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,

Cardiac robustness regulated by reactive sulfur species

Journal of Clinical Biochemistry and Nutrition, 2022
The human myocardium contains robust cells that constantly beat from birth to death without being replaced, even when exposed to various environmental stresses. Myocardial robustness is thought to depend primarily on the strength of the reducing power to protect the heart from oxidative stress.

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.

Reactive sulfur species and their significance in health and disease

Bioscience Reports, 2022
Abstract Reactive sulfur species (RSS) have been recognized in the last two decades as very important molecules in redox regulation. They are involved in metabolic processes and, in this way, they are responsible for maintenance of health.

Diverse Possibilities of Si-Based Agent, a Unique New Antioxidant

Antioxidants, 2023
Antioxidant therapy is an effective approach for treating diseases in which oxidative stress is involved in the onset of symptoms. This approach aims to rapidly replenish the antioxidant substances in the body when they are depleted due to excess ...

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.

Sulfur ligated oxoiron(IV) centre in fenton-like reaction: Theoretical postulation and experimental verification

Catalysis Communications, 2022
The intermediate FeIVO in circumneutral Fenton-like reactions is critical in selective oxidations. However, the inferior electron donation of ligands renders the reactivity of oxoiron(IV) cores.
