Combining zeolites with early-maturing annual legume cover crops in rainfed orc...
Martins, Sandra; Silva, Ermelinda; Brito, Cátia; Pinto, Luís; Martins-Gomes, Carlos; Gonçalves, Alexandre; Arrobas, Margarida; Rodrigues, M.A.Under climate change threats, there is a growing need to adapt the conventional agronomic practices used in rainfed olive orchards by sustainable practices, in order to ensure adequate crop yield and olive oil quality and to preserve soil health. Therefore, for two years, the effects of conventional tillage practice (T) and two sustainable soil management strategies, a leguminous cover crop (LC) and its combina...
Zeolites and Biochar modulate olive fruit and oil polyphenolic profile
Martins, Sandra; Silva, Ermelinda; Brito, Cátia; Martins-Gomes, Carlos; Gonçalves, Alexandre; Arrobas, Margarida; Rodrigues, M.A.; Correia, Carlos M.Soil degradation processes and climate change threaten the sustainability of Mediterranean rainfed olive orchards, with repercussions on crop yield and quality of olives, olive oil and olive by-products. Using soil amendments can enhance soil fertility for sustained environmental quality and plant performance. For two years, we evaluated, under rainfed conditions, the effects of a fertilizer compound (FC) and i...
Improving the sustainability of rainfed olive orchards by using zeolites and ea...
Martins, Sandra; Silva, Ermelinda; Brito, Cátia; Pinto, Luís; Martins-Gomes, Carlos; Gonçalves, Alexandre; Arrobas, Margarida; Rodrigues, M.A.Olive cultivation is considered as one of the most significant agricultural activities in Mediterranean region, from a financial, social and ecological point of view. Under climate change threats, there is a growing need to adapt the conventional agronomic practices used in rainfed olive orchards by sustainable practices, in order to preserve soil health, while ensure olive tree performance and olive oil qualit...
Soil amendment with Zeolites and Biochar influenced soil properties, photosynth...
Martins, Sandra; Silva, Ermelinda; Brito, Cátia; Martins-Gomes, Carlos; Gonçalves, Alexandre; Arrobas, Margarida; Rodrigues, M.A.; Nunes, Fernando M.Olive orchards represent a key agricultural system in the Mediterranean basin. Soil degradation processes associated to unsustainable agronomic practices and climate change could severely impact the sustainability of Mediterranean rainfed olive orchards. In this context, soil amendments are important tools that can be used to enhance soil fertility for sustained environmental quality and plant performance. For ...
Orange thyme: Phytochemical profiling, in vitro bioactivities of extracts and p...
Silva, Amélia M.; Félix, Luís M; Teixeira, Isabel; Martins-Gomes, Carlos; Schäfer, Judith; Souto, Eliana B.; Santos, Dario J; Bunzel, MirkoOrange thyme (Thymus fragrantissimus) is becoming widely used in food as a condiment and herbal tea, nevertheless its chemical composition and potential bioactivities are largely unknown. Thus the objective of this work is to obtain a detailed phytochemical profile of T. fragrantissimus by exhaustive ethanolic extraction and by aqueous decoction mimicking its consumption. Extracts showed high content in rosmari...
Red seaweeds strengthening the nexus between nutrition and health: phytochemica...
Ferreira, João; Hartmann, Anja; Martins-Gomes, Carlos; Nunes, Fernando M.; Souto, Eliana B.; Santos, Dario L.; Abreu, Helena; Pereira, RuiThe red seaweeds Grateloupia turuturu and Porphyra umbilicalis are commonly used as human food, mainly in East Asia, being valuable nutritional sources. However, studies focusing on their composition and bioactivities are scarce. Thus, G. turuturu and P. umbilicalis hydroethanolic and water (infusion and decoction) extracts were prepared to characterize their bioactive compounds; assess antioxidant activity aga...

Thymus zygis subsp. zygis an Endemic Portuguese Plant: Phytochemical Profiling,...
Silva, Amélia M.; Martins-Gomes, Carlos; Souto, Eliana B.; Schäfer, Judith; Santos, João A.; Bunzel, Mirko; Nunes, Fernando M.Thymus zygis subsp. zygis is an endemic Portuguese plant belonging to the Thymus zygis species. Although T. zygis is commonly used as a condiment and as a medicinal herb, a detailed description of the polyphenol composition of hydroethanolic (HE) and aqueous decoction (AD) extracts is not available. In this work, we describe for the first time a detailed phenolic composition of Thymus zygis subsp. zygis HE and ...
Diabetic Retinopathy and Ocular Melanoma: How Far We Are?
Souto, Eliana B.; Campos, Joana R.; Ana, Raquel da; Fangueiro, Joana F.; Martins-Gomes, Carlos; Durazzo, Alessandra; Lucarini, MassimoDiabetic retinopathy causes vascular damage to retinal neurons, presenting characteristics of chronic inflammation. The development of new therapies capable of combating vision loss involves knowledge of inflammatory retinal changes. Studies in animal models and patients with diabetes have shown a high expression of the inflammatory molecules that are involved in the progression of diabetic retinopathy. Uveal m...
