(PERGAMON-ELSEVIER SCIENCE LTD, 1996-05)Ecto-nucleotidases may have a role in the regulation of purinoceptor-mediated responses. ATP-diphosphohydrolase or apyrase has been described as an ecto-nucleotidase, which is characterized by a low specificity for its ...
-
(ACADEMIC PRESS AUST, 1996-08)Extracellular nucleotides interact with specific receptors on the cell surface and are locally metabolized by ecto-nucleotidases. Biochemical characterization of the ATPase and ADPase activities detected in rat heart ...
-
(2002)ATPase and ADPase activities capable of hydrolyzing nucleoside di- and triphosphates in the presence of Ca2+ are present in synovial membrane of metacarpophalangeal joint mainly associated to membrane fractions. These ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1991)1. Calcium-stimulated ATPase-ADPase activities were studied in a microsomal fraction of rat placental tissue. 2. The kinetic characteristics correspond to those of ATP-diphosphohydrolase, also known as apyrase (E.C. ...
-
(Sociedad Chilena de Cardiología y Cirugía Cardiovascular, 2006)Históricamente, la apoptosis y la necrosis han sido consideradas como las dos formas fundamentales de muerte celular. Sin embargo, evidencias recientes sugieren que la muerte celular programada no está confinada sólo a ...
-
(ELSEVIER SCI LTD, 2007)Two deteriorative pathways (autolysis and microbiological activity) were studied in farmed Coho salmon (Oncorhynchus kisutch) for 24 days during chilled storage. These changes were assessed by nucleotide degradation ...
-
(Royal Soc, England, 2021)The regulation of gene expression is a key factor in the development and maintenance of life in all organisms. Even so, little is known at whole genome scale for most genes and contexts.We propose a method, Tool forWeighted ...
-
(Nature, 2020)Autophagy is an evolutionarily conserved process that plays a key role in the maintenance of overall cellular health. While it has been suggested that autophagy may elicit cardioprotective and pro-survival modulating ...
-
(American Society for Clinical Investigation, 2015)Cardiovascular disease is the leading cause of death worldwide. As such, there is great interest in identifying novel mechanisms that govern the cardiovascular response to disease-related stress. First described in failing ...
-
(Public library science, 2018)Vascular smooth muscle cells (VSMC) dedifferentiation from a contractile to a synthetic phenotype contributes to atherosclerosis. Atherosclerotic tissue has a chronic inflammatory component with high levels of tumor necrosis ...
-
(Colegio Químico Farmacéutico de Chile, A. G., 1989)La importancia del tema se debe a la especial relación entre alimentos y enzimas. Las enzimas, catalizadores bioquímicos, cumplen diversas funciones en los alimentos, provocando en algunos casos, graves daños en el color, ...
-
(AMER CHEMICAL SOC, 2000-04-18)Deuterium quadrupole splittings of benzyl alcohol-d(5) and a series of alkyl benzyl-d(5), ethers, with linear aliphatic chains from 1 to 12 carbon atoms, were measured using H-2 NMR spectroscopy. These molecules were ...
-
(AMER CHEMICAL SOC, 1997-12-24)Deuterium quadrupole splittings from the aromatic ring of a series of linear benzyl-d(5) alkyl ethers, with alkyl chain length from 1 to 15 carbon atoms, have been measured using H-2-NMR spectroscopy. These molecules, 20% ...
-
(American Chemical Society, 2011)The first aim of the present work (study 1) was to analyze ethyl acetate, 70% acetone, and 70% methanol extracts of the peel, pulp, and seed from two avocado (Persea americana Mill.) varieties, namely, ‘Hass’ and ‘Fuerte’, ...
-
(International Association Food Protection, 2018)The genus Salmonella has more than 2,600 serovars, and this trait is important when considering interventions for Salmonella control. Bacteriophages that are used for biocontrol must have an exclusively lytic cycle and the ...
-
(Taylor & Francis, 2020)Microbialites are organo-sedimentary structures formed as minerals precipitate due to the metabolic activity of microorganisms. They can be differentiated by their internal mesostructure into stromatolites and thrombolites. ...
-
(1997)Polychlorinated biphenyls (PCBs) are one of the most widely distributed chlorinated pollutants in the environment. Bioremedation seems to be a promising approach for the clean-up of PCB-contaminated soils and aquatic ...
-
(Taylor and Francis, 2016)Autophagy is mainly regulated by post-translational and lipid modifications of ATG proteins. In some scenarios, the induction of autophagy is accompanied by increased levels of certain ATG mRNAs such as MAP1LC3B/LC3B, ATG5 ...
-
(México Federación Latinoamericana de Química, 1990)The leaves of P. glandulosa contain the active meroterpenoid bakuchiol, as well as angelicin, psoralen and a new cinnamic derivative.
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-09)Sulphur distribution with an insight in S-organic fractions was studied in volcanic-ash derived soils of Chile (Typic Dystrandepts, Palehumult) by isolating each fraction and measuring S directly by instrumental elemental ...
