Full textThe group 1 Remorin (REM) proteins are plant-specific oligomeric proteins that have been reported to localize to the plasma membrane despite their overall hydrophilic nature. There is evidence that the REM protein phosphorylation is potentially implicated in the early signaling and defense. Benschop et al. (2007) detected the AtREM1.3 (Arabidopsis thaliana group 1b of REM protein family) to be phosphorylated in response to treatment with the general elicitor flg22, while the Widjaja et al. (2008) suggested that the phosphorylation of AtREM1.2 is potentially implicated in early signaling upon infection with Pseudomonas syringae. The precise exact function of the group 1 REM protein phosphorylation remains unknown. Previous work in the laboratory showed that Potato virus X (PVX) movement is inversely correlated to potato StREM1.3 accumulation and that StREM1.3 can physically interacts with the movement protein TRIPLE GENE BLOCK PROTEIN 1 (TGBp1) from PVX (Raffaele et al., 2009). In this work, we studied the mechanism underlying the REM-TGBp1 interactions and we tried to characterise biochemically the kinase that phosphorylate REM. The physiological consequences of TGBp1/ StREM1.3 interaction and REM phosphorylation in terms of virus spreading, post-transcriptional gene silencing, plasmodesmata gating, kinase activation were also investigated

Full textWe have developed a study focused on the viral propagation of the lambda bacteriophage. With the purpose of a detailed characterization of the dynamics of the spread of infection during the formation of plaques, we have constructed a bacteriophage lambda carrying a fluorescent fusion between the minor protein of the capsid GpD and the Enhanced Yellow Fluorescent Protein (EYFP). The next step has been to perform the preliminary characterisation of the properties of this new fluorescent virus including measurements of its diffusion coefficient on a plaque using the technique called FRAPP. Subsequently we have measured the dynamic of the phage population profiles in time within the plaque using time-lapse videomicroscopy. Supplementary experiments have been done in order to characterize the bacterial growth in Petri dishes on an agar substrate. The results have been compared to previous experiments and theoretical works performed in order to describe the propagation of the T7 bacteriophage. Finally, we have performed complementary numerical simulations that are in qualitative agreement with the experimental results

Full textIn this thesis, we study two applications of stochastic processes in internet marketing. The first chapter focuses on internet user scoring for real-time bidding. This problem consists in finding the probability for a given user to perform an action of interest, called conversion, in the next few days. We show that Hawkes processes are well suited for modelizing this phenomena but that state-of-the-art algorithms are not applicable to the size of datasets involved. We therefore develop two new algorithms able to perform nonparametric multivariate Hawkes process inference orders of magnitude faster than previous methods. We show empirically that the first one outperforms state-of-the-art competitors, and the second one scales to very large datasets while keeping very high prediction power. The resulting algorithms have been implemented with very good performances for several years in 1000mercis, a pioneering marketing agency being the industrial partner of this CIFRE PhD, where they became an important business asset. The second chapter focuses on diffusion processes graphs, an important tool for modelizing the spread of a viral marketing operation over social networks. We derive the first theoretical bounds for the total number of nodes reached by a contagion for general graphs and diffusion dynamics, and show the existence of two well distinct regimes: the sub-critical one where at most $O(sqrt{n})$ nodes are infected, where $n$ is the size of the network, and the super-critical one where $O(n)$ nodes can be infected. We also study the behavior wrt to the observation time $T$ and reveals the existence of critical times under which a long-term super-critical diffusion process behaves sub-critically. Finally, we extend our works to different application fields, and improve state-of-the-art results in percolation and epidemiology

Full textIntroduced into the environment through point and diffuse sources, enteric viruses and bacteriophages can be spread in watercourses via various dissemination routes. Detected in both surface water and river sediment, these viral particles remain inert in environmental water. Their spread is governed by many interactions that they have with their direct environment. Moreover, viral contamination of water resources is closely related to hydro-climatological variations. Despite the important knowledge already reported on this subject, many grey areas remain about the variables and factors controlling the in situ behavior of viral particles in environmental water. The aim of this study was therefore to define the transport and fate of F-specific RNA bacteriophages in a river according to their intrinsic characteristics and hydro-climatological conditions. The application of innovative strategies and methodologies from the hydrological science domain, such as the use of the residence time of the river water mass or high frequency automatic sampling, allowed studying the in situ behavior of F-specific RNA bacteriophages. The influence of environmental factors, especially water temperature and flow rate, has been demonstrated to have an impact on the in situ propagation and survival of infectious viral particles in the water column. Furthermore, the spatial distribution of infectious F-specific RNA bacteriophages was underlined in sediments. The accurate characterization of sediment and the study of the attachment capacity of the four genogroups explained this specific distribution. Finally, transfers of viral particles between the water column and sediment was highlighted and appeared to be highly dependent on hydro-climatological conditions. Besides the gained knowledge of the dynamics of F-specific RNA bacteriophages, the sources and origins of viral pollution of streams during rain and flood events were elucidated. This work helps completing the jigsaw puzzle on presence and transmission of F-specific RNA bacteriophages in river systems. The novel experimental approach further enhances human health-dependent viral risk evaluation linked to water resource utilization and management

The participation of the health sector in sanitation must be guided to the universality of the service, surnaunting technical, political and managerial enumbrances which have brought difficulties to extended the benefits to the population who live in rural areas, small counties and localities. Thus, we verify that the basic social rights of the vulnerable and abandonned groups donât consolidate, becoming for this reason in a picture of social inequalities, poverty and indigence. When we speak about the relation between health and sanitation is essential to include it in the spoken subject of the relation health and environment. The first confirmation, in this aspect, show preoccupations about the relation health-sanitation. They were certainly in the root of the actual sight health-environment. The questions about sanitation were almost exclusive, especially before the Industrial Revolution. They were that characterized historically the environment of the health. This correlation between basic sanitation and health represented here by the Tax of Incidence of tre sicknesses brought by the veiculation of the water, the Viral Hepatite, was studied by the counties of the State of CearÃ, as a way to measure the influence of the operation of the CAGECE to improve the peopleâs health conditions in relation to the counties that werenât operate by this company.

Full textThe aggregation of α-synuclein (α-syn) is central in the pathological process observed in Parkinson’s disease or multiple system atrophy. Β synuclein (β-syn) shares some similarities with α-syn but may have a neuroprotective effect by inhibiting the aggregation of α-syn. The goal of this thesis was to develop and to test a therapeutical strategy potentially able to inhibit the aggregation of α-syn by expressing human β-syn using adeno-associated vectors (AAV). First, we characterized a model of synucleinopathy, the M83 transgenic mouse. These mice express the human A53T mutated α-syn and develop a severe disease associated with the aggregation of α-syn. Our results confirm the ability of the aggregation of α-syn to spread through the central nervous system following a peripheral injection of aggregates of α-syn. Furthermore, they show that the accumulation of pathological α-syn in sick M83 mice depends on the inoculum used to accelerate their disease and the expression level of human A53T mutated α-syn in these mice. Gene therapy trials realized in the M83 model suggest that, regardless the strategy used to inject AAV vector, β syn did not have a protective effect against the aggregation of α-syn. A lasting expression of the human β-syn protein was however detected in sick M83 mice injected with AAV vector carrying human β-syn gene. Nevertheless, β-syn could have aggregated in our specific experimental conditions, as this has already been described, which might explain the absence of protective effect detected

Full textDuring a lytic infection, Herpes Simplex Virus type 1 (HSV-1) must go through multiple steps of fusion to replicate and propagate properly. For this purpose, the virus has evolved consequently by taking advantage of the cellular machinery using host factors and proteins. In the literature, processes underlying HSV-1’s entry have been extensively elucidated. However, it remains unclear how newly synthesized viral particles egress from the host cell, and what cellular factors are implicated in this process. Results published by our laboratory suggest that the cellular protein, Extended Synaptotagmin 1 (E-Syt1), has a negative and global impact on the viral propagation when down regulated by RNA interference. Consequently, this study aims to confirm and deepen our understanding of E-Syt1’s role on HSV-1, particularly during viral egress. Since activation of E-Syt1 is linked to the increase in cytoplasmic calcium concentration, we also investigated calcium involvement during later stages of viral propagation. Interestingly, overexpression of E-Syt1 had no measurable effect on HSV-1 propagation whereas calcium has a dual effect on viral propagation. While early calcium sequestering (4 and 6 hours post-infection) using chelators represses viral egress, no significant effect was detected when chelators were added at later time points (12 and 16 hours post-infection). Our results give interesting insights on how HSV-1 relies on intracellular calcium homeostasis to properly mediate viral egress. These results may lead to the discovery of new mechanisms or cellular proteins that are regulated by calcium and hijacked by HSV-1 during lytic replication.
