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 / 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 / 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 / A banned chemical still lingers, and its strangest effect may depend on sex, genes and one common vitamin
In two new studies, researchers at the UC Davis MIND Institute have clarified how a long-banned group of chemicals, called polychlorinated biphenyls (PCBs), affect genetic activity. The research helps explain how biological ...
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 / 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 / Macaques reveal human-like genetic cause of inherited blindness, offering new disease model
An inherited form of blindness directly comparable to a common inherited optic nerve disease in humans has been discovered in rhesus macaques at the California National Primate Research Center at the University of California, ...
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 / Smart soft sensors restore surgeons' sense of touch in minimally invasive procedures
Researchers at NYU Abu Dhabi have developed soft, flexible sensors that help restore a surgeon's sense of touch during minimally invasive (keyhole) surgery. These procedures allow for faster recovery and less pain, but surgeons ...
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 / How bones make marrow: Newly identified 'organizer' cells also reappear after fractures
Bone marrow is the spongy tissue located within the hollow center of bones, serving as the primary site for the continuous production of red blood cells, platelets, and white blood cells. Despite its physiological importance, ...
Medical Xpress / Digital twin can reveal alcohol consumption in crime cases
Using a so-called digital twin, it is possible to predict with greater precision than at present how much alcohol a person has consumed and at what time. The study was conducted by researchers at Linköping University and ...
