In this study, Fe, N co-doped biochar (Fe@N co-doped BC) was synthesized by the carbonization-pyrolysis method and used as a carbocatalyst to activate peroxymonosulfate (PMS) for sulfamethoxazole (SMX) removal. In the Fe@N co-doped BC/PMS system, the degradation efficiency of SMX (10.0 mg·L) was 90.

Snhg14/miR-181a-5p axis-mediated "M1" macrophages aggravate LPS-induced myocardial cell injury.

An increasing number of studies have suggested that macrophages participate in sepsis-induced myocardial injury. Our study highlights the function and mechanism of the lncRNA Snhg14 in "M1" polarized macrophage-mediated myocardial cell damage. Lipopolysaccharide (LPS) was used to treat H9c2 cells to construct an myocardial injury model.

Role and Mechanism of Lamellar Derived Growth Factor /AKT Pathway in Ventricular Remodeling Induced by Pressure Overload.

This study aimed to investigate the role and underlying mechanisms of the platelet-derived growth factor (PDGF)/protein kinase B (AKT) signaling pathway in pressure overload-induced ventricular remodeling. Ventricular remodeling, a critical pathological process in heart failure, is commonly triggered by pressure overload. While PDGF is known to promote cell proliferation and growth, the AKT pathway is crucial for cell growth, survival, and metabolism.

Optimizing health risk assessment for soil trace metals under low-precision sampling conditions: A case study of agricultural soil.

Cost limitations often lead to the adoption of lower precision grids for soil sampling in large-scale areas, potentially causing deviations in the observed trace metal (TM) concentrations from their true values. Therefore, in this study, an enhanced Health Risk Assessment (HRA) model was developed by combining Monte Carlo simulation (MCS) and Empirical Bayesian kriging (EBK), aiming to improve the accuracy of health risk assessment under low-precision sampling conditions. The results showed that the increased sampling scale led to an overestimation of the non-carcinogenic risk for children, resulting in potential risks (the maximum Hazard index value was 1.

Methods: The subjects of this study were 100 patients who were being treated at Li Huili Hospital from December, 2022 to December, 2023 for persistent subjective vertigo. With 50 instances in each category, individuals with chronic subjective dizziness were randomly assigned to the shallow acupuncture control category & the regular acupuncture category.

Bias-free driven ion assisted photoelectrochemical system for sustainable wastewater treatment.

Photoelectrochemical (PEC) systems have emerged as a prominent renewable energy-based technology for wastewater treatment, offering sustainable advantages such as eliminating dependence on fossil fuels or grid electricity compared to traditional electrochemical treatment methods. However, previous PEC systems often overlook the potential of ions present in wastewater as an alternative to externally applied bias voltage for enhancing carrier separation efficiency. Here we report a bias-free driven ion assisted photoelectrochemical (IAPEC) system by integration of an electron-ion acceptor cathode, which leverages its fast ion-electron coupling capability to significantly enhance the separation of electrons and holes at the photoanode.

Long Non-Coding RNA Dancr Affects Myocardial Fibrosis in Atrial Fibrillation Mice via the MicroRNA-146b-5p/Smad5 Axis.

Objectives: Atrial fibrillation (AF) is the most frequent arrhythmia, and myocardial fibrosis (MF) has a close association with atrial remodeling and leads to AF. This study aimed to explore the function of the long non-coding RNA (lncRNA) differentiation antagonizing non-protein coding RNA (Dancr)/microRNA (miR)-146b-5p/Smad5 axis on MF in AF mice.

Methods: AF mouse models were established.

Drug-Coated Balloons for De Novo Coronary Artery Lesions: A Meta-Analysis of Randomized Clinical Trials.

Purpose: Through meta-analysis, we aimed to assess the efficacy and safety of drug-coated balloons (DCB), compared with drug-eluting stents (DES) or uncoated devices, in the treatment of de novo coronary lesions.

Materials And Methods: Only randomized controlled trials were included. The primary outcomes were late lumen loss (LLL), target lesion revascularization (TLR), and major adverse cardiac events (MACEs).

Reliability Study of Wood-Plastic Composites Based on Probabilistic Finite Elements.

In order to further expand the application field of wood-plastic composites, it is necessary to study the reliability of this material in practical applications. Therefore, this work takes the maximum stress theory as the failure criterion and uses the finite element method to simulate the reliability of the WPC specimen. Based on the simulation results, the relationship between reliability and random variables such as geometric parameters and external load is analyzed.

The Effectiveness Comparison of Different Acupuncture-Related Therapies on Knee Osteoarthritis: A Meta-Analysis.

Objective: This meta-analysis aims to assess the efficacy of acupuncture-related therapy on knee osteoarthritis (KOA) patients.

Method: We searched PubMed, Embase, and CNKI databases to screen eligible trials between 2017 and 2022. All trials that used acupuncture/moxibustion of KOA patients were included.

Luminescent europium(III)-organic framework for visual and on-site detection of hydrogen peroxide via a tablet computer.

A luminescent metal-organic framework of type Eu(III)-MOF has been fabricated for visual and on-site fluorometric determination of hydrogen peroxide (HO) via a tablet computer. The maximum excitation and emission peaks of type Eu(III)-MOF were found at λex = 290 nm and λem = 615 nm, respectively. The average length of Eu-MOF is 1.

Pollution patterns and characteristics of perfluorinated compounds in surface water adjacent potential industrial emission categories of Shanghai, China.

Perfluorinated compounds (PFCs) have received increasing attention worldwide recently because of potential risk to aquatic environment and living organisms. Herein, occurrence and spatial distributions of 17 selected PFCs were investigated in surface water adjacent to potential industrial emission categories in Shanghai. The results showed the distributions of PFCs in the ambient rivers were greatly affected by those industrial sources.

Study on polymer fibers doped with phosphorescent Re(I) complex via electrospinning: synthetic strategy, structure, morphology and photophysical features.

In the following paper, a Re(I) complex with electron-withdrawing oxadiazole group in its diamine ligand (denoted as N-N) was synthesized. Its single crystal structure analysis confirmed the successful synthesis of both ligand and complex. The central Re(I) ion localized in a traditional octahedral coordination environment.

[Rapid determination of fatty acids in Ranunculus ternatus Thunb by microwave-ultrasonic synergistic one-step extraction-derivatization and gas chromatography-mass spectrometry].

A rapid and simple microwave-ultrasonic synergistic one-step extraction-derivatization (MUED) method and gas chromatography-mass spectrometry was established for the determination of low content fatty acids (FAs) profile in Ranunculus ternatus Thunb. The critical experimental parameters for MUED method were optimized with response surface methodology by taking the chromatographic peak areas of total FAs as a major response index. The best technological parameters were determined as 5.

TWEAK/Fn14 promotes the proliferation and collagen synthesis of rat cardiac fibroblasts via the NF-кB pathway.

We wished to elucidate a potential role of the tumor necrosis factor-like weak inducer of apoptosis (TWEAK)/fibroblast growth factor-inducible molecule 14 (Fn14) axis in myocardial fibrosis. Stimulation of neonatal rat cardiac fibroblasts (CFs) with TWEAK could increase CFs numbers and collagen synthesis. Conversely, when CFs were pretreated with siRNA against Fn14, induction of cell proliferation and collagen synthesis by TWEAK were inhibited.
