ABSTRACT
Jambolan is rich in antioxidant polyphenols; however, the bioactivity of these compounds remains poorly investigated. We compared changes in polyphenols and antioxidant capacity by ABTS and FRAP assays of jambolan pulp during in vitro digestion and chemical extraction and evaluated the effects of these changes on oxidative stress in wild and mutant Saccharomyces cerevisiae. Digestion and chemical extraction were performed with enzyme saline solutions, deionized water, and 50% (v/v) aqueous acetone solution. Caffeic, quinic, gallic, and ellagic acids, isomers of myricetin, catechin, and anthocyanins are bioaccessible during gastric digestion. In the duodenum, flavonoids and proanthocyanidins remained stable when the pH changed from acidic to neutral/alkaline, whereas anthocyanins were degraded when exposed to pH 7. In the colon, anthocyanins were not identified. The antioxidant activity of bioaccessible fractions is correlated with non-anthocyanin flavonoids and proanthocyanidins, reflected in the modulation of antioxidant enzymes of S. cerevisiae. The digestion process favors the release of bio-polyphenols from jambolan with preventive, scavenger, and reparative antioxidant action. They also stimulate the production and activity of Sod and Cat, strengthening the endogenous antioxidant system.

Objetivo: relatar a experiência vivenciada diante da observação do comportamento alimentar do autista em um Centro Integrado de Educação Especial da cidade de Teresina, Piauí. O Transtorno de Espectro Autista é uma disfunção caracterizada por falhas no desenvolvimento social e intelectual, afetando o comportamento e repercutindo no convívio social e linguagem. Metodologia: trata-se de um relato de experiência vivenciada por profissionais de saúde diante da observação de tal comportamento durante o lanche no período de janeiro a outubro de 2014. Resultados: no cotidiano de trabalho, na hora do lanche, observam-se as mais variadas reações como recusa ou preferência por certa cor, cheiro, consistência e textura. Resistência a sentar à mesa para comer com outras pessoas, entrar no refeitório e aceitar preparações novas. Conclusão: o Autismo é uma síndrome que compromete todo o desenvolvimento da criança e adolescente, e por esse motivo necessita de uma atenção especial do poder público, profissionais da saúde, familiares e demais pessoas envolvidas.
Objective: report on the lived experience of observing the feeding behavior of autistic in an Integrated Centre for Special Education of the city of Teresina, Piauí. Autistic Spectrum Disorder is a disorder characterized by failures in the social and intellectual development, affecting the behavior and impacting the social interaction and language. Methodology: this is a report of an experience lived by health professionals on the observation of such behavior during the lunch period from January to October 2014. Results: in daily work, at lunchtime, we observe the most varied reactions as denial or preference for a certain color, smell, consistency and texture. Resistance to sit at the table to eat with other people, enter the cafeteria and accept new preparations. Conclusion: autism is a syndrome that affects the whole development of the child and adolescent, and therefore needs special attention from the government, health professionals, relatives and other people involved.

A água de consumo humano é o principal veículo de transmissão de patógenos capazes de causar infecções gastrointestinais, sendo vital o seu controle microbiológico. O presente trabalho teve a finalidade de avaliar a qualidade bacteriológica da água para o consumo humano, quanto à presença de coliformes totais e termotolerantes, em diferentes unidades de alimentação na cidade do Recife (PE), conforme os padrões de potabilidade estabelecidos pela Portaria nº 518 de 2004 do Ministério da Saúde/ANVISA. Foram coletadas quarenta amostras de água em unidades de alimentação, localizadas no entorno da Universidade Federal de Pernambuco e da Universidade Federal Rural de Pernambuco. Foram realizados os testes bacteriológicos para pesquisa de coliformes totais e termotolerantes, conforme o protocolo do APHA (1995). Das amostras analisadas, 62,5 por cento apresentaram coliformes totais e 42,5 por cento, coliformes termotolerantes. De acordo com os resultados obtidos, 62,5 por cento das amostras não estão em conformidade com a legislação vigente.
The water for human consumption is the main vehicle for the transmission of pathogens that are capable of causing enteric parasitic diseases; therefore, its microbiological control is vital. This work had the purpose of evaluating the bacteriological quality of drinking water, in terms of the presence of total and thermotolerant coliforms, in different Feeding Units in the city of Recife, Pernambuco State, according to the potableness standards established by Ordinance No. 518 of 2004 of the Brazilian Ministry of Health/ANVISA. Forty water samples were collected in the Feeding Units located near the UFPE and UFRPE. The bacteriological tests for research on total and thermotolerant coliforms were carried out in accordance with the protocol of APHA (1995). Of the analyzed samples, 62.5 percent presented total coliforms and 42.5 percent thermotolerant coliforms. According to the results obtained, 62.5 percent of the samples are not in compliance with the law in force
