In-Orbit Calibration of Phase Retardance for Channeled Spectropolarimeter.

The phase retardance of the optical system (PROS) is a crucial factor limiting the accuracy of the Stokes vector reconstruction for the channeled spectropolarimeter. The dependence on reference light with a specific angle of polarization (AOP) and the sensitivity to environmental disturbance brings challenges to the in-orbit calibration of PROS. In this work, we propose an instant calibration scheme with a simple program.

Claudin18 associated with corticosteroid-induced expression of surfactant proteins in pulmonary epithelial cells.

Objective: The present study was undertaken to test the hypothesis that if Cldn18 is associated with lung maturation and play a key role in the corticosteroid-induced expression of surfactant proteins.

Methods: Mouse embryonic lung tissue at different developmental stages (E14.5, E16.

[Promotive effect and its molecular mechanism of KLF5 on gemcitabine-induced apoptosis in human lung adenocarcinoma cell line H441].

Objective: To investigate the effects of kriippel-like factor 5 (KLF5) overexpression on gemcitabine (GEME)-induced lung adenocarcinoma cell apoptosis and its molecular mechanisms.

Methods: Lung adenocarcinoma cell line H441 were transfected with KLF5 plasmid or control plasmid. 68 h later, cells were treated with 100 nmol/L GEME for 4 h, then cell number counting and flow cytometry were applied to detect cell proliferation and apoptosis; Western blot were used to analyse the expression level of KLF5, RT-PCR were used to analyse the KLF5 gene, apoptosis-related genes CD95 and BAX; Immunofluorescence staining was performed to detect the expression level of apoptosis-related protein Caspase 3.
