Medical Xpress / Human liver tissue cell architecture reconstructed in 3D at a cellular level
Never-before-seen 3D reconstructions of human liver tissue have been created at a cellular level. The details obtained by a team of UW Medicine and University of Washington engineers and physicians capture the spatial microstructure ...
Medical Xpress / Natural compound from pomegranate leaves disrupts disease-causing amyloid
A research team at Kumamoto University has discovered that a natural compound found in pomegranate leaves and branches can directly break down harmful protein aggregates linked to transthyretin (TTR) amyloidosis, a progressive ...
Medical Xpress / New strategy grabs cancer's 'undruggable' proteins and throws them in the cellular trash
When cancer-driving proteins resist various treatments, Northwestern University scientists have uncovered a new solution. Don't fight them—throw them in the cellular trash. In a new study published in Nature Communications, ...
Medical Xpress / Novel markers of brain blood flow and oxygenation may offer early clues to Alzheimer's risk
Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's disease risk, according to new research from the Mark and Mary Stevens Neuroimaging and Informatics ...
Medical Xpress / It's not just about the number on the scale: The hidden value of so-called 'yo-yo dieting'
So-called "yo-yo dieting" confers long-term health benefits, according to a new study by Ben-Gurion University of the Negev researchers. "Yo-yo dieting" is a pattern in which individuals lose weight through lifestyle interventions ...
Medical Xpress / ChatGPT Health: First independent evaluation raises safety questions
ChatGPT Health, a widely used consumer artificial intelligence (AI) tool that provides health guidance directly to the public—including advice about how urgently to seek medical care—may fail to direct users appropriately ...
Medical Xpress / The brain's primitive 'fear center' is actually a sophisticated mediator, research reveals
A Dartmouth study challenges the conventional view that the amygdala—the two-sided structure deep in the brain involved in emotion, learning, and decision making—is simply the brain's primitive "fear center," reflexively ...
Medical Xpress / As worms and jellyfish wriggle, new AI tools track their neurons
Understanding the connection between behavior and brain cell activity is a major goal of neuroscience. To make progress, neuroscientists often choose simple, transparent lab animals because it's possible to see all their ...
Medical Xpress / Engineered immune therapy could help fight brain aging
Researchers with the Knight Initiative for Brain Resilience have modified a well-known immune protein to spark the growth of new neurons, ease brain inflammation, and improve cognition in old mice. The findings, published ...
Medical Xpress / Stimulating mitochondria to boost long-term memory
An international team led by Jaime de Juan-Sanz at the Paris Brain Institute has shown that slightly increasing the metabolic capacity of neurons can enhance long-term memory in both fruit flies and mice. The study, published ...
Medical Xpress / Centenarians' blood sheds light on the mechanisms of longevity
In Switzerland, 0.02% of the population lives beyond the age of 100. Could there be biological characteristics associated with this exceptional longevity? As part of the "SWISS100" study, the first large-scale Swiss research ...
Medical Xpress / Did you hear about the lab-made ear?
In laboratory experiments, researchers have produced ear cartilage that remains form-stable in animal models. Only one element is missing to make the tissue as elastic as a natural ear.
