This application will investigate the potential for nanomaterials to have adverse effects on human health and to formulate approaches to screen nanomaterials for potential health risks, particularly those with a high likelihood for human exposure in Australia. Understanding how existing nanomaterials interact with biological systems will help determine the risk of adverse effects in the human population and identify those nanoparticles with little or no risk.
Synthesis, Biological Interactions and Toxicity Studies of Precisely Engineered Nanoparticles. The proposed benefits of nanotechnology for industries from material sciences, to bioengineering, energy and the environment are currently driving unprecedented growth in this technology world-wide. Some of these benefits are borne out of the unique properties that different nanoparticles exhibit. However, if nanomaterials pose a threat to the health and well-being of the community, then their risks ....Synthesis, Biological Interactions and Toxicity Studies of Precisely Engineered Nanoparticles. The proposed benefits of nanotechnology for industries from material sciences, to bioengineering, energy and the environment are currently driving unprecedented growth in this technology world-wide. Some of these benefits are borne out of the unique properties that different nanoparticles exhibit. However, if nanomaterials pose a threat to the health and well-being of the community, then their risks may outweigh their benefits. This project will identify those characteristics of nanoparticles that can lead to adverse effects and therefore pose a danger to the general community. By defining these characteristics, appropriate changes in nanomaterial production can be considered by industry to minimise these dangers.Read moreRead less
Blocking Paths To Suicide: A Data Linkage Program To Identify Modifiable Risk Factors For Self-poisoning And Suicide In Australia
Funder
National Health and Medical Research Council
Funding Amount
$501,205.00
Summary
This research examines the relationship between medicines use and suicide. Some medicines may be more toxic than others and identification of these could allow for targeted restrictions. In addition, medication use practices may influence self-harm and suicide. This research will identify patterns (e.g. non-adherence prior to death, incorrect doses) to pinpoint beneficial or harmful practices. This will improve outcomes and help guide suicide prevention through targeted legislation and policy.

Metals in Medicine. Metal-based drugs account for several billion dollars of pharmaceutical sales worldwide, but proportionally much less research and development has focussed on this area than organic drugs. Australia has played a pivotal role in the early development of metal-based pharmaceuticals, which remains a research strength.

Australia has played a pivotal role in the early development of metal-based pharmaceuticals, which remains a research strength. The dual aims of the initiative are to provide a network for a vibrant industry based around metals in medicine and to improve the health of Australians. The initiative will foster national and international cross-disciplinary collaborations to address the impediments holding back Australia's potential to take full advantage of our research strength in metals in medicine.Read moreRead less
Metal-Based Anti-inflammatory Drugs with High Efficacy and Low Side-Effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have widespread human and veterinary applications for the treatment of arthritis and other inflammatory diseases, but their utility is limited by often severe gastrointestinal, renal and cardiac side-effects. The recently heralded COX-2 inhibitors have not lived up to their expectations in terms of efficacy and side-effects, therefore, there is a need to develop new potent ....Metal-Based Anti-inflammatory Drugs with High Efficacy and Low Side-Effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have widespread human and veterinary applications for the treatment of arthritis and other inflammatory diseases, but their utility is limited by often severe gastrointestinal, renal and cardiac side-effects. The recently heralded COX-2 inhibitors have not lived up to their expectations in terms of efficacy and side-effects, therefore, there is a need to develop new potent, but safer, NSAIDs. This project is aimed at using the results from new lead compounds to design NSAIDs with much greater efficacy and much less side effects than those currently available.Read moreRead less
This Senior Principal Research Fellowship will support a program of translational research and leadership for the Therapeutics Research Centre that is based at the Translational Research Institute in Brisbane and The Basil Hetzel Institute in Adelaide and for future researchers/research leaders in clinical medicine. A key research focus will be in improving the safety and efficacy of products and nanosystems, especially after application to the skin and/or absorption into the body.

Summary
The sulfotransferase family of enzymes serve an important role in the metabolism of drugs and foreign chemicals. They also metabolise a range of chemicals that are normally present in the body such as hormones and substances that are involved in brain function (neurotransmitters). Observations from clinical studies suggest that differences in sulfotransferases activities may be a causal factor in the incidence of certain types of cancer and neurodegenerative diseases.

They also metabolise a range of chemicals that are normally present in the body such as hormones and substances that are involved in brain function (neurotransmitters). Observations from clinical studies suggest that differences in sulfotransferases activities may be a causal factor in the incidence of certain types of cancer and neurodegenerative diseases. Recent advances in understanding the molecular biology of these enzymes have shown us that multiple forms of sulfotransferase existed within the body. In this area my laboratory has been at the forefront of the cloning and characterisation of these enzymes. Indeed, we were the first laboratory to clone the major human sulfotransferase (SULT1A3) responsible for the metabolism of brain neurotransmitters. We have also used new technology to determine the shape of this important enzyme. At the time of writing my laboratory has characterised a total seven human sulfotransferases but unlike SULT1A3, our knowledge of the functional significance of the other six sulfotransferase is poorly understood. Further, our knowledge of what regulates the amount of sulfotransferase in different tissues is practically nonexistent. The thrust of this project is to extend our studies on the physiological function of these enzymes and also through the use of molecular biology techniques understand what controls the level of their expression in different human tissues. This knowledge will provide a basis for understanding the role of sulfotransferases play in drug and chemical metabolism. It will also aid our understanding of their role in hormone and neurotransmitter metabolism and help determine whether they are involved in such diseases as cancer and neurodegenerative diseases.Read moreRead less

Summary
The recent emergence of super bug bacterial strains has posed a situation where infections can not be treated. This health problem is growing rapidly with the spread of the resistant bacteria. This proposal intends to develop some of our designed anti-bacterial drugs to the point where they may be incorporated into mass clinical trials. A successful result will yield both a new antibiotic as well as an antibiotic to treat the super bugs.
