Tris(cyclo-hexyl-ammonium) cis-di-chlorido-bis-(oxalato-κ(2) O (1),O (2))stann-ate(IV) chloride monohydrate.

2013

The crystal structure of the title compound, (C6H14N)3[Sn(C2O4)2Cl2]Cl·H2O, contains three cyclohexylammonium cations, one stannate(IV) dianion, one isolated chloride anion and one lattice water molecule. The cyclohexylammonium cations adopt chair conformations. In the complex anion, two bidentate oxalate ligands and two chloride anions incispositions coordinate octahedrally to the central SnIVatom. The cohesion of the molecular entities is ensured by the formation of N—H...O, O—H...O, O—H...Cl and N—H...Cl interactions involving cations, anions and the lattice water molecule, giving rise to a layer-like arrangement parallel to (010).

Synthesis and copper-mediated nuclease activity of a tetracationic tris(2,2′-bipyridine) ligand

2009

Abstract We report herein the synthesis of a novel tetracationic tris(2,2′-bipyridine) ligand 4 . We show that this ligand metalated with copper(II), and in the presence of ascorbate as a reducing agent, strongly damages pUC18 plasmid DNA. Copper complex formation was demonstrated by ESI-MS (electrospray ionization-mass spectrum) at a 1:3 ligand to metal ratio. Binding of both 4 and its copper(II) complex to CT-DNA (calf thymus DNA) was characterized by viscosimetry, thermal denaturation and fluorescence-based competition assays. The viscosimetric data indicated that 4 and its copper(II) complex bind DNA through partial intercalation and thermal denaturation studies revealed a significant i…

Dirhodium(II) compounds with bridging thienylphosphines: studies on reversible P,C/P,S coordination.

2009

Monocyclometalated compound [Rh(2){(C(8)H(4)S)P(C(8)H(5)S)(2)}(CH(3)CO(2)H)(2)(O(2)CCH(3))(3)] (1 a) and bis-cyclometalated compound [Rh(2){(C(8)H(4)S)P(C(8)H(5)S)(2)}(2)(CH(3)CO(2)H)(2)(O(2)CCH(3))(2)] (2 a) have been isolated from the reaction of dirhodium tetraacetate and tris(2-benzo[b]thienyl)phosphine (2 BTP) using low acidic solutions. By contrast, in pure acetic acid the reaction of Rh(2)(O(2)CCH(3))(4) with 2 BTP and tris(2-thienyl)phosphine (2 TP), followed by replacement of the axial acetate ligands by chlorides, led to [Rh(2){(2-C(8)H(5)S)P(2-C(8)H(5)S)(2)}(2)Cl(2)(O(2)CCH(3))(2)] (3 b) and [Rh(2){(2-C(4)H(3)S)P(C(4)H(3)S)(2)}(2)Cl(2)(O(2)CCH(3))(2)] (5 b), respectively. These n…

MMP-10/stromelysin-2 promotes invasion of head and neck cancer.

2011

BackgroundPeriostin, IFN-induced transmembrane protein 1 (IFITM1) and Wingless-type MMTV integration site family, member 5B (Wnt-5b) were previously identified as the invasion promoted genes of head and neck squamous cell carcinoma (HNSCC) by comparing the gene expression profiles between parent and a highly invasive clone. We have previously reported that Periostin and IFITM1 promoted the invasion of HNSCC cells. Here we demonstrated that Wnt-5b overexpression promoted the invasion of HNSCC cells. Moreover, stromelysin-2 (matrix metalloproteinase-10; MMP-10) was identified as a common up-regulated gene among Periostin, IFITM1 and Wnt-5b overexpressing HNSCC cells by using microarray data s…

Valoración del manejo de los inhaladores por el personal de enfermería en un hospital de referencia

2008

Objetivo: valorar los conocimientos y adiestramiento del personal de enfermería con el paciente respiratorio en el manejo de la terapia inhalada en distintas salas de hospitalización. Material y métodos: se diseñó un estudio prospectivo con 144 enfermos/as mediante una encuesta individual en la que se solicitó a cada uno de ellos una demostración práctica del manejo del cartucho presurizado con cámara inhalatoria, sin realizar una instrucción teórica previa sobre la técnica. Se revisó la técnica inhalatoria siguiendo los pasos establecidos en la normativa SEPAR. Resultados: participaron 144 de los 177 enfermeros/as (81,4%) que trabajan en las diferentes salas de hospitalización (29 varones,…

From Undetectable Equals Untransmittable (U=U) to Breastfeeding: Is the Jump Short?

2022

Background: Vertical transmission of HIV infection may occur during pregnancy, at childbirth or through breastfeeding. Recommendations on the safety of breastfeeding of HIV-infected women on effective antiretroviral treatment are not univocal among international guidelines (WHO 2010, EACS 2017, DHHS 2017), leaving space for variability at the patient’s level. Methods: We collected clinical, laboratory and outcome data from 13 HIV-infected pregnant women who, between March 2017 and June 2021, elected to breastfeed their children against specific medical advice. All mothers were on antiretroviral therapy with darunavir or raltegravir plus emtricitabine/tenofovir disoproxil and remained HIV-RN…

Evaluación de la técnica quirúrgica de implantación de neuroestimulador a nivel del ganglio esfenopalatino para el tratamiento de las cefaleas crónic…

2017

- Estado actual del conocimiento El ganglio esfenopalatino (GEP), situado en la fosa pterigopalatina, es una estructura anatómica compleja que ha sido reconocida como la mayor agrupación de neuronas fuera de la cavidad craneana. No posee función sensitiva, sin embargo tiene gran relación y conexiones con múltiples ramas faciales y trigeminales, por lo que se cree que interviene en la génesis y mantenimiento de dolores faciales atípicos y cefaleas unilaterales de tipo autonómico trigeminal. El GEP contiene fibras autonómicas, tanto simpáticas como parasimpáticas. Debido a ello se ha seleccionado como estructura diana en los estudios de neuroestimulación. Existen muchas técnicas intervencioni…
