Is Calcium part of the mechanism used in glucose signalling in embryogenesis. A vital stage in the development of the embryo is formation of the blastocyst about 4 days after conception. For this to happen the embryo must receive glucose from the mother. We believe that rather being used by the embryo to generate energy, this glucose acts as a signal to switch on the developmental pathway leading to blastocyst formation. Without this signal there is no blastocyst and the pregnancy fails. The pr ....Is Calcium part of the mechanism used in glucose signalling in embryogenesis.

We believe that rather being used by the embryo to generate energy, this glucose acts as a signal to switch on the developmental pathway leading to blastocyst formation. Without this signal there is no blastocyst and the pregnancy fails. The project investigates this signal mechanism. The results will advance understanding of the mechanisms regulating development and in particular link the mother's nutritive status to her fertility during very early pregnancy.Read moreRead less
Membrane excitability and cellular calcium regulation in the peripheral nervous system under different (patho)-physiological conditions and in inflammatory disease. Studies of cytokine action on neurons and muscle give new insights into functional responses of the nervous system to systemic inflammation and sepsis. In some countries, sepsis is the third most frequent cause of death following heart attack. Elucidating the pathomechanisms allows to develop therapeutic strategies. Electrophysiology ....Membrane excitability and cellular calcium regulation in the peripheral nervous system under different (patho)-physiological conditions and in inflammatory disease. Studies of cytokine action on neurons and muscle give new insights into functional responses of the nervous system to systemic inflammation and sepsis. In some countries, sepsis is the third most frequent cause of death following heart attack. Elucidating the pathomechanisms allows to develop therapeutic strategies. Electrophysiology, Ca2+ regulation and optical membrane potentiometry allow us to monitor early changes in disease on a (sub)cellular level. Experiments on Ca2+ regulation and ion channel function in muscle with different cholesterol membrane contents will help to understand pathomechanisms in high cholesterol diseases, e.g. obesity, on the membrane level long before cardiovascular effects become prominent.Read moreRead less
Opportunities of Media and Communication Technology to Support Social Networks of Urban Residents in Mexico, South Africa, UK and Australia. This project will build advanced knowledge of how urban neighbourhood communities can be assisted to grow in healthy ways by the use of new media and Information and Communications Technologies (ICTs). By careful attention to cultural and social assets in the community, innovations will be engendered which enhance economic and social development. This will ....Opportunities of Media and Communication Technology to Support Social Networks of Urban Residents in Mexico, South Africa, UK and Australia. This project will build advanced knowledge of how urban neighbourhood communities can be assisted to grow in healthy ways by the use of new media and Information and Communications Technologies (ICTs). By careful attention to cultural and social assets in the community, innovations will be engendered which enhance economic and social development. This will lead to greater social inclusion, fair access to and smart use of information and services, urban sustainability and healthier local economies. Understanding the opportunities afforded by digital augmentation of social networks will help Australians negotiate the complex web of daily choices, access a greater social safety net and participate in the socio-cultural and socio-economic life of their neighbourhood and city.Read moreRead less
Raman spectroscopy and imaging of natural and synthetic melanins. The national benefit of this research lies in three main areas. First, this research could lead to a non-invasive diagnostic for melanoma. Second, it could reveal stronger connections between melanin and melanoma development than previously believed and thus inspire possible methods of treatment or prevention of melanoma. Given Australia's high incidence of melanoma, these could have an enormous impact on our health care system. T ....Raman spectroscopy and imaging of natural and synthetic melanins.

Second, it could reveal stronger connections between melanin and melanoma development than previously believed and thus inspire possible methods of treatment or prevention of melanoma. Given Australia's high incidence of melanoma, these could have an enormous impact on our health care system. Third, it will increase our understanding of the melanin pigment and further establish Australia as a leader in this field. Given the links between melanin and Parkinson's Disease and immune response, this understanding could have greater impact on health care than simply melanoma.Read moreRead less
Design and evaluation of new environmentally-benign herbicides that inhibit branched-chain amino acid biosynthesis. Herbicides interfere with processes that occur in plants, such as photosynthesis or the biosynthesis of certain amino acids. In this project we will focus on branched-chain amino acid biosynthesis, designing and evaluating inhibitors of the first two enzymes in this process. Based on their three dimensional structures we will develop an understanding of the molecular features that ....Design and evaluation of new environmentally-benign herbicides that inhibit branched-chain amino acid biosynthesis. Herbicides interfere with processes that occur in plants, such as photosynthesis or the biosynthesis of certain amino acids. In this project we will focus on branched-chain amino acid biosynthesis, designing and evaluating inhibitors of the first two enzymes in this process. Based on their three dimensional structures we will develop an understanding of the molecular features that contribute to a potent inhibitor and those that are required for it to be effective upon plants. Using this information we will design and synthesis new compounds as potential environmentally-benign herbicides.Read moreRead less
