Adsorption and Potential CO Gas-Sensing Performance of the Fe-Doped TiCO-MXenes: A First-Principles Study.

The adsorption behaviors and electronic properties of five gas molecules (CO, HO, NH, NO, and CHO) on the intrinsic TiCO and Fe-doped TiCO were calculated and studied based on first principles. The adsorption height, bond length change, adsorption energy, charge transfer, band structure, differential charge, work function, and recovery time of the two gas adsorption systems were discussed, and their sensing performance was evaluated. The results show that the CO gas molecules have the best adsorption energy and charge transfer on TiCO modified by the Fe atom (TiCO-Fe).

Dual action of macrophage miR-204 confines cyclosporine A-induced atherosclerosis.

Background And Purpose: Atherosclerosis induced by cyclosporine A (CsA), an inhibitor of the calcineurin/nuclear factor of activated T cells (NFAT) pathway, is a major concern after organ transplantation. However, the atherosclerotic mechanisms of CsA remain obscure. We previously demonstrated that calcineurin/NFAT signalling inhibition contributes to atherogenesis via suppressing microRNA-204 (miR-204) transcription.

Potential mouse models of coronavirus-related immune injury.

Basic research for prevention and treatment of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues worldwide. In particular, multiple newly reported cases of autoimmune-related diseases after COVID-19 require further research on coronavirus-related immune injury. However, owing to the strong infectivity of SARS-CoV-2 and the high mortality rate, it is difficult to perform relevant research in humans.
