Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
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.

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

Self-assembled nanolayers of functionalised latexes as selective and adaptable nano-stationary phases in separation science. A new approach is proposed for the design and synthesis of functionalised ion-exchange stationary phases for analytical nano-separation methods. Desired charged functional groups are first affixed chemically onto nanometre sized latex particles and these particles are then self-assembled mechanically as monoloayer coatings onto a suitable supporting template such as fused ....Self-assembled nanolayers of functionalised latexes as selective and adaptable nano-stationary phases in separation science. A new approach is proposed for the design and synthesis of functionalised ion-exchange stationary phases for analytical nano-separation methods. Desired charged functional groups are first affixed chemically onto nanometre sized latex particles and these particles are then self-assembled mechanically as monoloayer coatings onto a suitable supporting template such as fused silica, monolithic silica or polymer beds, microfibres or microtubes, and channels in microchips. The resultant coated surface then acts as a highly efficient ion-exchange stationary phase which will be used in a wide range of separation technologies including ion chromatography, capillary electrophoresis, capillary electrochromatography and solid-phase microextraction.Read moreRead less

Due to the way in which multiple processes are integrated in a micro Total Analysis System (µTAS), they offer substantial advantages over current technology, in terms of speed, cost of analysis, portability and operator simplicity and safety. This has considerable potential benefit for Australia, specifically for the remote and rural analysis of drugs and metabolites in biological fluids such as blood, serum, urine and saliva. These devices will have application for point-of-care testing in therapeutic drug monitoring, which will improve medical treatment and the patient's quality of life, as well as for on-site analysis in forensics for the rapid determination of illicit drugs and performance enhancing substances in our elite athletes.
