Medical Xpress / New Huntington target may open simpler drug path to slow brain damage
Huntington disease is a rare, inherited brain disorder that progressively destroys nerve cells, leading to worsening movement, cognitive and psychiatric symptoms. Caused by a mutation in the huntingtin gene, the fatal disease ...
Medical Xpress / New map reveals how antidepressants reshape the brain's serotonin system
A new study has uncovered how antidepressants affect different groups of serotonin-producing brain cells in opposite ways, offering new insights into why selective serotonin reuptake inhibitors (SSRIs) can cause unpleasant ...
Medical Xpress / Researchers trigger sleep's restorative effect in parts of the awake brain
By inducing specific patterns of activity in small portions of the brain in awake mice, researchers have triggered a recalibration of neural connections that normally only occurs during sleep. This new approach offset the ...
Medical Xpress / Study shows US tobacco firms used cigarette-selling tactics to globally market ultra-processed foods
A new study from the University of Kansas details how U.S. tobacco corporations expanded into global food markets from the mid-1980s to the mid-2000s, using strategies honed through cigarette sales to market ultra-processed ...
Medical Xpress / Metabolic switch in lung cancer reprograms immune cells to slow tumors
An international research team, led by Justus Liebig University Giessen (JLU), the Institute for Lung Health (ILH) in Giessen, and the Max Planck Institute for Heart and Lung Research in Bad Nauheim, has identified a promising ...
Medical Xpress / New evidence offers hope for ketogenic therapy in treatment of anorexia nervosa
A pilot study published today in Communications Medicine demonstrates the potential of a new approach to treating anorexia nervosa, a disorder for which effective treatments have been significantly limited. The research from ...
Medical Xpress / Mylpf protein serves as a molecular linchpin for muscle health
University of Maine researchers have published new findings about how muscles form, why certain muscle diseases develop and why symptoms may not appear until years after muscle degeneration begins.
Medical Xpress / Left-handed DNA tubes double cancer drug killing by boosting cell uptake
Researchers in the lab of Cancer Center at Illinois (CCIL) member Xing Wang have discovered the influential role of structural chirality, or "handedness," of a DNA nanostructure to dictate cancer cell response to targeted ...
Medical Xpress / AI can reveal brain tumor risks without costly genetic testing
Mayo Clinic researchers and collaborators have shown that artificial intelligence (AI) can analyze routine pathology slides to help classify meningiomas, the most common primary brain tumor in adults, and predict a patient's ...
Medical Xpress / Shiga-producing E. coli infections becoming more resistant to antibiotics, study finds
Resistance to antimicrobial agents is rising among human infections with Escherichia coli bacteria that produce the Shiga toxin, according to a study analyzing data from nearly 2,000 infections in the United States between ...
Medical Xpress / Testing AI against public health's existing tools shows mixed results
A new Penn-led randomized controlled trial has found that AI-powered chatbots can make vaccine-hesitant parents more likely to say they will immunize their children against human papillomavirus (HPV), but no more than standard ...
Medical Xpress / Tiny protein tail helps one immune gene fight two very different viruses
Our genomes contain hundreds of genes with antiviral jobs that are called into action when a virus succeeds in infecting one of our cells. By acting cooperatively, these genes provide defense against a wide range of viruses, ...
