Progressive Endoscopic Approach To Balloon Dilation For Benign Esophageal Strictures, Chad J. Cooper
Progressive Endoscopic Approach To Balloon Dilation For Benign Esophageal Strictures, Chad J. Cooper
Theses and Dissertations--Clinical and Translational Science
Benign esophageal strictures are a frequently encountered problem in clinical practice. The management of benign esophageal strictures have slowly evolved over the decades based on “expert opinion.” Despite vast amounts of data about the efficacy and safety of dilation, unfortunately there is no consensus on a systematic and safe approach that is efficient, limits complications and provides long lasting improvement of dysphagia. Our group designed a progressive approach to endoscopic balloon dilation based on tailoring certain technical aspects of the dilation process.
Most studies in the literature concluded that endoscopic dilation is safe and effective in relieving dysphagia caused by …

Elucidating The Complex Signaling Events Driving Intestinal Stem Cell Plasticity Following Injury, Evan Lynch
Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics
Signaling events governing intestinal stem cell (ISC) homeostasis maintain the delicate balance of active self-renewal and passive differentiation to replenish intestinal epithelial cells (IEC) every 3-5 days. However, under certain contexts, ISC function is irreversibly compromised—requiring committed IEC lineages to dedifferentiate and regain “stemness”. In the current studies, we examine the signaling events driving epithelial cell responses to injury to expose pathologic failures in the healing response. Our specific goal is to tease out the cellular contexts that promote dedifferentiation to design effective therapeutics for disease conditions compromising ISC function.
First, we generated a novel transgenic animal using the epithelial-specific …
