Summary: The novel nanocapsule-embedded hydrogel dressing (MCNG-H), formed by crosslinking magnolol-grafted-chitosan hydrochloride (CSCl-MAG) with genipin, shows sustained antibacterial and antioxidant properties. MCNG-H exhibits good swelling properties and biocompatibility, with the combination of CSM-H and MCNGs effectively inhibiting bacteria and eliminating reactive oxygen species (ROS). The pH-responsive release of loaded MAG in MCNG-H ensures sustained release and long-term antibacterial and anti-oxidant activities. In a splinted excisional dermal wound model, MCNG-H significantly accelerates wound healing, making it a promising dressing for infected wounds.

Summary: Antimicrobial hydroxybenzaldehyde derivatives were immobilized on chitosan films using reversible Schiff bases. The different abilities of the aldehydes to form Schiff bases with chitosan were demonstrated through spectroscopy and elemental analysis. Chitosan films modified with Schiff bases of aldehydes exhibited antimicrobial properties against E. coli in mild acidic environments. The effectiveness of the films depended on the reversibility of imine bonds and the release of the aldehydes, which was enhanced in mildly acidic solutions. The structure of the covalently bonded aldehyde also influenced the reversibility of the imine bonds.

Summary: This study conducted a (15)N tracing study to examine the impacts of long-term nitrogen fertilization on gross N transformation rates in soil. The results showed that organic or chemical N applications significantly stimulated N mineralization and autotrophic nitrification rates, leading to increased crop yields. However, the immobilization of mineral N decreased after long-term N applications, and N2O emissions also increased. Therefore, a combination of organic and chemical N fertilizers is recommended for climate-smart agricultural practices.

Summary: This study used natural language processing to create a cohort of nonalcoholic fatty liver disease (NAFLD) patients in primary care. The study assessed advanced fibrosis risk using the Fibrosis-4 Index (FIB-4) and NAFLD Fibrosis Score (NFS), and evaluated the agreement between these risk scores. The study found that many patients had elevated FIB-4 and NFS risk scores, and these risk categories were often in disagreement. The choice between FIB-4 and NFS for fibrosis risk assessment can impact clinical decision-making and may contribute to disparities of care.

Summary: In this article, we propose a regression model for partially observed dynamic tensors, characterized by low-rankness, sparsity, and fusion structures on the regression coefficient tensor. We develop an efficient nonconvex alternating updating algorithm and derive the error bounds of the estimators. Our approach differs significantly from existing tensor completion or tensor response regression solutions. It is illustrated using simulations and real applications in neuroimaging dementia study and digital advertising study.

Summary: A novel n-i heterostructure strategy using CeO2 and amorphous alumina has been proposed to develop composite electrolytes for low-temperature solid oxide fuel cells (LT-SOFCs). The CeO2/a-Al2O3 electrolyte exhibits high ionic conductivity and fuel cell performance due to the suppressing effect on electron conduction and the promotion of ion transport caused by the potential energy barrier and thermoelectric effect at the heterointerface. This study presents a practical electrolyte design and opens frontiers in developing high-efficiency electrolytes for LT-SOFCs using insulating materials.

Summary: This study reveals that high-temperature shock can convert spent graphite into defect-rich recycled graphite, which is ideal for high-rate anodes and exhibits higher charging capacity than commercial graphite. The recovery of layered structure and remaining defects during ultrafast heating and cooling process reduce strain energy, accelerate phase transition, and improve Li+ diffusion in recycled graphite. This research provides a facile strategy to guide the re-graphitization of spent graphite and design high-performance battery electrode materials through defect engineering at the atomic level.

Summary: The impact of dietary inflammatory potential on serum cytokine concentrations in second and third trimesters of Chinese pregnant women was investigated. 175 pregnant women were included in the study. The dietary inflammatory index (DII) was calculated and serum levels of various cytokines were measured. The results showed a U-shaped association between DII score and cytokine levels in the third trimester, and changes in DII scores between the second and third trimesters were correlated with cytokine levels in the third trimester.

Summary: Metal halide perovskites, such as methylammonium lead bromide, have attracted attention for their photoelectric properties. In this study, methylammonium lead bromide magic-sized clusters (MSCs) were synthesized using ligand-assisted reprecipitation (LARP) and heated LARP (HLARP) methods. The HLARP synthesis resulted in improved stability and higher quantum yield of the MSCs. The addition of paraffin further enhanced the stability of the MSCs in both liquid and solid states.
