in order to study the effect of intercropping of corn with bean and bitter vetch and farmyard manure (fym) on corn nutrition, a factorial experiment was carried out on the basis of randomized complete blocks design with three replications. the factors were types of intercropping systems at levels of sole bean, bean+corn, sole bitter vetch, bitter vetch+corn, sole corn, and fym at levels of 0, 3...

the aim of this research was to evaluate the average concentrations of micronutrients including: copper (cu), iron (fe), manganese (mn) and zinc (zn) in the shoots of different cultivars of wheat in stem elongation stage in a soil contaminated with cadmium (cd). the treatments consisted of three levels of cd (0 (as control, cd0), 40 (cd40) and 80 (cd80) mg cd/kg soil) and fourteen different cul...

BACKGROUND Metal pollution of waterways directly affects human health and can impact the food chain. Seafood living in polluted water can accumulate trace metals. The purpose of this study was to analyze the toxic metals Pb and Cd and the dietary essential metals Zn and Mn in 120 cans of tuna species from four different brands processed in Iran and purchased in 2012. RESULTS The mean level of...

the essential nutrients in the pharmacological plants play a significant role in the remedy of illnesses but, these elements at high levels; can also be dangerous and toxic. the aim of this study was to determine the concentration of macro (mg, ca, p, and k) and micro (cu, zn, fe and mn) essential elements in seven indigenous pharmacological plants growing in fars province, southern iran. they ...

This study was conducted to investigate the effects of vanadium pentoxide (V2O5), ascorbic acid (AA), and alpha-tocopherol (α-TOH) on apoptotic, cytotoxic, and genotoxic activity. Groups of five Hsd:ICR mice were treated with the following: (a) vehicle, distilled water; (b) vehicle, corn oil; (c) AA, 100 mg/kg intraperitoneally (ip); (d) α-TOH, 20 mg/kg by gavage; (e) V2O5, 40 mg/kg by ip injec...

We studied the levels of twenty two free amino acids in the striatum and olfactory bulb of mice treated during nine weeks with daily intraperitoneal injections of manganese chloride at a concentration of 5.0 mg Mn+2/kg body weight. In the olfactory bulb the contents of alanine, alpha-amino-n-butyrate, arginine, asparagine, aspartate, citrulline, GABA, glutamate, glycine, isoleucine, leucine, me...

Manganese (Mn) is a metal required by biological systems. However, environmental or occupational exposure to high levels of Mn can produce a neurological disorder called manganism, which has similarities to Parkinson's disease. Diethyl-2-phenyl-2-tellurophenyl vinylphosphonate (DPTVP) is an organotellurium compound with a high antioxidant activity, especially in the brain. The present study was...

to investigate the effect of different amounts of fe and mn on qualitative and quantitative traits of forage maize (zea mays l.) hybrid single cross 704, an experiment was conducted as a factorial in a randomized complete block design with 16 treatments and three replications at qaneat city (southern khorasan province) in 2010. treatments consisted of 4 levels of feso4 (no fertilizer as control...
