Medical Xpress / Protein-based MRI agent detects lung cancer and hidden metastases earlier than current scans
A multi-institutional research team led by Georgia State University Regents' Professor Emerita of Biochemistry and Biophysical Chemistry Jenny J. Yang has developed a new class of protein-based MRI contrast agents that detect ...
Medical Xpress / Psychedelics and anesthetics create mirror image patterns in the brain
For something so familiar to human experience, consciousness is still a mystery. Each day, people cycle through wakefulness and sleep, from a higher level of consciousness to a lower one. What's more, some people alter their ...
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 / 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 / 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 burst of 'pink noise' may lead to more restorative sleep
During the day, waste products such as lactic acid and worn-out proteins build up in the brain. When we sleep at night, waves of cerebrospinal fluid (CSF) help wash away this waste, keeping the brain healthy.
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 / Psychiatrists agree on a diagnosis in only 55% of cases, international study finds
In the 1970s, psychiatric diagnoses were marked by considerable uncertainty and disagreement. Since then, organizations such as the American Psychiatric Association and the World Health Organization (WHO) have worked to develop ...
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 / 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 / Clinical trial supports adding mental health care to routine preparation for major surgery
Facing major surgery is stressful, but for older adults, unaddressed anxiety and depression can impede physical recovery. A clinical trial led by researchers at Washington University School of Medicine in St. Louis found ...
