Development of Novel Two-dimensional Techniques for Magnetic Resonance In-vivo Spectroscopy. Body chemistry alters with functionality, pain, ageing and disease. These changes can be recorded by magnetic resonance (MR) spectroscopy (MRS) in vivo in a whole body MR scanner. When changes in chemistry can be recorded rapidly, and the individual species assigned, it will be possible to make a definitive diagnosis and in some cases allow the tailoring of treatment on an individual basis.

These changes can be recorded by magnetic resonance (MR) spectroscopy (MRS) in vivo in a whole body MR scanner. When changes in chemistry can be recorded rapidly, and the individual species assigned, it will be possible to make a definitive diagnosis and in some cases allow the tailoring of treatment on an individual basis. This is currently hampered by our inability to separate the composite resonances in a one dimensional MR spectrum. Research will allow two dimensional MRS to be implemented and provide detailed chemical information on human organs in vivo. 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 tests will rely on monoclonal antibodies to dete ....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 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
Gastrointestinal parasites and their diagnosis. Gastrointestinal disease such as diarrhoea, abdominal pain and irritable bowel syndrome are common in the Australian population and there are a wide variety of causes, including potentially parasites. The parasite Dientamoeba fragilis has, until recently, been overlooked as a cause of human disease, but recent studies have confirmed its role as a pathogen. This project seeks to improve the diagnosis of this organism in faeces and this development ....Gastrointestinal parasites and their diagnosis.

The parasite Dientamoeba fragilis has, until recently, been overlooked as a cause of human disease, but recent studies have confirmed its role as a pathogen. This project seeks to improve the diagnosis of this organism in faeces and this development will allow effective treatment to be used in patients thereby ameliorating disease.Read moreRead less
Rare isotopes as tracers of prosthesis debris. The incidence of knee replacement surgery in Australia is 30,000 per year. Limited by wear debris, the lifespan of knee implants is only 10-15 years and can be much shorter. Due to increasing life expectancy, many patients need several surgical procedures. As a multi-disciplinary team of materials-, isotope-tracing- and medical-experts, we aim to understand and monitor wear debris in prostheses. Knee replacement surgery alone imposes a high burden o ....Rare isotopes as tracers of prosthesis debris. The incidence of knee replacement surgery in Australia is 30,000 per year. Limited by wear debris, the lifespan of knee implants is only 10-15 years and can be much shorter. Due to increasing life expectancy, many patients need several surgical procedures. As a multi-disciplinary team of materials-, isotope-tracing- and medical-experts, we aim to understand and monitor wear debris in prostheses. Knee replacement surgery alone imposes a high burden of annually half a billion dollars on the Australian health budget. Controlling and reducing wear debris in prosthesis joints would reduce these costs and improve patients' quality of life.Read moreRead less
Novel Motion Correction Technologies for Simultaneous Positron Emission Tomography and Magnetic Resonance Imaging. The recent development of the world's first prototype combined MR-PET scanner for human use has prompted immense interest.

The recent development of the world's first prototype combined MR-PET scanner for human use has prompted immense interest. MR-PET is likely to revolutionize clinical diagnosis and basic research, by providing exquisite structural images co-registered with simultaneous functional PET images. We will exploit the as yet unexplored potential for motion information derived from the MR system to be used to correct the simultaneously acquired PET data for patient motion. This research is an excellent opportunity for Australian researchers to make important contributions to an emerging technology with high economic potential, and will strengthen Australia's international position in engineering and biomedical systems development.Read moreRead less
Automated pathogen detection using time-gated luminescence microscopy. A rapid and general means of in-situ pathogen identification would benefit the community by ensuring that appropriate treatments can be applied in the early stages of a disease. Patient prognosis is thereby improved and opportunities for multi-drug resistant organisms to arise are limited. Time-gated luminescence microscopy (TgM) exploits persistent luminescence to overcome autofluorescence, a serious problem in pathogen dete ....Automated pathogen detection using time-gated luminescence microscopy. A rapid and general means of in-situ pathogen identification would benefit the community by ensuring that appropriate treatments can be applied in the early stages of a disease. Patient prognosis is thereby improved and opportunities for multi-drug resistant organisms to arise are limited. Time-gated luminescence microscopy (TgM) exploits persistent luminescence to overcome autofluorescence, a serious problem in pathogen detection. Drug-resistant 'Golden Staph' (MRSA) will be used as the model organism to evaluate TgM efficacy. Ultimately however, TgM will be applied for the detection of tuberculosis, a highly contagious disease affecting the respiratory system of more than one-third of the world's population.Read moreRead less
DEEP DRILLING OF THE HUMAN PLASMA PROTEOME. Like turning out city lights lets you see the faint stars more clearly - removal of high abundance proteins from human biofluids allows quantum leaps in biomarker discovery. This project will develop products that remove the biggest obstacle in proteomics - high abundance proteins (city lights).

This project will develop products that remove the biggest obstacle in proteomics - high abundance proteins (city lights). Cheap, efficient and routine removal of abundant proteins will amplify the power of ?cutting edge? proteomic technologies in the discovery of novel biomarkers. This is possible because undiscovered low copy number biomarkers (faint stars) exist in human diagnostic fluids at levels far lower than current proteomic array detection limits.Read moreRead less

Development of new methods to measure in vivo properties of human body tissues. This project will develop new methods of noninvasively measuring the viscoelastic properties of soft tissues in live humans, using a novel magnetic resonance elastography technique. These methods will be applied to study the operation of the human muscle-tendon system, differences in neck muscle properties with age and gender and to measure the properties of the human brain, kidney and liver in vivo.

This project will develop new methods of noninvasively measuring the viscoelastic properties of soft tissues in live humans, using a novel magnetic resonance elastography technique. These methods will be applied to study the operation of the human muscle-tendon system, differences in neck muscle properties with age and gender and to measure the properties of the human brain, kidney and liver in vivo. These techniques may be useful in diagnosing soft tissue disease or injury which are currently difficult to detect using standard imaging techniques. It will also explain how the muscle-tendon unit moves during normal motion in live humans.Read moreRead less
