An observational retrospective study of odontogenic cyst´s and tumours over an 18-year period in a Portuguese population according to the new WHO Hea…

2020

Background Odontogenic cysts and tumours of the jaws represent one of the most prevalent groups of oral-maxillofacial lesions. We aimed to evaluate the clinical and pathological characteristics of a cohort of odontogenic cysts (OC) and odontogenic tumours (OT) of the jaws in a Portuguese population. Material and Methods This observational retrospective study analysed patients diagnosed with either an OC or OT of the jaws at a central hospital of Oporto, Portugal, between 1988 and 2006. Data collected from patients’ files included demographic, clinical, radiological and histopathological information. Recurrence was evaluated using univariate and multivariate analysis. Results The sample cons…

A clinical-pathological and survival study of oral squamous cell carcinomas from a population of the North of Portugal

2014

Objectives: Our aim was to analyze the clinical, pathological, and outcome characteristics of oral squamous cell carcinomas (OSCC) from a population of the north of Portugal. Material and Methods: We conducted a descriptive study of 128 OSCC diagnosed between the years of 2000 and 2010 in the Centro Hospitalar do Porto. Through of the review of the clinical records we studied several clinical, pathological, and outcome variables. The overall survival (OS) and disease-free survival (DFS) were analyzed by Kaplan-Meier method and log-rank test. Cox regression method was used for multivariate analysis. Results: Of 128 patients with OSCC, 83 (64.8%) were male and 45 (35.2%) were female, (mean ag…

Pottery Production at the Beginning of the Neolithic in Portugal: Recent Data on the 6th and 5th Millennia BC

2019

A characterisation of the earliest pottery productions in Neolithic Portugal (6th millennium BC) was published in the pages of this journal a few years ago. However, three aspects have been receiving further attention by current research and are discussed here: 1) the relation between Cardial and Boquique-decorated potteries, in which the former are clearly more ancient i f a critical evaluation of the available chrono-stratigraphic evidence is carried out; 2) new finds of so-called "symbolic pottery", which includes abundant evidence for anthropomorphic and zoomorphic depictions along with more scarce examples of plant and solar representations; and 3) petrographic and chemical analyses of…

Phylogeography and genetic divergence of some lymnaeid snails, intermediate hosts of human and animal fascioliasis with special reference to lymnaeid…

1997

Abstract A population genetic study using starch gel electrophoresis was performed on populations of several species of lymnaeid snails acting as intermediate hosts for Fasciola hepatica (Trematoda, Plathyhelminth). Lymnaea viatrix was collected in 16 sites from the Bolivian Northern Altiplano. L. cubensis were obtained in one site from Venezuela, one site from Guadeloupe, three sites from Cuba and one site from the Dominican Republic. L. truncatula were collected in one site from France, one from Portugal and one from Morocco. Multilocus enzyme electrophoresis (MEE) were determined for 282 snails at 18 loci. A complete monomorphism was encountered at each geographic site. However, among th…

Sourcing african ivory in chalcolithic Portugal

2009

A recent review of all ivory from excavations in Chalcolithic and Beaker period Iberia shows a marked coastal distribution – which strongly suggests that the material is being brought in by sea. Using microscopy and spectroscopy, the authors were able to distinguish ivories from extinct Pleistocene elephants, Asian elephants and, mostly, from African elephants of the savannah type. This all speaks of a lively ocean trade in the first half of the third millennium BC, between the Iberian Peninsula and the north-west of Africa and perhaps deeper still into the continent.

Determination of organochlorine pesticide residues in honey from the central zone of Portugal and the Valencian community of Spain

2004

In this study nine organochlorine pesticide residues ([alpha]-, [beta]-, and [gamma]-hexachlorocyclohexane (HCH), hexachlorobenzene (HCB), aldrin, p,p'-DDE, p,p'-DDD, o,p'-DDT, and p,p'-DDT) in forty nine samples of honey collected from markets of Portugal and Spain during 2001 and 2002, respectively, were evaluated. For this evaluation, three analytical procedures were studied. The analytical procedure, based on LLE extraction with ethyl acetate followed by gas chromatography-electron-capture detection (GC-ECD) for quantification, and mass spectrometry (GC-MS) for confirmation, has been selected. Recoveries of spiked samples ranged from 68%, for [beta]-HCH, and 126% for p,p'-DDT, for forti…

Collaborative Governance in Portugal – Yes or No? A critical approach based on an empirical survey

2019

Collaborative governance can be defined as a concerted type of decision-making and collective action in which government bodies and private sector stakeholders interact as equal partners with the aim of achieving outcomes of interest for both parties. In practical terms, this is a type of governance where special meetings and negotiations are held – typically in somewhat elitist and secretive settings – with the aim of defining shared responsibilities and benefits associated with joint public-private ventures. Academic authors in favour of the adoption of collaborative governance in Portugal tend to present a rather positive view on the merits of this approach. They argue that it is potenti…

¿Proveer justicia u oprimir a los pueblos? La acción de los corregedores de las Azores en el periodo moderno

2020

En Portugal, los corregedores han sido presentados por la historiografía tradicional como uno de los pilares del proceso de centralización política que había tenido lugar en el reino portugués a partir del final de la Edad Media. Esta interpretación ha sido corregida en las últimas décadas por nuevas investigaciones e interpretaciones. En los territorios portu- gueses de ultramar, la distancia amplió algunos de los “obstáculos fácticos” (según Antonio Manuel Hespanha) que hacían difícil, si no imposible, la concreción de cualquier proyecto centralizador. El caso azoriano es de esto un buen ejemplo. En este artículo, además de una síntesis de los poderes de los corregedores…

The finger of Beelzebub. The consecration of judicial review of constitutionality in Portugal in 1911

2022

Without entirely breaking with the political review of constitutionality established in the 19th century, Portugal, which became a republic after the October 1910 revolution, decided to enshrine judicial review of constitutionality in its 1911 Constitution. The choice of the American model of diffuse review was intended to break with the main guarantee offered in the days of 'granted constitutionalism', when the moderating power of the King acted as guarantor of the Constitution alongside the political chambers. This was the aim of the promoter of this legal revolution, the law professor Afonso Costa, a strong man of the First Republic, who was able to convert his initially hostile republic…
