Thirty adults with traumatic brain injury (TBI) (20 males and 10 females, mean age 40 years) and a non-injured control group (12 males and 13 females, mean age 41 years) were tested on 16 tests of attention including three tasks of the Gordon Diagnostic System (GDS), a relatively new set of attention tasks. No differences between groups were found on age or(More)
Insig functions as a central regulator of cellular cholesterol homeostasis by controlling activity of HMG-CoA reductase (HMGR) in cholesterol synthesis. Insig both accelerates the degradation of HMGR and suppresses HMGR transcription through the SREBP-Scap pathway. The fission yeast Schizosaccharomyces pombe encodes homologs of Insig, HMGR, SREBP, and Scap,(More)
A method for non-invasive visualization of genetically labeled cells in animal disease models with micrometer-level resolution would greatly facilitate development of cell-based therapies. Imaging of fluorescent proteins (FPs) using red excitation light in the 'optical window' above 600 nm is one potential method for visualizing implanted cells. However,(More)
Chemokines are small proteins that function as immune modulators through activation of chemokine G protein-coupled receptors (GPCRs). Several viruses also encode chemokines and chemokine receptors to subvert the host immune response. How protein ligands activate GPCRs remains unknown. We report the crystal structure at 2.9 angstrom resolution of the human(More)
The relationship between self-reported history of traumatic brain injury (TBI) and psychiatric treatment outcome was investigated. TBI was hypothesized to be frequent, associated with cognitive deficits on neuropsychological testing, and less amenable to standard psychiatric treatment. Subjects were 42 psychiatric patients with a self-reported history of(More)
This study investigated the prevalence of traumatic brain injury (TBI) in an inpatient psychiatric population. We hypothesized increased prevalence of TBI relative to the general population due to a variety of risk factors observed in psychiatric patients. One hundred (mean age = 34) psychiatric inpatients completed the revised Head Injury Questionnaire.(More)
Performance data were collected on the Kaufman Brief Intelligence Test (K-BIT) from a total of 196 individuals from six diverse populations. College students did best, followed closely by closed head-injured adults and their controls; the order of performance then was learning-disabled children, psychiatric patients, and finally, neurosurgical patients in(More)
