Mechanisms of hemodynamic adaptation and associated changes in oxygen metabolism after liver resection and the effect of mechanical portal blood flow reduction were assessed. WebNicotinamide mononucleotide adenylyltransferase (Nmnat) is a class of enzymes consisting of three members (Nmnat1-3). Nmnat1 is in nucleus and associated with Leber congenital amaurosis, a form of early-onset retinal degeneration, while Nmnat2 is in cytoplasm and a well-characterized neuroprotective factor. pac-man ghosts behavior
