Valorization of spent sugarcane fermentation broth as a source of phenolic comp...
Oliveira, Carla Maria; Horta, Bruno; Leal, Tânia; Pintado, Manuela; Oliveira, Catarina S. S.A methodology based on a solid phase extraction (SPE) was optimized for the recovery of phenolic compounds from the spent fermentation broth generated from Biofene® (trans-β-farnesene) production. For this purpose, two resins (XAD-2 and HP-20) and three desorption solutions (water, 50/50 ethanol/water, and ethanol) were tested. The most efficient resin revealed to be the HP-20, using ethanol as desorption solut...
Spent yeast valorization for food applications: effect of different extraction ...
Oliveira, Ana Sofia; Pereira, Joana Odila; Ferreira, Carlos; Faustino, Margarida; Durão, Joana; Pereira, Ana Margarida; Oliveira, Carla MariaOver the years, synthetic biology has been growing with the use of engineered yeast strains for the production of sustainable ingredients to meet global healthcare, agriculture, manufacturing and environmental challenges. However, as seen from the brewing industry perspective, these processes generate a substantial amount of spent yeast that contains high nutritional value related to its high protein content, s...
A incontinência urinária em mulheres praticantes de exercício recreativo: um es...
Silva, Maria Francisca; Costa, Rui Prado; Oliveira, Carla Maria; Moreira, SusanaA incontinência urinária afeta até um terço das mulheres em Portugal. O exercício pode ser fator precipitante/de exacerbação, mas também protetor, se for adequado. O objetivo deste estudo é determinar a prevalência de incontinência urinária em mulheres praticantes de exercício recreativo, avaliar a relação com o tipo de exercício e outros fatores de risco coexistentes, e aferir se o tema é abordado nos ginásios...
Urinary Incontinence in Women Who Practice Recreational Exercise: A Cross-Secti...
Silva, Maria Francisca; Prado Costa, Rui; Oliveira, Carla Maria; Moreira, SusanaIntroduction: Urinary incontinence affects up to one third of women in Portugal. Exercise can be a precipitating/aggravating factor but also protective, if appropriate. The aim of this study was to determine the prevalence of urinary incontinence in women who practice recreational exercise, to assess its relationship with the type of exercise and other coexisting risk factors, and assess whether the topic is ad...
Regional drinking water composition effects on hip fracture risk: a spatial ana...
Oliveira, Carla Maria; Teixeira, Hugo; Alves, Sandra Maria; Pina, Maria FátimaA variabilidade espacial existente na fratura do colo do fêmur (FCF) pode estar relacionada com a variabilidade geográfica da composição da água para consumo (CAC), devido à ação dos minerais na fragilidade óssea. O objetivo do artigo foi investigar o efeito da CAC no risco de FCF em Portugal (2000-2010). Do registo nacional de altas hospitalares, foram selecionadas todas as admissões em indivíduos ≥50, com dia...
Childhood cancer: incidence and spatial patterns in the city of Campinas, Brazi...
Oliveira Friestino, Jane Kelly; Mendonça, Denisa; Oliveira, Pedro; Oliveira, Carla Maria; Moreira Filho, Djalma De CarvalhoThis article analyzes cancer incidence and spatial patterns in children and adolescents (0-19 years of age) residing in the city of Campinas in Southeastern Brazil who were diagnosed from 1996-2005. Cancers were classified according to the Third International Classification of Childhood Cancer (ICCC-3) Groups. The four most common groups were studied: leukemias, lymphomas, and central nervous system and soft ti...
Quinones as Strecker degradation reagents in wine oxidation processes
Oliveira, Carla Maria; Santos, Sónia A. O.; Silvestre, Armando J. D.; Barros, António S.; Ferreira, António César Silva; Silva, Artur M. S.The Strecker aldehydes formed during the reaction between α-amino acids (phenylalanine or methionine) and either gallic acid, caffeic acid or (+)-catechin ortho-quinones were evaluated in wine-model systems. It was demonstrated that phenylacetaldehyde was formed by quinone intermediates at wine pH. The highest amounts of phenylacetaldehyde during the 10days of experiment (69±5µg/L/day; 7x>Control) were obtained...
Spatial analysis of small ruminant Brucellosis occurrence in Trás-Os-Montes and...
Duque, C.; Oliveira, Carla Maria; Mendes, C.; Pina, Maria Fátima; Niza-Ribeiro, J.Small ruminant brucellosis (SRB) is a zoonotic disease caused by Brucella melitensis responsible for economic losses from decreased productivity and lost trade in endemic regions. Although an ongoing national official disease control program is implemented, the efforts in eradicating the disease in Trás-os-Montes and Alto Douro, a region in Northeast of Portugal have not so far been successful, particularly in ...
Spatial-temporal analysis of climate factors effects on hospitalization due to ...
Oliveira, Carla Maria; Alves, Sandra Maria; Bessa, Ana Catarina; Pina, Maria Fátima; Alves, Sandra Maria; Oliveira, Carla MariaA higher risk of falls in winter, when compared to summer, has been reported, although climatic factors as risk factors for falls have been little studied. Our aim is to identify the effects of climatic factors (CF) on the spatial-temporal distribution of hospitalization for fall-related injuries in older adults (2000-2010).
Strong spatial inequalities in the nutrition status of elderly (Portugal)
Oliveira , Carla Maria; Magalhães, Bruna; Alves, Sandra; Romano, João; Afonso, C.; Moreira, P.; Padrão, P.; Santos, A.; Borges, N.; Amaral, T. F.Within Nutrition UP 65 study nutritional health problems of the elderly Portuguese population were described, but it of major relevance to identify target vulnerable groups for public health interventions. This analysis aims to identify clusters of priority intervention in the improvement of the nutritional deficit in this population.
