Ni(0) formation on carbon felt cathode triggers redox synergetic degradation of Ni-EDTA during electrochemical treatment for Ni-plating wastewater.

Ni organic complexes are widely used in industrial production, posing severe threats to the natural environment and human health. In this work, we found that Ni (0) formed by the decomplexation and reduction of typical Ni organic complexes (Ni-EDTA) on the surface of carbon felt cathode. The formed Ni(0) as a catalytic site generates atomic hydrogen (H•) with strong reductive reactivity via electron transfer.

Attention based multi-scale nested network for biomedical image segmentation.

Convolutional neural network-based methods have significantly enhanced the segmentation performance of biomedical images in recent years. Nevertheless, medical image segmentation presents a challenge marked by layout specificity, with limited variation between samples in medical datasets but significant variation within each individual sample. This aspect has been often overlooked by many models.

A simple and enzyme-free method for sensitive p53 analysis based on DNAzyme-mediated signal amplification.

There is an urgent demand for a simple yet extremely accurate biosensor to analyze tumorigenesis. Herein, we present a novel fluorescent and enzyme-free approach for detecting p53 gene cascading proximity ligation-mediated catalytic hairpin assembly and DNAzyme-assisted signal reaction. When the target p53 gene is present, the interaction between p53 and L1 and L2 chains initiates catalytic hairpin assembly and subsequently exposes DNAzyme in the P3 probe.

Enabling oral novel Taxanes-based Chemotherapy with Lipophilic prodrug Self-nanoemulsifying drug delivery system.

Larotaxel (LTX) and SB-T-1214 (SBT), two new synthetic experimental toxoids, have shown broad-spectrum antitumor activity, especially against tumors that are resistant to other drugs. However, their poor solubility, membrane permeability, and first-pass effect limits their use in oral administration. We designed and synthesized two long-chain triglyceride-mimic prodrugs of LTX (LTXSSTG) and SBT (SBTSSTG), which are bridged by disulfide bonds and efficiently incorporated them into Self-nanoemulsifying drug delivery system (SNEDDS).

Melatonin alleviates LPS-induced depression-like behavior in mice by inhibiting ferroptosis by regulating RNA methylation-mediated SIRT6/Nrf2/HO-1 pathway.

Purpose: The objective of this study is to investigate the impact of ferroptosis on depression and elucidate the molecular mechanism underlying melatonin's inhibitory effect on ferroptosis in the treatment of depression.

Methods: In this study, a depression-like behavior model was induced in mice using LPS, and the effect of melatonin on depression-like behavior was evaluated through behavioral experiments (such as forced swimming test (FST) and sucrose preference test (SPT)). Additionally, molecular biological techniques (including real-time fluorescence quantitative PCR, Western blotting, immunoprecipitation) were employed to detect the expression levels and interactions of METTL3, SIRT6 and ferroptosis-related genes in mouse brain tissue.

An integral assessment of the impact of diet and manure management on whole-farm greenhouse gas and nitrogen emissions in dairy cattle production systems using process-based models.

Feed management decisions are crucial in mitigating greenhouse gas (GHG) and nitrogen (N) emissions from ruminant farming systems. However, assessing the downstream impact of diet on emissions in dairy production systems is complex, due to the multifunctional relationships between a variety of distinct but interconnected sources such as animals, housing, manure storage, and soil. Therefore, there is a need for an integral assessment of the direct and indirect GHG and N emissions that considers the underlying processes of carbon (C), N and their drivers within the system.

Fast degradation of vinyl chloride by green rust and nitrogen-doped graphene.

Carbonaceous materials catalyze reductive dechlorination of chlorinated ethylenes (CEs) by iron(II) materials providing a new approach for the remediation of CE polluted groundwater. While most CEs are reduced via β-elimination, vinyl chloride (VC), the most toxic and recalcitrant CE, degrades by hydrogenolysis. The significance of carbon catalysts for reduction of VC is well documented for iron(0) systems, but hardly investigated with iron(II) materials as reductants.

In this study, high-purity Fe(OH) was synthesized and tested for its activity in the degradation of carbon tetrachloride (CT).

A Modular Event-Triggered Containment Control Scheme for Nonlinear Heterogeneous Multiagent Systems With Unknown Leaders.

This article addresses the containment control problem in multiagent systems with nonlinear heterogeneous followers and multiple unknown leaders whose dynamics are exclusively known to their neighbors. The primary goal is to ensure the convergence of each follower to the dynamic convex hull spanned by the leaders under the constraints of limited communication resources. To achieve this, this article introduces a modular event-triggered containment control scheme with three modules.
