BACKGROUND It is still not clear which factors are associated with left ventricular mass index (LVMI) in chronic kidney disease (CKD) patients, based on the patient's physical and biochemical parameters at the time of echocardiography. The objective of the present study was to identify factors associated with LVMI in CKD patients (predialysis patients),(More)
Chronic inflammation promotes the progression of diabetic nephropathy (DN). However, the role of TNF-α remains unclear. The objectives of the present study were to examine whether TNF-α inhibition with a soluble TNF receptor (TNFR)2 fusion protein, i.e., etanercept (ETN), improves the early stage of DN in the type 2 diabetic model of the KK-A(y) mouse and(More)
BACKGROUND This longitudinal study is the first report on the factors associated with change rates of the estimated glomerular filtration rate (eGFR) and left ventricular mass index (LVMI) using echocardiography in chronic kidney disease (CKD) patients. METHODS Measurements of biochemical and physical values, and LVMI evaluated by echocardiography were(More)
The current study aimed to examine whether the levels of TNF receptors 1 and 2 (TNFR1 and TNFR2) in serum and urine were associated with other markers of kidney injury and renal histological findings, including TNFR expression, in IgA nephropathy (IgAN). The levels of the parameters of interest were measured by immunoassay in 106 biopsy-proven IgAN patients(More)
BACKGROUND It is very important to evaluate atherosclerosis at an early stage since cardiovascular disease is the main cause of death in patients with end stage renal disease. The purpose of our study was to examine which of the following parameters of atherosclerosis is the best index for the prediction of cardiovascular death or events in hemodialysis(More)
Exercise is recommended for the management of type 2 diabetes, but its effects on diabetic nephropathy (DN) are still unknown. We hypothesized that appropriate exercise improves early DN via attenuation of inflammation and oxidative damage. Type 2 diabetic KK-A(y) mice, a spontaneous DN model, underwent two different kinds of exercise (i.e., moderate and(More)
BACKGROUND/AIMS Previous studies have shown the presence of high levels of glycoxidation and lipid peroxidation products in association with atherosclerosis in patients with end-stage kidney disease. Acetates are commonly used buffer for correcting metabolic acidosis in hemodialysis (HD) patients. Since the toxic effects of acetates are well established,(More)
Rac1, a GTPase of the Rho subfamily, has a crucial role in cytoskeletal architecture, as well as the regulation of cell migration and growth. However, renal injury in mice with podocyte-specific deletion of Rac1 has yet to be elucidated fully due to conflicting findings. Herein, we identified a possible role for Rac1 in podocytes of streptozotocin- (STZ)(More)
