Title: Fluorination of proteins and peptides for f-18 positron emission tomography
Inventor: GRIFFITHS GARY L
IPC: C07K1/107
Filed: 1998-09-03
Abstract: Thiol-containing peptides can be radiolabeled with fluorine-18 (F-18) by reacting a peptide comprising a free thiol group with an F-18-bound labeling reagent which also has a group that is reactive with thiols. The resulting F-18-labeled peptides may be targeted to a tissue of interest using bispecific antibodies or bispecific antibody fragments having on arm specific for the F-18-labeled peptide or a low molecular weight hapten conjugated to the F-18-labeled peptide, and another arm specific to the targeted tissue. The targeted tissue is subsequently visualized by clinincal positron emission tomography. The method for radiolabeling thiol-containing peptides with fluorine-18(F-18), comprises reacting a peptide comprising a free thiol group with a labelling reagent having the general formula 18F-(CH2)m-CR1,R2-(CH2)n-X, wherein: n is 0, 1 or 2; m is 0, 1 or 2; and n+m is 0, 1, or 2; X is selected from the group consisting of hydroxyl, cyano, iodide, bromide, chloride, azide, tosylate, mesylate, nosylate, triflate, unsubstituted maleimide, maleimide substituted with one or two alkyl groups, and 3-sulfo-maleimide; and R1 and R2 are the same or different and are selected from the group consisting of iodide, bromide, chloride, azide, tosylate, mesylate, nosylate, triflate, hydrogen, -CONH2, carboxyl, hydroxyl, sulfonic acid, tertiary amine, quaternary ammonium, unsubstituted maleimide, maleimide substituted with on or two alkyl groups, 3-sulfo-maleimide, unsubstituted alkyl, substituted alkyl, -COOR',-CONR'2, or COR', wherein the substituents of the substituted alkyl groups are selected from the group consisting of -CONH2, carboxyl, hydroxyl, sulfonic acid, tertiary amine and quaternary ammonium and wherein R' is a C1-C6 alkyl or phenyl.

Patent CA-2314769-A1 (CA)
Title: Combustion air intake apparatus for fuel-fired, direct vent heating appliance
Inventor: SCANLON JOHN H
IPC: F23L1/00
Filed: 2000-07-28
Abstract: An outside air intake hood for receiving combustion air for delivery to a direct vent, fuel-fired heating appliance such as a water heater has an opposing pair of side inlets positionable to face parallel to an outside wall upon which the hood is mounted, an outer side wall extending between the inlets, and an outlet passage with an entry portion facing and spaced inwardly apart from the outer side wall. A generally v-shaped baffle member is positioned within the hollow body of the hood, with an apex portion of the baffle member facing the entry portion of the outlet passage. When the wind is horizontally blowing generally parallel to the outside wall, a side wall of the baffle member deflects the wind-driven outside air entering one of the hood side inlets into the outlet passage in a manner converting momentum of the entering air into pressure in a manner preventing the creation of an undesirable vacuum at the hood outlet. A bypass passage disposed within the hood outwardly of the outlet passage entry portion communicates the two side outlets and prevents undesirable wind-created overpressurization of the outlet passage. Such bypass passage representatively extends through a gap between the baffle and the entry portion of the outlet passage and may also extend through the baffle itself.

IPC: G06Q40/06
Filed: 1999-04-21
Abstract: A computer system (10) including a processor (12) and a storage device storing a computer program product for rebalancing a capitalization weighted stock index are described. The computer program includes instructions for causing a computer to classify stocks in the index as Large Individual Stock if a stock has a capitalization weight above or equal to a first threshold or as a Small Individual Stock if the stock has a capitalization weight below the first threshold. The computer program causes the computer to scale down the Large Individual Stocks by an excess capitalization weight of the large stocks and distribute an aggregated excess capitalization weight of the Large Individual Stocks over the capitalization weights of the Small Individual Stocks. An iterative redistribution of excess capitalization over all Small Individual Stocks can be used to provided for less than proportional distribution of excess capitalization to very small capitalized stocks. The index rebalancing software (40) retains a capitalization weighting characteristic while permitting the index to conform to generally accepted accounting, economic and tax standards. Index rebalancing is accomplished while maintaining the original relative position of stocks and reducing the market impact of rebalancing on the Small Individual Stock group.
