- The grapevine defencesPublication . Borges, Alexandre Filipe Guerreiro; Ferreira, Ricardo Boavida; Lourenço, Ana Maria; Monteiro, SaraGrapevine is one of the most cultivated fruit crop worldwide with Vitis vinifera being the species with the highest economical importance due to the high quality standards of its berries. Nonetheless, it is also the most susceptible Vitis species to fungal pathogens. Among others, relevant fungal diseases currently threatening grapevine cultures are powdery mildew, caused by Erysiphe necator, and esca, a disease complex comprised of several fungi in which Phaeomoniella chlamydospora and Phaeoacremonium aleophilum participate.(...)
- Exploring the bioavailability of (poly)phenols from berries and their potential activities in humansPublication . Pimpão, Rui; Ferreira, Ricardo Boavida; Santos, Cláudia Nunes(Poly)phenols are the most widely distributed secondary metabolites, in plants, and, therefore, are regular constituents of human food products. The regular ingestion of (poly)phenol-containing foods has been associated with a reduced risk of acquiring chronic diseases and many studies are currently trying to corroborate this theory. However, the precise contribution of (poly)phenols to disease prevention is still unknown.(...)
- Evaluation of neuroprotective potential of plyphenols derived from Portuguese native plants: Juniperus sp. and Rubus sp.Publication . Tavares, Lucélia Rodrigues; Ferreira, Ricardo Boavida; dos Santos, Maria Cláudia NunesNeurodegenerative diseases have become a challenge to modern societies in industrialized countries due to the high social and economic impacts and therefore demand intensive research. These diseases present diverse common features, in which oxidative stress plays a very important role. As result of oxidative stress, some molecular mechanisms become dysfunctional and ultimately lead to cell death. Amongst the compounds displaying neuroprotective activity, phenolics have been identified amongst the most active substances from natural sources.(...)
