Selenium is an essential trace element for animals and its role in the chemistry of life relies
on a unique functional group: the selenol (–SeH) group. The selenol group participates in …

As an essential micronutrient, selenium (Se) exerts its biological function as a catalytic entity
in a variety of enzymes. From a toxicological perspective, however, Se can become …

Heme biosynthesis and iron-sulfur cluster (ISC) biogenesis are two major mammalian
metabolic pathways that require iron. It has long been known that these two pathways …

The present study investigated the effects of quercetin in the impairment of memory and
