    摘要: Implant devices and cutting clamp apparatuses and methods for creating the implants for insertion into a patient's joint to restore anatomic length and assist in final positioning of the bones following removal of cartilage and/or bone in preparation for fusion. A first implant is a biplanar implant having a shape to mimic the normal anatomical shape of the bones the implant is configured to mate with. The first implant may be cut using a cutting clamp and jig having the anatomical shape of the bones the implant will be inserted within or between. A second implant is a cylindrical piece of bone having a convex end and a concave end for mating with bones reamed to have the opposite mating surfaces. The second implant is created using cup and cone reamers having dimensions corresponding to the size of the patient's bones. Surgical methods for inserting the implants within a patient.

    摘要: The present invention provides double-stranded RNA molecules that mediate RNA interference in target cells, preferably hepatic cells. The invention also provides double-stranded RNA (dsRNA) molecules that are modified to be resistant to nuclease degradation, which inactivates a virus, and more specifically, hepatitis C virus (HCV). The invention also provides a method of using these modified RNA molecules to inactivate virus in mammalian cells and a method of making modified small interfering RNAs (siRNAs) using human Dicer. The invention provides modified RNA molecules that are modified to include a dsRNA or siRNA wherein one or more of the pyrimidines in the RNA molecule are modified to include 2′-Fluorine. The invention also provides dsRNA or siRNA in which all pyrimidines are modified to include a 2′-Fluorine. The invention provides that the 2′-Fluorine dsRNA or siRNA molecule is further modified to include a two base deoxynucleotide “TT” sequence at the 3′ end of the molecule.
