Hydrogen sulfide (H2S) - the third gas of interest for pharmacologists.
Nitric oxide (NO) and carbon monoxide (CO) synthesized from L-arginine by NO synthase and from heme by heme oxygenase, respectively, are the well-known neurotransmitters and are also involved in the regulation of vascular tone. Recent studies suggest that hydrogen sulfide (H(2)S) is the third gaseous mediator in mammals. H(2)S is synthesized from L-cysteine by either cystathionine beta-synthase...
متن کاملHydrogen sulfide (H2S) releasing agents: chemistry and biological applications.
Hydrogen sulfide (H2S) is a newly recognized signaling molecule with very potent cytoprotective actions. The fields of H2S physiology and pharmacology have been rapidly growing in recent years, but a number of fundamental issues must be addressed to advance our understanding of the biology and clinical potential of H2S in the future. Hydrogen sulfide releasing agents (also known as H2S donors) ...
متن کاملHomocysteine, hydrogen sulfide (H2S) and NMDA-receptor in heart failure.
Mitochondrial mechanism of oxidative stress and matrix metalloproteinase (MMP) activation was unclear. Our recent data suggested that MMPs are localized to mitochondria and activated by peroxynitrite, which causes cardiovascular remodeling and failure. Recently, we have demonstrated that elevated levels of homocysteine (Hcy), known as hyperhomocysteinemia (HHcy) increase oxidative stress in the...
متن کاملMicroaeration for hydrogen sulfide removal during anaerobic treatment: a review
High sulfide concentrations in biogas are a major problem associated with the anaerobic treatment of sulfate-rich substrates. It causes the corrosion of concrete and steel, compromises the functions of cogeneration units, produces the emissions of unpleasant odors, and is toxic to humans. Microaeration, i.e. the dosing of small amounts of air (oxygen) into an anaerobic digester, is a highly eff...
متن کاملRemoval of Hydrogen Sulfide from Biogas Using Cow-manure Compost
The two-part objective of this study was to determine currently available H2S removal technologies suitable for use with farm biogas systems, and to test the feasibility of utilizing on-farm cow-manure compost as an H2S adsorption medium. Integrated farm energy systems utilize anaerobic digesters to provide a waste treatment solution, improved nutrient recovery, and energy generation potential ...
