The release and physiological actions of secretin on pancreatic exocrine secretion and gastric secretion of acid and motility are regulated by neuro-hormonal control. The release of secretin by duodenal acidification is mediated by a secretin releasing peptide (SRP). The release and action of SRP are neurally mediated depending on vagal afferent pathway. SRP activity in acid perfusate of the du...

background and aim: oral mucosal lesions have various prevalence rates among different populations. few studies have evaluated the frequency of oral mucosal lesions in iranian population. this study aimed to determine the frequency of oral mucosal lesions and the related factors.                        materials and methods: this descriptive study was conducted based on the data in the archives...

We experimentally acidified three low alkalinity first-order streams in forested catchments in Maine, USA. We evaluated water samples from a reference site above the point of hydrochloric acid addition and from two or three sites located 16 to 94 m downstream. Neutralization included protonation of weak acids, adsorption of sulfate, and ion exchange of base cations and aluminum (Al) for protons...
