Cell Marker Predictors in Barrett's Esophagus

The purpose of this study is to analyze biopsied tissue samples for changes in cells and genes involved in Barrett's Esophagus.

Familial 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...

Acid Reflux and Stromal Fibroblasts in Barrett's Esophagus

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 ...

Minimally-Invasive Detection of Barrett's Esophagus and Barrett's Esophagus Related Dysplasia/Carcinoma

This study will evaluate if the capsule sponge device can detect the presence of Barrett's Esophagus

DNA Changes as a Risk Factor for Barrett's Esophagus in Patients With Barrett's Esophagus, Gastroesophageal Reflux, or Gastrointestinal Bleeding

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...

Treatment Outcomes of Endoscopic Submucosal Dissection for Adenocarcinoma Originating from Long-Segment Barrett's Esophagus versus Short-Segment Barrett's Esophagus.

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,...

Some observations on Barrett esophagus and associated dysplasia.

Biopsy samples from esophageal columnar metaplasia and dysplasia are commonly encountered in Western pathology practice and knowing a few pitfalls can save both pathologists and patients a great deal ...

Microsatellite instability in metaplasia-dysplasia-adenocarcinoma sequence of Barrett esophagus: a retrospective study.

To analyze the loss of mismatch repair (MMR) system protein expression in metaplasia-dysplasia-adenocarcinoma sequence of Barrett esophagus (BE).

Multifocal nitrous oxide cryoballoon ablation with or without EMR for treatment of neoplastic Barrett's esophagus.

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...

Association of Vitamin D and Parathyroid Hormone With Barrett's Esophagus.

Esophageal adenocarcinoma has been inversely associated with exposure to ultraviolet radiation. This could be because of vitamin D deficiency or hyperparathyroidism promoting gastroesophageal reflux d...

Medical and Biotech [MESH] Definitions

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.
