Background: The immune response of aged broiler breeder hens is influenced by many factors including obesity and aged lymphatic organs, but may improve by increasing the bioavailability of various nutrients such as zinc (Zn). Dietary supplementation of phytase can improve Zn availability in senescent broiler breeder hens. Aims:</st...

Zinc ions highly concentrate in hippocampus and play a key role in modulating spatial learning and memory. At a time when dietary fortification and supplementation of zinc have increased the zinc consuming level especially in the youth, the toxicity of zinc overdose on brain function was underestimated. In the present study, weaning ICR mice were given water supplemented with 15 ppm Zn (low dos...

background: to assess the therapeutic effects of oral zinc supplementation on acute watery diarrhea of children with moderate dehydration. methods: all 9-month to 5-year-old children who were admitted with acute watery diarrhea and moderate dehydration to the children ward of motahari hospital, urmia, iran in 2008 were recruited. after the application of the inclusion and exclusion criteria, th...

Background: Physical activity has a range of effects on male reproductive function depending upon the intensity and duration of the activity. Materials and Methods: In order to investigate the protective effects of nano zinc oxide on endurance exercise induced testicular oxidative stress, 30 adult male Wistar rats were randomly divided into the following groups: control group (n=10); exercised ...

UNLABELLED Child eating behaviors play an important role in nutrient intake, ultimately affecting child growth and later outcomes in adulthood. The study assessed the effects of iron-folic acid and zinc supplementation on child temperament and child eating behaviors in rural Nepal. Children (N = 569) aged 4-17 months in Sarlahi district, southern Nepal were randomized to receive daily supplemen...

Nuclear factor-kappaB (NF-kappaB) and AP-1 nuclear transcriptional factors regulate expression of multiple genes involved in tumor growth, metastasis and angiogenesis; however, the relative contribution of each factor to cancer initiation and progression has not been established. Prostate carcinogenesis involves transformation of normal zinc-accumulating epithelial cells to malignant cells that...

It has previously been established that zinc (Zn) supplementation increases bone dimensions and strength in growing rats. The present study aims at describing differences in the localization of loosely bound or free zinc ions, as revealed by autometallography (AMG), that might take place in the skeleton of growing rats following alimentary zinc depletion and supplementation. Male Wistar rats, 4...

Plasma concentrations of some micronutrients are altered in the setting of acute infectious or inflammatory stress. Previous studies have provided conflicting evidence concerning the extent and direction of changes in plasma zinc concentrations during the acute phase response. We carried out an observational cohort study in 689 children enrolled in a randomized trial of zinc supplementation dur...

ZINC IMBALANCE AND THE OPPORTUNITY OF ZINC SUPPLEMENTATION IN ALCOHOLICS AND DRUG USERS (Abstract): Zinc deficiency is well-documented to be associated with alcoholism, being considered a consequence of unbalanced eating habits in such patients. The present review focuses on zinc imbalance in drug addicts and on the po ssible beneficial role of zinc administration as dietary supplement. All rel...
