Biological interaction of selenium with other trace elements in chicks.
Studies were conducted to determine whether or not elements whose valence shell of electrons was similar to that of selenium would reverse the toxicity of selenium to chicks. The elements studied were arsenic, tellurium, tin, and lead. Each of these elements, when added to the diet of chicks, reversed the toxicity of 25 ppm selenium as measured by weight gain. In spite of the protection afforde...
متن کاملThe selenium content of SEPP1 versus selenium requirements in vertebrates
Selenoprotein P (SEPP1) distributes selenium (Se) throughout the body via the circulatory system. For vertebrates, the Se content of SEPP1 varies from 7 to 18 Se atoms depending on the species, but the reason for this variation remains unclear. Herein we provide evidence that vertebrate SEPP1 Sec content correlates positively with Se requirements. As the Se content of full length SEPP1 is genet...
متن کاملSelenium Fertilization of Pastures for Improved Forage Selenium Content
Selenium (Se) was applied to perennial ryegrass (Lolium perenne) and subterranean clover (Trifolium subterranean) pasture as a fertilizer to determine the effect of Se form and concentration on Se accumulation in subsequent forage growth. Treatments were a no Se control, 0.6 kg/ ha Se as sodium selenate, and 0.6, 1.1, and 2.2 kg/ha Se as sodium selenite, all applied to pasture plots with low so...
متن کاملEstimation of the relative biological availability of inorganic selenium sources for ruminants using tissue uptake of selenium.
An experiment was conducted to estimate the relative bioavailability of inorganic Se sources based on tissue Se deposition following supplementation at high dietary levels. Twenty-eight crossbred wethers averaging 50 kg initial weight were assigned randomly to seven treatments that were fed for 10 d. The basal diet contained .18 mg/kg Se (DM basis). Dietary Se was added at 0, 3, 6 or 9 mg/kg as...
متن کاملThe protective effect of selenium nanoparticles and selenium against paracetamol
Objective(s): Nanotechnology has enabled researchers to synthesize nanosize particles that possess increased surface areas. Compared to conventional microparticles, it has resulted in increased interactions with biological targets.The objective of this study was to determine the protective ability of selenium nanoparticles compared to selenium against parasetamol hepatotoxicity and GPX concentr...
