Spatial distribution of acid mine drainage indexes in different water reservoirs

The Iberian Pyrite Belt (IPB) is one of the largest metallogenic province in the world, with more than 90 polymetallic massive sulphide deposits associated with the volcano-sedimentary complex of the Iberian Peninsula. The geological and mineralogical characteristics of this region have a reflection on the existence of Acidic Mine Drainage (AMD) producing wastes dispersed by the numerous mining complexes and di...

Cross-protection to new drifted influenza A(H3) viruses and prevalence of prote...

Introduction: Immune profile for influenza viruses is highly changeable over time. Serological studies can assess the prevalence of influenza, estimate the risk of infection, highlight asymptomatic infection rate and can also provide data on vaccine coverage. The aims of the study were to evaluate pre-existing cross-protection against influenza A(H3) drift viruses and to assess influenza immunity in the Portugu...

Influenza seroprotection correlates with predominant circulating viruses during...

BACKGROUND: Population immune profile for influenza is highly affected by circulating influenza viruses, thus changing the risk of infection for influenza. This study aims to assess influenza immunity in the Portuguese population by age groups, during 2014 and 2015 and establish a relationship between seroprotection and circulating influenza viruses in 2014/15 and 2015/16 seasons. METHODS: Two cross-sectional s...

Influenza severe cases in hospitals, between 2014 and 2016 in Portugal

Background: Since 2009, the Portuguese Laboratory Network (PLNID) for Influenza Diagnosis has integrated 15 Laboratories in mainland and Atlantic Islands of Azores and Madeira. This PLNID added an important contribute to the National Influenza Surveillance Program regarding severe and hospitalized influenza cases. The present study aims to describe influenza viruses detected in influenza like illness (ILI) case...

Rede Portuguesa de Laboratórios para o Diagnóstico da Gripe: inverno 2013/2014

A Rede Portuguesa de Laboratórios para o Diagnóstico da Gripe (RPLDG) integra, atualmente, 15 laboratórios maioritariamente hospitalares e é coordenada pelo Laboratório Nacional de Referência para o Vírus da Gripe (LNRVG) do Departamento de Doenças Infecciosas do Instituto Nacional de Saúde Doutor Ricardo Jorge, I.P. A RPLDG realiza o diagnóstico laboratorial do vírus da gripe assim como de outros vírus respira...

Severe acute respiratory infections in the 2012/2013 season studied by the Port...

During the 2009/10 influenza pandemic, a network of 14 laboratories located in the main reference hospitals from Portugal mainland, Madeira and Azores was established for the diagnosis of the new influenza A(H1N1)2009 pandemic strain. Since then, the network performs laboratory diagnosis of influenza as well as other respiratory pathogens, thus contributing to the laboratory diagnosis of respiratory disease in ...

Antibiofilm properties of quercus ilex acorn extracts against MRSA and MSSA

Biofilms are complex structures that grant microorganisms some survival advantages namely nutrient availability and antimicrobial resistance. As such, the need to find new antimicrobial compounds that are active against these structures is in great demand. Phenolic compounds are described as capable of interfering with the cellular membrane and interact with both intracellular and extracellular proteins, thus t...

Bioavailability of phenolic compounds from blueberry leaf infusions (Vaccinium ...

Phenolic compounds are widespread in plant-derived foodstuffs and therefore abundant in our diet. There are evidences regarding the positive association of their intake with several diseases prevention. Blueberry leaves are of particular interest as they have been described as being rich in phenolic compounds such as chlorogenic acid and quercetin glicosides. Bioavailability is a major issue regarding the biolo...
