Endogenous glucocorticoid secretion follows a conserved circadian pattern across species, with diurnal organisms (e.g., humans) showing peak concentrations during active phases (morning) and nocturnal species (e.g., rodents) displaying maximal levels during their active period (evening) (126).In humans, peak circadian cortisol secretion (approximately 06:0010:00h) (127) temporally coincides with maximal expression of tight junction proteins (occludin, claudin-5), and optimal BBB integrity

NAC works both orally and parenterally, which may be important since acetaminophen is available for oral, intravenous, or rectal administration (Table 3)

However, whether direct quenching reactions occur in vivo is unknown
