Hot deformation behavior of hard-to-deform Ni-based Alloy

Journal of Physics: Conference Series, 2021
Abstract The very poor hot workability of hard-to-deform GH4742 alloy is represented in the aspects of very narrow available deformation temperature range, high deformation-resistant force and low thermoplasticity. In this paper, the hot deformation behavior of a Ni-based superalloy was studied in the temperature range of 1060-1160°C and

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe

FEBS Open Bio, EarlyView.
Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.
