(Sociedad Chilena de Tecnología de Alimentos, 2002)El queso es un importante producto derivado de la leche; la décima parte de la producción anual en el mundo se destina a la elaboración de queso. Para su fabricación se debe coagular la leche, lo que tiene por objetivo ...
-
(SPRINGER VERLAG, 1993-11)Methyl methacrylate and methyl acrylate were grafted onto chitosan by using potassium persulfate alone as redox initiator and in combination with MnCl2 and CuCl2, as inorganic, and both ammonium tartrate and oxalate as ...
-
(BLACKWELL PUBLISHING, 2006-05)Recent studies suggest thyrotrophin-releasing hormone (TRH) serves as a neurotransmitter and thereby provides a functional vegetative connection between the brain and the ovary. In the present study, magnocellular neurones ...
-
(Public Library of Science, 2019)Background: Enterotoxigenic Escherichia coli (ETEC) encoding heat-stable enterotoxin (ST) alone or with heat-labile enterotoxin (LT) cause moderate-to-severe diarrhea (MSD) in developing country children. The Global Enteric ...
-
(1994)A nonradioactive method is developed to detect DNA polymerase activity after sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis containing gapped DNA as template. The technique is based on the use of digoxigenin- ...
-
(Nature Publishing Group, 1968)Observations of the colour of Serratia marcescens colonies and of chromatographic behaviour of Serratia pigments recently led Allen to suggest that "pH is not the only factor involved in the colour change of prodigiosin ...
-
(Sociedad Chilena de Química, 1998)From Trevoa trinervis Miers (Rhammnaceae), a plant used in Chilean folklore medicine, a triterpenoid called colubrinic acid, has been isolated from a pharmacological active extract. Its structure has been established by ...

(NATL INST ALCOHOL ABUSE ALCOHOLISM, 2006)Two lines of rats bred to differ in their voluntary alcohol consumption-the alcohol-abstaining UChA rats and the alcohol-drinking UChB rats-differ in how effectively toxic acetaldehyde is removed during alcohol metabolism. ...
-
(MDPI, 2020)This study focused on applying different high hydrostatic pressure + carbon dioxide (HHP + CO2) processing conditions on refrigerated (4 degrees C, 25 days) farmed coho salmon (Oncorhynchus kisutch) to inactivate endogenous ...
-
(ELSEVIER, 2007)Alkyl esters of gallic acid inhibited the respiration rate of mouse sarcoma 786A and mouse mammary adenocarcinoma TA3 cell lines and its multiresistant variant TA3-MTX-R more effectively than gallic acid, both in the ...
-
(ELSEVIER SCIENCE BV, 2009-05-18)The reduction properties of four acceptor polipyridyl ligands modified with quinones were studied by different experimental methods, as cyclic voltammetry and ESR spectroscopy, and by theoretical calculations. ESR spectra ...
-
(2012)Efficient lignin depolymerization is unique to the wood decay basidiomycetes, collectively referred to as white rot fungi. Phanerochaete chrysosporium simultaneously degrades lignin and cellulose, whereas the closely related ...
-
(1967)Dimensional analysis and the theory of biological similarities were applied to the mammalian respiratory system. Through dimensional and solution matrices a set of 9 Pi-numbers of Buckingham was obtained. Products of ...

Comparative SCF MO studies for some histamine analogues as agonists of the H2 receptor of histamine (Sociedad Chilena de Química, 1999)This paper presents SCF AM1 and CNDO/2 RF calculations of the potential energy surface of histamine monocation (HA) and the agonists 2-(4-thiazolyl)ethylamine (TIA) and 2-(4-oxazolyl)ethylamine (OXA). the similarity of ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-08)Cyclic voltammetry and electron spin resonance techniques were used in the investigation of novel 3-alkoxy- and 3-hydroxy-1-[omega-(dialkylamino)alkyl]-5-nitroindazole derivatives. A self-protonation process involving the ...
-
(ELSEVIER SCIENCE BV, 2004-01)The aim of this work was to evaluate the possibility of using mixtures and/or polyelectrolyte complexes from both chitosan-alginate and chitosan-carrageenan as prolonged drug release systems. Different dissolution profiles ...
