Cyclic GMP-AMP synthase (cGAS) and stimulator of interferon genes (STING) are essential components the innate immune sensors to cytosolic DNA elicit type I (IFN). Recent studies have revealed that manganese (Mn) can enhance cGAS STING activation viral infection. However, role Mn in antitumor immunity has not been explored. Here, we designed a nanoactivator, which induce presence cytoplasm simultaneously elevate Mn2+ accumulation within tumor cells. In detail, amorphous porous phosphate...

When the deep tunnel passes through a water-rich fault zone, it is prone to disasters such as large deformation of soft rock, which brings great challenges construction safety. In this paper, multi-field coupling model established based on finite element method (FEM), discrete (DEM), and computational fluid dynamics (CFD) method, can simulate interaction between structure, fractured rock mass, flow field. The correctness verified on-site monitoring data. On basis, stability surrounding when...

Uniaxial compressive strength (UCS) and tensile are essential parameters of rocks, but the direct measurement these two is time-consuming requires high-quality samples. As such, academics brought attention to indirect tests (such as point load test, ultrasonic wave velocity Schmidt hammer test) that could be used estimate UCS quickly. The empirical equations for estimating rocks in study cases remain poorly understood previous based on testing methods possess a lithological...

Abstract In this study, a high effective phosphorus‐containing flame retardant (DOP‐DDM) was synthesized using phenylphosphonic dichloride, p ‐hydroxybenzaldehyde, 9,10‐dihydro‐9‐oxa‐10‐phosphaphenan‐ threne‐10‐oxide (DOPO) and 4,4′‐diaminodiphenyl methane (DDM) as raw materials. The chemical structure of DOP‐DDM confirmed by Fourier transform infrared spectroscopy (FT‐IR), 1 H nuclear magnetic resonance ( NMR) 31 P NMR). epoxy resin (EP) material with 4.7 wt% (EP‐4.7) can reach V‐0 degree...

Promoting the coupled and coordinated development of China’s tourism industry urbanization is great significance for its marginal less developed regions. Taking a typical region, mountainous border areas Western Yunnan as research object, this study analyzed spatial temporal characteristics coupling coordination degree urbanization, well their influencing factors, in region from 2010 to 2019 using model, gravity panel Tobit model. The results show following. (1) level had significantly...
