Diversidade de microrganismos indicadores utilizados na avaliação da contaminação fecal de areias de praias recreacionais marinhas: Estado atual do conhecimento e perspectivas

Although the quality of sea recreational waters is already monitored by programs implanted in some Brazilian states, including the State São Paulo, little attention has been given to beach sands, which have been disregarded from the point of view of public health. However, this panorama is changing in recent years due to an increasing number of cases of mycoses and bacterial infections affecting people who frequent beaches and use sands as recreation places. This has caused greater concerns with the contamination of this environment, also measurable by the increase of the number of scientific works on sediments and recreational beach sands microbiota. Currently one knows that in general these sediments contain more microorganisms than the water and are therefore potential sources of contamination of human beings by pathogenic microorganisms. The results of works carried through in some countries are worrying, and have demonstrated the necessity of establishing standards and limits so that monitoring programs of the microbiological quality of beach sands are implanted. Such concern is especially high in Brazil, a country of a tropical climate where thousands of beaches, used for recreation, extend for almost eight thousand kilometers of the coast. In the context of Baixada Santista, studies carried through have shown that in certain situations beach sands can contain more microorganisms than waters and may be a risk to the health of users.

Concepções de surdez: A visão do surdo que se comunica em língua de sinais

At this time, diverse views on deafness are present in society. Such views, in general, arecharacterized by theoretical disputes between communicative possibilities - either oral or gestural - based onthe importance of having appropriated oneself of a language code for the development of language, which isessential in the constitution of subjectivity of human beings. Thus, this study aimed to identify the conceptionsof deaf people had about their condition. To collect the data we used semi-structured interviews, applied toten participants who were deaf adult users of the Brazilian Sign Language - Libras. The interviews were taped,transcribed and subjected to content analysis. The results indicate that the conceptions of deafness constitute amultifaceted view on this condition, infl uenced by social relations throughout each person's life trajectories. Theresearchers perceived that learning Libras enabled deaf persons to constitute their own assertiveness as someonewho is different, with different needs.

Relation between green spaces and bird community structure in an urban area in Southeast Brazil

Increased urbanization typically leads to an increase in abundance of a few species and a reduction in bird species richness. Understanding the structure of biotic communities in urban areas will allow us to propose management techniques and to decrease conflicts between wild species and human beings. The objective of this study was to describe the structure of the bird community in an urban ecosystem. The study was carried out in the city of Taubaté in southeastern Brazil. Point-counts were established in areas with different levels of tree density ranging from urban green spaces to predominantly built-up areas. We looked for a correlation between the richness/abundance of birds and the size of the area surveyed, the number of houses, the number of tree species and the number of individual trees. The results of multiple regression showed that bird richness had a direct relationship with vegetation complexity. The abundance and diversity of tree species were better predictors of bird species than the number of houses and size of the area surveyed. We discuss implications of this study for conservation and management of bird diversity in urban areas, such as the need to increase green areas containing a large diversity of native plant species. © 2011 Springer Science+Business Media, LLC.

Antimutagenic and anticarcinogenic effects of wheat bran in vivo

Previous studies in rodents treated with the pro-carcinogen 1,2-dimethylhydrazine suggested that the consumption of wheat bran protected against DNA damage in the colon and rectum. Based on this information, we evaluated wheat bran as a functional food in the prevention and treatment of colon cancer. We used the aberrant crypt focus assay to evaluate the anticarcinogenic potential of wheat bran (Triticum aestivum variety CD-104), the comet assay to evaluate its antigenotoxicity potential, and the micronucleus assay to evaluate its antimutagenic potential. The wheat bran gave good antimutagenic and anticarcinogenic responses; the DNA damage decreased from 90.30 to 26.37% and from 63.35 to 28.73%, respectively. However, the wheat bran did not significantly reduce genotoxicity. Further tests will be necessary, including tests in human beings, before this functional food can be recommended as an adjunct in the prevention and treatment of colon cancer. © FUNPEC-RP.
