SAD seems to be the best anthropometric predictor of cardiovascular risk, and also of more importance than waist circumference (WC) in adults. There has been no validation studies comparing SAD measured with anthropometric tools (e.g. ruler) to measurements made with more exact devices such as magnetic resonance imaging (MRI) in pediatric age. What this study adds This new reliable method is ideal for children due to limited body contact and no radiation. It is accurate, less expensive than MRI, and also easier to perform than measuring WC. It is easily available for screening purposes making future epidemiological studies possible evaluating health risks related to regional distribution of abdominal tissue. OBJECTIVES: Sagittal diameter (SAD) has been reported to correlate to visceral fat and cardiovascular risk factors. SAD is measured with the individual lying down, halfway between the lower rib margin and the iliac crest; it represents the mid-height of the abdomen. The aim of this study was to validate SAD measured using a recently-developed laser beam device (SAD(LDB) ) against SAD measured using MRI (SAD(MRI) ). METHODS: Of 48 obese children (25 boys, 23 girls) aged 9-11 years on the waiting list for obesity treatment, 34 agreed to a baseline measurement, which was followed by repeated measurements 6 and 12 months later in 31 and 22 children respectively. MRI was used to examine SAD(MRI) at 5 cm above (SAD(MRI) (,cra) ) and below (SAD(MRI) (,cau) ) the mid plane of the L4-5 intervertebral disc. RESULTS: Each of the differences SAD(LBD) - SAD(MRI) (,cau) and SAD(LBD) - SAD(MRI) (,cra) was subjected to a repeated-measurements ANOVA; the visit did not have a statistically significant effect in either case (p = 0.19 and p = 0.72, respectively). The difference SAD(LBD) - SAD(MRI) (,cau) was 1.50 on average (p &lt; 0.0001; CI 1.26-1.74) while the corresponding figure for SAD(LBD) - SAD(MRI) (,cra) was 1.26 (p &lt; 0.0001; CI 1.04-1.49). Regression of the difference on the mean gave slopes of -0.09 (p = 0.25) and -0.04 (p = 0.57) respectively. Prediction of SAD(MRI) from SAD(LDB) can be performed in different ways: by means of linear regression or by means of an additive correction. CONCLUSIONS: Thus, this laser device can be used instead of MRI to estimate SAD by using a simple correction. https://portal.research.lu.se/en/publications/53f90112-b5c4-4119-b6fa-1ea4aac065f3 Wiley-Blackwell 2013 eng Pediatrics http://www.ncbi.nlm.nih.gov/pubmed/23002010?dopt=Abstract yes 2047-6310 3123700 000316328400006 23002010 84878350618 23002010 10.1111/j.2047-6310.2012.00095.x http://dx.doi.org/10.1111/j.2047-6310.2012.00095.x yes 8 2 112 117 https://www.scopus.com/pages/publications/84878350618 53f90112-b5c4-4119-b6fa-1ea4aac065f3 2016-04-01T09:47:25+02:00 2025-10-14T09:31:55+02:00 2016-04-01T09:47:25+02:00 2 info:srw/schema/1/mods-v3.3xml journalArticle published yes 10 Jialei Ye author Junxian Yun author Dong-Qiang Lin author Linhong Xu author Harald Kirsebom author 1961e7e8-a622-4459-9a22-37aeeb76bce4 Shaochuan Shen author Gensheng Yang author Kejian Yao author Yi-Xin Guan author Shan-Jing Yao author Biotechnology v1000653 department A novel super-macroporous monolithic composite cryogel was prepared by embedding macroporous cellulose beads into poly(hydroxyethyl methacrylate) cryogel. The cellulose beads were fabricated by using a microchannel liquid-flow focusing and cryopolymerization method, while the composite cryogel was prepared by cryogenic radical polymerization of the hydroxyethyl methacrylate monomer with poly(ethylene glycol) diacrylate as cross-linker together with the cellulose beads. After graft polymerization with (vinylbenzyl)trimethylammonium chloride, the composite cryogel was applied to separate immunoglobulin-G and albumin from human serum. Immunoglobulin-G with a mean purity of 83.2% and albumin with a purity of 98% were obtained, indicating the composite cryogel as a promising chromatographic medium in bioseparation for the isolation of important bioactive proteins like immunoglobulins and albumins. https://portal.research.lu.se/en/publications/9f931a1f-490a-4244-a7a9-78d6c7791e85 John Wiley & Sons Inc. 2013 eng Bioseparation Cellulose beads Cryogels Immunoglobulin-G Ion-exchange adsorption Industrial Biotechnology 1615-9314 4269100 000328138200001 84890461139 24151195 10.1002/jssc.201300911 http://dx.doi.org/10.1002/jssc.201300911 yes 36 24 3813 3820 https://www.scopus.com/pages/publications/84890461139 9f931a1f-490a-4244-a7a9-78d6c7791e85 2016-04-01T09:47:26+02:00 2025-10-14T10:48:20+02:00 2016-04-01T09:47:26+02:00 3 info:srw/schema/1/mods-v3.3xml journalArticle published yes 6 T.

Wilke author Biodiversity v1000603 department The quality of spatial analyses of biodiversity is improved by (i) utilizing study areas with well defined physiogeographical boundaries, (ii) limiting the impact of widespread species, and (iii) using taxa with heterogeneous distributions. These conditions are typically met by ecosystems such as oceanic islands or ancient lakes and their biota. While research on ancient lakes has contributed significantly to our understanding of evolutionary processes, statistically sound studies of spatial variation of extant biodiversity have been hampered by the frequently vast size of ancient lakes, their limited accessibility, and the lack of scientific infrastructure. The European ancient Lake Ohrid provides a rare opportunity for such a reliable spatial study. The comprehensive horizontal and vertical sampling of a species-rich taxon, the Gastropoda, presented here, revealed interesting patterns of biodiversity, which, in part, have not been shown before for other ancient lakes. <br/><br> <br/><br> In a total of 284 samples from 224 different locations throughout the Ohrid Basin, 68 gastropod species, with 50 of them (= 73.5%) being endemic, could be reported. The spatial distribution of these species shows the following characteristics: (i) within Lake Ohrid, the most frequent species are endemic taxa with a wide depth range, (ii) widespread species (i.e. those occurring throughout the Balkans or beyond) are rare and mainly occur in the upper layer of the lake, (iii) while the total number of species decreases with water depth, the proportion of endemics increases, and (iv) the deeper layers of Lake Ohrid appear to have a higher spatial homogeneity of biodiversity. Moreover, gastropod communities of Lake Ohrid and its feeder springs are both distinct from each other and from the surrounding waters. The analysis also shows that community similarity of Lake Ohrid is mainly driven by niche processes (e.g. environmental factors), but also by neutral processes (e.g. dispersal limitation and evolutionary histories of species). For niche-based mechanisms it is shown that large scale effects such as type of water body or water depth are mainly responsible for the similarity of gastropod communities, whereas small scale effects like environmental gradients affect gastropod compositions only marginally. In fact, neutral processes appear to be more important than the small scale environmental factors, thus emphasizing the importance of dispersal capacities and evolutionary histories of species. https://portal.research.lu.se/en/publications/68c933ce-3bde-4881-8196-4052abc8b6ab Copernicus GmbH 2011 eng Ecology (including Biodiversity Conservation) http://www.scopus.com/inward/record.url?eid=2-s2.0-79551501734&partnerID=40&md5=096b7077b2b870e3823b1332ec9d151a 1726-4189 2440409 79551501734 10.5194/bg-8-175-2011 http://dx.doi.org/10.5194/bg-8-175-2011 yes 8 1 175 188 https://www.scopus.com/pages/publications/79551501734 68c933ce-3bde-4881-8196-4052abc8b6ab 2016-04-01T09:47:27+02:00 2025-10-14T09:23:45+02:00 2016-04-01T09:47:27+02:00 4 info:srw/schema/1/mods-v3.3xml journalArticle published yes 3 Petter Hedelin author David Kylhammar author f4d836d1-d68a-4add-9960-74bd7ed5c39d Göran Rådegran author e8a0258c-89c0-41f0-bdf1-64feb1ea74be Cardiology v1000432 department Aim: Our aim was to test the hypothesis that dual endothelin receptor blockade with tezosentan attenuates hypoxia induced pulmonary vasoconstriction. Methods: 14 anaesthetised, ventilated pigs, with a mean±SEM weight of 30,5±0,6 kg, were studied, in normoxia (FiO(2) â0,21) and with tezosentan (5mg·kg(-1) ) infusion during (n=7) or before (n=7) hypoxia (FiO(2) ∼0,10). Results: Compared to normoxia, hypoxia, increased (p&lt;0,05) pulmonary vascular resistance by 3,4±0,7 WU, mean pulmonary artery pressure by 13,7±1,3 mmHg, mean right atrial pressure by 1,9±0,4 mmHg and decreased (p&lt;0,02) systemic vascular resistance by 5,2±2,1 WU. Pulmonary capillary wedge pressure, mean aortic blood pressure, heart rate, cardiac output, stroke volume and blood-O(2) -consumption were unaltered (p=ns). Tezosentan infused during hypoxia, normalised pulmonary vascular resistance, decreased (p&lt;0,05) maximally mean pulmonary artery pressure by 7,5±0,8 mmHg, systemic vascular resistance by 5,8±0,7 WU, mean aortic blood pressure by 10,8±3,0 mmHg and increased (p&lt;0,04) stroke volume by 8,5±1,8 mL. Mean right atrial pressure, pulmonary capillary wedge pressure, heart rate, cardiac output and blood-O(2) -consumption were unaltered (p=ns). Tezosentan infused before hypoxia additionally attenuated ∼70% of the initial mean pulmonary artery pressure increase and abolished the pulmonary vascular resistance increase, without additionally affecting the other parameters. Conclusion: Dual endothelin receptor blockade during hypoxia, attenuates the "sustained" acute pulmonary vasoconstrictor response by reducing the mean pulmonary artery pressure increase by ∼62% and by normalising pulmonary vascular resistance. Pre-treatment with tezosentan before hypoxia, additionally attenuates the initial hypoxia induced mean pulmonary artery pressure rise by ∼70% and abolishes the pulmonary vascular resistance increase, during stable circulatory conditions, without affecting oxygenation. https://portal.research.lu.se/en/publications/f367bee9-b978-4ee9-b292-8dabe4070f34 Wiley-Blackwell 2012 eng hypoxic pulmonary vasoconstriction pulmonary hypertension vascular tone pulmonary Physiology and Anatomy http://www.ncbi.nlm.nih.gov/pubmed/21726419?dopt=Abstract yes 1748-1708 2059018 000299775100014 21726419 84856557478 21726419 10.1111/j.1748-1716.2011.02339.x http://dx.doi.org/10.1111/j.1748-1716.2011.02339.x yes 204 3 419 434 https://www.scopus.com/pages/publications/84856557478 f367bee9-b978-4ee9-b292-8dabe4070f34 2016-04-01T09:47:28+02:00 2025-10-14T10:47:10+02:00 2016-04-01T09:47:28+02:00 5 info:srw/schema/1/mods-v3.3xml journalArticle published yes 7 Wenxian Li author Zhan Shi author Yang Yang author Jun Xiao author Tomas Brage author fffe21c2-5ec5-4333-b257-5c36c0036643 Roger Hutton author Yaming Zou author Department of Physics v1000621 department We have recorded extreme ultraviolet spectra from W11+ to W15+ ions using a flat-field spectrometer installed at the Shanghai high-temperature superconducting electron-beam ion trap. The spectra were recorded at beam energies ranging between 200 and 400 eV and showed spectral lines and transition arrays in the 170-260 angstrom region. The charge states and spectra transitions were identified by comparison with calculations using a detailed relativistic configuration interaction method and collisional-radiative model, both incorporated in the flexible atomic code. Atomic structure calculations showed that the dominant emission arises from 5d --&gt; 5p and 5p --&gt; 5s transitions. The work also identified the ground-state configuration of W13+ as 4f(13)5s(2) both theoretically and experimentally. https://portal.research.lu.se/en/publications/ff7a3a73-f8d7-4bee-b258-0213d4aea7ef American Physical Society 2015 eng Atom and Molecular Physics and Optics 1050-2947 7410506 000355409200004 84937437706 10.1103/PhysRevA.91.062501 http://dx.doi.org/10.1103/PhysRevA.91.062501 yes 91 6 062501 https://www.scopus.com/pages/publications/84937437706 The information about affiliations in this record was updated in December 2015.

In this work, a discrete formalism is derived along with its implementation via the fast Fourier transform. The implementation takes the intrinsic periodicity of the discrete Fourier transform into consideration, as well as possible inconsistencies that may arise due to discretization and truncation of the functions describing the absorbed dose rate and repair. Numerically and analytically calculated BED values are compared for various situations in external beam radiotherapy, brachytherapy and radionuclide therapy, including the use of different repair models. The numerical method is shown to be accurate and versatile since it can be applied to any kind of absorbed dose rate function and allows for the incorporation of different repair models. Typical accuracies for clinically realistic examples are in the order of 10(-3)% to 10(-5)%. The method has thus the potential of being a useful tool for the calculation of BED, also in situations with complicated irradiation patterns or repair functions. https://portal.research.lu.se/en/publications/7333d106-f769-4071-a8bc-5506cf70b534 IOP Publishing 2013 eng Radiology and Medical Imaging http://www.ncbi.nlm.nih.gov/pubmed/23406832?dopt=Abstract yes 1361-6560 3559831 000315191400023 23406832 84880948891 23406832 10.1088/0031-9155/58/5/1529 http://dx.doi.org/10.1088/0031-9155/58/5/1529 yes 58 5 1529 1548 https://www.scopus.com/pages/publications/84880948891 The information about affiliations in this record was updated in December 2015.

We show that by applying the subthreshold expansion of the scattering amplitudes one can express the finite volume corrections in terms of only a few physical observables and the size of the box. In the case of the nucleon, the available information about the quark mass dependence of these physical quantities is discussed and used to assess the finite volume corrections to the nucleon mass as a function of the quark mass including a detailed analysis of the remaining uncertainties. For heavy mesons, the Luscher formula is derived both fully relativistically and in a nonrelativistic approximation and a first attempt at a numerical analysis is made. https://portal.research.lu.se/en/publications/0076c3db-d9f5-43aa-b6b2-acf7a040aa1f American Physical Society 2010 eng Subatomic Physics 1550-2368 1675228 000280759400003 77956802978 10.1103/PhysRevD.82.034506 http://dx.doi.org/10.1103/PhysRevD.82.034506 yes 82 3 034506 https://www.scopus.com/pages/publications/77956802978 0076c3db-d9f5-43aa-b6b2-acf7a040aa1f 2016-04-01T09:47:29+02:00 2025-10-14T12:25:26+02:00 2016-04-01T09:47:29+02:00 8 info:srw/schema/1/mods-v3.3xml journalArticle published yes 1 Nora Ausmees author 8f3c0c87-1b1b-4dd8-9444-755a0151ab3a Molecular Cell Biology v1000612 department Streptomyces is a multicellular mycelial bacterium, which exhibits pronounced cell polarity and grows by extension of the hyphal tips. Similarly to other polarly growing walled cells, such as filamentous fungi or pollen tubes, Streptomyces hyphae face an intrinsic problem: addition of new cell wall material causes structural weakness of the elongating tip. Cellular strategies employed by walled cells to cope with this problem are not well understood. We have identified a coiled coil protein FilP, with properties similar to those of animal intermediate filament (IF) proteins, which somehow confers rigidity and elasticity to the Streptomyces hyphae. In a recent publication we showed that FilP forms extensive cis-interconnected networks, which likely explain its biological function in determining the mechanical properties of the cells. Surprisingly, the intrinsically non-dynamic cytoskeletal network of FilP exhibits a dynamic behavior in vivo and assembles into growth-dependent polar gradients. We show that apical accumulation of FilP is dependent on its interaction with the main component of the Streptomyces polarisome, DivIVA. Thus, the same polarisome complex that orchestrates cell elongation, also recruits an additional stress-bearing structure to the growing tips with an intrinsically weak cell wall. Similar strategy might be used by all polarly growing walled cells. https://portal.research.lu.se/en/publications/de4678d5-ee3d-4305-a35e-24fe104ad95a Landes Bioscience 2013 eng FilP Streptomyces coiled coil cytoskeleton intermediate filament polar growth Biological Sciences 1949-0992 4066311 24002529 84922395106 10.4161/bioa.26194 http://dx.doi.org/10.4161/bioa.26194 yes 3 4 110 112 https://www.scopus.com/pages/publications/84922395106 de4678d5-ee3d-4305-a35e-24fe104ad95a 2016-04-01T09:47:29+02:00 2025-10-14T09:35:45+02:00 2016-04-01T09:47:29+02:00 9 info:srw/schema/1/mods-v3.3xml journalArticle published yes 1 Alexandros Sopasakis author 15019cdb-2aca-4dd2-a31d-e9c428d42804 Mathematics (Faculty of Engineering) v1000667 department eSSENCE: The e-Science Collaboration v1001240 department We introduce a lattice-free hard sphere exclusion stochastic process. The resulting stochastic rates are distance based instead of cell based. The corresponding Markov chain build for this many particle system is updated using an adaptation of the kinetic Monte Carlo method. It becomes quickly apparent that due to the lattice-free environment, and because of that alone, the dynamics behave differently than those in the lattice-based environment. This difference becomes increasingly larger with respect to particle densities/temperatures. The well-known packing problem and its solution (Palasti conjecture) seem to validate the resulting lattice-free dynamics. https://portal.research.lu.se/en/publications/729c07bb-3acd-4016-bd40-6e2dfebf37cb Global Science Press 2012 eng Lattice-free microscopic stochastic dynamics kinetic Monte Carlo Mathematical Sciences 1991-7120 2826387 000303773200004 84858264637 10.4208/cicp.110211.200611a http://dx.doi.org/10.4208/cicp.110211.200611a yes 12 3 691 702 https://www.scopus.com/pages/publications/84858264637 729c07bb-3acd-4016-bd40-6e2dfebf37cb 2016-04-01T09:47:30+02:00 2025-10-14T12:40:23+02:00 2016-04-01T09:47:30+02:00 10 info:srw/schema/1/mods-v3.3xml journalArticle published yes 4 Thord von Schewelov author c61e5a95-90d4-4b21-9c4f-9c55af69e3eb Åke Carlsson author 27ca355c-9543-4145-a10d-2617037defcf Lennart Sanzén author 68706d7a-02d2-4c69-a5bc-4cd6c6a611fe Jack Besjakov author e8c28ea6-6152-4405-8a47-23ed46a9b78f Orthopedics v1000532 department Radiology Diagnostics, Malmö v1000580 department Orthopedics research group Radiology Diagnostics, Malmö research group In 2005, we demonstrated that the polished triple-tapered C-stem at two years had migrated distally and rotated internally. From that series, 33 patients have now been followed radiologically, clinically and by radiostereometric analysis (RSA) for up to ten years. The distal migration within the cement mantle had continued and reached a mean of 2 mm (0.5 to 4.0) at ten years. Internal rotation, also within the cement mantle, was a mean 3.8° (external 1.6° to internal 6.6°) The cement mantle did not show any sign of migration or loosening in relation to the femoral bone. There were no clinical or radiological signs indicating that the migration or rotation within the cement mantle had had any adverse effects for the patients.

Analysis of the diffraction data shows that in high fields (B≳1.8 T) the spins are not fully aligned, but are canted slightly as a result of the dipolar interaction. The magnetic phase for fields ≲1.8 T is characterized by antiferromagnetic peaks at (210) and an incommensurate wave vector. The dominant contribution to inelastic scattering at large momentum transfers is from a band of almost dispersionless excitations. We show that these correspond to the spin waves localized on ten site rings, expected on the basis of nearest neighbor exchange interaction, and that the spectrum at high fields B≳1.8 T is well described by a spin wave theory. https://portal.research.lu.se/en/publications/ffaa8162-e44f-4122-820b-ba38799d22a7 American Physical Society 2015 eng Subatomic Physics 1079-7114 7727330 26196642 84935901782 26196642 10.1103/PhysRevLett.114.227203 http://dx.doi.org/10.1103/PhysRevLett.114.227203 yes 114 22 227203 https://www.scopus.com/pages/publications/84935901782 ffaa8162-e44f-4122-820b-ba38799d22a7 2016-04-01T09:47:32+02:00 2025-10-14T11:29:26+02:00 2016-04-01T09:47:32+02:00 12 info:srw/schema/1/mods-v3.3xml journalArticle published yes 6 Alexandra Vulcan author 288254de-3de9-4c5f-9d3f-5a22698c51ee Jenny Brändstedt author 8a989ae4-ac24-4481-ac66-6b20bc20580c Jonas Manjer author 43ad32b3-db4d-40be-8bf7-fcdaebf1e011 Karin Jirström author 505ee0e8-4789-46f8-995a-741de2e16b94 Bodil Ohlsson author 5509be42-6397-40a8-a1e3-845d192e15ef Ulrika Ericson author 4b0abbcb-d874-40fd-9ed1-316d2e19ae16 EXODIAB: Excellence of Diabetes Research in Sweden v1001241 department Internal Medicine - Epidemiology v1000520 department Tumor microenvironment v1000471 department Surgery v1000516 department BioCARE: Biomarkers in Cancer Medicine improving Health Care, Education and Innovation v1001237 department Diabetes - Cardiovascular Disease v1000487 department EpiHealth: Epidemiology for Health v1001239 department Internal Medicine - Epidemiology research group Surgery research group Diabetes - Cardiovascular Disease research group Studies on fibre intake and incident colorectal cancer (CRC) indicate inverse associations. Differences by tumour stage have not been examined. We examined associations between fibre intake and its sources, and incidental CRC. Separate analyses were carried out on the basis of sex, tumour location and the Tumour, Node, Metastasis (TNM) classification. The Malmö Diet and Cancer Study is a population-based cohort study, including individuals aged 45-74 years. Dietary data were collected through a modified diet history method. The TNM classification was obtained from pathology/clinical records and re-evaluated. Among 27 931 individuals (60 % women), we found 728 incident CRC cases during 428 924 person-years of follow-up. Fibre intake was inversely associated with CRC risk (P trend=0·026). Concerning colon cancer, we observed borderline interaction between fibre intake and sex (P=0·052) and significant protective association restricted to women (P trend=0·013). Intake of fruits and berries was inversely associated with colon cancer in women (P trend=0·022). We also observed significant interactions between intakes of fibre (P=0·048) and vegetables (P=0·039) and sex on rectal cancer, but no significant associations were seen between intake of fibre, or its sources, in either of the sexes. Except for inverse associations between intake of fibre-rich cereal products and N0- and M0-tumours, we did not observe significant associations with different TNM stages. Our findings suggest different associations between fibre intake and CRC depending on sex, tumour site and fibre source. High fibre intake, especially from fruits and berries, may, above all, prevent tumour development in the colon in women. No clear differences by TNM classification were detected. https://portal.research.lu.se/en/publications/0a4111af-5e69-4bd1-88ca-a5e988c851b5 Cambridge University Press 2015 eng Cancer and Oncology http://www.ncbi.nlm.nih.gov/pubmed/26281852?dopt=Abstract yes 1475-2662 7840735 26281852 000361380600015 84941022914 26281852 10.1017/S0007114515002743 http://dx.doi.org/10.1017/S0007114515002743 yes 114 6 959 969 https://www.scopus.com/pages/publications/84941022914 The information about affiliations in this record was updated in December 2015.

Complete understanding of BR is precluded by the fact that most studies need to assume a respiratory quotient (RQ; mole of CO2 produced per mole of O-2 consumed) to calculate rates of BR. Many studies have, without clear support, assumed a fixed RQ around 1. Here we present 72 direct measurements of bacterioplankton RQ that we carried out in epilimnetic samples of 52 freshwater sites in Quebec (Canada), using O-2 and CO2 optic sensors. The RQs tended to converge around 1.2, but showed large variability (s.d.=0.45) and significant correlations with major gradients of ecosystem-level, substrate-level and bacterial community-level characteristics. Experiments with natural bacterioplankton using different single substrates suggested that RQ is intimately linked to the elemental composition of the respired compounds. RQs were on average low in net autotrophic systems, where bacteria likely were utilizing mainly reduced substrates, whereas we found evidence that the dominance of highly oxidized substrates, for example, organic acids formed by photo-chemical processes, led to high RQ in the more heterotrophic systems. Further, we suggest that BR contributes to a substantially larger share of freshwater CO2 emissions than presently believed based on the assumption that RQ is similar to 1. Our study demonstrates that bacterioplankton RQ is not only a practical aspect of BR determination, but also a major ecosystem state variable that provides unique information about aquatic ecosystem functioning.

The aim of this study was to investigate whether cortical porosity is associated with prevalent fractures in older men. A subsample of 456 men aged 80.2 +/- 3.5 (mean +/- SD) years, with available high-resolution peripheral quantitative computed tomography measurements at the tibia from the 5-year follow-up exam, was drawn from the prospective MrOS Gothenburg study. Dual-energy X-ray absorptiometry was used to measure areal bone mineral density (aBMD). Data on physical activity, calcium intake, medications, diseases, and smoking were collected on questionnaires at the follow-up exam. Of 87 men (19.1%) with fracture at or after age 50 years (all fracture group), 52 (11.4%) had had a self-reported fracture before the baseline exam and 35 (7.7%) had had an X-ray-verified fracture between baseline and follow-up. Men in the all-fracture group and in the X-ray-verified group had 15.8% (13.2%+/- 4.9% versus 11.4%+/- 3.8%; p &lt; 0.001) and 21.6% (14.1%+/- 5.2% versus 11.6%+/- 3.9%; p &lt; 0.01) higher cortical porosity, respectively, than men in the nonfracture group. The independent associations between bone microstructure parameters and fracture were tested using multivariate logistic regression with age, height, weight, calcium intake, smoking, physical activity, medications, and diseases as covariates. Cortical porosity was independently associated with any fracture (reported or X-ray-verified; OR per SD increase 1.49; 95% confidence interval (CI), 1.17 to 1.90) and with any X-ray-verified fracture alone (OR 1.73; 95% CI, 1.23 to 2.42). Including aBMD (spine or hip, respectively) in the multivariate logistic regression above revealed that cortical porosity was associated with any fracture (OR 1.54; 95% CI, 1.17 to 2.01) and with X-ray-verified fracture alone (OR 1.49; 95% CI, 1.00 to 2.22). Cortical porosity was associated with prevalence of fracture even after adjustment for aBMD.

This is partly due to the scarcity of available change detection algorithms suitable for identifying and characterizing both abrupt and non-abrupt changes, without sacrificing accuracy or computational speed. We propose a user-friendly program for analysing vegetation time series, with two main application domains: generalising vegetation trends to main features, and characterizing vegetation trend changes. This program, Detecting Breakpoints and Estimating Segments in Trend (DBEST) uses a novel segmentation algorithm which simplifies the trend into linear segments using one of three user-defined parameters: a generalisation-threshold parameter δ, the m largest changes, or a threshold β for the magnitude of changes of interest for detection. The outputs of DBEST are the simplified trend, the change type (abrupt or non-abrupt), and estimates for the characteristics (time and magnitude) of the change. DBEST was tested and evaluated using simulated Normalized Difference Vegetation Index (NDVI) data at two sites, which included different types of changes. Evaluation results demonstrate that DBEST quickly and robustly detects both abrupt and non-abrupt changes, and accurately estimates change time and magnitude.<br/><br> <br/><br> DBEST was also tested using data from the Global Inventory Modeling and Mapping Studies (GIMMS) NDVI image time series for Iraq for the period 1982–2006, and was able to detect and quantify major change over the area. This showed that DBEST is able to detect and characterize changes over large areas. We conclude that DBEST is a fast, accurate and flexible tool for trend detection, and is applicable to global change studies using time series of remotely sensed data sets. https://portal.research.lu.se/en/publications/218c4b41-46fd-4e23-b8b8-65df0d546bd4 Elsevier 2015 eng trend analysis satellite imagery segmentation time series NDVI GIMMS DBEST change detection vegetation dynamics Physical Geography http://www.sciencedirect.com/science/article/pii/S0034425714003538 yes 0034-4257 4698732 000347579900015 84908316467 10.1016/j.rse.2014.09.010 http://dx.doi.org/10.1016/j.rse.2014.09.010 yes 156 January 182 195 https://www.scopus.com/pages/publications/84908316467 218c4b41-46fd-4e23-b8b8-65df0d546bd4 2016-04-01T09:47:35+02:00 2026-02-25T10:23:37+01:00 2016-04-01T09:47:35+02:00 17 info:srw/schema/1/mods-v3.3xml journalArticle published yes 5 Lars Ekblad author f8a742a9-1db9-4d43-aded-f499555f49b7 Charlotte Welinder author a55b4bb5-2662-4c50-b53c-5a8a011b8a93 Elisabeth Kjellén author 95775bb4-2374-4f3d-9705-bdc85040a237 Eva Brun author 86b60f55-22a4-4a58-a6ec-be0d73f182b4 Johan Wennerberg author 253b71ac-0537-4bd1-b837-c6d2a0faacb2 Tumor microenvironment v1000471 department Head and Neck Cancer Research Group v1001079 department BioCARE: Biomarkers in Cancer Medicine improving Health Care, Education and Innovation v1001237 department Otorhinolaryngology (Lund) v1000461 department Head and Neck Cancer Research Group research group Cetuximab is an epidermal growth factor receptor (EGFR)-targeting drug that has shown effects in head and neck squamous cell carcinoma (HNSCC).

Two series of fully aromatic copolymers are prepared by coupling reactions between non-sulfonated hydrophobic precursor blocks and highly sulfonated hydrophilic precursor blocks containing either fully disulfonated diarylsulfone or fully tetrasulfonated tetraaryldisulfone segments. The sulfonic acid groups are exclusively introduced in ortho positions to the sulfone bridges to impede desulfonation reactions, and give the blocks ion exchange capacities (IECs) of 4.1 and 4.6 meq./g, respectively. Solvent cast block copolymer membranes show well-connected hydrophilic nanophase domains for proton transport and high decomposition temperatures above 310 ˚C under air. Despite higher IEC values, membranes containing tetrasulfonated tetraaryldisulfone segments display a markedly lower water uptake than the corresponding ones with disulfonated diarylsulfone segments when immersed in water at 100 ˚C, presumably because of the much higher chain stiffness and glass transition temperature of the former segments. The former membranes have proton conductivities in level of a perfluorosulfonic acid membrane (NRE212) under fully humidified conditions. A membrane with an IEC of 1.83 meq./g reaches above 6 mS/cm under 30% relative humidity at 80 ˚C, to be compared with 10 mS/cm for NRE212 under the same conditions. https://portal.research.lu.se/en/publications/3fdb8b6c-e366-4e04-80eb-cc672a321dcc Wiley-Blackwell 2012 eng ionomer block copolymer polyelectrolyte sulfonation polycondensation water transport fuel cell membrane Chemical Sciences 1614-6832 2171969 000298982500018 84859763494 10.1002/aenm.201100515 http://dx.doi.org/10.1002/aenm.201100515 yes 2 1 129 140 https://www.scopus.com/pages/publications/84859763494 The information about affiliations in this record was updated in December 2015.
