Redox balance maintaining is a prerequisite for normal cardiomyocytes metabolism. Reperfusion injury of the heart characterized by an explosive increase in ROS generation, cell membranes damage, dysfunction proteins, development muscle contracture etc. It was shown that hydrogen sulfide (H2S) and precursor its synthesis amino acid L-cysteine provided cardioprotective effect against ischemiarepe...

H(2)S generated by the enzyme cystathionine-γ-lyase (CSE) has been implicated in O(2) sensing by the carotid body. The objectives of the present study were to determine whether glomus cells, the primary site of hypoxic sensing in the carotid body, generate H(2)S in an O(2)-sensitive manner and whether endogenous H(2)S is required for O(2) sensing by glomus cells. Experiments were performed on g...

Lipopolysaccharide can induce myocardial cell injury, which has been widely used in the preparation of septic cardiomyopathy models. We herein aimed to evaluate protective effects sodium hydrosulfide against oxidative stress and endoplasmic reticulum on model explore whether protein kinase RNA-like kinase-eukaryotic initiation factor 2 alpha signaling pathways was involved. The sepsis induced e...

Annotation. Vitamin D and hydrogen sulfide (H2S) belong to pleitropic regulators, which are involved in the control of many cellular functions biochemical processes, determine adaptive potential cardiovascular system. The relationship between vitamin H2S system is not fully investigated. aim study was evaluate effect active form - calcitriol (1,25 (OH)2D3) on morphological state thoracic aorta ...

The finding that liver necrosis caused by the environmental glutathione (GSH)-depleting chemical, bromobenzene (BB) is associated with marked impairment in O- and S-methylation of BB metabolites in Syrian hamsters raises questions concerning the role of methyl deficiency in BB toxicity. N-Acetylmethionine (NAM) has proven to be an effective antidote against BB toxicity when given after liver GS...

Introduction: Recently, hydrogen sulfide has been introduced as the third gas that acts as a transmitter. It has many physiological and pharmacological roles in the human body. The aim of the present study was to investigate the effect of exogenously administered and endogenously produced H2S on the basal and distention-induced gastric acid secretion in rats. Methods: Forty-nine male Wistar...

To study the fate of L-cysteine and amino acid homeostasis in liver after the inhibition of the trans-sulfuration pathway, rats were treated with propargylglycine (PPG). At 4 h after the administration of PPG, liver cystathionase (EC 4.4.1.1) activity was undetectable, L-cystathionine levels were significantly higher, L-cysteine was unchanged and GSH concentration was significantly lower than v...
