Classically, superoxide anion O2•− and reactive oxygen species ROS play a dual role. At
the physiological balance level, they are a by-product of O2 reduction, necessary for cell …

Increasing numbers of individuals suffer from neurodegenerative diseases, which are
characterized by progressive loss of neurons. Oxidative stress, in particular, the …

Extensive research has found strongly increased generation of reactive oxygen species, free
radicals, and reactive nitrogen species during acute physical exercise that can lead to …

The Raman spectrum of living cells and microorganisms contains highly specific fingerprint‐
like signatures, useful in unequivocally identifying different species and interpreting …

Hypertension is a highly prevalent condition with numerous health risks, and the incidence
of hypertension is greatest among older adults. Traditional discussions of hypertension have …

Oxidative stress has been proven to be related to the onset of a large number of health
disorders. This chemical stress is triggered by an excess of free radicals, which are …

In this review, primary attention is given to the antioxidant (and prooxidant) activity of
polyphenols arising from their interactions with iron both in vitro and in vivo. In addition, an …

Abstract Antigen-specific CD8+ T-cell tolerance, induced by myeloid-derived suppressor
cells (MDSCs), is one of the main mechanisms of tumor escape. Using in vivo models, we …

Myeloid-derived suppressor cells (MDSCs) are a well-defined population of cells that
accumulate in the tissue of tumor-bearing animals and are known to inhibit immune …

The roles of superoxide (O2•−), peroxynitrite, and carbon dioxide in the oxidative chemistry
of nitric oxide (NO) are reviewed. The formation of peroxynitrite from NO and O2•− is …
