Complete blood count parameters as biomarkers of retinopathy of prematurity: a ...
Fevereiro-Martins, M; Santos, AC; Marques-Neves, C; Guimarães, H; Bicho, M; Afonso, C; Ferreira, J; Espírito Santo, R; Teixeira, F; Rosa, RPurpose: To evaluate complete blood count (CBC) parameters in the first week of life as predictive biomarkers for the development of retinopathy of prematurity (ROP). Methods: Multicenter, prospective, observational study of a cohort of preterm infants born with gestational age (GA) < 32 weeks or birth weight < 1500 g in eight Portuguese neonatal intensive care units. All demographic, clinical, and laboratory d...
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...

Spreading of HIV-1 subtype G and envB/gagG recombinant strains among injecting ...
Esteves, A; Parreira, R; Piedade, J; Venenno, T; Franco, M; Sousa, JG; Patrício, L; Brum, P; Costa, A; Canas-Ferreira, WWe have evaluated the genetic diversity of HIV-1 strains infecting injecting drug users (IDUs) in Lisbon, Portugal. Heteroduplex mobility assay and/or phylogenetic analysis revealed that env (C2V3C3 or gp41) subtype B is present in 63.7% of the 135 viral samples studied, followed by subtypes G (23.7%), A (6.7%), F (5.2%), and D (0.7%). Similar analysis of gag (p24/p7) performed on 91 of the specimens demonstrat...
Molecular epidemiology of HIV type 1 infection in Portugal: high prevalence of ...
Esteves, A; Parreira, R; Venenno, T; Franco, M; Piedade, J; Sousa, JG; Canas-Ferreira, WIn this study, we have investigated the diversity of current HIV-1 strains circulating in the metropolitan area of Lisbon, Portugal. A total of 217 HIV-1-positive blood samples, collected between October 1998 and December 2000, was genetically characterized in the gp120 C2V3C3 region (n = 205) or part of the gp41 N-terminal segment (n = 12) by heteroduplex mobility assay (HMA) and/or DNA sequencing. The HMA sub...
