A Review of the Use of Chestnut in Traditional and Innovative Food Products.

Guiné, Raquel; Costa, Cátia; Florença, S. G.; Correia, Paula

Chestnuts have been consumed in Portugal for immemorial times. These fruits are highly appreciated, not only due to their organoleptic characteristics but also due to their nutritional and functional values. For the nutrients to be more accessible and for the chestnuts to have better flavour and digestibility, it is necessary to heat, cook or roast them, for example. Chestnuts are a very versatile food, in term...


Modulatory effect of Gracilaria gracilis on European seabass gut microbiota com...

Gonçalves, Ana Teresa; Simões, Marco; Costa, Cátia; Passos, Ricardo; Baptista, Teresa

Seaweeds are an important source of nutrients and bioactive compounds and have a high potential as health boosters in aquaculture. This study evaluated the effect of dietary inclusion of Gracilaria gracilis biomass or its extract on the European seabass (Dicentrarchus labrax) gut microbial community. Juvenile fish were fed a commercial-like diet with 2.5% or 5% seaweed biomass or 0.35% seaweed extract for 47 da...

Real-time PCR protocol for detection and quantification of three pathogenic mem...

Costa, Cátia; Ferreira, Guilherme D.; Simões, Marco; Silva, Joana L.; Campos, Maria J.

Vibriosis, an often-fatal disease induced by pathogenic members of the Vibrionaceae family, causes severe economic losses in aquacultures. To mitigate/avoid vibriosis outbursts, it is vital to detect and quantify these pathogens as early as possible. However, standard microbiological methods are time-consuming and often underestimate cell counts, which calls for the development of valid alternatives. In this st...

Detection of mcr-1 Gene in undefined Vibrio species isolated from clams

Valdez, Christian; Costa, Cátia; Simões, Marco; Carvalho, Carla C. C. R. De; Baptista, Teresa; Campos, Maria

The increase of antimicrobial resistant strains is leading to an emerging threat to public health. Pathogenic Vibrio are responsible for human and animal illness. The Enterobacteriaceae family includes microorganisms that affect humans, causing several infections. One of the main causes of human infection is related to the ingestion of undercooked seafood. Due to their filterfeeding habit, marine invertebrates,...

Olhar sociológico sobre o mundo: debates nas escolas secundárias. Reflexões e p...

Alves, Ângela; Lacerda, Beatriz; Costa, Cátia; Parente, Cristina; Azevedo, Natália

The article proposes an experiential narrative of the project "A sociological perspective of the world: debates in high schools", integrating a reflexive analysis on its construction, implementation and evaluation. The theoretical principles are rooted in a combinatorial proposal between formal and non-formal education and on meaningful learning for high school audiences. The project is part of the university's...


The educational software in the physics teaching and learning process

Costa, Cátia; Cravino, J. Paulo; Lopes, J. Bernardino

When the student is an active subject in learning, teaching activities become attractive, efficient and engaging. Educational software, such as simulations and online games, its playful and fun character promotes the active role of the student, can prove to be pedagogical strategies to ascertain the acquisition of learning carried out in teaching and learning process. However, it is essential to change teaching...

The interplay between atmospheric conditions and grape berry quality parameters...

Costa, Cátia; Graça, António; Fontes, Natacha; Teixeira, Marta; Gerós, H.; Santos, João A.

The atmospheric conditions are a strong modulator of grape berry composition, but further research is required to better understand this relationship, which is particularly pertinent under the context of climate change. The present study assesses the relationship between interannual variability in atmospheric conditions (mean, maximum and minimum air temperatures and precipitation totals) on grape berry quality...
