Moral licensing, a phenomenon where initial moral behavior can lead to later immoral behavior, challenges the sustainability of moral behavior over short-term periods. In the framework of moral self-regulation, current research examined the inhibitory effects of high moral identity and moral elevation on moral licensing. Across three studies we consistently found that recalling past moral behavior can trigger moral licensing (Study 1, 2, 3).

Three chondroitin sulfate (CS) analogues with predominant subtypes (A, C, and E) were prepared from engineered K4 combined with regioselective sulfation. CS with the designed sulfates as the main components was characterized by nuclear magnetic resonance spectroscopy, elementary analysis, and disaccharide analysis. CS prepared from the native or degraded capsular polysaccharide had molecular weights of 1.

A novel series of azo dyes was successfully synthesized by combining amino benzoic acid and amino phenol on the same molecular framework azo linkage. The structural elucidation of these dyes was carried out using various spectroscopic techniques, including UV-vis, FT-IR, NMR spectroscopy, and HRMS. Surprisingly, the aromatic proton in some dyes exhibited exchangeability in DO, prompting a 2D NMR analysis to confirm this phenomenon.

Ectopic lipid deposition in the hepatocyte plays an important role in the development of nonalcoholic fatty liver disease (NAFLD), which has become one of the most common causes of chronic liver disease worldwide yet no approved drugs are currently available. In this study, a cell-based method was developed to screen potential drugs with low toxicity that inhibit lipid accumulation. In the same 96-well plate, cytotoxicity was measured using CCK8 assay, followed by lipid content detection using BODIPY 493/503 via fluorometry assay, a lipid droplet-specific fluorescent dye commonly used in microscopy and flow cytometry, but not previously reported in fluorometry.

Bacteriocin lactococcin036019 was identified and characterized from Lactococcus lactis NCU036019, which displayed significant antibacterial activity toward foodborne pathogenic bacteria Staphylococcus aureus under various conditions. However, the in situ low-level expression of lactococcin036019 severely limited its wide application in food industry. In this study, we optimized the medium ingredients and culture conditions of L.
