In this review, the major pigments found in fruits and their extraction and stabilization techniques for uses as food additives will be looked over.Aim To explore the biological functions and clinicopathologic significance of the long noncoding RNA KTN1-AS1 in head and neck squamous cell carcinoma (HNSCC). Materials & methods We assessed the effects of KTN1-AS1 and identified the target miRNA by bioinformatics analysis, luciferase reporter, RNA pull-down and RNA immunoprecipitation assays. The clinicopathologic features of KTN1-AS1 and its target miRNA were analyzed in HNSCC. Results KTN1-AS1, a competing endogenous RNA, promoted cell proliferation, migration, invasion and epithelial-mesenchymal transition by sponging miR-153-3p in HNSCC. Dysregulation of SNAI1 and ZEB2 mediated the effect of KTN1-AS1 due to miR-153-3p exhaustion. The KTN1-AS1 and miR-153-3p combination can accurately diagnose HNSCC. Conclusion The KTN1-AS1 and miR-153-3p combination could be a valuable diagnostic and prognostic predictor for HNSCC.Charge-enhanced Brønsted acid organocatalysts with electron-withdrawing substituents were synthesized, and their relative acidities were characterized by computations, 11 binding equilibrium constants (K11) with a UV-vis active sensor, 31P NMR shifts upon coordination with triethylphosphine oxide, and in one case by infrared spectroscopy. Pseudo-first-order rate constants were determined for the Friedel-Crafts alkylations of N-methylindole with trans-β-nitrostyrene and 2,2,2-trifluoroacetophenone and the Diels-Alder reaction of cyclopentadiene with methyl vinyl ketone. These results along with kinetic isotope effect determinations revealed that the rate-determining step in the Friedel-Crafts transformations can shift from carbon-carbon bond formation to proton transfer to the catalyst's conjugat
