Summary
This proposal, from the Australia and New Zealand multiple sclerosis (MS) Genetics Consortium, aims to interrogate two new genes that it recently identified as predisposing for the development of MS. Both of the genes underlying these findings are also associated with risk of developing other autoimmune diseases such as type 1 diabetes, rheumatoid arthritis and Graves' disease.
Climate Change And Rural Communities: Integrated Study Of Physical And Social Impacts, Health Risks And Adaptive Options

Summary
Rural Australia has begun to experience climate change impacts - which will increase in future. Losses in farm yields, water supplies, property, community morale and family incomes have diverse health effects. We will study the separate and joint effects of climate change and associated extreme events (e.g., bushfires) on selected health outcomes. Using integrative methods, we will clarify the main influences on health risks, their future projections, and how best to intervene to lessen risks.
Long Term Impact, Capacity Gains And Cost-effectiveness Of A Successful Community-wide Child Obesity Prevention Program

Summary
Be Active, Eat Well is the first community-wide obesity prevention project to successfully reduce the weight and waist gain of children. The 'intervention' was to 'boost' community capacity to enable the local organisations to create their own solutions to childhood obesity. This research will continue to assess the project 3 years after that 'boost' to determine the long-term sustainability, impact and cost-effectiveness of this approach to prevent childhood obesity.

Summary
Infertility and recurrent miscarriage affect 60-80 million couples globally, including 15% of couples in Australia. Moreover, 1 in 6 pregnancies is affected by pre-eclampsia, low birth weight or preterm labour. Infertility and other pathologies in pregnancy often result from failure of the maternal tissues to adequately support embryo implantation and development of the placenta, leading to insufficient nutritional support of the developing fetus. We have discovered in mice that disruption in th ....Infertility and recurrent miscarriage affect 60-80 million couples globally, including 15% of couples in Australia. Moreover, 1 in 6 pregnancies is affected by pre-eclampsia, low birth weight or preterm labour. Infertility and other pathologies in pregnancy often result from failure of the maternal tissues to adequately support embryo implantation and development of the placenta, leading to insufficient nutritional support of the developing fetus. We have discovered in mice that disruption in the populations of immune cells called macrophages within the uterine endometrial lining can reduce the receptivity of the endometrum to embryo implantation, and can lead to fetal growth retardation and impaired health after birth. The purpose of this project is to delineate the precise functions of macrophages in interacting with other cells in the endometrium to facilitate attachment of the embryo, its invasion into maternal tissues, and its access to an adequate blood supply as the placenta develops during early pregnancy. We will employ state of the art experimental strategies including genetic models to deplete endometrial macrophage populations in mice, and will then study the implications for changes in endometrial tissue structure and function. Furthermore we will investigate the long term consequences of early macrophage perturbations for the fetus and neonate after birth. This study will improve our understanding of how determinants of macrophage function such as infection and inflammatory conditions, male factors, nutrition and stress can impair fertility and compromise optimal pregnancy outcome in humans.Read moreRead less
Neurobiological Causes Of Overeating In A Rodent Model - Hedonic Versus Homeostatic Control

Summary
Unlimited access to palatable high fat foods, in conjunction with a sedentary life style, has led to increased obesity. Exactly what mechanisms drive over consumption of energy rich foods and override mechanisms that normally regulate body weight? This project will examine feeding behaviour in rats fed palatable high fat diet, to examine when and how they eat. The contribution of brain chemicals implicated in addiction to this eating, and the impact of withdrawal of food will be examined.
