ABSTRACT
O objetivo deste estudo foi avaliar a ocorrência da infecção pelo vírus Maedi-Visna em ovinos criados nas microrregiões de Botucatu, Campinas, Piedade e São Paulo do Estado de São Paulo. As amostras de soro sanguíneo foram colhidas de 226 ovinos e foi realizada a técnica de imunodifusão em gel de ágar para a detecção de anticorpos antivírus Maedi-Visna e verificou-se que nenhuma das amostras testadas foi sororeagente. Dessa forma, faz-se necessário um estudo mais amplo no estado, a fim de se confirmar a baixa ocorrência e importância da enfermidade no estado.
Survey for antibodies against maedi-visna virus in sheep in the regions of Botucatu, Campinas, São Paulo and Piedade, state of São Paulo, Brazil. The purpose of the study was to evaluate the occurrence of infection with maedi-visna virus in sheep raised in the regions of Botucatu, Campinas, Piedade and São Paulo, state of São Paulo, Brazil, that showed symptoms of the disease. Blood serum samples collected from 226 sheep were submitted to the agar gel immunodiffusion technique for detection of antibodies against maedi-visna virus, and none of the samples tested was serum reactive. In conclusion, the maedi-visna virus has low frequency in animals raised in the regions studied.

Cães capturados nas ruas de quatro municípios do estado de São Paulo foram examinados para estudar a prevalência de Hepatozoon canis. Dos 222 animais, 13 (5.9 por cento) encontravam-se infectados. Exames hematológicos realizados em nove animais evidenciaram três com anemia e um com leucocitose. A única alteração encontrada nos exames bioquímicos foi hiperglobulinemia.

ABSTRACT
En microsomas intactos, dos flavonas purificadas a partir de hojas de Bauhinia megalandra, inhiben la actividad de la glucosa 6-fosfatasa en una manera dependiente de su concentración. Ambas flavonas incrementan el valor del Km para glucosa-6-fosfato, sin modificar el valor de Vmax. Los resultados permiten concluir que ambas flavonas inhiben competitivamente al transportador de glucosa-6-fosfato (T1), sin afectar ni a la subunidad catalítica ni al transportador de fosfato/pirofosfato (T2) del sistema de la glucosa-6-fosfatasa. Las flavonas inhiben la capacidad neoglucogénica de rebanadas de hígado incubadas en buffer Krebs-Ringer bicarbonato suplementado con lactato y albúmina saturada con oleato. La inhibición que ejercen las flavonas sobre el transportador T1 del sistema de la glucosa-6-fosfatasa microsomal, puede explicar la disminución de la capacidad neoglucogénica de las rebanadas de hígado, lo cual podría reducir la concentración de glucosa en pacientes diabéticos

Why does a peacock have a beautiful train, while a peahen is sober without such flamboyance? Darwin proposed the theory of sexual selection to explain the differences between the sexes of the same species. Recently the study of sexual selection has been one of the most flourishing areas in evolutionary biology. However, the theory met with great resistance from biologists since the publication of the idea and the history of the theory included a lot of misunderstanding and confusion. There are several reasons for this. First, classical Darwinism failed to recognize social competition as an important selective force. Second, the good-for-the-species argument, which persisted in the days after Darwin, made the sexual selection argument more difficult to under-stand. Compared to the discussions on animals, Darwin's argument on human sex differences is not satisfactory. The reason probably lies in the debate over human racial differences which prevailed in the 19th century.

A total of 622 and 110 commensal and forest rodents and shrews was examined in the urban and rural areas of Chanthaburi Province, Thailand. A higher density of commensal animals was found in urban than rural areas. Five enteropathogenic bacteria, and four helminth species of significant medical importance were collected. The Oriental rat-flea, X. cheopis was found prevalent among these animals. The findings of adult A. cantonensis worm in S. murinus the first reported case of the parasite developed into adult in an abnormal host.
