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.
Dopamine-2 Receptor Antibody In Movement And Psychiatric Disorders

Summary
Autoimmune movement and psychiatric disorders are a common cause of neurological disability young adults and adolescents. We have identified a subgroup of patients whose disease is associated with an autoimmune reaction. Our study will identify the earliest immune responses against the brain in children with autoimmune movement and psychiatric disorders. Identifying these early immune responses will allow early and directed treatments to prevent disability and death in the future.
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

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.
Lipophilic Iron Chelators As Potential Therapeutic Agents In Parkinson's Disease

Summary
The impaired coordination and tremors experienced by the 64,000 Australians with Parkinson’s disease make managing life at work and home difficult. With 240,000 Australians projected to be living with Parkinson’s disease by 2033, the discovery of agents that slow or stop disease progression is urgent. Iron in the brain has been implicated in Parkinson’s disease. In this project, the performance of new low toxicity agents in altering brain iron distribution will be studied as potential drugs for ....The impaired coordination and tremors experienced by the 64,000 Australians with Parkinson’s disease make managing life at work and home difficult.

Calpeptin, And Related Candidates, For The Treatment Of Machado Joseph Disease

Funding Amount
$888,040.00
Summary
Machado Joseph Disease (MJD) is a neurodegenerative disease that causes impaired movement and progressive paralysis, leading to patient death. MJD is inherited within families, including a high number of Indigenous families of northeast Arnhem Land. We have identified a possible treatment for MJD that has positive effects on a small animal model of the disease (zebrafish carrying the human MJD gene). We plan to test this treatment further with the aim of developing a treatment for MJD patients.
Preclinical Relaxin Therapy To Reverse Cardiac Fibrosis And Gain Functional Benefits

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.
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

Funding Amount

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.
