Medical Xpress / Miniaturized bone marrow-on-a-chip tracks human immune cells as they build lasting antibody defenses
A scientific team has developed a laboratory model that reveals how antibody-producing plasma cells migrate, mature and survive within human bone marrow, a main location of long-lived antibody-producing plasma cells. The ...
Medical Xpress / Scientists uncover why some Huntington's disease patients decline years earlier
A new study has revealed why some people with Huntington's disease develop symptoms 10–12 years earlier and experience a more aggressive form of the disease.
Medical Xpress / New insights into how the brain responds after a severed nerve is repaired could boost recovery
We carry a map of our bodies around in our brains. It's not a literal picture, but an organized pattern of brain activity. So, touch different fingers and different parts of the brain respond. Remarkably, this arrangement ...
Medical Xpress / Smartphone-controlled microneedle patch could offer drug-free pain care from afar
A "wearable electroceutical" has been developed that could reduce the need to visit a hospital or rely on painkillers every time pain occurs. When attached to the skin, it modulates pain through electrical stimulation and ...
Medical Xpress / Blocking gene boosts T-cell attacks on chronic hepatitis B virus and tumors
A research team led by Professor Zhou Xuyu from the Institute of Microbiology of the Chinese Academy of Sciences (CAS), in collaboration with researchers from Beijing Ditan Hospital and Capital Medical University, has identified ...
Medical Xpress / Newly found dendrite bottlenecks may reshape how neurons handle information
Neurons receive thousands of signals via tree-like extensions called dendrites. Until now, these dendrites were thought to be relatively smooth cables that conduct electrical signals to the cell body. An international research ...
Medical Xpress / Brain-computer interface enables avatar speech and gestures for people with paralysis
A scientific team has shown that a new brain-computer interface (BCI) can allow people with vocal tract and bodily paralysis to convey both speech and upper-body gestures simultaneously. While BCIs have facilitated one or ...
Medical Xpress / Engineered vesicles protect brain from bacterial toxin
Bacterial meningitis can cause severe brain damage even when patients receive antibiotic treatment promptly. Researchers at Karolinska Institutet have developed tiny biological vesicles that, in animal studies, were able ...
Medical Xpress / Metabolic vulnerability identified that may affect heart development
The heart undergoes major changes during the first weeks of life. Researchers at Karolinska Institutet have now shown that a previously unknown metabolic vulnerability in mitochondria can disrupt heart development. The study, ...
Medical Xpress / Fine-tuning medical AI can improve diagnosis but also creates privacy risks
Qingyu Chen, PhD, and his team set out to study how artificial intelligence language models are adapted for medicine and found that what these models memorize can be both useful and risky. A model may retain valuable medical ...
Medical Xpress / Bacteria in the airway may shape air pollution health risk
Air pollution is linked to different risks of bacterial pneumonia, sepsis and meningitis, depending on the bacterial subtype a person carries, new research suggests.
Medical Xpress / Magnetic pulses reprogram immune cells to fight breast cancer in preclinical models
Researchers from the National University of Singapore (NUS) have demonstrated an innovative approach for targeted breast cancer therapy using pulsed electromagnetic fields (PEMFs). The NUS team successfully reprogrammed tumor-associated ...
