A pesquisa de novas substâncias com atividade anti-Candida é importante devido à ocorrência de resistência por parte de algumas destas espécies aos antifúngicos usuais. Araújo e colaboradores (2009) comprovaram a atividade antifúngica do extrato de Syngonanthus nitens e torna-se relevante a proposta de formulações e o estudo destas. O objetivo geral deste trabalho foi a avaliação da liberação, permeação e retenção na mucosa vaginal in vitro de formulação (creme) contendo o extrato de Syngonanthus nitens, em comparação com outra formulação proposta (gel), para averiguar qual das formulações apresenta mais vantagens para o tratamento da candidíase. Foi validado um método analítico para quantificação do extrato de S. nitens por espectrofotômetro UV-VIS utilizando o padrão luteolina. Os parâmetros analíticos utilizados para avaliar a credibilidade do método analítico foram: seletividade e especificidade, linearidade, limite de quantificação, precisão, exatidão e robustez. O método analítico proposto mostrou-se satisfatório: apresentou seletividade e especificidade; linearidade (os pontos obtidos nas concentrações de 5 a 30 µg/mL apresentaram-se lineares e com um ótimo coeficiente de correlação linear: 0,99996); precisão e exatidão; robustez; e o limite de quantificação foi de 0,5 µg/mL, com coeficiente de variação menor que 5%. Além disso, foram realizados testes de estabilidade preliminar e estudos reológicos, e a formulação creme apresentou resultados adequados para o uso proposto e também apresentou estabilidade. Os ensaios de liberação demonstraram que ambas as formulações apresentam cinética de liberação conforme o modelo de Higuchi, ou seja, a velocidade de liberação do fármaco da matriz do sistema se dá por difusão controlada. Os resultados mostram que as duas formulações apresentam perfil de liberação muito... (Resumo completo, clicar acesso eletrônico abaixo)

For a long time, humankind has lived together with flooding, and lately, those events have grown enormously, in particular, in the urban areas from lots of Brazilian cities. The flooding has been causing uncountable disadvantages to population and to the cities. The present paper aimed to study, through a bibliographic review, the risks and natural disasters caused by those events. Trying to approach their causes and effects under a systemic view it emphasized the landscape point.

Obesity is the most common nutritional problem in dogs and it can cause various harmful effects on animal health. However, the effect of this condition on systolic blood pressure (SBP) in obese dogs is controversial. The indirect method of measuring PAS is the most commonly used in veterinary medicine for the diagnosis of systemic hypertension, because it is more practical and easy to access. There is little scientific information about the comparison of the two non- invasive methods of measurement of blood pressure in obese dogs. Therefore, the objective of this study was to evaluate the SBP in obese dogs by comparing both indirect methods of measuring blood pressure, with oscillometric and doppler vascular in order to verify the differences in blood pressure values, but also the best method to assess the SBP dogs in this body score condition. The study complain blood pressure measurement of 50 dogs, with were divided in obese dogs with mean body condition score (BCS) of 8.42 +/- 0.50 (n = 25) and dogs with ideal BCS of 4.56 +/- 0.51 (n = 25). At comparison of blood pressure values, SBP values obtained by doppler method (152 +/- 16mmHg) were higher than the oscillometric (136 +/- 11mmHg). Correspondence analysis determined by multivariate statistical analysis showed correlation between body condition and the procedure of the SBP. These findings suggest that the indirect method doppler can better reflect the SBP in obese dogs.

The aim of this study is to investigate the spontaneous use of medicinal plants by volunteer patients in the treatment of hypertension and to determine the most used plants in this situation. Data were collected through a questionnaire and a semi-structured guided interview applied to patients from a health center in the Midwest region of the state of Sao Paulo, Brazil. Quantitative analysis identified a high number of hypertensive patients spontaneously using herbal treatment. The referred plants were identified by the Herbarium Botu and researched in the literature as to their therapeutic actions. The biggest mistake was observed in the misuse of the Bilberry for the treatment of hypertension, which reveals that health professionals and the community in general should be more careful. As a result we have published an informative booklet, with emphasis on hypertension concepts and on the use of medicinal plants as an alternative therapy method for this disease in order to provide scientific knowledge and scientific research evidence to this practice.

This research is based on the reflection about the current culture of fruit packages, the standard that states the format and its materials, in the context of a contemporaneous design. It covers space representation issues, material and form representation in addition to the conditioner of the format of the pack as standard load and not the product itself. To analyze the factors related to packaging, we studied the systematic thinking, holistic or ecological and data were arranged in the form of systemic mind maps. The research aims to contribute with information to help in diagnosing the problem in its complexity and interconnected web of factors in order to facilitate better planning of packaging for fruit culture in a future sustainable society.
