A growing body of experimental evidence suggests that microRNAs (miRNAs) are closely associated with specific human diseases and play critical roles in their development and progression. Therefore, identifying miRNA related to specific diseases is of great significance for disease screening and treatment. In the early stages, the identification of associations between miRNAs and diseases demanded laborious and time-consuming biological experiments that often carried a substantial risk of failure.

Methods: We conducted a retrospective cohort study involving all cases of placenta previa among 56 070 singleton births at two tertiary care hospitals in Guangdong, China, between January 2014 and December 2018.
DNA methyltransferase (MTase) is related to transcriptional repressor activity in biological functions. It is an essential for cancer diagnosis and therapeutics to detect DNA MTase activity sensitively. Here, a fluorescent system based on polymerase amplification has been developed to detect DNA adenine MTase (Dam) activity sensitively.

Notably, the catalytic system also efficiently catalyzed the reaction under aqueous conditions.
