Stress-sensing and cytoprotection in ageing and disease. This project aims to unravel the mechanisms responsible for age- and disease-related responses to heart attacks and the efficacy of therapeutic approaches, while deepening our understanding of a novel, potent protective modality effective in aged hearts. This program will provide valuable basic knowledge, leading to more efficacious therapies.
Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index ....Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index in turbid media, including biological tissue in vivo. We propose to apply our novel technique to study tissue calcification, a serious problem in cardiology, by making use of the refractive index contrast mechanism. Calcification of smooth muscle cells and aorta subdermal implant models will be studied aiming for prevention of calcification-associated pathologies.Read moreRead less
InterLACE: International Collaboration For A Life Course Approach To Reproductive Health And Chronic Disease Events
Funder
National Health and Medical Research Council
Funding Amount
$495,965.00
Summary
Cardiovascular disease and diabetes are major chronic diseases among women. This world-leading research combines data from 7 international and 3 Australian studies of womenÍs health. We will investigate the relationship of reproductive health, from menarche to menopause, with the risk of Type 2 diabetes and cardiovascular disease in later life. Findings will support the development of policies and preventive health strategies to reduce the risk of these chronic diseases.
Noval design of a Bi-Ventricular Assist Device (BVAD) Centrifugal Heart Pump as an Implantable Total Artificial Heart. In Australia, 40%(50,797) of all deaths each year are related to heart disease and accounted for 12% (A$4Billion) of total recurrent health expenditure. This innovative research aims at developing a single biventricular assist device (BVAD) driven by a magnetically suspended double-sided centrifugal pump impeller. Current techniques require two implantable devices, thus preventi ....Noval design of a Bi-Ventricular Assist Device (BVAD) Centrifugal Heart Pump as an Implantable Total Artificial Heart. In Australia, 40%(50,797) of all deaths each year are related to heart disease and accounted for 12% (A$4Billion) of total recurrent health expenditure. This innovative research aims at developing a single biventricular assist device (BVAD) driven by a magnetically suspended double-sided centrifugal pump impeller. Current techniques require two implantable devices, thus preventing smaller patients from access to BVAD technology. The expected outcomes will be a significantly small and compact device and provide an alternative to open-heart transplantation, thus helping to alleviate the demand on donor hearts, as well as the strain on the Australian Heath Care System caused by cardiovascular disease.Read moreRead less
Development and evaluation of a remote monitoring system and its application to cardiac rehabilitation and occupational health. This project further develops and evaluates a system developed by the Industry Partner which permits real-time remote monitoring of a person's cardiac activity, position and velocity via GPS, and selected aspects of motion and posture using accelerometry. The study has three aims: to enhance the system's capacity for remote monitoring of human motion and physiology; to ....Development and evaluation of a remote monitoring system and its application to cardiac rehabilitation and occupational health. This project further develops and evaluates a system developed by the Industry Partner which permits real-time remote monitoring of a person's cardiac activity, position and velocity via GPS, and selected aspects of motion and posture using accelerometry. The study has three aims: to enhance the system's capacity for remote monitoring of human motion and physiology; to test its ability to support cardiac rehabilitation for those unable to access hospital-based programs; and to evaluate its application to the monitoring of workloads in physically demanding tasks associated with cardiovascular ill-health and musculoskeletal injury.Read moreRead less
Enhancing Erythropoietin Therapy In Ischaemia-reperfusion Injury Of Heart And Kidney

Summary
Heart attacks and kidney disease from a lack of blood flow are common causes of morbidity and have poor treatment options. Erythropoietin (epo) is a useful new treatment, but there remain some caveats to its use in humans: eg. it may cause excessive scarring during repair. Use of epo with an anti-inflammatory drug may decrease scarring and provide benefit to long-term health. We plan to carefully define the biomolecular pathways of injury and repair, to better plan this therapy for human use.
From genes to organ function: understanding how heterogeneity in tissue modulates cellular behaviour in the heart. New computational and software engineering approaches are developed to model the electrophysiological variability of the heart and the mechanisms inducing arrhythmias. A significant outcome is a set of practical tools vital to cardiac research that provide medical specialists the ability to test hypotheses on low-cost powerful computing hardware.
Toll-like receptors in infectious and inflammatory diseases: the double-edged sword of innate immunity. The innate immune system is the first line of defence against invading microorganisms. This project will explore the role of specific innate immune genes in the control of infections and the development of inflammatory diseases.
The function of menin in mammalian development. This project aims to determine the role of a ubiquitous transcriptional co-regulator, menin, in mammalian development. Mice that lack menin through targeted deletion of the gene die during embryogenesis, but the cause is unknown, although is likely to be due to the abnormal expression of genes usually regulated by this factor. We will determine which genes are inappropriately expressed and responsible for the accompanying developmental defects. Thi ....The function of menin in mammalian development.

Left-right patterning of the heart. This project aims to investigate how the heart responds to left-right (LR) signals, which tissue is dominant in this response; determine tissue intrinsic factors at play, and determine whether we can manipulate this. Expected outcomes include fundamental information about how organs are patterned.
