The use of a centralised planning scheduler in fieldbus-based systems requiring real-time operation has proved to be a good compromise between operational flexibility and timeliness guarantees.In this paper a preliminary implementation of a hardware scheduling coprocessor based in the planning paradigm is presented. The coprocessor is installed in a special node of the fieldbus, the bus arbiter, and generates s...
BACKGROUND: self-expanding metal stents are currently being used as a definitive palliative treatment for malignant colorectal obstruction in patients with incurable disease. Few studies have followed large numbers of patients from stent placement until death, and those few have reported conflicting results in the long-term clinical outcome data. AIMS: this study evaluated the clinical effectiveness of stent p...
We describe the case of a patient with long-standing Parkinson’s disease and recurrent bilateral pleural effusions. The pleural fluid was an exudate, rich in normal lymphocytes, and the echocardiogram, chest computerized axial tomography, and immunological, microbiological and cytological studies were negative. The patient had been taking bromocriptine, which can be related to chronic pleural effusions. Using P...

Cationic liposomes/DNA (lipoplexes) have been widely used as non-viral vectors for transfection, the role of the neutral lipid in liposome formulation being determinant for the efficiency of this process [1,2]. In this work, we studied the potential of monoolein (MO) as helper lipid for cellular transfection. Lipoplexes composed of pDNA and dioctadecyldimethylammonium bromide (DODAB)/1-monooleoyl-rac-glycerol (...
This study determined the effects of gallium-aluminum-arsenide laser (GaAlAs), gallium-arsenide laser (GaAs) and Dersani® healing ointment on skin wounds in Wistar rats. The parameters analyzed were: type I and III collagen fiber concentrations as well as the rate of wound closure. Five wounds, 12 mm in diameter, were made on the animals’ backs. The depth of the surgical incision was controlled by removin...
A relação entre os parâmetros magnéticos e os teores de elementos seleccionados (Fe, Mn, Zn, Pb, Cu e Cr) em folhas de Nerium oleander L. e solos da cidade de Viseu constitui o objectivo fundamental deste trabalho. Nos solos a susceptibilidade magnética é indicadora da concentração em Fe, Cu e Mn. Nas folhas os parâmetros magnéticos são indicadores da concentração em Fe, Cu, Pb e Zn, sugerindo uma contribuição ...
