Supramolecular polymerization of sulfated dendritic peptide amphiphiles into multivalent L-selectin binders

2021

The synthesis of a sulfate-modified dendritic peptide amphiphile and its self-assembly into one-dimensional rod-like architectures in aqueous medium is reported. The influence of the ionic strength on the supramolecular polymerization was probed via circular dichroism spectroscopy and cryogenic transmission electron microscopy. Physiological salt concentrations efficiently screen the charges of the dendritic building block equipped with eight sulfate groups and trigger the formation of rigid supramolecular polymers. Since multivalent sulfated supramolecular structures mimic naturally occurring L-selectin ligands, the corresponding affinity was evaluated using a competitive SPR binding assay…

Distrés emocional y problemas asociados en población oncológica adulta

2017

Objetivo: en este estudio se estima la prevalencia de distrés, se identifican los problemas asociados y se analiza el conocimiento y uso que hacen los pacientes sobre los recursos psicosociales disponibles en el centro hospitalario. Método: se lleva a cabo un estudio transversal en el que participan 203 pacientes oncológicos que están recibiendo tratamiento quimioterápico. En la evaluación se emplean el Inventario de Síntomas Breve-18 (BSI-18), el Listado de Problemas de NCCN y una encuesta sobre el conocimiento y uso de los recursos asistenciales del centro hospitalario. Resultados: la prevalencia de distrés en la muestra total es del 26%. Los problemas físicos son la principal fuente de d…

Evaluación de las alteraciones psicológicas y de la calidad de vida en pacientes con cáncer colorrectal localizado

2016

En los paises desarrollados y en la mayoria del mundo industrializado, el cancer constituye uno de los mayores problemas de salud siendo una de las enfermedades mas prevalentes. En la actualidad, la estimacion en Espana sobre incidencia resalta que el cancer mas frecuente teniendo en cuenta ambos sexos, con una prevision a 5 anos, es el cancer colorrectal. El principal factor pronostico es el estadio clinico en el momento de la cirugia, pero en los ultimos anos se han desarrollado diversos programas de tratamiento adyuvante con quimioterapia y radioterapia para el cancer colorrectal. Un 70% de estos tumores son de localizacion proximal (colon), mientras que el resto son distales (recto). Es…

Cribado de distrés emocional en población oncológica adulta: validación de instrumentos

2017

La investigacion ha demostrado la presencia de niveles de distres (o malestar emocional) clinicamente significativos en aproximadamente tres de cada diez pacientes oncologicos (Mitchell et al., 2011). Sin embargo, en la actualidad, menos de la mitad de estos pacientes son identificados y derivados a los servicios de asistencia psicosocial (NCCN, 2015). El fracaso a la hora de detectar y tratar adecuadamente sus necesidades emocionales conlleva una serie de importantes consecuencias negativas que repercuten no solo en la calidad de vida de los pacientes (Shim et al., 2006) y en su nivel de satisfaccion con la atencion medica recibida (Von Essen, Larsson, Oberg y Sjoden, 2002), sino tambien e…

Evolución de la competencia comunicativa mediante intervención pragmática en retraso del lenguaje: estudio de caso

2021

En el presente trabajo se describe la eficacia de la evaluación e intervención pragmática en un caso de retraso del lenguaje secundario a daño cerebral infantil. La intervención logopédica adoptó un marco teórico de psicolingüística cognitiva funcional y se centró en potenciar las habilidades pragmáticas comunicativas mediante la estimulación de las categorías pragmáticas interactivas en contextos conversacionales naturales. Mediante el PREP-R (Protocolo Rápido de Evaluación Pragmática Revisado) se ha hecho un seguimiento de la orientación comunicativa de los turnos, la predictibilidad, la eficacia comunicativa, la habilidad pragmática (general, específica y gramatical) y los elementos que …

Problemática laboral de los socios trabajadores de las empresas de Economía Social: ¿socios o trabajadores?

1999

Co-operatives and labour societies are the most important organisations within the framework of Social Economy. The establishment of these societies, which create employment in the private sector with a democratic philosophy based on mutual help, has been recently boosted thanks to the support of public power. Their growing importance can be explained by three factors: the Employment Policy, the Social Policy and the productive decentralisation. As far as labour is concerned, these societies offer the following advantages: intensive use of labour, high rate of stability in employment, high levels of productivity, training and surplus re-inversion, lower rate of inflation, fewer conflicts th…

A Nomogram-Based Prognostic Model for Advanced Hepatocellular Carcinoma Patients Treated with Sorafenib: A Multicenter Study

2021

Simple Summary Accurate prognostic systems capable of predicting the survival of patients with advanced hepatocellular carcinoma undergoing Sorafenib therapy are still lacking. The search for the ideal predictive tool for survival and drug response is justified by the recent availability of several other drugs effective for these patients, licensed as first- and second-line treatment, other than reducing adverse events and costs. In this study, we aimed to identify simple demographic and clinical parameters able to predict survival and Sorafenib response in a large multicenter cohort. In this study, we showed that patient’s general status, liver function and damage laboratory parameters and…

A general equilibrium analysis of climate change impacts on tourism

2006

This paper studies the economic implications of climate-change-induced variations in tourism demand, using a world CGE model. The model is first re-calibrated at some future years, obtaining hypothetical benchmark equilibria, which are subsequently perturbed by shocks, simulating the effects of climate change. We portray the impact of climate change on tourism by means of two sets of shocks, occurring simultaneously. The first set of shocks translate predicted variations in tourist flows into changes of consumption preferences for domestically produced goods. The second set reallocate income across world regions, simulating the effect of higher or lower tourists' expenditure. Our analysis h…

Structure‐Activity Relationships of Benzamides and Isoindolines Designed as SARS‐CoV Protease Inhibitors Effective against SARS‐CoV‐2

2020

Abstract Inhibition of coronavirus (CoV)‐encoded papain‐like cysteine proteases (PLpro) represents an attractive strategy to treat infections by these important human pathogens. Herein we report on structure‐activity relationships (SAR) of the noncovalent active‐site directed inhibitor (R)‐5‐amino‐2‐methyl‐N‐(1‐(naphthalen‐1‐yl)ethyl) benzamide (2 b), which is known to bind into the S3 and S4 pockets of the SARS‐CoV PLpro. Moreover, we report the discovery of isoindolines as a new class of potent PLpro inhibitors. The studies also provide a deeper understanding of the binding modes of this inhibitor class. Importantly, the inhibitors were also confirmed to inhibit SARS‐CoV‐2 replication in …
