ORBi Open Repository and Bibliography
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision).
This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.
Vocal impact of a prolonged reading task at two intensity levels : Perceptual analysis - Remacle, Angélique; FINCK, Camille; Schoentgen, Jean; Bodson, Agnès; Morsomme, Dominique
Our goal is to evaluate the impact on voice of both duration and intensity level of 2 hours of continuous oral reading. Fifty normophonic women underwent two sessions of voice loading in which the required intensity level of voice varied: 60-65 dB(A) for the first session, and 70-75 dB(A) for the second session. Objective measurements and subjective self-ratings were presented in a previous study (Remacle, Finck, Roche & Morsomme, 2012). Here are the results of perceptual analysis based on comparative judgments.
Ten expert listeners evaluated the pressedness and the breathiness of one sentence recorded before and after each loading session....
La charge vocale : De sa quantification à l’étude de son impact sur la fonction phonatoire et sur la qualité vocale - Remacle, Angélique
Ce travail étudie la charge vocale principalement chez les enseignants. La prévalence élevée des troubles de la voix chez ces professionnels serait en partie liée aux trois facteurs principaux de charge vocale que sont la durée de phonation, le niveau de pression sonore, et la fréquence vocale. Ces facteurs sont associés à des contraintes mécaniques appliquées aux plis vocaux lors de la vibration, potentiellement responsables de microtraumatismes du tissu, et participant au développement de lésions bénignes.
Notre contribution intervient à deux niveaux d’étude de la charge vocale. Dans un premier temps, nous l’avons quantifiée en situation écologique dans une population d’enseignantes,...
Vocal loading profiles of kindergarten and elementary school teachers - Remacle, Angélique; Morsomme, Dominique; FINCK, Camille
Purpose: Although a global picture exists of teachers’ voice demands in general, few studies have compared specific groups of teachers to determine whether some are more at risk than others to develop vocal loading related dysphonia. This study compared vocal loading of kindergarten and elementary school teachers; professional and non-professional vocal load was determined for both groups.
Method: Twelve kindergarten and twenty elementary school female teachers were monitored during one workweek using the Ambulatory Phonation Monitor, Model 3200 (KayPENTAX). Vocal loading parameters analyzed were phonation time, F0, SPL, distance dose and cycle dose. A total of 160 days (≈1513 hours) of...
Novel cooperation between CX3CL1 and CCL26 inducing NK cell chemotaxis via CX3CR1: a possible mechanism for NK cell infiltration of the allergic nasal tissue. - EL SHAZLY, Amr; Castillo- Doloriert, Hugo; Bisig, Bettina; Lefèbvre, Philippe; Delvenne, Philippe; Jacobs, Nathalie
BACKGROUND: Recent data indicated that natural killer (NK) cells and chemokines could play a pivotal role in nasal inflammation. CX3CR1, the only receptor for fractalkine/CX3CL1, is abundantly expressed by NK cells, and was recently shown to also be a receptor for eotaxin-3/CCL26. However, no reports explored the NK cells-CX3CL1-CCL26 axis via CX3CR1 in allergy. OBJECTIVE: Our goals were first to determine specifically NK cell recruitment pattern in nasal tissue of allergic chronic rhinosinusitis (ACRS) and non-allergic chronic rhinosinusitis (NACRS) patients in comparison with healthy controls, and secondly, to investigate the function of CX3CR1 in NK cell migration. METHODS: Immunohistochemistry, microchemotaxis...
