Killer yeasts as sustainable solutions for foodborne pathogens control
Serra, Patrícia; Araújo, Daniela Eira; Gomes, Fernanda Isabel Antunes; Almeida Aguiar, Cristina; Silva, Sónia Carina[Excerpt] lntroduction Killer yeasts produce toxins that inhibit other microorganisms, providing a competitive advantage in a wide range of environments, from natural ecosystems to industrial applications. Their potential as natural biocontrol agents has been explored, particularly in food systems, where the control of spoilage organisms and foodborne pathogens is essential to guarantee safety and quality.[...]
Durable and breathable ZnO/graphene-coated fabrics for enhanced BQR protection
Ferreira, Tânia; Vale, A. Catarina; Gonçalves, Afonso; Pinto, Alexandra C.; Sousa, Diana; Guimarães, Humberto; Moreira, Inês P.; Silva, CarlosThis work developed a new strategy to create active protection against chemical, biological, radiological and nuclear (CBRN) threats, based on polyurethane-based coatings for outer (water and oil-repellency) and inner (CBRN protection) functionalization of fabric. The internal coatings were functionalized with varying concentrations of zinc oxide nanoparticles (ZnO) and/or graphene nanoplatelets (Gf) and carefu...
Upcycling fishing net waste and metal oxide from electroplating waste into alga...
Barros, Daniel; Nobre, Luís; Antunes, Joana; Bessa, João; Cunha, Fernando Eduardo Macedo; Mota, Carlos; Gomes, Fernanda Isabel AntunesPlastic waste, especially discarded fishing nets, and electroplating sludges pose significant environmental challenges, impacting marine ecosystems and contributing to pollution. In alga cultivation, invasive microorganisms often hinder growth, necessitating strategies to combat these issues. This study aimed to develop recycled substrates for alga cultivation by repurposing fishing nets and enhancing their sur...
Uso de modelo Ex vivo para simulação de colonização de lesões por pressão por b...
Pinto, Alexandra Catarina Gonçalves; Antunes, Joana; Henriques, Mariana; Fangueiro, Raúl; Salgueiro-Oliveira, Anabela; Gomes, Fernanda Isabel AntunesOs biofilmes polimicrobianos têm sido alvo de crescente investigação devido ao seu papel como um dos grandes desafios de saúde pública, especialmente em contexto de feridas crónicas. As lesões por pressão (LP) são lesões localizadas na pele e nos tecidos moles causadas por pressão, cisalhamento ou atrito não aliviados1,2e ocorrem principalmente em pessoas com mobilidade reduzida3. As regiões mais propícias à oc...
Glycyrrhiza glabra hydroethanolic extract and manuka honey alone and in combina...
Gomes, Fernanda Isabel Antunes; Dias, Maria Inês; Rodrigues, Maria Elisa Costa; Barros, Lillian; Henriques, MarianaBackground The natural tendency of polymicrobial infections and co-habitation of bacteria and Candida are currently well-recognized and reported as highly fatal. This kind of interaction is usually associated with drug tolerance, infection relapse, persistence and high mortality. The interest in natural products has emerged and their potential applicability as therapeutic strategies is being constantly explored...
Development of smart clothing to prevent pressure injuries in bedridden persons...
Rêgo, Anderson da Silva; Furtado, Guilherme Eustáquio; Bernardes, Rafael A.; Santos-Costa, Paulo; Dias, Rosana A.; Alves, Filipe S.; Ainla, AlarPressure injuries (PIs) are a major public health problem and can be used as quality-of-care indicators. An incipient development in the field of medical devices takes the form of Smart Health Textiles, which can possess innovative properties such as thermoregulation, sensing, and antibacterial control. This protocol aims to describe the process for the development of a new type of smart clothing for individual...
Comparison of zinc oxide nanoparticle integration into non-woven fabrics using ...
Ferreira, Tânia; Vale, Ana Catarina; Pinto, Alexandra C.; Costa, Rita V.; Pais, Vânia; Sousa, Diana; Gomes, Fernanda Isabel Antunes; Pinto, GraçaThe development of advanced facemasks stands out as a paramount priority in enhancing healthcare preparedness. In this work, different polypropylene non-woven fabrics (NWF) were characterised regarding their structural, physicochemical and comfort-related properties. The selected NWF for the intermediate layer was functionalised with zinc oxide nanoparticles (ZnO NPs) 0.3 and 1.2wt% using three different method...
The influence of methods of functionalization, knitting structures, and washing...
Pinto, Alexandra Catarina; Henriques, Mariana; Gomes, Pedro; Cruz, Juliana; Gomes, Fernanda Isabel AntunesThe growing technology development and concern with health and hygiene have promoted the development of new functionalized textiles, such as those with antimicrobial properties. Thus, the main objective of this work was to evaluate the antibacterial activity and durability of silver-modified textiles functionalized by two different methods: fiber extrusion (functional fiber) and exhaustion (surface functionalit...
