High efficiency enrichment and trace analysis of triazine herbicide residues are crucial for ensuring environmental and food safety. Herein, a series of magnetic hyper-crosslinked polymers (CD-gs-MHCPs) were synthesized with different crosslinkers, which might possess different pore structure and surface area, so they might dispay variable adsorption performance. CD-gs-MHCP2 with dichloroxylene as crosslinker delivered superior adsorption ability for triazine herbicides (THs). The synergistic effect of hydrogen bonds, hydrophobic interaction, π-π stacking interaction and pore adsorption were proved to be the main adsorption mechanism. Combined CD-gs-MHCP2 based magnetic solid-phase extraction (MSPE) with high-performance liquid chromatography, the quantitative analysis of THs in river water and vegetable samples (zucchini, pakchoi) was achieved. Under the optimal conditions, the enrichment factors for three different samples ranged from 94 to 244 and low detection limit (S/N = 3) of the four THs were obtained from 0.05 to 0.15 ng mL −1 for river water and 0.31–3.10 ng g −1 for vegetable samples. The method recoveries were in the range of 86.2 %–120 % with relative standard deviations lower than 7.4 %. This work not only offers a new strategy for fabrication β-CD-based HCPs, but also provided a practical and effective method for efficient isolation and sensitive detection of trace THs residues in complex samples.

The incidence of acetaminophen-induced liver injury has increased, but effective prevention methods are limited. Although luteolin has hepatoprotective activity, its low solubility and bioavailability limit its applications. Cyclodextrin metal-organic frameworks (CD-MOFs) possess 3D-network structures and large inner cavities, which make them excellent carriers of poorly soluble drugs. In this study, we used CD-MOFs as carriers to improve the dissolution of luteolin and assessed their antioxidant activity, bioavailability, and hepatoprotective effects. Luteolin was loaded into β-CD-MOF, γ-CD-MOF, β-CD, and γ-CD, and characterized by powder X-ray diffractometry (PXRD) and thermogravimetric analysis (TGA). Our results showed that luteolin-β-CD-MOF was the most stable. The main driving forces were hydrogen bonds and van der Waals forces, as determined by molecular simulation. The loading capacity of luteolin-β-CD-MOF was 14.67 wt%. Compared to raw luteolin, luteolin-β-CD-MOF exhibited a 4.50-fold increase in dissolution and increased antioxidant activity in vitro . Luteolin-β-CD-MOF increased the bioavailability of luteolin by approximately 4.04- and 11.07-fold in healthy rats and liver injured rats induced by acetaminophen in vivo , respectively. As determined by biochemical analysis, luteolin-β-CD-MOF exhibited a better hepatoprotective effect than raw luteolin in rats with acetaminophen-induced liver injury. This study provides a new approach for preventing acetaminophen-mediated liver damage.

This study developed nanostructured lipid carriers (NLCs) using edible beeswax and flaxseed oil to encapsulate β-sitosterol. Structural analysis revealed the formation of a less ordered lipid matrix with reduced crystallinity compared to pure beeswax, contributing to a high encapsulation efficiency of 92 %. Optimal formulation (beeswax: flaxseed oil 3:2, Tween 80: Polyglycerol fatty acid(PGE) 4:1 totaling 7 % emulsifier) and processing parameters (10 min homogenization, 200 W ultrasonic power for 4 min) yielded stable nanoparticles maintaining physical stability for 40 days across varying pH and temperature. In vitro digestion demonstrated that the NLCs effectively protected β-sitosterol from gastric degradation and enabled controlled intestinal release, achieving significantly higher bioaccessibility (43.9 %) compared to free β-sitosterol (12.1 %). These results highlight beeswax-flaxseed oil NLCs as a promising delivery system for enhancing the bioaccessibility of hydrophobic bioactive in functional foods.

Nanofiltration (NF) membrane could be used for recovering antibiotics in the waste effluents from bacterial and fungal fermentation and other processes. By doping large hydroxyl-rich monomers with rigid structures into the selective layers of NF membrane, the selectivity between antibiotics and monovalent salts can be further improved by enhancing the pore size and hydrophilicity of the membrane, resulting in effective recovery of antibiotics. The present work fabricated NF membranes through interfacial polymerization between trimesoyl chloride (TMC) and a modified aqueous-phase piperazine solution containing the anionic cyclodextrin derivative sulfobutyl-β-cyclodextrin as a hydrophilic dopant. The addition of SBE-β-CD has the potential to enhance membrane pore size and hydrophilicity to improve the selectivity of the separated layer. The optimum membrane exhibited water flux of 30.72 L·m −2 ·h −1 ·bar −1 , rejection of 97.05 % and 84.93 % respectively to antibiotics tetracycline hydrochloride and amoxicillin and low rejection of 3.39 % to NaCl. Hence, the membrane shows high selectivity between antibiotics and monovalent salt. The membrane also has a reasonable stability during a 40 h test, which shows potential in application of antibiotic recovery.

This study investigates the antioxidant interactions of γ-tocopherol, β-sitosterol, and ellagic acid in iron walnut oil within ethanol and ethyl acetate, assessing their impact on oxidative stability. In ethanol, γ-tocopherol and ellagic acid display initial synergistic effects, enhancing free radical scavenging beyond their individual capabilities. Conversely, γ-tocopherol and β-sitosterol show antagonistic effects, reducing their combined scavenging abilities. Kinetic analysis indicates ellagic acid's robust scavenging, generally outperforming combinations of antioxidants. Fourier-transform infrared spectroscopy revealed that solvent polarity significantly impacts hydrogen bonding interactions. Ethanol, with its higher polarity, promoted more extensive hydrogen bonding compared to ethyl acetate, which imposed constraints on such interactions due to its lower polarity. Notably, despite its poor solubility in ethyl acetate, ellagic acid exhibits enhanced synergy with γ-tocopherol, likely via electron transfer. These findings underscore the intricate dynamics of antioxidant interactions, further emphasizing the pivotal role of solvent polarity in modulating these interactions. These results indicated that solvent properties significantly influence antioxidant behavior, yet they also introduce novel insights specific to the iron walnut oil system.

The development of artificial biomaterials that simulate the extracellular matrix of bone tissue is a promising strategy for bone regeneration. Hydrogel has become a feasible alternative, yet its lack of biological activity still needs to be improved. Herein, a piezoelectric composite hydrogel (TBP) based on tripolyglycerol monostearate (TM) and loaded with barium titanate (BTO) nanoparticles through hydrogen bonding provided by polydopamine has been developed to promote osteogenesis. In vitro , TBP exhibits excellent injectability, shape adaptability and biodegradability, ensuring the feasibility of its biological applications. Moreover, by virtue of the piezoelectric conversion capability of BTO, TBP has the response ability to low-intensity pulsed ultrasound (LIPUS) and can generate local electrical signals. Meanwhile, TBP performs outstandingly in promoting the proliferation, migration, adhesion and osteogenic differentiation of MC-3 T3-E1 cells. More importantly, TBP combined with LIPUS stimulation can regulate mitochondrial oxidative phosphorylation (OXPHOS) through the AKT/GSK3β/β-catenin signaling cascade, thereby accelerating osteogenesis. In vivo , the application of TBP hydrogel to the bone defect site of rats, combined with LIPUS stimulation, shows satisfactory effects in promoting bone regeneration. To sum up, this piezoelectric composite hydrogel is expected to become a promising candidate for bone tissue engineering.

In this work, we developed a matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) method to directly analyze human whole blood samples. 1.0 µL of whole blood samples and 1.0 µL of optimized organic matrix were directly loaded onto the sample plates for MALDI-TOF-MS detection. A total of 59 whole blood samples were investigated in this work, including 23 healthy control samples, 28 α-globin gene triplication carriers with α-chain repetition, and eight deletional hemoglobin H disease (HbH) patients with α-chain deficiency. Human hemoglobin (Hb) chains with high signal-to-noise were directly observed. It is found that there is a change in signal ratios of α/β-chains of Hb from blood samples in thalassemia subtypes by comparing the ratios obtained from healthy blood samples. Analytical variability ( n = 6) of signal ratios of α/β-chains was found to be 3.33%–12.86% (intra-day), 4.02%–13.39% (inter-day), and 6.41%–15.32% (inter-laboratory), respectively. Furthermore, the results were validated using different MALDI-TOF MS approaches. Our results suggest that α/β-chains ratios of Hb could be an indicator for investigating thalassemia by MALDI-TOF-MS.

Zinc corrosion, hydrogen evolution reaction, uneven deposition, and dendrite growth on the zinc anodes are the key factors restraining the electrochemical performance and cycling stability of the aqueous zinc-ion batteries. In this study, learned from the synial membrane, a tiny amount of natural amino acid β-alanine (β-Ala, 0.089 wt %) was introduced as the additive in ZnSO4 electrolyte for strengthening the kinetics of the zinc anode as well as enhancing the performance of zinc ions batteries. A number of modern surface techniques and surface electrochemical analyses were employed to reveal the fundamental reasons for the strengthened zinc anode by β-Ala in ZnSO4 electrolyte. The results show that β-Ala could be adsorbed on zinc electrode surface through intermolecular chelation, which might regulate the chemical environments of the electrolyte and promote uniform deposition of zinc ions. Hence, the β-Ala adsorption film on zinc electrode could suppress the hydrogen evolution reaction and the formation of zinc dendrites, thereby significantly improving the deposition/stripping process of the zinc anode. In particular, the strong hydrogen bonding could restrain the migration of H2O molecules approaching the zinc anode surface, preventing the invasion of water to the zinc electrode surface. Therefore, the addition of dilute β-Ala in the ZnSO4 electrolyte might remarkably prolong the life span of Zn||Zn symmetric batteries to 5000 h under 1 mA cm–2 and 1 mAh cm–2, and to 450 h under 5 mA cm–2 and 3 mAh cm–2 at 298 K, which is much longer than the zinc–zinc symmetric cells including the bare ZnSO4 electrolyte (only 95 h at 5 mA cm–2 and 3 mAh cm–2, and 200 h at 1 mA cm–2 and 1 mAh cm–2). Furthermore, β-Ala was found to significantly improve the cycling stability of Zn||Cu asymmetric cells and Zn||V2O5 full cells. This study provides an effective method for engineering electrolytes to inspire rechargeable zinc-ion batteries by selecting ideal natural biomolecules as the electrolyte additives.

The μ-opioid receptor-biased agonist theory holds that G io protein signaling mediates the analgesic effect of opioids and the related side effects via the β-arrestin2 signaling pathway. A series of μ-opioid-biased agonists have been developed in accordance with this theory, and the FDA has approved TRV130 (as a representative of biased agonists) for marketing. However, several reports have raised the issue of opioid side effects associated with the use of agonists. In this study, five permeable peptides were designed to emulate 11 S/T phosphorylation sites at the μ-opioid receptor (MOR) carboxyl-terminal. In vitro experiments were performed to detect the activation level of G proteins from the cAMP inhibition assay and the β-arrestin2 recruitment by the BRET assay. Designed peptides might effectively interfere with the activation of the G io and β-arrestin2 pathways when combined with morphine. The resulting morphine-induced tolerance, respiratory inhibition, and constipation in mice showed that the β-arrestin2 pathway was responsible for morphine tolerance while the G io signaling pathway was involved with respiratory depression and constipation and that these side effects were significantly related to phosphorylation sites S363 and T370. This study may provide new directions for the development of safer and more effective opioid analgesics , and the designed peptides may be an effective tool for exploring the mechanism by which μ-opioid receptors function, with the potential of reducing the side effects that are associated with clinical opioid treatment.

The present work effectively achieved the production of a self-supporting electrode with high efficiency. The process involves incorporating nickel and molybdenum carbide (Mo 2 C) phases within the channels of wood through high-temperature calcination at the nanoscale. The obtained carbonized wood (CW) possesses low tortuosity and three-dimensional vertical channels, providing an excellent substrate for the preparation of Ni-Mo 2 C/N-CW electrodes. Mo 2 C is well known for its considerable potential as a non-precious metal electrocatalyst with enhanced catalytic activity. The successful doping of nickel and nitrogen into molybdenum carbide not only promotes the formation of β-Mo 2 C, but also improves the electron transfer rate and mass diffusion pathway. Consequently, the Ni-Mo 2 C/N-CW electrode exhibits excellent performance in the hydrogen and oxygen evolution reactions (HER and OER, respectively). Only voltages of 89 and 253 mV are required to achieve a current density of 10 mA cm −2 , respectively. When the Ni-Mo 2 C/N-CW catalyst is used as both cathode and anode during hydrolysis, current densities of 10 and 100 mA cm −2 can be achieved with excellent durability and stability at voltages of 1.56 and 1.72 V, respectively. The distinctive porous structure of the wood substrate is of crucial importance for promoting the adsorption and dissociation of water molecules, enhancing the catalytic performance. In addition, the present material exhibits advantageous characteristics, including a high specific surface area and a significant number of adsorption sites, making it a very promising candidate for applications involving the adsorption of dyes, such as rhodamine B (RhB).

Polyethylene oxide (PEO) is widely considered to be a highly promising solid polymer electrolyte (SPE) owing to its flexibility, excellent mechanical and chemical stability, and safety. However, PEO still faces challenges in the application of all-solid-state lithium-sulfur batteries (ASSLSBs), such as low ion transport efficiency, lithium dendrite formation, and complex polysulfide shuttle effects. Herein, a unique ring-funnel β-cyclodextrin (β-CD) is introduced as a functional additive into the PEO matrix for structural reconfiguration as a composite solid electrolyte (CSE). The strong non-covalent interactions between β-CD and PEO reveals that the ordered arrangement of the PEO chains is disrupted because the dihedral and torsional angles are disturbed. These interactions significantly expand the amorphous regions of PEO, which increases the ion transport pathways and enhances the chain flexibility to improve ionic conductivity and electrochemical performance. Additionally, β-CD could strengthen the immobilization of TFSI⁻, further promoting Li⁺ dissociation and rapid migration, while effectively suppressing lithium dendrite growth and the polysulfide shuttle effect. As a result, the discharge capacity of ASSLSBs with PEO-LiTFSI-β-CD retain at 650.5 mAh·g⁻ 1 after 200 cycles, exhibiting a coulombic efficiency close to 98 %, which provide a novel design strategy for preparing high-performance and durable SPE for ASSLSBs.

Lactobacillus acidophilus GIM1.208 (LA) β-glucosidase (BGL) converts glycosides from Rosa roxburghii Tratt (RRT) to release more active aglycones. This study purified LA BGL and investigated it interaction with rosamultin in RRT. The isolated and purified BGL in the study had higher purity and activity, and the proportion of ordered structure in its secondary structure was greater than 60%, indicating better structural stability. The hydrolysis of purified BGL hydrolyzed rosamultin to tormentic acid at a rate of 25.2% (p<0.01), and the hypoglycemic activity of tormentic acid was higher than that of rosamultin. Rosamultin causes BGL to undergo massive aggregation and enhances the hydrogen bonding network structure. Thermodynamic analyses indicate that their binding is a non-spontaneous exothermic entropy-decreasing reaction, with the main forces being hydrogen bonding, van der Waals forces, or protonation forces. Additionally, their thermodynamic binding constant Kd=2.976×10 -5 mol/L and dissociation constant K D =2.67×10 -5 mol/L indicate that the two have high affinity and strong interaction. In conclusion, BGL has the ability to hydrolyze rosamultin to release tormentic acid and they have a strong interaction. The results of this study can provide a reference for the study of glycoside changes and their interactions in RRT fermented by LA.
