Does zinc supplementation reverse alcohol-induced steatosis in mice through reactivating hepatocyte nuclear factor-4alpha and peroxisome proliferator-activated receptor-alpha?
Zinc supplementation reverses alcoholic steatosis, and reactivation of HNF-4alpha and PPAR-alpha by increasing zinc availability and inhibiting oxidative stress are potential mechanisms underlying these beneficial effects of zinc on hepatic lipid homeostasis.
Our results indicate that non-classic cytomorphological signs can improve the sensitivity of cytology for detecting HPV. Minimally abnormal Pap smears lacking mild nuclear changes (16%) in the present study--do not require further molecular HPV testing.
