Evaluation of enniatins A, A1, B, B1 and beauvericin in Portuguese cereal-based foods.

2012

Sixty-one samples of Portuguese cereal-based foods were analysed for the occurrence of emerging mycotoxins called enniatins (A, A1, B and B1) and beauvericin. Samples were extracted with a mixture of acetonitrile/water (85/15, v/v) using an Ultra-Turrax homogeniser, and mycotoxins were detected with liquid chromatography coupled to a mass spectrometer. This method was validated and adequate values of recovery (70-103%) and relative standard deviation (15%) were obtained. Signal suppression/enhancement was studied and matrix-matched calibration used to minimise this effect, but no additional clean-up step was necessary. The mass spectrometer was operated in selected reaction monitoring (SRM)…

Between conflicts and commerce: The impact of institutions and wars on Swedish-Portuguese Trade, 1686-1815

2015

This paper is related to a multiyear project aimed at compiling new data on the early modern trade flows between smaller (or weaker) states. It presents a quantitative analysis of the nature and volume of trade between Sweden and Portugal during the period in question, seeking to identify long-run changes in these flows and to determine whether institutional changes and wars fundamentally altered the composition, trends, or volume of trade. First, it appears that trade between Portugal and Sweden hinged on only a few key commodities, most importantly iron from Sweden and salt from Portugal. In particular, we found that Portugal was somewhat more dependent on Swedish iron than Sweden was on …

Los datos muestran que los turistas son, en su mayoría, mujeres, con edad media de 69.43 años (dp=5.28), casadas, que viven en la región norte de Portugal; y tienen como principal nivel de educación la enseñanza secundaria. La principal motivación para participar en el programa de turismo es el interés en las actividad…

Epidemiology of tattoo skin disease in bottlenose dolphins Tursiops truncatus from the Sado estuary, Portugal

2003

We report on the epidemiology of tattoo disease in a community of bottlenose dolphins Tursiops truncatus from the Sado estuary, Portugal. The presence of tattoos (T++) and tattoo-like (T+) lesions was examined in 586 photographic records of 35 dolphins taken from 1994 to 1997. Images were rated into 3 categories: good (GI), average (AI) and poor (PI). Dolphins positive for T++ lesions were observed in 19 GI. Dolphins with T+ lesions were seen in 39 GI, 23 AI and 6 PI. For statistical analysis the dolphins were divided into 2 age classes (immature and adult) and the data grouped into 2 periods (1994-1995 and 1996-1997). Minimum prevalence of T++ lesions in 32 dolphins was 21.9% in 1994-1995 …

Curricula for the teaching of complete dentures in Spanish and Portuguese dental schools

2012

Objectives: Given the need to ensure that dentists are sufficiently skilled to offer the best possible care to their patients, this study aims to evaluate the teaching methods and clinical experience achieved by undergraduate dental students in Spain and Portugal as regards complete dentures. Study design: In February 2011, a questionnaire seeking information about the preclinical and clinical teaching of complete dentures was e-mailed to all Spanish and Portuguese dental schools with fully developed undergraduate degree dental programs. Results: A response rate of 82.6% was obtained. The distribution of lectures and hours spent at the laboratory and in clinical activities revealed that tea…

Droghe leggere e criminalità organizzata: una relazione problematica

2022

Il contributo analizza il tema dei rapporti tra trattamento penale delle droghe c.d. “leggere” e contrasto alla criminalità organizzata dedita al narcotraffico, con riguardo all’ordinamento europeo, internazionale e di alcuni Paesi dell’UE (Spagna, Portogallo, Grecia, Germania e Italia). Seguendo un approccio di tipo integrato, all’analisi del dato normativo si affianca la descrizione della fenomenologia dei traffici e la valutazione dei primi effetti che le riforme antiproibizioniste entrate in vigore in alcuni ordinamenti del Nord e del Sud America hanno prodotto sul fronte del mercato illecito. Il fine è di evidenziare i punti di forza e di debolezza dei modelli di depenalizzazione, tene…

Occurrence of fumonisins B1 and B2 in broa, typical Portuguese maize bread

2007

Fumonisin B1 (FB1) and fumonisin B2 (FB2) are mycotoxins mainly produced by Fusarium verticillioides, and Fusarium proliferatum, fungi species most commonly isolated from maize. The natural occurrence of FB1 and FB2 in broa, typical Portuguese maize bread, was evaluated in 30 samples. Twenty five were found positive with levels ranging from 142 to 550 [mu]g kg- 1. The limit established by the European regulations was exceeded by 27% of the samples. The tolerable daily intake for fumonisin B1, and B2, alone or in combination, for all of the analysed samples, was lower than 2 [mu]g kg- 1 body weight per day established by the European Commission. http://www.sciencedirect.com/science/article/B…
