Transcriptomic analysis of treated by a potential phytonematicide, punicalagin.

Punicalagin showed significant nematotoxic activity against pine wood nematode (PWN), , in the authors' previous research. The authors performed high-throughput transcriptomic sequencing of punicalagin-treated nematodes to generate clues for its nematotoxic mechanism of action. The authors identified 2,575 differentially expressed genes, 1,428 of which were up-regulated and 1,147 down-regulated.

[Nutrient contents and heavy metal pollutions in composted sewage sludge from different municipal wastewater treatment plants in Beijing region].

Changes of nutrient contents and heavy metal pollutions in composted sewage sludge from different municipal wastewater treatment plants (as represented by CSS-A and CSS-B, respectively) in Beijing region were investigated. The results showed that the pH values, nutrient contents, trace elements and heavy metals in CSS-A and CSS-B depended on the sludge resources and particular years. The average of organic matter content in different years (203 338.
