The summer of hydrogen sulfide: highlights from two international conferences
A great deal of interest has been paid recently to the hydrogen sulfide, the newest member of the gasotransmitter family. With the growing interest in the biology of H2S, the need for meetings and conferences dedicated solely to the field of H2S has also grown. In 2009, scientist from around the world met in Shanghai, China for the first time to discuss the physiological relevance of H2S. In 20...
متن کاملHydrogen sulfide improves vessel formation of the ischemic adductor muscle and wound healing in diabetic db/db mice
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...
متن کاملEffects of Hydrogen Sulfide on Cold-Induced Oxidative Damage in Cucumis sativus L.
One of the major abiotic stresses limiting the productivity and the geographical distribution of many important crops is low temperature. Hydrogen sulfide (H2S) is an important signaling molecule involved in several stress-resistance processes such as drought, salinity and heavy metal stresses in plants. The aim of this study was to investigate the effects of exogenous H2S...
متن کاملVasodilatory effects of nitric oxide, hydrogen sulfide and sulfur dioxide in rats: Time-dependent interaction study
The vasodilator response of nitric oxide (NO), hydrogen sulfide (H2S) and sulfur dioxide (SO2) were studied todetermine the significance of the actions and interactions of these gasotransmitters for controlling aortic tone in rats. The isometric tension of five separate sets of experiments was recorded. Sodium nitroprusside (SNP; NO donor), sodium disulphide (Na2S; H2S donor), SO2 derivatives a...
متن کاملRedox biology of hydrogen sulfide: Implications for physiology, pathophysiology, and pharmacology☆
Hydrogen sulfide (H2S) has emerged as a critical mediator of multiple physiological processes in mammalian systems. The pathways involved in the production, consumption, and mechanism of action of H2S appear to be sensitive to alterations in the cellular redox state and O2 tension. Indeed, the catabolism of H2S through a putative oxidation pathway, the sulfide quinone oxido-reductase system, is...
