Medical Xpress / Microplastics in human liver could be fueling global surge in disease
There is considerable evidence that microplastics and nanoplastics are present in the livers of humans, and wild animal populations on land and in the ocean. Now experts in environmental and human health are investigating ...
Medical Xpress / How a chemical reaction triggers brain inflammation in Alzheimer's disease
The brain has its own immune system, which detects threats and mounts a defense. A growing body of evidence has shown that in Alzheimer's disease, those immune cells are chronically overactivated, causing inflammation that ...
Medical Xpress / Scientists transform wool into bone repair material
Scientists have shown how wool could offer an effective and sustainable alternative to materials currently used to repair damaged bone. In the new study, keratin—a natural structural protein derived from wool—was shown to ...
Medical Xpress / Hidden in hair follicles, immune 'sentinel' cells may help skin detect microbes
Researchers at the School of Medicine at the University of California, Riverside have discovered previously unrecognized immune surveillance structures in the skin. Found within hair follicles, the cells resemble M (microfold) ...
Medical Xpress / HIV disrupts lung 'clock,' raising COPD and emphysema risk
People living with HIV face a greater risk of developing lung diseases at a much younger age, even if they have never smoked. FIU researchers have now uncovered a previously unknown mechanism that helps explain how HIV causes ...
