Although peroxisome proliferator-activated receptor γ (PPARγ) is strongly expressed in the intestinal epithelium, the role of PPARγ in intestinal tumorigenesis has not yet been elucidated. To address this issue, we investigated the effect of PPARγ inhibition and its mechanism on intestinal tumorigenesis using a selective antagonist, T0070907. We treated Apc /+ mice and carcinogen-induced colon ...
Neonatal mice with cystic fibrosis (CF) exhibit a very high mortality due to intestinal obstruction localized primarily to the ileum and colon. It has been hypothesized that lack of Cl- secretion and possibly elevated Na+ absorption contribute to the gut problems in CF neonates. Therefore, intestines (ileum, proximal colon, and distal colon) from normal and CF day-old mouse pups were studied on...
Peroxisome proliferator-activated receptor gamma (PPARgamma), a fatty acid-activated nuclear receptor, is implicated in adipocyte differentiation and insulin sensitisation. In view of the association of dietary fat intake and bowel disease, the expression of PPARgamma in rodent and human intestine was studied. Expression of PPARgamma mRNA was examined by Northern blot hybridisation, RNase prote...
The effects of Yersinia enterocolitica on intestinal goblet cells were investigated in New Zealand white rabbits. Animals infected with Y enterocolitica were compared with weight matched and pair fed controls. Goblet cell hyperplasia developed in the distal small intestine of infected rabbits on day 1, in the mid small intestine on day 3, and in the upper small intestine on day 6. In all region...
Progress toward the understanding and management of human colon cancer can be significantly advanced if appropriate experimental platforms become available. We have investigated whether a rat model carrying a knockout allele in the gatekeeper gene Adenomatous polyposis coli (Apc) recapitulates familial colon cancer of the human more closely than existing murine models. We have established a mut...
BACKGROUND Despite the growing acceptance of laparoscopic colon surgery, an abdominal incision is needed to remove the specimen and perform an anastomosis. Recently, natural orifice specimen extraction (NOSE) and intracorporeal anastomosis have been proposed to minimize abdominal wall trauma and improve the quality of laparoscopic colon resections Objective: To evaluate the feasibility and safe...
background and aims: among all cancers, colon cancer is common and deadly, yet preventable. the estimated worldwide incidence of colon cancer is more than one million new cases per year. this study was done to identify the epidemiological features and risk factors of colon cancer in different regions of birjand. methods: this retrospective, descriptive analytical study of patients with colon ca...
In patients with ulcerative colitis a colon tissue bound IgG and serum antibodies against an Mr 40,000 colonic protein(s) has been identified. Using an anti-Mr 40,000 protein monoclonal antibody, 7E12H12, by an immunocytochemical method, the protein was localised in human tissue exclusively to colonic epithelial cells. In this study the presence of the Mr 40,000 protein was assessed in experime...
colorectal cancer (crc) metastasis to the thyroid gland is rare. here wereport a 45 yr-old man in western iran referred to hematology clinic, kermanshah city, iran in march 2014 with complaint of exertional dyspnea, multi-nodular goiter as well as complaint of exertional dyspnea, and multi-nodular goiter. his history included a low anterior resection of rectum in 9 months ago for a high-risk st...
Volvulus is a common surgical emergency and in most of the cases requires prompt diagnosis and treatment in order to evolve favorably. We present you a case of a 6year-old male with a massive volvulus involving a large portion of small bowel and sigma that did not evolve favorable. There are no prospective, randomized studies comparing treatment options and the most frequently raised questions ...
