Abstract: the objective of this study was to verify if hyperthyroidism potentiates the osteopenia lactational. 24 adult female rats were distributed in four groups: euthyroid no lactating (control), euthyroid lactating, hyperthyroid no lactating and hyperthyroid lactating. 20 days after gestation, all the animals were necropsied. the thoracic and lumbar vertebrae, the femur and tibia were decalcified and processed for histomorphometric analysis. the euthyroid lactating group presented intense osteopenia in the studied bones. in the hyperthyroid no lactating group, there was not any change in trabecular bone percentage in none of the analyzed bone. in the hyperthyroid lactating group, there was osteopenia in the tibia and femur, similar to the one in the euthyroid lactating group. but the trabecular bone percentage in all the vertebral bodies was significantly larger in comparison with the euthyroid lactating group. it was concluded that the hyperthyroidism does not potentiate the osteopenia lactational in female rats, but it minimizes the vertebral osteopenia once it stimulates the osteoblastic activity.
Predi??o de fra??es digestíveis e valor energético de subprodutos agrícolas e agroindustriais para bovinos
Azevêdo, José Augusto Gomes;Valadares Filho, Sebasti?o de Campos;Detmann, Edenio;Pina, Douglas dos Santos;Pereira, Luiz Gustavo Ribeiro;Oliveira, Karla Alves Magalhes de;Fernandes, Henrique Jorge;Souza, Natália Krish de Paiva;

Abstract: the objective of this work was to evaluate the equations adopted by the nrc and detmann to estimate the energy content of agricultural and agroindustrial byproducts. it was evaluated byproducts of pineapple, cocoa, palm oil, beans, sunflower, guava, cassava bark, cassava stem, raw cassava, papaya, mango, passion fruit, turnip and corn gluten meal. all animals received corn silage and the mixture urea/ammonium sulfate (9:1) so rations with the two levels of each byproduct remained isonitrogenous. among the models for digestible crude protein prediction (cpad), detmann 2 model presented difference by the hypotheses test for joint null while estimates by the nrc and detmann 1 models were similar to those obtained by in vivo observations. for digestible ether extract (eead), digestible non-fibrous carbohydrates (nfcad) and digestible neutral detergent fiber (ndfd), the estimates obtained by the model proposed by the nrc differed, by the test of significance of hypotheses of joint null, to in vitro observations and the best adjustment was obtained by the model suggested by detmann, having as a consequence, the value. however, among all the digestible fractions, ndfd presented the greatest dispersion of points regarded to equality line. nrc and detmann models can be considered as efficient in predicting total digestible nutrients (tdn) and digestible energy (de) because the estimates do not differ from the observed values, however they also present great dispersion of the points regarded to equality line. it is recommended to use the models proposed by detmann for predicting digestible fractions of crude protein, ether extract and non fibrous carbohydrates on agriculture and agroindustrial byproducts.
Calcium bentonite as reinforcing nanofiller for thermoplastic starch
Magalhes, Natália F.;Andrade, Cristina T.;
Journal of the Brazilian Chemical Society , 2010, DOI: 10.1590/S0103-50532010000200003
Abstract: glycerol-plasticized corn starch materials (tps), reinforced with calcium bentonite, were prepared by melt extrusion. scanning electron microscopy was used to visualize extrudates morphology. the effects of clay content and of glycerol content on physical properties of extrudates were evaluated. as determined by x-ray diffraction, the increase in glycerol content led to materials with higher b-type crystallinity. addition of clay resulted in hybrid materials with improved properties in relation to tps alone, even after conditioning at a high relative humidity for 90 days. x-ray diffraction was also used to evaluate clay intercalation within the polymeric matrix, before and after conditioning. results from tensile tests suggested a high degree of exfoliation.

Abstract: O uso do álcool e o estresse s o temas complexos e muito pouco explorados. O objetivo do estudo foi identificar o uso de álcool e os níveis de estresse entre participantes de uma campanha de saúde na estrada. A pesquisa foi realizada em abril de 2008, em uma rodovia de Ribeir o Preto-SP. O desenho metodológico é do tipo descritivo da abordagem quantitativa. A coleta de dados ocorreu por meio de um questionário com perguntas fechadas sobre o uso do álcool,os motivos para o seu consumo e os sintomas do estresse. A amostra foi composta por 91,2% participantes da campanha, que em maioria era do sexo masculino, adultos, de cor branca, casados/amasiados, com baixo nível de escolaridade, motoristas de caminh o, católicos e procedentes da regi o Sudeste. Em rela o ao uso do álcool, 71,2%fizeram ou fazem uso de bebidas alcoólicas. Um ter o afirmou que a raz o para o consumo de bebida alcoólica foi o relaxar e 15% apresentaram níveis de estresse aumentado. Dentre os principais sintomas, os problemas familiares, os físicos e os financeiros foram os mais assinalados. Conclui-se que a identifica o precoce de ambos os problemas é fundamental para que a es preventivas efetivas possam ser planejadas a essa popula o.

Abstract: INTRODU O: O histórico familiar positivo para a doen a renal cr nica (HF+) é um fator de risco para o surgimento e desenvolvimento dessa doen a. Desta forma, é importante avaliar tra os que possam estar correlacionados à predisposi o familiar para a doen a renal cr nica. OBJETIVO: Avaliar a modula o auton mica, pela variabilidade da frequência cardíaca, de indivíduos com HF+. MéTODOS: Foram avaliados nove indivíduos saudáveis com HF+ e 22 indivíduos saudáveis com histórico familiar negativo para doen a renal cr nica (Grupo HF-), pareados por idade (27 ± 6 vs. 26 ± 4 anos; p = 0,39, respectivamente). A frequência cardíaca foi medida continuamente pelo cardiofrequencímetro Polar S810i durante 10 minutos de repouso na posi o supina. A Variabilidade da Frequência Cardíaca (VFC) foi avaliada pelos índices do domínio do tempo, média dos intervalos RR (MNN), desvio padr o dos intervalos RR (SDNN), raiz média quadrática das diferen as de intervalos RR sucessivos (RMSSD) e percentual de intervalos RR com diferen a de dura o maior que 50 ms (pNN50), e pelos domínios de baixa frequência (BF), alta frequência (AF) e raz o baixa/alta (BF/AF). Os exames laboratoriais foram realizados após jejum de 12 horas. Os resultados s o expressos como média ± desvio padr o, adotando como significativo p < 0,05. RESULTADOS: Os grupos HF+ e HFforam semelhantes em rela o à estimativa da taxa de filtra o glomerular (p = 0,49) e frequência cardíaca (p = 0,68). Os grupos HF+ e HF- n o apresentaram diferen as significativas em rela o aos índices da variabilidade da frequência cardíaca MNN; SDNN, RMSSD, pNN50, Potência total; BF; AF u.n e raz o BF/AF. CONCLUS O: A modula o auton mica cardíaca está preservada em indivíduos saudáveis com HF+. INTRODUCTION: The positive family history of chronic kidney disease (FH+) is a risk factor for the appearance and development of this disease. Thus, it is important to assess traits that may be related to familial predisposition to chronic kidney disease. OBJECTIVE: To evaluate the autonomic modulation by heart rate variability in individuals with FH+. METHODS: We studied 9 health subjects with FH+ and 22 health subjects with negative family history for chronic kidney disease (FH-) matched for age (27 ± 6 vs. 26 ± 4 anos; p = 0.39, respectively). Heart rate was measured continuously by the Polar S810i for 10 minutes of rest in the supine position. The heart rate variability was evaluated by the time domain, mean of NN intervals (MNN), standard deviation of the NN intervals (SDNN), root mean squared differences of successive NN intervals (R
Sincretismo e quest?o racial: rela??es lexicais e representa??es conflitantes em dois jornais e duas revistas impressas brasileiras

DELTA: Documenta??o de Estudos em Lingüística Teórica e Aplicada , 2010, DOI: 10.1590/S0102-44502010000100002
Abstract: in the field of social sciences, especially anthropology, syncretism has often been focused on as a research topic. in the field of linguistic studies, there is very little or apparently no research on the issue being carried out in brazil. this article aims at filling in this gap in linguistic studies. it sets out from an analysis of the lexical item syncretism as culturally relevant for the study of discourses on the racial issue in brazil, as mediated by the press. the theoretical background of critical discourse analysis and some tools of corpus linguistics are combined in order to investigate lexical relations constructed with the word sincretismo in two newspapers and two feature magazines. some of the results suggest there is a conflict between different religious discourses and a tension in the wider discourse of racial democracy in brazil.
