Curcumin is a molecule found in turmeric root that has anti-inflammatory, antioxidant, and anti-tumor properties and has been widely used as both an herbal drug and a food additive to treat or prevent neurodegenerative diseases. To explore whether curcumin is able to ameliorate HIV-1-associated neurotoxicity, we treated a murine microglial cell line (N9)(More)
A sensitive, accurate and reproducible analytical method was developed and validated to quantify perfluorooctanoic acid (PFOA) and its salts in the coating layer of nonstick pan. Scraped samples of 0. 5 gram were directly extracted with acetonitrile using an accelerated solvent extractor at 175 degrees C, 10. 3 MPa for 20 min. After rotary evaporation(More)
For human skin, high water content and low sebum secretion are considered to be main features of fair skin. To explore the proper personal care regimen for facial skin, we investigated the change of skin physiologic parameters after cosmetic application by measuring the skin water content, transepidermal water loss, and skin sebum secretion on facial skin(More)
A comprehensive analytical method based on isotope dilution-liquid chromatography-tandem mass spectrometry has been developed for the determination of N-nitrosodiethanolamine in cosmetics. Water-soluble cosmetic samples were extracted with water. The extract was centrifuged, then the upper solution was cleaned up by an Oasis HLB solid phase extraction(More)
Our previous studies have shown that infection with the gp120 V3 loop can cause human immunodeficiency virus-1 associated neurocognitive disorders. Curcumin has been shown to improve these effects to some degree, but the precise mechanisms remain unknown. The present study analyzed the neuroprotective effect and mechanism of curcumin in relation to(More)
