Background/Objectives: The social importance of health literacy (HL) is widely understood, and its measurement is the subject of various studies. Due to the recent pandemic, several instruments for measuring HL about COVID-19 have been proposed in different countries, including the HLS-COVID-Q22 questionnaire. The diversity of cultures and languages necessitates the cross-cultural adaptation of this instrument. Thus, the present study translates, adapts, and validates the psychometric properties of the HLS-COVID-Q22 questionnaire to provide its cross-cultural adaptation from English to Spanish (Peru). Methods: As part of ensuring that the final questionnaire accommodates the cultural nuances and idiosyncrasies of the target language, the following activities were carried out: (a) a survey of 40 respondents; and (b) a focus group with 10 participants, followed by expert approval. In addition, the validity and reliability of the health instrument have been ascertained through a further pilot test administered to 490 people in the city of Tacna in southern Peru. Results: The resulting questionnaire helps measure HL in Peru, aiding better-informed decision-making for individual health choices. Conclusions: The presence of such a tool is advantageous in case of similar global health emergencies, when the questionnaire can be made readily available to support a promotion of strategies towards better self-care. Moreover, it encourages other Latin American stakeholders to adjust the instrument to their own cultural, language, and socio-economic contexts, thus invigorating the regional and global expansion of the HL study network.

Brain organoid technology has revolutionized in vitro modeling of human neurodevelopment and disease, providing unprecedented insights into cortical patterning, neural circuit assembly, and pathogenic mechanisms of neurological disorders. Critically, human brain organoids uniquely recapitulate human-specific developmental processes—such as the expansion of outer radial glia and neuromelanin—that are absent in rodent models, making them indispensable for studying human brain evolution and dysfunction. However, a major bottleneck persists: Extended culture periods (≥6 months) are empirically required to achieve late-stage maturation markers like synaptic refinement, functional network plasticity, and gliogenesis. Yet prolonged conventional 3D culture exacerbates metabolic stress, hypoxia-induced necrosis, and microenvironmental instability, leading to asynchronous tissue maturation—electrophysiologically active superficial layers juxtaposed with degenerating cores. This immaturity/heterogeneity severely limits their utility in modeling adult-onset disorders (e.g., Alzheimer’s disease) and high-fidelity drug screening, as organoids fail to recapitulate postnatal transcriptional signatures or neurovascular interactions without bioengineering interventions. We summarize emerging strategies to decouple maturation milestones from rigid temporal frameworks, emphasizing the synergistic integration of chronological optimization (e.g., vascularized co-cultures) and active bioengineering accelerators (e.g., electrical stimulation and microfluidics). By bridging biological timelines with scalable engineering, this review charts a roadmap to generate translationally relevant, functionally mature brain organoids. Full article

Small towns in mountainous regions face significant challenges in formulating effective landscape zoning strategies due to pronounced landscape fragmentation, which is driven by both the dominance of large-scale forest resources and the lack of coordination between administrative planning departments. To tackle this problem, this study focused on Yuqian, a quintessential small mountainous town in Hangzhou, Zhejiang Province. The town’s layout was divided into a grid network measuring 70 m × 70 m. A two-step cluster process was employed using ArcGIS and SPSS software to analyze five landscape variables: altitude, slope, land use, heritage density, and visual visibility. Further, eCognition software’s semi-automated segmentation technique, complemented by manual adjustments, helped delineate landscape character types and areas. The overlay analysis integrated these areas with administrative village units, identifying four landscape character types across 35 character areas, which were recategorized into four planning and management zones: urban comprehensive service areas, agricultural and cultural tourism development areas, industrial development growth areas, and mountain forest ecological conservation areas. This result optimizes the current zoning types. These zones closely match governmental sustainable development zoning requirements. Based on these findings, we propose integrated landscape management and conservation strategies, including the cautious expansion of urban areas, leveraging agricultural and cultural tourism, ensuring industrial activities do not impact the natural and village environment adversely, and prioritizing ecological conservation in sensitive areas. This approach integrates spatial and administrative dimensions to enhance landscape connectivity and resource sustainability, providing key guidance for small town development in mountainous regions with unique environmental and cultural contexts.

Dark skies, a vital natural and cultural resource, have been increasingly threatened by light pollution due to rapid urbanization, leading to ecological degradation and biodiversity loss. As a key strategy for sustainable regional development, dark sky parks (DSPs) not only preserve nocturnal environments but also enhance livability by balancing urban expansion and ecological conservation. This study develops a novel framework for evaluating DSP suitability, integrating ecological and socio-economic dimensions, including the resource base (e.g., nighttime light levels, meteorological conditions, and air quality) and development conditions (e.g., population density, transportation accessibility, and tourism infrastructure). Using the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) as a case study, we employ Delphi expert consultation, GIS spatial analysis, and multi-criteria decision-making to identify optimal DSP locations and prioritize conservation zones. Our key findings reveal the following: (1) spatial heterogeneity in suitability, with high-potential zones being concentrated in the GBA’s northeastern, central–western, and southern regions; (2) ecosystem advantages of forests, wetlands, and high-elevation areas for minimizing light pollution; (3) coastal and island regions as ideal DSP sites due to the low light interference and high ecotourism potential. By bridging environmental assessments and spatial planning, this study provides a replicable model for DSP site selection, offering policymakers actionable insights to integrate dark sky preservation into sustainable urban–regional development strategies. Our results underscore the importance of DSPs in fostering ecological resilience, nighttime tourism, and regional livability, contributing to the broader discourse on sustainable landscape planning in high-urbanization contexts.

The essay offers an expansive and multi-stratified investigation into the role of esoteric traditions within the development of Russian modernity, reframing occultism not as an eccentric deviation but as a foundational epistemological regime integral to Russia’s aesthetic, philosophical, and political evolution. By analyzing the arc from Petrine-era alchemical statecraft to the techno-theurgical aspirations of Russian Cosmism and the esoteric visual regimes of the avant-garde, this essay discloses the deep ontological entanglement between sacral knowledge and modernist radical experimentation. The work foregrounds figures such as Jacob Bruce, Wassily Kandinsky, and Kazimir Malevich, situating them within broader transnational currents of Hermeticism, Theosophy, and Rosicrucianism, while interrogating the role of occult infrastructures in both late-imperial and Soviet paradigms. Drawing on recent theoretical frameworks in the global history of esotericism and modernist studies, the long-read article elucidates the metaphysical substrata animating Russian Symbolism, Abstraction, Malevich’s non-Euclidian Suprematism and Moscow Conceptualism. This study contends that esotericism in Russia—far from marginal—served as a generative matrix for radical aesthetic innovation and ideological reconfiguration. It proposes a reconceptualization of Russian cultural history as a palimpsest of submerged sacral structures, where utopia and apocalypse, magic and technology, converge in a distinctively Russian cosmopoietic horizon. Ultimately, this essay reframes Russian and European occultism as an alternate technology of cognition and a performative semiotic universe shaping not only artistic modernism but also the very grammar of Russian historical imagination.

Human adipose-derived stem cells (hASCs) are widely used in regenerative medicine due to their accessibility and high proliferative capacity. Platelet lysate (PL) has recently emerged as a promising alternative to fetal bovine serum (FBS), offering superior cell expansion potential; however, the molecular basis for its efficacy remains insufficiently elucidated. In this study, we performed RNA sequencing to compare hASCs cultured with PL or FBS, revealing a significant upregulation of genes related to stress response and cell proliferation under PL conditions. These findings were validated by RT–qPCR and supported by functional assays demonstrating enhanced cellular resilience to oxidative and genotoxic stress, reduced doxorubicin-induced senescence, and improved antiapoptotic properties. In a murine wound model, PL-treated wounds showed accelerated healing, characterized by thicker dermis-like tissue formation and increased angiogenesis. Immunohistochemical analysis further revealed elevated expression of chk1, a DNA damage response kinase encoded by CHEK1, which plays a central role in maintaining genomic integrity during stress-induced repair. Collectively, these results highlight PL not only as a viable substitute for FBS in hASC expansion but also as a bioactive supplement that enhances regenerative efficacy by promoting proliferation, stress resistance, and antiaging functions.

With increasing attention on DNA ancestry tests, scholars have explored how these tests inform modern understandings of race. Current research reveals the flaws and misinterpretations that arise when DNA tests, such as those offered by 23andMe and AncestryDNA, are used as a proxy for racial identity. While prominent in popular culture, the legitimacy and implications of these tests remain contested in the scholarly literature. Some researchers have explored how the increased availability of DNA tests affects how multiracial individuals identify and disclose their racial and ethnic identities, though this exploration remains limited. As discourse about mixed race identity and ancestry tests becomes more nuanced, I argue for the utility of using diunital perspectives, an expansive lens that resists either/or thinking, to complicate conversations about ancestry tests and multiraciality. This scholarly essay integrates personal narrative and a genealogical deconstruction of monoracialism to explore the question, “How can DNA tests contribute to the unlearning of monoracialism?” I share two personal vignettes to illustrate how these tests can reveal a preference for discrete racial categories. Drawing from Critical Race Theory, strategic essentialism, and diunital perspectives, I examine how DNA tests intersect with identity, family, and monoracialism, concluding with implications for disrupting monoracial logics.

Highway construction in China has bolstered Chinese claims of having the longest highways in the world, yet it has led to the involuntary relocation and resettlement of millions of people all over China. This study examines the interplay of power relationships in modernity and ethnic cultures. Using interviews with 201 Zhuang ethnic minority people and participant observations from two years in the Southwest of China, this paper presents findings that show both the positive and negative effects of urbanization and modernization as the consequence of highway expansion. By discussing the removal of a religious Sacred Rock which was in the way of the highway construction, the authors reveal the subtleties of the power interplay of majority–minority relations and the meanings of cultures and rituals in the face of modernity. In the process of modernization, highway construction reconstructs new communities while deconstructing the old one. The authors argue that recognizing the meanings of ethnic cultures as defined by ethnic people themselves is the first step to the reconciliation of social relationships between the majority and minority people in created new communities. To enhance social integration, religion has an important role to play in Chinese society. Full article

Indigenous students remain significantly underrepresented in medical education, contributing to persistent health inequities in their communities. Systemic barriers, including cultural isolation, inadequate resources, and biased curricula, hinder their success. But what if generative artificial intelligence (GAI) could be the game-changer? This scoping review explores the potential of generative artificial intelligence (GAI) in making medical education more inclusive and supportive for Indigenous students through a comprehensive analysis of existing literature. From AI-powered engagement platforms to personalised learning systems and immersive simulations, GAI can be harnessed to bridge the gap. While GAI holds promise, challenges like biased datasets and limited access to technology must be addressed. To unlock GAI’s potential, we recommend faculty development, expansion of digital infrastructure, and Indigenous-led AI design. By carefully harnessing GAI, medical schools can take a crucial step towards creating a more diverse and equitable healthcare workforce, ultimately improving health outcomes for Indigenous communities.

Oases in arid regions are critical ecosystems, providing essential ecological, agricultural, and socio-economic functions. However, urbanization and climate change increasingly threaten their sustainability. This study examines land cover (LULC) and land surface temperature (LST) dynamics in four representative North African oases: Tolga (Algeria), Nefta (Tunisia), Ghadames (Libya), and Siwa (Egypt) over the period 2000–2023, using Landsat satellite imagery. A three-step analysis was employed: calculation of NDVI (Normalized Difference Vegetation Index), NDBI (Normalized Difference Built-up Index), and LST, followed by supervised land cover classification and statistical tests to examine the relationships between the studied variables. The results reveal substantial reductions in bare soil (e.g., 48.10% in Siwa) and notable urban expansion (e.g., 136.01% in Siwa and 48.46% in Ghadames). Vegetation exhibited varied trends, with a slight decline in Tolga (0.26%) and a significant increase in Siwa (+27.17%). LST trends strongly correlated with land cover changes, demonstrating increased temperatures in urbanized areas and moderated temperatures in vegetated zones. Notably, this study highlights that traditional urban designs integrated with dense palm groves significantly mitigate thermal stress, achieving lower LST compared to modern urban expansions characterized by sparse, heat-absorbing surfaces. In contrast, areas dominated by fragmented vegetation or seasonal crops exhibited reduced cooling capacity, underscoring the critical role of vegetation type, spatial arrangement, and urban morphology in regulating oasis microclimates. Preserving palm groves, which are increasingly vulnerable to heat-driven pests, diseases and the introduction of exotic species grown for profit, together with a revival of the traditional compact urban fabric that provides shade and has been empirically confirmed by other oasis studies to moderate the microclimate more effectively than recent low-density extensions, will maintain the crucial synergy between buildings and vegetation, enhance the cooling capacity of these settlements, and safeguard their tangible and intangible cultural heritage.

Miami, Florida, renowned for its cultural richness and coastal beauty, also faces the concerning challenges created by urban heat islands (UHIs). As one of the hottest cities of the United States, Miami is facing escalating temperatures and threatening heat-related vulnerabilities due to urbanization and climate change. Our study addresses the critical issue of mapping and investigating UHIs in complex urban settings. This study leveraged Planet satellite data and Landsat data to conceptualize and develop appropriate mitigation strategies for UHIs in Miami. Utilizing the Planet satellite imagery and Landsat data, we conducted a combined study of land cover and land surface temperature variations within the city. This approach fuses remotely sensed data to identify the UHI hotspots. This study aims for dynamic approaches for UHI mitigation. This includes studying the status of green spaces present in the city, possible expansion of urban green spaces, the propagation of cool roof initiatives, and exploring the recent climatic trend of the city. The research revealed that built-up areas consistently showed higher land surface temperatures while zones with dense vegetation have lower surface temperatures, supporting the role of urban green spaces in surface temperature reduction. This research can also set a robust model for addressing UHIs in other cities facing rapid urbanization and experiencing mounting temperatures each passing year by helping in assessing LST, land cover, and related spectral indices as well.

The ability to study mature neuronal cells ex vivo is complicated by their non-dividing nature and difficulty in obtaining large numbers of primary cells from organisms. Thus, numerous transformed progenitor models have been developed that can be routinely cultured, then scaled, and differentiated to mature neurons. In this paper, we present a new method for differentiating one such model, the Lund human mesencephalic (LUHMES) dopaminergic neurons. This method is two days faster than some established protocols, results in nearly five times greater numbers of mature neurons, and involves fewer handling steps that could introduce technical variability. Moreover, it overcomes the problem of cell aggregate formation that commonly impedes high-resolution imaging, cell dissociation, and downstream analysis. While recently established for herpes simplex virus type 1, we demonstrate that LUHMES neurons can facilitate studies of other herpesviruses, as well as RNA viruses associated with childhood encephalitis and hemorrhagic fever. This protocol provides an improvement in the generation of large-scale neuronal cultures, which may be readily applicable to other neuronal 2D cell culture models and provides a system for studying neurotrophic viruses. We named this method the Streamlined Protocol for Enhanced Expansion and Differentiation Yield, or SPEEDY, method. Full article

China’s rapid urbanization has given rise to the phenomenon of “urban villages”, which are often regarded as chaotic fringe areas in traditional studies. With the rise of the concept of resilient cities, the value of urban villages as potential carriers of sustainable development has been re-examined. This study adopted research methods such as field investigations, in-depth interviews, and conceptual sampling. By analyzing the interlinked governance relationship between Xiamen City and the urban villages in the Bay Area, aspects such as rural housing improvement, environmental governance, residents’ feedback, geographical pattern, and spatial production were evaluated. A field investigation was conducted in six urban villages within the four bays of Xiamen. A total of 45 people in the urban villages were interviewed, and the spatial status of the urban villages was recorded. This research found that following: (1) Different types of urban villages have formed significantly differentiated role positionings under the framework of regional governance. Residential community types XA and WL provide long-term and stable living spaces for migrant workers in Xiamen; tourism development types DS, HX, BZ, and HT allow the undertaking of short-term stay tourists and provide tourism services. (2) These urban villages achieve the construction of their resilience through resisting risks, absorbing policy resources, catering to the expansion of urban needs, and co-construction in coordination with planning. The multi-cultural inclusiveness of urban villages and their transformation led by cultural shifts have become the driving force for their sustainable development. Through the above mechanisms, urban villages have become the source of resilience and sustainability of healthy cities and provide a model reference for high-density urban construction. Full article

The agricultural products trade network is essentially a complex adaptive system formed by nonlinear interactions between countries. Based on the complex system theory, this study reveals the dynamic self-organization law of the RCEP regional agricultural products trade network by using the panel data of RCEP agricultural products export trade from 2000 to 2023, combining social network analysis (SNA) and the temporal exponential random graph model (TERGM). The results show the following: (1) The RCEP agricultural products trade network presents a “core-edge” hierarchical structure, with China as the core hub to drive regional resource integration and ASEAN countries developing into secondary core nodes to deepen collaborative dependence. (2) The “China-ASEAN-Japan-Korea “riangle trade structure is formed under the RCEP framework, and the network has the characteristics of a “small world”. The leading mode of South–South trade promotes the regional economic order to shift from the traditional vertical division of labor to multiple coordination. (3) The evolution of trade network system is driven by multiple factors: endogenous reciprocity and network expansion are the core structural driving forces; synergistic optimization of supply and demand matching between economic and financial development to promote system upgrading; geographical proximity and cultural convergence effectively reduce transaction costs and enhance system connectivity, but geographical distance is still the key system constraint that restricts the integration of marginal countries. This study provides a systematic and scientific analytical framework for understanding the resilience mechanism and structural evolution of regional agricultural trade networks under global shocks.

With the rapid expansion of higher education in China, university teachers are facing increasing workloads and mounting performance pressures, posing significant threats to their occupational health. Consequently, how to enhance job performance while safeguarding faculty well-being has become a critical issue for higher education administrators. This study aims to explore the role of health-promoting leadership (HPL) in addressing the dual challenge of enhancing university teachers’ job performance while maintaining their occupational health. Drawing on the Conservation of Resources (COR) theory, this study conceptualizes job burnout as both a core indicator of occupational health and a mediating variable, as well as proposing a dual-path model to examine the direct and indirect effects of HPL on teachers’ job performance. A survey of 556 university teachers in Jiangxi Province, China, was conducted; the data were analyzed using IBM SPSS Statistics version 22.0 and AMOS version 26.0 (IBM Corp., Armonk, NY, USA). The findings suggest that HPL is positively associated with job performance, both directly and indirectly through reduced burnout, supporting a dual-pathway mechanism consistent with COR theory. These results contribute to a better understanding of the potential role of HPL in balancing teacher well-being and performance in the context of Chinese higher education. This study also extends the cross-cultural application of COR theory and provides theoretical and practical insights into how HPL may help alleviate teacher burnout and support the development of health-promoting universities.
