These carbon dots establish an innovative technical framework by integrating dual "detection-remediation" functionalities through eco-friendly synthesis and high-value conversion of medicinal-edible plants and agroforestry waste. Their core advantages originate from structural templating effects induced by natural functional groups (polyphenols, amino acids) in plant precursors combined with heteroatom self-doping, which synergistically optimizes optical properties. This combination achieves quantum yields ranging from 3.06% to 84.9% and detection sensitivities spanning nanomolar to micromolar concentrations. In pollutant detection applications, P-CDs enable ultrasensitive identification of heavy metals (Hg^(2+) , Cu^(2+) , Fe^(3+) ) and organic contaminants (pesticides, antibiotics) through multi-mechanistic interactions including static quenching (SQ), dynamic quenching (DQ), and F rster resonance energy transfer (FRET). However, technological translation faces critical challenges including quantum yield heterogeneity (>40-fold variation), matrix interference in complex environmental samples (signal drift exceeding 12%), and scalability-related process inconsistencies. Future research priorities should focus on three key areas: standardization of synthesis protocols, development of surface passivation strategies ( e.g. , SiO_(2) encapsulation), and optimization of heterojunction designs to enhance interference resistance. The integration of in situ characterization techniques (particularly X-ray absorption spectroscopy) with machine learning-driven parameter optimization could significantly refine detection-remediation synergies. Concurrently, establishing a comprehensive lifecycle assessment framework becomes imperative for evaluating environmental impacts and scalability potential. This technology pioneers a sustainable paradigm for pollution control by bridging the gap between nanomaterial innovation and industrial deployment, thereby accelerating progress toward global ecological security objectives.展开更多

PENs are minimally cytotoxic to healthy tissues, with which they show excellent biocompatibility, and are biased towards tumors by targeting specific tissues through special endocytosis mechanisms. Thus, the use of these PENs may expand the scope of drug therapies while reducing the off-target effects.In this review, we summarize the fundamental features and bioactivities of PENs extracted from the grape, grapefruit, ginger, lemon, and broccoli and discuss the applications of these particles as therapeutics and nanocarriers.展开更多

However, it is unclear how saline–alkali land reclamation(converting saline–alkali land into cultivated land) affects soil C storage.We collected 189 adjacent pairs of salt-affected and cultivated soil samples(0–30 cm deep) from the Songnen Plain, eastern coastal area, Hetao Plain, and northwestern arid area in China. Various soil properties, the soil inorganic C(SIC), organic C(SOC), particulate organic C(POC), and mineral-associated organic C(MAOC) densities, and plant-and microbial-derived C accumulation were determined.Saline–alkali land reclamation inconsistently affected the SIC density but significantly(P < 0.001)increased the SOC density. The SOC, POC, and MAOC densities were predicted well by the integrative soil amelioration index. Saline–alkali land reclamation significantly increased plant-derived C accumulation and the plant-derived C to microbial-derived C ratios in all saline–alkali areas, and less microbial transformation of plant-derived C(i.e., less lignin degradation or oxidation) occurred in cultivated soils than salt-affected soils. The results indicated that saline–alkali land reclamation leads to plant-derived C becoming the dominant contributor of SOC storage. POC storage and MAOC storage were strongly linked to plant-and microbial-derived C accumulation, respectively, caused by saline–alkali land reclamation.Our findings suggest that saline–alkali land reclamation increases C storage in topsoil by preferentially promoting plant-derived C accumulation.展开更多

文摘Rheumatoid arthritis(RA)is a refractory autoimmune disease with limited treatment options.Plantderived exosomes-like nanovesicles(PDENs)have emerged as a novel nanomedical approach,with the inherent bioactive compounds from their source plants.The roots of Morinda officinalis How.(MO),a Chinese herb,exhibit notable anti-inflammatory activities and hold promising therapeutic value.We engineered a joint-targe ting delivery system(termed MOE@EM)by masking MO-derived exosomes-like nanovesicles(MOE)with erythrocyte membrane(EM).This biomimetic strategy,using EM camouflage,is intended to improve the in vivo fate of MOE.We investigated the antioxidative and anti-inflammatory activities,immunogenicity,drug accumulation in the joint,and therapeutic efficacy to ascertain its suitability for RA therapy.UV irradiation significantly increased the activities of catalase and peroxidase of MOE,and enhanced the anti-inflammatory effects via the Wnt/β-catenin pathway.Furthermore,MOE@EM markedly attenuated dendritic cell activation.MOE@EM exhibited joint-specific delivery,with substantial reduction in paw swelling,and favorable modulation of immune microenvironment.
文摘Pharmaceutical-Food Homologous Plant-Derived Carbon Dots (P-CDs) have emerged as revolutionary nanomaterials in environmental pollutant management, demonstrating transformative potential for green chemistry and sustainable material applications. These carbon dots establish an innovative technical framework by integrating dual "detection-remediation" functionalities through eco-friendly synthesis and high-value conversion of medicinal-edible plants and agroforestry waste. Their core advantages originate from structural templating effects induced by natural functional groups (polyphenols, amino acids) in plant precursors combined with heteroatom self-doping, which synergistically optimizes optical properties. This combination achieves quantum yields ranging from 3.06% to 84.9% and detection sensitivities spanning nanomolar to micromolar concentrations. In pollutant detection applications, P-CDs enable ultrasensitive identification of heavy metals (Hg^(2+) , Cu^(2+) , Fe^(3+) ) and organic contaminants (pesticides, antibiotics) through multi-mechanistic interactions including static quenching (SQ), dynamic quenching (DQ), and F rster resonance energy transfer (FRET). However, technological translation faces critical challenges including quantum yield heterogeneity (>40-fold variation), matrix interference in complex environmental samples (signal drift exceeding 12%), and scalability-related process inconsistencies. Future research priorities should focus on three key areas: standardization of synthesis protocols, development of surface passivation strategies ( e.g. , SiO_(2) encapsulation), and optimization of heterojunction designs to enhance interference resistance. The integration of in situ characterization techniques (particularly X-ray absorption spectroscopy) with machine learning-driven parameter optimization could significantly refine detection-remediation synergies. Concurrently, establishing a comprehensive lifecycle assessment framework becomes imperative for evaluating environmental impacts and scalability potential. This technology pioneers a sustainable paradigm for pollution control by bridging the gap between nanomaterial innovation and industrial deployment, thereby accelerating progress toward global ecological security objectives.

文摘Nanotechnologies have been successfully applied to the treatment of various diseases.Plant-derived exosome-like nanoparticles (PENs) are expected to become effective therapeutic modalities for treating disease or in drug-delivery. PENs are minimally cytotoxic to healthy tissues, with which they show excellent biocompatibility, and are biased towards tumors by targeting specific tissues through special endocytosis mechanisms. Thus, the use of these PENs may expand the scope of drug therapies while reducing the off-target effects.In this review, we summarize the fundamental features and bioactivities of PENs extracted from the grape, grapefruit, ginger, lemon, and broccoli and discuss the applications of these particles as therapeutics and nanocarriers.

文摘MicroRNAs(miRNAs)are small noncoding RNA molecules ubiquitously distributed across diverse organisms,serving as pivotal regulators of genetic expression.Notably,plant-derived miRNAs have been demonstrated to have unique bioactivity and certain stability in mammalian systems,thereby facilitating their capacity for cross-kingdom modulation of gene expression.While there is substantial evidence supporting the regulation of mammalian cells by plant-derived miRNAs,several questions remain unanswered.Specifically,a comprehensive investigation of the mechanisms underlying the stability and transport of plant miRNAs and their cross-kingdom regulation of gene expression in mammals remains to be done.In this review,we summarized the origin,processing,and functional mechanisms of plant miRNAs in mammalian tissues and circulation,emphasizing their greater resistance to mammalian digestion and circulation systems compared to animal miRNAs.Additionally,we introduce four well-known plant miRNAs that have been extensively studied for their functions and mechanisms in mammalian systems.By delving into these aspects,we aim to offer a fundamental understanding of this intriguing field and shed light on the complex interactions between plant miRNAs and mammalian biology.

文摘Plant-derived extracellular vesicles(PEVs)have been regarded as a superior source for nanomedicine and drug delivery systems.Nevertheless,their clinical translation is hindered by the lack of clarity and even contradiction in their biomedical applications.Herein,we conducted a comprehensive compositional analysis of four commonly used PEVs to fully understand their functional lipid contents and assess their potential therapeutic applications.The lipidomic analysis revealed the presence of cytotoxic gingerols and shogaols in ginger-derived EVs(GEVs).Subsequent in vitro and in vivo investigations substantiated the remarkable tumor cell inhibitory and tumor growth suppression efficacy of GEVs.The transcriptomic analysis indicated that GEVs regulate the cell cycle and p53 signaling pathways,thereby inducing cancer cell apoptosis.The supplementary proteomic analysis suggested the potential protein markers in PEV research.These findings highlight the value of multi-omics analyses in elucidating the potential therapeutic effects of PEVs and in advancing the development of PEV-based therapies.

文摘Plant-derived nanovesicles(PDNVs),including plant extracellular vesicles(EVs)and plant exosome-like nanovesicles(ELNs),are natural nano-sized membranous vesicles containing bioactive molecules.PDNVs consist of a bilayer of lipids that can effectively encapsulate hydrophilic and lipophilic drugs,improving drug stability and solubility as well as providing increased bioavailability,reduced systemic toxicity,and enhanced target accumulation.Bioengineering strategies can also be exploited to modify the PDNVs to achieve precise targeting,controlled drug release,and massive production.Meanwhile,they are capable of crossing the blood-brain barrier(BBB)to transport the cargo to the lesion sites without harboring human pathogens,making them excellent therapeutic agents and drug delivery nanoplatform candidates for brain diseases.Herein,this article provides an initial exposition on the fundamental characteristics of PDNVs,including biogenesis,uptake process,isolation,purification,characterization methods,and source.Additionally,it sheds light on the investigation of PDNVs’utilization in brain diseases while also presenting novel perspectives on the obstacles and clinical advancements associated with PDNVs.

文摘Background and Objectives:Alzheimer’s disease(AD)is the most prevalent form of dementia in older individuals.Ferroptosis,a programmed cell death characterized by iron-dependent membrane lipid peroxidation is implicated in AD pathology.Increasing evidences have shown that plant-derived dietary antioxidants exhibit their anti-ferroptosis activity.However,the anti-AD mechanism of plant-derived dietary antioxidants remains elusive.Therefore,this review aims to explore the anti-AD effects of plant-derived dietary antioxidants via ferroptosis regulation.Methods and Study Design:This review examines the available published data from all peerreviewed original research articles on following topics:ferroptosis mechanisms,the role of ferroptosis in AD,the preclinical or clinical studies of plant-derived dietary antioxidants in cell,animal models of AD or patients with AD.Results:Ferroptosis is involved in AD pathology.Importantly,we clarify why docosahexaenoic acid(DHA)-rich brain phospholipids are extremely susceptible to lipid peroxidation.In addition,plant-derived dietary antioxidants such as vitamin E(VE),resveratrol,epigallocatechin-3-gallate(EGCG),curcumin,quercetin,baicalein and alpha-lipoic acid(ALA)show the anti-AD effects in preclinical AD models and prevent decline of cognition in healthy elderly population.Clinical studies show that ALA prevents decline of cognition of AD patients although most plant-derived dietary antioxidants exhibit conflicting results.Conclusions:It suggests that a plant-based diet may lead to potential health benefits in preventing cognitive decline in healthy elderly population.In regard to ALA,further clinical studies are highly recommended to evaluate its therapeutic potential that could optimize its dietary intake for preventing and alleviating decline of cognition of patients with AD.

文摘Saline–alkali land is an important cultivated land reserve resource for tackling global climate change and ensuring food security, partly because it can store large amounts of carbon(C). However, it is unclear how saline–alkali land reclamation(converting saline–alkali land into cultivated land) affects soil C storage.We collected 189 adjacent pairs of salt-affected and cultivated soil samples(0–30 cm deep) from the Songnen Plain, eastern coastal area, Hetao Plain, and northwestern arid area in China. Various soil properties, the soil inorganic C(SIC), organic C(SOC), particulate organic C(POC), and mineral-associated organic C(MAOC) densities, and plant-and microbial-derived C accumulation were determined.Saline–alkali land reclamation inconsistently affected the SIC density but significantly(P < 0.001)increased the SOC density. The SOC, POC, and MAOC densities were predicted well by the integrative soil amelioration index. Saline–alkali land reclamation significantly increased plant-derived C accumulation and the plant-derived C to microbial-derived C ratios in all saline–alkali areas, and less microbial transformation of plant-derived C(i.e., less lignin degradation or oxidation) occurred in cultivated soils than salt-affected soils. The results indicated that saline–alkali land reclamation leads to plant-derived C becoming the dominant contributor of SOC storage. POC storage and MAOC storage were strongly linked to plant-and microbial-derived C accumulation, respectively, caused by saline–alkali land reclamation.Our findings suggest that saline–alkali land reclamation increases C storage in topsoil by preferentially promoting plant-derived C accumulation.

文摘Extracellular vesicles(EVs)are phospholipid bilayer vesicles actively secreted by cells,that contain a variety of functional nucleic acids,proteins,and lipids,and are important mediums of intercellular communication.Based on their natural properties,EVs can not only retain the pharmacological effects of their source cells but also serve as natural delivery carriers.Among them,plant-derived nanovesicles(PNVs)are characterized as natural disease therapeutics with many advantages such as simplicity,safety,eco-friendliness,low cost,and low toxicity due to their abundant resources,large yield,and low risk of immunogenicity in vivo.This review systematically introduces the biogenesis,isolation methods,physical characterization,and components of PNVs,and describes their administration and cellular uptake as therapeutic agents.We highlight the therapeutic potential of PNVs as therapeutic agents and drug delivery carriers,including anti-inflammatory,anticancer,wound healing,regeneration,and antiaging properties as well as their potential use in the treatment of liver disease and COVID-19.Finally,the toxicity and immunogenicity,the current clinical application,and the possible challenges in the future development of PNVs were analyzed.We expect the functions of PNVs to be further explored to promote clinical translation,thereby facilitating the development of a new framework for the treatment of human diseases.

文摘Oxidative stress is a potentially critical factor that affects productive performance in gestating and lactating sows.Polyphenols are a large class of plant secondary metabolites that possess robust antioxidant capacity.All polyphenols are structurally characterized by aromatic rings with multiple hydrogen hydroxyl groups;those make polyphenols perfect hydrogen atoms and electron donors to neutralize free radicals and other reactive oxygen species.In the past decade,increasing attention has been paid to polyphenols as functional feed additives for sows.Polyphenols have been found to alleviate inflammation and oxidative stress in sows,boost their reproductivity,and promote offspring growth and development.In this review,we provided a systematical summary of the latest research advances in plant-derived polyphenols in sow nutrition,and mainly focused on the effects of polyphenols on the(1)antioxidant and immune functions of sows,(2)placental functions and the growth and development of fetal piglets,(3)mammary gland functions and the growth and development of suckling piglets,and(4)the long-term growth and development of progeny pigs.The output of this review provides an important foundation,from more than 8,000 identified plant phenols,to screen potential polyphenols(or polyphenol-enriched plants)as functional feed additives suitable for gestating and lactating sows.
