Summary
Hand osteoarthritis (OA) is common, but has no treatment. Almost 50% of people with hand OA will have joint swelling (synovitis). The hand joint of people with synovitis are 3.5 times more likely to experience joint destruction within as little as 2 years. Drugs used to treat synovitis may reduce pain and joint destruction. We propose that treating patients with symptomatic hand OA and synovitis with the anti-synovitis drug, methotrexate, will be a major medical advance.

Summary
Our ability to sense, discriminate and interpret touch stimuli underpins some of the most crucial functions of the human hand that relate to object exploration and manipulation. The fundamental mechanism of how nerve impulses generated by tactile receptors are interpreted by the nervous system is not understood. Only by discovering the underlying neural encoding mechanisms can we appreciate the functional impairments in patients and learn to identify them before they become widespread and irreve ....Our ability to sense, discriminate and interpret touch stimuli underpins some of the most crucial functions of the human hand that relate to object exploration and manipulation.

Effective Sensory Rehabilitation After Stroke: Targeting Viable Brain Networks.

Funding Amount
$767,525.00
Summary
New therapies have been developed to help the brain recover after stroke. We will compare brain networks involved in recovery of touch sensation under two new training conditions and in individuals with interruption to different parts of the network. Brain imaging will identify the functional and anatomical connections between brain regions. Our findings will guide therapists in choosing the best therapy for the right individual, based on knowledge of brain networks that have capacity to adapt.
Viral-mediated Modulation Of BDNF Expression In Motor Neurons To Promote The Recovery Of Hand/digits Function In A Rat Model Of Spinal Cord Injury That Impairs Normal Grasping Action.

Summary
This project seeks to lure injured axons towards motor neurons, a process that is essential for the recovery of motor function. BDNF gradients will be created along the injured axons path. Axons will have to elongate to reach the first source of BDNF. They will need to elongate even more to get to the next source of BDNF, hence bringing them each time closer to their lost targets. This gene therapy scenario has the potential to bring gene therapy a step closer for human spinal cord injury.
Innovative Use Of Hydrogel Technology To Recapitulate And Investigate Cardiac Pathology.

Summary
Hypertrophic cardiomyopathy is the leading cause of sudden death in the young. No treatment exists that can reverse or prevent it, primarily because the underlying mechanisms of the disease have not been fully elucidated. I will use innovative hydrogel technology to simulate the disease state. I will use this as a tool to identify the mechanisms involved with development of the disease. This will enable identification of potential therapeutic targets for prevention of the disease.
The Role Of Dynamin In Spermatogenesis, Sperm Maturation And Sperm-oocyte Interactions

Funding Amount
$551,950.00
Summary
Male infertility is an extremely common condition affecting 1 in 20 Australian men. One of the major reasons for this pathology is that the spermatozoa have lost their ability to interact with the egg and penetrate its outer vestments. In this project we shall investigate the role of dynamin in the regulation of these events. This research will provide new and powerful insights into the causes of male infertility, with practical implications for diagnosis and treatment of this condition.
In Vivo Analysis Of The Molecular And Neural Mechanism That Underly An Association Of MiRNAs With Mental Disorders

Summary
Genetic studies on autism, schizophrenia, bipolar disorder and major depression suggest that these disorders affect the formation and maintenance of connections between neurons. A group of brain-specific microRNAs, which are regulatory molecules, are predicted to regulate connectivity. Levels of these molecules are found to be abnormal in brains of patients with schizophrenia. This proposal aims to elucidate the function of these microRNAs in the number of neuronal connections, and early motor b ....Genetic studies on autism, schizophrenia, bipolar disorder and major depression suggest that these disorders affect the formation and maintenance of connections between neurons. A group of brain-specific microRNAs, which are regulatory molecules, are predicted to regulate connectivity. Levels of these molecules are found to be abnormal in brains of patients with schizophrenia. This proposal aims to elucidate the function of these microRNAs in the number of neuronal connections, and early motor behavior in transgenic zebrafish.Read moreRead less

Summary
The motivation for unveiling the normal hormonal and molecular mechanisms involved in the extraordinary vasodilatation associated with pregnancy is that understanding these fundamental processes may provide novel insights into the pathophysiology of preeclampsia and intrauterine growth restriction, as well as potential therapeutic strategies for not only the treatment of these pregnancy specific conditions but also cardiovascular and renal diseases in non-pregnant women and men.
Investigation Of The Mechanisms Underpinning HSPA2 Dysfunction In The Spermatozoa Of Infertile Patients
Funder
National Health and Medical Research Council
Funding Amount
$481,563.00
Summary
Male infertility is an extremely common condition, that is frequently associated with the production of sperm that have lost their ability to recognize the egg. We have shown that this defect is frequently associated with a deficiency in a specific protein (HSPA2). By determining the mechanisms underpinning the loss of HSPA2, this project will provide powerful insights into the causes of male infertility, with practical implications for prevention, diagnosis and treatment of this condition.
Therapeutic Approaches To Circumvent NO• Resistance In The Type 2 Diabetic Heart And Vasculature

Summary
Type 2 diabetes (T2D) is Australia’s fastest growing chronic disease, affecting almost 2 million Australians (who face poor cardiovascular health outcomes). We have discovered an exciting new avenue that may potentially more effectively counteract heart and blood vessel disorders in T2D patients in an acute cardiovascular emergency, of substantial clinical importance.
