Translation of hepatitis C virus (HCV) and classical swine fever virus (CSFV) RNAs is initiated by cap-independent attachment (internal entry) of ribosomes to the approximately 350-nucleotide internal ribosomal entry segment (IRES) at the 5' end of both RNAs. Eukaryotic initiation factor 3 (eIF3)
The lengthy 5' noncoding region (5' NCR) of hepatitis C virus (HCV) RNA forms a highly ordered secondary structure, very conserved among different strains. It includes an internal ribosome entry site (IRES) element, responsible for the cap-independent translation initiation of HCV RNA. Similarly to
Hepatitis C virus (HCV) is classified in the genus Hepacivirus of the family Flaviviridae, whose members have a single-stranded RNA genome of positive polarity, which encodes a single polyprotein. Within this family, HCV is closely related to viruses of the genus Pestivirus, which includes classical
We report a case of Q fever-related antiphospholipid syndrome in a patient presenting with acalculous cholecystitis and pneumonia. Serial laboratory tests indicated that the previous serological tests suggesting hepatitis C virus and Mycoplasma pneumoniae infections were false-positives. The
For Argentine Hemorrhagic Fever, a disease caused by Junin virus (JV), there is an effective treatment, consisting of the transfusion of immune plasma (IP). This plasma is obtained from individuals who have had the disease. Since Hepatitis C virus (HCV) is transmitted parenterally, this study was
BACKGROUND
Familial Mediterranean fever is an autosomal recessive disorder characterized by periodic febrile attacks of aseptic serositis and/or arthritis. The main treatment is colchicine which prevents attacks in the majority of patients except for a group of colchicine-resistant cases. Chronic
Monotherapy of hepatitis C virus infection with either alpha interferon or ribavirin alone is rather ineffective, while the use of the two antivirals together is much more efficacious. In vitro drug-drug combination analysis utilizing related members of the family Flaviviridae, bovine viral diarrhea
Hepatitis C virus (HCV) is a recently described causative agent of the great majority of post-transfusion non A-non B hepatitis and is classified within the Flaviviridae family. Due to a high prevalence of anti-HCV and other flaviviruses circulating in Brazil, such as dengue and yellow fever, we
The serum phospholipid (PL) profiles of healthy volunteers (HE) and patients with recently diagnosed dengue fever (DF), hepatitis B (HBV), and hepatitis C (HCV) were investigated using liquid chromatography-ion trap-mass spectrometry (LC-IT-MS) and liquid chromatography-triple quad-mass spectrometry
Initiation of translation of hepatitis C virus and classical swine fever virus mRNAs results from internal ribosomal entry. We reconstituted internal ribosomal entry in vitro from purified translation components and monitored assembly of 48S ribosomal preinitiation complexes by toe-printing.
Hepatitis C virus (HCV) and classical swine fever virus (CSFV) are important pathogens for which new therapeutic approaches are in high demand. Herein, we report the synthesis of newly designed thioglycosyl analogs of glycosyltransferase substrates which were evaluated using cell-based assays for
Chimeric yellow fever virus (YF) RNAs were constructed in which the YF structural genes were replaced by the hepatitis C virus (HCV) structural genes or fusions between the YF and HCV structural genes. Interestingly, RNA replication required nucleotide complementarity between the 3'-located
Acute C hepatitis, compared with hepatitis A or B, may sometimes be associated with extrahepatic manifestations of a haematologic nature. The first case of hepatitis associated with aplastic anemia was reported by Lorenz in 1955. We observed a patient who developed acute hepatitis, associated with
OBJECTIVE
Since acute hepatitis C virus (HCV) infection is often asymptomatic, it is difficult to examine the rate and determinants of spontaneous clearance. Consequently, these studies are subject to bias, which can potentially lead to biased rates of viral clearance and risk estimates. We
