Selenium is a trace and essential micronutrient for the health of humans, animals, and
microorganisms. Recently, selenium nanoparticles (SeNPs) attracted the interest of many …

The biological activity of selenium is dependent upon its speciation. We aim to integrate
selenium speciation and metabolism into a discussion of the mechanisms by which …

The trace element selenium is of high importance for many of the body's regulatory and
metabolic functions. Balanced selenium levels are essential, whereas dysregulation can …

Reductive stress (RS) is the counterpart oxidative stress (OS), and can occur in response to
conditions that shift the redox balance of important biological redox couples, such as the …

Although oxidants clearly possess the capacity to behave in a random and destructive
fashion, growing evidence suggests that in many instances the production of reactive …

Mitochondrial dysfunction and oxidative damage represent important pathological
mechanisms of myocardial ischemia-reperfusion injury (MI/RI). Searching for potential …

Selenium (Se) is an essential trace element, and its low status in humans has been linked to
increased risk of various diseases, such as cancer and heart disease. In recent years, Se …

Reactive oxygen species (ROS) are derived from cellular oxygen metabolism and from
exogenous sources. An excess of ROS results in oxidative stress and may eventually cause …

Selenoproteins are proteins containing selenium in the form of the 21st amino acid,
selenocysteine. Members of this protein family have many diverse functions, but their …

The world's rare selenium resources need to be managed carefully. Selenium is extracted
as a by-product of copper mining and there are no deposits that can be mined for selenium …
