Stroke is a major cause of death and disability in adult across the world. Understanding how exactly brain cells are affected in stroke and how they are injured, and how they response to treatment is important in order to develop new treatment to maximize recovery and minimize brain injury after stroke. This project uses advanced MRI being performed at several time points after a stroke to study how the brain tissues recovers or dies after a stroke.
Urine Proteomics As A New Diagnostic Approach For Cardiovascular Risk And As A Discovery Tool For Novel Pathomechanisms In Atherosclerotic Disease

Summary
Atherosclerosis (hardening of blood vessels) followed by blockage is the leading cause of death due to heart attacks and strokes. Up until now there has been no simple tests to predict this reliably.The outcome of this project will give us a better understanding of atherosclerosis and provide a simple non-invasive urine test to detect atherosclerosis which would lend clinicians the opportunity to intervene early.
Establishing A Model Of Occlusive Middle Cerebral Artery Stroke In The Sheep

Summary
Stroke is the second leading cause of death and the highest cause of disability in adult Australians, however our lack of an animal model that correctly replicates the human condition has severely hindered our understanding and treatment of the disease. This research project aims to develop a model of stroke in the sheep using a surgical approach that future researchers may use and adapt to further explore the physiology of the disease and trial therapeutic techniques to treat stroke.
The majority of stroke results from focal brain infarction, followed by substantial secondary excitotoxic damage in the surrounding areas. Tau has been shown to contribute to excitotoxicity and neurodegeneration in mouse models of Alzheimer’s disease (AD). Preliminary data show that tau reduction also protects against excitotoxic damage after experimental stroke. We aim to dissect the molecular mechanisms of stroke using a tau-deficient mouse model.

Summary
Stroke populations are at a risk of dementia. Structural changes have been demonstrated to precede cognitive changes, providing a potential for early diagnosis and intervention. Magnetic resonance imaging markers of structural connectivity are powerful predictors of dementia. As a longitudinal study, this proposal has the unique advantage that I will be able to detect changes in post-stroke brain networks in the 3 years after stroke. This raises the potential for future clinical application.
Smartphone Based Secondary Prevention Program For Patients With Acute Coronary Syndromes: A Randomised Control Trial

Summary
Patients at the highest risk of premature death, heart attacks and re-hospitalization are those with known coronary heart disease. Secondary prevention strategies and cardiac rehabilitation are under-utilised in clinical practice. We aim to close this treatment gap by establishing the role of a smartphone based secondary prevention program in patients who have experienced a heart attack. Our innovative model of care may empower patients to optimise their cardiac health.
Myelodysplastic syndromes (MDS) are disorders of blood-forming stem cells characterised by low blood counts and progression to acute leukaemia. Epigenetics refers to changes in gene expression without changing the underlying DNA sequence. More than half of MDS have mutation/s in epigenetic regulators, providing evidence that epigenetics is an important contributor to the disease. The goal of this project is to better understand how epigenetics contribute to MDS and discovery of new therapies.
An Investigation Into ACE2 As A Molecular And Genetic Link To Human Coronary Artery Disease

Summary
Coronary artery disease (CAD) is a leading cause of death but remains underdiagnosed so better tests are needed. We plan to perform a simple, new blood test in those with and without CAD. Our theory is that blood levels will be significantly increased only in those with CAD. If our theory is confirmed, this test may then be used to better predict those with CAD even before they develop symptoms. It will allow provision of early prevention strategies which will likely reduce complications of CAD.
This project will investigate the link between vitamin D and falls in people with stroke. It will be the first study to examine associations between vitamin D and falls in people with stroke and establish whether interventions to prevent falls in people with stroke may need to include vitamin D supplementation. This project is a first vital step towards developing an effective falls prevention intervention for the large numbers of Australian stroke survivors, which currently does not exist.
Long Term Sequelae Of Acute Kidney Injury: Identifying The Optimal Model Of Care And Intervention To Enhance Patient Outcome

Summary
Acute kidney injury (AKI) is associated with significant morbidity, mortality and health care costs. It is increasingly recognised as a key driver of progressive kidney disease, and no intervention has been shown to improve the long-term outcome of AKI survivors. This project identifies risk factors for chronic kidney disease, dialysis dependence and death after an episode of AKI, and examines the feasibility, efficacy, and cost-effectiveness of early nephrology review in high risk individuals.
