Scientific objects in the exhibition CHIMICA
Mendes, Paulo J.; Rosado, F.; Ferreira, T.; Conde, A.F.; Figueiredo, M.; Caldeira, A.T.; Valente, M.; Galacho, C.Secondary School André de Gouveia (ESAG) is frequently associated to Lyceu d’Évora from which it inherited the historical and cultural background. Lyceu d’Évora was established in 1841 after the educational reform of Passos Manuel and it was set at the Colégio do Espírito Santo, in Évora, until 1979. During that period, a physics and chemistry laboratory was created and developed at the Lyceu and it was enriche...
A Monte Carlo Study of the Electron Clouds Produced by Polarized X-Rays in Xenon
G.S. Botte; P.J.B.M. Rachinhas; T.H.V.T. Dias; F.P. Santos; L.M.N. Távora; R.M.Curado da Silva; C.A.N. Conde; A. D. StaufferInformation about the polarization of x-ray photons can be determined by probing the direction of emission of photoelectrons and the profile of the electron cloud produced in the detecting medium. In this work we present Monte Carlo results for the electron clouds produced in xenon by the absorption of x-rays, considering a simplenon-relativistic dipole approach to the angular differential photoionization cross...
Crescimento e actividade fetal às 20-24 semanas de gestação (estudo preliminar)
Conde, A.; Figueiredo, B.; Tendais, I.; Pereira, A.; Nogueira, R.BACKGROUND: Recent researches show that psychological development begins much before birth and prenatal influences can explain a significant part of the future variability in infants' behaviour and development. AIMS: The aim of this study was to characterize the fetal development between 20 and 24 weeks of gestation, related to the measures of fetal growth-- iparietal diameter, abdominal circumference, head ci...
Differential expression of the eukaryotic release factor 3 (eRF3/GSPT1) accordi...
Malta-Vacas, Joana; Aires, C.; Costa, P.; Conde, A. R.; Ramos, S.; Martins, A. P.; Monteiro, C.; Brito, MiguelBackground: There are now several lines of evidence to suggest that protein synthesis and translation factors are involved in the regulation of cell proliferation and cancer development. Aims: To investigate gene expression patterns of eukaryotic releasing factor 3 (eRF3) in gastric cancer. Methods: RNA was prepared from 25 gastric tumour biopsies and adjacent non-neoplastic mucosa. Real time TaqMan reverse tra...
Intoxicação por Monóxido de Carbono
Conde, A; Alegria, A; Neto, AO monóxido de carbono é uma das principais causas de intoxicação, podendo ser letal ou levar a sequelas neuropsicológicas tardias. A intoxicação manifesta-se por sintomas pouco especificos, pelo que o seu diagnóstico exige um elevado índice de suspeição. 0 doseamento de carboxihemoglobina e útil, mas apresenta uma fraca correlação quer com a clínica, quer com o prognóstico. O tratamento baseia-se na oxigenação...
Interruption of recently induced immune responses by oral administration of ant...
Conde,A.A.; Stransky,B.; Faria,A.M.C.; Vaz,N.M.Interest in oral tolerance has been renewed in the last few years as a possibility of intervention in human autoimmune diseases. An obstacle in this direction is that, although easily induced in animals virgin of contact with the antigen, oral tolerance becomes hard to induce in previously immunized animals. The present results show that there is an early period after primary immunization in which prolonged ora...
Revascularization and reimplantation of the upper extremity. 15-year-experience...
Malheiro, E; Serviço de Cirurgia Plástica e Reconstrutiva, Hospital de S. João, Porto.; Amarante, J; Reis, J; Silva, A; Conde, A; Choupina, MProgress in micro or macro replantation has resulted in higher survival rates of formerly amputated parts. More amputated digits or limbs survive because the time of ischemia can be exceeded by using cold storage or perfusion. Homo or heterodigital vessel transposition, expanded indications for vein graft interposition, as well as heterotopic transplantation allow for extremity preservation even in crush injuri...
Microsurgical reconstruction of the upper extremity. Experience with 24 free fl...
Costa, H; Serviço de Cirurgia Plástica e Reconstrutiva, Hospital de S. João, Faculdade de Medicina do Porto.; Pinto, A; Cunha, C; Conde, A; Guimarães, IThe authors present the experience of 24 clinical cases of microsurgical reconstruction of the upper limb. These reconstructions were accomplished by different microvascular free flaps which were selected according to the type, size and location of the defects, having applied fasciocutaneous, adipofascial, myo, myocutaneous, tendofasciocutaneous, omentum flaps and 2nd toe transfers. The etiology was traumatic i...
Microsurgical reconstruction of the head and neck: experience of 63 free flaps.
Costa, H; Serviço Cirurgia Plástica, Hospital S. João, Porto.; Guimarães, I; Cunha, C; Conde, A; Luz, M; Pinto, A; Pinho, C; Freitas, A; Rodrígues, JThe authors present the experience of 63 clinical cases of microsurgical reconstruction of the head and neck. These reconstructions were accomplished by different microvascular free flaps which were selected according to the type, size and location of the defects. Fasciocutaneous, osteofasciocutaneous, adipofascial, myo, myocutaneous, myosseous, jejunum and great omentum flaps were applied. The etiology was tra...
Reconstruction of the anterior cranial base with a frontal muscle flap in cereb...
Costa, H; Serviço de Cirurgia Plástica e Reconstrutiva, Hospital S. João, Porto.; Cunha, C; Conde, A; Cerejo, A; Baptista, A; Vaz, R; Gonçalves, MCraniofacial infection is a major problem for the plastic and neurosurgical team. Previous successful experiences with free muscle and omentum flaps and the galea frontalis myofascial flap have been reported, avoiding disastrous complications after frontofacial advancements and the resection of skull base tumors. The authors report the clinical use of the galea frontalis myofascial flap in the treatment of ante...
