Nonalcoholic Fatty Liver Disease and Continuous Metabolic Syndrome in Adolescen...
Ferreira, Sofia; Mendes, Joana; Couto, Daniela; Ferreira, Dário; Rêgo, CarlaIntroduction: Nonalcoholic fatty liver disease is the leading cause of pediatric chronic liver disease. Although nonalcoholic fatty liver disease is closely associated with obesity, its relationship with metabolic syndrome in children is not fully understood. The main aim of this study was to evaluate the association between nonalcoholic fatty liver disease and a combination of cardiometabolic risk factors in a...
Short-communication: study of fatty acid metabolites in microbial conjugated fa...
Fontes, Ana Luiza; Neves, Bruna; Conde, Tiago; Couto, Daniela; Pimentel, Lígia Leão; Rodríguez-Alcalá, Luis Miguel; Domingues, M. RosárioMicrobially enriched food in conjugated linoleic (CLA) and conjugated linolenic (CLNA) acids is intensively studied nowadays. The conversion of linoleic (LA) and α-linolenic acids (α-LNA) into these compounds may involve different fatty acid (FA) intermediates. This research aimed to investigate potential FA byproducts in milk during microbial CLA/CLNA-enrichment using Bifidobacterium breve DSM 20091. Milk ferm...

Epidemiological and clinical aspects of Cutaneous and Mucosal Leishmaniases in ...
Rocha, Rafael; Conceição, Cláudia; Gonçalves, Luzia; Carvalho, Ana Cláudia; Maia, André; Martins, André; Carujo, António; Maio, António; Forra, CatarinaLeishmania infantum, a zoonotic vector-born parasite, is endemic in the Mediterranean region, presenting mostly as visceral (VL), but also as cutaneous (CL) and mucosal leishmaniasis (ML). This study aimed to describe the epidemiological and clinical aspects of the CL and ML cases diagnosed in mainland Portugal between 2010 and 2020. Collaboration was requested from every hospital of the Portuguese National Hea...
Optimization of Pavlova gyrans biomass production and the fatty acid profile us...
Maciel, José Filipe Gonçalves; Couto, Daniela; Geada, Pedro Miguel Macedo; Pereira, Hugo; Teixeira, J. A.; Domingues, M. Rosário; Silva, JoanaThis work aimed to optimize and characterize the biomass production of Pavlova gyrans through a sequential multivariate approach. Among seventeen cultivation parameters, light intensity, NaNO3, and CuSO4·5H2O were identified as the most significative factors (p < 0.10) for biomass productivity. Together with NaH2PO4·H2O, these variables were further studied in order to maximize the biomass production of P. gyra...

Maciel, Filipe; Couto, Daniela; Geada, Pedro; Pereira, Hugo; Teixeira, José; Domingues, M. Rosário; Silva, Joana; Vicente, AntónioThis work aimed to optimize and characterize the biomass production of Pavlova gyrans through a sequential multivariate approach. Among seventeen cultivation parameters, light intensity, NaNO3, and CuSO45H(2)O were identified as the most significative factors (p < 0.10) for biomass productivity. Together with NaH2PO4H2O, these variables were further studied in order to maximize the biomass production of P. gyra...
Production of lipid rich-extracts from Chlorella vulgaris using ohmic heating
Madureira, Leandro; Avelar, Zita; Conde, Tiago; Couto, Daniela; Domingues, M. Rosário; Domingues, Pedro; Pereira, Ricardo Nuno CorreiaMicroalgae biomass is a promising raw material for several bioproducts suitable for food, energy and pharmaceutical industries. The aim of the present work was to optimize the extraction of bioactive compounds from Chlorella vulgaris using Ohmic Heating (OH). A rotatable central composite design for two factors was used to assess the effects of temperature and solvent (% ethanol in water) on lipid extraction yi...
Applications of lipidomics in marine organisms: progress, challenges and future...
Rey, Felisa; Melo, Tânia; Lopes, Diana; Couto, Daniela; Marques, Francisca; Domingues, M. RosárioMarine ecosystems comprise a high diversity of life forms, such as algae, invertebrates, and vertebrates. These organisms have adapted their physiology according to the conditions of the environments in which they inhabit. In the last few years, the study of lipids of marine origin has received increasing attention due to the diversity of their composition. The progress of analytical techniques such as LC-MS an...
Chrysotila pseudoroscoffensis as a source of high-value polar lipids with antio...
Moreira, Ana S. P.; Gonçalves, Joana; Conde, Tiago A.; Couto, Daniela; Melo, Tânia; Maia, Inês Beatriz; Pereira, Hugo; Silva, JoanaMicroalgae are emerging as sustainable sources of a wide range of high-value compounds. However, the knowledge about microalgae polar lipids is still limited, despite their interest due to their chemical diversity and bioactivity. This study shows, for the first time, the polar lipidome of the haptophyte microalga Chrysotila pseudoroscoffensis unveiled by using hydrophilic interaction liquid chromatography-high...
Effects of outdoor and indoor cultivation on the polar lipid composition and an...
Couto, Daniela; Conde, Tiago A.; Melo, Tânia; Neves, Bruna; Costa, Margarida; Cunha, Pedro; Guerra, Inês; Correia, Nádia; Silva, Joana T.; Pereira, HugoNannochloropsis is a genus of eicosapentaenoic acid-rich microalgae with high levels of value-added polar lipids. However, the polar lipid composition of microalgal biomass is highly dependent on culture conditions (e.g., light or temperature), which are significantly different under indoor and outdoor culture conditions. In this study, we sought to investigate the plasticity of the polar lipid profile of a mar...
