1. By maintaining the pH of the gastric contents above 7, a series of nonproteolytic enzymes have been demonstrated to be present in gastric juice. These include lactic dehydrogenase, isocitric dehydrogenase, leucine aminopeptidase, alkaline phosphatase, glutamic oxalocetic transaminase, glutamic pyruvic...

LPR events are rare in an asymptomatic population. One or more LPR events should be considered abnormal in patients with LPR symptoms regardless of whether there is a positive DeMeester score. Introduction The direct effects of refluxed gastric contents on the upper aerodigestive tract cause laryngopha...
which derive from distinct stem cells. In this context, C cells constitute a relatively small proportion of the parenchymal cell population and are typically located along the central regions of the two lobes, in the middle thirds, interspersed among thyroid hormone-producing follicular cells....
Table 1. Effect of different concentrations of indomethacin on human gastric cancer cell proliferation and viability AGS cells were treated with indomethacin at the indicated doses for 24 h. Cells were analyzed for DNA content and cellular dehydrogenase activity as described under “Experimental procedur...
Vitamin D is produced in the skin upon exposure to ultraviolet light (sunlight). It is activated in two steps to function as a key regulator of mineral ion homeostasis. Vitamin D becomes bound to the vitamin D binding protein, DBP, in the circulation and
A. Saghai Maroof1* Abstract Background: Low phytic acid (lpa) crops are potentially eco-friendly alternative to conventional normal phytic acid (PA) crops, improving mineral bioavailability in monogastric animals as well as decreasing phosphate pollution. The lpa crops developed to date carry ...
Abnormalities in pyloric development or in contractile function of the pylorus cause reflux of duodenal contents into the stomach and increase the risk of gastric metaplasia and cancer. Abnormalities of the pyloric region are also linked to congenital defects such as the relatively common neonatal hyper...
Briefly explain the process of digestion. Why is it necessary for the stomach contents to be acidic? How does the stomach protect itself from digestion? What separates the stomach from the duodenum? a. Describe the process of gastric digestion. b. Wha...
etc. produced by the intestinal bacteria makes pH in the intestines into acid, resulting in promoting a peristalsis of the intestines and improving the digestion. In addition, the exterior germs which do not die by gastric acid or bile and the like can not be settled because the intestinal ge...
