Numerical Modelling of Multi-directional Earthquake Loading and Its Effect on Sand Liquefaction [PDF]

, 2015
Earthquakes generate multi-directional ground motions, two components in the horizontal direction and one in the vertical. Nevertheless, the effect of vertical motion on site response analysis has not been the object of extensive research.

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

Advanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Allogeneic Immune Cell Perfusion Inhibits the Growth of Vascularized 3D In Vitro Tumor Models, Induces Vascular Regression and Desmoplasia, but Promotes Tumor Cell Invasion

Advanced Science, EarlyView.
This study presents a vascularized 3D tumor model to investigate immune–stromal–tumor interactions under allogeneic PBMC perfusion. While immune cells induced tumor shrinkage, they also promoted vascular regression, stromal activation, and cancer cell invasion.
