Selenium is an essential trace element that is crucial for cellular antioxidant defense against
reactive oxygen species (ROS). Recently, many selenium-containing compounds have …

Selenium (Se) deficiency can seriously affect the small intestine of swine, and cause
diarrhea in swine. However, the specific mechanism of Se deficiency-induced swine …

Fifteen years ago, in 2001, the concept of “Reactive Sulfur Species” or RSS was advocated
as a working hypothesis. Since then various organic as well as inorganic RSS have …

In this review, a general introduction to biological oxidants (focusing on reactive oxygen
species, ROS) and the biomedical rationale behind the development of materials capable of …

The activity of natural phenols is primarily associated to their antioxidant potential, but is
ultimately expressed in a variety of biological effects. Molecular scaffold manipulation of this …

Taking into account that multidrug resistance (MDR) is the main cause for chemotherapeutic
failure in cancer treatment and as a continuation of our efforts to overcome this problem we …

Various bacteria, including diverse Staphylococci, reduce selenite to yield red selenium
particles with diameters in the high nanometer to low micrometer range. Formation and …

In previous studies, 56 novel selenoesters and one cyclic selenoanhydride with
