Routine screening of harmful microorganisms in beach sands: implications to pub...

Beaches worldwide provide recreational opportunities to hundreds of millions of people and serve as important components of coastal economies. Beach water is often monitored for microbiological quality to detect the presence of indicators of human sewage contamination so as to prevent public health outbreaks associated with water contact. However, growing evidence suggests that beach sand can harbor microbes ha...

Síndromes de Falência Medular Hereditários — Seis Casos Clínicos

Os Síndromes de Falência Medular Hereditários são um grupo heterogéneo de doenças, que se caracterizam pela produção reduzida de uma ou mais linhagens hematopoiéticas pela medula óssea e consequentes citopenias no sangue periférico. Associam-se a um variado número de malformações congénitas e a maioria são entidades «pré-malignas».A propósito de seis casos, os autores tecem algumas considerações sobre as caract...

Human Papillomavirus Type Distribution in Cervical Intraepithelial Neoplasia Gr...

OBJECTIVE: Cervical cancer is the third most frequent cancer in women, worldwide and etiologically associated with infection by human papillomavirus (HPV). Following the results of the first epidemiologic population-based CLEOPATRE study in Portugal, it was important to understand the HPV type-specific distribution in women with cervical intraepithelial neoplasia (CIN) grades 2 and 3 and invasive cervical cance...

Earthquake Mitigation in the Lisbon and Lower Tagus Valley area, Portugal

The capital city of Lisbon and the Lower Tagus Valley region of central Portugal mainland are located in the Eurasian plate about 350 Km from the approximately E-W oriented Eurasia-Africa plate boundary. It is characterized by low slip-rates (<0.4 mm/year) and a moderate seismicity, occasionally shaken by some important historical earthquakes causing significant damages and economical losses. The most well know...

Dimethylaminopyridine derivatives of lupane triterpenoids cause mitochondrial d...

Triterpenoids are a large class of naturally occurring compounds, and some potentially interesting as anticancer agents have been found to target mitochondria. The objective of the present work was to investigate the mechanisms of mitochondrial toxicity induced by novel dimethylaminopyridine (DMAP) derivatives of pentacyclic triterpenes, which were previously shown to inhibit the growth of melanoma cells in vit...

Water content control to improve space charge storage in a cork derivative

The influence of humidity content on the electrical and dielectric properties of a composite made from recycled TetraPak® containers and granulated cork was studied. The material components have been dried before preparation and after the composite was conditioned by keeping the samples in a dry environment (desiccator) or in an oven at high temperature (70oC in air). The differences observed in electrical prop...
