Intrauterine growth restriction.

Pathophysiological processes underlying intrauterine growth restriction are very complex and poorly understood. Growth restricted fetuses are at risk of hypoxia and, therefore, an early diagnosis of intrauterine growth restriction is important for initiation of fetal surveillance. Application of a three-dimensional ultrasound method for estimation of fetal weight promises better precision. Use of

Ximelagatran vs warfarin for stroke prevention in patients with nonvalvular atrial fibrillation - A Randomized trial

Context Inpatients with nonvalvular atrial fibrillation, warfarin prevents ischemic stroke, but dose adjustment, coagulation monitoring, and bleeding limit its use. Objective To compare the efficacy of the oral direct thrombin inhibitor ximelagatran with warfarin for prevention of stroke and systemic embolism. Design, Setting, and Participants Double-blind, randomized, multicenter trial (20002001)

Cleavage of cartilage oligomeric matrix protein (thrombospondin-5) by matrix metalloproteinases and a disintegrin and metalloproteinase with thrombospondin motifs

Cartilage oligomeric matrix protein (COMP) is a pentameric glycoprotein present in cartilage, tendon and ligament. Fragments of the molecule are present in the diseased cartilage, synovial fluid and serum of patients with knee injuries, osteoarthritis and rheumatoid arthritis. Although COMP is a substrate for several matrix metalloprotemases (MMPs), the enzymes responsible for COMP degradation in

Lymphocyte CC chemokine receptor 9 and epithelial thymus-expressed chemokine (TECK) expression distinguish the small intestinal immune compartment: Epithelial expression of tissue-specific chemokines as an organizing principle in regional immunity

The immune system has evolved specialized cellular and molecular mechanisms for targeting and regulating immune responses at epithelial surfaces. Here we show that small intestinal intraepithelial lymphocytes and lamina propria lymphocytes migrate to thymus-expressed chemokine (TECK). This attraction is mediated by CC chemokine receptor (CCR)9, a chemoattractant receptor expressed at high levels b
