The purpose of this study was to evaluate the relationship between zinc and the growth and development of young children. The parents of 8102 young children were surveyed in person by a trained surveyor using structured questionnaires. The hair zinc concentration of the children was determined using an atomic absorption spectrophotometer. The height, weight, sitting height, and head circumferen...

This study was designed to evaluate the zinc metabolism in adults of both sexes with thyroid disease. Plasma and erythrocyte zinc concentration and urinary zinc excretion were investigated. The mean concentration of plasma zinc in hypothyroid patients and in euthyroid patients, previously either hyperthyroid or hypothyroid, was lower than that of control subjects, whereas no statistically signi...

Zinc is an essential element for numerous cellular processes, therefore zinc homeostasis is regulated in living organisms. Fluorescent sensors have been developed as important tools to monitor the concentrations of readily exchangeable zinc in live cells. One type of biosensor uses carbonic anhydrase (CA) as the recognition element based on its tunable affinity, superior metal selectivity, and ...

The levels of carbonic anhydrase I and II isozymes in human erythrocytes were determined using the single radial immunodiffusion method in 53 patients (29 males, 24 females) under chronic hemodialysis, and zinc concentration in erythrocytes were also determined. Both carbonic anhydrase. I and II levels and zinc concentration in erythrocytes were observed to be significantly increased in chronic...

background : preeclampsia is one of the commonest causes of prenatal and maternity related death in the world. preeclampsia is caused by multiple factors and finding any factor related to this disorder can help on time prevention of this disease, which reduces the mortality of mothers and infants. zinc deficiency is a possible risk factor for risky pregnancies and the results of studies on this...

the experiment in this study was conducted as a completely randomized block design with ten treatments and four replications. treatments included: to- control, t1- 50g of zn per tree as broadcast application, t2-100g zn per tree, broadcast application, t3- 200g zn per tree as broadcast application, t4- 50 g zn per tree as band application, t5- 50g zn per tree, band application, t6-100g zn per t...

Neuropsychological behavior via activation of the hypothalamic-pituitary-adrenal (HPA) axis was analyzed using young mice fed a zinc-deficient diet for 2 weeks. Serum corticosterone concentration was significantly increased after 2-week zinc deprivation, whereas zinc concentration in the brain was not decreased. In the resident-intruder test, the rate of mice that exhibited aggressive behavior ...

apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. infants and young children are very susceptible to amount of trace elements. copper and zinc are two elements that add in infant food. lead and cadmium are heavy metals that enter to food chain unavoidably. dpasv is a benefit and applicable method for measurement of trace elements in food produc...
