Hepatitis G viral (HGV) infection among northeastern Thai blood donors was determined by the nested RT-PCR technique. HGV RNA was amplified by the degenerated helicase primers for a product of the expected size of 83 base pairs were used in this study. Serum samples from 322 of three different categories of northeastern Thai blood donors were included in this study. There were 104 HBsAg and Ant...

A molecular epidemiological study was performed to investigate the prevalence of GB virus C/hepatitis G virus (GBV-C/HGV) infection among various populations in Surabaya, Indonesia. The prevalence of GBV-C/HGV RNA, determined by reverse transcription-PCR for a portion of the NS3 region of the viral genome, was 2.7% (4 of 150) among randomly collected blood donor sera, which were all negative fo...

To investigate which subsets of peripheral blood mononuclear cells (PBMCs) are susceptible to infection with hepatitis C virus (HCV) and hepatitis G virus (HGV) or GB virus C (GBV-C), a PCR-based assay using tagged primers in the core region (HCV) and NS3 region (HGV/GBV-C) for the specific detection of negative strand (replicating) viral RNA sequences was developed. In liver biopsy samples bot...

GB vims-C (GBV-C)仇epatitis G vims (HGV) is a positive, single-strand RNA virus that has been classified in the family Flaviviridae. Interestlngly, GBVIC/HGV appears to have a truncated or absent core protein at the amino teminus of the polyprotein. GBV-C/HGV is transmitted parenterally and probably sexually. Most GBV-C作iGV infections appear to be asymptomatiC, persistent, and no correlation bet...

The aim of the present study was to evaluate the prevalence of HEV, TTV and GBV-C/GBV-C/HGV in patients with acute viral hepatitis A, B and non-A-C. We evaluated sera of 94 patients from a sentinel program who had acute hepatitis A (N = 40), B (N = 42) and non-A-C (N = 12); 71 blood donors served as controls. IgM and anti-HEV IgG antibodies were detected by enzyme immunoassay using commercial k...

The prevalence, incidence, clinical features, and natural history of hepatitis G virus (HGV) or GB virus C (GBV-C) were investigated in a non-remunerated blood donor population to determine its clinical significance and its impact on blood safety. Of 1020 regular blood donors, 23 (2.25%) were positive for plasma HGV/GBV-C RNA. Alanine aminotransferase levels were lower than in uninfected donors...

Hepatitis G virus (HGV) was recently identified as a new member of the Flaviviridae, but its clinical significance is still unclear. Since no immunoassay for the diagnosis of HGV is available, we developed a sensitive reverse transcription-PCR (RT-PCR) assay to facilitate the detection of the viral genome by mass screening in the clinical laboratory. Sequences within the 5'-noncoding region and...

background and aims: viral hepatitis is a global health problem with a high mortality rate. recently, a new flavi-like virus, provisionally named hepatitis g virus (hgv), has been described. hgv does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (pc...

The replication sites of the recently discovered hepatitis G virus (HGV) remain unknown. Using highly strand-specific Tth-based reverse transcriptase PCR, we searched for the presence of viral RNA negative strand in multiple autopsy tissues from four patients with AIDS and in peripheral blood mononuclear cells from six other human immunodeficiency virus-positive patients. Negative-strand HGV RN...

Secreted phospholipases A2 (sPLA2s) are extracellular enzymes that catalyze the release of free fatty acids and lysophospholipids from membrane phospholipids and also bind to different receptors (e.g., PLA2R1 or integrins). To date, 12 mammalian sPLA2s have been identified, which play a critical role in pathophysiological processes including inflammation and cancer. sPLA2s activate immune cells...
