As concepções dos professores podem determinar as atitudes sociais em relação à inclusão do aluno com deficiência na sala de aula. Dentre dessa temática, pode-se questionar: a concepção de inclusão do professor do ensino regular muda no decorrer do ano letivo após a entrada de alunos com deficiência? Assim, objetivou-se identificar a existência de mudanças de concepções do professor do ensino regular em relação à inclusão. Participaram do estudo cinco professores do ensino regular que atuavam em sala de aula com pelo menos um aluno com deficiência, em três escolas de Município do interior Paulista. Os dados foram coletados durante um ano letivo por meio de três procedimentos: entrevista não-estruturada; segmento bimestral das informações por meio de cadernos de conteúdo e entrevista semi-estruturada, ao final do ano. Os dados foram tratados por meio da técnica designada como análise da enunciação. Dessa análise, foram estabelecidas classes e subclasses, aferidas por juízes para verificar o grau de concordância da análise. Os resultados mostraram mudanças de concepções nas subclasses: expectativa em relação à inclusão do aluno com deficiência no ensino regular, experiência em relação à inclusão, perfil do aluno para ser matriculado no ensino regular; ritmo de aprendizagem do aluno com deficiência na sala de aula regular, avaliação da aprendizagem do aluno com deficiência, dificuldades em lidar com a diversidade, dificuldade em lidar com a disciplina/comportamento do aluno com deficiência e dificuldade para ensinar o aluno com deficiência. Conclui-se que a entrada, por si só, do aluno com deficiência no ensino regular não garantiu a mudança de concepção dos professores.

Some pest management programs employ PCR to identify cry1 genes from Bacillus thuringiensis to predict bacterial toxicity towards different insect pests. However, due to changes on the mode of action of the Cry proteins, new primers had to be designed to detect the new genes. Therefore, an 'in-silico' study of genetic sequences from five cry1 subclasses was carried out and characterized by molecular tools. The design of new primers allows for more precise selection of B. thuringiensis isolates, helping to better direct the programs employing biological control.

Rabies is considered a fatal disease once clinical symptoms have developed. The aim of this study was to evaluate epidemiological aspects and immune response in patients attacked by domestic and wild animals and subjected to post-exposure rabies treatment with equine serum and associated vaccine. Thirty-three patients were evaluated; they were between 13 and 65 years old, 75.8% were male and 24.2% female, and from the Botucatu neighborhood. Twenty healthy control individuals with the same age range were also studied. Specific antibodies to equine immunoglobulins and IFN-γ, IL-2, IL-4, and IL-10 production were evaluated by ELISA. IgM, IgE, IgG and subclasses, and rabies virus antibodies serum levels were determined by nephelometry and seroneutralization methods, respectively. No anaphylactic or serum sickness allergic reactions were observed in patients after treatment. Anti-equine IgG levels were significantly higher than those of IgM after 14 and 28 days of treatment. Protective antibodies to rabies virus > 0.5 UI/ml were detected in 84.6% and 75% of patients at days 14 and 28, respectively. IFN-γ, IL-2 and IL-10 levels in patients before and 48h after treatment were significantly higher than in controls suggesting that both Th1 and Th2 cells were activated in the patients. Serum IgM levels were higher at day 14, and IgG 2 and IgE levels were higher at day 28 of treatment. These results suggest that post-exposure rabies treatment in humans induces significant alterations in patient immune response characterized by increased levels of cytokines, serum levels of specific rabies virus antibodies, and the equine serum components employed in the treatment.

The present study aimed to show the spatial distribution of the Rochas watershed (Avaré-SP, Brazil) soil use capacity using the Idrisi geographical information system in order to contribute to a better territorial organization and the planning of the appropriate soil occupation. The obtained results using this methodology showed that most of the Rocha watershed areas are from the following groups: dystrophic yellow-red latosol (36.64%), eutroferric and distroferric red latosol (30.30%) with sandy texture. There was a predominance of areas with slope classes of 0-12%, plain to wavy relief (61.37% of the watershed area) showing that these areas are appropriate for annual culture plantations with wide use of machinery. Most of these areas were classified as class IV (73.79%) as to use capacity. In the studied area the following subclasses of land use capacity were found: IIe, s; IIIe; IVe; IVs; IVe,s; VIe and VIIe. Capacity subclasses IVe; IVe,s; IVs and Vie were the most significant because they are areas that can be used for agriculture but subject to severe soil impoverishment if there are no special care mainly for annual cultures. The Idrisi geographical information system was efficient to determine soil use capacity of the Rocha's watershed showing that the use of geoprocessing tools makes data analysis easier and faster, allowing digital data storage for future analysis uses mainly for territorial planning and environmental studies.

We define by simple conditions two wide subclasses of the socalled Arnoux-Rauzy systems; the elements of the first one share the property of (measure-theoretic) weak mixing, thus we generalize and improve a counterexample to the conjecture that these systems are codings of rotations; those of the second one have eigenvalues, which was known hitherto only for a very small set of examples.
