Medical Xpress / Scientists discover hidden gateways that allow the brain to clear waste
The brain continuously produces metabolic waste that must be removed to maintain healthy function. Cerebrospinal fluid (CSF) plays a central role in this process by carrying away proteins such as amyloid-β, phosphorylated ...
Medical Xpress / Exceptional memory in 80s defies simple Alzheimer's genetic risk explanation
Many people assume that some memory decline is an inevitable consequence of getting older. But a select group of older adults, known as "SuperAgers," reach their 80s and 90s while retaining memory performance as good as or ...
Medical Xpress / Gut immune cells may help explain how B-cell depletion controls MS
B-cell depletion therapies, in which B cells of the immune system that may drive disease activity in multiple sclerosis (MS) are temporarily removed, have contributed significantly to improved treatment for patients in recent ...
Medical Xpress / The lone star tick is bringing another infection concern, the Bourbon virus
Tick-borne diseases are common throughout the United States, and most cases are treated effectively. A rarely diagnosed tick-borne infection, the Bourbon virus, transmitted by the common lone star tick, could soon begin to ...
Medical Xpress / Breathalyzer can 'sniff out' when your body starts burning fat
Researchers have developed a breath detector with a chemical sensor that sniffs out when your body is burning fat through a single exhale. Reporting in Device, the handheld, smartphone-assisted device measures acetone—a ...
Medical Xpress / Three genetic modifiers may alter inherited Alzheimer's onset and progression
Autosomal dominant Alzheimer's disease (ADAD) is a genetically inherited form of Alzheimer's disease that accounts for only about 1% of Alzheimer's disease cases. However, because individuals with the gene mutations are extremely ...
Medical Xpress / New tool uncovers overlooked disease-linked genes by accounting for ancestry and family ties
Every person's DNA tells a unique story. To unlock the full potential of genetic research, scientists need tools that reflect the complexity of the people they study.
Medical Xpress / Brain-penetrating nanoparticles, ultrasound and microbubbles show promise in treating glioblastoma
University of Virginia Comprehensive Cancer Center scientists have developed a promising new experimental approach to targeting glioblastoma, the most common and deadliest brain cancer. The approach could overcome many of ...
Medical Xpress / How a pandemic detour helped researchers uncover clues to a mysterious disease
When the COVID-19 pandemic shut down international travel in 2020, Michigan State University researcher Eric Benbow faced a problem. A $2.5 million research project designed to study an environmental pathogen in South America ...
Medical Xpress / Dendrites and gatekeeper cells unlock flexible learning in mice, study finds
The ability to adapt behavior flexibly to changing environments is a hallmark of intelligence. However, the biological mechanisms in the brain that are responsible for this cognitive flexibility remain poorly understood.
Medical Xpress / Singing therapy provides symptom relief and greater quality-of-life for people with chronic belching
A new randomized clinical trial suggests that singing therapy may provide a more effective and engaging treatment option than standard breathing exercises for people with supragastric belching, a chronic gastrointestinal ...
Medical Xpress / Same carcinogen, different tumors: Mouse study reveals the role of genetic background
Why do cancers develop differently in different people—even when they are exposed to the same risk factors? An international research group, including the German Cancer Research Center (DKFZ), has demonstrated in mice that ...
