Rheumatoid arthritis (RA) is a chronic inflammatory disease of autoimmune background and unknown etiology. The importance of genetic factors in RA development is well-established. Environmental factors have also been extensively researched in relation to risk of RA and managing its symptoms. Smoking, physical activity, diet, and gut microbiota are considered to be the most essential modifiable factors in RA. Among dietary interventions, the most researched is Mediterranean diet, monounsaturated fatty acids, fish consumption, and fish oil (EPA, eicosapentaenoic acid and DHA, that is, docosahexaenoic acid). Others concerned gluten-free and vegan or vegetarian diet, salt intake, supplementation with vitamin D, antioxidants, prebiotics, and probiotics. Diet modifications can alter the gut environment, and the association between RA development or severity and the composition of gut bacteria has already been shown. This review focuses on effectiveness and usefulness of various dietary approaches and supplements in RA prevention and management, including the influence on disease activity and inflammatory status. The composition of gut microbiota and its changes in response to dietary factors are also considered. There is a great need for further research into mutual dependencies of diet, microbiome, and RA activity. The current state of knowledge provides promising evidence for future nutrition and microbial therapies. Full article

Background: Although pre-exposure prophylaxis (PrEP) has demonstrated strong clinical efficacy in preventing HIV infection among men who have sex with men (MSM), real-world utilization remains suboptimal. In South Korea, MSM constitute a major population within the domestic HIV epidemic; however, PrEP uptake has not increased pro-portionally to awareness. This discrepancy has been conceptualized as the “awareness–uptake gap,” reflecting multi-level barriers beyond individual knowledge. Purpose: This integrative review aimed to compare PrEP awareness, acceptance, and utilization among MSM populations in South Korea and international settings, and to identify structural, institutional, and psychosocial determinants contributing to the awaness, uptake gap. The study further sought to derive practical implications for nursing practice and health policy. Methods: An integrative literature review was conducted following Whittemore and Knafl’s five-step methodology and reported in line with PRISMA guidance. Electronic searches were performed in PubMed, Google Scholar, RISS, ScienceON, and DBpia for peer-reviewed studies published between 2015 and 2025 in English or Korean. The final search was completed on 31 January 2026. A total of 5952 records were identified, and 187 studies met the inclusion criteria after screening and duplicate removal. Quality appraisal was conducted using AXIS, Newcastle-Ottawa Scale, RoB 2.0, CASP, and MMAT according to study design, and the findings were synthesized within an environmental–structural–individual framework. Results: The included studies consistently showed that awareness of PrEP exceeded actual uptake. Across settings, the awareness–uptake gap was shaped by policy environment, service accessibility, stigma, privacy concerns, economic burden, institutional complexity, and provider preparedness. Comparative evidence from China, Thailand, Belgium and France, Brazil, and West Africa further suggested that awareness alone did not ensure uptake when service pathways were fragmented, culturally unsafe, or poorly understood. Conclusions: Closing the awareness–uptake gap requires integrated policy and practice strategies that extend beyond cost reduction. Strengthening confidentiality systems, simplifying service pathways, and enhancing provider competency—particularly through nurse-centered PrEP navigation and counseling models—may support more sustainable PrEP expansion among MSM populations in global settings.

Xanthomonas species are Gram-negative bacterial pathogens responsible for diseases in over 400 plant hosts, including numerous economically important crops such as Brassica species. The limited efficacy and environmental concerns associated with chemical control strategies underscore the need for sustainable and targeted alternatives. In this study, we evaluated the suitability and biocontrol efficacy of phages Phi1 and Phi3 to combat Xanthomonas campestris pv. campestris (Xcc) in broccoli plants. Kill-curve assays demonstrated that both phages effectively suppressed Xcc growth across a range of multiplicities of infection. Transmission electron microscopy further confirmed their lytic activity, revealing pronounced structural damage to Xcc cells following phage treatment, accompanied by the subsequent release of phage progeny. To assess host specificity and biosafety, the phages were tested against 41 bacterial isolates that were isolated and taxonomically characterized from broccoli and cauliflower in this study. Neither Phi1 nor Phi3 exhibited lytic activity against any non-target isolate, indicating high host specificity and minimal risk to the native Brassica-associated microbiota. In planta assays demonstrated that the combined application of Phi1 and Phi3 reduced Xcc-induced symptom severity in broccoli plants by 80%. Collectively, these results demonstrate that phages Phi1 and Phi3 represent effective and biologically precise agents for the control of black rot disease in Brassica crops. Full article

This review examines microplastics (MPs) in aquatic environments, their interactions with organic pollutants (OPs), effects on organisms, and implications for human and ecological health. MPs are ubiquitous, persistent contaminants. Their small size and large surface area enhance adsorption of diverse OPs; however, the extent to which MPs influence pollutant transport, fate, and bioavailability remains highly context-dependent and is still under scientific debate. Sorption processes are influenced by polymer type, pollutant properties, environmental factors, and aging processes that increase surface reactivity, further contributing to the variability of MP–OP interactions. Detection of MPs in human tissues raises concerns about long-term health effects, including inflammatory, immune, gastrointestinal, respiratory, and endocrine responses. Despite advances in analytical techniques, challenges remain in identifying and quantifying small particles in complex matrices. This review emphasizes the need for integrated, multi-technique, and environmentally realistic studies to understand MP–OP interactions and support risk assessment. Future research should focus on standardizing methodologies, improving nano-sized particle detection, and elucidating long-term effects, including trophic transfer and potential tissue accumulation.

(1) Background: The global educational landscape increasingly necessitates pedagogical approaches capable of addressing complex socio-environmental challenges. While STEAM education is widely adopted, its contribution to the 2030 Agenda and Global Competence requires further theoretical consolidation. This study proposes a reconceptualization of STEAM as a Transformative STEAM Framework, explicitly aligned with Sustainable Development Goals (SDGs) 4, 5, and 10, as well as the development of Global Competence. (2) Methods: Guided by PRISMA 2020 principles for study retrieval, a search for peer-reviewed research, literature reviews, and relevant institutional documents conducted in Scopus, Web of Science, and ERIC yielded a final corpus of 32 studies (2014–2024). A multi-layered methodological design was applied, integrating a Critical Interpretive Synthesis (CIS) framework for conceptual evaluation alongside a hybrid thematic synthesis to ensure rigorous data coding. (3) Results: The findings indicate that STEAM bolsters Global Competence by fostering intercultural interaction and critical thinking, demonstrating robust alignment with quality education (SDG 4) and gender equality (SDG 5). However, significant gaps remain concerning broader structural inequalities (SDG 10) and the paucity of validated, multidimensional assessment tools for evaluating Global Competence. (4) Conclusions: This review establishes a conceptual framework that positions STEAM as a catalyst for equity and the 2030 Agenda. To realize its transformative potential, future research must explicitly address the reduction in inequalities and develop robust assessment mechanisms. Full article

Based on panel data of Chinese A-share companies listed on the Shanghai and Shenzhen stock exchanges from 2006 to 2023, this study employs a staggered difference-in-differences (DID) approach to examine the impact of the Innovative Industrial Cluster (IIC) pilot policy on corporate carbon performance. The research findings indicate that the IIC pilot policy significantly enhances corporate carbon performance, a conclusion that remains robust after a series of reliability tests, including PSM-DID. Mechanism analysis demonstrates that the policy primarily operates through channels such as fostering corporate green technological innovation, increasing public environmental concern, and attracting the entry of green investors. Heterogeneity analysis further reveals that the policy effect is more pronounced among firms located in the eastern region, those in non-heavy-polluting industries, and state-owned enterprises (SOEs). This study provides micro-level evidence for understanding the green effects of industrial agglomeration and offers references for optimizing cluster policy design to facilitate the low-carbon transition.

Ship collision accidents remain a critical concern in maritime safety because of their potential to cause operational disruption as well as environmental and economic damage in areas with dense shipping activity. Complex traffic interactions, differences in vessel characteristics, and dynamic environmental conditions make collision risk increasingly difficult to manage using traditional navigation measures alone. This paper presents a structured review of ship collision research, focusing on collision impacts, collision avoidance strategies, risk assessment methodologies, and safety index development. The review synthesizes reported collision cases and their environmental consequences, examines commonly used analytical frameworks including probabilistic, data-driven, and multicriteria approaches, and discusses recent developments in AIS-based analysis, sensor-based monitoring, and intelligent prediction techniques. The analysis identifies several methodological gaps in existing studies. Collision avoidance methods and risk assessment models are often developed independently, while their integration with safety index frameworks remains limited. In addition, safety index formulations differ considerably in terms of indicator selection and modeling approaches, which reduces comparability between studies conducted in different waterways. The findings highlight how different analytical approaches contribute to maritime safety evaluation at strategic, operational, and real-time levels and provide insights for developing more integrated safety assessment frameworks to support navigation risk monitoring in high-traffic maritime environments.

Background: Cephalosporins, widely used β-lactam antibiotics, are becoming significant environmental pollutants, primarily due to their high use and persistence. They are released into the environment mainly through wastewater treatment plants, agricultural runoff, and hospital discharge, with particularly high concentrations recorded in effluents. Conventional wastewater treatment methods have inadequate removal efficiency, while advanced treatments, such as ozonation, activated carbon adsorption, and advanced oxidation processes, although more efficient, may produce toxic by-products. Recent studies emphasize the importance of improved detection and monitoring techniques and advocate for stricter effluent regulations. Despite growing research attention, important knowledge gaps remain, including limited long-term field monitoring, insufficient data on environmentally realistic exposure scenarios, and incomplete assessment of transformation-product toxicity. Methods: The search strategy used the SCOPUS and PUBMED databases with the keywords “cephalosporin” AND “aquatic environment”, resulting in 341 records. After applying predefined inclusion and exclusion criteria, 110 peer-reviewed English-language studies meeting predefined thematic inclusion criteria and relevant to the occurrence, environmental fate, ecotoxicological effects, antimicrobial resistance, and removal of cephalosporins in aquatic environments were included in the narrative synthesis. Results: The literature on cephalosporins in aquatic environments has expanded significantly from 1978 to 2025, prompted by concerns about pharmaceutical contamination and antibiotic resistance. Studies from 2016 to 2025 used advanced and multidisciplinary monitoring techniques, revealed key pollution sources such as wastewater treatment plants and hospitals, and correlated antibiotic residues with resistance genes, highlighting the need for continued monitoring and mitigation efforts. Ecotoxicological and fate studies further indicate that transformation processes may generate products with altered or increased toxicity, complicating environmental risk assessment. Conclusions: The literature shows increasing attention to cephalosporins in aquatic environments, reporting associations with antimicrobial resistance and adverse effects on aquatic organisms, including potential toxicity from transformation products. This review highlights the need for integrated monitoring, standardized toxicity assessment, and improved treatment strategies within a One Health framework. Full article

Botrytis cinerea and Plasmopara viticola, the causal agents of grey mold and downy mildew, respectively, are two major grapevine pathogens whose control largely relies on synthetic fungicides, raising environmental and health concerns. Plant-derived secondary metabolites, particularly flavonoids involved in plant defense, represent promising sustainable alternatives. Among them, sakuranetin, a flavanone aglycone known for its antifungal activity in rice, remains poorly explored for grapevine protection. In this study, sakuranetin was purified from cherry branches (48 mg) and structurally characterized using UHPLC-ESI-QTOF-MS and NMR analyses. Its antifungal activity against B. cinerea and P. viticola was evaluated through in vitro, in vivo and in planta assays. For B. cinerea, our results showed a significant in vitro inhibition of mycelium growth, with EC₅₀ values of 16.43 mg·L⁻¹, while no protection of detached berries was observed. Against P. viticola, sakuranetin has no effect on the release of zoospores, but there is a total inhibition of spore germination at 1 mg·L⁻¹ in vitro, confirmed in vivo on a foliar disc. In planta, no significant protection is observed at 25 mg·L⁻¹, even if some targeted defense genes are induced. Further studies are needed to determine the best concentration of sakuranetin to use to manage B. cinerea and P. viticola in planta. Full article

The world’s growing need for energy, fueled by industrial expansion and a rising population, continues to be a challenge for the scientific community. The heavy reliance on fossil fuels that contribute to environmental degradation and public health concerns, is shifting toward sustainable alternatives, with hydrogen production via advanced catalysts as an energy source emerging as a promising solution. This transition addresses the challenges posed by harmful combustion emissions. In this study, we developed an innovative PANI@Cu-NA-MOF nanocomposite catalyst through a sol–gel synthesis approach that strategically integrates conducting polymers with metal–organic frameworks. The catalyst was characterized using different sets of techniques. Surface morphology and elemental composition were investigated using SEM-EDX, while structural analysis was carried out with FTIR that helped to identify the chemical bonds and functional groups, and UV-Vis spectroscopy provided information on its light absorption properties. In addition, TGA was used to evaluate thermal behavior, and XPS offered detailed surface chemical analysis. It was observed by morphology that PANI@Cu-NA-MOF is a noncapsular-like structure. It is thermally highly stable; a TGA study showed that up to 550 °C, almost 2.5% of weight was lost. The single peak in UV-Vis is the preparation of a successful composite. XPS and FTIR reveal the required peaks of functional groups and elements. The PANI@Cu-NA-MOF composite turned out to be quite effective for water electrolysis, requiring an overpotential of just 0.47 V to drive the reaction. When tested against the reversible hydrogen electrode, we observed onset potentials of 1.6 V/RHE for the oxygen evolution reaction and 0.2 V/RHE for the hydrogen evolution reaction. What makes this particularly interesting is that such performance significantly cuts down on the energy needed for electrolysis, which could make hydrogen production much more practical. Since hydrogen burns cleanly and offers a real alternative to fossil fuels, having an efficient catalyst like this brings us one step closer to sustainable energy. Full article

Plastic manufacturing depends heavily on petroleum-derived monomers like terephthalic acid, the main component of polyethylene terephthalate (PET). However, the depletion of fossil resources and increasing environmental concerns have heightened the need for sustainable alternatives. Lignocellulosic biomass has emerged as a promising resource due to its renewable, abundant, and eco-friendly nature. Understanding its chemical composition enables conversion of this biomass into platform chemicals, such as 2,5-furandicarboxylic acid (FDCA) and lactic acid, derived from cellulose and hemicellulose. These can be polymerized into bio-based plastics such as polyethylene furanoate (PEF), polylactic acid (PLA), and polyhydroxyalkanoates (PHAs), offering greener alternatives to fossil-based plastics. PEF features rigid furan rings that enhance thermal stability, mechanical strength, and barrier properties, and reduce gas permeability compared to PET. PLA is a renewable, biodegradable plastic widely used in packaging and medical applications. This review covers the chemical composition of lignocellulosic biomass cellulose, hemicellulose, and lignin, and various pretreatment strategies, chemical, physicochemical, and physical, to overcome biomass recalcitrance and improve conversion efficiency. It also highlights recent catalytic advances in transforming cellulosic carbohydrates into bio-based plastic precursors such as FDCA and lactic acid. Lastly, this review discusses polymerization pathways for producing PEF and PLA, emphasizing their role in reducing the environmental impact of polymer manufacturing and promoting green chemistry principles.

Decomposition, storage and environmental conditions often leave the skeletal structure as the only basis for identification. This review synthesizes current methodologies and technological advances in damaged DNA extraction and analysis, emphasizing the forensic relevance of skeletal remains for genetic identification. Methods: A comprehensive literature analysis highlights the basis of genetic identification; sampling that considers intrinsic and extrinsic factors influencing the DNA yield and its quality; pre-treatment methods; extraction protocols that are suitable for its sensitivity; genetic marker panels that allow for human identification; and statistical evaluation and analysis of the results. The last chapter demonstrates the real-world impact of genetic identification on historical cases, underscoring its broader significance in legal, humanitarian, and socio-historical contexts, supporting a critical evaluation of best practices, methodological robustness, and ethical considerations within the field. Results: Teeth, femur and the petrous portion of temporal bone are the main samples used for genetic analysis. STR profiling and mitochondrial DNA are the gold standard markers for skeletal human identification. Minimally destructive protocols that enhance a high DNA yield are chosen, with silica-based methods being highlighted in the extraction protocols. Next-Generation Sequencing techniques have also improved analytical outcomes, by enabling high-throughput data generation, increased coverage depth, nucleotide-level sequence data, and high-level multiplexing of genetic targets. Conclusions: This review provides a comprehensive framework for researchers and practitioners seeking to optimize genetic identification workflows in forensic sciences and bioarcheology. These methodological advances have significantly increased identification success rates, especially in cases involving degraded or limited skeletal remains. Reviews such as this one help us to identify methodological gaps, ethical concerns, and future research directions, thereby establishing best practices when working with highly degraded skeletal material, supporting more reliable, standardized, and legally defensible applications of genetic identification in forensic, archeological, and humanitarian contexts.

Global interest in sustainable building materials is increasing due to growing concerns regarding the environmental impacts of conventional construction materials, particularly fired clay bricks. Compressed Stabilized Earth Blocks (CSEBs) have emerged as a viable, cost-effective, and environmentally sustainable alternative for building construction. The incorporation of waste-derived additives in CSEBs not only addresses waste management challenges but also enhances the functional performance of earthen materials. This study presents a comprehensive synthesis of existing research on the influence of fibers, binders, stabilizers, and production processes on the performance characteristics of CSEBs. A systematic literature review was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 guidelines, resulting in the identification and analysis of 256 relevant studies. The selected literature was synthesized using the Theories, Contexts, Characteristics, and Methodologies (TCCM) framework to map research trends and methodological approaches. The review indicates that fiber reinforcement primarily improves flexural strength and thermal performance, while binders significantly enhance compressive strength and erosion resistance. The findings also demonstrate that selected waste materials can partially replace natural soil, provided minimum material and performance standards are satisfied. The study highlights the need for standardized manufacturing guidelines and testing protocols to improve the reliability, scalability, and wider adoption of CSEBs in sustainable building applications.
