Summary
Our team has recently developed a synchrotron technology with a startling capacity for dynamic functional imaging that can act as a sensitive regional indicator of lung disease. We will demonstrate that this technology can be translated from the synchrotron to the lab and eventually the clinic. We will provide proof of this concept by the application of this technology to emphysema, asthma, lung cancer, cystic fibrosis lung disease and neonatal resuscitation.
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.

Summary
Primary hip replacement is a successful intervention for hip disease, but 10-15% of hip prostheses fail and require revision surgery within 10-15 years. At the time of revision, significant bone loss around the failed prosthesis is not uncommon. A bone reconstruction procedure, called impaction grafting, where donor bone is minced and placed in the areas of deficient bone before implanting the new prosthesis, has shown to give good results at more than ten years in some centres. A high incidence ....Primary hip replacement is a successful intervention for hip disease, but 10-15% of hip prostheses fail and require revision surgery within 10-15 years. At the time of revision, significant bone loss around the failed prosthesis is not uncommon. A bone reconstruction procedure, called impaction grafting, where donor bone is minced and placed in the areas of deficient bone before implanting the new prosthesis, has shown to give good results at more than ten years in some centres. A high incidence of early complications of this procedure have included loss of fixation within the bone. Fracture of the bone around prostheses has also reported in some centres. These events require more surgery, putting the patient at higher risk greater complications and longer rehabilitations. Recent improvements in surgical technique and donor bone preparation have improved results. A current debate questions whether the dose of irradiation can be reduced from 25 kGy, while maintaining sterility of allografts. The risk of bacterial contamination in allografts is low, and irradiation reduces the mechanical strength of the graft, contributing to complications when irradiated bone is used. The benefits of decontaminating the bone may be outweighed by the higher risk for failure due to poor bone quality and resulting prosthesis instability. We will use ISO standards to test the validity of radiation dose for sterilising bone ex vivo. In the absence of controlled human studies, our aim is also to compare the results of impaction grafting with non-irradiated bone versus bone irradiated at current doses used by Australian bone banks, and lower doses indicated by ex vivo testing. We will use a large animal model of revision hip replacement, with precise measures of prosthesis stability. The results of this study will guide clinical decisions regarding the efficacy of current bone graft preparation procedures and the use of irradiated bone in human hip replacement surgery.Read moreRead less
Novel Methods For Promoting Organ Development And Growth

Summary
A revolutionary new therapy for treatment of growth restricted fetuses and premature babies is being developed through the administration of Colony Stimulating Factor (CSF-1). We have evidence that CSF-1 therapy can promote kidneys and lungs to continue development and maturation after birth. This exciting new finding allows for the application of CSF-1 therapy for both the treatment of premature babies and unborn babies with kidney defects.
The Role Of Adipokines In Modulation Of Gastric Vagal Afferent Satiety Signals

Summary
When we feel full after a meal it is the result of a variety of different nerve signals from the gut in response to distension of the stomach and specific nutrients. These signals are disordered in obesity and may be influenced by factors released from fat stores in the body. The aim of this project is to determine how these factors interact with gastric nerve satiety signals and thus identify targets for the pharmacological treatment of obesity.
Ecology, morphology and the diversification of Australian lizards. This project aims to determine the factors driving the spectacular radiation of lizards in Australia. To date, most investigations of lizard anatomy have focused exclusively on external characteristics. This project will examine the underlying internal anatomy to investigate whether morphological innovation is associated with enhanced rates of ecological, life-history and species diversification.

This project aims to determine the factors driving the spectacular radiation of lizards in Australia. To date, most investigations of lizard anatomy have focused exclusively on external characteristics. This project will examine the underlying internal anatomy to investigate whether morphological innovation is associated with enhanced rates of ecological, life-history and species diversification. The project expects to shed light on the evolution of Australia’s most diverse vertebrate lineage, and provide comparative data with which to interpret the lizard fossil record in Australia, and the range declines and relative extinction risks of native lizard species.Read moreRead less
Identification Of Genes For X-linked Mental Retardation.

$675,228.00
Summary
We propose to identify novel heritable causes of intellectual disability using 22 large and well-characterised families from Australia. In these families we have refined the location of the genetic defect to the chromosome X and excluded the contribution of all so far known genes. We will achieve this using the technology of massive parallel sequencing. At the completion of the project we will have identified novel causes of intellectual disability and devised tests to identify them.

Summary
CVD is the primary contributor to life expectancy differentials between Indigenous and non-Indigenous Australians. Even when cardioprotective therapies are optimally used, residual risk of adverse events is often observed. Testing of additional therapies that improve survival among Indigenous people with CVD is required. Omega 3 fatty acids can improve multiple atherogenic pathways. This trial will assess the impact of Omega 3 in Aboriginal patients with CVD.

Summary
Proper functioning of the nonsense mediated mRNA decay (NMD or 'mRNA police') is crucial for any cell to ensure normal development and function. When NMD is compromised the outcome is learning and memory problems, autism or schizophrenia. Under this project we study malfunctioning NMD using stem and neuronal cells derived from patients' skin cells. Some of the affected genes might be considered for therapeutic interventions.

Synchrotron X-ray Assessment Of Airway Surface Physiology For Cystic Fibrosis

Funding Amount
$778,228.00
Summary
We seek a cure or long-lasting therapy for the fatal airway disease in cystic fibrosis. Disease is caused by a shallow and dehydrated airway surface liquid (ASL), allowing bacteria to infect the lung. We can introduce a corrective gene into mouse airways where it can be effective for over 1 yr, but no fast, accurate and non-invasive measurement exists to test if treatments are successful. We will develop methods using synchrotron light to directly measure ASL depth changes in live mouse airways.
