The use of plants to treat diseases or even to cure them is a high diffused popular tradition, and several studies discuss the therapeutic and pharmacological properties of garlic in the reduction of hyperlipidaemias. The objective of the present study was to investigate the influence of the aqueous extract of garlic (Allium sativum) to treat the serum cholesterol of rabbits with experimental hypercholesterolemia. The animals were divided into G1 (control group) and G2 (group treated with garlic). The experiment was developed according to 3 phases: during the 1st phase, all animals were provided with a regular diet to evaluate the basal cholesterol; during the 2nd phase, all animals received a supplemented diet until the end of the experiment, in order to develop hypercholesterolemia and, in the 3rd phase, the animals on G2 received the garlic treatment. The cholesterol registered on the 1st phase was 39.94 ± 9.57 mg dL-1. On the 2nd phase, there was an increase on the serum cholesterol level in both groups - higher than 100 mg dL-1. Concerning the treatment, the garlic did not reduce the serum cholesterol in rabbits.

The interview has been a widely used procedure of research in humanities. Despite the frequent use, researches are not always supported in the literature on research methodology. The aim of this study was to analyze how the interview was used in dissertations and theses in a graduate Program in Education at a university in Sao Paulo state. This study examined 167 final papers developed in to period of five years. Variables focused were: justification for the use of interview, type of interview used, guide elaboration and adaptation, kind of analysis, among others. The results showed that it is still necessary to incorporate the contents of the research methodology underlying the use of the interview to achieve the scientific rigor for this procedure.

The Assistive Technology makes the lives of people without disabilities more practical, but for people with disabilities it can make things possible. For these individuals can provide the conditions, making their limitations are not obstacles to their social and personal empowerment, and may contribute to their effective participation in tasks that were previously impossible, such as remaining seated correctly. A segment on which the necessary assistive technology works, is the adaptation of furniture such as chairs, tables, chairs-to-wheels for individuals with disabilities, as well as cerebral palsy. The study aimed to conduct a survey and brief description of theses and dissertations produced in Brazil on furniture adapted for students with cerebral palsy. We made searching in databases of libraries of major universities and federal state national banks, theses and dissertations. Nine studies were selected for description. It was concluded that there is a considerable array of professionals, both in engineering as the field of rehabilitation, to contribute in the adaptation, creation and even the manufacture of furniture for children with cerebral palsy and that the securities most studied are the chairs and their components.

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)
