Background: Since cellular membranes play key role in the physiological pathways of the cell, such as fertilization through almost every cellular function to cell division, it is very important to assess the structural and functional activity of the sperm membrane. In this study, a new method for measurement of sperm membrane stability measured the amount of zinc which liberated after being exp...

Anthrax lethal factor (LF) is a zinc-dependent endopeptidase which, through a process facilitated by protective antigen, translocates to the host cell cytosol in a partially unfolded state. In the current report, the influence of urea and guanidine hydrochloride (GdnHCl) on LF׳s catalytic function, fold and metal binding was assessed at neutral pH. Both urea and GdnHCl were found to inhibit LF ...

abstract   objective: to determine the effect of oral zinc sulfate supplementation given with coamoxiclav when compared with coamoxiclav alone for treatment of otitis media with effusion (ome). the efficacy of the drug was assessed 3 and 6 weeks after administration .   methods: in a double-blind, randomized trial 4 to 14 years old children with ome who referred to ear, nose and throat clinic, ...

BACKGROUND AND OBJECTIVES Protein-bound solutes are poorly cleared by peritoneal dialysis. We examined the hypothesis that plasma concentrations of bound solutes would therefore rise as residual renal function is lost. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Clearances of urea indican and p-cresol sulfate were measured in peritoneal dialysis patients with and without residual function. ...

POWERS J. B. AND S. S. WlNANS. Sexual behavior in peripherally anosmic male hamsters. PHYSIOL. BEHAV 10(2) 361 368, 1973.-Sexually experienced and inexperienced male hamsters mated normally after they had been rendered temporarily anosmic by intranasal zinc sulfate treatment (Experiment 1), in contrast to the complete absence of sexual behavior following removal of the olfactory bulbs. The effi...

The influence of magnetic field on some kinetic crystallization parameters of the systems zinc sulfate – water and copper sulfate – water were investigated in a series of controlled batch cooling experiments. The solutions were exposed to magnetic fields with different intensities, up to a maximum of 0.7 T. A clear influence of magnetic field on the zinc sulfate crystallization parameters was f...

introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...

objective: the present study was performed to compare the antioxidant effect of two different doses of zinc on lipid oxidation in type 2 diabetic patients. materials and methods: this double-blind, randomized controlled trial was conducted on 60 type 2 diabetic patients in yazd diabetes research center in 2008. the subjects were randomly allocated to receive zinc sulfate (iran, alhavi) either 2...
