(1992)Diphenylmethyl radicals generated photochemically from 1,1,3,3-tetraphenylacetone (TPA) or 1,ldiphenylacetone (DPA) have been examined in vesicles using laser flash photolysis techniques. Experiments in small vesicles ...
-
(Indian Academy of Sciences, 2017)Phenolic compounds can be considered as the most important bioactive compounds in Mediterranean diet. However, many of the complex connections between phenols antioxidant reactivity and their molecular structure remain ...
-
(Elsevier, 2018-06)We studied the photothermal release of carboxyfluorescein (CF) linked to the gold surface of gold nanorods (GNRs) by two Diels-Alder adducts of different lengths (n = 4 and n = 9). The functionalized GNRs were irradiated ...
-
(University of Chicago Press, 2019)While there is strong evidence that more productive plants select into exporting, the literature has struggled to identify export-related efficiency gains within plants. We show that this is due to the common use of ...
-
(Royal Soc., 2015)It has been proposed that sub-inhibitory concentrations of antibiotics play a role in virulence modulation. In this study, we evaluated the ability of Salmonella enterica serovar Typhimurium (hereafter S. Typhimurium) to ...
-
(Elsevier, 2018)Cardiac fibroblasts (CF) are key cells for maintaining extracellular matrix (ECM) protein homeostasis in the heart, and for cardiac repair through CF-to-cardiac myofibroblast (CMF) differentiation. Additionally, CF play ...
-
(Elsevier, 2016)Cardiac inflammation can be produced by pathogen-associated molecular patterns (PAMPs), from parasitic, bacterial or viral origin; or by danger-associated molecular patterns (DAMPs), released from dead cells after cardiac ...
-
(Elsevier, 2011)Melanocortin receptors (MCRs) are involved in physiological responses to ACTH, as well as to -, - and -melanocytestimulating hormone ( -, - and -MSH). Their expression has previously been analyzed in various bovine ...
-
(Sociedad Chilena de Quimica, 2001)This communication describes the application of a hollow-fiber-type solid supported liquid membrane technique to the study of recovery and enrichment of molybdenum with Alamine 336 (a long chain tertiary amine) from acid ...
-
(TAYLOR & FRANCIS AS, 2004-04)The cerebrospinal fluid (CSF) is in direct contact with the extracellular space of the CNS, thus biochemical processes in the CNS could potentially be reflected in the CSF. Changes in extracellular matrix (ECM) proteins ...
-
(ACADEMIC PRESS INC, 2000-07-05)This study aims to elucidate the signaling pathway for insulin-like growth factor-1 (IGF-1) in cultured neonatal rat cardiomyocytes and particularly the role of IGF-1 in cardiac apoptosis, IGF-1 stimulated polyphosphoinositide ...
-
(MARCEL DEKKER INC, 2004-06)Copper (Cu) mining activities are very important in central Chile. The present study consists in determining the distribution and availability of copper, arsenic (As), and lead (Pb) in soils near a smelting facility, in ...
-
(2013)O objetivo deste estudo foi utilizar a técnica de difusão em filmes finos por gradiente de concentração (DGT) para a avaliação da disponibilidade de cobre em solos com elevados níveis do metal, que foi alterado com ...
-
(ROYAL SOC CHEMISTRY, 2004)Following our research on copper, arsenic and antimony in Chilean ecosystems, a study to understand the mobility and transport of these elements from soil to plants was carried out. So, the aim of this study, which follows ...
-
(Springer, 2015)Phenolic compound content in Sorbus americana Marsh and Lonicera oblongifolia (Goldie) Hook berries was determined for the first time. An improved solid-liquid microextraction (SLME) method combining with highperforma ...
-
(Blackwell Publishing Ltd, 2017)© 2017 Institute of Food Science and Technology Pomegranate peels and seeds are industrial residues considered interesting sources of punicalagin (PU) and punicic acid (PA), respectively. To optimise their extraction process ...
-
(Soil Science Society of America, 1984)Extraction of Cd,Cu, Ni and Zn by BaCl(Ba(ClO-4)2 solutions from El Recuerdo(Vertisol) and Puerto Octay (Andept)soils was used to measure the amounts of metals remaining extractable during a 60-d storage period under air-dry ...
-
(2004)To evaluate the potential use of mesquite (Prosopis chilensis (Mol) Stuntz) seed gum, the behaviour of the gum was studied using two extraction methods (alkaline and acid), different pH values, two concentrations (0.2 and ...
-
(SOC BRASILEIRA QUIMICA, 2006-12)It is studied the extraction of cadmium( II) ions from acidic aqueous solutions using a stirred transfer cell-type emulsion liquid membrane ( ELM) prepared by dissolving in kerosene, with D2EHPA ( an alkylphosphoric acid) ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2001-06)This communication describes the application of a hollow-fiber-type solid supported liquid membrane technique to the study of recovery and enrichment of molybdenum with Alamine 336 (a long chain tertiary amine) from acid ...
