Molecular Imaging Of Brain Tumour Therapeutic Efficacy

Summary
The prognosis for malignant brain tumour patients that do not respond to intial treatment strategies is very poor. The fact that many of these patients patients will not survive longer than 12 months post diagnosis underscores the need to make treatment management decisions in a timely manner. This project seeks to develop and validate non-invasive early molecular imaging biomarkers that can quantify treatment efficacy months before traditional measures of efficacy are valid.
What Contributes To Regional Vulnerability In Neurodegenerative Diseases? A Study Of Familial Cases.

Summary
Unfortunately, as many people live longer, more and more are afflicted by degenerative changes that affect their brain. These neurodegenerative diseases are usually relentlessly progressive and with time render patients incapable of many normal functions. For some families with certain genetic defects, these diseases occur aggressively and early. We would like to study the brains of patients from these families because in most cases the proteins affected by the gene defect have been identified. ....Unfortunately, as many people live longer, more and more are afflicted by degenerative changes that affect their brain. These neurodegenerative diseases are usually relentlessly progressive and with time render patients incapable of many normal functions. For some families with certain genetic defects, these diseases occur aggressively and early. We would like to study the brains of patients from these families because in most cases the proteins affected by the gene defect have been identified. However, despite knowing this important information, the reasons for the death of brain cells are still not understood. This project will provide important new information on which brain cells died in these patients and on the relationship between such cell death and any cellular protein changes. By comparing patients with different genetic defects we will be able to identify the main cellular mechanisms underlying these degenerative changes. This information is essential for the rational design of further experiments aimed at reducing the suffering of all patients with neurodegenerative diseases or at eliminating these diseases altogether.Read moreRead less
My aim is to use advanced Neuroimaging to further our understanding of the pathophysiology of brain disorders, in particular Epilepsy, but also Sleep disorders, Schizophrenia, the Dementias. In the case of my main research interest (Epilepsy) it is to red
A Device For Simultaneous Continuous Acquisition Of EEG And MRI

$179,401.00
Summary
We aim to further develop a world-leading method we invented that facilitates the simultaneous, continuous acquisition of the electroencephalogram (EEG - electrical brain waves measured at the scalp) and functional Magnetic Resonance Imaging (fMRI - images the location of brain activity throughout the brain). Combining the two permits non-invasive imaging of human brain function with the exquisite temporal resolution of EEG and the high spatial resolution and brain coverage afforded by fMRI.
Development Of A New Surgical-guidance Tool For Intra-operative Tumour Margin Assessment In Breast Cancer

Funding Amount
$557,982.00
Summary
One third of breast cancer patients undergoing breast conserving surgery have insufficient tissue removed, resulting in an increased risk of recurrence. We have developed a high resolution optical imaging probe with the potential to detect small areas of cancer. It could be used to help guide the surgeon to remove all cancerous tissue from the patient. This grant will allow us to develop the probe to a stage that it can be used during surgery, and perform the world’s first clinical scans.
The Downstream Targets Of Patched/Hedgehog Signalling.

Summary
The patched-hedgehog gene pathway is disturbed in common human cancer, including basal cell carcinoma of the skin, medulloblastoma, rhabdomyosarcoma and ovarian fibroma. This application proposes to look at the genes turned off and on by the patched gene. By identifying these genes and examining their function we will identify the exact genetic disturbance which results in a large proportion of common human cancer. Once we find these genes this opens up the possibilities of designing drugs which ....The patched-hedgehog gene pathway is disturbed in common human cancer, including basal cell carcinoma of the skin, medulloblastoma, rhabdomyosarcoma and ovarian fibroma. This application proposes to look at the genes turned off and on by the patched gene. By identifying these genes and examining their function we will identify the exact genetic disturbance which results in a large proportion of common human cancer. Once we find these genes this opens up the possibilities of designing drugs which specifically block the action of the geneticdefect and thereby treating the tumours.Read moreRead less
Development Of Microscope-in-a-needle Devices For Improved Clinical Diagnostics

Summary
We have developed a new high-resolution optical imaging technology. The unique aspect of our research has been to redesign the imaging probe, miniaturising it to a few hundred microns in diameter, and encase it in a hypodermic needle – a ‘microscope-in-a-needle’. We are developing specific imaging probes to aid in the assessment of lung disease; the diagnosis of liver disease; and integrated into a brain biopsy needle to enable safer brain biopsies.
Advances in positron emission tomography now allow specific pathological features of many brain diseases such as Alzheimer's disease to be measured with a brain scan during life. This Fellowship will assist Professor Rowe and his team in their world leading work on new PET scanning techniques to improve diagnosis and assist the development of treatment for Alzheimer's and other degenerative diseases of the brain.
