Diante disto, o presente trabalho tem como objetivo analisar o comportamento dinâmico e a fadiga termomecânica de fios de LMF Ni-Ti-Cu, submetidos a ensaios dinâmicos em modo de flexão simples (Single Cantilever) utilizando um equipamento de Análise Mecânico Dinâmico (DMA – Dynamic Mechanical Analysis). Assim, foram realizadas análises para determinar a capacidade de amortecimento dos fios, além da fadiga estrutural nos estados martensítico e austenítico. A vida em fadiga dos fios foi avaliada por meio do número de ciclos até a ruptura em função das amplitudes de deformação aplicadas durante o processo de ciclagem mecânica. Os resultados demonstraram uma considerável capacidade de amortecimento dos fios, principalmente durante a transformação de fase e uma influência direta da amplitude de deformação imposta, nos valores de força e no tempo de vida dos fios, revelando que a fadiga situa-se numa faixa entre 103 a 105 ciclos, caracterizando uma fadiga de baixo ciclo. / In most technological applications, Shape Memory Alloy (SMA) actuators are subjected to the most diverse types of mechanical loads, which makes it essential to study the fatigue life of these types of materials. Therefore, the present work has the objective of analyzing the dynamic behavior and thermomechanical fatigue of SMA Ni-Ti-Cu wires, submitted to dynamic tests in single cantilever mode using a Dynamic Mechanical Analysis (DMA). Thus, analyzes were carried out to determine the damping capacity of the wires, besides the structural fatigue in the martensitic and austenitic states. The fatigue life of the wires was evaluated by means of the number of cycles until the rupture as a function of the strain amplitudes applied during the mechanical cycling process. The results demonstrated a considerable damping capacity of the wires, especially during phase transformation and a direct influence of the imposed strain amplitude, on the values of force and the life time of the wires, revealing that the fatigue is in the range of 103 To 105 cycles, characterizing a low cycle fatigue.

Estudos do titânio e suas ligas, como biomateriais, visam melhorar problemas relacionados com a interface osso-implante que podem determinar a qualidade, o tempo de reparação óssea e, por conseguinte o sucesso clínico do implante. O objetivo deste estudo foi avaliar, em ratos, a osteointegração de implantes macroporosos produzidos pelo método da metalurgia do pó (MP), com adição controlada de gelatina. Foram utilizadas, como grupo controle, amostras de titânio comercialmente puro (Ticp) e amostras da liga Ti-13Nb-13Zr obtida pelo processo de MP, sinterizadas a 1150°C / 14 horas (10-5 mBar). Para a obtenção das amostras porosas, foi adicionado até 15% em peso de gelatina aos pós metálicos (Ti, Nb e Zr), as amostras foram tratadas termicamente em forno a vácuo (10-2 mBar) a 300°C / 90 min e sinterizadas. Foi feita a caracterização física dos pós metálicos, da liga sinterizada e amostras porosas. A caracterização biológica iniciou-se pelo teste in vitro de citotoxicidade, de acordo com a norma ISO- 10993-5 (1993), que permitiu a utilização dos implantes em teste in vivo. A avaliação da osteointegração foi realizada em ratos Wistar, macho, em um período de 28 dias. As análises morfológicas, microscopia óptica e microscopia eletrônica de varredura (MEV), avaliaram qualitativamente a osteointegração. Como conclusão, a metodologia inédita do processo de MP modificado pela adição de gelatina, propiciou com êxito a obtenção de implantes metálicos porosos. A gelatina por ser um colágeno, não interferiu na característica final de não-citotoxicidade dos implantes. O tamanho dos poros obtidos por esta técnica permitiu a nutrição e manutenção necessária para a sobrevivência das células, comprovando que os poros e canais formaram uma rede de alta interconectividade comprovando assim o aspecto de osteointegração e osteocondução da liga porosa. / Studies of titanium and its alloys commonly used as biomaterials, aim to improve bone-implant interface related problems which may determine the quality, the bone repairing time and therefore the clinical success of the implant. The goal of this study was to evaluate, in rats, osteointegration of macroporous implants produced by powder metallurgy (PM) method, with controlled addition of gelatin. Were used as control group, samples of commercially pure titanium (cpTi) and samples of the Ti-13Nb-13Zr alloy obtained by the PM process, sintered at 1150ºC / 14 hours (10-5 mBar). To obtaining the porous samples, at most 15% in weight of gelatin was added to metallic powders (Ti, Nb and Zr), the samples were thermally treated in vacuum oven (10-2 mBar) at 300°C / 90 min, and sintered. Physical characterization of metallic powders, sintered alloy and porous samples were made. The biological characterization began by in vitro cytotoxicity essay according with norm ISO-10993-5 (1993), which allowed uses the implants for in vivo testing. The osteointegration evaluation was performed in Wistar rats, males, for 28 days period. The morphological analyses, optical microscopy and scanning electron microscopy (SEM), evaluated qualitatively the osteointegration. Concluding, the unpublished new methodology of PM process modified by addition of gelatin, propitiate with success the obtaining of porous metallic implants. The gelatin as a collagen did not interfered in the final non-cytotoxic implant characteristic. Porous size obtained by this technique allowed the nourishing and necessary maintenance to cell survival, proving that the pores and channels formed a high interconnectable network showing thus the osteointegration and osteoconduction feature of the porous alloy.

Lipopolissacarídeos (LPS) de L. interrogans, S. enterica e B. pertussis foram extraídos e as subfrações monofosforil lipídeo A (MPLA) preparadas por hidrólise. O LPS é responsável por forte resposta imunológica e endotóxica em mamíferos, enquanto o MPLA apresenta baixa endotoxicidade e boa capacidade imunomoduladora. Estudamos a atividade adjuvante de LPS e de MPLA em formulações com antígenos LigA ou OmpA contra leptospirose. Testes de imunização e desafio em hamsters confirmaram alta atividade imunoprotetora de LigA e capacidade adjuvante do MPLA de salmonela e de LPS de leptospiras, mas as formulações não foram capazes de bloquear a colonização renal na leptospirose. Os resultados sugerem diferenças na imunidade protetora sistêmica da imunidade protetora renal. / Lipopolysaccharides (LPS) of L. interrogans, S. enterica and B. pertussis were extracted and the subfraction monophosphoril lipid A (MPLA) prepared by hydrolysis. The LPS is responsible for immunological response and endotoxicity in mammallians, while MPLA has reduced endotoxic activity, but maintain the immunomodulatory capacity. We studied the adjuvant capacity of LPS and MPLA in formulations with LigA or OmpA antigens against leptospirosis. Tests of immunization and challenge in hamsters confirmed the high immune protection activity of LigA and adjuvant capacity of MPLA of salmonela and LPS of lepstopiras, however formulations did not block the renal colonization. The results suggest that there are differences in the systemic immune protection from the kidney immune protection.

Les mucilages pélagiques marins (MPM) sont des phénomènes mondiaux sporadiques et, dans certaines régions, chroniques dans les zones côtières. Ces agrégats gélatineux, enrichis en matière organique et en microorganismes, forment des écosystèmes marins autonomes transitoires allant de 0,5 cm à plusieurs kilomètres de long. Ils correspondent à des étapes évolutives de la neige marine non-sédimentée maintenue dans la zone photique. Durant les dernières décennies une intensification des apparitions des MPM ont été recensées. Ainsi, les MPM sont devenus un sujet de préoccupation pour les populations qui exploitent les ressources côtières et dans le contexte du fonctionnement global de l'écosystème. Malgré l’intérêt scientifique grandissant au cours des dernières décennies au sujet de ces phénomènes, notamment en mer Adriatique, les causes de formation, la dynamique et le rôle respectif des microorganismes dans de tels systèmes restent énigmatiques. La plupart des études réalisées sur les MPM étaient axées uniquement sur les communautés microbiennes eucaryotes par l’utilisation de techniques microscopiques. Or de nos jours, les méthodes moléculaires permettent de se concentrer également sur l'ensemble de la communauté, y compris les procaryotes. Afin d'approfondir notre compréhension de ces phénomènes nous avons étudié un type MPM qui est apparu de manière récurrente et abondante au cours de la dernière décennie dans le sud du Golfe de Gascogne (France), le «Liga». Dans un premier temps, nous avons étudié la formation de ce MPM au travers d’une année complète en suivant la dynamique des communautés archées, bactériennes et eucaryotes par la technique de T-RFLP, technique d’empreinte moléculaire ciblant la petite sous-unité du gène codant pour ARNr. Cette approche a révélé que les communautés microbiennes du Liga étaient différentes des communautés microbiennes marines pour les trois domaines du vivant, et que ces deux communautés étaient gouvernées par des paramètres environnementaux dont la variation était saisonnière. Les archées n’ayant pas pu être détectés dans le Liga, nous nous sommes focalisés sur la structure des communautés bactériennes et eucaryotes au moyen de technologies de séquençage à haut débit. Cette méthode a révélé que le Liga était principalement composé d'espèces marines, même si ces communautés étaient significativement différentes des espèces marines. Dans le Liga, les communautés eucaryotes étaient principalement composées de dinoflagellés, de zooplancton et de cnidaires. Les communautés bactériennes étaient principalement composées d’Alphaproteobacteria et de Gammaproteobacteria. La diversité fonctionnelle du Liga fraîchement formé a été également étudiée pendant les saisons d'apparition de ce phénomène, au printemps et à l'automne. Nous avons ainsi mis en évidence que les communautés microbiennes du Liga avaient potentiellement moins de capacités de résistance au stress et que ces communautés étaient potentiellement plus virulentes que les communautés microbiennes marines. / Marine pelagic mucilage (MPM) is worldwide phenomena occurring sporadically and, in certain regions, episodically in coastal areas. These gelatinous aggregates, enriched in organic matter and microorganisms, form autonomous transitory marine ecosystems ranging from 0.5 cm to several kilometers. They correspond to evolving stages originating from the non-settling early marine snow maintained in the photic zone. During the last decades intensification of MPM events have been noticed. They became a matter of concern both for populations exploiting coastal resources and in the context of global ecosystem functioning. Although increased scientific attention has been paid during last decades to these phenomena in specific areas such the Adriatic Sea, the causes of appearance, the dynamics, and the respective role of microorganisms in such systems remain enigmatic. Most of the studies performed on MPM focused on eukaryotic microbial communities using microscopic techniques. However molecular methods allow nowadays focusing also on the whole community including the prokaryotic part. In order to deeper our understanding of these phenomena we studied a MPM that occurred recurrently and more frequently during the last decade in the south of the Bay of Biscay (France), the “Liga”. In a first step we investigated the formation of this MPM through a complete year by following the dynamics of archaeal, bacterial and eukaryotic communities using T-RFLP fingerprinting targeting the small subunit of rRNA genes. This approach revealed that Liga’s microbial communities where different from marine microbial communities for the three domains of life and that both marine mucilage and marine communities were linked with seasonal patterns. As archaea were not found in the Liga, we focused on bacterial and eukaryotic communities’ structures through high throughput sequencing. The molecular composition revealed that the Liga was mainly composed of marine species although these communities were significantly different from marine species. In the Liga, eukaryotic communities were mainly composed of dinoflagellates, zooplankton and cnidarians species and bacterial communities were mainly composed of Alphaproteobacteria and Gammaproteobacteria. Functional diversity of freshly-formed Liga was targeted during its seasons of apparition, in spring and in autumn. We highlighted that Liga’s microbial communities had less potential capabilities to resist to stress conditions and that these communities were potentially more virulent than marine microbial communities.
