Summary
One of the greatest challenges facing contemporary gastroenterology is to understand the causes of the inflammatory bowel diseases in order to develop more effective therapies. Although there have been advances in treatment over the last few years, the causes of IBD are still not known. The existence of a genetic predisposition to IBD is now well established, and there is strong evidence that the disease is the result of the interaction of a number of different genes.

Although there have been advances in treatment over the last few years, the causes of IBD are still not known. The existence of a genetic predisposition to IBD is now well established, and there is strong evidence that the disease is the result of the interaction of a number of different genes. To date, two genetic localisations (one on chromosome 16 and a second on chromosome 12) have been confirmed in multicentre studies. We have identified a novel localisation for disease susceptibility on chromosome 12 in the Australian population during the course of a genome scan on 73 multiplex inflammatory bowel disease families. (The importance of this localisation has been confirmed in English and American families.) This localisation is quite separate from that originally described and many genes separate the two localisations. We will refine the new localisation by fine scale mapping in the region of the localisation that we originally identified in pure Crohn's disease families. At this stage, the localisation appears not to be important in families suffering from ulcerative colitis or in families in which both CD and UC occurs (known as mixed families), though this finding will be tested. Using state of the art molecular genetics, we will then identify and characterise the gene involved. The significance of this project lies in the importance of this localisation to the understanding of underlying biochemistry and genetics of a complex disease in which multiple genes are segregating and interacting in, some as yet undefined manner.Read moreRead less

Summary
Migraine is a frequent, debilitating and painful disorder that affects a significant proportion of the population. Using the diagnostic criteria of the international Headache Society, the prevalence of migraine has been estimated to be approximately 12%, with a recent study in the United States showing that migraine affects 4% of children, 6% of men and 18% of women.

Using the diagnostic criteria of the international Headache Society, the prevalence of migraine has been estimated to be approximately 12%, with a recent study in the United States showing that migraine affects 4% of children, 6% of men and 18% of women. The aetiology of migraine is unknown and there are no laboratory based diagnostic tests to identify those who suffer from the disorder. Clinical diagnosis is currently based on patient symptom descriptions, with individual symptoms being shown to vary with age. Migraine is believed to have a genetic basis with specific environmental factors, such as particular foods, hormonal levels and fatigue, being capable of inducing attacks in predisposed individuals. Migraine shows strong familial aggregation with about 50% of those affected, having another close relative also affected with the disorder. At present the number of genes involved in the disorder is unknown and have not been identified. Recent studies in our laboratory have localised two migraine genes, one to chromosome 19 and the other to the X chromosome. More recently we have also found evidence for a third gene on chromosome 1. This study is aimed at fine scale mapping analysis of these three chromosomal regions in order to pinpoint the location of migraine genes. Our ultimate aim is to identify the molecular causes of this disorder. This would have important implications to both the diagnosis and treatment of migraine.Read moreRead less

The Program brings together clinicians, epidemiologists and statisticians in a unique endeavour designed to improve the prevention and treatment of heart attack and stroke.

For the foreseeable future, these conditions will remain leading causes of death and disease in Australia and most other countries in the region. While there are many established treatment and prevention strategies for these conditions there remains great potential for further advances to be made, which might avert very large numbers of premature deaths and serious disabling outcomes. This Program of research seeks to provide new information that will give patients, doctors and policy makers innovative options for the treatment and prevention of heart attack and stroke. The Program will incorporate two main elements: observational studies and randomised controlled trials. The observational studies will establish the precise importance of each of the main causes of cardiovascular diseases (such as diabetes, blood pressure, smoking and cholesterol) at different ages, in different ethnic groups and in different geographic regions. Furthermore, these studies will also define the relative importance of established and novel risk factors for cardiovascular disease, providing important new information about how resources for prevention should be directed. The large-scale trials will provide evidence about the effectiveness and safety of a range of new cardiovascular disease prevention and treatment strategies. The work will build on the team�s very successful approach of evaluating the effects of established interventions in high-risk groups for whom those particular treatments are not currently indicated.The Program will also include studies that address the critical issue of translating health research findings into practice _ in terms of health policy, clinical practice and consumer behaviour. A particular focus involves the application and evaluation of novel Internet technologies for promoting best practice. The methodologies used by the team will ensure that the evidence generated by the Program is as precise and reliable as possible, in order to provide a sound base to guide decisions about changes in health care policy and practice. The research findings will have direct relevance to the healthcare needs of millions of Australians within the next five years, and the impact of the work will be assured by the development of implementation and dissemination plans for each major component of the Program.Read moreRead less

The idea of the picturesque its emergence in the eighteenth century are relatively well known. However, the longer history of the picturesque, through to its use in the present, has not been studied. This Project proposes to describe the key concepts and techniques that constitute the latter history of the picturesque. Against claims that the eighteenth century picturesque was a generic and abstract art, this longer history will show that the picturesque is better understood as an intra-disciplinary relation of architecture and the visual arts. The Project will be of relevance to issues of the historical status of architecture as an art discipline. At a more general level, the Project will be of significance in present issues in the conceptualization of images and objects, including those that arise in virtual environments, issues which first arose in the picturesque.Read moreRead less

This project expects to generate new knowledge in the area of contemporary art using an innovative approach that combines practice-led, artistic research with interdisciplinary decolonial methodologies. Expected outcomes of this project include improved approaches to how the art sector engages with uncomfortable colonial histories. This should provide significant benefits such as enhanced relations between Indigenous and non-Indigenous people by supporting non-Indigenous artists to engage in sensitive truth-telling about Australia’s colonial past.Read moreRead less

Summary
This study will use a unique population isolate from Norfolk Island. We aim to identify genes that play a role in cardiovascular disease risk. Norfolk has a population of ~1200 permanent residents, most of whom are direct descendents of 18th century English Bounty mutineers and Polynesian women. We will undertake gene expression mapping to identify genomic loci that influence cardiovascular disease using samples from this population isolate.

Summary
Studies of the causes and consequences of health outcomes follow large cohorts of individuals for long time periods. A major challenge in analysing data from these studies is that information is often incomplete. Participants rarely complete all waves of data collection, or provide all requested information. Statistical research has led to increased use of a statistical method (multiple imputation) that recovers information from incomplete cases. This project will develop and improve this method
