Summary
The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence.

The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells use epigenetic changes to help control how they grow and develop. Evidence suggests a direct link between diet and environmental influences on our epigenetic profile. Recent research has traced the origins of many of the health problems of adult life back to the earliest periods of development _ to the time spent in the womb and the first few years of life. If we are born with a low birth weight, we are more likely to get sick later in life. Overwhelming evidence exists that the environment in the womb is critical for a healthy birth weight (and health in later life) and it is thought that epigenetics may be the missing link between this environment, low birth weight, and therefore health in later life. In addition, mounting evidence supports a general link between epigenetic de-regulation and predisposition to disease. However, the timing and the overall contribution of environmental- genetic influences to the establishment of faulty epigenetic markings remain largely unknown. Twins are the best model to study this link as they share similar (but not identical environments) and some share identical genetic makeup. Using twins, Dr Jeffrey Craig and his team will investigate the factors in the prenatal environment that modify specific cells, leading to low birth weight and increase disease risk later in life. They predict that this occurs via specific changes in gene activity caused by epigenetic disruption.Read moreRead less

Summary
The research aims to improve outcomes for Aboriginal people with chronic disease, through strategies of care that address health system barriers. The project aims to understand barriers and then to develop, implement and evaluate appropriate models of care that incorporate policy development and engagement. The project is to incorporate research partnerships and Indigenous sector capacity development.

Summary
In this project new DNA-based technology will be developed to determine the numbers of specific bacteria in the dental plaque of patients. The project will also use new mass spectrometric analysis techniques for the determination of compounds in gingival crevicular fluid, an exudate from the gums. These two techniques will be used in a clinical trial to determine if periodontal (gum) disease progression can be predicted by changes in the numbers of bacteria or in the composition of gingival crev ....In this project new DNA-based technology will be developed to determine the numbers of specific bacteria in the dental plaque of patients.

These two techniques will be used in a clinical trial to determine if periodontal (gum) disease progression can be predicted by changes in the numbers of bacteria or in the composition of gingival crevicular fluid. This could provide insight into the development of periodontal disease and lead to new preventive and treatment regimes.Read moreRead less
Early Intervention For Amnestic Mild Cognitive Impairment : A Randomised Trial Of Memory Management

Summary
It is increasingly recognised that Alzheimer’s disease can emerge slowly over years and persons presenting with memory impairment, or mild cognitive impairment (MCI), are at increased risk of developing Alzheimer’s disease. Following diagnosis of MCI, active management through symptomatic drug treatment remains equivocal, therefore, memory impairment continues to be troublesome and patients and families are seeking interventions that offer improvement in quality of life. Cognitive interventions ....It is increasingly recognised that Alzheimer’s disease can emerge slowly over years and persons presenting with memory impairment, or mild cognitive impairment (MCI), are at increased risk of developing Alzheimer’s disease. Following diagnosis of MCI, active management through symptomatic drug treatment remains equivocal, therefore, memory impairment continues to be troublesome and patients and families are seeking interventions that offer improvement in quality of life. Cognitive interventions are low cost and, where effective, can provide a stand-alone intervention or add value to the pharmacological approach. The primary aim of this study is to evaluate whether an early intervention program of memory training is effective in improving use of memory strategies in everyday life, and whether this has psychological and emotional benefits for individuals with MCI and their families. We will evaluate through a randomised controlled trial the efficacy of a memory-group program which will involve the family and patient, rather than just the person with MCI, in developing increased awareness of memory issues and specific strategies to prevent memory failures. Over successive cohorts recruited from memory clinics, families will be randomly assigned to either an immediate intervention or a delayed intervention (waiting-list control) group. We will also recruit a sample of healthy older adults who will be similarly randomised into early and late intervention groups. Healthy older adults will provide a means of establishing whether any improvements in the MCI groups are (i) to the same extent as healthy older adults and (ii) to normative levels. Evaluation will be at pre- and post-intervention and at six months follow-up on tests of memory, questionnaires of knowledge and use of memory strategies in everyday life, and appraisal of level of wellbeing. Information about memory and systematic training in compensatory memory skills are expected to significantly improve the capacity of patients and families to cope with everyday memory difficulties. Through active participation in the management of memory impairment, it is expected that the level of wellbeing will increase, for both patient and families.Read moreRead less
