Certain environmental toxins and chemotherapeutics are nucleic acid-damaging agents, causing adducts in DNA and RNA. While most of these adducts occur in RNA, the consequences of RNA damage are largely unexplored. Here, we demonstrate that nuclear RNA damage can result in loss of genome integrity in human cells.

Toward a better understanding of their hydride transfer reactivity, knowledge of the underlying thermodynamic hydricity values is deemed critical, but relevant studies remain rare. Herein, we report the experimental thermodynamic hydricity of a new ruthenium CO hydrogenation catalyst (PNP)RuH(CO)(PPh) () supported by a rigid, acridane-based PNP pincer ligand.

The effectiveness of traditional hepatocellular carcinoma treatments such as surgical resection, radiotherapy, and chemotherapy is limited, underscoring the need for innovative therapeutic strategies. To this end, we synthesized phthalyl-pullulan nanoparticles encapsulating IR780 (an NIR-responsive heptamethine cyanine dye) and R848 (resiquimod; a TLR7/8 agonist) (PIR NPs).

The stability of an IBC linked to a DC microgrid supplying a constant power load (CPL) can be imperceptibly guaranteed by a conventional controller. A tightly regulated CPL with nonlinear and negative incremental impedance characteristics will lead to stability issues.
