High-resolution Brain Imaging Of Basal Ganglia Function
Funder
National Health and Medical Research Council
Funding Amount
$589,083.00
Summary
This project will develop new methods for high resolution MRI imaging of the human brain. We will assess functions of deep brain areas known as the basal ganglia that play a critical role in movement planning and co-ordination. Dysfunction within the basal ganglia is responsible for the motor impairments seen in people with Parkinson’s disease. In this project, we will examine changes in basal ganglia function and structure that lead to individual differences in movement control and learning.
A Longitudinal Neuroimaging Study Investigating Reorganisation Of Cerebellar-cerebral Networks In Friedreich Ataxia

Funding Amount
$816,908.00
Summary
Friedreich ataxia (FRDA) causes debilitating motor and cognitive deficits. We propose a longitudinal multi-modal magnetic resonance (MR) imaging study to measure different types of tissue in the brain in this disease. We seek to understand how the brain reorganises itself due to cell loss in the spinal cord, cerebellum and cerebral cortex. This study will establish sensitivity of a range of MR imaging measures as potential biomarkers for use in large multi-centre drug trials in this disease.
Effects Of Dual Task Functional Power Training On Falls In The Elderly? An 18-month Community-based Randomised Controlled Trial
Funder

Funding Amount
$669,176.00
Summary
Many falls in the elderly result from an inability to produce an explosive and rapid movement to step quickly when balance is lost, particularly when simultaneously performing other attention demanding (dual task) activities such as talking while walking or negotiating traffic. This study will investigate whether dual task high speed functional training can reduce the rate of falls and improve gait, balance and muscle function under dual task 'real-life' conditions in elderly women at increased ....Many falls in the elderly result from an inability to produce an explosive and rapid movement to step quickly when balance is lost, particularly when simultaneously performing other attention demanding (dual task) activities such as talking while walking or negotiating traffic. This study will investigate whether dual task high speed functional training can reduce the rate of falls and improve gait, balance and muscle function under dual task 'real-life' conditions in elderly women at increased risk of falling.Read moreRead less
Establishment Of A Biomarker To Test Molecular Risk Of Gastric Cancer

Funding Amount
$834,448.00
Summary
Less than 20% of patients live 5 years after a diagnosis of gastric cancer (GC). This is due to the advanced stage at the time of diagnosis. We have no markers to monitor therapy of cancer. This proposal aims to use next generation sequencing to find specific genetic changes in a persons tumour that can be used to monitor therapy. We aim to use the same technology to group patients into high-risk or low risk for development of GC. This will allow specific screening only for those at high-risk.
Structural Basis For Helicobacter Pylori Adhesion To Host Epithelial Cells

Funding Amount
$665,328.00
Summary
The aim of this grant is to understand how the bacteria that cause gastric cancer and ulcers interact with the cells that line the stomach. This information will be used to develop new treatments to combat disease.
Pathologies Of Action Control: Amygdala-striatal Interactions And The Development Of Habits.
Funder
National Health and Medical Research Council
Funding Amount
$431,867.00
Summary
Changes in basal ganglia function, whether produced by neurodegenerative disorders, stroke, injury or disease, can produce pathological changes in action control. This proposal will assess the role of amygdala afferents on basal ganglia structures, most notably the dorsal striatum, in this process. Using an animal model we will compare the role of central and basolateral amygdala inputs to striatum in decision-making, choice and the transition of actions to reflexive, habitual responses.
Towards Evidence-based Care For Rett Syndrome: A Research Model To Inform Management Of Rare Disorders
Funder
National Health and Medical Research Council
Funding Amount
$458,046.00
Summary
Rett syndrome is a rare but serious genetic neurological disorder affecting mainly girls and often complicated by spinal curvature and poor growth. This project will use national register data collected over 16 years to examine change in functional abilities and progression of the scoliosis curve. It will develop guidelines and improve processes to assist with diagnosis and will comprehensively evaluate the surgical treatments used in the management of scoliosis and growth problems.
Volitional And Non-volitional Control Of Human Balance: Normal Physiology And Changes With Ageing
Funder
National Health and Medical Research Council
Funding Amount
$383,066.00
Summary
How does the brain control balance when we stand? Our research shows that two very distinct processes operate to produce distinct postural, perceptual and cardiovascular outcomes. These experiments investigate the neurophysiology that coordinates these systems and what happens with age. The results will fundamentally change views on balance control. Balance problems are common in neurological disorders and old age. Knowing how balance works will improve diagnosis, treatment and rehabilitation.
Vaccinating Against Helicobacter Pylori-induced Gastric Cancer

Funding Amount
$1,088,714.00
Summary
Stomach cancer is the 3rd leading cause of cancer-related deaths. Most stomach cancers result from inflammation due to Helicobacter pylori infection. Most infections are treatable with antibiotics but this does not protect against cancers that develop before infection is diagnosed. Normal vaccine approaches aimed at this infection have been unsuccessful. We have identified a new approach for protecting against stomach cancer by preventing inflammation; this project aims to develop this vaccine.
Understanding The Role Of B Cells In Gastric Cancer For The Design Of New Therapeutic Strategies

Funding Amount
$696,383.00
Summary
Gastric cancer is the 2nd most common cause of cancer-related death worldwide. Our laboratory has previously established clinically relevant mouse model of gastric cancers, and our preliminary results indicate a strong link between B cell tumor infiltration and gastric cancer progression. In this project, we aim to elucidate the role of B cells in gastric cancer and determine whether B-cell targeted therapy alone or in combination with chemotherapy can be beneficial against this malignancy.
