Although germline cells can form multipotential embryonic stem (ES)/embryonic germ (EG) cells, these cells can be derived only from embryonic tissues, and such multipotent cells have not been available from neonatal gonads. Here we report the successful establishment of ES-like cells from neonatal mouse testis. These ES-like cells were phenotypically(More)
Female human induced pluripotent stem cell (hiPSC) lines exhibit variability in X-inactivation status. The majority of hiPSC lines maintain one transcriptionally active X (Xa) and one inactive X (Xi) chromosome from donor cells. However, at low frequency, hiPSC lines with two Xas are produced, suggesting that epigenetic alterations of the Xi occur(More)
The incidental discovery of adrenal masses in radiologic imaging studies is becoming increasingly common. Herein we present our experience with 59 cases of incidentally discovered and surgically removed adrenal masses. Of 59 adrenal incidentalomas, 15 cases were hypersecretory tumors, including 11 pheochromocytomas; only 3 were adrenocortical carcinomas.(More)
To find reliable biomarkers for high-grade malignancy, the relationship between immunohistochemical L-type amino-acid transporter 1 (LAT1) expression of biopsy samples, determined with the newly developed monoclonal antibody against human LAT1, and prognosis of patients with prostate cancer, was investigated. The intensity and score of immunohistochemical(More)
OBJECTIVE To study the prevalence of fluoroquinolone-resistant Escherichia coli before transrectal ultrasound (TRUS)-guided prostate biopsy and prospectively analyze the rates of infective complications after biopsy in patients receiving fluoroquinolone prophylaxis. E. coli is the pathogen most commonly associated with infections after TRUS-guided prostate(More)
BACKGROUND Lymphovascular invasion (LVI) identified following pathologic slide review has been shown to be an independent predictor of recurrence-free survival (RFS) and cancer-specific survival (CSS) in a multicenter series of patients undergoing radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UTUC). However, the validity of(More)
OBJECTIVES To present our preliminary clinical results of transrectal high-intensity focused ultrasound (HIFU) in Stage T1b-2N0M0 prostate cancer. Efforts are being made to provide minimally invasive alternative treatment options with equal efficacy and fewer side effects. HIFU delivers ultrasound energy with rapid thermal necrosis of tissue in the focal(More)
PURPOSE The Japanese Urological Association, and Japanese Society of Endourology and ESWL have established the Endoscopic Surgical Skill Qualification System in urological laparoscopy. The system consists of a urological section as well as gynecology and general surgery sections. We present details of the Endoscopic Surgical Skill Qualification System and(More)
We report a multicenter trial with transrectal high-intensity focused ultrasound (HIFU) in the treatment of localized prostate cancer. A total of 72 consecutive patients with stage T1c-2NOM0 prostate cancer were treated using the Sonablate 500TM HIFU device (Focus Surgery, Indianapolis, USA). Biochemical recurrence was defined according to the criteria(More)
OBJECTIVES To determine the expression patterns and prognostic value of S100A2 and S100A4 in surgical specimens from radical cystectomy for transitional cell carcinoma of the urinary bladder. METHODS Immunohistochemical staining for S100A2 and S100A4 was performed in 92 archived radical cystectomy and 38 normal specimens. The immunoreactivity of these(More)
