Scientists reveal mechanism that causes irritable bowel syndrome

KU Leuven researchers have identified the biological mechanism that explains why some people experience abdominal pain when they eat certain foods. The finding paves the way for more efficient treatment of irritable bowel ...

Neuroscience

Study suggests compound protects myelin, nerve fibers

A compound developed at Oregon Health & Science University appears to protect nerve fibers and the fatty sheath, called myelin, that covers nerve cells in the brain and spinal cord.

Scientists reverse deadly impacts of asthma in mice

Mucus in the lungs can be fatal for asthma patients, but scientists at the University of Colorado Anschutz Medical Campus have broken up those secretions at the molecular level and reversed their often deadly impacts.

Immunology

Lipid biomarkers in urine can determine the type of asthma

In a new study, researchers at Karolinska Institutet in Sweden have used a urine test to identify and verify a patient's type of asthma. The study, which has been published in the American Journal of Respiratory and Critical ...
