BACKGROUND During clinical trials bosentan, the first orally active endothelin receptor antagonist, caused asymptomatic transaminase elevations in some patients. In this study we investigated whether inhibition of the hepatocanalicular bile salt export pump (rodents, Bsep; humans, BSEP ABCB11) could account for bosentan-induced liver injury. METHODS We(More)
Compared to the overall multiplicity of more than 20 plant Hsfs, detailed analyses are mainly restricted to tomato and Arabidopsis and to three important representatives of the family (Hsfs A1, A2 and B1). The three Hsfs represent examples of striking functional diversification specialized for the three phases of the heat stress (hs) response (triggering,(More)
Similar to the situation in mammalian cells and yeast, messenger ribonucleo protein (mRNP) homeostasis in plant cells depends on rapid transitions between three functional states, i.e. translated mRNPs in polysomes, stored mRNPs and mRNPs under degradation. Studies in mammalian cells showed that whenever the dynamic exchange of the components between these(More)
Entamoeba histolytica is an intestinal parasite and the causative agent of amoebiasis, which is a significant source of morbidity and mortality in developing countries. Here we present the genome of E. histolytica, which reveals a variety of metabolic adaptations shared with two other amitochondrial protist pathogens: Giardia lamblia and Trichomonas(More)
Coronary artery disease (CAD) arising from atherosclerosis is a leading cause of death and morbidity worldwide. The underlying pathogenesis involves an imbalanced lipid metabolism and a maladaptive immune response entailing a chronic inflammation of the arterial wall. The disturbed equilibrium of lipid accumulation, immune responses and their clearance is(More)
Bone marrow and peripheral blood of adults contain a special sub-type of progenitor cells which are able to differentiate into mature endothelial cells, thus contributing to re-endothelialization and neo-vascularization. These angiogenic cells have properties of embryonal angioblasts and were termed endothelial progenitor cells (EPCs). In general, three(More)
Apoptosis is a pivotal process in embryogenesis and postnatal cell homeostasis and involves the shedding of membranous microvesicles termed apoptotic bodies. In response to tissue damage, the CXC chemokine CXCL12 and its receptor CXCR4 counteract apoptosis and recruit progenitor cells. Here, we show that endothelial cell-derived apoptotic bodies are(More)
INTRODUCTION The current investigation aimed to study the efficacy of hemostatic therapy guided either by conventional coagulation analyses or point-of-care (POC) testing in coagulopathic cardiac surgery patients. METHODS Patients undergoing complex cardiac surgery were assessed for eligibility. Those patients in whom diffuse bleeding was diagnosed after(More)
Inflammatory recruitment of leukocytes is governed by dynamic interactions between integrins and endothelial immunoglobulin superfamily (IgSF) proteins. We have identified the IgSF member junctional adhesion molecule 1 (JAM-1) as a ligand of the beta(2) integrin lymphocyte function-associated antigen 1 (LFA-1). Under static and physiological flow(More)
Circulating endothelial progenitor cells (EPCs) may contribute to endothelial regeneration; however, the exact mechanisms of their arterial homing remain elusive. We examined the role of the angiogenic chemokine receptor CXCR2 in the homing of human EPCs. Isolated EPCs expressed CXCR2 together with kinase insert domain-containing receptor, CD31, vascular(More)
