Effect of sodium fluoride pretreatment on the efficacy of an in-office bleaching agent: An in vitro study.

This in vitro study evaluated the effect of sodium fluoride (NaF) on the bleaching efficacy using an artificial discolored bovine tooth model. Twenty specimens were prepared from bovine teeth by staining with black tea extract and were divided into two groups ( = 10). In control group, specimens were immersed in distilled water for 30 min.

Ezetimibe reduced hepatic steatosis induced by dietary oxysterols in nonhuman primates.

Oxidized cholesterol (oxysterols) plays an important and multifaceted role in lipid metabolism. Here we examined whether dietary oxysterols accelerate hepatic lipid accumulation and inflammation in nonhuman primates. We also examined the effect of the Niemann-Pick C1-like1 inhibitor, ezetimibe (Ez).
