Reactive oxygen species (ROS) are a chemically defined group of reactive molecules
derived from molecular oxygen. ROS are involved in a plethora of processes in cells in all …

Hydrogen peroxide emerged as major redox metabolite operative in redox sensing,
signaling and redox regulation. Generation, transport and capture of H 2 O 2 in biological …

The concept of cell signaling in the context of nonenzyme-assisted protein modifications by
reactive electrophilic and oxidative species, broadly known as redox signaling, is a uniquely …

Oxygen is a natural acceptor of electrons in the respiratory pathway of aerobic organisms
and in many other biochemical reactions. Aerobic metabolism is always associated with the …

The regulatory mechanisms by which hydrogen peroxide (H 2 O 2) modulates the activity of
transcription factors in bacteria (OxyR and PerR), lower eukaryotes (Yap1, Maf1, Hsf1 and …

Hydrogen peroxide, the nonradical 2-electron reduction product of oxygen, is a normal
aerobic metabolite occurring at about 10 nm intracellular concentration. In liver, it is …

Abstract Background Hydrogen peroxide (H 2 O 2) is an important signaling compound that
has recently been identified as a new substrate for several members of the aquaporin …

Abstract Dietary selenium (] Se), mainly through its incorporation into selenoproteins, plays
an important role in inflammation and immunity. Adequate levels of Se are important for …

The concentration of hydrogen peroxide (H 2 O 2) in blood and plasma is a measurement
that has often been made, but the absolute values remain unsettled due the great variability …

The first suggestion that physical exercise results in free radical-mediated damage to tissues
appeared in 1978, and the past three decades have resulted in a large growth of knowledge …
