Web7 jun. 2024 · Lithocap Capsule. Although lithium has been used for over 50 years in treatment of bipolar disorder, the mechanism of action is still unknown. Lithium's therapeutic action may be due to a number of effects, ranging from inhibition of enzymes such as glycogen synthase kinase 3, inositol phosphatases, or modulation of glutamate receptors. WebLithocaps are subsurface, broadly stratabound alteration domains that are laterally and vertically extensive. They form when acidic magmatic-hydrothermal fluids react with wallrocks during ascent towards the paleosurface. Although lithocaps typically have steeply-dipping structural roots, there is a significant component of lateral fluid flow involved in … dji avata drone pro-view
