Exposure of biological molecules to oxidants is inevitable and therefore commonplace.
Oxidative stress in cells arises from both external agents and endogenous processes that …

Nitric oxide (NO) is a small free radical with critical signaling roles in physiology and
pathophysiology. The generation of sufficient NO levels to regulate the resistance of the …

Nitric oxide (NO) signalling has pleiotropic roles in biology and a crucial function in
cardiovascular homeostasis. Tremendous knowledge has been accumulated on the …

Over the last decade, a dual character of cell response to oxidative stress, eustress versus
distress, has become increasingly recognized. A growing body of evidence indicates that …

Reactive oxygen, nitrogen, and sulfur species, referred to as ROS, RNS, and RSS,
respectively, are produced during normal cell function and in response to various stimuli. An …

Plant growth promoting rhizobacteria (PGPR) are diverse, naturally occurring bacteria that
establish a close association with plant roots and promote the growth and immunity of …

Glutathione (GSH) is a tripeptide, which has many biological roles including protection
against reactive oxygen and nitrogen species. The primary goal of this paper is to …

The free radicals along with several reactive oxygen species (ROS) and reactive nitrogen
species (RNS) are known to play a dual role in the biological living system which carries a …

Pyrrole is a heterocyclic ring template with multiple pharmacophores that provides a way for
the generation of library of enormous lead molecules. Owing to its vast pharmacological …

Significance: Protein S-nitrosylation, the oxidative modification of cysteine by nitric oxide
(NO) to form protein S-nitrosothiols (SNOs), mediates redox-based signaling that conveys, in …
