There's Life After Radiation for Brain Cells. Johns Hopkins researchers suggest neural stem cells may regenerate after anti-cancer treatment. Release Date: August 12, 2013. Scientists have long believed that healthy brain cells, once damaged by radiation designed to kill brain tumors, cannot regenerate.
The key player in acid secretion is a H+/K+ ATPase or proton pump located in the cannalicular membrane. 1  This ATPase is magnesium-dependent, and not inhibitable by ouabain. The current model for explaining acid secretion is as follows: 2  Hydrogen ions are generated within the parietal cell from dissociation of water.
Proton pump inhibitors (PPIs) suppress the production of stomach acid and work by inhibiting the molecule in the stomach glands that is responsible for acid secretion (the gastric acid pump). Recent guidelines indicate that PPIs should be the first drug treatment, because they are more effective than H2 blockers.
