Patent number: 9943592Abstract: Pharmaceutical or veterinary compositions, vaccine systems, methods, and kits for treating or protecting a subject from a condition using peptide-based adjuvants are provided. The peptide adjuvants comprise a peptide having a hydrophobic region, a turning region, and a hydrophilic region. The turning region comprises amino acid residues GSII (SEQ ID NO: 10). The peptide adjuvants can be used to immunopotentiate active agents by improving the immune response to the active agent.Type: GrantFiled: May 25, 2012Date of Patent: April 17, 2018Assignee: KANSAS STATE UNIVERSITY RESEARCH FOUNDATIONInventors: Xiuzhi Susan Sun, Jishu Shi

Patent number: 9441112Abstract: Compositions useful for preparing pressure sensitive adhesives, coatings, and/or films are provided, along with methods of making and using the same. The compositions are made from renewable, plant-based materials. The compositions comprise plant oil triglycerides that are polymerized and crosslinked to yield polymer matrices. Plant-based carriers and/or tackifiers can be used in the invention, including epoxidized plant oil triglycerides, acrylated epoxidized plant oil triglycerides, and dihydroxylated plant oil triglycerides. Natural tackifiers such as rosin esters and terpenes can also be used in the compositions. Dihydroxylated plant oil triglyceride tackifiers for use in biobased and synthetic adhesives are also provided.Type: GrantFiled: January 20, 2012Date of Patent: September 13, 2016Assignee: KANSAS STATE UNIVERSITY RESEARCH FOUNDATIONInventors: Xiuzhi Susan Sun, Byungjun Kollbe Ahn, Donghai Wang

Patent number: 8993017Abstract: The present invention relates to animal food products and methods of producing thereof. The methods of the present invention comprise mixing a binding agent with feed meal at a temperature of between about 10° C. and about 70° C. to produce a mash, passing the mash through an extruder to form an animal feed product, and drying the animal feed product. In certain embodiments, the temperature of the meal, mash and final product is kept at 70° C. or below.Type: GrantFiled: December 18, 2009Date of Patent: March 31, 2015Assignees: Hill's Pet Nutrition, Inc., Kansas State University Research FoundationInventors: Xiuzhi Susan Sun, Jihong Li, Pavinee Chinachoti, Luis J.

Publication number: 20140357837Abstract: The present invention broadly provides novel peptides that can be used to form hydrogels. The peptides are short (preferably 30 amino acid residues or less) and include hydrophilic and hydrophobic segments joined by a turning segment. The hydrogels are formed by altering the pH of a solution of these peptides to an acidic level, or by introducing a source of ions into a solution of these peptides. The resulting hydrogels are shear thinning gels that have high storage moduli and high rates of recovery after destruction. They find use in medical applications, including tissue engineering.Type: ApplicationFiled: August 18, 2014Publication date: December 4, 2014Inventors: Xiuzhi Susan Sun, Hongzhou Huang

Patent number: 8877951Abstract: Superparmagnetic acid-functionalized nanoparticle catalysts are provided along with methods of using the same to protonate an oxygen atom of a carbon-oxygen bond. Particularly, the catalysts comprise a nanoparticle having a ferromagnetic core surrounded by a metal oxide shell. The nanoparticle is at least partially coated with an acid-functionalized siloxane compound. The acid-functionalized nanoparticles may be used to catalyze any number of reactions that can be catalyzed in the presence of protons. The ferromagnetic core permits the nanoparticle catalyst material to be separated from the reaction medium through application of a magnetic field and reused.Type: GrantFiled: October 24, 2012Date of Patent: November 4, 2014Assignee: Kansas State University Research FoundationInventors: Hongwang Wang, Stefan Bossmann, Byungjun Kollbe Ahn, Xiuzhi Susan Sun
