| 20110046346 | BIOMATERIAL WITH FUNCTIONALISED SURFACES - There is provided a biomaterial having a functionalised surface which comprises bi-functional semi-dendrimers. The biomaterial may be ceramic, metallic and/or polymeric. It will usually be in the form of a solid, but could be a semi-solid or hydrogel. There is also provided a method of making a biomaterial having a functionalised surface which comprises bi-functional semi-dendrimers, said method comprising adsorbing, grafting or synthesising in situ bi-functional semi-dendrimers onto the surface of a biomaterial. There is further provided a biomedical device which is coated with or formed from a biomaterial having a functionalised surface which comprises bi-functional semi-dendrimers. The biomedical device may be a medical implant, for example, such as a stent, artificial hip joint or replacement heart valve. FIG. | 02-24-2011 |
| 20110027880 | CELL CULTURE SYSTEM FOR PANCREATIC ISLANDS - Three-dimensional (3D) insulin-producing cell clusters derived from stem cells (preferably human embryonic stem cells) are provided by this invention, together with a method for their production using a microgravity bioreactor cell culture system. | 02-03-2011 |
| 20110027364 | BIOACTIVE AND RESORBABLE SOYBEAN-BASED BIOMATERIALS - A method of producing a soybean-based biomaterial which is suitable for use in a biomedical product, the method comprising: defatting soy flour; either prior to or at the same time as, performing a solvent extraction; to produce a biomaterial comprising variable levels of soy proteins, carbohydrates and isoflavones. The resulting biomaterials have a range of biomedical uses and are particularly desirable because of their isoflavone content. Examples of biomedical products containing the biomaterials include wound dressings; scaffolds for tissue engineering; fillers or implants for use in surgery; temporary barriers for use in dental or surgical procedures or to prevent post-surgical tissue adherence; carriers for the delivery of drugs, bioactive peptides or plasmids; anti-inflammatory agents; coatings for wound dressings or for dental, medical, surgical or veterinary devices or implants; and compositions for soothing skin or gum irritation. | 02-03-2011 |
| 20100279329 | METHOD FOR THE STABILISATION OF PURIFIED P-GLYCOPROTEIN - There is provided a method for producing purified P-glycoprotein (P-gp) in a stabilised form such that, after being reconstituted into proteoliposomes, it can be freeze dried and stored for prolonged periods of time without loss of biological activity The method comprises the steps of: i) solubilising a mixture of P-gp and other proteins obtained from cell membranes; ii) removing insoluble material by centrifugation; iii) placing the mixture of P-gp and other proteins in a purification column; and iv) running through the purification column at least one wash buffer so as to remove unwanted proteins, and then at least one elution buffer so as to recover the P-gp; wherein one or more of the buffers contains a disaccharide. Trehalose is a particularly preferred disaccharide. | 11-04-2010 |
| 20100069608 | BIOMATERIAL WITH FUNCTIONALISED SURFACES - There is provided a biomaterial having a functionalised surface which comprises bi-functional semi-dendrimers. The biomaterial may be ceramic, metallic and/or polymeric. It will usually be in the form of a solid, but could be a semi-solid or hydrogel. There is also provided a method of making a biomaterial having a functionalised surface which comprises bi-functional semi-dendrimers, said method comprising adsorbing, grafting or synthesising in situ bi-functional semi-dendrimers onto the surface of a biomaterial. There is further provided a biomedical device which is coated with or formed from a biomaterial having a functionalised surface which comprises bi-functional semi-dendrimers. The biomedical device may be a medical implant, for example, such as a stent, artificial hip joint or replacement heart valve. FIG. | 03-18-2010 |
