Assessing Myogenic Response and Vasoactivity In Resistance Mesenteric Arteries Using Pressure Myography Ravirajsinh N. Jadeja1, Vikrant Rachakonda2, Zsolt Bagi3, Sandeep Khurana1 1Section of Gastroenterology and Hepatology, Georgia Regents University, 2Division of Gastroenterology and Hepatology, University of Pittsburgh School of Medicine, 3Vascular Biology Center, Georgia Regents University Pressure myography is used to assess vasoactivity of small arteries that develop sustained constriction when pressurized. This manuscript provides a detailed protocol to assess in isolated segments of small mesenteric arteries from rats, vasoactivity and the effect of intraluminal pressure on vascular diameter.
Coordinate Mapping of Hyolaryngeal Mechanics in Swallowing Thomas Z. Thompson1, Farres Obeidin1, Alisa A. Davidoff2, Cody L. Hightower1, Christohper Z. Johnson1, Sonya L. Rice1, Rebecca-Lyn Sokolove1, Brandon K. Taylor1, John M. Tuck1, William G. Pearson, Jr.3,4 1Medical College of Georgia, Georgia Regents University, 2Department of Communicative Sciences and Disorders, New York University, 3Department of Cellular Biology & Anatomy, Georgia Regents University, 4Department of Otolaryngology, Georgia Regents University Coordinate mapping is a method of documenting salient features of hyolaryngeal biomechanics in the pharyngeal phase of swallowing. This methodology uses image analysis software to record coordinates of anatomical landmarks. These coordinates are imported into an excel macro and translated into kinematic variables of interest useful in dysphagia research.
