A Chinese drug-compatibility-based approach to purslane hydrogels for acute eczema therapy

Purslane (Portulaca oleracea L.) with heat-clearing and detoxicating, anti-inflammatory and resolving swelling, relieving itching and astringing function, has remarkable efficacy for acute eczema. However, most of the clinical applications of purslane are freshly prepared decoction, not as easy to apply as cream, because the decoction is easy to breed bacteria and easy to oxidize. Here, based on the theory of Chinese medicines compatibility, we made a purslane-tannic acid hydrogel (PL-HATA) by simple methods under mild conditions to solve the drawbacks of easy oxidation and inconvenience of use of Purslane. The antimicrobial activity of PL-HATA hydrogel can exert an excellent antimicrobial effect, reducing the flora on the skin of acute eczema and further relieving the symptoms of acute eczema. At the same time, it creates a normal reactive oxygen species (ROS) microenvironment for acute eczema and promotes recovery from acute eczema. It also improves the symptoms of acute eczema by promoting cell proliferation and migration. Importantly, it resulted in improved skin lesion scores, scratching behavior, eosinophil infiltration, swelling and inflammation levels, immune homeostasis, and histopathological changes in rats with acute eczema. Besides, HATA hydrogel is not only suitable for Purslane’s decocted metabolites but also for Purslane’s freshly squeezed metabolites. This purslane application protocol solved the drawbacks of Purslane’s decoction, improved its storage stability and convenience of use, which is the key issue to further promote its clinical application.

Unveiling the Mechanism of Compound Ku-Shen Injection in Liver Cancer Treatment through an Ingredient-Target Network Analysis.

Compound Ku-Shen Injection (CKI) is a traditional Chinese medicine preparation derived from Ku-Shen and Bai-Tu-Ling, commonly used in the adjunctive treatment of advanced cancers, including liver cancer. However, the underlying mechanisms of CKI's effectiveness in cancer treatment are not well defined. This study employs network pharmacology to investigate the traditional Chinese medicine (TCM) compatibility theory underlying CKI's action in treating liver cancer, with findings substantiated by molecular docking and in vitro experiments. Sixteen active components were identified from CKI, along with 193 potential targets for treating liver cancer. Key therapeutic target proteins, including EGFR and ESR1, were also identified. KEGG enrichment results showed that the neuroactive ligand-receptor interaction, cAMP signaling pathway, and serotonergic synapses make up the key pathway of CKI in the treatment of liver cancer. Molecular docking results confirmed that the key active ingredients effectively bind to the core targets. CCK-8 cytotoxic experiment results show that the CKI key components of oxymatrine and matrine can inhibit the growth of HepG2 liver cancer cell proliferation. A Western blot analysis revealed that oxymatrine suppresses the expression of EGFR, contributing to its therapeutic efficacy against liver cancer. our study elucidated the therapeutic mechanism of CKI in treating liver cancer and unveiled the underlying principles of its TCM compatibility through its mode of action.

A mathematical multiple-dimensional strategy for Q-markers identification based on “five principles”: Tianshu Capsule for migraine treatment as an example

Ethnopharmacological relevanceQuality control is a critical element for Traditional Chinese medicine (TCM). Due to the varied chemical components, mechanisms of action, and pharmacological functions in TCM, ensuring quality is more challenging compared to chemical drugs. Then, the concept of quality markers (Q-markers) was proposed and ideal Q-markers for TCM prescriptions need to compliant with “five principles”, including pharmacological effectiveness, specificity, transfer and traceability, measurability, and prescription compatibility. Aim of the studyTo establish a mathematical multiple-dimensional “spider-web” strategy and identify the Q-markers of Tianshu capsule (TSC), a Chinese patent medicine for the treatment of migraine, following the “five principles” rules. Materials and methodsQ-marker candidates of TSC were firstly screened according to the HPLC fingerprints. Their contents in 10 batches of TSC and stabilities under high temperature, high humidity and in work solutions were determined quantitatively by HPLC-UV (measurability). Their existences in Gastrodiae Rhizoma, Chuanxiong Rhizoma, TSC, rat plasma and brain samples were investigated using HPLC-Q-TOF/MS (transfer and traceability). Their anti-migraine efficacies were evaluated by network pharmacology and mice hot-plate analgesia test; and their relationships with the property (flavor) of Gastrodiae Rhizoma or Chuanxiong Rhizoma were studied by molecular docking (effectiveness). Their contributions were defined based on their herb source according to the compatibility theories of Da Chuan Xiong Fang (compatibility). Their biosynthetic pathways were studied, and their frequencies detected in different plant families were calculated (specificity). Finally, an eight dimensional “spider-web” mode was developed for 10 components, and the regression area (RA) and the coefficient variation (CV) of each candidate were calculated after data normalization. ResultsTen components including gastrodin, parishin E, chlorogenic acid, ferulic acid, isochlorogenic acid A, senkyunolide I, H, A, Z-ligustilide and levistilide A were selected and evaluated as the Q-marker candidates. The results showed that gastrodin, senkyunolide I, and senkyunolide A had the higher RA and lower CV than other compounds with the established “spider-web” mode, indicating that they could be used as the Q-markers of TSC. ConclusionThe multi-dimensional “spider-web” mode based on “five principles” was firstly applied to identify the Q-markers of TSC, and it can be used as a practical strategy to discover Q-markers of other compounded prescriptions.

The Inhibitory Impact of a Co-Assembly Gel with Natural Carrier-Free Binary Small Molecules, as Used in Traditional Chinese Medicine, on the Viability of SW1990 Cells.

Chinese herbs are a huge treasure trove of natural products and an important source of many active molecules. The theory of traditional Chinese medicine compatibility (TCMC) is widely applied in clinical practice, but its mechanism is still ambiguous. This study aims to open a new window for this predicament by studying the interaction between the main active ingredients from a drug pair. Carrier-free assembly of natural products improves the shortcomings of traditional nanodelivery systems and opens a new path for the development of new nanomaterials. The drug pair "Pueraria and Hedyotis diffusa" has been commonly used in clinical practice, with a predominant therapeutic effect. This study is devoted to the study of the binary small molecule co-assembly of the main active molecules from the drug pair. In this study, we introduce a carrier-free composite gel, formed by the co-assembly of puerarin (PUE) and deacetylasperulosidic acid (DAA) via non-covalent bonds including π-π packing, intermolecular hydrogen bonding, and C=O π interactions. With a strain point 7-fold higher than that of P gel, the P - D gel exhibited favorable rheological properties. The survival rate of SW1990 cells in the P - D group was only 21.39% when the concentration of administration reached 200 μM. It thus demonstrated activity in inhibiting SW1990 cells' survival, suggesting potential in combating pancreatic cancer. Furthermore, this research offers a valuable concept for enhancing the mechanical properties and bioactivity of hydrogel materials through the utilization of a multi-component natural small molecule co-assembly approach. More importantly, this provides new ideas and methods for the treatment of pancreatic cancer and the analysis of traditional Chinese medicine compatibility theory.

Effects of herbal formula on growth performance, apparent digestibility, antioxidant capacity, and rumen microbiome in fattening lambs under heat stress.

Heat stress (HS) causes severe economic losses in sheep industry worldwide. The objective of the present study was to investigate the effects of a herbal formula (HF) supplement on growth, digestibility, antioxidant capacity, and rumen microbes in fattening lambs under HS. The HF composed of four herbs was prepared based on the theory of compatibility of Chinese medicine "Jun-Chen-Zuo-Shi". Two-hundred forty 3-month weaned lambs (initial weight 36.61 ± 0.73kg) were randomly allocated into four groups, supplemented 0% (Control), 0.5%, 1.0%, and 1.5% HF in diets. All lambs were exposed to HS conditions with 79.7 of average temperature-humidity index throughout an experimental period of 35days. Growth performance, apparent digestibility, and antioxidant activities, involving antioxidant enzymes and heat shock proteins (HSPs), were measured at the end of trial, as well as microbial communities in bacteria and archaea. Results showed that 0.5% HF increased (P = 0.02) average daily gain by 13.80% and decreased feed-to-gain ratio (P = 0.03) by 14.68%, compared to control. With increasing HF doses, the digestibility of ether extract and acid detergent fiber demonstrated a cubical (P < 0.01) and quadratic (P = 0.03) relation, respectively; moreover, glutathione peroxidase and catalase activities demonstrated a quadratic increase (P < 0.01). Serum levels of HSP60, HSP70, and HSP90 for 0.5% HF were lower than that in control (P < 0.05). On the other hand, total volatile fatty acid, acetic acid, butyric acid, valeric acid, and isovaleric acid levels exhibited quadratic increases (P ≤ 0.01) with HF doses. From rumen microbes, the abundance and diversity of bacterial community were improved by HF supplements. Particularly for 0.5% HF group, the operational taxonomic units were the greatest among all groups. Compared to control, Prevotella abundance for HF supplements from 0.5 to 1.5% increased by 35.57 to 60.15%, and Succiniclasticum abundance demonstrated a quadratic pattern (P = 0.02) with doses. Additionally, Methanosphaera abundance in archaeal community raised by 0.2 to 3.3-folds when lambs were fed the HF additions of 0.5 to 1.5%. In summary, dietary HF supplements would contribute to alleviating HS in lambs, and our results suggest the optimal dose of 0.5% HF supplement in diet.

The rigid-flexible balanced molecular crosslinking network transition interface: An effective strategy for improving the performance of bamboo fibers/poly(butadiene succinate-co-butadiene adipate) biocomposites

The poor interfacial compatibility of natural fiber-reinforced polymer composites has become a major challenge in the development of industry-standard high-performance composites. To solve this problem, this study constructs a novel rigid-flexible balanced molecular crosslinked network transition interface in composites. The interface improves the interfacial compatibility of the composites by balancing the stiffness and strength of the fibers and the matrix， effectively improving the properties of the composites. The flexural strength and flexural modulus of the composites were enhanced by 38 % and 44 %, respectively. Water absorption decreased by 30 %. The initial and maximum thermal degradation temperatures increased by 20 °C and 16 °C, respectively. The maximum storage modulus increased by 316 %. Furthermore, the impact toughness was elevated by 41 %, attributed to the crosslinked network's efficacy in absorbing and dissipating externally applied energy. This innovative approach introduces a new theory of interfacial reinforcement compatibility, advancing the development of high-performance and sustainable biocomposites.

Supramolecular prodrug inspiring from Rhizoma Coptidis - Fructus Mume herbal pair alleviated inflammatory diseases by inhibiting pyroptosis

Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 ratio, driven by electrostatic interactions, hydrophobic interactions and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and Lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase11.

Sadness and fear, but not happiness, motivate inhibitory behaviour: the influence of discrete emotions on the executive function of inhibition

ABSTRACT Inhibition, an executive function, is critical for achieving goals that require suppressing unwanted behaviours, thoughts, or distractions. One hypothesis of the emotion and goal compatibility theory is that emotions of sadness and fear enhance inhibitory control. Across Experiments 1–4, we tested this hypothesis by inducing a happy, sad, fearful, and neutral emotional state prior to completing an inhibition task that indexed a specific facet of inhibition (oculomotor, resisting interference, behavioural, and cognitive). In Experiment 4, we included an anger induction to examine whether valence or motivational-orientation best-predicted performance. We found support that fear and sadness enhanced inhibition except when inhibition required resisting interference. We argue that sadness and fear enhance inhibitory control aiding the detection and analysis of problems (i.e. sadness) or threats (i.e. fear) within one’s environment. In sum, this work highlights the importance of identifying how negative emotions can be beneficial for and interact with specific executive functions influencing down-stream processing including attention, cognition, and memory.

Investigation of the mechanism of nephrotoxicity of nux-vomica by PTGS2/CYP2C9-mediated arachidonic acid pathway and Jian Pi Tong Luo compound's protective effect.

The clinical effectiveness of nux-vomica in treating rheumatism and arthralgia is noteworthy; however, its nephrotoxicity has sparked global concerns. Hence, there is value in conducting studies on detoxification methods based on traditional Chinese medicine compatibility theory. Blood biochemistry, enzyme-linked immunosorbent assay, and pathological sections were used to evaluate both the nephrotoxicity of nux-vomica and the efficacy of the Jian Pi Tong Luo (JPTL) compound in mitigating this toxicity. Kidney metabolomics, using ultra-high-performance liquid chromatography-quadrupole-time-of-flight-MS (UPLC-Q-TOF-MS), was applied to elucidate the alterations in small-molecule metabolites in vivo. In addition, network pharmacology analysis was used to verify the mechanism and pathways underlying the nephrotoxicity associated with nux-vomica. Finally, essential targets were validated through molecular docking and western blotting. The findings indicated significant nephrotoxicity associated with nux-vomica, while the JPTL compound demonstrated the ability to alleviate this toxicity. The mechanism potentially involves nux-vomica activating the "PTGS2/CYP2C9-phosphatidylcholine-arachidonic acid metabolic pathway." This study establishes a scientific foundation for the clinical use of nux-vomica and lays groundwork for further research and safety assessment of toxic Chinese herbal medicines.

Compatibility with Fructus Ligustri Lucidi Effectively Mitigates Idiosyncratic Liver Injury of Epimedii Folium by Modulating NOD-like Receptor Family Pyrin Domain Containing 3 Inflammasome Activation

Abstract Background: Idiosyncratic drug-induced liver injury (IDILI) is a serious side effect of drugs, Epimedii Folium (EF) is unequivocally implicated in idiosyncratic liver injury onset, potentially due to its ability to perturb the NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome. Fructus Ligustri Lucidi (FLL), a frequently used medicinal combination with EF, has not yet been investigated for its ability to ameliorate EF-associated hepatotoxicity. Aims and Objectives: Study on the mechanism of compatibility of FLL to alleviate liver injury caused by EF. Materials and Methods: Western blot was used to determine the expression of related proteins, ELISA was used to detect the secretion of related inflammatory factors IL-1β, IL-18, IL-6 and TNF-α, liver injury indexes were detected and liver pathological tissue staining was used to evaluate the liver injury. Results: Our results demonstrated that EF exerted a particular augmenting effect on the stimulation of the NLRP3 inflammasome mediated by nigericin or ATP, whereas FLL suppressed the NLRP3 inflammasome stimulation. Furthermore, an equal EF to FLL ratio significantly reduced the stimulatory effects of EF. Moreover, EF has the potential to induce hepatic injury and augment pro-inflammatory cytokine synthesis in rats subjected to LPS. However, when combined with FLL, the detrimental effects of EF were mitigated. Conclusions: FLL possesses the capacity to attenuate EF-associated hepatotoxicity by suppressing EF-triggered NLRP3 inflammasome activation. Thus, FLL holds promise for improving the clinical safety profile of EF, shedding light on the potential of compatibility and detoxification theories in traditional Chinese medicine.

Grand herringbone architecture securing the high thermoelectric performance of GeTe

This work demonstrates a unique two-stage cooling procedure for synthesizing high-performance thermoelectric (TE) GeTe alloys with a maximum zT value of 2.0 (720 K) without assistance of chemical doping. The efficiency breakthrough stems from the grand herringbone structure resulted from the annealing step intentionally inserted near the phase transition temperature Tc of GeTe when cooling. Compared with the samples prepared by conventional methods, the two-stage cooled GeTe processes not only lower carrier concentrations p (4.7–5.3 × 1020 cm−3) but also higher mobility (∼125 cm2 V−1 s−1) that prevent electrical conductivity and TE power factor from declining as p decreases. The twinned domains in the two-stage cooled samples are further analyzed and classified by the compatibility theory. Our calculations show that the twinning structures in the two-stage cooled samples fit well with the compatibility criterion for twin variant selections and are thermodynamically in a stable state. These results not only attest to the efficacy of using the two-stage cooling procedure to manipulate the microstructures of GeTe but also provides a new paradigm for optimizing the performance of GeTe-based TE materials.

How Tort Can Address Historical Injustice

How Tort Can Address Historical Injustice Recent years have seen an increase in civil litigation of cases of systemic and historical injustice in the Netherlands. Cases regarding war crimes, genocide and other human rights violations in the past and present have reached the Dutch civil courts through tort law. Meanwhile, scholarly disciplines have difficulty understanding the match between tort law and historical injustice cases, distracted by tort’s technicalities and alleged formality. This article provides an interdisciplinary analysis aiming to theoretically clarify the urgency and aspiration put on tort by the slavery justice movement: what potential does tort hold for addressing historical injustice, such as slavery? The article identifies ‘talking points’ between two compatible theories from the sociological and legal disciplines, transformative justice and civil recourse theory, illustrated with cases of systemic and historical injustice. It argues that despite difficulties, tort litigation can be a viable platform to address historical injustices such as colonial slavery. This impact is not dependent on a successful legal outcome: the process can foster agency through process, and participation through inclusion, as core characteristics of remedying historical injustice.

Robust optimization of multi-objective multi-cycle remanufacturing supply chain network considering incentive compatibility theory under improved algorithm

In recent years, industrial production and transportation have generated a significant amount of carbon emissions, leading to a heightened focus on environmental resource conservation. Concurrently, with the development of internet technologies, an increasing number of enterprises are leveraging big data and artificial intelligence for production and logistics. Within this context, the challenge of how enterprises can utilize big data services to reduce costs while minimizing carbon emissions has become a pressing concern. Meanwhile, remanufacturing, as a sustainable solution, has garnered substantial attention. However, remanufacturing supply chain networks become exceptionally complex and challenging when faced with uncertainties in demand and recovery quantities, necessitating government intervention. Thus, to examine the impact of government intervention on the optimization of green remanufacturing supply chain networks, this paper, based on incentive compatibility theory, establishes an optimization function with objectives of minimizing total cost, reducing carbon emissions, and maximizing return on data investment in scenarios marked by uncertain market demand and recovery quantities. It constructs multi-objective fuzzy optimization models for various scenarios. The paper employs improved robust optimization to address uncertainties related to demand and recovery quantities. It also utilizes the Improved Multi-Objective Genetic Algorithm (IMOGA) to address multi-objective optimization, addressing the limitations of Genetic Algorithms (GA) and Multi-Community particle swarm optimization (MPSO). Case study results indicate that robust optimization effectively handles uncertainties in the model, aligning better with real-world conditions. High-tech enterprises often prioritize economic objectives, and government intervention measures can compensate for their limited carbon reduction capabilities. In most cases, the improved multi-objective genetic algorithm (IMOGA) outperforms MPSO and GA in terms of performance. In the context of the evolving internet landscape, high-tech enterprises should harness big data and artificial intelligence to establish green remanufacturing supply chain networks. Simultaneously, government guidance to reduce carbon emissions is instrumental in enhancing corporate competitiveness and industrial upgrading.

Developing Mathematics Achievement and Inductive Reasoning: A Proposed Technique According to Brain Compatible Learning Theory

Recent research has shown the need to present knowledge to students in a manner consistent with the characteristics of the human brain, especially during learning mathematics, which contributes to the development of achievement and inductive reasoning. The current study aimed to develop achievement and inductive reasoning by employing brain-compatible learning theory in teaching and learning mathematics for sixth-grade students in Oman. The sample included (74) students, who were divided into two equal groups: experimental and control. Study data were collected using mathematical achievement tests and inductive reasoning. There were significant differences between the two groups in the post-application of the achievement and inductive reasoning tests in favor of the experimental group, which indicates that teaching mathematics according to the theory of learning compatible with the brain had a significant impact on the development of achievement and inductive reasoning among the participants. The study recommended the need to develop and teach mathematics curricula in a way that allows for the practice of many activities and exercises that contribute to the development of students’ achievement and inductive reasoning skills.

Synergistic and attenuated effects and molecular biological mechanisms of Shouhui Tongbian capsule in the treatment of slow transit constipation based on UPLC-MS/MS, network pharmacology and animal experimental validation

BackgroundShouhui Tongbian capsule (SHTB) has been widely used for the treatment of constipation. There are few studies on SHTB at present. The current study aimed to explore the effects of multi-components compatibility of SHTB for efficacy enhancement and toxicity reduction and evaluate its molecular biological mechanisms in the treatment of slow transit constipation (STC). MethodsUltraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to quantify 17 anthraquinone components in different compatible systems of SHTB. Network pharmacological analysis was used to probe the potential mechanisms of SHTB in treating STC. In addition, an animal experiment combined with western blot analysis was performed to further validate the predicted results. ResultsAfter compatibility, the dissolution of 13 components with good effects in treating constipation increased, while the dissolution of 3 components with hepatotoxicity decreased. Overall, 145 common targets of 13 synergistic components and constipation were identified. A synergistic component-target-disease network showed that chrysoobtusin, obtusifolin, emodin, obtusin and 2-hydroxyl emodin-1-methyl ether were the potential key synergistic components. A protein-protein interaction network analysis identified 91 targets, and an analysis of topological characteristics was conducted to confirm the core targets. Gene Ontology function revealed that the 13 synergistic components for the treatment of STC mainly played roles via protein phosphorylation, positive regulation of phosphorylation, phosphotransferase activity, kinase activity and protein kinase activity, and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that these components were enriched in pathways in cancer, MAPK signaling pathway, IL-17 signaling pathway, NF-κB signaling pathway, etc. The results of animal experimental validation showed that SHTB significantly reduced the expression levels of p-p38 and p-ERK proteins in the colon tissue of the STC rats. ConclusionThis study preliminarily demonstrated that efficacy enhancement and toxicity reduction of SHTB could be achieved after compatibility, which expounded the connotation of compatibility theory of traditional Chinese medicine from the perspective of chemical composition, reflecting the rationality and scientificity of compatibility theory. Meanwhile, the study also revealed the core targets and potential molecular biological mechanisms of SHTB in the treatment of STC, which may serve as a reference for subsequent studies and clinical applications of SHTB.

Underappreciated microplastic galaxy biases the filter-based quantification

Long-term environmental loading of microplastics (MPs) causes alarming exposure risks for a variety of species worldwide, considered a planetary threat to the well-being of ecosystems. Robust quantitative estimates of MP extents and featured diversity are the basis for comprehending their environmental implications precisely, and of these methods, membrane-based characterizations predominate with respect to MP inspections. However, though crucial to filter-based MP quantification, aggregation statuses of retained MPs on these substrates remain poorly understood, leaving us a “blind box” that exaggerates uncertainty in quantitive strategies of preselected areas without knowing overview loading structure. To clarify this uncertainty and estimate their impacts on MP counting, using MP imaging data assembled from peer-reviewed studies through a systematic review, here we analyze the particle-specific profiles of MPs retained on various substrates according to their centre of mass with a fast-random forests algorithm. We visualize the formation of distinct galaxy-like MP aggregation—similar to the solar system and Milky Way System comprised of countless stars—across the pristine and environmental samples by leveraging two spatial parameters developed in this study. This unique pattern greatly challenges the homogeneously or randomly distributed MP presumption adopted extensively for simplified membrane-based quantification purposes and selective ROI (region of interest) estimates for smaller-sized plastics down to the nano-range, as well as the compatibility theory using pristine MPs as the standard to quantify the presence of environmental MPs. Furthermore, our evaluation with exemplified numeration cases confirms these location-specific and area-dependent biases in many imaging analyses of a selective filter area, ascribed to the minimum possibility of reaching an ideal turnover point for the selective quantitive strategies. Consequently, disproportionate MP schemes on loading substrates yield great uncertainty in their quantification processing, highlighting the prompt need to include pattern-resolved calibration prior to quantification. Our findings substantially advance our understanding of the structure, behavior, and formation of these MP aggregating statuses on filtering substrates, addressing a fundamental question puzzling scientists as to why reproducible MP quantification is barely achievable even for subsamples. This study inspires the following studies to reconsider the impacts of aggregating patterns on the effective counting protocols and target-specific removal of retained MP aggregates through membrane separation techniques.

A Theory of Power Structure and Institutional Compatibility: China versus Europe Revisited

Abstract To better understand institutional differences across space and time, we propose a two-dimensional framework of the power structure among three players in society: the degree of absolute power of the Ruler over the Elites and the People, and the degree of asymmetry between the latter two in terms of their everyday rights and power. Within this framework, we show that a more absolutist Ruler prefers a more balanced Elite–People relationship. This theory helps in particular to reconcile views on the comparison between imperial China and premodern Europe that would seem contradictory in one-dimensional or two-estate frameworks: the Ruler’s absolute power was weaker in Europe, whereas the Elite–People relationship was more balanced in China. Our approach also helps more generally to interpret specific institutions and other variations in power structures.
