The objective of this research was to investigate the catalytic role of nitrogen-doped carbon nanotubes (NCNTs) in a bioreactor that contained Acidithiobacillus ferrooxidans (A. ferrooxidans) and waste printed circuit boards (WPCB). Factors that could refl ect the results, such as pH, oxidation-reduction potential (ORP), Fe²⁺, and leaching rate of copper were detected and calculated in the bioleaching...
For investigating the protective roles of antioxidative system in desiccation tolerance of Caragana species as they adapt to arid environments, we monitored a variety of ecophysiological parameters in the leaves of Caragana arborescens (mesophyte), C. microphylla (semiarid species), C. roborovskyi, C. stenophylla, C. acanthophylla, and C. tragacanthoides (xerophyte) grown under a drying-rehydration...
Double minute chromosomes (DMs) are the cytogenetic hallmark of extra-chromosomal genomic amplification. The frequency of DMs in primary cancer and the cytogenetic features of DMs-positive primary cancer cases are largely unknown. To unravel these issues, we retrieved the Mitelman database and analyzed all DMs-positive primary cancerous karyotypes (787 karyotypes). The overall frequency of DMs is...
