Induced pluripotent stem (iPS) cells can be established from somatic cells. However, there is currently no established strategy to generate corneal epithelial cells from iPS cells. In this study, we investigated whether corneal epithelial cells could be differentiated from iPS cells. We tested 2 distinct sources: human adult dermal fibroblast (HDF)-derived(More)
The case of a patient with severe left main trunk disease is presented, in which spasm of the right coronary artery resulted in intraoperative myocardial ischemia and perioperative myocardial infarction. It is suggested that coronary spasm may be a cause of perioperative myocardial infarction, and has to be considered in case of unknown etiology.
A 59-year-old man had a first myocardial infarction in the right coronary artery, followed by an another infarction in the left anterior descending coronary artery. Coronary thrombolysis for both occasions of acute myocardial infarction was successfully performed without severe residual stenosis. In the chronic phase after the second myocardial infarction,(More)
No aneurysm of the aortic valve associated with infective endocarditis has yet been reported. This report describes the clinical echocardiographic and pathologic findings in a patient who developed infective endocarditis resulting in aneurysm of the non-coronary cusp with aortic regurgitation. Surgical treatment was performed because of gradual expansion of(More)
Supine ergometer exercise test was performed in 10 healthy subjects and 9 patients who had severe stenosis in the left anterior descending coronary artery [5 patients with stenosis proximal to the septal perforator (proximal LAD disease) and 4 patients with stenosis distal to the septal perforator (distal LAD disease)]. In healthy subjects and patients with(More)
We previously established a spermatogonial transplantation model in fish using triploid recipients. Although triploid salmonids are sterile, they carry a limited number of immature triploid germ cells that potentially compete with the donor-derived germ cells for their niche. We therefore assessed the biological characteristics of germ cell-deficient gonads(More)
While using the balloon-on-a wire device, we experienced a case of difficult deflation of the Probe balloon system. Blockage of the balloon system was possibly caused by twisting the system to reach and pass the lesion in the branch of left circumflex coronary artery. The duration of inflation was 20 min, causing prolonged ischemia.
A 53-year-old woman presented with symptoms of dyspnea on exertion and edema of lower extremities. Chronic cardiac tamponade caused by the rupture of the right atrial wall was diagnosed by two-dimensional contrast echocardiography. Autopsy findings revealed primary cardiac hemangiopericytoma.
We report on an unusual patient with a threatened occlusive dissection, in whom prolonged (48-hr) inflation of a balloon catheter with localized heparin infusion proved successful. This intracoronary infusion catheter maintained distal coronary flow on a unique spiral coil design, and may provide an alternative or a bridge to emergency operation or stent(More)
