Vesicoperineal Fistula: A Rare Rectal Cancer Treatment Complication
Moreira, Luísa; Margarida, André; Vasconcelos, Marta; Garção, Nunes; Luz, CarlosA vesicoperineal fistula is an uncommon entity, described as an aberrant tract between the bladder lumen and the cutaneous surface of the perineum. We present the case of a 78-year-old male who underwent abdominoperineal resection and chemoradiotherapy for the treatment of non-metastatic, locally advanced rectal cancer. Five years later, he developed a pelvic floor hernia and underwent perineal mesh repair. A f...
Lignin from grape stalks: nanoparticle production through sonication
Cassoni, Ana C.; Bourbon, Ana Isabel Juncá Sottomayor Lisboa; Vasconcelos, Marta; Pintado, ManuelaLignin nanoparticles represent an emerging class of sustainable nanomaterials that can improve the valorisation of this abundant biopolymer through new applications [1 ]. This study focused on optimizing the production of lignin nanoparticles through sonication, using minimal amount of chemicals possible, while achieving small particle size and maintaining colloidal stability.
Mass tourism, cultural heritage, and traditional values within citizen lifestyl...
Vieira, Eduarda; Pelaez, Ana; Rosa, Inês; Lemos, Teresa; Bordalo, Rui; Vasconcelos, Marta; Moreira, PatríciaPorto has a rich urban mesh and unique cultural identity, whose preservation has been the basis of its historic centre classification as a World Heritage Site by UNESCO (1996). The increase in demand of Porto as a tourism destination since 2015 was simultaneously favoured by the opening of Porto’s airport new terminal that greatly powered low-cost companies and the licensing for the rehabilitation of houses for...
Novel polymeric nanoparticles as nanofertilisers for alkaline iron‐deficient co...
Pinho, Simão; Santos, Carla; Moniz, Tânia; Granja, Andreia; Sarraguça, Mafalda; Reis, Salette; Rangel, Maria; Vasconcelos, MartaBackground and aims Iron deficiency chlorosis (IDC) is a nutritional disorder impacting plants and is prevalent in calcareous alkaline soils, correspond- ing to 30% of the world’s arable land. IDC compro- mises iron uptake in crops such as soybean (Glycine max). To improve the effect of iron fertilisers, we sought to develop a nanotechnology-based interven- tion using polymeric nanoparticles (NPs) loaded with F...
Synergistic effect of nickel and melatonin on drought tolerance in pea (pisum s...
Spoloar, Bruna Oliveira Reinheimer; Silva, Marta Nunes da; Geraldo, Rafaela; Moro, Adriana Lima; Vasconcelos, MartaIntroduction: The intensification of drought events due to climate change threatens global food security. Pea (Pisum sativum) is a key legume for sustainable agriculture, as it fixes nitrogen, improves soil fertility, and has high nutritional value. However, it is highly sensitive to water stress. Nickel (Ni) is an essential micronutrient in nitrogen metabolism, while melatonin (MEL) regulates oxidative stress....
Integrating ecosystem services provided by legumes in agricultural life cycle a...
Cimarelli, Stefano; Goglio, Pietro; Serpa, Dalila; Quagliolo, Carlotta; Dorca-Preda, Teodora; Sadhu, Abbigel; Rai, Kamala; Roebeling, PeterAgricultural production is endangering agroecosystems health and functioning, compromising the delivery of many ecosystem services (ES) to prioritize provisioning. Legumes’ inclusion in cropping systems appears as a promising solution towards the ecological intensification of agriculture in Europe, providing a multiplicity of ES. Agricultural Life Cycle Assessment (LCA) does not explicitly assess ES; however, t...
Characteristics of lower-limb peripheral arterial disease in women
Vasconcelos, Marta; Costa, Patrício; Alonso, Rita; Ferreira, JoanaINTRODUCTION: Peripheral Arterial Disease (PAD) affects more than 200 million people. Its estimated prevalence in women ranges from 3% to 29%. Asymptomatic PAD is more common in women than in men. However, when symptomatic, females present a more complex disease, severe critical limb-threatening ischemia (CLTI), and worse outcomes. This study aims to characterize PAD in hospitalized women, evaluating risk facto...
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...
Predicting iron deficiency and oxidative stress in glycine max through Fourier ...
Santos, Carla S.; Sousa, Clara; Bagheri, Maryam; Pinho, Simão; Vasconcelos, MartaAims: The excessive use of fertilizers is a problem in current agricultural systems, and sustainable farming practices, including precision agriculture, demand the use of new technologies to manage plant stress at an early stage. To sustainably manage iron (Fe) fertilization in agricultural fields, it is urgent to develop early detection methods for Fe deficiency, and linked oxidative stress, in plant leaves. H...
Combined effect of elevated CO2 and Fe deficiency on common bean metabolism and...
Deuchande, Teresa; Vasconcelos, MartaAims: Elevated atmospheric CO2 (eCO2) and restricted iron (Fe) supply are known to impact plant growth and nutritional quality of food crops. However, studies aimed at understanding how eCO2 will interact with Fe deficiency are scarce. Changes in the nutritional status of the common bean (Phaseolus vulgaris L.) may significantly impact the nutritional status of populations that rely heavily on this crop. Method...
