Thioltransferase, also known as glutaredoxin, is an enzyme that catalyzes the reduction of a variety of disulfide compounds. In Schizosaccharomyces pombe, two thioltransferases were reported and the cDNA of one of the thioltransferases (thioltransferase-1) was cloned. Using a Northern blot assay, we investigated the thioltransferase transcription in response to various stress conditions. When t...

Zinc chloride solution injected into the testes of 49 Syrian hamsters during the early spring months resulted in two embryonal carcinomas of the testis found at necropsy 10 weeks later. The zinc chloride injections were made during the period of rapid seasonal gonadal growth when spermatogonial division is activated and resulted in areas of coagulative necrosis occupying about 25% of each testi...

To research the relationship of micro-structures and antibacterial properties of the titanium-doped ZnO powders and probe their antibacterial mechanism, titanium-doped ZnO powders with different shapes and sizes were prepared from different zinc salts by alcohothermal method. The ZnO powders were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), u...

Introduction: Formaldehyde is one of the most common chemicals used for embalming and as a result teaching anatomy. Because of the adverse effects of formaldehyde on human health and also its environmental complications, this study was conducted to investigate a new solution containing zinc chloride for fixation and preservation of anatomical specimens.  Methods: In this study, we used 40...

A series of geometry, frequency, and energy calculations of chloroaquazinc(II) complexes were carried out at up to the MP2/6-31+G* level. A thorough examination of all species up to and including hexacoordinate species, and with up to six chlorides, was carried out. The structures of the complexes are compared with experimental data where available. The solution chemistry of zinc(II) in the pre...

The objective of this study was to evaluate the effect of heavy metals, at environmentally relevant concentrations, on the immune response of rainbow trout. Trout were exposed for 30 d to cadmium chloride (CdCl2), mercuric chloride (HgCl2), or zinc chloride (ZnCl2) either individually or in combinations: CdCl2/HgCl2, CdCl2/ZnCl2, HgCl2/ZnCl2, or CdCl2/HgCl2/ZnCl2. Following the 30-d exposure, p...

The rates of zinc chloride (Lewis acid) catalysed oxidation of thioanisole and several para-substituted thioanisoles by permanganate have been studied in anhydrous acetone solutions. The kinetic rate law obtained indicates that a complex between permanganate and the Lewis acid (ZnCl2) is formed before oxidation of the sulfur-containing compounds occurs. The function of the zinc chloride is to e...

The rates and mechanism of zinc chloride (Lewis acid) catalysed oxidation of several organic sulfoxides by permanganate have been studied in anhydrous acetone solutions. The kinetic rate law obtained indicates that a complex between permanganate and the Lewis acid (ZnCl2) is formed before oxidation of the sulfoxides occurs. The function of the zinc chloride is to enhance the reactivity of perma...

A comparative analysis of a magnesium-zinc stabilizer based on pentaerythritol and standard calcium-zinc stearic acid was carried out. The influence the ratio magnesium (PenMg) to zinc (PenZn) thermal thermo-mechanical stability polyvinyl chloride (PVC) is considered.
