    Abstract Marine ecological tourism has become a popular topic in recent years, and the public's conspicuous consumption behavior is also a hot topic studied by many scholars. How to explore and stimulate the public's conspicuous consumption behavior in marine ecological tourism is an important issue that we need to address. Based on the “value-belief-norm” (VBN) theory and using the fuzzy set Qualitative Comparative Analysis (fsQCA) method, this article analyzes 462 valid samples collected through a questionnaire to explore whether the combination of VBN theory's conditional elements affects the public's conspicuous consumption behavior in marine ecological tourism. The study found that the path of public conspicuous consumption behavior has the characteristics of “different paths leading to the same destination,” that is, the combination of conditional elements from different dimensions can stimulate the goal of public conspicuous consumption behavior, and a single-dimensional conditional element is not a necessary condition to increase public conspicuous consumption behavior. Environmental values, such as biosphere values and altruistic values, significantly affect the public's conspicuous consumption behavior.

    Abstract Inspired by natural swarms, various methods are developed to create artificial magnetic microrobotic collectives. However, these magnetic collectives typically receive identical control inputs from a common external magnetic field, limiting their ability to operate independently. And they often rely on interfaces or boundaries for controlled movement, posing challenges for independent, three-dimensional(3D) navigation of multiple magnetic collectives. To address this challenge, self-assembled microrobotic collectives are proposed that can be selectively actuated in a combination of external magnetic and optical fields. By harnessing both actuation methods, the constraints of single actuation approaches are overcome. The magnetic field excites the self-assembly of colloids and maintains the self-assembled microrobotic collectives without disassembly, while the optical field drives selected microrobotic collectives to perform different tasks. The proposed magnetic-photo microrobotic collectives can achieve independent position and path control in the two-dimensional (2D) plane and 3D space. With this selective control strategy, the microrobotic collectives can cooperate in convection and mixing the dye in a confined space. The results present a systematic approach for realizing selective control of multiple microrobotic collectives, which can address multitasking requirements in complex environments.

    Abstract Many artificial miniature robotic collectives have been developed to overcome the inherent limitations of inadequate individual capabilities. However, the basic building blocks of the reported collectives are mainly in the solid state, where the morphological boundaries of internal individuals are clear and cannot genuinely merge. Miniature robotic collectives based on liquid units still need to be explored; such on-demand mergeable swarm systems are advantageous for adapting to the changing external environment. Here, a strategy to achieve a coalescent collective system we presented that exploits the ferrofluid droplets' splitting and coalescence properties to trigger the formation of horizontal multimodal and vertical gravity-resistant collectives and unveil pattern-enabled robotic functionalities. When subjected to a time-varying magnetic field, the droplet swarm exhibits a variety of morphologies ranging from horizontal collectives, including vortex-like, chain-like, and crystal-like patterns to vertical layer-upon-layer patterns. Using experiments and simulations, the formation and transformation of different morphological collectives are shown and their robust environmental adaptability are demonstrated. Potential applications of the multimodal droplet collectives are presented, including exploring an unknown environment, targeted object delivery, and fluid flow filtration in a lab-on-a-chip. This work may facilitate the design of microrobotic swarm systems and expand the range of materials for miniature robots.

    Abstract Asthma is a common chronic respiratory disease characterized by Th2-type inflammation in the airways. Leucine zip transcription factor-like 1 (LZTFL1) has been implicated in the regulation of Th2-related factors. The knockdown of LZTFL1 resulted in decreased levels of IL-4, IL-5, and IL-13. We hypothesize that LZTFL1 may have an effect on asthma. We established an acute asthmatic mouse model using the Ovalbumin (OVA) sensitization, and we found that LZTFL1 expression was upregulated in OVA-induced CD4 + T cells. Mice challenged with OVA were administered 5 × 10

    Abstract Objective: The study aimed to investigate the feasibility of establishing rhinosinusitis model in rats combinated with Lipopolysaccharide (LPS) and merocel sponge.
    Methods: SD (Sprague Dawley) rats that underwent nasal obstruction using Merocel sponge packing, rats with LPS instillation alone, and rats with both nasal obstruction and LPS instillation were used to establish rat models of rhinosinusitis. After the models were established, the nasal symptoms of rats were recorded, the histopathological examination and Transmission Electron Microscopy (TME) of the sinus tissue were performed and the levels of Tumor Necrosis Factor-α (TNF-α), Interleukin-6 (IL-6) in the blood were also analyzed. The expressions of Aquaporin-5 (AQP5), Occludin, Toll-Like Receptor-4 (TLR4), Medullary differentiation factor 88 (MyD88) and phosphorylated (p)-p65 protein were detected by Western blot to evaluate the effect and mechanism of the experimental models.
    Results: We found that compared with the control group and LPS group, the sinusitis symptom scores in the Merocel sponge combined with LPS group were significantly increased; the respiratory epithelia of the maxillary sinus were degenerated, cilia were detached, and even inflammatory cell infiltration occurred; the levels of TNF-α and IL-6 were increased; the expression of AQP5 and Occludin protein was decreased; and the expressions of TLR4, MyD88, and p-p65 protein were increased.
    Conclusion: For the first time, we successfully established a rat rhinosinusitis model using Merocel sponge with LPS and explored the possible mechanism of LPS action.

    Abstract Active matter systems feature a series of unique behaviors, including the emergence of collective self-assembly structures and collective migration. However, realizing collective entities formed by synthetic active matter in spaces without wall-bounded support makes it challenging to perform three-dimensional (3D) locomotion without dispersion. Inspired by the migration mechanism of plankton, we propose a bimodal actuation strategy in the artificial colloidal systems, i.e., combining magnetic and optical fields. The magnetic field triggers the self-assembly of magnetic colloidal particles to form a colloidal collective, maintaining numerous colloids as a dynamically stable entity. The optical field allows the colloidal collectives to generate convective flow through the photothermal effect, enabling them to use fluidic currents for 3D drifting. The collectives can perform 3D locomotion underwater, transit between the water-air interface, and have a controlled motion on the water surface. Our study provides insights into designing smart devices and materials, offering strategies for developing synthetic active matter capable of controllable collective movement in 3D space.

    Abstract To determine the protective mechanism of puerarin against nonalcoholic steatohepatitis (NASH), the pharmacodynamic effects of puerarin on NASH were evaluated by using zebrafish, cells, and mice. Western blotting, flow cytometry, immunofluorescence, and qRT-PCR were used to detect the effects of puerarin on RAW264.7 autophagy and polarization. Key target interactions between autophagy and polarization were detected using immunoprecipitation. Puerarin regulated the M1/M2 ratio of RAW 264.7 cells induced by LPS + INF-γ. Transcriptomics revealed that PAI-1 is a key target of puerarin in regulating macrophage polarization. PAI-1 knockout reduced the number of M1-type macrophages and increased the number of M2-type macrophages. Puerarin regulated PAI-1 and was associated with macrophage autophagy. It increased p-ULK1 expression in macrophages and activated autophagic flux, reducing the level of PAI-1 expression. Stat3/Hif-1α and PI3K/AKT signaling pathways regulated the number of macrophage polarization phenotypes, reducing liver lipid droplet formation, alleviating liver structural abnormalities, decreasing the number of cytoplasmic vacuoles, and decreasing the area of blue collagen in NASH mice. Puerarin is a promising dietary component for NASH alleviation.
