PDIA6–SCD1 Axis Rewires Lipid Metabolism to Drive Gastric Cancer Progression
Advanced Science, EarlyView.Protein disulfide isomerase A6 (PDIA6) is identified as an oncogenic driver in gastric cancer. PDIA6 directly binds and stabilizes SCD1 by limiting its ubiquitin–proteasome‐mediated degradation, thereby sustaining monounsaturated fatty acid (MUFA)‐enriched lipid homeostasis and lipid metabolic reprogramming.

A Faraday isolator based on fused silica in a Herriott cell [PDF]
EPJ Web of ConferencesWe demonstrated a multipass Faraday isolator based on fused silica. The polarization rotation angle of 45° was accumulated in a Herriott cell. The concept enables the use of magneto-optic materials with low Verdet constants in Faraday isolators.

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.Graphical summary of the study design, intervention, and outcomes. ABSTRACT Background Patients with biliary tract cancer (BTC) often have actionable mutations, and comprehensive genomic profiling (CGP) plays an important role. However, the feasibility of CGP using transpapillary biopsy (TPB) samples remains unclear.

In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air
Laser &Photonics Reviews, EarlyView.Air‐breakdown acoustics at the laser focus is used to determine femtosecond pulse duration with a simple USB microphone. By chirp‐tuning and compressing 1030 nm pulses from 241 to 50 fs, the acoustic amplitude scales inversely proportional to the square root of the pulse duration, enabling in situ readout over 50 fs–5 ps—crucial for precise pulse ...
