Relatório de estágio - Mestrado em Ensino da MúsicaRésumé-Section I - En septembre 2012, l’auteur a été engagé comme professeur au Conservatoire à Rayonnement Départemental du Choletais en France et a pris la classe de cor constituée de 25 élèves en charge. Dans un premier temps, l’auteur présente le projet pédagogique établi pour cette classe. Il répond aux exigences liées à son cadre d’emploi et tient compte des con naissances académiques acquises lors de sa formation à l’École Supérieure de Musique de Lisbonne et à l’École Supérieure d’Éducation. Dans un second temps, lors d’une description et d’une analyse de la mise en place de ce projet pédagogique pour l’ensemble de la classe, il aborde les sujets de l’enseignement adapté aux élèves déficients, l’enseignement aux adultes et de la transversalité des enseignements. Finalement est analysé, sur la base de ce projet pédagogique, le cas d'un élève de chaque cycle d'enseignement classique.Résumé-Section II - Depuis l’abaissement de l’âge d’entrée en 1er cycle dans l’enseignement spécialisé de la musique décrété par le ministère de la Culture dans les schémas d’orientation pédagogique des 20 dernières années, les cors standards doubles utilisés jusqu’à présent représentent de par leur poids un obstacle à l’apprentissage. En 1981, suite à une formation de 3 ans comme thérapeute de technique Alexander, le corniste anglais Pip Eastop conçoit un pied-support qui lui permet de jouer du cor tout en respectant "le bon usage de soi". Cette étude se concentre sur ce pied-support et cherche à définir s’il est possible de le considérer comme un outil ergonomiquement valide pour l’acquisition des compétences fondamentales présentées en 1ère section. Sont présentés un historique de l'évolution du poids du cor, les solutions envisageables pour l'enseignement du cor, une étude empirique basée sur des questionnaires effectuée au sein de la classe de cor du Conservatoire à Rayonnement départemental du Choletais et pour conclure est abordée en discussion finale les conséquences de l'ergonomie sur l'enseignement spécialisé de la musique.Abstract-Section I - In September 2012, the author was taken on as a French horn teacher at the "Conservatoire à Rayonnement Départemental du Choletais" in France, taking over the corresponding class of 25 students. Firstly, the author presents the educational project designed specifically for this class. It meets the requirements of his job description, and reflects the academic knowledge acquired during his training at the "Escola Superior de Musica de Lisboa," as well as at the "Escola Superior da Educacao." Secondly, by describing and analysing the implementation of this educational project for the whole class, the author examines issues regarding the education of "special-needs" students, adult education and the transversatily of musical teaching syllabuses. Finally, based on the educational project, the author analyses the individual case of a student from each of the classical cycle.Abstract Section II - Since the lowering of the age of entry to the first cycle in special, musical education in a decree enacted over the past twenty years by the Ministry of Culture, the double- standard French horns used so far have been a barrier to learning, simply through their sheer weight. In 1981, after three years training as a therapist using the "Alexander Method," the English French horn player, Pip Eastop, designed a hornstick which enabled him to play while maintaining "the proper use of the self." This study focuses on the hornstick, and attempts to ascertain whether it is possible for the hornstick to be considered as an ergonomically-valid tool for the acquisition of the basic skills presented in the first section. The author presents the history of the evolution of the weight of the French horn, some possible solutions for teaching the French horn, as well as an empirical study based on questionnaires completed by members of the French horn classes at the "Conservatoire à Rayonnement Département du Choletais," before concluding by examining the ergonomic consequences on teaching methods.N/

Brain monoaminergic neurons and ventilatory control in vertebrates

Monoamines (noradrenaline (NA), adrenaline (AD), dopamine (DA) and serotonin (5-HT) are key neurotransmitters that are implicated in multiple physiological and pathological brain mechanisms, including control of respiration. The monoaminergic system is known to be widely distributed in the animal kingdom, which indicates a considerable degree of phylogenetic conservation of this system amongst vertebrates. Substantial progress has been made in uncovering the participation of the brain monoamines in the breathing regulation of mammals, since they are involved in the maturation of the respiratory network as well as in the modulation of its intrinsic and synaptic properties. On the other hand, for the non-mammalian vertebrates, most of the knowledge of central monoaminergic modulation in respiratory control, which is actually very little, has emerged from studies using anuran amphibians. This article reviews the available data on the role of brain monoaminergic systems in the control of ventilation in terrestrial vertebrates. Emphasis is given to the comparative aspects of the brain noradrenergic, adrenergic, dopaminergic and serotonergic neuronal groups in breathing regulation, after first briefly considering the distribution of monoaminergic neurons in the vertebrate brain.

Molecular hydrogen downregulates acute exhaustive exercise-induced skeletal muscle damage

Physical exercise-induced skeletal muscle damage may be characterized by increased oxidative stress, inflammation, and apoptosis which may be beneficial when exercise is regular, but it is rather harmful when exercise is exhaustive and performed acutely by unaccustomed individuals. Molecular hydrogen (H2) has emerged as a potent antioxidant, anti-inflammatory, and anti-apoptotic agent, but its action on the deleterious effects of acute exhaustive exercise in muscle damage remain unknown. Therefore, we tested the hypothesis that H2 decreases acute exhaustive exercise-induced skeletal muscle damage of sedentary rats. Rats ran to exhaustion on a sealed treadmill inhaling an H2-containing mixture or the control gas. We measured oxidative stress (SOD, GSH, and TBARS), inflammatory (TNF-α, IL-1β, IL-6, IL-10, and NF-kB phosphorylation) and apoptotic (expression of caspase-3, Bcl-2, and HSP70) markers. Exercise caused no changes in SOD activity but increased TBARS levels. H2 caused increases in exercise-induced SOD activity and blunted exercise-induced increased TBARS levels. We observed exercise-induced TNF-α and IL-6 surges as well as NF-kB phosphorylation, which were blunted by H2. Exercise increased cleaved caspase-3 expression, and H2 reduced this response. In conclusion, H2 effectively downregulates muscle damage, reducing oxidative stress, inflammation, and apoptosis after acute exhaustive exercise performed by an unaccustomed organism.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Involvement of endogenous central hydrogen sulfide (H2S) in hypoxia-induced hypothermia in spontaneously hypertensive rats

Spontaneously hypertensive rats (SHR) display autonomic imbalance and abnormal body temperature (Tb) adjustments. Hydrogen sulfide (H2S) modulates hypoxia-induced hypothermia but its role in SHR thermoregulation is unknown. We tested the hypothesis that SHR display peculiar thermoregulatory response to hypoxia, and that endogenous H2S overproduced in the caudal nucleus of the solitary tract (NTS) of SHR modulates this response. SHR and Wistar rats were microinjected into the fourth ventricle with aminooxyacetate (AOA, H2S-synthesing enzyme inhibitor) or sodium sulfide (Na2S, H2S donor) and exposed to normoxia (21% inspired O2) or hypoxia (10% inspired O2, 30 min). Tb was continuously measured, and H2S production rate was assessed in caudal NTS homogenates. In both groups, AOA, Na2S or vehicle (saline, 1 ÂľL) did not affect euthermia. Hypoxia caused similar decreases in Tb in both groups. AOA presented a longer latency to potentiate hypoxic hypothermia in SHR. Caudal NTS H2S production rate was higher in SHR. We suggest that increased bioavailability of H2S in the caudal NTS of SHR enables the adequate modulation of excitability of peripheral chemoreceptors-activated NTS neurons that ultimately induce suppression of brown adipose tissue thermogenesis thus accounting for the normal hypoxic hypothermia.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Relationship between resting heart rate and anthropometric, metabolic and hemodynamic parameters in the elderly aged 80 years and over

Abstract This study examined the relationship between resting heart rate (RHRr) and anthropometric, metabolic and hemodynamic parameters in subjects aged 80 years and over. One hundred thirteen individuals were divided into two groups (RHR:<66 beats/min and ≥66 beats/min). Anthropometric parameters (weight, height, body mass index and waist circumference (WC) were measured. Hemodynamic parameters (systolic (SBP) and diastolic (DBP) pressure) were measured and pulse pressures (PP) were obtained. Metabolic parameters were fasting blood glucose, triglycerides and total cholesterol. In elderly aged 80 and over, RHR influenced the changes observed in DBP, PP and triglycerides. Additionally, subjects with RHR≥66 beats/min had higher DBP, glucose, total cholesterol and lower PP as compared with elderly with RHR<66 beats/min. Men demonstrated greater weight, height, and WC than women while women had higher percentage of body fat, trunk fat, and higher total cholesterol. Thus, subjects with 80 years old and over who present RHR≥66 have higher DBP and lower PP and heart rate variability compared with the elderly with RHR<66
