Selenium is an essential nutrient for animals, microorganisms and some other eukaryotes. Although selenium has not been demonstrated to be essential in vascular plants, the ability of some plants to accumulate and transform selenium into bioactive compounds has important implications for human nutrition and health, and for the environment. Selenium-accumulating plants provide unique tools to he...

An experiment was conducted to compare the effect of selenium sources on performance, Se incorporation into certain poultry tissues (blood, liver and breast muscle) and eggs, hatchability, glutathione peroxidase activities in tissues and eggs in broiler breeder. Broiler breeder hens were allocated to six diet treatments factorially arranged with three selenium sources (Sodium selenite, Selenium...

Colonization of the gastrointestinal tract and composition of the microbiota may be influenced by components of the diet, including trace elements. To understand how selenium regulates the intestinal microflora, we used high-throughput sequencing to examine the composition of gut microbiota of mice maintained on selenium-deficient, selenium-sufficient, and selenium-enriched diets. The microbiot...

The last few decades have seen an overwhelming increase in the amount of research carried out on use inorganic nanoparticles. More fascinating is tremendous progress made chalcogen and chalcogenide nanoparticles cancer theranostics. These nanomaterials, which were initially synthesized through chemical methods, now been efficiently produced using different plant materials. paradigm shift toward...

BACKGROUND Selenium is part of the antioxidant defence system in animals and humans. The available selenium concentration in soil is low in many regions of the world. The purpose of this study was to evaluate the effect of organic versus inorganic selenium supplementation on selenium status of ewes, their lambs, and slaughter lambs. METHODS Ewes on four organic farms were allocated five or si...

AIM To determine whether selenium supplementation of parenteral nutrition with 3 micrograms/kg/day of selenious acid is safe and effective in improving the selenium status of preterm infants. METHODS Thirty eight preterm infants with mean (SEM) birthweight of 1171 (38) g and gestational age 29 (0.3) weeks were randomly allocated to a non-supplemented (PN-selenium, n = 19) or supplemented (PN+...
