PURPOSE The aim of this study was to compare survival in patients that underwent palliative resection treatment versus non-resection for incurable colorectal cancer (ICRC). METHODS The case records of 201 patients with ICRC between January 2000 and December 2009 were reviewed. Demographics, American Society of Anesthesiologists (ASA) score, carcinoembryonic antigen (CEA) level, the location o...

We propose a method to derive the low-energy efective action of QCD assuming that the long-distance properties of strong interactions can be described by a string theory. We bypass the usual problems related to the existence of the tachyon and absence of the adequate Adler zero by using a sigma model approach where excitations above the correct (chirally non-invariant) QCD vacuum are included. ...

Arteriocolic fistula is a rare but life-threatening condition. We report the case of a 70-year-old man who presented with passage of bloody stools and intolerable abdominal pain. Esophagogastroduodenoscopy and colonoscopy failed to identify the source of the bleeding. Contrast-enhanced abdominal computed tomographic scans showed an aneurysm arising from the left common iliac artery with close a...

background: colorectal cancer is a common and lethal disease with various distribution of incidence in different part of the world and it is known as the third most common cause of cancer death in the world. since several studies in the world represented different survival rates for colorectal cancer in this study we aimed to determine the survival of a group of iranian patients and some relate...

background colorectal cancer (crc) is one of the most common cancers worldwide which is not extensively researched in iran. objectives the present study aims to investigate the epidemiologic characteristics of crc in patients referred to selected hospitals of tehran university of medical sciences. patients and methods in this descriptive-analytic study 218 patients with colorectal cancer were i...

Abstract Roux-en-Y gastric bypass (RYGB) has been demonstrated to be the most effective treatment for morbid obesity, yet impact of RYGB on intestinal permeability is not fully known. In this work, we subjected obese mice and sham operation procedures. Serum lipopolysaccharide (LPS) level, inflammatory cytokines were measured at 8 weeks post surgery. contrast surgery, reduced body weight, impro...
