Abstract: Hammerhead ribozymes that target components critical to HSV replication (ICP4, UL20, UL30, and UL54) were synthesized and shown to efficiently cleave target RNA encoding a portion of these components in in vitro assays. Several cloned cell lines stably expressing these ribozymes were established. HSV-mediated plaque formation was dramatically reduced in cells stably transfected with an anti-HSV ribozyme compared to non-transfected cells.

Abstract: A sound damping composition which includes a plasticizer and at least one unsaturated block copolymer having a mono alkenyl arene content of equal to or greater than 60 weight percent and a modulus of less than 125,000 psi.
