Biosusceptometria de corrente alternada para avaliação do trânsito gastrintestinal de alimentos líquidos em ratos

The gastrointestinal tract is the main route of nutrients absorption and drugs delivery. Is important to know the parameters related to the tract, like gastric emptying and gastrointestinal transit, in order to better understand the behavior of different kind of meals or drugs passing through the GIT. Many techniques are used to study these parameters, such as manometry, scintigraphy, phenol red, activated charcoal and carbon-13 reading. However, these methods use radiation, are invasive and require animal sacrifice. As an alternative proposal, the Alternate Current Biosusceptometry (ACB), a magnetic technique, has proved to be effective for these studies with small animals, in a noninvasive way, low cost, radiation free and avoiding the animal death. Associating the ACB to magnetic micro or nanoparticles used as tracers, it is possible to observe the meal behavior inside of the GIT. Focusing meanly on liquid meals digestion, this paper had the objective to evaluate the efficiency of the ACB technique in gastric emptying and gastrointestinal transit evaluation of liquid meals in rats. To perform the experiments, magnetic nanoparticles (ferrite, MgFe2O4) were used on a 1,5 ml solution introduced by gavage on similar weight and age rats. The sensor made by 2 pairs of coils, capable of generating and detecting magnetic fields, creates a field on the interest place and when this field is in contact with the marked meal, it changes, resulting on a variation of the measured voltage. The voltage variation is analyzed and is obtained a particle concentration on the interest region. The results showed that is possible to apply the ACB technique on the GIT evaluation of liquid particles digestion, gastric emptying and meal cecum arrival time curves were obtained and from that, is possible to observe a pattern of gastrointestinal transit. Both mean process time values were acquired, proving the technique capability of ...

A influência da Shantala para o desenvolvimento de bebês

A Shantala é uma técnica de massagem milenar realizada em bebês, descoberta pelo médico francês Frederick Leboyer quando fazia uma visita pela Índia. Popularmente é conhecida devido aos seus benefícios como a tranquilidade, a afetividade entre mãe e filho e o fortalecimento do vínculo entre eles. Através dela farei uma breve apresentação de sua origem e seus métodos, buscando apresentar a afetividade na infância, as principais teorias que perfazem a relação psíquica e motora no primeiro ano de vida, abordando o sistema sensorial e as interfaces com a pele, musculatura e linguagem corporal.

Propriedade antioxidante de compostos fenólicos: importância na dieta e na conservação de alimentos

Living organisms are constantly subjected to the action of free radicals, which are one of the causes of oxidation reactions, because they have on free electron, what makes it very reactive. They are products of organism reactions or they are produced by exogenous factors, such as tobacco. Fatty acids are the most vulnerable target, and may suffer lipid peroxidation, what affects the cell structure. Cardiovascular diseases, cancer and diseases of aging are occurrence of these reactions in the organism related. The aliments are also subjected to suffer oxidation reactions, what make them unfit for consumption and decreasing the useful life. Synthetics antioxidants are used as aliments preservatives, but they present some toxicity for the organism. Studies for the utilization of natural antioxidants have gained more importance in recent decades, due to the conservation potential and low toxicity. Phenolics compounds are largely present at the vegetable kingdom and they present high antioxidant potential due to the neutralization and kidnapping of free radicals capacity. These compounds are used by the industry at the aliments conservation, specially the phenolics acids. The consumption of aliments rich in phenolic compounds, such as teas, wines and fruits are low incidence of degenerative diseases related. This study consists in a bibliographic revision that covers these compounds importance in diet and at the food conservation, and the methodologies and difficulties in the extraction process due to variety of molecules of this group.

Alta pressão hidrostática: tecnologia promissora na conservação de alimentos

Descoberta desde 1889 por Hite, a alta pressão hidrostática tem ganhado cada vez mais espaço na indústria de alimentos nos últimos vinte anos. Com todas as vantagens a ela atribuída, essa tecnologia vem para suprir um mercado onde o consumidor exige um alimento seguro e de qualidade cada vez maior. Uma alternativa aos tratamentos térmicos convencionais, a alta pressão hidrostática não somente se sobressai pela sua eficiência tecnológica, oferecendo conservação de atributos sensoriais e nutricionais dos alimentos, como é capaz de proporcionar alimentos seguros microbiologicamente, conferindo uma maior qualidade aos produtos quando comparada a outros tratamentos. Esta revisão sistemática de literatura teve como objetivo discutir a aplicação da alta pressão hidrostática na indústria alimentícia e seu papel como uma tecnologia promissora. A metodologia consistiu em selecionar textos científicos específicos sobre o assunto a partir da pesquisa bibliográfica em banco de dados eletrônicos e livros. Quatro livros e nove textos científicos foram selecionados, entre o período de 2002 e 2014. Conclui-se com esta revisão sistemática de literatura que a alta pressão hidrostática apresenta um futuro promissor na indústria de alimentos. No entanto, pesquisas são necessárias para um estabelecimento de padrões de valores atribuídos ao processo (como pressão, tempo e temperatura, por exemplo) especificamente para cada produto submetido à tecnologia

Para além do espaço doméstico: o Programa de Aquisição de Alimentos e a visibilização do trabalho feminino nos assentamentos rurais de Presidente Venceslau-SP

This paper presents reflections on a survey on the participation of women seated in the Food Acquisition Program in the city of Wenceslas President / SP. From discussion of the issue of gender in the Brazilian countryside and along the beneficiary populations of land reform policies, evaluates the invisibility of the economic contribution of women - with generally restricted operations to the care of household activities and production for self - which is changing both due to the mobilization of women as the different public policies implemented in the last decade. One of these, the Food Acquisition Program (PAA) is analyzed in its operation. Although not gestated for this specific purpose, this program has contributed to the visibility of women's productive work in the settlements.
