Summary
Peritoneal dialysis (PD) is a form of home dialysis that is both substantially cheaper and associated with better early survival than standard hospital-based haemodialysis. Its use in Australia has been severely limited by poor outcomes compared to the rest of the world. This international study aims to identify “real world” PD centre practices that will lead to better outcomes for Australian patients, greater uptake of home dialysis and health savings of tens of millions of dollars annually.

Preterm birth is a major problem in our society, and has enormous consequences for parents and children. It also has a major impact on scarce financial resources. When women present in preterm labor, current therapies have only limited success in stopping contractions and postponing birth.

It also has a major impact on scarce financial resources. When women present in preterm labor, current therapies have only limited success in stopping contractions and postponing birth. They have not been shown to reduce the rates of the serious neonatal problems associated with prematurity. This project will be coordinated in Newcastle, N.S.W., and will involve major perinatal centres throughout Australia, along with overseas centres. It will test a new combination of drugs for their ability to postpone delivery in women presenting with preterm labour. It is postulated that the combination of drugs will be more effective than existing therapies. The drugs used in the trial are Nifedipine and Rofecoxib. Complications of prematurity include neonatal death, cerebral palsy, visual and hearing impairment, and chronic lung disease. These complications are most significant in extremely premature infants - in particular, those under 28 weeks gestation at the time of their delivery. For this reason, the study will focus only on women presenting in labour below 28 weeks. The ability to stop labour is important, but the main aim of any treatment for preterm labour is to reduce the rates of neonatal death and handicap. Babies born to women enrolled in this study will be followed for a period of one year after birth to assess their outcomes. It is our hypothesis that the combination of Rofecoxib and Nifedipine will result in lower rates of death and handicap in babies than Nifedipine alone. In addition, we will examine the rates of side effects in women receiving therapy. Currently used therapies, including intravenous ventolin, have high rates of maternal side effects. Nifedipine and Rofecoxib have both been shown to have low rates of maternal side effects.Read moreRead less
Optimal Duration Of Neoadjuvant Androgen Deprivation Therapy In Localised Prostate Cancer

Summary
Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer ....Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer of the prostate that has spread throughout the body for the last five decades, worldwide. It remains uncertain however whether AD administered before surgery or radiation will benefit any of the 8000 men each year who develop localised cancer by shrinking the cancer first. In 1996 a trial involving 800 men across Australia and New Zealand commenced under the auspices of the Trans-Tasman Radiation Oncology Group (TROG) to answer the questions: 1 - Does either 3 or 6 months AD prior to radiotherapy reduce the chances of recurrence of the cancer after radiotherapy? 2 - Does such therapy reduce the volume of tissue requiring radiotherapy and hence the chances of long term side effects after radiotherapy? This grant will support collection of follow-up information from the trial and hence answers to the questions asked.Read moreRead less
An International Clinical Trial To Evaluate New Therapies To Improve Survival Of Children With Relapsed Acute Lymphoblastic Leukaemia

Summary
Children who relapse with childhood leukaemia have only a 50% chance of being alive after 5 years. We will participate in a new international trial involving most European and all Australian and New Zealand childhood oncology centres, to test the effectiveness of promising new treatments and to perform biological studies which should enable doctors in future to pick the best treatment for each of these patients.
Dissecting a hematopietic transcription factor complex. The development of mature active cells is a highly complex and coordinated process that is controlled largely by groups of interacting regulatory proteins. We are trying to understand, at a very detailed level, how a specific group of these proteins interact to regulate both normal blood cell development and the onset of childhood leukemias. Using this information we will try to develop reagents that can be used to inhibit these interaction ....Dissecting a hematopietic transcription factor complex.

We are trying to understand, at a very detailed level, how a specific group of these proteins interact to regulate both normal blood cell development and the onset of childhood leukemias.

This proposal will further our understanding of mammary gland development and lactation and the mechanisms controlling mammary cell fate decisions such as differentiation. Regulation of cell fate lies at the core of most aspects of cell biology from normal development to dysfunction such as cancer. The knowledge gleamed from this project also has the potential to make economic gains for Australia by increasing the profitability and ensuring the sustainability of both the dairy and meat industries. Better understanding of the mechanisms controlling mammary epithelial cell differentiation should enable augmentation of lactation such as increasing milk protein content, using marker assisted selection (of targets such as Runx2) in cattle.Read moreRead less
Oxidative Damage and Cell Ageing. This research will benefit Australia by providing a fundamental understanding of how cells age. This will have immediate international impact at the scientific level and will inform strategies to reduce the rate of ageing and alleviation of age-related disorders. In the longer term the research may provide commercial and social outcomes by identifying antioxidant systems that will provide a genuine benefit in reducing ageing.
Cellular Responses to Oxidative Damage: Cell Aging. The aim of this project is to identify the mechanisms by which oxidative stress and free radical damage cause cell aging. This work will make a significant contribution to our understanding of the aging process in cells by identifying the major reactive oxygen species that contribute to cell aging, which defence systems and antioxidants provide the greatest degree of protection, what damage accumulates as cells age and which genetic systems ar ....Cellular Responses to Oxidative Damage: Cell Aging.

The effect of nitrogen monoxide on intracellular iron metabolism. We discovered that the crucial signalling molecule nitrogen monoxide (NO) mediates iron (Fe) and glutathione (GSH) release by the transporter MRP1 probably as an NO-Fe-GSH complex [DR(2006) PNAS USA 103:7670-5]. During our current ARC grant we have markedly extended these findings by showing that another molecule, GST Pi and MRP1 form part of a coordinated system that stores and transports NO as complexes of Fe and GSH, markedly e ....The effect of nitrogen monoxide on intracellular iron metabolism. We discovered that the crucial signalling molecule nitrogen monoxide (NO) mediates iron (Fe) and glutathione (GSH) release by the transporter MRP1 probably as an NO-Fe-GSH complex [DR(2006) PNAS USA 103:7670-5]. During our current ARC grant we have markedly extended these findings by showing that another molecule, GST Pi and MRP1 form part of a coordinated system that stores and transports NO as complexes of Fe and GSH, markedly extending NO half-life from milliseconds to hours. This has broad implications for understanding NO activity in many processes which have major vital health implications, including tumour cell killing by macrophages and blood pressure control.Read moreRead less
