Preventive and controlling effects of -acetylneuraminic acid in regulating glucose and lipid metabolism disorders the gut-liver axis in high-fat diet mice.

A high-fat diet may disrupt sialic acid homeostasis indirectly by altering the gut microbiota and metabolic pathways. Sialic acid interventions have immune-regulatory effects and can improve gut health, but their impact on glucose and lipid metabolism disorders, both before and after obesity induced by a high-fat diet, remains unclear. This study used two models: a preventive experiment (intervention during high-fat diet feeding) and a control experiment (intervention after obesity induction).

Efficient generation of Bessel-Gauss attosecond pulse trains via nonadiabatic phase-matched high-order harmonics.

Generating Bessel-Gauss beams in the extreme ultraviolet (EUV) with attosecond pulse durations poses a significant challenge due to the limitations of conventional transmission optical components. Here, we propose a novel approach to produce such beams by inducing an annular EUV source through high-order harmonic generation (HHG) under nonadiabatic phase-matching conditions. The resulting light pulse maintains temporal coherence and manifests attosecond pulse trains as confirmed by the reconstruction of attosecond beating by interference of two-photon transitions (RABBIT) measurements.

Femtosecond Time-Resolved Neighbor Roles in the Fragmentation Dynamics of Molecules in a Dimer.

How the neighbor effect plays its role in the fragmentation of molecular clusters attracts great attention for physicists and chemists. Here, we study this effect in the fragmentation of N_{2}O dimer by performing three-body coincidence measurements on the femtosecond timescale. Rotations of bound N_{2}O^{+} triggered by neutral or ionic neighbors are tracked.

What's the choice for goji: Lycium barbarum L. or L. chinense Mill.?

Ethnopharmacological Relevance: For over one millennium, goji berries have been used traditionally as food and medicine in eastern Asia. In recent decades, it has become increasingly popular globally. However, the biocultural development of goji is poorly known.

Preconcentration of nickel and cadmium by TiO2 nanotubes as solid-phase extraction adsorbents coupled with flame atomic absorption spectrometry.

TiO(2) nanotubes, a new nanomaterial, are often used in the photocatalysis. Due to its relatively large specific surface areas it should have a higher enrichment capacity. However, very few applications in the enrichment of pollutants were found.
