Macrophage polarization serves an important role in immune regulation that is regulated by T‑cell immunoglobulin‑mucin‑3 (Tim‑3). The objective of the present study was to explore the role of 1,25‑dihydroxy‑vitamin D3 [1,25(OH)2D3] in macrophage polarization. Plasmid transfection techniques were applied to prepare RAW264.7 cells with silenced or overexpressed Tim‑3 gene. ELISAs were used to examine the level of inflammatory factors secreted by macrophages. Proteins levels were determined by western blot analysis. mRNAs expression levels were assessed using reverse transcription quantitative polymerase chain reaction. It was identified that 1,25(OH)2D3 upregulated Tim‑3 levels and promoted the secretion of interleukin (IL)‑10. 1,25(OH)2D3 was also observed to increase the level of transforming growth factor‑β and to inhibit tumor necrosis factor‑α and IL‑6. The results also suggested that Tim‑3 gene silencing induced macrophages polarization to classically activated macrophages (M1), and that overexpression of the Tim‑3 gene induced macrophage polarization to alternatively activated macrophages (M2). 1,25(OH)2D3 treatment upregulated the expression level of Tim‑3 in macrophages, which promoted cell polarization to M2 and inhibited polarization to M1. The data from the present study indicated that Tim‑3 may induce macrophage polarization to M2, and that 1,25(OH)2D3 produced immunosuppressive effects by upregulating Tim‑3.

Food safety is essential for protecting public health. This study introduces a novel microneedle (MN) patch that employs a pH-responsive colorimetric mechanism for the real-time, easy, and visible detection of meat freshness. The patch is a pH-responsive colorimetric microneedle (C3G/HAMA@MN) patch composed of eco-friendly bio-based components, specifically methacryloylated hyaluronic acid (HAMA) and cyanidin-3-O-glucoside (C3G). Its mechanical strength reaches 7 N per needle, capable of penetrating over 85% of meat tissue. The distinctive structural design allows the microneedle tip to quickly and directly penetrate the meat tissue, extracting interstitial fluid in situ and promptly transferring it to the backing layer. The backing layer visually indicates pH changes in real time. The color change from light to dark matches freshness levels at different deterioration stages. Without sophisticated instruments, consumers may notice the patch's color change in two minutes using their vision, allowing for simple and reliable food quality inspection. A powerful new instrument for on-site food safety monitoring combines real-time display, easy interpretation, and biodegradable materials.

The anti‑inflammatory effects of aloin, a bioactive ingredient extracted from Aloe vera, have been described previously. The present study aimed to assess these effects and explore the underlying molecular mechanisms. RAW264.7 cells were incubated with different doses of aloin (100, 150 and 200 µg/ml) and lipopolysaccharide (LPS; 100 ng/ml) for the indicated times. Then, inducible nitric oxide synthase (iNOS) and cyclooxygenase‑2 expression levels were detected by western blot analysis and reverse transcription polymerase chain reaction (RT‑PCR).The concentrations of inflammatory cytokines in the cell culture supernatant were determined by ELISA. Total nitric oxide (NO) assay and reactive oxygen species (ROS) kits were used to detect NO and ROS levels, respectively. Mitogen‑activated protein kinase, nuclear factor κB and Janus kinase‑signal transducer and activator of transcription (JAK‑STAT) pathway activation were verified by western blot analysis. Confocal and nucleocytoplasmic separation experiments were used to detect STAT nuclear translocation. It was identified that aloin decreased the level of LPS‑induced iNOS expression, inhibiting the release of interleukin (IL)‑1β, IL‑6, tumour necrosis factor‑α and NO dose‑dependently. Mechanistically, aloin suppressed LPS‑induced JAK1‑STAT1/3 activation and STAT1/3 nuclear translocation. Additionally, LPS‑induced ROS production was inhibited by aloin. Collectively, these data suggest that aloin attenuated LPS‑induced inflammation by inhibiting ROS‑mediated activation of the JAK1‑STAT1/3 signalling pathway, thereby inhibiting the nuclear translocation of STAT1/3 in RAW264.7 cells. The present study provides an experimental basis for the clinical application of aloin in inflammatory‑associated diseases.

An electrochemical immunosensor was fabricated to identify CA15-3, a biomarker for breast cancer (BC). A composite sensor substrate made of “zeolitic imidazolate framework-8” (ZIF-8) and “reduced graphene oxide” (rGO) was chosen and its conductivity was further improved by the addition of chitosan (CS)-doped gold nanoparticles (AuNPs). The CS@AuNPs are able to conjugate with antibodies via the strong Au-S interaction, which offers multiple active sites for antibody immobilization and enhances the sensor performance. This immunosensor is capable of ultrasensitive detection of CA15-3 by specific antigen–antibody –interactions. In healthy people, normal serum CA15-3 is up to 25 U/mL. Under optimized experimental conditions, the alteration in the signal intensity measured by the sensor was related to the CA15-3 activity. The quantitative relationship was linear over 0.001–400 U/mL with a limit of detection (LOD) of 0.0031 U/mL at a “signal-to-noise ratio” (S/N) of 3 and a “correlation coefficient” (r2) of 0.9983. The developed immunosensor showed great accuracy, stability, and selectivity, and was able to detect CA15-3 in human serum samples. These results validate its potential as a reliable analytical platform for BC diagnosis and early clinical screening.

3-Acetamido-5-acetylfuran(3A5AF) is a nitrogen-containing fine chemical and has broad application prospects and high research value. Herein, we report a mild and efficient method for the synthesis of 3A5AF from N-acetyl- d -glucosamine (NAG). The influence of solvent, temperature and additive on the catalytic performance was also studied. The Lewis acids with high catalytic efficiency have been smoothly screened. The highest yield (41.57%) of 3A5AF was obtained in the presence of B 2 O 3 and MgCl 2 ·6H 2 O at 180 °C for 60 min under normal atmospheric conditions. The reaction pathway was explored by LC-MS, 1 H NMR, 13 C NMR and FT-IR spectra. Compared with the microwave method and hydrothermal method , the optimized reaction condition was relatively mild. Moreover, the catalyst MgCl 2 ·6H 2 O is low-cost and environmentally friendly.

Novel Sr 3 Y(PO 4 ) 3 :Dy 3+ , Eu 3+ (SYP:Dy 3+ , Eu 3+ ) phosphors were synthesized by a standard solid-state reaction under an ambient air atmosphere and their structural and optical properties were investigated. XRD and diffuse reflectance spectra (DRS) were used to explore structural properties. The former showed that single phase phosphors were obtained and that the rare earth ions entered into the cubic host by substituting the smaller Y 3+ ions and thereby enlarging the unit cell. The DRS indicated that the host has a direct bandgap of 4.5 eV. Under 393 nm excitation, a strong and stable warm white light emission with high color purity was achieved in SY 0.92 P:0.06Dy 3+ , 0.04Eu 3+ . The energy transfer from Dy 3+ to Eu 3+ ions was investigated and the related mechanism was discussed based on the optical spectra and emission decay curves. The thermal quenching of emission is similar to that of YAG:0.06Ce 3+ . The results show the single phase phosphor is potential in warm white LED.

NASICON-type Na 4 MnCr(PO 4 ) 3 (NMCP) has gained significant attention due to its prominent capacity and voltage platform. However, poor intrinsic electron conductivity severely obstructed its wider application. Here, the NMCP was decorated through structurally integrated with the high conductive carbon nanotubes (CNTs) component via the sol-gel method. The CNTs additive was tightly implanted NMCP bulk, providing fast electron transfer rates, further reduced charge transfer resistance and ohmic resistance , and improving the electrochemical properties of NMCP during the reversible intercalation/deintercalation of Na + . Finally, the as-prepared rambutan-like NMCP/C@CNTs could release a high reversible capability of 118.7 mAh g −1 at 0.1C and exhibit long durability over 500 cycles at a high rate of 10C. The pseudocapacitance contributions were investigated, and the Na storage mechanism was also demonstrated through in-situ synchrotron X-ray diffraction. The assembled NMCP/C@CNTs//HC full cell could deliver a high energy density of 364.4 Wh kg −1 . The encouraging electrochemical performance of the full cell will promote the development of sodium ion secondary batteries for large-scale applications in the future.

Lithium ion (Li + ) battery with conventional liquid electrolyte has typical and notorious security risk. Composite solid electrolyte integrating the merits of various electrolyte systems is an attractive alternative of liquid electrolyte for new-type safety and long-life lithium (Li) batteries. Herein, a 3D framework composite solid electrolyte based on Al 2 O 3 -modified Li 1.4 Al 0.4 Ti 1.6 (PO 4 ) 3 (Al 2 O 3 @LATP) was prepared by solution casting and scraping method. The 3D framework composite electrolyte exhibits admirable ionic conductivity (1.1 × 10 −4 S cm −1 at 60 °C), wide voltage window (4.8 V vs. Li/Li + ), good thermal stability, and satisfactory electrolyte/electrode interfacial compatibility. The Al 2 O 3 @LATP can not only impede Li dendrite growth, but also avoid the LATP reaction with Li anode. The assembled solid-state LiFePO 4 |Li battery with 3D framework composite solid electrolyte delivers a satisfactory capacity retention up to 95.2% after 400 cycles at 0.5 C and under 60 °C. The 3D framework structural design of solid electrolyte affords a promising option for realizing safe energy storage systems.

The all-inorganic perovskite CsPbI 3 quantum dots are difficult to achieve pure red stable luminescence due to their poor lattice thermodynamic stability and non-radiative recombination loss caused by surface halide vacancies. Therefore, the pure red perovskites are usually achieved by mixing the composition of halides (Br and I). In this work, CsPb(Br/I) 3 quantum dots (QDs) were synthesized by the hot-injection method under the synergistic effect of homophthalic acid (HA), 2-bromoethanesulphonic acid sodium salt (SBES), and oleylamine (OAm). By adjusting the molar ratio of passivates, the synergistic effect of multiple ligands can not only passivate the unliganded Pb 2+ -related defects on the surface of NCs, but also increase the formation energy of halide vacancies. Meanwhile, due to the bidentate structure of HA, smaller size of perovskites nanocrystals were obtained. Eventually, synergistic boost in device performance is achieved for color-by-blue white light-emitting diodes (WLEDs) with CIE coordinates of (0.3319, 0.3297) and have an external quantum efficiency (EQE) of 10.13%. This strategy paves an efficient way for improving the efficiency and stability of CsPb(Br/I) 3 NCs.

Organic–inorganic hybrid metal halide perovskites have played an important role in optoelectronic and photonic community owing to their remarkably high photoluminescence quantum yields and color tunability with ultrafast emission performance. Herein, two kinds of novel perovskite single crystals, i.e., TpyInCl 3 and TpyInCl 5 , grown by means of a solution-processed hydrothermal method are innovatively designed. Regulating the polarity of the precursor solution allows to fine-tune the light emission from pink to blue with an extremely short photoluminescence lifetime of 2.5 ns. The density functional theory calculations reveal that the unique luminescence characteristics are associated with the contribution of the terpyridine π–π* transition and the exciton quenching in the inorganic framework, that is, InCl 3 /[In 2 Cl 10 ] 4− , wherein the reduction of the recombination path and the increase of exciton quenching can effectively increase the luminous intensity. The current study provides a new paradigm toward designing multifunctional perovskite materials with tunable structure and electron dimension in emitter devices.

Metal-halide perovskite nanocrystals (NCs) are considered to be promising types of optoelectronic and photonic materials. The emission colors of the cesium lead halide perovskite (CsPbX3, X = Cl, Br, I) NCs depend on the joint influence of the emission peaks of the host and its dopant ions. Herein, we report a phosphine-free strategy to synthesize Mn-doped CsPb(Cl/Br)3 NCs to tune their optical properties in a wide color gamut. Colloidal Mn-doped CsPb(Cl/Br)3 NCs were synthesized by injecting Cs-oleate solution into the MnCl2 and PbBr2 precursor solution. The as-prepared Mn-doped CsPb(Cl/Br)3 NCs are highly crystalline and uniform sized nanocubes with two emission peaks, including the host emission around 450 nm and the Mn2+ dopant emission around 600 nm, which are sensitive to the MnCl2-to-PbBr2 molar feed ratio and the reaction temperature. By varying the MnCl2-to-PbBr2 molar feed ratio or the reaction temperature, the relative PL intensities of dual color emission can be manipulated, showing their ability in tunable color output.

Manganese-based NASICON-type compounds are promising as high-energy-density cathodes for sodium-ion batteries. However, the structural defects of Mn ions inside the crystal framework reduce the sodium storage capacity, voltage plateau, and cyclic stability of the cathodes. Here, a strategy to inhibit the Mn ion defects of Na4MnCr(PO4)3 has been proposed by using different phosphate sources. It is found that Na4MnCr(PO4)3 prepared with NH4H2PO4 (NMCP-N) exhibits less noticeable voltage hysteresis than that of Na4MnCr(PO4)3 prepared with H3PO4 (NMCP-H), indicating that the site occupation defects of Mn ions in the Na4MnCr(PO4)3 crystal structure are successfully suppressed, as confirmed by theoretical calculations and structural refinements. In the case of NMCP-N, a capacity of 109.7 mAh g–1 is delivered at 0.01 A g–1, and 54.2% capacity retention can be kept after 500 cycles at 0.5 A g–1, which is much better than that of the counterpart of NMCP-H (a lower capacity of 96.1 mAh g–1 and poorer cyclability of only 22.8% capacity retention after 500 cycles), showing that the structure defects strongly affect the sodium storage properties of Na4MnCr(PO4)3 cathodes. This work provides an effective strategy to manipulate the structure defects of Mn-based NASICON-type cathode materials to enhance their electrochemistry.
