Full textUnderstanding how organisms respond to environmental stress has critical implications both on quality of life and treatment of diseases. Organisms have developed a series of sophisticated processes to detect and repair such damages. A family of small proteins called the family of Ubiquitin molecules (Ubls), play a critical role in many aspects of the stress response. Defects in components of the Ubiquitin family are often found in pathologic conditions including cancer and neurodegenerative diseases. Understanding how the ubiquitin family is involved in the cellular stress response is an important step in the understanding of this process and can lead to the development of novel therapeutic approaches to treat diseases caused by malfunction of this system.One of the Ubls that has the highest identity and similarity to Ubiquitin is NEDD8. NEDD8 works in a similar manner to Ub, using a distinct conjugation machinery. NEDD8 modification is essential for maintaining the homeostasis of the cell as it plays a major role in the regulation of viability, growth, and development. Because of that, many components of NEDD8 have been found deregulated in many cancers. NEDD8 can modify a wide range of substrate proteins, including itself, which results in the creation of polyNEDD8 chains. Recently the presence of polyNEDD8 chains has been linked to the regulation of cell death – apoptosis and parthanatos. Moreover, it has been recently reported that NEDD8 during proteotoxic stress can be employed by the Ub conjugation machinery. This results in the creation of hybrid NEDD8 chains where except for NEDD8, we can also find Ub and SUMO, as recent papers have shown that NEDD8 has the ability to modify Ub and SUMO-2. The presence of the hybrid NEDD8 chains was linked with the creation of nuclear aggregates formed during proteotoxic stress, which can play a potential protective role during stress exposure.Knowing how important the regulation of proteins through NEDDylation is, we were also aware of the lack of knowledge about the machinery that plays a role in the creation and deconjugation of different NEDD8 entities. So far two deNEDDylating enzymes were reported but no enzyme was tested for its ability to recognise and process the hybrid NEDD8 chains. Moreover, our knowledge about E3 ligases that are responsible for substrate NEDDylation, even though expanding, is still very limited. Additionally, NEDD8 having ten lysines through which it can modify itself, can generate a very broad range of signals through polyNEDD8 and hybrid NEDD8 chain formation, which can be recognised similarly to polyUb chains, yet no studies have focused on determining their interactors so far.In this work, we focused on exploring the beforementioned unknown elements of the NEDD8 conjugation and deconjugation machineries. Using chemical biology approaches we tested a variety of enzymes and determined that polyNEDD8 chains are exclusively processed by the NEDP1 enzyme, however, deconjugation of hybrid NEDD8 chains requires the coordinated action of different deconjugating enzymes with distinct specificity for Ub or SUMO. We also employed chemically synthesized NEDD8-NEDD8 and NEDD8-Ub dimers in order to look for their interactors and used the gathered data to deepen our knowledge about the biology of hybrid NEDD8 chains in nuclear aggregates. Using NEDD8-Dha probes we identified a group of proteins that are potentially involved in the NEDDylation machinery. Through biological confirmation of obtained results we have shown that tRNA ligases – GARS and SARS are working as NEDD8 E3 ligases. Moreover, RNF20 is also working as a NEDD8 E3 ligase responsible for NEDDylation of histone H2B but also PARP1 – one of the proteins that are key players in the formation of SG

Full textOne main challenge associated with solid-state thermoelectric materials is to combine electron-crystal electrical conductivity and phonon-glass thermal properties that are difficult to conciliate. A markedly different principle of thermoelectric conversion is based on the micro thermionic generator that exploits electron injection and heat rejection across two electrodes, hot and cold, immersed in vacuum, a promising pathway to new electronic devices. To properly operate thermionic emission converters near room temperature, highly efficient emitting electrodes must be integrated. This naturally motivates the development and characterization of thin films that feature a very low work function lower than 1eV. Even better than alkalis like K and Cs, their oxides have been reported to produce work functions as low as 0.4 and 0.9eV respectively. The work function of the electrodes of the micro thermionic generator has been effectively reduced and the efficiency is much closer than the Carnot limit

Full textThe issue of this work is the development of a new miniaturized intra-operative probe that is based on endogenous fluorescence detection. The probe is dedicated to cancer neurosurgery. Ln the future, this autofluorescence technique will be coupled to a radio isotopic probe, yielding an unp~ecedented instrument. Starting with an exhaustive review of medical imaging techniques and in particular of state-of-the-art fluorescence techniques, a section is dedicated to the instrumental development and fust realisations of fibre optic probes. A complete characterisation of their fluorescence spectroscopic performances is given. Afterwards, we show experimental studies of the probes using phantom-tissues with optical properties of mimicking different types of real tissues. Obtained data are compared to Monte Carlo simulations. As a result optimal positioning of the probes above the sample has been determined as weil as the sensitive volume inside the tissue. The influence of the optical parameters has also been measured to optimize fluorescence light collection efficiency and sensitive depth. Finally, the last part of this work de scribes another experimental study where the prototype probes have been used on ex vivo glioma rat mode!. Characteristic spectra have been obtained for various brain regions. Furthermore, different responses are shown for healthy and cancerous tissues. As a result, sufficiently good performances of our device especially in terms of sensitivity for this differentiation have been proven

Full textCurrent depressive disorders are associated with a lower likelihood of quitting smoking and with greater likelihood of smoking relapse.The aim of this thesis project was to study the protective role of physical activity on relapse rate after a smoking-cessation program. Studies 1 and 2 have explored the role of physical activity on relapse at long term in smokers with and without depressive disorders. First study has shown a significant interaction between antidepressant and physical activity as protecteur factor on relapse (n= 227) among smokers recruited at the smoking-cessation unit of Montpellier University Hospital. Second study has confirmed that physical activity was a protector factor on relapse in smokers with depressive disorders. Furthermore, antidepressants, anxiolytics, level of education, and number of attempts to quit were associated with relapse. The efficacy of exercise intervention and counseling as an adjuvant therapy in smoking cessation for smokers with current depressive disorders (n= 70) has been investigated in third study. Compared with control subjects, exercise subjects achieved significantly higher levels of continuous abstinence at the end of treatment (OR = 0.14 ; 95% CI .02 - .72 ; p = .018) while results were not significant at 3 months following treatment (OR = 0.87 ; 95% CI .62 – 1.21 ; p = .08). We have also reviewed the current literature investigating the mechanisms between exercise-depression and exercise-smoking. Methodological and transdisciplinary approaches are proposed to developp future studies

Full textWaking up during surgery is a terrifying experience for patients, who fear it, but also for medical staff, who are worried that the situation will occur under their supervision. This type of phenomenon is called "an Accidental Awareness during a General Anesthesia” (AAGA) and is defined as an unexpected awakening of the patient under general anesthesia. This situation occurs when the general anesthesia is insufficiently deep to compensate all the surgical stimuli related to the surgery. AAGA rate in high-risk practices (e.g. obstetric, cardiac, thoracic) is considered to vary from 1-2%. The problem is that such intraoperative awakening can cause physical pain or lead to psychological sequelae called post-traumatic stress disorder (PTSD). Consecutive PTSDs can last for several years and have serious psychological effects leading to suicide. "I couldn't breathe, I couldn't move or open my eyes, or even tell the doctors I wasn't asleep.". This testimony shows that a patient's first reaction is usually to move to alert medical staff of this terrifying situation. Unfortunately, during the majority of surgical procedures, the patient is curarized, which causes neuromuscular block and prevents any movement of the patient. The innovation proposed by this thesis is to detect AAGA reliably by analysing, in real-time, motor brain activity under general anesthesia. In theory, detection of movement intention is possible by analyzing EEG signals from the motor cortex via a brain-computer interface (BCI). Indeed, both a movement execution but also a simple movement intention are characterized by power variations (i.e., Event-related (de)-synchronization called ERD/ERS) in the EEG alpha and beta bands over the motor cortex. Electrical stimulation of the median nerve also induces changes in cortical activity which are visible in the EEG signal and similar to an intention of movement. Interestingly, when an intention to move a hand occurs at the same time as a median nerve stimulation, the ERD/ERS cortical signature is amplified and can be detected better by a BCI based on specific machine learning techniques. In order to design a BCI that would allow the detection of AAGA, this thesis is based on three disciplines (i.e. anesthesia, neurophysiology, computer science) and has three major objectives: (i) to study the effect of anaesthetics on the EEG signal of the motor cortex, (ii) to detect the patient's attempted movement without temporal markers using a BCI based on median nerve stimulation and (iii) to study motor brain activity in clinical conditions that will be close to intraoperative recovery

Full textThe measurement of the thermophysical properties of non-Newtonian fluids, particularly their thermal conductivity, is highly important for development of processes involving heat treatment (heating, coling, backing, etc. . . ). It also helps to plan the quality control of these products when their thermophysical properties are sufficiently dependent on their formulation. For the case of concentrated solid/liquid suspensions, the mass concentration, for example, is a fundamental quality parameter, which strongly influences not only the product's rheological properties, but also its economics value. The determination of the product's thermal conductivity, which is strongly dependent on concentration, could often an indirect control method of a continuous mixing operation, or, for example, a method to monitor the sedimentative stability. The author presents a needle-type thermal probe, based on the transient heat flow method (line-source technique), designed for the in situ measurement of the apparent thermal conductivity of aqueous solutions of water-soluble polymers and of concentrated solid/liquid suspensions. The thermal conductivity variations at 20°C, versus concentration of the aqueous solution, are given for three CMC and for one CARBOPOL, commercially available, given a large range of viscosity. The thermal conductivity variation versus temperature is also given. The suspension investigated is mixture of coal in water and polystyrene spheres in water. They consist in pseudo homogenous ùixture behaving as highly viscous non-Newtonian fluids

Full textSundaland is one of the most threatened biodiversity hotspots, experiencing a fast increase of threat levels during last decades. Covering Malayan Peninsula, Sumatra, Java and Borneo, this hotspot has one of the highest species richness and endemism for vertebrates in SEA, including freshwater fishes. This level of biodiversity has long attracted the attention of evolutionary biologists, particularly by considering effects of Sundaland complex geological history. This study addressed it by exploring time frame of vicariance and dispersal during diversity build-up of freshwater fish species in Sundaland. To support this, we first aimed to assess the match between distribution of molecular lineages from multiple taxa with palaeoriver boundaries using metadata analysis of existing molecular dataset with representative biological and spatial coverage in Southeast Asia (especially in Sundaland). Second, we focussed on estimating clades’ age and geographic distribution of Rasbora lineages in relation to the Pleistocene Palaeoriver Hypothesis by utilising newly generated empirical data for Rasborinae, a widespread and extremely diversified group of primary freshwater fishes in Sundaland. On both steps, we questioned: 1) if palaeorivers served as corridors of dispersal between islands during Pleistocene sea levels low stands; 2) if palaeoriver watersheds initiated allopatric divergence across their boundaries; and 3) if Pleistocene climatic fluctuation increased rates of species diversification. Overall, this study detected high level of cryptic diversity. Ancestral area reconstructions revealed that Sundaland freshwater fish lineages originated from Mainland Asia, and further colonised the region since Oligocene. This result validated the pre-Pleistocene settlement hypothesis. These lineages entered Sundaland mainly through North Sunda palaeoriver in contemporary Borneo and dispersed to other parts of Sundaland via long distance dispersal, often followed by in situ diversification. These results suggest Bornean part of North Sunda palaeoriver is the most likely centre of origin for Sundaland freshwater fishes. Contrary to the initial hypothesis, we found that although lowered sea level during glacial periods reconnected watersheds within palaeorivers, it did not necessarily open up inter-island dispersal channels for freshwater fishes. Corridors of savanna and seasonal forest ecosystems in the interior of Sundaland served as barrier to dispersal. Also, permeability of the physical boundaries of palaeoriver’s watersheds as well as geomorphological and habitat variabilities within palaeoriver created respectively gene flow between palaeorivers and allopatric speciation within palaeoriver. Moreover, although significant proportion of Sundaland freshwater fish lineages originated during Pleistocene, we found that Pleistocene dynamics did not affect diversification rate as sea level-dependent diversification models poorly account for species proliferation patterns for all clades excepting Channa. Besides, none of the taxa examined has declining diversification rates as suggested by diversity-dependent diversification (DDD) model. It is suggested then that global Pleistocene eustatic fluctuation and regional paleoriver dynamics are not sole drivers for Sundaland freshwater fish diversification, but only a part of abiotic aspects affecting it. Pleistocene Climatic Fluctuations likely interacted with other factors such as: landscape geomorphology, local ecosystem/habitat variability and life history traits of organisms
