Granulomatous interstitial nephritis (GIN) is a rare histologic diagnosis in renal allografts. We report three cases with GIN. Case 1: a 37-yr-old woman received a kidney from her mother. On follow-up 15 months later, serum creatinine was increased and a graft biopsy showed epithelioid granuloma in the center of massive mononuclear cell infiltration. She(More)
Palatinose is a disaccharide present in honey, which has the characteristics of delayed digestion and absorption. We developed a palatinose-based balanced formula (PBF) and reported its beneficial effects on metabolic syndrome-related parameters in rats. To examine the effects of PBF in humans, we here conducted a crossover study using twenty-three subjects(More)
A new method was developed for detection of human papillomavirus (HPV) by loop-mediated isothermal amplification (LAMP), which was compared with the polymerase chain reaction (PCR), and real-time PCR for specificity and sensitivity. All initial validation studies with the control DNA proved to be type-specific. In order to evaluate the reliability of HPV(More)
Systemic chemotherapy based on 5-fluorouracil (5-FU) is a standard treatment for unresectable or recurrent large intestinal cancer. Although hyperammonemia is a known side effect of 5-FU that can cause serious pathological conditions, only a few cases have been reported. We describe 4 cases of 5-FU-related hyperammonemia with impairment of consciousness in(More)
Recent progress in regenerative medicine has enabled the utilization of pluripotent stem cells (PSCs) such as embryonic stem cells (ESCs) as a donor resource for transplantation. However, immune suppression is still needed when the donor-recipient combination is allogeneic. Protection of ESCs-derived grafts from host immune response might be achieved(More)
BACKGROUND Induced pluripotent stem cell (iPSC) technology provides new opportunities in regenerative medicine to generate grafts from donors for transplantation. However, particularly when allogeneic iPSCs are used, immune suppression is required to avoid rejection of iPSC-derived grafts. In this study, we examine a concept that protection of iPSCs-derived(More)
OBJECTIVE To obtain accurate disease staging, we routinely perform regional lymph node dissection (LND) in conjunction with laparoscopic nephroureterectomy (NU) to treat urothelial carcinoma of the upper urinary tract. The present study evaluated the feasibility and usefulness of LND in laparoscopic NU. PATIENTS AND METHODS Thirty-nine patients undergoing(More)
AIM Recurrence of immunoglobulin A (IgA) nephropathy (IgAN) after renal transplantation is important as a cause of graft failure under improving rejection control. However, no specific therapy for recurrent IgAN is currently available. In this study, we evaluated the histological efficacy of tonsillectomy for allograft IgAN. METHODS Fifteen kidney(More)
Calcineurin inhibitors (CNIs) have considerably improved renal allograft survival. However, their chronic use has various adverse effects, including hypertension, hyperlipidemia, and nephrotoxicity. We conducted a retrospective study of kidney transplant recipients using a CNI withdrawal protocol. Eleven of 13 patients who had stable graft function on(More)
We evaluated the correlation between the conventional manual serological testing method for syphilis and a novel automated serological testing method and between six different reagents used in the automated method. Twenty-six serum samples, which were positive on non-treponemal manual serological testing, were obtained from 19 patients with early syphilis.(More)
