The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Analysis and research on vertical displacement of ground surface and station caused by shield cutting diaphragm wall of station

open access: yesYantu gongcheng xuebao
This paper takes the project of Tianjin Metro shield cutting the existing station's diaphragm walls as the background. Through on-site monitoring, theoretical analysis and other methods, it deeply studies the variation laws of the vertical displacements ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

A New Modified Peck Formula for Predicting the Surface Settlement Based on Stochastic Medium Theory

open access: yesAdvances in Civil Engineering, 2019
Peck method and stochastic medium method are the two most commonly used methods to estimate surface settlement caused by tunnel excavation. However, the Peck method was not suitable for a shallow-buried tunnel, and the calculation process of the ...

Ground Settlement of Deeply Buried Two-Lane Tunnels with Large Cross-Sections Using Different Construction Methods

open access: yesApplied Sciences, 2022
To ensure the safety of excavations such as large section tunnels of the Guangxi Liubin Highway Tunnel Project, we implemented a simulation analysis of 3D tunnel models based on finite software for different construction methods.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Research on historical deformation and rock layer water content variation in large open-pit mining areas based on SBAS and MatDEM

open access: yesFrontiers in Earth Science
In order to study the characteristics of settlement and deformation evolution of large open pit to underground mine quarries in China, and to analyse the changing law of volumetric water content of overburden rock layers at different mining stages. Based

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Influence Mechanisms of Earth Pressure Balance Shield Tunneling Parameters on Chamber Pressure and Surface Settlement: A Theoretical and FDM-DEM Coupled Analysis

open access: yesApplied Sciences
In earth pressure balance (EPB) shield tunneling, chamber pressure control is essential for maintaining excavation-face stability and limiting surface settlement.
