To establish the association between prior knee pain consultations and early diagnosis of knee osteoarthritis (OA) by weighted cumulative exposure (WCE) models.

This study, carried out in a work rehabilitation unit in Sweden, investigated how clients perceived their work experiences after a one-year follow up. A semi-structured interview was administered to 14 former clients and a content analysis was applied. Seven categories were derived from the results: 'Expectations of the rehabilitation process'; 'Social relationships'; 'Client influences on the reh

Anaerobic bacteria dominate the human normal microbiota but strikingly little is known about these commensals. Finegoldia magna is a Gram-positive anaerobe found in the skin and at other non-sterile body surfaces, but it is also an opportunistic pathogen. This study describes a novel protein designated FAF (F. magnaAdhesion Factor) and expressed by more than ninety percent of F. magna isolates. Th

OBJECTIVE: The visual system is vital during critical activities such as driving. Studying how alcohol compromises the visual system physiologically is therefore important for safety reasons. The objective of the study was to investigate alcohol-related impairments in visual tasks performed under controlled breath alcohol concentrations (BAC) to determine dose-dependent effects. METHODS: Alcohol's

PURPOSE: To investigate the transport of Gd-DTPA(2-) in different layers of femoral knee cartilage in vivo. MATERIALS AND METHODS: T(1) measurements (1.5 Tesla) were performed in femoral knee cartilage of 23 healthy volunteers. The weight-bearing central cartilage was analyzed before contrast and at eight time points after an intravenous injection of Gd-DTPA(2-) : 12-60 min (4 volunteers) and 1-4

Mutations in the gene encoding for a de novo methyltransferase, DNMT3B, lead to an autosomal recessive Immunodeficiency, Centromeric instability and Facial anomalies (ICF) syndrome. To analyse the protein structure and consequences of ICF-causing mutations, we modelled the structure of the DNMT3B methyltransferase domain based on Haemophilus haemolyticus protein in complex with the cofactor AdoMet

Although the triptan drugs provide effective relief from migraine for many patients, a substantial number of affected individuals are unresponsive to these compounds, and such therapy can also lead to a range of adverse effects. Telcagepant represents a new class of antimigraine drug-the calcitonin gene-related peptide receptor blockers. This compound exerts its effects by blocking receptors for t

Histamine in the rat stomach resides in enterochromaffin-like (ECL) cells and mast cells. The ECL cells are peptide-hormone-producing endocrine cells known to release histamine and chromogranin-A-derived peptides (such as pancreastatin) in response to gastrin. Ischemia (induced by clamping of the celiac artery or by gastric submucosal microinfusion of the vasoconstrictor endothelin) mobilizes larg

PURPOSE OF REVIEW: Family history of bladder cancer is a known risk factor for bladder cancer but new data have emerged on the influence of a family history of other tumours than bladder cancer. Recent data have shown that family history influences survival of bladder cancer. Gene identification has been successful particularly on low-risk genes influencing susceptibility and prognosis. RECENT FIN

Formaldehyde is a well-known contact sensitizer. Formaldehyde releasers are widely used preservatives in cosmetics.

Objective: To study the effects of different doses of platelet activating factor receptor antagonist WEB 2170 on animal survival, haemodynamics, reperfusion and ultrastructural changes in the ischaemic liver in rats undergoing 90-min total hepatic inflow interruption (THII). Design: Sixty-five rats were divided into five groups. All animals underwent 90-min THII. Group 1 served as controls. Group

Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare soft tissue tumor of intermediate malignancy and uncertain cellular origin and lineage of differentiation. Although PHAT is still poorly characterized at the genetic level, there is a potential genetic overlap with two other soft tissue tumors: myxoinflammatory fibroblastic sarcoma (MIFS) and hemosiderotic fibrolipomatous tumor (HFLT); MIF

Despite intense efforts to develop radiotracers to detect cancers or monitor treatment response, few are widely used as a result of challenges with demonstrating clear clinical use. We reasoned that a radiotracer targeting a validated clinical biomarker could more clearly assess the advantages of imaging cancer. The virtues and shortcomings of measuring secreted prostate-specific antigen (PSA), an
