In situ enzyme immunoassay for titration of a Brazilian hepatitis A virus strai...
Villar,L.M.; Amado,L.A.; Gaspar,A.M.C.Hepatitis A virus (HAV) replicates relatively slowly in cell culture without a cytopathic effect, a fact that limits the use of tissue culture assays. The radioimmunofocus assay is the standard method for HAV titration, although it is labor intensive and requires the use of radioisotopes. A simple, rapid and objective infectivity assay based on an in situ enzyme immunoassay (EIA) is described here for a Brazili...

Ventura, A; Ribeiro, J; Murinello, A; Amado, L; Morgado, A; Guerra, C; Murinello, F; Silva, JL; Mota, JAA neurofibromatose é uma doença que pode afectar todos os órgãos. As suas manifestações clínicas podem ser muito variáveis e associam-se-lhe, frequentemente, neoplasias. é o caso do feocromositoma, que na sua forma benigna, coexiste em 10 % dos casos; contudo, a descrição da associação com a forma maligna é uma raridade, o que justifica o interesse da divulgação da nossa experiência. Salientamos, no entanto, qu...

Ventura, A; Ribeiro, J; Murinello, A; Amado, L; Morgado, A; Guerra, C; Murinello, F; Silva, J L; Mota, J ANeurofibromatosis may involve every organ. Manifestations vary greatly and different kind of neoplasia may be associated with excessive frequency; it's the case of pheochromocytoma that, as a benign tumor, coexists in 10%. Description of coexistency as a malignant tumor is a rarity; therefore, we think it's interesting to publish our experience. Nevertheless the association of Von Recklinghausen's disease with ...
