Summary
Excessive growth of blood vessels in the eye causes vision loss and can only be treated with lasers or painful and frequent injections into the eye. Vasostatin is a specific inhibitor of angiogenesis and a promising agent for the management of ocular neovascularisation. We will provide pre-clinical evidence that gene delivery of vasostatin-like peptides is an effective therapeutic strategy and it has potential to revolutionize the current ophthalmic care of age-related macular degeneration.
Functional Analysis Of Recently Identified Novel Glaucoma Genes.

Summary
Glaucoma is the commonest cause of irreversible blindness in the world. Recently, through genetic studies in cohorts of blinding glaucoma cases from Australia, our group has found that variants in two genes increase the risk of blinding glaucoma. This project will investigate how these genes contribute to pathological changes in the optic nerve and retina, at the back of the eye, that lead to glaucoma. This knowledge will be useful for developing new strategies to treat glaucoma.
Nanoparticle-based Anti-VEGF Treatment For Ocular Neovascularization

Summary
Diseases like AMD and DR are the leading cause for substantial and irreversible vision loss as a direct effect of pathologic ocular neovascularization and have a significant economic impact on individuals, families, health systems and countries. Nowadays, the treatment requires frequent intravitreal injections of anti-VEGF antibody with all the risks of an invasive intraocular procedure. Nanotechonoly-based drug delivery system will provide a less invasive treatment for this kind of disease.
A System For Measurement Of Vision-specific Quality Of Life Using Item Banking And Computer Adaptive Testing (ViSBank)

Funding Amount
$831,155.00
Summary
When evaluating medical treatments, it is important to consider all effects from the patient’s perspective; their quality of life. This project utilises new technology to develop an adaptable, computerised, internet-based system to measure the effects of eye diseases and their treatments on patients’ quality of life. This system will provide for more accurate, precise and efficient measurement than existing methods.

Summary
This proposal will use novel techniques to explore how defective responses to the threat posed by a collapsing upper airway contribute to the Obstructive Sleep Apnea syndrome, a disease involving repetitive collapse of the upper airway in sleep. Responses to small increases in the resistance to inspiratory airflow will be examined by measuring the small electrcal responses in the brain to these loads, and the response of the muscles responsible for maintaining airway patency to the collapsing fo ....This proposal will use novel techniques to explore how defective responses to the threat posed by a collapsing upper airway contribute to the Obstructive Sleep Apnea syndrome, a disease involving repetitive collapse of the upper airway in sleep. Responses to small increases in the resistance to inspiratory airflow will be examined by measuring the small electrcal responses in the brain to these loads, and the response of the muscles responsible for maintaining airway patency to the collapsing forces induced by these loads, in both wakefulness and sleep. The brain's response to resistive loads will also be evaluated using the techique of functional magnetic resonance imaging, which demonstrates areas of the brain activated by a stimulus.Read moreRead less
Brm And Brg-1 Protect From Ultraviolet Radiation-induced Skin And Ocular Damage

Summary
Ultraviolet radiation within sunlight is the most important environmental hazard to which Australians are exposed. It causes cancers of the skin and eye, in addition to other forms of skin and eye damage. However sunlight also has health benefits such as vitamin D production. To protect our health from the sun we need to understand how it causes damage and the meachanisms involved. We have discovered a new pathway that we plan to study, called Brm and Brg-1, that provides protection from UV.
Cell-selective Deletion Of Brain AT1A Receptors In Hypertension: Effect On Blood Pressure, Increased ROS Production And Inflammation.

Funding Amount
$578,268.00
Summary
Angiotensin is important for normal regulation of blood pressure but is also involved in cardiovascular diseases. Interruption of angiotensin’s actions is a common treatment of these diseases. Functional deletion of angiotensin receptors decreases blood pressure. Surprisingly the site(s) in the body responsible for this decrease are not known. We will examine the role of angiotensin receptors in the brain in the control of blood pressure in health and in cardiovascular disease.
Reduced Baroreceptor Reflex Control Of Heart Rate In Chronic Renal Failure

Funding Amount

Summary
People with kidney disease are more likely to die of heart disease than their ailing kidneys. One reason is because their hearts do not respond properly to changes in blood pressure, as the nerve circuits controlling the heart become dysfunctional. We will examine where and why components of this circuit are unable to respond to changes in blood pressure. This will help guide new treatments to reduce the incidence of heart disease and risk of death associated with kidney disease.
