Peroral esophageal segmentectomy and anastomosis with single transthoracic troc...
Rolanda, C; Silva, D; Branco, C; Moreira, I; Macedo, G; Correia-Pinto, JBACKGROUND AND STUDY AIMS: A transesophageal natural orifice transluminal endoscopic surgery (NOTES) approach has been proposed for thoracic and mediastinal access. Similarly to transgastric surgery, serious limitations remain related to creating an esophagotomy and its safe closure. A hybrid approach in thoracic NOTES could work as an intermediate step before pure transesophageal NOTES. We assessed the benefit...

Impacte ambiental da Central Termoeléctrica do Pego, na perspectiva de alunos d...
I.Macedo; D. FloresThe environmental impact of the Pego Power Plant, which produces energy using coal as fuel, is the subject of this study using a group of 25 students from 8th grade. This study showed that the School plays a key role in information and dissemination/awareness, presenting a major role in the development of skills in the Environmental Education area
Cultivo in vitro de somaclones de abacaxizeiro na presença de NaCl
Brito,Lucila K. F. L. de; Moura,Gioconda E. D. D.; Martins,Camila P.; Aloufa,Magdi A. I.; Macedo,Cristiane E. C.; Lopes,Daniela B.; Barroso,Paulo A. V.Neste trabalho foi avaliado o cultivo in vitro de somaclones de abacaxizeiro, na presença de elevadas concentrações de NaCl. Propágulos de abacaxizeiro foram submetidos a um período de cultivo in vitro em diferentes concentrações de NaCl (0, 12,5, 25 e 50 mM). Em seguida, foram cultivados na ausência do sal e, por fim, foram submetidos a um outro período de cultivo in vitro em 0 e 100 mM de NaCl. Não se observo...
Third-generation cholecystectomy by natural orifices: transgastric and transves...
Rolanda, C; Lima, E; Pêgo, JM; Henriques-Coelho, T; Silva, D; Moreira, I; Macedo, G; Carvalho, JL; Correia-Pinto, JBACKGROUND: An isolated transgastric port has some limitations in performing transluminal endoscopic cholecystectomy. However, transvesical access to the peritoneal cavity has recently been reported to be feasible and safe. OBJECTIVE: To assess the feasibility and the technical benefits of transgastric and transvesical combined approach to overcome the limitations of isolated transgastric ports. DESIGN: We crea...

An RPC-PET prototype with high spatial resolution
Blanco, A.; Carolino, N.; Correia, C. M. B. A.; Marques, R. Ferreira; Fonte, P.; González-Díaz, D.; Lindote, A.; Lopes, M. I.; Macedo, M. P.A small positron emission tomography system, based on the timing RPC technology has been built and tested. This first prototype is aimed at validating the expectations, derived from simulations, of a very high spatial resolution, which could be of value for the imaging of small animals. The system is composed of two counting heads, able to measure the photon interaction point in two dimensions, the transaxial d...
Comparison of different monoclonal antibodies against immunosuppressive protein...
Oshiro,T.M.; Rafael,A.; Enobe,C.S.; Fernandes,I.; Macedo-Soares,M.F.The extract of Ascaris suum suppresses the humoral and cellular immune responses to unrelated antigens in the mouse. In order to further characterize the suppressive components of A. suum, we produced specific monoclonal antibodies which can provide an important tool for the identification of these proteins. The A. suum immunosuppressive fractions isolated by gel filtration from an extract of adult worms were u...
