Selenium as a Versatile Center in Fluorescence Probe for the Redox Cycle Between HClO Oxidative Stress and H2S Repair
Selenium is a biologically important trace element and acts as an active center of glutathione peroxidase (GPx). GPx is the important antioxidant enzyme to protect organisms from oxidative damage via catalyzing the reaction between ROS and glutathione (GSH). Mimicking the oxidation–reduction cycles of the versatile selenium core in GPx, we can develop fluorescence probes to detect oxidation and reduction events in living systems. The cellular redox balance between hypochloric acid (HClO) and hydrogen sulfide (H2S) has broad implications in human health and diseases, such as Alzheimer’s disease (AD). Therefore, ...

Selenium, vitamin E supplements can increase risk of prostate cancer in some men
High-dose supplementation with both the trace element selenium and vitamin E increase the risk of high-grade prostate cancer. But importantly, this risk depends upon a man’s selenium status before taking the supplements. "Men using these supplements should stop, period. Neither selenium nor vitamin E supplementation confers any known benefits -- only risks," the lead author stated. "While there appear to be no risks from taking a standard multivitamin, the effects of high-dose single supplements are unpredictable, complex and often harmful. There are optimal levels, and these are often the levels obtained from a healthfu...

Selenium and vitamin E supplementation over recommended dietary intake may raise PC risk
(Oxford University Press) In a large clinical trial testing dietary supplements for prostate cancer prevention, baseline selenium status (measured by toenail selenium concentration), in the absence of supplementation, was not associated with prostate cancer risk. However, when baseline toenail selenium concentrations were high, supplementation with high-dose selenium almost doubled the risk of high-grade prostate cancer risk among older men, according to a new study published Feb. 21 in the Journal of the National Cancer Institute.

Researchers study selenium's effects on horses
(American Society of Animal Science) Selenium is an essential part of the equine diet. Some horses do not get enough selenium because they graze on forages in areas with low selenium in the soil. Researchers at the University of Kentucky and Alltech are curious whether selenium levels affect how horses respond to vaccines. (Source: EurekAlert! - Medicine and Health)
