In this study, 80 lipsticks were obtained and evaluated using Raman spectroscopy at excitation wavelengths of 532 and 780 nm. Fluorescence severely limited analysis with the 532 nm line while the 780 nm line proved useful for all samples analyzed. It was possible to differentiate 95% of the lipsticks evaluated based on one or more Raman peaks. However,(More)
The effect of naltrexone vs. placebo on alcohol-provoked flushing was studied in 20 healthy subjects of Oriental ancestry and 20 healthy white subjects. The intensity of the flushing reactions was assessed by two independent methods, the cutaneous perfusion index by laser Doppler velocimetry and the change in malar thermal circulation index by(More)
