Posted: 02 Sep 2021 09:50 AM PDT

Periodontitis, a form of severe gum infection, can lead to tooth loss and is linked with other diseases. Management of periodontitis remains difficult, partly due to inadequate understanding of risk factors associated with the condition. In a recent study from Japan, researchers have emphasized the role of oral microbiome, over an individual's genetic makeup, in the development of the disease, providing clinicians a guide to designing strategies for diagnosing and treating periodontitis.

Knowledge of the detailed accumulation profiles of persistent organic pollutants (POPs) and POPs-like contaminants in wild animals is critical for ecological risk assessment. Comprehensive screening of organohalogen compounds in the livers of wild birds from Osaka, Japan using two-dimensional gas chromatography in combination with high resolution time-of-flight mass spectrometry (GC×GC--HRToFMS) revealed specific accumulation of typically unmonitored POPs-like compounds in raptors.
