Biomarkers in an Animal Model for Revealing Neural, Hematologic, and Behavioral Correlates of PTSD Min Jia1, Fei Meng2, Stanley E. Smerin1, Guoqiang Xing1, Lei Zhang1, David M. Su2, David Benedek1, Robert Ursano1, Yan A. Su2, He Li1 1Department of Psychiatry, Center for the Study of Traumatic Stress, Uniformed Services University of the Health Sciences, Bethesda, Maryland, 2Department of Gene and Protein Biomarkers, GenProMarkers, Inc. We describe a rat model of post traumatic stress disorder (PTSD) that reveals the persistent alterations in neuroendocrine function and the delayed long-term, exaggerated fear response, characteristic of PTSD patients. The animal model and methods described here are useful for correlating biomarkers in brain nuclei, which are mechanistic but cannot be measured in patients, with biomarkers in peripheral white blood cells, which can.
In Situ Characterization of Boehmite Particles in Water Using Liquid SEM Juan Yao1, Bruce W. Arey1, Li Yang1, Fei Zhang1, Rachel Komorek1, Jaehun Chun1, Xiao-Ying Yu1 1Earth & Biological Sciences Directorate, Pacific Northwest National Laboratory We present a procedure for real-time imaging and elemental composition analysis of boehmite particles in deionized water by in situ liquid Scanning Electron Microscopy.
Laser Doppler: A Tool for Measuring Pancreatic Islet Microvascular Vasomotion In Vivo Mingming Liu1, Xiaoyan Zhang1, Bingwei Li1, Bing Wang1, Qingbin Wu1, Fei Shang1, Ailing Li1, Hongwei Li1, Ruijuan Xiu1 1Institute of Microcirculation, Chinese Academy of Medical Sciences & Peking Union Medical College Pancreatic islet microvascular vasomotion regulates islet blood distribution and maintains the physiological function of islet β cells. This protocol describes using a laser Doppler monitor to determine the functional status of pancreatic islet microvascular vasomotion in vivo and to assess the contributions of pancreatic islet microcirculation to pancreatic-related diseases.
