Evapotranspiration from a Mediterranean evergreen oak savannah: The role of tre...
Paço, Teresa A.; David, Teresa S.; Henriques, Manuel O.; Pereira, João S.; Valente, Fernanda; Banza, João; Pereira, Fernando L.; Pinto, ClaraMediterranean evergreen oak woodlands of southern Portugal (montados) are savannah-type ecosystems with a widely sparse tree cover, over extensive grassland. Therefore, ecosystem water fluxes derive from two quite differentiated sources: the trees and the pasture. Partitioning of fluxes according to these different sources is necessary to quantify overall ecosystem water losses as well as to improve knowledge o...
Análise da função respiratória na doença de Parkinson
Cardoso,Sônia R.X.; Pereira,João S.Avaliou-se a função respiratória de 40 parkinsonianos (P), entre 50 e 80 anos, nos estágio I a III da Escala de Hoehn e Yahr e de 40 não parkinsonianos (NP), com características semelhantes. A amplitude torácica de 1,8±0,8 cm nos P foi menor que 4,3±1,0 cm nos NP (p=0,00001), assim como os percentuais das capacidades vital e vital forçada de 66,8±20,3% e 69,6±22,2% nos P e de 82,3±15,7% e 82,7±16,6% nos NP (p=0...
Essential tremor: clinical observations
Pereira,João S.; Pimentel,Maria Lúcia V.; Nicaretta,Denise H.The authors have studied 53 patients with essential tremor, focusing its clinical and epidemiological aspects. There were familial history in 37.70% of all cases, prevailing in females (56.60%) and white people (69.80%); nevertheless this difference can not be assured from the statistical point of view due to lack of population data. We agreed that the main incidence of this syndrome occurred beyond the 5th dec...
A study on the action of two calcium channel blockers (verapamil and flunarizin...
Pereira,João S.; Bertolucci,Paulo H. P.; Ferraz,Henrique B.; Andrade,Luiz A. F. deTardive dyskinesia (TD), a serious complications of neuroleptic chronic use, has no effective therapy yet. We performed an experiment to study the action on TD, of the calcium channel blockers (CCB) drugs, verapamil and flunarizine. We obtained the TD model in rats, administering haloperidol for a 21-day period. After this, the stereotyped movement induced by apomorphyne was rated. The CCB drugs were administer...
The action of prolyl-leucyl-glycinamide (PLG) on the nigrostriatal pathway of t...
Pereira,João S.; Andrade,Luiz Augusto F.; Bertolucci,Paulo H. F.; Lima,J. Geraldo Camargo; Ferraz,Henrique B.In order to study the nigrostriatal pathway, we obtained the rotatory behavior model in male Wistar rats by electrolytic lesion of the left lateral hypothalamic region. Animals thus lesioned displayed rotations toward the same side of lesion when apomorphine was administered, a result in disagreement with what has been obtained in the model with 6-hydroxydopamine lesion. The administration of PLG alone was not ...
