Medo e ansiedade são emoções que se originam nas reações de defesa de caráter adaptativo que animais exibem perante ameaças que podem comprometer sua integridade física ou sua própria sobrevivência. Tais situações resultam em um repertório de comportamentos defensivos espécie-específicos, alterações autonômicas e inibição da dor. A dor é descrita por uma variedade de sensações e experiências emocionais associadas e constituída de dois principais componentes: o perceptivo-discriminativo, que permite ao indivíduo reconhecer o estímulo como doloroso e localizá-lo numa região do corpo, e o aversivo-cognitivo-motivacional, que compreende uma série de respostas defensivas, objetivando a autopreservação imediata. O modelo de condicionamento por lugar, para medir efeitos não discriminativos da estimulação nociceptiva, vem sendo utilizado em abordagens recentes para o estudo do componente emocional relacionado à dor. Existem paradigmas baseados na aprendizagem associativa entre o estado afetivo e de dicas ambientais que precedem a aplicação de um estímulo, o qual pode ter propriedade aversiva ou prazerosa, dependendo da resposta que se quer estudar. O presente estudo investigou a ação do fármaco triazolobenzodiazepínico, Alprazolam, sobre o fenômeno da ACL em camundongos, que foram separados em grupos experimentais. No primeiro dia, parte dos animais sofreu estimulação nociceptiva, através da injeção de formalina a 2,5% na pata traseira direita, e foi confinado nos ambientes diferenciados de uma Plataforma Elevada fechada (um lado com grade no assoalho e outro sem grade). No segundo dia, parte dos animais 7 (de acordo com o grupo de estudo) recebeu tratamento farmacológico (Alprazolam ou salina) 30 minutos antes de ser reexposto à plataforma, registrando-se o tempo gasto nos dois ambientes da plataforma elevada fechada...

The Santos Basin is located in the Brazilian continental margin and includes the coast of Santa Catarina, Paraná, São Paulo and Rio de Janeiro states. Its northern limit is the Campos Basin through the High of Cabo Frio and the southern one with the Pelotas Basin through the Platform of Florianópolis, totaling an area of approximately 350,000 square kilometers in a water depth of 3,000 m. The Paranapanema Lineament has WNW / ESE direction, and extends from the area filled by the Paraná Basin, on the border between the states of Sao Paulo and Parana, lasting up to near the ocean floor along with the fracture zone of Rio de Janeiro. The Capricorn Lineament is a feature inherited from the separation between the continents of Africa and South America, and is the main structural feature NW / SE of the Santos Basin center-south region. These two structures together with other ones with continental origin may be associated with structural features in the sediments from the Santos Basin. This work aims to characterize the structures operating in the central portion of the Santos Basin based on subsurface data in the offshore area (2D seismic) together with data from the surface of the continental basement in a way to correlate the Santos Basin structures with the continental regional traits. This data interpolation showed that the structural features of the continent operates on the submerged zone, the seismic sections show these structural trends for the Paranapanema Lineament / Fracture Zone of Rio de Janeiro, Capricorn Lineament and two fault zones that exhibit structures typical of a transfer zone

The area chosen for this study is the island of Trinidade, which is located 1167 km off the Brazilian coast, in parallel Victory at 20 ° 30'S and 29 º 19'W, being the most easterly point of our continent. The isolation of oceanic island of Trinidade leaves no noticeable that she is part of a large submarine volcanic chain oriented east-west lineament known as Vitória- Trindade. Along with the island of Martin Vaz, who is Federal Territory is administered by the Navy of Brazil. Both correspond to Source alkaline volcanic islands. The area of the island of Trinidad has approximately 10 km2. Geologically consisting ankaratritic spills, spills tannbuschiticos, volcanic tuff spills analcite-ankaratrite, phonolite spills, spills nefelinite, pyroclastics, spills grazinite, tinguaitos, olivine-analcitito, calcarenite dunes and wind according to Almeida (1961). The island has its base on the ocean floor, at 5,800 m depth. It is the only place still recognizes preserved volcanic necks and plugs, as well as remnants of a volcano in Brazil. Magmatism occurred here a sodium alkali-silica subsaturated where his wrist was last 50,000 years according to Almeida (1961). It is a place with restricted access due to their distance from the coast, his contribution and hard to be an exclusive area of the Navy. On the island with peaks occur up to 620 meters high, and its rugged mountainous terrain and difficult access to very specific points, as the peak of Desire, peak Fazendinha, Monument and other points on the island. Because of its location far from the coast, its small infrastructure, difficulty of landing and restricted access by sea, the island of Trinidad offers no possibility of tourism, being a military outpost, and scientific basis of great importance, which conduct research in area of marine biology, oceanography, geology and others

The purpose of this literature review is to present the state-of-the-art on the application of tissue engineering techniques in sinus lifts procedures, reporting the influence of these techniques in increasing bone height and volume in the maxillary sinus, and the osseointegration of the implants installed in the grafted areas. PubMed and Scopus databases were searched using the keywords “scaffold” OR “engineered tissue” AND “sinus augmention” OR “sinus floor elevation”. In the initial search 463 articles were selected, of which 19 were selected abstracts reading, with nine papers selected by the end, for evaluation of the application of tissue engineering techniques in sinus lift procedures. Despite the positive results of tissue engineering procedures in sinus floor elevation reported in the selected articles, further studies are still needed, for a better standardization of experimental models and materials used, leading to definitive conclusions about the effects of the application of tissue engineering procedures on bone formation in maxillary sinus lifting procedures.

The aim of this study was to evaluate the clinical, tomographic, and histological similarity within the use of HA+β-TCP (Boneceramic) alone or associated with enamel matrix derived (EMD) proteins in sinus lifting procedures with subsequent dental implant placement. We selected two patients with residual bony ridges between 3 mm and 5 mm in height in need of bone grafts. Six months later, eight implants were installed (two implants at each site). Biopsies were made, and the tissue was processed and stained with HE solution. Tomographic evaluation showed bone height gain up to 10.0 mm on average. Histology showed new bone formation for both groups, with similar bone density and trabecular interconnectivity. It can be concluded that the HA+β-TCP graft isolated or associated to EMD provided bone height gain in sinus lifting procedures, with similar clinical, tomographic and histological characteristics.

Aproximadamente 20 a 22 % das fraturas em felinos são pélvicas e quase metade destas são em ilío, que muitas vezes estão associadas a outras lesões pélvicas ósseas e a tecidos moles. A indicação cirúrgica para o tratamento destas lesões depende do grau de instabilidade, de perda da continuidade óssea, colapso do canal pélvico, fraturas acetabulares, envolvimento de estruturas do eixo de sustentação de peso do animal, lesão nervosa e dor intratável mesmo com uso de analgésicos. O objetivo desta revisão sistemática foi comparar o uso de quatro métodos diferentes para a osteossíntese de ílio em gatos, sendo estes: as placas laterais, placas dorsais, placas em T e, parafusos, fios de Kirschner, fios de aço e polimetilmetacrilato usados em conjunto, em relação às implicações e complicações do uso de cada uma das técnicas. Foram utilizados artigos científicos retrospectivos e prospectivos publicados nas bases de dados informatizados PUBMED, Scielo, Periódico Capes e Google Schoolar que abordassem diferentes técnicas para a osteossíntese de ílio em gatos e foi realizada a análise e comparação de seus dados. Quatro artigos foram selecionados por serem adequados para abordar o tema indicado, todos redigidos em língua inglesa, porém, um sendo de origem francesa e três de origem britânica, cada artigo relatando um tipo diferente de método utilizado. A discussão e a conclusão se deram com base nestes artigos. Nenhuma das técnicas pode ser considerada perfeitamente adequada para qualquer osteossíntese de ílio. Cada uma das quatro possui prós e contras e tem demonstrado melhor eficácia para um tipo específico de fratura ilíaca em gatos, cabendo ao cirurgião veterinário reconhecer e selecionar a melhor a ser utilizada em cada situação

Skull represents the segment with conspicuous adaptations that, in lizards, may be conservative or promoted by selective pressures. The aim of assisting the morphological knowledge of reptiles, we provide a detailed description of the neurocranium of Iguana iguana iguana based on analysis of three dried adult skeletons. The skull of this species has basal characteristics in lizards without closure of cranial openings and general triangular shape. Bony structures that form the caudal base have many fusions, especially on the floor. In the caudal face the exoccipital and the opisthotic are fused and form the otooccipital, which contributes to the formation of the lateral part of the condyle. The central part is formed by the condyle supraocciopital. Fusions and skeletal structures in Iguana are similar to other lizards. There are no autopomorphies in the neurocranium for this species.

Introduction: Upper teeth, especially first premolars and molars, can have a close anatomical relationship with the floor of maxillary sinus. For this reason, accidental displacement of dental roots into the sinus could happen during exodontic procedures. Objective: Description the treatment performed to remove a tooth root within the maxillary sinus, displaced during an extraction procedure. Case Report: Female patient, 39 years of age, which reported being subjected to the extraction of the element 26 for about two months. The patient was reported by the practitioner who performed the extraction that a root was pushed into the maxillary sinus. The treatment plan included surgery to remove the root within the maxillary sinus. Final Comments: Clinicians should be careful during extractions, to prevent these accidents. However, if such complications occur, access to the maxillary sinus is the best treatment option.
