Group B Streptococcus Hijacks the Host Plasminogen System to Promote Brain Endo...
Magalhães, V.; Andrade, E.; Alves, J.; Ribeiro, A:; Kim, K.; Lima, M.; Trieu-Cuot, P.; Ferreira, P.Group B Streptococcus (GBS) is the leading cause of meningitis in neonates. We have previously shown that plasminogen, once recruited to the GBS cell surface and converted into plasmin by host-derived activators, leads to an enhancement of bacterial virulence. Here, we investigated whether plasmin(ogen) bound at the GBS surface contributes to blood-brain barrier penetration and invasion of the central nervous s...
Changes in paleotemperature and paleoproductivity over the last 40,000 years: N...
Martins, V.; Dias, J. M. A.; Moreno, J.; Salgueiro, E.; Mackensen, A.; Rubio, B.; Rey, D.; Magalhães, V.; Santos, J. F.; Rocha, F.; Laut, L.This work aims to identify changes in paleoceanographic conditions on the NW Iberian Continental Margin during the last ~40 ka BP. Paleotemperatures expressed as mean annual Sea Surface Temperature (SSTma) and paleoproductivities expressed as Export Productivity (Pexpma) were evaluated using the modern analog technique SIMMAX 28, based on planktonic foraminifera census counts. The study took into account the re...
Phenotyping and genotyping methods applied to investigate the relatedness of br...
Darini, A.L.C.; Magalhães, V.D.; Levy, C.L.; Barth, Afonso Luis; Coscina, A.L.In order to evaluate the resolving power of several typing methods to identify relatedness among Brazilian strains of Enterobacter cloacae, we selected twenty isolates from different patients on three wards of a University Hospital (Orthopedics, Nephrology, and Hematology). Traditional phenotyping methods applied to isolates included biotyping, antibiotic sensitivity, phage-typing, and O-serotyping. Plasmid pro...
Dyeability of corona-treated fabrics
Carneiro, Noémia; Souto, A. Pedro; Silva, Maria Elisabete; Marimba, A.; Tena, B.; Ferreira, Helena; Magalhães, V.In this study, corona technology is applied in the wet processing of cotton fabrics. The properties of cotton, such as hydrophilicity, ionisation and mechanical properties, are evaluated and compared with previous results of cuticle oxidation and morphological changes. The results of dyeings of coronatreated materials under different conditions are compared with those of raw, bleached and desized cotton. The dy...

Vibrio fluvialis attachs to but does not enter Hela cell monolayers
Carvalho,I. T.; Magalhães,V.; Leal,N. C.; Melo,V.; Magalhães,M.Considering the possibility that invasiveness could be a neglected factor of virulence in Vibrio fluvialis-linked enteritis, since a dysenteric form of the disease was seen in Bangladesh, we studied 12 Brazilian strains of the organism, six clinical and six environmental, to determine whether they might be able to enter into HeLa cell monolayers or would carry plasmids incidentally involved in invasiveness. Fou...
Severity evaluation of ventilated patients at a respiratory intensive care unit...
Brum, G; Serviço de Pneumologia, Hospital de Santa Maria, Faculdade de Medicina de Lisboa.; Teixeira, E; Barroso, C; Monteiro, F; Alves, S; Magalhães, VAPACHE II system, is a simple and inexpensive method to evaluate severity of Intensive Care Patients. In a 2 years period (between 1988 and 1990), grading severity using APACHE II system, was performed on 498 consecutive mechanical Ventilated Patients in a Respiratory Intensive Care Unit. APACHE II was higher in COPD patients, but patients with Pneumonia and Organophosphate Poisoning had higher mortality. Corre...
