The stressed vascular barrier and coagulation - The impact of key glycocalyx components on in vitro clot formation.

Introduction: A functional vascular barrier controlling leukocyte recruitment into the perivascular space relies on an intact endothelial glycocalyx (EGX). Critical disease states such as sepsis or trauma can induce massive shedding of EGX components into the blood stream. Previous studies have shown that high blood levels of EGX components are correlated with bleeding in patients.

A Photo-Crosslinkable Biotin Derivative of the Phosphoantigen (E)-4-Hydroxy-3-Methylbut-2-Enyl Diphosphate (HMBPP) Activates Vγ9Vδ2 T Cells and Binds to the HMBPP Site of BTN3A1.

Vγ9Vδ2 T cells play an important role in the cross talk of the innate and adaptive immune system. For their activation by phosphoantigens (PAgs), both cell surface receptors, the eponymous Vγ9Vδ2 T cell antigen receptors (Vγ9Vδ2 TCRs) on Vγ9Vδ2 T cells and butyrophilin 3A1 (BTN3A1) on the phosphoantigen-"presenting" cell, are mandatory. To find yet undetected but further contributing proteins, a biotinylated, photo-crosslinkable benzophenone probe BioBP-HMBPP (2) was synthesized from a known allyl alcohol in nine steps and overall 16 % yield.

The Cytoprotective Effects of E-α-(4-Methoxyphenyl)-2',3,4,4'-Tetramethoxychalcone (E-α-p-OMe-C6H4-TMC)--A Novel and Non-Cytotoxic HO-1 Inducer.

Cell protection against different noxious stimuli like oxidative stress or chemical toxins plays a central role in the treatment of many diseases. The inducible heme oxygenase isoform, heme oxygenase-1 (HO-1), is known to protect cells against a variety of harmful conditions including apoptosis. Because a number of medium strong electrophiles from a series of α-X-substituted 2',3,4,4'-tetramethoxychalcones (α-X-TMCs, X = H, F, Cl, Br, I, CN, Me, p-NO2-C6H4, Ph, p-OMe-C6H4, NO2, CF3, COOEt, COOH) had proven to activate Nrf2 resulting in HO-1 induction and inhibit NF-κB downstream target genes, their protective effect against staurosporine induced apoptosis and reactive oxygen species (ROS) production was investigated.

[Food composition and results of dietetic intervention in patients with hypercholesterolemia in a Tyrolean village. Tyrolean heart project of Oberperfuss].

In the course of a field survey of coronary risk factors carried out in the Tyrolean village of Oberperfuss, a 24-hour food recall form was filled in by all inhabitants aged between 20 and 64 years. The food composition is presented. The dietary intervention programme for people with hypercholesterolaemia resulted in a 19.
