(Sociedad Chilena de Quimica, 2015)In this work, we report a fast and accessible method for quantification of cetyltrimethylammonium bromide (CTAB) in solutions of gold nanorods (GNRs) by bromophenol blue (BPB) ion-paring formation and spectrophotometric ...
-
(Elsevier B.V., 2015)A rapid, sensitive and efficient analytical method based on the use of ionic liquids for determination of non-steroidal anti-inflammatory drugs (NSAIDs) in water samples was developed. High-performance liquid chromatography ...
-
(Elsevier B.V., 2017)© 2016 Elsevier B.V. Montmorillonite (MMT) clays were modified by the intercalation into their galleries of ionic liquids (IL) based on imidazolium quaternary ammonium salts. This new eco-materials exhibited good features ...

(BioMed Central Ltd., 2004-06-04)Arabidopsis thaliana copper metallochaperone CCH is a functional homologue of yeast antioxidant ATXI, involved in cytosolic copper transport. In higher plants, CCH has to be transported to specialised cells through ...
-
(Universidad de Chile, 2012)El medicamento es un elemento de alta complejidad, no sólo desde el punto de vista de la tecnología asociada y la repercusión que tienen estos en el tratamiento de las enfermedades, sino también es un bien transable en el ...
-
(Pergamon Press Ltd, 1993)Phytochemical study of Escallonia myrtoidea, E. illinita, E. alpina and E. pulverulenta led to the isolation of asperuloside and other C10-iridoid glycosides. From E. myrtoidea a new iridoid glycoside was isolated and ...

(ELSEVIER SCIENCE INC, 2010-02-15)We investigate here the role of reactive oxygen species and nitric oxide in iron-induced cardiomyocyte hypertrophy or cell death Cultured rat cardiomyocytes incubated with 20 mu M iron (added as FeCl3-Na nitrilotriacetate, ...
-
(Harwood Academic Publishers GmbH, 2001)Intestinal epithelial cells have an active apical iron uptake system that is involved in the regulated absorption of iron. By the action of this system, intestinal cells acquire increasing amounts of iron with time. Since ...
-
(2002)The compound ([CpFe(dppe)]2[μ-SCH2CH2S-S,S′]) (PF6)2 ([1][PF6]2) has been synthesized and its magnetic properties have been investigated by susceptometer quantum interface device (SQUID) measurements in the temperature ...
-
(Endocrine Society, 2020)Mitochondrial damage is implicated as a major contributing factor for a number of noncommunicable chronic diseases such as cardiovascular diseases, cancer, obesity, and insulin resistance/type 2 diabetes. Here, we discuss ...
-
(Sociedad Chilena de Química, 2014)Differences in association constants values of cyclodextrin inclusion complexes can be found in the literature. Most of the times, different experimental conditions have been used leading to different results. This paper ...
-
(AMER SOC MICROBIOLOGY, 2001-05)We expressed cDNAs coding for manganese peroxidases (MnPs! from the basidiomycetes Ceriporiopsis subvermispora (MnP1) and Phanerochaete chrysosporium (H4) under control of the alpha -amylase promoter from. Aspergillus ...
-
(Universidad de Chile, 2009)Introducción: El Cáncer de Ovario Epitelial (COE) es el cáncer ginecológico con mayor mortalidad en mujeres post-menopáusica. Su carcinogénesis y progresión neoplásica es atribuida a múltiples moléculas relacionadas con ...
-
(Universidad de Chile, 2011)El receptor de alta afinidad de la neurotrofina NGF, TRKA, ha sido asociado con distintos tipos de cáncer, pudiendo encontrarse isoformas de este receptor. En el cáncer ovárico no se han descrito isoformas de este receptor, ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2006-06)Mixed complexes of animosugars and 1,10-phenanthroline (phen) with cobalt(III), with the composition Co(III)(phen)(2)sugar, disproportionate in aqueous solution in approximately one month, giving non ionic tris-aminosugar ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2004-06)Mixed bis-phenanthroline Co(III) complexes with amino sugars disproportionate over a period of months, giving non-ionic tris(aminosugar)complexes. The complex with alpha-D-glucosamine has the Lambda-configuration with ...
-
(2001)Genetic analyses of the lignin-degrading fungus Ceriporiopsis subvermispora is complicated by a dikaryotic nuclear condition and the absence of spore forms. Previous investigations had identified a family of closely related ...
-
(Frontiers media SA, 2017)Antarctica is an attractive target for human exploration and scientific investigation, however the negative effects of human activity on this continent are long lasting and can have serious consequences on the native ...
