Drug-induced sleep endoscopy: Characterization and comparison with Müller’s man...
Lombo, Catarina; Costa, Ricardo; Martins, Margarida; Matos, Carlos; Fonseca, RuiAims: Evaluate DISE findings in patients with obstructive sleep apnea and compare them with Müller r’s maneuver. Study design: Retrospective Material and Methods: Data collection from patients who underwent DISE from 2014 to 2019, including demographic data, anthropometric parameters and physical examination. Results: 28 patients underwent DISE. Velum was the most frequent site of airway collapse (92%) and obs...

Tratamento do vinho com resinas de troca iónica: Impacto no pH
Borges, Rita; Fernandes, Conceição; Marques, Celeste; Matos, Carlos; Vilela, Alice; Filipe-Ribeiro, Luis; Nunes, Fernando M.; Cosme, FernandaAo longo do processo de produção de vinho, o controle do pH é necessário já que influencia vários aspetos, como a cor, a eficiência do dióxido de enxofre, a acidez real, e também determinantemente a sua estabilidade microbiológica. A aplicação de resinas de troca iónica, particularmente de troca catiónica, permite a redução do pH do vinho com base na sua capacidade de trocar iões fixados em grupos funcionais, n...
Residual agroforestry biomass - thermochemical properties
Enes, Teresa; Aranha, José; Fonseca, Teresa; Matos, Carlos; Barros, Ana; Lousada, JoséResearch Highlights: Biomass from Mediterranean agroforestry vegetation may be a potential source of renewable energy. However, due to the high heterogeneity of this type of resource, the study of its characteristics becomes necessary for its e cient use. Objectives: The aim of this study was to evaluate the thermal and chemical properties of 14 di erent kinds of agroforestry biomass groups: shrubs, forest, and...

A complex scenario of tuberculosis transmission is revealed through genetic and...
Rito, Teresa S; Matos, Carlos; Carvalho, Carlos; Machado, Henrique Pedro Pereira Silva Amaral; Rodrigues, Gabriela; Oliveira, Olena; Ferreira, EduardaTuberculosis (TB) incidence is decreasing worldwide and eradication is becoming plausible. In low-incidence countries, intervention on migrant populations is considered one of the most important strategies for elimination. However, such measures are inappropriate in European areas where TB is largely endemic, such as Porto in Portugal. We aim to understand transmission chains in Porto through a genetic characte...
Tartrate stabilisation of Rosé wine using ion exchange resins
Borges, Rita; Fernandes, Conceição; Marques, Celeste; Matos, Carlos; Vilela, Alice; Nunes, Fernando M.; Cosme, FernandaTartaric stabilisation is essential to satisfy the quality criteria of wines. To prevent wine tartaric precipitates, potassium hydrogen tartrate (KHT) and calcium tartrate (CaT), several techniques can be used. The addition of oenological products, such as metatartaric acid and carboxymetilcelulose (CMC’s) as well as the use of ion exchange resins are acceptable techniques for tartaric stabilization by the OIV,...

Borges, Rita; Fernandes, Conceição; Marques, Celeste; Matos, Carlos; Vilela, Alice; Nunes, Fernando M.; Cosme, FernandaPara evitar a formac:;ao de precipitados de sais tartaricos no vinho, corno o hidrogenotartarato de potassio (KHT) eo tartarato neutro de cakio (CaT), varios tratarnentos podern ser utilizados. Estes precipitados, apesar de nao prejudicarem a saude, levarn a urna diminuic:;ao na aceitac:; ao do consurnidor e, corno consequencia, a uma dirninuic:;ao no valor cornercial do vinho. Na estabilizac:;ao tartarica de v...
Tartaric stabilization of Rosé wine by ion exchange resins: impact on phenolic ...
Cosme, Fernanda; Borges, Rita; Marques, Celeste; Matos, Carlos; Vilela, Alice; Filipe-Ribeiro, Luis; Nunes, Fernando M.; Fernandes, ConceiçãoWine tartaric stabilization is essential to satisfy the wine quality criteria, and consequently the consumer’s acceptance. Several techniques are available to prevent tartaric precipitation (potassium hydrogen tartrate and calcium tartrate) in wine. Beside the addition of enological products, the use of ion exchange resins is also an acceptable technique for wine tartaric stabilization by the OIV (OIV, 2016). H...
