Summary
We have discovered that mutations in a calcium channel gene, TRPV4, cause an inherited osteoarthritis in the hands and feet. This work suggests that TRPV4 may be important in osteoarthritis and suggests the exciting possibility that modulating TRPV4 activity may provide a new therapeutic approach for arthritis. We will study how and why the mutations disrupt channel function and study mouse models to see if they are more or less susceptible to arthritis.
Ross River virus - identification of virulence determinants in clinical isolates from across Australia. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. The project has several national benefits. It will elucida ....Ross River virus - identification of virulence determinants in clinical isolates from across Australia. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. The project has several national benefits. It will elucidate whether there is any association between RRV strain and the severity of human disease. It will also identify viral markers that could assist public health officials in determining likely disease outcomes of outbreaks and could provide new avenues for the design of antiviral strategies.Read moreRead less

While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. This project has several national benefits. It will elucidate whether there is an association between RRV strain and the severity of disease and if there are human factors that affect the seriousness of symptoms. Knowledge of both of these could provide new avenues for the design of prevention and treatment strategies.Read moreRead less
BioPolymer Fibres For Remodelling Mdx And Damaged Muscle

$527,286.00
Summary
This project aims to generate new, smart polymers for use in re-building muscle that has degenerated due to disease and-or trauma damage. The merger of smart polymers with biologically based solutions and cells has great potential to improve outcomes of treatments of damaged muscle in diseases such as Muscular Dystrophy.
Fibre-Polymer Composites With Graded Microstructure. This project concerns the development of a novel fibre-polymer functionally graded composite material that mimics the structure of the spinal disk. The spinal disk comprises a soft core (nucleus) and a tough fibrous periphery (annulus). The graded composite approach of this proposal represents a significant advance over spinal fusion, and over the current generation of spinal disk protheses (metal plates with springs/polymers as shock absorber ....Fibre-Polymer Composites With Graded Microstructure. This project concerns the development of a novel fibre-polymer functionally graded composite material that mimics the structure of the spinal disk. The spinal disk comprises a soft core (nucleus) and a tough fibrous periphery (annulus). The graded composite approach of this proposal represents a significant advance over spinal fusion, and over the current generation of spinal disk protheses (metal plates with springs/polymers as shock absorbers). Chronic back pain affects a significant proportion of the population and is primarily caused by failure of the spinal disk. Therefore a strong social and economic imperative exists to develop engineering solutions to this problem.Read moreRead less
Patient-specific biomechanical modelling for improved treatment of spinal deformity. Spinal deformities negatively affect social acceptance, physical and mental wellbeing in children and adolescents. The direct costs of spinal deformity surgery are approximately $30 million per year in Australia, yet poor treatment outcomes due to post-operative complications incur a much higher cost as patients with persistent pain and disability face a lifetime of dependency and reduced ability to work. The pa ....Patient-specific biomechanical modelling for improved treatment of spinal deformity. Spinal deformities negatively affect social acceptance, physical and mental wellbeing in children and adolescents. The direct costs of spinal deformity surgery are approximately $30 million per year in Australia, yet poor treatment outcomes due to post-operative complications incur a much higher cost as patients with persistent pain and disability face a lifetime of dependency and reduced ability to work. The patient-specific biomechanical modelling techniques developed in this project will reduce complications and improve correction for Australian children who undergo spinal deformity surgery. Better treatment outcomes will ensure quality of life, health and productivity for spinal deformity patients throughout their entire lives.Read moreRead less
The virtual human knee. This project aims to investigate the Virtual Human Knee (VHK) which provides a baseline knowledge about knee mechanics in healthy individuals and a tool for studying knee mechanics in silico. The new knowledge can be used for identifying individuals most at risk for injury, developing solutions for preventing injury and for assessing knee reconstruction and implantation methods. As such, VHK will mitigate the burden of knee injury to Australia and worldwide by progressing ....The virtual human knee.

The new knowledge can be used for identifying individuals most at risk for injury, developing solutions for preventing injury and for assessing knee reconstruction and implantation methods. As such, VHK will mitigate the burden of knee injury to Australia and worldwide by progressing disciplines including anatomy, bio-mechanics, sport science, rehabilitation, surgery and medical devices.Read moreRead less
Inter-fragmentary movement in callus formation in the early phase of fracture healing. Computational models of the early phase of bone fracture healing can provide the means to characterise the biochemical factors that control this process, and subsequently influence successful healing outcomes, with or without surgical intervention.

Computational models of the early phase of bone fracture healing can provide the means to characterise the biochemical factors that control this process, and subsequently influence successful healing outcomes, with or without surgical intervention. This unique approach, incorporating soft tissue and fixation device contributions to fracture healing, will ultimately provide a sound basis for clinical decision-making, implant design and future experimental studies. Facilitating treatment optimisation, the outcomes of this project will create opportunities to reduce healthcare costs, physical impairment, and productivity losses for the 150,000 Australian patients hospitalised annually with fractures.Read moreRead less
Formation of bone-like materials for bone repair and regeneration. A successful outcome for this project would lead to the production and application of new bone-like calcium phosphate materials. Enhanced bioactivity of this material would lead to higher but controlled rates of calcium phosphate release. An understanding of the formation process of these materials and the controlled release of calcium phosphates has the potential to slow the development of metabolic diseases such as osteoporosis ....Formation of bone-like materials for bone repair and regeneration.

Enhanced bioactivity of this material would lead to higher but controlled rates of calcium phosphate release. An understanding of the formation process of these materials and the controlled release of calcium phosphates has the potential to slow the development of metabolic diseases such as osteoporosis. The WHO reports that osteoporosis is the second largest health care problem world-wide. In 2002, 44 million people in the USA were estimated to be at risk. This and similar figures in Australia and around the world emphasize the urgency of understanding and appropriately combating weak bone degenerative diseases.Read moreRead less
