Is Anti-Hepatitis C Virus Antibody Level an Appropriate Marker to Preclude the Need for Supplemental Testing.

abstract：BACKGROUND:We have recently demonstrated that an oligodeoxynucleotide (ODN) can enter HIV particles and form a local hybrid at the highly conserved polypurine tract (PPT), the target site of the ODN. This hybrid is recognized by the retrovirus-specific RNase H, which is a virion-associated enzyme. It cleaves the RNA at...
