Screening and identification of lactic acid bacteria with α-glucosidase inhibiting activity
Published 2025-07-01Get full textIn this study, lactic acid bacteria were isolated from traditional fermented foods in Guizhou. The fermentation supernatant and cell disruption extract were used to screen lactic acid bacteria with α-glucosidase inhibitory activity, and the active lactic acid bacteria strains with potential hypoglyc...

Enhanced Modal Coupling Loss in a Two-Mode SOI Waveguide of Broken Parity-Time Symmetry
Published 2018-01-01Get full textEffect of optical loss, presented in a superstructure grating with a complex refractive index profile, on the mode coupling is studied in a two-mode silicon-on-insulator waveguide. In this scheme, both our theory and experimental results indicate that the optical loss not only provides optical absor...

Time-evolution of ScCO2-weakened coal integrity: Chemo-hydromechanical coupling and geological sequestration implications
Published 2025-06-01Get full textGeological sequestration of CO2 is critical for deep decarbonization, but the geomechanical stability of coal reservoirs remains a major challenge. This study integrates nanoindentation, XRD/SEM-EDS chemo physical characterization and 4D CT visualization to investigate the time-evolving mechanical d...

Efficient Second Harmonic Generation by Mode Phase Matching in a Silicon Waveguide
Published 2017-01-01Get full textBulk silicon possesses no second-order susceptibility (χ<sup>(2)</sup>), inhibiting second-order nonlinear processes in the emerging silicon photonic platform. Here, we propose a method to overcome this limitation by enabling a third-order (χ<sup>(3)</sup&g...

Ferroptosis is important for Toxoplasma gondii replication and virulence in vitro and in vivo
Published 2025-12-01Get full textThe protozoan parasite T. gondii employs intricate mechanisms to exploit host cells while sustaining their viability, yet its interaction with ferroptosis – an iron-dependent cell death driven by lipid peroxidation – remains poorly defined. Here, we show T. gondii infection induces ferroptotic hallm...
