Respiratory failure at birth is a major cause of death and disease in newborn infants. At birth the airways must be cleared of liquid to allow the inhalation of air, but, little is known about the process of lung aeration, because it has not been possible to observe or measure it. We have developed imaging and analytical techniques to observed and measure lung aeration. We will determine ventilation procedures that promote uniform lung aeration and minimise lung injury in ventilated infants.
Synchrotron X-ray Assessment Of Airway Surface Physiology For Cystic Fibrosis

Funding Amount

Summary
We seek a cure or long-lasting therapy for the fatal airway disease in cystic fibrosis. Disease is caused by a shallow and dehydrated airway surface liquid (ASL), allowing bacteria to infect the lung. We can introduce a corrective gene into mouse airways where it can be effective for over 1 yr, but no fast, accurate and non-invasive measurement exists to test if treatments are successful. We will develop methods using synchrotron light to directly measure ASL depth changes in live mouse airways.
Ventilation Heterogeneity And Airway Remodelling In Asthma

Funding Amount
$522,586.00
Summary
Asthma is a common and important as a cause of significant symptoms and even death. Associated with asthma is narrowing and stiffening of the arways which causes uneven ventilation of the lungs and reduced lung function. We have developed a new technique of imaging the lungs, as well as new lung function tests which measure uneven ventilation and stiffening of airways. This will help us design better medications, and help predict those who are at risk or severe asthma and death.
The Impact Of Outdoor Aeroallergen Exposure On Asthma Exacerbations In Children And Adolescents

Summary
Asthma is a chronic condition usually diagnosed in childhood and an important public health concern. We do not fully understand what triggers an asthma attack, although outdoor pollen and moulds may be important. This project will establish the relative importance of pollen and moulds in triggering asthma attacks among Australian children. It will fill gaps in our knowledge of environmental triggers of asthma. Such knowledge will improve asthma management and ultimately public health.
Restoration Of The Nigrostriatal Pathway In The Parkinsonian Brain

Summary
Many obstacles exist for cell transplantation in Parkinson's disease; namely poor restoration of the host brain circuitry due to incorrect graft placement. This results in incomplete motor function and unwanted side effects. Through iterative studies we endeavor to restore this circuitry by placing grafts in the appropriate location and promoting their survival and growth-integrations. This will require: optimizing the donor tissue and exposure of the graft to growth stimulating factors.
The Role Of Angiotensin Converting Enzyme 2 In Diabetic Complications

Summary
Most heart attacks and strokes arise from narrowing of the arteries. This process is regulated by a number of hormonal pathways. One of the most important is the renin angiotensin system. Our group has demonstrated important changes in this pathway which play a pivotal role in regulating the development of atherosclerosis and its response to treatment. It is predicted that these studies will provide critical information to develop innovative treatment strategies for cardiovascular disease.
Salt And Cardiovascular Disease: Does Acute Salt-Sensitivity Convey Greater Cardiovascular Risk?

Funding Amount
$597,578.00
Summary
Salt intake of Australian adults is 10X more than required. Further, salt intake in very young children is alarmingly high secondary to high consumption of salty snacks and processed food. High dietary salt intake has been associated with increased cardiovascular disease and death. We will examine the cardiovascular risks for adults and children on a high salt diet and examine whether switching to a low salt diet ameliorates the high blood pressure and heart disease caused by high salt diets
Finding The Genetic Causes Of Asthma: The Australian Asthma Genetics Consortium (AAGC)

Funding Amount
$1,697,639.00
Summary
Asthma is a major burden on individuals and health systems. Despite many decades of research, no major effective new treatments for asthma have emerged recently. We will establish a large international consortium to systematically test nearly all known human genes to identify those that influence asthma susceptibility. We expect to identify pathways not previously implicated in asthma and so lead to a potential breakthrough in the development of more effective treatments.
A Multicentre Randomised Clinical Trial Of Physical Activity For The Treatment Of Patients With Alzheimers Disease

Funding Amount
$773,752.00
Summary
The number of older adults living with Alzheimer's disease (AD) will increase from 26.6 million to 106.2 million by 2050. In the absence of curative treatment options it is important to focus on non-pharmacological interventions such as physical activity. We propose to investigate whether a home-based physical activity program of 24 weeks for patients with AD can successfully decrease the rate of cognitive and functional declince and improve quality of life and psychological well-being.
Mechanisms Of Infection Triggered Renal Vasculitis

Summary
Kidney disease, including glomerulonephritis, is an important cause of ill-health in Australia. Some forms of kidney inflammation are linked to infection, but we don�t understand why. This project explores products from bacteria, particularly S.aureus, to work out how bacterial infection affects a form of kidney inflammation - ANCA-associated glomerulonephritis. It will establish how infection related signals activate local and immune cells, and define links between infection and the disease.
