Notes on the Cretaceous invertebrate faunas of Portugal I: a new species of Anadromus (Mollusca, Gastropoda) from the Campanian-Maastrichtian of Taveiro (Coimbra, West central Portugal)

A new species of terrestrial gastropod - Anadromus penai sp. nov. (Fam. Anadromidae) - is described from a set of composite moulds collected in reddish silts and clays of Campanian-Maastrichtian age, found in the lower pan of the Taveiro Formation (Taveiro, Coimbra, West Central Portugal). The known occurrences of this new species are restricted to the type locality. The main differences from other contemporaneous Anadromidae are the profuse spiral sculpture of the body-whorl, with 20-22 sub-equal, close, and regular ribs.

Biological and morphological characteristics of Schistosoma mansoni from Ribeira Valley, State of S��o Paulo, Brazil: I - susceptibility of Biomphalaria tenagophila snail to sympatric S. mansoni strain

In the S��o Paulo State, Brazil, where the Biomphalaria tenagophila is the intermediate host, the Ribeira Valley is an important endemic schistosomiasis mansoni area. During last eleven years there has been intense control measures focusing on schistosomiasis. The efforts have been concentrated in the municipalities of Pedro de Toledo and Itariri. We determined the susceptibility of B. tenagophila to sympatric strain of S. mansoni, both recently isolated from Itariri field. In 1988, this strain was isolated and maintained in the experimental model: Swiss mice - sympatric B. tenagophila. The second generation of the worm was evaluated. The snail were divided in the three groups of 60 snails each. One group was exposed to 1 miracidium and other to 10. The third group was the control. The mortality and the shedding of cercariae were checked during 78 days. After that, the positive snails were observed until they ceased to shed cercariae. The exposed molluscs showed mortality rates of 23% and 31% and infection indexes were of 8% and 60% to 1 and 10 miracidia respectively. The mortality was of 22% in the control group. The periods of shedding cercariae in the two groups were 82 and 104 days. We can conclude that B. tenagophila is an effective intermediate host to the sympatric strain of S. mansoni sympatric strain

Prevalence of HTLV-I antibody among two distinct ethnic groups inhabiting the Amazon region of Brazil

HTLV-I seroprevalences of 3.63% (02/55), 12.19% (10/82) and 13.88% (10/72) were demonstrated among Tiryio, Mekranoiti and Xicrin Amazonian Indians, respectively, by the Western blotting enzyme assay (WBEI). By indirect immuno electron microscopy (IIEM), 2 Tiriyo, 9 Mekranoiti and 6 Xicrin Amerindians were reactive. Of 44 serum samples from Japanese immigrants, none reacted by any of the techniques before mentioned. One, 8 and 6 serum samples from Tiryio, Mekranoiti and Xicrin Indians, respectively, were both WBEI and IIEM positive. Our results strongly suggest that HTLV-I and/or an HTLV-I antigenic variant circulate (s) among populations living in the Amazon region of Brazil.

Shall I compare thee to an old man? A velhice em William Shakespeare e Rug��nio de Andrade

A velhice �� um tema que emerge com frequ��ncia nas obras de William Shakespeare e de Eug��nio de Andrade, sempre num tom disf��rico. Em ambos, a ��ltima das sete idades do ser humano, acarreta uma s��rie de consequ��ncias negativas: a) A beleza �� ef��mera e os amantes abandonam; b) O decl��nio f��sico e mental �� inevit��vel; c) Na fase final da vida, sobrev��m o temor da morte. Para expressarem o efeito da senectude, Shakespeare e Eug��nio recorrem a compara����es semelhantes entre o ser humano e o Outono (velhice) e o Inverno (morte). Neste artigo, numa perspectiva comparada e intertextual, exemplifico e analiso essas melanc��licas e dolorosas imagens. Para tanto, recorro �� obra dos dois escritores, �� opini��o de ensa��stas reputados na ��rea dos estudos liter��rios e da psicologia da morte e, naturalmente, �� minha opini��o.

Hepatites p��s-transfusionais na cidade de Campinas, SP, Brasil: I. Incid��ncia, agentes etiol��gicos e aspectos cl��nico-epidemiol��gicos da hepatite por v��rus C

Seguimos ambulatorialmente, por no m��nimo 180 dias, 111 receptores de transfus��es, para avaliarmos a ocorr��ncia de hepatites p��s-transfusionais e os agentes etiol��gicos envolvidos com esta doen��a, na cidade de Campinas, Estado de S��o Paulo, Brasil. No final diagnosticamos esta hepatite em 18 (16,2%) receptores. Destes, tivemos 16 (89%) casos devido ao v��rus da hepatite C, 1 (5,5%) causado pelo v��rus da hepatite B e 1 (5,5%) caso restante, sem etiologia determinada, 15 meses ap��s a transfus��o. O per��odo de incuba����o da hepatite por v��rus C (HVC) foi de 71 dias, em m��dia; e 23% dos indiv��duos com esta hepatite permaneceram com aumento de AST/ALT por mais de 6 meses. Observou-se soroconvers��o tardia para o anti-HCV em 71,4% dos receptores, que ocorreu, em m��dia, 135 dias ap��s a transfus��o. Uma dosagem de ALT e uma pesquisa do anti-HCV, aos 3 e 6 meses, ap��s a transfus��o, diagnosticariam, respectivamente, 71 e 93% dos casos que desenvolveram HVC p��s-transfusionais.

Educa����o em sa��de em escolas p��blica de 1�� grau da periferia de Belo Horizonte, MG, Brasil: I - avalia����o de um programa relativo �� esquistossomose

O presente trabalho integra um amplo programa de pesquisa acerca da realidade educacional das escolas p��blicas de 1�� grau, visando desenvolver e avaliar alternativas criativas que estimulem a inclus��o da educa����o em sa��de sob enfoque transdisciplinar, utilizando recursos l��dicos como arte, literatura, jogos, teatro, etc. Este estudo foi realizado em 4 escolas municipais da periferia de Belo Horizonte com o objetivo de avaliar o impacto de um programa educativo em rela����o ao conhecimento e preval��ncia da esquistossomose. Os resultados demonstraram que, ap��s um ano de implanta����o dos novos materiais e metodologias, o conhecimento sobre a doen��a aumentou significativamente nas escolas experimentais, n��o se verificando o mesmo nas de controle. Em rela����o �� preval��ncia, observou-se uma queda geral de 12,9% para 9,0%, considerando as 4 escolas. Quando analisadas separadamente, a escola experimental de alta preval��ncia foi a que apresentou melhor resultado, registrando-se um decr��scimo significativo de 19,5% para 10,2%.

Surveillance of arbovirus infections in the atlantic forest region, State of S��o Paulo, Brazil: I. detection of hemagglutination-inhibition antibodies in wild birds between 1978 and 1990

We report data related to arbovirus antibodies detected in wild birds periodically captured from January 1978 to December 1990 in the counties of Sales��polis (Casa Grande Station), Itapetininga and Ribeira Valley, considering the different capture environments. Plasmas were examined using hemagglutination-inhibition (HI) tests. Only monotypic reactions were considered, except for two heterotypic reactions in which a significant difference in titer was observed for a determined virus of the same antigenic group. Among a total of 39,911 birds, 269 birds (0.7%) belonging to 66 species and 22 families were found to have a monotypic reaction for Eastern equine encephalitis (EEE), Venezuelan equine encephalitis (VEE), Western equine encephalitis (WEE), Ilheus (ILH), Rocio (ROC), St. Louis encephalitis (SLE), SP An 71686, or Caraparu (CAR) viruses. Analysis of the data provided information of epidemiologic interest with respect to these agents. Birds with positive serology were distributed among different habitats, with a predominance of unforested habitats. The greatest diversity of positive reactions was observed among species which concentrate in culture fields.

Chagas' disease in the Brazilian Amazon: I - a short review

At least eighteen species of triatominae have been found in the Brazilian Amazon, nine of them naturally infected with Trypanosoma cruzi or "cruzi-like" trypanosomes and associated with numerous wild reservoirs. Despite the small number of human cases of Chagas' disease described to date in the Brazilian Amazon the risk that the disease will become endemic in this area is increasing for the following reasons: a) uncontrolled deforestation and colonization altering the ecological balance between reservoir hosts and wild vectors; b) the adaptation of reservoir hosts of T.cruzi and wild vectors to peripheral and intradomiciliary areas, as the sole feeding alternative; c) migration of infected human population from endemic areas, accompanied by domestic reservoir hosts (dogs and cats) or accidentally carrying in their baggage vectors already adapted to the domestic habitat. In short, risks that Chagas' disease will become endemic to the Amazon appear to be linked to the transposition of the wild cycle to the domestic cycle in that area or to transfer of the domestic cycle from endemic areas to the Amazon.
