Fe, Cu, and Zn are of widespread neurobiological importance, but must be regulated closely as too much or too little of these metals can have adverse effects on brain function. Recent evidence from nutritional models notes that the hippocampus is particularly vulnerable to Fe and Zn deficiencies. We recently performed a quantitative trait loci (QTL) analysis as a preliminary step in identifying...

The deficiency of essential micronutrients and excess of toxic metals in cereals, an important food items for human nutrition, can cause public health risk. Therefore, before their consumption and adoption of soil supplementation, concentrations of essential micronutrients and metals in cereals should be monitored. This study collected soil and two varieties of wheat samples-Triticum aestivum L...

diagnosis and recommendation integrated system (dris) can be used as efficient methods to interpret the results of plant analysis and the nutritional diagnosis in crops and fruit trees. to establish dris norms in onion (allium cepa l) leaf samples were collected from 50 fields and n, p, k, ca, mg, fe, mn, zn, cu and b concentrations were determined. on the bases of yield, the studied fields wer...

The Thriposha programme is a community-level nutrition intervention in Sri Lanka that provides a combination of energy, protein and micronutrients as a 'ready-to-eat' cereal-based food. We measured the bioavailability of Fe and Zn from Thriposha formula at two different molar ratios of Zn:Fe in order to determine the effect on Fe and Zn absorption. Children 4-7 years (n 53) were given a meal pr...

New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...

Dietary minerals Zn, Fe, and Ca are antagonistic to Cd absorption. We showed earlier that rats fed a rice-based diet with a marginal content of these nutrients absorbed more Cd than rats fed adequate Zn-Fe-Ca (Environ. Sci. Technol., 36 (2002) 2684-2692). The present experiment was designed to determine the effects of marginal dietary Zn, Fe, and Ca on the uptake and turnover of Cd in the gastr...

heavy metal concentrations in surface water, wastewater and sediments collected from mighan lake in markazi province, iran were analyzed, and assessment contamination were evaluated according to the water and sediment quality guidelines. the results showed that the average concentrations of heavy metals in water were ranked as: ni> cr> pb> fe> cu> zn. in comparison with results the background v...

Nutritionally enhanced beans (NEB) with more Fe and Zn than conventional beans (CB) and nutritionally enhanced maize (NEM) with more tryptophan and lysine than conventional maize (CM) were developed as part of a crop-biofortification strategy to improve human nutrition. Proxy measures were used to assess Fe and Zn bioavailability and protein digestibility of a bean recipe (fríjol sancochado) an...

Alam, M. K. and O. E. Maughan (1992). "THE EFFECT OF MALATHION, DIAZINON, AND VARIOUS CONCENTRATIONS OF ZINC, COPPER, NICKEL, LEAD, IRON, AND MERCURY ON FISH." Biological Trace Element Research 34(3): 225-236. Acute and chronic toxicity tests for malathion, diazinon, copper (Cu), mercury (Hg), lead (Pb), zinc (Zn), nickel (Ni), and iron (Fe) were conducted. Mortalities of Barilius vagra and Cyp...

abstract a hydroponics experiment was conducted to compare effect of fe-deficiency on concentration, uptake, translocation of fe, zn, mn in some plants. a completely randomized block design in triplicates was conducted in research greenhouse. seven plants with different fe-efficiency contained two bread wheat genotypes (triticum aestivium l. cvs. backcross roshan and qods), triticale (x. tritic...
