Non-HFE Haemochromatosis In Australia: Natural History And Molecular Characterisation
Funder
National Health and Medical Research Council
Funding Amount
$179,948.00
Summary
Hereditary haemochromatosis (HH) is a disorder characterised by excessive iron absorption and build up of iron in body organs such as the liver. The excess iron can be toxic and cause disease. Most HH is caused by mutations in the HFE gene. Other forms are caused by mutations in other genes. This project will characterise a new form of HH that is unrelated to any of the previously known genes. The project aims to find the gene for this new condition by genetic analysis in a large family.

Summary
This project aims to identify the genes most commonly mutated in individuals with advanced glaucoma. Identification of such genes will lead to improved understanding of glaucoma pathogenesis, a better ability to predict risk, and the identification of drug targets for novel therapies.
The genomics of adaptation in Wolbachia pipientis, an emerging biocontrol agent. Australians are increasingly exposed to insect-transmitted diseases such as dengue fever. Novel biocontrol methods using the bacterium Wolbachia aim to control insect populations to reduce disease transmission. Our research will be the first to investigate genomic variation and the process of adaptation to new insect hosts in Wolbachia. The novel data and understanding of evolutionary processes we generate will be c ....The genomics of adaptation in Wolbachia pipientis, an emerging biocontrol agent. Australians are increasingly exposed to insect-transmitted diseases such as dengue fever. Novel biocontrol methods using the bacterium Wolbachia aim to control insect populations to reduce disease transmission. Our research will be the first to investigate genomic variation and the process of adaptation to new insect hosts in Wolbachia. The novel data and understanding of evolutionary processes we generate will be critical for screening bacterial biocontrol candidates and designing biocontrol release strategies. It will also strengthen the position of Australian research as a world-leader in the fusion of post-genomics and applied microbiology. Read moreRead less
Molecular Epidemiology Of Melioidosis In Australia

Summary
Melioidosis is an important infection in northern Australia. It is a common cause of fatal pneumonia and blood infection in the region. Two outbreaks of melioidosis with fatalities occurring in remote Aboriginal communities have been linked to contamination of the community water supply with the melioidosis bacteria, Burkholderia pseudomallei. In addition, a rare form of melioidosis affecting the brain and spinal cord has resulted in a number of deaths in healthy Aboriginal people and also a num ....Melioidosis is an important infection in northern Australia. It is a common cause of fatal pneumonia and blood infection in the region. Two outbreaks of melioidosis with fatalities occurring in remote Aboriginal communities have been linked to contamination of the community water supply with the melioidosis bacteria, Burkholderia pseudomallei. In addition, a rare form of melioidosis affecting the brain and spinal cord has resulted in a number of deaths in healthy Aboriginal people and also a number left living in remote communities with severe disabilities such as complete paralysis of both legs. Melioidosis has also been identified in two outbreaks occurring over many years in separate locations in southern Australia. It is thought that it may have been introduced to these regions by imported animals, eg via cattle drives, and human fatalities have occurred after local flooding in these temperate locations. This project is built on the ongoing melioidosis collaboration between researchers in Western Australia, the Northern Territory and Queensland. The aim is to use new DNA fingerprinting methods developed specifically for the melioidosis bacteria to understand better why melioidosis can be such a severe disease and how it spreads from the environment to humans and animals and also how it has possibly spread within Australia and overseas. Better recognition and treatment of melioidosis has resulted in a halving of the death rate from this disease in northern Australia (mortality decreased from 40%-18%). This study aims to give us a better understanding of how this soil and water bacteria interacts with humans to cause such severe disease and will hopefully result in new primary preventative measures to complement the improved diagnosis and treatment.Read moreRead less
Strain-level Characterisation And Visualisation Of The Mucosal Microbial Communities Associated With Inflammatory Bowel Disease (IBD) For The Development Of Novel Biotherapeutics
Funder

Funding Amount
$1,181,878.00
Summary
Australia has one of the highest incidence rates in the world of Inflammatory Bowel Disease (IBD), a debilitating inflammatory condition of the gastrointestinal tract. Cutting-edge molecular and visualisation technologies will be used to examine the role of the gut microbiome in IBD, and identify specific members of this community to be used as new therapies to suppress inflammation and improve outcomes for patients with IBD.
Next generation dengue diagnostics. The 2009 dengue epidemic was widespread and the largest in North Queensland for 50 years. The outbreak was not quickly contained despite an extensive education program and a mosquito control taskforce. All four types of Dengue were detected, greatly increasing the chance of more severe complications such as Dengue haemorrhagic fever and Dengue shock syndrome. This project will improve our knowledge of Dengue proteins used in tests to diagnose the virus. The ne ....Next generation dengue diagnostics.

All four types of Dengue were detected, greatly increasing the chance of more severe complications such as Dengue haemorrhagic fever and Dengue shock syndrome. This project will improve our knowledge of Dengue proteins used in tests to diagnose the virus. The new knowledge will be used to develop an easy to use test to diagnose Dengue infection early, rapidly and accurately. Effective diagnosis of Dengue will then allow timely implementation of intervention strategies (mosquito control, public advice, isolation and care).Read moreRead less
EXAMINING THE RELATIONSHIP BETWEEN MATRIPTASE-2 AND HEMOJUVELIN, TWO ESSENTIAL REGULATORS OF IRON HOMEOSTASIS
Funder
National Health and Medical Research Council
Funding Amount
$533,541.00
Summary
The control of iron levels is important in health and well being. Too little can lead to iron deficiency and anaemia, conversly too much can lead to haemochromatosis and tissue damage. We will examine the role of two proteins, matriptase-2 and hemojuvelin that when mutated cause iron deficiency or iron overload respectively. We will study how these proteins interact and work in opposite directions to control iron levels. The results will help to develop new therapeutics for iron disorders.
The Burden And Risk Factors Of Depressive Disorders In Indigenous Australians: Implications For Early Detection And Prevention
Funder

Funding Amount
$318,768.00
Summary
This Fellowship addresses the high rates of depression amongst Indigenous Australians. The proposed work will quantify the extent to which two major risk factors contribute to the burden of depression in this population and the burden avertable from interventions to modify these risk factors. Findings would inform resource allocation and health service delivery, and in doing so, present opportunities for improvements in the health of Indigenous Australians.
A Practice Change For Patients With Severe Chronic, Clinically Unexplained Gastrointestinal Symptoms: A Randomised, Controlled Intervention To Assess Efficacy And Cost-effectiveness
Funder

Funding Amount
$1,276,080.00
Summary
Unexplained chronic gastrointestinal symptoms are extremely common and costly to the health system. Currently patients are managed in the hospital setting with the 'typical' face-to-face office-based model which sees the clinician spending valuable time gathering information and often treatments (e.g. allied health) delivered in a non-standard way. This project will evaluate the effectiveness of a new standard best-practice clinical model with a structured technology enabled management approach.
