Validação cruzada da versão portuguesa do Índice de Funcionamento Sexual Feminino
Pechorro, P. S.; Vieira, R. X.; Calvinho, A. M.; Poiares, C.; Marôco, J.; Diniz, A.Introdução: O constructo de ciclo de resposta sexual constitui um modelo de trabalho essencial no campo do estudo da sexualidade feminina. Objectivo: A presente investigação teve como objectivo proceder à validação cruzada duma versão portuguesa do Índice de Funcionamento Sexual Feminino (FSFI), instrumen¬to multidimensional que avalia as diversas fases associadas ao ciclo de resposta sexual em mulheres.

Dropout in the treatment of erectile dysfunction with PDE5: a study on predicto...
Carvalheira, A. A.; Pereira, N. M.; Maroco, J.; Forjaz, V.INTRODUCTION: Phosphodiesterase type 5 inhibitors (PDE5) are currently the first line treatment for erectile dysfunction (ED). However, previous research shows that PDE5 treatments have high discontinuation rates. Understanding the reasons for discontinuing PDE5 will be necessary to optimize the response to treatment. AIM: The main goals were: (i) to analyze discontinuation rate of PDE5; (ii) to identify the di...
Leaf-level responses to light in two co-occurring Quercus (Quercus ilex and Que...
Vaz, Margarida; Maroco, J.; Ribeiro, Nuno; Gazarini, Luiz Carlos; Pereira, João Santos; Chaves, Maria ManuelaAbstract We studied morphological, biochemical and physiological leaf acclimation to incident Photon- Photosynthetic-Flux-Density (PPFD) in Quercus ilex (holm oak) and Quercus suber (cork oak) at Mediterranean evergreen oak woodlands of southern Portugal. Specific leaf area (SLA) decreased exponentially with increasing PPFD in both species. Q. ilex had lower SLA values than Q. suber. Leaf nitrogen, cellulose an...
Drought-induced photosynthetic inhibition and autumn recovery in two Mediterran...
Vaz, M.; Pereira, J.S.; Gazarini, L.C.; David, T.S.; David, J.S.; Rodrigues, A; Maroco, J; Chaves, M.M.Responses of leaf water relations and photosynthesis to summer drought and autumn rewetting were studied in two evergreen Mediterranean oak species, Quercus ilex spp. rotundifolia and Quercus suber. The predawn leaf water potential (ΨlPD), stomatal conductance (gs) and photosynthetic rate (A) at ambient conditions were measured seasonally over a 3-year period. We also measured the photosynthetic response to lig...
