Medical Xpress / Wearable polygraph tracks hidden stress through five body signals in real time
Northwestern University engineers have developed a small, wireless polygraph system you can wear. Unlike polygraphs used in television crime dramas, this wearable version isn't optimized to detect lies. Instead, engineers ...
Medical Xpress / New rules for used prosthetic feet could curb 'medical equipment graveyards'
Researchers have proposed new standards into the decades-old prosthetic donations market, improving the quality of lower limb prosthetic feet by two-thirds—a major quality of life boost for recipients.
Medical Xpress / 15-year quest yields malaria compound that hits parasite at all major stages
A Portland State University-led research team has developed a novel chemical compound that shows promise for the treatment and prevention of malaria, one of the world's deadliest diseases. Malaria, a mosquito-borne infectious ...
Medical Xpress / Immune protein emerges as possible target to slow Parkinson's progression
Monoclonal antibodies can block a key immune-related protein that drives the spread of brain cell damage in Parkinson's disease (PD). This protein, called glycoprotein nonmetastatic melanoma B (GPNMB), might be part of a ...
Medical Xpress / Post-exercise 'warm glow' increases generosity, study shows
You've just finished a workout, lungs burning, heart pumping, and you feel energized and ready to take on the day. That's your brain rewarding you with a hit of dopamine—the feel-good hormone that exercise is known to trigger.
Medical Xpress / Fear memories fade faster when brain immune cells engage key neurons, study suggests
Post-traumatic stress disorder (PTSD) and anxiety disorders are often characterized by fearful responses in specific situations that the mind learns to view as threatening. These fearful responses typically emerge following ...
Medical Xpress / Future cancer therapy could use immunity to clean up damaged DNA by modulating AUF1
Researchers have identified a pathway that triggers an immune response in cells with defective DNA repair. In particular, the authors of a new paper demonstrated how the downregulation of AUF1 impairs DNA repair, followed ...
Medical Xpress / It's not just deep sleep: Anesthesia drives brain into a strange state doctors are only beginning to map
People often describe anesthesia as something that puts a patient in a "deep sleep." An anesthesiologist enters the operating room, and part of their mission is to ensure that the patient is completely unaware of what is ...
Medical Xpress / Cannabis and tobacco co-use increases psychosis chances in high-risk cohorts, study shows
A new multisite study published in Nature Mental Health found that using cannabis and tobacco together increases the risk of developing psychotic disorders like schizophrenia among those considered high risk.
Medical Xpress / Too little sleep—and too much—associated with faster aging
An analysis of biological clocks throughout the human body suggests that too few hours of sleep—and too many—may speed aging in the brain, heart, lung, and immune system and is associated with a wide range of diseases.
Medical Xpress / Non-coding gene is linked to core social and behavioral traits in autism
A long-overlooked stretch of the human genome appears to play a distinct role in shaping the social and stereotypic repetitive behaviors that define autism spectrum disorder (ASD), without affecting learning or other cognitive ...
Medical Xpress / Urine nanosensor tracks lung cancer signals and early fibrosis, moving toward clinical trials
A urine test developed by scientists at the University of Cambridge has moved a step closer to clinical use following new findings revealing it could do more than first thought. Originally designed to detect early signs of ...
