Summary
Liver disease is a serious health problem. Viral hepatitis, obesity and alcohol can result in end-stage liver disease. Organ transplant is the only treatment available. A widening gap between organ donations and recipients mandates alternative treatments are developed. Cell transplantation and artificial liver devices are alternatives which can use liver progenitor cells. We will investigate how factors grow and convert them into liver cells for treating liver disease patients.
When Prometheus Needs A Hand – How Human Amnion Epithelial Cells Resolve Fibrosis And Regenerate The Liver

Summary
Cirrhosis can progress to end stage disease for which transplantation provides the only hope for survival. Liver donors in Australia are scarce; the need for donor organs is increasing. Using stem cells to repair and regenerate damaged liver may provide an alternative to organ transplantation. We are studying placental stem cells that can decrease inflammation and increase progenitor cells to repair and regenerate liver. Our goal is to use these stem cells as treatment for human liver disease

However, there is a risk of injury during this participation and efforts need to be undertaken to reduce this risk so that spor is safe for all. Sports injury prevention efforts to date in Australia have been severely hampered by a lack of evidence supporting currently advocated countermeasures. This concern has been recognised by both the NHMRC and the Commonwealth Department of Health and Ageing. It is imperative that we formally evaluate the effectiveness of sports injury countermeasures in the context of broad community level participation in sport, in contrast to previous research focussed on professional sport, and begin to deliver the preventive measures to the community. Australian football is a popular sport throughout Australia and it is associated with more medically-treated injuries than any other sport. Knee injuries are particularly common and can have severe consequences. One of the most commonly recommended knee injury prevention strategies is a well-designed exercise training program. Despite their potential to significantly reduce injury rates, the effectiveness of exercise training programs to prevent knee injuries in football, and indeed in most other sports, has not previously been assessed but has been identified as a priority research area by the NHMRC. This project will determine the effectiveness of exercise training programs for preventing knee injuries in community-level football players by monitoring injury rates, player behaviours and player attitudes before and after the training programs are implemented.Read moreRead less
Towards A National Sports Safety Strategy - Addressing Facilitators And Barriers Towards Safety Guideline Uptake.

Funding Amount

Summary
Most sports injury prevention evidence is yet to be translated from professional to community sports settings. Using community-based Australian football clubs, this project will develop and evaluate the strategic implementation of an evidence-based sports safety package. This will provide important information about how to best support community sports clubs to ensure evidence-based safety programs are translated into sustainable policies and practice and public health benefits are maximised
Development Of Microscope-in-a-needle Devices For Improved Clinical Diagnostics

Summary
We have developed a new high-resolution optical imaging technology. The unique aspect of our research has been to redesign the imaging probe, miniaturising it to a few hundred microns in diameter, and encase it in a hypodermic needle – a ‘microscope-in-a-needle’. We are developing specific imaging probes to aid in the assessment of lung disease; the diagnosis of liver disease; and integrated into a brain biopsy needle to enable safer brain biopsies.
Reprogramming Macrophage Function In The Elderly To Rescue Impaired Inflammatory Responses To Muscle Injury

Funding Amount
$410,983.00
Summary
Muscle injury in the elderly often takes longer to heal than in younger people, however the cells responsible for this delayed healing are not well understood. Key inflammatory cells required for muscle repair in young hosts are macrophages. However, during aging we have shown that macrophage function is altered, but the mechanism is unknown. This project aims to determine the mechanisms behind age-related changes to macrophages and whether they can be targeted to improve elderly muscle repair.
The Effect Of Human ApoE Isoforms And ApoE Receptors On The Clearance Of Oligomeric A 42 By Hepatocytes In Vitro

Summary
Alzheimer's disease (AD) is a progressive memory disorder. Increased production of a short peptide called amyloid- (A ) aggregates to form the sticky masses in the brains of AD patients. The amount of A in the brain is a balance between production and clearance. Surprisingly, we recently demonstrated that the liver clears the majority of A . These results connect AD and cardiovascular disease (CVD), enabling current CVD therapeutics to target A clearance by the liver.
The Importance Of Neutrophil Plasticity In Early Cystic Fibrosis Lung Disease

Summary
Lung disease is a lifelong problem for people with cystic fibrosis (CF). Blood immune cells called neutrophils swarm the lung and cause ongoing damage. No treatments exist because how CF lungs talk to neutrophils is poorly understood. I will apply new skills from an international neutrophil expert to study samples from AREST CF, a world leading CF research group. This unique combination will recreate the early CF lung in the laboratory, testing triggers of CF lung disease and potential drugs.
Epithelial Drivers Of Neutrophil Plasticity In Early Cystic Fibrosis Lung Disease

Summary
Why airway inflammation becomes chronic so early in life for people with cystic fibrosis (CF) is unclear. This project will use the latest techniques to characterise immune cells found in airways of infants with CF and model in the laboratory how immune cells react to the CF airway. We will challenge CF airway cells with different bugs that can infect the lung, then see if the responses by CF airway cells can change the normal response of immune cells, triggering chronic disease.
Restoration Of Diabetes Associated Cognitive Deficits Through The Modulation Of Cerebrovascular Integrity

Summary
Diabetes is known to increase the risk of dementia. Although the mechanisms are currently unknown, a recently emerging body of evidence suggest that damaged blood vessels of the brain may be central to onset and progress of cognitive dysfunction. Consistently, the dysfunction of brain blood vessels is often observed in the brain of diabetes subjects. Therefore, this project will investigate whether the amelioration of disrupted brain blood vessels restores the cognitive function in diabetes.
