Radiotracer Administration for High Temporal Resolution Positron Emission Tomography of the Human Brain: Application to FDG-fPET Sharna D. Jamadar1,2,3, Phillip G.D. Ward1,2,3, Alexandra Carey1,4, Richard McIntyre1,4, Linden Parkes1,3, Disha Sasan1, John Fallon1, Edwina Orchard1,2,3, Shenpeng Li1,5, Zhaolin Chen1,5, Gary F Egan1,2,3 1Monash Biomedical Imaging, Monash University, 2Australian Research Council Centre of Excellence for Integrative Brain Function, 3Turner Institute for Brain and Mental Health, Monash University, 4Department of Medical Imaging, Monash Health, 5Department of Electrical and Computer Systems Engineering, Monash University This manuscript describes two radiotracer administration protocols for FDG-PET (constant infusion and bolus plus infusion) and compares them to bolus administration. Temporal resolutions of 16 s are achievable using these protocols.
Optical Clearing and Imaging of Immunolabeled Kidney Tissue Turgay Saritas1, Victor G. Puelles1,2,3, Xiao-Tong Su4, David H.

Described here is a simple method to combine immunolabeling of thick kidney slices, optical clearing with ethyl cinnamate, and confocal imaging that enables visualization and quantification of three-dimensional kidney structures.
Ovine Lumbar Intervertebral Disc Degeneration Model Utilizing a Lateral Retroperitoneal Drill Bit Injury Kai-Zheong Lim*1, Christopher D. Daly*1,2,3, Peter Ghosh4, Graham Jenkin3, David Oehme5, Justin Cooper-White6,7, Taryn Naidoo6, Tony Goldschlager1,8 1Department of Surgery, Monash University, 2Department of Neurosurgery, Monash University, 3The Ritchie Centre, Hudson Institute of Medical Research, 4Proteobioactives, Pty Ltd, 5 Intervertebral disc degeneration is a significant contributor to back pain and a leading cause of disability worldwide. Numerous animal models of intervertebral disc degeneration exist. We demonstrate an ovine model of intervertebral disc degeneration, utilizing a drill bit, which achieves a consistent disc injury and reproducible level of disc degeneration.
