zinc is one of the most important micronutrient with essential role in biochemical regulation of the body functions. the importance of zinc in pregnancy period was widely studied in various countries. variation in zinc plasma levels during pregnancy needs more investigation, because maternal zinc deficiencies may cause some severe abnormalities in the fetus. in this study the plasma levels of z...

introduction recurrent oral aphthous is one of the most common ulcerative lesions of the oral cavity which no specific treatment has been introduced for it, sofar. some studies suggest the zinc deficiency as one of the etiologic factors in aphthous ulcers and also in other experimental studies, zinc composition has been effective in aphthous treatment. the aim of this stud was to determinate th...

S printing has previously been described as consisting of a series of phases: an acceleration phase from 0 to 10 m, a transition phase, and then a maximum velocity phase from 36 to 100 m during a 100-m sprint (7). Mero et al. (34) described the acceleration phase as being in the first 30–50 m, followed by a maximum velocity phase and a phase of deceleration. However, for many sporting activitie...

objective: major depression is a mood disorder that causes changes in physical activity, appetite, sleep and weight. regarding the role of zinc in the pathology of depression, the present study was aimed to investigate the effects of zinc supplementation in the treatment of this disease. methods: this study was a double-blind randomized clinical trial. forty four patients with major depression ...

Zinc was electrodeposited from an acidic sulphate solution on commercial steel sheet substrates galvanostatically at 10, 20, and 100 mA/cm2. The steel substrates had an average roughness number of 1.34 microns and a high percentage of its grains had their (111) planes parallel to the plate surface. During electrodeposition at 10 mA/cm2, on some specimens, there was an intense potential fluctuat...

Zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. The efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of Na+ and make depolarization Na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. Also it is an effective blocker of one subtype of tetrodoxine (...
