Patent number: 9700040Abstract: The invention relates to polymeric systems for stabilizing, storing and delivering hypohalide salts. One system consists of material coated with two layers: one prepared from polyethylene glycol epoxide and melamine solution and second prepared from inorganic hypohalide salt solution. The material can be fabric, cotton, bamboo, cellulosic materials, blend of cellulosic and synthetic fibers. Antimicrobial materials comprising this system are also described. Another system consists of material containing pre-formed spaces coated with water-polyethylene glycol solution of hypohalide salt and encapsulated by film forming polymer. Hypohalide salts within both systems are in some cases storage stable for at least three months.Type: GrantFiled: January 20, 2011Date of Patent: July 11, 2017Assignee: The University of South DakotaInventors: Yuyu Sun, Zhengbing Cao, Simon Johnston

Patent number: 8992223Abstract: Polymers and copolymers including a functional polymer component may be used as conventional denture materials. Antifungal materials may be releasably bound to the functional polymer component such that the antifungal materials may be slowly eluted over an extended period of time to combat a fungal infection.Type: GrantFiled: February 18, 2011Date of Patent: March 31, 2015Assignee: The University of South DakotaInventors: Yuyu Sun, Zhengbing Cao, Xinbo Sun

Publication number: 20130299423Abstract: A new strategy to design container molecules is presented. Sulfonylcalix[4]arenes, which are synthetic macrocyclic containers, are used as building blocks that are combined with various metal ions and tricarboxylate ligands to construct metal-organic ‘super-containers’ (MOSCs). These MOSCs possess both endo and exo cavities and thus mimic the structure of viruses. The synthesis of MOSCs is highly modular, robust, and predictable.Type: ApplicationFiled: April 15, 2013Publication date: November 14, 2013Applicant: University of South DakotaInventor: University of South Dakota

Patent number: 7388125Abstract: The invention discloses a novel heat shock protein with high homology to chloroplast elongation factor EF-Tu. Also disclosed is a transgenic method for enhancing tolerance to heat and drought in female reproductive organs. It involves the temporal and spatial expression of novel heat shock EF-Tu in a plant organ or plant tissue. The invention also includes expression constructs, and methods for the production of crop plants with heritable phenotypes which are useful in breeding programs designed to increase heat and drought tolerance.Type: GrantFiled: December 7, 2004Date of Patent: June 17, 2008Assignees: Pioneer Hi-Bred International, Inc., The University of South DakotaInventors: Zoran Ristic, Shailendra K.
