Nowadays, the limited catalytic efficiency, metal leaching, and stability decrease during catalyst reuse hinder the heterogeneous catalysis application in water treatment. Moreover, the heterogeneous catalysis mechanism regarding novel sodium periodate (NaIO 4 )-based advanced oxidation process (AOP) is ambiguous. Herein, MgMn 2 O 4 spinel was synthesized through the co-precipitation method to test the NaIO 4 -based AOP’s mechanism. The morphological and physicochemical properties of MgMn 2 O 4 were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). In this research, 0.1 g L −1 MgMn 2 O 4 activated 1 mM NaIO 4 to remove 10 μM bisphenol A (BPA) in 60 min without toxic iodine species generation and the acute toxicity decrease through radical (iodine active substances, IO 3 • ) and non-radical ( 1 O 2 , Manganese (IV)-oxo species) pathways by utilizing X-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance (EPR), radical quenching experiments, and methyl phenyl sulfoxide (PMSO)-based probing experiment. With tetrahedral Mg 2+ introduction and the Mn 2+ /Mn 3+ /Mn 4+ redox domination, the MgMn 2 O 4 shows high catalytic ability for NaIO 4 . To summarize, this research would extend the mechanism for the NaIO 4 -based advanced oxidation process.

Smad ubiquitylation regulatory factor-1 (Smurf1) is one of C2-WW-HECT domain E3 ubiquitin ligases , it can regulate BMP pathway by mediating ubiquitylation degradation of Smad1/Smad5. Many functions about Smurf1 also are still unknown, especially in retina . This research is about to explore the role of Smurf1 in retina degeneration . Tail vein injection of sodium iodate (NaIO 3 ) in C57BL/6J mice was the animal model of retina degeneration. In NaIO 3 model, Smurf1 had more expression than normal mice. Specific Smurf1 inhibitor, A01, was injected into vitreous cavity. Results showed that inhibiting Smurf1 could alleviate acute retina injury, such as keeping a better retina structure in living imaging and histologic sections, less cell death and inflammation activation. Tert-butyl hydroperoxide (TBH) was used to establish oxidative stress injury in human retinal pigments epithelial cell line (ARPE-19). Oxidative stress injury gradually caused co-upregulation of Smurf1, TGF-β1 and phosphorylated NF-κB (pNF-κB). TGF-β1 could directly induce Smurf1 expression. Inhibiting Smurf1 had an anti-epithelial mesenchymal transition (anti-EMT) function. Similarly, A01 also could inhibit the expression of pNF-κB, NLRP3 and IL-1β. At last, after searching bioinformatics database, Smurf1 had a possible interaction with beta-transducin repeat containing E3 ubiquitin protein ligase (β-TrCP), another E3 ubiquitin ligases. β-TrCP can mediate ubiquitination degradation of p-IκBα. Lentivirus- SMURF1 was used to overexpress Smurf1, and GS143 was used to inhibit β-TrCP. The results showed Smurf1 could directly induce NF-κB, pNF-κB, and NLRP3 expression, and keep a stable β-TrCP expression. However, inhibiting β-TrCP could cause more NF-κB activation and NLRP3 expression. Therefore, β-TrCP may play a negative role in NF-κB pathway activation. In summary, Smurf1 plays a role in exacerbating oxidative stress injury and inflammation in retina and may become a potential therapeutic target in ROS injury of retina.

In this article, a simple, effective chemiluminescence (CL) method for the detection of methylparaben (MP) in cosmetic samples was developed based on an IO 4 − –H 2 O 2 –carbon nitrogen quantum dots (CNQDs) system without a separation process. The results indicated that the redox reaction between periodate and hydrogen peroxide released hydroxide radicals and superoxide radical anions in the presence of bicarbonate. These two radicals were responsible for the formation of excited luminophor CNQD* with a maximum wavelength at 480 nm. Due to the competitive reaction with hydroxide radicals, CL intensity was markedly diminished in the presence of MP. The relative standard deviation in the intraday assay was below 5.5% ( n = 9), and the detection limit was as low as 0.50 μmol/L. The proposed method allowed for the successful, selective determination of MP in cosmetics.

Viscose fiber was oxidized with sodium periodate to prepare a reactive dialdehyde viscose fiber (DAVF) containing abundant aldehyde groups. A solid amine adsorbent (DAVF-PEI) with high amino density for CO 2 capture was then prepared by modifying DAVF with polyethylenimine (PEI). Response surface methodology (RSM) based on a three-level, three-factorial design was used to optimize the synthesis conditions of DAVF, in which multiple linear regression equations of aldehyde content and fiber mass loss degree were constructed. The well-designed DAVF was then employed as a support to graft with PEI via Schiff base reaction to prepare a solid amine fiber (DAVF-PEI) for CO 2 adsorption. The experimental results verified that DAVF-PEI possessed good thermo-stability and high CO 2 adsorption capacity (4.11 mmol/g). DAVF-PEI also showed promising regeneration performance, which could maintain almost the same adsorption capacity for CO 2 after ten adsorption and desorption recycles.

With the improvement of medical and health care level in our society, the demand for antibacterial materials is increasing. In this work, we prepared the antibacterial materials by loading silver nanoparticles (AgNPs) on the dialdehyde cellulose (DAC) with in-situ synthesis method. DAC was prepared by pretreating cellulose fiber with sodium metaperiodate (NaIO 4 ) to convert the hydroxyl group into aldehyde group, and then reacted with silver nitrate (AgNO 3 ) to obtain AgNPs loaded on DAC. UV–Vis results show that the characteristic absorption peak of AgNPs at 428 nm appeared in the AgNPs-loaded-DAC. It was observed by SEM that the spherical AgNPs were distributed uniformly on the DAC surface without obvious flocculation. The color of DAC was not changed significantly, indicating that a small amount of AgNPs was loaded. In addition, sodium citrate (Na 3 C 6 H 5 O 7 ) was added in the reaction of DAC and AgNO 3 and its effect on the formation of AgNPs was studied. The results demonstrated that the color of DAC turned deeper and finally dark yellow with reaction time extended. When the reaction time was 60 h, the spherical AgNPs were gradually grown and transformed into triangular prism on the DAC surface. The antibacterial properties of AgNPs showed inhibition zones of 4.90 mm and 7.35 mm (60 h) against Gram-negative ( E. coli ) and Gram-positive ( S. aureus ), respectively, which increased by 40.00% and 14.85% compared with spherical AgNPs (2.5 h) obtained without Na 3 C 6 H 5 O 7 . The research of AgNPs-loaded cellulose-based materials promotes the development prospect of new nano-antibacterial materials. Graphical abstract

Lycii Fructus (LF) is a medicinal-edible homology material frequently used for treating age-related macular degeneration (AMD) in Chinese medicine. Abundant of literatures verified the retina protection effect of LF on AMD-like animal models. However, previous studies on LF attenuating retinal damage mainly focused on its protection effect on pigment epithelial cells and optic ganglion cells while few reports on Müller cells. In the current study, we found that LF extracts attenuated oxidation damages and inhibited cell apoptosis of retina on a mouse retinal injury model induced by sodium iodate. LF extracts also increased expressions of Müller cell biomarker glutamine synthetase of eyeballs of model mice, which indicated that LF extract protected Müller cell from oxidation injury induced by sodium iodate. In Müller cell MIO-M1 cultures, LF also significantly inhibited cellular apoptosis induced by NaIO 3 by regulating Nrf2/HO-1 signaling pathway and the aqueous extracts exerted better active tendency than ethanol extracts. These data implied that the antioxidant effect of LF on protecting Müller cell might contribute to its retina repair function, thereby providing more scientific evidences for the development of LF as an alternative therapy or preventive measures for AMD.

Retinal pigment epithelium (RPE) cell damage is implicated in the pathogenesis of age-related macular degeneration (AMD). An increase of interferon-γ (IFN-γ) levels was observed in patients with AMD, but whether inflammatory factors are causally related to AMD progression is unclear. Here, we demonstrate a direct causal relationship between IFN-γ and RPE cell death. IFN-γ induced human retinal pigment epithelial cell (ARPE-19) death accompanied by increases in Fe 2+ , reactive oxygen species, lipid peroxidation, and glutathione (GSH) depletion, which are main characteristics of ferroptosis. Mechanistically, IFN-γ upregulates the level of intracellular Fe 2+ through inhibiting Fe 2+ efflux protein SLC40A1 and induces GSH depletion by blocking cystine/glutamate antiporter, System xc-. At the same time, treatment with IFN-γ decreases the level of glutathione peroxidase 4 (GPx4), rendering the cells more sensitive to ferroptosis. JAK1/2 and STAT1 inhibitors could reverse the reduction of SLC7A11, GPx4 and GSH expression induced by IFN-γ, indicating IFN-γ induces ARPE-19 cell ferroptosis via activation of the JAK1-2/STAT1/SLC7A11 signaling pathway. The above results were largely confirmed in IFN-γ-treated mice in vivo . Finally, we used sodium iodate (NaIO 3 )-induced retinal degeneration to further explore the role of ferroptosis in AMD in vivo . Consistent with the role of IFN-γ, treatment with NaIO 3 decreased SLC7A11, GPx4 and SLC40A1 expressions. NaIO 3 -induced RPE damage was accompanied by increased iron, lipid peroxidation products (4-hydroxynonenal, malondialdehyde), and GSH depletion, and ferroptosis inhibitors could reverse the above phenomenon. Taken together, our findings suggest that inhibiting ferroptosis or reducing IFN-γ may serve as a promising target for AMD.

Membrane separation technology is an important method of treating oily wastewater with great potential for development. However, preparation of membranes for efficiently separating complex oil-water mixtures continues to be challenging. In this study, a strategy for efficient construction of asymmetric wetting surfaces was designed, and successfully prepared an asymmetric super wetting Janus polyvinylidene fluoride (PVDF) modified separation membrane to separate complex oil-water emulsion. The composite PVDF membrane was prepared using a non-woven fabric substrate and phase conversion method. Subsequently, composite membrane was rapidly hydrophilic modified on one side using tannic acid and 3-aminopropyltriethoxysilane under the strong oxidizing effect of oxidant sodium periodate. Then non-woven fabric substrate was peeled off to obtain a Janus PVDF modified separation membrane. The front and back sides of the separation membrane have highly asymmetric micromorphology and wettability. The front side has hydrophilic/underwater oleophobic wettability (with a water contact angle of 31°). The separation efficiency of oil-in-water emulsion is up to 99.5%, while the back side has super lipophilic/underoil hydrophobic wettability (with a water contact angle of 131°). The separation efficiency of water-in-oil emulsion is up to 98.6%, improving the efficiency of oil in water separation and application range.

Soybean meal, a by-product of soybean oil production, exhibits poor water resistance and is highly susceptible to mold, which are significant limitations hindering its large-scale industrial application. Inspired by the phenolic-amine chemistry, a fully bio-based soy protein wood adhesive was engineered to achieve excellent water resistance and environmental benefits. The process starts with oxidation of alkaline lignin using sodium periodate (NaIO 4 ) to generate aldehyde/quinone functionality on the expense of some aliphatic/phenolic hydroxyl groups, for promoting its subsequent interaction with soy protein to yield target adhesive by Schiff-base formation and Michael addition reaction. Importantly, residual NaIO 4 was meticulously removed to minimize its impact on the bonded substrate, the cross-linked network, and the environment, as it does not participate in the construction of the cross-linked architecture. The results showed that the dry and wet shear strength of SM-OL1.5 increased by 51.2 % and 80.8 % to 1.83 MPa and 0.94 MPa compared with SM adhesives, surpassing the China National Standard (GB/T 9846–2015, ≥0.7 MPa). Interestingly, the developed adhesive formulation exhibited mildew resistance, which can be attributed to the inherent feature of lignin to disrupt cell membranes and alter permeability, leading to cell lysis. Furthermore, the hybridized adhesive showcased minimal environmental impact, low volatile organic compound (VOC) emissions, and full compliance with global sustainability initiatives, making it a promising candidate for eco-friendly wood adhesive applications.

Oil/water mixtures from industrial and domestic wastewater adversely affect the environment and human beings. In this context, the development of a facile and improved separation method is crucial. Herein, dopamine was used as a bioadhesive to bind tea polyphenol (TP) onto the surface of a polyvinylidene fluoride (PVDF) membrane to form the first hydrophilic polymer network. Sodium periodate (NaIO4) is considered an oxidising agent for triggering self-polymerisation and can be used to introduce hydrophilic groups via surface manipulation to form the second hydrophilic network. In contrast to the individual polydopamine (PDA) and TP/NaIO4composite coatings for a hydrophobic PVDF microfiltration membrane, a combination of PDA, TP, and NaIO4has achieved the most facile treatment process for transforming the hydrophobic membrane into the hydrophilic state. The hierarchical superhydrophilic network structure with a simultaneous underwater superoleophobic membrane exhibited excellent performance in separating various oil-in-water emulsions, with a high water flux (1530 L.m−2h−1.bar) and improved rejection (98%). The water contact angle of the modified membrane was 0° in 1 s. Moreover, the steady polyphenol coating was applied onto the surface, which endowed the membrane with an adequate antifouling and recovery capability and a robust durability against immersion in an acid, alkali, or salt solution. This facile scale-up method depends on in situ plant-inspired chemistry and has remarkable potential for practical applications.Keywords:superior separation method;hierarchical superhydrophilic network;steady polyphenol coating;oil-in-water emulsion

Age-related macular degeneration (AMD) is a prominent cause of vision loss among the elderly, and the treatment options for dry AMD (dAMD) are severely limited. Lutein has a favorable effect on the treatment of dAMD. Algae oil, rich in docosahexaenoic acid (DHA), is considered an effective intervention for eye diseases. In this study, casein-mannose conjugates were prepared to form algal oil-in-water Pickering emulsions by ultrasound-assisted Maillard reaction. As the ultrasound time increased from 0 to 25 min, the droplet size decreased to 648.2 ± 21.18 nm, which substantially improved the stability of the Pickering emulsions. The retention of lutein in the Pickering emulsions under ultrasonic treatment for 20 min was significantly improved under different conditions. The simulated gastrointestinal digestion revealed that ultrasound-assisted Pickering emulsions are an effective method for improving the bioaccessibility of lutein (19.76%–53.34%). In vivo studies elucidated that the lutein-loaded Pickering emulsions could effectively alleviate retinal thinning induced by sodium iodate (NaIO3) in mice with dAMD. Mechanistically, lutein-loaded Pickering emulsions significantly reduced oxidative stress by decreasing the MDA level, increasing the SOD production, and reducing the retinal ROS production. These findings explored the protective effects of lutein-loaded Pickering emulsions on dAMD and offered promising prospects for the nutritional intervention of dAMD.

A green and facile method was proposed to prepare robust and fully bio-based modified paper in this study, which involved in layer-by-layer deposition of chitosan (CS) and mussel adhesive protein-mimetic polymer (dopamine-grafted carboxymethyl cellulose, CMC- g -DA) on paper surface and subsequent oxidative cross-linking by sodium periodate . The mechanical, barrier and antibacterial properties of the cross-linked multilayer-modified paper significantly improved with the increased bilayer numbers. Compared with unmodified paper, cross-linked (CS/CMC- g -DA) 6 multilayer-modified paper exhibited 71.6 % improvement in tensile strength , 69.2 % and 56.3 % decline in air and water vapor permeability, as well as above 90 % antibacterial efficiency against S. aureus and E. coli . Particularly, the cross-linked multilayer-modified paper maintained outstanding functional stability even after suffering from vigorously corrosive treatment. The obtained functional paper effectively extended the shelf-life of Agaricus bisporus to 6 days under ambient conditions. We believed that the prepared robust functional paper in this study will have promising application prospect in food packaging field.
