Pyrroloquinoline quinone (PQQ) has a variety of biological functions. However, rare attention has been paid to its effects on exercise-induced damage. Here, we assessed the potential protective effects of PQQ against the fatigue and oxidative damage caused by repeated exhaustive exercise, and studied the underlying mechanism.

At present, spraying works on the outer surface of hull blocks are mainly performed by workers with the help of climbing scaffolds, which has several disadvantages such as low efficiency, low quality and harmfulness to workers' health. This paper proposed a robot arm which can replace humans to carry out spraying works for large vessel facades. However, the whole spraying system was consisted of a big mobile platform and a lightweight spraying robot arm, possessing a large work space. According to the requirements of load capacity and explosion-proof property, the mechanical configuration and length of the robot arm were carefully designed and optimized to permit the spraying robot arm with light weight, high load capacity and high safety. Finally, simulations were performed on the work space and joint torques to verify the good performances of the new lightweight spraying robot arm.978-1-4673-9675-2/15/$31.00 © 2015 IEEE

With the continuous development of rail transit industry, the comfort level of drivers and the flexibility requirements of customers for the different vehicle of console are continuously improved. At present, the lifting pedal has been widely used in the industry, which are hydraulic and electric type. Pure mechanical lifting pedal has not been applied in the rail transit vehicles. Considering the service life and reliability of the products, many customers, especially foreign customers, require the pure mechanical structure to meet the requirements of different vehicle models and meet the requirements of different drivers for the console. This paper proposes a kind of pure mechanical lifting pedal applied to rail transit vehicles, which can meet the adaptability of the console to different vehicle bodies and drivers, and greatly improve the universality and reliability of the application.
