A Submucosal Lipoma of Small Intestine as an Unpredictable Cause of Intussusception and Intestinal Obstruction; A Case Report and Literature Review

Asian Pacific Journal of Cancer Biology, 2022
Background: Intussusception refers to telescoping of one intestinal segment and its mesentery into an adjacent intestinal loop. It is a rather frequent entity in infants with an excellent prognosis.

PRAPNet: A Parallel Residual Atrous Pyramid Network for Polyp Segmentation

Sensors, 2022
In a colonoscopy, accurate computer-aided polyp detection and segmentation can help endoscopists to remove abnormal tissue. This reduces the chance of polyps developing into cancer, which is of great importance. In this paper, we propose a neural network

Stat6 Promotes Intestinal Tumorigenesis in a Mouse Model of Adenomatous Polyposis by Expansion of MDSCs and Inhibition of Cytotoxic CD8 Response

Neoplasia: An International Journal for Oncology Research, 2017
Intestinal tumorigenesis in the ApcMin/+ model is initiated by aberrant activation of Wnt pathway. Increased IL-4 expression in human colorectal cancer tissue and growth of colon cancer cell lines implied that IL-4–induced Stat6-mediated tumorigenic ...
