Oxidative stress in skin plays a major role in the aging process. This is true for intrinsic aging
and even more for extrinsic aging. Although the results are quite different in dermis and …

Abiotic stress is one of the main threats affecting crop growth and production. An
understanding of the molecular mechanisms that underpin plant responses against …

Reactive oxygen species (ROS) are known mediators of intracellular signaling cascades.
Excessive production of ROS may, however, lead to oxidative stress, loss of cell function …

Nitric oxide in plants may originate endogenously or come from surrounding atmosphere
and soil. Interestingly, this gaseous free radical is far from having a constant level and varies …

Providing a comprehensive review of reactions of oxidation for different classes of organic
compounds and polymers, and biological processes mediated by free radicals, Oxidation …

The present study investigates the possible regulatory role of exogenous nitric oxide (NO) in
mitigating oxidative stress in wheat seedlings exposed to arsenic (As). Seedlings were …

In recent studies we demonstrated that systemic levels of protein-bound nitrotyrosine
(NO2Tyr) and myeloperoxidase (MPO), a protein that catalyzes generation of nitrating …

Myeloperoxidase (MPO) is an abundant mammalian phagocyte hemoprotein thought to
primarily mediate host defense reactions. Although its microbicidal functions are well …

Aged mammalian tissues show a decreased capacity to produce ATP by oxidative
phosphorylation due to dysfunctional mitochondria. The mitochondrial content of rat brain …

Protein S‐glutathiolation, the reversible covalent addition of glutathione to cysteine residues
on target proteins, is emerging as a candidate mechanism by which both changes in the …
