Summary
We will use ocular motor technology to investigate motor dysfunction in autism and Asperger's disorder, to advance our understanding of the neurobiological bases of these disorders. This will help clarify whether neural networks are differentially disrupted in these disorders, as our previous clinical research suggests. This dissociation and the subsequent development of an ocular motor clincal screen may improve diagnosis, and potentially treatment, of these devastating conditions.

Summary
While it is well known that autism and Asperger's disorder are associated with social, communicative, and behavioural symptoms, it is less well known that affected individuals also have considerable movement and coordination difficulties. For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running. These skills are very important for success at school; for example, if children are unable to participate in school sports they often feel isol ....While it is well known that autism and Asperger's disorder are associated with social, communicative, and behavioural symptoms, it is less well known that affected individuals also have considerable movement and coordination difficulties. For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running. These skills are very important for success at school; for example, if children are unable to participate in school sports they often feel isolated and rejected from the peer group. Also, hand writing problems have a significant impact on children's academic performance. Our previous research has suggested that there may be particular patterns of motor problems that characterise individuals with autism and Asperger's disorder. Our proposed research aims to use the kinds of 3D motion analysis technology used in the movie industry to capture exactly how people affected by these conditions move and respond to the environment. This study will enable us to highlight particular parts of the brain-motor circuitry that are affected by these disorders and will also enable us to more clearly distinguish how autism is different from Asperger's disorder. Ultimately, it is hoped that our motor investigations will lead to improved assessment and interventions for these disorders.Read moreRead less
Prevalence report by the Australian Advisory Board on Autism Spectrum Disorders (ASD) estimated that 1 child in every 160 children in the 6-12 year-old age group is affected by ASD. There is no cure for ASD and the causes are not understood. We propose that sex hormones may play a role in the development of these disorders. We will test this hypothesis using knockout and transgenic mouse models which have social interaction deficits and brain structure reminiscent of these disorders.

Summary
Autism is charcterised by deficits in social behaviour and communication, and is a cause of major lifelong disability. A novel intervention, Oxytocin, enhances social communication in non-clinical populations. This project will determine whether OT improves social communication deficits characteristic of autism. This project is a critical first step towards treating a core deficit of autism.

Summary
Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development. The first objective of this study is to use 3D-motion analysis to ‘probe’ the underlying brain dysfunction which characterises ADHD-CT. The second objective of this study is to improve our understanding of the link between movement problems, and (a) injury proneness, and (b) social-communicative problems, in children with AD ....Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development.

Summary
Mental health problems of people with developmental disabilities are a substantial public health problem. A large Australian study shows that the problem begins early and persists without intervention. We will evaluate the Stepping Stones Triple P model of parenting early intervention after adding newly developed modules for specific causes of ID. The effectiveness of the program across three states will be evaluated.

Summary
This project will further develop the research opportunities of an internationally unique 15 year follow up study of the mental health of young Australians with ID. 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.

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
Structure and function of heterodimeric amino acid transporters. Recently a new family of amino acid transporters has been identified, the members of which are involved in the delivery of amino acids between cells and tissues. All members display a rather unusual structure in that they require two subunits to be functional. The main aim of this study is to investigate the interaction between large and small subunits.

The study will give insight how membrane proteins form complexes in the membrane and how these interactions affect the function of a complex membrane protein.Read moreRead less
Bioreactors for manufacture of human platelets. Blood cell transfusion is a critical part of medicine that is supported by volunteer donors. Unfortunately, the demand for blood cells for transfusion far outstrips supply and therefore new strategies are required for manufacture of blood cells. This project will lead to the development of technology for manufacture of human platelets from stem cells. The systems devised will be applicable to a broad range of other blood cell types.
Amino acids as nutrients - the molecular basis of amino acid absorption in kidney and intestine. Nutrition is a critical factor for well being and health. This is highlighted by the increase in frequency of type II diabetes and the obesity problem that all societies with a western diet face.

Nutrition is a critical factor for well being and health. This is highlighted by the increase in frequency of type II diabetes and the obesity problem that all societies with a western diet face. Most studies in nutrition focus on fat and carbohydrates because of their direct involvement in obesity and diabetes. Proteins and the resulting peptides and amino acids, however, form 10-15% of our nutrition. At a time where protein-rich diets are recommended to fight obesity and diabetes, it is important to understand the basis of protein absorption and metabolism. This project investigates the mechanism and mediators of amino acid absorption in kidney and intestine. Read moreRead less
