Chocolate and iron for speedy drug delivery

Natural phenols, such as those found in chocolate, and minerals such as iron are being used to develop fast, economical drug-delivery capsules.

Frank Caruso and his team at The University of Melbourne are making nano-sized capsules that will encase vaccines and protect them from being broken down when entering the body. They believe that this delivery system will be biologically friendly and overcome a major challenge for medical materials: their compatibility with living systems.

One of the challenges of treating diseases such as cancer and HIV is delivering treatment with minimal damage to healthy areas.

Stopping parasite means more, safer meat

The world’s meat production could be lifted by 10 to 15 per cent if a vaccine can be found to combat the liver fluke.

This is the aim of a collaborative bioscience group at the new $288 million Centre for AgriBioscience (AgriBio).

An effective vaccine against liver fluke could not only boost meat production but would also lead to a large reduction in the amount of drugs given to livestock, says Prof Terry Spithill, who is co-director of AgriBio and based at La Trobe University.

Saving koalas by vaccination

The first Australian trials have started of a vaccine to prevent koalas from contracting and spreading the deadly sexually transmitted disease, chlamydia.

The trials—supervised by Prof Peter Timms and Prof Ken Beagley from Queensland University of Technology (QUT)’s Institute of Health and Biomedical Innovation—have been undertaken safely both in healthy koalas and koalas that already have chlamydial disease. All vaccinated koalas developed a good immune response to the anti-chlamydia vaccine, which shows great promise of making a significant impact on the disease in the near future.

Chlamydia is a major threat to the continued survival of koalas. Almost all populations in Australia are affected by the disease. It is a significant cause of infertility, urinary tract infections, and inflammation in the lining of the eye which often leads to blindness.

Koala numbers are declining across virtually its whole range. In the Koala Coast region of southeast Queensland in 2008 it was estimated that 2332 koalas had been lost in a three-year monitoring period. That represented a 51 per cent decrease.

By studying chlamydial disease in koalas, QUT researchers hope to understand the condition better in general. They believe their work may also hold the key to developing a successful vaccine for use against the human sexually transmitted disease Chlamydia trachomatis, a major cause of infertility in women.

VESKI’s innovative fellowships deliver results

VESKI’s main initiative – to return successful Australian expatriates with outstanding skills in science, technology and design – is paying off with some inspiring work.

In 2004, VESKI’s – Victorian Endowment for Science, Knowledge and Innovation – inaugural Fellow Professor Andrew Holmes returned from Cambridge University to work in a new $100 million Bio21 Molecular Biology and Biotechnology Institute. One of the most important research areas to emerge since has been the development of cheap plastic solar cells.

A new oral vaccine against shellfish allergies is being developed by researchers at RMIT University.

Assoc. Prof. Andreas Lopata and his team in RMIT’s School of Applied Sciences are working to help find a different method for vaccination against the potentially deadly allergy.

H1N1 still a threat

MIMR_H1N1_300x180Why does influenza make some of us much sicker than others? What are the implications for swine flu (H1N1)? Australian scientists are looking to past outbreaks for the answers.

In July 2009, the Australian Government responded to urgent global calls to use the Southern Hemisphere’s flu season as a catalyst for investigating the severity and global threat of the H1N1 flu strain.
