Summary
The objective of the ENERGY project is to examine the influence of existing programs on health behaviours in different populations and settings in order to develop an evidence and theory-based approach for promoting physical activity and healthy eating among youth in transition from childhood to adolescence. The results of this project will be translated into practical strategies and knowledge that can be used by schools, policymakers, health professionals and the general public.

The results of this project will be translated into practical strategies and knowledge that can be used by schools, policymakers, health professionals and the general public. The ENERGY project involves a multidisciplinary team of investigators from 10 European countries and Australia (Deakin University; DU). DU will participate in two of the 10 work packages (WP) in the proposal. The aim of WP3 is to identify the personal, social and physical environmental determinants in family and school of children’s physical activity and healthy eating. The aim of WP5 is to identify moderators and mediators of successful interventions to prevent obesity among children aged 10-12 years.Read moreRead less

Summary
Obesity is a rapidly escalating, worldwide epidemic. Many countries recognise the need to prevent obesity but there is insufficient evidence about what interventions work. The Pacific Obesity Prevention in Communities (OPIC) Project will provide data on the effectiveness of a range of interventions to prevent obesity among young people in Fiji, Tonga, New Zealand and Australia.

Many countries recognise the need to prevent obesity but there is insufficient evidence about what interventions work. The Pacific Obesity Prevention in Communities (OPIC) Project will provide data on the effectiveness of a range of interventions to prevent obesity among young people in Fiji, Tonga, New Zealand and Australia. Prevention research is particularly required in countries such as Fiji and Tonga because their prevalence of obesity is extremely high. The interventions used in this project will be culturally appropriate and include at least 1000 young people in each intervention group. The outcomes of this project will be applicable to both low- and high-income countries. This project will lead to a greater understanding of the socio-cultural, policy, and economic contexts and provide crucial evidence for public health action to prevent obesity.Read moreRead less
Approaches to combat AIDS and its causative agent, the human immunodeficiency virus HIV-1, have thus far proved ineffective. The proposed research program intends to investigate the nuclear import of two HIV-1 proteins which have central roles in HIV infection.

The proposed research program intends to investigate the nuclear import of two HIV-1 proteins which have central roles in HIV infection. We will apply our expertise in the area of the regulation of nuclear import of viral proteins, and build on our observations with respect to these proteins to attempt to establish the mechanistic basis of their nuclear import, and how this differs from the conventional nuclear import pathways used by normal cellular proteins. We already have evidence that nuclear import of HIV-Tat is regulated in novel fashion by cellular factors, and intend, through determining its mechanistic basis, to be able to form the basis of a strategy to block this import pathway specifically, and thereby inhibit HIV replication. This may form the basis in the future of a new pharmaceutical approach to combat HIV-AIDS.Read moreRead less
HIV infection of CD4+ lymphocytes leads to a high rate of reproduction of new virus. However, in the brain, HIV infection of the astrocytes does not yield high levels of new virus. HIV is genetically active in these astrocytes, producing high levels of the messenger molecules, the so-called mRNA, that code for the proteins required for a new virus particle. We have determined that these HIV mRNAs are specifically prevented from translating into protein. The mechanisms controlling protein transla ....HIV infection of CD4+ lymphocytes leads to a high rate of reproduction of new virus. However, in the brain, HIV infection of the astrocytes does not yield high levels of new virus. HIV is genetically active in these astrocytes, producing high levels of the messenger molecules, the so-called mRNA, that code for the proteins required for a new virus particle. We have determined that these HIV mRNAs are specifically prevented from translating into protein. The mechanisms controlling protein translation from RNA are relatively poorly understood compared with the other control points of cellular gene expression, such as the synthesis of mRNA. This project examines how astrocytes rapidly detect the presence of HIV mRNA and alter their translation machinery to halt the expression of HIV protein. This host defence mechanism involves two key components; the cellular component that identifies and responds to the viral mRNA, and the structural features of the HIV mRNA that enable the cell to detect its viral origin. We will study how translation of HIV proteins requires both HIV and cellular factors. We will determine the impact of both viral RNA elements and viral RNA binding proteins on the translation of viral and cellular proteins. The contribution of the type-1 interferons that are produced in response to viral infection will be studied for their role in augmenting the inhibition of HIV protein translation. Since HIV infected astrocytes significantly contribute to the onset of AIDS dementia, we will sees a strategy to lock HIV into a dormant state in the brain and thereby prevent the neurodegenerative disease associated with HIV. We will use the anti-viral mechanism blocking HIV protein translation in astrocytes to protect other cell populations, such as the CD4+ lymphocytes, from HIV infection. These studies will also give insights into the general mechanisms for translational control of gene expression in human cells.Read moreRead less
