Are Reactive Sulfur Species the New Reactive Oxygen Species?
Antioxidants & Redox Signaling, 2020Significance: Oxidative stress in moderation positively affects homeostasis through signaling, while in excess it is associated with adverse health outcomes. Both activities are generally attributed to reactive oxygen species (ROS); hydrogen peroxide as the signal, and cysteines on regulatory proteins as the target.

Enols and Other Reactive Species
Science, 1991Rapid advances in the chemistry of enols and other reactive species have been made possible recently by the development of methods for generating these short-lived substances in solution under conditions where they can be observed directly and their reactions can be monitored accurately.

Hydrogen sulfide, reactive sulfur species and coping with reactive oxygen species
Free Radical Biology and Medicine, 2019Life began in a ferruginous (anoxic and Fe2+ dominated) world around 3.8 billion years ago (bya). Hydrogen sulfide (H2S) and other sulfur molecules from hydrothermal vents and other fissures provided many key necessities for life's origin including catalytic platforms (primordial enzymes) that also served as primitive boundaries (cell walls ...

Ezetimibe and Reactive Oxygen Species
Current Vascular Pharmacology, 2011Ezetimibe is a potent inhibitor of cholesterol absorption that has been approved for the treatment of hypercholesterolemia. Statin, 3-hydroxy-3 methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, is an inhibitor of cholesterol synthesis. Statin is the first-choice drug to reduce low-density lipoprotein (LDL)-cholesterol for patients with ...

Reactive Oxygen Species and Reactive Nitrogen Species in Epigenetic Modifications
2014For the normal homeostasis of a cell, there must be a balance between radical oxygen species/radical nitrogen species (ROS/RNS) production and the neutralization of these species by antioxidant scavenging. In times of stress, this balance is not maintained, and the result is oxidative stress.

Glucose and reactive oxygen species
Current Opinion in Clinical Nutrition and Metabolic Care, 2002This review aims at presenting new concepts of glucose-induced damage in diabetes via an increased production of oxygen free radicals.Reactive oxygen species modulate various biological functions by stimulating transduction signals, some of which are involved in diabetes pathogenesis and complications.Diabetes is characterized by high glucose ...

Reactive oxidant species in asthma
Current Opinion in Pulmonary Medicine, 2006This overview summarizes some recent studies on the balance of oxidants to antioxidants in patients with asthma. The aim of the review is to compare studies on the changes in oxidants/antioxidants in stable asthma or in acute exacerbation of asthma.Our review of the recent literature in this field seems to indicate conflicting findings.

Imaging of Intracellular Reactive Nitrogen Species and Reactive Sulfur Species
2020This chapter summarizes representative small-molecule fluorescent probes for reactive nitrogen species and reactive sulfur species in living cells. The design and response mechanisms of the probes are described in detail. Probes that have not been applied in living cell analysis are not included.

Reactive oxygen species, reactive nitrogen species and redox signalling
2016This chapter explains our current understanding of how reactive oxygen species (ROS) and reactive nitrogen species (RNS) are generated and perceived, and how they propagate their messages. It argues that the main components involved here include those used in phosphorylation and cyclic nucleotides.

Journal of Contaminant Hydrology, 2017
The activation of peroxymonosulfate by iron (II), iron (III), and iron (III)-EDTA for in situ chemical oxidation (ISCO) was compared using nitrobenzene as a hydroxyl radical probe, anisole as a hydroxyl radical+sulfate radical probe, and hexachloroethane as a reductant+nucleophile probe. In addition, activated peroxymonosulfate was investigated for the
