PURPOSE To evaluate the diagnostic ability of diffusion-weighted imaging (DWI) and dynamic contrast-enhanced imaging (DCEI) in combination with T2-weighted imaging (T2WI) for the detection of prostate cancer using 3 T magnetic resonance imaging (MRI) with a phased-array body coil. MATERIALS AND METHODS Fifty-three patients with elevated serum levels of(More)
PURPOSE To retrospectively evaluate pleural disease on images from patients with autopsy-proved silicosis. MATERIALS AND METHODS The study had institutional review board approval, and informed consent from relatives of diseased subjects was waived. Lung specimens were obtained at autopsy in 110 men (mean age, 72 years) who had been followed up(More)
OBJECTIVE Positron emission tomography (PET) using (18)F-fluoro-2-deoxy-D -glucose (FDG) has a limitation in detecting cerebral metastases; however, the feasibility of detection by inline PET/computed tomography (CT) system remains unknown. We evaluated the accuracy of FDG-PET/CT of body imaging protocol for the detection of cerebral metastases when(More)
UNLABELLED Patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) often have metabolic disorders including insulin resistance and type 2 diabetes mellitus (T2DM). We clarified the predictive factors in glucose metabolism for progression of hepatic fibrosis in patients with NAFLD by the 75-g oral glucose tolerance test(More)
Negative psychological characteristics have been recognized as independent risk factors of cardiovascular disease (CVD). The purpose of this study was to evaluate the influence of depression and anxiety on cardiac autonomic function and endothelial function in healthy elderly subjects. Forty-six healthy elderly volunteers (mean age 60.8 years) were enrolled(More)
Yuzu (Citrus junos Tanaka) has been used as a traditional medicine in Japan. We investigated in vitro anti-inflammatory effects of limonene from yuzu peel on human eosinophilic leukemia HL-60 clone 15 cells. To examine anti-inflammatory effects of limonene on the cells, we measured the level of reactive oxygen species (ROS), monocyte chemoattractant(More)
OBJECTIVE The objective of our study was to evaluate serial CT changes from normal or near-normal lungs to honeycomb lungs in dust-exposed patients who developed chronic interstitial pneumonia. MATERIALS AND METHODS From the records of the national hospital for pneumoconiosis, we retrospectively identified patients with chronic interstitial pneumonia who(More)
We have found decreased serum alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) levels in human males exposed to toluene at low levels, suggesting that toluene exposure or related factors in lifestyles were likely to have lowering effects on serum ALT and GGT activities between toluene-exposed and the control subjects. The present study was(More)
BACKGROUND Oxidative stress is believed to play a crucial role in aging and age-related diseases, and is widely thought to increase morbidity and mortality in the elderly. Assessment of biomarkers of oxidative stress, such as 8-isoprostane and 8-hydroxy-2-deoxyguanosine, are considered to be useful in predicting disease risks at the population level. (More)
A sharp rise in the number of patients with infectious gastroenteritis was observed in the 25th week of year 1996 in the Takahashi-Ashin district by researchers with the Infectious Disease Surveillance Program for tuberculosis and other infectious diseases in the Okayama Prefecture. This sharp rise occurred coincidentally with an outbreak of(More)
