Summary
Coronary heart disease (CHD) due to atherosclerosis (thickening of blood vessels) remains the leading cause of death in Australia, but visualisation of heart arteries usually requires invasive testing. Blood vessels in the eye (retina), can be viewed easily and may be indicative of blood vessel function in the heart and rest of the body. This study aims to explore the relationship between eye and heart blood vessels. Retinal imaging may thus enable earlier detection of patients at risk of CHD.
Pathophysiology Of Focal Human Entrapment Neuropathy

Summary
Neuropathy patients suffer from tingling, pain, numbness, spontaneous muscle contraction and cramp. The symptoms reflect abnormal activation of the nerve involved. It is known that an external agitation can worsen them, like in carpal tunnel syndrome (CTS). This study aims to investigate if changes in function of axonal membrane ion channel play any part in the symptoms. This will be done by comparing axonal membrane ion channel functions of healthy and CTS patients under external stimuli.
Time-domain Analysis Of Right Ventricular-pulmonary Arterial Coupling As A Windkessel And Wave System.

Summary
We seek to determine the number of people affected by pulmonary arterial hypertension (high blood pressure in the lungs) in Tasmania by collecting information from echocardiograms (heart ultrasounds). This is important because the incidence and prevalence is unknown but suspected to be unusually high in Tasmania. Also simultaneous pulmonary arterial pressure and velocity waves will be studied in humans to model pulmonary flow in an attempt to recognise pulmonary arterial hypertension earlier.
Assessment Of The Mechanisms Involved And Severity Of Arterial Disease In Insulin Resistant States

Summary
Type 2 Diabetes is a major risk factor towards atherosclerosis or blood vessel narrowing. This can lead to vascular complications such as heart attacks, strokes and amputations. This research aim to examine the relationship between some of the mechanisms and their contribution towards vascular disease in the progression from normal health, through insulin resistance to diabetes. This understanding will provide diagnostic tools and treatment targets for diabetic vascular disease.
Clinical Features, Neurophysiology And Histopathology Of Peripheral Neuropathy In Children With Mitochondrial Disease

Funding Amount
$56,200.00
Summary
Peripheral neuropathies are frequently associated with mitochondrial diseases in children and cause progressive weakness and gait abnormalities and could result in loss of ambulation. This study aims to characterise the clinical spectrum and range of electrophysiological and histopathological abnormalities in the peripheral nerves of children with mitochondrial neuropathies to provide a resource that enables early diagnosis and implementation of rehabilitative measures.
Coronary Atherosclerosis And Its Relationship With Platelet Activation

Funding Amount
$101,039.00
Summary
Blood clots are critical to the development of heart attacks, which kill many thousands of Australians annually. Platelets are cells in the blood that play an essential role in formation of blood clots, and coronary disease is associated with platelet activation. This research study will investigate the nature of platelet activation in the arteries of the human heart, its relationship to activation of inflammatory cells, and to the severity of narrowings in the arteries of the human heart.
Blood And Blood Product Transfusion In Trauma Resuscitation

Funding Amount
$98,431.00
Summary
Blood is an exceedingly scarce and expensive resource. Massive transfusions place enormous strains on blood banks. There is little consensus and a paucity of evidence on transfusion practice in major trauma. Trauma patients account for a significant proportion of all patients who receive transfusions. This project will assist with the development of more uniform guidelines for transfusion of blood products in major trauma patients based on the best evidence available and current practice.
