Circulating insulin is dependent on a balance between insulin appearance through secretion and insulin clearance. However, to what extent changes in insulin clearance contribute to the increased insulin levels after glucagon administration is not known. This study therefore assessed and quantified any potential effect of glucagon on insulin kinetics in mice. Prehepatic insulin secretion in mice wa

The detailed nature of electronic states mediating ferromagnetic coupling in dilute magnetic semiconductors, specifically (Ga,Mn)As, has been an issue of long debate. Two confronting models have been discussed emphasizing host band versus impurity band carriers. Using angle resolved photoemission we show that the electronic structure of the (Ga,Mn)As system is significantly modified from that of G

Background and aims Chronic kidney disease leads to uremia and markedly accelerates atherosclerosis. Phenotypic modulation of smooth muscle cells (SMCs) in the arterial media plays a key role in accelerating atherogenesis. The aim of this study was to investigate whether uremia per se modulates the phenotype of aortic SMCs in vivo. Methods Moderate uremia was induced by 5/6 nephrectomy in apolipop

Background Microsatellite instability arises due to defect mismatch repair (MMR) and occurs in 10–20% of sporadic colorectal cancer. The purpose was to investigate correlations between defect MMR, prognosis and heredity for colorectal cancer in first-degree relatives. Material and methods Tumour tissues from 318 patients consecutively operated for colorectal cancer were analysed for immunohistoche

Foot problems complicating diabetes are a source of major patient suffering and societal costs. To prevent, or at least reduce, the adverse effects of foot problems in diabetes, the International Working Group on the Diabetic Foot (IWGDF; www.iwgdf.org) was founded in 1996, consisting of experts from almost all the disciplines involved in the care of patients with diabetes and foot problems. An im

The discovery of reliable biomarkers to predict efficacy and toxicity of anticancer drugs remains one of the key challenges in cancer research. Despite its relevance, no efficient study designs to identify promising candidate biomarkers have been established. This has led to the proliferation of a myriad of exploratory studies using dissimilar strategies, most of which fail to identify any promisi

Ineffective antimicrobial therapy of Pseudomonas aeruginosa bacteraemia increases mortality. Recent studies have proposed the use of antimicrobial combination therapy composed of a beta-lactam with either ciprofloxacin or tobramycin. To determine if combination therapy correlates to lower mortality and is superior compared to monotherapy, we investigated the effect of antimicrobial treatment regim

Background: B-cells are essential in immunity against malaria, but which sub-sets of B-cells specifically recognize Plasmodium falciparum and when they appear is still largely unknown. Results: Using the flow cytometry technique for detection of P. falciparum specific (Pf+) B-cells, this study for the first time measured the development of Pf+ B cell (CD19+) phenotypes in Ugandan babies from birth

En unik samling medeltida skatter från skånska kyrkor finns bevarade till våra dagar. Dessa liturgiska föremål som använts i gudstjänstens cermoniel, beskrivs här i ord och bild. Guldsmedernas och bronsgjutarnas praktfulla alster belyses utifrån sin funktion och sitt stilhistoriska sammanhang. Personliga ägodelar såsom smycken och pilgrimsmärken ger oss samtidigt en inblick i hur den kristna kultu

Ett nyupptäckt medeltida stenhus i Färlövs kyrkby, Östra Göinge, blev hösten 2011 föremål för en kortvarig, inledande undersökning. En välbevarad, aristokratiskt präglad anläggning har börjat framträda, i ett läge strax väster om Färlövs romanska stenkyrka med sina välkända tvillingtorn. En medeltida huvudgård i kyrkbyn är känd i dokumenten, och här finns ett ännu något oklart men intressant samba

Severe infections are recognized complications of coeliac disease (CD). In the present study we aimed to examine whether individuals with CD are at increased risk of invasive pneumococcal disease (IPD). To do so, we performed a population-based cohort study including 29 012 individuals with biopsy-proven CD identified through biopsy reports from all pathology departments in Sweden. Each individual
