a new species of cassiduloid echinoids, pygaulus baghinensis is reported for the first time from aptian sediments of baghin area, west of kerman, iran. the diagnostic features of the species are centrally positioned of the apical disc and approximately low profile of the test. variation in gonopore size in different individuals allows to conclude that p. baghinensis is sexually dimorphic. speci...

Endoscopic submucosal dissection (ESD) was performed for early rectal cancer in a 70-year-old man (●" Fig.1). The bulky tumor occupied nearly half of the lumen. As the forcible removal of the resected specimen from the rectum using only the retrieval net (Disposable Loop Retrieval Net; net diameter 40×75 mm; Meditalia, Palermo, Italy) could have resulted in its fragmentation, we decided to take...

introduction: renal length measurement is an important diagnostic clue in several urinary tract abnormalities. although ultra sonography is the most frequent used modality for renal size estimation, renal diameter assessment by 99mtc-dmsa scintigraphy is of great value. by now, pointing to the renal size in the 99mtc-dmsa scintigraphy report has not been recommended by guidelines. if the validi...

The present paper investigates the influence of specimen size EN-AW6082 wrought aluminium alloy subjected to very high cycle fatigue (VHCF) tests. hourglass specimens were tested under fully reversed loading condition, up 109 cycles, by means ultrasonic testing machine developed Italsigma® (Italy). Three groups considered, with a diameter in middle cross-section ranging from 3 mm 12 mm. stress ...

PURPOSE To evaluate the accuracy of radiologic tumor size for making decisions regarding nephron-sparing surgery of localized renal cell carcinomas (RCCs), we compared tumor size measured by a preoperative radiologic modality with that measured in the pathologic specimen. MATERIALS AND METHODS Between January 2003 and December 2007, a total of 186 patients with pT1 or pT2 RCC underwent radica...

Small samples of rock, like those used in laboratory collision experiments, are known to be much stronger than bodies that are meters to hundreds of meters in size [1]. Specifically, the impactor energy per unit target mass needed to shatter the target decreases dramatically with increasing target size. This occurs because the strength of rock, like many other geological materials, depends stro...

BACKGROUND Gastric endoscopic submucosal dissection (ESD) has gradually come to be recommended as the optimal treatment for early gastric cancer; however, one of the primary issues is postoperative bleeding. Although second-look endoscopy is conventionally performed to reduce the risk of postoperative bleeding, its benefit has not yet been clearly elucidated. The objective of this study was to ...
