WebTo examine the mechanism of /chloroacetonitrile (CAN)/ toxicity, /investigators/ studied its effect on glutathione homeostasis and its impact on oxidative DNA damage in gastric mucosal cells of rats.Following a single oral dose (38 or 76 mg/kg) of CAN, animals were sacrificed at various times (0-24 hr), and mucosa from pyloric stomach were collected. WebS4 containing 2,2,2-Triﬂuoroethanol, 1-propanol, Ethanol and Acetonitrile solvents, respectively are designed. The values of I, Jsc, FF, and η of the four designed DSSCs are calculated. First, the value of current is calculated using Eq. (16) and then the transition energy is obtained. The transition energy and radii are evaluated from Eqs.
