The structure of allozyme variation in Silene nutans (Caryophyllaceae) in Denmark and in north-western Europe

We used allozymes to investigate the structure of genetic variation in populations of the perennial herb Silene nutans at local (Denmark), regional (Nordic area) and wide (over a 19A degrees latitudinal gradient) geographic scales in north-western Europe. New data from Denmark were combined with data from previously studied Fennoscandian and western populations. We related patterns of nuclear vari

Interactive effects of landscape history and current management on dispersal trait diversity in grassland plant communities

Summary Plant communities and their ecosystem functions are expected to be more resilient to future habitat fragmentation and deterioration if the species comprising the communities have a wide range of dispersal and persistence strategies. However, the extent to which the diversity of dispersal and persistence traits in plant communities is determined by the current and historical characteristic

Giant prolactinomas in women

Objective: To characterise distinctive clinical features of giant prolactinomas in women. Design: A multicentre, retrospective case series and literature review. Methods: We collected data from 15 female patients with a pituitary tumour larger than 4 cm and prolactin levels above 1000 mu g/l and identified 19 similar cases from the literature; a gender-based comparison of the frequency and age dis

Cord blood insulinoma-associated protein 2 autoantibodies are associated with increased risk of type 1 diabetes in the population-based Diabetes Prediction in Skane study

Aims/hypothesis The aim of this study was to examine the effect of cord blood autoantibodies on the risk for type 1 diabetes in children followed prospectively from birth. Methods The Diabetes Prediction in Skane (DiPiS) study consists of 35,853 children from the general population born during 2000-2004. Samples were collected at birth and analysed for HLA genotypes and autoantibodies to glutamate

ApoLänk decreases patient medication discrepancies at discharge: initial experience from a Swedish bedside pharmacy service

Objective: To develop a working model so that dispensing pharmacists, patients and medical staff can work together to identify, solve and prevent problems associated with discharge prescriptions. Method: A routine was developed for communication between pharmacists, patients and medical staff and for dispensing drugs at the bedside. Hospital medication lists and prescriptions from the pharmacy a

Mutation Update for the PORCN Gene

Mutations in the PORCN gene were first identified in Goltz-Gorlin syndrome patients in 2007. Since then, several reports have been published describing a large variety of genetic defects resulting in the Goltz-Gorlin syndrome, and mutations or deletions were also reported in angioma serpiginosum, the pentalogy of Cantrell and Limb-Body Wall Complex. Here we present a review of the published mutati

Transient biochar effects on decomposer microbial growth rates: evidence from two agricultural case-studies

We investigated the impact of biochar application on fungal (acetate incorporation into ergosterol) and bacterial (leucine incorporation) growth rates in two case studies: a temperate UK pasture soil and a Mediterranean Australian agricultural soil. We added biochar at similar rates per unit of soil organic carbon (SOC) and monitored both the immediate (after 1week equilibration) and longer-term (

The International Proteomics Tutorial Programme (IPTP):A teaching tool box for the proteomics community.

The most critical functions of the various proteomics organisations are the training of young scientists and the dissemination of information to the general scientific community. The education committees of the Human Proteome Organisation (HUPO) and the European Proteomics Association (EuPA) together with their national counterparts are therefore launching the International Proteomics Tutorial Pro

Plasma concentrations of apolipoproteins A-I, B, and M in patients with abdominal aortic aneurysms.

Objectives: Apolipoproteins play important roles in the development of atherosclerosis but their involvement in the pathogenesis of abdominal aortic aneurysm (AAA) is poorly understood. The aim was to investigate whether apoA-I, apoB and apoM are independently associated with AAA. Design and methods: Plasma apoA-I, apoB and apoM were measured in 343 patients with AAA and in 214 elderly apparently

Low expression and secretion of circulating soluble CTLA-4 in peripheral blood mononuclear cells and sera from type 1 diabetic children

Background High levels of soluble cytotoxic T-lymphocyte antigen 4 (soluble CTLA-4), an alternative splice form of the regulatory T-cell (Treg) associated CTLA-4 gene, have been associated with type 1 diabetes (T1D) and other autoimmune diseases, such as Grave's disease and myasthenia gravis. At the same time, studies have shown soluble CTLA-4 to inhibit T-cell activation through B7 binding. This

Hypoxic induction of vascular endothelial growth factor regulates erythropoiesis but not hematopoietic stem cell function in the fetal liver.

Hypoxia is an important factor in the hematopoietic stem cell (HSC) niche in the bone marrow, but whether it also plays a role in the regulation of fetal liver (FL) HSCs is unclear. Vascular endothelial growth factor A (VEGFA) is essential for adult HSC survival, and hypoxic induction of VEGFA in adult HSCs is required for proper function. Loss of hypoxia-regulated VEGFA expression increases the n

Association of LRRK2 exonic variants with susceptibility to Parkinson's disease: a case-control study

Background The leucine-rich repeat kinase 2 gene (LRRK2) harbours highly penetrant mutations that are linked to familial parkinsonism. However, the extent of its polymorphic variability in relation to risk of Parkinson's disease (PD) has not been assessed systematically. We therefore assessed the frequency of LRRK2 exonic variants in individuals with and without PD, to investigate the role of the

The probability of patients being admitted from the emergency department is negatively correlated to in-hospital bed occupancy - a registry study.

The association between emergency department (ED) overcrowding and poor patient outcomes is well described, with recent work suggesting that the phenomenon causes delays in time-sensitive interventions, such as resuscitation. Even though most researchers agree on the fact that admitted patients boarding in the ED is a major contributing factor to ED overcrowding, little work explicitly addresses w

The European treatment of severe atopic eczema in children taskforce (TREAT) survey

BackgroundThere is a paucity of evidence for the use of systemic agents in children with atopic eczema refractory to conventional therapy, resulting in considerable variation in patient management. ObjectivesThe European TREatment of severe Atopic eczema in children Taskforce (TREAT) survey was established to collect data on current prescribing practice, to identify factors influencing the use of

Involvement of Matrix Metalloproteinase-9 in Amyloid-β 1-42-Induced Shedding of the Pericyte Proteoglycan NG2.

Deposition of amyloid-β (Aβ) 1-42, the major component of senile plaques characteristic of Alzheimer disease, affects brain microvascular integrity and causes blood-brain barrier dysfunction, increased angiogenesis, and pericyte degeneration. To understand the cellular events underlying Aβ1-42 effects on microvascular alterations, we investigated whether different aggregation forms of Aβ1-42 affec

Translational approach for gene therapy in epilepsy: Model system and unilateral overexpression of neuropeptide Y and Y2 receptors.

Although novel treatment strategies based on the gene therapy approach for epilepsy has been encouraging, there is still a gap in demonstrating a proof-of-concept in a clinically relevant animal model and study design. In the present study, a conceptually novel framework reflecting a plausible clinical trial for gene therapy of temporal lobe epilepsy was explored: We investigated (i) whether the p
