The purpose of this study is to evaluate whether steady-state evoked potential (SSEP) can be used for objective estimation of auditory thresholds in patients with noise-induced hearing loss (NIHL). Eleven subjects (22 ears) with a characteristic audiometric notch between 3000 and 6000 Hz participated in this study. Both pure-tone thresholds and SSEP(More)
Bacterial meningitis, a world-wide disease, has to be reviewed periodically because the specific micro-organisms responsible for the infection vary with time, geography and patient age. To determine its incidence and clinical features in Taiwan, we reviewed the microbiological records for cerebrospinal fluid (CSF) and blood cultures, and the medical records(More)
This study was to determine whether polymorphisms of heat shock protein 70-1 (HSP70-1) and tumor necrosis factor alpha (TNF-alpha) are associated with the risk of Alzheimer's disease (AD) and vascular dementia (VaD). Using the criteria of the NINCDS-ADRDA and NINDS-AIREN, 125 AD patients, 57 VaD patients and 109 ethnically matched nondemented controls were(More)
Accumulation of mitochondrial DNA (mtDNA) mutations in human tissues has been associated with intrinsic aging and environmental insult. Recently, mtDNA mutations have been detected in various tumors, including head and neck tumors. However, the factors affecting the occurrence and accumulation of mtDNA deletions in tumor tissues are poorly understood. In(More)
Plasma endotoxin levels were investigated using a quantitative Limulus assay in patients with chronic liver diseases and correlated with the severity of liver diseases, the presence of esophageal varices, and hemodynamic parameters. The plasma endotoxin levels were significantly higher in chronic hepatitis patients with acute exacerbation (10.1 +/- 1.3(More)
The thermal stability of IL-1 beta in aqueous solution as a function of temperature (5-60 degrees C), pH (2-9), buffer (acetate, citrate, tris, and phosphate), and cyroprotectants (sugars, HSA) was investigated in this study. The analytical methodologies included RP-HPLC, SEC, ELISA, IEF-PAGE, SDS-PAGE, and bioassay. The degradation and inactivation of IL-1(More)
OBJECTIVE Our purpose was to depict the characteristics of the global vasculature of cervical lymphadenopathies and to clarify the efficiency of Doppler spectral analysis and power Doppler sonography in the differential diagnosis. SUBJECTS AND METHODS Prospectively, 289 lymph node lesions underwent Doppler flow studies and were grouped as metastasis,(More)
Bacterial meningitis is a common cause of profound deafness and, hence, a common cause of deafness in published series of patients treated with a cochlear prosthesis. Labyrinthitis ossificans is a common finding in meningogenic labyrinthitis and has been considered a relative contraindication to cochlear implantation. In the present study, the numbers of(More)
Lipoproteins and vascular factors may play roles in the development of Alzheimer's disease (AD) and/or vascular dementia (VaD). In this study, odd ratios (ORs) and 95% confidence intervals (CIs) for apolipoprotein E (APOE), angiotensin-converting enzyme (ACE), and kallikrein (KLK1) polymorphisms were computed to test their association with the disease by a(More)
BACKGROUND AND PURPOSE This study examines whether angiotensin-converting enzyme (ACE) gene polymorphisms are associated with the risk of spontaneous deep intracerebral hemorrhage (SDICH) in Taiwan using a case-control study. METHODS Totally, 217 SDICH patients and 283 controls were recruited. Associations of ACE A-240T and ACE I/D polymorphisms with(More)
