Blood flow routes in muscle. Ageing well, ageing productively. The Australian population is ageing. The proportion of the population over the age of 65 is expected to greatly increase, reaching 22% by the year 2030. The prevalence of type 2 diabetes in this older population is thought to be ~20%, compared to ~6% in younger populations. An initial cause of type 2 diabetes may be microvascular dysfunction brought on by physical inactivity. Therefore this project addresses the concepts of microvasc ....Blood flow routes in muscle. Ageing well, ageing productively. The Australian population is ageing. The proportion of the population over the age of 65 is expected to greatly increase, reaching 22% by the year 2030. The prevalence of type 2 diabetes in this older population is thought to be ~20%, compared to ~6% in younger populations. An initial cause of type 2 diabetes may be microvascular dysfunction brought on by physical inactivity. Therefore this project addresses the concepts of microvascular function and microvascular fitness by using the latest technology to map blood flow routes in muscle under a number of relevant situations.

Microdialysis for monitoring changes in microvascular flow patterns in muscle. Microdialysis is a technique for sampling interstitial fluid. Factors altering vascular delivery and removal of nutrients and hormones can affect muscle metabolism by altering exchange with the interstitium. This project focuses on microdialysis for assessing the impact of microvascular blood flow patterns on skeletal muscle metabolism and contractility. The aim is to develop and refine the technology, including equat ....Microdialysis for monitoring changes in microvascular flow patterns in muscle. Microdialysis is a technique for sampling interstitial fluid. Factors altering vascular delivery and removal of nutrients and hormones can affect muscle metabolism by altering exchange with the interstitium. This project focuses on microdialysis for assessing the impact of microvascular blood flow patterns on skeletal muscle metabolism and contractility. The aim is to develop and refine the technology, including equations, specifically for monitoring the nutritive fraction of blood flow in muscle by agents and factors relating to health and disease. This technique could be used for screening drugs in the treatment of diseases such as type 2 diabetes and related conditions.Read moreRead less
Enhancing sunscreen DNA and photo-ageing protection. Skin damage from UV exposure is costly for individuals and the community, particularly in Australia, where the population has predominantly fair skin. While public campaigns to persuade the population to use sun protection and avoidance have been useful, this project will be the first to extend this approach to deliver a way to reduce sun damage from any UV exposure that does nevertheless occur, by incorporating the active agents into topical ....Enhancing sunscreen DNA and photo-ageing protection. Skin damage from UV exposure is costly for individuals and the community, particularly in Australia, where the population has predominantly fair skin. While public campaigns to persuade the population to use sun protection and avoidance have been useful, this project will be the first to extend this approach to deliver a way to reduce sun damage from any UV exposure that does nevertheless occur, by incorporating the active agents into topical sunscreens or creams for after-sun use. The project will also build infrastructure for translational research on photo-damage, combining world-class facilities for this research with advanced formulation and manufacturing operations.Read moreRead less
Ultrasound in muscle vascular research, and gene therapy. This project focuses on ultrasound and microbubbles for the imaging of microvascular blood flow patterns in skeletal muscle and as a modality for drug delivery. The aim is to develop and refine technology specifically for (i) assessment of muscle microvascular flow in health and disease, and for (ii) delivery of state-of-the art gene constructs to endothelial cells that control blood flow in the muscle microvasculature.

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
Development of class-leading bioluminescence resonance energy transfer technologies for real-time monitoring of molecular interactions.

The expected outcome is the development of technologies that provide a level of sensitivity and data quality that enables adoption by the biotechnology and pharmaceutical industries.
Rapid detection of rare-event cells by strong UP-conversion
encoded nano-radiators (SUPER Dots): finding a needle in a haystack. Current diagnostic tests are not sensitive enough to detect cancer in its very early stages or early recurrence following treatment. The new technologies developed by this project will be able to find single cancer cells in blood and urine samples heralding a new era in medical diagnostics.
Beyond Spectral Detection: Engineering SUPER Dot Probes for High-Throughput Discovery. Molecules that are altered as a result of a pathological condition are generally present in very low abundance, and pose a “needle-in-a-haystack” problem. Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. This project will develop a new generation of nanophotonic luminescent probes (Strong Upconversion Photo-stable Encoded ....Beyond Spectral Detection: Engineering SUPER Dot Probes for High-Throughput Discovery.

Current detection, quantification and localisation technologies use fluorescent probes that are limited by sensitivity and analysis time. This project will develop a new generation of nanophotonic luminescent probes (Strong Upconversion Photo-stable Encoded nano-Radiators (SUPER) Dots), based on purpose-engineered up-conversion nanocrystals that are ultra-bright and have low background interference, high specificity, speed, and large-scale multiplexing capacity. These probes will allow microscopy and flow cytometry to measure hitherto undetectable rare-event molecules and cells, opening new frontiers for the discovery of new biomarkers.Read moreRead less
