Mental Health of Higher Education Teachers at Work: Integrative literature review
Quadros Niza, Cristina; Ferreira, Rui; Marques, Maria; Gonçalves, AmadeuIntroduction: Occupational stress occurs due to poor working conditions, negatively affecting the mental health, skills and performance of higher education teachers. It has a significant effect on their quality of life, health and job satisfaction. Objective/s: To investigate the factors that interfere with the mental health of higher education teachers at work. Methods: An integrative literature review was car...
Unlocking the fatty acid and antioxidant profile of grape pomace: a systematic ...
Abreu, Teresa; Ferreira, Rui; Castilho, Paula C.; Câmara, José S.; Teixeira, Juan; Perestrelo, Rosa; De Abreu Abreu, Maria Teresa; Ferreira, Rui<jats:p>Grape pomace (GP), the main by-product of the wine industry, represents a valuable source of bioactive metabolites with significant potential for valorization in the context of sustainable bioresource management. This study systematically characterizes the fatty acid methyl ester (FAME) profile, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activities (DPPH, ABTS, ORAC) of...
Free amino acids accelerate the time‐dependent inactivation of rat liver nucleo...
Romero, Ana; Cumplido-Laso, Guadalupe; Fernández, Ascensión; Moreno, Javier; Canales, José; Ferreira, Rui; López‐Gómez, Juan; Meireles Ribeiro, JoãoNucleotide-pyrophosphatases/phosphodiesterases (NPP/PDE) are membrane or secreted Zn2+-metallohydrolases of nucleoside-5 ́-monophosphate derivatives. They hydrolyze, for instance, ATP and 4-nitrophenyl-dTMP, and belong to the ecto-nucleotide pyrophosphatase/phosphodiesterase (ENPP) family that contains seven members (ENPP1-ENPP7). Earlier we had shown that an NPP/PDE activity solubilized and partially purified ...
Merging standardization and adaptability for efficient modular construction sol...
Branco, Jorge M.; Tenório, Marina; Alves, Rita; Sousa, Filipe; Ferreira, Rui; Meireis, Cláudio; Leitão, Dinis; Fontes, André; Silva, Sandra MonteiroModular timber construction represents a groundbreaking and eco-friendly advancement in the building sector. The constant evolution of construction methods, technologies and requirements, the concern of those who live architecture and, more recently, the climate crisis and social pressures, have made timber a viable alternative to conventional materials such as concrete, masonry and steel. The lightweight and v...
Effects of adding walnut shell to coir-based substrates on yield and quality of...
Machado, R.M.A; Alves-Pereira, Isabel; Grilo, Ana; Ferreira, RuiEnhancing the sustainability of growing media is an important objective in soilless vegetable cultivation. Here, we evaluated the potential of pine bark to replace perlite in coir-based substrates for lettuce (Lactuca sativa L. cv. ‘Godzilla’) cultivation. The experiment followed a factorial design with two coir-based substrate blends—one amended with perlite and the other with pine bark—and two nutrient soluti...
Acute physiological response to three different isometric exercises on hemodyna...
Ferreira, Rui; Abrantes, CatarinaAccording to the literature, exercise sessions for the population with hypertension are usually combined with cardiovascular exercise followed by isometric muscle strength exercise. So, this study aims to evaluate the acute effect of 3 strength exercises focusing on isometric contractions on Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), Mean Blood Pressure (MAP) and heart rate (HR). A total of ...
Strategic and multidisciplinary analysis of increasing airport capacity in the ...
Ferreira, Rui; Araujo, Marco; Tereso, Anabela Pereira; Novais, PauloThe selection for the location of complex infrastructures, such as airports, constitutes a challenging decision-making process due to its potential socioeconomic impacts alongside other complex factors that impact the decision process. Within this scope, this article proposes a Multi-Criteria Decision-Making (MCDM) framework to analyze and evaluate potential airport locations to select the most suitable one amo...
Plant-derived terpenoids: a plethora of bioactive compounds with several health...
Câmara, José S.; Perestrelo, Rosa; Ferreira, Rui; Berenguer, Cristina V.; Pereira, Jorge A. M.; Castilho, Paula C.; Câmara, José; Perestrelo, Rosa<jats:p>Terpenoids are a large class of natural secondary plant metabolites which are highly diverse in structure, formed from isoprene units (C-5), associated with a wide range of biological properties, including antioxidant, antimicrobial, anti-inflammatory, antiallergic, anticancer, antimetastatic, antiangiogenesis, and apoptosis induction, and are considered for potential application in the food, cosmetics,...
Effect of reusing coir-based substrates with municipal compost and biochar on g...
Machado, Rui M.A.; Alves-Pereira, Isabel; Alves, Inês; Ferreira, RuiThe aim of this research was to evaluate the influence of reusing, coir-based substrates with municipal organic compost or biochar on growth and phytochemical accumulation in lettuce. The experiment included five substrates: coir (new) and four mixtures: coir: biochar: perlite, coir: compost: perlite, coir: biochar: pine bark, and coir: compost: pine bark. All of the mixtures had already been used to grow trans...
Asymptomatic chronic red eye: a surgical technique case report
Matos, Diogo Bernardo; Guerra, Paulo; José, Patrícia; Ferreira, Rui; Quintas, Ana; Marques-Neves, CarlosIntroduction and importance: Ocular Surface Squamous-cell Neoplasia (OSSN) is an infrequent diagnosis whose clinical suspicion assumes great importance and should not be overlooked. The following case-report aims to describe the diagnosis and treatment of a patient with OSSN whose complaints were mild in comparison to the severity of the disease. The chosen surgical technique was paramount for a disease-free ou...
