Levels of ochratoxin A in wheat and maize bread from the central zone of Portugal.

2007

Ochratoxigenic fungi are natural contaminants of cereal and the produced toxins are harmful to humans and animals. Ochratoxin A (OTA) is among the most important mycotoxins, and the International Agency for Research on Cancer (IARC) classifies it as possibly carcinogenic to humans (group 2B). A total of 61 samples of bread from the central zone of Portugal were analysed for OTA by liquid chromatography (LC) with fluorescence detection (FD). For confirmation two procedures were applied, methyl ester derivatization with boron trifluoride-methanol and liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI/MS/MS). As far as we know, this is the first report where on-line…

Miocene lithological, foraminiferal and palynological data from the Belverde borehole (Portugal)

2021

XVIII Jornadas de Paleontología, 2002 Preliminary data on litho stratigraphy and biostratigraphy of the Belverde borehole (http://www. dct.Jct.unl.pt/ SondagemISondagem/colunalindex_col.html) is presented. The borehole attained 619,77 m of depth, crossing 130 m of Plio-Pleistocene and 460 m of Miocene dep osits. Main lithologies are fine sands , marl s and biocalcarenites. A coral reef was recognized in the lower part of the borehole (530-585 m). Gamma ray, neutrons and sonic diagraphies were obtained. Eight 87Sr/86Sr isotopic ages (H. Elderfield, Cambridge University)and the presence of some of the main planktonic foraminifera markers were used to establish the chronostratigraphic framewor…

Oral soft tissue biopsies in Oporto, Portugal: An eight year retrospective analysis

2015

Background: The diseases that affect the oral cavity are wide and diverse, comprising a broad spectrum of either benign or malignant lesions. However, few histological-based studies were performed for the evaluation of oral cavity lesions, and very few directed to oral soft tissue pathology. The aim of this study was to carry out pioneering research, within a Portuguese population, to determine the frequency and characteristics of oral malignancies, po - tential malignant disorders, and soft benign tissues pathologies submitted for biopsy in a north Portugal (Oporto) hospital population. Material and Methods: We performed a retrospective study of soft tissue, oral cavity biopsies, in a hosp…

International student mobility in Southern-Latin Europe: beyond the EU logics, towards a new space

2018

This paper discusses international student mobility (ISM) in Southern-Latin Europe, specifically Italy, Portugal, and Spain, analysing the inflow of international students as reflected in the UNESCO, OECD and European Commission databases. Only recently Italy, Portugal and Spain, as latecomers, have become more actively involved in ISM dynamics. This trend has been a response to EU pressures to internationalization, instrumented through the consolidation of the Bologna process and the need to build a common space of higher education. The analysis shows that at the intra-European level Italy, Portugal and Spain share similar ISM patterns; however, in the global context other logics shape ISM…

Estado de bienestar bajo ataque: consecuencias esperadas y disimuladas de la Troika

2016

El presente artículo, partiendo de la especificidad del modelo de salud portugués y del papel que juega el Estado para enfrentar la crisis económica, analiza cómo las políticas de austeridad que tuvieron lugar durante la troika en Portugal afectaron la sociedad, especialmente los inmigrantes, condicionándoles el acceso a los servicios de salud. El Estado de Bienestar sale debilitado, y pone en evidencia que la acción de la sociedad de bienestar (Santos 1992 y 1995) y de la «safety net» (Ferrera, 2005) adquieren una gran importancia, compensando las deficiencias estatales. En consecuencia, la sociedad de bienestar asume roles de colaboración, mediación e intervención como estrategias relacio…

The Sinemurian ammonites of the Lusitanian Basin (Portugal): an example of complex endemic evolution.

2010

29 pages; International audience; This work synthesizes all of the observations since the late nineteenth century of the highly endemic Late Sinemurian (Obtusum Chronozone) ammonite faunas of the Lusitanian Basin. It is based mainly on recent abundant collections from the Penedo da Saudade section near São Pedro de Muel (Leiria, Portugal). This rich material (some eight species and four genera), collected bed by bed, allows us to propose an initial biostratigraphic, palaeobiogeographic, evolutionary and taxonomic synthesis of these mostly endemic faunas. The genus Epophioceroides n. gen. is new and three new species are identifi ed: Epophioceroides apertus n. gen. n. sp., Ptycharietites (Su…
