BK polyomavirus (BKV) is ubiquitous in the human population, infecting children without obvious symptoms, and persisting in the kidney in a latent state. In immunosuppressed patients, BKV is reactivated and excreted in urine. BKV isolates have been classified into four subtypes (I-IV) using either serological or genotyping methods. To elucidate the subtypes(More)
Macrophages act to protect the body against inflammation and infection by engaging in chemotaxis and phagocytosis. In chemotaxis, macrophages use an actin-based membrane structure, the podosome, to migrate to inflamed tissues. In phagocytosis, macrophages form another type of actin-based membrane structure, the phagocytic cup, to ingest foreign materials(More)
BACKGROUND Although a close relationship between uraemic pruritus and serum calcium levels has been demonstrated for some time, the degree of pruritus was not always correlated with calcium concentrations. In the present study, we assessed calcium ion distribution in the skin of chronic haemodialysis patients with and without pruritus. METHODS We excluded(More)
To assess whether atrial natriuretic peptide (ANP) and arginine vasopressin (AVP) participate in impaired water excretion in patients with hypothyroid states (HS), an oral acute water loading (WL) test (20 ml/kg.BW/45 min) was performed before and after L-thyroxine (T4) treatment in 5 hypothyroid patients. Plasma ANP, AVP, osmolality (Posm), total protein(More)
INTRODUCTION The aortic calcification index (ACI) is reported to be closely associated with renal dysfunction and cardiovascular events; however, its implication in renal transplant recipients has not been well examined. In this study, we investigated the relationship between pretransplant ACI, ACI progression, post-transplant renal function, and(More)
Core2 β-1,6-N-acetylglucosaminyltransferase (C2GnT) forms an N-acetylglucosamine branch in the O-glycans (core2 O-glycans) of cell surface glycoproteins. We previously revealed that the expression of C2GnT is positively correlated with poor prognosis in prostate cancer patients. However, the detailed mechanisms underlying their poor prognosis remain(More)
The mechanism of te development of hemodialysis hyperlipidemia was investigated in uremic patients on maintenance hemodialysis. Hemodialysis treatment lost large amounts of carnitine from blood into the dialysate fluid, resulting in the reduction in serum concentration of carnitine. After the treatments were repeated for more than 12 months, the serum(More)
BACKGROUND Extended-release tacrolimus (TAC-ER) was developed to provide a more convenient treatment compliance and improve safety by avoiding toxic peak levels. We prospectively evaluated the safety and effectiveness of a 1:1 dose switch from twice-daily tacrolimus to once-daily TAC-ER in stable kidney transplant recipients and assessed their satisfaction(More)
The O-glycan branching enzyme, core2 β-1,6-N-acetylglucosaminyltransferase (C2GnT), forms O-glycans containing an N-acetylglucosamine branch connected to N-acetylgalactosamine (core2 O-glycans) on cell-surface glycoproteins. Here, we report that upregulation of C2GnT is closely correlated with progression of bladder tumours and that C2GnT-expressing bladder(More)
