liver is one of the most important organs needing great concern during the perioperative period. there are a number of different mechanisms that interact with liver cells and might affect their integrity and cell live. though these mechanisms are not all the same, there is a great common point: all affect the metabolic pathways of the liver. ischemia, anesthetic drug effects and other periopera...

Aging is characterized by a progressive loss of tissue integrity and functionality due to disrupted homeostasis. Molecular oxygen pivotal maintain functions, aerobic species have evolved sophisticated sensing system ensure proper supply demand. It not surprising that aberrations in oxygen-associated pathways subvert health promote different aspects aging. In this review, we discuss emerging fin...

This paper investigates the mechanism of water transportation through aquaporin-4(AQP4) of ratbrain cells by means of molecular dynamics simulation with CHARMM software. The AQP4 wasembedded into a bilayer made of Dimystroilphosphatylcholine (DMPC). The results illustrate thatwater molecules move through AQP4's channel with change of orientation of oxygen of eachwater molecule.
