Patent number: 8460269Abstract: The disclosed technology describes compositions and methods useful for providing cell based therapy. For example, one embodiment of cell based therapy involves the regeneration of injured tissue and/or promoting wound healing. Certain embodiments provide improved therapeutic compositions using microbubbles by delivering biological progenitor cells to the injured tissues. The administration of the microbubbles is directed by acoustic radiation forces that interact with embodiments of microbubbles comprising an acoustically active gas. As such, a high efficiency of progenitor cell delivery to injured tissue is realized. One advantage of this technique over targeted delivery of pharmaceutical compounds, is that the delivered progenitors cells may be derived from the patient (i.e., personalized therapy), thereby avoiding side effects, allergic reactions, and overall problems associated with refractive drug responses.Type: GrantFiled: September 13, 2010Date of Patent: June 11, 2013Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: Catalin Toma, Flordeliza Villanueva, William Richard Wagner, Joon S.

Patent number: 6932966Abstract: A skin treatment mixture for treating pierced skin such as that resulting from a body piercing procedure includes sea salt, lysozyme and reconstituted ocean water. The reconstituted ocean water preferably is the product of reverse osmosis of water. The skin treatment mixture preferably additionally includes sodium benzoate to act as a preservative. A method of producing a skin treatment mixture includes the steps of providing a quantity of purified water; adding a quantity of sea salt to the quantity of purified water; boiling the purified water and sea salt; cooling the purified water and sea salt; adding a quantity of lysozyme to the purified water and sea salt; sterilizing the mixture and testing it for bacteria. A method of treating a pierced skin area includes the step of applying to the pierced area a reconstituted ocean water mixture of sea salt and lysozyme.Type: GrantFiled: June 20, 2003Date of Patent: August 23, 2005Inventor: Edward Kolos

Patent number: 6927237Abstract: The present invention relates to two solvent antimicrobial compositions and methods employing these two solvent compositions. The two solvent compositions typically contain a second solvent that is not or is only sparingly soluble in a diluting solvent. The two solvent composition can form a clear single-phase solution. The two solvent antimicrobial compositions can reduce the population of microbes on various surfaces such as facilities, containers, or equipment found in food, beverage, or pharmaceutical industries at temperatures between about ?70° C. to about 100° C.Type: GrantFiled: February 28, 2002Date of Patent: August 9, 2005Assignee: Ecolab Inc.Inventors: Robert D.
