Abstract: The invention provides for the production of several humanized murine antibodies specific for the antigen Lewis Y, which is recognized by the murine antibody Lewis Y. The Lewis Y antigen is expressed in normal tissues but the level of expression is higher in certain tumor types so that the antigen can be used as a marker for cells of some breast, colon, gastric, esophageal, pancreatic, duodenal, lung, bladder and renal carcinomas and gastric and islet cell neuroendocrine tumors. The invention also provides for numerous polynucleotide encoding humanized Lewis Y specific antibodies, expression vectors for producing humanized Lewis Y specific antibodies, and host cells for the recombinant production of the humanized antibodies. The invention also provides methods for detecting cancerous cells (in vitro and in vivo) using humanized Lewis Y specific antibodies. Additionally, the invention provides methods of treating cancer using humanized Lewis Y specific antibodies.

Abstract: The invention provides for the production of several humanized murine antibodies specific for the Lewis b antigen, which is recognized by the murine antibody 58-1066. The antigen is expressed on cell lines from colon, lung, bladder, breast, renal, pancreatic and ovarian cancers. The expression of the antigen is greatly increased in cancer tissues as compared to its expression in the corresponding normal tissue. The invention also provides for numerous polynucleotide encoding humanized Lewis b antigen specific antibodies, expression vectors for producing humanized Lewis b antigen specific antibodies, and host cells for the recombinant production of the humanized antibodies. The invention also provides methods for detecting cancerous cells (in vitro and in vivo) using humanized Lewis b antigen specific antibodies. Additionally, the invention provides methods of treating cancer using Lewis b antigen specific antibodies.

Abstract: In a six high rolling mill comprising each pair of upper and lower work rolls, intermediate rolls and backup rolls, at least the intermediate rolls of the work and intermediate rolls being adapted for shifting in axial directions thereof, each of the intermediate rolls has a barrel length longer than that of the backup roll such that barrel ends of the intermediate roll extend beyond barrel ends of the-backup roll at maximum and minimum shifted positions of the intermediate roll, thereby providing a six high rolling mill having a high mill rigidity.

Abstract: Graphite cast iron is diecast at a solid-liquid coexisting state with a mold having a gate opened at an area of not more than 1/10 of a pressurized area of a plunger tip.

Abstract: This invention effectively smoothens the steel sheet surface after final cold rolling by removing oxidation scale produced on the steel sheet surface in the production steps of grain oriented silicon steel sheets, particularly after intermediate annealing and at a stage before the final cold rolling, or further forming grooves onto the steel sheet surface along the rolling direction, and hence can utilize high speed tandem rolling for the final cold rolling, whereby the production of grain oriented silicon steel sheets having excellent magnetic properties is realized in a high productivity.
