Rock magnetism

open access: yesEos, Transactions American Geophysical Union, 1971
Work in rock magnetism during the last 4 years in the United States has been concentrated on several important intrinsic problems, the solutions of which are needed to answer some of the larger questions now being raised in paleomagnetism. The questions include whether it is feasible to measure variations in geomagnetic field intensity in rocks as old ...

Magnetic Difference Between Deep and Surface Soil Within an Agricultural Area in Southern China: Implications for Magnetic Mineral Transformation During Pedogenic Process Under Subtropical Climate

open access: yesEarth and Space Science, 2020
Mineral magnetism is proved as a sensitive method of pedogenesis by numerous studies. However, formation pathways of magnetic minerals and subsequent magnetic response are quite different under different climate.

DDX3X induces mesenchymal transition of endothelial cells by disrupting BMPR2 signaling

open access: yesFEBS Open Bio, EarlyView.
Elevated DDX3X expression led to downregulation of BMPR2, a key regulator of endothelial homeostasis and function. Our co‐immunoprecipitation assays further demonstrated a molecular interaction between DDX3X and BMPR2. Notably, DDX3X promoted lysosomal degradation of BMPR2, thereby impairing its downstream signaling and facilitating endothelial‐to ...
