Twenty-five years ago, the concept of using Agrobacterium tumefaciens (soil gm-ve bacterium) as a vector to create transgenic plants (natural transformation) was viewed as a prospect and a “wish.” Transgenic plants generated by direct DNA transfer methods (e.g., polyethylene glycol or liposome-mediated transformation, electroporation, or particle bombardment) often integrate a large number of c...

Biodiversities can differ substantially among different wastewater treatment plant (WWTP) communities. Whether differences in biodiversity translate into differences in the provision of particular ecosystem services, however, is under active debate. Theoretical considerations predict that WWTP communities with more biodiversity are more likely to contain strains that have positive effects on th...

Previous investigations into the health effects of nitrogen oxides (NOx) have mostly been conducted with special reference to nitrogen dioxide (NO2) and its direct effects on the respiratory system, while the study of nitric oxide (NO) has been disregarded. We carried out a study on NO by exposing rats and mice to 15NO or administering 15N-nitrite and 15N-nitrate to these animals by IP injectio...
