The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

The Aboriginal Cardiovascular Omega-3 Randomised Controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$1,090,119.00
Summary
CVD is the primary contributor to life expectancy differentials between Indigenous and non-Indigenous Australians. Even when cardioprotective therapies are optimally used, residual risk of adverse events is often observed. Testing of additional therapies that improve survival among Indigenous people with CVD is required. Omega 3 fatty acids can improve multiple atherogenic pathways. This trial will assess the impact of Omega 3 in Aboriginal patients with CVD.
How Does Dietary Cholesterol Induce Non-alcoholic Steatohepatitis?
Funder
National Health and Medical Research Council
Funding Amount
$802,600.00
Summary
Non-alcoholic fatty liver disease is the most common liver disease that can progress to non-alcoholic steatohepatitis (NASH), cirrhosis and liver cancer. Dietary cholesterol is a major risk factor for NASH. We can demonstrate that cholesterol changes the gut bacteria. These bacteria generate toxic chemicals (bile acids) that signal to the liver and induce NASH. In this project, we use novel ways to clarify the mechanisms of liver inflammation and test novel therapeutic approaches to reverse it.
Determinants Of Inequality In Child Oral Health At School Age–A Prospective Cohort Study
Funder

Funding Amount
$1,229,853.00
Summary
This study aims to examine effects of socioeconomic circumstances as determinants of child oral health conditions, which can be mediated by dietary patterns, use of fluoride and dental service.
A Novel Metabolic Role For UDP Glycosyltransferase 8 (UGT8)
Funder

Funding Amount
$419,144.00
Summary
The UDP glycosyltransferases (UGTs) are a family of enzymes that remove drugs and toxins from the human body as well as control levels of naturally produced molecules such as bile acids and hormones. We found that a new member of this family called UGT8 processes bile acids in the kidney and intestine and can affect how bile acids act to regulate metabolism. Our studies uncover new roles for bile acids in liver, kidney and gut health and in metabolic disorders such as diabetes and obesity.
Many heart diseases are associated with impairment of energetics of the heart. Improving the heart's energetics can lead to improved survival and long-term outcomes. Perhexiline is a heart medication that works by improving the way the heart uses energy. Although effective, it is associated with long-term toxicities. Better understanding of this medication may lead to less adverse effects and also provide a basis for further investigation of drug development in the future.
Good nutrition is a vital element in a healthy start to life. Determining the correct foods to ensure that pregnant women meet both their needs as well as those of their new baby can be very confusing. Do I need to take iron supplements? How can I ensure I get enough iodine? This project will develop new methods for evaluating the effects of nutrients and to pass that information on to health practitioners so that Australian mothers will be in no doubt about the best diet for them and their chil ....Good nutrition is a vital element in a healthy start to life.

Dissecting The Role Of The IL-3 Receptor Alpha Subunit And Beta-catenin In Acute Myeloid Leukaemia
Funder
National Health and Medical Research Council
Funding Amount
$583,312.00
Summary
Leukaemia is a devastating form of blood cancer affecting both young and old. We aim to understand the mechanisms of uncontrolled cell growth associated with acute myeloid leukaemia. We focus on the role of key growth regulators that are abnormally active in the critical leukaemia stem cells. Understanding the biological and molecular properties of these cells is of considerable importance for development of the next generation of leukaemia therapies.
Effects Of The Fatty Acid, Lauric Acid, On Energy Intake And Gut Motor And Hormonal Function In Health And Obesity
Funder
National Health and Medical Research Council
Funding Amount
$744,645.00
Summary
Obesity is largely due to energy intake exceeding energy expenditure, thus, strategies that reduce energy intake will result in weight loss. We discovered recently that the fatty acid, lauric acid, markedly reduces energy intake. Our studies will determine the effects of lauric acid on energy intake and body weight reduction in obese subjects. The research is a new initiative and explores the potential of lauric acid as a novel, nutrient-based and side-effect free approach to obesity management.
New insulins for the improved management of diabetes. The prevalence of diabetes has increased dramatically over the past few decades and now this condition is widely considered the world’s fastest growing disease. New insulins with improved pharmacological and storage properties are desperately needed, and this project will work on chemical synthesis enabling designer insulins to be prepared for improved management of diabetes.
Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors w ....Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors will be used to devise a simple portable colorimetric test that can be performed in the vineyard or the winery. The ability to rapidly determine the level of grape contamination with phenolic glucosides would give Australian wine growers and wine makers a powerful tool to mitigate the effects of bushfires.Read moreRead less
