Summary
Age-related macular degeneration (AMD) is a major cause of visual impairment in advanced countries, responsible for nearly half of all legal blindness in Australia. Due to increased life expectancy, the number of people with this progressive late onset disease will double by 2025. Aspirin could prevent or delay the onset of AMD in older persons but its bleeding risk also needs to be considered.

Summary
Cough is the most prevalent symptom of lung disease and the most common reason for people to seek medical advice. However, cough neural processes are poorly defined and as a result current cough therapies are largely ineffective making cough a significant unmet clinical problem. This project will novel viral strategies to dissect and manipulate cough neural pathways in the brain, providing insights into the neural processing of airway sensations and coughing.
Exploring Scanning Ultrasound (SUS), A Novel Method To Treat And Prevent Neurodegenerative Disease

Summary
We developed a novel scanning ultrasound (SUS) protocol that clears toxic protein aggregates and restores memory function in mouse models of Alzheimer's disease (AD), without the need for therapeutic agents. Here we aim to determine whether SUS has preventative potential, whether there are synergistic effects, and whether a therapeutic antibody combined with SUS leads to an enhanced therapeutic outcome. Together this will guide the development of an ultrasound therapy in AD patients.
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.
The Fetal And Early Childhood Origins Of PCOS: A Prospective Cohort Study

Summary
The Polycystic Ovary Syndrome (PCOS) affects up to 10% of women of reproductive age, which translates into around 350,000 women in Australia. It is the most common hormonal disorder in women. The syndrome has far-reaching adverse implications for general and reproductive health, including menstrual disorder, obesity, infertility, miscarriage, pregnancy complications, increased risk of diabetes and possibly heart disease. PCOS also commonly causes cosmetic problems such as excess body hair and ac ....The Polycystic Ovary Syndrome (PCOS) affects up to 10% of women of reproductive age, which translates into around 350,000 women in Australia. It is the most common hormonal disorder in women. The syndrome has far-reaching adverse implications for general and reproductive health, including menstrual disorder, obesity, infertility, miscarriage, pregnancy complications, increased risk of diabetes and possibly heart disease. PCOS also commonly causes cosmetic problems such as excess body hair and acne. The underlying causes of PCOS are not known but are thought to arise during intrauterine (fetal) life and to be modified by aspects of childhood health, particularly overweight and obesity. Using a large and well established cohort of adolescents followed up since fetal life and throughout childhood and currently aged 13-15 years old (the Raine cohort), we will define for the first time the intrauterine and early childhood correlates of PCOS. PCOS will be diagnosed by a specialist gynacologist using current international criteria. We will then utilise extensive existing data from this cohort combined with new measurements on existing samples to determine the contribution of key factors including fetal growth restriction, low birth weight, fetal androgen exposure, rapid postnatal growth, childhood adiposity, elevated fasting glucose and insulin and age at menarche to PCOS. In this way, we will address for the first time the hypothesis that PCOS arises as a result of events during fetal life and is affected by factors during childhood. The results from these studies will improve our understanding of PCOS and eventually improve reproductive and metabolic health for a substantial population of women internationally. It is essential that these studies are conducted as soon as possible or the opportunity will be missed. Girls with persistent menstrual irregularity are likely to be commenced on hormonal treatments which will make the diagnosis of PCOS impossible.Read moreRead less

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
