(1993)When the rat kidney is subjected to ischemia and reperfusion, changes in glutathione content and in lipid peroxidation are produced in the cortex and in the medulla. The cortex shows a decrease in the glutathione content ...
-
(Elsevier, 2011)The role of lipopolysaccharide (LPS) in entry of Salmonella Typhimurium into epithelial cells remains unclear. In this study, we tested the ability of a series of mutants with deletions in genes for the synthesis and ...
-
(Birkhäuser-Verlag, 1986)We have observed a differential effect of silybin dihemisuccinate on rat liver microsonal oxygen consumption and on lipid peroxidation induced by NADPH-Fe2+-ADP and t-butyl hydroperoxide. These results are ascribed to the ...
-
(Frontiers Media, 2021)Fatty acid overload, either of the saturated palmitic acid (PA) or the unsaturated oleic acid (OA), causes triglyceride accumulation into specialized organelles termed lipid droplets (LD). However, only PA overload leads ...

(AMER CHEMICAL SOC, 2001-10-30)Deuterium quadrupole splittings from two series of optical isomers, L- and D-N-acyl-l-phenyl-d(5)-2-aminopropane, with linear acyl chains ranging from I to 10 carbon atoms, were measured using H-2 NMR spectroscopy. Both ...
-
(Institute of Food Technologists, 2002)Cholesterol oxidation, products (COPs) are present in biological tissues and in foods. The inhibitory effect of antioxidants, such as tocopherols, on COPs formation has been only partially investigated. The antioxidant ...
-
(NATURE PUBLISHING GROUP, 2009-05)The Angiotensin II (Ang II) type 1 (AT(1)R) and type 2 (AT(2)R) receptors are increased in the heart following myocardial infarction and dilated cardiomyopathy, yet their contribution at a cellular level to compensation ...
-
(1986)Human fetal hemoglobin assayed in a peroxidizing system shows an increased prooxidative effect when compared to human adult hemoglobin. This effect is related only to the oxyhemoglobin form since both fetal and adult ...
-
(2003)The formation of inclusion complexes of well-known 1,4-dihydropyridine calcium antagonists, such as nifedipine (NF) and nicardipine (NC), with beta-cyclodextrin (betaCD) was investigated by differential pulse polarography ...
-
(AOAC INTERNATIONAL, 2002-11)Lercanidipine in ethanol-0.04M Britton-Robinson buffer (20 + 80) gives an irreversible anodic response on a glassy carbon electrode in a broad pH range (2-12) that depends on pH. This signal can be attributed to oxidation ...
-
(BioMed Central, 2017)Background: Salmonella pathogenicity island (SPI)-13 is conserved in many serovars of S. enterica, including S. Enteritidis, S. Typhimurium and S. Gallinarum. However, it is absent in typhoid serovars such as S. Typhi and ...
-
(Sociedad Chilena de Quimica, 2000)Physicochemical parameters, ε, λ, solubility in water and Brij-35, pKa, Ka and photostability for dihydroeuparin, 5-acetyl-2, 3-dihydro-6-hydroxi-2-isopropenyl-benzo (b) furan (from Senecio Graveolens), were obtained and ...
-
(2012)In this study, two series of dihydropyridine-fused and pyridine-fused coumarins were synthesised and electrochemically characterised in aprotic medium. In both series, the most easily reducible groups were the endocyclic ...
-
(Universidad de ChilePrograma Cybertesis, 2006)El oxígeno molecular singulete es la especie excitada de menor energía del oxígeno y se encuentra presente en los sistemas biológicos junto a otras especies reactivas del oxígeno. La alteración del balance normal de las ...
-
(Universidad de Chile, 2019)Los glucocorticoides son hormonas esteroidales secretadas por las glándulas suprarrenales en un proceso dependiente de la actividad circadiana del eje hipotálamo-hipófisis-adrenal (HHA) o de un estímulo exógeno. Se sabe ...
-
(Universidad de Chile, 2015)La shigelosis es una infección intestinal aguda causada por bacterias del género Shigella, cuyos síntomas varían desde diarrea acuosa hasta disentería bacilar inflamatoria grave. Shigella es un patógeno cuyo único hospedero ...
-
(Universidad de la Frontera. Facultad de Ciencias Agropecuarias, 1999)La dinámica del carbono se evaluó en suelos con problemas de acidificación y de alto contenido de Al activo. En estos estudios, además se incluyen los resultados obtenidos en sistemas de cero-labranza, para definir en ...
-
(Universidad de Chile, 2019)La luz es uno de los recursos energéticos más abundantes en la Tierra, por lo que los organismos han desarrollado diversas estrategias para transformar la luz en energía química. A la fecha, se han descrito dos mecanismos ...
-
(Birkhauser Boston, 2017)The mechanisms of action and structural determinants of lipoxygenases inhibitors have been explored on several occasions, but many questions remain unanswered, especially about the differences of the inhibition mechanisms ...
