Summary
Disseminated cancer, unlike the localized disease, can rarely be cured by drug therapy. We have found that LIM kinase (LIMK1), a protein that was discovered in our laboratory, plays an important role in controlling the ability of tumour cells to spread, a process called metastasis. Thus, this protein becomes an important target for the development of new drug therapies to prevent the spread of cancer.

We have found that LIM kinase (LIMK1), a protein that was discovered in our laboratory, plays an important role in controlling the ability of tumour cells to spread, a process called metastasis. Thus, this protein becomes an important target for the development of new drug therapies to prevent the spread of cancer. Importantly, we have demonstrated that (1) inhibiting LIMK1 blocks the formation of metastatic tumours in mice, and (2) introduction of this protein into tumour cells makes them more invasive. In addition, we find that the level of LIMK1 is much higher in human tumour cell lines that have the propensity to easily form tumours in mice. Also, measuring the level of this protein in cancer cells that spread to other organs shows that it is at significantly elevated levels when compared to normal tissue. The goals of this research are to: (1) understand whether the ability of LIMK1 to regulate tumour spreading and invasiveness correlates with its ability to control metastasis; (2) examine in human tumour samples whether the levels of LIMK1 correlate with the development of metastatic tumours; and (3) search for drugs that can inhibit the activity of this protein. The results from this research will be highly significant because LIMK1 levels are likely to be an important marker for which tumours will become metastatic. It is possible that, at the time of tumour diagnosis, LIMK1 measurements will enable the clinician to predict whether an individual tumour will become metastatic. Secondly, this protein is a novel drug development target. Drugs that inhibit this protein may block the ability of tumours to invade and metastasise.Read moreRead less
A Randomised Controlled Trial Of Cognitive Bias Modification Training During Early Recovery From Alcohol Dependence

Summary
Relapse to alcohol dependence often occurs within days of detoxification, partly because alcohol-dependent people are easily triggered to approach alcohol-related cues. Computerised “brain-training” programs may reduce this “approach bias”, reducing risk of relapse. We aim to conduct a multi-site trial testing the effects of this training on alcohol relapse, and to estimate the savings to the health care system that could be achieved by conducting this treatment during inpatient detoxification.
The Role Of Interferon Signalling In The Regulation Of Stroke

Summary
This project focuses on the role that inflammation plays in the progression of the type of neural injury seen in stroke victims. This project targets a specific pathway that is thought to be involved in the regulation of general inflammation but has not been greatly investigated in terms of the neural injury seen in stroke. Understanding the actions of this pathway may lead to future therapies that can be used to prime the brain to react in a positive way to stroke.
Circuit Class Therapy For Rehabilitation Clients. A Pragmatic Randomized Controlled Trial Of Therapy Intensity (CIRCIT).

Summary
Loss of independence is common after stroke, and may lead to reduced quality of life and admission to nursing home care. We will investigate if an increased amount of rehabilitation following stroke leads to improved mobility. Two ways of delivering more intense rehabilitation will be compared with usual care to find out which leads to improved physical mobility, and how they compare economically. This will allow health service providers to optimise services and will benefit people with stroke.

Summary
The ten scientific laboratories in this program have joined forces to investigate two ways in which tumours develop. Both are of particular interest, because they suggest new ways in which cancer might be overcome. Most of our tissues are continually renewed throughout life by production of new cells. Therefore many of the old cells in each tissue must die off to maintain the proper cell numbers. To eliminate cells that are no longer needed or have become damaged, the body has developed a remark ....The ten scientific laboratories in this program have joined forces to investigate two ways in which tumours develop. Both are of particular interest, because they suggest new ways in which cancer might be overcome. Most of our tissues are continually renewed throughout life by production of new cells. Therefore many of the old cells in each tissue must die off to maintain the proper cell numbers. To eliminate cells that are no longer needed or have become damaged, the body has developed a remarkable cell suicide process termed apoptosis. Unfortunately, however, occasionally a random accident to the genes in one of our cells prevents the machinery for apoptosis from being turned on. In that case, the cell will not die when it should and, by continually dividing, it may eventually give rise to a cancer. Since most cancer cells still retain most of the machinery for apoptosis, however, a drug that could switch on this natural cell death machinery would provide a promising new approach to cancer therapy. Identifying and developing such drugs is one major long-term goal of this program. The other focus of our program concerns stem cells. These are rare cells with the remarkable ability to generate an entire tissue. For example, one of our laboratories has identified stem cells that can generate all the cells in the breast. The almost unlimited regenerative capacity of stem cells has a built-in danger. If a stem cell acquires the ability to proliferate excessively, it can go on to form a tumour. Indeed, many cancer researchers now suspect that rare stem cells within a tumour cause its inexorable growth. If tumour growth is maintained by stem cells, it will be essential to develop new forms of therapy that target these rare cancer stem cells rather than merely the bulk of the tumour cells. This is another key long-term goal of our program.Read moreRead less
Young women negotiating from the margins of education and work: towards gender justice in educational and youth policies and programs. Young women who leave school early are the most economically disadvantaged young people in the labour market.

Young women who leave school early are the most economically disadvantaged young people in the labour market. We will investigate the educational, labour market, biographical and social experiences of these young women, and their inter-actions with teachers and youth service providers. We will identify trends, differences and similarities across rural and urban locations and across generations, and develop a profile of factors and programs most likely to help these young women negotiate their post-school lives. The research findings will enrich gender justice and social theory and contribute to policy and program development in the education and youth services sectors.

Summary
The distribution of medical services and its impact on access and equity is widely recognised as a key concern of the Australian community. Access and equity are key indicators to the public of the performance of a health system. These concerns have led to the adoption of major policy goals under Medicare relating to equitable access to medical services for the population as a whole.

Access and equity are key indicators to the public of the performance of a health system. These concerns have led to the adoption of major policy goals under Medicare relating to equitable access to medical services for the population as a whole. Furthermore, both the community and policy makers have expressed high levels of concern over the distribution of medical services between sub-markets and sub-populations, in particular, in the distribution of medical services between urban and rural-remote areas. This project, for the first time, comprehensively examines the performance of Medicare in terms of access to medical services over time. Australian data sets, largely untapped by economic modelling, will be used for analysis of the relationships between the distribution of, access to, and demand and fees for Australian medical services and their impact upon mortality over time. The study will result in the first comprehensive Australian description of access and supply of different medical services by social group and by geographic location over time. Furthermore it will provide evidence on the key determinants of distribution and changes in the distribution of medical services and estimates the likely effects of policy instruments designed to address the distribution of, and access to, medical services.Read moreRead less
