Summary
Type 2 diabetes (T2D) is Australia’s fastest growing chronic disease, affecting almost 2 million Australians (who face poor cardiovascular health outcomes). We have discovered an exciting new avenue that may potentially more effectively counteract heart and blood vessel disorders in T2D patients in an acute cardiovascular emergency, of substantial clinical importance.
A Novel Pathway For The Regulation Of Vascular Tone

Funding Amount
$596,550.00
Summary
The regulation of blood pressure is complex involving the nervous system, kidneys and local pathways that generate blood vessel relaxing and constricting factors. We recently discovered a novel local pathway that becomes induced during inflammation and generates a relaxing substance from the amino acid tryptophan. The present project will identify the active substance and characterize how it causes blood vessel relaxation and thus contributes to the regulation of blood pressure.
Does Manipulation Of Arterial Shear Stress Enhance Cerebrovascular Function And Cognition In The Aging Brain?

Summary
Globally, 9.2 million less cases of dementia could result from delaying it by as little as 12 months. We will assess the impact, on artery health and cognition, of a novel exercise intervention involving enhanced patterns of brain blood flow and arterial shear stress during exercise, stimuli which should optimise cerebrovascular health. Given that pharmacological approaches to prevention are ineffective, this project has the potential to address the future impact of this common and debilitating ....Globally, 9.2 million less cases of dementia could result from delaying it by as little as 12 months.

Given that pharmacological approaches to prevention are ineffective, this project has the potential to address the future impact of this common and debilitating disease in Australians.Read moreRead less
Exercise As Medicine For Heart Failure: A Novel Intervention To Improve Outcomes

Summary
Heart failure (HF) is a common, debilitating and expensive disease; prognosis remains poorer than for the most cancers. 30,000 Australians are diagnosed every year and 300,000 live with the HF, at an annual cost of ~$1Billion. Exercise training is effective therapy in HF, because it reverses many of the problems that contribute to the reduced lifespan and impaired quality of life of patients with HF. We will test an exciting new type of exercise that promising greater benefit, at lower risk.
The health benefits of consuming fruits and vegetables can in part be attributed to their high content of polyphenolic compounds such as flavonoids. These substances can improve functioning of blood vessels and have the potential to reduce the risk of heart disease. This project will examine one of the most common flavonoids in the diet to try and understand how it works and better understand the protective effects.
Postprandial Lipid Metabolism In Familial Hypercholersterolaemia: Mechanisms And Effects Of Omega-3 Fatty Acid Ethyl Esters

Summary
Familial hypercholesterolaemia (FH) is the most common genetic condition known to cause premature coronary heart diseaseis (CHD). The increasd CHD risk in FH may be in part due to accumulation of fat in blood. Fish oil supplementation may be a new target, additional to standard best therapy, for reducing CHD risk in FH. Our results will add value to the science behind and clinical therapy for lipid disorders in FH, and will establish a key role for fish oils.
Developmental Origins Of Adult Cardiovascular Disease: Vascular Health In The Raine Cohort

Funding Amount
$1,087,427.00
Summary
The Raine study is a unique long term experiment that has collected extensive pre-birth and childhood data in ~3000 young Australians, who are now 27 years old. We plan to measure the artery health of 1200 of these volunteers and to determine what factors, both before and after birth, influence the presence of early atherosclerosis in humans. This study will guide strategies aimed at early prevention of heart attacks and stroke in humans, by defining the major risk factors.
Taking A Break For Brain Health: Interacting Effects Of Exercise Bouts With Breaks In Sitting Time On Cognitive And Cerebrovascular Function In Overweight Adults

Funding Amount
$775,055.00
Summary
Whether people do or do not exercise or not, there are serious health consequences – including adult-onset diabetes and heart disease – arising from the 7 to 10 hours of sitting that most Australian adults do each day. Exercise helps to delay Alzheimer's disease and other declines in brain function with ageing. This study will test whether, among overweight adults, combining exercise with breaking up prolonged sitting time can improve markers of brain health and mental functioning.

The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis. Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment h ....The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis. Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment has returned glucose levels towards normal.Read moreRead less
The Critical Roles Of Heme Oxygenase-1 In The Response To Ischemia

Funding Amount
$690,593.00
Summary
Heme oxygenase-1 is a protein that recycles our body's iron which itself is essential for life because it is needed for the sensing, transport and use of oxygen we breath. The current project investigates a novel interplay between heme oxygenase-1 and our body’s major response to tissue oxygen becoming limited. By doing so, our project may provide the basis for novel treatments of conditions where arteries are obstructed, such as those that lead to heart attack and amputation.
