Alterations in brain metabolites in rats with experimental periodontitis: A metabolomic approach
Journal of Periodontology, EarlyView.Abstract Background Periodontitis (PD) is a chronic inflammatory disease with systemic effects. Emerging evidence suggests a link between periodontal inflammation and neurological changes, but the biochemical mechanisms in key brain regions, such as the hippocampus and amygdala, remain unclear.

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level
Journal of Raman Spectroscopy, EarlyView.Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security
Journal of the Science of Food and Agriculture, EarlyView.Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Macromolecular Rapid Communications, EarlyView.We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...
