Adherence of enteroaggregative Escherichia coli to the ileal and colonic mucosa...
Andrade,Jacy Alves Braga de; Freymüller,Edna; Fagundes-Neto,UlyssesCONTEXT: Enteroaggregative Escherichia coli strains have been associated with persistent diarrhea in several developing countries. In vivo procedures with animal models, in vitro assays with cellular lines and in vitro organ culture with intestinal fragments have been utilized to study these bacteria and their pathogenicity. OBJECTIVE: The present experimental research assessed the pathogenic interactions of th...
Pathophysiology of enteroaggregative Escherichia coli infection: an experimenta...
Andrade,Jacy Alves Braga de; Freymüller,Edna; Fagundes-Neto,UlyssesCONTEXT: Enteroaggregative Escherichia coli strains have been associated with persistent diarrhea in several developing countries. In vivo procedures with animal models as rat, rabbit and gnotobiotic piglets intestinal loops, in vitro assays with cellular lines like T84, Caco 2, HT29, HeLa e HEp-2 and in vitro organ culture with intestinal fragments have been applied to study these bacteria and their pathogenic...
Avaliação microscópica e ultra-estrutural do endotélio de veia safena preparada...
Silva,Virgílio Figueiredo; Ishigai,Márcia Marcelino de Souza; Freymüller,Edna; Branco,João Nelson Rodrigues; Gaia,Diego Felipe; Gabriel,Edmo AtiqueOBJETIVO: O enxerto de veia safena (VS) utilizado em revascularização miocárdica possui uma vida útil, sendo o estágio final a oclusão do vaso. Esforços em adquirir novas técnicas de coleta da VS podem possibilitar uma viabilidade maior do enxerto. MÉTODOS: Vinte pacientes foram randomizados e divididos em dois grupos com o objetivo de avaliação do endotélio vascular. A técnica "no touch" (NT) consiste em retir...
Active transcription and ultrastructural changes during Trypanosoma cruzi metac...
Ferreira,Ludmila R.P.; Dossin,Fernando de M.; Ramos,Thiago C.; Freymüller,Edna; Schenkman,SergioThe differentiation of proliferating epimastigote forms of Trypanosoma cruzi , the protozoan parasite that causes Chagas disease, into the infective and non-proliferating metacyclic forms can be reproduced in the laboratory by incubating the cells in a chemically-defined medium that mimics the urine of the insect vector. Epimastigotes have a spherical nucleus, a flagellum protruding from the middle of the prot...
