Summary
A unique test that monitors the rate of switching between the hemispheres of the brain in response to visual stimuli has been devised. A patent application covers an apparatus and test to measure the switching rate between the hemispheres and the way in which such measurements can be used as a means to diagnose bipolar disorder (BD).

A patent application covers an apparatus and test to measure the switching rate between the hemispheres and the way in which such measurements can be used as a means to diagnose bipolar disorder (BD). BD, also called manic depression, is a form of depression that currently affects over six million people worldwide with about three million in the USA alone. The condition has phases of mania and depression and periods of remittance. Full cycles of BD can occur as many as three times a year and for many patients, this is a lifelong condition. BD is effectively treated, once it is diagnosed. It is estimated that 20% of sufferers go undiagnosed and many more are misdiagnosed. The cost of mis- or non-diagnosis is measured by suicides, the financial burden on society with health care, loss of productivity etc, effects on family and associates, crime, etc. Diagnosis to date is achieved mainly by subjective means such as questionnaires. These instruments do not conclusively separate BD from other forms of depression and schizophrenia, for which treatment is quite different. Nor do they allow for factors such as substance abuse and other medical conditions that the patient may be suffering. BD is hereditary with the slow hemispheric switch rate being an indicator of the genetic trait. This phenomenon allows for an objective test for BD, even if an individual has not had an episode of BD. The slow switch allows relatively easy separation of a BD patient from those exhibiting symptoms that may have other causes.Read moreRead less
NaviGAIT: New Software To Simplify Interpretation Of Gait Analysis Data

Funding Amount
$179,905.00
Summary
NaviGAIT is a new software package to support interpretation of gait analysis data. It is based upon Gait Profiling, a new technique to reduce the complexity of such data. At present data intepretation is restricted to a few expert clinicians. The new software will allow non-expert clinicians to interpret data and hence make gait analysis more accessible, cheaper and more clincally useful. A module of NaviGAIT specifically for children with cerebral palsy will be the first to be developed.
Non-invasive Measurement And Imaging Of Hepatic Iron Concentrations Using Nuclear Magnetic Resonance

Summary
Iron overload diseases such as genetic haemochromatosis and thalassaemia affect up to 0.5% of the world's population. These diseases result in deposition of dangerously high concentrations of iron in tissues of the body. Organs such as the liver and heart are at particular risk of being damaged. In order to manage a patient's condition optimally, a knowledge of their tissue iron concentrations is required. Currently the most direct and reliable way of achieving this is to remove a small sample o ....Iron overload diseases such as genetic haemochromatosis and thalassaemia affect up to 0.5% of the world's population. These diseases result in deposition of dangerously high concentrations of iron in tissues of the body. Organs such as the liver and heart are at particular risk of being damaged. In order to manage a patient's condition optimally, a knowledge of their tissue iron concentrations is required. Currently the most direct and reliable way of achieving this is to remove a small sample of the patient's liver for chemical analysis. Apart from the fact that the procedure is unpleasant and carries some risk, the measurement made by this method has some uncertainty because the liver iron concentration can vary significantly from place to place within the liver. The aim of this project is to test the validity of a new non-invasive method of measuring and imaging the liver iron concentrations of a patient. In addition, the potential to use the new technology for detecting and imaging liver cirrhosis in iron overloaded patients will be evaluated. If successful, the project may lead to a more accurate method of measuring tissue iron concentrations and eliminate the need for invasive procedures.Read moreRead less
Web-based Multimedia Information Management System For Use In Remote Diagnosis Of Eye Diseases

Summary
Our aim is to develop a web-based multimedia information management system for use in remote diagnosis of eye diseases. The proposed system will provide medical advice and diagnosis, information and distance education for those working in health care as well as the community, computer-aided diagnosis and assistance in the operational and medical decision-making process. Less expensive health care personnel should be able to use the system with little training in remote and rural areas.

Less expensive health care personnel should be able to use the system with little training in remote and rural areas. Significantly, the project should empower remote general doctors and nurses by proper access to expert advice, save many remote patients from unnecessary visits to specialist centres on the one hand and allow more proper diagnosis and intervention on the other. It has the potential for significant reductions in the cost of health care delivery, should strengthening the bond between medical services in remote and city areas, provide training and education of local GPs, nurses, health care workers and optometrists and provide web-based disease management systems will provide instant access to health care information. The outcomes of this project are potentially of great significance to remote and rural communities in Australia and around the world. There will be an enormous impact on current health care practices.

Funding Amount
$599,142.00
Summary
The development of a low-cost miniature drug delivery platform for the treatment of chronic respiratory diseases is proposed. The portable device has already been shown to be significantly more efficient than currently available asthma inhalers. In addition, the device offers the possibility of dose adjustment to account for patient variability, such as age and disease severity, as well as a reduction in patient intervention, thus making it more appropriate for patients unable to self-medicate.

Summary
We seek to develop an ocular implant for the treatment of bacterial endophthalmitis. The implant will be a small device that can be administered directly to the affected ocular cavity to release an antibiotic in a controlled manner to clear any infection. The implant will erode and leave no residue. It will be produced from a novel drug-polymer conjugate technology that allows polymer devices that comprise >50% drug to be made.

Choroidal neovascularisation, which is the most severe form of Age Related Macular Degeneration, is the major cause of blindness in the developed world. Gene therapy could be a cure for this disease if the problems associated with the delivery of DNA could be addressed.

Our project involves a highly novel strategy for gene delivery involving ion pair formation of lipophilic dendrimers (tree-like compounds with positive charges on the surface). We will develop new DNA-dendrimer complexes and test them in a well established animal model for neovascularisation. Successful completion of this project might offer a potential therapy for choroidal neovascularisation, with a good chance of entering into human clinical trials.Read moreRead less

Summary
Age-related macular degeneration (AMD) is the leading cause of visual loss for adults in the developed world. Treatment is now by needle injection into the back of the eye, which is painful for the patient and is costly for the health-care system. Seagull Technology Pty Ltd has developed a non-invasive device for treating the back of the eye without the need for a needle injection. This project will test the new device in animals and then move to a first safety study for human AMD patients.
