The term 'Retinitis pigmentosa' (RP) represents a group of inherited, late-onset diseases characterised by progressive retinal degeneration due to photoreceptor death. Mutations in the RP2 gene are found in 7-18% of patients with X-linked RP, one of the most severe forms. The RP2 gene product is a membrane-associated protein which encompasses two distinct domains. The N-terminal domain is well characterised as possessing GTPase-activating protein (GAP) activity towards the small GTPase ARL3 and thus regulate the transport of lipid-modified proteins within the photoreceptor cell. However, it is not known if the loss of this particular function of RP2 is the sole reason that causes the disease, while the role of the protein's C-terminus remains unknown. This thesis focuses on the characterisation of two novel protein-protein interactions of RP2 with the aim to investigate novel roles of the protein. Firstly, evidence is provided that a highly-conserved cluster of RP2 residues that span both the N- and C-terminus participate in direct interaction with Osteoclast-stimulating factor 1 (OSTF1). Two hypotheses are explored about the potential role of the complex in SRC-mediated RP2 phosphorylation and the regulation of cell motility. Secondly, the catalytic subunit of DNA-dependent protein kinase (DNA PK) is identified as a novel interaction partner of RP2 in cultured cells. The two proteins are shown to co-localise in the nuclear and membrane compartments of a retinal-derived cell line and might engage in a kinase-substrate relationship. So far, no evidence was found that RP2 participates in the canonical function of DNA PK which is the regulation of DNA double-stranded breaks. Finally, the CRISPR/Cas9 genome editing method was applied on zebrafish embryos to generate a novel vertebrate animal model for the loss of RP2 function. One out of three different zebrafish lines with rp2 mutations was shown by histology to have mild late-onset thinning of the photoreceptor outer segments. The present thesis reports previously unexplored aspects of RP2's function and will, therefore, contribute to understanding the molecular mechanisms that underlie RP. Moreover, this thesis will contribute to the discussion about the usefulness of zebrafish as an RP model.

The serine/arginine-rich (SR-) family proteins constitute a diverse group of pre-mRNA splicing factors that are essential for viability. They can be characterised based on the presence of one or two RRMs and an RS domain. A subset, of which SRSF1 is the prototype, is capable of nucleocytoplasmic shuttling; a process governed by continual cyclic phosphorylation of the RS domain. In contrast, SRSF2, another member of the SR family, is unable to shuttle due to the presence of a nuclear retention sequence (NRS) at the C-terminus of its RS domain. When this NRS is fused to SRSF1, it prevents nucleocytoplasmic shuttling of the SRSF1-NRS fusion protein. In addition to its nuclear roles, SRSF1 is directly associated with the translation machinery and can activate mRNA translation of target transcripts via an mTOR-dependent mechanism. The specific mRNA translational targets that SRSF1 serves to regulate encode numerous factors including RNA processing factors and cell-cycle proteins. The aim of this work is to study the physiological relevance of SRSF1 cytoplasmic functions, as previous data have relied on overexpression systems. CRISPR/Cas9 editing was used to knock-in the NRS naturally present in SRSF2 at the SRSF1 genomic locus, creating an SRSF1-NRS fusion protein. After numerous attempts, it was only possible to obtain a single viable homozygous clone in mouse embryonic stem cells (mESCs), despite being able to successfully tag the genomic SRSF1 locus. This strongly suggests that the ablation of SRSF1 shuttling ability is highly selected against in mESCs. To assess the physiological importance of SRSF1 nucleocytoplasmic shuttling during development, a mouse model for SRSF1-NRS was also developed. SRSF1-NRS homozygous mice are born at correct Mendelian ratios, but are small in size and present with severe hydrocephalus. Finally, proteomics was used to identify interactors of endogenous cytoplasmic SRSF1 and those that bind the NRS of SRSF2 to gain insights into the mechanism of nuclear retention for non-shuttling SR proteins. In summary, this work analyses the physiological relevance of cytoplasmic SRSF1 function and the consequences of the SRSF1-NRS allele in mouse development.

創意媒體研究中，圖像/視頻再藝術作為有表現力的用戶定制外觀的創作手段受到了很大關注。交互設計中，特別是在圖像空間只有單張圖像或視頻輸入的情況下，運用計算機輔助設計虛擬地再渲染關注物體的風格化外觀來實現紋理替換是很強大的。現行的紋理替換往往通過操作圖像空間中像素的間距來處理紋理扭曲，原始圖像中潛在的紋理扭曲總是被破壞，因為現行的方法要麼存在由於手動網格拉伸導致的不恰當扭曲，要麼就由於紋理合成而導致不可避免的紋理開裂。圖像/視頻拼貼畫是被發明用以支持在顯示畫布上並行展示多個物體和活動。隨著數字視頻俘獲裝置的快速發展，相關的議題就是快速檢閱和摘要大量的視覺媒體數據集來找出關注的資料。這會是一項繁瑣的任務來審查長且乏味的監控視頻並快速把握重要信息。以關鍵信息和縮短視頻形式為交流媒介，視頻摘要是增強視覺數據集瀏覽效率和簡易理解的手段。 / 本文首先將圖像/視頻再藝術聚焦在高效紋理替換和風格化上。我們展示了一種交互紋理替換方法，能夠在不知潛在幾何結構和光照環境的情況下保持相似的紋理扭曲。我們運用SIFT 棱角特徵來自然地發現潛在紋理扭曲，並應用梯度深度圖復原和皺褶重要性優化來完成扭曲過程。我們運用GPU-CUDA 的並行性，通過實時雙邊網格和特徵導向的扭曲優化來促成交互紋理替換。我們運用基於塊的實時高精度TV-L¹光流，通過基於關鍵幀的紋理傳遞來完成視頻紋理替換。我們進一步研究了基於GPU 的風格化方法，並運用梯度優化保持原始圖像的精細結構。我們提出了一種能夠自然建模原始圖像精細結構的圖像結構圖，並運用基於梯度的切線生成和切線導向的形態學來構建這個結構圖。我們在GPU-CUDA 上通過並行雙邊網格和結構保持促成最終風格化。實驗中，我們的方法實時連續地展現了高質量的圖像/視頻的抽象再藝術。 / 當前，視頻拼貼畫大多創作靜態的基於關鍵幀的拼貼圖片，該結果只包含動態視頻有限的信息，會很大程度影響視覺數據集的理解。爲了便於瀏覽，我們展示了一種在顯示畫布上有效並行摘要動態活動的動態視頻拼貼畫。我們提出應用活動長方體來重組織及提取事件，執行視頻防抖來生成穩定的活動長方體，實行時空域優化來優化活動長方體在三維拼貼空間的位置。我們通過在GPU 上的事件相似性和移動關係優化來完成高效的動態拼貼畫，允許多視頻輸入。擁有再序核函數CUDA 處理，我們的視頻拼貼畫爲便捷瀏覽長視頻激活了動態摘要，節省大量存儲傳輸空間。實驗和調查表明我們的動態拼貼畫快捷有效，能被廣泛應用于視頻摘要。將來，我們會擴展交互紋理替換來支持更複雜的具大運動和遮蔽場景的一般視頻，避免紋理跳動。我們會採用最新視頻技術靈感使視頻紋理替換更加穩定。我們未來關於視頻拼貼畫的工作包括審查監控業中動態拼貼畫應用，並研究含有大量相機運動和不同種視頻過度的移動相機和一般視頻。 / Image/video restyling as an expressive way for producing usercustomized appearances has received much attention in creative media researches. In interactive design, it would be powerful to re-render the stylized presentation of interested objects virtually using computer-aided design tools for retexturing, especially in the image space with a single image or video as input. The nowaday retexturing methods mostly process texture distortion by inter-pixel distance manipulation in image space, the underlying texture distortion is always destroyed due to limitations like improper distortion caused by human mesh stretching, or unavoidable texture splitting caused by texture synthesis. Image/ video collage techniques are invented to allow parallel presenting of multiple objects and events on the display canvas. With the rapid development of digital video capture devices, the related issues are to quickly review and brief such large amount of visual media datasets to find out interested video materials. It will be a tedious task to investigate long boring surveillance videos and grasp the essential information quickly. By applying key information and shortened video forms as vehicles for communication, video abstraction and summary are the means to enhance the browsing efficiency and easy understanding of visual media datasets. / In this thesis, we first focused our image/video restyling work on efficient retexturing and stylization. We present an interactive retexturing that preserves similar texture distortion without knowing the underlying geometry and lighting environment. We utilized SIFT corner features to naturally discover the underlying texture distortion. The gradient depth recovery and wrinkle stress optimization are applied to accomplish the distortion process. We facilitate the interactive retexturing via real-time bilateral grids and feature-guided distortion optimization using GPU-CUDA parallelism. Video retexturing is achieved through a keyframe-based texture transferring strategy using accurate TV-L¹ optical flow with patch motion tracking techniques in real-time. Further, we work on GPU-based abstract stylization that preserves the fine structure in the original images using gradient optimization. We propose an image structure map to naturally distill the fine structure of the original images. Gradientbased tangent generation and tangent-guided morphology are applied to build the structure map. We facilitate the final stylization via parallel bilateral grids and structure-aware stylizing in real-time on GPU-CUDA. In the experiments, our proposed methods consistently demonstrate high quality performance of image/video abstract restyling in real-time. / Currently, in video abstraction, video collages are mostly produced with static keyfame-based collage pictures, which contain limited information of dynamic videos and in uence understanding of visual media datasets greatly. We present dynamic video collage that effectively summarizes condensed dynamic activities in parallel on the canvas for easy browsing. We propose to utilize activity cuboids to reorganize and extract dynamic objects for further collaging, and video stabilization is performed to generate stabilized activity cuboids. Spatial-temporal optimization is carried out to optimize the positions of activity cuboids in the 3D collage space. We facilitate the efficient dynamic collage via event similarity and moving relationship optimization on GPU allowing multi-video inputs. Our video collage approach with kernel reordering CUDA processing enables dynamic summaries for easy browsing of long videos, while saving huge memory space for storing and transmitting them. The experiments and user study have shown the efficiency and usefulness of our dynamic video collage, which can be widely applied for video briefing and summary applications. In the future, we will further extend the interactive retexturing to more complicated general video applications with large motion and occluded scene avoiding textures icking. We will also work on new approaches to make video retexturing more stable by inspiration from latest video processing techniques. Our future work for video collage includes investigating applications of dynamic collage into the surveillance industry, and working on moving camera and general videos, which may contain large amount of camera motions and different types of video shot transitions. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Li, Ping. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves 109-121). / Electronic reproduction.

Tendo atuado no meio artístico e intelectual brasileiro do segundo pós-guerra até o fim da década seguinte, o veneziano Ruggero Jacobbi (1920-1981) foi um destacado crítico, tradutor e difusor da literatura brasileira, especialmente do drama e da lírica. A pesquisa procura, na perspectiva dos Estudos Descritivos da Tradução, recorrer ao instrumental da crítica genética aplicado à grandiosa tradução Invenzione di Orfeo, trabalho que lhe teria tomado décadas de dedicação, a partir da obra maior do poeta nordestino Jorge de Lima. O levantamento de documentos em acervos na Itália permitiu a consolidação de um dossiê genético a partir do qual se discute o processo tradutório no bojo da atuação brasilianista de Jacobbi. Os nomes do poeta Murilo Mendes e da filóloga Luciana Stegagno Picchio surgem no estudo como frequentes coadjuvantes deste que talvez tenha sido o empreendimento mais ambicioso do amigo. Antes da reconstituição crítico-genética, no entanto, apresenta-se a fulgurante presença da obra lírica do poeta alagoano no distante país peninsular, desde a primeira figuração por obra de Giuseppe Ungaretti até as investidas exegéticas fundamentais de Stegagno Picchio. Para tanto, por sua vez, apresenta-se e se discute a trajetória geral, brasileira e, depois, brasilianista de Ruggero Jacobbi, com atenção ao legado relativo à lírica nacional, que culmina no objeto maior desta dissertação. Entre a teatralização engajada da Litania dos Pobres de Cruz e Sousa para uma montagem brechtiana apresentada no Teatro Brasileiro de Comédia (TBC) em 1950 e a publicação póstuma do grande exemplo de transcriação, guia-nos o espírito crítico marxista-gramsciano e impuro de um intelectual marcado pelo ecletismo e pela contundência inconformista, formado em meio aos herméticos florentinos da era fascista e movido a refratar sua expressão insone em poesia, em teatro, no cinema, no diário, no ensaio, na crítica, na historiografia literária, na antologia e na tradução. / Since the Venetian Ruggero Jacobbi (1920-1981) acted in the Brazilian artistic and intellectual world from the second postwar until the end of the next decade, he was an important literary critic, translator and diffuser of the Brazilian literature, especially of the drama and lyric poetry. This research aims, in the Descriptive Translation Studies perspective, to use tools from the genetic editing (critique génétique) and apply them to the magnificent translation Invenzione di Orfeo, which work supposedly took some decades of dedication, of the most important work of the Brazilian northeastern poet Jorge de Lima. The process of gathering documents in documentary archives in Italy allowed the make of a genetic dossier, with which it was possible to discuss the translation process, in the Brazilianist works of Jacobbi. The names of the poet Murilo Mendes and of the philologist Luciana Stegagno Picchio appeared in this research because they have shared with Jacobbi the experience of carrying out the most ambitious project of his professional life. Before of the critical-genetic reconstitution, however, there was the brightening glow: the reception of the poetic work of the Alagoan poet in the peninsular country, which includes since the first manifestation made by Giuseppe Ungaretti until the fundamental exegetical attempts of Stegagno Picchio. Before this phase, there was the presentation of the Brazilian and Brazilianist trajectory of Ruggero Jacobbi, and then the discussion on this subject, with special attention to his legacy to the national lyric poetry, which culminated on what, is the main object of this work. In the journey from the political dramatization of Litania dos Pobres (from the poem by Cruz e Sousa) into a Brechtian play presented in the Brazilian Comedy Theater (Teatro Brasileiro de Comédia TBC) in 1950, to the posthumous publication of the great example of transcreation, the guide to us is this impure and marxist-gramscian critic spirit of an intellectual marked by the eclecticism and by the nonconformist force, shaped between the hermetic Florentines of the fascist era, a spirit which was moved to reflect his insomniac expression in the poetry, in the drama, in the filmmaking, in the diaries, in the essays, in the literary criticism, in the literary historiography, in the anthology and in the translation.

The authors of these videos are women of different ages and various social classes. They share their opinions on the strategies and beautification products in a very personal way in front of the camera. This all happens in a homemade movie set, usually in their sleeping room. Other places can also be the set, so that all things can be done in an informal atmosphere, more suitable to a direct and friendly conversation with the audience . YouTube is a platform for sharing videos that became popular in a short period. Since the mid 2000s it won thousands of users across the globe. Something comparable to the range of previous forms of communication for the purpose of audiovisual broadcasting and television, except for the fact that now we are talking about a type of interaction in which we are all potentially transmitters and receivers of information. In this work, we will give attention to some aspects of the way these videos are being produced and what seemed, to some extent: be related to an inherited experience of communication on television; happen as a way to update beautification practices of the past (like the so called beauty meetings ); be a way to produce subjectivities through a "self-editing process." The research grows from a sampling of the videos (more qualitative than quantitative) the construction of a logbook and a survey on the literature of the history of YouTube, the language of video, television and today's consumer society / A presente pesquisa baseia-se na análise de vídeos amadores sobre práticas de embelezamento postados na plataforma YouTube. Mulheres de idades e classes sociais variadas são as autoras desses vídeos. Diante da câmera, elas compartilham suas opiniões acerca das estratégias e produtos do embelezamento de forma bastante pessoal. Isso tudo acontece, num set de filmagem caseiro, geralmente no quarto. Outros lugares também podem servir de cenário, contanto que tudo possa ser realizado num clima informal, mais propício a uma conversa direta e amigável com a audiência. O YouTube é uma plataforma de postagem e compartilhamento de vídeos que popularizou-se em pouco tempo. Desde meados dos anos 2000, ele conquistou milhares de usuários pelo globo, algo comparável ao alcance de formas anteriores de comunicação com propósito de difusão audiovisual como a televisão. Só que agora, estamos falando de um tipo de interação em que somos todos potencialmente emissores e receptores de informação. Neste trabalho, daremos atenção a alguns aspectos relacionados ao modo como esses vídeos vem sendo produzidos e que nos pareceu, em alguma medida: ter relação com uma experiência herdada da comunicação pela televisão; acontecer como uma forma de atualização de práticas de embelezamento de antigamente (como os encontros de beleza); ser uma forma de fabricar subjetividades por meio de uma edição de si . A pesquisa se desenvolve a partir de uma amostragem dos vídeos, (mais qualitativa que quantitativa) da construção de um diário de bordo e de uma pesquisa bibliográfica sobre a história do YouTube, da linguagem do vídeo, da televisão e da atual sociedade de consumo

L’édition du génome repose sur la création de cassures double brin à un endroit précis du génome à l’aide de nucléases artificielles (ZFN, TALEN, CRISPR/Cas9) et sur les différents systèmes de réparation que la cellule va mettre en place pour réparer ces dommages. Les deux systèmes de réparation principaux sont le NHEJ (Non Homologous End Joining) et la RH (Recombinaison Homologue). Le NHEJ consiste en une ligation directe des extrémités de la coupure pouvant induire de petites insertions ou délétions avant la ligation. Ces mutations, si elles sont introduites dans un exon, vont modifier le cadre de lecture et pouvoir inactiver le gène cible (Knock Out). La RH permet la réparation de la cassure en recopiant les informations présentes sur la chromatide soeur. Si un ADN exogène comportant des homologies avec la séquence à réparer est inséré avec les nucléases artificielles, la cellule peut le prendre comme matrice de réparation, il est ainsi possible d’insérer n’importe quelle mutation ou transgène de manière précise (Knock In). Ici, différentes stratégies ont été développées pour optimiser ces approches d’édition du génome. Le couplage du domaine Nter de la protéine CtIP à la nucléase Cas9 permet d’augmenter le taux d’insertion par homologie d’un transgène au site de coupure. Le couplage de l’exonucléase Trex2 à la nucléase Cas9 nickase permet quant à lui d’augmenter le taux de mutation après coupure. Ces nouvelles approches peuvent être largement utilisées et permettent de faciliter l’édition du génome. / Genome editing relies on the ability of artificial nucleases (TALEN or CRISPR/Cas9 system) to induce double strand break into a precise and unique sequence in a whole genome and on the different DNA repair system. The two major DNA repair systems are NHEJ (Non Homologous End Joining) and HR (Homologous Recombination). NHEJ consists on DNA end direct ligation. This system can lead to deletion or insertion at the cut site. These mutations, when induced in an exon, can induce reading frame change and gene inactivation (Knock out). HR consists on the use of sister chromatid to copy lost information in order to complete the double strand break. If an exogenous DNA with homologies with the targeted DNA is inserted with artificial nucleases, it can be used as a template and can permit to introduce any transgene at the cut site (Knock In). In this work, different strategies were used to optimize genome editing. By fusing Nter part of CtIP to Cas9, the KI rate of an exogenous DNA is increased and by fusing Trex2 exonuclease to Cas9, the mutation rate induced is also increased. These two approaches can be widely used to improve genome editing strategies.

São muitas as parcerias no cinema, mas a que relaciona o diretor de cena ao diretor de fotografia é certamente a principal. A proposta desta dissertação de mestrado é analisar o estilo de fotografia criado por Eduard Tissé em três dos filmes que trabalhou com Eisenstein. A metodologia teórica da pesquisa baseia-se em Roland Barthes a partir da análise do artefato primeiro do cinema, que é o fotograma. As dimensões sociais ligadas ao materialismo dialético e suas aplicações ao filme, na forma como o espectador promove a leitura de sentidos, preocupavam o diretor soviético. Com isso evidencia-se o princípio conceitual de Eisenstein, desenvolvido pela célula de montagem, na visão da sua missão sócio-cultural em busca da fotografia do conflito. / There are many partnerships in the movie business, but that between director and director of photography is certainly the main one. The purpose of this dissertation is to analyze the style of photography created by Eduard Tissé in three of the movies he worked with Eisenstein. The theoretical research methodology is based on Roland Barthes from the analysis of the first film artifact: the frame. The social dimensions related to the dialectical materialism and its applications to the cinema - the way the audience reads the film sense - worried the soviet director. With that, the conceptual principle developed by Eisenstein is highlighted in search of the conflict cinematography.
