LC-ESI-UHR-QqTOF-MS/MS profiling and anti-inflammatory potential of the cultiva...
Zeghbib, Walid; Boudjouan, Fares; Carneiro, João; Oliveira, Ana L. S.; Sousa, Sérgio F.; Pintado, Manuela Estevez; Ourabah, Asma; Vasconcelos, VitorOpuntia plants are abundant but still underexplored edible resources of the Algerian region. This work chemically characterizes extracts of different parts of the fruit of the commercial Opuntia ficus-indica (L.) Mill. and the wild Opuntia stricta (Haw.) Haw. growing in Bejaia, and evaluates their anti-inflammatory potential through different cell and cell-free bioassays. The LC-ESI-UHR-QqTOF-MS/MS analysis ena...
Chaves thermal spring water impact on skin health: potential cosmetic application
Pinto-Ribeiro, Inês; Castro, Cláudia; Rocha, Pedro Emanuel; Carvalho, Maria João; Pintado, Ana; Mendes, Adélia; Pedrosa, Sílvia Santos; Capeto, PaulaSince ancient times, thermal spring water has been proven to be beneficial to the skin and to improving dermatologic disorders, explaining its incorporation into cosmetic formulations as an active ingredient. Chaves thermal spring water, from northern Portugal, has been used as a local spa since Roman times, and its customers are satisfied with its medicinal quality. Despite the lack of published evidence on it...
Fire-resistant bio-based polyurethane foams designed with two by-products deriv...
Capêto, Ana Paula; Amorim, Manuela; Sousa, Sérgio; Costa, Joana R.; Uribe, Braian; Guimarães, Ana Sofia; Pintado, Manuela; Oliveira, Ana L. S.There is a growing interest in replacing conventional fossil-based polymers and composites with waste-based materials and fillers for environmental sustainability. This study designed water-blown polyurethane rigid foams using two by-products from the Amyris fermentation process of producing β-farnesene. The distillation residue (FDR) served as the main polyol component in the foam’s formulation (PF), supplemen...
New natural and sustainable cosmetic preservative based on sugarcane straw extract
Carvalho, Maria João; Pedrosa, Sílvia Santos; Pintado, Manuela; Oliveira, Ana L. S.; Madureira, Ana RaquelPreservative ingredients in cosmetic formulations undertake a necessary role in the prevention of microbial contamination. In this field, there is an unmet need for natural, sustainable, and effective preservatives. Thus, the main goal of this work was to evaluate a sugarcane straw extract-based ingredient and investigate its potential as a preservative for cosmetic applications. Different ingredients were deve...
Building a greener future: advancing concrete production sustainability and the...
Capêto, Ana Paula; Jesus, Manuel; Uribe, Braian E. B.; Guimarães, Ana Sofia; Oliveira, Ana L. S.The integration of waste materials in extrudable cement mixtures has the potential to make the construction industry more sustainable by reducing carbon footprints and developing eco-friendly materials. This along with advancements in 3D concrete printing (3DCP) provides engineering and architectural benefits by reducing material waste and costs. In this paper, the impact of waste incorporation on properties of...
Anti-aging potential of a novel ingredient derived from sugarcane straw extract...
Carvalho, Maria João; Pedrosa, Sílvia Santos; Mendes, Adélia; Azevedo-Silva, João; Fernandes, João; Pintado, Manuela; Oliveira, Ana L. S.Natural and sustainable anti-aging ingredients have gained attention from the cosmetic industry. This study evaluated the anti-aging potential of a sugarcane straw extract-based (SSE) cosmetic ingredient. First, cytotoxicity tests were assessed in keratinocytes and fibroblast cell lines, and sensitization was carried out through the direct peptide reactivity assay. Subsequently, various anti-aging properties we...
Synthesis of thermoset elastomer from microbial oil derived from the fermentati...
Capeto, Ana Paula; Uribe, Braian Esneider Buitrago; Pintado, Manuela; Guimarães, Ana Sofia; Oliveira, Ana L. S.In the context of the 21st century, the integration of diverse perspectives within the circular economy framework, encompassing waste management, economic growth, and environmental sustainability, stands out as a paramount challenge. Addressing this challenge, an innovative avenue emerges through the application of microbial oil to replace traditional petroleum in the synthesis of essential commodity chemicals....

Lavandula pedunculata polyphenol-rich extracts obtained by conventional, MAE an...
Vilas-Boas, Ana A.; Goméz-García, Ricardo; Machado, Manuela; Nunes, Catarina; Ribeiro, Sónia; Nunes, João; Oliveira, Ana L. S.; Pintado, ManuelaNowadays, plant-based bioactive compounds (BCs) are a key focus of research, supporting sustainable food production and favored by consumers for their perceived safety and health advantages over synthetic options. Lavandula pedunculata (LP) is a Portuguese, native species relevant to the bioeconomy that can be useful as a source of natural BCs, mainly phenolic compounds. This study compared LP polyphenol-rich e...
