Bioactive metabolites from algae: occurrence, extraction techniques, functional...
Pereira, Cláudia S.G.P.; Carpena, M.; Barreira, João C.M.; Silva, Cristiana F.C.; Prieto Lage, Miguel A.; Oliveira, BeatrizThis review critically summarizes the major algal-derived bioactive compounds, including phenolics compounds (e.g., phlorotannins, bromophenols, phenolic acids), sterols (e.g., fucosterol, beta-sitosterol), and polysaccharides (e. g., carrageenan, fucoidan, ulvan), as well as key pigments such as astaxanthin, beta-carotene, lutein, violaxanthin, zeaxanthin, and chlorophylls. In addition, state-of-the-art extrac...
Translation and Validation of the Portuguese Version of European School for Int...
Haider, Haúla F.; Fernandes, Ana Solange; Aguiar, Ana Filipa; Oliveira, Beatriz; Peixoto, Iris; Antunes, Marília; Hoare, Derek James; Caria, HelenaObjective: Several questionnaires for the diagnosis and characterization of tinnitus are available in English but there is a need for Portuguese standardized questionnaires for use in research and in clinic. The goals of this study were to translate and culturally adapt the ESIT-SQ (European School for Interdisciplinary Tinnitus Research Screening Questionnaire) to Portuguese, and to validate the questionnaire ...
Investigating bioactive compounds in apple pomace: Potential to develop high ad...
Pascoalino, Liege; Finimundy, Tiane C.; Pires, Tânia C.S.P.; Pereira, Carla; Barros, Lillian; Ferreira, Isabel C.F.R.; Oliveira, BeatrizThis study investigates bioactive compounds in apple pomace (AP) obtained from Malus domestica varieties Granny Smith and Cripps Pink, emphasizing its potential for developing high-added-value products from industrial surplus. Regarding its chemical characterization, AP stood out for its high concentration of dietary fibers (7.1g/100g fw), polyunsaturated fatty acids (linoleic and oleic acids), α-tocopherol (0....
Closing the loop: exploring apple pomace as a source of bioactive compounds in ...
Pascoalino, Liege; Barros, Lillian; Barreira, João C.M.; Oliveira, Beatriz; Reis, Filipa S.Apple pomace (AP), the common designation of bio-residues generated during apple processing, holds a vast potential for alternative added-value solutions, particularly by applying new sustainable technologies in the food sector. This review provides an overview of the scientific validation of AP as a suitable source of starting materials for different competitive applications, compatible with circular economy g...
Scoping Review on Management of Nephrostomy – and Double J-Stent – Associated I...
Oliveira, Beatriz; Magalhães, Marta; Vinagre, Nuno; Teves, Frederico; Fraga, AvelinoCatheter-associated urinary tract infections (CA-UTIs) refer to infections related to indwelling urinary catheters and are the main cause of hospital-acquired urinary tract infections. Most literature, including the European Urological Association (EAU) Urological Infections Guidelines, defines CA-UTIs as infections specifically associated with urethral catheters, excluding catheter-associated infections relate...
Valorisation of pumpkin by-products: Chemical composition and bioactive propert...
Leichtweis, Maria G.; Molina, Adriana K.; Dias, Maria Inês; Calhelha, Ricardo C.; Pires, Tânia C.S.P.; Pavli, Ourania; Oliveira, BeatrizThis study evaluated the fruit by-products (peels, seeds, and fibrous strands) from 11 pumpkin genotypes cultivated in Greece aiming to valorize them as natural sources of bioactive compounds. Five compounds, including ( )-epicatechin and chicoric acid isomers, were identified in peels, while seeds and fibrous strands mainly contained ( )-epicatechin. Organic acids and tocopherols varied significantly among gen...
Fostering a framework for secure data transfer from IoT devices to cloud
Oliveira, Beatriz; Alves, Rui; Pedrosa, TiagoThe Internet of Things (IoT) has indeed introduced a new era of connectivity and data-driven insights, profoundly altering everyday activities execution. The data collected by IoT devices, ranging from simple sensors to sophisticated systems integrated within urban infrastructure, gather and transmit data on a large scale, supporting a wide spectrum of applications including individual health metrics, home ener...
Innovative Learning in Undergraduate Medical Teaching: Perspective Based on Thi...
Rendas, António; Neuparth, Nuno; Carreiro-Martins, Pedro; Dores, Hélder; Oliveira, Beatriz; Costa, Teresa; Rosado-Pinto, Patrícia; Fonseca, MartaWe reviewed an innovative project in undergraduate medical education, which used problem-based learning and concept maps in pathophysiology teaching. We analyzed publications starting in 1995 and until 2024, to identify factors contributing to its continuity and impact, nationally and internationally.Problem-based learning was based on the methodology developed by Howard Barrows, a founder of the method. In 199...
Compositional and Bioactive Differentiation of Opuntia spp. Fruit Varieties by ...
Espírito Santo, Liliana; Pereira, Cláudia S.G.P.; Costa, Anabela S.G.; Almeida, Agostinho; Barreira, João C.M.; Oliveira, Beatriz; Vinha, Ana F.The nutritional, mineral, and bioactive profiles of four Opuntia fruit varieties-Opuntia robusta red variety (OR-RV) and three Opuntia ficus-indica varieties (red, yellow, and green: OFI-RV, OFI-YV, and OFI-GV, respectively)-were characterized to assess their compositional diversity and potential discriminant markers. Standard analytical procedures were applied to determine proximate composition, individual sug...
