(ELSEVIER SCIENCE BV, 1997-03-18)The cDNA, for xylanase B from Penicillium purpurogenum was cloned and sequenced. This DNA encodes a protein of 208 amino acids which is expected to yield a protein of 183 residues upon processing of the N terminus. The ...
-
(Royal Soc Chemistry, 2018-04-28)Gold nanoparticles with specific optical properties in combination with the CLPFFD peptide that exhibits selectivity for beta-amyloid (A beta) aggregates are promising photothermal absorbers for application in Alzheimer's ...
-
(Frontiers Media, 2021)We computationally explore an alternative to stabilize one-dimensional (1D) silicon-lithium nanowires (NWs). The Li12Si9 Zintl phase exhibits the NW 1 ∞[Li6Si5], combined with Y-shaped Si4 structures. Interestingly, ...
-
(Frontiers Media, 2022)Copper mining tailings are characterized by high concentrations of heavy metals and an acidic pH, conditions that require an extreme adaptation for any organism. Currently, several bacterial species have been isolated and ...
-
(Sociedad Chilena de Química, 2017)Hydrogen peroxide (H2O2) plays an important role as an intermediary in different biological, chemical and environmental systems. It has been widely used as an oxidizing and antimicrobial agent, in germicides production and ...
-
(Wiley-V C H Verlag GMBH, 2018)For the first time Co2SnO4 (CTO)/Carbon nanotubes (CNT) composites were prepared and used to modify glassy carbon electrodes for the amperometric determination of hydrogen peroxide. The catalytic activity of composites ...
-
(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 ...
