Food Science &Nutrition, Volume 14, Issue 7, July 2026.Dietary polyphenols and phytochemicals suppress NF‐κB signaling. Mechanistically, by inhibiting IκBα degradation and preventing nuclear translocation of p65/p50 complexes, the polyphenols reduce the expression of pro‐inflammatory and pro‐survival genes, thereby decreasing overall cancer cell survival.

Journal of Mass Spectrometry, Volume 61, Issue 7, July 2026.ABSTRACT Genome sequencing is the gold standard for microbial identification. However, it fails to distinguish closely related species with overlapping genetic features. This is the case of Bacillus cereus and Bacillus cytotoxicus, two members of the B. cereus group with distinct pathogenic profiles. While B. cereus, a well‐known opportunistic pathogen
