This work aims to develop and to establish the accuracy of laboratory tests for Severe Acute Respiratory Syndrome (SARS) suitable for use and for production in Australia. Accurate and timely laboratory testing will be important in detecting imported SARS cases, and preventing establishment of the disease in Australia.

Accurate and timely laboratory testing will be important in detecting imported SARS cases, and preventing establishment of the disease in Australia. SARS is a severe, readily transmissible chest infection that first appeared in Southern China in November 2002. It has subsequently spread to 29 countries causing a total of 7747 cases and 552 deaths by mid May 2003. The greatest impact has been in China, with Canada the most severely affected country outside Asia. Approximately 15 percent of cases are fatal overall, with death rates increasing with age up to 50 percent over 65 years. There is, as yet, no specific cure or vaccine. The cause is a previously unknown coronavirus, a close relative of human common cold viruses. It spreads readily via contact with respiratory secretions, coughing and sneezing, and possibly in faeces. The virus is able to persist in the environment for days. An international network of WHO laboratories has made rapid progress in developing laboratory tests. Although this expertise will assist Australia in developing its own laboratory capability, Australia's laboratory test needs cannot be met from overseas. SARS laboratory tests and protocols will be developed in Australia over a 3-month period by a consortium of expert Australian laboratories. These include the Victorian Infectious Disease Reference Laboratory, the Institute of Clinical Pathology and Medical Research at Westmead Hospital, CSIRO's Australian Animal Health Laboratory, the Cooperative Research Centre for Diagnostics, and the Western Australian Centre for Pathology and Medical Research. Tests will include methods for detection of the SARS virus in specimens, and detection of antibodies to SARS in the blood. Production of some key reagents by genetic engineering techniques is intended to improve their availability. Robustness of test methods in a diagnostic laboratory setting will be evaluated, and a quality assurance program will be implemented. An expert advisory group will assist in the development of test performance and interpretation protocols.Read moreRead less

Summary
This project will develop two molecular diagnostic methods to detect the SARS virus. One will be based on a commonly used polymerase chain reaction (PCR) technology for viruses and the other will be based on a newly RNA amplification method, rolling chain amplification (RCA). Using RCA will provide a sensitive, contamination-free and reliable test during early stages of SARS virus infection that is not currently available.It is important to study the viral evolution and mutations by monitoring c ....This project will develop two molecular diagnostic methods to detect the SARS virus. One will be based on a commonly used polymerase chain reaction (PCR) technology for viruses and the other will be based on a newly RNA amplification method, rolling chain amplification (RCA). Using RCA will provide a sensitive, contamination-free and reliable test during early stages of SARS virus infection that is not currently available.It is important to study the viral evolution and mutations by monitoring changes occurring in the virus. These changes are critical in defining the origin of the virus, its movements, and predicting changing patterns in pathogenesis of particular viral strains. As these analyses involve a variety of primary strains of SARS from patients, the issue of viral variability in relation to diagnosis can be addressed well through the proposed study. Together, these data may prove to be useful in future vaccine development, as has been evident from a number of flu viruses. Viral load during the course of disease will be used to predict disease prognosis and also to identify super-spreaders as they may carry large amount of virus but have less severe clinical symptoms. This project will be a milestone in molecular diagnosis, not only for the SARS virus, but also to other viral diseases such as HIV.Read moreRead less

ENGAGE will do this through the integration of very large datasets already available from a substantial number of large and well-characterised samples. The resulting ENGAGE resource will represent a research investment >€100M (>AU$160M) and provide unprecedented power to discover disease and trait susceptibility genes. QIMR will contribute 12,000 twins for ENGAGE joint analyses and provide analytical expertise in the analysis of disease and genetic data related to lifestyle and metabolic traits, with particular emphasis on cardiovascular disease, type 2 diabetes and migraine risk factors. Our laboratory will also perform vital further genetic studies to establish the causal relationship between the genetic variants concerned and the traits of interest. Most importantly, our direct participation will allow the translation of these findings into the Australian population and clinical arena.Read moreRead less

Apathy is the state of loss of motivation and emotional withdrawal that occurs in a high proportion of patients with Alzheimer’s disease. These patients require more management and support, given their reliance on others to schedule their activities and initiate behaviours even when they are still capable of performing the activities. In spite of the high frequency of apathy in dementia and the high potential of negative effects on patients and caregivers, little is known about the cause of this phenomenon, its potential influence upon the long-term progression of Alzheimer’s disease, and on its impact upon caregivers’ emotional well-being. The main aim of our proposal is to examine the mechanism, clinical relevance and impact of apathy in Alzheimer’s disease. More specifically, we will determine whether apathy predicts more severe depression, increasing motor problems, and a faster progression of cognitive and functional problems. Using state-of-the-art neuroimaging techniques we will examine the association between apathy and abnormalities in specific brain regions. Finally, we will examine whether caregivers of patients with apathy have relatively more severe emotional problems, a higher care giving burden and poor quality of life.Read moreRead less

This project brings together malaria biologists with chemists and computer scientists to explore this promising field. We will apply modern methods of drug target characterisation to find the most promising enzyme targets involved in protein synthesis and to identify inhibitors as leads for developing antimalarial therapies. Australian researchers involved in this project will provide expertise in bioinformatic prioritisation of Plasmodium drug targets from the aminoacyl tRNA synthetase family of enzymes. We will use structural modelling and docking experiments to identify promising antimalarial inhibitors, and will optimise assays to assess the effects of these inhibitors. We will also apply modern molecular biology tools to validate these enzymes as anti-malarial drug targets.Read moreRead less
