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)
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)
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)
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)
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.
A set of 1,3-propanediamine derivatives connected to carbohydrates (5) has been prepared in four steps from peracetylated sugar and 1,3-dibromo-2-propanol in 60-73% yields. D-Glucose, D-mannose, D-galactose, D-xylose, D-ribose, and maltose are utilized as sugar molecules in this work. The diamine moiety was connected to the C1 carbon of the glycopyranose(More)
