Escalating global carbon dioxide (CO) emissions have significantly exacerbated the climate impact, necessitating imperative advancements in CO-capture technology. Liquid absorbents have received considerable attention in carbon capture for engineering applications, due to their high flexibility, reliability, and recyclability. Nonetheless, the existing technologies of liquid CO capture suffer from various issues that cannot be ignored, such as corrosion, elevated costs, and pronounced secondary pollution.

Methods: Distinguished expression of FCGBP mRNA in HNSCC was analyzed by TCGA-HNSC and three GEO datasets, the relationship between FCGBP and clinical stage and survival was analyzed by GEPIA 2, the immune infiltration pattern analysis was conducted by TIMER 2.
Background: It is unknown whether acral melanomas (AMs) associated with pre-existing nevi have similar risk to other AMs.
Objective: To compare risk of recurrence and death between AMs associated with pre-existing nevi and de novo AMs.
Methods: We conducted a multicenter retrospective cohort study involving patients diagnosed with AMs between February 2011 and November 2022.
Macrocyclic peptides have garnered significant attention as promising drug candidates. However, they typically face challenges in achieving and enhancing cell permeability for access to intracellular targets. In this study, we focused on the screening of macrocyclic peptide inhibitors against the main protease (Mpro) of SARS-CoV-2 and identified novel noncovalently bound macrocyclic peptides that effectively inhibit proteolytic activity.

Their structures were determined by nuclear magnetic resonance (NMR) data, single-crystal X-ray diffraction (XRD) analyses, and electronic circular dichroism (ECD) comparisons. Bioactivity evaluation showed that compound 9 considerably inhibited T cell proliferation in vitro with an IC value of 5.
