Residual oil fly ash (ROFA) is a chemically complex mixture of compounds, including metals that are potentially carcinogenic because of their ability to cause oxidative injury. In this study, we investigated the association between exposure to particulate matter with an aerodynamic mass median diameter <or= 2.5 micro m (PM2.5) and oxidative DNA damage and(More)
BACKGROUND A critical question regarding the association between short-term exposure to ozone and mortality is the extent to which this relationship is confounded by ambient exposure to particles. OBJECTIVES We investigated whether particulate matter < 10 and < 2.5 microm in aerodynamic diameter (PM(10) and PM(2.5)) is a confounder of the ozone and(More)
Accumulating evidence demonstrates that particulate air pollutants can cause both pulmonary and airway inflammation. However, few data show that particulates can induce systemic inflammatory responses. We conducted an exploratory study using microarray techniques to analyze whole-blood total RNA in boilermakers before and after occupational exposure to(More)
Glomerulonephritis and pulmonary hemorrhage are features of Goodpasture's syndrome. Goodpasture's syndrome accompanied with central nervous system (CNS) vasculitis is extremely rare. Herein, we report a rare case of CNS vasculitis associated with Goodpasture's syndrome in a 34-year-old man, who presented with a seizure and sudden onset of right sided(More)
The prognosis of myasthenia gravis (MG) has improved dramatically due to advances in critical-care medicine and symptomatic treatments. Its immunopathogenesis is fundamentally a T-cell-dependent autoimmune process resulting from loss of tolerance toward self-antigens in the thymus. Thymectomy is based on this immunological background. For MG patients who(More)
INTRODUCTION The aim of this study was to examine whether the patterns of diffusion-weighted imaging (DWI) abnormalities and quantitative regional apparent diffusion coefficient (ADC) values can predict the clinical outcome of comatose patients following cardiac arrest. METHODS Thirty-nine patients resuscitated from out-of-hospital cardiac arrest were(More)
OBJECTIVE To evaluate the interobserver variability and performance in the interpretation of ultrasonographic (US) findings of thyroid nodules. MATERIALS AND METHODS 72 malignant nodules and 61 benign nodules were enrolled as part of this study. Five faculty radiologists and four residents independently performed a retrospective analysis of the US images.(More)
A B-cell activating factor of the tumor necrosis factor (TNF) family (BAFF) is an essential B-cell survival factor. Myasthenia gravis (MG) is one of the most typical antibody-mediated autoimmune disorders. To test whether serum BAFF levels are increased in MG patients, we compared the serum BAFF levels of 40 MG patients with those of 30 healthy controls.(More)
BACKGROUND The natural course of cytologically benign thyroid nodules remains unclear. The aim of this study was to evaluate whether ultrasonographic (US) changes are associated with changes in nodule volume during follow-up. METHODS We retrospectively reviewed over 4 years of clinical records of patients with benign thyroid nodules as confirmed by fine(More)
BACKGROUND AND OBJECTIVE Neuromyelitis optica (NMO) is an inflammatory demyelinating disorder of the central nervous system with a relapsing and remitting course. We aimed to identify factors associated with the time to next attack, including the effect of the natural disease course and the diverse treatment regimens, by applying a longitudinal statistical(More)
