Summary
Myopia affects about half the world's population with recent studies suggesting epidemic proportions among some Asian schoolchildren though we are not seeing this in Australia. Costs associated with detection, monitoring and optical correction of low and high myopia are huge. High myopes (15% with > 6D) also have a greatly increased risk of blindness between the ages of 30 and 50 years due to secondary disorders associated with impaired fluid balance (retinal and choroidal oedema, macula oede ....Myopia affects about half the world's population with recent studies suggesting epidemic proportions among some Asian schoolchildren though we are not seeing this in Australia. Costs associated with detection, monitoring and optical correction of low and high myopia are huge. High myopes (15% with > 6D) also have a greatly increased risk of blindness between the ages of 30 and 50 years due to secondary disorders associated with impaired fluid balance (retinal and choroidal oedema, macula oedema, retinal detachment and glaucoma). Currently there is no accepted pharmaceutical treatment for myopia though our studies in chick have provided the theoretical rationale and experimental data for a potential therapy and patent. This patent is now at the PCT stage and attests that changes in the abundance of the ions of the subretinal space control fluid movements across the retina to choroid and can be modulated therapeutically by diuretics to control fluid flow and hence axial growth and myopia. This application aims to take our current knowledge about fluid control in myopic chick into a mammalian model prior to preclinical trials in monkey. We anticipate it will take 1 year to establish the feasibility of diuretic control of experimentally induced myopic refractive errors in guinea pigs and the best drug and best the dosage range. These studies will contribute to the scientific understanding and bring the proposed pharmaceutical therapy for myopia in adults and children to a point of full commercialization. We believe that the results found in chick will have significance for early and late-onset myopia in humans as it is highly likely that the same mechanisms of ocular growth regulation operate throughout life.Read moreRead less
Innovations For Better Cardiovascular Prevention In Primary Care

$294,285.00
Summary
The goal of this project is to take a new concept for cardiovascular disease management through the proof-of-concept stage and deliver a novel model for cardiovascular disease management. When proven, the application of this new process for service delivery will provide a low-cost way of closing the gap between guideline recommendations and current management of vascular disease in Australian primary care settings.
A Novel Vaccine Platform For Trimeric Envelope Proteins: HIV-1 Envelope

Summary
Vaccines are urgently needed for the prevention of HIV/AIDS. The design of this vaccine candidate is based on the display of HIV-1 envelope spikes using a related primate retrovirus envelope with a more stable assembly to anchor the the spikes in a particle.
Performance And Safety Testing Of The BioQ Cardiac Assist System In A Chronic Ovine Heart Failure Animal Model

Funding Amount
$142,800.00
Summary
This proposal will test a novel cardiac assist system in safety and performance studies using a chronic sheep heart failure model. This device has been tested in cardiovascular simulators and in an acute animal model showing attractive proof-of-concept data. Specifically, the device increased left coronary artery blood flow and reduced aortic pulse and mean pressures using our novel self-powered fully implantable stand alone device, a potential therapy treatment for heart failure.

Summary
Preterm birth (ie birth before the 37th week of gestation) is the most significant problem facing contemporary clinical obstetrics in the developed world and occurs in approximately 5% to 12% of all deliveries. Being born too early is the major cause of perinatal morbidity and mortality. Data from Australia indicate that each year, more than 17,000 babies will be born prematurely. Of these infants, over 10,000 will suffer respiratory complications and about 1300 will die during the first 21 days ....Preterm birth (ie birth before the 37th week of gestation) is the most significant problem facing contemporary clinical obstetrics in the developed world and occurs in approximately 5% to 12% of all deliveries. Being born too early is the major cause of perinatal morbidity and mortality. Data from Australia indicate that each year, more than 17,000 babies will be born prematurely. Of these infants, over 10,000 will suffer respiratory complications and about 1300 will die during the first 21 days of life. The sickest and most premature of these infants require admission to a Neonatal Intensive Care Unit in a tertiary hospital. Aside from the medical implications of premature delivery, there is also a considerable fiscal challenge to society. While treatments for the prevention of labour have improved considerably over the past decade, current screening tests of preterm labour (ie Fetal Fibronectin test) are unreliable and have poor positive predictive values. The principal objective of this project is to develop and deliver a multiplex assay for the prediction and diagnosis of human preterm labour. Through the successful application of our own proteomic discovery programmes using both ovine and human cervico-vaginal fluid samples, we have identified several new protein markers of labour. Having completed this Phase 1 biomarker trial and established proof-of-concept, we are now well positioned to initiate a Phase 2 biomarker trial to determine reliable estimates of assay sensitivity and specificity. This project targets the development of a new diagnostic to meet a recognised market gap. Delivery of such a test will create a new market in pregnancy-based clinical diagnostics and significantly impact on improving health care and quality of life for many preterm babies. Should the project be completed as detailed and mitigate some of the risk of commercial development, it would then be realistic to seek substantial funding from the private sector.Read moreRead less
Commercialisation Of A Glycoprofiling Diagnostic Kit And Novel Therapies For Biofilm Related Respiratory Disorders

Summary
Our preliminary studies have shown that a group of patients who suffer from chronic inflammatory disease and have bacterial biofilm identified on their mucosa have worse outcomes even after surgery. We have shown that they lack certain small protein and sugar molecules on their respiratory lining. We aim to use this technology as a diagnostic tool to aid the doctor in prescribing the appropriate treatment for these patients to prevent bacteria regrowing in their respiratory tract.
