Wide spectral coverage terahertz frequency upconversion detection with organic crystal OH1.

Organic-crystal-based optical terahertz (THz) sources and detectors are powerful tools for THz spectroscopy, owing to the wide frequency tunability. A drawback of this technique lies in the inherent absorption peaks of nonlinear crystals, leaving several gaps in the spectral coverage. As an alternative type of organic crystal, hydrogen-bonded OH1 is promising to complement the existing gaps.

Widely tunable long-wave infrared difference frequency generation with a BaGaSe crystal.

We report an experimental study of long-wave infrared difference frequency generation based on crystal. The sources of two input wavelengths were the fundamental output of a Nd:YAG laser and its second-harmonic pumped ∼1.2µ optical parametric oscillator.

GBX2, as a tumor promoter in lung adenocarcinoma, enhances cells viability, invasion and migration by regulating the AKT/ERK signaling pathway.

Background: Increasing evidence shows that gastrulation brain homeobox 2 (GBX2) is involved in multiple cancers. However, whether GBX2 has an effect on the lung adenocarcinoma remains unclear. In the present study, we investigated the functions of GBX2 on lung adenocarcinoma and explored the underlying mechanism.
