Mushroom-derived polysaccharides as bioactive agents for skin regeneration: eva...
Fernandes, A.; Lopes, A.; Magalhães, R.; Oliveira, C.; Pintado, M.; Tavaria, F.Mushroom polysaccharides have emerged as promising bioactive agents for enhancing skin regeneration. This study evaluates three polysaccharide-rich fractions (SB, SC, RD) obtained by hot water and alkaline extractions from Coriolus versicolor, Pleurotus ostreatus, and Hericium erinaceus. Their potential to promote skin repair was investigated by analyzing effects on cell proliferation and migration, immune modu...
After all, Porphyria exists in Portugal! A three-year study
Ferreira, Filipa; Carmona, Célia; Lopes, A.; Ramos, S.; Nogueira, Célia; Pereira, Cristina; Pavão, C.; Oliveira, F.; Pimenta, R.; Brasão, L.Introduction: Porphyrias are a group of eight rare inherited disorders, each caused by a defect in a specific enzymatic step of heme biosynthesis. These disorders are multisystemic, with variable symptoms, and represent a major burden for patients and families, with disabling chronic symptoms scattered with life-threatening acute attacks. There are two main clinical types of porphyria: acute porphyria and cutan...
Ethylene removal by Ag-based ZSM-5 adsorbents for the preservation of climacter...
Ferreira, R.; Lopes, H.; Lourenço, J. P.; Silva, J. M.; João, I. M.; Ribeiro, M. F.; Fernandes, A.Ethylene removal is crucial for fruits and vegetables preservation because even a very low concentration (<0.1ppm) can induce ripening during storage and transportation. Ag+ exchanged ZSM-5 zeolites were investigated as adsorbents for the efficient removal of ethylene. Two ZSM-5 materials (Si/Al ratios of 15 and 40), with different amounts of Ag (up to 6 % by weight) and two compensating cations, Na+ and H+, we...
Intelligent sensors in assistive systems for deaf people: A comprehensive review
Soares, C. C. S.; Silva, L. A.; Fernandes, A.; Villarrubia González, G.; Leithardt, V. R. Q.; Parreira, W. D.This research aims to conduct a systematic literature review (SLR) on intelligent sensors and the Internet of Things (IoT) in assistive devices for the deaf and hard of hearing. This study analyzes the current state and promise of intelligent sensors in improving the daily lives of those with hearing impairments, addressing the critical need for improved communication and environmental interaction. We investiga...
Mapping and integrating security and risk standards: A systematic literature re...
Fernandes, A.; Cruz, J.; Silva, M. M. da.; Pereira, R.Organizations are under increasing pressure to comply with various rules, standards, and policies in today’s regulatory environment. Compliance controls are put in place to avoid legal or regulatory violations, which could lead to severe penalties, loss of reputation, and financial damages. However, these controls may have similar scopes and objectives, resulting in duplicated work and unnecessary costs for the...
Fighting occupational risks among Portuguese wildland firefighters: looking at ...
Esteves, F.; Slezakova, K.; Madureira, J.; Vaz, J.; Fernandes, A.; Carmo, M.; Morais, S.; Teixeira, J. P.; Costa, S.Background: Evidence linking wildland firefighters’ occupational exposure and health outcomes is still limited. Cytogenetic endpoints have long been applied in the surveillance of human genotoxic exposures and early effects of genotoxic carcinogens. Therefore, it is of utmost importance to clarify the exposure-induced cytogenetic effects concerning wildland firefighters’ occupational exposure at different time ...
Detecting and developing new business opportunities in society 5.0 contexts: A ...
Çipi, A.; Fernandes, A.; Ferreira, F.; Ferreira, N.; Meidute-Kavaliauskiene, I.Rapid technological evolution has become a great challenge for businesses and societies due to the openness provided by new digital technologies, platforms, and infrastructure and to the impacts of these innovations on how people work and live. The concept of a super-smart society (i.e., Society 5.0) comprises a fresh way to apply these innovations, in which human beings contribute to adapting technologies to d...
Medicines and medication literacy: Social practices and use of information
Lopes, N.; Pegado, E.; Egreja, C.; Rodrigues, C. F.; Fernandes, A.This article discusses results from a sociological study on (i) the sources and use of information on medicines and/or supplements and (ii) the self-assessment of how informed participants were about the last medicine or supplement they purchased. It seeks to demonstrate the plurality of information sources (expert and lay) that individuals call upon—with which they build up their medication literacy—and their ...
Urinary biomonitoring in firefighters: baseline data of polycyclic aromatic hyd...
Barros, B.; Oliveira, M.; Paiva, M.; Fernandes, A.; Alves, S.; Vaz, J.; Esteves, F.; Slezakova, K.; Alves, M.J.; Madureira, J.; Pereira, M.C.Polycyclic aromatic hydrocarbons (PAHs) are among the most relevant pollutants in the firefighting context and urine the most straightforward and interesting matrix for biomonitoring. Recent studies have found elevated levels of PAH metabolites in firefighters in comparison to the general population. Since Portuguese firefighters are poorly characterized, the aim of this study was to determine the baseline data...
A systematic review of natural products for skin applications: targeting inflam...
Fernandes, A.; Rodrigues, P. M.; Pintado, M.; Tavaria, F. K.Background: Every day the skin is constantly exposed to several harmful factors that induce oxidative stress. When the cells are incapable to maintain the balance between antioxidant defenses and reactive oxygen species, the skin no longer can keep its integrity and homeostasis. Chronic inflammation, premature skin aging, tissue damage, and immunosuppression are possible consequences induced by sustained exposu...
