An exploratory metabolomic study reveals the Dipsacus asper-Achyranthes bidentate herb pair against osteoarthritis by modulating imbalance in polyunsaturated fatty acids and energy metabolism.

Osteoarthritis (OA) is a degenerative joint disease primarily affecting the cartilage. The therapeutic potential of the Dipsacus asper-Achyranthes bidentate herb pair for OA has been acknowledged, yet its precise mechanism remains elusive. In this study, we conducted a comprehensive analysis of metabolomic changes and therapeutic outcomes in osteoarthritic rats, employing a gas chromatography-mass spectrometry-based metabolomics approach in conjunction with histopathological and biochemical assessments.

HKUST-1 Derived Hollow C-Cu S Nanotube/g-C N Composites for Visible-Light CO Photoreduction with H O Vapor.

As the main component of syngas, reducing CO to CO with high selectivity through photocatalysis could provide a sustainable way to alleviate energy shortage issues. Developing a photocatalytic system with low cost and high performance that is environmentally friendly is the ultimate goal towards CO photoreduction. Herein, an efficient and economic three-component heterojunction photocatalyst is designed and fabricated for converting CO to CO in the absence of organic sacrificial agents.

Photoreduction of carbon dioxide under visible light by ultra-small Ag nanoparticles doped into Co-ZIF-9.

Metal-organic frameworks (MOFs) are well-known porous materials able to adsorb CO, and their performance in CO reduction has attracted much attention from researchers. A classical Co-MOF, Co-ZIF-9, has been proposed as a novel photocatalyst for reducing CO into chemical feedstocks. Herein, Co-ZIF-9 with a rod-like structure was obtained through reflux.
