BACKGROUND Circulating tumor cells (CTCs) have been shown to aid in the therapeutic management of patients. But, only a few attempts have been made at the detection of urothelial cancer cells in the blood. The purpose of this study was to test the hypothesis that CTCs are detected in patients with urothelial cancers using newly developed CellSearch Assay.(More)
Many mechanisms involving TNF-alpha, Th1 responses, and Th17 responses are implicated in chronic inflammatory autoimmune disease. Recently, the clinical impact of anti-TNF therapy on disease progression has resulted in re-evaluation of the central role of this cytokine and engendered novel concept of TNF-dependent immunity. However, the overall relationship(More)
OBJECTIVES To determine the accuracy of orchidometry and ultrasonography for measuring the testicular volume by comparing the resultant measurements with the actual testicular volume in humans. METHODS The testicular volume of 40 testes from 20 patients with prostate cancer (mean age +/- SD 74.5 +/- 7.5 years) was measured using the Prader orchidometer(More)
AIM To evaluate the relationship between testicular function and testicular volume measured by using Prader orchidometry and ultrasonography (US) to determine the critical testicular volume indicating normal testicular function by each method. METHODS Total testicular volume (right plus left testicular volume) was measured in 794 testes in 397 men with(More)
The effect of water percolation on CH4 emission from rice paddies was investigated using a lysimeter experiment for 4 years. Water percolation rates of the lysimeters were adjusted to one of three values, about 0, 5, or 20 mm day-1, during the cultivation periods of the first 3 years by periodically opening water stopping valves installed at the bottom of(More)
OBJECTIVES To determine the prevalence of testicular microlithiasis (TM) seen by testicular ultrasonography (US) in Japanese adult men referred for andrologic symptoms and evaluate associations of TM with pathologic conditions. METHODS For 7 years, US was performed in 969 patients (mean age 40.9 years) at one institution. The patients were divided into(More)
OBJECTIVE To report a patient with azoospermia who achieved an induction of spermatogenesis after undergoing orchiopexy of long-standing bilateral traumatic dislocated testes. DESIGN Case report. SETTING Clinical. PATIENT(S) A 33-year-old man. INTERVENTION(S) Imaging studies, orchiopexy, testicular biopsy, and a review of similar cases. MAIN(More)
BACKGROUND The increase of bone mineral density in cortical bone after parathyroidectomy is smaller than that in cancellous bone. Changes of serum bone markers reflect those of bone metabolism both in cortical and cancellous bone after parathyroidectomy. The present study was undertaken to investigate changes of histomorphometric parameters of cortical and(More)
OBJECTIVES To compare the accuracy of testicular volume measurements with the Prader orchidometer versus ultrasonography. METHODS The volume of 938 testes in 469 men with infertility (mean age 35.8 years) was measured using a Prader orchidometer and by ultrasonography. The ultrasound testicular volumes were calculated using the formula length x width x(More)
The objective of this study was to evaluate the utility of the Hounsfield Unit (HU) values as a predictive factor of extracorporeal shock wave lithotripsy outcome for ureteral and renal stones. We also assessed the possibility that HU values could be used to predict stone composition. A retrospective study was performed to measure stone HU values in 260(More)
