Participação social e designação de espécie-bandeira: ações complementares à conservação de um parque estadual em área urbana

Facing environmental problems the planet appears several alternative preventive and control on behalf of the equation between development and environmental protection. One of the alternatives implemented in Brazil to conservation of biodiversity was the creation of protected natural areas regulated by the National System of Conservation Units (SNUC). This is an integrated study of the Comunication / Environmental Conservation, which prioritizes social participation as a complementary in the conservation process, the particular case of the Dunas do Natal State Park, the first conservation area in Rio Grande do Norte, for full protection. It takes into account the roles environmental, scientific and Park, which harbors a unique biodiversity, including endemic species and the fact being located in an urban area. It proposes the use of two complementary instruments, such as strategies for conservation. Considering the various individual experiences, it was analyzed the perception that the community is directly related to the Park. From this promoted the democratization of information about the park, its biodiversity and conservation. As another conservation tool, it was suggested the use of a flagship species for the park, or a body chosen symbol for environmental or social reasons, in order to protect and conserve certain natural environments, from the understanding and co -community participation. In this case, as proposed flag Coleodactylus natalensis species, the lizard-the-litter, to be endemic remnants of Atlantic Forest Park as having the type locality, be one of the smallest species of the world, South America's lowest-dependent shadow of the forest, sensitive to human action and therefore very vulnerable. This suggestion finds support in the degree of public acceptance that interacts directly with the Park, as a result of the evaluation of their perceptions. It was further observed in this study that this symbology to be used in order to promote the democratization of the Park and its biodiversity has an identification result, curiosity and probable involvement of the population with the issues of the Park

A política empresarial: a responsabilidade social como mecanismo de segurança

Neste ensaio, tomamos como problema as ações da política empresarial no Brasil, em específico a política de responsabilidade social das empresas, por entender que existe nessa iniciativa um status de inovação tecnológica que precisa ser interrogado, pois se inscreve no interior de uma racionalidade que objetiva o governo das populações e tem como instrumento técnico, para realizar esse fim, uma sociedade controlada por mecanismos de segurança. Para tanto, partimos da análise de três procedimentos efetivados por alguns projetos sociais desenvolvidos por empresas brasileiras - a pesquisa científica, o protagonismo juvenil e a metodologia participativa. A referência de análise são textos de diversas naturezas, veiculados por esses projetos e disponíveis ao acesso público.

The immune system of insects and the control of some parasitary human diseases

Parasitic diseases in humans, transmitted by insects, affect about 500 million people living mainly in countries of low economic power, the control of these diseases is difficult to carry out, mainly die to social and political problems, enhanced bg the capacity of these organisms to develop resistance to insecticides used to for their destruction.Some recent advances in the area of insect immunology have open the possibility for abetter epidemiological control of these diseases.The immune system of these insects, as well as that of other organisms, have the ability to recognize the infecting parasites and liberate a series of reactions which stop the infection. These reactions involve the circulating cells (hemocytes) against the parasite. These cells have the ability of phagocytize and liberate the production of various humoral factors, neutralizing the infection.Some promising results, obtained by the study of the immune system of malaria-transmitting insects, the sleeping disease, and dengue, are an example of this new sanitary strategy.

Expressed sequence tags from Atta laevigata and identification of candidate genes for the control of pest leaf-cutting ants.

Leafcutters are the highest evolved within Neotropical ants in the tribe Attini and model systems for studying caste formation, labor division and symbiosis with microorganisms. Some species of leafcutters are agricultural pests controlled by chemicals which affect other animals and accumulate in the environment. Aiming to provide genetic basis for the study of leafcutters and for the development of more specific and environmentally friendly methods for the control of pest leafcutters, we generated expressed sequence tag data from Atta laevigata, one of the pest ants with broad geographic distribution in South America. Results: The analysis of the expressed sequence tags allowed us to characterize 2,006 unique sequences in Atta laevigata. Sixteen of these genes had a high number of transcripts and are likely positively selected for high level of gene expression, being responsible for three basic biological functions: energy conservation through redox reactions in mitochondria; cytoskeleton and muscle structuring; regulation of gene expression and metabolism. Based on leafcutters lifestyle and reports of genes involved in key processes of other social insects, we identified 146 sequences potential targets for controlling pest leafcutters. The targets are responsible for antixenobiosis, development and longevity, immunity, resistance to pathogens, pheromone function, cell signaling, behavior, polysaccharide metabolism and arginine kynase activity. Conclusion: The generation and analysis of expressed sequence tags from Atta laevigata have provided important genetic basis for future studies on the biology of leaf-cutting ants and may contribute to the development of a more specific and environmentally friendly method for the control of agricultural pest leafcutters.

Control of parasitic infections among school children in the peri-urban area of Botucatu, Sao Paulo, Brazil

The prevalence of intestinal parasitosis was investigated in a primary school located in Rubiao Junior, a peri-urban district of Botucatu, Sao Paulo state, Brazil, in order to assess the effect of treatment and practical measures of prophylaxis in the control of parasitic infections among 7-to-18-year-old school children of a low socio-economic status. The first series of parasitological examinations included 219 school children, of which 123 (56.1%) were found to be infected with one or more parasite species. Eighty-four children carrying pathogenic parasites were submitted to various anti-parasitic treatment schedules. We re-evaluated 75 (89%) students after 4 to 6 months postchemotherapy. The results indicate that the combination of treatment with prophylactic measures has been successful in the control of parasitic infections, since reinfection rates were generally low (≤5.3%), except for Giardia lamblia infections (18.6%), and a marked reduction on the prevalence rates was observed with a significant percentage of cure (≤73.1%) in children infected with most parasite species. The reasons for the apparent failure in the control of infections caused by Hymenolepsis nana and Strongyloides stercoralis are discussed.
