Publication number: 20090233888Abstract: The present invention relates to the treatment of a wide array of diseases and physiologic conditions based on modulating the level of hydrogen sulfide (H2S) in the body by at least partially eradicating small intestinal bacterial overgrowth (SIBO) in the gut. An H2S or lactulose breath test and/or detection of H2S or thiosulfate in the blood or urine may be used as a diagnostic and/or prognostic for assessing a systemic H2S load that exceeds a mammal's natural detoxification capacity. These tests may similarly be used to monitor the effectiveness of a therapeutic intervention for SIBO and/or the diseases or physiologic conditions whose pathology is linked thereto. Because SIBO is related to hyperhomocysteinemia, diseases and physiologic conditions that relate to hyperhomocysteinemia may further be monitored and treated in connection with the methods of the present invention.Type: ApplicationFiled: March 23, 2006Publication date: September 17, 2009Applicant: USC STEVENS, UNIVERSITY OF SOUTHERN CALIFORNIAInventor: Henry C.

Patent number: 7553627Abstract: There is disclosed an improved high-throughput and quantitative process for determining methylation patterns in genomic DNA samples based on amplifying modified nucleic acid, and detecting methylated nucleic acid based on amplification-dependent displacement of specifically annealed hybridization probes. Specifically, the inventive process provides for treating genomic DNA samples with sodium bisulfite to create methylation-dependent sequence differences, followed by detection with fluorescence-based quantitative PCR techniques. The process is particularly well suited for the rapid analysis of a large number of nucleic acid samples, such as those from collections of tumor tissues.Type: GrantFiled: September 8, 2006Date of Patent: June 30, 2009Assignee: University of Southern California, USC Stevens Center for InnovationInventors: Peter W.

Patent number: 6783082Abstract: A system utilizing a rotary atomizer for applying a liquid based substance to particles. In one example, a motor provides an in-line, direct drive force on a cage atomizer. With some systems, the cage atomizer has a vertical axis of rotation. With some systems, the motor is mounted external to the particle path and supported by a housing structure that provides an angled particle path. With some systems, other types of rotary atomizers may be used such as disk, bowl, or hollow disk rotary atomizers. With some examples of cage atomizers, a first portion of the cage atomizer may include a thread set that screws to a thread set of a second portion to hold a perforated structure in place. With some systems, the thread sets surround the axis of rotation.Type: GrantFiled: November 12, 2002Date of Patent: August 31, 2004Assignee: USC, L.L.C.Inventors: James H. Renyer, Gregory A. Renyer
