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.

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

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

Although traditionally administered as a dietary supplement, recently there has been considerable excitement in the psychiatric community due to its ability to improve schizophrenia symptoms when administered in conjunction with mainstream medications. However, two issues need to be resolved in order for glycine to be employed as a routine therapy in schizophrenia. Firstly, this treatment is only effective in some patients, and we have no way of determining which patients will benefit from glycine. Secondly, there are both theoretical reasons and experimental evidence that glycine administration can cause severe impairment for some individuals. Thus although there is great potential for glycine to ease the burden of schizophrenia symptoms, these two issues need to be resolved before this possibility can be actualised. Theoretical considerations, supported by pilot research of the investigators, point to the view that schizophrenia patients’ baseline glycine level is the critical factor that determines whether a patient will benefit or be impaired by glycine therapy. This thesis offers a testable means with which to resolve the above limitations to the use of glycine. The purpose of the current research program is thus to provide the basis for rational prescription of glycine as an additional therapeutic tool in schizophrenia.Read moreRead less

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.

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

Products are advertised as safe despite the fact that many have never been systematically tested for either efficacy or safety. Little is known about the potential for herbal medicines to interact with conventional medicines which may lead to potentially serious consequences. Clinical reports suggest that there is potential for an interaction between warfarin and herbal medicines. Interactions with warfarin in patients receiving the drug as part of their therapy can be life threatening. Identifying and avoiding significant drug interactions with warfarin can reduce patient problems caused by excessive bleeding, reduce length of hospital stay and decrease the need for frequent blood monitoring. The present study design will also provide a valuable insight into possible interactions with other medicines by understanding the mechanism of possible herb-drug interactions.Read moreRead less

Such work will provide an evidence-base for policy and practice on this topic and the project findings will help develop CAM initiatives and programs for women’s health that are sensitive to geographical variations in community health, health practice and provision. Women are significantly more likely to utilise CAM treatments than males and mid-age women have been found to be the highest CAM user group amongst Australian women. Researchers and practitioners have identified treatments from within CAM as potentially well-suited to dealing with a range of health problems and associated symptoms prevalent amongst mid-age women including the onset of cancer, arthritis, diabetes and asthma as well as menopause. Our previous pilot work found that mid-age women in regional areas are significantly more likely to use CAM than those in urban areas. A number of explanations as to why this is so can be or have been proposed. These include: limited access to conventional health care services in regional areas; closer working ties between non-urban general practitioners and CAM provision; dissatisfaction with conventional health care services in regional areas and stronger informal community networks in nonurban areas. Our proposed project, drawing upon a national representative sample of mid-age women will test such hypotheses and will provide findings of benefit and interest to policy makers, practitioners, consumers and all involved in women’s health and health care across urban and regional Australia.Read moreRead less

Summary
An emerging approach to treat depression is via the use of adjunctive nutraceuticals (nutrient-based natural products). Specific antidepressant nutraceuticals can target a range of key neurological pathways that can treat depression. We are conducting an 8 week clinical trial comparing the efficacy of a range of nutraceuticals- such as folic acid, omega-3, and zinc, in adults with depression who are non-responsive to current pharmaceutical antidepressants.
