Application of magnetic resonance imaging (MRI) technology in the characterization of microstructure and moisture content of young Moso bamboo.

Bamboo nodes play a key role in the hollow structure and the rapid growth of bamboo culm. Studying on the anatomical structure of bamboo is helpful to understand its growth mechanism. Taking the noninvasive, high-resolution and accurate technical advantages of magnetic resonance imaging (MRI), we conducted cross-sectional high-resolution MRI scanning on the tip of young Moso bamboo culm (removed shoot sheath) and extracted the gray value of the MRIs by using MATLAB software to explore the differences of water distribution in nodes, proximal nodes, and internodes.

Effect of low-dose fenvalerate on semen quality capacitation in adult mice.

Background: Fenvalerate (FEN) has been demonstrated to be a reproductive toxicant in humans and rodents. However, little is known about whether short-term exposure to low-dose FEN produces reproductive toxicity.

Methods: We administered FEN (0.
