Safety of laparoscopic graspers with different configurations during liver tissue clamping
Biosurface and Biotribology, 2018 Laparoscopic graspers often induce liver damage when large forces are applied during clamping. Here, the safety of graspers with different edge curvature radii, teeth profiles, and jaw windows was evaluated experimentally using a tissue damage assessment

Advanced Functional Materials, EarlyView.Tumor‐tropic human mesenchymal stem cells (hMSCs) were used as delivery vehicles for magnetotheranostic gold–iron oxide nanoflowers. Magnetic particle imaging of the iron component demonstrated widespread intratumoral distribution and sustained retention in contrast to injection of naked nanoflowers.
