Hydrogen sulfide exists widely in mammalian tissues and plays a vital role in physiological and pathophysiological processes. However, striking differences with orders of magnitude were observed for the detected hydrogen sulfide concentrations in biological matrices among different measurements in literature, which lead to the uncertainty for examination the biological relevance of hydrogen sul...

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...

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 ...

      Background & Aims: Hydrogen sulfide due to cytoprotective effects can be used in prevention and treatment of many disorders. The effects of hydrogen sulfide onhormonal system in rat kidneys with cisplatin (CP) nephrotoxicity are unknown. The purpose of the experiments was to survey the effects of hydrogen sulfide on rat kidneys hormonal system with cisplatin nephrotoxicity. Ma...

  Heavy metals are the cause of major abiotic stresses in plants and a principal contributor to environmental pollution in recent decades. This study investigated the effects of exogenous hydrogen sulfide on the ascorbate-glutathione cycle in the leaves of coriander seedlings under copper stress. Results showed that copper stress not only reduced APX and GR activities but also decreas...

Hydrogen sulfide is an essential gasotransmitter associated with numerous pathologies. We assert that hydrogen sulfide plays an important role in regulating macrophage function in response to subsequent inflammatory stimuli, promoting clearance of leukocyte infiltrate and reducing TNF-α levels in vivo following zymosan-challenge. We describe two distinct methods of measuring leukocyte hydrogen ...

The measurement of sulfide, especially hydrogen sulfide, has held the attention of the analytical community due to its unique physiological and pathophysiological roles in biological systems. Electrochemical detection offers a rapid, highly sensitive, affordable, simple, and real-time technique to measure hydrogen sulfide concentration, which has been a well-documented and reliable method. This...

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 single dose of cp (6 mg kg-1) and nep...

Objective(s): It has been demonstrated that hydrogen sulfide plays a vital role in physiological and pathological processes such as regulating inflammation, oxidative stress, and vessel relaxation. The aim of the study was to explore the effect of hydrogen sulfide on angiogenesis in the ischemic adductor muscles of type 2 diabetic db/db mice and ischemic diabetic wound...
