Eligibility Criteria:
Inclusion Criteria:~* Cases:~  * male or female patients aged between 21 and 65 years with typical clinical manifestations of gastroesophageal reflux but endoscopy-negative for esophageal mucosal breaks~ * by typical clinical manifestations of gastroesophageal reflux, we refer to the occurrence of heartburn and/or regurgitation more than twice a week, with a minimum duration of 8 consecutive weeks, and with symptoms severe enough to affect daily activities~* Controls:~  * healthy male or female aged between 21 and 65 years who are asymptomatic for GERD and other digestive diseases~Exclusion Criteria:~* Endoscopic confirmed erosive esophagitis~* Complications such as Barrett's esophagus, gastric and/or duodenal peptic ulcer, stenosis~* Esophageal, gastric or duodenal cancer or other malignancy~* History of esophagus, stomach, or duodenum surgery~* Conditions that preclude safe biopsies (coagulopathy, haemophilia, esophageal varices, and patients on warfarin and antiplatelets)~* Scleroderma, diabetes mellitus, autonomic or peripheral neuropathy, myopathy or any underlying disease or medication that might affect the lower esophageal sphincter pressure or increase the acid clearance time~* A history of bronchial asthma, or known allergy to fluorescein~* Pregnant or breast-feeding (for females)~* Below 21 or above 65 years of age~* Severe co-morbidities (e.g., such as end-stage renal failure, congestive cardiac failure, liver cirrhosis, severe arthritis requiring long term non-steroidal anti-inflammatory drug therapy)~* Unable or unwilling to give informed consent

- Gender: ALL
- Minimum Age: 21 Years
- Maximum Age: 65 Years
- Healthy Volunteers: t

Study Arms:
- Case (subjects with NERD) (Type: None): The investigators cases are subjects with confirmed NERD and include male or female patients aged between 21 and 65 years, who present with typical clinical manifestations of gastroesophageal reflux and have no esophageal mucosal breaks upon conventional white-light endoscopy examination but show evidence of pathologic gastroesophageal reflux on 24-hr pH monitoring.
- Control (Type: None): Healthy individuals aged between 21 and 65 years who are asymptomatic for GERD and other digestive diseases
