Arterial baroreflex is a general mechanism maintaining cardiovascular homeostasis; its sensitivity is reduced in vascular calcification (VC). Hydrogen sulfide (H2S) treatment facilitates baroreflexive sensitivity in normal and hypertensive rats. Here, we aimed to detect the effect of H2S on baroreflexive sensitivity in rats with VC. The rat VC model was induced by vitamin D3 plus nicotine for 4...

Aims. We object to elucidate that protective effect of H2S on endothelium is mediated by downregulating BMP4 (bone morphogenetic protein 4)/cyclooxygenase- (COX-) 2 pathway in rats with hypertension. Methods and Results. The hypertensive rat model induced by two-kidney one-clip (2K1C) model was used. Exogenous NaHS administration (56 μmol/kg/day, intraperitoneally once a day) reduced mean arter...

OBJECTIVE To compare the clinical outcome of arthroscopic surgery for femoroacetabular impingement (FAI) between athlete and nonathlete patients. DESIGN Retrospective case-control study. Level of Evidence III. PATIENTS AND METHODS Seventy-four patients who underwent arthroscopic FAI correction from March 2009 to April 2012 were enrolled in this study. The patients were divided into 2 groups...

Treatment of non-healing burn injuries is a major challenge for the current scientific research. Hydrogen sulfide (H2S) an endogenous gasotransmitter, which regulates redox homeostasis and cytoprotection during pathophysiological conditions. Similarly, heat shock proteins (HSPs) are molecular chaperones, also confer wound repair process. Notably, role H2S as regulator HSPs healing still elusive...

Hydrogen sulfide (H2S) takes part in a diverse range of intracellular pathways and hss physical and pathological properties in vitro and in vivo. However, the effects of H2S on cancer are controversial and remain unclear. The present study investigates the effects of H2S on liver cancer progression via activating NF-κB pathway in PLC/PRF/5 hepatoma cells. PLC/PRF/5 hepatoma cells were pretreate...

objective(s):  this study was undertaken to investigate the protective effects of vitamin b6, cofactor for cystathionine-γ lyase and cystathionine-β synthase (producers of h2s), alone and in combination with l-cysteine, h2s precursor, on indomethacin-, and ethanol-induced gastric lesions in male nmri mice. materials and methods: fasted male nmri mice were randomly assigned into 12 groups (7 in ...

Hydrogen sulfide (H(2)S) is a recently identified endogenous vasodilator in mammals. In steelhead/rainbow trout (Oncorhynchus mykiss, Osteichthyes), H(2)S produces both dose-dependent dilation and a unique dose-dependent constriction. In this study, we examined H(2)S vasoactivity in all vertebrate classes to determine whether H(2)S is universally vasoactive and to identify phylogenetic and/or e...

Many surgical techniques have been described for femoroacetabular impingement (FAI) surgery to help with improvement of pain and function in symptomatic patients. The aim of this study was to evaluate early patient reported outcomes and complications using combined hip arthroscopy and limited open osteochondroplasty technique. We retrospectively analysed 27 hips in 26 patients. Outcomes were as...

Hydrogen sulfide (H(2)S) has been proposed as a novel neuromodulator, which plays critical roles in the central nervous system affecting both neurons and glial cells. However, its relationship with neurodegenerative diseases is unexplored. The present study was undertaken to investigate the effects of H(2)S on cell injury induced by rotenone, a commonly used toxin in establishing in vivo and in...

Hydrogen sulfide (H2S) is an endogenous gasotransmitter in human physiology and inflammatory disease, however, with limited knowledge of how signal transduction pathways are involved in immune cells. To examine the effects of sulfide on relevant intracellular signaling in human peripheral blood mononuclear cells (PBMCs), we stimulated healthy donor PBMCs with sodium hydrosulfide (NaHS, 1-1000μM...
