Patent CA-2340324-A1 (CA)
Inventor: ROMANO CHARLES P
IPC: C07K14/415
Filed: 1999-08-19
Abstract: The present invention discloses methods and compositions comprising a group of novel expression cassettes which provide significantly improved levels of accumulation of Coleopteran inhibitory Cry3B and Cry3B variant amino acid sequences when these are expressed in plants. The preferred embodiments of the invention provide at least up to ten fold higher levels of insect controlling protein relative to the highest levels obtained using prior compositions. In particular, transgenic maize expressing higher levels of a protein designed to exhibit increased toxicity toward Coleopteran pests deliver superior levels of insect protection and are less likely to sponsor development of populations of target insects that are resistant to the insecticidally active protein.

Patent CA-2342967-A1 (CA)
Title: Modifying protein immunogenicity
Inventor: CARTER GRAHAM
IPC: C07K14/315
Filed: 1999-12-08
Abstract: It is known that proteins, or parts of them, may be rendered non- or less immunogenic to humans or other species by identifying one or more potential T cell epitopes and eliminating them by amino acid modification. Conventionall y, certain epitopes may be retained in a protein sequence if the peptides constituting such epitopes are present in endogenous human protein, since th ey would be recognised as "self". However, it has now been found that even self  epitopes may give rise to immune reactions. The invention provides for their  elimination, for example by recombinant DNA technology, to render them more useful for administration to humans, for example for therapeutic or diagnost ic purposes.

Patent CA-2372019-A1 (CA)
Inventor: MCARTHY TROY DANIEL
IPC: F01L3/08
Filed: 2002-02-14
Abstract: A valve stem seal assembly incorporates a cylindrical valve stem seal retainer having an axis and an upper end about which symmetrically and circumferentially arranged, alternating upper and lower fingers have depending ends which lie in two distinct planes in one preferred embodiment. The lower fingers depend radially inwardly toward the axis from the cylindrical body of the retainer to provide for axial securement of an elastomeric seal body to the top of a valve guide. The upper fingers extend axially upward from the same end, in the form of a gooseneck, and are adapted to apply a circumferential, radially inwardly directed spring force to the elastomeric seal body. The upper fingers are thus effective to eliminate the garter retainer springs used with conventional seal bodies of traditional valve stem seal assemblies.
