The generator sets made a noise level of 73 dB(A) at a distance of 47 m from the source, where are located the guest rooms. This level was far from the legal regulations for allowable environmental conditions. A noise enclosure with air silencers was proposed to reach a final level of ...
Since both the ζ-and α-globin genes are expressed in primitive erythroid cells in a ratio of ~0.4:0.6 respectively, prior to E12.5 when ζ-globin is being silenced (Supplementary Fig.1)14, we initially compared ATAC-seq across the mouse α-globin cluster and its flanking regions in prima...
We previously showed that repression of the β-globin gene appears to be mediated through two DNA sequences, silencers I and II, and identified a protein termed BP1 which binds to both silencer sequences. In this study, we cloned two cDNAs encoding proteins which bind to an oligonucle...

The therapeutic options for Alzheimer’s disease (AD) are limited, underscoring the critical need for finding an effective regulator of Aβ42 production. In this study, with 489 human postmortem brains, we revealed that homotrimer G protein subunit gamma
