Aim: To evaluate the diagnostic accuracy of microbiome-derived biomarkers for periodontitis in oral fluids (saliva and subgingival samples).
Methods: This systematic review followed PRISMA guidelines. Electronic searches were performed across multiple databases from December 2022 to November 2024.
Article Synopsis
- - The study examines three types of hydrogen bonds in glycine and water complexes around metal ions, specifically focusing on interactions involving the NH and oxygen groups attached to a metal ion or the α-carbonyl oxygen.
- - Different metal complexes of glycine (like cobalt, nickel, and copper) were analyzed using advanced computational methods to understand the nature and strength of these hydrogen bonds.
- - Results indicate that electrostatic interactions are the strongest attractive force in these complexes, with complex charge having the most significant impact on the energy decomposition of the interactions, while other factors like metal oxidation and atomic number play a lesser role.
Article Synopsis
- * Hydrogen sulfide is a flexible molecule, able to change its bond angle and length with only a minor energy increase, and exhibits a variation in the bond angle (H-S-H) of 15.6° and bond lengths (S-H) of 0.082 Å without affecting the strength of its hydrogen bonds.
- * The analysis
Periodontitis is associated with an increased risk of ischemic stroke, and the risk may be particularly high among young people with unexplained stroke etiology. Thus, we investigated in a case-control study whether periodontitis or recent invasive dental treatments are associated with young-onset cryptogenic ischemic stroke (CIS). We enrolled participants from a multicenter case-control SECRETO study including adults aged 18 to 49 y presenting with an imaging-positive first-ever CIS and stroke-free age- and sex-matched controls.

The data reveal the existence of antiparallel interactions in crystal structures and significant interaction energies. Data from the CSD for alcohol-alcohol dimers show 49.
