One of the obstacles to more frequent and appropriate use of cardiac magnetic resonance (CMR) in Portugal has been the lack of specific codes that accurately describe these examinations as they are currently performed. In this consensus document, recommendations are made for updating and standardizing CMR codes in Portugal. Guidance on which techniques and codes should be used in the most common clinical scenar...
The effects of mercury contamination on the population structure and dynamics of the gastropod Peringia ulvae (also known as Hydrobia ulvae) and its impact on the trophic web were assessed along a mercury gradient in Ria de Aveiro (Portugal). The gastropod was revealed to be a tolerant species to the contaminant, since the highest densities, biomasses and growth productivity values were recorded at the intermed...
Um dos obstáculos a uma utilização mais frequente e apropriada da ressonância magnética cardíaca (RMC) em Portugal tem sido a ausência de códigos específicos que descrevam adequadamente os exames tal como são efetuados actualmente. Este documento de consenso fornece recomendações para a atualização e uniformização dos códigos empregues na RMC. São igualmente feitas recomendações quanto às técnicas e códigos a u...
Screening for coronary artery disease (CAD) in the asymptomatic diabetic patient is controversial with respect to both patient selection and rational choice of screening methods. Epidemiological studies in the real world and improved knowledge on risk markers have changed the criteria that help refine global risk stratification in a patient population that is per se high risk. Over the past years, it is likely ...
RESUMO Introdução: A infeção urinária é uma patologia comum em idade pediátrica. A antibioterapia deve ser iniciada empiricamente antes do isolamento do agente causal e os fármacos utilizados devem ter em conta os microrganismos e o padrão de resistência local. Objetivos: Identificação dos agentes etiológicos de infeção urinária e os seus padrões de resistência antibiótica no nosso hospital. Material e Métodos:...
Members of the WNK (with no lysine (K)) subfamily of protein kinases regulate various ion channels involved in sodium, potassium and chloride homeostasis by either inducing their phosphorylation or regulating the number of channel proteins expressed at the cell surface. Here, we describe that WNK4 promotes the cell surface expression of the cystic fibrosis transmembrane conductance regulator (CFTR) in mammalian...
Prémio de Investigação Básica ; One mechanism by which cells regulate the uptake of glucose is the number of glucose transporter proteins (GLUT) present at the plasma membrane. In insulin-responsive cells types, GLUT4 is released from intracellular storage vesicles through inactivation of the Rab GTPase activating protein TBC1D4, also known as AS160. Using protein biochemical techniques we analysed complex for...
Previously, the pleiotropic "master kinase" casein kinase 2 (CK2) was shown to interact with CFTR, the protein responsible for cystic fibrosis (CF). Moreover, CK2 inhibition abolished CFTR conductance in cell-attached membrane patches, native epithelial ducts, and Xenopus oocytes. CFTR possesses two CK2 phosphorylation sites (S422 and T1471), with unclear impact on its processing and trafficking. Here, we inves...
De acordo com a teoria da vinculação, a qualidade da relação com as figuras parentais desempenha um papel fundamental na forma como os jovens se percebem a si e aos outros, contribuindo a qualidade destes laços para o desenvolvimento da auto-estima e dos laços que se constroem posteriormente com os pares. O objectivo deste estudo é observar a contribuição da qualidade da vinculação à mãe na predição da ligação ...
