The effect of lipopolysaccharide (LPS) in gastric protection has not been elucidated, but ATP-sensitive potassium (K(ATP)) channels are known to be involved in gastric defense. We evaluated the effect of LPS administration on indomethacin-induced gastropathy, and the role of K(ATP) channels in this

Potassium-competitive acid blockers (P-CABs) are highly safe and active drugs targeting H+,K+-ATPase to cure acid-related gastric diseases. In this study, we for the first time investigate the interaction mechanism between the protonated form of P-CABs and human H+,K+-ATPase using homology modeling,

As a physiological phenomenon, acid secretion from the stomach was known already at least in the 17th century. But its mechanism was elucidated in more recent times only. At the end of the 20th century, gastric H(+)/K(+)-ATPase in the parietal cells was found to be responsible for a final step of

Seven kinds of Chinese traditional medicines, including laoniankechuan tablet, fufangbanxia tablet, weitongning tablet, quanshen tablet, shengshijiangtang capsule, xiasangju particle, and American yangshen tablet, were digested with HNO3-HClO4 mixed acid. The fourteen trace elements, including

The dramatic success of pharmacological acid suppression in healing peptic ulcers and managing patients with gastroesophageal reflux disease (GERD) has been reflected in the virtual abolition of elective surgery for ulcer disease, a reduction in nonsteroidal anti-inflammatory drug (NSAID)-associated

Potassium-competitive acid blockers (P-CABs), such as vonoprazan, represent a novel and heterogeneous class of drugs that competitively block the potassium binding site of gastric H⁺/K⁺ ATPase, thus potentially overcoming the limitations of proton-pump inhibitors. Different

OBJECTIVE Sildenafil is a selective inhibitor of cGMP-specific phosphodiesterase. Sildenafil, acting via NO-dependent mechanisms, prevents indomethacin-induced gastropathy. Activation of ATP-sensitive potassium channels (K(ATP)) is involved in gastric defence. Our objective was to evaluate the role

Nitric oxide (NO) and carbon monoxide (CO) synthesized from L-arginine by NO synthase and from heme by heme oxygenase, respectively, are the well-known neurotransmitters and are also involved in the regulation of vascular tone. Recent studies suggest that hydrogen sulfide (H(2)S) is the third
