Methionine Adenosyltransferase I/III Deficiency in Portugal: High Frequency of ...

Methionine adenosyltransferase deficienc(MAT I/III deficiency) is an inborn error of metabolism resulting in isolated hypermethioninemia, and usually inherited as an autosomal recessive trait, although a dominant form has been reported in several families. During the last 6 years, approximately 520,000 newborns were screened in the Portuguese Newborn Screening Laboratory by MS/MS, and 21 cases of persistent hyp...

Moderate exercise training provides left ventricular tolerance to acute pressur...

The present study evaluated the impact of moderate exercise training on the cardiac tolerance to acute pressure overload. Male Wistar rats were randomly submitted to exercise training or sedentary lifestyle for 14 wk. At the end of this period, the animals were anaesthetized, mechanically ventilated, and submitted to hemodynamic evaluation with biventricular tip pressure manometers. Acute pressure overload was ...

Toxicity assessment of eight azo-dyes using Tetrahymena pyriformis

Establishing criteria for evaluating the portuguese geological heritage

The present work aims to test methodological approaches in the evaluation of the geological heritage. Procedures normally used in the assessment of biological values will be adapted for geosites evaluation. The Sintra-Cascais Natural Park, a protected area located in the Lisbon region, will be used as a case study.

Investigação Bioquímica e Molecular na Morte Súbita do Lactente (SIDS)

RESUMO SIDS (Sudden Infant Death Syndrome) é a designação utilizada para definir a morte súbita do lactente, que permanece inexplicada após uma cuidadosa investigação do caso, a qual incluí a realização de autópsia, o exame do local da morte e a análise da história clínica. Devido à rápida deterioração que provocam, as doenças metabólicas constituem potenciais causas de morte súbita, quer pelas crises que ocasi...

Avaliação do método de triagem para análise de milho contaminado com aflatoxina...

A técnica da fluorescência amarelo-esverdeada brilhante (BGYF) como método de triagem na avaliação de milho eventualmente contaminado com aflatoxina, utilizada por uma indústria alimentícia do Estado de São Paulo em 61 amostras de milho, foi comparada com a técnica BGYF padronizada, aplicada em laboratório antes e após trituração dos grãos e, também, com a técnica da cromatografia em camada delgada (CCD). Os re...

Post-harvest control of aflatoxin production in in-shell moist peanuts with sod...

The present experiment aimed to evaluate the effect of sodium ortho-phenylphenate (SOP) application to in-shell moist peanuts for the control of aflatoxin production. Previous studies showed the need to improve the SOP solution distribution on peanut pods to evaluate the product. Thus, in this experiment the place of the spray system was the bag filler pipe of the pre-cleaning machine in the warehouse. In the 1...

Aflatoxin removal of peanut meals with aqueous ethanol

A preliminary approach to achieve compatible simultaneous extraction of aflatoxin and residual oil from pressed oil meals was conducted to determine the minimum amount of water to be added to ethanol versus necessary time to achieve complete removal of aflatoxin. Commercial anhydrous, 96, 93 and 90°GL ethanol were utilized in trials with Soxhlet extractors. Commercial anhydrous ethanol did not remove aflato...
