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.

An abnormal blood pressure (BP) response to a clinical exercise stress test is a signal for increased cardiovascular disease risk. However, current clinical guidelines do not provide evidence based information surrounding values that may constitute this increased risk. The EXERcise stress Test collaboratION (EXERTION) aims to fill this knowledge gap via establishment of a large, national database of exercise stress test results, linked to acute and chronic cardiovascular disease outcomes.
The Role Of Microbiome Activity In Diet-disease Relationships: Anthocyanins, Flavanols And Hypertension
Funder

Funding Amount
$366,252.00
Summary
By clarifying the role that intestinal bacteria play in the blood pressure lowering effect of anthocyanins and flavanols, this project will unravel potential ways that we can use bacteria to improve the effectiveness of dietary interventions for the prevention of high blood pressure, and ultimately, cardiovascular disease and stroke.
Chronotherapy Of Hypertension In Obstructive Sleep Apnoea
Funder
National Health and Medical Research Council
Funding Amount
$232,738.00
Summary
Obstructive Sleep Apnoea (OSA) is linked with excess cardiovascular disease, and this is partly attributed to increased high blood pressure (hypertension). Understanding how both conditions exacerbate hypertension and whether blood pressure control can be improved by altering the time that medication is taken will lead to improvements in health.
Central Excitatory Pathways Of The Autonomic Nervous System

Funding Amount
$323,164.00
Summary
The central pathways of autonomic regulation are well known, but the functions of specific pathways in physiological settings remains an elusive goal. We will evaluate the role of two physiologically important autonomic pathways for sleep apnea and the circadian control of the body by genetically deleting the transmitter, glutamate, in transgenic mice. A greater understanding of these pathways is critical in unraveling autonomic nervous system function in health and disease.
Role Of The Medial Amygdala In Developing Neurogenic Hypertension

Funding Amount
$302,123.00
Summary
We aim to investigate the underlying mechanisms and pathways that regulate the activity of neurons located in the medial amgydala during stress that contribute long term to the development of hypertension. This study is highly relevant to people who inappropriately respond to typical daily stressors and we aim to provide direction for developing specific therapies to interrupt the adverse cardiovascular consequences of chronic stress.
Acute Traumatic Coagulopathy- Mechanisms And Measurement
Funder
National Health and Medical Research Council
Funding Amount
$188,226.00
Summary
Acute traumatic coagulopathy (ATC) refers to impaired blood clotting post major trauma and is associated with high, early mortality. Inability to predict this disorder and poor knowledge regarding its detailed biochemical mechanism has hindered development of evidence based guidelines to manage patients with ATC. This project aims to correlate early biochemical disorders with clinical management and outcomes post trauma to determine mechanisms leading to ATC and determine management strategies.
