(Sociedad Chilena de Quimica, 2012)4,4-Dimethyl-5,8-dihydroanthracene-1,9,10(4H)-trione (Q1) and 9,10-Dihydroxy-4,4-dimethyl-5,8-dihydro-1 (4H)-anthracenone (Q2), two molecules that inhibit cancer cell respiration, were selectively deuterated and dissolved ...
-
(2013)A molecularly imprinted polypyrrole polymer-based film and its properties regarding the recognition of gallic acid were investigated. The polypyrrole film was prepared by including a template molecule during the ...
-
(2009)Few works on neural networks-based robot controllers address the issue of how many units of neurons, hidden layers and inputs are necessary to approximate any functions up to a bounded approximation error. Thus, most ...
-
(2012)A high-performance liquid chromatography (HPLC) method for the determination of urocanic acid isomers extracted from human skin has been developed. Urocanic acid is a compound present in skin, accumulated in trans form ...
-
(2013)The aim of this study was to establish an analytical method to detect the presence of the responsible triterpenoids of the anti-inflammatory activity of the leaves of Ugni molinae (murtilla). Successive leaves extracts of ...
-
(2012)The formation of paramagnetic species from oncocalyxone A in aprotic medium was confirmed by performing in situ electrochemical-electron spin resonance (E-ESR) experiments. The high delocalization of the radical generated ...
-
(2013)Quinoa protein extracts (Q) were prepared and alkalised at pH 8 and 12 (Q-8 and Q-12). Qs were mixed with chitosan (CH) to form Q/CH mixtures. The optimal proportion of the mixtures was determined by the formation of ...
-
(2012)The electrochemical response of a glassy carbon electrode modified with carbon nanotubes (CNT) dispersed in two solvents, water and DMF, and two polymers, chitosan and Nafion is reported. The films were homogeneous when ...
-
(2012)The potential of microwave-assisted liquid-liquid and solid phase extraction coupled with fluorescence spectroscopy and employing one- to three-way spectral data was assessed in terms of their capacity for the rapid detection ...
-
(2012)In this study, two series of dihydropyridine-fused and pyridine-fused coumarins were synthesised and electrochemically characterised in aprotic medium. In both series, the most easily reducible groups were the endocyclic ...
-
(2012)The process of muscle remodeling lies at the core of most cardiovascular diseases. Cardiac adaptation to pressure or volume overload is associated with a complex molecular change in cardiomyocytes which leads to anatomic ...
-
(2013)A new nitrooxoisoaporphine derivative was synthetized and characterized by cyclic voltammetry and electron spin resonance. Its aqueous solubility was improved by complexes formation with β-cyclodextrin, heptakis(2,6-di-O- ...
-
(2012)It was examined the efficacy of Monascus purpureus standardized extract (Mp) on the endothelial dysfunction (ED) of rat aortic rings caused by oxidative stress as a consequence of their exposition to a high glucose ...
-
(Sociedad Chilena de Quimica, 2012)The efficiency of the adsorption process of the fungicides Captan and Thiram was studied in four Chilean soils from the VI [O'Higgins, (HGS)], VII [Talcarehue, (THL)], VIII [Diguillin, (DIG)] and Metropolitan [Maipo, (MAO)] ...
-
(Sociedad Chilena de Quimica, 2012)Biosolid model samples (BMSs) were developed to study the capacity of various matrixes to adsorb polybrominated diphenyl ethers (PBDEs) as a function of their composition. A commercial standard reference samples for biosolids ...
-
(2012)Inclusion of the organometallic MLn = [HOC 5H 4N• Cp 2TiCl][PF 6] (1), HOC 5H 4N• W(CO) 5 (2), HOC 5H 4N•Mo(CO) 5 (3), [HOC 6H 4CH 2CN•Cp 2TiCl] [PF 6] (4), HOC 6H 4CH 2CN•W(CO) 5 (5) and HOC 6H 4CH 2CN•Mo(CO) 5 (6) into ...
-
(Magnolia Press, 2015)Copyright © 2015 Magnolia Press. The hairy long-nosed armadillo, currently referred as Dasypus (Cryptophractus) pilosus, is an enigmatic species endemic to montane cloud forests and subparamo of Peruvian Andes. Its strikingly ...
-
(2012)The structure of the title compound, poly[(dihydrogenphosphato-?O)(mu 3-hydrogenphosphato)di-mu-oxido-(1,10-phenanthroline)copper(II)vanadium(V)], [CuV(HPO4)(H2PO4)O2(C12H8N2)]n, is defined by [(phen)Cu mu-(?2O:O'-VP2O10 ...
-
(2012)The leading cause of death in diabetic patients is cardiovascular disease; diabetic cardiomyopathy is typified by alterations in cardiac morphology and function, independent of hypertension or coronary disease. However, ...
-
(2012)Photoisomerization of a protein bound chromophore is the basis of the light sensing and signaling responses of many photoreceptors. Z-to-E photoisomerization of the Pr Cph1Δ2 phytochrome has been investigated by polarization ...
