Influencing Factor Analysis on the Anomalously Low-Friction Effect in the Block Rock Mass

Advances in Civil Engineering, 2020
According to the instability failure of the deep rock mass, a superposition block model of anomalously low-friction effect was established. The numerical results were compared with the previous experiment, which verifies the feasibility and effectiveness

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Numerical Investigation and Factorial Analysis of Residual Displacement in Rocking Self-Centering Bridge Columns Under Cyclic Loading

Buildings
Well-designed rocking self-centering (RSC) columns are capable of achieving small residual displacement. However, quantitative assessments of residual displacement mechanisms in RSC columns remain understudied. The residual displacement is the product of

Study on Distribution Characteristics and Displacement Mechanism of Microscopic Residual Oil in Heterogeneous Low Permeability Reservoirs

Geofluids, 2019
In order to explore the development methods suitable for heterogeneous low permeability reservoirs and study the distribution characteristics of residual oil, photoetched glass and artificial core models with three permeability ratios of 1, 6, and 9 were

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Displacement of the Residual Liver Cavity in Laparoscopic Echinococcectomy

Surgical Science, 2020
Aim: This article aimed to investigate the analysis of various methods for eliminating the residual liver cavity after laparoscopic echinococcectomy in patients. Methods: The authors used the following methods of eliminating the residual cavity: omentoplasty (36.8%), abdominalization (30%), drainage of the residual cavity (26.2%), and a combination of ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Experimental investigation of laminar and turbulent displacement of residual oil film

Scientific Reports, 2023
AbstractResidual oil films on pipe walls are a common occurrence in industrial processes, and their presence can significantly impact system efficiency and performance. However, the mechanisms that govern oil film removal by an immiscible displacing fluid from the internal walls of pipes under different flow regimes, including laminar and turbulent ...
