The dynamic epitranscriptome N6-methyladenosine and

N 6-methyladenosine (m 6 A) is a modified base that has long been known to be present in noncoding RNAs, ribosomal RNA, polyadenylated RNA and at least one mammalian mRNA. However, our understanding of the prevalence of this modification has been fundamentally redefined by transcriptome-wide m 6 A mapping studies, which have shown that m 6 A is present in a large subset of the

Research on Toxicity Character of Cathode Ray Tubes Using

Cathode ray tubes (CRTs) present a disposal problem because of their large magnitude and their role as a major source of lead. Toxicity Characteristic Leaching Procedure (TCLP) is used to determine whether a solid waste is a hazardous waste. A dynamic leaching procedure with series of leaching solutions was developed to evaluate the leaching toxicity of CRT glass in the environment.
