A DNA-activated protein kinase (DNA-PK) was purified from nuclei of HeLa cells. Activity was associated with a single high-molecular-mass (approximately-300,000 Da) polypeptide when analyzed by gel filtration, denaturing polyacrylamide gel electrophoresis, and Western immunoblotting using a monoclonal antibody that also inhibits enzyme activity. Nuclear(More)
INTRODUCTION Severe hyponatremia is a serious medical condition that is associated with morbidity and mortality. Controversy still exists regarding the prevalence, cause and mortality of hyponatremia. PATIENTS AND METHODS Of the hyponatremic patients, we studied 116 severe hyponatremic patients. Severe hyponatremia was defined as a serum sodium(More)
Patients with end-stage renal disease (ESRD) exhibit immune dysregulation, but the precise immunological profile and the effect of hemodialysis (HD) on it has not been investigated fully. Thirty-eight ESRD patients (22 on HD and 16 in pre-dialysis) and 24 healthy volunteers were included. We compared the T cell immune profiles as in these patients. Among(More)
BACKGROUND/AIMS Chronic hepatitis B infection is a common cause of secondary membranous nephropathy (MN) in endemic areas. Lamivudine treatment improves renal outcome in patients with hepatitis B virus-associated MN (HBV-MN), but prolonged use leads to the emergence of lamivudine-resistant variants. We describe our experience treating lamivudine-resistant(More)
The present study investigated the clinical usefulness of plasma real-time polymerase chain reaction (PCR) (plasma-PCR) in the prevention of BK virus-associated nephropathy (BKVAN). First, we investigated the diagnostic value of plasma BK-PCR, urine BK-PCR, and urine cytology for the prediction of BKVAN retrospectively. Then we designed a prospective study(More)
BACKGROUND In this study, we assessed whether red blood cell distribution width (RDW) was associated with all-cause mortality in patients on peritoneal dialysis (PD) and evaluated its prognostic value. METHODS This study included 136 patients who had RDW levels at PD initiation from January 2007 to January 2014 at the Presbyterian Medical Center and Seoul(More)
BACKGROUND Chronic active antibody-mediated rejection (CAMR) is an important cause of chronic kidney allograft dysfunction, but there has been no effective treatment protocol established for it. METHODS Six renal transplant recipients who showed progressive deterioration in graft function and CAMR as diagnosed by biopsy were enrolled. We administered a(More)
Plasma cell infiltration into a renal allograft comprises a spectrum of lesions from acute rejection to posttransplant lymphoproliferative disease. We report an unusual case of plasma cell infiltration into a renal allograft with monoclonal gammopathy. A 42-year-old woman was admitted because of graft dysfunction after noncompliance with immunosuppressive(More)
BACKGROUND There are no definite guidelines about donation among prospective donors with asymptomatic urinary abnormalities. We evaluated the pathology of prospective kidney donors with asymptomatic urinary abnormalities and assessed the clinical outcomes of their organs. METHODS We reviewed the medical records of 15 prospective kidney donors who(More)
The aim of this study is to investigate the clinical significance of the ratio between interleukin-17 (IL-17) secreting cell and FOXP3-positive regulatory T cell (FOXP3(+) Treg) infiltration in renal allograft tissues with acute T-cell-mediated rejection (ATCMR). Fifty-six patients with biopsy-proven ATCMR were included. Infiltration of FOXP3(+) Treg and(More)
