The research described in this proposal aims to develop novel therapeutic compounds which target CD44 whilst eliciting a therapeutic index. The design of these new therapeutics is based on a template structure which incorporates known cytotoxic or anti-fungal agentsas well as hyaluronan, a naturally occurring carbohydrate, ubiquitous in nature.Read moreRead less
The first integrated multimodal assay for the ultrasensitive detection of dengue contamination of blood. This project will develop the first screening test to check for dengue contamination of blood donations in Australia. This will help ensure safe, continued supply from blood donors, particularly in Queensland where dengue is on the rise.
Investigating a novel, physical adjuvant for improving immune responses of vaccines. This project will explore a new way to significantly improve vaccine immune responses: with practical devices that apply pressure on the skin - for the body to create its own, localised adjuvant. This is novel - completely different to today's adjuvants, which are chemicals put into our bodies.
Development of carbohydrate-based drug delivery systems. Chronic skin disorders affect 5% of the population. Treatment is challenging and long term because these disorders are chronic and unpredictable. Currently the most potent therapies for psoriasis are administered systemically. Long term usage of these therapies causes side effects such as kidney or liver damage. This proposal describes a new approach to the topical treatment of psoriasis where potent drugs are linked to a hyaluronan sca ....Development of carbohydrate-based drug delivery systems. Chronic skin disorders affect 5% of the population. Treatment is challenging and long term because these disorders are chronic and unpredictable. Currently the most potent therapies for psoriasis are administered systemically. Long term usage of these therapies causes side effects such as kidney or liver damage. This proposal describes a new approach to the topical treatment of psoriasis where potent drugs are linked to a hyaluronan scaffold molecule and are directly applied to the diseased tissue. Advantages of this approach include targeted drug delivery mediated by hyaluronan receptor processes and potential amelioration of the observed drug toxicities.Read moreRead less
Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to ....Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to improve radiotherapy treatments in patients with small lesions with sizes of up to a few centimetres. This will lead to an improved outcome for some cancer patients.Read moreRead less
Screening platforms for malaria drug discovery: identification of new therapeutics. Innovative image based technologies will be developed to identify molecules which stop malaria parasite growth and its transmission to the mosquito host. As more resistance is emerging against the current drugs of choice, new molecules acting through different mechanisms are urgently needed.
Noval design of a Bi-Ventricular Assist Device (BVAD) Centrifugal Heart Pump as an Implantable Total Artificial Heart. In Australia, 40%(50,797) of all deaths each year are related to heart disease and accounted for 12% (A$4Billion) of total recurrent health expenditure. This innovative research aims at developing a single biventricular assist device (BVAD) driven by a magnetically suspended double-sided centrifugal pump impeller. Current techniques require two implantable devices, thus preventi ....Noval design of a Bi-Ventricular Assist Device (BVAD) Centrifugal Heart Pump as an Implantable Total Artificial Heart. In Australia, 40%(50,797) of all deaths each year are related to heart disease and accounted for 12% (A$4Billion) of total recurrent health expenditure. This innovative research aims at developing a single biventricular assist device (BVAD) driven by a magnetically suspended double-sided centrifugal pump impeller. Current techniques require two implantable devices, thus preventing smaller patients from access to BVAD technology. The expected outcomes will be a significantly small and compact device and provide an alternative to open-heart transplantation, thus helping to alleviate the demand on donor hearts, as well as the strain on the Australian Heath Care System caused by cardiovascular disease.Read moreRead less
DNA methylation-based diagnosis of cancer and identification of novel therapeutic targets. In our aging society, cancer represents a severe economic and quality-of-life threat. DNA methylation switches genes off, and recently, it was shown that defects in DNA methylation contribute to human diseases including cancer. This project will identify defects in DNA methylation associated with cancer. Identifying these defects will enable us to design non-invasive, early diagnostic tests for cancer on b ....DNA methylation-based diagnosis of cancer and identification of novel therapeutic targets. In our aging society, cancer represents a severe economic and quality-of-life threat. DNA methylation switches genes off, and recently, it was shown that defects in DNA methylation contribute to human diseases including cancer. This project will identify defects in DNA methylation associated with cancer. Identifying these defects will enable us to design non-invasive, early diagnostic tests for cancer on blood or bodily excretions, and to pursue novel therapeutic approaches for treating cancer. The expected outcomes would generate exports to markets in the USA and Europe and replace imports of drugs and technology to treat cancer.Read moreRead less

Development of technologies to monitor multimolecular complexes. This project aims to develop technologies to monitor how proteins and their interacting molecules (such as hormones) form multi-component complexes, and how these complexes function in the cell, including movement from the cell surface, into different cellular compartments and back up to the surface. These technologies are expected to enable monitoring in live cells in real-time with high sensitivity. This project could have broad benefits for and affect study of all aspects of the life sciences at the cellular and molecular levels. How these protein complexes function in cells underpins much of our understanding of biology, and technological tools.Read moreRead less
Coproantigen detection tests for diagnosis of intestinal parasitic nematode infection. The aim of this project is to develop new tests for detection of hookworm and Strongyloides, two common intestinal worm infections of humans. These tests offer the potential to replace current tests, namely stool microscopy and serodiagnosis, both of whose performance is unsatisfactory due to deficiencies in sensitivity, specificity and operator convenience.

The aim of this project is to develop new tests for detection of hookworm and Strongyloides, two common intestinal worm infections of humans. These tests offer the potential to replace current tests, namely stool microscopy and serodiagnosis, both of whose performance is unsatisfactory due to deficiencies in sensitivity, specificity and operator convenience. The tests will rely on monoclonal antibodies to detect parasite products in stool. Such testing technology is amenable to configuration in a robust format, suitable for large-scale manufacture. Given the worldwide prevalence of these parasites, the tests will have a market potential of international significance.Read moreRead less
