Previous studies of the yeast Saccharomyces cerevisiae indicated that the vacuole is a major site of zinc storage in the cell. However, these studies did not address the absolute level of zinc that was stored in the vacuole nor did they examine the abundances of stored zinc in other compartments of the cell. In this report, we describe an analysis of the cellular distribution of zinc by use of ...
BACKGROUND Food acidulants, β-carotene-rich vegetables and sulfur compound-rich Allium spices are known to improve zinc bioaccessibility from food grains. This animal study evaluated the positive influence of these promoters of zinc bioaccessibility on zinc status during zinc repletion in Wistar rats previously rendered zinc-deficient by feeding a zinc-deficient semi-synthetic diet for 4 weeks....
Zinc is essential for multiple aspects of metabolism. Physiologic signs of zinc depletion are linked with diverse biochemical functions rather than with a specific function, which makes it difficult to identify biomarkers of zinc nutrition. Nutrients, such as zinc, that are required for general metabolism are called type 2 nutrients. Protein and magnesium are examples of other type 2 nutrients....
Many excitatory synapses contain high levels of mobile zinc within glutamatergic vesicles. Although synaptic zinc and glutamate are coreleased, it is controversial whether zinc diffuses away from the release site or whether it remains bound to presynaptic membranes or proteins after its release. To study zinc transmission and quantify zinc levels, we required a high-affinity rapid zinc chelator...
OBJECTIVE Zinc deficiency is a problem world-wide. Zinc and insulin are intimately related, and a reduced zinc intake may affect glucose metabolism. The present study investigates how subclinical zinc deficiency in rats affects glucose metabolism and zinc distribution in the pancreas. METHODS Glucose metabolism was evaluated by blood-glucose, serum insulin, homeostasis model assessment (HOMA)...
in order to evaluate the efficiency of inoculation of chickpea seeds with mesorhizobium and application of nitrogen and zinc on yield and yield components of rainfed chickpea an experiment was carried out in research station of shirvan-chardavel, ilam. the experiment was conducted in randomized complete block design (rcbd) with six treatments including mesorhizobium inoculation, nitrogen (40 kg...
The role of zinc deficiency as an important cause of morbidity and impaired linear growth has prompted the need to identify indicators of population zinc status. Three indicators have been recommended - prevalence of zinc intakes below the estimated average requirement (EAR), percentage with low serum zinc concentrations, and percentage of children aged < 5 years who are stunted. This review ou...
Zinc is the second most abundant metal in human body, and a relatively large amount of zinc is found in the brain, indicating its essential role in central nerve system. Zn 2+ is stored in synaptic vesicles of glutamatergic neurons and is released from the terminals for synaptic signaling. Zinc is also found in zinc containing proteins. It is estimated that the human proteome contains about 300...

BACKGROUND AND OBJECTIVES This study was conducted to evaluate plasma levels of zinc in children with celiac disease, to correlate plasma zinc levels among the celiacs with short stature and diarrhea and to compare plasma zinc levels in deficient patients on gluten-free diet (GFD) with or without 4 weeks of zinc supplementation. METHODS A total of 134 patients underwent plasma zinc estimation...
