Anti-demineralizing protective effects on enamel identified in experimental and commercial restorative materials with functional fillers
In this way, glutathione protects pregnant women and babies from damaging environmental exposures such as pollution and cigarette smoke

The pharmacokinetic parameters assessed after single dose administration on Day 1 were: maximum concentration ( C max ), time to C max ( t max ), terminal elimination rate constant ( z , calculated using log-linear regression from at least three points), area under the concentrationtime curve (AUC) until time t (AUC 0t , calculated using the trapezoidal method), AUC extrapolated to infinity (AUC 0 , calculated as AUC 0t + C t / z , where C t is the last measurable drug concentration), proportion of residual AUC extrapolated to infinity (AUC extra , calculated as 100 [ C t / z ]/AUC 0 ), AUC from administration to 12 h on Day 1 (AUC 012 , calculated using the trapezoidal method), t (calculated as ln2/ z ), volume of distribution [ V z , calculated as dose/(AUC 0 z )] and total body clearance (CL t , calculated as dose/AUC 0 ) of NAC in plasma, and total amount excreted until time t (Ae 0t ), fraction excreted until time t (Fe 0t ) and renal clearance (CL r , Ae 0t /AUC 0 ) of NAC in urine
