Disease caused by the bacterium Clostridium difficile are a significant food production animal and public health problem in many countries. Specific animal and human public health resources have been allocated in many countries in efforts to mitigate the growing epidemics. The study proposed in this application presents a significant opportunity to learn about the virulence factors of animal strains of this bacterium about which very little is known. This project will lead to rationally designed preventative and treatment strategies that apply to both animals and humans, thereby impeding epidemics caused by C. difficile in Australia.Read moreRead less
The development and evaluation of a new therapy for the prevention and treatment of bacterial infections in hospitals. The technology used in this project will enable products to be developed from the Australian dairy industry which may safely provide protection and treatment for diarrhoea acquired in hospitals for which there are few effective options. The product will be cost effective and can be used as a public health tool to control outbreaks in those most susceptible to severe disease.
Fundamental theoretical and experimental investigation of cartilage mechanics. Arthritis and chronic joint symptoms are one of the leading causes of disability in the community, yet a fundamental understanding of joint mechanics has yet to be realised. The aim of this project is to develop a new state-of-the-art mathematical model describing cartilage behaviour in humans. The model will explain how activities like walking maintain healthy cartilage by transferring growth factors through the tiss ....Fundamental theoretical and experimental investigation of cartilage mechanics. Arthritis and chronic joint symptoms are one of the leading causes of disability in the community, yet a fundamental understanding of joint mechanics has yet to be realised. The aim of this project is to develop a new state-of-the-art mathematical model describing cartilage behaviour in humans. The model will explain how activities like walking maintain healthy cartilage by transferring growth factors through the tissue, and quantitatively explain how wear is minimised in cartilage through weeping lubrication. This model will progress our understanding of cartilage mechanics in health and disease, and so help Australians age well and productively.Read moreRead less
Reg growth factors in gastric regeneration and disease. This project will obtain a more detailed knowledge of the role that growth factors play in helping the lining of the stomach repair itself after damage caused by disease. Growth factors may also play a role in causing stomach cancer. To do this we will examine the expression of growth factors in number of stomach diseases and cancer and assay the ability of growth factors to promote the growth of stomach cells.
This work is that it will co ....Reg growth factors in gastric regeneration and disease. This project will obtain a more detailed knowledge of the role that growth factors play in helping the lining of the stomach repair itself after damage caused by disease. Growth factors may also play a role in causing stomach cancer. To do this we will examine the expression of growth factors in number of stomach diseases and cancer and assay the ability of growth factors to promote the growth of stomach cells.
This work is that it will contribute to our knowledge of how cell growth in the stomach is controlled under normal circumstances and in the very common pathological conditions of tissue damage, inflammation and cancer. It may also help us understand how inflammation can in some circumstances lead to cancer.Read moreRead less
Central pathways regulating visceral pain. This project aims to investigate the neural pathways within the spinal cord and brain processing colorectal pain perception. The project aims to identify the spinal cord neurons relaying colorectal signalling into the brain and the influence of descending modulation from the brainstem upon these pathways. The outcomes will greatly benefit fundamental understanding of the central pathways processing visceral pain.

Inflammatory bowel disease affecting millions of people world-wide and results in a significant economic burden ($100M in Australia per year). In collaboration with Australia’s largest biotechnology company, CSL, we will use a novel approach to discover the causes of inflammatory bowel disease. This work will lead to the development of new animal models of inflammatory bowel disease that are vital for analysing the disease and testing treatment options. In addition, this work may lead to new approaches to treating this disease. The project will result in a greater understanding of inflammatory bowel disease, the training of highly skilled scientists and potentially lead to economically valuable knowledge.Read moreRead less
Wiring the gut's nervous system: formation and maturation of synapses. This project aims to determine how nerve circuits controlling intestinal functions develop; specifically how communication between specific nerve cells is established once they appear in the embryonic gut. It will fill a major hole in existing knowledge of mechanisms regulating the development of normal digestive behaviours.

Natural Therapeutic Products from Shark Bile. Scymnol and its sulfate are natural therapeutic products from shark bile with highly potent anti-oxidant and liver-protective activities. The Industry Partner and Macrides have co-patented the synthesis of scymnol to avoid using scarce natural resources. However, unresolved problems in scale-up of production have prevented them from supplying the growing demands of cosmetic and health food companies. Our research group has recently developed a potent ....Natural Therapeutic Products from Shark Bile. Scymnol and its sulfate are natural therapeutic products from shark bile with highly potent anti-oxidant and liver-protective activities. The Industry Partner and Macrides have co-patented the synthesis of scymnol to avoid using scarce natural resources. However, unresolved problems in scale-up of production have prevented them from supplying the growing demands of cosmetic and health food companies. Our research group has recently developed a potential synthetic route for scymnol sulfate. The present project aims to develop a commercially-viable scale-up of this synthesis for manufacturing scymnol and scymnol sulfate to solve current supply problems; and to provide essential safety information for their appropriate use; and evaluate potential new therapeutic uses.Read moreRead less
Electrical activity in early enteric neuron development. Intestinal movements and secretion are critical to the good health and nutrition of both humans and animals. These functions are regulated by a large nervous system contained within the intestinal wall, the enteric nervous system. This project will identify how enteric nerve cells develop and how their behaviour influences the development of other enteric nerve cells.

These functions are regulated by a large nervous system contained within the intestinal wall, the enteric nervous system. This project will identify how enteric nerve cells develop and how their behaviour influences the development of other enteric nerve cells. This is will provide an important base for more applied research aimed at developing treatments for diseases like chronic constipation and irritable bowel syndrome. It will also contribute to the growing knowledge about how epigenetic factors can modify genetically programmed development within the nervous system.Read moreRead less
