The “Montado ecosystem” is important both economically and ecologically; this ecosystem is dominated by cork and holm oak trees (Quercus suber L. and Quercus rotundifolia Lam. respectively) combined with a rotation of crops/fallow/pastures. Diverse management strategies, deviating from the sustainable use of the ecosystem, have been implemented, from which arise some extreme situations of over-use or abandonmen...
INTRODUÇÃO: A população idosa que recorre ao Serviço de Urgência tem vindo a aumentar. É uma população com características fisiopatológicas específicas que coloca dilemas sobre o risco/benefício da cirurgia urgente. OBJECTIVOS: Comparar os scores P-POSSUM, CR-POSSUM e ACPGBI enquanto modelos de morbimortalidade cirúrgica nos idosos e muito idosos submetidos a cirurgia coloretal urgente por doença maligna. MAT...
Introdução: Os suportes vasculares restaurativos transitórios (sVRT) foram recentemente aprovados para intervenção coronária percutânea (ICP) na Europa e possuem propriedades muito inovadoras. O objetivo desta declaração de posição é rever criticamente a informação e os estudos com os sVRT disponíveis e contribuir para uma reflexão científica que promova o seu uso racional com orientações estruturadas para a su...
Although Staphylococcus aureus is a major cause of outbreaks in neonatal intensive care units (NICUs), there are no studies on the epidemiology of S. aureus isolates responsible for infection in Portuguese NICUs. Between July 2005 and December 2007, a total of 54 methicillin susceptible S. aureus (MSSA) isolates were recovered from 16 infected infants, parents, health care workers (HCWs), and the environment in...
As a component of aerosol, pollen is found in suspension with other mineralogical and anthropogenic particles that can adhere to the pollen wall. The aim of this study was to determine possible alterations that pollen grains suffer under different meteorological conditions in the coastal city of Porto, Portugal. For this study, 2 airborne pollen types were taken into account: Poaceae and Alnus spp sampled in ...
Background: Although the gene expression profile of several tissues in humans and in rodent animal models has been explored, analysis of the complete choroid plexus (CP) transcriptome is still lacking. A better characterization of the CP transcriptome can provide key insights into its functions as one of the barriers that separate the brain from the periphery and in the production of cerebrospinal fluid. Method...
A synthesis about the Neogene and Quaternary of Algarve (Southern Portugal) is presented. New isotopic 87Sr/86Sr ages as well as biostratigraphic data about the Miocene deposits allow to present a new stratigraphic frame for the previously characterized units. The Lagos-Portimão Formation corresponds to deposits of temperate carbonate platform sedimentological type, developed during a long time span (Lower Burd...
