Transglutaminase and the pathogenesis of coeliac disease.

In 1997, a German group demonstrated that the antigen of the biomarker EMA (endomysial antibodies) in coeliac disease is a calcium-dependent thiol enzyme, transglutaminase type 2 (TG2). This most important discovery opened up an exciting field of research aimed at a better understanding of the pathogenesis of coeliac disease, a T-cell-driven autoimmune disorder with a prevalence of about 1%. The a

Laminins.

Laminins are cell adhesion molecules that comprise a family of glycoproteins found predominantly in basement membranes, which are the thin sheets of extracellular matrix that underlie epithelial and endothelial cells and surround muscle cells, Schwann cells, and fat cells. Many laminins self-assemble to form networks that remain in close association with cells through interactions with cell surfac

Simvastatin protects against T cell immune dysfunction in abdominal sepsis.

ABSTRACT: Sepsis-triggered immune paralysis including T-cell dysfunction increases susceptibility to infections. Statins exert beneficial effects in patients with sepsis, although the mechanisms remain elusive. Herein, we hypothesized that simvastatin may attenuate T-cell dysfunction in abdominal sepsis. Male C57BL/6 mice were pretreated with simvastatin (10 mg/kg) before cecal ligation and punctu

Inhalation of LPS induces inflammatory airway responses mimicking characteristics of chronic obstructive pulmonary disease.

Aim: Inhalation of lipopolysaccharide (LPS) produces both systemic and pulmonary inflammatory responses. The aim of this study was to further characterize the response to LPS in order to develop a human model suitable for early testing of drug candidates developed for the treatment for chronic obstructive pulmonary disease (COPD). Materials: Blood and induced sputum were obtained 4, 24 and 48 h fo

The risk of contralateral breast cancer in daughters of women with and without breast cancer.

We aimed to estimate the 15-year and lifetime risks of contralateral breast cancer in breast cancer patients according to the age of diagnosis of the first cancer and the history of breast cancer in the mother. The risks of contralateral breast cancer were estimated for all 78,775 breast cancer patients in the Swedish Family-Cancer Database (age at diagnosis of first breast cancer

Are intravenous injections of contrast media really less nephrotoxic than intra-arterial injections?

We oppose the opinion that the intra-arterial administration of iodine-based contrast media (CM) appears to pose a greater risk of contrast medium-induced nephropathy (CIN) than intravenous administration since 1) in intra-arterial coronary procedures and most other intra-arterial angiographic examinations, CM injections are also intravenous relative to the kidneys, 2) there is a lack of comparati

Distribution of vasoactive intestinal peptide, pituitary adenylate cyclase-activating peptide, nitric oxide synthase, and their receptors in human and rat sphenopalatine ganglion.

Cranial parasympathetic outflow is mediated through the sphenopalatine ganglion (SPG). The present study was performed to examine the expression of the parasympathetic signaling transmitters and their receptors in human and rat SPG. Indirect immunofluorescence technique was used for the demonstration of vasoactive intestinal peptide (VIP), pituitary adenylate cyclase-activating peptide (PACAP), ni

The immune diversity in a test tube - Non-immunised antibody libraries and functional variability in defined protein scaffolds

Technologies to develop and evolve the function of proteins and, in particular, antibodies have developed rapidly since the introduction of phage display. Importantly, it has become possible to identify molecules with binding properties that cannot be found by other means. A range of different approaches to create general libraries that are useful for the selection of such molecules specific for e

Case history discourse. A rhetoric of troublesome youngsters and faceless treatment

In numerous social control settings, staff routinely write case histories on clients to assist colleagues and authorities in treatment decisions. In this article, we examine how such institutional writing constructs ‘working versions’ of youngsters, portraying their objects of care as personally troublesome. Simultaneously, the institution is portrayed as facelessly, uniformly and collectively rem

Effects of oat bran, processed to different molecular weights of beta-glucan, on plasma lipids and caecal formation of SCFA in mice.

In the present study, we evaluated the cholesterol-lowering effects of different oat bran (OB) preparations, differing regarding their peak molecular weight (MWp) of beta-glucans (2348, 1311, 241, 56, 21 or < 10 kDa), in C57BL/6NCrl mice. The diets were designed to be atherogenic (0.8 % cholesterol and 0.1 % cholic acid), and they reflected the Western diet pattern (41 % energy fat). All OB prepar

Adhesive Mechanisms of Histone-Induced Neutrophil-Endothelium Interactions in the Muscle Microcirculation.

Extracellular histones released during cell damage have the capacity to cause tissue injury associated with increased leukocyte accumulation. However, the molecular mechanisms regulating histone-induced leukocyte recruitment remain elusive. The objective of this study was to examine the role of adhesion molecules in histone-dependent leukocyte accumulation by use of intravital microscopy of the mo

Projected changes in terrestrial carbon storage in Europe under climate and land use change, 1990-2100

Changes in climate and land use, caused by socio-economic changes, greenhouse gas emissions, agricultural policies and other factors, are known to affect both natural and managed ecosystems, and will likely impact on the European terrestrial carbon balance during the coming decades. This study presents a comprehensive European Union wide (EU15 plus Norway and Switzerland, EU*) assessment of potent

ALMA, a new tool for the management of asthma patients in clinical practice: development, validation and initial clinical findings.

BACKGROUND: Several instruments have been developed for measuring asthma control, but there is still a need to provide a structure for primary care asthma reviews. AIMS: The Active Life with Asthma (ALMA) tool was developed with the aim of structuring patient visits and assessing asthma treatment in primary care. The ability of ALMA to map out the care of asthma patients was evaluated and validate

Covarying Hydroclimate Patterns between Monsoonal Asia and North America over the Past 600 Years

Proxy data with large spatial coverage spanning to the preindustrial era not only provide invaluable material to investigate hydroclimate changes in different regions but also enable studies on temporal changes in the teleconnections between these regions. Applying the singular value decomposition (SVD) method to tree-ring-based field reconstructions of the Palmer drought severity index (PDSI) ove

Occupational allergic contact dermatitis caused by sterile non-latex protective gloves: clinical investigation and chemical analyses.

Background An increased frequency of occupational contact hand dermatitis among surgical operating theatre personnel has been noticed. Objectives To evaluate patients with occupational contact dermatitis caused by their rubber gloves, and to describe a method for analysing the content of the allergens in the gloves. Materials and methods Patch tests were performed with the baseline series, a rubbe
