Recent Development of the Molecular and Cellular Mechanisms of Hydrogen Sulfide Gasotransmitter

Antioxidants, 2022
Hydrogen sulfide has been recently identified as the third biological gasotransmitter, along with the more well studied nitric oxide (NO) and carbon monoxide (CO). Intensive studies on its potential as a therapeutic agent for cardiovascular, inflammatory,

Juggling with reactive oxygen species and antioxidant defense system – A coping mechanism under salt stress

Plant Stress, 2022
Even under optimal conditions many metabolic processes produce ROS like superoxide anion (O2.-), hydrogen peroxide (H2O2) and hydroxyl radicals (OH⋅), particularly in chloroplast and mitochondria.

Sulfur-Containing Persistent Free Radicals and Reactive Species on Photoaged Microplastics: Identification and the Formation Mechanism

, 2023
The elemental composition may affect the persistent free radical (PFR) and reactive species (RS) formation associated with photoaging microplastics; however, a relevant study is still lacking.

Synthesis of Sulfides and Persulfides Is Not Impeded by Disruption of Three Canonical Enzymes in Sulfur Metabolism

Antioxidants, 2023
Reactive sulfur species, or persulfides and polysulfides, such as cysteine hydropersulfide and glutathione persulfide, are endogenously produced in abundance in both prokaryotes and eukaryotes, including mammals.

Bunsen section thermodynamic model for hydrogen production by the sulfur-Iodine cycle [PDF]

, 2009
A model for the Bunsen section of the Sulfur – Iodine thermo-chemical cycle is proposed, where sulfur dioxide reacts with excess water and iodine to produce two demixing liquid aqueous phases (H2SO4 rich and HI rich) in equilibrium.

The Reactive Sulfur Species Concept: 15 Years On [PDF]

, 2018
Fifteen years ago, in 2001, the concept of “Reactive Sulfur Species” or RSS was advocated as a working hypothesis. Since then various organic as well as inorganic RSS have attracted considerable interest and stimulated many new and often unexpected ...
