Disease‐Stage Synchronized Nanozyme Therapy for Polymicrobial Sepsis through Adaptive Catalytic and Immune Reprogramming

Advanced Science, EarlyView.
A disease‐stage synchronized nanozyme platform is developed to treat polymicrobial sepsis by adapting its functions to changing infection environments. The system eliminates multidrug‐resistant bacteria during early infection while reducing inflammation and restoring immune balance during recovery, providing an integrated strategy for infection control

Zonal prediction of the heights of water-conducting fracture zones under varying overburden types in North China-type coalfields

Meitian dizhi yu kantan
BackgroundThe gradual increase in the exploitation depth and intensity of coal resources in the North China-type coalfields has caused problems such as overburden movement and damage, as well as fracture evolution.

Gut Microbiota‐Isoallolithocholic Acid Crosstalk Promotes Calcium Oxalate Kidney Stone Formation via PARP1‐Mediated Parthanatos

Advanced Science, EarlyView.
ABSTRACT Bile acids have been implicated in calcium oxalate (CaOx) nephrolithiasis. Here, we employ multi‐omics approaches to identify isoallolithocholic acid (isoalloLCA) as the key bile acid elevated in the feces, serum, kidney, and urine of CaOx rats, confirmed by spatial metabolomics.

A Microenvironment‐Adaptive Scaffold Rejuvenates Peripheral Nerve Regeneration During Aging Via Dual Modulation of Ferroptotic Stimuli in Schwann Cells

Advanced Science, EarlyView.
(i) Aging impairs peripheral nerve regeneration via its dual ferroptosis‐mediated pathologies in senescent schwann cells. (ii) The composite nerve conduit is a symbiosis niche integrating microenvironment‐responsive nanoparticles (Ga‐PTAs) and maxillofacial‐derived mesenchymal stem cells (Mmscs).

The Stress and Displacement Analysis of the Cut-Off Wall for the Deep Overburden Dam

, 2011
The Duncan-Chang nonlinear constitutive model is used to carry out a three-dimensional finite element analysis of Xia Ban Di deep overburden dam with clay core. The regularities of the horizontal displacement, vertical stress and stress level for the cut-

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

Advanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced

Selective coal mine overburden treatment with topsoil and compost to optimise pasture or native vegetation establishment

, 2016
Overburden at a coal mine in the Hunter Valley, New South Wales, was stored in a flat-topped artificial mound with 14-degree side slopes. Topsoil was scarce, dispersive and readily eroded.
