Preserving and hydrogel-matrixing the bioactive properties of aromatic medicina...
Parracho, Tiago; Cruz, Pedro F.; Peralta, Claúdia C.; Silva, Cândida G.; Campos, Maria Jorge; Neves, Marta; Cordeiro, Rachel; Trindade, DanielaEdible wild plants are part of the ethnobotanic heritage of a certain geographical area and are important sources of essential oils, antioxidants, minerals, and special flavours. Corema album (Portuguese crowberry), Crithmum maritimum (sea fennel), Eryngium maritimum (sea holly), Helichrysum italicum (curry plant) and Otanthus maritimus (cottonweed) wildly flourish along the sandy dunes of the coast of the Iber...
Oxidative Stability of Sunflower Oil Enriched with Fig Tree Leaves Bioactive Co...
Pinteus, Susete; Neves, Marta; Tecelão, Carla; Silva, Susana; Cruz, Alexandra; Bernardino, Susana; Mendes, Vasco; Vaz, Daniela; Campos, Maria JorgeThe pressure imposed by the increase of world’s population and climate change makes it imperative to find sustainable strategies to optimize food resources and decrease waste production based on circular economy principles. This work evaluated the potential of fig tree leaves to reduce the oxidation of sunflower oil when exposed to frying temperatures. The bioactive compounds extracted directly from fig tree le...
Marine endophytic fungi associated with Halopteris scoparia (Linnaeus) Sauvagea...
Calado, Maria da Luz; Silva, Joana; Alves, Celso; Susano, Patrícia; Santos, Débora; Alves, Joana; Martins, Alice; Gaspar, Helena; Pedrosa, RuiMarine fungi and, particularly, endophytic species have been recognised as one of the most prolific sources of structurally new and diverse bioactive secondary metabolites with multiple biotechnological applications. Despite the increasing number of bioprospecting studies, very few have already evaluated the cosmeceutical potential of marine fungal compounds. Thus, this study focused on a frequent seaweed in th...
Identification of the main quinolone resistance determinant in Campylobacter je...
Hormeño, Lorena; Palomo, Gonzalo; Ugarte-Ruiz, María; Porrero, M. Concepción; Borge, Carmen; Vadillo, Santiago; Píriz, Segundo; Domínguez, LucasAmong zoonotic diseases, campylobacteriosis stands out as the major bacterial infection producing human gastroenteritis. Antimicrobial therapy, only recommended in critical cases, is challenged by resistance mechanisms that should be unambiguously detected for achievement of effective treatments. Quinolone (ciprofloxacin) resistance of Campylobacter jejuni and Campylobacter coli, the2main Campylobacter detected...
Detection of QnrB54 and Its Novel Genetic Context in Citrobacter freundii Isola...
Campos, Maria Jorge; Palomo, Gonzalo; Hormeño, Lorena; Rodrigues, Américo; Sánchez-Benito, Rosario; Píriz, Segundo; Quesada, AlbertoLETTER Quinolone resistance in Enterobacteriaceae is mediated by mutations in the quinolone resistance-determining regions (QRDR) of topoisomerase genes and/or by plasmid-mediated quinolone resistance determinants (PMQR) such as the qnr genes encoding pentapeptide repeat proteins (1). The qnrB family is represented by 80 different alleles (http://www.lahey.org/qnrStudies/); most of them originated from Citrobac...
