13. Evaluation of HA negatively charged membranes in the recovery of human adenoviruses and hepatitis A virus in different water matrices
Human adenoviruses (HAdV) and hepatitis A virus (HAV) are shed in the faeces and consequently may be present in environmental waters, resulting in an increase in pathogen concentration that can affect water quality and human health. The aim of this study was to evaluate an adsorption-elution method which utilizes negatively charged membrane HA to determine t

14. Variabilidade genética de adenovírus humano da espécie B, associados a casos de infecção respiratória aguda, em São Paulo, de 1995 a 2006 / Genetic variability of human adenoviruses species B associated to acute respiratory disease in children from São Paulo, Brazil, from 1995 to 2006
Adenovirus humanos são responsáveis por infecção respiratória aguda (IRA) em crianças e adultos, sendo os das espécies B e C mais frequêntes. Com o objetivo de estudar a variabilidade genética de HAdVs, 3087 amostras de aspirado de nasofaringe foram colhidas de crianças, em São Paulo, de 1995 à 2006. A PCR direcionada ao gene VA-RNA detectou 677

15. Adenoviruses C in non-hospitalized Mexican children older than five years of age with acute respiratory infection
Adenoviruses (AdV) are commonly involved in acute respiratory infections (ARI), which cause high morbidity and mortality in children. AdV are grouped in six species (A-F), which are associated with a wide range of diseases. The aim of this study was to identify the AdV species infecting non-hospitalized Mexican children with ARI symptoms, attending to the sa

16. Pesquisa de vírus entéricos humanos em lodos de esgoto originários de duas ETEs do Estado de São Paulo: estabelecimento e avaliação de metodologia para recuperação e detecção viral. / Detection of human enteric viruses in sewage sludge from two sewage treatment plants in São Paulo state: establishment and evaluation of a method for viral recovery and detection.
O objetivo foi desenvolver e avaliar uma metodologia simplificada para detecção de vírus entéricos humanos em lodo de esgoto. O método foi baseado em eluição viral com solução protéica, seguida de ultracentrifugação. Alguns parâmetros foram avaliados (tempo e pH de eluição, condições de clarificação e purificação). A seguir, foi aplicado

17. Human adenovírus serotype 41 interaction with hematopoietic cells: cellular permissiviness and viral gene expression analysis. / Interação do adenovírus humano, sorotipo 41, com células origem hematopoiética: análise da permissividade celular e da expressão gênica viral.
In order to verify the permissiveness of hematopoietic cells to HAdV-41 infection, PBMC and IEL from volunteers were infected. The infection assays were compared with infected HEK -293 cells. We analysed the E1A, E1B (55K), E3 (14K), VARNA, hexon and short fiber (SF) viral gene expression and GAPDH cellular gene expression. The mRNA were detected by real tim

18. Antigenic and genomic characterization of adenovirus associated to respiratory infections in children living in Northeast Brazil
From January to December 1998, nasopharyngeal aspirates were obtained from 482 children with acute respiratory infections attended in emergence department and wards of a teaching hospital in the city of Salvador, Brazil. The samples were tested for the presence of adenovirus by isolation in tissue culture and indirect immunofluorescence assay. Eleven adenovi

19. Clinical and epidemiologic profile of acute respiratory infections caused by adenovirus in children attended in reference hospital in the city of Fortaleza - CE / Perfil clÃnico-epidemiolÃgico de InfecÃÃes respiratÃrias agudas causadas por adenovÃrus em crianÃas atendidas em hospital de referÃncia da cidade de Fortaleza - CE
Adenoviruses (Ad) are important etiological agents of acute respiratory infections (ARI) in children, particularly between six months and five years old. This was a retrospective study, whose objectives were: to perform clinical and epidemiologic profile of adenoviral respiratory infections in children attended in Hospital Infantil Albert Sabin, in the city

20. Adenoviruses as biological indicators in watewater from sewage, before anaerobic process treatment and soil disposal / Adenovirus e rotavirus como indicadores biologicos em aguas residuarias de esgotos sanitarios apos tratamento por processo anaerobio e disposição controlada no solo
O tratamento de esgoto sanitário em lagoa de decantação anaeróbia e disposição controlada de água residuária no solo é uma alternativa de baixo custo para o reuso de águas residuárias na agricultura. Nele, o esgoto sanitário é depositado em uma lagoa de decantação anaeróbia com retenção hidráulica de sete dias, após o que a água residuá

21. Desenvolvimento de um modelo de vacinação contra Toxoplasma gondii empregando adenovírus recombinante
In the present study, genes encoding the SAG1, SAG2 and SAG3 proteins of T. gondii were cloned into replication-deficient recombinant adenoviruses, after being modified for appropriate expression in mammalian cells. Modifications included removal of 3-end sequences encoding the GPI-anchoring motifs and, for SAG3, substitution of the 5´-end encoding the natu

22. Isolation and identification of Adenovirus in hospitalized children, under five years, with acute respiratory disease, in Havana, Cuba
Nine Adenovirus (Ad) strains isolated in Cuba, from 128 nasopharingeal swab specimens of children below five years old, with acute respiratory diseases, during 1996 and 1997, were studied by restriction enzyme analysis of genomic DNA with two endonucleases BamH I and Sma I. All different fragment patterns were compared with the respective prototypes. The ide

23. Estudo farmacolÃgico da ternatina, um flavonÃide isolado de Egletes viscosa, LESS / FarmacolÃgico study of the ternatina, an isolated flavonÃide of Egletes viscose, LESS
Ternatin (5, 4â-dihydroxy-3, 7, 8, 3â-tetrametoxy-flavone), a flavonoid which was extracted and purified from Egletes viscosa, Less. (Compositae), was screened for various pharmacological effects in experimental animals. The compound (15 and 30 mg/kg, i.p.) demonstrated a dose-related significant anti- inflammatory effect in the carrageenan-induced rat hin

24. Detection and Analysis of Six Lizard Adenoviruses by Consensus Primer PCR Provides Further Evidence of a Reptilian Origin for the Atadenoviruses
A consensus nested-PCR method was designed for investigation of the DNA polymerase gene of adenoviruses. Gene fragments were amplified and sequenced from six novel adenoviruses from seven lizard species, including four species from which adenoviruses had not previously been reported. Host species included Gila monster, leopard gecko, fat-tail gecko, blue-ton
