Hebras, Jade. "Caractérisation moléculaire du petit ARN nucléolaire SNORD115 : un rôle dans la régulation de l'expression et de la fonction du récepteur à la sérotonine 5-HT2C ?" Thesis, Toulouse 3, 2020. http://www.theses.fr/2020TOU30209.
The nucleolus of mammalian cells contains hundreds of box C/D small nucleolar RNAs (SNORDs). Majority of them, guide sequence-specific 2'-O ribose methylations into ribosomal RNA (rRNA). Some of them facilitate RNA folding and cleavages of ribosomal RNA precursors or guide ribose methylations into spliceosomal small nuclear RNA U6. Recent studies propose that some SNORD could target other transcripts, possibly messenger RNA as suggested by the brain-specific SNORD115. SNORD115 is processed from tandemly repeated genes embedded in the imprinted SNURF-SNRPN domain. Defects in gene expression at this domain are causally linked to rare disease: the Prader-Willi Syndrome (PWS). Excitingly, SNORD115 displays an extensive region of complementary to a brain-specific mRNA encoding the serotonin receptor 5-HT2C. SNORD115 could influence 5-HT2C signaling by fine-tuning alternative splicing or A to I RNA editing of 5-HT2C pre-mRNA. Reduced 5-HT2C receptor activity could contribute to impaired emotional response and/or compulsive overeating that characterized the syndrome. My work was to test this hypothesis using a CRISPR/Cas9-mediated SNORD115 knockout mouse model. My results show that loss of SNORD115 expression, in vivo, does not alter the post-transcriptional regulation of 5-HT2C pre-mRNA processing. Others results from the team do not reveal any defects in anxio-depressive phenotypes and eating behaviour. Our study questions the regulatory roles of SNORD115 in brain functions and behavioural disturbance associated with PWS. On other hand, I have studied ribose methylation sites in rRNA from mouse tissues. This work was included in emerging field of the specialized ribosome hypothesis which suggests heterogeneity in ribosomes may impact activity of ribosomes. Our results show significant changes at few discrete set of sites, especially in rRNA from developing tissues. Also, rRNA from developing tissues is globally less methylated than rRNA from adult tissues. We focus on LSU-Gm4593 site because this position is specifically methylated only during development and hardly ever detected in adult tissues. Methylation at LSU-G4593 is guided by SNORD78. We propose that the expression levels of SNORD78 during development appeared to be regulated by alternative splicing of the host-gene and to correlate with the methylation level of its target site at LSU-G4593. We've used a human cell line (HEK293T) inactivated for the SNORD78 gene in order to understand the functionally role of the corresponding ribose methylation. Our work did not demonstrate any overt cellular phenotypes, even though translation fidelity and the precise function of LSU-Gm4593 remains unknown
Mellot, Jean-Dominique. "Dynamisme provincial et centralisme parisien : l'édition rouennaise et ses marchés (vers 1600 - vers 1730)." Paris 1, 1992. http://www.theses.fr/1992PA010612.
According to a classical point of view, after the 16th century, the provincial publishing business would have continuously regressed because of the centralization process, and lost the initiative to the advantage of a Parisian monopoly. The case of Rouen, second most important city of the kingdom in the middle of the 17th, shows however that this century particularly favoured the provincial publishers. The continual increase of the french market (success of vernacular literature, rise of the religious book, etc. ) Did not only benefit to the book professions in Paris. From the very late 16th and during the two thirds of the following century, Rouen asserts itself as the first or second most important publishing center in the provinces. Its assets ? A particularly dynamic and closely knit community of printers and booksellers, family and craft structures which allow publishers to keep costs at a minimum, the proximity of Paris, a considerable local market, and relative freedom to reprint which favours exportation. So, until about 1670, Rouen can openly play the role of a strong competitor for the capital. But, from this period, the concentration and control policy, the liberalities (privileges and "continuations") granted exclusively to Parisian publishers begin to compromise the Rouen activity. As the "regime des privileges" is extended to the whole book production, as the censorial process is systematized, in the very beginning of the 18th century, the Rouen publishing business is condemned either to illegality or to ruin. Choosing the first solution, it will satisfy the expectations of the new markets (in particular, popular and prohibited books) and finally lead the central power to the "tolerance of powerlessness"

Brunel, Thierry. ""Les entretiens solitaires" de Georges de Brébeuf : édition critique." Lyon 3, 2009. https://scd-resnum.univ-lyon3.fr/in/theses/2009_in_brunel_t.pdf.
Famous in the 1650s, for his gallant and heroic verses, the poet native from Normandy, Georges de Brébeuf, publishes the Solitary Conversations or the Prayers and the meditations in verse French in 1660. Although he belongs to the Jesuit culture, the Solitary Conversations attest in poetry an augustinian vein out of Port-Royal poetry, due to the influence of the Norman spiritual environment and the preponderant part of augustinian oratorians. Brébeuf succeeded in a double synthesis. He made coincide, in the poetics of meditation, a large part of the protocol and the mental processes of Jesuit spirituality with an austere and pessimistic augustinian content, drawn both from the Confessions of Augustine and the augustinian tradition. Moreover, Brébeuf managed to reconcile the principles of worldly aesthetics, with the denunciation of vanities of the world and the will to lead his reader, through a fluctuating and unstable subject of enunciation, to penance and conversion. The Solitary Conversations can really be considered as a literary Vanity which uses some rhetorical strategies to move the reader and to break the bastion of his self-esteem. Once the intimate space became empty of sinner’s “ego”, the divine Grace can fill back this pure capacity. The Solitary Conversations, between baroque and classicism, may have been, for the readers, the occasion of a pious entertainment and, by alternating the songs of the Grace and the Nothingness, may have prepared their conversion, beyond the text. But that rests on a Mystery of God

Lopez, Obando Mauricio. "Etude du rôle des protéines de la famille PPR doublement adressées à la mitochondrie et au plaste dans l'édition de l'ARN chez Arabidopsis thaliana." Thesis, Evry-Val d'Essonne, 2014. http://www.theses.fr/2014EVRY0009/document.
Mitochondrial and plastid are essential organelles within the plant cell. The process of RNA metabolism such as transcription, post-transcriptional modifications as splicing and editing and translation are very similar in these organelles. Among the actors of these processes, the PentatricoPeptide Repeat (PPR) proteins have an important role. In this research, firstly, I assessed the dual localisation of PPR proteins to mitochondria and chloroplasts organelles in Arabidopsis thaliana. The synthesis of all the data, those produced during my thesis, those available in the literature and those contained in the proteomic databases have revealed that between the 473 members of the PPR family in A. thaliana, 9 % are potentially dually localaized in both organelles. A part of this thesis analyzes and discusses the evolutionary and functional implications of this class of localisation in the PPR family. In order to understand the activity of PPR proteins in both organelles, I focused my work in the functional analysis on four PPR proteins (OTP90, OTP91, OTP100 and DYW2 ) potentially involved in the editing process. Although functional characterization of these four proteins has not been fully completed, in this thesis, I was able to demonstrate that the OTP90 and DYW2 proteins act on editing of organelles transcripts and particularly I found that the DYW2 protein participates in the editing of chloroplast and mitochondrial transcripts. Thus, the results of my research are in concordance to recent data obtained by the world, showing that PPR proteins have complex roles influencing several transcripts and/or processes in the RNA metabolism of organelles

Bragantini-Maillard, Nathalie. "Melyador de Jean Froissart, roman en vers de la fin du XIVe siècle : édition critique et commentaire (v. 1-14743)." Paris 4, 2007. http://www.theses.fr/2007PA040154.
The new critical edition of the first 14,743 verses of Jean Froissart’s Melyador relies upon the unique almost complete manuscript Paris, BnF, fr. 12557. Redrafted around 1381 with the collaboration of its patron, Wenceslas de Luxembourg, duke of Brabant, who inserted eleven ballades, sixteen virelays and fifty-two rondeaux, this latter Arthurian romance counting more than 30,770 octosyllables recounts the advent of four love stories, that, while punctuated with jousts and tournaments to which gives rise the organization of a quest, inspire various lyrical songs. Tinged with Picard and Walloon features, it offers an idea of the linguistic resources and maturity of its author, the work of which is in line with the linguistic renewal movement and literary thinking of the fourteenth century. Appropriating multiple literary genres in a masterly way by means of renewal or comic diversion, Froissart gives us to read a complex work, merrily aware of its power, but also of its fictional status. The introduction presents the author and the manuscript and editing traditions, discusses the versions and their dating, studies the language and proposes an analysis and a literary comment. The edition comprises endnotes, comprehensive glossary and index, as well as a thorough bibliography. It sets out to deliver an established text following the modern principles of editing and respectful toward the remarkable features of the manuscript that conveys it to us

Fauré, Benjamin. "Vers une histoire de l'alchimie médiévale en Occident, du domaine de la scolastique à celui du pouvoir temporel, avec une édition critique de la Disputatio attribuée à Michel Scot." Toulouse 2, 2006. http://www.theses.fr/2006TOU20017.
The treatise of Disputatio Scoti is an additional example of an erudite alchemy in close conformity with the Scholastic philosophy. To better understand this text, we must examine the standing of alchemy within Western medieval society and present a coherent and detailed overview of this issue (existing works on this theme are often too synthetic or inconsistent). My study therefore focuses on the links between alchemy and the Scholastic philosophy as viewed by scholars and philosophers. After presenting the historical and economic context in which the questions for producing gold artificially and discovering a long-life elixir arose, I highlight the known connections between the lay and ecclesiastic princes and alchemy. The third part of my thesis deals with a comment and a critical edition of the Disputatio, wrongly ascribed to Michel Scot
Provost, Audrey. "Les usages du luxe : formes et enjeux des publications sur le luxe en France dans la seconde moitié du dix-huitième siècle (vers 1760-1789)." Paris 4, 2002. http://www.theses.fr/2002PA040216.
Between 1760 and 1789, luxury became a topic of written publication. Many authors strategically chose to publish on luxury and attempted to define its nature and meaning. This intensive investment proved ambitious writers with a way to advance through the Republic of Letters. At stake in the debate over the meanings of "luxury" was not only the linguistic competence and literary talent of the authors concerned, but also their authority to establish common values, an authority which competed with the power of the monarchy to fix the terms of political discourse
Portet, Pierre.

Toulouse 2, 1995. http://www.theses.fr/1995TOU20060.
The land surveyor bertrand boysset was born at arles crica 1355 and he wrote two technicals treatises dealing with land surveying and bounding. These writings remain the first known for the western middle ages. They are of low mathematical level and they show a great concern for precision in land measuring. They also show in a very realistic way the pratices of land surveying in the early 15th century

The aim of this study is double: bringing to know a not yet edited text and this through the most faithful possible transcription of a manuscript selected as an authentic historic witness to the plan of the literary history but also the given state of language. The systematic transcription of the text thus serves to bring to light certain linguistic practices of the scribe. On the one hand; we observe graphic uses which exceed the phonogrammic function, recognized originally as essential, to achieve a morphogrammic use emphasized by specific written forms which crea the recurrence of grammatical and lexical morphemes ; on the other hand, micro-systems appear through the original use of sequences and graphic segmentations which, in this manuscript, proceed very often from a reflexive movement. These observations are leading to think that a "grammar" of French goes back up beyond the XVth century. We would thus reveal in the case of this scribe an onset of grammatical reflection on the “writing procedures” of his manuscript which would announce the “theorization of French”, characteristic of the XVth and especially of XVIth centuries. While it is situated well before any form of standard prescriptive, this manuscript, which beside more traditional linguistic practices (XIIth-XIIIth centuries) sets up a certain number of micro-systems in the functioning of written forms as well as in that of the " graphic sequences ", announces nevertheless some of the principles which will lead to the normed codification of French. From this point of view, this manuscript allows to reveal the existence of a continuum in the history of the handwritten practices of French, registering this study in the perspectives of contemporary research on the French Diachrony

This thesis is attached to a particular part of Gerbert of Metz, last part of the original Loherain cycle, the conclusion of the story (from the flight of Fromondin, the last of the Bordelais, until his death). This edition includes a detailed description and a comparative study of all the manuscripts available for this passage (twelve complete manuscripts: ABCDEJMNPRSV, and three amputees of the late IL1Q), a literary study attempting to analyze the originality of this conclusion with a narrative, stylistic and historical point of view, a linguistic analysis as well as a glossary, an index of proper nouns. The edition of the texts is presented in a semi-synoptic form in order to allow a comparative reading of the different families of manuscripts considered for the conclusion. The interest of this thesis is to propose new elements in the knowledge of the rich manuscript tradition of the Geste des Loherains, as well as in the possible writing of its conclusion (sources and interpretations)

Marin, Coralie. "Les recueils de correspondances des poilus, vers une mémoire collective française de la Grande Guerre." Thèse, 2009. http://hdl.handle.net/1866/3923.
My research aims to address the phenomenon of the publication of the “poilus” correspondences (French soldiers of the First World War) and to determine their role in the collective memory of the Great War. Preceded by a historiographic review, my work is divided into three chapters around three main themes, correspondences, publishing and memory. The first chapter puts into context the production of letters and identifies the factors influencing it. The second chapter considers the leading goals of publishing correspondences and their transformation over time. Finally, the last chapter analyzes the need for these publications for commemoration of the Great War. Research goes beyond the analysis of letters and focuses on the leading intentions of the editions. The sources used are anthologies of the “poilus” letters, published between 1922 (La dernière lettre) and 2006 (Paroles de Verdun).
