Hydrogen Sulfide Signaling in Plants

Antioxidants & Redox Signaling, 2023
Significance: Hydrogen sulfide (H2S) is a multitasking potent regulator that facilitates plant growth, development, and responses to environmental stimuli. Recent Advances: The important beneficial effects of H2S in various aspects of plant physiology aroused the interest of this chemical for agriculture.

Hydrogen Sulfide and Neuroinflammation

2015
The innate and adaptive immune system plays an important role in diverse forms of central nervous system (CNS) pathologies including neurodegenerative diseases and peripheral nerve injury. Evidence for an innate inflammatory response in Alzheimer's disease (AD) was described 20 years ago, and subsequent studies have documented roles of inflammation in ...

Hydrogen sulfide as a source of hydrogen

International Journal of Hydrogen Energy, 1984
Abstract We suggest that hydrogen sulfide (that which is removed from fossil fuels as an unwanted waste product, as well as that which might be sought as a mineral in its own right), should be considered as a source of hydrogen. We discuss several techniques by means of which hydrogen sulfide might be thus exploited.

Hydrogen Sulfide Inhalation Injury

Journal of Burn Care & Rehabilitation, 2000
Hydrogen sulfide is a colorless, noxious gas with the distinctive smell of rotten eggs. This compound is a powerful reducing agent that is encountered in a number of industrial processes. When hydrogen sulfide is present, it exposes workers to the potentially lethal effects of the rapid hypoxemia that results from exposure to this agent.

Hydrogen sulfide intoxication

2015
Hydrogen sulfide (H2S) is a hazard primarily in the oil and gas industry, agriculture, sewage and animal waste handling, construction (asphalt operations and disturbing marshy terrain), and other settings where organic material decomposes under reducing conditions, and in geothermal operations.

Hydrogen Sulfide as a Neuromodulator

Molecular Neurobiology, 2002
Hydrogen sulfide (H2S) is a well-known toxic gas with the smell of rotten eggs. Since the first description of the toxicity of H2S in 1713, most studies about H2S have been devoted to its toxic effects. Recently, H2S has been proposed as a physiologically active messenger.

Recovery of hydrogen from hydrogen sulfide with metals or metal sulfides

International Journal of Hydrogen Energy, 1982
Abstract The following two types of reactions were investigated for the recovery of hydrogen from hydrogen sulfide: Type 1 H 2 S → H 2 + S 0 , Type 2 H 2 S + O 2 → H 2 + SO 2 Each type of reaction is constructed by a two-step cycle, in which H 2 S is reacted with metal or metal sulfide and then the resulting sulfide undergoes thermal ...

Chemisorption of hydrogen sulfide on lead sulfide

Russian Journal of Electrochemistry, 2006
The hydrogen sulfide chemisorption on lead sulfide at 22–100°C is studied by static testing in a vacuum and by pulsed chromatography. It is established that H2S is sorbed in reversible and irreversible forms and that the process is accompanied by the sample charging.

Hydrogen Sulfide Oxidation by Sulfide Quinone Oxidoreductase

ChemBioChem, 2020
AbstractHydrogen sulfide (H2S) is an environmental toxin and a heritage of ancient microbial metabolism that has stimulated new interest following its discovery as a neuromodulator. While many physiological responses have been attributed to low H2S levels, higher levels inhibit complex IV in the electron transport chain.

Hydrogen Sulfide and Urogenital Tract

2015
In this chapter the role played by H2S in the physiopathology of urogenital tract revising animal and human data available in the current relevant literature is discussed. H2S pathway has been demonstrated to be involved in the mechanism underlying penile erection in human and experimental animal. Both cystathionine-β synthase (CBS) and cystathionine-γ
