Diabetic foot ulcers are severe diabetic complications, and promoting impaired angiogenesis is essential for wound healing. Pro-angiogenic galectin-3 is elevated in diabetic serum and promotes systemic insulin resistance that may impair wound healing. However, the exact role of galectin-3 in the regulation of diabetic wound healing remains unclear. Here, we demonstrate that galectin-3 promotes skin wound healing and angiogenesis via binding to its receptor integrin α5β1, and enhances downstream focal adhesion kinase phosphorylation by forming a liquid-liquid phase separation with integrin α5β1. Under diabetic conditions, aberrant accumulated advanced glycation end-products bind to galectin-3, blocking its interaction with integrin α5β1 and impairing angiogenesis. Topical treatment of recombinant galectin-3 in hydrogels promotes diabetic wound healing in rodents without causing systemic insulin resistance and synergizes with insulin. This study clarifies the binding of galectin-3 to integrin α5β1, instead of advanced glycation end-products, forming phase separation to promote angiogenesis and diabetic wound healing, laying the foundation for local galectin-3 therapy to treat diabetic foot ulcers.

The integration of nanobody and nanozyme has emerged as a transformative strategy in immunoassays, offering enhanced sensitivity, stability, and versatility compared to conventional antibody-enzyme conjugates. Herein, we successfully developed a ternary nanostructure by integrating silica nanoparticles (SNPs), polydopamine (PDA), and platinum nanoparticles (Pt NPs), yielding SNPs@PDA@Pt (SPP) with robust nanozyme catalytic activity. Notably, the SPP was surface-modified with polyethyleneimine (PEI) to generate positively charged PEI-modified SNPs@PDA@Pt (PSPP). This modification substantially improved the coupling efficiency with anti-3-phenoxybenzoic acid nanobodies (3-PBA Nbs) via electrostatic interactions. The PSPP-based coupling achieved a remarkable efficiency of 92.28 %, representing about a 4.5-fold increase over the SPP method (20.55 %). The PSPP@3-PBA Nbs nanocomposite was successfully integrated into both ELISA and LFIA platforms, achieving remarkable detection limits (0.001 ng/mL for ELISA and 0.003 ng/mL for LFIA). The nanocomposite also showed excellent stability, with no significant loss of immunobinding capacity or catalytic activity over 30 days. This work presents a novel design strategy for constructing high-performance nanozyme-nanobody nanocomposites, which shows great promise for ultra-sensitive 3-PBA detection in resource-limited settings.

In recent years, cellulose nanocrystals (CNCs) have been used to deliver drugs, showing great potential in exploring new methods for cancer chemotherapy. Nevertheless, insolubility, low stability, and bioavailability of the potential bioactive compounds obstruct the development of bioactive formulations. Here, we constructed a pH-responsive nanocarrier that can actively target hepatocellular carcinoma cells (HCC) to deliver insoluble drug curcumin (Cur). Firstly, the polyethyleneimine (PEI) was coated onto the surface of CNCs (CNCs@PEI), and then the 3-carboxyphenylboronic acid (BA) was grafted with the coated PEI (CNCs@PEI-BA). After that, Cur formed a borate structure with BA to load Cur (CNCs@PEI-BA-Cur) showed a high drug loading capacity of 15.74%. CNCs@PEI-BA-Cur actively target HCC, enter into lysosomes, and release Cur in response to the low pH value environment. Importantly, CNCs@PEI-BA-Cur released 10.7-folds of Cur in acidic environments (pH = 5.4) more than in neutral environments (pH = 7.2). Furthermore, the nanocarrier showed efficient active targeting of HCC and increased intracellular Cur concentrations, which allowed for the effective killing of HCC in 2D cell and 3D hepatoma cell microsphere models in vitro. In conclusion, this targeted and pH-responsive nanocarrier was expected to enhance the therapeutic of insoluble drugs for HCC.

With the development of the consumer society, low cost and high performance supercapacitors are being pursued. To realize the practical supercapacitors, developing the cheap and highly capacitive electrode is the most essential. However, it is a harsh challenge to achieve this target based on single-component electrode. Herein, a series of inexpensive ternary-metal-sulfides, 2MnS/Cu 2 S/ x ZnS/C ( x = 0, 0.5, 1, 2, 3) are synthesized by hydrothermal reaction and the subsequent calcination with expired manganese/copper gluconates as the raw materials for the electrode in the pseudocapacitors. Furthermore, the effect of ZnS's content on the electrochemical properties of the ternary composites is also investigated. Specially, the optimal 2MnS/Cu 2 S/xZnS/C( x = 1) can output a specific capacitance of 1608 F/g at 1 A/g in the three-electrode system, while the 2MnS/Cu 2 S/xZnS/C||AC( x = 1) asymmetric supercapacitor can deliver a specific capacitance of 194 F/g at 1 A/g with the desirable energy density (800 W/kg) and power density (70.9 Wh/kg), higher than those of other samples. Especially, even after 2000 cycles at 5.0 A/g, the 2MnS/Cu 2 S/xZnS/C||AC( x = 1) asymmetric supercapacitor also delivers the reversible specific capacitance of 103 F/g with high capacitance retention of 97.0 %, indicating high cycling stability. The outstanding performances of the optimal 2MnS/Cu 2 S/xZnS/C( x = 1) may be attributed to the bridge-effect of ZnS component, which makes up for the low conductivity of MnS component and the low capacitance of Cu 2 S component, thus achieving the best synergistic effect of ternary metal sulfide 2MnS/Cu 2 S/xZnS/C( x = 1) .

Objectives:We aimed to explore the potential role of omega-3 (ω-3) fatty acids on acne vulgaris by modulating gut microbiota.Materials and Methods:We randomly divided the untreated acne patients into two groups with or without ω-3 fatty acids intervention for 12 weeks. The Sprague Dawley (SD) rats with acne model were given isotretinoin, ω-3 fatty acids or their combination respectively. Then the colonic contents samples of the drug intervention SD rats were transferred to the pseudo sterile rats with acne model. The severity of the disease was assessed by the Global Acne Grading System (GAGS) score of the patients, and the swelling rate of auricle and the pathological section of the rat with acne model. The 16S rDNA gene sequencing was performed to detect the alteration of the gut microbiota.Results:ω-3 fatty acids could increase the diversity of the gut microbiota and regulate the flora structure positively both in the patients and rats, increase the abundance of butyric acid producing bacteria and GAGS score in the patients, and alleviate the inflammation and comedones of rats.Conclusion:Supplementation of ω-3 fatty acids could alleviate the inflammation of acne vulgaris by increasing the abundance of butyric acid producing bacteria.

The RAS-RAF-MEK-ERK signaling cascade is abnormally activated in various tumors, playing a crucial role in mediating tumor progression. As the key component at the terminal stage of this cascade, ERK1/2 emerges as a potential antitumor target and offers a promising therapeutic strategy for tumors harboring BRAF or RAS mutations. Here, we identified 36c with a (thiophen-3-yl)aminopyrimidine scaffold as a potent ERK1/2 inhibitor through structure-guided optimization for hit 18. In preclinical studies, 36c showed powerful ERK1/2 inhibitory activities (ERK1/2 IC50 = 0.11/0.08 nM) and potent antitumor efficacy both in vitro and in vivo against triple-negative breast cancer and colorectal cancer models harboring BRAF and RAS mutations. 36c could directly inhibit ERK1/2, significantly block the phosphorylation expression of their downstream substrates p90RSK and c-Myc, and induce cell apoptosis and incomplete autophagy-related cell death. Taken together, this work provides a promising ERK1/2 lead compound for multiple tumor-treatment drug discovery.

Yb3+/Er3+-doped Bi2(MoO4)3−z(WO4)z phosphors were synthesized via a hydrothermal method combined with subsequent calcination. Under the excitation of a light source of 980 nm, Bi2(MoO4)3:Yb3+/Er3+ phosphors exhibited strong upconversion green light and weak red light emissions. By doping WO42− in Bi2(MoO4)3:Yb3+/Er3+ phosphors, the upconversion luminescence intensity of the phosphors significantly enhanced, which is 42 times higher than that of the undoped WO42− phosphor. With an increase in WO42− doping content, the final color coordinates of Bi2(MoO4)3−z(WO4)z:Yb3+/Er3+ phosphors were (0.2352, 0.7274), which is closer to the standard green CIE coordinates. The maximum CP of WO42−-doped phosphors is as high as 116.68%, which is 74.44% higher than that of the undoped WO42− phosphor. Based on the thermally coupled energy levels (TCLs) of Er3+ (2H11/2/4S3/2 → 4I15/2) in Bi2(MoO4)2.7(WO4)0.3:14%Yb3+,3%Er3+ phosphor, the SR value reached a maximum of 0.0081 K−1 at 323 K and the SA value reached a maximum of 0.0099 K−1 at 398 K. The obtained Bi2(MoO4)3−z(WO4)z:Yb3+/Er3+ phosphors are suitable for upconversion luminescent materials for green displays and have potential advantages in optical temperature measurement.

Regulating the crystallization dynamics of perovskite films is key to improving the efficiency and operational stability of (FA0.83MA0.17Cs0.05)Pb(I0.85Br0.15)3perovskite solar cells (PSCs). However, precise regulation of the crystallization process remains challenging. Here, we introduce a reactive anti-solvent strategy based on the Kornblum reaction to modulate crystallization via in-situ chemical transformation. Specifically, trans-cinnamoyl chloride (TCC) is employed as a single-component anti-solvent additive that reacts with dimethyl sulfoxide (DMSO) in the perovskite precursor solution. The resulting acylation reaction generates carbonyl-containing products and sulfur ions. The carbonyl oxygen coordinates with Pb2+ions to form Pb–O bonds, which retard rapid crystallization, suppress heterogeneous nucleation, and facilitate the growth of larger perovskite grains with improved film uniformity. Additionally, the exothermic nature of the reaction accelerates local supersaturation and nucleation. This synergistic crystallization control significantly enhances the film morphology and device performance, yielding a champion power conversion efficiency (PCE) of 23.02% and a markedly improved fill factor (FF). This work provides a new pathway for anti-solvent engineering through in-situ chemical regulation, enabling efficient and scalable fabrication of high-performance PSCs.

In this study, the 500 keV He–ion irradiation effects were systematically analyzed in Sr 0.5 Zr 2 (PO 4 ) 3 –Ce 0.5 Sm 0.5 PO 4 composite ceramics used for nuclear waste form. The phase evolution was investigated at various ion doses of 1 × 10 16 , 1 × 10 17 , and 5 × 10 17 ions/cm² using GIXRD, Raman. Meanwhile, the irradiation effects at various depths of 100 nm, 1500 nm and 3000 nm in the typical sample with an ions dose of 5 × 10 17 ions/cm 2 were further observed through FIB–TEM and SEM. The results indicated that Sr 0.5 Zr 2 (PO 4 ) 3 phase transitioned from crystalline to amorphous state, while Ce 0.5 Sm 0.5 PO 4 phase exhibited crystalline–disorder transition. Furthermore, the microscopic strain changes of both post–irradiated phases were assessed by a geometric phase analysis (GPA) method, which revealed that Sr 0.5 Zr 2 (PO 4 ) 3 phase accumulated more lattice stress than Ce 0.5 Sm 0.5 PO 4 phase. Ultimately, this study confirmed that the irradiation resistance of Sr 0.5 Zr 2 (PO 4 ) 3 phase under He–ion irradiation was inferior to that of Ce 0.5 Sm 0.5 PO 4 phase.

A ratiometric luminescent probe was fabricated using adenosine monophosphate (AMP) as a bridging ligand and 3-carboxyphenylboronic acid (3-CPBA) as the sensitizer and functional ligand that allowed the probe to recognize hydrogen peroxide (H 2 O 2 ). The probe was labeled AMP-Tb/3-CPBA. Adding H 2 O 2 caused the nonluminescent 3-CPBA to be converted into 3-hydroxybenzoic acid, which strongly luminesces at 401 nm. This meant that adding H 2 O 2 decreased the AMP-Tb/3-CPBA luminescence intensity at 544 nm and caused luminescence at 401 nm. The 401 and 544 nm luminescence intensity ratio ( I 401 / I 544 ) was strongly associated with the H 2 O 2 concentration between 0.1 and 60.0 μM, and the detection limit was 0.23 μM. Dual emission reverse-change ratio luminescence sensing using the probe allowed environmental effects to be excluded and the assay to be very selective. We believe that the results pave the way for the development of new functionalized lanthanide coordination polymers for use in luminescence assays.

This study explored the relationship between the interfacial behavior of lactoferrin-(−)-epigallocatechin-3-gallate covalent complex (LF-EGCG) and the stability of high internal phase Pickering emulsions (HIPPEs). The formation of covalent bond between lactoferrin and polyphenol was verified by the increase in molecular weight. In LF-EGCG group, the surface hydrophobicity, interfacial pressure, and adsorption rate were decreased, while the molecular flexibility, interfacial film viscoelasticity, and interfacial protein content were increased. Meanwhile, LF-EGCG HIPPE possessed reduced droplet size, increased ζ-potential and stability. Rheology showed the viscoelasticity, structural recovery and gel strength of LF-EGCG HIPPE were improved, giving HIPPE inks better 3D printing integrity and clarity. Moreover, the free fatty acids (FFA) release of LF-EGCG HIPPE (62.6%) was higher than that of the oil group (50.1%). Therefore, covalent treatment effectively improved the interfacial properties of protein particles and the stability of HIPPEs. The macroscopic properties of HIPPEs were positively regulated by the interfacial properties of protein particles. The result suggested that the stability of emulsions can be improved by regulating the interfacial properties of particles.

Nanoparticles are used as fillers to improve the properties of biopolymers , and their particle size is an important parameter. This work aims to investigate the effect of particle size of isoreticular metal-organic framework-3 (IRMOF-3) on the mechanical, physical, and release properties of sodium alginate (SA)-based composite active film. In our study, IRMOF-3 with six different particle sizes was synthesized by introducing additives. IRMOF-3 loading with carvacrol (IRMOF-3/CA nanoparticles) was incorporated into the SA matrix to prepare the composite film . The characterization and testing results of films showed that the particle size of nanoparticles affected the physical morphology and chemical structure of the film. Especially smaller nanoparticles uniformly dispersed into the SA matrix more easily, forming a denser and more stable spatial network structure with SA, which could more significantly improve the tensile strength , water vapor barrier, and hydrophobic properties of the film ( P < 0.05). In addition, the CA release rate from the active film could be significantly reduced by about 33.90 % even when the smallest particle size of the IRMOF-3/CA nanoparticles was added. Therefore, when IRMOF-3/CA is used as the nano-filler to develop SA-based active film, its particle size has a potential influence on the properties of the film.
