Metabolomic Evaluation of Chronic Periodontal Disease in Older Adults.

Periodontal disease is an infectious inflammatory disease related to the destruction of supporting tissues of the teeth, leading to a functional loss of the teeth. Inflammatory molecules present in the exudate are catalyzed and form different metabolites that can be identified and quantified. Thus, we evaluated the inflammatory exudate present in crevicular fluid to identify metabolic biological markers for diagnosing chronic periodontal disease in older adults.

New insights into the oral interactions of different families of phenolic compounds: Deepening the astringency mouthfeels.

Astringency is a tactile sensation of puckering, tightening and dryness in the oral cavity, commonly induced by polyphenols. In this study, the interaction of two phenolic compound mixtures, one rich in gallotannins and the other in flavonols, with two oral models (tongue (HSC3) or buccal mucosa (TR146) was evaluated. Results provided evidence that gallotannins and flavonols seem to bind in a different way to the different oral constituents and models used.

Potential Molecular Mechanisms of Rare Anti-Tumor Immune Response by SARS-CoV-2 in Isolated Cases of Lymphomas.

Recently, two cases of complete remission of classical Hodgkin lymphoma (cHL) and follicular lymphoma (FL) after SARS-CoV-2 infection were reported. However, the precise molecular mechanism of this rare event is yet to be understood. Here, we hypothesize a potential anti-tumor immune response of SARS-CoV-2 and based on a computational approach show that: (i) SARS-CoV-2 Spike-RBD may bind to the extracellular domains of CD15, CD27, CD45, and CD152 receptors of cHL or FL and may directly inhibit cell proliferation.
