Exploring the Impact of Ultrasound-Assisted Extraction on the Phytochemical Com...
Gouvinhas, Irene; Saavedra, Maria José; Alves, Maria José; Garcia, JulianaThe health benefits of Tamus communis fruits have been associated with their high phenolic content, which comprises several flavonoids. However, the extraction methods might significantly impact these valuable compounds' bioactivity. Therefore, the current study assesses how different extraction techniques affect T. communis extracts' antioxidant, anti-aging, antimicrobial, cytotoxic, anti-inflammatory, and phe...
Unlocking Nature’s Anti-Aging Secrets: The Potential of Natural Mineral Waters ...
Gama, Ana Rita; Gomes, Carolina P.; Caetano, Cátia; Oliveira, Ana Sofia; Rolo, Joana; Barros, Lillian; Plasencia, Paula; Garcia, JulianaSkin aging is influenced by intrinsic and extrinsic factors, leading to structural changes in the skin. Current anti-aging cosmetic trends emphasize innovative natural ingredients, including plant extracts, thermal waters, and botanical hydrolats. This work aims to develop six natural anti-aging cosmetics (two serums, two day creams, and two night creams) with innovative and non-irritating profiles. The rationa...
Multidrug-Resistant Escherichia coli Accumulated by Freshwater Bivalves: An Und...
Martins, Joana; Gonçalves, Ana; Fernandes, Conceição; Cabecinha, Edna; Monteiro, Sandra Mariza; Guedes, Hugo; Almeida, Gonçalo; Garcia, JulianaAs bioindicators, freshwater bivalves are crucial for the assessment of the contamination impact on different levels of biological integration. Escherichia coli is used as a bioindicator of water fecal contamination, representing a critical global concern, especially with the rise of multidrugresistant (MDR) strains. Phylogenetic diversity, pathotypic characterization, and antibiotic resistance profiles of E. c...
Sulfur-containing compounds from fungi
Garcia, Juliana; Silva, Jani; Gouvinhas, Irene; Guimarães, Rafaela; Bovolini, Antonio; Saavedra, Maria José; Alves, Maria JoséSulfur contributes greatly to the chemical richness of nature and, due to its unique properties, enables essential biological interactions that no other element can. Sulfur-containing compounds are bioactive/nutraceuticals substances from different sources, including fungi. They comprise sulfur atoms that are cyclically or noncyclically bonded to a cyanate group or a carbon atom. Sulfur-containing compounds, al...
Alkaloids from fungi
Silva, Jani; Garcia, Juliana; Guimarães, Rafaela; Palito, Cátia; Lemos, André; Barros, Lillian; Alves, Maria JoséThe prospection of unusual sources and undiscovered habitats is valuable in natural product research. Indeed, the fungi kingdom has received special attention since its ability to produce novel and intriguing secondary metabolites with various biological uses. Among secondary metabolites, alkaloid-derived structures present a wide range of bioactivities, including antineurodegenerative, antidepressive, anxiolyt...
Plasmatic microRNAs and treatment outcomes of patients with metastatic castrati...
Silva, Jani; Tavares, Valéria; Afonso, Ana; Garcia, Juliana; Cerqueira, Fátima; Medeiros, RuiProstate cancer (PCa) is one of the most common malignancies among men worldwide. Inevitably, all advanced PCa patients develop metastatic castration-resistant prostate cancer (mCRPC), an aggressive phase of the disease. Treating mCRPC is challenging, and prognostic tools are needed for disease management. MicroRNA (miRNA) deregulation has been reported in PCa, constituting potential non-invasive prognostic bio...
Sedentary behaviour impairs skeletal muscle repair modulating the inflammatory ...
Teixeira, Eduardo; Garcia, Juliana; Bovolini, António; Carvalho, Ana; Pacheco, Júlio; Duarte, José A.This study investigated whether sedentary behaviour modulates skeletal-muscle repair and tissue inflammatory response after cardiotoxin (CTX)-induced injury. Singly caged rats spent 8 weeks either as a sedentary group (SED, n = 15) or as a control group (EX, n = 15)—caged with running wheels for voluntary running. All rats had each tibial anterior muscle infused either with CTX (CTX; right muscle) or saline sol...
Eco-friendly insights on kiwiberry leaves valorization through in-vitro and in-...
Silva, Ana Margarida; Garcia, Juliana; Dall'Acqua, Stefano; Costa, Paulo; Delerue-Matos, Cristina; Rodrigues, FranciscaOn the last decade, the demand for novel active skin ingredients based on sustainable principles arise as a trend. These new concerns transformed the consumer preferences, which are not actually solved by the industry portfolio. Regulatory aspects establish guidelines to assess the safety and efficacy of new cosmetic ingredients, being this step imperative to introduce a new ingredient on the market. Our last s...
Bioactive polysaccharides from medicinal mushrooms: A review on their isolation...
Garcia, Juliana; Rodrigues, Francisca; Saavedra, Maria José; Nunes, Fernando M.; Marques, GuilherminaMushrooms either alone or in combination with conventional cancer treatment have been enhanced the efficacy of chemotherapy and radiotherapy improving the patients' quality of life. These therapy effects have been attributed to polysaccharides; the most potent compounds found in the fungi kingdom. Due to their wide range of biological activity and the backbone of glucose residues linked by β-(1 → 3)-glycosidic ...
Antimicrobial, Antibiofilm, and Antioxidant Properties of Boletus edulis and Ne...
Garcia, Juliana; Rodrigues, Francisca; Castro, Flávia; Aires, Alfredo; Marques, Guilhermina; Saavedra, Maria JoséMultidrug-resistant ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) has become the most recurrent global cause of skin and soft-tissue infections, belonging to the WHO priority pathogens list. Successful therapy remains challenging and entails the assessment of novel and successful antibiotics. In th...
