Medical Xpress / Microplastics turn up in nearly every human brain sample, including healthy tissue
Tiny micro- and nanoplastic fragments seem to be turning up everywhere, including one of the most well-protected parts of the human body—the brain. In a recent study conducted by Chinese researchers, they found microplastics ...
Medical Xpress / From gut to brain: Scientists engineer bacteria to treat severe liver-related brain dysfunction
When the liver fails, toxins—such as ammonia—that should be filtered from the blood build up and reach the brain. The result is hepatic encephalopathy (HE), a devastating neurological complication of liver disease that can ...
Medical Xpress / Cellular pathways may underlie some differences in physical fitness
Patterns of molecular activity in the blood may hold clues not only to how fit someone is, but also to the biological processes that support physical performance. Researchers at MIT, GE HealthCare, and the U.S. Military Academy ...
Medical Xpress / Excessive cholesterol in astrocytes linked to cognitive decline in Alzheimer's mice
Alzheimer's disease (AD) is a neurodegenerative disorder that leads to progressive memory loss and a decline in mental functions. Several past studies have linked this disease to the accumulation of the protein amyloid-β ...
Medical Xpress / Age, sex, and cancer type can influence risk of subsequent cancers among survivors
The risk of developing a subsequent primary cancer varied significantly by age at initial diagnosis, sex, and type of first cancer, according to a study by Oxana Palesh and Susan Hong and colleagues at Virginia Commonwealth ...
Medical Xpress / Experimental drug may restore movement after stroke
Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to lose function and die over the following days—has remained one of the most important unanswered ...
Medical Xpress / How the immune system battles lifelong viral infections acquired at birth
Millions of people worldwide carry viral infections they acquired at birth, often for life. For a long time it was assumed that the immune system hardly fights these pathogens. Researchers from the University of Basel show ...
Medical Xpress / Fluorescent quail embryos could help solve serious birth defects in humans
The quail is a small, unassuming bird that glides rather than flies and prefers to hide under bushes than to perch on top of a tree. And now, it's also helping scientists understand serious birth defects in humans.
Medical Xpress / Adversity across life linked to greater frailty and faster biological aging
Published in BMC Medicine, the study analyzed data from over 150,000 participants and found the strongest associations in people who experienced adversity in both childhood and adulthood. These individuals were more frail ...
Medical Xpress / Cancer cells can rewrite RNA messages, creating new drug targets in aggressive tumors
Scientists have uncovered an unexpected way cells can generate cancer-driving proteins—by cutting RNA into shorter, functional fragments rather than following the standard blueprint. This process, newly termed as "RNA dicing," ...
Medical Xpress / AI model detects normally 'invisible' tissue changes of pancreatic cancer at stage 0
An AI model (REDMOD) can pick up the very early subtle tissue changes of pancreatic ductal adenocarcinoma, the most common form of pancreatic cancer, which conventional imaging and the human eye find difficult to detect, ...
Medical Xpress / Scientists create first-ever 'smell map' of the nose's smell receptors
For most of us, the sense of smell is an integral part of everyday life; it plays a critical role in providing information about our surroundings, alerting us to potential dangers, enhancing our sense of taste, and evoking ...
