Orbitotomía supero medial: nuevos límites en el abordaje endonasal expandido transetmoidal

2015

Introducción: Los límites de los abordajes endonasales endoscópicos expandidos (AEEE) no están delimitados y continúan en constante evolución. El límite de la extensión lateral en el plano coronal del AEEE transetmoidal descrito hasta el momento viene determinado por la unión del techo de las fóveas etmoidales con la lámina papirácea. Objetivos: Este trabajo se basa en la hipótesis fundamental de que la resección de lesiones situadas en la base craneal anterior, concretamente en la porción formada por el hueso frontal y asentadas más allá de las láminas papiráceas, pueden ser abordadas de forma completamente endonasal endoscópica. La hipótesis operativa considera que es posible mediante la …

Wsparcie i radzenie sobie ze stresem jako moderatory związku stresu i jakości życia osób transpłciowych

2018

This study was conducted in order to verify the role of social support and coping strategies as moderators of the relationship between perceived stress and the subjective well-being of transgender people, which is lower than cisgenders’ people. 355 people took part in this study (124 transgender people and 231 cisgender people) between age of 18 and 53. Subjective well-being has been operationalized using the Satisfaction With life Scale SWLS. Measurement of the perceived stress was made using the Perceived Stress Scale PSS-10. Coping strategies were examined using the Mini-COPE inventory. Additionally, two subscales of the Berlin Social Support Scales BSSS were used to measure received and…

Erosion, screening, and migration of tungsten in the JET divertor

2019

The erosion of tungsten (W), induced by the bombardment of plasma and impurity particles, determines the lifetime of plasma-facing components as well as impacting on plasma performance by the influx of W into the confined region. The screening of W by the divertor and the transport of W in the plasma determines largely the W content in the plasma core, but the W source strength itself has a vital impact on this process. The JET tokamak experiment provides access to a large set of W erosion-determining parameters and permits a detailed description of the W source in the divertor closest to the ITER one: (i) effective sputtering yields and fluxes as function of impact energy of intrinsic (Be,…

Patterning of supported gold monolayers via chemical lift-off lithography

2017

The supported monolayer of Au that accompanies alkanethiolate molecules removed by polymer stamps during chemical lift-off lithography is a scarcely studied hybrid material. We show that these Au–alkanethiolate layers on poly(dimethylsiloxane) (PDMS) are transparent, functional, hybrid interfaces that can be patterned over nanometer, micrometer, and millimeter length scales. Unlike other ultrathin Au films and nanoparticles, lifted-off Au–alkanethiolate thin films lack a measurable optical signature. We therefore devised fabrication, characterization, and simulation strategies by which to interrogate the nanoscale structure, chemical functionality, stoichiometry, and spectral signature of t…

Using Heart Rate Variability Methods for Health-Related Outcomes in Outdoor Contexts : A Scoping Review of Empirical Studies

2023

Heart rate variability (HRV) is a psychophysiological variable that is often used in applied analysis techniques to indicate health status because it provides a window into the intrinsic regulation of the autonomic nervous system. However, HRV data analysis methods are varied and complex, which has led to different approaches to data collection, analysis, and interpretation of results. Our scoping review aimed to explore the diverse use of HRV methods in studies designed to assess health outcomes in outdoor free-living contexts. Four database indexes were searched, which resulted in the identification of 17,505 candidate studies. There were 34 studies and eight systematic reviews that met t…

Uniportal bilateral video-assisted sequential thoracoscopic extended thymectomy

2017

Standard video-assisted thoracoscopic surgery has been reported as a minimally invasive approach alternative to sternotomy for management of myasthenia gravis (MG) associated with thymoma or thymic hyperplasia. Uniportal video-thoracoscopy is an evolution of standard multi-portal video-thoracoscopy for management of several thoracic diseases but its role for resecting mediastinal tumor remains under-evaluated. Herein, we describe our experience with bilateral uniportal thoracoscopic sequential extended thymectomy with case and video illustrations.

Dual Enzyme-Triggered Controlled Release on Capped Nanometric Silica Mesoporous Supports

2012

The development of nanoscopic hybrid materials equipped with “molecular gates” showing the ability of releasing target entrapped guests upon the application of an external trigger has attracted great attention and has been extensively explored during recent years.1 These nanodevices are composed of two subunits, namely, a suitable support and certain capping entities grafted on the surface of the scaffolding.2 The support is used as a suitable reservoir in which certain chemicals can be stored whereas the molecules grafted in the outer surface act as a “gate” and can control the release of the entrapped molecules at will. Both components are carefully selected and arranged in order to achie…

Il ruolo della famiglia e delle modalità di problem solving nell’utilizzo di alcol tra gli adolescenti.

2012

Introduzione L’abuso di alcol è uno dei principali problemi in Italia, soprattutto se si considera la sua incidenza tra i più giovani. In letteratura, vi è la tendenza a descrivere quattro diverse categorie di bevitori tra gli adolescenti: non bevitori, bevitori sociali, binge e heavy drinker (D'Alessio, et al., 2006). Fattori di rischio psicosociali connessi con l’uso di alcol sono oggi considerati le strategie di coping evitanti e il funzionamento familiare. Scopo della presente ricerca è quello di valutare l’impatto di queste variabili sull’insorgenza di abuso di alcol in adolescenza. Metodo Hanno preso parte alla ricerca 930 adolescenti tra i 14 e i 17 anni. Ai soggetti sono stati sommi…

Resilience and the Aging Process: Assessment Tools and Needs

2015

Abstract Successful resilience is a variable often related to an optimal aging process and that might have a role on education. However, literature is rather limited when dealing with assessment instruments for the elderly in the Spanish language. The objective of this work is to examine the Brief Resilient Coping Scale (Sinclair &Wallston, 2004), a four item likert scale, in the Spanish elderly. This scale was administrated to a sample of 920 elderly Spanish participants, and the data set analysed in terms of exploratory and confirmatory factor analysis and internal consistency. The scale demonstrated good psychometric properties. Furthermore, the homogeneity indices were higher than in th…
