conclusions preoperative diagnosis of spermatic cord leiomyosarcma is difficult and commonly made by histological examination and immunochemical staining. case presentation here we reported a 75-year-old man who presented with a painless lump in the right hemiscrotum. a right radical orchiectomy was performed. histopathology confirmed a neoplastic tissue with mesenchymal origin in spermatic cor...

BACKGROUND Standard electroanatomic mapping systems use a single catheter to perform left ventricular substrate mapping. A new mapping system uses a 64-electrode mini-basket catheter to perform rapid automated acquisition of chamber geometry, voltage, and activation. OBJECTIVE The aim of this study was to compare the accuracy of electroanatomic mapping using the basket catheter with that of m...

The pathophysiologic mechanisms behind urologic disease are increasingly being elucidated. The object of this investigation was to evaluate the publication policies of urologic journals during a period of progressively better understanding and management of urologic disease. Based on the ISI Web of Knowledge Journal Citation Reports and the PubMed database, the number and percentage of original...

BACKGROUND Different types of urologic cancers have been associated with colorectal cancer (CRC) in hereditary nonpolyposis CRC, but it is still unknown whether there is an association between urologic cancer and CRC in the general population. We sought to quantify the risk for CRC after urologic cancer and the risk for urologic cancer after CRC in patients without known genetic syndromes. ME...

A specific messenger ribonucleoprotein (RNP) particle, Balbiani ring (BR) granules in the dipteran Chironomus tentans, can be visualized during passage through the nuclear pore complex (NPC). We have now examined the transport through the nuclear basket preceding the actual translocation through the NPC. The basket consists of eight fibrils anchored to the NPC core by nucleoprotein Nup153. On n...

Gleason grading is now the most widely used grading system for prostatic carcinoma in the United States. However, there are only a few studies of the interobserver reproducibility of this system, and no extensive study of interobserver reproducibility among a large number of experienced urologic pathologists exists. Forty-six needle biopsies containing prostatic carcinoma were assigned Gleason ...

Attracting shoppers to stores and converting the incoming traffic into sales profitably are vital for the financial health of retailers. In this paper, we use proprietary data pertaining to an apparel retailer to study the relationship between store traffic, labor, and sales performance. We decompose sales volume into conversion rate (defined as the ratio of number of transactions to traffic) a...

The paper updates the answer to the question: what precisely is the exchange rate regime that China has put into place since 2005, when it announced a move away from the dollar peg? Is it a basket anchor with the possibility of cumulatable daily appreciations, as was announced at the time? We apply to this question a new approach to estimating countries’ de facto exchange rate regimes, a synthe...

Complex endourologic procedures may require the use of a combined ureteroscopic and percutaneous approach. Endoscopic removal of a retained 4-wire ureteral stone basket is particularly complex, as broken tines can potentially injure the ureter if the basket is removed in a retrograde manner. The patient in this case presented with a ureteral stone basket embedded within the urothelium of the up...
