Medical Xpress / Largest study of pregnancy sickness uncovers six new genetic links
The USC research team that recently identified the hormone-encoding gene GDF15 as a key driver of pregnancy sickness has identified nine additional genes linked to its most severe form, hyperemesis gravidarum (HG). Six of ...
Medical Xpress / New drug doubles 1-year survival in pancreatic cancer trial
Pancreatic cancer is one of the deadliest cancers and among the hardest to treat, with most patients surviving less than a year after diagnosis. But a new drug developed at Northwestern University may soon help patients live ...
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 / Blood test can predict Alzheimer's disease progression years before symptoms or brain scan changes
A study by investigators at Mass General Brigham has found that a blood test of plasma phosphorylated tau 217 (pTau217), an Alzheimer's disease biomarker, can predict the progression of amyloid PET scan changes and cognitive ...
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 / Loneliness hits memory early, but it doesn't speed brain decline
Loneliness affects the memory of older adults but does not speed up mental decline over time, suggests data from a major European study tracking more than 10,000 people over seven years. Participants who reported high levels ...
Medical Xpress / Chloride ions do more than help neurons fire—they may also help control how genes are expressed
Chloride ions, best known for helping cells maintain fluid balance and electrical stability, may also play a more direct role in regulating brain development than previously thought. In a new study, published in the journal ...
Medical Xpress / Neuroinflammation triggers autism-like regression in mouse model
Autism spectrum disorder (ASD) is a neurodevelopmental condition estimated to affect approximately 1 in 100 children worldwide. This condition is characterized by differences in how people communicate and interact with others, ...
Medical Xpress / Low-frequency wireless sensor tracks artery stiffening in real time with less interference
Wireless sensors used in wearable smart devices and medical equipment must be capable of detecting minute changes while maintaining high operational stability. However, existing technologies often utilize excessively high ...
Medical Xpress / Fluoride and kids' IQ: What a decades-long analysis shows
Fluoride is a naturally occurring mineral that has been shown to strengthen teeth and reduce cavities. Many municipalities add fluoride to their drinking water—a process called community water fluoridation—as a public health ...
Medical Xpress / APOE4, the Alzheimer's risk gene, silently undermines bone quality in women
Scientists at the Buck Institute for Research on Aging, along with collaborators at UC San Francisco, have discovered that APOE4, the most common genetic risk factor for Alzheimer's disease, causes bone quality deficits specifically ...
Medical Xpress / Pain-sensing neurons mapped in unprecedented detail, pointing to new chronic pain drug targets
One in five people worldwide suffers from chronic inflammatory pain. Meanwhile, about two thirds of those affected find little relief from existing pain medications; new therapeutic approaches are urgently needed. "We first ...
