Abstract: background: capillaroscopy is an useful diagnostic tool that is non-invasive, reproducible, able to assess the capillaries in the periungal region and that assists in the differential diagnosis of connective tissue diseases. objetives: the aim of the study was to distinguish chronic cutaneous lupus erythematosus and systemic lupus erythematosus from controls assessed by nailfold capillaroscopy. methods: seventy patients with lupus erythematosus (37 with chronic cutaneous lupus erythematosus and 33 with systemic lupus erythematosus) were studied by the technique of capillary microscopy and compared to 32 controls. results: the presence of ectatic (p=0.027; p=0.001), meandering (p=0.001; p=0.007), corkscrew capillaries (p=0.011; p=0.005) and nailfold bleeding (p=0.004; p=0.001) distinguished between the two groups of patients (chronic cutaneous lupus erythematosus and systemic lupus erythematosus) from controls. the variable meandering loops could be predictive for systemic lupus erythematosus (or=8.308). the independent variables ectatic loops (or=12.164) end nailfold bleedings (or=5.652) were predictive for chronic cutaneous lupus erythematosus. conclusions: capillaroscopy can help in the management of patients, since the presence of typical capillaroscopic abnormalities seems to be related to the development of lupus erythematosus. the independent predictive variables for systemic lupus erythematosus were meandering loops, and, for chronic cutaneous lupus erythematosus, ectasic loops and nailfold bleedings.

Ronaldo de Carvalho Augusto, Gabriela Friani, Maurício Carvalho de Vasconcellos, Maria de Lurdes de Azevedo Rodrigues, Clélia Christina Mello-Silva
Open Journal of Veterinary Medicine (OJVM) , 2015, DOI: 10.4236/ojvm.2015.56017
Abstract: Background: Two aspects need to be considered for schistosomiasis control: morbidity and transmission. In this context, many soluble substances have been tested and Euphorbia milii latex is one of the most promising Brazilian molluscicides. Phytochemical studies involving simulation of the applicability of this latex on all aquatic forms of the S. mansoni life cycle are rare in the literature. The aim of this work was to evaluate the effect of E. milii latex on S. mansoni in the egg, miracidium and different developmental stages in Biomphalaria glabrata. Methods: The laboratory study was designed to simulate the different forms of exposure of the life cycle stages of S. mansoni to the LC50 of E. milii latex; we tested the exposition from four situations of S. mansoni contact with the latex and observed the exposure on different snails’ infection stage too. All snails were analyzed weekly for cercarial shedding and reproductive biology. Results: The results showed that contact of S. mansoni eggs and miracidia with the LC50 of E. milii negatively influenced the development of the parasite life cycle in the intermediate host, with consequent reduction of cercarial shedding. The exposure of infected snails affected the reproductive biology and cercarial shedding in all intra-mollusk development stages of S. mansoni, but the reduction was greater in the first, fourth, fifth, sixth, seventh and eighth weeks of infection. The LC50 of E. milii latex had toxic action on eggs and miracidia, and the number of cercariae shed by snails during the study period declined by about 80%. Conclusions: We can conclude that the use of natural biodegradable compounds containing low concentrations of substances already characterized as having eco-toxico- logical potential can be an important tool to reduce the transmission of Schistosomiasis.

Abstract: Inova o tornou-se um tema estratégico na Administra o, mas no Brasil ainda é restrita como fator de estudo. Isso se dá pelas características do meio, que visualiza a inova o como uma vantagem competitiva, um segredo da organiza o. Essa situa o levou ao desenvolvimento desta pesquisa, que prop s verificar a constitui o de um ambiente inovador e a maneira pela qual elementos de cultura se relacionam. A partir da metodologia utilizada, observou-se, pela análise dos fatores do ambiente, que o ambiente inovador foi encontrado nas 7 organiza es analisadas. Os elementos de cultura observados s o: valores, cren as e pressupostos, ritos, rituais e cerim nias, estórias e mitos, tabus, heróis, comunica o e artefatos e símbolos. Na etapa de valida o, os mesmos elementos foram encontrados, com menor incidência dos artefatos e símbolos. Dessa forma, o pressuposto levantado na pesquisa p de ser confirmado: organiza es inovadoras possuem elementos de cultura que podem estar propiciando e incentivando o desenvolvimento de inova es. Innovation has become strategic in business administration, however in Brazil it is still viewed as a competitive advantage, an organizational secret. Therefore study verified how an innovative atmosphere is formed within a business as well as how the elements of culture are related. Based upon the methodology used, an innovative ambient was found in the 7 organizations by means of an analysis of aspects of the environment. Elements that form the company culture and that were found related to innovation were: values, faiths and presuppositions, rites, rituals, ceremonies, histories, myths, taboos, heroes, communications, artifacts and symbols. During validation these same elements were found, although with a smaller incidence of artifacts and symbols. Results confirm the research hypothesis that innovative organizations also possess cultural elements that may be propitiating and motivating development of innovations.
