INTRODUCTION A nationwide survey was conducted to investigate the prevalence of upper urinary calculi in Taiwan. MATERIALS AND METHODS A postal questionnaire was mailed to 27,758 people, 0.2% of the adults in Taiwan. RESULTS Of the 4,588 valid respondents, 440 had at least one episode of upper urinary calculus disease. The overall prevalence was 9.6%(More)
OBJECTIVES To conduct a prospective and randomized trial to compare the efficiency quotient and cost-effectiveness index of shock wave lithotripsy (SWL) and ureteroscopic lithotripsy (URSL) for the treatment of large upper third ureteral stones. METHODS A total of 35 male patients and 7 female patients with a solitary, radiopaque upper ureteral stone, 15(More)
An ethnomedically-driven approach was used to evaluate the ability of a pure compound isolated from the creosote bush (Larrea tridentata) to lower plasma glucose concentration in two mouse models of type 2 diabetes. The results indicated that plasma glucose concentration fell approximately 8 mmol/l in male C57BL/ks-db/db or C57BL/6J-ob/ob mice following the(More)
The purpose of the study was to develop a mouse model of non-insulin-dependent diabetes mellitus (NIDDM) that closely simulates the metabolic abnormalities of the human disease and is also cost-effective compared with the genetic models currently available. For this purpose, insulin resistance was induced in male C57BL/6J or Institute of Cancer Research(More)
The effect of sertraline, an antidepressant, on cytosolic-free Ca(2+) levels ([Ca(2+) ](i) ) in human cancer cells is unclear. This study examined whether sertraline altered basal [Ca(2+) ](i) levels in suspended PC3 human prostate cancer cells by using fura-2 as a Ca(2+) -sensitive fluorescent probe. At concentrations of 10-150 μM, sertraline induced a(More)
Evidence has been published that a wide array of plant-derived active principles, representing numerous classes of chemical compounds, demonstrate activity consistent with their possible use in the treatment of patients with Type 2 diabetes mellitus (DM). Despite these interesting observations, to date, metformin is the only ethical drug approved for(More)
The effect of N-(4-hydroxyphenyl) arachidonoyl-ethanolamide (AM404), a drug commonly used to inhibit the anandamide transporter, on intracellular free Ca2+ levels ([Ca2+]i) and viability was studied in human MG63 osteosarcoma cells using the fluorescent dyes fura-2 and WST-1, respectively. AM404 at concentrations > or = 5 microM increased [Ca2+]i in a(More)
BACKGROUND The expression of vascular endothelium growth factor (VEGF) has been correlated to the grading and stage of prostate cancers. However, data regarding Taiwanese prostate cancer patients are lacking. The aim of the present study was to examine VEGF expression in our radical prostatectomy specimens. METHODS Fifty-one radical prostatectomy(More)
The aim of this study was to examine the feasibility of ureteroscope-assisted double-J stenting following laparoscopic ureterolithotomy and to evaluate the effects of retrograde ureteroscopic access exerted on the sutured ureterotomy site. From January 2002 to December 2011, 30 patients with proximal ureteral stone underwent ureteroscopic double-J stenting(More)
The effect of calmidazolium on cytosolic free Ca2+ concentrations ([Ca2+]i) and viability has not been explored in human hepatoma cells. This study examined whether calmidazolium altered [Ca2+]i and caused cell death in HA59T cells. [Ca2+]i and cell viability were measured using the fluorescent dyes fura-2 and WST-1, respectively. Calmidazolium at(More)
