This project brings together a newly emergent modality of microscopy in the form of 3D X-ray micro-tomography (XRMT) along with leading-edge image analysis to develop breakthrough science in respiratory research aimed at improving the reliability of high resolution computed tomography (HRCT). The project will develop novel 3D lung image segmentation protocols, a stereotactic registration program allowing 3D matching of XRCT and HRCT data sets, and a validation protocol for quantitative HRCT analysis of airway disease. These outcomes will allow wider application of HRCT to non-invasively follow the dynamics of pulmonary function.Read moreRead less
The early osteoarthritis (OA) phenotype. Australia like many other developed countries is undergoing a major demographic shift involving significant growth in the aged population. From both a patient perspective and a societal perspective, research into the underlying determinants of osteoarthritis such as those outlined in this proposal are of great importance to the aged population.

Australia like many other developed countries is undergoing a major demographic shift involving significant growth in the aged population. From both a patient perspective and a societal perspective, research into the underlying determinants of osteoarthritis such as those outlined in this proposal are of great importance to the aged population. Nearly one in five Australians has arthritis; indeed more Australians have arthritis than any other national health priority condition. From an individual point-of-view, the pain and disability due to osteoarthritis (OA) can lead to loss of independence and diminished in quality of life for older adults.Read moreRead less
Brain structure and function of neonates at risk for stuttering. The aim of the project is to determine whether the brain abnormalities that have been found in people who stutter are present at birth. The hypothesis is that the brains of neonates who subsequently start to stutter will differ significantly from those who do not. This is the first project to investigate the brains of infants before they start to stutter.
Advanced imaging technology for measuring pulmonary form and function. Studies of the lung are often limited by difficulties associated with imaging the complex network of airways with conventional techniques. This project will develop novel phase contrast image x-ray imaging technologies to enable quantitative measurements of lung structure and function for studying lung development and assessing lung health.

Summary
Brain networks may reorganize to optimise stroke recovery. However, little is known about brain mechanisms underlying natural and training-induced recovery after stroke, particularly following loss of body sensations. Knowledge of the experiences that may facilitate brain reorganisation is a prerequisite for the development and evaluation of optimal stroke rehabilitation strategies. We aim to provide novel information on the potential benefits of specific training in facilitating reorganisation ....Brain networks may reorganize to optimise stroke recovery. However, little is known about brain mechanisms underlying natural and training-induced recovery after stroke, particularly following loss of body sensations. Knowledge of the experiences that may facilitate brain reorganisation is a prerequisite for the development and evaluation of optimal stroke rehabilitation strategies. We aim to provide novel information on the potential benefits of specific training in facilitating reorganisation of the brain after stroke. Specifically we will: (i) locate areas of brain activity associated with natural and training-induced recovery of touch sensation following stroke and (ii) investigate the relationship between brain activation, sensory recovery and intervening experience. Site and extent of brain activation associated with recovery of touch sensation will be investigated over time using serial functional magnetic resonance imaging (fMRI), a controlled sensory task and clinical measures of recovery. Thirty stroke patients with impaired touch sensation of the upper limb will be studied at 2-6 weeks and 6 months post-stroke to investigate changes in brain activation associated with natural recovery (Study 1). Ten healthy controls will also be studied over 6 months. Those patients who still have sensory loss at 6 months will then receive specific sensory training or placebo intervention to study the effect of training-induced recovery on brain activity (Study 2). The whole brain will be studied and activation sites will be interpreted relative to individual and standard brain maps. We expect that the findings will advance our knowledge of the relationship between clinical recovery, training and neural plastic changes in the brain. This information will provide direction for the development of scientifically based treatments designed to maximise recovery and help identify patients who are likely to show natural recovery and-or benefit from training.Read moreRead less

This project aims to characterise key components of nephrons, the glomeruli and tubules, using magnetic resonance imaging without contrast agents, in combination with Deep Learning and super-resolution techniques. Nephrons, the basic functional unit of the kidney, are critical to the maintenance of the body’s homeostasis. Their number and architecture are critical determinants of kidney function. The expected outcomes are innovative semi-automated nephron visualisation and quantitation tools that enable efficient renal phenotyping. Techniques tailored to widely accessible preclinical research scanners are expected to accelerate research into genetic and environmental factors affecting kidney microstructure in embryonic and post-natal life.Read moreRead less
Investigating Linguistic Factors Associated with Stuttering in Cantonese. The aim of this research is to gain new knowledge about the cause of stuttering. The project is a collaboration between experts in stuttering in Australia and Hong Kong. Despite decades of study, the cause of stuttering is still not well understood.

The aim of this research is to gain new knowledge about the cause of stuttering. The project is a collaboration between experts in stuttering in Australia and Hong Kong. Despite decades of study, the cause of stuttering is still not well understood. Research in English has suggested that changes in emphasis from syllable to syllable can trigger individual moments of stuttering. However, Cantonese is very different from English, being a tonal and syllabic language, and uncovering the linguistic triggers of stuttering in Cantonese will yield new insight into the complex causality of this disabling condition.Read moreRead less
About 1 in 10 Australians have persisting or chronic low back pain. Most are managed in primary care and the most frequently prescribed treatment is exercise. Chronic low back pain remains a major health problem because not all patients respond to each treatment so on average treatment effects are small. At present there are no guidelines to help clinicians select the best treatment for a patient. As a result a lot of time and money is wasted on treatments which ultimately fail to help the patie ....About 1 in 10 Australians have persisting or chronic low back pain. Most are managed in primary care and the most frequently prescribed treatment is exercise. Chronic low back pain remains a major health problem because not all patients respond to each treatment so on average treatment effects are small. At present there are no guidelines to help clinicians select the best treatment for a patient. As a result a lot of time and money is wasted on treatments which ultimately fail to help the patient. We have begun a research program to solve this primary health care problem. We have focussed on exercise because the treatment is widely available in primary care and of modest cost. The program includes basic research to understand the mechanism of action of exercise and clinical trials testing the effectiveness of different types of exercise. The proposed study falls into the latter category, and is a direct comparison of the two most promising types of exercise used in Australia. The study will also identify clinical features that modify treatment effects, a finding that will allow clinicians to identify which type of exercise is more likely to be effective for an individual patient. This study offers a potential solution to a major health problem with enormous economic and social costs.Read moreRead less
