CREG1 attenuates intervertebral disc degeneration by alleviating nucleus pulposus cell pyroptosis via the PINK1/Parkin-related mitophagy pathway.

Intervertebral disc degeneration (IVDD) is a chronic degenerative disease with a complex pathophysiological mechanism. Increasing evidence suggests that the NOD-like receptor thermal protein domain associated protein 3 (NLRP3)-mediated pyroptosis of nucleus pulposus cells (NPCs) plays a crucial role in the pathological progression of IVDD. Pyroptosis is a novel form of programmed cell death characterized by the formation of plasma membrane pores by gasdermin family proteins, leading to cell swelling, membrane rupture, and the release of inflammatory cytokines, which trigger an inflammatory response.

Silicon Carbide Nanowire Based Integrated Electrode for High Temperature Supercapacitors.

Silicon carbide (SiC) single crystals have great prospects for high-temperature energy storage due to their robust structural stability, ultrahigh power output, and superior temperature stability. However, energy density is an essential challenge for SiC-based devices. Herein, a facile two-step strategy is proposed for the large-scale synthesis of a unique architecture of SiC nanowires incorporating MnO for enhanced supercapacitors (SCs), arising from the synergy effect between the SiC nanowires as a highly conductive skeleton and the MnO with numerous active sites.
