RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Technical Study on Dual-Mirror Cooperative Frequency-Stabilized Induced Backscatter Angle Control for Locking Zones

IEEE Photonics Journal
The backscatter-induced lock-in effect constitutes a primary error source in laser gyroscopes, with the lock-in threshold critically dependent on the magnitude of the backscatter angle. Conventional dual-mirror synchronous frequency stabilization suffers

Frequency stability of a wavelength meter and applications to laser frequency stabilization [PDF]

, 2015
Interferometric wavelength meters have attained frequency resolutions down to the MHz range. In particular, Fizeau interferometers, which have no moving parts, are becoming a popular tool for laser characterization and stabilization.

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

FEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.
