror på en medfödd defekt av&lt;br/&gt;&lt;br&gt; äggviteämnet faktor VIII (FVIII). FVIII spelar en viktig roll för att kroppens blodlevringsförmåga (s.k. koagulation) ska fungera optimalt och med nedsatt funktion hos FVIII riskerar man att drabbas av allvarliga blödningar i framför allt leder, men även i muskler, slemhinnor (t.ex. näsblödning) och i hjärnan. Ledblödningarna leder till kronisk nedbrytning av leden, s.k. artropati, vilket påverkar patientens rörelseförmåga och även livskvalitet avsevärt. Sjukdomen&lt;br/&gt;&lt;br&gt; finns i tre svårighetsgrader baserat på vilken halt av FVIII man kan uppmäta i blodplasman hos patienten: svår, moderat och mild hemofili. Patienter med svår hemofili löper en påtagligt högre risk för spontana svåra blödningar än de övriga grupperna.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den gen som styr produktionen av FVIII är belägen på den kvinnliga&lt;br/&gt;&lt;br&gt; könskromosomen, X-kromosomen, och därmed är det (i princip) endast män som drabbas av sjukdomen hemofili (ca 1 av 5000 män). En kvinna kan dock ärva det defekta genanlaget från sin mor och kan, som bärare, i vissa fall drabbas av blödningssymptom. I ca 30% av hemofilifallen finns inte sjukdomen i familjen sedan tidigare, utan beror då på att en spontan nymutation uppstått i FVIII-genen hos den drabbade individen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sverige har varit ett föregångsland när det gäller hemofilisjukvård. Redan på 1950-talet började Professor Inga Marie Nilsson på Malmö Allmänna sjukhus att introducera förebyggande behandling med FVIII (s.k. profylax) till de blödarsjuka patienterna. Hon och hennes kolleger resonerade så att då patienter med moderat och mild hemofili blöder betydligt mer sällan och inte så allvarligt som patienter&lt;br/&gt;&lt;br&gt; med svår hemofili, så borde en högre halt av FVIII i blodplasman hos de svårast drabbade patienterna göra att blödningssymptomen minskar och att sjukdomen då liknar den hos en patient med moderat/mild hemofili. Ganska snart stod det klart att teorin stämde med den kliniska bilden; patienterna blödde mindre frekvent och ledsjukdomen kunde bromsas och t.o.m. förebyggas. Från att ha varit en sjukdom&lt;br/&gt;&lt;br&gt; med svåra symptom och en medellivslängd på inte ens 20 år lever svenska hemofilipatienter idag ett väsentligen normalt liv, med normal livslängd och livskvalitet. Profylaxbehandling är idag rekommenderad över hela världen som förstahandsval till pojkar med hemofili. Ett stort hinder är dock att kostnaden för sådan behandling är mycket hög och profylax finns därför inte tillgängligt överallt.&lt;br/&gt;&lt;br&gt; FVIII-preparaten som används idag är antingen syntetiska eller framställda från blodplasma från blodgivare. På 1980-talet drabbades en stor del av de blödarsjuka av HIV och/eller gulsot p.g.a. att en del av blodplasman som användes för FVIII-framställning kom från HIV- och/eller gulsotsmittade individer. Katastrofen ledde till att bättre metoder för att rena och avdöda blodprodukter från virus utvecklades och att donerat blod testas mer noggrant. De läkemedel som används idag bedöms vara säkra. En del hemofilipatienter drabbas dock av&lt;br/&gt;&lt;br&gt; biverkningar till FVIII-behandlingen där antikroppsbildning (s.k. inhibitorer), som drabbar ca 30% av patienterna med svår hemofili, är den mest allvarliga. Antikroppar är äggviteämnen som cirkulerar i blodbanan och som där bryter ner effekten av FVIII-läkemedlet. Det leder till att patienterna på nytt löper en stor blödningsrisk, både spontant och t.ex. vid kirurgiska ingrepp eller olyckor. Blödningar hos patienter med FVIII-inhibitorer är ofta svårbehandlade. Det finns&lt;br/&gt;&lt;br&gt; idag läkemedelsalternativ till FVIII som kan ges till dessa patienter och de preparaten kallas för by-passing-produkter. När man behandlar patienter med FVIII kan man efter injektionen mäta den farmakologiska effekten i blodet. För by-passing-produkter finns inte någon metod&lt;br/&gt;&lt;br&gt; tillgänglig i kliniken för att mäta effekten. Den kliniska erfarenheten av bypassing-behandling är att effekten kan variera mellan olika individer och därför är det önskvärt att finna en metod för att vägleda val av dosering och även i viss mån val av specifik by-passing-produkt. Ett annat problem med by-passing-behandling&lt;br/&gt;&lt;br&gt; är att kostnaden per injektion är betydligt högre än FVIII-behandling.&lt;br/&gt;&lt;br&gt; I två av de delarbeten som diskuteras i den här avhandlingen har by-passingbehandling vid svår hemofili A utvärderats med hjälp av en metod som kallas för ”thrombin generation assay” (TGA). Metoden presenterades första gången i mitten av 1980-talet och har sedan dess utvecklats och modifierats. Med TGA kan man mäta den sammanlagda blodlevringsförmågan i blodplasma från en individ, till skillnad från t.ex. FVIII-mätning där man endast mäter halten av just FVIII. På så&lt;br/&gt;&lt;br&gt; sätt får man en mer fullständig bild av blodlevringsförmågan.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I det första delarbetet (Paper I) var frågeställningen om by passingbehandling av patienter med hemofili påverkas av ärftliga faktorer. Blodplasma från brödrapar med hemofili blandades med två olika by-passing-produkter i två separata försök och analyserades med TGA. Resultaten visade att blodlevringsförmågan inom ett brödrapar når jämförbara nivåer vid tillsats av bypassing-produkter, men att två obesläktade individer varierar betydligt mer i blodlevringsförmåga vid by-passing-behandling. Resultaten indikerar att det kan finnas en ärftlig faktor som styr hur väl vår koagulation fungerar. Inom hemofilisjukvården skulle man kunna använda sig av kunskapen om hur en familjemedlem har svarat på behandling med by-passingprodukt om ytterligare en individ inom samma familj behöver liknande behandling. För att säkert veta detta behöver man dock utvärdera effekten i större patientmaterial.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I det andra delarbetet (Paper II) användes TGA för att utvärdera&lt;br/&gt;&lt;br&gt; behandlingseffekten av en kombination av by-passing-behandling och FVIII. Det har tidigare observerats hos patienter med inhibitorer att de, trots närvaro av de FVIII-hämmande antikropparna, blöder mindre om de behandlas med FVIII. Hypotesen i delarbete två var därför att tillsats av FVIII eventuellt kan förstärka effekten av by-passing-produkten. Flera olika FVIII-produkter testades som tillägg till två olika by-passing-produkter. Resultaten från försöken visade att tillägget av FVIII gav en förstärkt, additiv, effekt på blodlevringsförmågan mätt med TGA(additiv: effekten av läkemedel 1 + effekten av läkemedel 2 = dubbel effekt; jfr 1+1=2). I vissa fall var effekten t.o.m. synergistisk, vilket innebär att tillsatsen av FVIII gav en extra skjuts till blodlevringen utöver den uppmätta additiva effekten (jfr. 1+1&amp;gt;2). Resultaten talar för att denna strategi skulle kunna användas för behandling hos i alla fall patienter med svåra blödningar där endast by-passingprodukt inte ger tillräcklig effekt.&lt;br/&gt;&lt;br&gt; Hämmande antikroppar mot FVIII (inhibitorer) mäts med en särskild metod som kallas för Bethesda-metod. Den metoden kan dock inte upptäcka alla sorters antikroppar. Man vet sedan tidigare att det bildas olika sorters FVIII-antikroppar i kroppen, både hos hemofilipatienter, men också hos friska individer. Vilken funktion eller effekt dessa antikroppar har på FVIII är oklart. Vissa studier har visat att de kan inverka negativt på effekten av FVIII-läkemedel, medan andra studier har visat att så inte är fallet. I delarbete III-V användes en metod som kallas för ELISA för att hitta FVIII-antikroppar i blodplasma från patienter med hemofili. Två stora patientgrupper undersöktes; en grupp av bröder med hemofili (n=201) och en grupp med obesläktade individer med hemofili (n=78). En&lt;br/&gt;&lt;br&gt; frågeställning i båda studierna var om olika typer av FVIII-produkter kan påverka bildandet av FVIII-antikroppar på olika sätt och i olika grad. Därför testades plasmaproverna mot tre olika FVIII-produkter som är vanliga vid behandling av hemofili. Resultaten visar att ca 19% av bröderna och ca 13% av de obesläktade individerna bildar FVIII-antikroppar och att fynden av FVIII-antikroppar varierar beroende av vilken FVIII-produkt som används i experimenten. Teoretiskt kan man tänka sig att en individ bara producerar antikroppar mot just den produkt de själva använt, men något tydligt sådant mönster fann vi inte i studierna. I brödrastudien ingick ett antal individer som genomgått behandling syftande till att oskadliggöra inhibitoriska FVIII-antikroppar (ITI) och när prover från dessa individer analyserades fann vi att ca 25% av dem hade kvarstående FVIIIantikroppar, men av annan typ än de hämmande antikropparna. Vi fann också att en grupp patienter som hade drabbats av inhibitorer tidigare hade blivit av med dessa spontant utan aktiv ITI. Detta fynd är intressant då ITI-behandling är tidskrävande, omfattande för patienten och mycket kostsam. Om man bättre kan välja ut patienter som verkligen behöver den skulle mycket vara vunnet. Den obesläktade patientgruppen följdes över en tidsperiod av ca fyra år och&lt;br/&gt;&lt;br&gt; flera blodprover insamlades under den tiden. Analys av proverna visade att produktionen av FVIII-antikroppar varierade över tiden på så sätt att en individ uppvisade ett positivt svar vid ett provtagningstillfälle för att sedan inte producera några antikroppar vid nästa provtagningstillfälle. Flera, redan kända, riskfaktorer&lt;br/&gt;&lt;br&gt; för bildande av inhibitoriska FVIII-antikroppar (t.ex. FVIII-mutation, ålder, kirurgiskt ingrepp och gulsotinfektion) utvärderades i relation till FVIIIantikroppsutfallet utan att vi fann någon koppling till dessa riskfaktorer. mycket intressant fynd i långtidsobservationen av obesläktade individer var att patienter som någon gång under studietiden bildade FVIII-antikroppar blödde&lt;br/&gt;&lt;br&gt; signifikant mindre än den grupp av patienter som inte bildade några antikroppar. Orsaken till detta fynd är ännu oklar, men kan indikera att det kan finnas en typ av FVIII-antikroppar som skyddar eller t.o.m. förstärker FVIII-effekten i blodet. Framtida studier får utvisa.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/35fffb9e-8176-4862-885b-a7136de25d5e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Jenny_Klintman_Thesis_2013.pdf">https://portal.research.lu.se/files/3330424/3626194.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3775954</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>hemophilia A</topic> <topic>inhibitors</topic> <topic>non-neutralizing anti-FVIII antibodies</topic> <topic>thrombin generation assay</topic> <topic>ELISA</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-97-5</identifier> <identifier type="oldLupId">3626179</identifier> <part> <detail type="volume"> <number>2013:28</number> </detail> <extent unit="pages"> <total>164</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-03-20T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>35fffb9e-8176-4862-885b-a7136de25d5e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:05+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:05+02:00</recordDateApproved> </recordInfo> </mods>

FTD encompasses the behavioural variant (bvFTD) and the progressive&lt;br/&gt;&lt;br&gt; aphasias: progressive non-fluent aphasia (PNFA) and semantic dementia (SD). Neuropathological classification is based on&lt;br/&gt;&lt;br&gt; protein pathology with three major subgroups: Tau, TDP-43 and FUS. Early clinical diagnosis is challenging and prediction of&lt;br/&gt;&lt;br&gt; neuropathological subtype is often not possible.&lt;br/&gt;&lt;br&gt; The objective was to identify clinical markers (biomarkers or specific symptoms), of possible diagnostic value. In paper I&lt;br/&gt;&lt;br&gt; potential cerebrospinal fluid biomarkers were examined. Increased neurofilament light protein (NFL) was seen in FTD&lt;br/&gt;&lt;br&gt; compared to Alzheimer’s disease and healthy controls, particularly in the clinical subtype SD and in tau-negative cases. In&lt;br/&gt;&lt;br&gt; paper II clinical and neuropathological characteristics in a large bvFTD family with a newly identified mutation (C9ORF72&lt;br/&gt;&lt;br&gt; expansion) were analysed. Despite age variations at onset and duration, symptomatology was strikingly homogenous.&lt;br/&gt;&lt;br&gt; Unexpectedly, psychotic symptoms and extensive somatic complaints, not included in current FTD criteria, were common.&lt;br/&gt;&lt;br&gt; These symptoms were further analysed in an extended neuropathologically verified cohort (paper III, IV) and both symptom&lt;br/&gt;&lt;br&gt; categories were found in about 1/3 of all cases. There was no clear correlation with protein pathology. Psychotic symptoms&lt;br/&gt;&lt;br&gt; correlated strongly with right-predominant brain pathology. Clinical misdiagnosis, often psychiatric, was especially common&lt;br/&gt;&lt;br&gt; among young patients and in those with psychotic symptoms. Our findings highlight the clinical importance of recognizing&lt;br/&gt;&lt;br&gt; symptoms not included in current criteria to achieve a better understanding of these phenomena and to improve diagnostics.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Frontotemporal demens (FTD) är en grupp av demenssjukdomar som främst drabbar&lt;br/&gt;&lt;br&gt; hjärnans pannlober och främre tinninglober. Gemensamt för FTD-sjukdomarna är en&lt;br/&gt;&lt;br&gt; fortskridande nervcellsförlust och förtvining av framför allt hjärnbarken. Sjukdomen&lt;br/&gt;&lt;br&gt; medför personlighetsförändring med beteendestörningar, förändringar i känsloliv och&lt;br/&gt;&lt;br&gt; kognitiva svårigheter. En försämring av språk och talförmåga samt motoriska&lt;br/&gt;&lt;br&gt; symptom är också vanligt förekommande.&lt;br/&gt;&lt;br&gt; Hos yngre som drabbas av demenssjukdom (&amp;lt;65 år) utgör FTD uppemot 20 % och&lt;br/&gt;&lt;br&gt; är näst Alzheimers sjukdom den vanligaste demenssjukdomen. Sjukdomen börjar&lt;br/&gt;&lt;br&gt; smygande, oftast i 50-60 års ålder, men debut både så tidigt som i 30-40 års ålder&lt;br/&gt;&lt;br&gt; eller över 80 år förekommer. Överlevnad från symptomdebut är oftast 8-10 år, men&lt;br/&gt;&lt;br&gt; kan variera mellan 2 och 25 år. Orsakerna till FTD-sjukdomarna är fortfarande&lt;br/&gt;&lt;br&gt; ofullständigt kända, diagnosen är svår att ställa och den diagnostiska förseningen kan&lt;br/&gt;&lt;br&gt; vara flera år.&lt;br/&gt;&lt;br&gt; Beroende på vilka symptom som är mest framträdande kan FTD delas in i flera&lt;br/&gt;&lt;br&gt; varianter; beteendevariant (bvFTD), två språkvarianter som kallas progressiv ickeflytande&lt;br/&gt;&lt;br&gt; afasi (PNFA) respektive semantisk demens (SD) samt FTD med&lt;br/&gt;&lt;br&gt; motorneuronsjukdom/amyotrofisk lateralskleros (FTD-ALS). Nya forskningsfynd&lt;br/&gt;&lt;br&gt; inkluderar även de båda Parkinsonliknande sjukdomarna progressiv supranukleär&lt;br/&gt;&lt;br&gt; pares (PSP) och corticobasal degeneration (CBD). Fortfarande föreligger stora&lt;br/&gt;&lt;br&gt; svårigheter att utifrån den kliniska bilden förutsäga vilka underliggande&lt;br/&gt;&lt;br&gt; hjärnförändringar som ligger bakom hos den enskilde individen. Hos majoriteten av&lt;br/&gt;&lt;br&gt; FTD-patienterna återfinns ett av tre hittills identifierade sjukliga proteiner och dessa&lt;br/&gt;&lt;br&gt; ligger numera till grund för den neuropatologiska diagnostiken; Tau, TDP-43 (TAR&lt;br/&gt;&lt;br&gt; DNA-binding protein 43) eller FUS (fused in sarcoma). Inom såväl den tau-positiva&lt;br/&gt;&lt;br&gt; som den TDP-43 positiva gruppen finns ytterligare undergrupper.&lt;br/&gt;&lt;br&gt; Ärftlighet för liknande demenssjukdom förekommer hos ca 30-50% av patienterna.&lt;br/&gt;&lt;br&gt; Hos en del patienter kan man påvisa en av flera genetiska mutationer. En nyligen&lt;br/&gt;&lt;br&gt; upptäckt förändring på kromosom 9 (C9ORF72) har visat sig vara den vanligaste&lt;br/&gt;&lt;br&gt; genetiska orsaken till FTD i Skandinavien.&lt;br/&gt;&lt;br&gt; 47&lt;br/&gt;&lt;br&gt; Hög förekomst av psykiska sjukdomar (såsom schizofreni) har noterats hos släktingar&lt;br/&gt;&lt;br&gt; till patienter med FTD men mer forskning behövs för att verifiera dessa fynd.&lt;br/&gt;&lt;br&gt; I nuläget finns ingen botande eller bromsande behandling. En förutsättning för att&lt;br/&gt;&lt;br&gt; kunna utveckla verksamma behandlingar är dels att ställa korrekt diagnos i tidigt&lt;br/&gt;&lt;br&gt; sjukdomsskede samt att hitta markörer för vilka hjärnförändringar som föreligger. En&lt;br/&gt;&lt;br&gt; sådan sjukdomsmarkör skulle t ex kunna vara ett protein som kan mätas i blod eller&lt;br/&gt;&lt;br&gt; ryggvätska.&lt;br/&gt;&lt;br&gt; Min doktorsavhandling fokuserar dels på bakomliggande faktorers betydelse för&lt;br/&gt;&lt;br&gt; uppkomst av FTD, dels studier av kliniska kännetecken och sjukdomsmarkörer som&lt;br/&gt;&lt;br&gt; kan förbättra diagnostik och ha betydelse för vård och behandling.&lt;br/&gt;&lt;br&gt; I studie I fann vi att proteinet neurofilament light (NFL) i ryggvätskan var förhöjt vid&lt;br/&gt;&lt;br&gt; FTD jämfört med friska kontroller och patienter med Alzheimers sjukdom. Nivån av&lt;br/&gt;&lt;br&gt; NFL var högst i den kliniska undergruppen SD. Vid neuropatologiskt verifierad FTD&lt;br/&gt;&lt;br&gt; fann vi högst NFL-nivåer i de fall där vi inte kunde påvisa sjuklig ansamling av&lt;br/&gt;&lt;br&gt; proteinet tau i hjärnan.&lt;br/&gt;&lt;br&gt; Kliniska symptom och neuropatologiska fynd studerades i tre generationer i en stor&lt;br/&gt;&lt;br&gt; familj med bvFTD där C9ORF72 identifierats (studie II). Vi fann en överraskande&lt;br/&gt;&lt;br&gt; hög förekomst av psykotiska symptom och smärtproblematik (icke typiska&lt;br/&gt;&lt;br&gt; demenssymptom). Den neuropatologiska undersökningen visade att patienterna hade&lt;br/&gt;&lt;br&gt; det sjukliga proteinet TDP-43 i hjärnan.&lt;br/&gt;&lt;br&gt; De oväntade resultaten med hög förekomst av såväl smärtproblematik som psykotiska&lt;br/&gt;&lt;br&gt; symptom motiverade till fortsatta studier av dessa specifika symptom hos ett större&lt;br/&gt;&lt;br&gt; antal patienter.&lt;br/&gt;&lt;br&gt; I arbete III och IV analyserades kliniska journaler och hjärnmaterial från 97&lt;br/&gt;&lt;br&gt; demenspatienter som under livet följts på Psykogeriatriska kliniken i Lund&lt;br/&gt;&lt;br&gt; (nuvarande Minneskliniken) och som vid neuropatologisk undersökning på&lt;br/&gt;&lt;br&gt; Neuropatologen i Lund under åren 1969-2013 påvisats ha FTD-förändringar i&lt;br/&gt;&lt;br&gt; hjärnan.&lt;br/&gt;&lt;br&gt; Vi fann att genomsnittlig ålder vid insjuknandet var 58 år. 93% insjuknade före 70&lt;br/&gt;&lt;br&gt; års ålder. Sjukdomsdurationen varierade mellan 1 och 28 år, men var i genomsnitt 8&lt;br/&gt;&lt;br&gt; år. Vi fann ingen könsskillnad. Ärftlighet för liknande demenssjukdom förelåg hos&lt;br/&gt;&lt;br&gt; 40%.&lt;br/&gt;&lt;br&gt; Arbete III fokuserade på kroppsliga klagomål (smärta, bl. a. från mage och tarm,&lt;br/&gt;&lt;br&gt; muskler/skelett, huvudvärk/migrän) samt avvikande smärtreaktion (överdriven eller&lt;br/&gt;&lt;br&gt; utebliven smärtreaktion). Vi fann att långvarig smärtproblematik, utan medicinsk&lt;br/&gt;&lt;br&gt; påvisbar orsak, eller avvikande smärtreaktion förelåg hos ca 40% av patienterna. Ingen&lt;br/&gt;&lt;br&gt; säker koppling till förändringar i specifika hjärnområden eller någon viss&lt;br/&gt;&lt;br&gt; proteinpatologi kunde identifieras.&lt;br/&gt;&lt;br&gt; 48&lt;br/&gt;&lt;br&gt; I arbete IV studerades förekomsten av psykotiska symptom och dess eventuella&lt;br/&gt;&lt;br&gt; relation till specifika hjärnförändringar. Psykotiska symptom (hallucinationer,&lt;br/&gt;&lt;br&gt; vanföreställningar, eller paranoia) förekom någon gång under sjukdomsförloppet hos&lt;br/&gt;&lt;br&gt; cirka 1/3 av alla patienter och fanns hos patienter inom alla proteinpatologiska&lt;br/&gt;&lt;br&gt; undergrupper. Allra vanligast var det hos patienter med proteinet FUS eller hos de&lt;br/&gt;&lt;br&gt; patienter där vi inte kunde hitta något specifikt protein. Vi fann en stark koppling&lt;br/&gt;&lt;br&gt; mellan psykotiska symtom och högersidiga hjärnförändringar. I samma studie såg vi&lt;br/&gt;&lt;br&gt; att yngre patienter initialt fick andra diagnoser än FTD, oftast depression eller psykos,&lt;br/&gt;&lt;br&gt; i betydligt högre utsträckning än äldre patienter. 42% av alla FTD patienter fick&lt;br/&gt;&lt;br&gt; initialt en psykiatrisk diagnos och 34% en annan demensdiagnos. Senare i förloppet&lt;br/&gt;&lt;br&gt; fick dock majoriteten korrekt diagnos, men det dröjde i genomsnitt 4 år från de första&lt;br/&gt;&lt;br&gt; sjukdomssymptomen.&lt;br/&gt;&lt;br&gt; Longitudinella studier där man under sjukdomsförloppet fokuserar på olika symptom&lt;br/&gt;&lt;br&gt; och markörer samt i uppföljning även korrelerar dessa fynd till sjukliga förändringar i&lt;br/&gt;&lt;br&gt; hjärnan ökar vår möjlighet att ställa rätt diagnos tidigt och kan i förlängningen bidra&lt;br/&gt;&lt;br&gt; till att finna behandlingsmetoder.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4380e8dc-409b-488a-a9e6-b14c8b135ab0</url> </location> </relatedItem> <originInfo> <publisher>Department of Psychogeriatrics, Department of Clinical Sciences</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>genetics</topic> <topic>neuropsychiatric symptoms</topic> <topic>protein pathology</topic> <topic>clinical diagnosis</topic> <topic>neuropathology</topic> <topic>biomarkers</topic> <topic>Frontotemporal dementia</topic> </subject> <subject authority="lup"> <topic>Geriatrics</topic> <topic>Psychiatry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-063-0</identifier> <identifier type="oldLupId">4777598</identifier> <part> <detail type="volume"> <number>2014:134</number> </detail> <extent unit="pages"> <total>120</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-12-06T09:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Contact allergy to metal ions eluted from stainless steel stents has been suggested to contribute to in-stent restenosis. Studies have reported a higher rate of restenosis with gold-plated stents, but the correlation to contact allergy was not evaluated. Nickel is the most common contact allergen known, with a median prevalence of 8.5% in North America and Western Europe. Contact allergy to gold has been demonstrated by patch testing with various gold salts and with the metal itself. The patients included in the study had received one type of stent manufactured from stainless steel but differing in that one was electroplated with gold. &lt;br/&gt;&lt;br&gt; The result of this work show that contact allergy to gold is more common in a stented population than in a control population. Dental gold, ear piercing and age were all found to be independent risk factors for contact allergy to gold. However, the possibility of sensitization due to the gold-plated stent remains. Statistical analysis suggests the induction of contact allergy to gold due to the gold-plated stent implanted in the coronary vessel. Allergy to Myroxylon pereirae (a wood extract used in dental cement, as fragrance in cosmetics, creams, ointments and as flavouring) and caine mix (three anaesthetics for topical use), was also more common in the stented population than in controls, indicating the importance of the oral mucosa for sensitization. A correlation was found between gold-plated stents, contact allergy to gold and an increased frequency of restenosis. The gold concentration in blood (B-Au) was 5 times higher in gold-stented patients than in Ni-stented patients. The patch test reactions for gold were also correlated to B-Au: the higher the B-Au, the stronger the patch test reaction and the lower the concentration eliciting a positive patch test. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, the results indicate that implantation of a gold-plated stent in the coronary vessel induces gold allergy, and that contact allergy could be a risk factor in the restenosis process. The findings underline the importance of careful evaluation of new products, routines and materials with regard to the risk of sensitization and/or elicit an allergic reaction to a contact allergen. The gold concentration in blood was shown to correlate with the result of patch tests, which indicates that systemic exposure to an allergen, at least in the case of gold, causes skin reactivity to gold following topical exposure.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; I det här arbetet studerades kontaktallergi för metaller som finns i olika stentar. Patienterna som ingick i studien hade blivit stentade med olika typer av stentar. En av stentarna var gjord av rostfritt stål (nickelstent) och den andra var förgylld (guldstent). Resultaten av lapptestningen visade att patienterna hade en hög frekvens av både guld- och nickelallergi, och att man inte kunde utesluta att metallerna i stentarna hade bidragit till att patienterna fått sin kontaktallergi. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De stentade patienterna jämfördes också med en kontrollgrupp bestående av patienter som sökt för misstänkt kontaktallergi vid vår klinik. I den jämförelsen undersöktes inte bara kontaktallergier för metaller utan även andra kända kontaktallergen. Resultatet visade att kontaktallergi för ett ämne som används i parfym och smaksättning (Myroxylon pereirae) samt lokalbedövningsmedel (kain mix) var betydligt vanligare hos de stentade patienterna jämfört med kontrollgruppen. Myroxylone pereirae används bland annat i en tandcement och de stentade patienterna hade mycket guld i munnen. Förekomsten av dentalguld kan betyda att patienterna fått gjort större dentalarbeten och på så sätt fått sin kontaktallergi för Myroxylone pereirae via tandcementen. En förklaring till kontaktallergin för kain mix kan vara att de stentade patienterna fått lokalbedövningsmedel i samband med sin stentning. &lt;br/&gt;&lt;br&gt; Det har framkommit i andra studier att patienter som behandlats med en guldstent har drabbats av fler restenoser än patienter som behandlats med andra stentar. Kontaktallergi har diskuterats kunna vara en bidragande orsak. Vi undersökte därför också restenosfrekvensen hos de stentade patienterna och fann att patienter med en guldstent hade fler restenoser jämfört med patienter med en nickelstent. Vi fann också ett samband mellan guldstent, kontaktallergi för guld och ett ökat antal restenoser. Vi kunde inte se något motsvarande samband mellan nickelstent, kontaktallergi för nickel och restenos. Guldstentar används inte mer idag p.g.a. rapporterna om en ökad restenosrisk men dagens stentar innehåller andra kända metaller som eventuellt kan ge en kontaktallergisk reaktion. &lt;br/&gt;&lt;br&gt; Det här arbetet understryker vikten av en noggrann utvärdering av nya produkter, rutiner och material med hänsyn till riskerna för att ge en kontaktallergisk reaktion samt möjligheten för att orsaka en ny kontaktallergi.&lt;br/&gt;&lt;br&gt; Vi undersökte också patienternas guld- och nickelhalt i blodet. Resultatet visade att patienter med en guldstent hade en högre guldhalt i blodet jämfört med patienterna med en nickelstent. Vi såg också att ju högre guldhalt i blodet patienterna hade, desto starkare kontaktallergi uppvisade de. För att undersöka det vidare gjorde vi en experimentell studie som också visade på ett liknande samband. Resultaten indikerar att ett kontaktallergens koncentration i blodet, i alla fall för guld, har betydelse för hudens reaktion i kontakt med guld. Om resultaten blir bekräftade med fler studier och med andra kontaktallergen kan det innebära en förändring i behandling och förebyggande arbete mot allergiskt kontakt eksem då även ett allergens koncentration i blodet måste tas i beaktande.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7b92647c-a00f-44b2-bf6b-4c7a345f7d80</url> </location> </relatedItem> <originInfo> <publisher>Department of Occupational and Environmental Dermatolog, Deparment of Dermatology, Malmö University Hospital</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>B-Au</topic> <topic>patch testing</topic> <topic>restenosis</topic> <topic>contact allergy</topic> <topic>Dermatology</topic> <topic>metals</topic> <topic>gold</topic> <topic>stent</topic> <topic>B-Ni</topic> <topic>nickel</topic> </subject> <subject authority="lup"> <topic>Occupational Health and Environmental Health</topic> <topic>Dermatology and Venereal Diseases</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-46-0</identifier> <identifier type="oldLupId">1243747</identifier> <part> <detail type="volume"> <number>2008:93</number> </detail> <extent unit="pages"> <total>146</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-11-07T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>7b92647c-a00f-44b2-bf6b-4c7a345f7d80</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:13+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:13+02:00</recordDateApproved> </recordInfo> </mods>

The molecular background of how these genes participate in carcinogenesis is not fully understood. CYLD is a deubiquitinating enzyme known to specifically target lysine 63 linked ubiquitin chains, which can negatively regulate the BCL-3, NF-κB and JNK signaling pathways, leading to a decrease of cell survival or proliferation. BCL-3 is an alternative IκB family member that is needed for activation (or repression) of target genes by homodimeric p50 and p52. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The aim of this thesis was to further investigate the molecular mechanisms behind CYLD and BCL-3 regulation and how they might contribute to carcinogenesis. In particular, the role of BCL-3 in prostate cancer (PCa), and the role of CYLD in hepatocellular carcinoma (HCC) were studied.&lt;br/&gt;&lt;br&gt; In PCa we found up-regulation of BCL-3 in human prostate cancers with abundant infiltration of inflammatory cells. Using PCa cell lines we found that interleukin-6 (IL-6) could activate STAT3 mediated up-regulation of BCL-3, which in turn could elevate Id-1 and Id-2 expression. Knockdown of BCL-3 increased the sensitivity for anticancer drug-induced apoptosis. PCa cells with reduced BCL-3 levels that were subcutaneously injected into NUDE mice formed smaller tumors due to a higher percentage of apoptotic cells. &lt;br/&gt;&lt;br&gt; In other tissues Bcl-3 has been shown to regulate proliferation through expression of its target gene CYCLIN D1, a process that is negatively regulated by CYLD. We found that CYLD knockout MEF cells have significantly increased proliferation rates and increased levels of CYCLIND1 in a serum dependent manner when compared with wild type MEF cells. The reduced proliferation in wild type cells was mediated through up-regulation of CYLD by transcription factor serum response factor (SRF) in a p38 mitogen-activated protein kinase (p38MAPK) dependent manner. Knockdown of SRF by siRNA or inhibition of p38MAPK reduced the expression of CYLD and increased cell proliferation rate. These results suggest that SRF is a positive regulator of CYLD expression, which in turn reduces the mitogenic activation of wild type MEF cells. &lt;br/&gt;&lt;br&gt; For further investigation of the molecular mechanisms of CYLD in cancer we performed a tissue microarray, comparing benign liver tissue with HCC. We found that CYLD is significantly down-regulated in human (HCC) and that CYLD expression was inversely correlated with the expression of proliferation marker Ki67. In vivo experiments showed that CYLD deficient mice were more susceptible to the chemical carcinogen DEN-induced HCC. Furthermore, HCC isolated from CYLD knockout mice had elevated cell proliferation compared to wild type mice. This effect was mediated via TRAF-2 ubiquitination, JNK activation and c-MYC expression. In correlation to this result, transient transfection of CYLD into a HCC cell line restricted cell proliferation and reduced the activation of JNK. Together these results suggest that CYLD down-regulation is a risk factor for development and progression of HCC mediated through activation of JNK1</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2d137c7a-9526-4044-8820-db470d9f2b46</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kristofer_Ahlqvist_Thesis_Without_Papers.pdf">https://portal.research.lu.se/files/3331253/3049768.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1061298</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Molecular tumor Pathology</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-23-4</identifier> <identifier type="oldLupId">3049764</identifier> <part> <detail type="volume"> <number>2012:60</number> </detail> <extent unit="pages"> <total>62</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-09-27T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>2d137c7a-9526-4044-8820-db470d9f2b46</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:14+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:14+02:00</recordDateApproved> </recordInfo> </mods>

They act as a supporting structure but can also significantly influence cellular behavior in development, tissue homeostasis and disease. Laminins, a major BM component, are multidomain proteins, consisting of three polypeptide chains (α, β and γ). During pregastrulation development, stem cells convert and epithelial tissues are formed. This process is faithfully mimicked in vitro by embryoid body (EB) cultures. Fibroblast growth factor (FGF) signaling is crucial when the step-like process of EB development is initiated with the formation of an endoderm. A subendodermal BM is formed, in which the globular domains LG4-5 of the laminin α1 chain (α1LG4-5) are responsible for the induction of the epiblast &lt;br/&gt;&lt;br&gt; EBs derived form embryonic stem (ES) cells, modified to repress FGF receptor signaling, have been described before. However, a full-scale analysis of the transcriptome was missing. We therefore analysed these EBs at four time points during differentiation by the use of microarray technique. An extensive catalogue of affected genes was reported. A majority of the genes directed by FGF signalling were encoding BM and endodermal proteins. In addition, we also analysed the expression profile of wild type EBs. In both these studies, we found interesting genes not previously described in early development or identified as FGF targets. Hopefully, our gene catalogue will be a valuable source for the scientific community interested in FGF signaling, developmental biology and stem cell research. Furthermore, a gene expression study was set up to get a better insight of epiblast inducement by α1LG4-5. EBs derived form ES cells with a targeted deletion of the α1LG4-5 domains were analysed. To our surprise, we found several indications of an incomplete differentiation of the visceral endoderm. We therefore hypothesize a novel autocrine mechanism for α1LG4-5 in regulating the developing endoderm. &lt;br/&gt;&lt;br&gt; We also suggest novel roles for laminin LG4-5 in the neuromuscular system. Using laminin α2 chain deficient mice overexpressing laminin α1 chain lacking the LG4-5 domains, we show that these domains, and consequently binding to the receptor dystroglycan are not crucial in diaphragm and heart, but essential in the peripheral nervous system.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4182e91f-9245-4ffa-967b-e108fb090e97</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="elektron_spikning_kappa_.pdf">https://portal.research.lu.se/files/3331778/1480394.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">415680</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>muscular dystrophy</topic> <topic>development</topic> <topic>Basement membrane</topic> <topic>laminin</topic> <topic>stem cells</topic> <topic>FGF</topic> </subject> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-81-3</identifier> <identifier type="oldLupId">1480341</identifier> <part> <detail type="volume"> <number>2009:92</number> </detail> <extent unit="pages"> <total>155</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-01-13T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>4182e91f-9245-4ffa-967b-e108fb090e97</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:19+02:00</recordDateApproved> </recordInfo> </mods>

Degeneration of neurons in specific regions of the brain, formation of senile plaques and neurofibrillary changes are some of the neuropathological features of the disease. As a result of the degenerating process a deficiency in cholinergic function occurs in AD. This has been a target for therapy since the cholinesterase inhibitors (ChEIs) (tacrine, donepezil, rivastigmine, galantamine) were introduced as treatments for AD. Multiple short-term randomised clinical trials of ChEI treatment show beneficial effects on cognition, global functioning and activities of daily living in AD. Whether the effects of long-term ChEI treatment in a routine clinical setting are equally positive remains to be investigated. In the present study patients from naturalistic settings were investigated in long-term treatment studies (tacrine-study and The Swedish Alzheimer Treatment Study, SATS). Patients were repeatedly assessed with cognitive scales and global ratings over 3-5 years. A positive response to treatment was described in different response models. At 6 months 3/4 of the patients and at 3 years 1/3 were better or unchanged. Treatment for more than a year and positive response to tacrine treatment delayed nursing-home placement but did not influence survival. CSF T-tau and P-tau were possible markers for disease severity and P-tau for the abundance of symptoms in AD. A fast pre-treatment progression rate was a positive predictor for response to ChEI treatment even after adjusting for disease severity, another positive predictor of response. Baseline factors such as age, gender, CSF biomarkers and APOE genotype did not predict response to treatment. Dropout in these naturalistic settings was lower than expected. ChEI treatment changed the progression of the disease for more than 6 months and stabilised groups of patients for even longer</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9ee48eb1-c21e-49ae-995a-27807113361f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="AW_Kappa_080513_for_tryck.pdf">https://portal.research.lu.se/files/3332989/1150246.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2695893</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>treatment response</topic> <topic>cholinesterase inhibitor</topic> <topic>CSF-biomarkers</topic> <topic>pre-treatment progression</topic> <topic>predictors</topic> <topic>Alzheimer’s disease</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-26-2</identifier> <identifier type="oldLupId">1150245</identifier> <part> <detail type="volume"> <number>2008:73</number> </detail> <extent unit="pages"> <total>157</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-06-05T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>9ee48eb1-c21e-49ae-995a-27807113361f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:35+02:00</recordDateApproved> </recordInfo> </mods>

Most patients with asthma can be controlled with bronchodilators and low to moderate dose inhaled corticosteroids. However, an estimated 5-10% of the population presents a more troublesome disease, often referred to as severe asthma. The aim of present thesis was to study the relationship between histopathological alterations and clinical control in patients with different severities of asthma. To study this, a detailed immunohistochemical analysis was performed on lung biopsies obtained from moderate asthmatics (n = 24 in Paper I), severe asthmatics (n = 25 in Paper II), and uncontrolled severe asthmatics undergoing bronchial thermoplasty treatment (n = 15 and n = 20 in Paper III and IV, respectively). In Paper I, we show that allergic airway inflammation extends to the peripheral airways specifically in patients that are poorly controlled. This suggests that targeting peripheral airway inflammation, for example with extrafine-particle formulations of inhaled corticosteroids, may benefit patients that remain symptomatic despite standard inhaled corticosteroid treatment. In Paper II, we found that symptomatic severe asthma is associated with lower number of eosinophils and no apparent signs of chronic inflammation as compared with stable severe asthma. However, we detected stretches of bronchoepithelial metaplasia in the former patient category suggesting that external assaults, possible episodic pathogen infections, may play an important role in this form of asthma. In Paper III, we show that bronchial thermoplasty markedly improves several elements of clinical control in patients with uncontrolled severe asthma. The clinical improvements were associated with a down-regulation of structures involved in airway narrowing and hyperreactivity, including airway smooth muscle, neuroendocrine epithelial cells, and nerve fibres. In Paper IV, we show that bronchial thermoplasty treatment likewise has long-lasting immunological effects as evident by a reduction of key bronchial immune cells including mast cell populations and T helper cells. These changes may to some extent explain the clinical benefits associated with bronchial thermoplasty, although this remains to be investigated. In summary, the results in this thesis provide new histopathological data that are associated with clinical control in asthma.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5c73ea0d-1c6a-4cac-b194-6a3b9f64d54a</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Bergqvist_web_version.pdf">https://portal.research.lu.se/files/3333376/8831307.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">46793916</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Respiratory Medicine and Allergology, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Severe asthma</topic> <topic>bronchial thermoplasty</topic> <topic>airway smooth muscle</topic> <topic>neuroendocrine cells</topic> <topic>inflammation</topic> <topic>immune cells</topic> <topic>remodelling</topic> </subject> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-221-4</identifier> <identifier type="oldLupId">8169951</identifier> <part> <detail type="volume"> <number>2015:141</number> </detail> <extent unit="pages"> <total>70</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-12-17T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>5c73ea0d-1c6a-4cac-b194-6a3b9f64d54a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:41+02:00</recordDateApproved> </recordInfo> </mods>

This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper I analyses the performance degradation of dynamic nonlinearity in the feedback DAC of the DSM, caused by Vth mismatch in the current-switching (differential) pair of a current-steering DAC. A model is developed to study return-to-zero (RZ) and non-return-to-zero (NRZ) feedback DACs, with and without data-weighted averaging (DWA), where an RZ DAC with DWA recovers the performance.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper II and III presents a feedback scheme for improved robustness against variations in loop delay. An RZ pulse, centered in the clock period, is used in the innermost feedback path which has the highest sensitivity to loop delay, while NRZ pulses are adopted in the outer feedback paths to reduce the sensitivity to clock jitter and lower the integrator slew rate requirements. Furthermore, the otherwise obligatory loop delay compensation path (e.g. an additional DAC and adder) could be omitted to reduce hardware complexity. A discrete-time model of the feedback scheme confirms a negligible loss in performance. The 3rd-order CT DSM in 65nm CMOS with 9MHz LTE bandwidth achieves 69/71dB SNDR/SNR and consumes 7.5mW from a 1.2V supply. Measurements with OFDM signals verify an improved tolerance to blockers outside the signal band of the DSM.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper IV and V present two filtering ADCs, where the DSM is merged into the channel select filter to suppress the noise from the DSM. The first and second prototypes provide a 2nd- and 3rd-order channel select filtering and improve the SNDR of the DSM by 14dB and 20dB, respectively, which in theory can be exploited to reduce the DSM power consumption by four to eight times.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The first prototype has a 288MHz clock frequency, a 9MHz LTE bandwidth, a 2nd-order Butterworth filter response with 12dB gain, an input-referred noise of 8.1nV/sqrt(Hz), an in/out-of-band IIP3 of 11.5/27dBVrms, and a power consumption of 11.3mW. The second prototype is clocked at 576/288MHz with an 18.5/9MHz LTE bandwidth, a Chebyshev filter response with 26dB gain, a low input-referred noise of 5nV/sqrt(Hz), and an in/out-of-band IIP3 of -8.5/20dBVrms, with a power consumption of 7.9/5.4mW for 2xLTE20/LTE20 mode. The prototype was characterized for OFDM modulated blockers and essentially meets the cellular standard LTE Rel. 11. A delay, introduced by the feedback DAC, is compensated by adjusting the filter coefficients to restore the original Chebyshev filter function.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Both prototypes have state-of-the-art power efficiency compared to other filtering ADCs and are comparable or better than a stand-alone filter. Furthermore, the filtering ADC provides both filtering and A/D conversion, which suggests that the A/D conversion is included in a power efficient manner, broadly speaking &quot;for free&quot;.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/840014a8-f65f-44cb-83b4-ded07a3dc327</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Andersson_CTDSM_print.pdf">https://portal.research.lu.se/files/3333980/4302260.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5849862</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Electrical and Information Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>return-to-zero</topic> <topic>A/D converter</topic> <topic>loop delay</topic> <topic>delta-sigma</topic> <topic>ADC</topic> <topic>CMOS</topic> <topic>STF</topic> <topic>continuous-time</topic> <topic>sigma</topic> <topic>delta</topic> <topic>filtering</topic> <topic>CT</topic> <topic>RZ</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Series of licentiate and doctoral dissertations</title> </titleInfo> <identifier type="issn">1654-790X</identifier> <identifier type="isbn">978-91-7473-785-1</identifier> <identifier type="oldLupId">4302214</identifier> <part> <extent unit="pages"> <total>141</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popsciencePopular Science.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3333978/4317559.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-03-21T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>840014a8-f65f-44cb-83b4-ded07a3dc327</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:47+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-24T09:00:14Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:47+02:00</recordDateApproved> </recordInfo> </mods>

The importance of these conventional risk variables is well documented since more than 10 years, and they are used routinely in the clinics. Over the last ten years, cancer research has seen a gradual transition towards personalized medicine, i.e. the exploitation of specific molecular properties in the treatment of tumors. The starting point for personalized medicine is a taxonomy of the tumor type, where genome, transcriptome, and/or proteome data is used to define molecular subtypes that make sense from biological and clinical viewpoints. &lt;br/&gt;&lt;br&gt; The overall aim of the work presented in this thesis is to define the major gene expression subtypes of bladder tumors. The gene expression based subtypes should be viewed as a framework which can be refined either by the integration of genomic, epigenetic, or proteomic data or by the analysis of larger patient cohorts so that the subtypes can be described in greater detail. An exhaustive tumor classification should be based on biological similarity between tumors, and not only group together tumors with similar clinical risk profile. This will increase the probability that the taxonomy is relevant in the evaluation of novel therapies that function by altering pathways or transcriptional programs. In paper 1 we define the two major subtypes of bladder cancer, termed molecular subtype 1 and 2 (MS1 and MS2). In paper 2, MS1 and MS2 are subdivided into five major subtypes named Urobasal A, Urobasal B, Genomically Unstable, SCC-like, and Infiltrated, named after their dominating molecular characteristics. The subtypes were identified in an unsupervised manner and were identified also in external data sets, showing their general applicability. &lt;br/&gt;&lt;br&gt; Secondary to the aim of tumor classification is the evaluation of the potential prognostic value of the described subtypes. To allow for clinical comparisons, tumor classification should be possible using immunohistochemistry (IHC) on archived material. In paper 3 we make use of the same set of tumors as in paper 2 and device a simplified classifier based on IHC and histology. This classifier identifies the five subtypes with the exception of Urobasal B which could not be reliably distinguished from the related Urobasal A subtype. The molecular pathological classifier defined in paper 3 thus has room for improvement and will need to evolve as the true molecular subtypes are refined. &lt;br/&gt;&lt;br&gt; Up to this point we have shown that the subtypes differ in prognosis, but we could not determine whether this was independent of differences observed in stage and grade. In paper 4 we use an independent population based cohort of T1 tumors to retrospectively estimate the prognostic value of the molecular subtypes. The IHC/histology classifier defined in paper 3 is applied, and the molecular subtypes are compared to a current clinical risk stratification model in multivariate analyses. The results show that the subtypes contain as much prognostic information as the current clinical model, and that the best risk stratification is achieved by combining the subtypes with clinical data and an estimate of CD3+ lymphocyte infiltration.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Cancer i urinblåsan är ett stort hälsoproblem i Sverige och världen. Det är den femte vanligaste cancerformen i Sverige och är den som belastar sjukvården med högst kostnader per patient. Ungefär tre fjärdedelar av de drabbade är män och patienterna är oftast kring 60-80 år gamla. Den behandling vi idag kan erbjuda en person som drabbas av blåscancer har inte förändrats på mer än tio år. De framsteg vi har sett inom forskningen kring cancer i andra delar av kroppen i form av nya behandlingsformer, kartläggningar av riskfaktorer och genetiska förändringar har inom blåscancerforskningen varit få. &lt;br/&gt;&lt;br&gt; Det främsta målet för det arbete som presenteras i denna avhandling är att åstadkomma en kartläggninig av de tumörer som uppstår i urinblåsan. Även tumörer som ser likadana ut vid operationstillfället har många mikroskopiska och biokemiska skillnader. Det råder en tro bland cancerforskare att det är dessa skillnader som gör det svårt att hitta effektiva behandlingar mot cancer. Vår hypotes är att en rättfram men avancerad beskrivning av de viktigaste molekylära skillnaderna kan leda till en gruppering av tumörer som kan ha en bättre eller sämre prognos, och därför bör få eller inte få en viss behandling. Det är vår förhoppning att detta klassificeringssystem även kommer vara till stor hjälp för framtida blåscancerforskning. &lt;br/&gt;&lt;br&gt; I det första arbetet lades grunden till klassificeringssystemet. Genom att analysera vilka gener som är aktiva i olika tumörer fann vi två huvudtyper av blåscancer. Den ena typen var mera godartad, medan den andra var mera elakartad. Vi beskrev även i detalj vilka förändringar i arvsmassan som sker i tumörer av de olika typerna. &lt;br/&gt;&lt;br&gt; Det andra arbetet byggde på det första genom att använda samma metodik men inkluderade prov från fler tumörer. På så vis kunde vi göra en förfinad klassificering. Vi kom till slutsatsen att det finns fem subtyper av blåscancer som utvecklar aggressiv tillväxt olika fort och på helt skilda sätt. I detta arbetet visade vi också att många av de läkemedel som testats mot blåscancer riktar sig mot molekyler som endast finns i någon/några av de fem huvudsakliga subtyperna.&lt;br/&gt;&lt;br&gt; I det tredje arbetet försökte vi förbättra och göra vårt klassificeringssystem mera användbart genom att byta metodik. I de två första arbetena användes genuttrycksanalys, som är en förhållandevis dyr och komplicerad analysmetod. I detta tredje arbete användes istället immunhistokemi, d.v.s. infärgning av vävnadssnitt från tumören. Detta ger en delvis förenklad bild av vad vi tidigare observerat, men ger även ny information om subtyperna som vi inte tidigare kände till. Slutligen utarbetade vi en modell för att med den nya, enklare metodiken kunna avgöra vilken av subtyperna en tumör tillhör. Anledningen till att vi bytte metod var dels för att möjliggöra analys av stora historiska biobanker med sparad tumörvävnad, och dels för att underlätta att vårt klassificeringssystem skall kunna användas för diagnostik i dagens sjukvård. &lt;br/&gt;&lt;br&gt; I det sista arbetet tillämpade vi vår subgruppsindelning på 167 fall av stadium T1 blåscancer. Blåscancer i detta stadium är ett problem för sjukvården eftersom de i genomsnitt inte är aggressiva nog för att man skall vilja operera ut hela urinblåsan, men är aggressiva nog för att ibland utvecklas till en dödlig sjukdom. I detta arbetet utredde vi om vår klassificering fungerar bättre eller sämre än de riskfaktorer man använder idag för att avgöra om en tumör är farlig eller ofarlig. Slutsatsen är att både vår indelning och de rådande riskfaktorerna är värdefulla för att avgöra behandling. För att så bra som möjligt kunna avgöra om det är en potentiellt dödlig tumör skall man använda subtypsklassificering tillsammans med rådande riskfaktorer och en bedömning av patientens immunologiska svar mot tumören. &lt;br/&gt;&lt;br&gt; Framöver finns även planer på att tillämpa klassificeringen på tumörer av högre stadium där patienten fått urinblålsan utopererad. Förhoppningen är att indelningen i subtyper hjälper oss utröna vilka patienter som gagnas av kemoterapi och för vilka patienter kemoterapi skulle innebära en överbehandling med onödiga biverkningar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c2613629-a69d-4511-9e02-1e0aee21f4f9</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_Gottfrid_Sjodahl.pdf">https://portal.research.lu.se/files/3334190/4173891.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">914939</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Oncology, Lund</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Bladder cancer</topic> <topic>Subtype</topic> <topic>Classification</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-11-3</identifier> <identifier type="oldLupId">4173874</identifier> <part> <detail type="volume"> <number>2013:136</number> </detail> <extent unit="pages"> <total>122</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-12-12T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>c2613629-a69d-4511-9e02-1e0aee21f4f9</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:50+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:50+02:00</recordDateApproved> </recordInfo> </mods>

When targets are set individually, the resulting incentives may induce inefficient resource allocations, even if agents&apos; motivation is fully in line with the principal&apos;s interests, and performance measures are perfect. Introducing shared targets may improve the incentives to coordinate, especially when agents are highly motivated by activities for which responsibility is not shared, performance measures overestimate the value of these activities, and the imprecision of performance measures is low. Simulations indicate that the one-shot model is a good approximation in the short run when one parameter is initially unknown, but imprecise measures yield substantial deviations from equilibrium when three parameters have to be learned.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The second essay develops a model of costly communication with the weakest-link game as a basis, and boundedly rational agents that choose myopic best replies, have limited information processing capabilities, and may occasionally experiment or make mistakes. Communication may increase efficiency, but as agents face a trade-off between lowering the strategic uncertainty for the group and the costs of communication, the least efficient state is often the unique stochastically stable state. Making communication mandatory on the other hand induces efficient coordination, whereas letting a team leader handle the communication increases efficiency when the leader expects others to follow and has enough authority over the group. Simulations show that the stochastically stable state is also overrepresented in the short run, especially if groups are large.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The third essay examines theoretically and empirically the relationship between budget institutions and fiscal performance in local governments. The model suggests that conflicts of interest over fiscal discipline between the central and the local levels imply that the central level needs institutions that curb the bargaining power and align the incentives of the local levels. A survey covering 265 out of 290 Swedish municipalities is used to collect information on conflicts of interests and budget institutions. The regression results indicate that interactions between institutions and conflicts of interest are important, as the estimated correlations depend on the strength of conflicts. Centralization of the budget process, a credible threat of replacement of managers following systematic deficits, and surplus carry-over rules all appear beneficial to net revenues, but only in municipalities that report substantial conflicts of interest. For municipalities where the conflict is small, a deficit carry-over rule is positively correlated to net revenues.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The fourth essay examines a case in which the Swedish central government provided conditional grants to 36 financially troubled municipalities. The synthetic control method is used to identify suitable comparison units for each of the 36 municipalities. The estimates of fixed effects regressions on the resulting sample indicate that for most of the admitted municipalities, costs seem to be largely unaffected by the program. However, a non-negligible share is able to hold back costs more than expected, and the development of net revenues is favorable for the group as a whole. Thus, participation in a conditional bailout program need not erode fiscal discipline, and may even induce a greater concern for fiscal discipline.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/eb0302e8-3231-4dda-a922-b5d9d2d6f627</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Jens_Dietrichson_dissertation__book_size_.pdf">https://portal.research.lu.se/files/3334228/3735352.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1146611</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Economics, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Organizations</topic> <topic>institutions</topic> <topic>coordination</topic> <topic>incentives</topic> <topic>performance measurement</topic> <topic>communication</topic> <topic>budget processes</topic> <topic>local governments</topic> <topic>fiscal performance</topic> <topic>bailouts</topic> </subject> <subject authority="lup"> <topic>Economics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Economic Studies</title> </titleInfo> <identifier type="issn">0460-0029</identifier> <identifier type="oldLupId">3735351</identifier> <part> <detail type="volume"> <number>171</number> </detail> <extent unit="pages"> <total>223</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-06-14T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>eb0302e8-3231-4dda-a922-b5d9d2d6f627</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:51+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:51+02:00</recordDateApproved> </recordInfo> </mods>

The mortality rate is almost as&lt;br/&gt;&lt;br&gt; high as the incidence with a M/I ratio of 98%, indicating an extremely dismal clinical course. This makes&lt;br/&gt;&lt;br&gt; it imperative to try to develop new therapeutic strategies and to try to identify risk factors in order to intensify&lt;br/&gt;&lt;br&gt; preventive efforts. The most important risk factor for pancreatic cancer is tobacco smoking, but&lt;br/&gt;&lt;br&gt; there are other putative environmental risk factors and some pre-existing diseases that have been linked&lt;br/&gt;&lt;br&gt; to pancreatic cancer. The aim of this thesis is to evaluate different epidemiological aspects in relation to&lt;br/&gt;&lt;br&gt; pancreatic cancer; in more specific terms to investigate the relation between alcohol and pancreatic cancer,&lt;br/&gt;&lt;br&gt; between trypsinogen, pancreatic secretory trypsin inhibitor (PSTI) and pancreatic cancer, between Helicobacter&lt;br/&gt;&lt;br&gt; pylori infection and pancreatic cancer and to investigate if the metabolic syndrome is associated&lt;br/&gt;&lt;br&gt; with the risk of pancreatic cancer.&lt;br/&gt;&lt;br&gt; Results and conclusion: High alcohol intake, estimated using both a questionnaire on attitude towards&lt;br/&gt;&lt;br&gt; alcohol and a laboratory marker in the form of γ-GT is associated with a subsequent high risk of developing&lt;br/&gt;&lt;br&gt; pancreatic cancer. The previously established association between smoking and pancreatic cancer&lt;br/&gt;&lt;br&gt; is confirmed. The hypothesis that pancreatic cancer is related to an imbalance between the trypsinogen&lt;br/&gt;&lt;br&gt; isoforms is in line with the finding concerning the ratio of human anionic trypsinogen and human cationic&lt;br/&gt;&lt;br&gt; trypsinogen (HAT/HCT). There is no overall association between H.pylori infection and the risk of&lt;br/&gt;&lt;br&gt; pancreatic cancer, but H.pylori infection may increase the risk of pancreatic cancer in never smokers and&lt;br/&gt;&lt;br&gt; in low alcohol consumers. High mid-blood pressure, high fasting glucose and the metabolic syndrome as&lt;br/&gt;&lt;br&gt; an entity are associated with an increased risk of pancreatic cancer in women. In men, high mid-blood&lt;br/&gt;&lt;br&gt; pressure is associated with the risk of pancreatic cancer and there is an indication of an association between&lt;br/&gt;&lt;br&gt; high glucose levels and the risk of pancreatic cancer. Growing evidence have consistently shown that obesity,&lt;br/&gt;&lt;br&gt; diabetes, metabolic factors, smoking and alcohol are associated with a high risk of pancreatic cancer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2a9130eb-067a-4804-aae3-2490e9a93a77</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Dorthe_Johansen_avhandling_A4.pdf">https://portal.research.lu.se/files/3337334/1579079.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2685284</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University.

The highest HIV-2 prevalence figures have been reported from Guinea-Bissau. While HIV-1 infection almost invariably leads to progressive immune dysfunction and AIDS, HIV-2 infection is characterised by a smaller proportion of individuals with disease progression to AIDS. &lt;br/&gt;&lt;br&gt; In order to monitor the long-term epidemiological trends of HIV-1 and HIV-2, we performed sentinel studies among pregnant women and followed a cohort of police officers. During the period 1987 to 2004, HIV-2 prevalence declined from 8.3% to 1.5% in pregnant women and during 1990 to 2007, HIV-2 prevalence declined from 13.4% to 6.2% among police officers. We examined specifically if the civil war 1998 – 1999 had any impact on the HIV epidemic in Guinea-Bissau and found that HIV-1 prevalence among pregnant women increased sharply to 5.2% after the conflict but then stabilised around 5%. Among the police officers the HIV-1 prevalence pattern was the same. Also HIV-1 incidence peaked during and shortly after the conflict, but later stabilised at lower levels. Thus we noticed a short-term effect exerted by the war but we did not see any evidence of long-term effects that could be explained by the conflict. &lt;br/&gt;&lt;br&gt; We examined the natural course of HIV-2 infection in seroincident individuals after 20 years of follow-up in the police cohort. As expected, median survival time and disease progression time to AIDS was longer and the CD4+ T cell decline rate was lower compared with HIV-1 infection. There was no significant difference compared with HIV-2 seroprevalent individuals, indicating that earlier studies of HIV-2 seroprevalent individuals were quite representative for HIV-2 infection in general. According to our data, a majority of HIV-2-infected individuals, if followed over longer time, will probably progress to immunodeficiency and clinical disease. Early loss of CD4+ T cells correlated to outcome, just as in HIV-1 infection. We also investigated the difference in disease course in seroincident HIV-1 infection and the influence of contemporaneous HIV-2 infection. The median time of progression to AIDS was 53% longer in dual HIV-1 and HIV-2 infection than in HIV-1 single infection and the difference was more pronounced in the individuals with a recorded HIV-2 infection preceding seroconversion to HIV-1. The epidemiological results correlated to higher CD4+ T cell counts and lower genetic HIV-1 diversity among the dually infected individuals compared with the HIV-1 single-infected. Finally, we investigated the prevalence of other STIs in women with urogenital problems and found high prevalence of several STIs. The most prevalent were Trichomonas vaginalis (20.4%) and Chlamydia trachomatis (12.6%). Infections with Herpes Simplex Virus type 2 and Mycoplasma genitalium were associated with HIV positivity.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Humant immunbristvirus (HIV) orsakar förvärvat immunbristtillstånd (AIDS). HIV/AIDS-epidemin har hittills innefattat över 60 miljoner människor som har infekterats och över 30 miljoner av dessa har avlidit i AIDS. HIV-infektion smittar via blod, sexuellt och från mor till barn vid graviditet eller via bröstmjölk. Vid infektion infogas virusets arvsmassa i den infekterade personens, vilket gör infektionen kronisk. De främsta målcellerna för HIV är en typ av vita blodkroppar, T-hjälpar-cellerna (CD4+-celler). Genom ett gradvis nedbrytande av dessa försvagas den infekterades motståndskraft mot andra sjukdomar och tumörer. HIV föreligger i två varianter – HIV-1 som är globalt förekommande och HIV-2 som huvudsakligen finns i Västafrika och i länder med historiska band dit, framförallt Portugal och Frankrike. Guinea-Bissau har haft de högsta nivåerna av HIV-2-infektion i världen, men förekomsten har varit i sjunkande medan HIV-1-infektion har ökat. HIV-1 leder vanligtvis till AIDS och död inom 10 års tid medan HIV-2 är mindre aggressivt och man har tidigare ansett att endast ca 25-30% leder till AIDS. HIV-2 smittar också i mindre utsträckning än HIV-1. Det har tidigare spekulerats i om HIV-2-infektion kan skydda mot HIV-1-infektion eller fördröja sjukdomsutveckling vid samtidig infektion. Vi har undersökt olika grupper i Guinea-Bissau – gravida kvinnor som sedan 1987 anonymt har provtagits i samband med förlossning, kvinnor som har sökt hälsovård på grund av underlivsbesvär samt en stor grupp poliser. Därmed har vi kunnat följa trender av HIV-1 och HIV-2-förekomst i Guinea-Bissau och hos poliserna även kunnat följa hur många som efter hand har blivit nysmittade av HIV och hur många som har insjuknat i AIDS och avlidit. &lt;br/&gt;&lt;br&gt; Resultaten av våra studier visar att HIV-2-förekomsten stadigt har sjunkit sedan 80-talet och att HIV-1 under senare hälften av 90-talet passerade HIV-2 som den vanligast förekommande typen, resultat som även har påvisats i andra studiepopulationer i landet. Vi såg att det inbördeskrig som förelåg i Guinea-Bissaau 1998-1999 bidrog till en kraftig ökning av HIV-1-förekomst, både hos gravida kvinnor och poliser och bland poliserna kunde vi även konstatera att antalet nyinfekterade ökade markant under och strax efter kriget. Den kraftiga ökningen av HIV-1-infektion var dock inte varaktig utan efter kriget lade sig förekomsten på en jämnt högre nivå i båda grupperna. &lt;br/&gt;&lt;br&gt; De flesta undersökningar av HIV-2 har utgått från individer som redan har varit HIV-2-positiva redan vid studiens begynnelse, där man inte har känt till hur länge personerna har varit smittade. I gruppen av poliser kunde vi genom upprepade undersökningar av alla deltagare fastställa ungefärliga datum för infektionerna och sedan undersöka sjukdomsförloppet hos HIV-2 jämfört med HIV-1. Vi såg då att en något större andel av HIV-2-infekterade individer utvecklade klinisk AIDS (ca 50%) än vad man tidigare trott. Det tog dock nästan dubbelt så lång tid, i medeltal 15 år jämfört med 8,9 år hos HIV-1-positiva individer. Vi såg också en klar koppling mellan tidig förlust av T-hjälparceller och sjukdomsutveckling vilket visar att skeenden tidigt i infektionsförloppet är av betydelse för fortsatt prognos, precis som vid HIV-1-infektion.&lt;br/&gt;&lt;br&gt; Hos individer med HIV-1 och HIV-2 dubbelinfektion såg vi att samtidig HIV-2-infektion verkar skydda mot sjukdomsutveckling av HIV-1, men vi kunde endast klarlägga det i de fall HIV-2-infektion hade förelegat före HIV-1-infektionen inträffade. De kliniska resultaten stämde överens med molekylära studier där vi såg tecken till att nybildning av HIV-1 hämmades i närvaro av HIV-2. Ytterligare insikter i orsakerna till HIV-2:s dämpande inverkan på HIV-1-infektion är viktig för att kunna dra slutsatser som kan användas för framtagande av terapeutiska vacciner som skulle kunna förhindra sjukdomsutveckling hos HIV-1 positiva personer. &lt;br/&gt;&lt;br&gt; Vi undersökte förekomst av andra sexuellt överförbara infektioner förutom HIV. Vi såg höga nivåer av bland annat Trikomonas, herpes- och klamydia-infektion, men låga nivåer av bland annat gonorré och syfilis. HIV-positivitet var kopplad till herpes och Mycoplasma genitalium-infektion. &lt;br/&gt;&lt;br&gt; Inför framtiden är det viktigt att fortsätta övervaka trenderna i epidemierna av HIV-1 och HIV-2, framförallt för att snabbt upptäcka om HIV-1-spridning ökar. Det är av betydelse att sätta upp bättre övervakning av sexuellt överförbara infektioner för att kunna behandla dem korrekt och därmed även förhindra HIV-spridning. Våra resultat visar att även om HIV-2 utvecklar sjukdom i mindre utsträckning än HIV-1 så är det i större utsträckning än tidigare känt och vår förhoppning är att vaksamheten för sjukdom och insättning av antiretroviral terapi kommer att ökas för den här gruppen. I framtiden skulle det vara av värde att få till stånd rutinmässig virusmätning av HIV-2 så att behandling av HIV-2 infektion lättare skulle kunna utvärderas, framförallt då HIV-2-infektion regelmässigt svarar långsammare på antiretroviral behandling än HIV-1. Den största utmaningen avseende HIV-epidemin i Guinea-Bissau är att sätta in tillräckligt stor andel patienter på antiretroviral behandling och att hälsovårdssystemet ska klara av att erbjuda den ökande mängden personer fortsatt behandling.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4a5e0ad3-c1f0-4f30-b3be-a6b2df6369b6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Fredrik_MAY_nsson.pdf">https://portal.research.lu.se/files/3337737/3167948.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1710722</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>HIV-1 HIV-2 Sexually Transmitted Infections Conflict Guinea-Bissau West Africa</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-82-6</identifier> <identifier type="oldLupId">3167642</identifier> <part> <detail type="volume"> <number>2012:20</number> </detail> <extent unit="pages"> <total>236</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-03-09T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>4a5e0ad3-c1f0-4f30-b3be-a6b2df6369b6</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:22:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:22:58+02:00</recordDateApproved> </recordInfo> </mods>

Furthermore to elucidate women’s experiences and views of leisure time physical activity during pregnancy in a qualitative study. Methods: Data sources were: the Aarhus Birth Cohort (1989-1991), the Smoke-free Newborn Study (1996-1998), and the Danish Dystocia Study (2004-2005) including from 2750 to 5750 pregnant women in each study population. Questionnaires provided information about leisure time physical activity (sedentary, light, moderate-to-heavy and competitive sports) and sports. Findings: Pregnant women engaged in moderate-to-heavy leisure time physical activity during pregnancy had a 66% significantly reduced risk of preterm delivery (adjusted OR=0.34, 95% CI:0.14-0.85), while women with light leisure time physical activity had an unchanged risk compared to sedentary women. Practicing more than 1 type of sports was associated with a 91% significantly reduced risk of preterm delivery. Women performing sports 1-2 hours, or 3 hours or more weekly during pregnancy delivered infants with similar birth weight, and had similar risk of infants with low (&amp;lt;2500g) or high birth weight (&amp;gt;4500g) as sedentary women. Similar findings were found when leisure time physical activity was studied. Women engaged in leisure time physical activities prior to pregnancy had the same risk of pre-eclampsia as sedentary women. From prior to pregnancy to the third trimester women’s level of leisure time physical activity decreased. Women with the highest level of leisure time physical activity before pregnancy remained the most physically active in leisure time during pregnancy. The qualitative study indicated that pregnant women desired to continue to be physically active in leisure time. Pregnancy-related discomforts/complications, a growing body and senses of insecurity with physically activity during pregnancy were barriers to maintain previous levels of physical activity. The women experienced that it was most often possible to overcome these barriers and continue to be active, and felt enjoyment and physical well-being from doing this.&lt;br/&gt;&lt;br&gt; Conclusions: This thesis contributes new knowledge on the subject by demonstrating that pregnant women performing leisure time physical activity with the highest intensity had the lowest risk of preterm delivery. No associations between leisure time physical activity and offspring birth weight or risk of pre-eclampsia were found. It is a new dimension that pregnant women described their experiences in overcoming barriers in order to continue to be psychically active.&lt;br/&gt;&lt;br&gt; The overall conclusion is that, that performing sports or higher level of leisure time physical activity prior to pregnancy or during pregnancy is not associated with disadvantages; rather there are some psychological and physical benefits for the mother and her offspring.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/06dec4d0-02ae-4d92-964d-2b340716abc6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="trykket170908.doc">https://portal.research.lu.se/files/3338128/1484220.doc</url> </location> <physicalDescription> <internetMediaType>application/x-ole-storage</internetMediaType> </physicalDescription> <note type="fileSize">892928</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>birth weight</topic> <topic>Pregnancy</topic> <topic>pre-eclampsia</topic> <topic>leisure time physical activity</topic> <topic>preterm delivery</topic> </subject> <subject authority="lup"> <topic>Nursing</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-82-0</identifier> <identifier type="oldLupId">1484183</identifier> <part> <detail type="volume"> <number>2009:94</number> </detail> <extent unit="pages"> <total>160</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-10-23T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Women with GDM have a substantial risk of developing type 2 diabetes later in life, but the risk of developing type 1 diabetes is also increased. GDM increases the risk for macrosomia and caesarean delivery. However, long term prognosis and eventual future risks for children born to mothers with a previous GDM are less well studied. In this thesis women who had GDM during 1995-2010 and their children were investigated.&lt;br/&gt;&lt;br&gt; Aims Paper I-III: Determine how many women with GDM that have beta-cell specific autoantibodies such as glutamic acid decarboxylase antibodies (GADA), tyrosine phosphatase antibodies (IA-2A) and zink transporter 8 antibodies (ZnT8A) during pregnancy, and follow these women after delivery to estimate the risk for later development of type 1 diabetes. Evaluate C-peptide levels in women with GDM as a predictor for future development of diabetes.&lt;br/&gt;&lt;br&gt; Aims Paper IV: Investigate the effects of maternal GDM on childhood body mass index (BMI) compared to the age-specific reference values in Sweden and to their siblings born after a non-GDM pregnancy.&lt;br/&gt;&lt;br&gt; Results Paper I-III: Up to 8% of women with GDM had GADA or IA-2A during pregnancy, and 50% of these women developed type 1 diabetes later in life. GADA was the most frequent autoantibody. When adding ZnT8A as an autoimmune marker in GDM, the number of autoantibody positive women increased by 2%. C-peptide analyses did not add any valuable information for development of either type 1 or type 2 diabetes.&lt;br/&gt;&lt;br&gt; Results Paper IV: BMI for boys was higher at ages 7-10 and for girls at birth and ages 4-12 compared to Swedish reference values. The same BMI pattern was found in siblings born after a non-GDM pregnancy.&lt;br/&gt;&lt;br&gt; Conclusions Paper I-III: Since 50% of women with autoantibodies during GDM develop type 1 diabetes later in life, at least GADA analyses should be performed in all women with GDM by routine.&lt;br/&gt;&lt;br&gt; Conclusions Paper IV: Children to women with a prior GDM have a high risk for overweight and obesity. This is thought to be due to life style habits in the family rather than prenatal factors, even if genetic factors could not be tested in this study, since similar BMI pattern was found in siblings. Early life style intervention is therefore very important in these families.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Graviditetsdiabetes är diabetes som uppkommer eller först upptäcks under en graviditet. Mellan 1-14 % av alla gravida kvinnor runt om i världen drabbas av graviditetsdiabetes och i Sverige är det ungefär 2 %. I Sverige behandlas graviditetsdiabetes med kostråd och om detta inte räcker lägger man till insulinbehandling. Kända riskfaktorer för att utveckla graviditetsdiabetes är övervikt och fetma, som är växande problem runt om i världen. Fetma och övervikt åtföljs även av en rad hälsoproblem, som ökad risk för hjärt- och kärlsjukdomar. Graviditetsdiabetes ökar även risken för att föda stora barn, kejsarsnitt samt förlossningsskador. Det finns dock inte så många studier som är gjorda på långtidsprognos samt eventuella framtida risker för barn vars mammor haft graviditetsdiabetes.&lt;br/&gt;&lt;br&gt; Kvinnor som haft graviditetsdiabetes löper även ökad risk att utveckla diabetes efter sin graviditet. Det vanligaste är att utveckla typ 2 diabetes, som kan bero på att förmågan att producera insulin är nedsatt och/eller att känsligheten för insulin i muskel- och fettceller är nedsatt. I första hand behandlas typ 2 diabetes med kostråd, motion, viktnedgång samt tabletter men ibland behövs även tillägg av insulinbehandling. &lt;br/&gt;&lt;br&gt; Det finns även kvinnor som haft graviditetsdiabetes och som utvecklar typ 1 diabetes istället. Typ 1 diabetes är en autoimmun sjukdom, vilket innebär att man tror att kroppens eget immunsystem har rubbats så att det angriper och förstör de insulinproducerande cellerna i bukspottkörteln. Det beror på att det bildas s.k. antikroppar mot dessa celler vilket gör att immunförsvaret attackerar de insulinproducerande cellerna. Man kan mäta nivåerna av dessa antikroppar med blodprover, och det finns flera olika sorters antikroppar vid typ 1 diabetes. Man vet fortfarande inte vad som sätter igång denna process som leder till att kroppen inte längre kan tillverka sitt eget insulin. Bristen på insulin leder i sin tur till att sockret stannar kvar i blodet och blodsockernivån stiger. Typ 1 diabetes behandlas alltid med insulin. För att mäta hur mycket egen insulinproduktion man har kvar i kroppen används C-peptid, som är en biprodukt från insulin.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studiedesign&lt;br/&gt;&lt;br&gt; Alla kvinnor i Lunds sjukvårdsdistrikt genomgår en 2-timmars glukosbelastning under vecka 28 av sin graviditet som screening för graviditetsdiabetes. De som har haft graviditetsdiabetes tidigare eller har ärftlighet för diabetes genomgår glukosbelastningen redan under vecka 12 av sin graviditet. Kvinnorna kommer fastande till sin mödravårdscentral och får dricka en lösning med 75 gram glukos och efter två timmar mäts deras blodsocker i fingret. Ett blodsocker på ≥10,0 mmol/l räknas som graviditetsdiabetes. De kvinnor som haft graviditetsdiabetes mellan åren 1995-2010 samt deras barn är studerade i denna avhandling.&lt;br/&gt;&lt;br&gt; Metod&lt;br/&gt;&lt;br&gt; Denna avhandling består av fyra delarbeten:&lt;br/&gt;&lt;br&gt; I Arbete I-III undersöktes kvinnor som haft graviditetsdiabetes mellan 1995-2010. Syftet var att se hur många av dessa kvinnor som haft antikroppar mot de insulinproducerande cellerna i bukspottskörteln under sin graviditet. De antikroppar som undersöktes i dessa studier heter GADA, IA-2A samt ZnT8A. Därefter följdes dessa kvinnor för att se hur många som faktiskt utvecklade typ 1 diabetes efter sin graviditet. Betydelsen av C-peptid nivån hos kvinnor med graviditetsdiabetes för att senare utveckla diabetes undersöktes också. &lt;br/&gt;&lt;br&gt; I Arbete IV undersöktes barnen till kvinnor som haft graviditetsdiabetes mellan 1995-2000. Deras längd- och viktkurvor samlades in från BVC och skolor. Syftet var att jämföra deras body mass index (BMI=kg/m2) med Sveriges referensvärden för pojkar och flickor i samma åldrar samt mot BMI hos deras syskon, födda efter en normal graviditet. Åldrarna som studerades var från födseln upp till 12 års ålder. &lt;br/&gt;&lt;br&gt; Resultat&lt;br/&gt;&lt;br&gt; I Arbete I-III var det mellan 5-8 % av alla kvinnor med graviditetsdiabetes som hade antikropparna GADA och IA-2A under sin graviditet. Av dessa kvinnor som haft antikroppar under sin graviditetsdiabetes utvecklade 50 % typ 1 diabetes senare i livet. Dessutom var det många som hade förhöjda blodsockervärden efter sin graviditet, och en del som även hade graviditetsdiabetes vid nästa graviditet. När även förekomst av antikroppen ZnT8A undersöktes, var ytterligare 2 % av kvinnorna med graviditetsdiabetes positiva för denna antikropp. Den vanligast förekommande antikroppen var dock GADA. C-peptid nivåerna hos kvinnorna med graviditetsdiabetes hade ingen betydelse för utveckling av vare sig typ 1 eller typ 2 diabetes efter graviditeten.&lt;br/&gt;&lt;br&gt; I Arbete IV var BMI hos pojkar vars mamma haft graviditetsdiabetes högre vid ålder 7-10 år jämfört med Sveriges referensvärden. För flickor var BMI högre vid födseln samt ålder 4-12 år jämfört med Sveriges referensvärden. Samma BMI mönster fanns hos deras syskon födda efter en normal graviditet.&lt;br/&gt;&lt;br&gt; Slutsats&lt;br/&gt;&lt;br&gt; Arbete I-III: Kvinnor som haft graviditetsdiabetes löper en ökad risk att utveckla typ 1 diabetes (minst 50 %) om de haft antikroppar under sin graviditet. GADA analyser bör göras på alla kvinnor med graviditetsdiabetes, och det är därför viktigt att följa kvinnor som haft antikroppar för att tidigt upptäcka typ 1 diabetes.&lt;br/&gt;&lt;br&gt; Arbete IV: Barn till kvinnor som haft graviditetsdiabetes löper en ökad risk att utveckla övervikt och fetma. Detta tros i första hand bero på livsstilsfaktorer, eftersom deras syskon födda efter en normal graviditet hade samma BMI mönster. Därför är det viktigt att följa dessa familjer och tidigt ge livsstilsråd avseende kost och fysisk aktivitet, för att förhindra uppkomst av övervikt och fetma.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/0cd305e2-7add-47e9-94a0-8a516e19bd1d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa130402.pdf">https://portal.research.lu.se/files/3338155/3633407.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1126111</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="artikel1avhandling.pdf">https://portal.research.lu.se/files/3338157/3633408.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">64430</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="artikel2avhandling.pdf">https://portal.research.lu.se/files/3338159/3633409.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">118176</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="artikel3avhandling.pdf">https://portal.research.lu.se/files/3338161/3633410.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">487774</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Medicine (Lund)</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Gestational Diabetes Mellitus</topic> <topic>autoantibody</topic> <topic>GADA</topic> <topic>ZnT8A</topic> <topic>C-peptide</topic> <topic>overweight</topic> <topic>offspring</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-12-3</identifier> <identifier type="oldLupId">3633404</identifier> <part> <detail type="volume"> <number>2013:42</number> </detail> <extent unit="pages"> <total>120</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-05-03T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>0cd305e2-7add-47e9-94a0-8a516e19bd1d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:03+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:03+02:00</recordDateApproved> </recordInfo> </mods>

The work was done as a part of the resource manager component of the adaptive resource management framework implemented in the European ACTORS project. The framework dynamically allocates CPU resources for the applications. The key element of the framework is the resource manager that combines feedforward and feedback algorithms together with reservation techniques. The reservation techniques are supported by a new Linux scheduler through hard constant bandwidth server reservations. &lt;br/&gt;&lt;br/&gt;The resource requirements of the applications are provided through service level tables. Dynamic bandwidth allocation is performed by the resource manager which adapts applications to changes in resource availability, and adapts the resource allocation to changes in application requirements. The dynamic bandwidth allocation allows to obtain real application models through the tuning and update of the initial service level tables</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/359ec70b-4084-4730-967f-568fa562525b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="romero11lic.pdf">https://portal.research.lu.se/files/3338713/2155051.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2271491</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Research Reports TFRT-3252</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">2155045</identifier> <part> <extent unit="pages"> <total>120</total> </extent> </part> </relatedItem> <note type="additionalInfo">key=romero11lic</note> <recordInfo> <recordIdentifier>359ec70b-4084-4730-967f-568fa562525b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:09+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-23T12:29:27Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:09+02:00</recordDateApproved> </recordInfo> </mods>

The subjects were recruited through a regional screening programme in which oral glucose tolerance tests (OGTTs) are routinely offered to all pregnant women. The prevalence of MODY mutations among women with GDM and a family history of diabetes was found to be 5%. Arabian women were more insulin resistant than Scandinavian women with the same BMI, and showed impaired beta cell compensation for their degree of insulin resistance. GDM might share some genetic features with type 1 diabetes in Scandinavian women. The prevalence of manifest diabetes 5 years after GDM was 30% in our population. Antenatal levels of fasting glucose and HbA1c were identified as biochemical predictors of diabetes following GDM. These are easy to measure, and are relatively cheap, and could help identify women at particularly high risk of developing diabetes postpartum. Counselling regarding future risk of diabetes could then be initiated during pregnancy in high-risk individuals. The rs8050136 variant in the FTO (fat mass and obesity associated) gene was associated with an increased risk of developing postpartum diabetes, probably due to its effect on increasing obesity . Thus, genetic testing may provide a means of identifying pregnant women at high risk of developing postpartum diabetes.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; POPULÄRVETENSKAPLIG SAMMANFATTNING PÅ SVENSKA&lt;br/&gt;&lt;br&gt; Graviditetsdiabetes (GDM) definieras som ett diabetestillstånd som upptäcks under graviditet. Ofta orsakas detta tillstånd av de hormonförändringar som uppträder under graviditet vilka medför en ökad insulinresistens, dvs. ett ökat motstånd mot insulinets effekter. Diagnosen GDM utesluter dock inte diabetes av annan orsak som upptäcks under graviditet. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Efter förlossning försvinner oftast GDM eftersom hormonförändringarna då går tillbaka. Det är dock ett välkänt faktum att GDM innebär en kraftigt ökad risk för kvinnan att senare i livet drabbas av typ 2 diabetes, s.k. vuxendiabetes. Denna risk uppgick i vår studie till 30% inom 5 år. GDM medför också risker för barnet. Obehandlad GDM eller annan diabetes med högt blodsocker hos modern, ger i sin tur högt blodsocker hos fostret. Detta medför en ökad insulininsöndring hos fostret vilket ger risk för alltför kraftig fostertillväxt och förlossningskomplikationer. Det är också visat att GDM för barnets del medför risk för försämrad utveckling under uppväxten.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; GDM och typ 2 diabetes har ofta likartade uppkomstmekanismer, dvs. insulinresistens och bristande insulinproduktion. Släktskapet mellan GDM och typ 2 diabetes är därför tydligt. Maturity Onset Diabetes of the Young (MODY) betecknar andra diabetestillstånd som är monogent nedärvda, har stark ärftlighet och ofta debut före 25 års ålder. I vår studie påvisades MODY-mutationer hos 5% av GDM kvinnor med diabetes i släkten. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Arabiska kvinnor med GDM befanns i vår studie ha en högre grad av insulinresistens och en lägre grad av kompensatorisk ökning av insulinproduktionen jämfört med skandinaviska kvinnor med GDM, vilka å andra sidan uppvisade vissa drag som är gemensamma med typ 1 diabetes, s.k. ungdomsdiabetes.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Eftersom GDM medför risk för framtida diabetes, särskilt typ 2 diabetes, hos drabbade kvinnor vore det önskvärt att finna markörer för framtida diabetesutveckling för att kunna ge individuella råd angående grad av risk och rekommendationer om livsstil. Vår studie visade att högt fasteblodglukos under graviditet, komplicerad av GDM, är förenat med ökad risk för framtida diabetes, vilket andra grupper tidigare också har visat. Vad som däremot var ett nytt fynd i vår studie var att HbA1c, glykosylerat hemoglobin, som används som ett mått på långtidsblodsockret, kan användas på likartat vis. Både fasteblodglukos och HbA1c är lättillgängliga och relativt billiga test, som således skulle kunna tjäna som markörer för framtida utveckling av manifest diabetes efter GDM.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; FTO-genen har tidigare visats ha samband med typ 2 diabetes. Vår avslutande studie påvisade en association mellan varianter i FTO-genen och utveckling av diabetes efter GDM, sannolikt beroende på FTO-genens effekt att ge ökad övervikt. Genetisk testning kan alltså komma att bli ett sätt att identifiera kvinnor med särskilt hög risk att utveckla diabetes efter GDM.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c40f3683-e3dc-4300-ae80-289e3ba4d26e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_till_spikning_100416.pdf">https://portal.research.lu.se/files/3339310/1586055.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">548058</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Oral glucose tolerance tests</topic> <topic>Genetics</topic> <topic>Autoimmunity</topic> <topic>Insulin sensitivity</topic> <topic>Gestational diabetes mellitus</topic> <topic>Insulin secretion</topic> <topic>HbA1c</topic> <topic>Fasting glucose</topic> <topic>FTO-gene</topic> <topic>Postpartum diabetes</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-72-6</identifier> <identifier type="oldLupId">1586047</identifier> <part> <detail type="volume"> <number>2010:57</number> </detail> <extent unit="pages"> <total>125</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-05-20T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>c40f3683-e3dc-4300-ae80-289e3ba4d26e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:12+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:12+02:00</recordDateApproved> </recordInfo> </mods>

Disturbance in the regulation of ME pressure is believed to contribute to the development of chronic ear diseases. In this work subjects with chronic central perforation (CCP), healthy ears with ventilation tubes (VTs), attic cholesteatoma (AC) and Meniere’s disease (MD) were investigated by measuring the ME pressure directly, continuously and long-term, in combination with ET provocation tests. Pathological conditions were characterised by a negative ME pressure during the daytime measurements, indicating an abnormality in the diffusion of gas from the ME and insufficient ET equalizations. &lt;br/&gt;&lt;br&gt; The MEs of subjects with CCP and healthy ears with VTs were open to the atmosphere before the investigations, which influenced the results, resulting in negative ME pressure during the daytime. These results support the theory that the opening per se, impaired or contributed to the impairment in the ME pressure regulation. Subjects with AC showed negative ME pressure and/or episodes of sniff-induced rapid negative pressure changes during the continuous pressure measurements. These findings indicate a clear relation between the disease and impaired ME pressure regulation. Subjects with MD showed an increased incidence of reduced opening capacity of the ET in provocation tests. This indicates that ME of patients with MD are exposed to pressure situations in daily life exceeding the equilibration capacity of the ET, leading to a possible influence of pressure on the inner ear.&lt;br/&gt;&lt;br&gt; The results of these physiological studies have enhanced our understanding of the regulation of ME pressure in diseased ears. Future studies may elucidate the possibility to complement clinical investigations in chronic ear diseases with the method of continuous, long-term measurement of ME pressure.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Mellanörats funktion är att överföra och förstärka ljudvågor från luften i hörselgången till innerörats vätska. Denna överföring är optimal när trumhinnan är i neutral position, dvs när trycket i mellanörat och omgivningen är lika. Avvikelser i mellanörats tryck ses vid kroniska mellanöresjukdomar, fr a är det visat ett samband mellan negativt tryck och sjukdomstillstånd som sekretorisk otit (vätska i mellanörat), retraktioner (indragningar av trumhinnan) och cholesteatom (benröta i örat). &lt;br/&gt;&lt;br&gt; Mellanörats tryck regleras av gasdiffusion över mellanöreslemhinnan i kombination med intermittenta öppningar av örontrumpeten. Gasdiffusionen styrs av de tryckgradienter som uppstår när gaskoncentrationerna mellanörats hålrum och blodet skiljer sig åt. De gaser som är kända för att påverka det totala trycket är koldioxid, syrgas och kvävgas. Diffusionhastigheten mellan dessa skiljer sig åt, då koldioxid har förmågan att uppnå jämvikt inom några minuter, syrgas inom några timmar och kvävgas troligen inte på flera dygn. Örontrumpeten är i det friska örat stängd men öppnar sig bl a i samband med sväljningar och gäspningar. &lt;br/&gt;&lt;br&gt; Forskningsintresse för mellanörats tryckreglering i friska såväl som sjuka öron har funnits i många år. De metoder som har använts har kunnat mäta mellanöretrycket och örontrumpetens öppningsförmåga endast med momentana registreringar i laboratoriemiljö. Vår forskargrupp har utvecklat en metod för kontinuerlig mätning av mellanöretrycket i kombination med provokationstester av örontrumpeten. Med metoden mäts mellanöretrycket direkt via ett hål i trumhinnan. Ett hörselgångsskydd placeras med total täthet i hörselgången. Detta förbinds med mätutrustningen, som bärs i en sele på bröstet. Mätningarna börjar med provokationstesterna och därefter startas den kontinuerliga mätningen, som pågår upp till ett dygn under daglig normal aktivitet och sömn i hemmiljö. Personer med friska öron har tidigare undersökts med vår metod. De visade ett likartat mönster med ett medeltryck under dagtid strax under atmosfärstrycket och med ökning till positivet under sömn. Denna tryckökning beror på att lungventilationen sjunker under sömn och koldioxidhalten i blodet ökar, vilket medför en nettodiffusion av koldioxid in till mellanörat. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De 4 undersökningar som ingår i denna avhandling är gjorda med syfte att öka förståelsen för de fysiologiska mekanismer som styr tryckregleringen i sjuka öron. Undersökningarna gjordes på patienter med kroniska trumhinneperforationer, atticus cholesteatom och Meniere’s sjukdom samt på personer med friska öron som fått insatt ventilationsrör genom trumhinnan.&lt;br/&gt;&lt;br&gt; Mellanöron med kr perforationer är öppna mot omgivningen och har ett mellanöretryck som motsvarar atmosfärstrycket. Våra mätningar gjordes för att bedöma förmågan till tryckreglering. När mätningarna började och mellanöronen stängdes av mot omgivningen av hörselproppen uppstod ett uttalat negativt medeltryck, som kvarstod under tiden patienterna var uppegående. Resultaten visade också en nedsatt förmåga till att utjämna pålagt positivt och negativt tryck med sväljningar i provokationstesterna. Det negativa trycket kunde delvis förklaras av att en gasdiffusion med syrgas från mellanörat började när mätningarna inleddes. Syrgashalten i det öppna mellanörat är ca 15% högre än i ett mellanöra med intakt trumhinna. &lt;br/&gt;&lt;br&gt; För att klargöra påverkan av den högre syrgashalten på våra resultat gjordes en undersökning på friska öron med ventilationsrör, vilka applicerades 1 vecka före undersökningen. Gaskoncentrationerna i mellanöronen kunde då förutsättas ha anpassat sig till luftens, med 15% högre syrgashalt. Resultaten visade att 10/18 fick ett negativt tryck och 8/18 hade ett tryck som var lätt negativt eller runt 0. De personer som hade ett negativt tryck hade alla utom en nedsatt förmåga att svälja undan pålagt tryck, fr a negativt, vid provokationstester. Vår slutsats blev att öppningen mot omgivningen i sig, med kr perforation eller ventilationsrör, gav försämring av mellanöronens förmåga att reglera sitt tryck. &lt;br/&gt;&lt;br&gt; Patienter med atticus cholesteatom har benröta som utgår från en indragningsficka i trumhinnans översta del. Då resten av mellanörat och trumhinnan är opåverkade, har det diskuterats om mellanörats tryck och tryckreglering är en delorsak i utvecklingen av denna sjukdom. Undersökningarna visade ett uttalat negativt medeltryck och reducerad förmåga till tryckutjämningar i provokationstester. Tryckmönstret varierar mellan patienterna. 1/11 hade ett tryck som fluktuerade runt 0, 4/11 hade ett jämnt negativt tryck utan snabba fluktuationer, 6/11 hade perioder med upprepade snabba negativa tryckfall, sniffningar. De senare bedömdes ha sk habituellt sniffbeteende. Majoriteten (6/11) av patienterna hade sniffbeteende, men endast 2/11 kunde i provokationtesterna skapa tryckfall vid sniffningar. Vår slutsats blev att avvikande tryck och störd tryckreglering är med sannolikhet förenat med atticus cholesteatom, samt att den kontinuerliga mätningen är överlägsen provokationstester för att avslöja sniffbeteende. &lt;br/&gt;&lt;br&gt; Patienter med Meniere’s sjukdom lider av återkommande anfall av yrsel, hörselnedsättning och tinnitus. Sjukdomen har sitt ursprung i innerörat men undersökningar har visat att avvikelser i mellanörats tryck möjligen kan påverka symtomen, troligen via trycköverföring till innerörat. Resultaten visade att 15/21 patienter inte kunde utjämna pålagt positivt och negativt tryck med sväljningar och att 9/21 inte kunde skapa tryckökning med Valsalva’s manöver. Alla personer i de tidigare mätningarna på friska öron kunde utföra dessa tester effektivt. Trots detta visade de kontinuerliga mätningarna ett likartat mönster i de två grupperna. Vår slutsats blev att det är troligt att patienter med Meniere’s sjukdom i sin dagliga miljö, när de utsätts för tryckökningar och tryckfall i mellanöronen, inte har förmåga att tryckutjämna via örontrumpeten på ett adekvat sätt. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Slutsatsen är att metoden för kontinuerlig, direkt mellanöretryckmätning är väl användbar för att fysiologiskt beskriva mellanörons tryck och örontrumpetens funktion i sjuka öron. Undersökningarna har gett en ökad förståelse för tryckregleringen i de studerade mellanöronen. Ytterligare studier behövs för att klarlägga öronsjukdomars uppkomst/orsaker och metodens möjlighet till användning som komplement till de kliniska undersökningar som görs idag.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/77b65272-4f58-4422-9728-74ec67845903</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Brattmo_Kappa_G5_1_.pdf">https://portal.research.lu.se/files/3339522/1579036.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1003491</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Otorhinolaryngology, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Chronic otitis media</topic> <topic>Sniffing behaviour</topic> <topic>Tubal opening</topic> <topic>gas diffusion</topic> <topic>Meniere&apos;s disease</topic> <topic>Attic cholesteatoma</topic> <topic>Chronic central perforation</topic> <topic>Tympanic membrane</topic> <topic>Continuous measurement</topic> <topic>Middle ear pressure</topic> <topic>Eustachian tube</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-50-4</identifier> <identifier type="oldLupId">1579035</identifier> <part> <detail type="volume"> <number>2010:35</number> </detail> <extent unit="pages"> <total>52</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&amp;db=PubMed&amp;dopt=Citation&amp;list_uids=12875577</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&amp;db=PubMed&amp;dopt=Citation&amp;list_uids=16012030</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-04-15T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>77b65272-4f58-4422-9728-74ec67845903</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:14+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:14+02:00</recordDateApproved> </recordInfo> </mods>

For instance, in the pancreas, the insulin-producing β-cells are damaged in diabetes patients, and a successful replacement of those cells could provide a cure. These cells can be replaced by organ donation, but owing to a profound scarcity of organ donors, there is a high demand in alternative sources of β-cells. By recapitulating the in vivo developmental pathway, extensively studied in various animal models, it has been demonstrated that hESC can be directed towards a β-cell fate. A complex network of signaling molecules derived from various tissues play multiple roles in the induction events that take place when directing fully pluripotent cells into their different cell fates in vivo, fates that can be followed by analyzing gene and protein expression profiles. The derivation into functional definitive endoderm (DE), the germ layer giving rise to lungs, intestines, liver and pancreas, is a prerequisite for further development towards a pancreatic fate. This thesis covers directed differentiation of hESC by specific factors as well as individual analysis of these. In the first study, hESC are sequentially differentiated first by Activin A (AA)-induction towards DE, and then by treatment with fibroblast growth factor 4 (FGF4) and retinoic acid (RA) to induce differentiation towards foregut endoderm. Importantly, FGF4 does not act as a posterior morphogen as can be observed in vivo, but rather plays an important role in cell survival. However, in combination with RA, which is known to induce dorsal pancreatic fates in vivo, a high level of PDX1+ posterior foregut endodermal cells, characterized by coexpression with SOX9, HNF6, and FOXA2, is obtained. In another study, we demonstrate a novel role of FGF2 as a broad patterning agent in hESC-differentiation. Low levels promote a hepatic fate, intermediate levels promote a pancreatic fate, whereas high levels promote lung and small intestinal fates. Importantly, with this protocol, a fraction of the PDX1+ cells were also positive for NKX6.1, indicating a putative pancreatic progenitor fate. HESC differentiation is most often followed by analyzing gene and protein expression, whereas functional assays to fully understand the in vivo potential of the derived cell types are rare. Here, we present the establishment of a functional in vivo assay in chick embryos for putative DE. The putative DE is derived by directed differentiation from mouse and human ESCs. Putative mouse and human DE is inserted in early chick embryos and integration into the chick endoderm is assayed 48 h later. Specifically, this thesis summarize the outcome of two important differentiation protocols that have provided knowledge on the individual roles of FGF4, RA and FGF2 in directing hESC towards a pancreatic fate, and provide a basis for further optimization towards obtaining pancreatic progenitors, endocrine progenitors, and ultimately fully functional β-cells for future cell replacement therapy.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5b9310c7-46f0-4b0f-a3fe-0b71d3214fbe</url> </location> </relatedItem> <originInfo> <publisher>Stem Cell and Pancreas Developmental Biology, LU</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-51-6</identifier> <identifier type="oldLupId">1384374</identifier> <part> <detail type="volume"> <number>2009:63</number> </detail> <extent unit="pages"> <total>135</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-14T09:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The importance of protein-coding genes in tumorigenesis is well established. Recently, microRNAs (miRNAs) have emerge as key regulator of development and cellular processes such as differentiation, cell growth and cell death; processes closely linked to cancer. The aim of this thesis was to study the impact of miRNAs in prostate cancer. &lt;br/&gt;&lt;br&gt; We show that the expression of miR-34c is downregulated in prostate cancer and inversely associated to shortened overall survival, aggressiveness of the tumor, WHO grade, and occurrence of metastases. The potential of miR-34c being a tumor suppressor in prostate cancer was investigated in vitro. Ectopic expression of miR-34c decreased cell growth, due to an effect on proliferation and apoptosis. Further, ectopic expression of miR-34c suppressed migration and invasion. In a screen of miRNAs regulating the androgen receptor, miR-34c was identified, and shown to inversely correlate to androgen receptor immunostaining in prostate cancer patients. Identification of additional miR-34c targets was performed and one of the identified targets was MET, a receptor tyrosine kinase that is crucial for metastasis. These results suggest that miR-34c has potential as a therapeutic tool in prostate cancer, since it has tumor suppressive functions and target important oncogenes.&lt;br/&gt;&lt;br&gt; The prognostic properties of miR-205 were investigated and it was shown that the expression of miR-205 was inversely associated to shortened overall survival and occurrence of metastasis. In situ hybridization was performed, demonstrating high miR-205 expression in the basal cells of benign prostate tissue glands. Ectopic expression of miR-205 decreased the level of androgen receptor in prostate cancer cells. By a luciferase reporter assay we show that miR-205 directly targets the androgen receptor. This is corroborated in a prostate cancer cohort were miR-205 is found to be significantly lower in castration resistant prostate cancer patients than in hormone naïve patients. Furthermore, miR-205 expression levels are inversely correlated to androgen receptor immunostaining, suggesting that endogenous miR-205 affect the androgen receptor in vivo. &lt;br/&gt;&lt;br&gt; Our findings suggest that miR-34c and miR-205 have potential as diagnostic markers, since their expression is associated with important clinical parameters such as the aggressiveness of the disease and metastasis.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Förr trodde man att de delar av genomet som inte uttrycks till proteiner är oviktiga, eftersom man trodde att det nästan uteslutande är proteinerna som utför de nödvändiga funktionerna i cellen. Man kände till att DNA och RNA innehåller information om hur proteiner ska se ut och när de ska uttryckas, men man kände bara till ett fåtal andra uppgifter som RNA har i cellen. I och med att tekniken har utvecklats har man kunnat sekvensera det mänskliga genomet. En följd av detta var att man insåg att stora delar av genomet transkriberas till RNA utan att translateras till proteiner. Man upptäckte att det finns ett flertal grupper av RNA-strukturer, som har olika uppgifter i cellen. En av dessa grupper är mikro-RNA (miRNA) som kännetecknas av sin ringa längd (ca 20 nukleotider). miRNA kontrollerar genuttrycket genom att binda till budbärar-RNA (mRNA) och förhindra att dessa i sin tur uttrycks till proteiner. Man har idag upptäckt över 2000 olika miRNA i människan. Varje miRNA har ett flertal mRNA som den reglerar och ett mRNA kan vara reglerat av flera miRNA. miRNA har visat sig vara viktiga för att reglera olika processer i cellen såsom celltillväxt, celldöd och metabolism. Det har sedermera visat sig att mängden av olika sorters miRNA skiljer sig mellan frisk vävnad och vävnad med cancer. Man fann vidare att vissa miRNA kunde ha effekter på cellen som främjar eller motar canceruppkomst. I denna avhandling har vi visat att två miRNA, nämligen miR-34c och miR-205, uttrycks lägre i prostatacancer jämfört med frisk vävnad. Vi har kunnat se att dessa miRNA är associerade med kliniska parametrar såsom överlevnad och metastaser. Vidare har vi funnit att miR-34c har tumörhämmande egenskaper genom sin påverkan på celltillväxt, celldöd, migration och invasion.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/28317e5b-dfed-4a31-b9b7-06e72a85f9ee</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappa_120926.doc">https://portal.research.lu.se/files/3340416/3127737.doc</url> </location> <physicalDescription> <internetMediaType>application/msword</internetMediaType> </physicalDescription> <note type="fileSize">772608</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>microRNA</topic> <topic>prostate cancer</topic> <topic>androgen receptor</topic> <topic>MET</topic> <topic>HGF</topic> <topic>miR-34c</topic> <topic>miR-205</topic> <topic>AGO2-RIP-Chip</topic> <topic>noncoding RNA</topic> </subject> <subject authority="lup"> <topic>Medicinal Chemistry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-47-0</identifier> <identifier type="oldLupId">3127698</identifier> <part> <detail type="volume"> <number>2012:84</number> </detail> <extent unit="pages"> <total>150</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-10-31T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>28317e5b-dfed-4a31-b9b7-06e72a85f9ee</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:24+02:00</recordDateApproved> </recordInfo> </mods>

They can tolerate many diverse extreme environments, such as the human body. Even though many of us might associate the word microorganism with infections and disease, most are actually either harmless or even beneficial for us. Those commensals often fight off more dangerous bacteria and might also directly benefit their host. The human skin harbors several different microorganisms, with Propionibacterium acnes being one of the most common bacteria. This Gram-positive anaerobe has long been attributed as the cause of acne vulgaris, and is known to cause severe inflammations on orthopedic implants. However, like most bacteria, P. acnes can be infected by specific bacterial viruses, eg. bacteriophages. If those can contribute to the progress of the diseases mentioned is unknown.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis we have investigated the role of P. acnes as both a pathogen and a commensal, and characterized the phages infecting P. acnes. To undertake those studies, we first had to develop a genetic toolbox to better be able to characterize the bacteria and their phages, since there is a huge lack of molecular tools for the study of P. acnes (Paper I). Furthermore, we found that P. acnes that caused inflammations on orthopedic implants had a higher capacity to form biofilms, than did strains isolated from the skin. Thus, the ability to form biofilm seems to be a characteristic of invasive isolates (Paper II). Even though unwanted on orthopedic implants, we found that colonization by P. acnes on the human skin is beneficial for its host. This is due to that P. acnes secretes a heme-oxygenase that protects our cells against free radicals, and increase the viability of the skin cells (Paper III). Furthermore, we characterized several bacteriophages that could infect P. acnes. Those phages had a high capacity to infect and lyse P. acnes (Paper IV). Finally, the sequencing of two of the phages revealed that the phages were not able to integrate their DNA into its host chromosome, but instead, most likely had a pseudolysogenic relation with their host (Paper V).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In summary, this thesis can conclude that P. acnes is commonly infected by phages, living in a pseudolysogenic relation. Furthermore, colonization by P. acnes might prove both beneficial and harmful for the host, all depending on the site of colonization.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Mikroorganismer finns överallt! De klarar av att överleva i extrema miljöer, extrema pH, extrema temperaturer och kan motstå strålning och gift i doser som vi inte skulle överleva. Framförallt klarar mikroorganismer av att överleva i en specifik extrem miljö - människan. Hundratals olika mikroorganismer bor på och i oss, i ett antal som långt överskrider vårt eget cellantal.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Mikroorganismer är ett samlingsnamn för flera olika typer av små (’mikro’) organismer, som bakterier och virus. Många av oss associerar nog dessa med infektioner och olika sjukdomar, vilket också ett fåtal orsakar. Men tvärtemot vad man kan tro är de flesta bakterier ofarliga, och till och med gynnsamma, genom att de hjälper oss att ta upp näring i tarmarna och skyddar oss mot farligare bakterier. Dessa bakterier tillhör vår normalflora och har en stor del i vårt välbefinnande.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vår hud har flera olika bakterier. Några av de vanligare bakterierna är Propionibakterier, Stafylokocker och Streptokocker. Många av oss kan ha dessa på vår hud utan att de ger några symptom, då de tillhör normalfloran. Men, då tillfälle ges kan även dessa bakterier orsaka opportunistiska infektioner. Detta sker framförallt om vårt försvar mot dem på något sätt är påverkat, genom exempelvis sår (skador eller kirurgiska ingrepp) eller vid nedsatt immunförsvar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En av de hudbakterier som oftast är inblandad i opportunistiska infektioner är Propionibacterium acnes. Bakterien kallades ursprungligen&lt;br/&gt;&lt;br&gt; för Bacillus acnes eftersom den var stavformad (Bacillus-lik) och isolerades från acne. Fastän bakterien isolerades från acne för mer än 100 år sedan råder det fortfarande tveksamheter kring om P. acnes verkligen är orsaken bakom utvecklandet av sjukdomen. Anledningarna till detta är många. Först och främst är vi alla koloniserade av P. acnes utan att utveckla några sjukdomar. Därför hävdar många att en isolering av P. acnes från huden enbart är en kontaminering av provet. Vidare är P. acnes svår att arbeta med av två anledningar. Dels växer P. acnes långsamt och behöver leva i en miljö utan syre. Dels finns väldigt få metoder utvecklade för att studera denna bakterie.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Intresset för denna bakterie har på de senaste åren ökat drastiskt. Fortfarande är intresset stort för den potentiella rollen av P. acnes i utvecklingen av acne. Men senare forskning har även pekat på att P. acnes har en stor roll vid ledimplantatsinflammationer, där ett byte av implantat ofta är nödvändigt för att bli av med infektionen då dessa bakterier ofta är väldigt resistenta mot antibiotika. Detta beror på att bakterien kan bilda ett tjockt lager av socker kring sig (biofilm), som ett pansar som skyddar P. acnes mot antibiotikan. Där kan bakterierna ligga i flera månader till år utan att orsaka någon skada, för att sedan skapa en inflammation. Vidare tyder forskning på att P. acnes kan vara delaktig i utvecklingen av prostatacancer.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Trots ett ökat intresse för att studera denna opportunistiska bakterie, var möjligheten till detta begränsad, då det saknades flera nödvändiga verktyg för detta. Därför utvecklade vi flera verktyg för att på ett enkelt sätt kunna studera hur delar av bakterien kunde medverka till att utveckla sjukdom (Paper I). Dessa verktyg består av två plasmider, som är cirkulärt DNA. Dessa plasmider är konstruerade till att fungera som fabriker i P. acnes och producera olika protein som önskas studeras. Då studier av proteiner i bakterier är en av de grundläggande sätten för att utvärdera hur en bakterie orsakar sjukdom, kommer dessa verktyg att underlätta studier av P. acnes i framtiden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Då P. acnes var så vanligt förekommande vid inflammationer kring ledimplantat, isolerade vi flera av dessa stammar och undersökte vad som skiljde dem från de P. acnes som vi hade på huden. Vi fann då att de P. acnes som hade förmåga att orsaka protesinflammationer alla kunde bilda mer biofilm än de bakterier som isolerades från huden (Paper II). I övrigt hittades inga skillnader mellan de två grupperna av bakterier, och vi kunde fastslå att den troligtvis viktigaste faktorn för att P. acnes orsakade protesinflammationer berodde på dess förmåga att bilda biofilm.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Bortsett från att vara förmögen att orsaka sjukdom bär de flesta av oss på P. acnes utan att bli sjuka. Därför är en rimlig tanke att dessa bakterier också kan vara nyttiga för oss, men på vilket sätt de potentiellt skulle kunna skydda oss har inte utretts. Vi valde att studera ett protein som P. acnes producerar i stora mängder. Detta protein är ovanligt, för det liknar inget hittills undersökt protein i andra bakterier. Därför slogs vi av tanken att detta protein potentiellt kunde vara av stor betydelse för bakteriens interaktion med oss (Paper III). Det visade sig att detta protein, vidare kallat RoxP, kunde skydda våra hudceller mot reaktiva syreradikaler som bildas bland annat av UV-ljus. Hudceller som behandlades med RoxP mådde mycket bättre än celler som inte hade fått RoxP. Detta indikerar att för en frisk person är kolonisering av P. acnes viktigt, då detta bidrar till att skydda vår hud. Därför är det viktigt att inte behandla ospecifikt (eg antibiotika) mot P. acnes om inte denna är upphovet till infektionen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Men P. acnes är inte ensam på spelplanen. Motståndarlaget har en minst lika bred trupp av spelare, och är svurna fiender till P. acnes. Mötena dem sinsemellan brukar alltid resultera i vinst åt något av hållen, men kan även ge ett lika-resultat. Det handlar om bakteriofager. Virus som är ofarliga för oss, men som är dedikerade till att eliminera bakterier. Dessa bakteriofager har två principiellt olika spelarstilar. En av dem är anfallaren, som bara vill komma åt bakterien och förstöra för den. Lyckligtvis för bakterien känner den till ett och annat knep för att skydda sig mot dessa tacklingar.&lt;br/&gt;&lt;br&gt; Den andra spelartypen är mer utav en försvarsspelare. Han gillar att komma nära motståndaren och interagera med dem, även tillfälligt hjälpa dem, för att få motståndaren att känna sig ohotad. Sedan, då tillfälle ges, slår försvarsspelaren till med full kraft. Däremot kan bakterierna även klara sig ur dessa situationer genom olika försvar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Då bakteriofager är kända för att kunna hjälpa bakterierna tillfälligt, var vi intresserade av att undersöka ifall P. acnes som kunde orsaka ledprotesinflammationer också i större utsträckning hade hjälp av bakteriofager (Paper IV). Vi fann att P. acnes i väldigt stor utsträckning hade bakteriofager (70%), men att där inte var någon skillnad mellan sjukdomsframkallande P. acnes och normalflora. Med andra ord, det verkade inte som om bakteriofagerna samspelade med P. acnes i sjukdomsprocessen. Vad vi däremot fann var att bägge lagen hade olika kvaliteter på sina spelare. En del bakteriofager kunde spela anfallare mot nästan alla bakterier med framgång, medan vissa fager enbart kunde dribbla bort ett fåtal motståndare. På samma sätt var kvaliteten i bakterielaget varierande. Medan vissa kunde försvara sig mot nästan alla fagernas anfallare, förutom deras stjärnspelare, borde många av de andra snarare sitta på utbytarbänken då de blev bortdribblade i varje anfall.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Även om det inte verkade som om bakteriofagerna kunde hjälpa P. acnes, bestämde vi oss för att granska detta mer, genom att undersöka två av fagerna närmare. Detta bestod i att vi plockade fram deras DNA, och läste av det, för att se om de hade någon förmåga att hjälpa bakterierna (Paper V). Genom detta fann vi att dessa bakteriofager inte verkar kunna samspela med bakterierna. Däremot kom vi fram till att dessa bakteriofager hade en märklig ”spelstil”, då de inte var strikta anfallare, men inte heller strikta försvarare. Inte enbart var deras spelstil annorlunda, dessutom var deras DNA olikt DNA från andra bakteriofager.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har jag i denna avhandling utvecklat verktyg för att bättre och lättare kunna studera P. acnes. Denna bakterie har både positiva och negativa egenskaper. Positiva genom att den hjälper vår hud att må bra, men negativa då den genom att bilda biofilmer medverkar till inflammation av proteser. Men P. acnes är inte ensam på spelplanen, utan har motståndare i form av bakteriella virus, så kallade bakteriofager. Dessa bakteriofager är vanliga hos P. acnes, men verkar inte bidra till att göra bakterien farligare.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/99189746-39af-4a5a-baea-8682b3851424</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Rolf_thesis_online_version_.pdf">https://portal.research.lu.se/files/3340443/2155133.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1460235</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Propionibacterium acnes</topic> <topic>biofilm</topic> <topic>bacteriophage</topic> <topic>Siphovirus</topic> <topic>pseudolysogeny</topic> <topic>heme oxygenase</topic> <topic>free radicals</topic> <topic>recombinant protein expression</topic> <topic>vector</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-43-7</identifier> <identifier type="oldLupId">2155119</identifier> <part> <detail type="volume"> <number>2011:94</number> </detail> <extent unit="pages"> <total>171</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-10-07T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>99189746-39af-4a5a-baea-8682b3851424</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:25+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:25+02:00</recordDateApproved> </recordInfo> </mods>

A further aim was to describe the context of neonatal care by investigating trends in outcome during a ten-year period in the southern region of Sweden. In total twenty-one fathers were interviewed at three different time points,three to five days, Paper I (n=8), one to three months, Paper II (n=13) and approximately three years,&lt;br/&gt;&lt;br&gt; Paper III (n=8), after their infant was born prematurely. Two different qualitative methods were used,content analysis (Paper I) and hermeneutic phenomenology (Papers II–III).The results of the interviews showed that at the time of the infant’s birth the fathers’ personal needs were of less importance than the needs of their partner and child (Papers I–II). The concept of control and non-control was relevant for the experiences described by the fathers. They seemed to have difficulty remaining in control when they experienced high level of concern, stress and helplessness. When these feelings coincided with low level of security, support and happiness it seemed to end on a level of non-control. In contrast, when security, support and happiness dominated the fathers’&lt;br/&gt;&lt;br&gt; experiences they were able to recapture control (Paper I). The fathers’ lived experience of caring for their very preterm infant (Paper II) was described as a process moving from initial feelings of distance towards feelings of proximity. It was a process that was easily disturbed, and unexpected events out of the father’s control affected and postponed their transition towards proximity. Such events were e.g.deterioration in their partner’s and/or infant’s condition or a transfer of their infant to another unit. A starting point for the father’s transition towards proximity and thereby increasing possibilities to care for their infant was the mother’s well-being. However, being an active participant in their infant’s care was essential (Papers I–II). Fathers’ lived experience of the three years since their very preterm child was born (Paper III) was described as a process of reorganization in life starting on the day the child was discharged from the hospital. The fathers described a journey from past to present time. Being in past time was associated with restrictions in life. The first time at home with the child was described&lt;br/&gt;&lt;br&gt; as hard and they had difficulties handling the situation of living as a family with a preterm child. They experienced tensions within the relationship and had to face their own inadequacy. As time went by the fathers started to experience empowerment. This was on one hand associated with their ability to mature in their parental role and on the other hand with their ability to adjust to the situation around them. Being in present time was associated with building a secure base. The fathers described how&lt;br/&gt;&lt;br&gt; they had lived through the experience of having a preterm-born child and had adapted to living an ordinary family life. They were now able to believe in a future for the family as a whole. Paper IV had an epidemiological design. During the ten-year period (1995-2004) the proportion of very preterm infants remained stable, around 1.2% of al births, but there was a significant annual increase in the rate of preterm infants born before 25 gestational weeks. The decrease in mortality was&lt;br/&gt;&lt;br&gt; significant only for births &amp;lt;25 gestational weeks. For the whole group, very preterm infants, a significant increase in BPD and sepsis was found.&lt;br/&gt;&lt;br&gt; It was demonstrated that the rate of infants born before 25 gestational week increased during the 10-year period. This implies that the number of parents who commencing parenthood to the most vulnerable infants will increase over time. Neonatal care has traditionally examined the experiences of mothers of preterm-born children while studies focus exclusively on fathers have been sparse even though increasing. The findings from the qualitative studies reveal that fathers undergo a fragile&lt;br/&gt;&lt;br&gt; process not only in connection with their child’s preterm birth but also during the years to come. An increased understanding of their experiences may serve as a basis for adjusting neonatal nursing care during the infant’s hospitalization and after the infant’s discharge.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8c99ec00-0423-436e-b963-9f2ae58f6b64</url> </location> </relatedItem> <originInfo> <publisher>Pia Lundqvist, Dept of Health Sciences, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Preterm infant</topic> <topic>mother</topic> <topic>father</topic> <topic>parents</topic> <topic>experience</topic> <topic>NICU</topic> <topic>trend</topic> <topic>morbidity</topic> <topic>mortality</topic> </subject> <subject authority="lup"> <topic>Nursing</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-70-5</identifier> <identifier type="oldLupId">1270557</identifier> <part> <detail type="volume"> <number>2008:117</number> </detail> <extent unit="pages"> <total>56</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-12-11T13:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

This may lead to myocardial infarction, increased morbidity, mortality, and health care costs. &lt;br/&gt;&lt;br&gt; In the first study, myocardial metabolism was investigated before, during, and after 30 min of regional coronary artery occlusion, utilizing the microdialysis technique, concomitantly with the monitoring of global circulation and local coronary artery flow in an open chest pig model. Myocardial interstitial metabolites demonstrated characteristic, significant, and reproducible changes as decreased glucose, increased glycerol, and increased lactate/pyruvate ratio during ischemia, normalizing after reperfusion. Of special interest was found that myocardial glycerol concentrations remained high initially at reperfusion, raising the hypothesis of this release corresponding to reperfusion injury. This model was used for the next two studies. &lt;br/&gt;&lt;br&gt; In cardiac surgery, episodes of myocardial ischemia or decreased myocardial performance are highly expected to occur. Patients with poor cardiac function will have a double benefit of an inotropic drug with anti-ischemic properties. Levosimendan may have this potential. In the second study, it was demonstrated that an infusion of levosimendan started before the coronary artery occlusion, as compared to start during the ischemia, reduced the effect of ischemia on the myocardial metabolism, improved, and preserved cardiac performance during this period. &lt;br/&gt;&lt;br&gt; In recent years, concerns with the use of perioperative beta-blockers have been debated. Beta-blockers may inhibit the pharmacological preconditioning elicited by volatile anaesthetics. In the third study, it was demonstrated that levosimendan, in the presence of beta-blockade, was still able to induce a cardioprotective effect on the myocardial ischemic metabolism. &lt;br/&gt;&lt;br&gt; During cold cardioplegic storage, or in the future during preservation of donor hearts by perfusion, monitoring of the donor heart before transplantation may be of benefit. We hypothesized, that myocardial microdialysate glycerol will reflect progressive damage. As the first step in pursuing this, in the fourth study, the course of myocardial metabolites was investigated during ten hours of cold cardioplegic storage. An accelerating myocardial glycerol accumulation was demonstrated during storage, after an initial stable period, probably reflecting the acceptable storage time.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e0b72107-1c8e-4dd5-8b7e-756ead46b60f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Metzsch_2009-109_ONLINE_PDF.pdf">https://portal.research.lu.se/files/3341066/1502513.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">544268</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Anaesthesiology and Intensive Care, Lund</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>heart preservation</topic> <topic>metoprolol</topic> <topic>levosimendan</topic> <topic>beta-blockers</topic> <topic>pharmacological preconditioning</topic> <topic>myocardial ischemia</topic> <topic>cardioprotection</topic> <topic>glycerol</topic> <topic>microdialysis</topic> <topic>cold cardioplegic storage</topic> </subject> <subject authority="lup"> <topic>Anesthesiology and Intensive Care</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-97-4</identifier> <identifier type="oldLupId">1502506</identifier> <identifier type="doi">10.1111/j.1399-6576.2005.00877.x</identifier> <location> <url>http://dx.doi.org/10.1111/j.1399-6576.2005.00877.x</url> </location> <accessCondition type="restrictionOnAccess">yes</accessCondition> <part> <detail type="volume"> <number>2009:109</number> </detail> <extent unit="pages"> <total>128</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-12-04T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>e0b72107-1c8e-4dd5-8b7e-756ead46b60f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:33+02:00</recordDateApproved> </recordInfo> </mods>

Radical prostatectomy serves as the first line of treatment for patients with localised prostate cancer. However, in many cases the cancer will recur. It is currently difficult to identify those patients at a high risk of tumour recurrence. Therefore, molecular markers associated with and predicting disease recurrence are needed to help identify patients and to better understand the signalling pathways in prostate cancer cells. The protein tyrosine kinase (PTK) receptors and cytosolic signalling proteins as well as the protein tyrosine phosphatases (PTPs) have important roles in the regulation of growth of the benign and malignant prostate gland. Here, we have studied the expression and function of the PTP SHP-1 in prostate cancer cell lines and in clinical material from patients that underwent radical prostatectomy. We have also analysed the expression of SHP-2 in prostate cancer cell lines and human prostate cancer tissue. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We performed several different in vitro and in vivo experiments that were evaluated with methods such as immunohistochemical staining of tissue micro arrays (TMA), polymerase chain reaction (PCR), Western blot, eukaryotic cell transfections, proliferation assays, PTP enzymatic activity assay, caspase assay, flow cytometric assays, cell growth in vivo in nude mice, migration and invasion assays.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Our results show that a low or absent SHP-1 expression might serve as a marker to identify prostate cancer patients at an increased risk of tumour recurrence. We also demonstrate that proliferation and apoptosis can be regulated by modulations of the SHP-1 expression in prostate cancer cells. SHP-1 expression and activity is reduced in the LNCaP cell line that was long-term stimulated with IL-6, showing that the cytokine might regulate SHP-1 activity. SHP-1 is also able to reduce growth of PC3 cells growing in vivo in nude mice. These results suggest that SHP-1 is a negative modulator by inhibiting prostate cancer cell proliferation through the growth factor and cytokine-induced pathways in prostate cancer cells. Our results also suggest that SHP-2 may have similar activity in prostate cancer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6ca27a5a-7f2f-4b0a-978b-44ac8718fe84</url> </location> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Prostate cancer SHP-1SHP-2 IL-6phosphorylationsignalling pathways</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-38-2</identifier> <identifier type="oldLupId">1553617</identifier> <part> <detail type="volume"> <number>2010:24</number> </detail> <extent unit="pages"> <total>127</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-03-26T09:00:00+01:00</dateOther> <note type="additionalInfo">Department affilation moved from v1000588 (Tumour Biology, Malmö) to v1000562 (Department of Translational Medicine) on 2016-01-18 14:39:32.</note> <recordInfo> <recordIdentifier>6ca27a5a-7f2f-4b0a-978b-44ac8718fe84</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:05:11Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:35+02:00</recordDateApproved> </recordInfo> </mods>

Patients are entitled to be informed on an individual and adequate level. &lt;br/&gt;&lt;br&gt; Evidence-based guidelines should, in most cases, be followed also in the treatment of elderly to avoid suboptimal treatment, for example for cardiovascular conditions, or risky prescriptions in the case of renal impairment.&lt;br/&gt;&lt;br&gt; Objectives: 1. To describe frail elderly patients’ knowledge about and attitudes towards their medicines and to explore their experiences of receiving information about their medications. 2. To describe how well general practitioners (GPs) adhere to guidelines when using renal risk drugs in frail elderly patients and when treating elderly with cardio¬¬vascular disease and to evaluate local education of GPs as a tool for improvement.&lt;br/&gt;&lt;br&gt; Methods: (Paper I, IV) For each prescribed medicine, the patient was asked about the indication and possible adverse effects. Attitudes were investigated with the Beliefs about Medicines Questionnaire. Semi-structured interviews covering questions on information about medication were analysed qualitatively. (Paper II) Medications for elderly patients in nursing homes were registered and the use of renal risk drugs was compared to renal function, estimated from s-creatinine and s-cystatin C. (Paper III) Data about GPs adherence to guidelines was collected from the medical records of patients aged ≥ 65 with a cardiovascular diagnosis. Local education was organized, followed by repeated measurements.&lt;br/&gt;&lt;br&gt; Results: The knowledge about indication was satisfying but the knowledge about possible adverse effects was poor. The patients believed strongly in the benefits of their medication. The elderly felt comfortable with information when they trusted their physician or their medication, when they received enough information from the prescriber or when they knew how to find out sufficient information by themselves. They felt insecure if they were anxious, if the availability of medical care was poor or if they did not receive enough information. Reduced renal function was common (53%) in nursing home patients but s-creatinine was often normal. Renal risk drugs were rarely prescribed. The adherence to guidelines about cardiovascular diseases was low among GPs, but educational efforts appeared to increase the adherence.&lt;br/&gt;&lt;br&gt; Conclusions: To receive an adequate drug therapy in the elderly, GPs should pay attention to patients’ need for suitable information on their medication and follow evidence-based guidelines about when to initiate and when to avoid certain drugs.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bakgrund &lt;br/&gt;&lt;br&gt; Med stigande ålder ökar antalet kroniska sjukdomar hos patienten och därmed även mängden läkemedel. I grunden är läkemedel bra produkter som lindrar, botar eller förebygger sjukdomar och lidande. Dock är äldre (&amp;gt;65 år) mer utsatta för potentiellt negativa effekter av läkemedel. Äldre personer använder många läkemedel, i synnerhet gäller det de äldre som bor på särskilda boenden. Ju fler läkemedel en patient intar desto större är risken för negativa bieffekter som interaktioner och biverkningar. Behandlingarna måste därför anpassas och alltid utvärderas. Med ökad ålder sker ett antal förändringar som successivt försämrar funktionen i olika organsystem. Detta innebär att äldre patienter har mindre marginaler och därmed ökad risk för negativa effekter av läkemedel. &lt;br/&gt;&lt;br&gt; Den viktigaste förändringen är äldres minskade njurfunktion. Det är därför nödvändigt att inför läkemedelsförskrivning skatta njurfunktionen för att rätt dosera och kanske utesluta vissa läkemedel, för att undvika biverkningar och/eller ytterligare försämring av njurfunktionen. Det finns många sätt att uppskatta njurfunktion, men ingen är optimal. Vanligt är att mäta ett blodprov – kreatinin. Att enbart bedöma njurfunktion med kreatininvärdet är dock inte tillförlitligt, speciellt inte hos äldre. Bättre är att uppskatta den sanna njurfunktionen med olika formler, baserade på blodprov.&lt;br/&gt;&lt;br&gt; Det finns också risker med underbehandling och vid flera tillstånd har man sett att äldre i lägre omfattning behandlas fullt ut med rekommenderade läkemedel. En högre ålder får inte betyda att en effektiv behandling undanhålls patienten. Tillgängliga vårdprogram som bygger på vetenskapligt beprövade data bör i normalfallet följas även vid behandling av äldre, även om ett individanpassat behandlingssätt är viktigt speciellt vid multisjuklighet. &lt;br/&gt;&lt;br&gt; Det är av största vikt att följsamheten till ordinerad behandling blir så god som möjligt. Vanligaste orsaken till dålig följsamhet (compliance) är glömska, men den kan också bero på missförstånd eller att patienten avsiktligt låter bli att ta sin medicin till exempel på grund av biverkningar eller rädsla för långsiktiga följder av behandlingen. God följsamhet är av vikt för god behandlingseffekt och minskad risk för läkemedelsrelaterade problem. Följsamheten är bl. a. relaterad till kunskap om och attityder till sina läkemedel. Kunskapen påverkas av att informationsöverföringen sker på ett så optimalt sätt som möjligt. Man har tidigare sett att många patienter upplever otillräcklig information från förskrivande läkare och har obesvarade frågor. Många är också rädda för biverkningar, men har fått bristande information om dessa.&lt;br/&gt;&lt;br&gt; Antalet äldre ökar ständigt i vårt samhälle och i vårdapparaten. I befintliga studier avseende läkemedelsbehandling är ofta äldre patienter exkluderade, trots att de står för den största läkemedelsanvändningen. Eftersom äldre drabbas hårdare vid felaktig läkemedelsanvändning, är det av stor vikt med ytterligare forskning för att optimera äldres läkemedelsanvändning, med inriktning både på patientfaktorer och på läkarfaktorer. Detta gäller speciellt i primärvården där den största delen av läkemedels¬förskrivningen sker. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Syftet med avhandlingen var att belysa olika aspekter av kvaliteten i läkemedels-behandling av äldre i primärvården.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Resultat&lt;br/&gt;&lt;br&gt; I studie I mättes kunskap om och attityd till sin medicinering hos sköra äldre patienter i eget boende. Kunskapen om anledningen till behandling var relativt tillfredsställande, men kunskapen om sidoeffekter var svag. Patienter med fem eller fler läkemedel samt patienter med ApoDos (separat förpackade påsar med medicin för varje dos) hade signifikant lägre kunskap. Patienterna hade stark tro på nyttan av sina mediciner. Eftersom kunskapen delvis kan förmodas vara beroende av den information som getts om läkemedlen, följdes denna studie upp av studie IV, som var en intervjustudie som utforskade patienters erfarenheter av information om förskrivna läkemedel. Det framkom att det finns faktorer som gör att patienter känner sig nöjda och trygga, t ex när de har stort förtroende för sin doktor eller litar på sin medicinering och även när de vet själva var och hur de skaffar sig tillräcklig kunskap om sina mediciner. Det finns också faktorer som skapar otrygghet eller rent av missnöje, t ex när det är svårt att nå sin doktor eller när informationen är för sparsam.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie II undersökte njurfunktion och användning av riskläkemedel vid sänkt njurfunktion hos sjukhemspatienter i tre olika kommuner. Minskad njurfunktion sågs hos drygt hälften av patienterna, men normalt kreatininvärde sågs i 41 % av patienterna med minskad njurfunktion. Riskläkemedel förskrevs ganska sällan. Det verkar alltså finnas en god medvetenhet bland allmänläkare om vikten att njurfunktionsanpassa läkemedelsförskrivningen. Läkaren måste vara observant på njurfunktion innan läkemedel förskrivs till en äldre patient och bör inte bara lita på kreatininvärdet. Njurfunktion bör beräknas innan riskläkemedel förskrivs, men olika sätt att uppskatta kan ge skilda resultat.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie III var en journalstudie och ett lokalt kvalitetsförbättringsprojekt som mätte hur väl allmänläkare följer regionala vårdprogram vid behandling av äldre patienter med hjärt-kärlsjukdom. Studien undersökte också om utbildningsprogram kan förbättra följsamheten till rekommendationer. Man kunde se att följsamheten till rekommendationer i många fall var låg, men att den kunde förbättras genom upprepade informationsmöten och feedback till patientansvarig läkare.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/13abee83-7c72-4cb5-ad3c-6389b39501c2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Sara_Modig.pdf">https://portal.research.lu.se/files/3341721/3131757.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2163790</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Generel Practive/Family Medicine, Clinical Sciences in Malmö.</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Elderly</topic> <topic>drug therapy</topic> <topic>medication knowledge</topic> <topic>beliefs about medicines</topic> <topic>adherence</topic> <topic>guidelines</topic> <topic>renal function</topic> <topic>renal risk drugs</topic> <topic>cardiovascular disease</topic> <topic>GP</topic> <topic>primary care</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-24-1</identifier> <identifier type="oldLupId">3131646</identifier> <part> <detail type="volume"> <number>2012:61</number> </detail> <extent unit="pages"> <total>49</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-11-16T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>13abee83-7c72-4cb5-ad3c-6389b39501c2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:43+02:00</recordDateApproved> </recordInfo> </mods>

A poor level of physical-environment qualities and the re-creation of institutional atmospheres in these settings have been found in recent studies. The research focus in the psychiatric field has, however, largely neglected these topics and the available knowledge does not provide sufficient evidence to draw any conclusions in terms of which physical environmental aspects support the well-being of people with SMI. The aim of this thesis is thus to reduce this knowledge gap and identify physical-environment affordances for psychosocially supportive housing facilities. The HEI model and a salutogenic approach are the thesis’ theoretical backgrounds that have led to the identification of physical-environment affordances, which have proven to be crucial for people’s well-being. Such affordances are operationalized in terms of visual pleasantness, homelikeness and indirect environmental effects. SHF (N = 20) were investigated with a multi-place approach by experts (N = 5), user-group panel (N = 3), people with SMI (N = 72) and staff (N = 117) (social actors). Four papers contribute to test the influence of the selected affordances on people with SMI: comparison of the views of different social actors (Paper I), evaluation of their impact on social climate (Paper II), observed behaviors (Paper IV) and on place attachment and quality of life (Paper III). Results suggest that SHFs with perceived greater physical affordances (visual pleasantness and indirect environmental effects) were associated with positive social climate perceptions. Moreover, the indirect environmental effects were found to be supportive for observed behaviors of interactions, attachment to place and quality of life responses. Place attachment and social climate mediated the effects of the physical environment. These findings suggest that future planning of SHF should focus on a housing design that sustains possibilities for social interaction, privacy regulation and restoration (indirect environmental effects) in order to support well-being outcomes among people with SMI. Methodological, theoretical and practical design implications are discussed.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bostäder med särskild service som upplevs ge möjlighet till socialt umgänge, avskildhet och återhämtning har positiva effekter på livskvaliteten hos människor med psykisk funktionsnedsättning. Vidare visar resultaten från denna avhandling att den visuella upplevelsen av miljön och upplevelsen av hemlikhet är betydelsefulla för att etablera en stödjande atmosfär. Boendemiljöer som utformas med hänsyn till dessa kvaliteter bidrar till att skapa en god platsförankring, en positiv social miljö mellan boende och personal och utveckla positiva sociala relationer mellan människor med psykisk funktionsnedsättning. Denna avhandling belyser därmed vilka fysiska faktorer som påverkar människor med psykisk funktionsnedsättning och kan bidra till att vägleda planering och utformning av nya bostäder med särskild service. Tidigare bodde personer med allvarliga psykiska funktionshinder på institutioner ofta lokaliserade till utkanten av befintlig bebyggelse. Tillvaron var uppbyggd kring strikta rutiner, avskildhet och restriktioner vilket hade en negativ inverkan på deras välbefinnande. Sedan 1960-talet har nya boendeformer successivt introducerats i syfte att minska de negativa effekterna av institutionsmiljöerna. Idag är så kallade bostäder med särskild service en av de mest förekommande boendeformerna för människor med psykisk funktionsnedsättning och det är denna boendeform som studeras i avhandlingen. Boendeformen kännetecknas av att ett mindre antal personer med psykisk funktionsnedsättning bor tillsammans och har daglig tillsyn av personal. Forskning har visat att det förekommer undermåliga boendemiljöer även i denna form av boende, vilket i vissa fall medfört att en stämning som påminner om den som fanns i de tidigare institutionsmiljöerna har återskapats. Även om det är allmänt vedertaget att vår omgivning påverkar människors psykiska hälsa, och särskilt sårbara individer, så finns det lite kunskap om vilka fysiska aspekter av bostäder med särskild service som bidrar till välbefinnande och god livskvalitet hos människor med psykisk funktionsnedsättning. Målet med denna avhandling är således att öka förståelsen för vilka aspekter av den fysiska miljö som kan främja en positiv utveckling för dessa människors välbefinnande.&lt;br/&gt;&lt;br&gt; The housing environment of people with severe mental illness&lt;br/&gt;&lt;br&gt; 68&lt;br/&gt;&lt;br&gt; Totalt omfattar arbetet empiriska studier av 20 olika bostäder med särkild service i södra Sverige Vid datainsamlingen har experter från miljöpsykologi och arkitektur, såväl som individer med psykisk funktionsnedsättning samt deras sjukvårdpersonalen medverkat.

The epidemiology of AS in Sweden has not been extensively studied previously.&lt;br/&gt;&lt;br&gt; Radiographic and self-perceived health information from 1,005 men aged 69-81 years, showed a prevalence of moderate to severe radiographic sacroiliitis of 1.4% (95% Confidence Interval (CI): 0.7-2.4), with modest impact on health. Medical records of a representative sample of 500 patients with a registered visit to a physician with a diagnosis of AS or undifferentiated spondyloarthritis (uSpA) in the National Patient Register (NPR) (2007-2009) were reviewed. These diagnoses had high validity, as 70% of patients with an AS diagnosis fulfilled the modified New York (mNY) criteria for AS and 79% of patients with a diagnosis of uSpA fulfilled any set of the SpA criteria. Based on clinically diagnosed patients with AS in the NPR, identification of referents from the general population and linkage of these two groups to other national registers, the prevalence and mortality of AS were studied. The prevalence of clinically diagnosed AS was 0.18% in 2009, with higher estimates in men, in northern Sweden, and in those with lower level of education. Men more often had anterior uveitis and treatment with TNF-inhibitors compared to women, and women had more often peripheral arthritis, psoriasis and treatment with oral glucocorticosteroids. The all-cause mortality was increased in patients with AS compared to the general population, overall (age- and sex-adjusted hazard ratio (HR) 1.60 (95% CI: 1.44-1.77)) and separately for males and females. Predictors of death within the AS cohort included a lower level of formal education, general co-morbidities and joint surgery.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/33503839-1fc0-4461-a07b-77af6acabd8d</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-141-5</identifier> <identifier type="oldLupId">5367859</identifier> <part> <detail type="volume"> <number>2015:62</number> </detail> <extent unit="pages"> <total>122</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-28T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>33503839-1fc0-4461-a07b-77af6acabd8d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:23:54+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:23:54+02:00</recordDateApproved> </recordInfo> </mods>

This research was also undertaken to examine the association between loneliness and healthcare consumption. In addition, the reserach explored the experience of loneliness and&lt;br/&gt;&lt;br&gt; evaluated the effects on loneliness, symptoms of depression and life satisfaction of a case management intervention for frail older people.&lt;br/&gt;&lt;br&gt; Study I was a quantitative study with a longitudinal design involving persons 78 years or older and drawn from the Swedish National Study on Aging and Care. The sample comprised of 828 people at baseline (2001) who were followed-up after three years (n=511, 2004) and six years (n=317, 2007). The sample was divided into two groups, based on if the persons felt lonely or not. Factors such as personality traits, health complaints, self-reported health status and life satisfaction were included for identifying associated factors and predictors for loneliness. Studies II-IV were based on a main study with an experimental design, comprising 153 persons, 65+ years, living at home, with dependency in ADL and repeated contact with the healthcare services. Study II had a cross-sectional design drawn from the baseline assessment&lt;br/&gt;&lt;br&gt; (n=153) of the main study. Self-reported data and register data was used to investigate the association between use of healthcare and loneliness, health status and health complaints. Study III had a qualitative design and explored the experience of loneliness by performing interviews with 12 persons (10 women), recruited from the main experimental study. The interviews were analysed by using qualitative content&lt;br/&gt;&lt;br&gt; analysis. Study IV was a randomised controlled trial, including 153 persons randomised to an intervention (n=80) or control group (n=73) and evaluated the effect of a case management intervention after six and 12 months.Three outcomes were evaluated in regards to effectiveness; loneliness, symptoms of depression and life satisfaction.&lt;br/&gt;&lt;br&gt; The results in Study I showed that 52 per cent of the sample at baseline felt lonely sometimes or often (mean age 84 years). The strongest associated factor for loneliness was living alone (OR=6.1, 95%, CI=3.8-9.9) and the strongest predictors for loneliness at both follow-ups, at three and six years, was feeling lonely at baseline (OR=7.2, CI=3.9-13.4 and OR=5.4, CI=2.8-10.5). Those associated factors and predictors that were identified were mainly related to psychosocial outcomes. Study II showed that 60 per cent of the frail older participants (mean age 82 years) had experienced loneliness occasionally or more often during the previous year. Those who felt lonely used significantly more outpatient services, including visits at the emergency department, compared to their peers who did not feel lonely (p=0.026). Only depressed mood was found to be independently associated with total use of&lt;br/&gt;&lt;br&gt; outpatient services (B=7.4, p&amp;lt;0.001). In Study III, the experience of loneliness among frail older people was interpreted in the overall theme “Being in a Bubble” illustrating as being in an ongoing world but excluded because of the participants’ social surroundings and the impossibility to regain losses. The theme “Barriers” illustrated how participants had to face barriers, physical, psychological and social barriers for&lt;br/&gt;&lt;br&gt; overcoming loneliness. The theme “Hopelessness” revealed the experience when not succeeding in overcoming the barriers and was characterised by loss of spirit and seeing loneliness as an unchangeable state. The last theme “Freedom” illustrated a positive co-existing dimension of loneliness which offered independence and time for reflection and recharging. Study IV evaluated the effect of a case management&lt;br/&gt;&lt;br&gt; intervention for frail older people living at home in regards to loneliness, symptoms of depression and life satisfaction. At baseline, there were no significant differences between the intervention and control groups in regards to the main outcomes or sociodemographic factors. According to intention-to-treat no significant differences were found for any of the outcomes, at any time point between the two groups.&lt;br/&gt;&lt;br&gt; When accounting for complete cases, significant differences in favour of the intervention were found at six months for loneliness (RR=0.5, p=0.028) and life satisfaction (ES=0.4, p=0.028), as well as for depressive symptoms after 12 months (ES=0.5, p=0.035).&lt;br/&gt;&lt;br&gt; Loneliness is fairly common among older people and once the feeling is established, it is likely to stay. Factors related to psychological wellbeing appeared as the major reasons for loneliness. Frail older people tend not to differ in regards to prevalence, compared to older people in general. Frail older people who felt lonely used more outpatient services, including visits to the emergency department compared to their&lt;br/&gt;&lt;br&gt; not lonely peers. However, it was not loneliness per se that was found to be associated with use of healthcare but rather depressed mood. The experience of loneliness among frail older people showed that it was a prevalent issue, regardless of intensity and was associated with physical and social losses. Case management for frail older people was not effective in regards to loneliness, symptoms of depression and life satisfaction. Nevertheless, there were indications that case management could be beneficial in terms of these outcomes. &lt;br/&gt;&lt;br&gt; Loneliness is an important factor that could be associated with lower wellbeing and needs to be actively targeted. Because of the complexity, where single causes are difficult to isolate a comprehensive and individualised approach is recommended. Loneliness can be problematic regardless of intensity and is likely to be unresolved, if left unattended. This implies that appropriate assessments of&lt;br/&gt;&lt;br&gt; loneliness and other aspects of psychological wellbeing should be undertaken.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f80444b7-d40e-4a4e-be0e-cc15c2795450</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Taube_Kappa_150415_version_2.pdf">https://portal.research.lu.se/files/3346619/5363951.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">938104</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-137-8</identifier> <identifier type="oldLupId">5363946</identifier> <part> <detail type="volume"> <number>2015:58</number> </detail> <extent unit="pages"> <total>127</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-22T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f80444b7-d40e-4a4e-be0e-cc15c2795450</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:24:05+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-05-05T05:47:57Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:24:05+02:00</recordDateApproved> </recordInfo> </mods>

Because the DP rat develops T1D spontaneously, it is a prime laboratory animal for dissecting the genetics of T1D susceptibility without the need for external manipulation. The BB rat is comprised of two separate substrains; the diabetes prone (BBDP) and the diabetes resistant (BBDR). Failure to express the Gimap5 protein is associated with lymphopenia (lyp) and linked to T1D in the BBDP rat. In an intercross between F1(BBDP x F344) rats we identified a rat with a recombination event on rat chromosome (RNO) 4, allowing us to fix 34Mb of F344 between D4Rat253 and D4Rhw6 in the congenic DR.lyp rat line with two Mb of BBDP DNA, encompassing the Gimap5 mutation, introgressed on the DR genetic background. The aim of this thesis was to characterize the F344 DNA introgression, test the hypothesis that the introgression would result in 1) no effect on T1D development or 2) protection from T1D, generate congenic sublines and positionally clone and characterize the resulting candidate genes on rat RNO4.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Material and Methods: The F344 fragment in the DRF.f/f rat line was fixed onto the DR.lyp background in a total of nine backcross and seven intercross matings. To generate DRF.f/f congenic sublines, DRF.f/f rats were crossed to inbred BBDR or DR.lyp/lyp rats and the offspring genotyped, phenotyped for lymphopenia and monitored for T1D. Positional candidate genes were then subjected to coding sequence analysis, cDNA sequencing and/or quantitative real-time (qRT) PCR expression analysis.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Results: DRF.f/f rats, homozygous for the F344 allele, were lymphopenic but did not develop T1D while all (100%) DR.lyp/lyp rats developed T1D by 83 days of age. Generation of congenic sublines revealed that reduction of the DRF.f/f F344 DNA fragment by 26 Mb (42.52 Mb-68.51 Mb) retained complete T1D protection. Further dissection revealed that a 2 Mb interval of F344 DNA (67.41-70.17 Mb) (Iddm38) resulted in 47% protection while retaining &amp;lt;1 Mb of F344 DNA at the distal end (Iddm39) resulted in 28% protection, both of which significantly delayed onset. Comparative analysis of T1D frequency in the DRF.f/f congenic sublines refined the Iddm38 and Iddm39 intervals to approximately 670 Kb between SNP SS105325016 and D4Rat26 and 340 Kb proximal to Gimap5, respectively. Coding sequence analysis revealed TCR Vβ 8E, 12 and 13 as candidate genes in Iddm38 and Znf467 and Atp6v0e2 in Iddm39. Quantitative RT-PCR analysis of whole organ as well as in FACS sorted thymocytes and peripheral T-cells stained with CD4 and CD8 monoclonal antibodies showed a reduction in expression of four out of five Gimap genes located within the Iddm39 interval, in addition to Gimap5, in DR.lyp/lyp spleen and mesenteric lymph nodes (MLN) when compared to DR.+/+. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Conclusions:&lt;br/&gt;&lt;br&gt; Our data demonstrates that introgression of a 34 Mb region of the F344 genome, proximal to the mutated Gimap5 gene, renders the congenic DR.lyp/lyp rat T1D resistant despite being lymphopenic. Generation of congenic sublines revealed that spontaneous T1D in the BB rat is controlled, in part, by at least two genetic loci, Iddm38 and Iddm39, in addition to the Gimap5 mutation on RNO4. Coding sequence analysis revealed TCR Vβ 8E, 12 and 13 as candidate genes in Iddm38 and Znf467 and Atp6v0e2 as candidate genes in Iddm39. Quantitative RT-PCR expression analysis suggests that the lack of the Gimap5 protein in the DR.lyp/lyp congenic rat impairs expression of the entire Gimap gene family and regulates T-cell homeostasis in the peripheral lymphoid organs. The molecular identification and characterization of the genetic factors protecting from T1D in the DRF.f/f congenic rat line should prove critical &lt;br/&gt;&lt;br&gt; to disclose the mechanisms by which T1D develops in the BB rat.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/08c1b88c-7e6c-416a-bf3a-69a173b1349d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Fuller.pdf">https://portal.research.lu.se/files/3347636/1510161.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">518935</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Genetics</topic> <topic>Lymphopenia</topic> <topic>BB Rat</topic> <topic>Type 1 Diabetes</topic> <topic>T Cell Receptor</topic> <topic>Autoimmunity</topic> <topic>Gimap</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-03-0</identifier> <identifier type="oldLupId">1497010</identifier> <part> <detail type="volume"> <number>2009:114</number> </detail> <extent unit="pages"> <total>121</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-12-09T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>08c1b88c-7e6c-416a-bf3a-69a173b1349d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:24:15+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:24:15+02:00</recordDateApproved> </recordInfo> </mods>

The operator listened to synthetically produced sound signals from continuous flow. The&lt;br/&gt;&lt;br&gt; human ear was most sensitive to sound frequencies in the lower range from this type of flow.&lt;br/&gt;&lt;br&gt; Study II. Doppler signals were recorded from the umbilical artery of sheep fetuses. An objective&lt;br/&gt;&lt;br&gt; sound measure, MAXpeak-15dB (the frequency band where the energy level had decreased by 15&lt;br/&gt;&lt;br&gt; dB from its maximum level) was identified and found to correlate well with the sonographer’s&lt;br/&gt;&lt;br&gt; subjective grading and with the traditional waveform analysis.&lt;br/&gt;&lt;br&gt; Studies III and IV. Fetoplacental and uteroplacental circulation was investigated before and&lt;br/&gt;&lt;br&gt; after treatment with corticosteroids of women at risk for preterm birth. A transient decrease in&lt;br/&gt;&lt;br&gt; pulsatility index (PI) in the umbilical artery and ductus venosus occurred after steroid treatment.&lt;br/&gt;&lt;br&gt; MAXpeak-15dB increased significantly after corticosteroids parallel with a decrease in PI and was&lt;br/&gt;&lt;br&gt; more sensitive to the changes in flow.&lt;br/&gt;&lt;br&gt; Study V. MAXpeak-15dB was applied on umbilical artery Doppler signals in high-risk pregnancies&lt;br/&gt;&lt;br&gt; and was found to show similar results as the traditional PI in predicting the probability of&lt;br/&gt;&lt;br&gt; composite adverse pregnancy outcome. Receiver operating characteristic curves were used with&lt;br/&gt;&lt;br&gt; an area under curve (AUC) of 0.842 for MAXpeak-15dB and 0.836 for PI. When the two parameters&lt;br/&gt;&lt;br&gt; were combined the predictive performance was improved (AUC 0.894). MAXpeak-15dB might thus&lt;br/&gt;&lt;br&gt; provide additional clinically useful information on the hemodynamics of fetoplacental circulation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9a470501-99ed-417b-bce1-609787363bd9</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Gynaecology, Obstetrics and Reproductive Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-090-6</identifier> <identifier type="oldLupId">4905135</identifier> <part> <detail type="volume"> <number>2015:10</number> </detail> <extent unit="pages"> <total>47</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-01-23T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>9a470501-99ed-417b-bce1-609787363bd9</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:24:18+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:24:18+02:00</recordDateApproved> </recordInfo> </mods>

Lentiviral vectors are particularly attractive since this vector type can transduce both dividing and non-dividing cells, have a relatively large cloning capacity, can sustain long-term transgene expression and have low immunogenicity. The specificity of the vector is however important to avoid potential off-target effects and make the treatment as safe and beneficial as possible. The promoter plays a large part in the specificity of the vector. In this thesis we describe two approaches to find disease-specific promoters that can be used in gene therapy vectors for treatment of Parkinson’s disease. Another way to restrict transgene expression is by post-transcriptional regulation. This can be achieved by introducing miRNA target sites in the transgene cassette. We describe such an approach to restrict transgene expression to resident microglia in the brain. Perturbation in the GABAergic signalling is present in Parkinson’s disease and several other disorders of the CNS. Glutamic acid decarboxylase is the rate-limiting enzyme in the synthesis of GABA and the GABA output of a neuron may be altered when the level of GAD present in the cell is modified. In this thesis we show two different approaches to specifically regulate the expression of the endogenous GAD67 gene. GAD67 is one of the two isoforms of glutamic acid decarboxylase present in the brain. The first approach uses a customised zinc-finger based transcription factor to upregulate GAD67 while the second approach use a synthetic microRNA to downregulate GAD67. Both of these tools could potentially be used in disease modifying treatments of diseases where aberrant GABAergic signalling is present.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Vid genterapi för man in nya gener i en individs celler. Detta kan göras med hjälp av modifierade&lt;br/&gt;&lt;br&gt; virus. Dessa virus kan föra in den nya genen, den såkallade transgenen, in i värdcellen men inte bilda&lt;br/&gt;&lt;br&gt; nya viruspartiklar. I många fall är det viktigt att begränsa i vilka celler som transgenen uttrycks, då det&lt;br/&gt;&lt;br&gt; producerade proteinet kan ge bieffekter i andra celltyper. Det finns flera olika sätt att designa genterapivektorn för att begränsa uttrycket av transgenen till en eller ett urval av celltyper. I den första delen av denna avhandling fokuserar vi på detta.&lt;br/&gt;&lt;br&gt; En promotor styr i vilka celler, när och hur mycket en gen ska uttryckas. Uttrycket av transgenen&lt;br/&gt;&lt;br&gt; kan därför begränsas genom att välja en lämplig promotor i vektorn. Ett specifikt uttryck i nervceller&lt;br/&gt;&lt;br&gt; kan till exempel uppnås genom att titta på vilka protein som uttrycks specifikt i nervceller och sedan&lt;br/&gt;&lt;br&gt; ta promotorn som styr uttrycket av genen för det proteinet och sätta in den i vektorn. I den första&lt;br/&gt;&lt;br&gt; studien i den här avhandlingen beskriver vi en metod som kan användas för att välja promotorer som&lt;br/&gt;&lt;br&gt; är relevanta för Parkinsons sjukdom. Dessa promotorer kan användas för att uttrycka transgenen i ett&lt;br/&gt;&lt;br&gt; urval av celler som påverkas av denna sjukdom. Ett annat sätt att begränsa uttrycket av transgenen&lt;br/&gt;&lt;br&gt; är att lägga till en sekvens som är komplementär till ett miRNA. miRNA är små bitar RNA som inte&lt;br/&gt;&lt;br&gt; kodar för något protein. Dessa finns naturligt i cellen där de binder till komplementära sekvenser på&lt;br/&gt;&lt;br&gt; mRNA (proteinkodande RNA) och gör att mindre av det proteinet som mRNAt kodar för produceras.&lt;br/&gt;&lt;br&gt; I den andra studien i den här avhandlingen har vi använt denna metod för att begränsa uttrycket&lt;br/&gt;&lt;br&gt; av transgenen till mikroglia. Vi har lagt till en sekvens som är komplementär för miRNA9 i vektorn.&lt;br/&gt;&lt;br&gt; Detta leder till ett transgenuttryck i mikroglia, för där uttrycks inte miRNA9, men stänger av uttrycket&lt;br/&gt;&lt;br&gt; in de andra celltyperna i hjärnan då dessa uttrycker miRNA9.&lt;br/&gt;&lt;br&gt; I den andra delen av denna avhandling använder vi genterapi för att specifikt påverka en gen som&lt;br/&gt;&lt;br&gt; finns naturligt i cellens genom. GAD67 är ett enzym som är hastighetsbegränsande i syntesten av&lt;br/&gt;&lt;br&gt; GABA. GABA är den vanligaste inhibitoriska neurotransmittorn i hjärnan och en felaktig GABAsignalering&lt;br/&gt;&lt;br&gt; har upptäckts i ett fleratal sjukdomar. Exempel på sådana sjukdomar är Parkinson’s sjukdom&lt;br/&gt;&lt;br&gt; och Huntingtons sjukdom. Genom att modifiera mängden GAD67 i nervcellen kan kanske&lt;br/&gt;&lt;br&gt; frisättningen av GABA ändras. Detta skulle kunna lindra några av symptomen som uppstår vid dessa&lt;br/&gt;&lt;br&gt; sjukdomar. Transkriptionsfaktorer finns naturligt i cellen där de binder till promotorn hos gener och&lt;br/&gt;&lt;br&gt; reglerar genuttrycket. I den tredje studien i den här avhandlingen använder vi en egendesignad transkriptionsfaktor för att öka uttrycket av GAD67. Det går att utnyttja cellens miRNA-system för att&lt;br/&gt;&lt;br&gt; minska uttrycket av en målgen. Detta kan göras genom att designa syntetiska miRNA. I den fjärde&lt;br/&gt;&lt;br&gt; studien i denna avhandling använder vi ett syntetiskt miRNA för att minska uttrycket av GAD67.&lt;br/&gt;&lt;br&gt; Dessa verktyg skulle kunna användas för att modifiera GAD67-uttrycket i cellkärnor som visar för&lt;br/&gt;&lt;br&gt; liten respektive för stor GABA-frisättning.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b9b5bb44-69ff-4441-ac0d-4eb202e4a3ed</url> </location> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Parkinson’s disease Gene therapy Cell specific GAD67 Rat Striatum Substantia nigra pars reticulata</topic> </subject> <subject authority="lup"> <topic>Basic Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-70-3</identifier> <identifier type="oldLupId">4017603</identifier> <part> <detail type="volume"> <number>2013:98</number> </detail> <extent unit="pages"> <total>116</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-09-27T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>b9b5bb44-69ff-4441-ac0d-4eb202e4a3ed</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:24:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:24:30+02:00</recordDateApproved> </recordInfo> </mods>

To promote energy efficiency, various policy instruments have been in place since the 1970s. Nevertheless, energy efficiency improvements still lag behind their potential in the building sector, which indicates that there is a lack of knowledge about the performance of policies. To further encourage energy efficiency in buildings, there is a need for ‘policy learning’ to gain knowledge and experience about polices and their performance. &lt;br/&gt;&lt;br&gt; This doctoral thesis analyses the role of policy instruments and policy packages in the development of energy efficient end-use building technologies and their emerging markets. Technologies include windows, insulation, heat pumps and passive houses. By using the lenses of innovation theory, the concept of learning, and transaction cost economics, this work analyses the outcome of various policy packages, the development of technologies and markets, and policies influencing such development. The research identifies key policy instruments for technology change.&lt;br/&gt;&lt;br&gt; The results show that technology change requires timely, long-term and flexible policy support. This involves diverse policy packages, rather than single policy instruments, designed to support technology development and their emerging markets. The research also highlights the importance of policy support for learning processes in the innovation system and as a determinant of technology change. Building codes, technology procurement and voluntary standards were found to be essential drivers for introducing energy efficient technologies to the market. Beside regulatory and voluntary building standards, testing facilities and networking activities have been identified as key drivers for technology change. Transaction costs, on the other hand, can significantly hinder energy efficiency improvements. Transaction costs of single technologies implemented in passive house renovations can be 200% higher than the transaction costs of conventional technologies. These costs, however, can be reduced. &lt;br/&gt;&lt;br&gt; New approaches to transaction cost reduction and flexible, long-term, policy packages have resulted in more energy efficient windows, improved insulation, widespread use of high quality ground-source heat pumps and growing demand for the application of passive technologies and the passive house concept. In Sweden, for example, the thermal performance of the best available windows has improved more than two-fold in the past forty years. In the same period, the market share of energy efficient windows increased from 20% to 80%. Another example of successful policy interventions is the emergence of markets for ground-source heat pumps in Sweden and Switzerland. Since the mid-1990s, the efficiency of ground-source heat pumps has improved by 13-36%, annual sales have increased around 20-30% and costs decreased between 50% and 80%, in Sweden and Switzerland, respectively. As the case of a Swedish passive house-oriented renovation shows new approaches to promote learning, e.g. enhanced organizational awareness-raising and new forms of collaboration and information platforms, ultimately result in significant cost reductions at different actors’ stake.&lt;br/&gt;&lt;br&gt; This thesis delivers important inputs to the field of policy learning that can be used to enhance, reshape and improve future policies for the development and diffusion of building-sector energy efficiency technologies. Enhanced policy learning, in turn, will help overcome barriers to energy efficiency to support innovation and facilitate technology change for sustainable energy use.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Over thirty years of experience shows that energy efficiency is the easiest, fastest, and cheapest strategy to reduce today’s rampant energy use. To enhance energy efficiency, governmental intervention and business strategies are needed. The question of which governmental policies are the most effective to support energy efficiency remains unanswered. Policy learning and policy evaluations take us closer to the answer. This doctoral thesis provides valuable insights into which policies supported energy efficiency in the building sector. The results show that mandatory energy performance standards of buildings, so-called building codes, and technology procurements are key policies for introducing energy efficient building technologies to the market. In addition, voluntary approaches, such as the passive house standard, testing activities and enhanced networking are essential business strategies for the diffusion of these technologies.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c4c6f877-fab4-42f3-a367-3589023e6c11</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Bernadett_Kiss_Doctoral_Dissertation.pdf">https://portal.research.lu.se/files/3348617/3738663.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4500033</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>International Institute for Industrial Environmental Economics, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Policy learning</topic> <topic>technology change</topic> <topic>energy efficiency</topic> <topic>building</topic> </subject> <subject authority="lup"> <topic>Other Social Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>IIIEE Dissertations</title> </titleInfo> <identifier type="issn">1402-3016</identifier> <identifier type="isbn">978-91-87357-02-2</identifier> <identifier type="oldLupId">3738662</identifier> <part> <detail type="volume"> <number>2013:1</number> </detail> <extent unit="pages"> <total>180</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popscienceBuilding Energy Efficiency.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3348615/3801963.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-06-14T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>c4c6f877-fab4-42f3-a367-3589023e6c11</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:24:34+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:24:34+02:00</recordDateApproved> </recordInfo> </mods>

Numerous reports have demonstrated that excessive infiltration of neutrophils is a&lt;br/&gt;&lt;br&gt; rate-limiting step in septic lung damage. We observed that targeting neutrophil functions appeared more&lt;br/&gt;&lt;br&gt; relevant than inhibiting platelet activation in severe infections triggered by streptococcal M1 protein. In study&lt;br/&gt;&lt;br&gt; II, it was shown that simvastatin was a powerful inhibitor of neutrophil infiltration in acute lung damage&lt;br/&gt;&lt;br&gt; triggered by streptococcal M1 protein. The inhibitory effect of simvastatin on M1 protein-induced neutrophil&lt;br/&gt;&lt;br&gt; recruitment appeared related to reduced pulmonary generation of CXC chemokines. Following the mevalonate&lt;br/&gt;&lt;br&gt; signaling pathway, checking downstream effectors, both Rho/Rho Kinase and p38 MAPK signaling pathway&lt;br/&gt;&lt;br&gt; played critical roles in M1 protein-induced lung recruitment of neutrophils via formation of CXC chemokines&lt;br/&gt;&lt;br&gt; and Mac-1 expression. In addition, our findings also suggested that farnesyltransferase was a potent regulator&lt;br/&gt;&lt;br&gt; of CXC chemokine formation in alveolar macrophages and that inhibition of farnesyltransferase not only&lt;br/&gt;&lt;br&gt; reduces neutrophil recruitment but also attenuates acute lung injury provoked by streptococcal M1 protein.&lt;br/&gt;&lt;br&gt; Thus, these new data may provide a basis for the development of more specific and effective treatment of&lt;br/&gt;&lt;br&gt; patients with STSS.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/64c8150d-815f-4718-8292-4be0d0085e27</url> </location> </relatedItem> <originInfo> <publisher>Surgery Research Unit, Clinical Science, Malmö</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-67-8</identifier> <identifier type="oldLupId">3164132</identifier> <part> <detail type="volume"> <number>2012:104</number> </detail> <extent unit="pages"> <total>72</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-11-30T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>64c8150d-815f-4718-8292-4be0d0085e27</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:24:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:24:43+02:00</recordDateApproved> </recordInfo> </mods>

One topic is how to handle delayed and out-of-sequence measurements (OOSMs) in tracking systems. The motivation for this is that with technological development and exploitation of more sensors in tracking systems, OOSMs gain more significance in various applications. The thesis derives a Bayesian formulation of the OOSM problem for nonlinear state-space models, when a linear, Gaussian substructure is present. This formulation is utilized when developing two particle-filter algorithms for the OOSM problem. The algorithms improve estimation accuracy and tracking robustness, compared with methods that do not utilize the linear substructure. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A second topic is sensor fusion for improved autonomy in vehicles. A novel approach to model-based joint wheel-slip and motion estimation of four-wheeled vehicles is developed. Unlike other approaches, the method explicitly models the nonlinear slip dynamics in the state and measurement equations. Excellent and consistent accuracy for all relevant states are reported, both during steady-state driving and aggressive maneuvering. The method applies to general classes of four-wheeled vehicles and it only assumes kinematic relationships.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Optimization-based control methods have found their way into automotive applications. &lt;br/&gt;&lt;br&gt; Optimal control for vehicles typically results in control inputs that give aggressive maneuvering. Proper models are therefore crucial. An investigation on what impact different vehicle models and road surfaces have on the optimal trajectories in safety-critical maneuvers is presented. One conclusion is that the control-input behavior is highly sensitive to the choice of chassis and tire models. Another conclusion is that the optimal&lt;br/&gt;&lt;br&gt; driving techniques are different depending on tire-road characteristics.&lt;br/&gt;&lt;br&gt; The conclusions motivate the design of a novel, two-level hierarchical approach to optimal trajectory generation for wheeled vehicles. The first novelty is the use of a nonlinear vehicle model with tire modeling in the optimization problem at the high level. This provides for better coupling with the low-level controller, which uses a nonlinear model predictive controller (MPC) for allocating the torques and steer angles to the wheels. This is combined with a linear MPC, which is used when the nonlinear MPC fails to converge in time.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The thesis also describes a hierarchical design flow for performing online, minimum-time trajectory generation for four-wheeled vehicles with independent steer&lt;br/&gt;&lt;br&gt; and drive actuation, combined with real-time obstacle avoidance. The approach is based on convex optimization. It therefore allows fast&lt;br/&gt;&lt;br&gt; computations, both for trajectory generation and online feedback-based obstacle avoidance. The proposed method is fully implemented on a&lt;br/&gt;&lt;br&gt; pseudo-omnidirectional mobile platform and evaluated in experiments in&lt;br/&gt;&lt;br&gt; a path-tracking scenario.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/44660456-97db-4229-99cb-0670d25e05fe</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="berntorp2014phd_hela.pdf">https://portal.research.lu.se/files/3352295/4407278.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">25877007</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>particle filtering</topic> <topic>optimal control</topic> <topic>automotive systems</topic> <topic>out-of-sequence measurement</topic> <topic>autonomy</topic> <topic>model predictive control</topic> <topic>sensor fusion</topic> <topic>wheel slip</topic> <topic>dynamic optimization</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>PhD Thesis TFRT-1101</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="issn">0280-5316</identifier> <identifier type="isbn">978-91-7473-948-0</identifier> <identifier type="oldLupId">4407277</identifier> <part> <extent unit="pages"> <total>328</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popscienceFörarlösa fordon.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3352293/4407280.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-05-23T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>44660456-97db-4229-99cb-0670d25e05fe</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:24:49+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-18T12:24:54Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:24:49+02:00</recordDateApproved> </recordInfo> </mods>

It poses problems when interpreting both experimental and theoretical studies since we are currently forced to consider only reduced variants of the actual circuitry of the brain. Since there exist problems that do not appear until a system is sufficiently complex, there are no guarantees that the results stemming from such reduced studies can be extrapolated to actually apply to the real brain.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The initial part of the thesis investigates the properties of the spinocerebellar circuitry of the nervous system, and its role in motor control. Especially the cerebellum has been shown to play an important role in the coordination of fast movements, such as reaching and pointing. Paper I uses theoretical reasoning based on previously found experimental studies to show that the cerebellar circuitry should not be studied in isolation if the aim is to explore cerebellar function. The inputs provided by the pre-cerebellar circuits in the spinal cord and brain stem can significantly reduce the complexity of the problem that the cerebellar circuitry needs to solve.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Papers II, IV and V investigate the properties of the mossy fiber pathways. Both the spinal border cell neurons that ascend the ventral spinocerebellar tract with sensorimotor information related to locomotion and the neurons of the cuneate nucleus that process tactile information are studied using behavioral stimulation, either in vivo (Paper V) or through modeling (Paper IV). The results indicate both that the overall activity of the circuitry provides the cerebellum with an easy to interpret encoding, but the individual neurons can at the same time segregate underlying features and details of the stimulus. This result can be seen as a parallel to the found statistics of spike generation in Paper III. Even though the neurons have complex electrodynamic properties, their average activity, described by their firing statistics is surprisingly similar between neurons with vastly different morphology.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Paper VI reviews the theoretical grounds for sparse coding, and compares them to recent experimental findings, both in the cerebellum and the neocortex. While there are beneficial properties of certain sparse codes, the experimental results rather indicate that the circuitry both in the cerebellum and the neocortex do not actively maintain a sparse population code.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1226c2df-7521-485f-98ce-dc05139971ab</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_165x240_v3.pdf">https://portal.research.lu.se/files/3356134/7762500.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">10701443</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Neural basis for sensorimotor control</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>spike firing statistics</topic> <topic>spontaneous activity</topic> <topic>sensorimotor control</topic> <topic>tactile processing</topic> <topic>cuneate nucleus</topic> <topic>sparse coding</topic> <topic>spinal border cells</topic> <topic>cerebellum</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-168-2</identifier> <identifier type="oldLupId">7762498</identifier> <part> <detail type="volume"> <number>2015:89</number> </detail> <extent unit="pages"> <total>167</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-09-07T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>1226c2df-7521-485f-98ce-dc05139971ab</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:25:06+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:25:06+02:00</recordDateApproved> </recordInfo> </mods>

We first show that the intracellular cytoplasmic protein XSufu acts as a dual regulator of Hedgehog (Hh) and Wnt signals during neural induction and patterning in the Xenopus embryo. We further reveal an essential role of XSufu in the crosstalk of the two pathways, in which β-catenin activates Hh signalling upon overexpression of Gli1, and Gli inhibits Wnt signalling upon overexpression of β-catenin. A biphasic model for the role of XSufu in anteroposterior patterning of the neural plate is presented suggesting that XSufu suppresses anterior Gli and posterior β-catenin transcription factors in a dose-dependent manner. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Then we introduce the secreted serine protease xHtrA1 as feedforward stimulator of long-range FGF signalling. Fibroblast growth factor (FGF) signals activate transcription of xHtrA1, and xHtrA1 stimulates FGF4 and FGF8 gene activities, allowing positive feedback regulation. We also show that xHtrA1 triggers proteolytic cleavage of xBiglycan, xSyndecan-4, and xGlypican-4, suggesting a model, in which xHtrA1 through cleaving proteoglycans releases FGF/proteoglycan complexes that act as long-range messages during anteroposterior patterning, mesoderm induction, and neuronal differentiation. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Third, we present Xenopus retinol dehydrogenase-10 (XRDH10) as a critical enzyme for embryonic vitamin A metabolism and retinoic acid (RA) synthesis in the developing embryo. We show that XRDH10, which oxidizes vitamin A to retinal, is transcriptionally inhibited by RA, suggesting negative feedback regulation at the first step of RA biosynthesis. XRDH10 cooperates with XRALDH2, which further oxidizes retinal to bioactive RA, in Spemann’s organizer during dorsoventral patterning of the embryo. We also show that the nested gene expression and cooperate action of XRDH10 and XRALDH2 form a biosynthetic enzyme code that establishes RA gradients along the anteroposterior neuraxis.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; En ordentlig bildning av det centrala nervsystemet är viktigt för ett nyfött barn eller en vuxen. Den senaste tidens kartläggning av människans arvsmassa har lett till identifiering av ungefär 23000 gener, många av dem aktiva i det utvecklande nervsystemet. Men lite är känt om deras funktion och hur de samverkar för att påverka utvecklingen av organ så komplexa som den mänskliga hjärnan. Eftersom många sjukdomar såsom neurodegenerativa sjukdomar och cancer orsakas av defekta gen-aktiviteter, är en bättre förståelse för reglering och funktion av gener under normal utveckling avgörande för att utveckla nya terapeutiska behandlingar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Djurmodellsystem används för att besvara utvecklingsbiologiska frågor, och vårt labb valde den afrikanska grodan Xenopus laevis. Skäl för att använda detta djur är de producera stora mängder ägg, befruktning i en petriskål är genomförbar, och embryon utvecklas snabbt utanför moder-grodan. Xenopus embryon är mycket större än jämförbara skeden i musen, vilket medgör experimentella manipulationer som mikrokirurgi och mikroinjektion. Viktigt är också att 79 % av de gener som är associerade med en sjukdom i människa bevarats i grodan.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det centrala nervsystemet utvecklas från ett fält av enhetligt utformade celler, kallat neural-platta. Molekylära markörer visar att cellerna i neural-platta redan på ett tidigt stadium förvärvar distinkta regionala identiteter längs huvud-svans axeln i embryot. Som ett resultat av denna mönsterprocess utvecklas neural-platta så småningom till framhjärna, mitthjärna, bakhjärna och ryggmärg. Att förstå de signaler som driver formandet av neural-platta är av stor fokus i denna studie.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Denna studie fokuserar på ett begränsat antal utvecklings-signaler, nämligen Hedgehog (Hh), Wnt, Fibroblast tillväxtfaktor (FGF) och retinoinsyrasignaler. Vi analyserar regleringen och integreringen av dessa signaler genom tre distinkta gener i det tidiga Xenopus-embryot.&lt;br/&gt;&lt;br&gt; I den första delen av denna studie, karakteriserar vi en gen, kallad Sufu, och visar att den spelar en viktig roll i regleringen av aktiviteten av Hh och Wnt signaler under bildning och formning av neural-platta. Vi beskriver vidare hur Hh och Wnt signalbanor kommunicera med varandra och identifierar en grundläggande funktion hos Sufu i överhörningen mellan de två signalvägar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi introducerar sedan en gen, kallad xHtrA1 med viktiga funktioner i korrekt bildande av huvud- och svansstrukturer, neural mönster och bildandet av mogna nervceller i embryot. xHtrA1 aktiveras av FGF signaler och i sin tur stimulerar FGF signalering via en mekanism som innebär proteinklyvning och frisättning av aktiva FGF signaler utanför celler.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För det tredje beskriver vi en ny funktion för en gen med akronymen XRDH10 som är involverad i syntesen av retinoinsyra från vitamin A. Vi visar att XRDH10 regleras av retinoinsyra och förser embryot med lämpliga mängder av denna signal under mönstring av det centrala nervsystemet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Genom att ge en bättre förståelse för de molekylära mekanismer som är inblandade i normal tidig neural utveckling hos Xenopus kan dessa resultat leda till ny kunskap för att lösa det intrikata signalnätverket för det centrala nervsystemets utveckling hos människan.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f52e462a-a854-4d37-adc7-e7682e619bfa</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Hooi_Min_Tan.pdf">https://portal.research.lu.se/files/3358141/2157975.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">27104698</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Suppressor-of-fused</topic> <topic>Gli</topic> <topic>β-Catenin</topic> <topic>Neural</topic> <topic>Xenopus</topic> <topic>FGF</topic> <topic>Signalling</topic> <topic>HtrA1</topic> <topic>RDH10</topic> <topic>Retinol dehydrogenase</topic> <topic>Retinoic acid</topic> <topic>Spemann&apos;s organizer</topic> <topic>Induction</topic> <topic>Gradient</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-37-6</identifier> <identifier type="oldLupId">2155147</identifier> <part> <detail type="volume"> <number>2011:88</number> </detail> <extent unit="pages"> <total>142</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-10-14T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>f52e462a-a854-4d37-adc7-e7682e619bfa</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:25:13+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:25:13+02:00</recordDateApproved> </recordInfo> </mods>

The challenge is to determine the main cause and to decide whether the intervention should be medical or surgical. Diagnosis is done by a combination of rhinoscopy, subjective and objective assessments of nasal obstruction. Rhinomanometry measures the nasal airway resistance (NAR) for each nasal cavity. Septal deviations are common with prevalences of up to 58% with the majority having no nasal complaints. Septoplasty can straighten the septum. In Sweden on average 24% of patients are dissatisfied 6 months after their septoplasty. The principal aim of this thesis was to investigate the clinical use of rhinomanometry in the septoplasty decision making process. This resulted in a checklist to increase the patients’ satisfaction with the operation.&lt;br/&gt;&lt;br&gt; We found that higher age and allergic rhinitis were factors giving significant odds for a spontaneous long term improvement of the nasal obstruction without septoplasty. That was in spite of septal deviation and pathological NAR. &lt;br/&gt;&lt;br&gt; In a study of 1000 patients with nasal obstruction we found that there has to be a certain NAR side difference between the nasal cavities before the patient could significantly assess it on a Visual Analogue Scale.&lt;br/&gt;&lt;br&gt; When rhinomanometry was performed in 9 participants every two weeks during 5 months, we found a high variability of the NAR, where tested subjects could move from pathological to normal. Intervention with topical budesonide treatment during a new five month period reduced both NAR and it’s variability significantly.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Undetermined&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Populärvetenskaplig sammanfattning på svenska &lt;br/&gt;&lt;br&gt; Nästäppa, som betyder svårigheter att andas med näsan är ett vanligt symtom i befolkningen, och en vanlig orsak till att patienter söker vård. Kronisk nästäppa är ett frekvent symtom (ca 40 % av vuxna) som ofta medför mun-andning med torra slemhinnor i munhåla och svalg samt snarkning till följd.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Nässkiljeväggen, septum, delar näshålan i två hålrum, som möts i nässvalget. På sidoväggarnas insida finns tre näsmusslor av ben, som hänger ned i hålrummet, vilket gör att näsan får en stor yta. Hela denna yta är täckt av slemhinna beklädd med flimmerhår. Alldeles innanför öppningarna sitter hårstrån som fungerar som ett grovt luftfilter. Små partiklar som ändå kommer in i näsan fastnar i slemmet och förs ner till svalget med hjälp av flimmerhåren. Slemhinnan är dessutom viktig för att göra inandningsluften fuktig. Luften värms upp tack vare ett nätverk av små blodkärl, som ligger under slemhinnan. Vårt luktorgan finns inbäddad i slemhinnan i näshålans tak. Inandningsluften behöver därför komma upp mot nästaket för att vi skall känna lukt. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Näsans trängsta parti, näsvalvet, påträffas någon centimeter in från näsöppningen. Näsan har en riklig nervförsörjning bestående av så kallade sympatiska, parasympatiska och sensoriska nerver. Nästäppa kan påverkas av överfunktion av parasympatiska nerver respektive underfunktion av sympatiska nerver. Fyllnad av blodkärlen i slemhinnan ger mindre plats i näshålan och man upplever nästäppa som sedan släpper när blodfyllnaden minskar.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I befolkningen finns en hög andel av personer med sneda nässkiljeväggar (=septumdeviation), studier har visat en förekomst av upp mot 50%. De flesta är medfödda och ger inga symtom alls. Men en septumdeviation som förtränger näskaviteten och ger nästäppa kan åtgärdas med en operation, septumplastik, där man rätar upp skiljeväggen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Att avgöra om en patient kan få nytta av en septumplastik är inte enkelt. Från det svenska kvalitetsregistret för septumplastik som är öppet för befolkningen (http://kvalitet.onh.nu/), ser man från perioden 2008-2010 att av de inregistrerade knappt 4000 septumplastiker som utfördes i Sverige, var 76% nöjda med sin operation 6 månader efteråt. Men det betyder samtidigt att 24% alltså nästan 1000 patienter, inte var nöjda med resultatet av sin operation. En hög andel av de som genomgår septumplastik i Sverige gör det i full narkos. Ibland är patienten inlagd på sjukhus ett dygn efter operationen. Och vanligtvis är patienten sjukskriven en vecka efter operationen. Det innebär således ett onödigt lidande och en betydande samhällsekonomisk kostnad för dessa 1000 patienter, som inte blir bra efter sin operation.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För bedömning av nästäppan, i syfte att hitta orsaken, har vi olika fråge-&lt;br/&gt;&lt;br&gt; formulärer om patientens subjektiva bedömning av nästäppans svårighetsgrad t.ex. VAS (Visual Analogue Scale), SNOT-22 (Sinonasal Outcome Test) eller NOSE (Nasal Obstruction Symptom Evaluation scale). Läkaren gör även en noggrann klinisk undersökning av hela näsan både före och efter avsvällning av slemhinnan. Enligt Svenskt Rhinologiskt Sällskaps konsensus 2004 bör man även göra en eller flera objektiva mätningar av näs-&lt;br/&gt;&lt;br&gt; flödesmotståndet som rhinomanometri, akustisk rhinometri, rinospiro-metri, PNIF (Peak Nasal Inspiratory Flow) m.fl. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Aktiv främre rhinomanometri innebär att luftflödet och lufttrycket mäts i en näskavitet i taget på en sittande patient som andas lugnt, och därefter beräknas näsandningsmotståndet. Metoden är känslig och störs av variationer i nässlemhinnans tjocklek. Man sväller därför av slemhinnan med nässpray för att mäta om ett högt motstånd är orsakat av ben-/broskförträngningar i näshålan, t.ex. en sned nässkiljeväg. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Akustisk rinometri innebär att man använder akustisk reflektion för att bestämma näskavitetens geometriska utseende. Det är en ren statisk undersökning som också görs på en sittande patient som andas lugnt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; PNIF och rinospirometri är enklare mätmetoder som ger mera grova mått på näsandningen, största inandningsflöde via näsan och andel som varje näskavitet bidrar med till näsandningen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Poiseuilles lag som vi minns från fysiken (Q = (π∆P/8ηL) R4, där Q = flödet, P = tryckgradienten, L = längden på röret och R = radien) beskriver flödet av en gas eller vätska i förhållande till radien på ett rör. Av formeln kan man se att en relativt sett liten minskning av radien ger en fyrapotens större flödesmotstånd. Detta är applicerbart på näsan ,där små inskränkningar av näskavitetens radie har stort inflytande på andningsmotståndet i näsan.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Många studier har visat att patienternas skattning av sin nästäppa överensstämmer dåligt med de kliniska fynden samt de objektiva mätningarna av näsflödesmotståndet. Detta komplicerar läkarens val av rätt patient till septumkirurgi. Det är därför av största vikt att de objektiva metoderna är bra, och att resultaten är reproducerbara och tillförlitliga. I våra fyra studier har vi granskat hur vi använder rhinomanometri i den kliniska verksamheten i utredningen av nästäppa och hur tillförlitliga resultaten är.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I studie I gjorde vi en långtidsuppföljning av 44 patienter som tidigare var på vår väntelista för septumplastik, men som av olika anledningar inte blev opererade. Vi fann att 36% inte längre hade några större problem med nästäppa efter 8 år. Speciellt patienter som hade näsallergi i sin sjukhistoria eller var äldre var spontant förbättrade.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I studie II granskade vi resultat från 1000 patienters rhinomanometriunder-sökning och deras subjektiva skattningar av nästäppan. Vi fann att 18% av patienterna paradoxalt nog upplevde den vida näskaviteten som mest täppt. Och vi fann att det bör vara en sidoskillnad i näsandningsmotståndet på över 20˚ i v2, som är ett matematisk mått på nästäppa, för att patienten ska kunna känna av denna sidoskillnad subjektivt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I studie III lät vi 9 personer mäta sitt näsandningsmotstånd varannan vecka i 5 månader för att se om resultaten var stabila över tid. Vi fann en stor varia-&lt;br/&gt;&lt;br&gt; tion av näsandningsmotståndet vilket gör det svårt att avgöra utifrån ett enda värde, om en patient lämpar sig för septumplastik.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie IV var en upprepning av studie III, men deltagarna använde dessutom kortisonnässpray under tiden för att behandla en eventuell underliggande inflammation i slemhinnan. Vi fick ett bättre reproducerbart resultat med minskad variabilitet av NAR och även 40% lägre NAR-värden. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har alltså gjort långtidsuppföljning på patienter med nästäppa som inte har opererats och sett att näsallergi och högre ålder var faktorer som ökade chansen att bli spontant förbättrade. Högre ålder kan således ibland motivera en ”vänta och se” strategi. Vi har granskat samband mellan subjektivt och objektivt näsandningsmotstånd och funnit ett samband mellan sidoskillnaderna mellan de två näshalvorna, som kan användas kliniskt i urvalet av patienter till septumplastik. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi studerade reproducerbarheten av näsandningsmotstånd och fann att den varierade en hel del. Vi försökte förbättra resultaten från rhinomanometrin genom att behandla med kortisonnässpray, och vi fick då mindre variabilitet i näsandningsmotståndet över tiden. Vi har således visat att aktiv främre rhinomanometri med mätning av näsand-ningsmotståndet i varje näshåla var för sig, har en viktig roll i utredningen av nästäppa. Den är också viktig för urvalet av patienter till näsoperation. Vi behöver dock ha normalvärden som utöver att vara längdjusterade även är åldersjusterade. Allt för att kunna bli bättre på att erbjuda rätt patient septumplastik, så att ännu flera blir nöjda med sin operation. Vi har slutligen gjort en checklista med en rad faktorer som kan förbättra urvalet och utfallet av septumplastik.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d35c3d04-e29d-4b20-a217-c26a65f01c99</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Helle_Thulesius.pdf">https://portal.research.lu.se/files/3359567/2440895.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1456679</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Otorhinolaryngology, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Rhinomanometry</topic> <topic>nasal obstruction</topic> <topic>nasal airway resistance</topic> <topic>septoplasty</topic> <topic>VAS</topic> <topic>xylometazoline</topic> <topic>budesonide</topic> <topic>topical nasal glucocorticosteroid</topic> </subject> <subject authority="lup"> <topic>Oto-rhino-laryngology</topic> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lunds University, Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-91-8</identifier> <identifier type="oldLupId">2439810</identifier> <part> <detail type="volume"> <number>2012:29</number> </detail> <extent unit="pages"> <total>117</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-05-04T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>d35c3d04-e29d-4b20-a217-c26a65f01c99</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:25:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:25:16+02:00</recordDateApproved> </recordInfo> </mods>

Its main role is to protect lung tissue from destruction by neutrophil elastase. In severe (PiZZ) AAT deficiency, there is an increased risk of emphysema, especially in smokers. The deficiency is caused by the retention and aggregation by polymerization of the AAT molecules in the liver, which increases the risk of neonatal cholestasis in infancy, and cirrhosis and hepatocellular carcinoma in adulthood. To investigate the prevalence of severe and moderate (PiSZ) AAT deficiency and follow its natural course, all 200,000 Swedish new-born children were screened in 1972-74. Among these, 128 individuals with severe and 55 with moderate AAT deficiency were identified. They and a group of controls were invited to a follow-up at the age of 30.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The participants answered a questionnaire including questions about occupation, smoking habits and respiratory symptoms. Pulmonary function tests and CT densitometry were performed. Blood samples were obtained to analyse liver enzymes and serum proteins.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The AAT-deficient individuals smoked less than the controls but the PiZZ individuals who had smoked had more respiratory symptoms than the other subgroups. The PiZZ current smokers had a lower FEV1/VC ratio and diffusion capacity for carbon monoxide compared to the other subgroups. As a group, the AAT-deficient individuals did not differ in respiratory symptoms, lung function or CT densitometry from the controls. The AAT-deficient individuals had normal levels of liver enzymes but mean ASAT and ALAT were significantly higher than in the control subjects.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; At the age of 30, individuals with severe (PiZZ) and moderate (PiSZ) AAT deficiency are healthy. However, smokers have more respiratory symptoms and alterations in lung function, which may be early signs of COPD. Compared to healthy controls, the AAT-deficient individuals had higher levels of liver transaminases.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a13a8c55-510f-4fb9-a532-a58534436a33</url> </location> </relatedItem> <originInfo> <publisher>Department of Respiratory Medicine and Allergology, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cohort</topic> <topic>screening</topic> <topic>alpha-1-antitrypsin</topic> <topic>lung function</topic> <topic>CT densitometry</topic> <topic>liver</topic> </subject> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-25-7</identifier> <identifier type="oldLupId">1370445</identifier> <part> <detail type="volume"> <number>2009:38</number> </detail> <extent unit="pages"> <total>136</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-02T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>a13a8c55-510f-4fb9-a532-a58534436a33</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:25:27+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:25:27+02:00</recordDateApproved> </recordInfo> </mods>

For children and adolescents physical activity is important not only in training of the neuromuscular system, coordination and balance, but in a wider perspective, for adopting a lifestyle that possibly reduces the risk of coronary artery disease, obesity, osteoporosis and other contributors to morbidity and mortality in the population. Previous studies have investigated the effects of moderate physical activity on fitness, obesity and bone health. The pre- and early pubertal period is usually considered as the best opportunity to enhance skeletal strength, but whether the same applies to neuromuscular function has seen less evaluation. In addition, muscular strength in pre-pubertal children has been shown to benefit from resistance training but whether similar benefits can be achieved by a moderately intense exercise programme is unclear. Hence, before we can recommend physical activity as prevention against low muscle strength and impaired neuromuscular function, we ought to show effects of intervention programmes on a population-based level with moderately intense exercise so that virtually all children can participate. School has been regarded as the ideal and perhaps only arena that could include all children within a defined population. This is the reason why this thesis was designed to present normative data for muscle strength and soft tissues in pre-pubertal children, and also to evaluate whether a general school curriculum-based moderately intense physical education intervention programme and mode of transportation to school could influence the development of neuromuscular function.&lt;br/&gt;&lt;br&gt; Materials and Methods: The participants in this thesis were collected from the Pediatric Osteoporosis Prevention (POP) cohort. A school-curriculum-based exercise intervention programme comprising 40 minutes of physical education per school day was initiated and 68 boys and 53 girls aged 6 to 8 from one school were included in the intervention group. Age- and gender-matched children in the control group (46 boys and 50 girls) from three neighbouring schools were assigned to the general Swedish school curriculum of 60 minutes of physical education per week. When evaluating the effect of the mode of school transportation, comparisons were made between children who reported to have walked or cycled to school, and those who had commuted by bus or car. Physical activity was measured objectively by accelerometers worn for four consecutive days. Accelerometer measurements, however, were not done until two years after study start. In the cross-sectional normative data report (paper IV) 246 boys and 190 girls aged 6 to 12 in Tanner stages I and II were included.&lt;br/&gt;&lt;br&gt; Measurements were conducted before any intervention was initiated. Neuromuscular function was assessed by concentric isokinetic peak torque of the knee extensors and flexors at 60° and 180°/s and with vertical jump height test. Total body soft tissue composition was evaluated by dual energy X-ray absorptiometry and body mass and stature by standard measurements. Level of physical activity was subjectively estimated through questionnaires. In the prospective part of the study (papers I, II and III), neuromuscular and soft tissue development was followed for one year in the intervention group and control group. &lt;br/&gt;&lt;br&gt; Results: The normative evaluation reported improved performance and higher values in all anthropometric measurements with advancing ages, and with no constant gender differences across the age groups. Both boys and girls with increased school-based physical educational classes had higher annual gains in different muscle strength indices, but not in vertical jump height, than the control group. Walking or cycling to school was not associated with beneficial gain in muscle strength indices or vertical jump height in either boys or girls. The level of physical activity measured by accelerometers was so high in these children that all reached the level recommended by the United Kingdom Expert Consensus Group of 60 minutes of moderate-to-vigorous daily physical activity. &lt;br/&gt;&lt;br&gt; Conclusion: Normative gender-specific data on muscle strength, lean and fat mass and vertical jump height show that in Swedish children aged 6 to 12 in Tanner stage I and II there seems to be an increase with age and no structural gender differences. Daily physical education classes in school could be used in pre-pubertal boys and girls as a strategy to increase muscle strength, at least in the short term. These findings suggest increased physical education in pre-pubertal children as one possible strategy to improve neuromuscular function on a population level in society. In contrast, the mode of school transportation seems not to influence the measured traits, at least not in young children with a generally high level of everyday physical activity.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Bakgrund: Regelbunden fysisk aktivitet och träning anses som en livsstilsfaktor som kan förbättra muskelstyrkan, skelettet, konditionen och kroppssammansättningen. För barn och ungdomar är fysisk aktivitet inte bara viktigt för att träna de muskulära funktionerna, koordinationen och balansen. I ett större perspektiv kan en fysiskt aktiv livsstil också minska risken för hjärt- och kärlsjukdomar, fetma, benskörhet och en rad andra sjukdomar i samhället. Tidigare undersökningar har studerat effekterna av medelintensiv fysisk aktivitet beträffande kondition, fetma och skelettets hållfasthet. Tiden innan och under tidig pubertet anses då allmänt som det bästa tillfället att förbättra skelettets hållfasthet. Om detta även gäller för muskelfunktionen är mindre utrett. Styrketräning hos barn har t.ex. visat sig ge positiva resultat på muskelstyrka men om motsvarande effekt kan uppnås av ett medelintensivt träningsprogram är oklart. Innan man rekommenderar fysisk aktivitet generellt i samhället för att förebygga svag muskelstyrka bör man därför visa att även allmänna träningsprogram, på en nivå så att alla barn klarar att delta, har effekt. Skolan har då ansetts vara den ideala, och möjligen den enda arenan, där alla barn kan nås. Mot denna bakgrundskunskap har denna avhandling utformats för att dels presentera normalvärden för muskelstyrka och mjukdelsvävnad hos barn före puberteten, och dels utvärdera om ett medelintensivt interventionsprogram i form av utökad skolgymnastik påverkar utvecklingen av muskelfunktionen hos barn. Avhandlingen undersöker även om det är gynnsammare för muskelutvecklingen att gå eller cykla till skolan jämfört med om man åker bil eller buss. &lt;br/&gt;&lt;br&gt; Material och metoder: Försökspersonerna som medverkade i denna avhandling hämtades från den så kallade Bunkeflostudien, eller på engelska, the Pediatric Osteoporosis Prevention (POP) Study. I denna studie genomfördes ett s.k. interventionsprogram. En grupp barn (68 pojkar och 53 flickor) deltog i träningsgruppen som fick utökad fysisk aktivitet i form av 40 minuters daglig skolgymnastik, d.v.s. 200 minuter per vecka. Dessa jämfördes med en kontrollgrupp, som bestod av 46 pojkar och 50 flickor, som erhöll 60 minuter skolgymnastik per vecka. För att utvärdera effekten av träningen jämfördes förändringen i muskelstyrka, hopphöjd och kroppssammansättning mellan de två grupperna under det året som studien pågick. Den fysiska aktivitetsnivån utvärderades med ett frågeformulär. För att utvärdera hur skoltransport påverkar utvecklingen av muskelfunktionen delades barnen in i två grupper baserade på hur de hade valt att ta sig till skolan under ett år; en grupp som gick eller cyklade och en grupp som åkte bil eller buss. Fysisk aktivitetsnivå uppskattades dels med ett frågeformulär och dels med en mätare som barnen bar under fyra dagar, en s.k. accelerometer. På så sätt erhölls ett objektivt mått på hur mycket barnet rört sig under de fyra dagarna. &lt;br/&gt;&lt;br&gt; För att kunna redovisa normala värden för muskelstyrka, hopphöjd och kroppssammansättning i åldrarna 6 till 12 år inkluderades ett större antal barn som alla mättes innan man startade den ökade skolgymnastiken. I denna grupp ingick 246 pojkar och 190 flickor där de flesta barnen var förpubertala men där ett fåtal hade nått tidig pubertet. Mätningarna i samtliga delarbeten utgjordes av tester av muskelstyrka i knäets sträckar- och böjarmuskulatur samt hopphöjd. Dessutom mättes kroppssammansättning med lågdosröntgen, dels mängden ”lean body mass”, som i huvudsak består av muskulatur, och dels mängden fett. Vikt och längd mättes med standardutrustning. &lt;br/&gt;&lt;br&gt; Resultat: Både pojkar och flickor med daglig skolgymnastik hade större ökning av de olika muskelvariablerna under ett år. Däremot påverkades inte hopphöjden av den ökade skolgymnastiken. Det verkar inte heller som om vare sig pojkar eller flickor som gick eller cyklade till skolan erhöll en mer gynnsam utveckling av muskelfunktionen jämfört med de barn som åkte bil eller buss. Samtliga barn i studien hade höga fysiska aktivitetsnivåer. Normalvärdena för muskelstyrka, hopphöjd och kroppssammansättning hos barn i åldrarna 6 till 12 år visade att samtliga variabler ökar med ökande ålder utan att man fram till puberteten kunde se några skillnader mellan pojkar och flickor. &lt;br/&gt;&lt;br&gt; Slutsats: Fram till puberteten ökar muskelstyrka närmast linjärt hos både pojkar och flickor utan att man ser några könsskillnader. Daglig skolgymnastik före puberteten kan vara en metod att öka muskelstyrka hos båda könen, i all fall i ett kortare tidsperspektiv. Dessa fynd antyder att utökad skolgymnastik hos förpubertala barn kan vara en möjlig angreppspunkt för att förbättra muskelfunktionen. Däremot verkar inte valet av transportmedel till skolan påverka utvecklingen av muskelfunktionen i dessa åldrar.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/76686ae0-7824-40f9-a5e3-ddcb199fbaf2</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>children</topic> <topic>physical activity</topic> <topic>exercise</topic> <topic>isokinetic muscle strength</topic> <topic>vertical jump height</topic> <topic>normative</topic> <topic>intervention</topic> <topic>school transport</topic> <topic>DXA</topic> <topic>anthropometry</topic> <topic>fat mass</topic> <topic>lean mass</topic> <topic>weight</topic> <topic>height</topic> <topic>body mass index</topic> <topic>girls</topic> <topic>boys</topic> <topic>pre-pubertal</topic> </subject> <subject authority="lup"> <topic>Orthopaedics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-80-8</identifier> <identifier type="oldLupId">1886882</identifier> <part> <detail type="volume"> <number>2011:32</number> </detail> <extent unit="pages"> <total>134</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-04-28T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>76686ae0-7824-40f9-a5e3-ddcb199fbaf2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:25:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:25:31+02:00</recordDateApproved> </recordInfo> </mods>

The human TLR family presently comprises ten members (TLR1-TLR10), each with distinct properties. Although the TLRs protect the host from infection, they have become increasingly implicated in the pathogenesis of various inflammatory diseases, including asthma and allergy. The aim of this thesis was to characterize the presence and function of TLRs in different cell types involved in upper airway inflammation, with special emphasis on recurrent tonsillar infection and allergic rhinitis. We also sought to map cellular and molecular changes occurring as a result of allergen-specific immunotherapy.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the first two studies, a distinct expression of TLRs was demonstrated in subsets of B and T lymphocytes isolated from human tonsils. The expression levels seemed to be affected by ongoing tonsillar infection. This was most evident in T cells. By studying the functional activity of the expressed receptors, it was found that the corresponding ligands promoted B cell activation. These data indicate that TLRs have a direct role not only in activation of the innate part of our immune system, but also of the adaptive branch.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the next two studies, presence of the virus-sensing receptors TLR3, TLR7 and TLR9 was shown in eosinophils. Stimulation with the cognate ligands gave rise to an activation manifested by an increased eosinophil survival, release of damaging mediators and ability to migrate to inflamed areas. It was also found that the response was higher in atopic patients with allergic rhinitis than in healthy subjects, and in the presence of a Th2-like cytokine milieu. Thus, activation of eosinophils via these TLRs might engender a link between viral infection and allergic exacerbations. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the following work, the effect of nasal administration with the TLR9 agonist CpG was described in healthy subjects and in patients with allergic rhinitis. CpG exposure resulted in an increased nasal resistance, production of nasal nitric oxide, infiltration of inflammatory cells and release of pro-inflammatory Th1-type cytokines. These responses were generally more marked among the healthy subjects, most likely due to the ongoing persistent inflammation seen in the allergic group. Taken together, these results show that CpG induces a local inflammation that skews the immune response towards a Th1-like phenotype. &lt;br/&gt;&lt;br&gt; Lastly, cellular and molecular effects induced by rush immunotherapy were analyzed in patients with birch pollen-induced allergic rhinitis. The clinical improvements seen as a result of three years of treatment were mirrored by several changes in antibody and receptor levels. Of these, a reduction in serum allergen-specific IgE antibodies, correlating with cell-bound IgE and IgG expression, along with a general activation of T cells were most prominent. The novel findings in this report included a shift in monocyte populations and decrease in levels of TLR2 and TLR4. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To summarize, the results presented in this thesis demonstrate a role for TLRs in lymphocyte and eosinophil biology, as well as an involvement in tonsillar and allergic inflammation. Although their exact role in airway inflammation is unclear, the TLR system holds great promise in the development of new therapeutic alternatives for allergic and inflammatory diseases.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d284ec3b-6368-4755-9fef-f9b606b848bd</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Elektronisk_reg_av_avhandlingen.pdf">https://portal.research.lu.se/files/3363907/1301537.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">715503</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Otorhinolaryngology, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>lymphocytes</topic> <topic>peripheral blood</topic> <topic>allergic rhinitis</topic> <topic>tonsils</topic> <topic>eosinophils</topic> <topic>specific allergen immunotherapy</topic> </subject> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-11-0</identifier> <identifier type="oldLupId">1301530</identifier> <part> <detail type="volume"> <number>2009:24</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-03-20T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>d284ec3b-6368-4755-9fef-f9b606b848bd</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:25:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:25:40+02:00</recordDateApproved> </recordInfo> </mods>

The overall aim of this study was to investigate the female characters in five of the works that have had the most influence on the development of the indigenista novel: Aves sin nido (1889) by Clorinda Matto de Turner, Raza de bronce (1918) by Alcides Arguedas, Huasipungo (1934) by Jorge Icaza, El mundo es ancho y ajeno (1941) by Ciro Alegría, and Los ríos profundos (1958) by José María Arguedas. &lt;br/&gt;&lt;br&gt; The representations of and the roles played by the female characters in the five novels were systematically studied, individually and in comparison to each other. The purpose was to investigate whether the female characters function primarily as representatives of a certain ideological point of view and, thus, are to be regarded as stereotypes, or if they are complex characters. Moreover, their role in the novels was studied from the perspective of Mikhail Bakhtin’s notion of “the destruction of the idyll”.&lt;br/&gt;&lt;br&gt; The study found that the female characters play an inconspicuous part in Raza de bronce, Huasipungo and El mundo es ancho y ajeno. Contrastingly, in Aves sin nido and Los ríos profundos, there are several female characters who play a more prominent part. Nevertheless, in all of the works studied, the female characters were found to function more as types than as fully developed characters. &lt;br/&gt;&lt;br&gt; A recurring motif in the novels of the study is the subjection of the indigenous female characters to violence or sexual abuse by a white landowner and his henchmen, or by a family member. The analysis found that there is a recurring type of female character in the novels: the female victim. The female victim of the works studied is normally of indigenous origin. &lt;br/&gt;&lt;br&gt; The study also found that the indigenous female characters are portrayed differently than other female characters. They are consistently presented as the type of character that this study has termed “idyllic”, the most prominent traits of which are simplicity, naturalness, and the possession of a strong bond to family and home. In contrast, the creole women and mestizas are often part of the modern sphere. &lt;br/&gt;&lt;br&gt; The female character of the idyllic type plays a symbolic part in the novels, as the guardian of the survival of the family and the traditional society. When this figure becomes subject to different kinds of abuse, it is not only the individual character who comes under attack but also everything that she symbolizes, which, in the indigenista novel, is contrasted with the modern capitalist society.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5f75eef0-7c91-49c6-bf3b-392a78fa9315</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Tesis_Ingela_Johansson_08.pdf">https://portal.research.lu.se/files/3368152/1025506.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">821683</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Språk- och litteraturcentrum, Lunds universitet</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">spa</languageTerm> </language> <subject> <topic>Aves sin nido</topic> <topic>female character</topic> <topic>ideology</topic> <topic>Raza de bronce</topic> <topic>Huasipungo</topic> <topic>El mundo es ancho y ajeno</topic> <topic>Los ríos profundos</topic> <topic>Bakhtin</topic> <topic>roman à thèse</topic> <topic>indigenista novel</topic> <topic>idyll</topic> <topic>victim</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Études Romanes de Lund</title> </titleInfo> <identifier type="issn">0347-0822</identifier> <identifier type="isbn">978-91-628-6615-0</identifier> <identifier type="oldLupId">1025469</identifier> <part> <detail type="volume"> <number>80</number> </detail> <extent unit="pages"> <total>202</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-03-01T10:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>5f75eef0-7c91-49c6-bf3b-392a78fa9315</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:25:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:25:58+02:00</recordDateApproved> </recordInfo> </mods>

The retinopathy was associated with higher diastolic and systolic blood pressure, weight and body mass index (BMI). The 5-year incidence of developing retinopathy was 6.9%.&lt;br/&gt;&lt;br&gt; In the second part of the study electrophysiological alterations was found in full- field ERG and multi focal ERG in newly onset type 2 diabetes patients even before any vascular retinopathy was detectable on fundus photography. Alterations were also verified before visual detoriation in patients with ischemic maculopathy and long duration of diabetes. &lt;br/&gt;&lt;br&gt; Conclusion: Blood pressure appears to be a major concern in the development of retinopathy in subjects with impaired fasting glucose, IFG. The incidence of retinopathy was, however low in these subjects who had received recommendations regarding diet and lifestyle.&lt;br/&gt;&lt;br&gt; The full-field and multifocal electroretinography demonstrate early alterations of the retinal function identified before any retinopathy is visible on fundus photography. In future electrophysiological examinations may be valuable to follow these alterations in the natural course of the disease and to evaluate effect of treatment including the neuroretina.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1bcf63fa-278a-4669-bc38-c1108f2be4eb</url> </location> </relatedItem> <originInfo> <publisher>Department of Ophthalmology, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>diabetic retinopathy</topic> <topic>full-field electroretinography</topic> <topic>multifocal electroretinography</topic> <topic>impaired fasting glucose</topic> </subject> <subject authority="lup"> <topic>Ophthalmology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-96-2</identifier> <identifier type="oldLupId">1716783</identifier> <part> <detail type="volume"> <number>2010:80</number> </detail> <extent unit="pages"> <total>49</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-12-10T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>1bcf63fa-278a-4669-bc38-c1108f2be4eb</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:01+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:01+02:00</recordDateApproved> </recordInfo> </mods>

This thesis discusses changes is microvascular flow, permeability and plasma volume (PV) loss after experimental or surgical trauma and experimental sepsis. We evaluated the effect of blunt skeletal muscle trauma itself and thereafter treatment with prostacyclin (PGI2) on PV-loss, transcapillary escape rate (TER) of 125I-albumin and cytokine release. In experimental sepsis, we studied the importance of charge for microvascular permeability and observed the effectiveness of albumin versus Ringer&apos;s acetate compared to a hemorrhage model. Perioperatively, we evaluated changes in the sublingual microcirculation in patients undergoing major abdominal surgery, using Sidestream Darkfield-imaging (SDF) in relation to outcome.&lt;br/&gt;&lt;br&gt; Skeletal muscle trauma caused PV-loss, increase in permeability and cytokine release and PGI2-treatment attenuated these changes. &lt;br/&gt;&lt;br&gt; Sepsis led to a breakdown of the negatively charged glycocalix, which is probably important for the normally low permeability of albumin. &lt;br/&gt;&lt;br&gt; The plasma volume expanding effect of albumin as compared to Ringer&apos;s acetate was independent of the state of permeability. &lt;br/&gt;&lt;br&gt; Perioperative changes in the sublingual microcirculation during major abdominal surgery are minor with no correlation to outcome or parameters reflecting global oxygen delivery.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/2b4e51cd-0c7a-4719-9b9d-970ff57625c1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Peter_Bansch.pdf">https://portal.research.lu.se/files/3368883/3809508.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5678641</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Anaesthesiology and Intensive Care</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>microcirculation</topic> <topic>prostacyclin</topic> <topic>plasma vilume</topic> <topic>trauma</topic> <topic>sepsis</topic> <topic>sidestream darkfield imaging</topic> <topic>albumin</topic> <topic>volume expansion</topic> <topic>transcapillary escape rate</topic> <topic>glycocalyx</topic> <topic>charge</topic> </subject> <subject authority="lup"> <topic>Anesthesiology and Intensive Care</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-36-9</identifier> <identifier type="oldLupId">3806499</identifier> <part> <detail type="volume"> <number>2013:66</number> </detail> <extent unit="pages"> <total>112</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-06-07T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>2b4e51cd-0c7a-4719-9b9d-970ff57625c1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:09+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:09+02:00</recordDateApproved> </recordInfo> </mods>

Within this framework, the dissertation explores two main sets of questions. First, utilizing a contextual understanding of genre, the dissertation analyzes how the films were produced, exhibited, and censored, what position and status they had, and where the borders were understood to be to kindred types of film, such as exploitation and pornography. Second, the norms and ideas about sexuality that the films construct are explored from a social constructionist perspective and put in historical context. Apart from the films themselves, the material used consists of censorship records, archival material, and articles and reviews from the daily press and the trade press. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The study demonstrates that the sex education film has always been a delicate genre, and that this delicacy is related to the medium and to the fact that cinema is part of the commercial market. The sex education film came to Sweden through imported films during the silent era and was relatively common at Swedish movie theaters from the 1920s to the early 1970s. Very quickly, it became a contested genre thought to be in need of regulation, which can be seen in the censorship procedures. For instance, until the 1950s, screenings were often restricted through gender segregation. When film censorship was liberalized in the 1960s, sex education films could show more than before, and when the films in the sexually explicit Language of Love series (1969–1972) were released, their relationship to pornography became a central point of discussion. The changing views on using film in school sex education are also examined. Here, it is shown that if film was seen as a potentially helpful tool in the 1920s and 1930s, this view had changed into a more skeptical position by the early 1970s. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the analysis of the content of the films, only Swedish examples are studied. In the first group of theatrically shown films of this kind, which appeared in the 1940s and 1950s, sexuality is represented as problematic through the themes of venereal disease and abortion. Here, casual sex is seen as immoral and abortion is condemned. At the same time, the films display how traditional and modern views on sexuality and gender were under negotiation during this period. While reproduction was the dominating perspective in school films well into the 1970s, the Language of Love films display a radically different perspective on sex, not least because of their focus on sexual pleasure. However, while the films advocate a liberal idea about sexuality according to which science leads to liberation, a focus on romantic long-term relationships can also be noted. Throughout the period, there is an emphasis on rationality and science and on a secular perspective on sex in which love is seen as more important than matrimony. In this way, the films in general reflect a strong belief in modernity and progress that was characteristic of Sweden during the welfare era.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/a8ca1aac-dce0-4e3b-9f9a-8eaf0c311674</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Sex education film</topic> <topic>sexuality and Swedish cinema</topic> <topic>censorship</topic> <topic>genre</topic> <topic>exploitation</topic> <topic>pornography</topic> <topic>gender</topic> <topic>Swedish welfare state</topic> <topic>“Swedish sin”</topic> <topic>Language of Love films</topic> <topic>school film</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Critica Litterarum Lundensis</title> </titleInfo> <identifier type="issn">1651-2367</identifier> <identifier type="isbn">978-91-7473-418-8</identifier> <identifier type="oldLupId">3288204</identifier> <part> <detail type="volume"> <number>11</number> </detail> <extent unit="pages"> <total>426</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-01-19T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>a8ca1aac-dce0-4e3b-9f9a-8eaf0c311674</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:16+02:00</recordDateApproved> </recordInfo> </mods>

The mechanistic-empirical pavement design guide (M E PDG), the incremental-recursive mechanistic-empirical CalME model (CalME), and the PErmanent Deformation of asphalt concrete layer for ROads (PEDRO) model generally showed both useful features and limitations. The M E PDG results were more accurate at the lowest material input data quality level (level 3) than at the highest (level 1). The main cause was probably the demonstrated inaccuracy of the predicted dynamic modulus at level 3 compared with measured level 1 results, and the M E PDG calibration at level 3. The CalME underestimated the permanent deformation in the semi-rigid section due to its response modeling sensitivity to overall pavement stiffness. Further, the results indicated that the relation between elastic and plastic material properties may change throughout the pavement life. The PEDRO model behavior due to lateral wander and observed field temperatures was reasonable. The zero shear rate viscosity assessment method for asphalt concrete, utilized in PEDRO, should be further evaluated. All models produced reasonable permanent deformation results although further validation and calibration is recommended before employment for pavement design purposes in Sweden.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; De allra flesta av oss bilister har någon gång kört på en väg med tydliga spår i vägytan. Man märker tydligt hur både komforten och säkerheten minskar eftersom möjligheten att styra fordonet försämras. Dessutom försämras trafiksäkerheten ytterligare när regn eller snö ansamlas och orsakar vattenplaning eller halka. Därför får de gradvis framväxande spåren inte bli för djupa. Problemet hanteras genom att utföra underhåll eller att bygga ny väg, vilket årligen kostar Trafikverket ca åtta respektive ca 11 miljarder kronor. För att förhindra framtida problem måste man säkerställa att åtgärden är långsiktigt hållbar. Samtidigt vill man inte överdimensionera av ekonomiska och miljömässiga skäl. Därför används modeller för att beräkna hur spårbildningen utvecklas vid olika trafiklaster och klimat i den planerade vägkonstruktionen. På det sättet kan man välja de material och lagertjocklekar som minimerar kostnaden på lång sikt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Spårbildning orsakas av en kombination av dubbdäckens nötning samt permanenta deformationer både i asfaltlager och underliggande lager av krossat bergmaterial och jord. Denna avhandling fokuserar på modellering av permanenta deformationer i asfaltlager, som består av efterpackning, eller förtätning, och flytning som innebär att materialet trycks ned i hjulspåret och trycks upp vid sidan. Permanenta deformationer i asfaltlager orsakas av faktorerna trafik, material, överbyggnadskonstruktion och klimat. Trafiken påverkar genom antalet belastningar, storleken på lasten och belastningstrycket mellan däck och vägyta. Material och konstruktion spelar in genom att olika typer av asfaltmaterial placerade på olika djup i vägkonstruktionen skapar olika förutsättningar för att motstå de permanenta deformationerna. Klimatet påverkar genom att asfalten, som består av krossat berg och råoljeprodukten bitumen, har mekaniska egenskaper som är mycket temperaturberoende.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De modeller som utvärderades i denna avhandling är de amerikanska M-E PDG och CalME, och den svenskutvecklade PEDRO. De aspekter som studerades var metoder för att anskaffa indata, modellering och kalibrering. Insamling av indata är viktig eftersom dess kvalitet begränsar resultatens kvalitet. Modelleringen och dess element utvärderades med avseende på dess överensstämmelse med observerat beteende på verkliga vägar. Slutligen studerades även omfattningen av kalibreringen, som är en empirisk korrektion som korrelerar modellresultat med observerat spårdjup.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Utvärderingen utfördes genom att ett antal vägsektioner bestående av olika material utsattes för olika trafikbelastningar och klimat. Dessa uppgifter har sedan använts som indata till modellerna. Modellresultaten jämfördes sedan med observerat spårdjup från de aktuella vägsektionerna. Utvärderingen utfördes med två motorvägsektioner utsatta för verkliga trafik- och klimatförhållanden, och med två fullskalesektioner utsatta för intensiv mekanisk belastning av en maskin som simulerar tunga fordon (Heavy Vehicle Simulator). Modellerna kunde generellt sett beräkna de observerade permanenta deformationerna under vissa förhållanden. De utvärderade modellerna uppvisade därmed både rimliga och användbara egenskaper men även vissa begränsningar. Ytterligare validering under svenska förhållanden vore värdefull för att implementera delar av modellerna för dimensionering i Sverige.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e44c627a-b067-4f94-a14e-6d411cebbb78</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Erik_Oscarsson_kappa.pdf">https://portal.research.lu.se/files/3372849/1939373.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2259688</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Technology and Society, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>permanent deformation</topic> <topic>modeling</topic> <topic>Mechanistic-Empirical</topic> <topic>rutting</topic> <topic>asphalt concrete</topic> <topic>full-scale pavements</topic> </subject> <subject authority="lup"> <topic>Infrastructure Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-083-8</identifier> <identifier type="oldLupId">1884775</identifier> <part> <extent unit="pages"> <total>208</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-04-27T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>e44c627a-b067-4f94-a14e-6d411cebbb78</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:19+02:00</recordDateApproved> </recordInfo> </mods>

Previous studies reveal a high risk for HCM related cardiac events including sudden cardiac death (SCD) during childhood, with a peak incidence of up to 10% during the first two decades of life. HCM remains the most common cause of sudden cardiac death in young people and athletes, probably due to fatal arrhythmias mainly caused by structural and functional changes in the myocardium leading to increased risk for major cardiac events. In young athletes, the distinction between physiological and pathological hypertrophy is often very challenging. The diagnosis of HCM in childhood is more difficult in its early phases, due to the progressive nature of the disease and the lack of HCM symptoms. The increasing population with HCM genotype with little or no detectable myocardial hypertrophy along with the increased risk for cardiac events even in these individuals are important aspects that emphasize the stringent need to improve early diagnosis of HCM in the young. In these studies, we sought to investigate indices of early cardiovascular changes in young individuals with or without myocardial hypertrophy on echocardiography. &lt;br/&gt;&lt;br&gt; Study I showed altered diastolic function both in HCM and HCM-risk individuals vs. controls and young athletes. There were altered microvascular responses to acetylcholine, indicating an early endothelial dysfunction present in both the HCM-risk and HCM patients, measured by laser Doppler of peripheral circulation. These microvascular changes were associated with abnormalities in diastolic myocardial function measured by TDI. &lt;br/&gt;&lt;br&gt; Study II demonstrated decreased myocardial perfusion (MP) during adenosine induced hyperemia in non-fibrotic myocardium even without diastolic dysfunction in young HCM patients, but not subjects at risk or controls, indicating that microvascular disease can be the cause of MP decrease. &lt;br/&gt;&lt;br&gt; Study III showed decreased regional perfusion in hypertrophied compared to non-hypertrophied myocardium and even lower perfusion in areas of fibrotic, hypertrophied myocardium in young HCM patients. The adenosine stress-induced hypoperfused areas were found larger than regions with LGE (fibrosis), indicating that hypoperfusion may be a more sensitive marker of diseased myocardium. &lt;br/&gt;&lt;br&gt; Study IV suggests adverse changes of circulating biomarkers reflecting myocardial matrix remodeling, microfibrosis and vascular endotheliopathy in the early stage of hypertrophic cardiomyopathy in the young. &lt;br/&gt;&lt;br&gt; Study V showed the superiority of the 2-parameter 12-lead A-ECG score, which is significantly more sensitive and specific than pooled, age-specific conventional ECG criteria for detecting MYBPC3-HCM and in distinguishing such patients from healthy controls, including endurance-trained athletes.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Populärvetenskaplig sammanfattning&lt;br/&gt;&lt;br&gt; Familjär hypertrof kardiomyopati (HCM) är den vanligaste ärftliga hjärtsjukdomen som ärvs autosomalt dominant, dvs. ca 50% risk för varje barn i den drabbade familjen. Tidigare studier har visat hög risk för HCM relaterade tillbud inklusive plötslig hjärtdöd (SCD) under barndomen, med en incidens upp till 10 % under de två första decennierna i livet. Fortfarande är HCM den vanligaste orsaken till plötslig hjärtdöd (Sudden Cardiac Death, SCD) hos unga människor och idrottare, sannolikt till följd av allvarlig arytmi, orsakad av strukturella förändringar i hjärtmuskeln. Sjukdomen HCM medför gradvis förtjockning av vänster kammares hjärtmuskelväggar, och med tiden bildas sjukliga substrat i hjärtat som ökar risken för allvarliga hjärthändelser. På grund av sjukdomens progressiva karaktär, kan den vara svår att hitta i yngre åldrar. Att skilja träningsinducerad från sjukdomsassocierad förtjockning av hjärtmuskelväggarna är ofta mycket svårt i de tidiga faserna av HCM, speciellt i unga år. I modern tid måste vi hantera en ökande befolkning med HCM-genotyp men med normal fenotyp och bättre kunna identifiera de faktorer som indikerar allvarligare sjukdomsprogress, samt förbättra vår förmåga att förutse dessa faktorer i tidigare stadier av sjukdomen.&lt;br/&gt;&lt;br&gt; Syftet med dessa studier har varit att med multimodal bild- och funktionsdiagnostik fokusera på tidiga kardiovaskulära förändringar i presymtomatisk fas av HCM hos unga.&lt;br/&gt;&lt;br&gt; Studie I visade förändrad diastolisk funktion hos HCM men också hos HCM-risk individer. Vi påvisade även förändrad mikrovaskulär reaktivitet på acetylkolin, vilket tyder på tidigt förekommande endoteldysfunktion, både hos unga presymtomatiska HCM-risk och HCM patienter, mätt med laser Doppler i perifer cirkulation. De mikrovaskulära förändringarna uppvisade samband med påverkad diastolisk hjärtmuskelfunktion. &lt;br/&gt;&lt;br&gt; Studie II visade minskade myokardiell perfusion (MP) vid adenosin-provokation i icke-fibrotisk hjärtmuskel hos unga HCM patienter, men inte hos HCM-risk individer eller kontroller, tydande på att mikrovaskulär sjukdom kan vara orsaken till minskad MP.&lt;br/&gt;&lt;br&gt; Studie III visade minskad regional genomblödning i förtjockad jämfört med icke- förtjockad hjärtmuskel och ännu lägre genomblödning i områden med fibrotisk och förtjockad hjärtmuskel hos unga HCM patienter. Adenosin-inducerad stress visade att hypoperfunderade områden var större än områden med LGE (fibros), indikerande att hypoperfusion kan vara en känsligare markör för att identifiera sjuk hjärtmuskel vid HCM.&lt;br/&gt;&lt;br&gt; Studie IV påvisade förändrade nivåer av cirkulerande biomarkörer vilka återspeglar remodellering av hjärtmuskeln, microfibros, vaskulära förändringar och endotel påverkan även i ett tidigt skede av HCM hos unga. &lt;br/&gt;&lt;br&gt; Studie V visade att en 2-parameter kombination av 12-avlednings A-EKG var betydligt mer känsligt och mer specifikt jämfört med åldersspecifika, konventionella EKG-kriterier för detektion av MYBPC3-HCM och att särskilja dessa patienter från friska kontroller samt ungdomsatleter.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6ce1549a-a5e2-4888-bac2-19e9e7c17fbc</url> </location> </relatedItem> <originInfo> <publisher>Paediatrics, Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>A-ECG.

However, the rate of disease progression is highly variable both within and between HIV-1 and HIV 2, but the mechanisms involved in modulating the rate of disease progression remain poorly understood. Host genetics account for some of the variation within each virus type but viral genetic factors were recently described to be more important than previously anticipated. The aim of this thesis work was to investigate the association between some viral genetic factors and disease progression. More specifically, we investigated the impact of HIV-1 subtype and HIV-2 evolution on disease progression.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The HIV-1 subtype was determined based on sequencing of the C2-V3 region of env. The rate of disease progression was compared among 139 individuals from Guinea-Bissau infected with the three major subtypes/CRFs; A3, CRF02_AG and A3/02. Infection with A3/02, a recombinant form with a break-point in the C2 region, was associated with a faster disease progression compared with infection with sub-subtype A3. Infection with CRF02_AG resulted in an intermediate disease progression. Our results suggested that recombinant forms may be more aggressive than their parental variants. Near full-length sequencing of six A3/02 samples, showed that the previously identified recombination break-point in the C2 region, was the only break-point shared by all six samples, identifying this region as a possible modulator of disease progression.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; We also investigated the evolution of the HIV-2 V1-C3 region of env in 16 individuals stratified as fast or slow progressors based on CD4+ T cell dynamics. We found that disease progression as defined by CD4+ T cell level, rather than CD4+ T cell decline rate, was associated with evolutionary parameters. Most strikingly, a fast disease progression, as defined by CD4+ T cell level, was associated with an almost twice as high evolutionary rate compared with a slow disease progression. This difference was accounted for by higher rates of both nonsynonymous and synonymous substitutions, indicating that viral generation time and/or replication rates are the main modulators of the HIV-2 evolutionary rate. Fast and slow disease progression was also distinguished by different evolutionary patterns of Env glycosylation. The evolution of the other investigated Env molecular properties did not differ between progressor groups and was suggested to be more limited than what has previously been described for HIV-1.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; This thesis work increases our understanding of the HIV pathogenesis by adding insight into previously unknown characteristics of HIV-1 and HIV-2 pathogenesis. Further work, building on these data, may reveal important predictors of disease progression and identify new targets for drug development.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/fae4485f-8bfd-478b-aa69-63cf865b724e</url> </location> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Basic Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-091-3</identifier> <identifier type="oldLupId">4935765</identifier> <part> <detail type="volume"> <number>2015:11</number> </detail> <extent unit="pages"> <total>87</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-01-30T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>fae4485f-8bfd-478b-aa69-63cf865b724e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:22+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:22+02:00</recordDateApproved> </recordInfo> </mods>

However, limitations include insufficient amount of suitable donor &lt;br/&gt;&lt;br&gt; material and donor site morbidity. The aim of the present thesis was to study alternative nerve grafts, &lt;br/&gt;&lt;br&gt; i.e. allo- and xenografts, in rats and mice. Cellular grafts will evoke a rejection in the host aiming at &lt;br/&gt;&lt;br&gt; destroying the graft. Thus, different strategies to suppress or avoid rejection were studied.&lt;br/&gt;&lt;br&gt; Treatment with the immunosuppressant FK506 increased axonal outgrowth after a nerve crush lesion, &lt;br/&gt;&lt;br&gt; but did not improve axonal outgrowth in autologous nerve grafts in rats.&lt;br/&gt;&lt;br&gt; The new strategy of costimulation blockade that inhibits T-cell activation prohibited rejection of nerve &lt;br/&gt;&lt;br&gt; allografts in mice in the short term. Rejection of grafts in placebo-treated mice impeded axonal out-&lt;br/&gt;&lt;br&gt; growth. In the long-term, costimulation blockade inhibited rejection and resulted in an improved &lt;br/&gt;&lt;br&gt; myelination of regenerated axons. A higher target muscle weight indicated less denervation atrophy &lt;br/&gt;&lt;br&gt; and thus improved nerve regeneration after costimulation blockade.&lt;br/&gt;&lt;br&gt; To avoid immunosuppression altogether acellular nerve allo- and xenografts were studied. The best &lt;br/&gt;&lt;br&gt; axonal outgrowth was observed in allografts. The axonal outgrowth in xenografts was influenced by &lt;br/&gt;&lt;br&gt; the combination of host/donor species.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, costimulation blockade inhibits rejection of nerve allografts and allows axonal outgrowth. &lt;br/&gt;&lt;br&gt; However, for reconstruction of an isolated severe nerve injury with a defect, the use of acellular nerve &lt;br/&gt;&lt;br&gt; allografts is a promising strategy.

The generation about to establish themselves on the labour market at this time were born in the mid seventies. They experienced unemployment and welfare&lt;br/&gt;&lt;br&gt; dependency to a considerably higher extent than any previous generation in the modern Swedish welfare state. Despite the recovery of the Swedish economy a group of young adults, now in their mid thirties, simply could not find a way to either work, education or self-support. The aim of this dissertation is to study both actual living conditions and the experience of being unemployed and a social assistance recipient among those who remained in benefit dependency after the welfare crisis in the 1990s. The methodological approach is a combination of qualitative and quantitative methods. The empirical data is collected from 3 studies; longitudinal analyses of official register based data, a survey based on replication of official surveys and 74 interviews with long-term unemployed young adults. The statistical analyses state that there is a connection between early marginalisation and later marginalisation in this cohort. &lt;br/&gt;&lt;br&gt; The analyses of the interviews indicated three central themes which the respondents perceived as the most problematic issues in relation to being long-term unemployed and a social assistance recipient. Those were troubled economical circumstances, shame and lacking social recognition due to receiving social assistance and feelings of powerlessness in relation to the social services. The analyses in this dissertation shows that young adults that have had severe labour market difficulties during their establishment phase often experience multiple deprivation and more problematic living conditions compared with the normal population of the same age. They often have a marginalized or excluded position on several welfare dimensions. It is also evident that many experience cultural and institutional exclusion.The young adults often have several obstacles that hindered them from finding employment and a source of income. A recurring empirical pattern is that the respondents have many different problems at the same time. This accumulation of different problems often contribute to feelings of powerlessness in trying to solve the extensive and simultaneous difficulties. A central understanding of this situation is that the respondents often lack the resources that could enhance their possibilities to employment. Powerlessness is experienced in relation to concrete hindrances but also in emotional and relational experiences. This can be described as a double powerlessness.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Vid 1990-talets början drabbades Sverige av en omfattande lågkonjunktur. De unga som då skulle etableras på arbetsmarknaden var födda kring 1970-talets mitt. De fick erfara arbetslöshet och socialbidragstagande i avsevärt högre omfattning än någon tidigare generation i den moderna svenska välfärdsstaten. Trots ett förbättrat arbetsmarknadsläge fanns en grupp unga vuxna som varken fann anställning eller en väg till studier och självförsörjning. Denna avhandling syftar till att belysa både faktiska levnadsförhållanden samt hur arbetslöshet och socialbidragstagande upplevdes av denna grupp med långvariga arbetsmarknads- och försörjningsproblem. Avhandlingen baseras på både kvantitativ och kvalitativ metod och består av tre delstudier, longitudinella registeranalyser, en enkätstudie med replikering av offentliga surveystudier samt 74 intervjuer med unga vuxna som även 10 år efter 1990-talskrisen kvarstod i arbetslöshet och försörjningsproblem. De statistiska analyserna visar att det finns ett samband mellan tidig marginalisering och senare marginalisering i denna åldersgrupp. Analyserna av intervjuerna indikerar att det är tre centrala teman som dessa unga vuxna upplever som mest problematiska i relation till att vara arbetslös och socialbidragstagare. Dessa utgörs av en problematisk ekonomisk situation, upplevelser av skam och stigmatisering relaterat till socialbidragstagande samt erfarenheter av maktlöshet gentemot socialtjänsten. De unga med långvariga arbetsmarknadsproblem under etableringsfasen i vuxenliv har ofta en ansamling av ett flertal välfärdsproblem och mer problematiska levnadsförhållanden i jämförelse mot den jämnåriga normalpopulationen. Dessa unga vuxna har också ofta många olika problem i livssituationen samtidigt vilket kan utgöra ett hinder i försöken att etableras på arbetsmarknaden. Ett återkommande empiriskt mönster var att denna ackumulering av välfärdsproblem ofta bidrog till upplevelser av vanmakt inför bristande möjligheter och resurser att lösa de problem som utgjorde hinder på arbetsmarknaden. Dessa barriärer utgjordes av faktiska konkreta hinder men även emotionella och relationella upplevelser av vanmakt.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4483d584-a572-487a-8182-6696ec864bf2</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Angelinavhandling.pdf">https://portal.research.lu.se/files/3374520/1504325.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">904867</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>School of Social Work, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Ungdomsarbetslöshet</topic> <topic>försörjningsstöd</topic> <topic>socialbidrag</topic> <topic>vanmakt</topic> <topic>stigmatisering</topic> <topic>fattigdom</topic> <topic>aktivering</topic> </subject> <subject authority="lup"> <topic>Social Work</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Dissertations in Social Work</title> </titleInfo> <identifier type="issn">1650-3872</identifier> <identifier type="oldLupId">1504320</identifier> <part> <detail type="volume"> <number>38</number> </detail> <extent unit="pages"> <total>306</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-12-11T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>4483d584-a572-487a-8182-6696ec864bf2</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:35+02:00</recordDateApproved> </recordInfo> </mods>

This can be achieved by identification of prognostic and treatment predictive biomarkers, and by understanding the mechanisms behind early changes in the breast.&lt;br/&gt;&lt;br&gt; The cell cycle is a closely controlled process, involving multiple components with regulation on several levels. Loss of adequate cell proliferation control and cell cycle regulation is one of the main characteristic of cancer. In this thesis we have found that low level of the cell cycle regulatory protein p27 was associated with impaired&lt;br/&gt;&lt;br&gt; response to tamoxifen in premenopausal breast cancer patients, but not with prognosis. We have also observed that the expression of the microRNA (miRNA) miR-92a could provide independent prognostic information in breast cancer patients, and loss of miR-92a was associated with more severe breast cancer traits.&lt;br/&gt;&lt;br&gt; The earliest histologically identifiable breast lesion with an increased risk for developing breast cancer is called columnar cell hyperplasia (CCH). We have identified miRNA expression changes in CCH compared to normal mammary gland tissue in both epithelial cells and in the surrounding stroma. In addition we have linked epithelial expression of miR-27a, miR-92a andlet-7c to negative cell proliferation regulation, and stromal miR-I32 expression to alteration of genes associated with extra cellular matrix and actin-motility pathways in fibroblasts, and metabolic genes and pathways in co-cultured CCH epithelial cells.&lt;br/&gt;&lt;br&gt; Finally, cyclin Dl associated miR-483-5p affected cell migration in opposite directions depending on estrogen receptor status, highlighting the importance of subdivision of breast cancers in order to correctly understand the biology and subsequently for correct treatment of breast cancer subgroups.&lt;br/&gt;&lt;br&gt; In summary, these studies identified two potential biomarkers; one for predicting tamoxifen sensitivity, and one with prognostic value. We also revealed changes in miRNA expression in early premalignant breast lesions involved in cell proliferation, and opposing roles in cell migration for a cell cycle-related miRNA in breast cancer subgroup models.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Cancer är ett laddat ord, och för de flesta av oss är cancern inte längre bort än hos en nära släkting eller vän. Trots den gemensamma benämningen, är cancer är inte bara en sjukdom, utan ca 200 olika som alla har gemensamt att cellerna börjar dela sig okontrollerat. Cancer är väldigt vanligt och uppskattningsvis kommer var tredje person att drabbas av cancer under sin livstid. Bland män är prostatacancer vanligast och bland kvinnor är bröstcancer den vanligaste formen.&lt;br/&gt;&lt;br&gt; I Sverige är ungefär 30 % av alla cancerfall bland kvinnor bröstcancer, och cirka en av tio kvinnor riskerar att få diagnosen innan 75 års ålder. Antalet nya fall har ökat för vart år, och detta kan troligen kopplas till att fler blir upptäckta tack vare&lt;br/&gt;&lt;br&gt; mammografiundersökningar. Samtidigt har dödligheten stadigt sjunkit under de senaste åren, vilket vi förmodligen har nya och effektivare behandlingsmetoder att tacka för, samt att brösttumörerna upptäcks på ett tidigt stadium.&lt;br/&gt;&lt;br&gt; Förmågan för en normal cell att kunna dela sig är ytterst viktig, bl.a. vid sårläkning då nya celler måste bildas för att återställa huden. Denna delningsprocess kallas för cellcykel då cellen går igenom en cyklisk process där den återvänder till samma utgångspunkt som där den började, fast i två kopior. Cellcykeln är under sträng reglering och involverar många komponenter, både innanför och utanför cellerna. I normala fall när en delning ska ske, signalerar cellerna sinsemellan under väldigt kontrollerade former. En cancercell har däremot inte denna kontroll och kan dela sig utan att den får signaler. De cellulära proteinerna som driver cellcykeln kallas cykliner och CDK-proteiner. Dessa bildar komplex som får cellen att gå igenom cykeln och slutligen dela sig. I bröstcancerceller finns det ofta för mycket av den första cyklinen i cykeln, cyklin D1. För en kontrollerad celldelning krävs det att dessa komplex regleras och försvinner när de inte behövs längre. För det ändamålet finns proteiner som kallas&lt;br/&gt;&lt;br&gt; för CDK-inhibitorer, varav en heter p27. I cancerceller, som kännetecknas av att de har genetiska förändringar, sker ofta förändringarna i just proteiner och molekyler som är involverade i celldelning.&lt;br/&gt;&lt;br&gt; MikroRNA-gener är en relativt nyfunnen klass av gener som verkar genom att reglera uttrycket av specifika proteiner. Enkelt uttryckt kan man säga att om det är proteinerna som utför de olika arbetsuppgifterna i cellen, är det mikroRNA-generna som ser till så att det finns rätt mängd proteiner på rätt arbetsplats. Uppskattningsvis är cirka en tredjedel av alla 25 000 protein-kodande gener reglerade av olika&lt;br/&gt;&lt;br&gt; mikroRNA och det har visat sig att de är med i många olika processer i cellerna. Ett mikroRNA kan reglera flera proteiner och ett protein kan vara reglerat av flera mikroRNA, allt för att cellen ska vara så kontrollerad som möjligt för ett korrekt uppförande. Då mikroRNA-gener i stort sett kontrollerar alla viktiga processer i cellerna, är det inte förvånande att dessa gener är förändrade i cancerceller. Vi har&lt;br/&gt;&lt;br&gt; studerat mikroRNA-uttryck i förstadier till bröstcancer och funnit att redan där finns det skillnader. Vi har också undersökt ett specifikt mikroRNA i bröstcancertumörer och sett att minskade nivåer av det mikroRNAt är förknippat med sämre prognos. Vidare har vi sett att ett mikroRNA associerat med cellcykelproteinet cyklin D1 har olika roller i olika typer av bröstcancer vilket är en viktig observation för förståelse för uppförandet av olika bröstcancertyper.&lt;br/&gt;&lt;br&gt; Majoriteten av brösttumörer opereras bort genom att ta bort en del av bröstet eller i vissa fall hela bröstet. För att behöva ta bort så lite som möjligt kan patienter med avancerad bröstcancer få behandling innan operation, s.k. neoadjuvant behandling, som förhoppningsvis gör att tumören krymper. Denna förbehandling, t.ex. kemoterapi, kan också ge en indikation på huruvida tumörcellerna svarar på den typen av terapi och om den är effektiv för vidare behandling. Efter operation&lt;br/&gt;&lt;br&gt; behandlas patienten med strålning för att eliminera cancerceller som eventuellt blivit kvar. Patienten får också en efterbehandling, kallad adjuvant behandling, som kan bestå av kemoterapi eller anti-hormonell behandling. Den anti-hormonella behandlingen ges till patienter vars tumörer utrycker östrogenreceptorn. Det gör cirka 70 % av alla brösttumörer, och patienter med denna typ av tumör har oftast en bättre prognos. Östrogenreceptorn tillsammans med östrogen stimulerar cellen att dela sig. Genom att hämma antingen östrogenreceptorn eller produktionen av östrogen stoppas celldelningen. Det vanligaste preparatet för behandling av denna typ av brösttumörer heter tamoxifen och verkar genom att interagera med östrogenreceptorn, och därmed hindra östrogen från att få cellen att dela sig.&lt;br/&gt;&lt;br&gt; Precis som cancer är ett samlingsnamn på flera sjukdomar, är också bröstcancer uppdelad i ett flertal mindre subgrupper med olika karaktär. Dessa tumörgrupper kan skilja sig åt med avseende på hur prognosen för patienterna ser ut och huruvida en patient svarar på en viss behandling eller inte. För att kunna klassificera och hitta&lt;br/&gt;&lt;br&gt; dessa grupper behöver man mätbara biomarkörer, dvs. specifika komponenter i tumören som är annorlunda från normal frisk vävnad. Dessa molekylära komponenter i cellen är vanligtvis proteiner, men kan även vara RNA och DNA sekvenser. Östrogenreceptorn är ett bra exempel på en biomarkör som både kan ge information om patientens framtida sjukdomsbild, samt om tumören kommer att svara på anti-hormonell behandling, t.ex. tamoxifen. Trots detta finns det en del patienter med östrogenreceptor-positiva tumörer där tamoxifen inte har någon effect. För att kunna urskilja dem och direkt ge dem en annan effektiv behandling, är det viktigt att hitta ytterligare behandlingsprediktiva biomarkörer. I denna avhandling har vi identifierat att låga nivåer av det cellcykelreglerande proteinet p27, vars uttryck ofta är minskat i bröstcancertumörer, är associerat med sämre tamoxifensvar i östrogenreceptor-positiva tumörer, dvs. p27 är en behandlingsprediktiv biomarkör för tamoxifen. Däremot kunde vi inte se att p27 kunde förutse patientens sjukdomsförlopp.&lt;br/&gt;&lt;br&gt; Bröstet består av flera olika celltyper och kan grovt delas in i två avdelningar; den epiteliala och den stromala. I den epiteliala avdelningen finns det två celltyper, luminala epitelceller och basala myoepitelceller, och det är dessa två som utgör själva strukturen av det funktionella bröstet, dvs. står för produktionen av mjölk. Den&lt;br/&gt;&lt;br&gt; förgrenade strukturen i bröstet består av mjölkgångar. I ena änden mynnar dessa ut i bröstvårtan, och i andra änden finns en struktur som till formen är lik en klase med vindruvor. Denna vindruveklase är bröstets minsta funktionella del och kallas terminal duct lobular unit (TDLU) och består av en mjölkproducerande körtel och tillhörande mjölkgångar. Runt omkring finns den stromala avdelningen som&lt;br/&gt;&lt;br&gt; upprätthåller formen samt är väldigt viktig för hur cellerna i den epiteliala avdelningen beter sig. Bröstcancer börjar oftast i TDLU och i mjölkgångarna. Man tror att ett vanligt händelseförlopp för utvecklingen av bröstcancer går från förändringar i epitelcellerna i TDLU vidare till en ökad celldelning som till slut leder till att de tidigare normala epitelcellerna blir cancerceller som tar sig ut ur bröstet och sprider sig till andra organ och bildar dottertumörer, så kallade metastaser. Det är när cancern sprider sig som den utvecklas till en väldigt allvarlig sjukdom. Det är därför viktigt att hitta brösttumören innan den hinner komma till det stadiet. Det är också&lt;br/&gt;&lt;br&gt; viktigt att hitta tecken i förstadier till bröstcancer som tyder på att cellerna har en elakartad potential. Det kan man göra genom att titta på vilka gener som är förändrade. Den första strukturella förändringen i bröstet med ökad risk att utvecklas till bröstcancer kallas för columnarcellshyperplasi (CCH). Vi har identifierat förändringar i ett flertal mikroRNA-gener i CCH som kan ligga till grund för denna tidiga premaligna förändring i bröstet. Vi har även kopplat ihop några av dessa, bl.a. let-7c, med ökad celldelningsförmåga. Detta kan vara viktigt för att upptäcka tidiga&lt;br/&gt;&lt;br&gt; förändringar hos kvinnor som löper risk att utveckla bröstcancer.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis har studierna i denna avhandling identifierat cellcykelrelaterade biomarkörer för behandlingssvar av tamoxifen och prognostisk information, upptäckt celldelningsreglerande mikroRNA-gener i den tidigaste förändringen av bröstet med koppling till bröstcancer, samt visat hur ett cellcykelassocierat mikroRNA har olika&lt;br/&gt;&lt;br&gt; effekter i olika subgrupper av bröstcancer, och därmed påvisat vikten av att behandla bröstcancer utefter subgruppstillhörighet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/af30044d-9bdd-4098-afbd-eb42c8b8b26f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Sofie_Bjorner_kappa.pdf">https://portal.research.lu.se/files/3374680/3347893.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">8624197</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Pathology (Malmö)</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cancer and Oncology</topic> <topic>Cell and Molecular Biology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-74-6</identifier> <identifier type="oldLupId">3347864</identifier> <part> <detail type="volume"> <number>2013:6</number> </detail> <extent unit="pages"> <total>138</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-01-25T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>af30044d-9bdd-4098-afbd-eb42c8b8b26f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:37+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:37+02:00</recordDateApproved> </recordInfo> </mods>

So far, no evidence based management protocols are available adressing when to deliver these fetuses. The high risk of hypoxia and fetal death has to be balanced against that of extreme preterm birth with associated morbidity. The clinical routine in Lund has been a proactive management, that is to deliver on fetal indication before occurence of more severe hemodynamic changes. The aim of this study was to evaluate short and long-term consequences in very preterm IUGR fetuses (PT-IUGR) with abnormal blood flow in the umbilical artery.&lt;br/&gt;&lt;br&gt; Study I: Mortality and neonatal morbidity did not differ between the PT-IUGR group and the very preterm background population, born before 30 gestational weeks (GW) in 1998-2004, with the exception of chronic lung disease (p &amp;lt;0.01). Survival without major neurological handicap at two years was equal between the two groups.&lt;br/&gt;&lt;br&gt; Study II: At early school age, cognitive impairment was more prevalent in boys born very preterm with IUGR compared to a matched very preterm group with BW appropriate for gestational age (PT-AGA). Attention deficit&lt;br/&gt;&lt;br&gt; disorders were more prevalent in children in both preterm groups compared to term children with birth weight AGA (T-AGA) (p &amp;lt;0.01). There was a trend towards more behavioral problems in the preterm groups.&lt;br/&gt;&lt;br&gt; Study III: Lung function, assessed with spirometry in children at 6-10 years, was reduced in the PT-IUGR group compared to the T-AGA group. The PT-IUGR group had worse lung function when born after 26 GW in comparison to the PT-AGA group (p&amp;lt;0.05).&lt;br/&gt;&lt;br&gt; Study IV: Cardiovascular measurements were assessed at 5-8 years. Systolic and mean blood pressure, adjusted for height, was higher in both preterm groups compared to the T-AGA group (p&amp;lt;0.05). Findings in the vascular&lt;br/&gt;&lt;br&gt; measurements were different between the preterm groups; the PT-IUGR group had lower aortic stiffness (p&amp;lt;0.01) and lower endothelial-dependent vasodilation compared to the PT-AGA group (p&amp;lt;0.05), and thinner intima media&lt;br/&gt;&lt;br&gt; thickness in the carotid artery compared to the T-AGA group (p&amp;lt;0.05).&lt;br/&gt;&lt;br&gt; Conclusions: IUGR in very preterm birth did not have an impact on overall mortality or major handicaps. Impairment in lung function was only apparent in the preterm IUGR group after 26 GW, a period of gestation when delivery on&lt;br/&gt;&lt;br&gt; fetal indication in general is considered acceptable. The adverse impact of IUGR on cognitive function was present at all gestational ages, but cognitive impairment was only significant in IUGR boys compared to preterm controls. The&lt;br/&gt;&lt;br&gt; question whether the cognitive impairment in boys is transient or persistent remains unanswered. It is difficult to understand the implication of the outcomes of lower IMT and aortic stiffness seen in the preterm IUGR group on later cardiovascular health. Further studies have to be performed in older ages. The observed outcome would not seem to be sufficiently severe to refrain from delivery in these very preterm IUGR fetuses and we suggest that it is justified to deliver fetuses with IUGR and abnormal blood flow in the umbilical artery at early gestational age in order to prevent intrauterine death.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d207d0f6-4355-4a63-a02a-93a5158ffa76</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis__eva.morsing.pdf">https://portal.research.lu.se/files/3375297/2214166.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">447809</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Pediatrics, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>umbilical artery</topic> <topic>cognitive development</topic> <topic>lung function</topic> <topic>cardiovascular function</topic> <topic>very preterm infants</topic> <topic>Doppler ultrasound</topic> <topic>Intrauterine growth restriction</topic> </subject> <subject authority="lup"> <topic>Pediatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-55-0</identifier> <identifier type="oldLupId">2214161</identifier> <part> <detail type="volume"> <number>2011:105</number> </detail> <extent unit="pages"> <total>152</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-12-16T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>d207d0f6-4355-4a63-a02a-93a5158ffa76</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:43+02:00</recordDateApproved> </recordInfo> </mods>

In study I, observations of the performance of self-care and household occupations were pursued in 44 participants, and study II identified self-perceived problems in performance of occupations in 47 participants. In studies III and IV, in-depth interviews with ten participants revealed experiences related to engagement in occupations and to the process of adaptation of engagement in occupations. The results showed that persons with MS can perceive problems related to all areas of occupations, and at different hierarchical levels. They can be dissatisfied with performance in occupations, especially related to self-care and household occupations and observational assessments confirm that performance in these occupations is impacted on. Furthermore, they can be independent in self-care but dependent in household occupations, and can have problems in their performance regardless of their age, disease severity, or their living arrangements. They can experience that they need to struggle continuously to manage occupations, and that this changes them as a person and make them live their lives differently than they had anticipated. In addition, they experience their adaptation of engagement in occupations as an ongoing, non-linear process, involving both themselves and their family, and they consider who would benefit the most, before they choose their adaptation of engagement in occupations. In summary, this thesis has shown that engagement in occupations in persons with MS is a complex phenomenon. All areas of occupations can be affected, and need to be addressed within occupational therapy and rehabilitation. Clients’ own experiences needs to be elucidated in order to facilitate the reconstruction of self, identity and support the process of adaptation of occupations.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3d71bf5d-a449-4c2d-8eb8-bc288b8fbfb4</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Inlaga-Mansson-Lexell.pdf">https://portal.research.lu.se/files/3375572/1304268.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1701764</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>social environment</topic> <topic>adaptation</topic> <topic>identity</topic> <topic>self</topic> <topic>ADL</topic> <topic>rehabilitation</topic> <topic>occupational therapy</topic> <topic>engagement in occupations</topic> <topic>Multiple Sclerosis</topic> </subject> <subject authority="lup"> <topic>Occupational Therapy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-13-4</identifier> <identifier type="oldLupId">1303292</identifier> <part> <detail type="volume"> <number>2009:26</number> </detail> <extent unit="pages"> <total>128</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-03-27T09:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

In addition the level of physical activity decreases with increasing age. For persons aging with a disability it may be a challenge to engage in physical activity, partly because of the disability and partly because of contextual barriers. One group of persons aging with a disability is those with late effects of polio. The latter are recommended being physically active with respect to their impairments and activity limitations but there is very limited knowledge regarding their engagement in physical activity and related factors.&lt;br/&gt;&lt;br&gt; The overall aim of this thesis was to increase knowledge about PA in ambulatory persons with late effects of polio by describing PA, assessing the relationships between PA and impairments, activity limitations, participation restrictions and life satisfaction, and furthermore by exploring perceptions of PA. The 81 participants had a confirmed history of acute poliomyelitis affecting the lower limbs, and were between 50 and 80 years of age. In the first study physical activity was analysed by self-report (The Physical Activity and Disability Survey) and by a pedometer. In the second and third study impairments, activity limitations and participation restrictions common in this population were assessed. The fourth study was qualitative and 15 participants were individually interviewed regarding their perception of physical activity and the personal and environmental factors related to physical activity. The results showed that the participants were physically active on average three hours per day, mostly in low-level intensity activities and walked on average 6212 steps per day. The amount of PA varied considerably between the participants. There was a positive association between physical activity and life satisfaction. Physical activity was associated with impairments (knee muscle strength and self-reported impairments), activity limitations and participation restrictions (gait performance, self-reported limitations in walking and fear of falling). The variance in physical activity was moderately explained by the assessed impairments, activity limitations and participation restrictions. Overall the participants had a positive perception of physical activity but multiple factors affected them in their effort to perform PA. The participants described aspects that were closely related to the late effects of polio, such as specific impairments, changes in physical activity over time, past experiences, and contextual barriers. Persons with late effects of polio want to be physically active but may need assistance in order to be able to create suitable strategies for minimizing the impact of their impairments, to prioritize and to change aspects of performance. These results could assist health care professionals in guiding this group to achieve or maintain an active and healthy lifestyle.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/4ebbde5e-9ad0-4678-9e80-8bc4e32360a0</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_CW1411.pdf">https://portal.research.lu.se/files/3375958/4814067.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">815310</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Rehabilitation medicine, Department of Health Sciences</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>exercise</topic> <topic>gait</topic> <topic>the International Classification of Functioning</topic> <topic>Disability and Health (ICF)</topic> <topic>lifestyle</topic> <topic>muscle strength</topic> <topic>Post poliomyelitis syndrome</topic> <topic>qualitative research</topic> <topic>rehabilitation</topic> <topic>self-report</topic> <topic>walking</topic> </subject> <subject authority="lup"> <topic>Other Medical and Health Sciences not elsewhere specified</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-076-0</identifier> <identifier type="oldLupId">4814065</identifier> <part> <detail type="volume"> <number>2014:147</number> </detail> <extent unit="pages"> <total>67</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://www.sciencedirect.com/science/article/pii/S1936657414000089</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://www.sciencedirect.com/science/article/pii/S1934148214013677</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://journals.humankinetics.com/japa-in-press/japa-in-press/physical-activity-and-the-association-with-self-reported-impairments-walking-limitations-fear-of-falling-and-incidence-of-falls-in-persons-with-late-effects-of-polio</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-12-18T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>4ebbde5e-9ad0-4678-9e80-8bc4e32360a0</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:26:57+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:26:57+02:00</recordDateApproved> </recordInfo> </mods>

The pathophysiological alterations resulting in proteinuria are obscure, although proteinuria is&lt;br/&gt;&lt;br&gt; often associated with pathological changes in the glomerular filtration barrier (GFB). It is therefore of great interest to&lt;br/&gt;&lt;br&gt; study the physiology of the GFB, in order to be able to prevent or reduce proteinuria.&lt;br/&gt;&lt;br&gt; The studies in this thesis were performed using an in vivo model in anesthetized rats. The rats were cannulated for blood&lt;br/&gt;&lt;br&gt; access and the left ureter cannulated for urine collection through a small abdominal incision. The glomerular permeability&lt;br/&gt;&lt;br&gt; was measured using sieving coefficients (θ) for fluorescently labeled Ficoll (FITC-Ficoll) with a molecular radius ranging&lt;br/&gt;&lt;br&gt; from 10Å to 80Å. The rats were infused with FITC-Ficoll, and blood- and urine samples were collected and analyzed&lt;br/&gt;&lt;br&gt; with high performance size exclusion chromatography (HPSEC).&lt;br/&gt;&lt;br&gt; In study I, the GFB charge-selectivity was explored using a negatively charged, conformationally intact anionic Ficoll&lt;br/&gt;&lt;br&gt; (CMI-Ficoll), comparing it to neutral Ficoll, of same Stokes-Einstein (SE) radius. The sieving of CMI-Ficoll was reduced&lt;br/&gt;&lt;br&gt; across the GFB compared to neutral Ficoll for molecules of radius 20-35Å. The GFB was thus found to be negatively&lt;br/&gt;&lt;br&gt; charged. However, the charge was of much less magnitude than previously estimated.&lt;br/&gt;&lt;br&gt; In study II, the proposed effects of systemic infusion of protamine sulfate (PS) and hyaluronidase (Hyase) on the GFB&lt;br/&gt;&lt;br&gt; charge-selectivity were studied. PS and to some extent Hyase, increased the permeability for Ficoll molecules &amp;gt; 50Å, but&lt;br/&gt;&lt;br&gt; had no effect on the charge-selectivity of the GFB.&lt;br/&gt;&lt;br&gt; In study III, the permeability effects of extracellular adult (HbA) and fetal hemoglobin (HbF) were studied, showing&lt;br/&gt;&lt;br&gt; increases in θ for macromolecules (50-80Å in radius) after infusion of HbF, but not after HbA or cyano-inactivated HbF&lt;br/&gt;&lt;br&gt; (CN-HbF) infusions. Tempol (a superoxide radical scavenger) and α-1-microglobulin (A1M; a physiological hemebinding&lt;br/&gt;&lt;br&gt; protein and radical scavenger), both prevented the increase in the permeability of the GFB.&lt;br/&gt;&lt;br&gt; In study IV, the effects of the pro-inflammatory cytokines, TNF-α, Il-1β and IL-6, on the GFB permeability were&lt;br/&gt;&lt;br&gt; studied. TNF-α and Il-1β caused a rapid, reversible, increase in glomerular permeability, while IL-6 generated a more&lt;br/&gt;&lt;br&gt; gradual response. These effects could be inhibited with tempol, showing a reactive oxygen species (ROS) dependency of&lt;br/&gt;&lt;br&gt; the cytokine effects on the GFB permeability.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7c46b18a-3152-4940-9bdb-edd088b6dd6a</url> </location> </relatedItem> <originInfo> <publisher>Njurmedicin, Institutionen för Kliniska Vetenskaper Lund</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-129-3</identifier> <identifier type="oldLupId">5323090</identifier> <part> <detail type="volume"> <number>2015:50</number> </detail> <extent unit="pages"> <total>84</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-20T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>7c46b18a-3152-4940-9bdb-edd088b6dd6a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:27:15+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:27:15+02:00</recordDateApproved> </recordInfo> </mods>

The host reaction, however, to both trauma and infection involves a strong inflammatory response, with the classical symptomology of rubor, tumor, calor, dolor et functio laesa. Tumor, swelling, will increase the volume within the closed cranial vault, and may thereby raise the intracranial pressure to critical levels, affecting cerebral blood flow and oxygenation. In this thesis, brain oedema and its origins are investigated in experimental models of brain trauma and bacterial meningitis, and in patients suffering severe head injury. The studies are focused on fluid therapy, blood-brain barrier permeability changes, and their effects on oedema formation.&lt;br/&gt;&lt;br&gt; In study I and II, it was shown that plasma volume expansion with crystalloid compared to colloid fluids resulted in increased cortical brain oedema after brain trauma in rats, and increased intracranial pressure in experimental meningitis in cats. Evidence is given that increased permeability of the blood-brain barrier is a key determinant of tissue water content after the insults.&lt;br/&gt;&lt;br&gt; In study III, it was shown that post treatment with prostacyclin in experimental meningitis reduces systemic plasma volume loss, and may diminish the rise in intracranial pressure.&lt;br/&gt;&lt;br&gt; In study IV, the effect of statin treatment after brain trauma in rats was investigated. No effect on brain oedema, cortical blood flow, or the transfer constant for a small molecule was detected, but capillary patency was better preserved in the statin group. Statin treatment was associated with increased plasma levels of nitric oxide, and decreased levels of prostacyclin. &lt;br/&gt;&lt;br&gt; In study V, post-traumatic permeability changes of the blood-brain barrier in 17 brain trauma patients were quantified using contrast enhanced computerized tomography with multiple scanning during 25 minutes. It was shown that blood to brain transfer for iohexol was increased up to 20-fold in traumatized tissue. The relevance of these results regarding our understanding of the pathophysiology of post-traumatic brain oedema, and the implications for the clinical management of brain trauma patients are discussed.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/887f5544-ee31-46f4-a840-9c17c5a6632d</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="MJ.pdf">https://portal.research.lu.se/files/3382860/3412795.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1565560</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>traumatic brain injury</topic> <topic>brain oedema</topic> <topic>fluid therapy</topic> <topic>blood-brain barrier</topic> </subject> <subject authority="lup"> <topic>Anesthesiology and Intensive Care</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-81-9</identifier> <identifier type="oldLupId">3131999</identifier> <part> <detail type="volume"> <number>2012:19</number> </detail> <extent unit="pages"> <total>127</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-03-09T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>887f5544-ee31-46f4-a840-9c17c5a6632d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:27:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-28T11:37:09Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:27:24+02:00</recordDateApproved> </recordInfo> </mods>

This leakage increases rapidly in prostate disease, and PSA is used worldwide as a marker of prostate cancer. PSA is activated in vitro by hK2, and cleaves the semenogelins in semen, which releases motile sperm, and low levels of PSA have been associated with low sperm motility. &lt;br/&gt;&lt;br&gt; The present objective was to evaluate factors that might influence release of hK2 and PSA, and to study those two proteins with regard to their levels in seminal plasma and blood, and their association with sperm motility in young healthy men without prostate disease.&lt;br/&gt;&lt;br&gt; PSA and hK2 were measured by immunofluorometric assay. Genomic DNA was prepared from peripheral leukocytes, and genotyping was performed with the Sequenom Mass Array System. Levels of hK2 and PSA were found to be associated with variants in the genes encoding hK2 (KLK2) and PSA (KLK3) in young men (mean age 18 years). The single-nucleotide polymorphisms (SNPs) rs198972, rs198977, rs198978, and “SNP2” in KLK2 were associated with lower hK2 levels in seminal plasma and serum in carriers of the TT genotype. In KLK3, the AA genotype in rs266882 in combination with CAG &amp;gt; 22 were correlated with higher total PSA (tPSA) in serum; rs2271094 and “SNP1&quot; were associated with lower tPSA concentrations in seminal plasma from subjects homozygous for the common allele (A or G, respectively). Carriers of the common T allele in rs1058205 in KLK3, had higher amounts of tPSA in seminal plasma, higher concentrations of tPSA in serum, and a lower ratio of free to tPSA (%fPSA). Free PSA (fPSA) in blood showed ~17% co-variation with PSA in semen, whereas no relationship was found between levels of complexed PSA (cPSA) in blood and PSA in semen. In blood, levels of cPSA, but not fPSA, increased with age, which may reflect an increasing incidence of prostate disease. In men 19–40 years, an age when reproduction most commonly takes place, correlations were found between hK2 and PSA in seminal plasma (p &amp;lt; 0.001, r = 0.47) and between hK2 and age (p = 0.01, r = –0.20). Men in that age group who were in the lowest quartile with respect to amount of PSA in seminal plasma, semen volume, and zinc concentration had, respectively, 5.8%, 4.1%, and 3.9% fewer progressively motile sperm. These findings suggest that a decrease in secretory function of the prostate can impair sperm motility. The present results obtained by analysing the allelic variants of KLK2 and KLK3 might be useful for refining models of PSA cut-off values in PCa testing.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/ffcb424d-1099-4cba-a7d7-668b8f32039f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="charlotta_kappa.pdf">https://portal.research.lu.se/files/3382962/1149897.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4317570</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>human glandular kallikrein 2</topic> <topic>KLK3</topic> <topic>hk2</topic> <topic>prostate-specific antigen</topic> <topic>PSA</topic> <topic>sperm motility</topic> <topic>seminal plasma</topic> <topic>androgen receptor</topic> <topic>SNP</topic> <topic>CAG</topic> <topic>KLK2</topic> </subject> <subject authority="lup"> <topic>Medicinal Chemistry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-00-2</identifier> <identifier type="oldLupId">1059441</identifier> <part> <detail type="volume"> <number>2008:47</number> </detail> <extent unit="pages"> <total>124</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-10T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>ffcb424d-1099-4cba-a7d7-668b8f32039f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:27:26+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:27:26+02:00</recordDateApproved> </recordInfo> </mods>

Environmental risk factors are of potential interest for both prevention and treatment of RA. &lt;br/&gt;&lt;br&gt; Our aim was to examine changes in the occurrence of CVD over time and, using immunohistochemistry, study markers of inflammation in vascular endothelial cells during treatment with a TNF-inhibitor. We also investigated predictors of RA.&lt;br/&gt;&lt;br&gt; Two community based of RA cohorts were established in 1978 and 1995 and compared to the corresponding background population regarding CVD. Patients were followed for 8 years, and fatal and non-fatal cardiovascular first events were identified.&lt;br/&gt;&lt;br&gt; To investigate markers of endothelial activation, we used fourteen patients with active RA who started anti-TNF treatment. Muscle biopsies were taken at baseline and 3 months after start of treatment.&lt;br/&gt;&lt;br&gt; To identify incident cases of RA for evaluation of predictors of RA, we used two large surveys, the Malmö Preventive Medicine Program and the Malmö Diet Cancer Study. &lt;br/&gt;&lt;br&gt; Cardiovascular morbidity and mortality in the two community based RA cohorts was increased compared to the background population. Treatment with adalimumab was associated with decreased expression of endothelial markers previously associated with severe systemic inflammation in RA. &lt;br/&gt;&lt;br&gt; Smoking and a low level of formal education were independent risk factors for RA. Moderate alcohol consumption was associated with a reduced risk of RA. Reduced pulmonary function was not associated with future RA, but smoking and low socioeconomic status were independent predictors of RA.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/bc300e77-9492-4dca-84fb-a3c25435105b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="avhandling__ulf_bergstrom2.pdf">https://portal.research.lu.se/files/3382985/1977698.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7628111</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Unit of Rheumatology, Dept of Clinical Sciences, Malmö.</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Rheumatoid arthritis</topic> <topic>Cardiovascular disease and Risk factors</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-90-7</identifier> <identifier type="oldLupId">1894489</identifier> <part> <detail type="volume"> <number>2011:42</number> </detail> <extent unit="pages"> <total>122</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-05-19T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>bc300e77-9492-4dca-84fb-a3c25435105b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:27:27+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:27:27+02:00</recordDateApproved> </recordInfo> </mods>

Initially, an overview of the history and current status of the language of Älvdalen is given, and the focus of the dissertation is on certain syntactic phenomena that have been well studied from a comparative and diachronic perspective in other Scandinavian languages but not in Övdalian. The examined variant of Övdalian is the one spoken by people born between the 1920’s and the 1940’s and it is called Traditional Övdalian. The empirical data were collected by means on elicitation of grammaticality judgements from twelve native speakers of Traditional Övdalian. These new data are analysed within a general Principal and Parameters approach and the point of departure is the framework of Holmberg &amp;amp; Platzack (1995) who argue that a number of word order phenomena depend on two morphological parameters: subject-verb agreement and morphological case. Övdalian word order is also compared with the word order of the other Scandinavian languages and an underlying syntactic structure of Övdalian is proposed. The main focus of the dissertation lies on two phenomena that have often been connected to verbal morphology, that is V-to-I movement and Stylistic Fronting, which were both present in Övdalian at the beginning of the 20th century. It is shown that V-to-I movement has become optional in Övdalian during the last hundred years in absence of any change in the verbal morphology, and the ongoing loss of V-to-I movement is argued to be triggered by a high, pre-subject negation (and sentential adverbial) placement. This placement gives no clue to the speakers as to whether the finite verb is raised to I or not. Stylistic Fronting is lost in Traditional Övdalian and it is maintained that this loss is connected to the changed status of the landing site of Stylistic Fronting, that is Spec,TP. While Spec,TP was a position accessible to many syntactical constituents in older Övdalian, it has later become a position to which only the subject may move. This explains the loss of SF in the absence of changes in the verbal morphology.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5e60a1c3-0d6d-4ca6-92b9-18ff955a7ae6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Piotr_Garbacz_2010_-_Word_Order_in_Ovdalian.pdf">https://portal.research.lu.se/files/3383250/1567413.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4562274</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Centre for Languages and Literature, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Stylistic Fronting</topic> <topic>V-to-I movement</topic> <topic>Swedish dialects</topic> <topic>dialect syntax</topic> <topic>language change</topic> <topic>variation</topic> <topic>älvdalsmålet</topic> <topic>Övdalian</topic> <topic>Elfdalian</topic> <topic>the Rich Agreement Hypothesis</topic> <topic>negative concord</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lundastudier i nordisk språkvetenskap.

His reputation is due to the worldwide success of his novels, especially Texaco, winner of the Prix Goncourt-award in 1992, but also to the fact that he is the leading theorist of the Créolité, an ideological movement whose aim is to preserve the character of Creole identity and culture against the threat of assimilation. Chamoiseau’s importance in an ideological context tends to overshadow his literary qualities, his novels being often seen as illustrations of his political ideas.&lt;br/&gt;&lt;br&gt; Although Chamoiseau’s ideological views aren’t totally absent from his literary work, his novels strike the reader as extremely complex constructions, containing far more than a subversive aspect. An aspect that has been neglected by the critics is for example the supernatural. Probably because of the geographic vicinity to South America, Chamoiseau’s use of the supernatural has been, rather hastily, considered as typical of magical realism or marvellous realism. This dissertation aims at showing that the fantastic, as defined by Tzvetan Todorov (1970), is better suited to describe this aspect of Chamoiseau’s novels, especially Biblique des derniers gestes (2002).&lt;br/&gt;&lt;br&gt; Our main objective is, however, not to decide whether the novel belongs to the fantastic as a genre, but to examine the reasons why it is used. A close analysis shows that it is often in relation to the past of Martinique that the supernatural appears. Thanks to the theory of the fantastic, we find three possible explanations of this fact. Firstly, the supernatural is juxtaposed to the real in order to reveal its limits and its “constructedness”. Martinican past thus appears as a French construction. Secondly, the fantastic can be used to reveal the absence of genuine Martinican history. Finally, the fantastic can be a reminder of a terrible event from the past. In conclusion it can be said that Chamoiseau uses the fantastic in order to write the history of an event that he sees as the origin of Martinique: slavery. By doing this he contributes to the fantastic as well, by showing that it is not necessarily gratuitous and by providing a good example of original and innovative use.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/64425bef-361e-4874-993e-c36556f68237</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Liviu_Lutas_THESIS_sur_Bibliques_des_derniers_gestes_-_fantastique_et_Histoire.pdf">https://portal.research.lu.se/files/3383293/1144808.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1623070</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Språk- och litteraturcentrum, Lunds universitet</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">fre</languageTerm> </language> <subject> <topic>métalepse</topic> <topic>Post-colonialisme</topic> <topic>Surnaturel</topic> <topic>Réalisme magique</topic> <topic>Histoire</topic> <topic>Réalisme merveilleux</topic> <topic>Fantastique</topic> <topic>the uncanny</topic> <topic>l&apos;inquiétante étrangeté</topic> <topic>Chamoiseau</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Études Romanes de Lund</title> </titleInfo> <identifier type="issn">0347-0822</identifier> <identifier type="isbn">978-91-628-7472-8</identifier> <identifier type="oldLupId">1067419</identifier> <part> <detail type="volume"> <number>82</number> </detail> <extent unit="pages"> <total>235</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-23T14:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>64425bef-361e-4874-993e-c36556f68237</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:27:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:27:31+02:00</recordDateApproved> </recordInfo> </mods>

Its target enzymes are thought to be the lysosomal cysteine cathepsins and legumain. Cystatin C has been considered to excert its enzyme inhibiting functions extracellularly, as a defense against enzymes from leaking lysosomes or invading pathogens. &lt;br/&gt;&lt;br&gt; It was demonstrated by various techniques, including flow cytometry, confocal microscopy, ELISA and Western blotting, that cystatin C was internalised in cells of different cell lines after incubation with a physiological concentration of cystatin C. The internalised cystatin C was found in acidic endolysosomal vesicles and co-located with some potential target enzymes, in contrast to the endogenously produced inhibitor, which was mainly found in the endoplasmic reticulum. Cystatin C was non-degraded and still functional as an inhibitor of cysteine cathepsins after uptake, as the total enzyme inhibiting capacity of the cell lysates was increased, suggesting that intracellular cysteine protease activity can be regulated by the uptake. Invasion and migration of MCF-7 breast cancer cells were inhibited when cells were incubated in medium containing cystatin C. &lt;br/&gt;&lt;br&gt; To pin-point the structural requirements for cellular uptake, twelve variants of cystatin C, including wild-type, were produced by site-directed mutagenesis and cleaving of the N-terminal. Positively charged amino acid residues on the surface of the molecule, and the amino acid at position 106 were shown to be important for internalisation. In most cases the uptake was decreased after molecular engineering, but for the variant W106F-cystatin C it was increased. The substitution of W106 affects the cathepsin-inhibiting properties of cystatin C, but it is still an efficient inhibitor of legumain. The increased uptake of this variant also induced an increased inhibition of legumain in lysates of cells after uptake.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; The secreted cysteine protease inhibitor cystatin C has been thought to exert its functions extracellularly, as a defense against enzymes from leaking lysosomes or invading pathogens. In this thesis we demonstrate that regulation of intracellular proteases by cystatin C is possible, as a result of cellular uptake, and that the uptake can be modulated by molecular engineering of wild-type cystatin C. The uptake was seen in different epithelial and neuroblastoma cancer cell lines and was shown by various techniques, including flow cytometry, confocal microscopy, ELISA and Western blotting. Intracellular cysteine proteases involved in cancer-promoting processes may thus be controlled by cystatin C uptake.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9baf9542-ca69-496f-8a4b-f2f1e49c8ea5</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_130807_hw.pdf">https://portal.research.lu.se/files/3387001/3992325.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2974907</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Clinical Chemistry and Pharmacology, Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cathepsin</topic> <topic>cell line</topic> <topic>co-localisation</topic> <topic>cystatin C</topic> <topic>internalisation</topic> <topic>legumain</topic> </subject> <subject authority="lup"> <topic>Pharmacology and Toxicology</topic> <topic>Medicinal Chemistry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-57-4</identifier> <identifier type="oldLupId">3991196</identifier> <part> <detail type="volume"> <number>2013:85</number> </detail> <extent unit="pages"> <total>58</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-09-13T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>9baf9542-ca69-496f-8a4b-f2f1e49c8ea5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:27:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:27:40+02:00</recordDateApproved> </recordInfo> </mods>

Tube formation involves a series of dynamic and interdependent cellular processes, including cytoskeletal reorganization, assembly of intercellular junctional complexes, and cell polarization. Understanding how cells polarize and coordinate tubulogenesis during organ formation is a central question in biology. Tubulogenesis often coincides with cell lineage specification during organ development. Hence, an elementary question is whether these two processes are independently controlled, or whether proper cell specification depends on formation of tubes. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To address these fundamental questions, we have studied the functional role of Cdc42 in pancreatic tubulogenesis. We present evidence that Cdc42 is essential for tube formation, specifically for initiating microlumen formation and later for maintaining apical cell polarity. Finally, we show that Cdc42 controls cell specification non-cell-autonomously by providing the correct microenvironment for proper control of cell fate choices of multipotent progenitors.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; To understand the process and importance of endocrine cell delamination and migration from the ductal epithelium, we used transgenic mouse models expressing the dominant active Cdc42 (Cdc42 DA) or the dominant negative Rac1 (Rac1 DN) in the insulin cells. Active Cdc42 enhanced E-cadherin and F-actin at the cell-cell contacts and blocked the delamination of newly formed insulin cells. The beta cell numbers were severely reduced and resulted in hyperglycemia. Expression of dominant negative Rac1 did not affect the delamination but impaired the subsequent migration and organization of islet cells. E-cadherin was enhanced in the cell-cell contacts of the transgenic islet cells expressing Rac1 DN.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Our results describe the process of tube formation in glandular organs like pancreas and identified key regulators in the process. In addition, we show tube formation plays a crucial role in establishing correct microenvironment for proper cell fate specification.

By means of constraint, it focuses on Ambroise Paré (1509/10–90) and Gilles Deleuze (1925–95) as representatives of early humanism and posthumanism, respectively. The study is divided into four chronologically ordered parts. In part I, four teratological traditions of philosophical import are discerned in antiquity: the naturalist, the humanist, the metaphysical, and the hermeneutical (each associated with a set of key names: in particular, Empedocles, Lucretius; Socrates, Protagoras; Plato, Aristotle; and Pliny, Augustine). Part II follows these traditions into the Renaissance where they intersect in the ‘books of wonder’, among which Paré’s Des monstres et prodiges (1573) is viewed to have had a lasting influence on the development of the science of teratology. Criticizing the positivistic conventions of interpretation of the book in question, notions of order, causality, diversity, and novelty are analyzed for the purpose of excavating from Paré’s work a natural philosophy which hinges on man’s capacity for knowledge; in such a humanist conception, monsters are not so much naturalized as nature becomes monstrous, while man is taken to reflect and encompass all the properties of natural things, thereby incorporating monstrosity in his singular variability. Part III provides an overview of the development of a scientific teratology from Cartesian mechanicism and rationalism, through theories of preformation, epigenesis, and transformation, to the materialist and vitalist debates of the early nineteenth century, when Étienne and Isidore Geoffroy Saint-Hilaire create the discipline of teratology, and its aftermath in developmental and evolutionary biology. The general theme is the place of anomalies in the normal scheme of nature (and culture), as man becomes progressively taken as the norm for thought, ultimately rendering the inhuman as such unthought. Finally, part IV looks to Deleuze as an attempt in the late 1900s to construct a posthumanist philosophy of nature where monstrosity is the problem which rather generates thought; it thus chronologically traces formulations of a concept of monstrosity in his body of work, from the 1940s to the 1990s. In Différence et répétition (1968), Deleuze is found to furnish three interconnected theses to define monstrosity, regarding problems of determination, synthesis, and differentiation, where the problematic as such (the nature of difference itself) is conceptualized as the ‘idea’ of monstrosity, not any particular physical shape. After analyzing the concept of the ‘body without organs’ as an issue of identity and materiality, tracing it back to its formulation in Logique du sens (1969), these theses of monstrosity are then applied to a study of Deleuze’s later philosophy, emphasizing Mille plateaux (1980), Logique de la sensation (1981), and Cinéma 1–2 (1983–85), as side-stepping the human norm in order to think its anomaly (the inhuman) as the condition for creativity. This is evidenced in his ideas of technology and the arts as experimental practices of becoming inhuman. The monster is thus regarded as a ‘conceptual persona’ in a Deleuzian philosophy of the virtual Figure—challenging all actual forms—of an inhuman time for the experience of difference in itself.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Avhandlingens ämne är monstrets roll i människans försök att definiera sig själv – hur kroppar som kan benämnas ”monstruösa” fungerar som naturfilosofiska figurer i humanismens strävan att avgränsa det mänskliga från det omänskliga. Studien spänner över perioden från renässansen eller den tidigmoderna eran till postmoderniteten men fokuserar den franska miljön och två gestalter som representerar skiftet från den tidiga humanismen till posthumanismen: å ena sidan Ambroise Paré (1509–1590), känd som ”den moderna kirurgins fader”, och å andra sidan Gilles Deleuze (1925-1995), en av efterkrigstidens mest betydande filosofer. Inriktningen i denna studie är därför på ett möte mellan naturvetenskap och filosofi i ett ämne som tenderar att stötas ut från dem båda: det monstruösa. Här framhävs i stället monstruositet som ett begrepp med vittomfattande och djupa implikationer för förståelsen av vad som accepteras som mänskligt, naturligt och värdigt liv. Den historiska studien visar dels hur denna problematik löper genom idéhistorien, från antiken in i vår samtid, med ständigt förnyad aktualitet (från mytologi och spådomskonst till cybernetik och genteknik, via naturalhistoria och utvecklingslära), dels hur monstret självt på många sätt trängts undan i ett slags utrotningshistoria i etableringen av ”det normala”, som är humanismens kanske mest centrala problem: risken att finna det omänskliga i människan.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9f9b9a2e-54c5-4b70-9490-7633fddc6d6b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Monstret &amp; människan.pdf">https://portal.research.lu.se/files/169122847/Monstret_ma_nniskan.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5836411</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Sekel Bokförlag</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>materiality</topic> <topic>difference</topic> <topic>the body</topic> <topic>teratology</topic> <topic>humanist philosophy</topic> <topic>monstrosity</topic> <topic>anomaly</topic> <topic>the inhuman</topic> <topic>Ambroise Paré</topic> <topic>Gilles Deleuze</topic> <topic>natural philosophy</topic> <topic>Geoffroy Saint-Hilaire</topic> <topic>organization</topic> <topic>the posthuman</topic> <topic>order</topic> <topic>affect</topic> <topic>multiplicity</topic> <topic>becoming</topic> </subject> <subject authority="lup"> <topic>Cultural Studies</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Ugglan.

The empirical basis of the study consists of interviews with 58 students taking one of three courses at Halmstad University. Despite considerable efforts being made in the twentieth century, socially uneven recruitment to higher education remained largely unaltered between the 1960s and the 1990s. During the 1990s there was some evening out, but in 1999 it was still the case that only 24 per cent of university and college students came from working-class homes, which at that point made up 35 per cent of the population as a whole. Students with highly educated parents describe how they have not in fact made an active decision to go to university. Instead, they hold to the notion that going to university or college is a natural part of growing up. For children of poorly educated parents things are different. They describe how university is one alternative among many, and list the ways in which their parents have supported and encouraged them, regardless of the choices they have made For the children of poorly educated people, there was often one significant event that prompted them to choose to go to university. In the present study it has been possible to compare how both inheritors and the upwardly mobile describe their first experiences of university and their lives there. It transpired that both groups experienced confusion and indecision, but inheritors develop strategies to handle the ambiguity of the situation, while the upwardly mobile often find it more difficult to deal with the uncertainties. The inheritors outline in broad terms how satisfied they are with their educational situation. This can be seen as a natural part of their habitus. The upwardly mobile, on the other hand, sense to varying degrees that they have changed during their time at university. They remark on how their language, manner, and general attitude have changed</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/eef6d851-5749-4edd-84fc-104f190c9ec1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="HILDING_G5.pdf">https://portal.research.lu.se/files/3388956/1759339.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1348353</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Sociology, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>sociology of education</topic> <topic>social mobility</topic> <topic>diversity in higher education</topic> </subject> <subject authority="lup"> <topic>Sociology (excluding Social Work, Social Anthropology, Demography and Criminology)</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Dissertations in Sociology</title> </titleInfo> <identifier type="issn">1102-4712</identifier> <identifier type="isbn">91-7267-326-5</identifier> <identifier type="oldLupId">1749066</identifier> <part> <extent unit="pages"> <total>200</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-01-17T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>eef6d851-5749-4edd-84fc-104f190c9ec1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:27:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:27:58+02:00</recordDateApproved> </recordInfo> </mods>

Motion estimation, object segmentation and detection are all parts of early vision, but recognition is not. Many of these tasks are formulated as optimization problems and one of the key factors for the success of recent methods is that they seek to compute globally optimal solutions. This thesis is concerned with improving the efficiency and extending the applicability of the current state of the art. This is achieved by introducing new methods of computing solutions to image segmentation and other problems of early vision. The first part studies parametric problems where model parameters are estimated in addition to an image segmentation. For a small number of parameters these problems can still be solved optimally. In the second part the focus is shifted toward curvature regularization, i.e. when the commonly used length and area regularization is replaced by curvature in two and three dimensions. These problems can be discretized over a mesh and special attention is given to the mesh geometry. Specifically, hexagonal meshes are compared to square ones and a method for generating adaptive methods is introduced and evaluated. The framework is then extended to curvature regularization of surfaces. Thirdly, fast methods for finding minimal graph cuts and solving related problems on modern parallel hardware are developed and extensively evaluated. Finally, the thesis is concluded with two applications to early vision problems: heart segmentation and image registration.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8626f0fe-0e95-421a-b851-a18e1d182088</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis.pdf">https://portal.research.lu.se/files/3389191/1760799.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">10823458</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Centre for Mathematical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Computer graphics and computer vision</topic> <topic>Mathematical Sciences</topic> </subject> <relatedItem type="host"> <location> <url>http://www.maths.lth.se/matematiklth/personal/petter/thesis/thesis.pdf</url> </location> </relatedItem> <relatedItem type="host"> <identifier type="isbn">978-91-7473-068-5</identifier> <identifier type="oldLupId">1760796</identifier> <part> <extent unit="pages"> <total>151</total> </extent> </part> </relatedItem> <recordInfo> <recordIdentifier>8626f0fe-0e95-421a-b851-a18e1d182088</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:01+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-13T09:48:22Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:01+02:00</recordDateApproved> </recordInfo> </mods>

In the AR coding region there is a polymorphic CAG repeat encoding a stretch of the amino acid glutamine (Q). The repeat length modulates receptor activity and is normally distributed between 10-30 CAG with a median length of 22 repeats in white men. At the start of this work, a negative linear association between AR function and the CAG repeat number was generally assumed. This assumption was supported by clinical findings in patients with Kennedy’s disease, which is a neuromuscular disorder caused by an abnormally expanded CAG repeat (&amp;gt;40 CAG). However, in vivo data concerning the association between CAG numbers within normal length and androgenic effects were conflicting. As understanding the impact of CAG number on the AR activity is important for proper interpretation of this polymorphism and risk of pathological conditions other than Kennedy’s disease, the purpose of this study was to examine the influence of CAG length, if any, on AR activity.&lt;br/&gt;&lt;br&gt; Firstly an in vitro study was performed. A reporter gene with a human androgen responsive promoter was used in a transactivation assay. The repeat lengths included were 16, 22 and 28 CAG, which represent a short, the median, and a long repeat within the normal human range. The study showed that the AR with median repeat length had the highest activity in vitro. Secondly, the effect of the CAG repeat in relation to two androgen dependent conditions, infertility and PCa, was analysed in two separate meta-analyses. When stratifying the CAG repeats into three groups, shorter than median, median and longer than the median CAG length, the meta-analysis on infertile men showed 20% increased risk of infertility in men harbouring other repeat lengths than the most common. On the other hand, CAG number did not have any effect on PCa risk. &lt;br/&gt;&lt;br&gt; The AR regulates the expression of prostate specific antigen (PSA). Thus the expression of PSA can be used as a marker of AR activity in tissue. We measured the AR protein and PSA amount in human prostate tissue from 19 men with known CAG length. Those who were carriers of 22 CAG had lower AR amount and higher PSA than counterparts with other CAG lengths, but this was not statistically significant, probably due to the small study size. &lt;br/&gt;&lt;br&gt; Taken together, these studies indicate that the median length of the androgen receptor CAG repeat is associated with optimal activity, in vitro and in vivo.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8598fa59-b92c-4039-a9f5-5cee2f6c0dca</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="03.01.11.Final.Ram.HN.pdf">https://portal.research.lu.se/files/3390473/1845334.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1222771</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>androgen receptor</topic> <topic>polymorphism</topic> <topic>CAG polymorphism</topic> <topic>androgen receptor activity</topic> <topic>infertility</topic> <topic>prostate cancer</topic> <topic>androgen receptor function</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-75-4</identifier> <identifier type="oldLupId">1845310</identifier> <part> <detail type="volume"> <number>2011:27</number> </detail> <extent unit="pages"> <total>112</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-04-01T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>8598fa59-b92c-4039-a9f5-5cee2f6c0dca</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-03-02T13:28:02Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:11+02:00</recordDateApproved> </recordInfo> </mods>

The TRIM family is a family of RING (Really Interesting New Gene) proteins, defined through a tripartite motif, containing a RING-domain, one or two B-boxes and a Coiled-coil-domain. The TRIM proteins are involved in diverse biological functions, such as apoptosis, cell-cycle- progression and viral defence. Interferons (IFNs) are pleiotropic cytokines with antiviral, anti-proliferative, proapoptotic and immunmodulatory functions. Similar to TRIM22, many TRIM proteins are upregulated in response to IFNs, and many are involved in defence towards viruses, including TRIM22. TRIM22 has been shown to restrict HIV-1, hepatitis B and encephalomyocarditis virus. p53 is probably one of the most important tumour suppressor genes, and is positioned in the centre of signalling pathways that prevent proliferation and survival of potentially malignant cells. So far only TRIM22 and TRIM19 (PML) have been shown to be upregulated in response to p53, but recently several TRIM proteins have been shown to interact with and regulate p53. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In my thesis, I have characterised the subcellular localisation and the functions of TRIM22. In paper I I show that endogenous TRIM22 localises to both the nucleus and cytoplasm. Furthermore, TRIM22 colocalises with the centrosomes irrespective of cell-cycle-phase, and with the endoplasmatic reticulum in primary cells and in cell-lines. In paper II I show that overexpressed TRIM22 suppresses translation through direct or indirect interaction with the translation initiation factor eIF4E and disruption of the eIF4F-complex. My data suggest that TRIM22 may suppress translation of a subset of mRNAs, particularly dependent on eIF4F for their translation. In paper III I show overexpressed TRIM22 to induce either repressed proliferation or cell-death depending on cellular context. Taken together, my data show cell-death-inducing, antiproliferative, translation-inhibitory effects of TRIM22, consistent with a role both as a tumour suppressor downstream of p53-signalling, and with immunomodulation downstream of IFNs. However, many new questions have been raised and further studies are warranted to understand all aspects of the function of TRIM22.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7d51549a-b12c-4add-a7dc-b4b6001b336f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_TRIM22_final.pdf">https://portal.research.lu.se/files/3390490/2203228.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1243972</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Haematology and Transfusion Medicine</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>TRIM22</topic> <topic>Staf50</topic> <topic>p53</topic> <topic>IFN</topic> <topic>translation</topic> <topic>proliferation</topic> <topic>cell death</topic> </subject> <subject authority="lup"> <topic>Hematology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-51-2</identifier> <identifier type="oldLupId">2203221</identifier> <part> <detail type="volume"> <number>2011:101</number> </detail> <extent unit="pages"> <total>110</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-12-02T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>7d51549a-b12c-4add-a7dc-b4b6001b336f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:11+02:00</recordDateApproved> </recordInfo> </mods>

The studies have been performed within two health care organizations between 2005 and 2009, together with hospital staff. Two questionnaire studies were conducted (n=446 n=505, respectively). A focus group interview study was performed (n=78), and meetings were held in an action research process for applying a questionnaire process at two wards (n=69). The result shows a development process for a multi-dimensional questionnaire, the Work Experience Measurement Scale (WEMS), which can be used to measure work experiences from a salutogenic perspective. WEMS was shown to be a functional workplace health promotion questionnaire with the ability to discriminate between groups. Its psychometric properties support its applicability in health care settings and offer a possibility to measure trends over time regarding employees´ work experiences. A dialogue structure for progress in the questionnaire process is presented. It describes what to precede and how to proceed through a workplace questionnaire process to foster applicability, meaningfulness, and sustainability. Through WEMS, the outcome of work-related Specific Enhancing Resources (SER) may be highlighted and strengthened in workplace activities. When used as a dialogue tool in a continuous questionnaire process, WEMS has the potential of being a useful assessment tool in workplace health promotion. Such a dialogue tool is useful in discussions and tangible for the work of enhancing positive human capabilities and resources (SER) that improve work performance.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Arbetsplatsens positiva sidor kan förbättras genom ett nytt dialogverktyg!&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Nu går det att mäta medarbetares positiva upplevelser av arbete. Vanligtvis kopplas människors upplevelser av arbete samman med stress och ohälsa. Men det går att tänka tvärtom, att istället fokusera på allt det positiva som arbete kan ge. När människor mår bra av sitt arbete, blir de också mer handlingskraftiga. Fram tills nu har det saknats en användbar och engagerande metod för att mäta och driva förbättringsarbeten på arbetsplatser utifrån ett hälsoskapande synsätt. Nu finns det ett nyutvecklat dialogverktyg.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; När en människa går in för att utföra en arbetsuppgift, satsas individuella resurser för att kunna genomföra uppgiften. Resurserna som utnyttjas kan vara fysiska, psykiska, känslomässiga och sociala. Under gynnsamma förhållanden på arbetsplatsen mår medarbetarna bra, de upplever arbetet som positivt och stärkande därför att de resurser som satsats blir ”påfyllda” igen. Medarbetare som mår bra har också ork till att ha drivkraft i sitt arbete. Ett företag eller en organisation kan aktivt arbeta för att främja sådana hälsoskapande förutsättningar så att medarbetarna kan tillägna sig stärkande resurser genom sitt arbete. Medarbetarna kommer då åter att kunna investera sina resurser i arbetsuppgifter eller använda dem för att hantera olika situationer i arbetet. Det behövs alltså metoder för att aktivt och kontinuerligt kunna arbeta med att främja hälsoskapande resurser på en arbetsplats.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ett webbaserat frågeformulär har utvecklats utifrån teorier om arbetshälsa och i samarbete med några sjukhusavdelningar på Ängelholms sjukhus. Det kallas WEMS – Work Experience Measurement Scale (Frågeformulär om upplevelser av arbete och arbetsplats). Frågeformuläret är utformat utifrån ett positivt sätt att se på arbete och fokuserar på arbetets potentiella friskfaktorer istället för enbart riskfaktorer. Det innehåller frågor om medarbetarnas individuella upplevelser av arbete, hur det sociala stödet från arbetskamrater är, hur chefen upplevs agera, hur tiden räcker till för arbetsuppgifterna, vad man kan bestämma själv och hur förändringar genomförs. Frågeformuläret har 32 påståenden som man tar ställning till. Varje medarbetare graderar sin upplevelse från instämmer helt med påståendet till att helt ta avstånd från påståendet. WEMS är också tänkt att användas som ett dialogverktyg för hälsofrämjande arbete på arbetsplatser.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; När ett frågeformulär som WEMS utvecklas, testas frågornas kvalitet med olika mått. Håller de en god kvalitet, förutsätts de också fungera bra i praktiken. De erfarenheter som har gjorts är att förberedelser inför en enkätprocess på en arbetsplats är avgörande för om enkätprocessen kommer att bli lyckad och kännas meningsfull för medarbetarna. Det är betydelsefullt att förankra enkäten hos alla på arbetsplatsen, att utse en kärngrupp av medarbetare med ansvar för att driva enkätprocessen, att diskutera i arbetsgruppen vad en enkätprocess kan bidra med på den specifika arbetsplatsen och därigenom skapa förståelse för hur arbetsgruppen kan arbeta med enkätprocessen. Om en organisation lägger ner tid och pengar på en enkätprocess är det av vikt att den fyller ett syfte för både ledning och medarbetare. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Avhandlingsresultatet har även gett en cirkulär struktur för hur en arbetsgrupp kan arbeta med enkäten WEMS som ett dialogverktyg i en kontinuerlig process. Strukturen består av faser som kan symboliseras med en näckros. Blomman är kärnan där förberedelser och planering börjar. Därefter fortsätter enkätprocessen runt bladet i olika faser, vilka är: besvara enkät, presentera resultat, diskutera resultat, fokusera ett område, definiera och planera förbättringsarbeten, genomföra förbättringsarbeten, reflektera över hur det gick och slutligen påbörja en ny enkätprocess genom att förankra och förbereda på nytt. I steget där enkätresultat diskuteras är det viktigt att lyfta fram vad det är i arbetssituationen som är positivt, vilka stärkande resurser som finns på den aktuella arbetsplatsen och utifrån det också se var det finns brister och behov. I en sådan diskussion kan arbetsgruppen ta hjälp av tre begrepp som kan förklara enkätresultatet på ett tydligare sätt. Dessa är begriplighet, hanterbarhet och meningsfullhet. De tre begreppen kopplat till att förstå arbetssituationen kan gemensamt bidra till att öka medarbetarnas känsla av sammanhang i arbetet. Ett kontinuerligt hälsofrämjande arbete på arbetsplatser kan bli mer användbart, meningsfullt och hållbart, genom att använda WEMS som ett dialogverktyg i processer för att se och förstå vilka resurser som finns på arbetsplatsen, samt hur de kan bevaras och förbättras.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6c2ba13a-137c-4f93-8b76-88c33f2ac393</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Petra_Nilsson_elektroniskspikning.pdf">https://portal.research.lu.se/files/3390867/1700821.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">596014</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Salutogenesis</topic> <topic>workplace health promotion</topic> <topic>Sense of Coherence</topic> <topic>Work Experience Measurement Scale</topic> <topic>Specific Enhancing Resources</topic> <topic>questionnaire process</topic> </subject> <subject authority="lup"> <topic>Health Sciences</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-28-0</identifier> <identifier type="oldLupId">1699408</identifier> <part> <detail type="volume"> <number>2010:112</number> </detail> <extent unit="pages"> <total>159</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-11-19T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>6c2ba13a-137c-4f93-8b76-88c33f2ac393</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:15+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:15+02:00</recordDateApproved> </recordInfo> </mods>

In this mode of operation, the wind turbines are able to vary their power production as long as the total power demand is met. The research investigates how this freedom can be used in order to reduce the fatigue loads experienced by the wind turbines. The problem is studied in a linear-quadratic control setting where the objective is to minimize the total fatigue load experienced by the turbines, while satisfying a requirement on their joint power production. It is shown that, under certain assumptions, the design problem can be drastically simplified. In particular, the computational effort needed to obtain the solution is independent of the number of wind turbines and the only centralized operation required to implement the optimal control law is a single summation. The research also explains the mechanisms that make power allocation schemes useful for load reduction.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Part of the research addresses wake effects in wind farms by developing a low-complexity model of the aerodynamic interaction between wind turbines. The model is used in a series of examples, where the wind turbines coordinate their power productions in order to maximize the power production of the wind farm. The examples indicate that the benefit of power coordination increases with the number of turbines in the wind farm. They also identify the underlying mechanisms behind this effect.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The last topic of the thesis is to investigate the benefits of using preview of the incoming wind speed in order to reduce structural loads on the wind turbine tower. The main focus is to understand how measurement distortion influences the achievable load reduction as well as the required length of preview. Results from high-fidelity simulations based on real wind turbine measurements indicate that the use of preview can lead to a significant reduction of tower fatigue loads and that the length of preview needed to attain the reduction does not exceed a few seconds.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9ff63e87-e754-414d-a21f-275cf2c074b6</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesisDaria.pdf">https://portal.research.lu.se/files/3391164/4442920.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2805562</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>PhD Thesis TFRT-1103</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="issn">0280-5316</identifier> <identifier type="isbn">978-91-7623-004-6 (web)</identifier> <identifier type="isbn">978-91-7623-003-9 (print)</identifier> <identifier type="oldLupId">4438759</identifier> <part> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popsciencePopulärvetenskaplig sammanfattning.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3391162/4442925.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-13T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>9ff63e87-e754-414d-a21f-275cf2c074b6</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-23T09:14:15Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:19+02:00</recordDateApproved> </recordInfo> </mods>

Visual acuity is routinely tested to evaluate visual function in diabetes, but can vary for no obvious reasons and even be normal despite severe vessel abnormalities, and hence less useful for early detection of visual impairment. Until now, no measure has proven to be suitable for identifying early changes in retinal function in diabetes.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Two cohorts were investigated. The first cohort comprised 55 diabetic patients with various degrees of diabetic retinopathy. Using a cross-sectional design, we studied how refraction and visual acuity varied in patients under routine care (Study I), and we assessed limits for significant change in visual fields by use of standard automated perimetry (SAP) and short-wavelength automated perimetry (SWAP) based on short-term test–retest variability (Study II). The second cohort consisted of 81 diabetic subjects with no or mild/moderate diabetic retinopathy. We applied a longitudinal prospective design to explore the correlation between functional change and progression of microvascular abnormalities (Study III), and examined the usefulness of SAP with our limits of significant change for detecting early retinal dysfunction over 3–5 years (Study IV).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In Study I, we demonstrated that refraction was stable in most eyes, and assessments of visual acuity were highly reproducible despite substantial fluctuations in blood glucose levels. In Study II, we defined limits of significant change for SAP and SWAP for diabetic subjects. In Study III, we used the defined limits for change to monitor visual function in diabetes by SAP. After 18 months of follow-up, deterioration was common but improvement was rare, and deteriorated fields were reproducible despite an unchanged degree of retinopathy. In Study IV, up to five years of follow-up, confirmed visual field deterioration in eyes without any retinopathy or with stable mild/moderate retinopathy. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Standard automated perimetry with our new model for detecting change can successfully determine early retinal dysfunction over time in diabetes, which can represent early signs and progression of retinal neurodegeneration.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/48032fb9-76b7-47c3-a522-97d3b63709b8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Min_avhandling_fAPr_elektronisk_pub_med_art.pdf">https://portal.research.lu.se/files/3391457/4580965.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4181260</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>diabetic retinopathy</topic> <topic>visual function</topic> <topic>perimetry</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-013-5</identifier> <identifier type="oldLupId">4580959</identifier> <part> <detail type="volume"> <number>2014:84</number> </detail> <extent unit="pages"> <total>92</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-09-12T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>48032fb9-76b7-47c3-a522-97d3b63709b8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:23+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:23+02:00</recordDateApproved> </recordInfo> </mods>

This applies especially to the emission aspects, much due to increasingly stringent emissions legislations. Carbon dioxide (CO2) is considered an important greenhouse gas, but also unburned hydrocarbons (HC), nitric oxides (NOx) and soot pose environmental as well as health risks. Compared to diesel and petrol fuels, natural gas offers a competitive alternative regarding CO2 emissions as well as availability. High efficiencies and low emission levels can be achieved with lean-burn natural gas engines. However, lean mixtures present a few drawbacks: The flame propagation is slow compared to stoichiometric conditions, which increases the risk of misfire and reduces ignition stability. So, there is a need to improve ignition and enhance flame propagation in spark-ignited engines.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The focus of this work is to study and gain knowledge about what factors are important for reliable ignition of lean methane/air mixtures. This is done through experiments involving advanced, new ignition systems, commercially available as well as newly developed ones. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The first studies were performed with a conventional capacitive discharge ignition (CDI) system in a heavy-duty (HD) natural gas engine. The ignition system produces a pulse train, which can be modified according to the desired spark characteristics and current profile, e.g. multispark, increasing current level or low current and long duration. Sparks with different energy content were tested and how fast the energy was released was also studied. Long duration and quick energy release were found to be more important than high current for stable ignition of lean mixtures. The current level did not show a large importance for the ignition quality.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/e85d6e49-9df1-4f46-881a-d50f95f6d0ca</url> </location> </relatedItem> <originInfo> <publisher>Department of Energy Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>ignition system</topic> <topic>spark energy</topic> <topic>internal combustion engine</topic> <topic>engine</topic> <topic>spark ignition</topic> <topic>natural gas</topic> </subject> <subject authority="lup"> <topic>Energy Engineering</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">8770949</identifier> <part> <extent unit="pages"> <total>45</total> </extent> </part> </relatedItem> <recordInfo> <recordIdentifier>e85d6e49-9df1-4f46-881a-d50f95f6d0ca</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-24T11:47:46Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:30+02:00</recordDateApproved> </recordInfo> </mods>

The difficulties with story recall, compared to the norms of the test and the results of a group of TD children, could be related to problems with explicitness and causal conjunctions. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, the children with CP and the children with SBH represented in this thesis both have pragmatically related problems.

T2D is a heterogeneous disease caused by a complex interplay between multiple genetic, epigenetic and non-genetic factors. The disease is characterised by impaired insulin secretion from pancreatic β-cells and insulin resistance in peripheral tissues. Mitochondrial ATP production by oxidative phosphorylation (OXPHOS) is known to play a critical regulatory role in glucose stimulated insulin secretion (GSIS). The overall aim of this thesis was to explore the influence of genetic and epigenetic variation on OXPHOS, islet function and T2D in humans.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In study I, we identified a single nucleotide polymorphism (SNP) in TFB1M, a nuclear-encoded factor involved in the translational control in mitochondria, that is associated with decreased insulin secretion in response to glucose, increased future risk of T2D, and reduced expression of TFB1M in human pancreatic islets. In mice with a heterozygous deficiency of Tfb1m and in clonal β-cells where Tfb1m had been silenced, we found that reduced levels of TFB1M caused impaired OXPHOS and, consequently, reduced insulin secretion. This study concludes that deficiency in TFB1M contributes to the pathogenesis of T2D by causing impaired insulin secretion. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In study II, we showed that SNPs located adjacent to OXPHOS genes are nominally associated with decreased GSIS. Therefore, we cannot rule out the possibility that SNPs in or near genes involved in OXPHOS may influence β-cell function.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In study III, we demonstrated that a set of OXPHOS genes is down-regulated in pancreatic islets from patients with T2D compared to donors not diagnosed with diabetes. Islet expression of multiple OXPHOS genes correlated positively with GSIS. This result suggests that decreased expression of OXPHOS genes in pancreatic islets may contribute to T2D by impaired GSIS.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In study IV, we performed a genome-wide methylation quantitative trait locus (mQTL) analysis to assess the effects of SNPs on DNA methylation in human pancreatic islets. Our results demonstrate that DNA methylation in pancreatic islets is under the control of genetic variability, suggesting the importance of integrating genetic and epigenetic mechanisms when studying the underlying biological effects on complex human diseases, such as T2D. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Taken together, genetic and epigenetic influence on pancreatic islet function and mitochondrial OXPHOS may be involved in the pathogenesis of T2D by affecting insulin secretion.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Diabetes är en grupp av sjukdomar som kännetecknas av förhöjda halter av glukos (socker) i blodet. Förekomsten av diabetes ökar i snabb takt i hela världen. År 2011 var 366 miljoner människor drabbade av diabetes, och denna siffra beräknas till 522 miljoner år 2030 om ingen avgörande åtgärd genomförs. Typ 2 diabetes är den vanligaste formen av diabetes och utgör ungefär 90 % av alla diabetesfall. En ökad förekomst av typ 2 diabetes är starkt förknippad med ökad grad av fetma, en konsekvens av en livsstilstrend med högre energiintag och mindre motion. Kroniskt höga blodglukoshalter som ses vid diabetes kan leda till utveckling av en rad komplikationer, till exempel njurproblem, synfel och kardiovaskulära sjukdomar, varav den sistnämnda är en av de största dödsorsakerna vid typ 2 diabetes. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Människokroppen strävar efter att hålla blodglukoshalten på en jämn nivå. Stigande glukoshalter i blodet, till exempel efter en måltid, regleras med hjälp av hormonet insulin. Insulin utsöndras från beta-celler som finns i de Langerhanska öarna i bukspottskörteln. Insulins målvävnader är skelettmuskler och fettväv, där det stimulerar glukosupptag från blodet, samt levern där det minskar glukosproduktion. Glukos som tas upp av kroppens celler används för att producera energi. Typ 2 diabetes uppstår på grund av defekter i insulinfrisättningen från beta-cellerna och/eller minskad effekt av insulin i målvävnaderna, vilket leder till förhöjda nivåer av glukos i blodet. Allt fler bevis tyder dock på att försämrad insulinfrisättning är den stora boven i sjukdomsprocessen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Frisättning av insulin är en komplicerad process där beta-cellerna fungerar som glukossensorer. Vid ökade halter av glukos i blodet tas detta upp av beta-cellerna och spjälkas till energi i form av ATP-molekyler. Denna energiproduktion sker i cellernas mitokondrier, vars viktigaste funktion är att producera ATP. Mitokondriell ATP-produktion är i sin tur den huvudsakliga utlösaren av insulinfrisättning från beta-cellerna. Om energiproduktionen i mitokondrien inte fungerar optimalt kan frisättningen av insulin försämras, vilket leder till ökad risk för typ 2 diabetes. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De bakomliggande orsakerna till typ 2 diabetes är ännu inte helt kända, men både ärftliga och miljöbaserade faktorer påverkar risken att utveckla sjukdomen. Trots att icke-genetiska faktorer såsom fetma och fysisk inaktivitet spelar roll i utvecklingen av typ 2 diabetes, utvecklar inte alla som är utsatta för dessa riskfaktorer sjukdomen. En stark familjehistoria av typ 2 diabetes tyder på att det finns en genetisk disposition för sjukdomen. Vårt arvsanlag är uppbyggt av en kedja av DNA-molekyler, där ordningen på beståndsdelarna i DNA-sekvensen utgör den genetiska koden. Koden är konstant över tid och likadan i alla kroppens celler. Kroppens celler innehåller två olika DNA. Cellkärnans DNA utgör den stora merparten av arvsmassan, medan mitokondriens DNA utgör en liten mängd. Mitokondriens DNA kodar 13 gener vilka är helt nödvändiga för att mitokondrien ska kunna tillverka cellernas ATP. Mitokondrien består även av ett flertal enheter som kodas av cellkärnans DNA. Flera genetiska variationer som kan öka risken för typ 2 diabetes har hittills hittats. Genom att identifiera genetiska riskfaktorer för typ 2 diabetes och utvärdera vilken funktionell roll genen har i kroppen kan man inhämta viktig information om de underliggande mekanismerna bakom sjukdomsutvecklingen. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I den här avhandlingen beskrivs fyndet av en genvariant vilken ökar risken för typ 2 diabetes. Genen kallas TFB1M och är en translationsfaktor som styr uttrycket av de tretton generna som det mitokondriella DNAt kodar. Därmed påverkar genen ATP-produktionen och vidare insulinfrisättningen från beta-cellerna i bukspottskörteln. Genom analyser i befolkningsstudier, studier i mänsklig vävnad, i försöksdjur samt i odlade celler kan vi påvisa effekten av genen och dess involvering i risken för utveckling av typ 2 diabetes. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har ytterligare identifierat två genetiska variationer som verkar ha samband med försämrad insulinfrisättning hos människa. Båda dessa varianter finns i varsin region av vår arvsmassa. Dessa regioner innehåller gener som är involverade i mitokondriens ATP-produktion. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har även studerat uttrycket av gener som är involverade i cellernas energiproduktion i de Langerhanska öarna. Både gener som kodas från cellkärnans DNA såväl som från mitokondriens DNA studerades. Genom att analysera till vilken nivå dessa gener är uttryckta i patienter med typ 2 diabetes och jämföra dem mot individer som inte har diagnosen diabetes kan man få en bättre förståelse för vad som reglerar dessa geners uttryck och till vilken del de är involverade i sjukdomsutvecklingen. Vi fann att ett flertal gener, som är involverade i mitokondriens ATP-produktion, har lägre genuttryck i de Langerhanska öarna hos patienter med typ 2 diabetes. Vi upptäckte också att ett minskat uttryck av dessa gener bidrog till försämrad insulinfrisättning. De Langerhanska öarna i bukspottskörteln innehåller beta-celler som utsöndrar insulin, och denna vävnad är därmed viktig att studera vid typ 2 diabetes.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Epigenetik är ett fenomen som kan påverka när och hur olika arvsanlag aktiveras. I kontrast till genetiken kan epigenetiska förändringar variera mellan olika celler och över tid. Epigenetiken ändrar inte den genetiska koden, utan involverar istället små ovanpåliggande kemiska förändringar av DNAt som gör att arvsmassan tolkas och uttrycks på olika sätt. DNA-metylering är ett exempel på en så kallad epigenetisk förändring. Det är en reversibel process, där en metylgrupp (-CH3) kan binda till DNA-sekvensen och tas bort igen. Beroende på när och i vilka celler i kroppen DNA-metyleringen sker kan denna epigenetiska förändring påverka hur arvsanlaget uttrycks. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att få en djupare förståelse för regleringen av arvsanlaget, valde vi att studera hur genetisk variation påverkar DNA-metylering i de Langerhanska öarna hos människa. Vi undersökte hela arvsmassan, det vill säga helgenomsanalys, för att identifiera genetiska variationer som kan påverka bindningen av metylgrupper till DNA-sekvensen. Vi fann att sådan variation påverkar DNA-metylering av flera gener, vilket kan ha betydelse för genuttryck och insulinfrisättning i de Langerhanska öarna. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammantaget har vi studerat olika gener och mekanismer som är involverade i typ 2 diabetes, vilket har lett till ökad förståelse av den komplexa bakgrund som bidrar till utveckling av sjukdomen. Genom denna ökade förståelse vill vi bidra till att nya vägar för att behandla eller förebygga typ 2 diabetes utvecklas.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c749e464-9881-454c-b02d-cbd5493664fa</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Anders_H_Olsson.pdf">https://portal.research.lu.se/files/3392142/2539150.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">11953874</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Type 2 Diabetes</topic> <topic>Genetics</topic> <topic>Epigenetics</topic> <topic>Human Pancreatic Islets</topic> <topic>Oxidative Phosphorylation</topic> <topic>Insulin Secretion</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-04-3</identifier> <identifier type="oldLupId">2539089</identifier> <part> <detail type="volume"> <number>2012:42</number> </detail> <extent unit="pages"> <total>66</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-06-01T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>c749e464-9881-454c-b02d-cbd5493664fa</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:33+02:00</recordDateApproved> </recordInfo> </mods>

The gene codes for a protein that serve as chloride channel. In cystic fibrosis, this protein is lacking or has a defect function resulting in a thick and sticky mucus of the airways. The altered airway environment promotes mucus and growth of pathogenic bacteria. A common pathogen is Pseudomonas aeruginosa that often colonizes the lungs of adult cystic fibrosis patients and is associated with a poor diagnosis. The host defense fails to eradicate the bacteria and instead a prolonged inflammatory response, including excessive recruitment of neutrophils, confers damage to the lungs. To date, several theories exist of why there is an impaired bacterial clearance in the airways of cystic fibrosis patients. Increased salt concentration, reduced depth and pH of the thin fluid lining the epithelial cells are examples. In this thesis, we have examined different mechanisms impairing the host defense in cystic fibrosis. First, we describe that the growth factor midkine is expressed in the airways of cystic fibrosis patients and that it has antibacterial activity against P. aeruginosa. However, both salt and pH alterations reduced the antibacterial activity of midkine. It was also cleaved into smaller fragments by elastases from neutrophils and P. aeruginosa. In a second study, we show that the chemokine MIG/CXCL9 is expressed in the airways of cystic fibrosis patients and that it has antibacterial activity against P. aeruginosa. MIG/CXCL9 was cleaved into three smaller fragments by elastase of P. aeruginosa, that all had reduced antibacterial activity against P. aeruginosa. The degradation also resulted in a reduced recruitment of other immune cells that are involved in eliminating P. aeruginosa. In a third study, we showed that the negatively charged protein, osteopontin is expressed in the airways of cystic fibrosis patients. Interestingly, osteopontin binds to and inhibits the antibacterial activity and receptor activating properties of several ELR-negative CXC chemokines. This is not the case for the neutrophil recruiting ELR-positive CXC chemokines. These interactions can result in an accumulation of neutrophils in the airways and also a reduced antibacterial activity. Lastly, we showed that the neutrophil recruiting chemokine GCP-2/CXCL6 is expressed in the airways of cystic fibrosis patients. GCP-2/CXCL6 binds to free DNA but, its antibacterial activity and receptor activating properties were not affected by this interaction, while the chemotactic properties were slightly decreased. Taken together, this thesis demonstrates several novel mechanisms that explain how the airway immune system is compromised in cystic fibrosis.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Cystisk fibros (CF) är en ärftlig sjukdom som orsakas av en defekt jonkanal. Denna defekt ger upphov till en onormal saltbalans i kroppen och följderna blir många. I lungorna och magtarmkanalen produceras ett väldigt segt slem vilket täpper till luftvägarna och medför andningssvårigheter. De slemfyllda lungorna klarar inte av att transportera upp slemmet och istället stannar slemmet kvar i lungorna där det utgör det en grogrund för bakterier att frodas i. &lt;br/&gt;&lt;br&gt; Patienter som lider av CF besväras ofta av infektioner i luftvägarna men det är olika slags bakterier som är vanliga beroende på patientens ålder. Varför det är på detta vis vet man inte. En särskilt besvärlig bakterie heter Pseudomonas aeruginosa och drabbar oftast patienter med CF som är lite äldre.&lt;br/&gt;&lt;br&gt; Vita blodkroppar kommer till lungorna för att eliminera bakterierna. Tyvärr är denna funktion ineffektiv och det blir en ansamling av vita blodkroppar som dör och deras arvsmassa (DNA) bidrar till ett segt luftvägsslem som är ett stort bekymmer. &lt;br/&gt;&lt;br&gt; Vid ett friskt tillstånd kan immunförsvaret ta hand om dessa sjukdomsframkallande bakterier. Men vad händer med immunförsvaret vid cystisk fibros som gör att infektioner i lungorna uppstår? &lt;br/&gt;&lt;br&gt; Det finns flera teorier om varför lungorna drabbas av dessa infektioner, och länge har det spekulerats om ökade saltkoncentrationer i den tunna vätskan som täcker luftvägarna. Denna tunna vätska innehåller massvis med antibakteriella proteiner och normalt sett skyddar den lungorna från sjukdomsframkallande bakterier. Ökade saltkoncentrationer i den tunna vätskan förstör de antibakteriella proteinerna så att de längre inte har någon effekt. Nya rön har visat att det dessutom finns en pH-förskjutning i den tunna vätskan hos cystisk fibros patienter och att denna pH-förskjutning förstör de antibakteriella proteinernas aktivitet i lungorna. &lt;br/&gt;&lt;br&gt; I delarbete I har vi kunnat visa att tillväxtfaktorn Midkine, uttrycks i luftvägarna vid cystisk fibros och att den har antibakteriell effekt mot P. aeruginosa. Både salt- och pH-förskjutningar minskar midkines antibakteriella effekt mot P. aeruginosa. Midkine klyvs även till mindre fragment av enzymer som produceras av P. aeruginosa och neutrofila granulocyter. &lt;br/&gt;&lt;br&gt; I delarbete II har vi kunnat visa att ett ämne som lockar till sig vita blodkroppar (en så kallad kemokin), MIG/CXCL9 uttrycks i luftvägarna vid cystisk fibros och att den har antibakteriell effekt mot P. aeruginosa. Till skillnad från midkine, påverkas inte MIG/CXCL9 särskilt mycket av salt- och pH-förskjutningar. Däremot klyvs MIG/CXCL9 av enzymer som produceras av P. aeruginosa och neutrofila granulocyter till mindre fragment, som har sämre antibakteriell effekt mot P.aeruginosa än fulllängds-proteinet. Detta bidrar samtidigt till en minskad rekrytering av andra celler som också är involverade i att eliminera P. aeruginosa.&lt;br/&gt;&lt;br&gt; I delarbete III har vi kunnat visa att det negativt laddade äggviteämnet osteopontin uttrycks i luftvägarna vid cystisk fibros. Osteopontin binder till och blockerar den antibakteriella effekten av flera kemokiner, men inte de som attraherar ett slags vita blodkroppar (neutrofila) från blodbanan till lungorna. Detta resulterar i en ansamling av neutrofiler och ger samtidigt minskad antibakteriell aktivitet. &lt;br/&gt;&lt;br&gt; I delarbete IV har vi kunnat visa att den neutrofil-rekryterande kemokinen GCP-2/CXCL6 uttrycks i luftvägarna vid cystisk fibros. GCP-2/CXCL6 binder till fritt DNA, men dess antibakteriella och neutrofil-rekryterande aktiviteter påverkas inte avsevärt mycket av denna interaktion. &lt;br/&gt;&lt;br&gt; I avhandlingsarbetet har vi visat på några nya aspekter på hur immunförsvaret i luftvägarna är påverkat och fungerar dåligt vid CF. En förhoppning är att dessa studier tillsammans med annan forskning kan bidra till en bättre behandling för människor som lider av CF.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/053562e4-03f0-4f26-b455-58c410472d56</url> </location> </relatedItem> <originInfo> <publisher>Lungmedicine and allergology</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-175-0</identifier> <identifier type="oldLupId">7869065</identifier> <part> <detail type="volume"> <number>2015:96</number> </detail> <extent unit="pages"> <total>76</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>http://lup.lub.lu.se/record/5448515</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://lup.lub.lu.se/record/4908681</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://lup.lub.lu.se/record/4614894</url> </location> </relatedItem> <relatedItem type="link"> <location> <url>http://lup.lub.lu.se/record/3956309</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-10-09T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>053562e4-03f0-4f26-b455-58c410472d56</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:34+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:34+02:00</recordDateApproved> </recordInfo> </mods>

RIT has been effective in lymphoma but less successful in solid tumors. mAbs slowly diffuse from the vasculature into and through solid tumors, resulting in slow, limited accretion of antibodies. The outcome is a low tumor-to-normal tissue (T/N) activity ratio. Hence high activities (MBq) for therapy are needed to achieve sufficient tumor dose. The dose-limiting factor is myelotoxicity caused mainly by slow clearance of mAbs from the circulation.&lt;br/&gt;&lt;br&gt; Methods: Extracorporeal depletion of radioactivity in blood is one strategy to increase T/N ratios and reduce toxicity . Extracorporeal affinity adsorption treatment (ECAT) is based on the biotin-avidin system utilizing the high-affinity interaction between avidin and biotin. Antibodies are radiolabeled and biotinylated using a trifunctional protein reagent. By passing whole blood extracorporeally through a column coated with avidin, radioimmunoconjugates are adsorbed in the column and eliminated from the circulation. &lt;br/&gt;&lt;br&gt; Aim: To investigate and optimize ECAT in an imunocompetent syngeneic rat tumor model. &lt;br/&gt;&lt;br&gt; Results: We established a suitable model for evaluation of the toxicity-reducing potential of ECAT, strategies to increase administered activities, and for the comparison of different radionuclides. In addition we developed a new technique for gaining blood access via the tail which requires no surgery, causes minimal stress to the animals and allows several animals to be studied simultaneously. ECAT reduces myelotoxicity associated with RIT. The timing of ECAT influences the duration and degree of bone marrow recovery and toxicity-reducing effect. The maximal tolerable dose of 177Lu- or 90Y-labeled RIC can be increased 2.0 or 1.5 times, respectively. ECAT is efficient as a means of removing biotinylated antibodies in a two-step pretargeting therapy concept, and would probably also be efficient as a clearing step in pretargeting strategies employing streptavidin-conjugated mAbs followed by the administration of radiolabelled biotin.&lt;br/&gt;&lt;br&gt; Our rat tumor model with the tumor cell line used is not optimal for the evaluation of the therapeutic effect of high-dose RIT in combination with ECAT because of the favorable radiation “sensitivity” ratio of rats, which results in efficient tumor therapy even without ECAT. RIT with 90Y and 177Lu seems not to be effective on microscopic cancer disease due to the radiation energy being deposited outside the tumor cell cluster.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/76ff5a5a-0dcc-43eb-a18f-253e543f1c81</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-86-5</identifier> <identifier type="oldLupId">1048927</identifier> <part> <detail type="volume"> <number>2008:33</number> </detail> <extent unit="pages"> <total>120</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-04-10T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>76ff5a5a-0dcc-43eb-a18f-253e543f1c81</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:39+02:00</recordDateApproved> </recordInfo> </mods>

Previous studies have shown that these disturbances can be detected non-invasively as distinctive appearances of the orthogonal P wave using signal-averaged P-wave analysis (PSAECG). Orthogonal recordings (VCG) are however scarce in clinical practice for practical reasons. The aim of the presented study was to explore the possibility of mathematically transforming conventional 12-lead ECGs into orthogonal P-wave data with preserved information content regarding P-wave morphology. If feasible, the method would then be used to analyse P-wave data from healthy adult men and women of all ages in order to provide a first reference material of the “normal” P wave for future studies.&lt;br/&gt;&lt;br&gt; Study I evaluated the feasibility of lead conversion (ECG into VCG) in both healthy individuals and arrhythmia patients. The study compared P waves from recorded and derived VCG and it was found that information of interatrial conduction disturbances is preserved. Study II further evaluated this method in a similar material. Different variations of ECG data mimicking true clinical conditions were explored regarding the preservation of P-wave data. It was found that PSAECG is a robust analysis method also in a proposed clinical setting. &lt;br/&gt;&lt;br&gt; Study III and IV were devoted to the analysis of P-wave data retrieved from a large material of healthy individuals using the previously validated method. The main finding of Study III was that P-wave morphologies previously observed in arrhythmia patients were commonly observed also in this normal population. The changes were, however, mostly found in the higher age groups, which is in keeping with the known fact that many arrhythmias are more common with increasing age. In Study IV, a long-term follow-up of the “normal” P-wave morphology was conducted, where it was found that P-wave morphology is mostly unaltered after three years. However, in a small number of individuals, discrete changes were observed that support the theory that age-related changes influence interatrial conduction and may implore susceptibility for developing arrhythmias.&lt;br/&gt;&lt;br&gt; The presented study adds to the increasing knowledge about interatrial conduction. It provides a validated method for non-invasive exploration of he impulse propagation and also a reference material of the “normal” signal-averaged P-wave morphology.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/99692420-8362-4d20-8fea-9f0b5e66391a</url> </location> </relatedItem> <originInfo> <publisher>Faculty of Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>signal-averaged</topic> <topic>interatrial conduction</topic> <topic>orthogonal</topic> <topic>P-wave</topic> <topic>ECG</topic> <topic>healthy</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-42-4</identifier> <identifier type="oldLupId">1391665</identifier> <part> <detail type="volume"> <number>2009:54</number> </detail> <extent unit="pages"> <total>152</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-27T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>99692420-8362-4d20-8fea-9f0b5e66391a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:28:51+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-11-25T09:50:59Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:28:51+02:00</recordDateApproved> </recordInfo> </mods>

To do this it is necessary to learn more about the prognostic and treatment predictive factors that determine the risk of relapse and response to a certain mode of treatment. This thesis describes studies on the effect of amplified in breast cancer 1 (AIB1), a coactivator of the oestrogen receptor, on prognosis and tamoxifen response through a controlled trial on premenopausal patients randomized to tamoxifen or a control group. AIB1 was found to be a negative prognostic factor, although patients with high AIB1 responded very well to tamoxifen. The findings were validated in two independent cohorts, one consisting of premenopausal patients not receiving tamoxifen, and the other of pre- and postmenopausal patients receiving tamoxifen.&lt;br/&gt;&lt;br&gt; It has recently been suggested that the effect of AIB1 is modified by paired box 2 gene product (PAX2). PAX2 is a transcription factor important during embryogenesis, and may also play a role in carcinogenesis. This is the first time PAX2 has been investigated in well-defined cohorts of patients receiving or not receiving tamoxifen. PAX2 was not found to affect prognosis on its own, or to modify the effect of AIB1.&lt;br/&gt;&lt;br&gt; The second part of this thesis focuses on contralateral breast cancer (CBC). Within their lifetime, previous breast cancer patients have a 2-20% risk of developing a second tumour in the contralateral breast. From the trial on premenopausal patients randomized to tamoxifen or control, it was found that without tamoxifen 12% developed CBC within a median follow-up period of 14 years. This risk was even higher in the youngest women (&amp;lt;40 years), in which 20% developed CBC. Treatment with tamoxifen reduced the risk by 50% in all patients, and by 90% in the youngest women.&lt;br/&gt;&lt;br&gt; Since CBC is still a rather rare event, previous studies are often small or based only on register data. Detailed patient, tumour and treatment information has been collected for a large cohort (&amp;gt;700) of patients with CBC in the Southern Healthcare Region of Sweden. From these data it was found that a short time interval between tumours was associated with a poorer prognosis, especially in young patients. This could indicate that some of these CBCs are in fact metastases of the first tumour, and would thus require different treatment. It could also be that tumours that develop soon after previous treatment have developed resistance to treatment and are of a more aggressive phenotype.&lt;br/&gt;&lt;br&gt; Finally, it was found that patients who first noticed symptoms of their CBC themselves had a higher risk of developing metastases than patients diagnosed by mammography or clinical examination in a follow-up programme. The difference in prognosis in relation to mode of detection remained even when the time interval between tumours was ≥10 years, indicating that a long follow-up period is valuable.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Varje år drabbas cirka 8000 svenska kvinnor av bröstcancer, och antalet nyinsjuknade ökar årligen med någon procent. I Sverige idag finns fler än 90 000 kvinnor som har avslutat eller är under behandling för sjukdomen. Med hjälp av nya återfallsförebyggande läkemedel har prognosen kraftigt förbättrats och 5-årsöverlevnaden är nästan 90 %. Den stora utmaningen i dagens bröstcancervård är dock att veta vilken patient som kommer att ha nytta av vilken typ av behandling. För att förhindra återfall hos några få behandlas idag många kvinnor ”i onödan”, eftersom de även utan behandling aldrig hade fått något återfall. Andra får återfall trots behandling och hade således varit bättre hjälpta av andra åtgärder. Genom att på förhand kunnat säga vilken patient som har nytta av vilken typ av behandling hade vi kunnat spara mycket onödigt lidande, tid, pengar och även liv.&lt;br/&gt;&lt;br&gt; Av samtliga bröstcancrar uttrycker cirka tre fjärdedelar receptorer för det kvinnliga könshormonet östrogen, vilket betyder att de är beroende av östrogen för att tillväxa och överleva. Blockering av östrogentillförseln har då visat sig vara en mycket effektiv behandlingsmetod. Detta kan göras antingen genom att blockera tumörcellernas receptorer eller genom att minska östrogennivåerna i kroppen. Tamoxifen är ett läkemedel som binder till receptorn istället för östrogen och förhindrar östrogenets effekter i bröstvävnaden. Behandling med tamoxifen minskar återfallsrisken med 50 % för opererade kvinnor och kan även hålla tillbaka sjukdomen hos dem med spridd bröstcancer. Ändå finns det de som inte svarar på behandlingen och vid spridd sjukdom utvecklar i stort sett alla med tiden resistens (det vill säga att behandlingen inte längre är verksam mot cancern). Vi har undersökt två faktorer, som man tror kan påverka prognosen vid bröstcancer, samt hur man kommer att svara på tamoxifen. AIB1 är en faktor som hjälper till att aktivera östrogenreceptorn och man har tidigare trott att den eventuellt kunde vara involverad i resistensutveckling mot tamoxifen. Vi har för första gången sett att även om kvinnor som har högt uttryck av AIB1 i sina tumörer har en sämre prognos, så har de stor nytta av tamoxifen-behandling. Att ett högt AIB1 ger en ökad risk för återfall och en kortare livslängd har vi kunnat visa i två oberoende stora patientgrupper. Det gör AIB1 till en mycket intressant faktor att studera vidare och i framtiden eventuellt kunna rikta nya läkemedel mot.&lt;br/&gt;&lt;br&gt; Nyligen föreslogs i cellinjer att effekten av AIB1 påverkas av en annan faktor, PAX2, och att de gemensamt avgör hur tumören kommer svara på tamoxifen. PAX2 är viktig under fosterlivet för utveckling av bland annat hjärna och njurar. Man har också sett att överuttryck av PAX2 kan förhindra celldöd och leda till cancerutveckling. Detta är första gången som PAX2 studeras i en större grupp av kvinnor med bröstcancer, som antingen fått eller inte fått tamoxifen. Vi kan visa att för bröstcancerpatienter verkar inte PAX2 ensamt påverka prognosen. Inte heller förändrar PAX2 den prognostiska effekten av AIB1.&lt;br/&gt;&lt;br&gt; Den andra delen av denna avhandling handlar om kvinnor som först fått en tumör i ena bröstet och sedan en i andra bröstet, så kallad kontralateral bröstcancer (CBC). För dem som botas från sin första bröstcancer är risken att drabbas av CBC 2-6 ggr högre jämfört med risken för befolkningen i övrigt att drabbas av bröstcancer. Faktorer som ökar risken är ung ålder, ärftlighet samt en viss form av bröstcancer som kallas lobulär.&lt;br/&gt;&lt;br&gt; I en studie där unga bröstcancerpatienter (före klimakteriet) lottats till att få behandling med tamoxifen eller inte, kunde vi se att utan tamoxifen utvecklade 12 % av kvinnorna CBC inom 14 år. Bland de yngsta kvinnorna (&amp;lt;40 år) var dock risken så hög som 20 %. Behandling med tamoxifen minskade risken med 50 % hos samtliga patienter, och med så mycket som 90 % hos de allra yngsta. Riskminskningen sågs oberoende av om den första bröstcancern uttryckte östrogenreceptorer eller ej. Normalt används inte tamoxifen till kvinnor vars tumörer inte uttrycker östrogenreceptorer, eftersom man vet att läkemedlet inte hjälper mot den typen av tumör. Av denna studie kan man dock dra slutsatsen att vissa av dessa kvinnor, som har en hög risk för CBC, kanske ändå hade haft nytta av tamoxifen för att förebygga att de får en ny tumör. Att överväga att ge även dem läkemedlet är dock kontroversiellt, eftersom det inte hjälper mot den tumör de för tillfället behandlas för, samt då det trots allt finns en risk för biverkningar.&lt;br/&gt;&lt;br&gt; Även om risken för CBC är relativt hög för kvinnor som tidigare behandlats för bröstcancer, är sjukdomen totalt sett i befolkningen inte så vanlig. Tidigare studier är därför ofta små eller enbart baserade på registerdata. Vi har samlat in journalmaterial från över 700 kvinnor med CBC i södra Sverige. Där finns information om bakgrundshistoria, hur tumörerna upptäckts, hur de behandlats och hur det sedan gått. Från detta har vi kunnat se att kvinnor som fått sin andra tumör nära inpå den första har en sämre prognos. Orsaken till detta är oklar. En förklaring kan vara att vissa av dessa tumörer inte är en ny cancer utan en spridning av den första. Detta hade i så fall krävt en helt annan typ av behandling. En annan förklaring kan vara att om en ny tumör lyckas uppstå trots att man nyligen genomgått behandling för den första, är den nya tumören mer aggressiv och resistent mot den behandling som redan givits.&lt;br/&gt;&lt;br&gt; Slutligen såg vi även att kvinnor vars CBC diagnosticerades inom ett uppföljningsprogram (med mammografi-röntgen eller vid undersökning av en läkare) hade en lägre risk att senare utveckla spridd sjukdom jämfört med de kvinnor som själva upptäckte tumör nr 2. Detta gällde även om lång tid (≥10 år) förflutit mellan tumörerna och tyder på att regelbunden uppföljning efter bröstcancerbehandling kan vara av värde.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3c985e6d-8cde-491d-8211-0bf0fb1bb663</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_120625.pdf">https://portal.research.lu.se/files/3397990/2971411.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1223012</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Oncology, Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Breast cancer</topic> <topic>prognosis</topic> <topic>treatment prediction</topic> <topic>endocrine treatment</topic> <topic>tamoxifen</topic> <topic>coactivator</topic> <topic>AIB1</topic> <topic>PAX2</topic> <topic>SRC</topic> <topic>contralateral breast cancer</topic> <topic>premenopausal</topic> <topic>randomized trial</topic> <topic>mode of detection</topic> <topic>mammography.</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-15-9</identifier> <identifier type="oldLupId">2971371</identifier> <part> <detail type="volume"> <number>2012:52</number> </detail> <extent unit="pages"> <total>105</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-09-28T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>3c985e6d-8cde-491d-8211-0bf0fb1bb663</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:01+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:01+02:00</recordDateApproved> </recordInfo> </mods>

Subsets of bigger and mushroom-shaped hippocampal dendritic spines contain tubules and cisterns of endoplasmic reticulum (ER) that are connected to the soma and dendrites of the neuron. These ER containing spines differ in their ability to retain ER. We hypothesized a functional coupling of the ER to the plasma membrane (PM) via &lt;br/&gt;&lt;br&gt; protein-protein interaction at specialized junctions, which we believe to anchor ER within spines. Although the molecular composition of such an ER-plasma membrane junction (ERPMJ) is yet to be elucidated, we showed that a subset of ERPMJs containing type I transmembrane proteins sensitive to phorbol ester induced metalloproteinase and subsequent gamma-secretase mediated remodelling, and that these proteins may be involved in regulating spine ER dynamics. The gamma-secretase is a multimeric complex with presenilin protein as the catalytic component. Findings have implicated mutations in the presenilin genes clinically associated to familial Alzheimer’s disease (FAD) with altered store-operated calcium entry (SOCE) response. SOCE is a cellular homeostatic mechanism that is activated to restore the depleted ER calcium store via specialized store-operated calcium channels (SOC) localized in the PM. With SOCE-inducing protein STIM1, we explored the effect of a FAD M146V mutation in presenilin-1 (PS1) on spine ER dynamics as well as on STIM1 function. In EGFP-STIM1-expressing hippocampal neurons established from wild-type and FAD PS1 mutant mice, we used 3,5-dihydroxyphenylglycine (DHPG) and carbachol, agonist of type I metabotropic glutamate receptors and muscarinic acetylcholine receptors to trigger calcium release from the ER via IP3R. Surprisingly, STIM1 activation appeared not to be affected by the PS1-M146V mutation although SOCE was impaired. Separately, we showed that DHPG or carbachol stimulation in PS1-M146V neurons led to a significant ER loss from spines that was exclusively mediated by mechanisms controlling ER entry into spines. We hypothesized that the PS1-M146V mutation altered yet to be elucidated mechanisms regulating ER entry into spines, and which may well contribute to synaptic dysfunction in FAD. Looking forward, there is value in future research to elucidate novel molecules and signaling pathways vis-a-vis gamma-secretase and presenilin activity to spine ER dynamics.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Till och med kroppens allra enklaste celler är så avancerade att vi inte förstår i detalj hur de fungerar eller hur de påverkar kroppen. Nervceller tillhör kroppens mer avancerade celler och vi får erkänna att all den kunskap vi har om dem är mindre än vad som finns att veta. Komplexiteten hos hjärnan är mångfalt större för nervcellerna kommunicerar blixtsnabbt med varandra och med hjärnans andra celler.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den här avhandlingen gäller funktionen hos ytterst små delar av nervceller från hippokampus som är ett område i hjärnan som är viktigt för minne och inlärning. De små delarna är dels vad som kallas spines och är utskott från dendriten dels endoplasmatiskt retikel: en inre organell som finns i nästan hela nervcellen; bland annat i vissa spines.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Spines är platsen där nervcellen tar emot information från andra nervceller – den utgör alltså en del av en synaps. De synapser som finns på spines är viktiga för minne och inlärning eftersom de kan fungera som egna ”logiska enheter” där en första behandling av inkommande information sker. Spines är utrustade med receptorer för neurotransmittorer som släpps ut från den anslutande nervcellen och i spines kan frekvensen av neurotransmittorfrisättningen påverka vilka biokemiska reaktioner som startar och spines kan också jämföra hur aktiveringen av dess egna receptorer stämmer överens med nervcellens totala aktivitetsgrad.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Kalciumjoner spelar en mycket viktig roll i hur spines behandlar information. Det är här endoplasmatiskt retikel (ER) kommer in för det är en organell som lagrar kalcium inuti cellen och är utrustad med kalciumkanaler för att släppa ut kalcium i små eller stora doser för att på så vis styra olika biokemiska processer. Kalciumjoner kan också komma in i nervcellen via kanaler i cellens ytterhölje – plasmamembranet och störningar i hur de här kanalerna eller ER-kanalerna fungerar leder till störd funktion hos nervceller och därmed hos hjärnan i stort.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Avhandlingen inleds med ett arbete som visar att ER-fördelning till spines delvis styrs av ett enzym som heter gamma (γ)-sekretas. En av komponenterna i γ-sekretas är ett protein som heter presenilin-1 och det är kopplat till en ärftlig form av Alzheimers sjukdom. Att γ-sekretas styr fördelningen av ER till spines är ett viktigt fynd eftersom det är känt sedan tidigare att Alzheimers sjukdom är förknippat med störd kalciumsignalering kopplad till ER och även störd synapsfunktion. Detta första fynd har lett vidare till två ytterligare arbeten där vi i större detalj har undersökt dels ER-fördelning till spines dels några av de ER-kalciummekanismer som tidigare har rapporterats.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vi har då funnit att två viktiga klasser av neurotransmittorreceptorer (glutamat- och acetylkolinreceptorer) inducerar förlust av ER från spines och att denna dynamik är ändrad i en musmodell av Alzheimers sjukdom. Vidare har vi visat att aktivering av de här två receptortyperna också aktiverar en process som kallas store operated calcium entry (SOCE) och syftar till att bibehålla ER:s kalciumnivåer. Precis som andra forskargrupper har vi funnit att SOCE är minskad i nervceller från alzheimermöss. Däremot är själva induktionssteget för SOCE normalt och felaktigheterna som kopplats till Alzheimers sjukdom måste alltså bero på ett senare steg.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har vi alltså upptäckt cellulära mekanismer som med stor sannolikhet är viktiga för hur vi lär oss och bildar minnen. Mycket talar också för att de här mekanismerna är påverkade hos patienter med Alzheimers sjukdom. Genom ytterligare studier av de här nyupptäckta mekanismerna ökar möjligheten att finna ett sätt att lindra eller helt avbryta sjukdomsförloppet.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b2ed0317-3ba3-4bfc-8ab7-e54e9c4746eb</url> </location> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Endoplasmic reticulum</topic> <topic>primary culture</topic> <topic>dendritic spines</topic> <topic>live cell imaging</topic> <topic>STIM1</topic> <topic>carbachol</topic> <topic>store-operated calcium entry</topic> <topic>3</topic> <topic>familial Alzheimer&apos;s disease</topic> <topic>5-dihyroxyphenyglycine</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86443-93-1</identifier> <identifier type="oldLupId">1607510</identifier> <part> <detail type="volume"> <number>2010:77</number> </detail> <extent unit="pages"> <total>140</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-06-19T09:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The Myrin can be used in clinical routine work and the Zebris® adds information about 3-dimensional movements. (Study I).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Cervical range of motion was examined in three dimensions in 120 neck-healthy subjects. Movement patterns of combined primary and coupled movements and the influence of age, gender and body mass index on these movements were investigated. &lt;br/&gt;&lt;br&gt; Coupled movements are a natural part of cervical motion together with primary movements. Age affects the majority of primary and coupled cervical movements; the coupled movements of primary rotation and lateral flexion are especially changed with age (Study II).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Twenty-two patients with dizziness of suspected cervical origin were examined with a structured physical examination and carefully examined to exclude other causes of dizziness. The effects of physiotherapy, based on these musculoskeletal findings, were evaluated directly after treatment and again long-term with questionnaires.&lt;br/&gt;&lt;br&gt; Patients with suspected cervicogenic dizziness had some musculoskeletal findings in common, e.g., tenderness and tightness in the dorsal neck muscles, preserved cervical mobility and reduced cervico-thoracic mobility. Treatment based on these findings reduced both neck pain and dizziness. Some patients seem to need a maintenance strategy to avoid relapses in the long-term (Study III).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Twenty neck-healthy subjects were examined before and after a unilateral neck muscle fatiguing task with head repositioning tests.&lt;br/&gt;&lt;br&gt; An average overshoot before the fatiguing task decreased after acute muscle fatigue and the increased accuracy was significant and most pronounced for movements directed towards the fatigued side (Study IV).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Eleven subjects with bilateral vestibulopathy were compared to fifteen healthy subjects in their ability to reproduce different head on trunk target positions. &lt;br/&gt;&lt;br&gt; The subjects with bilateral vestibulopathy maintained their ability to recognize and fine-tune head on trunk movements (Study V).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Cervical movement performance changed with increasing age. Treatment of cervical musculoskeletal findings reduced both neck pain symptoms and dizziness; diagnosis ex juvantibus supports the diagnosis of cervicogenic dizziness. Cervical proprioception is an important factor in sensing head on trunk movements.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Lund University, Faculty of Medicine Doctoral Dissertation Series 2008:52</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Känselinformation (sensorisk information) från nacken har stor betydelse för rumsorienteringen. För att kunna detektera kroppsrörelser korrekt och därigenom bibehålla balansen krävs ett samspel mellan nackens sensoriska information tillsammans med kroppens övriga led- och muskelsinnen (proprioceptionen), balansapparaterna i inneröronen (vestibularisorganen), synen samt känselreceptorerna i huden. Vestibularisorganen känner av huvudrörelser och huvudets position i förhållande till tyngdkraften. Synen informerar om hur omvärlden rör sig i förhållande till huvudet och hur huvudet rör sig i rummet. Eftersom sinnesorganen för både balans och syn är belägna i skallbasen är det av stor vikt att få information om hur huvudet rör sig i förhållande till resten av kroppen. Nackens sensoriska information har i detta sammanhang stor betydelse, vilket bland annat det faktum att ett stort antal känselreceptorer finns i nackens muskler och leder talar för.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Om informationen från de olika sensoriska organen inte stämmer överens, d.v.s. att det finns en sensorisk konflikt, kan det ge upphov till yrsel. Ett exempel på en sensorisk konflikt är sjösjuka då synen inte ger någon information om den faktiska rörelsen, eftersom omgivningen (båtens däck) gungar likadant som huvudet i övrigt, samtidigt som kroppens övriga känselorgan och framför allt vestibularisorganen uppfattar att båten gungar. En störning i informationen från nackens muskulatur och leder skulle kunna orsaka en liknande sensorisk konflikt ställt mot det sensoriska inflödet från vestibularisorganen och synen och således teoretiskt ge upphov till ’nackutlöst yrsel’. Både yrsel och besvär från nacken är vanligt förekommande varför det inte är självklart att symtomen har ett samband, även om patienter har båda symtomen samtidigt. Eftersom det dessutom saknas kliniska tester och klara kriterier för nackutlöst yrsel är diagnosen fortfarande kontroversiell. Nackutlöst yrsel kan endast bekräftas när andra orsaker till yrseln kan uteslutas och kanske alldeles säkrast när patienten blir symtomfri efter behandling av nackbesvären. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ökad kunskap om nackens betydelse för balans och orienteringsförmåga skulle kunna förklara och stärka dess betydelse som en utlösande faktor för yrsel samt öka kunskapen om nackens betydelse när andra sensoriska inflöden fallerar. Dessa reflektioner står som bas för avhandlingen. Ett sätt att pröva nackens proprioceptiva betydelse för orienteringsförmågan är att trötta ut nackens muskulatur och därefter undersöka förmågan att återta i förväg specificerade målpositioner av huvudet relativt mot bålen. Ett annat sätt är att undersöka precisionen av huvudrörelser hos patienter som förlorat funktionen av de vestibulära organen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att studera nackens funktion behöver man kunna mäta dess rörelseförmåga med metodmässig stor säkerhet. I studie 1 undersöktes detta hos frivilliga försökspersoner genom rörelsemätning med Myrin (inklinometer/kompassmetod, en manuell metod som ofta används i klinisk verksamhet) samtidigt med Zebris (tredimensionell ultraljudsbaserad rörelseanalys). En grundläggande skillnad mellan metoderna är att Zebris registrerar huvudets rörelser relativt bålen, medan Myrin mäter huvudets rörelser i förhållande till tyngdkraften och jordens magnetfält. Metoderna visade sig vara väl jämförbara, även om Zebris var något mer tillförlitlig och registrerade ett något större rörlighetsutslag. Detta beror troligen på att förmågan att detektera det absolut största rörelseutslaget är mer känsligt hos Zebris jämfört med Myrin som avläses manuellt. Sammantaget ger Zebris större möjligheter att registrera rörelser i tre dimensioner, vilket gör det möjligt att utföra analyser av nackens kombinerade rörelsemönster.&lt;br/&gt;&lt;br&gt; I studie 2 undersöktes nackens tredimensionella rörelsemönster vid maximalt rörelseuttag hos frivilliga försökspersoner i olika åldrar. Resultaten visade att nackrörelser ofta är kombinerade. Rörelser som var tänkta att utföras i frontalplanet (örat mot axeln) skedde oftast i kombination med kopplade rörelser i horisontalplanet (nackvridning), medan rörelser som var tänkta att utföras i horisontalplanet oftast kombinerades med kopplade rörelser i sagittalplanet (framåt-bakåt). Dessutom kunde det visas att vissa kopplade rörelser ändrar riktning hos äldre försökspersoner, vilket troligen kan förklaras av en ändrad förläggning av rörelserna i nackkotpelaren samt av en förändrad kroppshållning. &lt;br/&gt;&lt;br&gt; I studie 3 undersöktes nackens muskler, rörlighet i nacke och bröstrygg, hållning och stabilitet hos en grupp av patienter, som misstänktes ha nackutlöst yrsel. Patienterna uppvisade stor rörlighet i nacken, närmast överrörlighet hos en del patienter. Dessutom hade de både muskulär ömhet och stramhet i de bakre nackmusklerna. Ihopsjunken hållning och stelhet i övergången mellan nacke och bröstrygg var också vanligt. Patienterna behandlades med riktade åtgärder mot de olika fynden och behandlingens effekt på studieparametrarna utvärderades direkt efter behandlingens avslut. Den bestående effekten av behandlingen på patienternas subjektiva nackbesvär samt yrselupplevande utvärderades långsiktigt. Patienterna var förbättrade direkt efter avslutad behandling och vid uppföljning efter 6 månader och 2 år var besvären från nacken samt yrseln fortfarande lindrigare. Eftersom både patienternas nackbesvär och yrsel förbättrades av behandling som riktades mot nackbesvären, stärks misstanken om att yrseln var nackutlöst. &lt;br/&gt;&lt;br&gt; För att undersöka vilken komponent i nackbesvären som kan bidra till nackutlöst yrsel undersöktes i studie 4 hur muskeluttröttning påverkar orienteringsförmågan. Friska försökspersoner fick trötta ut ena sidans nackmuskler genom att belasta nackmusklerna med 30 % av sin maximala kraft under 5 minuter. En förstudie där musklernas aktivering mättes med EMG (elektromyografi − registrering av de elektriska spänningsförändringar som muskelcellerna genererar) bekräftade att det bara var den ena sidan av nacken som engagerades under belastningen. Efter uttröttningen förändrades och förbättrades förmågan att hitta tillbaka till en tidigare introducerad målposition, visat genom att en tidigare tendens att gå förbi målet minskade efter uttröttningen. Resultaten tyder på att muskelsinnet, proprioceptionen, blir mer känsligt för att korrekt rapportera rörelser efter en akut tillfällig uttröttning. &lt;br/&gt;&lt;br&gt; I studie 5 undersöktes betydelsen av nackens proprioception ytterligare genom att analysera orienteringsförmågan av huvudet relativt bålen hos en grupp patienter som förlorat funktionen i båda sidors vestibularisorgan jämfört med en kontrollgrupp med friska frivilliga personer. Patientgruppen skilde sig inte mot kontrollgruppen när det gäller förmågan att med nackvridning återta olika målpositioner av huvudets läge. Fyndet talar för att nackens proprioception kan ge tillräcklig information vid långsamma huvudrörelser så att förlusten av den vestibulära funktionen helt kan uppvägas. Detta stärker antagandet om att nackens proprioceptiva roll är betydelsefull för orienteringsförmågan.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammantaget bekräftar studierna att rörligheten i nacken och dess proprioception är av stor betydelse för orienteringsförmågan. Resultaten indikerar tillsammans med de positiva behandlingsresultaten vid förmodad nackutlöst yrsel att det kan finnas ett samband mellan nackbesvär och yrselupplevande.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/837e19c0-feaa-425b-88ff-8e97e4b9f7d7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Malmstrom_Cervical_influence_on_dizziness_and_orientation.pdf">https://portal.research.lu.se/files/3399909/1059806.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1483514</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Health Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Neck pain</topic> <topic>Muscle fatigue</topic> <topic>Vestibular diseases</topic> <topic>Cervical range of motion</topic> <topic>Cervical spine</topic> <topic>3-D movement analysis</topic> <topic>Dizziness</topic> <topic>Proprioception</topic> <topic>Primary and coupled movements</topic> <topic>Physiotherapy</topic> </subject> <subject authority="lup"> <topic>Oto-rhino-laryngology</topic> <topic>Physiotherapy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-05-7</identifier> <identifier type="oldLupId">1059805</identifier> <part> <detail type="volume"> <number>2008:52</number> </detail> <extent unit="pages"> <total>55</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-05-17T09:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The aim of this thesis was to determine the role of isoprenylation (farnesyltransferase and geranylgeranyltransferase) as well as NET formation in regulating recruitment of neutrophils and tissue damage in severe AP. &lt;br/&gt;&lt;br&gt; AP in mice was induced by retrograde infusion of Na-taurocholate into the pancreatic duct and intraperitoneal injection of L-arginine two times at hourly intervals. Induction of pancreatitis provoked a clear cut increase in tissue damage of the pancreas characterized by neutrophil infiltration, myeloperoxidase activity, chemokine levels, and acinar cell necrosis and edema formation in the pancreas. In paper I, farnesyltransferase mediates leukocyte sequestration and tissue injury in AP. Inhibition of farnesyltransferase attenuates infiltration of neutrophils in the pancreas and the lung and suggesting that farnesyltransferase controls both local and systemic inflammation in pancreatitis. Paper II demonstrates that geranylgeranyltransferase regulate severity in pancreatitis. Inhibition of geranylgeranyltransferase results in a reduction of neutrophil up-regulation Mac-1 and CXCL2 formation in the pancreas. Blocking geranylgeranyltransferase activity attenuated systemic inflammation and pulmonary neutrophils in animals with pancreatitis. In paper Paper III address the role of Ras-signalling in AP. Ras inhibition improves neutrophil infiltration, blood amylase, cytokine formation and and pancreatitis-associated systemic inflammation. Paper IV demonstrates that NETs are generated in the inflamed pancreas and play a critical role in the development of severe AP. Inhibition of NET decreased CXCL2 formation and neutrophil recruitment in the inflamed pancreas. Moreover, NETs regulates STAT3 activity and trypsin activation in acinar cells and histones might be important molecular mediators in these processes. &lt;br/&gt;&lt;br&gt; These findings identify a novel role of isoprenylation and NET formation in pancreatitis and suggest that targeting these mechanisms might be a useful way to ameliorate local and systemic inflammation in severe AP.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/62fd0581-34ab-4556-ae04-b227f666674b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Mohammed_Merza_THESIS-1.pdf">https://portal.research.lu.se/files/3400021/5275161.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9230263</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Acute pancreatitis</topic> <topic>neutrophil recruitment</topic> <topic>trypsinogen activation</topic> <topic>NET</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-117-0</identifier> <identifier type="oldLupId">5268341</identifier> <part> <detail type="volume"> <number>2015:38</number> </detail> <extent unit="pages"> <total>170</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-04-23T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>62fd0581-34ab-4556-ae04-b227f666674b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:12+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:12+02:00</recordDateApproved> </recordInfo> </mods>

Most companies have a formal incident learning system and considerable resources are used for reporting incidents and for utilising these experiences to prevent future incidents. However, there are many indications that only a portion of the entire potential for learning from reported incidents is actually utilised. In order to know whether this apprehension is correct and to be able to manage and improve the situation, if necessary, one would need to have a methodology for assessing the learning in such systems. Therefore, the author has undertaken to develop a methodology for this, which is presented in the thesis. The methodology could be used on a wide variety of incident learning systems and by people in the process industry, in authorities and by researchers, with the general aim to improve learning from incidents.&lt;br/&gt;&lt;br&gt; Several aspects of learning need to be included in a methodology for a comprehensive assessment of how effectively the learning from incidents works. One has to be able to address the following types of issues:&lt;br/&gt;&lt;br&gt; 1. Do we handle the incidents reported in our incident learning system properly? Do the various steps in the learning cycle work effectively?&lt;br/&gt;&lt;br&gt; 2. How much do we learn from the incidents which are reported? How does this learning compare with what could potentially have been extracted? What level of learning are we at and what level could we have achieved?&lt;br/&gt;&lt;br&gt; 3. Do we report the incidents that are worth reporting (that have a learning potential)? What is the threshold for reporting? How big is the number of unreported cases, the “hidden number”? &lt;br/&gt;&lt;br&gt; In order to address issue 1, a method has been developed which assesses the effectiveness of learning in every step of the learning cycle (Reporting – Analysis – Decision – Implementation – Follow-up) for each incident, and of the aggregated material of many incidents. The method contains a tool for each step, built on a number of dimensions which in turn contain a number of aspects. By using a rating system including a scale with formulated requirements for some levels, the effectiveness of each step can be assessed numerically for each individual incident. &lt;br/&gt;&lt;br&gt; For issue 2, a method has also been developed that builds on classifying the learning product, the measures taken, in different levels depending on how well the experiences from an incident are handled. The basis for classifying an incident is the geographical application, the degree of organisational learning, and the duration of the measures taken. Incidents are classified both in actual levels of learning based on the measures taken, and in potential levels of learning, indicating the level that could have been achieved if all the potential for learning had been utilised. The relation (the ratio) between actual and potential levels of learning is a measure of the effectiveness of the learning. A specific method for evaluating the underlying causation has been developed to draw conclusions about the potential learning. &lt;br/&gt;&lt;br&gt; For issue 3, a tool has been developed for assessing the threshold for reporting as well as guidelines for what can be considered reasonable frequencies of incident reporting in the process industry. In addition to providing information about how efficient the reporting of incidents is, this will also provide input to the method for issue 2. &lt;br/&gt;&lt;br&gt; Together, the methods with their tools and guidelines constitute a methodology, which allows the user to make a total assessment of the effectiveness of the learning from incidents in process industry companies.&lt;br/&gt;&lt;br&gt; The empirical material for the research was taken from the incident databases of six Swedish process industry companies, and from the EC MARS database for major accidents in enterprises which fall under the Seveso legislation. &lt;br/&gt;&lt;br&gt; The results from the application of the methods have proven that learning from incidents is often limited, especially in relation to what would have been possible to achieve. Effectiveness in the learning cycle is often relatively poor, especially in the analysis and the follow-up steps. &lt;br/&gt;&lt;br&gt; The results from the assessment of the learning effectiveness combined with the results from safety audits often offer valuable insight into the decisive factors for good learning.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Stora resurser används i processindustrin, och i många andra industribranscher, på att&lt;br/&gt;&lt;br&gt; rapportera incidenter för att utnyttja erfarenheterna från dessa för att förebygga&lt;br/&gt;&lt;br&gt; framtida incidenter – alltifrån mindre störningar till olyckor med stora konsekvenser.&lt;br/&gt;&lt;br&gt; Det finns emellertid en hel del som tyder på att man ofta utnyttjar bara en del av hela&lt;br/&gt;&lt;br&gt; den potential för lärande som finns i de incidenter som rapporteras. Flera källor i den&lt;br/&gt;&lt;br&gt; vetenskapliga litteraturen vittnar om detta. Författaren, som tillbringat fyrtio år i&lt;br/&gt;&lt;br&gt; processindustrin har en hel del erfarenheter som pekar på samma sak. För att skapa en&lt;br/&gt;&lt;br&gt; grund för att förbättra denna situation måste man ha en klar och välgrundad&lt;br/&gt;&lt;br&gt; uppfattning om hur tillståndet kring lärandet från incidenter är i en organisation.&lt;br/&gt;&lt;br&gt; Man behöver kunna utvärdera effektiviteten i lärandet för att kunna styra och leda det&lt;br/&gt;&lt;br&gt; mot förbättringar.&lt;br/&gt;&lt;br&gt; Författaren har inte funnit några bra metoder för sådana utvärderingar, varken i den&lt;br/&gt;&lt;br&gt; vetenskapliga litteraturen eller i mer erfarenhetsmässigt baserade applikationer ute&lt;br/&gt;&lt;br&gt; bland företag. Ett starkt behov av att utveckla en metodik, inklusive specifika metoder&lt;br/&gt;&lt;br&gt; och verktyg, för att kunna utvärdera effektiviteten i lärandet från incidenter har alltså&lt;br/&gt;&lt;br&gt; identifierats. Detta faktum var utgångspunkten för det forskningsarbete som&lt;br/&gt;&lt;br&gt; presenteras i denna avhandling. En metodik för att utvärdera effektiviteten i lärandet&lt;br/&gt;&lt;br&gt; från incidenter har tagits fram.&lt;br/&gt;&lt;br&gt; Forskningen är baserad på information om incidenter, som finns samlad i databaser&lt;br/&gt;&lt;br&gt; som täcker en längre tidsperiod (år). De flesta processindustriföretag har idag sådana&lt;br/&gt;&lt;br&gt; databaser för hantering av incidenter, från rapportering till formellt avslut av ärendet,&lt;br/&gt;&lt;br&gt; för ett brett spektrum av incidenter. Även en databas (MARS), administrerad av&lt;br/&gt;&lt;br&gt; Europakommissionen, för stora olyckor med allvarliga konsekvenser har utgjort&lt;br/&gt;&lt;br&gt; material för forskningsarbetet.&lt;br/&gt;&lt;br&gt; För att kunna göra en allomfattande bedömning av hur effektivt lärandet fungerar i&lt;br/&gt;&lt;br&gt; ett processindustriföretag har utgåtts från att flera aspekter i lärandet måste ingå i en&lt;br/&gt;&lt;br&gt; sådan metodik. Man måste kunna få svar på följande typer av frågeställningar:&lt;br/&gt;&lt;br&gt; 1. Har vi en effektiv hantering av de incidenter som rapporteras i vårt&lt;br/&gt;&lt;br&gt; system? Fungerar de olika stegen i lärcykeln effektivt?&lt;br/&gt;&lt;br&gt; 2. Hur mycket lär vi oss av de incidenter som rapporteras i förhållande till&lt;br/&gt;&lt;br&gt; vad som potentiellt går att lära sig av dem? Vilken lärandenivå ligger vi&lt;br/&gt;&lt;br&gt; på och vilken skulle vi kunna ligga på?&lt;br/&gt;&lt;br&gt; 3. Rapporterar vi de incidenter som är värda att rapportera? Vad är tröskeln&lt;br/&gt;&lt;br&gt; för rapportering? Hur stort är mörkertalet?&lt;br/&gt;&lt;br&gt; Framför allt måste i en sådan metodik ingå effektiviteten både i processen för lärande&lt;br/&gt;&lt;br&gt; och av produkten av lärandet, de två klassiska delarna i teorin kring lärande. Som en&lt;br/&gt;&lt;br&gt; tredje och självständig aspekt i att få en heltäckande utvärdering av hur lärandet&lt;br/&gt;&lt;br&gt; VIII&lt;br/&gt;&lt;br&gt; fungerar måste också behandlas frågan om i vilken utsträckning rapportering sker av&lt;br/&gt;&lt;br&gt; de incidenter som är värda att rapportera.&lt;br/&gt;&lt;br&gt; För att kunna ge svar på frågeställning 1 ovan har utvecklats en metod som värderar&lt;br/&gt;&lt;br&gt; effektiviteten i varje steg i vad som här benämns lärcykeln (Rapportering – Analys –&lt;br/&gt;&lt;br&gt; Beslut – Implementering – Uppföljning) för varje enskild incident och dessutom av&lt;br/&gt;&lt;br&gt; ett samlat material av många incidenter. Metoden innehåller verktyg för varje steg,&lt;br/&gt;&lt;br&gt; som bygger på ett antal dimensioner, som i sin tur innehåller ett antal aspekter. Med&lt;br/&gt;&lt;br&gt; hjälp av en konstruerad bedömningsskala med formulerade krav för ett antal nivåer&lt;br/&gt;&lt;br&gt; kan effektiviteten i varje steg bedömas med ett numeriskt värde för varje enskild&lt;br/&gt;&lt;br&gt; incident.&lt;br/&gt;&lt;br&gt; För frågeställning 2 ovan har också utvecklats en metod, som bygger på att klassificera&lt;br/&gt;&lt;br&gt; lärandeprodukten, de genomförda åtgärderna, i olika nivåer beroende på hur väl&lt;br/&gt;&lt;br&gt; erfarenheterna från en incident används. Grunden för att klassificera en incident är&lt;br/&gt;&lt;br&gt; den geografiska appliceringen, graden av organisatoriskt lärande samt tidsaspekten av&lt;br/&gt;&lt;br&gt; de vidtagna åtgärderna. Dels klassificeras en incident i lärandenivå utifrån de faktiskt&lt;br/&gt;&lt;br&gt; vidtagna åtgärderna, dels görs en utvärdering av vilken lärandenivå som varit möjlig&lt;br/&gt;&lt;br&gt; om hela potentialen för lärande utnyttjats. Förhållandet mellan verklig och potentiell&lt;br/&gt;&lt;br&gt; lärandenivå blir ett mått på effektiviteten av lärandet. Ett särskilt verktyg för att&lt;br/&gt;&lt;br&gt; utvärdera den underliggande orsaksbilden har utvecklats för att ur denna kunna dra&lt;br/&gt;&lt;br&gt; slutsatser om det potentiella lärandet. I metoden ingår också att kunna ta hänsyn till&lt;br/&gt;&lt;br&gt; att det oftast finns ett mörkertal av ej rapporterade, men rapportervärda, incidenter,&lt;br/&gt;&lt;br&gt; samt ta hänsyn till eventuellt lärande från ett samlat material av incidenter och även&lt;br/&gt;&lt;br&gt; till eventuellt lärande genom andra sätt än via incidenthanteringssystemet.&lt;br/&gt;&lt;br&gt; För frågeställning 3 ovan har utvecklats ett verktyg för att bedöma tröskeln för&lt;br/&gt;&lt;br&gt; rapportering, samt riktlinjer för vad som kan vara rimliga rapporteringsfrekvenser av&lt;br/&gt;&lt;br&gt; incidenter i processindustrin. Förutom att ge information i sig om hur effektiv&lt;br/&gt;&lt;br&gt; rapporteringen av incidenter är, ger dessa verktyg viss input till metoden för&lt;br/&gt;&lt;br&gt; frågeställning 2.&lt;br/&gt;&lt;br&gt; I forskningen på MARS-databasen har arbetet begränsats till att omfatta frågeställning&lt;br/&gt;&lt;br&gt; 2.&lt;br/&gt;&lt;br&gt; Tillsammans utgör metoderna med sina verktyg och riktlinjer en metodik, som&lt;br/&gt;&lt;br&gt; tillåter användaren att göra en utvärdering av effektiviteten i lärandet från incidenter&lt;br/&gt;&lt;br&gt; för företag inom processindustrin.&lt;br/&gt;&lt;br&gt; Empirin för forskningen har varit dels material från incidentdatabaser från sex svenska&lt;br/&gt;&lt;br&gt; processindustriföretag, dels Europakommissionens databas (MARS) för stora olyckor i&lt;br/&gt;&lt;br&gt; verksamheter som faller under Seveso-lagstiftningen. I tillägg har författaren använt&lt;br/&gt;&lt;br&gt; en hel del domänkunskaper som förvärvats under egen verksamhet inom&lt;br/&gt;&lt;br&gt; processindustrin under många år.&lt;br/&gt;&lt;br&gt; IX&lt;br/&gt;&lt;br&gt; Forskningsmetodiken har huvudsakligen byggt på metoder inom designvetenskap och&lt;br/&gt;&lt;br&gt; i någon mån case-study-teknik. Efter att ha etablerat en allmän kunskapsbas samt&lt;br/&gt;&lt;br&gt; formulerat specifika mål för forskningen har arbetssättet bestått av att utveckla&lt;br/&gt;&lt;br&gt; metoder, testa dessa metoder och slutligen utvärdera och modifiera metoderna.&lt;br/&gt;&lt;br&gt; Validiteten av metoderna och verktygen har prövats framför allt genom&lt;br/&gt;&lt;br&gt; expertutlåtanden och genom omdömen från de företag som deltagit i forskningen,&lt;br/&gt;&lt;br&gt; med gott resultat.&lt;br/&gt;&lt;br&gt; Metoderna och verktygen har vid användning på det empiriska underlaget visat sig&lt;br/&gt;&lt;br&gt; fungera mycket väl och givit stabila resultat.&lt;br/&gt;&lt;br&gt; Resultaten från användning av metoderna har bekräftat att lärandet från incidenter&lt;br/&gt;&lt;br&gt; ofta är begränsat, särskilt i förhållande till vad som hade varit möjligt att uppnå.&lt;br/&gt;&lt;br&gt; Effektiviteten i lärcykeln är ofta också relativt svag, särskilt i analyssteget och i&lt;br/&gt;&lt;br&gt; uppföljningssteget. Stora variationer förekommer dock mellan olika företag som&lt;br/&gt;&lt;br&gt; deltagit i forskningsstudien. Resultaten från bedömning av effektiviteten av lärandet&lt;br/&gt;&lt;br&gt; kombinerat med resultaten av säkerhetsrevisioner ger ofta god insyn i vad som är&lt;br/&gt;&lt;br&gt; avgörande faktorer för att nå bra lärande.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis kan konstateras att forskningen som redovisas i denna&lt;br/&gt;&lt;br&gt; avhandling har genererat en metodik som innehåller ett antal metoder och verktyg&lt;br/&gt;&lt;br&gt; som på ett kraftfullt sätt kan användas för att bedöma effektiviteten i ett&lt;br/&gt;&lt;br&gt; processindustriföretags sätt att hantera incidenter. Resultaten från användningen av&lt;br/&gt;&lt;br&gt; denna metodik kan användas för att avgöra var svaga punkter finns och därmed var&lt;br/&gt;&lt;br&gt; utrymme för förbättringar finns. Eftersom metoderna genererar numeriska resultat&lt;br/&gt;&lt;br&gt; kan metoderna också med fördel användas i forskningsarbete där man är intresserad&lt;br/&gt;&lt;br&gt; av att finna korrelationer mellan lärandet från incidenter och andra system eller&lt;br/&gt;&lt;br&gt; företeelser för säkerhet, vilka kan uttryckas numeriskt. Metodiken är avsedd att&lt;br/&gt;&lt;br&gt; användas av personer med en ganska bred bakgrund i säkerhetsfrågor.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9b42612f-cacf-4ed7-8aee-ff7aa27d5b17</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Anders_J_G5_15778_2.pdf">https://portal.research.lu.se/files/3400233/1939964.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1298077</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University/EAT</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Accidents</topic> <topic>Incidents</topic> <topic>Learning from incidents</topic> <topic>Learning cycle</topic> <topic>Lesson learned</topic> <topic>Process industry</topic> </subject> <subject authority="lup"> <topic>Engineering and Technology</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-128-6</identifier> <identifier type="oldLupId">1939961</identifier> <part> <extent unit="pages"> <total>141</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-06-01T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>9b42612f-cacf-4ed7-8aee-ff7aa27d5b17</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:14+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:14+02:00</recordDateApproved> </recordInfo> </mods>

Peripheral vaccination with irradiated tumor cells represent a novel therapy that targets both dividing and non-dividing tumor cells and minimizes the risk of therapy resistance by presenting multiple tumor antigens. &lt;br/&gt;&lt;br&gt; In this doctoral thesis, we report enhanced cure of rats and mice with malignant brain tumors after peripheral immunizations with irradiated tumor cells, either unmodified or transduced to produce the immunostimulatory cytokines interferon-γ (IFN-γ) or granulocyte macrophage-colony stimulating factor. The preclinical studies demonstrate that immunotherapy is further enhanced by simultaneous administration of the selective cyclooxygenase-2 (COX-2) inhibitors parecoxib and valdecoxib. Increased amounts of IFN-γ and proliferating T cells in blood corresponded with the induced immune responses and the T cells were committed to the T helper 1 (Th1) lineage, indicating that immunotherapy and COX-2 inhibition induces a strong anti-tumor Th1 response. Finally, immunotherapy and COX-2 inhibition protected against secondary tumors and the memory response was associated with systemic and intratumoral presence of CD8+ T cells, thereby further strengthening the Th1 response. &lt;br/&gt;&lt;br&gt; Prostaglandin E2 (PGE2) was also present in tumor cultures and plasma samples of patients with malignant brain tumors (GBMs, medulloblastomas and ependymoma). Furthermore, plasma PGE2high, IFN-γhigh and interleukin-10low corresponded with prolonged survival in GBM patients following peripheral IFN-γ immunotherapy, implying that the combination of these cytokines can be used to detect an ongoing anti-tumor immune response and consequently predict the therapeutic outcome.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, the combination of immunotherapy and COX-2 inhibition induce cure in experimental brain tumor models and blood cytokines and PGE2 define an ongoing anti-tumor response, as determined in both animals and humans.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8125d4d7-4cc0-413e-9e87-b4de0cf7dedf</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Malignant brain tumors</topic> <topic>immunotherapy</topic> <topic>IFN-γ</topic> <topic>GM-CSF</topic> <topic>COX-2 inhibition</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-21-0</identifier> <identifier type="oldLupId">2972221</identifier> <part> <detail type="volume"> <number>2012:58</number> </detail> <extent unit="pages"> <total>71</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-09-08T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>8125d4d7-4cc0-413e-9e87-b4de0cf7dedf</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:19+02:00</recordDateApproved> </recordInfo> </mods>

This is either because of missing insulin production due to failure of the β-cells in the pancreas (Type 1) or because of reduced sensitivity of the cells in the body to insulin (Type 2). The therapy for Type 1 diabetic patients usually consists of insulin injections to substitute for the missing insulin. The decision about the amount of insulin to be taken has to be made by the patient, based on empirically developed rules of thumb. To help the patient with this task, advanced mathematical algorithms were used in this thesis to determine intakes of insulin and counteracting glucose that can bring the blood glucose concentration back to normoglycemia. The focus in this work was to determine insulin and glucose intakes around mealtimes. These algorithms used optimization methods together with predictions of the blood glucose concentration and mathematical models describing the patient dynamics to determine the insulin and glucose doses. For evaluation, the control algorithms were tested insilico using a virtual patient and are compared to a simple bolus calculator from the literature. The aim was to increase the time spent in the safe range of blood glucose values of 70 − 180 [mg/dL].</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/3b3ef998-234f-4780-ab14-698c83ed2cb8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Meike_Stemmann_Licencitate_3.pdf">https://portal.research.lu.se/files/3400863/3567706.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">843380</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Control</topic> <topic>Diabetes</topic> <topic>Prediction</topic> <topic>Optimization</topic> <topic>Decision Support System</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Research Reports TFRT-3258</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">3567702</identifier> <part> <extent unit="pages"> <total>98</total> </extent> </part> </relatedItem> <note type="additionalInfo">key=stemmann2013lic month=march</note> <recordInfo> <recordIdentifier>3b3ef998-234f-4780-ab14-698c83ed2cb8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:20+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-23T10:04:28Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:20+02:00</recordDateApproved> </recordInfo> </mods>

The main reason why the D-part is often disabled in industrial control loops is because it leads to control signal sensitivity of measurement noise. A frequently varying control signal with too high amplitude will very likely lead to actuator wear and tear. For this reason it is extremely important for any PID design method to take this into account.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The proposed controllers are derived using a newly developed design software that solves an IAE minimization problem with respect to H∞ robustness constraints on the sensitivity- and complementary sensitivity function. The software is shown to be fast, easy to use and robust in giving well-performing controllers.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; By extracting measurement noise from the process value of a real plant, one can estimate its effect on the control signal variance. The time constant of the low-pass filter, through which measurements are fed, is varied to design controllers with constrained control signal activity. By comparing control signal variance and IAE, the user is also able to weigh actuator wear to estimated performance.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The proposed PID design method has shown to give very promising results both on simulated examples and real plants such as a recirculation flow process.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Optimal Youla parametrized controllers are used both as a quality check of the designed PI and PID controllers and as a tool for determining when these are valid choices compared to more advanced controllers.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/57ee172c-3af8-40f9-9973-8a21df7c7de7</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="gar09lic.pdf">https://portal.research.lu.se/files/3401075/8146224.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2700877</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>measurement noise</topic> <topic>constrained control signal activity</topic> <topic>linear systems</topic> <topic>disturbance rejection</topic> <topic>PID control</topic> <topic>process control</topic> <topic>Youla parameterized controllers</topic> <topic>algorithms and software</topic> </subject> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Research Reports TFRT-3245</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">1624916</identifier> <part> </part> </relatedItem> <recordInfo> <recordIdentifier>57ee172c-3af8-40f9-9973-8a21df7c7de7</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:23+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-23T14:13:52Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:23+02:00</recordDateApproved> </recordInfo> </mods>

Over the past decades there has been a rapid development in understanding and modeling different computer vision applications. Even though much work has been devoted to modelling different problems, less work has been spent on deriving algorithms that solve these problems optimally. Generally one is referred to local search methods such as Newton based method. In this thesis we are interested in developing methods that are guaranteed to find globally optimal solutions. Typically the considered optimization problems are non-convex and may have many local optima.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The thesis can roughly be divided into two parts and two introductory chapters. In the first part, Chapters 3-5, we study various multiple view geometry problems from an optimization point of view. In this setting we typically try to estimate camera positions and orientations and the viewed structure which is represented by 3D points. The estimation is done by minimizing the reprojection error, that is, minimizing the distance between a reprojected 3D point and its corresponding image measurement.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In Chapter 3 we consider the case when the residual errors can be written as affine functions composed with a projection. We refer to this case as affine projective estimation. The residuals of this problem are known to be examples of quasiconvex functions. Since quasiconvexity is preserved under the max operation it is possible to use efficient methods when minimizing the L∞ norm, that is, minimizing the maximal error. In this work we show that they are also pseudoconvex, which is a stronger property and has algorithmic implications. Specifically we show that the KKT conditions are sufficient for a global optimum. We also consider the L2 norm version, that is, least squares estimation. Although the objective function is non-convex, we show that often it is possible to verify that a local minimum is global.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In Chapters 4 and 5 we consider multiview problems which are outside the framework of affine-projective estimation. Firstly we consider problems with outliers and secondly problems with orthogonal constraints. Although these are more difficult we show that in certain cases they can be solved using methods from global optimization.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the second part, Chapters 6-8, we consider cut methods for solving variational problems. In Chapter 6 we consider a continuous counterpart to the well known method of graph cuts. While graph cuts have been observed to favour cuts in directions along the graph edges, continuous cuts produce cuts that are smoother. We extend the continuous framework to include cuts with anisotropic metrics and we show that the concept of α-expansion can be formulated in the continuous framework as well. We derive the same bounds as in the discrete case. In Chapters 7 and 8 we consider energies which are not submodular and hence there are no known polynomial time algorithms for solving these. We present two alternatives to semidefinite programming, based on spectral relaxations. In the final chapter we present a reformulation of the classical normalized cut method for image segmentation. Using this formulation it is possible to incorporate contextual information in the optimization.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/58efa72a-4925-498d-b6df-abc6aba0a70a</url> </location> </relatedItem> <originInfo> <publisher>Centre for Mathematical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Spectral Relaxation</topic> <topic>Normalized Cuts</topic> <topic>Continuous Cuts</topic> <topic>Segmentation</topic> <topic>Generalized Convexity</topic> <topic>3D-Reconstruction</topic> <topic>Global Optimization</topic> <topic>Multiple View Geometry</topic> <topic>Trust Region Subproblem</topic> </subject> <subject authority="lup"> <topic>Computer graphics and computer vision</topic> <topic>Mathematical Sciences</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-628-7784-2</identifier> <identifier type="oldLupId">1392606</identifier> <part> <extent unit="pages"> <total>216</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-05-29T13:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>58efa72a-4925-498d-b6df-abc6aba0a70a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:25+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-13T09:44:19Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:25+02:00</recordDateApproved> </recordInfo> </mods>

Drawing mainly on psychoanalytical and Foucaultian arguments, Butler dwells upon questions concerning power and subjectivity and argues that bodies, in order to gain an intelligible subjectivity, need to assume a certain relationship between sex, gender and desire. Due to the problematic, and sometimes imprecise, differentiation between the concepts of performance and performativity in her theory as well as the somewhat obscure idea of subjectivity, self and corporeality, which Butler’s theorizing implies, this study argues that her theoretical framework can be amended with the help of a social psychological thinking of the subject. Taking its point of departure in an understanding of subjectivity as enabled and maintained through social interaction, social psychology – as presented by George Herbert Mead – provides a framework for understanding subjectivity in terms of self-reflexivity and communication. Making use of the concept of self, Mead argues that interpersonal communication by means of bodily gestures is what makes subjectivity possible and in that sense he comes up with an idea rather similar to Butler’s argument. Hence, both perspectives focuses the societal or discursive contingent nature of subjectivity and locate its achievement in certain forms of doing. The argument pursued in this dissertation revolves around the relationship between the Butlerian notion of subjectivity and the Meadian concept of self and it is argued that an integrative approach towards these perspectives can enhance and further elaborate an understanding of the processes involved in the doing of gender. In this dissertation it is argued that such a perspective provides the foundation of thinking in terms of a queer social psychology.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Attempting to locate intersections, gaps and similarities between these rather disparate theories, the aim of this study is twofold: Firstly, it aims at establishing a theoretical dialogue between Butler and Mead while focusing on their different, yet also similar, approaches to the interrelationship between actors and agency. Secondly, this study aims at deepening this constructed dialogue empirically in order to further elucidate the similarities and differences between Butler and Mead. The main focus here is a comparison of how they conceive of and theorize the conditions and processes through which subjectivity is made possible. Such an approach involves a critical examination of the possibilities to understand gender performativity in terms of a self-reflexive practice as well as providing a framework for further investigation of the relationship between the social self and discursive regulation. In my attempts to combine these theoretical perspectives I focus on the similarities and differences in their specific contributions. Specifically, this means an attempt to focus on Mead’s notion of self and subjectivity as socially accomplished while, at the same time, comparing this view with Butler’s examination of the relationship between gender and subjectivity. This has led me to underscore the importance of reading Butler’s understanding of gender performativity as a social practice, while at the same time pointing towards the necessity in critically relating Mead’s notion of self to questions regarding regulation of the gendered body. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Historically, social psychological attempts to conceptualize the self have neither sufficiently taken into account questions of embodiment and corporeality, nor sufficiently discussed the regulation of gender and sexuality. In the limited number of studies that do take such issues into consideration, the simple fact that the body most often comes dressed is hardly ever discussed. In the social psychological studies that do consider the importance of the dressed body, issues of gender, sexuality and the obligatory character of heterosexuality are often overlooked. This dissertation aims at overcoming these theoretical obstacles through a combination of empirical and theoretical studies. Being empirically grounded in an analysis of cross-dressers’ self-presentations, questions are asked concerning hegemonic obligatory sexuality or the heterosexual matrix, cultural intelligibility and the importance of the dressed body in the materialization of the gendered subject. Broadening conventional social psychological concerns, it is the case that this dissertation establishes a social psychological account of queer theory and an associated understanding of subject formation, while taking the starting point in the concept and phenomenon of cross-dressing. Working with a perspective influenced by queer theory within the field of social psychology is a problematic venture. In order to understand this state of affairs, I make use of cross-dressing as a means of conceptualising the presence of the obligatory heterosexuality as a symbolic structure in the always on-going process of self-formation and in the ways this process relates to such a seemingly simple act as getting and being dressed.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Empirically, the arguments in this dissertation draw upon an analysis of a large number of digital self-presentations and diaries, authored by self-identified male to female cross-dressers between the ages of 15 and 69. In the beginning of 2004, the empirical material was collected from a virtual community (qruiser.com), aimed at serving the Scandinavian homo-/bisexual and transgender population. The material is perceived as containing fragments of the actors’ attempts and strategies for orienting themselves, expressing dreams and perceptions of dress and gender as well as demonstrating how cross-dressing as a social practice relates to other actors, self-perceptions, space and intelligibility. This empirical study is placed in the earlier mentioned attempt to bridge the differences between queer theory and social psychology.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The first part of this dissertation provides a brief overview of different approaches to the relationship between queer theory and social psychology in more general terms, while also illuminating the need to further explore the relationship between Butler and George Herbert Mead, specifically. In contrast to Butler, Mead provides a comprehensive examination of the social processes through which the self is made possible. Arguing that (self-)consciousness (and thus subjectivity) is accomplished socially, Mead’s social psychology proves to have certain similarities with Butler’s theoretical framework. But while Mead situates the emergence of self and subjectivity within the realm of social interaction, he does not take questions regarding the regulation of gendered bodies into account.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; While the first part of this dissertation serves to outline a theoretical framework, the second part consists of an in-depth and comparative reading of Butler and Mead. Introducing and scrutinizing core concepts and lines of reasoning in Butler’s theories of subjectivity, discursive regulation of gender intelligibility and gender performativity, her argumentation is situated in a wider theoretical and political context. The relationship between subjection and subjectivation is examined, leading to an argumentation that her problematic notion of subjectivity as bound up in a discursive web of layers and signs needs to be reconsidered in relation to a social psychological perspective on the dynamic interrelationship between individual and society. While Butler, though implicitly, accentuates the importance of social recognition, this study proposes that the discursive regulation of gender intelligibility needs to be resituated in the realm of social interaction and regarded as bound up in interpersonal relationships. This argument is further developed by exploring Butler’s understanding of the interrelationship between performativity and performance. Understanding gender as a “doing”, it is argued, involves both performativity and performance and thus motivates a further exploration of the possibility of self-reflexive negotiation of gender intelligibility in terms of a social practice.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Turning to a re-examination of Mead, the next chapter explains that his social psychological perspective provides a foundation for understanding agency and subjectivity as resting upon, not a pre-discursive structure but rather a socially conditioned and maintained process of social role-taking. Considering the central issues in his theoretical perspective, Mead’s understanding of the continuously emerging self is further illuminated in the light of his notion of play and game. In this context I argue that an essential link can be found between Mead’s concept of communication with bodily gestures and their development into social acts and Butler’s concept of gender performativity. As Mead conceives that human subjectivity and agency are surfacing through social interaction, I also argue for the necessity to amend his theory with a comprehensive understanding of bodily regulation, as this would help provide an insight into the conditions for role-taking.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In order to deepen the connection between Butler and Mead, while comparing their views on agency and possibility to self-reflexive action, the following chapter puts forward that their understanding of subjection appears to be fundamentally similar. In this chapter it is also suggested that there are some similarities between Mead’s conception of social role-taking as the necessary principle of subjectivity, and Butler’s notion of the relationship between discursive regulation of gender intelligibility and subjectivity. However, whereas Butler sheds light on the regulation of these processes, Mead provides a possibility to understand their position in social practices. Taken together, Butler and Mead offer a foundation for a line of reasoning that takes into account the importance of bodily self-reflexivity in negotiating the boundaries of intelligible gender identity. To further develop this idea and also facilitate a reading of the empirical material presented in chapters six and seven, two concepts are formulated: trans-actor and trans-practice. These concepts serve at providing the cross-dressers with an agency while, at the same time, illuminating the importance of regarding the act of re-dressing the body in a gendered fashion as an explicitly social practice.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The third part of the dissertation turns to my readings of the empirical material. It is first of all demonstrated in what ways cross-dressing can be regarded as a representative example of the Meadian concepts of internal conversation and play. Arguing that cross-dressing to a large extent is a question of self-communicative action involving a drawing of boundaries between femininity and masculinity, this chapter aims at discussing cross-dressing as a means of negotiating gender intelligibility while at the same time locating the objects and actors involved in such a doing. Gradually, the understanding of cross-dressing as a solitary play is moved towards and understanding in terms of a game bound up with certain gender regulating rules. Instead of reading cross-dressing as a deviant form of behaviour, it is understood as a way of doing gender, a negotiation of gender boundaries which at the same time provides a possibility to discuss the regulation of gender in more general terms. Remaining critical to hegemonic heterosexuality, it is possible to enforce the surfacing of a number of important implications for understanding not only cross-dressing as such, but also, and most importantly, mainstream conceptions of gender. Thinking of cross-dressing this way provides a plausible attempt to create a theoretical framework with implications for queer and social psychological inquiry in general. In my readings of the empirical material, numerous conceptions of gender, body and self surface emerge. First of all, it appears that certain ways of acting are believed to be gendered; not that housework (to take one example) ought to be understood as explicitly feminine, but the behaviours in question are regarded as characterizing a specific gender category – as ways of expressing gender, giving it shape and making it plausible. Secondly, performing certain behaviours seems to be constrained by the actor’s bodily appearance. Accomplishing a bodily appearance in line with the cultural regulations of femininity appears to enable or facilitate a behavioural transition from certain gender-specific actions to others. Self-perceptions, bodily appearances and bodily actions appear to be intertwined in different ways, and the putting on of certain gendered clothing seems to enable a perceived temporary transition from one gender to the other. It can be said that the self-presentations provide a whole series of demonstrations of gender as a doing and, simultaneously, illuminating the role of clothing as both enabling and preventing these doings. One of the main concerns in the self-presentations appears to be the experienced ability to re-form the bodily surfaces by means of clothing. Hence, cross-dressing can be regarded as a way of creating a bodily appearance that in the long run contributes to the emergence of not only gestural patterns and bodily attitudes but significantly, it provides the continuously emerging self with altered and stretched boundaries. The self-presentations provide an example of how the complexity, content, form and style of the cross-dressers’ wardrobes play a significant role in the act of cross-dressing. Bodily appearances are altered and a remodelling of the self is accomplished by means of objects and techniques that are thought of as gendered. As a consequence, not only the bodily appearance becomes altered but it also implies a remodelling of the self as such. As a consequence, it is argued that going into the wardrobe facilitates the coming out of the closet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In the fourth and concluding part of the dissertation, general theoretical and empirical topics are put in relation to the dressed body. The conception of dress as determining the boundaries of both self and gender was a recurring theme in the empirical material, and this suggests that it is important to consider the multiplicity of tensions and perceptions involved in the empirical material. I draw the conclusion that certain kinds of gendered clothing appear to materialise a desired transition from masculine to feminine and at the same time negotiating the category boundaries. In that sense, I suggest that it is possible to create an understanding of subjectivities through wardrobes. Wardrobes make a statement of who we are, what gender we have and provide limitations as well as possibilities for human agency. The cross-dressers in the empirical material frequently refer to themselves in terms of clothing and when presenting their cross-dressed selves, the wardrobe – its size and complexity – is used as a significant indicator for indicating change in their gendered self and subjectivity. The cross-dressed self, then, can be regarded as partly located in possessing and using gendered objects since these objects engender the performance of certain gendered behaviours. Understood in this way, intelligible action is bound up with bodily appearance: gendered clothing disciplines bodies; through tying together gestures and bodily appearances, controlling them, excluding them from each other, and fixing them in time and space, making them inextricably inseparable. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Intervening in the fields of social psychology and queer studies, as is done in this dissertation, a demonstration of the multitude of processes involved in doing gender is allowed while at the same time challenging the social psychological understanding of the self. As a result, an understanding of the ways in which actors relate to discourse is established: while negotiating its constraints, re-signifying its foundation and giving its materialised bodies new shapes and meanings through the act of getting dressed in various, yet gendered ways. Thinking of gender this way, gender is regarded as a doing, a performance of gestures and acts that appear to be compulsory and constrained by discursive regulations, but at the same time possible to negotiate through socially mediated self-reflexive practices.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Det övergripande syftet med föreliggande studie är tudelat. För det första syftar den till att på teoretisk väg etablera en dialog mellan queerteoretisk och socialpsykologisk teoribildning om aktörer och aktörsskap med utgångspunkt i en kritisk läsning av Judith Butler och George Herbert Mead. För det andra syftar den till att på empirisk väg utveckla och fördjupa denna dialog i syfte att demonstrera och resonera kring de möjligheter som uppstår i spänningen mellan dessa teoretiska perspektiv. På detta sätt är avsikten att föra ett bidrag till såväl den queer- och genusteoretiska debatten som dess socialpsykologiska motsvarighet. Ambitionen är att detta sammantaget kan utgöra ett ramverk i vilket möjligheterna med en queer socialpsykologi skisseras. I jämförelsen mellan dessa teoretiska perspektiv fokuseras på frågan om hur människor antas bli till som aktörer och under vilka villkor och genom vilka processer detta äger rum. I centrum för denna diskussion positioneras relationen mellan deras respektive antagande om struktur och aktör samt hur denna relaterar till och förutsätts vara uppburen genom något slags praktik. För det andra diskuteras individens möjlighet att omförhandla sitt förvärvade aktörsskap och genom vilka processer och praktiker detta eventuellt kan göras möjligt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Avhandlingen är uppdelad i fyra delar. Den inledande delen (del 1: Inledande ord) introducerar studiens övergripande bakgrund, teoretiska position, syfte, material och de metodologiska överväganden som har gjorts under forskningsresans gång.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den andra delen (del 2: Teoretiska interventioner) utvecklar i tre kapitel den diskussion om spänningen mellan queerteori och socialpsykologi som påbörjades i avhandlingens första och inledande kapitel. I ett första kapitel fokuseras på Judith Butler för att ringa in och granska några centrala argument och faktorer i hennes tänkande. I ett andra kapitel diskuteras George Herbert Mead för att, i likhet med föregående kapitel, presentera hans övergripande argument och huvudsakliga tankegångar. Avslutningsvis avrundas avhandlingens andra del med ett kapitel som syftar till att summera och utveckla den spänningsrelation som hittas mellan dessa två teoretiker samtidigt som en diskussion förs om de möjligheter en empirisk utveckling av den teoretiska problematiken skulle kunna bidra med. Den teoretiska spänning som lokaliseras mellan Mead och Butler kretsar i första hand kring deras förståelse av relationen mellan aktör och praktik och med utgångspunkt i denna formuleras arbetsbegreppen transaktör och transpraktik som genomgående används i presentationen av det empiriska materialet.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Avhandlingens tredje del (del 3: Empiriska nedslag) är i första hand av empirisk karaktär och är uppdelad i två kapitel. I det första av dessa förs en diskussion om hur de självreflexiva genuslekarna inbegriper formulerandet av ett särskilt transgenus och på vad sätt det är möjligt att förstå iscensättandet av genus som en i första hand självkommunikativ praktik. Gradvis demonstreras hur det går att utläsa en önskan om att iscensätta genus tillsammans med andra människor och därför kretsar det följande kapitlet kring en diskussion om betydelsen av social interaktion för detta iscensättande. Med andra ord går det att utläsa en rörelse från självkommunikation till (önskad) social interaktion och detta är ett tema som tydligt ringar in en stor del av den teoretiska problematik som genomsyrar denna studie. I den fjärde och avslutande delen (del 4: Avslutande reflektioner) knyts i tre kapitel de resonemang som hittills har presenterats och diskuterats ihop. Det inledande kapitlet för en teoretiskt orienterad diskussion om den föregående genomgången av det empiriska materialet. I ett därpå följande kapitel fokuseras på olika aspekter av självreflexiva genuslekar i relation till den klädda kroppen för att visa hur den tidigare presenterade praktik- och aktörsproblematiken är avhängig den klädda kroppens genusprägling. I detta sammanhang visas hur det är möjligt att upprätta en relation mellan självets framväxt, subjektivitet och den klädda kroppen. Avslutningsvis förs ett kortfattat resonemang kring avhandlingens huvudsakliga argumentationslinjer och vilka möjligheter ett tänkande inspirerat av queer socialpsykologi för med sig.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/96f3f5d9-872b-429e-98fd-429e417168a0</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="avhandl_mberg.pdf">https://portal.research.lu.se/files/3402560/1044085.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1293179</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>symbolic interactionism</topic> <topic>body</topic> <topic>clothing</topic> <topic>Internet</topic> <topic>dress</topic> <topic>virtual communities</topic> <topic>social psychology</topic> <topic>Queer theory</topic> <topic>Judith Butler</topic> <topic>George H.

Many fragrance substances are volatile and it can therefore be suspected that they may evaporate from petrolatum patch test preparations applied in test chambers. In the first two papers included in this thesis the aims were to i) to investigate the stability of fragrance preparations in petrolatum when applied in patch test chambers, and ii) to investigate the patch test reactivity to samples of fragrance mix I (FM I) and fragrance mix II (FM II) when applied in test cambers 6 days in advance or immediately before the patch test occasion.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Oak moss absolute (OMA), an extract derived from the lichen Evernia prunastri, is a common cause of fragrance contact allergy. OMA contains several allergens, among them atranol and chloroatranol, which have been found to be strong allergens in humans. Therefore, the fragrance industry nowadays provides treated OMAs, where the content of atranol and chloroatranol has been reduced. The aims of studies III and IV in the thesis were to iii) compare the eliciting capacity of treated and untreated OMA samples in patch tests with dilution series and in repeated open application tests (ROATs), and iv) to investigate the reaction pattern in OMA-allergic subjects patch-tested with thin-layer chromatography (TLC) strips of treated and untreated OMA samples.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The findings were as follows: i) The concentrations of 4 of 7 substances investigated decreased by ≥20% within 8 h when stored in Finn chambers at room temperature. The decrease in concentration was slower when the test preparations were stored in a refrigerator. Statistically significantly more reactions were observed for the freshly applied sample of FM I than to the pre-loaded sample, demonstrating that FM I patch test prepared in advance may give false-negative reactions. No corresponding difference was observed for FM II. This is likely explained by differences in volatilities between the ingredients of FM I and FM II. iii) OMA-allergic subjects were statistically significantly less patch test reactive to the treated OMA sample than to the untreated sample. No significant difference was observed in the ROAT, though there was a significant difference in the time required to elicit a positive reaction. iv) The TLC patch tests indicate the presence of sensitisers other than atranol and chloroatranol in the untreated OMA sample. The studies on OMA indicate that the residual levels of atranol and chloroatranol and/or the presence of other sensitisers in the treated OMA samples may elicit allergic reactions in previously sensitised individuals.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/21e1360b-e13d-47ed-a190-b16d501109fe</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Mowitz_kappan.pdf">https://portal.research.lu.se/files/3402585/4646802.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2143969</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Occupational and Environmental Dermatology Unit</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>contact allergy</topic> <topic>allergic contact dermatitis</topic> <topic>fragrance</topic> <topic>patch test</topic> <topic>repeated open application test</topic> </subject> <subject authority="lup"> <topic>Dermatology and Venereal Diseases</topic> <topic>Occupational Health and Environmental Health</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-038-8</identifier> <identifier type="oldLupId">4646137</identifier> <part> <detail type="volume"> <number>2014:109</number> </detail> <extent unit="pages"> <total>72</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-10-03T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>21e1360b-e13d-47ed-a190-b16d501109fe</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:46+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:46+02:00</recordDateApproved> </recordInfo> </mods>

The purpose is to investigate academic development that aims to support and influence individual academic teachers and groups of teachers, in the different social collegial contexts that they work in, here called microcultures. Building on literature focused on organizational learning these microcultures are defined as constituting the meso-level within the university. Previous research shows that effects from teacher training programmes largely depend on how such programmes are valued in the teacher’s professional environment. Furthermore, previous research has shown that local teaching and learning cultures, including norms developed over time, largely influence teachers’ ways of thinking and practising. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis academic development is explored with a research-intensive Scandinavian university as a case study. The theoretical framework originates from sociocultural and network theory, as well as from organizational and leadership research. The research is presented here in five articles and shows that academic teachers rely on trusting and inspirational conversations about teaching with a few others that constitute the teacher’s significant network. The more the professional context or microculture supports such conversations, the higher the number of significant relations within the workplace. By researching microcultures as a starting point for systematic academic development at the organizational meso-level, the research further suggests that an effective strategy for academic development is to increase the number of significant relations within microcultures, as well as between them. One such strategy that is used and investigated in the case is the scholarship of teaching and learning (SoTL). SoTL can be a quality regulator for the character of the conversations within and between networks and the artefacts produced through SoTL can be used as transferrable objects of locally produced knowledge both within and between microcultures. Finally, local-level leadership is shown to have an impact on the development of microcultures, with results indicating that above all, an internal mandate needs to be established. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; By focusing on how academic teachers and leaders are mutually influenced by, and influence, their collegial context, this thesis shows that academic development, taking this into account, has the potential to contribute to organizational learning.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Alltsedan expansionen av den högre utbildningen tog fart i Sverige, i slutet av 60-talet, har universitet och högskolor arbetat för att utveckla utbildningskvaliteten. Detta har bland annat gjorts genom satsningar på policys som reglerar exempelvis arbete med kursvärderingar, mångfald, och kurs- och utbildningsplaner. Satsningar har också gjorts på pedagogisk utbildning av universitetslärare och forskare, och på pedagogiska utvecklingsprojekt som ofta drivits av eldsjälar. Många universitet och högskolor har anställt pedagogiska utvecklare och skapat särskilda enheter för att underlätta och driva på utvecklingsarbetet. Den sammantagna effekten av dessa olika satsningar är dock oklar. Många av dem är antingen alltför toppstyrda, eller i alltför hög grad individfokuserade. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Denna avhandling fokuserar pedagogiskt utvecklingsarbete i högre utbildning, i gränssnittet mellan övergripande policynivå och individnivå, den organisatoriska så kallade meso-nivån. Närmare bestämt studeras med kvalitativa metoder hur universitetslärare i en forskningsintensiv miljö (Lunds universitet) påverkas av sina närmaste kollegor och ledare i sitt sätt att tänka om och bedriva undervisning och utbildningsutveckling. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingen undersöks vem lärare vänder sig till för att prova nya idéer i undervisningen och för att bearbeta och hitta lösningar på pedagogiska utmaningar. Det framkommer att lärarna förlitar sig på ett litet antal betrodda personer, ett så kallat signifikant nätverk, som både kan utgöras av kollegor och av personer helt utanför den egna lokala organisationen. Med hjälp av teorier om sociala nätverk, organisationsutveckling och ledarskap visas också i avhandlingen att pedagogiskt utvecklingsarbete har stor potential att bidra till organisationsutveckling. Detta förutsätter ett fokus på de enskilda lärarna, inte bara som individer utan också som en del av ett kollegialt socialt sammanhang, så kallade mikrokulturer, på den organisatoriska meso-nivån. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att pedagogiskt utvecklingsarbete ska vara hållbart och kunna bidra till organisatorisk utveckling behöver interaktioner gällande lärande och undervisning inom mikrokulturerna vara starka, liksom interaktioner mellan olika mikrokulturer. Detta kan ske exempelvis genom mötesplatser och forum för diskussion och erfarenhetsutbyte, men också med hjälp av dokumenterade, underbyggda reflektioner kring undervisningsfrågor. Det sistnämnda bygger på ett synsätt på akademisk kompetens som internationellt kommit att kallas scholarship of teaching and learning, vilket innebär ett vetenskapligt förhållningssätt till undervisning och lärande. Förutom att bidra till lokalt skapad kunskap så kan sådana dokumenterade underbyggda reflektioner om undervisning spridas i organisationen, och synliggöras genom seminarier, konferenser och nyhetsbrev. De blir också möjliga underlag att använda i samband med tjänstetillsättningar, belöningar och karriärmöjligheter. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att ovanstående ska komma till stånd krävs en mängd sammanhängande, integrerade aktiviteter i en komplex och dynamisk verksamhet, vilket också ställer krav på ledarskap. Avhandlingen visar därför slutligen att lokalt ledarskap i mikrokulturerna kan bidra till att understödja pedagogisk utveckling under förutsättning att det finns eller skapas interna mandat att leda.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/009233cb-2ca0-4996-bb04-84186e036d57</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Katarina_hela_avh_G5.pdf">https://portal.research.lu.se/files/3403041/4438677.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4433121</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Academic development</topic> <topic>higher education</topic> <topic>leadership</topic> <topic>mesolevel</topic> <topic>microculture</topic> <topic>significant network</topic> </subject> <subject authority="lup"> <topic>Engineering and Technology</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-941-1 (printed)</identifier> <identifier type="isbn">978-91-7473-942-8 (pdf)</identifier> <identifier type="oldLupId">4438667</identifier> <part> <extent unit="pages"> <total>166</total> </extent> </part> </relatedItem> <note type="teachingLearningHe">yes</note> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-12T10:15:00+02:00</dateOther> <note type="additionalInfo">Department affilation moved from v1000887 (CED - Centre for Educational Development) to v1000942 (Division for Higher Education Development) on 2016-03-31 08:48:47.</note> <recordInfo> <recordIdentifier>009233cb-2ca0-4996-bb04-84186e036d57</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:55+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:55+02:00</recordDateApproved> </recordInfo> </mods>

A large proportion of the bodie&apos;s immune system is centred in the gastrointestinal tract (GI). Prolonged inflammatory conditions of the GI have been suggested to increase the risk for developing colon cancer. The cysteinyl leukotrienes (CysLTs), LTC4, LTD4 and LTE4 are inflammatory mediators that can bind to four known receptors, two of which are the CysLT1R and CysLT2R. Inhibitors of the CysLT1R are currently used in the clinic as asthma medication. LTD4 has been shown to induce cell proliferation, survival and migration in intestinal epithelial cells (Int407) via the CysLT1R. These mechanisms are often used by cancer cells to surive and spread. Furthermore, increased expression of the CysLT1R in colon cancer patient material is correlated with a poorer survival prognosis. Conversley, increased expression of the CysLT2R is correlated with a better survival prognosis. The aim of this thesis was therefore to explore the signalling and trafficking of the cysLT1R and CysLT2R. Our results demonstrate that LTD4 via the CysLT1R can activate the enzyme cPLA2-alpha. This enzyme releases arachidonic acid, the precursor of CysLTs, from the cell membranes, upon activation. One major regulatory mechanism of GPCRs is the internalization from cell membrane upon activation. We demonstrate how LTD4 mainly internalizes CysLT1R and accumulates this receptor at the nuclear membrane and that LTC4 internalizes both the CysLT1R and CysLT2R. This information is valuable in developing potential drugtargets aqainst CysLT1 and CysLT2 in cancer and inflammation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6b9b0641-bb61-4659-a399-f7e79a96bd44</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_LP.pdf">https://portal.research.lu.se/files/3406146/1275316.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2417339</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>trafficking</topic> <topic>Cysteinyl leukotriene receptors</topic> <topic>inflammation</topic> <topic>cytosolic phospholipase A2</topic> <topic>colon cancer</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-95-8</identifier> <identifier type="oldLupId">1275267</identifier> <part> <detail type="volume"> <number>2009:8</number> </detail> <extent unit="pages"> <total>139</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-01-23T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>6b9b0641-bb61-4659-a399-f7e79a96bd44</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:29:58+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:29:58+02:00</recordDateApproved> </recordInfo> </mods>

The obesity epidemic is caused by a widespread chronic energy imbalance between high-energy intake and low-energy expenditure, but this mechanism appears to be modified by a number of other biological, behavioral, and social factors that interact in a complicated manner. It has become a great challenge to understand the etiology of the global epidemic of obesity and overweight in order to design and implement policies that may counter the rapid growth of this worldwide threat to population health. Socioeconomic inequality and lifestyle factors, together with changes in the global food system and the environment, have been identified as playing a major role. The prevalence of obesity in high-income countries is greater in lower socioeconomic groups, particularly among women, but the mechanisms behind this phenomenon remain unclear, resulting in major negative implications for health equity. &lt;br/&gt;&lt;br&gt; The overall objective of this thesis was to assess the association between socioeconomic and lifestyle factors vis-à-vis weight change, overweight, and obesity among Swedish adults in Scania, Sweden. The study population is based on the data from two waves (1999/2000 and 2005) of the Scania Public Health Cohort. It was generated from a large (n = 25,000) random selection of the adult population in the region of Scania, southern Sweden. Participants completed a self-administered postal questionnaire (baseline response rate = 59%). BMI was calculated from self-reported body height and weight. Socioeconomic status was determined by means of job title and description, or by years of education. Mediating mechanisms as well as confounding control was assessed in logistic regression models with special attention to effect-modifying interactions.&lt;br/&gt;&lt;br&gt; Study I found that adult and childhood socioeconomic position influence weight gain, but differently by gender and age group. Two waves of socioeconomically determined weight gain patterns appeared in the population studied: one across generations and another contemporary one. Study II concluded that cohort effects play a role in BMI change. However, it was difficult to distinguish between age-period and cohort-period effects because of the linear relationship between age, period, and cohort, and due to the short follow-up. Study III showed a two-fold correlation between social capital and obesity: as a determinant in its own right, and as a modifier of the effect of socioeconomic status on obesity. Study IV demonstrated that women around retirement age with low and mid-level educations were at higher risk of weight gain over a five-year follow-up period, although this association could not be explained by changes in their leisure time physical activity or their social participation. &lt;br/&gt;&lt;br&gt; The thesis confirmed a relationship between socioeconomic status and overweight/obesity in the population studied. However, it concluded that these relations are highly complex and dependent on a number of individual and contextual factors that vary over time, between different age groups and birth cohorts, and by gender. The concept of social capital emerged as promising in the developing of general and specific interventions for addressing obesity and overweight on the community level. Such interventions must be created for different age groups. In this regard, the period near retirement appears to play a significant role in weight gain.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Socioekonomiska mönster av övervikt och fetma i Skåne, Sverige&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I världen idag är fetma och övervikt ett av de största hoten mot människors goda hälsa. Den här avhandlingen har försökt beskriva och öka kunskapen om hur olika faktorer, som levnadsvillkor och levnadsvanor, bidragit till ökningen av övervikt och fetma i befolkningen. Övervikt och fetma ökar risken för en rad olika sjukdomar som är vanliga i befolkningen i hög- och medelinkomstländer, som t ex diabetes, hjärt- och kärlsjukdomar, besvär i rörelseorganen, men också vissa typer av cancer, psykiska besvär och en allmänt nedsatt livskvalitet. &lt;br/&gt;&lt;br&gt; Den enkla förklaringen till utbredningen av övervikt och fetma är ett ökande energiintag och/eller minskad fysisk aktivitet. Däremot finns det fortfarande kunskapsluckor kring varför detta har skett, med begränsningar att genomföra effektiva förebyggande insatser på befolkningsnivå till följd. Detta ska också ses mot bakgrunden av hur svårt det har visat sig vara att förmå individer att ändra sina personliga kost- och motionsvanor till det bättre. &lt;br/&gt;&lt;br&gt; Eftersom övervikt och fetma i många studier har visat sig ha ett starkt samband med individens socioekonomiska situation, bidrar detta till att förstärka hälsans socialt ojämlika fördelning. I Sverige är ett hälsopolitiskt mål att minska denna ojämlikhet. Därför när det viktigt att förstå hur socioekonomiska förutsättningar hänger samman med övervikt/fetma. Med denna kunskap blir det också lättare att utveckla effektiva strategier för att uppnå detta mål. Denna kunskap är idag ofullständig&lt;br/&gt;&lt;br&gt; Avhandlingen baserar sig på analyser av data som samlats in via en stor befolkningsenkät, Folkhälsoenkät Skåne 1999/2000, till ett slumpmässigt urval av den vuxna skånska befolkningen (18 till 80 år). De cirka 13500 individer som besvarade denna enkät har följts upp med identiska frågeformulär 2005 och 2010. Det första delarbetet handlar om hur socioekonomisk position under barndomen samspelar med socioekonomisk position under vuxen ålder avseende övervikt och fetma. Socioekonomi påverkar en rad faktorer som i sin tur kan ha inflytande över val vi gör i livet, inklusive sådana som påverkar vår kroppsvikt. Ett sådant exempel är kostvanor, där valet av livsmedel beror såväl på familjens ekonomi som socialt och kulturellt bestämda värderingar. Detsamma gäller också fysiskt aktivitet i olika former. Både biologiska som sociala mekanismer kan vara involverande som överförs till vuxen ålder och medför olika former av ”ärftlighet” av socioekonomiskt betingad övervikt och fetma. Detta innebär också att förhållanden under vissa tidsperioder, t ex matransonering under kristider som en individ upplever under sin uppväxt kan påverka individens vikt genom hela livet. Avhandlingen visade att förekomsten av dessa mekanismer kunde bekräftas, men att effekten varierade mellan kvinnor och män och mellan olika åldersgrupper i befolkningen.&lt;br/&gt;&lt;br&gt; Det andra delarbetet analyserade hur den så kallade kohorteffekten, det vill säga det nämnda ”avtrycket” som uppväxt under en viss tidsperiod ger på viktutvecklingen under resten av livet, respektive den så kallade periodeffekten, det vill säga hur förhållanden under den närliggande tidsperioden (exempelvis tillgång till snabbmat, motionsanläggningar, rådande trender avseende hälsoinformation, etc.) påverkar individers viktutveckling. Denna analys tillämpade en avancerad statistisk modell som syftade till att urskilja effekten av individens kronologiska ålder, effekter under uppväxten (kohorteffekten) och förhållanden under den aktuella tidsperioden (periodeffekten). Analysen verifierade förekomsten av en kohorteffekt för såväl män som kvinnor.&lt;br/&gt;&lt;br&gt; Det tredje delarbetet avsåg en analys av effekten av så kallat socialt kapital på förekomsten av övervikt och fetma, och om ett sådant samband hade en dämpande effekt på den ökade risken för övervikt/fetma bland individer i låg socioekonomisk position. Fenomenet socialt kapital har inom forskningsfältet förts fram som en möjlig väg framåt i arbetet med att minska hälsans socialt ojämlika fördelningar. Socialt kapital definierades i denna studie som en generell tillit till andra personer, men också ett aktivt deltagande i olika sociala aktiviteter. Analyserna kunde fastslå att båda formerna av socialt kapital hade samband med övervikt och fetma, men att endast tillit till andra dämpade effekten på den ökade risken hos individer i låg social position.&lt;br/&gt;&lt;br&gt; Det fjärde delarbetet var en analys av vilka faktorer som är förknippade med en uppgång av kroppsvikten under den period som följer ålderspensionen. Det har tidigare framförts att denna period kan ytterligare öka den socialt ojämlika fördelningen av övervikt och fetma eftersom individer i låg socioekonomisk position oftare har arbeten som innebär stor eller måttlig fysisk aktivitet. Samtidigt är det vanligt bland de som haft stillasittande arbeten att de ökar sin fysiska aktivitet eller en minskar energiinnehållet i kosten. Studien kunde fastslå att männen som minskade sin fysiska aktivitet upplevde en viktökning, vilket inte var fallet bland kvinnorna.&lt;br/&gt;&lt;br&gt; Avhandlingens resultat är viktiga då den bidrar med ökade kunskaper om orsakerna till övervikt/fetmaförekomsten i den vuxna befolkningen och hur vissa av dessa orsaker hänger samman med social position. Studierna visar samtidigt att dessa samband är mycket svåra att fastställa. Därför bidrar också arbetena med inspiration till hur denna forskning kan utvecklas ytterligare. Resultaten har därför relevans såväl inom det vetenskapliga som det hälsopolitiska områdena.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/cd1c9e2d-ccbc-4b69-8eb3-d0833599ca49</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Overweight</topic> <topic>obesity</topic> <topic>socioeconomic inequality</topic> <topic>social gradient</topic> <topic>SES</topic> <topic>BMI</topic> <topic>social capital</topic> <topic>birth cohort</topic> <topic>ageing</topic> <topic>retirement</topic> <topic>Scania Public Health Cohort</topic> <topic>Sweden</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-66-6</identifier> <identifier type="oldLupId">3958323</identifier> <part> <detail type="volume"> <number>2013:94</number> </detail> <extent unit="pages"> <total>139</total> </extent> </part> </relatedItem> <note type="teachingLearningHe">yes</note> <dateOther encoding="w3cdtf" type="defenseDate">2013-09-19T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>cd1c9e2d-ccbc-4b69-8eb3-d0833599ca49</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:30:01+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:30:01+02:00</recordDateApproved> </recordInfo> </mods>

They tend to participate in lower intensity physical activity, choose more passive activities with less variety and have more sedentary time. &lt;br/&gt;&lt;br&gt; The overall aim of this thesis was to gain knowledge about participation in physical activities, to identify associated factors for school and leisure time and to explore the perceived experiences of the children and the parents about possible facilitators or barriers associated with physical activities. A further aim was to evaluate the feasibility and effectiveness of Physical Activity Referral (PAR) and outcome measures for children with physical disabilities and its effectiveness on increasing participation in physical activity and decreasing sedentary behaviour.&lt;br/&gt;&lt;br&gt; The thesis is comprised of three studies with children with various gross- and fine motor, communicative and cognitive functions. In Study I (Paper I) a total population of 364 children and adolescents with cerebral palsy (CP) aged 7-17 years was studied by using cross-sectional data from the National Quality Registry CP follow-up programme (CPUP). In Study II qualitative interviews with 16 children with CP, aged 8-11 years (Paper II), and with 25 of their parents (Paper III) were performed and analysed by content analysis. In Study III (Paper IV), 14 children with physical disabilities, aged 7-12 years, participated in PAR together with 24 of their parents. The intervention was based on a written agreement of self-selected physical activities, motivational interviewing (MI), goal-directed outcome measurements Canadian Occupational Performance measure (COPM) and Goal Attainment Scaling (GAS) and assessments including Gross Motor Function Measure (GMFM-66), physical activity monitors, the International Physical Activity Questionnaire (IPAQ) and other questionnaires at baseline, and after 8 and 11 months. &lt;br/&gt;&lt;br&gt; Children and adolescents with more severe motor limitations, with intellectual disability and with thinness seem to have the greatest needs for interventions to increase their participation in physical activities and reduce sedentary behaviour. Children discussed that they want to be asked about their wishes and needs, and get the opportunity to try self-selected physical activities with individualised support, as well as to have fun with family and friends, have someone to do the activity with and enjoy the sensation of speed. Environmental factors could be either facilitators or barriers, while pain, fatigue and the perception of not being good enough were considered barriers. The parents experienced several challenges when their child wanted to be physically active: parents wanted to protect their child while also pushing them towards independence. They wanted competent persons to be available to assist their child in participating in the physical activities and support them in finding friends to be active with. Family culture and attitudes affect children’s motivation for being physically active and should be taken into account. In Study III the families were compliant and there were no dropouts; there were positive evaluations of PAR. The families learned more about the accessibility and locations of physical activities, and the children got the opportunity to try their self-selected activities with individualised support. Several children made new friends through engaging in self-selected group activities. In addition, most children were able to maintain the physical activity levels; the outcome scores for GMFM-66, COPM and GAS were maintained for some and increased for most children. Modifications by synchronising physical activity measures into the same time periods and to give a feedback to the families close in time to the baseline measures are recommended. &lt;br/&gt;&lt;br&gt; In this thesis the children with the greatest needs of a more active lifestyle have been identified, and we have listened to their voices and talked with them and their parents before designing an individualised intervention. Families with different ethnical, cultural and socioeconomic backgrounds participated in the studies. PAR promotes an active lifestyle by increasing participation, motivation and engagement in physical activities and social participation. The intervention involves both everyday and organised habitual physical activities. To our knowledge, this is the first study about PAR in children with disabilities that measures objective and estimated physical activity. The results suggest that PAR is feasible and effective for children with physical disabilities.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/70574632-d843-4de7-9382-9c96f3884242</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Katarina_Lauruschkus_avhandlingen_webb.pdf">https://portal.research.lu.se/files/3406247/5051300.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3597425</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Child, family &amp; reproductive health</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Pediatrics</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-095-1</identifier> <identifier type="oldLupId">4940807</identifier> <part> <detail type="volume"> <number>2015:15</number> </detail> <extent unit="pages"> <total>94</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-02-13T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>70574632-d843-4de7-9382-9c96f3884242</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:30:01+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:30:01+02:00</recordDateApproved> </recordInfo> </mods>

This cardiovascular dysfunction seems to involve calcium desensitization and adrenergic unresponsiveness. We investigated the effects of clinically relevant plasma concentrations of the calcium sensitizer levosimendan during the first 6 h of endotoxemia in a model of experimental sepsis in pigs (21.8-44.0 kg). Levosimendan given to endotoxemic pigs receiving moderate volume resuscitation elicited tachycardia, hypotension and myocardial ischemia, as evidenced by a negative myocardial lactate flux (study I). Likewise, compared to non-treated controls, levosimendan did not improve systemic or hepatosplanchnic perfusion during endotoxin shock: the animals developed signs of tissue hypoperfusion with elevated blood lactate and low oxygen venous saturations (study II). Aggressive volume resuscitation before levosimendan treatment induced a hyperdynamic state that was sustained by levosimendan and norepinephrine treatment, whereas control animals gradually developed shock. Nevertheless, splanchnic blood flow was redistributed and the superior mesenteric artery, the hepatic artery and the portal vein blood flows (PVF) decreased. Similarly to study II, there were signs of systemic and hepatosplanchnic tissue hypoperfusion. In contrast, administration of dobutamine and norepinephrine, increased cardiac output (CO) and oxygen delivery, maintained PVF and improved tissue perfusion (study III). Load independent measurements of cardiac function showed that systolic function was actually enhanced during the first 2 h of sepsis, whereas diastolic function was depressed in both ventricles. The initial decrease seen in CO was a result of volume depletion, and recovered with aggressive volume resuscitation. Although endotoxin-induced lung injury caused early right ventriculovascular uncoupling and increased right ventricular (RV) myocardial oxygen demand, right coronary artery blood flow improved markedly with resuscitation, maintaining adequate myocardial perfusion (study IV). In resuscitated septic pigs, levosimendan supported RV function by increasing RV contractility at a low energy cost. CO and left ventricular ejection fraction increased, and right ventriculovascular coupling and mechanical efficiency tended to improve (study V). In conclusion, early treatment with levosimendan during resuscitated sepsis can increase CO and improves RV contractility at a low energy cost, but it does not improve hepatosplanchnic perfusion significantly, which is better achieved with dobutamine-norepinephrine. In addition, because levosimendan is an inodilator, its use in sepsis should be restricted to thoroughly fluid-resuscitated subjects.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Blodförgiftningen (sepsis) kan ge upphov till akut hjärtsvikt, vilken på cellulär nivå karakteriseras av minskad känslighet för kalciumjonen och de vanliga hjärtförstärkande medicinerna (inotropa farmaka). Avhandlingen handlar om tidig behandling av sepsis-associerad hjärtsvikt med den kalciumsensitiseraren levosimendan, ett nytt läkemedel som höjer hjärtats kontraktionskraft genom att öka de kontraktila proteinernas kalciumkänslighet i hjärtmuskelcellen. Studierna gjordes med en djurmodell där ett toxiskt ämne från gramnegativa tarmbakteriers cellvägg (E.Coli endotoxin eller LPS) injiceras hos friska djur, varvid de utvecklar ett sepsis-liknande tillstånd.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sepsis minskar blodvolymen och orsakar kärldilatation, vilket fordrar riklig vätskesubstitution. Adekvat vätskeersättning är dock svårvärderad och övervätskning medför i sig allvarliga komplikationer. Dessutom kan levosimendan vidga de små artärerna och i första studien identifierades risker med att ge medlet till septiska djur med måttlig vätskeersättning: djuren utvecklade hög hjärtfrekvens och blodtrycksfall som föranledde lokal blodbrist med bildning av mjölksyra i hjärtat. Även bukorganens genomblödning kan försämras som en följd av hjärtsvikten vid sepsis. I andra studien studerade vi bukorganens blodflöde i en liknande modell, men fann inga skyddande effekter av levosimendan. Såsom kontrolldjur utan behandlig, som djur behandlade med levosimendan utvecklade bukorgansvikt med tecken på försurning och bildning av mjölksyra. I den tredje studien fick septiska grisar aggressiv volymsubstitution, varvid de utvecklade en hyperkinetisk cirkulation med hög hjärtminutvolym. Därefter behandlades de med antingen levosimendan eller dobutamin (inotropa farmaka) eller inga läkemedel i kontroll gruppen. Ett kärlsammandragande läkemedel (noradrenalin) användes vid behov för att bibehålla adekvat blodtryck i behandlingsgrupperna. Kontroll gruppen utvecklade septisk chock, till skillnad från levosimendan-gruppen där den höga hjärtminutvolymen bibehölls. Detta skyddade dock inte bukorganen, och blodflödet dit minskade med försurning som följd. Till skillnad från levosimendan, ökade dobutamin hjärtminutvolymen och syrgasleveransen, samt förbättrade bukens organblodflöde, vilket var förenligt med adekvat cirkulation utan tecken på försurning. Bestämning av hjärtfunktionen påverkas av hjärtfyllnaden samt kärlresistensen. I det fjärde arbetet karakteriserade vi hjärtats kontraktilitet och energiförbrukning i samband med sepsis och intensiv vätskesubstitution. Vi demonstrerade att den övergående kardiovaskulära påverkan med sänkt hjärtminutvolym som inträffar i början av sepsis beror huvudsakligen på vätskebrist och svarar bra på tillförsel av volym. Dessutom konstaterade vi att hjärtats kontraktilitetsförmåga i själva verket ökar tidigt under sepsis, samtidigt som den diastoliska funktionen försämras bilateralt, vilket tydliggörs i samband med volymersättningen. Vi såg även att den lungskada som inträffar vid sepsis ökar lungkärlens motstånd, vilket höjer högerkammarens arbete och syrekonsumtion. Det sker emellertid en parallell ökning i höger kranskärls blodflöde och syrgasleverans, så att energi försörjning till hjärtmuskeln förblir adekvat. I det femte arbetet, en fortsättning av arbetet IV, studerade vi hjärtats kontraktilitet och energibalans vid levosimendanbehandling. Levosimendan ökade höger kammarens kontraktilitet utan någon ökning av hjärtmuskelns syrekonsumtion, vilket tenderade att förbättra höger kammarens energibalans. Hjärtminutvolymen samt vänster kammarens ejektionsfraktion ökade. Det fanns emellertid ingen förbättring av den diastoliska funktionen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis, på grund av risken för lågt blodtryck och medföljande regional syrebrist, bör användning av levosimendan i samband med blodförgiftning undvikas tills adekvat volymersättning försäkras. Aggressiv volymsubstitution vid sepsis framkallar en hyperdynamisk cirkulation och till en början förbättrar bukorganens genomblödning. Hjärtats kontraktionsförmåga förbättras tidigt i sepsis, men hjärtats diastoliska funktion försämras avsevärt. Dessutom blir högerkammaren tryckbelastad på grund av ökad resistens i lungkretsloppet, vilket leder till en ökning i hjärtmuskelns syrekonsumtion, som dock kompenseras av ökade blodflöde och syreleverans. Behandling av volymsubstituerade septiska grisar med levosimendan förhindrar utveckling av septisk chock, men, till skillnad från dobutamin, uppnås inga skyddande effekt mot försämrad genomblödning i bukorganen.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5ab64185-505b-467f-b3c9-0b7f5cfb216c</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>septic shock</topic> <topic>myocardial oxygen consumption</topic> <topic>myocardial dysfunction</topic> <topic>levosimendan</topic> <topic>endotoxin</topic> <topic>contractility</topic> <topic>catecholamines</topic> <topic>calcium sensitizer</topic> <topic>cardiotonic agents</topic> <topic>splanchnic perfusion</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> <topic>Anesthesiology and Intensive Care</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-78-3</identifier> <identifier type="oldLupId">1474107</identifier> <part> <detail type="volume"> <number>2009:90</number> </detail> <extent unit="pages"> <total>152</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-10-09T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>5ab64185-505b-467f-b3c9-0b7f5cfb216c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:30:12+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:30:12+02:00</recordDateApproved> </recordInfo> </mods>

Building&lt;br/&gt;&lt;br&gt; Information Modelling is of strategic importance for the development of efficient methods to&lt;br/&gt;&lt;br&gt; create, coordinate and share construction information. The introduction of BIM also allows&lt;br/&gt;&lt;br&gt; the development of construction technologies and business models, and leads to greater&lt;br/&gt;&lt;br&gt; focus on processes to achieve good urban design, architecture, and user benefit.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A prerequisite for the widespread and integrated adoption of BIM is however common&lt;br/&gt;&lt;br&gt; guidelines and a consistent approach to the development of standards for industry concepts,&lt;br/&gt;&lt;br&gt; information delivery, data storage formats and contract forms. Important knowledge and&lt;br/&gt;&lt;br&gt; established methods of information management exist and the experience gained is&lt;br/&gt;&lt;br&gt; important to utilise in this work. However, greater knowledge is needed to allow authorities&lt;br/&gt;&lt;br&gt; and practitioners to make informed decision about the content and direction of national BIM&lt;br/&gt;&lt;br&gt; guidelines and adoption prerequisites.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The study aims to support the development of applicable branch standards through building&lt;br/&gt;&lt;br&gt; knowledge on methods and processes that support organisations in their use of BIM&lt;br/&gt;&lt;br&gt; technologies. Further, within the focus domain of design methodology &amp;amp; management, it&lt;br/&gt;&lt;br&gt; seeks to contribute towards national and international initiatives and research on BIM&lt;br/&gt;&lt;br&gt; standardisation needs and support systems through testing BIM-Planning support systems,&lt;br/&gt;&lt;br&gt; developing and testing a propositional Digital Delivery Specification, presenting an&lt;br/&gt;&lt;br&gt; understanding of Contractual and Behavioural Process Obstacles, confronting the mystery of&lt;br/&gt;&lt;br&gt; Level of Development Concept and Application, and finally validating and legitimising the&lt;br/&gt;&lt;br&gt; current research and BIM standardisation efforts.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The research adopts a critical realism perspective, assumes BIM correlated units of analysis&lt;br/&gt;&lt;br&gt; and combines literature reviews with qualitative case studies culminating with a quantitative survey, and is published as 5 peer-reviewed research articles. The empirical dataset consists of 14 semi-structured interviews, 10 workshops and meetings with practitioners, 67 survey responses, plus document review and 29 feedback sessions / supplementary enquiries. The thesis is divided into 2 parts: a summary of the research, and the appended papers. The summary provides a synthesis and reflection of the findings in the papers through: 1) developing knowledge about existing BIM guidelines and testing and evaluating the application of buildingSMART’s BIM PEPG, 2) extension of the concept delivery specification via a proposed standard schema and protocol for defining model information content for selected BIM-Uses, 3) validating the need for BIM collaboration support mechanisms to address contractual and behavioural process obstacles, 4) proposing a tentative novel framework for model progression scheduling using Level of Development (LOD), 5) establishing the legitimacy of national BIM standardisation initiatives and alignment with current research efforts. Findings are drawn from empirical evidence with a focus on the Swedish context.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Based on case materials, theory and literature review, a BIM standardisation and support&lt;br/&gt;&lt;br&gt; systems model emerges constituting a set of process-based BIM procedures / measures to&lt;br/&gt;&lt;br&gt; support teams leverage their expertise, tools, and the data they create more effectively&lt;br/&gt;&lt;br&gt; thereby adding value to the project. Standards developers, BIM strategists, academics and&lt;br/&gt;&lt;br&gt; practitioners alike should be able to utilise the results from this thesis. The procedures tested are generalizable and reproducible and with some further refinement, applicable in practice. The results have implications for guidelines development and for direction finding in the advancement of BIM adoption as part of a nation vision for a fuller and more mature BIM utilisation.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; It is argued that standardisation of BIM working practices, processes and methodologies is a&lt;br/&gt;&lt;br&gt; key issue for the industry, not least for those involved in the early stages when BIM&lt;br/&gt;&lt;br&gt; information authoring is at its most intense, but also for those downstream users of the&lt;br/&gt;&lt;br&gt; digital asset. With so many processes and people involved over time from concept to&lt;br/&gt;&lt;br&gt; maintenance, to reach a steady-state of information order may be impossible. However what&lt;br/&gt;&lt;br&gt; is possible is to ensure a number of key procedures are in place to both optimise organisation&lt;br/&gt;&lt;br&gt; and stewardship of information that is critical throughout a facilities life cycle.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/adf16537-f172-4224-a978-8ed9e84f2b9f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="150328_-_BIM_Anatomy_II_-_Standardisation_Needs___Support_Systems.pdf">https://portal.research.lu.se/files/3414188/5322624.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">10034406</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University (Media-Tryck)</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Information Management</topic> <topic>Building Information Modelling</topic> <topic>BIM</topic> <topic>Standards</topic> </subject> <subject authority="lup"> <topic>Civil Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-85257-11-9</identifier> <identifier type="isbn">91-85257-11-7</identifier> <identifier type="oldLupId">5275508</identifier> <part> <extent unit="pages"> <total>233</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-08T10:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>adf16537-f172-4224-a978-8ed9e84f2b9f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:30:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:30:43+02:00</recordDateApproved> </recordInfo> </mods>

The purpose of the thesis ’Hunting for language’ is to describe and investigate how the linguistic part of Swedish is handled in upper secondary school. The study was carried out in two classes of college-preparatory programs during the first semester of the students in high school. In addition to observations of lessons, interviews with students from each class, with their Swedish teachers and with their headmasters were conducted. Further, texts produced by students and teachers were collected.&lt;br/&gt;&lt;br&gt; One background for the study consists of different conceptions of the subject Swedish and of how these conceptions are related to changes of school policy. Another important starting point is Bernstein&apos;s theory of pedagogy with its concepts of classification, and invisible and visible pedagogies. In these, the dichotomy of implicit and explicit teaching is vital and is contained, for example, in the issue of explicit versus implicit writing instruction.&lt;br/&gt;&lt;br&gt; The study shows that the linguistic part is justified in different ways. An emphasis on benefit in terms of personal growth for one’s own career appears in the textbook and the policy documents, as well in interviews with students and school leaders, which is consistent with the principle of school and education as a private good. The teachers further include an idea of personal growth, but the link to a future career is not as strong. The policy documents and the teachers also show a citizenship perspective. On the whole, the classification of the linguistic part stands out as weak. The idea of implicit learning is prominent, while, at the same time, the students and the teachers believe that teaching should be explicit. It is clear that different ideas about language and language development are intermingled in the subject Swedish without being made visible. Thus, the linguistic part of the subject Swedish appears as an example of an invisible pedagogy.&lt;br/&gt;&lt;br&gt; The observed teaching practice shows a domination of implicit instruction and a presupposed implicit learning. A strong external classification in terms of clarity regarding material selection and opening explanations by the teachers contrasts with a weak internal classification indicated by the absence of a linguistic metalanguage when working with, for instance, genres.&lt;br/&gt;&lt;br&gt; Finally, explicitness and use of metalanguage are emphasized. The subject of Swedish must try to accommodate the wishes of the students concerning language as a tool for their personal projects, while, at the same time, values embedded in the language and in the reality that language constructs are challenged and brought up for discussion.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Ett gemensamt drag i befintlig forskning är att språkliga delar av gymnasieskolans svenskämne framstår som diffusa och tycks sakna kärna och teoretisk ram. Syftet med avhandlingen På jakt efter språk är att beskriva och problematisera språkdelen i gymnasieskolans svenskämne. Undersökningen är gjord i två klasser på studieförberedande program under deras första termin i gymnasieskolan. Förutom lektionsobservationer har intervjuer gjorts med elever ur varje klass, med deras respektive svensklärare och med deras respektive rektor. Dessutom har elev- och lärarproducerade texter samlats in.&lt;br/&gt;&lt;br&gt; En bakgrund till undersökningen utgörs av olika ämnesuppfattningar och hur de är relaterade till skolpolitiska förändringar. En annan viktig utgångspunkt är Bernsteins pedagogiska teori med begrepp som klassifikation och osynlig respektive synlig pedagogik. I dessa spelar motsatsparet implicit respektive explicit undervisning en avgörande roll och återfinns i exempelvis frågan om explicit kontra implicit skrivundervisning.&lt;br/&gt;&lt;br&gt; Undersökningen visar att språkdelen legitimeras på olika sätt. En betoning av nytta i form av personlig växt för den egna karriären framträder i läroboken, i ämnets styrdokument, hos eleverna och hos rektorerna, något som stämmer väl överensstämmer med principen om skola och utbildning som ett privat projekt. Även lärarna omfattar en idé om personlig växt, men kopplingen till framtida karriär är inte lika stark. I styrdokumentet och hos lärarna finns dessutom ett medborgarperspektiv. Klassifikationen beträffande språkdelen framstår i stort sett som svag. Idén om ett implicit lärande är framträdande, samtidigt som elever och lärare menar att undervisningen bör vara explicit. Det är uppenbart att olika idéer om språk och språkutveckling samsas i svenskämnet utan att skillnader synliggörs. Språkdelen i svenskämnet framstår härigenom som ett exempel på en osynlig pedagogik.&lt;br/&gt;&lt;br&gt; Den studerade undervisningspraktiken visar att en implicit undervisning och ett förutsatt implicit lärande dominerar. En stark yttre klassifikation i form av tydlighet beträffande stoffurval och inledande förklaringar av lärarna kontrasterar mot en svag inre klassifikation uttryckt genom avsaknaden av ett språkvetenskapligt metaspråk då man arbetar med exempelvis genrer. En iakttagelse är att elever och lärare verkar hamna i en nedglidning, det vill säga en fokusering på de fenomen som lättast låter sig beskrivas, något som kan sättas i samband med avsaknaden av metaspråk. I fråga om bedömning av språket i en roman hamnar eleverna exempelvis i subjektiva värderingar.&lt;br/&gt;&lt;br&gt; Avslutningsvis betonas explicithet och användning av metaspråk. Svenskämnet måste tillmötesgå elevernas önskemål om språket som ett verktyg för det personliga projektet, samtidigt som de värderingar som finns i språket och den verklighet som språket konstruerar utmanas och ställs under debatt.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/45769e9f-0fa6-46b8-8daf-86fab112410d</url> </location> </relatedItem> <originInfo> <publisher>Malmö högskola</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>educational linguistics</topic> <topic>critical literacy</topic> <topic>school subject Swedish</topic> <topic>mother tongue subjects</topic> <topic>upper secondary school</topic> <topic>language development</topic> <topic>subject didactics</topic> <topic>writing instruction</topic> <topic>explicit teaching</topic> <topic>invisible pedagogy</topic> <topic>metalanguage</topic> <topic>grammar instruction</topic> <topic>genre pedagogy</topic> </subject> <subject authority="lup"> <topic>Languages and Literature</topic> </subject> <relatedItem type="host"> <location> <url>http://dspace.mah.se:8080/xmlui/handle/2043/11784?show=full</url> </location> </relatedItem> <relatedItem type="host"> <titleInfo> <title>Malmö Studies in Educational Sciences</title> </titleInfo> <identifier type="issn">1651-4513</identifier> <identifier type="isbn">978-91-86295-11-0</identifier> <identifier type="oldLupId">1883250</identifier> <part> <detail type="volume"> <number>60</number> </detail> <extent unit="pages"> <total>248</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>erratum-Errata.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3417429/1964123.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-04-29T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>45769e9f-0fa6-46b8-8daf-86fab112410d</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:30:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:30:53+02:00</recordDateApproved> </recordInfo> </mods>

In some cases the malformation&lt;br/&gt;&lt;br&gt; is complete and the auricle is absent. In Sweden the incidence of microtia is about 2 per 10,000 births. Reconstruction&lt;br/&gt;&lt;br&gt; of the external ear is possible by using autologous rib cartilage in three surgical steps: rib cartilage transplantation,&lt;br/&gt;&lt;br&gt; ear elevation and final adjustments.&lt;br/&gt;&lt;br&gt; Although the aesthetic result is most essential, there are also functional aspects of a reconstruction of the outer&lt;br/&gt;&lt;br&gt; ear. To keep the ear free from injury, the skin depends on a functioning alert system: sensitivity to touch, heat&lt;br/&gt;&lt;br&gt; and cold. However, the process of ear reconstruction necessarily includes surgical trauma that endangers these&lt;br/&gt;&lt;br&gt; protective systems. The blood supply of the skin cover is also impaired during the different reconstructive stages.&lt;br/&gt;&lt;br&gt; Little is known about the level and time scale of recovery of sensitivity and blood supply to the reconstructed ear&lt;br/&gt;&lt;br&gt; after surgical bisection of nerves and vessels.&lt;br/&gt;&lt;br&gt; Symmetry is important in ear reconstruction and the new ear should match the normal ear at the time of&lt;br/&gt;&lt;br&gt; reconstruction as well as in the adult life. The potential growth of the ear is a subject of debate. We decided to&lt;br/&gt;&lt;br&gt; investigate the precision of today’s tools for size measurements. With this knowledge the issue of growth hopefully&lt;br/&gt;&lt;br&gt; can be elucidated.&lt;br/&gt;&lt;br&gt; A total of 54 patients with unilateral ear reconstruction, and 30 individuals with normal ears, were included in&lt;br/&gt;&lt;br&gt; the studies. We evaluated sensitivity to heat, cold and touch in the reconstructed and normal ear. We also assessed&lt;br/&gt;&lt;br&gt; blood flow before and after body heating to investigate the pathophysiological dynamics in the reconstructed ear.&lt;br/&gt;&lt;br&gt; Digital morphometry for measuring ear size was compared to the manual methods: compass &amp;amp; ruler and callipers.&lt;br/&gt;&lt;br&gt; Measurements were performed on individuals with normal ears. In digital morphometry we also measured&lt;br/&gt;&lt;br&gt; reconstructed ears.&lt;br/&gt;&lt;br&gt; Our findings show that there is a high degree of restoration of thermosensitivity in the reconstructed ear but&lt;br/&gt;&lt;br&gt; the upper parts of the ear still show signs of reduced sensitivity to heat. Tactile sensitivity followed that of thermal&lt;br/&gt;&lt;br&gt; sensitivity, with a high degree of restoration in combination with elevated thresholds in the upper parts. The basal&lt;br/&gt;&lt;br&gt; blood flow in the reconstructed ear is compatible with that of the normal ear and its dynamic response to indirect&lt;br/&gt;&lt;br&gt; heating is also similar. Digital morphometry shows a similar reproducibility as compass &amp;amp; ruler and callipers for&lt;br/&gt;&lt;br&gt; measurement of normal ears. Digital morphometry can show great precision in measurements of reconstructed&lt;br/&gt;&lt;br&gt; ears but there is high inter-individual variation between different assessors.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Mikroti är en medfödd avvikelse där ytterörat&lt;br/&gt;&lt;br&gt; inte utvecklats normalt. Defekten kan variera&lt;br/&gt;&lt;br&gt; från att örat nästan är normalt till att det saknas&lt;br/&gt;&lt;br&gt; helt och hållet, s.k. anoti. I Sverige inträffar detta&lt;br/&gt;&lt;br&gt; i c:a 2 fall per 100 000 nyfödda. Pojkar drabbas i&lt;br/&gt;&lt;br&gt; större utsträckning och höger sida är den vanligaste.&lt;br/&gt;&lt;br&gt; Båda sidor drabbas i c:a en tiondel av fallen.&lt;br/&gt;&lt;br&gt; Förträngning av yttre hörselgången ses hos&lt;br/&gt;&lt;br&gt; en majoritet av patienterna med mikroti och det&lt;br/&gt;&lt;br&gt; föreligger i dessa fall en hörselnedsättning eftersom&lt;br/&gt;&lt;br&gt; ljudet inte når innerörat.&lt;br/&gt;&lt;br&gt; En ensidig mikroti kan rekonstrueras i tre&lt;br/&gt;&lt;br&gt; seanser genom att använda det egna revbensbrosket.&lt;br/&gt;&lt;br&gt; Brosket formas till ett öra och placeras&lt;br/&gt;&lt;br&gt; i en ficka under huden på örats plats för att i ett&lt;br/&gt;&lt;br&gt; senare skede resas och slutligen finjusteras. Rekonstruktionen&lt;br/&gt;&lt;br&gt; kan påbörjas när bröstkorgsomfånget&lt;br/&gt;&lt;br&gt; är tillräckligt. Patienten skall också vara&lt;br/&gt;&lt;br&gt; välmotiverad och så långt möjligt är förstå vad&lt;br/&gt;&lt;br&gt; operationerna kommer att innebära i form av tid&lt;br/&gt;&lt;br&gt; på sjukhus, smärta, konvalescens etc. I praktiken&lt;br/&gt;&lt;br&gt; kan rekonstruktionsförfarandet därmed oftast&lt;br/&gt;&lt;br&gt; påbörjas vid 6–7 års ålder.&lt;br/&gt;&lt;br&gt; Under de tre kirurgiska stegen kommer mottagarområdet&lt;br/&gt;&lt;br&gt; att utsättas för ett flertal snitt där&lt;br/&gt;&lt;br&gt; såväl nerver som blodkärl måste delas. Vidare&lt;br/&gt;&lt;br&gt; görs en friläggning under huden så att brosket&lt;br/&gt;&lt;br&gt; kan få plats. Huden som täcker örat riskerar därmed&lt;br/&gt;&lt;br&gt; att mista viktiga skyddsfunktioner såsom&lt;br/&gt;&lt;br&gt; känsel för värme, kyla och tryck. Ett rekonstruerat&lt;br/&gt;&lt;br&gt; öra utan dessa skyddsfunktioner i huden&lt;br/&gt;&lt;br&gt; skulle mycket väl kunna löpa större risk för sårbildning&lt;br/&gt;&lt;br&gt; till följd av skador av olika slag. Ett sår&lt;br/&gt;&lt;br&gt; i huden skulle i sig kunna äventyra det underliggande&lt;br/&gt;&lt;br&gt; broskskelett och därmed hela rekonstruktionen.&lt;br/&gt;&lt;br&gt; Att utvärdera känsel för värme, kyla och tryck&lt;br/&gt;&lt;br&gt; i det rekonstruerade örat är således angeläget och&lt;br/&gt;&lt;br&gt; inom ramen för våra studier har detta skett. Vi&lt;br/&gt;&lt;br&gt; har också undersökt blodflödets återhämtning&lt;br/&gt;&lt;br&gt; och reglering.&lt;br/&gt;&lt;br&gt; Det rekonstruerade örat dimensioneras för&lt;br/&gt;&lt;br&gt; att matcha det normala örat. En sjuårings öra&lt;br/&gt;&lt;br&gt; växer mindre än 7,5 mm fram till 18 års ålder.&lt;br/&gt;&lt;br&gt; Huruvida det rekonstruerade örats brosk växer är&lt;br/&gt;&lt;br&gt; omdebatterat men klinisk erfarenhet samt vissa&lt;br/&gt;&lt;br&gt; vetenskapliga rön talar för att det finns en tillväxtpotential&lt;br/&gt;&lt;br&gt; hos det transplanterade brosket. I&lt;br/&gt;&lt;br&gt; ett led att på sikt kunna utvärdera brosktillväxten&lt;br/&gt;&lt;br&gt; i anslutning till öronrekonstruktion har vi i&lt;br/&gt;&lt;br&gt; första hand utvärderat mätmetoden digital morfometri,&lt;br/&gt;&lt;br&gt; dvs. storleksmätning på digitala foton&lt;br/&gt;&lt;br&gt; med därtill avsedd mjukvara. Metoden jämfördes&lt;br/&gt;&lt;br&gt; med de två manuella metoderna passare &amp;amp;&lt;br/&gt;&lt;br&gt; linjal samt skjutmått.&lt;br/&gt;&lt;br&gt; Våra fynd visar att det finns en hög grad av&lt;br/&gt;&lt;br&gt; återhämtning av känseln för värme och kyla i&lt;br/&gt;&lt;br&gt; det rekonstruerade örat även om något nedsatt&lt;br/&gt;&lt;br&gt; känsel för värme noterades i örats övre del. Känsel&lt;br/&gt;&lt;br&gt; för tryck visade samma mönster med en hög&lt;br/&gt;&lt;br&gt; återhämtning i kombination med något höjda&lt;br/&gt;&lt;br&gt; tröskelvärden i den övre delen. Blodflödet i det&lt;br/&gt;&lt;br&gt; rekonstruerade örat var väsentligen lika med det&lt;br/&gt;&lt;br&gt; normala örat och vid kroppsuppvärmning ökade&lt;br/&gt;&lt;br&gt; blodflödet på likartat sätt. Digital morfometri visade&lt;br/&gt;&lt;br&gt; samma grad av slumpfel som passare &amp;amp; linjal&lt;br/&gt;&lt;br&gt; samt skjutmått när normala öron mättes.

Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health.&lt;br/&gt;&lt;br&gt; One goal of this thesis was to determine two microbial markers (3-hydroxy fatty acids of bacterial lipopolysaccharide and ergosterol of fungal biomass) in waterpipe smoke. A second goal was to study the influence of relative humidity (RH) on room air concentrations of VOCs. A third goal was to study the performance of a new device called the surface emissions trap (cTrap) in controlling indoor pollutants.&lt;br/&gt;&lt;br&gt; Smoking waterpipe was found to generate a bioaerosol rich in microbial components, policyclic aromatic hydrocarbons (PAHs), and small size particles. Rapidly increasing RH was found to influence air concentrations of VOCs emitted from building materials as studied both in a climate chamber and in a room with dampness-related floor emissions. The cTrap cloth was found to be efficient in reducing emissions of VOCs, stopping mycotoxins, and improving the perceived IAQ in a damp school building. The device was proved to be efficient in reducing and trapping moisture-driven floor emissions. Preliminary results also showed that the cloth may be used in reducing smoking generated VOCs and particles which may migrate between rooms within a building.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Det är känt att kvalitén på inomhusluften har en avgörande betydelse för folkhälsan bla avseende astma, eksem samt luftvägsinfektioner. Detta är ett för samhället mycket kostsamt problem.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingen har studerats vissa luftföroreningar inomhus som kan bli följden av att en byggnad drabbats av fuktskada. När fukt påverkar byggnadsmaterial frigörs och bildas en rad organiska ämnen, såsom olika reaktions- och nedbrytningsprodukter, mögelämnen mm, som sprids i luften inomhus. I avhandlingen visas att resultaten från luftmätningar inomhus avseende vissa sådana ämnen starkt påverkas av den relativa fuktigheten vilket är ett fynd av stor betydelse då sådana mätningar ofta används för bedömning av luftkvalitén och får styra efterföljande åtgärder. En ny metod och ett nytt material, den så-kallade cTrap-duken, utvecklades och tillämpades för att reducera luftkoncentrationerna av ämnen som sprids från ytor inomhus (golv, väggar och tak), framför allt vid fuktskada, och som därför kan komma att spela en stor roll i strävan efter en förbättrad folkhälsa. cTrap-duken visade sig kunna reducera luftkoncentrationerna av sådana föroreningar med upp till 100%. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; cTrap-duken visade sig också vara effektiv för att stoppa partiklar och organiska ämnen i tobaksrök. I avhandlingen har särskilt studerats rök från vattenpipa eftersom denna typ av tobaksrökning blir alltmer populär. Studierna visade att vattnet i vattenpipan kunde minska koncentrationerna i röken av vissa mikrobiella ämnen men att avsevärda koncentrationer av sådana ämnen samt av vissa polyaromatiska kolväten ändå kvarstår i röken. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De resultat som vunnits av detta avhandlingsarbete kan komma att förbättra möjligheterna att snabbt och enkelt återställa en god luftkvalité inomhus efter att en byggnad drabbats av fuktskada.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f4f2f9fe-4381-438e-a14e-3c936acde18e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Pawel_Markowicz.pdf">https://portal.research.lu.se/files/3421119/4770166.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">17113797</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Medical Microbiology</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>indoor air quality</topic> <topic>indoor pollutants</topic> <topic>dampness</topic> <topic>purification</topic> <topic>tobacco smoke</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-058-6</identifier> <identifier type="oldLupId">4770127</identifier> <part> <detail type="volume"> <number>2014:129</number> </detail> <extent unit="pages"> <total>92</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-11-28T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>f4f2f9fe-4381-438e-a14e-3c936acde18e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:31:16+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:31:16+02:00</recordDateApproved> </recordInfo> </mods>

Age, ethnicity, and family history are the only established risk factors. Type 2 diabetes mellitus (T2D) has been found to associate with increased overall cancer risk but with lower risk of specifically PCa. T2D is initially associated with increased blood glucose, insulin and insulin-like growth factor-1 levels. However, after long disease duration, insulin production diminishes and among men testosterone levels decrease. In healthy men, blood glucose and insulin levels are affected by various lifestyle factors, including diet and physical activity. Since lifestyle factors and T2D are associated with a range of health outcomes other than PCa, so called competing events, estimation of their association with PCa may be biased due to longer survival among men with healthy lifestyles and non-diabetics. Further, there is evidence to suggest that T2D and cancer may share some genetic risk factors. The effect of the strongest T2D risk variant to date, TCF7L2 rs7903146, has been shown to be modified by dietary and lifestyle factors. This doctoral project consisted of four epidemiological studies in the population-based, prospective Malmö Diet and Cancer Study. The cohort includes 11,063 men with information on dietary habits, socioeconomic and lifestyle factors, disease history, anthropometric measurements, and blood samples. Among this population (aged 45-73 at baseline), 10,578 men were free of cancer at baseline, and 1,016 men were subsequently diagnosed with PCa until 31 December 2009. We found that high intakes of refined carbohydrates (primarily sugar-sweetened beverages) may increase the risk of incident PCa. In a nested case-control study we found that a biomarker for whole-grain intake, plasma alkylresorcinol metabolites, was positively correlated with whole-grain intake but not with lower risk of PCa. Men with prevalent diabetes at study baseline had a lower risk of PCa diagnosis, partly attributed to a higher risk of non-cancer deaths. In contrast, we found that incident T2D may increase the risk of high-risk PCa. The TCF7L2 T2D genetic risk variant was not significantly associated with PCa, however, carriers of the risk allele who were hyperglycemic at baseline or reported unhealthy lifestyles had a higher risk of incident PCa. In conclusion, this project showed that there may be an association between diet, T2D, and risk of PCa that is potentially mediated by metabolic changes and modified by genetic factors. Survivor bias may be of particular concern in epidemiological studies on PCa.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Prostatacancer är den vanligaste formen av cancer hos män i Sverige och ungefär 10 000 män diagnosticeras årligen. Prostatacancer tros orsakas av en kombination av ärftliga faktorer och miljö-/livsstilsfaktorer. De enda väletablerade riskfaktorerna för prostatacancer är ålder, etnicitet och ärftlighet inom familjer. För att kunna arbeta med förebyggande av denna sjukdom forskas det mycket på möjliga livsstilsfaktorer som är kopplade till prostatacancer, eftersom dessa går att förändra. Bättre kunskap om olika riskfaktorer, inklusive genetiska faktorer, kan även bidra till att man snabbare kan identifera personer med förhöjd risk för prostatacancer samt leda till nya behandlingsmetoder. &lt;br/&gt;&lt;br&gt; Detta avhandlingsprojektet grundar sig på insamlande uppgifter och material från en stor befolkningsbaserad kohortstudie, Malmö Kost och Cancer. Under första halvan av 1990-talet etablerades kohorten och alla invånare i Malmö födda mellan 1923-1950 inbjöds att delta. Av de som kallades deltog ca. 40% i studien, varav 11 063 var män. Deltagarna fyllde i ett omfattande frågeformulär om socioekonomiska och livsstilsfaktorer, man mätte längd, vikt och midjeomfång, och samlade in blodprover som sparats i en biobank. Utöver detta så uppskattades deltagarnas kostintag med hjälp av en omfattande kostundersökning som inkluderade ett frågeformulär, en kostdagbok, samt en kostintervju. Deltagarna har sedan studiestarten följts via flera olika register. Från studiens början fram till slutet av uppföljningtiden (31 december 2009) insjuknade drygt 1000 män i prostatacancer. &lt;br/&gt;&lt;br&gt; Det har tidigare föreslagits att fiberrik kost, framförallt fullkorn, skulle kunna skydda mot prostatacancer. Likaså tros en mindre fiberrik kost med högt intag av raffinerade spannmålsprodukter och socker öka risken för prostatacancer. En bakomliggande biologisk mekanism för ett sådant samband skulle kunna vara att kolhydrater (beroende på typ och livsmedelskälla) påverkar blodsockernivåerna efter måltid, och att en kost som leder till höga blodsockernivåer leder till förhöjda nivåer av insulin och andra tillväxtfaktorer (t ex insulin-like growth factor 1, IGF-1). Insulin och IGF-1 har kopplats till ökad cancerrisk, framförallt genom att stimulera cancercellernas tillväxt. Fullkorn innehåller också flera bioaktiva komponenter, t e x fytoöstrogener, vitaminer och mineraler, som i sig skulle kunna påverka risken att insjukna i prostatacancer. &lt;br/&gt;&lt;br&gt; Diabetes har kopplats till ökad risk för flera olika cancerformer. Att diabetiker ofta har visats ha en lägre risk att insjukna i specifikt prostatacancer har därför genererat stort intresse. I det tidiga sjukdomsförloppet har typ 2-diabetiker förhöjt blodsocker och högre insulinnivåer än friska individer, men senare i förloppet, när de insulinproducerande cellerna i bukspottskörteln successivt blir överarbetade så får även typ 2-diabetiker insulinbrist. Man har också sett att höga blodsockernivåer kan leda till lägre testosteronnivåer hos diabetiker på grund av negativ inverkan på de testosteronproducerande Leydig cellerna i prostatakörteln. Det finns alltså en biologisk trovärdighet i att typ 2-diabetes möjligen initialt ökar risken för prostatacancer, men att långtidsdiabetiker har en lägre risk. Diabetiker har en förhöjd risk att insjukna i hjärtkärlsjukdom och därmed en ökad risk att dö i förtid. Den höga dödligheten hos diabetiker skulle kunna leda till att att man i epidemiologiska studier observerar en lägre grad av insjuknande i prostatacancer hos diabetiker då dessa i lägre utsträckning lever vid den ålder då prostatacancer oftast diagnosticeras (i genomsnitt vid 70 års ålder). Idag finns det flera olika genetiska varianter som har kopplats till risk att insjukna i både typ 2-diabetes och prostatacancer. Den starkaste riskgenen för typ 2-diabetes är transcription factor 7-like 2 (TCF7L2). Tidigare studier har visat att sambandet mellan en vanlig variant i denna gen och risken att insjukna i typ 2-diabetes påverkas av kostfaktorer, bland annat fiberintag. &lt;br/&gt;&lt;br&gt; I denna avhandling studerades sambandet mellan kolhydratintag (specifikt olika typer och livsmedelskällor för kolhydrater) och prostatacancer. Även om vi har haft tillgång till mycket detaljerade data avseende kostintag hos männen i Malmö Kost och Cancer studien, så är det generellt svårt att mäta kostintag eftersom man förlitar sig på självrapporterade intag. Därför undersöktes även en möjlig biomarkör för fullkornsintag, alkylresorcinolmetaboliter. Vi tittade på vilka kost- och livsstilsfaktorer som korrelerar med plasmanivåer av denna biomarkör samt undersökte sambandet mellan alkylresorcinolmetaboliterna och risken att insjukna i prostatacancer. Generellt kunde inget starkt samband mellan totalt intag av kolhydrater eller fiber/fullkorn och risk att insjukna i prostatacancer observeras. Däremot såg vi ett samband mellan höga intag av sockersötade drycker (saft och läsk), samt vissa andra produkter med högre innehåll av raffinerat spannmål och socker, och risk att insjukna i prostatacancer, vilket skulle kunna tyda på att en kost med högt sockerintag kan öka risken för prostatacancer. Fullkornsintag samvarierade med plasmanivåer av alkylresorcinolmetaboliter, men vi kunde inte finna något stöd för att ett högt fullkornsintag skyddar mot insjuknande i prostatacancer i denna studiepopulationen. &lt;br/&gt;&lt;br&gt; Vi undersökte även sambandet mellan typ 2-diabetes och risken att insjukna i prostatacancer. I likhet med tidigare studier fann vi att män som hade diabetes när de gick med i Malmö Kost och Cancer studien hade en något lägre risk att insjukna i prostatacancer. När män som diagnosticerades med typ 2-diabetes under uppföljningstiden studerades separat, dvs de män som kunde följas från den faktiska diabetesdiagnosen och framåt, fann vi att dessa hade ungefär 50 % högre risk att insjukna i aggressiv och/eller metastaserande prostatacancer. Eftersom diabetiker har en ökad risk inte bara för tidig död utan även för insjuknande i andra cancerformer, studerade vi den möjliga effekten av andra utfall på sambandet mellan diabetes och prostatacancer, så kallade konkurrerande risker. Det visade sig att framförallt de män som hade diabetes när de gick med i studien (och också haft sin diabetes under längre tid vid eventuellt insjuknande i prostatacancer) hade nästan två till tre gånger så hög risk att dö i icke-cancer relaterade sjukdomar. Detta samband innebär att sannolikheten att en långtidsdiabetiker diagnosticeras med prostatacancer är lägre än den för icke-diabetiker. Konkurrerande risker skulle därför kunna vara en alternativ förklaring till det skyddande samband mellan diabetes och prostatacancer som ofta observerats i epidemiologiska studier. Män som vid studiens start hade diabetes rapporterade också generellt en mer hälsosam livsstil, något som i sig skulle kunna leda till att de har en lägre risk att insjukna i prostatacancer. &lt;br/&gt;&lt;br&gt; Inget signifikant samband mellan typ 2-diabetes riskgenen (TCF7L2) och risken att insjukna i prostatacancer kunde observeras. Dock så fann vi indikationer på att män med typ 2-diabetes och framförallt män med hyperglycemi (dvs förhöjt blodsocker) hade en ökad risk för prostatacancer om de var bärare på riskgenen för typ 2-diabetes. Likaså hade män med riskgenen som samtidigt rapporterade en ohälsosam livsstil en ökad risk för prostatacancer. En ohälsosam livsstil definerades som antal riskfaktorer, inklusive lågt fiberintag och högt intag av sockersötade drycker, rökning, hög alkoholkonsumption, fysisk inaktivitet och stort midjeomfång. Den ökade risken sågs framförallt hos män med tre eller fler av dessa livsstilsriskfaktorer. &lt;br/&gt;&lt;br&gt; Sammantaget visar studierna i denna avhandling att möjliga livsstilsrelaterade riskfaktorer för prostatacancer är svårstuderade i epidemiologiska studier. Prostatacancer är en heterogen sjukdom och sambanden mellan livsstilsfaktorer och risk att insjukna i prostatacancer kan skilja sig mellan mer aggressiva former jämfört med mildare former av sjukdomen. Det är möjligt att män med hälsosam livsstil oftare begär utredning för prostatacancer (med hjälp av t ex PSA-tester), vilket skulle kunna öka antalet diagnoser hos dessa män. Hälsosamma män har också en lägre risk att insjukna eller dö i andra sjukdomar som inträffar tidigare i livet och har därför högre sannolikhet att diagnosticeras med prostatacancer. Detta kan försvaga de sambanden man observerar i epidemiologiska studier och kan även, som i fallet med diabetes, skapa snedvridna samband. Identifiering av subgrupper av individer med genetiskt förhöjd risk att insjukna i prostatacancer, och kunskap om hur deras risk att insjukna påverkas av livsstilfaktorer, är ett viktigt steg i förebyggande arbete. Fler studier behövs för att undersöka de samband som framträtt i våra studier, bland annat om en kost med högt sockerintag, typ 2-diabetes och möjliga interaktioner mellan gener och livsstil påverkar risken att insjukna i prostatacancer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/25f23c2c-2349-4a30-86e0-8faa6b71ff47</url> </location> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>carbohydrates</topic> <topic>cohort</topic> <topic>competing risk</topic> <topic>diabetes mellitus</topic> <topic>diet</topic> <topic>epidemiology</topic> <topic>fiber</topic> <topic>gene</topic> <topic>gene-environment</topic> <topic>lifestyle</topic> <topic>prostate cancer</topic> <topic>survivor bias</topic> <topic>transcription factor 7-like 2</topic> <topic>whole-grain</topic> <topic>alkylresorcinol metabolites</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-012-8</identifier> <identifier type="oldLupId">4586668</identifier> <part> <detail type="volume"> <number>2014:83</number> </detail> <extent unit="pages"> <total>106</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-09-08T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>25f23c2c-2349-4a30-86e0-8faa6b71ff47</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:31:23+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:31:23+02:00</recordDateApproved> </recordInfo> </mods>

The method was used to diagnose the first case of wound botulism in an injecting drug user in Sweden, which was also the first case of wound botulism reported to be caused by C. botulinum type E. It was previously assumed that only proteolytic C. botulinum could cause infectious botulism. However, this case revealed that wound botulism can be caused by nonproteolytic C. botulinum. &lt;br/&gt;&lt;br&gt; When developing new food products it is important to consider not only the occurrence and quantity of pathogens in the food chain, but how the processing and subsequent storage and handling will affect them. Especially for food designed to have a long shelf-life, understanding the influence of environmental factors, food preservatives, and type of packaging on microbial growth and virulence expression is very important.&lt;br/&gt;&lt;br&gt; Quantitative reverse transcription PCR (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA) were used to monitor the neurotoxin expression in C. botulinum types A, B, and E. The relative cnt expression varied with growth phase in all three types, reaching a maximum as the late exponential phase was changing into stationary phase. However, for the proteolytic type A, a second increase could be seen in late stationary phase in contrast to type E. The same behaviour has earlier been observed for proteolytic C. botulinum type B with a second increase in cntB mRNA when the bacteria reached the death phase. For the nonproteolytic C. botulinum type E the cntE expression declined rapidly after the peak in the transition between exponential and stationary phase. The cntE mRNA half-life was calculated to be approximately nine minutes. &lt;br/&gt;&lt;br&gt; When investigating the effect of carbon dioxide on growth and neurotoxin expression, we found that while proteolytic type A was not affected in either regard, the nonproteolytic types B and E were. Their growth was slowed, but the relative cnt expression was increased with an elevated CO2 concentration, with fivefold higher levels of cntB mRNA and type B toxin being detected at 70% CO2 than at 10%. For type E the increase in expression at 70% CO2 was two-fold greater, when compared with 10% CO2. For the proteolytic strain Hall A microarrays were also used to follow the genome-wide expression profiles. Comparison between the results from the qRT-PCR and the microarrays shows that both methods seem valid, as the results are similar. For example, the expression of the positive regulator gene, cntR, followed the same pattern as cntA, but at a much lower level.&lt;br/&gt;&lt;br&gt; In conclusion, our findings, confirmed with both qRT-PCR and ELISA, shed a new cautionary light on the potential risks of botulism associated with nonproteolytic C. botulinum and the use of modified atmosphere packaging. In addition, our PCR method was successfully used on clinical samples and proved to be a valuable complement to standard methods.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5feb3ae1-646b-4a47-8f3f-6e72a041eec9</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_080121.pdf">https://portal.research.lu.se/files/3427635/1022331.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1515530</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Divison of Medical Microbiology</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>detection</topic> <topic>qRT-PCR</topic> <topic>Clostridium botulinum</topic> <topic>molecular methods</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-68-1</identifier> <identifier type="oldLupId">1022281</identifier> <part> <detail type="volume"> <number>2008:15</number> </detail> <extent unit="pages"> <total>157</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-02-29T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>5feb3ae1-646b-4a47-8f3f-6e72a041eec9</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:31:30+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:31:30+02:00</recordDateApproved> </recordInfo> </mods>

As our reliance on software-based systems increases, our tolerance with software that is ill-fitted to our needs decreases. We expect these devices to function whenever and however we need them to. However, developing these (often) large and complex software systems to meet our needs and to be usable and robust is non-trivial. Yes, it requires good tools and methods, and competent software engineers that are good at design, development, testing and debugging. But, equally important is that the engineers can coordinate their activities and work together on developing the right thing. Figuring out what the right thing is, i.e. defining the requirements, and then ensuring that the whole development team joins together in realising this is a major challenge.&lt;br/&gt;&lt;br&gt; When there are gaps between requirements and other development activities these gaps have a negative impact on the success of a project and a product. Similarly when there are no gaps, or they are effectively managed and bridged, the development process can run more smoothly and the project stands a better chance of delivering the required functionality, with good quality and on time.&lt;br/&gt;&lt;br&gt; The main topic of this thesis is the collaboration and alignment of requirements within software development, and how this can enable a development company to consistently develop and deliver products that are well received by their users. A number of challenges and practices including factors contributing to these have been identified through industrial case studies. Furthermore, this thesis includes two methods for supporting project teams in improving on their work practices. Both methods have been applied in live development projects and found to enable teams to reflect on their practices and consider what gaps there are between people, between activities and between artefacts. By doing so, they can gain insight into how to improve on their coordination and alignment of requirements.&lt;br/&gt;&lt;br&gt; The main conclusion of this thesis is that development as a whole can be improved with an integrated requirements engineering (iRE) approach. Understanding and bridging gaps, or the level of integration between requirements and other development activities, helps development teams in achieving the necessary collaboration to be aligned within the development projects. This then enhances the efficiency and effectiveness of the development process by ensuring that the right thing is developed.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/77ffcc12-b5f5-44b7-bfae-4e4ad3f6a3ac</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="BjarnasonThesis.pdf">https://portal.research.lu.se/files/3427902/4117182.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4014684</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Computer Science, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>software engineering</topic> <topic>requirements engineering</topic> <topic>communication</topic> <topic>empirical research</topic> </subject> <subject authority="lup"> <topic>Computer Sciences</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-732-5 (print)</identifier> <identifier type="isbn">978-91-7473-733-2</identifier> <identifier type="oldLupId">4117175</identifier> <identifier type="other">LU-CS-DISS: 2013-02</identifier> <part> <extent unit="pages"> <total>272</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popsciencePopular science.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3427900/4144369.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-11-22T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>77ffcc12-b5f5-44b7-bfae-4e4ad3f6a3ac</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:31:34+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:31:34+02:00</recordDateApproved> </recordInfo> </mods>

The prevalence of PN is rising with the global burden of type 2 diabetes. The causal mechanisms of PN are not fully understood, but both vascular and metabolic factors play a role. New methods of investigating PN need to be correlated with standard methods in well-defined, population-based cohorts. &lt;br/&gt;&lt;br&gt; Objectives: The overall aim was to investigate endoneurial microvascular abnormalities of the sural nerve and intraepidermal nerve fiber loss in type 2 diabetes and impaired glucose tolerance (IGT), in relation to glucose dysmetabolism, and clinical and neurophysiological measures of PN. &lt;br/&gt;&lt;br&gt; Methods: Subjects were recruited from a prospective, population-based study of males from Malmö, Sweden (6956 responders). From this cohort, 182 individuals in three groups were identified, [69 with type 2 diabetes, 51 IGT, and 62 normal glucose tolerance (NGT)], matched for age, height, and body mass index (BMI). Endoneurial microangiopathy and myelinated nerve fiber density (MNFD) were assessed in 30 sural nerve biopsies (from 10 men with type 2 diabetes, 10 IGT, and 10 NGT). Intraepidermal nerve fibers (IENF) were assessed in skin biopsies from the distal leg in 86 subjects (50 men with type 2 diabetes, 15 IGT, and 21 NGT) and graded as absent IENF, low (1–3 IENF/section), or high (&amp;gt; 4 IENF/section) counts of IENF. The subjects underwent oral glucose tolerance test, clinical examination (Total Neuropathy Score; combined Neuropathy Symptom Score and Neuropathy Disability Score), and neurophysiological tests (nerve conduction and quantitative sensory testing) at baseline and at follow-up (6–10 years later). Vibrotactile sense of the index (median nerve) and little fingers (ulnar nerve) was assessed in 58 subjects (23 type 2 diabetes, 7 IGT, 28 NGT) with persistent glucose tolerance for 15 years. &lt;br/&gt;&lt;br&gt; Results: Increased endoneurial capillary density was linked to current diabetes and future progression from IGT to diabetes. Decreased capillary luminal area was associated with deterioration of glucose tolerance. Increased basement membrane area was related to clinical PN. A low baseline sural nerve MNFD (&amp;lt; 4700 fibers/mm2) was associated with future progression of neurophysiological dysfunction in the peroneal and median nerves. MNFD correlated negatively with BMI. Absence of IENF was related to low sural nerve amplitude and conduction velocity, and high cold perception threshold. Vibrotactile sense was impaired in the index and particularly the little finger of diabetic subjects, mainly at high frequencies (250–500 Hz). IGT did not affect vibrotactile sense.&lt;br/&gt;&lt;br&gt; Conclusions: Sural nerve endoneurial microangiopathy is related to glucose dysmetabolism and clinical PN. MNFD may predict future nerve dysfunction. Obesity may be a risk factor for PN. IENF count correlates with neurophysiological measures of PN. Vibrotactile sense is impaired in the fingers, particularly innervated by the ulnar nerve at high frequencies, in patients with type 2 diabetes but not those with IGT.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1dc67398-a21d-44c7-882c-50bac5b5249e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Soley_9juli.pdf">https://portal.research.lu.se/files/3427954/1466067.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">975120</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>nerve conduction studies</topic> <topic>skin biopsy</topic> <topic>intraepidermal nerve fibers</topic> <topic>Diabetic neuropathy</topic> <topic>sural nerve pathology</topic> <topic>body mass index</topic> <topic>quantitative sensory testing</topic> <topic>vibrotactile sense</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-55-4</identifier> <identifier type="oldLupId">1466061</identifier> <part> <detail type="volume"> <number>2009:67</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-09-18T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

The Swedish National Registry for individuals with severe AATD was started 1991.Up to October 2008, a total of 1349 individuals were included in the registry. The aims of the studies in this thesis which bases on AATD registry are to analyse the mortality of PiZZ individuals with respect to smoking habits and mode of identification, to analyse the predictors of mortality and to analyse the most common causes of death, by including a large number of never-smoking individuals. Further aims were to assess whether there is a survival benefit of lung transplantation in PiZZ individuals with severe emphysema.&lt;br/&gt;&lt;br&gt; In study I and II, the PiZZ individuals had a significantly increased mortality risk compared with general Swedish population. We found that the smokers had a significantly higher mortality rate than the never-smokers and than the general population. The never-smoking individuals identified by screening did not have an increased mortality risk compared with the general population. Emphysema is still the main underlying cause of death in smoker-and never-smokers. Liver cirrhosis-related mortality seems to be increased in elderly never-smoking individuals, cirrhosis and its complications were the cause of death in 26 of 93 never-smokers. Increasing age, decreasing FEV1 % of predicted value and presence of respiratory symptoms were associated with increased mortality risk in PiZZ individuals.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Study III shows a significant survival benefit for lung transplantation in PiZZ individuals with severe emphysema, with an estimated median survival time of 11 years compared to 7 years in the non-transplant patients. Furthermore, in Sweden, patients seem to be referred to the lung transplantation centers late in the disease which may result in an unnecessarily increased mortality for this group of patients.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In study IV we did not find any significant differences in age, gender or smoking habits between the index and non-index siblings. Neither was there any significant difference in lung function at inclusion. Our study population was young in both groups with a mean age of 40 years or younger and the majority of both them were identified by screening.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Svår alfa-1antitrypsinbrist (AAT-brist), s.k. PiZZ, är ett ärftligt tillstånd som har en hög förekomst i Sverige, cirka 1/1600. Bristen innebär ökad risk för utveckling av kroniskt obstruktiv lungsjukdom (KOL), speciellt hos rökare. Leversjukdom är också relativt vanlig och kan förekomma såväl i barndomen som i hög ålder. Levercirros (skrumplever) och levercancer är överrepresenterade i hög ålder. Andra ovanliga manifestationer kan förekomma vid svår AAT-brist, t.ex. vaskulitsukdomar (inflammation i blodkärl) och pannikulit (inflammation i underhudsvävnad). &lt;br/&gt;&lt;br&gt; Det svenska nationella registret över personer med svår AAT-brist startades 1991. De främsta syften är att öka kunskapen om tillståndet och samtidigt förebygga lungsjukdom genom anti-rökinformation, att studera AAT-bristens naturalhistoria och att stimulera släktundersökningar. Kriterier för inklusion i registret är ålder ≥18 år, PiZZ fenotyp verifierad på Klinisk kemisk avdelning, Skånes universitetssjukhus i Malmö, samt skriftligt samtycke. &lt;br/&gt;&lt;br&gt; I oktober 2008 ingick sammanlagt 1349 personer i registret, vilket motsvarar en hög andel, 30 % av alla vuxna PiZZ-individer i Sverige.&lt;br/&gt;&lt;br&gt; Tidigare studier av AAT-bristens naturalförlopp har varit få och inkluderat främst rökare och personer som identifierats pga. luftvägssymtom. Dessa studier har visat att svår AAT-brist är en allvarlig sjukdom som leder till för tidig död.&lt;br/&gt;&lt;br&gt; Syftet med studierna i denna avhandling som är baserade på AAT-registret var att analysera överlevnad vid svår AAT-brist med avseende på rökvanor och hur personerna har identifierats, att analysera vilka faktorer som påverkar risken att dö och att analysera de vanligaste dödsorsakerna. Skillnaden med tidigare publicerade studier är att vi har inkluderat ett stort antal bristindivider som aldrig har rökt (icke-rökare). Ytterligare syften var att studera om lungtransplantation förbättrar överlevnaden hos bristindivider med svårt emfysem och att studera lungfunktion hos syskon med svår AAT-brist.&lt;br/&gt;&lt;br&gt; I studie I och II hade bristindividerna en statistiskt signifikant högre dödlighet jämfört med svensk befolkning, men överlevnaden var ändå bättre än de tidigare publicerade studierna hade visat. Vi fann också att rökare hade en signifikant högre dödlighet än icke-rökare och svensk befolkning, men icke-rökare som hade identifierats genom screening (hälsoundersökning) hade ingen ökad dödlighet jämfört med svensk befolkning. Emfysem var den viktigaste bakomliggande dödsorsaken både hos rökare och icke-rökare. Dödlighet i skrumplever (levercirros) verkar vara ökad hos äldre icke-rökare; hos 26 av 93 icke-rökare var dödsorsaken cirros och dess komplikationer. Stigande ålder, sjunkande lungfunktion och förekomst av symtom från andningen innebar ökad risk för död hos bristindividerna.&lt;br/&gt;&lt;br&gt; Lungtransplantation (LTX) är indicerat för patienter med svåra lungsjukdomar. Varje år transplanteras cirka 150 patienter med svårt emfysem sekundärt till AAT-brist i hela världen. Tidigare studier har visat att överlevnad efter transplantationen är ungefär samma hos patienter med svår AAT-brist och emfysem och emfysempatienter med normal AAT-halt. Oss veterligen finns inga tidigare publicerade studier som har jämfört överlevnad mellan lungtransplanterade och icke transplanterade patienter med svår AAT-brist. Studie III visade en signifikant överlevnadsvinst för lungtransplantation hos patienter med svår AAT-brist, med en uppskattad medianöverlevnad på 11 år för lungtransplanterade jämfört med 8 år för icke transplanterade bristpatienter. Dessutom verkar remittering till transplantation vara sen i Sverige, vilket kan leda till en onödig ökad dödlighet för denna grupp av patienter.&lt;br/&gt;&lt;br&gt; Ett fåtal studier av syskon med svår AAT-brist har rapporterat att indexfall (den första personen i familjen som fick diagnosen AAT-brist) har svårare KOL, högre rökningsfrekvens och högre förekomst av astma än icke-indexfall. I studie IV har vi inte hittat några signifikanta skillnader i ålder, kön eller rökvanor mellan index- och icke-index syskon. Inte heller fanns det någon signifikant skillnad i lungfunktion vid inklusion. Vår studiepopulation var ganska ung i båda grupperna med en genomsnittlig ålder av 40 år eller yngre och majoriteten av både dem identifierades av screening.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c6da7feb-4648-4b9c-83a1-49c6c4ab17c4</url> </location> </relatedItem> <originInfo> <publisher>Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>lung transplantation</topic> <topic>occupation exposure</topic> <topic>siblings</topic> <topic>smoking</topic> <topic>standardized mortality ratio</topic> <topic>survival.</topic> <topic>causes of death</topic> <topic>alpha-1-antitrypsin deficiency</topic> </subject> <subject authority="lup"> <topic>Respiratory Medicine and Allergy</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-26-0</identifier> <identifier type="oldLupId">2214483</identifier> <part> <detail type="volume"> <number>2011:76</number> </detail> <extent unit="pages"> <total>155</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-09-16T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>c6da7feb-4648-4b9c-83a1-49c6c4ab17c4</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:31:38+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:31:38+02:00</recordDateApproved> </recordInfo> </mods>

Microvascular inflammation, including leukocyte and platelet recruitment as well as epithelial barrier dysfunction, are considered to constitute key components in the pathophysiology of radiation-induced enteropathy. The aim of this thesis was to investigate the basic mechanisms behind leukocyte-platelet-endothelial cell interactions in the colonic microcirculation and intestinal leakage in response to radiotherapy. It was found that immunoneutralization of P-selectin (CD62P) and P-selectin glycoprotein ligand-1 (CD162) abolished radiation-provoked leukocyte and platelet rolling in the colon. Moreover, inhibition of P-selectin and P-selectin glycoprotein ligand-1 also markedly decreased firm adhesion of leukocyte and platelets, suggesting that a rolling adhesive interaction is a prerequisite for subsequent leukocyte and platelet accumulation in response to radiation. However, inhibition of leukocyte and platelet recruitment or systemic depletion of leukocytes and platelets had no impact on radiation-induced intestinal leakage, suggesting that microvascular inflammation does not cause intestinal barrier dysfunction in radiation enteropathy. The role of p38 mitogen-activated protein kinase and Rho-kinase signalling was next examined by use of specific antagonists. Blocking p38 mitogen-activated protein kinase and Rho-kinase activity markedly decreased radiation-induced leukocyte and platelet recruitment in the colonic microvasculature as well as maintained intestinal integrity in response to radiotherapy. Taken together, this thesis elucidates detailed mechanisms regulating microvascular inflammation and intestinal dysfunction in radiation enteropathy. Thus, these findings not only increase our understanding of pathological tissue changes in response to radiotherapy but may also help to develop more effective and specific protective strategies for patients undergoing radiotherapy.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Joniserande strålning används ofta som behandling vid olika tumörsjukdomar i bukhåla&lt;br/&gt;&lt;br&gt; och bäckenregion men är ibland förenad med biverkningar. Dessa kan uppkomma&lt;br/&gt;&lt;br&gt; tidigt/akut, dvs i direkt anslutning till genomförd behandling eller sent, efter månaderår.&lt;br/&gt;&lt;br&gt; Besvären kan vara av mycket varierande och ofta lindrig övergående karaktär såsom&lt;br/&gt;&lt;br&gt; buksmärtor, diarré och blödningar från tarmen. På längre sikt finns det dock risk för&lt;br/&gt;&lt;br&gt; allvarliga biverkningar från tarmen såsom fistelbildning, perforationer samt tarmvred.&lt;br/&gt;&lt;br&gt; Dessa reaktioner medför ibland ett stort och livslångt lidande för de patienter som&lt;br/&gt;&lt;br&gt; drabbas och beror på att delar av tarmen exponerats oavsiktligt i strålfältet. Både de tidiga&lt;br/&gt;&lt;br&gt; och sena biverkningarna anses ha ett nära samband med de akuta inflammatoriska&lt;br/&gt;&lt;br&gt; förändringar eller det vävnadsläckage som äger rum i direkt anslutning till strålbehandlingen.&lt;br/&gt;&lt;br&gt; För att bättre kunna förhindra och behandla dessa biverkningar är det viktigt att&lt;br/&gt;&lt;br&gt; undersöka bakgrunden till och vilka mekanismer som reglerar dessa processer.&lt;br/&gt;&lt;br&gt; Inflammation beskrevs första gången av Celsus för 2000 år sedan som rodnad, svullnad,&lt;br/&gt;&lt;br&gt; värme och smärta vilket är kroppens, och ffa kärlträdets, reaktion på utifrån kommande&lt;br/&gt;&lt;br&gt; stimuli såsom virus, bakterier och trauma i syfte att avgränsa, bekämpa och läka&lt;br/&gt;&lt;br&gt; den uppkomna skadan. Inflammatoriska reaktioner kan också uppstå av andra orsaker&lt;br/&gt;&lt;br&gt; t ex genom att vävnaden exponeras för joniserande strålning. Oavsett initierande agens&lt;br/&gt;&lt;br&gt; har alla inflammatoriska reaktioner vissa basala mekanismer som är gemensamma, t ex&lt;br/&gt;&lt;br&gt; rekrytering av immunceller samt läckage av vätska från blodkärl till drabbad vävnad,&lt;br/&gt;&lt;br&gt; vilka båda anses kunna bidra till ovan beskrivna biverkningar. Rekrytering av vita blodkroppar&lt;br/&gt;&lt;br&gt; (leukocyter) och blodplättar (trombocyter) till det skadade området är en flerstegsprocess&lt;br/&gt;&lt;br&gt; i vilken leukocyter/trombocyter rullar längs kärlväggens endotelceller med&lt;br/&gt;&lt;br&gt; hjälp av en specifik grupp molekyler kallad selektiner. Vidare aktiveras immuncellerna&lt;br/&gt;&lt;br&gt; av kemokiner och fastnar längs kärlväggen varvid leukocyterna sedan kan klämma sig&lt;br/&gt;&lt;br&gt; emellan endotelcellerna och vandra ut i vävnaden för att delta i den uppkomna inflammatoriska&lt;br/&gt;&lt;br&gt; processen till gagn för individen. Det är oklart hur denna process ser ut i&lt;br/&gt;&lt;br&gt; detalj men tidigare publicerade data talar för att både leukocyt/trombocytrekrytering&lt;br/&gt;&lt;br&gt; alternativt endotelcellspåverkan, med efterföljande vävnadsläckage av vätska, kan vara&lt;br/&gt;&lt;br&gt; av betydelse för utvecklingen av sena biverkningar i tarmen. Delarbetena i denna avhandling&lt;br/&gt;&lt;br&gt; belyser några av de mekanismer som reglerar dessa tidiga processer vid strålskada&lt;br/&gt;&lt;br&gt; på tjocktarmen. Vidare klargörs sambandet emellan å ena sidan leukocyt/trombocytrekrytering,&lt;br/&gt;&lt;br&gt; intakt tarmslemhinna och å andra sidan vävnadsläckage, inducerad av joniserande strålning.&lt;br/&gt;&lt;br&gt; Målet med de första och andra delarbetena var att klargöra vilka molekyler som&lt;br/&gt;&lt;br&gt; förmedlar interaktionen mellan såväl leukocyter/trombocyter som mellan endotelceller&lt;br/&gt;&lt;br&gt; på kärlväggen, i strålad tarm. Därtill undersöktes strålningens effekt på vävnadsläckage&lt;br/&gt;&lt;br&gt; då försöksdjuren behandlats med antikroppar mot neutrofila granulocyter (ett slags&lt;br/&gt;&lt;br&gt; leukocyter, vilka anses betydelsefulla i inflammatoriska processer) respektive trombocyter&lt;br/&gt;&lt;br&gt; vilket utlöser neutropeni (brist på vita blodkroppar) respektive trombocytopeni&lt;br/&gt;&lt;br&gt; (brist på trombocyter) i blodet. Djuren bestrålades och efter 16 timmar undersöktes&lt;br/&gt;&lt;br&gt; mikrocirkulationen i tjocktarmen med hjälp av intravitalmikroskopi. Det noterades då&lt;br/&gt;&lt;br&gt; att betydligt flera leuko/trombocyter rullade längs och satt fast (adhererade) på kärlväggen,&lt;br/&gt;&lt;br&gt; vilket tyder på en inflammatorisk reaktion. Djuren förbehandlades med specifika&lt;br/&gt;&lt;br&gt; antikroppar riktade emot P-selektin och PSGL-1 varvid både leuko/trombocytrullning&lt;br/&gt;&lt;br&gt; och leuko/trombocytadhesion minskade betydligt. Vidare noterades att LFA-1, en viktig&lt;br/&gt;&lt;br&gt; adhesionsmolekyl, reglerar leukocytadhesionen i tarmen. Det strålningsinducerade&lt;br/&gt;&lt;br&gt; vävnadsläckaget av vätska befanns vara oberoende av P-selektin, PSGL-1 blockering&lt;br/&gt;&lt;br&gt; och neutro/trombocytopeni.&lt;br/&gt;&lt;br&gt; Yttre stimuli, såsom osmotisk chock, bakteriegifter samt joniserande strålning aktiverar&lt;br/&gt;&lt;br&gt; intracellulära signalsystem i olika vävnader. Ett av dessa system, p38 MAPK, har&lt;br/&gt;&lt;br&gt; visat sig vara viktigt för reglering av genöverföring, utmognad och protein tillverkning&lt;br/&gt;&lt;br&gt; för vävnadens integritet och överlevnad. SB 239063 är en drog som har visat sig vara&lt;br/&gt;&lt;br&gt; en potent hämmare av p38 MAPK-aktivitet vilket studerades i det tredje arbetet. Då&lt;br/&gt;&lt;br&gt; SB 239063 gavs till djuren, före bestrålning, noterades att både leuko/trombocytrullning&lt;br/&gt;&lt;br&gt; respektive adhesion markant minskade. Därtill noterades även en minskning av&lt;br/&gt;&lt;br&gt; MPO-aktiviteten, ett mått på förekomst av neutrofila granulocyter, i vävnaden. De vid&lt;br/&gt;&lt;br&gt; leukocytrekrytering viktiga signalsubstanserna MIP-2 och KC, samt vätskeutträdet till&lt;br/&gt;&lt;br&gt; vävnaden, minskade. Detta tyder på att bibehållen tarmintegritet är en viktig komponent&lt;br/&gt;&lt;br&gt; för att förhindra vävnadsläckage.&lt;br/&gt;&lt;br&gt; Rho-kinaser är en familj av proteiner vilka anses vara viktiga för eukaryota cellers&lt;br/&gt;&lt;br&gt; rörlighet och adhesionsmöjligheter. I det fjärde arbetet förbehandlades försöksdjuren&lt;br/&gt;&lt;br&gt; med Y27632, en hämmare av Rho-aktivitet, vilket resulterade i minskad leuko/trombocyt&lt;br/&gt;&lt;br&gt; rekrytering och lägre MPO/MIP-2/KC nivåer i vävnaden. Slutligen noterades en&lt;br/&gt;&lt;br&gt; betydande reduktion av vävnadsläckaget.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis beskrivs i denna avhandling viktiga mekanismer vilka reglerar&lt;br/&gt;&lt;br&gt; leuko- och trombocytrekrytering samt vävnadsläckage vid exponering för joniserande&lt;br/&gt;&lt;br&gt; strålning. Den har visat att strålnings framkallad leuko/trombocytrullning är P-selektin&lt;br/&gt;&lt;br&gt; och PSGL-1-beroende samt LFA-1 reglerar leukocytadhesion i tjocktarmen. Interferens&lt;br/&gt;&lt;br&gt; med p38-MAPK och Rho-kinas aktivitet skyddade emot leuko- trombocytrekrytering,&lt;br/&gt;&lt;br&gt; minskade MPO-aktivitet samt tjocktarmens innehåll av de viktiga signalmolekylerna&lt;br/&gt;&lt;br&gt; MIP-2 och KC. I detta arbete visas också att vävnadsläckaget inte är beroende av det&lt;br/&gt;&lt;br&gt; inflammatoriska vävnadssvaret, dvs leuko/trombocytrekrytering, utan är snarare beroende&lt;br/&gt;&lt;br&gt; av bibehållen integritet i vävnaden. Resultaten i denna avhandling kan bidra till&lt;br/&gt;&lt;br&gt; förståelse för de mekanismer som orsakar strålskada i tarmen, syftandes till att i framtiden&lt;br/&gt;&lt;br&gt; kunna skydda patienter mot allvarliga biverkningar orsakad av strålbehandling.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c1ca286a-ff52-4ac4-82f3-95523c404f7e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Andrada__Rome_kappa.pdf">https://portal.research.lu.se/files/3431233/1716841.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5196856</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>radiation</topic> <topic>colon</topic> <topic>intestinal leakage</topic> <topic>Leukocyte and platelet recruitment</topic> </subject> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-52-5</identifier> <identifier type="oldLupId">1716628</identifier> <part> <detail type="volume"> <number>2010:136</number> </detail> <extent unit="pages"> <total>130</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-12-09T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>c1ca286a-ff52-4ac4-82f3-95523c404f7e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:31:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:31:41+02:00</recordDateApproved> </recordInfo> </mods>

This thesis contributes to the development of robot concepts that fit the needs of SMEs. A major part of the thesis deals with the modeling of the three degree-of-freedom (DOF) Gantry-Tau parallel kinematic robot, which has the potential to fulfill the requirements on accuracy, mechanical stiffness and conceptual flexibility of a robot for SMEs. Additionally, concepts that aid the SMEs to achieve the required accuracy and a more intuitive robot operation were developed and evaluated. The modeling of the Gantry-Tau robot includes both kinematic and dynamic modeling. Based on the nominal kinematic model, kinematic error models were developed, as well as kinematics for the F1-type Gantry-Tau, a Gantry-Tau architecture extended to 6~DOF. The modeling was evaluated in kinematic calibration experiments. A rigid body model was derived and identified, including friction in the actuators. As noticeable flexible behaviour was observed, the compliance dynamics were identified by black box modeling. Kinematic calibration was not only considered for evaluation of the kinematic models developed, but it was also studied how to automize the kinematic calibration procedure, so that it can be executed by non-expert SME staff after a possible geometric reconfiguration of the robot. In the search of affordable, accurate and reusable measurement devices for kinematic calibration in SMEs, the usage of camera vision for kinematic calibration was evaluated. To make the programming of a robot trajectory fast and intuitive, lead-through programming was recently introduced. A new concept for lead-through programming in contact situations is proposed in this thesis, where two force sensors are used. While the first sensor is used for guiding the robot, the second force sensor measures the tool force, which can prevent damage of the tool or workpiece and can help to keep a steady contact between tool and surface. The concept was demonstrated in two example applications. A possibility to improve the performance for a repeatedly executed motion is iterative learning control (ILC). An ILC algorithm is evaluated on the Gantry-Tau robot, which uses an estimate of the tool motion, based on measurements from an accelerometer mounted at the end-effector plate and in addition to measurements on the motor side. The performance of the tool motion was shown to be considerably improved compared to the case when only motor side measurements are used.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Made in China - På hur många av dina barns leksaker står det? Produktionen inom många sektorer flyttas från Europa till länder där arbetskraften är billigare. Forskningen i avhandlingen &quot;Modeling and Control of Stiff Robots for Flexible Manufacturing&quot; ska hjälpa europeiska småföretag att bli mer konkurrenskraftiga och samtidigt underlätta för arbetarna. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Högt ljud från olika maskiner i hela hallen, värme från gjutningen och metalldamm i luften. I denna miljö slipar arbetaren av överflödigt material från tunga pumphus. Hur bra vore det då att kunna stå vid sidan och titta på hur det görs helt av sig själv? Med hjälp av forskningen presenterad i denna avhandling och en ny sorts robot kan drömmen bli verklighet. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den nya roboten ska inte ersätta arbetaren, men göra det tunga arbetet åt honom/henne, snabbare och noggrannare, medan arbetaren ``leder&apos;&apos; roboten genom hela processen. Operatören monterar en slipmaskin på roboten och tar maskinen i handen för att beskriva banan roboten ska gå genom.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Men innan man kan lära en robot att samverka på detta sätt med människor, behöver man en robot som lämpar sig för användningen i småföretag. Den måste vara billig nog att passa in i företagens budget. Metall- och träbearbetning, som ofta utförs i småföretag, kräver en styvare och noggrannare robotstruktur än till exempel en paketeringsrobot i ett storföretag. Och eftersom småföretag ofta tillverkar ett mindre antal av samma produkt än stora företag, måste roboten vara flexibel och passa till varierande uppgifter och ibland även varierande produktstorlek.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Gantry-Tau roboten kan vara lösningen för småföretag. Den har en parallell struktur, vilket betyder att verktyget, till exempel en slipmaskin, hålls av flera armar parallellt. Den klassiska industriroboten har bara en arm och kallas därför för seriell robot. Konstruktionen med tre armar gör roboten styvare än vanliga seriella robotar. Mindre massa krävs för att göra strukturen styv, vilket leder till lägre materialkostnad. Gantry-Tau roboten består av ett justerbart ramverk och tre armar fästa på en platta som håller verktyget. På ramverket sitter tre spår med vagnar som tillsammans håller verktyget i andra änden av armarna. Genom att flytta på vagnarna kan man röra armarna och därmed också verktygsplattan, där t.ex. slipmaskinen sitter. Genom att justera ramverket kan man enkelt anpassa roboten till en ny produkt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; För att kunna köra roboten, behöver man en beskrivning av robotens dimensioner. Det kallas inom robotik för kinematisk modell. Om man vill att slipmaskinen ska befinna sig på en viss position, måste man veta hur vagnarna ska röras. Ju noggrannare man vet kinematikmodellen, desto noggrannare kan man placera slipmaskinen eller något annat verktyg. En dålig kinematikmodell kan leda till att man slipar av för mycket material eller att en svetsning placeras utanför svetsfogen, för att roboten rör sig snett istället för rakt.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det finns två problem att lösa här: Att mäta robotens verkliga dimensioner, men också att veta de matematiska ekvationer som beskriver hur man räknar mellan vagn- och verktygsposition. Ekvationerna är samma oavsett om man byter ut ett stag till ett längre eller flyttar ett av spåren. Men ibland tillverkas roboten inte så noggrant som tänkt, eller så kanske ett spår sitter lite skevt efter en justering. I avhandlingen har ekvationer utvecklats som kan ta hand om sådana små fel, så att robotens noggrannhet inte försämras.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den intuitivt enklaste metoden att bestämma robotens dimensioner är nog att ta en stor linjal och mäta upp längderna för hand. Men ramverket kan vara upp till två meter högt medan avstånden på verktygsplattan är några centimeter. En sådan manuell mätning kan aldrig ge den millimeternoggranhet som är nödvändig. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Därför väljer man ett annat sätt, som undersökts i denna avhandling. Vagnpositionerna mäts mycket noggrant för att kunna positionera vagnen exakt. För att bestämma kinematikmodellen kör man roboten till ett antal positioner och mäter för varje punkt verktygets tredimensionella position och vagnarnas position på spåret. Därefter optimerar man den kinematiska modellen tills man får minsta möjliga fel mellan uträknade och uppmätta positioner. Denna procedur kallas för kinematisk kalibrering. För att uppnå en bra kalibrering är det viktigt att ta tillräckligt många mätningar, välja mätpunkterna på ett bra sätt och ha ett noggrant mätinstrument.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I avhandlingen betraktas flera aspekter av kinematisk kalibrering. Med hjälp av de nya, noggrannare matematiska ekvationerna undersöks hur noggrant man kan placera robotens verktyg. Men vi får också tänka på arbetaren i gjuteriet. Han har kanske just avslutat en serie pumphus, och nu behöver han justera robotens ramverk för att kunna bearbeta en större pumphusmodell. Genom att förändra ramverket förändrar han också robotens dimensioner. Han behöver alltså bestämma robotens nya dimensioner med kinematisk kalibrering innan han kan använda roboten igen. Problemet är att han inte vet de bästa robotställningar för mätningen eller hur man optimerar robotbeskrivningen med mätningarna. Inte heller har ett småföretag råd att betala en robotexpert varje gång roboten ska ändras.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Avhandlingen har tagit fram och undersökt en automatiserad metod för kinematisk kalibrering, där ett datorprogram tar hand om hela processen, och operatören behöver bara sätta igång den. Den kinematiska kalibrering som genomförs med programmet är lika noggrann som kalibreringar av robotexperter. Avhandlingen har också undersökt hur digitalkameror kan användas som ett billigt, men mindre noggrant mätinstrument till kinematisk kalibrering. Istället för slipmaskinen sätter man en platta med schackbrädesmönster på verktygsplattan och tar ett kort av roboten för varje mätpunkt. Genom att jämföra det verkliga mönstrets storlek med bilden kan man räkna ut var verktygsplattan befinner sig.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Kinematikmodellen är viktig för att kunna röra roboten, men den beskriver inte roboten lika noggrant när den rör sig snabbt och kanske stagen böjer sig lite med rörelsen. Inte heller beskriver den hur mycket kraft man behöver för att röra roboten. Det görs i en dynamisk modell. Avhandlingen undersöker robotens dynamik och tar fram olika modeller, som är viktiga när man vill röra roboten snabbt och ändå noggrant.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Nu när den nya roboten är färdig att användas, behöver operatören lite hjälp med att få roboten att utföra den önskade uppgiften. Oftast sker det idag med en uppgiftsbeskrivning i ett specifikt robotspråk som innehåller kommandon för hur roboten ska röra sig. Det tar mycket tid, är inte intuitivt, och man måste kunna språket. Därför har ett enklare alternativ, s.k. lead-through programming, testats i avhandlingen. Här tar man tag i roboten med sin engen hand och leder verktyget längs den önskade banan. Roboten känner av trycket från operatörens hand genom en kraftsensor. Det nya med metoden som presenteras i avhandlingen är att man använder två kraftsensorer. Den ena känner av trycket från handen och styr roboten i den önskade riktningen. Den andra känner av kraften mellan roboten och ett arbetsstycke, till exempel ett pumphus, och hjälper till att hålla ett konstant tryck mot arbetsstycket, så att man inte skadar verktyget eller förlorar kontakten.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Iterativ inlärning har också testats med Gantry-Tau-roboten. Med iterativ inlärning menas att man förbättrar robotens prestanda successivt genom att mäta skillnaden mellan den önskade och den faktiska rörelsen som roboten gör. Man ändrar rörelsen av motorerna gång efter gång tills man uppnår den önskade precisionen. Trots att det är verktyget som ska röra sig på en viss bana utför man oftast iterativ inlärning baserad på vagnrörelsen eftersom det är svårt att mäta verktygspositionen i ett industriell sammanhang utan att störa tilllämpningen. I avhandlingen undersöks en ny metod som skattar verktygsrörelsen med hjälp av en sensor på verktygsplattan som mäter accelerationen. I testerna uppnås en tydlig förbättring av precisionen för iterativ inlärning jämfört med den vanliga metoden.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Forskningen som presenteras i avhandlingen öppnar vägen mot att robotar kan även användas i småföretag. Slipmaskinen i examplen ovan kan bytas mot andra verktyg. Roboten kan göra arbetet enklare och samtidigt öka produktivitet och kvalitet, vilket gör företagen mer konkurrenskraftiga.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f3dc5c26-e964-4417-a3fb-45e7bab0d6b8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thesis_final.pdf">https://portal.research.lu.se/files/3431307/2970881.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7365460</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Automatic Control, Lund Institute of Technology, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Control Engineering</topic> </subject> <relatedItem type="host"> <titleInfo> <title>PhD Thesis TFRT-1093</title> </titleInfo> <identifier type="issn">0280-5316</identifier> <identifier type="issn">0280-5316</identifier> <identifier type="oldLupId">2970871</identifier> <part> <extent unit="pages"> <total>206</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popscienceFlexibla robotar för konkurrenskraftig tillverkning.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3431305/2970883.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-09-07T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>f3dc5c26-e964-4417-a3fb-45e7bab0d6b8</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:31:42+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:31:42+02:00</recordDateApproved> </recordInfo> </mods>

Deterioration of concrete structure is in most cases caused by the penetration of aggressive media from the surrounding environment. Chloride initiated&lt;br/&gt;&lt;br&gt; reinforcement corrosion is one of the major causes of deterioration of concrete structures. One conflicting issue is how replacing Portland cement with mineral additions influences chloride initiated reinforcement corrosion. This issue is of immediate interest, as there is a steady growth in the use of cement blended with mineral additions, such as blast-furnace slag, fly ash and limestone filler. This is done by the cement and concrete industry to reduce the CO2 emissions linked to Portland cement manufacturing, by limiting the use of clinker in the cement.&lt;br/&gt;&lt;br&gt; The main objective of this work has been to further clarify the role of limestone filler as partial substitute to Portland cement on the two main decisive parameters for chloride induced reinforcement corrosion: chloride ingress rate and chloride threshold values. In the first part of this work the chloride ingress was studied both with accelerated laboratory methods and also after field exposure. The initial focus for the second part of the study was to determine the&lt;br/&gt;&lt;br&gt; chloride threshold values for the binders investigated in the first part, so a comprehensive view of the effect of limestone addition on chloride initiated corrosion could be presented. However,during the work the need for the development of a practice-related method for determining the chloride threshold values was identified and the focus of the research was redirected to meet that need. The efficiency of limestone filler concerning chloride ingress showed to be dependent on&lt;br/&gt;&lt;br&gt; replacement ratio, time (age) and on the test method. It was not possible to draw any rigid conclusion of the limestone filler’s efficiency regarding chloride ingress. But part of the inconsistency in the results was identified to be that limestone filler has two opposite effects on chloride ingress, on one hand contribute to a refinement of microstructure and on the other hand diminishing the chloride binding. &lt;br/&gt;&lt;br&gt; The steel surface condition was shown to have a strong effect on the corrosion initiation, and can likely be one of the most decisive parameters attributing to the variability in the reported&lt;br/&gt;&lt;br&gt; chloride threshold values obtained in laboratory experiments. The chloride threshold value for the sulphate resistant Portland cement from the laboratory experiments was estimated to be about 1% by weight of binder. For the concrete with limestone blended cement (CEM II/A-LL&lt;br/&gt;&lt;br&gt; 42.5R) tested in this work the chloride threshold value was at the same level as for the sulphate resistant Portland cement. From the field study but with a somewhat different definition of chloride threshold value, a chloride threshold value of about 1% by weight of binder was also estimated for ordinary Portland cement and sulphate resistance Portland with 5% silica fume exposed to marine environment.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/fc7511de-f7fb-482f-8ffa-806e875c931a</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Spikad_version_20160218.pdf">https://portal.research.lu.se/files/3432294/8726348.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2198590</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University Division of Building Materials Faculty of Engeering</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Concrete</topic> <topic>cement</topic> <topic>limestone filler</topic> <topic>chloride ingress</topic> <topic>chloride threshold values</topic> </subject> <subject authority="lup"> <topic>Other Materials Engineering</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">8726302</identifier> <part> <extent unit="pages"> <total>86</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-03-18T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>fc7511de-f7fb-482f-8ffa-806e875c931a</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:31:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:31:53+02:00</recordDateApproved> </recordInfo> </mods>

The order of the objective function is defined as the highest number of arguments of any summand. To reduce ambiguity and noise in the solution, regularization terms are included into the objective function, enforcing different properties of the solution. The most commonly used regularization is penalization of boundary length, which requires a second-order objective function. Most of this thesis is devoted to introducing higher-order regularization terms and presenting efficient minimization schemes.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; One of the topics of the thesis covers a reformulation of a large class of discrete functions into an equivalent form. The reformulation is shown, both in theory and practical experiments, to be advantageous for higher-order regularization models based on curvature and second-order derivatives. Another topic is the parametric max-flow problem. An analysis is given, showing its inherent limitations for large-scale problems which are common in computer vision. The thesis also introduces a segmentation approach for finding thin and elongated structures in 3D volumes. Using a line-graph formulation, it is shown how to efficiently regularize with respect to higher-order differential geometric properties such as curvature and torsion. Furthermore, an efficient optimization approach for a multi-region model is presented which, in addition to standard regularization, is able to enforce geometric constraints such as inclusion or exclusion of different regions. The final part of the thesis deals with dense stereo estimation. A new regularization model is introduced, penalizing the second-order derivatives of a depth or disparity map. Compared to previous second-order approaches to dense stereo estimation, the new regularization model is shown to be more easily optimized.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Inom många områden, exempelvis inom sjukvården, blir det allt vanligare med situationer där stora mängder av bilder behöver analyseras. Ofta kan dessa bildmängder vara så stora att det tar för lång tid för en människa att gå igenom dem. Till exempel kan man med hjälp av datortomografi ta tredimensionella röntgenbilder av människor, något som görs på sjukhus idag. Att gå igenom dessa bilder manuellt tar givetvis massor av resurser från läkare, resurser som skulle kunna användas bättre.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Ett av målen med datorseende är att automatisera analysen av stora bildmängder. Ett av de första stegen när man analyserar en bild automatiskt är ofta att rita ut gränser mellan olika objekt, att segmentera bilden i olika områden. När man ska göra en sådan segmentering så brukar man bygga upp en statistisk modell som säger att varje pixel i bilden med en viss sannolikhet tillhör ett visst objekt, exempelvis en lunga eller benmärgen. &lt;br/&gt;&lt;br&gt; Segmenteringen väljs sedan så att varje pixel får tillhörighet till det objekt som har högst sannolikhet i just den pixeln. Problemet är dock att varken modellen eller bilderna är perfekta och de resulterande segmenteringarna är ofta brusiga. Ett sätt att minska detta problem är att införa mer regler i modellen. För de flesta bilder är det till exempel troligt att pixlar som ligger nära varandra tillhör samma objekt. Att lägga in sådana regler i modellen brukar kallas att regularisera lösningen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Regularisering kan även användas vid automatisk generering av så kallade djupkartor. I en djupkarta anges avståndet till varje objekt i en bild.&lt;br/&gt;&lt;br&gt; Djupkartor är exempelvis användbara inom spelindustrin. Med hjälp av djupkartor kan man till exempel mäta en hands rörelser och på så sett använda kroppen som en handkontroll. I automatiskt genererade djupkartor finns ofta brus som man kan minska med hjälp av regularisering. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; En lägre ordningens regularisering innebär att man inför krav på storheter som man kan uppskatta utifrån två punkter, exempelvis längden på en kurva. I en högre ordningens regularisering inför man krav på storheter som kräver fler än två punkter. Ett exempel på en sådan storhet är en kurvas krökning.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Denna avhandling omfattar i huvudsak olika modeller för automatisk bildsegmentering och uppskattning av djupkartor. För de olika modellerna införs högre ordningens regulariseringsmodeller och det visas hur man effektivt hittar bra lösningar till dessa modeller.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/5daf1988-f2dd-43c3-aa8c-229436009312</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="ulen-phd-14.pdf">https://portal.research.lu.se/files/3434314/4862875.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">17343365</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Centre for Mathematical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Computer Vision</topic> <topic>Regularization</topic> <topic>Segmentation</topic> <topic>Dense Stereo</topic> </subject> <subject authority="lup"> <topic>Computer graphics and computer vision</topic> <topic>Mathematical Sciences</topic> </subject> <relatedItem type="host"> <location> <url>http://www.maths.lth.se/~ulen/thesis.pdf</url> </location> </relatedItem> <relatedItem type="host"> <identifier type="isbn">978-91-7623-163-0 (print)</identifier> <identifier type="isbn">978-91-7623-164-7</identifier> <identifier type="oldLupId">4777619</identifier> <part> <extent unit="pages"> <total>225</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-12-11T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>5daf1988-f2dd-43c3-aa8c-229436009312</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:11+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2026-02-13T10:48:46Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:11+02:00</recordDateApproved> </recordInfo> </mods>

Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels. Using natural gas/biogas can be a very good alternative due to the attractive fuel properties regarding emission reduction and engine operation. &lt;br/&gt;&lt;br&gt; Heavy-duty diesel engines can be easily converted for natural gas operation which is a very cost effective process for producing gas engines. However, due to the high throttle losses and low expansion ratio the overall engine efficiency is lower than the corresponding diesel engines. Moreover the lower density of natural gas results in lower maximum power level.&lt;br/&gt;&lt;br&gt; In this thesis key features and strategies which may result in improved efficiency, increased maximum power and improved transient capability of a heavy-duty natural gas engines have been identified, validated and suggested. &lt;br/&gt;&lt;br&gt; High EGR rates combined with turbocharging has been identified as a promising way to increase the maximum load and efficiency of heavy-duty gas engines. With stoichiometric conditions a three way catalyst can be used and thus regulated emissions can be kept at very low levels. Obtaining reliable spark ignition is difficult however with high dilution and there will be a limit to the amount of EGR that can be tolerated for each operating point.&lt;br/&gt;&lt;br&gt; Extending the dilution limit of the engine and developing closed-loop control to operate the engine at its dilution limit has been the main method to reduce throttle losses. A new method for calculating cyclic variation was developed that significantly improved the transient capability of the engine control system. The method consequently applied on a closed-loop dilution limit control. Only applying closed-loop control to operate the engine at its dilution limit resulted in at least 4.5% improvement in specific fuel consumption at 1200 RPM. The dilution limit can also be extended by replacing the combustion chambers with high turbulence pistons which enhances the combustion. By extending the dilution limit the gain in efficiency will be even higher. &lt;br/&gt;&lt;br&gt; In summary the key features to improve the performance of a stoichiometrically operated natural gas engine are identified as: right amount of EGR at different operating regions, right compression ratio, Variable Geometry Turbocharger (VGT), high turbulence pistons, long route EGR system and model-based control.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; News about global warming, discussions about alternative fuels such as natural-gas and biogas, and commercials about gas engines sound familiar to the most people living in modern societies.&lt;br/&gt;&lt;br&gt; Why global warming is important? What is the role of natural-gas engines in this subject? Are natural-gas engines efficient? Do they perform as well as diesel engines? If not, why? How can they be optimized? In the following two pages it is tried to answer very briefly to these questions. In this paper focus is on heavy-duty (i.e. medium size) natural-gas engines and not light-duty.&lt;br/&gt;&lt;br&gt; World energy consumption is expected to increase by 50 percent over the next 20 years. The transportation sector is the biggest sector in liquid fuel consumption. Road transportation is the main part in the transportation sector. The fuels mainly used in internal combustion engines are petroleum products i.e. gasoline and diesel. This information is collected from Energy Information Administration report from 2005.&lt;br/&gt;&lt;br&gt; Fossil fuels are of great importance since burning them produces significant amounts of energy, but they have a great impact on the environment due to the Carbon-Dioxide (i.e. CO2) production. CO2 is a strong greenhouse gas that contributes to the climate change which is an issue of growing international concern. Besides that, the local impact of other pollutants i.e. NOX and PM for diesel engines is a big issue.&lt;br/&gt;&lt;br&gt; To reduce these impacts emission regulation were introduced in the mid-nineteenth century. The regulation has been becoming very sever which has been resulted in very pricey catalysts.&lt;br/&gt;&lt;br&gt; Demand for lower pollutant levels together with increasing concern for climate changes force engine developers to find and investigate more efficient alternative engine management. Using alternative fuels such as natural-gas is one of the attractive solutions for engine application due to several facts. Natural-gas produces less CO2 since it has less carbon atoms. The CO2 reduction is much more if biogas is used. The availability and its high knock resistance are some other properties which make it attractive as engine fuel. However, heavy-duty natural-gas engines produce lower maximum torque than the corresponding diesel engines due to the lower density.&lt;br/&gt;&lt;br&gt; Normally natural-gas engines use same combustion technology as gasoline engines due to the similar fuel properties. Natural-gas engines can be operated in different modes. Lund University has been researching about heavy-duty natural-gas engine since 1990.&lt;br/&gt;&lt;br&gt; This project focuses on stoichiometric1&lt;br/&gt;&lt;br&gt; 1 Stoichiometric is the ideal combustion process where fuel is burned completely. operation. By operating engine in this mode good engine performance can be obtained&lt;br/&gt;&lt;br&gt; and a cost effective 3-way catalyst can be used to reduce all emissions simultaneously.&lt;br/&gt;&lt;br&gt; The main objective of this project is to explore the reasons for the lower performance of natural-gas engine and develop relevant strategies to recover them. The developed strategies will be consequently validated by performing experiments in a test cell. A multi-cylinder 9.4 liter engine from Volvo was used for experiments (see Figure 1).&lt;br/&gt;&lt;br&gt; Figure 1 Engine setup structure. A Linux based PC used to control ignition and injection&lt;br/&gt;&lt;br&gt; The available heavy-duty natural-gas engines are generally diesel engines which converted for natural-gas operation. Due to that the engines are limited to some limitations.&lt;br/&gt;&lt;br&gt; Heavy-duty natural-gas engines suffer from lower efficiency in compare with a corresponding diesel engine. There are mainly two reasons for that; first the lower compression ratio which is limited due to knock phenomena and second, the use of throttle for controlling the desired torque which introduces lots of pumping losses into the engine.&lt;br/&gt;&lt;br&gt; Exhaust Gas Recirculation (EGR) can be used to minimize the throttling losses. The addition of inert exhaust gas into the intake system means that for a given power output, the throttle plate must be opened further, resulting in increased inlet manifold pressure and reduced throttling losses (see Figure 2).&lt;br/&gt;&lt;br&gt; Figure 2 Adding EGR means that for a given power output, the throttle plate must be opened further which results in lower throttle losses&lt;br/&gt;&lt;br&gt; By keeping the EGR effect in mind it is desired to operate the engine with the highest possible EGR rate (i.e. dilution limit). The dilution limit is imposed by increased cyclic variation of the combustion intensity that reduces the drivability. It can be improved by closed loop control of EGR based on combustion stability.&lt;br/&gt;&lt;br&gt; The experimental results show at least 5% reduction in fuel consumption can be achieved which is significant. Moreover; implementing small modifications on the engine resulted in more efficiency improvement and maximum load extension. These modifications are applied on engine pistons, turbocharging system and EGR system.&lt;br/&gt;&lt;br&gt; Finally it can be concluded that, there is a lot of space for improvement and optimization of the stoichiometric natural-gas engines. Our results showed by implementing simple modifications and designing simple regulators efficiency can be increased drastically.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7d1c54ac-1102-4327-9f9f-44c4d111730c</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Doctoral_Thesis_Mehrzad_Kaiadi.pdf">https://portal.research.lu.se/files/3434743/1762733.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2286809</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Tryckeriet i E-huset, Lunds universitet</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Turbulence</topic> <topic>Natural gas engine</topic> <topic>Dilution limit</topic> <topic>VGT</topic> <topic>Cyclic variation</topic> <topic>Closed-loop control</topic> <topic>Heavy-duty</topic> </subject> <subject authority="lup"> <topic>Other Mechanical Engineering</topic> </subject> <relatedItem type="host"> <identifier type="oldLupId">1762706</identifier> <part> <extent unit="pages"> <total>109</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-02-11T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>7d1c54ac-1102-4327-9f9f-44c4d111730c</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:17+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:17+02:00</recordDateApproved> </recordInfo> </mods>

Paper I focuses on differentially expressed microRNAs in ccRCC. We used bioinformatics methods to identify candidate microRNAs in a publically available cohort of ccRCC, which were measured in a cohort of 198 RCC tumors. Importantly, we identified a 2-microRNA ratio, miR(21/10b), which is an independent prognostic factor in metastasis-free ccRCC patients. These microRNAs are both linked to chronic kidney disease, a risk factor for ccRCC, and could potentially be involved in the progression from kidney disease to renal cancer. In Paper II, our aim was to elucidate if members of the miR-34 family, which is a family of microRNA tumor suppressors, could regulate Axl in ccRCC, and also to determine miR-34a/b/c expression in ccRCC tumors, as reports have been conflicting. Axl has previously been shown to be a target of miR-34a in solid cancers, and high Axl expression correlates with worsened prognosis in RCC. We showed that both miR-34a and miR-34c are direct regulators of Axl in vitro, however miR-34a expression is increased in ccRCC and does not correlate with Axl mRNA or protein in ccRCC tumors, and has no correlation with survival in ccRCC. Paper III was aimed at elucidating whether any of the miR-34 family members could regulate Axl expression PCa, as both miR-34a and miR-34c are downregulated in PCa, and Axl expression is increased in PCa and correlates with disease severity. In addition, we sought to elucidate the role of decreased Axl expression in miR-34a/c-mediated tumor suppression. Although we could show direct regulation of Axl by miR-34a and miR-34c, our results did not support regulation of Axl as the main function in miR-34a/c tumor suppression in PCa. The main functional outcome of miR-34a/c-mediated loss of Axl seemed to be in reduced proliferation in response to Gas6. Finally, paper IV has the aim of investigating the role of Gas6/Axl signaling in Sunitinib treatment in ccRCC. Axl has been linked to resistance to targeted therapies in cancer. Sunitinib is an angiogenesis-inhibiting drug used in treatment of advanced ccRCC, however disease progression eventually occurs in many patients. We show that Sunitinib does not inhibit Axl activation by Gas6; instead Axl phosphorylation was enhanced in the presence of Gas6 and Sunitinib, both in ccRCC cells and in endothelial cells. Moreover, we observed activation of Akt pathway in Sunitinib-treated cells, which was enhanced by the addition of Gas6. In addition Sunitinib activated the epidermal and hepatocyte growth factor receptors, an effect that was augmented by Gas6. Interestingly, Gas6 stimulation was associated with secretion of Osteopontin, associated with tumor angiogenesis, an effect that was increased by Sunitinib.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/baa7701a-db09-4480-a248-37031c78f560</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling.pdf">https://portal.research.lu.se/files/3435302/5366247.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2126977</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Translational Medicine</publisher> <dateIssued encoding="w3cdtf">2015</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Medicinal Chemistry</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-142-2</identifier> <identifier type="oldLupId">5366241</identifier> <part> <detail type="volume"> <number>2015:63</number> </detail> <extent unit="pages"> <total>218</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2015-05-28T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>baa7701a-db09-4480-a248-37031c78f560</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:24+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:24+02:00</recordDateApproved> </recordInfo> </mods>

Optimization models&lt;br/&gt;&lt;br&gt; underlying such tools are developed in this thesis. We study a number of single and two-layer core network design problems defined as mathematical programmes, focusing on fair bandwidth allocation among demands, recovery mechanisms, and load balancing on network links.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Assuming elastic traffic, fair allocation of network bandwidth among the users is not trivial since different users may have different preferences and requirements for minimum bandwidth. We study single and two layer network dimensioning tasks where elastic and non-elastic&lt;br/&gt;&lt;br&gt; demands are combined, and investigate different fairness principles, with special attention devoted to proportional fairness. The models are developed for designing the networks for the normal state of network&lt;br/&gt;&lt;br&gt; operation, as well as for failure states.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; For the two-layer problems it is not at all clear in which layer the recovery should be performed, and what recovery mechanisms to use. Therefore, recovery aspects in different layers are studied and models are provided for different recovery mechanisms. Furthermore, a generic resolution framework and heuristic algorithms for the selected&lt;br/&gt;&lt;br&gt; dimensioning and allocation problems in two-layer networks are developed.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Balancing of load on network links decreases probability of rejection of future requests due to shortage of resources in some parts of the network. In the thesis different load balancing options are discussed, and an integrated routing, recovery, and load balancing strategy is developed.

To&lt;br/&gt;&lt;br&gt; prevent rejection immunosuppresive treatment must be maintained lifelong, unless transplantation is&lt;br/&gt;&lt;br&gt; perfomed between identical twins. Many immunosuppresive agents introduced in clinical practice have&lt;br/&gt;&lt;br&gt; been benificial in improving graft survival rates, but adverse effects remains a huge problem together&lt;br/&gt;&lt;br&gt; with late loss of grafts. There is a need for improved medical strategies. In search for immunosuppressive&lt;br/&gt;&lt;br&gt; drugs, monocarboxylate transporter (MCT1) inhibitors were identified and in vitro studies&lt;br/&gt;&lt;br&gt; revealed a marked inhibibition of the immune response by the compound. Blockage of costimulatory&lt;br/&gt;&lt;br&gt; pathways is another alternative that has been explored during the past few years.&lt;br/&gt;&lt;br&gt; The aim of this study was to evaluate the immunological response in terms of graft survival, histological&lt;br/&gt;&lt;br&gt; evidence of inflammatory response, toxicity and drug administration of costimulatory antibodies and&lt;br/&gt;&lt;br&gt; the new immunomodulatory compounds, MCT1 inhibitors, in cardiac-, skin- and pancreatic islet&lt;br/&gt;&lt;br&gt; transplantation models in rodents.&lt;br/&gt;&lt;br&gt; The results show that in costimulatory blockade the combination of two or three antibodies, anti-&lt;br/&gt;&lt;br&gt; CD40L, CTLA4Ig and anti-LFA-1, resulted in indefinite graft survival of allogenic islets transplanted in&lt;br/&gt;&lt;br&gt; mice and that the combination of anti-CD40L and CTLA4Ig totally prevented the rejection and&lt;br/&gt;&lt;br&gt; histological signs of islet destruction. The new compounds, MCT1 inhibitors, did induce indefinite graft&lt;br/&gt;&lt;br&gt; survival in allograft transplantation models in the rat. The MCT1 inhibitor AR-C117977 showed the&lt;br/&gt;&lt;br&gt; best graft survival rates out of seven different analogues and was therefore evaluated in more&lt;br/&gt;&lt;br&gt; challenging models like skin- and cardiac xenotransplantation. The limitations for this compound were&lt;br/&gt;&lt;br&gt; transplantation to rats already sensitised with preformed antibodies. We could still demonstrate, in&lt;br/&gt;&lt;br&gt; addition to suppression of T-cell proliferation, that this compound also had a suppressive effect on Bcells&lt;br/&gt;&lt;br&gt; and antibody production.&lt;br/&gt;&lt;br&gt; In conclusion MCT1 inhibitors demonstrated promising results of immunosuppressive properties and&lt;br/&gt;&lt;br&gt; graft survival in different transplantation models. Further developments of MCT1 inhibition have the&lt;br/&gt;&lt;br&gt; potential to give a positive contribution to the treatment used in clinic practice in transplanted patients&lt;br/&gt;&lt;br&gt; in the future.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; För att ett transplanterat organ ska accepteras av mottagaren behövs&lt;br/&gt;&lt;br&gt; immunhämmande läkemedel. Dessa läkemedel dämpar immunförsvaret och&lt;br/&gt;&lt;br&gt; förhindrar avstötning av det transplanterade organet. Immunförsvaret har olika sätt att angripa organet, som det uppfattar som kropps-främmande.&lt;br/&gt;&lt;br&gt; Idag används olika läkemedel i kombination som behandling mot avstötning.&lt;br/&gt;&lt;br&gt; Tyvärr är dessa mediciner förknippade med oönskade och ibland svåra biverkningar och sökandet efter nya möjliga läkemedel pågår ständigt.Vi har i denna avhandling prövat två möjliga vägar att hämma immunförsvaret i&lt;br/&gt;&lt;br&gt; sammanlagt fem olika publikationer. Studierna har gjorts i laboratorium och som djurförsök.&lt;br/&gt;&lt;br&gt; I det första arbetet testades kombinationer av antikroppar som riktar sig mot några av de signaler som medverkar till T-cellernas aktivering. De testade antikropparna hämmar de signaler som behövs för att sätta igång en&lt;br/&gt;&lt;br&gt; avstötningsreaktion där T-cellerna spelar en avgörande roll. Dessa celler är en del av kroppens immunförsvar och medverkar till avstötning av främmande organ.&lt;br/&gt;&lt;br&gt; Tre olika antikroppar, var och en för sig eller i kombination, gavs som behandling i en ö-cellstransplantationsmodell på mus. Detta är en transplantation av insulinproducerande celler från bukspottskörteln. Målet med en sådan transplantation är att bota diabetes. Behandlingen med kombination av två eller tre antikroppar var mer effektiv än att behandla med bara en substans. I kombinationsgrupperna noterades ingen avstötningsepisod under en uppföljningstid på 100 dagar.&lt;br/&gt;&lt;br&gt; I de nästkommande fyra arbetena utvärderade vi en ny sorts molekyl som kallas MCT1-hämmare. Vi utvecklade sju olika strukturella varianter av molekylen för att hitta en så optimal substans som möjligt för att minska avstötning och biverkningar.&lt;br/&gt;&lt;br&gt; Denna molekyl blockerar en receptor på cellytan. Genom denna blockad, hämmar denna molekyl ökningen av T-celler som sker vid aktivering av immunförsvaret.&lt;br/&gt;&lt;br&gt; Olika transplantations-modeller utfördes med varierande grad av komplexitet på råttor och möss för att hitta gränserna för vad denna molekyl kunde åstadkomma i olika kombinationer och doser.&lt;br/&gt;&lt;br&gt; Substansen var effektiv för att förhindra avstötning av både hjärta och hudtransplantat på råttor. Molekylen visade sig vara mer effektiv när den gavs med injektioner under huden än när den gavs i lösning som kunde sväljas ned. MCT1-hämmare prövades också i en ö-cellsmodell på möss, men den hade tyvärr begränsad effekt på ö-cellernas överlevnad.&lt;br/&gt;&lt;br&gt; I det sista arbetet transplanterades råttor med hjärta från en annan råtta till mottagarens halskärl utan att ge immunhämmande behandling. Sedan lät man transplantatet avsiktligt stötas av. Detta för att skapa en modell där råttorna skulle utveckla ett överkänsligt immunförsvar. Dessa råttor transplanterades med ytterligare ett hjärta till ljumsken och fick först då behandling med den immunhämmande molekylen. Detta visade sig vara gränsen för vad denna molekyls immunhämmande kapacitet. Alla transplanterade hjärtan stöttes av inom kort tid. Liknande resultat kunde ses när vi utförde transplantation från annan art till råtta, &lt;br/&gt;&lt;br&gt; sk xenotransplantation.Sammanfattningsvis är detta arbete en del av den forskning som pågår i världen för att&lt;br/&gt;&lt;br&gt; hitta nya läkemedel som förhindrar avstötning vid transplantation. Studierna visar i viss omfattning lovande resultat och vidare fördjupning och forskning kan göra det möjligt för dessa substanser att användas på transplanterade patienter. En av antikropparna i det första arbetet har prövats på människa och används nu i kombination med andra immunhämmande läkemedel vid transplantation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/84c709b6-780e-4159-b551-9a76d7d4e491</url> </location> </relatedItem> <originInfo> <publisher>Surgery</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Surgery</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-34-2</identifier> <identifier type="oldLupId">4285708</identifier> <part> <detail type="volume"> <number>2014:11</number> </detail> <extent unit="pages"> <total>128</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-01-31T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>84c709b6-780e-4159-b551-9a76d7d4e491</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:31+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:31+02:00</recordDateApproved> </recordInfo> </mods>

In the clinical situation, the graft material used for cell therapy must, most likely, be of human origin. The human fetal brain is one potential source of neural stem cells (NSCs) for cell replacement therapy in neurodegenerative disorders such as stroke. Stroke is the leading cause of disability in adult humans and treatments for beneficial and efficient recovery are today lacking. In the most common form of human stroke, i.e. occlusion of the middle cerebral artery, mainly neurons in the cortex and striatum die. Therefore, we wanted to generate NSCs lines derived from the human fetal cortex and striatum and explore whether they maintain an intrinsic cellular identity in culture, consistent with their region of origin. Moreover, we wanted to investigate their capacity and potential after transplantation into the striatum of intact newborn and stroke-lesioned adult rats. Furthermore, we wanted to determine whether we could drive the NSCs towards neuronal fate by overexpressing the transcription factor Pax6. We found that the cortical and striatal NSCs have similar properties during expansion as neuropsheres. However, upon long-term differentiation in vitro, the cortical and striatal NSCs generated region-specific neuronal subtypes. After transplantation into the neonatal rat striatum, both cortical and striatal NSCs survived well and migrated similar distances, and had the capacity to differentiate into astrocytes, oligodendrocytes and mature neurons. When the NSCs were grafted into the striatum of rats subjected to stroke, both cortical and striatal NSCs survived and migrated to the same extent, and almost exclusively generated neurons outside the graft core. However, the striatal NSCs occupied a larger volume of the striatum and generated a higher proportion of neurons with molecular identity of striatal neurons. Upon overexpression of Pax6, the in vitro generation of neurons increased from the striatal NSCs and with maintained region-specificity. When striatal NSCs overexpressing Pax6 was implanted into the neonatal rat, there was an increased generation of neuroblasts compared to control. Taken together, it is possible to consider cortical and striatal NSCs derived from the human fetus as a safe cell source with a very strong neurogenic capacity as promising candidates for cell replacement therapy. However, before any clinical application of cell replacement therapy can be considered, there are several key points to address; the selection of established and guaranteed safe cell sources with fully controllable differentiation potential, the complete knowledge of disease mechanisms and progression, the optimized number of cells and time for transplantation, and the careful selection of patients with best prognosis to benefit from cell therapy.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Stroke är en sjukdom som främst drabbar äldre och är den största anledningen till att människor får olika slags handikapp såsom förlamning och afasi. Det finns ännu ingen effektiv behandling för att lindra symtom och lidande efter en stroke, förutom rehabilitering, och därför kostar stroke samhället enormt mycket pengar. Befolkningen blir allt äldre, vilket även medför att antalet människor som får stroke ökar, därför är det oerhört viktigt, både ur patientens och samhällets synvinkel, att utveckla nya och effektiva behandlingsmetoder. En typ av behandling skulle kunna vara att transplantera nya celler till strokepatienten, för att antingen ersätta de celler som dött på grund av stroken eller påverka de celler som finns i hjärnan. Stamceller från hjärnan är omogna celler som kan föröka sig själva genom delning och ge upphov till olika mogna celltyper i hjärnan. Stamceller går att odla utanför hjärnan i så kallade cellkulturer, eftersom de genom delning kan bli till fler stamceller. När stamcellerna sedan mognar kan de generera nya nervceller. Redan för flera år sedan har själva principen av cell transplantation bevisats fungera i kliniska försök. Celler tagna direkt från aborterade foster transplanterades in i hjärnan på patienter med Parkinsons sjukdom, vilket avsevärt förbättrade patienternas tillstånd. Vi måste nu utveckla säkra och väl karaktäriserade stamcellslinjer som kan fungera som en obegränsad cellreservoar för transplantationer, då användningen av primär fostervävnad är problematisk rent etiskt samt att mängden tillgänglig vävnad är mycket begränsad. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Vid en stroke dör främst nervceller i två regioner av hjärnan, kortex och striatum. Därför genererade vi kortikala och striatala stamcellslinjer, där vävnad initialt togs från aborterade foster. Vi ville undersöka skillnaden mellan kortikala och striatala stamceller som odlats och expanderats under lång tid i cellkulturer. Ett mål var att ta reda på om stamcellerna fortfarande kunde ge upphov till de nervceller som är typiska för respektive region av hjärnan som de ursprungligen kom ifrån. Vi kom fram till att så är fallet – de kortikala och striatala stamcellerna blev kortex- respektive striatumspecifika nervceller. Nästa mål var att transplantera stamcellerna till råtthjärnor, både intakta och strokeskadade, för att utröna vilken påverkan miljön i hjärnan hade på cellerna samt deras kapacitet att överleva, mogna ut och i så fall till vilka typer av celler. Vi fann att både de kortikala och de striatala stamcellerna överlevde, integrerade med värdhjärnan och utvecklades till mogna nervceller. Det tredje målet var att försöka styra stamcellerna till att producera fler nervceller, då antalet nervceller brukar vara tämligen lågt i förhållande till andra typer av celler. Vi modifierade cellerna genetiskt genom att föra in en gen, Pax6, som tidigare, från studier på stamceller från möss, har visats öka antalet nybildade nervceller. Vi kunde visa att Pax6 ökade antalet nervceller som de striatala stamcellerna genererade och att de nya nervcellerna fortfarande var striatumspecifika. Dessutom transplanterade vi de Pax6-överuttryckande stamcellerna till intakt råtthjärna och såg att de även i hjärnan kunde ge upphov till fler neuronala celler jämfört med celler utan överuttryckt Pax6. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; De resultat som redovisas in den här avhandlingen gör att vi kan säga att kortikala och striatala neurala stamceller från mänskliga foster är en möjlig reservoar av celler för transplantation. Vidare innehar de en hög kapacitet att kunna generera nervceller, både i odling och efter transplantation till råtthjärna. Innan vi kan använda den här typen av behandling på patienter återstår dock mycket forskning kring cellernas förmåga att funktionellt integrera med redan existerande nervceller i hjärnan, att förstå de sjukdomsmekanismer som äger rum vid stroke, att bestämma vilka patienter som är bäst lämpade för cellterapi och att ta reda på hur många celler som ska placeras var i hjärnan samt när, det vill säga vid vilken tidpunkt efter stroke.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/6bbc0482-0724-4948-a450-783eb2c5fe5b</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="therese_kappa.pdf">https://portal.research.lu.se/files/3438763/1169757.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">6685327</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Pax6</topic> <topic>fetal cortex and striatum</topic> <topic>human</topic> <topic>neural stem cells</topic> <topic>transplantation</topic> <topic>neurospheres</topic> <topic>stroke</topic> <topic>overexpression</topic> <topic>region-specific properties</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-23-1</identifier> <identifier type="oldLupId">1150540</identifier> <part> <detail type="volume"> <number>2008:70</number> </detail> <extent unit="pages"> <total>156</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-06-12T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>6bbc0482-0724-4948-a450-783eb2c5fe5b</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:33+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:04:02Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:33+02:00</recordDateApproved> </recordInfo> </mods>

A group of 303 gynaecologically asymptomatic women, aged 20–39 years with normal menstrual cycles (NMC) and another group of 213 women aged 20–39 years using combined oral contraceptives (COC) were examined using two-dimensional (2D) and 3D transvaginal ultrasound once between cycle day 4 and 8. Ovarian volume and the number of antral follicles were found to decrease with age, while no unequivocal changes in vascular indices were seen in women with NMC. In women using COC the number of antral follicles also decreased with age. The ovarian volume and the number of follicles were determined for different age groups, and these results can be used as reference data. A group of women with ovarian tumours (n=106) was examined using 2D and 3D transvaginal ultrasound. Tumour vascularization was assessed using 3D power Doppler ultrasound in the whole tumour and in a 5-cm3 spherical sample in the most vascularized part of the tumour. A logistic regression model with only grey-scale ultrasound variables (size of the largest solid component, wall irregularity, mean diameter of the lesion) was created to predict malignancy. The flow index in the 5-cm3 sample and the branching of vessels in the whole tumour provided additional information to the grey-scale model, but the diagnostic performance was only slightly improved.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Äggstockarna genomgår förändringar under en normal menstruationscykel. I samband med tumörväxt i äggstockarna utvecklas nya blodkärl. Dessa förändringar kan upptäckas med både tvådimensionellt (2D) och tredimensionellt (3D) gråskale- och Doppler-ultraljud. Med Doppler-ultraljud kan man upptäcka blodkärl och uppskatta blodflödeshastigheterna i blodkärlen. Referensvärden för resultat av 3D gråskale- och power-Doppler ultraljudsundersökning av äggstockarna hos gynekologiskt friska kvinnor i olika åldrar saknas. En metod där referensvärden saknas är inte kliniskt användbar. 2D färg-Doppler ultraljud förbättrar inte förmågan att skilja mellan godartade och elakartade äggstockstumörer jämfört med att använda bara gråskale-ultraljud. Med hjälp av power Doppler ultraljud kan man troligen upptäcka mindre blodkärl än med färg-Doppler ultraljud.&lt;br/&gt;&lt;br&gt; Tredimensionellt (3D) ultraljud är ett icke-invasiv teknik som har använts inom både obstetrik och gynekologi sedan 1990-talet. 3D ultraljud erbjuder möjlighet att räkna ut volymen av ett organ och att uppskatta genomblödningen i hela volymen av ett organ eller tumör. Med 2D ultraljud kan man uppskatta genomblödningen bara i en ”skiva” genom ett organ eller en tumör. Volymen av oregelbundna strukturen kan räknas ut på ett mer exakt sätt med 3D än 2D ultraljud. Med hjälp av 3D programvara kan man bearbeta ultraljudsbilderna och framställa 3D bilder av blodkärlsträdet i ett organ eller i en tumör.&lt;br/&gt;&lt;br&gt; Syftet med de arbeten som ingår i avhandlingen var att fastställa normalvärden för resultat av 3D-ultraljudsundersökning av äggstockar hos gynekologiskt friska kvinnor i fertil ålder med och utan p-piller och att undersöka om antal folliklar och äggstocksvolym samt genomblödningen i äggstockarna förändras med åldern; samt att utvärdera om 3D ultraljud kan skilja mellan god-artade och elakartade äggstockstumörer och om 3D ultraljudsundersökning av äggstockstumörers blodcirkulation ger information i tillägg till gråskale-ultraljud.&lt;br/&gt;&lt;br&gt; Från befolkningsregistret inbjöds 20–39 år gamla kvinnor till undersökning av äggstockarna med 2D och 3D ultraljud. Ultraljudsundersökningen gjordes en gång på cykeldag 4–8. Kvinnor med äggstockstumör undersöktes med 2D och 3D ultraljud en gång inom 3 månader innan operation. 3D ultraljudsvolymerna analyserades med hjälp av dataprogrammet 4D View™ (GE, Healthcare, Zipf, Österrike) med VOCAL™ eller SonoAVC™ mjukvara. SonoAVC användes för beräkningar av antalet folliklar (äggblåsor) i äggstockarna. Volymen och genomblödningen av äggstockarna och äggstockstumörerna beräknades med hjälp av VOCAL mjukvara. Tre power Doppler-ultraljudsindex (avspeglande blodcirkulationen i den definierade volymen) räknades ut: vaskulariserings index (VI), flödes index (FI) och vaskulariserings-flödes index (VFI). VI anses avspegla tätheten av blodkärl i den undersökta volymen, FI anses avspegla antalet blodkroppar i blodkärlen som undersöks, och VFI anses avspegla både tätheten av blodkärl och antalet blodkroppar. Power Doppler-ultraljudsindex räknades ut i hela tumörvolymen men även i en 5cm3 sfärisk ”ultraljudsbiopsi” som valdes i den mest vaskulariserade tumördelen på basen av subjektiv bedömning. Kärlträdet i hela tumören och i ”biopsin” framställdes också som en roterande 3D-bild. Följande kärlmorfologitecken analyserades i dessa roterande bilder av två oberoende undersökare: kärlförgreningar, kärltäthet, kaliberväxlingar, ”färgsjöar”, kärlvindlingar och ”bryggor” mellan blodkärl. &lt;br/&gt;&lt;br&gt; Resultaten avseende gynekologiskt friska kvinnor analyserades separat för kvinnor med normal menscykel och för kvinnor med kombinerade p-piller och jämfördes sedan. Sammanlagt 303 kvinnor med normal menscykel och 213 kvinnor med kombinerade p-piller inkluderades. Höger äggstock var större, hade fler folliklar och större follikelvolym än vänster äggstock i båda grupperna. Power Doppler-ultraljudsindex var högre i höger äggstock än i vänster hos kvinnor med normal menscykel men inte hos kvinnor med kombinerade p-piller. Äggstocksvolym, antal folliklar och total follikelvolym minskade signifikant med åldern hos kvinnor med normal menscykel medan inga förändringar sågs i genomblödningen. Hos kvinnor med kombinerade p-piller minskade antalet folliklar signifikant med åldern. Mer än hälften av kvinnorna med normal menstruationscykel hade ”polycystiska äggstockar” enligt gällande ultraljudskriterier. Så mycket som 11% av kvinnorna med kombinerade p-piller hade folliklar större än 10 mm. Kvinnor med normal menscykel hade större äggstockar med större antal folliklar och högre power Doppler-ultraljudsindex än kvinnor med kombinerade p-piller.&lt;br/&gt;&lt;br&gt; Analys av 3D power Doppler-ultraljudsindex gjordes i 106 äggstockstumör och kärlträdets morfologi analyserades i 104 tumör. Av dessa tumörer var 27 elakartade. Elakartade tumörer var bättre genomblödda och var större än godartade tumörer och alla kärlträdstecken skiljde sig mellan godartade och elakartade äggstockstumörer. Ju större tumören var och ju större solida komponenter tumören innehöll (bedömt med gråskale-ultraljud) desto större var risken för elakartad tumör. Oregelbundenheter i tumören vid gråskale-ultraljudsundersökning ökade också risken för elakartad tumör. Dessa gråskalevariabler predikerade rätt alla elakartade tumörer och misstolkade 8 godartade tumörer som elakartade. Flödesindex förbättrade förmågan att skilja mellan godartade och elakartade tumörer: ytterligare två godartade tumörer klassades rätt när flödesindex adderades till informationen från gråskalevariablerna. När förgrening av blodkärl i hela tumören adderades till informationen från gråskalevariablerna klassades ytterligare 4 tumörer rätt och denna modell hade den bästa förmågan att skilja mellan godartade och elakartade tumörer.&lt;br/&gt;&lt;br&gt; Sammanfattningsvis, äggstocksvolym och antal folliklar minskar med kvinnans ålder men inga mätbara förändringar tycks ske i äggstockarnas genomblödning. Gråskale-ultraljudsresultaten kan användas som referensdata för 3D ultraljudsundersökning av äggstockarna på cykeldag 4–8 hos kvinnor mellan 20 och 39 år. &lt;br/&gt;&lt;br&gt; Kärlträdets morfologi bedömt med 3D power Doppler-ultraljud kan skilja mellan godartade och elakartade äggstockstumörer men adderar bara litet till gråskale-information. Det vore av värde att utvärdera 3D ultraljud som metod för att skilja mellan godartade och elakartade tumörer som är svårklassificerade om man bara använder gråskale-ultraljud. Svårklassade tumörer utgör 7–10% av alla äggstocktumörer.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c3ca26c5-e6e4-4560-8108-2acb0fc093fa</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Ligita.Jokubkiene.avhandling.pdf">https://portal.research.lu.se/files/3439167/2369510.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">25807791</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Department of Clinical Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>ovary</topic> <topic>ovarian follicle</topic> <topic>ovarian neoplasms</topic> <topic>ultrasonography</topic> <topic>three-dimensional imaging</topic> <topic>Doppler ultrasound imaging</topic> <topic>vascular morphology</topic> </subject> <subject authority="lup"> <topic>Gynaecology, Obstetrics and Reproductive Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-87-1</identifier> <identifier type="oldLupId">2369505</identifier> <part> <detail type="volume"> <number>2012:25</number> </detail> <extent unit="pages"> <total>182</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-03-30T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>c3ca26c5-e6e4-4560-8108-2acb0fc093fa</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:39+02:00</recordDateApproved> </recordInfo> </mods>

The evidence for this cosmic event includes abundant centimeter to decimeter-sized fossil meteorites and elevated levels of sediment-dispersed extraterrestrial L-type chromite found in a stratigraphical interval corresponding to the uppermost Lenodus antivariabilis, the L. variabilis, and the Yangtzeplacognathus crassus conodont biozones, and the lower Microzarkodina hagetiana Subzone of the Lenodus (Eoplacognathus?) pseudoplanus Zone. Whereas these fossil meteorites are found only on freshly-sawed limestone-slabs at the active Thorsberg quarry on Mount Kinnekulle, southern Sweden, the occurrence of chromite has been recorded from various localities in Sweden, as well as in Russia and south-central China. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; A high-resolution conodont biostratigraphy over the c. 2.5 m thick, chromite-rich interval at the abandoned Hällekis quarry, Kinnekulle, was established in order to improve correlation between chromite-yielding sequences. Since the meteorite/chromite-rich interval here directly associates with a conspicuous rock sequence known as the ‘Täljsten’ interval, these strata were also investigated for palaeoecological and environmental changes. This anomalous interval has previously been suggested to represent a relative sea-level fall, but it has also been speculated that its formation could have been linked to the L-chondrite parent body break-up. Hence, the nature of the ‘Täljsten’ needed to be further explored in terms of faunal dynamics and depositional setting. The conodont fauna demonstrated continuous faunal reorganizations throughout the sampled sequence, as did additional microfaunal components. Along with observed changes in microfacies, it could be verified that the chromite-rich interval coincides with a gradually progressing regression-transgression cycle. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; An interesting find of tiny Panderodus conodont elements, including a serrate arcuatiform element, was made in a bed deposited just prior to the inferred maximum lowstand of the ‘Täljsten’ interval. Such serrate elements have previously been referred to as ecophenotypes of non-serrate forms, but sometimes also as distinctive species or subspecies. The Hällekis specimens, described as Panderodus serratus hallekisensis, represent one of the earliest records of the genus and hence provided clues to the primitive morphology and suprageneric relationship of Panderodus. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Due to an observed tendency for overlapping morphologies and inconsistencies in identifications, the shapes of dextral Pa-elements from the zonal indices L. variabilis, Y. crassus and L. (E?) pseudoplanus were quantitatively compared using landmark-based geometric morphometrics.&lt;br/&gt;&lt;br&gt; Linear shape of the posterior and posterio-lateral denticle rows combined was considered to best reflect the overall shape of the element-type in question, and 23 landmarks were used for the analysis; 4 fixed and 19 sliders (semi-landmarks). The analyses highlighted large-scale shape and symmetry related differences between the three species, but also revealed some overlaps. It also became clear that the three taxa display notable shape-variation of the dextral Pa element, a matter only looked into closer for L. variabilis. The Y. crassus elements included in the analysis suggest that the Baltoscandian and Chinese forms cannot be regarded as equivalents. The contingencies regarding the zonal indices naturally influence, e.g., the potential for a high-resolution correlation of chromite distribution between Kinnekulle and coeval sedimentary sequences at other localities. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; It was recently shown that the &amp;gt;1000km2 Osmussaar Breccia in north-western Estonia contains non-reworked L-type chromite, suggesting a connection to an L-chondritic impactor. An assessment of the conodont fauna of the limestones above the brecciate layers indicates that the formation of the breccia concurred with the deposition of the meteorite/chromite-yielding strata in Sweden. The limestone bed immediately superposing the breccia could be brought to the Microzakodina ozarkodella Subzone of the L. (E?) pseudoplanus Zone, i.e. only slightly higher stratigraphically than the recognized upper limit for high abundances of extraterrestrial material. This stratigraphical divergence as compared to the Swedish interval can be explained by a period of non-deposition and a resulting hiatus, a conceivable scenario considering the numerous sedimentation-gaps characterizing the early Darriwilian of north-western Estonia.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Conodonter är en numera utdöd grupp havslevande djur vars systematiska ställning länge varit föremål för debatt. De var i det längsta kända enbart genom sina millimeterstora, kalciumfosfatiska element, vilka vi idag vet satt i djurens munhåla. Sådana conodontelement beskrevs för första gången 1856 av Christian Heinrich Pander, men det skulle dröja närmare 130 år innan de kunde knytas till ett helkroppsfossil. 1983 hittades ett första avtryck av djuret, vilket liknade en liten ål med fenor på bakkroppen, dock utan förbenad ryggrad eller andra hårddelar utöver elementen. Numera anser de flesta att conodonterna tillhör ryggsträngsdjuren, det vill säga samma djurstam som vi själva, och därtill har uppfattningen att de bör föras till ryggradsdjuren fått starkt fotfäste. Hittills har 11 avtryck av conodonter påträffats vilket gör dem till riktiga rariteter. Däremot kan conodontelement vara väldigt vanliga i marina sedimentära bergarter och tusentals exemplar per kilo kan ibland utvinnas genom att lösa upp kalksten i svag syra. &lt;br/&gt;&lt;br&gt; Conodonternas systematik baseras helt och hållet på elementen, eller snarare på det rekonstruerade arrangemanget av dessa till olika sorters födoinsamlingsapparater. Den huvudsakliga funktionen för conodontapparaterna är fortfarande osäker. En hypotes är att elementen fäste i broskplattor och att apparatens främre del kunde öppnas och slutas muskulärt, vilket skulle tillåta djuren att greppa sin föda. Andra menar att apparaten var beklädd med cilier och att födointaget skedde genom filtrering. &lt;br/&gt;&lt;br&gt; Conodonterna existerade i ungefär 300 miljoner år, från mellersta kambrium till slutet av trias, och förekom i många olika marina miljöer. Gruppen utvecklades snabbt och många arter hade vid geografisk spridning vilket gör fossilen värdefulla för åldersbestämning och korrelation mellan marina avlagringar på olika platser. Denna avhandling behandlar conodonter som levde under ordovicium (489 – 443 miljoner år sedan) och innefattar bland annat just sådana relativa åldersbestämningar och korrelationer. &lt;br/&gt;&lt;br&gt; Den ordoviciska perioden kännetecknas bland annat av ett varmt klimat med koldioxidhalter som var högre än dagens nivåer, en höggradig kontinentaldrift, höga havsnivåer och omfattande vulkanism. Under den här tiden skedde dessutom en av de viktigaste evolutionära händelserna i livets historia genom en avsevärd ökning i marin biodiversitet på familj-, släkt-, och artnivå. Ökningen skedde (geologiskt sett) snabbt – under loppet av ungefär 25 miljoner år – och har kommit att kallas ”den stora ordoviciska radiationen”. &lt;br/&gt;&lt;br&gt; Studierna i avhandlingen berör mellersta ordovicium, en tid då Jorden drabbades av ett ovanligt stort inflöde av kosmiskt material. Detta var följden av att en större himlakropp splittrades efter en kollision ute i asteroidbältet för ungefär 470 miljoner år sedan. Mycket av kunskapen om denna händelse kommer från undersökningar av kalkstenslagerföljden på Kinnekulle i Västergötland, där man inom ett 1-2 miljoner år långt intervall i undre mellanordovicium (motsvarande omkring 2.5 meter kalksten) funnit ett stort antal fossila meteoriter samt höga halter av det accessoriska mineralet kromit. &lt;br/&gt;&lt;br&gt; Avhandlingens första studie syftade till att förbättra möjligheterna för korrelation mellan ovan nämnda intervall och likåldriga lager utanför Kinnekulle. Detta innebar upprättandet av en detaljerad biostratigrafi, det vill säga en sammanställning av successivt förekommande conodont-arter genom intervallet. Eftersom den höga förekomsten av kosmiskt material sammanfaller med en säregen, omkring 1.5 meter tjock kalkstenssekvens, undersöktes conodontfaunan även med hänsyn till miljömässiga förändringar. Den anomala sekvensen, i folkmun känd som &quot;Täljstenen&quot;, är iögonfallande på grund av sin grå färg i den annars rödfärgade orthoceratitkalkstenen och tillsammans med något avvikande litologi och fossilinnehåll signalerar det i sin tur någon form av skillnad i avsättningsmiljö gentemot ovan- och underliggande lager. Det har tidigare föreslagits att dessa lager avsattes under en tid då havsnivån tillfälligt var relativt låg, men eftersom avsättning skedde strax efter kollisionen i asteroidbältet har det också spekulerats kring direkta och indirekta kopplingar mellan &quot;Täljstenen&quot; och astronomiska händelser. &lt;br/&gt;&lt;br&gt; För att få reda på mer om de förhållanden som rådde undersöktes även andra förekommande mikroskopiska fossilgruppers faunadynamik, samt småskaliga sedimentvariationer. Genom tolkningar av bland annat de fossila faunornas skiftande karaktär kunde det bekräftas att tiden för det höga inflödet av meteoriter sammanföll med en tydlig och gradvis framåtskridande havsnivåsänkning. Tolkningar av conodontfaunan visade dessutom att havsnivåsänkningen inleddes innan avsättningen av &quot;Täljstenens&quot; karaktäristiskt grå kalkstenssediment. &lt;br/&gt;&lt;br&gt; Detaljerade undersökningar kan medföra oväntade fynd. Ungefär mitt i &quot;Täljstenen&quot; hittades ett fåtal mycket små conodontelement karaktäristiska för släktet Panderodus. Fynden var speciella eftersom de representerar en av de absolut äldsta förekomsterna av släktet. De små &quot;tänderna&quot; på ett av elementen tydde på att de tillhörde Panderodus serratus, ett artnamn vars innebörd emellertid har varierat genom åren. Sådana element har dessutom tidigare varit kända under andra namn. Fyndet motiverade därför en separat studie där elementen beskrevs och deras vidare betydelse och systematik diskuterades. &lt;br/&gt;&lt;br&gt; En grupp conodonter som har visat sig särskilt användbara för regionala såväl som mer långväga korrelationer är de som bar plattformsliknande element i sin apparat. Just plattformselementen hade en förhållandevis snabb evolutionstakt, vilket gör att man enklare kan urskilja tidstypiska former. Dessa brukar i sin tur vanligen benämnas som olika arter. De arter som huvudsakligen används för att definiera olika tidsavsnitt inom det meteorit- och kromitrika intervallet är Lenodus variabilis, Yangtzeplacognathus crassus och Lenodus (Eoplacognathus?) pseudoplanus (vilka även uppträder i denna ordningsföljd). Dessa har bland annat använts för att sammankoppla kromitrika nivåer i den kinesiska Puxi-sektionen med det aktuella intervallet på Kinnekulle.&lt;br/&gt;&lt;br&gt; Under arbetet med conodontfaunan på Kinnekulle visade det sig att plattformselement som enligt rådande standard skulle tillhöra L. variabilis var väldigt formmässigt varierande. Det kan tyckas naturligt med tanke på artnamnet, men problemet var att vissa element tycktes uppvisa karaktärsdrag utmärkande även för de två senare och tidstypiska arterna Y. crassus och L. (E?) pseudoplanus. Själva formen hos dessa element är central för identifikationen av respektive art och en studie inleddes där elementens form karaktäriserades digitalt med hjälp av så kallad landmärkesbaserad morfometri, för att sedan analyseras statistiskt med avseende på typ och grad av formvariation. Av totalt två varianter plattformselement (Pa och Pb) inkluderades bara högerelementen av Pa-typ i studien. Metoden fungerade bra för att visualisera den stora formvariationen hos L. variabilis och användes också för jämförelser mellan denna och de andra två arterna. Analysen belyste grundläggande formskillnader mellan arterna men avslöjade också vissa överlappningar, vilka i sin tur gav ledtrådar kring utvecklingen från L. variabilis till de senare formerna Y. crassus och L. (E?) pseudoplanus. Studien visade även att de svenska Y. crassus-elementen hade formmässigt mer gemensamt med L. variabilis än med sina kinesiska motsvarigheter. &lt;br/&gt;&lt;br&gt; Avhandlingens sista studie baserades på en märklig lagerföljd på den lilla ön Osmussaar utanför Estlands nordkust. Här är vissa mellanordoviciska kalkstenslager tydligt uppbrutna (så kallat breccierade) och genomträngda av sandstensådror, vilket har tolkats som resultatet av en jordbävning eller ett asteroidnedslag. Ingen närliggande likåldrig krater har identifieras, vilket talar emot nedslagsteorin. Nyligen påvisades emellertid kromitkorn i breccian, vilka är av den typ som härrör från kollisionen i asteroidbältet för 470 miljoner år sedan. Upptäckten tyder alltså på att breccian trots allt är relaterad till ett asteroidnedslag och att asteroiden härstammade från den splittrade himlakroppen. Frågan var om nedslaget tidsmässigt stämde överens med det höga inflödet av kosmiskt material som registrerats i undre mellanordovicium? Conodonterna i kalkstenen som direkt överlagrar breccian (och därmed representerar den första sedimentationen efter dess bildning) visade att en justering av tidigare åldersuppskattning är befogad. Resultaten stödjer i sin tur teorin om att själva bildningstillfället för breccian var samtidig med avsättningen av de meteorit- och kromitrika lagren på Kinnekulle.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/abf9dac9-15a5-4037-9f8b-86e56b2a5202</url> </location> </relatedItem> <originInfo> <publisher>Department of Earth and Ecosystem Sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Conodonts</topic> <topic>biostratigraphy</topic> <topic>taxonomy</topic> <topic>palaeoecology</topic> <topic>morphometrics</topic> <topic>extraterrestrial chromite</topic> <topic>meteorites</topic> <topic>Darriwilian</topic> <topic>Middle Ordovician</topic> <topic>Baltoscandia</topic> </subject> <subject authority="lup"> <topic>Geology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Litholund theses</title> </titleInfo> <identifier type="issn">1651-6648</identifier> <identifier type="issn">1651-6648</identifier> <identifier type="isbn">978-91-86746-73-5</identifier> <identifier type="oldLupId">2205114</identifier> <part> <detail type="issue"> <number>21</number> </detail> <extent unit="pages"> <total>118</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-12-14T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>abf9dac9-15a5-4037-9f8b-86e56b2a5202</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:41+02:00</recordDateApproved> </recordInfo> </mods>

However, anatomical limitations such as short or absent proximal sealing neck and poor access vessels exclude up to 50% of patients. In attempt to increase the number of patients suitable for EVAR, fenestrated devices have emerged. In this new era, precise and reproducible imaging is of paramount importance for device planning and assessing operative risk and success. Thin-slice CT scans, digital imaging and software to analyze and reconstruct vessels in 3D have rendered previous imaging methods out-of-date.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The aim of this thesis was to evaluate: &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; 1. The results of endovascular treatment of juxtarenal aortic aneurysms with fenestrated devices (FEVAR). &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; 2. Different methods and measuring modalities used in preoperative aneurysm diameter measurements.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; 3. Subjective and objective methods used for iliac tortuosity assessment and to establish a simple reproducible method for iliac tortuosity evaluation prior to endovascular repair.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; 4. The correlation of the anatomic severity grading score to operative success and outcomes after FEVAR.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Our results show that FEVAR is a procedure with good short- and midterm results that offers a valid treatment alternative to patients unsuitable for standard EVAR. Ultrasound readings are consistently smaller then when measured by any means on CT reconstructions, which should be taken into account when recommending intervention for smaller aneurysms. Subjective assessment of iliac tortuosity has poor agreement with iliac tortuosity index, which is reproducible with good agreement between observers. Our new more simple method for iliac tortuosity evaluation can replace tortuosity index. The anatomic severity grading score is of value in predicting procedure time, adverse events, adjunctive maneuvers, radiation exposure and postoperative complications after FEVAR.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1599f4d7-6602-446c-81e5-70d1193efd97</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thorarinn_Kristmundsson_avhandling.pdf">https://portal.research.lu.se/files/3439270/2520355.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9411124</note> <accessCondition type="restrictionOnAccess">LU/LTH access</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Abdominal aortic aneurysm</topic> <topic>juxtarenal aneurysm</topic> <topic>endovascular repair</topic> <topic>fenestrated endovascular repair</topic> <topic>imaging</topic> <topic>computed tomography</topic> <topic>ultrasound.</topic> </subject> <subject authority="lup"> <topic>Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-01-2</identifier> <identifier type="oldLupId">2520351</identifier> <part> <detail type="volume"> <number>2012:39</number> </detail> <extent unit="pages"> <total>118</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-05-21T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>1599f4d7-6602-446c-81e5-70d1193efd97</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:41+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-21T11:04:02Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:41+02:00</recordDateApproved> </recordInfo> </mods>

The question of quality of life of the survivors is, therefore, important. The TGCC treatment, and thereby its side-effects may vary. A contributing factor to this variation is also genetically determined inter-subject difference in the sensitivity to the adverse effects of cancer therapy. The aim of this thesis has been, in order to improve the management and counselling of TGCC patients, to increase the level of knowledge regarding impairment of reproductive functions as well as the risks of emotional disorders (EMD) related to TGCC and its treatment.&lt;br/&gt;&lt;br&gt; In article I, impact of therapy and androgen receptor (AR) polymorphisms on sperm concentration was investigated. Radiotherapy (RT) or 3 to 4 cycles of chemotherapy (SCT) caused initial decline in sperm concentration, which returned to pre-treatment levels 2 to 5 years after therapy. In the SCT group, sperm concentration 1 to 2 years post-treatment was inversely correlated to the androgen receptor (AR) CAG repeat length, indicating a genetic variation in the recovery of sperm concentration. In article II, risk factors for developing hypogonadism were studied. SCT and RT treated were at higher risk of hypogonadism, 6 and 12 months post-treatment as compared to those who received 1 to 2 cycles of chemotherapy. Microlithiasis and hormone deficiency prior to treatment predicted increased risk of hypogonadism after cancer therapy. In article III, TGCC patients, 3 to 5 years after treatment, were compared to the general population concerning prevalence of sexual dysfunctions. A higher proportion of TGCC patients had low sexual desire and erectile dysfunction. Neither hypogonadism nor treatment modality had any obvious impact on the risk of these sexual problems. In article IV, the presence of EMD was investigated, 3 to 5 years after TGCC therapy and related to hypogonadism, AR polymorphisms and treatment modality. Neither anxiety nor depression was overrepresented in hypogonadal TGCC patients and no association between AR polymorphisms and EMD was found. Patients treated with than four cycles of cisplatinum based chemotherapy due to refractory or relapsed disease were more prone to experiencing symptoms of anxiety.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/95a60f3b-10d4-4a48-95f0-8f8210686b81</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Eberhard.pdf">https://portal.research.lu.se/files/3439337/1363565.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1156987</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Jakob Eberhard, Dep of Clinical Sciences, Malmö University Hospital, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>depression</topic> <topic>sexual dysfunction</topic> <topic>hypogonadism</topic> <topic>testicular cancer</topic> <topic>fertility</topic> <topic>anxiety</topic> <topic>androgen receptor</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> <topic>Gynaecology, Obstetrics and Reproductive Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-18-9</identifier> <identifier type="oldLupId">1363171</identifier> <part> <detail type="volume"> <number>2009:31</number> </detail> <extent unit="pages"> <total>168</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-04-17T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>95a60f3b-10d4-4a48-95f0-8f8210686b81</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:43+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:43+02:00</recordDateApproved> </recordInfo> </mods>

The driving force and benefactors of such devices are (but not limited to) e-health&lt;br/&gt;&lt;br&gt; system, sensor network applications, security systems, environmental applications, and home automation systems. These markets&lt;br/&gt;&lt;br&gt; have launched a massive trend towards ultra low-energy and ultra low-voltage devices. As the technology scales, the dimensions&lt;br/&gt;&lt;br&gt; of a transistors have become extremely small, leading to reliability and process variation issues. Above all, with the ability of&lt;br/&gt;&lt;br&gt; placing millions of gates in a small area, high current consumption have become one of the key factors in modern high-performance&lt;br/&gt;&lt;br&gt; technologies. In portable electronics, the battery life time is a major issue, as most of the time the device is accompanied with an&lt;br/&gt;&lt;br&gt; enclosed battery that has to last for long periods without compromise on performance. Furthermore, there are many applications&lt;br/&gt;&lt;br&gt; where the battery lifetime sets the lifetime of the device. Therefore, research is needed to identify the techniques and the impact of&lt;br/&gt;&lt;br&gt; them on the design operated for ultra low-energy. The low energy dissipation requirements on a design are achievable by employing&lt;br/&gt;&lt;br&gt; various optimization techniques. Voltage scaling is the most effective knob to reduce energy dissipation. For this reason ultra-low&lt;br/&gt;&lt;br&gt; energy design usually translates into ultra-low voltage or subthreshold (sub-VT) domain operation. This work presents an analysis&lt;br/&gt;&lt;br&gt; on design space for ultra-low energy dissipation of digital circuits. The circuits are operated in the sub-VT region with moderate&lt;br/&gt;&lt;br&gt; throughput constraints. The drawback of operating circuits in sub-VT is slow speed performances and reduced reliability. To&lt;br/&gt;&lt;br&gt; combat speed degradation due to scaling of the supply voltage, the architectural design space, needs exploration. Techniques such as&lt;br/&gt;&lt;br&gt; device sizing, body biasing, stacking transistors, dual threshold gates, multi threshold synthesis, pipelining, and loop unfolding, are&lt;br/&gt;&lt;br&gt; explored and applied to the designs. The designs are synthesized in a 65 nm CMOS technology with low-power and three threshold&lt;br/&gt;&lt;br&gt; options, both as single-VT and as multi-VT designs. A sub-VT energy model is applied to characterize the designs in the sub-&lt;br/&gt;&lt;br&gt; VT domain. Reliability in the sub-VT domain is analyzed by Monte-Carlo simulations. The minimum reliable operation voltage&lt;br/&gt;&lt;br&gt; (ROV) for gates in low power 65 nm CMOS technology is found to be around 250 mV. The applied energy model for designs to&lt;br/&gt;&lt;br&gt; be characterized for sub-VT domain operation is presented. The energy model encompasses single VT implementations and multi-&lt;br/&gt;&lt;br&gt; VT implementations. The energy modeling is based on the 65 nm CMOS standard cells provided by the technology vendor. The&lt;br/&gt;&lt;br&gt; energy model has been used to evaluate various techniques and constraints for a circuits operated in the sub-VT domain. The work&lt;br/&gt;&lt;br&gt; describes how the energy dissipation of architectures vary w.r.t. switching activity, e. The effects of pipelining together with supply&lt;br/&gt;&lt;br&gt; voltage scaling is analyzed, which shows that they have high benefits with respect to energy dissipation. Various half-band digital&lt;br/&gt;&lt;br&gt; (HBD) filter structures are evaluated for minimum energy dissipation in the sub-VT domain for a throughput constrained system. All&lt;br/&gt;&lt;br&gt; architectures, i.e., unfolded and the basic HBD filter, are implemented and simulated using 65 nm Low-Power High-Threshold (HVT)&lt;br/&gt;&lt;br&gt; standard cells. The application of a sub-VT energy model reveals that it is beneficial to use an unfolded implementation to achieve&lt;br/&gt;&lt;br&gt; low energy dissipation per sample at EMV, when compared to the energy dissipated by a basic simplified HBD filter implementation.&lt;br/&gt;&lt;br&gt; Various available threshold options are analyzed with the help of filter structures by using 65 nm Low-Leakage High-Threshold&lt;br/&gt;&lt;br&gt; (HVT), Standard-Threshold (SVT) and Low-Threshold (LVT) standard cells. Secondly, the design space is increased by utilization&lt;br/&gt;&lt;br&gt; of a combination of HVT + SVT and also HVT + LVT cells. The analysis with sub-VT energy model leads to the conclusion&lt;br/&gt;&lt;br&gt; that a suitable design is a synergy between parallelism, and utilization of various threshold options. In this analysis the multi-VT,&lt;br/&gt;&lt;br&gt; implementations did not show a major advantage over single VT implementations. A decimation filter chain consisting of 4 HBD&lt;br/&gt;&lt;br&gt; filters is fabricated and the silicon measurements demonstrate that SVT and different architectural flavors are suitable for a ultra&lt;br/&gt;&lt;br&gt; low energy (ULE) implementation. Silicon measurements prove functionality down to a supply at 350 mV, with a maximum clock&lt;br/&gt;&lt;br&gt; frequency of 500 kHz, having an energy dissipation of 102 fJ/cycle. Additionally, an alternative to SRAM macro is presented for&lt;br/&gt;&lt;br&gt; sub-VT operations. The memory is based on standard-cells and is referred to as SCMs. The energy per memory access as well as the&lt;br/&gt;&lt;br&gt; maximum achievable throughput in the sub-VT domain of various SCM architectures are evaluated by means of a gate-level sub-VT&lt;br/&gt;&lt;br&gt; energy characterization model.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d24f73b5-fe7a-40f2-90ee-6b81206d9eb1</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="dissertation.pdf">https://portal.research.lu.se/files/3439813/4196460.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4304935</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>CMOS</topic> <topic>ultra low-voltage</topic> <topic>ultra low-energy</topic> <topic>subthreshold (sub-VT)</topic> <topic>body biasing</topic> <topic>pipelining</topic> <topic>unfolding</topic> <topic>half-band digital filter.</topic> </subject> <subject authority="lup"> <topic>Electrical Engineering, Electronic Engineering, Information Engineering</topic> </subject> <relatedItem type="host"> <identifier type="isbn">978-91-7473-725-7</identifier> <identifier type="oldLupId">4196433</identifier> <part> <extent unit="pages"> <total>162</total> </extent> </part> </relatedItem> <relatedItem type="other"> <titleInfo> <title>popsciencePopulärvetenskaplig sammanfattning.pdf</title> </titleInfo> <location> <url>https://portal.research.lu.se/files/3439811/4220160.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> </relatedItem> <note type="teachingLearningHe">yes</note> <dateOther encoding="w3cdtf" type="defenseDate">2014-01-17T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>d24f73b5-fe7a-40f2-90ee-6b81206d9eb1</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:46+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-12-03T13:25:24Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:46+02:00</recordDateApproved> </recordInfo> </mods>

However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. To address this challenge, a novel, polymer-based neural probe, with protrusions tailored to the target tissue, was developed to investigate which probe properties affect the development of a glial scar and neuronal cell death surrounding probes. After many cycles of testing – refinements, promising recordings of neural activity were obtained in both cerebellum&lt;br/&gt;&lt;br&gt; and cortex cerebri (papers I-III). In paper IV, we evaluated the importance of mechanical flexibility and demonstrated that probe flexibility has a significant impact on the astroglial scar, but not on the loss of neurons nearby. Moreover, by embedding the dummy probes in a gelatin matrix that dissolves shortly following implantation, neuronal cell death surrounding chronically (6 weeks) implanted electrodes was, for the first time, abolished. In paper V, sensory processing in primary somatosensory cortex during an episode of hyperalgesia was monitored using implanted neural interfaces in order to further evaluate the probe functionality and usefulness in neurophysiological research. By tracking the development of primary and secondary hyperalgesia as well as allodynia in the sensory cortex, we demonstrate the usefulness of our new neural interface and its capability to differentially and simultaneously record neural signals in different cortical laminae in awake freely moving animals.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1475f06d-05c8-46b7-a5be-30b5d5e1e793</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Per_Kohler_E5.pdf">https://portal.research.lu.se/files/3440349/8597853.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9943592</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Neuronano Research Center (NRC)</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Brain-machine interfaces</topic> <topic>neuroinflammation</topic> <topic>somatosensory cortex</topic> <topic>hyperalgesia</topic> <topic>allodynia</topic> </subject> <subject authority="lup"> <topic>Neurosciences</topic> <topic>Medical Biotechnology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-248-1</identifier> <identifier type="oldLupId">8597852</identifier> <part> <detail type="volume"> <number>2016:25</number> </detail> <extent unit="pages"> <total>76</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-03-04T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>1475f06d-05c8-46b7-a5be-30b5d5e1e793</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:53+02:00</recordDateApproved> </recordInfo> </mods>

Despite extensively research to find curative treatment, no so such therapy exists today. New hypothesis suggests that an aberrant chronic wound healing process takes place which involves both the classical inflammation and more chronic changes of the structural environment where the mesenchymal cell phenotypes such as the fibroblasts play a key role. This phenomenon is defined as airway remodeling and is characterized by a deposition of extracellular matrix (ECM) molecules such as collagens and proteoglycans. Importantly, hitherto available studies have only studied fibroblast from central airways from humans where the role of the fibroblast might be different compared to the distal lung. The aim of the present thesis was to study the different fibroblast phenotypes and their biological role from central and distal localizations from human lung in controls, rhinitis, asthmatics and CODP subjects. Another aim was to investigate the possible origin (circulating progenitor cells) of these cells and thereby highlight the heterogeneity of fibroblast phenotypes resident within the human lung. This investigation demonstrated the novel finding that different fibroblast phenotypes are present in human adult lung. Moreover, they are different in asthma and COPD which suggest disease related fibroblasts that could be of fundamental importance in lung disease.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/53de1d7a-3968-4905-94f6-dbee15cbc71f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="NihlbergKappa.pdf">https://portal.research.lu.se/files/3440399/1398214.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">7707236</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Experimental Medical Science, Lund Univeristy</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Basic Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86253-50-9</identifier> <identifier type="oldLupId">1397355</identifier> <part> <detail type="volume"> <number>2009:62</number> </detail> <extent unit="pages"> <total>131</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-06-12T09:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>53de1d7a-3968-4905-94f6-dbee15cbc71f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:54+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:54+02:00</recordDateApproved> </recordInfo> </mods>

Different theoretical perspectives, research methods as well as various empirical materials have been combined in the re-analysis, in order to achieve an in-depth and composite understanding of collaboration that elucidates its complexity and different dimensions. To this end, I have developed and applied a theoretical grounded analytical model in my study, which combines institutional perspectives with perspectives and concepts from the sociology of law and from theories of power that together illustrate different levels and dimensions. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The analysis shows that the institutionalisation processes include both patterns and variations, i.e., both homogenising and differentiating processes, at different levels, among different Barnahus operations, organisations and collaborative actors. Content and results of collaboration become dependent on the negotiations and power games that emerge among the collaborative actors based on their respective institutional logics. In relation to the collaboration in Barnahus, the tension between the criminal law oriented and the treatment oriented logics comprises the most central one. The analysis has shown how the criminal law logic has gained the priority right of interpretation at the expense of the treatment logic, and also how those collaborative actors, who, in institutional terms, are a part of the treatment logic, have, to a greater extent, adopted a criminal law oriented logic because of their collaboration in Barnahus than vice versa. I have thus noted a general process of juridification, as an institutional change resulting from collaboration, which includes a norm and responsibility shift away from a treatment logic and towards a criminal law logic, which also entails a substantive focus on what has been (ex post) rather than on what will follow (ex ante). More specifically, this implies a focusing on the suspected crimes committed, rather than on investigation of needs and how the children and the families’ future situation can be improved through support and treatment measures. Therefore, in the light of the analysis, there is a risk that the holistic perspective, which based on the collaborative idea is expected to grow actually in practice will diminish through collaboration. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The analysis has cast light on how law becomes part of power and vice versa, and that the forms of power that are actualised in the collaboration assume both clear and diffuse guises that are shaped in an interplay between structure- and actor-oriented power. In the light of the fact that law in a collaborative context contributes to tensions, normative conflicts and dilemmas for the collaborative practice, it also contributes to an uncertainty that characterises the interaction processes and the negotiations that take shape. In negotiations and interaction the law is interpreted according to different logics and acquires its content depending on the forms of power that are actualised and realised in collaboration.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Avhandlingens övergripande syfte är att kritiskt studera interorganisatoriska samverkansprocesser och sammanhängande konsekvenser, med ett särskilt fokus på rättens och maktens betydelse. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Analysen av det empiriska materialet, som speglar samverkan i en kontext av barnahus på sex orter i Sverige (samverkan under ett tak kring utredningar av misstänkta brott mot barn), har genomförts i två steg: en första empirinära analys och en andra teoriförankrad re-analys. I re-analysen har skilda teoretiska perspektiv, forskningsmetoder samt empiriska material kombinerats för att nå en fördjupad och sammansatt förståelse av samverkan som belyser dess komplexitet och olika dimensioner. För detta syfte har jag utvecklat och tillämpat en teoretiskt förankrad analysmodell i min studie som kombinerar institutionella perspektiv med rättssociologiska samt maktteoretiska perspektiv vilka tillsammans illustrerar skilda nivåer och dimensioner. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Analysen visar att institutionaliseringsprocesserna inkluderar både mönster och variationer, det vill säga både homogeniserande och differentierande processer, på olika nivåer, mellan skilda barnahus, organisationer och samverkansaktörer. Innehåll och resultat av samverkan blir beroende av de förhandlingar och maktspel som tar form mellan samverkansaktörerna utefter deras skilda institutionella logiker. I förhållande till barnahusen utgör spänningsförhållandet mellan den straffrättsligt inriktade och den behandlingsinriktade logiken det mest centrala. Analysen har visat hur den straffrättsliga logiken har vunnit tolkningsföreträde på bekostnad av behandlingslogiken, samt hur de samverkansaktörer som institutionellt sett tillhör behandlingslogiken i högre utsträckning har övertagit en straffrättslig logik genom samverkan i barnahus än vice versa. Jag har således kunnat konstatera en generell process av juridifiering, som utgör en institutionell förändring till följd av samverkan, vilken inkluderar en norm- och ansvarsförskjutning från en behandlingslogik i riktning mot en straffrättslig logik, och som innebär en innehållsmässig fokusering på vad som har varit (ex post) snarare än vad som ska följa (ex ante). Mer specifikt innebär det en fokusering på de misstänkt begångna brotten snarare än utredning av behov och hur barnens och familjernas framtida situation kan förbättras genom stöd- och behandlingsinsatser. Därigenom, och i ljuset av vad analysen har påvisat, finns det en risk att helhetsperspektivet som utifrån samverkansidén förutsätts öka i praktiken snarare minskar genom samverkan. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Analysen har speglat hur rätten blir en del av makten och vice versa, samt att de former av makt som aktualiseras i samverkan intar både tydliga och diffusa skepnader som skapas i en växelverkan mellan struktur- och aktörsnära makt. Mot bakgrund av att rätten i en kontext av samverkan bidrar med spänningsförhållanden, normkonflikter och dilemman för samverkanspraktikerna, bidrar rätten också den osäkerhet som präglar samverkansprocesserna och de förhandlingar som tar form. I förhandlingar och interaktion tolkas rätten utefter skilda logiker och får sitt innehåll beroende av de maktformer som aktualiseras och realiseras i samverkan.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8c263aa7-3675-476d-86a5-3af09a9e20f0</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Susanna_Johansson-1.pdf">https://portal.research.lu.se/files/3440437/1856760.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2773177</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>institutional change</topic> <topic>child protection</topic> <topic>social welfare investigations</topic> <topic>crime investigations</topic> <topic>treatment logic</topic> <topic>criminal law logic</topic> <topic>juridification</topic> <topic>power</topic> <topic>institutional theory</topic> <topic>sociology of law</topic> <topic>collaboration</topic> <topic>coordination</topic> <topic>behandlingslogik</topic> <topic>straffrättslig logik</topic> <topic>makt</topic> <topic>institutionell teori</topic> <topic>rättssociologi</topic> <topic>samordning</topic> <topic>samverkan</topic> <topic>institutionalisation</topic> <topic>Barnahus</topic> <topic>brottsutredningar</topic> <topic>sociala utredningar</topic> <topic>barnskydd</topic> <topic>institutionell förändring</topic> <topic>juridifiering</topic> <topic>institutionalisering</topic> </subject> <subject authority="lup"> <topic>Law</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Studies in Sociology of Law</title> </titleInfo> <identifier type="issn">1403-7246</identifier> <identifier type="isbn">978-917473-101-9</identifier> <identifier type="oldLupId">1856753</identifier> <part> <detail type="volume"> <number>35</number> </detail> <extent unit="pages"> <total>253</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-04-15T10:15:00+02:00</dateOther> <recordInfo> <recordIdentifier>8c263aa7-3675-476d-86a5-3af09a9e20f0</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:55+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:55+02:00</recordDateApproved> </recordInfo> </mods>

These tumour-associated macrophages (TAMs) were of the M2 phenotype (CD206+). In CRC patient tissues and xenografts from mouse model, presence of increased amount of M2 macrophages was observed. M2 macrophages derived from human monocyte cell line THP-1 secreted high levels of IL-8 and leukotriene D4 (LTD4), which induced colon cancer cell migration, and Th2 cytokines (IL-4, IL-10) to maintain a tumoral immunosuppressive environment. Remodelling of extracellular matrix (ECM) occurs in CRC. CD47 binding to α2β1 integrin could regulate cyclooxygenase-2 expression and cell migration on collagen I surface in intestinal epithelial cells. CD47 is involved in crosstalk between colon cancer cells and macrophages by interacting with its ligand signal-regulatory protein α on macrophages. This interaction enhanced cell migration of CRC cells and TAMs. IL-8 and LTD4 could induce CD47 expression in CRC cells. Matrix metalloproteinases (MMPs) are enzymes degrading ECM. The enhanced levels of MMP-7 and -9 mRNA expressions and increased cell invasion into matrigel were observed in colon cancer cells upon stimulation with TAM-conditioned medium. These findings provide more evidence that TAMs play an important role in CRC progression. CD47, as a key regulator of crosstalk between colon cancer cells and TAMs, could thus be a therapeutic target for CRC.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Colorectal cancer (CRC) is a cancer caused by uncontrolled cell growth in colon or rectum. CRC is the third most common cancer and the fourth leading cause of cancer related death in the world. It is a multifactorial disease, both genetic predisposition and environmental play a role in the development of CRC. CRC is closely linked to chronic inflammation. Patients with inflammatory bowel disease (IBD) have an increased risk of developing CRC. Tumours are surrounded by the cellular milieu called tumour microenvironment, which is an important hallmark of cancer. In this study, we investigated how colon cancer crosstalk with its microenvironment.&lt;br/&gt;&lt;br&gt; Extracellular matrix (ECM) maintains the morphology of cells, as well as mediates various signalling pathways. Under inflammatory or tumoral conditions, remodelling of ECM often occurs. Matrix metalloproteinases (MMPs) are the predominant ECM-degrading enzymes. MMPs and other factors abound in tumour microenvironment alter ECM synthesis and/or selectively cleave ECM domains. These processes can influence cell proliferation and invasion, failure of cell death, and loss of cell differentiation. When cells are exposed to aberrantly expressed ECM proteins, various downstream signalling pathways will be activated. Signals from ECM can be transduced intracellularly by integrins and CD47. In the first article, CD47, associated with integrin, was shown to play a role in ECM mediated cell migration of intestinal epithelial cells. This increased migration was regulated by inflammatory mediator cyclooxygenase-2 (COX-2).&lt;br/&gt;&lt;br&gt; Macrophages are important phagocytes involved in host defence. They are also major components of inflammatory tumour microenvironment. Tumour cells can recruit macrophages and change their behaviour. These tumour-associated macrophages (TAMs) perform crosstalk between colon cancer cells via CD47 associated with signal-regulatory protein ! (SIRP!). This association and TAM- derived factors was shown to contribute to colon cancer cell migration. TAM-derived factors can also induce mRNA expression and activity of MMPs in colon cancer cells. This might be one explanation how TAMs can induce colon cancer cell invasion.&lt;br/&gt;&lt;br&gt; In summary, these new findings provide an important clue for better understanding of the crosstalk between tumour microenvironment and colon cancers cells, and help to identify new therapeutic targets for colon cancer treatment.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7f4f9cf7-ac9f-4eaf-b82b-bc4ca966267e</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Thesis_Yuan_final_ver.pdf">https://portal.research.lu.se/files/3443513/3972005.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">4114935</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Cell Pathology</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>CD47</topic> <topic>tumour-associated macrophage</topic> <topic>matrix metalloproteinase</topic> <topic>cell migration</topic> <topic>colon cancer</topic> </subject> <subject authority="lup"> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-64-2</identifier> <identifier type="oldLupId">3971997</identifier> <part> <detail type="volume"> <number>2013:92</number> </detail> <extent unit="pages"> <total>104</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-09-05T13:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>7f4f9cf7-ac9f-4eaf-b82b-bc4ca966267e</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:32:59+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:32:59+02:00</recordDateApproved> </recordInfo> </mods>

We describe interactions between streptococcal surface proteins and components of the intrinsic pathway of coagulation and the kallikrein-kinin system in human plasma, as well as to how these surface proteins are produced in different growth phases. The interactions involve activation of the kallikrein-kinin system and inhibition of its antibacterial effects. Inspired by these results, we review the literature, and develop a general model of streptococcal virulence. According to this model, the bacteria have two strategies, which we call asymptomatic colonization and superficial symptomatic infection, respectively, and they are adaptive under different epidemiological conditions. We propose that the bacteria&apos;s ability to cause invasive infections, which are the best studied, because they are the most severe, is a side effect of traits that evolved as adaptations for superficial symptomatic infections. This implies that many virulence mechanisms that have been described in invasive infections should have their functions in superficial symptomatic infections. We therefore investigate one such mechanism–the activation of host plasminogen–in conditions simulating pharyngitis, a very common superficial streptococcal infection. Pharyngitis is characterized by the exudation of plasma into an environment with saliva. We find that saliva affects the initiating enzymes of the intrinsic pathway of coagulation, and that this results in the formation of clots that entrap the bacteria. The bacteria escape the clots by activating host plasminogen, a finding that is in concordance with the model. As a whole this thesis underscores the utility of evolutionary analysis for interpreting and guiding mechanistic studies in infection biology, and conversely, the usefulness of mechanistic input for evolutionary theorizing.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Vi har undersökt hur och varför streptokocker orsakar sjukdom. Vi började med att undersöka hur proteiner på bakterieytan interagerar med det så kallade kontaktsystemet, som är en del av immunförsvaret och blodlevringen. Vi fann att det bildades en inflammatorisk signalmolekyl och ett bakteriedödande proteinfragment men bakteriens ytproteiner skyddade mot det. Att bakterier både utlöser ett immunsvar (inflammation) och skyddar mot detsamma är ett återkommande tema i studier av hur bakterier orsakar sjukdom, inte minst allvarliga invasiva infektioner. Och ofta verkar det vara så att bakterierna aktivt sätter igång immunsystemet, snarare än bara blir attackerade av det. Det kan verka motsägelsefullt att bakterierna både sätter igång immunsvaret och motverkar det. Dessutom är invasiva infektioner en återvändsgränd för bakterierna, eftersom de inte sprider sig vidare från sådana infektioner, så det är märkligt att bakterierna verkar så väl anpassade för dem. Vi fortsatte därför med att utveckla en teoretisk modell för att förklara evolutionärt varför bakterierna har dessa egenskaper, varför de både sätter igång inflammationen och försvarar sig mot den. I korthet går modellen ut på att det naturliga urvalet gynnar dessa egenskaper, eftersom inflammationen ökar mängden tillgänglig näring för bakterierna när de växer på till exempel halsslemhinnan. Detta kan de utnyttja för att växa och sprida sig, men bara om de samtidigt kan skydda sig mot de antibakteriella komponenterna av inflammationen. Ett exempel på en infektion där streptokocker orsakar inflammation och sprids snabbt från infektionen är halsfluss. Detta kan förklara varför streptokockerna interagerar med immunsystemet på det sätt de gör och varför de har de egenskaper som krävs för det. Oturligt nog fungerar immunförsvaret ungefär likadant i invasiva infektioner som det gör i halsfluss. Därför kan bakterier som är anpassade till halsfluss manipulera immunförsvaret i invasiva infektioner också. Det är en ren bieffekt av bakteriens egenskaper och anpassningar, en väldigt viktig och olycklig bieffekt. Enligt modellen ska alltså bakteriella egenskaper som är viktiga i invasiva infektioner ha sina egentliga funktioner i mer lindriga infektioner som till exempel halsfluss. Vi tillämpade det tänkesättet genom att undersöka streptokockernas förmåga att aktivera plasminogen (ett enzym som löser upp levrat blod och blodplasma). Det är välkänt att den förmågan är viktig vid invasiv sjukdom. Vi beskriver en funktion för den förmågan vid halsfluss. Sammantaget understryker avhandlingen värdet av att kombinera evolutionära och (bio)medicinska perspektiv i studiet av infektioner.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/b6808b0a-7b4b-4c55-af96-75696b953af5</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_KWW_g5.pdf">https://portal.research.lu.se/files/3443997/4145103.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">506503</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kww_framsida.pdf">https://portal.research.lu.se/files/3443999/4145105.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1840592</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Infection Medicine</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Streptococci</topic> <topic>virulence</topic> <topic>coagulation</topic> <topic>intrinsic pathway</topic> <topic>evolution</topic> </subject> <subject authority="lup"> <topic>Infectious Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-93-2</identifier> <identifier type="oldLupId">4145098</identifier> <part> <detail type="volume"> <number>2013:120</number> </detail> <extent unit="pages"> <total>100</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-11-22T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>b6808b0a-7b4b-4c55-af96-75696b953af5</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:03+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:03+02:00</recordDateApproved> </recordInfo> </mods>

Obesity, which dramatically increases worldwide, is associated with&lt;br/&gt;&lt;br&gt; insulin resistance and T2D. In this thesis, we elucidate the effects of hormones and&lt;br/&gt;&lt;br&gt; nutrients on biological responses and regulatory mechanisms in pancreatic β-cells&lt;br/&gt;&lt;br&gt; and adipocytes. The information is scarce with regard to the regulation of cyclic&lt;br/&gt;&lt;br&gt; nucleotide phosphodiesterase 3B (PDE3B) in pancreatic β-cells. We show that&lt;br/&gt;&lt;br&gt; PDE3B is activated in response to glucose, insulin and forskolin, which is coupled&lt;br/&gt;&lt;br&gt; to a decrease, no apparent change or an increase in total phosphorylation of the&lt;br/&gt;&lt;br&gt; enzyme in rat pancreatic β-cells. Furthermore, PDE1A, PDE3, PDE4C, PDE5A,&lt;br/&gt;&lt;br&gt; PDE7A, PDE7B, PDE8A, PDE10A and PDE11A are detected in human&lt;br/&gt;&lt;br&gt; pancreatic islets. Islets from RIP-PDE3B mice, exhibiting β-cell specific&lt;br/&gt;&lt;br&gt; overexpression of the cAMP-degrading enzyme phosphodiesterase 3B (PDE3B)&lt;br/&gt;&lt;br&gt; and dysregulated insulin secretion, show induced OPN protein expression. In&lt;br/&gt;&lt;br&gt; addition, in silico and functional approaches demonstrate that PDE3B and OPN&lt;br/&gt;&lt;br&gt; are connected and follow a similar protein expression pattern in response to e.g.&lt;br/&gt;&lt;br&gt; cAMP-elevating agents and insulin. Little is known regarding the direct effects of&lt;br/&gt;&lt;br&gt; short-chain fatty acids (SCFAs), produced through bacterial fermentation of&lt;br/&gt;&lt;br&gt; dietary fibers, on glucose and lipid metabolism in adipocytes. We show that the&lt;br/&gt;&lt;br&gt; SCFAs propionic acid and butyric acid inhibit cAMP-stimulated lipolysis, a&lt;br/&gt;&lt;br&gt; mechanism that is not dependent on the cAMP-degrading enzyme PDE3B.&lt;br/&gt;&lt;br&gt; Moreover, both SCFAs inhibit basal and insulin-stimulated de novo lipogenesis,&lt;br/&gt;&lt;br&gt; which is associated with increased phosphorylation of acetyl CoA carboxylase, the&lt;br/&gt;&lt;br&gt; rate-limiting enzyme in fatty acid synthesis. Propionic acid and butyric acid are&lt;br/&gt;&lt;br&gt; also able to potentiate insulin-stimulated glucose uptake.&lt;br/&gt;&lt;br&gt; In summary, we demonstrate that agents relevant for β-cell function regulate&lt;br/&gt;&lt;br&gt; PDE3B activity and phosphorylation levels. Based on several strategies, we&lt;br/&gt;&lt;br&gt; demonstrate a connection between PDE3B and OPN, the latter having a protective&lt;br/&gt;&lt;br&gt; role in pancreatic β-cells. Further investigations are required to identify&lt;br/&gt;&lt;br&gt; downstream targets of PDE3B that are involved in the regulation of insulin&lt;br/&gt;&lt;br&gt; exocytosis and also to elucidate the relationship with OPN. Moreover, several&lt;br/&gt;&lt;br&gt; PDEs are present in human pancreatic islets. The majority of these PDEs have&lt;br/&gt;&lt;br&gt; been described as insulin secretagogues in animal models and it is thus promising&lt;br/&gt;&lt;br&gt; to also confirm their presence in humans, as it can be advantageous for the&lt;br/&gt;&lt;br&gt; 8&lt;br/&gt;&lt;br&gt; treatment of T2D. SCFAs inhibit fatty acid mobilization and potentiates insulininduced&lt;br/&gt;&lt;br&gt; glucose uptake; observed effects that might be beneficial for preventing&lt;br/&gt;&lt;br&gt; ectopic lipid accumulation, lipotoxicity and insulin resistance. Thus, it remains to&lt;br/&gt;&lt;br&gt; be verified if anti-obesity properties can be conferred to SCFAs.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Typ 2-diabetiker: söt som socker och rik på fett&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Det finns flera olika varianter av diabetes och den mest förekommande är typ 2-diabetes (T2D). T2D kallades förr i dagligt tal åldersdiabetes, men numera drabbas individer i alla åldrar. Sjukdomen kännetecknas av förhöjda nivåer av socker och&lt;br/&gt;&lt;br&gt; fett i blodet, vilket beror på att kroppens celler har en nedsatt förmåga att tillgodose sitt energibehov. Bakomliggande orsaker förknippas med olika faktorer, till exempel genetisk bakgrund, ohälsosamma kostvanor och fysisk inaktivitet. Individer med fetma har en ökad fettansamling, som i vissa fall är förknippad med&lt;br/&gt;&lt;br&gt; allvarliga hälsoproblem, såsom nedsatt förmåga att ta upp socker i närvaro av insulin och uppkomst av T2D. Det är inte helt klarlagt vad som orsakar den starka kopplingen mellan fetma och T2D, men fettinlagring i vävnader som inte är ämnade att lagra fett, exempelvis lever och muskulatur, samt kronisk inflammation&lt;br/&gt;&lt;br&gt; och förändrade nivåer av cirkulerande hormoner som härrör från fettväven antas vara bidragande faktorer.&lt;br/&gt;&lt;br&gt; Betacellen fungerar som en sensor som känner av blodsockernivån och därefter frisätter en viss mängd insulin för att justera blodsockret efter en måltid. Insulin har en livsnödvändig roll då kroppens celler tillgodoser energibehovet genom att&lt;br/&gt;&lt;br&gt; understöjda energiupptag och lagring av socker som glykogen i lever och skelettmuskulatur, samt fett som triacylglyceroler i fettväven. Samtidigt som det sker en lagring av energi dämpar insulin nedbrytningen av de energilager som redan finns. Eftersom socker är en av de viktigaste energikällorna för kroppen, och&lt;br/&gt;&lt;br&gt; dessutom den enda energikällan för hjärnan, är det viktigt att upprätthålla en stabil sockernivå i blodet. När nivåerna av socker sjunker i blodet återställs sockerbalansen genom att alfacellerna i bukspottkörteln utsöndrar glukagon, som&lt;br/&gt;&lt;br&gt; stimulerar levern att frigöra lagrat socker till blodbanan. Hos diabetiker utsöndras inte insulin i tillräckliga mängder och det insulin som cirkulerar i blodbanan har en&lt;br/&gt;&lt;br&gt; försämrad verkan i fettväv, lever och muskulatur. Den ökade frisättningen av fettsyror och den vid fetma förändrade hormonella utsöndringen från fettväven bidrar till inflammation, och till att insulinkänsligheten försämras ytterligare.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studier i de Langerhanska öarna och i betaceller&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I bukspottkörteln finns det olika sorters celler som bildar grupperingar, så kallade Langerhanska öar. Betacellen är en av flera celltyper i de Langerhanska öarna och är som tidigare beskrivits den cell som producerar insulin. I första och andra&lt;br/&gt;&lt;br&gt; delarbetet har de Langerhanska öarna tagits ut från bukspottkörteln och använts för att bland annat studera hur ett flertal enzymer och proteiner påverkas under olika betingelser. Eftersom vi främst är intresserade av att studera betacellen, har vi även använt oss utav odlade celler som efterliknar betacellens förmåga att&lt;br/&gt;&lt;br&gt; producera insulin.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Konsten att kontrollera PDE3B (delarbete I)&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; När sockernivån ökar i blodet, vilket sker efter en måltid, känner betacellerna av det, vilket resulterar i att en signaleringsväg aktiveras inne i cellen som slutligen leder till insulinutsöndring i blodet. I betacellen finns även andra signaleringsvägar&lt;br/&gt;&lt;br&gt; som ytterligare förstärker frisättningen av insulin. cAMP är en signalmolekyl som till exempel förstärker effekten av insulinfrisättningen genom att signalera till&lt;br/&gt;&lt;br&gt; andra molekyler i de olika signaleringsvägarna. Enzymer fungerar som&lt;br/&gt;&lt;br&gt; katalysatorer genom att öka eller minska hastigheten på kemiska reaktioner och på så vis omvandla ett ämne till ett annat i cellen. För att kontrollera nivåerna av cAMP, finns det särskilda enzymer, så kallade fosfodiesteraser (PDE), som har till&lt;br/&gt;&lt;br&gt; uppgift att ombilda cAMP till ett annat ämne. Fosfodiesteraser består av en stor grupp närbesläktade proteiner som är indelade i&lt;br/&gt;&lt;br&gt; elva olika familjer (PDE1-11). Ett särskilt fokus har tilldelats familjen PDE3 i betacellen, där den specifika familjemedlemmen PDE3B har studerats i detalj. Man har i tidigare studier konstaterat att PDE3B är involverat i regleringen av&lt;br/&gt;&lt;br&gt; insulinutsöndringen från betacellen. Det är därför betydelsefullt att ta reda på hur PDE3B kan styras för att det i sin tur ska kunna påverka nivåerna av signalmolekylen cAMP. I de studier vi har bedrivit fann vi att PDE3B aktiverades,&lt;br/&gt;&lt;br&gt; vilket leder till ökad ombildning av cAMP, i närvaro av bland annat socker, insulin och förhöjda nivåer av cAMP. Vi studerade vidare ifall aktivering av PDE3B var kopplat till fosforylering av enzymet, vilket innebär att en fosfatgrupp&lt;br/&gt;&lt;br&gt; sätts fast på specifika ställen på PDE3B. Det visade sig att aktivering av PDE3B sammanföll med varierande grad av fosforylering. Som tidigare omnämnts är PDE3B i sitt aktiva tillstånd benägen att bryta ner cAMP i betacellen. Att på ett&lt;br/&gt;&lt;br&gt; fördjupat plan förstå hur olika betingelser kan styra PDE3B till ett mer eller mindre aktivt läge är betydelsefullt, eftersom en dämpad aktivitet av PDE3B leder till en ökad frisättning av insulin. Vidare studier krävs för att utreda vilka specifika&lt;br/&gt;&lt;br&gt; proteiner som styr PDE3B eftersom det kan ha betydelse för regleringen av cAMP och därmed insulinfrisättningen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; PDE-familjernas existens i människans Langerhanska öar (delarbete I)&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Tidigare studier har visat att andra medlemmar inom de olika PDE-familjerna har benägenhet att påverka insulinfrisättningen, eftersom en hämmad aktivitet av de olika PDE-medlemmarna ger en ökad utsöndring av insulin. Men med den begränsade tillgången till humant material, är det få studier som visar existensen&lt;br/&gt;&lt;br&gt; av PDE-familjerna i de Langerhanska öarna från enskilda individer. Genom tillgång till Langerhanska öar från det nordiska nätverket för klinisk ötransplantation,som forskarna inom ”Lund University Diabetes Centre” (LUDC) har ett nära samarbete med, fick vi möjlighet att studera ett urval av PDEfamiljerna&lt;br/&gt;&lt;br&gt; i material från människor. Vi fann att PDE1, PDE3 och PDE4 är i aktivt läge och att de mer specifika PDE-medlemmarna PDE4C, PDE7A, PDE8A och PDE10A existerar i de Langerhanska öarna. Vidare studier krävs för att utreda hur dessa PDE-medlemmar kan styras i betacellen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den sociala sfären för PDE3B (delarbete II)&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den roll som PDE3B har i betacellen har tidigare studerats i en specifik mus med förhöjda nivåer av PDE3B i betacellerna, vilket leder till att en mindre mängd insulin frisätts till blodet. I musens Langerhanska öar syns också en uttalad förändring med tanke på hur de olika celltyperna är lokaliserade, vilket kan påverka frisättningen av olika hormoner, t.ex. insulin, negativt. Musen är också mer benägen att utveckla insulinresistens (sämre verkan av insulin i målvävnaderna), och den har onormalt höga nivåer av socker i blodet efter att ha fått en diet rik på fett. Vi har studerat den information som behövs för tillverkning&lt;br/&gt;&lt;br&gt; av proteiner för att utreda hur förhöjda nivåer av PDE3B kan påverka den inre miljön i betacellen. Resultatet visade att den specifika informationen för proteinet osteopontin fanns i större mängder i möss med förhöjda nivåer av PDE3B. Osteopontin identifierades för första gången i ben (gr. osteon, ”ben” och lat. pons,”bro”). I andra studier har man visat att osteopontin är kopplat till olika komplikationer vid diabetes, och i betacellen skyddar den till exempel mot giftiga ämnen som kan påverka vår arvsmassa negativt. Att osteopontin just är ett brobyggande protein fick vi konstaterat i arbetet, osteopontin socialiserar nämligen&lt;br/&gt;&lt;br&gt; med PDE3B i ett stort nätverk av proteiner. Vi fann även att mängden PDE3B och OPN följdes åt i olika miljöer. Vidare studier krävs för att utreda hur väl PDE3B och OPN samverkar i betacellen.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studier i fettceller&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; I kroppen finns det olika sorters fettdepåer, som antingen är belägna under huden (underhudsfett) eller kring de inre organen och i bukhålan (visceralt fett). Fettdepåer utgör både ett isolerande och mekaniskt skydd samt tillgodogör&lt;br/&gt;&lt;br&gt; kroppen med den energi som finns lagrad i fettcellerna (även kallade adipocyter). I delarbete III har vi tagit ut fettdepån runt bitestikeln från råtta och isolerat fettceller för att studera hur olika komponenter från födan kan påverka kroppens energireserv.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Rätt fett gör dig nätt (delarbete III)&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Överviktiga med ökade nivåer av fettsyror i blodbanan har ofta en försämrad verkan av insulin vid sockerupptag till cellerna, och löper därför större risk att utveckla T2D. Men med förbättrade levnadsvanor, där en balanserad kost och aktivt liv står i fokus, kan man förbättra hälsan avsevärt och till och med i vissa&lt;br/&gt;&lt;br&gt; fall utesluta medicinering och tillförsel av insulin.&lt;br/&gt;&lt;br&gt; Det är till exempel väl etablerat att ett högt kostfiberintag förbättrar ämnesomsättningen genom att till exempel sänka socker- och kolesterolnivåerna i blodet. Kostfiber består av kolhydrater som inte är tillgängliga för nedbrytning i tunntarmen. I tjocktarmen däremot tas kostfiber väl om hand av bakterier, vilket&lt;br/&gt;&lt;br&gt; resulterar i att kortkedjiga fettsyror produceras. Det finns ett flertal varianter på kortkedjiga fettsyror, men de vanligaste är ättiksyra, propionsyra och smörsyra. Ett flertal studier indikerar att det är de korta fettsyrorna som har de hälsobringande&lt;br/&gt;&lt;br&gt; effekterna på kroppen, snarare än kostfiber i sin helhet. Det har till exempel visats sig att de kortkedjiga fettsyrorna skyddar mot djurfetma, vilket även åtföljs av lägre nivåer av socker och fett i blodbanan. Huruvida de kortkedjiga fettsyrorna&lt;br/&gt;&lt;br&gt; påverkar olika målvävnader, såsom muskulatur och fettväv i kroppen är inte helt klarlagt. I delarbete III har vi därför studerat effekterna av propionsyra och smörsyra på fettcellens förmåga att hantera sockerupptag och mobilisera energi i form av fettsyror. Våra fynd visar att kortkedjiga fettsyror hämmar både&lt;br/&gt;&lt;br&gt; produktion av långa fettsyror och nedbrytning av triacylglyceroler, vilket i det långa loppet skulle ge lägre nivåer av fettsyror i blodbanan. Att öka förmågan hos&lt;br/&gt;&lt;br&gt; fettcellerna att hämma nedbrytningen av fett är viktigt med tanke på att ökade nivåer av fettsyror i blodbanan försämrar kroppens insulinkänslighet och leder till fettansamling i andra organ än i fettväven. De kortkedjiga fettsyrorna förbättrade&lt;br/&gt;&lt;br&gt; även insulinets förmåga att stimulera upptag av socker till fettcellerna, en mekanism som är försämrad hos individer med fetma och T2D. Det kvarstår att utreda hur de kortkedjiga fettsyrorna på ett mer detaljerat plan påverkar fettcellens förmåga att lagra och mobilisera energi till kroppens övriga vävnader. De gynnsamma effekterna som uppvisats för de kortkedjiga fettsyrorna inger däremot en förhoppning att i framtiden kunna utveckla läkemedel för att förhindra uppkomst av övervikt och T2D.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattning&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Sammanfattningsvis har studier bedrivits för att utreda uttryck och reglering av olika PDE-medlemmar samt för att finna kopplingar mellan PDE3B och andra proteiner som inverkar på betacellens funktion, vilken är att upprätthålla en fungerande insulinfrisättning. Vidare gjordes studier i fettceller för att utreda kortkedjiga fettsyrornas effekter på mobilisering och lagring av energi. Detta är framför allt aktuellt för många överviktiga och diabetiker, eftersom de är i allra&lt;br/&gt;&lt;br&gt; högsta grad ”söta som socker och rika på fett” och därmed i första hand behöver förbättra sitt energiupptag.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/c3a53609-2361-455e-a5fc-810dabfac6f3</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="140514_Mediatryck_Emilia_Heimann.pdf">https://portal.research.lu.se/files/3444023/4437823.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2187516</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="70516_Emilia_Heimann_OMSLAG_2.pdf">https://portal.research.lu.se/files/3444025/4437824.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">9250703</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Insulin Signal Transduction</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Obesity</topic> <topic>type 2 diabetes</topic> <topic>islets of Langerhans</topic> <topic>adipocytes</topic> <topic>PDE3B</topic> <topic>OPN</topic> <topic>SCFAs</topic> </subject> <subject authority="lup"> <topic>Endocrinology and Diabetes</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-7619-002-9</identifier> <identifier type="oldLupId">4437821</identifier> <part> <detail type="volume"> <number>2014:73</number> </detail> <extent unit="pages"> <total>150</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-06-04T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>c3a53609-2361-455e-a5fc-810dabfac6f3</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:03+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:03+02:00</recordDateApproved> </recordInfo> </mods>

There is, however, a lack of knowledge in several&lt;br/&gt;&lt;br&gt; respects. The overall aim of this thesis was to study outcomes in terms of occupational performance, satisfaction with performance, psychosocial functioning, disability, and coping profiles at a one-year follow-up after a musculoskeletal pain rehabilitation programme. Part of the aim was to evaluate differences among subgroups of participants based on baseline characteristics and pain-related severities, regarding the above described outcomes. Better psychosocial functioning and less severe disability were in a sample of 509 individuals (Paper I) associated with: older age, being at work prior admission, being Nordic born, longer education, a diagnosis of fibromyalgia (compared with neck disorder or low back pain). At a one-year follow-up psychosocial functioning was significantly improved whereas less improvement was found in physical disability. Improvements at one-year follow-up were independently of participants’ characteristics. The participants’ prioritized occupational problems in all sorts of occupations pertaining to looking after one self (self-care), enjoying&lt;br/&gt;&lt;br&gt; life (leisure), and contributing to the social and economic fabric of a Community (productivity). The most prioritized subcategory of occupations to be improved on was household management (Paper II). The most frequently reported occupations were reported as: working, sitting and cleaning the house. Occupational performance and satisfaction with performance improved significantly at discharge and at the follow-up (Paper III). Improvements on occupational&lt;br/&gt;&lt;br&gt; performance at follow-up were significantly associated with the following factors: female gender, less physical disability, less life interference and more life Control at baseline. However, participants with most perceived severities to perform their prioritized occupations had significantly higher chance to be improved. The pain coping profiles of Adaptive Copers significantly increased at the follow-up, whereas the Dysfunctional profiles significantly decreased (Paper IV). Having an Adaptive Coper profile at follow-up was associated with improvement on occupational performance and was significantly associated with: being Nordic born, having a longer education and an Adaptive Coper profile and higher scores on satisfaction with occupational performance at baseline. Having an Adaptive Coper profile at follow-up was significantly associated with improvements on occupational performance and satisfaction with performance.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Interdisciplinära smärtrehabiliteringsprogram har visat bättre resultat än mindre intensiva åtgärder. Det saknas dock kunskap inom flera olika områden. Denna avhandling har bland annat fokuserat vilka aktivitetsproblem som personer som&lt;br/&gt;&lt;br&gt; genomgått ett sådant program upplever viktigast att förbättra. Alla deltagarna i programmet hade långvarig muskuloskeltal smärta med komplexa negativa konsekvenser för deras vardagsliv. Vi har undersökt hur personer som genomgått ett smärtrehabiliteringsprogram skattar sin hälsa före rehabiliteringen, vid avslut och ett år efter deltagandet i programmet. Aktivitetsförmåga och tillfredställelse med denna har skattats i de aktiviteter som deltagarna själva har rapporterat som&lt;br/&gt;&lt;br&gt; mest betydelsefulla. Vi undersökte vilka de viktigaste aktivitetsproblemen var och om dessa aktivitetproblem var olika för olika grupper av deltagare. Psykosociala faktorer, rapporterad förmåga i förutbestämda fysiska aktiviteter, fysisk &lt;br/&gt;&lt;br&gt; aktivitetsnedsättning, och rapporterad förmåga att hantera smärtan, sk copingförmåga har också fokuserats. Vi har också undersökt om det finns grupper av deltagare som mår sämre vid rehabiliterings start eller som uppvisar sämre resultat efter ett år. De sociodemografiska grupperingar som användes var: kön,ålder, födelseland norden eller utanför norden, utbildningsgrad, om man var i arbete före rehabiliteringen eller inte samt civilstånd. Vi grupperade deltagarna&lt;br/&gt;&lt;br&gt; efter olika diagnosgrupper och undersökte om smärtdurationen hade betydelse för måendet eller för förändringarna vid ett års uppföljningen. Deltagarna hade ett brett utbud av aktivitetsproblem som de ville ha hjälp att hitta&lt;br/&gt;&lt;br&gt; strategier för att klara av. Dessa aktivitetsproblem visade sig vara olika för männen och kvinnorna. Kvinnorna hade huvudsakligen problem att utföra sysslor relaterade till hushållet eller arbetet, medan männen rapporterade mer problem&lt;br/&gt;&lt;br&gt; relaterade till personlig vård och förflytting. Deltagarna hade problem inom alla olika aktivitetsområden, personlig vård, arbete och hushållsarbete och fritidsaktiviteter. Att arbeta, att sitta och att städa var de enskilda problem som&lt;br/&gt;&lt;br&gt; rapporterades mest, medan flest problem fanns inom gruppen hushållsgöromål. Deltagarna beskriver en förbättrad förmåga att utföra de aktiviteter i sin vardag som är mest meningsfulla för dem och ännu fler var mera nöjda med hur de klarade av att utföra dessa deras viktigaste vardagsgöromål. Vi hittade också signifikant förbättrade värden på gruppnivå såväl vid avslut som efter ett år, förbättringarna i utförandet fortsatte att öka efter programmets avslut. Deltagarna beskrev positiva förändringar avseende smärtans intensitet, känslomässigt mående och upplevd kontroll ett år efter programmet. Smärtdurationen, diagnosgrupp eller sociodemografiska faktorer påverkade inte resultaten avseende psykosocial&lt;br/&gt;&lt;br&gt; funktion eller fysisk aktivitetsnedsättning. Civilstånd, ålder, diagnos eller smärtduration hade ingen betydelse för resultaten vid ett års uppföljningen. Männens tillfredsställelse med sin aktivitetsförmåga förbättrades dock i mindre&lt;br/&gt;&lt;br&gt; grad än kvinnornas. Självrapporterat fysiskt funktionshinder, relaterat till fysiska aktiviteter som deltagarna inte hade prioriterat själva, förbättrades i mycket liten omfattning. Deltagare som rapporterade större fysiskt funktionshinder och sämre psykosocial funktion initialt hade dock mindre chans att förbättra sin aktivitetsförmåga. Medan personer med mer problem i de egenprioriterade aktiviteterna förbättrades mer än de som hade mindre problem i dessa. Personer som inte var födda i norden, hade lägre utbildning och som inte var i arbete hade sämst psykosocial funktion före rehabiliteringen. Dessa resultat tyder på att grupper av personer kan behöva en mera anpassad rehabilitering eller rehabilitering&lt;br/&gt;&lt;br&gt; med delvis annat innehåll än den som idag finns. Copingförmågan förbättrades signifikant efter ett år och en bra copingförmåga vid uppföljningen var associerat med förbättrad aktivitetsförmåga i egenprioriterade aktiviteter. Däremot var det en stor grupp deltagare som ett år efter programmet fortfarande inte tillhörde gruppen ”adaptiv coper”, dvs den grupp som beskrivs ha bäst copingförmåga. Flera av deltagarna som inte tillhörde denna coping-grupp efter ett år hade ändå förbättrat sin aktivitetsförmåga. Personer med lägst utbildning och som inte var födda i norden hade minst chans att förbättra sin coping förmåga. Personer som beskrev sämst socialt stöd förändrade sin copingförmåga minst. Sambandet mellan förbättrad coping, ”tänkade” och förbättrad aktivitetsförmåga, ”görande”, är intressant. Detta samband behöver&lt;br/&gt;&lt;br&gt; undersökas vidare för att vi bättre ska förstå vilka processer under en rehabilitering, ”görande” respektive ”tänkande”, som hjälper olika grupper av personer och hur dessa processer är relaterade till varandra. ”Görandet” verkar&lt;br/&gt;&lt;br&gt; förbättras för fler deltagare än ”tänkandet”. Vissa deltagare verkar vara i behov av mera individualiserade eller anpassade&lt;br/&gt;&lt;br&gt; åtgärder för att förbättras. Personer med ländryggsmärta och nackrelaterad smärta verkar också ha mer problem relaterat till aktivitetsförmåga eller fysisk funktionshinder än vad deltagare med fibromylagi har. Sammanfattningsvis visar resultaten på förbättringar som också bibehålls ett år efter rehabiliteringen, ibland fortsätter förbättringen till och med att öka efter avslut. Det finns grupper av deltagare som verkar behöva mera anpassade åtgärder än vad programmet har&lt;br/&gt;&lt;br&gt; erbjudit. Det verkar också finnas behov av att undersöka samband mellan förbättringar i olika utfallsmått mera ingående.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7af966cd-1f68-45c4-9dbd-5c1901b05c63</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Elisabeth_e-spik_avh_1_.pdf">https://portal.research.lu.se/files/3445237/4359167.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2923763</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Rehabilitation medicine</publisher> <dateIssued encoding="w3cdtf">2014</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Activities of Daily living</topic> <topic>rehabilitation</topic> <topic>chronic pain</topic> <topic>pain management</topic> <topic>treatment outcome</topic> <topic>disability evaluation</topic> <topic>coping behavior</topic> <topic>occupational therapy</topic> <topic>fibromyalgia</topic> </subject> <subject authority="lup"> <topic>Other Medical and Health Sciences not elsewhere specified</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-64-9</identifier> <identifier type="oldLupId">4359166</identifier> <part> <detail type="volume"> <number>2014:39</number> </detail> <extent unit="pages"> <total>222</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2014-04-04T09:00:00+02:00</dateOther> <recordInfo> <recordIdentifier>7af966cd-1f68-45c4-9dbd-5c1901b05c63</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:19+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:19+02:00</recordDateApproved> </recordInfo> </mods>

The broad aim of this is to contribute to the solution of the ‘drumlin problem’. The term drumlin has come to be applied to a wide range of features whose internal architecture (core) and overall morphology are seen to vary greatly. This range in characteristics is in part responsible for the various competing theories of drumlin formation, each different type of core and morphology generating a new idea for how it came about. &lt;br/&gt;&lt;br&gt; Here the new Swedish national height model, a high resolution LiDAR derived digital elevation model, in combination with detailed sedimentological work is used to characterise streamlined terrain in southern Sweden and investigate the formation processes associated with it. &lt;br/&gt;&lt;br&gt; The findings of this are that drumlinoids in southern Sweden are predominantly rock cored. Soft cored features tend to be significantly longer than rock cored features. In general, drumlinoids in southern Sweden are located at the lower end of the size spectrum in terms of global streamlined sub-glacial features. Additionally it has been found that drumlinoids can form rapidly at glacial margins as well as within the main body of ice sheets. And finally, the most important contextual geological factor in drumlinoid parameter (morphology) formation appears to be drift depth/properties. The bedrock type beneath a feature and the hydrological system as recorded in eskers do play a role, but the exact nature of this is not certain and the correlations are difficult to analyse.&lt;br/&gt;&lt;br&gt; In addition to these findings a generalised conceptual model of drumlinoid formation is proposed and a discussion of the possible ways in which physical processes influence said formation is offered. It is suggested that chaotic behaviour and the role of scale might be useful to consider and that whilst it is something of semantic point, the use of the term drumlinoid is deliberate and important. This is because due to equifinality there are many landforms that researchers can split into different categories, e.g. rock drumlins, clone drumlins, emergent drumlins, downwards emergent drumlins or obstacle drumlins. These are all valid divisions as there are different physical processes involved in their formation. However these processes and the final landforms that result from them are all part of the sub-glacial continuum and so at one level must be considered part of the same family.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Denna avhandling behandlar strömlinjeformade subglaciala bäddformer (ofta kallade drumliner) i södra Sverige. Det övergripande syftet med denna studie är att bidra till en lösning av det så kallade ”drumlinproblemet”. Termen drumlin har kommit att tillämpas på en grupp av landformer vars interna sediment, strukturella uppbyggnad och yttre form kan variera kraftigt. Dessa variationer i egenskaper är delvis förklaringen till de olika konkurrerande teorier som lagt fram om drumlinbildning; ofta har varje typ av beskriven intern sammansättning och/eller yttre morfologi genererat nya/andra tankar om hur drumlinbildningen i det speciella fallet gått till. På grund av mångfalden i föreslagna processer föredrar jag att benämna landformsgruppen som drumlinoider (’drumlin-liknande’).&lt;br/&gt;&lt;br&gt; I denna studie har ett viktigt hjälpmedel varit den nya svenska nationella höjdmodellen baserad på LiDAR-data från vilken vi kan generera digitala högupplösta digitala höjdmodeller. Detta har kombinerats med detaljerad sedimentologiska undersökningar för att karakterisera strömlinjeformad terräng i södra Sverige och undersöka bildningsprocesser i samband med drumlinoidernas uppbyggnad.&lt;br/&gt;&lt;br&gt; Resultaten av mina undersökningar visar att drumlinoider i södra Sverige är dominant uppbyggda kring en fast bergkärna. Drumlinoider som uppvisar sedimentkärnor tenderar att vara betydligt längre än bergkärnedrumlinoider. I allmänhet ligger drumlinoidformer i södra Sverige i den nedre delen av det storleksspektra som drumlinoider uppvisar inom tidigare nedisade områden i ett globalt kontext. Vidare visar vi att drumlinoider kan bildas under ett kort tidsintevall både i mycket israndnära lägen och längre in under inlandsisen. Den viktigaste kontextuella parametern för drumlinoidbildning verkar vidare vara egenskaperna på och mäktigheten av det underlag i vilka drumlinoidera utformas. Typen av berggrund och det hydrologiska systemet under inlandsisen, som det reflekteras förekomsten av rullstensåsar verkar också spela en viss roll, men den exakta betydelsen av dessa faktorer är inte säker och sambanden är svåra att analysera.&lt;br/&gt;&lt;br&gt; Utöver dessa resultat föreslås en generaliserad konceptuell modell för bildning av drumlinoider kring vilken en diskussion förs om på vilka möjliga sätt olika fysikaliska processer kan påverkar denna bildning. Det föreslås att ett kaotiskt beteende och skalförhållanden ar viktiga parametrar, och även om det kan tyckas i viss mån semantiskt, att det är avsiktligt och viktigt att använda termen drumlinoid för dessa komplexa former. Främsta skälet för det senare är begreppet ’equifinality`, d.v.s. tanken att flera olikartade processer kan leda fram till morfologiskt liknande slutresultat, till exempel att det vi kallar drumlinoider/drumliner har en processmässigt olikartad bakgrund (som bergdrumliner, bergkärnedrumliner eller erosivt bildade drumliner). Dock, även om denna typ av uppdelning är giltig med olika fysikaliska processer involverade i deras bildning så följer de slutliga landformerna ett glacialt form-kontinuum som på överordnad nivå måste betraktas som delar av samma familj.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/402a85a7-7827-43ed-85f6-36a88b2022de</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Kappa_low_res.pdf">https://portal.research.lu.se/files/3449019/8569676.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3994739</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Geology, Lund University</publisher> <dateIssued encoding="w3cdtf">2016</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>glacial flow</topic> <topic>drumlin</topic> <topic>self organising maps</topic> <topic>LiDAR</topic> </subject> <subject authority="lup"> <topic>Geology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lundqua thesis</title> </titleInfo> <identifier type="issn">0281-3033</identifier> <identifier type="issn">0281-3033</identifier> <identifier type="isbn">9789187847127</identifier> <identifier type="isbn">9789187847134</identifier> <identifier type="oldLupId">8569667</identifier> <identifier type="Scopus">85041701393</identifier> <part> <detail type="issue"> <number>80</number> </detail> <extent unit="pages"> <total>175</total> </extent> </part> </relatedItem> <relatedItem type="link"> <location> <url>https://www.scopus.com/pages/publications/85041701393</url> </location> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2016-02-19T13:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>402a85a7-7827-43ed-85f6-36a88b2022de</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-14T10:48:08Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:35+02:00</recordDateApproved> </recordInfo> </mods>

It is a common cause of otitis media in children, a usual infections agent in sinusitis and makes up to 10% of all exacerbations of chronic obstructive pulmonary disease (COPD). It is known to cause more frequent disease in the colder season, and, generally, its importance is recognised mainly in countries exposed to moderate climate. M. catarrhalis widely colonises infants and children but it is very uncommon for the bacterium to colonise the mucosa in adults.&lt;br/&gt;&lt;br&gt; The present thesis is concentrated on discussing two properties of M. catarrhalis, - binding and inactivation of alpha1-anticnymotrypsin (ACT) and complement component 3 (C3) for which M. catarrhalis outer membrane proteins “ubiquitous surface proteins” (Usp) A1/A2 are responsible. No other pathogenic bacterium is known to bind ACT. &lt;br/&gt;&lt;br&gt; The ACT is a serine protease inhibitor playing important part in antiprotease lung protection and anti-inflammatory signalling. We established that M. catarrhalis is able to bind and inactivate ACT through the two active domains on both UspA1 and A2 proteins. The phenomenon is proposed to be important for a) protease-antiprotease balance in the lung, for b) exacerbating inflammation and for c) inhibition of phagocytic clearance of M. catarrhalis. &lt;br/&gt;&lt;br&gt; The localization of ACT binding inside the UspA1 and A2 proteins provided us with means to develop a simple and quick method for purification of ACT from plasma or serum based on ACT affinity to a fragment of UspA2 protein of M. catarrhalis. The purification can be carried out practically in one step and the biological properties of ACT are retained. &lt;br/&gt;&lt;br&gt; In the last part of the thesis the C3 binding to M. catarrhalis Usp A1 and A2 was studied. The binding has been attributed to a single fragment in the both UspA1 and A2. Importantly, C3d fragment of C3 has been found responsible for the binding to UspA1/A2. The UspA2 has been demonstrated to inhibit both the classical and the alternative pathways of the complement. The C3 binding by M. catarrhalis strongly correlated with serum resistance of the bacterium, as well as with the expression of UspA1/A2.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/aa5d6fce-100c-4236-9dc1-379b30a75f26</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="kappanyManolov_g5.pdf">https://portal.research.lu.se/files/3449046/1275064.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">587141</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Laboratory Medicine, Lund University</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>cathepsin G</topic> <topic>inflammation</topic> <topic>serum resistance</topic> <topic>C3</topic> <topic>complement</topic> <topic>Moraxella catarrhalis</topic> <topic>antichymotrypsin</topic> <topic>affinity chromatography</topic> <topic>purification</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lunds University, Faculty of Medicine Doctoral Dissertation Series 2009</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-92-7</identifier> <identifier type="oldLupId">1275063</identifier> <part> <detail type="volume"> <number>2009:5</number> </detail> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-01-09T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>aa5d6fce-100c-4236-9dc1-379b30a75f26</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:35+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-27T10:03:40Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:35+02:00</recordDateApproved> </recordInfo> </mods>

ATP is degraded into adenosine by the enzyme apyrase, and adenosine possesses cardioprotective properties. ADC-1004 is an antagonist of the receptor to the activated complement factor C5a. Hypothermia has been shown to suppress the development of I/R injury. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In this thesis, the cardioprotective effects of ADC-1004 (paper I), apyrase (paper II) and hy- pothermia (paper III) were investigated. The effects of hypothermia on coronary t-PA release (paper IV), and on systemic t-PA release in cardiogenic shock (paper V) were also studied. An experimental porcine ischemia/reperfusion model was used. Infarct size (IS), microvascular obstruction and area at risk (AAR) were measured with ex-vivo MRI and SPECT.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; ADC-1004 treatment (paper I) was found to reduce infarct size (ADC-1004: 58.3±3.4 vs control: 74.1±2.9 %AAR, p=0.007) but not microvascular obstruction (ADC-1004: 2.2±1.2 vs control: 5.3±2.5 %AAR, p=NS). Treatment with apyrase (paper II) did not reduce infarct size (apyrase: 75.7±4.2 vs saline: 69.4±5.0 %AAR, p=NS) nor microvascular obstruction (apyrase: 10.7±4.8 vs saline: 11.4±4.8 %IS, p=NS). Hypothermia (paper III) reduced both infarct size (hypothermia: 60.8±4.9 vs normothermia: 73.8±4.0 %AAR, p&amp;lt;0.05) and microvascular obstruction (hypothermia: 0.5±0.5 vs normothermia: 21.5±5.2 %IS, p&amp;lt;0.001). Hypothermia also inhibited an increase in coronary net t-PA release during reperfusion (paper IV; hypothermia: 0.79±0.45 ng/ml vs normothermia: 9.44±4.34 ng/ml, p&amp;lt;0.05); and an increase in systemic net t-PA release in cardiogenic shock (paper V; hypothermia: 0.60 ± 0.12 ng/ml vs normothermia: 2.16 ± 1.09 ng/ml, p&amp;lt;0.05).&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; In conclusion, complement inhibition by ADC-1004 and therapeutic hypothermia reduces myocardial ischemia-reperfusion injury, and represents clinically applicable treatment strategies. Mechanistically, therapeutic hypothermia acts to reduce t-PA release in myocardial ischemia and cardiogenic shock. Treatment with apyrase does not protect the heart from ischemia/reperfusion injury.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/95e86895-bd85-4558-9b39-811c8ea29242</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Avhandling_Jesper_van_der_Pals.pdf">https://portal.research.lu.se/files/3449330/1785600.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">5802558</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Department of Cardiology, Clinical sciences, Lund University</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>ADC-1004</topic> <topic>apyrase</topic> <topic>Cardioprotection</topic> <topic>ischemia/reperfusion</topic> <topic>hypothermia</topic> <topic>t-PA</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-64-8</identifier> <identifier type="oldLupId">1785599</identifier> <part> <detail type="volume"> <number>2011:15</number> </detail> <extent unit="pages"> <total>78</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-03-04T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>95e86895-bd85-4558-9b39-811c8ea29242</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:39+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:39+02:00</recordDateApproved> </recordInfo> </mods>

The unemployment rate increased significantly and the proportion of young adults receiving social assistance rose dra-matically. In response, municipalities initiated local intervention programs aimed at reducing the number of young social assistance recipients. In 2005, this population had decreased. However, the organization of local interventions targeting young unemployed recipients of social assistance remained intensified in the munici-palities. The aim of this study is to analyze social mechanisms that explain the increased importance of local intervention programs for young unemployed people.&lt;br/&gt;&lt;br&gt; The results of the thesis show how local intervention programs are justified by images of young unemployed people receiving so-cial assistance and their life situations, i.e their lack of education, their deviating norms and behavior, their personal social problems and the corruptive effects of social assistance. Three categorical pairs influenced the organization of (such) programs: a) clients over and under the age of 25 b) clients deemed deserving and un-deserving c) clients considered able and those considered unable to work. These categorizations have determined which types of inter-ventions have been organized. By organizing programs the munici-pal organizations have gained valuable resources aiding their ad-vancement and influence, such as financial funding, suitable clients and legitimacy. &lt;br/&gt;&lt;br&gt; The development of local intervention programs for young un-employed recipients of social assistance can be understood as a process of institutionalization; a certain way of organizing is unal-tered, remaining regardless the devolution of the initially perceived problem.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/00065e18-8022-40fc-adc9-0fb653c66dfe</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Problemen_forgar__losningarna_bestar.pdf">https://portal.research.lu.se/files/3449510/1728739.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">2014858</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lunds universitet, Socialhögskolan</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>social assistance</topic> <topic>unemployed</topic> <topic>young adults</topic> <topic>municipalities</topic> <topic>Human service organizations</topic> <topic>legitimacy</topic> <topic>local intervention pro-grams</topic> </subject> <subject authority="lup"> <topic>Social Work</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund Dissertation in Social Work</title> </titleInfo> <identifier type="issn">1650-3872</identifier> <identifier type="isbn">978-91-89604-48-3</identifier> <identifier type="oldLupId">1728625</identifier> <part> <detail type="volume"> <number>41</number> </detail> <extent unit="pages"> <total>252</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2010-12-17T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>00065e18-8022-40fc-adc9-0fb653c66dfe</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:40+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:40+02:00</recordDateApproved> </recordInfo> </mods>

The purpose is&lt;br/&gt;&lt;br&gt; to show the conditions given by the novels which could promote children’s own historical consciousness and&lt;br/&gt;&lt;br&gt; how the characters are portrayed in order for the readers to be able to identify with them. Two functions of&lt;br/&gt;&lt;br&gt; the novels are studied: &amp;lt;i&amp;gt;knowledge&amp;lt;/i&amp;gt; and &amp;lt;i&amp;gt;analogy&amp;lt;/i&amp;gt;. Within the analysis of analogy the concept of empowerment is&lt;br/&gt;&lt;br&gt; central to the portrayal of the protagonist.&lt;br/&gt;&lt;br&gt; &amp;lt;br&amp;gt;&lt;br/&gt;&lt;br&gt; The textual analysis shows that the protagonist’s situation as a migrant above all points to cultural encounters&lt;br/&gt;&lt;br&gt; both in the past and in the present time and further highlights the situation of the slaves in the Viking age.&lt;br/&gt;&lt;br&gt; The apparent analogy of the present time means that the novels are well suited to discussions about ethics, the&lt;br/&gt;&lt;br&gt; value of human beings and cultural encounters.&lt;br/&gt;&lt;br&gt; &amp;lt;br&amp;gt;&lt;br/&gt;&lt;br&gt; In the second part of the thesis I analyse 11-year-old children’s reading of Bylock’s trilogy. Three pupils’&lt;br/&gt;&lt;br&gt; texts, book talks and interviews and experiences of the novels have been documented during a six week long&lt;br/&gt;&lt;br&gt; thematic project on the Viking age. The analysis is conducted amongst others with the help of Judith A. Langer’s&lt;br/&gt;&lt;br&gt; concept envisionment building. The pupils’ historical consciousness development and newfound knowledge&lt;br/&gt;&lt;br&gt; can partly be related to the analogy and the themes found in the novels. With the assistance of the novels’&lt;br/&gt;&lt;br&gt; “living characters”, the exciting plot and an emotional envolvement the pupils have acquired knowledge and&lt;br/&gt;&lt;br&gt; at the same time developed their historical consciousness. Book talks are of crucial importance in this.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9ae0afd2-cce3-4b0b-b3b8-7a359fbea498</url> </location> </relatedItem> <originInfo> <publisher>Makadam förlag</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>Judith A.

This new politics concerns transformative social change aimed at moving society away from its current dependence on fossil carbon energy. A transition to low-carbon societal development hinges on restructuring and decarbonising those key systems, structures and practices that generate carbon emissions. Engaging with theoretical perspectives on the state in environmental governance and its role in steering policy change and enabling system transformations, I examine how the state can govern decarbonisation through exploring empirical examples across a wide range of policy sectors such as energy, transport and industry. Given the centrality of state authority in the organisation of modern society, a low carbon transition is conditioned on authoritative steering, long-term active support of state institutions and a diversified portfolio of policy approaches and objectives.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; The material for this compilation thesis is drawn from the Swedish policy realm. The included papers analyse the development of arrangements for environmental governance, climate policy discourse and institutional conditions for governing low-carbon transitions by means of public policy in Sweden. A key insight across these papers is that the state remains a critical site for steering and enabling system transformations. A modern (environmental) welfare state, such as Sweden, holds untapped capacities to govern decarbonisation by progressively advancing and scaling up the efforts to reorient societal development. Thus, a decarbonising state can be made more actively engaged in steering and enabling processes of low-carbon transitions, and could explore new ways for orchestrating a wide range of low-carbon initiatives and developments.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in English&lt;/b&gt;&lt;br/&gt;&lt;br&gt; The new climate politics of decarbonisation address the prospects for moving society away from its current dependence on fossil carbon energy.

Based on insights from the development of climate governance arrangements and institutional conditions for public policy in Sweden, Hildingsson proposes that the modern (environmental) state holds untapped capacities to govern decarbonisation. These capacities can be progressively explored to advance and scale up the efforts to reorient societal development.

Previous studies have pointed out inflammation, driven&lt;br/&gt;&lt;br&gt; by inflammatory lipids, as the keystone in the formation of the rupture prone vulnerable plaque. The risk for a&lt;br/&gt;&lt;br&gt; plaque rupture is greatly enhanced in the diabetic population and increased inflammation has been suggested as the&lt;br/&gt;&lt;br&gt; contributing factor. However, the mechanism remains unknown. One of the current greatest challenges in the&lt;br/&gt;&lt;br&gt; atherosclerotic field is to identify subjects with plaques that are vulnerable before the occurrence of a plaque&lt;br/&gt;&lt;br&gt; rupture.&lt;br/&gt;&lt;br&gt; In this thesis we provide evidence that the enzyme lipoprotein associated phospholipase A2 (LpPLA2) and the&lt;br/&gt;&lt;br&gt; lipids lysophosphatidylcholines and sphingolipids (ceramides, lactosylceramides, glucosylceramides) contribute to&lt;br/&gt;&lt;br&gt; the inflammatory process and that they are associated with the vulnerable plaque. This suggests that the synthesis&lt;br/&gt;&lt;br&gt; of these lipids may be possible therapeutic targets. We also show that the inflammatory process in the plaque is&lt;br/&gt;&lt;br&gt; reflected in the peripheral blood, as measured by cytokines, whereas no association was found for soluble&lt;br/&gt;&lt;br&gt; urokinase-type plasminogen activator receptor. The inflammatory cytokines MIP-1β, TNF-α and fractalkine&lt;br/&gt;&lt;br&gt; predict the inflammatory plaque with high sensitivity and specificity, proposing that these inflammatory cytokines&lt;br/&gt;&lt;br&gt; could be used as plasma markers for plaque inflammation. Finally, we provide novel data regarding the biology of&lt;br/&gt;&lt;br&gt; the diabetic plaque. According to our data the inflammatory activity is not increased in the diabetic plaque tissue.&lt;br/&gt;&lt;br&gt; Diabetic plaques contained less stabilizing extracellular matrix proteins (collagen and elastin). Additionally the&lt;br/&gt;&lt;br&gt; plaque levels of the inflammation regulating cytokine IL-10 and the growth factor platelet derived growth factor&lt;br/&gt;&lt;br&gt; as well as the smooth muscle cell stimulating matrix metalloproteinase 2 were significantly decreased in diabetic&lt;br/&gt;&lt;br&gt; plaque tissue. These findings were independent of the presence of symptoms.&lt;br/&gt;&lt;br&gt; In summary, this thesis shows that lipids as LysoPCs and glycosphingolipids are important inducers of plaque&lt;br/&gt;&lt;br&gt; inflammation and may be possible therapeutic targets. In the general population the inflammatory activity is an&lt;br/&gt;&lt;br&gt; important factor for the formation of a vulnerable plaque and this inflammatory process is reflected in blood,&lt;br/&gt;&lt;br&gt; hinting a role for fractalkine, MIP-1β and TNF-α as future biomarkers. In the diabetic population, however, an&lt;br/&gt;&lt;br&gt; impaired tissue repair mechanism seems to be the keystone of plaque vulnerability, rather than inflammation,&lt;br/&gt;&lt;br&gt; emphasizing the need for new therapeutic approaches for diabetics.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Åderförkalkning, den i folkmun använda benämningen för ateroskleros, är en sjukdom som de flesta lider av. Vi vet bara inte om det. Ateroskleros ger nämligen sällan symptom innan ett aterosklerotiskt plack (en lokal aterosklerosansamling i kärlväggen) brister och det bildas en blodpropp. Om placket som brister sitter i kärlen som förser hjärtat eller hjärnan med blod kan man drabbas av en hjärtinfarkt eller stroke. Två av de vanligaste dödsorsakerna i världen. Under de senaste decennierna har vi lärt oss mycket om hur sjukdomen initieras och vad som bidrar till dess vidare progress. Ökad kunskap och nya behandlingsmetoder för akut hjärtinfarkt och stroke har gjort att mortaliteten i den akuta fasen minskat.&lt;br/&gt;&lt;br&gt; Dessvärre ökar morbiditeten. Många som drabbats lider av och dör slutligen av komplikationer såsom hjärtsvikt och arytmier. För att vi ska lyckas minska morbiditeten måste vi identifiera de individer som har hög risk att drabbas av hjärt-kärlsjukdom. Om vi kan finna dessa individer i tid kan vi istället påbörja en intensiv preventiv behandling och förebygga plackrupturen innan de drabbas av hjärtinfarkt eller stroke. Trots att vi idag vet hur vi genom livsstilsförändring kan minska risken för insjuknande i hjärt-kärlsjukdom finns det fortfarande faktorer som inte går att eliminera. En av dessa faktorer är diabetes typ 1 men även till viss del diabetes typ 2. Diabetes är en av de viktigaste riskfaktorerna för att insjukna i kardiovaskulär sjukdom och trots intensiv forskning vet vi än idag inte varför. Gällande hypotes idag är att åderförkalkning utvecklas till följd av att cirkulerande blodlipider, främst låg densitet lipoproteiner (LDL, det onda kolesterolet), fastnar i kärlväggen och med tiden startar en inflammatorisk reaktion. Den inflammatoriska processen bryter ner stabiliserande komponenter i kärlväggen vilket leder till försvagning av kärlväggen som slutligen brister. När detta sker kommer blodet som strömmar genom kärlet i kontakt med det underliggande placket och det bildas en propp av koagulerat blod. Och en akut kärlkomplikation är ett faktum.&lt;br/&gt;&lt;br&gt; I denna avhandling har vi studerat blod och humana aterosklerotiska plack från artärerna i halspulsådern (arteria carotis). Fokus har riktats mot inflammationens betydelse i utvecklingen av vulnerabla plack (plack som tenderar att brista). Därutöver har vi undersökt hur olika lipider påverkar den inflammatoriska processen i kärlväggen och slutligen hur plackbiologin skiljer mellan diabetiker och icke-diabetiker. För att upptäcka nya sätt att detektera individer med hög risk för plackruptur har vi undersökt samband mellan uttrycket i blod och i plackvävnad för olika inflammatoriska markörer och lipider.&lt;br/&gt;&lt;br&gt; LDL som fastnat i kärlväggen förändras med tiden och blir oxiderat LDL. Då LDL oxiderats kan delar av LDL molekylen brytas ned av ett enzym som kallas lipoprotein associerat fosfolipas A2 (Lp-PLA2). När detta sker bildas en ny typ av lipider, lysofosfatidylkoliner (LysoPCs) som ter sig kunna inducera en kraftig inflammatorisk reaktion. LysoPCs och Lp-PLA2 finns i humana aterosklerotiska plack och framförallt i plack som brustit. Det finns idag ett läkemedel som hämmar Lp-PLA2, men man vet ännu inte hur LpPLA2 bidrar till plackets vulnerabilitet i människor och hur detta läkemedel påverkar inflammationen i kärlväggen. I denna avhandling visar vi att Lp-PLA2 är starkt associerat till inflammation i human plackvävnad och att LysoPCs bidrar till den inflammatoriska reaktionen. Genom att tillsätta en inhibitor av Lp-PLA2 hämmas det inflammatoriska svaret vilket stärker Lp-PLA2s roll som ett potentiellt mål vid behandling av hjärt-kärlsjukdom.&lt;br/&gt;&lt;br&gt; Oxiderat LDL påverkar även syntesen av flera andra lipider, däribland ceramider och glykosfingolipider (glucosylceramide och lactosylceramide). Det har länge varit känt att glykosfingolipider finns ansamlade i human plackvävnad. Deras roll i den aterosklerotiska utvecklingen har dock varit okänd. Nyligen publicerades en studie som visade att man kunde hämma utvecklingen av aterosklerotiska plack hos möss genom att inhibera syntesen av glykosfingolipider och därigenom även minska inflammationen. Våra resultat visar att ceramider och glykosfingolipider är högre i plack som har brustit och är kopplade till den inflammatoriska processen.&lt;br/&gt;&lt;br&gt; Genom att stimulera muskelceller från kärlväggen med dessa lipider lyckades vi inducera ett inflammatoriskt svar och framkalla celldöd. Minskande antal muskelceller i placket och ökad inflammation anses som två viktiga komponenter för att placket skall brista vilket talar för glykosfingolipider och ceramider bidrar till en ökad risk för plackruptur.&lt;br/&gt;&lt;br&gt; Plack hos diabetiker har tidigare visats vara kraftigt inflammerade i förhållande till plack från icke-diabetiker, men genesen är oklar. Den ökade inflammatoriska aktiviteten har antagits vara orsaken till att placken hos diabetiker rupturerar i en högre utsträckning än hos icke-diabetiker. För att undersöka olika anledningar till plackruptur hos diabetiker jämförde vi plack från diabetiker med plack från ickediabetiker. Enligt våra resultat var placken från diabetiker inte mer inflammerade. Däremot innehöll de betydligt mindre av de stabiliserande bindvävsproteinen kollagen och elastin. Plack från diabetiker innehöll även lägre nivåer av tillväxtfaktorer och enzym som inducerar kollagensyntes. Våra resultat är av stor betydelse eftersom vi påvisar att andra faktorer än just inflammationen i kärlväggen kan vara av betydande för utvecklandet av vulnerabla plack hos diabetiker.&lt;br/&gt;&lt;br&gt; För att se om den lokala inflammationen kunde avspeglas i det cirkulerande blodet valde vi att titta på Lp-PLA2, löslig urokinas-typ plasminogen aktivator receptor (suPAR) och inflammatoriska cytokiner. Alla har föreslagits som möjliga&lt;br/&gt;&lt;br&gt; markörer för hjärt-kärlsjukdom. Det har dock varit okänt hur dessa markörer förhåller sig mellan blodet och plackvävnaden. Lp-PLA2 har i flera studier visat sig vara en bra markör för framtida hjärt-kärlsjukdom. I vår studie fann vi, att nivåer i blodet korrelerade mot nivåerna i placken, vilket talar för att Lp-PLA2 även kan vara en lämplig markör för vulnerabla plack. suPAR är en rest efter att den membranbundna receptorn urokinas plasminogen aktivator receptor (uPAR) brutits ned. suPAR stiger vid många inflammatoriska tillstånd i blodet och uPAR förekommer i human plackvävnad med mycket inflammatoriska celler. Den lösliga formen, suPAR, har visat sig vara en markör i blodet för framtida hjärtkärlsjukdom. Vår studie visade att patienter som drabbats av stroke hade förhöjda nivåer av suPAR i blodet och i plackvävnad. Däremot förelåg ingen association mellan plack och blodnivåer vilket talar för att suPAR i blodet möjligen inte återspeglar uPAR-klyvning som sker i placket. Blodnivåer av suPAR var dock förhöjda hos diabetiker och kan vara en markör för individer som har hög risk att utveckla hjärt-kärlsjukdom.&lt;br/&gt;&lt;br&gt; Cytokiner är cellers signaleringsmolekyler. Ett flertal cytokiner frisätts från olika celler i vävnad vid inflammation. Att dessa inflammatoriska cytokiner kan mätas i plasma är känt sedan länge och flertalet har visat sig stiga hos patienter med hjärtkärlsjukdom. Det har dock inte varit känt hur dessa cytokiner i plasma återspeglar inflammationen i kärlväggen. Vår studie påvisar samband mellan flertalet cytokiner i plack och i blod. Nivåerna av vissa cytokiner var också betydligt högre i plackvävnad än i blod vilket talar för att det sker ett visst utträde från placket till blodet. Enligt våra resultat var fraktalkine, tumörnekrosfaktor-α (TNF-α) och makrofag inflammatoriskt protein-1β (MIP-1β) de cytokiner som med störst sensitivitet och specificitet kunde prediktera den inflammatoriska graden i kärlväggen.&lt;br/&gt;&lt;br&gt; Sammantaget visar vi i denna avhandling att inflammation är en viktig bidragande faktor till plackruptur hos personer utan diabetes och att lipider, LysoPCs och glykosfingolipider, verkar initiera denna process. Att hämma syntesen av dessa lipider kan vara ett effektivt sätt att minska kärlväggsinflammationen. Hos diabetiker verkar dock inte inflammationen spela så stor roll som man tidigare trott utan snarare verkar diabetiker ha en förhöjd risk för plackruptur på grund av en försämrad läkningsförmåga i kärlväggen. Att en försämrad sårläkning kan vara en av de viktiga faktorerna för plackruptur hos diabetiker är en viktig kunskap som kan spela stor roll i utvecklandet av nya läkemedel för diabetiker. Slutligen har vi påvisat starka markörer blodet som återspeglar kärlväggsinflammationen. Förutom Lp-PLA2 fann vi även att de inflammatoriska cytokinerna MIP-1β, TNF-α och fraktalkine var associerade till inflammationen i placket. Innebörden av detta fynd är att vi kan förstå hur ämnen passerar ut ur placket till blodcirkulationen eller från blodcirkulationen till placket. Med ökad kunskap om hur molekyler rör sig över kärlväggen ökar vi inte bara chansen att finna en bra markör i blodet utan även möjligheten att kombinera en biomarkör med en bildmetod för att kunna lokalisera placket.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/9e158c42-7656-4b23-a7e8-cf432383a862</url> </location> </relatedItem> <originInfo> <publisher>Experimental Cardiovascular Research Unit, Lund University</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Atherosclerosis</topic> <topic>Carotid plaque</topic> <topic>Inflammation</topic> <topic>Diabetes</topic> <topic>LpPLA2</topic> <topic>suPAR</topic> <topic>Cytokines</topic> <topic>Lipids</topic> </subject> <subject authority="lup"> <topic>Cardiology and Cardiovascular Disease</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87449-89-5</identifier> <identifier type="oldLupId">4124101</identifier> <part> <detail type="volume"> <number>2013:116</number> </detail> <extent unit="pages"> <total>117</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-11-15T13:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>9e158c42-7656-4b23-a7e8-cf432383a862</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:51+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:51+02:00</recordDateApproved> </recordInfo> </mods>

Instrumentet har fått namnet Time in Care (TiC) och är uppdelat i två delar: Time in Care for need (TiC-n), som mäter det individuella omvårdnadsbehovet, och Time in Care for time (TiC-t), som mäter tiden det tar att utföra de vårdaktiviteter vilka är relaterade till vårdtagarnas omvårdnadsbehov. Denna utveckling beskrivs i studie 1 och 2. I studie 3 var syftet att bedöma aktuellt vårdbehov (TiC-n) hos vårdtagare inom särskilt boende och den tidsåtgång (TiC-t) som krävdes för att med 32 omvårdnadsaktiviteter möta dessa vårdbehov, d.v.s. att mäta nursing intensity och slutligen var syftet i studie 4 att jämföra två metoder för resursfördelning av personal. Den första är en svensk metod (Care Optimizer) och den andra en i England etablerad metod (Acuity-Quality). Jämförelsen baseras på samma empiriska data. Syftet var även att analysera metodernas styrkor och svagheter relaterat till utfallet. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Studie 1 genomfördes på 13 särskilda boenden med sammanlagt 505 vårdtagare. Metodutvecklingen av TiC genomfördes med ett flertal analysmetoder. I studie 1 beräknades styrkan för respektive item med en faktoranalys (principal component) för att om möjligt reducera antalet items. Interbedömarreliabiliteten undersöktes med viktad kappa (kw). Homogeniteten för TiC-n undersöktes med Cronbach’s alpha. I studie 2 som innefattade underlag från två kommuner med liknande struktur bedömdes vårdbehovet på1282 vårdtagare. Beräkning genomfördes med samma analysmetoder som i studie 1. I studie 2 faställdes även brytpunkten i skalan på respektive vårdnivå med hjälp av regressionsanalys och scatterdiagram. I studie 3 utfördes tidsmätningarna med hjälp av en scannersticka med de 32 aktiviteterna inprogrammerade. Bearbetning skedde i ett skräddarsytt dataprogram. Intra-klass korrelationskoefficienten (ICC) beräknades av tidsåtgång för de 32 vårdaktiviteterna (totalt antal 10 546) i relation till vårdbehoven i de fem vårdnivåerna och de två undersökningsveckorna. Kruskal - Wallis test användes för att synliggöra hur skillnaderna i tiden fördelade sig mellan vårdnivåerna. Studie 4 innebar en progress av studie 2 och 3 med syfte att jämföra två metoder för att beräkna andelen personalresurser som krävdes för att möta vårdtagares vårdbehov. Care Optimizer metoden jämfördes med Acuity-Quality metoden . Metoderna har valts med utgångspunkt från att de båda inkluderar bedömning av vårdbehov. Samma empiriska data har lagts in i båda metodernas underlag för att få en så jämförbar utgångspunkt som möjligt. Båda metodernas slutresultat redovisas i Whole Time Equivalents (WTE’s) och kan därför jämföras. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Faktoranalysen i studie 1 resulterade i att fyra faktorer kunde reduceras till tre faktorer: Allmän omvårdnad (11 items), Medicinsk omvårdnad (1 items) och Kognitiv omvårdnad (7 items). Vid förnyad analys i studie 2 kunde de tre faktorernas resultat från studie 1 fastställas. Korrelationen mellan de tre faktorerna var vid analys med Spermans Rho signifikanta. För hela TiC-n var Cronbach’s alpha 0.85. Totalt förklarades 66,6 % av variansen. För att säkra interbedömarreliabiliteten gjordes en viktad kappa analys på hela materialet från båda kommunerna. Resultatet för respektive kommun visade ett kappa värde för kommun 1 (n=453) på 0.76 (spridning 0.50 – 0.97) och för kommun 2 (n=829) på 0,75 (spridning 0.60 – 0.87). Totalt för de båda kommunerna (n=1282) var kappavärdet 0.75. Regressionsanalys mellan behovspoäng och vårdnivå visade på ett justerat R2 för den första versionen av TiC-n med 16 items på 0.98 och för den andra versionen med 19 items på 0.95. I studie 3 var det sammanlagda medeltalet för de båda särskilda boendenas samtliga 14 aktiviteter i Direkt omvårdnadstid 6 minuter/vårdtagare och dag (spridning 1-73 minuter). I Indirekt omvårdnadstid var det 5 minuter/vårdtagare och dag (spridning 1-123 minuter) och i Arbetsplatsrelaterad omvårdnadstid var medeltalet 9 minuter (spridning 1-148 minuter). Intra-klass korrelationskoeffiecienten (ICC) beräknades till 0.854 (F test, p = .0001). Kruskal -Wallis test visade att tidsåtgången varierade som mest mellan vårdnivå fyra och fem. Resultatet i studie 4 visar att vid jämförelse mellan de båda metodernas resultat framkom en skillnad avseende hur många årsarbetare (WTE’s) relaterat till aktuellt vårdbehov som åtgick för att tillgodose aktuellt vårdbehov för respektive särskilt boende. I Care Optimizer metoden synliggjordes en skillnad avseende bemanning på respektive demensavdelning, vilket gör att medeltalet i vårdpoäng blir lägre för särskilt boende 1 då detta boende endast hade en avdelning för demensvård. Denna skillnad framkommer inte vid beräkning med Acuity- Quality metoden. Av resultatet framkom att vid jämförelse av de båda metoderna var Care Optimizer metoden mer känslig för hur de individuella vårdbehoven påverkade aktuell bemanning. Ett högre vårdpoäng i medeltal innebar att mer resurser krävdes. Care Optimizer metoden var dessutom inte beroende av att en tidsstudie gjordes för att fastställa tidsåtgången i respektive vårdnivå. De resurser som krävdes för att tillgodose aktuellt vårdbehov kunde vid beräkning i Care Optimizer metoden synliggöras direkt vid vårdbehovsbedömning med TiC-n.&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Care Optimizer metoden behöver fortsatt forskning för att replikera de här erhållna resultaten och för att kunna genomföra eventuella modifieringar av såväl TiC-n som TiC-t. Studier behöver genomföras med ett större antal kommuner som också representerar storstad och landsbygd. Care Optimizer behöver kompletteras med en dimension som mäter personalens kompetens. Här återstår ett utvecklingsarbete för att formulera de viktigaste indikatorerna på vad som ska innefattas i kompetensbegreppet. Kriterier för en certifiering av att använda Care Optimizer metoder vore också önskvärd. &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Konstateras kan att Care Optimizer är en potentiellt användbar metod för att utifrån individuellt bedömda vårdbehov bemanna kommunala särskilda boenden. Reliabilitet och validitet för TiC-n och TiC-t har i ett första skede fått stöd med gjorda analyser. Care Optimizer har en god känslighet för att möta förändringar i vårdbehov och vårdnivåer. Care Optimizer metoden är enkel att använda i jämförelse med andra metoder bemanning och slutligen Care Optimizer är kombinerad med en komplett mjukvara.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/8c035e5c-9968-4e8f-b394-04c32bec5fc8</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="thorsell_kappa.pdf">https://portal.research.lu.se/files/3450604/1749874.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">630560</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Lund University, Faculty of Medicine</publisher> <dateIssued encoding="w3cdtf">2010</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>särskilda boenden</topic> <topic>nursing intensity</topic> <topic>vårdtyngd</topic> <topic>vårdbehov</topic> <topic>tidsstudier</topic> <topic>Klassificeringsinstrument</topic> <topic>resursfördelning</topic> <topic>äldreomsorg.</topic> </subject> <subject authority="lup"> <topic>Nursing</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86671-54-9</identifier> <identifier type="oldLupId">1749871</identifier> <part> <detail type="volume"> <number>2011:6</number> </detail> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-01-21T09:00:00+01:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

Encapsulated H. influenzae strains exist in six different serotypes a-f, of which type b (Hib) is the most virulent. Hib is protected by the polysaccharide capsule when invading the blood circulaton and may cause diseases such as meningitis and epiglottitis. Non-encapsulated H. influenzae referred to as nontypeable H. influenzae (NTHi), are frequently associated with acute otitis media in children and chronic obstructive pulmonary disease (COPD) among the elderly. H. influenzae expresses several outer membrane proteins of which the adhesins play an important role in the initial interactions with the airway epithelium. &lt;br/&gt;&lt;br&gt; In this thesis, we have studied two Haemophilus influenzae adhesins and their interactions with innate defense mechanisms. Vitronectin is a glycoprotein that regulates the terminal pathway of the complement system by inhibiting the membrane attack complex. We demonstrate that Haemophilus influenzae surface fibrils (Hsf) may increase the bacterial survival by interacting with vitronectin in serum. &lt;br/&gt;&lt;br&gt; We also describe the isolation and characterization of a novel H. influenzae adhesin designated protein E (PE). PE was isolated by using an IgD myeloma serum which specifically recognized the protein on the bacterial surface. Furthermore, PE was found to be a 16 kDa protein and classified as a lipoprotein. PE displays adhesive activity to three respiratory epithelial cell lines and erythrocytes, both when expressed on the surface of H. influenzae and as a recombinant protein in E. coli. The active adhesive binding domain has been determined to be located within the central part of the molecule, PE amino acids 84-108. PE shows stimulatory effects when incubated with respiratory epithelial cells by inducing high levels of IL-8 and ICAM-1. These inflammatory mediators play an important role for the innate immune response and the recruitment of neutrophils. Finally, PE promotes bacterial invasion into epithelial cells. &lt;br/&gt;&lt;br&gt; In summary, the work presented in this thesis shows that Hsf may prolong the bacterial survival by interacting with the complement regulator vitronectin. The novel protein PE has been isolated, characterized and shown to be important for interactions of H. influenzae with the innate immune system.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/37ad9057-a5f2-4dfc-a17b-18837a6caa21</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="ramintroduction.doc.pdf">https://portal.research.lu.se/files/3450690/946503.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">605900</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Medical Microbiology, Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>inflammation</topic> <topic>Haemophilus influenzae</topic> <topic>Haemophilus surface fibrils</topic> <topic>complement</topic> <topic>innate immune response</topic> <topic>protein E</topic> <topic>respiratory epithelium</topic> <topic>adhesins</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-85897-57-5</identifier> <identifier type="oldLupId">838535</identifier> <part> <detail type="volume"> <number>2008:6</number> </detail> <extent unit="pages"> <total>62</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-01-08T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>37ad9057-a5f2-4dfc-a17b-18837a6caa21</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:53+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-27T10:03:52Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:53+02:00</recordDateApproved> </recordInfo> </mods>

Purpose number one entails describing and analysing the legal opportunities for, and the demands on, the work of the actors in question with regard to children as victims of crime. This purpose intends to illustrate the legal regulation, which in different ways, and to different degrees, controls the work of the actors. Whereas the legislation provides a certain type of action on the part of the actors, and to different extents entails a normative framework for the actors work, it does not constitute an exact direction in terms of the actions of the actors. Determining existing law is not equivalent to determining the actions of the actors. The second purpose of the thesis relates to the relationship between the legal regulation and the actions of the actors, that is, whether or not the actors can be said to having fulfilled the legal requirements when carrying out their work with children as victims of crime. This section involves a comparison of the correspondence between legal regulations and actions. To create an understanding and explanation to the first and second purposes, purpose number three entails the investigation of what factors influence the actions of the actors when carrying out their work with children as victims of crime. To investigate what factors influence the actors when carrying out their work with children as victims of crime, the three concepts: will, knowledge and system, will be used. The methods of interview, questionnaire and analysis of literature have been combined for the different purposes.With regard to purpose number one of the thesis, the investigation shows that, two different processes can be initiated. These processes concern the same child, but the actors that are present in the different processes have different responsibilities with regard to the child. In some instances the legislation stipulates clear directions for the actors to follow, whereas in other instances the legislation stipulates an objective or a result that is desirable while the specific action is not stipulated. When it comes to the second purpose of the thesis, the study has, among other things, shown that the current legislation, which in different ways regulates specific actions, is not always observed by the actors. With regard to the final purpose of the thesis the investigation shows that the different factors influence the actors’ work with children as victims of crime to different extents and in different ways. This consequently means that neither of the different influencing factors irrevocably can be said to be more important than the others. Instead, the study has demonstrated the interdependence that exists between the different influencing factors, which in the actors’ day-to-day work interact and influence one another.</abstract> <abstract lang="swe">&lt;b&gt;Popular Abstract in Swedish&lt;/b&gt;&lt;br/&gt;&lt;br&gt; Att arbete med barn som brottsoffer – en rättssociologisk studie&lt;br/&gt;&lt;br&gt; Barn som utsätt&apos;s för brott utgör en grupp i vårt samhälle som i många situationer är beroende av företrädare för att få den hjälp och behandlig som de kan vara i behov av. I många fall är barnet&apos;s vårdnadshavare företrädare, men i vissa fall kan det vara vårdnadshavarna som utgör ett hot för barnet. I dessa fall är det samhället, i form av socialtjänsten, som har ansvar för att barnet inte far illa. När polisen tar emot en anmälan där målsägande är ett barn, sätt&apos;s en proces&apos;s igång som syftar till att utreda huruvida ett brott är begånget eller inte. Vid misstanke om att socialtjänsten kan behöva ingripa till ett barn&apos;s skydd har polisen även en ovillkorlig skyldighet att anmäla detta till socialtjänsten. I och med socialtjänsten&apos;s medverkan sätt&apos;s en annan proces&apos;s igång, som syftar till att utreda om barnet kan vara i behov av stöd, skydd och hjälp från socialtjänsten. Avhandlingen handlar om det arbete som nämnda aktörer utför för dessa barn. Aktörerna&apos;s agerande kan ha stor betydelse för det enskilda barnet&apos;s återhämtningsproces&apos;s, och även för barnet&apos;s fortsatta förtroende för aktörerna som det möter i och med att en anmälan till polisen initiera&apos;s . Detta understryker vikten av aktörerna&apos;s agerande vid utförandet av sina arbetsuppgifter . &lt;br/&gt;&lt;br&gt; Avhandlingen består av tre olika syften. Syfte nummer ett är att beskriva och analysera de rättsliga förutsättningarna för, och kraven på, de aktuella aktörerna&apos;s arbete rörande barn som brottsoffer. Detta syfte avser att ge en bild av den rättsliga reglering som på olika sätt och i olika grad styr aktörerna&apos;s arbete. Emedan lagstiftningen föreskriver ett visst agerande från aktörerna&apos;s sida, och i olika utsträckning utgör en normativ ram för aktörerna&apos;s arbete, utgör den inte en exakt anvisning för aktörerna&apos;s agerande. Att fastställa gällande lag är inte detsamma som att fastställa aktörerna&apos;s agerande. Avhandlingen&apos;s syfte nummer två berör förhållandet mellan den rättsliga regleringen och aktörerna&apos;s agerande, det vill säga huruvida aktörerna kan säga&apos;s uppfylla de rättsligt ställda kraven i arbetet med barn som brottsoffer. Denna del innebär en jämförelse av överensstämmelsen mellan rättsliga regleringar och agerande. &lt;br/&gt;&lt;br&gt; Medan syfte nummer ett beskriver existerande lagstiftning, och därmed en normativ utgångspunkt för aktörerna&apos;s agerande, ger syfte nummer två en bild av huruvida aktörerna kan säga&apos;s uppfylla denna reglering. Förhållandet mellan lagen, det vill säga det normativa ”bör” och aktörerna&apos;s agerande, det vill säga ”är” blir här centralt. Fram till denna del kan undersökningen säga&apos;s utgöra en klassisk rättssociologisk studie där förhållandet mellan lag och lagen&apos;s efterlevnad undersök&apos;s. För att skapa en förståelse och förklaring till syfte nummer ett och två, innebär syfte nummer tre att undersöka vilka faktorer som är med och påverkar aktörerna&apos;s agerande i arbetet med barn som brottsoffer. Här utgör lagstiftning bara en av flera möjliga påverkansfaktorer. För att undersöka vilka faktorer som påverkar aktörerna i arbetet rörande barn som brottsoffer, kommer de tre begreppen vilja, kunskap och system att använda&apos;s . Dessa begrepp kommer att utgöra del&apos;s ett metodologiskt arbetsredskap, del&apos;s en utgångspunkt för avhandlingen&apos;s analy&apos;s . Användandet av begreppen som metodologiskt arbetsredskap innebär att de utgör en mall för vilka påverkansfaktorer som undersök&apos;s, samt att det empiriska materialet sorterat&apos;s utifrån dessa begrepp . Användandet av begreppen som utgångspunkt för analy&apos;s innebär att även förståelsen av aktörerna&apos;s agerande utgår från dessa begrepp. Analysen av vilka påverkansfaktorer som aktörerna så att säga möter i sitt arbete med barn som brottsoffer utgår sålede&apos;s från dessa begrepp. För att skapa en förståelse för aktörerna&apos;s agerande använd&apos;s även begreppet handlingsutrymme, ett begrepp som beskriver inom vilka ramar aktörerna har att utföra sitt arbete. &lt;br/&gt;&lt;br&gt; För de olika syftena har metoderna intervju, enkät samt dokumentstudier kombinerat&apos;s.&lt;br/&gt;&lt;br&gt; När det gäller avhandlingen&apos;s syfte nummer ett, en beskrivning och analysering av de rättsliga förutsättningarna för aktörerna&apos;s arbete med barn som brottsoffer, visar undersökningen att i och med att en anmälan inkommer till polisen där brottsoffret är ett barn kan två olika processer initiera&apos;s. Dessa processer rör sig om samma barn, men aktörerna&apos;s som befinner sig i de olika processerna har olika ansvar i förhållande till barnet. Detta kan åskådliggöra&apos;s med följande bild:&lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; &lt;br/&gt;&lt;br&gt; Den normativa ramen som lagen utgör pekar på vilket agerande som är önskvärt från aktörerna&apos;s sida. I vissa fall anger lagstiftningen tydliga anvisningar som aktörerna kan följa, i andra fall anger lagstiftningen ett mål eller ett resultat som är önskvärt men där det faktiska agerande inte ange&apos;s. Det sakna&apos;s därmed handlingsregler för aktörerna&apos;s agerande, vilket innebär att aktörerna därmed har utrymme att själva bestämma det faktiska agerandet. I detta handlingsutrymme måste aktörerna förlita sig på andra direktiv än de som lagstiftningen anger; för att hantera detta behöv&apos;s olika former av kunskap. Ett problem som är aktuellt när det gäller kunskap är bland annat att kunskap inte är statisk, utan kan ha olika innehåll beroende på perspektiv och användare. &lt;br/&gt;&lt;br&gt; När det gäller avhandlingen&apos;s syfte nummer två, det vill säga aktörerna&apos;s agerande i förhållande till gällande regleringar, har undersökningen bland annat visat att den lagstiftning som finn&apos;s, och som på olika sätt reglerar specifikt agerande, inte alltid efterlev&apos;s av aktörerna. Att lagstiftningen inte följ&apos;s kan få flera olika konsekvenser. I de fall polisen inte efterlever sin anmälningsskyldighet kan det exempelvi&apos;s innebära att socialtjänsten inte har möjlighet att utreda om barnet är i behov av stöd eller hjälp, eller att socialtjänsten kommer in i ett senare skede än vad som skulle ha varit fallet om polisen enligt lag snarast hade företagit sin anmälan. Detta kan påverka barnet, som dessutom enligt senare forskning benämn&apos;s som särskilt sårbara brottsoffer, bland annat på grund av att barn är beroende av andra människor för att göra sin röst hörd. I detta perspektiv understryk&apos;s aktörerna&apos;s ansvar för barn som brottsoffer. &lt;br/&gt;&lt;br&gt; När det gäller avhandlingen&apos;s sista syfte, rörande påverkansfaktorer i aktörerna&apos;s arbete, är det aktörerna&apos;s berättelser som utgör den huvudsakliga empirin. Det finn&apos;s många olika påverkansfaktorer som kan undersöka&apos;s. Framställningen i detta arbete är avgränsad till de tre områdena: motivation som påverkansfaktor, kunskapsrelaterade påverkansfaktorer och faktiska förutsättningar som påverkansfaktorer . Även om de undersökta faktorerna inte förekommer i renodlad form eller ensamma utgör påverkan på aktörerna&apos;s arbete, har undersökningen utgått från respektive område. Undersökningen visar att de olika faktorerna påverkar aktörerna&apos;s arbete med barn som brottsoffer i olika grad och på olika sätt. Det kan inte säga&apos;s vara en enskild påverkansfaktor som ensam är av betydelse för aktörerna&apos;s agerande. Detta beror för det första på att aktörsgrupperna skiljer sig något åt om man ser till vilka påverkansfaktorer som är betydelsefulla, och för det andra att enskilda påverkansfaktorer&apos;s betydelse och styrka skiftar beroende på situation. Detta betyder sålede&apos;s att ingen av de olika påverkansfaktorerna en gång för alla kan säga&apos;s vara mer betydelsefull än någon annan. Istället har undersökningen visat på det beroendeförhållande som råder mellan de olika påverkansfaktorerna, vilka i aktörerna&apos;s dagliga arbete på olika sätt interagerar och påverkar varandra. Häri har lagstiftningen visat sig utgöra endast en av flera påverkansfaktorer, som ibland har mer, ibland mindre betydelse för aktörerna&apos;s arbete med barn som brottsoffer. En viktig roll lagstiftningen visat sig ha för detta arbete, är att ange foku&apos;s för aktörerna&apos;s arbete, speciellt när olika prioriteringar är nödvändiga. Lagstiftningen kan därmed utgöra en förutsättning för att barn som brottsoffer skall uppmärksamma&apos;s, men är emellertid inte en tillräcklig förutsättning. När aktörerna fattar beslut är det även andra påverkansfaktorer och övervägande som gör sig gällande. Undersökningen har visat att aktörerna vid tillfällen bortser från lagstiftningen, så är exempelvi&apos;s fallet när lagstiftningen anse&apos;s stå i direkt strid med aktörerna&apos;s arbete. Ett sådant exempel utgör förhållandet mellan polisen&apos;s anmälningsskyldighet och socialtjänsten&apos;s skyldighet att underrätta den person utredningen berör om att utredning inlett&apos;s. Detta förhållande understryker även det faktum att aktörerna befinner sig inom olika processer i förhållande till varandra, där det juridiska ansvaret för barnet skiljer sig åt. Huruvida lagstiftningen utgör en betydelsefull påverkansfaktor i aktörerna&apos;s arbete med barn som brottsoffer är även beroende av de faktiska möjligheterna, vilka vid tillfällen visat sig hindra aktörerna&apos;s efterlevnad av lagstiftningen. Ett exempel utgör de förundersökningar och utredningar som tar lång tid, vilket enligt aktörerna bland annat beror på bland annat bristande resurser.&lt;br/&gt;&lt;br&gt; Sålunda är inte endast en god lagstiftning tillräcklig för att arbetet med barn som brottsoffer skall ske utifrån lagstiftningen&apos;s riktlinjer, och i enlighet med lagstiftaren&apos;s intentioner. Som en betydelsefull påverkansfaktor i arbetet med barn som brottsoffer kan därmed även resurser i form av tid för utredningarna, men även aktörerna&apos;s egen inställning till den lagstiftning som finn&apos;s, se&apos;s. &lt;br/&gt;&lt;br&gt; I vilken utsträckning de olika påverkansfaktorerna får verkan och genomslagskraft, beror ytterst på aktören&apos;s individuella beslut . Detta är något som exempelvi&apos;s visar sig i fråga om huruvida aktörerna följer lagstiftningen eller inte, samt hur aktörerna agerar vid resursbrist. &lt;br/&gt;&lt;br&gt; Samtliga påverkansfaktorer har därmed betydelse för aktörerna&apos;s arbete med barn som brottsoffer, och ett helhetsperspektiv är att eftersträva för ett tillfredsställande arbete. Ett helhetsperspektiv, där sålede&apos;s inte endast en av påverkansfaktorerna fokusera&apos;s, eller får utrymme, medför i enlighet med undersökningen att bättre förutsättningar skapa&apos;s för de olika påverkansfaktorerna att samverka. Om påverkansfaktorerna samverkar kan de påverka aktörerna&apos;s arbete i en positiv riktning, istället för att som ovan visat&apos;s kunna motverka varandra. Detta innebär att det är viktigt att det finn&apos;s ett samlat förhållningssätt när man på olika sätt försöker förbättra aktörerna&apos;s arbete med barn som brottsoffer. Att endast koncentrera åtgärder på någon del av aktörerna&apos;s arbete får i enlighet med undersökningen&apos;s resultat begränsad verkan. I detta perspektiv är det viktigt att på olika sätt förbättra lagstiftningen, men om detta gör&apos;s utan att samtidigt möjliggöra för aktörerna att faktiskt utföra arbetet, samt olika former av utbildningsinsatser, är det mindre troligt att arbetet blir i enlighet med lagen&apos;s intentioner, eller lika verkningsfullt. Att anta ett samlat förhållningssätt för att förbättra aktörerna&apos;s arbete med barn som brottsoffer är också viktigt för att de olika påverkansfaktorerna inte skall motverka varandra, såsom ibland visat sig vara fallet med poli&apos;s och socialtjänst. I dessa fall kan aktörerna&apos;s utredningar försvåra&apos;s, och i förlängningen bli sämre genomförda, och därmed kan barnet på olika sätt drabba&apos;s. Brottsofferarbetet kan i ett längre perspektiv även se&apos;s som ett rent brottförebyggande arbete. Forskning visar att det finn&apos;s ett samband mellan dagen&apos;s brottsoffer och morgondagen&apos;s förövare , vilket innebär att det även finn&apos;s ett ekonomiskt incitament för att på ett bra sätt ta hand om dagen&apos;s brottsoffer. Slutligen är ett samlat förhållningssätt för att förbättra aktörerna&apos;s arbete med barn som brottsoffer givetvi&apos;s av stor vikt för varje enskilt barn som kommer i kontakt med aktörerna, och i förlängningen, för samhället i stort. Barnet&apos;s kontakt med samhället&apos;s företrädare har visat sig kunna innebära sådan påverkan på barnet att den efterföljande återhämtningsprocessen försvåra&apos;s, samtidigt som detta kan innebära att (barn som) brottsoffer i ett längre perspektiv inte medverkar i framtida rättsprocesser. Aktörerna&apos;s agerande, och möjligheter att agera, är sålunda av stor vikt.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/1066c1c4-7601-4829-afc9-6120a0664ba9</url> </location> </relatedItem> <originInfo> <publisher>Lund University</publisher> <dateIssued encoding="w3cdtf">2008</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">swe</languageTerm> </language> <subject> <topic>police</topic> <topic>working with Children</topic> <topic>Sociology of Law</topic> <topic>Children as Victims of Crime</topic> <topic>social services</topic> </subject> <subject authority="lup"> <topic>Law</topic> </subject> <relatedItem type="host"> <identifier type="isbn">91-7267-252-8</identifier> <identifier type="oldLupId">934813</identifier> <part> <extent unit="pages"> <total>233</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2008-02-15T10:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>1066c1c4-7601-4829-afc9-6120a0664ba9</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:55+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:55+02:00</recordDateApproved> </recordInfo> </mods>

A rapid and persistent activation of multiple and dynamic inflammatory and immune cascades, in and outside the brain, occurs after stroke. These cascades are believed to affect the progression of the cerebral damage, as well as neural plasticity and functional recovery, but the underlying molecular and cellular determinants remain unclear. The proteins macrophage migration inhibitory factor (MIF) and interferon (IFN)-β are potent regulators of inflammation and immunity, and hence were hypothesized to play a role in stroke pathobiology.&lt;br/&gt;&lt;br&gt; Ischemic stroke, the most common form stroke, often results from the occlusion of the middle cerebral artery (MCA), which can be modelled in rodents. Housing rats subjected to permanent MCAo in an enriched environment, a paradigm that improves sensory-motor function without altering infarct volume, resulted in a down-regulation of MIF around the infarct core, when compared to housing rats in standard cages. Moreover, disruption of the MIF-encoding gene in mice led to both a smaller cerebral infarct volume and a better sensory-motor function during the first week after transient MCAo. Within 3 h to 72 h after MCAo, MIF accumulated in neurons of the penumbra and later peri-infarct region, and pharmacological inhibition of MIF in isolated cerebrocortical neurons conferred protection against ischemia-induced death. Furthermore, abrogation of MIF in mice resulted in a higher galectin-3, a marker of macrophages/microglia, immunoreactivity within the cerebral infarct core but did not affect further hallmarks of the inflammatory and immune response during the first week post-tMCAo. By contrast, deletion of Ifn-β in mice resulted in major alterations of the inflammatory/immune response, including an increase in the number of putative macrophages in the brain and of B cells in the blood and a decrease in plasma interleukins 1β and 5, two days after tMCAo. However, it failed to contribute critically to the behavioural performance of mice over the first week after tMCAo.&lt;br/&gt;&lt;br&gt; Overall, MIF may promote neuronal death and repress the recovery of neurological function after stroke. The results further suggest a role for neuronal MIF in the pathogenesis of stroke, and that the observed MIF-mediated effects might be independent of its pro-inflammatory action. The endogenous expression of IFN-β modulates/ameliorates the inflammatory/immune response, but it does not affect sensory-motor deficits during the first week post-stroke. Future studies will further address the mode(s) of action of MIF and IFN-β in cerebral ischemia.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/dcbb0a36-eaa8-4783-b70e-8396c869cf75</url> </location> </relatedItem> <originInfo> <publisher>Laboratory for Experimental Brain Research</publisher> <dateIssued encoding="w3cdtf">2011</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>interferon-β</topic> <topic>inflammatory/immune cells</topic> <topic>galectin-3</topic> <topic>experimental stroke</topic> <topic>enriched environment</topic> <topic>cytokines</topic> <topic>Brain</topic> <topic>macrophage migration inhibitory factor</topic> <topic>neuroprotection</topic> <topic>reactive astrocytes.</topic> </subject> <subject authority="lup"> <topic>Neurology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86871-12-3</identifier> <identifier type="oldLupId">2203599</identifier> <part> <detail type="volume"> <number>2011:63</number> </detail> <extent unit="pages"> <total>188</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2011-06-16T13:00:00+02:00</dateOther> <note type="additionalInfo">The information about affiliations in this record was updated in December 2015.

This process of adult neurogenesis has been thoroughly documented in several species including birds, rodents and humans. Adult neurogenesis is not a global process, but is confined to two subcompartments of the brain; the subventricular zone lining the lateral ventricles, and the subgranular zone (SGZ) in the hippocampal formation. A variety of stimuli such as voluntary exercise, epileptic seizure activity and inflammation can affect the basal level of neurogenesis. In the course of pathological conditions such as Alzheimer’s disease, multiple sclerosis, epilepsy and stroke, an inflammatory response is initiated in the brain. Prolonged epileptic seizure activity, status epilepticus (SE), strongly imposes on the integrity of the delicate brain structure and cell communication. SE not only induces inflammation, but also neuronal death and a transient increase of basal adult neurogenesis in the hippocampal formation. What role inflammation plays in a disease such as epilepsy, and how it affects the neurons born in the aftermath of seizure activity, is largely unknown. The specific aim of the four studies included in this thesis was to investigate the effect inflammation has on the amount of basal and seizure-induced neurogenesis, and if the morphological development or functional characteristics of new neurons is affected when the neuron is born into an inflammatory environment. In brief, the purpose was to investigate the quantity and quality of the neurogenic outcome in inflammation. To comprehend the interplay between neurogenesis and inflammation would provide a valuable insight into disease progression, and could ultimately be part of the treatment or even a cure for pathological conditions involving seizure activity and inflammation.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/7bd04059-eeb5-4cc7-8832-911ea8df9f7f</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Sara_Bonde_FINAL.pdf">https://portal.research.lu.se/files/3450881/1273392.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">33465433</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Dept of Restorative Neurology, Lund</publisher> <dateIssued encoding="w3cdtf">2009</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>microglia</topic> <topic>hippocampus</topic> <topic>Adult neurogenesis</topic> <topic>gephyrin</topic> <topic>dendritic spines</topic> </subject> <subject authority="lup"> <topic>Other Clinical Medicine</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-86059-89-7</identifier> <identifier type="oldLupId">1272807</identifier> <part> <detail type="volume"> <number>2009:2</number> </detail> <extent unit="pages"> <total>116</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2009-01-16T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>7bd04059-eeb5-4cc7-8832-911ea8df9f7f</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:56+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:56+02:00</recordDateApproved> </recordInfo> </mods>

Some members of these virus families can cause cancer in experimental animals and some are also established as carcinogenic to humans. Detection of specific antibodies to these viruses allows tracking past and present infections to elucidate natural history and association of infection with subsequent disease. As there are more than 150 types of Human papillomaviruses (HPV) and at least 10 Human polyomaviruses (HPyV), the study of antibodies to these virus families require high-throughput methods. Although it is difficult to produce infectious virus stocks of these viruses, so-called pseudovirions that morphologically and immunologically resemble native virions but lack the viral genome can be produced in vitro. In the present thesis, we produced such pseudovirions and used them to i) delineate the importance of hypervariable surface loops for the antigenicity and biological function of the HPV particle ii) developed and validate serological assays for measuring specific antibodies to HPV and Merkel cell polyomavirus (MCPyV) and iii) perform prospective seroepidemio-logical studies to evaluate whether infection with MCPyV was associated with an increased risk for Merkel cell carcinoma. &lt;br/&gt;&lt;br&gt; Site-directed mutagenesis of the surface loops of the HPV capsid found that these loops were essential for the incorporation of the minor capsid protein L2, the genome encapsidation and proper immunogenicity of the particle.&lt;br/&gt;&lt;br&gt; Pseudovirion-based methods were correlated to presence of viral DNA. The pseudovirion neutralization assays and multiplexed assays using pseudovirions bound to heparin-coated fluorescent beads for 21 HPV and 2 HPyV types were correlated with viral DNA for 16 HPV types and MCPyV. MCPyV specific antibody levels in serum were found to be strongly correlated to the MCPyV viral load in skin. Finally, biobank-based seroepidemiological studies found that MCPyV infection was associated with an increased risk for Merkel cell carcinoma (MCC), in particular among females.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/d6df6a74-36c6-42f2-9283-03147b4c07ca</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="H_Faust_final_4.pdf">https://portal.research.lu.se/files/3451011/3216441.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">1914495</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Laboratory Medicine, Medical Microbiology Malmö</publisher> <dateIssued encoding="w3cdtf">2012</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject> <topic>Human papilloma- and polyomaviruses</topic> <topic>pseudovirions</topic> <topic>serology</topic> </subject> <subject authority="lup"> <topic>Microbiology in the Medical Area</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87189-68-5</identifier> <identifier type="oldLupId">3216297</identifier> <part> <detail type="volume"> <number>2012:105</number> </detail> <extent unit="pages"> <total>154</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2012-12-21T09:00:00+01:00</dateOther> <recordInfo> <recordIdentifier>d6df6a74-36c6-42f2-9283-03147b4c07ca</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:57+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-10-27T10:03:21Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:57+02:00</recordDateApproved> </recordInfo> </mods>

Despite all efforts to detect and control prostate cancer at an early stage, a number of men are still progressing to develop incurable metastatic disease. Because of this, development of new methods based on target-specific imaging is becoming increasingly important in the assessment and management of prostate cancer. &lt;br/&gt;&lt;br&gt; The main purpose of this work was to investigate three target antigens: Ku70/Ku80, free prostate specific antigen (fPSA) and ICAM-1, as potential candidates for imaging of prostate cancer using radiolabeled antibodies. The studies were designed to assess the in vivo and ex vivo tumor targeting potential using animal models of prostate cancer. Preclinical SPECT/CT and PET/CT in vivo imaging modalities, ex vivo multi-radionuclide digital autoradiography, ex vivo activity measurements and immunohistochemistry were used to obtain biokinetics and specific activity uptake. &lt;br/&gt;&lt;br&gt; In these studies, we found that radiolabeled INCA-X mAb could efficiently target the Ku70/Ku80 antigen in prostate cancer xenografts in mice that first receive a predose of non-labeled antibody. We also demonstrate that two antibodies specific for fPSA (PSA30 and 5A10) can efficiently target PSA positive prostate cancer xenografts. In that study, we also show that the animal models immune deficiency status can affect the antibody performance. Lastly, we show that 111In-R6.5 mAb outperformed the 177Lu-R6.5 or control IgG mAb and can be used as a complement to clinically used metabolic and proliferative probes. &lt;br/&gt;&lt;br&gt; Our ex vivo and in vivo investigations presented in this dissertation should act as support for further studies of the Ku70/Ku80, fPSA and ICAM-1 antigens. Future studies should include therapeutic applications based on dosimetry calculation to evaluate possible therapeutic efficacy.</abstract> <relatedItem type="constituent"> <location> <url displayLabel="Portal Link">https://portal.research.lu.se/en/publications/f0a3e204-91eb-4ba3-a540-ee35a6592603</url> </location> </relatedItem> <relatedItem type="constituent"> <location> <url displayLabel="Susan_Evans_Axelsson_Kappa_defended_19_Dec_2013.pdf">https://portal.research.lu.se/files/3451187/4178771.pdf</url> </location> <physicalDescription> <internetMediaType>application/pdf</internetMediaType> </physicalDescription> <note type="fileSize">3289899</note> <accessCondition type="restrictionOnAccess">no</accessCondition> </relatedItem> <originInfo> <publisher>Division of Urological Cancers</publisher> <dateIssued encoding="w3cdtf">2013</dateIssued> </originInfo> <language> <languageTerm authority="iso639-2b" type="code">eng</languageTerm> </language> <subject authority="lup"> <topic>Clinical Medicine</topic> <topic>Cancer and Oncology</topic> </subject> <relatedItem type="host"> <titleInfo> <title>Lund University Faculty of Medicine Doctoral Dissertation Series</title> </titleInfo> <identifier type="issn">1652-8220</identifier> <identifier type="isbn">978-91-87651-24-3</identifier> <identifier type="oldLupId">4178770</identifier> <part> <detail type="volume"> <number>2013:149</number> </detail> <extent unit="pages"> <total>58</total> </extent> </part> </relatedItem> <dateOther encoding="w3cdtf" type="defenseDate">2013-12-19T09:15:00+01:00</dateOther> <recordInfo> <recordIdentifier>f0a3e204-91eb-4ba3-a540-ee35a6592603</recordIdentifier> <recordCreationDate encoding="w3cdtf">2016-04-01T13:33:59+02:00</recordCreationDate> <recordChangeDate encoding="w3cdtf">2025-07-28T19:30:29Z</recordChangeDate> <recordDateApproved encoding="w3cdtf">2016-04-01T13:33:59+02:00</recordDateApproved> </recordInfo> </mods>
