Beer enriched with “Lapins” cherry extracts: antioxidant activity and liver tox...
Santos, Diana; Pereira, Maria João; Oliveira, Ana Isabel; Pinho, CláudiaBackground: Beer can be considered a functional beverage and integrate innovative ingredients, namely sweet cherries, with different properties, such as antioxidant activity [1,2]. Objective: To evaluate the antioxidant activity, in vitro, and liver toxicity, in human hepatocarcinoma cells (HepG2), in beer after incorporation of aqueous (CAE) and ethanolic (CEE) extracts of cherry variety "Lapins". Methods: CAE...
Potential skin benefits of incorporating Prunus avium Lapins extracts into a co...
Pereira, Maria João; Santos, Diana; Pinho, Cláudia; Oliveira, Ana IsabelBackground: A commercially available Portuguese India Pale Ale craft beer (ALM-IPA) has shown potential skin benefits in a previous study [1]. However, the incorporation of cherry extracts into bottled beers lacks scientific evidence. Objective: To evaluate, in vitro, the benefits of incorporating aqueous (ACE) and ethanolic (ECE) cherry extracts into ALM-IPA beer, in terms of antioxidant and photoprotective ac...
Sugarcane straw hemicellulose extraction by autohydrolysis for cosmetic applica...
Pereira, Maria João; Pedrosa, Sílvia S.; Costa, Joana R.; Carvalho, Maria João; Neto, Tânia; Oliveira, Ana L.; Pintado, Manuela; Madureira, Ana RaquelSugarcane is a popular crop whose cultivation generates a wide range of by-products. The aim was to optimize the hydrothermal extraction of hemicellulose from sugarcane straw using response-surface methods with a two-factor composite design and to assess its functional qualities. Three process parameters were subject to optimization: solid/liquid ratio (1:6–1:18), temperature (143–186 °C), and extraction time (...
Colheitas nos GMLF para Investigações de Parentesco do SGBF-N
Ferreira da Silva, Benedita; Amorim, António; Pereira, Maria JoãoO SGBF é responsável pela realização de perícias de Investigação de Parentesco, Criminalística e Identificação Individual. As perícias de IP correspondem a cerca de 20-30% da totalidade das perícias no SGBF-N. Frequentemente reveste-se de necessidade recorrer aos GMLF para a realização da colheita a intervenientes em IP considerando a área de residência das mesmas. Para uma boa realização da perícia e recolha d...
Perícias de Identificação Individual: dificuldades, obstáculos e soluções para ...
Ferreira da Silva, Benedita; Pereira, Maria João; Cerqueira, Joana; Pontes, Lurdes; Amorim, AntónioAs perícias de Identificação Individual (II) no SGBF referem-se a processos que visam determinar a identificação de cadáveres, restos cadavéricos, fetos, ou confirmação de identidade de amostras biológicas, recorrendo à análise de ADN. A identificação genética pode ser efetuada por comparação direta, recorrendo a amostras colhidas antemortem e objetos pessoais, ou de forma indireta, por comparação genética com ...
RESULTADO NÃO ESPERADO. A PROPÓSITO DE UM CASO DE IDENTIFICAÇÃO GENÉTICA INDIVI...
Cerqueira, Joana; Pereira, Maria João; Matos, Paula; Amorim, AntónioNas perícias de Genética Forense, a identificação de amostras em análise, requer sempre a comparação com amostras de referência, sejam pertencentes ao próprio ou a familiares, de modo a permitir tirar conclusões e a realizar uma valorização estatística da prova. No caso concreto das perícias de Identificação Genética Individual, as amostras de um desconhecido (cadáver ou restos cadavéricos), são comparadas com ...
Exploring alternative potentialities of portuguese and spanish craft beers: ant...
Pereira, Maria João; Santos, Diana; Cruz, Agostinho; Jesus, Ângelo; Martins, João P.; Moreira, Fernando; Santos, Marlene; Pinho, CláudiaCraft beer has gained popularity due to its unique sensory characteristics and complex matrix with nutritional and potential health benefits. Studies linking beer consumption to skin conditions are limited, however, the high content of bioactive compounds is related to biological activities such as antibacterial, anti-inflammatory, anti-oxidative, and anti-carcinogenic. This study aims to evaluate the antioxida...
Biofeedback-based method for real-time fatigue monitoring of knee
Franco, Tiago; Henriques, Pedro; Alves, Paulo; Pereira, Maria João; Leitão, Paulo; Azevedo, NelsonThis paper introduces and implements a method to monitor muscle fatigue in real-time using a wearable biofeedback system to improve muscle rehabilitation treatments. The biofeedback system consists of an electromyography (EMG) sensor to capture muscle activity and two motion sensors to track knee angles. The proposed method for monitoring muscle fatigue involves three steps: (1) recognition of the movement phas...
Purification of stilbenes from grape stems in a continuous process based on pho...
Bzainia, Amir; Igrejas, Getúlio; Pereira, Maria João; Costa, Mário Rui; Dias, RolandoThis study presents a sustainable method to purify stilbenes from residual grape stem biomass. This approach was experimentally validated through the use of a pilot size fixed-bed adsorption prototype for the automation of the purification process. Molecularly imprinted polymers, synthesized through photopolymerization at room temperature and incorporating the 4-vinylpyridine monomer, serve as adsorbents. The p...
A Neural Network-Based Approach to Identifying Wrinkles and Recommending Cosmet...
Tonello, Guilherme de M.; Alves, Paulo; Ortoncelli, André Roberto; Pereira, Maria JoãoSkincare has become a constant demand among the population, who are increasingly concerned about their health. Furthermore, environmental issues arouse the interest of the masses in natural and sustainable products. This project proposes an approach for recommending thermal-based products based on a set of information provided by the user, combined with the results of computer vision algorithms (to identify the...
