Title: Keyhole limpet hemocyanin composition with enhanced anti-tumor activity against bladder cancer
Inventor: EBERT RAY F
IPC: A61P35/00
Filed: 1994-04-14
Abstract: ABSTRACT      The present invention i  directed to a stabilized keyhole limpet hemocyanin (KLH) composition in which (i) its intact non-degraded subunit is approximately 400,000 in molecular weight based on SDS-PAGE analysis; and (ii) are contained at least about 50% didecameric or higher KLH multimers,  based  on  sedimentation-equilibrium  and/or sedimentation-velocity ultracentrifugation analyses. The KLH composition is stabilized at 4°C by dissolving and storing it in an isotonic buffer preferably containing calcium and magnesium.  It is critical that the KLH not have been frozen or lyophilized during its preparation or storage.  The  KLH  composition  demonstrates  enhanced immunogenic  activity,  particularly enhanced anti-tumor activity,  which  is  reduced  if  the KLH  is  frozen  or lyophilized.  The KLH composition of the present invention exhibits enhanced anti-tumor activity in a murine bladder tumor model and thereby represents a new and useful anti-tumor immunotherapeutic anti-bladder cancer.

Title: Liver reserve cells
Inventor: NAUGHTON BRIAN A
IPC: A61K35/407
Filed: 1993-10-08
Abstract: The present invention relates to liver reserve or stem cells. In particular, it relates to the isolation, characterization, cultur-ing, and uses of liver reserve cells. Liver reserve cells isolated by density gradient centrifugation can be distinguished from other liver parenchymal cells by their morphology, staining characteristics, high proliferative activity and ability to differentiate in vitro. In long-term cultures described herein, these cells expand in numbers and differentiate into morphologically mature liver parenchymal cells, capable of mediating liver-specific functions. Therefore, isolated liver reserve cells may have a wide range of applications, including, but not limited to, their uses as vehicles of exogenous genes in gene therapy, and/or to replace and reconstitute a destroyed, infected, or genetically deficient mammalian liver by transplantation.

Filed: 1994-03-16
Abstract: A system (10) for mixing cementatious material, liquid and aggregate to form concrete includes a cementatious  material measuring device (12) which provides dry cementatious material to an enclosed screw conveyor assembly (14). The dry cementatious material is thoroughly mixed with a liquid (68) within the screw conveyor (14) to form a flowable slurry without producing external cement dust pollution. The slurry is output by the screw conveyor (14) into a final product mixing chamber (16) where the flowable slurry is mixed together with aggregate to form concrete. The screw conveyor assembly (14) has an in-line input (20) and output (22), and space-saving diverging/converging conveyor sections (28, 56) to facilitate the retrofitting of existing concrete mixing plants. The conveyor assembly (14) includes a cement metering function as well as a slurry mixing function. A selectively openable and closable bypass gate (90) permits the dry cementatious material to be sent directly to the final product mixing chamber (16) in the event of conveyor failure.
