The 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...
متن کاملEffects of Different Rates of Selenium Fertilizer and Cow Manure on Selenium Uptake in Festuca arundinacea
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 ...
متن کاملSelenium in Plants
Selenium (Se) and sulfur (S) are chemically similar. Most plants cannot discriminate between the two, with the exception of Se hyperaccumulator species, which preferentially accumulate Se over S. Genetic engineering of various genes from the S/Se assimilation pathway has successfully enhanced plant Se tolerance, accumulation, and volatilization, in both laboratory and field. Results from genomi...
متن کاملSelenium Metabolism in Plants
Selenium (Se) is an essential nutrient for many organisms, but also toxic at higher levels. While certain algae require Se to make selenoproteins, no such requirement has been shown for higher plants. Still, plants readily take up and assimilate Se using sulfur (S) transporters and biochemical pathways, and can also volatilize methylated Se. Some plants can even hyperaccumulate Se to levels aro...
متن کاملSelenium in Higher Plants.
Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-sensitive. This review summarizes knowledge of the physiology and biochemistry of both types of plants, particularly with regard to Se uptake ...
