Cognitive impairment in schizophrenia occurs in the early stages of the disease and is closely associated with prognosis. Alleviation of cognitive impairment in schizophrenia faces major challenges owing to the lack of preventive and therapeutic drugs that are novel and effective. Urolithin A (UA) is a gut microbial metabolite of ellagic acid that has demonstrated neuroprotective effects in multiple neurological disease models. Nonetheless, the neuromodulatory role of UA in schizophrenia is yet to be elucidated. Wistar rat pups were separated from their mothers for 24 h on postnatal days (PNDs) 9–10 to establish an early-life stress model. The pups were pretreated with UA at different administration times (2, 4, and 6 weeks) and doses (50, 100, and 150 mg/kg) from adolescence (PND29). Behavioral tests were performed after the end of the administration. Subsequently, hippocampal samples were collected for histopathological and molecular evaluations. Male offspring rats subjected to maternal separation exhibited increased sensitivity to prepulse inhibition and cognitive impairment, accompanied by severe neuroinflammation and impaired neurogenesis. However, UA attenuated maternal separation-induced prepulse inhibition deficits and cognitive impairments and restored hippocampal neurogenesis in a dose-dependent manner. Furthermore, UA pretreatment preserved dendritic spine density, synapses, and presynaptic vesicles. In addition, it exerted anti-inflammatory effects by inhibiting microglial activation and expression of the proinflammatory cytokines tumor necrosis factor-α, interleukin-6, and interleukin-1β. Potential mechanisms included upregulation of brain-derived neurotrophic factor protein expression and activation of the extracellular signal-regulated kinase signaling pathway. This study is the first preclinical evaluation of the effects of UA on cognitive impairment in schizophrenia. The findings suggest that changes in cognitive function linked to schizophrenia are driven by the interaction among neuroinflammation, neurogenesis, and synaptic plasticity and that UA has the potential to reverse these processes. These observations provide evidence for future clinical trials of UA as a dietary supplement for preventing schizophrenia.

Focused ultrasound ablation surgery (FUAS) is a minimally invasive treatment option that has been utilized in various tumors. However, its clinical advancement has been hindered by issues such as low safety and efficiency, single image guidance mode, and postoperative tumor residue. To address these limitations, this study aimed to develop a novel multi-functional gas-producing engineering bacteria biological targeting cooperative system. Pulse-focused ultrasound (PFUS) could adjust the ratio of thermal effect to non-thermal effect by adjusting the duty cycle, and improve the safety and effectiveness of treatment.The genetic modification of Escherichia coli ( E.coli ) involved the insertion of an acoustic reporter gene to encode gas vesicles (GVs), resulting in gas-producing E.coli (GVs -E.coli ) capable of targeting tumor anoxia. GVs -E.coli colonized and proliferated within the tumor while the GVs facilitated ultrasound imaging and cooperative PFUS. Additionally, multifunctional cationic polyethyleneimine (PEI)-poly (lactic-co-glycolic acid) (PLGA) nanoparticles (PEI-PLGA/EPI/PFH@Fe 3 O 4 ) containing superparamagnetic iron oxide (SPIO, Fe 3 O 4 ), perfluorohexane (PFH), and epirubicin (EPI) were developed. These nanoparticles offered synergistic PFUS, supplementary chemotherapy, and multimodal imaging capabilities.GVs -E.coli effectively directed the PEI-PLGA/EPI/PFH@Fe 3 O 4 to accumulate within the tumor target area by means of electrostatic adsorption, resulting in a synergistic therapeutic impact on tumor eradication.In conclusion, GVs -E.coli -mediated multi-functional nanoparticles can synergize with PFUS and chemotherapy to effectively treat tumors, overcoming the limitations of current FUAS therapy and improving safety and efficacy. This approach presents a promising new strategy for tumor therapy. Graphical

Background Ursodeoxycholic acid (UDCA), traditionally recognized for its hepatoprotective effects, has also shown potential in protecting kidney injury. This study aimed to evaluate the protective effects of UDCA against sepsis-induced acute kidney injury (AKI) and to elucidate the underlying mechanisms.Methods Sixty male C57BL/6 N mice were utilized to establish a sepsis-induced AKI model through intravenous injection of lipopolysaccharides (LPS, 10 mg/kg). UDCA (15, 30, and 60 mg/kg) was administered intraperitoneally once daily for 7 days before LPS injection. Kidney injury was evaluated by HE staining and biochemical markers, including serum creatinine (Cr), blood urea nitrogen (BUN), urinary protein, neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), N-acetyl-β-D-glucosaminidase (NAG), and retinol binding protein (RBP). Oxidative stress parameters and nuclear factor erythroid 2-related factor 2 (Nrf2)/ heme oxygenase-1 (HO-1) pathway, pro-inflammatory cytokines and nuclear factor-kappa B (NF-κB) pathway were also evaluated. Additionally, HK-2 cells were treated with LPS in vitro, and cell viability and apoptosis were detected using CCK-8 kit and flow cytometer, respectively.Results UDCA significantly attenuated LPS-induced renal histopathological damage and improved renal function, as evidenced by reduction in serum Cr, BUN, and urinary protein levels. UDCA also up-regulated the protein expression of zonula occludens-1 (ZO-1) and Ezrin in the kidney, and reduced the urinary levels of NGAL, KIM-1, NAG, and RBP. Moreover, UDCA inhibited NF-κB p65 phosphorylation and reduced pro-inflammatory cytokines levels (TNF-α, IL-1β, and IL-6) in both serum and kidney. UDCA alleviated oxidative stress by activating the Nrf2/HO-1 pathway in the kidney. In vitro, UDCA reduced LPS-induced cell injury and apoptosis in HK-2 cells, with these protective effects being blocked by the Nrf2 inhibitor ML385.Conclusion sOur present study demonstrated that UDCA exerts protective effects against sepsis-induced AKI by attenuating oxidative stress and inflammation, primarily through the activation of the Nrf2/HO-1 pathway and inhibition of the NF-κB pathway. These findings highlight the therapeutic potential of UDCA in preventing sepsis-induced AKI.

Seawater electrolysis driven by offshore renewable energy is a promising avenue for large-scale hydrogen production but faces challenges in designing robust anodes that suppress surface chlorine reactions and corrosion at high current densities. Here we report a strategy by selectively docking PW 12 -polyoxometalate (PW 12 -POM) onto Fe sites of CoFe hydroxide anode to modulate the electronic structure of adjacent Co active centers and regulate Cl⁻/OH⁻ adsorption for efficient alkaline seawater oxidation. Our CoFe-based anode achieves low overpotentials, high catalytic selectivity, and notable durability, with continuous operation at 1 A cm⁻² for over 1300 hours and at 2 A cm⁻² more than 600 hours. Theoretical calculations and ex situ/in situ analyses reveal that PW 12 -POM coordination at Fe sites stabilizes Fe, suppresses its leaching, modulates Co acidity, promotes OH⁻ adsorption, and protects metal sites from Cl⁻ corrosion.

Aqueous zinc-iodine (Zn||I 2 ) batteries, recognized for their cost-effectiveness, safety, and environmental sustainability, are emerging as the next-generation energy storage technologies. However, capacity degradation arising from the detrimental parasitic reactions at both the negative electrode and positive electrode interfaces presents substantial challenges for the practical implementations of Zn||I 2 batteries. Herein, we develop zwitterion-mediated interface chemistry to modulate the interface reactions using the zwitterion of 1-butylsulfonate-3-methylimidazolium (BM) as an electrolyte additive. At the negative electrode, the alignment of electric field-oriented BM molecules creates a dynamic dual-asymmetry interface, facilitating homogeneous Zn deposition and protecting the Zn metal electrode from the water and corrosive polyiodides. At the positive electrode, the reconfigured solvation configuration of iodide ions, involved by BM molecules, deactivates the interface reaction associated with the I 2 dissolution and polyiodide formation. Consequently, Zn||I 2 batteries with BM additive demonstrate enhanced rate capability (135.5 mAh g −1 at 20.0 A g −1 ) and extended durability (capacity retention of 91.9% after 50,000 cycles at 10.0 A g −1 ). The zwitterion-mediated interface chemistry effectively tackles the insurmountable challenges of aqueous Zn||I 2 batteries, facilitating their reliable and practical implementation.

Natural biological tissues exhibit different mechanical and surface properties. These disparate features make their connections with engineering materials quite difficult due to the lack of universal methods for tuning the interfacial bonding over a wide range. However, the precise control of interfacial properties, including modulus and adhesion on diverse biological tissues, requires overcoming multiple inherent and external barriers. Here we propose an interface-enhanced strategy by spatial and temporal anchoring of magnetic nanostickers for controlled bioadhesive properties. Fully exploiting the interactions from nanostickers by remote control enables the attached patch to achieve extremely high adhesion energy ( ~ 1250 J m -2 ) and interfacial fatigue resistance with a threshold of ~50 J m -2 , at a very low area density of nanostickers (4 μg/mm 2 ). The controlled interfacial properties as well as space and time for anchoring, lead to comprehensively tunable bioadhesion on diverse tissues such as skin, intestine, liver, and kidney, which are strongly desired in biomedical applications. Integration with fragile tissues in female Sprague-Dawley rats for 10 days further demonstrates that the anchored biointerface can adapt to the in vivo environment and promote postoperative recovery. The biointerface bridged by intelligent nanostickers prompts the methodology for bioadhesion towards controllable orientation.

Developing room-temperature phosphorescent (RTP) materials with microscale periodic structures presents a promising prospect for future optical applications but remains challenging due to the complex integration of luminescent and structural components. Herein, we present a strategy for large-scale production of RTP silica nanospheres (RTP SiO 2 NPs) with a low dispersity in size using a modified Stöber method, where organic molecules are embedded in silica networks and subsequently undergo in-situ carbonization, aggregation and crystallization to form phosphorescent carbon dots under high-temperature calcination. These NPs can self-assemble into photonic crystal (PC) structures, enabling the straightforward integration of structural color, fluorescence (FL) and RTP to achieve multimodal luminescent properties. The angle-dependent photonic bandgap (PBG) generated by the physical periodic structure modulates light propagation in RTP PC gels, creating FL and RTP angle-dependent chromatic responses. Temperature-induced refractive index changes between SiO 2 and the liquid matrix further enable dynamic control of light-scattering states, significantly altering transmittance and emission intensities of FL and RTP. This fusion of physical photonic structures with luminescence offers potential approach for constructing advanced multimodal luminescent devices.

Fluorine-doped carbon dots (F-CDs) are prepared through a one-pot hydrothermal method starting from ciprofloxacin, exhibiting a bright blue emission at 453 nm under the optical wavelength of 358 nm. The sensitive sensor for detecting Cu 2+ is established based on the fluorescence quenching of F-CDs, which is attributed to the static quenching caused by the formation of non-luminescent complexes between them. The limit of detection (LOD) is 46.2 nM. Meanwhile, a portable fluorescence sensor based on a lateral flow test strip (LFTS) has been developed for practical applications, which allows real-time monitoring of Cu 2+ with a satisfactory limit of detection (LOD) of 69.7 nM in a good linear range of 0.0697–50 μM. In addition, the identification of latent fingerprints (LFPs) based on F-CDs has been developed with the assistance of MATLAB, realizing high-performance fingerprint visualization and recognition. The results serve to underscore that the synthesized F-CDs not only provide a new tool for Cu 2+ detection in real samples, but also show great potential for LFPs visualization and information identification.

Neurotransmitters (NTs) are essential for modulating nerve signal transmission in the spinal cord, and this study aims to develop a highly sensitive, rapid, and accurate method for analyzing NTs in rat spinal cord tissue. This advancement is crucial for improving clinical diagnosis and management of neurological disorders. Ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-QqQ/MS 2 ) in conjunction with ultra-ionic liquid dispersive liquid-liquid microextraction (UA-MIL-DLLME) were employed to extract 20 NTs. Among the two magnetic ionic liquids (MILs) tested, [P 6,6,6,14 ] 2 [CoCl 4 ] was chosen as the extraction solvent due to its distinct properties, including visual recognition, paramagnetism, and high extraction efficiency. The method features efficient magnetic separation using an external magnetic field. Meanwhile, the color of the ionic liquid itself makes the extraction process easier to observe. To enhance extraction efficiency, the hydrophilic ionic liquid [BMIM]BF 4 was utilized as the dispersion solvent, and parameters such as MIL type, solvent amount, extraction time, salt concentration, and pH were systematically optimized. The resulting method demonstrated high precision, a broad linear range, and low detection limits, with satisfactory recovery rates for all 20 NTs analyzed. Given its exceptional analytical performance, this technology has broad prospects in the analysis of the nervous system.

Although there have been remarkable advances in the treatment of hepatocellular carcinoma (HCC), the prognosis remains poor in those with advanced stage and more effective therapeutic options are urgently needed. Lenvatinib (Len), a multiple receptor tyrosine kinase inhibitor, is an emerging molecular targeted agent for HCC, whose immunomodulatory activities have been investigated. However, Len utilization is limited because of its low metabolic stability, poor bioavailability and dose-dependent toxicity, rendering its direct use insufficient for immune modulation. Stimuli-responsive nanoparticles, which are drug-targeted delivery platforms for on-demand drug release, facilitate deeper and uniform tumour penetration, providing alternative solutions to overcome current limitations. Ultrasound (US) exhibits superior tissue penetration abilities and can produce reactive oxygen species (ROS) at the tumour site to treat deeper tumours. In addition, US serves as an excellent and selective drug delivery mediator for tumour treatment. Herein, we designed US-triggered lenvatinib nanoparticles (Len-RNPs) for selective drug delivery that utilize US-triggered ROS to induce in situ oxidation reactions, resulting in nanoparticle disintegration. Len-RNPs mitigate the toxicity of Len and effectively trigger robust systemic anti-tumour immune responses in a H22 tumour model, resulting in a tumour suppression rate of 95.7%, with 60% of mice being cured. Our study elucidates a novel and precise strategy of combining Len and US therapy for enhanced HCC immunotherapy.

Background The oil palm ( Elaeis guineensis ) is a crucial agricultural commodity, yielding the highest oil output among oil-bearing crops. Despite its significance, productivity challenges persist due to genetic and environmental factors. This study breaks new ground by mapping tRNA modifications in oil palm, exploring their roles during fruit ripening, an area not extensively studied in non-model crops. Results Utilizing advanced RNA mass spectrometry techniques, we identified 48 distinct tRNA modifications across 88 sites, alongside 164 genes associated with tRNA modifying enzymes. This comprehensive mapping reveals the decreasing nature of most tRNA modifications during fruit development, except for adenosine 2’-O methylation (Am). It hints at a gradual weakening of protein translation quality control and highlights a unique role for Am during fruit ripening. Additionally, lipidomic analysis tracked 674 lipids in oil palm fruits, indicating a correlation between tRNA modifications and the accumulation of specific lipids. Conclusions This study mapped tRNA modifications in oil palm for the first time and showed the diversity of dynamic changes in tRNA modifications as the fruits develop.
