Human and murine hematopoietic stem cell aging is associated with functional impairments and intrinsic megakaryocytic/erythroid bias
Aging within the human hematopoietic system associates with various deficiencies and disease states, including anemia, myeloid neoplasms and reduced adaptive immune responses. Similar phenotypes are observed in mice and have been linked to alterations arising at the hematopoietic stem cell (HSC) level. Such an association is, however, less established in human hematopoiesis and prompted us here to
Influence of a School-based Physical Activity Intervention on Cortical Bone Mass Distribution : A 7-year Intervention Study
Cortical bone mass and density varies across a bones length and cross section, and may be influenced by physical activity. This study evaluated the long-term effects of a pediatric school-based physical activity intervention on tibial cortical bone mass distribution. A total of 170 children (72 girls and 98 boys) from one school were provided with 200 min of physical education per week. Three othe
Technical advances of the recombinant antibody microarray technology platform for clinical immunoproteomics
In the quest for deciphering disease-associated biomarkers, high-performing tools for multiplexed protein expression profiling of crude clinical samples will be crucial. Affinity proteomics, mainly represented by antibody-based microarrays, have during recent years been established as a proteomic tool providing unique opportunities for parallelized protein expression profiling. But despite the pro
Association between sickle cell trait and the prevalence and severity of diabetic retinopathy
Purpose To determine whether Sickle cell trait (SCT) is associated with an increased severity of diabetic retinopathy. Methods This was a single center retrospective study case control study of 100 eyes of 100 patients with diabetes mellitus (DM) with SCT (SCT group) and 100 eyes of 100 age-matched patients with DM without SCT (control group). The main outcome measure was the difference in the pre
Diet quality scores and prediction of all-cause, cardiovascular and cancer mortality in a pan-european cohort study
Scores of overall diet quality have received increasing attention in relation to disease aetiology; however, their value in risk prediction has been little examined. The objective was to assess and compare the association and predictive performance of 10 diet quality scores on 10-year risk of all-cause, CVD and cancer mortality in 451,256 healthy participants to the European Prospective Investigat
How Proofs are Prepared at Camelot
We study a design framework for robust, independently verifiable, and workload-balanced distributed algorithms working on a common input. The framework builds on recent noninteractive Merlin--Arthur proofs of batch evaluation of Williams~[31st IEEE Colloquium on Computational Complexity (CCC'16, May 29-June 1, 2016, Tokyo), to appear] with the basic observation that Merlin's magic is not needed fo
Fatty acid profiles of great tit (Parus major) eggs differ between urban and rural habitats, but not between coniferous and deciduous forests
Early-life nutrition is an important determinant of both short- and long-term performance and fitness. The avian embryo develops within an enclosed package of nutrients, of which fatty acids (FA) are essential for many aspects of development. The FA composition of yolk depends on maternal nutrition and condition prior to egg formation, which may be affected by the external environment. To test if
Assessing the effects of repeated handling on the physiology and condition of semi-precocial nestlings
Repeated exposure to elevated levels of glucocorticoids during development can have long-term detrimental effects on survival and fitness, potentially associated with increased telomere attrition. Nestling birds are regularly handled for ecological research, yet few authors have considered the potential for handling-induced stress to influence hormonally mediated phenotypic development or bias int
"Vi har redan tillräckligt med judar här” : tonsättaren Hans Holewa och exilens dubbelhet
Tonsättaren, radiomedarbetaren och musikern Hans Holewa (1905–1991) anlände till Sverige 1937 som landsflyktig undan den tilltagande antisemitismen i Wien, drygt ett halvår innan Österrike annekterades av Nazityskland. Som invandrad radikal tonsättare med den så kallade tolvtonstekniken som utgångspunkt, med judiskt påbrå och med engagemang inom vänsterrörelsen kom Holewas svenska exiltillvaro utg
Myo-inositol changes precede amyloid pathology and relate to APOE genotype in Alzheimer disease
Objective: We aimed to test whether in vivo levels of magnetic resonance spectroscopy (MRS) metabolites myo-inositol (mI), N-acetylaspartate (NAA), and choline are abnormal already during preclinical Alzheimer disease (AD), relating these changes to amyloid or tau pathology, and functional connectivity. Methods: In this cross-sectional multicenter study (a subset of the prospective Swedish BioFIND

The experience of nurses working within a voluntary network : A qualitative study of health care for undocumented migrants
Purpose: To illuminate the experience of nurses providing health care to undocumented migrants in a voluntary network. Methods and sample: In a qualitative study, semistructured interviews were conducted with RNs regarding their experience of providing health care to undocumented migrants within a voluntary network. The interview transcripts were analysed using the inductive method of content anal

Additive domain decomposition operator splittings – convergence analyses in a dissipative framework
We analyze temporal approximation schemes based on overlapping domain decompositions. As such schemes enable computations on parallel and distributed hardware, they are commonly used when integrating large-scale parabolic systems. Our analysis is conducted by first casting the domain decomposition procedure into a variational framework based on weighted Sobolev spaces. The time integration of a pa
