Summary
Demyelinating diseases of the central nervous system such as multiple sclerosis have a lifelong impact and devastating impact on quality of life. We have identified that a growth factor, brain derived neurotrophic factor (BDNF), plays an important role in promoting myelination during development. We will investigate the potential of translating these findings into effective clinical treatment, by characterising the efficacy of BDNF in promoting CNS remyelination after a demyelinating insult.
Investigating the functional interaction between vasopressin and angiotensin receptors. Kidney disease resulting from diabetes is a major health issue for Australians, and indigenous Australians in particular. This project aims to enable improved therapies to be developed, as well as better inform doctors regarding the use of potential combinations of existing pharmaceuticals to treat this condition.
Sustainable copper metallurgy and recycling – saving energy and resources. This project aims to develop new, powerful and sophisticated, computer-based models that can reliably predict the results of chemical reactions in complex, high temperature metal production processes. This project expects to use these models, initially applied to copper smelting systems, to enable the improved recycling of other valuable metals. These models should be able to be applied to a wide range of technologies use ....Sustainable copper metallurgy and recycling – saving energy and resources. This project aims to develop new, powerful and sophisticated, computer-based models that can reliably predict the results of chemical reactions in complex, high temperature metal production processes. This project expects to use these models, initially applied to copper smelting systems, to enable the improved recycling of other valuable metals. These models should be able to be applied to a wide range of technologies used in the metallurgical industry as most of the world’s metals are produced by these pyrometallurgical processes. This should provide significant benefits such as substantial improvements in productivity and process efficiencies, whilst at the same time delivering energy savings and improved use of valuable metal resources.Read moreRead less
Fish venom as a model system for the molecular evolution of defensive toxins. The key aim of this study is to undertake a thorough investigation of venoms found in distinct fish lineages, including enigmatic species such as venomous and medically important species such as the stonefish. By characterising the biodiversity of toxins found in the venoms of different fish, the evolutionary history of venom in this major vertebrate lineage can be revealed. The investigations proposed here will also d ....Fish venom as a model system for the molecular evolution of defensive toxins. The key aim of this study is to undertake a thorough investigation of venoms found in distinct fish lineages, including enigmatic species such as venomous and medically important species such as the stonefish. By characterising the biodiversity of toxins found in the venoms of different fish, the evolutionary history of venom in this major vertebrate lineage can be revealed. The investigations proposed here will also determine the functional activities of different venoms and their components. This will not only help the understanding of the medical consequences of the annual thousands of fish envenomings but also explore a largely unstudied resource for the discovery of new pharmacological diagnostics and therapeutics.Read moreRead less
Modelling The Effects Of Immunity On Influenza Transmission - Implications For Prevention And Vaccine Development

Summary
There is uncertainty about how many people can be infected by a single person with influenza at the start of an outbreak. Some data suggest that a single generation of transmission can infect 10-20 other people. With such a rate of growth (ie 10-20 fold every 3 days) the spread of an influenza outbreak is virtually unstoppable. Other data suggest that each person with influenza infects less than 2 other people on average. With such a lower rate of growth, control would be more feasible. Our proj ....There is uncertainty about how many people can be infected by a single person with influenza at the start of an outbreak. Some data suggest that a single generation of transmission can infect 10-20 other people. With such a rate of growth (ie 10-20 fold every 3 days) the spread of an influenza outbreak is virtually unstoppable. Other data suggest that each person with influenza infects less than 2 other people on average. With such a lower rate of growth, control would be more feasible. Our project will use data from historic and contemporary outbreaks of influenza and build mathematical models to explain the rate of growth of an influenza outbreak in terms of: 1. The proportion of people exposed to influenza who do not become ill (although there can be evidence of infection if careful studies are made). This proportion is about 33%. 2. The proportion of people who are protected from influenza by immunity, whether induced by vaccination or by past exposure to natural influenza infection (this can vary from 0% in isolated populations which have not seen influenza for many years up to 80 or 90% in urbanised populations that are exposed to influenza almost every season). 3. Different rates of contact between different people and groups of people - some may be exposed so often that their immunity is boosted regularly without them becoming severely ill; others, living in more isolated circumstances, may be rarely exposed, but when they are, they are more likely to become severely ill. 4. The effects of influenza vaccine in inducing protective immunity - it is well known that there is good protection if the vaccine is well matched to the circulating virus. 5. The effects of live virus infection in inducing (short-lived) protection against a wider range of influenza viruses. Our model results will be used to guide vaccine design and pandemic planning.Read moreRead less
Innovative thermodynamic process control - the key to sustainable metal use. Large amounts of electronic goods such as computers and mobile phones are discarded each year in Australia. They contain both valuable and toxic metals so dumping them as landfill is unacceptable. Australia has a smelting method which could be adapted to reprocess this waste to recover the valuable metals, returning them for reuse. It would also safely handle the toxics. This project will determine the appropriate s ....Innovative thermodynamic process control - the key to sustainable metal use. Large amounts of electronic goods such as computers and mobile phones are discarded each year in Australia. They contain both valuable and toxic metals so dumping them as landfill is unacceptable. Australia has a smelting method which could be adapted to reprocess this waste to recover the valuable metals, returning them for reuse. It would also safely handle the toxics. This project will determine the appropriate smelting strategies and control methods. As a result, transportation of toxic materials overseas will be eliminated, environmental hazards will be reduced and our sustainable use of metals will be increased.Read moreRead less
