Alcohol leads to the induction of P450 enzymes that convert acetaminophen to N-acetyl-p-benzoquinoneimine (NAPQI), a toxic metabolite that causes hepatotoxicity in the setting of acetaminophen overdose.
M. Acidosis or decreased NAD+ and increased NADH do not play a direct role in acetaminophen-mediated hepatotoxicity!
During pregnancy, progesterone is produced by the:
corpus Luteum for the first 7-10 weeks of gestation, secondary to stimulation by human chorionic gonadotropin from the placental syncytiotrophoblast.
after 7+ weeks, it is primarily produced by the placenta.
