Objective: To model changes in body mass index (BMI), including its stability, and to investigate the association between physical activity, 1-mile run/walk and levels of gross motor coordination and BMI during 5 consecutive years. Design: A longitudinal study of children 6 years of age at baseline followed at annual intervals over 5 years. Subjects: A total of 285 children (143 boys and 142 girls) were enrol...
A criação de suínos em escala industrial resulta em intensa produção de dejetos nas propriedades rurais, conseqüências que se manifestam no solo, no ar, na fauna, na flora e no ambiente socioeconômico; neste contexto, externalidades negativas podem interagir com outras variáveis ou ações econômicas representadas, por exemplo, pelos gastos com a conservação do meio ambiente e, em particular, em Mato Grosso, pela...
Colheu-se sangue de sete suínos infectados com ovos de Taenia solium, semanalmente, durante 140 dias, para realizar ELISA no soro, utilizando antígeno de escólex (Es-Tso) de C. cellulosae. Em todos os animais, após o 21º dia pós-infecção, houve incremento significativo de anticorpos IgG, que assim se mantiveram até o final do experimento. A sensibilidade do ELISA variou entre 87,5 e 100%. À necropsia, foram ide...
O presente trabalho representa a primeira análise das atividades analgésica e antiinflamatória do extrato bruto hidroalcoólico do zoantídeo Palythoa caribaeorum. Foram realizados os testes de Writhing induzido por ácido acético (1%, 10 mL.kg-1 i.p.) e da chapa quente em camundongos para avaliar o efeito analgésico; e o teste de edema de pata de rata induzido por carragenina para avaliar a atividade antiinflamat...
We report on the progress in the study of cascaded GEM and GEM/MHSP gas avalanche photomultipliers operating at atmospheric pressure, with CsI and bialkali photocathodes. They have single-photon sensitivity, ns time resolution and good localization properties. We summarize operational aspects and results, with the highlight of a high-gain stable gated operation of a visible-light device. Of particular importanc...
We present recent results on the operation of gas-avalanche detectors comprising a cascade of gas electron multipliers (GEMs) and Mico-Hole & Strip Plate (MHSP) multiplier operated in reversed-bias (R-MHSP) mode. The operation mechanism of the R-MHSP is explained and its potential contribution to ion-backflow (IBF) reduction is demonstrated. IBF values of 4×10-3 were obtained in cascaded R-MHSP and GEM multipl...
The main objective of the present study was to evaluate the diagnostic value (clinical application) of brain measures and cognitive function. Alzheimer and multiinfarct patients (N = 30) and normal subjects over the age of 50 (N = 40) were submitted to a medical, neurological and cognitive investigation. The cognitive tests applied were Mini-Mental, word span, digit span, logical memory, spatial recognition spa...
