Summary
Babies born prematurely are more likely to experience problems as a result of being born early with males doing worse than females. The mechanisms causing this difference are unknown. The control of blood flow in the placenta and fetus is essential for normal growth and development. This project will investigate the influence of duration of pregnancy, gender, and exposure to antenatal steroids on pathways that control blood flow in the placenta and the newborn in babies born after prematurely.
Metabolism And Neurotoxicity Of Hemin And Hemin-derived Iron

Summary
Stroke is a leading cause of death and disability in industrialised countries. Much of the brain damage that follows a hemorrhagic stroke is attributable to the presence of free iron which mediates oxidative stress in brain cells. This iron originates from hemin, which in turn is derived from the hemoglobin in extravasated blood cells. The fact that iron is freed from hemin in the post-stroke period makes it an attractive therapeutic target. However, remarkably little is known about the metaboli ....Stroke is a leading cause of death and disability in industrialised countries. Much of the brain damage that follows a hemorrhagic stroke is attributable to the presence of free iron which mediates oxidative stress in brain cells. This iron originates from hemin, which in turn is derived from the hemoglobin in extravasated blood cells. The fact that iron is freed from hemin in the post-stroke period makes it an attractive therapeutic target. However, remarkably little is known about the metabolism of hemin by the different types of brain cells. The present project investigates the metabolism and neurotoxicity of hemin in brain cells and will examine the capacity of potential therapeutic agents to protect brain cells from hemin toxicity. The data obtained from this project will advance our understanding of the uptake and metabolism of hemin by the four main types of brain cell, and the factors that are likely to be involved in the neurotoxicity of hemin-derived iron following hemorrhagic stroke. The study will also provide data concerning the relative effectiveness of potential therapeutic agents, and information concerning the cell types, time points and aspects of hemin metabolism that are most effectively targeted by these agents. Such advances will guide the development of therapeutic approaches that are directed at minimising the brain damage which results from hemin-derived iron in humans.Read moreRead less
Improving Synthetic Methodology To Prepare Pre-clinical Analogues Of Human Insulin

Summary
The glucose regulatory hormone, insulin, remains the only treatment for type I diabetes and up to 30% of type II diabetes, both of which are among the world’s fastest growing chronic diseases today. Because insulin, if taken orally, would be broken down quickly, it has usually been given by injection. This project will develop novel chemical methods for the efficient preparation of novel insulin therapeutics with improved stability and oral bioavailability for prolonged treatment of patients.

Chemical listening devices: Novel sensors targeting the clandestine manufacture and transport of illicit drugs and explosives. There can be no doubt that protecting Australia's borders from the dual threats of terrorism and illicit drugs is of paramount importance to continuation of our well-being and way of life. Our chemical sensors are simple hand-held or remote chemical listening sensors, which will have the ability to sense the presence of characteristic chemical vapours associated with exp ....Chemical listening devices: Novel sensors targeting the clandestine manufacture and transport of illicit drugs and explosives. There can be no doubt that protecting Australia's borders from the dual threats of terrorism and illicit drugs is of paramount importance to continuation of our well-being and way of life. Our chemical sensors are simple hand-held or remote chemical listening sensors, which will have the ability to sense the presence of characteristic chemical vapours associated with explosives and illicit drugs. The simplicity and low cost of the chemical listening allows for installation at key locations -e.g. transport hubs, shipping containers, airports etc as well as placement within clandestine drug laboratories.Read moreRead less
Fighting slime with free radicals - new surface coatings for biofilm remediation. Bacterial biofilms are a major problem in a number of environmental, industrial and medical applications. They cause significant risks to human health and present an enormous economic burden to society. This project aims to develop smart polymeric coatings that will discourage bacterial attachment and ensure greater long term control over biofilm growth. These coatings represent a breakthrough in the field and will ....Fighting slime with free radicals - new surface coatings for biofilm remediation. Bacterial biofilms are a major problem in a number of environmental, industrial and medical applications. They cause significant risks to human health and present an enormous economic burden to society. This project aims to develop smart polymeric coatings that will discourage bacterial attachment and ensure greater long term control over biofilm growth. These coatings represent a breakthrough in the field and will have a profound impact in many areas, including reducing infections related to medical implants and improving the efficiency of marine engineering systems.Read moreRead less
