Design of Neonatal Seizure Diagnosis Methods Using Time-Frequency Signal Processing Techniques. Seizures occur in approximately 0.5% of all newborns. They are often the only indicator of an early dysfunction in central nervous system (CNS). Their occurrence raises concerns about the underlying cause, its effect on the brain, and the appropriate treatment. Newborn seizures are mostly sub-clinical and only detected through the Electroencephalogram. For an efficient diagnosis, seizure classificatio ....Design of Neonatal Seizure Diagnosis Methods Using Time-Frequency Signal Processing Techniques. Seizures occur in approximately 0.5% of all newborns. They are often the only indicator of an early dysfunction in central nervous system (CNS). Their occurrence raises concerns about the underlying cause, its effect on the brain, and the appropriate treatment. Newborn seizures are mostly sub-clinical and only detected through the Electroencephalogram. For an efficient diagnosis, seizure classification systems were proposed based on visual observations. This project proposes developing a novel approach to automate the classification process using time-frequency (TF) signal processing techniques based on the multi-channel characteristics of the seizure; namely: A) TF signature B) origin, and C) propagation behaviour.Read moreRead less
Molecular and antibody analysis of cytomegalovirus (CMV) infection of fetal and placental cells. CMV is a beta herpesvirus with many unknown molecular mechanisms associated with cellular infection. The virus infects placental cells in vivo, although pathogenesis of viral damage to these cells has been extremely difficult to study in vitro. We have commenced a study to i) demonstrate the molecular accompaniments of infection of placental cells in vitro, ii) determine the genotypic characteristics ....Molecular and antibody analysis of cytomegalovirus (CMV) infection of fetal and placental cells. CMV is a beta herpesvirus with many unknown molecular mechanisms associated with cellular infection. The virus infects placental cells in vivo, although pathogenesis of viral damage to these cells has been extremely difficult to study in vitro. We have commenced a study to i) demonstrate the molecular accompaniments of infection of placental cells in vitro, ii) determine the genotypic characteristics of congenital CMV infections, in collaboration with Abbott Diagnostics, and iii) produce an in vivo model of CMV infection to demonstrate the pathogenesis of cellular injury. The combination of molecular expertise at UNSW with monoclonal antibody expertise from Abbott Diagnostics mean this project is unique worldwide.Read moreRead less
The HPA-axis as a marker for disruptive behaviour disorder subtypes in toddlers. Emerging neurobiological models of antisocial behaviour emphasise the role of the hypothalamic-pituitary-adrenal (HPA) axis in the onset of disruptive behaviour disorders (DBDs). Given the broad consensus that antisocial trajectories originate in the toddler years, this project will use cortisol measures of HPA-axis activity to identify the mechanisms through which developmental factors interact with parenting and ....The HPA-axis as a marker for disruptive behaviour disorder subtypes in toddlers. Emerging neurobiological models of antisocial behaviour emphasise the role of the hypothalamic-pituitary-adrenal (HPA) axis in the onset of disruptive behaviour disorders (DBDs). Given the broad consensus that antisocial trajectories originate in the toddler years, this project will use cortisol measures of HPA-axis activity to identify the mechanisms through which developmental factors interact with parenting and family environment to shape persistent DBDs; this will be achieved by following toddlers with severe DBDs across a controlled trial of a parenting intervention.Read moreRead less
