Summary
We don't understand what happens during a non-epileptic seizure. Patients can't tell us and we can't use normal brain scanning during a seizure as the patient moves too much. Our idea is to take patients with non-epileptic seizures on the epilepsy wards who are being monitored and inject them with a radioactive tracer as soon as the seizure starts, then we can scan them afterwards to see what parts of their brain were active during the seizure, so we will understand what was happening.

Summary
After a heart attack, up to 50% of tissue showing reduced function can recover if blood supply is returned to normal with bypass surgery or balloon angioplasty. Because these procedures may be risky in cardiac patients, the investigators have used various imaging approaches including radionuclide and ultrasound techniques to predict regions where function will recover after intervention. The results of these tests may be discordant because they assess separate attributes of cardiac muscle, and s ....After a heart attack, up to 50% of tissue showing reduced function can recover if blood supply is returned to normal with bypass surgery or balloon angioplasty. Because these procedures may be risky in cardiac patients, the investigators have used various imaging approaches including radionuclide and ultrasound techniques to predict regions where function will recover after intervention. The results of these tests may be discordant because they assess separate attributes of cardiac muscle, and selection of patients for intervention on the basis of recovery of regional function ignores some other aspects that may be important. These include avoidance of heart enlargement, improvement of exercise capacity, and avoidance of heart rhythm disturbances and even other heart attacks. In this study, the investigators seek to define the importance of the proportion and site of live (viable) myocardium to the parameters listed above. A new magnetic resonance technique will be used to identify whether radionuclide and ultrasound techniques assess different parts of the heart wall. The relative importance of these sites will be identified by comparing the outcome of patients who have live tissue in the inner half, compared with the outer half of the heart wall. This study will involve 180 patients who will undergo testing with magnetic resonance and radionuclide imaging. A subgroup will undergo dobutamine echocardiography. Their responses over follow-up will be assessed by accurate evaluation of heart size, exercise response, heart rhythm abnormalities and clinical events.Read moreRead less

Summary
Melanoma is a form of skin cancer that arises from the cells that produce pigment and is a major public health issue in Australia. We will examine the relationship between the form, structure and colour of existing types of moles and their subsequent risk of developing into melanoma. This study will combine dermoscopy, a non-invasive examination technique, with DNA tests of the genes that determine number of naevi, skin, hair and eye colour, aiding in the early prediction and diagnosis of skin c ....Melanoma is a form of skin cancer that arises from the cells that produce pigment and is a major public health issue in Australia.

Summary
This project will focus on finding genes for common human diseases. Now that the human genome has been sequenced, the race is on to find out what the estimated 38,000 human genes do and which ones are associated with which diseases. Scattered throughout the genome are small variations in DNA sequence, some of which increase the odds of disease while others are protective.
I am a clinician-scientist and endocrinologist most interested in clinical problems associated with bone, in particular the highly heritable disease of osteoporosis. I hope by studying genetic determinants of bone mass to determine the key genes involved, with the long term aim of informing the development of novel therapies for this common, painful and disabling disease.
