Ulcerative colitis (UC) classification, which is an important task for endoscopic diagnosis, involves two main difficulties. First, images with the annotation about UC (positive or negative) are usually limited. Second, they show a large variability in their appearance due to location colon. Especially, second difficulty prevents us from using existing semi-supervised learning techniques, commo...

The ingestion of foreign bodies is a common cause for presentation in the emergency department by pediatric, adult, or elderly psychiatric patients. Swallowed sometimes represent great challenge surgeons due to obstruction perforation digestive tube’s upper lower segments. Occasionally, detected parts tube (colon and rectum) could be introduced through anal route with risk rectum sigmoid colon....

Objective: This study analyzes the influence of sex, age and body mass index on anatomy colon as determined by three-dimensional reconstructions from computed tomography scans. Methods: 130 patients were included, each whom underwent a reconstruction abdominal CT scans without obvious signs pathology. Information corresponding to was obtained patient, morphometric data measurements taken at pub...

La diverticulosis cólica se define por una anomalía anatómica adquirida del colon, que caracteriza la presencia de seudodivertículos formados herniaciones mucosa y submucosa a través capa muscular colon. Es las patologías más comunes nivel intestino grueso en el mundo occidental su prevalencia durante último siglo ha incrementado probablemente debido cambios los estilos vida. enfermedad diverti...

We consider the identity component of Sato-Tate group Jacobian curves form $$C_1\colon y^2=x^{2g+2}+c, C_2\colon y^2=x^{2g+1}+cx, C_3\colon y^2=x^{2g+1} +c,$$ where $g$ is genus curve and $c\in\mathbb Q^*$ constant. approach this problem in three ways. First we use a theorem Kani-Rosen to determine splitting Jacobians for $C_1$ 4 5 prove what each case. then higher by finding maps lower computi...

aim : the aim of this study was to report the anatomical location and histologic type of colorectal polyps in a large series of iranian patients that attended for colonoscopy. background : polyps that develop through the adenoma-carcinoma pathway are considered neoplastic and may eventually progress to invasive carcinomas. in addition polyps can develop with no neoplastic potential. these neopl...

Nanomedicines In article 2201140 by Hsin-Cheng Chiu and co-workers, an oral polysaccharide microgel formulation containing dual-modality therapeutic nanoparticles developed for local treatment of colon cancer is imparted to hierarchical targeting residues, leading increases in retention cell uptake nanotherapeutics. With enzymatic degradation dextran microgels occurring exclusively the colon, n...

background: in iran colorectal cancer (crc) incidence varies among various places. but we do not have any validate data that deeply explored the difference of crc in kerman province by national average. the aim of this study was to evaluate the incidence of colon cancer within a 12-year period in kerman province and to find whether the incidence of crc in kerman compared with the total incidenc...

incidence of cancer increases exponentially with age. Aging may lead to pathologies due to the physiologic decline or aberrancy in the functions of adult stem cells, whose intrinsic capacity for self-renewal helps maintain tissue homeostasis. The majority of cancers arise from replication-induced somatic mutations in adult stem cells [1], which predisposes to hijacking their self-renewal pathwa...

Tumor sidedness has emerged as an important prognostic and predictive factor in the treatment of colorectal cancer. Recent studies demonstrate that patients with advanced right-sided colon cancers have a worse prognosis than those with left-sided colon or rectal cancers, and these patient subgroups respond differently to biological therapies. Historically, management of patients with metastatic...
