Bi2WO6:Ho3+, Yb3+/g-C3N4 (BHY/CN) photocatalysts are successfully loaded on polyacrylonitrile (PAN) nanofibers by electrospinning technology, which combines an upconversion effect and heterojunctions to achieve dual-functional characteristics. Polymer-modified photocatalytic materials offer a large specific surface area of 24.1 m(2)/g and a pore volume of 0.1 cm(3)/g, promoting the utility of solar energy. The introduction of rare earth ions and g-C3N4 optimizes the structural band gap, which broadens the light absorption range and promotes electron transfer. Moreover, the heterojunction between Bi2WO6 and g-C3N4 has suppressed the complexation of photoinduced carriers, further improving catalytic performance. The optimized photocatalysts have higher photocatalytic activity with degrading 92.6% tetracycline-hydrochloride (120 min) under simulated sunlight irradiation. The optical thermometry has also been achieved based on the fluorescence intensity ratio technique, where the maximum absolute and relative sensitivity values of BHY/CN-1:6@PAN are 3.322% K-1 and 0.842% K-1, respectively. This dual-functional nanofibers with excellent mechanical properties provide noncontact temperature feedback and efficient catalytic performance for better wastewater treatment and ecological restoration in extreme harsh environments.

Ethnopharmacological relevance: Danlong oral liquid (DLOL) is a traditional Chinese proprietary medicine commonly used to treat chronic respiratory diseases, including bronchial asthma and chronic obstructive pulmonary disease. However, the therapeutic effects and pharmacological mechanisms of DLOL in improving airway remodeling remain unclear. Aims of the study: This study utilizes in vivo and in vitro experiments, serum pharmacological analysis, and network-based pharmacology approaches to investigate the effects and mechanisms of DLOL on airway remodeling and epithelial-mesenchymal transition (EMT) in asthma. Methods: An asthma model was established through ovalbumins (OVA) sensitization and challenge in BALB/c mice to observe the effects of DLOL on airway hyperresponsiveness (AHR), inflammation, remodeling, and molecular markers of EMT. The absorbed chemical prototype constituents of DLOL were analyzed using Ultra Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS), and targets for asthma and airway remodeling were predicted using a network pharmacology approach. Key biological processes and signaling pathways were analyzed. Additionally, TGF-(31 was used to induce EMT in BEAS-2B cells. TGF-(31 and DLOLcontaining serum were screened to determine the optimal time and concentration in BEAS-2B cells using CCK8 assays. The cell scratch assay was used to assess cell migration, while immunofluorescence and immunohistochemistry were employed to evaluate protein expression levels. Results: DLOL improved AHR in asthmatic mice, reduced inflammatory cell infiltration in lung tissue, decreased airway wall and smooth muscle thickness, and reduced collagen deposition. It also down-regulated mesenchymal markers (N-cadherin, vimentin, a-SMA) and key remodeling factors (TGF-(31, MMP9), while up-regulating the epithelial marker E-cadherin. A total of 17 absorbed chemical prototype constituents were identified, predicting 54 core targets involved in airway remodeling. Fo

Natural polysaccharide bioplastics are a promising alternative for nondegradable food packaging;however, some properties cannot be fully matched by petrochemical plastics. Herein, a biodegradable, eco-friendly bioplastic is constructed through dynamic electrostatic induct intermolecular cross-linking. By entropy initiation and electrostatic self-assembly, the protonated chitosan (CC) can be tightly bound to the polyelectrolyte complex (QS) composed of the quaternary ammonium chitosan and sodium alginate, further inducing crystallization through hydrogen bonds, resulting in the tensile strength and toughness of natural polysaccharide bioplastic (QSCC(1/7(20))) being 5.4 and 13.4 times that of QS, respectively. Concurrently, the water resistance and gas barrier properties are also remarkably elevated. Due to the synergistic antibacterial activity of -NH3+ and -N+(CH3)(3) groups, the QSCC(1/7(20)) achieves 3 h rapid sterilization (>= 95%) and at least 5 day long-term bacteriostasis (>= 99%), leading to foldable QSCC(1/7(20)) that can effectively keep perishable fruit fresh for 8 and 7 days in static and dynamic situations, respectively. Furthermore, QSCC(1/7(20)) can be recycled by low-carbon and water-assistance sustainable processes. Therefore, this work offers a prospective way to substitute petrochemical plastic packaging.

Polymicrobial wound infection represents a significant contributor to infectious disease-related morbidity and mortality globally. Traditionally, the management of such infection relies heavily on high doses of antibiotics, often resulting in systemic side effects and exacerbating antibiotic resistance. Consequently, there is an urgent need to develop a safe and effective platform for antibiotic-free treatment of polymicrobial wound infections. In this study, a near-infrared (NIR) light-actuated nanofibrous membrane incorporating botanicals and nanozymes is presented for antibiotic-free triple-synergistic therapy against polymicrobial wound infections. The membrane integrates berberine hydrochloride (BBH)-loaded hollow zinc-doped carbon nanocubes into polyvinyl alcohol (PVA) nanofibrous membranes. Upon low-intensity 808 nm NIR laser irradiation (0.3 W cm-2), the membrane achieved a controlled release of BBH and enhanced peroxidase-like (POD-like) enzyme activity. This NIR light-actuated botanical/photothermal therapy (PTT)/chemodynamic therapy (CDT) system demonstrated high efficacy in eradicating methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa both in vitro and in vivo. Furthermore, it mitigated inflammation and promoted wound healing in polymicrobial infection wounds, highlighting its potential as a promising alternative to antibiotic-based therapies. In this work, BBH loaded hollow Zn doped carbon nanocubes are intergrated into PVA membrances to prepare a skin permissible NIR actuated botanicals/nanozymes nanofibers membrance for triple synergistic therapy against ploymicrobial wound infections. image

Plain Language SummaryChina has the largest number of people living with the hepatitis C virus. The prevalence of hepatitis C among people who inject drugs is high at 40-50%, significantly higher than the prevalence among other high-risk groups. Preventing the transmission of hepatitis C among people who inject drugs is essential to avoid future liver diseases. We used a mathematical model to evaluate the impacts of different intervention strategies on the incidence, prevalence and mortality of hepatitis C among people who inject drugs in China by 2030. We found that scaled-up hepatitis C screening and treatment integrated with harm reduction programs demonstrated the most substantial reduction in the burden of hepatitis C;specifically, the incidence of hepatitis C in 2030 is reduced by 81.42% and hepatitis-C-related deaths are reduced by 91.94%. Increasing harm reduction program coverage among people who inject drugs has a greater impact in terms of reducing the burden of hepatitis C virus compared with enhanced linkage to care or test frequency alone. Substantial improvements in both testing and treatment integrated with existing harm reduction programs are essential to achieve the goal of eliminating hepatitis C in China by 2030. IntroductionInjection drug use is the main transmission route of hepatitis C virus (HCV) in China. The prevalence of HCV remains high at 40-50% among people who inject drugs (PWID). We developed a mathematical model to predict the impacts of different HCV intervention strategies on the HCV burden in Chinese PWID by *** developed a dynamic deterministic mathematical model to simulate the transmission of HCV among PWID in China between 2016 and 2030, using domestic data based on the real cascade of HCV care.

Surface defect detection is a critical aspect of the manufacturing process, requiring accurate detection methods to ensure product quality. Traditional fully-supervised detection methods require extensive annotated data, leading to significant labeling costs. This study introduces a novel self-supervised surface defect detection method using synthetic pseudo defect samples, achieving pixel-level detection with only normal samples for training. Adopting a structure similar to DRAEM, this method concatenates the generative and discriminative networks, using both the input and output of the generative model to enhance the discriminative network's decision boundaries. Introducing a multi-head attention mechanism and a Group Aggregation Bridge (GAB) module for feature fusion significantly boosts the discriminative network's performance and segmentation accuracy. Extensive comparative experiments with a variety of similar anomaly detection algorithms have demonstrated the superior segmentation performance of this work.

Prussian blue analogues (PBAs) are considered as promising cathode materials for capacitive deionization (CDI) technology due to their 3D open-frame structure and tunable redox active sites. However, the inevitably high content of [Fe(CN)6] vacancies in the crystal structure results in a low salt adsorption capacity (SAC) and poor recycling performance. Herein, a high-salt nano-reaction system is established by mechanochemical ball milling, enabling the preparation of a variety of highly crystallized PBAs (metal hexacyanoferrate, MHCF-B-170, M = Ni, Co, or Cu) with low vacancies (0.05-0.06 per formula unit). The reduction of vacancies in the PBAs lattice not only strengthens the conductivity and promotes the rapid transfer of electrons, but also reduces the migration energy barrier and accelerates the fast and reversible diffusion of Na+ ions. The structural characterization method and theoretical simulation demonstrates the excellent reversibility and crystal structure stability of MHCF-B-170 during the CDI process. Impressively, the NiHCF-B-170 exhibits excellent CDI performance, characterized by an exceptionally high SAC of up to 101.4 mg g-1 at 1.2 V, and demonstrates remarkable cycle stability with no significant degradation observed even after 100 cycles. This PBAs with low Fe(CN)6 vacancies are expected to be a competitive candidate material for CDI electrodes.

Rehmannia glutinosa polysaccharide (RGP) has been reported to exhibit anti-anxiety effects, yet the underlying mechanism remains unclear. Chronic constant light (CCL) induced cognitive dysfunction associated with oxidative stress in mice has been reported. Here, the neuroprotective effect of RGP on hippocampal neuron damage in CCL-treated mice was investigated. In vivo study, mice were subjected to CCL for 4 weeks and/or oral administration of 100, 200 and 400 mg/kg RGP every other day. In vitro experiment, hippocampal neuron cells (HT-22) was exposed to LED light and/or supplemented with 62.5, 125 and 250 mu g/mL RGP. Mice exposed to CCL showed impaired cognitive and depressive-like behavior in the hippocampus, which were reversed by RGP. Meanwhile, RGP reversed light-induced oxidative stress and autophagy both in mice and hippocampal neuron cells (HT-22). Furthermore, compared with Light-exposed group, RGP treatment activated the AKT/mTOR pathway. Importantly, the AKT inhibitor Perifosine significantly weakened the neuroprotective of RGP on Lightinduced oxidative stress and autophagy in HT-22 cells by inhibiting AKT/mTOR pathway and increasing the content of autophagy-related protein. Our data demonstrated, for the first time, that oxidative stress and the AKT/mTOR pathway plays a critical role in Light-induced apoptosis and autophagic cell death in mice and HT-22 cells.

Infrared thermography technology is a noninvasiveness and real-time imaging method, it has attracted enormous attentions for blood flow imaging. However, the implementation of infrared thermography technology is still limited by the poor imaging quality caused by the low temperature discrimination between the target blood vessel and background. Herein, we reported a flexible and low-cost MXene based photothermal microheater for enhancing the infrared imaging of blood flow. In the experiment, MXene films with specific thickness was prepared by vacuum filtering different concentrations of MXene colloidal solutions. Thereafter, the microheaters were fabricated by assembling the MXene films on the PU tape/PDMS substrate, and then sealed with another layer of pure PDMS film on the top of MXene film. The photothermal performance of the microheaters were evaluated by using an 808-nm laser as the exciting source. Experimental results show that the optimal microheater（MXene content: 17.5 mg） can reach a safe temperature of 41.5°C with 43.9 s under the light irradiation of100 mW·cm-2. Moreover, it can be stabilized at the equilibrium temperate for over 25 min. Finally, the above optimal microheater was used to accurately heat the simulated blood vessel. It shows that temperature difference of 3.3°C can be induced between the heated blood vessel and environment. As a result, it significantly enhances the quality of the infrared imaging of the blood flow in the simulated vascular network.
