An Integrated Approach Towards Development of Highly Specific Chemotherapeutics. Many diseases are caused or can be treated by modifying the activities of particular enzymes. Molecules that affect enzymatic activities have potential as therapeutic agents. A successful approach to the discovery of new drug molecules is to design them based on very detailed knowledge of how the target enzyme works. In this project, a highly motivated team of scientists will use state of the art instruments and the ....An Integrated Approach Towards Development of Highly Specific Chemotherapeutics. Many diseases are caused or can be treated by modifying the activities of particular enzymes. Molecules that affect enzymatic activities have potential as therapeutic agents. A successful approach to the discovery of new drug molecules is to design them based on very detailed knowledge of how the target enzyme works. In this project, a highly motivated team of scientists will use state of the art instruments and their combined creativity to understand the intimate details of how one large group of enzymes work. The enzymes selected are the bimetallic hydrolases, many of which are associated with disorders including osteoporosis, mental illnesses, cystic fibrosis and various types of cancer.Read moreRead less
Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobili ....Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobility of water molecules is a potent indicator of the microscopic structure of the cartilage scaffold. We will use this fundamental biophysical relationship to measure the internal architecture of collagen fibres; observe the changes effected by mechanical load; and distinguish between healthy and osteoarthritic cartilage.

Structure-based design of anti-osteoporotic drug leads: an integrated approach. One of the major consequences of Australia's aging population is that age-related diseases, such as osteoporosis, are increasing. Apart from the significant human suffering caused by this disease, there is an immense financial burden on the community, patients and their families. Current treatments for osteoporosis are often ineffective and also have major side-effects. An enzyme has been identified which plays a cru ....Structure-based design of anti-osteoporotic drug leads: an integrated approach. One of the major consequences of Australia's aging population is that age-related diseases, such as osteoporosis, are increasing. Apart from the significant human suffering caused by this disease, there is an immense financial burden on the community, patients and their families. Current treatments for osteoporosis are often ineffective and also have major side-effects. An enzyme has been identified which plays a crucial role in the progression of this disease by increasing the rate of bone-thinning. We will make compounds to slow down this enzyme. This project will provide the basis for the future development of new and improved drugs to treat osteoporosis.Read moreRead less
Graded Biomaterial for Articular Cartilage Replacement. Osteoarthritis is a major health and economical burden on the Australian community which can be addressed in part by providing a viable option for effective clinical treatment. 34% of people over the age of 50 suffer from osteoarthritis, predominantly the knee. The development of a biomaterial to enable repair of articular cartilage through minor surgical procedures will release resources at point of care. Current biomaterial options are st ....Graded Biomaterial for Articular Cartilage Replacement. Osteoarthritis is a major health and economical burden on the Australian community which can be addressed in part by providing a viable option for effective clinical treatment. 34% of people over the age of 50 suffer from osteoarthritis, predominantly the knee. The development of a biomaterial to enable repair of articular cartilage through minor surgical procedures will release resources at point of care. Current biomaterial options are still in infancy and an Australian based product would benefit the Australian economy as well as Australia's international standing within the biomaterials community.Read moreRead less
DEVELOPMENT OF A NOVEL BIOMATERIAL FOR BONE TISSUE ENGINEERING. Tissue engineering of bone is emerging as a viable therapy for treating large defects in load-bearing bone. We wish to develop methods for combining novel heparan sulphate molecules (known to deliver growth factors to cell surfaces and thereby cause changes in bone cell phenotype) with load-bearing, macro-porous, biodegradable mineral/polymer biomaterials. Through the study of release profiles, protein adsorption and cell responses ....DEVELOPMENT OF A NOVEL BIOMATERIAL FOR BONE TISSUE ENGINEERING.

We wish to develop methods for combining novel heparan sulphate molecules (known to deliver growth factors to cell surfaces and thereby cause changes in bone cell phenotype) with load-bearing, macro-porous, biodegradable mineral/polymer biomaterials. Through the study of release profiles, protein adsorption and cell responses to these derivatised biomaterials, a novel approach to bone replacement materials can be developed.Read moreRead less
Material structure and properties of mineralised tissue: An integrated micro and nano level investigation. Bone material properties have a direct influence on disorders of the skeleton, such as osteoporotic bone fragility fractures and osteoarthritis. It has been estimated that the direct and indirect cost of all fragility fractures and arthritis is over $20 billion per annum. The impact of this will be far-reaching with the social benefits ranging from earlier and more accurate diagnoses, to t ....Material structure and properties of mineralised tissue: An integrated micro and nano level investigation. Bone material properties have a direct influence on disorders of the skeleton, such as osteoporotic bone fragility fractures and osteoarthritis. It has been estimated that the direct and indirect cost of all fragility fractures and arthritis is over $20 billion per annum. The impact of this will be far-reaching with the social benefits ranging from earlier and more accurate diagnoses, to the development of preventative strategies to delay the onset of musculoskeletal disorders. These developments will translate into exciting commercial opportunities and overall economic growth and sustainability.Read moreRead less
