-
(Frontiers Media, 2018)The alpha 7 nicotinic acetylcholine receptor (nAChR) is expressed in neuronal and non-neuronal cells and is involved in several physiopathological processes, and is thus an important drug target. We have designed and ...
-
(Sociedad Chilena de Química, 2002)Se desarrolló una metodología confiable para la identificación y cuantificación de Hidrocarburos Aromáticos Policíclicos (Polycyclic Aromatic Hydrocarbons, PAHs) en aerosoles atmosféricos, que incluye la extracción con ...
-
(2010)Metsulfuron-methyl sorption/desorption behavior was studied through batch sorption experiments in three typical volcanic ash-derived soils belonging to Andisol and Ultisol orders. Their distinctive physical and chemical ...
-
(Laser Pages Publ., 1979)Cationic micelles of hexadecyltrimethyl ammonium bromide (CTABr) increase the rate of dephosphorylation of p‐nitrophenyldiphenyl phosphate (PNPDPP) by aryloxide ions by factors of almost 104. The rate‐surfactant profiles ...
-
(1975)The spontaneous hydrolysis of 2,4-dinitrophenyl phosphate dianion (I) is catalyzed by cationic micelles of the choline-derived surfactant (II, n-C16H33N+Me2CH2CH2OHBr-), but this surfactant is no more effective than ...
-
(Wiley-V CH Verlag GMBH, 2007-07)Tne reductive electrochemistry of 1-methyl-4-nitro-2-hydroxymethylimidazole, a 4-nitroimidazole derivative, was examined in the presence of surfactants anionic as sodium dodecyl sulfate (SDS), nonionic, Triton-X, Cationic, ...
-
(1969)The reactions between hydroxide or fluoride ion and p-nitrophenyl diphenyl phosphate, catalyzed by micelles of cetyltrimethylammonium bromide, are inhibited by phenyl, diphenyl, and p-t-butylphenyl phosphate. With decreasing ...
-
(1970)Micellar effects upon the reaction between hydroxide ion and bis-2,4-dinitrophenyl phosphate to give 2,4-dinitrophenyl phosphate have been examined. The reaction is catalyzed up to 30-fold by cationic micelles of ...
-
(Nature, 1963)RECENT work appears to show that phospholipids play a fundamental part in membrane physiology1,2. The participation of protein has been thought by some to be more doubtful since external application of proteases seems not ...
-
(2008)The aim of this work was to develop a procedure for encapsulation of diltiazem HCl by spray coagulation. Factors affecting the formulations such as the effect of NaCl on the solubility of diltiazem in alginate solution, ...
-
(2009)Bioactive compounds of pulp (CP) and ethanolic (CE) extracts of the cactus pear (Opuntia ficus-indica) were encapsulated with maltodextrin (MD) or inulin (I). A 22 statistical factorial design was then used to study the ...
-
(Elsevier Ltd, 2016)© 2015, Elsevier Ltd. All rights reserved. Haematococcus pluvialis is a natural source of astaxanthin (AX). However, AX loses its natural protection when extracted from this microalga. In this study, a supercritical fluid ...
-
(Elsevier, 2014)Pulp (CP) and ultrafiltered (UF) cactus pear extracts were encapsulated with Capsul (C) by applying a central composite design (CP–C and UF–C systems) by spray-drying. To evaluate the effect of the extract, microparticles ...
-
(Elsevier, 2014)In this study, six non-steroidal anti-inflammatory drugs (NSAIDs) were extracted from water samples using the rotating-disk sorptive extraction (RDSE) technique. The extraction disk device contains a central cavity that ...
-
(Santiago, Chile, Círculo de Estudios de Química y Farmacia, 1931)En los análisis bromatológicos de diferentes productos alimenticios, como chocolates y bizcochos de leche, mazapanes, pasteles y galletas a base de mantequilla, etc. se tropieza a menudo con la dificultad de reconocer, si ...
-
(Frontiers Media, 2018)Studies conducted in rodents subjected to chronic stress and some observations in humans after psychosocial stress, have allowed to establish a link between stress and the susceptibility to many complex diseases, including ...
-
(PERGAMON-ELSEVIER SCIENCE LTD., 2011-10)Adverse reactions of acetaminophen have been associated to oxidative stress, which may be elicited by reactive oxygen species (ROS) and/or production of the metabolite NAPQI. Both phenomena would arise through the activity ...
-
Microsomal oxidative stress induced by NADPH is inhibited by nitrofurantoin redox biotranformation (Informa Healthcare, 2014)Nitrofurantoin is used in the antibacterial therapy of the urinary tract. This therapy is associated with various adverse eff ects whose mechanisms remain unclear. Diverse studies show that the nitro reductive metabolism ...
-
(BLACKWELL PUBLISHING, 2005-06)Activation of microsomal UDP-glucuronyltransferase (UDPGT) activity by treatment of hepatic microsomes with either detergents or Fe3+/ascorbate pro-oxidant system has been reported; however, definite mechanisms underlying ...
