In 3 laboratory experiments, mosquitoes were fed hepatitis C virus (HCV)-RNA positive blood by using membrane feeders, separated into head, thorax, and abdomen, and tested by a reverse transcriptase polymerase chain reaction for HCV-RNA. HCV did not replicate or disseminate in mosquitoes that had ingested blood from patients that were HCV-viremic positive.(More)
UNLABELLED Since the advent of anti-hepatitis C virus (HCV)-testing, the current worldwide prevalence of cryptogenic cirrhosis is essentially unknown. OBJECTIVES 1) determine if serum HCV RNA testing by the polymerase chain reaction (PCR) enhances the diagnostic yield for HCV in patients with anti-HCV-negative cryptogenic liver disease and 2) further(More)
OBJECTIVES To further determine potential routes of sexual transmission of hepatitis C virus (HCV), we examined the menstrual blood of women chronically infected with this virus. METHODS Ten premenopausal women with documented HCV infection were studied. All patients were anti-HCV positive by ELISA-II and positive for HCV RNA by polymerase chain reaction.(More)
Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. Measurements of the Power Spectrum and Redshift Distortions of the Las Campanas Redshift Survey Thesis directed by Professor Andrew Hamilton I(More)
We report on the results of our monitoring program of SNR 1987A with the Chandra X-Ray Observatory. The high resolution images and the spectra from the latest Chandra data suggest that the blast wave has reached the dense inner ring in the western side of the SNR, as well as in the east. The observed soft X-ray flux is increasing more rapidly than ever, and(More)
We continue monitoring supernova remnant (SNR) 1987A with the Chandra Xray Observatory. As of 2004 January, bright X-ray spots in the northwest and the southwest are now evident in addition to the bright eastern ring. The overall Xray spectrum, Since 2002 December, can be described by a planar shock with an electron temperature of ∼2.1 keV. The soft X-ray(More)
