Medical Xpress / Blocking a mitochondrial transporter may curb inflammation from 'zombie' cells without killing them
Researchers have uncovered a previously unknown mechanism that helps aging cells drive the chronic inflammation linked to many age-related diseases. The findings reveal how dysfunctional mitochondria—the cell's energy-producing ...
Medical Xpress / Scientists develop microRNA-based gene therapy that halts ALS progression in mice
A single IV injection of a microRNA-based biologic developed by Guangping Gao, Ph.D., Robert H. Brown Jr., DPhil, MD, Jun Xie, Ph.D., and Zuoshang Xu, MD, Ph.D., suppressed production of the mutant SOD1 protein that causes ...
Medical Xpress / Bioceramic-coated implant improves osteoporotic fracture healing through timed magnesium release
Seoul National University (SNU) College of Engineering announced that a research team led by Nathaniel S. Hwang, a professor in the Department of Chemical and Biological Engineering, has developed a bioceramic fracture fixation ...
Medical Xpress / Gene editing tool reduces Huntington's toxic protein fragments and symptoms in mice
A gene-editing tool designed to precisely rewrite the gene that causes Huntington's disease reduced toxic protein fragments and symptoms associated with the disease in mice, researchers at the University of Illinois Urbana-Champaign ...
Medical Xpress / New mechanism reveals how heart cells resist regenerative reprogramming
Specialized cells in the human body make biological trade-offs to perform certain jobs. To support the large, hardworking hearts that power other organs, heart cells have evolved to be extremely efficient and resilient. Because ...
Medical Xpress / Climate change is redrawing the malaria map in Africa, study finds
Malaria is the deadliest climate-sensitive infectious disease. Yet researchers and public health officials have long argued over how climate change has shaped its spread. A new Nature study resolves this debate, providing ...
Medical Xpress / Two post-surgery blood–brain disruption windows may offer glioblastoma treatment targets
Scientists in Britain and Spain have discovered critical windows after glioblastoma surgery when the brain's defenses falter, creating a rare chance to deliver powerful treatments exactly where needed. If doctors time treatment ...
Medical Xpress / Support from animals may feel stronger for women and those spending more time with them
In a study of Swiss adults, women and people who spent more time with a pet or another animal to which they might feel close reported feeling more attached to the animal and receiving more socioemotional support from it. ...
Medical Xpress / Hidden 'recycling system' helps keep vision cells healthy
For decades, scientists believed that photoreceptors in the retina relied primarily on neighboring support cells, known as the retinal pigment epithelium (RPE), to remove waste. While the RPE is still responsible for clearing ...
Medical Xpress / Beyond recovery, natural environments may strengthen well-being from a neutral baseline
A walk in the park after a stressful day is a classic example of how nature can help people unwind. But natural environments may offer even more: enhancing mood and cognitive performance even when a person has not previously ...
Medical Xpress / Bloodstream-delivered cell therapy slows muscle decline in young people with Duchenne muscular dystrophy, trial finds
A cell therapy called deramiocel could slow muscle weakening in boys and young men with advanced Duchenne muscular dystrophy (DMD) and may also slow heart damage in those who already have heart muscle disease, a Phase III ...
Medical Xpress / Inflammation may drive Dravet syndrome, offering a potential new treatment target
An overactive immune response in the brain may play a role in Dravet syndrome, a rare and severe genetic epilepsy that typically begins in infancy, according to Weill Cornell Medicine researchers. Children with the condition ...
