Targeting Neurovascular Communication As A Novel Way Of Reducing Vision Loss In Diabetes

Funding Amount
$986,663.00
Summary
Diabetes is a leading cause of blindness. Here, we evaluate whether diabetes causes changes in the way neurons signal to blood vessels, and whether blocking some of the signals from neurons reduces blood vessel abormalities. Overall, this information is critical to our understanding of the early changes that occur during diabetes and whether novel treatments used early in diabetes can prevent long term changes and vision loss.
Hysterectomy, Oophorectomy And Long-term Chronic Disease - The HOLD Study
Funder
National Health and Medical Research Council
Funding Amount
$690,006.00
Summary
Hysterectomy, with or without the removal of ovaries, undertaken for non-cancerous problems may have long-term consequences for other health conditions like cardiovascular disease and cancer, but existing evidence is inconsistent. This large population-based study will use linked health data from the states and the Commonwealth to investigate these associations. The information from our study will help women and their doctors to make the better-informed decisions about their treatment.
Dissecting Brain Network Ageing Using Whole Brain Imaging

National Health and Medical Research Council
Funding Amount
$692,964.00
Summary
In this proposal, we will make the first attempt to map the whole brain activity change during ageing using a series of state-of-the-art techniques. We will also identify genetic and pharmacological interventions that improve brain network function during ageing. Outcomes from this research will provide an unprecedented understanding of functional ageing within the brain and identify therapeutic interventions to prevent this process.
Organisation Of The Genome During The Development Of Antibody-secreting Cells

Funding Amount
$886,155.00
Summary
Each cell of our body contains over two metres of DNA that must be correctly packaged in order for our cells to function. We are using cutting-edge molecular biology techniques to study how this DNA circuitry is established in the white blood cells of our immune system that produce antibodies. Our novel approaches will reveal unique strategies to modulate immune responses to our benefit.
Epigenetic Biomarker Discovery For Cardiovascular Disease Risk Stratification Of Women Following Preeclampsia
Funder
National Health and Medical Research Council
Funding Amount
$1,275,101.00
Summary
Those women whom have suffered from severe complications during pregnancy have an increased risk of developing heart disease. This increased risk may be due to epigenetic changes during pregnancy that alter the expression of specific genes. These epigenetic changes persist after birth and increase heart disease risk for these women. This project seeks to evaluate those epigenetic changes associated with severe pregnancy complications predicting heart disease in a large group of Australian women.
A Suture-less Cannula For Rapid, Off-bypass Implantation Of Left Ventricular Assist Devices
Funder
National Health and Medical Research Council
Funding Amount
$816,491.00
Summary
Heart transplantation is the ideal treatment for 300,000 Australians living with chronic heart failure. The lack of donor hearts necessitates the use of implantable mechanical hearts; however, bleeding and blood clots are common due to outdated surgical tools, poor body-device integration and unnatural device blood flow. This project will address these limitations through the development of a rapid and safe implantation tool that integrates with the body and produces natural blood flow dynamics.
A Novel Interaction Between The Immune And Vascular Systems In Early-onset Preeclampsia; An Opportunity For New Treatments?
Funder
National Health and Medical Research Council
Funding Amount
$921,623.00
Summary
Preeclampsia is a pregnancy complication that leads to poor birth outcomes and elevated lifelong cardiovascular disease risk in 4 million women each year. It has no cure and treatments are limited because the causal mechanisms are not understood. We have identified a specialised immune cell in the mother's blood that assists blood vessels to function properly in pregnancy. We will assess whether interventions to enhance these cells can improve poor blood vessel function and pregnancy outcomes.
About one in eight known genetic disorders involve DNA alteration that activates a cellular quality control mechanism that disables the affected gene. This mechanism is more efficient in some individuals than others. It can influence disease outcomes and severity. We will engineer and apply tools and models to measure and manipulate this crucial cellular mechanism. This will allow us to predict disease severity as well as to intervene where a manipulation of this mechanism will be beneficial.
An Integrative Approach To Define And Attenuate Genomic Risk Of Coronary Artery Disease
Funder
National Health and Medical Research Council
Funding Amount
$988,454.00
Summary
One in four individuals that have a heart attack do not have traditional risk factors such as high blood cholesterol levels. This highlights the importance of 'family history', which we can now quantify as 'genetic risk'. These studies will determine (i) which genes are important in contributing to this genetic risk (ii) how these genes change biological pathways to increase risk and (iii) the effectiveness of modulating these biological pathways to reduce the risk of heart disease.
Novel Modelling To Improve Decision-making For Neighbourhood Design To Reduce Chronic Disease Risk
Funder
National Health and Medical Research Council
Funding Amount
$901,564.00
Summary
Research on urban design that might support liveability and health (the 20-minute neighbourhood concept) has used analytic methods that do not account for the complexity of urban environments. This study innovatively uses a flexible and applicable approach (Bayesian Networks) to show where neighbourhood features operate uniquely or not, which features can be prioritised, which are cost effective, and how much of each feature is needed to achieve improvement in reducing risk of chronic disease.
