Title: Recombinant vectors derived from adenovirus for use in gene therapy
Inventor: BOUT ABRAHAM
IPC: C07H21/04
Filed: 1995-08-15
Abstract: The invention provides novel vectors derived from adenovirus which are specifically suitable for use in methods of gene therapy.  The vectors have a deletion compared to wild-type adenovirus in that the E1 region is not present in a functional manner.  Additionally  the vectors are characterized in that they do contain a part of the E3 region of adenovirus which is biologically functional.  This results in vectors which do normally not lead to expression of adenoviral proteins, but which in the cases where such proteins do become expressed will repress the host's immunological response to said proteins.  Thereby host cells infected (provided) with the vector will live longer.  Therefore, the product introduced into said cells providing the therapy will be produced in larger amounts, or at least for a prolonged period.  Preferably the vector comprises genetic information for antisense therapy, or for genes which will combat tumors, such as genes encoding cytokines, preferably IL-1, or so called suicide genes, such as Herpes Simplex Virus thymidine kinase.  Methods for producing said vectors and methods of gene therapy or uses therein are also disclosed.

Title: Snap-Together Wall Plates for Ganged Electrical Device Installations
Inventor: HUFF BOB E
IPC: H02G3/08
Filed: 1996-04-17
Abstract: A wall plate for snap-fit engagement with an identical wall plate on one or both sides to provide an assembly of side-by-side plates for use with a ganged installation of electrical wiring devices.  The plate is rectangular with a rearwardly extending flange, including a pair of side  walls  having  inner  and  outer  surfaces,  extending  about  its periphery.  A U-shaped tab, having a medial portion including a linear-edged shoulder parallel to and spaced from the adjacent side wall, extends  outwardly  from  the  outer  surface  of  each  side  wall.   A rectangular opening in each side wall is positioned laterally opposite the tab on the other side wall.  As two plates positioned with the rear edges or surfaces of their flanges in a common plane are moved linearly toward engagement of the outer surfaces of opposing side walls, the tab extending from each opposing side wall is received in the opening in the other side wall.  An angled surface terminating at the shoulder of each tab contacts one edge of the opening in the other plate as movement progresses.  When the shoulders move past the edges of the opening, the tabs return to their unflexed positions, thus providing a snap fit coupling of the laterally adjacent plates.
