Neutralization by Metal Ions of the Toxicity of Sodium Selenide
Inert metal-selenide colloids are found in animals. They are believed to afford cross-protection against the toxicities of both metals and selenocompounds. Here, the toxicities of metal salt and sodium selenide mixtures were systematically studied using the death rate of Saccharomyces cerevisiae cells as an indicator. In parallel, the abilities of these mixtures to produce colloids were assesse...
متن کاملSodium Selenide Toxicity Is Mediated by O2-Dependent DNA Breaks
Hydrogen selenide is a recurrent metabolite of selenium compounds. However, few experiments studied the direct link between this toxic agent and cell death. To address this question, we first screened a systematic collection of Saccharomyces cerevisiae haploid knockout strains for sensitivity to sodium selenide, a donor for hydrogen selenide (H(2)Se/HSe(-/)Se(2-)). Among the genes whose deletio...
متن کاملEffect of Sodium Selenide on Renal Toxicity Induced By Mercuric Chloride in Rat
Background and Aims: Mercury, with its oxidative activity, causes damage to the antioxidant enzymes thus resulting in physiological disorders. Sodium selenide is an antioxidant that protects antioxidant enzymes. The aim of this study was to investigate the protective effect of sodium selenide on renal toxicity induced by mercuric chloride in rats. Materials and Methods: Animals were divided in...
متن کاملZinc selenide optical fibers.
200 μm MRSEC researchers have fabricated the first optical Fibers made from zinc selenide, using a high-pressure Chemical deposition technique invented in the MRSEC. Optical fibers are a cornerstone of modern science and technology, yet remain fundamentally limited by the types of materials from which they can be made. With these new ZnSe fibers, it is now possible to exploit the materials prop...
متن کاملBis(4-nitrophenyl) selenide
In the title compound, C12H8N2O4Se, the Se atom is situated on a twofold rotational axis, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, the C-Se-C angle is 99.48 (13)°, the two benzene rings are inclined to each other at an angle of 63.8 (1)° and the nitro group is twisted by 15.9 (1)° from the attached benzene ring. In the crystal, mol-ecules are held together through w...
