Medical Xpress / Local neural wiring may set the brain's range of activity patterns
The human brain contains billions of neurons, specialized nerve cells that receive, transmit and process information through electrical and chemical signals. Human thoughts, sensory perceptions and behaviors are known to ...
Medical Xpress / Aging blocks the retina's ability to regrow lost neurons, a first-of-its-kind study finds
A new study from the laboratory of Levi Todd, Ph.D., at Upstate Medical University has found that aging significantly limits the ability of support cells in the retina, called glia, to be reprogrammed into new neurons, a ...
Medical Xpress / Energy-hungry tissues expand cleanup crews to clear worn-out mitochondria
The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture) and brown fat (for heat production) each require a lot of energy and make a lot of waste. That waste needs to be managed.
Medical Xpress / Early mitochondrial stress reveals potential mechanism for lasting heart protection
Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do much more—including acting as signaling hubs. Some signals that mitochondria send can reprogram the activity of the entire ...
Medical Xpress / Cancer drug tames atherosclerosis inflammation and plaque in animal models
A new Yale study has identified a promising therapeutic avenue for atherosclerosis, a condition caused by inflammation and plaque buildup in arteries. Martin Schwartz, Ph.D., Robert W. Berliner Professor of Medicine (Cardiology) ...
Medical Xpress / Rethinking radiotherapy may boost immunotherapy for pancreatic cancer
Pancreatic cancer remains one of the most aggressive malignancies, with a particularly poor prognosis even when diagnosed at a localized stage. In a paper published in Nature Reviews Gastroenterology & Hepatology, researchers ...
Medical Xpress / CRISPR gene-editing therapy safely and continuously lowers cholesterol and triglycerides, first-in-human trial shows
A Cleveland Clinic first-in-human clinical trial has shown that a one-time infusion of a gene-editing therapy using CRISPR-Cas9 was effective and safe in reducing LDL ("bad") cholesterol and triglycerides in people with medication-resistant ...
Medical Xpress / AI may help identify breast cancers missed by mammograms, but clinical benefit remains uncertain
Artificial intelligence may help radiologists identify subtle signs of breast cancers that are missed during routine mammograms, and some AI systems may even identify patterns associated with an increased risk of cancer before ...
Medical Xpress / Gut-derived bacterial molecule may drive severe liver disease
Researchers at the University of Oslo and Oslo University Hospital, together with international collaborators, have discovered that a small molecule made exclusively by gut bacteria can actively drive disease in the bile ...
Medical Xpress / New blood biomarkers reveal how common muscular dystrophy treatment may impair overall growth
In a study published in Scientific Reports, an international, multidisciplinary research team that included Binghamton University researchers identified a set of blood proteins that may explain why the corticosteroid prednisone, ...
Medical Xpress / Experimental brain implants are on the rise. What happens after the trials are over?
In 2024, Elon Musk's Neuralink put its first brain implant into a human amid doubt from scientists and allegations of animal cruelty.
Medical Xpress / Voice disorder may be an early sign of dementia, study suggests
Those experiencing worsening voice quality—in pitch, clarity, volume, reduced vocal range or other voice disorders—and no hearing loss may be at 58% greater risk of cognitive impairment or dementia than those who are not ...
