ABSTRACT
Essential oils derived from plants used as condiments represent a large group of natural antimicrobials. Extracts and essential oils from plants have been shown to be efficient in controlling the growth of a wide variety of microorganisms, including filamentous fungi, yeasts and bacteria. Practical uses of these activities are suggested in humans and animals, as well as in the food industry. This study aimed to evaluate the basal basil essential oil (Ocimum basilicum L.) cytotoxicity in NCTC Clone 929 cell line, mouse connective tissue cells (CCIAL 020), which were seeded in Petri dishes and incubated for 48 hours To to form the cell monolayer. For the this test accomplishment of this test, we counted with the collaboration of the Nucleus of Cell Cultures - NCC of the Adolfo Lutz Institute, of the city of São Paulo-SP. The culture medium used is the solid coating medium, and fragments of the samples fragments are were placed on this coating medium and the plates were again incubated for 24 hours. The Biological Reactivity Degree (GR) index, which is the area not stained by the vital dye, is were observed macro and microscopically. Samples were tested in quadruplicates on separate plates. ThusThereunto, the test result showed that the essential oil was cytotoxic in the cell line studied, and that the future work in pharmacology and toxicology needs to be performed to better standardize the therapeutic dose, which is not cytotoxic as the pure oil behaved.o assess the attitude and practice of dental professionals towards using of advance Radiographic technique.
ABSTRACT
Several variables have been used to indicate conflicts between socioeconomic interests and biodiversity conservation. Thus, efforts to minimize biodiversity losses are being based on the analysis of such conflicts, since there is more and more evidence that important sites to conservation could support high population densities and their impacts. However, in the Cerrado this might not be true due to the technological progress associated with human settlement. Consequently, the aim of this paper was to verify whether human population density (H) revealed conservation conflicts in the Cerrado. Through multiple regressions of Emberizidae richness (spilt into three groups according to their occurrence) as a biodiversity index and land-use variables, we verified that human population density was not the best indicator of conservation conflicts. Modern agriculture and cattle ranching indexes were the best indicators for the three Emeberizidae groups. Thus, the use of H as model selection to designate conservation units can be a mistake for Emberizidae species richness. In the Cerrado region, variables linked to modern agriculture and cattle ranching should be taken into account during systematic conservation planning
Diferentes variáveis têm sido utilizadas para indicar conflitos entre interesses socioeconômicos e conservação da biodiversidade. Neste contexto, esforços para amenizar a crescente perda de diversidade estão sendo baseados nas análises dos conflitos entre conservação e desenvolvimento humano, uma vez que existem, cada vez mais, evidências de que as áreas de maior importância para a conservação podem também apresentar elevadas densidades populacionais humanas. Contudo, para o Cerrado, isso pode não ser verdade em decorrência dos avanços tecnológicos associados à ocupação humana. Assim, o objetivo deste trabalho foi verificar se a densidade populacional humana (H) revela conflitos de conservação no Cerrado. Utilizou-se, como medida de biodiversidade, a riqueza de espécies de emberizídeos (aves: Passeriformes), divida em três grupos distintos, de acordo com a extensão de ocorrência das espécies e variáveis ligadas ao modo de ocupação do bioma. Verificou-se, por meio de regressões múltiplas, que a densidade humana não foi o melhor indicador de conflitos de conservação. Índices ligados à agricultura moderna e à pecuária foram melhores indicadores para os três grupos de espécies. Deste modo, a partir da riqueza de emberizídeos, a utilização de H, em modelos de seleção de unidades de conservação pode ser equivocada. Para o Cerrado, variáveis ligadas à agricultura moderna e à pecuária
