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) have been linked to an increased risk of chronic kidney disease. PPIs have previously been linked to a kidney disorder called acute interstitial nephritis. These heartburn drugs may also increase your risk of fractures, serious infections, heart attack and nutrient deficiencies.
