BACKGROUND To understand the effect of selenium intake on health, it is important to identify sensitive and population-specific biomarkers of selenium status. OBJECTIVE The objective of this systematic review was to assess the usefulness of biomarkers of selenium status in humans. DESIGN The methods included a structured search strategy on Ovid MEDLINE, EMBASE (Ovid), and Cochrane databases...

Selenium is a naturally occurring substance that is toxic at high concentrations but is also a nutritionally essential element. Hydrogen selenide is the most acutely toxic selenium compound. Acute (short-term) exposure to elemental selenium, hydrogen selenide, and selenium dioxide by inhalation results primarily in respiratory effects, such as irritation of the mucous membranes, pulmonary edema...

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...

Potato consumption provides significant dietary contributions to several essential minerals, but the effects of cultivar and planting site are not well-understood. The mineral content of 16 cultivars, grown at 5 locations, was measured using inductively coupled plasma-optical emission spectroscopy and evaluated on a per serving basis for percent recommended daily intake (% RDI), emphasizing som...
