Summary
This study investigates a new therapeutic action recently discovered for flecainide, an antiarrhythmic agent that we find to completely prevent and inherited form of stress-induced arrhythmias called CPVT. The findings will provide the first detailed mechanistic understanding of an antiarrhythmic drug, findings that will also give a new direction for drug design to control common arrhythmias such as occur in diseases such as coronary artery disease.
Functional Brain Age Measurement In Children And Adolescents

Summary
An important aspect of medicine is measuring the function of the human body. It is often advantageous to convert complex functional measures into simpler, intuitive measures such as 'age'. We can compare functional age to chronological age to diagnose disease. In this project, we will build an estimate of 'brain age' in children and adolescents using recordings of the electrical activity of the brain. We will test this 'brain age' as a diagnostic tool in several neurological disorders.
Novel Mechanism Underlying The Behavioural And Neurocognitive Deficits In Children With Sleep Disorders.

Summary
About one third of Australian children have a sleep disorder. Behavioural or academic problems are common in these children, however the link between sleep and daytime problems is still not clear. New research suggests the pattern of brain activity during deep sleep may provide some answers. This study will explore the link between brain activity during deep sleep and daytime functioning in children with sleep disorders, providing valuable information for treatment.
Novel Therapy For Enhancing Organ Maturation In Pre-term Babies

Summary
This project is developing a factor to enhance organ maturation and repair that may provide a new therapy for premature babies and fetuses with birth defects. This exciting new finding allows for the development of treatments of underdeveloped organs, in particular the lungs of premature and growth restricted babies. We are also trialing this factor in unborn babies with defects to the kidneys and lungs of which there is currently no cure.
Developmental Changes In Cerebral Oxygenation After Term And Preterm Birth

Summary
Approximately 10% of all births are preterm and the numbers of infants surviving are increasing. We have previously found that infants born preterm have lower blood pressure over the first 6 months after term equivalent age than infants born at term. We will use new technology to examine how preterm birth affects brain oxygenation and how this is altered with gestational age, sleep states and sleeping position, to provide insights into their increased risk for SIDS.
Development Of An In Vivo Pharmacokinetic-pharmacodynamic Model For Evaluation Of Antimalarial Drug Therapy Combinations

Summary
The World Health Organization currently estimates that there are 300-500 million cases of malaria annually, with 1.5-2.7 million deaths. These are staggering data, given that almost 20 antimalarial drugs are now in regular clinical use. Multi-drug resistance is present in most tropical countries where malaria is endemic and there has been a rapid escalation in cases of malaria in developed countries over recent decades (imported by travellers). Clearly, there is a need to ensure that current and ....The World Health Organization currently estimates that there are 300-500 million cases of malaria annually, with 1.5-2.7 million deaths. These are staggering data, given that almost 20 antimalarial drugs are now in regular clinical use. Multi-drug resistance is present in most tropical countries where malaria is endemic and there has been a rapid escalation in cases of malaria in developed countries over recent decades (imported by travellers). Clearly, there is a need to ensure that current and new treatment and prevention strategies are rational and effective. This project is based on the premise that improvements can be made in the in vitro testing process of antimalarial drugs. The experiments will be conducted using mice and a form of malaria that is specific to mice but closely resembles human malaria. In the first stage, the relationship between the amount of a new antimalarial drug (dihydroartemisinin) in the body and the effectiveness of the dose will be tested. These experiments will be repeated using conventional antimalarial drugs such as mefloquine. Information from these studies will subsequently be used to evaluate combinations of antimalarials. The results will be used as the basis of extensive, collaborative clinical studies in South-East Asia that are beyond the scope of this project. The methods used for this research will be important for future testing of new antimalarial drugs or combinations of drugs for the treatment and prophylaxis of malaria.Read moreRead less
