Impacto clínico de la telemedicina en la enfermedad de Crohn y colitis ulcerosa

2021

Introducción: Los datos de eficacia de la telemedicina en enfermedad inflamatoria intestinal (EII) no son consistentes. Se desconoce su impacto en el manejo de la EII moderada-grave. Además, no existe evidencia sobre el perfil de coste-efectividad de la telemonitorización en este contexto. Objetivos: Evaluar el impacto de la monitorización remota vía web (Telemonitorización de la Enfermedad de Crohn y Colitis Ulcerosa: TECCU) sobre las variables de salud y su perfil de coste-efectividad en pacientes con EII moderada-grave, comparado con el seguimiento presencial y el telefónico. Material y Métodos: Ensayo clínico aleatorizado con 3 grupos. Se incluyeron consecutivamente pacientes adultos de…

Aplicación clínica de la topografía de superficie de la espalda mediante luz estructurada en el screening, diagnóstico y seguimiento de las deformida…

2014

En condiciones normales la columna vertebral no presenta ninguna curvatura en el plano frontal y cuatro curvaturas fisiológicas en el plano de perfil. Existen patologías en las que se produce una alteración de estas curvaturas fisiológicas, como la escoliosis, la hipercifosis torácica y la cifoescoliosis. La escoliosis consiste en una compleja deformidad tridimensional de la columna vertebral en los tres planos del espacio, consistente en una extensión intervertebral en el plano sagital, una inclinación lateral en el plano frontal y un componente de rotación en el plano axial. La hipercifosis torácica consiste en un aumento por encima de un límite normal de la cifosis torácica fisiológica (…

Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy

2015

ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.

Caracterización bioquímica y funcional de MnmC, una proteína modificadora de tRNA de Escherichia coli

2015

En esta tesis doctoral se ha pretendido conocer aspectos bioquímicos y funcionales de la proteína bifuncional MnmC, modificadora de la U34 en algunos tRNAs del organismo Escherichia coli siempre teniendo en cuenta el marco de la ruta donde actúa (Ruta MnmEG). El primer objetivo fue clonar y expresar cada dominio de MnmC por separado para tener un sistema de estudio de las reacciones que ejercen por separado. Uno de los objetivos más importantes ha sido determinar cómo algunos de los tRNA sustratos de la ruta MnmEG son modificados por la enzima MnmC mediante un estudio comparativo de los dos dominios de la proteína y utilizando técnicas bioquímicas, genéticas y microbiólogicas para obtener d…

Regulation of type 1 fimbriae synthesis and biofilm formation by the transcriptional regulator LrhA of Escherichia coli

2005

Type 1 fimbriae ofEscherichia colifacilitate attachment to the host mucosa and promote biofilm formation on abiotic surfaces. The transcriptional regulator LrhA, which is known as a repressor of flagellar, motility and chemotaxis genes, regulates biofilm formation and expression of type 1 fimbriae. Whole-genome expression profiling revealed that inactivation oflrhAresults in an increased expression of structural components of type 1 fimbriae.In vitro, LrhA bound to the promoter regions of the twofimrecombinases (FimB and FimE) that catalyse the inversion of thefimApromoter, and to the invertible element itself. TranslationallacZfusions with these genes and quantification offimEtranscript le…

Properties of transmembrane helix TM1 of the DcuS sensor kinase of Escherichia coli, the stator for TM2 piston signaling

2021

Abstract The sensor kinase DcuS of Escherichia coli perceives extracellular fumarate by a periplasmic PASP sensor domain. Transmembrane (TM) helix TM2, present as TM2-TM2′ homo-dimer, transmits fumarate activation in a piston-slide across the membrane. The second TM helix of DcuS, TM1, is known to lack piston movement. Structural and functional properties of TM1 were analyzed. Oxidative Cys-crosslinking (CL) revealed homo-dimerization of TM1 over the complete membrane, but only the central part showed α-helical +3/+4 spacing of the CL maxima. The GALLEX bacterial two-hybrid system indicates TM1/TM1′ interaction, and the presence of a TM1-TM1′ homo-dimer is suggested. The peripheral TM1 regi…
