Y chromosome sequence and epigenomic reconstruction across human populations.

Recent advances in long-read sequencing technologies have allowed the generation and curation of more complete genome assemblies, enabling the analysis of traditionally neglected chromosomes, such as the human Y chromosome (chrY). Native DNA was sequenced on a MinION Oxford Nanopore Technologies sequencing device to generate genome assemblies for seven major chrY human haplogroups. We analyzed and compared the chrY enrichment of sequencing data obtained using two different selective sequencing approaches: adaptive sampling and flow cytometry chromosome sorting.

Mesoporous Silica Matrix as a Tool for Minimizing Dipolar Interactions in NiFeâ‚‚Oâ‚„ and ZnFeâ‚‚Oâ‚„ Nanoparticles.

NiFeâ‚‚Oâ‚„ and ZnFeâ‚‚Oâ‚„ nanoparticles have been prepared encased in the MCM (Mobile Composition of Matter) type matrix. Their magnetic behavior has been studied and compared with that corresponding to particles of the same composition and of a similar size (prepared and embedded in amorphous silica or as bare particles). This study has allowed elucidation of the role exerted by the matrix and interparticle interactions in the magnetic behavior of each ferrite system.

Effect of composition and coating on the interparticle interactions and magnetic hardness of MFeO (M = Fe, Co, Zn) nanoparticles.

Single domain superparamagnetic ferrite nanoparticles with the composition MFeO (M = Fe, Co, Zn) have been prepared by thermal decomposition of metal acetylacetonates in diphenyl ether or dibenzyl ether, using oleic acid in the presence of oleylamine as a stabilizing agent. The Fe, Co and Zn ferrite nanoparticles are monodisperse with diameters of 4.9, 4.
