Alterations in brain metabolites in rats with experimental periodontitis: A metabolomic approach

open access: yesJournal 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.

Prevalence and local factors associated with radiographic bone loss in primary dentition: A retrospective study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This study aimed to evaluate the radiographic bone level in primary molars in a Brazilian population, define the prevalence of bone loss, and identify the local factors associated with early bone alterations. Methods Radiographs of children who attended Piracicaba Dental School (Brazil) between 2014 and 2020 were evaluated.

Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

open access: yesJournal of Raman Spectroscopy, EarlyView.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

open access: yesJournal of Raman Spectroscopy, EarlyView.
A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.
