Interactions of memantine and rivastigmine with graphene oxide nanocarrier and beta-amyloid protein using molecular docking and in-silico methods.

Alzheimer's disease is characterized by the accumulation of beta-amyloid plaques and neurofibrillary tangles. Effective therapeutic strategies involve inhibiting the formation of beta-amyloid aggregates and destabilizing existing ones. A significant challenge in current treatments is the inability of therapeutic agents to cross the blood-brain barrier, a limitation addressed by employing drug nanocarriers.

Nrf2 Mediates Effect of Resveratrol in Ischemia-reperfusion Injury.

Ischemia-Reperfusion Injury (IRI) is a paradoxical phenomenon where removing the source of injury can cause additional damage. Ischemia reduces ATP production and intracellular pH, reducing oxidative reactions, increasing lactic acid release, and activating anaerobic metabolism. Reperfusion restores aerobic respiration and increases ROS production, leading to malfunction of transmembrane transport, activation of proteases, DNA dissolution, and protein denaturation, leading to apoptotic cell death.
