Summary
This project will fund the construction of a clinically deployable prototype device to measure changes in upper airway size and shape in patients with obstructive sleep apnoea. We have recently developed and validated a technique based on endoscopic optical coherence tomography (OCT). Preliminary in vivo studies have been performed in the human upper airway and the results published.

We have recently developed and validated a technique based on endoscopic optical coherence tomography (OCT). Preliminary in vivo studies have been performed in the human upper airway and the results published. To our knowledge, this is the only such system world-wide capable of making these important measurements. The technique has wide commercially applicability as it can be used to measure the internal dimensions of any hollow organ system.Read moreRead less
Development Of Quantitative Tools For Assessment Of Regional Cardiac Function By Echocardiography

Summary
The application of ultrasound imaging to the assessment of cardiac function (echocardiography) is an invaluable tool for the assessment of patients with known or suspected cardiac problems. The assessment of contraction in each region of the heart is probably the most important of the reasons for doing this test, as regional function is disturbed in patients with coronary artery disease, which is one of the most common causes of death in Australia. The problem is that this analysis is currently ....The application of ultrasound imaging to the assessment of cardiac function (echocardiography) is an invaluable tool for the assessment of patients with known or suspected cardiac problems. The assessment of contraction in each region of the heart is probably the most important of the reasons for doing this test, as regional function is disturbed in patients with coronary artery disease, which is one of the most common causes of death in Australia. The problem is that this analysis is currently completely subjective, and the reliability of the tool is based upon the availability of an experienced observer. This is particularly a problem in rural Australia, as most specialists with expertise in this modality work in the capital cities, and especially a problem in Queensland, where fewer than half of the population live in the capital. The cardiac imaging group at the University of Queensland have been working in collaboration with GE-Vingmed Ultrasound to develop a quantitative technique for the assessment of regional cardiac function since 1997. This collaboration has been the source of a number of published papers and presentations at international meetings. Our group is considered to be a world leader in the field and our industry partner is clearly the most focused of its competitors in addressing this problem. This submission seeks to address several remaining problems. The data thus far addressed function during stress, when the condition of most patients is similar. Tissue velocities are more variable at rest, and a more sophisticated approach is required to accurately measure the lower velocities in the resting state. This research plan seeks support for the development of a new, high frame-rate acquisition that would facilitate the examination of velocities relative to each other, so that translational motion of the heart does not influence the reading. This new method would then be validated against other techniques for assessing function and disease.Read moreRead less
Development Of Small Molecule IRAP Inhibitors For Treating Memory Deficits

Funding Amount
$369,898.00
Summary
We have identified a series of small molecule compounds based on their ability to inhibit the catalytic activity of a protein, IRAP using a computer model of IRAP to screen chemical libraries. This research proposal aims to investigate the properties of these compounds and their ability to treat Alzheimer's dementia. At the conclusion of this project, we will have 2 families of lead compounds suitable for development into a new class of therapeutic agents for treating Alzheimer's disease.

This research proposal aims to validate that this family of compounds have memory-enhancing properties by acting specifically on IRAP. At the conclusion of this project, we will have elucidated important information on the specificity of the memory effects and the structure activity relationship of this family of compounds. We will have identified and characterised a lead compound for development into a new class of cognitive enhancers.Read moreRead less

Summary
Due to the growing incidence of obesity within Australia, use of computer technology may be a method of targeting these people by increasing access to dietary services. Currently available dietary software in the Australian context only allows analysis of nutrient information.

Currently available dietary software in the Australian context only allows analysis of nutrient information. Thus when a dietitian sees a patient they must manually translate food intake to nutrient information, a largely time consuming exercise. DietAdvice is a website that was developed for people to enter in their own food intakes. The food information is sent to a dietitian who develops individualised dietary advice for them. A pilot study of the website has already found it to be feasible in the primary healthcare setting. Tested for 12 months the website was used by 224 patients from GP practices in the Illawarra region of NSW. Approximately 73% of patients were overweight and patients with a high BMI were 1.88 times more likely to use the website in the comfort of their home. Further research about the website however was needed. The research to follow on from the pilot study will aim to refine the DietAdvice website, leading towards its commercialisation for dietitians in clinical practice. The research will be broken into 3 phases. Phase 1 will involve a usability test of the website, assessing the underlying algorithms and testing it with dietitians in private practice. Phase 2 will see volunteers using the website on multiple occasions after being given pre-weighed amounts of food to eat. This will determine how reliable and accurate the information is; and phase 3 will evaluate whether the website is cost effective and if it increases accessibility of health services especially in rural areas. By confirming these attributes there will be a sound basis to commercialise the product.Read moreRead less
