Sprouts of several plants (10 families and 28 species) were cultivated in a high selenium environment, and the chemical species of selenium in these selenium-enriched sprouts were identified by using high-performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICPMS). Cultivation of sprouts of kaiware daikon (type of radish) with 5.0 microg/ml or 10.0 microg/ml of s...

Bacterial anaerobic respiration using selenium oxyanions as the sole electron acceptor primarily result in the precipitation of selenium biominerals observed as either intracellular or extracellular selenium deposits. Although a better understanding of the enzymology of bacterial selenate reduction is emerging, the processes by which the selenium nanospheres are constructed, and in some cases s...

Background and aim: Atopic dermatitis (AD) is a chronic, inflammatory, pruritic skin disease usually observed in patients with other allergies. Decreased selenium levels and improvement with selenium supplement are reported in AD. The aim of this study was to compare serum and whole blood selenium in children with AD and control group.Materials and Methods: In an age-se...

Selenium has important roles as an antioxidant, in thyroid hormone metabolism, redox reactions, reproduction and immune function, but information on the selenium status of Thai children is limited. We have assessed the selenium status of 515 northeast Thai children (259 males; 256 females) aged 6 to 13 years from 10 rural schools in Ubon Ratchthani province. Serum selenium (n=515) was analyzed ...

One of the crucial elements for livestock and human nutrition is selenium and its deficiency or toxicity can harm human and livestock health. The present study is designed with the aim of studying the effect of different levels of selenium fertilizer (Selcote-Ultra) and cow manure on the uptake of selenium in tall fescue. For this purpose, a pot experiment with complete randomized block design ...

in order to study the effects of salicylic acid and selenium application on yield and yield components of rainfed wheat cultivars, a field experimental was carried out as factorial based on randomized complete block design with four replications in the research station of islamic azad university- arak branch, iran in 2010-2011 growing season. the treatments were salicylic acid and selenium. sal...

Nickerson, Walter J. (Rutgers, The State University, New Brunswick, N.J.) and Giuseppe Falcone. Enzymatic reduction of selenite. J. Bacteriol. 85:763-771.-1963. Extraction of boiled yeast extract with n-hexane removed its ability to restore selenite-reducing capacity in dialyzed enzyme preparations obtained from baker's yeast or from Candida albicans. Menadione or thiodione substituted for the ...

The article reviews the progress in basic research of selenium and cancer prevention during the past decade. Special emphasis is placed on the following four major areas of discussion: 1) chemical forms of selenium and anticarcinogenic activity; 2) selenium-enriched food; 3) in vitro effects of selenite vs. monomethylated selenium; and 4) aromatic selenium compounds. It is clear that basic rese...

background: critical macromolecules of cells such as dna are in exposure to damage of free radicals that induced from the interaction of ionizing radiation with biological systems. selenium and vitamin-e are natural compounds that have been shown to be a direct free radical scavenger. the aim of this study was to investigate the radioprotective effect of selenium and vitamin-e separately and sy...
