Spontaneous Basal Cell Carcinoma of the Submandibular Gland in a Rat
At necropsy, a white nodule (about 5 Ă 3 mm in size) was observed in the right
submandibular gland of a 10-week-old female GALAS rat. Histopathologically, oval
to spindle-shaped and pale basophilic tumor cells proliferated closely, and
formed variably sized foci. The nodule partially spread into or invaded the
surrounding normal tissue, and necrotic foci were recognized in the tumor.
Immunohistochemically, the nuclei of the tumor cells showed a diffusely positive
reaction for p63, and the cytoplasm showed a diffusely positive reaction for
cytokeratin and negative reaction for αSMA, vimentin, desmin and S-100. Many
tumor cells were positive for PCNA. Ultrastructurally, the tumor cells contained
many tonofilaments in the cytoplasm and a few desmosomes at the intercellular
portion. Based on these findings, the tumor was diagnosed as a basal cell
carcinoma originating from the duct in the rat submandibular gland
Decolonialities in devir, pedagogical praxis and Freirean literacies: studies by a teacher-formator and his agencies
Este estudo investiga processos de decolonialidades em um curso de formação de professoras2: a desconstrução de mitos e crenças sobre o que aparenta ser, na mente e corpos de professoras em formação, os processos de ensino e aprendizagem de lĂnguas e linguagens como prĂĄticas sociais, e como letramentos freireanos podem participar de praxis pedagĂłgicas mediatizadas por meio de materiais pedagĂłgicos criados por este professor-formador. Elaborados com o objetivo de provocar reflexĂ”es decolonizadoras de naturezas mĂșltiplas e heterogĂȘneas, convido as minhas leitoras a viajar por rizomas-suplementos, que se transformam em praxis pedagĂłgicas, que sĂŁo co-construĂdas ao longo dessa pesquisa-em-movimento, sempre em resposta aos questionamentos realizados por professoras em formação, professoras em devir, discentes da disciplina EstĂĄgio Supervisionado. A possibilidade de observar o mundo e a sala de aula a partir da desconstrução de corpos e mentes colonizados, e imaginar as nossas salas de aula a partir de outras perspectivas, Ă© o que faz desta tese, ela mesma, um processo de decolonialidade de corpos e mentes, da qual tambĂ©m participa o corpo e a mente deste pesquisador-colonizado/colonizador, em processos de decolonialidade, em devir. Assim, a leitora Ă© convidada a espiar pelas lentes embaçadas deste pesquisador-etnĂłgrafo nĂŽmade, algumas de minhas praxis pedagĂłgicas, de meus movimentos agĂȘnticos dentro e fora das salas de aulas, e os olhares desconstruĂdos e co-construĂdos, em contĂnua reconstrução em busca de conhecimentos sempre inacabados.This study investigates processes of decolonialities in a formative Teacher Certification Course: the deconstruction of myths and beliefs about what appears to be, in the minds and bodies of teachers in formation, the processes of teaching and learning languages as social practices, and how Freirean literacies can participate in mediatized pedagogical praxis through pedagogical materials created by this teacher-formator. Elaborated with the objective of provoking decolonizing reflections in its multiple and heterogeneous natures, the pedagogical praxis presented in this thesis are rhizome-supplements, in response to the ever-present questions made by teachers in formation, teachers in devir, students of the discipline Supervised Internship. The possibility of observing the world and the classroom environment based on the deconstruction of colonized bodies and minds, and imagining our classrooms from other perspectives, is what makes this thesis itself a process of decoloniality of bodies and minds, in which the body and mind of this colonized/colonizer-researcher, in processes of decoloniality in devir, also participates. Thus, the reader is invited to peek through the blurred lenses of this nomadic researcher-ethnographer, and learn about some of my pedagogical praxis, my movements inside and outside the classrooms, and the deconstructed and co-constructed perspectives in continuous reconstruction in search of the ever-be unfinished knowledge
From the digital interactive whiteboard to the collective web-based curricula: agencies, literacies and translingual practices in an English language program
Este estudo investiga os processos de co-construçÔes webcurriculares em um curso de LĂngua Inglesa, caracterizado pela ausĂȘncia de livro didĂĄtico e cujas construçÔes das aulas sĂŁo mediatizadas pelas tecnologias digitais da informação e comunicação, suas ferramentas e seus recursos. Amalgamados em movimentos agĂȘnticos de alunos e professor, os processos de construção de discursos e enunciados (BAKHTIN, 1929), sentidos e significados (BRUNER, 1960) por meio de prĂĄticas translĂngues (CANAGARAJAH, 2013) oferecem alguns dos elementos mediatizadores para que esses processos de co-construçÔes de novas arquiteturas pedagĂłgicas ocorram. Essa composição caleidoscĂłpica que fomenta a ecologia social e cultural desta pesquisa etnogrĂĄfica Ă© caracterizada por ser interpretativa em busca de significados (GEERTZ, 1973), e nĂŁo uma anĂĄlise de uma ciĂȘncia experimental em busca de uma lei. Assim, este trabalho encontra-se organizado em trĂȘs capĂtulos que discorrem sobre as concepçÔes que envolvem esta pesquisa etnogrĂĄfica e seus processos de construção de dados contemplando os webcurrĂculos, as agĂȘncias e as prĂĄticas translĂngues por meio dos letramentos. A partir dos conceitos de temporalidade (EMIRBAYER e MISCHE, 1998) e da abordagem ecolĂłgica da agĂȘncia (BIESTA e TEDDER, 2007) Ă© possĂvel observar como os movimentos agĂȘnticos de cada um dos sujeitos da pesquisa dialogam em busca de um equilĂbrio outro, a partir de forças que emanam dessa ecologia social, cultural e material. Assim, o leitor Ă© convidado a espiar atravĂ©s das lentes deste pesquisador-etnĂłgrafo, alguns movimentos e olhares construĂdos, cujos elementos mediadores sĂŁo os letramentos com as suas mĂșltiplas linguagens e as tecnologias digitais da informação e comunicação. Tal composição ecolĂłgica propicia a abertura de novas janelas acompanhadas por visĂ”es de mundo outras, cujos elementos possibilitam infinitas combinaçÔes que fomentam a construção de outros tipos de conhecimentos inacabados.English language program, characterized by the absence of textbooks and whose classroom constructions are mediated by digital information and communication technologies, their tools and their resources. The processes of constructing discourses and speeches (BAKHTIN, 1929), sense and meanings (BRUNER, 1960) by means of translingual practices (CANAGARAJAH, 2013) offer some of the mediatizing elements for these processes of co-constructions of new pedagocial architectures to occur. This kaleidoscopic composition that fosters the social and cultural ecology of this ethnographic research is characterized by being interpretative in search of meanings (GEERTZ, 1973), and not an analysis of an experimental science in search of a law. Thus, this work is organized in three chapters that discuss the conceptions that involve this ethnographic research and its processes of data construction contemplating the web-based curricula, the agencies and the translingual practices and the literacies. Based on the concepts of temporality (EMIRBAYER and MISCHE, 1998) and the ecological approach of agencies (BIESTA and TEDDER, 2007), it is possible to observe how the agentic movements of each of the research subjects intertwine in seach of some equilibrium of the other, whose forces emanate from this social, cultural and material ecology. Thus, the reader is invited to peer through the lenses of this ethnographer-researcher, some of the constructed movements and looks, whose mediating elements are the literacies and their multiple languages and the digital technologies of information and communication. Such ecological composition allows the opening of new windows accompanied by other world views, whose elements allow infinite combinations that foment the construction of other types of knowledge, unfinished knowledge

Surgical reconstruction for sphenoâorbital meningioma extending into the sphenoid sinus with hyperostosis
Key Clinical Message Sphenoâorbital meningiomas (SOMs) are complex tumors that grow and extend into nearby structures. SOM tumor growth is often associated with hyperostosis caused by tumor cell infiltration and bone alteration. We describe the case of a 64âyearâold man with SOM that extended into the sphenoid sinus without a direct connection between the intracranial and extracranial lesions. This report emphasizes the importance of identifying the growth patterns of SOMs and assessing the paranasal sinuses adjacent to the hyperostotic orbit walls from preoperative images
