  • Publication number: 20100198348
    Abstract: Described are biocompatible materials treated with a biocompatible substance that embeds within pores of the materials so as to alter the transmittance of radiation through the materials. Remodelable materials such as collagenous ECM materials can be so treated to provide implants that are both remodelable and possess an increased capacity to transmit visible light and/or other forms of radiation. Such constructs find particular use in ophthalmic applications and, in particular cases, as corneal implant materials.

  • Publication number: 20100120666
    Abstract: The present invention provides a glycopegylated G-CSF that is therapeutically active and which has pharmacokinetic parameters and properties that are improved relative to an identical, or closely analogous, G-CSF peptide that is not glycopegylated. Furthermore, the invention provides methods for mobilizing hematopoiesis in a subject, particularly a subject who has received or will receive radiation or chemotherapy treatment. The methods and compositions of the invention can further be used to prevent, alleviate and treat the myelosuppressive effects such therapies.

  • Publication number: 20100113743
    Abstract: The present invention provides conjugates between Factor VII or Factor VIIa peptides and PEG moieties. The conjugates are linked via an intact glycosyl linking group that is interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from both glycosylated and unglycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar moiety onto either an amino acid or glycosyl residue on the peptide. Also provided are pharmaceutical formulations including the conjugates. Methods for preparing the conjugates are also within the scope of the invention.

  • Publication number: 20090169509
    Abstract: The present invention provides polypeptides that include an O-linked glycosylation site that is not present in the wild-type peptide. The polypeptides of the invention include glycoconjugates in which a species such as a water-soluble polymer, a therapeutic agent of a biomolecule is covalently linked through an intact O-linked glycosyl residue to the polypeptide. Also provided are methods of making the peptides of the invention and methods, pharmaceutical compositions containing the peptides and methods of treating, ameliorating or preventing diseased in mammals by administering an amount of a peptide of the invention sufficient to achieve the desired response.
