Structure, growth and production of a remarkably abundant population of the com...

The common goby, Pomatoschistus microps, is a relevant species from estuarine food webs, playing important roles as predator of polychaetes and crustaceans and as prey for larger fishes and crustaceans. The Minho estuary (NW Portugal) is a relatively wellpreserved and productive system. To assess the population structure and production of P. microps in this estuary, monthly samples were undertaken in three diff...

Acidúria 3-hidroxi-3-metilglutárica em Criança com Síndrome de Down

Os autores apresentam um caso clínico de acidúria 3-hidroxi-3-metilglutárica (3HMG) numa criança do sexo feminino, de 2 anos de idade, com síndrome de Down. Apresentava hipoglicemia não cetótica, acidose metabólica, encefalopatia e um perfil anormal de ácidos orgânicos urinários, característico de acidúria 3HMG.A demonstração da deficiência da enzima 3-hidroxi-3-metilglutaril-CoA liase (HMG-CoA liase) em cultur...

Saúde Sexual e Reprodutiva das Adolescentes - a Nossa Realidade

Overview and Aims: Several behavioral and biological factors can make adolescents particularly vulnerable to unwanted pregnancies and sexually transmitted diseases. The aim of this study was to evaluate sexual behavior and contraceptive use patterns of a population of adolescents. Study Design: Retrospective study. Population: 163 female adolescents attending an Adolescence Unit for the first time, during 2010....

Restrição do Crescimento Fetal - Casuística de 4 Anos

Overview and aims: Fetal growth restriction (FGR) affects 15% of pregnancies and is associated with both increased perinatal and neonatal morbidity and mortality and long-term effects in adult life. Our aim was to describe cases and outcomes of FGR from a tertiary perinatal care centre and identify the predictors of neonatal morbidity and mortality. Study design: retrospective cohort. Population: pregnancies wi...

A neural network based intelligent predictive sensor for cloudiness, solar radi...

Accurate measurements of global solar radiation and atmospheric temperature, as well as the availability of the predictions of their evolution over time, are important for different areas of applications, such as agriculture, renewable energy and energy management, or thermal comfort in buildings. For this reason, an intelligent, light-weight and portable sensor was developed, using artificial neural network m...

Synthesis and Biological Activity of 6-Selenocaffeine: Potential Modulator of C...

We report the development of a new microwave-based synthetic methodology mediated by Woollins’ reagent that allowed an efficient conversion of caffeine into 6-selenocaffeine. A preliminary evaluation on the modulation of antioxidant activity upon selenation of caffeine, using the DPPH assay, indicated a mild antioxidant activity for 6-selenocaffeine, contrasting with caffeine, that exhibited no antioxidant acti...

Ecological and morphological features of Amyloodinium ocellatum occurrences in ...

Understanding the patterns of occurrence of the ectoparasite Amyloodinium ocellatum and the conditions that result in its maintenance at non-dangerous levels for gilthead seabream Sparus aurata could be very useful, since outbreaks of heavy infestation by this parasitic dinoflagellate can cause severe mortality in temperate aquaculture. We have evaluated the interactions between A. ocellatum and related environ...

Characterization of molecular factors from plants pathogen Phytophthora cinnamomi

The culture of the chestnut tree is extremely important in the northern region of Portugal, occupying a significant proportion of useful agricultural area. The annual average chestnut production in Portugal can reach 20 000 tons. New plantation areas have increased in the last few decades. However the ink disease caused by the oomycete Phytophthora cinnamomi has damage and killed many trees and up to now no con...
