Pestana, M. H. G.; Parreira, A. M.; Parreira, C. M.; Gageiro, J. N.; Silva, J. P.O objectivo deste artigo é examinar os hábitos de estudo e os estilos de aprendizagem entre os alunos do primeiro ano que frequentam universidades públicas e compará-los com os que frequentam universidades privadas, tendo em vista identificar os atributos desses estudantes que podem influenciar a adopção de um ou outro estilo. A compreensão destas diferenças por parte dos professores permite uma maior probabili...
Endothelial function in patients with metabolic syndrome and erectile dysfuncti...
Tomada, Nuno; Tomada, Inês; Botelho, Francisco; Figueiredo, Luís Pacheco; Lopes, T.; Negrão, R.; Pestana, M.; Cruz, F.Erectile dysfunction (ED) is a highly prevalent disease whose aetiology is mostly vasculogenic. It is nowadays considered a marker of future cardiovascular events reflecting the underlying endothelial dysfunction, the common link with the metabolic syndrome (MetS). The recent association between MetS, endothelial dysfunction and peripheral artery disease, but not with coronary artery disease (CAD), suggests tha...

The pinewood nematode, Bursaphelenchus xylophilus, in Madeira Island
Fonseca, L; Cardoso, J.M.S.; Lopes, A; Pestana, M; Abreu, F; Nunes, N; Mota, Manuel; Abrantes, IsabelThe environmental conditions in Madeira Island are favorable for the presence and dissemination of the pinewood nematode (PWN), Bursaphelenchus xylophilus. Five hundred Pinus pinaster wood samples were collected in several forest areas and PWN was detected in 22.8 % of the samples. Bursaphelenchus xylophilus isolates from Madeira Island displayed the species-specific diagnostic characters. A morphological varia...
Development and recovery of iron deficiency by iron resupply to roots or leaves...
Pestana, M.; Correia, P. J.; Saavedra, Teresa; Gama, Florinda; Abadía, Anunciación; Varennes, Amarilis deBare-root transplants of strawberry (Fragaria ananassa Duch. cv. ‘Selva’) were transferred to nutrient solutions with or without iron (Fe). After six weeks of growth, plants grown in solution lacking Fe were chlorotic and showed morphological changes in roots typical of Fe deficiency. Subsequently, four treatments were applied for nine days: plants grown in continued absence of Fe (Fe0); plants grown in continu...
The root ferric-chelate reductase of Ceratonia siliqua (L.) and Poncirus trifol...
Pestana, M.; Gama, Florinda; Saavedra, Teresa; Varennes, Amarilis de; Correia, P. J.Iron (Fe) deficiency is a common nutritional disorder in several crops grown in calcareous soils, but some species are well adapted to these conditions. A hydroponic experiment was conducted to compare the response of a calcicole species Ceratonia siliqua L. (carob) and of Poncirus trifoliata (L.) Raf., a citrus rootstock very sensitive to Fe deficiency. Rootstocks from both species were grown in nutrient solut...

Pestana, M.; Varennes, Amarilis de; Miguel, Maria Graça; Correia, P. J.Proceedings of the International Conference “Environmentally friendly and safe technologies for quality of fruit and vegetables”, held in Universidade do Algarve, Faro, Portugal, on January 14-16, 2009. This Conference was a join activity with COST Action 924. ; Iron deficiency (iron chlorosis) is an important nutritional disorder in several plants, including fruit trees and strawberry. Iron chlorosis does not...
