20080260799 | BIOACTIVE IMPLANT AND METHOD OF USE - The invention relates to a method for producing bioactive implant surfaces consisting of metallic or ceramic materials, to be used for implants such as artificial joints or very small implants such as so-called stents. The invention also relates to implants produced according to this method and methods of using the implants. | 10-23-2008 |
20080281069 | Polypeptide Connected With an Organic Residue - The invention relates to a method for producing a polypeptide which is modified with an organic group, wherein a bioactive polypeptide is covalently bound to an organic group that comprises a backbone structure having aromatic side chains, thereby forming a modified polypeptide which is constituted of the bioactive polypeptide and the group having aromatic side chains. At least one of the aromatic side chains of the group is subjected to chemical or enzymatic hydroxylation. | 11-13-2008 |
