Summary
Obstructive sleep apnoea (OSA) is a serious medical disorder with a high public health cost. OSA can be effectively treated but poor treatment compliance is a major clinical problem. As a consequence many OSA patients remain untreated, with significant implications for their long term health. New effective and safe therapies are needed. We believe that we will demonstrate a relatively straightforward, safe and effective surgical procedure for OSA after primary treatments fail. This will lead to ....Obstructive sleep apnoea (OSA) is a serious medical disorder with a high public health cost.

Airway Epithelial IAPs And Their Interaction With Zn Ions

Funding Amount
$260,779.00
Summary
The air we breathe contains a variety of harmful substances. Damage to the lining involves death of the ciliated cells that line the airways. We have shown that zinc protects these cells from premature death. This application focuses on a family of proteins called IAPs which bind zinc and regulate cell death in other tissues. This project focusses on how the IAPs and Zn may act together to mainitain healthy airways and how abnormalities of these may occur in people with asthma.
Revolutionising The Diagnosis And Monitoring Of CF Lung Disease

Summary
Cystic fibrosis (CF) lung disease starts early in childhood and relentlessly progresses, with early death a common outcome. There is currently no method capable of detecting very early disease onset nor directly assessing the effectiveness of putative treatments. This project will apply our globally unique X-ray imaging tools, which are capable of imaging lung function at any point across the entire lung, for the very early detection of CF and assessment of clinically applicable treatments.
Clarifying The Pathogenic Role Of Arousal-hyperventilation In Obstructive And Central Sleep Apnoea: Testing Fundamental Pathophysiological Mechanisms And A Strategic New Treatment

Funding Amount
$414,717.00
Summary
This project is designed to understand the mechanisms underpinning much more stable breathing during deep sleep in obstructive sleep apnoea (OSA). A newly developed analytical technique will be used to examine breathing effort changes across sleep, and interactions with respiratory-induced awakenings in OSA patients. In addition, a new treatment designed to stabilise breathing will be tested and refined towards a new treatment option for OSA and for central sleep apnoea.
Treating Insomnia Co-morbid With Obstructive Sleep Apnoea: A Randomized Controlled Clinical Effectiveness Trial.

Funding Amount
$600,869.00
Summary
Obstructive Sleep Apnoea (OSA) is a common but serious sleep disorder. Continuous positive airways pressure (CPAP) therapy can be very effective in treating OSA. We have found that many patients with OSA also suffer from insomnia, and this can make it hard for them to begin CPAP therapy and hard for them to stick to it. This trial will examine the effect of treating insomnia concurrently with CPAP, with the expectation that overall treatment outcomes will improve.

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 ....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
Small is beautiful: Did gene-rich regions of mammal chromosomes evolve from microchromosomes? Most birds and reptile genomes feature many tiny microchromosomes. These are not junk, as previously thought, but contain most of the genes. Mammals lack microchromosomes, but contain gene-rich regions with similar attributes. We suggest that microchromosomes originated by genome duplication, and evolved into the gene-rich regions of mammalian chromosomes. We will test this hypothesis by comparing seque ....Small is beautiful: Did gene-rich regions of mammal chromosomes evolve from microchromosomes? Most birds and reptile genomes feature many tiny microchromosomes. These are not junk, as previously thought, but contain most of the genes. Mammals lack microchromosomes, but contain gene-rich regions with similar attributes. We suggest that microchromosomes originated by genome duplication, and evolved into the gene-rich regions of mammalian chromosomes. We will test this hypothesis by comparing sequences and genes in microchromosomes of birds, reptiles and monotremes. This will clarify the origin and evolution of the ?microgenome?, establish its suitability as a model for vertebrate genome organisation, and demonstrate whether microchromosomes are the ancestors of the gene-rich regions of mammalian chromosomes.Read moreRead less
Identification Of The Conformation Dependant Targets Of Autoimmune Disease Linked Variation In Human Regulatory T Cells

Funding Amount
$1,001,815.00
Summary
Specialised immune cells called regulatory T cells act as the policemen of the immune system, preventing the immune system attacking itself, but still fighting infections. If these cells do not work properly, autoimmune diseases such as type 1 diabetes or IBD can arise, because of immune attack on normal body tissue by mistake. In order to explain how this goes wrong we need to carefully identify all of the gene interactions in these cells including interactions over long distances in the DNA.

Family-run farms are an integral part of rural Australia. Given the evolving global financial crisis and the expanding complexity of managing a family farm in Australia due to increasing competition from large incorporated holdings and overseas producers, a persisting drought, rising climate variability, and constraining carbon markets, one critical issue for the sustainability of family farms is their ability to access and manage successfully competitive sources of credit. This study examines the extent to which family farms are currently at a disadvantage, and what policies could be implemented to ensure their sustainability into the future via access to competitive lines of credit and appropriate financial management practices.Read moreRead less

Plant genomics has direct benefit to crop improvement, especially as focussed in the applicants' laboratories. Thus, the Australian agri-food sector will benefit substantially from the acceleration in plant functional genomics that will arise from the installation of the robotics equipment described in the current application, by both underpinning more applied research and also being used directly in crop improvement programs such as are based at the Waite Campus. The outputs will include crops with increased tolerance to biotic and abiotic stresses, a reduced dependence on chemical inputs such as fertilisers and improved food quality, with consequent benefits to the environment and human health and nutrition.Read moreRead less
