A Study on the Interaction Between Population Mobility and High-Quality Development of Manufacturing Industry in China —Based on the Data of Fujian Province

This paper uses relevant mathematical statistical models to verify the interactive effect between population mobility and the high-quality development of the manufacturing industry based on the panel data of 43 counties in the Fujian province from 2007 to 2021. The results show that (1) the inflow areas of population flow in the Fujian province are mainly concentrated in the southeast region; (2) there is mutual promotion between population mobility and the high-quality development of the manufacturing industry in the Fujian province, and the population mobility in adjacent areas has a significant promotion effect on the high-quality development of the local manufacturing industry; and (3) heterogeneity results show that after 2011, the interaction effect between population mobility and the high-quality development of the manufacturing industry has declined, and population inflow has a stronger role in promoting the high-quality development of the manufacturing industry than population outflow. The conclusions of this study are of great significance to the Fujian province for implementing a reasonable population policy and promoting the coordinated development of manufacturing enterprises.

Radix Actinidiae chinensis induces the autophagy and apoptosis in renal cell carcinoma cells

BackgroundRenal cell carcinoma (RCC) is a malignant tumor. Radix Actinidiaechinensis (RAC) is the root of Actinidia arguta (Sieb. et Zucc) Planch. ex Miq. In clinical research, RAC was confirmed to have a certain anti-tumor effect, including liver cancer and cholangiocarcinoma. This study investigated the anticancer effect and mechanism of RAC in RCC cells.MethodsThe 786-O and A498 cells were intervened with varying concentrations of RAC (0–100 mg/mL) to detect the half maximal inhibitory concentration (IC50) of RAC. The cells were then co-cultured with 0–50 mg/mL RAC for 0–72 h to assess the effect of RAC on cell viability using the cell counting kit-8. The effects on cell proliferation, cell cycle or apoptosis, migration or invasion, and autophagy were detected using cloning, flow cytometry, Transwell, AOPI assay and Western blot. The number of autophagolysosomes was quantified using a transmission electron microscope. PI3K/AKT/mTOR pathway-related proteins were detected by Western blot. Additionally, an autophagy inhibitor 3-MA was used to explore the underlying mechanism of RAC.ResultsIC50 values of RAC in 786-O and A498 were 14.76 mg/mL and 13.09 mg/mL, respectively. RAC demonstrated the ability to reduce the cell malignant phenotype of RCC cells, blocked the S phase of cells, promoted apoptosis and autophagy in cells. Furthermore, RAC was observed to increase autophagy-related proteins LC3II/I and Beclin-1, while decreasing the level of P62. The expression of apoptosis-related proteins was increased, while the ratios of p-PI3K/PI3K, p-AKT/AKT, p-mTOR/mTOR, p-P38/P38 and p-ERK/ERK were reduced by RAC. However, the addition of 3-MA reduced the apoptosis and autophagy- promotion effects of RAC on RCC cells.ConclusionRAC induced the apoptosis and autophagy, to inhibit the progression of RCC cells. This study may provide a theoretical and experimental basis for clinical anti-cancer application of RAC for RCC.

Effects of promoter and dedoping process on electrorheological response of polyaniline-graft-chitosan copolymer

In this study, electrorheological (ER) properties of biodegradable and conducting polyaniline-graft-chitosan (PAni-g-CS) copolymer particles were investigated. For this purpose, PAni and PAni-g-CS particles were synthesized by using in situ oxidative radicalic polymerization method. At first, PAni and PAni-g-CS/silicone oil (SO) ER suspensions (15% V/V) were subjected to external electric field and they exhibited low ER activity. When the external electric field strengths ([Formula: see text] were increased, both the suspensions showed electrical breakdown. Therefore, virgin PAni and PAni-g-CS were first subjected to dedoping process by treating with 1.0 M NaOH(aq) and non-ionic surfactant Triton X-100 (T-X) surfactant to enhance the expected ER activity and prevent the electrical breakdown. But we observed that the addition of T-X as promoter had no significant effect on the ER activity. On the other hand, electric filed-induced viscosities of both the suspensions were observed to enhance after the dedoping (DD) process and electrical breakdown prohibited. After the DD process, DD PAni-g-CS/SO ER system exhibited the highest electric field-induced viscosity by reaching 400[Formula: see text]Pa[Formula: see text]⋅[Formula: see text]s at [Formula: see text][Formula: see text]kV/mm. The highest ER efficiency was also obtained for DD PAni-g-CS/SO system at 15% (V/V) as 79. Additionally, typical shear thinning non-Newtonian viscoelastic behavior was observed under externally applied E. The conduction model of DD PAni-g-CS/SO system was determined to well fit the conduction model by showing a slope of [Formula: see text] calculated from the E vb. yield stress graph. In conclusion, conducting and biodegradable-dedoped PAni-g-CS particles would be a good candidate for potential ER applications as dry-based ER materials having high colloidal stability of 76%.

Weakening Mn-O Bond Strength in Mn-Based Perovskite Catalysts to Enhance Propane Catalytic Combustion.

Exploring highly efficient and robust non-noble metal catalysts for VOC abatement is crucial but challenging. Mn-based perovskites are a class of redox catalysts with good thermal stability, but their activity in the catalytic combustion of light alkanes is insufficient. In this work, we modulated the Mn-O bond strength in a Mn-based perovskite via defect engineering, over which the catalytic activity of propane combustion was significantly enhanced. It demonstrates that the oxygen vacancy concentration and the Mn-O bond strength can be efficiently modulated by finely tuning the Ni content in SmNixMn1-xO3 perovskite catalysts (SNxM1-x), which in turn can enhance the redox ability and generate more active oxygen species. The SN0.10M0.90 catalyst with the lowest Mn-O bond strength exhibits the lowest apparent activation energy, over which the propane conversion rate increases by 3.6 times compared to that on the SmMnO3 perovskite catalyst (SM). In addition, a SN0.10M0.90/cordierite monolithic catalyst can also exhibit a remarkable catalytic performance and deliver excellent long-term durability (1000 h), indicating broad prospects in industrial applications. Moreover, the promotional effect of Ni substitution was further unveiled by density functional theory (DFT) calculations. This work brings a favorable guidance for the exploration of highly efficient perovskite catalysts for light alkane elimination.

Mental health inequality between urban and rural youth under COVID-19 from survey data from China

BackgroundWhile health inequality has been the focus of past scholarly discussions, COVID-19’s outbreak and spread have provided a new arena for discussing health inequality, particularly in the context of urban–rural disparities in China. This paper explores the impact of COVID-19 on urban–rural health inequality, and the roles played by socioeconomic status and social capital.MethodsA cross-sectional observational collected data on demographics, mental health, socioeconomic status, and social capital. An online survey was administered from August 27 to August 30, 2020, and, 1936 valid samples were received. Mental health was measured using the Brief Symptom Inventory (BSI-18). This study applied the ordinary least squares regression (OLS) model, and data analysis was performed using STATA.ResultsThere were 1936 participants, with an equal distribution of genders. Multiple regression analysis showed that the mental health levels of rural youth were superior to those of urban youth (p = 0.049), especially when the epidemic was not severe (p = 0.013). Socioeconomic status had a significant positive promotion effect on mental health (p = 0.008), but the interaction effect between socioeconomic status and the urban–rural divide indicated that the promotion effect of socioeconomic status on the mental health of urban youth was greater than that of rural youth (p = 0.04). Social capital had a significant positive promotion effect on mental health (p = 0.000), and the interaction effect indicated that this promoting effect did not differ between urban and rural areas (p > 0.05).

Neferine alleviates ovariectomy-induced osteoporosis by enhancing osteogenic differentiation of bone marrow mesenchymal stem cells via regulation of the p38MAPK pathway

ABSTRACT Objective Osteoporosis, a skeletal ailment marked by bone metabolism imbalance and disruption of bone microarchitecture, Neferine, a bisbenzylisoquinoline alkaloid with diverse pharmacological activities, has received limited attention in the context of osteoporosis treatment. Methods We employed a bilateral ovariectomy (OVX) rat model to induce osteoporosis and subsequently administered Neferine treatment for four weeks following successful model establishment. Throughout the modeling and treatment phases, we closely monitored rat body weights. We assessed alterations in bone tissue microstructure through micro-CT, HE staining, and safranin O-fast green staining. Levels of bone formation and resorption markers in serum were evaluated using ELISA assay. Western blot analysis was employed to determine the expression levels of p38MAPK, p-p38MAPK, and bone formation-related genes in bone tissue. We isolated and cultured OVX rat BMSCs (OVX-BMSCs) and induced osteogenic differentiation while simultaneously introducing Neferine and the p38MAPK inhibitor SB203580 for intervention. Results Neferine treatment effectively curbed the rapid weight gain in OVX rats, ameliorated bone loss, and decreased serum levels of TRAP, CTX-I, PINP, and BALP. Most notably, Neferine promoted the expression of bone formation-related factors in bone tissue of OVX rats, while concurrently activating the p38MAPK signaling pathway. In in vitro experiments, Neferine facilitated the expression of bone formation-related factors in OVX-BMSCs, increased the osteogenic differentiation potential of OVX-BMSCs, and activated the p38MAPK signaling pathway. Nevertheless, SB203580 partially reversed Neferine’s promotive effect. Conclusion Neferine can boost the osteoblastic differentiation of BMSCs and alleviate OVX-induced osteoporosis in rats by activating the p38MAPK signaling pathway.

The Third Compound Promoted Copolymerization of Ethylene with 4‐Penten‐1‐ol by Using Metallocene Catalyst

AbstractOlefin coordination copolymerization with polar monomers is an important topic both in academia and industry. During copolymerization, polar monomers will seriously reduce the polymerization activity and the molecular weight of the copolymer, making it difficult to balance the two and the polar monomer incorporation at the same time. In this study, a metallocene catalyst, Ph2C(Cp)(Flu)ZrCl2, was used for the copolymerization of ethylene with 4‐penten‐1‐ol. The incorporation of 4‐penten‐1‐ol can be effectively increased by the introduction of the steric phenol as the third component. Depending on the cocatalyst, the activity or molecular weight can be improved. It is believed that the promotion effect may work by the interaction of the steric phenol with the catalyst or cocatalyst. It is also suggested that in this system, polymerization is terminated by deactivation‐chain transfer mechanism rather than β‐X elimination due to back‐biting.This article is protected by copyright.

Analysis on promotive effect of rocking culture on keratinocyte differentiation in three-dimensional reconstitution human epidermis.

A three-dimensional culture system of keratinocytes achieves cornification as a terminal differentiation that can mimic the formation of stratified epidermis. At the onset of keratinocyte differentiation, air-exposure treatment is essential for promotion. We have previously reported that the stimulation of differentiation is accompanied by down-regulation of the transcriptional activity of the hypoxia-inducible factor (HIF) and also found that rocking treatment of cultured keratinocytes in the submerged condition restored their differentiation. A comparative study between with and without rocking was then carried out to investigate the characteristics of the recovered differentiation by morphological and biochemical analysis. In addition, transcriptome analysis revealed the expected similar pattern between air-exposure and rocking culture, including HIF-regulating transcripts. Furthermore, the promotive effect of rocking treatment was impaired under hypoxic culture conditions (1% O2). We showed that the restored promotion of differentiation by rocking culture is mainly due to the abrogation of transcriptional events by hypoxia.

Since the 21st century, with the development of the Internet, online education has gradually become an important trend in the development of the education industry. The motivation of online learning has also received extensive attention and research in the academic community, but compared with the external motivation, the specialized research of internal motivation is less. Therefore, this paper will base on the influence of Bruner's intrinsic motivation theory on online learning, and analyse the relationship between three elements of internal motivation and synchronous online learning and asynchronous online learning. Combined with the existing online learning software and platform, this paper analyses and summarizes the promotion effect of internal motivation on online learning, and puts forward some own views and opinions.

The heterogeneous impact of China–Europe railway express on the efficiency of logistics industry in node cities

PurposeThe spatiotemporal compression effect of China–Europe Railway Express (CR-Express) can reduce the flow costs of resources between China’s node cities. Additionally, it can break through the limitations of low-added-value marine products, significantly impacting the logistics industry efficiency. However, there are few literature verifying and analyzing its heterogeneity. This study explores the impact of CR-Express on the efficiency of logistics industry in node cities and analyzes the heterogeneity.Design/methodology/approachFirst, this study uses panel data to measure the efficiency of node city logistics industry. Secondly, this study discusses the impact of the opening of CR-Express on the efficiency of logistics industry in node cities based on the multi-period differential model. Finally, according to the node city difference, the sample city experimental group is grouped for heterogeneity analysis.FindingsThe results show that CR-Express can promote the urban logistics industry efficiency, with an average effect of 4.55%.

The improvement effect of node cities and central cities in central and western China is stronger, especially in the sample of megacities and type I big cities. Compared with non-value chain industrial products, the CR-Express has significant promotion effects on the logistics efficiency of the cities where main goods are value chain products.Originality/valueUnder the background of double cycle development, this paper can provide a scientific basis for the investment benefit evaluation of CR-Express construction and the follow-up route planning.

Evaluating the Impact of Low-Carbon Urban Policy on Corporate Green Innovation—Evidence from China’s National Low-Carbon City Strategy Program

Low-carbon urban policy (LCUP) and corporate green innovation are considered crucial strategies and methods for reducing urban carbon emissions, addressing climate change, and promoting urban environmental sustainability. This study constructed a quasi-natural experiment based on the low-carbon city strategy program implemented in China in 2010, utilizing data from Chinese prefecture-level cities and publicly listed companies from 2005 to 2020. Employing a multi-period difference-in-differences (DID) approach, this paper reveals that the establishment of low-carbon model cities effectively fosters green innovation in corporations. Further analysis demonstrates that this promotional effect is particularly significant in non-state-owned enterprises, enterprises with high media attention, those with a high level of digitalization, and enterprises located in cities with high levels of green finance and in the Eastern and Central regions of China. These conclusions withstood a series of robustness tests, confirming their validity. Meanwhile, the examination of policy mechanisms reveals that public environmental awareness, government environmental regulation, and corporate environmental information disclosure are three key policy transmission mechanisms through which LCUP affects corporate green innovation. The findings of this study provide significant empirical insights for addressing climate change and enhancing the sustainable capacity of urban environments.

Effect of Lanthanum and Iron Doping on Nickel‐Based Alumina and Ceria Supported Catalysts for Steam Reforming of Methane

AbstractMembrane reformers emerge as an efficient technology for ‘on‐site’ ultra‐pure hydrogen production. The membrane reformer can be integrated with PEM fuel cell (PEMFC) to provide power. However, as the PEMFC works at lower temperature hence, such integration requires a low temperature catalyst. Further, for successful integration of membrane reformer with PEMFC, a low CO selective catalyst is vital. In current work, Ni‐based alumina and ceria supported catalysts are used. The effect of La and Fe promoters on the performance of Ni‐based alumina and ceria supported catalysts are investigated. The catalysts are synthesized using wet impregnation method. A complete characterization of catalysts is performed using BET, XRD, FESEM, and EDX. Fe promoted catalysts shows low CO and high CO2 selectivity which is desirable for membrane reformer. However, the catalytic activity of Fe promoted Ni‐based alumina and ceria supported catalysts were low. La promoted Ni‐based catalysts show high catalytic activity on both alumina and ceria supported catalysts. La promoted catalysts also gives low start up time, high catalytic activity and low CO selectivity at low temperature. Ni−La/Al2O3 catalyst provides 50 % conversion and 12 % CO selectivity at 500 °C. This makes it suitable for ‘on‐site’ generation of ultra‐pure hydrogen through membrane reformer.

Tumour necrosis factor α regulates the miR-27a-3p-Sfrp1 axis in a mouse model of osteoporosis.

Osteoporosis is a metabolic bone disease that involves gradual loss of bone density and mass, thus resulting in increased fragility and risk of fracture. Inflammatory cytokines, such as tumour necrosis factor α (TNF-α), inhibit osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs), and several microRNAs are implicated in osteoporosis development. This study aimed to explore the correlation between TNF-α treatment and miR-27a-3p expression in BMSC osteogenesis and further understand their roles in osteoporosis. An osteoporosis animal model was established using ovariectomized (OVX) mice. Compared with Sham mice, the OVX mice had a significantly elevated level of serum TNF-α and decreased level of bone miR-27a-3p, and in vitro TNF-α treatment inhibited miR-27a-3p expression in BMSCs. In addition, miR-27a-3p promoted osteogenic differentiation of mouse BMSCs in vitro, as evidenced by alkaline phosphatase staining and Alizarin Red-S staining, as well as enhanced expression of the osteogenic markers Runx2 and Osterix. Subsequent bioinformatics analysis combined with experimental validation identified secreted frizzled-related protein 1 (Sfrp1) as a downstream target of miR-27a-3p. Sfrp1 overexpression significantly inhibited the osteogenic differentiation of BMSCs in vitro and additional TNF-α treatment augmented this inhibition. Moreover, Sfrp1 overexpression abrogated the promotive effect of miR-27a-3p on the osteogenic differentiation of BMSCs. Furthermore, the miR-27a-3p-Sfrp1 axis was found to exert its regulatory function in BMSC osteogenic differentiation via regulating Wnt3a-β-catenin signalling. In summary, this study revealed that TNF-α regulated a novel miR-27a-3p-Sfrp1 axis in osteogenic differentiation of BMSCs. The data provide new insights into the development of novel therapeutic strategies for osteoporosis.

Can Aluminum Cations Promote Nucleation for THF Hydrate Growth?

Rapid nucleation of tetrahydrofuran (THF) hydrate is essential for developing a THF hydrate-based cold storage technology. Earlier works have hypothesized the role of aluminum complexes in initiating the nucleation of clathrate hydrates using aluminum metal electrodes and substrates. This study investigates if the nucleation promotional effect of hydrate can be achieved using the aluminum salt, AlCl3, due to the formation of aluminum aqua complexes in water. Metal chlorides NaCl and MgCl2 are also utilized to evaluate the effect of cation type in initiating nucleation, i.e., the effect of charge/radius ratio. The induction time is measured in a stirred reactor at various subcoolings and concentrations of 0.05, 0.1, 0.5, 1, and 2 wt %. The nucleation time is studied in two reactor configurations based on the nature of salt introduction in the THF solution, i.e., salt premixed in solution and salt injected inside the solution. The sudden rise in the reactor temperature due to hydrate formation is used as an indicator of hydrate formation. Results indicate that AlCl3 promotes hydrate nucleation as AlCl3 reduces induction time by 92.2% at 0.05 wt % concentration compared with water. Nearly instantaneous nucleation is also achieved by directly injecting AlCl3. MgCl2 and NaCl do not show a similar effect on induction time as AlCl3. The pH and Raman spectra measurements with and without salts are carried out to explain the effect of cations on the THF-water solution.

Institutional Investors’ Green Activism and Corporate Green Innovation: Based on the Behind-Scene Communications

ABSTRACT This paper investigates the promotion effects of institutional investors’ communication on corporate green innovation. We use content analysis to identify the efficiency of institutional investors’ communication, and find that institutional investors’ communication promotes corporate green innovation. The mechanism analysis indicates that institutional investors’ communication improves managers’ awareness of green transformation, promotes corporate green investment efficiency and mitigates the extent of greenwashing. The positive impacts of institutional investors’ communication are more effective on corporate utility patents than on invention patents. Such green governance effects are more pronounced in non-state-owned firms, green investors and close-distance to the institutional investors. By introducing exogenous shocks of the New Environmental Protection Law and China’s regional carbon emissions trading market pilots, we find that the impact of institutional investors’ communication on green innovation is enhanced after the implementation of environmental policies. Overall, our research contributes to the existing literature on institutional investors’ green activism and the factors of green innovation, and also enriches the cross-disciplinary research on environmental regulation affecting institutional investors’ green governance.

Study on the stability of molecular chirality and the configuration protection of dihydromyricetin in vine tea.

This study aims to investigate the impact of four key factors, namely, temperature, water source, metal ion, and pH, on the stability of molecular chirality of dihydromyricetin (DMY) and proposed effective strategies for configuration protection. The findings reveal that temperatures exceeding 80°C could accelerate the racemization process of DMY, with a significant increase in racemization observed at 100°C. In addition, DMY exhibited heightened stability in ultrapure water as compared to various water sources, including pure water-1, pure water-2, mineral water, and running water. Notably, the presence of Fe2+ displayed an inhibitory effect on the racemization of DMY, whereas Mg2+, Ca2+, and Mn2+ showed a substantial promotional effect. Additionally, acidic conditions (pH<5.0) were found to be protective for maintaining the stability of DMY, whereas alkaline conditions (pH>9.0) were observed to be detrimental. Meanwhile, we first identified the presence of another pair of DMY isomers in this work.

Characterization of Bacillus velezensis DCJ 2 isolated from the rhizosphere soil of aglaonema ‘Maria’ and investigation of its plant growth-promoting effects

Aglaonema ‘Maria’ is one of the key foliage plants that has gained high demand in foreign destinations in the last few years. This study was conducted to characterize Bacillus velezensis DCJ 2, assess its plant growth promotion effect and investigate the effectiveness of different delivery methods of the bacterial inoculum for the growth promotion of Aglaonema ‘Maria’. In this context, DCJ 2, isolated from the rhizosphere soil of A. Maria was screened to investigate its potential as a plant growth-promoting bacterium. The pure culture of DCJ 2 maintained on nutrient agar was utilized for morphological, biochemical and physiological examinations. The molecular characterization of the strain was performed with different primer pairs targeting 16SrRNA, gyrA, pgsB and sugar kinase genes of DCJ 2. A pot experiment was carried out to investigate the plant growth promotion effect. It was conducted in the greenhouse as per the complete randomized block design with eight treatments and five replicates. . Healthy plants of A. ‘Maria’ established in field soil and solarized soil were treated with 100 ml of the suspension of the DCJ 2 at the rate of 10 8 CFU/ml either as a soil drench or foliar spray. The partial 16SrRNA, gyrA, pgsB and sugar kinase gene sequences of DCJ 2, BLAST searched in the NCBI database revealed that it has a high similarity to Bacillus velezensis. The pot experiment showed that the application of strain DCJ 2 as a soil drench to solarized soil (Treatment 6) yielded a significant increase in growth parameters at p=0.05. Based on molecular analysis, morphological, biochemical, and physiological reactions, DCJ 2 was identified as Bacillus velezensis. This study revealed that B. velezensis DCJ 2 has the potential to boost the growth of A. Maria and hence serve as a base for developing a biofertilizer.
