Summary
Chronic liver diseases, particularly those caused by autoimmune disease, alcohol and Hepatitis B and C virus infection, are major causes of morbidity and mortality in our community. They are characterised by progressive scarring of the liver which finally leads to liver failure and the need in many cases for organ transplantation. Each year 15,000 Australians become infected, probably for life, with hepatitis C virus.

They are characterised by progressive scarring of the liver which finally leads to liver failure and the need in many cases for organ transplantation. Each year 15,000 Australians become infected, probably for life, with hepatitis C virus. Unless more effective treatments are developed approximately 20% of these infections will progress to liver failure or liver cancer within 30 years. Diabetes afflicts 150 million people, and 90% have Type 2 diabetes. We request funding of our research on a family of enzymes highly prospective as targets for novel therapies for these diseases. We are internationally recognised experts on this enzyme family and on liver disease. The prototype member of this enzyme family, dipeptidyl peptidase (DP) IV, is being targeted by novel drugs that are in phase III clinical trials for Type 2 diabetes. Family member fibroblast activation protein (FAP) is targeted by novel anti-cancer drugs We were first to clone and lodge patent applications for two new enzymes of this family, DP8 and DP9. Our research proposal would lead to determination of whether FAP, DP8 and-or DP9 are valuable targets for novel liver disease therapeutics and facilitate generating the development of such therapeutics by a more thorough understanding of the activities and roles of these enzymes Completion of this project will greatly increase our understanding of these enzymes and their roles in chronic liver injury. This work can potentially lead to the development of specific inhibitors of enzyme function designed to relieve liver damage.Read moreRead less
Production Of Nasal Filters: Enhanced Prophylactic Protection From Aerosol Exposure

Summary
Influenza is a highly contagious disease that is transmitted via infective secretions containing the virus. An infected person produces tiny droplets of these secretions when coughing, sneezing, and talking, and the droplets are disseminated into the air where they are subsequently inhaled by others. A common way of preventing such transmission is to wear a mask to prevent droplet inhalation. While such masks may greatly reduce exposure, they do not eliminate it, as some viruses can pass around ....Influenza is a highly contagious disease that is transmitted via infective secretions containing the virus. An infected person produces tiny droplets of these secretions when coughing, sneezing, and talking, and the droplets are disseminated into the air where they are subsequently inhaled by others. A common way of preventing such transmission is to wear a mask to prevent droplet inhalation. While such masks may greatly reduce exposure, they do not eliminate it, as some viruses can pass around the edges of masks, particularly if it fits poorly, and also a small percentage can pass through the filter material. While influenza is usually not a major health problem in the general community, the emergence of a more hazardous strain will place an additional burden on health care and other facilities, and requires the development and optimization of measures to minimize virus spread and protect those who are exposed. The aim of this project is to build small filters that can be worn in the nose to provide additional filtration of inhaled air. These filters would be worn in combination with a mask in high exposure circumstances, such as by health care workers when treating infected patients or could be used when a mask was not normally worn to provide effective and discreet protection, such as in crowded public places. Developing such filters builds on our experience of making small samplers worn in the nose to measure allergen exposure. This experience is combined with advanced filter materials developed by leading US researchers that permit the efficient filtration of particles as small as viruses. This project will be conducted in collaboration with a leading Australian design group, and we will design and evaluate such filters for their ability to capture virus and thus protect the wearer. The filters should provide an intuitive, effective and inexpensive method to be used in combination with other hygiene measures to increase personal protection from acquiring highly transmissible respiratory diseases, particularly influenza. We expect to have prototypes of the filters available in 6 months so that production can commence.Read moreRead less
