Rapid light carbon releases and increased aridity linked to Karoo–Ferrar magmat...

Large-scale release of isotopically light carbon is responsible for the carbon isotope excursion (CIE) of the Toarcian Oceanic Anoxic Event during the Lower Jurassic. Proposed sources include methane hydrate dissociation, volcanogenic outgassing of carbon dioxide and/or thermogenic methane release from the Karoo‐Ferrar magmatic province (southern Africa). Distinct small-scale shifts superimposed on the long-ter...

GIS and Spatial Analysis

The objective of spatial analysis techniques is to describe the patterns existing in spatial data and to establish, preferably quantitatively, the relationships between different geographic variables. The notion of spatial analysis in a Geographic Information Systems (GIS) environment encompasses the idea of integrating spatial data and alphanumeric attributes and translating it into a series of functions relat...

Non-Steroidal Anti-Inflammatory Drug Hypersensitivity in Children

There are rather few publications about hypersensitivity reactions to non-steroidal anti-inflammatory drugs (NSAID) in the paediatric age. In this study, we aimed to assess the frequency of confirmed NSAID hypersensitivity in children with a previous reported reaction to NSAID in order to investigate the role of the drug provocation test (DPT) in the diagnostic workup and to explore the factors associated with ...

Validation of control of allergic rhinitis and asthma test for children (CARATK...

BACKGROUND: Control of Allergic Rhinitis and Asthma Test for Children (CARATKids) is the first questionnaire that assesses simultaneously allergic rhinitis and asthma control in children. It was recently developed, but redundancy of questions and its psychometric properties were not assessed. This study aimed to (i) establish the final version of the CARATKids questionnaire and (ii) evaluate its reliability, re...

Drug-Induced Anaphylaxis Survey in Portuguese Allergy Departments

Background and Objective: Drug-induced anaphylaxis is an unpredictable and potentially fatal adverse drug reaction. The aim of this study was to identify the causes of drug-induced anaphylaxis in Portugal. Methods: During a 4-year period a nationwide notification system for anaphylaxis was implemented, with voluntary reporting by allergists. Data on 313 patients with drug anaphylaxis were received and reviewed....

Anafilaxia Induzida por Fármacos: Registo Nacional 2007-2010

Introdução: A anafilaxia a fármacos constitui uma situação potencialmente fatal e imprevisível, desconhecendo -se a real prevalência em diferentes grupos populacionais e os factores de risco relacionados. Objectivo: Contribuir para o melhor conhecimento epidemiológico da anafilaxia induzida por fármacos no nosso país. Métodos: Durante um período de 4 anos (Janeiro de 2007 a Dezembro de 2010) foi implementado um...

Partial replacement of fish oil by soybean oil on lipid distribution and liver ...

A 12-week feeding trial was conducted to evaluate the effects of fish oil replacement by soybean oil, on lipid distribution and liver histology of two commercially important finfish species: rainbow trout (Oncorhynchus mykiss) and European sea bass (Dicentrarchus labrax). Sea bass (16.2 +/- 0.5 g; mean +/- SD) and rainbow trout (52.1 +/- 0.5 g) juveniles were fed one of three isonitrogenous (500 g kg(-1) CP) an...
