By using the gauge Ward identities, we study correlation functions of gauged WZNW models. We show that the gauge dressing of the correlation functions can be taken into account as a solution of the Knizhnik-Zamolodchikov equation. Our method is analogous to the analysis of the gravitational dressing of 2D field theories.

aim : the aim of this study was to compare prognostic factors between colon and rectal cancers. background : prognosis of colorectal cancer (crc) may depend on the anatomical site. patients and methods : a total of 1219 patients with crc diagnosis according to the pathology report of rcgld cancer registry, from 1 january 2002 to 1 october 2007, were entered into the study. demographic and clini...

bowel stent insertion has a variety of complications one major of which is colonic perforation. the purpose of this article is to reveal two cases with delayed colonic perforation after stent placement to relieve bowel obstruction caused by rectal cancer. the first patient was a 55 year-old man who was a candidate for stent placement to avoid palliative surgery and relieve his bowel obstruction...

In order to relieve mechanical obstruction caused by rectal carcinoma, a bare rectal stent was inserted in the sigmoid colon of a 70-year-old female. The procedure was successful, and for one month the patient made good progress. She then complained of abdominal pain, however, and plain radiographs of the chest and abdomen revealed the presence of free gas in the subdiaphragmatic area. Surgical...

These lecture notes are devoted to the theory of “equations of associativity” describing geometry of moduli spaces of 2D topological field theories.

Introduction: The close proximity of the rectum tissue to the prostate gland results in rectal toxicity during prostate radiotherapy. Rectal Retractor (RR) is a rectal displacement technique that inserts into the rectum, as a result, the lateral and dorsal part of the rectal wall push away from high dose areas. The aim of this study was to investigate the dosimetric consequence...

the effect of intracerebroventricular injections of prostaglandins e2 and f2a was studied on the rectal temperature of sheep. pge2 but not pgf2a at the same dose of 50mg elevated the 1h post-injection of rectal temperature. pge2 but not pgf2a at the same dose of 100mg increased 3.5 and 2h post-injection of rectal temperature, respectively. elavation of rectal temperature following pge2 and pgf2...
