Hydrogen sulfide: an endogenous regulator of the immune system.
Pharmacological Research, 2020 Hydrogen sulfide (H2S) is now recognized as an endogenous signaling gasotransmitter in mammals. It is produced by mammalian cells and tissues by various enzymes - predominantly cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE) and 3 ...

Effects of hydrogen sulfide on mitochondrial function and cellular bioenergetics
Redox Biology, 2020 Hydrogen sulfide (H2S) was once considered to have only toxic properties, until it was discovered to be an endogenous signaling molecule. The effects of H2S are dose dependent, with lower concentrations being beneficial and higher concentrations ...

Pre- and posttreatment with hydrogen sulfide prevents ventilator-induced lung injury by limiting inflammation and oxidation. [PDF]
PLoS ONE, 2017 Although essential in critical care medicine, mechanical ventilation often results in ventilator-induced lung injury. Low concentrations of hydrogen sulfide have been proven to have anti-inflammatory and anti-oxidative effects in the lung.

Characterization of lacustrine iron sulfide particles with proton-induced X-ray emission. [PDF]
, 1992 Black particles, collected by filtration (1.2~pm pore size) from the anoxic waters of a soft-water lake, were examined by a scanning proton microprobe which permitted quantitative elemental analysis by proton-induced X-ray emission (PIXE) and Rutherford ...
