Article Stiffness evaluation of semi-rigid connection using steel clamps in plastic greenhouse structure Greenhouse structures, essential for modern agriculture, often experience significant uncertainties due to varying environmental conditions, leading to frequent damage and economic losses. Accurately analysing the structural responses of these greenhouses is particularly challenging due to the difficulty in understanding the actual behaviour of connections using steel clamps. This study focuses on evaluating the stiffness and mechanical behaviour of semi-rigid connections using steel clamps in plastic greenhouses. A specialised load-deformation testing apparatus was developed to assess the relationships between force and displacement or moment and rotation for these connections with various deformation modes. The experimental results were used to model stiffness coefficients and ultimate limit loads, providing a detailed understanding of the mechanical properties of these connections. Findings reveal that steel clamps introduce complex structural behaviours that differ significantly from traditional connections, highlighting the need for advanced modelling techniques. This comprehensive analysis offers new insights into the behaviour of semi-rigid connections in greenhouse structures and underscores the importance of detailed empirical studies. The research contributes to improving the structural design and safety assessments of agricultural facilities, ensuring better resilience against environmental stresses. The outcomes are crucial for developing more effective and reliable greenhouse designs that can withstand adverse conditions, ultimately supporting sustainable agricultural practices.

Article Understanding of enhanced nitrate in fine particles at agricultural sites in summer with high ammonia level☆ Nitrate is one of the major constituents of fine particles and has not been effectively alleviated in Northeast Asia. Field measurements of various gases and the chemical composition of fine particles were conducted at two agricultural sites (cropland and livestock) in ammonia-rich environments to understand the effect of ammonia on nitric acid-nitrate partitioning using a thermodynamic model and to suggest a possible strategy to control total nitrate (i.e., nitric acid formation). High nitrate levels were observed at the agricultural sites in summer compared to those at the urban sites. It was found that high level of ammonia in summer led to increased aerosol pH and nitrate fraction. At the cropland site in summer, the daily nitrate fraction was particularly sensitive to aerosol pH, suggesting that ammonia reduction should be effective in decreasing nitrate formation via nitric acid- nitrate partitioning (with a 50% reduction in ammonia, nitrate concentration can decrease by 34%). Aerosol water content also played a significant role in determining nitrate fraction in the aerosol pH range of 2.5-3.0. It was found that the sites were under high NOx conditions, and that the reduction of OH production (daytime) and O3 (nighttime) was important for controlling total nitrate, but this is challenging due to the high contributions of background O3. It was concluded that the reduction of ammonia emissions for the control of the nitrate fraction via gas-to-particle partitioning should be important to mitigate nitrate in fine particles at agricultural sites in summer.

Article Multifunctional PDMS/Coal gasification fine slag composites for enhanced electromagnetic shielding and thermal management Coal gasification fine slag (CGFS), a representative challenging solid waste in the coal chemical industry, has garnered significant attention due to its high carbon content and inorganic oxide components. Notably, the magnetic Fe3O4 particles are uniformly distributed within the CGFS matrix, rendering it a natural magneticdielectric composite material. Capitalizing on this unique characteristic, this study innovatively proposes the application of CGFS in the field of EMI shielding. Through a facile solution blending-hot pressing process, flexible PDMS/CGFS composites were fabricated. The results demonstrate that with a CGFS loading of 40 wt%, the composite achieves an average shielding effectiveness of 34.7 dB in the X-band, significantly surpassing the commercial standard of 20 dB. Simultaneously, the composite exhibits an absorption coefficient (A) of 0.35, effectively mitigating secondary radiation pollution. Additionally, the PDMS/CGFS composite also possesses multifunctional characteristics, including thermal conductivity, Joule heating, and photothermal conversion capabilities. Therefore, this study not only provides an innovative approach for the utilization of CGFS but also opens new research directions for developing novel multifunctional EMI shielding materials.

Article Obtaining both high CO2 adsorption capacity and CO2/N2 selectivity via blocking N2 adsorption sites by grafting bulky diamine on metal-organic framework Functionalizing metal-organic frameworks (MOFs) with alkyl amines has been employed in various studies for CO2 adsorption because of their high efficiency in CO2 capture. However, a trade-off between the high CO2 adsorption and high CO2/N-2 selectivity has been usually observed. To achieve both, we focused on reducing the amount of N-2 adsorption while maintaining the CO2 adsorption capacity of alkyl amines. In this study, a bulky diamine was grafted onto coordinatively unsaturated sites of Cr-based MOFs (MIL-101) instead of a non-bulky (normal or linear) diamine of the same length (from amine to amine). The bulky diamine blocked the N-2 adsorption sites (not useful sites for CO2 adsorption), reducing N-2 adsorption more than the non-bulky diamine. On the other hand, the CO2 adsorption amount remained unchanged, especially under low pressure ( 1 mmolg(-1)) and large CO2/N-2 selectivity (> 100) at 100 kPa and 298 K.

Article Oligodendrocyte Precursor Cell-Specific HMGB1 Knockout Reduces Immune Cell Infiltration and Demyelination in Experimental Autoimmune Encephalomyelitis Models Infiltration and activation of peripheral immune cells are critical in the progression of multiple sclerosis and its experimental animal model, experimental autoimmune encephalomyelitis (EAE). This study investigates the role of high mobility group box 1 (HMGB1) in oligodendrocyte precursor cells (OPCs) in modulating pathogenic T cells infiltrating the central nervous system through the blood-brain barrier (BBB) by using OPC-specific HMGB1 knockout (KO) mice. We found that HMGB1 released from OPCs promotes BBB disruption, subsequently allowing increased immune cell infiltration. The migration of CD4+ T cells isolated from EAE-induced mice was enhanced when co-cultured with OPCs compared to oligodendrocytes (OLs). OPC-specific HMGB1 KO mice exhibited lower BBB permeability and reduced immune cell infiltration into the CNS, leading to less damage to the myelin sheath and mitigated EAE progression. CD4+ T cell migration was also reduced when co-cultured with HMGB1 knock-out OPCs. Our findings reveal that HMGB1 secretion from OPCs is crucial for regulating immune cell infiltration and provides insights into the immunomodulatory function of OPCs in autoimmune diseases. © Center for Excellence in Brain Science and Intelligence Technology, Chinese Academy of Sciences 2025.

Article Room-temperature oxidative desulfurization with tungsten oxide supported on NU-1000 metal-organic framework A homogeneously dispersed and immobilized tungsten oxide (WO3) catalyst supported on a metal-organic framework (MOF) NU-1000 was prepared for the first time and applied for the oxidation of organic sulfur compounds (OSCs) from liquid fuels. The composite was prepared at room temperature; therefore, cost-effective and environmentally friendly. The defective sites of NU-1000 helped the firm immobilization of WO3 species within the NU-1000 pores. The composite material denoted as W@NU-1000 was prepared from ammonium tungstate para pentahydrate in the presence of NU-1000 using nitric acid as a precipitating agent. The material was characterized by several techniques including XRD, FTIR, TGA, N2 adsorption-desorption, XPS, SEM, and TEM. The material showed remarkable performances in the oxidative conversion of dibenzothiophene (DBT, a typical OSC) using H2O2 as an oxidant. For example, almost complete conversion of DBT (1000 ppm) was achieved at room temperature within 120 min of the reaction, and the activation energy was very low of 25.9 kJmol- 1. The remarkable performance of the catalyst might be due to the well-dispersed WO3 (that can effectively activate H2O2) and relatively high porosity. The radical scavenger experiments and electron spin resonance analyses confirmed a non-radical pathway for the oxidation of DBT probably by the formation of a W6+-peroxo complex during the oxidation process. The material W@NU-1000 could be used for five cycles without any loss in performance, suggesting that it can be utilized as a potential oxidation catalyst.

Article Selective enrichment of electrode-associated cells enhances CO2 conversion to acetate in microbial electrosynthesis cells Microbial Electrosynthesis (MES) converts CO2 into valuable products (e.g., acetate, volatile fatty acids, and CH4) through electron transfer facilitated by electroactive bacteria. Both electrode-attached and suspended cells can obtain reducing power from electron donors such as electrode and by-products (e.g., H2, formate) in MES. This study compared the performance of electrode-attached and suspended cells for acetate production. Potential application and periodic medium replacement at different rates were applied to enrich electrode-attached cells selectively. H2 and formate were each used as electron donors for suspended cells, and the addition amounts were pre-adjusted to ensure a constant cycle. As a result, the electrode-attached cells with 100% medium replacement achieved the highest acetate production (0.50 f 0.02 g/L/day) and Coulombic efficiency (86 f 3.4%), whereas 50% medium replacement with both electrode-attached and suspended cells was slightly lower (0.36 f 0.01 g/L/day, 77 f 2.1%). The formate-augmented and H2-augmented MES produced only 0.29 f 0.01 and 0.17 f 0.01 g/L/day of acetate, respectively. Field emission scanning electron microscopy revealed an aggregated electrode-attached biofilm and mediators supporting direct electron transfer. In separated cultures in serum bottles, electrode-attached cells showed higher protein content and specific acetate production rate, which were higher than those of suspended cells. A comparison of the performance of electrode-attached/suspended cells through selective enrichment suggested that the electron transfer of electrode-attached cells can improve the CO2 conversion and efficiency of MES.

Article Strategic conversion of industrial plastic waste into transportation fuel using iron and strontium containing metal waste as a catalyst Metal waste (MW) produced from different manufacturing companies has been considered a hazardous material and discarded in secured landfilling sites. The complicated chemical composition of MW made it difficult to be used as a beneficial material. When the hazardous waste is reused as a useful material, waste recycling with the minimization of hazardous waste landfilling could be achieved. In this study, MW from magnetic materials producing from facilities was utilized as a catalyst for conversion of polyethylene based industrial plastic waste (IPW) into more valuable transportation fuel. Without MW catalyst, IPW was converted into long chained HCs at 600 & ring;C. Multi-zone pyrolysis further degraded them into shorter ones (average carbon length: C17), but the carbon chain length was still higher than those of diesel and aviation fuels. MW catalyst enhanced the C-C and C-H bond scissions, producing C7-16 HCs and H2 as major components. The catalytic activity was attributed to the presence of transition and alkaline (earth) metal (oxide) such as Iron (oxide), Strontium (oxide), and their alloys in MW. IPW plastic oil from catalytic pyrolysis (C13.22H25.86 for 45.99 MJ kg-1) had similar chemical formula and heating value of petrodiesel (C12.3H22.2 for 42.5 MJ kg-1) and jet fuel (C10.17H19.91 for 43.23 MJ kg- 1). Therefore, this study demonstrated that the hazardous MW from industry could be employed as a catalyst for conversion of low-quality plastic oil into higher quality transportation fuel.

Article A Pharmacokinetic/Pharmacodynamic Study of Esomeprazole Comparing a Dual Delayed-Release Formulation (YYD601) to a Conventional Formulation Following Multiple Administrations in Healthy Adult Subjects Background: YYD601 is a new dual delayed-release formulation of esomeprazole, developed to enhance plasma exposure and prolong the duration of acid suppression. Purpose: This study aimed to evaluate the safety, pharmacokinetic (PK), and pharmacodynamic (PD) profiles of YYD601 20 mg following single and multiple oral administrations in healthy, fasting adult Koreans, and to compare these outcomes to those of the conventional esomeprazole 20 mg capsule. Methods: A randomized, open-label, two-period crossover study was conducted in 28 participants, who were divided into two treatment groups: one group received YYD601 20 mg, and the other received conventional esomeprazole 20 mg, once daily for five consecutive days. Blood samples for PK analysis were collected pre-dose and up to 24 hours post-dose. The primary PK parameters (AUC(last) and AUC(tau)) were evaluated. PD endpoints included integrated gastric acidity, percentage of time with intragastric pH > 4 over 24-hour and nighttime intervals, and percent change in serum gastrin levels after multiple dosing. Results: A total of 22 participants completed the study. YYD601 displayed more prolonged plasma concentration-time profiles than the conventional formulation, although the extent of the systemic exposure (AUC values) showed no statistically significant difference between the two formulations. With regard to the 24-hour gastric acid inhibition, YYD601 was comparable to the conventional formulation. The YYD601 showed a greater tendency for acid inhibition at night, as indicated by the percentage change of time with nocturnal acid breakthrough and other PD parameters. Both treatments were well tolerated, with no serious adverse events reported. Conclusion: Through extended systemic exposure of esomeprazole, YYD601 produces gastric acid suppression that is comparable to that of the conventional esomeprazole formulation, with a greater tendency to suppress acid at night. YYD601 20 mg was safe and well tolerated following single and multiple oral administrations, supporting its use as an effective alternative to conventional esomeprazole therapy.

Methods: The LC-MS/MS method for steppogenin was validated and used to investigate the pharmacokinetics of steppogenin in mice. A calibration curve was prepared in the range of 1–1,000 ng/mL of calibration standards and three levels of quality control samples (3, 125, and 750 ng/mL). Thereafter, the pharmacokinetics and BA of steppogenin were investigated following its administration via four different routes (i.e., intravenous [IV], subcutaneous [SC], intraperitoneal [IP], and per oral [PO]). Results: The linearity, inter- and intra-day precision, accuracy, and stability results were within 15% of the coefficient of variance (CV, %). Mean recoveries and the matrix effect of steppogenin were 68.06–89.47% and 59.03–66.72% with less than 11.87% and 9.031% of CV, respectively. BA of steppogenin administered via IV, SC, IP, and PO was determined as 100%, 84.7–96.0%, 54.0–54.6%, and 5.73–10.0%, respectively. P-glycoprotein (P-gp) efflux and first-pass phase II metabolism could have led to the low PO and moderate IP BA of steppogenin. The co-administration of a P-gp inhibitor (i.e., verapamil or D-α-tocopherol polyethylene glycol 1000 succinate) significantly increased the oral BA of steppogenin by 315% and 149%, respectively. Conclusion: The favorable pharmacokinetic features of steppogenin administered as IV or SC injection could result in its better therapeutic efficacy than when administered IP or PO. To improve oral BA, formulation strategies could incorporate inhibitors of P-gp-mediated efflux and first-pass metabolism. © The Author(s) under exclusive licence to The Korean Society of Pharmaceutical Sciences and Technology 2025.

Article Increased lamina propria B cells play roles in fructose-induced hypertension of Dahl salt-sensitive rats Aims: Although the immune system participates in the development of hypertension, the proportional contributions of distinct immune cells remain poorly understood. With the development of transcriptomics, we can profile the transcriptomes of individual immune cells and assess the relative contribution of each immune cell to the development of hypertension. So, we tested the hypothesis that increased lamina propria B cells play roles in fructose-induced hypertension of Dahl salt-sensitive (SS) rats. Materials and methods: Eight-week-old Dahl SS and Dahl salt-resistant (SR) male rats were divided into four groups; each group received either tap water (TW) or a 20 % fructose solution (HFS) for 4 weeks. Systolic blood pressure was measured using the tail-cuff method. Single-cell RNA sequencing (scRNA-seq) analysis was performed on lamina propria (LP) cells and peripheral blood mononuclear cells (PBMCs) obtained from the SS and SR rats subjected to either TW or HFS. Key findings: Results revealed that high-fructose intake induced hypertension in the SS rats but not in the SR rats. It also increased B cells in LPs but not in PBMCs of the SS rats; their subsets showed increased follicular and na & iuml;ve B cells. Increased lamina propria B cells play roles in fructose-induced hypertension of SS rats. Significance: This finding suggest that targeting B cells could be a potential strategy to mitigate high blood pressure in fructose-induced hypertension.

Article Oral bioavailability enhancement of chrysin using a spray-dried solid dispersion formulation with sodium dodecyl sulfate and polyvinylpyrrolidone Purpose: Chrysin has many pharmacological activities but suffers from low bioavailability (BA) due to its poor solubility and intestinal first-pass effect. This study aimed to develop a chrysin formulation that enhances its BA by inhibiting intestinal metabolism and increasing solubility. Methods: A solid dispersion of chrysin (chrysin-SD) was prepared using the spray-drying method and characterized for solubility, metabolic inhibition, and pharmacokinetic properties of chrysin-SD in rats. Results: Sodium dodecyl sulfate (SDS) and polyvinylpyrrolidone (PVP) were selected as solubility-enhancing surfactants as well as inhibitors of chrysin glucuronidation and hydrophilic carriers, respectively. The optimized formulation had a chrysin: SDS: PVP ratio of 1:5:3 (w/w/w). Chrysin-SD increased chrysin solubility by 848-fold and the dissolution rate to 72.3% of the initial amount, compared to 3.11% for pure chrysin. This improvement was attributed to SDS, PVP, and the amorphous nature of chrysin-SD. Additionally, chrysin-SD increased absorptive permeability in the duodenum, jejunum, and ileum by 2.99- to 7.33-fold in rat models, without affecting secretory permeability. Chrysin-SD also suppressed the formation of chrysin glucuronide (chrysin-G), suggesting enhanced intestinal absorption through increased intestinal permeability and decreased intestinal glucuronidation. These findings were confirmed by a 19.7-fold increase in chrysin’s area under the curve (AUC) and a 93% reduction in the chrysin-G metabolic ratio compared to the pure chrysin group. Conclusion: The chrysin-SD formulation with a chrysin: SDS: PVP ratio of 1:5:3 (w/w/w) significantly enhanced chrysin’s BA. This strategy, which improves solubility, dissolution, and intestinal absorption while reducing metabolism, offers a promising approach for enhancing the oral BA of herbal medicines like chrysin. © The Author(s) under exclusive licence to The Korean Society of Pharmaceutical Sciences and Technology 2025.

Article Pharmacokinetics and tissue distribution of NXC736, a novel modulator for sphingosine-1 phosphate receptor 1 and 4, in rats Purpose: NXC736, a novel compound that acts on sphingosine-1-phosphate (S1P) receptor 1 and 4, can treat autoimmune disease. We aimed to develop and validate the analytical method for NXC736 and its active metabolite NXC736-phosphate and to assess their pharmacokinetics and tissue distribution in rats. Methods: We conducted animal studies to evaluate the oral absorption, distribution, excretion, and toxicokinetics of NXC736 and NXC736-phosphate in rats. Results: NXC736 is converted to NXC736-phosphate via sphingosine kinase pre-systemically and in the body after absorption. NXC736 exhibited rapid absorption and high hepatic clearance and was eliminated with half-life of 3–5 h. Dose normalized plasma exposure of NXC736 showed dose dependency in an oral dose range of 3–30 mg/kg and became saturated in the dose range of 37.5–150 mg/kg. Subsequently, the NXC736-phosphate conversion rate was decreased dose-dependently, suggesting sphingosine kinase saturation. After the repeated oral administration of NXC736 (37.5–150 mg/kg) for 28 days, NXC736-phosphate accumulation was less than 2-fold, and no toxicity was observed in any rat. Blood lymphocyte inhibition, a pharmacological marker for NXC736, occurred by approximately 35%, 53%, and 56% at NXC736 doses of 37.5, 75, and 150 mg/kg/day, respectively, but recovered in a few days to control levels, suggesting NXC736 exhibits reversible activity. Conclusion: These findings provided crucial insights into the pharmacokinetic profiles of NXC736 and NXC736-phosphate, including absorption, distribution, metabolism, and excretion, and can help bridge research into human studies and in planning and interpreting clinical trials. © The Author(s) under exclusive licence to The Korean Society of Pharmaceutical Sciences and Technology 2025.

Article EAEFA-R: Multiple learning-based ensemble artificial electric field algorithm for global optimization Adjusting the search behaviors of swarm-based algorithms is crucial for solving real-world optimization challenges. Researchers have developed ensemble strategies and self-adaptive mechanisms to enhance the optimization ability of individual algorithms by balancing global and local search capabilities. Inspired by these advancements, this paper proposes a physics-based artificial electric field algorithm with three improvement strategies and an attraction-repulsion operator (EAEFA-R) to enhance diversity and escape local optima. These strategies are probabilistically selected using a dynamic adaptation mechanism. The effectiveness of EAEFA-R is assessed through extensive analysis of exploration-exploitation dynamics and diversity, and it is evaluated on two real-parameter test suites, CEC 2017 and CEC 2022, across 10, 20, 30, 50, and 100-dimensional search spaces. Compared to fifteen state-of-the-art algorithms, including AEFA variants and other optimization algorithms, EAEFA-R demonstrates superior solution accuracy, convergence rate, search capability, and stability performance. The overall ranking highlights its exceptional potential for solving challenging optimization problems, outperforming other state-of-the-art algorithms across various dimensions.
