Full textSeereer traditional society is a peasant society based on subsistence farming. For a long time its main activity was millet, sorghum and corn farming, together with extensive livestock farming. Agricultural surpluses were made possible thanks to soil fertility and abundance of rain. Since the 1930's this society experienced profound social, economic and cultural mutations. First, through the introduction of cash crop peanut farming, then through the displacement of population policy from densely populated areas to less populated ones, and finally through the colonial legacy of independent Senegal. The progressive exhaustion of soils due to overexploitation combined with population pressure led to difficult access to land. The capital city of Senegal, Dakar, thus turned into the final destination of this population at risk. Despite harsh living conditions, leading to the creation of the federation of Seereer NGO's in Dakar, "Ndef Leng", which aims also at promoting the culture and endangered language of the Seereer, migration flows, involving all age groups, have not been stemmed

Full textThis work of thesis is situated in the continuity of the searches on the contacts of languages in Senegal, multilingual country. Senegal just like the other French-speaking African countries presents a sociolinguistic space characterized by contacts between national languages and the official language, French giving birth to a form to speak urban called "urban Wolof" or "franwolof".This study concerns the Wolof and the sérère, the national languages of Senegal, in touch with French, within the framework of uses which are made in the New information technologies and of the Communication still (NTIC). Analyses will be led compared to the oral practices and from the messages collected on Facebook and on discussion forums.How the national languages that are the Wolof and the sérère are valued in the linguistic practices and on the Internet ? This main interrogation will be associated with the following various questions of research : what relationships national languages (Wolof and sérère) they do maintain in the oral and with French in the on-line exchanges? / What differences with the oral practices? The Wolof and the sérère are they valued in the linguistic practices and in the electronic exchanges ? How the participants and the Internet users show their identities in their exchanges? How materialize the representations of the speakers with regard to (compared with) the languages which they speak ? What is the place of both national languages at the beginning of the 21th century in a Senegalese society marked by the multilingualism? What is the place of the languages in the definition of the identities of multilingual speakers? / What interests (in the material and symbolic point of view) are made by the use of these languages by the speakers? What roles for their valuation?To bring answers to these questions, the analysis will concern the notions of identity, representations, diglossia, the statutes of these three languages which coexist within the Senegalese territory, on the arrangement, the linguistic politics led to Senegal etc.This work will lean on an analysis of conversations realized with participants wolophones and schooled sérérophones or not and of data collected on Facebook and on discussion forums. This approach will allow to approach the manners the participants of which resort to both national languages in touch with French in the conversations and in the electronic papersKey words: sociolinguistics, multilingualism, New technologies of information and the communication, Codeswitching, Wolof language, serere language, valorization

Full textThe Serer of Senegal experienced a number of poor harvests between 1983 and 1985. The carry-over periods were often prolonged and sometimes lasted up to six months. The serer responded by establishing a strict and careful management of their resources. They were able to carry-over the reserves that had been already foreseen during the hivernage. At the same time they had to rely greatly on their savings in order to cover their living expenses. These savings were made possible thanks to a variety of activities in the village, to the agility of solidarity within the serer family structure, and finally to employment in the cities during the dry season. From now on, self-sufficiency in grain production will be guaranteed as much by the harvest as by purchase of imported goods, grants, and foreign aid. The response to the food shortage is no longer solely a local affair, but is interrelated to all the conditions of the society (migration, family network. )

Full textThis study (thesis) analyzes the conditions of knowledge change and therapeutic behaviors related to infantile malaria, in a context of biomedical diffusion (campaigns and sensibilization or public education). We considered urban migration which is generally perceived as a favorable context. This research focuses on a seereer siin population in Niakhar, a Mbour migratory community (Senegal). It is based on qualitative surveys (interviews, direct observations, life experiences) carried out on the residents and within community health care structures at both the rural and urban areas. Malaria, which is locally refered to as sumaan ndiig, is an ordinary disease which is not the subject of elaborate representations provided by the tradition. This specificity accounts for the possible and various reinterpretations of its etiology. Consequently, the cultural representations thus do not constitute barriers to its integration to the biomedical, in this process of construction. If urban areas offer a favorable context to its diffusion, the availability of an innovative biomedical knowledge is not enough to influence the evolution of such practices. Behavioural change aimed at improving the resort to biomedical care also depends on the socio-economic situation, contextual characteristics and the provision of heath care facilities that are at the disposition of migrants

Full textThe changes which have affected the agrarian system in this densely populated part of Senegal began to be felt as soon as the groundnut was introduced in the nineteenth century. However it was only following attempts - centered on groundnut production - to modernize agriculture that the rural system underwent a profound transformation. The vegetation cover has declined and the soil has become less productive, both surface and underground water bodies have become scarce, game has disappeared entirely, bovine herds have been driven towards Ferlo and the tann, and demographic pressure on the land has reached a peak. Today, many features of pre-colonial Sereer social organization subsist, but the changes underway herald an unprecedented upheaval. The agrarian transformations, the high density of the population, continual emigration at an increasingly early age, and the consequences of that emigration for the local economy, all continue to determine new conditions of land tenure, as well as new social, environmental and even political issues in the villages in the area

Full textLeebu, Serer and Wolof share some convergent customs and institutions. When a personality belonging to their ethnicities suffers of disorder of which etiology is referred to pangol-rab (invisibles creatures) occupying bodily and psychical space, NDEP is asked and practiced. What sort of problematic does it reveal? What efficiency does appear on it? Acknowledged as a collective therapy, doesn't it show in an individual and psychical dimension? In order to find answers to these questions, we have betaken ourself to Senegal to verify this hypothesis : the structuring process is accompanied with an anguish all the more as deep that culture prepares human to a form of being. Pulled about desire and reality, he unfolds codifiable symptoms amid his culture which settles a battery of therapies. Among those, Senegalese culture proposes one which refers to an analytical dimension and in the course of which the drawing up in language of what has been printed inside the subject brings him towards an anguish resolution and an inscription into the symbolic order which pre-exists towards him. This treaty argues a triple approach : - anthropological : conception of the human being, representation of disorder,- psychological : codification of madness, analysis of the situations, -psychoanalytical : real frame, imaginary and symbolic, so concepts such as signifying, phantasm, dream, body, myth, language, transfer. . . In a word, the intimate story of the subject, are asked through the underlying dynamic of dance, handling, watch songs but in the relation ndepe-ndepkat, too. This frame staying as a holder, the subject allows himself to untie his story and express his desire close to the ndepkat empowered to hear him. The accompaniment aims at the dislodgement of the rab towards the ancestral altar and the registration of the subject in his fathers' symbolic order

Full textThis thesis is part of a query on the modes of transmission in urban environment of Sereer ethnicity, associated par excellence with rurality in the Senegalese ethnic paradigm and deemed threatened of disappearance. The deconstructivist approach to ethnicity, essential in particular in the study of African "ethnic groups", proved to be insufficient for an adequate understanding of the experience of belonging lived by the respondents. It therefore seemed appropriate to remobilize the Weber notion of belief in a common origin, which opens up the possibility of reintegrating the subjective dimension of ethnicity experienced as a link of filiation between the members of the group and, in a complementary move inspired by the theory of social links and attachment regimes, of considering this link of filiation in its relation with other characteristic links of social life. Thus repositioned, ethnicity can be analyzed through the social frameworks of its formation, performance and transmission, and appears as a social fact in its own right which imposes itself to the sociologist. The field survey, conducted using the inductive method among people considering themselves as Sereer and living in Dakar and Paris, led to the finding of a strong diversity in the relation of those concerned to Sereer ethnicity. It appears that this relation is organized on the basis of the dominant ideal representation of a linear modernization, schematically opposing tradition and modernity, to which the theoretical approach of ethnicity itself is still partially subject. The analysis of the field survey material thus led to the construction of a typology of idealized relations with the origins and associated transmission modes. It appears that at the level of the group, Sereer ethnicity, reinterpreted according to the relational framework, at the international or national level, mobilizes differently the people claiming it. At a more individual and family level, the comparison of the words and the practices of the respondents with the typology made it possible to enlighten the way in which the relations with the origins, reshaped by social realities and a social positioning that are different for the members of the group, influence their family practices of transmission and the feeling of ethnic belonging of the descendants. Finally, it appears that, far from removing them from the social machine, ethnic experience puts the group and its reproduction plan to the test of various social factors in time and space, and poses in fact the question of what the social construct is about
Renaudier, Marie. "Dérivation et valence en sereer variété de Mar Lodj (Sénégal)." Thesis, Lyon 2, 2012. http://www.theses.fr/2012LYO20058/document.
Full textThis dissertation deals with the phenomenon of verbal derivation and valency changing in Sereer, an Atlantic language of Senegal. Analyses are based on spontaneous data and elicitations collected during fieldwork. The study is organized in three parts. The first part focuses on some points of Sereer grammar, like the complex verbal flexional morphology including aspect, person or focalization, which is strongly grammaticalized in this language. The second part provides the background required by the study of valency changing operations. Thus, it deals with the many derivational verbal suffixes of Sereer and distinguishes those which affect valency from those which do not affect valency. Moreover, this second part focuses on theoretical issues and provides definitions for the notions of grammatical relations, valency or voice. In Sereer, half of the 30 derivational suffixes imply a valency changing operation on the verb. These 15 morphemes encode 7 operations (causative, applicative, possession, passive, middle, reciprocal and antipassive) described in specific chapters beginning with a theoretical and typological frame. Syntactic and semantic consequences of verbal derivation but also functional motivations and non canonical structures constitute essential points of my description. In some cases, analysis of valency changing operations in Sereer confirms typological literature. This is the case of the causative for example. But some chapters focus on rare phenomena such as the external possession morpheme or the antipassive morpheme particularly specialized

Esta tese apresenta a associação de conversores CC-CC de duas portas conectados em série-série tanto na versão unidirecional quanto na versão bidirecional com comando único de controle. Inicialmente é realizado um estudo sobre os conversores CC-CC isolados bidirecionais de duas portas onde é proposta uma classificação para estes conversores com base no fluxo magnético de seus respectivos transformadores. Na sequência é realizado um estudo sobre a conexão série na entrada e série na saída de módulos CC-CC com característica externa em queda de tensão onde se verifica que para este tipo de módulo é possível realizar tal conexão de modo que haja equilíbrio nas tensões individuais dos módulos em ambos os lados da conversão sem a necessidade do uso de malhas de controle. Por apresentar característica externa em queda de tensão tanto no modo de condução contínua quanto no modo de condução descontínua, o conversor CC-CC isolado Ponte Completa com saída em tensão é estudado e utilizado como unidade modular da versão unidirecional da conexão série-série. O mecanismo de balanço da conxão série-série unidirecional é demonstrado analiticamente e comprovado via simulação. Resultados experimentais da conexão sériesérie unidirecional são obtidos a partir de um protótipo de 4 módulos, 4 kW, 1600V na entrada, 1600V na saída, 40 kHz e incluem operação em malha aberta, degrau na tensão de entrada e degrau de carga. O conversor Dual Active Bridge  DAB é estudado e utilizado como unidade modular da versão bidirecional da conexão série-série. Verificou-se analiticamente que na conexão série-série de módulos DAB sem perdas as tensões nos capacitores de cada módulo, tanto do lado  A quanto do lado  B da conversão, oscilam indefinidamente quando há um desequilíbrio nestas tensões, porém, ocorre o equilíbrio nestas tensões em termos de valores médios. Para a extinção das referidas oscilações é necessário que haja perdas de modo a proporcionar amortecimento para anulação das oscilações. Resultados experimentais da conexão série-série bidirecional são obtidos a partir de um protótipo de 4 módulos, 4 kW, 1600V no lado  A , 1600V no lado  B , 40 kHz e incluem operação em malha aberta com fluxo direto e operação em malha aberta com fluxo direto e reverso de modo a comprovar a bidirecionalidade do conversor.
Abstract : This thesis presents the association of DC-DC converters with two ports connected in series-series in both unidirectional and bidirectional version with single control. Initially is carried out a study on the isolated bidirectional DC- DC converters with two ports where it is proposed a classification for these converters based on magnetic flux in their transformers. In the sequence is carried out a study on the modular input-series and output-series connection of DC-DC converters with external characteristic type voltage drop where it can be seen that for this type of module it is possible to perform such a connection, so that there is balance in voltages of individual modules in both sides of the conversion without the need to use a control loop. By presenting external characteristic type voltage drop in both continuous conduction as in discontinuous conduction mode, the isolated DC-DC converter Full Bridge with voltage output is studied and used as a modular unit of unidirectional series-series connection version. The unidirectional series-series connection balance mechanism was analytically demonstrated and proven by simulation. Experimental Results of unidirectional series-series connection are obtained from a prototype with 4 modules, 4 kW, 1600 Vdc input, 1600 Vdc output, 40 kHz and include operation in open-loop, step on the input voltage and step load. The Dual Active Bridge  DAB converter is studied and used as a modular unit of bidirectional series-series connection version. It was verified analytically that in the series-series connection of lossless DAB modules the voltages across the capacitors of each module, both the side "A " and the "B" side of the conversion, oscillate indefinitely if there is an imbalance in these voltages, however, occurs balancing in these voltages in terms of average values. To extinguish these oscillations it is required losses to provide damping for cancellation of oscillations. Experimental results of the bidirectional series-series connection are obtained from a prototype with 4 modules, 4 kW, 1600 Vdc in side A, 1600 Vdc on side B, 40 kHz and include operation in open loop with direct power flow and operation in open loop with direct and reverse power flow in order to prove the bidirectional capability of the converter.

Built in institutional spaces and destroyed by the end of the shows, what remain of these experiments are the photographic records on these pages. The text is proposed here as a counterpart to these images, through which it would be possible to establish an entry to the thought involved in the conception of the works and to the ideas that originated within this practice.

O foco deste trabalho é o Ensino de Ciências da oitava série do Ensino Fundamental, com ênfase nos conteúdos de Química trabalhados. São apresentados os direcionamentos propostos em documentos oficiais nacionais e estaduais de Santa Catarina e de São Paulo para esta série. São destacados, também, os principais pontos de trabalhos desenvolvidos nesta série, em busca de um delineamento das principais tendências da área. Os livros didáticos de Ciências, indicados pelo Programa Nacional do Livro Didático 2005, foram analisados com a finalidade de se levantar os conteúdos químicos indicados para esta fase do ensino. A forma de apresentação destes conteúdos também foi considerada. Em contrapartida, buscou-se conhecer as características da prática em sala de aula por meio de entrevistas com professores de Ciências de turmas de oitava série de escolas públicas de Florianópolis,SC, e Araraquara,SP. Verificou-se que as tendências dos documentos oficiais e das pesquisas acadêmicas apontam para a interdisciplinaridade, abordagem temática e formação da cidadania, enquanto que a prática em sala de aula é influenciada pelos livros didáticos e tende a um ensino disciplinar, em que o ano letivo é dividido, principalmente, entre Química e Física. Como uma possível contribuição para amenizar os problemas encontrados neste contexto, foi desenvolvida uma proposta de ensino baseada nos pressupostos da Alfabetização Científica e Tecnológica. Para ilustrar de maneira mais prática a proposta de ensino, considerando as características das regiões das escolas consultadas, foram utilizados três temas: o Leite, o Mar e a Cana-de-açúcar. A proposta de ensino foi avaliada por professores de Ciências através de questionários.

A série didática Fontes compunha-se de uma cartilha de alfabetização e quatro livros de leitura, criados por Henrique da Silva Fontes. Adotada oficialmente para uso nas escolas primárias de Santa Catarina a partir de 1920 e utilizada até meados dos anos de 1950, a Série Fontes participou da formação de milhares de crianças catarinenses. Os livros de leitura, que constituem os dados privilegiados nesta pesquisa, consistem em antologias que reúnem textos tanto de Henrique Fontes quanto de outros autores. No campo da Linguística Aplicada, utilizando como base epistemológica a filosofia da linguagem do Círculo de Bakhtin e como abordagem teórico-metodológica a Análise Dialógica do Discurso (ADD), analisamos, nos quatro livros de leitura da Série de Leitura Fontes, a autoria, aqui tratada como posição enunciativa e como função organizadora do todo do enunciado. Tomando a Série Fontes em sua condição de enunciado, historiamos primeiramente o contexto social mais amplo da interação, especialmente o sistema educacional catarinense, desde a primeira metade do século XIX até a terceira década do século XX, e procuramos identificar os discursos que incidiam sobre a escola no momento da elaboração e publicação inicial da Série Fontes. A seguir, constituímos dados relativos à biobibliografia do autor Henrique Fontes e investigamos suas posições públicas manifestas em discursos e outros escritos, assim como já-ditos sobre Henrique Fontes presentes em escritos de pesquisadores e de coetânos. Em seguida, analisamos a Série Fontes nos seus aspectos de conteúdo-temático, composicionais e estilísticos, à busca de regularidades. A partir desses dados, analisamos como se constitui a autoria na Série Fontes como posição enunciativa, como elemento organizador do enunciado e como última instância da significação da obra (BAKHTIN, 1929). Por fim, mediante associação e contraposição dos dados constituídos pelas análises do contexto amplo da interação e da obra, analisamos a autoria da Série Fontes como ato ético responsável, segundo as teorizações sobre ato ético presentes em Para uma filosofia do ato responsável (BAKHTIN, 1920/1924). Para que um ato seja considerado ético, é necessário que faça coincidir a verdade abstrata, do mundo da cultura, universalmente válida (istina), com a verdade concreta do existir singular (pravda). As análises revelam que, no caso da Série Fontes, a autoria opera sobre o signo linguístico buscando o apagamento sistemático de todas as vozes contrárias ao projeto de dizer do autor, orientado pelas ideologias dominantes da época. Além disso, o enunciado-ato não é dirigido a sujeitos concretos sócio-historicamente situados, mas a um aluno e um professor abstratos, discursivamente construídos nas ideologias dominantes. Desta forma, a autoria faz com que coincidam apenas verdades abstratas. Concluímos que a autoria da Série Fontes, portanto, não satisfaz as condições necessárias a um ato enunciado ético.

Full textThe integration of the system's design notion takes share in the spirit of proximity and flexibility of companies' contemporary management. The reliability optimization, as well of the products manufactured as of the production equipment, is there of great importance. We were interested particularly in the problems of reliability and redundancy allocation. If reliabilities of the components may be unspecified values between zero and one, we developed, for the maximization of reliability under cost constraint, an algorithm which converges towards the optimum, for the systems parallel-series. In the case of the systems parallel-series, we proposed theoretical results and an approximate methode for the cost minimization under a reliability constraint. We were also interested in the case of reliabilities of the components which can be chosen among a whole of discrete values. This assumption takes account of the avaibility in components on the market. Pseudopolynomial algorithms for the problems of reliability and redundancy allocation were developed, for parallel series and parallel-series structures. These algorithms are dedicated to the minimization of the cost under reliability constraint and to the dual problem of reliability maximization. We generalized them for more complex structures

Full textFrom the late Nineteenth Century, in particular through Richard von Krafft-Ebing’s studies, new concepts have shaped the representations of sexual perversion. The study of the sexual dynamics in homicide cases changes the common methods of crime scene classification. In the Twentieth Century, these historical approaches lead to the study of a rare and particular phenomenon: serial sexual homicide. During the 1980s, the F.B.I dominates the field of practices and knowledge concerning the serial murder issue. Today, that domination is challenged. The F.B.I’s profiling methods are qualified as pseudo-scientific practice. Serial murder is nowadays more perceived as a simple social construction initiated by the Conservative politics of the Reagan years. According to some psychiatrists, the motivational model of the F.B.I has given a misleading picture of serial murder. The aim of the present work is to show that the main issue may not be to deconstruct the F.B.I’s studies, but to compare these first studies with current scientific research. Criminal profiling might be a method whose basic elements are likely to be corrected and completed. In this perspective, competing theoretical models, especially those held by psychoanalysis, also raise a number of difficulties. Of course, the intensity of sadistic fantasies can’t be the only dimension of criminal behavior. But fantasies probably interact with the desires and beliefs of the murderers. If serial sexual homicide appears to be, as most commentators agree, as a series of ritualistic acts, an anthropological approach may be legitimate. From this point of view, concepts such as “psychopathy”, “death drive” or “narcissism” do probably conceal the existence of a scapegoat mechanism by which killers are creating their own religion or mythology

Full textThis thesis aims at first studying a neglected series of landscapes by Cezanne done around chateau noir during a. 1895-1906, and, secondly, reconstitute Cezanne's colour in impressionnist aesthetics. The influence of Cezanne on abstract art is analyzed from a new point of view. Part II presents the place of chateau noir and the youth of cCezanne around tholonet, near Aix-en-Provence. His studies in Fontainebleau are considered together with his work at chateau noir. Part III treats the series of chateau noir and the art of Cezanne's time. The pictures are divised into two groups : architecture with trees, and trees and rocks. The fontainebleau are compared to the chateau noir. I remark the fragmentation of form, in the development from romanticism to impressionism. Part IV treats the chromatic harmony of Cezanne and its phenomenological aspect. I find the return of his youth in the colour of his last landscapes. Cezanne's multiple modulation of colours achieves a phenomenological, discontinuous spacial depth. His sensations of colours are also studied in the aesthetics of correspondances of Baudelaire. Part V outlines cezanne's modernity in the context of impressionnist aesthetics and fin-desiecle culture. Cezanne's phenomenological colour formulates the discontinous temporality, which is the implicit condition of impressionist subjectivity. I close this thesis on the influence of Cezanne on abstraction in discontinuous temporality - the dynamics and the opening of creative process

Full textThe main theorem of this PhD thesis states the following: the genus 0 coefficients of the quantum Witten- Kontsevich series defined by Buryak, Dubrovin, Guéré, and Rossi are equal to the coefficients of the polynomials defined by Goulden, Jackson, and Vakil in their study of double Hurwitz numbers. We also prove several other results on the quantum Witten-Kontsevich series. The classical Witten-Kontsevich series is a generating series of intersection numbers on the moduli spaces of stable curves. The Witten conjecture, proved by Kontsevich, asserts that this series is the logarithm of a tau function of the KdV hierarchy. In 2016, Buryak and Rossi introduced a new way to construct quantum integrable hierarchies, including a quantum KdV hierarchy. Buryak, Dubrovin, Guéré and Rossi then defined quantum tau functions, one of which is the quantum Witten-Kontsevich series. This series depends on two parameters: the genus parameter _ and the quantization parameter ~. It reduces to the Witten-Kontsevich series when we plug ~ = 0. One-part double Hurwitz numbers count non-equivalent holomorphic maps from a Riemann surface of genus g to P1 with a prescribed ramification profile over 0, a complete ramification over 1, and a given number of simple ramifications elsewhere. Goulden, Jackson and Vakil proved that these numbers are polynomial in the orders of ramification over 0. We show that the coefficients of these polynomials are equal to the coefficients of the quantum Witten-Kontsevich series with _ = 0. In Chapter 1, we present the setting of the classical and quantum integrable hierarchies that we will use. We also present the construction of classical and quantum tau functions. In Chapter 2, we present the moduli spaces of curves Mg;n and their tautological rings. We briefly review the Witten conjecture. Then we introduce the double ramification cycle and discuss various methods for computing it. This cycle is needed to define the Hamiltonians of quantum integrable hierarchies. In Chapter 3, we present the quantum KdV hierarchy and some of its properties. We then define the quantum Witten-Kontsevich series as a particular quantum tau function of this hierarchy. In Chapter 4, we introduce Hurwitz numbers. We first present a remarkable link between the quantum KdV hierarchy and the cut-and-join equation. Then we introduce the so-called one-part double Hurwitz numbers. Their relation with the quantum Witten-Kontsevich series is the main result ot this thesis. In Chapter 5, we present Eulerian numbers. These numbers appear in the computations of the coefficients of the quantum Witten-Kontsevich series. Their properties are crucial for our proofs. In Chapter 6, we formulate and prove our main theorem and other results on the quantum Witten- Kontsevich series

Full textThe Ser/Thr kinase mTOR complex 1 (mammalian Target Of Rapamycin) (mTORC1), his downstream effectors S6K1 (p70 ribosomal S6 kinase) and RSK (p90 ribosomal S6 kinase) are key regulators of insulin signaling and energy metabolism. The mTORC1/S6K1 pathway regulates cellular proliferation, growth, protein synthesis, lipogenesis, mitochondrial biogenesis, insulin signaling and inhibits autophagy. One of the most important roles of this signaling pathway is to integrate differents signals such as growth factors, energy status, oxygen, and nutrients. Thus, the mTORC1/S6K1 pathway is overactivated by nutrient excess conditions such as obesity. In addition, RSK is a downstream kinase of MAPK (mitogen-activated protein kinase) and it is also known to regulates cell proliferation, growth and to activate the mTORC1 pathway. Insulin and hyperglycemia are known to be among RSK activators. Therefore, mTORC1/S6K1 and RSK are involved in insulin resistance, obesity and type 2 diabetes. In a first study published in Diabetologia journal, we evaluated the effect of S6K1 inhibition with a selective S6K1 inhibitor, PF-4708671, on insulin resistance and energy metabolism. We used myotubes (L6) and hepatocytes (FAO) and observed that S6K1 inhibition increases glucose uptake in muscle and decrease glucose production in hepatocytes. In both cell type, S6K1 inhibition increases insulin-stimulating Akt phosphorylation. In addition, we treated obese mice fed high-fat diet for 1-week with S6K1 inhibitor. Mice treated with PF-4708671 have improved glucose tolerance and insulin-stimulating Akt phosphorylation in muscle, adipose tissue, and liver compared to obese mice treated with vehicle. Mechanistically, we showed in a 2nd study that this inhibitor inhibits S6K1 activity but also mitochondrial complex 1 which is associated with an increase in AMPK activation. Along with this study, we showed in a 3rd study published in J. Biol. Chem., that RSK1 phosphorylates directly IRS-1 on Ser1101 and RSK inhibition, by using either a RSK inhibitor (BI-D1870) or dominant-negative RSK1, improves insulin stimulating Akt phosphorylation as well as increasing glucose uptake in myotubes and inhibiting hepatic glucose production in vitro. Therefore, we demonstrated that RSK is a novel regulator of insulin signaling by phosphorylation Ser1101 of IRS-1. In conclusion, we are proposing that S6K1 inhibition and RSK1 inhibition are potential therapeutics targets to treat insulin resistance and type 2 diabetes.

Full textThe thesis is part of an ANR 'GENOPAT' project aiming to identify organic inhibitors of serine proteases involved in Netherton syndrome. Netherton's syndrome is a rare genetic skin disease caused by mutations in the gene encoding SPINK5 macromolecular inhibitor (LEKTI), it loses its regulating function of the activity of serine proteases (tissue kallikrein 5 , 7 and 14) esential for the skin homeostasis. There is currently no cure, topical application of exogenous inhibitors would therefore restore function of the epidermal barrier. Three strategies have been followed to identify new organic inhibitors of kallikreins, both rational approach and approaches based screening in silico and in vitro. 1) From a small laboratory collection of coumarin derivatives (240 molecules), suicide substrates of kallikreins were selected and characterized from a mechanistic point of view. 2) In parallel, a semi-rational approach based on the use of databases of experimental high throughput screening revealed 1,2,4-triazole compounds, forming acyl-enzyme with varying stabilities. 3) A virtual screening of the Chembridge commercial chemical library with about 600,000 organic molecules identified non-covalent kallikrein inhibitors, these inhibitors have a great structural diversity. Most inhibitors are among the most effective non-toxic with respect to healthy keratinocytes. Their effect on pro-allergic and inflammatory cytokines was analyzed in keratinocytes of patients with Netherton syndrome. A significant inhibition of the expression of these cytokines was observed

HK3 is thought to be responsible for the liquefaction of seminal plasma through proteolysis of the semenogelins, the major proteins forming coagulum immediately after ejaculation. Nevertheless, the physiological function of kallikreins hK2 and hK3 is still unclear. Men suffering from prostate cancer have high plasma concentrations of both kallikreins hK2 and hK3 which suggests that these two kallikreins could be involved in tumor growth. .

Experimentos recentes mostraram que, quando a inclinação q não é muito menor do que o ângulo crítico qc, a distribuição espacial dos deslizamentos obedece à relação de escala n(l) ~ l-(1+b), onde n(l) é o número de deslizamentos com magnitude l, e b=0.50±0.05. Esta lei de potência é reminiscente da lei de Gutenberg & Richter para a freqüência de um terremoto de momento sísmico s: n(s) ~ s-(1+g), onde g"0.5(r)0.6. Por outro lado, a análise de Hurst dessas séries revelou efeitos de persistência nos deslizamentos, correlação de larga escala temporal que desaparece no regime de inclinações mais baixas. O objetivo desta Tese é estudar a distribuição temporal dos deslizamentos em escalas de tempo mais reduzidas. Em particular, as séries no regime q<

Full textSeveral synthetic methods via magnesiated pyridines were developed to reach many compounds. The halogen-magnesium exchange was developed from many easily available bromopyridines. This reaction when proceeded at room temperature with isopropylmagnesium chloride gave the corresponding pyridylmagnesium chlorides, which could be trapped with various electrophiles. The metallation using isopropylmagnesium chloride or dibutylmagnesium as bases, directed by a secondary carboxamide or a pivaloylamino group at C2 led to 3-pyridylmagnesium halides, which were quenched by different electrophiles. At last, magnesiated benzenes and pyridines were involved in transition metals catalyzed couplings with many nitrogen p-deficient aromatic substrates. The reaction could proceed at low temperatures, allowing the use of substrates prone to nucleophilic attack or carrying reactive functions

Full textPancreatic beta cell constantly tunes insulin production to meet the body needs. The insulin production adaptation is achieved thanks to highly adaptive beta cell metabolism, signaling, secretory machinery and mass. The beta-cell function and mass plasticity are particularly critical during nutritional, body growth and physiological changes such as obesity, pregnancy and postnatal development of newborn. Functional beta cell demise account for diabetes is one of the leading causes of death worldwide.In vertebrates, serine-threonine kinases (STKs) drive key signaling pathways for adaptive cells response to the environment. The overall goal of the thesis was to identify the signaling pathways responsible for the development of beta cell mass during postnatal development, pregnancy and obesity. Identification of these signaling pathways may help in understanding the functional beta cell mass demise induced by the diabetogenic environment (e.g oxidized LDL, hyperglycemia, hyperlipidemia, etc.) in diabetic patients. By investigating beta cell mass plasticity in 10 day old neonate rats, we found a significant increase in the expression of Dual Leucine Zipper Kinase (DLK) protein when compared to islets from adult rats. In islets of pups, the increase of DLK expression coincides with a very high proliferative rate of beta cells and activation of "cJun-amino terminal Kinase 3" (JNK3) signaling, an STK belonging to “mitogen activated protein kinase” (MAPKs) family. As observed for DLK, in islets of rat pups, the genetic disruption of JNK3 drastically reduces the number of beta cells leading to glucose intolerance. Finally, we also observed that MAPKs link oxidized LDL to beta cell death via mechanisms involving endoplasmic reticulum stress and oxidative stress. Our results show the critical importance of MAPK signaling in controlling beta cell survival and proliferation in response to physiological condition and diabetes

Full textMAC methodology is a synthetic technique which employs an umpolung reagent to formally insert a carbonyl function between an electrophile and a nucleophile. This thesis is devoted to the diastereoselective oxyhomologation of L-serine thanks to a significant development of 3-component one pot MAC methodology, providing a synthesis of orthogonally-protected derivatives of α, γ-dihydroxy-β-aminobutyric acid. This latter is a highly functionalized, acyclic, 4-carbon molecular building block which is a constituent part of various biologically active molecules.The synthesis of silylated MAC reagents from malononitrile was first studied. H-MAC-TBS’s synthesis was optimized and two new silylated MAC reagents, H-MAC-TES and H-MACTBDPS,were prepared.In a first study, the oxyhomologation of N-Boc-O-Bn-L-serinal was examined using H-MACTBS and a panel of alcohols in mild conditions.Methyl esters of orthogonally-protected α, γ-dihydroxy-β-aminobutanoic acid were prepared in good yields and with a diastereoisomeric ratio syn/anti = 80/20. The use of H-MAC-TBDPS improved the diastereoselectivity of the MAC reaction to syn/anti = 90/10.Subsequently, different cyclization modes of methyl α, γ-dihydroxy-β-aminobutanoate were investigated, leading to the selective synthesis of functionalized 3-, 5- and 6-membered ring heterocycles, including new highly functionalized oxazolidinones et oxazolines. In contrast, despite considerable efforts, we were unable to induce cyclisation to forma a 4-membered ring heterocycle, due to the surprising lack of nucleophilicity of the free alcohol function in the acyclic precursors.In a second study, we examined the oxyhomologation of Garners aldehyde, a cyclicN,O-protected derivative of L-serinal, using a selection of nucleophiles via one-pot MAC methodology. These reactions furnished protected ester and amide derivatives of α, γ-dihydroxy-β-aminobutyric acid in good yields with an anti diastereoselectivity with a ratio as high as syn/anti = 10/90 when H-MAC-TBDPS was used as the MAC reagent. These are the first known examples of MAC reactions which proceed with anti diastereoselectivity.Functionalized 3- and 5-membered ring heterocycles were prepared from these adducts,and via selective oxidation at the γ-position,orthogonally-protected derivatives of erythro-β-hydroxyaspartic acid and erythro-β-hydroxyasparagine were prepared

Full textInflammation has been demonstrated to play a central role in chronic obstructive pulmonary diseases (COPD). Neutrophil influx leads to a massive release of neutrophil serine proteases elastase (NSPs): elastase (HNE), proteinase 3 (Pr3) and cathepsin (CG) thereby leading to a protease/anti-protease imbalance. Besides the proteolytic damages to the lung extracellular matrix proteins, these proteases stimulate secretion of pro-inflammatory cytokines and therefore contribute to the perpetuation of inflammation. In order to target these proteases in COPD, we have examined the capacity of trappin-2 A62L (A62L T2), a genetically modified inhibitor which is able to inhibit all three serine neutrophil proteinases at the same time to protect the alveolar epithelium of the deleterious effects caused by the NSPS. In our study, we showed that T2 A62L significantly inhibits cell detachment and degradation of cell junction proteins (E-cadherin, ß-catenin and ZO-1, zonula occludens-1) of alveolar epithelial cells (A549) induced by each individual NSPS or by activated neutrophils. In addition to their antiproteolytic action T2 and T2 A62L reduced proinflammatory cytokines IL-6 and IL-8 release by A549 cells, previously stimulated by HNE or Escherichia coli lipopolysaccharide (LPS)
