Hydrogen Bonding Polarization Strengthening the Peptide-Based Hydrogels.

Peptide-based hydrogels form a kind of promising material broadly used in biomedicine and biotechnology. However, the correlation between their hydrogen bonding dynamics and mechanical properties remains uncertain. In this study, we found that the adoption of β-sheet and α-helix secondary structures by ECF-5 and GFF-5 peptides, respectively, could further form fiber networks to immobilize water molecules into hydrogels.

Ferrostatin-1 improves acute sepsis-induced cardiomyopathy via inhibiting neutrophil infiltration through impaired chemokine axis.

Introduction: Sepsis-induced cardiomyopathy is a common complication of sepsis and is associated with higher mortality. To date, effective diagnostic and management strategies are still lacking. Recent studies suggest that ferroptosis plays a critical role in sepsis-induced cardiomyopathy and ferroptosis inhibitor Ferrostatin-1 (Fer-1) improved cardiac dysfunction and survival in lipopolysaccharide (LPS) induced endotoxemia.

Catalytically inactive subgroup VIII receptor-like cytoplasmic kinases regulate the immune-triggered oxidative burst in Arabidopsis thaliana.

Protein kinases are key components of multiple cell signaling pathways. Several receptor-like cytoplasmic kinases (RLCKs) have demonstrated roles in immune and developmental signaling across various plant species, making them of interest in the study of phosphorylation-based signal relay. Here, we present our investigation of a subgroup of RLCKs in Arabidopsis thaliana.

Quaternized Molecular Brush-Grafted Injectable Microgel with Anti-Inflammatory and Drainage Properties for Efficient Therapy of Anal Fistula.

Anal fistula is a common disease with recurrent inflammation and accumulated exudate. Traditional treatments often fail to effectively eliminate inflammation and ensure adequate drainage, leading to prolonged healing time and a high recurrence rate. Herein, a new class of quaternized molecular brush-grafted injectable microgel (denoted as GAA@CNT-g-PVBTMA) is developed through thermal polymerization and mechanical fragmentation to promote the healing process of anal fistula.

In recent years, altered metabolism has been shown to contribute to the maintenance of pancreatic cancer malignancies. However, the molecular mechanism underlying glucose metabolism reprogramming remains elusive.

Specific capture of magnesium ions by phosphorus atomic sites on self-floating nuclei advances Mg/Li separation in salt lakes brine.

Efficient magnesium-lithium separation is a critical step in extracting lithium ions from salt lakes brine. Precipitation of Mg from liquid to solid is the simplest separation method, but a side reaction of Li adsorption by precipitated floc leads to incomplete Mg/Li separation and lithium loss. In this study, we grafted phosphorus atomic sites onto silica-based nuclei with self-floating separation capability to prepare adsorbents with specific capture ability for Mg, achieving efficient Mg/Li separation from brine.

Numerical study on effects of interfacial roughness and microcracks on stress distribution in thermal barrier coatings with temperature drop.

This paper establishes a finite element model that includes the interface roughness characteristics to evaluate the stress concentration in the atmospheric plasma sprayed (APS) thermal barrier coatings (TBCs) with an uneven temperature field. We further scrutinize the effects of crack initiation at the interface between the thermally grown oxide (TGO) and the bond coat (BC) and in the ceramic top-coat (TC) on stress redistribution by introducing the debonding model for crack analysis. Results indicate that the interfacial residual stress σ achieves the critical value at the end of the cooling stage.

Aβ promotes microglial activation and apoptosis in the progression of AD by binding to TLR4.

Exploring the pathogenesis of AD and providing ideas for treatment can effectively improve the prognosis of AD.

Clinical value of a radiomics model based on machine learning for the prediction of prostate cancer.

Objective: Radiomics models have demonstrated good performance for the diagnosis and evaluation of prostate cancer (PCa). However, there are currently no validated imaging models that can predict PCa or clinically significant prostate cancer (csPCa). Therefore, we aimed to identify the best such models for the prediction of PCa and csPCa.

Driving factors of the distribution of microplastics in the surface soil of the typical uninhabited and habited areas in the Qinghai-Tibet plateau, China.

Microplastics (MPs) are widely detected in the soil of the Qinghai-Tibet Plateau with increasing economic activities. However, studies concerning the driving factors affecting the presence of these surface soil MPs for the typical regions with different geographic conditions are still lacking. Here we chose three representative regions (Ali, Yushu, and Haixi) from east to west across the plateau to investigate the distribution and further explore the contributing factors of surface soil MPs.

Operando Decoding Ion-Conductive Switch in Stimuli-Responsive Hydrogel by Nanodiamond-Based Quantum Sensing.

Thermal-responsive hydrogels are developed as ion-conductive switchs for energy storage devices, however, the molecule mechanism of switch on/off remains unclear.

Homo-Site Nucleation Growth of Twisted Bilayer MoS with Commensurate Angles.

Moiré superlattices, composed of two layers of transition metal dichalcogenides with a relative twist angle, provide a novel platform for exploring the correlated electronic phases and excitonic physics. Here, a gas-flow perturbation chemical vapor deposition (CVD) approach is demonstrated to directly grow MoS bilayer with versatile twist angles. It is found that the formation of twisted bilayer MoS homostructures sensitively depends on the gas-flow perturbation modes, correspondingly featuring the nucleation sites of the second layer at the same (homo-site) as or at the different (hetero-site) from that of the first layer.

DT-SCNN: dual-threshold spiking convolutional neural network with fewer operations and memory access for edge applications.

The spiking convolutional neural network (SCNN) is a kind of spiking neural network (SNN) with high accuracy for visual tasks and power efficiency on neuromorphic hardware, which is attractive for edge applications. However, it is challenging to implement SCNNs on resource-constrained edge devices because of the large number of convolutional operations and membrane potential (Vm) storage needed. Previous works have focused on timestep reduction, network pruning, and network quantization to realize SCNN implementation on edge devices.
