Funding Amount

Summary
Our research will examine the role of a protein known as the receptor-associated protein (RAP) in Alzheimer's disease. We will determine whether the protein contributes to the progression of Alzheimer's disease and we will examine the possiblity that that RAP may be used as a drug to treat the disease. The project could potentially have direct benefit for patients by leading to an effective treatment for dementia associated with Alzheimer's disease.

Summary
Standard advice in the clinical management of headaches is to counsel headache sufferers to avoid any factors that could trigger a headache. There is a compelling logic to this approach but is there a danger that it amounts to being over-protective in the sense that it encourages headache sufferers to 'cocoon' themselves from situations that could give rise to headaches, ultimately resulting in them losing their ability to cope with such situations.

There is a compelling logic to this approach but is there a danger that it amounts to being over-protective in the sense that it encourages headache sufferers to 'cocoon' themselves from situations that could give rise to headaches, ultimately resulting in them losing their ability to cope with such situations. Certainly, avoiding situations that elicit anxiety leads to a sensitisation process whereby the situations elicit greater anxiety. And the converse is true, exposure to anxiety-eliciting situations results in a desensitisation process whereby the situations elicit less anxiety. Whether avoidance or exposure is more appropriate in the management of headache disorders depends on the processes by which sensitivity to trigger factors is gained and lost. Two studies will be completed that test different models of these processes. The expected outcome of these studies is that they will support the theory that stimuli acquire the capacity to elicit headaches as a function of individuals trying to avoid or escape from any factor that they believe could trigger a headache. This sensitisation process can be reversed by prolonged exposure to headache trigger factors. Such results would suggest that the established practice of counselling headache sufferers to avoid triggers is counterproductive as it may lead to a reduction of headaches in the short-term but may also lead to an insidious sensitisation process that ultimately results in an increase in headaches. Given that headaches are so common and associated with such high direct and indirect costs, changes in clinical management arising from these findings could have major benefits to individuals, families and society.Read moreRead less
Investigation Of The Role Of Specific Mucous Associated Bacteria In Children And Young Adults With Crohns Disease

Funding Amount

Summary
The role of bacteria in Crohn's disease is well accepted however to date no conclusive agents have been identified. Recent animal studies have implicated mucus-associated bacteria. We have recently shown that such bacteria, the Helicobacteriaceae, are present in humans and children with Crohn's disease. The aim of this project is to determine in children and young adults the role of these bacteria in IBD thus providing information that could be used to design improved therapies for IBD.
A Genome-wide Linkage Study Of Schizophrenia In A Large Sample From Tamil Nadu, India

Summary
A Study of Schizophrenia in Tamil Nadu, India. The cause of schizophrenia is unknown, but there is good evidence that genes play a role. Geneticists do not fully understand how the disease is inherited, but it is very complex, and several interacting genes as well as environmental factors are probably involved. We have been recruiting families with at least two siblings with schizophrenia from a number of communities-casts in Tamil Nadu. We plan to recruit a total of 400 affected sibling familie ....A Study of Schizophrenia in Tamil Nadu, India. The cause of schizophrenia is unknown, but there is good evidence that genes play a role. Geneticists do not fully understand how the disease is inherited, but it is very complex, and several interacting genes as well as environmental factors are probably involved. We have been recruiting families with at least two siblings with schizophrenia from a number of communities-casts in Tamil Nadu. We plan to recruit a total of 400 affected sibling families, together with 400 trio families (both parents, plus their affected child). A genome-wide scan of the genetic code in all individuals will be conducted to identify chromosomal regions linked to schizophrenia. This is the first necessary step toward identifying schizophrenia susceptibility genes. If one or more genes are discovered, this will greatly improve our understanding of this disease. It will also stimulate the search for similar genes in other samples world-wide, including Australia where schizophrenia costs $2.5 billion annually in terms of treatment and loss of employment. With such a discovery, it may be possible to find better treatments that correct the basic cause of the illness and identify factors that protect against the illness.Read moreRead less
