Endoscope-assisted microsurgery for tumors of the septum pellucidum: surgical considerations and benefits of the method in the treatment of four seri…
2003
Neoplasms that primarily originate from the septum pellucidum are extremely rare. Generally the septum pellucidum is involved in direct extension of tumors that arise from the neighboring structures, principally the corpus callosum. Endoscope-assisted techniques form a useful adjunct to common microsurgical procedures to completely remove intraventricular lesions. There are two main advantages of endoscope-assisted surgery over common microsurgical techniques: reduction of superficial brain retraction with less iatrogenic trauma to the neighboring structures and inspection of hidden corners depict simultaneously anatomical details which are not precisely visible in the zoomed and thus light…
The influence of university students stress mindsets on health and performance outcomes
2018
Background Emerging evidence indicates that holding particular stress mindsets has favorable implications for peoples’ health and performance under stress. Purpose The aim of the current study was to examine the processes by which implicit and explicit stress mindsets relate to health- and performance-related outcomes. Specifically, we propose a stress beliefs model in which somatic responses to stress and coping behaviors mediate the effect of stress mindsets on outcomes. Methods Undergraduate university students (N = 218, n = 144 females) aged 17– 25 years completed measures of stress mindset, physical and psychological wellbeing, perceived stress, perceived somatic responses to stress, p…
Normal reference values of multilayer longitudinal strain according to age decades in a healthy population: A single-centre experience.
2017
Aims Recent advancements in echocardiographic technology allow to analyse myocardial strain in multiple layers. Little is known about the impact of age on layer-specific longitudinal strain in healthy subjects. The aim of this study was to analyse the influence of age on multilayer longitudinal strain and establish normal reference values of layer-specific strain according to age decades in a healthy population referring to our echo laboratory using 2D speckle-tracking echocardiography with layer-specific software. Methods and results Two-hundred sixty-six healthy, consecutive subjects (mean age = 39.2 ± 17.5 years, women/men = 137/129), free of cardiovascular risk factors, were enrolled. S…
Subepithelial connective tissue graft with or without enamel matrix derivative for the treatment of Miller class I and II gingival recessions: a cont…
2012
Background The aim of this study was to evaluate whether the combination of enamel matrix derivative (EMD) with subepithelial connective tissue graft (SCTG) plus coronally advanced flap (CAF) would improve the treatment outcomes of Miller class I and II gingival recessions when compared with the same technique (SCTG plus CAF) alone. Methods The study was designed as a randomized, parallel, controlled, double-blinded clinical trial. Forty-two patients were randomly assigned in the test group (SCTG plus EMD) and in the control group (SCTG). Patients had at least one gingival recession ≥ 2 mm. The clinical parameters were evaluated at baseline and at 14 d, 1, 3, 6 and 12 mo follow-up time poin…
The aged brain: Genesis and fate of residual progenitor cells in the subventricular zone
2015
Neural stem cells (NSCs) persist in the adult mammalian brain through life. The subventricular zone (SVZ) is the largest source of stem cells in the nervous system, and continuously generates new neuronal and glial cells involved in brain regeneration. During aging, the germinal potential of the SVZ suffers a widespread decline, but the causes of this turn down are not fully understood. This review provides a compilation of the current knowledge about the age-related changes in the NSC population, as well as the fate of the newly generated cells in the aged brain. It is known that the neurogenic capacity is clearly disrupted during aging, while the production of oligodendroglial cells is no…
Telomere Shortening in Neural Stem Cells Disrupts Neuronal Differentiation and Neuritogenesis
2009
Proliferation in the subependymal zone (SEZ) and neurogenesis in the olfactory bulb decline in the forebrain of telomerase-deficient mice. The present work reveals additional effects of telomere shortening on neuronal differentiation, as adult multipotent progenitors with critically short telomeres yield reduced numbers of neurons that, furthermore, exhibit underdeveloped neuritic arbors. Genetic data indicate that the tumor suppressor protein p53 not only mediates the adverse effects of telomere attrition on proliferation and self-renewal but it is also involved in preventing normal neuronal differentiation of adult progenitors with dysfunctional telomeres. Interestingly, progenitor cells …
Changes in sprint performance and sagittal plane kinematics after heavy resisted sprint training in professional soccer players
2019
Background Sprint performance is an essential skill to target within soccer, which can be likely achieved with a variety of methods, including different on-field training options. One such method could be heavy resisted sprint training. However, the effects of such overload on sprint performance and the related kinetic changes are unknown in a professional setting. Another unknown factor is whether violating kinematic specificity via heavy resistance will lead to changes in unloaded sprinting kinematics. We investigated whether heavy resisted sled training (HS) affects sprint performance, kinetics, sagittal plane kinematics, and spatiotemporal parameters in professional male soccer players.…
Portrait des jeunes NEET sur vingt ans : le cas des diplômé.e.s de CAP-BEP
2021
International audience; Le nombre de jeunes NEET (Not in Education, Employment or Training) est estimé en France à près de 2 millions, représentant 17 % des 15 à 29 ans. Cette population composite sur le plan du capital scolaire regroupe des jeunes qui ne sont pas exposés de manière identique aux aléas économiques et/ou qui n’ont pas les mêmes attentes vis-à-vis de l’emploi. Ce chapitre dévoile les difficultés rencontrées sur le marché du travail qui peuvent se cumuler et enfermer les jeunes diplômé·e·s de l’enseignement professionnel court dans une spirale de vulnérabilité, à travers quatre enquêtes du Céreq qui retracent leurs parcours. Pour quelles raisons ces diplômé·e·s de CAP-BEP (pre…

CAP et BEP : une insertion typée selon la spécialité
1995
International audience; Toutes les études consacrées à l'insertion s'accordent à reconna\ⁱtre que les itinéraires des jeunes sont de plus en plus longs et complexes, où alternent périodes de chômage, d'emplois précaires, de stages .. Le risque de chômage s'avère d'autant plus grand que le niveau de formation est faible, l'écart entre sexes est nettement en défaveur des jeunes filles en ce qui concerne l'accès à l'emploi. La dégradation générale du marché du travail a profondément retenti sur la situation des débutants à leur entrée dans la vie active. Pourtant cette détérioration générale renforce les disparités d'insertion selon le niveau de formation, la spécialité suivie et la région de …
