Evolution of a protein fold from toxin to physiological regulator: an endogenous potassium channel blocker in humans. A potassium channel blocking peptide employed by sea anemones as a toxic component of their venom is also found in proteins from a number of higher organisms, including man. In most of these proteins the function of this toxin domain is unknown. This project aims to define the structure and function of this domain in a human protein, matrix metalloprotease 23, which has possible ....Evolution of a protein fold from toxin to physiological regulator: an endogenous potassium channel blocker in humans. A potassium channel blocking peptide employed by sea anemones as a toxic component of their venom is also found in proteins from a number of higher organisms, including man. In most of these proteins the function of this toxin domain is unknown. This project aims to define the structure and function of this domain in a human protein, matrix metalloprotease 23, which has possible roles in prostate and other cancers. Our results will not only be of interest in tracing the structural and functional evolution of this toxin domain but will also provide valuable clues to its role in both the normal physiological function of matrix metalloprotease 23, as well as its potential pathological role in cancer.Read moreRead less
Local responses to the threat of HIV/AIDS in the logging concessions in the Western Province, PNG. This research takes place in the logging concessions of the Western Province of PNG - a province that borders Australia. Our project will investigate some factors influencing people's sexual behaviour in the logging concessions. Because of their capacity to attract migrant labour these logging concessions are potential 'hot-spots' for the transmission of HIV/AIDS throughout PNG and towards Australi ....Local responses to the threat of HIV/AIDS in the logging concessions in the Western Province, PNG. This research takes place in the logging concessions of the Western Province of PNG - a province that borders Australia. Our project will investigate some factors influencing people's sexual behaviour in the logging concessions. Because of their capacity to attract migrant labour these logging concessions are potential 'hot-spots' for the transmission of HIV/AIDS throughout PNG and towards Australia. From our findings we will develop a community based risk-reduction intervention strategy that will help slow the spread of infections into the Western Province and Australia.Read moreRead less

Developing a Hemodynamic Model for Improving Clinical Treatment of Vascular Diseases. Stroke caused by vascular diseases is the second greatest single killer, which is taking away thousands of lives and costing billions every year in Australia. Improving the existing clinical treatments of these diseases is thus of utmost urgency. This project is targeted to developing a reliable Hemodynamic model through comprehensive experimental validation approach. It will not only foster a more in-depth res ....Developing a Hemodynamic Model for Improving Clinical Treatment of Vascular Diseases. Stroke caused by vascular diseases is the second greatest single killer, which is taking away thousands of lives and costing billions every year in Australia. Improving the existing clinical treatments of these diseases is thus of utmost urgency. This project is targeted to developing a reliable Hemodynamic model through comprehensive experimental validation approach. It will not only foster a more in-depth research of vascular diseases but also provide a virtual forecasting tool for physicians or surgeons to develop guidance on diagnosis and therapeutic planning of clinical treatment, which brings great socio-economic benefit to the health of the Australian community.Read moreRead less
Elucidating the neurobiological basis for developmental stuttering using modern brain imaging techniques. We plan to untilise brain imaging techniques to examine the neurological underpinnings of stuttering. We aim to develop new tools for functional magnetic resonance imaging (fMRI) to examine the patterns of brain activation in the motor, speech and language areas, specifically for use in children who stutter. We aim to answer the question of whether stuttering is a motor-speech or a language ....Elucidating the neurobiological basis for developmental stuttering using modern brain imaging techniques. We plan to untilise brain imaging techniques to examine the neurological underpinnings of stuttering. We aim to develop new tools for functional magnetic resonance imaging (fMRI) to examine the patterns of brain activation in the motor, speech and language areas, specifically for use in children who stutter. We aim to answer the question of whether stuttering is a motor-speech or a language disorder and to establish whether variations in the speech and language regions of the brain found in adult stuttering research are also present in children who stutter, and to explore the possibility that different variations in brain activation and/or morphology may predict persistence and recovery.

Genetics of longevity and the delay of post-reproductive senescence. Ageing of the population in the coming decades will cause an increasing health care burden. Diseases of ageing such as Alzheimer's, heart disease, Parkinson's and a range of cancers, as well as impairments of ageing such as reduced mobility and cognitive ability are all caused or exacerbated by oxidative stress. With some exceptions, current medical practices focus on surgical repair or drug therapy to alleviate symptoms of ag ....Genetics of longevity and the delay of post-reproductive senescence. Ageing of the population in the coming decades will cause an increasing health care burden. Diseases of ageing such as Alzheimer's, heart disease, Parkinson's and a range of cancers, as well as impairments of ageing such as reduced mobility and cognitive ability are all caused or exacerbated by oxidative stress. With some exceptions, current medical practices focus on surgical repair or drug therapy to alleviate symptoms of ageing rather than addressing the physiological causes of ageing itself. Our project will provide understanding of natural systems that prevent age-related senescence due to oxidative stress. The goal is to identify novel and natural ways to maximise the fitness, well-being and self-sufficiency of people as they age.Read moreRead less
