https://phys.org/ en-us Latest news from Hanyang University According to recent reports from the Korean government, the incidence of alcoholic liver disease—previously the leading indication for liver transplantation—has been decreasing. This trend initially raised expectations that the medical burden of liver transplantation and liver-related mortality would decline. However, the current reality does not reflect this expectation. In addition, fatty liver disease is also increasing steadily due to modern lifestyle factors, and projections indicate that the demand for liver transplantation will continue to rise, with fatty liver-related cases increasingly replacing those caused by alcoholic liver disease. https://medicalxpress.com/news/2026-02-key-mechanism-fatty-liver-disease.html Oncology & Cancer Mon, 16 Feb 2026 22:00:01 EST news690455578 Power transmission lines (TLs) are ubiquitous, spanning diverse landscapes, including forests, agricultural regions, as well as mountains.
