Gas Hazard Induced by Methane and Hydrogen Sulfide Seepage in the NW Peloponnesus Petroliferous Basin (Greece)

Hydrogen sulfide ameliorates the kidney dysfunction and damage in cisplatin-induced nephrotoxicity in rat

Hydrogen Sulfide (H2S) prevents and treats a variety of disorders via its cytoprotective effects. However, the effects of H2S on rats with cisplatin (CP) nephrotoxicity are unclear. The aim was to study the effects of H2S on rats with CP nephrotoxicity. Thirty male Sprague-Dawley rats were divided into three groups: control group, nephrotoxic group received sing...

Gas signaling molecule hydrogen sulfide attenuates doxorubicin-induced dilated cardiomyopathy

Increasing evidence has revealed that hydrogen sulfide (H2S) has beneficial effects in the treatment of various cardiovascular diseases. However, whether H2S can attenuate the development of dilated cardiomyopathy (DCM) remains unclear. In this study, we generated a rat model of DCM induced by doxorubicin and investigated the protective effects of H2S against DCM. Cardiac structure and function...

Hydrogen Sulfide Gas Levels Post Feeding

Oceanic methane seepage during warming

Atmospheric levels of methane, a potent greenhouse gas, vary greatly in the climate record and are usually thought to be due to emissions from continental wetlands. However, Tessa Hill et al. report that methane was released into the atmosphere from the oceans during the period of global warming associated with the most recent deglaciation. The results suggest that, at times, much more methane ...

Methane seepage and its relation to slumping and gas hydrate at the Hikurangi margin, New Zealand

Dissolved methane and high resolution bathymetry surveys were conducted over the Rock Garden region of Ritchie Ridge, along the Hikurangi margin, eastern New Zealand. Multibeam bathymetry reveals two prominent, northeast trending ridges, parallel to subduction along the margin, that are steep sided and extensively slumped. Elevated concentrations of methane (up to 10 nM, 10× background) within ...
