Effect of Foliar Application of Nitrogen-Fixing Microorganisms and Algae Extrac...
Arrobas, Margarida; Roque, João; Martins, Sandra; Brito, Cátia; Correia, Carlos Manuel; Rodrigues, ManuelThis study presents the results of two on-farm trials evaluating the efficacy of a nitrogen (N)-fixing inoculant (Methylobacterium symbioticum) applied as a foliar spray to provide N to hazelnut (Corylus avellana L.) and walnut (Juglans regia L.) trees. In the hazelnut trial, a factorial design was employed with soil N application at three levels [0 (N0), 40 (N40), and 80 (N80) kg ha−1] and foliar application o...
A Spray Foliar Containing Methylobacterium symbioticum Did Not Increase Nitroge...
Rodrigues, Manuel Ângelo; Lopes, João Ilídio; Martins, Sandra; Brito, Cátia; Correia, Carlos Manuel; Arrobas, Margarida; Rodrigues, ManuelBiological nitrogen (N) fixation has been advocated in agricultural fields due to being considered a more sustainable way to introduce N into agrosystems than industrial N fertilizers. In this study, a foliar spray inoculant containing the microorganism Methylobacterium symbioticum was applied. This microorganism is known for fixing N in the phyllosphere, regardless of the cultivated species. This study was con...
Biomass and nutrient release dynamics of decomposing rolling down legume cover ...
Brito, Cátia; Martins, Sandra; Saraiva, Francisco; Roque, João; Arrobas, Margarida; Rodrigues, Manuel Ângelo; Correia, CarlosWell-managed cover crops are gaining traction as an alternative to conventional tillage, offering a range of agronomic and ecological benefits. This field study, conducted in a commercial vineyard in the Douro region (Portugal) during the 2022/2023 growing season, evaluated the decomposition dynamics and nutrient release from different legume cover crop residues over a period of 183 days after sowing and 114 da...
Foliar Silicon Application in the Era of Climate Change as a Part of Strategy t...
Dinis, Lia Tânia; Mota, Natalia; Martins, Sandra; Ribeiro, A.C.; Moutinho-Pereira, José; Pereira, SandraRising temperatures and water scarcity due to climate change are significant challenges for Mediterranean viticulture, particularly in the Douro Valley, a prominent winemaking region. Silicon (Si) has gained attention as a potential solution for mitigating these environmental stresses, especially in areas with limited water resources. This study explores the foliar application of Si as a promising strategy to r...
Impact of a daily legume-based meal on blood and anthropometric parameters in a...
Ferreira, Helena; Vasconcelos, Marta; Gil, Ana M.; Silveira, Joana; Alves, Paulo; Martins, Sandra; Assunção, Marco; Guimarães, João TiagoThis pilot study aimed to assess the impact of substituting a traditional lunch for a vegetarian legume-based meal on blood and anthropometric parameters in a group of omnivorous adults. A one-group comparison, quasi-experimental dietary intervention was designed. A vegetarian legume-based meal was offered for 8 consecutive weeks (weekdays) to non-vegetarian individuals (n = 26), (28 years [P25 = 20.0, P75 = 35...
Differential responses of photosynthesis, yield and soil properties 4 years aft...
Martins, Sandra; Brito, Cátia; Gonçalves, Alexandre; Moutinho-Pereira, José; Pereira, Ermelinda; Arrobas, Margarida; Rodrigues, M.A.; Nunes, FernandoOlive orchards represent a key agricultural system in the Mediterranean Basin. Soil degradation processes associated with 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. In...
An innovation project at the IPB: higher education for all
Semedo, José; Martins, Cláudia; Rocha, João; Santos, Jorge; Martins, SandraEpistemologically speaking, higher education (HE) is oftentimes regarded as a place of “receiving” knowledge and skills rather than “giving”, a place of watching creation happen rather than participating in this creation process. However, in the new millennium, HE institutions have gradually been rediscovering constructivism and broadening its scope to a more participatory approach. Thus, cocreation ecosystems,...
From creation to cocreation: culture for all Bragança
Castro, José Luís; Martins, Cláudia; Martins, Sandra“Culture for All Bragança” was a large-scale ambitious project designed by the Municipality of Bragança (with funding from the European Social Fund) that was conducted by the IPB. A team of professors-reseachers, junior researchers and collaborators with impairments was in charge of creating a considerable number of accessible resources that were to serve as mediation for anyone visiting 5 of the city’s cultura...
Generation of induced pluripotent stem cell lines from two unrelated individual...
Ribeiro, Marta; Martins, Sandra; Carvalho, Teresa; Furtado, Marta; Cabral, Joaquim M.S.; Brito, Dulce; Carmo-Fonseca, Maria; da Rocha, Simão T.Familial hypertrophic cardiomyopathy (HCM) is the most common inherited heart condition. HCM patients show left ventricle hypertrophy without any associated loading conditions, being at risk for heart failure and sudden cardiac death. Two induced pluripotent stem cell (iPSC) lines were generated from peripheral blood mononuclear cells obtained from two unrelated individuals, a 54-year-old male (F81) and a 44-ye...
The Impact of Sarcopenia in the Prognosis of Patients with Gastric Cancer Under...
Barros, Daniela Moreira; Pinheiro, Gisela Moreira; Costa, Catarina; Martins, SandraIntroduction: Surgical treatment is the first-line treatment for patients with resectable gastric cancer. The impact of preoperative sarcopenia on the post-operative outcomes of these patients remains unclear. In this context, we evaluate the association between the presence of sarcopenia and the prognosis of patients with gastric cancer undergoing surgery. Methods: It was conducted a retrospective, observation...
