Bcl-2 expression in thalamus, brainstem, cerebellum and visual cortex of adult primate
No full textDue to the functional importance of Bcl-2, which acts as an anti-apoptotic protein that also affects neural differentiation and adult neurogenesis, we undertook a detailed immunohistochemical study of the distribution of this protein in the brain of squirrel monkeys. The present study describes findings obtained at thalamic, brainstem, cerebellum and visual cortex levels, and the data are compared with our previous results gathered in the same species. At thalamic level, Bcl-2-positive neurons occur in anterior, rostral intralaminar, midline and lateral habenular nuclei. The protein is also expressed in several structures associated with the ventricular system, including the subventricular zone (SVZ), the subcommissural organ, and the periventricular grey at rostral and caudal tips of the fourth ventricle. At brainstem and cerebellar levels, Bcl-2-positive neurons occur in the dorsal raphe nucleus, inferior olivary complex, and in molecular and granular layers of the cerebellum. Finally, neurons of layer IV of the striate cortex display a very strong Bcl-2 immunoreactivity that contrasts with the poor labeling of neurons in adjacent parastriate and peristriate cortices. These finding suggests that Bcl-2 plays a role in the plasticity and structural maintenance of various structures in the primate brain and indicate that the mitotically active SVZ might be more extended along the rostrocaudal axis in primates than in rodents

Le problème de Coulomb-Dunkl dans le plan
No full textCe mémoire, composé d'un article en collaboration avec Monsieur Luc Vinet et
Vincent X. Genest, est la suite du travail effectué sur les systèmes quantiques
super-intégrables définis par des Hamiltoniens de type Dunkl. Plus particulièrement,
ce mémoire vise l'analyse du problème de Coulomb-Dunkl dans le plan qui
est une généralisation du système quantique de l'atome d'hydrogène impliquant des
opérateurs de réflexion sur les variables x et y.
Le modèle est défini par un potentiel en 1/r. Nous avons tout d'abord remarqué
que l'Hamiltonien est séparable en coordonnées polaires et que les fonctions d'onde
s'écrivent en termes de produits de polynômes de Laguerre généralisés et des harmoniques de Dunkl sur le cercle. L'algèbre générée par les opérateurs de symétrie
nous a également permis de confirmer le caractère maximalement super-intégrable
du problème de Coulomb-Dunkl. Nous avons aussi pu écrire explicitement les représentations de cette même algèbre. Nous avons finalement trouvé le spectre de
l'énergie de manière algébrique.This master's thesis, composed of an article in collaboration with Luc Vinet
and Vincent X. Genest, is the result of a work done on superintegrable quantum
systems defined by Hamiltonians of the Dunkl kind. More specifically, the aim
of this paper is to analyse the Coulomb-Dunkl problem in the plane which is a
generalization of the quantum system of hydrogen involving operators of reflection
on the variables x and y.
The model is defined by a potential in 1/r. First, we notice that the Hamiltonian
is separable in polar coordinates and the wave functions are written in terms of
products of generalized Laguerre polynomials and Dunkl harmonics on the circle.
The algebra generated by the symmetry operators has also allowed us to confirm
the maximally superintegrable character of the Coulomb-Dunkl problem. We also
write explicitly the representations of the same algebra. We finally found the energy
spectrum algebraically
Expression pattern of voltage-dependent calcium channel subunits in hippocampal inhibitory neurons in mice
No full textDifferent subtypes of voltage-dependent calcium channels (VDCCs) generate various types of calcium currents that play important role in neurotransmitter release, membrane excitability, calcium transients and gene expression. Well-established differences in the physiological properties and variable sensitivity of hippocampal GABAergic inhibitory neurons to excitotoxic insults suggest that the calcium homeostasis, thus VDCC subunits expression pattern is likely different in subclasses of inhibitory cells. Using double-immunohistochemistry, here we report that in mice: 1) Cav2.1 and Cav3.1 subunits are expressed in almost all inhibitory neurons; 2) subunits responsible for the L-type calcium current (Cav1.2 and Cav1.3) are infrequently co-localized with calretinin inhibitory cell marker while Cav1.3 subunit, at least in part, tends to compensate for the low expression of Cav1.2 subunit in parvalbumin-, metabotropic glutamate receptor 1alpha- and somatostatin-immunopositive inhibitory neurons; 3) Cav2.2 subunit is expressed in the majority of inhibitory neurons except in calbindin-reactive inhibitory cells; 4) Cav2.3 subunit is expressed in the vast majority of the inhibitory cells except in parvalbumin- and calretinin-immunoreactive neurons where the proportion of expression of this subunit is considerably lower. These data indicate that VDCC subunits are differentially expressed in hippocampal GABAergic interneurons, which could explain the diversity in their electrophysiological properties, the existence of synaptic plasticity in certain inhibitory neurons and their vulnerability to stressful stimuli

Characterization and modelling of the PEKK thermomechanical and creep behavior above the glass transition temperature
No full textThe present work focuses on the characterization and the modelling of the PEKK 7002 thermomechanical behavior at temperatures between the glass transition temperature, Tg (≈160 °C), and 200 °C, as experienced in tensile, load-unload-reload and creep-recovery tests. A novel strain measurement image analysis based tool (IAT) is presented and compared with existing measurement setup, and employed for the validation of the strain measurement acquired during the thermomechanical tests. The crystallization kinetics between 165 °C and 200 °C is described and the coupling with thermomechanical solicitations is investigated. An analytical description of the identified mechanisms is proposed for the tensile, load – unload and creep-recovery solicitations and it constitutes a 1-D model of PEKK 7002, which is employed for understanding the experimental results
Assessment and simulation of the thermomechanical tensile and creep behavior of C/PEKK composites for aircraft applications above the glass transition temperature
No full textThe present work focuses on the assessment and the simulation of the thermomechanical tensile and creep behavior of Poly Ether Ketone Ketone 7002/carbon fibers composites behavior under tensile and creep solicitation between the glass transition temperature and 200 °C, via a multiscale approach starting from the behavior of the PEKK 7002 neat polymer. Tensile and creep polymer and composite experimental curves are employed to develop and validate generalized Semi – Analytical Homogenization / Localization Method for the simulation of the thermomechanical tensile and creep behavior of composite laminates. Through the employment of the model, a similarity of behavior between polymer and composites is demonstrated. The proposed algorithm capabilities of simulating the thermomechanical tensile and creep behavior of composites with different ply orientations and stacking sequences are then presented
