-
(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 ...
-
(Pergamon Press, 1990-11-30)Boldine, in low micromolar concentrations, was able to prevent brain bomogenate autooxidatíon, the 2,2'·uobis(2·amidinopropane)(AAP)·induced Iipid peroxidation of red cell plasma rnembranes, and the AAP·induced inactivation ...
-
(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 ...
-
(AMER PHYSIOLOGICAL SOC, 2002-03)We studied the effect of H2O2 on the gating behavior of large-conductance Ca2+-sensitive voltage-dependent K+ (K-V,K-Ca) channels. We recorded potassium currents from single skeletal muscle channels incorporated into ...
-
(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. ...
-
(Springer Science+Business, 2016)Preservation, storage, and safe transport of samples are key factors affecting brown algal phlorotannin (phenolics) quantification, their extraction yield, and antioxidant activity. This is especially relevant when field ...
-
(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 ...
-
(MDPI, 2015)On 4 and 8 January 2014, at the height of the austral summer, intense wildfires in forests and dry pastures occurred in the Melipilla sector, located about 70 km to the southwest of Santiago, the Chilean capital, affecting ...
-
(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 ...
-
(1986)Oxygen uptake by erythrocytes exposed to t‐butyl hydroperoxide (t‐BHP) exhibited an induction period. The rate of oxygen consumption can be reduced by antioxidants and blood plasma. The induction time was not appreciably ...
-
(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 ...
-
(1986)The interactions of neutral molecules with ionic micelles are analyzed. The cell and mass action models are presented in order to provide a semiquantitative description of the solubilization process. Both approaches are ...
-
(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'- ...
