A study was made on the spectroscopic properties of 4-hexylresorcinol (4HR) in several solvents at room temperature. Absorption and emission spectra were slightly affected by solvent polarity. Stokes' shifts were small (approximately 3000 cm(-1)) and the fluorescence quantum yields varied between 0.05 and 0.68, depending on the solvent. The spectral shifts(More)

We studied plasma lipoproteins in 2 groups of 50 women each, one with a high (A) and the other low socio-economic status (B). Age, caloric intake, energy output and weight for height relation were comparable in both groups. A significant difference was found in plasma levels of triglycerides (A = 138.9 vs B = 104.8 mg/dl), total cholesterol (A = 226.9, B =(More)
