Modified band and loop space maintainer: Mayne's space maintainer
International Journal of Pedodontic Rehabilitation, 2018 Primary teeth play a pivotal role in preventing malocclusion of permanent dentition. When there is premature tooth loss, the space should be maintained for preserving the arch form and preventing space loss. Space maintainer is the treatment of choice in such conditions. When the conventional method is not applicable, we plan for modifications. In this

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
