The present study was conducted on removal of zinc in a continuous flow system by Aspergillus sp. during its growth. The fungal strain was isolated from industrial wastewater. The experiments under continuous culture conditions were performed in two reactors of working volume 650ml and 3 litres respectively. The experiments were conducted using sugar concentrations of 10, 15 and 20g/l and at di...

biological methods based on using soil beneficial microorganisms’ potentials for creating symbiosis relationship with plants by modifying genetic structure of plants resulting in improving nutritional status and crops quality. this study was conducted in order to investigate the effect of piriformospora indica inoculation on root colonization and uptake and transportation of phosphorus, zinc an...

abstract heavy metals enter to human food chain through the plant and soil contamination. it is very important to evaluate the affecting factors on plant uptake of heavy metals. in this study the effects of copper and zinc availability on cadmium uptake of root and shoot of corn and sunflower was investigated. the experiment was carried out with a factorial arrangement, two species of plants (s...

objective: zinc deficiency is an important health problem in developing countries. the aim of this study was diagnosis of zinc deficiency among young female students of tehran university of medical sciences. materials and methods: this cross sectional study evaluated 420 medical and paramedical students of tehran university in 2005. all of them were female and in the first year of their educati...

Zinc (Zn(2+)) appears to be intimately involved in insulin metabolism since insulin secretion is correlated with zinc secretion in response to glucose stimulation, but little is known about the regulation of zinc homeostasis in pancreatic beta-cells. This study set out to identify the intracellular zinc transient by imaging free cytosolic zinc in HIT-T15 beta-cells with fluorescent zinc indicat...

Zinc deficiency has a great impact on growth and development, especially in malnourished children. Zinc is important in both local and systemic immunity. The aim of this study was to assess the impact of zinc supplementation on the cytokine, tumor necrosis factor  (TNF and diarrhea in severely undernourished under-five children of low-income families. A randomized double blind pre-test post...

The purpose of this study was to examine the relationship between the zinc nutritional status and the factors associated with serum zinc concentration in the elderly patients in two nursing facilities: body mass index (BMI), the level of care, the grade of bedriddenness, and the grade of cognitive function. The estimations of the hematological constituents, physical index, and dietary survey we...

Zinc is an essential trace element required for bone formation, however not much has been clarified yet for its role in osteoblast. We hypothesized that zinc would increase osteogenetic function in osteoblasts. To test this, we investigated whether zinc treatment enhances bone formation by stimulating osteoblast proliferation, bone marker protein alkaline phosphatase activity and collagen synth...

Introduction: Zinc plays a vital role in various biological functions and physical growth. More than 300 enzymes in body need zinc for proper function. In this study, the concentration of the zinc micronutrient in breast milk was evaluated and analyzed at the first month of breastfeeding. Materials and Methods: This was a descriptive study of 150 breastfeeding mothers in the 2014 who had given...
