Effect of modification of structural and cellular properties of the arterial wall on functional stiffness of large arteries. The Australian population is ageing, becoming more obese and showing earlier onset of age-related conditions such as high blood pressure, heart failure and inflammatory disorders. All these conditions are associated with possible increase arterial stiffness. Inflammatory disorders in Australia affect one in six people, increasing to one in five in the next decade.

The Australian population is ageing, becoming more obese and showing earlier onset of age-related conditions such as high blood pressure, heart failure and inflammatory disorders. All these conditions are associated with possible increase arterial stiffness. Inflammatory disorders in Australia affect one in six people, increasing to one in five in the next decade. An equal proportion is affected by cardiovascular disease. This combined effect poses a massive burden on the national health budget. This project aims to investigate basic mechanism leading to degeneration of function of larger arteries and therapies to reverse the process and reduce cardiovascular risk in the community.Read moreRead less

Summary
High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in heal ....High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in healthcare, through clinical gait analysis and gait rehabilitation (diagnosis, prevention and treatment of movement disorders); in sports, through the development of personalized training programs for elite athletes; and in entertainment, through the creation of physics-based animations for the video/digital games industry.Read moreRead less
Determination of benchmarking parameters for assessing the mechanical robustness of articular cartilage: a joint mathematical and experimental investigation. Osteoarthritis associated with the deterioration of the articular cartilage affects about 12% of Australian adults. This project will use an integrated approach combining novel mathematical modelling and an extensive experimental program to establish critical mechanical parameters, in particular, the fracture toughness of articular cartilag ....Determination of benchmarking parameters for assessing the mechanical robustness of articular cartilage: a joint mathematical and experimental investigation. Osteoarthritis associated with the deterioration of the articular cartilage affects about 12% of Australian adults. This project will use an integrated approach combining novel mathematical modelling and an extensive experimental program to establish critical mechanical parameters, in particular, the fracture toughness of articular cartilage and will incorporate the unique structure of the dissimilar layers in articular cartilage. It will be used to study how these resist the propagation of an initiated crack and will offer significant insight into the desirable fracture properties of any replacement material for articular cartilage and will provide a basis for assessing replacement biomaterials.Read moreRead less
Drug-delivery coating for a new generation of orthopaedic implants. In Australia, the number of people using artificial implants in orthopaedic and dental surgeries is rapidly increasing due to the higher average age of the population and higher expectations for an active and healthy life. The project will enhance the success rate of titanium implants by increasing the strength and stability of tissue at the interface between implant and host, particularly in case of hip joint implants, reducing ....Drug-delivery coating for a new generation of orthopaedic implants. In Australia, the number of people using artificial implants in orthopaedic and dental surgeries is rapidly increasing due to the higher average age of the population and higher expectations for an active and healthy life. The project will enhance the success rate of titanium implants by increasing the strength and stability of tissue at the interface between implant and host, particularly in case of hip joint implants, reducing the need for revision surgery.

Computer simulation techniques to reduce the incidence of femoral fracture after hip replacement surgery. Australia's ageing population is driving an increase of 5% to 10% a year in the number of primary total hip replacements. We will move beyond conventional surgical techniques, to deliver the science for an accurate, reliable computer-based system that is significantly more accurate and reliable. Optimising implant selection criteria to better match patients' activity levels and bone physiolo ....Computer simulation techniques to reduce the incidence of femoral fracture after hip replacement surgery. Australia's ageing population is driving an increase of 5% to 10% a year in the number of primary total hip replacements. We will move beyond conventional surgical techniques, to deliver the science for an accurate, reliable computer-based system that is significantly more accurate and reliable. Optimising implant selection criteria to better match patients' activity levels and bone physiology and minimise revision rates; this has major implications for the national health budget and patients' quality of life. Our advances will allow the implementation of improved surgical techniques that minimise the risk of implant related bone failure.Read moreRead less
Proteomic and Transcriptional Profiling of Cartilage. Gene expression and signalling pathways that regulate cartilage formation, and its orderly transition to bone, are poorly described. Our studies will, for the first time, combine two complementary cutting-edge approaches, protein identification by proteomic analysis, and mRNA profiling by microarray analysis, to define these pathways and develop a comprehensive catalogue of proteins and gene expression patterns during cartilage development a ....Proteomic and Transcriptional Profiling of Cartilage. Gene expression and signalling pathways that regulate cartilage formation, and its orderly transition to bone, are poorly described. Our studies will, for the first time, combine two complementary cutting-edge approaches, protein identification by proteomic analysis, and mRNA profiling by microarray analysis, to define these pathways and develop a comprehensive catalogue of proteins and gene expression patterns during cartilage development and bone formation. This information will provide insight into the regulation of cartilage differentiation, maturation and structure, and will provide a critical platform for the development of more sophisticated cartilage and bone biomaterials for improved tissue repair and regeneration.Read moreRead less
