Broiler production has frequently faced economic losses due to infectious diseases caused by pathogenic microorganisms. These problems are commonly resolved using antibiotics, but doing so could lead to antibiotic resistance and impair food safety. This study evaluated the effects of a tamarind (Tamarindus indica L.) shell powder (TSP) supplementation on the growth performance and overall health status in broiler chickens. A total of 375 one-day-old male Ross 308 broilers were randomly assigned to five dietary treatment groups in a completely randomized design. Broilers received either a basal diet; antibiotic-supplemented diet; or diet supplemented with TSP at 1 × MIC, 16 × MIC, or 32 × MIC daily for 42 days. The results showed that treatment 4 (TSP 16 × MIC—64 mg per bird) had the best growth performance in broilers. Intestinal permeability measurements assessed using 4 kDa fluorescein isothiocyanate-conjugated dextran (FITC–dextran) showed that broilers fed the treatment 5 (TSP 32 × MIC—128 mg per bird) diet had significantly lower FITC–dextran concentrations in all intestinal segments (p < 0.05) and were determined to have higher serum FITC–dextran than the control group. The hematological parameters can significantly reduce serum cholesterol and triglycerides. Finally, the application of tamarind shell powder promoted probiotic proliferation within the broilers’ gastrointestinal tract and mitigated Enterobacteriaceae infections, demonstrating comparable efficacy to the antibiotic-treated control group. This research suggests that tamarind shell powder supplementation, especially at a medium dosage (treatment 4), may beneficially influence gut morphology, modulate the gut microbiota, and enhance intestinal health in broiler chickens.

This conceptual integrative review and theoretical proposal investigates how the functional architecture of Sternberg’s Triarchic Theory of Intelligence is reconfigured when the framework is translocated from low-risk academic settings, in which analytical intelligence predominates, to high-stakes professional environments characterised by extreme cognitive load, temporal compression, irreversible consequences, and multicultural team dynamics. To construct a mechanistic account of this translocation, we integrate the triarchic framework with three complementary cognitive–ecological traditions—Cognitive Load Theory, the three-level model of Situational Awareness, and the distributed-cognition tradition—and we use the maritime industry as a paradigmatic case where communication failures are directly implicated in catastrophic outcomes. On this basis we propose a Context-Dependent Reweighting Model of Successful Intelligence which maps how, under high-stakes conditions, practical intelligence shifts from a supporting role to a central, integrative function that operates in part through distributed cognitive systems, while creative intelligence assumes elevated weight for adaptive problem-solving when standardised procedures fail. We treat this reweighting as a theoretical proposition supported by convergent but heterogeneous secondary evidence, and we frame the cross-domain extension to aviation, emergency medicine, military operations, and other safety-critical sectors as theoretically plausible parallels and hypotheses for future empirical testing rather than as established empirical claims. The review concludes by articulating implications for intelligence research, proposing a pedagogical framework operationalised through a Triarchic Maritime ESP curriculum, and explicitly delimiting the boundary conditions and limitations of the present contribution.

Leonurine, a bioactive alkaloid from Leonurus japonicus, has attracted considerable pharmacological interest, yet its in vivo disposition remains insufficiently defined. In the present study, the pharmacokinetics, excretion, and metabolic profile of leonurine were systematically investigated in rats after intravenous (IV), oral (PO), and intraperitoneal (IP) administration. A validated LC–MS/MS method was used to quantify leonurine in plasma, urine, and feces, and high-resolution MS was applied for metabolite profiling. Following IV administration, leonurine exhibited rapid systemic disposition, with a half-life of 2.48 h and a clearance of 152 mL/min/kg. Oral exposure was negligible, with an absolute bioavailability of 0.14%, whereas IP administration produced markedly higher systemic exposure (66.6%). Recovery of unchanged leonurine in urine and feces remained low across all dosing routes, with total excretory recovery below 6% of doses. The results indicated that metabolic conversion, rather than parent drug excretion, was the dominant elimination pathway. A total of 30 leonurine-related components were characterized in vivo, including 24 previously unreported metabolites. The metabolic profile was dominated by phase II conjugation, comprising 12 glucuronidated and 12 sulfated metabolites, together with hydrolysis, methylation/demethylation, and other transformation products. Notably, ester bond cleavage was identified as one of the major primary biotransformation routes, and several glucuronide and sulfate conjugates were also formed on hydrolysis-derived fragments. These findings provide a more comprehensive view of leonurine disposition in rats and offer a mechanistic basis for its rapid clearance and limited systemic availability after oral administration.

Bidens pilosa L. (Asteraceae), a globally invasive weed native to the Americas, is widely distributed across tropical and subtropical regions and is listed as invasive alien species in many countries. Despite its ecological hazards, it possesses a long history of traditional use and substantial resource potential that remains incompletely synthesized. This review systematically compiles ethnobotanical records from 15 countries, documenting 60 traditional medicinal indications across 14 disease categories spanning Latin America, Africa, Asia, and Oceania. A structured cross-referencing analysis reveals that 26 (43.33%) of these traditional applications are supported by 17 verified pharmacological mechanisms, mediated by 19 classes of bioactive compounds, principally flavonoids, polyacetylenes, and phenolic acids. Among these, anti-inflammatory, antidiabetic, antitumor, and antimicrobial activities are the most consistently validated. Moreover, this review synthesizes four non-medicinal utilization pathways: dietary use, animal feed, environmental remediation, and industrial raw materials. The resource value of B. pilosa has been independently recognized in the native and introduced ranges alike. Building on this evidence, we propose a “control-through-utilization” framework. To mitigate potential risks in practical exploitation, three targeted strategies are put forward, including timely harvesting, on-site processing and heavy metal safety inspection. This review supports the sustainable management of B. pilosa and offers methodological references for resource exploitation and control of other invasive plants. Full article

Physalis alkekengi L. var. franchetii (Mast.) Makino (P. alkekengi) is a well-known traditional Chinese medicine (TCM) with dual edible and medicinal values. Its polysaccharides (PAPs), as core bioactive constituents, have drawn growing research interest amid advances in natural product studies, whereas systematic summaries of existing evidence remain insufficient. This paper collects and analyzes recent progress regarding PAPs extraction, purification, structural characterization, biological activities and targeted applications in diverse food matrices. Current bottlenecks restricting PAPs development are also discussed from multiple research perspectives. Major research outcomes reveal that diverse extraction and purification techniques determine PAPs yield and structural heterogeneity, and characterized structural features are closely associated with their antioxidant, anti-inflammatory, immunomodulatory and other bioactivities. Inadequate mechanistic exploration, incomplete toxicological evaluation and immature industrial extraction systems are critical obstacles limiting further translational application of PAPs. Targeted future research directions are accordingly proposed to address these gaps. This work provides a comprehensive reference and theoretical support for deeper investigation, development and utilization of PAPs as functional food ingredients or herbal bioactive agents.

The NAM, ATAF, and CUC (NAC) transcription factors represent a major class of plant-specific transcription factors that regulate plant growth, development, and responses to various biotic and abiotic stresses. Despite their importance, limited information exists about this gene family in wolfberry (Lycium barbarum), a valuable traditional Chinese medicinal plant widely cultivated in northwest China. In this study, 107 LbaNAC genes were identified from the wolfberry genome and found to be unevenly distributed across 12 chromosomes. These LbaNAC genes were clustered into 18 subfamilies, with motif composition and gene structure showing high consistency with their phylogenetic relationships. A total of 192 orthologous gene pairs were identified between wolfberry and tomato, potato, Arabidopsis thaliana, and rice, respectively. Gene duplication analysis revealed that dispersed duplication was a major driver in the expansion of the LbaNAC gene family, while the analysis of the nonsynonymous (Ka) to synonymous (Ks) substitution rates confirmed that purifying selection has been the predominant evolutionary force acting on these genes. Cis-acting element analysis showed that their promoters harbor elements associated with growth, metabolism, and various stress responses. Furthermore, correlation analysis demonstrated that the expression profiles of LbaNAC001, 027, 043, 051, 053, and 080 were significantly and positively correlated with the dynamic changes in glucose, fructose, and sucrose contents in wolfberry fruits. Furthermore, quantitative real-time PCR validation of the selected LbaNAC genes confirmed that their expression patterns were consistent with the transcriptome data. Subcellular localization and transcriptional activation analyses revealed that LbaNAC027 is a nucleus-localized transcriptional activator. This study identifies potential LbaNACs involved in wolfberry fruit sugar metabolism, providing a theoretical foundation for elucidating their regulatory mechanisms. Full article

Psoriasis is a refractory skin disease that is often accompanied by systemic comorbidities. While the efficacy of biologics in treating psoriasis is well-established, these treatments are also associated with frequent adverse reactions. Consequently, there is an urgent need to develop new treatment strategies for psoriasis. Pomegranate peel, which is widely used in skincare and protection, has not been fully studied for its therapeutic potential in psoriasis. This article investigates the therapeutic effectiveness of pomegranate peel ethanol extract (PEE) on psoriasis. A total of 2872 compounds were identified in PEE. The topical application of PEE alleviated primary psoriasis-like skin lesions and reduced lesion recurrence in mice. PEE simultaneously activates AhR and inhibits the Th17/IL-17 axis and neuronal-related pathways, which may serve as a mechanism for PEE in the treatment of psoriasis. In conclusion, our study establishes that PEE may serve as a novel therapeutic agent for psoriasis, with a unique mechanism of action that simultaneously activates AhR and suppresses neuronal-related pathways.

Dendrobium officinale has attracted increasing attention as a functional food because of its diverse biological activities; however, the photoprotective potential of its protein-derived peptides remains poorly understood. In this study, D. officinale protein hydrolysates were fractionated by ultrafiltration according to molecular weight, and their protective effects against ultraviolet B (UVB)-induced photoaging were systematically evaluated in HaCaT keratinocytes. Among the tested fractions, low-molecular-weight peptide fractions exhibited relatively stronger antioxidant activity and effectively reduced intracellular reactive oxygen species (ROS) accumulation in UVB-irradiated cells. In addition, the peptide fractions alleviated UVB-induced inflammatory responses and decreased matrix metalloproteinase (MMP) expression, which was associated with modulation of mitogen-activated protein kinase (MAPK) and nuclear factor kappa B (NF-κB) signaling pathways. Higher-molecular-weight fractions showed relatively stronger effects on maintaining skin barrier-related functions and were associated with regulation of transforming growth factor-β/Smad (TGF-β/Smad) signaling and collagen-related protein expression. Overall, these findings demonstrate functional differences among Dendrobium officinale peptide fractions and suggest their potential application as natural photoprotective ingredients in functional foods and cosmeceutical products.

Recent studies indicate that ferroptosis shows unique advantages in oncotherapy, particularly in reversing multidrug resistance (MDR). Despite current therapeutic advancements, the treatment of high-incidence malignancies with dismal prognoses continues to face challenges, including limited clinical efficacy, significant side effects, and drug resistance. In recent years, Chinese herbal medicine (CHM) has gained increasing attention in anti-tumor therapy. CHM bioactive components are highly effective in inducing tumor cell ferroptosis, inhibiting tumor proliferation and migration, and reversing drug resistance. Additionally, some components can protect normal cells and improve the tumor microenvironment. This review systematically summarizes the regulatory roles of various CHM bioactive components in ferroptosis across common human cancers. We further analyze the underlying molecular mechanisms, focusing on the modulation of key regulatory targets (e.g., GPX4, SLC7A11, and Nrf2) and critical signaling cascades (e.g., PI3K/AKT/mTOR and p53). Furthermore, the differential effects of bioactive compounds from CHM on common tumors were evaluated, alongside their potential in combination therapy. This review provides a theoretical foundation for the development of novel anticancer drugs targeting ferroptosis regulation and offers new perspectives for the clinical application of CHM in oncology.

Osteoarthritis (OA) and major depressive disorder (MDD) share inflammatory and oxidative stress pathways, but the role of programmed cell death (PCD) in their comorbidity remains unclear. This study used independent OA synovial and MDD peripheral blood transcriptomic datasets—not a unified comorbid discovery cohort—to identify candidate PCD-related molecular signatures commonly dysregulated in both conditions. Transcriptomic data from OA synovium and MDD brain tissues were obtained from GEO (six training [three OA synovial and three MDD peripheral-blood], seven validation, and two single-cell RNA-seq datasets). Differentially expressed genes (DEGs) were identified, and PCD-related DEGs were screened. Machine learning (LASSO, SVM-RFE, Random Forest) was used to identify hub PCD-DEGs from the OA training set. WGCNA identified MDD-associated modules for comorbidity-gene selection. Functional enrichment, immune infiltration, scRNA-seq localization, and clinical validation (qRT-PCR/WB) were performed. From the OA cohort, four hub PCD-DEGs (CDKN1A, CX3CR1, INHBB, RHOB) showed moderate diagnostic value for OA (nomogram AUC = 0.82). Eight candidate genes (VAMP8, PDK4, P2RX4, ITM2C, IL10RA, HSP90AA1, CTSO, CRIP1) were commonly dysregulated across both OA and MDD datasets. Immune infiltration revealed upregulated B memory cells, plasma cells, Tregs, and neutrophils in OA, and neutrophils in MDD. scRNA-seq localized CDKN1A/RHOB to OA synovial cells and HSP90AA1/ITM2C to MDD neurons. Enrichment analyses highlighted TNF signaling, apoptosis, and stress responses in both diseases. An independent OA–MDD clinical cohort confirmed differential expression of CDKN1A, RHOB, ITM2C, and HSP90AA1. This study identifies four PCD-related hub genes associated with OA and eight candidate comorbidity genes showing common dysregulation across OA and MDD datasets and in an independent clinical cohort. These findings generate hypotheses about shared inflammatory pathways linking OA and MDD. As these associations derive from independent disease-specific cohorts rather than a true comorbid discovery cohort, they represent candidate signatures requiring functional validation rather than established mechanisms.

Nanotheranostics integrate theranostic functions onto a single nanoscale platform, and have become a new approach in precision medicine. Nanotheranostics rely on probes. However, traditional fluorescent probes often exhibit aggregation-caused quenching (ACQ) when loaded at high concentrations onto nanocarriers, severely limiting their imaging performance. Aggregation-induced emission agents (AIEgens) offer a solution to this long-standing problem through their ability to enhance fluorescence during aggregation. This mini-review systematically outlines nanotheranostic systems based on aggregation-induced emission (AIE). We first introduce the basic mechanism of AIE (the limitation of molecular internal motion) and its advantages over traditional fluorescent probes. Then, we discuss the design strategies of AIE nanoprobes according to the types of nanocarriers (including liposomes, polymer nanoparticles, and self-assembling systems). Additionally, we emphasize the disease-specific AIE nanotheranostic designs tailored for pathological microenvironments such as tumors, neurodegenerative diseases, and inflammatory diseases. Finally, we conduct an in-depth analysis of the current challenges hindering clinical translation, and propose future AIE nanotheranostic technologies applicable to clinical practice and the direction for personalized medicine.

Skin health depends on the coordinated maintenance of barrier integrity, immune homeostasis, redox balance, microbial ecology, and systemic metabolic status. Among dietary constituents, polysaccharides have attracted increasing attention because they represent a structurally heterogeneous class of complex carbohydrates whose biological behavior is shaped by molecular weight, monosaccharide composition, glycosidic linkage patterns, branching, higher-order conformation, and physicochemical properties. However, many current skin-related studies remain primarily phenomenon-driven, with insufficient attention to how specific structural features influence biological function and dermatologic relevance. From a structure–function perspective, key structural features of dietary polysaccharides may influence several skin-relevant biological processes, including microbiota-associated signaling, immune regulation, barrier homeostasis, oxidative balance, and extracellular matrix protection. The relevance of these structure-linked functions differs across dermatologic contexts: it appears most direct in photoaging, more conditional in atopic dermatitis, and relatively indirect in psoriasis, whereas wound-repair-related settings are less closely aligned with strict dietary relevance. Current evidence therefore supports structure–function associations more strongly than direct associations between specific structural features and dermatologic outcomes. Dietary polysaccharides are not functionally interchangeable in skin-related contexts, and their skin-related effects depend on structural background, disease setting, and mode of application. Where non-dietary evidence is discussed, it serves primarily as mechanistic or translational contextualization rather than as a basis for nutritional recommendation. Clarifying these relationships may support future mechanistic research and facilitate more rational nutritional applications of dietary polysaccharides in skin health. Full article

Background/Objectives: Peripheral-blood transcriptomic profiling can capture molecular heterogeneity in systemic lupus erythematosus (SLE), but discovery-stage signatures often show limited transportability across cohorts and validation layers. This study aimed to establish a staged whole-blood transcriptomic framework and to derive a compact, biologically interpretable activity score. Methods: Public whole-blood bulk transcriptome cohorts were organised into discovery, public validation, and single-cell reference layers. Local orthogonal validation included a peripheral blood mononuclear cell (PBMC) reverse transcription quantitative PCR (RT-qPCR)/flow-cytometric cohort and an expanded whole-blood RT-qPCR validation set. Discovery-stage BloodGen3 profiling included 233 samples, comprising 170 SLE and 63 healthy controls, and endotype discovery was restricted to SLE samples. Candidate genes were compressed into two 6-gene panels, with final selection adjudicated through staged public validation. Results: Two working whole-blood endotypes were identified, characterised by lymphoid versus myeloid/neutrophil-inflammatory polarisation. Although pre6-any showed a marginal discovery-stage advantage, the predefined integrated public-stage adjudication favoured pre6-balanced (MMP9, MYL9, HAL, CTLA4, CD40LG, VPREB3), which was locked as the final panel. In the PBMC cohort, the locked score discriminated SLE from healthy controls (AUC 0.838) and high from low/moderate disease activity (AUC 0.719), with associations with SLEDAI, complement C3/C4, and monocyte subpopulations. In the expanded whole-blood validation set, the score showed SLE-versus-HC discrimination (AUC 0.888, 95% CI 0.821–0.954), high versus low/moderate activity discrimination (AUC 0.918, 95% CI 0.831–0.980), and association with SLEDAI (ρ = 0.819, p = 1.25 × 10⁻¹⁵). Conclusions: This staged framework yielded a compact myeloid–lymphoid activity score supported across public and local validation layers. The score should be interpreted as a research-grade relative activity score and warrants prospective evaluation in SLE. Full article

Crop residue management strongly influences soil microbial communities, yet the mechanisms by which it regulates microbial co-occurrence network assembly across soil profiles remain poorly understood. Here, we investigated the effects of three straw management practices—no straw return (CK), straw burning (BS), and deep plowing with straw incorporation (DPS)—on soil physicochemical properties, microbial diversity, and co-occurrence network structure across multiple soil depths in a Mollisol of Northeast China. By integrating high-throughput sequencing, network analysis, and structural equation modeling (SEM), we explored the correlative relationships associated with microbial network assembly. DPS significantly correlates with higher soil organic carbon content, nutrient availability, and moisture content, particularly in subsoil layers. Under DPS, we obtained more complex and robust microbial networks characterized by higher connectivity and clustering. In contrast, under BS, we found reduced network complexity and stability. SEM may suggest the presence of distinct assembly mechanisms between microbial groups: bacterial network structure models responded to soil physicochemical properties, suggesting strong environmental filtering, whereas shifts in fungal network structures correlate with alpha diversity, highlighting the importance of biotic regulation. Notably, under the evaluated conditions, beta diversity was positively associated with network structural attributes across both groups, indicating potential links between community compositional variation and microbial co-occurrence patterns. These findings suggest that straw incorporation may be associated with shifts in microbial co-occurrence network attributes under the evaluated field conditions. However, the observed relationships are primarily correlative and based on statistical modeling approaches. The underlying ecological mechanisms linking soil properties, microbial diversity, and network structure require further validation through controlled biochemical, physiological, and experimental studies. This study provides additional ecological insights into soil microbial responses to residue management and highlights the potential role of residue management in shaping microbial network stability under the evaluated field conditions.

Cyathula officinalis Kuan, a medicinal plant used in traditional medicine, remains underexplored as a source of structurally defined wound-repair polysaccharides. In this study, a water-soluble polysaccharide fraction, CoPS, was isolated from C. officinalis roots and structurally characterized using methylation analysis and 1D/2D NMR spectroscopy. Purified CoPS had a total carbohydrate content of 94.8%, a weight-average molecular weight (M_w) of 7.491 kDa, and a narrow dispersity (M_w/M_n = 1.04). Monosaccharide composition analysis showed that CoPS was mainly composed of fructose and glucose at a molar ratio of 95.60:4.40. Structural analyses identified CoPS as a branched levan-type fructan with a β-(2→6)-linked fructofuranosyl backbone and β-(2→1)-linked branching motifs. CoPS was incorporated into a Carbomer/alginate topical formulation, termed CoPS-CPG, and evaluated in vitro and in vivo. CoPS-CPG showed good cytocompatibility and promoted HaCaT keratinocyte migration, reducing the residual scratch area to 48.10% at 12 h compared with 70.13% in the control group and 65.18% in the vehicle (Blank-CPG) group. In a murine full-thickness excisional wound model, CoPS-CPG reduced the residual wound area to 8.70 ± 1.20% on day 14, compared with 24.83 ± 1.51% in the control group and 14.20 ± 0.72% in the vehicle group. Histological and immunological analyses further indicated improved tissue reconstruction, a reduced inflammatory burden, enhanced CD206-associated macrophage signals, increased CD31-associated vascular structures, improved α-SMA-associated perivascular coverage, and lower late-stage HIF-1α expression. These findings identify CoPS as a structurally defined plant-derived levan-type fructan that supports cutaneous wound repair. Full article
