Brain Oscillatory and Hemodynamic Activity in a Bimanual Coordination Task Following Transcranial Alternating Current Stimulation (tACS): A Combined …

2018

Motor control is associated with synchronized oscillatory activity at alpha (8–12 Hz) and beta (12–30 Hz) frequencies in a cerebello-thalamo-cortical network. Previous studies demonstrated that transcranial alternating current stimulation (tACS) is capable of entraining ongoing oscillatory activity while also modulating motor control. However, the modulatory effects of tACS on both motor control and its underlying electro- and neurophysiological mechanisms remain ambiguous. Thus, the purpose of this study was to contribute to gathering neurophysiological knowledge regarding tACS effects by investigating the after-effects of 10 Hz tACS and 20 Hz tACS at parietal brain areas on bimanual coord…

Cultural Differences in Personality and Aggressive Behavior in Intimate Partner Violence Offenders

2014

Intimate partner violence (IPV) is a ubiquitous and serious problem, the prevalence of which varies greatly around the world. Previous research shows that cultural factors interact with personality and that this interaction influences cognitions, attitudes, and behaviors that are related to personal and individual styles of resolving conflicts. In relation to this, the present study has three aims: comparing the self-reported IPV (physical, psychological and sexual) of English and Spanish offenders, comparing the Millon Clinical Multiaxial Inventory III (MCMI-III) scores of the two groups, and examining the association between country of origin, psychopathology, and IPV. The sample consist…

Defining Kawasaki disease and pediatric inflammatory multisystem syndrome-temporally associated to SARS-CoV-2 infection during SARS-CoV-2 epidemic in…

2021

Abstract Background There is mounting evidence on the existence of a Pediatric Inflammatory Multisystem Syndrome-temporally associated to SARS-CoV-2 infection (PIMS-TS), sharing similarities with Kawasaki Disease (KD). The main outcome of the study were to better characterize the clinical features and the treatment response of PIMS-TS and to explore its relationship with KD determining whether KD and PIMS are two distinct entities. Methods The Rheumatology Study Group of the Italian Pediatric Society launched a survey to enroll patients diagnosed with KD (Kawasaki Disease Group – KDG) or KD-like (Kawacovid Group - KCG) disease between February 1st 2020, and May 31st 2020. Demographic, clini…

Secundo y la gran laguna en el Dialogus de oratoribus

2004

Jorge.Tarrega@uv.es El artículo examina un problema puntual en el polémico Dialogus de oratoribus: la cuestión de la gran laguna entre los capítulos 35 y 36. El autor del estudio expone una perspectiva histórica de los principales argumentos esgrimidos por la investigación sobre este asunto a lo largo, especialmente, del siglo XX. Para determinar la extensión y el contenido de la parte perdida, el análisis se estructura en torno a dos ejes: 1) la tradición manuscrita; y 2) la comparación entre el opúsculo y otros diálogos. The paper examines a specific problem in the controversial Dialogus de oratoribus: the issue of the great lacuna between chapters 35 and 36. The author of the article pla…

Vers une aide à la mobilité basée sur la connaissance de l'espace pour les personnes ayant une déficience visuelle

2018

International audience; Cette communication présente un nouveau concept de dispositif d'assistance à la mobilité pour les personnes présentant une incapacité visuelle (PPIV), son implantation dans un simulateur, et son évaluation préliminaire. Ce système, ACCESSPACE, permet de représenter l'essentiel (gist) de l'agencement spatial des alentours immédiats de l'utilisateur, sur une tablette à stimulation tactile. En combinant des données cartographiques, GPS et visuelles, ce système effectue un bi-partitionnement de l'espace (en zones accessibles ou non) et transmet cette information sous forme d'une carte égocentrée augmentée, évoluant en temps réel avec les mouvements de l'utilisateur. L'év…

Atrial Fibrosis Hampers Non-invasive Localization of Atrial Ectopic Foci From Multi-Electrode Signals: A 3D Simulation Study

2018

[EN] Introduction: Focal atrial tachycardia is commonly treated by radio frequency ablation with an acceptable long-term success. Although the location of ectopic foci tends to appear in specific hot-spots, they can be located virtually in any atrial region. Multi-electrode surface ECG systems allow acquiring dense body surface potential maps (BSPM) for non-invasive therapy planning of cardiac arrhythmia. However, the activation of the atria could be affected by fibrosis and therefore biomarkers based on BSPM need to take these effects into account. We aim to analyze the effect of fibrosis on a BSPM derived index, and its potential application to predict the location of ectopic foci in the …

Understanding of tactile pictures in visual impaired children

2015

The present PhD aims at understanding how Visual Impaired (VI) children process the tactile pictures that illustrate the tactile books specially designed for them. Our work is organized around two main axes of analysis. The first axis concentrates on the child who explores the tactile images, while the second axis focuses on the impact that the properties of these images can have on children’s haptic processing. Our researches included children presenting various degrees of visual impairment but without any associated disorders (in particular, without any cognitive delay), distinguishing early blind children from children with low vision. We also compared their performance with those of sig…

Objective: Growth differentiation factor-8 (GDF8), also known as myostatin, is a member of the transforming growth factor-β superfamily that inhibits skeletal muscle growth. We aimed to investigate the association between GDF8 and peak troponin I levels after acute myocardial infarction (AMI). Methods: All consecutive patients admitted from June 2016 to February 2018 for type 1 AMI in the Coronary Care Unit of University Hospital of Dijon Bourgogne (France) were included in our prospective study. Blood samples were harvested on admission, and serum levels of GDF8 were measured using a commercially available enzyme-linked immunosorbent assay kit. Results: Among the 296 patients with type 1 A…

Ventricular Fibrillation and Tachycardia Detection Using Features Derived from Topological Data Analysis

2022

A rapid and accurate detection of ventricular arrhythmias is essential to take appropriate therapeutic actions when cardiac arrhythmias occur. Furthermore, the accurate discrimination between arrhythmias is also important, provided that the required shocking therapy would not be the same. In this work, the main novelty is the use of the mathematical method known as Topological Data Analysis (TDA) to generate new types of features which can contribute to the improvement of the detection and classification performance of cardiac arrhythmias such as Ventricular Fibrillation (VF) and Ventricular Tachycardia (VT). The electrocardiographic (ECG) signals used for this evaluation were obtained from…
