The pH scale is frequently used to describe the acidity of a solution: {eq}pH = -log[H+] {/eq} In this equation, "pH" is simply defined as meaning the negative log of the concentration of hydrogen ions (protons) in moles/L (molarity). ...
The pH inside cells (6.8) and the pH in the blood (7.4) are both very close to neutral.However, the environment in the stomach is highly acidic, with a pH of 1 to 2. So how do the cells of the stomach survive in such an acidic environment? How do they homeostatically maintain ...

Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain
it illustrates ways in which people with psychosis can develop and maintain psychological resilience to mental health problems of which having suicidal experiences are frequent. Understanding resilience is an expanding area in suicide research [37,38,45]. Second, it provides a basis for developing eff...
