Patent number: 9855320Abstract: 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.Type: GrantFiled: February 27, 2012Date of Patent: January 2, 2018Assignee: CHUNG-ANG UNIVERSITY INDUSTRY-ACADEMIC COOPERATION FOUNDATIONInventors: Jae Chan Kim, Doo Hwan Oh, Kwang Sic Joo, Yeoun Sook Chun, Sung Wook Wee, Kyoung Woo Kim

Publication number: 20150101979Abstract: 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.Type: ApplicationFiled: April 10, 2013Publication date: April 16, 2015Inventors: Yong Lak Joo, Daehwan Cho, Kyoung Woo Kim
