Summary
The use of morphine as an analgesic is still limited by undesirable side effects such as tolerance. Despite decades of research, the mechanisms behind the development of tolerance are poorly understood. The ? opioid receptor is a protein expressed at the surface of the cells that is the target of morphine. This project will investigate the signalling events triggered by opioids with unprecedented resolution and will aim to elucidate why morphine elicits more tolerance than other opioid drugs.
A Multicentre Randomised Clinical Trial Of Physical Activity For The Treatment Of Patients With Alzheimers Disease

Summary
The number of older adults living with Alzheimer's disease (AD) will increase from 26.6 million to 106.2 million by 2050. In the absence of curative treatment options it is important to focus on non-pharmacological interventions such as physical activity. We propose to investigate whether a home-based physical activity program of 24 weeks for patients with AD can successfully decrease the rate of cognitive and functional declince and improve quality of life and psychological well-being.
Interactions Between RAGE And The Type 1 Angiotensin Receptor Determine The Pro-atherosclerotic Actions Of Angiotensin II

Summary
Heart attacks and strokes are a major cause of death and disability in Australians. Activation of the renin angiotensin system plays a key role in the development and progression of atherosclerosis, the process that leads to narrowing and obstruction of arteries. In preliminary data we have found a way to block these pathways without affecting the control of blood pressure. We believe that interventions based on these data will be important for the prevention and treatment of heart disease.
Predictors And Correlates Of Health-related Quality Of Life And Morbidity In Overweight/obese Adolescents: Cohort Study

There is now no doubting the size and long-term risks to health of the childhood obesity epidemic. However, very little research has examined at population level its immediate consequences for mental health and physical functioning, what pathways confer risk and protection for these consequences, and their likely healthcare consequences.

However, very little research has examined at population level its immediate consequences for mental health and physical functioning, what pathways confer risk and protection for these consequences, and their likely healthcare consequences. This study will utilise an existing cohort of approximately 1500 Victorian adolescents followed since childhood to examine neglected aspects of the genesis and impacts of overweight and obesity. The Health of Young Victorians Study was originally assembled in 1997 when the children were in Grades Prep-3. In addition to information on putative risk and protective factors for overweight-obesity and direct measures of height and weight, it is unique in having collected data on health-related quality of life (HRQoL) since children were first recruited during the early primary school years. Eight years after the first wave, the children will be adolescents in Grades 8-11. This third wave will retain a focus on HRQoL. Innovations include study of potential emotional, behavioural and physical consequences of childhood obesity that may in turn affect the natural history of obesity. This large, population-based longitudinal study will redress neglected aspects of child and adolescent overweight-obesity specifically identified in 2003 by the NH and MRC. As well as establishing whether a range of common problems are related to overweight-obesity, it will be able to shed light on mechanisms of adverse outcomes associated with adolescent overweight-obesity, and study protective factors predicting remitting overweight from childhood to adolescence that may inform preventive activities. The study will make an international contribution to knowledge about pathways, prevalence and preventive opportunities for child and adolescent overweight-obesity.Read moreRead less
Directed Molecular Evolution Of G Protein-coupled Receptors For Stable And Functional Expression In Escherichia Coli

Summary
Approximately half of all prescription drugs on the market act on G protein coupled receptors (GPCRs). The mechanisms underlying GPCR function are mainly unknown due to a lack of structural information. No solved structures exist for any of the estimated 800 human GPCRs, making it difficult to design new drugs. By applying advanced protein engineering techniques I aim to produce human GPCRs in bacteria to ultimately acquire structural information, which will enable novel drug development.
Structural Events In Insulin And IGF Signalling - A Nanodisc Approach To A Problem In Cancer, Diabetes And Alzheimer's Disease

Summary
Insulin and its insulin-like growth factors play a major role in three major disease states facing ageing Australians—diabetes, cancer and Alzheimer's disease. We aim to understand how these proteins send messages into cells via their so-called receptors. We will isolate the receptor molecules from cells and then image them in an advanced electron microscope to produce three-dimensional images. Our findings will have implications for the design of therapeutics targeting the above three diseases.
Scalability Of The Transform-Us! Program To Promote Children's Physical Activity And Reduce Prolonged Sitting In Victorian Primary Schools

Summary
Transform-Us! is an innovative primary school program that has been found to substantially increase children’s physical activity levels, reduce sitting time and benefit health. With simple changes to the school and classroom environments and teaching practices (eg, standing lessons) we will work with partners in the education and health systems to translate this program across Victorian primary schools to determine the real-world implementation and impact of this program over 5 years.
Malaria is a major global health problem. The protein AMA1 plays a key role in the invasion of host cells by malaria parasites, and agents that inhibit this interaction prevent host cell invasion and thus represent leads for the development of anti-malarial drugs. We have identified a number of chemical scaffolds that target a key site on AMA1. In this project we will optimize these leads to generate potent ligands for this site and evaluate the efficacy of these ligands as anti-malarial agents.
Sitting Less And Moving More: Population Health Research To Understand And Influence Sedentary Behaviour

Funding Amount

Summary
The majority of Australian adults spend most of their waking hours sitting: at home, at work, and in their cars; most do not participate in exercise or sport. This leads to weight gain and to diseases of inactivity (particularly diabetes, heart disease, cancer and depression). New research will measure sitting time and the physical activity in people's daily lives, what factors encourage inactivity, and how to increase activity levels, especially among the ageing 'baby boomer' population.
