Full textThis work is a critical reappraisal of the catechesis conceived and practiced during more than five centuries among the Kongo people, considered here as a vast cultural and linguistic zone. The principal problematic of this research takes its origin from an observation in the ancient and contemporary history of evangelization in Africa : three encounters between Christianity and African cultural traditions, at three differents periods that have all ended up in a deadlock. One can ask the following question : "How can the Christian proposition in the catechesis be really pertinent, in other that it may be received and welcomed as the message of salvation ?"

Full textLe vieillissement est un concept complexe. De nombreuses théories ont été proposées dans le but d’expliquer le processus du vieillissement. La théorie mitochondriale du vieillissement est devenue l’une des théories les plus testées et les plus connues dans la recherche sur le vieillissement. Sa principale conclusion est que le vieillissement résulte de l’accumulation de dommages oxydatifs qui sont étroitement liés à la libération d’espèces réactives de l’oxygène (ROS) des mitochondries. Le vieillissement musculaire est habituellement associé à une diminution de la masse, de la force et de la vitesse de contraction. L’un des effets les plus marquants du vieillissement sur les muscles est la sarcopénie (sarco = chair et pénie = perte). Il a été suggéré que la sarcopénie peut être déclenchée par les ROS qui se sont accumulées tout au long de la vie. Le mode de vie sédentaire et la malnutrition représentent des facteurs de risques majeurs pour ce syndrome. Bien qu’il n’existait pas de définition opérationnelle universellement acceptable, les chercheurs conviennent que l’incidence de la sarcopénie augmente avec l’âge adulte avancé. Ainsi, comprendre la sarcopénie et développer des interventions thérapeutiques et de réadaptation pour ralentir ses progrès ou inverser partiellement ses effets est un enjeu scientifique très important. Dans ce contexte, notre équipe a identifié les gènes modulés dans le muscle squelettique après un exercice d’endurance chez les personnes âgées et a mis en évidence l’importance du remodelage de la matrice extracellulaire (MEC) et de la fonction mitochondriale dans l’adaptation du muscle squelettique en utilisant une technique de génomique fonctionnelle. L’un des gènes induit par l’exercice d’endurance code pour une protéine sécrétée acide et riche en cystéine (SPARC), qui contrôle le remodelage de la MEC et joue un rôle clé dans la différenciation des myoblastes. Le travail présenté dans cette thèse consiste à analyser les données bibliographiques indiquant l’importance de la génomique fonctionnelle dans la compréhension de la sarcopénie et à démontrer les rôles de SPARC dans le lien possible entre le remodelage de la MEC et la fonction mitochondriale. Le premier objectif de cette thèse était de décrire les stratégies de génomique fonctionnelle, principalement les techniques de l’expression différentielle : puces à ADN, analyse en série de l’expression des gènes (SAGE), L'ordonnancement parallèle massif de signature (MPSS), séquençage de l’ARN (RNAseq), l’analyse différentielle représentationnelle (RDA) et l’hybridation suppressive soustractive (SSH). De plus, nous avons démontré l’importance de ces techniques pour découvrir de nouvelles cibles thérapeutiques pour certaines maladies complexes ainsi que l’application de ces outils pour étudier la modulation du transcriptome du muscle squelettique. Notre deuxième objectif était de démontrer l’implication de différentes techniques de génomique fonctionnelle telles que l’interférence ARN, protéomique, souris transgéniques, métabolomique, génomique et épigénomique dans la compréhension de la sarcopénie. De plus, nous avons signalé la progression des nouvelles découvertes et des nouvelles applications de ces méthodes dans le domaine de la sarcopénie. Notre troisième objectif était de montrer l’implication de SPARC dans la modulation de la MEC et de la fonction mitochondriale des cellules musculaires murines C2C12. Nous avons étudié l’effet exogène de l’inhibition ou l’induction de SPARC sur la différenciation des cellules C2C12, l’expression des protéines structurelles de la MEC et les protéines mitochondriales durant la prolifération, la différenciation et après la formation des myotubes. Nos résultats indiquent que SPARC joue un rôle crucial dans la différenciation des cellules musculaires, dans le remodelage de la MEC, et pourrait être impliquée dans le lien possible entre la MEC et la fonction mitochondriale. Finalement, nous avons étudié le mécanisme par lequel SPARC pourrait moduler la MEC et la fonction mitochondriale dans les cellules musculaires et nous avons utilisé la technique de la stimulation électrique, in vitro, qui a révélé une induction remarquable de l’expression génique de Sparc. Les résultats de cette étude nous ont permis de démontrer que SPARC joue un rôle important dans le remodelage du MEC ainsi que dans la modulation de la fonction mitochondriale des cellules musculaires. Le lien possible entre la MEC et la mitochondrie pourrait constituer une cible thérapeutique prometteuse pour le traitement des maladies ou les syndromes liés à un dysfonctionnement de la MEC/mitochondrie. Enfin, on croit aussi que cette voie ouvrira les portes à de nouvelles découvertes dans le domaine de la sarcopénie.
The definition of aging is complicated by the appearance of various diseases that alter body functions and tissue structures. Many theories have been proposed to explain the process of aging. The mitochondrial theory of aging has become one of the most tested and well-known theories in aging research. Its main conclusion is that aging results from the accumulation of oxidative damage which is closely related to the release of reactive oxygen species (ROS). On the other hand, aging in the muscle is usually associated with a decrease in mass, strength, and rate of contraction. One of the most striking effects of aging on muscles is sarcopenia, (sarco = flesh and penia = loss). It has been suggested that sarcopenia can be triggered by ROS which are accumulated over a lifetime. Sedentary lifestyle and malnutrition represent major risk factors for this syndrome. Although there is no operational definition which is universally acceptable, researchers agree that the incidence of sarcopenia increases with advancing adulthood. Thus, understanding sarcopenia and developing therapeutic and rehabilitative interventions to slow its progress or partially reverse its effects is a very important scientific issue In this context, our team identified modulated genes in skeletal muscle after endurance exercise in the elderly and highlighted the importance of extracellular matrix remodeling (ECM) and mitochondrial function using a functional genomic technique. One of the genes induced by endurance exercise codes for a secreted acid-rich cysteine protein (SPARC), which controls the remodeling of the ECM and plays a key role in the differentiation of myoblasts. The work presented in this thesis consists of analyzing bibliographic data indicating the importance of functional genomics in understanding sarcopenia and to demonstrate the roles of SPARC in the possible link between ECM remodeling and mitochondrial function. The first objective of this thesis was to describe functional genomic strategies, mainly the techniques of differential expression: DNA chips, serial analysis of gene expression (SAGE), massively parallel signature sequencing (MPSS), RNA sequencing (RNAseq), representational differential analysis (RDA), and subtractive suppression hybridization (SSH). In addition, we have demonstrated the importance of these techniques to discover new therapeutic targets for certain complex diseases as well as the application of these tools to study the modulation of the skeletal muscle transcriptome. Our second objective was to demonstrate the involvement of different functional genomic techniques such as RNA interference, proteomics, transgenic mice, metabolomics, genomics and epigenomics in the understanding of sarcopenia. In addition, we have reported the progress of new discoveries and applications of these methods in the field of sarcopenia Our third objective was to show the involvement of SPARC in the modulation of ECM and the mitochondrial function of C2C12 murine muscle cells. We investigated the exogenous effect of SPARC (inhibition and or induction) on C2C12 cell differentiation, expression of ECM structural proteins, and mitochondrial proteins during proliferation, differentiation, and after the formation of myotubes. Our results indicate that SPARC plays a crucial role in muscle cell differentiation, remodeling of ECM and may be involved in the possible link between ECM and mitochondrial function. Finally, we investigated the mechanism by which SPARC could modulate ECM and mitochondrial in muscle cells and we used the technique of electrical stimulation, in vitro, which revealed a remarkable induction of Sparc gene expression. The results of this study allowed us to demonstrate that SPARC plays an important role in the remodeling of ECM as well as in modulating the mitochondrial function of muscle cells. The possible link between ECM and mitochondria may be a promising therapeutic target for the treatment of ECM/mitochondria dysfunction-related diseases. It is also believed that this pathway will open the doors to new discoveries in the field of sarcopenia.

Full textIn mammal, the DNA of interphasic cells is organized into the chromatin fiber which is itself confined inside “chromosome territories”. This compact organization allows the establishment of long-range interactions involved in the fine regulation of genomic processes. However, the organization and the dynamic of the chromatin at the so-called supranucleosomal scale (10 to 500kb) remain unclear. In order to study the chromatin at this scale, we used the 3C-qPCR method that allows to measure interaction frequencies between two genomic regions. Firstly, we have analyzed random collisions in order to determine the intrinsic organization of the chromatin at the supranucleosomal scale. Our data indicates that, in the absence of specific interactions, random collisions in gene-rich regions show a periodic modulation of about 90kb. This modulation seems to be underlying numerous locus-specific interactions and have repercussions on their genomic location, thus contributing to genome evolution. Models, derived from polymers physics, suggest that, in these regions, the chromatin is shaped in a statistical helix. Secondly, we have investigated the tridimensional organization of the Igf2/H19 mouse locus which is subject to genomic imprinting. Specific interactions identified between endodermic enhancers and some regions of the locus have confirmed the existence of a hierarchy of interactions and allowed the discovery of a new imprinted locus (PIHit). This locus produces a non-coding RNA that we have characterized but for which the function remains to be determined.Finally, my work also led to the development of a new technology (HRS-SEQ) that allows to study global genome organization through mapping of high-salt recovered sequences (HRS)

Full textIn the automobile field, large scale implementation of embedded stereovision systems is facing a particular challenge. Matching algorithms usually require a perfectly aligned camera set, which is difficult to achieve. In this thesis, we consider software solutions in order to overcome this constraint, thus we can use very roughly aligned cameras. The idea is to rectify images, in order to produce fast sparse 3d maps. Automatic estimation of the epipolar geometry using only image data is being reviewed, and we conclude on it's reliability, assuming that an adequate scene is provided. A reliability score computing scheme is proposed, based on correlation between several criterions and the correctness of the geometry estimation. This technique is experimentally validated, and it will be used to determine if the estimated geometry should be used or not to rectify images. Image rectification techniques are also reviewed, and the implementation details are given. A criterion is used to find the rectification that minimizes image distorsion. A solution is given in order to determine horizontal relative situation of both images, so depth error is minimised in case of direct depth extraction. For the production of sparse depth maps, fast extraction of features and matching topics are covered. For feature extraction, minor improvements are suggested. For matching, a new algorithm is proposed, that improves both speed and matches ratio. Finally, several architectures are considered for depth map production, through direct depth extraction or 3D reconstruction
Bugarin, Florian. "Vision 3D multi-images : contribution à l’obtention de solutions globales par optimisation polynomiale et théorie des moments." Thesis, Toulouse, INPT, 2012. http://www.theses.fr/2012INPT0068/document.
Full textThe overall objective of this thesis is to apply a polynomial optimization method, based on moments theory, on some vision problems. These problems are often nonconvex and they are classically solved using local optimization methods. Without additional hypothesis, these techniques don’t converge to the global minimum and need to provide an initial estimate close to the exact solution. Global optimization methods overcome this drawback. Moreover, the polynomial optimization based on moments theory could take into account particular constraints. In this thesis, we extend this method to the problems of minimizing a sum of many rational functions. In addition, under particular assumptions of "sparsity", we show that it is possible to deal with a large number of variables while maintaining reasonable computation times. Finally, we apply these methods to particular computer vision problems: minimization of projective distortions due to image rectification process, Fundamental matrix estimation, and multi-view 3D reconstruction with and without radial distortions
