Medical Xpress / Many head and neck cancer trials end early. Why?
Head and neck cancer trials are frequently derailed before they can deliver answers. A new analysis suggests that the most common reasons are sponsor decisions related to safety or effectiveness and poor patient recruitment.
Medical Xpress / Whole-genome sequencing may optimize PARP inhibitor use for cancer patients
A whole-genome sequencing approach shows early promise over current commercial methods for identifying more patients likely to benefit from PARP inhibitor cancer treatments, according to a study led by Weill Cornell Medicine ...
Medical Xpress / Axonal protein synthesis defect identified as potential early driver in ALS progression
Researchers at VIB and KU Leuven have identified a molecular process that allows motor neurons to maintain protein production, a process that fails in amyotrophic lateral sclerosis (ALS). The study, published in Nature Neuroscience, ...
Medical Xpress / Uncovering how occludin protein maintains blood-brain and blood-retinal barriers
The blood-brain and blood-retinal barriers are protective systems that prevent harmful substances from entering the brain and eyes. These barriers are created by cells that are joined tightly together by proteins. Dysfunctional ...
Medical Xpress / Toddlers in England spending two hours on screens a day, doubling recommended screen time

Medical Xpress / Intraoperative tumor histology may enable more-effective cancer surgeries
The first line of treatment for cancer is, whenever possible, to remove the cancerous tissue from the body. Though often remarkably effective, removing only the cancerous tissue is a challenge for doctors and surgeons. With ...
Medical Xpress / New brain study explains how binge drinking contributes to long-lasting negative feelings
New research has identified that neuroinflammation driven by microglia (immune cells in the brain) is a primary underlying driver of prolonged negative feelings caused by repeated, sustained binge drinking (binge exposure). ...
Medical Xpress / Why leaving things unfinished messes with your mind
There's a personal story that Yale psychologist Brian Scholl often shares when he explains his scholarly interest in the vexing power of what he calls "unfinishedness," or that nagging frustration you experience when tasks ...
Medical Xpress / Microbially produced secondary bile acids accelerate colorectal cancer development, study shows
For the first time, a team of experts from the Technical University of Munich (TUM), RWTH Aachen University, and the German Institute of Human Nutrition Potsdam-Rehbruecke (DIfE) has demonstrated the causal role of microbially ...
Medical Xpress / How aggressive breast cancer controls protein production
A previously unknown mechanism that makes it possible for aggressive so-called triple-negative breast cancer to fine-tune its production of proteins has been discovered by researchers at Umeå University, Sweden. The discovery ...
Medical Xpress / AI-driven insurance decisions raise concerns about human oversight
As health insurers increasingly turn to AI, researchers explore the promise of efficiency—and the risk of amplifying existing flaws.
Medical Xpress / Like alcohol units, but for cannabis—experts define safer limits
Researchers at the University of Bath in the UK are proposing thresholds for safe—or at least safer—cannabis use and hope their findings will help people monitor consumption and keep it within recommended limits—similar ...
