Ostracodos do Toarciano de Rabaçal (região de Coimbra): novos dados biostratigr...
Loureiro, I. M.; Cabral, M. C.; Duarte, L. V.; Azerêdo, A. C.Foram estudados os ostracodos de 58 amostras margosas representativas de toda a série toarciana do corte de Rabaçal. Esta série margo-calcária, depositada em meio marinho profundo, é rica em macrofauna nectónica e bentónica, estando bem calibrada biostratigraficamente por amonóides e nanofósseis calcários. Os novos resultados agora obtidos para os ostracodos permitem estabelecer uma escala biostratigráfica para...

Preliminary data on the ostracod fauna from the Lower Toarcian of Peniche
Pinto, S.; Cabral, M. C.; Duarte, L. V.Preliminary results of the systematic and biostratigraphical study of the ostracods from the Lower Toarcian (Polymorphum and Levisoni Zones) of Peniche are presented. Most of the identified species are recognized in other European countries. Biodiversity and species abundance are high in the first Zone, decreasing dramatically in the second one.
Hemagglutinating and fusogenic activities of Newcastle disease virus: studies o...
Couceiro,E. S. S.; Couceiro,J. N. S. S.; Cabral,M. C.Vaccinal and wild strains of Newcastle Disease virus (NDV) were analyzed for cell receptor binding and fusogenic biological properties associated with their HN (hemagglutinin-neuraminidase) and F (fusion protein) surface structures respectively. The evaluation of the biological activities of HN and F was carried out respectively by determination of hemagglutinating titers and hemolysis percentages, using erythr...
Comparative evaluation of a simple and sensitive assay for detection of orthomy...
Couceiro,J. N. S. S.; Couceiro,E. S. S.; Pinto,A. M. V.; Machado,R. D.; Cabral,M. C.Studies were done to evaluate comparatively the traditional HA assay and a more recently introduced lectin-neuraminidase (LN) methodologyin search of a simple and sensitive assay for virus detection during laboratorial diagnosis. The results proved the value of LN assay as a sensitive methodologyfor detection of virus particles, presenting results at least equal to those obtained by HA (hemagglutination) assay,...
