Summary
The proposed research program, using a combinantion of structural biology and biophysical techniques will provide insight into the role of novel AB5 toxin from E. coli. This study will not only improve our fundamental understanding the mode of action of this toxin from this devastating pathogen, but could lead to the design of rational antimicrobials. The knowledge gained will increase Australian international research profile.

Summary
Heroin addiction is a major national and international problem costing hundreds of millons of dollars to Australia alone. The major form of treatment is methadone taken as maintenance treatment once a day. While methadone is effective in most addicts, about one third of them complain that it does not last long enough and they either tolerate this inadequate form of treatment or are prescribed a newer drug as part of a clinical trial or drop out and revert to heroin. We have previously shown that ....Heroin addiction is a major national and international problem costing hundreds of millons of dollars to Australia alone. The major form of treatment is methadone taken as maintenance treatment once a day. While methadone is effective in most addicts, about one third of them complain that it does not last long enough and they either tolerate this inadequate form of treatment or are prescribed a newer drug as part of a clinical trial or drop out and revert to heroin. We have previously shown that the blood levels of methadone are important in determining its best use and specifically, that those addicts for whom methadone does not hold have a greater drop in their blood levels after methadone has been absorbed into the body. This drop in blood levels is mainly due to methadone's redistribution throughout the body. Very little is known about how methadone distributes and redistributes throughout the body but it appears that the lung is the most important organ. A number of questions need to be answered to improve methadone's use: 1. How quickly is methadone taken up into the lung compared to the brain; 2. Why is the lung able to take up and release a large amount of methadone; 3. How does decreased respiration influence the lung and brain uptake of methadone; 4. What happens when another drug is prescribed (such as an antidepressant) which reduces the lung uptake of methadone; 5. Do some of the newer drugs for heroin addiction have better lung distribution and binding properties. We will perform studies of the concentrations of methadone and newer drugs in sheep that will provide the scientific basis for answering these questions and permit better use of drug treatment for heroin addiction.Read moreRead less
The study builds on strong existing NHMRC funded collaborative links between Sri Lanka and Australia in research which has reduced mortality and provided better evidence for treatment of poisoning. Current measurements of kidney damage are slow to change and insensitive. We will study new ways to measure acute kidney toxicity in people with poisoning and snakebite. We aim to determine whether these new measures are better predictors of the short and long term effects on the kidney.
Artificial Synthesis Of The Type III Secretion System Translocon. A New Approach To Vaccine Design

Summary
Today hospitals are plagued with bacterial infections that do not respond to antibiotics. The problem exists because although antibiotics are effective at killing bacteria, this paradoxically also helps the drug-resistant bacteria thrive. We will pioneer a completely new approach to vaccine design that allows us to construct a vaccine that protects us from bacterial infection without killing the bacteria. The vaccine should therefore be far less susceptible to drug resistance.
High performance electrolyte for the vanadium redox flow battery. Vanadium batteries present a highly-scalable, sustainable solution for storage of renewable electricity, but the technology needs to be improved for robust and efficient operation in the warm Australian climate. This project aims to design and extensively test new high-performance electrolyte compositions with advanced thermal stabilising additives for safe long-term battery operation at 60 °C.

Vanadium batteries present a highly-scalable, sustainable solution for storage of renewable electricity, but the technology needs to be improved for robust and efficient operation in the warm Australian climate. This project aims to design and extensively test new high-performance electrolyte compositions with advanced thermal stabilising additives for safe long-term battery operation at 60 °C. New knowledge in materials science and electrochemistry will be generated. The core outcome of the project is a sustainable large-scale energy storage technology ready for immediate application in Australia. This will support the transition of the Australian energy sector to renewables and provide businesses with distributed energy storage solutions.Read moreRead less

Summary
There is a well-documented need to replenish the antibiotic pipeline with new products to combat the rise of drug resistant bacteria. In this project, the enzyme dihydrodipicolinate synthase (DHDPS) is targetted which is essential to bacterial viability. A number of independent but synergistic drug discovery approaches are investigated to develop and test DHDPS inhibitors in the pursuit of a novel class of antibiotics.

Summary
Current therapies for prostate cancer lose their efficacy as the cancer advances. Moreover, despite the spread of cancer being the major cause of prostate cancer mortality, there is no therapy available which selectively targets this process, thus new agents are needed. By using computer modelling to predict molecules that bind to the cell surface protein CD151 and testing these in biological assays, we aim to discover molecules that reduce cell migration of prostate cancer and that can be devel ....Current therapies for prostate cancer lose their efficacy as the cancer advances.
