Scanning Light Scattering Profiler (SLPS) Based Methodology to Quantitatively Evaluate Forward and Backward Light Scattering from Intraocular Lenses Bennett N. Walker1, Robert H. James2, Don Calogero1, Ilko K. Ilev2 1Office of Device Evaluation, Center for Devices and Radiological Health, U.S. Food and Drug Administration, 2Optical Therapeutics and Medical Nanophotonics Laboratory, Office of Science and Engineering Laboratories, Center for Devices and Radiological Health, U.S. Food and Drug Administration This protocol describes the scanning light scattering profiler (SLSP) that enables the full-angle quantitative evaluation of forward and backward scattering of light from intraocular lenses (IOLs) using goniophotometer principles.
Detection of Foodborne Bacterial Pathogens from Individual Filth Flies Monica Pava-Ripoll1, Rachel E.G. Pearson1, Amy K. Miller1, George C. Ziobro1 1Center for Food Safety and Applied Nutrition, U.S. Food and Drug Administration A PCR-based protocol was adapted to detect Cronobacter spp., Salmonella enterica, and Listeria monocytogenes from body surfaces and alimentary canals of individual wild-caught flies. The goal of this protocol is to detect and isolate bacterial pathogens from individual insects collected as part of an environmental sampling program during foodborne outbreak investigations.
A Visual Description of the Dissection of the Cerebral Surface Vasculature and Associated Meninges and the Choroid Plexus from Rat Brain John F. Bowyer1, Monzy Thomas1, Tucker A. Patterson1, Nysia I. George2, Jeffrey A. Runnells3, Mark S. Levi1 1Division of Neurotoxicology, National Center for Toxicological Research, 2Division of Personalized Nutrition and Medicine, National Center for Toxicological Research, 3Office of Planning, Finance, and Information Technology, National Center for Toxicological Research This video presentation shows a method of harvesting the two most important highly vascular structures that support forebrain function. They are the cerebral surface (superficial) vasculature along with associated meninges (MAV) and the choroid plexus which are necessary for cerebral blood flow and cerebrospinal fluid (CSF) homeostasis.
