Medical Xpress / Hidden switch lets two of four receptor subunits open brain ion channel
To transmit excitatory signals, nerve cells mostly use glutamate as a neurotransmitter. To detect these transmitter signals, the cells can rely on a whole repertoire of receptors with different signaling properties. Researchers ...
Medical Xpress / Boosting protein folding could protect insulin-making cells in diabetes
Origami masters turn simple sheets of paper into ornate sculptures. In the origami of life, our cells must fold proteins into specific three-dimensional shapes before they can carry out their biological jobs. This folding ...
Medical Xpress / Why glioblastoma keeps beating treatment: Hidden signaling axis could open new drug path
An international study led by a scientist at the University of Ottawa Faculty of Medicine is opening new frontiers in the fight against glioblastoma (GB), a devastating cancer behind the most malignant and treatment-resistant ...
Medical Xpress / Laxative drug could ease depression-related brain fog, early trial suggests
People with depression who find that it affects their memory or attention span could benefit from an existing licensed drug currently used to treat chronic constipation.
Medical Xpress / Why some newborn flies sleep instead of eat: Gut blockage offers clues to brain-gut signals
The gut does much more than just digest food. Researchers at the University of Basel have discovered a surprising link between gut function, feeding and sleep in fruit flies. Their study adds to growing evidence that the ...
Medical Xpress / Integrating genetic origin data with tumor analyses enables better prediction of survival
New research to be presented today at the annual conference of the European Society of Human Genetics shows that a cancer patient's genetic ancestry can have a significant effect both on how their disease progresses and their ...
Medical Xpress / Mosquito nets remain a powerful weapon against malaria—but research warns their long-term effectiveness is under threat
A major analysis of 25 studies across Africa and Asia finds that insecticide-treated nets cut malaria cases by up to 68%—but highlights challenges that threaten to undermine their long-term impact.
Medical Xpress / Could a once-a-day pill replace weight loss injections? Phase II oral GLP-1 drug trial shows promising results
For those scared of needles but who need GLP-1 receptor agonists to help manage their weight, there might be some good news. Researchers are testing a new oral, small-molecule GLP-1 receptor agonist called Elecoglipron, which ...
Medical Xpress / Vitamin C levels in blood plasma linked with brain connectivity and volume in older adults
A study of 2,044 older Japanese adults found that those with lower vitamin C levels in their blood plasma tended to have a lower volume of gray matter in their brains, as well as lower connectivity among a collection of brain ...
Medical Xpress / Long-read DNA test lifts rare disease diagnoses and could replace 15 other tests
A new test provides a much more complete picture of DNA than current standard diagnostics and leads to a diagnosis more often. The test can replace 15 other tests, making it faster and more efficient. Researchers from Radboud ...
Medical Xpress / AI tool shown to reduce eye care disparities for African American adults with diabetes
In a study exploring how an AI-assisted diagnostic tool shaped care for underserved populations at multiple community-based primary care sites, investigators at the Wilmer Eye Institute, Johns Hopkins Medicine, found that ...
Medical Xpress / Sugar-coated CAR-T cells survive longer and shrink lymphoma tumors in mice
Scientists at Florida International University may have found a way to make a powerful cancer treatment work even better. The treatment, called CAR-T therapy, uses a patient's own immune cells to fight cancer. Doctors remove ...
