Disease relevance of Diverticulum

  • Targeted projections, made up of a limited number of coronal source images, showed diverticula and smaller polyps more clearly [1].
  • In 11 patients abnormalities were diagnosed on the basis of iohexol esophagograms; the abnormalities included extraluminal extravasation of contrast material (n = 7), aspiration (n = 1), esophageal stricture with intramural diverticulosis (n = 1), edema of the gastroesophageal junction (n = 1), and epiphrenic diverticulum (n = 1) [2].
  • Serum samples from 84 benign colorectal disease cases were examined; of these, 0 of 28 (0%) colorectal adenoma, 1 of 39 (3%) ulcerative proctocolitis, 0 of 15 (0%) diverticulosis, and 0 of 2 (0%) irritable bowel disease sera contained more than 10 mu/ml CA 72 [3].
  • In conclusion patients with spinal meningeal diverticula (frequently seen in Marfan's syndrome) might be at increased risk of developing CSF leaks, possibly secondary to Valsalva maneuver or minor unrecognized trauma [4].
  • This article describes the clinical and morphologic features of this unusual case, reviews the topic of neoplasms involving hernia sacs and Meckel's diverticula, and includes a brief review of immunocytochemical findings in carcinoid tumors [5].

Chemical compound and disease context of Diverticulum

 

Biological context of Diverticulum

  • This line, HBC-3, stains positively for alpha-fetoprotein, albumin, and cytokeratin 14 (CK-14), protein markers expressed by the embryonic liver diverticulum, indicating that HBC-3 cells retain an undifferentiated hepatoblast phenotype [17].
  • Reporter gene expression analyses also revealed several previously unknown sites of Nkx3.1 expression in males, including urethral glands, glandular cells in the urethral diverticulum and basal epithelial cells in the prostate [18].
  • STUDY DESIGN/MATERIAL AND METHODS: Between 1976 and 1993, 109 patients with a hypopharyngeal diverticulum were operated on at the Department of Otorhinolaryngology, Head and Neck Surgery, University of Kiel, either transcutaneously combined with a cricopharyngeal myotomy (n = 76), or microendoscopically (n = 37) using the CO2 laser [19].
  • Digestive cells ensure intracellular digestion of nutrients absorbed by pinocytosis and store glycogen, lipids and mineral salts; the wastes of the digestive process (guanine, uric acid, mineral elements, pigments) are concentrated in "brown body vacuoles" which are ejected into the lumen of the diverticula [20].
  • A disappearance of apoptotic cells was associated with strong Bcl-2 expression in the foregut diverticulum at 10.5 and 11.5 days of gestation [21].
 

Anatomical context of Diverticulum

 

Gene context of Diverticulum

  • In situ hybridization studies of staged specific embryos demonstrate that HNF-6 and its potential target gene, HNF-3 beta, are coexpressed in the pancreatic and hepatic diverticulum [27].
  • T/ebp/Nkx2.1 haploinsufficiency causes abnormal fusion of the UBB with the thyroid diverticulum, which stays as a cluster of C-cells around the vesicular structure, similar to the one observed in mice null for T/ebp/Nkx2.1 expression [24].
  • In particular, in the region of the foregut that gives rise to the liver, Hex expression is nuclear in the endodermal cells of the hepatic diverticulum, whereas expression is primarily cytoplasmic in cells lateral to the liver-forming region [28].
  • In humans, AFP is expressed in the hepatic diverticulum at 26 d postovulation as it differentiates from the foregut endoderm (i.e. in the most primitive hepatocytes) [29].
  • Right atrial diverticulum and hypertrophic cardiomyopathy [30].
