Using PIXE (proton-induced X-ray emission), we simultaneously determined the concentrations of Se, Ca, Fe, Cu, Zn, Br, and Pb in blood serum from 56 pregnant women, 25 healthy controls, and 31 others with twin pregnancy or some complicating condition (diabetes, hypertension, epilepsy, hepatosis gravidarum, pre-eclampsia, small baby), and in cord-blood serum from 21 newborns. Pellets, pressed fr...

Pearl millet is a multipurpose grain/fodder crop of the semi-arid tropics, feeding many of the world's poorest and most undernourished people. Genetic variation among adapted pearl millet inbreds and hybrids suggests it will be possible to improve grain micronutrient concentrations by selective breeding. Using 305 loci, a linkage map was constructed to map QTLs for grain iron [Fe] and zinc [Zn]...

Two sensitive wavelength (SW) selection methods combined with visible/near infrared (Vis/NIR) spectroscopy were investigated to determine the levels of some trace elements (Fe, Zn) in rice leaf. A total of 90 samples were prepared for the calibration (n = 70) and validation (n = 20) sets. Calibration models using SWs selected by LVA and ICA were developed and nonlinear regression of a least squ...

Brain, liver, kidney and muscles demonstrate significant changes in essential trace element (Cu, Zn, Mn and Fe) level in adult female mice given 30, 60 and 120 ppm sodium fluoride (NaF) in drinking water. These changes involve excess removal or accumulation of these trace elements in respective tissues. Changes observed were dose dependent and significant at 120 ppm NaF concentration in drinkin...

Wheat is a major staple food crop providing about 20% of dietary energy and proteins, and food products made of whole grain wheat are a major source of micronutrients like Zinc (Zn), Iron (Fe), Manganese (Mn), Magnesium (Mg), Vitamin B and E. Wheat provides about 40% intake of essential micronutrients by humans in the developing countries relying on wheat based diets. Varieties with genetically...

The results of analysis of soil and tree leaves samples collected from heavy traffic affected area of Agra city show that average concentration of Cu, Fe, Ni, Pb, Mn and Zn ranged from 0.953.42, 3.2811.26, 2.18-4.05, 3.04-8.10, 0.91-1.42 and 2.83-5.94 ppm , respectively in soil samples. The maximum concentration of Ni (2.68ppm) and Co (4.82 ppm) was observed in the leaves of Ficus religiosa and...

An experiment of 10 weeks duration was conducted on 48 weaned female rats (285.2 ± 1.95 g) of strain Sprague Dawley to study the effect of replacing dietary Zn (12 ppm) supplementation from inorganic (ZnCO3) to organic (Zn nicotinate; Zn-nic) source at lower (6 or 9 ppm) or equal (12 ppm) levels on Zn retention and ovarian follicular population. Higher Zn concentration (on day 42) in serum (P<0...

AIM A study was undertaken to investigate the effect of organic zinc (zinc nicotinate, Zn-nic) supplementation (6, 9, and 12 ppm) compared to inorganic zinc (12 ppm) on growth performance, hematology, serum biochemical constituents oxidative stress, and immunity in weaned female Sprague-Dawley rats. MATERIAL AND METHODS A 48 weaned rats (285.20±1.95 g) were randomly distributed to 4 dietary t...

Biofortification, a method for increasing micronutrient content of staple crops, is a promising strategy for combating major global health problems, such as iron and zinc deficiency. We examined the acceptability of recipes prepared using iron- and zinc-biofortified pearl millet (FeZnPM) (~80 ppm Fe, ~34 ppm Zn, varietal ICTP-8203), compared to conventional pearl millet (CPM) (~20 ppm Fe, ~19 p...

in order to study concentrations of soil micro and heavy metal elements in some saffron planting regions of birjand province, an experiment was performed as factorial layout based on a completely randomized block design with three replications at year 2013. treatments were three field ages (annual, triennial and quinquennial) and five saffron regions including aryan shahr, hosseinabad, khosef, ...
