Functional Optical Fibers with Tailored Side Emission from Modified Rod‐in‐Tube Preforms

open access: yesAdvanced Photonics Research, EarlyView.
A modified rod‐in‐tube method enables fabrication of functional optical fibers with tailored light‐diffusing properties. The approach incorporates optically active species at a well‐defined radial position within an otherwise homogeneous fiber core. Using lanthanide ions and noble metal nanoparticles as active species demonstrates wavelength conversion

Conjugated Lithocholic Acid Activates Hepatic TGR5 to Promote Lipotoxicity and MASLD‐MASH Transition by Disrupting Carnitine Biosynthesis

open access: yesAdvanced Science, EarlyView.
Takeda G protein‐coupled receptor 5 (TGR5) serves as a central regulator in the metabolic dysfunction‐associated steatotic liver disease (MASLD)/metabolic dysfunction‐associated steatohepatitis (MASH) transition via conjugated lithocholic acid (LCA). Mechanistically, TGR5 orchestrates lipotoxicity‐induced cell death through its interaction with CD36 ...
