Full textAging is a complex process characterized by the progressive alteration of cellular and tissue physiology. Modulated by genetic and epigenetic factors, it is accompanied by a modification of the cellular metabolism, a decrease in resistance to various cellular stresses and cellular senescence. The objective of this work is to use cell reprogramming as a strategy to delay the effects of aging by inducing global rejuvenation or by improving the regenerative capacities of the organism.The expression of four transcription factors: OCT4, SOX2, KLF4 and c-MYC (OSKM) allows the induction of somatic cell reprogramming into pluripotent cells. This so-called transient reprogramming, i.e., initiating the process without leading to the pluripotent state, has an immediate effect that partially erases the characteristic marks of tissue and cell aging. In order to determine how an early short transient cellular reprogramming affects aging processes in a whole animal, we induced OSKM expression in young progeric reprogrammable mice and revealed an increase in longevity at late ages and a protective effect on the integrity of tissue structures and on age-related pathologies, associated with modifications of epigenetic signatures in tissues. These results on late ages after an early transient reprogramming suggest a memory effect maintained throughout life. To explain these long-term effects, we explored the impact of an early transient reprogramming on metabolism. We were able to demonstrate a global modification of the body composition of the animals with a decrease of the fat mass gain in the young ages and a maintenance of this same fat mass in the late ages associated with a global modification of the ultrastructure and the metabolic activity of the white adipose tissue. This metabolic transition also seems to impact the muscle tissue with its own dynamics.The identification of the underlying mechanisms will allow us to define new strategies to prevent aging and senescence, which are at the origin of the appearance of age-related pathologies

Full textThe research of this PhD thesis is fulfilled in the context of wearable video monitoring of patients with aged dementia. The idea is to provide a new tool to medical practitioners for the early diagnosis of elderly dementia such as the Alzheimer disease. More precisely, Instrumental Activities of Daily Living (IADL) have to be indexed in videos recorded with a wearable recording device.Such videos present specific characteristics i.e. strong motion or strong lighting changes. Furthermore, the tackled recognition task is of a very strong semantics. In this difficult context, the first step of analysis is to define an equivalent to the notion of “shots” in edited videos. We therefore developed a method for partitioning continuous video streams into viewpoints according to the observed motion in the image plane.For the recognition of IADLs we developed a solution based on the formalism of Hidden Markov Models (HMM). A hierarchical HMM with two levels modeling semantic activities or intermediate states has been introduced. A complex set of features (dynamic, static, low-level, mid-level) was proposed and the most effective description spaces were identified experimentally.In the mid-level features for activities recognition we focused on the semantic objects the person manipulates in the camera view. We proposed a new concept for object/image description using local features (SURF) and the underlying semi-local connected graphs. We introduced a nested approach for graphs construction when the same scene can be described by levels of graphs with increasing number of nodes. We build these graphs with Delaunay triangulation on SURF points thus preserving good properties of local features i.e. the invariance with regard to affine transformation of image plane: rotation, translation and zoom.We use the graph features in the Bag-of-Visual-Words framework. The problem of distance or dissimilarity definition between graphs for clustering or recognition is obviously arisen. We propose a dissimilarity measure based on the Context Dependent Kernel of H. Sahbi and show its relation with the classical entry-wise norm when comparing trivial graphs (SURF points).The experiments are conducted on the first corpus in the world of wearable videos of IADL for HMM based activities recognition, and on publicly available academic datasets such as SIVAL and Caltech-101 for object recognition

Full textThe prognosis of childhood-onset chronic conditions has improved, such that more patients now reach adulthood. However, adolescence and entry into adulthood is a critical period that may be associated with poor outcomes, including gaps in care continuity and medical complications. Here, I first described hospitalization and mortality rates in youths registered for a long-term disease (LTD) before the age of 14 (N=1,752), relative to those with no LTD (N=52,346). A retrospective cohort (2005-2014) was built from a sample of the French national health insurance database, called Echantillon généraliste des Bénéficiaires. Approximately 3% of 14-year-old youths had been registered for a LTD. The mortality patterns by gender and the trend in hospitalization rates by age were different from those in the general population of the same age, especially after reaching the age of 18, which was followed by a fall in hospitalization rates. Then, using the same data, I showed that the prognosis of these youths living with a chronic disease, including mortality, was associated with low socio-economic level, as measured by being covered by Couverture Maladie Universelle Complementaire, a public complementary health insurance offering free access to care, delivered on the basis of very low househould incomes. Hence, overcoming financial barriers did not offset social health inequalities in this population. At last, one day, these youths have to be transferred to adult care. Moving to adult care is a critical time in patients’ follow-up that may lead to discontinuity in medical care. Transition programs are being gradually implemented, to prepare and smooth the transfer and support youths during this period. I performed a systematic review of literature (23 studies) that highlighted two aspects of continuity of care during transfer: engagement (first contacts) and retention in adult care once the first contact has been established. This review also emphasized the paucity of knowledge to evaluate transition programs in terms of care continuity. Finally, the results of this PhD raises many issues that need to be addressed, including coping strategies of young patients with high risk situations, and the role of transfer to adult care on patient behavior, prognosis and clinical practices. Studies involving patients with a large spectrum of severe chronic diseases, including factors related to healthcare organization, related to the disease, individual and familial, should be encouraged

Full textAortic valve stenosis (AS) is a degenerative pathology of the aortic valve that affects 2 to 4% of the population over 65 years of age, and 4,6% of people over 75 years of age. This pathology results in a thickening and stiffening of the aortic valve leaflets, leading to an impaired opening, and closing of the valve. The risk factors for developing AS are bicuspid valve (a congenital anomaly affecting 1 to 2% of the general population), age, dyslipidemia, and male sex. The mechanisms involved in the pathophysiology of AS are relatively well known. Mechanisms involved in inflammation, fibrosis, calcification, survival, and cell proliferation are found. However, despite an important bibliography on the pathophysiology of AS, very little research has been done on the impact of sex and sex hormones on the progression of AS. It has recently been shown that for the same hemodynamic severity of AS, men have a higher degree of calcification and a lower proportion of fibrosis of their valve than women. Thus, the objective of this master is to study the impact of sex, valve phenotype and age on the degree of calcification and valve remodelling in human patients for whom we had their clinical characteristics as well as CTscan data and explanted valves. Results obtained shown that women, regardless of valve phenotype or age, will have a lower degree of valve calcification and a greater fibrotic remodelling of their valves than men. In addition, in bicuspid patients, young women have a less calcified aortic valve compared to older women.

Full textHuman mitochondrial aminoacyl-tRNA synthetases (mt-aaRSs) are housekeeping enzymes involved in the mitochondrial translation. They catalyze the aminoacylation of tRNAs with their cognate amino acids. Mutations in their nuclear genes are correlated with pathologies with a broad spectrum of clinical phenotypes, but with so far no clear explanations about the underlying molecular mechanism(s). The aim of this PhD work follows the long-standing efforts of the host laboratory but expand the interest and knowledge to an unexplored system: the human mitochondrial arginyl-tRNA synthetase (mt-ArgRS). Mutations in the mt-ArgRS lead to Pontocebellar hypoplasia type 6, a severe neuro-developmental pathology. I thus contributed to i) comprehensively analyze the clinical data reported in pathologies related to mutations on mt-aaRSs, resulting in a categorization according to the affected anatomical system; ii) decipher some cellular properties of the mt-ArgRS; and iii) investigate to impact of disease-associated mutations on mt-aaRSs properties. Combined with previous works, the present results expand the knowledge of the mt-aaRSs, shedding new light on the link between mt-aaRSs-mutations and disease
Goven, Delphine. "Régulation de l’hème oxygénase-1 dans les macrophages au cours des pathologies pulmonaires liées à l’exposition de la fumée de cigarette." Thesis, Paris Est, 2009. http://www.theses.fr/2009PEST0051.
Full textChronic cigarette smoking, a source of oxidants, is an important risk factor for lung emphysema and primary spontaneous pneumothorax development. Alveolar macrophages are mainly involved in lung inflammation observed in these pathologies through the production of metalloproteases and reactive oxygen species resulting to protease/anti-protease and oxidant/anti-oxidant imbalances. Heme oxygenase-1 (HO-1), mainly expressed in macrophages, is a key enzyme in pulmonary anti-oxidant defences. Therefore, the first aim of our studies was to investigate the expression and cellular localisation of HO-1 and its potential regulators (Nrf2, Keap1, Bach1 and HIF-1a) in alveolar macrophages from smoking related lung emphysema and primary spontaneous pneumothorax. Regulation pathways involved in expression of these proteins were assessed in vitro in macrophage cell line THP-1 exposed or not to cigarette smoke condensate and with or without hypoxia-reoxygenation mimicking parts of events induced by atelectasia-reexpansion during recurrent pneumothorax constitution and treatment. In these studies, we showed an altered expression of Nrf2/Keap1- Bach1 pathway associated with a reduced expression of anti-oxidants enzymes, like HO-1, in alveolar macrophages from smoking related lung emphysema patients, despite an important oxidative stress. These alterations might be related to cigarette smoke condensate activated ERK1/2 and JNK MAPKinases as observed in THP-1 cells. Furthermore, we showed that HO- 1 system induction was mediated by HIF-1a instead of Nrf2 pathway in alveolar macrophages from smoking related recurrent primary spontaneous pneumothorax. These findings may contribute to a better knowledge of the pathophysiology of lung emphysema and could provide new therapeutic approaches based on preservation and/or restoration of Nrf2/Keap1-Bach1 equilibrium. Our results also suggest that the pathophysiology of primary spontaneous pneumothorax could be different in smokers and non smokers. Spontaneous pneumothorax in smokers is associated with lung oxidative stress and the orchestrated induction of HO-1 probably via HIF-1a. These results provide a new link between oxidative stress and hypoxia/reoxygenation

Full textGlycosylation is one of the most main types of post-translational modifications of proteins. Disease-associated modifications in protein glycosylation have been observed for various pathologies such as cancer, rheumatoid arthritis, or «Congenital disorders of glycosylation» (CDGs). They are often exploited for diagnosis, prognosis and monitoring of these diseases. This thesis work focused on the glycosylation study with the aim to allow the screening of different pathologies: CDGs, Alzheimer’s disease and retinal degeneration diseases. Different strategies based on capillary electrophoresis (CE) were considered to fulfil this goal. First, the developement of a CZE analysis of intact apolipoprotein C-III (ApoC-III), an O-glycoprotein implied in the screening of O-glycosylation disorders, allowed the separation of its glycoforms according to their sialylation degree. The MALDI-TOF mass spectrometry (MS) analysis of standard ApoC-III batches from different standard ApoC-III batches from different suppliers highlighted an additonnal heterogeneity due to (unexpected) carbamylated species. A plasma pretreatment based on an immunocapture of apoC-III followed by protein derivatization on magnetic beads using a fluorophore allowed to separate its glycoforms by CZE. Second, a glycomic analysis of biologicial fluids using a new sample treatment method that we adjusted to plasma and cerebrospinal fluid samples was performed by CGE-LIF on controls and Alzheimer’s patients. It allowed to highlight some modifications of N-glycans for this disease. Finally, the combination of both strategies of glycosylation analysis (intact glycoprotein and released N-glycans) allowed the detection of intact transferrin present in vitrous humor but also of its released N-glycans for the screening of retinal degeneration disease. CE-QTOF-MS was also investigated for the analysis of released N-glycans derivatized by a new fluorophore which increases MS sensitivity
