Hydrogen sulfide (H(2)S) is an endogenously generated gaseous transmitter, which has recently been suggested to regulate cardiovascular functions. The present study aims to clarify the mechanisms underlying the cardioprotective effects of H(2)S. Signaling elements were examined in cardiomyocytes cultured under hypoxia/reoxygenation conditions and in a rat(More)
OBJECTIVE To probe the effect of sodium para-aminosalicylate (PAS-Na) on concentration of amino acid neurotransmitters including glutamate (Glu), glutamine (Gln), glycine (Gly) and gamma-aminobutyric acid (GABA) in basal ganglia of subacute manganese (Mn)-exposed rats. METHODS Forty Sprague-Dawley male rats were randomly divided into the control,(More)
Manganese (Mn), an essential trace metal for protein synthesis and particularly neurotransmitter metabolism, preferentially accumulates in basal ganglia. However, excessive Mn accumulation may cause neurotoxicity referred to as manganism. Sodium para-aminosalicylic acid (PAS-Na) has been used to treat manganism with unclear molecular mechanisms. Thus, we(More)
Excessive manganese (Mn) exposure is not only a health risk for occupational workers, but also for the general population. Sodium para-aminosalicylic acid (PAS-Na) has been successfully used in the treatment of manganism, but the involved molecular mechanisms have yet to be determined. The present study aimed to investigate the effects of PAS-Na on(More)
OBJECTIVE To study the effects of deltamethrin (DM) on the permeability of mitochondrial membrane and the expression of cytochrome C in brain tissue of rats. METHODS Wistar rats were randomizedly divided into five groups (including four treated groups and one control group). In the treated groups, DM of 12.5 mg/kg was administered intraperitoneally once(More)
Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide, with a dismal 5-year survival rate less than 15%. The present study aimed to investigate whether AKT inhibition and glucose deprivation could synergistically kill HCC cells and the molecular mechanisms involved. HCC cells were starved in glucose deprivation, and(More)
Manganese (Mn) overexposure induced neurological damages, which could be potentially protected by sodium para-aminosalicylic acid (PAS-Na). In this study, we systematically detected the changes of divalent metal elements in most of the organs and analyzed the distribution of the metals in Mn-exposed rats and the protection by PAS-Na. Sprague Dawley (SD)(More)
—Frequently a group of people jointly decide and authorize a specific person as a representative in some business/poitical occasions, e.g., the board of a company authorizes the chief executive officer to close a multi-billion acquisition deal. In this paper, an integrated proxy multi-signature scheme that allows anonymously vetoable delegation is proposed.(More)
