-
(1989)2,2′-Azobis-[2-amidinopropane] initiated lipid peroxidation of egg yolk phosphatydil choline liposomes was measured by oxygen uptake and the emitted visible luminescence. Lipid peroxidation involved a chain process (kinetic ...
-
(JOHN WILEY, 2006-06)Herbal tea consumption is deeply and widely rooted amongst South-American populations. In view of the involvement of oxygen- and nitrogen-reactive species in the ethiogenesis of several diseases, the antioxidant properties ...
-
(1989)The exchange between bromide and chloride counterions at the surfaces of dioctadecyldimethylammonium vesicles has been examined through fluorescence quenching experiments. The quenching of the fluorescence of vesicle-incorporated ...
-
(2013)Chemical and structural alterations to lysozyme (LYSO), glucose 6-phosphate dehydrogenase (G6PD), and bovine eye lens proteins (BLP) promoted by peroxyl radicals generated by the thermal decomposition of 2,2′-azobis(2 ...
-
(Sociedad Chilena de Química, 1986)Pyrolysis of di-terbutylperoxyoxalate at 45ºC in the presence of acetaldehyde produces quantitative yields of tertbutanol and biacetyl. Luminescence arising from excited biacetyl is produced during the peroxide decomposition. ...
-
(1987)The deactivation of a number of excited polycyclic aromatic hydrocarbons by copper(II), cobalt(II), nickle(II) and chromium(III) in ethanol-water (1:1 by volume) has been investigated. In spite of the fact that most of the ...
-
(ELSEVIER, 2008-01-30)The distribution of urocanic acid (UCA) isomers between aqueous solutions and n-octanol, egg yolk phosphatidylcholine (eggPC) liposomes or bovine serum albumin (BSA) has been evaluated. Regarding its partitioning between ...
-
(1988)The polymerization of methyl methacrylate photosensitized by benzion methyl ether over a wide range of initiator absorbances was investigated. Both the polymerization rate and the polymer molecular weight distribution are ...
-
(2005)We have investigated the riboflavin (RF)-sensitized inactivation of glucose 6-phosphate dehydrogenase (G6PD) in the presence and absence of trans-urocanic acid (UCA). The inactivation of the enzyme results from its direct ...
-
(AMER SOC PHOTOBIOLOGY, 1996-06)An equation is proposed for the evaluation of partition or association constants from fluorescence properties (such as spectrum shape or anisotropy) whose values are not linearly related to the solute distribution. The ...
-
(1999)St I is a toxin present in the Caribbean Sea anemone Stichodactyla helianthus which is highly hemolytic in the nanomolar concentration range. Exposure of the toxin to free radicals produced in the pyrolysis of 2,2′ ...

-
(Informa Healthcare, 1989)The characteristics of the visible luminescence that follows the lipid peroxidative process were investigated either in the autoxidation of rat brain homogenates or in the azo-bis-arnidinopropane initiated lipid peroxidation ...
-
(1980)The photochemistry of alkanals in dilute solutions and in the presence of olefins and hydrogen donors was analysed and the results obtained are discussed taking as reference the photochemical behaviour of the alkanones. ...
-
(1986)The photochemistry of alkyl pyruvates of the type CH3COCOOCHR2 has been examined in solution using a combination of product studies and laser flash photolysis techniques. The results indicate that the main reaction path ...
-
(1990)The photochemistry of ethyl esters of α-oxo-carboxylic acids of the type RCOCO2CH2CH3 was examined using a combination of steady state irradiation and laser flash photolysis techniques. The experimental results indicate ...
-
(1989)Abstract The quenching of the benzophenone triplet by lysozyme and its constituent amino acids in aqueous solutions have been studied. Native lysozyme quenches the benzophenone triplet with a high rate constant, 4 × ...
-
(1985)Abstract— The quenching rate of triplet benzophenone in water and/or water mixtures has been determined employing vitamin C, vitamin E, cystine, cysteine, reduced and oxidized glutathione, methionine and DL‐penicillamine. ...
