This will involve investigating new targets for pharmacological therapies, evaluating whether common co-morbid disease states such as diabetes alter the efficacy of these therapies and investigating the role of stem-cell therapy in this setting. The Program will also evaluate the contribution of non-heart failure drugs to the burden of heart failure, determine the impact of rurality on prescribing for this condition and explore systems of optimising delivery of best practice to the community. This research formalises the existing collaborative efforts of a team of investigators that span all aspects of research into the therapeutics of CHF from basic laboratory research to evaluation of patients in clinical trials and public health translational aspects of this condition. The Chief Investigators and Principal Investigators have an existing successful research collaboration which will be greatly expanded via Program.Read moreRead less

Summary
Aerosol therapy is the most effective form of treatment for children with respiratory diseases such as asthma. While optimising aerosol delivery systems has an important role in increasing the efficacy of asthma therapy, ensuring patient compliance is often the most difficult part of the clinician's role, particularly in the paediatric age group. An innovative small volume spacer device (Funhaler) developed by a West Australian company (InfaMed, Ltd) may help overcome this problem.

While optimising aerosol delivery systems has an important role in increasing the efficacy of asthma therapy, ensuring patient compliance is often the most difficult part of the clinician's role, particularly in the paediatric age group. An innovative small volume spacer device (Funhaler) developed by a West Australian company (InfaMed, Ltd) may help overcome this problem. The Funhaler incorporates a spinning toy attached to the outside of the spacer. The toy is activated when the patient breathes through the spacer. The device has been designed to encourage children to co-operate when their asthma therapy is being delivered. The Funhaler is currently in the late development stage. We propose, firstly, to carry out in vitro assessments of drug delivery from the Funhaler compared to the two most widely available small volume spacers: the Aerochamber Plus (Trudell, Canada) and the Breath-A-Tech (Scott-Dibben, Australia). These assessments will be carried out to meet the standards of regulatory bodies worldwide (including the FDA). Secondly, we propose to perform extensive in vivo studie: filter studies to assess drug delivery to the patient; deposition studies to measure drug deposition in the lungs; and a pilot clinical trial to assess the efficacy of the device during medium to long-term use in children aged 2-8 years.Read moreRead less

Summary
Friedreich ataxia (FRDA) is an inherited disorder of the nervous system and muscles. The genetic defect that causes FRDA results in reduced levels of an essential protein termed frataxin. By using information and resources generated as part of the Human Genome Project we have developed new techniques to study human gene expression in cellular and animal systems. Our aim is to identify and develop new pharmacological approaches for the restoration of FRDA gene expression and the therapy of FRDA.
Optimising The Efficiency Of Enforcement In Commercial Fisheries

Summary
The cost of enforcement in most fisheries is substantial. There has been little research on the effectiveness of enforcement measures or the investigation of alternate enforcement strategies. An understanding of the fisher’s perception of the enforcement program, particularly the perceived level of inspections, and how they will respond to changes in enforcement is required to more effectively and efficiently maintain compliance with the regulations.

There has been little research on the effectiveness of enforcement measures or the investigation of alternate enforcement strategies. An understanding of the fisher’s perception of the enforcement program, particularly the perceived level of inspections, and how they will respond to changes in enforcement is required to more effectively and efficiently maintain compliance with the regulations.
Similarly the relationship between the extent of enforcement effort and the level of compliance is not understood for most fisheries. If the rate of compliance is not overly sensitive to the amount or type of enforcement it may be possible to reduce some elements of the enforcement effort and cost while maintaining an acceptable level of compliance. On the other hand if the rate of compliance is highly sensitive to the amount of enforcement effort it will be possible to determine the amount of effort required to obtain the required level of compliance.
The true nature and extent of non-compliance is required to better direct enforcement effort. Spatial and temporal patterns of non-compliance need to be investigated. A better understanding of the motivation for non-compliance, whether the incentive is financial or otherwise, will be gained by comparing expected gains against the likely penalties and probability of detection. This will enable the effectiveness of penalties as a deterrent to be assessed. This information is needed in a form that will enable managers responsible for enforcement activities to explore the effect of the location, timing and type of enforcement activity on the level of compliance. Objectives: 1. Estimate the level of non-compliance in the Western Australian rock lobster industry. 2. Determine factors such as seasonal, regional and factory, which may affect the level of non-compliance in order to better target the timing of enforcement effort. 3. Develop relationships between enforcement and compliance with the regulations to enable an assessment of increasing or decreasing the level of enforcement on the level of compliance. 4. Determine the reasons and motivations for the non-compliance of commercial fishers with the regulations in terms of the expected gains versus the probability of detection. 5. Ascertain the perceptions of the fishing regulations and enforcement measures including the perceived probability of detection for commercial fishers. 6. Ascertain whether commercial fishers are aware of the full extent and frequency of inspections. Read moreRead less

We have discovered a new cytokine that we have named macrophage inhibitory cytokine 1 (MIC-1). It belongs to a very important family of proteins that are involved in wound healing, development and inflammation. Our data thus far suggests that MIC-1 is an anti-inflammatory factor that is of particular relevance in rheumatoid arthritis. We wish to determine the relationship between the amount of this cytokine in the joint and the blood and the activity of rheumatoid arthritis. To better understand the actions of this molecule, we also want to study the factors that regulate the production of MIC-1 from human blood cells. Finally, to assess whether MIC-1 is useful for the treatment of rheumatoid arthritis, we will use gene therapy approaches to develop animals that produce increased amounts of MIC-1 and determine whether this prevents or mitigates the development of rheumatoid arthritis.Read moreRead less

Summary
Growth hormone (GH) is essential for body growth and development. In adult life, it plays a key role in regulating the ratio of body fat to muscle, thus influencing health. Disruption of GH action decreases muscle mass and increases body fat. These changes lead to reduced muscle strength and fitness, and increase the risk of diabetes, hypertension and cardiovascular mortality.

In adult life, it plays a key role in regulating the ratio of body fat to muscle, thus influencing health. Disruption of GH action decreases muscle mass and increases body fat. These changes lead to reduced muscle strength and fitness, and increase the risk of diabetes, hypertension and cardiovascular mortality. Our laboratory has reported that oestrogens taken orally blunt GH action and cause unfavourable changes in body fat and muscle. How this happens is not known. As oral oestrogens are widely used in our society, it is important to understand the basis of their impact on GH action. SERMs, or selective oestrogen receptor modulators, are a group of drugs used in the treatment of breast cancer and osteoporosis. These substances mimic oestrogen action in some tissues, and block oestrogen action in others. Whether SERMs interfere with GH action as oestrogens do have not been studied, but such knowledge would have therapeutic significance because of their widespread and long-term use. GH action is mediated by a protein, called the GH receptor, located on the surface of target tissues. We propose that oestrogens and SERMs alter the production and function of this protein to control GH action. Thereby, this project is designed to test, in cultured cells of human origin, how oestrogens and SERMs modulate abundance of the GH receptor and its ability to mediate GH action. This work is anticipated to gain novel insights into the interaction of GH with oestrogens and SERMs. This information may also be useful for the design of new drugs devoid of adverse effects on GH action, and hence would have potentially significant implications in women s health and disease.Read moreRead less
