TT virus (TTV) has a wide range of sequence divergence by which it is classified into at least 16 genotypes. A TTV isolate of genotype 12 (TJNO1) and another of genotype 13 (TJN02) were sequenced in the entire genome, and compared with the reported T

We have proposed that hepatitis C virus should be classified into eleven genetic groups (types) which further divide into more than 80 genotypes (subtypes). However, only eight genetic groups (1-6, 10 and 11) have been defined on the basis of the ful

Publikováno v: Hepatology Research. 10:1-16

The genomic DNA of a novel virus named TT virus (TTV), associated with posttransfusion hepatitis of unknown etiology, was cloned from plasma of a blood donor with an elevated transaminase level but without serological markers of known hepatitis virus

Publikováno v: Journal of the Japan Society of Blood Transfusion. 44:693-696

A new hepatitis-associated virus, hepatitis G virus (HGV), has been reported. Although its epidemiology, mode of transmission, and infectiousness are not yet well understood, it may be transmitted by transfusion. We investigated the transmission of H

Publikováno v: Journal of General Virology. 75:629-635

Three hepatitis C virus (HCV) isolates were obtained from patients with chronic liver diseases in Indonesia which were not classifiable into any of the genotypes I/1a, II/1b, III/2a, IV/2b or V/3a reported previously. The entire nucleotide sequence w

In November 1989, Japanese Red Cross Blood Centres started screening for hepatitis C virus (HCV) with enzyme-linked immunosorbent assay (Elisa) for the C100-3 viral peptide as the first such nationwide programme in the world. Thereafter post-transfus

Either parts or multiple copies of the core gene of hepatitis C virus (HCV) were fused to the 3' terminus of the hepatitis B virus (HBV) core gene with 34 codons removed. As many as four copies of HCV core protein (720 amino acids) were fused to the

Publikováno v: Applied optics. 35(19)

A proposed method of secondary phase modulation for open-loop fiber-optic gyroscopes is examined in general terms. To detect the rotation rate of a system through a beat-frequency channel, we employ linearly combined signals with different frequencie
