Accumulation of ubiquitinated proteins in inclusions is common to various neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease and amyotrophic lateral sclerosis, although it occurs in selective neurons in each disease. The mechanisms generating such abnormal aggregates and their role in neurodegeneration remain unclear. Inclusions(More)
Tumor necrosis factor alpha, granulocyte colony-stimulating factor, granulocyte/macrophage colony-stimulating factor, and formyl peptide were each found to cause a twofold increase in expression of CD14 on the surface of polymorphonuclear leukocytes (PMN). Upregulation of CD14 was complete by 20 min and thus appeared to result from expression of preformed(More)
This study investigated vocal cues that differentiate sarcastic utterances from non-sarcastic utterances. Utterances were drawn from videotapes of participant interviews and arranged on a master tape for analysis. Utterances that were identified as sarcastic by speakers and recognized as sarcastic by listeners were randomly arranged with utterances(More)
Evidence suggests that vascular endothelial growth factor (VEGF) mediates neuroprotection to prevent an apoptotic cell death. The p38 mitogen-activated protein kinase (MAPK) pathway is implicated as an important mediator of neuronal apoptosis but its role in VEGF-mediated neuroprotection is unclear. Herein, we show that treatments with the p38 MAPK(More)
The immune response of the CNS is a defense mechanism activated upon injury to initiate repair mechanisms while chronic over-activation of the CNS immune system (termed neuroinflammation) may exacerbate injury. The latter is implicated in a variety of neurological and neurodegenerative disorders such as Alzheimer and Parkinson diseases, amyotrophic lateral(More)
This study examined how relational type and empathy affect the use of sarcasm. We paired interviewers of high and low empathy with either an interviewee who was closely related or a stranger. Interviewers were given 10 questions to ask the interviewee, alternating sarcastic questions with sincere questions. Following each interview, participants completed(More)
Using a neuronal model of serum starved SK-N-SH neuroblastoma cells, we showed previously that the phosphorylation of Akt and the mTOR substrates S6K and S6 through the vascular endothelial growth factor receptor VEGFR2 was enhanced by treatments with the phosphatase PP2A inhibitor okadaic acid (OA). These findings suggested that PP2A inhibition uncouples(More)
The effects of variations in speaker rate and pitch on listener recall were studied. One hundred and twenty participants listened to an audiotape of one of two individuals speaking in one of four different styles--low variation in both rate and pitch, variation in rate but not in pitch, variation in pitch but not in rate, and variation in both rate and(More)
