Assessing the impact of introduced cats on island biodiversity by combining die...
Hervias, s; Oppel, S.; Medina, F.M.; Pipa, T.; Diez, A.; Ramos, J.A.; Ruiz de Ybanez, R.; Nogales, M.Populations of feral (not owned by humans) and domestic cats Felis catus coexist in most inhabited islands, and they have similar impacts on native species. Feral cats are generally believed to vary their diet according to prey availability; however, no previous studies of diet have tested this hypothesis on insular ecosystems with a limited range of available prey. Because domestic cats kill prey independently...
The influence of sulfathiazole on the macroalgae Ulva lactuca
Leston, Sara; Nunes, Margarida; Viegas, Ivan; Nebot, Carolina; Cepeda, Alberto; Pardal, M. A.; Ramos, FernandoSulfonamides (SA) are a class of antibiotics routinely found in environmental matrices and therefore their role as contaminants should be investigated in non-target organisms. With this purpose the present experimental work has evaluated the exposure of the chlorophycean Ulva lactuca L. to sulfathiazole (STZ), a SA drug commonly used in aquaculture, at two concentrations representing prophylactic (25 lgmL 1) an...
Ablação Septal Alcoólica no Tratamento da Cardiomiopatia Hipertrófica Obstrutiv...
Fiarresga, A; Cacela, D; Galrinho, A; Ramos, R; Sousa, L; Bernardes, L; Patrício, L; Cruz Ferreira, RIntrodução: A ablação septal alcoólica (ASA) é a forma percutânea de tratamento invasivo da cardiomiopatia hipertrófica obstrutiva (CMHO). A propósito da descrição da experiência no nosso centro, procurar-se-á rever as indicações, os aspetos técnicos e práticos e os resultados da ASA, assim como a sua posição atual em comparação com a miectomia cirúrgica.Objetivo: Avaliar os resultados da ASA numa série de doen...

Improving the study of proton transfers between amino acid sidechains in soluti...
Silva, Pedro J.; Perez, Marta A. S.; Brás, Natércia F.; Fernandes, Pedro A.; Ramos, Maria JoãoWe have studied the influence of implicit solvent models, inclusion of explicit water molecules, inclusion of vibrational effects, and density functionals on the quality of the predicted pK a of small amino acid side chain models. We found that the inclusion of vibrational effects and explicit water molecules is crucial to improve the correlation between the computed and the experimental values. In these micro-...
The activity of flavones and oleanolic acid from Lippia lacunosa against suscep...
Castellar,Aline; Coelho,Tatiane S.; Silva,Pedro E. A.; Ramos,Daniela F.; Lourenço,Maria Cristina S.; Lage,Celso L. S.; Julião,Lisieux S.Tuberculosis (TB), caused by Mycobacterium tuberculosis, is the world's number one killer among infectious diseases. The search for new naturalproducts that can act as drugs against TB has received increased attention duringthe last years. In this work we describe the isolation and identification of the active antimycobacterial principles of the dichloromethane extract from Lippia lacunosa Mart. & Schauer, ...
Prognostic Value of a New Cardiopulmonary Exercise Testing Parameter in Chronic...
Toste, A; Soares, R; Feliciano, J; Andreozzi, V; Silva, S; Abreu, A; Ramos, R; Santos, N; Ferreira, ML; Cruz Ferreira, RINTRODUCTION: A growing body of evidence shows the prognostic value of oxygen uptake efficiency slope (OUES), a cardiopulmonary exercise test (CPET) parameter derived from the logarithmic relationship between O(2) consumption (VO(2)) and minute ventilation (VE) in patients with chronic heart failure (CHF). OBJECTIVE: To evaluate the prognostic value of a new CPET parameter - peak oxygen uptake efficiency (POUE...
Incidência de Arritmias Ventriculares em Doentes com Disfunção Sistólica Ventri...
Timóteo, AT; Oliveira, MM; Nogueira da Silva, M; Toste, A; Ramos, R; Feliciano, J; Cunha, PS; Soares, R; Santos, S; Cruz Ferreira, RIntrodução: A terapêutica de ressincronização cardíaca (TRC) tem benefícios significativos em doentes seleccionados. O impacto desta modalidade na incidência de taquidisritmias ventriculares permanece controverso. Analisámos a ocorrência de terapêuticas apropriadas em doentes submetidos a TRC combinada com cardioversor-desfibrilhador (CDI). Métodos: Estudo de 123 doentes com fracção de ejecção ventricular esque...
Yeast diversity related with Touriga Nacional Grape variety
Duarte, Filomena; Teixeira, A.; Ramos, P.; Gomes, Ana Catarina; Schuller, Dorit; Alemão, F.; Costa, Ana Catarina Moreira daThe diversity of yeast species related with the grape variety Touriga Nacional was evaluated at four distinct vineyards of three Portuguese wine regions. Samples were collected 48 h after crushing, and when the loss of CO2 reached 70 g/L. Restriction profiles analysis of 26S rDNA region with the endonucleases HaeIII, CfoI, HinfI, ApaI and MseI was used to characterize the five hundred and nine isolates obtained...
A microscopy study of germanium nanoparticules produced by pulsed laser deposition
Martín-Sánchez, J.; Marques, L.; Pinto, S. R. C.; Vieira, E. M. F.; Rolo, Anabela G.; Chahboun, A.; Ramos, Marta M. D.; Gomes, M. J. M.Comunicação oral ; Semiconductor nanoparticles (NPs) are of great interest for multiple applications in the fields of photonics, optoelectronics, photovoltaics and biomedicine [1]. The ability to manage properly the size distribution and density in the fabrication process is of crucial relevance. In the literature, it can be found a large number of strategies for NPs production, including physical vapour depos...
