Fighting disease together

Malaria kills 500,000 people every year. And 90 per cent of those are children. Griffith University researchers are screening hundreds of thousands of compounds supplied by Japanese companies to find the right compound with activity against the malaria parasite.

Japan’s Global Health Innovative Technology Fund is supporting the research as part of their search for new ways to fight malaria.

“GHIT is a fund that invests in partnerships between Japanese and non-Japanese entities,” says BT Slingsby, the Executive Director of GHIT.

“Many of those entities are in Australia including The University of Melbourne, The Walter and Eliza Hall Institute, and Griffith University.”

“Currently we’re working with companies such as Daiichi-Sankyo, Takeda, Mitsubishi Tanabe, and Eisai,” says Griffith University’s Vicky Avery. 

They bring those compounds to us. We then dispense them into plates which contain the parasite we’re trying to kill.  After they’ve been incubated for a period of time we then look to see whether they’ve had an effect in killing the parasites.

“Once one defines a hit, usually it’s the pharmaceutical company that drives forward the further development of that compound to create a drug.

“This collaboration is fantastic in that it has three groups who complement each other,” Vicky says.

The Japanese pharma companies bring expertise in drug discovery and development.  GHIT has managed to pull together significant funding from both global partners as well as the Japanese Government. And Griffith University brings the biology expertise.

Turning off toxic T cells in MS clinical trial

Switching off T cells before they begin to damage the nervous system is the basis of an Australian therapy for multiple sclerosis (MS), which is expected to begin clinical trials by the end of 2017.

Developed by researchers at Victoria University in western Melbourne and the University of Patras in Greece, it brings together peptides, or protein fragments, with a biochemical delivery system already shown to be effective in cancer vaccine clinical trials.

A scarce Sarah: new blood group making transfusions safer

Further research into a rare blood type first recorded in Australia 20 years ago will continue to make transfusions and pregnancies safer for others.

“Now families with the SARA blood type can be tested for the gene and this will help safely manage future pregnancies,” says Associate Professor Catherine Hyland of the Australian Red Cross Blood Service.

“This genetic testing has implications for others, particularly since similar problems can occur during transfusion or pregnancy for people with similar rare blood types.”

Blood types are more complex than simply combinations of ‘positive’ and ‘negative’ with A, B, O, or Rh—there are hundreds of different antigens (proteins and sugars on the surface of our cells) across the 36-plus blood groups.

In the 1990s, the Australian Red Cross Blood Service realised the antigens on a special donor named Sarah’s red blood cells weren’t like any previously recorded. But it wasn’t until 2010 that the unusual antigen was investigated again: the Canadian Blood Service reported that a pregnant woman’s immune system had begun attacking her foetus, which they suspected had inherited the same rare blood type recorded in Australia.

Robotic arm to help stroke patients regain movement

A robotic arm is the key to a radical new stroke treatment, helping patients regain upper body movement.

Melbourne researchers have developed a device that helps stroke patients learn to use their bodies again by tracking their movements while performing exercises. The arm movements can be displayed on a computer screen, and the activities turned into a game.

“The patients enjoy using the robot because it’s like playing computer games,” says Associate Professors Denny Oetomo, who is working with Ying Tan, and a team at The University of Melbourne and Royal Melbourne Hospital.

“It also improves the ratio of patients to clinician time as the clinicians can handle multiple patients at one time.” Continue reading Robotic arm to help stroke patients regain movement

The right juice for your heart

Beetroot juice and exercise are being investigated as a treatment for cardiovascular problems. And understanding the workings of the combination could lead to other, more sophisticated therapies.

That’s the hope of Professor Jason Allen and his PhD student Mary Woessner from the Institute of Sport, Exercise and Active Living (ISEAL) at Victoria University in western Melbourne. Continue reading The right juice for your heart

Sharpening vision in bionic eyes

A PhD student at The University of Melbourne has discovered a technique that can improve the resolution of bionic eyes for people who suffer from retinal conditions such age-related macular degeneration and retinitis pigmentosa.

“Implants are really limited in how much resolution they can provide. I’m trying to improve that,” says Kerry Halupka, who works with the Bionics Institute. Continue reading Sharpening vision in bionic eyes

Keeping in shape: what happens to red blood cells in storage?

Understanding why red blood cells get out of shape during storage could help improve the effectiveness and safety of blood transfusions.

So, Marie-Anne Balanant and Sarah Barns are combining biological and engineering expertise, to create a model of how different parts of ageing red blood cell membranes react when a force is applied.

They hope to propose strategies to improve blood storage practices and create better transfusion outcomes for patients.

Measuring the risk of an Australian Zika outbreak

The conditions have been right for Zika virus to spread during the warmer months of past years in Townsville, Cairns and Rockhampton, according to research led by the Australian Red Cross Blood Service.

Using temperature data from January 2015 to December 2016, the team modelled the ability of mosquitoes to spread the virus in four Queensland cities. Brisbane (the fourth city) was the only site where the risk was low.  

“If locations experience outbreaks of dengue, the conditions would also be right for outbreaks of Zika,” says lead researcher Dr Elvina Viennet.

The findings emphasise the need for imported cases to be reported immediately, Elvina says.

Rehabilitating mangrove forests may help combat climate change

Twenty hectares of old, abandoned fish ponds have been rehabilitated into mangrove forests in Tiwoho, in Indonesia’s North Sulawesi.

Their efficiency in capturing and storing carbon from the atmosphere is being put to the test by researchers, in the hopes the rehabilitation process can help mitigate the effects of climate change and restore the provision of ecosystem services, such as fisheries, provided by healthy mangroves.

Changing the minds of dementia patients

“I’m ecstatic about the impact our programs have on kids, and knowing that we’ve changed their lives for the better. But we need to ask ‘what about our retirees?’” says Professor Ron Rapee, ARC Laureate Fellow, and former Director of the Centre for Emotional Health.

Retirees are less likely to suffer from mental health problems but they still develop anxiety and depression – and there’s increasing evidence these conditions are risk factors for dementia.

To make things worse, they’re often left untreated as there’s a perception that it’s normal for older people to suffer depression as they lose their friends, health and independence.
