Phocine distemper virus in seals, East Coast, United States, 2006

In 2006 and 2007, elevated numbers of deaths among seals, constituting an unusual mortality event, occurred off the coasts of Maine and Massachusetts, United States. We isolated a virus from seal tissue and confirmed it as phocine distemper virus (PDV). We compared the viral hemagglutinin, phosphoprotein, and fusion (F) and matrix (M) protein gene sequences with those of viruses from the 1988 and 2002 PDV epizootics. The virus showed highest similarity with a PDV 1988 Netherlands virus, which raises the possibility that the 2006 isolate from the United States might have emerged independently from 2002 PDVs and that multiple lineages of PDV might be circulating among enzootically infected North American seals. Evidence from comparison of sequences derived from different tissues suggested that mutations in the F and M genes occur in brain tissue that are not present in lung, liver, or blood, which suggests virus persistence in the central nervous system.

Demonstration of antibodies in archival sera from Canadian seals reactive with a European isolate of phocine distemper virus

Sera from seals infected during the 1988 European epizootic of phocine distemper virus and sera from Canadian seals collected since 1972 have been tested for the presence of antibodies to morbillivirus. Approximately one third of the Canadian sera have been shown to contain anti-morbillivirus antibodies; the possibility that these populations of seals provided a source of infection for European seals is discussed.

The picture of Dorian Gray: beleza, arte, representação

A escolha da obra The Picture of Dorian Gray para objecto de uma análise literária de pendor retórico-estilístico é, acima de tudo, fruto de um gosto muito pessoal. Partindo da leitura rigorosa da obra em questão, concentrámo-nos inicialmente no particular de forma a tentar chegar a características distintivas da produção literária de Wilde. Esta afigurou-se-nos como a melhor estratégia para atingir o objectivo que nos propúnhamos: reconhecer a existência de um padrão específico na escrita do autor e estabelecer a forma como esse padrão exemplifica uma determinada época literária. E assim foi possível descortinar que Oscar Wilde dá ao mundo um único romance onde são profundamente explorados os ideais da Arte recriada, da Beleza reabilitada e das suas Representações teatrais. The Picture of Dorian Gray abre vários precedentes literários, de entre os quais se destaca a coragem de assumir na forma os preceitos convencionados pelos estetas para a vida quotidiana. Os leitores conquistados por tais técnicas são recompensados com a sensação por vezes indefinível de terem apreciado o mais recôndito da alma humana.
