We conducted and evaluated a 4-year, web-based wellness program involving 2498 global employees. The program was designed to encourage improvement in diet, exercise level, and weight control. Each month, after enrollment, participants were prompted to log on and enter personal data. Four years' worth of nonparametric data were analyzed. Seventy-seven(More)
High-resolution magnetic resonance imaging (MRI) with flow suppression not only provides useful information on luminal and wall areas of the carotid artery but also can identify the principal tissue components of the carotid atherosclerotic plaque. The effects of intensive lipid-lowering therapy on these MRI tissue characteristics were examined in patients(More)
Immunization against extracellular neurotoxic proteins has shown promise in the treatment of several neurodegenerative disorders. We sought to determine whether immunization against mutant huntingtin, the intracellular protein that causes Huntington's disease (HD), could slow disease progression in the HD mouse model HDR6/2. DNA vaccination was used to(More)
High-resolution MRI may be used to monitor the progression of human carotid atherosclerosis by measuring the lumen and wall area changes over time. The purpose of this study was to analyze the precision of quantitative measurements of lumen and wall areas. Two independent MR scans near the carotid bifurcation were conducted on eight patients within 2 weeks.(More)
Little is known about the mechanism and signal transduction by LPS-mediated immunomodulation of murine peritoneal macrophages. It is found that the signal molecules of the down-stream of Ras, Raf-1, MAPK p44, and MAPK p42 are phosphorylated, and cPLA2 is activated with a significant increase of the release of [ H3 ] AA by macrophages in response to LPS and(More)
A 22-year-old man presented with a 3-month history of back pain and numbness of the left lower extremities. Lumbar spine MRI demonstrated conus enlargement and an intramedullary mass of predominant isointensity, heterogeneity with central necrosis, and marked heterogeneous enhancement (figure 1). The tumor was resected and was consistent with a glioblastoma(More)
The locus coeruleus (LC) is an important brainstem area involved in cocaine addiction. However, evidence to elucidate how cocaine modulates the activity of LC neurons remains incomplete. Here, we performed whole recordings in brain slices to evaluate the effects of cocaine on the sodium (Na+), potassium (K+), calcium (Ca2+) channels, and glutamatergic(More)
A novel cobalt-tetraphenylporphyrin/reduced graphene oxide (CoTPP/RGO) nanocomposite was prepared by a π-π stacking interaction and characterized by ultraviolet-visible absorption spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR) and electrochemical impedance spectroscopy (EIS). The CoTPP/RGO nanocomposite exhibited high electrocatalytic(More)
Assays with the ability to detect multiple antibodies in parallel have a wide range of potential applications in epidemiologic research. Here, a multiplex enzyme-linked immunosorbent assay-based protein array (ELISA-array) was developed to simultaneously detect five Flaviviridae infections. The platform was based on an indirect ELISA and 15 antigens were(More)
