BACKGROUND Nitrates are widely used to treat coronary artery disease, but their therapeutic value is compromised by the rapid development of tolerance. Recently, the renin-angiotensin system has been suggested to play an important role in the development of nitrate tolerance. METHODS AND RESULTS Sixty-four patients with coronary spastic angina were(More)
We report the histopathologic findings of 3 sural nerve biopsies and 1 muscle biopsy from 3 patients with Rett syndrome. The 3 sural nerve biopsies demonstrated a few ultrastructural abnormalities, including the presence of many Pi-granules and mitochondrial changes in the cytoplasm of Schwann cells, occasional bands of Büngner and onion-bulb formations,(More)
Weak aortic media layers can lead to intimal tear (IT) in patients with overt aortic dissection (AD), and aortic plaque rupture is thought to progress to penetrating atherosclerotic ulcer (PAU) with intramural hematoma (IMH). However, the influences of shear stress and atherosclerosis on IT and PAU have not been fully examined. Ninety-eight patients with(More)

Introduction Moyamoya disease is a rare cerebrovascular occlusive disease of unknown etiology, characterized by stenosis or occlusion of both internal carotid arteries (ICAs) at the supraclinoid portion and an abnormal vascular network (moyamoya vessels)(1). 3-T MR angiography clearly shows moyamoya vessels at the base of the brain (2).
