Reactive oxygen (ROS) and nitrogen oxide (RNOS) species are produced as by-products of oxidative metabolism. A major function for ROS and RNOS is immunological host defense. Recent evidence indicate that ROS and RNOS may also function as signaling molecules. However, high levels of ROS and RNOS have been considered to potentially damage cellular macromolecules and have been implicated in the pa...

studies with dibutyl~hloro[~H]methyltin chloride have shown that it co-migrates with subunit 9, both in its monomeric form (mol.wt. 7000-8000) and its aggregated (hexameric) form (mol.wt. 45000). Studies with yeast mitochondria and the purified ATP synthase indicate that the ATP synthase contains approx. six binding sites for triethyltin and an equivalent number for dibutylchloromethyltin chlor...

The combination of the ionic liquid co-lyophilized lipase and microwave irradiation was used to improve enzyme performance in enantioselective esterification of α-lipoic acid. Effects of various reaction conditions on enzyme activity and enantioselectivity were investigated. Under optimal condition, the highest enantioselectivity (E = 41.2) was observed with a high enzyme activity (178.1 μmol/h...

objective(s): to investigate the effect of topical administration of alpha-lipoic acid into chitosan conduit on peripheral nerve regeneration using a rat sciatic nerve transection model. materials and methods: forty five wistar rats were divided into three experimental groups randomly. a 10-mm gap of sciatic nerve was bridged with a chitosan conduit following surgical preparation and anesthesia...

The detection of bacterial lipoic acid by a modified g.c.-m.s. procedure is reported. Cells were hydrolysed in HCl to release protein-bound lipoic acid, which, after extraction into benzene, was reduced with NaBH4. The dihydrolipic acid so generated was then isolated by covalent chromatography on dithiolspecific p-aminophenylarsenoxide-agarose and, after elution by 2,3-dimercaptopropane-1-sulph...

Diese Dissertation wurde selbständig, ohne unerlaubte Hilfe erarbeitet. 1. Overview and aim of this study Ischemia reperfusion injury (IRI) is a serious clinical problem during liver resections, liver transplantation, and haemorrhagic shock. The pathomechanisms of this injury can be divided into incidents during ischemia and events occuring during reperfusion. Some main pathophysiologic feature...

We investigated the potential of natural occurring antioxidant alpha-lipoic acid to prevent hypertension and hypertensive tissue injury induced by deoxycorticosterone acetate (DOCA) and salt in rats. Two weeks after the start of DOCA-salt treatment, the rats were given alpha-lipoic acid (10 or 100 mg/kg/day, s.c.) or its vehicle for 2 weeks. Uninephrectomized rats without DOCA-salt treatment se...
