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 Physiological And Pathological Role Of The Bile Acid Receptor TGR5 And Its Potential Targeting For The Treatment Of Intestinal Motility Disorders And Visceral Pain.
Funder
National Health and Medical Research Council
Funding Amount
$311,860.00
Summary
Defects in the secretion of bile into the intestine cause digestive diseases, and abnormal circulating levels of bile acids induce profound itch and abnormal pain sensation. This project examines whether a cell-surface receptor (TGR5) produced by intestinal and sensory neurons mediates actions of bile acids on intestinal functions and pain. The project aims to define mechanisms of digestive and sensory disorders and identify new therapies for constipation, diarrhoea, and pain.
Endoscopic Diagnosis And Therapy: The Frontier Of Minimally Invasive Patient Care.
Funder
National Health and Medical Research Council
Funding Amount
$344,644.00
Summary
Minimally invasive diagnosis and treatment is a rapidly developing field, and has potential to significantly improve patient management and health care utilization. This research will apply endoscopic innovations to diagnose and treat early oesophageal and pancreatic cancer, with the aim to improve survival and quality of life. The research will also develop capacity to treat oesophageal motility disorders with minimally invasive endoscopic resection techniques.
Many infants and children suffer from bowel motility disorders, for example, chronic constipation affects up to 1 in 10 children. However, the cause of many of these paediatric motility disorders remains unknown. In this project, we will examine the development of wiring of the nervous system that controls bowel motility. This is the first study to investigate the development of cell-cell communication during early stages of nervous system development.
Bioresponsive Porous Silicon For Site Specific Oral Delivery Of Antibodies For The Treatment Of Inflammatory Bowel Disease
Funder
National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
This proposal aims to develop an oral antibody delivery system for treatment of inflammatory bowel disease (IBD) that affects 75000 Australians. The system will be based on porous silicon nanoparticles acting as a container to protect the antibodies, and bioresponsive coatings acting as gates to enable site specific protein delivery at the inflamed site of GI tract. The project not only holds promise for protein delivery for the treatment of IBD but other diseases like diabetes.
Inhibition Of Cellcell Actin-based Motility During Poxvirus Infection By The Kinase Inhibitor Glivec
Funder
National Health and Medical Research Council
Funding Amount
$92,950.00
Summary
Although smallpox, one of the deadliest human pathogens, was eradicated in 1980, the current global climate has resulted in fears that smallpox may be used as a biological weapon. Unfortunately the smallpox vaccine poses a serious health hazard to certain people. We have shown that Glivec, a drug used to treat cancer, has potent anti-viral affects on poxvirus replication. This project will test the effectiveness of Glivec in treating smallpox in an animal model and study how it acts.
Emu Oil And Protection From Experimentally-induced Ulcerative Colitis And Crohn's Disease
Funder
National Health and Medical Research Council
Funding Amount
$316,449.00
Summary
The inflammatory bowel diseases (IBD), encompassing ulcerative colitis and Crohn’s disease, are chronic intestinal inflammatory disorders of unknown cause. Current treatments for IBD are variably effective highlighting the need for improved therapeutic approaches. Emu Oil is reported to exert potent anti-inflammatory and antioxidant effects. Using well established experimental models, we seek to determine the potential efficacy and underlying mechanism of Emu Oil action in acute and chronic IBD.
Balance disorders are very common, but particularly in those conditions that involve the brain 'balance centres' are often difficult for doctors to diagnose. When diseases are difficult to diagnose, then recommending helpful treatment is particularly challenging. We will use a group of specialized tests to better understand these balance conditions in order to help patients receive accurate diagnoses and therefore, better treatment.
