Ethanol intake in male mice exposed to social defeat: Environmental enrichment potentiates resilience
2021
Large preclinical evidence shows that exposure to social defeat (SD) increases vulnerability to drug abuse, increasing the consumption of ethanol. However, not all subjects are equally affected by the changes induced by stress. Previous reports have evidenced that the resilient phenotype to depressive-like behaviors after SD is associated with the resistant phenotype to cocaine-increased rewarding effects and the smaller neuroinflammatory response. The aim of the present study was to further clarify whether the resilient profile to depressive-like behavior also predicts a protection against the increase in ethanol intake induced by SD. The neuroinflammatory profile was studied after the end…
Enriched Environments for Rodents and their Interaction with Nicotine Administration
2012
An active lifestyle throughout the life cycle seems to delay cognitive aging and dementia and has also been evaluated as an intervention against addiction to cocaine and other drugs of abuse. In epidemiological studies with humans, it has proved difficult to separate the cognitive, social and physical components from other variables that influence lifestyle. Studies in animal models are useful for evaluating the impact of each of these factors and for uncovering the underlying mechanisms of the benefits of complex environments. Preclinical studies have employed the Environmental Enrichment paradigm (EE) which has been proposed as a preclinical model of positive life experiences in humans. E…
Individual Differences in Novelty-Seeking and Behavioral Responses to Nicotine: A Review of Animal Studies
2010
Individual differences in the behavioral responses to a novel environment have been proposed as a research tool to predict responsiveness to other behavioral tasks, response to certain events and individual vulnerability to nicotine addiction. In rats and mice, novelty seeking (defined as enhanced specific exploration of novel situations) is a complex behavior confirmed by a large body of neurochemical, endocrinological and behavioral data. We review the main standardized procedures employed to measure the novelty seeking trait in rodents and the ontogeny of this behavior throughout the life-span taking into account that novelty seeking can be permanently modified as a consequence of partic…
A catalytic highly enantioselective direct synthesis of 2-bromo-2-nitroalkan-1-ols through a Henry reaction.
2008
Highly enantiomerically enriched 2-bromo-2-nitroalkan-1-ols are prepared by direct condensation of aliphatic and aromatic aldehydes with bromonitromethane in the presence of a catalytic amount of copper(II) acetate and a C1-symmetric camphorderived amino pyridine ligand.

GRAPH-BASED RULES FOR XML DATA CONVERSION TO OWL ONTOLOGY
2010
International audience; The paper presents a flexible method to enrich and populate an existing OWL ontology from XML data based on graph-based rules. These rules are defined in order to populate automatically a new version of an OWL ontology. Today, most of data exchanged between information systems is done with the help of the XML document. Leading researches in the domain of database systems are moving to semantic model in order to store data and its semantics definition. This flexible method consists in populating an existing OWL ontology from XML data. In paper we present such a method based on the definition of a graph which represents rules that drive the populating process.
Query expansion and semantic visualization in information system cooperations : methods and tools for information retrieval
2010
This thesis presents approaches and tools for information retrieval. Our work is part of a cooperation system based on ontologies called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). We treat the problem of information retrieval by providing an enrichment method called QUEXME (QUery EXpansion MEthod) of queries based on analysis of user behavior and using the concept importance notion with regards to query. We also discussed the problem of visualization in the OWSCIS system offering a architecture of service visualization. It is composed of three modules: the request, enrichment and results. The approaches proposed in this thesis have been prototyped and the te…
A model of high performance work practices and turnover intentions
2007
– This paper aims to clarify the relationship between human resource practices and staff retention by selecting three high performance work practices (precursors) and one outcome variable (turnover intentions), and trying to demonstrate the mediator role of employee commitment and job satisfaction in this relationship., – The proposed model has been analyzed with a sample of 198 employees and a structural equation modeling methodology., – Salary strategies and job enrichment strategies were positively related to job satisfaction. Job enrichment strategies and job stability strategies were positively related to employee commitment. Employee commitment was negatively related to turnover inten…
Redesigning work in university classrooms: factors related to satisfaction in engineering and business administration students
2014
Objeto: Con este trabajo se pretende analizar cómo afectan las características del contexto del aprendizaje, es decir, cómo es el trabajo de los estudiantes en la asignatura, al potencial motivador de la asignatura y a la satisfacción de los estudiantes. Diseño/metodología/enfoque: Mediante ecuaciones estructurales (SEM) se ha analizado los datos de una muestra transversal (cursos 2008, 2009 y 2010) de 535 estudiantes de ingeniería industrial y administración de empresas, de una universidad pública española. Aportaciones y resultados: Los resultados, utilizando un instrumento validado y adaptado al mundo docente, demuestran la asociación existente entre las características del tipo de traba…
