Diffuse axonal injury (DAI) secondary to traumatic brain injury (TBI) contributes to long-term functional morbidity. The corpus callosum (CC) is particularly vulnerable to this type of injury. Magnetic resonance spectroscopy (MRS) was used to characterize the metabolic status of two CC regions of interest (ROIs) (anterior and posterior), and their(More)
Neurofilaments (NF) and tubulin are highly phosphorylated proteins that are important in neuronal structure and function. Changes in phosphorylation alter their antigenicity, and previous studies examining the effect of ischemia on these proteins failed to consider this factor. Using phosphate-independent antibodies and a quantitative immunoassay, we(More)
Traumatic brain injury (TBI) is the leading cause of death and disability in children and can lead to a wide range of impairments. Brain imaging methods such as DTI (diffusion tensor imaging) are uniquely sensitive to the white matter (WM) damage that is common in TBI. However, higher-level analyses using tractography are complicated by the damage and(More)
We have cloned and sequenced a full length rabbit GLUT 1 and partial rabbit GLUT 3 cDNAs. The derived rabbit GLUT 3 peptide revealed 84% homology to the mouse, 82% to the rat, human, dog, and sheep, and 69% to the chicken GLUT 3 peptides. Using Northern blot analysis, we investigated the tissue and brain cellular distribution of GLUT 1 and GLUT 3(More)
UNLABELLED Traumatic brain injury (TBI) often results in traumatic axonal injury and white matter (WM) damage, particularly to the corpus callosum (CC). Damage to the CC can lead to impaired performance on neurocognitive tasks, but there is a high degree of heterogeneity in impairment following TBI. Here we examined the relation between CC microstructure(More)
BACKGROUND AND PURPOSE Victims of air embolism often recover rapidly on hyperbaric treatment then deteriorate again, even if hyperbaric treatment is continued. In previous animal experiments, lidocaine has been shown to improve recovery of somatosensory evoked response amplitude after air embolism. However, animals in these experiments rarely deteriorated.(More)
Traumatic brain injury (TBI) is the leading cause of death and disability in children. Diffusion weighted imaging (DWI) methods have been shown to be especially sensitive to white matter abnormalities in TBI. We used our newly developed autoMATE algorithm (automated multi-atlas tract extraction) to map altered WM integrity in TBI. Even so, tractography(More)
Objective. To prospectively determine the rate of unplanned extubations and contributing factors and determine whether a targeted intervention program would be successful in decreasing the rate of unplanned extubations. Design. Prospective, observational study. Setting. A 10-bed Pediatric Intensive Care Unit (PICU). Patients. All intubated pediatric(More)
Xanthine oxidase (XO), an enzyme that converts hypoxanthine to xanthine and xanthine to uric acid, is thought to contribute to hypoxic-ischemic brain injury by generating oxygen-free radicals during reperfusion. This is based largely on the observation that inhibition of XO reduces brain damage, but the precise mechanism by which the enzyme contributes to(More)
Traumatic brain injury (TBI) frequently results in diffuse axonal injury and other white matter damage. The corpus callosum (CC) is particularly vulnerable to injury following TBI. Damage to this white matter tract has been associated with impaired neurocognitive functioning in children with TBI. Event-related potentials can identify stimulus-locked neural(More)
