Magnetic resonance imaging (MRI) is increasingly used in the assessment of the severity and progression of neurotrauma. We evaluated temporal and regional changes after mild fluid percussion (FPI) and controlled cortical impact (CCI) injury using T2-weighted-imaging (T2WI) and diffusion-weighted imaging (DWI) MRI over 7 days. Region of interest analysis of(More)
Magnocellular neuroendocrine cells of the supraoptic nucleus (SON) release vasopressin (VP) systemically and locally during osmotic challenge. Although both central VP and nitric oxide (NO) release appear to reduce osmotically stimulated systemic VP release, it is unknown whether they interact locally in the SON to enhance somatodendritic release of VP, a(More)
Iron is a trace metal essential for normal brain development but toxic in excess as it is capable of generating highly reactive radicals that damage cells and tissue. Iron is stringently regulated by the iron regulatory proteins, IRP1 and IRP2, which regulate proteins involved in iron homeostasis at the posttranscriptional level. In this study, 12 distinct(More)
CONCLUSION Our findings show that all cochlear implanted temporal bones had a varied degree of trauma and inflammatory reaction from cochlear implantation. No definitive relationship was observed from our limited number of specimens between residual spiral ganglion cells (SGCs) in implanted temporal bones and clinical speech performance. OBJECTIVES We(More)
