Nanoengineering of Biomaterial Surfaces to Tailor Innate Immune Responses. The overarching aim of this project is to provide a mechanistic understanding of how surface nanotopography affects inflammatory responses. Recently, we showed that surface nanotopography induced conformational changes in adsorbed proteins can activate or deactivate immune cells. These exciting findings are important because they show that it may be possible to engineer the nanotopography of a biomedical device surface in ....Nanoengineering of Biomaterial Surfaces to Tailor Innate Immune Responses. The overarching aim of this project is to provide a mechanistic understanding of how surface nanotopography affects inflammatory responses. Recently, we showed that surface nanotopography induced conformational changes in adsorbed proteins can activate or deactivate immune cells. These exciting findings are important because they show that it may be possible to engineer the nanotopography of a biomedical device surface in a manner which leads to a desired and predictable level of inflammation. The outcomes of the project will create new fundamental knowledge that in the future can instruct the development of the next generation of biomaterials capable of controlling and directing the body’s inflammatory responses.Read moreRead less
Towards early detection of upper airway obstruction in children: investigation of autonomic control. This project focuses on the investigation of new indicators for early detection of upper airway obstruction (UAO)-which is a common sleep disorder in children. Failure to treat UAO can result in serious adverse outcomes including failure to thrive, neurocognitive deficits, developmental delay, behavioural disorders and cardiovascular disease. Thus, early treatment of UAO will significantly improv ....Towards early detection of upper airway obstruction in children: investigation of autonomic control. This project focuses on the investigation of new indicators for early detection of upper airway obstruction (UAO)-which is a common sleep disorder in children. Failure to treat UAO can result in serious adverse outcomes including failure to thrive, neurocognitive deficits, developmental delay, behavioural disorders and cardiovascular disease. Thus, early treatment of UAO will significantly improve quality of life for the child. Direct benefits to community health via reduced costs for medical treatment will also be a key outcome. The establishment of new diagnostic indicators will form the basis of new tools for identifying child sleep disorders and contribute to advancing Australia's international leading position in health technology.

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.

This project aims to establish a Scanco microCT 50 high resolution X-Ray microtomography system, to non-destructively visualise and quantitatively characterise complex samples, including advanced composites, tissue engineering constructs, biological tissues, minerals and fossils. The non-destructive characterisation of these samples is critical to advance research. The versatile system offers high spatial resolution (down to 500 nm voxel size) and large sample size (up to 100 mm diameter). The project will enable progress in advanced composites, additive bio-manufacturing, physiology of biological tissues and palaeontology which will benefit Australian science. Additionally, through commercialisation and the formation of new companies, the project could potentially result in economic and health benefits to the wider Australian population and economy.Read moreRead less

Despite coating with hydroxyapatite, a material well known to improve implant fixation, many such implants fail because of lack of strong integration with bone. This proposal aims at achieving long-term stability of titanium implants through their surface modification and subsequent attachment of growth factors. The use of latter has already been shown to help bone-implant integration. Successful project implementation will provide titanium implant surfaces that will help achieve speedier and improved implant fixation with long-term stability. Knowledge, expertise and techniques developed will help the industry partner expanding its research base and business and generating wealth in Australia. Training of world-class research students in the emerging field of biotechnology will be another major outcome.Read moreRead less

Summary
Synchrotron-based modelling of the deformation and fracture mechanism in normal and osteoporotic femurs under multiaxial loading cycles. The femur is a light-weight structure designed to best perform in life. However, the complex tissue architecture, microstructural organisation and its complex loading regimens make it difficult to understand how the femur can deform and fracture. This project studies femoral fractures by modelling the proximal femur with a micrometric level of detail.

The femur is a light-weight structure designed to best perform in life. However, the complex tissue architecture, microstructural organisation and its complex loading regimens make it difficult to understand how the femur can deform and fracture. This project studies femoral fractures by modelling the proximal femur with a micrometric level of detail. Synchrotron femur images are taken in loaded and unloaded conditions. Cortical strain and fracture are measured, replicating possible multiaxial loads. Micro finite-element models will be used to study the contribution that the bone tissue architecture, tissue structure and activity types make to the fracture. The resulting knowledge will have future orthopaedic applications.Read moreRead less
