Publication number: 20150010672Abstract: The embodiments described herein provide a method for improving bowel health by increasing short chain fatty acid concentration in the colon of a mammal including administering to the mammal a composition having from about 0.1 grams to about 50 grams of a treated bran product. After administration, the treated bran product results in an increased short chain fatty acid production during fermentation in the colon as compared to untreated bran fermented in the colon.Type: ApplicationFiled: September 19, 2014Publication date: January 8, 2015Applicant: Purdue Research FoundationInventors: Bruce R. Hamaker, Devin J. Rose, Ali Keshavarzian, Pinthip Rumpagaporn, Osvaldo H. Campanella, Bradley L. Reuhs

Publication number: 20140179629Abstract: Compositions which provide slowly digestible starch and a source of fermentable dietary fiber. Microparticles in which starch is entrapped in a crosslinked matrix to provide dietary benefit. Such microparticles are used to deliver glucose to targeted regions in the small intestine for beneficial physiological effects, and fermentable dietary fiber to the colon to improve colon health and to treat diseases of the colon. Microparticles can be employed to selectively deliver fermentable dietary fiber to targeted portions of the colon.Type: ApplicationFiled: October 14, 2013Publication date: June 26, 2014Applicants: RUSH UNIVERSITY MEDICAL CENTER, PURDUE RESEARCH FOUNDATIONInventors: BRUCE R. HAMAKER, MAHESH VENKATACHALAM, GENYI ZHANG, ALI KESHAVARZIAN, DEVIN J. ROSE

Publication number: 20140147856Abstract: A method of identifying a subject at risk of developing or having a neurodegenerative disorder is provided. The method includes obtaining a biological sample from the subject and assaying a level of a marker of intestinal permeability in the sample. The method further includes comparing the subject's level to a control level for the marker of intestinal integrity and identifying the subject having an increased intestinal permeability relative to the control intestinal permeability as having an increased risk of developing or having a neurodegenerative disorder. A method of monitoring the efficacy of a treatment for a neurodegenerative disorder is also provided.Type: ApplicationFiled: November 25, 2013Publication date: May 29, 2014Applicant: Rush University Medical CenterInventors: Christopher Forsyth, Maliha Shaikh, Kathleen Shannon, Jeffrey Kordower, Ali Keshavarzian, David A.

Microparticles in which starch is entrapped in a crosslinked matrix to provide dietary benefit. Such microparticles are used to deliver glucose to targeted regions in the small intestine for beneficial physiological effects, and fermentable dietary fiber to the colon to improve colon health and to treat diseases of the colon. Microparticles can be employed to selectively deliver fermentable dietary fiber to targeted portions of the colon. A method for making the microparticles is provided as well as methods for using the microparticles for controlled digestion of starch on ingestion in the small intestine and methods for using the microparticles to deliver dietary fiber. The microparticles with entrapped starch provide a low glycemic index and extended glucose release in food products and food ingredients.Type: GrantFiled: December 6, 2006Date of Patent: October 15, 2013Assignees: Purdue Research Foundation, Rush University Medical CenterInventors: Bruce R.

Publication number: 20040132111Abstract: The presence of oxidative stress in a patient is determined by immobilizing tissue proteins onto a support, derivatizing any oxidized or nitrated proteins with 2,4-dinitrophenylhydrazine (DNPH), contacting the derivatized tissue proteins with anti-DNPH antibody or anti-nitrotyrosine antibody, then measuring the amount of immunocomplex formed.Type: ApplicationFiled: July 24, 2003Publication date: July 8, 2004Inventors: Ali Banan, Ali Keshavarzian

Publication number: 20030068658Abstract: The presence of oxidative stress in a patient is determined by immobilizing plasma proteins onto a support, derivatizing any oxidized proteins with 2,4-dinitrophenylhydrazine (DNPH), contacting the derivatized plasma proteins with anti-DNPH antibody, then measuring the amount of immunocomplex formed. In a preferred embodiment, the plasma proteins are bound to a membrane, derivatized with DNPH, contacted with anti-DNPH antibody, with the amount of immunocomplex formed being determined by contacting the immunocomplex with a second antibody labeled with horseradish peroxidase in conjunction with chemiluminescence.Type: ApplicationFiled: October 2, 2002Publication date: April 10, 2003Applicant: Rush Presbyterian St. Luke's Medical CenterInventors: Ali Keshavarzian, Ali Banan
