Summary
Chikungunya virus and Ross River virus cause epidemics of acute and chronic arthritic disease in humans, which is often poorly managed with current treatments. This grant seeks to understand the mechanisms that give rise to disease in order to identify improved treatment strategies. Both the persistence of viral replication in joint tissues and unnecessary inflammatory responses appear to be important factors driving chronic disease.

Summary
Metabolic disorders such as obesity, insulin resistance and type 2 diabetes are characterised by inappropriate handling of nutrients. Mitochondria are the primary site for nutrient oxidation in cells. Sirtuins such as SIRT3 and SIRT5 are abundant in mitochondria and may affect mitochondrial function and insulin action in skeletal muscle. Understanding the biochemical pathways involved in energy metabolism in skeletal muscle is crucial in the development of therapies for insulin resistance and ty ....Metabolic disorders such as obesity, insulin resistance and type 2 diabetes are characterised by inappropriate handling of nutrients.

The early osteoarthritis (OA) phenotype. Australia like many other developed countries is undergoing a major demographic shift involving significant growth in the aged population. From both a patient perspective and a societal perspective, research into the underlying determinants of osteoarthritis such as those outlined in this proposal are of great importance to the aged population. Nearly one in five Australians has arthritis; indeed more Australians have arthritis than any other national hea ....The early osteoarthritis (OA) phenotype. Australia like many other developed countries is undergoing a major demographic shift involving significant growth in the aged population. From both a patient perspective and a societal perspective, research into the underlying determinants of osteoarthritis such as those outlined in this proposal are of great importance to the aged population. Nearly one in five Australians has arthritis; indeed more Australians have arthritis than any other national health priority condition. From an individual point-of-view, the pain and disability due to osteoarthritis (OA) can lead to loss of independence and diminished in quality of life for older adults.Read moreRead less
Genetics of Postmenopausal Bone Loss. The major consequence of bone loss in our ageing society is fracture. At 50 years for women, the lifetime risk of sustaining an osteoporotic fracture is 50%. The consequences of these fractures, which can include reduced life expectancy, prolonged medical care, and loss of independence, have a profound socioeconomic impact in an ageing population. The proposed study offers a unique opportunity to examine the contribution of genetic factors to postmenopausal ....Genetics of Postmenopausal Bone Loss.

Program evaluation of the osteoarthritis awareness hub. Persons with osteoarthritis generally have poor knowledge about their disease and its appropriate management. The aim of this project is to evaluate whether improved knowledge, and management decisions of persons with osteoarthritis, can ultimately lead to improved health outcomes.
Novel human tryptases: their potential role in inflammatory diseases of the young and old. We have discovered a number of novel human tryptases, and while other members of this enzyme family have been implicated in the development of inflammatory diseases (including rheumatoid arthritis), little is known about these new molecules. We aim to characterise these new enzymes by determining what part of the body they are produced in, whether they are associated with specific inflammatory diseases, an ....Novel human tryptases: their potential role in inflammatory diseases of the young and old. We have discovered a number of novel human tryptases, and while other members of this enzyme family have been implicated in the development of inflammatory diseases (including rheumatoid arthritis), little is known about these new molecules. We aim to characterise these new enzymes by determining what part of the body they are produced in, whether they are associated with specific inflammatory diseases, and what target molecules they act on. A better understanding of these factors will increase the chances of finding cures and developing better treatments for important inflammatory diseases of the ageing population.Read moreRead less
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
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
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
