Nevertheless, the development of a colonic pseudotumor is a rare benign entity that can be easily misdiagnosed as a colonic neoplasm if the radiologist is not aware of this condition. We present a case of a 4...
Aluminum and Sulphate Removal by a Highly Al-Resistant Dissimilatory Sulphate-R...
Martins, M; Taborda, R; Silva, G; Assunção, A; Matos, AP; Costa, MCA highly Al-resistant dissimilatory sulphatereducing bacteria community was isolated from sludge of the wetland of Urgeiriça mine (community W). This community showed excellent sulphate removal at the presence of Al3+. After 27 days of incubation, 73,86 and 81% of sulphate was removed in the presence of 0.48, 0.90 and 1.30 mM of Al3+, respectively. Moreover,Al3+ was simultaneously removed: 55,85 and 78% of meta...
Genetic Characterization of an Insect-Specific Flavivirus Isolated from Culex T...
Parreira, R; Cookc, S; Lopes, A; Matos, AP; Almeida, AP; Piedade, J; Esteves, AWe describe the full genetic characterization of an insect-specific flavivirus (ISF) from Culex theileri (Theobald) mosquitoes collected in Portugal. This represents the first isolation and full characterization of an ISF from Portuguese mosquitoes. The virus, designated CTFV, for Culex theileri flavivirus, was isolated in the C6/36 Stegomyia albopicta (=Aedes albopictus) cell line, and failed to replicate in v...
