Summary
Capsaicin, the active ingredient of hot chillies, and other pungent plant extracts have been used for millennia to relieve minor pain. We now know that these agents produce pain relief (analgesia) by numbing the very nerve cells (neurons) which transmit pain signals to the brain. The unique analgesic properties of vanilloids may have a place in modern medicine, giving relief to sufferers of certain types of chronic pain (e.g., neuropathic pain) which are not responsive to morphine-like analgesic ....Capsaicin, the active ingredient of hot chillies, and other pungent plant extracts have been used for millennia to relieve minor pain. We now know that these agents produce pain relief (analgesia) by numbing the very nerve cells (neurons) which transmit pain signals to the brain. The unique analgesic properties of vanilloids may have a place in modern medicine, giving relief to sufferers of certain types of chronic pain (e.g., neuropathic pain) which are not responsive to morphine-like analgesics. Indeed, the promise of more potent and less pungent vanilloid analgesics has led to the discovery of numerous naturally-occurring and synthetic vanilloids. However, although the neurons which convey information regarding blood pressure and the oxygen content of arterial blood to control centres in the brain stem are also stimulated by vanilloids, the central (brain stem) actions of vanilloids on blood pressure and respiration have not been investigated in detail. Thus, the aim of this project is to describe the characteristics of vanilloid receptors in the brain stem, determine the acute and chronic effects of naturally-occurring and synthetic vanilloids on blood pressure and respiration, and elucidate the role played by other neurotransmitter chemicals in the actions of vanilloids. The results of these studies will have major implications in the future use of vanilloids as analgesics.Read moreRead less
Neural Control Of Human Respiratory Muscles In Health And Disease
Funder
National Health and Medical Research Council
Funding Amount
$450,132.00
Summary
This research examines how human inspiratory muscles that ‘pump’ air into the lungs are controlled in health and disease. We will study the interaction between automatic and voluntary control of breathing, about which very little is known. The control of breathing in patients who breathe against an inspiratory load (eg. asthma) and mechanically ventilated patients will be a focus of this research. Outcomes include better understanding of the control of breathing and improved patient care.
How Neural Impairment Affects Respiratory Motor Function In Chronic Obstructive Pulmonary Disease And Healthy Ageing
Funder
National Health and Medical Research Council
Funding Amount
$762,797.00
Summary
With chronic obstructive pulmonary disease (COPD) and ageing, respiratory muscles are weak and the mechanics of the chest and lungs are altered. Our proposal will examine the contribution of impaired neural control to muscle weakness with the aim to identify new targets for therapy to reduce respiratory morbidity in ageing and patients with COPD.
Development Of An Effective Therapy For Cheyne-Stokes Breathing In Heart Failure.

Funding Amount
$604,030.00
Summary
During sleep, patients with heart failure often exhibit a cyclic pattern of breathing in which a period of regular breathing alternates with a period when breathing ceases. This breathing pattern is associated with increased mortality and reduced quality of life but to date no effective treatment for it exists. We have developed a method to calculate an exact level of carbon dioxide to stabilise breathing in each individual, offering the prospect of a better night’s sleep and a longer life.
Invasive Assessment Of Pulmonary Vascular Physiology - Novel Methods For Early Detection Of Pulmonary Vascular Disease
Funder
National Health and Medical Research Council
Funding Amount
$274,352.00
Summary
Pulmonary vascular disease (PVD) is a lethal condition characterised by progressive destruction of the lung blood vessels. One major problem with PVD is that diagnosis is often made very late in the illness, when the pulmonary blood pressure rises. This project aims to develop a novel method to detect the early and clinically silent phase of PVD, by assessing the lung's blood vessel reserves. Early diagnosis of PVD will enable earlier treatment thereby improving prospects for treatment.
Assessing a model of the physiological changes at arousal from sleep. Arousals from sleep are common in the elderly and have adverse consequences. This project will investigate a model of the changes in bodily processes (muscle, brain and cardiovascular activation) that occur when humans awaken from sleep.
What Works To Reduce Aboriginal And Torres Strait Islander Smoking? A National Evaluation Of Tobacco Control Initiatives For Aboriginal And Torres Strait Islander People

Funding Amount
$120,603.00
Summary
My study ties in with a large national project that aims to find out what works to reduce smoking among Aboriginal and Torres Strait Islander people. I will look specifically at one tobacco control approach and its effect on steps toward quitting and staying quit in this group. Together with findings from the broader study, this research will provide valuable new information to help reduce smoking, the number one killer for Aboriginal and Torres Strait Islander people.
Investigation Of The Influence Preterm Birth On Lung Structure And Function In School Age Children.

Funding Amount

Summary
Bronchopulmonary dysplasia (BPD) remains the most significant chronic lung complication of premature birth. While some information on the long term respiratory outcomes in BPD exist there are no comprehensive studies linking lung structure, function and respiratory symptoms and relating these changes to neonatal history. Studies of this kind are essential to ensure future healthcare for these children can be planned accordingly.
Patients With Obstructive Sleep Apnoea And Motor Control

Funding Amount
$302,798.00
Summary
Obstructive Sleep Apnoea is a major health concern, affecting at least 4% of the population, associated with obesity, and aging. The symptoms of sleep apnoea are definitively associated with cardiovascular complications. I am focused on understanding how sleep apnoea patients are remodelled with the rewiring of connections between the brain and muscles. Using neurophysiological techniques, this project will study how the anatomy and functional connections of circuits change with sleep apnoea.
Sleep, Telomere Length And Cardiorespiratory Phenotype In 11-12 Year Old Children: Cross-sectional Australian National Population Based Study
Funder

Funding Amount
$84,800.00
Summary
Telomeres are special areas at the ends of our chromosomes that ‘protect’ our DNA as our body cells divide. With ageing, our telomeres slowly become shorter, but the rate at which this happens varies. My project will investigate the associations between poor sleep duration and quality, increased risk of cardiovascular diseases, poor respiratory health and increased vulnerability to viral infections to shorter telomere length.
