Integrin Activation by Fluid Flow Disturbance: Mechanobiology Approaches. Understanding how cells can sense and respond to mechanical environment such as dynamic blood flow represents a fundamental question in the emerging field of mechanobiology. This project develops new biomechanical engineering approaches to determine the critical interrelationships among fluid flow disturbance, platelet clotting and the mechano-sensitive signal transduction mechanisms of integrin receptor – the most importa ....Integrin Activation by Fluid Flow Disturbance: Mechanobiology Approaches. Understanding how cells can sense and respond to mechanical environment such as dynamic blood flow represents a fundamental question in the emerging field of mechanobiology. This project develops new biomechanical engineering approaches to determine the critical interrelationships among fluid flow disturbance, platelet clotting and the mechano-sensitive signal transduction mechanisms of integrin receptor – the most important mechano-sensor implicated in cell adhesion, migration, growth and survival. Specifically, it integrates nationally unique cutting-edge techniques including single-molecule force probe, microparticle image velocimetry, microfluidics and molecular dynamics simulation, super resolution and 3D volumetric imaging modalities.Read moreRead less
Structures and properties of tissue engineering matrices for cartilage and bone: Imaging, visualising and modelling tissue/scaffold constructs in 3D. Tissue engineering of bone and cartilage has the potential to lower costs and improve outcomes. The first stage requires the design of porous 3D scaffolds. To date they have been found less than ideal for clinical applications. Our ability to design and optimise scaffolds has been ad hoc, as local structure and properties have not been measurable ....Structures and properties of tissue engineering matrices for cartilage and bone: Imaging, visualising and modelling tissue/scaffold constructs in 3D. Tissue engineering of bone and cartilage has the potential to lower costs and improve outcomes. The first stage requires the design of porous 3D scaffolds. To date they have been found less than ideal for clinical applications. Our ability to design and optimise scaffolds has been ad hoc, as local structure and properties have not been measurable during tissue growth and repair. In this proposal, an interdisciplinary group from three universities will utilise microCT imaging, visualisation and numerical modelling to determine these structures and properties. This will provide an invaluable understanding for the further development of tissue engineering scaffolds.Read moreRead less
Assessing Bone Quality and Health: Experimental imaging, structural characterisation, and mechanical modelling of bone in 3D. Age-related bone fractures due to osteoporosis impose a significant social and economic problem on our increasingly aging population. The assessment of bone quality is important in the diagnosis of age related bone fragility and for studying the efficacy of therapeutic intervens. In this proposal a unique interdisciplinary group with expertise in bone and mineral research ....Assessing Bone Quality and Health: Experimental imaging, structural characterisation, and mechanical modelling of bone in 3D. Age-related bone fractures due to osteoporosis impose a significant social and economic problem on our increasingly aging population. The assessment of bone quality is important in the diagnosis of age related bone fragility and for studying the efficacy of therapeutic intervens. In this proposal a unique interdisciplinary group with expertise in bone and mineral research, experimental 3D imaging and the characterisation and modelling of complex materials will tackle the problem of assessing bone quality and health. The proposed research will greatly improve our assessment of the mechanical competence of bone.Read moreRead less
New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriat ....New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriate rigidity and toughness, and stimulate better bone growth at the interface. In this way the implant should be much longer lasting and the need for undesirable revision surgery reduced. The processing technique proposed could also be a useful platform coating technology in a number of other industries.Read moreRead less
Using nanostructured biomaterials and stem cells to repair spinal cord injuries. There is currently no effective cure for spinal cord injuries and the consequences to the patient are devastating. Spinal cord injuries affects limb, bowel, bladder and sexual function, and many people with these injuries strugle to maintain their independence. Because people can live for many years after spinal cord damage, the financial and social costs are immense, as many are dependent on the help of others for ....Using nanostructured biomaterials and stem cells to repair spinal cord injuries. There is currently no effective cure for spinal cord injuries and the consequences to the patient are devastating. Spinal cord injuries affects limb, bowel, bladder and sexual function, and many people with these injuries strugle to maintain their independence. Because people can live for many years after spinal cord damage, the financial and social costs are immense, as many are dependent on the help of others for their survival. This proposal tackles this urgent problem by applying advanced nanostructured materials with stem cells, to assist the body in the repair of the spinal cord following injury. Read moreRead less
