We present optical lightcurves and spectra of the afterglow of the gamma-ray burst (GRB) of February 18, 2006. GRB 060218 is a nearby long GRB which is clearly associated with a supernova – dubbed SN 2006aj. Our optical lightcurves define the rise times, the lightcurve shapes and the absolute magnitudes in the U , V and R bands, and we compare these data(More)
INTRODUCTION Distribution of HIV-1 subtypes is variable around the world, with the most common subtype in western Europe being subtype B. The aim our study was to describe the prevalence of different HIV-1 subtypes in newly diagnosed patients and identify demographic and epidemiological characteristics related with different subtypes.

INTRODUCTION Presence of viral mutations conferring resistance to antiretroviral drugs has potential impact on success of antiretroviral therapy (ART). The aim of this study was to describe the prevalence of resistance-associated mutations in HIV-infected patients without prior ART in a Portuguese cohort. MATERIALS AND METHODS Retrospective single-centre(More)
Aims. We have studied the afterglow of the gamma-ray burst (GRB) of February 18, 2006. This is a nearby long GRB, with a very low peak energy, and is therefore classified as an X-ray Flash (XRF). XRF 060218 is clearly associated with a supernova – dubbed SN 2006aj. Methods. We present early spectra for SN 2006aj as well as optical lightcurves reaching out(More)
