Повний текст джерелаThe aim of this work was to determine the optimum of an original carotenoid, the torularhodin, produced by Sporobolomyces ruberrimus, in batch culture. A very interesting characteristic of this strain is its ability to consume raw glycerol as a carbon and energy source for microbial growth and carotenoid production. In the fist part of this study, the identification of operating parameters that have an influence on the optimum torularhodin production, was achieved. Experimental assays reinforced by a statistical study allowed to identify temperature, dissolved oxygen pressure and oleic acid supplementation, as the major parameters of influence, and then the integration of these data was performed for the construction of a multiobjective optimization based on a multicriteria experimental design. The establishment of a mathematical model of a second degree polynomial type was developed for the prediction of the values of µmax and of the torularhodin concentration reported to biomass. In the last part, considering that torularhodin has an important antioxidant property and it exhibits a free carboxyl acid function which can be used as acyl agent, a study of its structure modifying by an enzymatic way as a stabilization pattern was started. The experimental conditions of lysine acylation by the lipase B of Candida antarctica were determined using a model carotenoid, the bixin. The resulting product of the synthesis of bixin derivative was purified and showed an antiradical activity of 2.5 times higher than that of bixin. This result showed the ability of the acylation reaction of peptides with this kind of carotenoids

Повний текст джерелаThe purpose of this work was to investigate the effect of FGF 2 and TGF-β1 on the early steps of dentin regeneration using microencapsulation of theses factors into a microparticles matrix to ensure growth factors protection and to provide bioactive sustained release in contact with dental pulp cells and then the application of the obtained microparticles in direct pulp capping using a culture model of entire tooth. This work involves the optimization of technical means used to achieve encapsulation of TGFβ1, FGF-2 using the poly (lactic-glycolic acid) PLGA. Physicochemical and colloidal characterization of microspheres shows that the microparticles retain their physicochemical characteristics after drying and re-suspended in water. The double emulsion method was used to separately encapsulate (FGF-2) and (TGFβ1). Microparticles morphology, loading, shelf life, potential toxicity and release kinetics were studied. Then the proliferation of dental pulp cells was examined in contact with microparticles. Biological studies show no toxic effect of particles on pulp fibroblasts. Growth factors have kept their specific biological activity. A culture model of human entire tooth was used to achieve the application of microparticles as a dental direct capping material to confirm their biological activities ex vivo. These microparticles can be useful in studies of early steps of dentin regeneration, activation and migration of progenitor cells in dental pulp

Повний текст джерелаIt is necessary to understand the behavior of structures up to their failure to enhance their design. The mechanisms and phenomena undergoing failure vary according to the considered material and boundary conditions. We consider homogeneous materials for which cracks propagate in a context where behavior nonlinearities are not dominants. These conditions are matched for brittle and quasi-brittle materials and for some fatigue cracks. For the former, the main source of dissipation is the crack propagation which can be seen as the generation of a new free-surface. For the later, there is many applications where, in one loading cycle, the nonlinearities remains confined around the crack tip. The linear elastic fracture mechanics theory is then a pertinent model to approximate the structure behavior. Under such hypotheses, a singularity appears in the crack tip vicinity. The Williams' series expansion is computed from the asymptotic study of plane and anti-plane states. The stress is singular at the crack tip and the order of this singularity is one out of two. The singularity amplitude is quantified by the stress intensity factors (SIF), one for each of the three loading modes. In 3D, the crack shape is potentially complex (front curvature and non-planar crack), and no general asymptotic series expansion exists. In this PhD thesis, the 2D Williams' series in displacements are used and regularized with a finite element evolution along the front. From this 3D definition of the asymptotic fields in the crack tip vicinity, a numerical method for direct estimation of the SIF (DEK-FEM) is extended to 3D. This method is based on domain decomposition, the two domains are bounded in a weak sense on their interface. In the crack tip vicinity, the mechanical fields are approximated by a truncation of the asymptotic series expansion. Therefore, appropriate fields are used to deal with the singularity, and the associated degrees of freedom are directly the asymptotic coefficients. Among these coefficients are the SIF and the T-stresses. To bridge the scales between the structure and the crack front singularity and to increase the numerical efficiency, this method is embedded in a localized X-FEM multigrids approach. The proposed method is shown to provide an accurate evaluation of the SIF and T-stresses evolution. This approach has been developed in combination of an experimental post-processing method (full field displacement measurement through image correlation) based on the same asymptotic series expansion. The 3D images can be obtained for in situ fatigue experiments by X-ray microtomography and reconstruction. The crack geometry and the SIF are then provided by image correlation and regularization based on Williams series expansion. These data can be used for identifying a 3D fatigue crack growth law. The efficiency of the method is illustrated in 2D

Повний текст джерелаBeer gushing is an explosive over-generation of foam following the opening of a bottle. It is highly dependent on barley growing and harvesting climatic conditions and has been observed more frequently over the past years. Current technics, such as the modified Carlsberg test, only provide informations on a predictive gushing potential of malt with a large uncertainty. A rapid screening test on raw material leading to the identification of actual factor(s) responsible for the gushing is consequently highly required by the brewing industry. But a lack of informations about the compounds involved in gushing limits the development of such a technic. The initial goal of this study was to identify the compounds involved in beer gushing. This approach has been applied to industrial malts presenting gushing potential or not and artificially contaminated barleys in order to set a procedure to isolate compounds which may trigger gushing. In a first time, malt extracts, which are complex mixtures, have been produced and fractionated according to the properties of compounds such as their size, their foaming capacity or hydrophobicity. A good reduction of complexity of sample has been obtained after membrane filtration. Nevertheless, compounds like carbohydrates, proteins and polyphenols could not have been separated. Besides, separation by hydrophobicity has provided good information about the diversity of proteins but the analysis of their gushing potential remains difficult. Afterwards, in order to investigate the production of compounds by fungus at the surface of barley simulating real field crop production conditions, an artificial contamination was achieved and surface extraction with ultrapure water has been performed. Extracted molecules have been screened for their gushing activity. Thus, a purification of molecules by reverse phase chromatography allowed to isolate a gushing fraction from the surface extract. This fraction, which concentrates the gushing properties, is composed by proteins with high hydrophobicity which may be involved in gushing. This fraction was analyzed more in depth with a 2DE, and led to the identification of proteins all produced by fungus family. Among them, a protein called Epl1 appears to be of interest and could be a good candidate thanks its properties closed to hydrophobins (size and hydrophobicity). In conclusion, this methodology is developed to acquire a better knowledge about compounds produced by fungi at the surface of barley as well as to some industrial malt

Повний текст джерелаThe work focuses on methods for predicting the adhesive failure strength of a bonded joint, that is to say the resistance to delamination at an interface between a substrate and the adhesive layer. It attempts to define a method to quickly calculate a criterion for the failure initiation to serve a particular application domain: space construction where assemblies undergo thermal loading at low temperatures, the studied materials being structural adhesive Scotch-Weld DP490, invar and silicon carbide. The conventional criterion of the stress intensity factor has been chosen a priori, its formulation being "K < KC” where K is an indicator of the peeling stress intensity at the end of the interface, and KC is a critical value beyond which the rupture occurs. The main objective being to develop a simple and quick method to calculate K, an approach using influence parameters is proposed. It is based on four reference stresses, three of them being obtained at a well defined point of a specific mesh, from a very few detailed finite element analysis, the fourth being the homogeneous peel stress which appears in the entire singular zone in thermal loading conditions. The identification of the four influence parameters is based on a numerical experiments plan where three different types of loads are considered. The gap between the results obtained and reference values remains low. The proposed method is then applied to various concrete configurations corresponding to tests performed by an industrial partner. It is shown that the calculation of K is reliable, but that, cons, the criterion appears not to be suitable for application area considered here

Повний текст джерелаFor a decade, monoclonal antibodies have become increasingly important for the biotherapeutic management of cancer. However, none of the monoclonal antibodies currently on the market or in late stage clinical trial do target a G-protein coupled receptor in spite of the emerging role of these receptors in tumor progression. Among the therapeutically relevant GPCRs for oncology, the endothelin receptors (ETAR and ETBR) are particularly attractive considering their overexpression in a wide range of tumors and their involvement in various stages of tumorigenesis. In this context, my PhD project consisted in producing and characterizing monoclonal antibodies directed against endothelin receptors with a view to use them as anti-tumor agents. Using an original DNA immunization strategy, we produced a panel of 27 monoclonal antibodies which selectively recognized ETBR expressed at the surface of transfected cells. One of these antibodies, named rendomab-B1, was extensively characterized and proved to be a potent allosteric antagonist of ETBR. Moreover, rendomab-B1 was able to disrupt the autocrine ET1-mediated survival loop on vascular endothelial cells, suggesting that this antibody could be used to prevent the pro-tumorigenic effect due to ET-1 and ETBR upregulation in the tumor-surrounding endothelium. Furthermore, rendomab-B1 binding onto ETBR was also assessed on melanoma cell lines and revealed that a tumor-specific form of ETBR may exist, as illustrated by the poor fixation of rendomab-B1 on these cells in spite of the presence of functional ETB receptors. Together, these results present rendomab-B1 as promising agent, not only for the structural and functional study of ETBR, but also for its therapeutic modulation in the case of cancer for instance. Finally, the other 26 monoclonal antibodies, whose characterization is still ongoing, also constitute potential tools for fundamental or therapeutic applications involving ETBR. To conclude, this work has highlighted the relevance of the DNA immunization approach to generate monoclonal antibodies against the native form of GPCRs

Повний текст джерелаThe life cycle of a satellite includes the launch phase, the positioning on the desiredorbit, different maneuvers (deployment of solar panels and safety position), and finallyplacing the satellite on the junk orbit. The satellite gravitates in a hostile environment,exposed to thermal variations of very large amplitude, alternating sun exposure andeclipse phases. The survival of the satellite depends on the temperature of its components, the variation of which must be monitored within safety intervals. In this context, the thermal simulation of the satellite for its design is crucial to anticipate the reality of its operation. Radiative thermal simulation is essential for anticipating the generation of energy from solar and albedo radiation, and for regulating temperatures of on-board equipments. Ideal operation consists in providing appropriate cooling for components exposed to radiation, and conversely, heating of unexposed components. As an order of magnitude, the external temperature ranges from -150 to +150 degrees Celsius, and the internal electronic equipment has a safe range between -50 and +50, with a safety margin of 10 degrees. In the eclipse phase where the radiation is significantly lower, heating is provided by the energy accumulated during the exposed phase, combined with heat pipes for thermal regulation.In this thesis, the objective is to advance the knowledge on radiative thermal simulation calculation methods for satellites. To this end, two approaches are considered. Thefirst approach consists in establishing a reference calculation of a quantity governing radiative thermal simulation: view factors. Being subject to time constraints, this methodis based on a hierarchical data structure enabling progressive computation of view factors, in order to offer a satisfactory tradeoff between time dedicated to computationsand desired accuracy. For the sake of accuracy, a prediction step is added to guaranteea better convergence towards the reference value.The second approach, also motivated by time constraints, aims at reducing the geometric model of a mechanical part or a spacecraft while being faithful to the numericalsimulation. In order to render the decimation physics-informed, a preprocessing step relying on a sensitivity analysis is carried out. To better preserve the physical simulation,the geometric cost of a simplification operator is coupled to a factor deduced from thesimulation deviation between the reference model and the reduced model

Повний текст джерелаThe general practitioner (GP) is often confronted with patients with mental health problems related to work. The objective of this study is to determine the prevalence of work related mental distress in patients consulting their GP and to study the association between mental distress and psychosocial factors at work. This work is based on the Héraclès study conducted among 2,027 patients in professional activity consulting their GP in the Nord - Pas-de-Calais. Mental distress was evaluated with the MINI International Neuropsychiatric Interview, by the patient's statement and the GP’s diagnosis. The association between mental distress objectified by the MINI and psychosocial factors at work was studied using a Poisson regression or a logistic regression model. The prevalence of work related mental distress objectified by the MINI was 25.6%, 24.5% for mental distress reported by the patient and 25.8% for mental distress diagnosed by the GP. In the multivariable analyses significant association was found for depression/anxiety and work intensity, emotional demands and social relations at work. Excessive alcohol consumption was associated with social relations at work and autonomy. For suicidality, there was an association with work intensity in men and emotional demands in women. The prevalence of work related mental distress found in our study was high and emphasize the major role of GPs in the management of these patients. Several psychosocial factors at work were associated with mental distress which shows the impact of those work characteristics on the presence of mental distress

Повний текст джерелаHigh prevalence of childhood overweight and obesity associated with health consequences at short and long term highlight the need for improved prevention and care. The objective of this research work was to study the factors associated with overweight, in young children, on one hand, and in adolescents on the other. In young children, we have shown the importance of family antecedents of overweight and diabetes, early weight status and environmental factors (particularly television viewing). In adolescents, we have shown that overweight was negatively associated with family affluence, daily breakfast consumption and practicing physical activity. Television viewing was also associated with overweight in girls only. The etiology of overweight is complex. Better understanding of the determinants of overweight in children could assist in formulating multi-disciplinary approaches for prevention and care of overweight

Повний текст джерелаBACKGROUND: Assessment criteria which take patients’ perceptions into account, such as quality of life, are becoming increasingly important in health services assessment and policy and clinical decision-making. Despite the fact that mental disorders represent a significant burden in terms of prevalence and economic consequences, there is a lack of knowledge regarding quality of life of patients cared for by mental health care services which impedes informed decision-making in the field of psychiatry.OBJECTIVES: Our objectives were to measure quality of life using utility scores of people cared for by mental health care services in France; to assess the loss of quality of life attributable to mental disorders; and to identify factors associated with quality of life.MATERIAL AND METHODS: After a literature review describing quality of life tools used in the field of mental health, we undertook a survey to measure the quality of life of people suffering from mental disorders who were treated in the general psychiatric sector using two tools and the corresponding utility scores: the SF-36, allowing calculation of utility scores by the SF-6D, and the EQ-5D. We compared them in terms of performance, and we assessed their consistency. We evaluated the quality of life loss attributable to mental disorders considering data from the French general population-based survey on health and disabilities as a reference. Finally, we used several models adapted to the specificities of the utility score distributions to identify socio-demographic, clinical and mental health care utilization characteristics associated with quality of life.RESULTS: 212 patients were included. The mean utility score was 0.684 when assessed by the SF-6D, and 0.624 when assessed by the EQ-5D. Utility scores of patients suffering from mental disorders were 11% lower than those of the general population. Being a woman and being severely ill were factors associated with lower utility scores using both tools. In comparison with no hospitalization, voluntary hospitalization within the past 12 months was associated with lower SF-6D utility scores, whereas part-time hospitalization was linked with higher SF-6D utility scores. SF-6D and EQ-5D utility scores showed poor agreement in measuring quality of life. These instruments were similar in terms of acceptability as well as discriminant and convergent validity; however, the EQ-5D showed lower sensitivity, illustrated by a ceiling effect, and the models used to study factors associated with this score showed poor performances.CONCLUSION: We objectivized the negative impact of mental disorders on quality of life. Considering the significant differences identified between the SF-6D and EQ-5D utility scores, the choice of the most adapted instrument constitutes a major issue. The lack of sensitivity of the EQ-5D and the difficulties experienced in finding a model adapted to the specificities of this score would suggest that the SF-6D is better suited to the field of mental health. However, our results must be confirmed by analysis on larger samples

Повний текст джерелаThe parenting of psychotic mothers has become a social reality more frequent since the advent of neuroleptics and the development of extra-hospital care, but it remains little studied. Most research focuses on the risk factors and disabilities of mothers with psychotic disorders. To better understand the experience of parenting psychotic mothers, we conducted a research, combining qualitative and quantitative methods, with 18 mothers diagnosed with psychotic disorder and followed in adult psychiatry. We also interviewed 16 health professionals practicing in psychiatry to know their point of view and their representations on these parenting and their follow-up. We took a new perspective, focusing on the protective factors and the resilient process of psychotic mothers. We wanted to highlight the environmental factors that can help these mothers in their parenting role and explore their specific needs. Psychotic mothers and health professionals responded to a semi-directive interview. 6 scales were also submitted to the mothers to provide additional results to their testimony (SUMD disorder awareness scale, PSI parental stress scale, SSQ6 social support scale, RQ relationship attachment scale, PACOTIS parenting competence scale and RSA resilience scale). The results show that despite difficulties in managing the symptoms and the daily lives of their children, these mothers say they are satisfied with their parenting role. Nevertheless, the score on the parental stress scale is high among all of these mothers interviewed and the majority of mothers feel lonely and stuck in their role, while they all benefit from a particular support (family or professional). Although these aspects may be a negative aspect of their parenthood, it seems to be a protective factor in itself. Indeed, it promotes the search for social support, the monitoring of medical treatment and the feeling of having meaning in their lives. The results also show a strong positive correlation between the resilience score and the impression of being a good parent. The role of the environment is paramount in these situations. Yet many judgments are felt, especially during the announcement of pregnancy and can slow down the demand for help. The testimony of the professionals shows the representations existing around this question. While all professionals perceive the difficulties of these mothers, parenting skills are difficult to identify. This question seems little mentioned by adult psychiatry professionals for lack of interest or knowledge. However, as for the interviewed mothers, the professionals confirm the importance that this problem be treated by the psychiatric services. Specific accompaniments around parenting or training schemes were considered. The confrontation of the experiments also shows the limits related to the organization of the services and representations which make the handling of this problematic complex. These results therefore suggest the importance of an ecosystem approach to these parenting situations in order to foster a process of resilience for these mothers and families. Finally, they highlight the need to question new approaches that focus on the individual rather than the symptom such as empowerment or recovery programs so that mothers can develop their full inner potential

Повний текст джерелаNeutrophil elastase (HNE), proteinase 3 (Pr3) and cathepsin G (Cat G) are serine proteases massively secreted in the airways by neutrophils during lung inflammatory diseases and implicated in the degradation of pulmonary constitutive proteins and in the perpetuation of inflammation. In order to develop an anti-inflammatory therapy based on the administration of antiproteases by aerosol, the objectives of the thesis were to validate and optimize the therapeutic potential of two inhibitors of HNE and Pr3: elafin and its precursor named trappin-2. The study of proteolytic susceptibility of the two molecules and their immobilization to extracellular matrix proteins has confirmed their therapeutic potential. In addition, design of a polyvalent inhibitor derived from trappin-2 and targeting HNE, Pr3 and Cat G give interesting therapeutic prospects

Повний текст джерелаIn the Part A, the Chapter 1 presents schizophrenia and the subjective quality of life, rarely considered in this population. The reliability of subjective quality of life assessment has been frequently criticized because of the frequent lack of insight in schizophrenia. This chapter highlights the following paradox. On one hand, the empowerment policies induce the consideration of the subject as playing an active role with regard to the treatment that they receive, whereas, on the other hand, the lack of insight can limit or prevent therapeutic engagement. Chapters II and III present classical conceptualizations of clinical insight in schizophrenia (definition, assessment, models). Among the classical models, predictors of insight have been mostly investigated in terms of personal (e.g. cognitive resources) and clinical factors (symptoms). These studies have gradually integrated moderating or mediating factors since data about linear relationships between insight and classical factors were inconsistent. However, models are essentially based on the subject abilities, without taking into account the interactional process involved in insight. The Chapter IV presents studies investigating associations between insight and clinical outcomes. This chapter highlights the debate still active on the cost/benefit potential balance of a therapeutic intervention focused on insight. Here again, consensus is lacking. Interpersonal factors might also give crucial information to define more thoroughly the conditions of interventions focused on insight. The Chapter V describes the few international studies dealing with insight and interpersonal factors. Only personal characteristics involved in interpersonal relationships (e.g. social cognition) have been studied as predictors of insight. The close environment characteristics that are involved in interpersonal relationships have been partially questioned in order to explain relationships between insight and clinical outcomes. Very few studies have been focused on interpersonal variables that could explain relationships between insight and subjective quality of life. The Chapter VI presents the two main objectives of this work. Through a cross-sectional study, we explored whether including interpersonal factors i) in explanatory models of insight, ii) in explanation of relationships between insight and subjective quality of life could be relevant. The Part B gives details about the method, the procedure and the different analyses that have been conducted in order to explore these questions. The Part C presents sample characteristics and significant results of analyses. These results are compared to those of international research. Interpersonal factors significantly improved the quality of classical insight models, whatever the assessment method (self-reported versus expert-rated insight). However, depending on the assessment method, distinct interpersonal factors were identified. Finally, results suggest that several interpersonal factors moderate the relationships between insight and subjective quality of life. Finally, the Part D discusses the main results of this work, insisting on the limits of the present research and giving some perspectives for future research. Four points for clinical interventions on insight are developed, each integrating interpersonal factors as therapeutic lever

Повний текст джерелаRealized from a corpus of archives of more than one thousand documents, this thesis includes two parts, the first one is about Joseph Merklin's career from his birth in Oberhausen (Germany ) in 1819 to his death in Nancy in 1905. The second one is especially devoted to the life of the firm from the beginning in Brussels in 1843 to the liquidation in Lyons in 1976. The story of the house of Daublaine-Callinet, bought by J. Merklin in 1855, brings some essential materials to understand how Merklin gained a firm footing in France. The life of the firm is permanently connected with the economic, cultural and political context of the French industrial society of the second part of the nineteenth century. In this analysis can be found the role of the national and universal exhibitions, the story of the organ committee and the study of the market of the cathedral organs. The list of all the patents of invention concerning the organ building registered in France from 1791 to 1900 (chronological classification of the patents and alphabetical classification of the patentees) allows us to understand the role played by Joseph Merklin in the race towards progress and to minimize the problem of the use of electricity in organ-building. A lot of unpublished letters from Widor, Saint-Saens, Franck, Guilmant, Dallier, Batiste, Gounod, Dubois. . . Gives an idea of the high reputation of the house and show the intimate links Joseph Merklin had created with the most eminent musicians of his time

Повний текст джерелаThe goal of the PhD thesis project was to investigate the molecular basis of a particularly interesting phenomenon that occurs in the brown alga Ectocarpus: the alternation, during the life cycle, between two independent, heteromorphic organisms, the sporophyte and the gametophyte. A UV mutagenesis approach had previously been used to screen for life cycle mutants in Ectocarpus. One mutant was isolated, ouroboros (oro), in which the sporophyte generation of the life cycle developed as a fully functional (gamete producing) gametophyte. Consequently, individuals that carry the ouroboros mutation exhibit a homeotic conversion of the sporophyte into a gametophyte. Genetic analysis of the mutation had shown that it was a recessive, single-locus mutation. Also, it had been established experimentally that the mutant shares morphological and functional features which are typical of the wild type gametophyte. Left unaddressed was if oro resembles the wild type gametophyte at the molecular level. I used generation markers genes to show that oro resembles wild type gametophyte at the molecular level. In order to identify the ORO gene, a map-based cloning strategy, using Amplified Fragment Length Polymorphism (AFLP) and Simple Sequence Repeats (SSR) markers, was used. Linkage analysis placed the ORO locus on the linkage group 17. Fine genetic mapping with 1566 individuals of a mapping population delimited the ORO locus to a 43 kbp genomic DNA region with four genes in the region. Sequencing, annotation and function prediction of genes in this region using the sequenced genome of Ectocarpus and comparing it with whole genome sequence of a strain carrying the oro mutation identified a transcription factor gene, which is a strong candidate for the ORO gene. I also participated in a project that focused on understanding the non cell autonomous regulation of life cycle transitions in Ectocarpus. Specifically using life cycle generation marker genes, I showed that meiospores grown in the presence of a sporophyte-produced diffusible factor develop into functional sporophytes and resembled the wild type sporophyte at the molecular level. The results obtained from this work provided a solid foundation for map based cloning of the ORO gene and increased our understanding of the molecular mechanism underlying alternation of generation in Ectocarpus

Повний текст джерелаTo be in line with the standard of operational amplifier (opamp), designer integrates in his circuit several functionalities like a Rail to rail input and output, class AB output stage and low power consumption. For standard products, there is no outstanding performance but the average of all of them has to be good. In order to increase the number of functions on an integrated circuit, the power supply and current consumption are permanently decreasing. The aim of the designed circuits is to double the figure of merit (FOM) of the actual ST portfolio products. The FOM allows the comparison of similar opamps. It is defined by the ratio of the product of capacitive load x gain-bandwith product over the power consumption. The opamps’ state of the art has led this study to three stages analog cells. A DC gain higher than hundreds of decibel is required to use opamps in feedback configuration. As each stage of the structure introduces a high impedance node and as each high impedance node introduces a pole, the study of frequency compensation technics became essential for well optimized structures. To simplify the study of the opamps, three tools have been developed to help in the design of the frequency compensation network and to automate some tasks. This work has been followed by the realization of six cells. Three of them were designed to validate frequency compensation structure and the other three to satisfy a standard opamp datasheet. Nested Miller, Reversed Nested Miller and Multipath Nested Miller compensations were used in these circuits

Повний текст джерелаPost-stroke depression (PSD) is one of the most common psychiatric complications following stroke with detrimental consequences in terms of functional recovery and quality of life. Its identification and treatment at the earliest stages of care remains a clinical challenge. The aim of this thesis is to study risk and protective factors for PSD based on data collected in the contexts of daily life. In the first section, we present a study of the role played by social support and routinization on the severity of depressive symptoms three months after stroke by Ecological Momentary Assessment (EMA). In the second section, we examine the voice as an early marker of PSD. We observed that patient perceptions of better support quality, and not quantity, immediately following mild stroke, are associated with better behavioral and emotional outcomes three months later. In addition, we observed a unidirectional pattern of association between mood and routines, whereby the occurrence of routines was associated with a higher level of depressive symptomatology over subsequent hours. Finally, voice analysis allowed us to identify PSD markers with longitudinal changes in fundamental voice frequency and discriminant analysis demonstrated that initial voice breaks coupled with shimmer are strongly predictive of subsequent PSD. Beyond commonly-recognized clinical risk factors such as stroke severity, these ecological investigations identified new markers for PSD whose detection could lead to new strategies for prevention and care

Повний текст джерелаThe @aim of our laboratory is to synthesize functionalized biomaterials. The accomplishment of these materials is made by addition of a system of prolonged of peptide incorporated on calcium phosphate coatings. This lipopeptide has the capacity to activate latent TGF-beta. Once activated, TGF-beta acts as stimulator of bone formation but these effects change depending on the cell type and concentration of TGF-beta. The firs part of our work consists of study the effects of TGF-beta on human osteoblasts during their kinetics of differentiation. The second part shows the real capacity of Ea-KRFK lipopeptide to activate latent TGF-beta in human osteoblasts. And to finish, we have showed the biocompatibility of a calcium phosphate coating made by electrodeposition aimed t be used for the functionalisation of biomaterials. To conclude, we have showed that the lipopeptide is a good candidate for the encapsulation in view of a prolonged release and that the coating was a good material for the functionalisation

Повний текст джерелаObesity is strongly implicated in the aetiology of endometrial cancer, but little is known of the association of other lifestyle and metabolic factors with endometrial cancer risk. This thesis examines the aetiological role of factors related to energy balance and insulin-resistance on endometrial cancer risk. Studies were conducted within the European Prospective Investigation into Cancer and Nutrition (EPIC), a prospective cohort study comprising about 350,000 women and 150,000 men in 10 western European countries. Several lifestyle factors were examined, including anthropometry, physical activity and dietary carbohydrates, as well as metabolic factors measured in the blood, such as insulin, adiponectin, glucose and lipids. To complement the aetiological analyses, a physical activity validation study was conducted in Sydney, Australia, to explore the validity and reliability of the EPIC physical activity questionnaire, using accelerometers as an objective measure

Повний текст джерелаDepuis les cinquante dernières années, les maladies cardiovasculaires (MeV) représentent la principale cause de décès dans la plupart des pays industrialisés. Malgré le fait que la compréhension des mécanismes sousj acents à ces pathologies, tout comme la qualité du traitement offert aux individus à haut risque de Mev ne cessent de s'améliorer, la morbidité cardiovasculaire diminue très peu et tend même à augmenter dans certaines populations. Plusieurs ont démontré que l'augmentation de la prévalence de l'obésité (particulièrement de l'obésité abdominale) et de la sédentarité pourrait, en partie, expliquer cette observation lourde de conséquences pour les systèmes de santé à travers le globe. Il est maintenant bien reconnu qu'une accumulation de tissu adipeux intra-abdominal ou viscéral est associée à plusieurs complications ± cardiométaboliques¿ qui augmentent le risque de MeV. Parmi ces complications, on retrouve entre autres une perturbation du métabolisme des lipoprotéines et des lipides, un état pro-inflammatoire et une perturbation de l'homéostasie du glucose et de l'insuline. Il est maintenantreconnu que les individus avec obésité viscérale sont caractérisés par de petites particules LDL et HDL. Les travaux de ce présent projet de doctorat ont permis de démonter que les hommes et les femmes caractérisés par ce phénotype ont un risque élevé de Mev. Par ailleurs, nous avons démontré que la sédentarité et l'ob.ésité abdominale augmentent le risque de MeV dans une vaste étude de population européenne. Nous avons également soumis l'hypothèse qu'un profil inflammatoire détérioré pouvait représenter un lien entre ces phénotypes et le risque de Mev. En conclusion, le présent projet de doctorat a démontré qu'au-delà des facteurs de risque traditionnels de MeV, plusieurs facteurs/marqueurs de risque ± en émergence¿ pourraient être utiles afin de raffiner la prédiction du risque de Mev en prévention primaire. Les prochains outils cliniques permettant l'estimation du risque de Mev devront prendre en considération certaines complications associées à l' obésité abdominale.

Повний текст джерелаFluorescent in situ hybridization using pancentromeric DNA probes was combined with the cytokinesis-block micronucleus (MN) assay to determine: (i) chromosome damage (MN frequency and number of centromeric signals) in peripheral lymphocytes of occupationally exposed workers, cancer patients and healthy donors, (ii) their modulation due to occupational exposure, smoking habit, alcohol consumption, age, gender, and genetic polymorphisms. Two alternative pathways of chromosome loss would exist: impaired chromosome migration, leading to increased monocentromeric MN, and centrosome amplification, possibly leading to multicentromeric MN. Scoring the number of centromeric signals provides additional information about the mechanisms of cellular dysfunctions in the origin of centromeric MN, may improve the sensitivity of the MN assay in detecting environmental effects and chromosome instability, and would more specifically define the prevention and/or prediction of cancer risk with this assay

Повний текст джерелаPhysical activity is a protective factor for common chronic diseases, while sedentary behavioris a risk factor. Among the different domains of habitual physical activity, active transportation (walking, cycling) is a topic of growing interest. A better understanding of the determinants and health effects of physical activity and sedentary lifestyles is essential to develop public health interventions targeted for at-risk populations. The objectives of this thesis were to investigate some individual factors associated with specific domains of walking and cycling, and to explore the relationship of specific areas of sedentary lifestyle with health outcomes, taking into account the effects of habitual physical activity. We measured physical activity and sedentary behavior cross-sectionally with questionnaire in the NutriNet-Santé French adults cohort (n = 39,295 subjects) and longitudinally in the SU.VI.MAX cohort (n =2,841). Our results indicate that the different domains of walking (commuting, leisure andutility) and their relationships with individual factors are not homogeneous, that during the transition to retirement the decrease in occupational physical activity was not offset by newly developed behaviors, and finally that specific physical activity and sedentary lifestyles could affect cardiometabolic risk factors and excessive daytime sleepiness. These results should contribute to a better understanding of the health behaviors of the French population, in order to better target preventive and health promotion interventions
