Objective To investigate the mechanism in the progression of decreased ovarian reserve (DOR). Methods Three-month-old female SD rats were employed and randomly divided into the model group and the normal group. The model group was intraperitoneally injected with 4-vinylcyclohexene diepoxide (VCD). Thereafter, blood sample from the abdominal aorta was taken, and rats were sacrificed, and ovarian tissues were obtained by laparotomy. Results HE staining results revealed that the model group exhibited significantly reduced ovarian volume, increased follicular atresia, and decreased quantities of growing follicles and corpus luteum, thereby indicating degraded reserve function of ovarian. TEM images revealed that prominent autophagic vacuoles could be observed in the model group, accompanied by the mitochondria shrinkage and generation of the autophagosome. The expression of Pink1, Parkin, BNIP3L and LC3II genes in ovaries of the model group was significantly higher than those of the normal group ( P < 0.05). In addition, the protein expression of Pink1, Parkin, BNIP3L and LC3II in ovaries of the model group were higher than those of the normal group ( P < 0.05). The expression of Fe 2+ and GSH in oocytes of the model group was higher than those of the normal group ( P < 0.05). The expression of FTH1 and GPX4 in oocytes of the model group was significantly higher than those of the normal group ( P < 0.05). Conclusions Mitochondrial autophagy and ferroptosis may participate in the progression of decreased ovarian reserve (DOR).

Directly growing oxides on the surface of liquid metal (LM) offers a novel strategy to effectively integrate flexible conductive substrate with semiconductive layer for functional devices including photodetectors. Gallium-based liquid metal with native oxides surface typically demonstrates such LM/semiconductor construction with attractive photoelectric responsivity, however, the relevant photo-electrode lacking efficient response to visible light due to the wide band-gap of Ga-oxides. This paper presents a straightforward fabrication route containing printing and in-situ reaction growing for the preparation of liquid metal functionalized with narrow-band gap semiconductor ( e.g. , Cu 2 O). The resulting LM/metal-oxides heterostructure exhibits a well-matched liquid–solid contact and good interfacial charge transfer between the soft conductive substrate and active surface components. Characterizations including scanning electron microscopy (SEM), Raman spectroscopy, and UV–visible absorption spectroscopy confirm the successful preparation of the Cu 2 O thin layer with an expanded absorption spectrum range. The as-fabricated photoelectrode consisted of LM-Cu 2 O, through photoelectrochemical (PEC) tests, presents fast photo-responsibility under the simulated sunlight illumination and self-powered capability. Specifically, the LM-Cu 2 O based PEC photodetector shows maximum photoresponsivity of − 70 μA/W and photocurrent density of − 9.5 μA/cm 2 at a bias voltage of 0 V. Our results provide a general method for the design and manufacture of novel photodetectors.

Mimicking natural photosynthesis to convert CO 2 with H 2 O into value-added fuels achieving overall reaction is a promising way to reduce the atmospheric CO 2 level. Casting the catalyst of two or more catalytic sites with rapid electron transfer and interaction may be an effective strategy for coupling photocatalytic CO 2 reduction and H 2 O oxidation. Herein, based on the MOF ∪ COF collaboration, we have carefully designed and synthesized a crystalline hetero-metallic cluster catalyst denoted MCOF-Ti 6 Cu 3 with spatial separation and functional cooperation between oxidative and reductive clusters. It utilizes dynamic covalent bonds between clusters to promote photo-induced charge separation and transfer efficiency, to drive both the photocatalytic oxidative and reductive reactions. MCOF-Ti 6 Cu 3 exhibits fine activity in the conversion of CO 2 with water into HCOOH (169.8 μmol g −1 h −1 ). Remarkably, experiments and theoretical calculations reveal that photo-excited electrons are transferred from Ti to Cu, indicating that the Cu cluster is the catalytic reduction center.

Organic thermoelectric fibers have great potential as wearable thermoelectric textiles because of their one-dimensional structure and high flexibility. However, the insufficient thermoelectric performance, high fabrication cost, and mechanical fragility of most organic thermoelectric fibers significantly limit their practical applications. Here, we employ a rapid and cost-effective wet-spinning method to prepare dimethyl sulfoxide-doped poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) fiber bundles, followed by rational post-treatment with concentrated sulfuric acid (98% H 2 SO 4 ) to enhance their thermoelectric performance. The wearable fiber bundles composed of multiple individual PEDOT:PSS fibers have effectively reduced resistance and overall high tensile strength and stability. Rational treatment with H 2 SO 4 partially removes excessive PSS, thereby increasing the electrical conductivity to 4464 S cm ‒1 , while the parallel bundle is also a major factor in improving the power factor of up to 80.8 μW m ‒1 K ‒2 , which is super-competitive compared with those of currently published studies. Besides, the thermoelectric device based on these fiber bundles exhibits high flexibility and promising output power of 2.25 nW at a temperature difference of 25 K. Our work provides insights into the fabrication of all-organic flexible high-conductivity textiles with high thermoelectric properties. Graphical

The applications of nanomaterials in regenerative medicine encompass a broad spectrum. The functional nanomaterials, such as Prussian blue and its derivative nanoparticles, exhibit potent anti-inflammatory and antioxidant properties. By combining it with the corresponding scaffold carrier, the fusion of nanomaterials and biotherapy can be achieved, thereby providing a potential avenue for clinical treatment. The present study demonstrates the fabrication of a Mesoporous Prussian blue nanoparticles (MPBN) functionalized Inverse Opal Film (IOF) neuroconduit for peripheral nerve repair through reverse replication and freeze-drying techniques. The binding of MPBN to the neuroconduit can effectively decreasing reactive oxygen species and inflammatory factors in the vicinity of the residual nerve, thereby providing protective effects on the damaged nerve. Furthermore, comprehensive behavioral, electrophysiological, and pathological analyses unequivocally substantiate the efficacy of MPBN in increasing nerve structure regeneration and ameliorating denervation-induced myopathy. Moreover, MPBN enhances the antioxidant capacity of Schwann cells by activating the AMPK/SIRT1/PGC-1 pathway. The findings suggest that MPBN, a biocompatible nanoparticle, can safeguard damaged nerves by optimizing the microenvironment surrounding nerve cells and augmenting the antioxidant capacity of nerve cells, thereby facilitating nerve regeneration and repair. This also establishes a theoretical foundation for exploring the integration and clinical translation between nanomaterials and biotherapy.

Objective Amorphous solid dispersion (ASD) is widely utilized to enhance the solubility and bioavailability of water-insoluble drugs. However, conventional experimental approaches for ASD development are often resource-intensive and time-consuming. Machine learning (ML) algorithms have great potential to predict ASD formulations but face the challenge of extensive data to construct reliable models. Current study aims to predict the formation of both binary and ternary ASD by combined high-throughput screening (HTS) and ML approaches. Methods Micro-quantity HTS was conducted to generate 1272 binary and ternary solid dispersions using solvent evaporation method. The Powder X-Ray Diffraction (PXRD) was used to characterize the amorphous state of formulations. The results indicated that 188 formulations successfully formed amorphous solid dispersions (ASDs), while 1084 resulted in crystalline formations. Models development employed nested cross-validation with four algorithms: Light Gradient Boosting Machine (LGBM), Random Forest (RF), Support Vector Machine (SVM), and Multi-Layer Perceptron (MLP). Results The RF model for ASD formation achieved 96.7% accuracy on the in-house HTS dataset, with a precision of approximately 87.9% and an F1 score of 83.6%. Furthermore, the RF model trained with milligram-scale HTS experimental data could effectively predict the large-scale ASD formulations from the literature, highlighting its promise as a powerful tool for advancing ASD prediction. Conclusion In summary, the combination of HTS experiments and ML techniques provides a valuable reference framework for ASD development, greatly minimizing both time and material usage in the selection of formulations during the early stages of drug discovery with a limited quantity of API. Graphical The workflow of this study involves a micro-quantity HTS experiment that generated over a thousand homogeneous data points for ML model development. The RF model demonstrated strong performance on a large-scale external dataset for ASD prediction, significantly saving time and material usage in formulation development, particularly during early drug discovery.

Antibiotic contamination has emerged as a global challenge, increasing antibiotic resistance and threatening human health and ecosystems. Bioremediation using microorganism offers sustainable methods to degrade such pharmaceutical contaminants. However, these microorganisms exhibit reduced activity under high-stress conditions, and are difficult to recycle and potentially leak into environment as microbial pollutions. Here we report bioprinted retrievable microalgae hydrogel networks (MHNs) by confining living microalgae in double-network hydrogels, which achieves enhanced antibiotic degradation (>99.3%) and recyclable ability. Particularly, coating MHN with tannic acid (MHN@TA) generates a semipermeable membrane to prevent the leakage of microalgae (<0.7% for 7 days), ensuring the containment of potential microbial biohazards. The biohybrid system protects the biological activity of microalgae, enabling antibiotic degradation up to 400 mg L −1 . Free-standing MHN@TA fencing systems are also manufactured to demonstrate their practical applications. This study provides insights of microalgae-material interactions in bioremediation and offers design rationales for biohybrid systems.

Clusters have proven useful models to elucidate the correlation between macroscopic properties and microstructures. However, the actinide clusters still remain much less developed compared to the splendid and systematic works of other members of this family. Here we show the synthesis of a tetra-shell mixed-metal cluster [ThO 8 @Th 12 (OH) 24 @Ni 6 (H 2 O) 18 @(sba) 12 ] (IHEP-25, H 2 sba: 2-sulfobenzoic acid) with the strategic introduction of competitive Ni 2+ ions. A cluster-based framework (IHEP-28), featuring a 2D honeycomb network and demonstrating excellent stability, has been constructed through the multistage assembly of IHEP-25, facilitated by the introduction of cationic cluster [Na 4 (OH) 3 (H 2 O) 3 ] + . IHEP-28 acts as a highly effective visible light-driven photocatalyst for CO 2 reduction. This study demonstrates that the incorporation of heterometal ions not only alters the hydrolysis patterns of actinide metal ions, resulting in the formation of new actinide clusters, but also broadens their potential applications.

It is of great practical significance to explore and prepare cheap, high-performance, and stable catalysts for oxygen reduction reaction (ORR), but it is still in progress at present. Herein, a straightforward evaporation–pyrolysis strategy is designed for the preparation of 3D porous electrocatalysts (denoted as \(\textrm{Fe}-\textrm{Co}-\textrm{NC}\) , which represented carbonization products at °C) made of carbon nanoparticles combined with metallic Fe-Co-doped N-enriched bridged carbon nanotube by carbonization of a pristine ZIF8 as highly efficient and durable ORR electrocatalysts. The obtained Fe–Co–NC structure possesses 3D open porous texture, abundant active sites, desired nitrogen bonding type, and high specific surface area, providing them with excellent ORR activity. The optimal performing \(\textrm{Fe}-\textrm{Co}-\textrm{NC}\) catalyst presents an outstanding ORR performance in terms of a high onset potential ( \(\textrm{E}_{\text{ onset } }\) ) of 0.96 V (vs. RHE) and half-wave potential ( \(\textrm{E}_{1 / 2}\) ) of 0.86 V (vs. RHE), respectively, possible to rival those of the commercially available \(\textrm{Pt} / \textrm{C}\) in an alkaline electrolyte solution. Besides, the \(\textrm{Fe}-\textrm{Co}-\textrm{NC}\) catalyst manifests better stability than those of commercially available \(\textrm{Pt} / \textrm{C}\) , which is of importance for the optimization and characterization of novel electrocatalysts originated from non-precious metals.

The nanocomposite materials are highly promising candidates for adsorption applications in dyed wastewater due to their distinctive structural properties. In this work, the nanocomposite hybrids of UiO-66@GO were first synthesized by specifically anchoring Zr-based metal organic framework (MOF) of UiO-66 onto graphene oxide (GO) nanolayer through solvothermal method. Then the composite matrix microspheres (CMMs) of UiO-66@GO were subsequently prepared by embedding the obtained UiO-66@GO nanocomposite into sodium alginate (SA) microspheres through self-assembly cross-linking process. Finally, the prepared UiO-66@GO CMMs were applied for the adsorption of organic dye pollutant and showed efficient water purification performance. As a result, the UiO-66@GO CMMs exhibited selective cationic dye adsorption for Rhodamine B (RhB + ). The experimental results revealed that the adsorption kinetics followed by the pseudo-second-order (PSD) model with rate constant k 2 = 0.95 × 10 –3 g mg −1 min −1 , and the thermodynamics followed by the Langmuir model with adsorption capacity of 345.66 mg mg −1 . Notably, the UiO-66@GO CMMs demonstrated excellent adsorption removal of a significant removal efficiency of 98% towards 10 ppm Rh-B and a rapid adsorption response time of ~ 5 min. Meanwhile, the UiO-66@GO CMMs maintained long-term stability with adsorption efficiency > 95% over 30 days and effective reuse with resorption efficiency > 90% using DMF-H₂O as eluent. In this study, SA has served as a porous supporting matrix to immobilize UIO-66@GO nanoparticles, having mitigated issues of aggregation and leaching common to nanoscale adsorbents while improving reusability. The synergistic effect between UIO-66 and GO has further enhanced pollutant adsorption capacity, demonstrating significant potential for dye wastewater treatment applications.

The effective treatment of Alzheimer’s disease (AD) is challenging because of its complex and controversial pathological mechanisms. Moreover, multiple barriers, such as the blood–brain barrier (BBB), reduce drug delivery efficiency. Microglia-related neuroinflammation has recently attracted increasing attention as a possible cause of AD and has become a novel therapeutic target. Therefore, overcoming the BBB and targeted delivery of anti-inflammatory agents to microglia seem to be effective practical strategies for treating AD. A large proportion of natural active extracts possess exceptional immunomodulating capabilities. In this study, the cooperative delivery of berberine (Ber) and palmatine (Pal) by transferrin-decorated extracellular vesicles (Tf-hEVs-Ber/Pal), which can cross the BBB and precisely target microglia, was performed. This nanosystem effectively cleared amyloid β-protein (Aβ) aggregates, significantly regulated the neuroinflammatory environment both in vitro and in vivo and markedly altered the behavior and improved the cognitive and learning abilities of AD model mice. The efficacy of a microglia-targeting combined therapeutic approach for AD was demonstrated, which broadens the potential application of Chinese herbal ingredients.Graphical abstract

Superhydrophobic fibrous materials are highly desirable for improving wearing comfort and protection however, constructing durable superhydrophobic fabrics with excellent moisture permeability and high resistance to water penetration remains a great challenge. Therefore, we present an efficient and facile approach to construct super-hydrophobic polyurethane/fluorinated polyurethane/SiO 2 (PU/FPU/SiO 2 ) nanofibrous membranes via the incorporation of electrospinning and hot-pressing. SiO 2 nanoparticles are incorporated into the PU/FPU nanofibers, creating a multi-level micro/nano-scale roughness. Specifically, the aggregation of composite nanofibers contributes to micro-roughness, while the addition of SiO 2 nanoparticles gives rise to nano-roughness. FPU has an extremely low surface energy. We intend to add FPU to boost the hydrophobicity of the membranes, so as to obtain super-hydrophobic characteristics. Moreover, we comprehensively study the effect of the SiO 2 nanoparticles concentration on the hydrophobicity of nanofibrous membranes and also discover the influence of heat treatment temperature on the porous structure of nanofibrous membranes. According to our design, the final membranes are anticipated to show a combination of an outstanding super-hydrophobic surface (water contact angle of 152°), good waterproof and breathable properties (high water vapor transmission rate of 7.9 kg m −1 d −1 and excellent hydrostatic pressure of 59 kPa). This indicates that PU/FPU/SiO 2 nanofibrous membranes have great potential for use in the next generation of protective fabrics. Graphical
