Valorisation of sea urchin (Paracentrotus lividus) gonads through canning
Camacho, Carolina; Oliveira, Helena; Serrano, Carmo; Delgado, Inês; Coelho, Inês; Pedro, Sónia; Lourenço, Helena; Bandarra, Narcisa M.; Marques, AntónioFresh sea urchin (Paracentrotus lividus) gonads are a delicacy with short seasonal availability, very often heterogeneous in size and intrinsic characteristics. This study aimed to valorise this resource through the preparation of canned products (with/without Porphyra spp.) and evaluate their physicochemical and sensory quality (3–12 months). Canning contributed to a decrease in protein, K and most carotenoids...
Mackerel and Seaweed Burger as a Functional Product for Brain and Cognitive Agi...
Cardoso, Carlos; Valentim, Jorge; Gomes, Romina; Matos, Joana; Rego, Andreia; Coelho, Inês; Delgado, Inês; Motta, Carla; Castanheira, IsabelMost world countries are experiencing a remarkable aging process. Meanwhile, 50 million people are affected by Alzheimer’s disease (AD) and related dementia and there is an increasing trend in the incidence of these major health problems. In order to address these, the increasing evidence suggesting the protective effect of dietary interventions against cognitive decline during aging may suggest a response to t...
Snapshot of resistome, virulome and mobilome in aquaculture
Salgueiro, Vanessa; Manageiro, Vera; Rosado, Tânia; Bandarra, Narcisa M.; Botelho, Maria João; Dias, Elsa; Caniça, ManuelaAquaculture environments can be hotspots for resistance genes through the surrounding environment. Our objective was to study the resistome, virulome and mobilome of Gram-negative bacteria isolated in seabream and bivalve molluscs, using a WGS approach. Sixty-six Gram-negative strains (Aeromonadaceae, Enterobacteriaceae, Hafniaceae, Morganellaceae, Pseudomonadaceae, Shewanellaceae, Vibrionaceae, and Yersiniacea...
First comparative genomic characterization of the MSSA ST398 lineage detected i...
Salgueiro, Vanessa; Manageiro, Vera; Bandarra, Narcisa M.; Ferreira, Eugénia; Clemente, Lurdes; Caniça, ManuelaStaphylococcus aureus ST398 can cause diseases in several different animals. In this study we analyzed ten S. aureus ST398 previously collected in three different reservoirs in Portugal (humans, gilthead seabream from aquaculture and dolphin from a zoo). Strains tested against sixteen antibiotics, by disk diffusion or minimum inhibitory concentration, showed decreased susceptibility to benzylpenicillin (all str...
Fatty acids, selenium, and vitamin B12 in chub mackerel (Scomber colias) as nou...
Afonso, Cláudia; Cardoso, Carlod; Gomes-Bispo, Ana; Ferreira, Inês; Rego, Andreia; Motta, Carla; Prates, José A.M; Castanheira, IsabelChub mackerel (Scomber colias) is an underutilised fish abundant in the North Atlantic and a nutritious food with high docosahexaenoic acid (DHA), selenium (Se), and vitamin B12 contents, affected by seasonality. Hence, the bioaccessibility of fatty acid (FA), Se, and vitamin B12 in chub mackerel was studied. Daily consumptions of 51 g, 35 g, and 14 g of March, June, and October chub mackerel, respectively, wou...
Exploring Omega-3′s impact on the expression of Bone-Related Genes in Meagre (A...
Luján-Amoraga, Leticia; Delgado-Martín, Belén; Lourenço-Marques, Cátia; J. Gavaia, Paulo; Bravo, Jimena; Bandarra, Narcisa M.; Dominguez, DavidDietary supplementation with Omega-3 fatty acids seems to promote skeletal health. Therefore, their consumption at imbalanced or excessive levels has offered less beneficial or even prejudicial effects. Fish produced in aquaculture regimes are prone to develop abnormal skeletons. Although larval cultures are usually fed with diets supplemented with Omega-3 Long Chain Polyunsaturated fatty acids (LC-PUFAs), the ...
Genomic Analysis of a mcr-9.1-Harbouring IncHI2-ST1 Plasmid from Enterobacter l...
Manageiro, Vera; Salgueiro, Vanessa; Rosado, Tânia; Bandarra, Narcisa M.; Ferreira, Eugénia; Smith, Terry; Dias, Elsa; Caniça, ManuelaThis study analyzed the resistome, virulome and mobilome of an MCR-9-producing Enterobacter sp. identified in a muscle sample of seabream (Sparus aurata), collected in a land tank from multitrophic fish farming production. Average Nucleotide Identity analysis identified INSAq77 at the species level as an Enterobacter ludwigii INSAq77 strain that was resistant to chloramphenicol, florfenicol and fosfomycin and w...

Carletti, Alessio; Cardoso, Carlos; Lobo-Arteaga, Jorge; Sales, Sabrina; Juliao, Diana; Ferreira, Inês; Chainho, Paula; Dionísio, Maria AnaBone metabolic disorders such as osteoporosis are characterized by the loss of mineral from the bone tissue leading to its structural weakening and increased susceptibility to fractures. A growing body of evidence suggests that inflammation and oxidative stress play an important role in the pathophysiological processes involved in the rise of these conditions. As the currently available therapeutic strategies a...
Differential effects of food restriction and warming in the two-spotted goby: i...
Lopes, Ana F.; Murdoch, Robyn; Martins-Cardoso, Sara; Madeira, Carolina; Costa, Pedro M.; Félix, Ana S.; Oliveira, Rui F.; Bandarra, Narcisa M.Climate change is a growing threat to marine organisms and ecosystems, and it is already modifying ocean properties by, for example, increasing temperature and decreasing pH. Increasing water temperature may also lead to an impairment of primary productivity and an overall depletion of available zooplankton. Understanding how the crossover between warming and zooplankton availability impacts fish populations ha...
