Persistence or clearance of human papillomavirus infections in women in Ouro Pr...
Miranda, Priscila Mayrink de; Silva, Nayara Nascimento Toledo; Pitol, Bruna Caroline Vieira; Silva, Ismael Dale Cotrim Guerreiro daPersistent high-risk (HR) human papillomavirus (HPV) infection is necessary for development of precursor lesions and cervical cancer.We investigate persistence and clearance of HPV infections and cofactors in unvaccinated women. Cervical samples of 569 women (18–75 years), received for routine evaluation in the Health Department of Ouro Preto, Brazil, were collected and subjected to PCR (MY09/11 orGP5+/6+ prime...

Quality evaluation of simvastatin compounded capsules.
Marinho, Flávia Dias Marques; Zanon, José Carlos da Costa; Sakurai, Emília; Reis, Ilka Afonso; Lima, Angélica Alves; Soares, Cristina Duarte ViannaNo Brasil, a sinvastatina está comercialmente disponível na forma de comprimidos e cápsulas manipuladas. Poucos relatos estão disponíveis sobre a qualidade e, consequentemente, a eficácia dessas cápsulas. A qualidade de 30 lotes de sinvastatina 20 mg cápsulas do mercado foi avaliada através da determinação de peso, uniformidade de conteúdo, desintegração (Farmacopéia Brasileira), doseamento e teste de dissoluçã...
Human papillomavirus infection in Brazilian women with normal cervical cytology.
Miranda, Priscila Mayrink de; Pitol, Bruna Caroline Vieira; Moran, M. S.; Silva, N. N. T.; Felix, P. M.; Lima Filho, José Luiz deWe examined the prevalence of human papillomavirus (HPV) infection in a sample of Brazilian women presenting normal cervical cytology. Possible interactions between patient characteristics and HPV infection were analyzed in order to provide background data to improve cervical cancer screening and prophylaxis. Cervical samples of 399 women, received for routine evaluation in the Health Department of Ouro Preto, ...
Can established cultured papilloma cells harbor bovine papillomavirus?
Campos, Sérgio Roberto de Souza Leão da Costa; Trinidade, C.; Ferraz, Oilita Pereira; Silva, Dalton Giovanni Nogueira da; Lima, Angélica AlvesPapillomaviruses have been reported to be very dif¬ficult to grow in cell culture. Also, there are no descriptions of cell cultures from lesions of bovine cutaneous papillomatosis, with identification of different bovine papilloma virus (BPV) DNA se¬quences. In the present report, we describe primary cell cultures from samples of cutaneous lesions (warts). We investigated the si¬multaneous presence of different...
Simvastatin assay and dissolution studies by feasible rp-hplc in tablets.
Marinho, Flávia Dias Marques; Santos, Amanda Leão dos; Soares, Cristina Duarte Vianna; Reis, Ilka Afonso; Zanon, José Carlos da CostaCommonly used HPLC acetonitrile solvent has been through a worldwide shortage with a cost increase in 2008 and 2009. In order to get around this situation, a method by RP-HPLC employing methanol and aqueous acid mobile phase was developed and validated to evaluate simvastatin. The quality control assay and dissolution studies of this lipid-lowering drug were performed in diluents methanol and 0.01 M phosphate b...

Self-similarities of periodic structures for a discrete model of a two-gene sys...
Souza, Silvio Luiz Thomaz de; Lima, Angélica Alves; Caldas, Iberê Luiz; Torricos, Rene Orlando Medrano; Guimarães Filho, Zwinglio de OliveiraWe report self-similar properties of periodic structures remarkably organized in the two-parameter space for a two-gene system, described by two-dimensional symmetric map. The map consists of difference equations derived from the chemical reactions for gene expression and regulation. We characterize the system by using Lyapunov exponents and isoperiodic diagrams identifying periodic windows, denominated Arnold ...
Apolipoprotein e polymorphism in Brazilian dyslipidemic individuals : Ouro Pret...
Lana, Angelo Mendes; Pena, Geórgia das Graças; Freitas, Silvia Nascimento de; Lima, Angélica Alves; Nicolato, Roney Luiz de CarvalhoThe influence of apolipoprotein E alleles and genotypes on plasma lipid levels was determined in 185 individuals of mixed ethnicity living in Ouro Preto, Brazil. DNA was obtained from blood samples and the genotypes were determined by an RFLP-PCR procedure. The *3 allele was the most frequent (72%), followed by *4 (20%) and *2 (8%); *4 frequency was higher and *2 frequency was lower in the dyslipidemic group th...
