In elderly man, low serum 25-hydroxyvitamin D (25(OH)D) was associated with a substantial excess risk of death compared to 25(OH)D values greater than 50-70 nmol/l, but the association attenuated with time. The aim of the present study was to determine whether poor vitamin D status was associated with an increase in the risk of death in elderly men. We studied the relationship between serum 25(OH)
Recension av två doktorsavhandlingar.This review scrutinizes two doctoral dissertations at Lund University, one in Historical Archaeology, the other in Latin. Both are deemed to deserve high praise.
Topology optimization at finite strain setting using the concept of inverse motion based form finding is introduced. This novel procedure allows boundary conditions and shape of the structure in the operating, deformed, state to be prescribed. The outcome of the optimization algorithm will be the shape of the undeformed structure, i.e. the state in which the structure should be manufactured. The o
In the 1990s, several public corruption scandals were uncovered in Sweden. This article focuses specifically on local corruption, and our purpose is to examine whether a case can be made that problems of public corruption in Swedish municipalities have increased. By applying instruments from the institutional rational choice framework, we reach the conclusion that there are indeed reasons to suspe
The fact that 10% of female mice enter oestrus and allow mating in the middle of the day is an old observation that has been more or less forgotten. We here show that this old knowledge can be used to improve the efficacy of both embryo transfer and insemination protocols. The present technical paper shows that rapid re-arrangements of mating cages, to achieve pseudo-pregnant recipients in the mid
Herein we investigated the association between polymorphisms in the LRP5 gene and bone phenotypes and fractures in three large male cohorts based on the rationale that mutations in LRP5 cause severe bone phenotypes. Results showed an association of the Val667Met SNP with spine BMD in 3,800 young and elderly men. INTRODUCTION: The low-density lipoprotein receptor-related protein 5 (LRP5)-Wnt signal
OBJECTIVE-Our previous studies suggest that the SNARE protein synaptosomal-associated protein of 23 kDa (SNAP23) is involved in the link between increased lipid levels and insulin resistance in cardiomyocytes. The objective was to determine whether SNAP23 may also be involved in the known association between lipid accumulation in skeletal muscle and insulin resistance/type 2 diabetes in humans, as
We consider model predictive control (MPC) problems with linear dynamics, polytopic constraints, and quadratic objective. The resulting optimization problem is solved by applying an accelerated gradient method to the dual problem. The focus of this paper is to provide bounds on the number of iterations needed in the algorithm to guarantee a prespecified accuracy of the dual function value and the
Recent finds of the leafcutting bee Megachile lagopoda (Linnaeus) in Åhus, Scania in Southern Sweden are presented. This species has drastically decreased in Sweden since 1970, and is now considered vulnerable (VU) on the Swedish redlist.
This article is concerned with the correlation between credibility and the concept of sovereignty in international law and their relationship to truth. Empirically, the authors focus on the credibility assessment informing the refugee determination procedure operated by the Office of the UN High Commissioner of Refugees. The authors do not provide a rationalised explanation of credibility assessme
Context. A long-held vision has been to realize diffraction-limited optical aperture synthesis over kilometer baselines. This will enable imaging of stellar surfaces and their environments, and reveal interacting gas flows in binary systems. An opportunity is now opening up with the large telescope arrays primarily erected for measuring Cherenkov light in air induced by gamma rays. With suitable s
Autoantibodies against the newly established autoantigen in type 1 diabetes, zinc transporter 8, ZnT8, are presented as two types, ZnT8RAb and ZnT8WAb. The rs13266634 variant of the SLC30A8 gene has recently been found to determine the type of ZnT8Ab. The aim of this study was to explore the impact of this genetic variant and the ZnT8Ab on the residual beta-cell function during disease progression
Specific parameters of the neuronal tissue microstructure, such as axonal diameters, membrane permeability and intracellular water fractions are assessable using diffusion MRI. These parameters are commonly estimated using analytical models, which may introduce bias in the estimated parameters due to the approximations made when deriving the models. As an alternative to using analytical models, a
Type 2 diabetes (T2D) is a disease characterised by varying degrees of defect in insulin secretion and insulin sensitivity and associated with increased morbidity and mortality. Optimal glycaemic control reduces the progression of diabetic complications. Over time, there is a steady deterioration of glycaemic control that raises the need for effective therapy targeted at the underlying defects in
Objective . To evaluate the clinical performance in a paediatric population of the Lund-Malmo creatinine-based glomerular filtration rate (GFR) prediction equations, primarily developed for adults. Material and methods . Iohexol clearance was used as the gold standard in 85 paediatric Caucasian patients (0.3-17 years; 37 F/48 M). One Lund-Malmo equation was based on age and gender (LM) and one inc
In this paper a particular case of grammatical gender agreement system is discussed, concerning the referent of young females or small children. These referents are grammatically treated as neuter nouns, disregarding their biological sex. This is termed gender disagreement. It is argued here that this is due to the older classification of nouns based on active and inactive distinction, stemming fr
This correspondence deals with the construction of minimum Euclidean distance precoders for multiple-input multiple-output (MIMO) systems with up to four transmit antennas. By making use of a state-of-the-art technique for optimization over the unitary group, we can numerically optimize the MIMO precoders. The correspondence then proceeds by identifying the obtained precoders as well-known lattice
