Patent CA-2288376-A1 (CA)
Title: Syndecan interacting proteins and the use thereof
Inventor: GROOTJANS JAN
IPC: C12Q1/68
Filed: 1998-04-22
Abstract: The invention relates to the identification of a protein that binds to the cytoplasmic domain of the syndecan. This protein, now called syntenin, contains a tandem repeat of PDZ-domains that reacts with the FYA C-terminal amino acid sequence of the syndecans (Trends Biochem.Sci., 20, p. 350, 1995:  Origin of PDZ {DHR, GLGF}, by M.B. Kennedy). Endogenous syntenin appears to be localized to the cytoskeleton. GFP-syntenin fusion-proteins decorate the plasma membrane and intracellular vesicles, where they co-localize and -segregate with syndecan cytoplasmic domains. Syntenin, therefore, is an unexpected candidate for connecting the cytoskeleton to heparan sulfate-assisted signal transduction pathways. The syndecan cytoplasmatic link (sycl) protein or syndecan interacting protein is referred to by the name "syntenin", meaning "putting tension on the syndecans".
Patent CA-2289474-A1 (CA)
Title: A method for incorporating psychological effects into demand models
Inventor: OUIMET KENNETH J
IPC: G06Q30/00
Filed: 1998-05-21
Abstract: A method for incorporating psychological effects into a demand model for pricing. First the original demand model is modified to include a mechanism to convert actual prices into perceived prices, thus causing the demand model to predict higher demand for certain prices. The user specifies the function that converts from real prices to perceived prices. This modified demand function is then fitted to a sales history to yield the parameters appropriate to its particular form. Also, the demand model can be modified to account for promotional effects. The user defines a visibility model, which gives the relative increase in demand for an item caused by a promotion, and the cost of the promotion. The demand model is modified to include the effect of increased demand based on the visibility, and a profit model is modified to account for the added cost due to the added visibility. The profit model is then optimized with respect to both prices and promotions.
