Development of Multi-Modality Imaging Cart for Barrett’s Esophagus
Barrett’s Esophagus (BE) is a key precursor to esophageal adenocarcinoma (EAC), but current screening and risk assessment methods are ineffective and costly. Many BE cases remain undiagnosed due to asymptomatic patients, and existing risk algorithms rely on patient data rather than biomarkers. This …

Development of a real time trimodal spectroscopy diagnostic tool for Barrett's esophagus
Barrett's esophagus (BE) is a condition of the lower esophagus caused by gastroesophageal reflux disease. Patients with BE have an increased probability of developing dysplasia, an abnormal growth or development of cells. This dysplasia in BE is a precursor to cancer of the esophagus, but is …

The Pathophysiology of Eosinophilic Esophagitis: Altered Mechanisms of Antigen Detection in the Esophagus
Recently, a chronic idiopathic disease of the esophagus has emerged, which is now known as eosinophilic esophagitis (EoE). Incomplete knowledge regarding the pathogenesis of EoE has limited treatment options. EoE is known to be a Th2-type immune-mediated disorder. Based on previous studies in both …

Investigation of Radiation Injury In The Esophagus From Definitive Chemoradiation Therapy Using Novel Imaging Biomarkers
<p>Radiation injury in the esophagus occurs with high frequency from the treatment of non-small cell lung cancer (NSCLC). Radiation esophagitis is an acute normal tissue toxicity that negatively affects treatment efficacy by limiting dose and potentially interrupting radiation therapy. Clinical …

Detection of Symptomatic Heterotopic Gastric Mucosa of the Upper Esophagus using Tc-99m Pertechnetate Scintigraphy
… Heterotopic Gastric Mucosa of the Upper Esophagus using Tc-99m Pertechnetate Scintigraphy Heterotopic gastric mucosa of the upper esophagus (HGMUE) often referred to as an inlet patch, is an asymptomatic benign lesion. However, this inlet patch may cause esophageal ulceration and …

The Columnar Lined Esophagus: aspects on the assessment of dysplasia and on the relationship with the esophageal submucosal glands
… replaces the normal squamous epithelium in esophagus, is considered to be a precancerous condition in which the development of adenocarcinoma can be followed through various grades of dysplasia. The interpretation of these histological changes is subjective and suffers from considerable …

Factors influencing on esophageal baseline impedance levels in patients with suspected symptoms of gastroesophageal reflux disease
… Baseline impedance was measured in the proximal esophagus (the average of 15 and 17 cm) and the distal esophagus (the average of 3 and 5 cm) at 5 min before meal, 5 min after the meal period, 30 min after the meal period, 30 min before sleep, 30 min after sleep onset and 60 min after sleep onset. …

Penetration of Carcinogen Across Porcine Esophagus and Applications of Disposable Pipette Extraction for Forensic Toxicology and Food Safety by Gas and Liquid Chromatography/Mass Spectrometry
<p>This dissertation focuses on the chemical analyses of N-nitrosonornicotine from (NNN) porcine esophageal tissue, benzodiazepines (BZDs) and steroids in urine, and toxins such as melamine and pesticides in various foods. The effects of menthol, ethanol and also acetaldehyde on the flux of NNN …
