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 / 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 / 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 / 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 / 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 ...
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 / Home-based chemotherapy: Pilot study demonstrates safety and feasibility
In a study published in NEJM Catalyst, Mayo Clinic researchers demonstrate that chemotherapy can be safely delivered in patients' homes. The study evaluated Mayo Clinic's Cancer CARE Beyond Walls (Connected Access and Remote ...
Medical Xpress / Engineered tissue offers hope for children born with 'missing' esophagus
Scientists from Great Ormond Street Hospital (GOSH) and University College London (UCL) have created the first lab‑grown esophagus—the food pipe—shown to safely replace a full section of the organ and restore normal ...
Medical Xpress / From pathology image to biological discovery: LazySlide uses foundation models to connect tissue images and RNA data
Microscopic images of human tissue are a cornerstone of biomedical research and clinical diagnostics. Yet despite their importance, these images often remain difficult to analyze systematically and to connect with other types ...
Medical Xpress / Digital decision support tool proven to reduce risks in bowel surgery
Recent research provides robust evidence for the use of a digital visualization and decision support tool in colorectal (bowel) surgery. This is the first time that a digital decision support tool has been conclusively proven ...
Medical Xpress / Large imaging study changes understanding of the origins of Parkinson's rest tremor
A Finnish clinical imaging study shows that rest tremor in Parkinson's disease is not explained by greater dopamine loss. In contrast, tremor appears to be associated with relatively better-preserved dopamine function. Researchers ...
