Refining And Testing A Promising New Treatment For Chronic Pain.

Funding Amount
$743,947.00
Summary
Chronic pain costs Australia about 35 billion dollars a year. Recent scientific discoveries show that treatment aimed at correcting problems in how the brain processes sensory input can reduce pain and disability. This project will clarify some key aspects of these problems and use that information to make final adjustments to an already very promising treatment. We will then test the treatment in a definitive and comprehensive clinical trial.
Understanding The Regulation Of HERG Potassium Channel In The Myometrium At The Time Of Labour

Funding Amount
$597,661.00
Summary
We have shown that a potassium channel known as hERG falls precipitously at the time of term labour and that blocking this channel causes powerful uterine contractions. This grant will determine how the expression of this channel is regulated in the myometrium and whether changes in hERG channels also occur in premature labour.
Understanding The Myometrial Transition At Term And Preterm Labour To Guide Tocolysis

Funding Amount
$808,447.00
Summary
This grant seeks to understand how the muscle cells of the uterus transform at the time of labour. We propose that this transformation is organised by enzymes that modify the histones around key genes. We will test if a similar pathway operates in cases of preterm labour. The results will guide the development of new ways of treating premature labour that will use targeted nanoparticles to deliver siRNA directly to the muscle cells of the uterus.
Optimising Future Human Health By Optimising Birth Outcomes

Summary
Laureate Professor Smith received an AM for his research on human pregnancy and contributions to Indigenous maternal health. His research has dramatically expanded in the last 5 years to include stillbirth, viral infections during pregnancy, early detection of renal disease, the development of targeted nanoparticles for delivery of therapeutics to the uterus, and data-linkage to test the impact of antenatal care. His research seeks to optimise the health of pregnant women and their children.
Discovery And Development Of Better Pain Treatments

Summary
Many forms of pain remain poorly treated, leading to significant quality of life and economic losses. This Program grant will discover and characterise new peptides from cone snails and spiders that modulate specific channels in nerves that are critical to the transmission of pain signals to the brain. Using advanced chemical and structural approaches, promising leads will be optimised for potency and stability and evaluated in disease and pathway-specific models of pain to establish their clini ....Many forms of pain remain poorly treated, leading to significant quality of life and economic losses.

THE AUTONOMIC, SOMATIC AND CENTRAL NEURAL RESPONSES TO DEEP AND SUPERFICIAL PAIN IN HUMAN SUBJECTS

Summary
Pain is a subjective experience, the intensity of which can be readily influenced by personal experience. Despite this, pain originating from a particular part of the body will usually be described by all individuals as having similar character. For example, pain arising from the skin is commonly described as being sharp or burning and is usually easy to localise, whereas pain arising from muscle is commonly dull, throbbing and diffuse. In addition to producing sensory changes, pain also evokes ....Pain is a subjective experience, the intensity of which can be readily influenced by personal experience. Despite this, pain originating from a particular part of the body will usually be described by all individuals as having similar character. For example, pain arising from the skin is commonly described as being sharp or burning and is usually easy to localise, whereas pain arising from muscle is commonly dull, throbbing and diffuse. In addition to producing sensory changes, pain also evokes changes in blood pressure, heart rate and motor activity (often in an attempt to remove the source of the pain). The proposed research aims to characterise the cardiovascular and motor patterns associated with pain originating in skin and in muscle and to examine the brain regions that produce these changes. More specifically, microelectrodes will be used to investigate changes in peripheral nerve activity during transient painful skin and muscle events in awake human subjects. In a separate investigation functional magnetic resonance imaging will be used to determine brain sites that are activated by skin or muscle pain.Read moreRead less
This project will test if the ratio of the two different estrogens found in the blood of pregnant women is the critical factor in determining the onset of contractions in the uterus at labour. The studies will also determine the role of a newly discovered receptor for estrogens in allowing powerful contractions at labour. Results will allow development of new treatments to prevent premature birth that block the actions of estrogen at this new receptor or change the ratio of the two estrogens.
Achieving Targeted Delivery Of Drugs To Uterine Muscle In Women For The Prevention Of Preterm Labour

Summary
We have patented liposomes targeted to the uterus, which enable us to deliver drugs specifically to the muscle cells of the uterus, increasing safety. The liposomes can be loaded with drugs that either block or promote contractions, creating a versatile drug delivery system that could treat premature labour or postpartum haemorrhage which are major clinical problems. We seek support to demonstrate their effectiveness in mouse and primate models of preterm labour prior to human studies.
Understanding Persistent Low Back Pain Where It Resides, In The Brain

Funding Amount

Summary
Low back pain is a leading cause of disability amongst Australians. A critical question is why some people get better after hurting their back while others do not. This project examines whether changes in the brain predict low back pain outcome. This information will rapidly advance our understanding of low back pain and has the potential to facilitate the development of novel therapies.
Neuropathic pain is particularly difficult to treat and existing medications have considerable side effects. This project will develop a new set of glycine transport inhibitors that have the potential to provide pain relief without side effects.
