Summary
Malaria is a major global health problem. 500 million people become infected with malaria parasites every year and 2-3 million people die each year from the disease. Rapid diagnosis of the disease is needed to allow correct treatment protocols. 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.

Rapid diagnosis of the disease is needed to allow correct treatment protocols. 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

Summary
Quantum Dots, a type of nanocrystal, have been shown to emit light at a very precise wavelength. Quantum dots of approximately 5 nm in diameter have been conjugated to a silica microsphere and then coated with free silica, thus encasing the Quantum Dots in a small chamber surrounding the microsphere. This structure is analogous to a light globe under a lampshade. Just as one can change the nature of the lamplight by changing the lampshade, one can change the Quantum Dot emitted light by changing ....Quantum Dots, a type of nanocrystal, have been shown to emit light at a very precise wavelength. Quantum dots of approximately 5 nm in diameter have been conjugated to a silica microsphere and then coated with free silica, thus encasing the Quantum Dots in a small chamber surrounding the microsphere. This structure is analogous to a light globe under a lampshade. Just as one can change the nature of the lamplight by changing the lampshade, one can change the Quantum Dot emitted light by changing the surface of the microsphere. Since the scale is so small (each microsphere is about the size of a single bacterial cell), the amount and nature of the material needed to bind to the surface to effect a detectable change is also very small, on the order of just of few tens or hundreds of molecules. This project seeks to exploit this principle to create a new class of ultra sensitive detector which can be used in many sorts of applications such as medical diagnostics and biosensing.Read moreRead less
Development Of A Serum Based Test For Aggressive Prostate Cancer.

Summary
Prostate cancer is relatively slow growing, taking decades to reach clinical significance. A critical phase in the progression of prostate cancer is the transformation from latent (or dormant) to aggressive tumours; hence the saying that many men die with prostate cancer, rather than of prostate cancer. We aim to develop a test utilising inhibin-activin proteins as surrogate markers of aggressive disease based on our previous studies of a significant correlation between the expression of inhibin ....Prostate cancer is relatively slow growing, taking decades to reach clinical significance. A critical phase in the progression of prostate cancer is the transformation from latent (or dormant) to aggressive tumours; hence the saying that many men die with prostate cancer, rather than of prostate cancer. We aim to develop a test utilising inhibin-activin proteins as surrogate markers of aggressive disease based on our previous studies of a significant correlation between the expression of inhibins in tissues from men with high grade prostate cancer. This study aims to validate the correlation using serum rather than a tissue based assay.Read moreRead less

Summary
This research aims to develop a diagnostic for immediate monitoring of patients presenting with chest pain, with the presumption of heart attack. The novel diagnostic platform will enable the estimation of a key indicator of heart muscle damage to be performed within a ten to fifteen minute window. This will aid speedier diagnosis and propoer triage of patients presenting with chest pain.

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
Many repetitive regions of genomes are difficult to sequence and to assemble. �Sequencing Aided by Mutation� (SAM) is a new sequencing technology, which overcomes many of the difficulties that hinder current sequencing methods. SAM involves forming randomly mutated copies of the target DNA.

Rapid HIV-1 Tropism Testing Using Novel, Soluble Mimics Of The HIV-1 Coreceptors CCR5 And CXCR4

$163,426.00
Summary
This proposal seeks to develop an inexpensive assay to determine whether HIV patients will benefit from treatment with new drugs referred to as CCR5 antagonists. These are effective against HIV strains that use the CCR5 coreceptor, therefore a patient�s HIV coreceptor usage must be assessed before commencing therapy. Current assays are complicated, slow and expensive. Using novel, soluble mimics of the coreceptors we will develop an ELISA based test that can be operated using standard equipment.
NaviGAIT: New Software To Simplify Interpretation Of Gait Analysis Data

Summary
NaviGAIT is a new software package to support interpretation of gait analysis data. It is based upon Gait Profiling, a new technique to reduce the complexity of such data. At present data intepretation is restricted to a few expert clinicians. The new software will allow non-expert clinicians to interpret data and hence make gait analysis more accessible, cheaper and more clincally useful. A module of NaviGAIT specifically for children with cerebral palsy will be the first to be developed.
We will conduct a clinical trial of the effectiveness of a continuous auditory display of an anesthetized patient's respiratory status. Expired carbon dioxide monitoring has helped reduce respiratory incidents since its widespread introduction in the late 1980s, but a continuous auditory display of respiratory status may reduce incidents further. We will conduct a clinical trial with 10 anaesthetists of continuous auditory respiratory monitoring. Successful outcome may lead to commercial uptake.

It is planned to utilize this module in the design of customized new commercial PET scanners ideal for diagnosing human brain and breast disorders. The development will proceed in collaboration with Insight Oceania-ADAC, Sydney. Insight Oceania-ADAC are very excited by the potential applications and future markets (Australia and overseas) of the newly developing PET detection sub-modules for dedicated PET scanners. Positron Emission Tomography (PET) is a functional imaging tool, which is able to quantify physiological and biochemical processes in vivo, using short-lived cyclotron-produced radiotracers. PET is emerging as an extremely important diagnostic procedure used in the early detection of cancers, neurological diseases and as an aid in treatment monitoring and drug development. The unique advantage of PET over anatomical imaging techniques, such as X-ray CT and MRI, arises from its ability to measure changes in tumour biology, at the molecular level, prior to anatomical changes in involved tissues, using trace amounts of a radiolabelled compound (radiotracer). The full potential of PET however, is not being completely utilized due to constraints within the current designs of PET scanners. When used to its full potential PET, in principle, would be an excellent diagnostic and treatment monitoring tool for breast cancer, brain tumours and other neurological conditions such as epilepsy, Alzheimer's, Parkinson's disease, post stress disorder, dementia, and depression. Lack of flexibility in current PET scanner designs to date has meant that no commercial human brain or breast imaging scanners exist. Pilot project data proved the feasibility of our new flexible PET detection module design.Read moreRead less
