Gastroenterite aguda em crianças internadas na área de Lisboa
Escobar, C; Silva, T; Costa, B; Oliveira, M; Correia, P; Ferreira, G; Costa, I; Júlio, C; Rodrigues, J; Machado, J; Marques, A; Simões, MJ; Oleastro, MIntrodução: A Gastroenterite Aguda (GEA) é uma patologia com importante morbilidade sendo a segunda causa de internamento na idade pediátrica. Objetivo: Caracterizar a GEA, em crianças internadas em dois hospitais da área de Lisboa com diferentes características demográficas. Métodos: Estudo prospetivo de maio 2011 a junho 2012. Pesquisados potenciais agentes etiológicos por técnicas convencionais e de biologia...

Preditive factors of postoperative mortality after hepatic resection for hepato...
Recently, mortality associated with hepatic resection suffered a considerably reduction. To determine the prognostic factors of mortality after hepatic resection for hepatocellular carcinoma, a retrospective study of 69 cases operated between 1990 and 2008 was undertaken. Patients ́ mean age was 61,8 years-old and 93% were male. Chronic liver disease was present in 73% of cases. Mean Charlson’s Index and M.E.L....
Hydrogen effect on the sigma-phase in Fe53.8Cr46.2
Cieslak, J.; Costa, B. F. O.; Dubiel, S. M.; Fruchart, D.; Skryabina, N. E.Investigation of the stability and properties of a sigma-phase type compound Fe53.8Cr46.2 after electrochemical hydrogen treatment was made using X-ray diffraction and 57Fe Mössbauer spectroscopy techniques. The amount of the hydrogen uptake was estimated to be equal to ~1.2H per unit formula, and its presence leads to an anisotropic cell parameter expansion. However, the hydrogenated state appears as metastabl...

Mössbauer spectroscopy and X-ray diffraction studies of ball-milling-induced tr...
Costa, B. F. O.; Caër, G. Le; Malaman, B.; Batista, A. C.57Fe Mössbauer spectroscopy and X-ray diffraction were used to study the structural changes induced by ball milling a coarse-grained Fe48.1V51.9 at% sigma phase in a vibratory mill in argon with a frequent gas renewal. The sigma phase transforms into a bcc alpha phase till 140 h of milling. Mössbauer spectroscopy also shows the presence of an amorphous phase. Further, X-ray diffraction and Mössbauer spectroscop...
X-ray diffraction and Mössbauer spectrometry studies of molecular iron compounds
Costa, B. F. O.; Greneche, J. M.; Silva, M. Ramos; Pereira, L. C. J.We have synthesized two new iron complexes that have been structural and magnetically characterized: diphenylguanidinium hexafluoroferrate and hexakisvaline-oxo-triiron(III) chloride. The former crystallizes as monomers with the fluoride ions six-coordinating the Fe(II) ion. Valine iron chloride is comprised of trinuclear complexes, with a well ordered oxo-centered carboxylate core and some disordered organic l...
