BACKGROUND A new histopathological classification of anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis was recently proposed. We evaluated the predictive value of this classification for renal outcome in Japanese patients. METHODS We enrolled 122 patients with ANCA-associated glomerulonephritis diagnosed at several institutions in(More)
Congenital malignant gliomas are rare brain tumors about which few reports have been published. We present the clinical course and genetic alterations in an infant with a congenital malignant glioma detected incidentally by ultrasonography at 36 weeks. The tumor occupied the right temporoparietal region, extended to the posterior fossa, and significantly(More)
AIMS Inflammation and possibly hypoxia largely affect glucose utilization in atherosclerotic arteries, which could alter many metabolic systems. However, metabolic changes in atherosclerotic plaques remain unknown. The present study aims to identify changes in metabolic systems relative to glucose uptake and hypoxia in rabbit atherosclerotic arteries and(More)
AIM To examine the association between renal vasculature changes and generalized atherosclerosis using autopsy cases. METHODS We histologically examined 107 autopsy patients(mean age, 68.4 years; 64% men; 81% non-CVD) to investigate the association between renal vasculature changes and generalized atherosclerosis. We measured the intima/media(I/M) ratio(More)
BACKGROUND Ultrasound-determined carotid intima-media thickness (IMT) is widely used as an indicator of generalized atherosclerotic burden, but there are limited autopsy findings in support of the association, directly. METHODS We performed an autopsy analysis (n = 111, mean 68.8 years; 65.0% men; 86% non-cardiovascular disease death) to examine the(More)
Intrauterine growth restriction (IUGR) is the leading cause of fetal mortality and morbidity. As an etiology, each of placental findings, maternal factors and fetal factors has been reported to be associated with IUGR, although a comprehensive approach to examine all of these parameters as a cause of IUGR has not been reported. In the present study,(More)
BACKGROUND Imaging modalities to assess atherosclerotic plaque thrombogenicity have not been established, so in this study the relationship between [(18)F]-fluorodeoxyglucose ((18)F-FDG) uptake and thrombus formation was investigated in rabbit atherosclerotic arteries. METHODS AND RESULTS Atherosclerotic plaque was induced in the iliacofemoral artery by(More)
AIM Patients with peripheral artery disease (PAD) have a high prevalence of cardiovascular morbidity and mortality; however, majority of patients with PAD are asymptomatic. This study aimed to histologically evaluate whether asymptomatic, lower extremity artery plaques are associated with systemic atherosclerosis and the onset of cardiovascular disease(More)
BACKGROUND High plasma levels of C-reactive protein (CRP) constitute a powerful predictive marker of cardiovascular events. Several lines of evidence suggest that CRP has prothrombogenic effects. However, whether CRP directly participates in the pathogenesis of thrombosis in vivo has not been fully clarified. OBJECTIVE To test whether human CRP (hCRP)(More)
