Medical Xpress / Smart wound dressing delivers antibiotics on-demand, accelerating healing and reducing resistance
Biomedical engineers from Brown University have developed a new wound dressing material that releases antibiotic drugs only when harmful bacteria are present in a wound. In the new study, published in the journal Science ...
Medical Xpress / Why some people naturally control HIV even after stopping therapy—and how we can leverage that to treat others
For millions of people living with HIV, a daily regimen of medications is a lifelong necessity. If they stop taking the drugs—commonly referred to as antiretroviral therapy—the virus usually rushes back within weeks. ...
Medical Xpress / An immune signaling pathway drives pain in arthritis, researchers discover
Rheumatoid arthritis is a chronic autoimmune disease that affects millions of people worldwide. This disease prompts the immune system to mistakenly attack body tissues, particularly joints, leading to inflammation, swelling, ...
Medical Xpress / AI-powered imaging tracks wound healing under the skin in real time
No matter the size or severity, wounds on human skin are difficult to monitor while they heal. Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could ...
Medical Xpress / Stress-activated pathway reveals how nervous system contributes to eczema flare-ups
The mystery of how stress exacerbates atopic dermatitis, more commonly known as eczema, may be closer to being understood. A new study published in the journal Science has identified a specific nerve pathway that helps explain ...
Medical Xpress / AI tool shows promise in diagnosing advanced heart failure
Applying artificial intelligence techniques to cardiac ultrasound data may make it easier to identify patients with advanced heart failure, a new study has found. The study—led by investigators at Weill Cornell Medicine, ...
Medical Xpress / Botox-like nerve blocking reveals potential way to fully regenerate skin without scarring
Could wounded skin someday regrow perfectly without scars? A new study by Harvard stem cell biologists published in Cell reveals a way to fully regenerate skin by unblocking an embryonic healing mechanism that shuts off after ...
Medical Xpress / Discovery of tiny cell 'tunnels' finds new path to slow Huntington's disease
Huntington's disease is a devastating brain disorder that slowly robs people of movement, memory, and personality. It is caused by a toxic protein that builds in brain cells and ultimately kills them. For years, scientists ...
Medical Xpress / 7-Tesla MRI machine uncovers new insights into PTSD
Powerful brain imaging has helped uncover why people with post-traumatic stress disorder (PTSD) who engage in negative self-talk may be struggling with the first line of treatment. The discovery, published in Nature Mental ...
Medical Xpress / Stability of brain's internal compass may help explain how memories last
A new discovery by McGill researchers sheds light on how we retain memories over time, even though brain activity is constantly changing. Published in Nature, the preclinical study found the brain's internal compass remains ...
Medical Xpress / Genes tied to impulse control play a major role in addiction risk
Most of the genetic risk for developing a substance use disorder comes from genes that broadly affect how our brains process rewards, regulate impulses and weigh consequences—not from genes that specifically influence substance ...
Medical Xpress / Deep learning model predicts how individual cells influence disease outcomes
A computational method called scSurv, developed by researchers at Institute of Science Tokyo, links individual cells to patient outcomes using widely available bulk RNA sequencing data. The approach uses single-cell reference ...
