The silent extinction of freshwater mussels in Portugal
Lopes-Lima, M.; Reis, J.; Alvarez, Maria G.; Anastácio, P. M.; Banha, F.; Beja, P.; Castro, P.; Gama, Mafalda; Gil, M. G.; Gomes-dos-Santos, A.Freshwater mussels are one of the most threatened animal groups in the world. In the European Union, threatened and protected mussel species are not adequately monitored, while species considered to be common and widespread receive even less attention. This is particularly worrying in the Mediterranean region, where species endemism is high and freshwater habitats are severely affected by water scarcity. In the...

Mercê, Cristiana; Catela, David; Silva, B.; Gonçalves, F.; Mota, E.; Costa, B.; Julião, S.; Martins, M.; Catanho, L.; Sousa, R.; Bernardino, F.No karaté o movimento está em estreita articulação com um fluxo respiratório diafragmático controlado. Como a respiração diafragmática ativa o sistema nervoso parassimpático e reduz a frequência respiratória (CR), fomos verificar se crianças e jovens de diferentes graduações de karaté revelavam alteração na CR e na variabilidade da frequência cardíaca (VFC), nas condições de imagética estática (I) e de execução...
Predicting climatic threats to an endangered freshwater mussel in Europe: The n...
da Silva, J.P.; Gonçalves, D.V.; Lopes-Lima, M.; Gama, M.; Miranda, R.; Reis, J.; Filipe, A.F.; Banha, F.; Sousa, R.The freshwater pearl mussel Margaritifera margaritifera has been suffering major population declines in Europe. This endangered species is a host specialist and exclusively requires salmonid species (Salmo trutta and Salmo salar) to complete its life cycle. In theory, obligatory biotic interactions should deserve special conservation attention, because the loss or massive decline of fish hosts may elicit the ex...

S.; Noites, R.Os oceanos contêm inúmeros habitats específicos diferentes, sendo necessário que os microrganismos desenvolvam diferentes mecanismos de adaptação para sobreviverem. Alguns destes são a produção de biomoléculas e enzimas específicas que lhes conferem propriedades antibacterianas, antifúngicas, antiinflamatórias, antiprotozoárias, antivirais, anticancerígenas, relevantes agentes infeciosos em endodontia. O objeti...
Multiple single cannulation technique of arteriovenous fistula: A randomized co...
Peralta, R.; Fazendeiro, J.; Pinto, B.; Gonçalves, P.; Sousa, R.; Félix, C.; Carvalho, H.; Vinhas, J.; Ponce, P.Introduction: Despite the impact needling has had on vascular access survival and patient outcome, there is no universal or standardized method proposed for proper cannulation. Rigorous studies are needed, examining cannulation practices, and challenges to achieving complication-free cannulation. Methods: This randomized, open-label trial was conducted at 18 dialysis units owned by a large private dialysis prov...
