Summary: A pH-responsive drug carrier was developed for controllable drug release in the gastric environment by grafting hydroxyapatite into a chitosan/nano-clay matrix. The co-precipitation method led to the penetration of hydroxyapatite nanoparticles inside the matrix, reducing drug release rate. The nanocomposite showed high sensitivity to pH and significantly decreased drug release rate in both gastric and intestinal environments.

Summary: The aim of this study was to develop an economical and effective catalyst for wastewater remediation using the Fenton oxidation process. Fe3O4-montmorillonite alginate (FeMA) composite beads were synthesized and evaluated for the degradation of the antibiotic ofloxacin (OFL) in water. The FeMA composite beads showed higher surface area, porosity, and thermal stability compared to pristine alginate beads. The results demonstrated that FeMA composite beads can be a promising material for wastewater remediation via the Fenton oxidation process.

Summary: The overuse of antibiotics can lead to the development of resistance to targeted bacteria. A controlled release system, such as the nanocomposite films prepared in this study, can provide a solution for achieving higher drug efficiency without overdosing and drug resistance. The films, made from chitosan reinforced with cellulose nanofibrils, showed promising properties for antibiotic release. The content of nanofibers in the film formulation affected the swelling capacity, stiffness, and tensile strength of the films, as well as the release rate of vancomycin, suggesting the potential application of these films for pharmaceutical purposes.

Summary: In this study, a pH-sensitive magnetic hydrogel nanocomposite was synthesized for extended release of methotrexate (MTX). The nanocomposite exhibited less burst release in the gastric and intestinal fluid, leading to the intact beads passing through the stomach and releasing the drug at a slower rate in the intestine. In breast cancer cells, the nanocomposite showed anti-proliferative and apoptotic effects.

Summary: The rapid development of antibiotic resistance is a major threat to public health. Nanomaterials, particularly ZnO nanocrystal clusters, have shown excellent bactericidal ability. The clusters, formed through a green structure-tuning synthesis process, exhibited superior performance in killing Escherichia coli and Staphylococcus aureus. The antibacterial action is attributed to increased contact with bacteria, the release of small ZnO nanoparticles, and the generation of reactive oxygen species, which damage the bacterial cell membrane. In addition, the attachment of phenolic compounds from olive leaf extract enhances the antibacterial activity of ZnO clusters. This study presents a feasible and clean strategy for improving the structure-bioactivity relationship of ZnO and highlights the potential of ZnO clusters in antibacterial applications due to their excellent performance and green fabrication method.

Summary: This study aimed to evaluate the bleeding risk of low-dose aspirin treatment in high-risk pregnant women and the incidence of postpartum hemorrhage (PPH) according to maternal characteristics. The results showed that a dosage of 100 mg aspirin per day did not increase the risk of bleeding or PPH, regardless of maternal characteristics. However, in the aspirin group, there was a significant correlation between BMI and PPH.

Summary: The study analyzed the agricultural water footprint (AWF) and its spatiotemporal characteristics in the Hexi corridor, Northwest of China from 2002 to 2017 using the water footprint theory. The AWF increased during the study period, with a rapid increase in the water footprint of cash crops and a slower and stable increase in the water footprint of grain production. There were significant differences in the water footprint of agricultural products among the counties in the Hexi corridor. The study also explored the relationship between AWF and GDP, population, grain yield, fertilization, and urbanization rate, and found that economic growth, grain yield, and fertilization had a significant positive relationship with AWF.

Summary: In this study, functional Zn-based mixed metal oxides (Zn-MMOs) were fabricated using a ZnO-assisted hydrothermal coprecipitation method with spent metal ions from acid-leached clay for antibiotic and microorganism removal from water. The results demonstrated that the composition, micro-structure, adsorption, and antibacterial activity of Zn-MMOs were influenced by the amount of ZnO added. Zn-MMOs showed high adsorption capabilities for tetracycline and chlortetracycline, as well as comparable antibacterial activity to commercial ZnO, making them effective for eliminating microbial contaminants in water. This work offers a collaborative solution for waste resource utilization and wastewater pollution treatment, contributing to the promotion of green economy and sustainable development.

Summary: By modifying polydopamine (PDA) on the surface of molybdenum disulfide (MoS2), small-sized copper nanoparticles were grown uniformly to form MoS2/PDA@Cu nanozyme. This nanozyme exhibited excellent peroxidase-like activity and antibacterial properties, showing a more pronounced inhibitory effect on bacterial growth with the addition of H2O2. The maximum reaction rate (V-max) of the MoS2/PDA@Cu nanozyme is significantly higher than that of horseradish peroxidase (HRP), and it also demonstrated excellent biocompatibility, hemocompatibility, and potential anticancer properties.
