Summary
Schizophrenia represents a number of clinically distinct syndromes, with a complex mode of inheritance. The delineation of biologically valid subtypes of schizophrenia is necessary to advance our understanding of the genetic basis of these syndromes. This project uses pattern classification techniques to determine subtypes of schizophrenia on the basis of structural brain abnormality across multiple regions, and will examine genetic interactions and differential gene expression associated with t ....Schizophrenia represents a number of clinically distinct syndromes, with a complex mode of inheritance. The delineation of biologically valid subtypes of schizophrenia is necessary to advance our understanding of the genetic basis of these syndromes. This project uses pattern classification techniques to determine subtypes of schizophrenia on the basis of structural brain abnormality across multiple regions, and will examine genetic interactions and differential gene expression associated with these biologically-derived subtypes.Read moreRead less
How Does Exercise Ameliorate Programming Of Metabolic Dysfunction In Offspring Of Obese Mothers?

Funding Amount
$524,121.00
Summary
Obesity is a worldwide disease, reflecting an interaction between our environment (diet, physical activity) and genes. We know that a mother's unhealthy diet can predispose offspring to diabetes, and exercise can improve this, but the underlying mechanisms are poorly understood. Here we will examine how exercise can benefit offspring of obese mothers, and test a drug that mimics the effects of exercise. The proposed research will provide insight into ways of reducing the obesity epidemic.
The Management To Optimise Diabetes And MEtabolic Syndrome Risk Reduction Via Nurse-led Intervention (MODERN) Study

Summary
There is increasing recognition of society’s responsibility to provide effective and sustainable health care to the entire population and not just selected parts. This practical study will test the impact of a nurse-led, multidisciplinary prevention program to reduce the risk of future cardiovascular events in middle-aged individuals at a high risk of developing cardiovascular disease (CVD) living in regional Australia.
Sleep loss and disordered sleep is now recognised as contributing to mortality, chronic disease and economic health burden. The CCRE in Interdisciplinary Sleep Health (CRISH) aims to investigate the biology of sleep, and to prevent and to treat disorders of sleep through a uniquely interdisciplinary approach. The centre will support world-class interventional research aimed to inform clinical practice and alter health policy.

Effects Of Fast Versus Slow Weight Loss On Fat, Muscle And Bone In Postmenopausal Women

Summary
Very low energy diets (VLED) are increasingly used to treat obesity. Of concern is the fact that VLED induce adaptive responses that can inhibit loss of, and promote regain of, abdominal fat while decreasing lean body mass, muscle strength and bone density. This project will therefore determine whether VLEDs could have negative effects on body composition that increase the risk of metabolic disease, sarcopenia or osteoporosis, and if so, what mechanisms are involved.
This proposal is designed to test the protein leverage hypothesis (PLH) in humans: the idea that the level of food consumption in humans, like other animals, is adjusted to maintain a target protein intake. As the prevalence of overweight and obesity increases, with its attendant health problems, the need to identify which dietary components limit rather than exacerbate energy intake is imperative. According to the PLH, the consumption of a diet low in % protein and high in % fat and carbohydrat ....This proposal is designed to test the protein leverage hypothesis (PLH) in humans: the idea that the level of food consumption in humans, like other animals, is adjusted to maintain a target protein intake. As the prevalence of overweight and obesity increases, with its attendant health problems, the need to identify which dietary components limit rather than exacerbate energy intake is imperative. According to the PLH, the consumption of a diet low in % protein and high in % fat and carbohydrate, typical of many Western countries, inevitably requires the ingestion of additional energy to maintain protein intake constant, thus driving weight gain. Conversely, the consumption of a diet that is relatively high in % protein requires the ingestion of lower levels of energy, creating the potential for weight loss. Preliminary experimental and population-level nutritional survey data support the PLH, as does the finding that protein is more satiating than other macronutrients. If, as predicted, small changes in the proportion of protein in diets described in the current study are found to impact on total energy intake there will be significant implications for weight control strategies. Thus, if the PLH is confirmed, public health dietary recommendations and government policy settings for the food industry will need to change. Large-scale intervention studies aimed at demonstrating the longer term impact on body weight will also be required.Read moreRead less
The Nutritional Geometry Of Ageing In A Rodent Model

Funding Amount
$979,269.00
Summary
A central belief in ageing research is that eating fewer calories prolongs life, and that the source of calories (carbohydrate, fat or protein) is irrelevant. However, a critical assessment indicates that this conclusion is premature. We will use recent techniques in nutrition to define for the first time in mammals the relationship between diet and ageing in a normal and a prematurely ageing strain of mice. The project will provide a novel nutritional approach for promoting healthy ageing.
Improving The Cardiometabolic Health Of People With Psychosis: The Physical Health Nurse Consultant Service

Funding Amount
$667,021.00
Summary
People with psychosis have high rates of chronic disease that reduces lifespan by 25 years. The health system struggles to provide adequate care. We developed the Physical Health Nurse Consultant service that provides physical health care coordination and will evaluate whether it improves physical health, consumer experience and cost-effectiveness. Outcomes will directly address policy initiatives to improve physical health service delivery in mental health services.
Do The Mitochondrial Sirtuin Enzymes, SIRT3 And SIRT5, Affect Insulin Action In Skeletal Muscle?

Summary
Metabolic disorders such as obesity, insulin resistance and type 2 diabetes are characterised by inappropriate handling of nutrients. Mitochondria are the primary site for nutrient oxidation in cells. Sirtuins such as SIRT3 and SIRT5 are abundant in mitochondria and may affect mitochondrial function and insulin action in skeletal muscle. Understanding the biochemical pathways involved in energy metabolism in skeletal muscle is crucial in the development of therapies for insulin resistance and ty ....Metabolic disorders such as obesity, insulin resistance and type 2 diabetes are characterised by inappropriate handling of nutrients.

Endocrine signalling from bone cells in the regulation of glucose and energy homeostasis. Osteoporosis, obesity and diabetes are increasingly common, all of which are in urgent need of more effective therapies.

Osteoporosis, obesity and diabetes are increasingly common, all of which are in urgent need of more effective therapies. This project examines powerful neuropeptide signalling pathways that integrate bone homeostasis with whole body energy and glucose balance. Initial studies have defined the efferent hypothalamic pathways of this system and this project will build upon these findings to examine the feedback signals produced by bone cells to regulate adipose and pancreatic function. Exploring this entirely new paradigm of skeletal biology, will reveal novel circulating factors capable of regulating adipose and glucose economies, as well as bone mass, thereby offering potential therapies for these debilitating conditions.Read moreRead less
