Abstract:
An improved biodegradable and biocompatible reconstituted monofilament collagen fiber having increased strength and elasticity is disclosed. The method of manufacture of the fiber, comprising a water bath step following a dehydration step, is also disclosed. Several embodiments of the collagen fiber are disclosed, including grafts, prosthetic devices, bundles of the fibers where the fibers of the bundle are tensioned and fail substantially in unison, and methods thereof. The fibers of the invention, or the embodiments of the fibers, may be coated or embedded in a polymer to protect the fibers and to bind them together. Additionally, proteoglycans may be incorporated into the fibers to enhance the ultimate tensile strength of the fibers.
Abstract:
In one embodiment, the present invention pertains to a protein having binding affinity to human chorionic gonadotrophin (hCG), luteinizing hormone (LH), and follicle stimulating hormone (FSH), comprising an amino acid sequence of 341 amino acids, wherein the protein is a chimera having an amino acid sequence homologous to the amino acid sequence of residues 1-92 of FSHR, an amino acid sequence homologous to the amino acid sequence of residues 93-170 of LHR, and an amino acid sequence homologous to the amino acid sequence of residues 171-341 of FSHR, wherein the protein is a chain of amino acids that is not naturally occurring as a binding protein. (LH numbering system). In another embodiment, the present invention pertains to a glycoprotein hormone receptor having binding affinity to human chorionic gonadotrophin (hCG), luteinizing hormone (LH), and follicle stimulating hormone (FSH), wherein the receptor comprises a transmembrane region and an extracellular N-terminus region, wherein the N-terminus region is a chimera containing an amino acid sequence of 341 amino acids comprising an amino acid sequence homologous to the amino acid sequence of residues 1-92 of FSHR, an amino acid sequence homologous to the amino acid sequence of residues 93-170 of LHR, and an amino acid sequence homologous to the amino acid sequence of residues 171-341 of FSHR, wherein the receptor is a chain of amino acids that is not naturally occurring as a receptor. (LH nmbering system).
Abstract:
Processes for preparaing biodegradable collagen-based matrices in sponge or sheet form wherein in one embodiment a collagen-based material including a collagen selected from the group consisting of types I, II and III collagens is freeze dried to form a collagen-based sponge which is contacted with a crosslinking agent selected from the group consisting of a carbodiimide or a succinimidyl active ester to form an intermediate collagen-based matrix which is subsequently subjected to conditions of severe dehydration to form the collagen-based matrix in sponge or sheet form. In another embodiment, a collagen-based sponge or sheet is first subjected to conditions of severe dehydration followed by contacting the thus formed intermediate collagen-based matrix with a carbodiimide crosslinking compound to form the collagen-based matrix in sponge or sheet form. In still another embodiment of the present invention the cross-linking agent is admixed with the collagen-based material prior to formation of the collagen-based sponge or sheet followed by processing steps of severe dehydration. In a paticularly preferred form of the invention, a carrier compound is incorporated during processing to form a collagen-based matrix in sponge or sheet form impregnated with a carrier compound wherein the carrier compound is selected from the group consisting of types IV and V collagen, fibronecting, laminin, hyaluronate, proteoglycan, epidermal growth factor, platelet derived growth factor, angiogenesis factor, antibiotic, antifungal agent, spermacidal agent, enzyme and enzyme inhibitor.

Abstract:
Methods of treating patients with dyskinesias, by administering a therapeutically effective amount of a dual-action mu-opioid receptor antagonist/kappa-opioid receptor agonist or prodrug thereof to a subject in need thereof, sufficient to mitigate the dyskinesia. Alternatively, a combination of both a mu-opioid receptor antagonist or prodrug thereof, and a kappa-opioid receptor agonist or prodrug thereof can be administered, either together or separately.
Abstract:
The present invention discloses vanadium-based insulin-mimetic agent composite coatings, application of these coatings onto implantable devices, and use of the implantable devices for accelerating osseous healing. The invention also encompasses methods of manufacturing implantable devices coated with vanadium-based insulin- mimetic agent composite coatings and the implantable devices so manufactured. The implantable devices have wide applications, including but not limited to treating bone fracture, bone trauma, arthrodesis, and other bone deficit conditions, as well as bone injuries incurred in military and sports activities.
