Bacteria-activated macrophage membrane coated ROS-responsive nanoparticle for targeted delivery of antibiotics to infected wounds.

Bacterial infections and antibiotic resistance represent significant global public health challenges, necessitating the development of innovative antibacterial agents with targeted delivery capabilities. Our study utilized macrophages' natural ability to recognize bacteria and the increased reactive oxygen species (ROS) at infection sites to develop a novel nanoparticle for targeted delivery and controlled release. We prepared bacteria-activated macrophage membranes triggered by Staphylococcus aureus (Sa-MMs), which showed significantly higher expression of Toll-like receptors (TLRs), compared to normal macrophage membranes (MMs).

Isolation and investigation on lactic acid bacteria for potential probiotic properties from cat feces.

Background: Probiotics, which are beneficial to the host, have been shown to benefit the health of cats. Lactic acid bacteria (LAB) are commonly used probiotics, but most strains used for cats are not derived from cats, leading to reduced efficacy and poor adaptation to cats. The objective was to identify LAB with promising probiotic potential specific to cats.

However, it is indeed a challenge to strike a balance between accuracy and efficiency at the same time.

Regorafenib Combination Therapy in Advanced Hepatocellular Carcinoma: With or Without Transarterial Chemoembolization.

Introduction: The effectiveness and tolerability of triple therapy, which combines regorafenib, a programmed death 1 (PD-1) inhibitor, and transarterial chemoembolization (TACE), were compared to dual therapy consisting of regorafenib and a PD-1 inhibitor in patients with advanced hepatocellular carcinoma (HCC).

Methods: A retrospective analysis was conducted on patients with advanced HCC who underwent second-line therapy from March 2019 to June 2022 at multiple centers. Patients were stratified into two groups: dual therapy (comprising regorafenib and a PD-1 inhibitor) and triple therapy (consisting of regorafenib, a PD-1 inhibitor, and TACE).

Impact of Temperature and Substrate Type on the Optical and Structural Properties of AlN Epilayers: A Cross-Sectional Analysis Using Advanced Characterization Techniques.

AlN, with its ultra-wide bandgap, is highly attractive for modern applications in deep ultraviolet light-emitting diodes and electronic devices. In this study, the surface and cross-sectional properties of AlN films grown on flat and nano-patterned sapphire substrates are characterized by a variety of techniques, including photoluminescence spectroscopy, high-resolution X-ray diffraction, X-ray photoelectron spectroscopy, ultraviolet photoelectron spectroscopy, and Raman spectroscopy. The results indicate that different sapphire substrates have minimal impact on the photoluminescence spectrum of the epitaxial films.

Prognostic importance of the Scottish inflammatory prognostic score in patients with hepatocellular carcinoma after hepatectomy: a retrospective cohort study.

Background: The Scottish Inflammatory Prognostic Score (SIPS), an innovative scoring system, has emerged as a promising biomarker for predicting patient outcomes following cancer therapy. This study aimed to evaluate the value of SIPS as a prognostic indicator following hepatectomy in patients with hepatocellular carcinoma (HCC).

Methods: This retrospective study included 693 HCC patients who underwent hepatectomy.

Evidence of Quasi-Na Metallic Clusters in Sodium Ion Batteries through In Situ X-Ray Diffraction.

Carbonaceous materials have been considered the most promising anode in sodium-ion batteries (SIBs) due to their low cost, good electrical conductivity, and structural stability. The main challenge of carbonaceous anodes prior to their commercialization is low initial coulomb efficiencies, derived from a lack of an efficient technique to reveal a fundamental comprehension of sodium storage mechanisms. Here, the direct observation of quasi-Na metallic clusters in carbonaceous anodes during cycling through in situ XRD is reported.

Online SFE-SFC-MS/MS analysis of pyraclostrobin and chiral mefentrifluconazole residues in mango and mango juice.

This study established an on-line SFE-SFC-MS/MS method for the determination of mefentrifluconazole (MFZ) enantiomers and pyraclostrobin (PY) in mango and mango juice. Key parameters of SFC separation and SFE extraction have been optimized for high efficiency, sensitivity, and environmental friendliness. Enthalpy controlled enantioseparations of MFZ were recognized by thermodynamic analysis.

Inter-Skeleton Conductive Routes Tuning Multifunctional Conductive Foam for Electromagnetic Interference Shielding, Sensing and Thermal Management.

Conductive polymer foam (CPF) with excellent compressibility and variable resistance has promising applications in electromagnetic interference (EMI) shielding and other integrated functions for wearable electronics. However, its insufficient change amplitude of resistance with compressive strain generally leads to a degradation of shielding performance during deformation. Here, an innovative loading strategy of conductive materials on polymer foam is proposed to significantly increase the contact probability and contact area of conductive components under compression.

Building a Chinese ancient architecture multimodal dataset combining image, annotation and style-model.

In this rapidly evolving era of multimodal generation, diffusion models exhibit impressive generative capabilities, significantly enhancing the realm of creative image synthesis by intricately textual prompts. Yet, their effectiveness is limited in certain niche sectors, like depicting Chinese ancient architecture. This limitation is primarily due to the insufficient data that fails to encompass the unique architectural features and corresponding text information.

Feasibility of double nitrite supply through partial nitrification and partial denitrification driven by sludge fermentation.

Challenges in obtaining stable nitrite have impeded the use of anammox in municipal wastewater treatment. This study explored the feasibility of using sludge fermentation products as carbon source and selective nitrification inhibitor to supply nitrite via partial nitrification (PN) and partial denitrification (PD). PD was initiated within 15 days, achieving nitrite transformation rate of over 90 % with a carbon/nitrogen ratio of 3 and a reaction time of 0.

Making an inverted Keggin ion lacunary.

The century-old inverted Keggin ion has been revisited in an effort to unleash its potential in the structural engineering and functional development of polyoxomolybdates (POMos). Over the past hundred years, attempts to program the metal-oxo scaffold of inverted Keggins have been conducted continually but without any success. In this work, a structurally inert, inverted Keggin-type POMo could finally be altered by means of a binary heterogroup-templated approach, resulting in the successful isolation of two lacunary species.

Extrapolation of Upadacitinib Efficacy in Juvenile Idiopathic Arthritis Leveraging Pharmacokinetics, Exposure-Response Models, and Real-World Patient Data.

Juvenile idiopathic arthritis (JIA) is the most prevalent pediatric rheumatic disease. While disease-modifying antirheumatic drugs (DMARDs), especially biologics, have greatly transformed the management of JIA, there remain some unmet medical needs that require new treatment options. The objective of this work was to describe and apply a modeling and simulation approach to extrapolate upadacitinib efficacy from the adult diseases, rheumatoid arthritis (RA) and psoriatic arthritis (PsA), to their respective pediatric diseases, polyarticular course JIA (pcJIA), and juvenile PsA (JPsA).

The effect of anionic emulsifiers' diversity and manufacturing processes on the stability and mechanical properties of the water-based epoxy-emulsified asphalt.

Emulsified asphalt mixtures' cold mix and paving features facilitate asphalt pavements in fulfilling dual-carbon and energy-saving demands. Anionic emulsifiers can enhance emulsion stability, ensure uniform dispersion of oil and water, possess good decompression viscosity, thickening, and lubricating properties, and maintain good stability under acidic conditions. Nevertheless, anionic emulsified asphalt is restricted in engineering applications due to problems like its storage stability.
