Preferential solvation of a dicyanate ester monomer and poly(sulfone) in different organic solvents by size-exclusion chromatography.
2002
Preferential solvation parameters A in the ternary systems solvent (1) -monomer (2) -polymer (3) were determined as a tool to measure the compatibility between the cyanate ester monomer Arocy B10 and poly(sulfone), PSF, in the presence of three organic solvents: tetrahydrofuran, dimethylformamide and dicloromethane. The A parameter was measured by size-exclusion chromatography at different monomer-to-polymer ratios. The quantitative evaluation was rigorously made at polymer-diluted conditions. PSF was found to be preferentially solvated by the monomer. Concerning the solvent used, systems containing tetrahydrofuran showed the strongest solvation, the lowest A values being those obtained in …
Association of Taste Perception for Sweet, Salt, Sour, Bitter and Umami and Food Intake Among Community-dwelling Adults in the PREDIMED-PLUS Trial (P…
2019
OBJECTIVES: To investigate the association between taste perception for sweet, salt, sour, bitter and umami and food category intakes. We hypothesized that greater taste perception will be inversely associated with the amount consumed. METHODS: A cross-sectional baseline analysis was performed on community-dwelling overweight adults with metabolic syndrome (N = 367, 55–75y) from the PREDIMED-PLUS Trial, University of Valencia Center, Spain. Taste perception was determined by challenging subjects with standard solutions of sweet, salt, sour, bitter and umami (400 mM sucrose, 200 mM NaCl, 34 mM citric acid, 5.6 mM phenylthiocarbamide (PTC), 200 mM monopotassium glutamate, respectively) and ev…
Sur "Israél-Palestine, Le Cancer", un devoir civique d'intelligence de la complexité
2004
Se trata de un dossier coordinado por J. L. Le Moigne sobre la polémica y acciones en torno al texto "Isráel-Palestine, le Cancer", escrito por Morin, Nair y Sallenave en 2002. José Vidal-Beneyto fue uno de los firmantes del llamamiento en apoyo a Edgar Morin del 30 de marzo de 2004.

2-Cinnamamido, 2-(3-phenylpropiolamido), and 2-(3-phenylpropanamido)benzamides: synthesis, antiproliferative activity, and mechanism of action
2013
Abstract Several new benzamides 4a–q were synthesized by stirring in pyridine the acid chlorides 3a–q with the appropriate anthranilamide derivatives 2a–g. Some of the synthesized compounds were evaluated for their in vitro antiproliferative activity against a panel of 5 human cell lines (K562 human chronic myelogenous leukemia cells, MCF-7 breast cancer cells, HTC-116 and HT26 colon cancer cells and NCI H460 non-small cell lung cancer cells).
Taste perception and behavior in rodents and flies
2010
Taste, one of the five senses, plays a key role in food ingestion. The recent identification of molecular markers for taste cells (e.g., taste receptors and signaling components) has provided tools to investigate the functional organization of the gustatory system. This new information contributes to our understanding of taste-associated behaviors.
La intimidad corporal en la filosofía de Ortega y Gasset
2015
[EN] In the face of the social crisis of intimacy for the extimacy, in neurosciences, and its reduction to privacy in legal field, this article explains the orteguian idea of the intimacy highlighting its bodily character. This notion of intimacy, rooted in body, discovers the sentimental aspect of reality (lyricism), and also overcomes thingism and subjectivism through the analysis of the mechanism of metaphor and the capacity of entering yourself. Reality of intimacy is conceived as enforceability (executive reality), and represents an alternative to idealism, objetivism of conscience and psychological introspection.

Hexakis(dimethylformamide)iron(II) complex cation in hexahalorhenate(IV)-based salts: synthesis, X-ray structure and magnetic properties
2018
Two iron(II)-rhenium(IV) compounds of general formula [FeII(dmf)6][ReIVX6] [X = Cl (1) and Br (2); dmf = N,N-dimethylformamide] have been prepared and characterized. X-ray powder diffraction measurements on samples of 1 and 2 support the same structure for both systems. The crystal structure of 1 was determined by single-crystal X-ray diffraction. 1 crystallizes in the triclinic system with space group Pī. Each iron(II) is six-coordinate and bonded to six oxygens from six dmf molecules building a distorted octahedral environment. Rhenium(IV) is six-coordinate by six halide anions in an almost regular octahedral geometry. The magnetic properties were investigated from variable-temperature ma…
DNA oxidation products determined with repair endonucleases in mammalian cells: Types, basal levels and influence of cell proliferation
1999
Purified repair endonucleases such as Fpg protein, endonuclease III and IV allow a very sensitive quantification of various types of oxidative DNA modifications in mammalian cells. By means of these assays, the numbers of base modifications sensitive to Fpg protein, which include 8-hydroxyguanine (8-oxoG), were determined to be less than 0.3 per 10(6) bp in several types of untreated cultured mammalian cells and human lymphocytes and less than 10 per 10(6) bp in mitochondrial DNA from rat and porcine liver. Oxidative 5,6-dihydropyrimidine derivatives sensitive to endonuclease III and sites of base loss sensitive to endonuclease IV or exonuclease III were much less frequent than Fpg-sensitiv…
Crystal structure, magnetic and spectroscopic properties of copper(II) formato dimethylformamide: a new tetracarboxylato-bridged copper(II) dimer
2002
Abstract The crystal and molecular structure of a new tetracarboxylato copper(II) dimer [bis(dimethylformamide)tetrakis(μ-formato)dicopper(II)], has been determined by X-ray diffraction methods. The crystal structure consists of a centrosymmetric dimer [Cu2(HCOO)4(dmf)2], where four bidentate formato anions form syn–syn bridges between the metal ions which are in a 4+1 environment. Magnetic susceptibility data show that the copper ions are strongly antiferromagnetically coupled with J=−470 cm−1. The EPR spectrum shows a characteristic pattern of a triplet state with a D zero field splitting value of 0.27 cm−1.
