Summary
While the mechanisms of local anaesthesia are comparatively well known, the mechanisms whereby anaesthetics impair consciousness remain unresolved. This lack of understanding has implications in our ability to monitor the level of anaesthesia while anaesthetic consumption and side effects are minimized. Despite this a number of devices have been developed that attempt to monitor the depth of anaesthesia by quantifying the brains electrical activity. All monitors analyse the activity using a set ....While the mechanisms of local anaesthesia are comparatively well known, the mechanisms whereby anaesthetics impair consciousness remain unresolved. This lack of understanding has implications in our ability to monitor the level of anaesthesia while anaesthetic consumption and side effects are minimized. Despite this a number of devices have been developed that attempt to monitor the depth of anaesthesia by quantifying the brains electrical activity. All monitors analyse the activity using a set of criteria that have been developed by trial and error. The research of Dr David Liley and his team, at Swinburne University of Technology, has resulted in a detailed understanding of the physiological mechanisms that generate brain electrical activity. The outcome is a practical means to carry out a System Based Analysis of Brain Electrical Response (SABER). In 2004, Dr Liley began working with Cortical Dynamics, a company involved in the commercialisation of medical devices. This collaboration incorporated the SABER system into a new prototype device called the Brain Anaesthesia Response (BAR) monitor. In 2004 Dr Liley and Associate Professor Kate Leslie collaborated in a trial, at the Royal Melbourne Hospital to test the sensitivity of the SABER system in quantifying the effect that various levels of nitrous oxide have on measures of anaesthetic depth. The Australian and New Zealand College of Anaesthetists supported this study. Initial results obtained with sevoflurane and 3 levels of nitrous oxide showed the ability to differentiate between conscious and unconscious states of patients based on two physiological characterizations of higher brain dynamic state. The next step requires commercial product validation (ie scale up) and further clinical efficacy in testing beta stage depth of anaesthesia BAR units. Completion of this will help the technology move away from a low volume prototype system into a commercially applicable device.Read moreRead less

Funding Amount
$573,354.00
Summary
Chronic wounds, diabetic ulcers, injuries in response to trauma, burns and scalds form a medical need which will only expand as the population ages and the diabetic epidemic grows. In our studies, we have shown that Flightless I (Flii), an actin-remodelling protein, is a negative regulator of wound healing. We are developing monoclonal antibodies as a new therapy for reducing Flii levels in wounds which leads to improved wound repair outcomes.

Summary
Primary malignant brain tumors are amongst the most lethal forms of human cancers with median survival for these patients being only around 1 year. In spite of the advent of new targeted therapies for some cancers the prognosis for these patients remains dismal. Worldwide, more than 95% of all people who contract the disease will die of it. This is because there are no effective therapies and all current treatments are only palliative, seeking to lesson the distressing suffering associated with ....Primary malignant brain tumors are amongst the most lethal forms of human cancers with median survival for these patients being only around 1 year. In spite of the advent of new targeted therapies for some cancers the prognosis for these patients remains dismal. Worldwide, more than 95% of all people who contract the disease will die of it. This is because there are no effective therapies and all current treatments are only palliative, seeking to lesson the distressing suffering associated with disease progression. Nearly all therapies that have shown some efficacy in treating cancer, such as chemotherapy and radiation have a mode of action whereby they attempt to kill cancer cells by inflicting enough damage to the cancer cells that they induce them to commit cell suicide, a process called apoptosis. Unfortunately, cancer cells can become resistant to these therapies by activating the cells' own signaling pathways that normally block apoptosis. One of the key pathways that has been implicated in resistance to apoptosis in human cancers is the PI3K-Akt pathway. This pathway is overactivated in many advanced human tumors, particularly in glioblastoma. We have discovered a compound, Se015, which can effecitively block this pathway in brain cancer cells and is able to dramatically improve the effectiveness of both chemotherapy and radiation in killing these cells. We have confirmed the efectiveness of Se015 in preliminary animal models of brain cancer, where we have shown that Se015 demonstrated no noticeable toxicity and was active when taken orally. We now need to explore further the molecular mode of action of Se015, as well as complete our animal studies with the eventual aim of initiating a small trial of Se015 in glioblastoma patients in the forseeable future.Read moreRead less
Neuropathic Pain Drugs Based On The Endogenous Opioid Peptide Endomorphin 1.

Funding Amount
$209,470.00
Summary
We have developed a new pain drug based on the natural pain killing opioid peptide, Endomorhin 1. The new drug exhibits activity similar to morphine and gabapentin against neuropathic pain in animals but seems to act through a different mechanism. We will complete our preclinical investigation of this compound by assessing its side effect profile and tolerence inducing properties in animals. We will also continue our development of an orally active analogue of this important peptide.
Newborn babies are at risk of becoming short of oxygen during delivery and sustaining brain damage. Seizures may cause further damage to the brain because they release damaging chemicals or make extra energy demands on the brain that cannot be met. To detect seizures, it is necessary to measure the EEG, the tiny electrical signals from the brain. We are proposing to automatically detect and count seizures, building upon 8 years of fundamental EEG signal processing research work we have undertake ....Newborn babies are at risk of becoming short of oxygen during delivery and sustaining brain damage.

Summary
PET-CT imaging is a vital tool in the diagnosis and management of patients with brain disorders including dementia, epilepsy and cancer. However images are often distorted by patient motion, particularly in demented and paediatric patients. The CI has recently developed a motion tracking and correction method to derive images nearly free of motion effects. This aim of this project is to evaluate its impact on image quality in a variety of patients referred for PET- CT brain investigations.
