Bridging the Technology Divide in the COVID-19 Era: Using Virtual Outreach to Expose Middle and High School Students to Imaging Technology Kevin D. Phelan1, Mohsin Syed1, Noor Akhter1, Tiffany W. Huitt1, Gregory R. Snead2, Billy R. Thomas3, Karen L. Yanowitz4 1Division of Clinical Anatomy, Department of Neurobiology and Developmental Sciences, College of Medicine, University of Arkansas for Medical Sciences, 2Department of Emergency Medicine, College of Medicine, University of Arkansas for Medical Sciences, 3Department of Pediatrics, College of Medicine, University of Arkansas for Medical Sciences, 4Department of Psychology and Counseling, Arkansas State University This article presents an overview of how synchronous web-based virtual outreach can be used to expose 6th-12th grade students to advanced imaging technologies such as ultrasound, computerized tomography, and electroencephalography. The paper discusses the methods and equipment needed to livestream integrated educational sessions for effective student engagement in STEM.
Assessment of Dendritic Arborization in the Dentate Gyrus of the Hippocampal Region in Mice Devsmita Das1,2, Cristy Phillips3, Bill Lin1, Fatemeh Mojabi1, Mehmet Akif Baktir2, Van Dang1,2, Ravikumar Ponnusamy1, Ahmad Salehi1,2 1VA Palo Alto Health Care System, 2Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, 3Department of Physical Therapy, Arkansas State University We describe two methods for visualization and quantification of dendritic arborization in the hippocampus of mouse models: real-time and extended depth of field imaging. While the former method allows sophisticated topographical tracing and quantification of the extent of branching, the latter allows speedy visualization of the dendritic tree.
Profiling the Triacylglyceride Contents in Bat Integumentary Lipids by Preparative Thin Layer Chromatography and MALDI-TOF Mass Spectrometry Evan L. Pannkuk1, Thomas S. Risch2, Brett J. Savary3 1Graduate Program of Environmental Science, Arkansas State University, 2Department of Biological Sciences, Arkansas State University, 3Arkansas Biosciences Institute and College of Agriculture and Technology, Arkansas State University Mammalian integument contains solvent-extractable lipids that can provide chemical compositions characteristic of individual species. This paper presents a routine method for separating broad lipid classes isolated from integumentary tissues using thin layer chromatography and determining the triacylglyceride profile by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
