Normes d’associations verbales pour 520 mots concrets et étude de leurs relations avec d’autres variables psycholinguistiques
2013
Resume Cet article presente un nouvel ensemble de normes d’associations verbales pour 520 noms concrets du francais. Les normes d’associations verbales sont utiles pour l’etude des processus fondamentaux et representations en jeu dans les habiletes memorielles, de comprehension et production du langage. Les relations qu’entretiennent les normes d’associations verbales avec d’autres variables psycholinguistiques sont analysees. Aussi la stabilite des normes d’associations verbales a-t-elle ete etudiee sur un sous-ensemble de mots de l’etude de Ferrand et Alario (1998). Parmi les principaux resultats, il apparait que : 1. les items se repartissent en trois grands ensembles relativement distin…
AN EFFECTIVE NEUROFEEDBACK TRAINING, WITH CORTISOL CORRELATES, IN A CLINICAL CASE OF ANXIETY
2017
Background and objectives: Neurofeedback treatments have shown successful results in anxiety disorders. Thus, the effectiveness of a beta1 Neurofeedback protocol was tested in a longitudinal clinical case study. Design and methods: A participant suffering from an anxiety syndrome was treated with 10 sessions of Neurofeedback, which protocol consisted in uptraining beta1 rhythm (16-21 Hz) while downtraining theta (4-8 Hz) band. For each of the 10 sessions the state anxiety and salivary cortisol levels were measured in a pre/post design. Initial and final examinations of anxiety symptoms and sustained attention performance were taken in addition. 
 Results: The final evaluation showed th…
Analysis of the differences in serve effectiveness between Billie Jean King Cup (former Fed Cup) and Davis Cup doubles tennis matches
2021
The doubles game has considerable relevance in professional tennis, especially in team competitions such as the Billie Jean King Cup (former Fed Cup) (BJKC) and the Davis Cup (DC). However, there are very few studies that have carried out quantitative notational analysis to provide information on the specific features of this tennis modality. The goal of this study was to analyse the differences in serve direction and effectiveness of male and female teams in matches played at BJKC and DC ties. A total of 29,207 serves; 7,578 of BJKC and 21,628 of DC matches were analysed. The data was obtained through the Hawk-Eye system. The results showed that with the first serve, both BJKC and DC team…
Los pies y el envejecimiento: efectos sobre el equilibrio estático y dinámico
2020
Resumen La acumulacion de los efectos del envejecimiento fisiologico y patologico puede tener consecuencias desastrosas sobre la funcion de equilibrio y la locomocion. Las personas debilitadas pueden entrar de repente en una fase de descompensacion postural a consecuencia de una lesion aparentemente benigna del pie, la cual, sin embargo, puede tener una repercusion funcional considerable. Conocer los efectos principales del envejecimiento en el segmento distal del miembro inferior asi como el papel del tobillo y el pie en la regulacion postural son elementos fundamentales para establecer las bases de la rehabilitacion. Situaciones funcionales como el pie doloroso, el pie rigido, el pie trof…
Gender, Coping, and Mental Health: a Bayesian Network Model Analysis
2016
We examined the relationships among gender, coping, and mental health in terms of probabilities. We selected a sample of university students (N = 131) aged between 18 and 32 years, and used the GHQ-28 and COPE instruments for analysis. The Bayesian network model that we constructed showed higher probabilities of symptoms of mental health problems for emotion-focused coping than for problem-focused coping. No differences were found regarding gender. This suggests that the use of problem-focused coping is more recommendable for both male and female university students, and it may also provide some benefits in terms of treatment of symptoms of mental health problems. However, to further verify…
Reconnaissance de l’émotion faciale et schizophrénie
2009
Resume La schizophrenie se caracterise par une large gamme de deficits dans les competences interpersonnelles. Une maniere d’aborder ces deficits consiste naturellement a explorer la capacite des patients schizophrenes a traiter des stimuli dont l’importance psychosociale est averee : les visages, par exemple. Il est aujourd’hui admis que les patients schizophrenes souffrent de difficultes importantes en matiere de reconnaissance et de discrimination faciales. Ces difficultes ont ete mises en evidence dans des paradigmes varies, incluant des tests de reconnaissance d’identite, d’emotion ou d’âge. L’etendue de ces troubles suggere l’alteration d’un mecanisme de traitement commun a tous les t…
Olfaction, émotions et comportements
2015
International audience; Le nez a ses raisons que la raison ignore. Les émotions olfactives sont souvent inconscientes et vont pourtant diriger nombreux de nos comportements. Ce lien étroit entre émotion et olfaction est dû au fait que certaines régions cérébrales sont à la fois impliquées dans les processus olfactifs et émotionnels (cortex frontal et amygdale). Dans les pathologies neurodégénératives, dont la maladie d’Alzheimer (MA), ces structures vont être atteintes à des stades plus ou moins sévères de la maladie. Au-delà d’une aide au diagnostic précoce, nous avons montré que l’utilisation d’odorants pourrait aider au diagnostic différentiel entre certains troubles de l’humeur et la ma…
Cognate HLA absence in trans diminishes human NK cell education
2016
NK cells are innate lymphocytes with protective functions against viral infections and tumor formation. Human NK cells carry inhibitory killer cell Ig-like receptors (KIRs), which recognize distinct HLAs. NK cells with KIRs for self-HLA molecules acquire superior cytotoxicity against HLA– tumor cells during education for improved missing-self recognition. Here, we reconstituted mice with human hematopoietic cells from donors with homozygous KIR ligands or with a mix of hematopoietic cells from these homozygous donors, allowing assessment of the resulting KIR repertoire and NK cell education. We found that co-reconstitution with 2 KIR ligand–mismatched compartments did not alter the frequenc…
Effect of Host Species on Topography of the Fitness Landscape for a Plant RNA Virus
2016
[EN] Adaptive fitness landscapes are a fundamental concept in evolutionary biology that relate the genotype of individuals with their fitness. At the end, the evolutionary fate of evolving populations depends on the topography of the landscape, that is, the number of accessible mutational pathways and of possible fitness peaks (i.e, adaptive solutions). For long time, fitness landscapes were only theoretical constructions due to a lack of precise information on the mapping between genotypes and phenotypes. In recent years, however, efforts have been devoted to characterize the properties of empirical fitness landscapes for individual proteins or for microbes adapting to artificial environme…
Indicaxanthin from Opuntia Ficus Indica (L. Mill) impairs melanoma cell proliferation, invasiveness, and tumor progression.
2018
Abstract Background: A strong, reciprocal crosstalk between inflammation and melanoma has rigorously been demonstrated in recent years, showing how crucial is a pro-inflammatory microenvironment to drive therapy resistance and metastasis. Purpose: We investigated on the effects of Indicaxanthin, a novel, anti-inflammatory and bioavailable phytochemical from Opuntia Ficus Indica fruits, against human melanoma both in vitro and in vivo. Study Design and Methods: The effects of indicaxanthin were evaluated against the proliferation of A375 human melanoma cell line and in a mice model of cutaneous melanoma. Cell proliferation was assessed by MTT assay, apoptosis by Annexin V-Fluorescein Isothio…
