Reaction Mechanisms of H2S Oxidation by Naphthoquinones
1,4-naphthoquinones (NQs) catalytically oxidize H2S to per- and polysufides and sulfoxides, reduce oxygen to superoxide and hydrogen peroxide, and can form NQ-SH adducts through Michael addition.

The Reactive Species Interactome in Red Blood Cells: Oxidants, Antioxidants, and Molecular Targets
Beyond their established role as oxygen carriers, red blood cells have recently been found to contribute to systemic NO and sulfide metabolism and act as potent circulating antioxidant cells. Emerging evidence indicates that reactive species derived from

Rhodanese Rdl2 produces reactive sulfur species to protect mitochondria from reactive oxygen species
Mitochondria damage is related to a broad spectrum of pathologies including Alzheimer's, Parkinson's disease, and carcinogenesis. Recently, it has been found that reactive sulfur species (RSS) has a close connection with mitochondrial health.

Potential Role of Sulfur-Containing Antioxidant Systems in Highly Oxidative Environments
All forms of life maintain a reducing environment (homeostasis) within their cells. Perturbations in the normal redox state can lead to an oxidative environment which has deleterious effects, especially in health.

Development of Chemical Tools for Studying Reactive Sulfur Species [PDF]
Hydrogen sulfide (H2S) has recently emerged as an important biological signaling molecule involved in a number of key physiological processes. These observations have generated interest in harnessing H2S as a potential therapeutic agent to treat disease ...

14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

A novel S-sulfhydrated human serum albumin preparation suppresses melanin synthesis
Products of ultraviolet (UV) irradiation such as reactive oxygen species (ROS) and nitric oxide (NO) stimulate melanin synthesis. Reactive sulfur species (RSS) have been shown to have strong ROS and NO scavenging effects. However, the instability and low

Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
