Puesto que el estudio de los procesos puntuales espacio-temporales no ha sido muy exhaustivo en la literatura, hemos hecho un artículo de resumen. Introducimos un test de permutación para grupos de patrones puntuales espacio-temporales motivado por las ubicaciones de ocurrencias de tornados en EE.UU. durante 36 años. Hemos desarrollado algunas técnicas como la estimación de la intensidad de primer-orden sin suponer separabilidad, lo que permite un tratamiento más realista del fenómeno climático en sí mismo a través del nuevo test.Finalmente, hemos desarrollado algunas técnicas para el análisis de la varianza de experimentos de dos factores en presencia de réplicas cuando las observaciones son patrones puntuales espaciales. Esta metodología está motivada por un experimento de ingeniería de minerales. Desarrollamos algunos estadísticos adecuados para probar la influencia de los factores y su posible interacción.

Повний текст джерелаContexte: L'organisation mondiale de la santé (OMS) estimait à 12 millions le nombre de nouveaux cas de syphilis en 2006. Les pays en développement sont souvent confrontés à des lacunes en termes de dépistage adéquat, attribuables aux services de laboratoire limités. Pour les pays développés, ce sont les populations marginalisées qui souffrent souvent d'un accès limité aux services de santé. Dans ce contexte d'inégalités des systèmes de santé, et bien qu'on ait déjà démontré que les tests au point d'intervention représentaient une ressource de très grande valeur, leur précision diagnostique et l'analyse de résultats d'implantation (IRO) doivent d'abord être établis, afin de justifier leur utilisation.Méthodes: Nous avons effectué une recherche d'articles traitant de l'évaluation des tests au point d'intervention pour la syphilis dans six bases de données électroniques, du 1980 au 2010. Deux évaluateurs ont analysé les données. Des sous-groupes ont été créés en fonction des types de tests, échantillons et étalons de référence. Nous avons généré des tests de sensibilité et spécificité mises en commun, à l'aide de courbes Hierarchical Summary Receiver Operating Characteristic(HSROC), et avons ajusté les valeurs pour tenir compte des étalons de référence imparfaits. Nous avons aussi synthétisé de façon narrative les analyses de résultats d'implantation (IROs).Résultats: Après avoir sommairement évalué 64 articles complets, 30 (47%) articles ont été inclus dans la méta-analyse d'exactitude diagnostique, et 24 (38%) articles ont été inclus dans l'examen narratif des analyses de résultats d'implantation (IROs). Quatre tests ont été évalués à travers l'ensemble des études : Determine® (29%), Bioline® (18%), Syphicheck® (15%), et Visitect® (14%). Après ajustement pour tenir compte de l'imperfection des étalons de référence, dans des échantillons de sérum, en utilisant un étalon de référence spécifique pour le TP (treponema pallidum) (par exemple, le TPPA), le test Bioline® s'est avéré avoir le test de sensibilité mise en commun le plus élevé, soit 99,67% (95% intervalle crédible 97,65 - 100), suivi de Determine® avec 99,14% (96,93-100), Visitect® avec 98,18% (93,53-100) et Syphicheck® avec 88,46% (73,54-99.87). Syphicheck® a obtenue test de spécificité mise en commun le plus élevé, soit 99,98% (99,64-100), suivi de Visitect® avec 99,89% (99,19-100), Determine® avec 99,68% (98,70-100) et Bioline® avec 99,56% (98,55-100). Dans des échantillons sanguins complets, Bioline® a obtenu le test de sensibilité mise en commun le plus élevé, soit 91,47% (87,06-96,12), suivi de Determine® avec 89,49% (79,88-98,15), Visitect® avec 82,93% (94,50-100) et Syphicheck® avec 81,99% (71,84-91,99). Determine® a obtenu le test de spécificité mise en commun le plus élevé, soit 99,91% (99,44 - 100), suivi de Visitect® avec 99,87% (99,58-100), Syphicheck® avec 99,81% (99,46-100), et Bioline® avec 99,61% (99,04 -100). L'acceptabilité, la faisabilité et l'impact des tests au point d'intervention ont aussi été démontrés dans plusieurs études. La préférence n'a pas été suffisamment bien établie, et les évaluations économiques étaient trop hétérogènes pour être concluantes.Conclusion: Bioline® et Determine® ont obtenu respectivement les tests de sensibilité et spécificité mises en commun les plus élevés. Les tests plus élevés dans les échantillons de sérum suggèrent fortement, lorsque possible, l'utilisation de ces tests dans ce contexte, plutôt qu'avec des échantillons sanguins complets. En comparant nos résultats aux stratégies de tests actuellement en application, on constate qu'il serait approprié de remplacer les tests sérologiques avec des tests au point d'intervention, même lorsque l'accès à un laboratoire ou à du personnel adéquatement formé n'est pas une problématique. De plus amples recherches sur les analyses de résultats d'implantation sont nécessaires, et un cadre d'étude pour l'évaluation de ces résultats est urgemment requis.

Повний текст джерелаAnimal behavior has become a fundamental tool in translational neuroscience area and is useful for studying physiological mechanisms underlying neurological diseases and also for understanding the functional modifications induced by genetic manipulation or chemical treatment. The experiment of new treatments requires animal models miming the human pathology. In Humans batteries of cognitive and motor tests are used to qualify and quantify the impairment due to neurodegenerative disease as Alzheimer's disease and Parkinson’s disease. The aim of this work is to promote Microcebus murinus as a model of age related neurodegenerative pathologies. The grey mouse lemur, a small prosimian primate, phylogenetically close to Human, presents specific characteristics susceptible to provide important information on the validity and efficacy of new. The validation of a model requires the use of behavioral tests to discriminate neurodegenerative impairment. A set of behavioral tests were worked out to evaluate learning memory and motor functions. Healthy animals were evaluated and allowed to define protocols species specific. These protocols were then applied on animals treated to induce pathology such as Parkinson or Alzheimer in order to detect cognitive or motor impairments

Dysfunctions of ocular motor and binocular vision are some of the most commonly observed problems in patients with severe traumatic brain injury. Secondarily, subjective complaints of compromised vision and ocular motor functions are also sometimes reported in mild traumatic brain injuries (mTBI). Simple ocular/vision assessments such as near point of convergence (NPC), the King-Devick Test (KDT), and stereoacuity can be performed to identify and assess these deficits, but their diagnostic accuracy has yet to be thoroughly investigated. The purpose of this study was to determine if differences exist in NPC, KDT, and stereoacuity test scores between concussed and control athletes, and to determine the diagnostic accuracy of these tests. A multicenter control group design was utilized. The independent variable was group (control vs. concussed). The dependent variables were the ocular test scores from the NPC, KDT, and stereoacuity tests. Participants were recruited from several collegiate athletic programs. In total 34 healthy, non-concussed controls (21 male, 13 female) aged 19 + 1.5 years and 19 concussions (11 male, 8 female) aged 20.42 + 1.5 years participated in the study. A concussion was operationally defined as a complex pathophysiological process affecting the brain, induced by biomechanical forces, that was diagnosed by a health care professional through the use of signs and symptoms scales, balance and neurocognitive testing. Data were analyzed using descriptive and inferential statistics. T-tests and chi-squares were performed to ensure there were no significant differences between groups on specific demographic or relevant prognostic variables (sport, sex, and concussion history). T-tests were employed to identify significant differences between groups on ocular test scores. Then clinical and statistical cutoffs for all three tests were determined. Based off of these cutoffs sensitivity, specificity, and likelihood ratios were determined for each assessment. Furthermore, receiver operating characteristic (ROC) curves were calculated to help determine the diagnostic accuracy of these assessments. The alpha level was set at p < .05 and the SPSS for Windows, Version 21.0, statistical program (IBM, Inc., Armonk, NY) was used for all data analysis. Significant differences were found between groups for all three ocular assessments. NPC demonstrated a statistical cutoff of 5.5 cm, which provided a sensitivity of 79% and specificity of 76% and an AUC of 0.827. For the KDT, a statistical cutoff time of 49.5s demonstrated a sensitivity of 58% and specificity of 72% with an AUC of 0.658. Lastly, for stereoacuity a statistical cutoff point of 28.50 arc sec was found which produced a sensitivity of 65% and specificity of 54% with a maximum AUC of 0.706. All three tests demonstrated their potential to positively contribute to the diagnosis of a concussion.

Повний текст джерелаObjetivo. El objetivo de esta tesis fue evaluar la validez de dos tests antigénicos rápidos (TAR) inmunocromatográficos en pacientes con alta sospecha de presentar faringitis por estreptococo β-hemolítico del grupo A (EBHGA). Además, se evaluó la repetición del TAR en pacientes con una prueba previamente negativa y se determinó también la asociación de los niveles de proteína C reactiva (PCR) con la etiología de la faringitis en cuatro subestudios observacionales prospectivos realizados entre 2007 y 2012 en un centro de salud. Métodos. Se incluyeron a pacientes de 14 años o más con clínica de faringitis aguda y al menos dos criterios de Centor. Todos los pacientes fueron sometidos al menos un frotis faringoamigdalar para cultivo microbiológico. Se analizaron dos TAR y el aparato de PCR usado fue el QuickRead/Go. Resultados. Se estudiaron un total de 686 pacientes. La prevalencia de EBHGA varió entre el 22% y el 24,8%. La prevalencia de estreptococo del grupo C varió entre el 8,8% y el 15,8%. La sensibilidad de la prueba de OSOM Strep A fue del 95%, con una especificidad del 93%, un valor predictivo positivo del 79,2% y un valor predictivo negativo del 98,5%. Estos resultados fueron 96,4%, 91,6%, 79,1% y 98,7%, respectivamente, con la repetición del TAR en aquellos pacientes con un primer resultado negativo. Los resultados con el uso de Analyz-Strep A fueron 93,6%, 93%, 88%, y 96,4%. Las concentraciones más altas de PCR correspondieron a los pacientes que presentaban infección por el estreptococo del grupo C con un valor medio de 56,3 mg/l. Conclusiones. Los principales resultados de estos estudios muestran la utilidad de una determinación única de un TAR, sin que sea necesario repetir otro TAR en los resultados negativos. Este estudio también muestra que la PCR no es útil para distinguir los pacientes con infección por EBHGA.
Objective. The aim of this thesis was to evaluate the validity of two immunochromotographic rapid antigen detection tests (RADT) in patients highly suspected of presenting pharyngitis by group A β-haemolytic streptococci (GABHS). In addition, the repetition of the RADT in patients with a previously negative test was also evaluated, and the association of C-reactive protein (CRP) levels with aetiology of pharyngitis was also determined in four prospective observational substudies carried out from 2007 to 2012 carried out in a primary care centre. Methods. Patients aged 14 or older with acute pharyngitis and at least two Centor criteria were consecutively recruited. All the patients underwent at least a pharyngotonsillar swab for microbiological culture. Two different RADTs were used and the CRP rapid test used was the QuickRead/Go device. Results. A total of 686 patients were studied. The prevalence of GABHS ranged from 22% to 24.8%. The prevalence of group C streptococcus ranged from 8.8% to 15.8%. The sensitivity of the OSOM Strep A test among patients was 95%, with a specificity of 93%, a positive predictive value of 79.2%, and a negative predictive value of 98.5%. These results were 96.4%, 91.6%, 79.1% and 98.7%, respectively, with the repetition of the RADT in patients with a first negative RADT result. These results were 93.6%, 93%, 88%, and 96.4% with the use of Analyz-Strep A Rapid test. The highest CRP concentrations were observed among patients with group C streptococcal infection with a mean value of 56.3 mg/l. Conclusions. The main result of these studies shows the usefulness of a single RADT determination for the diagnosis of GABHS infection with the repetition of RADT in those with a previous negative result being unnecessary. This study also shows that CRP is not useful for distinguishing patients with GABHS infection.

Повний текст джерелаEl Hormigón de Muy Alto Rendimiento (HMAR) combina los últimos avances tecnológicos en hormigón y se erige como un material prometedor para el futuro. El HMAR ha demostrado su gran capacidad para adaptarse a las cada vez más exigentes demandas sociales y medioambientales. Con un gran abanico de posibilidades en su dosificación para conseguir las propiedades mecánicas deseadas, el HMAR es un material lleno de posibilidades aún sin explorar y sin explotar. Los ingenieros tienen la responsabilidad de esta tarea. Sin embargo, es justo reconocer que no se trata de una tarea fácil y que requiere de un desarrollo previo de códigos de diseño adecuados y ampliamente aceptados por parte de la comunidad científica. La aparición de nuevas tecnologías, el mayor conocimiento sobre la aportación de las fibras así como su industrialización y bajada de precios, las mayores preocupaciones sobre la durabilidad estructural, incremento de la vida útil o la reducción de los costes de mantenimiento, entre otros factores, han derivado en el desarrollo de nuevas tipologías de hormigones cuyo comportamiento mecánico difiere de manera sustancial de los tradicionales hormigones con fibras. Es por ello que tanto la readaptación de las metodologías de caracterización como las metodologías de diseño deben ser reformuladas. Y esto debe hacerse de manera no disruptiva, es decir, manteniendo la línea de los hitos alcanzados en los hormigones con fibras convencionales de manera que queden integrados en metodologías de caracterización y de diseño que los engloben, porque al fin y al cabo, y aunque con nuevas y mejores propiedades mecánicas, los nuevos hormigones siguen siendo hormigones. Así debe ser entendido y así debe quedar reflejado en las nuevas normativas. El presente trabajo se centra en uno de esos nuevos materiales desarrollados con el avance de las nuevas tecnologías como es el HMAR. En especial, este documento se centra en ese aspecto tan fundamental para el desarrollo de nuevos hormigones como es la caracterización mecánica y la tipificación. Este trabajo incluye una revisión del comportamiento mecánico uniaxial a tracción del hormigón y de su evolución con la aparición de las diferentes tecnologías. Además, se revisan y se ponen en cuestión los sistemas tradicionales de caracterización, así como los nuevos sistemas desarrollados en los últimos años para su empleo específico en el HMAR. A lo largo del documento se desarrollan diferentes metodologías para la obtención del comportamiento constitutivo a tracción del HMAR, así como la propuesta de una metdología simplificada de caracterización especialmente diseñada para ser incluida en una norma, todas ellas debidamente validadas. Estas metodologías son de aplicación específica a los resultados experimentales obtenidos mediante un ensayo a cuatro puntos sin entalla, cuya propuesta de estandarización para el HMAR ha sido también desarrollada. Finalmente, se presenta una propuesta de tipificación de acuerdo a los parámetros más relevantes del comportamiento a tracción del HMAR que son necesarios para el diseño y que pueden ser directamente obtenidos del ensayo de caracterización propuesto. Esta clasificación engloba a la clasificación existente para el hormigón armado convencional y los actuales hormigones con fibras, de manera que se presenta la actual definición de hormigón con fibras como un caso particular de estos nuevos hormigones, respetando al máximo la evolución de este material y aunando los logros conseguidos por la comunidad científica.
Dins de les combinacions de les tecnologies més recents en el formigó, el formigó de molt alt rendiment (UHPFRC) sorgeix com un material prometedor per al futur pròxim. L'UHPFRC ha demostrat poder ser un formigó flexible per adaptar-se a les sempre canviants demandes socials i mediambientals. Amb una gran flexibilitat en la seua composició i les seues propietats mecàniques, l`UHPFRC està ple de possibilitats de ser explorades i explotades. Els enginyers han de prendre la responsabilitat d'aquesta tasca. No obstant això, és just reconèixer que això no serà fàcil i requerirà el desenvolupament de normes de disseny fiables i àmpliament acceptades per la comunitat científica. Hi ha una gran preocupació al voltant de la durabilitat, la vida útil de les estructures i la reducció del cost de manteniment, juntament amb el desenvolupament de noves tecnologies de formigó, un millor coneixement de l'efecte de la fibra i un enorme creixement en la indústria de la fibra acompanyat per la reducció del preu de la fibra, han conduït, entre altres factors, al desenvolupament de nous tipus de formigons, el comportament mecànic dels quals es diferencia substancialment dels formigons reforçats amb fibres convencionals. És per això que les metodologies de caracterització actuals i les normes de disseny han de ser revisades i ajustades a aquests nous materials. No obstant això, la revisió del codis de disseny no pot prescindir de les antigues fites aconseguides gràcies a dècades de treball dur. S'ha d'oferir una visió integrada en la qual els nous tipus de formigons integren els ja existents en un grup més ampli, ja que, al cap i la fi i malgrat tenir propietats noves i millorades, els nous tipus de formigons són encara un tipus de formigó. Així es com s'hauria d'entendre i reflectir-se en els nous codis i normes. El treball presentat en aquest document es centra en un d'aquests materials que s'han desenvolupat recentment i que abasta les principals tecnologies avançades en el formigó: el Formigó de Molt Alt Rendiment Reforçat amb Fibres (UHPFRC). Aquest treball se centra específicament en els requisits fonamentals per al desenvolupament i l'ús generalitzat d'aquest, com ara la caracterització i classificació del comportament constitutiu a tracció. Aquest treball inclou una revisió profunda del comportament a tracció uniaxial del formigó i els seus canvis al temps que la tecnologia de les fibres ha evolucionat. A més, els mètodes tradicionals estàndard de caracterització, així com els recentment desenvolupats per al seu ús específic en l'UHPFRC són revisats i qüestionats. Al llarg del document, es mostra el desenvolupament de diferents metodologies per a determinar el comportament constitutiu a tracció uniaxial de l'UHPFRC, juntament amb una proposta de caracterització simplificada especialment desenvolupada per poder ser inclosa en normativa. Totes les metodologies desenvolupades presentades en aquest document han estat comprovades i validades. Aquests mètodes estan dissenyats específicament per a la seva aplicació en els resultats experimentals obtinguts a partir d'un tipus especial d'assaig de flexió a quatre punts, a més també s'inclou una proposta d'estandardització per a l'UHPFRC. Finalment, es presenta una proposta de classificació en funció dels paràmetres més rellevants del comportament a tracció de l'UHPFRC que són necessaris per al disseny i que es poden obtindre directament del mètode d'assaig estàndard suggerit per a la caracterització de l'UHPFRC. La classificació proposada té amb compte la classificació existent per al formigó armat convencional i el reforçat amb fibres. En ella, tant el formigó en massa com el formigó reforçat amb fibres es presenten com un cas particular d'una resposta constitutiva a tracció més general per al formigó. La metodologia estàndard i la classificació proposada estan d'acord amb l'evolució de formigó i unifica l

Повний текст джерелаCyanobacteria are ubiquitous microorganisms that present a worldwide concern to public health authorities because of the toxicity of the cyanotoxins they produce. Some cyanotoxins are hepatotoxins such as microcystins (MCs). At least 200 variants of MCs have been identified till today. In our study, we focus on MC-LR, a monocyclic heptapeptide (cyclo-(D-Ala-L-Leu-D-erythro-β-methylAsp-L-Arg-ADDA-D-Glu-N-methyldehydro-Ala), since it is the most frequently detected and one of the most toxic. In our study, we are interested in developing a fast, sensitive and reliable method to detect MCs. The project aims to develop an alternative pollution detection method that would be better suited to field measurements than the physicochemical methods currently available. The originality of this project lies in the use of two different approaches to select a panel of antibodies suitable for the development of immunodetection tests. The first one is based on the hybridoma technology for the production of monoclonal antibodies. The second one is based on phage display technique to select antibody fragments that are specific to MC-LR from a library of approximately 109 phages, expressing on the surface scFv fragments (Shahsavarian et al., 2014). Two monoclonal antibodies were selected using the first approach, and their specificity was evaluated using ELISA technique. Along with three scFvs selected from phage display approach. An additional scFv was added to this list: 3A8, selected from a previous study (McElhiney et al., 2002) and also specific to MC-LR. The scFvs were cloned into an expression vector in order to get each clone in its scFv soluble form. Then, their specificity to MC-LR was evaluated using ELISA technique and Surface plasmon resonance. The results show a potential specificity to MC-LR. Nevertheless, these results are not very reproducible and call into question the refolding protocol used. A thorough work on this protocol optimization would be necessary, in order to find the key parameters that control the loss or gain of their functionality

Повний текст джерелаExtendemos los estadísticos tipo M para una raíz unitaria analizados por Perron y Ng (1996) y Ng y Perron (2001) al caso donde se permite que el cambio en la función de tendencia ocurra en un punto desconocido. Estos estadísticos (MGLS) adoptan el enfoque GLS para eliminar la tendencia desarrollado por Elliott et al. (1996) (ERS) siguiendo los resultados de Dufour y King (1991). Siguiendo a Perron (1989), consideramos dos modelos: uno que permite un cambio en la pendiente y otro que permite tanto un cambio en el intercepto como en la pendiente. Derivamos las distribuciones asintóticas así como el estadístico óptimo factible en un punto de la hipótesis alternativa (PT GLS) sugerido por ERS. También computamos el parámetro de no centralidad utilizado por el enfoque GLS local a la unidad con el fin de eliminar la tendencia que permite que el estadístico PT GLS tenga 50% de potencia asintótica en ese valor. Asimismo, se han tabulado los valores críticos asintóticos de los estadísticos. Mostramos que los estadísticos MGLS y PT GLS tienen una función de potencia asintótica cercana a la envolvente de potencia. Un estudio de simulación analiza el tamaño y potencia en muestras finitas bajo varios métodos para seleccionar la truncación para estimar la densidad espectral autorregresiva. Finalmente, también se presenta una aplicación empírica.

Повний текст джерелаThe chronic toxicity study of substances based on the intrinsic rate of population increase require the knowledge of survival and fecundity probabilities of the tests organisms. The chronic toxicity test application using Brachydanio rerio had been performed with three substances frequently meeting in waters (chrome, cadmium and atrazine) and had been conceived in two steps: - a life cycle test lasting 130 days post fertilisation for the determination of survival, growth and maturity ages, - a partial life cycle test for the reproduction study. We have compared the different development stage sensitivity and compared the sensitivity of the different tests methods: those based on the measure of intrinsic rate of population increase with those which also permit to assess the chronic toxicity: 15-days ELS tests and tests based on the reproduction. Reproduction appeared to be the most sensitive endpoint, the sensitivity factors determined between the early life stage and reproduction are equal to 4,7 to 11,7 with the three substances studies. Thus, the 15-days ELS tests appeared as no good predictors of effect on the complete life cycle on fish. However, for the ELS test realisation, our study shows that a test duration of 15 days is acceptable because the observed effects occurred within this duration. The toxicity test based on the intrinsic rate of population increase is a good method which provides an ecological relevant way but which present a bad cost-effective factor compared with ELS tests or reproduction tests

Повний текст джерелаHuman immunodeficiency virus-1 (HIV-1) is primarily transmitted sexually through mucosal surfaces, indicating that protection at mucosal sites may be crucial in prevention and in the development of an effective conventional vaccine against HIV-1. The HIV-1 gp120 is recognized by the C-type lectins of Langerhans cells (LCs), Langerin, in the mucosa and by the C-type lectins of dendritic cells (DCs), DC-SIGN in the sub-mucosa. Our aim was to analyze the presence of antibody able to block HIV / Lectins interactions. We have developed specific assays for the study of the binding of HIV-1 gp120 on human Langerin and DC-SIGN. With these assays, we have been able to characterize specific DC-SlGN and Langerin antibodies able to block fixation of conformational gp120 envelope protein. We have used our validated assays to monitor the prevalence of blocking antibodies in the sera of one hundred and ten HIV-1-infected individuals and thirty HIV-1 non-infected individuals. Only few patients have developed such type of antibodies during their infection. This is the first report which describes blocking antibodies in patients with the potential capacity to interfere during the mucosal transmission of HIV particles to mucosal DCs. The results provide a framework for the design of effective strategies to block local transmission and prevent HIV-1 spread. These tests will allow the measuring of the inhibition of gp120 binding to langerin or to DC-SIGN and the screening of different cohorts of HIV-1 positive subjects and HIV-1 negative but highly exposed subjects (HEPS)

Повний текст джерелаAlthough the issue of "young people and urban spaces" long remained cut off from the development of urban sociology in France, it has given to a growing interest since the early 80's. This interest is mainly due to the desire to try to understand violence in some neighborhoods with social problems, resulting in a new study ot the space appropriation process. In this study, we have sought to explain how this process emerged, through the anthropological rupture which is characteristic of the transition from childhood to adolescence. In fact, adolescence marks a decisive step in that it suddenly endowns a person with the ability to construct one's own reference points negotiated with adults, in a relationship called "symbolic paternity" or with other young people in a "parity" relationship. This potentiality lies inevitably within the framework of our era. We have, therefore, carried out 2 surveys, with the young people from Thouars and the young people from the Côtes-d'Armor departmental district. The results of this survey have demonstrated contrasts as regarding the awareness of regional membership, the attraction for an "urbanity" mode and the identification of places constituting "juvenile spatiality". And above all, they attest to the actualization of concomitant space forms that we have called "aims" : the "Appollinian" aim (attachment to the place), the "Faustian" aim (optimization of the "origin-destination" pair and the "linking aim" 'celebration of the path). But attesting to the existence of historically dated space forms is not enough. We have, therefore, endeavored to examine the postulate whereby the adolescent, unlike the child, is able to appropriate space. The results of tests carried out in a place totally unknown to children and young people have demonstrated significant disparities. The child, unlike the adolescent, proceeds with "absolutes" in his/her choices and seems to be lacking the reversibility principle. He/she is missing the capacity to find his/her way outside the space defined by the adult

Повний текст джерелаThe purpose of our study was to access the validity of the serodiagnosis ELISA type IgG and the urea breath test 13C(13C-UBT), in non invasive diagnosis and follow up of Helicobacter pylori infection (H pylori) in children. The results of a serological test (Cobas Core Roche, IgG, 2nd Generation) were compared with those of endoscopical gastric biopsies analysed by bacteriological culture and histology (reference method). This test seems to be sensitive and benefic, but a negative result does not exclude the diagnosis, especially in children under 10 years. On the other hand, this test exhibited a very poor sensitivity in the follow up of infection. Thus, endoscopical gastric biopsies for culture and histology remains the reference methode for the determination of acute H pylori infection in children. H pylori was searched for in children by bacteriological counts and culture on antral biopsies and by 13C-UBT. 13C-UBT is sensitive and specific in children ; it is correlated with biopsy bacteriological counts, suggesting the use of this test in the follow up of infection. The use of a two samples collected at T0 and T40 is also sensitive and specific and T40 seems to be the best discriminating time. The use of a single sample collected at T40 appears sufficient to define the H pylori status in children

Повний текст джерелаThe main object of our study was to investigate whether the resazurin metabolism assay is a sensitive alternative ocular irritation test in isolated pig cornea. Optimal incubation and measurement conditions of resazurin metabolism were determined. Comparisons between this fluorimetric assay and data collected in the ECETOC eye irritation reference chemicals data bank were performed using surfactants and alcohols as ocular irritant controls. We observed that the degree of surfactant- and alcohol-induced decrease in corneal viability using the resazurin reduction test was correlated with the in vivo irritancy measurements scored with the MMAS. The resazurin metabolism assay allows rapid assessment of many samples, with simple equipment and at reduced cost for continuous monitoring of corneal viability. This assay seems to be suitable as a toxicologic screening test for eye irritation determination

Повний текст джерелаTaking charge electrostatic of powder plays a significant role in their implementation in industrial processes. Poor flowability, reduced performance, impaired quality of product, process safety (explosion, abrasion lines)… are problems whose resolution requires a better understanding of the mechanisms occurring during the tribocharging. If the physical principles governing the behavior of continuum electrostatics, solids or liquides are well established, the suitability for electrification of dispersed materials (eg, powders and suspensions) is still poorly understood. This work aims to a better understanding of electrical phenomena of powders by establishing a reliable tool for its determination. The word focused on two axes : develpment of techniques for the characterization of intrinsic electrical property of powders and the development of an experimental device for tribocharging assessment. The work also allowed to compare several parameters that influence the charge generated in flowing such as size, shape, velocity of particles, nature of powders and walls. Finally, it a moded for predicting charge variation during particle-wall contacts in pneumatic conveying was established and validated

Повний текст джерелаConsidering the impact of overactivation of the PI3K/Akt/mTOR pathway in cancer, we chose to inhibit this signaling pathway. Given the high structural similarity between the PI3K and mTOR enzymes, we designed dual inhibitors targeting two of the three major kinases of the pathway. These inhibitors posses an original pyrido[3,2-d] pyrimidine scaffold. In order to provide a functional diversity and generate a therapeutic effect, the peaks C-4, C-2 and C-7 were functionalized sequentially in the following order. Position C-4 was first functionalized with aliphatic heterocycles by nucleophilic aromatic substitution. Then, various heteroaromatic rings were introduced at the C-2 position by Suzuki-Miyaura coupling. Finally, different functions were inserted at the C-7 peak by different reactions. In order to study the influence of the scaffold, the pyrido[2,3-d]pyrimidine isomer was also synthesized and functionalized. To test these original inhibitors a platform testing in vitro activities was set up in which five assay kits were optimized for the kinase PI3K, and one kit for mTOR. These tests exploit the TR-FRET and bioluminescence methods and were validated with commercially available inhibitors based on four factors: the correlation between IC50(literature) and IC50(measured), Z’, R², and S/B. In the end, more than sixty final products were evaluated in vitro on PI3K and mTOR. Half present an IC50 below 100 nM and 5 of them show an IC50 under 10 nM. As part of collaboration within the Cancéropôle Grand Ouest, the products were also tested on six cancer cell lines

Повний текст джерелаThe methodological development of a simplified approach to extract and quantify uranium and plutonium from fish samples by ICP-MS is the main goal of this master’s work. To do this, the cloud point extraction method (CPE) is used. This method allows the actinides to be separated from the matrix and preconcentrated in a small volume of surfactant. The use of a selective ligand makes it possible to form a complex with uranium and plutonium and then to transfer it inside the micelles. The ligand P, P-di (2-ethylhexyl) of methanediphosphonic acid (H2DEH[MDP]) is used because it has a high extraction potential for actinides. Since uranium and plutonium have a long-half-life, analyzes can be performed by ICP-MS, to know the isotopic ratios of the latter. However, prior to cloud point extraction and analysis, fish samples are processed to remove water and organic matter that can interfere with micelle formation. The various stages required for dissolution, their compatibility with the CPE approach and ICP-MS measurement will be presented for the analysis of large quantities (˃ 500 g) of fresh fishes

Повний текст джерелаThe increasing complexity of systems, hardware architectures and how to program them, leads to new paradigms in order to simplify developments. In this context, model-driven engineering (MDE) proposes to work with abstract representation of a system to help the designers to focus on the features of their systems rather than on implementation details. In this context, model transformations, and especially MDE compilation chain, offers to relieve the designers by offering them an automatic code generation from high-level models. However, the generated application does not always have the expected behavior or performance. In this thesis, we propose two approaches for the correction and optimization models based on model traceability. This work is based on the strong assumption that the transformation chain is trustworthy. To build such a chain, it is important to test the transformations that composed it. In order to help the chain developers when building an MDE compilation chain, we provide a way to locate errors in transformations and transformation chains. We also propose an assistant to help the developers during the mutation analysis technique which remains manual. This work was implemented in Gaspard, a co-design environment of embedded systems based on MDE compilation chain
