Green manures are widely used to enhance soil health and suppress plant-parasitic nematodes, and their effects on the broader soil food web have been studied. Beyond direct suppression, the role of green manures in supporting and sustaining soil food webs has attracted increasing attention. In this study, we evaluated the use of DNA sequencing to identify various nematode genera and their microbial associates in a field trial using oat (Avena sativa) and hairy vetch (Vicia villosa) as green manures. Nematode index analysis revealed that the oat treatment promoted a structured nematode community. Furthermore, the nematode community structure observed in the oat treatment was linked to specific bacterial and fungal genera. Several beneficial fungi were identified, indicating that oats, used as a green manure, actively enhanced the microbiome. Our results showed that enriching the micro-food web through organic fertilizers can help in the detection of beneficial microorganisms, with the nematode index serving as a potential indicator.

The anterior pituitary gland secretes the peptide hormone prolactin, which is important for lactation, reproductive health, and metabolic regulation. Its secretion is primarily regulated by dopamine and also its elevated level is known as hyperprolactinemia. The aim of this study was to assess serum prolactin level in T2DM patients at the University of Gondar comprehensive specialized hospital. A comparative cross-sectional study was conducted from June 27 to August 20, 2024 involving 330 study participants selected using systematic random sampling. Of these, 165 were male patients with T2DM and 165 were apparently healthy controls. Sociodemographic, behavioral, and clinical data were measured by structured questionnaires. Hormonal parameters, Fasting blood sugar and lipid profiles were measured by chemiluminescent immunoassay and spectrophotometric principles respectively. Data were analyzed using SPSS version 25. Descriptive statistics, independent t-tests, and binary logistic regression were performed with significance set at p < 0.05. The prevalence of hyperprolactinemia was 9.1% in T2DM patients and 6.1% in the control group. A statistically significant difference in mean serum prolactin level was observed between T2DM and control group (7.79 ± 2.9 vs. 6.81 ± 3.1, p-value = 0.004) respectively. Hyperprolactinemia was more likely to occur in study individuals with high dietary diversity (AOR = 3.213, 95% CI: 1.253-8.239, P-value = 0.015). The incidence of hyperprolactinemia increases by 1.009 (95% CI: 1.001-1.018; P-value = 0.035) for every unit rise in FBS (1 mg/dl). In conclusion, the mean serum prolactin level was significantly higher among T2DM patients compared to healthy control groups. In addition, the prevalence of hyperprolactinemia was higher in T2DM patients than the control groups. Dietary diversity and elevated FBS were a significant predictors of hyperprolactinemia. So, the healthcare providers should consider routine screening of serum prolactin level in patients diagnosed with T2DM.

The present study aimed to determine the phytochemical characterization, anticancer and antioxidant activities of essential oils (EOs) obtained from nine commonly used medicinal and aromatic plants (MAPs) including Cymbopogon citratus (DC) Stapf (Poaceae), Cistus creticus L. (Cistaceae), Foeniculum vulgare Mill. (Apiaceae), Laurus nobilis L. (Lauraceae), Myrtus communis L. (Myrtaceae), Pinus cembra L. (Pinaceae), Echinacea purpurea (L.) Moench, Helichrysum arenarium (L.) Moench, and Inula viscosa (L.) Aiton (Asteraceae) taxa from Türkiye. The chemical composition of the EOs was identified using gas chromatography-mass spectrometry (GC-MS), and their antioxidant activities were evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) free radical scavenging methods. In addition, the anticancer potential of the EOs were assessed using MTT assay against human cell lines, including hepatocellular carcinoma (HepG2), gastric carcinoma (NCI-N87), breast adenocarcinoma (MCF-7), and human prostate carcinoma (LNCaP clone FGC-Luc2) cancer cells, as well as non-cancerous human umbilical vein endothelial cells (HUVECs). The antioxidant activities of the EOs varied from 35.21 to 79.12%. Consistent with their antioxidant activities, the anticancer activities of the EOs of C. citratus, L. nobilis and, C. creticus exhibited significantly higher anticancer activities compared to the others. However, almost all EOs were found to inhibit cell viability and induce apoptosis in cancer cells. Among the tested concentrations, the highest anticancer activity was observed against against MCF-7 cells, followed by NCI-N87, LNCaP, and HepG2 cancer cells, with the IC50 values ranging from 15.10 ± 1.00 to 78.12 ± 0.32 µg/mL, respectively. The major components of the EOs distilled from studied MAPs were found as anethole, borneol, carvacrol, citral, α-pinene, eucalyptol and β-citral at different concentrations in the EOs. Overall, it can be clearly concluded that the EO samples distilled from studied MAPs contain valuable bioactive compounds and accordingly exhibit remarkable biological activities.

Wearable pressure sensors have become essential for monitoring human health and facilitating human–machine interaction. However, pressure sensors generate heat during operation, which may reduce their service life and lead to localized burns due to overheating. To address these issues, we employ metal–organic frameworks (MOFs) to dope pressure sensors and investigate their effects on device performance. Here, wearable pressure sensors based on MOF/thermoplastic polyurethane/reduced graphene oxide (MOF/TPU/GAFF) are developed for rapid heat dissipation. We selected four MOFs with high thermal conductivity (Zr–MOF, Mn–MOF, MOF‐5, and ZIF‐8) and mixed them into a TPU/GAFF fiber film. The enhanced thermal conductivity of the modified TPU/GAFF matrix contributes to improved heat dissipation performance in the devices. Among the tested materials, the doped ZIF‐8 composite film exhibits the most effective heat dissipation, with a heat exchange capacity 1.56 times higher than that of the undoped ZIF‐8 composite film. Furthermore, the incorporation of ZIF‐8 significantly enhances sensor sensitivity. The ZIF‐8‐based sensor demonstrates optimal performance, achieving a sensitivity of 0.27 kPa −1 within the pressure range of 0–50 kPa, representing a 595.2% improvement compared to the sensor without ZIF‐8. Overall, the sensor provides a wearable electronic platform with strong application potential in monitoring human health and speech recognition.

Inhaled opportunistic pathogens such as Pseudomonas aeruginosa actively modify gene expression to meet the challenges of a new environment. In the infected airway the bacteria must respond to the immunometabolite itaconate, which is abundantly produced by macrophages and has anti-inflammatory and anti-oxidant functions that protect the host from airway damage and causes toxicity to bacteria. As a dicarboxylate that targets cysteine residues, itaconate can modify both bacterial and host proteins often altering metabolic activity. We demonstrate that itaconate promotes a global metabolic response in P. aeruginosa by enhancing the activity of the major alternative transcription factor RpoN. Itaconate is actively transported into the bacteria, induces σ54 rpoN expression and covalently binds cysteine residues 218 and 275 on RpoN helping to neutralize its toxicity. The S-itaconated RpoN exhibits a gain of function driving increased glucose catabolism and enhanced utilization of the bioenergetically efficient Entner-Doudoroff pathway. Thus, the accumulation of itaconate in the infected airway promotes the adaptation of P. aeruginosa to the lung by optimizing its metabolic activity and ability to cause pneumonia.

This study evaluated the long-term metabolic effects of prenatal nutrition in Nellore bulls. Pregnant cows (n = 126) received mineral supplementation only (NP), protein-energy supplementation during the last trimester (PP), or supplementation throughout pregnancy (FP). At slaughter, longissimus (muscle and meat) and subcutaneous fat samples from the offspring were collected for transcriptomics and metabolomics analyses. Data were reduced using Weighted Gene Co-expression Network Analysis, followed by functional enrichment, and then integrated via Spearman's correlations and holistic pathway analysis. Distinct molecular patterns emerged across prenatal nutrition treatments, although all groups influenced energy metabolism and cellular processes. The NP group was strongly associated with protein and lipid metabolism, highlighted by PPAR and sphingolipid signaling pathways, and key hub components including CNOT4 and tryptophan. In contrast, PP and FP groups were more closely linked to immune function, stress resilience, with enrichment of NF-kB signaling, cortisol synthesis, and hub components including TIE1, YWHAZ, carnitine, and glutaconylcarnitine. Shared transcriptome-metabolome modules between groups displayed inverse correlations, suggesting potential antagonistic effects driven by maternal diet. Overall, these results indicate that prenatal nutrition shapes key metabolic processes in muscle, meat, and fat, offering insights to enhance meat quality and production through maternal feeding strategies.

Direct production of pressurized green hydrogen via photoelectrochemical water splitting reduces the need for mechanical compression and mitigates bubble-related losses. However, existing demonstrations have been limited to atmospheric pressure. Here, we bridge this gap by designing, constructing, and testing a high-pressure flow cell for photoelectrochemical water splitting using two configurations. In a back-illuminated BiVO4-based photoelectrochemical cell, increased pressure suppresses bubble evolution and alleviates photocurrent saturation under concentrated sunlight: at 10 suns, the photocurrent rises from 3× at 1 bar to ~7× at 5 bar. Direct operando imaging of the electrode surfaces confirms that this improvement comes primarily from suppressed bubble evolution. Conversely, a front-illuminated platinized triple-junction III-V-based photoelectrochemical cell shows limited pressure dependence up to 8 bar due to its dispersed catalyst and long carrier diffusion length. These findings highlight the differing response of photoelectrochemical devices to elevated pressure and demonstrate a viable pathway toward scalable, high-pressure solar-driven hydrogen production.

The electrochemical conversion of biomass-derived 5-hydroxymethylfurfural (HMF) represents a promising, economically viable, and environmentally sustainable approach for producing value-added chemicals using renewable energy and in situ hydrogen generated through water electrolysis. However, the electrochemical hydrogenation (ECH) of HMF remains challenging due to the inherently low catalytic activity and selectivity of the electrodes, compounded by competition with the kinetically favored hydrogen evolution reaction (HER) in aqueous electrolytes. In this work, we demonstrate that CuxNi100-x heteroatomic thin films, fabricated via direct current (DC) magnetron co-sputtering, achieve a more than one order of magnitude increase in the HMF to 2,5-Bis-hydroxymethylfuran (BHMF) conversion rate, with nearly 50% faradic efficiency (FE) for BHMF, when compared to pure Cu and Ni electrodes (~ 10% BHMF FE). Our results suggest that the synergistic interaction between Cu and Ni creates an optimal catalytic environment for both HMF and adsorbed hydrogen (Hads) species, thereby enhancing BHMF formation through the ECH pathway.

Our results suggest that the synergistic interaction between Cu and Ni creates an optimal catalytic environment for both HMF and adsorbed hydrogen (H<sub>ads</sub>) species, thereby enhancing BHMF formation through the ECH pathway.</p>","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145744469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under the impact of climate change, the Ming Great Wall of China is facing accelerated weathering on an unprecedented scale. Based on the principles of the soft capping approach, we propose to use the “natural capping” approach by applying native plants and soil medium that are adaptable to the in situ environments. Following field surveys of the Ming Great Wall in Shanxi Province, four scaled-down earthen walls were fabricated to support the growth of selected native plants on the top surfaces. Long-term monitoring revealed that the earthen walls covered by natural capping, especially native herbs with more biomass, could effectively influence thermal behaviour and moisture movement of the earthen walls, thus providing sustainable preservation effects in semi-arid regions. Compared with bare wall, natural capping reduced the number of freeze-thaw cycles at the top of the wall by 41.2 % in winter, decreased the average rate of temperature increase by 47.2 % in summer, and reduced the daily temperature difference and the temperature gradient between the range of 0 and 20 cm. Under the effects of rainfall, natural capping effectively stabilizes the moisture content in winter, decreases moisture fluctuation frequency by >61.9 % and delays the start time of moisture infiltration in the interior walls during summer. After one year of outdoor monitoring, the total loss of earth material was reduced significantly by 82.5 %. The findings of this work provide informed technical support for the long-term preservation of earthen heritage via the natural approach.

Introduction
The phyllosphere microorganisms colonizing plant surface harbor capacities to synthesize diverse specialized metabolites that mediate communication and interactions with environment and host. However, most known metabolites are derived from a few culturable microorganisms, and the genomic diversity and biosynthetic potential of the vast majority of bacteria associated with plants remain largely unexplored.
Objectives
Here, we aim to explore the genome architecture, biosynthetic ability, and host specific adaptability of grassland ecosystems, uncovering new perspectives on grassland phyllosphere microbial resources.
Methods
We employed ultra-deep metagenomic sequencing, functional analysis, host-associated characterization, and bioactivity assays to explore the phyllosphere microbiome across 221 grassland plant samples representing 45 families. This approach revealed host preference in biosynthetic gene clusters (BGCs) and validated the antimicrobial efficacy of phyllosphere-derived antimicrobial peptides (AMPs).
Results
Grassland plant phyllosphere microbiomes encode diverse BGCs. We identified 885,396 potential AMPs from over 68 million non-redundant gene sequences. Then, we reconstructed hundreds of near-complete genomes from phyllosphere metagenomes, and 32.61 % of reconstructed genomes were identified as unclassified genomes, primarily within Pseudomonadota, Actinomycetota, Bacillota and Bacteroidota phyla. Of the near-complete genomes, 91.97 % of the BGCs and 99.76 % of the identified AMPs were previously uncharacterized. Host phylogenetic analysis revealed functional divergence. Poaceae-associated Pseudomonas genomes contain an average of 28 BGCs, significantly higher than those in Asteraceae-associated genomes (mean = 14.76, P = 0.033). Similarly, Poaceae-associated Pantoea genomes carried an average of 9 BGCs, exhibiting significant enrichment compared to genomes from Asteraceae (mean = 7.13, P = 6.1e-05), Lamiaceae (mean = 7, P = 0.015), Ranunculaceae (mean = 8.22, P = 0.0053), and Rosaceae (mean = 7.75, P = 0.00069). ParaFit analyses further confirmed that host phylogeny significantly structures microbial functional repertoires, with intra–family hosts sharing more KEGG pathways than inter–family hosts. These results suggest that host evolutionary relationships are associated with metabolic specialization in phyllosphere microbiomes. All 13 AMPs synthesized via solid-phase peptide synthesis demonstrated antimicrobial activity, inhibiting the growth of at least one tested bacterial strain.
Conclusion
This study demonstrates the promise of grassland plant phyllosphere microbiome as a rich source for novel antimicrobial agents.
