Summary
Very low energy diets (VLED) are increasingly used to treat obesity. Of concern is the fact that VLED induce adaptive responses that can inhibit loss of, and promote regain of, abdominal fat while decreasing lean body mass, muscle strength and bone density. This project will therefore determine whether VLEDs could have negative effects on body composition that increase the risk of metabolic disease, sarcopenia or osteoporosis, and if so, what mechanisms are involved.
An In Depth Analysis Of Clinical And Virological Outcomes Of 2 Strategies For The Antiretroviral Salvage Of First-line Regimen Virological Failure For HIV-1 Infection Tested In An Australian-led Randomised, International, Multi-centre Clinical Trial

Summary
The recently completed Australian-led SECOND-LINE trial is the first high quality study to provide reliable evidence for policy recommendations for the composition of anti-HIV drug cocktails after standard initial treatment has failed. This award will support the researcher in further refining our understanding of how to manage second-line therapy including proposals to test the use of low-cost technologies for application in resource-limited settings where the majority of people with HIV live.

Summary
Osteoporosis is a condition characterised by excessive bone loss and impaired bone quality, which ultimately results in fracture with minimal trauma. Osteoporosis affects 27% of women and 11% of men aged 60 years or above in the community, and costs Australia around $7 billion each year. Individuals with low bone mineral density (BMD) have a significantly higher risk of fracture than those with normal BMD. In the long-term (14-year) Dubbo Osteoporosis Epidemiology Study, more than half of indivi ....Osteoporosis is a condition characterised by excessive bone loss and impaired bone quality, which ultimately results in fracture with minimal trauma. Osteoporosis affects 27% of women and 11% of men aged 60 years or above in the community, and costs Australia around $7 billion each year. Individuals with low bone mineral density (BMD) have a significantly higher risk of fracture than those with normal BMD. In the long-term (14-year) Dubbo Osteoporosis Epidemiology Study, more than half of individuals with osteoporosis (e.g., low BMD) did not sustain a fracture, while approximately 60% of fracture cases had BMD above the high risk levels. Thus, BMD alone is not a good discriminant of fracture versus non-fracture cases. It is widely known that the liability to fracture is determined in part by genes. Previous studies, including from our group, have suggested a number of candidate genes that are associated with fracture risk. The fundamental issue that this study is concerned is that how and whether genetic markers could be used to facilitate case finding. It is proposed that common variations of certain genes are associated with fracture risk independent of BMD. That is, they can identify individuals at relatively high and low fracture risk after stratification for BMD. Hence, some markers may identify those individuals likely (and unlikely) to fracture even with low (osteoporotic) BMD. Similarly, some, possibly the same, markers may identify individuals at high risk of fracture despite relatively good (ie non-osteoporotic) BMD. It is further proposed that no single gene will achieve this outcome, but rather a small set of such gene polymorphisms will provide clinically useful risk information. This effect is entirely analogous to the use of clinical risk indicators (eg, age, weight, sex, family history, etc) to assess the risk of future fracture.Read moreRead less
Myeloma Plasma Cell Dormancy - 'Eradicating The Sleeping Giant'

Summary
Multiple myeloma is a fatal cancer that develops in the skeleton. Current therapies are initially effective, but patients develop resistance and the disease returns. This makes the search for drugs to overcome resistance a priority. Myeloma cells can hide in bone in a dormant state where they are insensitive to chemotherapy. We have identified new drug targets in dormant cells. We are investigating whether these new targets can be used eradicate myeloma cells and cure the disease.
Stress During Pregnancy And The Developmental Origins Of Renal Disease In Aboriginal Australians

Funding Amount

Summary
There is an epidemic of renal failure in Aboriginal people who also have high rates of premature birth of small babies. This project aims to understand the causes of kidney failure in Aboriginal people through testing if stress during pregnancy leads to the birth of preterm, small babies with small poorly formed kidneys that lead to kidney failure in later life. The effect of stressors impacting on pregnant women including infections, exposure to smoking and social stressors will be examined.

Topological phonons in solids.

This project aims to create a complete list of possible topological phonons in time-reversal-invariant systems via symmetry analysis, to determine ideal topological phononic materials, and to study topological phonon-related properties and possible applications. The significant outcomes of this project will be the generation of new knowledge that will help conclude the search for novel topological phonons and the prediction of novel topological phononic materials based on the complete classification list of topological phonons. The outcomes of this project should unlock the physics of the exotic topological phonons and lay a solid foundation for applying topological phononic materials based on their unprecedented properties.Read moreRead less
This study aims to elucidate central pathways which can be manipulated to drive the storage of excess energy away from fat and instead directing it into the production of bone mass. Having identified leptin-responsive NPY neurons as important in the control of energy partitioning, we will focus on manipulating these neurons in the hypothalamus using innovative technology to alter body composition. This research has the potential to result in novel treatments for obesity and osteoporosis.
