Comparison of DNA barcoding and metabarcoding approaches for the authentication...
Pinto, M. Alice; Santos, Joana; Quaresma, Andreia; Honrado, Mónica; Rufino, José; Amaral, Joana S.The authentication of commercial herbal products such as herbal teas and infusions is essential to ensure consumer safety and product integrity. In this study, 100 commercial herbal infusions, including 94 single-species products and six polyherbal formulations, were analysed using DNA barcoding (matK and rbcL) and ITS2 metabarcoding. Moreover, the performance of two custom reference databases (NCBI and BOLD) w...
Bioactive and phenolic profiles in Pinus pinaster Bark : a comparative study of...
Barros, Diana; Alonso-Esteban, José Ignacio; Finimundy, Tiane C.; Pereira, Carla; Vaz, Josiana A.; Pereira-Pinto, Ricardo; Fernandes, ÉliaThis study conducted a comprehensive comparison of two green extraction methods, microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE), for recovering bioactive phenolic compounds from Pinus pinaster bark. The goal was to valorize timber industry waste and enhance the value of by-products through the development of eco-friendly processes to extract phenolic compounds from Pinus pinaster A...
Occupational exposure to solar ultraviolet radiation: A systematic review of pr...
Rocha, Ricardo; Santos, Joana; Baptista, João Santos; Guedes, Joana; Carvalhais, Carlos; Alberto Alves Carvalhais, Carlos; Santos, JoanaSolar ultraviolet radiation (UVR) is classified as a Group 1 carcinogen and poses a significant occupational hazard to outdoor workers. Despite preventive guidelines, adherence to protective measures remains inconsistent. This systematic review identified the protective measures adopted by healthy outdoor workers and assessed their adherence to and the effectiveness of these measures. Following the PRISMA 2020 ...
Green synthesis of gold nanoparticles using the seaweed Fucus spiralis and thei...
Abreu, João; Ribeiro, Joana; Rocha, Verónica; Fernandes, Mário; Ferreira, Inês; Santos, Joana; Sárria Pereira de Passos, Marisa; Silva, C.The increasing prevalence of neurodegenerative diseases such as Alzheimer's disease (AD) underscores the need for effective therapeutic strategies. Nanotechnology can provide new tools to counteract neurotoxicity, namely by improving bioavailability of therapeutic molecules in the brain. Brown seaweeds, such as Fucus spiralis (FS), are rich in bioactive compounds with antioxidant, anti-inflammatory, cytoprotect...
A systematic review of the health effects of occupational exposure to ultraviol...
Rocha, Ricardo; Guedes, Joana; Santos, Joana; Carvalhais, Carlos; Alberto Alves Carvalhais, Carlos; Santos, JoanaOutdoor workers face significant health risks from prolonged exposure to solar ultraviolet radiation (UVR), which can lead to serious conditions such as skin cancer and cataracts, while also offering some potential benefits like reduced risks of certain cancers. This systematic review synthesizes findings from 16 studies, revealing a clear association between occupational solar UVR exposure and adverse health e...
Avoiding anthropomorphic drift in ‘One Biology’ and ‘One Welfare’
Mata, Fernando; Jesus, Meirielly; Santos, JoanaIntegrative frameworks such as ‘One Welfare’ and ‘One Biology’ address the interconnectedness of animal welfare, human wellbeing, and environmental conditions by emphasising systemic interactions and shared biological mechanisms across species. Although grounded in scientific evidence, these approaches risk conceptual anthropomorphisation, whereby human-centred assumptions, emotional narratives, or cultural nor...
Microalgae-derived biopolymers: An ecological approach to reducing polylactic a...
Machado, Gabriela de O.; Assis, Marília L. de; Reis, Matheus F. de C.; Alexandre, Marcela A. da S.; Arruda, Tarsila R.; Pereira, Alexia S. A. de P.The growing demand for sustainable materials and the valorization of waste streams have intensified research on wastewater biorefineries and bioplastics. Within this framework, this study aims to develop and characterize poly (lactic acid) (PLA)-based films partially substituted with microalgae biomass derived from wastewater treatment at different concentrations (PLA-MA: 0, 10, 20, 30, 40, and 50%). The films ...
Application of probiotic bacteria in active packaging for the food industry: Re...
Oliveira, Juniel Marques de; Jesus, Meirielly; Santos, Jairo Neves de Jesus; Mata, Fernando; Dehghani, Sepehrdad; Santos, JoanaThe incorporation of probiotic bacteria into active packaging systems represents an innovative strategy to enhance food preservation while delivering health benefits to consumers. This review discusses the selection criteria for probiotic strains focusing on their resistance to environmental stressors, antimicrobial activity, and viability in different food matrices and their integration into edible films and c...
What do europeans expect from farmers? An empirical analysis of citizens’ prior...
Mata, Fernando; Campos, Susana; Jesus, Meirielly; Santos, JoanaThis study investigates European citizens’ perspectives on farmers’ roles, highlighting gender, age, education, political orientation, community size, social class, and attitudes towards the EU. This study was developed using 21,002 interviews with European Citizens from all 27 EU countries. A quantitative data analysis methodology was used from the European Eurobarometer 97.1 survey. Seven models were formulat...
Sustainable dyeing and functionalization of knitted cotton fabrics with algae e...
Oliveira, Helena S.; Santos, Joana; Ferreira, Tânia; Ribeiro, Artur; Silva, C.; Antunes, Joana C.; Bessa, João; Oliveira, Luís Miguel; Fangueiro, RaúlAlgae extracts have emerged as a sustainable and eco-friendly alternative to synthetic dyes and functional additives in the textile industry, particularly for dyeing and functionalizing of cotton fabrics. Herein, two types of water-soluble algae extracts from Arthrospira platensis and Porphyridium cruentum were characterized in terms of thermal, structural, and functional properties and used as dye and/or funct...
