Summary
The persistence of breathing problems from infancy to later life is a complication of premature birth with lifelong consequences. Breathing problems often occur together with lung disease, but prematurity can also affect heart and blood vessel development, and weakness of the main breathing muscle. We will find out how much the heart, lungs and diaphragm contribute to breathing problems in babies; helping us to better predict, diagnose and treat severe breathing problems in babies born preterm.
Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing resu ....Models of Knowledge Restructuring. In a world of rapid change, people must frequently adapt cognitive skills to new technologies. This often requires restructuring of knowledge, from simple initial strategies to increasingly complex ways of mastering the task. This is not always easy and people sometimes resist knowledge restructuring. We present a network model of knowledge restructuring that combines attentional processes with error-driven learning. The model accounts for several existing results and makes predictions that guide the proposed research. Three factors will be examined empirically: (1) the role of directing attention to alternative strategies; (2) the imperfection of existing knowledge; and (3) the complexity of alternative strategies.Read moreRead less
Advancing the science of willpower: investigating the mechanisms and processes of self-control. Willpower or 'good' self control is important for success in our academic, occupational, and social lives. This project will use cutting-edge scientific methods to investigate how glucose, the primary fuel for body function, promotes 'good' self-control and stimulates regions in the brain important for self-control.

Alzheimer's disease (AD) is a major cause of dementia in the elderly. As populations worldwide are living longer the prevalence of AD is predicted to rise markedly and in addition to the huge emotional burden on families the economic implications to the community at large is severe.

As populations worldwide are living longer the prevalence of AD is predicted to rise markedly and in addition to the huge emotional burden on families the economic implications to the community at large is severe. Thus our aging veteran population and their spouses are particularly vulnerable to this devastating disease. Recent developments in AD research have resulted in a number of therapeutic strategies being undertaken with several of these now in phase 2 clinical trials. However for these treatments to be most effective early diagnosis is crucial. Currently, definite diagnosis is restricted to post-mortem examination of the brain for the presence of characteristic neuropathological features. This project proposes to identify individuals at high risk of developing cognitive decline leading to AD by using a battery of biochemical, genetic and neuropsychological markers. This study builds on our earlier work which followed a cohort of memory complainers and demonstrated that subjects in this group have lower cognitive scores and an increased frequency of the genetic risk factor, the e4 allele of apolipoprotein E. Follow up of this well studied cohort with more sensitive and extensive neuropsychological tests together with other genetic and biochemical markers will be important in identifying those risk factors that have positive predictive value for cognitive decline thereby contributing towards enhancing the therapeutic efficacy of current symptomatic and future drugs directed at the cause of AD.Read moreRead less
Do Exposures Before Conception Influence The Risk Of Asthma In Offspring?

Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
DYRK1A As A Novel Target For Glioblastoma Therapies

Summary
Glioblastoma is a form of brain cancer that is currently incurable. We have discovered that switching-off an enzyme called DYRK1A (using ‘DYRK1A inhibitors’) kills glioblastoma cells. This therapeutic advantage is even greater when combined with drugs approved for other cancers. This project will develop new DYRK1A inhibitors and examine a novel combination treatment for glioblastoma patients. This could initiate a novel therapy that could significantly extend patients’ lives.
The health effects of electronic cigarette use are virtually unknown. They have only recently been introduced into widespread use, and as such their effects on human health will not be known for many years. We will use our expertise in exposure models and health outcome measurement to provide timely hard-data on their potential to impact health – data that are urgently required to guide policy makers in this area.
Exercise As Medicine For Heart Failure: A Novel Intervention To Improve Outcomes

Summary
Heart failure (HF) is a common, debilitating and expensive disease; prognosis remains poorer than for the most cancers. 30,000 Australians are diagnosed every year and 300,000 live with the HF, at an annual cost of ~$1Billion. Exercise training is effective therapy in HF, because it reverses many of the problems that contribute to the reduced lifespan and impaired quality of life of patients with HF. We will test an exciting new type of exercise that promising greater benefit, at lower risk.

Summary
Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens.

Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. However, many infants who wheeze with viral infections, especially in the first year of life, do not develop allergies in later life, raising the possibility that they did not have the same type of asthma as those whose symptoms persist. This project will study the effects of viral infections on lung function to determine whether particular types of virus can have detrimental effects of lung function lasting for years. We will also examine whether the age at which the infection occurs and the severity of the infection influence the long-term outcome. The project involves studying infants during the recovery phase of respiratory viral infections, older children years after documented infections and experimental animal models that have been infected under controlled conditions. By determining whether respiratory viral infections can have long-term effects on lung function that can mimic asthma, we will advance our understanding of how asthma develops. In addition, specific treatment and preventative strategies could then be developed to prevent these long-term abnormalities, instead of relying on asthma medication (especially inhaled corticosteroids) as is the current practice. Preventative strategies could include encouraging the development of specific vaccines.Read moreRead less

Summary
The Raine study is a unique long term experiment that has collected extensive pre-birth and childhood data in ~3000 young Australians, who are now 27 years old. We plan to measure the artery health of 1200 of these volunteers and to determine what factors, both before and after birth, influence the presence of early atherosclerosis in humans. This study will guide strategies aimed at early prevention of heart attacks and stroke in humans, by defining the major risk factors.
