Hydrogen sulfide (H(2)S) is now recognized as an important signaling molecule and has been shown to have vasodilator and cardio-protectant effects. More recently it has been suggested that H(2)S may also act within the brain to reduce blood pressure (BP). In the present study we have demonstrated the presence of the H(2)S-producing enzyme, cystathionine-β-synthase (CBS) in the rostral ventrolat...

Mitochondrial dysfunction plays an important role in the pathogenesis of diaphragm weakness during sepsis. Recently, hydrogen sulfide (H2S), a gaseous transmitter endogenously generated by cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST), is found to improve mitochondrial function. The present study aimed to examine whether H2S synthas...

Hydrogen sulfide (H2S) is a gaseous mediator synthesized in mammalian tissues by three main enzymes—cystathionine-b-synthase (CBS), cystathionine-g-lyase (CSE), and 3-mercaptopyruvatesulfurtransferase—and its levels increase under inflammatory conditions or sepsis. SinceH2S andH2S-releasingmolecules afford inhibitory properties in leukocyte trafficking, we tested whether endogenous annexin A1 (...

BACKGROUND Hydrogen sulfide (H(2)S) displays vasodilative, anti-oxidative, anti-inflammatory and cytoprotective activities. Impaired production of H(2)S contributes to the increased intrahepatic resistance in cirrhotic livers. The study aimed to investigate the roles of H(2)S in carbon tetrachloride (CCl(4))-induced hepatotoxicity, cirrhosis and portal hypertension. METHODS AND FINDINGS Sodiu...

BACKGROUND Femoroacetabular impingement (FAI) is common with an estimated prevalence of 10-15% among young active individuals. The natural history of the disorder is progression to early osteoarthritis. Hip arthroscopy is recommended if conservative treatments fail; however, outcomes are unclear, particularly in highly active populations. AIM To evaluate the functional and vocational outcome ...

Hip arthroscopy has continued to expand its horizons in treating many conditions other than femoroacetabular impingement (FAI). However, the results of hip arthroscopy are known to be poor if the degree of articular cartilage damage is significant. We wanted to assess, whether the procedure might have a role in the management of young and active patients with advanced osteoarthritis (OA) and wh...

BACKGROUND AND PURPOSE Hydrogen sulfide (H2S) is a highly toxic gas for which no effective antidotes exist. It acts, at least in part, by binding to cytochrome c oxidase, causing cellular asphyxiation and anoxia. We investigated the effects of three different ligand forms of cobinamide, a vitamin B12 analog, to reverse sulfide (NaHS) toxicity. METHODS New Zealand white rabbits received a cont...
