Gas6 promotes inflammation by enhancing interactions between endothelial cells, platelets, and leukocytes

The role of Gas6 in enclothelial cell (EC) function remains incompletely characterized. Here we report that Gas6 amplifies EC activation in response to inflammatory stimuli in vitro. In vivo, Gas6 promotes and accelerates the sequestration of circulating platelets and leukocytes on activated endothelium as well as the formation and enclothelial sequestration of circulating platelet-leukocyte conju

Magnetic CLEAR supports for solid-phase synthesis of peptides and small organic molecules

Paramagnetic versions of the CLEAR supports were prepared by entrapment of magnetite particles during suspension polymerization of allylamine, trimethylolpropane ethoxylate (14/3 EO/OH) triacrylate, and trimethylolpropane trimethacrylate. Swelling studies in a broad range of solvents showed comparable swelling of magnetic beads and regular CLEAR beads. The application of the magnetic beads as the

Time use and occupational performance among persons with schizophrenia

The human occupational/activity pattern is a product of person–occupation–environment interaction, it is of importance to explore all these factors to understand the daily occupational pattern among persons with schizophrenia. This study aimed to describe the time use of 10 persons with schizophrenia, reflecting the participants’ daily occupations, social and geographical environments, and emotion

Elucidating issues stressful for patients in predialysis and dialysis: from symptom to context.

Biopsychosocial problems experienced by renal disease patients were studied within a contextual framework the patients themselves defined, the findings being related to sociodemographic and medical data. Participants were 72 predialysis patients and 73 patients being treated by haemodialysis or peritoneal dialysis (106 men and 39 women, aged 18-84 years). Both stress-related global and situational

Microfluidic biosensing systems - Part II. Monitoring the dynamic production of glucose and ethanol from microchip-immobilised yeast cells using enzymatic chemiluminescent mu-biosensors

A microfluidic flow injection (muFIA) system was employed for handling and monitoring of cell-released products from living cells immobilised on silicon microchips. The dynamic release of glucose and ethanol produced from sucrose by immobilised Saccharomyces cerevisiae cells was determined using microchip biosensors (mu-biosensors) with either co-immobilised glucose oxidase-horseradish peroxidase

Quantification of Membrane Proteins Using Nonspecific Protease Digestions

We present a mass spectrometry-based method for the identification and quantification of membrane proteins using the low-specificity protease Proteinase K, at very high pH, to digest proteins isolated by a modified SDS-PAGE protocol. The resulting peptides are modified with a fragmentation-directing isotope labeled tag. We apply the method to quantify differences in membrane protein expression of

The discursive formation of health. A study of printed health education material used in primary care

This study analyses printed educational material on cholesterol, food and health-related lifestyle changes used in primary care in southern Sweden. Two theoretically grounded perspectives are used: orientation of knowledge and rhetoric. According to the first one, the material contained many examples of abstract and detailed knowledge, such as tables of energy contents, and a little less of action

Perilipin A is essential for the translocation of hormone-sensitive lipase during lipolytic activation

A key step in lipolytic activation of adipocytes is the translocation of hormone-sensitive lipase (HSL) from the cytosol to the surface of the lipid storage droplet. Adipocytes from perilipin-null animals have an elevated basal rate of lipolysis compared with adipocytes from Wild-type mice, but fail to respond maximally to lipolytic stimuli. This defect is downstream of the p-adrenergic receptor-a

Increased CD4+ T cell infiltrates in rheumatoid arthritis-associated interstitial pneumonitis compared with idiopathic interstitial pneumonitis

Objective. To study lymphocyte markers in rheumatoid arthritis (RA)-associated interstitial pneumonitis (IP) compared with idiopathic IP. Methods. Paraffin-embedded lung biopsy specimens from patients with RA (n = 15) and from those without RA (n = 16), all of whom had a diagnosis of either nonspecific IP or usual IP, were studied. Tissue sections from each patient were reviewed by a pathologist,

Analysis of heterocyclic amines in food products: interlaboratory studies

A feasibility study and two interlaboratory exercises on the determination of selected heterocyclic amines (HAs) in beef extract, organised in the framework of a European project, are presented. The aim of these exercises was to improve the quality of the laboratories and to evaluate the performance of a standardised analytical method and also the methods currently used by each of the participants

Diversity, distribution and exchange of blood parasites meeting at an avian moving contact zone

Research on contact zones has paid relatively little attention to host-parasite interactions, although these situations have important but different implications depending on whether one considers the host or the parasite's perspective. We investigated both the role of a host contact zone in parasite expansion and whether parasites could influence contact zone dynamics. We studied the diversity an

Muscle structure and function in chronic neurological disorders: the potential of exercise to improve activities of daily living

Our knowledge of muscle function in chronic neurological disorders, the effects of exercise, and how the effects might translate into improvements in activities of daily living is very limited. By building a bridge between basic muscle physiology and clinical rehabilitation, our knowledge of the pathophysiological mechanisms underlying muscle dysfunction in people with chronic neurological disorde

High-throughput proteomics using antibody microarrays: an update

Antibody-based microarrays are a rapidly emerging technology that has advanced from the first proof-of-concept studies to demanding serum protein profiling applications during recent years, displaying great promise within disease proteomics. Miniaturized micro- and nanoarrays can be fabricated with an almost infinite number of antibodies carrying the desired specificities. While consuming only min

Market behaviour and the to-trade-or-not-to-trade dilemma in 'Tradable White Certificate' schemes

This paper provides an empirical analysis of market behaviour under ‘Tradable White Certificate’ (TWC) schemes. It focuses on the entire set of ‘flexibilities’ granted to obliged parties to meet a mandatory energy-saving target cost-effectively, i.e. range eligible measures, eligible end-use sectors, banking provision, market engagement of non-obliged parties, and trading as such. We found that ma

Gut barrier failure in critical illness: lessons learned from acute pancreatitis

Gut barrier function is essential in critical illness and contributes to the systemic inflammatory response. Failure of the gut barrier includes both changes in microbial ecology, permeability and potential translocation, as well as local gut inflammatory response. The present review summarizes experiences made from acute pancreatitis, including pathophysiological mechanisms and ways of interventi

Fuel use and metabolic response to endurance exercise: a wind tunnel study of a long-distance migrant shorebird

This study examines fuel use and metabolism in a group of long-distance migrating birds, red knots Calidris canutus (Scolopacidae), flying under controlled conditions in a wind tunnel for up to 10 h. Data are compared with values for resting birds fasting for the same time. Plasma levels of free fatty acids, glycerol and uric acid were elevated during flight, irrespective of flight duration (1-10h
