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.

Role Of Microparticles In Cardiac Ischemia Reperfusion Injury
Funder

Funding Amount
$55,575.00
Summary
Interventional cardiology has reduced the mortality rate associated with heart attack, unfortunately the prevalence of heart failure has subsequently increased, caused in part by reperfusion injury of previously occluded vessels. We aim to identify novel insights into the pathogenesis of IR injury in the heart, as well as the development of new approaches to prevent cardiac damage during cardiac surgery, transplantation, post-angioplasty and coronary artery stenting.
Retinal Vascular Structure And Function As Markers Of Endothelial Dysfunction.
Funder

Funding Amount
$104,664.00
Summary
Coronary heart disease (CHD) due to atherosclerosis (thickening of blood vessels) remains the leading cause of death in Australia, but visualisation of heart arteries usually requires invasive testing. Blood vessels in the eye (retina), can be viewed easily and may be indicative of blood vessel function in the heart and rest of the body. This study aims to explore the relationship between eye and heart blood vessels. Retinal imaging may thus enable earlier detection of patients at risk of CHD.
Hypertension Induced Inflammation In The Endothelium: The Signalling Pathways Involved
Funder
National Health and Medical Research Council
Funding Amount
$58,313.00
Summary
Patients with high blood pressure are at an increased risk of heart attack and stroke in western societies. It appears that increased pressure induces an inflammation response which leads to the development of atherosclerosis. The aim of this project is to understand the vascular inflammatory mechanisms induced by high blood pressure with the view to prevent blood pressure-related complications such as atherosclerosis.
Investigating The Mechanisms Underpinning The Dynamic Vessel Response In People With Diabetic Retinopathy

Funding Amount

Summary
Endothelial dysfunction has been well-hypothesised as one of the key players in the pathogenesis of DR. However, there is strong evidence suggesting a neurovascular coupling mechanism in the retinal circulation during flicker. It is therefore unclear whether reduced flicker light induced vasodilation observed in diabetes and DR is associated with endothelial dysfunction, an impairment of neurovascular coupling or both. This project aims to address this important knowledge gap.
