  • Patent number: 9855320
    Abstract: The present invention provides a pharmaceutical composition for the prevention or treatment of glaucoma, wherein the pharmaceutical composition includes angiogenin or a fragment thereof as an active ingredient. Angiogenin or a fragment thereof according to the present invention activates aqueous humor outflow due to NO generation increase, Schlemm's canal expansion, and intercellular interval widening, thereby reducing intraocular pressure. Accordingly, angiogenin and a fragment may be useful for the prevention and treatment of glaucoma.

  • Patent number: 9050301
    Abstract: Provided is a pharmaceutical composition for treating corneal endothelium wounds, the composition including angiogenin as an effective ingredient. The present invention relates to a new topical therapeutic use of angiogenin for treatment of corneal endothelium wounds, wherein the angiogenin that is generally known to be involved in angiogenesis activates a PI3K/Akt/eNOS pathway thereof in ocular corneal endothelium to increase migration and proliferation of corneal endothelial cells that are not capable of self-proliferation and to promote prevention and treatment of corneal endothelial cell wounds.

  • Publication number: 20150101979
    Abstract: A surface treatment method is described herein where a stabilizing (e.g., crosslinking agent) is pre-mixed into a fluid stock comprising a processable polymer. The stock is processed to form products (e.g., nanofibers or films), followed by exposing the products to a stabilizing (e.g., crosslinking catalyst, such as acid vapors), which results in stabilization (e.g., polymer cross-linking on the surface of the product). In some embodiments, the morphology of the product is not changed upon crosslinking. Moreover in some instances, this method does not need strong acids and is performed with weak acids such as acetic acid which reduces environmental pollution. In addition to water soluble polymers (e.g., PVA), this method is applicable to proteins such as soy protein, and combinations of polymers and proteins in various embodiments.
