Objectives Small nucleolar RNAs (snoRNAs) form clusters within the genome, representing a mysterious category of small non-coding RNAs. Research has demonstrated that aberrant snoRNAs can contribute to the development of various types of cancers. Rec

Background: P-element induced wimpy testis (PIWI)-interacting RNAs (piRNAs) are the most mysterious class of small non-coding RNAs. They limit gene expression in gonads and sequence diversity. Dysregulated piRNAs can led to all kinds of cancers. Rece

Isothermal compression tests were carried out on a spray-formed ultrahigh carbon steel (UHCS-3.0Si) by Gleeble 1500 system. The true stress increases with the decrease of temperature and increase of strain rate. The deformation activation energies, Q
