Pathologies of the cardiovascular system arising from heart diseases make a major contribution to morbidity and mortality in the Australian community. This project will provide new diagnostic modalities based on advanced noninvasive bioinstrumentation, signal processing and model-based analytical methods to identify early signs of developing disease or the acute exacerbation of existing disease. The impact of these new technologies on the early diagnosis and improved triaging of patients in emergency departments is potentially profound and could result in improved healthcare outcomes for the patients and reduced admissions to hospital as well as the development of a substantial international market.Read moreRead less

Summary
We are trialling the implementation of an innovative telephone-delivered program for managing people who have had a heart attack. Cardiac rehabilitation programs are generally based in hospitals in Australia and people have to be able to attend the programs when they are offered. Even though such programs have been shown to be very effective in improving outcomes after a heart attack, at least 85% of Australians after a heart attack are either unable to access and-or unable to attend such progra ....We are trialling the implementation of an innovative telephone-delivered program for managing people who have had a heart attack. Cardiac rehabilitation programs are generally based in hospitals in Australia and people have to be able to attend the programs when they are offered. Even though such programs have been shown to be very effective in improving outcomes after a heart attack, at least 85% of Australians after a heart attack are either unable to access and-or unable to attend such programs due to transport and many other barriers. So, there is an urgent need to identify new, effective, and affordable ways of delivering cardiac rehabilitation programs to people after a heart attack. The proposed telephone-delivered program will be particularly appropriate for disadvantaged people, such as those living in rural and remote areas as well as Indigenous Australians, who do not currently have access to hospital-based cardiac rehabilitation programs. People who have had a heart attack will be recruited from three of Brisbane's largest public teaching hospitals, and will then be randomly assigned to the telephone-delivered cardiac rehabilitation program (Care Management Intervention group) or to a control or Usual Care group. The Care Management Intervention group will receive regular telephone calls from a highly qualified 'Care Manager' based at the renowned National Heart Foundation of Australia telephone support service, 'Heartline'. The Care Manager will help people to manage their heart condition and prevent the reoccurrence of further heart problems. People will also be encouraged to make necessary lifestyle and behavioural changes with the assistance of the Care Manager and some Heart Foundation educational and interactive resources to record their progress. We expect that the program or Care Management Intervention group will have better health outcomes than the control or Usual Care group at 6 and 12 months follow up.Read moreRead less
Pre-clinical evaluation of snake venom proteins with therapeutic potential. Australia harbors some of the most toxic snakes in the world. Their venoms contain a range of substances that are designed to rapidly immobilize and kill their prey. These include agents that lead to enhanced blood clotting; excess bleeding. We have isolated and characterized a large number of the components involved over the last several years. The aim here is to carry out pre-clinical trials in animal models to test th ....Pre-clinical evaluation of snake venom proteins with therapeutic potential. Australia harbors some of the most toxic snakes in the world. Their venoms contain a range of substances that are designed to rapidly immobilize and kill their prey. These include agents that lead to enhanced blood clotting; excess bleeding. We have isolated and characterized a large number of the components involved over the last several years. The aim here is to carry out pre-clinical trials in animal models to test the efficacy of three proteins as anti-bleeding agents and investigate several other novel components. The ultimate outcome will be the development of novel drugs that will have application in the treatment of human disorders. Read moreRead less
Dynamics of Locomotion: Visualisation in skill acquisition & rehabilitation. How does visual information and attention determine the control and coordination of locomotion? Using large-screen projection of computer graphics and immersive virtual reality, we will examine the influence of visual information on driver training, gait in the elderly, cardiorespiratory control, and the attentional interference of mobile phones on driving. Experiments will be based on principles from dynamical and comp ....Dynamics of Locomotion: Visualisation in skill acquisition & rehabilitation. How does visual information and attention determine the control and coordination of locomotion? Using large-screen projection of computer graphics and immersive virtual reality, we will examine the influence of visual information on driver training, gait in the elderly, cardiorespiratory control, and the attentional interference of mobile phones on driving. Experiments will be based on principles from dynamical and complex systems theory and will inform the design of innovative algorithms for autonomous mobile robots. Expected outcomes include improved road safety, new methods for the rehabilitation of those with gait disorders, and a deeper understanding of the physiological response to virtual exercise.Read moreRead less
Stress-sensing and cytoprotection in ageing and disease. This project aims to unravel the mechanisms responsible for age- and disease-related responses to heart attacks and the efficacy of therapeutic approaches, while deepening our understanding of a novel, potent protective modality effective in aged hearts. This program will provide valuable basic knowledge, leading to more efficacious therapies.

In an era where Australia's national security reliance on geographic isolation and support from allied forces are being challenged, the research outcomes of this project will play an important role in understanding the capabilities of hypersonic systems. The project will also have significant spillover benefits into other complex system domains, where computational tools can be used to aid in design leading to high embedded-IP products for Australian industry. Furthermore, the proposal encompasses a strong research training aspect, with graduates exposed to leading edge industry and academia.Read moreRead less
Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry.

An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index in turbid media, including biological tissue in vivo. We propose to apply our novel technique to study tissue calcification, a serious problem in cardiology, by making use of the refractive index contrast mechanism. Calcification of smooth muscle cells and aorta subdermal implant models will be studied aiming for prevention of calcification-associated pathologies.Read moreRead less
Enhancing Erythropoietin Therapy In Ischaemia-reperfusion Injury Of Heart And Kidney
Funder

Funding Amount

Summary
Heart attacks and kidney disease from a lack of blood flow are common causes of morbidity and have poor treatment options. Erythropoietin (epo) is a useful new treatment, but there remain some caveats to its use in humans: eg. it may cause excessive scarring during repair. Use of epo with an anti-inflammatory drug may decrease scarring and provide benefit to long-term health. We plan to carefully define the biomolecular pathways of injury and repair, to better plan this therapy for human use.
