Mild traumatic brain injury (mTBI) is considered the 'signature injury' of combat veterans that have served during the wars in Iraq and Afghanistan. This prevalence of mTBI is due in part to the common exposure to high explosive blasts in combat zones. In addition to the threats of blunt impact trauma caused by flying objects and the head itself being(More)
A key step in the regulation of gene expression is the sequence-specific binding of transcription factors (TFs) to their DNA recognition sites. However, elucidating TF binding site (TFBS) motifs in higher eukaryotes has been challenging, even when employing cross-species sequence conservation. We hypothesized that for human and mouse, many orthologous genes(More)
The chronic effects of repetitive head impacts (RHI) on the development of neuroinflammation and its relationship to chronic traumatic encephalopathy (CTE) are unknown. Here we set out to determine the relationship between RHI exposure, neuroinflammation, and the development of hyperphosphorylated tau (ptau) pathology and dementia risk in CTE. We studied a(More)
BACKGROUND The current gold standard for diagnostic classification of many solid-tissue neoplasms is immunohistochemistry (IHC) performed on formalin-fixed, paraffin-embedded (FFPE) tissue. Although IHC is commonly used, there remain important issues related to preanalytic variability, nonstandard methods, and operator bias that may contribute to clinically(More)
Ipilimumab (MDX-010), a human anti-cytotoxic T-lymphocyte antigen (CTLA)-4 monoclonal antibody, is currently being investigated for the treatment of patients with melanoma. The most frequent toxicities observed with ipilimumab involve the gastrointestinal tract and are attributed to activation of the immune system. Constipation has been reported as a(More)
Concussions following head and/or neck injury are common, and although most people with mild injuries recover uneventfully, a subset of individuals develop persistent post-concussive symptoms that often include headaches. Post-traumatic headaches vary in presentation and may progress to become chronic and in some cases debilitating. Little is known about(More)
Cognitive impairment, including dementia, is commonly seen in those afflicted with Parkinson disease (PD), particularly at advanced disease stages. Pathologically, PD with dementia (PD-D) is most often associated with the presence of cortical Lewy bodies, as is the closely related dementia with Lewy bodies (DLB). Both PD-D and DLB are also frequently(More)
Blast exposure can cause mild traumatic brain injury (TBI) in mice and other mammals. However, there are important gaps in our understanding of the neuropathology underlying repetitive blast exposure in animal models compared to the neuroimaging abnormalities observed in blast-exposed veterans. Moreover, how an increase in the number of blast exposures(More)
Neurotrophins, essential regulators of many aspects of neuronal differentiation and function, signal via four receptors, p75, TrkA, TrkB and TrkC. The three Trk paralogs are members of the LIG superfamily of membrane proteins, which share extracellular domains consisting of leucine-rich repeat and C2 Ig domains. Another LIG protein, LINGO-1 has been(More)
Two patients with giant cell arteritis (GCA) had a malignant course despite aggressive immunosuppressive therapy. A 63-year-old woman presented with symptoms of headache, jaw claudication, scalp paresthesia, and visual disturbances. A temporal artery biopsy showed GCA. While on prednisone, she suffered ischemic strokes, and serial cerebral angiograms(More)
