Summary
This project seeks to provide fundamental new information about the means by which neurotransmitter receptors, which mediate fast synaptic neurotransmission, operate. This knowledge is important since the Cys-loop family of ligand gated ion channel receptors are responsible for a wide range of neuronal signalling and the control of both excitatory and inhibitory receptors. The Cys-loop receptors are modulated by both therapeutic drugs (eg. benzodiazepines, barbiturates, antiemetics) and by recre ....This project seeks to provide fundamental new information about the means by which neurotransmitter receptors, which mediate fast synaptic neurotransmission, operate. This knowledge is important since the Cys-loop family of ligand gated ion channel receptors are responsible for a wide range of neuronal signalling and the control of both excitatory and inhibitory receptors. The Cys-loop receptors are modulated by both therapeutic drugs (eg. benzodiazepines, barbiturates, antiemetics) and by recreational drugs (eg. alcohol, nicotine). They are also targets for development of new therapeutic drugs, such as allosteric modulators of nAChR for memory enhancement, or modulating GlyR to relieve spasticity or chronic pain. The project will use a range of molecular advances made by this and other laboratories to clarify how neurotransmitters enable their receptors to activate and signal. This fundamental information is of major medical significance as defective synaptic transmission, caused by mutations in ligand gated ion channel receptors, gives rise to a number of neurological and psychiatric disease states. The ligand gated receptors are also major targets for therapeutic drugs and the information gained in this study may also provide insights into new ways in which drugs could be used to enhance or inhibit synaptic signalling.Read moreRead less
A Case-control Study Of Rotavirus Vaccine Effectiveness Against Gastroenteritis Hospitalisation Of Children In The NT

Funding Amount

Summary
Almost 1 out of 5 children in remote Aboriginal communities are hospitalised with diarrhoea caused by rotavirus. This study will evaluate the impact of rotavirus vaccination in preventing these hospitalisations. In addition to making sure that vaccination works and that those at highest risk are receiving the benefits, it will assess the indirect impact against other causes of diarrhoea providing, critical information relevant to the vaccine's broader introduction in developing country settings.
A Randomised Controlled Trial Of Caseload Midwifery Care

Funding Amount
$761,311.00
Summary
There is concern about the rising levels of caesarean section in Australia and some evidence that women may benefit from caseload midwifery care. This randomised control trial will determine whether caseload midwifery care can reduce interventions and is as safe as usual hospital maternity care. A Cochrane systematic review of midwifery led care versus routine care was designed to answer these questions.This will be the first randomised controlled trial to contribute to this review
Tracking The Impact Of Drug Regulatory Actions: Consumer Health Outcomes, Risk-benefit Issues And Policy Framework.
Funder

Funding Amount
$439,324.00
Summary
This study will explore what happens in the community when a medicine is withdrawn from the market or discredited due to safety concerns. It will examine the impacts of two recent cases of medicine withdrawal or serious long-term safety concern, on a large cohort of women with high utilisation rates who were monitored during the time the medicines were discredited. The study will be an important guide to future regulatory, media and provider responses when medicines are discredited.
