Summary
Cardiovascular disease is the leading cause of death and imposes an enormous financial and healthcare burden on the Australian community. This project will develop and deliver a novel clinical prediction tool, incorporating retinal vascular imaging and assessment, to improve identification of asymptomatic people who are at high risk of cardiovascular disease at an early stage, allowing implementation of preventative strategies and medical interventions to effectively prevent CV disease.

Summary
Retinal vascular disease is a leading cause of blindness and is currently treated by laser photocoagulation surgery. Although successful, this treatment is associated with serious side effects. Recently, Ellex Pty has developed a novel laser called the 2RT laser that is likely to be effective without the accompanying side effects. This study will allow examine the effect of the 2RT laser in animal models of retinal vascular disease so as to complete preclinical development of this laser.

Summary
Glaucoma is a major cause of blindness in our community. The biggest risk factor for glaucoma is raised intraocular pressure. However, the exact cause of the disease remains unknown. Through our basic science studies in animals we have discovered that changes in blood flow in the vessels at the optic disk may be involved in the disease process.

The biggest risk factor for glaucoma is raised intraocular pressure. However, the exact cause of the disease remains unknown. Through our basic science studies in animals we have discovered that changes in blood flow in the vessels at the optic disk may be involved in the disease process. In recent clinical trials we discovered that the presence or absence of pulsations in the retinal veins at the disk was both an indicator of severity and progression of glaucoma. This is a major breakthrough because there is no other means of predicting in which glaucoma patients vision loss will develop most rapidly. This information will be very helpful in deciding which patients should have the most agressive treatment to restore normal intraocular pressure. This project seeks to develop a new commercial device to make such an examination easy for any clinical ophthalmologist. The device allows the doctor to examine the vessels at the disk whilst applying slight pressure to the eye to temporarily raise intraocular pressure. A footswitch is pressed when the doctor sees the vessels pulsate. The required force is recorded by a laptop computer and the data stored along with the patients details. Now we have confirmed the ability of such a measurement to predict the rate of visual field loss in glaucoma, such a measurement will become much more widespread in clinical ophthalmology, offering a new and large scale opportunity for such instrumentation. Our device will be easy to operate, more comfortable for the patient, and will be of major diagnostic value in glaucoma clinics worldwide.Read moreRead less
Development Of A Slit Scanning Laser Ophthalmoscope As A Screening Tool In Glaucoma Diagnostics

Funding Amount
$195,830.00
Summary
Glaucoma is typified by progressive optic disc cupping and loss of fibres with consequent characteristic field defects. Direct imaging of the retina and quantitative assessment of such images greatly increases early diagnosis of this blinding disease. The proposed device, a laser line scanning ophthalmoscope, could support non-invasive imaging to obtain 3-D information in a simple and cost effective way. This could provide objective clinical parameters to support the decision making process.

A transplant of bone marrow or other source of blood stem cells from a donor is often used to treat leukaemia patients whose disease has failed to respond to chemotherapy. The Mater Medical Research Institute has developed a world first dendritic cell depleting therapeutic antibody which may open a new strategy for the control of acute graft versus host disease, which is a very common and often fatal complication of bone marrow transplantation.

The Mater Medical Research Institute has developed a world first dendritic cell depleting therapeutic antibody which may open a new strategy for the control of acute graft versus host disease, which is a very common and often fatal complication of bone marrow transplantation. The new antibody treatment is also likely to be useful for the prevention of rejection in solid organ transplantation. If successful, it will selectively control graft versus host disease, without compromising the essential anti-viral immunity and desired anti-leukemia activity of the graft.Read moreRead less

We have discovered two molecules from pineapple stems that show anti-tumour activity in laboratory studies. One molecule, called ananain, blocks a cancer causing protein called Ras, which is defective in approximately 30% of all cancers. The other molecule, called canizain, stimulates the bodies own immune system to target and kill cancer cells. The proposed research seeks to provide proof of concept of the use of ananain and canizain as drug development targets.

The proposed research seeks to provide proof of concept of the use of ananain and canizain as drug development targets. Once this early proof of principle phase has been completed, we believe that ananain and canizain would be extremely attractive targets for further investment by a major pharmaceutical company.Read moreRead less

In the 21st century new cancer drugs will more effectively destroy malignant tumour cells without damaging normal cells. The R and D herein will value-add to our discovery of a new class of potent and orally active anti-tumour drugs that possess unusually high selectivity in acting on cancer cells without killing normal human cells. Our current proof of concept will be turned into a drug development candidate that will improve our negotiating position with commercial partners.Read moreRead less

Summary
Cancer is the second commonest cause of deaths in our community. Unfortunately, treatment often fails or causes unwanted side effects. This proposal seeks to discover and develop a novel class of anti-cancer drugs that act by directly activating programmed cell death (apoptosis). The Bcl-2 proteins are key regulators of cell death and by exploiting knowledge about these prime targets for cancer therapy, we aim to discover drugs that are potentially of considerable medical and commercial value.
