Medical Xpress / AI tool reveals rare cancer cells tied to faster disease progression
McGill University researchers have developed an artificial intelligence tool that can identify small groups of cells most responsible for driving aggressive cancers. The tool, called SIDISH, offers scientists a clearer path ...
Medical Xpress / For women with primary progressive MS, could bestselling drug be doing more harm than good?
The US Food and Drug Administration (FDA) is reviewing a petition to revoke the approval of Roche's top-selling drug ocrelizumab (Ocrevus) for treating primary progressive multiple sclerosis (PPMS)—a form of MS thought to ...
Medical Xpress / What raises vaccination rates most? Access, community outreach and incentives lead the list
Extending vaccination opportunities, involving community members alongside health care professionals in communicating about vaccines, and providing financial incentives are among the most effective ways to increase vaccine ...
Medical Xpress / 3D brain tumor organoids provide new scientific opportunities for research community
Efforts to identify and evaluate next-generation therapeutics for pediatric brain tumors are easily stymied by the quality and availability of laboratory models for research. To address this issue, scientists at St. Jude ...
Medical Xpress / How a misdirected DNA alarm could reshape treatment for rare rapid-aging diseases
The human immune system is finely tuned to detect and destroy viral threats. But this same defense system can misfire. When fragments of the body's own damaged DNA are mistaken for viral invaders, the result is a powerful, ...
Medical Xpress / Quality versus quantity of fat in the diet affects development of diabetes
A new study examines the role of palmitic acid and oleic acid—among the main fatty acids in the diet—in the development of type 2 diabetes mellitus, a chronic condition associated with high morbidity and mortality worldwide. ...
Medical Xpress / New method advances efforts to overcome bias in AI tool for children with anxiety
Researchers at Cincinnati Children's, working with collaborators at University College London and Oak Ridge National Laboratory, have identified a practical, data-centered strategy to reduce bias in artificial intelligence ...
Medical Xpress / Why psychedelic mental health trials may be less reliable than they appear
Drug trials generally involve comparing a treatment with a nonactive, placebo version, an approach called "blinding" because patients must be "blind" as to which they've received for the trial to work. Canadian researchers ...
Medical Xpress / As syphilis cases rise, study links infection with higher risk of stroke, heart attack and other serious problems
Syphilis has been rising sharply in the United States, with especially high rates in Southern states. Now, a new study from Tulane University researchers suggests the long-term infection may carry another risk that is often ...
Medical Xpress / Ultra-processed food intake tied to sharply higher obesity risk in adolescents
Adolescents who consume more ultra-processed foods (UPFs) have significantly higher odds of being overweight or obese, according to a new systematic review and meta-analysis published in the open-access journal PLOS One by ...
Medical Xpress / RNA sequencing platform unlocks rare disease diagnoses missed by standard tests
Researchers from Children's Hospital of Philadelphia (CHOP) developed a new RNA sequencing strategy that can reveal how genetic variants disrupt gene function and improve the diagnosis of rare diseases.
Medical Xpress / A powerful new cancer map tracks hundreds of mutations to one escape route and exposes a drug target
Diseases like cancer or neurodegeneration are known to arise from genetic misfires. But treating such complex conditions hasn't been simply a matter of identifying the malfunctioning genes involved. With hundreds of genetic ...
