New software tool could help better understand childhood cancer

(Press-News.org)

New cutting-edge software developed in Melbourne can help uncover how the most common heart tumour in children forms and changes. And the technology has the potential to further our understanding of other childhood diseases, according to a new study.

The research, led by Murdoch Children’s Research Institute (MCRI) and published in Genome Biology, found the software, VR-Omics, can identify previously undetected cell activities of cardiac rhabdomyoma, a type of benign heart tumour.

Developed by MCRI’s Professor Mirana Ramialison, VR-Omics is the first tool capable of analysing and visualising data in both 2D and 3D virtual reality environments. The innovative technology aims to analyse the spatial genetic makeup of human tissue to better understand a specific disease.

Cardiac rhabdomyoma, usually detected during pregnancy or infancy, doesn’t cause health problems in most cases. But in some babies and children the tumours can grow and block blood flow to vital organs, causing respiratory distress, irregular heartbeat, obstructions and heart failure.

“When the tumours cause severe health complications, treatment options are limited and include surgically removing part of the heart, which may lead to further complications and death,” Professor Ramialison said. Unfortunately, it’s not well understood why these tumours form.”

To challenge her new software, Professor Ramialison and her team, including Denis Bienroth and Natalie Charitakis, analysed heart tissue from three children in Melbourne with cardiac rhabdomyoma. In a breakthrough, the research uncovered specific underlying features of the tumour that hadn’t been identified previously.

Professor Ramialison said the VR-Omics tool would help researchers to gain a better insight into the disease.

“VR-Omics generates 3D visualisations of the cells within human tissue based on large collections of patient data,” she said. This could allow for greater analysis of human tissue compared to other methods.”

Professor Ramialison also benchmarked the software against existing state-of-the-art methods, finding it performed better in all analysis steps.

“VR-Omics has a unique capacity to analyse large datasets, which allows it to explore new biological mechanisms in rare tissue sections, like those from cardiac rhabdomyoma,” she said. The technology will enable more biological discoveries that could help better understand many childhood conditions.”

Researchers from the Melbourne Centre for Cardiovascular Genomics and Regenerative Medicine (CardioRegen), the University of Konstanz in Germany, Novo Nordisk Foundation Center for Stem Cell Medicine (reNEW), University of Melbourne and Monash University also contributed to the findings.

Healthy lifestyle linked to lower diverticulitis risk, irrespective of genetic susceptibility

2025-07-01
Maintaining a healthy lifestyle—specifically, a diet rich in fibre but light on red/processed meat, regular exercise, not smoking, and sticking to a normal weight—is linked to a significantly lower risk of diverticulitis, finds a large long term study, published online in the journal Gut. What’s more, these 5 components seem to offset the effects of inherited genes, the findings indicate. Diverticulitis occurs when ‘pouches’ develop along the gut and become inflamed or infected in the wall of the large intestine (colon), explain the researchers. It’s a common cause of hospital admissions and a major reason for emergency colon surgery, they add. Genetic ...

Women 65+ still at heightened risk of cervical cancer caused by HPV

2025-07-01
Women aged 65 and above are still at heightened risk of cervical cancer caused by human papillomavirus (HPV), suggest the findings of a large observational study published in the open access journal Gynecology and Obstetrics Clinical Medicine. But most guidelines currently recommend discontinuing screening for the disease in women aged 65+ if they have had previously normal smear tests. Yet global cases of cervical cancer have been rising among women in this age group, prompting the researchers to call for a policy rethink. Recent data from the World Health Organization indicate that ...

‘Inflammatory’ diet during pregnancy may raise child’s diabetes type 1 risk

2025-07-01
A diet high in foods with the potential to promote low grade inflammation during pregnancy may raise that child’s risk of developing type 1 diabetes, suggests Danish research published online in the Journal of Epidemiology & Community Health. This dietary pattern was associated with a 16% heightened risk for every unit increase in a dietary measure of inflammatory food intake, the findings show. Type 1 diabetes is an autoimmune disorder characterised by the destruction of insulin-producing β-cells in the pancreas, necessitating lifelong ...

Effective therapies needed to halt rise in eco-anxiety, says psychology professor

2025-07-01
More must be done to address the growth in anxiety related to climate change, says a leading psychologist, before it becomes the next mental health crisis. In his book Understanding Climate Anxiety, Geoff Beattie documents how climate anxiety is on the rise, especially amongst young people. Yet support is limited and sufferers face stigma because of the polarised debate around whether the climate crisis even exists, he says. Understanding Climate Anxiety offers psychological tips and guidance ...

Nature-friendly farming boosts biodiversity and yields but may require new subsidies

2025-07-01
Farming methods that support nature improve both biodiversity and crop yields but more extensive measures may require increased government subsidies to become as profitable as conventional intensive agriculture. That is the finding of the first comprehensive on-farm trials of their kind in the UK, which were led by the UK Centre for Ecology & Hydrology (UKCEH) and Rothamsted Research. This four-year study across 17 conventional, commercial farms in southern England not only trialled various agroecological methods but also – for the first time – the financial viability for businesses. It showed that incorporating nature-friendly practices within farming – agroecology ...

Researchers Saul Estrin (London School of Economics), Tomasz Mickiewicz (Aston University), and Peng Zhang (University of Sheffield) analyzed survey data from over 3,000 informal entrepreneurs across eight African countries. They explored how pre-colonial family structures—especially the practice of marrying within the extended family—affect ...

Novel flu vaccine adjuvant improves protection against influenza viruses, study finds

2025-07-01
ATLANTA — Influenza hemagglutinin subunit vaccines are more effective and offer better cross protection against various influenza virus challenges when combined with a mucosal adjuvant that enhances the body’s immune response, according to a study by researchers in the Institute for Biomedical Sciences at Georgia State University. The study published in the journal ACS Nano shows that immune cell-derived extracellular vesicles, specifically those from mature bone marrow-derived dendritic cells (which are crucial for immune responses), rather than those from immature dendritic cells, are potent mucosal adjuvants for influenza hemagglutinin vaccines. The influenza hemagglutinin ...

Manipulation of light at the nanoscale helps advance biosensing

2025-07-01
Traditional medical tests often require clinical samples to be sent off-site for analysis in a time-intensive and expensive process. Point-of-care diagnostics are instead low cost, easy-to-use, and rapid tests performed at the site of patient care. Recently, researchers at the Carl R. Woese Institute for Genomic Biology reported new and optimized techniques to develop better biosensors for the early detection of disease biomarkers. People have long been fascinated with iridescence of peacock feathers, appearing to change color as light hits them from different angles. With ...
