Summary
This project will use a panel of Zinquin-derived Zn fluorophores developed in our laboratory, as well as probes for the mammalian family of vesicular ZnT transporters, to carry out a study of the normal physiology of Zn in the respiratory system and potential abnormalities of this in patients with chronic inflammatory respiratory disease (asthma, COPD, chronic smoking).

Chronic inflammatory diseases of the respiratory tract affect a significant proportion of the Australian community. For example, asthma affects 12% of adults and amongst these, 15% waken weekly or more often with their asthma while 6% are hospitalized annually. There is a need to understand the basic mechanisms underlying these diseases so that new strategies can be developed to modify bronchocondtriction and inflammation. The project will provide new knowledge concerning the physiology of Zn in the respiratory epithelium and interactions between Zn deficiency and oxidants on injury in the respiratory tract. The usefulness of easily accessible nasal epithelial cells as a measure of Zn and Zn transporter levels deeper in the respiratory tract will be assessed. The project encompasses a number of fields and utilizes in vitro cellular and animal models, as well as tissues from human subjects.Read moreRead less
Understanding and preventing gun violence: A qualitative study. Gun violence causes significant harm across Australian communities. Excluding sexual assault, firearms feature in nearly one in 10 violent crimes. The annual costs of gun violence run into tens of millions of dollars. This project aims to make an original qualitative contribution to understanding and preventing gun violence in three contexts: drug dealing/trafficking, other organised crime activity, and armed robbery.

Excluding sexual assault, firearms feature in nearly one in 10 violent crimes. The annual costs of gun violence run into tens of millions of dollars. This project aims to make an original qualitative contribution to understanding and preventing gun violence in three contexts: drug dealing/trafficking, other organised crime activity, and armed robbery. The proposed research would be the first study nationally - and one of the very few internationally - to interview convicted gun crime users about the acquisition and use of firearms in criminal life. Project results are expected to have direct implications for reducing the impact of gun violence in Australia.Read moreRead less

Summary
Many diseases that effect the respiratory system have their primary effect on the lungs and airway themselves but in some conditions, such as obstructive sleep apnea (OSA) and asthma, increased breathing load can induce periods of low blood oxygen which could further contribute to morbidity in these diseases.

OSA is a disorder associated with snoring. Patients experience periods of sleep fragmentation and oxygen deprivation due to obstruction of the floppy portion of the upper airway (pharynx) during sleep. It affects 4% of men and 2% of women and causes excessive daytime sleepiness leading to increased risk of accidents, high blood pressure and premature cardiovascular disease. Asthma produces airway inflamation and narrowing and affects a wide range of people. Both OSA and asthma are associated with episodes of impaired breathing and reduced levels of oxygen in the blood. Low levels of oxygen in the blood (hypoxia) is well known to impair functioning of the central nervous system. We have recently found that hypoxia blunts sensations of increased breathing load in healthy people and in asthmatics. Hypoxia might therefore contribute to worsening of attacks in these diseases. This study aims to investigate how changes in blood oxygen levels affect brain processing of respiratory signals, how this translates to perception of sensations and the physiological adaptations that people make to cope with increased breathing load. We will also investigate whether the inhibitory effects of hypoxia on central nervous system function extend to other vital protective respiratory reflexes such as cough, awakening from sleep to increased breathing load and upper airway reflexes that are important for maintaining an open airway.Read moreRead less

Summary
Alcohol is a major cause of death, injury and illness in Australia accounting for over 3,000 deaths and over 72,000 hospital admissions each year. Excessive drinking is estimated to cost the Australian community $7,560 million each year, representing 22% of all drug-related harm. Alcohol is a significant contributor to the occurrence of violence and crime.

Excessive drinking is estimated to cost the Australian community $7,560 million each year, representing 22% of all drug-related harm. Alcohol is a significant contributor to the occurrence of violence and crime. It is estimated that up to 70% of incidents attended by the police, and 77% of street offences such as assaults and malicious damage to property, are alcohol-related. It is also estimated that 70% to 80% of night-time single-vehicle accidents are alcohol-related. A large proportion of assaults, offensive behaviour, malicious damage to property and drink driving occur following excessive drinking at licensed premises such as hotels and registered clubs. The risk of harm arising from the consumption of alcohol on licensed premises can be reduced by modifying such factors as service of alcohol to intoxicated patrons, service-supply of alcohol to underage patrons, management practices (eg. late closing) and environmental factors (eg. poor lighting). Auditing of licensed premises is an approach currently used by authorities to ensure compliance with licensing requirements. However, such audits do not focus on harm reduction and do not incorporate best practice audit and behaviour change features. No controlled studies have reported the effectiveness of such an audit approach in reducing the risk of violence and crime emanating from hotels and registered clubs. The proposed study aims to assess the effectiveness of a Responsible Hospitality Audit and feedback intervention in reducing service to intoxicated and underage patrons, and in reducing assaults-malicious damage to property following alcohol consumption on licensed premises. The outcomes of this study will be improved responsible service of alcohol actions and reduced alcohol-related crime associated with premises.Read moreRead less

The research focuses on the group of offenders who, as a cohort, annually commit the most crime within Australia. The production of longitudinal qualitative data about individual experiences of secure care, release, and imprisonment, will provide a foundation for empirically driven policies and debates in the area of youth crime and incarceration for each state and territory. Accordingly, the community will benefit through the generation of new possibilities for intervening in cycles of persistent offending and repeat custodial sentences. This has major social, cultural and economic implications. Read moreRead less
