Medical Xpress / Healthy aging shaped by more varied biology than previously thought
Molecular changes in aging are far more unique than previously thought, meaning two healthy individuals of identical age can experience significantly different aging journeys.
Medical Xpress / Cancer medication helps reduce SIV reservoir, increasing hope for HIV cure
Emory University researchers have provided the first proof of concept in a nonhuman primate model for eliminating HIV-infected cells with venetoclax, a clinically approved cancer medication. Venetoclax effectively targets ...
Medical Xpress / Key path to Alzheimer's-like brain damage starts outside the brain
Immune cells that normally protect the body from damage by attacking foreign or infected cells are found in the brains of patients with Alzheimer's disease and related disorders at much higher levels than in healthy brains. ...
Medical Xpress / How the developing human brain takes instructions: Two studies reveal what guides its most important stem cells
As the human brain takes shape before birth, a remarkable type of stem cell helps give it many of the features that make it distinctly human. These cells, called radial glia, make billions of decisions that determine which ...
Medical Xpress / How meal timing programs the liver's daily rhythms
Deep inside the brain, a master clock synchronizes thousands of molecular clocks scattered throughout the body, and together, they anticipate signals such as the rising sun, the coming night and the daily rhythms of life. ...
Medical Xpress / Microdroplets may reduce colorectal tumor growth at potentially lower cost
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed microscopic peptide droplets that deliver large amounts of gene-silencing molecules into cancer and immune cells, reducing the growth ...
Medical Xpress / Three psychedelic drugs affect the brain differently, brain scans in rats suggest
In recent years, psychedelic drugs have attracted growing interest as potential treatments for conditions including depression, anxiety and addiction. Although these drugs are often considered one group, researchers from ...
Medical Xpress / C. difficile colonization in infants reshapes gut development, challenging a long-held assumption
Since its discovery, the highly contagious bacterium Clostridioides difficile (C. difficile or C. diff) has been reported not to cause symptoms in infants, leading to the assumption that colonization was not a serious health ...
Medical Xpress / Cerebral palsy might be a collection of symptoms, not its own disease
Historically, cerebral palsy (CP) was linked largely to events at birth, including prematurity or temporary loss of oxygen to the brain, but research over the past decade has suggested that genetic factors contribute to CP ...
Medical Xpress / Stopping chronic pain before it starts: Surprising biological pathway may play key role
Chronic pain is one of medicine's most stubborn puzzles. A sprained back, a surgical incision or a pinched nerve heals—and yet, for millions of people, the pain never fully goes away. Why some injuries fade into memory while ...
Medical Xpress / Routine clinical data help AI predict rapid Parkinson's decline three to five years in advance
For patients diagnosed with Parkinson's disease, one of the greatest uncertainties is what comes next. Some people experience relatively mild symptoms for years. Others face a much steeper course marked by worsening movement ...
Medical Xpress / Neural networks reveal how experience shapes learning in both brains and machines
A new study has used a type of machine learning called a neural network to reveal how different kinds of training can change how learning happens—both in machines and in living brains.
