Summary
Children’s burns are physically and psychologically debilitating and are a huge burden for the children themselves, their families and the Australian health care system. My work will determine exactly what conditions are required to cause burns so that we can act to prevent them. I will also develop more effective first aid treatment and new treatments to improve burn wound healing.

Summary
Scarring is the inevitable outcome of wound repair and can cover a spectrum of conditions, from normal fine lines to unsightly, restrictive and deforming scars. Each year in the world over 100 million patients acquire scars, primarily from surgical procedures. Many of these scars cause considerable problems. Over 4 million burn scars occur every year, 70% of them in children. Poor wound healing is a major clinical problem and can result in loss of movement and deformity.

Each year in the world over 100 million patients acquire scars, primarily from surgical procedures. Many of these scars cause considerable problems. Over 4 million burn scars occur every year, 70% of them in children. Poor wound healing is a major clinical problem and can result in loss of movement and deformity. These are especially important considerations for children, where their growth places extra demands on healing wounds and grafts, necessitating regular surgical adjustment. Scarring is an area of largely unmet medical need and development of new treatment strategies would have significant impact on public health. Changes in cell adhesion, shape and movement are important processes in wound repair. A framework of filaments, much like guy-ropes that support a tent, help coordinate these events. Remodelling of these filaments, shortening or extending them and making new connections, allows cells to change shape and respond to stimuli. This is a crucial event in repairing wounds and the proteins that perform this are fundamentally important to wound repair. We have discovered a protein in skin, known as Flightless, that is involved in this filament remodelling process. The goal of this project is to determine what Flightless does in wound repair. By changing the amount of this protein and comparing its effect in non-scarring and scarring animal wound healing models we can gain insight into its role in wound healing and scar formation in humans. The development of new animal models in this research and the discovery of the role of Flightless in wound repair will provide exciting new opportunities to improve wound repair and reduce scarring, with significant impact on public health.Read moreRead less
This project aims to improve the acute treatment of children with burn injuries through developing more effective and novel treatments and understanding the conditions required for burn injuries to occur.
Development Of Monoclonal Antibody Therapy For Treating Wounds

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
Chronic wounds affect more than 9 million people worldwide and demand for wound care is increasing. The annual cost to healthcare systems in the US and Australia in treating such wounds is US$25 billion and AU$3 billion, respectively, and there is urgent need for more effective approaches.

Summary
Millions of people worldwide receive burn injuries every year and last year the Royal Children's Hospital in Brisbane alone treated more than 500 children with new burn injuries. Many of these children with burn injuries will heal burn wounds with unsightly scars and impaired skin function. Cooling burns as first aid has been used since ancient time and is proved to be the most effective way to reduce skin temperature, lessen pain, minimize the depth of injury, and ultimately improve wound heali ....Millions of people worldwide receive burn injuries every year and last year the Royal Children's Hospital in Brisbane alone treated more than 500 children with new burn injuries. Many of these children with burn injuries will heal burn wounds with unsightly scars and impaired skin function. Cooling burns as first aid has been used since ancient time and is proved to be the most effective way to reduce skin temperature, lessen pain, minimize the depth of injury, and ultimately improve wound healing outcome. However, despite the evidence that cooling burns using ice water <4 C may be beneficial to burns, current first aid recommend to only use cold water 8-25 C and the use of ice-ice water is strongly discouraged for fear of the potential to cause hypothermia and deepen the existing burn injury. In this application we will examine the effect of ice-ice water 2 C on wound healing outcome compared to 15 C water as first aid, in an in vivo model. The wound healing will be clinically assessed by experienced clinicians weekly for six weeks, and then will also be assessed histologically and mechanically at week six. We will also determine the optimal cooling temperature and duration for injured tissue in burn wounds to recover and the conduction of cold through skin. With the coming new knowledge we wish to design an optimal cooling burn treatment which will maximize the beneficial of cooling to the burns but avoid adverse effect of excessive cooling. The success of this project will advance our knowledge on first aid treatment or burn cooling treatment and also wound healing process. It will enable us to offer better first aid treatment which may lead to wound healing with less scars, otherwise can not achieved by other current available treatments. The better healing of burn wounds will significantly improve burn patients' lives, particularly children with burn injuries. It will also release the burden on much needed health funds.Read moreRead less
This project will develop a smart bone healing gel to bridge fragments of bone defects leading to stem cell recruitment, reduced inflammation, and blood supply for fracture healing. The design of the smart bone healing gel is based on the structures and properties of functional tissue healing hematoma in wound healing.

Summary
The healing of wounds is a complex process involving a number of stages, including coagulation, inflammation, remodelling and finally development of full strength skin. Impaired wound healing and-or skin ulcers occur in patients with peripheral arterial occlusive disease, deep vein thrombosis, diabetes, pressure sores and burns. Despite intense investigation, the precise mechanisms associated with impaired healing are poorly understood.

Impaired wound healing and-or skin ulcers occur in patients with peripheral arterial occlusive disease, deep vein thrombosis, diabetes, pressure sores and burns. Despite intense investigation, the precise mechanisms associated with impaired healing are poorly understood. APC is a serine protease that plays a central role in physiological anticoagulation. APC potently activates gelatinase A, an enzyme that plays a prominent role during the remodelling phase of wound healing and angiogenesis. Our preliminary experiments provide very strong evidence that APC accelerates wound healing using both cultured cells and a rat skin wounding model. There are three aims to this study. The first will use cell culture techniques to investigate the mechanisms of action of APC during wound healing. Secondly, we will expand our pilot studies on the effect of APC as a promoter of wound healing in vivo. These studies will examine the exact dosing and timing regime for APC, using a rat wound healing model. In addition, we will test the effect of APC on slow healing wounds, present in diabetic rats. Thirdly, we will determine whether APC is quantitatively or functionally deficient in human wound fluid derived from slow-healing wounds compared to wounds that heal normally. This is the first time that APC has been implicated in wound healing. It is envisaged that this work will ultimately lead to a novel topical treatment of APC to accelerate slow-healing wounds.Read moreRead less
