Summary
Biosensors use biomolecules to detect a chemical event. They are becoming important for the rapid and reliable measurement of the concentrations of molecules in fluids. In human medicine they will be of great use to general practitioners and patients for instantaneous read outs of concentrations of many different biological molecules. How well a biosensor responds depends on the method in which the biomolecule is immobilised to a surface and the signal detected.

They are becoming important for the rapid and reliable measurement of the concentrations of molecules in fluids. In human medicine they will be of great use to general practitioners and patients for instantaneous read outs of concentrations of many different biological molecules. How well a biosensor responds depends on the method in which the biomolecule is immobilised to a surface and the signal detected. We have made a significant advance in biosensing capabilities using a recombinant protein (thioredoxin) and demonstrated the improvement that is possible by (i) immobilising the protein in a highly oriented way and (ii) using a sensitive electrical signal to monitor the response. Here we will undertake more comprehensive testing by extending the number of proteins to include the 4 major classes of redox-sensitive biomolecules (proteins) in the body. This will enable us to establish the broad application of our methods and substantially improve our ability to commercialize our discoveries.Read moreRead less
Evaluation Of The Therapeutic Potential Of SFTI-FCQR, A Novel Kallikrein 4-specific Protease Inhibitor

Summary
Prostate and ovarian cancers are on the rise in Australia's ageing population. In previous work, we have studied prostate and ovarian cancer cells that we have engineered to make the protease KLK4. These cells show signs associated with aggressive tumours and in particular may have some of the changes found in cancer cells that spread from their site of origin (metastasize). In this project, we will look at a drug-like molecule that we have designed with the aim of blocking the activity of KLK4.

Summary
Congestive heart failure is fatal disease and a major disease burden for the community affecting nearly half a million Australians. Current therapies are inadequate. We seek to develop a new peptide therapy based on snake venom version of the human B type natriuretic peptide which has to be given by injection. We will produce an orally active, stable and effective treatment using a program of discovery involving testing in animals and cells.
Use Of Snake Venom Prothrombin Activators In Blood Collection Tubes To Produce High Quality Serum To Improve Patient Outcomes

Summary
The timely availability of high quality serum and plasma samples are of the utmost importance for accurate biochemical analysis in a clinical setting. This requirement is particularly true for patients on anti-clotting therapeutic agents such as warfarin and heparin. In this study we will employ potent prothrombin activators purified from snake venom to enhance the clotting efficiency of blood for serum preparation for biochemical analysis.

Summary
Vaccines are urgently needed for the prevention of HIV/AIDS. The design of this vaccine candidate is based on the display of HIV-1 envelope spikes using a related primate retrovirus envelope with a more stable assembly to anchor the the spikes in a particle.

Summary
We have identified biological evidence for a novel anti-HIV factor in a patient who has not progressed to HIV disease in 22 years. We have identified active forms in a solution, which confer potent activity against HIV. This factor helps in creating the pool of specialized antigen presenting cells, which are vital to combating with HIV in vivo. We propose to characterize this factor biologically, proteomically and genomically.
Chronic infections and cancers are major causes of global disease burden. Harnessing the immune system to combat these diseases has proven difficult and cumbersome to date. We invented a new technology to boost the ability of the immune system to fight chronic infections such as AIDS and Hepatitis C. This involves using someone�s own blood treated with sets of short proteins. We term this therapy Overlapping Peptide Pulsed Autologous CelLs (OPAL). This shows great promise in robust animal models ....Chronic infections and cancers are major causes of global disease burden.

Currently available dietary software in the Australian context only allows analysis of nutrient information. Thus when a dietitian sees a patient they must manually translate food intake to nutrient information, a largely time consuming exercise. DietAdvice is a website that was developed for people to enter in their own food intakes. The food information is sent to a dietitian who develops individualised dietary advice for them. A pilot study of the website has already found it to be feasible in the primary healthcare setting. Tested for 12 months the website was used by 224 patients from GP practices in the Illawarra region of NSW. Approximately 73% of patients were overweight and patients with a high BMI were 1.88 times more likely to use the website in the comfort of their home. Further research about the website however was needed. The research to follow on from the pilot study will aim to refine the DietAdvice website, leading towards its commercialisation for dietitians in clinical practice. The research will be broken into 3 phases. Phase 1 will involve a usability test of the website, assessing the underlying algorithms and testing it with dietitians in private practice. Phase 2 will see volunteers using the website on multiple occasions after being given pre-weighed amounts of food to eat. This will determine how reliable and accurate the information is; and phase 3 will evaluate whether the website is cost effective and if it increases accessibility of health services especially in rural areas. By confirming these attributes there will be a sound basis to commercialise the product.Read moreRead less
Application Of Follistatin To The Resolution Of Liver Fibrosis

Summary
Liver fibrosis or scarring is a consequence of a number of diseases, leading eventually to extensive damage known as cirrhosis. It is a significant health problem both here in Australia and overseas with around 180,000 patients diagnosed each year in the Western world.

It is a significant health problem both here in Australia and overseas with around 180,000 patients diagnosed each year in the Western world. Cirrhosis arises from many causes, two major groups being patients who contract hepatitis and alcoholics. People with cirrhosis have a much increased risk of liver failure, which requires liver transplantation, or of developing liver cancer, for which current treatments have limited success. We have been studying two proteins, activin and follistatin, both of which are made in the liver. We are interested in activin because it is one of the body's mechanisms to control cell growth, and also seems to stimulate the development of scar tissue. Follistatin is the natural inhibitory substance for activin. It blocks the effects of activin and helps promote cell growth in the liver. We believe that follistatin may also be useful in controlling liver scarring. This process will be studied in animal models of cirrhosis, in the hope that follistatin treatment will reduce the level of liver damage. If successful, this would be important information that would enable us to design treatments applicable to human sufferers of these liver diseases. In another part of the project, we will assess whether activin and follistatin might be useful markers of liver disease. Most patients require a liver biopsy to assess the amount of liver damage, and a simple blood test would be a far easier, less traumatic and cheaper alternative.Read moreRead less
