In situ hybridization was performed using cRNA probes on human liver biopsies to localize both positive and negative RNA strands of hepatitis C virus. From the 5' non-coding region of the viral genome, 210 bp, were amplified by reverse transcriptase-polymerase chain reaction and cloned in a plasmid. Probes were produced by in vitro transcription, and(More)
A novel acylpeptide hydrolase, named APEH-3(Ss), was isolated from the hypertermophilic archaeon Sulfolobus solfataricus. APEH is a member of the prolyl oligopeptidase family which catalyzes the removal of acetylated amino acid residues from the N terminus of oligopeptides. The purified enzyme shows a homotrimeric structure, unique among the associate(More)
OBJECTIVE To assess the prognostic significance of atypical squamous cells of undetermined significance (ASCUS) using an in situ hybridization (ISH) method for destined cervical cytologic smears and a cocktail of biotinylated DNA probes for human papillomavirus (HPV) 6, 11, 16, 18, 31 and 33. STUDY DESIGN Two HPV DNA probe mixtures were applied to the(More)
