Identification of novel gastric stem cell markers and investigation of Intestinal Stem Cell Cre-mediated Recombination
<p>Very few genetic markers for gastric stem cells are currently described. Identifying new markers is important for increasing our basic understanding of gastric tissues and studying mechanisms of cancer development. Gastric and intestinal tissues share a common developmental program. Thus, …

Epidermal growth factor receptor in equine gastric stratified squamous mucosa: effect of progressive ulceration on receptor density
… density in normal as well as ulcerated equine gastric squamous mucosa. Fifteen horses with endoscopically normal stomachs were divided into three equal groups. Group 1 was a normal control. A protocol that alternated 24 hour periods of free-choice hay with 24 hours of feed deprivation was …

A detailed design analysis of a lumenally delivered, flexible, balloon-assisted, sterile endoscopic overtube.
… research for this thesis focused primarily on gastric interventions is divided into four main foci: tensile testing and determination of the most accurate material model for human gastric tissue, FEA analysis of the balloon dilation, experimentally validating these results using a silicone …

The isolation, purification, tissue localization and identification of a glycoprotein found in the crude mucus gel of patients with carcinoma of the stomach
The thin layer of crude mucus lining the human gastric mucosa protects the delicate gastric epithelium from the high shear forces associated with digestion. Gastric mucus is composed largely of water (>90%) and a complex mixture of organic components such as enzymes, various serum and cellular …

Identification and Characterization of the Helicobacter Pylori Vacuolating Cytotoxin Receptor
Chronic infection with the gastric pathogen Helicobacter pylori is a risk factor for the development of gastric ulcer disease or gastric adenocarcinoma in humans. The success of H. pylori in the harsh stomach environment is due largely to pathogen-mediated remodeling of gastric tissue by virulence …

The Recruitment and Function of Tumor Microenvironment Components During Gastric Carcinogenesis
… used for numerous years as a standard model of gastric carcinogenesis and recapitulates the pathogenesis seen with human Helicobacter pylori infection. H. felis induces a a wide array of chronic low grade inflammatory responses, some of which directly contribute to carcinogenesis and some of …

Biochemistry in healthy and neoplastic human tissues: metabolic alteration revealed by HR-MAS nuclear magnetic resonance spectroscopy
… focused on the metabolomic study of human cancer tissues by ex vivo High Resolution-Magic Angle Spinning (HR-MAS) nuclear magnetic resonance (NMR) spectroscopy. This new technique allows for the acquisition of spectra directly on intact tissues (biopsy or surgery), and it has become very important …
