Thromboembolic Complications During Endovascular Treatment of Ruptured Intracra...
Baptista, Tiago; Braz, Ana; Patrício, Madalena; Fragata, Isabel; Reis, JoãoThromboembolic phenomena are the most commonly reported complications during endovascular treatment of intracranial aneurysms with coils. Frequency of this complication varies in the literature, but authors reported rates ranging from 2.5 to 28%. Several mechanisms may be involved in the formation and migration of thrombus: it may be already existing inside the aneurysm and be dislocated and then migrate distal...
Fracture process characterization of fiber-reinforced dental composites evaluat...
Matheus,Tibério C. U.; Kauffman,Cynthia M. F.; Braz,Ana K. S.; Mota,Cláudia C. B. O.; Gomes,Anderson S. L.This study used optical coherence tomography (OCT) compared to scanning electron microscopy (SEM) and optical microscopy (OM) to evaluate qualitatively crack propagation and final fracture in restorative composite materials - Filtek Z250 and Filtek Z350 (3M ESPE) - with fiber reinforcement after cyclic loading. Samples were made using a split mold. Initially, 3-point bending tests were performed to determine th...
Comparação de métodos de identificação de bactérias floculentas presentes em ETAR
Braz, Ana Inês de Matos DomingosDissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para obtenção do grau de Mestre em Engenharia do Ambiente – Perfil Engenharia Sanitária ; “A unidade operacional básica de um sistema de lamas activadas é o floco” (Gray, 2004). Quando a lama e a água residual são misturadas, há uma rápida aglomeração da matéria suspensa e coloidal em flocos, que irá provocar uma queda...
Influence of water storage time on the bond strength of etch-and-rinse and self...
Dantas,Darlene Cristina Ramos Eloy; Ribeiro,Ana Isabella Arruda Meira; Lima,Lúcia Helena Marques de Almeida; Lima,Marcelino Guedes deThe purpose of this study was to evaluate comparatively the shear bond strength (SBS) of etch-and-rinse (Adper Scotch Bond Multi Purpose - ASBMP and Adper Single Bond 2 - ASB2) and self-etching (AdheSe -AD and Adper Prompt - AP) adhesive systems after short- and long-term water storage. Eighty bovine teeth were randomly assigned to 4 groups (n=20, 10 teeth for 24 h and 10 for 6 months). After surface treatment,...
Origem e significado do amor na mitologia greco-romana
Braz,Ana Lúcia NogueiraO presente artigo visou compreender as possíveis origens e o significado do amor, utilizando como referência de análise a mitologia greco-romana. A escolha da abordagem mitológica justifica-se pelo fato de que, em nossa pesquisa, encontramos na cosmologia greco-romana uma das primeiras formulações e significado do amor através do mito de Eros e suas diversas repercussões. Utilizou-se dele para tornar mais claro...
Cytogenetic study of Brazilian patients with myelodysplastic syndrome (MDS)
Borgonovo,Tamara; Ribeiro,Enilze M.S.F.; Cornélio,Déborah Afonso; Schmid-Braz,Ana Teresa; Jamur,Valderez Ravaglio; Wuicik,LismeriBone marrow cytogenetic studies were performed on 93 patients with primary myelodysplastic syndrome (MDS) diagnosed at the Clinical Hospital of the Federal University of Paraná, Brazil. Chromosomal alterations were observed in 69% of the patients. Monosomy of chromosome 7, deletions of 7q, 5q, 12p and 20q, rearrangements of 11q23 and trisomies of chromosomes 8 and 21 were the most frequent abnormalities observe...
Arachnoiditis ossificans.
Braz, Ana; Gonçalves, Cristina; Diogo, Correia; Reis, Fernando CostaArachnoiditis ossificans is a uncommon disorder, is generally associated with neurologic deficits, but patients could be only mild sintomatic, regardless of the degree of ossification. Unenhanced CT has been well show to be sensitive for the disorder, useful to evaluate the full extenstion of the ossified mass and their remotion if surgical intervention is needed. On MRI imaging the manifestations could be mini...
