Zinc was electrodeposited from an acidic sulphate solution on commercial steel sheet substrates galvanostatically at 10, 20, and 100 mA/cm2. The steel substrates had an average roughness number of 1.34 microns and a high percentage of its grains had their (111) planes parallel to the plate surface. During electrodeposition at 10 mA/cm2, on some specimens, there was an intense potential fluctuat...
Micromolar zinc potentiates neuronal nicotinic acetylcholine receptors (nAChRs) in a subtype-dependent manner. Zinc potentiates receptor function even at saturating agonist concentrations, without altering the receptor desensitization rate. Potentiation could occur through an increase in the number of available receptors, an increase in single-channel current amplitude, or an increase in single...
Zinc has important effects on structural and functional activities of many proteins and enzymes involved in biological activities specially regulation of immune system. Deficiencies of this element may result in many disease and immunological disorders. This study was carried out to examine the in vitro effects of differen...
Maternal zinc deficiency during pregnancy results in a high frequency of fetal eye malformations in the Long-Evans rat. In this study we examine the development of the eye from days 12 through 21 of gestation in conceptuses of dams fed deficient or adequate levels of zinc and also examine maternal plasma and conceptus zinc concentrations during this period. Dams were fed diets containing 0.5 (0...
Objective: The aim of this study was to evaluate the effect of zinc and magnesium supplementation on glycemic control and serum insulin in type 2 diabetic patients. Materials and Methods: In this randomized clinical trial 70 diabetic patients who referred to Yazd Diabetes Center were selected. Subjects received 500 mg/day magnesium oxide or 100 mg/day zinc sulfate randomly for 8 weeks. At th...
A greenhouse experiment was conducted in factorial experiment arranged as a completely randomized design (CRD) to evaluate the role of tree indigenous arbuscular mycorrhizal fungi (AMF) species originated from a polluted soil in phytoremediation of zinc polluted soils using maize as a host plant. The experiment consisted of plants inoculated with AMF (G1(Glomus intraradices), G2(Glomus mosseae...
The effects of ZnCl2 on [3H]GABA binding to GABAA and GABAA binding sites were investigated using receptor autoradiography. At concentrations exceeding 100 microM, zinc non-competitively inhibited GABAB binding in a dose dependent fashion. GABAA binding was not inhibited significantly by zinc eliminating the possibility of a non-specific effect of zinc. Increased calcium concentrations up to 10...
Introduction: Since the existing methods to remove the hazardous material are associated with problems, recently, the tendency is to use Biosorption methods by Low-cost adsorbents: this was investigated in our project. This study was conducted to investigate the adsorption of lead and zinc from aqueous solution by using powdered excess sludge (biosolid) from sludge drying beds of municipal wast...
in order to investigate lentil response to application times and amounts of zinc, an experiment was arranged as factorial based on randomized complete block design with four replications on farm research of gonbad higher education center during 2008-2009. treatments were application times (before flowering and beginning of pod setting) and application rates (0, 0.5, 1, 1.5 and 2 liter per hecta...
