Com o objetivo de propor mecanismos que auxiliem na compreensão da neurobiologia do medo e da ansiedade, diversos modelos animais vem sendo utilizados. Dentre eles destaca-se o Teste de Exposição ao Rato (RET), que é um modelo etológico de interação presa (camundongo) – predador (rato), conhecido por eliciar a expressão de diversos tipos de comportamentos defensivos no camundongo, tais como avaliação de risco, esquiva, congelamento, entre outros. Com o intuito de aumentar a aversividade do modelo proposto por Yang e colaboradores (2004), foi proposto um novo modelo de RET, semelhante ao modelo padrão, porém com alterações de algumas variáveis como aumento da luminosidade, ausência de maravalha, alteração do local de inserção do camundongo no aparato, substituição da tela de arame (usada na separação da superfície) por uma tela de acrílico e arame e uma divisão virtual da superfície em duas partes, uma distante da tela por 10 cm (superfície proximal) e outra com 13 cm até chegar ao túnel (superfície distal). Um estudo piloto realizado comparando o novo teste de exposição ao rato com o modelo padrão demonstrou que no novo modelo de exposição há uma maior preferência pela presa às áreas protegidas (toca e túnel) e uma maior expressão de avaliação de risco, indicando talvez uma maior sensibilidade à expressão de comportamentos defensivos de camundongos e possivelmente a fármacos que atuem no sistema de defesa. No presente estudo foram investigados os efeitos dos (i) benzodiazepínicos diazepam e alprazolam, (ii) dos fármacos ansiogênicos cafeína e pentilenotetrazol e (iii) do antidepressivo fluoxetina (aguda e cronicamente). O tratamento com alprazolam resultou num efeito antiaversivo mais evidente quando comparado ao diazepam. O tratamento agudo 10 com cafeína, por sua vez, apresentou um efeito ansiogênico bastante sutil, diferente... (Resumo completo, clicar acesso eletrônico abaixo)

This work aims to analyze data from a Natural Electric Potential landfill type ditch located in Cordeirópolis (SP). The procedure measures initially involved the assembly and installation of an apparatus cables, sensors and drain geophysical measurements and flow rate of biogas in a ditch later filled by solid waste. Biogas is a product of degradation of organic matter in waste by the action of microorganisms in an anaerobic environment. Its features high methane content in the gas potentially usable as fuel in energy generation systems or steam. The study area is characterized by clayey soil composition change from the diabase sill correlated to the event Serra Geral Formation siltstones overlapping Tatuí with groundwater level site around 50m. The cables were installed vertically in parallel with drain gas manifold, which allowed the collection of data by the technique geophysical logging every 15 days over a period of eight months. For data analysis we used four parameters in the study, the closing time of the ditch, natural electric potential, the flow velocity of biogas and rain. With the tabulated data plots were constructed for each collection day showing values in the range of the cable is in contact with waste (200 cm - 400 cm) and range of the cable in contact with the soil (600 cm - 800 cm). Subsequently graphs were generated with the period of eight months to analyze the data tabulated. A statistical correlation data, which show the influence of rainfall on the production of biogas. The results were satisfactory and demonstrated the feasibility of the research method in studies for the feasibility analysis for the capture of biogas energy

Lower urinary tract disease (LUTD) is a multifactorial disease, wich may be caused by uroliths and calculations, bacterial and viral infections and anatomical abnormalities, among others. The disease can also be of unknown origin in wich case it is called intersticial cystitis. Knowing that the disease may have many causes, it is necessary to know the exact etiology and the best method of diagnosis, to establish specific therapeutic measures for each case. The diagnostic methods most commonly used are: urinalysis, radiography and ultrassonography, but the blood count and biochemistry can be used, trying to assess the overall status of the animal. The terapy used depends on the causative agent of disease, wich may include changes in supply until emergency treatment, azotemia in cats with post-renal. The present study aims to present a complete study of a disease, addressing it’s etiology, diagnosis and treatment, with particular attention to first item

The development of the sugar and alcohol sector and its sugar cane cultivation has been given in an accelerated way in Pontal do Paranapanema, mainly from the last decade, and with this has taken quick changes in the dynamic socio-economic and environmental of the region, further accentuating some conflicts and dilemmas social and environmental legacy. This work was done in order that these issues are further explored, that of moving towards a greater theoretical-scientific maturity, and even has a better apparatus to support measures (corrective or preventive) that show required anti such conflicts. For this purpose, we used the environmental licensing as a means of doing this analysis, since it is one of the main instruments of control/ regulation of the State against the development of activities of the sugar and alcohol sector. We also used a little of the vast potential of information that is contained in the environmental agencies. In this case, we used six Environmental Impact Study / Environmental Impact Report (EIS /EIR), six Preliminary Environmental Reports(PER), five Characterization of Enterprise Memorials (CEM), among other documents /studies present there. Some of the information, organized and made available in this work, has even greater potential to be exploited. It was also made an essential literature survey and of the laws related to licensing and alcohol and sugar sector

The equine locomotors system alterations are very frequent and corresponds a large portion of cases in equine medicine. The most equine veterinarian’s challenge is to do a precise diagnosis of lameness cause to perform a specific and proper treatment as early as possible. The navicular syndrome is considered responsible for one third of lameness causes and, although much studied, its etiology is still not fully understood. The most varied methods of diagnosis, such as x-ray, magnetic resonance, bursography, scintigraphy, computed tomography and ultrasound, have been used to assess podotrochlear apparatus situation in order to diagnose this syndrome. Among them transcuneal ultrasound can be used to observe some important structures such as the flexor surface of distal sesamoid bone, distal deep digital flexor tendon, distal sesamoid ligament entheses odd and the distal phalanx. The aim of this present paper is provide a brief review on the use and the technique of ultrasonography on third phalanx transcuneal region evaluation and its interpretation on navicular syndrome diagnosis in horses
