Full textThe lung is an organ whose the role is to transport oxygen from the ambient air to the blood and to extract carbon dioxide from the blood. It is a tree-like structure of bronchi, the bronchial tree, connected to an exchange surface, the acini.The bronchial bifurcations are asymmetric: the bronchi divides into two daughter bronchi of different sizes. The topology of the tree is asymmetric : the number of bifurcations that connect the trachea to the acini is not constant. The bronchi wall is deformable (compliance) and their geometries are affected by the transmural pressure, i.e., the pressure difference between the surrounding tissue and the air flowing inside the bronchi. These characteristics affect the hydrodynamic properties of the tree.As an interface with the external air, it is constantly in contact with external particles. The bronchial mucus plays a protective role by capturing these particles. Normally, the mucus is naturally drained out of the lung. The mucus should not stagnate in the bronchi because stagnation increases the probability of developing an infection. When stagnation occurs, chest physiotherapy is often prescribed. The physiotherapists usually perform technics using the air shear stress to stimulate the mucus extraction. However, the expiratory conditions that allow to mobilize the mucus are not clearly defined.This thesis is based on three steps that allow to analyze the influence of the bifurcations asymmetry and of the compliance on the distribution of the shear stress induced by the airflow in the bronchi. Our three studies use a 0D model for each bronchus. The air hydrodynamic into each bronchus is simplified, either with a Poiseuille flow or with a “modified Poiseuille” flow that includes some inertial effects.The first step consists in understanding the air shear stress repartition in a symmetric tree with compliant bronchi. We show that this repartition exhibits a maximum whose location and amplitude depend on the flowrate in the trachea and on the pressure in the pulmonary tissue. This study shows also that one partial obstruction might “hide” others localized deeper in the lung. The comparison of our results with a typical yield shear stress of the mucus allows to develop, in the limits of our model, idealized chest physiotherapy technics for mucus draining.The second step aims at understanding the link between the bifurcation’s asymmetry and the hydrodynamics in a fractal and rigid tree. We propose in this part the hypothesis that the pulmonary asymmetry selection is linked to the optimization of a cost linked to the tree’s hydrodynamic resistance, under a constraint on the tree’s volume. Our analysis allows to propose a scenario that explains the difference in asymmetry observed between mammals.Finally, the third step aims at studying the shear stress repartition in a tree with asymmetric bifurcations and compliant bronchi. We show that the distribution of the air shear stress induced by a Poiseuille flow in trees with symmetric bifurcations and with asymmetric bifurcations have similar behaviors. However, the asymmetric case presents a spread of the shear stresses in the distal part of the tree, and bronchi with similar properties can have very different shear stresses.This research, based on the alliance of mathematics, physics, biology and medicine, allowed to improve our understanding of both the bifurcation asymmetry, the bronchi compliance and their effect on the airflow hydrodynamic. Particularly, this allowed to further understand the influence of the air shear stress on the mucus flow during chest physiotherapy

Full textThe objective of this thesis s to develop a 3D+t reconstruction algorithm taking advantage of ail the spatiotemporal known about the respiratory movement in order to produce a reconstructed image compensated from the respiratory motion using ail the statistics. In ail this study, List-mode raw emission data were reconstructed using the iterative OPL-EM algorithm (“One Pass List Mode-EM). For both proposed methodologies based on affine or elastic correction methodologies, the transformation parameters were calculated from dynamic CT or PET images reconstructed with and without attenuation correction and were subsequently applied directly to the list-mode emission data or integrated during the reconstruction process. Three different ways to incorporate the elastic transformations matrices during the QPL-EM reconstruction algorithm have been developed and evaluated. To evaluate the developed methodologies Monte-Carlo simulations based on the dynamic NCAT phantom, including a breathing movement, have in the first instance been performed. The final phase of the evaluation was based on an analysis of actual multi-modality clinical cases. The results of this work show that the two types of proposed corrections, affine or elastic, lead to significant improvements as a result of the breathing movement compensation in the lung field of view. However, this study demonstrates that the correction method based on an elastic transformation yields a more uniform improvement in the whole field of view, whatever part of the lungs is considered

Full textLung cancer is the leading cause of cancer death among men and women worldwide. Despite the major advances in the treatments, platinum-based therapy remains the standard of care for patients affected by KRAS-driven lung cancer. Even though the platinum-compounds display an initial effect on these patients, the onset of the relapse constitutes the main challenge for the clinic. The molecular mechanisms underlying lung adenocarcinoma (LUAD) relapse are not completely elucidated yet, thus it is fundamental to understand them in order to improve survival of patients. Our data show that upon carboplatin treatment, the Notch pathway is activated in vitro. Since this effect was common for several other DNA damage insults, our driving hypothesis connected the DNA Damage Response (DDR) to the activation of the Notch pathway. Our data demonstrates that protein kinase ataxia telangiectasia-mutated (ATM) is a key mediator in the activation of the Notch pathway during DNA damage signalling. ATM is well-known as the chief mobilizer of the cellular response to the most toxic lesions to the DNA, the double-strand breaks which are also the type of damage caused by the conventional chemotherapy. Among the several substrates of ATM in response to the damage, there is the mouse double minute 2 protein (MDM2) that it is known to interact with the Notch pathway. Our data uncovered a new pathway connecting ATM, MDM2 and NICD during carboplatin treatment in LUAD cells.Using LUAD Patient-Derived Xenografts and a new generated carboplatin resistant cellular model, we show in vivo that the combination of Notch and MDM2 inhibitors with carboplatin showed a therapeutic benefit in tumour growth and survival compared to the standard of care, i.e. carboplatin.Our results can offer a new therapeutic window for KRAS-driven LUAD that become resistant to platinum-based therapy, hence tackling an urgent and unmet clinical need

Full textThis work deals with the design, on a clinical scanner, of new protocols for helium3 MRI and with their application to preclinical and clinical studies. Allowing for a virtually unlimited number of acquisitions, helium3 MRI is well adapted for longitudinal or pediatric studies. Acquisitions, however, are mostly performed under breath-hold, precluding the application to non cooperative patients. The first part of this thesis addresses the use of a free-breathing protocol, validated in vivo on rabbit and optimized using a model of gas exchange. A second study tackles the joint use of helium3 and proton MRI to study acute diseases, using a rabbit model of Acute Respiratory Distress Syndrome. Finally, the third study demonstrates the sensitivity of helium3 MRI and evaluates the influence of chest physical therapy on cystic fibrosis children with normal respiratory function

Full textThis thesis deals with the estimation of a regression function providing the best relationship betweenvariables for which we have some observations. In a first part, we complete a simulation study fortwo automatic selection methods of the ridge parameter. From a more theoretical point of view, wethen present and compare two selection methods of a multiparameter, that is used in an estimationprocedure of a regression function on [0,1]. In a second part, we study the quality of the PLS1estimator through its quadratic risk and, more precisely, the variance term in its bias/variancedecomposition. In a third part, a statistical study is carried out in order to explain the geneticsignature of cancer cells thanks to the genetic signatures of cellular subtypes which compose theassociated tumor stroma

Full textIn the era of personalized medicine, genomics and targeted therapies, the availability of quantitative tools assisting the interpretation of medical images is essential. In Positron Emission Tomography (PET), beyond measurements of uptake intensity, it is possible to derive quantitative index characterizing the metabolic volume or the tumoral heterogeneity. The objective of this work was to investigate the value of new quantitative indices to enhance PET imaging, allowing for a more comprehensive analysis of the whole tumor. The first part of the work deals with methodological issues associated with the measurement of tumor heterogeneity using textural index. In particular, we identified the most robust and informative textural index for clinical applications. Two sets of patients have then been used to explore the contribution of metabolic volume and texture analysis in PET. In lung cancer patients, our results suggest that the measurement of tumor heterogeneity gives some information regarding the histological features of the tumor. A second set of results shows that metabolic volume is more relevant than conventional indices for evaluating the impact of neoadjuvant chemotherapy in locally advanced stages. A correlation between quantitative changes during treatment and post-treatment histology results was used to demonstrate the relevance of these indices. In breast cancer patients, our results suggest that tumors with aggressive immunohistological patterns, particularly triple-negative phenotype, have a more heterogeneous texture than other types. In summary, our results suggest that a more comprehensive quantitative characterization of the metabolic activity distribution in tumor using PET imaging improves the pre-therapeutic and prognostic evaluation of cancer
