Cytogenetic divergence between two sympatric species of Characidium (Teleostei, Characiformes, Crenuchidae) from the Machado River, Minas Gerais, Brazil Genet. Mol. Biol.
Silva,Alexandre Rodrigues da; Maistro,Edson Luis.
Cytogenetic studies were performed on two sympatric species of Characidium, C. gomesi and C. cf. zebra, from the Grande River basin, Minas Gerais State, Brazil. Although both species had a chromosome number of 50 with a karyotype exclusively consisting of meta- and submetacentric chromosomes, interspecific diversity was detected concerning the size of the two first chromosome pairs of the karyotypes. Active nucleolus organizer regions (NORs) were located at the terminal position on the long arm of the 17th pair of C. gomesi and at subterminal position on the long arm of the 23rd pair of C. cf. zebra. For both species the fluorochrome CMA3 stained only the NOR-bearing pair of chromosomes. The heterochromatin pattern also showed some differentiation between...

Respiratory syncytial virus rhinosinusitis in intensive care unit patients BJID
Silva,Alexandre Rodrigues da; Park,Marcelo; Boas,Lucy S. Vilas; Machado,Clarisse Martins.
This study reported a case of rhinosinusitis for Respiratory Syncytial Virus in Intensive Care Unit patient. The settings were Intensive Care Unit at Hospital das Clínicas, University of São Paulo Medical School, São Paulo, Brazil. One female HIV-infected patient with respiratory failure and circulatory shock due to splenic and renal abscesses, who developed rhinosinusitis caused by RSV and bacteria. Respiratory viruses can play a pathogenic role in airways infection allowing secondary bacterial overgrowth.
