Medical Xpress / A less invasive heart valve fix shows strong early results for older high-risk patients
A national study led by investigators from Cedars-Sinai Health Sciences University found that transcatheter tricuspid valve replacement, or TTVR, delivered strong early results in real-world practice. Patients treated with ...
Medical Xpress / Newly discovered neural connections in fruit flies reveal that inhibitory neurons can also drive movement
Researchers at UC Santa Barbara are coming ever closer to uncovering the neural circuitry that translates stimulus to action, shining light on previously unseen neural connections and lesser-known functions of neurons that ...
Medical Xpress / Unlocking secrets of human development: How early nerve cell choices shape the peripheral nervous system
Millions of neurons branch throughout our bodies, keeping them in close communication with our brains. This peripheral network begins to take shape long before birth, as the cells of a growing embryo move into position and ...
Medical Xpress / Base editing repairs mutation and liver function in mouse model of Zellweger spectrum disorder
In 2025, baby KJ Muldoon became the first person to receive a personalized gene editing treatment, which likely saved his life. But the scientific advances that made the groundbreaking treatment possible were years in the ...
Medical Xpress / New study identifies a key brain circuit for spatial memory in mice
A team led by the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and Miguel Hernández University of Elche (UMH), has identified a brain circuit essential for spatial memory. ...
Medical Xpress / Ultrasensitive test reveals evidence of previously undetected tuberculosis in hospital patients
Researchers at Boston University have discovered an unexpectedly high prevalence of Mycobacterium tuberculosis DNA (TB DNA) in patients hospitalized in Boston, suggesting that tuberculosis disease may be significantly underdiagnosed ...
Medical Xpress / Timing exercise to match body clock chronotype may lower cardiovascular disease risk
Timing exercise to match body clock chronotype—the natural predisposition to morning or evening alertness—may lower cardiovascular disease risk among those who are already vulnerable, suggests research published in the open ...
Medical Xpress / GLP-1 medicine improves liver health independent of weight loss, study finds
Researchers at Toronto's Sinai Health have found that semaglutide—the active ingredient in popular weight loss drugs that mimic the gut hormone GLP-1—acts directly on a subset of liver cells to improve organ function and ...
Medical Xpress / A new way to determine which patients will respond best to bowel cancer treatment
Nearly 10,000 cases of advanced bowel cancer are diagnosed in England each year, with cases in young adults rising. There are limited options for treating advanced bowel cancer. Scientists have now developed an AI-powered ...
Medical Xpress / How smell gets recognized so fast: Mouse brains appear to decide in the first 50 milliseconds
Mice make use of rapid nerve cell interactions in the brain's smell center to distinguish one odor from another, a new study shows. Both mice and humans can rapidly identify odors, researchers say, in a small fraction of ...
Medical Xpress / Taking a closer look at immune 'memory' could spur progress in the fight against lethal illnesses
The average human has about 1.8 trillion immune cells. These cells patrol the body for bacteria, viruses, cancers, and other threats. Vaccines enhance this security system by teaching our immune cells to target specific pathogens. ...
Medical Xpress / AI for early detection of self-harm behavior in psychiatric wards falters in real-world conditions, finds study
A research team led by Professor Hyun Ghang Jeong from the Department of Psychiatry at Korea University College of Medicine (Korea University Guro Hospital), in collaboration with the research team at Geovision Inc., has ...
