Medical Xpress / New imaging combines light and sound to watch brain oxygen supply in real time
The brain is a black box of densely packed neurons, blood vessels and immune cells, all locked away in a sealed skull. WashU's Song Hu has dedicated his career to unlocking that puzzle box by developing new ways to "see" ...
Medical Xpress / Highly potent compound that blocks Ebola virus entry discovered
A University of Minnesota–led multi-institutional research team has discovered a highly potent small molecule that blocks Ebola virus entry by stabilizing the virus's entry protein and provides strong protection when given ...
Medical Xpress / Tiny astrocyte sensors in the brain's fear center point to a potential target for anxiety and depression
A new study led by UCLA Health researchers has identified a specific type of brain cell and a tiny structure on its surface that changes when the body is under stress, which may help explain why stress can lead to anxiety ...
Medical Xpress / Targeted antibody treatment reverses diabetic nerve damage in mouse models
A team of UTHealth Houston researchers slowed and even reversed diabetic nerve damage in mice, bringing researchers one step closer to developing a treatment for humans. The research is published in Science Translational ...
Medical Xpress / Calorie restriction reveals a potential way to slow age-related DNA mutations
Mutations are changes in the molecular "letters" that make up DNA, the genetic blueprint for cells. Mutations build up with age in every cell when DNA is damaged or when cells make mistakes in fixing or copying it. Most mutations ...
Medical Xpress / Brain's rhythm signals may help memory circuits communicate
A new study by researchers at the University of California, Irvine, suggests that slow electrical rhythms traveling along individual nerve fibers may do more than reflect brain activity: They may help coordinate communication ...
Medical Xpress / Blood protein analysis could help diagnose rare diseases missed by genome sequencing
Researchers from Queen Mary University of London, the Berlin Institute of Health at Charité (BIH) and Genomics England have shown that measuring proteins in the blood can provide important additional clues about the effects ...
Medical Xpress / Nasal spray protects neurons and memory in Alzheimer's mouse model
A nasal spray containing vesicles naturally released by cells may work against Alzheimer's. This is the promise of a study conducted by researchers at the Università Cattolica, Fondazione Policlinico Universitario A. Gemelli ...
Medical Xpress / A microscopic obstacle course hints at how disorder may prime tumor cells for invasion
In 2024, malignant tumors caused more than 21,300 deaths in Austria, 4.7% more than in 2014. Faced with a similarly pressing global challenge, scientists are striving to better understand what drives cancer cells to grow, ...
Medical Xpress / Anemia in pregnancy linked to differences in babies' brain development
Researchers using a portable MRI scanner found that measurable differences in brain volumes emerged at around 12 months of age, offering some of the earliest evidence yet that maternal anemia shapes infant brain development ...
Medical Xpress / Certain DNA signatures may reveal which prostate cancers are most likely to spread
Prostate cancer is the second most common form of cancer among men globally. Yet, we still know relatively little about why the disease develops or why some men live with it for years while it progresses aggressively in others.
Medical Xpress / High anxiety may alter the brain's sleep switch in preteens
Some preteens have no trouble getting a full night's rest. Those experiencing anxiety often lie awake. The reason for both may be related to a pea-sized gland in the middle of their brains.
