LncRNA PROX1-AS1 Facilitates Gastric Cancer Progression via miR-877-5p/PD-L1 Axis.

Introduction: Growing evidences imply that multiple long non-coding RNAs (lncRNAs) play a significant role in the treatment of cancer. Therefore, it is of great significance to discover new biomarkers or therapeutic targets of gastric cancer (GC). However, the potential molecular mechanism of lncPROX1-AS1 in GC remains unknown.

Self-Q-switched, orthogonally polarized, dual-wavelength laser using long-lifetime Yb³⁺ crystal as both gain medium and saturable absorber.

A novel self-Q-switched and orthogonally polarized dual-wavelength laser has been investigated with Yb³⁺-doped CGB disordered crystals. By slightly inclining output coupler to introduce the Fresnel loss, we realized simultaneously dual-wavelength laser operation at 1052.6 nm in E//b polarization and 1057.
