Analysis of Pollution Characteristics and Contributions of Firework Burnings in Nanchang during the Spring Festival.

This study investigates the impact of fireworks on air quality during the Spring Festival in Nanchang City, utilizing high-resolution monitoring data from February 7th to 15th, 2021. Significant variations in K concentrations were observed, indicating severe air quality impacts. During the most intense discharge event A, K concentrations were 20.

LAL test and RPT for endotoxin detection of CPT-11/DSPE-mPEG nanoformulation: What if traditional methods are not applicable?

Endotoxin detection is an important step in drug characterization. Herein we found that a chemotherapeutic drug nanoformulation composed of irinotecan hydrochloride (CPT-11) and an amphiphilic molecule DSPE-mPEG can interfere with the limulus amebocyte lysate assay (LAL). Furthermore, the rabbit pyrogen test (RPT) results indicated that at a relatively high dosage, the drug irinotecan hydrochloride can induce a hypothermia effect which may render the RPT results ambiguous in determination of the safety of the drug formulation.

Hyperpolization-activated Ca(2+) channels in guard cell plasma membrane are involved in extracellular ATP-promoted stomatal opening in Vicia faba.

Extracellular ATP (eATP) plays essential roles in plant growth, development, and stress tolerance. Extracellular ATP-regulated stomatal movement of Arabidopsis thaliana has been reported. Here, ATP was found to promote stomatal opening of Vicia faba in a dose-dependent manner.
