Recently the generally accepted roles of protein-bound zinc in catalysis and structure stabilization were complemented by regulatory functions. An important question with respect to a regulatory function, however, concerns the controversially discussed concentration of free zinc ions in different physiological environments. If the transduction of a zinc signal is mediated by binding of zinc ion...

background: there have been very few studies, with contradictory results, on the zinc status of children and adolescents with type-1 diabetes mellitus. the objective of this cross-sectional study was to determine zinc status based on the serum zinc concentration in type-1 diabetic children and adolescents and compare it with that of healthy controls. methods: thirty children and adolescents wit...

Introduction There are several reports of zinc deficiency in pathogenesis of acute and chronic diarrhea. The literature review showed children with diarrhea and chronic gastroduodenitis performed zinc deficiency in majority of cases (1). The normal values of zinc in blood serum are 12.8-27.8 μmol/l (2). There is a threshold of 13μmol/l zinc concentration for zinc deficiency diagnosis. The zinc ...

a b s t r a c t   zinc deficiency in man is characterized by skin lesion, alopecia and has been linked to growth retardation and mental disturbance. for supplementation purposes zinc is currently presented as its sulfate salt, from which uptake by the body is poor, necesseting the administration of high doses. this leads to a range of unpleasant side effects. in order to increase the bioavailab...

effect of concentration parameters on recovery of zinc oxidized minerals from lead flotation tailings of dandy mineral processing plant in north-western iran was studied. a sulfidization-flotation method has been used on a laboratory scale to investigate the effect of various reagents such as sodium sulfide as sulfidizing agent, primary amine as collector, dispersants and flocculants with diffe...

OBJECTIVE To determine the inhibition effect of zinc sulfate on isolates of enteric bacteria. MATERIALS AND METHODS Mueller-Hinton agar containing different concentrations of zinc sulfate was prepared. Isolates used in this study were obtained from local clinics. They were Salmonella typhi, Salmonella groups A, B, C, D and E, Escherichia coli, Enterobacter, Shigella and Vibrio cholerae. Overn...
