Réseaux de régulation chez Escherichia coli / Gene regulatory network in Escherichia coli

Baptist, Guillaume 29 August 2012 (has links)
L'adaptation d'une bactérie aux changements de son environnement est contrôlée par un réseau de régulation large et complexe, faisant intervenir de nombreux acteurs et modules différents. Dans ce travail, nous avons étudiés un module de régulation spécifique, contrôlant l'adaptation de la bactérie Escherichia coli à un changement de sources de carbone. Dans un milieu contenant du glucose et de l'acétate, la croissance est divisée en deux phases : les bactéries utilisent préférentiellement le glucose et commencent à métaboliser l'acétate qu'après l'épuisement du glucose. En effet, la présence du glucose réprime la transcription d'un gène nécessaire à la croissance sur acétate, le gène acs (codant pour l'acétyl-CoA synthétase). Le mécanisme régulateur fait intervenir le facteur de transcription Crp-AMPc et le système de transfert de phosphate (PTS), qui permet l'import du glucose. Plusieurs modèles décrivent en détail la cascade de réactions moléculaires à l'origine de cette « répression catabolique ». Cependant, certaines de nos observations expérimentales ne sont pas correctement prédites par les modèles actuels. Ces modèles doivent être révisés ou complétés. L'outil majeur que nous employons pour les expériences est la fusion transcriptionnelle : une région promotrice fusionnée en amont d'un gène rapporteur (GFP, luciferase). Avec ces constructions, nous mesurons la dynamique de l'expression génique dans différentes souches (mutants) et différentes conditions environnementales. Les observations à l'échelle de la population sont corroborées par des mesures similaires à l'échelle de la cellule unique. Nous utilisons cette même technologie pour construire de petits systèmes synthétiques qui sondent davantage le phénomène de répression catabolique. Nous avons ainsi créé un interrupteur génétique dont le fonctionnement est contrôlé par le flux glycolytique et nous avons construit un petit système de communication intercellulaire basé sur la molécule AMPc. Enfin, nous proposons une manière originale de mesurer l'état métabolique des cellules en utilisant la dépendance énergétique de la luciferase. / The adaptation of bacteria to changes in their environment is controlled by a large and complex regulatory network involving many different actors and modules. In this work, we have studied a specific module controlling the adaptation of Escherichia coli to a change in carbon sources. In a medium containing glucose and acetate, growth is divided into two phases : the bacteria preferentially use glucose and start to metabolize acetate only after glucose exhaustion. Indeed, the presence of glucose represses the transcription of a gene needed for growth on acetate : the acs gene (coding for acetyl-CoA synthetase). The regulatory mechanism involves the Crp-cAMP regulator and the phosphate transfer system (PTS), which is responsible for glucose import. Several models describe the cascade of molecular reactions responsible for this « catabolite repression ». However, our work shows that many of our experimental observations are incorrectly predicted by current models. These models have to be amended.We use transcriptional fusion, i.e., the fusion of a promoter region upstream of a reporter gene (GFP, luciferase), to measure the dynamics of gene expression in different genetic backgrounds and environmental conditions. Observations at the population level are corroborated by similar measurements at the single cell level. We use this same technology to construct small synthetic systems that probe further aspects of the phenomenon of catabolite repression. We have thus created a genetic toggle switch controlled by the glycolytic flux and we have built an inter-cellular communication system mediated by cAMP. Finally, we propose a novel way to measure the metabolic state of cells by using the energy dependence of the luciferase enzyme.

Ao realizar um trabalho meticuloso de vigilância e repressão, a polícia política não somente coletou, registrou e ofereceu dados sobre suspeitos a outros setores ou Delegacias Regionais, mas associou o comunismo a características negativas, atribuiu a seus adeptos um alto grau de periculosidade e identificou na doutrina comunista elementos que supostamente visavam destruir o mundo ocidental e seus valores. Tais características contribuíram para a formação do mito da conspiração comunista, o qual se alimentava da disseminação do medo e da paranoia de que o “inimigo vermelho” poderia estar em todos os lugares, com grande força e blindado por suas características maléficas. A confluência de mitos políticos não ficou restrita ao universo policial. Por outro lado, os próprios comunistas paranaenses se alimentaram de mitos, seja para manter sua própria unidade, existência ou até mesmo para se sentirem motivados na busca pela luta revolucionária. Apesar das adversidades físicas, emocionais e familiares, acreditavase que o papel de revolucionário e a entrega de sua vida em sacrifício trariam recompensas, como o fim da exploração capitalista e a construção de uma sociedade mais justa. Para a escrita do trabalho foram utilizadas fontes de natureza jornalística, entrevistas, depoimentos, relatórios e demais evidências arquivadas no Fundo DOPS do Arquivo Público do Estado do Paraná e Arquivo Pessoal de Teresa Urban. O foco principal se concentrou no esforço de identificar na documentação indícios de mitos políticos modernos, em especial o mito da conspiração comunista e, na sua antítese, as construções mitológicas formuladas no interior do PCB, a exemplo do mito da unidade e do mito da Idade de Ouro. Pessoas comuns, militantes, agentes policiais, todos esses personagens foram analisados de forma a demonstrar que os mitos políticos adquirem roupagens diferenciadas em consonância com o pensamento que se deseja legitimar por um indivíduo, instituição ou grupo. / This thesis analyzes the modern political myths that have formed in the relationship between the Bureau of Political and Social Order (DOPS/PR) with communism and activities of the Communist Party of Brazil (PCB) in Paraná during the years 1945- 1953. To conduct a meticulous surveillance and repression, the political police not only collected, recorded and offered data on suspects to other sectors or Regional Offices, but associated communism the negative characteristics attributed to his followers a high degree of dangerousness and identified in Communist doctrine elements that allegedly aimed to destroy the Western world and its values. These characteristics contributed to the formation of the myth of the communist conspiracy, which fed the spread of fear and paranoia that the "red enemy" could be everywhere, with great strength and armored by his evil characteristics. The confluence of political myths was not restricted to the police universe. On the other hand, Paraná Communists themselves fed on myths, is to maintain its own unity, existence or even to feel motivated in the pursuit of revolutionary struggle. Despite the physical, emotional and family adversity, it was believed that the revolutionary paper and the delivery of his life in sacrifice would bring rewards, as the end of capitalist exploitation and the construction of a fairer society. For writing the work they were used sources of journalistic nature, interviews, statements, reports and other evidence filed with the Fund DOPS of Paraná State Public Archive and Personal Archive of Urban Teresa. The main focus was in the effort to identify the documentation evidence of modern political myths, especially the myth of Communist conspiracy and, in its antithesis, mythological constructions made inside the PCB, the unity of the myth of the example and the Middle myth of gold. Ordinary people, activists, police officers, all these characters were analyzed in order to demonstrate that political myths take on different guises in line with the thought that if you want to legitimize by an individual, institution or group.

Zásada subsidiarity trestní represe / The Principle of Subsidiarity of Criminal Repression

Drobílek, Michal January 2018 (has links)
The Principle of Subsidiarity of Criminal Repression Abstract This Master's Thesis deals with the principle of subsidiarity of criminal repression, one of the basic principles of substantive criminal law, which was first enacted in the Czech criminal law as lately as in the new 2009 Criminal Code. The principle of subsidiarity of criminal repression is expressed by the fact that the means of criminal law can be applied only in socially harmful cases where the application of criminal liability is not sufficient under another legal enactment. Simultaneously, this principle of subsidiarity of criminal repression expresses the nature of criminal law as a means of the ultima ratio, i.e. the ultimate solution. After the introduction of the functions and purpose of the criminal law itself in terms of historical development and present, an analysis of the valid legal regulation of the principle of the subsidiarity of criminal repression is presented. Adoption of the principle of the subsidiarity of criminal repression into the new Criminal Code has led to an unprecedented wide-ranging discussion of its importance in criminal law, especially its impact on the issues of the basis of criminal liability. The problems often mentioned in this discussion are in particular dealt with in the chapter on the concept of crime,...

Informovanost veřejnosti o drogové problematice v okrese České Budějovice / Public awareness of drug problems in České Budějovice district

KOZLOVÁ, Lucie January 2008 (has links)
ABSTRACT Addictive drugs are all around us and they have become a part of our lives. The issue of drug abuse is of critical importance, global, and difficult to solve. Typically, drugs are categorized as tolerated or not tolerated by society, and more or less risky. It is vital, therefore, to know the attitude of public to the issue. Lots of drug abuse causes have already been revealed, just like the reasons why some users develop addiction while others do not. In all probability the abuse of drugs or the addiction development cannot be put down to a single background factor. Everything will depend on personality traits of the individual, on his or her environmental conditions, and on specific effects of the drug. Since I take much interest in these issues, I have chosen for my thesis the subject of Public awareness of drug abuse issues in the District of České Budějovice. I investigated what people knew about drug abuse at the District where I live; their opinions of drug abuse; whether they believed that drug abuse deteriorated social position of an individual; whether they believed it boosted the rate of crime; if people were informed about facilities assisting recovery from drug addiction within the District of České Budějovice; and, last but not least, whether they suspected what drugs could come in their way here. The thesis aimed to examine what people knew about the drug abuse issues in the České Budějovice District. This objective has been met. Fifty three percent of respondents were found well informed on the subject, while the remaining 47% lacked the information. The survey was to prove or disprove hypothesis that the public was unaware of organizations providing help to drug addicts - the hypothesis was not confirmed since 51% of respondents were informed about the relevant organizations and 49% were not. Another hypothesis predicted that the public could not tell the illegal drugs from the legal ones - it was not confirmed as the public was found sufficiently informed. The hypotheses expecting the public to believe that drug abuse drives crime and deteriorates the addict's social position were confirmed by the bulk of respondents living in the District of České Budějovice. Ninety nine percent of the respondents believed the drug abuse pushed up the crime rate and 95% were of the opinion that it affected the addict's social position. As follows from the survey, the public in the České Budějovice District was relatively well informed of the drug abuse issues, though the differences encountered between awareness and unawareness of the subject were just minor. I intend to release the thesis as an information source for the general public(in the form of brochures, internet publications or periodicals); moreover, I want to offer the results to organizations engaged in the drug abuse treatment and to students of the University of South Bohemia to serve as training material. The public will find a wealth of important drug-related information in the paper, while the addiction treating organizations will be prompted to fill the gaps still existing in information available to the general public.

Instinct and civilization: Norbert Elias's procedural sociology and his encounter with Freudian psychoanalysis / Instinto e civilizaÃÃo: a sociologia processual de Norbert Elias e seu encontro com a psicanÃlise freudiana

Francisco Daniel Iris Goiana 01 August 2014 (has links)
CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / This work make a reflective analysis on the work of the sociologist Norbert Elias, especially in its interpretation of the civilizing process occurred in Europe from the formation of European absolutist states, present in The Civilizing Process (1939). In the constitution of his Sociology, Elias brings an interdisciplinary proposal to sociologically analyze a historical object. For this analysis, the author makes use of freudian psychoanalysis. I tried to make this work, first an analysis sociobiographical Freud and Elias, addressing his intellectual formation, looking for a 'meeting point' of these two authors. Specifically, this site was the Frankfurt School, which had a very strong relationship between social theory and psychoanalysis, which influenced authors such as Herbert Marcuse and Theodor Adorno. In his life, Elias comes into contact with Freud's work during the period he was in the city (1929- 1933), when he was assistant Karl Mannheim. The initial period of Elias in Frankfurt coincides with the release of Civilization and its Discontents, the great work in which Freud, even starting from a clinical assumption makes a great analysis of the social. Elias falls into a tradition of authors who used psychoanalytic theory as support for the construction of both theories in the field of Sociology and Anthropology. So we did a genealogy of this interaction and realize that it occurs almost simultaneously with the emergence of sociology, anthropology and psychoanalysis, with Freud himself one of the authors to make this interaction in works such as Totem and Taboo and Civilization and its Discontents, among others. Based on these works and concepts formulated by Freud to the ideas of 'superego', 'instinctual repression', Elias constructs his theory of the 'civilizing process'. This process, Elias tells us that is mostly based on a repression of affects and emotions process, which in Freud's language is the 'repression of instincts' which leads to the formation of the superego, our moral censor. For Elias this 'repression' occurs in two stages: first through an external coercion, with the emergence of feelings such as shame that path leads to internalization of these prohibitions causing individuals to self-control their emotions, such a rationalization process. When formulated his idea of 'civilizing process', Elias also postulated that this process is not unilinear and is not totally safe thus resulting in the idea of 'descivilizing process' that occur in situations such as wars and genocides and Elias analyzed in its The Germans work. / Este trabalho faz uma anÃlise reflexiva sobre a obra do sociÃlogo Norbert Elias, especialmente na sua interpretaÃÃo sobre o processo civilizatÃrio, ocorrido na Europa a partir da formaÃÃo dos estados absolutistas europeus, presente em O processo civilizador (1939). Na constituiÃÃo de sua Sociologia, Elias traz uma proposta interdisciplinar de analisar sociologicamente um objeto histÃrico. Para tal anÃlise, o autor faz uso da psicanÃlise freudiana. Nesse trabalho busquei fazer, primeiramente uma anÃlise sociobiogrÃfica de Freud e Elias, tratando de sua formaÃÃo intelectual, procurando um âponto de encontroâ desses dois autores. Concretamente, esse local foi a Escola de Frankfurt, onde havia uma relaÃÃo muito forte entre a teoria social e a psicanÃlise, que influenciou autores como Hebert Marcuse e Theodor Adorno. Em sua vida, Elias entra em contato com a obra freudiana no perÃodo que ficou na cidade (1929-1933), quando era assistente de Karl Mannheim. O perÃodo inicial de Elias em Frankfurt coincide com o lanÃamento de O mal-estar na civilizaÃÃo, a grande obra em que Freud, mesmo que partindo de um pressuposto clÃnico faz uma grande anÃlise do social. Elias se enquadra em uma tradiÃÃo de autores que usaram a teoria psicanalÃtica como apoio para a construÃÃo de teorias tanto da Ãrea da Sociologia como da Antropologia. Portanto, fizemos uma genealogia dessa interaÃÃo e percebemos que ela ocorre quase que simultaneamente com o surgimento da Sociologia, da Antropologia e da PsicanÃlise, sendo o prÃprio Freud um dos autores a fazer essa interaÃÃo em obras como Totem e Tabu e O Mal-estar na civilizaÃÃo, dentre outras. Baseado nessas obras e por conceitos formulados por Freud com as ideias de âsupereuâ, ârepressÃo instintualâ, Elias constrÃi sua teoria do âprocesso civilizadorâ. Esse processo, Elias nos diz que està baseado majoritariamente num processo de repressÃo dos afetos e das emoÃÃes, que na linguagem freudiana à a ârepressÃo dos instintosâ que leva a formaÃÃo do supereu, nosso censor moral. Para Elias essa ârepressÃoâ ocorre em dois momentos: primeiro por meio de uma coerÃÃo externa, com o surgimento de sentimentos como a vergonha esse caminho leva à internalizaÃÃo dessas proibiÃÃes levando os indivÃduos ao autocontrole de suas emoÃÃes, num processo de racionalizaÃÃo dessas. Quando formulou sua ideia de âprocesso civilizadorâ, Elias postulou tambÃm que esse processo nÃo à unilinear e que nÃo està totalmente a salvo surgindo assim a ideia de âprocesso descivilizadorâ que ocorrem em situaÃÃes como guerras e genocÃdios e que Elias analisou na sua obra Os alemÃes.

Análise de redes metabólicas em Saccharomyces cerevisiae. / Metabolic network analysis of Saccharomyces cerevisiae.

Andreas Karoly Gombert 17 May 2001 (has links)
Análise de Redes Metabólicas foi aplicada à cepa de Saccharomyces cerevisiae CEN.PK113-7D, e a alguns mutantes interrompidos em genes que codificam para proteínas regulatórias envolvidas no fenômeno de repressão por glicose. Todas as cepas foram cultivadas em aerobiose, em meio mínimo contendo [1-13C]glicose como substrato limitante. As células eram recolhidas em situação de crescimento balanceado e submetidas à hidrólise, seguida de derivação e posterior injeção da amostra resultante num cromatógrafo gasoso acoplado a um espectrômetro de massa, para análise da marcação em alguns fragmentos de metabólitos intracelulares. Estes dados serviram como base para a identificação da atividade de algumas vias metabólicas no metabolismo central de S. cerevisiae. Além disto, utilizando-os juntamente com um modelo estequiométrico, foi possível obter uma estimativa para os fluxos no metabolismo central na cepa referência e nos mutantes estudados. Num primeiro momento, a metodologia foi validada para cultivos contínuos e descontínuos. Calculou-se um desvio padrão para a medida da marcação em cada fragmento de metabólito detectado pela metodologia empregada. Na cepa referência, observou-se que o ciclo de Krebs opera de forma cíclica em células que respiram e de forma não cíclica em células que apresentam metabolismo respiratório-fermentativo. Verificou-se que uma maior parte da glicose consumida é desviada para a via das pentoses fosfato no primeiro caso, em relação ao segundo. Foram encontradas evidências para a biossíntese de glicina através da enzima treonina aldolase e para a atividade da enzima málica. A ausência das proteínas Mig1 e Mig2 não altera os padrões de crescimento, produção de etanol e de marcação em metabólitos intracelulares de S. cerevisiae. Já a ausência de Hxk2, Reg1 ou Grr1 provoca alívio na repressão por glicose, observado pelo aumento das atividades respiratórias. / Metabolic Network Analysis was applied to the reference strain CEN.PK113-7D of Saccharomyces cerevisiae, as well as to some mutants disrupted in genes which code for regulatory proteins involved in the glucose repression cascade. All strains were cultivated under aerobic conditions, using minimal medium with [1-13C]glucose as the limiting substrate. Cells were harvested under balanced growth conditions and submitted to hydrolysis, derivatization and injection of the sample into a gas chromatograph coupled to a mass spectrometer for analysis of the labeling pattern in some fragments of intracellular metabolites. These data were used for identifying the activity of some pathways in the central metabolism of S. cerevisiae. Furthermore, using the data together with a stoichiometric model, it was possible to estimate the fluxes in the central metabolism of the reference strain and in the mutant strains. First, the methodology was validated for batch and continuous cultivations. Standard deviations were calculated for the measurement of the fractional labeling in each of the detected fragments. In the reference strain, it was observed that the Krebs cycle operates in a cyclic manner in respiratory cells, whereas it operates in a non cyclic manner under respiro-fermentative metabolism. It was also seen that a greater part of the glucose consumed by the cells enters the pentose phosphate pathway in the former than in the later case. Evidence for the activity of the threonine aldolase and the malic enzyme catalyzed reactions was also found. The absence of the Mig1 and Mig2 proteins does not alter the growth, ethanol formation and labeling pattern of intracellular metabolites in S. cerevisiae. In contrast, the absence of Hxk2, Reg1, or Grr1 provoques a relief in glucose repression, which was observed by an increased respiratory activity.

Entre dois agostos: o Conselho de EducaÃÃo do Cearà na dÃcada de 1970 - 1979 / Between two Augusts: the Board of Education of Cearà in the decade from 1970 to 1979

Jeimes Mazza Correia Lima 23 July 2013 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / nÃo hà / O estudo realizado sobre a atuaÃÃo do Conselho de EducaÃÃo do Cearà tem por finalidade a compreensÃo de como a instituiÃÃo estruturou, atravÃs de legislaÃÃes educacionais vigentes na dÃcada de 1970, a educaÃÃo escolar cearense. Essa organizaÃÃo foi conduzida atravÃs de pareceres e resoluÃÃes especÃficos, portanto os meios disponÃveis para essa finalidade, proporcionando o entendimento sobre a eventual existÃncia de interpretaÃÃes legais, por parte dos pareceristas, os Conselheiros da EducaÃÃo, dotando-os de uma capacidade de atuaÃÃo no CearÃ, extrapolando e distorcendo suas funÃÃes especÃficas, que era o de interpretar e aplicar a legislaÃÃo educacional definida pela reforma de 1971, atravÃs da Lei 5692/71, atendendo a uma determinaÃÃo dos governos autoritÃrios do perÃodo, dotado de caracterÃsticas vinculadas as restriÃÃes de liberdade individual e coletiva, comuns na Ãpoca. Para isso foi utilizado para analise um conjunto de documentos, fontes escritas, produzidos ao longo de uma dÃcada pela instituiÃÃo, com seu carÃter oficial, constando as interpretaÃÃes, posicionamentos e definiÃÃes sobre educaÃÃo escolar e o momento polÃtico. Com base nessa documentaÃÃo, com a mediaÃÃo de outras fontes pertinentes a Ãpoca, percebeu-se que apÃs sua refundaÃÃo em 1965 pelo governador cearense VirgÃlio TÃvora o Conselho buscou legitimar suas aÃÃes na sociedade local, e gradualmente, de forma coercitiva estabeleceu uma organizaÃÃo da educaÃÃo escolar no Cearà no cumprimento das normas, leis e regras vigentes. Apesar de ser uma instituiÃÃo vinculada ao Estado nÃo hà indicaÃÃo clara de que se desenvolveu um conjunto de atos administrativos restritivos de liberdade, alÃm da adoÃÃo de puniÃÃes as escolas ou a seus integrantes, diretores, professores e secretÃrios escolares, bem como estudantes, atendendo a uma deliberaÃÃo direta dos organismos de repressÃo polÃtica desenvolvidos no perÃodo. Com isso à possÃvel aferir que: foi ineficaz o uso do Conselho de EducaÃÃo do Cearà na dÃcada de 1970 com fins a atender a repressÃo polÃtica aos movimentos de contestaÃÃo ao regime autoritÃrio em grande parte com a participaÃÃo de estudantes secundaristas. / The study on the performance of the Board of Education of Cearà aims at understanding how the institution structured through educational legislation in force in the 1970s, school education CearÃ. This organization was led by opinions and resolutions specific, so the means available for this purpose, providing the understanding of the possible existence of legal interpretations by the referees, the Board of Education, giving them an ability to act in Cearà extrapolating and distorting their specific functions, which was to interpret and apply the law determined by educational reform, 1971, by Law 5692/71, in response to a determination of the period of authoritarian rule, endowed with characteristics related restrictions on individual freedom and collective, common at the time. For it was used to analyze a set of documents, written sources, produced over a decade by the institution with their official, stating interpretations, positions and definitions of school education and political momentum. From this documentation, with mediation from other sources relevant to the season, it was noticed that after its re-foundation in 1965 by the governor of Cearà Virgilio Tavora the Council sought to legitimize their actions in the local society, and gradually, coercively established an organization of education school in Cearà in compliance with standards, rules and legislation. Although an institution linked to the State no clear indication that developed a set of administrative acts restrictive of freedom, besides adopting punishments schools or their members, directors, secretaries and school teachers as well as students, attending deliberation direct bodies of political repression developed in the period. With this it is possible to infer that: was ineffective use of the Board of Education of Cearà in 1970 with the purpose to serve the political repression of opposition movements to the authoritarian regime largely attended by high school students.

No presente estudo avaliamos o padrão de regulação dos genes do metabolismo central do nitrogênio na levedura Dekkera bruxellensis. Foram definidos quatro grupos de fontes de nitrogênio baseados no crescimento celular. Em seguida, o padrão de expressão dos genes do metabolismo central do nitrogênio mostrou que fenilalanina, embora do grupo quatro, é o maior indutor das permeases Gap1p e Put4p, resultando em sua elevada taxa de consumo. Já a histidina, indutora da permease Put4p, promove maior indução dos genes que codificam as enzimas de assimilação de amônia. Quando o mecanismo NCR é inibido pela presença de metionina sulfoximina no meio, ocorre a desrrepressão dos genes que codificam as permeases. E finalmente, os resultados mostram que nitrato, definido no grupo dois induz o mecanismo de sinalização intracelular de regulação gênica semelhante ao que se observa quando as células estão no estado de privação de nitrogênio no meio. Isto complementa os estudos anteriores nos quais mostramos que a assimilação de nitrato altera o estado fisiológico da célula para respiração mesmo na presença de alta concentração de glicose no meio. / The nitrogen sources in the medium are classified as preferential or non-preferrential, so that the first inhibit expression of genes responsible for metabolism of the latter by a mechanism called Nitrogen Catabolic Repression (NCR). In the present study we evaluated the pattern of gene regulation of the central nitrogen metabolism in yeast Dekkera bruxellensis. It was defined four groups of nitrogen sources based on cell growth. Then, the expression pattern of the central nitrogen metabolism genes showed that phenylalanine, though belonging to group four, is the biggest inducer of genes of permeases Gap1p Put4p, resulting in its high consumption rate. Moreover, histidine induces the gene encoding permease Put4p and promoted the highest induction of the genes encoding the enzymes of ammonia assimilation. When the NCR mechanism was inhibited by the presence of methionine sulfoximine in the medium there was derepression of the genes encoding for permeases. Finally, the results showed that nitrate, defined in the group two, induced the intracellular signaling pathway gene regulation similar to that seen when cells are in a state of nitrogen deprivation in the middle. This complements our previous studies that showed that the nitrate assimilation alter the physiological state of the cell to respiration even in presence of high glucose concentration in medium.

O objetivo geral é, pois, identificar quais e como são não só os sentidos e representações que tanto o exército quanto os oficiais reformados atualizam e elaboram para evocar e justificar a assim chamada ¿luta contra a subversão¿, mas também as práticas comemorativas que encenam junto às famílias e às organizações cívico/militares para homenagear os oficiais ¿mortos pela subversão¿. A memória castrense sobre a repressão responde tanto à continuidade de uma matriz narrativa sobre o passado recente, que reforça a autovaloração do exército como uma comunidade moral diferenciada da sociedade civil, quanto às transformações e inovações que vão permitindo à instituição e a seus homens posicionar-se frente ao fortalecimento da memória dos desaparecidos e ao discurso dos organismos de Direitos Humanos. Por isso, o interrogante primordial que anima esta tese é como se articulam mudança e continuidade na memória de uma instituição ¿ e dos oficiais que foram contemporâneos dos fatos- para os quais o passado é uma fonte de legitimidade e identidade, mas que, ao mesmo tempo, são energicamente questionados por uma sociedade que lhes exige respostas pelos crimes cometidos. Atender às continuidades e rupturas da memória do exército permitirá, por sua vez, dar conta de sua dimensão de futuro e, assim, determinar as tendências à elaboração (atravessamento) ou à atuação (repetição compulsiva) dos sentidos de um passado autoritário e violento que tem o exército e seus homens como um de seus principais responsáveis. Daí que esta tese propõe-se também, por um lado, a examinar em que medida, para a comunidade militar, lembrar implica também assumir ou evadir as responsabilidades morais, jurídicas e políticas sobre o desaparecimento de pessoas, e, por outro lado, compreender como se articulam os argumentos justificatórios e as estratégias políticas com as quais se busca controlar e vigiar a transmissão de sentidos sobre a ¿luta contra a subversão¿ às novas gerações. Por último, esta tese propõe-se a indagar como a ¿luta contra a subversão¿, enquanto prática e discurso, incide ao mesmo tempo em que se reapropria das significações morais dos oficiais do exército e da doutrina e práticas castrenses, assim como de seus valores, tradições e sentimentos. Para isso, busca investigar as relações entre moralidade, memória e identidade, prestando principal atenção àquilo que une os oficiais; àquilo que os obrigou ou convenceu a atuar de um ou outro modo; aos padrões de normalidade que organizam sua sociabilidade; àquilo que permitem ou proíbem, implícita ou explicitamente, seus códigos comuns; aos critérios de bem e de mal que detentam, enfim, os sentidos e práticas que estimulam e justificam a violência / Abstract: The aims of this thesis is to analyze the memory of military personel regarding illegal repression in Argentina, focusing on army¿s memory. More specifically, it attempts to recognize differences among the official memory of the army as institution, the memory of former staff from Operativo Independencia and the memory of the civil sector close to the army, highlighting their relative positions and the conflicts that underlay and inform this community of memory. The general objective is to identify the meanings and representations that, on the one hand: army and former officials produce and actualize in order to evoke and justify the so-called ¿fight against subversion¿. And on the other hand, the commemorative practices stage on by relatives of army staff, and civil organizations which supported them (such as NGO¿s), in order to pay tribute to the ¿deaths by subversion¿. The memory of repression of the army reproduces a narrative matrix on the recent past which tends to reinforce the self-perception of the army institution as a moral community isolated from civil society. But also, this memory highlights the transformations and innovations that allow the institution of the army and its personnel to take position against the increasingly stronger discourse of human rights's NGOs and the memory of relatives of disappeared people. Therefore, the main question of this thesis is how change and continuity is articulated within the memory of a institution ¿ and in the memory of the officials that have participated in the repression ¿ for whom the past is either a source of legitimacy and identity. But for whom, at the same time, this past history implies a strong criticism from public society and a demand of justice. To notice the continuities and rupture of army's memory will allow us to take account of the dimensions of future, and therefore, to determine the tendencies to elaboration () or acting (compulsive repetition) of the meanings built on a violent and authoritarian past, from which the army is one of the main responsible. In this sense, this thesis also propose on the one hand: to analyze to what extend the act of remembering for the military community implies also to assume or to evade moral, juridical, and political responsibilities over the disappearance of people. And, on the other hand to understand how are articulated different vindicative arguments and political strategies in order to control the transmission of meanings over ¿the fight against subversion¿ towards new generations. Lastly, this thesis argues that ¿the fight against subversion¿ as discourse and practice affects and gains over the moral sense of the army practices and doctrine, but also of it values, traditions and feelings. Therefore, we try to research the relations between morality, memory and identity, identifying and describing: those relations which link the army officials, those which compels or convince then to act in some way or another, the framework of normality that organizes its sociability, the internal codes of behaviour that explicitly of implicitly allow or forbid some actions, their judgement of good and evil, and the meanings and practices that encourage and justify violence / Doutorado / Doutor em Ciências Sociais

Apreensão de livros tidos como subversivos: o que os processos judiciais da Ditadura Militar revelam / -

Ana Caroline Silva de Castro 20 March 2017 (has links)
Descreve e analisa os dados sobre repressão a livros considerados subversivos entre abril de 1964 a março de 1979, no Brasil. Os dados estudados são os autos de busca e apreensão cumpridos pela polícia política e exército para confiscar obras durante a Ditadura Militar e que fizeram parte de processos judiciais que chegaram ao Superior Tribunal Militar. Cerca de 707 processos foram resgatados e reunidos pelo Projeto Brasil Nunca Mais durante a Ditadura e estão disponíveis integralmente na internet desde 2013. A pesquisa abrange todos os resultados da busca de autos de apreensão de livros confiscados contra suspeitos. Ao todo foram encontrados 323 autos de busca e apreensão em 145 processos jurídicos, representando 20% (vinte por cento) da totalidade. A pesquisa tem dois momentos. O primeiro é uma análise descritiva dos dados presentes nos autos, em que é possível saber quantos livros foram apreendidos por ano, por organizações, pelo perfil dos atingidos e por quem executou as ordens. Os autos foram analisados como um conjunto desmembrado dos processos. O segundo é a análise do auto de busca e apreensão como parte do processo jurídico. A escolha do processo analisado foi feita porque os livros apreendidos constaram como prova para condenação do réu. As constatações finais da pesquisa foram três. A primeira é que ao se analisar os dados dos autos percebeu-se que eles revelam uma fotografia da ditadura militar, sendo possível fazer uma correlação da repressão sofrida pelas diferentes organizações de resistência e o confisco dos livros. A segunda constatação é que os agentes repressivos buscavam especificamente livros que pudessem incriminar os suspeitos, sendo instruídos para identificar quais livros poderiam ser tidos como subversivos. Por fim, a terceira observação é que os livros apreendidos tinham peso relativo dentro de cada processo. Às vezes figurando apenas como anexo e em outros casos sendo usados como prova para condenação do réu. Além das contribuições apresentadas acima, a pesquisa lista os títulos dos livros apreendidos para servir de consulta e referência para próximas pesquisas sobre o tema. / It describes and analyzes data on repression of books considered subversive between April 1964 and March 1979 in Brazil. The data studied are the seizure cases carried out by the political police and the army to confiscate books during the Military Dictatorship and which were part of legal proceedings that reached the Superior Military Tribunal. Almost 707 cases have been rescued and assembled by the Brazil Never Again Project during the dictatorship and is available on the internet since 2013. The search covers all the results for the warrants against suspects in which books were confiscated. In all, 323 search and seizure cases were found in 145 legal proceedings, representing twenty percent (20%) of the totality. The research has two moments. The first is a descriptive analysis of the data present in the records, in which it is possible to know how many books were seized per year, by organizations, by the profile of those affected and by those who executed the orders. The records were analyzed as a set dismembered of the processes. The second is the analysis of the search and seizure self as part of the legal process. The choice of the process analyzed was made because the books seized were evidence for the defendant\'s conviction. The final findings of the survey were three. The first is that when analyzing the data of the records it was noticed that they reveal a photograph of the military dictatorship, being possible to make a correlation of the repression suffered by the different organizations of resistance and the confiscation of the books. The second finding is that repressive agents specifically searched for books that could incriminate suspects and were instructed to identify which books might be considered subversive. Finally, the third observation is that the seized books had relative weight within each process. Sometimes appearing only as an attachment and in other cases being used as evidence for the conviction of the defendant. In addition to the contributions presented above, the research presents the list of the books seized to serve as a reference for future research on the subject.
