BACKGROUND Hepcidin is a central regulator of iron homeostasis. Increased hepcidin concentrations could cause iron-restricted erythropoiesis in chronic kidney disease (CKD)-associated anemia. This cross-sectional observational study was conducted to evaluate the association between hepcidin and CKD-associated anemia in non-dialysis CKD patients. METHODS A(More)
BACKGROUND Erythropoietin (EPO) has been found to have anti-apoptotic and tissue protective effects on the myocardium. The aim of the present pilot study was to observe the safety and efficacy of EPO administration for patients with acute myocardial infarction (AMI). METHODS AND RESULTS Patients admitted with AMI had all undergone successful percutaneous(More)
Effects of glyceryl trinitrate (GTN) and nitric oxide (NO) on the cardiac functions and myocardial cyclic GMP (cGMP) contents were examined in comparison with those in the aorta and correlated with myoglobin (an inhibitor of soluble guanylate cyclase) contents using the preparations isolated from the reserpinized rabbit. GTN (10−10-10−4mol/l) produced a(More)
BACKGROUND There have been a number of recent reports on the use of autologous bone marrow implantation (BMI) in the treatment of peripheral arterial disease, with a clinical response rate of approximately 70%. However, the factors that influence efficacy have not yet been clarified. We have analyzed the relationship between the number of implanted bone(More)
UNLABELLED Although various noninvasive methods have been used to detect vasospasm, none of them are sensitive enough for patients with sporadic attacks. Because abnormal fatty acid metabolism and cardiac adrenergic neuronal damage are observed in ischemic myocardium, (123)I-15-(p-iodophenyl)-3-R,S-methyl pentadecanoic acid (BMIPP) and(More)
Cardiomyocytes with myocarditis compared with the normal state are thought to change the expressions of various genes greatly, some of which may be new biomarkers or new biologic medicinal products. However, until now, little comprehensive analysis has been made of gene-expression changes in cardiomyocytes with myocarditis. In this study, we performed a DNA(More)
Etomoxir, an inhibitor of mitochondrial carnitine palmitoyltransferase-1, is known to attenuate the changes in myosin isoforms and sarcoplasmic reticular function that occur in diabetic rat hearts. In the present study, we tested the hypothesis that etomoxir also prevents the diabetes-induced depression of sarcolemmal (SL) Na+-K+ ATPase activity by(More)
IL-22 is one of several cytokines with limited homology to IL-10. However, the biological activities of IL-22 are mostly unknown. The purpose of this study was to evaluate the effect of IL-22 on rat experimental autoimmune myocarditis (EAM) and elucidate an aspect of the biological activities of IL-22. Rats were immunized on day 0; IL-22-Ig-treated rats(More)
The cardioprotective properties of quinapril, an angiotensin-converting enzyme inhibitor, were studied in a rat model of dilated cardiomyopathy. Twenty-eight days after immunization of pig cardiac myosin, four groups rats were given 0.2 mg/kg (Q0.2, n = 11), 2 mg/kg (Q2, n = 11) or 20 mg/kg (Q20, n = 11) of quinapril or vehicle (V, n = 15) orally once a(More)
Erythropoietin (EPO) has long been utilized for the treatment of renal anemia. The erythropoietin receptor (EPOR) is also expressed in the cardiovascular and central nervous systems in addition to an erythroid lineage, to provide an organoprotective role against several types of cellular stress. Pulmonary hypertension (PH) is a poor prognostic disease(More)
