Early childhood caries (ECC)—the world's most prevalent chronic childhood disease—disproportionately targets specific teeth, a mystery that has remained unresolved until now.
Medical Xpress / AI helps researchers understand lung disease and proposes treatment
The secrets of idiopathic pulmonary fibrosis (IPF) are written in its very name. Idiopathic refers to a disease of unknown cause, and the condition, which turns healthy lung tissue into fibrous scar tissue, still raises many ...
Medical Xpress / Repeated exposure to wildfires can incrementally increase heart failure risk
Long-term exposure to wildfire smoke may increase the risk of heart failure (HF), especially in older adults, women and vulnerable populations, according to a study published in the Journal of the American College of Cardiology ...
Medical Xpress / Antibiotics and energy inhibitors effectively kill aggressive melanoma cells by blocking mitochondrial pathways
Researchers have discovered that the most aggressive melanomas, the deadliest form of skin cancer, overactivate two key processes in mitochondria, the components of cells that provide energy. Blocking these pathways with ...
Medical Xpress / Novel therapy saves patient with severe heart inflammation
Acute myocarditis—sudden inflammation of the heart—causes mild symptoms in most cases, but about 10% of acute myocarditis cases can be sudden and severe, leading to cardiac arrhythmias, heart pump failure, or even death. ...
