Les ostracodes du Miocène inférieur de la region de Lisbonne (basin du Tage)

Forty-five species of ostracoda from the Aquitanian of the Lisbon area, belonging in thirty-two genera, are presented. These are the first species belonging to this group reported for the Miocene formations in Portugal. Ostracoda assemblages are typical of fresh water, brackish and marine environments (littoral and inner continental shelf). References are made to the stratigraphically more significant species. Data on the paleoenvironments are also presented. A list of the studied species includes a comparison with their distribution in the Aquitaine and Rhone Miocene basins.

Particularités de la microfaune (Foraminifère) à la limite Carixien/Domérien de quelques gisements de la region de Coimbra (Portugal)

The Middle Liassic outcrops of the Coimbra region (Portugal) show, at Carixian-Domerian boundary, an unusual high frequence of the Falsopalmula, morphogenus,that is generally well represented in the Lower Toarcian. The study of the Nodosaridea association shows that the massive presence of this morphogenus excludes the Lenticulina s. st. genus. These faunistic particularities should be ascribed to the environment and to the sedimentation pattern. The development of the Falsopalmula morphogenus should have been simultaneous to that of the pelitic sedimentation.

Le gisement de Asseiceira, Portugal (Miocène supérieur) Données complémentaires sur Freiria de Rio Maior

A new upper Miocene locality at Asseiceira (Rio Maior), near the top of the "Calcários de Almoster e Santarém" unit (Almoster and Santarém limestones) is studied. Animal and plant fossils are described. Comparisons are drawn to other localities related to the same unit: Freiria and Azambujeira (middle and upper levels, both with large mammals). Small mammals from Asseiceira and Freiria point out to a rather old age amidst the upper Vallesian, MN 10 mammal-unit. This gives a fairly accurate datation for the "Calcários de Almoster e Santarém" and for the short time span of the corresponding sedimentation. Climate was warm and quite dry, with contrasting seasons and arid events. During upper Vallesian times, climate in Iberian Peninsula was varied but drier than in France, and specially so in the inner basins. However in Portugal and in Catalonia climate would he less different in comparison with that of the Rhône basin. Environmental evolution has been important: at Freiria and Azambujeira (middle level) there were mainly shallow lacustrine environments that received ressurgence waters from the nearby "Maciço calcário". Humid areas were closely surrounded by dense forests and these by broader and drier savanna or steppe areas. Still later, carbonate sedimentation ended. For some time there was still a river system with oxbows; humid areas probably were decreasing in favour of surrounding, rather dry environments. This study stressed the nced for revision of the geology of the region of Rio Maior and for a new geological mapping of that area. Environmental evolution has been important: at Freiria and Azambujeira (middle level) there were mainly shallow lacustrine environments that received ressurgence waters from the nearby "Maciço calcário".

Desenvolvimento de um ensaio de hibridação múltipla (MHA-MULTIPLE REGION HYBRIDIZATION ASSAY) para identificação presumível de vírus da imunodeficiência humana do tipo 1 (HIV-1) dos subtipos B, G e de formas recombinantes CRF14_BG e CRF02_AG circulantes em Portugal

A maioria dos métodos utilizados na caracterização genética do HIV-1 baseia-se na análise de regiões específicas do genoma viral, fornecendo informação parcial sobre o mesmo e, por consequência, revelando-se inadequados para a identificação de vírus recombinantes. O único método que permite uma caracterização integral do genoma viral passa pela sua sequenciação completa. No entanto, este é um método dispendioso, laborioso e de difícil implementação quando se pretende a análise de elevados números de amostras. Como alternativa a este último, o conjunto de métodos genericamente designados de MHA (Multiple Region Hybridization Assay) baseiam-se na amplificação, por PCR em tempo-real, de várias regiões ao longo do genoma viral e na sua caracterização com sondas específicas (TaqMan). Tendo este modelo por base, o objectivo deste estudo foi o desenvolvimento de um ensaio de hibridação múltipla (MHABG0214) passível de ser aplicado ao estudo de um elevado número de amostras. Este método foi desenvolvido tendo como objectivo a genotipagem as estirpes circulantes dominantes na epidemia Portuguesa, nomeadamente os subtipos B, G e formas genéticas recombinantes CRF02_AG e CRF14_BG. Com base em alinhamentos de sequências de referência de genoma completo, delinearam-se primers universais e subtipo-específicos para a amplificação de diversas regiões codificantes distribuídas ao longo do genoma do HIV-1 (Gag, Protease, Transcriptase Reversa, Integrase, Rev, Gp120 e Gp41). A optimização foi efectuada, inicialmente, para um conjunto de amostras de referência e seguidamente avaliada num conjunto de 50 amostras clínicas. O MHABG0214 foi implementado numa estratégia de PCR em tempo-real, numa detecção dependente de SYBR® Green I para todas as regiões ou, como alternativa, usando sondas TaqMan (Gp41). Apresentamos ainda uma estratégia em que a análise de resultados se baseia, simplesmente, numa abordagem usando PCR/gel de agarose convencional. Estas abordagens constituem ferramentas úteis na identificação das estirpes de HIV-1 em Portugal.
