Vitamin D 3 (VD 3 ) is an essential fat-soluble micronutrient that regulates diverse biological processes. However, its long-term impact on avian intestinal development remains largely unknown. In this study, we detected that the VD 3 content was significantly lower in late-cycle production eggs (68 weeks old, termed “LP eggs”) compared to the peak-cycle production eggs (44 weeks old, named “PP eggs”) ( P < 0.05). Notably, the intestine index was reduced ( P < 0.05), and the intestinal expression of tight junction (TJ) proteins (Occludin and ZO-1) was decreased for chicks hatched from LP eggs versus those from PP eggs ( P < 0.05). Thus serial dosages of VD 3 (2.5, 5.0, or 7.5 μg VD 3 /egg) were injected into the amniotic cavity of embryos hatched from LP eggs on embryonic day 17 (E17). This intervention effectively improved hatchability, promoted intestinal development that persisted through 14-days post-hatch, and showed immuno-modulatory effects manifesting as Interleukin-6 ( IL-6 ) downregulation and Interleukin-10 ( IL-10 ) upregulation. Further in vivo and in vitro analysis revealed that VD 3 improved intestinal development by activating TJ-related genes ( P < 0.05), with vitamin D receptor (VDR) mediating these effects. Chromatin immunoprecipitation (ChIP) assays confirmed that 1,25-(OH) 2 D 3 strengthened VDR binding to promoter regions of Occludin and ZO-1 but decreased the interaction degree of VDR with the IL-6 promoter ( P < 0.05). These findings establish that in ovo injection of VD 3 is an efficacious perinatal intervention strategy, which significantly mitigates developmental constraints in late-phase poultry production through VDR-dependent intestinal barrier potentiation and immuno-homeostasis modulation.

With the increasing demand for the co-encapsulation and controlled delivery of bioactive compounds, the design of liquid-based carriers has garnered considerable attention. Vitamin D 3 and riboflavin sodium phosphate (RP) suffer from poor stability and low bioavailability; nevertheless, high internal phase Pickering emulsions (HIPPEs) feature a tunable microstructure that allows for effective compartmentalization of multiple components. In this study, HIPPEs stabilized by egg white peptide (EWP)-konjac glucomannan (KGM) co-assemblies were constructed as a versatile vehicle for the co-delivery of vitamin D 3 and RP. EWP-KGM co-assemblies were comprehensively characterized using multispectral techniques and structural analyses. The EWP@KGM co-assembly (mass ratio 10:5) exhibited enhanced emulsifying activity index (EAI: 15.12 m 2 /g, 3.74-fold higher than EWP) and emulsifying stability index (ESI: 736.60 min, 53-fold higher than EWP), attributed to increased interfacial thickness and steric hindrance. All HIPPEs demonstrated shear-thinning behavior, gel-like viscoelasticity (G′ > G″), and long-term storage stability. Under simulated gastrointestinal digestion, EWP-KGM-HIPPEs protected RP integrity and improved vitamin D 3 bioaccessibility. FFA release kinetics followed Korsmeyer-Peppas model, indicating anomalous transport driven by diffusion and matrix relaxation. This study presents a promising platform for the dual encapsulation of bioactives with contrasting polarities, paving the way for applications in nutraceuticals.

To enhance the bioaccessibility of vitamin D3 in fortified food systems, hydrodynamic cavitation, ultrasonic cavitation, and an ascorbic acid/hydrogen peroxide system were employed to generate free radicals that mediated the formation of gallic acid-soy protein isolate (GA-SPI) conjugates. The resulting conjugates were used to stabilize emulsions. The emulsion properties and their effects on vitamin D3 delivery were investigated. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) confirmed that covalent conjugation between GA and SPI was promoted by free radical generation in all three treatments. Compared with emulsions prepared with soy protein isolate alone, significant improvements were observed for emulsions stabilized by GA-SPI conjugates, including smaller particle size, higher absolute zeta potential, higher storage modulus, and improved storage stability and antioxidant capacity. These improvements were attributed to GA incorporation and the processing methods. More importantly, when used to encapsulate vitamin D3, bioaccessibility ranged from 53.36 ± 0.57% to 80.06 ± 0.12% for GA-SPI stabilized emulsions prepared by these methods, compared with the untreated group. These findings confirm that emulsion delivery performance can be improved by the three free radical-mediated treatments through promotion of polyphenol-protein conjugation.

Vitamin K 2 (VK 2 ) and vitamin D 3 (VD 3 ) can synergistically promote calcium absorption and reduce the prevalence of osteoporosis. Given their hydrophobicity and environmental sensitivity, stabilizing both these vitamins is pivotal for their application. In this study, we designed shellac-gliadin composites (SGCs) with favorable amphiphilicity, yielding a self-emulsifying delivery system (SEDS) upon mild mixing with eugenol. By increasing eugenol/SGCs mass ratio, SEDS was transformed from spherical to a network-like structure, forming tunable topological nanostructures with tailorable delivery performance and bioavailability. Based on the dual-step process, VK 2 was encapsulated during shellac-gliadin assembly, while VD 3 was co-encapsulated via self-emulsification. The generated dual-vitamin self-emulsifying system (DSEDS) improved the stability under UV-light and long-term storage for both vitamins with high encapsulation capacities of 48.05 and 9.36 mg/g for VK 2 and VD 3 , respectively. The dual-step strategy introduced a novel approach for loading various fat-soluble nutrients, with potential applications in food and nutrition industry.

1α,25-dihydroxyvitamin D 3 (1α,25(OH) 2 VD 3 ), the biologically active form of Vitamin D 3 (VD 3 ), plays a crucial role in a wide range of physiological processes. However, the efficient biosynthesis of 1α,25(OH) 2 VD 3 is hindered by the low activity of natural enzymes, poor solubility of substrate VD 3 , and its intracellular metabolic loss. Herein, we developed an integrated bioprocess by synergizing engineered dihydroxylase (CYP109A2-H) with a deep eutectic solvent (DES) based resting cell system to overcome these limitations. A semi-rational design strategy was employed to enhance the performance of the enzyme, which yielded several beneficial mutants including E81G that increased the catalytic titer by 43.6%. Concurrently, a DES resting cell system was constructed, wherein DES dramatically increased VD 3 solubility and resting cells eliminated metabolic loss. This synergistic strategy achieved a record-high 1α,25(OH) 2 VD 3 space–time yield of 33.15 mg·L −1 ·d −1 , establishing the most efficient single-batch bioconversion reported to date. This work provides a sustainable and efficient platform for 1α,25(OH) 2 VD 3 production and a general strategy for the biohydroxylation of hydrophobic compounds.

Although vitamin B12 (VB12) is an essential water-soluble vitamin for the human body, the adverse reaction by excessive use is also worth noting. Therefore, it is crucial to detect the accurate concentration of VB12. In this work, biomass-based carbon dots (BCDs) were prepared by a facile one-pot hydrothermal method from black rice and urea. Based on inner filter effect and static quenching mechanism, the BCDs suggested conspicuous sensitivity and specificity for VB12 detection. The linear ranges were 0.5–100 μM and 0–50 μM under dual fluorescence and colorimetric modes, respectively. Additionally, the obvious color change by addition of VB12 in BCDs solution ensured the feasibility of visual experiments with smartphone assistance. The portable determination system maintained exceptional operability, quick analysis and excellent precision. Combined with the outstanding performance in real samples, this study offers a novel tactic for pharmaceutical analysis based on fluorescence/colorimetric/visualization modes.

The pathogenesis of sarcopenia, a geriatric syndrome associated with chronic glucocorticoid exposure, involves redox homeostasis dysregulation of skeletal muscle. There is an urgent need for targeted therapeutic strategies. In this study, we developed a thermosensitive hydrogel composed of skeletal muscle-derived decellularized extracellular matrix, chitosan, and β-glycerophosphate. This multifunctional platform was co-encapsulated with a nuclear factor erythroid 2-related factor 2 (Nrf2) agonist (bardoxolone) and myoblast-derived exosomes to synergistically enhance muscle regeneration. The injectable hydrogel exhibited rapid sol-gel transition at 37 °C and sustained bardoxolone release kinetics. In dexamethasone (Dex)-induced C2C12 myoblasts, the hydrogel effectively normalized atrophic markers (muscle-specific RING finger protein 1, muscle atrophy F-box protein), while upregulating myogenic factors (myoblast determination protein 1, myosin heavy chain, myosin heavy chain 7, and myogenin). Intramuscular administration of the hydrogel in Dex-treated mice ameliorated sarcopenic manifestations through enhanced skeletal muscle mass, grip strength, weight-loaded swimming time, rotating rod time, and myofiber cross-sectional area. Mechanistically, the hydrogel restored mitochondrial impairment in Dex-treated myoblasts through Nrf2 pathway activation, evidenced by upregulated nuclear Nrf2, translocase of outer mitochondrial membrane 20, voltage dependent anion channel 1, and recovered oxygen consumption rate. Crucially, complete therapeutic efficacy ablation in both in vitro and in vivo Nrf2-knockout models confirmed Nrf2 as the central regulatory hub. This hydrogel integrates extracellular matrix-mimetic architecture, controlled molecular release kinetics, and exosome-mediated cytoprotection, establishing a therapeutic strategy for sarcopenia management.

Fungal unspecific peroxygenases (UPOs) can directly utilize H2O2 as an oxygen and electron donor for selective C–H bond oxyfunctionalization. However, long-time duration of genetic modification and expression in Pichia pastoris limited its quick evolution. Herein, we propose a novel structure-guided combinatorial evolution strategy(SBPCS) to accelerate the iterative cycle of multipoint mutagenesis for C25 hydroxylation of VD3 by AaeUPO. Through mutational screening of key residues within the substrate-binding pocket, combined with molecular dynamics (MD) simulations, we observed shortened distance and a stabilized dihedral angle between the substrate’s C25 atom and the heme Fe═O center. After two rounds of coevolution, a triple mutant (G195A/V244I/S272A, M3) was successfully obtained, demonstrating a 5.16-fold increase in C25-hydroxylation efficiency, with a increased the yield of 25(OH)VD3 from 45.8 to 354.40 mg/L. Our study elucidate how the geometry of the heme-VD3 complex effect catalytic efficiency during selective hydroxylation and guided a rational design for accelerating AaeUPO coevolution toward VD3 C25-hydroxylation.

In this study, carboxymethyl cellulose (CMC) and wheat glutenins (WGs) formed complex structures (CWs) featuring nanoparticles (∼160 nm) fixed at the junctions of fibril networks (50 nm in thickness) with numerous smaller nanoparticles attached to the fibril trunks. The complexation was performed by dissolving CMC and WGs in an alkaline solution (pH 12.0) followed by neutralization. Fluorescence study and Fourier transform infrared spectroscopy indicated that electrostatic forces initiated the binding of WGs to CMC, while hydrophobic attractions contributed to the growth of WG nanoparticles on CMC fibrils. This enabled sufficient dispersing of WGs that can be harnessed as binding sites for vitamin D 3 (VD 3 ). Importantly, the microstructures of CWs can be delicately controlled by the substitution degree (DS) of carboxymethyls. Consequently, the stability of VD 3 against long-term storage and UV radiation by CWs was improved by 77.87–92.55% and 113.13–166.45%, respectively, which were highly dependent on DS. Furthermore, the CWs can realize sustained release of VD 3 in simulated gastrointestinal fluid controlled by varied DS. This study provided a facile and effective approach for advanced utilization of WGs with potential applications in the development of novel food structures and formulation of functional ingredients.

Micellar hydrogels formed by direct self-assembly of natural compounds have attracted widespread attention as delivery systems owing to their distinctive structures, excellent biocompatibility and simple preparation methods. Herein, we report on glycyrrhizic acid (GA), which is directly self-assembled into micellar hydrogels to encapsulate curcumin (Cur) through non-covalent interactions without excipients or structural modifications. Owing to their reversible non-covalent interactions, the micellar hydrogels have outstanding shear-thinning, self-healing ability and temperature-responsive behavior. Notably, the mechanical properties and release rates of the micellar hydrogels can be easily tuned by adjusting the concentration of GA. Furthermore, the [email protected] micellar hydrogels have exhibited superior stability, remarkable biocompatibility and better antioxidant properties than free Cur, benefiting from improved solubility and stability. In brief, this micellar hydrogel inherits the advantages of both micelles and hydrogels: it has characteristics of micelles, naturally encapsulates Cur and has the ability of hydrogels to control long-term release. We believe this study will offer an innovative strategy to deliver Cur efficiently.

Poor water solubility is one of the main adverse factors for vitamin D 3 to be used as a fortifier in water-soluble food system. In this study, a phase transformation based nanoemulsion fabrication process was developed to encapsulate vitamin D 3 with Tween 80 and Span 80 as a composite surface-active surfactant (named as Vit D 3 NEs). The encapsulation efficiency of vitamin D 3 in resultant oil in water nanoemulsions reached 99.9%. The prepared Vit D 3 NEs was spherical with average particle size of 391.47 ± 12.89 nm, polydispersity index of 0.23–0.31, and endothermic temperature of 127.1 ℃. Results of FTIR indicated that hydrophobic, electrostatic and hydrogen bond interactions were involved in Vit D 3 NEs fabrication. Compared to un-encapsulated Vit D 3 (bare Vit D 3 ), Vit D 3 NEs displayed higher stability under gastric digestion, and sustained release under intestinal digestion. The cumulative release of Vit D 3 reached 69% after 5 h of intestinal digestion. Further, Vit D 3 NEs demonstrated stronger thermal stability than the bare Vit D 3 at 40–60 °C, and the first-order kinetics was well fit to describe its thermal degradation . Our work suggests a new insight into the application of Vit D 3 NEs stabilized by Tween 80 and Span 80 in food industry.

Doping Ag-enhanced and glutathione-stabilized Au nanoclusters (GSH–Ag/AuNCs) were prepared by the one-step ultraviolet radiation combined with microwave heating method. The effects of the molar ratio of Au–Ag and different types of energy suppliers on the fluorescent performance of GSH–Ag/AuNCs were studied in detail. After that, a new ratio fluorescent probe (RF-probe) based on the mixing of GSH–Ag/AuNCs with carbon dots (CDs) was designed for sensitive and selective determination of copper gluconate (CG) and cupric sulfate (CS). For the CDs–GSH–Ag/AuNCs RF-probe, the fluorescence (FL) of CDs (at 440 nm) and that of alloy nanoclusters (NCs) (at 605 nm) were, respectively, unaffected and strongly quenched in the presence of CG/CS at λ ex = 3 7 0 nm coming from the dynamic quenching process. Corresponding linear ranges and limit of detection (LOD) of the RF-probe for the CG/CS assay were estimated to be 0.17–6.20/0.17–5.62 μ mol/L and 16.80/15.95 nmol/L, respectively. Furthermore, the proposed RF-probe was successfully used for the assays of CG in CG tablets and CG additive, and CS in infant formula and CS additive, respectively.
