Predicting the diagnostic performance of individuals and organisations. This project aims to address diagnostic error in advanced technology systems, by providing a mechanism to assess and improve individual diagnosticians’ performance. Organisations that rely on their employees’ diagnostic skills rarely assess them once the operators become qualified, so there is no basis for interventions that might prevent diagnostic errors affecting thousands. This research tests a new method of assessing diagnostic skills based on how skilled operators respond to cues. This project will test how employees’ diagnostic skills change and whether this change corresponds to measures of organisational performance. This research is expected to provide organisations with a tool to pre-empt diagnostic errors that could minimise costs to the economy.Read moreRead less
Imaging Mass Spectrometry (IMS), a peptide biomarker discovery tool using tissue. Cancer is the second most common cause of death in Australia. The newly developed technology of Imaging Mass Spectrometry for peptides in tissue has the potential to discover biomarkers for early diagnosis of cancer. This new technology could avoid a number of cancer deaths and reduce suffering of patients through earlier and better diagnosis.
A gold-coated magnetic nanoparticle biosensor for detecting microRNA. The project aims to develop a biosensor for detecting short sequences of RNA, called microRNA (miRNA) in blood. There are about 100 miRNA sequences that are involved in most biological processes. Changes in the levels of some miRNA sequences can serve as a biomarker for many diseases including cancers. The miRNA will be detected using gold-coated magnetic nanoparticles modified with DNA sequences complementary to the miRNA of ....A gold-coated magnetic nanoparticle biosensor for detecting microRNA. The project aims to develop a biosensor for detecting short sequences of RNA, called microRNA (miRNA) in blood. There are about 100 miRNA sequences that are involved in most biological processes. Changes in the levels of some miRNA sequences can serve as a biomarker for many diseases including cancers. The miRNA will be detected using gold-coated magnetic nanoparticles modified with DNA sequences complementary to the miRNA of interest to capture the miRNA. Application of a magnetic field allows the levels of miRNA to be detected electrochemically. The expected outcome is a commercialisable biosensor for miRNA both as a diagnostic early detection device and a prognostic device for a range of miRNA biomarkers.Read moreRead less
Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors w ....Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors will be used to devise a simple portable colorimetric test that can be performed in the vineyard or the winery. The ability to rapidly determine the level of grape contamination with phenolic glucosides would give Australian wine growers and wine makers a powerful tool to mitigate the effects of bushfires.Read moreRead less
Development of a diagnostic microarray to detect aneuploidy in single cells. Chromosomal abnormalities account for about 10 per cent of all babies born with a defect. The risk of chromosomal abnormalities increases with maternal age and in patients with fertility problems. It has been estimated that 50 per cent of all embryos are aneuploid. Chromosomal aberrations also occur in the vast majority of tumours in humans. Accurate and rapid detection of chromosomal defects is an important health ser ....Development of a diagnostic microarray to detect aneuploidy in single cells. Chromosomal abnormalities account for about 10 per cent of all babies born with a defect. The risk of chromosomal abnormalities increases with maternal age and in patients with fertility problems. It has been estimated that 50 per cent of all embryos are aneuploid. Chromosomal aberrations also occur in the vast majority of tumours in humans. Accurate and rapid detection of chromosomal defects is an important health service delivered to the Australian public. This project aims to develop better tests for application in prenatal diagnostics including non-invasive testing of fetal cells from maternal circulation or cervical samples at 6-13 weeks gestation, IVF and cancer diagnostics.Read moreRead less
Electrochemical biosensors for detection of cardiac disease markers in blood. Cardiovascular diseases leading to heart failure have a prevalence of over 16 per cent in Australia. The social, economic and health burden is higher than for any other disease group. Hence, it is critically important to develop fit-for-purpose sensors of known cardiac biomarkers, which alert patients and clinicians of the risk of imminent heart failure.
Pharmacological probes to facilitate preclinical development of modulators of a6 subunit containing nicotinic acetylcholine receptors. Allosteric modulators of alpha7 nicotinic acetylcholine receptors have a promising future as drugs targeting attention deficits in Alzheimer’s disease and schizophrenia but the mechanisms underlying modulation are poorly understood. This project aims to determine its binding site and develop a radioactive labelled compound that competes with its binding. The radi ....Pharmacological probes to facilitate preclinical development of modulators of a6 subunit containing nicotinic acetylcholine receptors. Allosteric modulators of alpha7 nicotinic acetylcholine receptors have a promising future as drugs targeting attention deficits in Alzheimer’s disease and schizophrenia but the mechanisms underlying modulation are poorly understood. This project aims to determine its binding site and develop a radioactive labelled compound that competes with its binding. The radiolabelled compound and a deeper insight into the mode of action will enable development of ligands for positron emission tomography (PET) which will aid in the development of BNC375 as well as other alpha7 modulators.Read moreRead less
