Medical Xpress / Lab-grown nerves match human sensory signal speeds, enabling tests of myelin repair
Rice University and collaborators in Switzerland have developed a platform to grow human-derived nerve cells and Schwann cells, supporting cells that form a protective coating called myelin around nerve fibers. This platform ...
Medical Xpress / LDL-cholesterol lowering medication linked to lower mortality in high-risk patients
Mass General Brigham Heart and Vascular Institute researchers have found that high-risk patients who had not previously experienced a heart attack or stroke had a lower risk of death after taking the cholesterol-lowering ...
Medical Xpress / T cell therapy shows promise in treating aggressive brain cancer
A new phase 1 clinical trial has found that an emerging immunotherapy is promising for treating recurrent glioblastoma, a highly aggressive and fatal brain cancer. Chimeric antigen receptor T (CAR-T) cell therapy is a form ...
Medical Xpress / Computer vision 'sees' our organs age at different rates
We tend to think of age as a linear progression marked by birthdays and milestones dictating when we can vote, drink, rent a car or pass beyond the crest of an arbitrary metaphorical hill. When scientists look at how organs ...
Medical Xpress / Scientists uncover microbiome signaling system that could open new paths for IBS-related constipation
Mayo Clinic researchers have discovered that chemical signals produced by gut bacteria work together to control intestinal movement. One bacterial signal helps set the intestines in motion, while another primes gut cells ...
Medical Xpress / Breast density laws linked to higher ultrasound use after mammography
More than 40% of American women ages 40 and older have dense breast tissue, according to the National Cancer Institute. This type of tissue can make cancer harder to spot on mammograms and is itself associated with a higher ...
Medical Xpress / A 'one-two punch' against aggressive breast cancer could offer an alternative to chemotherapy
Triple-negative breast cancer (TNBC) has a frustrating ability to adapt. Although this aggressive form of breast cancer can initially respond well to chemotherapy, cancer cells often find ways to survive, allowing the disease ...
Medical Xpress / Tumor 'floor plans' may predict immunotherapy response better than current biomarkers
Spatial transcriptomics is a powerful tool for creating a detailed map of not just how genes are expressed in a piece of tissue, but also where genetic activity takes place in different cells and locations within the tissue. ...
Medical Xpress / Evidence often falls short in neuroscience reports of sex-dependent effects, analysis finds
Studies in the behavioral and brain sciences reporting a major sex-dependent effect—that a drug, treatment or other intervention is more effective in one sex than another—are supported by appropriate evidence less than 25% ...
Medical Xpress / Each breath is linked to brain activity, offering clues to epilepsy-related breathing failures
A new study led by researchers at the University of California San Diego shows that the brain does not simply respond to breathing as a steady rhythm. Instead, the detailed shape of each individual breath is closely linked ...
Medical Xpress / Cancer's malignant remote control: How tumors reprogram liver fat metabolism to disarm immune cells
In their quest to understand how cancers take root, grow and spread, scientists have for the past half-century explored the genetic aberrations and microenvironmental peculiarities of tumors and their constituent cells. Such ...
Medical Xpress / Potent antiplatelet drugs increase major bleeding risk in AF patients after heart attack
Potent antiplatelet therapy increased bleeding without signs of benefit regarding cardiovascular events in patients with atrial fibrillation after a heart attack. This was the main finding of the EPIDAURUS trial presented ...
