Soil-dwelling predatory mites (Acari: Mesostigmata) are key components of decomposer-based soil food webs and contribute to the regulation of soil microarthropods, including agricultural pests. Despite their ecological and applied importance, the predatory mite fauna of Slovenia has remained poorly documented. This study provides the first systematic inventory of soil-dwelling mesostigmatid mites in Slovenia, based on standardized sampling conducted between July and October 2024 and between June and September 2025. Samples were collected from a range of organic substrates, including stable manure, compost, vermicompost, decomposing plant material and forest litter, and mites were extracted using a modified Berlese–Tullgren method. In total, 31 predatory mite taxa belonging to nine families were recorded, with all species except Macrocheles glaber being reported for the first time in Slovenia. Diversity analyses, based on species richness, Shannon index and minimum confirmed abundance, revealed clear differences in community structure among substrate types. Manure- and compost-based substrates showed the highest species richness and abundance, whereas forest litter supported lower diversity but more even communities. Several recorded genera include species with documented or potential relevance for the suppression of soil-dwelling pests such as Rhizoglyphus spp. These findings provide baseline data for future faunistic, ecological and applied research and improve our understanding of predatory mite communities in organically enriched agroecosystems.

Background: Vitamin B12 deficiency is a recognized but frequently under-integrated cause of global developmental delay (GDD) in infancy and early childhood. Early diagnosis is critical because neurological impairment may be partially or completely reversible with timely treatment. Objective: This narrative review aims to synthesize current evidence on the role of vitamin B12 deficiency in the diagnostic evaluation of GDD, with a focus on clinical phenotype, risk factors, biomarkers, treatment outcomes, and practical integration into contemporary diagnostic algorithms. Methods: A structured, non-systematic search of PubMed/MEDLINE, Embase, and Web of Science was performed to identify clinical studies, case series, reviews, and guideline documents addressing pediatric vitamin B12 deficiency and neurodevelopmental delay. Results: Vitamin B12 deficiency in early childhood is most commonly associated with maternal deficiency and exclusive breastfeeding without adequate supplementation. Evidence from recent clinical and observational studies indicates that vitamin B12 deficiency may present with nonspecific neurological symptoms, including developmental regression, hypotonia, and feeding difficulties. Incorporating vitamin B12 assessment—using serum vitamin B12, holotranscobalamin, methylmalonic acid, and homocysteine—into early diagnostic algorithms for GDD may facilitate timely identification of a treatable cause of neurodevelopmental impairment. The proposed diagnostic framework emphasizes early biochemical evaluation in infants with unexplained developmental delay, thereby supporting prompt treatment during a critical window of neurological reversibility. Conclusions: Targeted assessment of vitamin B12 status in children with GDD, together with evaluation of maternal status, represents a clinically relevant approach to identifying a potentially preventable and treatable cause of neurodevelopmental impairment. Integration of functional biomarkers into diagnostic pathways and the development of pediatric-specific reference standards are key priorities for future research and clinical practice. Full article

Excess post-exercise oxygen consumption (EPOC) reflects cardiorespiratory fitness, energy metabolism and the residual physiological effects of preceding exercise. We aimed to compare EPOC profiles of master swimmers across different age groups and performance levels. Fourteen male master swimmers performed a 200 m all-out front crawl and breath-by-breath gas exchange and their heart rates were recorded during exercise and for 5 min post-exercise. A single exponential regression model was fitted to the post-exercise oxygen uptake kinetics to determine the EPOC amplitude, time constant and time delay. The EPOC magnitude was calculated as the area under the oxygen uptake–time curve. Swimmers were grouped into younger vs. older and faster vs. slower clusters using the 50th percentile, and the associations between age, performance and physiological variables were examined. Older swimmers were slower and showed a lower peak oxygen uptake than their younger counterparts (213.9 ± 27.9 vs. 165.7 ± 24.9 s and 39.1 ± 4.8 vs. 50.2 ± 8.1 mL∙kg⁻¹∙min⁻¹; p < 0.05). Slower swimmers were older and displayed a lower EPOC amplitude than faster performers (69.8 ± 7.3 vs. 45.7 ± 1.7 years and 23.2 ± 4.0 vs. 36.8 ± 10.2 mL∙kg⁻¹∙min⁻¹; p < 0.05). Although many of the variables did not differ between groups, effect sizes were moderate to very large (except for time constant and time delay). The swimmers’ age related directly to their performance and inversely to their peak oxygen uptake, peak heart rate and EPOC amplitude, while performance presented inverse associations with peak oxygen uptake, peak heart rate, EPOC amplitude and EPOC magnitude (p < 0.05). Master swimmers of different ages and performance levels exhibited distinct EPOC characteristics, which may provide relevant information regarding the individualisation of training and recovery strategies in this population.

The 1923 Greek–Turkish Population Exchange (Mubadele in Turkish), formalized through the Lausanne Convention, remains one of the most consequential cases of compulsory migration in modern history. This systematic review synthesizes a century of scholarship across political, legal, social, cultural, and historiographical dimensions. Findings indicate that the exchange not only legitimized forced displacement under international law but also reinforced authoritarian state-building in Turkey and exacerbated political instability in Greece. The social consequences included trauma, marginalization, and the emergence of heterogeneous refugee identities, while cultural memory oscillated between nationalist silencing and transnational remembrance. Urban landscapes and demographic structures were profoundly reshaped, producing visible legacies in contemporary cities. Furthermore, assimilation policies formalized the integration of populations, influencing the development of national identities in both Turkey and Greece. Historiographical trajectories diverged, with Greek scholarship emphasizing refugee struggles and Turkish scholarship foregrounding nation-building. Recent studies highlight hybrid identities and transgenerational redefinitions of belonging. This review underscores the necessity of integrating political, social, and memory studies to capture the multi-layered impacts of the exchange, offering a comprehensive account of its enduring relevance for migration, nationalism, and memory studies in Southeast Europe.

Dysphagia and age-related oral processing limitations are rising with population aging and the growing burden of neurological diseases. Texture-modified diets remain the most common non-pharmacological intervention, yet conventional pureeing and thickening often yield meals with low visual appeal, variable textures, and diluted nutrient density, which contribute to reduced intake and malnutrition risk. Extrusion-based three-dimensional food printing, especially when combined with gel-derived edible inks, offers a digital route to standardize geometry, portioning, and texture while enabling individualized nutrition and sensory design. In the past three years, the field has progressed from simple single-ingredient pastes to engineered soft-matter systems including emulsion gels, high-internal-phase emulsion gels, Pickering-stabilized gels, bigels, and multi-material constructs enabled by dual and coaxial printing. These advances are underpinned by improved rheological windowing, microstructure engineering, and post-print gelation strategies such as ionic crosslinking, thermal setting, enzymatic bridging, and pH-triggered network formation. Meanwhile, dysphagia-oriented product development has matured from “shape recovery” demonstrations toward clinically relevant texture targets, leveraging the IDDSI tests to anchor swallowability. This review synthesizes the recent literature across materials science, food engineering, and clinical nutrition to connect gel microstructure to extrusion performance, post-processing stability, and oral processing outcomes that are relevant to older adults and dysphagia patients. We propose design principles for gel network selection, phase structuring, and process control that simultaneously satisfy print fidelity and swallowing safety targets. Full article

Screening for stomatal opening enhancers and their application via foliar spraying represents a feasible strategy to increase CO₂ assimilation flux by augmenting stomatal aperture, thereby enhancing photosynthesis and promoting plant growth. However, the lack of relevant research on forage crops has significantly limited the implementation of this strategy in forage production. In this study, using vetch (Vicia sativa) and alfalfa (Medicago sativa) as experimental materials, we first established a stable observation system tailored for evaluating stomatal opening regulation in forages: incubating abaxial epidermal peels in a solution containing 0.5% KCl (pH 6.0) under light conditions for 4 h resulted in stably opened stomata. Utilizing this system, we systematically screened the regulatory effects of 14 stomatal opening modulators, including signaling molecules, phytohormones, and amino acids. The results indicated that stomatal opening in both vetch and alfalfa exhibited pronounced concentration-dependent and species-specific responses to the modulators. Supplementation with appropriate concentrations of EGTA, GA₃, MT, His, and Pro significantly promoted stomatal opening in vetch, with increases ranging from 21% to 35%. In contrast, appropriate concentrations of Ca²⁺, H₂O₂, MJ, His, Glu, Met, Arg, and Ala effectively enhanced stomatal opening in alfalfa, with increases of 8% to 34%. To further validate the reliability of the screening system, we selected Met, which showed no regulatory effect on vetch stomata but enhanced opening in alfalfa, for foliar application validation. The results demonstrated that Met treatment had no significant effect on stomatal aperture in vetch but significantly increased it in alfalfa, consistent with the initial screening results. This consistency further confirmed the reliability of our established screening system for identifying stomatal opening enhancers in forages. Correspondingly, foliar Met application did not affect vetch growth but significantly promoted alfalfa growth, increasing biomass by 18%. In conclusion, this study established a stable screening system for stomatal opening enhancers specifically for vetch and alfalfa and successfully identified several species-specific enhancers using this system. Foliar application of these species-specific enhancers effectively increased stomatal aperture and promoted growth in target forage species, demonstrating promising potential for enhancing forage yield.

Fasciolosis is a globally prevalent trematode infection of major veterinary and public-health relevance. Juveniles migrate through liver tissue for weeks before patency, so clinically important infection may occur while faecal egg output is undetectable, complicating control and interpretation of apparent treatment failure. Triclabendazole (TCBZ) remains central because it targets both immature and adult flukes, but sustained use has been accompanied by geographically expanding reports of reduced efficacy and confirmed resistance. Most alternative fasciolicides, such as albendazole, closantel, oxyclozanide, rafoxanide, clorsulon and nitroxynil, are largely adulticidal and used alone or in combinations, yet reports of reduced efficacy/resistance are increasing worldwide. This review summarises drugs in current use and reported resistance status, and outlines a practical pathway for detecting and confirming resistance. We then appraise leading mechanistic hypotheses for TCBZ resistance as a central case study, organised around microtubule-associated phenotypes, reduced effective drug exposure, genetic architecture with tissue context, stress response and detoxification capacity, and we highlight mechanistic gaps for other fasciolicides. Finally, we discuss management implications, including monitoring-guided stewardship, stage-appropriate drug selection, rational combinations, integrated parasite management, and identify near-term priorities for harmonised surveillance, improved diagnostics and tool development. This review updates the resistance landscape and supports practical, monitoring-guided control of fasciolosis. Full article

Tuberculosis (TB) remains a major public health challenge in Peru, where interindividual variability in treatment response and drug-induced hepatotoxicity may be influenced by host genetic background. This study aimed to characterize clinically relevant polymorphisms in NAT2, CYP2E1, and SLCO1B1 in a cohort of TB patients from Southern Peru, a genetically underrepresented Andean population. Thirty-five adults receiving first-line therapy (isoniazid and rifampicin) underwent targeted Sanger sequencing of key functional variants among these three genes. NAT2 acetylator phenotypes were predominantly intermediate (68.6%), followed by rapid (20%) and slow (11.4%) profiles, with high minor allele frequencies for rs1041983 and rs1801280. CYP2E1 functional promoter variants were infrequent, whereas SLCO1B1 exhibited notable allelic heterogeneity, suggesting potential variability in rifampicin transport. Comparative analysis with previously reported Peruvian data revealed regional differences in acetylator distribution, supporting population-specific pharmacogenomic stratification. Although clinical toxicity outcomes were not evaluated, the high prevalence of reduced acetylation genotypes suggests a substantial proportion of patients may benefit from genotype-informed isoniazid dosing strategies. These findings provide foundational data for implementing precision medicine approaches using affordable and targeted technologies in TB management within Andean populations and support the integration of pharmacogenomics into national TB control programs.

Background: Nutritional status and lifestyle factors are increasingly recognized as relevant modulators of women’s reproductive health. However, data remain limited on the relationship between body composition, dietary habits, and menstrual cycle characteristics in apparently healthy young women. This study aimed to assess nutritional status, body composition, and lifestyle behaviors in young women and to explore their associations with menstrual cycle regularity. Methods: This cross-sectional study included 49 apparently healthy women aged 19–30 years. Anthropometric measurements and body composition were assessed using bioelectrical impedance analysis. Dietary habits were evaluated through a simplified food frequency questionnaire, and adherence to the Mediterranean diet was assessed using the PREDIMED score. Physical activity was estimated using MET values based on the Compendium of Physical Activities. Menstrual cycle characteristics were collected via questionnaire. Group comparisons were performed between women with regular and irregular menstrual cycles. Results: The sample was predominantly normal-weight (mean BMI 22.36 ± 4.26 kg/m²). Anthropometric and bioelectrical impedance parameters did not differ significantly between women with regular and irregular cycles. Women with irregular cycles showed higher resistance and extracellular water and lower phase angle and body cell mass, although differences were not statistically significant. A significant association was found for meat consumption, which was lower in women with irregular cycles (p = 0.007). No associations were observed for other dietary variables, physical activity, or meal frequency. Conclusions: Menstrual regularity in young women was not associated with major anthropometric differences but may be linked to subtle aspects of nutritional status and dietary habits. Lower meat consumption emerged as a potential dietary factor associated with menstrual irregularity. Although associations were modest, these findings support the relevance of nutritional and lifestyle factors in menstrual health. Larger longitudinal studies are needed to clarify these relationships. Full article

Multi-agent perception systems must operate under fundamental asymmetries: some agents provide fast but unreliable observations, while others deliver higher-quality evidence with delay and uncertain correspondence. Traditional deterministic orchestration and rule-based fusion struggle to manage these trade-offs, often producing brittle or unstable behavior. We introduce a probabilistic orchestration framework that treats coordination as an epistemic generation problem—constructing and updating belief states under uncertainty—rather than a selection problem. Instead of committing to a single agent’s output, the orchestrator constructs a belief state that explicitly represents uncertainty, evidential provenance, and temporal relevance. Decisions are produced through latency-aware, association-weighted fusion, and uncertainty itself becomes a first-class signal governing action, deferral, and learning. Crucially, the orchestrator enables controlled teacher–student adaptation: high-confidence, well-associated stationary observations are gated into a feedback loop that improves ego perception over time while mitigating error amplification. We demonstrate the approach on an infrastructure-assisted dual-camera obstacle-recognition task. Experimental results show improved robustness to distance, occlusion, and delayed evidence compared to ego-only and deterministic orchestration baselines. By operationalizing orchestration as epistemic generation, this work provides a unifying framework for robust decision-making and safe adaptation in multi-agent systems, with implications that extend beyond perception to agentic and generative AI architectures.

Irreversible anterior segment blindness with preserved retinal integrity (e.g., dense corneal opacity) remains a major clinical challenge because effective sight-restoring options are limited. Here, we describe an intraocular micro-light-emitting diode (Micro-LED) epiretinal microdisplay intended to deliver patterned optical stimulation to intact photoreceptors by bypassing opaque anterior optics. The prototype was based on a color-capable VGA microdisplay (640 × 480 pixels) and operated at <30 mW under typical conditions. An ultra-thin flexible cable and a copper-mesh–reinforced polydimethylsiloxane (PDMS) encapsulation provided a compact, conformable intraocular package with high pixel density. We evaluated a monochromatic (green) prototype in a single beagle eye $(n=1)$ using a transscleral implantation approach and performed 7 days of postoperative follow-up with slit-lamp examination and multimodal imaging. Patterned stimulation via the implanted display elicited flash-evoked visual evoked potentials (VEPs) with consistent within-session waveform morphology, providing preliminary neurophysiological surrogate evidence of upstream visual pathway activation under the tested conditions in this single-animal pilot. The short-term postoperative course included transient hypotony and anterior segment inflammation, and implant rotation with associated inferior retinal detachment was observed by day 7, highlighting current biomechanical limitations. Beyond anterior segment opacity, the same intraocular optical interface could be explored as a modular light-delivery platform to pair with emerging retinal therapies (e.g., optogenetics), pending chronic safety and functional validation. This pilot large-animal study therefore provides a translationally relevant testbed while delineating key engineering constraints that must be addressed next. Full article

Background/Objectives: The effects of silver-coated dressing on wound healing, including cytotoxicity, are controversial due to the limited and incongruous results of in vitro versus in vivo research. Multiple factors intervene in wound healing processes and scarring, including pro/anti-inflammatory and pro/anti-fibrosis markers. Herein, to elucidate reported differences between in vitro and in vivo results, the effects of silver-coated dressing on 2D and 3D mono- and cocultures of fibroblasts and adipose-derived stem cells (ADSC) were investigated. Methods: Migration profiles in 2D and 3D assays, α-smooth muscle actin and proliferation marker Ki-67 expression, TGF-β1, TGF-β3, IL-6 and IL-10 levels and/or gene expression were assessed on four culture constructs. Results: In 2D systems at 24 h, silver-treated ADSC monocultures displayed better migration abilities compared to cocultures with high fibroblast ratio. In contrast, changes in the sprouting pattern between treated and untreated samples were non-significant in 3D constructs. TGFβ-1 levels decreased post-treatment, while TGFβ-3 increased, especially in 3D models. IL-6 gene expression was up-regulated following silver exposure in 3D models, mainly for stem cells in mono- and cocultures. Conclusions: Experiment data on 3D constructs suggest that silver-coated dressings do not significant impede wound healing, whereas cytotoxic effects were more pronounced in the 2D cultures. These inconsistencies, also noted in the literature, invite a methodological discussion of the 2D setup implications, recommending 3D constructs as a more appropriate evaluation standard where observable effects are closer to in vivo conditions and more relevant for transfer to clinical applications.

The present study examined how creative intrinsic motivation (CIM), creative extrinsic motivation (CEM), and creative self-efficacy (CSE) moderate differences in individual creativity in one-on-one interactive situations. A total of 262 adults completed the Alternative Uses Task and Chinese Radical Remote Associates Test in single- and paired-player modes on an online interactive creativity task platform, followed by measures of CIM, CEM, and CSE. Participants were classified as relatively higher- versus lower-performing members within each dyad on the basis of their single-player performance. The results showed that CIM and CSE significantly moderated the fluency and originality advantages of higher divergent-thinking performers in the paired-player mode, whereas CEM did not significantly moderate performance. No significant moderating effects were found for CRRAT performance. These findings suggest that individual differences in creative motivation and creative self-efficacy are especially relevant when open-ended creative performance unfolds in interactive settings. They also imply that educators and facilitators seeking to improve collaborative creativity should attend to baseline creative ability, as well as learners’ intrinsic motivation and confidence in their creative capabilities.

Background/Objectives: Vaccination against respiratory viruses—such as respiratory syncytial virus (RSV), pneumococcal disease, influenza, and COVID-19—may reduce the risk of adverse outcomes in older adults with cardiovascular disease. This study conducted a scoping review of the effects of respiratory vaccines in older adults with cardiovascular disease. Methods: We included studies evaluating adults aged ≥ 60 years with cardiovascular disease who received different types of respiratory vaccines. Eligible designs comprised clinical trials, observational cohort studies, and other relevant studies. Editorials, commentaries, and non-original publications were excluded. A comprehensive and targeted literature search was conducted in PubMed, Scopus, EMBASE, and Web of Science from database inception through January 2026. Results: A total of 25 studies were included, encompassing 1,782,787 adults aged ≥ 60 years with cardiovascular disease who received various respiratory vaccines. RSV vaccines were associated with a lower incidence of cardiorespiratory hospitalization and stroke among vaccinated individuals. Pneumococcal vaccines showed that sequential dual vaccination strategies were associated with a lower risk of cardiovascular events. Influenza vaccination was associated with improved cardiovascular outcomes, lower mortality, and reduced adverse events. COVID-19 vaccines were associated with reductions in mortality and hospitalizations. These benefits are particularly relevant in an older population with a high burden of comorbidities; therefore, complete vaccination schedules, including booster doses, should be considered a central strategy for prevention and comprehensive management in this high-risk group. Conclusions: Vaccination against respiratory viruses in older adults with cardiovascular disease demonstrates an overall favorable/acceptable profile of efficacy and safety, with reductions in mortality, hospitalizations, and cardiovascular events, without a significant increase in serious adverse events.

Epigenetic diversity contributes to phenotypic plasticity and environmental responsiveness in Citrus spp. In this work, genome-wide DNA methylation was analyzed in 49 accessions representing six Citrus species, hybrids, varieties, and cultivars from the Greek National Germplasm Collection. Substantial variation in global DNA methylation was detected, while the epigenetic diversity indices did not differ significantly among taxa. The highest values were observed in Citrus × aurantium var. sinensis (orange) varieties (P_epi = 77.33%, Na = 1.55, h = 0.14, I_epi = 0.24), whereas the lowest were recorded in Citrus × aurantifolia (lime) (P_epi = 18.67%, Na = 0.37, h = 0.09, I_epi = 0.13), reflecting potential methylation restructuring impacted by hybridization and selection. Epigenetic and genetic diversity were significantly different. Principal coordinate analyses (PCoA) of epigenetic data revealed limited concordance to taxonomy, except for unmethylated loci, the latter exhibiting similar data to genetic (SSR) results in which groups reflected the taxonomic genealogy. Epigenetic and genetic distances were uncoupled, and associations between epigenetic diversity (P_epi, h, I_epi) and traits directly or indirectly related to fitness (fruit weight, dry matter content, ascorbic acid concentration), were weak. These findings indicate that epigenetic diversity represents an independent layer of variation in Citrus germplasm with potential relevance for breeding, conservation and environmental resilience.
