Stability in physiological saline of intravenous busulfan in a polyolefin pack
2008
Abstract Introduction Although it has been used orally, the variability in its absorption and the risk of causing vomiting has lead to a push towards the intravenous use of busulfan. This study looks at the stability of 60 mg of busulfan, in fixed volumes of 250 mL (0.24 mg/mL) and 500 mL (0.12 mg/mL) of physiological saline and different conservation conditions, in a new plastic pack made from polyolefin/polyamide laminates. Material and methods High-performance liquid chromatography with ultraviolet detection was used to determine the concentration of busulfan derivate with sodium diethyldithiocarbamate trihydrate. Stability was assessed for both concentrations; refrigerated and at room t…

Análisis del discurso político de Barack H. Obama desde la perspectiva lingüística discursiva de George Lakoff: Elecciones 2008
2015
El objetivo fundamental de esta tesis doctoral es comprobar la viabilidad, adecuación y eficacia de la aplicación de los supuestos de las tesis lingüístico-cognitivas de Lakoff (2002, 2004, 2006, 2007, 2008a, 2008b) al ámbito de los discursos políticos entendidos como construcciones textuales y representaciones del mundo que proponen y defienden, a modo de marcos y a través de unos recursos específicos tal como las metáforas, los partidos políticos (republicano y demócrata) norteamericanos. El paradigma que rige el proceso de investigación puede definirse como lingüístico-cognitivo dentro de la versión específica que desarrolla Lakoff en sus trabajos de carácter propiamente lingüístico y, m…
Synthesis and structural studies on Ni(II) dithiocarbamates : Exploring intramolecular Ni···H-C interactions
2017
Five new Ni(II) dithiocarbamates with NiS4, NiS2PN and NiS2PCl coordination spheres, viz. [Ni(bupmbzdtc)2] (1), [Ni(bupmbzdtc)(PPh3)(NCS)] (2), [Ni(bupmbzdtc)(PPh3)Cl] (3), [Ni(4-dpmpzdtc)(PPh3)Cl] (4) and [Ni(pbbzbudtc)(PPh3)(NCS)] (5), where bupmbzdtc = N-butyl(p-methylbenzyl)dithiocarbamato anion, 4-dpmpzdtc = 4-(diphenylmethyl)piperazinecarbodithioato anion, pbbzbudtc = N-(p-bromobenzyl)butyl-dithiocarbamato anion and PPh3 = triphenylphosphine, were synthesized and characterized by UV, IR, NMR and single crystal X-ray diffraction methods. Spectral results suggest a square planar geometry around the Ni(II) metal center for all the synthesized complexes. Single crystal X-ray structural an…
Synthesis of Both Ionic Species of Ammonium Dithiocarbamate Derived Cholic Acid Moieties
2011
The reaction of 3-aminopropylamide of cholic acid with CS₂ produced a bile acid derivative of dithiocarbamic acid which further formed an ammonium salt with another molecule of 3-aminopropylamide of cholic acid. The cationic 3-ammonium propylamide of cholic acid did not react further with CS₂ and the formed salt was stable in the reaction mixture, even when excess CS₂ was used. When the reaction was carried out in the presence of aqueous sodium hydroxide, only the bile acid derivative of sodium dithiocarbamate was formed. The dithiocarbamate derivatives were characterized by ¹H- and ¹³C-NMR spectroscopy and ESI-TOF mass spectrometry. peerReviewed
Cobalt content of foods and diets in a Spanish population
1986
The WHO Expert Committee on Food Contaminants has pointed out the need of determining the content of foods in trace elements in order to ascertain their contribution to the total intake of oligoelements through the diet. Since the contents in trace elements depend on the environmental features, it is necessary to carry out systematic determinations of trace elements in foods of local origin in order to know the exposure level of population. This work intends to study the cobalt contribution through the diet. The element intake is calculated from the cobalt content in raw foods after elimination of the non-eatable moiety by flame atomic absorption spectroscopy, after formation of a chelate w…
Role of glutathione in Thiobencarb resistance in the European eel Anguilla anguilla.
2000
Glutathione-dependent defense against xenobiotic toxicity is a multifaceted phenomenon that has been well characterized in mammals. In the present study, eels of species Anguilla anguilla were exposed to 15 ppm of the herbicide thiobencarb (S-4-chlorobenzyl diethylthiocarbamate) for 96 h. Eels exposed to the pesticide were grouped in 24-h intervals according to their time of death, while surviving intoxicated eels constituted another group (live animals). Glutathione content (GSx, GSH, GSSG) was determined in liver and muscle tissues of the dead and live (intoxicated) animals and compared to control values (nonexposed eels). The fish that died before 96 h of exposure were considered suscept…
Estudio y modulación del metabolismo del glutatión en la tolerancia al estrés oxidativo generado por plaguicidas en organismos acuáticos de interés c…
2003
La utilización de plaguicidas para el cultivo del arroz en campos cercanos a humedales de gran valor ecológico como los Parques Naturales de la Albufera de Valencia y el Delta del Ebro (Tarragona) suponen un riesgo no sólo para los ecosistemas de estos Parques sino también para la pesca y acuicultura que se desarrolla en la zona. La anguila europea (Anguilla anguilla) reside en ambos hábitats y está expuesta a cantidades considerables de herbicidas tiocarbamatos como el molinato y tiobencarb. Estos plaguicidas disminuyen y oxidan los niveles del antioxidante intracelular más importante, el glutatión (GSH). Así, se ha descubierto que el principal mecanismo de toxicidad de los herbicidas tioc…

Grazoprevir/elbasvir for the immediate treatment of recently acquired HCV genotype 1 or 4 infection in MSM.
2020
Abstract Background In Europe, increases in HCV infection have been observed over the last two decades in MSM, making them a key population for recently acquired HCV. Alternative combinations of direct-acting antiviral agents against early HCV infection need to be assessed. Patients and methods In this pilot trial, MSM with recently acquired genotype 1 or 4 HCV infection were prospectively included and received 8 weeks of oral grazoprevir 100 mg and elbasvir 50 mg in a fixed-dose combination administered once daily. The primary endpoint was sustained virological response evaluated 12 weeks after the end of treatment (EOT) (SVR12). Secondary endpoints were the virological characterization of…
