Use of ß-glucanases and ß-1,4-xylanases to supplement diets containing alfalfa ...

It is well established that the use of alfalfa in diets for monogastric animals is limited by its high fiber content. However, alfalfa is a natural source of xanthophylls and gives poultry products a desirably yellow color. In addition, alfalfa saponins may contribute to reduce the levels of cholesterol in the meat and egg yolk. We have investigated the potential utilization of β-glucanases and β-1,4-xylanases ...

Carbon financial markets : a time-frequency analysis of CO2 price drivers

We characterize the interrelation of CO2 prices with energy prices (gas and electricity), and with economic activity. Previous studies have relied on time-domain techniques, such as Vector Auto-Regressions. In this study, we use multivariate wavelet analysis, which operates in the time-frequency domain. Wavelet analysis provides convenient tools to distinguish relations at particular frequencies and at particul...

Dor Abdominal Recorrente e Infecção por Helicobacter pylori: PRIMUM NON NOCCERE

A relação entre Dor Abdominal Recorrente (DAR) na criança e a infecção por Helicobacter pylori (Hp) tem sido longamente debatida, mantendo-se ainda um assunto polémico.No sentido de investigar este problema avaliaram-se 35 crianças com DAR da Consulta Externa de Gastroenterologia Pediátrica do Hospital de S. João.Métodos: Os doentes incluídos no estudo efectuaram investigação clínica e analítica adequada a cada...

Oil shocks and the euro as an optimum currency area

We use wavelet analysis to study the impact of the Euro adoption on the oil price macroeconomy relation in the Euroland. We uncover evidence that the oil-macroeconomy relation changed in the past decades. We show that after the Euro adoption some countries became more similar with respect to how their macroeconomies react to oil shocks. However, we also conclude that the adoption of the common currency did not ...

Laser assisted flow deposition: a new method to grow ZnO

Zinc oxide (ZnO) has been one of the most studied materials in the last decades. Either as bulk material, epilayers or nanostructures, this direct wide band gap semiconductor is known to possess great potential for fundamental science and modern technology applications.

A novel flow cytometric protocol for assessment of yeast cell adhesion

Microbial adhesion is a field of recognized relevance and, as such, an impressive array of tools has been developed to understand its molecular mechanisms and ultimately for its quantification. Some of the major limitations found within these methodologies concern the incubation time, the small number of cells analyzed, and the operator's subjectivity. To overcome these aspects, we have developed a quantitative...

Recomendações para Análise Mutacional em Tumores do Estroma Gastrointestinal (G...

Os autores apresentam as recomendações para a análise mutacional de GISTs, aprovadas por unanimidade por um grupo multidisciplinar em 20 de Julho de 2012. O estado mutacional de genes como o KIT e o PDGFRA permite identificar alvos terapêuticos para inibidores da tirosinacínase (ITKs) e, por isso, a boa prática clínica nas decisões bioterapêuticas de doentes com GISTs deve incluir a análise do estado mutacional...

Recommendations for Mutational Analysis in Gastrointestinal Stromal Tumors (GIS...

GIST Portuguese Working Group – Condeixa ProposalThe authors outline recommendations for the mutational analysis of GISTs unanimously approved by a multidisciplinary group on July 20th, 2062. The mutational status of KIT and PDGFRA allows identifying therapeutic targets to tyrosine kinase inhibitors (TKIs), and therefore, the safe clinical practice in the biotherapy decisions for patients with GISTs should incl...
