Summary
Tai Chi is a popular traditional health exercise that has been shown to be effective in improving health-related quality of life in aged populations and patients with acute and chronic conditions. However, the scientific evidence and mechanisms of Tai Chi at the level of the cells in the body is not clear. This project aims to investigate the mechanisms of Tai Chi to provide a better understanding of the scientific basis and offering greater confidence in using Tai Chi to promote health.

However, the scientific evidence and mechanisms of Tai Chi at the level of the cells in the body is not clear. This project aims to investigate the mechanisms of Tai Chi to provide a better understanding of the scientific basis and offering greater confidence in using Tai Chi to promote health. We propose to do a study to compare cellular measures in a group of established Tai Chi practitioners with a group who have not practised Tai Chi. It will include at least 400 members of the general public aged 30 years and over. One group will comprise long-term Tai Chi practitioners (3 years or more) and the comparison group will be those who are just starting to learn Tai Chi. The participants will come from many Tai Chi centres around Melbourne. Our collaborators (2 renowned Tai Chi teachers) will facilitate recruitment. We will collect mouth wash samples from participants and measure two major biomarkers (telomere and mitochondria). The end sections of a chromosome are called the telomere and there is evidence that telomeres get shorter as we age and when we get sick with conditions such as heart problems. Mitochondria are the powerhouse within cells that convert energy from food into a form that cells can use. The mitochondria and its function can be affected by stress in a person’s life and this might be helped by Tai Chi. Since this study aims at analysing the much-claimed benefits of Tai Chi using a scientific evidence-based approach, the two biomarkers we are planning to measure will tell us whether such benefits are reflected in the improvement of the function of cells. Using the biomarkers and some questionnaire information, we will analyse the data to see whether Tai Chi practitioners have longer telomere and better mitochondrial function than those who have not practiced Tai Chi.Read moreRead less
Complementary Medicines Based On Propolis Produced By Honeybees From Australian

Summary
Propolis produced by honeybees is a very complex mixture and its chemical composition varies in relation to its floral source. To produce propolis honey bees collect leaf bud and flowerbud exudates also secretions exuded from wounds in plants. These materials have high antibiotic activity as they have a natural function to protect delicate growing or wounded plant tissue from attack from microorganisms and animals.

To produce propolis honey bees collect leaf bud and flowerbud exudates also secretions exuded from wounds in plants. These materials have high antibiotic activity as they have a natural function to protect delicate growing or wounded plant tissue from attack from microorganisms and animals. Honey bees use propolis to sterilize the hive and to protect it against outside intruders and infection and to seal cracks in the hive. Consequently, humans have made use of propolis since ancient time for medicinal purposes. Modern research shows that a valuable property of propolis is its immunostimulant activity, now widely used in preventive medicine to boost the immune system. Furthermore, its antioxidant and anti-inflammatory properties are also believed to contribute to its current use in Complementary and Alternative Medicine (CAM). As part of research into the medicinal use of propolis produced in Australia, we identified two novel classes of biologically active constituents in Kangaroo Island (KI) propolis, which are for the first time identified to occur in propolis. Despite KI propolis being currently exported to Japan for use as CAM there is no study to determine its chemical composition or to evaluate its biological activities. Therefore we aim to research the KI propolis and evaluate its medicinal properties for use as CAM. Propolis from specific regions with defined floral sources and the identified constituents will be evaluated for their antioxidant property and protective activities against cell damaged after exposed to light source equivalent UV radiation of the sunlight with the aim to establish a defined propolis formula for topical use as CAM to prevent UV-induced skin cancers, known as melanoma, which is prevalent in Australia. This research will add value to a beekeeping product currently exported from KI and provide a health benefit.Read moreRead less
Determining The Synergistic Effects Of Complementary Medicines On Pro-inflammatory Cytokines,

Summary
Diseases like influenza, commonly called ‘the flu’, produce symptoms such as fever, headaches, lethargy and lack of appetite. What most people don’t realise is that it is not the influenza virus that produces these symptoms, but the body’s immune response to the influenza virus. This immune response comes about because the influenza virus stimulates cells to produce molecules called cytokines, and cytokines have many effects in the body, including causing fever and a lack of appetite. In severe ....Diseases like influenza, commonly called ‘the flu’, produce symptoms such as fever, headaches, lethargy and lack of appetite. What most people don’t realise is that it is not the influenza virus that produces these symptoms, but the body’s immune response to the influenza virus. This immune response comes about because the influenza virus stimulates cells to produce molecules called cytokines, and cytokines have many effects in the body, including causing fever and a lack of appetite. In severe infections like those caused by the influenza virus responsible for the pandemic of 1918, and during “bird ‘flu” (H5N1) infections, people die because the immune response becomes overwhelming. Cytokines produced during these sorts of responses are actually very harmful, even though in small amounts they help to kill the virus and cure the infection. Researchers working in this field have likened these severe responses to a “cytokine storm”. This project focusses on finding alternative therapies such as those used in Chinese medicine to prevent a cytokine storm happening, so that if an influenza pandemic occurs these treatments could be quickly made available to everyone. Examples are the Chinese herbs Angelica sinensis and Salvia miltiorrhiza. Recent laboratory studies in New York have shown that both of these herbs have potent cytokine effects, decreasing levels of an inflammatory cytokine known to be associated with death in both malaria and sepsis. Our study aims to closely examine the effects of these Chinese herbs, as well as other commercially available herbal extracts, and traditional combinations of herbs, to find synergies between them that could be used to treat severe influenza infections.Read moreRead less
Improving Evidence-based Treatment Of Latent Tuberculosis Infection In Public-hospital Based Chest Clinics

Summary
The aim of this project is to implement an electronic decision support (EDS) tool for preventive tuberculosis treatment into clinical practice. Information needs of patients and physicians as well as practical concerns regarding the use of the EDS will be evaluated before performing pilot testing and evaluating the impact of the EDS tool on simulated doctor-patient interactions and clinical workflow.

Summary
This project will deliver information in relation to the potential use and underlying modes of action of a therapeutic agent fed to pregnant mothers at high risk for atopic children, to protect against allergic asthma development in their offspring. Furthermore, the project will address the benefits of this therapeutic agent in relation to protection against inflammation induced preterm birth.
A Randomised Controlled Trial Of Interventional Versus Conservative Treatment Of Primary Spontaneous Pneumothorax

Summary
Primary spontaneous pneumothorax (PSP) is a collapsed lung that occurs in otherwise healthy people without underlying lung disease. Current standard treatment is to insert a chest drain into the chest to remove the air around the collapsed lung so that the lung re-inflates rapidly ("interventional treatment"). We will determine whether doing nothing, i.e. letting the lung re-inflate slowly on its own over several weeks ("conservative treatment"), is just as good or even better for patients.
