The cost of these drugs to Medicare is expected to exceed $100 million p.a. over the next decade. A reproductive technology, which has always shown great potential to elevate some of this burden, is oocyte (egg) in vitro maturation (IVM), which drastically reduces the use-cost of drugs and the stress to patients. However, oocyte IVM has been slow to live up to its potential and the technology is still not in widespread clinical practice, mainly due to disappointing success rates in women. We have been studying oocyte IVM in animals for many years, and have recently made a significant technological breakthrough, improving success rates by ~50%. In this field, a 50% increase in efficiency is substantial and has significant clinical and commercial application. Currently, we are the only group worldwide with this technology. Over the course of this 2-year project we will conduct follow-up experiments to refine this discovery and investigate the feasibility of using this approach to treat human infertility. We are already in negotiations with two medical device manufacturers to licence this technology. We expect that this project will lead to a series of products and technologies that will enter a clinical trial for the treatment of infertility within 2-3 years.Read moreRead less

Summary
Aneurysmal disease is an age related phenomenon. The mean life expectancy of western populations has doubled in 100 years because of the reduction in deaths from preventable and treatable diseases, and prolongation of life with chronic and incurable diseases. The older community (>65 years) continues to be active and productive contrary to prior predictions. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community.

The mean life expectancy of western populations has doubled in 100 years because of the reduction in deaths from preventable and treatable diseases, and prolongation of life with chronic and incurable diseases. The older community (>65 years) continues to be active and productive contrary to prior predictions. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community. As with many other diseases, prophylaxis against aneurysmal disease is the most effective approach since 80% of those that rupture will result in death. Endoluminal grafting provides a much less invasive procedure and provides an attractive and elegant alternative to open surgery. The danger is that structural strengths will be compromised with failures due to lack of strength and inadequate device durability. The most practical endografts are those that are built up from modules but vulnerable sites affected by fatiguing and disruptive forces are being identified, in particular where a tube divides into two outflow channels – the bifurcation - and joins. To improve and protect the current device, and enable sound engineering for future devices, we need to know the nature, magnitude and location of these forces. The existing collaboration with medical specialist, Cook Aust., the Advanced Fluid Dynamics Laboratory (CSIRO, Melb.) and University of WA combines a multidisciplinary team working towards the design and durability of the next generation of endoluminal devices and percutaneous insertions. While Australia is at the forefront of development, its current place in the market can only be maintained by further product development. Optimising and improving endoluminal grafts will reduce the suffering of major surgery while prolonging a higher quality of life with a much less invasive procedure whose long-term effectiveness, and thereby acceptance is dependent upon reliable durability.Read moreRead less

The mean life expectancy of western populations has doubled in the last 100 years mainly because of the reduction in deaths from occlusive cardiovascular disease. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community. The impact of this work would be to improve minimally invasive, effective prophylaxis against aneurysm of the abdominal aorta since 80% of those that rupture will result in death. Endoluminal grafting provides a much less invasive procedure and provides an attractive and elegant alternative to open surgery. The general drive in this field is towards miniaturisation. The danger is that structural strengths will be compromised with early failures due to lack of strength; and late failures due to inadequate device durability. This application proposes the development of a collaborative venture with the Department of Vascular Surgery, Royal Perth Hospital, Cook R and D (WA), the Advanced Fluid Dynamics Laboratory (CSIRO, Melbourne) and Centre for Health Services Research (University of WA) to investigate the dynamic flow forces involved in aneurysms of the abdominal aorta. It combines together expertise and facilities to examine the forces acting upon endoluminal stent grafts in pulsatile high pressure environments, the impact on the design, patency, effectiveness and longer-term outcomes. The multidisciplinary team provides a comprehensive approach for this developing area of high technology surgery throughout Australia and internationally. The benefits of this study will directly influence the design and durability of the next generation of endoluminal devices and percutaneous insertions. While Australia is at the forefront of development, its current place in the market can only be maintained by further product development.Read moreRead less

Summary
In Australia approximately 2 million anaesthetic procedures are performed annually. Approximately one patient in 20,000 dies during or shortly after an anaesthetic from complications related to the anaesthetic itself, and as many as one in 170 suffers severe complications.

Approximately one patient in 20,000 dies during or shortly after an anaesthetic from complications related to the anaesthetic itself, and as many as one in 170 suffers severe complications. Mortality and severe morbidity are often ultimately associated with lack of oxygen in the tissues. Oxygen is transported from the lungs to the tissues by the blood. The oxygen content of arterial blood is monitored by pulse oximetry during every anaesthetic, but blood flow is not. Cardiac output is measured in only a very small proportion of anaesthetised patients using intravenous catheters that pass through the heart to the lungs. This procedure is invasive and is associated with significant morbidity and mortality. At present there is no easy way to monitor cardiac output non-invasively during anaesthesia. Our proposed research project, currently underway in conjunction with an industrial partner, is aimed at the development of a reliable, rapidly repeating, non-invasive method for monitoring total cardiac output and lung volume in every patient who has an anaesthetic. The purpose of the new monitor is to ensure that potential problems with oxygen supply to the tissues are detected and corrected promptly. Our new monitoring technique is computer-controlled, can function without intervention by the anaesthetist and has very few side-effects. It can be added to any anaesthetic machine. Such a measurement technique is likely to have an impact on anaesthesia similar to that of pulse oximetry in the 1980's, and, if suitably adapted, is likely to find applications in other fields, such as intensive care, sports medicine, the respiratory function laboratory and in veterinary medicine.Read moreRead less

It is planned to utilize this module in the design of customized new commercial PET scanners ideal for diagnosing human brain and breast disorders. The development will proceed in collaboration with Insight Oceania-ADAC, Sydney. Insight Oceania-ADAC are very excited by the potential applications and future markets (Australia and overseas) of the newly developing PET detection sub-modules for dedicated PET scanners. Positron Emission Tomography (PET) is a functional imaging tool, which is able to quantify physiological and biochemical processes in vivo, using short-lived cyclotron-produced radiotracers. PET is emerging as an extremely important diagnostic procedure used in the early detection of cancers, neurological diseases and as an aid in treatment monitoring and drug development. The unique advantage of PET over anatomical imaging techniques, such as X-ray CT and MRI, arises from its ability to measure changes in tumour biology, at the molecular level, prior to anatomical changes in involved tissues, using trace amounts of a radiolabelled compound (radiotracer). The full potential of PET however, is not being completely utilized due to constraints within the current designs of PET scanners. When used to its full potential PET, in principle, would be an excellent diagnostic and treatment monitoring tool for breast cancer, brain tumours and other neurological conditions such as epilepsy, Alzheimer's, Parkinson's disease, post stress disorder, dementia, and depression. Lack of flexibility in current PET scanner designs to date has meant that no commercial human brain or breast imaging scanners exist. Pilot project data proved the feasibility of our new flexible PET detection module design.Read moreRead less
