Selenium metabolism in animals and humans.Focuses on the differences in the metabolism of selenium (Se) between animals and humans. Major differences of Se metabolism; Information on the absorption, transport, distribution, excretion, retention and metabolic transformation of Se.P.D.WhangerEBSCO_AspJournal of Environmental Scie...
This paper proposes two thought experiments to demonstrate that our current treatment of animals is immoral. The first thought experiment involves aliens coming to earth and doing to us what we do to animals鈥攅ating us, confining us in farms and zoos, doing experiments on us, etc. Drawing ...
Selenium (Se) and iodine (I) are very important trace mineral for animals and human health. Selenium is an essential constituent of the antioxidant enzyme GSH-Px, while I as a thyroid hormone play a crucial role in regulating body metabolism. The aim of this study was to provide preliminary...
SepW is one of the most abundant SePs in mammals. This small 9-kDa SeP is found in the cytosol and has a high muscle and brain concentration [23]. Generally, SepW is required for muscle metabolism in animals. However, the role of this protein is still unknown. It has been revealed ...
bisulcatus plants used in non-choice experiments were collected and analyzed for Se speciation. Samples were washed and flash-frozen using liquid nitrogen. Samples were kept frozen at -80°C to prevent Se metabolism, and Se speciation was determined using XANES as described by Marcus et al. [...
Selenium (Se) is an essential micronutrient for humans, animals and some lower plants at very low concentrations, whereas it is extremely toxic at higher doses. Furthermore, living organisms become exposed to high Se concentrations via both anthropogenic
part of a number of important proteins, particularly enzymes involved in antioxidant defense mechanisms, thyroid hormone metabolism, and redox control of intracellular reactions. In humans and animals, selenium plays a role in protecting tissues from oxidative damage as a component of glutathione ...
The metal zinc is the second most common trace metal in the body and, as an essential micronutrient, plays many important roles in biological systems. Zinc also plays crucial roles in the synthesis, storage, and secretion of insulin and in the actions of insulin on carbohydrate metabolism15. ...
GO enrichment analysis showed that the differentially expressed proteins in the -Se group were significantly enriched in processes such as “energy metabolism”, “cell growth and death”, “immune system”, and “antioxidant activity” (Fig. 6A). KEGG analysis indicated that the differentially ...
Selenium has a highly specific metabolism centered around its incorporation as selenocysteine into selenoproteins. An outline of this metabolism has emerged from recent molecular biological and biochemical studies of bacteria and animals. A unique tRNA, designated tRNA[Ser]Sec, is charged with L-serine...
