Past attempts to grow human corneal epithelium in culture had limited success, with confluence rarely attained. This work is to determine whether different areas of human corneal epithelium grow better in tissue culture. We compared the extent, the mitotic rates, and morphology of outgrowths and histology of explants from central and peripheral human(More)
Peripheral human corneal epithelium grows better in tissue culture than central epithelium, but it is not known whether ocular limbal epithelium grows even better than does the peripheral corneal epithelium. In this work we compared the growth kinetics of limbal and peripheral human corneal epithelial cells in tissue culture. Four 1-2 mm2 explants, removed(More)
The residue value on dipole analysis (the ratio of non-dipolar component to the measured body surface potentials) was estimated mathematically in 16 patients with left bundle branch block. Patients were classified into those with (group A, nine patients) and those without (group B, seven patients) a perfusion defect on thallium-201 myocardial scintigraphy.(More)
We report a 23-year-old man who underwent coronary artery bypass grafting (CABG) for coronary aneurysms associated with Kawasaki disease using the left internal thoracic artery (LITA) and right gastroepiploic artery (RGEA) after a second myocardial infarction (MI). Preoperatively, this patient showed repetitive occlusion and recanalization of coronary(More)
PURPOSE To assess the effects of endovascular irradiation on vascular structure and function in pig coronary arteries in the absence of vascular injury. METHODS AND MATERIALS Vasomotor responses to contractions of KCl and prostaglandin F2alpha (PGF2alpha), relaxations to endothelium-dependent (substance P, A23187) and -independent (sodium nitroprusside,(More)
Tissue lenses for epikeratophakia are currently prepared by one of three different methods: cryolathing and storage in corneal preservation media; cryolathing and lyophilization; or non-freeze microkeratome cutting. It has been proposed that avoidance of the damage caused by freezing or lyophilization will speed healing and recovery of vision. We examined(More)
Background: Bone marrow-derived mononuclear cells (BM-MNCs) can give rise to endothelial progenitor cells and localized transplantation of BM-MNCs in ischemic myocardium may augment neovascularization. However, not much is known of the arrhythmogenic potential of BM-MNCs after intramyocardial transplantation. Objective: Evaluate the threshold for(More)
PURPOSE Endovascular irradiation inhibits neointimal hyperplasia in ballooned and stented arteries but impacts both diseased and adjacent normal tissue. Little is known about the effects of irradiation on downstream vasculature. In this study, we investigated vascular function and structure of pig coronary arteries distal to sites of endoluminal(More)
