Duchenne muscular dystrophy (DMD) is a progressive muscle-wasting disease that causes respiratory or cardiac failure and results in death at about 20 years of age. An animal model of DMD, the mdx mouse, is commonly used to estimate dystrophic pathology. The pathological features of limb muscles are relatively mild, however the diaphragm is severely affected(More)
In order to investigate the mechanism of dystrophin localization in the central nervous system (CNS), we generated adenovirus vectors that contained minidystrophin or truncated minidystrophin cDNA. We infected a primary neuronal culture derived from mdx mouse hippocampus with these viruses. Minidystrophin was observed along the plasma membrane as punctate(More)
We report a case of sudden death due to variant angina during Holter electrocardiogram (ECG) monitoring. The patient, a 60-year-old man, had been aware of chest discomfort lasting less than one minute at midnight 2 days earlier. Because variant angina or arrhythmia was suspected, Holter ECG monitoring was performed. The patient spent a whole day without a(More)
Duchenne muscular dystrophy (DMD) is a fatal, progressive, muscle-wasting disease caused by defects in the dystrophin. No viral vector except the helper-dependent adenovirus vector (HDAdv) can package 14-kilobase (kb) full-length dystrophin complementary DNA (cDNA), and HDAdv is considerably safer than old-generation adenovirus vectors because of the(More)
Duchenne muscular dystrophy (DMD) is an inherited severe muscle wasting disorder with, thus far, no effective therapy. DMD causes respiratory and cardiac failure as well as muscle wastage. Among the various symptoms, respiratory insufficiency is a major cause of death in DMD patients at about 20 years of age. So, naturally, the improvement of respiratory(More)
We report the first adult case of Influenza A virus infection with acute unilateral oculomotor nerve palsy. Unlike previous reports, our patient showed isolated unilateral oculomotor nerve palsy as soon as she developed general symptoms with Influenza A infection, and demonstrated no significant increases of anti-ganglioside antibodies including anti-GQ1b(More)
A 64-year-old man visited our hospital with a complaint of exertional chest discomfort. Exercise electrocardiography revealed ST segment depression in the V4-V6 leads, and exercise thallium myocardial scintigraphy demonstrated myocardial ischemia in the area of the right coronary artery, suggesting effort angina. Diagnostic coronary angiography revealed an(More)
