Living on the Edge: Management and Conservation of Atlantic Salmon at the South...
Alexandre, C.; Silva, S.; Mateus, C.S.; Lança, M.J.; Quintella, B.R.; Belo, A.F.; Domingues, A.; Rato, A.S.; Oliveira, R.; Moreira, A.; Pereira, J.Atlantic salmon (Salmo salar L.) are an emblematic anadromous fish species that inhabit marine and freshwater ecosystems in the Northern Hemisphere. In Portugal, the southern limit of its global distribution range, the species is classified as Critically Endangered (CR), and occurs only in the Minho and Lima rivers, which hold the most abundant populations, with occasional confirmed occurrences in the Cávado an...
Physiopathological responses of sole (Solea senegalensis) subjected to bacteria...
Peixoto, M.J.; Domingues, A.; Batista, S.; Gonçalves, J.F.M.; Gomes, A.M.; Cunha, S.; Ozorio, R.O.A.This study aimed to evaluate the protective effects of four autochthonous bacteria isolated from juvenile sole (Solea senegalensis) intestine as dietary probiotic supplement against bacterial pathogen infection and handling/transport stressors. Growth performance and immune responses were evaluated after 85 days of feeding trial. Sole (IBW=16.07 ± 0.11 g) were fed six experimental diets, a control diet (CTRL, w...

Síndrome Cerebro-Costo-Mandibular. A Propósito de Um Caso Clínico
Mota, Céu R.; Tavares, C.; Ovelheiro, A.; Sousa, A.; Domingues, A.; Figueiredo, A.; Santos, C.; Lima, M R.A Síndrome Cerebrocostomandibular é caracterizada logo ao nascimento por unia sequência de Pierre Robin grave (micrognatia grave, fenda do palato e glossoptosis) e defeitos posteriores da grade costal, ocorrendo atraso mental em 50% dos casos que sobrevivem. A morte por complicações respiratórias ocorre em 40% dos casos antes do primeiro ano de vida. Os autores descrevem um caso de Síndrome Cerebrocostomandibul...
Marine origin collagen membranes for drug delivery
Marques, A. P.; Domingues, A.; Silva, Joana M.; Perez-Martin, R. I.; Sotelo, C. G.; Silva, Tiago H.; Reis, R. L.Introduction: Collagen is the most abundant protein of animal connective tissues, found in skins, bones or cartilages, which turn it into one of the key polymers to be considered for biomedical applications, namely tissue engineering and drug delivery. Current industrial procedures to extract collagen involves bovine and porcine as main sources. However, due to religious factors and the risk of transmitting dis...
Marine origin collagens and its potential applications
Silva, Tiago H.; Silva, Joana M.; Marques, A. P.; Domingues, A.; Bayon, Yves; Reis, R. L.Collagens are the most abundant high molecular weight proteins in both invertebrate and vertebrate organisms, including mammals, and possess mainly a structural role, existing different types according with their specific organization in distinct tissues. From this, they have been elected as one of the key biological materials in tissue regeneration approaches. Also, industry is constantly searching for new nat...
Fast growing fungi: a problem to be solved to achieve characterization of occup...
Nunes, Ana Carolina; Domingues, A.; Malta-Vacas, Joana; Viegas, CarlaChrysonilia sitophila is a common mould in cork industry and has been identified as a cause of IgE sensitization and occupational asthma. This fungal species have a fast growth rate that may inhibit others species’ growth causing underestimated data from characterization of occupational fungal exposure. Aiming to ascertain occupational exposure to fungi in cork industry, were analyzed papers from 2000 about the...
Exposure to fungi in cork: potential occupational hazard
Nunes, Ana Carolina; Domingues, A.; Almeida-Silva, Marina; Viegas, Susana; Viegas, CarlaCork is a light, porous and impermeable material extracted from the bark of some trees. It is in manufacture of stoppers for wine bottles the main application of cork. It is estimated that the area occupied by cork oaks in the Iberian Peninsula is around 33% in Portugal and 23% in Spain. The world production of cork is focused in the south Europe, with Portugal being the most important producer followed by Spai...
New improved method for fructooligosaccharides production by Aureobasidium pull...
Domingues, A.; Nobre, C.; Rodrigues, L.R.; Peres, A.M.; Torres, Duarte; Rocha, I.; Lima, N.; Teixeira, JoséFructooligosaccharides are prebiotics with numerous health benefits within which the improvement of gut microbiota balance can be highlighted, playing a key role in individual health. In this study, an integrated one-stage method for FOS production via sucrose fermentation by Aureobasidium pullulans was developed and optimized using experimental design tools. Optimization of temperature and agitation speed for ...
