hiatus. The lower esophageal sphincter is maintained in tension at all times, except in response to a descending contraction wave, at which point it relaxes momentarily to allow the release of gas (belching) orvomiting. The lower esophageal sphincter has an important role, therefore, in ...
24) [3]. Double contrast esophagography may play a vital role in stratifying patient risk. If the hallmark features of mid-esophageal stricture with distal esophageal reticular mucosal pattern are present on esophagography, the patient is likely to have Barrett’s esophagus and will benefit from ...
Lingual glands in the lamina propria of the tongue secrete mucus and a watery serous fluid that contains the enzyme lingual lipase, which plays a minor role in breaking down triglycerides but does not begin working until it is activated in the stomach. A fold of mucous membrane on the ...
In support of a role for reprogramming of progenitor cells by GERD in the development of BE, telomerase-immortalized human esophageal squamous cells exposed in vitro to acid, bile salts, or nitric oxide (a toxic molecule formed when dietary nitrate encounters acid in refluxed gastric juice) down...
28 The ganglia of the myenteric plexus are more numerous in the smooth muscled esophagus than in the striated muscle esophagus.29 In the smooth muscled esophagus, the neurons of the myenteric plexus are relay neurons between the vagus and the smooth muscle. In the striated muscle the role of ...

(Fig.1a, b, Supplementary Fig.1a, Supplementary Data1, Methods). For 15 of the donors, we obtained and separately analyzed biopsies from both proximal and distal regions of the esophagus (Fig.1a, b, Supplementary Fig.1a). Each biopsy was processed individually with a rapid digestion protocol...

Objectives Recent studies indicate that colonization with cagA-positive Helicobacter pylori (H. pylori) strains may protect against gastroesophageal reflux disease (GERD) and its complications, but the role of cagA in the etiology of Barrett’s esophagus has so far been poorly investigated. The ...
