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
Natural Therapeutic Products from Shark Bile. Scymnol and its sulfate are natural therapeutic products from shark bile with highly potent anti-oxidant and liver-protective activities. The Industry Partner and Macrides have co-patented the synthesis of scymnol to avoid using scarce natural resources. However, unresolved problems in scale-up of production have prevented them from supplying the growing demands of cosmetic and health food companies. Our research group has recently developed a potent ....Natural Therapeutic Products from Shark Bile. Scymnol and its sulfate are natural therapeutic products from shark bile with highly potent anti-oxidant and liver-protective activities. The Industry Partner and Macrides have co-patented the synthesis of scymnol to avoid using scarce natural resources. However, unresolved problems in scale-up of production have prevented them from supplying the growing demands of cosmetic and health food companies. Our research group has recently developed a potential synthetic route for scymnol sulfate. The present project aims to develop a commercially-viable scale-up of this synthesis for manufacturing scymnol and scymnol sulfate to solve current supply problems; and to provide essential safety information for their appropriate use; and evaluate potential new therapeutic uses.Read moreRead less
The effect of dissolved organic matter on the toxicity and bioavailability of metals in tropical freshwater ecosystems. Mine waste materials in tropical Australia, including historical, current and future operations, represent one of the threats to the quality and biodiversity of tropical freshwater ecosystems. Dissolved organic carbon (DOC) is thought to influence metal toxicity. In order to adequately understand the risks of priority metals and metalloids from mining and other activities (eg. ....The effect of dissolved organic matter on the toxicity and bioavailability of metals in tropical freshwater ecosystems. Mine waste materials in tropical Australia, including historical, current and future operations, represent one of the threats to the quality and biodiversity of tropical freshwater ecosystems. Dissolved organic carbon (DOC) is thought to influence metal toxicity. In order to adequately understand the risks of priority metals and metalloids from mining and other activities (eg. urban development) to tropical freshwater ecosystems, it is essential that the role of DOC is quantified. The outcomes of this project will provide improved metal risk assessment methodologies; quantitative understanding of the relationship between DOC and the bioavailability and toxicity of key metals such arsenic, aluminium, cadmium, copper, uranium and zinc.Read moreRead less
Development of a risk assessment tool to minimise mixed metals toxicities from mine tailings. Research based on animal uptake from mine tailings is required to quantify comparative bioavailability of mixtures of metals to provide data for mine rehabilitation design during the planning stage. Such data also provides risk assessment in humans. The optimum balance is minimum environmental effects from the rehabilitated mine structure versus minimised cost through planning prior to project commencem ....Development of a risk assessment tool to minimise mixed metals toxicities from mine tailings. Research based on animal uptake from mine tailings is required to quantify comparative bioavailability of mixtures of metals to provide data for mine rehabilitation design during the planning stage. Such data also provides risk assessment in humans. The optimum balance is minimum environmental effects from the rehabilitated mine structure versus minimised cost through planning prior to project commencement. The significant cost of mining ore bodies, particularly by modern open cut methods, is the removal of rock and soil. The research on animal toxicity testings will provide a tool to more accurately detail mine rehabilitation and give quantitative indicators for closure.Read moreRead less
Micro- and nano-particulate delivery systems for chemical and biological weapons: physical characterisation and risk assessment. Inert solid powder has been used as a carrier for chemical and biologically-active agents to increase their effectiveness in a range of applications such as chemical weapons, pesticides and insecticides. The aim of this research is to determine the influence of the physical characteristics of particulate delivery systems on their ability to deliver potentially toxic s ....Micro- and nano-particulate delivery systems for chemical and biological weapons: physical characterisation and risk assessment. Inert solid powder has been used as a carrier for chemical and biologically-active agents to increase their effectiveness in a range of applications such as chemical weapons, pesticides and insecticides. The aim of this research is to determine the influence of the physical characteristics of particulate delivery systems on their ability to deliver potentially toxic substances to exposed skin and through protective clothing. This data will provide the first step in the design and development of effective protective clothing/products and safety protocols to safeguard the health of Australians involved in the defence of Australia.Read moreRead less
Fate of micropollutants in water recycling: influence of dissolved organic matter. Access to safe drinking water is essential for the economic and social development of Australia. There is increasing interest in applying advanced water treatment processes, such as membrane filtration or ozonation, to treat secondary effluent to a potable standard.

Access to safe drinking water is essential for the economic and social development of Australia. There is increasing interest in applying advanced water treatment processes, such as membrane filtration or ozonation, to treat secondary effluent to a potable standard. This project promotes improved organic pollutant removal and monitoring during advanced water treatment and will contribute to the National Research Priority goal, water - a critical resource, by providing the increased protection of receiving waters including rivers and seawater. Further, as very few studies consider the role of dissolved organic matter for organic pollutant fate in water reuse internationally, this project will help to advance Australia's position in science.Read moreRead less
