Summary
Streptococcus pneumoniae (Pnc) is the leading vaccine preventable cause of serious infection in infants. The current Pnc conjugate vaccine is very expensive (approximately USD $200-infant) so it is unlikely to be affordable for most developing countries. Moreover, as health care access in developing countries may be episodic and unreliable, many children do not receive either complete or timely vaccine courses. Therefore, it is important to investigate affordable and flexible ways to deliver thi ....Streptococcus pneumoniae (Pnc) is the leading vaccine preventable cause of serious infection in infants. The current Pnc conjugate vaccine is very expensive (approximately USD $200-infant) so it is unlikely to be affordable for most developing countries. Moreover, as health care access in developing countries may be episodic and unreliable, many children do not receive either complete or timely vaccine courses. Therefore, it is important to investigate affordable and flexible ways to deliver this vaccine, which are safe and effective. A recent WHO-GAVI meeting to address impediments to the introduction of these vaccines in developing countries recognized the need to evaluate other regimens of Pnc conjugate vaccine as an important research priority. This study has been deliberately formulated with that need in mind. The site for this research is Fiji. Although health services are good, Pnc disease, particularly pneumonia, remains the commonest cause of childhood morbidity and mortality. Fiji has good vaccine coverage and was the first Pacific country to introduce Hib vaccine. The arrival of the new, expensive Pnc conjugate vaccine presents a dilemma for Fiji and many similar countries. The expense of this vaccine would consume a large portion of the health budget. This study has two components: 1. A Phase 2 immunogenicity study (involving 750 infants) to evaluate regimens using reduced numbers of doses of Pnc conjugate vaccine, and using timing of dosing and combinations with the Pnc polysaccharide (PS) vaccine that may be more suited to the epidemiology of Pnc disease in developing countries. 2. An epidemiological study will measure the burden of invasive Pnc disease and pneumonia in Fiji. This will be part of a global effort to address these issues, and will be used to develop rapid assessment tools for these diseases in developing countries. We will seek cofounding for this component.Read moreRead less
Respiratory failure at birth is a major cause of death and disease in newborn infants. At birth the airways must be cleared of liquid to allow the inhalation of air, but, little is known about the process of lung aeration, because it has not been possible to observe or measure it. We have developed imaging and analytical techniques to observed and measure lung aeration. We will determine ventilation procedures that promote uniform lung aeration and minimise lung injury in ventilated infants.
Polynuclear Metal Complexes as Molecular Nanomagnets. Computer hard drives and other devices use tiny particles of magnetic materials to store digital information. Technological advances require an increase in the density of information storage and therefore even smaller magnetic particles. This project has the potential to synthesise materials where a single molecule could act as the smallest possible unit of magnetic memory. The future application of these materials may provide an increase ....Polynuclear Metal Complexes as Molecular Nanomagnets. Computer hard drives and other devices use tiny particles of magnetic materials to store digital information. Technological advances require an increase in the density of information storage and therefore even smaller magnetic particles. This project has the potential to synthesise materials where a single molecule could act as the smallest possible unit of magnetic memory. The future application of these materials may provide an increase of three orders of magnitude in information storage density. In addition, they may find employment in quantum computers, which can perform calculations exponentially faster than conventional computers.Read moreRead less

Molybdenum enzymes play key roles in biology and environmental, biogeochemical and meteorological processes. This international, multidisciplinary project will employ advanced synthetic, instrumental and theoretical techniques to establish the link between electronic structures and molybdenum enzyme behaviour and function. The insights gained will inform the continuing development of agricultural, veterinary and medical treatments for diseases associated with enzyme dysfunction; these outcomes would be of enormous economic and societal benefit to Australia. The training of skilled scientists, access to advanced overseas facilities, and international recognition of Australian research, are important immediate benefits of the project.Read moreRead less

The goal of this project is to create materials where individual molecules can be the units of magnetic memory for high density data storage or the switches in electronic devices. Fundamental research in these areas is being pursued vigourously overseas and Australian involvement through this project is important for the possibility of local development of devices based on the new materials.

Alzheimer's disease is the most common form of dementia and affects over 160,000 Australians. The imaging agent market is a niche biotechnology industry in which Australia already has an international presence. The proposed research will lead to innovations to ensure Australia remains internationally competitive in this area. This research has potential social and economic benefits for the nation.Read moreRead less

Summary
Colorectal cancer (CRC) is the third most common cancer worldwide. About half of all patients diagnosed with the disease die as a result of its spread in the body. This project will investigate the role that a specific DNA-binding protein plays in orchestrating gene expression programs required for CRCs to spread. The research will provide new insights into underlying mechanisms of CRC progression as well as identify new therapeutic targets for aggressive forms of the disease.

This project aims to improve the performance and longevity of molecular photocatalysts to produce hydrogen from water and visible light. Sustainable alternatives to fossils fuels, such as hydrogen, are critical to minimising the effects of climate change. This project expects to use innovative experimental techniques to reveal the causes of degradation in key intermediates of the photocatalytic reaction. Understanding these detrimental pathways can then direct the design of new catalysts with enhanced stability and activity. The fundamental chemistry explored in this project should advance breakthroughs in artificial photosynthesis and provide cleaner methods of hydrogen production under mild conditions, using earth-abundant catalysts.Read moreRead less

Carbonate's ability to bring associated metal centres into close communication may lead to unusual and possibly useful electrical, magnetic and catalytic properties. The ability to deliberately engineer specifically targeted coordination polymers with predetermined properties or functions would make possible diverse applications of great practical value; the project will contribute significantly to the basis for such capabilities leading to ?designer materials? of the future.Read moreRead less
