Full textNär ett material stelnar sker en fasomvandling från flytande till fast fas. Begränsad diffusionunder denna fasövergång orsakar mikrosegring, vilket är ett fenomen under stelningsförloppetsom skapar sekundära faser och koncentrationsgradienter. Detta påverkar egenskaperna hosmaterialet and hur den ska behandlas under senare processteg. På grund av komplexiteten avstelningsprocessen har modellering använts för att undersöka mikrosegring. Scheil-Gulliver modellen antar att det inte sker någon diffusion i fast fas men ett utbyte avinlösta ämnen kan ha ett viktigt inflytande på stelningsförloppet. Fastän Brody-Flemingsmodellen tar hänsyn till detta så är den tveksam i sina antaganden. En ny föreslagen modell avJohn Ågren betraktar diffusionseffekter för ett multikomponent system och denna harimplementerats med hjälp av Matlab-Toolbox för Thermo-Calc. Modellen har använts för att simulera stelning för ett binärt Al-2.1Cu och ett ternärt Al-2.1-1Si system (at%) och resultaten har jämförts med Scheil-Gulliver modellen och DICTRAsimuleringar. Ågren modellen ger utmärkta resultat för det binära systemet vid högakylhastigheter. Modellen visar däremot avvikelser från DICTRA vid låga kylhastigheter samtför det ternära systemet.

Full textThis study deals with the vacuum TLP (Transient Liquid Phase) brazing of aluminum alloys applied to the manufacture of heat exchangers. Thus, the microstructure evolutions of 3003 (Al-Mn) and 4004 (Al-Si-Mg) alloys during the whole assembly process are studied. Firsty, model samples are heat treated in laboratory. The phase transformations and the solid state diffusion between the filler alloy and the base alloy are studied. The results are compared to thermodynamic predictions obtained with both Thermo-Calc and DICTRA softwares. We conclude that these tools are reliable at temperatures above 400°C. The fusion path of the filler alloy is described. It is shown that a Si enriched liquid is formed at the clad surface. On a second time, tests are carried out in industrial conditions, in order to take actual brazing parameters into account. Excessive dissolution and liquid penetration at grain boundaries are observed. The fine grained structure of the base alloy associated to a preferential diffusion at grain boundaries appear to be the main causes

Full textIn this thesis 9-12 % Cr steels, used for high-temperaturecomponents in fossil-fired power plants are considered. Thecreep strength of thees steels depend on their microstructurethat consists of a matrix of tempered lath martensite withdensely distributed precipitates. The mechanical properties arestrongly influenced by precipitates present in the matrix andthe more densely distributed they are the higher is thehardening effect. These particles nucleate, grow and coarsenduring use in power plants, leading to a degradation ofmechanical properties. In this thesis the nucleation andcoarsening behaviour of the precipitates in the Cr steels aresimulated by new models and the results are compared withtransmission electron microscopy (TEM) observations of testedmaterials.
A model of the nucleation of MX, which mainly isvanadium-nitrides, is presented. MX precipitates are assumed tonucleate on dislocations during annealing. The model takes intoaccount the full multicomponent thermodynamical behaviour ofthe system as well as the strain energy caused by a puredilatoric strain and the shape of the nucleus. The calculationsyield a critical size and shape represented by an oblatespheroid with a radius of a few nanometers and a thickness ofan atomic layer. This is in agreement with TEM observations ofsupercritical particles.
A new coarsening model, which takes into account themulticomponent effects, is presented and it has been tested ondifferent systems to validate the model.
Four different carbides, Cr7C3, Mo6C, VC and NbC, in austenitic matrix as well asγ ' in ternary Ni-base super-alloy systems (Ni-Al-Mo)were compared with measurements from literature.
TiC-particles in austenitic stainless steel, ASTM 316Ti,were considered. The simulations were performed taking intoaccount iron and 7 alloying elements. The measurements wereperformed with TEM on samples that had been heat-treated at900° C.
MX and M23C6in a 9 % Cr steel were investigated with energyfiltering transmission electron microscopy (EFTEM) andcompared with simulations. The used samples had been heattreated for various periods of time at 600 and 650° Cfor up to 26 000 h.
The agreement of the simulations with the experiments wasgood in all cases when reasonable values of the interfacialenergy, the only adjustable parameter, were chosen.
Coarsening simulations were also performed to investigatethe influence of changes in composition on the coarsening rate.For MX, in a 9 % Cr steel, the coarsening rate is almostindependent of the V/Nb ratio but highly dependent on theN-content. Also the effect on the coarsening rate for M23C6by adding Co to a Cr steel was investigated bysimulation. Co is known to increase the resistance totempering. The results show that a final average radius of thecarbides after 30 000 h at 600° C decreases with 30 % witha Co addition of 10 mass %.

Full textCette dissertation développe un modèle théorique du processus créatif propre au documentaire. Il propose un rôle fondamental pour la métaphore, qui préserverait l'intégrité émotionnelle de l'expression artistique. La première partie est dévouée à l'examen du rôle de la métaphore dans la littérature, selon la perspective du philosophe Giambattista Vico. Une application à la production artistique du modèle Vichien du développement culturel révèle le fondement imaginaire de l'expression artistique, ainsi qu'une dynamique par le biais de laquelle la subjectivité de l'artiste est communiquée directement à son public. La deuxième partie du texte applique ce modèle au documentaire. L'analyse de ses principes fondamentaux entreprise par John Grierson s'avère signifiante et dévoile un fondement imaginaire au documentaire, évocateur de la dynamique élaborée dans la première partie du texte. L'éditorialisation importante en documentaire suggère qu'il resemblerait à la littérature, plutôt qu'au journalisme auquel il est si souvent comparé. Une étude brève du développement du cinéma vérité et de son usage particulier de la technologie afin de réduire le besoin de traduction envers l'objectif complète et renforce cette analyse. La dernière partie du texte applique le modèle développé par l'auteur dans les premières parties à la production du documentaire SALT, produit par l'Office National du Film en 2000.
Lannoy, Marie. "Les "Obiter dicta" du Conseil d'État statuant au contentieux." Thesis, Paris 1, 2014. http://www.theses.fr/2014PA010269.
Full textThe notion of obiter dictum indicates a comment made «by the way» or «in passing», usually by a Common Law judge. In this study, obiter dicta refer to incidental statements expressed by the French Council of State when it gives a ruling or delivers a judicial opinion. Obiter dicta can be regarded as departures from the efficient tradition of stating the minimum essential to dispose of the matter or as infringements of the prohibition against passing judgment outside the issues raised by the opposing parties. When the Council of State delivers an obiter dictum, it makes a statement of law that is not essential to the judicial outcome. Obiter dicta fulfil two functions. They enable the Council of State to express generalisations independent of particular judgments and thereby to produce an abstract system of precedent. As a consequence, the decisions of the Council of State produce a general jurisprudence that is no longer limited to the facts of particular cases. Obiter dicta also enable the Council of State to justify and explain its judgments in concrete terms, with the result that they contribute to the elucidation and enforcement of its decisions.We can conclude, therefore, that obiter dicta supply the potential for superior general jurisprudence and for improved particular judgment. In short, that obiter dicta reveal a new way for the French Council of State to dispense justice

Full textLe gène DICER1, qui code pour la protéine du même nom, est essentiel pour la production de microARNs. Ceux-ci étant aussi courts que 20 nucléotides, modifient l'expression des gènes ciblés en phase de posttranscription en se liant directement aux mARNs et en conséquences affectant leur translation. Présentement, on estime que l'expression de 30 à 70% de tous les gènes qui codent pour une protéine sont modifiés par des microARNs. Récemment, 60 à 70% de tous les cas de blastomes pleuropulmonaires, tumeurs pulmonaires infantiles, ont été associés à des mutations germinales de DICER1. Nous avons découvert que des mutations germinales de DICER1 sont impliquées dans un tableau de maladies en identifiant des mutations dans 60 personnes provenant de 15 familles différentes, ayant 7 phénotypes de maladies différents. Ceux-ci incluent des cas de blastomes pleuropulmonaires, de néphromes kystiques – des tumeurs rénales bénignes, et des tumeurs de Wilms – une forme maligne de la néphrome kystique. Par ailleurs, nous avons identifié des mutations de DICER1 dans plusieurs familles affectées par des tumeurs de cellules Sertoli-Leydig (TCSL) – un cancer rare de l'ovaire produisant de l'androgen, et la goitre multinodulaire (GMN) - une hyperplasie relativement fréquente de la thyroïde. Nous avons demontré que DICER1 est le lien entre TCSL et GMN ce qui a été suggéré en 1974 par Fraumeni et ses collegues. Nous avons également identifié que le gène MNG1 au locus 14q32 est DICER1. Cette région était découverte en 1997 dans plusieurs familles avec GMN. Nous avons élargi le phénotype des maladies associées avec DICER1, et ajouté le rhabdomyosarcome embryonnaire cervical à la liste. Quoique DICER1 est un gène suppresseur de tumeur, nous n'avons pas trouvé une preuve de la perte d'hétérozygotie dans l'ADN des tumeurs testées. Ceci est validé par des preuves récentes que DICER1 est un gène suppresseur de tumeur à caractère unique. L'expression des microARNs dans les cellules cancéreuses était significativement différente de celui observée dans les cellules normales. Nous avons démontré que les mutations de DICER1 sont associées à des maladies variées, une découverte pas très surprenante considérant son rôle de grande envergure dans la production de microARNs. Ces développements peuvent être utilisés dans de futurs efforts thérapeutiques et pour le dépistage des familles avec des maladies semblables.

Full textThis research aims to identify and analyze the use of the biblical interpretation method named "proof-text method" among Seventh-day Adventists (1986-2013) in the literature about the lifestyle of young Adventist, and its influence on the hermeneutics of Adventist youth. The first chapter is a historical description of the "proof-text method", its origins and presence in Christianity in general and in particular in Adventism. It also makes a distinction between this method and other hermeneutical resources used in Adventist theology, and a brief review of the method in the light of adventist official hermeneutical principles. The second chapter assesses the presence of the "proof-text method" in guidance materials on the lifestyle of young Adventist, produced and published by the Adventist Church Seventh Day in the 1986-2013 period. Finally, the third chapter analyzes the influence of the use of the "proof-text method" in spirituality and hermeneutical training of young Adventists, using the theory of "Stages of Faith" proposed by James Fowler.

Resumo: Neste trabalho, estudamos e traduzimos integralmente uma obra da literatura latina tardia conhecida como Ephemeris belli Troiani Dictys Cretensis (Diário da Guerra de Troia ), anônima e datável do século IV d. C. Ephemeris relata os eventos da Guerra de Troia do ponto de vista de um narrador em primeira pessoa que se apresenta como um soldado cretense de nome Díctis, alistado na tropa do comandante grego Idomeneu. A narração do prélio entre gregos e troianos, conhecida em literatura primordialmente pela leitura da Ilíada, de Homero, reveste se em Ephemeris de uma intenção racionalista ao diminuir os heróis à condição humana regular, ao diminuir a atuação dos deuses e ao estruturar a narrativa de forma lógica e cronológica. Composta de seis capítulos, precedidos por uma epístola e um prólogo, a obra é uma versão para o latim de um texto do século II originalmente em grego, o qual se encontra hoje fragmen tado. Ephemeris ganha importância no tocante à conservação do mito troiano, pois no Ocidente latino, desde o século I a. C. C., a história da Guerra de Troia era cada vez menos conhecida por intermédio dos poemas homérico e da literatura grega em geral em decorrência de uma precariedade na difusão do idioma grego por entre a elite romana. Acrescente se a esse fator a posterior e crescente pressão da Igreja que rechaçava os deuses não cristãos que habitavam a narrativa homérica. Desse modo, outras obras, compostas em latim, assumiram a transmissão da história troiana que nos...
Abstract: In this work, we study and translate integrally a late Latin work known as Ephemeris belli Troiani (Diary of the War of Troy ), anonymous and dating from the fourth century AD. Ephemeris reports the events of the Trojan War from the viewpoint of a first person narrator who presents himself as a Cretan soldier named Díctis, enlisted in the troop of the Greek com mander Idomeneu. The account of the battle between Greeks and Trojans, known in literature primarily by the reading of the Homer's Iliad, is dressed in Ephemeris of a rationalistic intention by diminishing the heroes to the regular human condition, by decr easing the performance of the gods and structuring the narrative logically and chronologically. Composed of six chapters, preceded by an epistle and a prologue, the work is a Latin version of a text of second century, written originally in Greek, which is now fragmented. Ephemeris gains importance with regard to the conservation of the Trojan myth. In the Latin West, since the first century BC, the story of Trojan War was less known through Homeric poems and Greek literature in general because of a precario usness in diffusion of the Greek language among the Roman elite. Add to this factor the later and growing pressure of the Church that rejected the polytheistic gods who inhabited the Homeric narrative. In this way other works composed in Latin assumed the transmission of the Trojan story that offered the Homeric epic. Of particular note is Ephemeris, which ...
Riassunto: In questo lavoro, studiamo e traduciamo integralmente uma opera latina conosciuta come Ephemeris belli Troiani (Diario della guerra di Troia ), anonima e risalente al secolo IV d. C. Ephemeris riporta gli eventi della guerra di Troia dal punto di vista di un narratore in prima persona che si presenta come un soldato chiamato Ditti Cretese, arruolato nell'esercito del comandante greco Idomeneo. La narrazion e del combattimento tra Greci e Troiani, nota in letteratura soprattutto per la lettura dela Iliade di Omero, si presenta in Ephemeris con un'intenzione razionalista poiché diminuire gli eroi alla condizione umana normale, ridurre il ruolo dele divinità e strutturare la narrazione in modo logico e cronologico. Composto da sei capitoli, preceduti da una lettera e un prologo, il libro è una versione latina di un testo greco del secolo II, che ora si conosce in frammenti. Ephemeris guadagni importanza per quan to riguarda la conservazione del mito troiano, perché nell'Occidente latino, dal primo secolo, la storia della guerra di Troia era sempre meno conosciuto attraverso i poemi omerici e l a letteratura greca in generale, a causa della bassa diffusione della li ngua greca tra l'elite romana. D'alt ra parte, l'ulteriore e crescente pressione della Chiesa respingeva le divinità non cristiane che abitavano la narrazione omerica. In questo modo, altre opere, composte in latino, presero la trasmissione della storia di Troia offerta dall'epopea omerica. Si distingue tra queste ...

Full textThe obiter dictum is a little known figure of the civil case-law of the Court of cassation. Yet, its presence amongst cases is regularly acknowledged, and even questioned by legal scholars. Better known by supranational courts or the institutions of superior courts of Public Law, its existence remains unsettling. It was, thus, necessary to better understand the reservations towards this object, and then observe what makes the specificity of the obiter dicta of the Court of cassation as well as to try to identify this phenomena. Once the consciousness of the existence and the specificities of this process had been acquired, its notion could be studied. The obiter dictum of the Court of cassation had to be distinguished from its counterpart that remains inherent and indispensable to the Common Law. Although the designation is identical, the reality they encompass varies. After having, also, separated the obiter dictum from other elements of the discourse of the Court of cassation, a definition was proposed by combinning two criteria : the insertion of an utterance within the decision and its extrinsic nature regarding the decisional field. The study of the status of the obiter dictum revealed its true nature of a tool. The practice of this instrument by the cassation judge needed to be detailed, whilst equally taking into account the contemporary reflections surrounding the reform of the Court of cassation in order to consider what would become of the obiter dictum. The observation of its functions allowed us to shine a light on its anticipatory role. If the obiter dictum seems to be a useful instrument serving the jurisdictional missions of the cassation judge, its virtues are not without limits. It cannot be thought of as a systematic remedy to the negative effects of courts overruling. A precious tool in the hands of the cassation judge, the obiter dictum appears, within the context of the questions regarding the opportunity and modalities of a reform of the Court of cassation, as an instrument searching for/in search of equilibrium

Full textUne première partie de l’essai s’attache à identifier la terminologie latine du mensonge. La tradition nous a légué les définitions et acceptions rigoureuses retenues par saint Augustin, sans égard à une subtile distinction qu’Aulu-Gelle avait puisée chez Nigidius Figulus :'mentiri' et 'mendacium' empruntent leurs étymologies distinctes respectivement à la pensée (racine *men-) et à l’erreur ('mendum' ou 'menda'), mais l’absence de parenté étymologique n’a guère affecté une étroite alliance sémantique dans l’usage, et ce aussi loin que remontent nos sources, en l’espèce l’œuvre du dramaturge Plaute, œuvre où abondent ces deux mots qu’aucun écrit antérieur n’atteste.
La deuxième partie de l’essai confronte l’alliance sémantique des deux mots à leur absence dans les textes conservés du droit archaïque, en vue de tenter d’expliquer leur rareté dans les textes ultérieurs. Une œuvre fait l’objet d’un examen approfondi, en raison de la remarquable représentativité de la mentalité d’âge républicain qui doit lui être reconnue :la comédie du Pseudolus de Plaute. La valeur de témoignage de ce texte ne peut cependant être mise en avant qu’en écartant deux préventions :1) l’inattendue irrigation du texte comique par la doctrine épicurienne – la canonique (ou discipline du raisonnement) bien plus que l’éthique – n’y réduit pas la thématique du mensonge à une parodie de la notion du clinamen, notion alors anachronique si l’on s’en tient aux seuls textes attribués à Epicure ;2) il convient de ne prêter au dramaturge aucune intention subversive comparable à celle qui avait peu auparavant valu la censure au poète Naevius. L’analyse du texte, dans sa perspective historique éclairée par les récits de Polybe et de Tite-Live, conduit à relier l’hommage de Plaute aux facultés intellectuelles de discernement qu’il prête aux Romains – alors à l’apogée de leur condition juridique de 'ciuis/miles' ou citoyen/légionnaire – à la promotion politique des vertus du raisonnement et de la circonspection, promotion symbolisée par la dédicace d’un temple à Mens au cours de la deuxième guerre punique. Le droit civil – au sens de droit objectif propre à la cité – apparaît alors, dans la rigueur de son formalisme originel, comme le corollaire, dans les rapports juridiques entre citoyens, de la discipline imposée au légionnaire dans sa confrontation à l’ennemi extérieur ('hostis/inimicus') :un impératif civique d’exercice constant de la vigilance et de la 'prudentia'. Aussi n’est-ce pas la faute morale du menteur qui doit être juridiquement sanctionnée, mais bien la coupable imprudence de l’interlocuteur qui verse dans l’erreur et succombe à l’'animus fallendi' du menteur. Encore l’étymologie retrouve-t-elle ses droits lorsque s’opère une distinction entre, d’une part, la neutralité du substantif 'mendacium' – son aspect ‘métallique’ d’arme susceptible d’être maniée en bien ou en mal selon la qualité civique de l’utilisateur – et, d’autre part, la stigmatisation du verbe déponent de sens médio-passif 'mentiri'. Ce verbe, immédiatement dérivé de la racine *men-, aurait pu ne viser que le fait de ‘penser’ s’il n’avait, comme l’analysera Varron, été réservé par l’usage qu’à une pensée strictement égoïste, excluant comme telle tout partage, donc à l’encontre des devoirs inhérents à la participation aux débats dans les assemblées publiques caractéristiques de la vie républicaine :être animé d’une pensée susceptible de partage se dit 'cogitare'.
La troisième partie de l’essai s’attache à décrire l’évolution de la mentalité héritée de la deuxième guerre punique à la mesure de l’extension du domaine de l’ancien droit civil à une société cosmopolite, au sein de laquelle les attentes placées dans la figure emblématique du citoyen romain sincère doivent composer avec les nécessités nouvelles de relations juridiques plus complexes, relations que les vertus civiques prêtées au citoyen/légionnaire ne peuvent plus suffire à régir. Evolutions contrastées du 'ius publicum' et du 'ius priuatum' :tandis que, sur la voie du Principat, les rapports de force politiques cantonnent le devoir de sincérité à une morale personnelle bien aléatoire au cours des conflits qui altèrent le dernier siècle de la République, le droit privé s’enrichit du 'ius gentium' pour s’efforcer, dans les 'iudicia bonae fidei', de substituer à la vigilance formaliste une conscience substantielle des devoirs de sincérité des cocontractants. C’est toutefois en vain que Cicéron suggère de transposer à la scène politique l’éthique du droit civil, ou que Virgile (en particulier dans un épisode-clé du deuxième livre de l’Enéide, manifestement inspiré aussi par la canonique épicurienne) tente de ressusciter une éthique collective de la vigilance face au mensonge. Etrangers donc au droit public de l’Empire, les termes mendacium et mentiri n’apparaissent qu’en ordre dispersé dans un nombre restreint de notices du Corpus iuris ciuilis et, faute d’y être érigés en termes techniques, ne participent que de transpositions ponctuelles aux rapports de droit civil de sanctions inspirées par un devoir de sincérité jadis enraciné dans des notions républicaines de la responsabilité personnelle et de la solidarité.
Aux termes extrêmes de nos sources latines antiques, le mensonge, dans sa dimension élémentaire d’affirmation délibérément trompeuse, a été entendu de deux façons apparemment diamétralement opposées :d’un impératif républicain de sanction de la crédulité à la condamnation uniformément rigoureuse prononcée par saint Augustin. Cette opposition se mue cependant en synthèse si l’on veut bien considérer que la conception augustinienne tend à conférer la dimension métaphysique de la Cité de Dieu au devoir romain de sincérité autrefois et autrement promu dans les limites de la seule cité républicaine. Entre deux conceptions absolument fondées sur la norme éthique, la norme juridique romaine, seulement appelée à régir l’altérité avec réalisme, n’a traité qu’avec une parcimonieuse prudence de cette perversion de la pensée qu’est le mensonge.

Full textDicer plays a central role in RNA interference pathways by cleaving double-stranded RNAs (dsRNAs) to produce small regulatory RNAs. Human Dicer can process long double-stranded and hairpin precursor RNAs to yield short interfering RNAs (siRNAs) or microRNAs (miRNAs), respectively. In humans, Argonaute2 (AGO2) assembles with the guide RNA-generating enzyme Dicer and either the RNA-binding protein TRBP or PACT to form a RISC-loading complex (RLC), which is necessary for efficient transfer of nascent siRNAs from Dicer to AGO2. Here, I have used electron microscopy and single particle analysis of human Dicer-RNA complexes and the RLC to gain insight into the structural basis for human Dicer's substrate preference and RISC-loading. My studies show that Dicer traps pre-siRNAs in a non-productive conformation, while interactions of Dicer with pre-miRNAs and dsRNA binding proteins induce structural changes in the enzyme that enable productive substrate recognition in the central catalytic channel. The RLC Dicer's N-terminal DExH/D domain, located in a short base branch, interacts with TRBP, whereas its C-terminal catalytic domains in the main body are proximal to AGO2. A model generated by docking the available atomic structures of Dicer and Argonaute homologs into the RLC reconstruction suggests a mechanism for siRNA transfer from Dicer to AGO2.

Full textDictée and Solfége are types of musical exercises and two of the most difficult in teaching of music and source of disappointment for students. Their errors can be revealing. The aim of the research is to observe, describe and analyze errors that were realized during the transcription of tonal and modal melodies (western European tonal music, Greek popular and folkloric music). These also constitute indications and the means to analyze cerebral procedures that relate with the learning of music and allow us to discover the reasons that have to do with the recognition of musical notes, intervals, degrees, cadences and rhythmical values that cause difficulties and errors. The 6 students, our representative statistical sample, are examined in two different types of teaching (typical και Kodály) into a special cultural environment. Indeed, the interpretative analysis proves the indisputable influence of culture and musical education

Full textLa poliadenilación citoplasmática es un mecanismo de control de la traducción extendido a lo largo de la escala animal. En vertebrados, este mecanismo requiere dos secuencias en el extremo 3’ no traducido (UTR) del mRNA, el elemento de poliadenilación citoplasmática rico en uridinas (CPE) y el hexanucleótido de poliadenilación AAUAAA (HN). En embriones tempranos de Drosophila, la poliadenilación de Toll, sin embargo, ocurre independientemente de estas secuencias, y requiere al menos dos factores: Dicer-2, una proteína previamente implicada en interferencia de RNA (RNAi), y la poly(A) polimerasa Wispy. Para entender esta nueva función de Dicer-2 en poliadenilación citoplasmática y traducción, nos propusimos diseccionar los elementos en el extremo 3’ UTR de Toll relevantes para este mecanismo de poliadenilación no canónica, así como identificar proteínas y mRNAs que interaccionan con Dicer-2 a gran escala. Nuestros resultados indican que el extremo 3’ UTR de Toll contiene varias secuencias implicadas en poliadenilación, y que el mecanismo no canónico es dominante en embriones tempranos, probablemente porque los elementos canónicos (CPE y HN) se encuentran activamente reprimidos. El estudio del interactoma de Dicer-2, realizado por purificación por afinidad e identificación por espectrometría de masas, reveló numerosas proteínas que no están implicadas en RNAi. Entre ellas, encontramos factores previamente relacionados con control de la longitud del poly(A) o con interacción con PABP y traducción, sugiriendo que estos factores podrían actuar x como co-factores de Dicer-2 en poliadenilación citoplasmática. Análisis de mRNA targets mediante RIP-Seq reveló multiples tránscritos que previamente fueron identificados como targets de Wispy. Estos resultados sugieren una función extendida de Dicer-2 en poliadenilación citoplasmática, y establecen una base sólida para investigaciones futuras.

O mecanismo de RNA de interferência (RNAi) é um sistema pós-transcricional de silenciamento gênico com ampla distribuição nos organismos eucariotos. Os pequenos RNA (siRNA e miRNA) são considerados moléculas chaves nesse mecanismo, os quais são gerados pela proteína Dicer. A presença desse sistema parece não seguir um padrão de distribuição filogenético e a sua evolução ainda não foi compreendida. Entre os protozoários, o mecanismo de RNAi está muito bem caracterizado em Trypanosoma brucei, entretanto é ausente em Trypanosoma cruzi e em muitas espécies de Leishmania. O Trypanosoma rangeli não possui vários componentes da maquinaria de RNAi, tornando-a não funcional. Entretanto, o gene que codifica para a Dicer- Like2 (DCL2) foi encontrado completo em seu genoma, enquanto os demais genes codificantes para as outras proteínas da maquinaria estão truncados (pseudogenes). No presente estudo realizamos a caracterização do gene DCL2 de T. rangeli (TrDCL2), o qual apresentou-se como cópia única no genoma do parasito, possuindo uma janela aberta de leitura com 2.667 pb que codifica para uma proteína de 889 aminoácidos (±100 kDa). Foram reveladas diferenças nas sequências aminoacídicas da TrDCL2 entre as cepas KP1(+) e KP1(-) de T. rangeli e devido uma mudança na fase de leitura não é possível identificar os domínios RNAse III nas cepas KP1(-). O gene TrDCL2 é transcrito nas cepas KP1(+), sendo que os níveis de mRNA não apresentam alterações significativas durante o processo de diferenciação celular in vitro do parasito. Visando a avaliação da atividade enzimática e análise da presença e níveis proteicos, realizamos a expressão heteróloga de dois fragmentos e da proteína TrDCL2 inteira. Um dos fragmentos foi utilizado para a produção de um antissoro policlonal anti-TrDCL2. Este antissoro reconheceu uma proteína do tamanho esperado (±100 kDa) nos extratos proteicos totais das formas epimastigotas e tripomastigotas de T. rangeli. Os ensaios de imunofluorescência indireta, utilizando o mesmo antissoro, revelaram uma distribuição difusa da proteína pelo citoplasma de ambas as formas do parasito. A TrDCL2 é expressa em algumas cepas do T. rangeli, entretanto a determinação do seu papel biológico neste parasito ainda permanece a ser elucidada.
Abstract : The interference RNA mechanism (RNAi) is a system of post-transcriptional gene silencing with wide distribution in the eukaryotes. Small RNA (siRNA e miRNA) are considered key molecules in this mechanism, which are generated by Dicer protein. The presence of this system seems not follow a pattern of phylogenetic distribution and its evolution is still not understood. Between trypanosomatids, the RNAi mechanism is well described in Trypanosoma brucei, but is absent in Trypanosoma cruzi and some Leishmania species. Trypanosoma rangeli does not have many components of RNAi machinery, making it not functional. However, the Dicer-Like2 (DCL2) coding gene was fully encountered in its genome, while the other genes of this machinery are truncated (pseudogenes). In the present study, we have realized the characterization of DLC2 gene of T. rangeli (TrDCL2), which presented a single copy in the parasite genome, having an open reading frame with 2.667 bp that encodes a protein with 889 amino acids (±100 kDa). Differences in aminoacidic sequences were revealed between strains KP1(+) and KP1(-) of T. rangeli and due to a change in the reading phase it was not possible to identify RNAse III domains in the KP1(-) strains. TrDCL2 gene is transcripted in the KP1(+), the mRNA levels do not show significant alterations during the process of cellular differentiation in vitro. Aiming the evaluation of the enzymatic activity and the analysis of the presence of the protein and its levels, we realized the heterologous expression of two fragments and the whole protein TrDCL2. One of the fragments was used to produce a polyclonal antiserum anti-TrDCL2. This antiserum recognized a protein with the expected size (±100 kDa) in the total protein extracts of the epimastigotes and trypomastigotes of T. rangeli. Imunofluorescence assays, using the same antiserum, revealed a diffuse distribution of the protein in the cytoplasm in both forms of the parasite. The TrDCL2 is expressed in some strains of T. rangeli, but the determination of its biological role in this parasite still needs to be elucidated.
