Summary
It is widely recognized that diet and exercise have a major influence on the health and fitness. Sedentary lifestyles predispose people to obesity and the early development of age onset diseases. In the past decade we have gained considerable insight into the regulatory links between exercise and metabolism particularly involving the AMPK signalling pathway. This project is concerned with the phosphoproteome of trained and untrained skeletal muscle, fat and erythrocytes as a marker of fitness.

An influenza pandemic causing by highly pathogenic H5N1 virus may occur in the near future. As a vaccine for H5N1 will not be available in the foreseeable months, antiviral drugs are the only possible choice for prophylaxis and treatment. Currently only two drugs have been clinically proven to be effective against H5N1 strain and the emergence of drug resistant in H5N1 influenza virus has been reported which may significantly hamper the treatment.

As a vaccine for H5N1 will not be available in the foreseeable months, antiviral drugs are the only possible choice for prophylaxis and treatment. Currently only two drugs have been clinically proven to be effective against H5N1 strain and the emergence of drug resistant in H5N1 influenza virus has been reported which may significantly hamper the treatment. Understanding and monitoring the emergence of these drug resistant strains during local spreading will be critical in managing an H5N1 influenza pandemic in Australia. In the proposed project, we will develop important diagnostic tools using our world leading Rolling Circle Amplification (RCA) technology for the monitoring of the development and possible transmission of drug resistant influenza strains. Upon finishing the project, at lease three sensitive diagnostic methods will be developed for the detection of the emergence of drug resistance at the very early stage.Read moreRead less

Summary
Omega-3 fats are a type of polyunsaturated fat which has long been thought to be beneficial for health. The body cannot make its own omega-3 fats - they must be taken in through the diet, or in supplement form. Large population-based studies have suggested that a diet rich in omega-3 fats can reduce the risk of cardiovascular disease, lower blood pressure, cut the risk of cancers such as prostate and skin. The fats have also been touted as a treatment for arthritis, asthma, and inflamed bowels. ....Omega-3 fats are a type of polyunsaturated fat which has long been thought to be beneficial for health. The body cannot make its own omega-3 fats - they must be taken in through the diet, or in supplement form. Large population-based studies have suggested that a diet rich in omega-3 fats can reduce the risk of cardiovascular disease, lower blood pressure, cut the risk of cancers such as prostate and skin. The fats have also been touted as a treatment for arthritis, asthma, and inflamed bowels. A lack of omega-3s during foetal development can hinder brain and eye development. Other work has suggested that a diet rich in omega-3 may help improve mental health. Studies revealed beneficial effects in a broad range of mental health problems including violent and aggressive behaviour in teenagers, major depression, bipolar affective disorder, borderline personality disorder, and schizophrenia. Evidence that omega-3 fatty acids may reduce symptoms in schizophrenia and other major psychiatric disorders make omega-3 fatty acids an optimal candidate for further evaluation of its therapeutic efficacy, in particular in young people in early illness stages of psychosis where specific intervention is controversial due to potential risks and medication side-effects. The proposed 12-week intervention study aims to establish a new treatment strategy alternative to antipsychotic medication in the young people with subthreshold symptoms at high risk for psychosis. Omega-3 fatty acids have no clinically relevant side effects which often accompany therapy with antipsychotics (such as diabetes and weight gain). A widely available, easy applicable, biological treatment without clinically relevant side effects could help to improve compliance and outcome in psychosis. Schizophrenia is often prolonged and results in a considerable economic burden. Early treatment has the potential to offset future costs to both mental health providers and the recipients of these services.Read moreRead less

Summary
The neuraminidase (NA) inhibitors are considered the most effective anti-influenza drugs available for both prevention and treatment of influenza virus infection including A(H5N1) viruses. The drugs are effective against all subtypes of influenza A, making them ideal for use in the early months of a pandemic prior to an appropriate vaccine being produced.

The drugs are effective against all subtypes of influenza A, making them ideal for use in the early months of a pandemic prior to an appropriate vaccine being produced. As a result many countries around the world, including Australia, have stockpiled these drugs (mainly Tamiflu) as part of their pandemic preparedness plans. However, of concern is the increasing number of recent reports of a higher than expected level of resistance in epidemic influenza being generated against these drugs. A recent isolation of an H5N1 virus from a Vietnamese girl highlights that these viruses can also be resistant to Tamiflu. Within Australia, Tamiflu will be a critical weapon against the initial wave of an influenza pandemic, therefore it is vital that more is known about the propensity of the H5N1 virus to generate resistance, and possibly make these drugs clinically less effective. The aim of the project is to determine the levels, mode and type of resistance that may occur when ferrets are experimentally infected with HP A(H5N1) virus and then treated with NA inhibitors drugs such as Tamiflu. In the event of resistant viruses being isolated following drug pressure from Tamiflu, the strains will then be tested for their sensitivity to the other NA inhibitor drugs Relenza (zanamivir) or the peramivir (a third currently unlicensed NA inhibitor). The results from this cross resistance work will allow strategies to be put into place regarding the administration of an alternative NA inhibitor in the event of a pandemic virus acquiring particular NA mutations which may for example result in Tamiflu resistance. To determine the relative human risk of a NA inhibitor resistant A(H5N1) virus, studies to determine how infectious or transmissible the viruses are would be performed on all resistant strains isolated. NA inhibitor resistant strains demonstrate varying degrees of transmissibility and fitness, therefore it would be beneficial to classify this for any strains generated from this study so as to be in a better position to understand the public health implications if a particular resistant strain was to arise.Read moreRead less

Summary
Infection with a virulent influenza virus that the body has never encountered before, particularly H5N1, sends the immune system into overdrive, and causes a massive release of proteins (inflammatory cytokines), known as a cytokine storm, that in and of itself leads to death. The object of this research is to screen, in a mouse influenza model, agents known to prevent this occurring and antagonise it once it has occurred. This will be done with and without Tamiflu, a standard anti-influenza drug ....Infection with a virulent influenza virus that the body has never encountered before, particularly H5N1, sends the immune system into overdrive, and causes a massive release of proteins (inflammatory cytokines), known as a cytokine storm, that in and of itself leads to death.
