Summary
Cataract is the major cause of blindness worldwide. At present the only treatment for cataract, is surgery. This, however, is associated with complications (e.g. posterior capsule opacification), is expensive (a major component of the Health budget) and cannot keep pace with the incidence of cataract in developing nations. In addition, due to the greying of the community , this problem will be of increasing importance in the future. For prevention, we need to understand why cataract develops.

Summary
Regular participation in physical activity is associated with a range of physical and mental health benefits in adults, including reduced risk for cardiovascular disease, non-insulin dependent diabetes, overweight, hypertension, osteoporosis, some cancers and anxiety and depression. Regular participation in physical activity also improves the ability to meet the demands of work and to engage in leisure activities. Approximately half of all adult Australians are insufficiently active to gain the ....Regular participation in physical activity is associated with a range of physical and mental health benefits in adults, including reduced risk for cardiovascular disease, non-insulin dependent diabetes, overweight, hypertension, osteoporosis, some cancers and anxiety and depression. Regular participation in physical activity also improves the ability to meet the demands of work and to engage in leisure activities. Approximately half of all adult Australians are insufficiently active to gain the many health benefits associated with participation in regular physical activity. Modification of the physical environment is one avenue through which the prevalence of physcial activity participation might be increased. More specifically, there has been considerable speculation about the role of public transportation systems in increasing the proportion of adults who are adequately physically active, but no empirical evidence is available. This study will employ a quasi-experimental design to determine if the extension of the Sydney Light Rail System to Lilyfield results in an increase in the prevalence of physical activity (primarily walking) in the affected area, in comparison with a demographically similar area which is not affected by the light rail extension.Read moreRead less

Summary
Cataract is the most common cause of blindness worldwide, The cause of cataract is currently unknown and the only treatment available at present is surgery. This represents a huge burden on the Health budgets of all developed nations, including Australia. It has been estimated that if a treatment could be developed that simply delayed the onset of cataract by 10 years, the need for surgery would be halved. The savings to the Health budget in the USA alone would be approximately $2 billion (US). ....Cataract is the most common cause of blindness worldwide, The cause of cataract is currently unknown and the only treatment available at present is surgery. This represents a huge burden on the Health budgets of all developed nations, including Australia. It has been estimated that if a treatment could be developed that simply delayed the onset of cataract by 10 years, the need for surgery would be halved. The savings to the Health budget in the USA alone would be approximately $2 billion (US). We believe, on the basis of our previous research, that human lens UV filter compounds play a major role in the protein modification that is the hallmark of age-related cataract and indeed may be the key factor in precipitating cataract. This proposal seeks to confirm this hypothesis. If this theory is confirmed, it opens the door to pharmacological intervention for cataract by, for example, treating patients (or possibly all people in middle age) with drugs that inhibit the synthesis of the UV filter compounds.Read moreRead less

Summary
We have identified proteins located in bacteria that are responsible for growth and the transport of essential nutrients. We will use a combination of bacterial genetics, protein biochemistry and immunological techniques to fully characterize these proteins. This strategic knowledge has direct implications for vaccine development and National security, since similar species of bacteria were amongst the first biological weapons.

Summary
Osteoporosis is a largely preventable disease yet 1 in 10 Australians have osteoporosis. Every year >64,000 osteoporotic fractures occur, which is one every 8.1 minutes and women are three times as likely to have the disease than men. The Bone and Calcium Research Group at the University of Western Australia, is studying how to prevent osteoporosis in elderly women.

Every year >64,000 osteoporotic fractures occur, which is one every 8.1 minutes and women are three times as likely to have the disease than men. The Bone and Calcium Research Group at the University of Western Australia, is studying how to prevent osteoporosis in elderly women. This study is called the Calcium Intake Fracture Outcome Study or CAIFOS. During 1998, 1,500 women were recruited to study whether a daily calcium supplement for 5 years helps to prevent fractures compared to a diet without a supplement. To do this only half of the women were given calcium supplements and the other half were given matched placebo tablets. Each year the study participants are reviewed and asked whether or not they have broken any bones and have other measurements to monitor their bone health and overall health. The subjects are entering their last year of treatment and will finish the study during 2003. At this appointment all subjects will undergo the same series of measurements that they had at the beginning of the study to determine whether or not they have fractured any bones, improved their bone mass and overall health during the treatment stage. The main outcome of the study is to determine whether calcium is useful as a supplement to prevent osteoporotic fracture in elderly women. If this study finds that fewer women fractured in the calcium treated group compared to the non treated group, given that both groups were similar to begin with, we can say that supplementation with calcium prevents fractures. Thus, public health messages about preventing osteoporosis will be able to direct the community to take supplements to prevent a disease that creates pain and disability in later life. The advantage of this study is that it is studying other aspects of these women health, so we can determine whether the calcium is safe to use and improves people's quality of life.Read moreRead less

Summary
Poor growth before birth or intrauterine growth restriction (IUGR), as indicated by being light, short or thin for stage of pregnancy, greatly increases the risk of illness and death before and after birth and in infancy. IUGR has increased risks of asphyxia, poor glucose control, hypothermia, respiratory difficulties, neurological problems and poor immune function, many of which persist. IUGR is one of the most common clinical problems in obstetrics and neonatology, with ~6% of infants born IUG ....Poor growth before birth or intrauterine growth restriction (IUGR), as indicated by being light, short or thin for stage of pregnancy, greatly increases the risk of illness and death before and after birth and in infancy. IUGR has increased risks of asphyxia, poor glucose control, hypothermia, respiratory difficulties, neurological problems and poor immune function, many of which persist. IUGR is one of the most common clinical problems in obstetrics and neonatology, with ~6% of infants born IUGR in Australia in non-Aboriginal communities and between 7 to 17% in Aboriginal communities. Despite these adverse consequences for health of the individual throughout life, we do not currently have any effective therapies to treat IUGR. Small infants are mostly a result of an inadequate supply of oxygen and nutrients before birth, due to an impaired capacity of the mother to acquire these for the placenta to deliver them to the growing fetus or due to poor functioning of the placenta itself. This intrauterine malnutrition not only slows growth, but impairs the development of a range of body functions leading to the increased risk of illness and death in IUGR. Therapies to be used before birth to treat IUGR need to either restore supply of oxygen and nutrients or to promote growth and functional development. We have discovered that administration of a major growth promoting hormone, insulin-like growth factor-I (IGF-I), to the IUGR fetus, which has low levels of IGF-I, increases its growth. This project will therefore determine if directly giving this hormone in the IUGR fetus will restore development as well as growth before birth, improving function and hence survival and health after birth. If successful, the first effective approach to the antenatal treatment of IUGR will have been identified and would provide the essential knowledge for the design of a range of therapies to best restore the abundance of IGF within the IUGR fetus to improve perinatal and later outcomes.Read moreRead less
