1. Acute and long-term effects of pulmonary embolism on heart function and lung circulation
Abstract : Objectives: To describe the course over time of pulmonary artery systolic pressure (PAsP) and right ventricle (RV) function assessed with echocardiography-Doppler (E-D) and extent of perfusion defects (PDf) on lung scintigraphy (LS) and to identify patients at increased risk for death or for chronic pulmonary hypertension (PH), after pulmonary embolism (PE). Design: Prospective follow-up studies with cross-sectional analyses. READ MORE

2. The Wnt pathway in ventral midbrain dopaminergic differentiation
Abstract : Parkinson’s disease (PD) is a debilitating neurodegenerative disease in which dopaminergic (DA) neurons in the substantia nigra are lost. Current treatments such as administration of levodopa (L-DOPA) are initially effective but the disease eventually progresses, highlighting the need for a treatment that restores and maintains the otherwise lost functions.

3. Diagnosis in evolvable production systems
Abstract : Esta tese aborda a problem�tica da execu��o de diagn�stico em instala��es industriais complexas que s�o compostas por um elevado n�mero de componentes que interagem entre si no �mbito do processo de produ��o.Apesar da abordagem apresentada ao problema ser geral e aplic�vel a v�rias classes de sistemas ligados em rede, o dom�nio dos Sistemas Evolutivos de Produ��o e os Sistemas Evolutions de Assembly (EPS/EAS) � utilizado como a base sobre a qual o sistema de diagn�stico proposto � implementado.

4. Finite element modelling of the mechanics of solid foam materials
Abstract : Failure of bi-material interfaces is studied with the aim to quantify the influence of the induced stress concentrations on the strength of the interfaces. A simple point-stress criterion, used in conjunction with finite element calculations, is evaluated to provide strength predictions for bi-material bonded joints and inserts in polymer foam.
