BACKGROUND Peritoneal mesothelial cells play an important role in peritoneal dialysis and are often exposed to dialysis fluid containing high glucose levels. Loss of peritoneal function is a major complication associated with long-term peritoneal dialysis. In this study, we hypothesized that high glucose levels induce apoptosis, and that insulin attenuates(More)
BACKGROUND Although systemic hypertension is closely associated with aortic aneurysm (AA) formation, there are many patients with AA without hypertension. In these patients, an inflammation-mediated progression of aneurysmal disease is likely responsible for AA growth and eventual rupture. Unfortunately, there remains no reproducible and durable small(More)
AIMS Excessive vascular remodelling leads to progression of a wide range of vasculopathies, and the immune response to intimal injuries is crucial in this process. This vascular remodelling occurs in the hypoxic microenvironment and is closely related to the immune system. Macrophages play a key role in immunological-cell-mediated arterial remodelling. In(More)
AIM Ezetimibe, an inhibitor of cholesterol intestinal absorption, is a lipid lowering agent. However, anti-atherogenic effects of ezetimibe have not been fully elucidated. Therefore, the objective in this study was to clarify the vascular protective effects of ezetimibe in patients with hypercholesterolemia. METHODS Ezetimibe was administered to 20(More)
BACKGROUND The optimal medical management to delay the progression of aortic aneurysms has not been fully clarified, and the only standard treatment at present is antihypertensive therapy. Previous studies have shown beneficial effects of selective mineralocorticoid receptor (MR) antagonists on cardiovascular remodeling. The aim of the present study was to(More)
OBJECTIVES To investigate the effects of human umbilical cord blood-derived mononuclear cell (hUCB-MNC) transplantation on pulmonary hypertension (PH) induced by monocrotaline (MCT) in immunodeficient mice and their distribution. METHODS MCT was administered to BALB/c Slc-nu/nu mice, and PH was induced in mice 4 weeks later. Fresh hUCB-MNCs harvested from(More)
Oxidized cholesterols (oxycholesterols) in food have been recognized as strong atherogenic components, but their tissue distributions and roles in cardiovascular diseases remain unclear. To investigate whether accumulation of oxycholesterols is linked to cardiac morphology and function, and whether reduction of oxycholesterols can improve cardiac(More)
