The essential element zinc plays critical roles in biology. High zinc homeostasis mechanisms are beginning to be defined in animals, but low zinc homeostasis is poorly characterized. We investigated low zinc homeostasis in Caenorhabditis elegans because the genome encodes 14 evolutionarily conserved Zrt, Irt-like protein (ZIP) zinc transporter family members. Three C. elegans zipt genes were re...

Zinc is essential micronutrients for proteins production in plants; also zinc is main composition of ribosome and is essential for their development. Zinc is active element in biochemical processes and has a chemical and biological interaction with some other elements. Phosphorus is the most important element which interferes on zinc uptake by plants. Phosphorus is the important element that in...

The primary objective of the current study was the investigation of the influence of zinc asparaginate supplementation for 7 and 14 days on toxic metal and metalloid content in rat organs and tissues. Rats obtained zinc asparaginate in doses of 5 and 15 mg/kg/day for 7 and 14 days. At the end of the experiment rat tissues and organs (liver, kidney, heart, m. gastrocnemius, serum, and hair) were...

introduction: zinc has been known as an essential trace element in human, animal and plant nutrition. during pregnancy, the daily requirement increases to 25% and its serum level decreases. the serum level of zinc in adults is arranged from 80 to 150 μg/dl. considering the importance of this trace element and its role during pregnancy, this study was conducted on pregnant women in the community...

Zinc is a trace element that is essential for innate and adaptive immune responses. In addition to being a structural element of many proteins, zinc also functions as a neurotransmitter and an intracellular messenger. Temporal or spatial changes in bioavailable zinc may influence the activity of several enzymes, including kinases and phosphatases. We provide evidence that zinc functions as an i...

Zinc transporters are solute carrier family members. To date, 10 zinc transporters (ZnTs) and 14 Zrt-, Irt-like proteins (ZIPs) have been identified. ZnTs control intracellular zinc levels by effluxing zinc from the cytoplasm into the extracellular fluid, intracellular vesicles, and organelles; ZIPs also contribute to control intracellular zinc levels with influxing zinc into the cytoplasm. Rec...

background: a powerful and improved technique, proton induced x-ray emission (pixe) has been performed-yielding the elemental composition of 17 samples of surgically excised malignant and normal tumors of breast tissue. the samples without any further process as thick targets were put on capton foil backing. there are no homogenizing processes. the pixe spectra analysis was performed using he n...

postpartum depression (ppd) is a major depressive disorder that most often emerges within 6 to 12 weeks of delivery, but can happen any time up to 1 year after birth. in developed countries, the incidence of postnatal depression is about 10-15% in adult women depending upon the diagnostic criteria, timing of screening and screening instruments used. mothers with depressive symptoms have been fo...

An important essential trace element found in every tissue of the human body is zinc. The pervasive role of zinc in the metabolic function of the body results from its function as a cofactor of a multitude of enzymes. As zinc metalloenzymes are found in every known class of enzymes, the element plays an important function in every conceivable biochemical pathway. It is now clearly established t...
