Medical Xpress / Long before adulthood, a chemical mark may quietly shape how the brain handles stress
Stress or trauma during childhood may leave people more vulnerable to mental health struggles and stress later in life. Scientists think one reason could be that early-life stress leaves lasting molecular bookmarks on DNA, ...
Medical Xpress / Scientists uncover cellular mechanism driving both rare childhood dementia and Alzheimer's disease
Researchers at the University of California San Diego and their colleagues have identified a key cellular pathway that drives brain degeneration in both a rare childhood disorder and the far more common Alzheimer's disease. ...
Medical Xpress / Cell-surface receptors guide antisense therapy to mutant KRAS in pancreatic cancer cells
Antisense oligonucleotides (ASOs) have been proposed as a therapeutic approach to shut down the production of faulty proteins in a wide variety of diseases, including cancer. In a study published in the Journal of Cell Biology ...
Medical Xpress / Stem cells create humanlike heart valve tissue to model disease and test treatments
Melbourne researchers have created human heart valve tissues from stem cells, providing a powerful new platform to advance treatments for childhood heart diseases.
Medical Xpress / Wearable microneedle patch empowers conventional ultrasound for continuous glucose monitoring
Long-term diabetes management requires continuous blood glucose monitoring to detect abnormalities early and intervene in time. However, conventional fingertip blood sampling is both painful and inconvenient, while most continuous ...
Medical Xpress / Thyroid's two hormone-producing cell types develop separately before merging, study finds
The thyroid gland consists of two types of hormone-producing cells that regulate the body's metabolism and calcium balance. In mammals, these cell types merge into a single organ, whereas in other vertebrates, they develop ...
Medical Xpress / Sleep could help identify people at risk of developing Alzheimer's disease at an earlier stage
What if certain signs of the disease were to manifest subtly during sleep, long before the first memory problems appear? This is the line of inquiry being explored by a team of researchers at ULiège.
Medical Xpress / A free, continuously updated guide to bipolar disorder treatments
The most comprehensive review to date has identified the most effective bipolar disorder treatments across different age groups and mood phases. It was published in The BMJ.
Medical Xpress / ACL injuries may get an early-warning system through AI and wearable sensors
As a sophomore wide receiver who had just joined the USF football team, Jaden Alexis didn't expect a routine play to turn into a career-defining moment. During preseason football camp, Alexis had just sprinted up the sideline ...
Medical Xpress / A broader panel of protein markers could lead to better blood tests for Alzheimer's
In Alzheimer's disease, amyloid plaques form in the brain, followed by threadlike structures made of the protein tau. Both changes have toxic effects on the brain's nerve cells years before dementia symptoms appear. Historically, ...
Medical Xpress / Genetic variants shed light on kidney transplant rejection
Immunosuppressive medications help prevent organ rejection following transplantation, yet some patients still experience rejection despite receiving adequate treatment. New research from Yale, published in the Journal of ...
Medical Xpress / Heart assembloids give researchers a new way to study heart valve disorders
A multidisciplinary, multi-institution group of researchers focused their expertise in genetics, mechanics, chemistry and biology on a chip the size of a postage stamp to model a particular class of heart conditions.
