A doxorrubicina (DOX) tem se mostrado eficaz no tratamento de cânceres sólidos e hematológicos, mas a sua potencial cardiotoxicidade irreversível, limita o sucesso do tratamento, levando a um baixo índice terapêutico. O selol, mistura de selenitotriacilglicerídeos, mostrou atividade citostática em ensaios in vitro e demonstrou habilidade em reduzir a viabilidade de células resistentes à DOX. Os objetivos gerais do presente trabalho foram: 1) desenvolver uma nanocápsula contendo selol e doxorrubicina com diâmetro próximo a 200 nm, 2) avaliar sua atividade anticâncer in vitro e in vivo, e 3) verificar o seu potencial cardiotóxico. A formulação obtida consistiu de nanocápsulas com núcleo de selol e com invólucro de poli(metil vinil-éter co-anidrido maléico) conjugado à doxorrubicina. As nanocápsulas apresentaram-se estáveis e monodispersas. Para os testes in vitro, foram utilizadas as células de adenocarcinoma mamário murino (4T1) e células de fibroblasto murino como célula não tumoral (NIH-3T3). Os tratamentos DOX (doxorrubicina), NCS-DOX (nanocápsulas de selol contendo doxorrubicina) e Pol-DOX (produto da reação entre PVM/MA e doxorrubicina) provocaram significativa redução na viabilidade de células 4T1. Ensaios de interiorização mostraram que NCS-DOX e Pol-DOX são mais interiorizadas do que DOX livre em células 4T1. NCS-DOX manteve o potencial da DOX em expor a fosfatidilserina na face externa da membrana em células 4T1, sendo este evento um dos que indica a ocorrência de apoptose. NCS-DOX apresentou maior capacidade de provocar fragmentação de DNA, além de provocar maior alteração na polarização mitocondrial do que DOX. NCS-DOX também foi capaz de gerar maior produção de EROs em tempos de 3 e 24 horas de exposição do que DOX. NCS-DOX e Pol-DOX alteraram a distribuição intracelular da DOX quando comparados com a exposição à DOX livre, do núcleo para a mitocôndria. Em estudos in vivo a NCS-DOX apresentou mesma habilidade da DOX em reduzir o crescimento do tumor de células 4T1, além de apresentar a mesma biodistribuição em camundongos BALB/c. A NCS-DOX não elevou os níveis de CK-MB quando comparado ao controle, o mesmo efeito não foi observado para DOX livre. Portanto, conclui-se que a NCS-DOX é eficaz contra células cancerosas 4T1 in vitro e in vivo, e menos cardiotóxica que a DOX in vivo. ______________________________________________________________________________________________ ABSTRACT
Doxorubicin (DOX) has shown to be effective in the treatment of solid and haematological cancers, but its potential irreversible cardiotoxicity limits the success of the treatment, lowering its therapeutic index. The selol, selenitotriacylglicerides mixture, has shown cytostatic activity in in vitro tests and ability to reduce the viability of doxorubicin-resistant cells. The general goals of this study were: 1) to develop nanocapsules containing selol and doxorubicin with diameter close to 200 nm, 2) to evaluate its in vitro and in vivo anticancer activity, and 3) to check its cardiotoxicity. The formulation consisted of nanocapsules with a core of selol and a shell of poly (methyl vinyl ether-co-maleic anhydride) conjugated to doxorubicin. The nanocapsules were stable and monodisperse. For in vitro tests, murine mammary adenocarcinoma cells (4T1) and fibroblast murine as non-tumor cell (NIH-3T3) were used. The treatments DOX (doxorubicin), NCS-DOX (nanocapsules of selol containing doxorubicin) and Pol-DOX (product of the reaction between PVM/MA and doxorubicin) caused a significant reduction in the viability of 4T1 cells. Internalization assays showed that NCS-DOX and Pol-DOX are more internalized than free DOX by 4T1 cells. NCS-DOX, similarly to free DOX, expose phosphatidylserine on the outside face membrane in 4T1 cells, this is an event that indicate apoptosis. NCS-DOX showed an increased ability to cause DNA fragmentation and to disturb the mitochondrial membrane polarization in comparison to free DOX. NCS-DOX was also able to induce higher production of ROS, at 3 and 24 hours of exposure. NCS-DOX and Pol-DOX altered intracellular distribution of doxorubicin when compared to free DOX alone, from the nuclei to the mitochondria. In in vivo studies, NCS-DOX and free DOX showed the same ability to reduce 4T1 tumor growth, and presented the same biodistribution in BALB/c mice. The NCS-DOX did not increase CK-MB levels when compared to the control. Free DOX significantly increased CK-MB activity. Therefore, it is concluded that the NCS-DOX is effective against 4T1 cancer cells in vitro and in vivo, and less cardiotoxic than free DOX in vivo.

Texto completo da fonteStarting with both an analytic examination of the rite of exorcism in the roman ritual of 1952 and of its ritual action, we make appear their conceptual underpinnings. The conception of possession according to the roman ritual is confronted to possession in non-Christian cults and then traced through its own inheritance due to ancient cultures, the Bible, early Christianity and its subsequent evolution. We then critically interpret today's theological debate throughout its historical development. In the same way, we treat the present practice of exorcism within the occidental catholic church of roman rite (mainly France, Germany, Switzerland, Italy, USA). Lastly, we turn to a hermeneutic analysis of the experience of possession and the pertinence of exorcism in the light of religious anthropology and theology, paying particular attention to the articulation of the epistemological relationship between the psychological and the spiritual as perceived by catholic faith

Texto completo da fontePeer tutoring and deafness are here associated. A first part relates the stages of tutoring before defining and placing its scientific frame for references. This frame requires a psychosocial viewpoint and Moscovici in particular, as well as Piaget's and Vygotski's contribution to cognitif development psychology. These movements bring out genetic development psychology with sociocognitif approach : social interactions are considered with respect to the developmental route of the interacting persons. Then, the handicap of deafness is described with the difficulties it emphasises concerning an educational approach. Therefore our research is based on peer tutoring interaction for deaf tutees. The tutors are deaf, half-deaf or hearing. A quantitative approach shows that deaf tutees progress with peer tutoring. However, a qualitative approach of the interactions doesn't allow us to isolate exactly a data in communication field which would be present in this process of progress. However, the variant "communication" has a positive effect on the tutees' progress. Moreover, the qualitative observation brings out some constant behaviours in peer tutoring relation. For example the construction of an area for communication. Some motivationnal factors would be operating too and would value relational effects

Texto completo da fonteAfter the establishment of Buddhism in India, his influence reached the nations, allowing their political and social currents to be engaged with the various beliefs of Buddhism. Maitreya, absorbing various ideas, such as, millenarianism, paradise, eschatology, revolution and asceticism, became one of the most influential deities, who are very much functional in various domains. The scriptural origin of Maitreya is ambiguous and unclear; meanwhile the developments of Maitreya that appear in various traditions are vibrant and diverse. Thus this thesis will identify the scriptural source of departure of Maitreya myth by focusing on the "anointment" detail of Maitreya. Then we will demonstrate the influence of Maitreya cults in various Asian traditions. To analyze numerous cults, Nattier’s version of Maitreya's typology was modified; the modified version accounts for the major themes of Maitreya myth, which are, interpreter's perspective, mysticism, paradise, Mo-fa and devotionalism. For the last section, this thesis will examine the image of Buddhist triads in relation to Maitreya, in comparison with other Buddhist countries in Asia. The usages and variants of triads in Buddhist nations display how the cults were interpreted, influenced and absorbed in the societies. Going through scriptural, typological and iconographical analysis of Maitreya, this thesis will reveal the process of dissemination of Buddhist ideas through the prisms of shared beliefs, political needs and cultural adaptations of each country

Texto completo da fonteSolid tumor requires a supply of oxygen and nutrients for growth but also for metastasizing to another organ. Tumor angiogenesis is the phenomenon exploited by tumor to fulfill these needs. The"Tip cells" located at the end of sprouting capillaries initiate and guide the growth of neovessels. These cells are currently considered as an important therapeutic target for anti-angiogenic drugs. Many studies have identified a cluster of molecular markers selectively expressed by the \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"Tip cells.\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\" One of these markers called “endocan”, has represented the subject of the thesis work.Endocan is a circulating proteoglycan overexpressed in many human carcinomas, and expression is often associated with poor prognosis. It is suspected to play an important role in tumor development. Through its glycan chain, endocan modulates the effect of growth factors, and also the migration of endothelial cells. My thesis work has focused on the biochemical and functional characterization of mouse endocan in order to obtain a useful animal model for better understanding of the pro tumoral activity of human endocan. The work presented in this manuscript shows that mouse endocan is a chondroitin sulfate proteoglycan but much less glycanated than human endocan. Our data indicate that combinatorial distant domains from the O-glycanation site, located within exons 1 and 2 determine the glycanation pattern of endocan. In SCID mouse model of tumor xenograft we demonstrated that mouse endocan does not exhibit a pro tumoral activity. In opposite to the human homologue, overexpression of mouse endocan in HT-29 cells delayed the tumor appearance and reduced the tumor growth rate. This tumor growth inhibition was mostly supported by non glycanated mouse endocan. Unexpectedly, human non glycanated endocan overexpressed in HT-29, A549, or K1000 cells also delayed the tumor appearance and reduced the tumor growth. Moreover, systemic delivery of human non glycanated endocan also reproduced HT-29 tumor delay. In vitro, endocan polypeptide did not affect HT-29 cell proliferation, nor cell viability.Interestingly, a stromal inflammatory reaction was observed only in tumors overexpressing endocan polypeptide. In addition, depletion of CD122+ cells was able to delete partially the tumor delaying effect of endocan polypeptide. These results reveal a novel pathway for endocan in the control of tumor growth, which involves innate immune cells

Texto completo da fonteDespite their obvious differences, the novels written by Toussaint, Oster and Serena narrate the end of the love story, with a particular emphasis on negativity – which, according to Fabien Gris, constitutes a defining feature of the Minuit novels since the 1980s. These works of fiction focus more on the breakup than on the first time the lovers met. They describe a series of situations that one could classify with this phrase, borrowed from Jean-Philippe Toussaint: “Watching as your love story unravels before your eyes.” The end of the relationship happens right before the eyes of the narrator, and is portrayed according to his perspective, his viewpoint. This dissertation analyzes the separation of the characters according to three visual steps. The first step shows how those novels undo the traditional formula “when their eyes met” (Jean Rousset), and differ from the pattern of the sentimental novel and its topoi. There is no decisive first encounter anymore that determines the destiny of the couple. There is no more face-to-face for the characters, but rather a “face-to-back”, which is the object of the second chapter. The back is studied as both a symbol of the loved one turning around and as a motif situated at the crossing between visual arts and writing. For the spectator, the back symbolizes a final refusal. After she turns around, the loved woman walks away and then disappears. The third step of the argument focuses on the void she leaves behind as she moves on, a blind spot. Left in the position of a spectator, the narrator has to picture her absence. This is the final stage of this visual itinerary: the emptiness before him turns into a projection screen on which pictures of a life are shown, pictures now happening without him. This white page stands in for a void, a vacuity, an abyss – and also a white canvas reflecting the emptiness in the narrator’s life

Texto completo da fonteThis memoir examines the dynamics inherent to the movements in the exercise of power in the Middle Ages, taking as example the case of Frederick Barbarossa, emperor of the Holy Roman Empire from 1152 to 1190. By studying the Gesta Friderici I Imperatoris as the main source of this paper, the goal of this text is to expose the ways in which movements and travels were anchoring parts in the exercise of power. The first part consists in a brief historical overview establishing the situation of the Empire before Barbarossa’s coronation, as well as an exhibition of the evolution of power and institutions linked to its exercise in the Empire. Afterwards, through the writings of Otto of Freising and Rahewin, we see that the sovereign had to travel his lands in order to both be rooted in the tradition of the German itinerant kingship, while also striving towards the new legal concepts of the XIIth century. Thus, Frederick’s reign was at the center of a redefinition of power in the Empire, in direct opposition to the papacy. The studied book, which was actually a tool aiming to spread the imperial ideology of the Hohenstaufen dynasty, gives the reader a better understanding of the needs for the emperor’s journeys in the exercise of his functions, while also representing the monarch as the only holder of the supreme Christian power.

Texto completo da fonteThe object of this thesis is to study the opposition between objectivism and subjectivism in the definition of the mystical spirit in the late 19th and early 20th century, as characterised by the opposition between bergson and levy-bruhl. The apparent opposition between these two conceptions of the human mind - objective, in the case of levy-bruhl, and subjective, in the case of bergson - will be studied. The analysis of the nature of these two apparently contradictory systems will permit an evaluation of their real points of divergence as well as their points of agreement. This will allow the second part of the thesis to explore a central concept of each of these systems - the concept of duration. In the final section, the thesis will consider the rejection of the formal contradiction between objective and subjective duration, that is between collective and individual memory. The analysis of the human mind will be reconsidered beginning from a different concept of time than duration and which is its complete antonym - the instant. If the "birth of the instant" is truly the result of bachelard's critique of bergson, it is possible that the instant also permits a reconciliation of the "objective" and "subjective" social levels, or, to put it another way, of the "rational" and the "mystical" spirits

Texto completo da fonteCette thèse porte sur la production de l’habitation des quartiers informels et sur sa participation dans le processus d’autonomisation des femmes sénégalaises. Elle documente les acteurs, normes et pratiques impliqués dans la construction résidentielle, par l’étude des cas de dix-sept femmes propriétaires et de leur maison dans quatre quartiers de Pikine, en périphérie de Dakar. Supportée par un cadre théorique qui permet de concevoir l’habitation comme un processus dynamique et multidimensionnel, cette étude met en lumière les rapports sociaux développés autour de la mobilisation des ressources pour construire et de la transformation de la forme bâtie. L’approche méthodologique combine des entretiens narratifs avec les propriétaires sur des séquences de vie et l’histoire de leur maison, des relevés architecturaux, des entretiens avec des intervenants locaux et une enquête sur la population et les habitations des quartiers étudiés. Une attention particulière est portée aux moyens individuels et collectifs déployés par les femmes pour la production de leur habitation, afin d’en éclairer les possibilités et contraintes pour la transformation des rapports de genre et l’autonomisation. La thèse montre que les femmes doivent s’appuyer sur divers réseaux pour mobiliser les ressources pour construire, tout en s’assurant de sécuriser celles-ci pour protéger, à long terme, les possibilités qu’elles ont créées pour elle-même et leur famille et, par le fait même, négocier ou transformer les normes sociales qui les désavantagent. Dans ce processus, l’espace résidentiel devient pour les propriétaires un médium des rapports aux autres et peut contribuer au maintien ou à la perte de cet équilibre entre l’accès à de nouvelles ressources et la sécurisation des acquis. Cette étude remet ainsi en question les interprétations, à la base de nombreux écrits et politiques de logement, sur la nature spontanée des quartiers informels et sur les principaux objectifs associés à la construction dans ce contexte. Pour les femmes propriétaires, le processus de production en lui-même représente une voie vers de nouvelles possibilités sociales et économiques porteuses d’une plus grande sécurité et d’une autonomie; pour « construire son futur », transformer activement sa maison est donc souvent plus important que l’obtention d’un bâtiment fini.
This thesis examines informal housing production and its contribution to the empowerment of Senegalese women. It documents the everyday practices, norms and social relationships involved in the construction of houses “from below”, through a detailed analysis of women owners and their houses in four unplanned neighbourhoods of Pikine, in the periphery of Dakar. Considering housing as a dynamic and multidimensional process, this study sheds light on people’s interactions over resource transactions and space, while paying attention to negotiations and inequalities associated with these processes and their consequences for daily life in the city. It describes the strategies through which women owners produce their house and secure a place for themselves and their family in the urban agglomeration, and the spatial and social consequences of these processes. In-depth interviews and life stories with women owners and their families were conducted in combination with architectural surveys of their houses, interviews with key actors involved in land subdivision and housing production, and surveys on land transaction and housing conditions. The thesis shows that women need to draw on a wide range of networks to access resources and at the same time continually negotiate and protect the space of opportunity they have created for themselves; in doing so, they resist and transform social and spatial norms. These results question the usual interpretation according to which obtaining a finished house is the main objective of house construction: for women, the production process itself represents a path towards greater security, but also towards an array of new social and economic possibilities, that are often more significant than the (sometimes never reached) final result.

Texto completo da fonteDuring the last eleven years, Hybrid Organic Inorganic Perovskites (HOIPs) materials have emerged as an exciting topic of research for potential application in solar cell technologies due to their outstanding optoelectronic properties and processing advantages. However, HOIPs materials suffer from several drawbacks with, in peculiar, their lack of stability under operational conditions (light, bias, environment…). To improve this stability is one of the biggest challenges to be addressed before commercialization. The general formula for HOIPs is (A1,A2,A3,A4)Pb(X1,X2)3, where the A sites can be occupied by a distribution of 1 to 4 metallic/organic cations and X sites with halide anions. The role of native vacancy defects has been questioned as a possible cause for HOIPs solar cells degradation. The aim of this work is to understand the defect role in long term stability of HOIPs materials for photovoltaics. For this reason, primary defects were introduced in a controlled way via high energy electron irradiation (1MeV) in sets of layers and solar cells (SCs) fabricated using various HOIPs compounds. Those include the photovoltaic HOIPs prototype, MAPbI3 (A1PbX13), and emergent triple or quadruple cation mixed halide HOIPs, (CsMAFA)Pb(I1-xBrx)3 (A3PbX23) or (GACsMAFA)Pb(I1-yBry)3 (A4PbX23). The HOIPs layers are fabricated according to the same procedure as the HOIPs active SC layers and, subsequently, treated in similar conditions. For A1PbX13 and A3PbX23, the solar cells are of the p-i-n structure with organic hole and electron transport layer (HTL/ETL). The HOIPs layers are deposited on the glass/ITO/HTL (PEDOT:PSS) substrate without or with the top ETL layer (PCBM). For A4PbX23, the solar cells are of the n-i-p type with inorganic ETL (TiO2) and organic HTL (Spiro-OMeTAD) layers. The layers are directly deposited on glass without the ETL layer.Positron Annihilation Spectroscopy (PAS) gives direct evidence for native vacancy-type defects and irradiation induced ones in layers of each HOIP compound. The energy dependence of absorbance shows that natural and after irradiation ageing generates different defect populations in each HOIP compound. These populations strikingly also differ depending on the absence or presence of the top ETL layer for the A1PbX13 and A3PbX23 compounds. The defect populations evolve over ageing duration as long as 3 months. The prominent effects of ageing include (i) band gap modification, (ii) tailing of conduction/valence band extrema and (iii) optical absorption via deep subgap electronic levels. Illumination effects under laser also vary with ageing for each HOIP compound. Asymmetric photoluminescence (PL) peaks in each compound under continuous laser illumination reflect that radiative emission involves Gaussian emission rays with energy, FWHM and height evolving with illumination time. The emission transitions involve shallow localized electronic levels in A3PbX23 and A4PbX23 and resonant ones in A1PbX13. These electronic levels are attributed to specifically illumination-induced defect populations. Natural and after irradiation ageing result in PL decay lifetime spectra resolved into one or two exponential decay components. The decay components number and lifetime are strongly affected by the initial production of irradiation defects and HOIPs composition. Such effects last over 3 months at least in A4PbX23. The p-i-n solar cells exhibit most striking irradiation ageing induced photovoltaics performance. The External Quantum Efficiency (EQE versus photon energy) and the photovoltaic performance (I-V under illumination) of the irradiated solar cells have higher values than those in the reference SCs after 6 to 12 months of ageing. This gives evidence that defect engineering via high energy electron irradiation has a potential for providing innovative processing pathways to enhance the long-term stability of HOIPs photovoltaic performance
