Novel Antimicrobial Biomaterials. There is a clear need for new materials that repel bacteria. Infections associated with biomaterials incur a high cost in terms of human health and well being, but such infections also increase the burden on the health care system by extending hospital stays and significantly elevating costs. The cost of a catheter-related blood stream infection is around $50,000 for patients in intensive care units. If all medical devices are considered, the cost of related inf ....Novel Antimicrobial Biomaterials. There is a clear need for new materials that repel bacteria. Infections associated with biomaterials incur a high cost in terms of human health and well being, but such infections also increase the burden on the health care system by extending hospital stays and significantly elevating costs. The cost of a catheter-related blood stream infection is around $50,000 for patients in intensive care units. If all medical devices are considered, the cost of related infections is then approximately $20 billion. The technology proposed here has the potential to reduce biomaterial related infection rates, improve health care and reduce health care costs. Read moreRead less

microRNAs: discovery and analysis in mouse development. MicroRNAs (miRNAs) are a new class of regulatory molecule, recently found to be abundant and strongly conserved in several eukaryotic species, encoded by genes that are transcribed into short stem-loop structures and then processed into ~22nt single-stranded RNAs by the RNAi pathway. We have cloned novel miRNAs, and obtained the first evidence for regulation of a miRNA in a mammal. We propose to continue cloning novel miRNAs by the tried m ....microRNAs: discovery and analysis in mouse development. MicroRNAs (miRNAs) are a new class of regulatory molecule, recently found to be abundant and strongly conserved in several eukaryotic species, encoded by genes that are transcribed into short stem-loop structures and then processed into ~22nt single-stranded RNAs by the RNAi pathway. We have cloned novel miRNAs, and obtained the first evidence for regulation of a miRNA in a mammal. We propose to continue cloning novel miRNAs by the tried method, and to explore bioinformatics-based methods of identification. We will also study the expression of miRNAs in mouse embryos at successive stages, and develop a microarray assay for miRNA expression.Read moreRead less

The smart use of information to improve, promote and maintain good healthcare is a critical mission for our country. Cancer is a serious problem in Australian society and 1 in 4 individuals will be affected by it in their lifetime.

The smart use of information to improve, promote and maintain good healthcare is a critical mission for our country. Cancer is a serious problem in Australian society and 1 in 4 individuals will be affected by it in their lifetime. Our research is focussed on two types of cancer - lung cancer and the lymphomas - and it will use IT in a novel way to extract important information from a very large biomedical data repository. We hope that it will improve personalised diagnosis and treatment in these cancers and provide new information on how some cancers spread and resist our usual treatments. We think our techniques will contribute to other research areas such as astronomy, agriculture, water/energy resources, and security.Read moreRead less
Synthetic Molybdenum Enzymes. This project aims to produce synthetic molybdenum (Mo) enzymes, small molecules that share structural and functional attributes with the crucially important molybdopterin?Mo enzymes. These ubiquitous enzymes are essential for plant and animal health, natural cycles involving carbon, nitrogen and sulfur, and global climate control and atmospheric albedo (reflectance); consequently, they impact heavily on commerce, the environment and society.

This project aims to produce synthetic molybdenum (Mo) enzymes, small molecules that share structural and functional attributes with the crucially important molybdopterin?Mo enzymes. These ubiquitous enzymes are essential for plant and animal health, natural cycles involving carbon, nitrogen and sulfur, and global climate control and atmospheric albedo (reflectance); consequently, they impact heavily on commerce, the environment and society. The study will provide urgently needed insights into the fundamental Mo?sulfur chemistry of the enzyme active sites and inform efforts to reduce the negative impacts of enzyme dysfunction and the design of new commercial catalysts.Read moreRead less

Muscle fibre excitability and calcium regulation in skeletal muscle of amphibians and mammals. The fundamental role of skeletal muscle is posture and movement. Essential for this is a specialised cell structure and a complex regulation of function. This project will define key aspects of muscle structure and functional regulation crucial to developing targets for improving function under stressed states such as fatigue, disease and age.
