Characterization and phytoremediation of abandoned contaminated mining area in ...
Canha, N.; Freitas, M.C.; Anawar, H.M.; Dionísio, I.; Dung, H.M.; Pinto-Gomes, Carlos; Bettencourt, A.This study aims to find out a vascular plant species that accumulate relatively high concentrations of arsenic (As) for its use as phytoremediator ar abandoned and contaminated mining areas, such as São Domingos mines (Portugal). The assessement of As contamination levels in soils and plants of other similar sites in the north of the coutry (Castromil ando Poço de Freitas) was also conducted and the sample anal...
Determination of phytoextraction potential of plant speciesfor toxic elements i...
Freitas, M. C.; Pacheco, A. M. G.; Anawar, H. M.; Dionísio, I.; Dung, H. M.; Canha, N.; Bettencourt, A.; Henriques, F.; Pinto-Gomes, CarlosThis study has determined contamination levels in soils and plants from the Sa˜o Domingos mining area, Portugal, by k0-INAA. Total concentrations of As, Sb, Cr, Hg, Cu, Zn and Fe in soils were very high, exceeding the maximum limits in Portuguese legislation. Concentrations of toxic elements like As, Sb and Zn were highest in roots of Erica andevalensis, Juncus acutus, Agrostis castellana and Nicotiana glauca. ...
Equilibrium radionuclide angiography in patients with previous myocardial infar...
Macieira-Coelho, E; Hospital Universitário de Santa Maria, Centro de Cardiologia da Universidade de Lisboa.; Carvalho, M; Dionísio, I; Prudêncio, AFifty five patients with previous myocardial infarction (MI), 47 male and 8 female, mean age 55.5 +/- 8.9 years, have been studied in order to correlate the alterations found on the equilibrium (gated) radionuclide angiogram (RNA) with the location of the MI on the electrocardiogram of the obstructive lesions on coronary angiographies. Of the 55 patients studied, 22% showed no regional wall motion abnormalities...
Coronary artery disease, myocardial perfusion and ventricular function in Q-wav...
Macieira-Coelho, E; Hospital Universitário de Sta. Maria, Serviço de Medicina III/IV., Lisboa.; Garcia-Alves, M; da Costa, B; Cantinho, G; Pedro, PControversy remains in considering non-Q wave myocardial infarction (NQMI) a distinct pathophysiological entity of Q wave myocardial infarction (QMI). In order to analyze the severity of coronary artery disease, extension of myocardial scar or myocardial ischemia and ventricular function, 78 consecutive patients with QMI and 32 with NQMI, mean age 55.4 +/- 8.5, not submitted to thrombolytic therapy, were studie...
Significance exercise-induced ST elevation in patients with myocardial infarcti...
Carvalho, M; Serviço de Medicina IV-H.S.M., Instituto de Medicina Nuclear-F.M.L INIC-LA3, Lisboa.; Cantinho, G; de Lacerda, A P; Dionísio, IIn 52 patients with previous myocardial infraction, 49 men and 3 women (mean age 56 +/- 7.1 years) the significance of ST-segment elevation during the stress-test, was evaluated. Of the 52 patients 15 (29%) showed St-segment elevation and 37(71%), showed no alteration of the ST-segment. Extension of coronary disease, degree of obstruction, wall motion abnormalities and the presence of residual ischemia were eva...
