Summary
The symptoms of gastroesophageal reflux (heartburn and acid burning) are extremely common in individuals with obstructive sleep apnoea (OSA), especially during sleep (nocturnal reflux). The reasons for this are unclear. This research project will investigate the reasons for this increased occurrence of reflux in OSA.

Summary
Some people with severe reflux develop Barrett's oesophagus, which puts them at high risk of developing cancer. Patients with Barrett's can be treated with various endoscopic ablation techniques, but it is not yet know if these treatments prevent the development of cancer. The aims of this work are to use molecular methods to ascertain whether the tissue that regenerates after ablation is normal, and to compare different ablation techniques.

Summary
17% of Australians use medication for gastro-oesophageal reflux, with many requiring tablets life long. In >15% this is not adequate. The alternative is surgery which is the only curative treatment for reflux and hiatus hernia. It achieves a good outcome in 90%, although some develop further reflux or side effects. To reduce problems procedures have been modified. In a series of trials we are evaluating long term outcomes for modifications, to determine the best surgical treatment for reflux.
Regulated Intracellular Trafficking Of A Potassium Channel In Gastric Acid-secreting Cells

Summary
The cells of our bodies possess proteins that transport salts and other chemicals. These transport proteins must be correctly positioned in cells, a process that is poorly understood. If transport proteins are not positioned properly then diseases such as heart attack or diabetes may occur. Influencing the position of transport proteins may also be used to treat disease. This work investigates how a transport protein that shuttles potassium is correctly positioned in cells of the stomach.
