There is a strong potential for Australia to have an important stake in this area by combining expertise in engineering, chemistry and nanostructured materials.Read moreRead less
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

A comparative study of the distribution and spread of potential molecular markers for Mundulla Yellows disease. Mundulla Yellows (MY), a newly recognised widespread lethal disease of Eucalyptus spp.in Australia, is a serious threat to national biodiversity and conservation. It is contagious, apparently biotic, but the causal agent is unknown. Identification of the cause is essential to establish sustainable control measures. We have detected a range of MY-associated RNAs constituting a disease ' ....A comparative study of the distribution and spread of potential molecular markers for Mundulla Yellows disease. Mundulla Yellows (MY), a newly recognised widespread lethal disease of Eucalyptus spp.in Australia, is a serious threat to national biodiversity and conservation. It is contagious, apparently biotic, but the causal agent is unknown. Identification of the cause is essential to establish sustainable control measures. We have detected a range of MY-associated RNAs constituting a disease 'fingerprint'. To identify individual RNAs uniquely associated with MY we aim to compare MY-RNA fingerprints from a range of affected species from different sites and with varying symptoms. Candidate RNAs will be cloned both for establishing molecular diagnostics for MY and identifying the cause.Read moreRead less
New uses for milk-derived products for eradication of Helicobacter pylori infection and gastro-intestinal site-specific delivery of active agents. Helicobacter pylori is the most significant bacterial pathogen in the world, infecting 50% globally. Current treatments are inducing rapid antibiotic resistance and are thus becoming increasingly less effective. The infection is acquired in childhood and new methods to prevent and/or treat the infection, minimising acquisition of antibiotic resistance ....New uses for milk-derived products for eradication of Helicobacter pylori infection and gastro-intestinal site-specific delivery of active agents. Helicobacter pylori is the most significant bacterial pathogen in the world, infecting 50% globally. Current treatments are inducing rapid antibiotic resistance and are thus becoming increasingly less effective. The infection is acquired in childhood and new methods to prevent and/or treat the infection, minimising acquisition of antibiotic resistance are urgently required. This project seeks to develop new ways of doing this that combine novel antibacterials with techniques to deliver them (and monitor this delivery) as well as modify the complex protective habitat in the stomach.Read moreRead less
Improved methods for quantitation of acute phase proteins in biological samples. Using monoclonal antibodies and fluorescence polarisation, we aim to develop improved quantitative analytical methods that are superior to the current clinical assays. The initial targets will be C-reactive protein (CRP) and serum amyloid precursor protein (SAP), but the technology should be readily adaptable to other serum proteins. Better assays for CRP and SAP will greatly facilitate improved clinical management ....Improved methods for quantitation of acute phase proteins in biological samples. Using monoclonal antibodies and fluorescence polarisation, we aim to develop improved quantitative analytical methods that are superior to the current clinical assays. The initial targets will be C-reactive protein (CRP) and serum amyloid precursor protein (SAP), but the technology should be readily adaptable to other serum proteins. Better assays for CRP and SAP will greatly facilitate improved clinical management of those at risk of heart attack, the single biggest contributor to healthcare costs in Australia. We further aim to adapt this technology to enable "point-of-care" assays that would help medical practitioners, especially in rural areas, to make informed diagnoses immediately.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

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
