Communication difficulties for older persons with limited English language proficiency and dementia provide a particular challenge in terms of meeting care needs effectively in residential settings. The current project will compare older Greek and Italian background persons with dementia who are residing in either mainstream or ethno-specific residential care facilities in Melbourne. The study will extend our pilot research, which focused on language use, and will also measure a number of factors that may influence the rate of communication, including prescribed psychiatric medication, language proficiency, cognitive impairment and behavioural-psychiatric symptoms. Additionally, the project will compare factors that may differ between the facility types, to provide further understanding of services offered. Furthermore, measures of satisfaction with the facility and quality of life will be included to provide an indication of the clinical significance of residing in a mainstream or ethno-specific aged care facility. The expected outcome of the study is to provide additional data in a very under researched and increasingly important field, to inform policy and practice, with the aim of improving the quality of life for older persons from diverse backgrounds in residential care.Read moreRead less

Summary
Virus-like particles (VLPs) provoke strong immune responses in the body. We have developed a novel VLP system that allows the production of VLPs containing foreign vaccine antigens of much larger size than previously possible, and have shown that these VLPs provoke strong immune responses in mice without the use of adjuvants.

We have developed a novel VLP system that allows the production of VLPs containing foreign vaccine antigens of much larger size than previously possible, and have shown that these VLPs provoke strong immune responses in mice without the use of adjuvants. The capacity of these VLPs is large enough to accommodate the most important vaccine antigen of influenza, the haemagglutinin (HA) molecule. We will test whether VLPs can be produced containing each of the three most important HA types _ H1 and H3 that are currently circulating in man, and H5 (avian) that is considered a pandemic threat. VLPs will be tested for their ability to induce neutralizing antibody and cellular immune responses in mice, and for their ability to protect ferrets from influenza infection. If successful, the HA-VLP system would provide a method for the rapid production of new influenza vaccines using large-scale fermentation technology as for hepatitis B and many other vaccines, rather than eggs or cell culture as used for current influenza vaccines.Read moreRead less

The virulent nature of these infections, and the fact that there is no pre-existing immunity to these viruses in the human population has raised the concern that these viruses may emerge to cause the next influenza pandemic. Vaccination is our most effective way of protecting against influenza infection, however there are no commercially available avian influenza vaccines available. Moreover, recent evidence suggests current vaccines strategies may be less than effective. This proposal aims to evaluate the efficacy of a novel vaccine strategy that promotes immune protection against a potential pandemic influenza strain.Read moreRead less

Mouse and human multipotent embryonic stem (ES) cells and fetal mouse panceas and adult pancreas duct cells will be used as sources of progenitor B cells. Comparative studies will provide a more complete picture of human B-cell ontogeny. Culture systems developed for ES cells-embryoid bodies (EB) - EB-derived cells, fetal pancreas and adult pancreas duct cells, will be employed to screen for and identify novel growth-differentiation factors and to optimise parameters for creating B cells in vitro or (re) generating B cells in vivo. Genetic constructs allowing regulated expression of fluorescently-tagged marker genes and growth-transcription factors will be introduced into cultured cells or transgenic mice to enable progenitor B cells to be tracked and isolated. Progenitor B cells will be typed with panels of known novel markers molecules at the gene and protein level, and gene expression profiles of tissue yielding B cells will be analysed across time to reveal further candidate markers. Molecules and methods effective in mouse systems will be applied to human ES cell-derived or pancreatic duct cells. The capacity to progenitor cells or insulin-secreting cells to ameliorate diabetes when transplanted into the testis, under the kidney capsule or into the pancreas of mouse models would represent proof-of-concept. Functional B cells derived from human ERS cells or pancreas duct cells, or growth factors that regenerate B cells in vivo, could together with appropriate immunotherapy restore B-cell function in people with type 1 diabetes.Read moreRead less

Summary
Influenza epidemics cause significant morbidity and mortality, particularly amongst the young and elderly. Unlike other vaccines, a new flu vaccine formulation needs to be prepared each year from the currently circulating strain. This involves a long process of preparing new seed vaccine stock, which is then tested, manufactured and distributed.

Unlike other vaccines, a new flu vaccine formulation needs to be prepared each year from the currently circulating strain. This involves a long process of preparing new seed vaccine stock, which is then tested, manufactured and distributed. The situation is even more complicated by the ability of different influenza strains to reassort with others. An example of current major concern is the possibility of deadly avian flu viruses, such as H5N1, to gain the capacity to directly infect humans by recombining with a human strain and thereby starting a new global pandemic. When the next influenza pandemic occurs, the availability of a vaccine will be of the highest priority and early supply of vaccines will save millions of lives. Since vaccination is the only sustainable defense, we face an urgent need to have the capacity to supply large numbers of vaccine doses of influenza vaccines within a short period of time. Currently, the only way of producing flu vaccines is in eggs. The speed of vaccine supply is totally dependant on the yield of vaccine from eggs and the number of eggs that can be processed at any one time. Since there are severe constraints on the number of eggs that can be simultaneously processed, the limiting factor that can be addressed is the actual yield of vaccine per egg. The aim of this project is the develop methods that allow higher levels of vaccine virus to grow in eggs. We will take a multi-pronged approach to enhancing influenza vaccine production that are directed toward increasing the capacity of eggs to promote virus replication, as well as towards the vaccine strain to boost its ability to replicate in the egg. The outcome will be an enhanced capacity for vaccine manufacturers to quickly and effectively expand vaccine supplies which will directly impact on global morbidity and mortality during a flu pandemic.Read moreRead less

Summary
In aged care service planning, the age 50 years or over is used for the Indigenous Australian population in the same way as the age 70 years is used for the non-Indigenous population. This is based on the lower life expectancy of the Indigenous population which is presumed to result in a need for aged care services at younger ages.

This is based on the lower life expectancy of the Indigenous population which is presumed to result in a need for aged care services at younger ages. The underlying assumption is that Australia's Indigenous population aged over 50 has the same set of age-associated conditions and care needs as the non-Indigenous population aged over 70. The evidence for this assumption is not established. It is well documented that the Indigenous population has worse health outcomes across all age groups relative to non-Indigenous Australians. However, our understanding of the details of the observed pattern is far from complete. This project seeks to compare the health status of the Indigenous population aged 50 years or over to the health status of the non-Indigenous population aged 70 years or over. The project will analyse a number of data sets to inform future directions in policy and service provision. A better understanding of these issues is fundamental to informed planning and allocation of resources, to identification of areas amenable to prevention strategies and to the development of approaches to care that meet the needs of Indigenous people.Read moreRead less

Summary
People with type 1 diabetes require regular insulin injections because the organ that normally makes insulin, the pancreas, no longer functions. The goal of this program is to derive human fetal pancreas tissues from embryonic stem cells. Such tissue could be used to replace the missing insulin producing cells in people with type 1 diabetes. The program brings together expertise in ES cell biology at Monash University and the leading diabetes research at the Walter and Eliza Hall Institute.
