Optimising the spring in your step to enhance footwear design. This project aims to examine how the nervous system adjusts the mechanical function of our feet across a spectrum of speeds, from slow running through to maximal effort sprinting. The proposed research will explore how the nervous system controls the function of the foot to meet the ever-varying demands of locomotion in the real-world. Expected outcomes of this project are to determine if running shoes help or hinder the natural spri ....Optimising the spring in your step to enhance footwear design. This project aims to examine how the nervous system adjusts the mechanical function of our feet across a spectrum of speeds, from slow running through to maximal effort sprinting. The proposed research will explore how the nervous system controls the function of the foot to meet the ever-varying demands of locomotion in the real-world. Expected outcomes of this project are to determine if running shoes help or hinder the natural spring-like function of the foot. It will explain a conceptually novel design allowing shoes to support our feet, whilst harnessing the energetic benefits of the foot's spring-like function. This research has the potential to revolutionise athletic footwear design and has direct implications for enhanced performance in running athletes.Read moreRead less
Motor Functioning In Young People With Attention Deficit Hyperactivity Disorder – Combined Type: A Three-dimensional Motion Analysis Study.

Summary
Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development. The first objective of this study is to use 3D-motion analysis to ‘probe’ the underlying brain dysfunction which characterises ADHD-CT. The second objective of this study is to improve our understanding of the link between movement problems, and (a) injury proneness, and (b) social-communicative problems, in children with AD ....Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development.

Ocular Motility In Autism And Asperger S Disorder: Dissociation Of Motor Deficits.

Funding Amount
$131,235.00
Summary
We will use ocular motor technology to investigate motor dysfunction in autism and Asperger's disorder, to advance our understanding of the neurobiological bases of these disorders. This will help clarify whether neural networks are differentially disrupted in these disorders, as our previous clinical research suggests. This dissociation and the subsequent development of an ocular motor clincal screen may improve diagnosis, and potentially treatment, of these devastating conditions.
Platelets are key blood elements that are essential for the prevention of bleeding in response to injury or infection. Overactive or spontaneously active platelets cause thrombosis and blood clot formation. My laboratory has identified new physiological pathways of activation of platelet metalloproteinases, the enzymes that regulate surface levels of the prothrombotic platelet receptors. By understanding this mechanism of receptor regulation, we can uniquely target platelet receptors in people w ....Platelets are key blood elements that are essential for the prevention of bleeding in response to injury or infection.

My laboratory has identified new physiological pathways of activation of platelet metalloproteinases, the enzymes that regulate surface levels of the prothrombotic platelet receptors.

Regulation Of Receptors That Control Platelet Function Under Shear Stress

$507,273.00
Summary
Specialized human blood cells that control blood loss and clotting (platelets) are currently difficult to test in the clinical laboratory, meaning patients are at risk of excessive bleeding or serious clot formation during disease or treatment. The aim of this proposal is to use our new reagents and assays to develop more reliable methods for evaluating relative bleeding or clotting risk in individuals.
Autoimmune-based thrombocytopenia can be a life-threatening adverse event associated with viral load, surgery, drug therapies or the use of the anticoagulant, heparin. This grant will define mechanisms of anti-platelet antibody-dependent platelet activation and assess shedding of platelet-specific glycoprotein (GP)VI as an immediate consequence of this activation, provide a new strategy for evaluating risk of thrombosis in HIT.
The Role Of Duffy And PF4 In The Platelet Killing Of Malaria Parasites.

Funding Amount

Summary
Platelets in the blood can kill the Plasmodium parasite, which lives inside red blood cells and causes malaria. Platelets bind parasite-infected red cells and release a molecule that is toxic to the parasite. This project will study why a red cell molecule called Duffy is also needed for this function of platelets. Most Africans carry a gene for Duffy that stops its expression in red cells, and may therefore be more susceptible to malaria because their platelets cannot kill the malaria parasite.
Mechanisms And Therapies In Cardiovascular Disease

Summary
Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide. The molecular and cellular processes underlying atherosclerosis, vascular injury and thrombosis are highly complex and not well understood. A multifaceted approach is needed to effectively address these key challenges. This Program brings together world experts in these areas to interrogate gaps in our basic understanding of CVD, and to develop novel therapies for CVD patients by exploiting ....Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide.

Estimating And Alleviating The Impacts Of Age-Related Sensory Decline

Funding Amount
$323,767.00
Summary
Sensory loss and dementia disproportionately affect older adults, often co-occur, and are the two leading contributors to disability burden among older Australians. This research will investigate the consequences that hearing and vision loss have for older adult health and wellbeing, informing strategies to reduce the disability burden of age-related sensory loss. These impacts include cognitive decline and dementia, mental health, quality of life, disability and independent living.
Structural And Functional Analysis Of A Cancer-linked Co-regulator Complex

Funding Amount
$729,571.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
