National Centre Of Research Excellence To Improve Management Of Peripheral Arterial Disease
Funder
National Health and Medical Research Council
Funding Amount
$2,618,637.00
Summary
Approximately 15% of adults have blockages or weakness of major arteries in the periphery, associated with impaired quality of life and a high mortality. Significant management deficiencies for these problems include limited diagnostic, prognostic and treatment options, as well as poor adoption of evidence based practice. The proposed national centre will bring together a group of experts in the field to instigate a number of initiatives to improve patient management.
Suppression Of NADPH Oxidase-derived Oxidative Stress By Anti-sense Probes And HDL In Human Vascular Endothelium

Summary
In Australia, coronary heart disease (CHD) causing heart attacks remains the largest cause of death, claiming a staggering 28,000 lives a year. Oxidative stress, resulting from increased production of oxygen free radicals in arteries, is an important cause of CHD, heart attacks and strokes. We seek to understand how such oxyradicals are produced in the key cells that form the lining of all arteries, known as the vascular endothelium.

Oxidative stress, resulting from increased production of oxygen free radicals in arteries, is an important cause of CHD, heart attacks and strokes. We seek to understand how such oxyradicals are produced in the key cells that form the lining of all arteries, known as the vascular endothelium. By using novel DNA-type molecules (known as anti-sense) developed in our laboratory, which block a particular gene causing oxidative stress, we will determine whether this gene is responsible for the formation of oxyradicals in human and mouse cells grown in culture. In addition, we will explore whether this gene is turned on by factors known to be involved in CHD. Finally, we will also investigate whether the good cholesterol known as HDL can act to prevent oxidative stress in human cells, as we discovered it appears to do in living arteries in vivo. If we find it has the same protective effect in endothelium, we will determine how it does this, and which component proteins of the HDL particle are important. This might suggest new treatments to prevent acute events leading to heart attack and stroke, and possibly new applications where damage appears to result from acute oxidative stress, such as in the brain soon after a stroke has occurred. We also have a plan to develop antisense drugs that will target the important gene specifically in the affected endothelium. In addition, we have other specific new drugs that will block this system in arteries. Simultaneously we will be testing the role of this gene in mouse and rabbit models of artery disease, for both our types of drugs might provide valuable new therapeutic agents to target the underlying cause of CHD and not just its symptoms as current drugs do.Read moreRead less
Advancement Of A Personalised Approach To Minimising Infective Complications In Cancer Care

Funding Amount
$265,138.00
Summary
Managing infections in patients with cancer have become more difficult and unpredictable because of new generation cancer therapies. Measuring the response of the immune system (immune profiling) will allow us to predict which patients will develop infection so that action such as vaccination can be taken to reduce their risk. This program will refine immune profiling to personalise infection care for cancer patients and to introduce it into hospital practice.
Signaling Pathways To Enhance Potency Of AMPK-targeting Drugs

Funding Amount
$661,966.00
Summary
Sedentary lifestyles and consumption of high energy foods has led to epidemics of obesity-related metabolic diseases that place enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK) which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Our goal is to improve AMPK drug potency by identifying novel processes that sensitize AMPK to drugs.
UTILITY OF NOVEL BIOMARKERS IN THE PREDICTION OF MAJOR COMPLICATIONS OF TYPE II DIABETES MELLITUS

National Health and Medical Research Council
Funding Amount
$510,639.00
Summary
Diabetes is increasingly common. It can cause a variety of complications, the most serious being heart and kidney disease. The reasons why some patients develop such complications are not fully understood so it is difficult to predict who will be affected. The current project will use samples from a large international study of patients with diabetes to assess whether levels of specific markers in the blood help to predict major complications and clarify why they occur.
Effects Of Replacement And Withdrawal Of Testosterone In Human Males On Muscle, Bone And Fat

Funding Amount

Summary
Male sex hormone or androgen deficiency (AD) is a common, but under-diagnosed condition. AD decreases well being and contributes to muscle weakness, bone fragility and weight gain. Cutting edge technology will be used to help explain how AD may relate to these negative effects, particularly on muscle function. Given the importance of aging, frailty, osteoporosis and obesity, understanding the role of hormones in these conditions may have major implications for prevention and treatment.
Do Exposures Before Conception Influence The Risk Of Asthma In Offspring?

Funding Amount
$688,586.00
Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
Clinical Trial Of A Suprachoroidal Visual Prosthesis For The Profoundly Vision Impaired

Funding Amount

Summary
For 15 years we have been designing a bionic eye. We have made a device called the Phoenix99 and shown in short term animal tests that it is both safe to implant but also that it potentially performs better than any other device in the world. We are requesting funds to complete longer term animal testing of the device and then commence a small human clinical trial to demonstrate the benefits of the technology – specifically that it is able to help blind people navigate without assistance.
Functional Electrical Stimulation Assisted Cycling (eStimCycle):A Novel Intervention To Improve Outcomes In The Critically Ill
Funder
National Health and Medical Research Council
Funding Amount
$868,811.00
Summary
The legacy of critical illness leaves millions of survivors worldwide with long lasting deficits in physical and brain function as well as anxiety, depression and post-traumatic stress disorder. Early rehabilitation may prevent or minimise these effects. This study evaluates the effectiveness of functional electrical stimulation of muscles with assisted in-bed cycling (eStimCycle) on muscle bulk, strength, physical and brain function at hospital discharge, 6 and 12 months.

Funding Amount
$1,366,831.00
Summary
This study will investigate links between reproductive factors and body size of premenopausal women with their risk of major chronic conditions, such as cardiovascular disease, diabetes, and asthma. It builds on two decades of survey data from Australia’s flagship study of women’s health with a new biomedical assessment. Findings will guide the use of indicators of women’s reproductive health as a trigger for early and targeted approaches for chronic disease prevention.
