Summary
The malaria elimination agenda will require the development of novel, field applicable diagnostic tools to detect asymptomatic carriers of P.falciparum and non-falciparum malaria infections. Loop-mediated isothermal amplification (LAMP) has been demonstrated to be a novel, sensitive, specific nucleic acid amplification technique. My project aims to optimise LAMP into a high-throughput field applicable molecular diagnostic tool capable of diagnosing malaria in elimination settings

New high resolution radiation dose mapping of special type polymer-gel dosimeters using mini-MRI scanner of high (4.7 Tesla) magnetic field. Gel dosimeters main advantage is dose determination in 3-dimensions. Their main limitation is low spatial-resolution. We propose fabrication of special-type gels and for the first time use the 4.7 Tesla mini-scanner for dose mapping.

Gel dosimeters main advantage is dose determination in 3-dimensions. Their main limitation is low spatial-resolution. We propose fabrication of special-type gels and for the first time use the 4.7 Tesla mini-scanner for dose mapping. Increased magnetic field combined with a small aperture for field dissipation will greatly improve spatial resolution down to micrometers (micro-dosimetry). This new technique will render gel-dosimeters suitable for applications in radiotherapy, industrial and all other radiation fields. Moreover, we will employ new parameter for dose mapping, which is expected to be more sensitive to radiation than the currently used relaxation timesRead moreRead less

Summary
The accurate measurement of the inherent pumping capacity of the heart muscle is difficult because (i) most measurements currently in use cannot accurately discriminate between the contribution of the heart muscle and that of the vascular system to the results obtained, and (ii) the measurements which can discriminate currently require invasive measurements and procedures that frequently restrict their use. The overall purpose of this proposal is to more rigorously validate a promising method we ....The accurate measurement of the inherent pumping capacity of the heart muscle is difficult because (i) most measurements currently in use cannot accurately discriminate between the contribution of the heart muscle and that of the vascular system to the results obtained, and (ii) the measurements which can discriminate currently require invasive measurements and procedures that frequently restrict their use. The overall purpose of this proposal is to more rigorously validate a promising method we have developed that will (i) make accurate assessment possible from a single cardiac beat in both experimental animals and human subjects; (ii) reduce the number of experimental animals required for such measurements by permitting sequential measurements in the same animals; (iii) make it possible to perform such measurements non-invasively in human subjects.Read moreRead less

Summary
Advances in nanotechnology have led to new techniques for the precise fabrication of nanometre scale structures. A recent breakthrough by the applicants now allows high-quality nanostructures to be stamped onto the tip of low-cost optical fibre probes. When coated with silver, these sensitive probes can be used for continuous monitoring of blood glucose in diabetics and in critical care situations. This project aims to develop a prototype manufacturing system for optical fibre glucose probes.

Summary
Lysosomal storage disorders (LSD) are a group of more than 45 progressive genetic diseases, that result from the absence or impaired function of a specific enzyme in each of the body's cells. Lysosomes rid the cell of excess waste. Impaired enzyme function halts this process and waste begins to accumulate (or 'store') in the cell. Disease severity and patient longevity is variable, but severely affected patients often die by their mid-teens.

Lysosomes rid the cell of excess waste. Impaired enzyme function halts this process and waste begins to accumulate (or 'store') in the cell. Disease severity and patient longevity is variable, but severely affected patients often die by their mid-teens. LSD can affect the skeleton and joints, respiratory and cardiovascular systems, the brain, the eyes, the ears and the airways. As affected children become older, symptoms worsen. Patients often require frequent hospitalisation, and medical and surgical intervention. Approximately 10 to 15% of the general population are affected or carriers of an LSD. In Australia, one LSD child is born in every 5,000 live births. Diagnosis often takes several years, and families often have other children before their affected child is diagnosed. LSD are, therefore, a considerable burden to not only the families but also to the health care system. The goal of the Lysosomal Diseases Research Unit is Diagnosis at birth and effective therapy for lysosomal storage disorders. To this end we have been working toward the development of a newborn screening program for LSD and improved methods for the diagnosis and monitoring of therapy in this group of diseases. In this project we propose to develop and evaluate the use of protein profiling (looking at many diagnostic markers at the same time) to achieve these goals. The technology developed in this project will have potential application beyond LSD. Lysosomal dysfunction has been implicated in Alzheimer's disease and Parkinson's disease; in addition lysosomal proteins are reported to be involved in the spread of some cancers and may be useful markers for early detection. We will collaborate with other research groups to further develop protein profiling in these areas.Read moreRead less

Increasingly protein-based immunochromatographic tests are being employed for the diagnosis of malaria as they offer significant advantages over classical thick smear tests, which require trained personnel and laboratory facilities. We propose to develop a protein-based malaria diagnostic that has the ability to distinguish the two major human pathogens, P.falciparum and P. vivax.Read moreRead less
Electric field induced surface attachment and detachment of proteins. Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites.

Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites. Ultimately microelectronic engineering methods will be used. This will give control over the attachment process with potential benefits of orienting attaching molecules, minimising non-specific attachment and enriching diagnostics by enabling interrogation of the force of attachment.Read moreRead less

ARC Research Hub for Integrated Device for End-user Analysis at Low-levels. This hub aims to improve detection of biological materials by building a portable device for rapid, time-critical detection of low-abundance molecular and cellular analytes. It is expected that the resulting technologies would be used at medical points of care, ordinary workplaces and centres of activity to test for tiny levels of targeted molecules. The initial focus would be early diagnosis of disease and point-of-care drug testing for humans and animals, but the technology platform could be used to sample food and environmental toxins. The hub expects these disruptive technologies will make Australian biotechnology, diagnostics, veterinary, agribusiness and manufacturing firms globally competitive.Read moreRead less
