Abstract Natural polysaccharides have received much attention for their ability to ameliorate hepatic steatosis induced by high-fat diet. However, the potential risks of use been less investigated. Here, we show that exopolysaccharides (EPS) from Lactobacillus rhamnosus GG (LGG) and L. casei BL23 reduce in zebrafish fed a diet, while EPS, but not LGG induce liver inflammation injury. This is due fact EPS induces gut microbial dysbiosis, promotes homeostasis. We find can directly activate...
We report on the fabrication of depressed cladding waveguide lasers in Nd:YAG (neodymium doped yttrium aluminum garnet, Nd:Y3Al5O12) ceramics microstructured by femtosecond laser pulses. Full control over confined light spatial distribution is demonstrated high contrast waveguides with hexagonal, circular and trapezoidal configurations. The confocal fluorescence measurements reveal that original luminescence features Nd3+ ions are well-preserved regions. Under optical pump at 808 nm, showed...
The van der Waals (vdWs) heterostructures, with vertical layer stacking structure of various two-dimensional (2D) materials, maintain the reliable photonic characteristics while compensating shortcomings participating individual components.

Gypenosides (Gyps), the major botanical component of Gynostemma pentaphyllum, was found to up-regulate farnesoid X receptor (FXR) in a mouse model non-alcoholic steatohepatitis (NASH). However, exact role FXR and underlying mechanisms Gyps-mediated effects on NASH remain be elucidated.This study investigated whether Gyps attenuates through directly activating high-fat diet (HFD)-induced NASH, delineated molecular pathways involved.A HFD-induced NSAH used examine with obeticholic acid (OCA)...
Depressed cladding waveguides are fabricated in Pr:LiYF4 (YLF) crystal by femtosecond laser inscription following a helical scheme.

Currently, AIEgen‐photochromics conjugates and intrinsic photochromic AIEgens are the two major molecular design strategies for photoresponsive AIE materials. However, these still have their own limitations. In our previous research, we discovered pyrimido[2,1‐b][1,3]benzothiazole (PBT) as a novel core structure of AIEgens. We herein explored chimeric strategy to rationally integrate bisthienylethene (BTE) orthogonal head group into new PBT molecule (PBTE). Compared conventional strategies,...
Dielectric crystals, despite their rich optical properties and great potential in integrated optoelectronics, had generally fallen behind the competing photonic platforms, mainly due to significant difficulties of material processing. By combining unique capabilities ion implantation photosensitization femtosecond laser direct writing (FsLDW) nanostructuring, this study, we propose an innovative methodology harnessing high energy focused localized surface plasmon resonance (LSPR) embedded...
ABSTRACT Human papillomavirus type 16 (HPV16) is a high-risk virus linked to cervical cancer, primarily through its oncogenic proteins E6 and E7. The HPV16-L1 protein, the major capsid component, plays key role in formation immune response. Monitoring anti-HPV16-L1 antibodies serum crucial for understanding infection dynamics vaccine efficacy. This study aimed develop novel quantum dot-labeled blocking enzyme-linked immunosorbent assay (QDs-B-ELISA) quantitative detection of antibodies....
