Unraveling the microbiome–environmental change nexus to contribute to a more su...
Barbosa, Maria Inês; Silva, Gabriel; Ribeiro, Pedro; Vieira, Eduarda; Perrotta, André; Moreira, Patrícia; Rodrigues, Pedro MiguelThis review aims to explore the literature to assess the potential of artificial intelligence (AI) in environmental monitoring for predicting microbiome dynamics. Recognizing the significance of comprehending microorganism diversity, composition, and ecologically sustainable impact, the review emphasizes the importance of studying how microbiomes respond to environmental changes to better grasp ecosystem dynami...
Classification of sleep quality and aging as a function of brain complexity: a ...
Penalba-Sánchez, Lucía; Silva, Gabriel; Crook-Rumsey, Mark; Sumich, Alexander; Rodrigues, Pedro Miguel; Oliveira-Silva, Patrícia; Cifre, IgnacioUnderstanding and classifying brain states as a function of sleep quality and age has important implications for developing lifestyle-based interventions involving sleep hygiene. Current studies use an algorithm that captures non-linear features of brain complexity to differentiate awake electroencephalography (EEG) states, as a function of age and sleep quality. Fifty-eight participants were assessed using the...
Exploring the relationship between CAIDE dementia risk and EEG signal activity ...
Manuel, Alice Rodrigues; Ribeiro, Pedro; Silva, Gabriel; Rodrigues, Pedro Miguel; Nunes, Maria Vânia SilvaBackground: Accounting for dementia risk factors is essential in identifying people who would benefit most from intervention programs. The CAIDE dementia risk score is commonly applied, but its link to brain function remains unclear. This study aims to determine whether the variation in this score is associated with neurophysiological changes and cognitive measures in normative individuals. Methods: The sample ...

Validation of psychophysiological measures for caffeine oral films characteriza...
Batista, Patrícia; Rodrigues, Pedro Miguel; Ferreira, Miguel; Moreno, Ana; Silva, Gabriel; Alves, Marco; Pintado, Manuela; Oliveira-Silva, PatríciaBackground: The oral films are a new delivery system that can carry several molecules, such as neuromodulator molecules, including caffeine. These delivery systems have been developed and characterized by pharmacokinetics assays. However, new methodologies, such as psychophysiological measures, can complement their characterization. This study presents a new protocol with psychophysiological parameters to chara...
COVID-19 activity screening by a smart-data-driven multi-band voice analysis
Silva, Gabriel; Batista, Patrícia; Rodrigues, Pedro MiguelCOVID-19 is a disease caused by the new coronavirus SARS-COV-2 which can lead to severe respiratory infections. Since its first detection it caused more than six million worldwide deaths. COVID-19 diagnosis non-invasive and low-cost methods with faster and accurate results are still needed for a fast disease control. In this research, 3 different signal analyses have been applied (per broadband, per sub-bands a...

No. of bitstreams: 0 Previous issue date: 2021-08-02; Chalcones (1,3-diaryl-2-propen-1-ones) are naturally occurring polyphenols with known anticancer activity against a variety of tumor cell lines, including osteosarcoma (OS). In this paper, we present the preparation and characterization of spheres (~2 mm) from polyvinyl alcohol (PVA) containing a combin...
Sistema de Apoio à Decisão para a escolha de tecnologia de reaproveitamento de ...
Silva, GabrielTodos os anos, o Brasil consome nada menos que 41.000 toneladas de alimentos. Entre eles, 15% ocorreram em restaurantes, totalizando aproximadamente 6.000 toneladas. Esses desperdícios ocorrem durante ou após o preparo dos alimentos, e os alimentos geralmente não são utilizados adequadamente. Para reduzir o desperdício de alimentos , é preciso planejar melhores compras, investir em equipamentos , treinar a equi...
A Portuguese Treatise on the Plague: João Curvo Semedo's Tratado da Peste
Silva, GabrielJoão Curvo Semedo (1635-1719) is the author of, among other works, the Tratado da Peste (1680), a treatise concerning the origins and causes of the plague, and its prevention and treatment. This article aims to present this opus, which has long been neglected, to understand how it follows the tradition of the genre of 'plague literature', and to highlight its value and originality. This analysis draws upon othe...
