Abstract: a prospective study was undertaken in 1,520 children less than 15 years of age in s?o josé de ribamar, maranh?o, brazil, from june 1994 to january 1995, to evaluate the prevalence and characteristics (socioeconomic, environmental, and behavioral) associated with infection by leishmania chagasi. montenegro skin test (mst) and enzyme-linked immunosorbent assay (elisa-rk39 and crude) test were used to detect infection. the statistical analysis used the c2 test with yates correction and a p value less than 0.05 was considered statistically significant. prevalence of infection was 61.7% as measured by mst, 19.4% according to elisa (rk39), and 19.7% by elisa (crude). association was detected between leishmaniasis in the family, water supply, application of insecticide, and infection by l. chagasi using mst. no association with infection by l. chagasi was detected using elisa rk39 or crude. more effective control measures are needed to reduce prevalence and to detect asymptomatic cases in this high percentage of infected children.

Abstract: comparative study regarding igg and ige anti-leishmania as markers of infection and illness among residents of a visceral leishmaniasis visceral leishmaniasis endemic area, s?o luis, ma in the period from may 1999 to may 2000. all the 1,016 individuals younger than 16 years old were tested for the presence of igg by elisa. a total of 174 (17,1%) children revealed a positive igg test and 4 children showed symptoms of classical visceral leishmaniasis during the time of the survey: 85 ige anti-leishmania elisa tests with positivity of 43,5% were realized. in this sample, all 7 children with past-visceral leishmaniasis in the sample were igg positive and 4 (57,1%) were ige positive, even after a 7 year post treatment period. three children with current visceral leishmaniasis were evaluated, and all of them were positive for both tests. the detection of antileishman ige antibodies presented as a good marker for infection by leishmania chagasi in endemic areas but not as a disease marker.

Abstract: Estudo comparativo de anticorpos IgG e IgE antileishmania como marcadores de infec o e doen a em área endêmica de leishmaniose visceral na ilha de S o Luis, MA no período de maio de 1999 a maio de 2000. A casuística foi composta de 1.016 menores de 16 anos. Destes, foram randomizados 85 para dosagem de IgE antileishmania pelo ELISA. A prevalência de soropositividade por IgG foi de 17,1% (174 menores) e 0,4% da popula o evoluiu para leishmaniose visceral doen a. A positividade para IgE antileishmania, foi de 43,5% dos 85 indivíduos estudados. Dos 7 casos de calazar no passado analisados, observou-se que todos apresentavam positividade para IgG e 4 (57,14%) permaneciam positivos para IgE, mesmo 7 anos após a cura. Os 3 menores com leishmaniose visceral doen a, apresentaram positividade para IgG e IgE antileishmania. A detec o de IgE antileishmania demonstrou ser marcador de infec o para Leishmania chagasi em área endêmica, n o sendo entretanto, marcador de doen a.

Comment to: Corrections to the fine structure constant in the spacetime of a cosmic string from the generalized uncertainty principle
Geusa de A. Marques
Physics , 2007, DOI: 10.1016/j.physletb.2006.06.012
Abstract: In the paper [F. Nasseri, Phys. Lett. B 632 (2006) 151--154], F. Nasseri supposed that the value of the angular momentum for the Bohr's atom in the presence of the cosmic string is quantized in units of ?. Using this assumption it was obtained an incorrect expression for Bohr radius in this scenario. In this comment I want to point out that this assumption is not correct and present a corrected expression for the Bohr radius in this background.
Analogue of superradiance effect in acoustic black hole in the presence of disclination
Geusa de A. Marques
Physics , 2007,
Abstract: In this paper we invstigate the possibility of the acoustic analogue of a phenomenon like superradiance, that is, the amplification of a sound wave by reflection from the ergo-region of a rotating acoustic black hole in the fluid "draining bathtub" model in the presence of a desclination be amplified or reduced in agreement with the value of the deficit angle.

Abstract: As políticas públicas s o formuladas com o intuito de promover a es que visem ao bem-estar social e a melhoria da qualidade de vida da popula o. Saúde é o gozo pleno das fun es organicas, físicas e mentais de um ser humano. Cuidar, preservar e ampliar a longevidade da vida é a importante tarefa da fun o saúde. Esta pesquisa tem como objetivo geral analisar a eficiência dos gastos públicos com assistência hospitalar nos estados brasileiros nos anos de 2009 e 2010. Foram utilizadas as pesquisas descritiva, bibliográfica, quantitativa e qualitativa. A coleta de dados foi realizada nos sítios da Secretaria do Tesouro Nacional, FINBRA, DATASUS e Sistema da FIRJAN. Os resultados revelaram que dentre os 23 estados pesquisados 6 deles (Acre, Amapá, Paraná, Roraima, S o Paulo e Tocantins) foram considerados eficientes pela observa o de seus escores em 2009, e, em 2010, a eficiência foi visualizada em 7 estados (Acre, Amapá, Minas Gerais, Paraná, Roraima, S o Paulo e Tocantins).

Abstract: Spirulina platensis (SPI) is a microalga with a high content of functional compounds, such as phenolics, phycocyanins and polysaccharides that has been shown to have antioxidant, anti-inflammatory, hypoglycemic, neuro-protective and immunomodulatory effects. The objectives of the present work were to study the possible effects of SPI treatment on the glycemic-lipid profile, oxidative stress, lipid peroxidation and cardiac performance in diabetic rats. Diabetes was induced by streptozotocin (STZ) in male Wistar rats. In diabetic animals SPI, at a dose of 50 mg/kg/day, reduced lipid peroxidation, nitrite levels and lipids in plasma and tissues. SPI exhibited an effective improvement on +dP/dT and dP/dT in non-diabetic rats. This study showed that SPI significantly suppressed nitrite generation and lipoperoxidation in the hearts of diabetic animals, as well as an improvement in the cardiac function in control SPI-treated rats which is consistent with several studies that demonstrated the protective effect of antioxidants on oxidative stress-mediated injury caused by reactive oxygen species (ROS) produced in diabetic myocardial tissues.

Abstract: beh?et's disease (bd) is a systemic vasculitis in which thrombosis is a common clinical complication. we report a case of a pregnant woman with bd and the presence of heterozigous factor v, previous erisipela lesions and family history of thromboembolisms. her bd evolved to remission during gestation, nevertheless, low molecular weight heparin was maintaned during pregnancy. in this report, we discuss the thrombophilic aspects in pregnant women with bd.
