Summary
NHMRC 209113 LAY DESCRIPTION Ischaemia reperfusion injury occurs in skeletal muscle when the blood-oxygen supply is cut off (ischaemia) and later restored (reperfusion). If the duration of ischaemia is short some of the muscle survives. However, when blood flow and oxygen are restored the muscle is subjected to more injury, which is thought to be caused by oxygen and-or white blood cells. This type of injury occurs in muscle which has been crushed, limbs that have been broken or traumatized, in ....NHMRC 209113 LAY DESCRIPTION Ischaemia reperfusion injury occurs in skeletal muscle when the blood-oxygen supply is cut off (ischaemia) and later restored (reperfusion). If the duration of ischaemia is short some of the muscle survives. However, when blood flow and oxygen are restored the muscle is subjected to more injury, which is thought to be caused by oxygen and-or white blood cells. This type of injury occurs in muscle which has been crushed, limbs that have been broken or traumatized, in replantation of amputated parts, in transplantation, after some surgical procedures and after microsurgical transfer of muscle. Once established there is no effective treatment. Our experiments show that a particular cell, the mast cell, and a particular molecule, nitric oxide, are involved in causing ischaemia reperfusion injury. However, the extent of their involvement is unknown. In this proposal we will investigate the effect of replacing mast cells into muscles, in a unique variety of mice which normally don t contain mast cells and are resistant to ischaemia reperfusion injury. In one group of mice we will put back normal mast cells and in a second group of mice we will put back mast cells that cannot produce the nitric oxide molecule. These experiments will determine, unambiguously, the extent of involvement of mast cells and mast cell-derived nitric oxide. In the second part of this proposal will carry out a time course study, using pharmacologically induced mast cell degranulation, to determine when the mast cells become injurious to skeletal muscle. These experiments will identify the period during which mast cell behaviour can be modulated in order to protect the muscle from ischaemia reperfusion injury. Determination of the role of mast cells, and an understanding of the timing during which they become injurious would provide a logical basis for optimizing drug therapy in clinical applications of these findings.Read moreRead less

Summary
This project aims to investigate the progressive change in cerebrospinal fluid dynamics, axonal damage and tissue mechanical properties during the development and treatment of hydrocephalus in-vivo. Results from this study is important to elucidate the mechanisms of hydrocephalus and to improve treatment and diagnosis of hydrocephalus.

Summary
Research evidence plays a crucial role in improving clinical care. However the main forms of evidence and the tools that facilitate evidence use - namely randomised controlled trials (RCT) and structured systematic reviews of existing research - have had limited application in surgery for a variety of reasons. This project aims to promote the use of research evidence in surgical decision making by developing tools tailored to the predominance of non-RCTs in surgery and surgeons' information need ....Research evidence plays a crucial role in improving clinical care.

Molecular Mechanisms Of Tumour-associated Seizures

Summary
Seizures commonly develop in patients with brain tumours. Despite tumour resection, patients continue to experience seizures. Furthermore, patients can often be resistant to treatment with anti-epilepsy medications adding further burden to patient suffering, decreasing quality of life and overall survival. The cause is unknown and we propose identifiable causes are involved. This will provide effective targets for the development of medications for the treatment of these seizures.
A Novel Tumour-targeting Nanoliposome Drug Delivery System For The Treatment Of Malignant Gliomas

Funding Amount
$445,097.00
Summary
Most patients with malignant brain tumours die within a year after diagnosis due to the difficulty in effectively delivering drugs to the tumour cells. We aim to develop a safe and novel drug delivery system to effectively deliver anticancer drugs and novel anticancer agents to brain tumour cells that remain in normal brain after surgery. The success of this project will bring us a step forward in our efforts to significantly improve the survival rate and quality of life of such patients.

Summary
Strokes are one of the biggest killers of Australians and are becoming increasingly so every year. Bleeding from the brain involves extremely delicate and dangerous medical treatments. The development of NanoNautilus [TM]---a remote-controlled steerable microcatheterusing world-first miniaturization technology---will revolutionise current practises and greatly reduce the current risk with medical intervention.
