We have shown that this group has 2-3 times the risk of suffering serious emotional and behavioural problems that are an added heavy burden on the individual, their family and carers and the community. These problems often are not recognised but are as common as schizophrenia in the community. The study will continue to use a combination of questionnaire survey and in depth interviews of the young adults and their families or carers to track the course of their mental health. The study commenced in 1990 with nearly 1000 young people with ID aged 4-18 years and their progress has been reviewed every 2-3 years in over 75% of the original group. During the next 5 years we plan to follow their mental health during the critical stage of young adult life. During this time there is the greatest risk of mental illnesses such as depression and schizophrenia and the stresses of adjusting to new daily occupations, independent living or residential care and social contact away from the family. We will be able to study the specific emotional and behavioural problems faced by young adults with the main known causes of ID such as Down, Fragile X, Prader Willi and William Syndromes, as well as those who have autism. The great benefit of a long term follow up study is that it allows us to study the links between earlier family environmental, psychological and biological factors and subsequent mental health problems. We can also demonstrate the impact that mental illness in a young person with ID has on the family and parental mental health. The findings have implications for better diagnosis, improved care and management, early intervention and prevention of these common severe and under recognized mental health problems in this disadvantaged group of young Australians and their families and carers.Read moreRead less
Chromosomes are structures that carry genes in all our cells. Every human cell has 46 chromosomes. In the nucleus of eukaryotic cells, DNA is highly folded and compacted with specific proteins into a dynamic polymer called chromatin. Gene expression, chromosome division, DNA replication, and repair all act, not on DNA alone, but on this chromatin template.

Every human cell has 46 chromosomes. In the nucleus of eukaryotic cells, DNA is highly folded and compacted with specific proteins into a dynamic polymer called chromatin. Gene expression, chromosome division, DNA replication, and repair all act, not on DNA alone, but on this chromatin template. The discovery that enzymes can (re)organise chromatin into accessible and inaccessible configurations revealed mechanisms that considerably extend the information potential of the genetic code. In addition, it is now established that chromatin structural features can influence gene expression. In vitro studies support a model in which chromatin functions as a barrier for the access to DNA. Therefore this organization has to be tighly regulated and dynamic to allow the protein-DNA interactions critical for nuclear functions. Importantly genome organisation provides in addition to genetic information another layer of information, so called epigenetic, which by definition means that it is stably inherited throughout cellular divisions, yet it is not encoded genetically. Thus each cell type will display a specific epigenome. We have recently constructed small human minichromosomes, which are much easier to study than the much larger normal chromosomes. The present project proposes to define the epigenetic feature across an entire human chromosome using our minichhromosomes as working models. The outcome will be a significant gain in our knowledge on the processes underlying epigenetic regulation, the organisation of specialised chromatin domain, and behaviour of the chromosomes.Read moreRead less

Summary
Tobacco smoking remains the most common preventable cause of death and illness in Australia today. Smoking cessation programs are some of the most effective and cost effective strategies that can be undertaken in health care settings, including general practice. This project will test a new approach to supporting smoking cessation in general practice. This involves the practice nurse, GP and Quitline working in partnership to provide a flexible program of suport to meet the needs of smokers.
The Role And Inheritance Of Constitutional Epimutations In Early-onset Colorectal Cancer.

Summary
Traditionally familial cancers are thought to be caused by spelling mistakes within the genetic code of cancer prevention genes. Our group has found that chemical attachments to one gene (MLH1) stops it working, even where there is no spelling mistake, and that those chemical changes can be inherited in families with bowel cancer. We will determine how frequently this type of defect occurs in bowel cancer patients, how and why it arises, and if other cancer genes are similarly affected.

Summary
This project will provide evidence on how best to use the efforts of Australian GPs to obtain better outcomes in patients aged 65+ years who suffer from chronic diseases such as diabetes, heart disease and high blood pressure, asthma and emphysema, seizures and stomach disorders. It will also examine the best way that GP visits can promote healthier ageing in all older seniors, aged 75+ years.

It will also examine the best way that GP visits can promote healthier ageing in all older seniors, aged 75+ years. For each disease and in older seniors, the study will be able to detect which of the following factors are the most important for better patient health: (i) seeing a GP more times, (ii) seeing a GP at more even intervals, (iii) seeing the same GP, or (iv) seeing a GP with a lot of experience in chronic diseases. Separate investigations will be made in older people living in hostels and nursing homes, because their needs may be different. The study will also evaluate the benefits of a major change that occurred to Medicare in 1999, when GPs were paid to perform health assessments and to prepare health plans (with other health workers) for patients with chronic health problems. The results will enable this important initiative to be further improved. The study will use a unique and new Australian research facility, which has brought together health data on the entire population of WA from both the State and Commonwealth levels, including information on Medicare use, pharmaceuticals, hospital stays and deaths. The facility works in such a way as to preserve patient and GP privacy. A strong feature of this research will be the degree of involvement of a representative and voluntary group of older Australian patients who attend GP clinics, and the GPs themselves, in advising the researchers on what's important to consumers and GPs.Read moreRead less

Summary
This is a population-based longitudinal investigation of the early life host-environment interactions that influence development of the immune system, and the risk of allergic disease. Importantly, this is one of the first studies designed to examine epigenetic programming of the infant immune system in the population setting. Thus we will be able to conduct robust tests of several critical hypotheses that will inform the prevention of allergic disease.

Summary
Genital Chlamydia infections are the most common sexually transmitted infection in Australia with annual health costs of 90-160 million dollars. Infection rates in 15-29 olds are increasing at 15-20% per year in both females and males. Antibiotics are currently the treatment of choice, however antibiotic resistance is increasing and most infections are asymptomatic and not treated in the absence of screening programs. This project aims to develop a Chlamydia vaccine tailored to protect males .

Summary
The transition from mosquitoes, ticks, or other invertebrate vectors to the human hosts represents a crucial step in the successful establishment of arthropod borne viruses (arboviruses).

The incidence of arbovirus infections such as dengue virus, West Nile virus, Ross River virus is increasing at an alarming rate in various parts of the world. In addition, the emergence of new viruses resulting in significant mortality in the population is of utmost concern. Vaccines for many of these viruses remain elusive. One factor that contributes to this is the ability of viruses to develop ingenious strategies to avoid or suppress the host defence systems, which enable its successful establishment in the host. Understanding how viruses evade-suppress host defence machinery will certainly enhance and improve our approaches to fight them. For the first time internationally we have discovered a new and novel pathway employed by arboviruses to suppress antiviral immune responses in the host. We have discovered that naturally occurring carbohydrates on viruses derived from mosquito cells, would influence these virus s ability to evade-suppress host antiviral proteins such as interferons. This may be a general effect of arboviruses or may even extend to other viruses , which include a number of deadly pathogens (HIV, Influenza). This research has the potential to significantly expand our understanding of how these viruses establish infection and cause disease. Also this discovery has broader implications for understanding inflammatory processes and their regulation.Read moreRead less
