an experiment was conducted to optimize consumption of zinc and evaluate of zinc effects on quantitative and qualitative traits of winter wheat under saline soil condition. it was done by three replications in randomized complete block design. the experiment had four treatments as control without zn, 40 kg.ha-1 zn as znso4, 80 kg.ha-1 zn as znso4 in soil and 120 kg.ha-1 zn as znso4 in soil. ele...

The aim of our study was to evaluate the mineral composition (Zn, Cu, Ca, Fe, Mg, P) of breast tumor tissue and hair, and to investigate the role of Zn and Cu contents in diet on tumor development, with DMBAinduced rat breast cancer being the experimental model. Female Sprague-Dawley rats were divided into study groups which, apart from the standard diet, were treated with Zinc ions (Zn) or Cop...

Rice is a staple food for at least 50% of the world’s population. Therefore, it is one of the most important crop plants on Earth (Lucca et al., 2002). However, milled rice is a poor source of essential micronutrients such as Fe and Zn (Bouis and Welch, 2010), whose deficiencies affect over three billion people worldwide, mostly in developing countries (Welch and Graham, 2004). Fe and Zn malnut...

A research was conducted at Pistachio Research Institute in Rafsanjan, Iran, to evaluate the effects of P. vera L. ‘Badami’, P. vera L. ‘Sarakhs’ and P. mutica F and M. ‘Beneh’ rootstocks on mineral content of leaves and kernels of ‘Owhadi’, ‘Kalleh-ghuchi’ and ‘Ahamd-aghaii’ pistachio scion cultivars. Twenty year old trees of these combinations were used during study over 2003 and 2004. Leaves...

Our research indicates that in Kerman and Fars provinces the phenomenal growth of seeds dietary supplements have received considerable interest, because of their presumed safety and potential, nutritional and functional effects. This interest can be attributed to several social and economic factors, including consumer beliefs. The amount of 7 minerals Zn, Cu, Fe, Mg, Mn, K and Na, were determin...

Th e chemical composition and nutritional value of a wild edible ectomycorrhizal mushroom from southwestern Anatolia, Tricholoma anatolicum, were analyzed. Moisture, crude oil, protein, ash, total carbohydrate content, and mineral composition of the mushrooms studied, including Fe, Na, K, Zn, Cu, Ca, Cd, and Pb, were determined. Th e energy values of the samples were also calculated. Th e analy...

Three pulse photon echo peak shift spectroscopy and transient grating measurements on Zn-substituted cytochrome c, Zn-tetraphenylporphyrin, and Zn-protoporphyrin IX are reported. The effects of protein conformation, axial ligation, and solvent are investigated. Numerical simulations of the peak shift and transient grating experiments are presented. The simulations employed recently derived opti...

BACKGROUND Wild rodents are suitable for monitoring environmental pollution and exposure risk assessment for people living in contaminated areas. The content of selected risk elements in the femora of bank vole (Myodes glareolus), yellow-necked mouse (Apodemus flavicollis) and wood mouse (Apodemus sylvaticus) was estimated from the Kolíňany area of Slovakia, which is characterized by a high deg...

I. Rats were made severely iron-deficient by feeding with Fe-deficient diets, which contained adequate amounts of zinc. 2. Ten days after an oral dose of 250 ,ug %n the Fe-deficient rats had retained 17 yo whereas control rats had retained only 8 yo of the dose. 3. When unlabelled Zn was given intravenously to the Fe-deficient and control rats there was a reduction in retention of the orally ad...

Zn abundances, derived from a model atmosphere analysis of the λ6362.35 Å Zn i line, are presented for 44 thin disk, 10 thick disk and 8 halo dwarf stars in the metallicity range −1.0 < [Fe/H] < +0.2. It is found that [Zn/Fe] in thin disk stars shows a slight increasing trend with decreasing metallicity reaching a value [Zn/Fe] ≃+0.1 at [Fe/H] = −0.6. The thick disk stars in the metallicity ran...
