O objetivo do presente estudo foi verificar o efeito da adição de um prebiótico nas características de crescimento, resistência às condições do trato gastrintestinal e remoção de colesterol in vitro, das cepas de Enterococcus faecium CRL183 e Lactobacillus helveticus 416. A fonte de prebiótico foi composta por Inulina GR – Orafti, sendo testadas as seguintes concentrações: 1,0%, 2,0%, 3,0%; 4,0%; 5,0% e 6,0% p/v). Para a avaliação da resistência às condições do trato gastrintestinal, os microrganismos foram colocados em contato com um fluido gástrico simulado por 2 horas (9g/L de NaCl, 3g/L de pepsina, pH 1,8) e com um fluido intestinal simulado por 3 horas (0,9g/L de pancreatina, 12,5g/L de bicarbonato de sódio e 6,0 g/L de Oxgall). Após o período de contato com os fluidos, foram realizadas diluições seriais e plaqueamento em meios específicos. No estudo de redução de colesterol, meios de cultura contendo inulina e colesterol (1%) foram inoculados com as cepas probióticas e incubados em anaerobiose a 37°C/24h. A capacidade de redução do colesterol foi determinada pela diferença entre a concentração de colesterol adicionada ao meio de cultura e a de colesterol residual. Os resultados foram submetidos à análise de variância e teste de médias de Tukey (p≤0,05). A adição de inulina não resultou em alteração no ciclo logarítmico de crescimento dos microrganismos. Porém, quando os dados foram submetidos à análise estatística, constatou-se que a adição de 1% a 4% de inulina inibiu o crescimento de Lactobacillus helveticus 416, sendo que para as concentrações de 5% a 6% estas alterações não foram perceptíveis. A cepa de Enterococcus faecium CRL 183 apresentou crescimento superior na presença de 2% e 4% de inulina. Após o contato com o fluido gástrico simulado, observou-se redução de 1 ciclo logarítmico no crescimento da cepa... (Resumo completo, clicar acesso eletrônico abaixo)

This work aimed to develop a biological system for removal of ammonia nitrogen operating at low concentrations of dissolved oxygen. Thus, a biological upflow vertical reactor was built, in which the affluent pass through the support media until the top. Sludge from an anaerobic stabilization pond of a slaughterhouse unit in the city of Presidente Prudente - SP was used as inoculum. Initially the system operated in batch and afterwards in a continuous flow with different HRT. For feeding the reactor, an initial phases was adopted a synthetic culture media, described by Martins (2007), in order to establish the ideal conditions for the development of Anammox bacteria and subsequently, submitted to the system a slugde effluent of slaughterhouse. The results showed significant removal efficiency of N-NH4+, especially in the phase without recirculation of culture media, with an average of 71% removal, with the proportion of removal of N-NH4 +:N-NO2- average 1: 1,69. For the period of operation with effluent from the slaughterhouse, were not obtained satisfactory results, without confirmation of the proliferation of Anammox bacteria in the system, due to the high presences of organic matter in the same confirmed by high concentrations of COD

This paper tries, across research, books, magazines and charts that relate to the architecture of today, establishing a direction as to the technological advances that may be involved in the architecture project. Such that the configuration space has flexibility to meet the basic architectural principles and the wishes of the user, who should participate as a key character of the decisions of spatialization - interface. Both the personal point of view of their social relations within the housing, and the functional environments equipped and qualified to meet expectations during its use. Respecting the power of free choice of human beings, not to put yourself to the detriment by excessive use of technology. And still look for ways to integrate the individual to society connected to your network - home. Keywords: interface, information, technology, space flexibility

Este trabalho discute sobre como a habitação social vem sendo desenvolvida no Brasil e apresenta uma proposta de loteamento urbano para as classes sociais menos favorecidas economicamente na cidade de Presidente Prudente. A idéia do projeto é a de comparar um loteamento com vias ortogonais, lotes privados e espaços de lazer públicos bem separados, com uma proposta cujas unidades habitacionais estariam dispostas de forma a criar áreas verdes integradas ao convívio social. Para isso foram considerados aspectos sociais, econômicos, formais e funcionais. A elaboração do trabalho começou com estudos sobre o tema e com levantamento bibliográfico, quando nasce essa inquietação sobre habitação social no Brasil, verificou-se a carência de bons projetos arquitetônicos em uma relação quantitativa. A partir daí, foram analisadas diversas pesquisas e propostas que relacionam a urbanização brasileira e a forma como ela se apresenta com relação a unidades habitacionais, com interesse social, ou seja, para pessoas de baixa renda, com foco na cidade de Presidente Prudente (São Paulo). De acordo com esses estudos, foi feito um levantamento de possíveis áreas de implantação de um loteamento onde foi constatada a existência de um terreno não edificado, em uma área com infra-estrutura e dentro do perímetro urbano. Esta área de aproximadamente 100 mil metros quadrados foi escolhida para a realização do trabalho de comparação das diferentes formas de produção do espaço urbano

As cidades brasileiras, ano a ano, vivem um crescente processo de urbanização, o qual nem sempre ocorre de uma maneira ordenada. Tal evento causou e tem causado um déficit de habitação para uma parte da população classificada como baixa renda e que se vê sem opções dignas de moradia. Portanto, este trabalho tem o objetivo de propor um projeto de Habitação de Interesse Social para essa classe mais pobre em uma área já consolidada do município. Trata-se da remoção de um cortiço com habitações insalubres, mas que está contida numa malha urbana central, com equipamentos públicos, servida de infra-estrutura e acesso a transporte público, ou seja, em uma área classificada como de inclusão social na cidade de Presidente Prudente – SP

The pyogenic granuloma, a lesion considered hyperplastic regenerative inflammatory reaction is a finding commonly found in the oral cavity, affecting large numbers of individuals, being more prevalent in females. But its pathogenesis is not well defined and may be associated with numerous factors that stimulate tissue proliferation. Correct diagnosis and treatment plan are essential for success in approach, restoring function and aesthetics to the periodontal tissues. In agreement with the literature, the most common treatment and greater predictability is surgical removal, which involves resection of the lesion, together with its base inserted into the underlying tissue, periosteum and bone tissue. However, the excision can promote aesthetic defects, particularly in anterior regions where it is most affected. This article reports on the importance of a correct surgical approach for removal of pyogenic granuloma in the region of the interdental papilla between teeth 42 and 43, resulting in a good anatomical result and aesthetic.

Studies have reported that alcohol may lead to imbalance in bone formation and resorption, however, its effects on osseointegration of titanium implants continues to be an inconclusive subject. In this context, the aim of this study was to make a biomechanical evaluation of the effect of abusive alcohol consumption on the removal torque of osseointegrated titanium implants. Male Wistar rats (n=30) were divided into two experimental groups (15 each) receiving only water (Control) or 36% alcohol solution oral administration. Thirty days later, all animals were submitted to titanium implant (2.2 mm x 4 mm) placement in the right and left tibiae. The surgical alveoli were prepared with a 2 mm drill mounted in a counter-angle hand-piece (20:1 ratio, 35 Ncm torque at 1200 rpm) under abundant cooling. Five animals from each group were euthanized at 15, 30, and 60 days. Tibiae were submitted to reverse torque analysis. Data obtained were submitted to statistical analysis by the non-parametric Kruskal-Wallis and Dunn Tests (p < 0.05). Animals in the alcohol group presented lower removal torque values when compared with control group animals for all periods tested (p < 0.05). It can be concluded that abusive alcohol consumption can reduce the removal torque of titanium implants placed in rat tibiae, suggesting that alcohol may interfere in the osseointegration process of titanium implants.
