Currently, pollution of our agricultural soils and waters is increasing and is often associated with many human health ailments. Soils contaminated with low levels of heavy metals and other trace elements are frequently used for growing vegetable crops and in such a situation, these toxic contaminants often accumulate in the edible portions of these agricultural plants and thereby enter the hum...

We have investigated the growth and reactivity of chromium layers deposited onto a thin alumina film at room temperature and at 570 K. The interaction between Cr and the Al2O3/NiAl(1 1 0) surface leads to partial oxidation to Cr2þ and Cr3þ species. Complete oxidation to Cr3þ was achieved using moderate O2 doses at room temperature in vacuum. Cr has also been deposited in an O2 background pressu...

BACKGROUND Chromium (Cr) is considered to be a risk factor to the cardiovascular effects of fine particulate matter components to PM2.5 from traffic in highway patrol officers. RKIP (raf kinase inhibitor protein) is a physiological inhibitor of GRK-2 (G-protein-coupled receptor kinase 2) and affects β-adrenergic signaling and contractile activity in cardiomyocytes. OBJECTIVES In this study, w...

background: the presence of heavy metals in the environment especially in water supplies have caused many concerns because of their toxicity and non-degradability. hexavalent chromium (cr) is one of the most toxic metals which is used in many industries, so it is essential to remove it from industrial wastewater. in this study, we made a comparison between different adsorption isotherms in the ...

Iron(II) in buffer medium and in presence of oxalate has been proposed as a new electron transfer reagent or reducing agent for the selective determination of chromium(VI) in presence of several other metal ions such as Mo(VI), U(VI), V(IV) etc. The method consists in taking a chromium(VI) solution [ containing 3-11mg of Cr] into a buffer medium of pH ~ 4.05.2 containing about 0.040.10M potassi...

Dietary methionine (met) is reported to enhance antibody production and boost cell-mediated immunity in chickens. Methionine deficiency has been shown to affect the development of the lymphoid organs and the generation of antibodies in chickens. This study is designed to investigate the effects of met deficiency on IgA+ B cells and immunoglobulins (sIgA, IgA, IgG and IgM) for a 6 wee...

BACKGROUND A geothermal ecosystem located at Tantloi, India has been found to be an interesting habitat for microbes of diverse nature. However, the microbial diversity of this habitat is poorly explored. In this study, a detailed phylogenetic study has been carried out to understand the bacterial diversity of this habitat and to identify prospective metal reducers using culture independent app...

To investigate the effect of dietary chromium (Cr) as Cr methionine (CrMet) on growth performance, carcass traits, pork quality, meat colour and expression of meat colour-related genes in growing-finishing pigs, 189 crossbred Duroc×(Landrace×Yorkshire) growing-finishing pigs (male, castrated, average initial BW 74.58±1.52 kg) were selected and randomly allocated into four groups. Dietary treatm...
