Summary
Repetitive Transcranial Magnetic Stimulation (rTMS) is the direct stimulation of the brain by using high field magnetic pulses. It is a new technique that has been demonstrated to have some potential as a treatment of depressive illness and possibly other neuropsychiatric disorders. At this early stage of its investigation, the parameters of stimulation that are most likely to be therapeutic, and its mechanisms of action, are not known.

It is a new technique that has been demonstrated to have some potential as a treatment of depressive illness and possibly other neuropsychiatric disorders. At this early stage of its investigation, the parameters of stimulation that are most likely to be therapeutic, and its mechanisms of action, are not known. Published studies vary in the frequency, duration and extent of stimulation, with no firm guidelines about optimal parameters. Empirical study of the relative effects of stimulation at different frequencies, at different numbers of stimuli and for different durations is therefore important for the future development of this treatment. Such an investigation is best carried out in an animal model of depression for both ethical and practical reasons, as such studies in patients would possibly take many years and be extremely difficult to conduct. We propose such a study in rat models of depression which have demonstrated validity and utility in drug research. Rat models have a long track record in developing psychiatric treatments and are cost-effective and of proven value. We also plan to investigate the neuroanatomy of the immediate-early genes induced by TMS and compare it with electroconvulsive shock (ECS) and a tricyclic antidepressant, two established treatments of depression. The results will have implications for future human studies in guiding us toward the optimal parameters for therapeutic effects. They will also enhance our understanding of the mechanism of action of TMS in depression.Read moreRead less

Summary
Australia has one of the world's most rapidly ageing populations. It is estimated that in 30 years time over 30% of the population will be over 65; many will suffer from a debilitating, age-related disease. The diseases of ageing represent one of the major health challenges this century. Despite their increasing incidence, our understanding of the underlying causes is limited.

It is estimated that in 30 years time over 30% of the population will be over 65; many will suffer from a debilitating, age-related disease. The diseases of ageing represent one of the major health challenges this century. Despite their increasing incidence, our understanding of the underlying causes is limited. A common feature is the accumulation of damaged proteins in cells and tissues. Damaged proteins are usually broken down by the cells and replaced, but in many age-related diseases this process fails. The most common source of protein damage is attack by oxygen-derived free radicals. These are by-products of our body's need for oxygen and can originate from atmospheric pollutants. Oxygen rusts metal, makes fat go rancid and can cause irreparable damage to proteins and other biological molecules. Free radical damage contributes to the development of many age-related diseases such as atherosclerosis and neurodegenerative diseases such as Alzheimer's disease. The accumulation of damaged proteins can cause cell death. Our knowledge of the mechanisms by which cells remove proteins damaged by oxygen and the reasons for their accumulation is limited. In this project we will use a novel technique we have developed to generate oxidised proteins in ageing cells. We will identify cellular mechanisms required for the efficient removal of damaged proteins and those mechanisms which fail in ageing cells. We will focus on a group of proteins which protect damaged proteins from aggregating and accumulating and we will examine how we can prevent the accumulation of oxidised proteins by stimulating the body s defence mechanisms. Since the population of Australia is ageing, diseases of ageing are going to consume an increasing amount of the national health budget. A better knowledge of these cellular mechanisms will allow us to design effective prevention and treatment strategies which are at present lacking.Read moreRead less

Summary
Cardiovascular disease (heart attack and stroke) are leading causes of death and illness in adults in Australia. The changes in blood vessels that lead to these conditions begin before birth. This project investigates the factors that contribute to these early changes from birth onwards, and will facilitate development of targeted prevention in high-risk groups to reduce cardiovascular disease in later life.
Peopling educational policy: realising the new Australian English and mathematics curricula. Implementation of Australian curricula in English and mathematics provides an opportunity for school systems to re-examine practice. This project will identify resources and teacher learning opportunities needed to facilitate implementation of these curricula and use findings to develop interventions identified as likely to optimise implementation.

This project aims to develop discipline-specific pedagogies in senior physics, chemistry and biology to improve disadvantaged students’ engagement and achievement. Many students from disadvantaged backgrounds fail to develop the linguistic precision and symbolic representational dexterity needed to comprehend and communicate senior school science concepts. These pedagogies will ‘infuse’ multiliteracies in senior school science to improve access to science-based pathways for these students, and enable them to understand progressively more complex scientific concepts and demonstrate this in examinations. This project is expected to improve student retention, arrest declining enrolments in senior school science, and increase young people working in science.Read moreRead less

Laboratory classes are a critical part of science and engineering degree programs, but there has been little research into what actually takes place within them. Remote laboratories, in which students control equipment via the internet, are one potential solution for accommodating rising numbers of students, but the interfaces must be developed to effectively support student learning. This project will investigate how students interact with equipment, each other, and with laboratory demonstrators in order to determine the crucial components of effective laboratory learning experiences. It will identify and characterise the interactions of students in laboratory classes, and develop mechanisms to support these interactions remotely.Read moreRead less
