Challita, Jihane. "Study of the mechanisms reponsible for the cohesion of sister chromosomes in bacteria." Thesis, université Paris-Saclay, 2022. http://www.theses.fr/2022UPASL038.
Повний текст джерелаDuring cell proliferation, the maintenance of genetic information is essential. In bacteria, replication and segregation are concomitant. Replication starts at the single, bidirectional origin of replication of bacterial chromosomes. Two replication arms are then defined, and replication ends in a region diametrically opposite to the origin, the terminus. As replication progresses, the newly replicated sister chromosomes migrate to opposite cell compartments. However, microscopic observations suggest that there is a delay between replication and segregation, and that this delay varies along the length of chromosomes. The delay between replication and segregation of the sister copies of a genomic position is referred to as sister chromatid cohesion. During my PhD, I used the high-resolution tool that allows for a genome-wide analysis of Sister Chromatid Cohesion (High-SC2) and studied the cohesion profile of the model organism Vibrio cholerae. It has been shown in E. coli that the cohesion responsible for the variation of segregation speed is modulated by Topoisomerase IV, a major decatenating enzyme. One of the identified partners of this decatenase is an SMC complex, MukBEF. Cells carrying a mukB deletion show a production of anucleate cells, and a mispositioned origin of replication. Chromosome segregation is impaired, and therefore sister chromatid cohesion is increased overall. The Topo IV-MukBEF interaction is regulated by MatP, which seems to displace MukBEF from the terminus of replication, facilitating the association of the MukBEF complex with the origin of replication. I therefore decided to investigate the role of MukB, in the formation of the long-range patterns of cohesion in V. cholerae. Using genetic approaches coupled with the High-SC2 assay, I demonstrated that the deletion of mukB leads to an increase in cohesion on Chr1, especially on its left replication arm, far from the origin. These results suggested that MukB does not preferentially act on specific regions and that the differential effect of the mukB deletion on Chr1 and Chr2 is probably linked to differences in their origin of replication and/or partition systems. Previous observations in the lab have in fact shown that a double deletion of MukB and ParAB1 leads to a strong phenotype, thus I investigated its effect on the cohesion profile. My results show an additional increase of cohesion in Chr1 near the ori, suggesting that the partitioning system acts on the decohesion of the ori domain while MukB acts on the chromosomal arms. In addition, it has been shown that MatP kept the sister-copies of the ter domain of Chr1 together until cell division. I used the Hi-SC2 assay to study its role in the increased cohesion of this region. I showed that MatP was responsible for the cohesion of the ter1 domain at cell division not behind the replication fork, unlike MukB. My results have also shown that it is the density of the matS sites located on the ter domain of each chromosome that influence the level of cohesion of these domains

Повний текст джерелаGenetic information has brought about profound social reform as one of the most important information resources in modern society. The protection of genetic information has concerned benefits of different entities including individuals, families, economic institutions and countries in multiple dimensions, such as private life, market and national strategy. In most of the prior research in this field, genetic information was confused with gene, as the material carrier, tissue samples and other type of personal information, neglecting the particularity of genetic information, or mere questioning of ethics and principles. But it is not enough to resolve the social problems and disputes in the case. This article establishing the vision of rights standard, along the research approach of "fact-theory-system", answers the questions: why protecting genetic information and why taking it as a right (Introduction). The article discusses the object of rights to genetic information(Chapter One), the subject of rights to genetic information(Chapter Two), the attributes of rights to genetic information(Chapter Three), developing the protection principles of rights to genetic information(Chapter Four). Finally, based on the above discussion, the author summarizes and reaffirms that the rights to genetic information is pointing to a new-type right by exploring the practice of protecting genetic information rights. In particular: In the first chapter, the author explores the genetic information, as the right object, in technological transformation. First of all, the paper defines the genetic information which differs from gene with the attributes of information and it must be acquired by Nucleic acid analysis and other scientific analysis. Second, the paper focusing on the social changes brought by genetic information, the author mainly explores the deep implications from technology to thinking-genetic information has been applied into DNA recombination technology, Human Genome Project and bio-pharmaceutical industries bring about great influence to our life through criminal justice and paternity test. Along with the technological innovation and thinking changes, new interests and disputes happened together. At last, the author explains the particularities of genetic information in technological transformation from the objective and subjective aspects

Huang, Ying. "Elaboration of customized maintenance document for complex mechanical products." Strasbourg, 2011. http://www.theses.fr/2011STRA6006.
Повний текст джерелаMaintenance documents are traditionally provided in the form of hardcopy supports for different users like end-users, maintenance technicians and manufacturers. These documents are generally elaborated for a standard product configuration and for general utilization conditions. In the traditional maintenance document, maintenance requirements are often predesigned. Once it is published, it is difficult to be updated to follow the product versions changing or to be adapted according to various Utilization Conditions (UCs). Therefore, the end users or technicians need more time to decide what appropriate maintenance tasks should be accomplished on the new configuration product with a new UC. In order to solve the problems discussed above, a more intelligent maintenance document (dynamic, electronic, customized) is proposed in this thesis which is named Customized Maintenance Document (CMD). The goal of this thesis is to outline a methodology for developing a CMD which shows how to customize the maintenance document for complex mechanical products to be used in different typical contextual conditions, for users with different skill levels and tasks. Three steps are focused in this thesis : knowledge integration process, decision making system design, and document model adoption. After collection and analysis of historical data (such as : utilization condition, structural data and operational data), knowledge is elicited in the form of case and embedded in the system to predict the failure rate of each unit. A multi-model decision making system is designed aiming to help users to find the most ideal maintenance tasks by analyzing the environment in which the complex mechanical product is operating. In order to present information in a better form and take the contextual knowledge into consideration, a semantic document modeling is designed which includes three layers : customized data modules layer, task-oriented document layer, and semantic network layer

Повний текст джерелаTelomeres are the ends of linear chromosomes. Their specific nucleoprotein structure, consisting in repeated DNA sequences associated with specialized proteins, allows cells to distinguish them from DNA double-strand breaks. In Eukaryotes, they are maintained by a specialized cellular reverse-transcriptase, the telomerase. In the absence of telomerase, telomeres progressively shorten with each round of DNA replication until they promote a cycle arrest, termed replicative senescence. This arrest involves the DNA damage signalling pathway. During my PhD, I explored the specificities of the telomeric structure during the shortening process leading to replicative senescence. I discovered that the DNA damage tolerance pathway is involved at telomeres. I also showed that short telomeres accumulate long 3’-single-stranded DNA tails, providing an explanation for the type of signalling and subsequent cell cycle arrest. These short telomeres are also subject to the action of the homologous recombination factors. I found that these factors act in a process that preserves the structure of short telomeres without elongating them, thus ensuring cell proliferation potential after the loss of telomerase

Повний текст джерелаCondition and health monitoring can bring out useful information for the maintenance decision-making but few models allow their integration in the decision process. This thesis aims to construct new probabilistic quantitative models to evaluate the value of this kins of information depending on ith quality and on the nature of the observed variables. The proposed stochastic failure and measurement models take account the degradation/failure sensor data, the impact of operational environment on the degradation, as well as the nature of control techniques. Based on these models, we propose different maintenance policies and we develop the associated cost model to study the best methods for the exploitation of monitoring information. The studies in this thesis show the advantage of developing quantitative maintenance decision framework which allows integrating and evaluating the impact of condition monitoring information on the performance of maintenance operations

Повний текст джерелаThe production and maintenance planning have often been planned separately. Indeed, resources are always considered to be available during the production planning; and preventive maintenance activities are usually scheduled in specific time periods in order to avoid a production interruption. In practice, a bad preventive maintenance policy generates a rise in unplanned shutdowns of production and a reduction of the available resources. Consequently, productivity in the manufacturing plant will be decreased and lead times will no longer be respected. To overcome these issues, we study a new integrated production and maintenance planning problem that combines single level multi-items capacitated lot sizing problem with shortage cost and a maintenance problem where preventive maintenance activities are planned in time windows. Thus, we will model the problem and propose three approaches of finding a solution. The first one is a heuristic based on the relaxation of capacity constraints and a smoothing procedure to find a feasible solution. The second heuristic is based on the Dantzig-Wolfe decomposition and rounding and smoothing procedures to construct a solution. The last approach is a coupling method of a genetic algorithm and a lagrangean relaxation. Various tests are performed in order to show the advantages and limitations of each approach before comparing their respective performances
