Red blood cells exposed to oxygen deficiency protect against myocardial infarction, according to a new KI study published in the Journal of Clinical Investigation. The study also shows that the protective effect is enhanced by a nitrate-rich vegetable diet.

Red blood cells carry oxygen from the lungs to all of the body’s cells and carbon dioxide back to the lungs. A new study, conducted at Karolinska Institutet in collaboration with Karolinska University Hospital, now shows that red blood cells have an intrinsic function of protecting against heart injury caused by myocardial infarction.

The effect is enhanced by a diet containing nitrate-rich vegetables, such as arugula and other green l...

Catastrophic forgetting, an innate issue with backpropagation learning algorithms, is a challenging problem in artificial and spiking neural network (ANN and SNN) research.

The brain has somewhat solved this problem using multiscale plasticity. Under global regulation through specific pathways, neuromodulators are dispersed to target brain regions, where both synaptic and neuronal plasticity are modulated by neuromodulators locally. Specifically, neuromodulators modify the capacity and property of neuronal and synaptic plasticity. This modification is known as metaplasticity.

A novel study from the University of South Australia has identified a range of metabolic biomarkers that could help predict the risk of cancer.

Deploying machine learning to examine data from 459,169 participants in the UK Biobank, the study identified 84 features that could signal increased cancer risk.

Several markers also signalled chronic kidney or liver disease, highlighting the significance of exploring the underlying pathogenic mechanisms of these diseases for their potential connections with cancer.

The study, “Hypothesis-free discovery of novel cancer predictors using machine learning,” was conducted by UniSA researchers: Dr Iqbal Madakkatel, Dr Amanda Lumsden, Dr Anwar Mulugeta, and Professor Elina Hyppönen, with University of Adelaide’s Professor Ian Olver.

“We...
