WebbFör 1 dag sedan · G. lucidum protects the liver through a broad range of mechanisms that include the modulation of liver Phase I and II enzymes, the suppression of β-glucuronidase, antifibrotic and antiviral actions, the regulation of the production of nitric oxide (NO), the maintenance of hepatocellular calcium homeostasis, immunomodulatory activity, and … WebbThe action potential is a sudden and transient depolarization of the membrane. The cells that initiate action potentials are called ‘excitable cells’. Action potentials can have different shapes; i.e. different amplitudes and durations.
