Title: Compositions and methods for helper-free production of recombinant adeno-associated viruses
Inventor: GAO GUANG-PING
IPC: C12R1/92
Filed: 2000-02-24
Abstract: A method for producing recombinant adeno-associated virus in the absence of contaminating helper virus or wild-type virus involves culturing a mammalian host cell containing an rAd/AAV hybrid virus, an AAV rep sequence and an AAV cap sequence under the control of regulatory sequences directing expression thereof. The rAd/AAV hybrid virus contains an rAAV construct to be packaged into an AAV  virion in a backbone containing the adenoviral sequences necessary to express E1a and E1b gene products and to permit replication of the hybrid virus. The method of the invention permits replication of the hybrid virus and production of rAAV virion in this host cell in the absence of a helper virus and obviates a subsequent purification step to purify rAAV from contaminating virus.

Abstract: A portable water dispensing module is mounted to a refrigerator door inner liner. The liner has side walls with aligned vertically spaced module supports. The water dispensing module comprises a reservoir having a fill chamber located above a main reservoir. The fill chamber has a lid that has an opening closed by a cap. The reservoir supports the fill chamber and has side walls with anchoring supports that releasably and matingly engage with the module supports on the liner side walls to mount the water dispensing module against the liner walls. A lower recessed portion of the front wall of the reservoir protects a spigot, mounted into the recess, from inadvertent contact with a user. The reservoir further includes recessed handle portions on the side walls located forward of the refrigerator door liner side walls and below the fill chamber to facilitate the portability of the water dispensing module from the refrigerator door. The combined use of the fill chamber with the reservoir and the use of a filter in between permits for a relatively large volume of water to be stored in the water dispensing module on the inside of the refrigerator door without the use of any plumbing water lines having to pass through the refrigerator door. Further, when the door is closed, the water contained within the water dispensing module is chilled to provide a supply of filtered chilled water for a user.

Title: Golf bag having a longitudinal stay and a retainer clip therefor
Inventor: KELLER GARY E
IPC: A63B55/00
Filed: 2002-02-19
Abstract: A golf bag is provided with a throat structure disposed in an open top end of a generally tubular body with the throat structure having an opening formed therethrough that is divided into an open portion and an offset portion which is closed at its upper end. An elongated stay is located in a longitudinal position inside the tubular body, and the stay is inserted therein by moving it downwardly through the open portion of the throat structure opening. A retainer clip is removably mounted in the throat structure opening to retain an upper end of the stay in the offset portion of the opening. Removal of the stay may be accomplished by removing the retainer clip from the throat structure opening which allows movement of the stay upper end from the offset portion into the open portion so that the stay may be removed through the throat structure opening.

IPC: A61B6/03
Filed: 2000-06-22
Abstract: The present method is a process for reprojecting, or computing tomographic projections of an image (12), based on multilevel image domain decomposition. The method includes decomposing an image (12) into one or more sub-images (14, 16, 18, 20), followed by reprojection of the sub-images (14, 16, 18, 20) into sinograms (22, 24, 26, 28), appropriate scaling of the sinograms, and aggregation of the sub-image sinograms (22, 24, 26, 28) into a single sinogram (14) of the entire image (12). The multilevel process attains image quality comparable to that of direct reprojection methods, while requiring much less computation, and therefore being much faster.
