However, poorly communicated information on these websites may result in unintended adverse health outcomes. OBJECTIVE This study examined whether: (1) Internet-based cancer risk assessment tools use risk(More)

The increase in gastrin caused by the gastric proton pump inhibitor, omeprazole, is presumably secondary to inhibition of gastric acid secretion but could also be due to a direct effect on the gastrin cells. This experiment was designed to determine whether gastrin elevations caused by omeprazole are related to intragastric pH. We studied gastrin release(More)
Omeprazole is a potent inhibitor of gastric acid secretion (GAS). It has a unique mechanism of action within the parietal cell where it inhibits (H+-K+) ATPase in secretory membranes. The inhibitory effect of omeprazole was measured over a 24-hr period in the dog. Seventy-five minutes after start of pentagastrin-stimulated GAS, placebo or omeprazole(More)
