A population of Aedes albopictus collected in 1986 in Harris County, Texas, was evaluated for its vector competence with 4 California serogroup viruses (Jamestown Canyon, Keystone, La Crosse and trivittatus). Rates of midgut infection, dissemination of virus beyond the midgut and oral transmission to suckling mice were markedly different for the 4 viruses(More)
Twenty isolates of Jamestown Canyon virus were obtained from adult females of 5 Aedes species collected at the Houghton Lake Wildlife Research Area, Missaukee County, in north-central Michigan between 1985 and 1989. Fourteen were from Aedes provocans, and 6 were from 4 other snowmelt Aedes species. One isolate of trivittatus virus and one Cache Valley-like(More)
OBJECTIVE To investigate oxidative DNA damage in pharmacy technicians preparing antineoplastic drugs at the PIVAS (Pharmacy Intravenous Admixture Service) in two Chinese hospitals. METHODS Urinary 8-OHdG served as a biomarker. 5-Fluorouracil (5-FU) concentrations in air, masks and gloves were determined. The spill exposure of each PIVAS technician to(More)
The ability of 14 species of mosquitoes to biologically transmit Jamestown Canyon virus was tested. Four species not previously described as vectors of that virus transmitted to suckling mice. Among membrane-fed mosquitoes with disseminated infections, field-collected Aedes canadensis (1/3), Anopheles punctipennis (1/12), Coquillettidia perturbans (2/14)(More)
Emergencies of epistaxis in students caused by environmental pollution have rarely been reported to date. This study aimed to explore the cause of an emergency of epistaxis in elementary students by using a field epidemiological investigation. Twenty-two epistaxis cases from a single school with differences in gender, age, and classroom, were diagnosed(More)
