Healthy and safe environments across occupational and environmental contexts: A...
Carvalhais, Carlos; Pereira, Cristiana C.; Santos, JoanaAccording to the World Health Organization (WHO), “good health depends on clean air, a stable climate, and a preserved natural environment, as well as access to adequate water, sanitation, and hygiene. It also requires protection from harmful radiation, unsafe chemical management, and unhealthy working conditions. A healthy environment could prevent nearly a quarter of the global disease burden”. In line with t...
NADES-in-Oil Emulsions Enriched with Essential Oils for Cosmetic Application
Freitas, David; Rocha, Diana; Santos, Joana; Noro, Jennifer Martins; Tavares, Tânia D.; Teixeira, Marta O.; Araújo, Daniela; Castro, Joana Isabel ReisThis research aims to explore the potential benefits of natural deep eutectic solvents (NADES) in formulating translucent NADES-in-oil emulsions (TEs) containing essential oils (EOs) for cosmetic applications. The TEs investigated in this study are based on previous formulations, consisting of 50 wt.% egg phosphatidylcholine (EPC), 20 wt.% ethanol, 20 wt.% olive oil (OlO), thyme oil (TO), or oregano oil (OrO), ...
Laccase-catalyzed polymerized natural bioactives for enhanced mushroom tyrosina...
Costa, Diana; Rocha, Diana; Santos, Joana; Noro, Jennifer Martins; Ribeiro, Artur; Silva, CarlaSkin hyperpigmentation disorders, such as melasma, are linked to excessive melanin production, primarily regulated by the enzyme tyrosinase (TYR). While current inhibitors like kojic acid (KA) are effective, they often cause adverse side effects, driving the search for safer andnatural alternatives. This study evaluated the TYR inhibitory potential of bioactive-rich extracts from acorn, cocoa, cork, and eucalyp...
Exploring canine mast cell tumors: An investigation into demographic characteri...
Catarino, José; Pinello, Katia; Niza-Ribeiro, João; Santos, Joana; Payan-Carreira, Rita; Reis, Joana; Faísca, PedroMast cell tumors (MCT) are among the most common neoplasia in dogs, representing up to 21 % of skin tumors. However, etiology and risk factors for its development remain unclear. This study aimed to reduce this knowledge gap by comprehensively analyzing 905 MCT cases diagnosed in Portugal between 2019 and 2021, using descriptive and inferential analyses. Most tumors affected the skin, with 69.9 % and 21.2 % cla...
Enzymatic degradation of ochratoxin A: the role of ultra-pure water
Santos, Joana; Oliveira, Constança; Teixeira, Filipe; Venâncio, Armando; Silva, C.Ochratoxin A (OTA) is a toxic mycotoxin, making its removal from food essential for public health. This study examines OTA degradation by porcine pancreatic lipase (PPL) in ultra-pure water versus buffer systems through in vitro assays and molecular modeling. The results show that PPL fully degrades OTA in ultra-pure water within 7 h at 44 °C, whereas only partial degradation occurs in phosphate buffer. After 4...
Prevalence of the use of dosimeters for ionizing radiation from fluoroscopy − a...
Videira, Sara; Rodrigues, Matilde; Santos, Joana; Guedes, Joana; Martins, João; Silva, Manuela Vieira da; Vieira da Silva, Manuela; Rodrigues, MatildeThis study aims to assess the prevalence of individual dosimeter use among workers exposed to ionizing radiation during fluoroscopy-guided procedures. Additionally, factors contributing to its use were identified. Studies were identified through searches in five databases on 13 April 2024. Additionally, snowballing techniques were employed. The review followed PRISMA guidelines and the CoCoPop model. A narrativ...
Analysis of the carbon footprint of a textile company for the automotive industry
Silva, Beatriz; Malheiro, David; Júnior, Dinis; Nunes, Francisca; Santos, Joana; Guimarães, Liliana; Socorro, Maria; Carvalho, Mariana; Silva, MarianaThis study aims to develop a process to calculate the carbon footprint of a company in the textile sector for the automotive industry, thus addressing a research gap identified in this sector. Based on a structured calculation model, the project aspires to innovate by quantifying not only the greenhouse gas emissions at different stages of the company’s operations, including those generated by the consumed elec...
Nano versus bulk: Evaluating the toxicity of lanthanum, yttrium, and cerium oxi...
Santos, Joana; Neca, Inês; Capitão, Ana; Nogueira, João; Santos, José A. S.; Pinto, Edgar; Barreto, Angela; Silva, Ana L. Daniel da; Maria, Vera L.Considering the increase in demand for rare earth elements (REEs) and their accumulation in soil ecosystems, it is crucial to understand their toxicity. However, the impact of lanthanum, yttrium and cerium oxides (La2O3, Y2O3 and CeO2, respectively) on soil organisms remains insufficiently studied. This study aims to unravel the effects of La2O3, Y2O3 and CeO2 nanoparticles (NPs) and their corresponding bulk fo...
A practical case of mentoring in higher education at a health school
Saúde, Miguel; Ferraz, Ricardo; Silva, Vítor; Barreto, João; Portugal, Paula; Santos, Joana; Vieira, Mónica; Vieira, Mónica; Santos, JoanaThe rapid advancement of Generative Artificial Intelligence (AI) tools is reshaping higher education, particularly in creative fields such as design, multimedia, and audiovisuals. Students increasingly seek faster solutions for academic challenges, often relying on AI-generated content rather than engaging in research, critical analysis, and validation through credible sources or instructors. This tendency weak...
