Abstract Etoposide (ETO) is a commonly used chemotherapeutic drug that inhibits topoisomerase II activity, thereby leading to genotoxicity and cytotoxicity. However, ETO has limited application due its side effects on normal organs, especially the kidney. Here, we report mechanism of ETO-induced cytotoxicity progression in human kidney proximal tubule (HK-2) cells. Our results show perpetuates DNA damage, activates mitogen-activated protein kinase (MAPK), triggers morphological changes, such...

We experimentally demonstrated that heat-dissipation power driven by ferromagnetic resonance (FMR) in superparamagnetic nanoparticles of ferrimagnetic MFe2O4 (M = Fe, Mn, Ni) gives rise to highly localized incrementation targeted temperatures. The generated thereby is extremely high: two orders magnitude higher than the conventional Néel-Brownian model. From micromagnetic simulation and analytical derivation, we found robust correlations between temperature increment intrinsic material...

In genetic hybrids, nucleolus formation on chromosomes inherited from only one parent is the epigenetic phenomenon, nucleolar dominance.
