The purpose of this study is to analyze biopsied tissue samples for changes in cells and genes involved in Barrett's Esophagus.
This is a multi-center study whose aim is to define the epidemiology and genetics of Barrett's esophagus and adenocarcinoma. The researchers have studied families affected with Barrett's e...
Patients with Barrett's Esophagus are known to have excessive distal esophageal acid exposure comparable to patients with erosive esophagitis. A significant proportion of patients with BE ...
This study will evaluate if the capsule sponge device can detect the presence of Barrett's Esophagus
RATIONALE: A study that evaluates DNA changes and other disease-related health information in patients with Barrett's esophagus, gastroesophageal reflux, or gastrointestinal bleeding may h...
In recent years, effective outcomes of endoscopic submucosal dissection (ESD) for esophagogastric junction cancer including short-segment Barrett's esophagus (SSBE) cancer have been reported. However,...
Endoscopic cryotherapy can eradicate neoplastic Barrett's esophagus (BE). A new contact cryoballoon focal ablation system (CbFAS)) freezes esophageal mucosa with nitrous oxide. We studied the safety a...
To identify risk factors associated with Barrett esophagus (BE) for potential improved surveillance and risk reduction.
PURPOSE OF REVIEW: There is a pressing need for effective strategies to halt the increase in both the incidence and mortality of esophageal adenocarcinoma (EAC). Screening for Barrett's esophagus, whi...
Barrett's esophagus progresses to esophageal adenocarcinoma in a stepwise histological fashion of no dysplasia, low grade dysplasia, high grade dysplasia and cancer. Hence the progression to cancer fr...
A condition with damage to the lining of the lower ESOPHAGUS resulting from chronic acid reflux (ESOPHAGITIS, REFLUX). Through the process of metaplasia, the squamous cells are replaced by a columnar epithelium with cells resembling those of the INTESTINE or the salmon-pink mucosa of the STOMACH. Barrett's columnar epithelium is a marker for severe reflux and precursor to ADENOCARCINOMA of the esophagus.
Methods of implanting a CELL NUCLEUS from a donor cell into an enucleated acceptor cell. Often the nucleus of a somatic cell is transferred into a recipient OVUM or stem cell (STEM CELLS) with the nucleus removed. This technology may provide means to generate autologous diploid pluripotent cell for therapeutic cloning, and a model for studying NUCLEAR REPROGRAMMING in embryonic stem cells. Nuclear transfer was first accomplished with frog eggs (RANA PIPIENS) and reported in 1952.
The release of stem cells from the bone marrow into the peripheral blood circulation for the purpose of leukapheresis, prior to stem cell transplantation. Hematopoietic growth factors or chemotherapeutic agents often are used to stimulate the mobilization.
The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
A protein-tyrosine kinase receptor that is specific for STEM CELL FACTOR. This interaction is crucial for the development of hematopoietic, gonadal, and pigment stem cells. Genetic mutations that disrupt the expression of PROTO-ONCOGENE PROTEINS C-KIT are associated with PIEBALDISM, while overexpression or constitutive activation of the c-kit protein-tyrosine kinase is associated with tumorigenesis.
