Summary
There are currently no effective treatments for Alzheimer's disease. In this application we will develop a novel class of compound to assess their potential as AD therapeutics. These compounds will be tested in vitro and in vivo models of Alzheimer's disease. The successful conclusion of the work described here would provide new leads suitable for further development as therapeutics for Alzheimer's disease.
Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to ....Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to improve radiotherapy treatments in patients with small lesions with sizes of up to a few centimetres. This will lead to an improved outcome for some cancer patients.Read moreRead less
Antiviral compounds to inhibit the replicase of hepatitis C virus. Hepatitis C virus is a major public health problem. There are currently 200,000 infected individuals in Australia and 16,000 new infections every year. There is no specific treatment and current therapy treats a small percentage of patients only, which consists of interferon-alpha and ribavirin. This results in side effects and only a 50% cure rate. This study's outcomes are expected to lead to greater access to treatment and imp ....Antiviral compounds to inhibit the replicase of hepatitis C virus. Hepatitis C virus is a major public health problem. There are currently 200,000 infected individuals in Australia and 16,000 new infections every year. There is no specific treatment and current therapy treats a small percentage of patients only, which consists of interferon-alpha and ribavirin. This results in side effects and only a 50% cure rate. This study's outcomes are expected to lead to greater access to treatment and improved therapy resulting in higher cure rates and in a dramatic reduction in the cost of treating patients. A novel therapy will provide considerable benefits for the national biotechnology industry.Read moreRead less
Development of therapeutic agents that target carbonic anhydrase enzymes. This research will discover new chemical entities (compounds) that may lead to therapies for the treatment of cancer, glaucoma and malaria. The research underpins a mechanism to add value to our compounds before partnering with industry to transform the discoveries made here to deliverable therapies that could benefit the health of millions, thus offering a potentially high value contribution to the Australian economy.

The research underpins a mechanism to add value to our compounds before partnering with industry to transform the discoveries made here to deliverable therapies that could benefit the health of millions, thus offering a potentially high value contribution to the Australian economy. The experience and commitment of the multi-disciplinary network of researchers offers exceptional training and employment opportunities for tomorrow's scientists in techniques for discovery and characterisation of novel chemicals, and their interaction with disease targets.Read moreRead less
Mammalian chitinases and gene therapy: new weapons to combat fungal and insect attack in mammals. Plants combat fungal and insect attack by producing chitin degrading enzymes. Related, chitinolytic enzymes have been identified in mammals, but their functions are unclear. We found that chitinases from human macrophages inhibited fungal growth. We hypothesise that, like plants, mammalian chitinases are produced to fight chitin containing pathogens. We will transform cells with a chitotriosidase ge ....Mammalian chitinases and gene therapy: new weapons to combat fungal and insect attack in mammals. Plants combat fungal and insect attack by producing chitin degrading enzymes. Related, chitinolytic enzymes have been identified in mammals, but their functions are unclear. We found that chitinases from human macrophages inhibited fungal growth. We hypothesise that, like plants, mammalian chitinases are produced to fight chitin containing pathogens. We will transform cells with a chitotriosidase gene and encapsulate them, creating bioreactors secreting chitinases. Therapeutic effects will be tested by grafting bioreactors to mice inoculated with Aspergillus. The research is a new approach to fighting chitin containing pathogens, with potential applications from parasite infestations in livestock to fungal infections in humans.Read moreRead less
Development of Acid Degradable Polymeric Nanoparticles for Intracellular and Tumour Site Selective Delivery of Drugs. There is an enormous need to develop effective anticancer drug delivery systems to reduce the social and economic impact of cancer. One of the most critical problems in tumour treatment is the lack of selective toxicity of anticancer drugs against tumour tissues. Our multidisciplinary team will aim to develop a novel polymer based system for tumour site-selective delivery of anti ....Development of Acid Degradable Polymeric Nanoparticles for Intracellular and Tumour Site Selective Delivery of Drugs. There is an enormous need to develop effective anticancer drug delivery systems to reduce the social and economic impact of cancer. One of the most critical problems in tumour treatment is the lack of selective toxicity of anticancer drugs against tumour tissues. Our multidisciplinary team will aim to develop a novel polymer based system for tumour site-selective delivery of anticancer drugs. Development of such advanced drug delivery systems will significantly enhance Australia`s power in biotechnology. Development and/or formation of strategies to improve the health quality of Australians, is an important anticipated outcome of this innovative project.Read moreRead less
Auditory and Vestibular Ringing--Detection and theraputic interventions. Tinnitus effects up to 30% of the elderly population. To date no single suppression modality has been successful across all tinnitus sufferers. This study will apply an aural, low level, modulated, fractal suppression strategy designed to induce a "natural" olivary efferent response capable of suppressing/reducing tinnitus.

This study will apply an aural, low level, modulated, fractal suppression strategy designed to induce a "natural" olivary efferent response capable of suppressing/reducing tinnitus.
Balance disorders e.g. Meniere's Disease and nausea (seasickness) are unwanted outcomes of vestibular dysfunction/hypersensitivity. This study will apply a low level, low frequency, modulated, acoustic pressure wave designed to induce a ?natural? olivary efferent response and an end organ endolymph/perilymph balance shift. It is postulated these stimuli will reduce the effects of vestibular dysfunction/hypersensitivity.

Topical peptide delivery for cosmetic and therapeutic benefits. Milk is a major Australian agricultural commodity and is now used in a number of topical products for the management of various skin conditions including chafing in babies, eczema and ageing skin. Hence, this work hopes to contribute to promoting and maintaining good health of Australians.
In addition, there is considerable research being conducted on peptide development for a range of diseases and there may be a possibility of ....Topical peptide delivery for cosmetic and therapeutic benefits. Milk is a major Australian agricultural commodity and is now used in a number of topical products for the management of various skin conditions including chafing in babies, eczema and ageing skin. Hence, this work hopes to contribute to promoting and maintaining good health of Australians.
In addition, there is considerable research being conducted on peptide development for a range of diseases and there may be a possibility of delivering these by the skin.
This work, in seeking to understand some of the fundamental determinants governing how exogenously applied peptides distribute in the skin, is also contributing to the development of Australian pharmaceutical and cosmetic industries.Read moreRead less
