[Evaluating the growth status and threatened factors for old trees in China].
Ying Yong Sheng Tai Xue Bao
October 2021
Article Synopsis
- Old trees play a vital role in ecosystems and have significant genetic diversity; there are approximately 10.66 million old trees in China, mainly concentrated in Inner Mongolia and Yunnan.
- Most old trees (94.3%) are healthy, but threats like pests and diseases (81.4% of counties) and natural disasters (66.7% of regions) are significant challenges to their survival.
- To enhance protection, modern technologies such as drones for monitoring and the creation of a database for old tree resources are recommended to prevent illegal activities and improve management efforts.
Purpose: OnabotulinumtoxinA is approved in the Republic of Korea for the treatment of moderate-to-severe crow's feet lines (CFL) and glabellar lines (GL), separately or in combination. We assessed safety and effectiveness of onabotulinumtoxinA in real-world clinical practice.
Patient And Methods: This 4-year postmarketing surveillance study was conducted in the Republic of Korea in subjects with moderate-to-severe CFL.
[Determination of chlorophyll a and b using absorption spectrum].
Guang Pu Xue Yu Guang Pu Fen Xi
January 2008
Article Synopsis
- * The authors transformed previous data on the absorption spectra of chlorophyll a and b into a transmission spectrum to visually identify their colors.
- * By using colorimetry principles and a standard light source, they plotted the chromaticity coordinates of chlorophyll a (cyan region) and b (yellowish green region) on a chromaticity diagram, providing a foundation for a new, non-invasive technology to assess pigment content in plants.
