On the role of the triplet state in the cis/trans isomerization of rhodopsin: A CASPT2//CASSCF study of a model chromophore
2011
The possibility of population of the lowest-lying triplet state (T1) in the early events of the photochemical isomerization process of a model chromophore of Rhodopsin (Rh) has been analyzed using multireference perturbation theory (CASPT2//CASSCF) methods. It is shown that the characteristics of the isomerization process namely small S1−T1 gap, presence of hydrogen out of plane active vibrational modes, and existence of a dense manifold of vibrational states, render possible the fulfilment of the conditions needed for the population of T1. The possible consequences for the photochemistry and photophysics of Rh are also discussed. © 2011 Wiley Periodicals, Inc. Int J Quantum Chem 111:3431–3…
Modelling drift of pelagic offspring: the importance of egg surveys in providing a realistic model initialization
2015
Abstract Having valid information about the location and dynamics of biological processes is important for coastal management. In this context modelling, the pelagic drift of early life stages has been shown to be an important tool for understanding the spatial scale of population dynamics in marine systems. Often simulated particles are released in hypothetical quantities at assumed spawning grounds with no or few field data to guide the model parametrization. In this study, we combine high-resolution field data and state-of-the-art oceanographic modelling and use a probabilistic approach to construct kernel density distributions of the dispersal of pelagic fish eggs. Specifically, the pot…
Early Treatment in HCV: Is it a Cost-Effective Option from the Italian Perspective?
2016
Background: The aim of this study is to perform an economic analysis to estimate the cost-utility of the early innovative therapy in Italy for managing HCV-infected patients.Methods: The incremental cost-utility analysis was carried out to quantify the benefits of the early treatment approach in HCV subjects. A Markov simulation model including direct and indirect costs and health outcomes was developed from Italian National Healthcare Service and societal perspective. 5,000 Monte Carlo simulations were performed on two distinct scenarios: Standard of Care (SoC) which includes 14.000 Genotype 1 patients in Italy treated with innovative interferon-free in the Fibrosis stage 3 and 4 (F3-F4) v…
New Technique in Tendon Sport Recovery. Percutaneous Electrolysis Intratissue (EPI®)
2013
Based on the literature and clinical experience we know that the technique of percutaneous electrolysis intratissue (EPI ® ) has positive effects on the recovery of human tendinopathies. The application of the technique, together with the completion of eccentric exercise, give benefits leading to anatomical and functional recovery in the tendon that can be appreciated by ultrasound using the scale of "Victorian Institute of Sport Assessment-patellar tendon" (VISA-P). Due to clinical knowledge, damage to tendon is accompanied by increase in oxidative stress, cell death and inflammation at the damaged area. The EPI ® technique produced a galvanic current inside the tendon, with an acupuncture…

Disparités géographiques et convergence des régions européennes : une approche par l'économétrie spatiale
2002
The aim of this dissertation is to analyze the convergence process between European regions by taking into account spatial patterns of economic activities. First, with the help of literature reviews on theoretical and empirical analyses of growth and convergence and on economic geography models, we show in chapter 1 why geographic disparities should be introduced in the study of convergence between economies. Next, the spatial statistic and econometric tools allowing to reach this goal are detailed in chapter 2. Finally, three empirical studies of the convergence process in presence of geographic disparities are carried out. They are based on a sample for per capita GDP of 138 regions, belo…

Innovative extraction and separation technologies to improve the recovery of microalgae nutrients and bioactive compounds with potential beneficial e…
2023
Las microalgas son ricas en una gran variedad de compuestos bioactivos, que incluyen proteínas, polifenoles, polisacáridos, pigmentos, minerales, vitaminas, etc., que pueden utilizarse o separarse directamente para obtener componentes de mayor valor. La extracción y la separación son pasos clave en la obtención y posterior procesamiento de los productos relacionados con las microalgas, representando las tecnologías innovadoras de procesado una estrategia innovadora y eficiente para mejorar la calidad de estos productos. Actualmente, las microalgas y sus compuestos (nutrientes, compuestos bioactivos, etc.) se utilizan como alimento y también con finalidades desde el punto de vista de salud, …
Estudio Clínico para comparar la eficacia y tolerabilidad de la utilización de velos electrohilados para el tratamiento de pacientes quemados
2023
Introducción: El gold standard del tratamiento quirúrgico de las quemaduras son los autoinjertos de piel parcial. En estudios preclínicos, el uso de un biovelo de ácido poli(láctico-co-glicólico) (PLGA) electrohilado, colocado entre los autoinjertos y su lecho, ha demostrado su potencial para estimular la regeneración dérmica, aumentando el prendimiento y mejorando la calidad de la cicatriz. Adicionalmente, la estructura tridimensional del biovelo y su biodegradabilidad, le confieren un potencial uso como vía de administración de terapias locales. Estas propiedades no han sido todavía evaluadas en ensayos clínicos en humanos. Objetivo: El objetivo principal de este estudio fue comparar intr…
