Tularaemia: A challenging zoonosis
Carvalho, C.L.; Lopes de Carvalho, I.; Zé-Zé, L.; Núncio, M.S.; Duarte, E.L.In recent years, several emerging zoonotic vector-borne infections with potential impact on human health have been identified in Europe, including tularaemia, caused by Francisella tularensis.This remarkable pathogen, one of the most virulent microorganisms currently known, has been detected in increasingly new settings and in a wide range of wild species, including lagomorphs, rodents, carnivores, fish and inv...
Urinary Estrogen Metabolites and Self-Reported Infertility in Women Infected wi...
Santos, J.; Gouveia, M.J.; Vale, N.; Delgado, M. de L.; Gonçalves, A.; da Silva, J.M.; Oliveira, C.; Xavier, P.; Gomes, P.; Santos, L.L.; Lopes, C.Schistosomiasis is a neglected tropical disease, endemic in 76 countries, that afflicts more than 240 million people. The impact of schistosomiasis on infertility may be underestimated according to recent literature. Extracts of Schistosoma haematobium include estrogen-like metabolites termed catechol-estrogens that down regulate estrogen receptors alpha and beta in estrogen responsive cells. In addition, schis...
Comportamentos face aos resíduos de embalagens e medicamentos fora de uso
Nascimento, Luís; Taboada, Xavier; Cardoso, Marisa; Ferreira, L.; Lopes, Ivo; Torres, RuiOs medicamentos têm um papel importante na prevenção e tratamento das doenças do Homem e dos animais, no entanto, contêm substâncias químicas que podem contaminar o solo e a água, não devendo ser colocados no lixo comum. O problema é que boa parte da população não sabe disso ou mesmo sabendo não lhe dá o devido valor.1 A eliminação destes resíduos pela rede de esgotos ou pelo sistema de resíduos urbanos tem con...
A satisfação dos utentes com os cuidados de saúde primários
Mendes, F. M.; Mantovani, M. F.; Gemito, M. L.; Lopes, M. J.Contexto: a satisfação dos utentes com as instituições de saúde é prioritária pois as necessidades e expectativas destes estão em constante transformação logo, as instituições devem adotar formas de organização e gestão empreendedoras, adaptadas a estas necessidades. Objetivos: conhecer a satisfação global dos utentes em relação aos fatores organizacionais e atendimento nos Centros de Saúde (CS) e Unidades de ...
Impact of weather regimes on the wind power ramp forecast
Couto, A.; Costa, P.; Rodrigues, L.; Lopes, Vitor V.; Estanqueiro, AnaThe stochastic nature of wind and the continuous need to balance electric generation with demand poses serious challenges to the power system operators. The impact of large wind integration into the power system is mitigated by decreasing the uncertainty associated with wind forecasts. In particular, the forecast of severe wind power ramps is important due to its impact on the energy market and grid operation ...
Diversity in UV sensitivity and recovery potential among bacterioneuston and ba...
Santos, A. L.; Lopes, S.; Baptista, I.; Henriques, I.; Gomes, N. C. M.; Almeida, A.; Correia, A.; Cunha, A.Aims: To assess the variability in UV-B (280–320 nm) sensitivity of selected bacterial isolates from the surface microlayer and underlying water of the Ria de Aveiro (Portugal) estuary and their ability to recover from previous UVinduced stress. Methods and Results: Bacterial suspensions were exposed to UV-B radiation (3Æ3 W m)2). Effects on culturability and activity were assessed from colony counts and 3H-leu...
Endothelial function in patients with metabolic syndrome and erectile dysfuncti...
Tomada, N; Tomada, I; Botelho, F; Pacheco-Figueiredo, L; Lopes, T; Negrão, R; Pestana, M; Cruz, FErectile dysfunction (ED) is a highly prevalent disease whose aetiology is mostly vasculogenic. It is nowadays considered a marker of future cardiovascular events reflecting the underlying endothelial dysfunction, the common link with the metabolic syndrome (MetS). The recent association between MetS, endothelial dysfunction and peripheral artery disease, but not with coronary artery disease (CAD), suggests tha...

RPC-PET: status and perspectives
M. Couceiro; A. Blanco; Nuno C. Ferreira; R. Ferreira Marques; P. Fonte; L. LopesThe status of the RPC-PET technology for small animals is briefly reviewed and its sensitivity performance for human PET studied through Monte-Carlo simulations. The cost-effectiveness of these detectors and their very good timing characteristics open the possibility to build affordable TOF-PET systems with very large fields of view. Simulations suggest that the sensitivity of such systems for human wholebody s...
Biomassa e energia no Nordeste de Portugal
Azevedo, João; Feliciano, Manuel; Tarelho, L.; Lopes, Helena; Fonseca, Felícia; Nunes, Luís; Patrício, Maria do Sameiro; Ribeiro, A.C.A conversão de biomassa lenhosa em energia térmica em Trás-os-Montes é uma prática corrente e relevante do ponto de vista florestal e energético. O aproveitamento desta fonte de energia é feito, contudo, com base em iniciativas individuais, não existindo nenhuma estratégia local, regional ou nacional para a utilização de biomassa para produção de energia de forma integrada, eficiente e sustentada. Com a execu...
