Abstract

The program QTHIN combines those methods for processing energy-dispersive X-ray spectra and computing concentrations best suited to thin section microanalysis in TEM or STEM. The program is in BASIC, and so can be modified (for instance for unusual geometries, other matrices such as oxides, etc.). It is suitable for routine use on complex samples with peak overlaps, and for "not-so-thin" samples in which absorption is not negligible.

Molecular orbital study on the glutathione-dependent detoxication of ozonides.

The present paper describes a theoretical study on the mechanism underlying the reaction of cellular glutathione (GSH) with polyunsaturated fatty acid ozonides. The reaction can be catalyzed by glutathione S-transferases and leads to detoxication of the ozonides. Semi-empirical molecular orbital computer calculations suggest that the reaction of glutathione with ozonides involves a nucleophilic attack at one of the carbon atoms of the ozonide ring, instead of at one of the peroxidic oxygen atoms of the ozonide ring. This implies a mechanism different from that of the glutathione S-transferase-mediated reaction with hydroperoxides, previously proposed for the glutathione-dependent detoxication of fatty acid ozonides.
