Macknik2,3 1División de Neurociencias, Universidad Pablo de Olavide, 2Barrow Neurological Institute, 3Ophthalmology, Neurology, and Physiology/Pharmacology, SUNY Downstate Medical Center Whereas multiphoton imaging is only effective at limited depths from the tissue’s surface, it is possible to achieve 3 µm resolution imaging at any depth via pCLE. Here, we present a protocol to conduct pCLE imaging to measure microvascular dynamics in the hippocampus of ictal and wild-type mice. Neuroscience Simultaneous Cryosectioning of Multiple Rodent Brains Tabitha R.F. Green1,2,3, J. Bryce Ortiz1, Jordan L. Harrison5, Jonathan Lifshitz1,3,4, Rachel K. Rowe1,3,4 1Department of Child Health, University of Arizona College of Medicine, 2Department of Biological Sciences, University of Bath, 3BARROW Neurological Institute at Phoenix Children's Hospital, 4Phoenix Veteran Affairs Healthcare System, 5Department of Basic Medical Sciences, University of Arizona College of Medicine Here, we present a protocol to freeze and section brain tissue from multiple animals as a timesaving alternative to processing single brains. This reduces staining variability during immunohistochemistry and reduces time cryosectioning and imaging.

Bioengineering PLGA Nanoparticles Formed by Single- or Double-emulsion with Vitamin E-TPGS Rebecca L. McCall1, Rachael W. Sirianni1 1Barrow Brain Tumor Research Center, Barrow Neurological Institute We describe the production and characterization of nanoparticles and microparticles composed of poly(lactic-co-glycolic acid) using vitamin E-TPGS as an emulsifier. By varying formulation parameters such as the concentration of emulsifier, it is possible to produce nanoparticles with mean diameters ranging from 220 nm to 1.98 µm.

Scheck1,2 1Neuro-Oncology Research, Barrow Neurological Institute of St. Joseph’s Hospital and Medical Center, 2Neurosurgery Research Laboratory, Barrow Neurological Institute of St. Joseph’s Hospital and Medical Center Intracranial implantation of GL261 cells into C57BL/6 mice produces malignant gliomas that recapitulate many of the hallmarks of human glioblastoma multiforme. We used GL261 cells stably expressing luciferase to allow us to use in vivo imaging to follow tumor progression. The surgery and 3D in vivo imaging are demonstrated.
