Structural Studies Of Thyroid Peroxidase, An Autoantigen In Autoimmune Thyroid Disease
Funder
National Health and Medical Research Council
Funding Amount
$386,423.00
Summary
This proposal is aimed at determining the three dimensional structure of Thyroid Peroxidase, a protein found in the human thyroid gland that is important in the production of the hormone thyroxine. Thyroxine is involved in controlling the rate of metabolic processes in the body and influencing physical development.
Local Sleep In The Awake Brain: An Underlying Cause Of Neurobehavioural Deficits In Sleep Apnea?

Summary
Obstructive sleep apnea (OSA) is a common sleep disorder which significantly impacts daytime functioning leading to excessive sleepiness, and problems with attention and thinking. Currently, the causes for cognitive impairment in OSA (including attentional lapses and performance deficits) are poorly understood. In the awake state, groups of neurons can briefly go “offline” as they do in sleep. These periods of “local sleep” may explain impaired task performance in OSA.
A Novel Approach To Streamlining The Diagnosis Of Primary Aldosteronism

Funding Amount
$269,463.00
Summary
This study will assess a new clinical test used to diagnose a potentially curable form of high blood pressure called primary aldosteronism (PA). If successful, the test will greatly streamline and simplify the diagnosis of this condition, with the potential for enormous cost savings and a markedly increased rate of diagnosis of patients with PA who can then benefit from optimal treatment and improved quality of life.
Schizophrenia is a serious and debilitating psychotic illness often characterized by delusions: fixed, false beliefs that preoccupy the patient and affect behaviour, and which are resistant to current drug treatments. This project investigates dysfunctions in belief mechanisms that allow delusions to form and be maintained. This will help clinicians design more effective programs of cognitive behavioural therapy for psychosis by allowing more focussed interventions to reduce delusions.
Investigating The Mechanisms That Increase Nerve-evoked Vasoconstriction Following Spinal Cord Injury
Funder

Funding Amount
$372,547.00
Summary
People with spinal cord injury not only lose control of their arms and legs but also lose control of their bladder and bowel. They also have poor control of blood pressure and an overfull bladder or bowel can lead to dangerously high blood pressure. In this project, we are investigating how this abnormal high blood pressure is generated. The aim is to develop treatments which target the mechanisms which increase the blood pressure responses elicited by the bladder and bowel.
Preclinical Relaxin Therapy To Reverse Cardiac Fibrosis And Gain Functional Benefits
Funder

Funding Amount
$724,754.00
Summary
Cardiac fibrosis is a key factor promoting heart disease and onset of complications including arrhythmias and heart failure. There is urgent and unmet need of drugs that can reverse fibrosis. By documenting anti-fibrotic action of a peptide hormone relaxin, CIA and his team will test therapeutic effect of relaxin in heart disease models focusing on fibrosis-reversal and functional gain, particularly arrhythmias. This work would promote development of relaxin as a new cardiovascular drug.
Understanding The Control Of Brain Development And Endocrine Function Through Central Regulation Of Gene Transcription

Summary
Intellectual disability affects about 2% of the Australian population. The identification of genes underlying a number of intellectual disability disorders has brought about great clinical advances. However, our knowledge of how these genes influence processes of brain development and are important for intelligence is very limited. We propose to study the function of PHF6, the gene mutated in the Börjeson-Forssman-Lehmann intellectual disability syndrome, during brain development.
Cardiovascular disease is a leading cause of death in Australia, accounting for 36% of all deaths in 2004-05. Diseased blood vessels are its most common form, and the underlying process is atherosclerosis. Atherosclerosis is characterised by plaque formation in blood vessels. Plaque formation is problematic, and may lead to blood vessel blockage. We aim to identify novel targets that prevent plaque formation.
Pharmacological Inhibition Of IRAP As A Novel Antifibrotic Strategy

National Health and Medical Research Council
Funding Amount
$1,036,370.00
Summary
There are very few treatments that can reduce heart stiffening, called fibrosis, which is seen in patients with high blood pressure or in patients who have had a heart attack. This project will test new drugs that we have developed that act by a unique mechanism to reverse or prevent cardiovascular disease in patients with poorly-functioning hearts and blood vessels.
Optimising Balance Function In Vestibular Schwannoma
Funder
National Health and Medical Research Council
Funding Amount
$271,817.00
Summary
This project examines human balance function in subjects with vestibular Schwannoma, a slow growing tumor that presents with hearing loss and imbalance. We will measure inner ear balance function using 2 new non invasive tests called the video head impulse and the vestibular evoked myogenic potential. We will seek test parameters that predict tumor growth, explore reasons for post surgical imbalance, develop and validate home-based rehabilitation methods to optimise balance after surgery.
