Summary
The course of non-cancer related disease is difficult to assess clinically making it hard for clinicians to accurately predict the end of life course of illness for patients. No matter what the end of life disease is, death will involve multi-system organ failure and changes in body composition. These changes, including fluid distribution, muscle mass and type and fat mass as well as measures of body mass index, basal metabolic rate and arm muscle circumference can be accurately followed with no ....The course of non-cancer related disease is difficult to assess clinically making it hard for clinicians to accurately predict the end of life course of illness for patients. No matter what the end of life disease is, death will involve multi-system organ failure and changes in body composition. These changes, including fluid distribution, muscle mass and type and fat mass as well as measures of body mass index, basal metabolic rate and arm muscle circumference can be accurately followed with non-invasive multi-frequency bio-impedance. This information will provide a basis to either confirm the clinical diagnosis or lead to recommendations for change.Read moreRead less

Summary
In this research the team will use advanced biotechnological techniques to study the distribution and virulence markers of an important emerging infectious disease, enterovirus 71 encephalitis, in the Asia-Pacific region. The knowledge and technical advances derived from this study will be shared with neighbouring countries in order to conduct sensitive surveillance for this infection throughout the region.

The knowledge and technical advances derived from this study will be shared with neighbouring countries in order to conduct sensitive surveillance for this infection throughout the region. The study's other major aim is to use cutting-edge biotechnological techniques to develop a genetically defined, live attenuated vaccine strain. Candidate vaccine strains will be tested for their effectiveness in both cell culture-based and animal models.Read moreRead less

Summary
As health care costs rise, governments increasingly will need objective evidence on the benefits and costs of health intervention options, whilst taking into account the need for greater health equity, transparency of decision making and stakeholder acceptability. This project will provide the health intelligence to guide such health priority setting in Australia, with a focus on prevention of non-communicable diseases, the implications for Indigenous Australians and the most efficient ways of i ....As health care costs rise, governments increasingly will need objective evidence on the benefits and costs of health intervention options, whilst taking into account the need for greater health equity, transparency of decision making and stakeholder acceptability. This project will provide the health intelligence to guide such health priority setting in Australia, with a focus on prevention of non-communicable diseases, the implications for Indigenous Australians and the most efficient ways of implementing priority interventions in primary care.Read moreRead less

Summary
Chronic heart failure is increasing in prevalence and is primarily a condition of ageing. Although chronic heart failure has worse outcomes than many cancers, patients are often denied the benefits of palliative care with its emphasis on symptom management, spirituality, emotional health and focus on family issues. This project seeks to assess the state of knowledge in Australia related to palliative care in chronic heart failure. Guidelines and care maps appropriate to Australian conditions wil ....Chronic heart failure is increasing in prevalence and is primarily a condition of ageing. Although chronic heart failure has worse outcomes than many cancers, patients are often denied the benefits of palliative care with its emphasis on symptom management, spirituality, emotional health and focus on family issues. This project seeks to assess the state of knowledge in Australia related to palliative care in chronic heart failure. Guidelines and care maps appropriate to Australian conditions will be developed and their usefulness assessed in improving care of patients and their families.Read moreRead less
Approaches to combat AIDS and its causative agent, the human immunodeficiency virus HIV-1, have thus far proved ineffective. The proposed research program intends to investigate the nuclear import of two HIV-1 proteins which have central roles in HIV infection. We will apply our expertise in the area of the regulation of nuclear import of viral proteins, and build on our observations with respect to these proteins to attempt to establish the mechanistic basis of their nuclear import, and how thi ....Approaches to combat AIDS and its causative agent, the human immunodeficiency virus HIV-1, have thus far proved ineffective. The proposed research program intends to investigate the nuclear import of two HIV-1 proteins which have central roles in HIV infection. We will apply our expertise in the area of the regulation of nuclear import of viral proteins, and build on our observations with respect to these proteins to attempt to establish the mechanistic basis of their nuclear import, and how this differs from the conventional nuclear import pathways used by normal cellular proteins. We already have evidence that nuclear import of HIV-Tat is regulated in novel fashion by cellular factors, and intend, through determining its mechanistic basis, to be able to form the basis of a strategy to block this import pathway specifically, and thereby inhibit HIV replication. This may form the basis in the future of a new pharmaceutical approach to combat HIV-AIDS.Read moreRead less
HIV infection of CD4+ lymphocytes leads to a high rate of reproduction of new virus. However, in the brain, HIV infection of the astrocytes does not yield high levels of new virus. HIV is genetically active in these astrocytes, producing high levels of the messenger molecules, the so-called mRNA, that code for the proteins required for a new virus particle. We have determined that these HIV mRNAs are specifically prevented from translating into protein. The mechanisms controlling protein transla ....HIV infection of CD4+ lymphocytes leads to a high rate of reproduction of new virus. However, in the brain, HIV infection of the astrocytes does not yield high levels of new virus. HIV is genetically active in these astrocytes, producing high levels of the messenger molecules, the so-called mRNA, that code for the proteins required for a new virus particle. We have determined that these HIV mRNAs are specifically prevented from translating into protein. The mechanisms controlling protein translation from RNA are relatively poorly understood compared with the other control points of cellular gene expression, such as the synthesis of mRNA. This project examines how astrocytes rapidly detect the presence of HIV mRNA and alter their translation machinery to halt the expression of HIV protein. This host defence mechanism involves two key components; the cellular component that identifies and responds to the viral mRNA, and the structural features of the HIV mRNA that enable the cell to detect its viral origin. We will study how translation of HIV proteins requires both HIV and cellular factors. We will determine the impact of both viral RNA elements and viral RNA binding proteins on the translation of viral and cellular proteins. The contribution of the type-1 interferons that are produced in response to viral infection will be studied for their role in augmenting the inhibition of HIV protein translation. Since HIV infected astrocytes significantly contribute to the onset of AIDS dementia, we will sees a strategy to lock HIV into a dormant state in the brain and thereby prevent the neurodegenerative disease associated with HIV. We will use the anti-viral mechanism blocking HIV protein translation in astrocytes to protect other cell populations, such as the CD4+ lymphocytes, from HIV infection. These studies will also give insights into the general mechanisms for translational control of gene expression in human cells.Read moreRead less
