Assessing the potential of brewer’s spent grain to enhance cookie physicochemic...
Nicolai, Marisa; Palma, Maria Lídia; Reis, Ricardo; Amaro, Rúben; Fernandes, Jaime; Gonçalves, Elsa M.; Silva, Mafalda; Lageiro, ManuelaBrewers’ spent grain (BSG), the major by-product of the brewery industry, has high nutritional value, making it suitable for upcycling into products such as healthy, and sustainable cookies. Nonetheless, the incorporation of BSG in cookies can impact their quality, given the increased fiber and protein content. This work explored the effect of replacing wheat flour with BSG at 50% and 75% in cookie formulations...
Ecotoxicity of the non-dioxin-like PCB-153 in the model marine diatom Phaeodact...
Duarte, Bernardo; Cardoso, João; Feijão, Eduardo; Carreiras, João Albuquerque; Cruz De Carvalho, Ricardo; Matos, Ana Rita; Fonseca, Vanessa F.Despite the ban on polychlorinated biphenyls (PCBs) in developed countries since the 1930s, their persistence and use endured in developing countries, with reported toxic effects on various organisms. PCB congener 153 (PCB-153, 2, 2′, 4, 4′, 5, 5′–hexachlorobiphenyl) is notably prevalent in marine biota. However, its mode of action and impact on primary marine diatoms are not well documented. Phaeodactylum tric...
Persistent Organic Pollutants in Tagus Estuary Salt Marshes: Patterns of Contam...
Cruz De Carvalho, Ricardo; Cardoso, João; Carreiras, João Albuquerque; Santos, Paula; Palma, Carla; Duarte, BernardoThe presence of anthropogenic compounds, including organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), was studied in three salt marshes within the Tagus estuary, Portugal, along an anthropogenic pressure gradient. Results revealed differences in OCPs and PCBs among the marshes, with differing concentration levels. Specifically, one marsh, with surrounding agricultural activity, showed the hi...
Potential for coastal and offshore aquaculture in Portugal: Insights from physi...
Mosqueira, Miguel; Pombo, Ana; Borges, Carlos; Brito, Ana C.; Zacarias, Nuno; Esteves, Rita; Palma, CarlaPhysico-chemical and biological parameters along the Portuguese coast were analyzed to evaluate the potential to produce aquatic species of economic interest. Water samples were collected in 2018 and 2019 in five different areas of the Portuguese coast. Currents data were collected between 2018 and 2020 and historical waves height data from 1988 to 2019. According to the results, there is a wide variety of spec...
Problemas ambientais relacionados com a dragagem de sedimentos poluídos
Fonseca, Rita; Palma, CarlaA dragagem é uma das técnicas mais eficientes na recuperação de um corpo de água, sendo a única capaz de remover total ou parcialmente os sedimentos, local preferencial de acumulação e retenção de elementos poluentes. É um método economicamente viável quando comparado com outros programas de reabilitação e uma das grandes vantagens relativamente a métodos químicos ou biológicos, é a não introdução de substância...
Immunometabolic pathways in BCG-induced trained immunity
Arts, Rob, J. W.; Carvalho, Agostinho Albérico Rodrigues; Rocca, Claudia La; Palma, Carla; Rodrigues, Fernando José dos Santos; Silvestre, RicardoThe protective effects of the tuberculosis vaccine Bacillus Calmette-Guerin (BCG) on unrelated infections are thought to be mediated by long-term metabolic changes and chromatin remodeling through histone modifications in innate immune cells such as monocytes, a process termed trained immunity. Here, we show that BCG induction of trained immunity in monocytes is accompanied by a strong increase in glycolysis an...
Major and minor element geochemistry of deep-sea sediments in the Azores Platfo...
Palma, Carla; Oliveira, Anabela; Valença, Manuela; Cascalho, João; Pereira, Eduarda; Lillebø, Ana I.; Duarte, Armando C.; Pinto de Abreu, ManuelThe Azores Platform and the Irving and Great Meteor seamounts south of the archipelago (38°N-29°N) have rarely been studied geochemically, a fact which is surprising given that they represent the south-eastern limit of region V outlined in the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR Convention). The main aim of the present work was therefore to characterise the ...
Water column characterisation on the Azores platform and at the sea mounts sout...
Palma, Carla; Lillebø, Ana I.; Borges, Carlos; Souto, Miguel; Pereira, Eduarda; Duarte, Armando C.; Abreu, Manuel Pinto deThis study provides data concerning the hydrography and water chemistry of the Atlantic region between 29-38° N and 27-31° W, and establishes background values for dissolved Cu, Cd, Pb and As. Three water masses were identified: the Eastern North Atlantic Central Water (ENACW), the Mediterranean Water (MW) and the North Atlantic Deep Water (NADW). The ENACW exhibits a clear meridional gradient of temperature an...
