Tese de mestrado em Física, apresentada à Universidade de Lisboa, através da Faculdade de Ciências, 2014 ; Colisões protão-chumbo constituem uma componente crucial para o estudo de fenómenos que ocorrem em colisões ultra-relativistas de chumbo-chumbo. Aquele tipo de colisões permite realizar medidas de referência para a compreensão de fenómenos produzidos no meio quente e denso do plasma de quarks e gluões, ta...
Introduction The production of artificial vascular grafts of small diameter is a fluorescing line of investigation. PVA is a biomaterial that has been used for several biomedical applications and nowadays as a vascular graft. However the mechanical properties were never characterized in vitro. It was our objective to produce small diameter PVA grafts and characterize their physical and mechanical properties for...
Introduction: The use of cellular systems for improving biointegration of medical devices is a current trend of tissue engineering. The biocompatibility is a key aspect that can influence the performance of medical devices, for that reason inflammatory and foreign body reaction must be evaluated in pre-clinical studies. MSCs can modify the interaction of biomaterials with tissues by several mechanisms through t...
Application of vascular grafts of the polyvinyl alcohol hydrogel (PVA) associated with MSCs from Wharton jelly in an animal model (sheep). N Alexandre, MA Lopes, N Fernandes, M Rodrigues, I Amorim, AC Mauricio, AL Luís Introduction: There is a great demand for new artificial vascular grafts of small diameter (< 6 mm) due to the functional limitations of the currently used biomaterials (ePTFE and Dacron). Polyv...
The purpose of this Master thesis is to contribute to the NEXT experiment (Neutrino Experiment with a Xenon Time Projection Chamber) by studying xenon based gaseous mixture properties. The work developed to study gaseous mixtures properties was based on three experimental setups: Ion Drift Chamber (IDC), Gas Proportional Scintillation Counter (GPSC) and Proportional Counter (PC). With the IDC, measurements of N...

This study reports a serological and molecular survey on the spotted fever group Rickettsia found in a group of 51 dogs with suspected tickborne illness from the south of Portugal. Additionally, a prevalence of IgG antibodies to R. conorii was also estimated in a group of 400 healthy dogs from the same region. In the group of healthy dogs, the immunofluorescence test revealed that 154 (38.5%) of the 400 dogs ha...
O autor apresenta uma revisão bibliográfica actualizada das evidências científicas que aconselham ou não o tratamento do trauma espinal em animais de companhia com corticosteroides.
