Antimony Exposure Induces Bladder Cancer Metastasis Via Activation of the SUMOylation-Dependent TGF-β/Smad2/3 Axis.

Antimony is an important industrial raw material, known as the "industrial monosodium glutamate", and is widely used in alloys, electronics, chemical engineering, and other fields. Due to its extensive applications, its environmental toxicity and carcinogenic risk have attracted increasing attention. In recent years, numerous studies have reported the carcinogenic risk of antimony, but its role in bladder cancer and the underlying molecular mechanisms have not been fully elucidated.

Methods for improving imaging quality of a small-distance high-speed rotational reflection tracking system.

The imaging quality of a rotational reflection high-speed tracking system is greatly affected by the optical characteristics of the reflector and the depth of field limitations of the imaging system, especially for tracking systems working in small distances. In order to improve the imaging quality, this paper focused on two factors that affect the imaging quality: double vision caused by the optical characteristics of reflectors and blurring caused by the depth of field of imaging systems. This paper quantified the impact of these two factors on imaging through theoretical analysis, proposed a method of changing the hardware position, and conducted a simulation and experiments.
