Medical Xpress / Air pollution-linked blood changes detected years before lung cancer diagnosis
A new study, published Tuesday in Nature Communications, found measurable changes in people's blood associated with exposure to air pollution and the subsequent development of lung cancer. The findings provide promising clues ...
Medical Xpress / An origami-inspired implant could monitor health from beneath the skin
The skin is the body's largest organ. It is a protective shield that keeps harmful pathogens out and vital fluids inside. These very properties make it a tough engineering challenge to design wearable health sensors because ...
Medical Xpress / Protein secreted by immune cells may help drive brain aging
Brain-resident immune cells that have reached an old-age state called "senescence" secrete a protein that causes dysfunction in other brain cells, according to a study led by investigators at Weill Cornell Medicine. The discovery ...
Medical Xpress / How folic acid may protect a baby's developing brain and spinal cord
For more than 30 years, one piece of pregnancy advice has been remarkably consistent: Take folic acid. The reason is clear. Folic acid, or vitamin B9, can lower the risk of neural tube defects, serious birth defects that ...
Medical Xpress / Computational framework identifies novel pathway for asthma inflammation
Researchers at Columbia University Mailman School of Public Health, in collaboration with investigators at the University of Chicago, have developed a new computational framework that helps scientists identify genes that ...
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 / 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 / MRI model reveals microstructural brain changes linked to Huntington's disease
Researchers have shown that an imaging model can detect microstructural abnormalities in the brain associated with Huntington's disease, potentially offering a new method for monitoring disease progression and evaluating ...
Medical Xpress / Single-cell atlas reveals how spinal neurons help coordinate walking and other rhythmic movements
Scientists at St. Jude Children's Research Hospital created a single-cell atlas of a key class of spinal neurons involved in motor coordination. From that resource, they identified a small subgroup of interneurons associated ...
Medical Xpress / Cells' own abnormal RNA may trigger inflammation during viral infection, challenging 20 years of assumptions
New research led by the Hudson Institute of Medical Research has shown how a cell recognizes that it is infected with a virus to protect itself and surrounding cells or induce inflammation. The discovery, published in Nature ...
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.
