Preparation and properties of guanidine-based antimicrobial ultra-high molecular weight polyethylene fiber for uranium extraction from seawater

Fushe yanjiu yu fushe gongyi xuebao
Fiber absorbents are among the most economical materials for uranium extraction from seawater. Marine organisms are prone to fouling while being deployed in the sea, severely impairing the adsorption properties of the fiber.

Genetic variants underlying precancerous conditions of hepatocellular carcinoma

International Journal of Cancer, Volume 158, Issue 3, Page 488-502, 1 February 2026.
Abstract Hepatocellular carcinoma (HCC) is the most common form of liver cancer, accounting for 80% of cases worldwide. While chronic hepatitis B and C infections remain primary risk factors, emerging evidence highlights the increasing contributions of metabolic dysfunction‐associated steatotic liver disease (MASLD) and alcohol‐associated liver disease
