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.

Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

open access: yesLaser &Photonics Reviews, EarlyView.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

Molecular Dynamics Study of Melt Structure and Transport Properties of Mg‒Al Alloy

open access: yesMaterials Genome Engineering Advances, EarlyView.
The structural evolution and transport coefficients of the Mg‐Al alloy melt at different temperatures were investigated using molecular dynamics simulation methods. By establishing relationships among structure, diffusion, and viscosity, the microscopic mechanisms behind the temperature‐induced changes in transport properties are revealed. ABSTRACT The

Asymptotics for the Spectrum of the Laplacian in Thin Bars with Varying Cross Sections

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We consider spectral problems for the Laplace operator in 3D rod structures with a small cross section of diameter O(ε)$$ O\left(\varepsilon \right) $$, ε$$ \varepsilon $$ being a positive parameter. The boundary conditions are Dirichlet (Neumann, respectively) on the bases of this structure, and Neumann on the lateral boundary.

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

open access: yesNano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...
