Edible coatings with polysaccharides and bioactive compounds from exhausted oli...
Martins, V.; Lopes, A.; Pintado, M.; Morais, R. M. S. C.; Morais, A. M. M. B.Introduction: Exhausted or delipidified olive oil pomace (EOP) is a by-product generated from the olive pomace after air drying and hexane extraction of residual oil [1]. This by-product is rich in phenolic compounds, such as hydroxytyrosol, tyrosol and catechol, with associated properties: antioxidant, antimicrobial, anti- inflammatory, anti-diabetic, anti-carcinogenic and anti-HIV [1, 2]. Coatings and films a...
Alga Fucus sp. extracts to produce edible films
Martins, V.; Machado, M.; Costa, E.; Gomes, A. M.; Poças, F.; Pintado, M.; Morais, R. M. S. C.; Morais, A. M. M. B.Introduction: Macroalgae are a good source of nutrients, such as carbohydrates (dietary fiber and polysaccharides), proteins, lipids and minerals [1,2]. Fucus sp. is composed of valuable bioactive compounds, such as fucoxanthin, vitamins, water-soluble (vitamin C and of complex B) and fat-soluble (vitamins A, D, E and K), phenolic compounds, lipids (MUFA and PUFA), and polysaccharides (fucoidans and alginic aci...
Characterization of alga Fucus sp. extracts and residues and their application ...
Martins, V.; Coelho, M.; Machado, M.; Costa, E.; Gomes, A. M.; Poças, F.; Pintado, M.; Morais, R. M. S. C.; Morais, A. M. M. B.Introduction: Macroalgae are a good source of nutrients, such as carbohydrates (dietary fiber and polysaccharides), proteins, lipids and minerals, and they are sustainable, because they do not compete with food crops for arable land and potable water [1,2]. Fucus sp. is composed of valuable bioactive compounds, such as fucoxanthin, vitamins, water-soluble vitamins (vitamin C and of complex B) and fat-soluble vi...
A low-cost sensor system installed in buses to monitor air quality in cities
Correia, C.; Martins, V.; Matroca, B.; Santana, P.; Mariano, P.; Almeida, A.; Almeida, S.M.Air pollution is an important source of morbidity and mortality. It is essential to understand to what levels of air pollution citizens are exposed, especially in urban areas. Low-cost sensors are an easy-to-use option to obtain real-time air quality (AQ) data, provided that they go through specific quality control procedures. This paper evaluates the reliability of the ExpoLIS system. This system is composed o...
Screening methodologies to extract polyphenols from olive oil pomace
Martins, V.; Ribeiro, T. B.; Pintado, M.; Morais, R.M.C.S.; Morais, A.M.M.B.Olive oil is a product from the fruits of the plant Olea europaea L. About two million ton of olive oil are produced annually, whereas Spain, Italy and Greece are the major producers. Its production worldwide causes 30 million m3 of olive mill waste each year 1, which consist of olive oil pomace and olive wastewater. Following the goals of the ONU agenda for 2030, under the topic of circular economy that includ...
Reliability and validity of the Chester step test in patients with interstitial...
Alves, A.; Oliveira, A.; Ferreira, P. G.; Martins, V.; Marques, A.The Chester Step Test (CST) is a simple and inexpensive field test, which requires minimal physical space to assess exercise capacity. Such characteristics make the CST suitable to be used in different settings, however, its measurement properties in patients with interstitial lung diseases (ILD) are unknown. A cross-sectional study was conducted in patients with ILD. First, a CST-1 and a 6-minute walk test (6M...
Presence of extra-pulmonary treatable traits in people with COPD increases the ...
Souto-Miranda, S.; Rocha, V.; Mendes, M. A.; Simão, P.; Martins, V.; Spruit, M. A.; Marques, A.Introduction: Evidence suggests that people with chronic obstructive pulmonary disease (COPD) who have worse clinical status (e.g., higher symptom burden) at baseline respond better to pulmonary rehabilitation. Identification of treatable traits in this population might help to better distinguish responders from non-responders, which could aid optimisation of the intervention in the future. This study aimed to ...
Functional status and impact of the disease in people with COPD according to sy...
Machado, A. F.; Antão, J.; Souto-Miranda, S.; Rocha, V.; Alves, A.; Cruz, J.; Jácome, C.; Mendes, M. A.; Martins, V.; Simão, P.; Burtin, C.; Marques, A.Background: COPD is a heterogeneous disease. Better understanding of its trajectory, especially considering symptoms level, may help improving disease management. We described the evolution of functional status and impact of the disease in people with COPD according to symptoms level. Methods: People with COPD were assessed monthly for 6 months. Participants were grouped by the Global Initiative for Chronic Obs...
Are indoor and outdoor opportunities for physical activity related to active be...
Hipólino, N.; Flora, S.; Gordo, J.; Pimenta, S.; Morais, N.; Silva, C. G.; Ribeiro, J.; Silva, F.; Oliveira, A.; Brites-Pereira, M.; Carreira, B. P.Introduction: Persistent respiratory symptoms at rest and during exertion (e.g., dyspnea, fatigue) play a role on the low physical activity (PA) levels found in people with chronic obstructive pulmonary disease (COPD), but other factors may also be involved. Environmental factors have been shown to impact PA levels in other patient populations, but evidence regarding people with COPD is still scarce. Investigat...
Cut-off points of the 1-minute sit-to-stand test to detect functional impairmen...
Dias, C.; Machado, A.; Mendes, M.; Ferreira, D.; Martins, V.; Simão, P.; Marques, A.Introduction: Functional status is a key outcome in people with chronic obstructive pulmonary disease (COPD) and can be defined as an individual’s ability to perform normal daily activities required to meet basic needs, fulfill usual roles, and maintain health and well-being. The 1-minute sit-to-stand test (1-min STS) is a wellestablished measure to assess functional status in people with COPD that can be used ...
