TL;DR: In this paper, fine-grained alloys of Mg-3Al-1Zn-0.2Mn in wt.% were obtained by an equal-channel angular extrusion technique and subsequent annealing at elevated temperatures.

TL;DR: It is shown here that Top3α depletion causes accumulation of cells in G2 phase, enlargement of nuclei, and chromosome gaps and breaks that occur at the same position in sister chromatids, and the transition from metaphase to anaphase is inhibited.

TL;DR: In this article, the diffusion coefficient of 95 Nb in pure Nb and Nb-H alloys whose hydrogen concentration ranges between H / Nb ǫ = 0.05 and 0.34 in atomic ratio has been determined in the temperature range 823 −1598 K using a serial sputter microsectioning technique.

TL;DR: Results suggest that under the former condition, RecQL4-loading depended on DNA replication, while under the latter, the interaction occurred in response to double-stranded DNA breaks (DSBs) induced by EcoRI.

TL;DR: Analysis of the time course of DNA replication and results obtained using geminin, an inhibitor of licensing for DNA replication, suggest that the discrete replication protein A foci formed in response to camptothecin-induced DNA damage occur in a DNA-replication-dependent manner.
