DEVELOPMENT OF A NOVEL BIOMATERIAL FOR BONE TISSUE ENGINEERING. Tissue engineering of bone is emerging as a viable therapy for treating large defects in load-bearing bone. We wish to develop methods for combining novel heparan sulphate molecules (known to deliver growth factors to cell surfaces and thereby cause changes in bone cell phenotype) with load-bearing, macro-porous, biodegradable mineral/polymer biomaterials. Through the study of release profiles, protein adsorption and cell responses ....DEVELOPMENT OF A NOVEL BIOMATERIAL FOR BONE TISSUE ENGINEERING.

This will be Australia's first dedicated five-dimensional multiphoton-microscopy platform, allowing observation of dynamic structures across different length and time scales under controlled temperatures, followed by high-resolution electron microscopy studies on the same samples. This platform will provide a unique characterisation tool to Australia's top-flight investigators, and so contribute to the nation's research priorities. It will enable: fundamental studies of cancer, neural diseases and immune disorders; the development of frontier technologies, such as smart nanomaterials, biosensors and targeted drug delivery; and applied research to help plants and soils adapt to climate variability, and to increase sustainable use of water.Read moreRead less
Free Radicals in Chemistry and Biology: A Computational Quantum Chemistry Investigation. This proposal aims to carry out state-of-the-art chemistry research using computers rather than traditional laboratory techniques.

This proposal aims to carry out state-of-the-art chemistry research using computers rather than traditional laboratory techniques. Free radicals, which have widespread importance in the multibillion dollar polymer and health industries, form the centrepiece of the proposal. These are highly reactive substances that are difficult to study by conventional experimental techniques but ideal to study using computers. The increased understanding of free radicals that will stem from this research may help in dealing with ageing, and afflictions such as hardening of the arteries and vitamin B12 deficiency. It will also result in the training at the highest level of new generations of chemists in this exciting field of "chemistry with computers".Read moreRead less

We will use state-of-the-art computer calculations to investigate chemical structures, stabilities and reactions, particularly for free radicals. Radicals are of great importance in chemistry, biology and polymer science, but are difficult to study experimentally. We will use the computer calculations to determine how to make radicals more stable, how they react to produce polymers, how they cause damage to proteins, and how they are involved in helping vitamin B12 make reactions go faster. We will create new methodologies in order to reliably achieve these goals.Read moreRead less

Streamlining the dynamin epilepsy drug pipeline. Epilepsy affects up to one percent of Australia's population, yet one in three fail to respond to current medications. Our results will greatly impact on development of future epilepsy therapy. Identification of a new target for epileptic will allow better drug design to improve the potency of our lead drugs. This holds hope that new generation drugs will be more effective. The drugs are predicted to have fewer complications and side-effects. Th ....Streamlining the dynamin epilepsy drug pipeline.

Identification of a new target for epileptic will allow better drug design to improve the potency of our lead drugs. This holds hope that new generation drugs will be more effective. The drugs are predicted to have fewer complications and side-effects. The outcome has the potential to vastly improve prospects for up to 200,000 Australians. Intellectual property (IP) retained in Australia will generate future biotechnology industry. The novel chemical biological approaches will facilitate training of future generations of Australian scientists.Read moreRead less

Summary
A New Generation Biosensor and Fluorescence Facility for Proteomics. The complete DNA sequence (the genome) is now known for many organisms and advances are being made to identify the complement of messenger RNA (the transcriptome) and the resultant collection of proteins (the proteome). The genome is largely fixed while the transcriptome and proteome differ between cell types in an organism and constantly vary to adapt the cell to changing conditions. The mediators of these variations are prote ....A New Generation Biosensor and Fluorescence Facility for Proteomics. The complete DNA sequence (the genome) is now known for many organisms and advances are being made to identify the complement of messenger RNA (the transcriptome) and the resultant collection of proteins (the proteome). The genome is largely fixed while the transcriptome and proteome differ between cell types in an organism and constantly vary to adapt the cell to changing conditions. The mediators of these variations are proteins, interacting with each other and with signal molecules. The next frontier in molecular biology is to identify and quantify these protein interactions. Our two institutions have a very large cohort of biologists whose research on proteins would be greatly facilitated by the Biacore 3000 and the ISS K2.Read moreRead less

Defects in mitochondria, the energy producing compartments within cells, lead to severe neurodegenerative diseases and contribute to the development of cancer. Treatment for such diseases caused by mutations in mitochondrial DNA remains unsatisfactory and mostly confined to supportive measures. The identification of proteins that regulate gene expression within mitochondria provides an unexplored resource of potential disease modulators and drug targets. This research will lead to new strategies in the design of improved anticancer drugs, which is an important Australian research priority that will promote and maintain good health, and provide potential commercial outcomes.Read moreRead less
