| 20110006453 | HYDRODYNAMIC SPINNING OF POLYMER FIBER IN COAXIAL LAMINAR FLOWS - A polymer fiber is formed by hydrodynamic spinning. Fluids are forced to flow through a conduit to form a laminar flow comprising three or more layers of generally coaxial fluid flows, at respective flow rates selected to define a cross-section of a tubular middle layer of the fluid flows. The middle layer comprises a cross-linkable polymer precursor. Another layer of the fluid flows comprise a cross-linking agent. The polymer precursor, cross-linking agent and fluids are selected to prevent substantial diffusion of the polymer precursor away from the middle layer, and to allow a portion of the cross-linking agent to diffuse from the another layer into the middle layer to facilitate cross-linking of the polymer precursor in the middle layer to form a tubular polymer layer in a polymer fiber. The polymer layer thus has a cross-section generally corresponding to the cross-section of the middle layer. | 01-13-2011 |
| 20110044992 | METHOD OF DELIVERING AN ANTI-CANCER AGENT TO A CELL - There is provided a delivery vehicle comprising an anti-cancer agent together with a conjugate of a delivery agent containing a free aldehyde and a flavonoid, having the delivery agent conjugated at the C6 and/or the C8 position of the A ring of the flavonoid. The resulting delivery vehicles may be used to deliver an anti-cancer agent to a cell. | 02-24-2011 |
| 20110135733 | ALDEHYDE CONJUGATED FLAVONOID PREPARATIONS - There is provided a method of conjugating a polymer containing a free aldehyde group with a flavonoid in the presence of an acid catalyst, such that the polymer is conjugated to the C6 or C8 position of the flavonoid A ring. The resulting conjugates may be used to form delivery vehicles to deliver high doses of flavonoids, and may also be used as delivery vehicles to deliver an additional bioactive agent. | 06-09-2011 |
| 20120016015 | ALDEHYDE CONJUGATED FLAVONOID PREPARATIONS - There is provided a method of conjugating a polymer containing a free aldehyde group with a flavonoid in the presence of an acid catalyst, such that the polymer is conjugated to the C6 or C8 position of the flavonoid A ring. The resulting conjugates may be used to form delivery vehicles to deliver high doses of flavonoids, and may also be used as delivery vehicles to deliver an additional bioactive agent. | 01-19-2012 |
| 20120070433 | FLAVONOID HYDROGEL - There is provided methods for producing a hydrogel comprising conjugates of a hydrogel forming agent and a flavonoid including a method for producing a hydrogel that is capable of adhesion of cells and which comprises enzymatically cross-linked conjugates of a hydrogel forming agent and a flavonoid. There is also provided a method for producing a hydrogel comprising conjugates of a hydrogel forming agent and a flavonoid without the addition of an exogenous peroxide or peroxidase or without the addition of an exogenous peroxide. Hydrogels produced by such methods and methods of using the hydrogels are also described herein. | 03-22-2012 |
