A role for metallothionein in intestinal zinc absorption has been the subject of considerable debate. If metallothionein affects zinc absorption, then those factors that induce metallothionein synthesis (e.g., heavy metals, hormones) should alter zinc absorption and homeostasis. The present studies used metallothionein transgenic mice (overexpressing) and metallothionein knockout mice (no expre...

this study was conducted for evaluating the combined effect of soil moisture, phosphorus (p) and zinc (zn) levels on the growth attributes of potato (solanum tuberosum l. cv. agria). this investigation was arranged as a factorial experiment based on randomized complete blocks design with zn at three levels (0, 10 and 20mg zn per kg dry soil as zinc sulfate), p at three levels (0, 30 and 60mg pe...

Resolving the mechanisms underlying the temporal and spatial profile of zinc transporter expression in response to zinc availability is key to understanding zinc homeostasis. The mRNA expression of seven zinc transporters was studied in zebrafish gills when treated with zinc deficiency/excess over a 14-day period. Of these, ZnT1, ZnT5, ZIP3, and ZIP10 were differentially expressed in response t...

Introduction: Zinc deficiency is a health problem in many communities, especially among children because of growth spurt. Zinc deficiency can causegrowth limitation, delay in sexuel maturity, behavior disorders and abnormalities of immune system,susceptibility to respiratory and gasterointestinal infections and impairment of taste and smell perception. Material and Method: One of the methods ...

introduction: ferric sulfate pulpotomy is a safe and effective method of the pulpotomy of primary teeth. but the results of different studies indicate low success rate of ferric sulfate pulpotomy in comparison to formocresol pulpotomy and a portion of these failures may be related to stimulating and harmful effects of zinc oxide eugenol paste. the aim of this study was to determine and compare ...

The effects of dietary zinc on zinc absorption and excretion were evaluated with six 12-week-old beagles. The dogs were fed a commercial dry food later supplemented with 2 and 4mg/kg of body weight per day of either zinc sulphate, zinc acetate or zinc oxide. The concentrations of zinc in the urine and faeces of all treatment groups were increased depending on the type of zinc salts and the dosa...

Zinc is essential for many cellular processes. To use Caenorhabditis elegans to study zinc metabolism, we developed culture conditions allowing full control of dietary zinc and methods to measure zinc content of animals. Dietary zinc dramatically affected growth and zinc content; wild-type worms survived from 7 microm to 1.3 mm dietary zinc, and zinc content varied 27-fold. We investigated cdf-...
