Title: Growth hormone variants and method for forming growth hormone variants
Inventor: WELLS JAMES A
IPC: C12Q1/68
Filed: 1989-10-30
Abstract: The invention provides methods for the systematic analysis of the structure and function of polypeptides by identifying active domains which influence the activity of the polypeptide with a target substance. Such active domains are determined by substituting selected amino acid segments of the polypeptide with an analogous polypeptide segment from an analog to the polypeptide. The analog has a different activity with the target substance as compared to the parent polypeptide. The activities of the segment-substituted polypeptide are compared to the same activity for the parent polypeptide for the target. A comparison of such activities provides an indication of the location of the active domain in the parent polypeptide. The invention also provides methods for identifying the active amino acid residues within the active domain of the parent polypeptide. The method comprises substituting a scanning amino acid for one of the amino acid residues within the active domain of the parent polypeptide and assaying the residue-substituted polypeptide so formed with a target substance. The invention further provides polypeptide variants comprising segment-substituted and residue-substituted growth hormones, prolactens and placental lactogens.

Title: Prostaglandin endoperoxide h synthase biosynthesis inhibitors
Inventor: LIU HUAQING
IPC: C07D237/14
Filed: 1999-10-27
Abstract: The present invention describes pyridazinone compounds of formula (I) which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important "housekeeping" enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectively of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).

Patent CA-2361244-A1 (CA)
Inventor: LAYNE RICHARD
IPC: A61F2/06
Filed: 2000-02-02
Abstract: Partially encapsulated stents are made using strips and bands of covering material. In one embodiment ringed stents are placed over an inner ePTFE tub e (e.g., supported on a mandrel) and are covered by a series of longitudinal strips. A series of spaced apart ePTFE circumferential bands can then be placed over the top of the longitudinal strips and ringed stents; alternatively bands alone or strips alone may be employed. All of the components of the structure are then laminated to the inner ePTFE tube to capture the stents. By selecting the size and position of the ePTFE bands, i t is possible to leave critical parts of the stent unencapsulated to facilitat e flexibility and expansion. The longitudinal strips can be woven about the stent of later laminated into position to provide an anti-compression functi on as well as overall structural stability. Although a single stent can be used , these approaches lend themselves to use of a plurality of individual ring stents spaced apart along the inner ePTFE tube.
