This paper reports absorption and fluorescence spectral studies of methyl 4-[(1E,3E)-4-phenylbuta-1,3-dienyl]benzoate (1), N,N-dimethyl-N-[4-[(1E,3E)-4-phenylbuta-1,3-dienyl]phenyl]amine (2), methyl 4-[(1E,3E)-4-[4-(dimethylamino)phenyl]buta-1,3-dienyl]benzoate (3) and 1-methyl-4-[(1E,3E)-4-[4-methoxyphenyl]buta-1,3-dienyl]benzoate (4) in homogeneous media of 1,4-dioxane and 1,4-dioxane-water b...
Topical application of caffeine sodium benzoate (caffeine-SB) immediately after UVB irradiation of SKH-1 mice enhanced UVB-induced apoptosis by a 2- to 3-fold greater extent than occurred after the topical application of an equimolar amount of caffeine. Although topical application of caffeine-SB or caffeine enhanced UVB-induced apoptosis, both substances were inactive on non-UVB-treated normal...
Probabilistic models were used as a systematic approach to describe the response of Escherichia coli O157:H7 populations to combinations of commonly used preservation methods in unpasteurized apple cider. Using a complete factorial experimental design, the effect of pH (3. 1 to 4.3), storage temperature and time (5 to 35 degrees C for 0 to 6 h or 12 h), preservatives (0, 0.05, or 0.1% potassium...
