Dietary lycopene is negatively associated with abdominal aortic calcification in US adults: a cross-sectional study.

Background: Vascular calcification (VC) is one of the complications of chronic kidney disease (CKD) patients. Previous studies have confirmed that oxidative stress (OS) plays an important role in developing VC and that antioxidants have anti-VC effects.

Objectives: Our study aimed to determine the relationship between the intake of antioxidants from dietary sources and the prevalence of VC, especially in the CKD population.

All-Optical Tuning of Light in WSe-Coated Microfiber.

The tungsten diselenide (WSe) has attracted considerable interest owing to their versatile applications, such as p-n junctions, transistors, fiber lasers, spintronics, and conversion of solar energy into electricity. We demonstrate all-optical tuning of light in WSe-coated microfiber (MF) using WSe's broad absorption bandwidth and thermo-optic effect. The transmitted optical power (TOP) can be tuned using external incidence pump lasers (405, 532, and 660 nm).
