Evidence that autonomic mechanisms contribute to the adaptive increase in insulin secretion during dexamethasone-induced insulin resistance in humans.

AIMS/HYPOTHESIS: This study examined whether autonomic mechanisms contribute to adaptively increased insulin secretion in insulin-resistant humans, as has been proposed from studies in animals. METHODS: Insulin secretion was evaluated before and after induction of insulin resistance with or without interruption of neural transmission. Insulin resistance was induced by dexamethasone (15 mg given ov

Respiratory indices by gas analysis and fat metabolism by indirect calorimetry in normal subjects and triathletes.

Summary Background: The effects of exercise on different indices reflecting the metabolism have been of interest for a long time, and a relationship between anaerobic indices and maximal oxygen uptake has been established. The inter-relationship between different respiratory indices during an exercise test remains to be studied in order to understand differences between individuals. Therefore, the

Safety and pharmacokinetics of subcutaneously administered recombinant activated factor VII (rFVIIa).

Background: Recombinant factor VIIa (rFVIIa) is used to treat bleeds in hemophilia patients with inhibitors. A subcutaneous formulation could potentially improve its half-life and make it suitable for prophylactic treatment. Objectives: A study was conducted to determine the safety of subcutaneously administered rFVIIa in patients with hemophilia and the pharmacokinetic profile (including bioavail

Survival at 19 years of age in a total population of children and young people with cerebral palsy.

Aim The aims were to investigate survival of children with cerebral palsy (CP) and to search for modifiable factors that influence survival in CP. Method The total population of children with CP in southern Sweden born between 1990 and 2005, and followed from 1994 to 2010 comprised 718 children. The study included 708 of these children (297 females, 411 males) participating in a secondary preventi

Activator protein-1 in carotid plaques is related to cerebrovascular symptoms and cholesteryl ester content.

INTRODUCTION: Transcription factor activator protein-1 regulates genes involved in inflammation and repair. The aim of this study was to determine whether transcription factor activator protein-1 activity in carotid plaques is related to symptoms, lipid accumulation, or extracellular matrix composition. METHODS: Twenty-eight atherosclerotic carotid plaques were removed by endarterectomy and divide

Reconstruction of diffuse photon-density wave interference in turbid media from time-resolved transmittance measurements

We demonstrate an improved technique to precisely localize inhomogeneities in turbid media by means of reconstructing diffuse photon-density wave interference from time-resolved transmittance measurements applying the Fourier transform. This interference can also be obtained in the reverse mode, that is using a single source and combining the signals detected at several locations. This increases t

Virtual bioinformatics distance learning suite*.

Distance learning as a computer-aided concept allows students to take courses from anywhere at any time. In bioinformatics, computers are needed to collect, store, process, and analyze massive amounts of biological and biomedical data. We have applied the concept of distance learning in virtual bioinformatics to provide university course material over the Internet. Currently, we provide two fully

Long-term prophylaxis in severe haemophilia seems to preserve bone mineral density.

It has been previously shown that patients with severe haemophilia and not receiving any prophylactic treatment render a high risk of reduced bone mineral density. The purpose of this study was to evaluate bone mineral density (BMD) in patients with haemophilia of different severity types and treatment. The study group consisted of 26 patients with severe haemophilia (aged 33.6 +/- 2.1) and 16 pat

Infusion fluids contain harmful glucose degradation products.

PURPOSE: Glucose degradation products (GDPs) are precursors of advanced glycation end products (AGEs) that cause cellular damage and inflammation. We examined the content of GDPs in commercially available glucose-containing infusion fluids and investigated whether GDPs are found in patients' blood. METHODS: The content of GDPs was examined in infusion fluids by high-performance liquid chromatograp

Two-dimensional electronic spectroscopy of the B800-B820 light-harvesting complex

Emerging nonlinear optical spectroscopies enable deeper insight into the intricate world of interactions and dynamics of complex molecular systems. 2D electronic spectroscopy appears to be especially well suited for studying multichromophoric complexes such as light-harvesting complexes of photosynthetic organisms as it allows direct observation of couplings between the pigments and charts dynamic

Prevalence of symptoms in relation to androgen concentrations in women using estrogen plus progestogen and women using estrogen alone.

OBJECTIVE:: Women using estrogen plus progestogen therapy sometimes report difficult to describe symptoms, eg, changes in libido, mood, and memory, that may be related to decreased androgens. To evaluate the prevalence of such symptoms and relate these symptoms to androgen levels in women using estrogen plus progestogen therapy, data from the Women's Health in the Lund Area Study were analyzed. DE

Absence of adenosine A(1) receptors unmasks pulses of insulin release and prolongs those of glucagon and somatostatin.

AIMS: Extracellular ATP modulates pulsatile release of insulin, glucagon and somatostatin by activating P2Y(1) receptors. The present study examines if adenosine via A(1) receptors (A(1)R) interferes with pulsatile islet hormone release. MAIN METHODS: Pancreas was perfused in mice expressing or lacking the A(1) receptor and the hormones measured with radioimmunoassay. Cytoplasmic Ca(2+) was record

Epidemiology of aniridia in Sweden and Norway.

Purpose: To investigate the epidemiology of aniridia in the populations of Sweden and Norway. Methods: A thorough search for aniridia patients has been performed in Sweden and Norway. All participants had a clinical ophthalmological examination documented through photography. Blood samples were taken for mutation analysis and pedigrees were established. Results: A total of 181 patients with anirid

SufA of the opportunistic pathogen Finegoldia magna modulates actions of the antibacterial chemokine MIG/CXCL9, promoting bacterial survival during epithelial inflammation.

The anaerobic bacterium Finegoldia magna is part of the human commensal microbiota, but is also an important opportunistic pathogen. This bacterium expresses a subtilisin-like serine-proteinase, SufA, which partially degrade the antibacterial chemokine MIG/CXCL9. Here, we show that MIG/CXCL9 is produced by human keratinocytes in response to inflammatory stimuli. In contrast to the virulent human p
