Résumé : International audience
This paper provides a simple algorithm for writer identification of historical letters. The collected database is an original historical database, of 100 pages belonging to 25 people selected from a 500 letters database. In the article there is presented an article for a cauterization of the letters, because the system doesn't have the templates of the classes and doesn't know how many classes is in the database. The obtained result shows that automatic identification can help historical experts to segregate the documents, before they would analyze the text information.

Résumé : Antimicrobial peptides play a major role in innate immunity. The penaeidins, initially characterized from the shrimp Litopenaeus vannamei, are a family of antimicrobial peptides that appear to be expressed in all penaeid shrimps. As of recent, a large number of penaeid nucleotide sequences have been identified from a variety of penaeid shrimp species and these sequences currently reside in several databases under unique identifiers with no nomenclatural continuity. To facilitate research in this field and avoid potential confusion due to a diverse number of nomenclatural designations, we have made a systematic effort to collect, analyse, and classify all the penaeidin sequences available in every database. We have identified a common penaeidin signature and subsequently established a classification based on amino acid sequences. In order to clarify the naming process, we have introduced a 'penaeidin nomenclature' that can be applied to all extant and future penaeidins. A specialized database, PenBase, which is freely available at http://www.penbase.immunaqua.com, has been developed for the penaeidin family of antimicrobial peptides, to provide comprehensive information about their properties, diversity and nomenclature.

Résumé : Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - ). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.

Résumé : International audience
Background: Squamous cell carcinoma (SCC) is considered the most frequent skin cancer in black people. Its incidence is not known in the Afro-Caribbean population.Objective: To assess the incidence of SCC in Guadeloupe, the largest island of the Lesser Antilles (405 000 inhabitants, mostly black people of African and European descent). The second objective was to characterize clinical and histological patterns of SCC occurring in the Afro-Caribbean community.Methods: This retrospective study was conducted over an 11-year period (2000-2010). Data regarding 723 histological confirmed cases of SCC identified using the three Guadeloupean pathology laboratories computerized databases were retrieved from the records of 551 patients. Private practice dermatologists and general practitioners were contacted to obtain any missing data. Results: The annual age-adjusted incidence of SCC was 15 per 100.000 residents in Guadeloupe. In the Afro-Caribbean community, SCC had a greater size (i.e.: 2.8±2.8 cm versus 1.5±1.0 cm, p<0.001), was more often located on the anogenital area (i.e. :48/79-60.8% versus 14/320-4.4%, p<0.001) in association with an underlying dermatosis due to HPV infection (15/71- 21.1% versus 3/366, 0.8%, p<0.001) and led more frequently to metastasis (13/84-15.5% versus 10/366-2.7%, p<0.001) and/or fatal evolution (11/83-13.3% versus 7/365-1.9%, p<0.001). Conclusions: The results of this original study, which first estimated the incidence of SCC in West Indies, suggest that anogenital examination should be routinely performed in skin cancer screening of Afro-Caribbean people in order to detect the presence of SCC at an early stage.

Résumé : International audience
This paper presents an experimental investigation on stability and complexity of dynamic signatures. A technique based on multiple matching strategies using Dynamic Time Warping is considered to derive both stability and complexity information from dynamic signatures. The experimental results, carried out on signatures of the SUSIG database, highlight some interesting characteristics on handwritten signatures.

Résumé : International audience
Sedimentary rocks and detrital minerals sample large areas of the continental crust, and they are increasingly seen as a reliable archive for its global evolution. This study presents two approaches to model the growth of the continental crust through the sedimentary archive. The first builds on the variations in U-Pb, Hf and O isotopes in global databases of detrital zircons. We show that uncertainty in the Hf isotope composition of the mantle reservoir from which new crust separated, in the 176Lu/177Hf ratio of that new crust, and in the contribution in the databases of zircons that experienced ancient Pb loss(es), adds some uncertainty to the individual Hf model ages, but not to the overall shape of the calculated continental growth curves. The second approach is based on the variation of Nd isotopes in 645 worldwide fine-grained continental sedimentary rocks with different deposition ages, which requires a correction of the bias induced by preferential erosion of younger rocks through an erosion parameter referred to as K. This dimensionless parameter relates the proportions of younger to older source rocks in the sediment, to the proportions of younger to older source rocks present in the crust from which the sediment was derived. We suggest that a Hadean/Archaean value of K = 1 (i.e., no preferential erosion), and that post-Archaean values of K = 4–6, may be reasonable for the global Earth system. Models built on the detrital zircon and the fine-grained sediment records independently suggest that at least 65% of the present volume of continental crust was established by 3 Ga. The continental crust has been generated continuously, but with a marked decrease in the growth rate at ~ 3 Ga. The period from > 4 Ga to ~ 3 Ga is characterised by relatively high net rates of continental growth (2.9–3.4 km3 yr− 1 on average), which are similar to the rates at which new crust is generated (and destroyed) at the present time. Net growth rates are much lower since 3 Ga (0.6–0.9 km3 yr− 1 on average), which can be attributed to higher rates of destruction of continental crust. The change in slope in the continental growth curve at ~ 3 Ga is taken to indicate a global change in the way bulk crust was generated and preserved, and this change has been linked to the onset of subduction-driven plate tectonics. At least 100% of the present volume of the continental crust has been destroyed and recycled back into the mantle since ~ 3 Ga, and this time marks a transition in the average composition of new continental crust. Continental crust generated before 3 Ga was on average mafic, dense, relatively thin (< 20 km) and therefore different from the calc-alkaline andesitic crust that dominates the continental record today. Continental crust that formed after 3 Ga gradually became more intermediate in composition, buoyant and thicker. The increase in crustal thickness is accompanied by increasing rates of crustal reworking and increasing input of sediment to the ocean. These changes may have been accommodated by a change in lithospheric strength at around 3 Ga, as it became strong enough to support high-relief crust. This time period therefore indicates when significant volumes of continental crust started to become emergent and were available for erosion and weathering, thus impacting on the composition of the atmosphere and the oceans.

Résumé : International audience
We present a plant trait database covering autecology for rain forest trees of French Guiana. The database comprises more than thirty traits including autecology (e.g., habitat associations and reproductive phenology), wood structure (e.g., density and tension characteristics) and physiology at the whole plant (e.g., carbon and nitrogen isotopes) and leaf level (e.g., specific leaf area, photosynthetic capacity). The current database describes traits for about nine hundred species from three hundred genera in one hundred families. For more than sixty species, data on twelve morphological and ecophysiological traits are provided for individual plants under different environmental conditions and at different ontogenetic stages. The database is thus unique in permitting intraspecific analyses, such as the effects of ontogenetic stages or environmental conditions on trait values and their relationships.

Résumé : The brown shrimp Penaeus subtilis growth parameters has been studied by a lot of biologist since the fisheries of the three Guyana and Brazil has been created. The following through of the French Guyana’s fisheries had hallowed us to have an important database about shrimp boat lending. This atabase had permit us to fine the values used for predictive models helped by software like FISAT 2 in this case. This database had permit us to follow the evolution of the growth parameters along the fifteen last years. This study had given us different results which are interesting. First, the L∞ values used by the COPACO workshop (Isaac et al, 1992) are under evaluated and the K values aren’t. in a second time, the K values of the female brown shrimp are decreasing in a significant way since 1989, this case is not the male’s one. At last, we haven’t fond a link between meteorological variation in French Guyana (rainfall, river’s flow, sunshine) or biological data (biomass, density) and the K variations. A ecosystemic model feasibility study had been done for the French Guyana littoral. The data that are existing in the literature aren’t sufficient to build a model of this ecosystem. Future studies will perhaps provide the data that are missing to realize a first model
Les paramètres de croissance de la crevette Penaeus subtilis ont été étudiés par de nombreux auteurs depuis la création de la pêcherie sur le bouclier des Guyanes. Cependant le suivi permanent de cette pêcherie a permis d’avoir une base de données importante sur les débarquements des crevettiers et ainsi de chercher à affiner les estimations utilisées dans les modèles d’évaluation avec l’aide de logiciel prévus à cet effet comme FISAT 2 utilisé ici. Ces données peuvent permettre aussi de suivre l’évolution de ces paramètres au fil des années.Il ressort de cette étude plusieurs résultats intéressants. En premier lieu, les valeurs de L∞utilisées par le groupe de travail de la COPACO (Isaac et al, 1992) sont sous-évaluées et les valeurs de K ne le sont pas forcément. En second lieu, le K des femelles présente une tendance à la diminution sur les quinze dernières années (1989 – 2003), ce qui ne semble pas être le cas des mâles. Enfin, nous ne pouvons rattacher facilement les variations de K enregistrées à aucune donnée météorologique ne concernant que la Guyane (pluviosité, débit des fleuves, insolation), ni à certaines données biologiques (biomasse, densité). La faisabilité d’un modèle écosystémique du littoral a aussi été étudiée. Il en ressort que dans l’état actuel des connaissances sur l’écosystème du littoral guyanais la réalisation d’un modèle n’est pas possible. Mais des campagnes d’études à venir pourraient permettre de recueillir suffisamment de données pour pouvoir dresser un premier modèle.

Résumé : International audience
Cell proliferation is a hallmark of cancer and depends on complex signaling networks that are chiefly supported by protein kinase activities. Therapeutic strategies have been used to target specific kinases but new methods are required to identify combined targets and improve treatment. Here, we propose a small interfering RNA genetic screen and an integrative approach to identify kinase networks involved in the proliferation of cancer cells. The functional siRNA screen of 714 kinases in HeLa cells identified 91 kinases implicated in the regulation of cell growth, most of them never being reported in previous whole-genome siRNA screens. Based on gene ontology annotations, we have further discriminated between two classes of kinases that, when suppressed, result in alterations of the mitotic index and provoke cell-cycle arrest. Extinguished kinases that lead to a low mitotic index mostly include kinases implicated in cytosolic signaling. In contrast, extinguished kinases that result in a high mitotic index mostly include kinases implicated in cell division. By mapping hit kinases in the PhosphPOINT phosphoprotein database, we generated scale-free networks consisting of 449 and 661 protein-protein interactions for kinases from low MI and high MI groups, respectively. Further analyses of the kinase interactomes revealed specific modules such as FER- and CRKL-containing modules that connect three members of the epidermal growth factor receptor (EGFR) family, suggesting a tight control of the mitogenic EGF-dependent pathway. Based on experimental studies, we confirm the involvement of these two kinases in the regulation of tumor cell growth. Based on a combined approach of large kinome-wide siRNA screens and ontology annotations, our study identifies for the first time two kinase groups differentially implicated in the control of cell proliferation. We further demonstrate that integrative analysis of the kinase interactome provides key information which can be used to facilitate or optimize target design for new therapeutic strategies. The complete list of protein-protein interactions from the two functional kinase groups will provide a useful database for future investigations.

Résumé : International audience
Environmental resources (e.g., air quality, water quantity) are needed to understand fundamental questions such as global change. Such resources are often collected from sensors, including humans acting as sensors. Tools have emerged to manage such data in the form of time series and, in particular, the Sensor Observation Service (SOS) which offers a framework based on predefined relational database schema. Environmental observatories can be built using such frameworks, allowing to address specific key scientific questions by collecting and sharing large-scale environmental data. However, the strict schema of SOS database makes it difficult to integrate some data that cannot be directly mapped to the schema. Guidelines and best practices are offered in the literature in order to reuse standards from the Semantic Web but they do not cover all needs. In particular, they do not help to reflect the fact that a single environmental database can lead to several SOS models. Since being aware of these multiple possibilities is crucial for a better use of the observatories, we argue that some extensions of the existing works are required. In this paper, we thus propose an extension of existing vocabularies to achieve this goal. Our contribution is illustrated on the real case of the Lebanese-French O-LiFE environmental observatory.

Résumé : La tuberculose (TB), maladie infectieuse contagieuse, est causée par une mycobactérie appartenant au complexe Mycobacterium tuberculosis (MTBC). Malgré de nombreuses campagnes de vaccination par le BCG (Bacilles de Calmette et Guérin) et les traitements antituberculeux, on observe une réémergence de la maladie depuis les années 80. Ce bouleversement s’explique par la coïnfection avec le virus du VIH/SIDA, la désorganisation des systèmes de santé et par l’apparition des bactéries résistantes aux principaux antibiotiques antituberculeux. Dans ce contexte une meilleure connaissance des mouvements et de l’évolution des clones circulants du bacille tuberculeux permettrait de détecter plus rapidement et de façon plus pertinente l’émergence d’épidémies. Le contrôle et la surveillance de la maladie représentent des moyens essentiels pour lutter contre l’expansion mondiale de la tuberculose. C’est ainsi que l’unité de la Tuberculose et des Mycobactéries de l’Institut Pasteur de la Guadeloupe (IPG) a mis en place une base de données de profils génotypiques pour l’étude de l’épidémiologie globale de la tuberculose. Dans le cadre de cette thèse, nous décrirons les méthodes de bioinformatique qui ont été utilisées pour la gestion et l’exploitation de la 6ème version (SITVIT2) de cette base de données des génotypes pour mieux comprendre l’évolution et la dissémination mondiale du bacille tuberculeux. Cette base intègre aussi plusieurs marqueurs moléculaires tels que les MIRU-VNTRs (« mycobacterial interspersed repetitive units-variable number of tandem repeats ») et le Spoligotype43 servant à mieux décrire et identifier les familles de profils génotypiques du MTBC. La banque de données SITVIT2 ne cesse d’évoluer, et elle contient actuellement des informations épidémiologiques sur 111 635 isolats cliniques. Cette base de données est consultable en ligne à l’adresse suivante : http://www.pasteur-guadeloupe.fr:8081/SITVIT2/. Nous avons également réalisé une base de données nommée SITVITBovis qui est dédiée à la tuberculose bovine. Cette base de données sera accessible à l’adresse : http://www.pasteur-guadeloupe.fr:8081/SITVIT_Bovis/. Parallèlement au développement et à la gestion des bases de données, ce travail de thèse s’est appuyé sur plusieurs études épidémiologiques et phylogéographiques mettant en corrélation les données disponibles sur la résistance aux médicaments ou les caractéristiques démographiques (dont le sexe, l’âge, le statut VIH, et l’origine du patient). Notre initiative de recherche permet ainsi d’améliorer la caractérisation phylogénétique détaillée des lignées du MTBC, ainsi que l’épidémiologie des clones en circulation, afin d’élaborer une cartographie géographique des isolats cliniques prédominants pour les bacilles tuberculeux principalement impliqués dans la maladie, à l’échelle nationale, régionale et mondiale. La superposition ultérieure de ces cartes avec des données sociopolitiques, économiques et démographiques obtenues auprès de Systèmes d’information géographique (SIG) ont permis de dresser un portrait précis des disparités actuelles par pays ou sous-région. Cette thèse représente une importante collaboration avec plusieurs équipes de chercheurs travaillant également dans le domaine de l’épidémiologie moléculaire de la tuberculose. L’objectif à long terme de ce travail, est d’optimiser la structure de la base, et de pérenniser l’enrichissement de celle-ci (notamment par l’automatisation et la facilité de la saisie de données). Une représentation optimale et une meilleure accessibilité des données de la base conforteraient les efforts faits pour le contrôle et la surveillance de la TB dans monde.
Tuberculosis (TB) is a contagious infectious disease caused by mycobacteria belonging to the Mycobacterium tuberculosis complex (MTBC). Despite numerous campaigns of vaccination by the BCG (Bacillus Calmette-Guérin) vaccine, and TB treatments, there was a resurgence of the disease since the 80s. This disruption is due to coinfection with HIV/AIDS, disorganization of health systems and the emergence of bacteria resistant to anti-TB drugs. In this context, a better understanding of the movements and changes of circulating clones of tubercle bacilli would detect faster and more relevant emerging epidemics. The control and monitoring of the disease are essential means to fight against the worldwide spread of tuberculosis. Thus the TB and Mycobacteria unit of the Pasteur Institute of Guadeloupe (IPG) has developed a database of genotypic profiles for the study of global epidemiology of tuberculosis.In this thesis, we discuss the Bioinformatical methods that have been used for the management and development of the 6th version (SITVIT2) of this database of genotypes to better understand the evolution and global dissemination of the tubercle bacillus. The database also includes several molecular markers such as MIRU-VNTRs (mycobacterial interspersed repetitive units- variable number of tandem repeats) and Spoligotype43 allowing a better description and identification of the families of genotypic profiles of Mycobacterium tuberculosis complex. SITVIT2 database is constantly evolving, and it currently contains epidemiological information on 111,635 clinical isolates. This database is available online at the following address: http://www.pasteur-guadeloupe.fr:8081/SITVIT2/. We also developed a database named "SITVITBovis", which is dedicated to bovine tuberculosis. This database will be accessible at: http://www.pasteur-guadeloupe.fr:8081/SITVIT_Bovis/.Alongside the development and management of databases, this work was based on several epidemiological and phylogeographic studies correlating data on drug resistance or demographic characteristics (including sex, age, HIV status, and the origin of the patient). Our research initiative is thus focused to further improve in depth phylogenetic characterization of MTBC lineages, as well as the epidemiological analysis of circulating clones to generate evidence-based geographical mapping of predominant clinical isolates of tubercle bacilli causing the bulk of the disease both at country and regional level. Further superposition of these maps with socio-political, economical and demographical available through Geographic Information Systems (GIS) allows to have a precise view of prevailing disparities at the level of country or sub-region. This thesis represents an important collaboration with several researchers teams also working in the field of molecular epidemiology of tuberculosis.The long-term goal of this work is to further optimize the database structure, and sustain enriching it (including automation and ease of data entry). Optimum performance and accessibility of data in the database would reinforce efforts to control and surveillance of TB in the world.

Résumé : A database providing information on mosquito specimens (Arthropoda: Diptera: Culicidae) collected in French Guiana is presented. Field collections were initiated in 2013 under the auspices of the CEnter for the study of Biodiversity in Amazonia (CEBA: http://www.labexceba.fr/en/). This study is part of an ongoing process aiming to understand the distribution of mosquitoes, including vector species, across French Guiana. Occurrences are recorded after each collecting trip in a database managed by the laboratory Evolution et Diversité Biologique (EDB), Toulouse, France. The dataset is updated monthly and is available online. Voucher specimens and their associated DNA are stored at the laboratory Ecologie des Forêts de Guyane (Ecofog), Kourou, French Guiana. The latest version of the dataset is accessible through EDB’s Integrated Publication Toolkit at http://130.120.204.55:8080/ipt/resource.do?r=mosquitoessur french_guiana or through the Global Biodiversity Information Facility data portal at http://www.gbif.org/dataset/5a8aa2ad-261c-4f61-a98e-26dd752fe1c5 It can also be viewed through the Guyanensis platform at http://guyanensis.ups-tlse.fr

Résumé : International audience
Marine protist diversity inventories have largely focused on planktonic environments, while benthic protists have received relatively little attention. We therefore hypothesize that current diversity surveys have only skimmed the surface of protist diversity in marine sediments, which may harbor greater diversity than planktonic environments. We tested this by analyzing sequences of the hypervariable V4 18S rRNA from benthic and planktonic protist communities sampled in European coastal regions. Despite a similar number of OTUs in both realms, richness estimations indicated that we recovered at least 70% of the diversity in planktonic protist communities, but only 33% in benthic communities. There was also little overlap of OTUs between planktonic and benthic communities, as well as between separate benthic communities. We argue that these patterns reflect the heterogeneity and diversity of benthic habitats. A comparison of all OTUs against the Protist Ribosomal Reference database showed that a higher proportion of benthic than planktonic protist diversity is missing from public databases; similar results were obtained by comparing all OTUs against environmental references from NCBI's Short Read Archive. We suggest that the benthic realm may therefore be the world's largest reservoir of marine protist diversity, with most taxa at present undescribed.

Résumé : The Biocean database was designed to collate the extremely large volume of data collected from different deep-sea ecosystem studies conducted by Ifremer's department of 'Environnement Profond' (Deep-Sea Environment). This database comes in a 6-application package: 2 of them are used on research vessels to collect operational data, whereas the others are used to link with a core database back on land. The latter are used to: (1) manage taxonomic nomenclature, (2) monitor the identification of faunal collections, (3) fill in chemical analyses results or measurement data files and (4) add or extract data from the database. Biocean was designed to facilitate ecosystem studies in the deep sea. It represents an important new resource for deep-sea ecologists and will have wide applications in biogeography and biodiversity studies at Ifremer, but also for the international community, as faunal data are linked to the Census of Marine Life information system OBIS (Ocean Biogeographic Information System). Biogeographical analyses of Biocean data recovered through the OBIS portal evidence an evolution in the deep-sea sampling strategies more focused in limited areas and is intended to reveal ecosystems functioning.
