Clear-PEM: A PET imaging system dedicated to breast cancer diagnostics
Abreu, M. C.; Aguiar, D.; Albuquerque, E.; Almeida, F. G.; Almeida, P.; Amaral, P.; Auffray, E.; Bento, P.; Bruyndonckx, P.; Bugalho, R.; Carriço, B.The Clear-PEM scanner for positron emission mammography under development is described. The detector is based on pixelized LYSO crystals optically coupled to avalanche photodiodes and readout by a fast low-noise electronic system. A dedicated digital trigger (TGR) and data acquisition (DAQ) system is used for on-line selection of coincidence events with high efficiency, large bandwidth and small dead-time. A sp...
PCR with Paracoccidioides brasiliensis specific primers: potential use in ecol...
DÍEZ,S.; GARCIA,E.A.; PINO,P.A.; BOTERO,S.; CORREDOR,G.G.; PERALTA,L.A.; CASTAÑO,J.H.; RESTREPO,A.; McEWEN,J.G.The precise microenvironment of Paracoccidioides brasiliensis has not yet been discovered perhaps because the methods used are not sensitive enough. We applied to this purpose the polymerase chain reaction (PCR) using three sets of specific primers corresponding to two P. brasiliensis genes. This fungus as well as several other fungi, were grown and their DNA obtained by mechanical disruption and a phenol chlor...
