objective(s): prostaglandins have been shown to mediate the gastro-protective effect of sodium hydrosulfide (nahs) but effect of nahs on mrna expression of prostaglandin e2 receptors (ep1, 3-4; eps) has not been investigated. therefore, this study designed to evaluate the effect of nahs on mrna expression of eps receptors in response to mucosal acidification and distention-induced gastric acid ...

Heavy metals pollution is one of the key environmental problems. In this research, the effect of seed priming with salicylic acid and sodium hydrosulfide was investigated on methionine and arginine amino acids contents and some compounds derived from their metabolism as well as ZmACS6 and ZmSAMD transcripts levels in maize plants under lead stress. For this purpose, maize seeds were soaked in s...

2-Dihydroquinazolin-4(1H)-thiones were prepared in up to excellent yields from 2-aminobenzothioamides and aldehydes. The reaction is carried out in water without the use of any catalyst or promoter. The sulfur-containing substrate can be obtained easily by thiation of the corresponding nitrile by solid sodium hydrosulfide.

Alzheimer's disease (AD) is known to be caused by the accumulation of amyloid-β peptide (Aβ). The accumulation of Aβ has been shown to cause learning and memory impairment in rats, and it has been shown that hydrogen sulfide donors, such as sodium hydrosulfide (NaHS) can attenuate these effects. However, the underlying mechanisms have not yet been fully eludicated. This study was designed to in...
