A Quantitative Characterization Method for Pore-Scale Wettability of Shale Oil Rocks Based on Nuclear Magnetic Resonance Technology

Yankuang ceshi
Rock wettability governs the occurrence state and flow behavior of crude oil within pores and is critical for enhancing oil recovery. However, shale oil rocks typically contain micro/nanoscale pore throats and are characterized by strong tightness and ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
